Cecal Torsion / Cecal Volvulus

Cecal torsion, also known as cecal volvulus, is a life-threatening surgical emergency in horses characterized by rotation of the cecum around its longitudinal axis or mesenteric attachments. This catastrophic event compromises blood supply to the cecal wall, leading to rapid tissue death if not corrected surgically within hours of onset. The cecum, a large fermentation chamber located at the junction of the small and large intestines, becomes twisted in a manner that occludes both the arterial supply bringing oxygenated blood and the venous drainage removing deoxygenated blood. This strangulating obstruction creates an acute abdominal crisis that demands immediate recognition and intervention.

Cecal torsion represents one of the less common but most serious forms of colic encountered in equine practice. Studies estimate that cecal volvulus accounts for approximately one to three percent of horses presenting for colic surgery, though its relative rarity should not diminish awareness of its severity. This condition can affect horses of any age, breed, or sex, though certain populations demonstrate elevated risk. Broodmares in the periparturient period, horses recovering from general anesthesia, and those with pre-existing cecal dysfunction appear overrepresented in case reports. The condition's rapid progression leaves little margin for diagnostic delay.

The impact of cecal torsion on equine health is profound and often fatal without prompt surgical correction. Unlike simple impactions or displacements that may respond to medical management, cecal torsion creates a strangulating obstruction that causes irreversible tissue damage within hours. The compromised cecal wall rapidly becomes devitalized, releasing toxins into the bloodstream and creating systemic inflammatory responses. Endotoxemia develops quickly, causing cardiovascular collapse and shock. Even with surgery, prognosis depends heavily on the duration of torsion and degree of cecal compromise at the time of intervention.

With immediate surgical intervention before cecal wall devitalization occurs, some horses with cecal torsion can survive and return to function. However, the overall prognosis remains guarded to poor compared to many other colic conditions requiring surgery. Success depends on rapid recognition of the emergency nature of the condition, immediate referral to a surgical facility, and operative correction before irreversible damage occurs. Understanding the clinical presentation and urgency of cecal torsion enables horse owners and primary care veterinarians to make the rapid decisions necessary to give affected horses the best chance of survival.

The primary causes of cecal torsion relate to anatomical factors that allow abnormal mobility of the cecum and conditions that disrupt normal cecal position and function. The equine cecum is normally anchored by mesenteric attachments and its connections to the ileum and right ventral colon, but these attachments allow some degree of movement. When combined with changes in cecal weight, gas accumulation, or altered motility, conditions favorable for rotation can develop. Prior cecal impaction, ileus, or dysmotility may predispose to abnormal positioning that precedes torsion. Gas distension of the cecum, whether from altered fermentation or proximal intestinal dysfunction, increases the organ's buoyancy and potential for displacement.

While cecal torsion does not demonstrate clear genetic or breed predisposition, certain breed-related factors may influence risk indirectly. Draft breeds with large gastrointestinal capacity may be more prone to significant gas accumulation. Performance breeds undergoing frequent anesthesia for orthopedic procedures face elevated post-anesthetic risk. Thoroughbred and Arabian broodmares may be overrepresented due to reproductive-associated risk factors. However, any horse of any breed can develop cecal torsion given appropriate predisposing circumstances, and breed alone should not influence clinical suspicion when appropriate signs are present.

Environmental and management factors associated with cecal torsion include situations that alter normal gastrointestinal motility and positioning. General anesthesia represents a significant risk factor, with post-anesthetic colic including cecal abnormalities well documented. The combination of prolonged recumbency, altered blood flow, and pharmacologically suppressed gut motility during anesthesia creates conditions favorable for cecal displacement. Hospitalization for other conditions, particularly when accompanied by dietary changes, stress, and reduced activity, may predispose to cecal dysfunction. Rolling behavior during colic episodes from other causes could potentially trigger cecal displacement in a compromised organ.

Risk factors for cecal torsion encompass both patient characteristics and situational elements. The periparturient period in broodmares creates elevated risk, possibly related to changes in abdominal space and hormonal influences on gut motility as parturition approaches and occurs. Prior colic episodes, particularly those involving the cecum, may indicate underlying dysfunction that predisposes to torsion. Large body size increases the mechanical forces involved if the cecum becomes displaced. Horses that are fed immediately before or shortly after exercise may face increased risk from the combination of altered blood flow and a full cecum. Recovery from any surgical procedure under general anesthesia warrants vigilance for post-operative cecal complications.

The pathophysiology of cecal torsion involves rapid progression from initial displacement through vascular compromise to tissue necrosis and systemic collapse. When the cecum rotates along its axis, blood vessels in the mesentery become twisted and occluded. Arterial occlusion prevents oxygenated blood from reaching cecal tissues, while venous occlusion traps deoxygenated blood and metabolic waste products within the organ. The cecal wall quickly becomes edematous, congested, and ischemic. Mucosal barrier function fails, allowing bacteria and endotoxins to translocate across the damaged wall into the peritoneal cavity and systemic circulation. Progressive cellular death releases additional inflammatory mediators. Without surgical correction, complete cecal necrosis occurs within hours, followed by rupture and fatal peritonitis. The speed of this deterioration underlies the emergency nature of this condition.

Early warning signs of cecal torsion may be minimal or absent before the sudden onset of severe colic, making anticipatory detection challenging. In some cases, horses exhibit subtle signs of discomfort or reduced appetite in the hours preceding acute torsion, potentially reflecting developing cecal dysfunction. Horses recovering from anesthesia should be monitored closely for any signs of abdominal discomfort, as post-anesthetic cecal problems can develop within the first 24 to 72 hours following surgery. Broodmares in late pregnancy or early postpartum deserve attention for any deviation from normal behavior. However, many cases of cecal torsion present without recognizable prodromal signs, emphasizing the importance of rapid response once acute symptoms appear.

Common symptoms of cecal torsion include sudden onset of moderate to severe colic that rapidly progresses in intensity. Affected horses typically demonstrate marked pain that is disproportionate to initial physical findings and poorly responsive to standard analgesic medications. Unlike simple impactions where pain may wax and wane, cecal torsion produces persistent, escalating discomfort that reflects ongoing vascular compromise. Horses may sweat profusely, paw aggressively, look at their flanks repeatedly, and attempt to roll. Complete anorexia develops immediately, and horses show no interest in food or treats that would normally attract their attention.

Behavioral changes in horses with cecal torsion reflect the severity of pain and rapidly developing systemic illness. Affected horses may become violent in their attempts to relieve discomfort, throwing themselves down and rolling repeatedly. Alternatively, some horses become profoundly depressed and reluctant to move as shock develops. Posturing as if to urinate without producing urine indicates referred abdominal pain. Horses may stand with legs positioned abnormally, attempting to find a position that reduces discomfort. Mental status deterioration from bright and responsive to dull and obtunded accompanies systemic inflammatory response development. Increased respiratory rate reflects both pain and developing metabolic derangements.

Physical signs of cecal torsion demonstrate the serious nature of the condition and help differentiate it from less critical problems. Heart rate elevation is typically marked, often exceeding 60 to 80 beats per minute early and potentially reaching 100 or more as shock progresses. Mucous membranes that initially appear pale may become injected with a toxic red line or progress to gray, purple, or muddy coloration indicating cardiovascular compromise. Capillary refill time prolongs beyond the normal two seconds, eventually becoming difficult to detect. Gut sounds are typically absent in all quadrants due to reflex ileus. Rectal examination may reveal the distended, tense cecum in an abnormal position, though findings can be difficult to interpret in a painful, moving horse.

Symptom progression in cecal torsion follows a rapid downward trajectory that distinguishes it from conditions amenable to medical management. Pain typically intensifies over the first several hours despite analgesic administration. Cardiovascular parameters deteriorate progressively as endotoxemia and shock develop. Abdominal distension may become visible as gas accumulates in the compromised cecum and secondary ileus affects other intestinal segments. Nasogastric reflux may develop as small intestinal function becomes impaired. Cold extremities, muscle fasciculations, and colic signs becoming less violent as the horse weakens indicate advanced shock. The horse's overall appearance shifts from acute distress to systemic collapse.

Emergency symptoms requiring immediate intervention include any signs suggesting strangulating obstruction or cardiovascular compromise. Heart rate persistently above 60 beats per minute that fails to decrease with analgesics indicates serious pathology. Toxic-appearing mucous membranes with prolonged capillary refill time reflect circulatory failure. Complete absence of gut sounds throughout the abdomen suggests intestinal crisis. Nasogastric reflux exceeding several liters indicates secondary small intestinal involvement. Progressive abdominal distension visible externally demonstrates ongoing gas accumulation. Any horse with these findings requires immediate surgical evaluation without delay for repeated medical treatment attempts. The difference between survival and death often depends on hours, making rapid transport to a surgical facility essential.

Physical examination in suspected cecal torsion must be conducted rapidly and efficiently to avoid delaying surgical intervention if indicated. Vital parameter assessment reveals the characteristic pattern of strangulating obstruction: elevated heart rate that may exceed 80 beats per minute, abnormal mucous membrane color ranging from pale to congested to toxic, prolonged capillary refill time, and often elevated respiratory rate. Auscultation typically reveals absent or markedly reduced gut sounds in all quadrants. The degree of pain and poor response to analgesics provides important clinical information. The examining veterinarian must quickly determine whether the presentation suggests a surgical emergency requiring immediate referral rather than a condition that might respond to medical management.

Diagnostic tests in cecal torsion cases serve to confirm the severity of the situation and prepare for surgery rather than to delay intervention for definitive diagnosis. Rectal examination is essential and may reveal a tense, gas-filled cecum in an abnormal location, often displaced toward the midline or pelvic inlet. The examination may be difficult in a horse demonstrating severe pain. Nasogastric intubation assesses for reflux indicating secondary small intestinal involvement and decompresses the stomach before anesthesia. Blood work including packed cell volume, total protein, lactate concentration, and basic chemistry provides prognostic information about systemic status. Elevated lactate levels correlate with tissue hypoxia and carry negative prognostic implications.

Advanced diagnostics are often limited by time constraints in true cecal torsion cases, though certain modalities may provide useful information if immediately available. Transabdominal ultrasound can visualize cecal wall thickness and assess for peritoneal fluid accumulation, both of which have prognostic significance. Thickened cecal wall suggests prolonged ischemia and compromised viability. Large amounts of turbid peritoneal fluid indicate serious intestinal compromise. Abdominocentesis, if time permits, provides peritoneal fluid for analysis; serosanguinous fluid with elevated nucleated cell counts and protein suggests intestinal devitalization. However, the decision to proceed with surgery should not await diagnostic results if clinical presentation strongly suggests strangulating obstruction.

Differential diagnosis for the acute presentation of cecal torsion includes other surgical colic conditions causing severe, unrelenting pain. Large colon volvulus produces similar cardiovascular compromise and requires identical urgency. Small intestinal strangulation from various causes presents with more prominent nasogastric reflux but comparable pain and shock. Severe cecal impaction may initially appear similar though typically progresses more slowly. Colitis causing acute endotoxemic shock can produce comparable vital sign abnormalities. The clinician integrates all available information while maintaining urgency appropriate to the situation. Often, the specific diagnosis becomes clear only at surgery, but the decision to operate should be based on the emergency nature of the presentation rather than awaiting diagnostic certainty.

Emergency treatment for cecal torsion begins immediately upon suspicion and continues through surgical preparation and transport to a referral facility. Pain management using potent analgesics such as detomidine combined with butorphanol or xylazine attempts to control violent behavior and allow initial assessment, though response is typically incomplete. Intravenous fluid therapy begins as rapidly as large-bore catheters can be placed, using hypertonic saline initially for rapid volume expansion followed by isotonic crystalloids. Nasogastric decompression prevents gastric rupture during transport and anesthesia induction. The primary veterinarian's role centers on patient stabilization and coordination of rapid transport to a surgical facility rather than attempting definitive treatment.

Medical management has essentially no role in treating true cecal torsion, as this strangulating obstruction cannot resolve without surgical intervention. Unlike impactions or simple displacements that may respond to enteral fluids and time, the twisted and compromised cecum will not correct spontaneously. Aggressive fluid therapy addresses shock but does not treat the underlying problem. Continued attempts at medical management while hoping for improvement consume precious time during which cecal viability progressively deteriorates. Any horse with clinical signs consistent with strangulating obstruction should be referred for surgical evaluation without delay, with the understanding that surgical exploration will be necessary for both diagnosis and treatment.

Surgical intervention represents the only definitive treatment for cecal torsion and must occur rapidly to offer any chance of success. Surgery is performed through a ventral midline celiotomy under general anesthesia after appropriate cardiovascular stabilization. The surgeon identifies and corrects the torsion, assessing cecal viability after repositioning. If the cecum remains viable with return of normal color and arterial pulsation, the abdomen is lavaged and closed with careful monitoring postoperatively. When the cecum has become devitalized, partial or complete typhlectomy, surgical removal of the cecum, is necessary. Complete typhlectomy requires disconnection of the ileum and anastomosis to the remaining large intestine, a technically demanding procedure. Severe adhesions or extensive necrosis may render the situation inoperable.

Supportive care during and after surgery addresses the severe systemic derangements that accompany cecal torsion. Intensive intravenous fluid therapy continues throughout the surgical and postoperative periods to maintain blood pressure and tissue perfusion. Plasma transfusion may be necessary if protein loss is severe. Antibiotic therapy targeting gram-negative organisms and anaerobes combats endotoxemia and potential peritonitis. Anti-inflammatory medications including flunixin meglumine help manage endotoxin effects. Lidocaine infusion may support cardiovascular function and gut motility. Nutritional support becomes important during prolonged recovery when enteral feeding is contraindicated. Monitoring for laminitis through hoof palpation and cryotherapy application protects against this devastating complication.

Rehabilitation following successful cecal torsion surgery requires extended time and careful management. Horses that retain their cecum require gradual reintroduction of feeding as gut function returns, typically beginning with small amounts of grass or hay and progressing slowly. Those that underwent typhlectomy face additional adaptation challenges as the gastrointestinal system learns to function without this fermentation chamber. Incision care prevents surgical site complications. Gradual return to activity follows clearance of gastrointestinal function, with hand walking beginning first and progression to turnout and eventually work over months rather than weeks. Regular veterinary reassessment guides advancement through recovery milestones.

Treatment decision factors in cecal torsion cases include the duration of signs before intervention, cardiovascular status at presentation, findings at surgery, and practical considerations including cost and intended use. Early cases with preserved cecal viability carry better prognosis than those with advanced necrosis. Horses in profound shock before surgery face significant anesthetic risk. The decision to proceed with typhlectomy versus euthanasia depends on viability of remaining intestine, the horse's overall status, and owner wishes. Financial commitment for intensive postoperative care is substantial. The prognosis remains guarded even with optimal treatment, and honest discussion of realistic outcomes helps owners make informed decisions.

Recovery timeline for horses surviving cecal torsion surgery varies based on the extent of intestinal compromise and whether typhlectomy was required. Horses that underwent simple surgical correction with cecal preservation typically require several weeks of hospitalized care followed by months of convalescence at home. The immediate postoperative period focuses on combating endotoxemia, restoring cardiovascular stability, and re-establishing gastrointestinal function. Return to enteral feeding may take several days to a week. Horses that underwent typhlectomy face longer recovery periods as their digestive system adapts to functioning without the cecum, a process that may take several months.

Post-treatment care and monitoring following cecal torsion surgery is intensive and requires specialized facilities during the initial recovery phase. Continuous monitoring of vital parameters guides fluid therapy adjustments and identifies developing complications. Serial blood work tracks inflammatory markers, organ function, and electrolyte balance. Nasogastric intubation checks for reflux indicating persistent ileus. Abdominal ultrasound may be repeated to assess for peritoneal fluid accumulation. Incision monitoring detects early signs of infection or dehiscence. Hoof care including icing and monitoring for digital pulses guards against laminitis. Once cardiovascular stability is established, attention shifts to restoring gastrointestinal function and initiating nutrition.

Prognosis factors for cecal torsion heavily influence expected outcomes. Duration of torsion before surgery represents the most critical determinant, with cases corrected within hours carrying better prognosis than those with prolonged ischemia. Degree of cecal compromise at surgery correlates with survival, as horses with viable cecum after correction fare better than those requiring typhlectomy. Pre-operative cardiovascular status affects anesthetic survival and postoperative recovery. Development of complications including peritonitis, adhesions, laminitis, or incisional problems worsens prognosis. Published survival rates for cecal torsion vary but generally range from 30 to 60 percent for horses reaching surgery, lower than many other surgical colic conditions.

Long-term soundness outlook for cecal torsion survivors depends on the presence of complications and residual effects. Horses that recovered with cecal preservation and without major complications may eventually return to previous function, though many are used for less demanding purposes than before. Those that underwent typhlectomy can survive and function but may have permanently altered digestive efficiency requiring dietary modification. Adhesion formation following abdominal surgery can cause recurring colic episodes. Laminitis occurring as a complication may result in permanent lameness. Many cecal torsion survivors are retired to light use or pasture rather than returning to athletic competition, representing a successful outcome given the severity of the initial condition.

Management practices for preventing cecal torsion focus on minimizing factors associated with cecal dysfunction and abnormal displacement. Maintaining normal gastrointestinal motility through consistent feeding schedules, adequate forage, and regular exercise supports cecal health. Avoiding abrupt dietary changes that might disrupt fermentation patterns reduces one potential trigger. Ensuring adequate water intake keeps intestinal contents appropriately hydrated. For horses with history of cecal issues, particularly careful attention to management becomes essential. Minimizing stress during transport, competition, and other disrupting events helps maintain normal gut function. While many cases of cecal torsion occur without identifiable predisposing factors, optimizing overall gastrointestinal health remains prudent.

Nutritional prevention strategies support normal cecal function and reduce impaction risk that might precede torsion. High-quality forage provided in multiple small meals rather than large twice-daily feedings mimics natural grazing behavior. Adequate long-stem fiber maintains normal gut motility patterns. Fresh, clean water available at all times prevents dehydration-related impaction. Salt supplementation encourages water consumption. Avoiding excessive grain meals that might disrupt cecal fermentation reduces risk of gas accumulation. For horses prone to digestive upset, probiotic or prebiotic supplementation may support beneficial microbial populations, though direct evidence for torsion prevention is lacking.

Exercise and conditioning considerations help maintain the gut motility that supports normal cecal function. Regular physical activity promotes intestinal movement and reduces stasis. Horses confined to stalls for medical reasons should receive hand walking when possible to stimulate gut function. Avoiding exercise on a full stomach reduces the risk of displacement when a heavy cecum combines with physical activity. Gradual return to work following layoff periods prevents the digestive disruption that can accompany sudden training changes. Maintaining appropriate body condition through balanced exercise and nutrition supports overall metabolic health.

Environmental factors particularly relevant to cecal torsion prevention include careful management during high-risk periods. Broodmares should be monitored closely during late gestation and the early postpartum period, with prompt veterinary attention for any signs of colic. Horses recovering from general anesthesia require vigilant observation for the first 72 hours, with immediate attention to any colic signs. Hospitalized horses benefit from proactive gut motility support and regular assessment. Housing should allow natural movement and social interaction that reduce stress. During transport, frequent water offerings and minimizing transit time help maintain gut function.

Vaccination and deworming protocols do not directly prevent cecal torsion but support the overall gastrointestinal health that reduces risk for various colic conditions. Appropriate parasite control prevents damage to intestinal walls that could compromise function. Avoiding excessive or inappropriate anthelmintic use protects beneficial gut microorganisms. Vaccination against diseases that cause systemic illness reduces secondary effects on gastrointestinal motility. When horses require medical treatment that might affect gut function, particularly NSAIDs or antibiotics, monitoring for digestive side effects allows early intervention. Collaboration with a veterinarian to develop individualized health protocols helps minimize colic risk while addressing each horse's specific needs.

Daily management adjustments for horses at elevated cecal torsion risk or those recovered from surgery emphasize consistent routine and digestive support. Feeding practices should provide forage in multiple small meals throughout the day, reducing large cecal volume fluctuations. Water intake monitoring ensures adequate hydration. Daily observation of appetite, water consumption, and fecal output allows early detection of developing problems. Horses with history of cecal issues benefit from particularly attentive observation, with owners trained to recognize subtle early colic signs. Minimizing unnecessary management changes reduces stress-related digestive disturbances. Maintaining detailed records helps identify patterns that might indicate increased risk.

Housing and turnout considerations for at-risk horses balance movement benefits against monitoring needs. Maximum turnout time consistent with safety allows natural movement that supports gut function. Social housing with compatible companions reduces stress. Broodmares in late pregnancy may benefit from housing arrangements that allow close observation while maintaining movement opportunities. Horses recovering from cecal surgery require carefully controlled reintroduction to turnout, beginning with small areas and limited time before gradual expansion. Paddock and pasture surfaces should be free of hazards that might cause injury requiring stall confinement.

Exercise modifications depend on the individual horse's history and current status. Horses without prior cecal issues but at elevated risk due to management circumstances benefit from regular, consistent exercise that maintains gut motility. Avoiding intense work immediately after feeding reduces potential for displacement. Post-surgical horses require extended controlled exercise programs with veterinary guidance on advancement timing. Return to work following cecal surgery proceeds more slowly than for many other conditions, with months of gradual progression before resuming previous activity levels. Some cecal torsion survivors may be appropriate only for light use permanently.

Monitoring and ongoing care for horses with cecal torsion history requires heightened vigilance from owners and regular veterinary input. Any sign of colic, however mild, warrants prompt evaluation given the known predisposition to serious cecal conditions. Periodic veterinary examinations allow assessment of overall condition and provide opportunity to discuss any concerns. Owners should maintain emergency contact information and have transportation arrangements in place should urgent referral become necessary. Understanding that prior cecal problems increase risk for recurrence enables appropriate preparedness.

Quality of life and use considerations for cecal torsion survivors acknowledge both the severity of the condition and the potential for meaningful recovery. Many horses surviving cecal torsion enjoy comfortable lives with appropriate management, even if their previous athletic career cannot continue. Horses that underwent typhlectomy can adapt to functioning without a cecum but may require ongoing dietary attention. The goal of management becomes maintaining comfort and preventing recurrence rather than maximizing performance. For horses experiencing recurrent colic episodes despite optimal management, quality of life discussions with veterinary input help guide decisions about continued management versus humane euthanasia.

High-risk breeds for cecal torsion cannot be definitively identified because this condition does not demonstrate clear breed predisposition. Any horse of any breed can develop cecal torsion given appropriate predisposing circumstances. However, certain breed-related management patterns may influence population-level risk. Large warmblood sport horses frequently undergoing orthopedic surgery with general anesthesia face elevated post-anesthetic colic risk. Thoroughbred and warmblood broodmares may be overrepresented due to breeding-related risk factors. Draft breeds with large gastrointestinal capacity may develop more significant gas distension when motility is compromised. Arabian horses and other breeds with sensitive digestive systems might experience more pronounced responses to stress and dietary changes.

Use and discipline considerations affect cecal torsion risk across all breeds. Horses in breeding programs, particularly broodmares, face elevated risk during the periparturient period. Performance horses undergoing frequent surgical procedures for injuries accumulate anesthetic events that increase cumulative post-operative colic risk. Horses in disciplines requiring travel and competition stress experience digestive challenges that may predispose to dysfunction. Conversely, horses in consistent work programs with stable management may have lower risk than those experiencing frequent changes. No discipline appears specifically associated with increased cecal torsion risk when management factors are controlled.

Genetic testing and breeding recommendations are not applicable to cecal torsion as this condition lacks hereditary basis. However, breeders should be aware of the elevated risk broodmares face during late pregnancy and early postpartum. Selecting for overall robust constitution and calm temperament may indirectly reduce colic risk by producing horses that handle management changes and stress well. Mares with history of periparturient colic complications may warrant particularly careful monitoring during subsequent pregnancies. Individual horses with personal history of cecal problems should be managed carefully regardless of breed, with owners and veterinarians aware of their elevated risk for recurrence or related conditions.

Commonly co-occurring conditions with cecal torsion reflect both predisposing factors and complications of this severe abdominal crisis. Pre-existing cecal impaction may precede torsion in some cases, with the enlarged, heavy cecum becoming prone to displacement. Post-anesthetic ileus frequently accompanies the immediate post-surgical period when cecal torsion occurs. Endotoxemia develops rapidly as intestinal barrier function fails, triggering systemic inflammatory response. Laminitis represents a devastating complication occurring in some survivors, caused by endotoxin-mediated damage to hoof laminar tissues. Adhesion formation following abdominal surgery can cause chronic or recurrent colic. Peritonitis may develop if cecal rupture occurs or if bacterial contamination happens during surgery.

Conditions with similar symptoms requiring differentiation from cecal torsion include other causes of severe acute colic. Large colon volvulus produces comparable clinical signs and requires the same surgical urgency. Small intestinal strangulation presents with more prominent nasogastric reflux but similar cardiovascular compromise. Ruptured stomach or intestine causes acute shock but affected horses often show initial relief as intraluminal pressure releases. Severe colitis can produce endotoxemic shock mimicking surgical colic. Uterine torsion in late-pregnancy mares presents with abdominal pain requiring differentiation. The specific diagnosis often becomes clear only at surgical exploration, emphasizing that decisions to operate should be based on emergency presentation rather than precise diagnosis.

Potential complications of cecal torsion extend throughout the treatment and recovery periods. Cecal rupture before or during surgery results in fatal peritonitis. Cardiovascular collapse during anesthesia induction reflects the severity of pre-operative shock. Anastomotic failure following typhlectomy causes fatal peritonitis. Incisional complications including infection, dehiscence, and hernia formation occur in some surgical survivors. Protein-losing enteropathy develops from severe intestinal damage. Chronic ileus or motility dysfunction can persist after recovery. Jugular thrombophlebitis may result from prolonged intravenous catheterization. The high complication rate underscores the serious nature of cecal torsion and the guarded prognosis even with optimal treatment.
