A 68-year-old retired university librarian navigating uncomplicated sigmoid volvulus followed by definitive surgery
Elena developed sudden progressive abdominal distension, cramping, nausea, and inability to pass stool or gas after several days of worsening constipation.
CT showed a markedly dilated sigmoid loop with a mesenteric whirl and tapering transition, without free air, peritonitis, or clear bowel-wall necrosis.
Urgent flexible endoscopy confirmed viable mucosa, successfully detorsed the sigmoid colon, and allowed placement of a rectal decompression tube.
Because recurrence after detorsion alone is common, her journey continued to bowel preparation and definitive sigmoid colectomy during the same hospital admission.
The scope untwisted the colon and relieved the pressure, but the operation prevented the same long redundant segment from twisting again.
Elena initially thought the swelling represented another severe constipation episode.
The abdomen continued to enlarge while gas and bowel movements stopped completely.
Her long history of constipation and a redundant sigmoid colon created the anatomy for twisting around the mesenteric axis.
The absence of peritonitis or ischemic CT findings allowed an endoscopic first step rather than immediate emergency resection.
The turning point came when Elena understood why the twisted segment and bowel viability determined treatment.
Elena felt dramatically better after the endoscope untwisted the bowel and released trapped gas.
The colorectal team explained that the same redundant sigmoid segment remained capable of twisting again.
A decompression tube maintained reduction and supported preparation for surgery.
The team reviewed elective resection during the same admission while the bowel was viable and the patient was medically optimized.
Elena chose definitive sigmoid colectomy rather than accepting a high risk of another emergency obstruction.
The follow-up plan needed to explain the volvulus type, treatment performed, recurrence risk, remaining-colon health, bowel function, and emergency warning signs.
The twist location, mesenteric whirl, transition points, bowel-wall enhancement, free air, fluid, and competing obstruction causes were assessed.
The endoscopist examined the twisted segment for dusky, ulcerated, necrotic, or perforated mucosa while attempting detorsion.
The redundant sigmoid segment was removed during the same admission before another volvulus occurred.
A bowel plan was developed, while sudden distension, vomiting, or inability to pass gas remained emergency warning signs.
After hospital stabilization, GastroDoxs can review CT findings, detorsion, rectal-tube use, colectomy, pathology, stoma care, constipation, remaining-colon symptoms, and recurrence prevention.
The pathway moved from distension and obstipation to CT localization, viability assessment, segment-specific emergency treatment, recovery, and recurrence prevention.
Elena initially thought the swelling represented another severe constipation episode.
Review abdominal distension →CT showed a markedly dilated sigmoid loop with a mesenteric whirl and tapering transition, without free air, peritonitis, or clear bowel-wall necrosis.
Review colonic volvulus →Endoscopic detorsion is not the appropriate first step when peritonitis, perforation, gangrene, or severe clinical instability is present.
Compare bowel obstruction →The tube helped maintain reduction, vent gas, and support bowel preparation after successful detorsion.
Schedule follow-up →The pathway depends on the twisted colon segment, clinical stability, bowel viability, peritonitis or perforation, endoscopic success, operative risk, and recurrence history.
The twist location, mesenteric whirl, transition points, bowel-wall enhancement, free air, fluid, and competing obstruction causes were assessed.
Tenderness, lactate, bowel-wall enhancement, pneumatosis, free air, bleeding, shock, and endoscopic appearance determine urgency.
Flexible sigmoidoscopy or colonoscopy allows direct assessment of mucosal viability and controlled decompression.

A bowel plan was developed, while sudden distension, vomiting, or inability to pass gas remained emergency warning signs.
Severe worsening pain, a rigid abdomen, fever, vomiting, fainting, confusion, blood in stool, or rapidly increasing distension requires immediate emergency care.
The colon segment, twist anatomy, bowel viability, clinical stability, recurrence history, operative risk, pathology, and response to treatment are interpreted together.
The sigmoid colon twists around its mesentery, obstructing the lumen and potentially compromising venous and arterial blood flow.
A whirl sign, transition or bird-beak configuration, severe sigmoid dilation, bowel-wall changes, free air, and alternative causes guide treatment.
Flexible sigmoidoscopy or colonoscopy allows direct assessment of mucosal viability and controlled decompression.
The redundant sigmoid remains in place, so definitive resection is generally recommended during the index admission when feasible.
Endoscopic detorsion is not the appropriate first step when peritonitis, perforation, gangrene, or severe clinical instability is present.
The visit connected emergency imaging, detorsion or surgery, pathology, bowel recovery, constipation, stoma needs, and recurrence prevention.
The team evaluated pain, distension, vomiting, vital signs, hydration, tenderness, guarding, lactate, and possible sepsis.
The twist location, mesenteric whirl, transition points, bowel-wall enhancement, free air, fluid, and competing obstruction causes were assessed.
The endoscopist examined the twisted segment for dusky, ulcerated, necrotic, or perforated mucosa while attempting detorsion.
A decompression tube was placed after reduction, and the team monitored stool, gas, abdominal size, and early retorsion.
The patient reviewed sigmoid colectomy, anastomosis, possible stoma, operative risk, and the consequences of declining definitive treatment.
Treatment restored bowel passage, removed nonviable or recurrence-prone colon when necessary, and created a clear recovery and emergency plan.
IV fluids, electrolyte correction, bowel rest, nasogastric decompression when needed, and surgical consultation began immediately.
The sigmoid twist was traversed carefully, the colon decompressed, and viable mucosa confirmed.
The tube helped maintain reduction, vent gas, and support bowel preparation after successful detorsion.
The redundant sigmoid segment was removed during the same admission before another volvulus occurred.
Hydration, pain control, mobility, diet advancement, wound care, and monitoring for ileus or anastomotic complications supported recovery.

A bowel plan was developed, while sudden distension, vomiting, or inability to pass gas remained emergency warning signs.
The correct pathway depends on whether the volvulus is sigmoid, cecal, transverse, or another rare type, and whether the bowel remains viable.
Urgently untwist and decompress stable uncomplicated sigmoid volvulus while assessing mucosal viability.
Best for: Sigmoid volvulus without peritonitis, perforation, gangrene, or severe instability
Limitations: Failure, perforation, early retorsion, and high long-term recurrence remain possible
Takeaway: Use as emergency relief followed by definitive surgical planning
Remove the redundant sigmoid after successful detorsion while the patient and bowel are optimized.
Best for: Patients who can tolerate definitive surgery after uncomplicated reduction
Limitations: Operative and anastomotic risks remain
Takeaway: This is the standard recurrence-prevention pathway after successful detorsion
Remove cecal or transverse volvulus, failed sigmoid detorsion, or ischemic, perforated, or gangrenous bowel.
Best for: Cecal and most transverse volvulus, peritonitis, perforation, ischemia, shock, or failed endoscopy
Limitations: May require a stoma and carries greater risk during sepsis or necrosis
Takeaway: Bowel viability and segment type override attempts to avoid surgery
Consider fixation or percutaneous endoscopic colostomy only in carefully chosen patients who cannot undergo standard resection.
Best for: Highly selected viable bowel or prohibitive surgical-risk situations
Limitations: Recurrence, infection, leakage, device complications, and weaker evidence
Takeaway: These approaches do not replace standard colectomy for typical candidates
A twisted colon can progress from obstruction to ischemia, gangrene, perforation, peritonitis, sepsis, and shock.
How the uncomplicated sigmoid volvulus followed by definitive surgery journey changed bowel function, recurrence risk, and emergency awareness
The sigmoid twist was traversed carefully, the colon decompressed, and viable mucosa confirmed.
The redundant sigmoid segment was removed during the same admission before another volvulus occurred.
Hydration, pain control, mobility, diet advancement, wound care, and monitoring for ileus or anastomotic complications supported recovery.
Elena returned to daily responsibilities with a written bowel, wound or stoma, hydration, medication, and emergency plan.
The patient understood that a new obstruction pattern still requires urgent imaging even after definitive treatment.
The scope untwisted the colon and relieved the pressure, but the operation prevented the same long redundant segment from twisting again.
This global patient journey is an educational composite illustrating uncomplicated sigmoid volvulus treated with urgent flexible endoscopic detorsion, rectal-tube decompression, and same-admission sigmoid colectomy. It does not represent a specific patient. Colonic volvulus type, bowel viability, detorsion success, operation, anastomosis or stoma need, complications, recurrence, and recovery vary. The local office information is for stable planned follow-up and does not mean emergency detorsion, colectomy, intensive care, or stoma surgery occurs in the office. Rapid distension, severe pain, vomiting, fever, fainting, confusion, blood in stool, or inability to pass gas requires immediate hospital assessment.
Answers about uncomplicated sigmoid volvulus followed by definitive surgery, CT findings, detorsion, colectomy, recurrence, recovery, and emergency warning signs
It is twisting of a colon segment around its mesentery, producing obstruction and potentially cutting off blood supply.
The sigmoid colon is most common, followed by the cecum. Transverse and splenic-flexure volvulus are rare.
Common symptoms include rapid abdominal distension, cramping or pain, constipation, inability to pass gas, nausea, and vomiting.
Abdominal imaging, usually CT, shows the twisted obstructed segment and assesses ischemia or perforation.
Stable uncomplicated cases can often be detorsed endoscopically, but definitive sigmoid resection is usually advised because recurrence is common.
It can maintain decompression, vent gas, and help reduce early retorsion after successful endoscopic detorsion.
The redundant twisted segment remains after endoscopic treatment and can recur quickly or later.
Endoscopic reduction is generally not recommended because success is low and perforation or missed ischemia is a concern.
Peritonitis, perforation, gangrene, ischemia, shock, failed detorsion, or cecal and most transverse volvulus generally requires surgery.
Recurrence at the resected segment is uncommon, but another bowel segment can rarely twist if additional anatomic or motility risk exists.
