Causes & Risk Factors
Several factors can contribute to Colonic Volvulus.
The underlying cause of colonic volvulus involves both anatomical factors and triggering events that allow a section of colon to twist.
The underlying cause of colonic volvulus involves both anatomical factors and triggering events that allow a section of colon to twist. In sigmoid volvulus, the most common type, an abnormally long and mobile sigmoid colon combined with a narrow base where it attaches creates the perfect setup for twisting. This anatomical arrangement often develops over years of chronic constipation, which causes the colon to elongate and become more mobile than normal.
Cecal volvulus typically occurs when the cecum and ascending colon fail to properly attach to the back wall of the abdomen during fetal development.
Cecal volvulus typically occurs when the cecum and ascending colon fail to properly attach to the back wall of the abdomen during fetal development. This leaves these sections more mobile than they should be, allowing them to flip or twist under certain circumstances. Previous abdominal surgeries can also create adhesions that change normal anatomy and increase twisting risk.
Several factors can trigger the actual twisting event.
Several factors can trigger the actual twisting event. Sudden increases in abdominal pressure from heavy lifting, coughing fits, or straining during bowel movements can cause a mobile colon segment to rotate. High-fiber meals, certain medications that slow gut movement, or even changes in body position during sleep have been reported as potential triggers. In some cases, the twisting happens without any obvious precipitating event, particularly in people with the predisposing anatomical factors.
Risk Factors
- Chronic constipation over many years
- Age over 60 years
- Previous abdominal or pelvic surgery
- High-fiber diet in susceptible individuals
- Chronic use of laxatives or stool softeners
- Neurological conditions affecting bowel function
- Psychiatric medications that slow gut movement
- Male gender
- Living in certain geographic regions
- History of previous volvulus episodes
Diagnosis
How healthcare professionals diagnose Colonic Volvulus:
- 1
When someone arrives at the emergency room with symptoms suggesting colonic volvulus, doctors typically start with a physical examination focusing on the abdomen.
When someone arrives at the emergency room with symptoms suggesting colonic volvulus, doctors typically start with a physical examination focusing on the abdomen. They'll look for distension, listen for absent or abnormal bowel sounds, and check for areas of tenderness. The abdomen often appears visibly swollen and may feel tight to the touch.

Imaging studies provide the definitive diagnosis.
Imaging studies provide the definitive diagnosis. A CT scan of the abdomen is usually the first choice, as it can quickly identify the twisted colon and show the characteristic "whirl sign" - a spiral pattern created by the twisted intestine and its blood vessels. Plain X-rays may show a dramatically enlarged colon with a distinctive "coffee bean" or "bent inner tube" appearance in sigmoid volvulus cases. For cecal volvulus, X-rays might reveal an abnormally positioned, gas-filled structure in an unusual location.

In some cases, doctors may perform a contrast enema study, where contrast material is introduced through the rectum to outline the colon's shape.
In some cases, doctors may perform a contrast enema study, where contrast material is introduced through the rectum to outline the colon's shape. This can show the exact location where the intestine becomes obstructed and twisted. Blood tests help assess for signs of infection, dehydration, or tissue death. If complications have developed, lab values may show elevated white blood cell counts, electrolyte imbalances, or markers suggesting intestinal tissue damage.
Complications
- The most serious complication of colonic volvulus occurs when the twisted intestine loses its blood supply, a condition called ischemia or strangulation.
- This typically happens within 12-24 hours if the volvulus isn't corrected, though timing can vary.
- When intestinal tissue dies from lack of blood flow, it can perforate, spilling bacteria and waste into the normally sterile abdominal cavity and causing life-threatening peritonitis.
- Other complications include severe electrolyte imbalances from prolonged vomiting and inability to absorb fluids normally.
- Aspiration pneumonia can develop if repeated vomiting leads to inhaling stomach contents into the lungs.
- Even after successful treatment, some people experience ongoing bowel function changes, particularly if surgery was required or if there was any period of compromised blood flow to the intestine.
- The mortality rate for colonic volvulus ranges from 10-20% overall but can be much higher when diagnosis is delayed or complications have already developed.
Prevention
- Preventing colonic volvulus focuses primarily on managing the risk factors that contribute to its development.
- The most effective preventive measure involves maintaining regular, healthy bowel habits to prevent chronic constipation.
- This includes eating adequate fiber, staying well-hydrated, and getting regular physical activity.
- However, people with a history of volvulus should work with their doctors to find the right balance, as too much fiber too quickly can sometimes trigger episodes in susceptible individuals.
- For people who've had one episode of sigmoid volvulus successfully treated with nonsurgical decompression, elective surgery to remove the redundant colon section prevents recurrence in over 90% of cases.
- This planned surgical approach is much safer than waiting for emergency situations to develop.
- Regular follow-up with gastroenterologists helps ensure that bowel habits remain optimal and any warning signs get addressed promptly.
- While some risk factors like age, gender, and anatomical variations can't be changed, managing conditions that affect intestinal motility can help reduce risk.
- This includes careful medication management for people taking drugs that slow gut function and appropriate treatment of neurological conditions that affect bowel control.
Treatment for colonic volvulus depends on the location of the twist, how long it's been present, and whether complications have developed.
Treatment for colonic volvulus depends on the location of the twist, how long it's been present, and whether complications have developed. For sigmoid volvulus, doctors often first attempt nonsurgical decompression using a flexible sigmoidoscope or colonoscope. During this procedure, they insert a flexible tube through the rectum to untwist the colon and release trapped gas and stool. Success rates for this approach reach 70-80% when performed promptly, though the volvulus tends to recur without additional treatment.
When nonsurgical decompression succeeds, doctors typically recommend elective surgery within days to weeks to prevent recurrence.
When nonsurgical decompression succeeds, doctors typically recommend elective surgery within days to weeks to prevent recurrence. The standard surgical approach involves removing the redundant, mobile section of sigmoid colon and reconnecting the healthy ends. For cecal volvulus, surgical intervention is usually needed immediately since nonsurgical decompression rarely works for this location.
Surgical options include detorsion (untwisting) combined with cecopexy (anchoring the cecum to the abdominal wall) or cecectomy (removing the affected section).
Surgical options include detorsion (untwisting) combined with cecopexy (anchoring the cecum to the abdominal wall) or cecectomy (removing the affected section). If the twisted intestine has lost its blood supply and died, emergency surgery becomes necessary to remove the damaged tissue and create either an immediate reconnection or temporary colostomy. Laparoscopic techniques are increasingly used when possible, offering smaller incisions and faster recovery times.
Recent advances in surgical techniques include improved methods for determining intestinal viability during surgery and better approaches for minimally invasive repair.

Some centers are exploring endoscopic techniques for preventing recurrence, though surgery remains the gold standard for definitive treatment.
Living With Colonic Volvulus
People who've experienced colonic volvulus need to develop a heightened awareness of their bowel habits and digestive symptoms. This means paying attention to changes in bowel movement frequency, consistency, or ease of passage. Many find it helpful to keep a simple diary tracking bowel movements, dietary intake, and any abdominal symptoms to share with their healthcare providers during follow-up visits.
