“…There have been cases reported on ileoileal knots, 1 appendico‐ileal knots 2 and over 260 cases of ileosigmoid knots since 1845, 3–6 but, to our knowledge, no previous case of an ileocaecal knot has been reported.…”

“…Nonetheless, it is important that they should at least raise the suspicion of ISK. The findings in a CT scan suggestive of ISK include the whirl sign created by the twisted intestine and sigmoid mesocolon in ileosigmoid knot, medial deviation of the cecum, and descending colon 111314. In addition, others have noted radial distribution of the intestine and mesenteric vasculature and consider it to be helpful diagnostic information 11.…”

Ileosigmoid knotting, also known as compound volvulus or double volvulus, is a rare cause of intestinal obstruction. In this condition the ileum wraps around the base of the sigmoid colon and forms a knot. Ileosigmoid knotting is an unusual entity in the West, but is comparatively common in certain African, Asian and Middle Eastern nations. The condition is serious, generally progressing rapidly to gangrene. Awareness of the condition is essential for prompt diagnosis and optimal management. This report describes a case in a 60-year-old male and describes the management of this rare condition. An additional 280 recent cases in the English literature are reviewed as to etiopathogenesis, presentation, diagnostic modalities, surgical interventions and outcome.

“…The cecum is also pulled medially due to the stretching of the terminal ileum. 2,8,14 ISK is a surgical emergency and warrants an exploratory laparotomy. Unwinding of the knot may be attempted in cases of retained vascular supply and viable bowel loops.…”

Ileosigmoid knot (ISK) is an unusual and serious condition that is known to pose a diagnostic dilemma due to overlapping features of acute closed-loop intestinal obstruction. Early diagnosis and intervention are of immense importance in this condition because they can prove life threatening with rapid progression to gangrene of both the ileum and sigmoid colon. We report a case of a 27-year-old man who presented 2 days post-appendicectomy procedure with acute abdominal pain, abdominal distention, and hypovolemic shock. Initial evaluation with ultrasonography (USG) and abdominal X-ray was performed, which revealed pleural effusion, ascites, and an ahaustral dilated large bowel loop in the right upper abdomen with convergence in the left lower abdomen. Further imaging with computed tomography revealed closed-loop obstruction of the sigmoid colon with beaked appearance of its afferent and efferent limbs in the pelvis. There was associated whirling or knotting of the ileum around the sigmoid pedicle along with features of mesenteric ischemia. Emergency laparotomy was performed, which revealed ISK with gangrene of the ileal and large bowel loops.
