Introduction: The ileosigmoid node is a double volvulus involving the sigmoid and the small intestine. The preoperative diagnosis is difficult in our practice setting. We report a case of ileosigmoid node that we discuss with data from the literature. Observation: This was a 40-year-old man admitted for diffuse abdominal pain of progressive onset, paroxysmal, accompanied by cessation of materials and gas, profuse vomiting of food and hiccups, progressing for 24 hours. With a history of persistent constipation and episodes of sub-occlusion, clinical examination noted pain, abdominal distension and dullness of the flanks and inaudible peristalsis. The digital rectal examination noted an emptiness of the rectal bulb and a bulging of the Douglas. The biological assessment was unremarkable. The ASP showed an arched image. Confirmation was intraoperative with a small bowel volvulus around the sigmoid in the form of a node producing double ileal and sigmoid necrosis. We performed an ileo-ileal anastomosis resection and a left iliac colostomy using the Hartman technique. The postoperative follow-up was simple, the patient was discharged on D10 postoperative. Six weeks later the patient was readmitted for restoration of colonic continuity. Five months later, no complaints were reported. Conclusion: The ileo-sigmoid node is a rare cause of intestinal obstruction, difficult to diagnose preoperatively in our exercise setting, the progression is rapid towards digestive necrosis. The availability of emergency CT examinations and early management of this condition would improve the prognosis.
