The causes having high mortality rates were acute mesenteric ischaemia and ileosigmoid knotting (75% in each pathology).
The rate of bowel gangrene has been reported to be 93-100% in ileosigmoid knotting.
Ileosigmoid knotting and acute mesenteric ischaemia have to be taken care of as these causes are difficult to diagnose early and are having high mortality rates.
Ninety-two cases of ileosigmoid knotting
7) Some rare causes have also been reported which include Schistosomiasis, (15) torsion of appendix epiploicae, (16) pregnancy, (17) ileosigmoid knotting
, (18) Meckel's diverticulum enterolith, (19) or even an intramural hematoma due to anticoagulant therapy.
Objective: Ileosigmoid knotting (ISK), in which the ileum wraps around the base of the sigmoid colon, is a rare cause of intestinal obstruction.
Ileosigmoid knotting in the elderly: Outcomes of 32 cases over 44.
Ileosigmoid knotting (ISK) is a rare cause of intestinal obstruction in which the ileum wraps around the base of the sigmoid colon and forms a pseudoknot.
7 Although the incidence of ileosigmoid knotting (ISK) is not well known, it generally occurs in areas with a high incidence of sigmoid volvulus, and ISK accounts for 5%-50% of sigmoid volvulus cases.
The factors involved in causing ileosigmoid knotting are freely mobile small bowel with long mesentery; long sigmoid colon with a narrow pedicle; ingestion of high bulk diet in presence of empty small bowel; late pregnancy; transmesenteric herniation; Meckel's diverticulitis with a band; ileocaecal intussusceptions and floating caecum [1, 5, 7-11].
