Abstract
Ileosigmoid knotting (ISK) is an extremely rare double-loop bowel obstruction. ISK is treated by emergency surgery with a relatively poor prognosis. Although some classification methods have been developed for ISK to date, the most comprehensive method was defined in 2018. Then, some subjects concerning this issue were evaluated in the literature. The aim of this paper is to update the last classification method in light of both the evaluations in the literature and our clinical experience with 80 ISK cases, which is one of the largest published single-centre ISK series.
Highlights
Ileosigmoid knotting (ISK), the wrapping of the ileum or sigmoid colon around the base of the other structure causing a double-loop intestinal obstruction, was first described by Rokitansky in 1836.1 ISK is an extremely rare disease with a few hundreds cases reported to date.[2]
I directly correlated the presence of bowel gangrene and poor American Society of Anesthesiologists (ASA) score with the management as well as the prognosis in my algorithm
Life expectancy, which is generally higher in developed countries, varies from a country to another one
Summary
Ileosigmoid knotting (ISK), the wrapping of the ileum or sigmoid colon around the base of the other structure causing a double-loop intestinal obstruction, was first described by Rokitansky in 1836.1 ISK is an extremely rare disease with a few hundreds cases reported to date.[2] Many different classifications including prevalence (sporadic or endemic), active component (ileum or sigmoid colon), volvulus direction (counterclockwise or clockwise), and volvulus degree (360) have been published in literature..
