Given that endoscopic detorsion will likely be unsuccessful due to the double-loop knot and is hazardous given the possibility of missing ileal gangrene, endoscopic decompression is generally not attempted in ISK.
In addition to diagnostic evaluations, colonoscopy enables therapeutic procedures such as biopsy, polypectomy, endoscopic mucosal resection, volvulus detorsion, bleeding control, dilatation of strictures, and endoluminal stent applications (6).
Of the 66 patients, 1 patient was treated with rehydration therapy; 51 patients underwent only endoscopic interventions, such as flexible endoscopic detorsion or endoscopic placement of a sliding tube; 5 patients underwent endoscopic detorsion and subsequent sigmoidectomy; and 9 patients received a sigmoidectomy without endoscopic interventions.

The American Society of Colon and Rectal Surgeons suggest initial rigid or flexible endoscopy to assess for intestinal viability and to effect therapeutic detorsion and decompression (Grade 1c) [11]; this is reported to be successful in 75-95% of cases [11-13].
In the past, salpingo-oophorectomy without prior detorsion was the traditional mode of treatment, due to the fear of thromboembolism.
