The rectosigmoid colon is the most common location for bowel endometriosis, followed by the rectum, ileum, appendix, and cecum (4,8) (figures 3, 4, and 5, pages 38-39).
BBPS (7) is a 4-point scoring system, from 0 (inadequate) to 3 (excellent), applied to the three parts of the colon broad regions: the right colon, transverse colon, and rectosigmoid colon.
Ingested foreign bodies have a propensity to lodge in regions of anatomic angulation, including the duodenal C- loop, the ligament of Treitz, the ileocecal and rectosigmoid junctions, or in acquired strictures.
Endoscopic biopsy diagnosis of acute gastrointestinal graft-versus-host disease: rectosigmoid biopsies are more sensitive than upper gastrointestinal biopsies.
Only 1% of these penetrate the gastrointestinal tract (1, 2).Common perforation sites are crycopharyngeal ring, cardia, phylorus, C-loop duodenum, ligament of Treitz, Meckel diverticulum, ileocecal valve, appendix, and rectosigmoid junction (1-3).
The cecal pole was reached; unremarkable mucosa from the cecum/ileocecal valve down to the rectosigmoid colon save for few, diminutive polyps seen over the rectum/distal sigmoid, removed by cold biopsy forceps.
Colonoscopy was performed; the findings demonstrated that the anus was normal, whereas there were decreased vascular markings with multiple erosions and fragility in the rectosigmoid. Biopsies were taken from the rectal mucosa, and the findings showed that there were multiple erosions and fragility in the mucosa of the descending colon.
