A CASE OF MESENTERIC PANNICULITIS AFTER ENDOSCOPIC POLYPECTOMY FOR SIGMOID COLON POLYP ON A LONG STALK

Abstract

A case of mesenteric panniculitis after colonoscopic polypectomy is reported. The patient was a 39-year-old female, complaining of abdominal pain after polypectomy for sigmoid colon polyp on a long stalk. Abdominal CT showed increased density of the pericolonic fat tissue closed to the clip, which was used after colonoscopic polypectomy. Endoscopic examination revealed edematous mucosa in sigmoid colon. She was diagnosed as having mesenteric panniculitis from these findings, which was considered to be induced by colonic polypectomy or clipping. Physicians would pay care for hemorrhage, but not for the other complications, e.g. perforation and mesenteric panniculitis, when polypectomy for polyp on a long stalk is performed, because major of complications associated with polypectomy for such a polyp is bleeding. Such a case, mesenteric panniculitis after colonic polypectomy for polyp on a long stalk, is rare and has not been reported from Japan. Since unexpected complications could occur, careful follow-up would be wise after endoscopic polypectomy.
