Representative histologic sections of the anastomotic sites of the study and control groups, one month after surgery (H&E & Masson’s, 40x). (A,B) MCT-A group: the mucosal layer was continuous with a relatively smooth surface and less collagen content in the muscular layer. (C,D) MCT-B group: Mucosal, submucosal and muscular with good continuity. (E,F) Hand-sewn group: mucosal continuity was slightly worse, the mucosal layer was continuous with presence of silk-related foreign body granulomas and mild inflammatory infiltration in the muscular and serous layer along with dense collagen deposition.
