The effect of vascular anatomy and gender on bowel function after right colectomy with extended D 3-mesenterectomy THORSEN

Background: Extended D3-mesenterectomy for right-sided colon cancer, removes all tissue around the superior mesenteric vessels beneath pancreas leading to transection of superior mesenteric plexus. In a previous study, the denervation was associated with 0.48 more stools/day. The study aims are to examine how presence of arterial branches proximal to the dissection area, gender and prolonged observation time after surgery affect bowel function following denervation. Methods: The study compares bowel function and Quality of Life in two groups undergoing right colectomy with extended D3-mesenterectomy and traditional D2-mesenterectomy. For further comparison, the denervated group was divided into groups with and without arterial branches arising proximal to the denervation. Instruments used were Gastrointestinal Quality of Life Index (0–144; 144= best) (GIQLI), Diarrhea Assessment Scale (0–12; 0= best) (DAS) and 3 additional questions (Ability to postpone defecation, night defecation, degree of distress). A second interview with prolonged observation time was performed for patients with abnormal bowel habits, defined as [...] THORSEN, Yngve, et al.
