Preservation of the inferior mesenteric artery VS ligation of the inferior mesenteric artery in left colectomy: evaluation of functional outcomes —a prospective non-randomized controlled trial

AbstractVascular approach during elective laparoscopic left colectomy impacts post-operative outcomes. The aim of our study was to evaluate how different approaches impact positively defecatory, urinary and sexual functions and quality of life during elective laparoscopic left colectomy. A prospective non-randomized controlled trial at two tertiary center was conducted. All patients who underwent elective laparoscopic left colonic resection from January 2019 to July 2022 were analyzed. They were divided into two groups based on Inferior Mesenteric Artery (IMA) preservation with distal ligation of sigmoid branches close to a colonic wall for complicated diverticular disease and IMA high tie ligation for oncological disease. Patients were asked to fulfil standardized, validated questionnaires to evaluate pre and post-operative defecatory, urinary and sexual functions and quality of life. Defecatory disorders were assessed by high-resolution anorectal manometry preoperatively and six months after surgery. A total of 122 patients were included in the study. The 62 patients with IMA preservation showed a lower incidence of defecatory disorders also confirmed by manometer data, minor incontinence and less lifestyle alteration than the 60 patients with IMA high tie ligation. No urinary disorders such as incomplete emptying, frequency, intermittence or urgency were highlighted after surgery in the IMA preservation group. Evidence of any sexual disorders remained controversial. The IM...
