Different surgical approach are used to perform colorectal resection and there is not a standardized technique. For the same concerns, studies have addressed the mesenteric vascular and nerve preservation both in oncological and benign intestinal disease with improved functional outcome. Therefore, the aim of this prospective study is to analyze feasibility and safety of mesenteric vascular and nerve Sparing Surgery in laparoscopic segmental colorectal resection for DIE with short and long term follow up. Women with DIE ,that underwent laparoscopic segmental colorectal resection, will undergo resection performed with inferior mesenteric artery and branching arteries preservation by dissecting adherent to the intestinal wall with mesenteric vascularization and innervation entirely preserved. Personal history, clinical data, surgical data, short and long term surgical complications and long term outcomes will be recorded. Symptoms and bowel function will be evaluated before and after surgery.
