Mesentery-Preserving Hand-Sewn Anastomosis for Rectal Endometriosis: A Nerve-Sparing Laparoscopic Technique

This single-center retrospective cohort study evaluated a mesentery-preserving, nerve-sparing laparoscopic surgical technique for women undergoing bowel resection for rectal endometriosis, using a full-thickness anterior lesion excision and mesorectum-preserving limited posterior resection with a hand-sewn anastomosis. The paper compares this approach with conventional stapled resection, with main outcomes including anastomotic integrity and functional outcomes at 12 months. The key finding is that the method can safely preserve neurovascular structures, with initial proof-of-concept data demonstrating surgical feasibility. The authors frame the results as hypothesis-generating and note feasibility rather than definitive comparative efficacy. This paper is centrally about endometriosis — it focuses specifically on a nerve-sparing laparoscopic technique for rectal endometriosis.
