Abstract

To describe a mesentery-preserving, nerve-sparing laparoscopic technique for rectal endometriosis. Retrospective cohort study. Single centre. Women requiring bowel resection for rectal endometriosis. Full-thickness anterior lesion excision and mesorectum-preserving limited posterior resection with hand-sewn anastomosis, compared with conventional stapled resection. Anastomotic integrity and 12-month functional outcomes. The technique safely preserves neurovascular structures. Initial proof-of-concept data confirm surgical feasibility. This approach is feasible and hypothesis-generating, supporting future prospective trials.
