Abstract
Abstract Aim Laparoscopic transanal minimally invasive surgery (Lap-TAMIS) is an established transanal surgical approach in colorectal practice. This study evaluated the feasibility and perioperative outcomes of Lap-TAMIS following its introduction at a district general hospital. Methods A retrospective review was conducted of consecutive patients undergoing Lap-TAMIS between 2018 and 2025. Outcomes assessed included histopathology, procedural completion, length of stay (LOS), postoperative morbidity, local recurrence, and requirement for further intervention. Patients were stratified into benign and malignant cohorts based on final histology. Results Eighty-seven patients underwent Lap-TAMIS (median age 76 years; male:female 48:39). Median lesion size was 3.1 cm (maximum 12 cm), with distance from the anal verge of 6 cm (range 1-15cm). Median operative time was 60 minutes, LOS was one day, and follow-up 36 months. Procedural completion was achieved in 98.8% of cases. Postoperative complications occurred in 10% of patients, limited to Clavien–Dindo grade I–II events and there was no procedure-related mortality. In the benign cohort (n=65, 75%), local recurrence occurred in 11 patients at a median of one year and was predominantly managed with repeat Lap-TAMIS or endoscopic resection. In the malignant cohort (n=22, 25%), nine patients had T2 tumours. Kaplan–Meier analysis demonstrated recurrence-free survival was maintained in most malignant cases, with recurrence in one patient at nine months following an initial R0 resection, requiring radical surgery. Conclusion Lap-TAMIS demonstrates favorable feasibility and safety, with high procedural success, short hospital stay, and low morbidity, supporting its use as an organ-preserving approach for selected rectal lesions.
