Abstract
INTRODUCTION: Incomplete specimens resulting in residual mesorectum in the patient and an increased risk of local recurrence remains a problem. We have introduced transanal-total mesorectal excision (Ta-TME) in our department to potentially overcome this problem due to more direct access to the lower pelvis in patients undergoing TME for rectal cancer and this article presents our initial experience with the new procedure. MATERIALS AND METHODS: Patients with a T1-T3 mid or low rectal cancer eligible for TME or intersphincteric abdominoperineal excision were selected for a combined transanal and transabdominal laparoscopic resection. The primary aim of the study was to evaluate the feasibility and efficacy of the method with a special focus on the quality of the specimen. RESULTS: During a 9-month period, 11 patients were operated with this technique. All procedures resulted in complete or nearly complete specimen. We did, however, find the procedure technically demanding and experienced several complications with three anastomotic leaks (all with preserved intestinal continuity) and a urethral lesion. CONCLUSION: Ta-TME is feasible and might be the answer to obtaining good quality specimens and overcome some of the technical difficulties that can be encountered in the obese narrow male pelvis. The procedure however is technically demanding.
