Clinical Outcome of Laparoscopic Intersphincteric Resection Combined with Transanal Rectal Dissection for T3 Low Rectal Cancer in Patients with a Narrow Pelvis

الملخص EN

Purpose.

The purpose of this study was to analyze the safety and feasibility of laparoscopic intersphincteric resection (ISR) combined with transanal rectal dissection (TARD) for T3 low rectal cancer in a narrow pelvis.

Methods.

We studied 20 patients with a narrow pelvis of median body mass index 25.3 (16.9–31.2).

Median observation period was 23.6 months (range 12.2–56.7).

Results.

Partial, subtotal, and total ISR was performed in 15, 1, and 4 patients, respectively.

Median duration of TARD was 83 min (range 43–135).

There were no major complications perioperatively or postoperatively.

Surgical margins were histologically free of tumor cells in all patients, and there was no local recurrence.

Excluding urgency, frequency of bowel movements, and incontinence status improved gradually after stoma closure.

Conclusion.

Laparoscopic ISR combined with TARD is technically feasible for selective T3 low rectal cancer in patients with a narrow pelvis.
