AIMS: The purpose of this study was to assess the feasibility of laparoscopic intersphincteric resection (LAP-ISR) for rectal cancer in terms of morbidity, oncological outcomes, and functional results.
METHODS: Thirty-seven patients with primary low rectal cancer cT1-T2 underwent LAP-ISR. Surgical outcomes, pathological results, postoperative complications, oncological outcomes, and functional results were analyzed retrospectively.
RESULTS: Three patients (8.1%) had carcinoma in situ, 22 (59.5%) had pT1 tumor, and 11 (29.7%) had pT2 tumor. Eleven patients (29.7%) were diagnosed as being node positive, while 26 (70.3%) had node-negative disease. The median operative time was 315 min (range: 195-502). The median blood loss was 37 ml (range: 0-745). One case was converted to open surgery. Pathological complete resection was achieved in all cases. There was no surgical mortality. Postoperative complications of grade III-IV on the Clavien-Dindo classification were observed in 16.2% of the patients. The median follow-up period was 2.8 years (range: 187-2,241 days), and 3-year disease-free survival was 93.1%. No patient developed local recurrence. The functional result was objectively good.
CONCLUSION: LAP-ISR can be recommended as a feasible, ultimate sphincter-preserving procedure with acceptable functional and intermediate-term oncological outcomes in patients with cT1-T2 very low rectal cancer.
