Laparoscopic Coloanal Anastomosis for Low Rectal Cancer

چکیده
OBJECTIVES Low anterior resection with hand-sutured coloanal anastomosis for low rectal cancer is technically feasible, and it does not compromise oncologic results. We describe herein the effectiveness of the operation in treating low rectal cancer by a laparoscopic approach followed by intraanal canal dissection. METHODS From February 1999 to October 1999, we used a laparoscopic procedure to divide the inferior mesenteric vessels and to dissect downward into the pelvic cavity as low as possible. A purse-string suture 1-cm distal to the lower margin of the tumor was secured and transection of the rectum was performed circumferentially via the anal canal near the dentate line. The specimen was removed by the pull-through method and coloanal anastomosis was completed with hand suture. A protective loop ileostomy was fashioned. RESULTS We operated on 8 patients (4 males) with low tumor localization (average 4-cm above the dentate line). The age ranged from 45 to 83 years, with a median age of 64. The average operation time was 210 minutes (150 to 360 minutes), and the average blood loss was 250 cc (minimal to 750 cc). No operative mortalities occurred, but 2 patients had minor anastomotic slough complications. The average hospital stay was 13 days (7 to 26 days). The postoperative pathologic stage was T2N0M0 in 4 patients, T3N0M0 in 2 patients, T2N1M0 in 1 patient, and T3N2M0 in 1 patient. No local recurrence or distant metastasis occurred during the median 14 months (12 to 20 months) of follow-up. CONCLUSION Laparoscopic coloanal anastomosis combined with intraanal canal dissection is safe and technically feasible. The oncologic results seem not to be compromised, but need further evaluation.
