Resection of the rectum and total excision of the internal anal sphincter with smooth muscle plasty and colonic pouch for treatment of ultralow rectal carcinoma,

G. I. Vorobiev
Background: Intersphincteric resection can provide tumour-free margins for rectal tumours located 0,1 cm above the dentate line. However, the internal anal sphincter (IAS) is partially or totally resected and some degree of anal incontinence may develop. A novel technique of smooth muscle plasty of the IAS and colonic pouch construction is described, along with an assessment of morbidity, oncological results and functional outcome. Patients and methods: Between 1997 and 2002, 27 patients (16 men; median age 55 (range 26,75) years) were operated on for T2,3 N0,1 M0 rectal carcinoma located a median of 1·0 (range 0·5,1·5) cm from the dentate line. Resection of the IAS was performed transanally. A smooth muscle cuff, fashioned from the muscular layer of colon, and a colonic pouch were used for anorectal reconstruction. Results: There were no perioperative deaths. Anastomotic leakage developed in two patients. After a median follow-up of 38 (range 14,66) months no local recurrence was detected. Distant metastases occurred in three patients, two of whom died. Perfect functional outcome was achieved in 22 of 26 patients. At 6 months after surgery the mean(s.d.) resting anal pressure was 49(8) mmHg. Conclusion: In selected patients intersphincteric resection does not compromise the oncological result. The suggested anorectal reconstruction may improve the functional outcome. Copyright © 2004 British Journal of Surgery Society Ltd. Published by John Wiley & Sons, Ltd. [source]

Laparoscopic intersphincteric resection with coloplasty and coloanal anastomosis for mid and low rectal cancer,

BRITISH JOURNAL OF SURGERY (NOW INCLUDES EUROPEAN JOURNAL OF SURGERY), Issue 4 2003
E. Rullier
Background: The feasibility of laparoscopic rectal resection in patients with mid or low rectal cancer was studied prospectively with regard to quality of mesorectal excision, autonomic pelvic nerve preservation and anal sphincter preservation. Methods: Laparoscopic rectal excision was performed in 32 patients (21 men) with rectal carcinoma located 5 cm from the anal verge. Most patients had T3 disease and received preoperative radiotherapy. The surgical procedure was performed 6 weeks after radiotherapy and included total mesorectal excision, intersphincteric resection, transanal coloanal anastomosis with coloplasty and loop ileostomy. Results: Three patients needed conversion to a laparotomy. Postoperative morbidity occurred in ten patients, related mainly to coloplasty. Macroscopic evaluation showed an intact mesorectal excision in 29 of 32 excised specimens; microscopically, 30 of the 32 resections were R0. Sphincter preservation was achieved in 31 patients. The hypogastric nerves and pelvic plexuses were identified and preserved in 24 of the 32 patients. Sexual function was preserved in ten of 18 evaluable men. Conclusion: A laparoscopic approach can be considered in most patients with mid or low rectal cancer. Copyright © 2003 British Journal of Surgery Society Ltd. Published by John Wiley & Sons, Ltd.

B001 Multicentre Randomized Trial of Sphincter Preserving Surgery for Ultra-Low Rectal Carcinoma

COLORECTAL DISEASE, Issue 2006
E. Rullier
Objective, This randomized study compared two neoadjuvant treatments in patients with a low rectal cancer less than 2 cm from the anal verge that would have required APR before radiotherapy. Method, A total of 207 patients (71% uT3) with a rectal carcinoma at 0.5 cm from the anal verge were randomized in two groups. The group HDR received a high dose of radiotherapy (45 Gy + boost 18 Gy). The group RCT received 45 Gy with concomitant chemotherapy (5FU). Surgery was performed 6 weeks after treatment, surgeons were trained with TME, APR and intersphincteric resection. Results, The rate of sphincter preserving surgery was 83% after HDR and 86% after RCT (P = 0.69). There was no difference in morbidity, clinical tumour regression (80% vs. 87%) and complete pathological response (8% vs. 15%) between HDR and RCT. Overall, the rate of R0 resection was 78%. After a follow-up of 23 months, the rates of local and distant recurrence were 6% and 19% respectively and the disease-free survival was 77%. Survival was better after sphincter preservation than after APR. Conclusion, Sphincter preservation was achieved in 85% of ultra-low rectal carcinomas without compromising oncological prinicples. No difference was observed between HDR and RCT. Further follow-up is necessary to confirm this conservative approach. [source]
