    Abstract:
    In rectal cancer the emphasis has moved towards sphincter saving resection. Tumor site and penetration depth decide the operative technique in low rectal cancer. 1) Resection at the upper confinement of the anal canal. 2) Intersphincteric resection at the level of the dentate line. Reconstruction is achieved by a colonic J-pouch. From 1991 to 1994 we operated on 35 patients with an average age of 58.1 years. An intersphincteric resection was performed in 11 patients whose tumor was situated between 0 and 2 cm upwards the dentate line. 24 cancers were situated between 2 and 6 cm of the dentate line and were resected at the upper confinement of the anal canal with a linear stapler. Tumor penetration depth was determined endosonographically (ES). Four patients had tumor stage ES T1, 13 ES T2 and 18 ES T3. A J-pouch of 7-9 cm size was sutured (11) or stapled (24) to the anal canal. In 10 patients who underwent intersphincteric resection the pre- and post-operative anal pressures were determined. We did not encounter major complications. In three patients a leakage at the colonal anastomosis postponed closure of the diverting colostomy. We had no anastomotic recurrence but one pelvic side recurrence. Four patients developed liver metastases; in one case resectable. Postoperative anal sphincter pressure was reduced in all cases but clinically relevant only in one. This patient has frequent major soiling, three patients have occasional minor leak. Two patients are incontinent of gas, 26 are perfect continent. One patient has bowel movements every two days, 15 one per day, 12 two per day and 3 three per day.(ABSTRACT TRUNCATED AT 250 WORDS)
