A correct surgical approach to rectal cancer today has to make due allowance for both improved overall survival with local control of disease and preservation of the sphincter and urinary and genital functions. Increased understanding of the natural history, the importance of preoperative accurate staging and new surgical techniques may influence future treatment strategies. The aim of this study was to review and make a reappraisal of the role of sphincter-preserving surgery in the treatment of carcinomas of the lower third of the rectum. From January 1999 to June 2004, 63 consecutive total rectal resections were performed at our surgical department. Thirty-five of these patients, who underwent surgery for a primary adenocarcinoma of the distal rectum (3.5 to 8 cm from the anal verge), were reviewed retrospectively. The preoperative clinical assessment was based largely on T staging, tumor size, fixation and distance from the anal verge. Patient stratification, based on the definitive pathological report, was 3 Dukes' stage A (T1 N0), 21 stage B (T2 N0) and 11 stage C (T2-3-4 N+). The distance from the anal verge was > 5 cm in 30 patients and < 5 cm in 5. Sphincter-saving procedures were performed in 28/35 patients (80%); 7 (20%) had abdominoperineal resections of the rectum for very distal, locally extensive tumours or local recurrence (2 patients). The overall recurrence rate was 11.4%. Postoperative morbidity related to the procedures was low: anastomotic leakage occurred in 10.7% (3/28). Perfect continence was documented in 86.3%. The minimum follow-up time is 12 months. Our data, in agreement with the findings of other Authors, appear to bear out the validity of sphincter-saving procedures in the treatment of cancer of the lower third of the rectum. This approach is possible for the majority of patients. Functional results are good, using an accurate nerve-sparing technique, and may be improved by employing a colonic reservoir in selected cases.

Polyps occur throughout the gastrointestinal tract in Peutz-Jeghers syndrome, but the most serious problems are encountered in the management of small bowel polyposis. We report here on a case of Peutz-Jeghers syndrome admitted to hospital for intestinal obstruction and anaemia. The patient was submitted to colonoscopy, oesophagogastro-duodenoscopy and small bowel enema. At laparotomy, multiple intussusceptions were found and we conducted a combined surgical-endoscopic approach. Most of the polyps were identified and removed endoscopically (snare polypectomy). Five enterotomies were performed to remove 18 very large polyps (> 3 cm). Finally, a limited portion of the jejunal tract (20 cm) was resected owing to the presence of multiple, large, obstructive polyps. None of the polyps showed cancerous transformation. The shortcomings of the traditional surgical approach include repeated small bowel resections and often early reoperation to manage complications caused by polyps missed at the time of previous surgery. If surgical intervention is required, intraoperative endoscopy is always indicated. Conservative surgical management, the role of intraoperative endoscopy, planned medical follow-up and the need for a national registration system are stressed.
