Long-term results of anterior resection using the double-stapling technique.

PURPOSE: This study was designed to determine the anastomotic leak rate, local recurrence rate, and survival of patients undergoing anterior resection with the double-stapling technique for rectal cancer. METHODS: Between 1981 and 1992, 189 patients underwent a curative (166) or palliative (23) anterior resection using the double-stapling technique. A chart review was performed, and follow-up information was obtained from the patient or family physician. Follow-up was complete in 186 patients (98 percent). RESULTS: There were five (2.6 percent) stapler-related complications, of which two patients required a defunctioning colostomy. Postoperative mortality was 1.6 percent, and clinical leak rate was 7.3 percent. Clinical leak rate was significantly higher in patients with lesions in the lower third (20 percent) compared with those in the middle and upper thirds (9 and 1 percent, respectively; P < 0.05). After a mean follow-up of 32 +/- 29 months, local recurrence rate was 9.1 percent but was significantly higher in patients more than 65 years old (14 vs. 1 percent; P < 0.005) and in patients with resection margins less than 2.0 cm (17 vs. 5.5 percent; P < 0.05). Five-year survival was 78 percent. CONCLUSIONS: Anterior resection performed with the double-stapling technique has an acceptable clinical leak rate, local recurrence rate, and survival rate. However, the clinical leak rate appears to be increased in patients with low tumors and, therefore, a defunctioning colostomy should be considered. Resection margins of more than 2 cm are necessary.

Spontaneous resolution of rectal polyps in patients with familial polyposis following abdominal colectomy and ileorectal anastomosis.

One hundred sixteen patients were reviewed after abdominal colectomy and ileorectal anastomosis (IRA) for familial polyposis to determine the rate of postoperative spontaneous regression of rectal polyps. The failure of the IRA procedure was correlated with the preoperative number of rectal polyps and the degree of rectal polyp regression. Spontaneous resolution of rectal polyps occurred in 64 percent of the patients (complete 38 percent, partial 26 percent). In those patients initially having complete resolution, 55 percent redeveloped polyps during follow-up. With a mean follow-up of 9.3 years, seven patients have developed rectal cancer. Rectal cancer development was more common in those patients who had innumerable rectal polyps prior to IRA. Initial polyp regression did not preclude later development of rectal cancer. There were 11 deaths during the follow-up period, but only one of these was from rectal cancer. Abdominal colectomy and IRA is an effective treatment for familial polyposis. Spontaneous regression of polyps occurred in 64 percent of patients, but continuous and complete follow-up is necessary to fulgurate recurrent polyps and to screen for the development of cancer.

Complications of loop ileostomy.

We consider a proximal loop ileostomy to be an integral part of a pelvic pouch procedure with ileoanal anastomosis. In the absence of controlled studies and considering the reported poor results with high rates of pelvic sepsis when this operation is performed without a proximal defunctionalizing ileostomy, we will continue to routinely use proximal ileostomy in all patients undergoing this procedure. There is a high rate of complications related to loop ileostomy; however, they are not life threatening and do not preclude an excellent long-term result. Dehydration requiring readmission to the hospital occurred in 20 percent of the patients in this series. More sensitive clinical data, such as measurement of urinary electrolyte levels, should be used to identify patients at high risk for this complication. Septic complications were rare after closure of the loop ileostomy, but bowel obstruction was common. Bowel obstruction rarely required operative intervention, but it is possible that changing the method of closure may decrease the rate of obstruction. The use of loop ileostomy to bypass temporarily part of the terminal ileum may have significant metabolic effects that require further study.

Quality of life survey of urinary diversion patients: comparison of ileal conduits versus continent Kock ileal reservoirs.

There has been a recent marked increase in interest in continent urinary diversions. While considerable time has been spent on the technical aspects of these diversions the psychological impact has not yet been fully explored. We describe an extensive survey that was conducted among 100 consecutive adults (87 respondents) who had undergone urinary diversion via an ileal conduit and 100 consecutive adults (85 respondents) in whom a continent Kock ileal reservoir was created during the last 3 to 5 years at our university by the same surgeons. The Kock pouch patients were stratified further into 63 with primary diversion and 22 who underwent conversion from previous conduit diversions. The survey consisted of a questionnaire that included a social and sexual survey, the Beck Depressive Inventory, the Profile of Mood States and a physical impact study. The results revealed that all patients surveyed generally were satisfied with the diversions and they had adapted reasonably socially, physically and psychologically. The key to adaptation seemed to be a detailed, realistic preoperative education about the type of diversion used. Patients with ileal conduit diversions had the lowest expectations of the form of diversion as defined by the preoperative awareness of the need to wear an external ostomy appliance with its associated inconveniences and change in the external body image. Postoperatively, ileal conduit patients also had the poorest self images as defined by a decrease in sexual desire and in all forms of physical contact (sexual and nonsexual). The subset of patients who underwent conversion from conduit diversions to Kock pouches, however, were statistically the most satisfied, and they were the most physically and sexually active. We conclude that the Kock continent urostomy offers an important alternative to noncontinent forms of diversion.

Bladder outlet obstruction by so-called lymphomatoid granulomatosis (angiocentric lymphoma).

Lymphomatoid granulomatosis is an angiocentric, lymphoproliferative disease of the lung, which frequently involves extrapulmonary sites. Controversy persists over whether this process represents malignant lymphoma from its inception. Historically, the disease generally carries a poor prognosis but aggressive chemotherapy has resulted in improved survival. We describe a patient who presented with bladder outlet obstruction resulting from prostatic infiltration by this angiocentric lymphoproliferative disease. The clinical manifestations, pathological appearance and therapeutic options are reviewed.

The double stapling technique for low anterior resection of rectal carcinoma.

The double stapling technique (TA-55 and EEA staplers) was used to perform low anterior resections for rectal carcinomas in 79 patients (49 men, 30 women). The mean age was 66 years (range, 38 to 85 years). Curative resections were performed in 68 patients, and palliative resections in 11 patients. The mean level of the cancer from the dentate line was 9 cm (range, 5 to 16 cm). The mean follow-up has been 29 months (range, four to 58 months). Perioperative mortality was 2.5 percent (two patients). Technical problems related to the stapling technique occurred in 6 percent (five patients). The clinical anastomotic leak rate was 8 percent (six patients). There were 11 local recurrences among 68 curative resections (16 percent). Local recurrence according to individual surgeon showed marked variability (range, 0-43 percent, P greater than 0.05). There were no differences in location, differentiation, or stage in those that recurred. The mean distal resection margin for the recurrent cancer group was 3.0 cm and for the nonrecurrent group, 2.9 cm. Disturbances of continence were seen commonly (56 percent) in the first three months after surgery, but 85 percent of patients became fully continent with an acceptable bowel habit at later follow-up. The double stapling technique is useful for the restorative resection of suitable mid and low rectal cancers. The anastomotic leak rate, local recurrence rate, and functional results are acceptable.
