ABSTRACT
UNLABELLED: For the past decade peroral, orthograde, polyethylene glycol-electrolyte lavage solutions (PEG-ELS) have been the preferred bowel-cleansing regimens before diagnostic and therapeutic procedures on the colon and rectum. The large volume and unpalatibility of these solutions may lead to troubling side effects and poor patient compliance. PURPOSE: This study was undertaken to determine which of various colon-cleansing methods before colonoscopy would provide greater patient acceptance while maintaining similar or improved effectiveness and safety. METHODS: Three hundred twenty-nine patients undergoing elective ambulatory colonoscopy were prospectively randomized to one of three bowel preparation regimens. Group 1 received 41 of PEG-ELS (n = 124). Group 2, in addition to PEG-ELS, received oral metoclopramide (n = 99). Group 3 received oral sodium phosphate (n = 106). All groups were evenly matched according to age and sex. RESULTS: Ninety-one percent of all patients completed the preparation received. Sixteen percent of patients suffered significant sleep loss with a bowel preparation. When comparing the three groups, there was no difference in the assessment of nausea, vomiting, abdominal cramps, anal irritation, or quality of the preparation. Compared with other preparations, oral sodium phosphate was better tolerated. More patients completed the preparation (P < or = 0.001). Fewer patients complained of abdominal fullness (P < or = 0.001). More patients were willing to repeat their preparation (P < or = 0.02). Also, sodium phosphate was found to be four times less expensive than either of the PEG-ELS preparations. CONCLUSION: All regimens were found to be equally effective. Abdominal symptoms and bowel preparation were not influenced by the addition of metoclopramide. The oral sodium phosphate preparation was less expensive, better tolerated, and more likely to be completed than either of the other preparations.

Sixty-seven abdominal operations for colon and rectal disorders were performed on 56 patients 80 years of age or older from January 1, 1984 to June 30, 1989. Nine patients required multiple operations. Sixty-two procedures (92 percent) were performed on patients in their ninth decade; two operations were performed on patients 95 years of age or older. Forty-five patients (80 percent) were operated upon for carcinoma. Operations included segmental colectomy (33 patients), low anterior resection (12 patients), total abdominal colectomy (3 patients) and abdominoperineal resection (2 patients). Forty patients were classified as ASA Class III; the majority were monitored in the surgical intensive care unit for a mean of 2.84 days. Thirty patients were monitored with arterial catheters and 21 with central invasive monitoring. Operative mortality was 7 percent (4 patients). Two patients died from diffuse carcinomatosis; one patient had a fatal myocardial infarction. The final death occurred from multisystem organ failure following anastomotic dehiscence. Twenty-seven operations were performed without postoperative complications; 18 operations were followed by a single minor complication. The average hospital stay was 18.96 days. All patients were admitted from home. Thirty-three returned home postoperatively; 16 were discharged to an extended care facility. In conclusion, elderly patients with colon and rectal disorders can be operated upon with acceptable morbidity and mortality. Age alone should not interdict surgical therapy.

Twenty patients with squamous-cell carcinoma of the anal canal received combined chemo-radiation therapy as their primary treatment. There were 18 women and two men with a mean age of 63 years (range, 34-91 years). The mean follow-up was 34 months (range, 6-62 months). Anal margin cancers and adenocarcinomas were excluded. Fourteen of 20 patients treated had a complete response. There were six local failures: three with residual disease at the end of treatment and three with recurrent disease at a later date. Of the three with residual disease, one underwent abdominoperineal resection and two received salvage therapy (one with chemo-radiation and one with radiation alone). All three patients with recurrent disease were treated with abdominoperineal resection. All six were disease free at the end of the study. Of the 14 patients with complete local response, one presented with liver metastases 19 months later. Sixteen patients (80 percent) were alive at the end of the study, and 19 patients (95 percent) had no evidence of disease. These data add support for salvage therapy in the treatment of patients with residual disease following initial chemo-radiation therapy. Salvage options for patients with squamous-cell carcinoma of the anus who fail the Nigro protocol will be discussed.

Forty women with low rectovaginal fistulas were operated upon over a 9-year period. The etiology of the fistula in the majority was obstetric. Nine women had prior attempts to repair the fistula. All 40 women were managed with endorectal advancement flap with the addition of sphincteroplasty or perineal body reconstruction in 15 patients and rectocele repair in six patients. Postoperative complications included urinary difficulties (two patients) and wound complications (three patients). There were two recurrences. All women treated with sphincteroplasty or perineal body reconstruction were continent. Seven women complained of varying degrees of incontinence postoperatively; none had undergone sphincter or perineal body reconstruction. Endorectal advancement flap is a safe and effective operation for women with rectovaginal fistulas. Concomitant sphincteroplasty or perineal body reconstruction should be performed in women with historical, physical, or manometric evidence of incontinence.
