Pseudoaneurysm of the inferior gluteal artery: an unusual complication after abdominoperineal resection for rectal cancer. Report of a case.

We report an unusual case of profuse, sporadic hemorrhage from a chronically infected perineal wound after an abdominoperineal resection. Surgical exploration and angiography on two occasions failed to identify the source of bleeding. A pseudoaneurysm of the internal iliac artery was eventually identified with a provocative angiogram using tissue plasminogen activator. This aneurysm was successfully treated with embolization with coils.

Preservation of bowel and urinary continence in the management of locally recurrent rectal cancer.

BACKGROUND: The management of locally recurrent rectal cancer should achieve local tumor control and potentially improving disease-free and overall survival. Radical pelvic resection has traditionally been associated with permanent fecal and urinary diversion. However, as advanced techniques have evolved to allow restoration of intestinal and urinary continence, we reviewed the use of these techniques in patients with recurrent rectal cancer. METHODS: Patients with recurrent rectal cancer who underwent a resection at Norris Comprehensive Cancer Center between 1993 and 1999 were retrospectively reviewed. Data collected included demographic data, surgical and oncological history, patterns of recurrence, treatment modalities, and outcome. Follow-up data was obtained from the last clinic visit and/or tumor registry. RESULTS: Sixty-seven patients with locally recurrent rectal cancer (male/female 45/22, age 32-81 years) were included in the analysis. Continence was re-established in 22 (33%) patients, urinary continence was restored in 12 patients, and intestinal continuity in 14 patients (both in 4 patients). A temporary diverting ostomy was necessary in 5 out of 14 (36%) patients. Mortality was zero and morbidity was low and included two urinary leaks and one fecal leak all of which could be managed non-operatively. At a median follow-up of 16 months (range 5-55), 11 (50%) patients were still alive, 7 (31%) without evidence of disease. Comparison of the groups of patients either with or without continence preservation showed no statistically significant difference in disease-free survival and overall survival rates. High quality of life was achieved with restoration of continuity, no patient with restored continuity expressed a desire for a diversion. CONCLUSION: If an oncologically adequate resection of the recurrent rectal cancer can be performed without impairment of the pelvic floor integrity, continence preservation is feasible and results in good functional and oncological outcome.

Fistula-in-ano: do antibiotics make a difference?

BACKGROUND: The objective of this study was to evaluate the hypothesis that antibiotics in conjunction with drainage of anorectal abscesses will reduce the incidence of fistulae formation. The impact of age and associated comorbidity on the formation of fistulae were also evaluated. METHODS: Patients with a diagnosis of anorectal abscesses were identified from the database of a single colorectal practice. Demographic data, comorbidity, antibiotic usage, and fistulae formation were collected from review of patient's charts and phone contact. Statistical analysis was performed with the two-sided Fisher's exact and Wald's chi-square tests. RESULTS: Fifty-six patients with complete data were analyzed. The overall fistulae formation rate was 32%. Of all patients, 45% received a course of broad-spectrum antibiotics at the time of drainage and 48% of patients had associated comorbidity. Although trends were evident, there were no statistical significant associations between fistulae formation and age, comorbidity, and antibiotics. CONCLUSION: Although not statistically significant, there was a trend that antibiotics and age >45 years may be protective against the formation of fistulae. Similarly, the data suggest that the presence of comorbidity may increase the risk of fistula formation. We are encouraged by this result and propose to conduct a larger randomized prospective study.

Stapled hemorrhoidectomy.

Stapled hemorrhoidectomy has rapidly evolved and become the procedure of choice for primarily internal hemorrhoids. Even though the technique is relatively straightforward, only strict adherence to its principles will avoid serious complications and preserve the previously described benefits of this method. Recurring questions during teaching courses as well as several pitfalls that might result in suboptimal outcomes have prompted us to highlight some important details and modifications of the surgical technique.
