The risk of abdominal surgery in patients with end-stage renal failure is poorly defined. Our objective was to describe outcomes of colorectal surgery in dialysis patients from a population-based perspective. ⋯ Patients receiving dialysis treatment have an increased risk of morbidity and mortality following colorectal surgery. Elective procedures are associated with a 10% rate of mortality in this population. Dialysis patients are especially susceptible to infectious and pulmonary complications after colorectal resection. Additional studies are necessary to refine risk stratification in this high-risk patient population.

Randomized Controlled Trial
Barrier wound protection decreases surgical site infection in open elective colorectal surgery: a randomized clinical trial.
Surgical site infection following colorectal surgery is a frequent and costly problem. Barrier protection at the time of this form of surgery has been used with varying results. The aim of this randomized study was to examine the efficacy of barrier retractional wound protection in the prevention of surgical site infections in open, elective colorectal surgery. ⋯ In this study the use of barrier wound protection in elective open colorectal resectional surgery resulted in a clinically significant reduction in incisional surgical site infections. Barrier wound protection of this nature should be considered routine in this type of surgery.

It is well recognized that the increased risk of a postoperative venous thrombotic event extends beyond the inpatient treatment period. The purpose of this study was to determine the 30-day incidence and risk factors associated with the occurrence of early postdischarge symptomatic venous thromboembolic events in patients who have undergone major colorectal surgery. ⋯ This study has identified risk factors that may help stratify patients into different risk profiles and offer prolonged prophylaxis to patients at increased risk on the basis of preoperative risk factors and postoperative complications.

This study was conducted to identify prognostic factors affecting the course of ischemic colitis and to develop a prognostic scoring model. ⋯ Endoscopic findings and instability of vital signs were associated with the disease course of ischemic colitis. A novel scoring model based on presence of tachycardia, shock within 24 hours after admission, and endoscopic evidence of ulceration provides a method of assessing patient prognosis and should be further validated.

Rectovaginal fistula is a distressing condition for patients and for physicians who are continuously challenged in providing durable treatment options. The aim of this study is to assess the results of rectovaginal fistula repair and identify predictive factors for poor outcome. ⋯ Despite a relatively low initial success rate (60%), most rectovaginal fistulas can be successfully repaired with subsequent operations. Crohn's disease and smoking are associated with adverse outcomes.
