ABSTRACT

Objective: Laparoscopic colectomy has gained acceptance as a standard treatment for benign and malignant colorectal disease, such as diverticular disease and cancer, among others. Same as in open surgery, the laparoscopic approach carries a low risk of small bowel obstruction in the postoperative period, but in laparoscopic surgery, internal hernia after laparoscopic left colectomy may be a cause of small bowel obstruction with a significant risk of morbidity and mortality. This rare complication may be prevented with routine closure of the mesenteric defects created during the colectomy. Methods: We present four cases of internal herniation after laparoscopic colectomy. Two cases were after laparoscopic left colectomy and two after laparoscopic low anterior resection. All four cases had full splenic flexure mobilization. Routine closure of the mesenteric defect was not performed in the initial surgery. Results: The four patients were treated by laparoscopic reintervention with closure of the mesenteric defect. In two of them, conversion to open surgery was necessary. One of the patients developed recurrent internal herniation after surgical reintervention with mesenteric closure of the defect. All patients were managed without need for bowel resection, and mortality rate was 0%. Conclusion Internal herniation after laparoscopic colorectal surgery is a highly morbid complication that requires prompt diagnosis and management and should be suspected in the early postoperative period. Additional studies with extended follow-up are required to establish recommendations regarding its prevention and management. (AU)

ABSTRACT

PURPOSE: Obese patients are generally believed to be at increased risk for surgery compared to those who are not obese. It was the purpose of this study to compare the short-term outcomes of a laparoscopic low anterior resection (LAR) in obese and non-obese patients. METHODS: We retrospectively reviewed 79 patients who had undergone a laparoscopic LAR for rectal cancer between September 2002 and January 2008. The degree of obesity was based on the Body Mass Index (BMI, kg/m2). We divided the 79 patients into two groups: the high BMI (BMI> or =25) and the low BMI (BMI <25) groups. The parameters analyzed included age, gender, American Society of Anesthesiologists classification score, operative time, estimated blood loss, conversion rate, postoperative complications, hospital stay, and oncologic characteristics. Statistics included the t-test and Fisher's exact test. Statistical significance was assessed at the 5% level (P<0.05 being statistically significant). RESULTS: There were no significant differences between the low BMI (n=55) and the high BMI (n=24) groups in age and gender. The high BMI group had significantly more conversion to an open procedure (20.8% vs. 3.6%, P=0.0244). The high BMI group and the low BMI group had no differences in blood loss, complications, hospital stay, and oncologic characteristics, but the high BMI group had a longer operative time (244.2 min vs. 212.0 min, P=0.0035). CONCLUSION: A laparoscopic LAR in obese patients had a higher conversion rate and a longer operative time, but there were no differences in postoperative complications and oncologic characteristics. A further study based on many experiences is needed to clarify the influence of the surgeon's experience on the operative time and the conversion rate, and long-term follow-up is necessary to evaluate the oncologic safety of a laparoscopic LAR in obese patients.
