Risk factors associating with delayed gastric emptying after laparoscopic distal gastrectomy.

PURPOSE: The aim of this study was to investigate the incidence of delayed gastric emptying among the patients receiving laparoscopic distal gastrectomy, and to explore their clinical features and risk factors. METHODS: Clinical data were collected for 223 patients who underwent laparoscopic distal gastrectomy for gastric cancer. We retrospectively evaluated the clinicopathological features and analyzed the incidence of delayed gastric emptying among 223 patients. Delayed gastric emptying was diagnosed by patient's symptoms and the plane radiograph with an air fluid level and dilation of the remnant stomach. RESULTS: Delayed gastric emptying was found in five (2.2%) of the 223 patients. By univariate logistic regression analysis, greater American Society of Anesthesiologists Physical Status (ASA-PS) and older age were significantly related to occurrence of delayed gastric emptying. By multivariate logistic regression analysis, older age was independently significantly related to incident delayed gastric emptying. The area under the curve (AUC) ((95% CI) of the receiver operating characteristic (ROC) was 0.842 (0.561-0.957). The best cutoff for discriminating patients with and without delayed gastric emptying was 80 years (sensitivity 80% and specificity 83%). CONCLUSION: Our study found the occurrence of delayed gastric emptying is possibly correlated with age. Therefore, careful perioperative observation in elderly patients may possibly be important for possible development of delayed gastric emptying after laparoscopic distal gastrectomy.

Repair of a perineal hernia with a bladder patch after abdominoperineal resection: A case report and literature review.

Perineal hernia is the protrusion of the intra-abdominal viscera through the pelvic floor. It rarely occurs after abdominoperineal resection but has increasingly occurred after surgical treatment for rectal cancer. A patient was diagnosed as having perineal hernia 10 days after laparoscopic abdominoperineal resection with preoperative radiotherapy and chemotherapy. He presented with epigastric discomfort and perineal wound dehiscence. Perineal hernia was confirmed by computed tomography scan and treated with a semi-emergency surgery. The surgical field was contaminated because of the perineal wound dehiscence. The levator muscle at the pelvic floor was not sufficient, so we used a bladder patch to cover the pelvic inlet. The surgery was performed without any adverse events. To our best knowledge, this is the first case report to present the usefulness of a bladder patch for the treatment of a perineal hernia using a laparoscopic transabdominal approach in emergency situations.
