Case Reports
Diaphragmatic hernia resulting from injury during microwave-assisted laparoscopic hepatectomy.
A 31-year-old woman underwent microwave-assisted laparoscopic hepatectomy of the left lateral segment for focal nodular hyperplasia on January 14, 1998. On September 9, 1998, she felt continuous left abdominal pain and was admitted to our hospital for further examination. An upper gastrointestinal series showed converging folds of the greater curvature of the upper third of the stomach and craniad displacement of this portion. ⋯ The stomach was returned to the peritoneal cavity and the defect sutured. The patients postoperative course was uneventful. Although diaphragmatic hernia after laparoscopic surgery is a rare complication, with the performance of more advanced laparoscopic procedures and the use of higher-technology tissue-destruction/hemostatic devices such as the microwave coagulator, more caution should be observed to prevent injury to adjacent organs such as the diaphragm.

Randomized Controlled Trial Comparative Study Clinical Trial
A prospective randomized study of prophylactic antibiotics in elective laparoscopic cholecystectomy.
Elective laparoscopic cholecystectomy (LC) has a low risk for infective complications, but many surgeons still use prophylactic antibiotics. The use of prophylactic antibiotics for LC is inconsistent and varies widely among surgeons. ⋯ In patients undergoing elective LC, antibiotic prophylaxis is justified only in high-risk patients. In all other patients, antibiotic prophylaxis does not seem to affect the incidence of postoperative infective complications. In low-risk patients, eliminating the unnecessary use of prophylactic antibiotics would result in a cost reduction; moreover, it would lower the risk of adverse reaction and reduce microbial resistance.

Laparoscopic fenestration is considered the best treatment for symptomatic simple liver cysts. Conversely, the laparoscopic approach for the management of hydatid simple liver cysts is not widely accepted because of the risk for severe complications. Despite improvement in imaging techniques, the probability of preoperatively mistaking a hydatid liver cyst for a simple liver cyst remains about 5%. Therefore, laparoscopic fenestration, planned for a liver cyst could be performed unintentionally for an undiagnosed hydatid liver cyst. ⋯ The risk of misdiagnosing a hydatid liver cyst for a simple liver cyst, especially in the presence of a solitary cyst, should be considered before laparoscopic fenestration is performed. Intraoperative aspiration of cyst fluid before fenestration can minimize this risk, thus avoiding severe intraoperative and late complications.

Comparative Study
A prospective study comparing the complication rates between laparoscopic and open ventral hernia repairs.
Although ventral hernia repair is increasingly performed laparoscopically, complication rates with this procedure are not well characterized. For this reason, we performed a prospective study comparing early outcomes after laparoscopic and open ventral hernia repairs. ⋯ The patients undergoing laparoscopic repair had fewer postoperative complications than those receiving open repair. Wound infections and postoperative ileus accounted for the higher complication rates in the open ventral hernia repair group. Otherwise, these groups were very similar. Long-term studies assessing hernia recurrence rates will be required to help determine the optimal approach to ventral hernia repair.
