Over the last decade, the laparoscopic approach to antireflux surgery has been widely applied, resulting in improved early outcomes and greater patient acceptance of surgery for gastroesophageal reflux disease. However, although short-term outcomes are probably better overall than those following open surgery, it has become apparent that the laparoscopic approach is associated with an increased risk of some complications, and as well as the occurrence of new complications specific to the laparoscopic approach. ⋯ In addition, laparoscopic reintervention is usually straightforward in the 1st postoperative week. For this reason, the surgeon should have a low threshold for early laparoscopic reexploration, facilitated by early radiological contrast studies, in order to reduce the likelihood that problems will arise later.

Although many aspects of laparoscopic surgery have been determined, the question of which insufflation gas is the best arises repeatedly. The aim of this study was to review the findings on the major gases used today in order to provide information and guidelines for the laparoscopic surgeon. ⋯ Clearly, CO(2) maintains its role as the primary insufflation gas in laparoscopy, but N(2)O has a role in some cases of depressed pulmonary function or in local/regional anesthesia cases. Other gases have no significant advantage over CO(2) or N(2)O and should be used only in protocol studies. The relation of port-site metastasis to a specific type of gas requires further research.

Review Case Reports
Active electrode monitoring. How to prevent unintentional thermal injury associated with monopolar electrosurgery at laparoscopy.
In recent years, the use of minimally invasive surgery (MIS) has expanded to a wide variety of surgical specialties. The increased popularity of the procedure, however, has been accompanied by its share of complications, including trocar lacerations and inadvertent thermal injuries to nontargeted tissues during monopolar electrosurgery. ⋯ To reduce the incidence of injury by monopolar electrosurgery at laparoscopy, there is a need for advanced technology, such as AEM. In addition, laparoscopic surgeons should be encouraged to study the basic concepts of the biophysics of electrosurgery.

The acute abdomen in the pregnant patient poses a difficult diagnostic and therapeutic challenge to the surgeon. Appendicitis, cholecystitis, and bowel obstruction account for the majority of the abdominal pain syndromes which require surgical intervention. Laparoscopy is being used increasingly in the diagnosis and operative management of these disorders. ⋯ Laparoscopy can be a useful means of diagnosis and in addition a therapeutic tool in selected pregnant patients with abdominal pain. Close maternal and fetal monitoring is essential during and after the procedure. Laparoscopic cholecystectomy is safe and can be performed without additional risk to the fetus for those who require surgical intervention during pregnancy.

Review Case Reports
Laparoscopic bilateral inguinal hernia repair under local anesthesia.
A case report of the laparoscopic repair of bilateral inguinal hernias performed under local anesthesia with intravenous sedation is presented. The combination of nitrous oxide for peritoneal insufflation and an ultrasonically activated scalpel for dissection made the procedure feasible. It is hoped that this technique can extend laparoscopic surgery to patients who are poor candidates for general anesthesia.
