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.

Clinical Trial
Laparoscopic cholecystectomy under epidural anesthesia in patients with chronic respiratory disease.
Laparoscopic cholecystectomy (LC) has become firmly established as a procedure of choice for gallstone disease. The procedure usually necessitates general anaesthesia and endotracheal intubation to prevent aspiration and respiratory embarrassment secondary to the induction of pneumoperitoneum. There is a paucity of data in the literature on the procedure being performed under regional (epidural) anaesthesia, especially in patients with coexisting pulmonary disease and pregnancy, who are deemed high risk for general anaesthesia. We report our preliminary experience with LC using epidural anaesthesia in patients with chronic obstructive pulmonary disease (COPD). ⋯ LC can be performed safely under epidural anaesthesia in patients with severe COPD. Intraoperative shoulder tip or abdominal pain does not seem to be a major deterrent and can be effectively controlled with small doses of opioid analgesia.

Clinical Trial
Laparoscopic Collis gastroplasty and Nissen fundoplication. A new technique for the management of esophageal foreshortening.
The short esophagus increases the difficulty and limits the effectiveness of laparoscopic Nissen fundoplication. In out experience, approximately 20-25% of esophagi judged by preoperative criteria to be foreshortened will, after dissection, be insufficiently long to allow 2 cm of esophagus to reside below the diaphragm without inferior distraction (i.e., tension free). Collis gastroplasty combined with Nissen fundoplication has become the standard approach for the creation of an intraabdominal neoesophagus and fundic wrap. ⋯ The management of patients with esophageal foreshortening is a complex problem. We believe that our technique of laparoscopic Collis-Nissen provides an effective means of achieving intraabdominal placement of the fundic wrap while maintaining the benefits of minimally invasive approach.

Comparative Study
A comparison of laparoscopic ultrasound with digital fluorocholangiography for detecting choledocholithiasis during laparoscopic cholecystectomy.
Laparoscopic ultrasound is an alternative to operative cholangiogram for evaluation of the common bile duct (CBD) during laparoscopic cholecystectomy. It is a safe, fast, and reliable method for detecting choledocholithiasis. ⋯ LUS is a reliable alternative to DFCG during laparoscopic cholecystectomy (LC). With experience, it is as sensitive as DFCG and more specific. It is more rapidly performed than cholangiography.

Laparoscopic appendectomy is an acceptable alternative for the treatment of perforated appendicitis.
Ever since laparoscopy was first applied to the treatment of appendicitis, a controversy has existed as to whether the acknowledged benefits of a minimally invasive approach warrant its preference over the conventional treatment, which historically has had relatively low morbidity. The purpose of this study was to determine if laparoscopic appendectomy should be performed preferentially in cases where surgeons are not limited by technical constraints. ⋯ Our data suggest that most cases of acute appendicitis with suspected perforation could be managed laparoscopically. Laparoscopic appendectomy significantly reduces length of stay and hospital costs in patients with perforated appendicitis.
