Comparative Study
Comparison of laparoscopic, open, and converted appendectomy for perforated appendicitis.
Perforated appendicitis is associated with a significant risk of postoperative abdominal and wound infection. Only a few controversial studies evaluate the role of laparoscopy in perforated appendicitis. The significance of conversion from laparoscopy to open appendectomy for perforated appendicitis is not well defined. Statistical analysis was performed using Student's t-test. ⋯ No difference in the rate of postoperative intra-abdominal abscesses exists between laparoscopic and open appendectomy for perforated appendicitis. Wound infections and ileus complicate the postoperative course of patients after laparoscopic appendectomy less frequently than after open appendectomy. The conversion of laparoscopic to open appendectomy for perforated appendicitis is associated with increased postoperative morbidity.

A 36-year-old woman was admitted to the hospital for an abdominal blunt trauma. At ultrasound (US) and computed tomography (CT), a gallbladder lesion was suspected, along with a tear of the liver. The patient was submitted to a diagnostic laparoscopy. ⋯ It should be accompanied by a cystic duct cholangiography and a Kocher's maneuver to evaluate the integrity of the biliary tree. Laparoscopic cholecystectomy is generally feasible. Associated lesions require laparotomy when they are not amenable to laparoscopic treatment.

Delay in the diagnosis of intraabdominal pathology is a major contributor to the morbidity and mortality of intensive care unit (ICU) patients. Laparoscopy is a valuable diagnostic tool that can be used safely and efficiently in the evaluation of intraabdominal processes that may be difficult to diagnose with conventional methods. Our goal was to show that laparoscopy performed at the bedside in the ICU could be used as a routine diagnostic tool in the evaluation of critically ill patients, just as computed tomography (CT), ultrasonography (US), and radiography are. ⋯ We conclude that bedside laparoscopy in the ICU under local anesthesia is a diagnostic and potentially therapeutic tool that can be used safely in the work-up of potential abdominal pathology in critically ill patients.

Comparative Study
Outcomes of laparoscopic fundoplication for gastroesophageal reflux disease and paraesophageal hernia.
Laparoscopic fundoplication has become the standard for operative treatment of gastroesophageal reflux disease (GERD). ⋯ The average length of hospitalization was 2.2 days, and 136 patients stayed longer than 2 days. Major complications occurred in 21 patients: esophageal perforation (n= 10), acute paraesophageal herniation (n = 4), splenic bleeding (n = 2), cardiac arrest (n = 1), pneumonia (n = 3), and testicular abscess (n = 1). Additional operations were required to manage the complications in 14 patients (70%): Four of these procedures were performed emergently, and 10 patients underwent reoperation between 6 h and 10 days. There were three deaths, all of which involved elderly patients with paraesophageal hernia. There were 35 late failures requiring reoperation for recurrence of GERD or development of new symptoms: The treatment of 32 patients was revised laparoscopically, and 4 patients required laparotomy. Beyond 1 year (median follow-up period, 27 months), 94% of the reviewed patients were satisfied with their surgical outcome.

As new techniques are emerging for laparoscopic liver resections, concerns have been raised about the development of gas embolus related to the CO(2) pneumoperitoneum. We hypothesized that elevated intrahepatic vascular pressures and decreased hepatic tissue blood flow (LQB) would prevent gas embolus during laparoscopic liver resections under conventional pneumoperitoneum. ⋯ These data suggest that the risk of significant embolus under conventional pneumoperitoneum is minimal during laparoscopic liver resections.
