Review Comparative StudyAppendicitis: laparoscopic versus conventional operation: a study and review of the literature.
A retrospective study was performed after introduction of the laparoscopic technique in patients with suspected appendicitis to validate it in comparison with conventional open appendectomy. A series of 103 patients with suspected acute appendicitis were included. In 51 consecutive patients, a diagnostic laparoscopy was performed, and, if needed, an appendectomy was carried out. ⋯ The postoperative need for analgesia was lower (p < 0.01) and the operation time was longer (p < 0.0001) in the laparoscopic group than the group that underwent open surgery. It can be concluded that the greatest benefits of the laparoscopic technique are that it causes less trauma, the diagnostic accuracy is better, and the cosmetic result is superior to that after a conventional operation. This is all at the price of a longer operation time.

Review Case ReportsClinical manifestations of lost gallstones after laparoscopic cholecystectomy: a case report with review of the literature.
Laparoscopic cholecystectomy has become the preferred treatment for patients with symptomatic gallstones. During this procedure, perforation of the gallbladder with spillage of stones into the peritoneal cavity is not uncommon. Finding and removing all of the spilled gallstones can be laborious and is often avoided. ⋯ We report here on a patient with an intraperitoneal abscess located between the right liver lobe and the anterior abdominal wall, which contained a large gallstone (4 cm3), found 3 months after an undetected stone spillage during laparoscopic cholecystectomy. Healing was achieved after conventional laparotomy, removal of the gallstone, and surgical drainage of the abscess cavity. The review of the literature emphasizes the clinical manifestations of this rare laparoscopic complication.

Review Comparative StudyLaparoscopic cholecystectomy in obese patients compared with nonobese patients.
Obese patients treated by laparoscopic cholecystectomy currently appear to be the largest risk subgroup amenable to consistent scientific evaluation. Here we report our experience and compare the results in obese patients with those obtained in nonobese patients undergoing the laparoscopic procedure. ⋯ Obese patients present significant anesthesiological complications (p < or = 0.001). The results of this experience and the literature review indicate that the therapeutic advantages proved in nonobese patients can be extended to the obese population.

Review Case ReportsExtensive subcutaneous emphysema and hypercapnia during laparoscopic cholecystectomy: two case reports.
We report two cases of marked hypercapnia of more than 60 mm Hg (PaCO2) and extensive subcutaneous emphysema noted during laparoscopic cholecystectomy. The first case, a 55-year-old man was diagnosed as having cholecystolithiasis and had hypercapnia up to 83.5 mm Hg (PaCO2) during laparoscopic cholecystectomy. The patient resumed spontaneous respiration under controlled ventilation accompanied by persistent bigeminal pulse. ⋯ Mild hypercapnia during pneumoperitoneum of about 50 mm Hg (PaCO2) has been reported previously. As compared with cases in the literature, the present cases suggest that hypercapnia is due to extensive subcutaneous emphysema. The large absorption surface area in the subcutaneous tissue and the large difference in the partial pressure cause the extensive gaseous interchange of CO2 between subcutaneous tissue and blood perfusing into it at the moment between peritoneal cavity and blood perfused the peritoneum.
