Background: Acute appendicitis is the most common emergency in abdominal surgery, but remains a continuing controversy regarding the most appropriate method of removing the inflamed appendix., Materials and Methods: From January 2002 to December 2012, 1037 women underwent appendectomy (average age: 25±15.7 y; range: 6 to 91 y). Of these, 519 underwent open appendectomy (OA) and 518 underwent laparoscopic appendectomy (LA). For all the patients we determined the postoperative hospital stay, the eventual readmissions within 30 days after discharge, the length of surgical procedures (data were available only for the period from January 2008 to December 2012), the costs for the OA and LA, and the rate of negative appendicitis., Results: In our cohort of patients, 189 women (18.2%) had a negative appendectomy. Considering the postoperative hospital stay (average: 4.2±3.6 d; range: 1 to 32 d in OA group and average: 3.9±3.1 d; range: 1 to 21 d in LA group; P=0.15) there were no statistical differences between 2 groups. The average length of surgical procedures in LA group was 42.3±18.4 minutes (range: 8 to 135 min) and 43.2±19 minutes in the OA group (range: 10 to 135 min) (P=0.63). The average net cost of LA was 1203.61 euros, whereas for OA it was 95.18 euros. In this study, we considered only the surgical materials., Conclusions: LAs are not associated with a lower complication rate than the OAs and, above all, LAs are more expensive than OAs. Also we believe that laparoscopic approach should be used only in case of unclear abdominal pain and not for the treatment of clear acute and uncomplicated appendicitis.

Eleven patients underwent choledochoduodenostomy under laparoscopic control: 5 for adenocarcinoma of head of pancreas, including 2 with extension into duodenum, 3 for chronic pancreatitis. 1 for gastric carcinoma with pancreatic infiltration 1 for carcinoma of ampulla and 1 for stenosing papillitis. Mean duration of operation was 97.9 minutes and mean hospital stay 7.8 days. No immediate or delayed postoperative complications were reported. The advantages of this method are the marked reduction in recovery time, especially in severely debilitated elderly patients, and the absence of postoperative pain.

A total of 92 patients were submitted to laparoscopic cholecystectomy during the period Autumn 1990-Spring 1991. The dissection of the gallbladder from the hepatic bed was performed in 40 patients using the Argon beam coagulator, in 25 using the monopolar electrocoagulator and in 27 using the Holmio laser beam. In average, with the Argon beam coagulator time procedure was respectively 2.7 and 5.4 minutes shorter than monopolar electrocoagulator and Holmio laser. Only one complication (pneumomediastinum) was correlated with the use of the Argon beam coagulator.
