Gallbladder absence is an infrequent anomaly normally accompanied by lack of the cystic duct. Of unknown etiology, in general it is accepted to be a congenital malformation. A male patient (age 59) diagnosed with nonfunctional symptomatic scleroatrophic gallbladder by echography and ERCP was operated on using a laparoscopic approach. Gallbladder and cystic absence was diagnosed during the procedure. A new case of gallbladder and cystic duct absence, diagnosed by laparoscopy, is presented. This type of extrahepatic bile duct malformation is quite rare, but it must be taken into account due to the generalization of laparoscopic surgery in biliar pathology because of the high risk of serious lesions to the hepatocholedochal system.

The appearance of fistulas and the posterior intragastric inclusion of the adjustable silicone Lap-Band prothesis have been described, representing a severe complication of the Lap-Band procedure. A 45-year-old patient with severe obesity, weighing 115 kg, and having BMI (body max index) of 45 kg/m2 was assigned to a protocol to place a Lab-Band in her. An infection in the reservoir after 9 months indicated the beginning of the appearance of fistulas. The entire adjustable silicone gastric band device eroded inside the stomach between months 9 and 14 after its placement, resulting in reoperation. The gastric inclusion of the Lap-Band device represents a severe complication that requires reoperation, and raises concerns about the safety of this new alternative weight reduction operation.

Total LA performed with UAS is feasible. Use of the UAS may make dissection and resection of the appendix easier, helping to reduce the mean operative time.
