Laparoscopic cholecystectomy has been recognized since 1992 as the gold standard procedure for gallbladder surgery. The authors propose a single-incision laparoscopic (SILS) cholecystectomy as a step toward less invasive surgical procedures. A single intraumbilical 12-mm incision is made, and the umbilicus is pulled out, exposing the fascia. Pneumoperitoneum is induced with the Versastep Veress access needle. A 5-mm trocar then is introduced, and the abdominal cavity is explored with a 5-mm 30 degrees optic. Second and third trocars are introduced respectively at the left and right sides, near the first trocar. Two sutures are used to suspend the gallbladder and to ensure optimal exposure of the Triangle of Calot. Dissection is performed as a normal retrograde cholecystectomy using an Endoshear roticulator in the left trocar and an Endograsp roticulator in the right hand. The cystic artery and cystic duct are clipped separately with a standard 5-mm clip applier and then excised. The gallbladder is removed through the umbilical incision. Of the 12 patients who underwent SILS cholecystectomy without major complications, 8 had previously undergone other laparoscopic surgeries. The body mass index (BMI) exceeded 35 in three cases. Operative time decreased and stabilized from the first 3-h SILS cholecystectomy to approximately 50 min after the first five cases. At this writing, the authors find SILS cholecystectomy to be feasible, safe, and effective.

Single-incision laparoscopic surgery has been developed with the aims of further reducing the invasiveness of traditional laparoscopy. The technique of lap-band placement from a single intraumbilical incision is described. Three patients underwent a single-incision laparoscopic surgery gastric banding (SILS-GB) for morbid obesity from May to September 2008. All interventions were uneventful and patients were discharged on first postoperative day, after an upper gastrointestinal series. SILS-GB is virtually scarless intervention and may be performed as a day-surgery procedure for the treatment of morbid obesity.

Emerging technology has contributed to the diffusion of SILS; single-incision laparoscopy is validated and established in cholecystectomy and is gaining acceptance in other techniques also. High technical skill is required for manipulating, measuring, and suturing the bowel with articulated instruments. However, randomized, controlled trials are required to determine the real advantages of this technique in comparison with standard laparoscopy.

Therapeutic biliary endoscopy after biliopancreatic diversion (BPD) for morbid obesity is not possible through the anatomical route. In the case of a long excluded afferent limb, the possibility to reach endoscopically the papilla through a surgical gastrostomy or jejunostomy has been reported. A case of laparoscopy-assisted ERCP performed 4 years after laparoscopic BPD with distal gastrectomy, is reported. Access to the papilla was obtained laparoscopically by enterotomy, insertion of a trocar into a jejunal loop 40 cm distal to the ligament of Treitz and passage of the duodenoscope through the trocar to the papilla. A guidewire was laparoscopically advanced into the cystic duct, and bile duct cannulation was achieved using the rendez-vous technique; endoscopic sphincterotomy and extraction of stones were successful. Laparoscopic cholecystectomy was performed and the enterotomy was sutured. The clinical course was uneventful.
