Laparoscopic Heller procedure for achalasia
This is a 'live' surgery performed by Dr. B Dallemagne demonstrating the key steps in performing a Heller procedure. Minimal dissection is carried out to expose the anterior surface of the esophagus, after which the myotomy is delicately performed with scissors. This video is recommended to upper GI surgeons.
Barium swallow showed the classic sign of achalasia at the level of the cardia in this elderly woman with gastroesophageal reflux disease. CT-scan of the chest showed a large sigmoid-like esophagus. Mobilization of the esophagus begins with the authors opening only the anterior aspect of the hiatus to gain access to the esophagus. They dissect the upper part of the esophagus and expose the azygos vein on the right, clearing the gastroesophageal junction on the gastric side of the cardia. They continue by opening the hypertrophic musculature to enable swallowing, then continue with a Heller myotomy.

Micro-instrumentation for minimally invasive cholecystectomy: surgical technique
This video demonstrates an esthetic cholecystectomy using 2mm micro-instruments. The key steps and difficulties of this procedure are shown in detail by Professor Didier Mutter. This video is recommended to general surgeons.
The authors use 2mm micro-instruments in this 25-year-old woman with symptomatic cholelithiasis. They dissect in the avascular plane between Glisson’s capsule and the gallbladder. Dissection with the micro-instruments is more time-consuming than with conventional instruments because the 2mm instruments have two drawbacks: flexibility, and being situated inside the abdomen with little of the instrument on the outside. After the dissection, the authors remove the 2 cameras and introduce the extraction bag through the umbilicus. They then reinsert the 10mm camera to check the operative field and help guide removal of the trocars. This step helps to minimize postoperative hemorrhage. Cosmesis is enhanced with three 2mm incisions and one 10mm incision deep in the umbilicus.

Laparoscopic resection of the 3rd and 4th portion of duodenum for a gastrointestinal stromal tumor (GIST)
This video demonstrates the rather difficult procedure of laparoscopic resection of the distal duodenum. The duodenum is dissected from both above and below the transverse mesocolon. A hand-sewn duodenojejunal anastomosis restores bowel continuity. This video is recommended for upper GI surgeons.
The patient is in the dorsal position with arms outstretched and legs abducted. The surgeon stands between the patient’s legs. Mobilization begins with adhesiolysis and then moves onto dissection of the duodenum with a Kocher's maneuver. The author completely mobilizes the third portion of duodenum. Once the surgeon identifies the third and fourth portions of the duodenum, ultrasound helps define the resection margins, initially marked with metallic clips. The procedure continues with division of the ligament of Treitz and resection of the first jejunal loop with a vascular stapler.
