title: Laparoscopic pancreatic cystgastrostomy.
abstract: Internal drainage of acute pancreatic pseudocysts is indicated 6 weeks after the first documentation of pseudocyst. It is also indicated for symptomatic chronic pseudocysts 6 cm or more in diameter. When pseudocysts are located in close contact with the posterior wall of the stomach, they are best drained by pseudocyst-gastrostomy. This procedure can also be completed making use of intragastric surgical techniques. Under standard laparoscopic observation, three intragastric ports are placed through the abdominal and anterior gastric walls, establishing working channels for a telescope and hand instruments. After the presence of pseudocysts is confirmed, the posterior wall of the stomach and the cyst wall can be incised by electrocautery. After a sufficient drainage orifice is made and the cyst contents are thoroughly debrided, the intragastric ports are removed and defects in the gastric wall are closed with sutures placed via the standard laparoscopic approach. This approach is much less invasive than the conventional approach, which entails a large gastrotomy in the anterior wall of the stomach. This procedure should be the method of choice when interventional radiology or endoscopic intervention fails to effectively drain retrogastric pseudocysts.
