Laparoscopic intragastric stapled cystogastrostomy for pancreatic pseudocyst

Background: Mature symptomatic pancreatic pseudocysts require surgical intervention for their management. In this era of minimal access surgery, several reports are now available of laparoscopic management of pancreatic pseudocysts. Patients and Methods: We have performed this procedure in five patients over the past 2 years. Four patients developed the pseudocyst after acute alcoholic pancreatitis and one following acute biliary pancreatitis. The diameter of the pseudocyst ranged from 8 to 12 cm. The procedure was performed using five ports. The Harmonic Scalpel was used to create two ports in the anterior stomach wall through which two balloon trocars were placed into the gastric lumen. Following balloon inflation, the trocars were used to lift up the anterior gastric wall. This created the space for the cystogastrostomy to be fashioned laparoscopically through the balloon trocar. The ball probe of the Harmonic Scalpel was used to puncture the cyst through the posterior gastric wall. The cystogastrostomy was completed by firing an Endo-GIA30 stapler across the fused posterior gastric wall and anterior wall of the cyst. Results: The mean operative time was 90 minutes (range 80-125 minutes). The mean postoperative stay was 3.0 days. One patient had intraoperative bleeding at the anastomotic site, which was easily controlled. Conclusion: Laparoscopic cystogastrostomy offers a feasible and safe therapeutic option for selected patients with large symptomatic pancreatic pseudocysts.
