Laparoscopic treatment of pancreatic pseudocysts

Background A multicentric study was performed to evaluate the clinical results after laparoscopic treatment of pancreatic pseudocysts (PP). Methods We collected the data of 17 patients presenting with PP and operated on by laparoscopy between 1996 and 2001. There were nine men and eight women with a median age of 42 years (range 30–72). In 15 patients the PP developed after acute pancreatitis and the median delay between the acute onset and surgery was 7 months (range: 2–24). In two patients the PP was associated with chronic pancreatitis. All the patients has a single PP with a median diameter of 9 cm (range: 5–20). Results According to the location of the PP, a cystogastrostomy was performed in 10 patients and a cystojejunostomy in seven patients. The median operative time was 100 min (range: 80–300). Laparoscopic PP surgery was completed suscessfully in 16 patients and the median size of the cystoenterostomy was 3 cm (range: 2–5). Necrotic debris was present within the PP in 11 patients. The median, postoperative hospital stay way 6 days (range: 4–24). No mortality and no immediate morbidity were recorded. However, two patients were readmitted within the first 3 postoperative weeks because of secondary PP infection. The first patient had an early closure of cystograstrostomy and was treated by endoscopic placement of a stent. The second represented with a right retrocolic abscess after cystojejunostomy and was treated by percutaneous drainage. One patient was lost for follow-up 2 months after surgery. The others had regular clinical and radiological controls. With a median follow-up of 12 months (range: 6–36), no recurrence of PP was observed. Conclusions The laparoscopic treatment of PP was associated with a low postoperative complication rate and an effective permanent result. That approach avoided some difficulties, particularly bleeding that is classically linked with endoscopic internal drainage.
