Objective:
To explore the feasibility and safety of type II binding pancreaticogastrostomy (BPG) in pancreaticoduodenectomy and mid-segmentectomy of pancreas.
Methods:
From November 2008 to May 2009, 26 patients underwent pancreaticoduodenectomy and mid-segmentectomy of pancreas with type II BPG reconstruction, including 13 cases of pancreatic head cancer, 3 cases of duodenal adenocarcinoma, 2 cases of ampullary carcinoma, 4 cases of cholangiocarcinoma, 1 case of bile duct cell severe atypical hyperplasia, and 1 case of stomach cancer. The process of type II BPG was described as the following: after pancreas remnant was mobilized for 2-3 cm, a piece of sero-muscular layer at the posterior gastric wall was excised and then a sero-muscular depth purse-suturing with 3-0 prolene was pre-placed (outer purse-string). Incising anterior gastric wall or opening part of the closed distal gastric stump, the mucosa layer at the sero-muscular defect was incised and then purse-suture at the mucosal tube was pre-placed (inner purse-string). Through the two pre-placed purse-strings, the pancreas remnant was pulled into the gastric lumen and then posterior gastric wall was pushed backward to keep it closely in contact with the retro-peritoneal wall. Thereafter, the outer purse-string was tied (outer binding) and then the inner purse-string was tied (inner binding).
Results:
All cases underwent BPG of type II. The operative time ranged from 3 to 5.5 hours. The postoperative hospital stay ranged from 6 to 48 days. Postoperative complications included 1 case of ascites, 2 cases of delayed gastric emptying and 1 case of intra-abdominal bleeding. All cases with complications were cured after nonsurgical treatment. No mortality or pancreatic leakage occurred.
Conclusions:
Pancreaticogastrostomy is good for accommodating a large pancreas stump. Binding technique is very helpful in minimizing the leak rate of pancreaticogastrostomy. While type I BPG is safe and easy to perform, type II is even safer and easier to be done.
