Abstract

BACKGROUND: Pancreaticoduodenectomy is well established in the armamentarium of the surgeon treating periampullary carcinoma and benign lesion. With refinement of operative technique and more enlighting management during the postoperative period, the morbidity and mortality of this procedure have reduced significantly. Leakage of the pancreaticojejunal anastomosis has been a major complication after this procedure, frequently reported in an incidence of 5 percent to 15 percent. Therefore, authors retrospectivly reviewed about clinical experience of duct-to-mucosa anastomosis and PTBD in pancreaticoduodenectomy. OBJECTS & METHODS: The authors retrospectively reviewed the medical records of 93 patients who had undergone a pancreaticoduodenectomy with the duct-to-mucosa method between 1994 and 2000 by one surgeon.
RESULTS
The male-to female ratio was 2.1:1(63:30) and mean age was 57 years old(range from 26 to 77). Thirty patients(32.6%) of 93 patients were distal common bile duct cancer, 22 patients(24%) were pancreatic head cancer, 21 patients(23%) were Ampulla of Vater cancer, 5 patients(5.4%) were chronic pancreatitis, 3 patient(3.3%) were duodenal cancer. The operative morbidity was 35.8%, and there was three perioperative mortality(3.2%). The mean operative time was 8.8 hours. A pancreatic fistula was diagnosed in 6 of the 93 patients(6.5%) and surgical intervention was done in 1 of the 6 patients. A PTBD for preoperatively biliary drainage was done 64 cases and complication related PTBD was 3 cases(4.7%, hemobilia).
CONCLUSIONS
Even if this anastomotic technique requires a little more time and attention by the surgeon, we experienced that the low incidence of pancreatico-jejunal anastomosis related complication represents a validation of the method, and a motivation to adapt this anastomotic technique. But, this method is not absolute because surgeon's preference is most important factor in operation.
