Pancreatic fistula after pancreaticoduodenectomy: a comparison between patients with periampullary tumors and chronic pancreatitis.

BACKGROUND/AIMS: Whether the frequency of anastomotic leak after pancreaticoduodenectomy for benign diseases is greater than for malignant conditions and whether fistula development is associated with surgical mortality remains controversial. The purpose of this study is to compare the incidence of anastomotic leak in patients operated on for chronic pancreatitis and periampullary tumors.

METHODOLOGY

The authors retrospectively reviewed the charts of 67 patients (46 males, 21 females, mean age 47 years) submitted to pancreaticoduodenectomy for chronic pancreatitis and periampullary tumors between 1990 and 1996.

RESULTS

In 44 patients with periampullary cancers, pancreatic fistula developed in 13 (29%) cases, and in 6 (26%) of the 23 patients with chronic pancreatitis (p>0.05). Of the 19 patients who developed this complication, 5 (26.3%) died, and in the remaining 48 cases, there was only one (2.1%) death (p<0.05).

CONCLUSION

The frequency of pancreatic fistula after pancreaticoduodenectomy in patients with periampullary tumors and chronic pancreatitis is not different, but the presence of a fistula is strongly involved in postoperative mortality.
