Abstract
BACKGROUND: Surgical drainage for chronic pancreatitis patients with a normal-sized pancreatic head remains controversial. Both Frey and extended Partington procedures could be used, but the level of evidence is weak. METHOD: The object of this prospective cohort study was to assess the mid-term results concerning pain, quality of life, and pancreatic function of surgical drainage (Frey or extended Partington procedure) in patients with painful chronic pancreatitis and a normal-sized pancreatic head. RESULTS: Fifty-nine patients (Frey procedure: 14 cases; extended Partington procedure: 45 cases) were enrolled in the study with a median length of follow-up of 16 months. The effective and complete pain relief rate was 85% and 58%, respectively. The Izbicki score decreased from 53.4 preoperatively to 8.8 postoperatively. The general 12-Item Short Form Health Survey (SF-12) score increased from 45.2 to 75.4. The pancreatic insufficiency did not change significantly postoperatively. At three months after surgery, the complete pain relief and Izbicki score were more favorable in the Frey group than in the extended Partington group. CONCLUSION: Both Frey and extended Partington procedures resulted in excellent pain relief and quality of life improvement and did not worsen pancreatic function. The Frey procedure could yield a more favorable result in the early postoperative period.
