Risk factors for pain after Frey's procedure in chronic pancreatitis
Pancreatic pain is the most frequent symptom of chronic pancreatitis (CP) and is difficult to treat. This retrospective study aimed to determine the risk factors for pain in CP.
From January 2009 and March 2014, 75 consecutive patients with CP who underwent Frey's procedure were reviewed for this study. According to Izbicki pain scores, these patients were divided into 2 groups: (1) pain (Izbicki pain score of >10 after a decrease of >50%) and (2) pain-free (Izbicki pain score of ≤10). Demographic data, medical history, postoperative variables, and follow-up evaluations of the patients were documented.
The postoperative pain score (11.8) was significantly lower than the preoperative score (51.8) after a median follow-up of 4.2 years. Alcoholism (odds ratio [OR] 7.767, P = .002) and preoperative analgesic medication use (OR 4.113, P = .030) were independent risk factors for pain.
Frey's procedure is an effective operation for pain relief in patients with CP. Alcoholism and preoperative analgesic medication use were 2 factors for failure to achieve complete pain relief.
