Factors relevant to persistent upper abdominal pain after cholecystectomy

Abstract

BackgroundCholecystectomy is a routine procedure for treatment of upper abdominal pain (UAP) and other atypical symptoms associated with gallstones. UAP, however, persists in some cases postoperatively. The present study was to identify the risk factors relevant to persistent UAP after cholecystectomy. Methods1714 symptomatic patients undergoing cholecystectomy for gallstones were enrolled. All the patients were asked to complete a biliary symptom questionnaire. The risk factors for persistent postcholecystectomy UAP and features related to sustained relief of postcholecystectomy UAP were evaluated. Results172 (10%) patients complained UAP after cholecystectomy. In multivariate analysis, female gender, preoperative UAP occurring >24h before admission, and each episode of UAP >30min were independently associated with persistent postoperative UAP (all p < 0.05). 132 (76.7%) patients reported sustained relief of postcholecystectomy UAP, the causes of which remained unknown but were attributed to functional postcholecystectomy syndrome. Shorter duration of preoperative UAP (occurring within 24 h before admission), less frequency of postoperative UAP (≤1 episode per day) and administration of choleretic medications were independently associated with postoperative UAP relief (all p < 0.05). ConclusionFemales with longer historical and more frequent preoperative UAP are more likely to develop postcholecystectomy UAP. Choleretic medications are effective in relieving postoperative UAP.
