Is cholecystectomy effective treatment for symptomatic gallstones? Clinical outcome after long-term follow-up
1University Department of Surgery, St George's Hospital Medical School, London.
Insights
Cholecystectomy (gallbladder removal) effectively relieves many gastrointestinal symptoms like nausea and vomiting in patients with symptomatic gallstones. However, abdominal pain persists in some, and predicting pain-free outcomes remains challenging.
Area of Science:
- Gastroenterology
- Surgical Outcomes
- Gallstone Disease Management
Background:
- Cholecystectomy is a common surgical procedure for symptomatic gallstones.
- Patient outcomes regarding symptom relief after cholecystectomy can vary.
- Predicting long-term pain-free outcomes requires further investigation.
Purpose of the Study:
- To evaluate the impact of cholecystectomy on gastrointestinal symptoms in patients with symptomatic gallstones.
- To identify factors associated with successful pain-free outcomes post-surgery.
- To assess the effectiveness of cholecystectomy in improving specific gastrointestinal symptoms.
Main Methods:
- A cohort of 92 patients undergoing cholecystectomy for symptomatic gallstones was followed for a mean of 31.1 months.
- Preoperative clinical data, ultrasound findings, and postoperative symptoms were analyzed.
- Statistical methods including logistic regression and outcome benefit ratios were employed.
Main Results:
- Abdominal pain persisted or recurred in 30.4% of patients.
- Pain-free outcomes were associated with preoperative biliary colic, fatty food intolerance, and a thick-walled gallbladder.
- Significant improvements were observed in bloating, dyspepsia, heartburn, fat intolerance, nausea, and vomiting.
- Diarrhea, constipation, and excessive flatus were not significantly improved.
- Outcome benefit ratios indicated substantial relief for vomiting, nausea, dyspepsia, fat intolerance, and heartburn.
Conclusions:
- Cholecystectomy provides significant relief for several gastrointestinal symptoms associated with gallstones, supporting its role as a gold standard treatment.
- While effective for many symptoms, predicting long-term pain-free outcomes remains difficult.
- Factors like gallbladder wall thickness and specific preoperative symptoms may indicate better surgical results.
Abstract:
The expectation that cholecystectomy is effective treatment for symptomatic gallstones is not always achieved in surgical practice. The impact of cholecystectomy on the relief of gastrointestinal symptoms was evaluated in 92 patients followed up after surgery for a mean of 31.1 months (range 12-83 months). Abdominal pain continued to be present, or arose de novo, in 28 (30.4%) patients. Pain-free outcome after cholecystectomy was associated with a preoperative clinical diagnosis of biliary colic, fatty food intolerance, and a thick-walled gallbladder on ultrasound (P = 0.02). Logistic regression associated a thick-walled gallbladder, elevated gamma-glutamyl transpetidase, body mass index < 26, fat intolerance, and normal bowel habit with good postoperative results (P = 0.001). Application of each of these five factors to a clinical index failed to predict long-term pain-free outcome after cholecystectomy. Abdominal bloating (P = 0.03), dyspepsia (P < 0.001), heartburn (P < 0.007), fat intolerance (P < 0.001), nausea (P = 0.001) and vomiting (P < 0.001) were significantly improved after cholecystectomy, but diarrhoea, constipation and excessive flatus were not. Outcome benefit ratios confirmed that vomiting (0.96), nausea (0.87), dyspepsia (0.67), fat intolerance (0.57) and heartburn (0.51) were relieved by surgery. Cholecystectomy improved symptoms compared with a matched control group, suggesting that surgery remains the gold standard treatment of symptomatic gallstones.
