Insights
Thalassaemia patients with gallstones face significantly higher perioperative complications and mortality after cholecystectomy compared to non-thalassaemics. This suggests a need to reconsider current policies regarding elective gallbladder removal in thalassaemia patients.
Area of Science:
- Hepatobiliary surgery
- Hematology
- Surgical outcomes
Background:
- Cholecystectomy for gallstones in thalassaemia patients is typically reserved for symptomatic cases.
- Current practice rarely involves elective cholecystectomy, even when combined with splenectomy.
Purpose of the Study:
- To evaluate if thalassaemia patients experience increased perioperative complications from cholecystectomy for gallstones compared to non-thalassaemic individuals.
- To determine if findings warrant a policy change towards elective cholecystectomy in thalassaemia patients.
Main Methods:
- Retrospective analysis of medical records from 540 thalassaemia patients and 62 non-thalassaemic controls with gallstones.
- Comparison of perioperative complication rates between the two groups following cholecystectomy.
Main Results:
- Significantly higher rates of early and late postoperative complications were observed in thalassaemia patients.
- Six deaths occurred in the thalassaemia group due to sepsis post-cholecystitis, versus none in the control group.
- Most cholecystectomies in both groups were performed after acute cholecystitis attacks.
Conclusions:
- Thalassaemia patients have a substantially higher risk of severe complications and mortality after cholecystectomy for gallstones.
- The increased perioperative risk in thalassaemia patients supports reconsidering the current policy on elective cholecystectomy.
Objective:
At present, cholecystectomy is carried out for thalassaemia patients with gall stone disease only if they develop symptoms of cholecystitis, except in the rare instance where an un-inflammed gall bladder is removed simultaneously with splenectomy. We carried out this retrospective analysis of case records to examine if patients with thalassaemia have a higher rate of peri operative complications compared to non-thalassaemics with gall stone disease, warranting a change of policy to justify elective cholecystectomy.
Results:
Case records of 540 patients with thalassaemia were retrospectively analysed of which 98 were found to have gallstones. Records of 62 patients without thalassaemia with gall stone disease too were used for comparison. 19 of patients with thalassaemia and 52 of non-thalassaemic who had gallstones had undergone cholecystectomy. In all but 5 patients with thalassaemia cholecystectomy was done following attacks of acute cholecystitis as was the case in the non-thalassaemic controls. A significantly higher proportion of early and late complications had occurred in thalassaemia patients compared to non-thalassaemic patients post operatively. Six deaths related to sepsis following acute cholecystitis in the peri operative period were reported among 19 thalassaemia patients whereas no deaths were reported among 55 non-thalassaemic patients who underwent cholecystectomy for gallstones.
