No significant persistent symptoms from gallstones left in the abdomen after cholecystectomy.

INTRODUCTION: Perforation of the gallbladder during cholecystectomy can lead to spillage of gallstones. The aim of this study was to examine if patients with gallstones left in the abdomen after cholecystectomy suffer persisting symptoms. METHOD: This study was based on data from the Swedish Register for Gallstone Surgery. Patients with intraoperative gallbladder perforation where it is suspected that gallstones remain in the abdomen were matched with patients that had undergone a cholecystectomy with no suspicion of spilled gallstones. All patients were sent a validated questionnaire including 21 items concerning abdominal pain and inflammatory symptoms. Items were divided into four groups: abdominal pain, consequences of pain, gastrointestinal symptoms, and repeated operation. Mean scores were compared between the study group and the control group using a linear regression model. RESULTS: The questionnaire was sent to 4269 subjects, and the response rate was 66 %. No significant differences were seen between the study and control groups in the four domains. In the repeated operation domain, 7.1 % in the study group and 5.3 % in the control group underwent a repeated operation (p = 0.057). CONCLUSION: Gallstones left in the abdomen are not associated with long-term symptoms. There was a tendency towards a repeat operation in the group that suffered perforation of the gallbladder, although this finding was not significant.

Safety of cholecystectomy performed by surgeons who prefer fundus first versus surgeons who prefer a standard laparoscopic approach.

Background: An alternative method to standard laparoscopic cholecystectomy (SLC) is the "fundus first" method (FFLC). Concerns have been raised that FFLC can lead to misinterpretation of important anatomical structures, thus causing complications of a more serious kind than SLC. Comparisons between the methods are complicated by the fact that FFLC is often used as a rescue procedure in complicated cases. To avoid confounding related to this we conducted a population-based study with comparisons on the surgeon level. Method: In GallRiks, the Swedish registry for Gallbladder surgery, we stratified all cholecystectomies performed 2006-2020 in three groups: surgeries carried out by surgeons that uses FFLC in <20 % of the cases (N = 150,119), in 20-79 % of the cases (N = 10,212) and in 80 % or more of the cases (N = 3176). We compared the groups with logistic regression, adjusting for sex, age, surgical experience, year of surgery and history of acute cholecystitis. All surgical complications (bleeding, gallbladder perforation, visceral perforation, infection, and bile duct injury) were included as outcome. A separate analysis was done with regards to operation time. Results: No difference in incidence of all surgical complications or bile duct injury were seen between groups. The rates of bleeding (OR 0.34 [0.14-0.86]) and gallbladder perforation (OR 0.61 [0.45-0.82]) were significantly lower in the "fundus first > 80% group" and the operative time was shorter (OR 0.76 [0.69-0.83]). Conclusion: In this study including >160,000 cholecystectomies, both methods was found to be equally safe. Key message: During laparoscopic cholecystectomy, the standard method of dissection and fundus first dissection are equally safe surgical techniques. Surgeons need to learn both methods to be able to use the one most appropriate for each individual case.
