Preoperative factors associated with technical difficulties of laparoscopic cholecystectomy in acute cholecystitis

Risk Factors and Prevalence Associated With Conversion of Laparoscopic Cholecystectomy to Open Cholecystectomy: A Tertiary Care Hospital Experience in Western Mexico

Introduction Laparoscopic cholecystectomy (LC) is a common procedure used for the treatment of different pathologies caused by gallstones in the gallbladder, and one of the most common indications is acute cholecystitis. The definitive treatment for acute cholecystitis is surgery, and LC is the gold standard. Nevertheless, transoperative complications (like intraoperative bleeding, anatomical abnormalities of the gallbladder, etc.) of LC and some other preoperative factors (like dilatation of bile duct, increased gallbladder wall thickness, etc.) can cause or be a risk factor for conversion to open cholecystectomy (OC). The objective of this study was to determine the risk factors and prevalence associated with the conversion from LC to OC in patients with gallbladder pathology and the indication for LC. Materials and methods This was a prospective cohort study. We included patients of both sexes over 18 years of age with gallbladder disease. To determine the risk factors associated with conversion, we performed a bivariate analysis and then a multivariate analysis. Results The rate of conversion to OC was 4.54%. The preoperative factors associated with conversion, in the bivariate analysis, were common bile duct dilatation (p=0.008), emergency surgery (p=0.014), and smoking (p=0.001); the associated intraoperative variables were: laparoscopic surgery duration (p <0.0001), Calot triangle edema (p=0.033), incapacity to hold the gallbladder with atraumatic laparoscopic tweezers (p=0.036), and choledocholithiasis (p=0.042). Laparoscopic Surgery duration was the only factor with a significant association in the multivariate analysis (p=0.0036); we performed a receiver operating characteristic (ROC) curve analysis and found a cut-off point of 120 minutes for the duration of laparoscopic surgery with a sensitivity and a specificity of 67 and 88%, respectively. Conclusion The prevalence of conversion from LC to OC is similar to that reported in the international literature. The risk factors associated with conversion to OC, in this study, should be confirmed in future clinical studies, in this same population, with a larger sample size.

Comparison of surgical outcomes of emergent laparoscopic cholecystectomy for acute cholecystitis between attending surgeons and senior residents: A propensity-matched analysis

INTRODUCTION

Emergent laparoscopic cholecystectomy (LC) is routinely performed for acute cholecystitis (AC) at our institution. This study was conducted to investigate the feasibility and safety of emergent LC for AC performed by senior residents.

MATERIALS AND METHODS

Data from 362 patients with AC who underwent emergent LC between January 2012 and June 2020 were retrospectively reviewed. Of these patients, 328 were operated on by senior residents (SR), and 34 were operated on by the attending surgeon (AS). Clinical characteristics and surgical and postoperative outcomes were compared between the SR and AS groups. Propensity score matching was used to minimize selection bias. When the operator was an SR, the LC was assisted by the AS.

RESULTS

Before matching, in the SR group, more patients had a history of abdominal surgery, and C-reactive protein and white blood cell counts were significantly higher. In the image findings, the minor axis of the gallbladder (GB) was longer, and the wall of the GB was thicker in the SR group. After propensity score matching, 28 pairs were identified. There were no significant differences in operative time (83 vs 88 minutes, P = .92), the amount of blood loss (25 vs 10 mL, P = .13), conversion to open surgery (3.6% vs 3.6%, P = 1), postoperative complications (7.2% vs 0%, P = .74), and postoperative hospital stay (4 vs 4 days, P = .87).

CONCLUSION

Emergent LC for AC performed by SR under supervision appears to be feasible and safe.

Preoperative risk factors for technical difficulty in emergent laparoscopic cholecystectomy for acute cholecystitis

AIM

We have routinely performed emergent laparoscopic cholecystectomy (LC) as soon as we diagnosed acute cholecystitis (AC), if patients could tolerate surgery. This study was conducted to identify the preoperative risk factors that predict the technical difficulty of emergent LC for AC.

METHODS

A retrospective review of patients with AC who underwent emergent LC between 2012 and 2019 was conducted. Technical difficulty was defined as the presence of the following conditions: open conversion, operative time ≥120 min, or blood loss ≥500 ml.

RESULTS

In all, 327 patients were included and divided into difficult LC (DLC, n = 61) and nondifficult LC (non-DLC, n = 266). Multivariate logistic analysis revealed that symptom duration ≥72 h was the only independent risk factor for DLC. Comparison of late LC (beyond 72 h, LLC) and early LC (within 72 h, ELC) showed a lower rate of creation of the critical view of safety and a longer hospital stay, as well as a longer operative time, a larger amount of bleeding, and a higher open conversion rate in LLC. However, the postoperative complication rates were equivalent.

CONCLUSION

LC for AC with symptom duration ≥72 h tends to be technically difficult. However, it is acceptable regarding operative outcomes.

Laparoscopic cholecystectomy in patients with liver cirrhosis: 8 years experience in a tertiary center. A retrospective cohort study

With improved laparoscopic techniques, experience, and availability of newer tools and instruments like ultrasonic shears; laparoscopic cholecystectomy (LC) became a feasible option in cirrhotic patients, the aim of this study was to analyze the outcome of LC in cirrhotic patients.

METHODS

We retrospectively analyzed 213 cirrhotic patients underwent LC, in the period from 2011 to 2019; the overall male/female ratio was 114/99.

RESULTS

The most frequent Child-Turcotte-Pugh (CTP) score was A, The most frequent cause of cirrhosis was hepatitis C virus (HCV), while biliary colic was the most frequent presentation. The harmonic device was used in 39.9% of patients, with a significant correlation between it and lower operative bleeding, lower blood and plasma transfusion rates, higher operative adhesions rates, lower conversion to open surgery and 30-day complication rates, shorter operative time and post-operative hospital stays where operative adhesions and times were independently correlated. The 30-day morbidity and mortality were 22.1% and 2.3% respectively while overall survival was 91.5%, higher CTP, and model for end-stage liver disease (MELD) scores, higher mean international normalization ratio (INR) value, lower mean platelet count, higher operative bleeding, higher blood, and plasma transfusion rates, longer mean operative time and postoperative hospital stays were significantly correlated with all conversion to open surgery, 30-day morbidities and mortalities.

CONCLUSION

LC can be safely performed in cirrhotic patients. However, higher CTP and MELD scores, operative bleeding, more blood and plasma transfusion units, longer operative time, lower platelet count, and higher INR values are predictors of poor outcome that can be improved by proper patient selection and meticulous peri-operative care and by using Harmonic scalpel shears.
