Initial experience with endoscopic ultrasound-guided gallbladder drainage

Acute cholecystitis management in high-risk, critically ill, and unfit-for-surgery patients: the Italian Society of Emergency Surgery and Trauma (SICUT) guidelines

Dealing with acute cholecystitis in high-risk, critically ill, and unfit-for-surgery patients is frequent during daily practice and requires complex management. Several procedures exist to postpone and/or prevent surgical intervention in those patients who temporarily or definitively cannot undergo surgery. After a systematic review of the literature, an expert panel from the Italian Society of Emergency Surgery and Trauma (SICUT) discussed the different issues and statements in subsequent rounds. The final version of the statements was discussed during the annual meeting in Rome (September 2022). The present paper presents the definitive conclusions of the discussion. Fifteen statements based on the literature evidence were provided. The statements gave precise indications regarding the decisional process and the management of patients who cannot temporarily or definitively undergo cholecystectomy for acute cholecystitis. Acute cholecystitis management in high-risk, critically ill, and unfit-for-surgery patients should be multidisciplinary. The different gallbladder drainage methods must be tailored according to each patient and based on the expertise of the hospital. Percutaneous gallbladder drainage is recommended as the first choice as a bridge to surgery or in severely physiologically deranged patients. Endoscopic gallbladder drainage (cholecystoduodenostomy and cholecystogastrostomy) is suggested as a second-line alternative especially as a definitive procedure for those patients not amenable to surgical management. Trans-papillary gallbladder drainage is the last option to be reserved only to those unfit for other techniques. Delayed laparoscopic cholecystectomy in patients with percutaneous gallbladder drainage is suggested in all those patients recovering from the conditions that previously discouraged surgical intervention after at least 6 weeks from the gallbladder drainage.

Determinants of outcomes of transmural EUS-guided gallbladder drainage: systematic review with proportion meta-analysis and meta-regression

BACKGROUND AND AIMS

Transmural EUS-guided gallbladder drainage (EUS-GBD) has been increasingly used in the treatment of gallbladder diseases. Aims of the study were to provide a comprehensive meta-analysis and meta-regression of features and outcomes of this procedure.

METHODS

MEDLINE, Scopus, Web of science, and Cochrane databases were searched for literature pertinent to transmural EUS-GBD up to May 2021. Random-effect meta-analysis of proportions and meta-regression of potential modifiers of outcome measures considered were applied. Outcome measures were technical success rate, overall clinical success, and procedure-related adverse events (AEs).

RESULTS

Twenty-seven articles were identified including 1004 patients enrolled between February 2009 and February 2020. Acute cholecystitis was present in 98.7% of cases. Pooled technical success was 98.0% (95% CI 96.3, 99.3; heterogeneity: 23.6%), the overall clinical success was 95.4% (95% CI 92.8, 97.5; heterogeneity: 35.3%), and procedure-related AEs occurred in 14.8% (95% CI 8.8, 21.8; heterogeneity: 82.4%), being stent malfunction/dislodgement the most frequent (3.5%). Procedural-related mortality was 1‰. Meta-regression showed that center experience proxied to > 10 cases/year increased the technical success rate (odds ratio [OR]: 2.84; 95% CI 1.06, 7.59) and the overall clinical success (OR: 3.52; 95% CI 1.33, 9.33). The use of anti-migrating devices also increased the overall clinical success (OR: 2.16; 95% CI 1.07, 4.36) while reducing procedure-related AEs (OR: 0.36; 95% CI 0.14, 0.98).

CONCLUSION

Physicians' experience and anti-migrating devices are the main determinants of main clinical outcomes after EUS-GBD, suggesting that treatment in expert centers would optimize results.

Reconsideration of indications for choledochoscopic gallbladder-preserving surgery and preventive measures for postoperative recurrence of gallstones

Introduction

The recurrence of cholecystolithiasis after choledochoscopic gallbladder-preserving surgery is a major problem. It is unclear whether the recurrence of cholecystolithiasis is due to the limitations of the operation itself or to the selection of inappropriate candidates.

Aim

To analyze the recurrence of cholecystolithiasis after choledochoscopic gallbladder-preserving surgery and to provide guidance for the treatment of cholecystolithiasis by choledochoscopic gallbladder-preserving surgery.

Material and methods

A total of 145 patients who had undergone choledochoscopic gallbladder-preserving surgery were studied from January 2012 to January 2018. The recurrence rate, recurrence time, and risk factors were evaluated.

Results

Of these 145 patients, 14 (9.66%) experienced recurrence with a mean follow-up time of 39.72 ±24.44 months. The mean time to recurrence was 30.07 ±21.21 months. Univariate analysis showed that pregnancy history (p = 0.008), the uniformity of gallstones (p = 0.002), preoperative inflammation (p = 0.022), postoperative oral drugs (p = 0.022) and the regularity of diet (p = 0.001) were significantly related to recurrence. The uniformity of gallstones (odds ratio (OR) = 0.079; 95% confidence interval (CI): 0.010–0.590; p = 0.013) and the regularity of diet (OR = 0.074; 95% CI: 0.010–0.528; p = 0.009) were independent prognostic factors for recurrence according to multivariate analysis.

Conclusions

Nonuniform gallstones combined with an irregular diet are significant risk factors that predict cholecystolithiasis recurrence.

Excision of a part of the bile duct as an iatrogenic injury typical for laparoscopic cholecystectomy - characteristics, treatment and long-term results, based on own material

Introduction

Cholecystectomy is associated with the risk of bile duct injury (BDI). The nature of the injury in laparoscopic cholecystectomy (LC) cases seems to be more serious.

Aim

We present an analysis of long-term results of the treatment of patients who underwent operations at our department due to iatrogenic excision of a part of the bile duct (EPBD).

Material and methods

Out of all 120 patients treated for BDI in our department we selected a group of 40 with EPBD. In all cases the corrective operation was hepaticojejunostomy. The median follow-up time was 157 (56–249) months. We evaluated risk factors for EPBD during LC compared to open cholecystectomy (OC).

Results

Among bile duct injuries referred to our centre, EPBD occurred more frequently during LC (46.7%) compared to OC (11%), p < 0.001. Injuries located in the hepatic hilum occurred more often in the case of LC (68.6%) than OC (20%), p = 0.056. We did not find a difference in the frequency of EPBD between LC and OC groups depending on the presence of acute or chronic cholecystitis. The narrow common hepatic duct was reported more frequently in the LC (68.6%) vs. OC (20%) group, p = 0.056. Satisfactory long-term reconstructive treatment results were observed in 36 (90%) of 40 patients.

Conclusions

Excision of a part of the bile duct occurs more often during LC than OC. It is often located in the hepatic hilum. Presence of a narrow common hepatic duct is a risk factor for EPBD during LC. Large diameter hepaticojejunostomy is a reconstructive procedure that promises good long-term results.

Evaluation of the usefulness of the SAGES Safe Cholecystectomy Program from the viewpoint of the European surgeon

Introduction

Common bile duct injury (CBDI) is a severe complication of laparoscopic cholecystectomy (LC). To minimize its occurrence, SAGES established the Safe Cholecystectomy Program (SCP) with 6 rules to follow during surgery.

Aim

To assess the knowledge of SCP among European surgeons and their opinion on its usefulness.

Material and methods

Data were gathered using questionnaires during surgical conferences in Poland and Denmark. The questionnaire asked about the surgeon’s experience in cholecystectomy and the number of complications in the form of CBDI. It asked about the surgeon’s opinion on the usefulness of SCP rules on a 10-point scale. A comparison between specialists and residents was performed. The study has been registered in the ClinicalTrials.gov – NCT03155321.

Results

One hundred eighty-four questionnaires were gathered. One hundred fourteen (61.96%) specialists (72.8% male, mean age: 50 years) and 70 (38.04%) residents (56% male, mean age: 34 years) completed the questionnaire. Mean work experience was 22 years among specialists and 4.5 years among residents. A high percentage of specialists have experienced CBDI (46% vs. 17% of residents, p = 0.014). More specialists are familiar with the SCP than residents (49.3% vs. 21.7%, p = 0.021). Significant differences in the mean usefulness score were observed for three rules: rules 2 and 6 were found more useful by residents (mean score: 7.07 vs. 6.01, p = 0.025 and 8.70 vs. 8.27, p < 0.001), and rule 3 was found more useful by specialists (mean: 8.73 vs. 8.36, p < 0.001).

Conclusions

The awareness of the SCP in Europe is low. Participants consider the rules of the SCP to be useful during surgery, although there are differences in the usefulness scores between the groups. An educational program to promote and further implement the SCP should be established.
