Assessment of Gallbladder Drainage Methods in the Treatment of Acute Cholecystitis: A Literature Review.

Gallbladder drainage is a treatment option in high-risk surgical patients with moderate or severe acute cholecystitis. It may be applied as a bridge to cholecystectomy or a definitive treatment option. Apart from the simple and widely accessible percutaneous cholecystostomy, new attractive techniques have emerged in the previous decade, including endoscopic transpapillary gallbladder drainage and endoscopic ultrasound-guided gallbladder drainage. The aim of this paper is to present currently available drainage techniques in the treatment of AC; evaluate their technical and clinical effectiveness, advantages, possible adverse events, and patient outcomes; and illuminate the decision-making path when choosing among various treatment modalities for each patient, depending on their clinical characteristics and the accessibility of methods.

Endoscopic ultrasound-guided gallbladder drainage reduces adverse events compared with percutaneous cholecystostomy in patients who are unfit for cholecystectomy.

Background and study aim There are no data comparing endoscopic ultrasound (EUS)-guided gallbladder drainage (EGBD) with percutaneous cholecystostomy as a treatment for patients with acute cholecystitis. Patients and methods This was a 1 : 1 matched cohort study of all patients who were unfit for cholecystectomy and underwent EGBD or percutaneous cholecystostomy instead for the treatment of acute cholecystitis. The outcomes were matched for age, sex, and American Society of Anesthesiologists grade. Outcome measures included the technical and clinical success rates, adverse events, hospital stay, the number of unplanned admissions, and mortality. Results Between November 2011 and August 2014, a total of 118 patients were included in the study (59 EGBD, 59 percutaneous cholecystostomy). Technical and clinical success rates were similar. In the EGBD group, significantly fewer patients suffered from overall adverse events (19 [32.2 %] vs. 44 [74.6 %]; P < 0.001) and serious adverse events (14 [23.7 %] vs. 44 [74.6 %]; P < 0.001) compared to the percutaneous cholecystostomy group. Patients in the EGBD group required fewer unplanned admissions (4 [6.8 %] vs. 42 [71.2 %]; P < 0.001), which were due to problems related to the cholecystostomy tube in 95.2 %. The 30-day adverse event rates were similar between the groups (17 [28.8 %] vs. 10 [16.9 %]; P = 0.13). For instance, recurrent acute cholecystitis occurred in 0 patients in the EGBD group and in 4 (6.8 %) patients in the percutaneous cholecystostomy group (P = 0.12). The 30-day mortality rates were non-significantly higher in the EGBD group (5 [8.5 %] vs. 1 [1.7 %]; P = 0.21). Conclusions EGBD and percutaneous cholecystostomy were both effective means of achieving gallbladder drainage. EGBD may be a promising alternative to percutaneous cholecystostomy for treatment of acute cholecystitis in patients who are unfit for surgery, provided that experienced endosonographers are available.

Should percutaneous cholecystostomy be used in all cases difficult to manage?

BACKGROUND: Cholecystectomy is the well-accepted management method for acute cholecystitis in patients suitable for surgery. Percutaneous cholecystostomy is planned and used in patients at high surgical risk due to acute symptomatic cholecystitis and/or acute or chronic comorbidity. Percutaneous cholecystostomy can provide permanent treatment, or it may act as a bridge for elective cholecystectomy. METHODS: We presented the outcomes of 50 patients who initially underwent ultrasound-guided transhepatic percutaneous cholecystostomy and 4-6 weeks later, an interval cholecystectomy. All patients had either impaired gallbladder wall integrity on contrast-enhanced abdominal computed tomography performed during admission or had grade II acute cholecystitis according to the Tokyo Guidelines 13 diagnostic criteria and severity grading of acute cholecystitis or exhibited clinical signs of acute cholecystitis on the fifth day of non-operative treatment. RESULTS: Our results suggest that although percutaneous cholecystostomy is a useful method for alleviation of the emergency clinical condition in acute cholecystitis, it makes the interval cholecystectomy more difficult to perform due to the dense fibrosis developing during the healing process, eventually complicating laparoscopic cholecystectomy. CONCLUSION: Cholecystostomy may cause fibrosis during the healing process, eventually complicating laparoscopic cholecystectomy. Thus, there is a need for better evaluation during the identification of indications for cholecystostomy.

Efficacy and Safety of Lumen Apposing Self-Expandable Metal Stents for EUS Guided Cholecystostomy: A Meta-Analysis and Systematic Review.

Background: Patients with acute cholecystitis are treated with early cholecystectomy. A subset of patients are unfit for surgery due to comorbidities and late presentation. Prompt gall bladder drainage (GBD) with percutaneous or endoscopic approach remains a viable therapeutic option for nonoperative candidates. Endoscopic ultrasound (EUS) guided transluminal gall bladder drainage (EUS-GBD) continues to evolve as an alternative approach to percutaneous drainage. With continued refinement in stent technology, lumen apposing self-expandable metal stent (LAMS) offers several advantages. We performed a pooled analysis on the efficacy and safety of EUS-GBD with LAMS in nonoperative candidates with acute cholecystitis. Methods: Extensive English language literature search was performed in Medline, Embase, Cochrane Central, and Google Scholar using keywords "endoscopic ultrasound", "stent", "gallbladder", "acute cholecystitis", and "cholecystostomy" from Jan 2000 to Dec 2016. Fixed and random effects models were used to calculate the pooled proportions. Results: Data was extracted from 13 studies that met the inclusion criteria (n = 233). Pooled proportion of technical success was 93.86% (95% CI = 90.56 to 96.49) and clinical success was 92.48% (95% CI = 88.9 to 95.42). Overall complication rate was 18.31% (95% CI = 13.49 to 23.68) and stent related complication rate was 8.16% (95% CI = 4.03 to 14.96) in the pooled percentage of patients. Pooled proportion for perforation was 6.71% (95% CI 3.65 to 10.6) and recurrent cholangitis/cholecystitis was noted in 4.05% (95% CI = 1.64 to 7.48). Publication bias calculated using Harbord-Egger bias indicator gave a value of -0.61 (95% CI = -1.39 to 0.16, p = 0.11). The Begg-Mazumdar indicator for bias gave Kendall's tau b value of -0.42 (p ≥ 0.05). Conclusions: EUS-GBD with LAMS is a safe and alternative treatment modality for patients needing gallbladder drainage, with acceptable intraprocedural and postprocedural complications. However, due to the limited data and lack of direct comparison with other methods, further controlled trials are necessary to estimate the overall efficacy and safety and the role of EUS-GBD with LAMS in management of nonoperative patients with acute cholecystitis.

Thoracic Empyema Caused by Percutaneous Transhepatic Gallbladder Drainage.

Percutaneous transhepatic gallbladder drainage (PTGBD) is an alternative to emergency laparoscopic cholecystectomy in high-risk patients with acute cholecystitis. Severe complications of this procedure are rare, except for drainage tube-related complications. A case of thoracic empyema, which is a rare complication of PTGBD, is reported; penetration of the pleural cavity seemed to be the cause of the thoracic empyema.
