Subtotal Fenestrating Cholecystectomy: A Safe and Effective Approach to the Difficult Gallbladder

Laparoscopic subtotal cholecystectomy outcomes across a low-and middle-income country metropolitan health service

BACKGROUND

Laparoscopic subtotal cholecystectomy (LSC) is a safe alternative for difficult cholecystectomies to prevent bile duct injury and open conversion. The primary aim was to detail the use and outcomes on LSCs.

METHODS

Retrospective analysis of a prospectively maintained database of laparoscopic cholecystectomy (LC). Relative clinical factors, outcomes, and 30-day follow-up between LSC and LC were compared using univariate and multivariate analyses.

RESULTS

Six hundred and twenty four cholecystectomies were performed and 53 (8.5%) required LSC. 81.8% were fenestrating LSC. Male sex was significantly overrepresented in the LSC group (p < 0.01) and patients requiring LSC were significantly older (p < 0.01). Same admission cholecystectomy was associated with a higher risk of LSC (p < 0.01). Patients with a history of previous surgery, preoperative ERCP, or percutaneous cholecystostomy had an increased risk of undergoing LSC (p < 0.01). A necrotic gallbladder was the most significant predictor of the need for a LSC (p < 0.001). A contracted gallbladder, extensive adhesions, gallbladder empyema, and severe inflammation were significant predictors of difficulty (all p < 0.01). Postoperative complications occurred in 26.4% of LSC patients. There were ten (18.9%) Clavien-Dindo Grade III complications, 5.7% required ERCPs, and 9.4% required relook laparotomies. Significantly, more patients in the LSC group developed bile leaks (n = 8, 15%) (p < 0.001). There were two readmissions within 30 days, one mortality, and no BDIs occurred in the LSC cohort.

CONCLUSION

LSC provides a feasible surgical option that should be utilized in complex cholecystitis.

How do magnetic resonance cholangiopancreatography findings predict conversion from laparoscopic cholecystectomy for acute cholecystitis to bailout procedures?

BACKGROUND

Acute cholecystitis is one of the most prevalent surgical abdominal conditions. The Tokyo Guidelines describe the management of acute cholecystitis and recommend bailout procedures for "difficult" cholecystitis cases. This study aimed to identify risk factors for conversion from laparoscopic cholecystectomy to bailout procedures in patients with acute cholecystitis.

METHODS

This retrospective cohort study was conducted at a single center between January 2017 and December 2021. Patients who underwent laparoscopic cholecystectomy for acute cholecystitis were enrolled and classified into bailout and non-bailout groups. The patients' characteristics and perioperative data were compared between the 2 groups.

RESULTS

In total, 161 patients who underwent laparoscopic cholecystectomy for acute cholecystitis were reviewed. Fourteen were excluded because of a lack of preoperative magnetic resonance cholangiopancreatography; thus, 147 patients were enrolled (bailout group, 21; non-bailout group, 126). Age (74 vs 67 years old; P = .048), days from onset to surgery (3 vs 2 days; P = .02), or defect of cystic duct in magnetic resonance cholangiopancreatography (57% vs 29%; P = .02) were significantly associated with conversion to bailout procedures. In the logistic regression analysis, a defect of the cystic duct in magnetic resonance cholangiopancreatography was an independent predictor for bailout procedures (odds ratio, 2.793; P = .04).

CONCLUSION

In this study, defect of the cystic duct in the magnetic resonance cholangiopancreatography can predict conversion to bailout procedures. To the best of our knowledge, this is the first report to describe magnetic resonance cholangiopancreatography finding of the cystic duct as a predictor of surgical difficulty in patients with acute cholecystitis.

Review of the Literature on Partial Resections of the Gallbladder, 1898-2022: The Outline of the Conception of Subtotal Cholecystectomy and a Suggestion to Use the Terms 'Subtotal Open-Tract Cholecystectomy' and 'Subtotal Closed-Tract Cholecystectomy'

Current descriptions of the history of subtotal cholecystectomy require more details and accuracy. This study presented a narrative review of the articles on partial resections of the gallbladder published between 1898 and 2022. The Scale for the Assessment of Narrative Review Articles items guided the style and content of this paper. The systematic literature search yielded 165 publications. Of them, 27 were published between 1898 and 1984. The evolution of the partial resections of the gallbladder began in the last decade of the 19th century when Kehr and Mayo performed them. The technique of partial resection of the gallbladder leaving the hepatic wall in situ was well known in the 3rd and 4th decades of the 20th century. In 1931, Estes emphasised the term 'partial cholecystectomy'. In 1947, Morse and Barb introduced the term 'subtotal cholecystectomy'. Madding and Farrow popularised it in 1955-1959. Bornman and Terblanche revitalised it in 1985. This term became dominant in 2014. From a subtotal cholecystectomy technical execution perspective, it is either a single-stage (when it includes only the resectional component) or two-stage (when it also entails closure of the remnant of the gallbladder or cystic duct) operation. Recent papers on classifications of partial resections of the gallbladder indicate the extent of gallbladder resection. Subtotal cholecystectomy is an umbrella term for incomplete cholecystectomies. 'Subtotal open-tract cholecystectomy' and 'subtotal closed-tract cholecystectomy' are terms that characterise the type of completion of subtotal cholecystectomy.

State of the art in subtotal cholecystectomy: An overview

Introduction

Subtotal cholecystectomy is a type of surgical bail-out procedure indicated when facing difficult laparoscopic cholecystectomy due to not reaching the critical view of safety, inadequate identification of the anatomical structures involved and/or risk of injury.

Materials and methods

A comprehensive search on PubMed were performed using the following Mesh terms: Subtotal cholecystectomy and Partial cholecystectomy. The PubMed databases were used to search for English-language reports related to Subtotal cholecystectomy between January 1, 1987, the date of the first published laparoscopic cholecystectomy, through January 2023. 41 studies were included.

Results

Subtotal cholecystectomy's incidence oscillates between 4.00% and 9.38%. Strasberg et al., divided subtotal cholecystectomies in "fenestrating" and "reconstituting" types based on if the remaining portion of the gallbladder was left open or closed. Subtotal cholecystectomy can sometimes be a challenging procedure and is associated to a high rate of complications such as biliary fistula, retained gallstones, subhepatic or subphrenic collections, among others.

Conslusion

Subtotal cholecystectomy is a safe alternative when facing difficult cholecystectomy in which the critical view of safety is not reached in order to avoid complications. A classification system should be implemented in surgical descriptions to compare the different surgical techniques employed. In order to avoid bile leakage and cholecystitis of the remnant gallbladder, the surgical technique must be performed skillfully. There is still a current lack of information on alternative techniques such as omental plugging or falciform patch in order to judge their utility. There needs to be further research on long-term complications such as malignancy of the remnant gallbladder.
