Randomized clinical trial of intraoperative endoscopic retrograde cholangiopancreatography versus laparoscopic bile duct exploration in patients with choledocholithiasis

Surgical Versus Conservative Management of Delayed Presentation of Acute Biliary Disease: A Systematic Literature Review

Biliary sepsis, characterized by contamination and infection of the biliary tract, poses a serious medical issue with detrimental effects on the patients. While cholecystectomy is the usual treatment for symptomatic gallstones, the most desirable management approach for biliary sepsis remains debated, prompting a scientific evaluation of the long-term effects of cholecystectomy. To compare the long-term outcomes of biliary sepsis in patients undergoing cholecystectomy versus conservative management (CM), this study will systematically review the existing literature to clarify differences in recurrence rates, complication rates, and overall survival. PubMed and the Cochrane Library were searched thoroughly for the literature review. Studies were included if they reported the effects of surgical and conservative interventions on predefined patient outcomes. A critical appraisal of the studies included was performed using CASP criteria. Fourteen studies were included, comprising prospective cohort studies and randomized controlled trials, with sample sizes varying from 52 to 234 patients. Endoscopic sphincterotomy (ES), early versus delayed laparoscopic cholecystectomy (D-LC), combined endoscopic-laparoscopic techniques, and percutaneous cholecystostomy followed by early laparoscopic cholecystectomy (E-LC) were the analyzed interventions. The primary conclusions showed that, in comparison to D-LC, E-LC significantly reduced hospital stays (p < 0.05), since the times were 58 and 167 hours for E-LC and D-LC, respectively. Additionally, E-LC resulted in fewer recurrent biliary events (4.3 compared to 36.2% of D-LC) and lower overall costs. ES demonstrated efficacy in mitigating the requirement for emergency cholecystectomy in patients at high risk, as evidenced by its 94% success rate in endoscopic stone removal. Without increasing postoperative complications, combined endoscopic-laparoscopic techniques showed high success rates for stone removal (95.6% common bile duct clearance rate). This systematic review highlights the favorable long-term effects of cholecystectomy in managing biliary sepsis. It emphasizes the importance of individualized treatment processes and considers conservative control for patients with high surgical risk and significant comorbidities. It also highlights the need for advancement in CM and provides insights that can help clinical decision-making to optimize outcomes in affected patients.

Pragmatic algorithm for management of common bile duct calculi in resource-limited settings in India

INTRODUCTION

Endoscopic retrograde cholangiopancreatography (ERCP) facilitates the removal of common bile duct (CBD) calculi by endoscopy. When ERCP fails, exploration of CBD is required for the clearance of CBD calculi. The optimum way for the exploration of CBD is by choledochoscopy. Dedicated flexible or rigid choledochoscopes are expensive and available only in few places in India. Since 1991, we subjected patients with suspected CBD calculi to ERCP, followed by laparoscopic cholecystectomy (LC). Patients in whom ERCP failed to clear CBD were subjected to open exploration of CBD using any easily available, suitable, straight rigid scope for choledochoscopy.

PATIENTS AND METHODS

Since March 1991, out of 8866 patients with cholelithiasis, 862 underwent ERCP. Ninety-six patients in whom ERCP failed to clear CBD underwent open exploration of CBD. In each case of exploration of CBD, choledochoscopy was performed using a straight rigid scope, either a cystoscope, paediatric cystoscope, hysteroscope or 5-mm laparoscopy telescope with a 5-mm cannula.

RESULTS

The CBD clearance was complete in 95 patients, and one patient had an impacted calculus at the ampulla. CBD explorations were followed by choledochoduodenostomy, T-tube placement or suturing of choledochotomy. No residual calculi were observed after such exploration.

CONCLUSION

From our results, we advocate the following algorithm for CBD calculi in resource-limited settings. Subject patients with CBD calculi to ERCP followed by LC. In case of failed ERCP, open exploration of CBD with choledochoscopy using any suitable rigid scope. Dedicated flexible or rigid choledochoscope is not essential. This approach is cost-effective and successful.

Systematic Appraisal of Guidelines for the Diagnosis and Treatment of Choledocholithiasis

BACKGROUND

To systematically evaluate the methodological quality of the current up-to-date guidelines pertaining to choledocholithiasis, we conducted a comprehensive analysis of key recommendations and corresponding evidence, focusing on the heterogeneity among these guidelines.

METHOD

Systematic searches across various databases were performed to identify the latest guidelines. The identified guidelines, which met the inclusion criteria, underwent evaluation using the Appraisal of Guidelines for Research and Evaluation II (AGREE II) tool. The key recommendations and evidence from the included guidelines were extracted and reclassified using the Oxford Centre for Evidence-Based Medicine (OCEBM) grading system, and the obtained results were analyzed.

RESULTS

Nine guidelines related to choledocholithiasis were included in this study, out of which 4 achieved an overall standardized score of more than 60%, indicating their suitability for recommendation. Upon closer examination of the main recommendations within these guidelines, we discovered significant discrepancies concerning the utilization of similar treatment techniques for different diseases or different treatment methods under comparable conditions, and discrepancies in the recommended treatment duration. High-quality research evidence was lacking, and some recommendations either failed to provide supporting evidence or cited inappropriate and low-level evidence.

CONCLUSION

The quality of guidelines pertaining to choledocholithiasis is uneven. Recommendations for the treatment of choledocholithiasis demonstrate considerable disparities among the guidelines, particularly regarding the utilization of endoscopic retrograde cholangiopancreatography as a treatment method and the management approaches for difficult stone cases. Improvements by guideline developers for these factors contributing to the heterogeneity would be a reasonable approach to further update the guidelines for cholangiolithiasis.

Minimally invasive management of concomitant gallstones and common bile duct stones: an updated network meta-analysis of randomized controlled trials

BACKGROUND

To update a 2018 meta-analysis on the comparative efficacy and safety of four surgical techniques in patients with concomitant gallstones and common bile duct (CBD) stones.

METHODS

Randomized controlled trials (RCTs) comparing laparoscopic cholecystectomy (LC) plus laparoscopic common bile duct exploration (LCBDE), LC plus preoperative endoscopic retrograde cholangiopancreatography (PreERCP), LC plus intraoperative ERCP (IntraERCP), and LC plus postoperative ERCP (PostERCP) were included. Primary and secondary outcomes were compared using odds ratio, weighted mean difference, and 95% confidence intervals.

RESULTS

Twenty-five RCTs involved 3145 patients were included. Of these, 1188 (37.8%) underwent LC + PreERCP, 1183 (37.6%) LC + LCBDE, 689 (21.9%) LC + IntraERCP, and 85 (2.7%) LC + PostERCP. This analysis demonstrated that LC plus IntraERCP was the most likely approach to achieve technical success and reduce morbidity. No significant differences were observed between the four treatments concerning major morbidity, mortality, and operative time. LC plus LCBDE was effective for increasing biliary leak and conversion as well as decreasing postoperative hemorrhage and total costs. Additionally, LC plus PreERCP was associated with higher postoperative pancreatitis, while LC plus IntraERCP was associated with a shorter length of hospital stay. There was significant heterogeneity in operative time, hospital stay, and total costs (τ2 > 1).

CONCLUSIONS

This analysis provides evidence that LC plus IntraERCP appears to be the optimal strategy for patients with concomitant gallstones and CBD stones owing to its advantage in technical success and morbidity. LC plus LCBDE is associated with higher biliary leak and lower postoperative hemorrhage, whereas LC plus PreERCP is associated with higher postoperative pancreatitis.

Outcomes following common bile duct exploration versus endoscopic stone extraction before, during and after laparoscopic cholecystectomy for patients with common bile duct stones

BACKGROUND

Laparoscopic common bile duct exploration (LCBDE) and endoscopic retrograde cholangiopancreatography (ERCP) are two methods of retrieving common bile duct (CBD) stones. The best method for CBD stone removal is debatable. The aim of this study was to compare outcomes following LCBDE and/or ERCP, including laparoscopic cholecystectomy.

METHODS

Data were collected retrospectively for patients undergoing LCBDE and/or ERCP at a single centre from 2008 to 2018. Patients were grouped by intention-to-treat (single-stage LCBDE, pre-operative-, intra-operative-, or post-operative ERCP) and eventual plan (surgical or endoscopic). Outcomes included complication rates (minor Clavien-Dindo 1/2, major Clavien-Dindo 3/4, non-biliary complications) and mortality.

RESULTS

Of 671 patients, 578 patients received LCBDE and 93 patients received ERCP as primary care. Endoscopic clearance had significantly higher complications and mortality compared to surgical clearance. On an intention-to-treat basis LCBDE had the lowest minor-, major- and non-biliary complications, and mortality (5.2%, 6.1%, 2.9% and 0.5%, respectively), whilst pre-operative ERCP the worst (39.6%, 27.1%, 29.2% and 8.3%, respectively) (p=<0.001). LCBDE and postERCP had similar major complications and mortality.

CONCLUSION

Surgical clearance of CBD stones was potentially safer than endoscopic clearance. Pre-operative ERCP had the worst outcomes. LCBDE and postERCP are likely to have similar short-term patient outcomes.

Common bile duct stones management: A network meta-analysis

BACKGROUND

Timely management is critical for treating symptomatic common bile duct (CBD) stones; however, a single optimal management strategy has yet to be defined in the acute care setting. Consequently, this systematic review and network meta-analysis, comparing one-stage (CBD exploration or intraoperative endoscopic retrograde cholangiopancreatography [ERCP] with simultaneous cholecystectomy) and two-stage (precholecystectomy or postcholecystectomy ERCP) procedures, was undertaken with the main outcomes of interest being postprocedural complications and hospital length of stay (LOS).

METHODS

PubMed, SCOPUS, MEDLINE, Embase, and Cochrane Central Register of Controlled Trials were methodically queried for articles from 2010 to 2021. The search terms were a combination of medical subject headings terms and the subsequent terms: gallstone; common bile duct (stone); choledocholithiasis; cholecystitis; endoscopic retrograde cholangiography/ERCP; common bile duct exploration; intraoperative, preoperative, perioperative, and postoperative endoscopic retrograde cholangiography; stone extraction; and one-stage and two-stage procedure. Studies that compared two procedures or more were included, whereas studies not recording complications (bile leak, hemorrhage, pancreatitis, perforation, intra-abdominal infections, and other infections) or LOS were excluded. A network meta-analysis was conducted to compare the four different approaches for managing CBD stones.

RESULTS

A total of 16 studies (8,644 participants) addressing the LOS and 41 studies (19,756 participants) addressing postprocedural complications were included in the analysis. The one-stage approaches were associated with a decrease in LOS compared with the two-stage approaches. Common bile duct exploration demonstrated a lower overall risk of complications compared with preoperative ERCP, but there were no differences in the overall risk of complications in the remaining comparisons. However, differences in specific postprocedural complications were detected between the four different approaches managing CBD stones.

CONCLUSION

This network meta-analysis suggests that both laparoscopic CBD exploration and intraoperative ERCP have equally good outcomes and provide a preferable single-anesthesia patient pathway with a shorter overall length of hospital stay compared with the two-stage approaches.

EAES rapid guideline: updated systematic review, network meta-analysis, CINeMA and GRADE assessment, and evidence-informed European recommendations on the management of common bile duct stones

BACKGROUND

Choledocholithiasis presents in a considerable proportion of patients with gallbladder disease. There are several management options, including preoperative or intraoperative endoscopic cholangiopancreatography (ERCP), and laparoscopic common bile duct exploration (LCBDE).

OBJECTIVE

To develop evidence-informed, interdisciplinary, European recommendations on the management of common bile duct stones in the context of intact gallbladder with a clinical decision to intervene to both the gallbladder and the common bile duct stones.

METHODS

We updated a systematic review and network meta-analysis of LCBDE, preoperative, intraoperative, and postoperative ERCP. We formed evidence summaries using the GRADE and the CINeMA methodology, and a panel of general surgeons, gastroenterologists, and a patient representative contributed to the development of a GRADE evidence-to-decision framework to select among multiple interventions.

RESULTS

The panel reached unanimous consensus on the first Delphi round. We suggest LCBDE over preoperative, intraoperative, or postoperative ERCP, when surgical experience and expertise are available; intraoperative ERCP over LCBDE, preoperative or postoperative ERCP, when this is logistically feasible in a given healthcare setting; and preoperative ERCP over LCBDE or postoperative ERCP, when intraoperative ERCP is not feasible and there is insufficient experience or expertise with LCBDE (weak recommendation). The evidence summaries and decision aids are available on the platform MAGICapp ( https://app.magicapp.org/#/guideline/nJ5zyL ).

CONCLUSION

We developed a rapid guideline on the management of common bile duct stones in line with latest methodological standards. It can be used by healthcare professionals and other stakeholders to inform clinical and policy decisions.

Comparing One-Stage vs Two-Stage Approaches for the Management of Choledocholithiasis

BACKGROUND

The management of symptomatic choledocholithiasis remains a controversial issue. At present, the three most common management options for choledocholithiasis include a preoperative endoscopic retrograde cholangiopancreatography with sphincterotomy and stone extraction followed by laparoscopic cholecystectomy, then by either an intraoperative endoscopic retrograde cholangiopancreatography with sphincterotomy or a laparoscopic common bile duct exploration. The purpose of this study was to assess the consequences of the decision to pursue each of these three methods.

METHODS

We conducted a review of the existing data comparing these three management options. The literature from 2009 to 2021 pertaining to these three methods was reviewed for data on duct clearance, morbidity, mortality, recurrence rate, length of stay, and operative time. Next, we constructed decision trees for each method using a utility score analysis, and these utility scores were used to create a sensitivity analysis based on stone clearance rate.

RESULTS

Laparoscopic cholecystectomy with intraoperative endoscopic retrograde cholangiopancreatography had a utility score of 0.9910, a stone clearance rate of 95.5%, a morbidity of 6.3%, and a mortality of 0.2%. Preoperative endoscopic retrograde cholangiopancreatography with laparoscopic cholecystectomy had a utility score of 0.9629, a stone clearance rate of 85.5%, a morbidity of 13.3%, and a mortality of 0.8%. Laparoscopic cholecystectomy with common bile duct exploration had a utility score of 0.9882, a stone clearance rate of 88.3%, a morbidity of 12.9%, and a mortality of 0.3%.

CONCLUSION

We have shown that a laparoscopic cholecystectomy with an intraoperative endoscopic retrograde cholangiopancreatography is associated with the best overall outcomes.

Long-term mortality and intestinal obstruction after laparoscopic cholecystectomy: A systematic review and meta-analysis

BACKGROUND

Long-term outcomes of cholecystectomy are largely unknown though it is a common procedure in general surgery. We aimed to investigate the long-term mortality rate and incidence of intestinal obstruction after laparoscopic cholecystectomy.

MATERIALS AND METHODS

This systematic review and meta-analysis was reported according to the PRISMA 2020 and AMSTAR guidelines. A protocol was registered on PROSPERO (CRD42020178906). The databases PubMed, EMBASE, and Cochrane CENTRAL were last searched on February 9, 2022 for original studies on long-term complications with n > 40 and follow-up ≥ 6 months. Outcomes were long-term mortality and incidence of intestinal obstruction, and meta-analyses were conducted. Risk of bias was assessed with Newcastle-Ottawa Scale and Cochrane "Risk of bias"-tool according to study design.

RESULTS

We included 41 studies that reported long-term follow-up on 1,000,534 patients. Of these, 38 studies reported on mortality (514,242 patients) that ranged from 0 to 32%. Meta-analysis estimated a long-term mortality rate of 2.0% (95% CI 1.7-2.3%) after laparoscopic cholecystectomy. Five studies including 486,292 patients reported on intestinal obstruction that ranged from 0 to 6%. Meta-analysis estimated a long-term rate of intestinal obstruction of 1.3% (95% CI 0.8-1.8%).

CONCLUSION

Long-term mortality after laparoscopic cholecystectomy was 2%. The incidence of long-term intestinal obstruction after laparoscopic cholecystectomy was 1.3%.

Destiny for Rendezvous: Is Cholecysto/Choledocholithiasis Better Treated with Dual- or Single-Step Procedures?

Biliary lithiasis is common worldwide, affecting almost 20% of the general population, though few experience symptoms. The frequency of choledocholithiasis in patients with symptomatic cholelithiasis is estimated to be 10-33%, depending on patients' age. Unlike gallbladder lithiasis, the medical and surgical treatment of common bile duct stones is uncertain, having changed over the last few years. The prior gold standard treatment for cholelithiasis and choledocholithiasis was open cholecystectomy with bile duct clearance, choledochotomy, and/or surgical sphincterotomy. In the last 10-15 years, new treatment approaches to the complex pathology of choledocholithiasis have emerged with the advent of endoscopic retrograde cholangiopancreatography (ERCP), laparoscopic surgery, and advanced diagnostic procedures. Although ERCP followed by laparoscopic cholecystectomy is the preferred mode of management, a single-step strategy (laparo-endoscopic rendezvous) has gained acceptance due to lesser morbidity and a lower risk of iatrogenic damage. Given the above, a tailored approach relying on careful evaluation of the disease is necessary in order to minimize complication risks and overall costs. Yet, the debate remains open, with no consensus on the superiority of laparo-endoscopic rendezvous to more conventional approaches.

Endoscopic Stone Extraction followed by Laparoscopic Cholecystectomy in Tandem for Concomitant Cholelithiasis and Choledocholithiasis: A Prospective Study

BACKGROUND

Single-session endoscopic stone extraction (ESE) and laparoscopic cholecystectomy (LC) has the best outcome in managing concomitant cholelithiasis (gallstone disease [GSD]) and choledocholithiasis (common bile duct stone [CBDS]). Traditional rendezvous technique with an intraoperative cholangiogram is associated with various technical (bowel distention, frozen Calot's triangle, limitation of intraoperative cholangiogram and so on) and logistical difficulties (lack of trained personnel and equipment for ESE in the operating room). We modified our approach of ESE-LC (tandem ESE-LC) to study the safety of the approach and overcome these disadvantages of the traditional rendezvous approach.

METHODS

A prospective study of patients with GSD and suspected CBDS from January 2017 to December 2019 was conducted. Tandem ESE-LC involves ESE and LC under the same general anaesthesia in a single day, while ESE is performed in the endoscopic suite using carbon dioxide insufflation, a balloon/basket was used for achieving bile duct clearance and the same was confirmed with an occlusion cholangiogram. Patients were then shifted to the operating room for LC. The primary outcome included bile duct clearance and safety of the procedure.

RESULTS

Of 56 patients assessed for eligibility, 42 were included in the study (median age: 53 years, 25 [60%] women). Biliary colic was the most common presenting symptom (n = 24, 57%), followed by acute cholecystitis (n = 11, 26%). The median number of stones and stone size was 1 (1-6) and 4 mm (3-10), respectively. All patients had successful bile duct clearance. Stenting was performed in 5 (12%) patients. Intraoperatively, Calot's dissection was difficult and frozen in 10 and 11 patients respectively. The cystic duct was short and wide in 13 (31%) patients. Subtotal cholecystectomy was performed in 6 (14%) patients. The median duration of postprocedural hospital stay was 1 (0-13) day. Three patients had tandem ESE-LC on a day-care basis. One patient had post-endoscopic retrograde cholangiopancretography pancreatitis, and another required percutaneous drainage for gall bladder fossa collection. No patient had retained CBDS at a median follow-up of 18 (3-28) months.

CONCLUSION

Tandem ESE-LC is safe and effective method in managing concomitant GSD and CBDS.

Impact of single-stage laparoscopic trans-cystic exploration on hospital procedures, admissions and length-of-stay in common bile duct stone clearance

BACKGROUND

Single-stage approach with bile duct exploration is considered the most efficient and cost-effective method of bile duct clearance. In Australia, apart from centres with subspecialty interests, notably in Brisbane, Queensland, a multi-stage approach with endoscopic retrograde cholangiopancreatography (ERCP) is used more frequently. We aim to evaluate the impact of single stage laparoscopic trans-cystic exploration (LTCE) versus multi-stage approach for choledocholithiasis.

METHODS

This was a retrospective cohort study. Medicare Benefits Schedule codings were used to identify patients who had the following procedures between December 2011 and December 2019: laparoscopic cholecystectomy (LC) and ERCP, LC and LTCE, LC and LTCE and ERCP. Primary outcomes were number of hospital procedures, admissions and additive length of stay (aLOS), the cumulative hospital stay from admission to discharge.

RESULTS

Of 607 patients, 204 (34%) patients received a single-stage LTCE, while 403 (66%) patients had a multi-stage approach. In the LTCE group, 82% (168) patients and 93% (190) patients had one procedure and one admission respectively for stone clearance (P = 0.001). The median aLOS was 4 days for LTCE versus 7 days for multi-stage approach (P = 0.001; 95% CI for difference - 3 to -2). In the multi-stage group, 16% (65) patients had three or more procedures and 49% (199) patients required two or more hospital admissions to achieve stone clearance.

CONCLUSION

LTCE for stone clearance can be successfully accomplished with reductions in hospital admissions, number of procedures and length of stay. This has further economic and health resource implications.

Contemporary management of concomitant gallstones and common bile duct stones: a survey of Spanish surgeons

BACKGROUND

Concomitant gallstones and common bile duct stones (CBDS) is a relatively frequent presentation. The optimal treatment remains controversial and the debate persists between two strategies. The one-stage approach: laparoscopic cholecystectomy with laparoscopic common bile duct exploration (LCBDE) has been shown to be equally safe and more cost-effective than the more traditional two-stage approach: endoscopic retrograde cholangiography followed by laparoscopic cholecystectomy (ERCP + LC). However, many surgeons worldwide still prefer the two-stage procedure. This survey evaluated contemporary management of CBDS in Spain and assessed the impact of surgeon and hospital factors on provision of LCBDE.

METHODS

A 25-item, web-based anonymous survey was sent to general surgeons members of the Spanish Surgeons Association. Descriptive statistics were applied to summarize results.

RESULTS

Responses from 305 surgeons across 173 Spanish hospitals were analyzed. ERCP is the initial approach for preoperatively suspected CBDS for 86% of surgeons. LCBDE is the preferred method for only 11% of surgeons and only 11% treat more than 10 cases per year. For CBDS discovered intraoperatively, 59% of respondents attempt extraction while 32% defer to a postoperative ERCP. The main reasons cited for not performing LCBDE were lack of equipment, training and timely availability of an ERCP proceduralist. Despite these barriers, most surgeons (84%) responded that LCBDE should be implemented in their departments.

CONCLUSIONS

ERCP was the preferred approach for CBDS for the majority of respondents. There remains limited use of LCBDE despite many surgeons indicating it should be implemented. Focused planning and resourcing of both training and operational demands are required to facilitate adoption of LCBDE as option for patients.

Comparison of intraoperative endoscopic retrograde cholangiopancreatography and laparoscopic common bile duct exploration combined with laparoscopic cholecystectomy for treating gallstones and common bile duct stones: a systematic review and meta-analysis

BACKGROUND

This study aimed to compare the efficacy and safety of laparoscopic cholecystectomy combined with intraoperative endoscopic retrograde cholangiopancreatography (LC-IntraERCP) and laparoscopic cholecystectomy combined with laparoscopic common bile duct exploration (LC-LCBDE) to determine which one-stage therapeutic strategy provides better outcomes for patients with gallstones and common bile duct stones.

METHODS

Cochrane Library, EMBASE, PubMed, and Web of Science databases were searched to identify eligible articles from the database inception to September 2020. The revised Cochrane risk of bias tools for randomized trials (RoB-2) and non-randomized interventions (ROBINS-I) was used to assess the quality of the included studies. The overall quality of evidence was assessed through the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) tool. The primary outcomes consisted of surgical success, retained stones, and overall postoperative complications, while secondary outcomes included postoperative bleeding, postoperative pancreatitis, postoperative bile leakage, conversion to laparotomy, and operative time.

RESULTS

Eight studies (four RCTs and four Non-RCTs with high quality) with 2948 patients were included. No significant difference was seen between the two groups regarding surgical success, overall postoperative complications, conversion to laparotomy, and operative time. The meta-analysis demonstrated that in the LC-IntraERCP group, the rate of retained stones (OR 0.51, 95% CI 0.28-0.91) and postoperative bile leakage were lower (OR 0.25, 95% CI 0.09-0.69), while in the LC-LCBDE group, postoperative bleeding (OR 5.24, 95% CI 1.65-16.65) and postoperative pancreatitis (OR 4.80, 95% CI 2.35-9.78) decreased.

CONCLUSIONS

LC-IntraERCP and LC-LCBDE exhibited similar efficacies when surgical success rate, overall postoperative complications, conversion to laparotomy, and operative time were compared. However, LC-IntraERCP is probably to be more effective in terms of lowering the rate of retained stones.

One-stage versus two-stage management for acute cholecystitis associated with common bile duct stones: a retrospective cohort study

BACKGROUND

Both one-stage [laparoscopic cholecystectomy (LC) plus laparoscopic common bile duct exploration (LCBDE)] and two-stage [endoscopic retrograde cholangiopancreatography (ERCP) followed by sequential LC] approaches are effective treatment for concomitant common bile duct (CBD) stones and gallstone. Although many studies compared one-stage with two-stage surgical approach for cholecysto-choledocholithiasis, there are very few studies compared the two management strategies for acute cholecystitis (AC) associated with CBD stones.

METHODS

Between January 2014 and December 2019, patients with concomitant AC and CBD stones proposed to early surgery were retrospectively studied. The patients were scheduled to undergo either the one-stage [LCBDE and LC (LCBDE+LC) were undertaken at the same operation] or two-stage [preoperative ERCP for CBD stone clearance was followed by LC 1-3 days later (pre-ERCP+LC)] procedure. The success rate of complete stone clearance, procedure-related complication, hospital stay, hospitalization charges and later biliary complications were compared between the two groups.

RESULTS

Sixty patients were included in the study, 28 in the one-stage group and 32 in the two-stage group. There was no significant difference in the success rate of complete stone clearance (96.4% vs. 93.8%, P = 1.000), complication rate (10.7% vs. 9.4%, P = 1.000), incidence of pancreatitis (0 vs. 6.3%, P = 0.494) or length of hospital stay (12 ± 5 vs. 11 ± 4 days, P = 0.393) between the two groups.

CONCLUSION

For patients with concomitant AC and choledocholithiasis proposed to early surgery, both the one-stage (LCBDE+LC) and two-stage (pre-ERCP+LC) approaches were acceptable and broadly comparable in achieving clearance of CBD stones.

Laparoscopic common bile duct exploration versus intraoperative endoscopic retrograde cholangiopancreatography in patients with gallbladder and common bile duct stones: a meta-analysis

BACKGROUND

To compare the efficacy and safety of laparoscopic common bile duct exploration plus laparoscopic cholecystectomy (LCBDE + LC) with intraoperative endoscopic retrograde cholangiopancreatography plus laparoscopic cholecystectomy (IO-ERCP + LC) for the treatment of gallbladder and common bile duct (CBD) stones.

METHODS

We searched PubMed, Ovid, and Cochrane Library from their inception dates to April 2020, for studies that compared the efficacy and safety of LCBDE + LC with those of IO-ERCP + LC in patients with gallbladder and CBD stones. The technical success, morbidity, major morbidity, biliary leak, postoperative pancreatitis, conversion, retained stones, operative time, and postoperative hospital stay were compared between these two approaches.

RESULTS

Five randomized controlled trials involving 860 patients were evaluated. Overall, no significant difference was found between LCBDE + LC and IO-ERCP + LC regarding technical success, morbidity, major morbidity, and the conversion rate. Biliary leak and retained stones were significantly more prevalent in the LCBDE + LC group, while postoperative pancreatitis was significantly more prevalent in the IO-ERCP + LC group.

CONCLUSIONS

LCBDE + LC and IO-ERCP + LC have similar efficacy and safety in terms of technical success, morbidity, major morbidity, and conversion rate. However, LCBDE + LC is associated with a higher biliary leak rate, lower postoperative pancreatitis rate, and higher rate of retained stones.

Single-stage management of choledocholithiasis: intraoperative ERCP versus laparoscopic common bile duct exploration

BACKGROUND

Laparoscopic cholecystectomy (LC) is the criterion standard for treating patients with symptomatic gallstone disease; however, the optimal technique for extracting common bile duct stones remains unclear. Recent studies have noted improved outcomes with single-stage techniques, such as intraoperative endoscopic retrograde cholangiopancreatography (iERCP) and laparoscopic common bile duct exploration (LCBDE); however only few studies have directly compared those two single-stage techniques.

OBJECTIVES

Using the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database, we retrospectively analyzed the postoperative outcomes of all patients who underwent single-stage LC for choledocholithiasis from 2005 to 2017. Using Current Procedural Terminology (CPT) codes, as well as International Classification of Diseases, Ninth Revision (ICD-9) and 10th Revision (ICD-10) codes, we stratified patients into two cohorts: those who underwent iERCP and LCBDE. Applying univariate techniques, we evaluated baseline characteristics and postoperative outcomes for both cohorts. Our primary outcomes of interest were 30-day morbidity and 30-day mortality; our secondary outcomes included rates of reoperation, readmission, operative time, and hospital length of stay.

RESULTS

Of the 1814 single-stage LC patients during our 13-year study period, 1185 (65.3%) underwent LCBDE; 629 (34.6%) underwent iERCP. Our univariate analysis showed that the two cohorts were homogeneous in terms of baseline characteristics, including demographics, preoperative comorbidities, laboratory values, and American Society of Anesthesiologists (ASA) scores. 30-day postoperative morbidity (including infectious and noninfectious complications) and overall mortality between groups were low and comparable. The mean operative time was slightly longer with LCBDE (125.1 ± 62.0 min) than iERCP (113.5 ± 65.2 min; P < 0.001), however the mean hospital length of stay, readmission rate, and reoperation rate were similar.

CONCLUSION

We found that both iERCP and LCBDE resulted in low, comparable rates of morbidity and mortality. Centers with readily available endoscopic expertise might favor iERCP for its ease of access and shorter operative time. However, LCBDE remains an appropriate technique for patients with choledocholithiasis, especially when immediate endoscopic intervention is unavailable.

Same Anesthesia Endoscopic Retrograde Cholangiopancreatography and Laparoscopic Cholecystectomy: The Pediatric ERCP Database Intiative Experience

BACKGROUND

Successful combined Laparoscopic cholecystectomy and endoscopic retrograde cholangiopancreatography (ERCP) in the Same Session (LESS) has been reported in several studies in adult patients with choledocholithiasis.

METHODS

This was a retrospective analysis of data collected prospectively in the Pediatric ERCP Database Initiative using REDCAP. Adverse events were recorded separately and were reviewed for this study. The primary outcome was the hospitalization days. Secondary outcomes included total duration of anesthesia, morbidity, time from diagnosis to procedure.

RESULTS

Twenty-five patients underwent LESS, and 42 underwent the traditional ERCP followed by laparoscopic cholecystectomy. The groups were similar in age, weight, ASA. The median length of stay in the LESS group was 3 days, compared with 4 days (P = .32). Total procedure time was similar between the 2 groups, but anesthesia time was shorter in the LESS group (P = .0401). Morbidity was similarly low between the 2 groups.

CONCLUSIONS

Relative to 2 interventions, a single session combining ERCP and laparoscopic cholecystectomy in pediatric patients is effective with a similar adverse event rate and length of stay. The use of a single sedation and reduced total anesthesia time are potential benefits of this approach. This modality may be considered for pediatric patients with choledocholithiasis with or without hemolytic disease.

Transductal versus transcystic laparoscopic common bile duct exploration: an institutional review of over four hundred cases

BACKGROUND

Many studies have failed to demonstrate significant differences between single- and two-staged approaches for the management of choledocholithiasis with concomitant gallstones in terms of post-operative morbidity. However, none of these studies paid specific attention to the differences between the methods of accessing the bile duct during laparoscopy. The aim of this study was to report outcomes of transcystic versus transductal laparoscopic common bile duct exploration (LCBDE) from our experience of over four hundred cases.

METHODS

Retrospective review of 416 consecutive patients who underwent LCBDE at a single-centre between 1998 and 2018 was performed. Data collected included pre-operative demographic information, medical co-morbidity, pre-operative investigations, intra-operative findings (including negative choledochoscopy rates, use of holmium laser lithotripsy and operative time) and post-operative outcomes.

RESULTS

Transductal LCBDE via choledochotomy was achieved in 242 patients (58.2%), whereas 174 patients (41.8%) underwent transcystic LCBDE. Stone clearance rates, conversion to open surgery and mortality were similar between the two groups. Overall morbidity as well as minor and major post-operative complications were significantly higher in the transductal group. The main surgery-related complications were bile leak (5.8% vs 1.1%, p = 0.0181) and pancreatitis (7.4% vs 0.6%, p = 0.0005). Median length of post-operative stay was also significantly greater in the transductal group.

CONCLUSION

This study represents the largest single study to date comparing outcomes from transcystic and transductal LCBDE. Where possibly, the transcystic route should be used for LCBDE and this approach can be augmented with various techniques to increase successful stone clearance and reduce the need for choledochotomy.

The clinical course of common bile duct stone clearance with endoscopic retrograde cholangio-pancreaticography

Objectives: Two-stage treatment of common bile duct stones by Endoscopic Retrograde Cholangio-Pancreatography and subsequent laparoscopic cholecystectomy is well established. In many cases multiple procedures are needed before clearance of the common bile duct is obtained. This study aimed to describe the clinical course from common bile duct stone diagnosis to successful clearance. Materials and Methods: A prospective observational study from 2011 to 2014 of consecutive patients diagnosed with common bile duct stones undergoing Endoscopic Retrograde Cholangio-Pancreatography at a public university hospital. Results: In this study 297 patients with common bile duct stones were identified. More than one Endoscopic Retrograde Cholangio-Pancreatography was performed in 174 (59%) patients and more than two in 51(17%) before clearance. A sphincterotomy was performed in 269 (91%) patients and 189 (64%) had a stent inserted. Bleeding occurred in 17 (6%) requiring injection treatment and post procedure complications occurred in 38 (13%). Subsequent laparoscopic cholecystectomy was performed in 180 (61%) patients. Overall, the patients were hospitalized for 11 (8.5) days and the length of treatment from diagnose to stone clearance was 49 (84.5) days. Overweight, pancreatitis at admission, universal anesthesia, and expert level endoscopist inversely determined common bile duct clearance failure. Conclusions: Common bile duct clearance by Endoscopic Retrograde Cholangio-Pancreatography requires multiple procedures and complications are frequent leading to prolonged treatment and hospitalization suggesting a limited efficacy.

Endoscopic retrograde cholangiopancreatography versus surgery for choledocholithiasis - A meta-analysis

INTRODUCTION AND OBJECTIVES

There is no consensus on the best treatment option for choledocholithiasis. Therefore, the aim of this study was to compare endoscopic retrograde cholangiopancreatography (ERCP) and common bile duct surgery (CBDS) for the treatment of choledocholithiasis.

MATERIALS AND METHODS

We performed a systematic review of randomized controlled trials (RCTs) comparing ERCP and CBDS in the treatment of choledocholithiasis. MEDLINE and EMBASE were the used databases. RCTs assessing mortality, bile duct clearance failure, complications, or length of hospital stay were considered eligible. Meta-analysis was performed using random effects model, through the Mantel-Haenszel method for binary outcomes and through the inverse variance method for continuous outcomes. The quality of the evidence was evaluated according to the Grading of Recommendations Assessment, Development and Evaluation Working Group. The study protocol was registered at the PROSPERO platform (CRD42017073196).

RESULTS

Nineteen RCTs (2466 patients) were included in the meta-analysis. There was no evidence of significant difference between interventions regarding mortality (risk ratio - RR=1.31, 95% confidence interval - 95% CI=0.60-2.85, p=0.49), bile duct clearance failure (RR=1.17, 95% CI=0.86-1.59, p=0.31), complications (RR=0.99, 95% CI=0.82-1.20, p=0.94) and length of hospital stay (weighted mean difference - MD=1.06, 95% CI=-0.62-2.73, p=0.22). Sensitivity analyses failed to demonstrate significant changes in results compared to the main analyses. The quality of the evidence was considered to be low.

CONCLUSION

There was no evidence of significant difference between ERCP and CBDS for the treatment of choledocholithiasis.

Role of Cholecystectomy After Endoscopic Sphincterotomy in the Management of Choledocholithiasis in High-risk Patients: A Systematic Review and Meta-Analysis

BACKGROUND

Endoscopic retrograde cholangiography and endoscopic sphincterotomy (ES) with subsequent cholecystectomy is the standard of care for the management of patients with choledocholithiasis. There is conflicting evidence in terms of mortality reduction, prevention of complications specifically biliary pancreatitis and cholangitis with the use of early cholecystectomy particularly in high-risk surgical and elderly patients.

AIMS

We conducted this systematic review and meta-analysis of randomized controlled trials to compare the early cholecystectomy versus wait and watch strategy after ES.

METHODS

We searched Medline, Scopus, Web of Science, and Cochrane database for randomized controlled trials comparing the 2 strategies in the management of choledocholithiasis after ES. Our primary outcome of interest was difference in mortality. We evaluated several secondary outcomes including difference in development of acute pancreatitis, biliary colic and cholecystitis, cholangitis and recurrent jaundice, nonbiliary adverse events, and length of hospital stay. Risk ratios (RR) were calculated for categorical variables and difference in means was calculated for continuous variables. These were pooled using random effects model.

RESULTS

Seven studies with 916 patients (455 cholecystectomy group and 461 wait and watch group) were included in the meta-analysis. Pooled RR with 95% confidence interval for mortality was 1.43 (0.93-2.18), I=9%. In the high-risk patient group, pooled RR was 1.39 (0.64-3.03) and in low-risk population pooled RR was 1.53 (0.79-2.96). Pooled RR for acute pancreatitis was 1.64 (0.46-5.81) with no heterogeneity. There was no difference in the rate of acute pancreatitis patients based on high-risk versus low-risk patients. Pooled RR for occurrence of biliary colic and cholecystitis during follow-up was 9.82 (4.27-22.59), I=0%. Pooled RR for cholangitis and recurrent jaundice was 2.16 (1.14-4.07), I=0%. However, there was no difference in the rate of cholangitis between the 2 groups in low-risk patients. Length of stay was shorter in the wait and watch group with a pooled mean difference was -2.70 (-4.71, -0.70) with substantial heterogeneity.

CONCLUSIONS

Although we found no difference in mortality between the 2 strategies after ES, laparoscopic cholecystectomy should be recommended as it is associated with lower rates of subsequent recurrent cholecystitis, cholangitis, and biliary colic down the road even in high-risk surgical patients.

Comparison of Efficacy and Safety of 4 Combinations of Laparoscopic and Intraoperative Techniques for Management of Gallstone Disease With Biliary Duct Calculi: A Systematic Review and Network Meta-analysis

Importance

Several techniques are used for surgical treatment of gallstone disease with biliary duct calculi, but the safety and efficacy of these approaches have not been compared.

Objectives

To compare the efficacy and safety of 4 surgical approaches to gallstone disease with biliary duct calculi.

Data Sources

MEDLINE, Scopus, and ISI-Web of Science databases, articles published between 1950 and 2017 and searched from August 12, 2017, to September 14, 2017. Search terms used were LCBDE, LC, preoperative, ERCP, postoperative, period, cholangiopancreatography, endoscopic, retrograde, rendezvous, intraoperative, one-stage, two-stage, single-stage, gallstone, gallstones, calculi, stone, therapy, treatment, therapeutics, surgery, surgical, procedures, clinical trials as topic, random, and allocation in several logical combinations.

Study Selection

Randomized clinical trials comparing at least 2 of the following strategies: preoperative endoscopic retrograde cholangiopancreatography (PreERCP) plus laparoscopic cholecystectomy (LC); LC with laparoscopic common bile duct exploration (LCDBE); LC plus intraoperative endoscopic retrograde cholangiopancreatography (IntraERCP); and LC plus postoperative ERCP (PostERCP).

Data Extraction and Synthesis

A frequentist random-effects network meta-analysis was performed. The surface under the cumulative ranking curve (SUCRA) was used to show the probability that each approach would be the best for each outcome.

Main Outcomes and Measures

Primary outcomes were the safety to efficacy ratio using overall mortality and morbidity rates as the main indicators of safety and the success rate as an indicator of efficacy. Secondary outcomes were acute pancreatitis, biliary leak, overall bleeding, operative time, length of hospital stay, total cost, and readmission rate.

Results

The 20 trials comprised 2489 patients (and 2489 procedures). Laparoscopic cholecystectomy plus IntraERCP had the highest probability of being the most successful (SUCRA, 87.2%) and safest (SUCRA, 69.7%) with respect to morbidity. All approaches had similar results regarding overall mortality. Laparoscopic cholecystectomy plus LCBDE was the most successful for avoiding overall bleeding (SUCRA, 83.3%) and for the shortest operative time (SUCRA, 90.2%) and least total cost (SUCRA, 98.9%). Laparoscopic cholecystectomy plus IntraERCP was the best approach for length of hospital stay (SUCRA, 92.7%). Inconsistency was found in operative time (indirect estimate, 19.05; 95% CI, 2.44-35.66; P = .02) and total cost (indirect estimate, 17.06; 95% CI, 3.56-107.21; P = .04). Heterogeneity was observed for success rate (τ, 0.8), operative time (τ, >1), length of stay (τ, >1), and total cost (τ, >1).

Conclusions and Relevance

The combined LC and IntraERCP approach had the greatest odds to be the safest and appears to be the most successful. Laparoscopic cholecystectomy plus LBCDE appears to reduce the risk of acute pancreatitis but may be associated with a higher risk of biliary leak.

Laparoscopic surgery for choledocholithiasis concomitant with calculus of the left intrahepatic duct or abdominal adhesions

BACKGROUND

Laparoscopic common bile duct exploration (LCBDE) has been widely promoted in recent years as a safe and effective treatment for choledocholithiasis. However, there are no standard guidelines for the treatment of patients who have concomitant hepatolithiasis of the left liver and abdominal adhesions. The aim of the current research was to compare the outcomes of open versus laparoscopic common bile duct exploration with left hepatectomy (OCBDH vs. LCBDH) in patients with choledocholithiasis concomitant with left-sided hepatolithiasis, and to evaluate the safety and feasibility of laparoscopic surgery for choledocholithiasis in patients with abdominal adhesions.

METHODS

Between October 2012 and October 2015, a total of 321 consecutive patients with choledocholithiasis underwent surgical treatment. LCBDE was performed in 107 patients, and open common bile duct exploration (OCBDE) was performed in 111 patients. Further, 31 patients and 72 patients underwent LCBDH and OCBDH, respectively. A total of 133 patients who underwent LCBDE or OCBDE had abdominal adhesions, which were classified as mild, moderate, or severe according to an abdominal adhesion scoring system, which was validated in the LCBDE group and OCBDE group. The perioperative results were reviewed and analyzed retrospectively.

RESULTS

In the mild adhesion group, blood loss, postoperative recovery in the LCBDE group was lesser than those in the OCBDE group. In the moderate adhesion group, the postoperative recovery was significantly shorter in the LCBDE group than in the OCBDE group. In the severe adhesion group, the operation time and blood loss in the LCBDE group were higher than those in the OCBDE group. The postoperative recovery was significantly better in the LCBDH group than in the OCBDH group.

CONCLUSION

LCBDH can obviously improve recovery and shorten the hospitalization period. Further, LCBDE is safe and feasible for patients of choledocholithiasis with mild and moderate abdominal adhesions.

Efficacy and safety of laparoscopic bile duct exploration versus endoscopic sphincterotomy for concomitant gallstones and common bile duct stones: A meta-analysis of randomized controlled trials

BACKGROUND

The purpose of this study was to compare the efficacy and safety of laparoscopic cholecystectomy (LC) plus laparoscopic common bile duct (CBD) stones exploration (LCBDE) with LC plus endoscopic sphincterotomy (EST) in the treatment of patients with gallstones and CBD stones.

METHODS

The authors searched PubMed, Web of Science, and Embase to identify relevant studies. Risk ratios (RRs) were pooled to compare stone clear, retained stone, conversion to other procedures, and complications. Weighted mean differences (WMDs) were pooled to compare operative time, and length of hospital stay. A fixed-effects model or random-effects model was used to pool the estimates, according to the heterogeneity among the included studies.

RESULTS

A total of 11 randomized controlled trials (RCTs) involving 1663 patients were included in this meta-analysis. The pooled estimate suggested that LC-LCBDE had comparable effects with LC-EST in terms of CBD stone clear rate (RR = 1.02, 95% CI: 0.95, 1.09; P = .583), retained stones rate (RR = 1.27, 95% CI: 0.51, 3.19; P = .607), and length of hospital stay (WMD = -0.96 days, 95% CI: -2.20, 0.28). In addition, LC-LCBDE was associated with significantly higher conversion rate (RR = 1.59, 95% CI: 1.08, 2.35; P = .019) and less operative time (WMD = -11.55 minutes, 95% CI: -16.68, -6.42; P < .001) than LC-EST. The incidence of complications was not significant difference between the 2 surgical approaches (RR = 1.07, 95% CI: 0.86, 1.34; P = .550).

CONCLUSION

Based on the current evidence, both LC-LCBDE and LC-EST were highly effective in detecting and removing CBD stones and were equivalent in complications. However, our results might be biased by the limitations. Large-scale well-designed RCTs are needed to confirm our findings.

Advantages of laparoscopic common bile duct exploration in common bile duct stones

OBJECTIVE

To compare the efficacy, safety, and surgical outcomes of laparoscopic common bile duct exploration, endoscopic retrograde cholangiopancreatography, and open common bile duct exploration for treatment of common bile duct stones.

METHODS

In total, 210 patients were prospectively randomized into 3 groups: laparoscopic common bile duct exploration, endoscopic retrograde cholangiopancreatography, and open common bile duct exploration. The primary outcome measures were the common bile duct stone clearance rate and the complication rate. The secondary outcome measures were mortality, total costs, and length of hospital stay.

RESULTS

The success rates in the laparoscopic common bile duct exploration group (97.14%, 68 out of 70) and open common bile duct exploration group (98.57%, 69/70) were significantly higher than that in the endoscopic retrograde cholangiopancreatography group (85.71%, 60/70, both p < 0.05). The complication rates in the laparoscopic common bile duct exploration group (2.86%, 2/70) and open common bile duct exploration group (1.43%, 1/70) were significantly lower than that in the endoscopic retrograde cholangiopancreatography group (14.29%, 10/70, both p < 0.05). The success rate and complication rate were not significantly different between the laparoscopic common bile duct exploration group and open common bile duct exploration group (both p > 0.05).

CONCLUSION

Laparoscopic common bile duct exploration provides an alternative therapeutic approach that was safer and more reliable, allowed for earlier recovery, and provided more cost-effective treatment of common bile duct stones.

Cost-analysis and effectiveness of one-stage laparoscopic versus two-stage endolaparoscopic management of cholecystocholedocholithiasis: a retrospective cohort study

BACKGROUND

One-stage laparoscopic common bile duct (CBD) stone clearance and laparoscopic cholecystectomy (LCBDE+LC) for cholecystocholedocholithiasis ( CCL) can be performed with similar short and long-term outcomes than two-stage endoscopic retrograde cholangiography followed by subsequent LC (ERCP+LC). This study examined retrospectively the outcome and hospital costs of one-stage versus two-stage treatment of CBD stones.

METHODS

From January 1999 and December 2014, 217 consecutive, elective patients underwent one-stage (LCBDE + LC ) or two-stage (ERCP + subsequent LC ) treatment for CBD stones. The data from the one-stage management was collected prospectively, and from the two-stage management retrospectively. The main measure of outcome was hospital costs, with the success of one-stage versus two-stage management, postoperative morbidity and postoperative stay as secondary outcome measures.

RESULTS

One-stage laparoscopic transcystic management was the least costly option compared to laparoscopic one-stage transductal approach (TC 5455€ versus TD 9364, p < 0.001) or two-stage management (6913 €, p = 0.02). Overall success rate of primary intervention (including conversions to open surgery) for CBD stone clearance was 96.9%, 97.0% and 98.3% after transcystic one-stage, transductal one-stage and two-stage approach, p = 0.79. Postoperative morbidity was 15.5% versus 7.5%, p = 0.64, and postoperative hospital stay median 2 days (IQR 2-5) versus 4.5 days ( IQR 3-7), p < 0.001 in the one-stage and two-stage management groups.

CONCLUSIONS

Our study shows that laparoscopic one-stage transcystic management of CCL results in high rate of CBD clearance, fewer procedures per patient, shorter hospital and lower costs than the two-stage management. Therefore the one-stage transcystic management seems to be an attractive strategy for the treatment of CCL depending on local resources and surgical expertise .

Management of suspected common bile duct stones on cholangiogram during same-stay cholecystectomy for acute gallstone-related disease

BACKGROUND

Recent data have suggested that upfront cholecystectomy should be performed even in the presence of moderately abnormal liver function tests (LFTs). As a consequence, more common bile duct (CBD) stones are discovered on intra-operative cholangiogram. We assessed the presentation and management of such patients to refine their management plan.

METHODS

Adult patients (>16 years) with an acute gallstone-related disease who had undergone same-stay cholecystectomy from January 2013 to January 2015 were retrospectively assessed. We excluded patients with pre-operative endoscopic CBD exploration.

RESULTS

Among the 612 patients with same-stay cholecystectomy, 399 patients were included in the study, and 213 were excluded because of a pre-operative CBD exploration. Fifty patients (12.5%) presented an image of CBD stone on the intra-operative cholangiogram. Such patients were younger (47 vs. 55 years, P = .01) and less likely to present with fever (1 vs. 11.7%, P = .04) or signs of cholecystitis on ultrasound (66 vs. 83.7%, P = .003). Admission LFTs were higher in patients with an image of a stone. Among the 50 patients with an image on cholangiogram, a stone was confirmed in 26 (52%). Most patients (n = 32) underwent post-operative assessment with endoscopic ultrasound (EUS). LFTs did not predict the presence of a confirmed stone. However, the absence of contrast passage into the duodenum was negatively associated with a confirmed stone (P = .08), and a filling defect was positively associated with one (P = .11). Most confirmed stones were successfully extracted by endoscopic retrograde cholangiopancreatogram (ERCP) (25/26, 96%), except in one patient who needed a per-cutaneous approach because of duodenal diverticuli.

CONCLUSIONS

Same-stay cholecystectomy can (and should) be performed even in the presence of moderately abnormal liver function tests. The cholangiogram suspicion of a CBD stone is confirmed in only half of the patients (more often in the presence of a filling defect, and less often with the absence of contrast passage). All stones can be safely treated after surgery (most by ERCP).

Utility of MRCP in clinical decision making of suspected choledocholithiasis: An institutional analysis and literature review

BACKGROUND

The ideal treatment algorithm for suspected choledocholithiasis is not yet well defined. Imaging options include magnetic resonance cholangiopancreatography (MRCP), endoscopic retrograde cholangiopancreatography (ERCP), and intraoperative cholangiogram (IOC). MRCP is diagnostic, while the other two modalities can also be therapeutic. Each of these modalities for diagnosis and treatment carries its own set of risks, benefits, and institutional costs. We hypothesized that there would be a significant difference between the biochemical profiles and characteristics of patients who undergo ERCP vs. MRCP vs. operative intervention as the initial choice of treatment/imaging modality.

METHODS

We performed a retrospective review of the electronic medical records for all patients with a coded diagnosis of choledocholithiasis from 2011 to 2014. The initial diagnostic modality was assessed for each hospital encounter. The statistical characteristics of MRCP as compared to fluoroscopic imaging of the biliary tree (ERCP, IOC) were analyzed.

RESULTS

Overall, 527 hospital encounters were identified. Initial intervention included ERCP in 63%, MRCP in 12%, and cholecystectomy in 25% of patients. Patients undergoing cholecystectomy first, compared to MRCP or ERCP, tended to have lower values for alkaline phosphatase (P < 0.001) and AST (P = 0.002) as well as be of younger age (P < 0.0001). Of the patients that underwent MRCP as their initial procedure, 82% subsequently underwent either ERCP or laparoscopic cholecystectomy. In patients who underwent an initial MRCP followed by either ERCP or IOC, the predictive performance of MRCP was as follows: sensitivity = 0.90, specificity = 0.86, positive predictive value = 0.97, negative predictive value = 0.60, agreement (Cohen's Kappa) = 0.64.

CONCLUSIONS

There is a significant difference in the laboratory evaluation and demographics of patients undergoing ERCP, MRCP, and laparoscopic cholecystectomy. MRCP was followed with a more invasive test a majority of the time. Since MRCP did not change the management of patients with suspected choledocholithiasis, its utility in this patient population should be questioned. Further research is needed to better define the pretest characteristics which would predict which patients do not need further intervention after MRCP as well as defining the most cost-effective strategy.
