Endoscopic Papillary Large Balloon Dilation Reduces Further Recurrence in Patients With Recurrent Common Bile Duct Stones: A Randomized Controlled Trial

Structural or functional abnormality of sphincter of Oddi: an important factor for the recurrence of choledocholithiasis after endoscopic treatment

A high recurrence rate is undesirable after treatment of common bile duct (CBD) stones. A major risk factor identified for recurrence is that invasive techniques, including surgical or endoscopic treatments, will impair the biliary tract system either by direct incision of the CBD or by cutting or dilating the ampulla of Vater. During endoscopic treatment, two main assisted methods for lithotomy, sphincterotomy and papillary balloon dilation, can result in different degrees of damage to the structure and function of the sphincter of Oddi (SO), contributing to slowing of biliary excretion, cholestasis, biliary bacterial infection, and promotion of bile duct stone recurrence. In this review, the relationship between endoscopic lithotomy and structural impairment or functional abnormality of the SO will be summarized, and their relationship with the recurrence of CBD stones will also be analyzed. Further improvement of these endoscopic methods or exploration of some novel methods, such as endoscopic endoclip papilloplasty, temporary insertion of a self-expandable metal stent, and combined application of peroral cholangioscopy, may aid in providing more appropriate treatment for patients with choledocholithiasis, repair or protect the function and structure of SO, reduce or prevent the recurrence of bile duct stones, and improve patient outcomes.

Treatment for recurrent choledocholithiasis: endoscopic? or laparoscopic? A prospective cohort study

BACKGROUND

Endoscopic and laparoscopic techniques are crucial for management of bile duct stone.

OBJECTIVE

The aim of this study was to share our initial experiences with endoscopic and laparoscopic treatments for recurrent choledocholithiasis, with a particular focus on long-term complications.

METHODS

From January 2014 to June 2017, a total of 153 patients with recurrent common bile duct stones were prospectively recruited in this study. Patients were scheduled for either an endoscopic procedure (ERCP/EST group, n = 84), or a laparoscopic procedure (LCBDE group, n = 69). Data were collected on comorbid conditions, presenting symptoms, bile duct clearance, and the incidence of both short-term and long-term complications.

RESULTS

Patients in ERCP/EST group had a stone clearance rate comparable to that of the LCBDE group (94.2% vs 91.7%, p = 0.549). Minor (Clavien-Dindo grade 1 and 2) and major short-term complications (Clavien-Dindo grade 3 and above) were similar between patients in two groups (ERCP/EST group 17.9% versus LCBDE group 26.1%, and ERCP/EST group 7.1% versus LCBDE group 5.8%, p = 0.227 and p = 0.740, respectively). Patients in the ERCP/EST group had a shorter stone free interval than patients in the LCBDE group (28.5 ± 14.7 months versus 43.3 ± 17.8 months, p = 0.029). During a mean follow-up period of 67.0 months, more patients in the ERCP/EST group experienced stone recurrence compared to those in the LCBDE group (26.1% vs 11.6%, p = 0.020). In the ERCP/EST group, 45.5% (10/22) of the recurrent cases experienced more than two recurrences, with three patients requiring choledochojejunostomy due to repeated recurrence. Among patients with a non-dilated common bile duct (d ≤ 8 mm), both groups had comparable short-term and long-term complication rates (p = 0.151 and p = 0.404, respectively).

CONCLUSIONS

Laparoscopic treatment is a safe and effective option for patients with recurrent choledocholithiasis, extending the stone free interval, reducing the likelihood of stone recurrence, and highlighting benefits of minimally invasive surgery.

Endoscopic Papillary Large Balloon Dilatation With or Without Endoscopic Sphincterotomy in the Treatment of Common Bile Duct Stones

PURPOSE OF REVIEW

Endoscopic papillary large balloon dilation (EPLBD) has been proved to have better efficacy and safety in removing common bile duct stones. Conventional endoscopic sphincterotomy (EST) is usually performed before EPLBD. However, EPLBD without EST has recently reported short-term outcomes similar to those of EPLBD with EST. This article summarizes the latest research advances in EPLBD with or without EST for the treatment of large common bile duct stones (CBDS) as a way to provide further evidence to support the ERCP surgeon's choice of which technique to use for the treatment of large CBDS.

FINDINGS

EPLBD alone is recommended in cases of anatomical abnormalities or bleeding tendencies. EPLBD with EST is recommended in patients with stenosis of the duodenal papilla or distal common bile duct or with periportal diverticula. Most clinical studies have shown that the clinical efficacy and incidence of adverse events associated with ESLBD are comparable to those of standalone EPLBD. However, further large-scale prospective randomized controlled trials are needed to confirm these findings.

Large balloon sphincteroplasty for CBD stone removal during acute cholangitis. Single center propensity-score matched cohort study

BACKGROUND

Endoscopic biliary drainage is the mainstay of treatment for acute cholangitis. CBD stone removal can be performed in same session with biliary drainage. Our team incorporated the use of endoscopic large balloon sphincteroplasty as an alternative for conventional papillotomy for biliary access. This study aims to identify tips and pitfalls of EPLBD usage during acute cholangitis.

METHOD

From the period October 2016 to April 2021, Yan Chai Hospital has 209 patients presented with acute cholangitis had ERCP for CBD stone removal performed. Among which, 50 patients had limited papillotomy followed by endoscopic large balloon papillary dilatation for biliary access (EPLBD), while 159 patients had conventional sphincterotomy (EST) done. Propensity score matching analysis was performed in a 1:1 ratio. Primary outcome was complete CBD stone removal as defined by clearance of occlusive cholangiogram. Secondary outcomes are post-ERCP pancreatitis, minor bleeding and major bleeding, flare up of sepsis. Logistic regression analysis was performed to identify risk factors associated with one year recurrence rate. Kaplan Meier analysis was utilized for long-term recurrence rate after ERCP.

RESULT

In overall cohort, presence of large CBD stone & parapapillary diverticulum was more frequent in EPLBD group (26.0 ≤ 6.2% vs 9.4 ± 2.3%, p = 0.003) & (52.0 ± 7.1% vs 24.5 ± 3.4%, p < 0.001); they were balanced in PSM cohort. The complete CBD stone removal rate were higher in EPLBD group than EST group with statistical significance (80.0 ± 5.7% vs 54.0 ± 7.0%, p = 0.006). Major bleeding requiring reintervention was observed in 2.0 ± 2.0% vs 8.0 ± 3.8%, p = 0.169. Post ERCP pancreatitis were observed in 2.3 ± 2.2% vs 2.4 ± 2.4%, p = 0.960. 1 year recurrence rate was 14.0 ± 4.9% vs 2.0 ± 2.0 % , p = 0.027 .

CONCLUSION

Deployment of EPLBD during acute cholangitis demonstrated clinical efficacy in CBD stone clearance when compared with conventional sphincterotomy with a non-inferior safety profile. However, long term recurrence rate of acute cholangitis was observed to be higher.

Comparison of the efficacy of LTCBDE and LCBDE for common bile duct stones: a systematic review and meta-analysis

Background

The choice of surgical methods for common bile duct stones (CBDS) is controversial. The aim of this study was to compare the safety and efficacy of laparoscopic transcystic common bile duct exploration (LTCBDE) and laparoscopic common bile duct exploration (LCBDE).

Methods

Relevant literature published before March 30, 2023 in PubMed, Web of Science, Embase, and Cochrane was searched to screen studies comparing LTCBDE and LCBDE. RevMan 5.4 was used for meta-analysis of fixed-effects and random-effects models.

Results

A total of 21 studies met the inclusion criteria, including 3065 patients in the LTCBDE group and 2,453 patients in the LCBDE group. CBDS clearance was 95.4% (2,682/2,812) in LTCBDE group and 94.7% (1,810/1,911) in LCBDE group (OR: 1.84, 95% CI: 1.36, 2.48, P < 0.0001; I 2 = 0%, P = 0.56). In LTCBDE group, operative time(MD = -34.60, 95% CI: -46.05, -23, 15, P < 0.00001 I 2 = 96%, P < 0.00001), postoperative hospital stay (MD = -2.92, 95% CI: -3.62, -2.21, P < 0.00001; I 2 = 92%, P < 0.00001), postoperative complications (OR: 0.47, 95% CI: 0.38, 0.58, P < 0.0001; I 2 = 26%, P = 0.15), residual stone(OR: 0.48, 95% CI: 0.34, 0.66, P < 0.0001; I 2 = 0%, P = 0.56), bile leak (OR: 0.37, 95% CI: 0.25, 0.55, P < 0.00001; I 2 = 0%,P = 0.52), mortality (OR: 0.10, 95% CI: 0.01, 0.88, P = 0.04; I 2 = 0%, P = 0.71) and recurrent stones(OR: 0.34, 95% CI: 0.15, 0.74, P = 0.007; I 2 = 5%, P = 0.38) were better than LCBDE group. There was no difference in pancreatitis (OR: 1.06, 95% CI: 0.52, 2.16. P = 0.86; I 2 = 0%, P = 0.98) and biliary stricture(OR: 0.30, 95% CI: 0.08, 1.09, P = 0.07; I 2 = 0%, P = 0.57).

Conclusions

LTCBDE is safe, efficient, and of great clinical significance, and is worth promoting to some patients.

Orlando Protocol for single session ductal clearance of common bile duct stones at endosopic retrograde cholangiopancreatography

OBJECTIVES

Approach to management of common bile duct stones (CBDS) by endoscopic retrograde cholangiopancreatography (ERCP) is not standardized. We examined outcomes by applying predetermined protocol for CBDS management.

METHODS

When standard extraction techniques failed at ERCP, presence of tapered bile duct and stone-duct ratio were calculated. Large balloon sphincteroplasty (LBS) and/or mechanical/single-operator cholangioscopy-guided lithotripsy was performed based on presence of tapered bile duct and stone-duct mismatch. Primary outcome was single-session ductal clearance. Secondary outcome was adverse events.

RESULTS

Of 409 patients treated over 16 months, 321 (78.5%) had no tapered bile duct or stone-duct mismatch, and single-session ductal clearance was achieved using standard techniques in 99.7% over median duration of 14 min (interquartile range [IQR] 9-21 min). Of 88 (21.5%) patients with difficult CBDS, tapered duct was seen in 79 (89.8%) and/or stone-duct mismatch in 36 (40.9%). Single-session ductal clearance was achieved in all 88 patients (100%) by LBS in 79 (89.8%), mechanical lithotripsy in 20 (22.7%), and single-operator cholangioscopy-guided lithotripsy in 16 (18.2%) over a median duration of 29 min (IQR 17-47 min). Overall, single-session ductal clearance was achieved in 99.8% with adverse events in 17 (4.2%) that included perforation in two, postsphincterotomy bleeding in one, and mild/moderate post-ERCP pancreatitis in 14 patients.

CONCLUSIONS

A predetermined protocol optimized outcomes by enabling single-session ductal clearance of CBDS with high technical success and low adverse events.

Long-term prognosis and risk factors associated with post-ERCP pneumobilia in patients with common bile duct stones

BACKGROUND AND AIMS

Post-ERCP pneumobilia is not uncommon; however, studies focusing on the long-term prognosis of patients with post-ERCP pneumobilia are limited. This study aimed to explore long-term prognosis and risk factors associated with post-ERCP pneumobilia in patients with common bile duct stones (CBDSs).

METHODS

We conducted a retrospective analysis of 1380 patients who underwent ERCP for CBDSs at our hospital from January 2010 to December 2017. Patients were selected based on inclusion and exclusion criteria and divided into pneumobilia and nonpneumobilia groups, followed by propensity score matching. The matched groups were then compared in terms of incidence rates of both single and multiple recurrences of CBDSs, acute cholangitis, and acute cholecystitis. Multivariate logistic regression analysis was used to explore risk factors associated with pneumobilia.

RESULTS

After propensity matching, there was no significant difference in the rate of single recurrence of CBDSs (22.5% vs 30%; P = .446) between the pneumobilia and nonpneumobilia groups. However, the incidences of multiple recurrences of CBDSs (32.5% vs 12.5%; P = .032) and acute cholangitis without stone recurrence (32.5% vs 2.5%; P = <.001) were significantly higher in the pneumobilia group. Based on multivariate logistic regression analysis, in addition to a dilated CBD (diameter of >1 cm) (odds ratio [OR], 2.48; 95% confidence interval [CI], 1.03-3.76; P = .043), endoscopic sphincterotomy with moderate incision (OR, 5.38; 95% CI, 1.14-25.47; P = .034) and with large incision (OR, 8.7; 95% CI, 1.83-41.46; P = .007) were identified as independent risk factors for pneumobilia after initial ERCP.

CONCLUSIONS

Patients with post-ERCP pneumobilia have increased risk of multiple recurrences of CBDSs and acute cholangitis without stone recurrence. Independent risk factors for pneumobilia include peripapillary diverticulum, a dilated CBD (>1 cm), and endoscopic sphincterotomy with moderate and large incisions. A normal-sized CBD appears to serve as a secondary barrier against enterobiliary reflux, necessitating further research for confirmation.

Current management of concomitant cholelithiasis and common bile duct stones

The management policy of concomitant cholelithiasis and choledocholithiasis is based on a one- or two-stage procedure. It basically includes either laparoscopic cholecystectomy (LC) with laparoscopic common bile duct (CBD) exploration (LCBDE) in the same operation or LC with preoperative, postoperative and even intraoperative endoscopic retrograde cholangiopancreatography-endoscopic sphincterotomy (ERCP-ES) for stone clearance. The most frequently used worldwide option is preoperative ERCP-ES and stone removal followed by LC, preferably on the next day. In cases where preoperative ERCP-ES is not feasible, the proposed alternative of intraoperative rendezvous ERCP-ES simultaneously with LC has been advocated. The intraoperative extraction of CBD stones is superior to postoperative rendezvous ERCP-ES. However, there is no consensus on the superiority of laparoendoscopic rendezvous. This is equivalent to a traditional two-stage procedure. Endoscopic papillary large balloon dilation reduces recurrence. LCBDE and intraoperative ERCP have similar good outcomes. The risk of recurrence after ERCP-ES is greater than that after LCBDE. Laparoscopic ultrasonography may delineate the anatomy and detect CBD stones. The majority of surgeons prefer the transcductal instead of the transcystic approach for CBDE with or without T-tube drainage, but the transcystic approach must be used where possible. LCBDE is a safe and effective choice when performed by an experienced surgeon. However, the requirement of specific equipment and advanced training are drawbacks. The percutaneous approach is an alternative when ERCP fails. Surgical or endoscopic reintervention for retained stones may be needed. For asymptomatic CBD stones, ERCP clearance is the first-choice method. Both one-stage and two-stage management are acceptable and can ensure improved quality of life.
