Recurrence of biliary symptoms after endoscopic sphincterotomy for choledocholithiasis in patients with gall bladder stones

Laparoscopic Transcystic SpyGlass Discover-Assisted Common Bile Duct Exploration and Clearance: An Efficient and Cost-Effective Alternative for Common Bile Duct Stone Management

Aim This study aimed to assess the safety and efficacy of laparoscopic transcystic SpyGlass Discover (Boston Scientific Corporation, Marlborough, MA, USA) common bile duct (CBD) exploration combined with laparoscopic cholecystectomy (LC) as a single-stage procedure for patients requiring cholecystectomy and confirmed, suspected, or complex CBD stones. The study also evaluated the cost-effectiveness of this single-stage procedure compared to the two-stage endoscopic retrograde cholangiopancreatography (ERCP) followed by LC. The study adhered to the local clinical governance unit protocol and the Strengthening the Reporting of Cohort Studies in Surgery (STROCSS) guidelines. Materials and methods This is a retrospective cohort study conducted from January 2023 to July 2024. The safety, efficacy, and cost-effectiveness of SpyGlass Discover CBD exploration performed by a single consultant were evaluated. Of the sample population, 38 patients who underwent CBD stone management were included. Twenty-one patients (Group 1) had SpyGlass Discover CBD exploration planned, while 17 patients (Group 2) underwent the conventional preoperative ERCP followed by LC. All adult patients undergoing planned management were included. Data for comparison included age, gender, length of hospital stay, operative time, and success rates. Results Twenty-one patients underwent a single-stage operation using SpyGlass Discover. In nine cases, CBD exploration was performed, but no intervention was needed. In five cases, intervention was required, consisting of two laser lithotripsies and two mechanical lithotripsies with a basket. Seven cases had OTC, which showed a clear duct. The total operative time for Group 1 was 146 minutes on average. For those who did not require intervention, the mean operative time was 117 minutes, while the mean operative time for cases requiring intervention was 175 minutes. In Group 2, the mean operative time for ERCP + LC was 131 minutes. The length of hospital stay for Group 1 averaged 1.25 days, while Group 2 had an average of 1.52 days. Conclusions It was concluded that one-stage LC combined with SpyGlass Discover-assisted transcystic CBD clearance is an effective, safe, and cost-effective procedure when performed by skilled hands.

One-Stage Intraoperative ERCP combined with Laparoscopic Cholecystectomy Versus Two-Stage Preoperative ERCP Followed by Laparoscopic Cholecystectomy in the Management of Gallbladder with Common Bile Duct Stones: A Meta-analysis

INTRODUCTION

Concomitant gallbladder and common bile duct (CBD) stones, known as cholecystocholedocholithiasis, are clinically prevalent. There is currently no consensus on sequential versus simultaneous management approaches, and, if simultaneous, which approach to adopt. This meta-analysis evaluates the safety and efficacy of one-stage laparoscopic cholecystectomy (LC) with intraoperative endoscopic retrograde cholangiopancreatography (ERCP) versus two-stage ERCP followed by LC for treating concomitant gallbladder and CBD stones.

METHODS

A comprehensive literature search was conducted in five databases, PubMed, Embase, Web of Science, VIP, and Wanfang, for all randomized controlled trials (RCTs), cohort and retrospective studies published up to February 2024. Data extraction was performed independently by two reviewers. The primary outcomes were CBD stone clearance rate and postoperative complications morbidity. Secondary outcomes included conversion to other procedures and length of hospital stay. Statistical analyses were performed using R (v.4.3.2) with weighted mean differences and odds ratios (ORs) calculated for continuous and dichotomous variables, respectively, with 95% confidence intervals (CIs).

RESULTS

A total of 17 studies involving 2120 patients have been included, with 898 patients receiving single-stage and 1222 patients undergoing two-stage treatment. Of these studies, 9 were RCTs and 8 were retrospective cohort study. The one-stage group demonstrated superior outcomes in terms of CBD stone clearance (OR = 2.07, p = 0.0004), overall morbidity (OR = 0.35, p < 0.0001), post-operative pancreatitis (OR = 0.49, p = 0.006), conversion to other procedures (OR = 0.38, p = 0.0006), and length of hospital stay (MD = - 2.6456, 95% CI - 3.5776; - 1.7136, p < 0.0001). No significant differences were observed in post-operative cholangitis (OR = 0.44, p = 0.12), post-operative bleeding (OR = 0.76, p = 0.47), or bile leakage (OR = 1.28, p = 0.54).

CONCLUSION

For patients with concomitant gallbladder and CBD stones, the one-stage approach combining ERCP and LC appears safer and more effective, with advantages including higher stone clearance rates, reduced postoperative complications (particularly pancreatitis), shorter hospital stays, fewer residual stones, and decreased need for additional procedures. However, additional high-quality clinical trials are needed to establish the optimal treatment approach for various patient scenarios.

Is early laparoscopic cholecystectomy after clearance of common bile duct stones by endoscopic retrograde cholangiopancreatography superior?: A systematic review and meta-analysis of randomized controlled trials

BACKGROUND

With medical advancement, common bile duct stones were treated by endoscopic retrograde cholangiopancreatography (ERCP), considered the standard treatment. However, ERCP might induce complications including pancreatitis and cholecystitis that could affect a subsequent laparoscopic cholecystectomy (LC), leading to conversion to open cholecystectomy perioperative complications. It is not yet known whether or not the time interval between ERCP and LC plays a role in increasing conversion rate and complications. Bides, in the traditional sense, after ERCP, for avoiding edema performing LC was several weeks later. Even no one study could definite whether early laparoscopic cholecystectomy after ERCP affected the prognosis or not clearly.

OBJECTIVE

Comparing some different surgical timings of LC after ERCP.

METHOD

Searching databases consist of all kinds of searching tools, such as Medline, Cochrane Library, Embase, PubMed, etc. All the included studies should meet the demands of this meta-analysis. In all interest outcomes below, we took full advantage of RevMan5 and WinBUGS to assess; the main measure was odds ratio (OR) with 95% confidence. Moreover, considering the inconsistency of the specific time points in different studies, we set a subgroup to analyze the timing of LC after ERCP. For this part, Bayesian network meta-analysis was done with WinBUGS.

RESULT

In the pool of conversion rate, the result suggested that the early LC group was equal compared with late LC (OR = 0.68, I2 = 0%, P = .23). Besides, regarding morbidity, there was no significant difference between the 2 groups (OR = 0.74, I2 = 0%, P = .26). However, early LC, especially for laparoscopic-endoscopic rendezvous that belonged to performing LC within 24 hours could reduce the post-ERCP pancreatitis (OR = 0.16, I2 = 29%, P = .0003). Considering early LC included a wide time and was not precise enough, we set a subgroup by Bayesian network, and the result suggested that performing LC during 24 to 72 hours was the lowest conversion rate (rank 1: 0%).

CONCLUSION

In the present study, LC within 24 to 72 hours conferred advantages in terms of the conversion rate, with no recurrence of acute cholecystitis episodes.

Primary closure combined with C-tube drainage through cystic duct after laparoscopic common bile duct exploration is safe and feasible for patients

OBJECTIVE

Biliary duct management is of great significance after laparoscopic cholecystectomy (LC) combined with laparoscopic common bile duct exploration (LCBDE) in the treatment of cholecystolithiasis accompanied with common bile duct (CBD) stones. This study is to evaluate the safety and effectiveness of primary closure with C-tube drainage through cystic duct after LC + LCBDE.

METHODS

Through a retrospective study, 290 patients who underwent LC + LCBDE in our hospital from January 2019 to April 2022 were enrolled and divided into 2 groups. 143 patients underwent primary closure with C-tube drainage through cystic duct (C-tube group) and the other 147 patients underwent traditional T-tube drainage (T-tube group). Personal information, perioperative examinations, surgical results, and follow-up results were collected and analyzed.

RESULTS

There were no significant differences in the average age, gender, the mean of CBD diameters and the rate of comorbidities (acute cholecystitis, obstructive jaundice, acute pancreatitis and acute cholangitis) between the two groups (P > 0.05). Hospital stay, postoperative hospital stay were significantly shorter in the C-tube group than T-tube group (P < 0.05). In addition, the average time of placing and removal the drainage tubes was significantly less than those of the T-tube group (P < 0.05). This study also showed significant differences in the incidence of postoperative abdominal infection and soft tissue infection in the two groups (P < 0.05). There were no significant differences in the incidence of postoperative complications including cholangitis, bile duct stenosis, mortality in two groups. There were also no significant differences between the two groups of the recurrence of CBD stones, reoperation and readmition in 30 days during the median follow-up of 6 months.

CONCLUSIONS

Compared with T tube drainage, patients with C-tube drainage after LC + LCBDE with primary closure of cystic duct recovered faster and had fewer complications. C-tube drainage is a safe and feasible treatment option for patients with cholecystolithiasis and choledocholithiasis.

Predictors for stone recurrence after a successful common bile duct surgical exploration for choledocholithiasis

BACKGROUND

Recurrence after common bile duct stone (CBDS) clearance is the major long-term drawback of their management. Its prevalence is significant, and it occurs after all primary therapeutic alternatives. The aim of this study was to determine the predictive factors associated with stone recurrence after surgical common bile duct exploration (CBDE).

METHODS

A retrospective cohort study based on patients undergoing CBDE between 2000 and 2018 was conducted. Uni- and multivariate hierarchical regression analyses were performed to assess the independent predictive factors associated with recurrent CBDS in patients with initially successful surgery.

RESULTS

A total of 365 patients underwent successful surgical procedures. After a median follow-up of 43.2 (IQR 84) months, 31 (8.4%) patients were diagnosed with CBD stone recurrence. The median time to recurrence was 30.3 (IQR 38) months. The only variable associated with CBDS recurrence was preoperative endoscopic sphincterotomy (HR 2.436, 95% CI: 1.031-5.751, P = 0.042)).

CONCLUSION

Patients who undergo preoperative endoscopic sphincterotomy and then cholecystectomy with successful common bile duct clearance may be at increased risk for recurrent stone disease compared to those who go straight to surgery.

What makes acute cholecystitis recur after removing the percutaneous cholecystostomy tube?

Percutaneous transhepatic gallbladder drainage (PTGBD) is an alternative treatment option for acute cholecystitis. However, the disease may recur after PTGBD catheter removal. This study aimed to evaluate the role of endoscopic sphincterotomy and other risk factors in reducing the recurrence of cholecystitis.We retrospectively analyzed data from 1088 patients who underwent PTGBD for cholecystitis at Kyungpook National University Hospital, Republic of Korea, between January 2011 and April 2018.A total of 115 patients were enrolled in the study. The recurrence rate of cholecystitis was 17.4% (n = 20) during a median follow-up period of 1159 (range, 369-2774) days. Endoscopic biliary sphincterotomy did not significantly affect the recurrence rate of cholecystitis (P = .561). In multivariable analysis, cystic duct stones (P = .013) and PTGBD catheter migration before the prescheduled removal time (P = .002) were identified as independent risk factors for cholecystitis recurrence after PTGBD.To reduce post-PTGBD recurrence in cholecystitis, caution must be exercised to avoid inadvertent dislodging of the PTGBD catheter. In cases of cholecystitis with cystic duct stones, cholecystectomy should be considered only after careful assessment of postoperative risks. Instead, transluminal endoscopic gallbladder drainage could represent a promising option for the prevention of recurrent cholecystitis.

Management of cholelithiasis with choledocholithiasis: Endoscopic and surgical approaches

Gallstone disease and complications from gallstones are a common clinical problem. The clinical presentation ranges between being asymptomatic and recurrent attacks of biliary pain requiring elective or emergency treatment. Bile duct stones are a frequent condition associated with cholelithiasis. Amidst the total cholecystectomies performed every year for cholelithiasis, the presence of bile duct stones is 5%-15%; another small percentage of these will develop common bile duct stones after intervention. To avoid serious complications that can occur in choledocholithiasis, these stones should be removed. Unfortunately, there is no consensus on the ideal management strategy to perform such. For a long time, a direct open surgical approach to the bile duct was the only unique approach. With the advent of advanced endoscopic, radiologic, and minimally invasive surgical techniques, however, therapeutic choices have increased in number, and the management of this pathological situation has become multidisciplinary. To date, there is agreement on preoperative management and the need to treat cholelithiasis with choledocholithiasis, but a debate still exists on how to cure the two diseases at the same time. In the era of laparoscopy and mini-invasiveness, we can say that therapeutic approaches can be performed in two sessions or in one session. Comparison of these two approaches showed equivalent success rates, postoperative morbidity, stone clearance, mortality, conversion to other procedures, total surgery time, and failure rate, but the one-session treatment is characterized by a shorter hospital stay, and more cost benefits. The aim of this review article is to provide the reader with a general summary of gallbladder stone disease in association with the presence of common bile duct stones by discussing their epidemiology, clinical and diagnostic aspects, and possible treatments and their advantages and limitations.

Medium and long-term complications difference between laparoscopic transcystic common bile duct exploration versus endoscopic sphincterotomy against choledocholithiasis: A protocol for systematic review and meta-analysis

BACKGROUND

Common bile duct stone (CBDS) is typically manifested with abdominal pain, chills, fever, and jaundice. Laparoscopic transcystic common bile duct exploration (LTCBDE) and endoscopic sphincterotomy (EST) are currently the main minimally invasive methods for the treatment of CBDS. However, there are few studies about the differences of medium and long-term complication after EST or LTCBDE. Therefore, we will conduct a meta-analysis and systematic review to systematically evaluate the difference of medium and long-term complications between EST and LTCBDE against CBDS.

METHODS

Randomized controlled trials of EST or LTCBDE against CBDS will be searched in several English and Chinese databases with the following vocabularies: "laparoscopic transcystic common bile duct exploration," "endoscopic sphincterotomy," "choledocholithiasis," "common bile duct stone" until December, 2020. Two reviewers will independently conduct the literature extraction, risk of bias assessment, and statistical analysis.

RESULTS AND CONCLUSIONS

The study will help to systematically evaluate the difference of medium and long-term complication between EST and LTCBDE against CBDS.

Long-term outcome and recurrence factors after percutaneous cholecystostomy as a definitive treatment for acute cholecystitis

BACKGROUND AND AIM

Percutaneous cholecystostomy (PC) has been frequently used as an alternative treatment for acute cholecystitis in seriously ill patients unfit for surgery. The aim of this study was to investigate the recurrence rate and risk factors of recurrence.

METHODS

Medical records of 102 patients who were followed up for more than 1 year after PC tube removal among 716 patients who underwent PC for acute cholecystitis treatment were retrospectively analyzed.

RESULTS

The recurrence rate of acute cholecystitis after PC tube removal was 20.6% (21/102), and the mean time to recur was 660 days. Underlying cancer (odds ratio [OR]: 3.369; 95% confidence interval [CI]: 1.006-11.282; P = 0.0489), PC duration shorter than 44 days (OR: 5.596; 95% CI: 1.35-23.201; P = 0.0176), and the presence of common bile duct stone in initial imaging studies (OR: 24.393; 95% CI: 2.696-220.746; P = 0.0045) were positively correlated with recurrence. Tubogram before PC tube removal did not significantly lower the recurrence. However, PC tube clamping for several days significantly lowered the recurrence (OR: 0.108; 95% CI: 0.015-0.794; P = 0.0288). Fifty-nine (57.8%) had acalculous cholecystitis. Calculous cholecystitis was negatively correlated with recurrence (OR: 0.267; 95% CI: 0.074-0.967; P = 0.0444). Receiver operating characteristic curve of the prediction model for recurrence verified its accuracy (area under the curve: 0.8475).

CONCLUSION

We should try to keep PC more than 6 weeks and clamp for 1-2 weeks before removal. For those with the presence of common bile duct stones, calculous cholecystitis, and underlying malignancy, we should keep PC for longer duration and carefully observe symptoms and signs of recurrence.

Ultrathin choledochoscope improves outcomes in the treatment of gallstones and suspected choledocholithiasis

BACKGROUND

We aimed to compare laparoscopic cholecystectomy (LC) and simultaneous laparoscopic transcystic common bile duct exploration (LTCBDE) using an ultrathin choledochoscope with LC followed by endoscopic retrograde cholangiopancreatography (ERC) and endoscopic sphincterotomy (ES) when indicated.

METHODS

We retrospectively reviewed the records of patients seen between 2004 and 2014 and treated with LC+LTCBDE or LC for gallstones and suspected choledocholithiasis. Postoperative complications and surgical outcomes were compared using t-test, Mann-Whitney U test, or chi-square test.

RESULTS

115 patients underwent successful LC+LTCBDE and 112 LC; follow-up data was available for 103 and 106 patients, respectively. Seventeen patients (16.5%) in the LC+LTCBDE group and 10 (28.6%) in the LC+ERC+ES group developed complications (P = 0.114). The LC+LTCBDE group had a significantly higher rate of satisfactory biliary function outcomes than the LC+ERC+ES group (98.1% vs. 85.7%, respectively) (P = 0.017).

CONCLUSIONS

Single-step LC+LTCBDE using an ultrathin choledochoscope may provide better outcomes in patients with gallstones and suspected choledocholithiasis.

Cholecystectomy After Endoscopic Sphincterotomy for Common Bile Duct Stones: Is Surgery Necessary?

It has been more than 30 years since the introduction of endoscopic sphincterotomy for the management of choledocholithiasis. Once introduced, this endoscopic intervention subsequently enabled clinicians to witness the natural history of leaving the gallbladder in situ once the common duct calculi were removed. Because many people were free of symptoms once the common bile duct was cleared of stones, patients and physicians alike soon questioned whether it was necessary to remove the gallbladder at all. Despite more than two decades of clinical research and numerous published reports, the answer to this question remains elusive. Similarly, the management algorithm for choledocholithiasis in patients with an intact gallbladder remains controversial. We review the available key data regarding this question. Importantly, there are only three prospective, randomized trials that have examined the need for cholecystectomy after endoscopic sphincterotomy, with case studies constituting most of the published reports. Consequently, the literature on this topic remains inconclusive, weakened by its retrospective approach, considerable variability between the patients studied, inconsistent inclusion and exclusion criteria, and frequently poor patient follow-up. Nonetheless, the preponderance of data favor removing the gallbladder after endoscopically clearing the common bile duct of gallstones because an estimated 25% of patients will experience recurrent symptoms within a 2-year follow up period. Recognizing the existence of various mitigating clinical factors, we advocate adopting a selective wait-and-see approach for high-risk patients, especially those with a life expectancy of less than 2 years or severely debilitating comorbidities.

Intraoperative ERCP for management of cholecystocholedocholithiasis

BACKGROUND

The introduction of minimally invasive techniques in management of biliary problems added new procedures for treating patients with cholecystocholedocholithiasis (CCL). This study presents the results of intraoperative ERCP (IOERCP) during LC as a single-session minimally invasive procedure for management of patients who have preoperatively diagnosed CBD stones.

METHODS

The database of patients presented to our center by CCL between October 2007 and December 2015 who were treated by LC and IOERCP was collected and analyzed. CBD stones were diagnosed using clinical data, laboratory tests and abdominal sonogram. MRCP was requested for doubtful cases. In the first cases ERCP was done using rendezvous technique, but in late cases standard ERCP immediately after completion of LC under the same anesthesia was used. Preoperative, intraoperative and postoperative data were recorded, analyzed and reported. Data reported include success/failure rate, complications, conversion to open surgery, operative details and incidence of residual CBD stones.

RESULTS

The study was conducted on 346 patients who had CCL. The mean age was 34.7 years, and 298 of them were females. The most common presentation was abdominal pain (98.5 %) and jaundice (64.9 %). Fifteen patients were excluded, and IOERCP was not done due to negative IOC results in 10 patients and conversion to open surgery in 5 patients. IOERCP was tried in the remaining 331 patients. The mean operative time was 55 min, and the mean hospital stay was 2.4 days. Major complications had been reported in 13/323 patients (4.0 %). Failure of CBD clearance was reported in 8 patients (2.4 %) with a success rate of 97.6 %. Thirty-day follow-up was possible in 142 patients, and there was a residual CBD stone in one patient and wound infection in another one.

CONCLUSIONS

IOERCP during LC is a safe and effective option for management of CCL.

Combination of laparoscopy and endoscopy for fusiform choledochal cysts

OBJECTIVE

The purpose of the study was to elucidate the efficacy of laparoscopy and endoscopy in the treatment of fusiform choledochal cysts (CDC).

MATERIALS AND METHODS

Between June 2006 and June 2012, 18 patients with fusiform CDC were treated in our hospital. All the 18 patients presented abdominal pain, and 13 presented jaundice. 18 patients presented elevated serum and urinary amylase, when abdominal pain appeared. All the patients underwent laparoscopic and endoscopic surgery successfully. The clinical presentation, radiological features and surgical treatment were analyzed. The postoperative symptoms, laboratory examination and bile duct changes were evaluated during follow-up term.

RESULTS

Intraoperative cholangiography showed filling defect, dilatation of the common channel and pancreatic ducts visualization in 18 patients, including 9 patients of pancreatic duct dilatation. The protein plugs and/or stones were removed completely under laparoscopy and endoscopy in 18 patients. Patients were followed-up for 3 months to 6 years. The biochemical and ultrasound examination showed no increase in pancreatic amylase and recurrence of the stones in the common channel and pancreatic duct.

CONCLUSIONS

The children with congenital fusiform biliary dilatation presented abdominal pain. Patients presented elevated serum and urinary amylase, when abdominal pain occurred. Filling defect and dilatation of the common channel showed by cholangiography. Laparoscopy and endoscopy clearance of the protein plugs and/or stones in the common channel in congenital fusiform biliary dilatation is effective, and the long-term result is good.

Acute Bacterial Cholangitis

Background

Acute bacterial cholangitis for the most part owing to common bile duct stones is common in gastroenterology practice and represents a potentially life-threatening condition often characterized by fever, abdominal pain, and jaundice (Charcot's triad) as well as confusion and septic shock (Reynolds' pentad).

Methods

This review is based on a systematic literature review in PubMed with the search items ‘cholangitis’, ‘choledocholithiasis’, ‘gallstone disease’, ‘biliary infection’, and ‘biliary sepsis’.

Results

Although most patients respond to empiric broad-spectrum antibiotic treatment, timely endoscopic biliary drainage depending on the severity of the disease is required to eliminate the underlying obstruction. Specific recommendations have been derived from the Tokyo guideline working group consensus 2006 and its update in 2013, albeit poorly evidence-based, providing a comprehensive overview of diagnosis, classification, risk stratification, and treatment algorithms in acute bacterial cholangitis.

Conclusion

Prompt clinical recognition and accurate diagnostic workup including adequate laboratory assessment and (aetiology-oriented) imaging are critical steps in the management of cholangitis. Treatment is directed at the two major interrelated pathophysiologic components, i.e. bacterial infection (immediate antimicrobial therapy) and bile duct obstruction (biliary drainage). As for the latter, transpapillary endoscopic drainage by stent or nasobiliary drain and/or same-session bile duct clearance, depending on individual disease severity, represent first-line treatment approaches.

Single-session minimally invasive management of common bile duct stones

Up to 18% of patients submitted to cholecystectomy had concomitant common bile duct stones. To avoid serious complications, these stones should be removed. There is no consensus about the ideal management strategy for such patients. Traditionally, open surgery was offered but with the advent of endoscopic retrograde cholangiopancreatography (ERCP) and laparoscopic cholecystectomy (LC) minimally invasive approach had nearly replaced laparotomy because of its well-known advantages. Minimally invasive approach could be done in either two-session (preoperative ERCP followed by LC or LC followed by postoperative ERCP) or single-session (laparoscopic common bile duct exploration or LC with intraoperative ERCP). Most recent studies have found that both options are equivalent regarding safety and efficacy but the single-session approach is associated with shorter hospital stay, fewer procedures per patient, and less cost. Consequently, single-session option should be offered to patients with cholecysto-choledocholithiaisis provided that local resources and expertise do exist. However, the management strategy should be tailored according to many variables, such as available resources, experience, patient characteristics, clinical presentations, and surgical pathology.

Comparative quality of life study between endoscopic sphincterotomy and surgical choledochotomy

AIM: To determine quality of life improvement in choledocholithiasis patients who underwent endoscopic sphincterotomy (EST) versus open choledochotomy (OCT).

METHODS: Eligible choledocholithiasis patients (n = 216) hospitalized in the Changhai Hospital between May 2010 and January 2011 were enrolled into a prospective study using cluster sampling. Patients underwent EST (n = 135) or OCT (n = 81) depending on the patient’s wishes. Patients were followed-up with a field survey and by correspondence. Patients were also given the self-administered Gastrointestinal Quality of Life Index (GIQLI) to measure patient quality of life before surgery, and at two and six weeks after the procedures.

RESULTS: With respect to baseline patient characteristics, the EST and OCT groups were comparable. After the procedure, gallstones were completely eliminated in all patients. Among 216 eligible patients, 191 patients (88.4%) completed all three surveys, including 118 patients who underwent EST (118/135; 87.4%) and 73 patients who underwent OCT (73/81; 90.1%). EST was associated with a significantly shorter hospital stay than OCT (8.8 ± 6.5 vs 13.9 ± 6.7 d; P < 0.001). The GIQLI score was similar between the EST and OCT groups before cholelithotomy (103.0 ± 15.4 vs 99.7 ± 10.2), but increased significantly in the EST group at two weeks (113.4 ± 12.0 vs 107.2 ± 11.2; P < 0.001) and six weeks (120.7 ± 10.6 vs 116.9 ± 7.5; P < 0.05) after the procedures.

CONCLUSION: EST, compared with OCT, is associated with better postoperative quality of life in patients treated for choledocholithiasis.

Long-term follow-up study of gallbladder in situ after endoscopic common duct stone removal in Korean patients

BACKGROUND

Although there has been much debate over the fate of the gallbladder (GB) after endoscopic common bile duct (CBD) stone removal, subsequent cholecystectomy is generally recommended in patients with GB stones to prevent further biliary complications. The aims of this study were to assess the natural course of the patients with GB in situ after endoscopic CBD stone removal and to evaluate the necessity of prophylactic cholecystectomy.

METHODS

Four hundred sixty-one patients who had undergone CBD stone removal at Yeungnam University Hospital between January 2000 and December 2004 were retrospectively analyzed, and 232 patients were ultimately enrolled in this study.

RESULTS

The mean duration of follow-up was 73 (range = 7-126) months in the cholecystectomy group and 66 (6-127) months in the GB in situ group (p = 0.168). Ten patients (14.7 %) in the cholecystectomy group and 31 patients (18.9 %) in the GB in situ group developed recurrent CBD stones (p = 0.295). The highest percentage of recurrent CBD stones in both groups was that for brown stones (80 and 80.6 %). In the GB in situ group, cumulative recurrence rates of CBD stones were not significantly different between patients with GB stones and without GB stones (15.9 vs. 20 %, p = 0.798). However, the incidence of acute cholecystitis was significantly higher in patients with GB stones compared to patients without GB stones (13.6 vs. 2.5 %, p = 0.003).

CONCLUSIONS

Prophylactic cholecystectomy seems to be unnecessary in patients without GB stones after endoscopic sphincterotomy. However, in patients with GB stones, elective cholecystectomy or close observation is recommended due to the higher risk of cholecystitis.

Minimally invasive phasic treatment protocol for the treatment of extrahepatic bile duct stones

OBJECTIVES

To identify the optimal treatment for extrahepatic bile duct stones using endoscopy, laparoscopy, and the combination of the two in different conditions and to develop phasic treatment protocols for their minimally invasive treatment.

PATIENTS AND METHODS

Of 2718 cases of extrahepatic bile duct stones collected from June 2005 to December 2011, 50 were randomly selected to receive open bile duct exploration and T-tube drainage, serving as the control group. For the rest, a one-scope protocol, two-scope protocol (two-scope protocol A or two-scope protocol B), or three-scope protocol was adopted according to the specific conditions of stones and the endoscopic treatment results. The treatment outcomes and postoperative clinical indicators of the minimally invasive treatment protocols were analyzed and compared with those of the control group.

RESULTS

Among the 2668 cases of extrahepatic bile duct stones receiving the phasic minimally invasive treatment, the treatment success rate was 97.79%, and there were no severe postoperative complications. Compared with the control group, the minimally invasive treatment protocols had higher success rates, less trauma, and significantly shortened hospital stays.

CONCLUSIONS

The protocols were applied step by step based on the different types and levels of extrahepatic bile duct stones, fully embodying the advantages of the combined minimally invasive treatment of endoscopy and laparoscopy, thus expanding the scope of minimally invasive surgical treatment for extrahepatic bile duct stones and improving treatment success rate.

Preoperative versus intraoperative endoscopic sphincterotomy for management of common bile duct stones

BACKGROUND

ERCP remains the prevailing method of treating CBDS; however, its ideal timing in respect to laparoscopic cholecystectomy (LC) is not defined. LC combined with intraoperative endoscopic sphincterotomy (IOES) was compared with preoperative endoscopic sphincterotomy (PES) followed by LC for management of preoperatively known cholecystocholedocholithiasis.

METHODS

Between June 2006 and September 2009, 198 patients diagnosed preoperatively by clinical assessment, liver chemistry, ultrasonography, and magnetic resonance cholangiopancreatography (MRCP) to have combined choledochocystolithiasis were eligible. They were randomly divided into two groups: PES/LC group (n = 100) and LC/IOES group (n = 98). The surgical times, surgical success rates, number of stone extractions, postoperative complications, retained common bile duct stones, and postoperative lengths of stay were compared prospectively.

RESULTS

There were no statistically significant differences in surgical time, surgical success rate, CBD diameter, stone size, or stone number between the two groups. The success rate was 95.3% and 97.8% for PES/LC and LC/IOES, respectively. There were no significant difference in postoperative retained stones, surgical time, and complications, but the total hospital stay was significantly shorter in the LC/IOES group.

CONCLUSIONS

PES/LC and LC/IOES are both good options for dealing with preoperatively diagnosed CBDS, but when there is enough experience and facilities, LC/IOES, as a single-stage treatment, would be preferable.

Relationship between periampullary diverticulum and recurrent bile duct stones after endoscopic surgery

AIM: To study the relationship between periampullary diverticulum and recurrent bile duct stones after endoscopic surgery.

METHODS: One hundred and eighty-five patients with periampullary diverticula were divided into two groups: 96 with peripapillary diverticula and 89 with direct opening of biliary duct into the diverticula. Ninety-five patients with non-diverticular disease were used as controls. After 8 years of follow-up, the recurrence rates of bile duct stones were compared among the three groups of patients.

RESULTS: The recurrence rates of bile duct stones at 8 years after endoscopic surgery were 26.32% in patients with periampullary diverticula, 34.83% in patients with direct opening of biliary duct into the diverticula, and 9.47% in controls. Significant differences were noted in the recurrence rates of bile duct stones between controls and the two groups of patients with periampullary diverticula (χ² = 8.78, 17.15, P < 0.05) though there was no statistical difference between the latter two groups (χ² = 1.71, P > 0.05).

CONCLUSION: Periampullary diverticula is closely related to the recurrence of bile duct stones after endoscopic surgery. There is no obvious relationship between the location of diverticula and the recurrence of bile duct stones. Periampullary diverticulum may be an important risk factor for recurrent bile duct stones.

Does endoscopic sphincterotomy reduce the recurrence rate of cholangitis in patients with cholangitis and suspected of a common bile duct stone not detected by ERCP?

BACKGROUND

It has not been established whether endoscopic sphincterotomy (ES) prevents subsequent cholangitis in patients with cholangitis and with a common bile duct (CBD) stone not documented by ERCP.

OBJECTIVE

The aim of this study was to investigate the role of ES on the recurrence of cholangitis in patients with a high probability of having a CBD stone, not demonstrated by ERCP.

DESIGN AND PATIENTS

A total of 117 patients who were diagnosed as having cholangitis and a high probability of a CBD stone, not detected by ERCP, were retrospectively reviewed. Cumulative recurrence rates of cholangitis were compared for treatments with and without ES.

SETTING

Multicenter, retrospective study.

INTERVENTIONS

ES.

MAIN OUTCOME MEASUREMENTS

Cumulative recurrence of cholangitis after ERCP.

RESULTS

Eighty-three patients underwent ES (ES group) and 34 patients did not (non-ES group). No statistically significant differences between the 2 groups were evident in terms of demographic factors or laboratory findings. The mean (standard deviation) follow-up was 22.1 +/- 17.2 months (range 3-66 months) in the ES group and 23.3 +/- 14.9 months (range 6-84 months) in the non-ES group (P = .72). The cumulative rates of cholangitis were 6.3% (4.8% vs 9.9%) at 1 year, 15.6% (9.2% vs 29.3%) at 3 years, and 19.5% (9.2% vs 52.9%) at 5 years for ES vs non-ES groups, respectively (P = .04). By multivariate analysis, ES reduced cholangitis recurrence, with a hazard ratio of 0.305 (95% CI 0.095-0.975, P = .045).

LIMITATIONS

Retrospective study.

CONCLUSIONS

ES reduced further episodes of cholangitis in patients with an episode of cholangitis and a high probability of choledocholithiasis, despite the lack of a CBD stone seen on ERCP.

Routine laparoscopic cholecystectomy after endoscopic sphincterotomy for choledocholithiasis in octogenarians: is it worth the risk?

BACKGROUND

No unanimous consensus has been reached as to the need for routine laparoscopic cholecystectomy (LC) after endoscopic sphincterotomy (ES) for choledocholithiasis in very elderly patients, who are considered as high-risk subjects for surgery.

METHODS

From 1991 through 1997, 170 patients were referred to undergo preoperative ES and routine LC for common bile duct (CBD) stones. The results for 27 patients (age 80 years or older) were compared with those achieved for younger patients. Successively, in a retrospective case-control study, the results for the selected patients were compared with those for 27 very elderly patients who underwent endoscopic retrograde cholangiopancreatography (ERCP), but did not receive LC. The mean follow-up period was 126 months.

RESULTS

Octogenarians showed longer surgery time (79 vs 51 min) and postoperative hospital stay (2.8 vs 1.2 days), as well as more early low-grade complications (15% vs 3%), whereas there were no differences in conversion rate or serious complications. Recurrent symptoms or complications developed in 48% of octogenarians not undergoing routine LC, and 30% finally needed surgery. One patient in the control group died after emergency cholecystectomy for acute cholecystitis. The results of surgery were significantly poorer for the control group.

CONCLUSIONS

Although a "wait-and-see" policy allowed two-thirds of LCs to be avoided in octogenarians, biliary-related events developed for every second patient, often requiring delayed surgery, with poorer results. Sequential treatment (ES followed by elective LC) is a safe procedure for octogenarians, and should be considered as a standard, definitive treatment for cholecystocholedocholithiasis even after the age of 80 years.

Endoscopic sphincterotomy with or without cholecystectomy for choledocholithiasis in high-risk surgical patients: a decision analysis

BACKGROUND

Laparoscopic cholecystectomy (LC) is recommended for patients with choledocholithiasis after ERCP with sphincterotomy (ES) and stone extraction.

AIM

We designed a decision model to address whether ES alone versus ES followed by LC (ES + LC) is the optimal treatment in high-risk patients with choledocholithiasis.

METHODS

Our cohort were patients with obstructive jaundice who have undergone an ES with biliary clearance. Recurrent biliary complications over a 2-year period stratified by gallbladder status (in/out) and age-stratified surgical complication rates were obtained from the literature. Failure of therapy was defined as either recurrent symptoms or death attributed to biliary complications.

RESULTS

For age 70-79 years, ES failed in 15% whereas ES + LC failed in 17% of cases. Mortality in the EC + LC group was 3.4 times that of the ES alone cohort. For age 80+ years, ES was dominant with an incremental success rate of 8%. Mortality in the ES + LC was 7.6 times that of ES. For age <70, ES + LC was the dominant strategy with an incremental success rate 5%. Sensitivity analysis in the groups confirmed our conclusions.

CONCLUSIONS

Management of choledocholithiasis by ES and stone clearance, but without cholecystectomy, should be considered for patients aged 70+. For low-risk patients, ES + LC should be performed to prevent recurrent biliary complications.

Identification of risk factors for stone recurrence after endoscopic treatment of bile duct stones

Recurrence of bile duct stones after endoscopic stone removal has been reported ranging from 4 to 24%. The risk of late complications such as stone recurrence is an important issue, especially for relatively young, otherwise healthy, patients with many years of future exposure time. The risk factors true recurrence of bile duct stones after endoscopic sphincterotomy (EST) and stone clearance are suboptimally defined. If patients at significant risk for stone recurrence could be identified, closer follow-up, earlier intervention, and possible preventive measures could theoretically decrease stone recurrence and late complications. The majority of patients with common bile duct stone who have EST and stone clearance will have no further biliary events during the remainder of their life. Whether identifying risk factors for recurrence can improve outcomes by prophylactic treatments or earlier interventions needs further prospective study.

Long-term prognosis after treatment of patients with choledocholithiasis

OBJECTIVE

This study was conducted to examine the long-term prognosis of after treatment of patients with choledocholithiasis, including the recurrence of lithiasis, and to thereby determine the best treatment modality for choledocholithiasis based on its pathological entity.

SUMMARY BACKGROUND DATA

Choledocholithiasis can be caused by either primary bile duct stones that originate in the bile duct or by secondary bile duct stones that have fallen out of the gallbladder. The recurrence rates vary depending on the type of choledocholithiasis.

METHODS

Two-hundred thirteen outpatients who were treated for choledocholithiasis from 1982 to 1996 were selected as subjects and monitored for a period ranging from 5 to 19 years (mean, 9.6 years). The 213 patients were divided into 3 groups: 87 patients who had undergone choledocholithotomy and T-tube drainage (including the use of the laparoscopic method), 44 patients who had undergone choledochoduodenostomy, and 82 patients whose stones were removed by endoscopic sphincterotomy (EST). Recurrence of lithiasis was examined for each type of treatment modality.

RESULTS

Choledochoduodenostomy was performed in 44 cases for the purpose of preventing any recurrence. The recurrent rate was analyzed in 169 cases. Choledocholithiasis recurred in 17 of the 169 cases (10.1%). The remaining 152 patients that showed no recurrence of lithiasis were examined and compared. The diameter of the common bile duct measured during the initial treatment was more dilated in patients with recurrent lithiasis (16.6 +/- 5.9 mm) than in patients without any recurrence (9.8 +/- 4.9 mm; P < 0.05). Peripapillary diverticula were observed in 10 of the 17 patients with recurrent lithiasis (58.8%), and in 34 of the 152 nonrecurrent patients (22.3%), showing that diverticula were more common in recurrent cases (P < 0.05). Furthermore, while primary bile duct stones were found in 11 of the 17 cases with recurrent lithiasis (64.7%), primary stones were found in only 37 of the 152 nonrecurrent patients (24.3%), showing primary bile duct stones were also more common in recurrent patients (P < 0.05). The recurrent patients were examined by surgical procedure. Nine patients with choledocholithotomy and T-tube drainage had a recurrence (10.3%), and 8 patients in the EST group had a recurrence (9.8%). The recurrence rates for these procedures were higher than for cases with choledochoduodenostomy (recurrence rate: 0%, P < 0.05). In particular, lithiasis recurred in 5 of the 12 patients with T-tube drainage for primary bile duct stones (41.7%).

CONCLUSION

Although choledocholithotomy and T-tube drainage, including open and laparoscopic surgery, is presently a common procedure for choledocholithiasis, this procedure will not necessarily prevent a recurrence of the disease. For older patients with primary bile duct stones, choledochoduodenostomy or EST is recommended.

New strategies for the treatment of gallstone disease

BACKGROUND

Symptomatic gallstones are generally accepted as being the indication for cholecystectomy. Generally, severe abdominal pain in epigastrium and in the right upper abdominal quadrant, and lasting for more than 15 min, is thought to be caused by gallstones. However, many patients with other abdominal complaints undergo cholecystectomy and are satisfied with the outcome of surgery. Possible ways to improve the results of cholecystectomy are discussed.

METHODS

Review of previous work by the authors.

RESULTS

The introduction of laparoscopic cholecystectomy has even led to an increase in cholecystectomies; in a higher complication rate; and in increased costs of the treatment of gallstone disease. Because of faster recovery, 70% of symptomatic gallstone patients are able and willing to undergo laparoscopic cholecystectomy in day care. Cholecystectomy after sphincterotomy and stone extraction in patients who have stones in the gallbladder was demonstrated to prevent gallstone-related symptoms in at least 40% of patients. If the gallbladder had to be removed later for symptomatic disease, however, this did not result in a higher rate of conversions and complications. Because of shortage in operation capacity in The Netherlands, there is a considerable delay between the diagnosis of symptomatic stones and cholecystectomy. Better selection of patients for cholecystectomy will not only improve the results of cholecystectomy, it will also reduce the number of cholecystectomies and patients on waiting lists. Delay of cholecystectomy is associated with more complications, longer operative times, higher conversion rates to open cholecystectomy and prolonged hospitalization. The efficacy of the bile salt ursodeoxycholic acid in preventing gallstone-related pain attacks and complications in patients with contraindications for operation or waiting to undergo cholecystectomy should be investigated further, since two retrospective studies have demonstrated favourable outcomes for this strategy.

CONCLUSION

The results of cholecystectomy are likely to be improved by better selection of patients, prevention of delay of the procedure and possibly treatment with ursodeoxycholic acid.
