Transcystic approach with micro-incision of the cystic duct and its confluence part in laparoscopic common bile duct exploration

Laparoscopic common bile duct exploration: what factors determine success?

BACKGROUNDS

Laparoscopic common bile duct exploration (LCBDE) has been shown to be effective in managing choledocholithiasis whilst avoiding ERCP-related complications. However, patient and technical factors effects outcome. This study aimed to explore the matters effecting the failure of LCBDE.

METHODS

All patients who underwent a laparoscopic cholecystectomy (LC) between 2007 and 2021 were identified using a prospective database. Data were collected for patients who underwent LCBDE including demographics, pre-operative investigations, intra-operative findings, technique of bile duct clearance and clearance rates, and post-operative outcomes. Predictors of failed LCBDE were identified.

RESULTS

Laparoscopic cholecystectomy was performed in 3648 patients. Of these, 374 underwent LCBDE for suspected choledocholithiasis. Choledochoscopy was most frequently used (58.8%) with a success rate of 84.1%. Small cystic duct diameter (4.7 vs. 3.4 mm, P = 0.002), stone size >6 mm (P = 0.02), stone: cystic duct ratio >1 (P = 0.04), and >3 stones was associated with failed LCBDE by univariate analysis. Small cystic duct diameter (OR: 0.45, 95% CI: 0.26-0.77, P = 0.004) and stone size >6 mm (OR: 0.23, 95% CI: 0.06-0.92), P = 0.04) correlated with failure by multivariate analysis. Failed LCBDE was associated with increased length of stay (6.6 days vs. 3.1 days, P = 0.001), however the rate of serious complications or mortality was unaffected.

CONCLUSION

LCBDE is safe and effective in managing choledocholithiasis. Factors such as cystic duct diameter, size and number of CBD stones, and stone: cystic duct ratio are associated with increased likelihood of inadequate clearance. The presence of these factors can help clinicians in decision making during LCBDE to improve chance of success.

Single-Stage Laparoscopic Common Bile Duct Exploration and Cholecystectomy Versus Two-Stage Endoscopic Stone Extraction Followed by Laparoscopic Cholecystectomy for Patients With Cholelithiasis and Choledocholithiasis: A Systematic Review

Gallbladder stones with common bile duct (CBD) stones can be managed by a single-stage laparoscopic approach with transcystic or transcholedochal CBD exploration and cholecystectomy or a two-stage approach with endoscopic retrograde cholangiopancreatography (ERCP) for stone extraction followed by laparoscopic cholecystectomy. Comparative outcomes between these approaches remain controversial. The objective was to compare single-stage laparoscopic CBD exploration and cholecystectomy versus two-stage ERCP stone removal followed by laparoscopic cholecystectomy for clearance of CBD stones, complications, length of stay, and costs. We systematically searched PubMed, EMBASE, and the Cochrane Central Register of Controlled Trials for randomized trials and observational studies comparing outcomes of interest between single and two-stage approaches. Meta-analyses using random effects models were conducted. Seven studies with 382 patients were included. The single-stage approach achieved higher stone clearance rates (OR: 1.53, 95% CI: 1.12-2.08) with a shorter length of stay (mean duration: 3.5 days, 95% CI: -5.1 to -1.9 days) compared to the two-stage method. No significant difference was seen in complication rates (45% vs 40%, p=0.43) or costs ($19,000 vs $18,000, p=0.34). For patients with gallbladder and CBD stones, single-stage laparoscopic CBD exploration with cholecystectomy appears superior for stone clearance while comparable in safety and cost to a two-stage approach. Further randomized trials are warranted.

Analysis of Laparoscopic Ultrathin Choledochoscope Curative Effect on Common Bile Duct Exploration and Choledocholithotomy in 47 Cases

Objective

The aim of the present study is to summarize the experience of using a 2. 7 mm choledochoscope for laparoscopic cholecystectomy combined with an ultrathin choledochoscope for common bile duct exploration and choledocholithotomy in the treatment of cholecystolithiasis associated with choledocholithiasis after the implementation of strict inclusion and exclusion criteria.

Methods

A retrospective analysis of 47 patients with cholecystolithiasis complicated with choledocholithiasis who were treated in the hepatopancreatobiliary surgery department of the Chinese People's Liberated Army General Hospital between January 2015 and December 2019 was performed in the present study. Clinical data of laparoscopic cholecystectomy combined with ultrathin choledochoscope transcystic duct exploration for common bile duct and choledocholithotomy.

Results

All 47 patients completed the operation successfully. The gallbladder duct was closed using a surgical clamp. Only 2 patients were administered with an abdominal drainage tube. The operation time was 50-160 min, the intraoperative blood loss was 5-50 ml, and the postoperative hospital stay was 2-8 days. No patients had serious complications, such as bile leakage, postoperative bleeding, cholangitis, biliary pancreatitis, and wound infection. Minor complications, such as abdominal pain (Abdominal pain was defined as a patient felt tolerable or unbearable abdominal pain but improved or disappeared with medication) and diarrhea, were present in a few patients; these improved after conservative treatment. There was no recurrence of calculi during the 1-5 years of follow-up, and the patient quality of life was good.

Conclusion

Laparoscopic cholecystectomy combined with ultrathin choledochoscope common bile duct exploration and choledocholithotomy is a safe and effective method after adopting strict inclusion and exclusion criteria. This technology was started in the First Medical Center, Chinese People's Liberation Army General Hospital in September 2009, and it has become extremely mature in the past 5 years.

Lessons learnt from the first 200 unselected consecutive cases of laparoscopic exploration of common bile duct stones at a district general hospital

BACKGROUND

The management of choledocholithiasis evolves with diagnostic imaging and therapeutic technology, facilitating a laparoscopic approach. We review our first 200 cases of laparoscopic exploration of the common bile duct, highlighting challenges and lessons learnt.

METHODS

We retrospectively studied the first 200 cases of laparoscopic cholecystectomy with common bile duct exploration between 2006 and 2019. The database contains demographics, clinicopathological characteristics, diagnostic modalities, operative techniques, duration and outcomes.

RESULTS

We compared two approaches: transcystic vs. transcholedochal in our 200 cases. Choledocholithiasis was suspected preoperatively in 163 patients. 21 cases found no stones. Of the remainder, 111/179 cases were completed via the transcystic route and the remaining were completed transcholedochally (68/179); 25% of the transcholedochal cases were converted from a transcystic approach. CBD diameter for transcystic route was 8.2 vs. 11.0 mm for transcholedochal. Total clearance rate was 84%. Retained or recurrent stones were noted in 7 patients. Length of stay was 5.8 days, 3.5 days in the transcystic route vs. 9.4 days after transcholedochal clearance. Eight patients required re-operation for bleeding or bile leak. No mortalities were recorded in this cohort, but 2 cases (1%) developed a subsequent CBD stricture.

CONCLUSION

Concomitant laparoscopic common bile duct clearance with cholecystectomy is feasible, safe and effective in a district general hospital, despite constraints of time and resources. The transcystic route has a lower complication rate and shorter hospital stay, and hence our preference of this route for all cases. Advancements in stone management technology will allow wider adoption of this technique, benefitting more patients.

Laparoscopic Exploration of the Common Bile Duct: A Systematic Review of the Published Evidence Over the Last 10 Years

INTRODUCTION

Endoscopic and open surgical interventions are widely implemented as the standard practice in common bile duct exploration. However, the laparoscopic approach has been also reported to have comparative/superior outcomes in this concept. This has created an ongoing debate about the ideal approach to adopt in practice.

METHODS

A systematic review of the published evidence over the last decade that has looked into the outcomes of laparoscopic exploration of the common bile duct through transductal and transcystic approaches.

RESULTS

Our systematic review included 36 relevant papers. The majority were based on nonrandomized protocols conducted in single centers with high expertise. The data analysis showed that laparoscopic common bile duct exploration through both approaches was successful in more than 84% of the patients, with an average length of hospital stay of 5.6 days. Conversion to open surgery was reported in 5%-8% of the patients, and the bile leak rates from the more recent studies was 0%-12%, with mortality figures of 0%-1.3%. The outcomes were statistically in favor of the transcystic route when compared to the transductal route from the viewpoints of bile leak rates, mean operative time, duration of hospital stay and morbidity.

CONCLUSION

In experienced hands, both laparoscopic approaches in common bile duct exploration are safe in patients who are clinically fit to have this intervention. It is associated with a statistically significant lower overall morbidity and shorter duration of hospital stay when compared to open surgery. Relevant up-to-date high-quality randomized trials are unavailable.

Dilation of the cystic duct confluence in laparoscopic common bile duct exploration and stone extraction in patients with secondary choledocholithiasis

Background

Many options exist for the management of cholelithiasis and secondary choledocholithiasis. Among them, laparoscopic common bile duct exploration (LCBDE) with choledocotomy followed by laparoscopic cholecystectomy has gained popularity. However, efforts should be made to ensure minimally invasive or noninvasive management of the common bile duct (CBD). The purpose of this study was to explore the clinical experience of non-invasive surgical modality, i.e., laparoscopic transcystic dilation of the cystic duct confluence in CBD exploration (LTD-CBDE), including feasibility, safety, adverse events, and incidence.

Methods

In this retrospective analysis, 68 patients were offered the LTD-CBDE technique from December 2015 to April 2018 based on patient’s own intention. During the surgery, the cystic duct confluence was dilated with separation forceps and/or a columnar dilation balloon. Subsequently, CBD exploration and stone extraction were performed with a choledochoscope. The entrance of the CBD was covered with a cystic duct stump wall and was subjected to primary closure at the end of surgery.

Results

Forty-nine females and 19 males with cholelithiasis and secondary choledocholithiasis were included. The mean age was 53 years old (18 to 72 year). Of these patients, 62 (91.2%) were successfully treated with the LTD-CBDE technique, and bile leakage was observed in 3 patients (4.4%). The mean operation time was 106 min, and the mean hospital stay was 5.9 days. Among the other 6 patients, 3 were converted to open cholecystectomy due to severe fibrosis, unclear anatomical structure at Calot’s triangle (n = 2) or Mirizze syndrome (n = 1); LCBDE was performed in 3 patients due to cystic duct atresia (n = 2) and low level of flow from the gallbladder duct into the CBD (n = 1). These patients had a smooth postoperative course. In total, 43/68 of the patients presented no radiological evidence of retained CBD stones at the postoperative follow-up (40 patients treated with LTD-CBDE) 1 year later.

Conclusions

The current work suggests that LTD-CBDE for the management of cholelithiasis and secondary choledocholithiasis is a feasible, safe and effective technique with a low complication rate. LTD-CBDE offers another alternative for surgeons to treat patients in similar scenarios. However, additional randomized, controlled studies are needed to demonstrate its efficacy, safety, and impact on CBD stenosis.

Management of bile duct stones at cholecystectomy: an Australian single-centre experience over 2 years

BACKGROUND

Bile duct stones with an intact gallbladder can be treated with either bile duct exploration at cholecystectomy or endoscopic retrograde cholangiopancreatography (ERCP) before or after cholecystectomy. The aim of this study was to evaluate the management of bile duct stones at cholecystectomy at our institution. We also aimed to identify risk factors for failure of ductal clearance in our series.

METHODS

A retrospective review of 690 laparoscopic cholecystectomies over a 2-year period was performed. Patients who underwent laparoscopic bile duct exploration formed the study population.

RESULTS

Of 69 patients with suspected bile duct stones at cholecystectomy 67 (97%) patients underwent laparoscopic bile duct exploration upfront. Complete ductal clearance was achieved in 52 (78%) patients. Postoperative complications (10/67, 15%) included postoperative bleeding (2/67, 3%), bile leak (1/67, 1%), and superficial wound infection (1/67, 1%). There was no mortality. The mean operative time was 126 min and the median length of stay was 2 (1-4) days. A wider common bile duct (CBD) (≥ 8 mm) increased the risk of failed ductal clearance (OR 4.50; 95% confidence interval (CI) 1.15-19.23).

CONCLUSION

This study found that laparoscopic bile duct exploration can effectively and safely treat bile duct stones suspected at cholecystectomy.

Protocol for the CREST Choles (Chinese REgistry Study on Treatment of Cholecysto-Choledocholithiasis) study: an ambispective, multicenter, observational, open-cohort study

INTRODUCTION

The best approach for choledocholithiasis remains a matter of debate. Choledocholithiasis is usually treated with endoscopic sphincterotomy (EST), laparoscopic common bile duct exploration (LCBDE) or laparoscopic transcystic common bile duct exploration (LTCBDE). Data pertaining to the clinical outcomes of these approaches in the management of patients with cholecysto-choledocholithiasis in China are limited. An analysis of the economic burden associated with these treatments is lacking. The Chinese REgistry Study on the Treatment of Cholecysto-Choledocholithiasis (CREST Choles) was designed to address these issues in a real-world setting.

METHODS AND ANALYSIS

CREST Choles was an ambispective, multicenter, observational, open-cohort study. A total of 2700 patients undergoing one of the three treatments (EST+laparoscopic cholecystectomy (LC), LCBDE+LC and LTCBDE+LC) during the period from 1 January 2013 to 1 December 2018 at participating centres were enrolled in the study. Patients with gallstones and confirmed common bile duct stones were included. Data pertaining to demographics, disease history, procedural details, imaging features and follow-up were collected. Follow-up was conducted at least 6 months after enrolment in the study and annual follow-up will be conducted until December 2020. The primary outcome is the rate of adverse outcomes within 3 years postoperatively. Economic analysis (eg, incremental cost-effectiveness ratio) would be performed to compare expense across treatments.

ETHICS AND DISSEMINATION

Ethical approval was obtained at all participating centres. The registry presented is the first attempt to comprehensively evaluate the cost of treatment for cholecysto-choledocholithiasis in China. Findings are expected to be available in 2020 and will facilitate clinical decision making in such cases.

Laparoscopic Transcystic Versus Transductal Common Bile Duct Exploration: A Systematic Review and Meta-analysis

OBJECTIVE

To evaluate comparative outcomes of laparoscopic transcystic (TC) and transductal (TD) common bile duct (CBD) exploration.

METHODS

We systematically searched MEDLINE, EMBASE, CINAHL, CENTRAL, the World Health Organization International Clinical Trials Registry, ClinicalTrials.gov, ISRCTN Register, and bibliographic reference lists. CBD clearance rate, perioperative complications, and biliary complications were defined as the primary outcome parameters. Procedure time, length of hospital stay, conversion to open procedure were the secondary outcomes. Combined overall effect sizes were calculated using random-effects models.

RESULTS

We identified 30 studies reporting a total of 4073 patients comparing outcomes of laparoscopic TC (n = 2176) and TD (N = 1897) CBD exploration. The TC approach was associated with significantly lower overall complications (RD: -0.07, P = 0.001), biliary complications (RD: -0.05, P = 0.0003), and blood loss (MD: -16.20, P = 0.02) compared to TD approach. Moreover, the TC approach significantly reduced the length of hospital stay (MD: -2.62, P < 0.00001) and procedure time (MD: -12.73, P = 0.005). However, there was no significant difference in rate of CBD clearance (RD: 0.00, P = 0.77) and conversion to open procedure (RD: 0.00, P = 0.86) between two groups.

CONCLUSIONS

Laparoscopic TC CBD exploration is safe and reduces overall morbidity and biliary complications compared to the TD approach. Moreover, it is associated with significantly shorter length of hospital stay and procedure time. High-quality randomised trials may provide stronger evidence with respect to impact of the cystic duct/CBD diameter, number or size of CBD stones, or cystic duct anatomy on the comparative outcomes of TC and TD approaches.

Five-year follow-up outcomes of laparoscopic choledochoscopy via the cystic duct for choledocholithiasis in patients with gallstones and common bile duct stones

BACKGROUND

There are many treatments for gallstones combined with common bile duct stones. Currently, laparoscopic cholecystectomy plus common bile duct exploration and endoscopic sphincterotomy plus laparoscopic cholecystectomy are often used, but T tube drainage is required for the former, and the latter is controversial due to the destruction of the Oddi sphincter.

AIM

To investigate the clinical effect of laparoscopic choledochoscopy in the treatment of gallstones with common bile duct stones.

METHODS

A total of 125 patients who underwent laparoscopic choledochoscopy and cholecystectomy for gallbladder stones and common bile duct stones were followed for 5 years from January to December 2013. The clinical effects were analyzed.

RESULTS

The operation was successful in 122 cases, with a success rate of 97.6%. The average age of the patients was 58.21 ± 13.01 years old. The mean operation time was 87.95 ± 39.12 min, and mean intraoperative blood loss was 11.27 ± 6.85 mL. All patients underwent balloon dilatation, of whom 33 underwent microctomy at the confluence of the cystic duct and 5 underwent lithotrity via choledochoscopy. The mean time to first postoperative exhaust was 32.48 ± 17.85 h, and mean postoperative hospital stay was 2.03 ± 1.62 d. The rate of complications at short-term follow-up was 5.74%, and there were a total of 7 cases, including 4 cases of postoperative pancreatitis cured by symptomatic treatment with octreotide and ulinastatin, 2 cases of bile leakage cured by ENBD drainage, and 1 case of surgical wound infection cured by re-dresses. The rate of complications at 5-year follow-up was 4.92%, and there were 4 cases of recurrent common bile duct stones, including 1 case with intrahepatic bile duct stones and 2 cases with pancreatitis. Four patients died, of whom two patients had a myocardial infarction, one had a lung infection, and one had a car accident, all of which were not related to the operation.

CONCLUSION

Laparoscopic choledochoscopy for the treatment of gallbladder stones combined with common bile duct stones has both good short- and long-term results, with the advantages of little trauma, rapid recovery, and few complications.

Laparoscopic transcystic common bile duct exploration: surgical indications and procedure strategies

BACKGROUND

LTCBDE combined with or without modified techniques is safe and efficacious for the management of gallstones and concomitant, even large, common bile duct (CBD) stones.

METHODS

To describe the surgical indications and procedure strategies of laparoscopic transcystic common bile duct exploration (LTCBDE), a retrospective analysis of 205 patients with concomitant gallstones and CBD stones treated using LTCBDE between June 2008 and June 2015 was performed. Clinical data on disease characteristics, methods for cystic duct incision and CBD stone extraction (with or without laser lithotripsy), and surgical outcomes were collected and reviewed.

RESULTS

CBD stones were successfully cleared in all patients. No patient was converted to choledochotomy or laparotomy. The cystic duct diameter ranged 3-8 mm, and 85 patients with cystic duct diameter ≥ 5 mm. The mean time for CBD stone extraction was 25.3 min, with the operative time ranged from 63 to 170 min. Lithotripsy was used in 74 (36.1%) patients among which 26 patients with cystic duct diameter ≥ 5 mm. Estimated blood loss during surgery was 10-120 ml per patient, and no intra-operative blood transfusions were needed. The mean postoperative hospital stay was 5.1 (range 3-7) days, and postoperative complications developed in seven patients. No bile duct injury, stricture, remnant, recurrent stones, or other adverse events were observed during the mean follow-up of 8 months.

CONCLUSIONS

Based on preoperative MRCP and intra-operative IOC findings about cystic duct diameter, the diameter of CBD, CBD stone size, we summarized and proposed the surgical indications and suitable techniques and strategies during LTCBDE.

Transcystic versus traditional laparoscopic common bile duct exploration: its advantages and a meta-analysis

BACKGROUND

The best approach for treating common bile duct stones remains a matter of debate. Traditional laparoscopic common bile duct exploration (LCBDE) can cause adverse events such as stenosis of the bile duct. Moreover, with advances in technology and surgical skills, the use of laparoscopic transcystic common bile duct exploration (LTCBDE) is gradually rising.

OBJECTIVES

To compare the safety, feasibility, and short-term clinical benefits of LTCBDE and LCBDE through matched cases.

METHODS

Web of science, Cochrane, PubMed, and CNKI were searched systematically to identify studies published between January 2007 and December 2017 that compared LTCBDE and LCBDE without a restriction of languages. This meta-analysis was performed using Review Manager 5.3.

RESULTS

Twenty-one studies matched the selection criteria, including 1561 cases of LTCBDE and 1500 cases of LCBDE. There was no obvious difference in stone clearance (OR 1.44, 95% CI 0.84-2.47; P = 0.18). However, LTCBDE had a shorter operative time (MD - 17.72, 95% CI - 19.42 to - 16.02; P < 0.00001) and shorter hospital stay (MD - 2.20, 95% CI - 2.32 to - 2.08; P < 0.00001). Besides, the LTCBDE group showed significantly better results for blood loss (MD - 7.61, 95% CI - 8.85 to - 6.37; P < 0.00001) and postoperative complications (OR 0.28, 95% CI 0.19-0.41; P < 0.00001). In addition, LTCBDE was more cost efficient (MD - 2.51, 95% CI - 2.72 to - 2.30; P < 0.00001). Further, we calculated the absolute mean of operative time (LTCBDE:LCBDE = 97.56:117.81 min), hospital stay (LTCBDE:LCBDE = 5.22:8.91 days), hospital expenses (LTCBDE:LCBDE = 8646.121:11848.31 RMB), blood loss (LTCBDE:LCBDE = 29.3:52.0 ml), the rate of CBD stone clearance (LTCBDE:LCBDE = 92.8:95.0%), and postoperative complications (LTCBDE:LCBDE = 6.7:14.6%) in both groups to obtain more convincing results.

CONCLUSIONS

The stone clearance of LTCBDE was equal to that of LCBDE, and LTCBDE demonstrated a shorter operative time, lower blood loss, and other advantages. Thus, the surgical procedure of laparoscopic transcystic choledochotomy is feasible and safe.

Various approaches of laparoscopic common bile duct exploration plus primary duct closure for choledocholithiasis: A systematic review and meta-analysis

BACKGROUND

Common bile duct (CBD) stones may occur in up to 3%-14.7% of all patients with cholecystectomy. Various approaches of laparoscopic CBD exploration plus primary duct closure (PDC) are the most commonly used and the best methods to treat CBD stone. This systematic review was to compare the effectiveness and safety of the various approaches of laparoscopic CBD exploration plus PDC for choledocholithiasis.

DATA SOURCES

Randomized controlled trials (RCTs) and non-randomized controlled trials (NRCTs) (case-control studies or cohort studies) were searched from Cochrane library (until Issue 2, 2015), Web of Science (1980-January 2016), PubMed (1966-January 2016), and Baidu search engine. After independent quality assessment and data extraction, meta-analysis was conducted using RevMan 5.1 software.

RESULTS

Four RCTs and 18 NRCTs were included. When compared with choledochotomy exploration (CE) plus T-tube drainage (TTD) (CE + TTD), CE plus PDC (CE + PDC) and CE + PDC with biliary drainage (BD) (CE + PDC + BD) had a lower rate of postoperative biliary peritonitis (OR = 0.22; 95% CI: 0.06, 0.88; P < 0.05; OR = 0.27; 95% CI: 0.08, 0.84; P < 0.05; respectively) where T-tubes were removed more than 3 weeks. The operative time of CE + PDC was significantly shorter (WMD = -24.82; 95% CI: -27.48, -22.16; P < 0.01) than that of CE + TTD in RCTs. Cystic duct exploration (CDE) plus PDC (CDE + PDC) has a lower rate of postoperative complications (OR = 0.39; 95% CI: 0.23, 0.67; P < 0.01) when compared with CE + PDC. Confluence part micro-incision exploration (CME) plus PDC (CME + PDC) has a lower rate of postoperative bile leakage (OR = 0.17; 95% CI: 0.04, 0.74; P < 0.05) when compared with CE + PDC.

CONCLUSION

PDC with other various approaches are better than TTD in the treatment of choledocholithiasis.

Laparoscopic Exploration Can Salvage Recurrent Common Bile Duct Stone after Cholecystectomy

Conventionally, patients suffered from recurrent common bile duct (CBD) stone after cholecystectomy are suggested to be treated with endoscopic retrograde cholangiopancreaticography. This study was designed to explore the feasibility of laparoscopic common bile duct exploration (LCBDE) as a salvage procedure for recurrent CBD calculi after cholecystectomy. A retrospective review was conducted of data from 65 patients who underwent LCBDE for recurrent CBD calculi after cholecystectomy from January 2011 to July 2015. LCBDE was successfully carried out in 61 cases, with a successful rate of 93.8 per cent. Three cases required open conversion because of serious abdominal adhesion, and one case for intraoperative bleeding. Postoperative bile leakage occurred in two cases, and bile peritonitis developed in one case; all these three patients with complications were fully cured by conservative treatment. A postoperative retained CBD stone was found in one patient, which was extracted with endoscopic sphincterotomy. Furthermore, it was found that the mean operative time and length of postoperative hospital stay were much shorter in primary closure group (n = 49) than in T-tube drainage group (n = 12), and the hospital expense was also lower in primary closure group. We suggest that LCBDE could be a novel approach as a salvage procedure for the recurrent CBD stone after cholecystectomy, and we prefer to intraoperative primary closure of CBD if possible.

Three modalities on management of choledocholithiasis: A prospective cohort study

BACKGROUND

Choledocholithiasis can be managed by endoscopic retrograde cholangiopancreaticography/endoscopic sphincterotomy (ERCP/EST) or laparoscopic common bile duct (CBD) exploration by transcystic (TC) or transductal (TD) stone extraction.

OBJECTIVE

The aim of this study was to evaluate the safety and effectiveness of common bile duct stones extraction by ERCP/EST, TC approach and TD approach for choledocholithiasis, with specific emphasis on ERCP/EST, TC approach versus TD approach.

METHODS

Between January 2011 and June 2014, a total of 161 patients were scheduled for two-stage (preoperative ERCP/EST followed by cholecystectomy, ERCP group, n = 52)or single-stage (laparoscopic exploration of the CBD combined with cholecystectomy, n = 109) treatment for choledocholithiasis with concomitant cholecystitis. Laparoscopic common bile duct exploration was performed by TC approach (TC group, n = 63)or TD approach (TD group, n = 46). T-tube insertion was performed in selected patients. Patients were regularly followed up at bimonthly intervals or more frequently in presence of any symptom. Primary outcomes measures included length of hospital stay, successful bile duct clearance, postoperative/procedural morbidity and mortality.

RESULTS

Successful bile duct clearance was 100.0% in TD group, 93.7% in TC group and 92.3% in ERCP group. 4 cases in the TC group and 4 cases in the ERCP group required an extra choledocholithotomy due to impacted stones. 9 patients underwent T-tube drainage in TD group comparing to 1 case in ERCP group and no cases in TC group. Comparing to TC group, there was more postoperative morbidity in TD and ERCP group. Bile leaks were more frequent in TD group (8.7%) than TC (3.2%) and ERCP group (3.8%), which prolonged hospitalization in TD group than TC and ERCP group. 2 patients in ERCP group suffered duodenal perforation and one of them died because of the complication. However, total procedural morbidity was 0% in TC and TD group.

CONCLUSION

TD stone extraction has a higher stone clearance but with a higher risk of bile leaks. Procedural morbidity is more often happened in ERCP/EST, which may result in serious consequences. TC stone extraction, which seems an effective approach with lower complication rates, is accessible techniques simplifying the operation procedure by avoiding choledocholithotomy and subsequent T-tube insertion.

Five hundred consecutive laparoscopic common bile duct explorations: 5-year experience at a single institution

BACKGROUND

Laparoscopic common bile duct exploration (LCBDE) has gained wide popularity in the treatment of choledocholithiasis. Bile leakage remains a major cause of postoperative morbidity. The aim of this study was to report 5-year results of 500 LCBDEs and identify risk factors associated with bile leakage.

METHODS

Five hundred consecutive LCBDEs performed in one institution from September 2011 to June 2016 were reviewed. Patients' clinical data were retrospectively collected and analyzed. Univariable and multivariable analysis of bile leakage was performed by logistic regression.

RESULTS

We found stones (n = 388) or bile sludge (n = 71) in 459 patients (92%) on exploration, leaving 41 patients (8%) without stones. Operative time was 128 min in the first 250 LCBDEs, and this decreased to 103 min in the second 250 LCBDEs (P = 0.0004). Four hundred and eight (82%) procedures were completed with primary closure after choledochotomy; the rate of primary closure increased significantly in the second 250 patients compared with the first (88 vs 76%; P = 0.0005), whereas T-tube placement (2 vs 6%; P = 0.0225) and transcystic approach (7 vs 12%; P = 0.0464) decreased, respectively. Stone clearance was successful in 495 patients (99%). Overall morbidity was 5%, and bile leakage occurred in 17 patients (3.4%). Two patients died from bile leakage. The median follow-up was 24 months with stone recurrence occurred in two patients and bile duct stricture in one patient. Univariable analysis identified diameter of the common bile duct (CBD), stone clearance, and T-tube insertion as risk factors related to bile leakage. Multivariable analysis taking these three factors into account identified non-dilated CBD (risk ratio (RR) = 9.87; P = 0.007) and failure in stone clearance (RR = 11.88; P = 0.024) as significant risk factors.

CONCLUSIONS

Bile leakage following LCBDE is associated with diameter of the CBD and stone clearance. LCBDE would be safer in proficient laparoscopic surgeons with a careful selection of patients.

Micro-Incision of the Cystic Duct Confluence in Laparoscopic Common Bile Duct Exploration for Elderly Patients with Choledocholithiasis

Common bile duct (CBD) stones are common in elderly patients. The laparoscopic transcystic approach with micro-incision of the cystic duct confluence in common bile duct exploration (LTM-CBDE) is a modified laparoscopic transcystic approach. Its safety and efficacy have not been studied in elderly patients with secondary choledocholithiasis. This study evaluates the safety and efficacy of LTM-CBDE in elderly (≥65 years) patients with secondary choledocholithiasis and compares the results with those in younger patients. In this retrospective analysis, 128 patients underwent LTM-CBDE from March 2007 to December 2013. The patients were divided into two groups according to age: the elderly group consisted of 50 patients aged ≥65 years and the younger group consisted of 78 patients aged <65 years. The preoperative morbidity rate, American Society of Anesthesiologists (ASA) score, previous abdominal operations, operation time, postoperative hospital stay, open conversion rate, postoperative complication rate, residual stone rate, recurrence rate and mortality were compared in both groups. The preoperative morbidity (41 vs. 28) and ASA score (2.5 ± 0.7 vs. 1.8 ± 0.6) were higher in the elderly group (P = 0.000, in both groups). No significant differences in previous abdominal operations, operation time, postoperative hospital stay, open conversion rate, postoperative complication rate, residual stone rate, recurrence rate and mortality (P > 0.05) were found between the two groups from March 2007 to December 2013. LTM-CBDE is a safe and effective treatment procedure for elderly patients with secondary choledocholithiasis. For suitable patients, we recommend LTM-CBDE as the treatment of choice.

Laparoscopic Transcystic Common Bile Duct Exploration in the Elderly is as Effective and Safe as in Younger Patients

BACKGROUND

Choledocholithiasis represents a greater proportion of gallstone in the elderly. Elderly patients have more comorbidity, which could increase the operative risk and postoperative complications. However, no study has focused on the effect and safety of laparoscopic transcystic common bile duct exploration (LTCBDE) in elderly patients. The aim of this study was to investigate whether LTCBDE can be performed effectively and safely in elderly patients.

METHODS

This is a retrospective study of patients who underwent LTCBDE for choledocholithiasis performed from January 2010 to December 2012. Patients of age 70 or older were included in the elderly group. The rest integrated the younger group. Demographic data and perioperative parameters were compared between groups.

RESULTS

From January 2010 to December 2012, 171 patients admitted for choledocholithiasis and gallstone attempted a single-step treatment combining LTCBDE and laparoscopic cholecystectomy. There were 104 women (60.8%) and 67 men (39.2%) with a median age of 57 (range 24-87) years. Elderly patients had significantly more preoperative risk factors. However, there was no significant difference in the success rate of LTCBDE (96.9% versus 92.7%, P = .142) for the two groups. The operative time was a little longer in elderly group than in younger group: median 80 (60-110) minutes versus 70 (50-95) minutes, respectively (P < .001). Postoperative recovery was slower in elderly group than in younger group, as reflected by a longer median postoperative hospital stay (2 days versus 1 day, P < .001) and a higher rate of abdominal drain placed (17.1% versus 8.5%, P = .202). The rates of postoperative complications at discharge were similar between groups (3.0% versus 4.9%, P = .952).

CONCLUSION

LTCBDE in the elderly patients is as effective and safe as in younger patients.

Laparoscopic Transcystic Common Bile Duct Exploration: Advantages over Laparoscopic Choledochotomy

Purpose

The ideal treatment for choledocholithiasis should be simple, readily available, reliable, minimally invasive and cost-effective for patients. We performed this study to compare the benefits and drawbacks of different laparoscopic approaches (transcystic and choledochotomy) for removal of common bile duct stones.

Methods

A systematic search was implemented for relevant literature using Cochrane, PubMed, Ovid Medline, EMBASE and Wanfang databases. Both the fixed-effects and random-effects models were used to calculate the odds ratio (OR) or the mean difference (MD) with 95% confidence interval (CI) for this study.

Results

The meta-analysis included 18 trials involving 2,782 patients. There were no statistically significant differences between laparoscopic choledochotomy for common bile duct exploration (LCCBDE) (n = 1,222) and laparoscopic transcystic common bile duct exploration (LTCBDE) (n = 1,560) regarding stone clearance (OR 0.73, 95% CI 0.50–1.07; P = 0.11), conversion to other procedures (OR 0.62, 95% CI 0.21–1.79; P = 0.38), total morbidity (OR 1.65, 95% CI 0.92–2.96; P = 0.09), operative time (MD 12.34, 95% CI −0.10–24.78; P = 0.05), and blood loss (MD 1.95, 95% CI −9.56–13.46; P = 0.74). However, the LTCBDE group showed significantly better results for biliary morbidity (OR 4.25, 95% CI 2.30–7.85; P<0.001), hospital stay (MD 2.52, 95% CI 1.29–3.75; P<0.001), and hospital expenses (MD 0.30, 95% CI 0.23–0.37; P<0.001) than the LCCBDE group.

Conclusions

LTCBDE is safer than LCCBDE, and is the ideal treatment for common bile duct stones.

Laparoscopic common bile duct exploration: choledochotomy versus transcystic approach?

PURPOSE

To compare the difference of primary suture following 3-port laparoscopic common bile duct exploration (LCBDE) between modified transcystic and transcholedochal approach in the treatment of choledocholithiasis.

MATERIALS AND METHODS

Patients who underwent 3-port LCBDE by modified transcystic approach (n = 80) and those who underwent 3-port LCBDE by transcholedochal approach (n = 209) were included in this study. The operative time, duration of hospital stay, diameter of the cystic duct, diameter of the common bile duct (CBD), complications, and demographics were retrospectively analyzed in all patients.

RESULTS

All operations were successfully performed. No patient was converted to laparotomy. No mortality was associated with the 2 groups. There was no significant difference between the 2 groups for the operative time (91.94 ± 34.21 min vs. 96.13 ± 32.15 min), duration of hospital stay (9.82 ± 3.48 d vs. 10.74 ± 5.34 d), diameter of cystic duct (0.47 ± 0.09 cm vs. 0.47 ± 0.08 cm), and complications (2.5% vs. 2.87%) (all P > 0.05). A significant difference was observed in terms of the diameter of CBD (1.18 ± 0.29 cm vs. 1.04 ± 0.24 cm P < 0.05).

CONCLUSIONS

The modified transcystic LCBDE was safe and feasible for treating choledocholithiasis but it might be more suitable for the CBD with a smaller diameter.

Learning curve and outcome of laparoscopic transcystic common bile duct exploration for choledocholithiasis

BACKGROUND

The best approach for cholecystocholedocholithiasis remains a matter of debate. The aim of this study was to evaluate the technical aspects, learning curve and outcome of laparoscopic transcystic common bile duct exploration (LTCBDE).

METHODS

Patients who underwent laparoscopic cholecystectomy with LTCBDE between January 2007 and December 2012 were identified from an institutional database. Data on preoperative investigations, intraoperative and postoperative findings were retrieved retrospectively from the patients' hospital notes.

RESULTS

There were 399 women (56·4 per cent) and 309 men (43·6 per cent), with a median age of 58 (range 18-87) years. Microincision (incision of the cystic duct at the confluence with the common bile duct (CBD) with extension of only 3-5 mm at the lateral margin of the CBD) and lithotripsy were used in the transcystic exploration in 119 patients, and increased the success rate of LTCBDE from 74·2 to 91·0 per cent. The median duration of operation was 85 (i.q.r. 65-120) min and the median postoperative hospital stay was 2 (1-3) days. Retained common bile duct stones were observed in 13 patients, and postoperative complications developed in 27 patients. The cumulative sum duration of operation learning curve comprised two phases; phase 1 included the first 250 patients and phase 2 the remaining 458 patients. Duration of operation and postoperative hospital stay decreased with increasing volume per surgeon. Recurrence of common bile duct stones was diagnosed in 26 patients during a median follow-up of 4 years.

CONCLUSION

LTCBDE with or without microincision and/or lithotripsy is a safe and effective approach.

Laparoscopic common bile duct exploration: 15-year experience in a district general hospital

INTRODUCTION

The treatment of common bile duct (CBD) stones remains controversial with debate between endoscopic cholangiopancreatography (ERCP) and CBD exploration. A recent meta-analysis has shown no significant difference between these approaches; however, there is a trend in the literature to favour a single-stage procedure in the form of laparoscopic CBD exploration. We report our experience over a 15-year period.

METHODS

All cases of CBD exploration were identified from 2000 to 2015 and analysed retrospectively from a large NHS Foundation Trust in Northumbria. There were no exclusions. The mean clinical follow-up was 6 months (range 3-36 months).

RESULTS

A total of 296 patients were included who underwent laparoscopic CBD exploration: 203 were female and 93 were male. The mean age was 60 years (range 16-84 years). A total of 231 procedures were performed electively and 65 as an emergency. Ten procedures were successfully performed as day cases. Eleven procedures were converted to an open procedure due to adhesions or a difficult dissection (4 %). Sixty-three procedures were performed with a transcystic approach with a mean post-op stay of 2 days (range 0-7). A total of 233 procedures were performed with a choledocotomy with a mean post-op stay of 6 days (range 3-14 days). Stone clearance was successful in 255 patients (86 %). Three patients died over the study period. Two were for medical complications and one for abdominal sepsis. Three patients returned to theatre for early post-operative bleeding (1 %). Sixteen patients had persistent bile leaks following a choledocotomy (6.8 %). No patients had a bile leak following transcystic exploration. Fourteen patients were followed up following failed stone removal. Nine had a successful ERCP, three had no stone seen on MRCP, and one patient required re-operation following a failed ERCP.

CONCLUSIONS

Laparoscopic bile duct exploration can be performed successfully in both the emergency and elective settings. Day-case surgery is feasible in selected patients. A transcystic approach should be favoured where possible.

Clinical effect of conventional choledochotomy vs fiber choledochoscopy in treatment of biliary calculi

AIM: To compare the clinical efficacy and complications of conventional choledochotomy vs fiber choledochoscopy in the treatment of biliary calculi.

METHODS: Ninety patients with biliary calculi treated at our hospital from January 2008 to June 2013 were included in this study, of whom 40 received conventional choledochotomy (control group) and 50 received fiber choledochoscopy (observation group). The clinical efficacy and postoperative complications were compared between the two groups.

RESULTS: The surgical procedures were successful in all patients of the two groups. The amount of bleeding, anal exhaust time and hospital stay time were significantly lower in the observation group than in the control group (123.56 mL ± 9.45 mL vs 210.14 mL ± 10.26 mL, 29.63 h ± 2.35 h vs 46.20 h ± 2.18 h, 9.41 d ± 1.17 d vs 13.93 d ± 1.64 d, P < 0.05 for all). The rates of residual stones and recurrence were also significantly lower in the observation group than in the control group (2.00% vs 17.50%, 2.00% vs 15.00%, P < 0.05 for both).

CONCLUSION: Fiber choledochoscopy has advantages over conventional choledochotomy in treating biliary calculi in terms of lower bleeding, postoperative exhaust time, hospitalization time as well as reduced rates of residual stones and recurrence.

Short-term outcomes of laparoscopic transcystic common bile duct exploration with discharge less than 24 hours

BACKGROUND

Reducing the length of stay and discharge time for patients could benefit multiple hospital units by saving money, reducing waiting time, and providing the opportunity for more patients to be treated. However, no experience of laparoscopic transcystic common bile duct exploration (LTCBDE) with discharge less than 24 hours has been reported until now. The objective of this study was to assess the feasibility and safety of LTCBDE with discharge less than 24 hours.

PATIENTS AND METHODS

A retrospective review showed that 34 of 111 patients scheduled in our institution were discharged less than 24 hours after LTCBDE between June 1 and December 31, 2011. A multimodal approach including appropriate preoperative assessment, education and counseling, early postoperative oral intake, and early mobilization was carried out. Outcomes were analyzed for patient demographics, postoperative stay, operation time, intraoperative bleeding, and reasons for failed LTCBDE.

RESULTS

Of 111 patients admitted for LTCBDE, 34 patients were discharged within 24 hours postoperatively. This study population comprised 11 males and 23 females with a mean age of 54.6±14.7 years (range, 28-79 years). The mean postoperative stay was 20.21±0.39 hours. There were no postoperative complications or deaths during the hospital stay or at the follow-up 12 months postoperatively in these 34 patients.

CONCLUSIONS

LTCBDE with discharge less than 24 hours is feasible and safe in selected patients with common bile duct stones of no more than three in number and no more than 6 mm in size. The benefit of the multimodal approach and LTCBDE may be synergistic, allowing a quick recovery of gastrointestinal function.
