Surgical methods of treatment for cholecystolithiasis combined with choledocholithiasis: six years' experience of a single institution

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

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

Experience in laparoscopic transcystic common bile duct exploration for super-elderly patients with choledocholithiasis-A 96-year-old case report

Background

Super-elderly patients with choledocholithiasis are considered to be at high risk for undergoing surgery. While laparoscopic transcystic common bile duct exploration (LTCBDE) is regarded as a challenging procedure for super-elderly patients with choledocholithiasis, there have been no reported cases of its use in super-elderly patients over the age of 96.

Case summary

This case study presents the case of a 96-year-old female patient with acute calculous cholecystitis and choledocholithiasis. Despite the presence of multiple high-risk comorbidities, the patient underwent with laparoscopic cholecystectomy (LC) plus LTCBDE, with appropriate perioperative safety measures in place, and made a full recovery, being discharged from the hospital on the seventh day following the operation.

Conclusion

The case study demonstrates the successful treatment of a 96-year-old patient with choledocholithiasis via LTCBDE, utilising skilled laparoscopic and choledochoscopic techniques along with robust perioperative safety measures. This achievement sets a historical precedent for the successful treatment of a 96-year-old patient with choledocholithiasis via LTCBDE, both domestically and internationally.

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

Background

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

Methods

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

Results

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

Conclusions

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

Can laparoscopic common bile duct exploration be performed without any drainage? A propensity score-matched study

INTRODUCTION

Although laparoscopic common bile duct exploration (LCBDE) is considered a safe and effective method for treating choledocholithiasis, the absence of any biliary or abdominal drainage during surgery remains controversial.

AIM

This paper aims to investigate the feasibility and safety of LCBDE without drainage, particularly abdominal drainage.

MATERIALS AND METHODS

This retrospective analysis included 499 patients who underwent LCBDE with primary closure of the common bile duct and without any kind of biliary drainage during surgery. In 322 individuals, the surgery involved routine abdominal drainage (drainage group), whereas in 177 cases, no abdominal drainage was performed (nondrainage group). Baseline characteristics of the 2 groups were compared, followed by propensity score matching (PSM) to balance confounding factors. We compared effect indicators and complication rates between both groups.

RESULTS

After PSM, each group included 124 patients. There were no significant differences between the 2 groups in terms of overall and individual complication rates, except for a lower incidence of hyperamylasemia in the nondrainage group. The surgery time, duration of postoperative antibiotic use, and the total and postoperative length of hospital stay was significantly shorter in the nondrainage group. Similarly, the total hospitalization cost and postoperative usage of analgesics and antispasmodics were also considerably lower in the nondrainage group.

CONCLUSIONS

Nondrainage LCBDE is associated with shorter recovery time and better patient outcomes, as compared with procedures involving abdominal drainage. In suitable cases, this approach is completely safe and feasible.

Laparoscopic cholecystectomy plus common bile duct exploration for extrahepatic bile duct stones and postoperative recurrence-associated risk factors

BACKGROUND

There remain controversies regarding the surgical treatment of extrahepatic bile duct stones (EHBDSs) in clinical practice.

AIM

To explore the curative effect of laparoscopic cholecystectomy (LC) plus common bile duct exploration (CBDE) for the surgical treatment of EHBDSs and to analyze the risk factors that affect postoperative stone recurrence.

METHODS

Eighty-two patients with EHBDSs admitted between March 2017 and March 2023 were selected. Among them, patients treated with open choledocholithotomy plus LC or open cholecystectomy (OC) were set as the control group (n = 40), and those treated with LC plus CBDE served as the observation group (n = 42). The surgical outcomes of the two groups were compared, the surgical complications and Gastrointestinal Quality of Life Index (GIQLI) scores were counted, and the one-year prognostic recurrence was recorded. Independent factors for postoperative recurrence were determined using univariate and multivariate analyses.

RESULTS

The two groups were comparable in the stone residual rate (P > 0.05). The operation time (P < 0.05), intraoperative bleeding (P < 0.05), and total complication rate (P = 0.005) were lower in the observation group than in the control group. The observation group exhibited a marked increase in the GIQLI score, which was higher than the control group (P < 0.05). A lower one-year recurrence rate was determined in the observation group vs the control group (P = 0.027). Sphincter of Oddi dysfunction [odds ratio (OR) = 5.712, P = 0.007] and the treatment scheme of open choledocholithotomy plus LC or OC (OR = 6.771, P = 0.008) were the independent risk factors for one-year recurrence in patients after surgery.

CONCLUSION

LC plus CBDE for patients with EHBDSs can reduce stone residuals, intraoperative bleeding, complications, and postoperative recurrence.

Clinical efficacy of laparoscopic cholecystectomy plus cholangioscopy for the treatment of cholecystolithiasis combined with choledocholithiasis

BACKGROUND

Currently, endoscopic retrograde cholangiopancreatography (ERCP) plus laparoscopic cholecystectomy (LC) is the main treatment for cholecystolithiasis combined with choledocholithiasis. However, the treatment is unsatisfactory, and the development of better therapies is needed.

AIM

To determine the clinical efficacy of LC plus cholangioscopy for cholecystolithiasis combined with choledocholithiasis.

METHODS

Patients (n = 243) with cholecystolithiasis and choledocholithiasis admitted to The Affiliated Haixia Hospital of Huaqiao University (910th Hospital of Joint Logistic Support Force) between January 2019 and December 2023 were included in the study; 111 patients (control group) underwent ERCP + LC and 132 patients (observation group) underwent LC + laparoscopic common bile duct exploration (LCBDE). Surgical success rates, residual stone rates, complications (pancreatitis, hyperamylasemia, biliary tract infection, and bile leakage), surgical indicators [intraoperative blood loss (IBL) and operation time (OT)], recovery indices (postoperative exhaust/defecation time and hospital stay), and serum inflammatory markers [C-reactive protein (CRP), tumor necrosis factor-α (TNF-α), and interleukin-6 (IL-6) were compared.

RESULTS

No significant differences in surgical success rates and residual stone rates were detected between the observation and control groups. However, the complication rate, IBL, OT, postoperative exhaust/defecation time, and hospital stays were significantly reduced in the observation group compared with the control group. Furthermore, CRP, TNF-α, and IL-6 Levels after treatment were reduced in the observation group compared with the levels in the control group.

CONCLUSION

These results indicate that LC + LCBDE is safer than ERCP + LC for the treatment of cholecystolithiasis combined with choledocholithiasis. The surgical risks and postoperative complications were lower in the observation group compared with the control group. Thus, patients may recover quickly with less inflammation after LCBDE.

Features of Metabolite Changes in Disease Evolution in Cholecystolithiasis

BACKGROUND

Cholecystolithiasis is defined as a disease caused by complex and changeable factors. Advanced age, female sex, and a hypercaloric diet rich in carbohydrates and poor in fiber, together with obesity and genetic factors, are the main factors that may predispose people to choledocholithiasis. However, serum biomarkers for the rapid diagnosis of choledocholithiasis remain unclear.

AIMS

This study was designed to explore the pathogenesis of cholecystolithiasis and identify the possible metabolic and lipidomic biomarkers for the diagnosis of the disease.

METHODS

Using UHPLC-MS/MS and GC-MS, we detected the serum of 28 cholecystolithiasis patients and 19 controls. Statistical analysis of multiple variables included Principal Component Analysis (PCA). Visualization of differential metabolites was performed using volcano plots. The screened differential metabolites were further analyzed using clustering heatmaps. The quality of the model was assessed using random forests.

RESULTS

In this study, dramatically altered lipid homeostasis was detected in cholecystolithiasis group. In addition, the levels of short-chain fatty acids and amino acids were noticeably changed in patients with cholecystolithiasis. They detected higher levels of FFA.18.1, FFA.20.1, LPC16.0, and LPC20.1, but lower levels of 1-Methyl-L-histidine and 4-Hydroxyproline. In addition, glycine and L-Tyrosine were higher in choledocholithiasis group. Analyses of metabolic serum in affected patients have the potential to develop an integrated metabolite-based biomarker model that can facilitate the early diagnosis and treatment of the disease.

CONCLUSION

Our results highlight the value of integrating lipid, amino acid, and short-chain fatty acid to explore the pathophysiology of cholecystolithiasis disease, and consequently, improve clinical decision-making.

Does previous gastrectomy history affect the surgical outcomes of laparoscopic cholecystectomy?

PURPOSE

This current study aimed to explore whether gastrectomy history influenced surgical outcomes while undergoing laparoscopic cholecystectomy (LC).

METHODS

The PubMed, Embase, and Cochrane Library databases were searched for eligible studies from inception to April 29, 2023. The Newcastle-Ottawa Scale (NOS) was adopted to assess the quality of included studies. The mean differences (MDs) and 95% confidence intervals (CIs) were calculated for continuous variables, and the odds ratios (ORs) and 95% CIs were calculated for dichotomous variables. RevMan 5.4 was used for data analysis.

RESULTS

Seven studies enrolling 8193 patients were eligible for the final pooling up analysis (380 patients in the previous gastrectomy group and 7813 patients in the non-gastrectomy group). The patients in the gastrectomy group were older (MD = 11.11, 95%CI = 7.80-14.41, P < 0.01) and had a higher portion of males (OR = 3.74, 95%CI = 2.92-4.79, P < 0.01) than patients in the non-gastrectomy group patients. Moreover, the gastrectomy group had longer LC operation time (MD = 34.17, 95%CI = 25.20-43.14, P < 0.01), a higher conversion rate (OR = 6.74, 95%CI = 2.17-20.26, P = 0.01), more intraoperative blood loss (OR = 1.96, 95%CI = 0.59-3.32, P < 0.01) and longer postoperative hospital stays (MD = 1.07, 95%CI = 0.38-1.76, P < 0.01) than the non-gastrectomy group.

CONCLUSION

Patients with a previous gastrectomy history had longer operation time, a higher conversion rate, more intraoperative blood loss, and longer postoperative hospital stays than patients without while undergoing LC. Surgeons should pay more attention to these patients and make prudent decisions to avoid worse surgical outcomes as much as possible.

Current management of concomitant cholelithiasis and common bile duct stones

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

Comparison of efficacy and safety of robotic surgery and laparoscopic surgery for choledochal cyst in children: a systematic review and proportional meta-analysis

BACKGROUND

Most commonly, cyst excision and Roux-en-Y hepaticojejunostomy reconstruction are the optimal treatment for choledochal cysts (CC). Robotic surgery (RS) is being conducted with increasing frequency to treat CC. It is unclear whether RS can overcome the limitations of laparoscopic surgery (LS) and improve the prognosis of patients. In terms of efficacy, evidence concerning which minimally invasive surgery is preferred is, however, sparse. Our objective is to further compare the efficacy of RS and LS in children with CC and draw a useful clinical conclusion.

METHODS

Studies meeting inclusion criteria were identified from a series of databases, consisting of PubMed, Embase, Scopus, Web of Science, the Cochrane Library and their reference list of articles up to May 2022. Eligible articles comprised at least five objects that were younger than 18 years of age and the language was limited to English. Two authors independently evaluated selected studies and extracted data for analysis.

RESULTS

Forty studies were selected for analysis, with thirty-six reporting data on LS and eight containing data on RS. The pooled conversion rate and pooled postoperative complication rate of RS were lower than those of LS, but none of them was statistically significant. Moreover, comparisons of the following detailed postoperative complication rates were not statistically significant, such as intestinal obstruction or ileus, anastomotic bleeding, anastomotic or bile leakage, and anastomotic stenosis. However, the intraoperative blood loss and the postoperative hospital stay in RS group were significantly lower than those in LS group.

CONCLUSIONS

RS is a safe and feasible option for children with CC. Further studies with more cases, long-term efficacy and health economics analysis are needed to confirm whether RS is more advantageous.

Safety and Feasibility of Primary Closure Following Laparoscopic Common Bile Duct Exploration for Treatment of Choledocholithiasis

BACKGROUND

T-tube drainage following laparoscopic common bile duct (CBD) exploration may lead to T-tube displacement and water-electrolyte disorders, affecting patients' quality of life. In particular, biliary peritonitis may develop in a small number of patients after T-tube removal, requiring reoperation. This prospective cohort study was performed to investigate the safety and feasibility of primary closure following laparoscopic CBD exploration for the treatment of choledocholithiasis.

METHODS

Patients who were treated for choledocholithiasis by laparoscopic CBD exploration with primary closure from January 2019 to March 2022 comprised the PC group (n = 145). Patients who were treated for choledocholithiasis by laparoscopic CBD exploration with T-tube drainage during this period comprised the TD group (n = 153). Perioperative and follow-up outcomes were collected and statistically analyzed.

RESULTS

The TD and PC groups showed significant differences in the operation time (124.6 ± 40.8 vs. 106 ± 36.4 min, P = 0.000) and postoperative hospital stay (7.1 ± 2.6 vs. 5.9 ± 2.0 days, P = 0.000). No significant difference was observed in terms of blood loss, the ratio of conversion to laparotomy, and postoperative parameters. Preoperative albumin and total bilirubin levels were the risk factors of bile leakage after surgery. No patients developed CBD stricture or carcinogenesis, The rates of residual and recurrent stones in the TD and PC groups were 1.97% vs. 1.40% and 1.31% vs. 1.40%, respectively, with no significant difference (P = 1.000 for both).

CONCLUSIONS

Primary closure following laparoscopic CBD exploration is safe and feasible for selected patients with choledocholithiasis.

The Laparoscopic Cholecystectomy and Common Bile Duct Exploration: A Single-Step Treatment of Pediatric Cholelithiasis and Choledocholithiasis

BACKGROUND

In recent years, complicated biliary tract diseases are increasingly diagnosed in children. Laparoscopic exploration of the common bile duct (LCBDE) followed by laparoscopic cholecystectomy has gained popularity in children. The aim of this study was to investigate the outcomes of LCBDE in children and compare them with the treatment outcomes of previously used endoscopic retrograde cholangiopancreatography (ERCP).

METHODS

From January 2000 to January 2022, a total of 84 children (78.5% female) underwent laparoscopic cholecystectomy with a median follow-up of 11.4 (IQR 8, 14) years. Of these, 6 children underwent laparoscopic cholecystectomy (LC) + ERCP and 14 children underwent LCBDE for choledochiothiasis. The primary end point of the study was the success of treatment in terms of the incidence of complications, recurrence rate, and rate of reoperation. Secondary endpoints were stone characteristics, presenting symptoms, duration of surgery, and length of hospital stay.

RESULTS

The majority of patients were female in both groups (83.5% vs. 85.7%), mostly overweight with a median BMI of 27.9 kg/m² and 27.4 kg/m², respectively. Obstructive jaundice, colicky pain, acute pancreatitis, and obstruction of the papilla were the most common symptoms in both groups. The majority of patients (68%) had one stone, whereas two or more stones were found in 32% of patients. The median diameter of the common bile duct was 9 mm in both groups. The procedure was successfully completed in all patients in the ERCP group. In the group of patients treated with LCBDE, endoscopic extraction of the stone with a Dormia basket was successfully performed in ten patients (71.4%), while in the remaining four patients (28.6%) the stones were fragmented with a laser because extraction with the Dormia basket was not possible. The median operative time was 79 min in the LCBDE group (IQR 68, 98), while it was slightly longer in the ERCP group, 85 min (IQR 74, 105) (p = 0.125). The length of hospital stay was significantly shorter in the LCBDE group (2 vs. 4 days, p = 0.011). No complications occurred in the LCBDE group, while two (40%) complications occurred in the ERCP group: pancreatitis and cholangitis (p = 0.078). During the follow-up period, no conversions, papillotomies, or recurrences were recorded in either group.

CONCLUSIONS

Exploration of the common bile duct and removal of stones by LCBDE is safe and feasible in pediatric patients for the treatment of choledocholithiasis. Through this procedure, choledocholithiasis and cholelithiasis can be treated in a single procedure without papillotomy or fluoroscopy. Compared with LC + ERCP, LCBDE is associated with a shorter hospital stay. The incidence of complications was rather low but not statistically significant.

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

BACKGROUND

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

MATERIALS AND METHODS

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

RESULTS

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

CONCLUSION

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

Evaluation of therapeutic efficacy, safety and economy of ERCP and LTCBDE in the treatment of common bile duct stones

Objectives: This study further compared the endoscopic retrograde cholangiopancreatography (ERCP) and laparoscopic transcystic common bile duct exploration (LTCBDE) approaches in the treatment of common bile duct stones (CBDS) from the perspective of efficacy, safety and economy.

Methods: The therapeutic efficacy and safety of ERCP and LTCBDE approaches were retrospectively compared. Cost-effectiveness analysis of clinical economics was performed to analyze and evaluate the two approaches.

Results: There was no significant difference in the success rate of surgery and bile stone residue between ERCP and LTCBDE group. The incidence of postoperative complications in ERCP group was significantly higher than that in the LTCBDE group; while the incidence of pancreatitis in the ERCP group was significantly higher than that in the LTCBDE group. There was no significant difference in biliary infection, bile leakage and sepsis between ERCP and LTCBDE groups. In terms of cost, the costs of surgery and nursing were significantly lower, the costs of treatment and sanitary materials were significantly higher in the ERCP group than that in the LTCBDE group. There was no significant difference in the costs of medical examination, laboratory test, medicine cost and total cost between ERCP group and LTCBDE group. The total length of hospital stay, length of hospital stay before surgery and duration of surgery in the ERCP group were significantly lower than that in the LTCBDE group; there was no significant difference in length of hospital stay after surgery between the ERCP and LTCBDE group. The cost-effectiveness ratio of ERCP group was 34171.25, and the cost-effectiveness of LTCBDE group was 34524.25. The incremental cost-effectiveness ratio (ICER) of the two groups was 51415.

Conclusion: ERCP and LTCBDE approaches had similar therapeutic efficacy in the treatment of CBDS. The safety of LTCBDE approach is superior to that of ERCP approach for the treatment of CBDS. ERCP approach is more economical in the treatment of CBDS than LTCBDE approach.
