Risk Factors Associated With Residual Stones in Common Bile Duct Via T Tube Cholangiography After Common Bile Duct Exploration

Diagnostic value of T-tube cholangiography and choledochoscopy in residual calculi after biliary surgery

BACKGROUND

T-tube cholangiography and choledochoscopy are commonly used techniques for detecting residual bile duct stones after biliary surgery. However, the utility of routine cholangiography before T-tube removal needs further investigation. This study aims to evaluate the diagnostic efficacy of various methods for detecting residual calculi following biliary surgery.

METHODS

We retrospectively analyzed the clinical data of 287 adult patients who underwent common bile duct exploration with T-tube drainage, followed by T-tube cholangiography and choledochoscopy, at the Department of General Surgery, Xuanwu Hospital, Capital Medical University, between 2017 and 2022. Exclusion criteria were patients with bile duct tumors, incomplete medical records or loss to follow-up, and patients with contraindications to T-tube or choledochoscopy. McNemanr test and Kappa test were used to compare the results and consistency between choledochoscopy and T-tube cholangiography. All patients underwent both cholangiography and choledochoscopy six to eight weeks after laparoscopic cholecystectomy combined with common bile duct exploration and T-tube drainage. The results of T-tube cholangiography and choledochoscopy for each patient were recorded, analyzed, and compared.

RESULTS

Among the 287 patients, T-tube cholangiography detected residual stones in 38 cases, which were confirmed by choledochoscopy in 29 cases. Conversely, of the 249 patients without evidence of residual stones on T-tube angiography, 11 patient was later found to have retained stones through choledochoscopy. There was no significant difference between the results of T-tube cholangiography and choledochoscopy (P = 0.82), indicating a high level of agreement between the two methods (Kappa value: 0.70) (95% CI, 0.65-0.76).

CONCLUSION

There is no significant difference in the diagnostic accuracy between T-tube cholangiography and choledochoscopy for detecting residual bile duct stones after surgery (P = 0.82). The two methods demonstrated a high level of consistency (Kappa value: 0.70) (95% CI, 0.65-0.76). The choice of diagnostic method for postoperative residual bile duct stones should be based on the specific condition of the patient.

Surgical strategies for challenging common bile duct stones in the endoscopic era: A comprehensive review of current evidence

While endoscopic retrograde cholangiopancreatography (ERCP) remains the primary treatment modality for common bile duct stones (CBDS) or choledocholithiasis due to advancements in instruments, surgical intervention, known as common bile duct exploration (CBDE), is still necessary in cases of difficult CBDS, failed endoscopic treatment, or altered anatomy. Recent evidence also supports CBDE in patients requesting single-step cholecystectomy and bile duct stone removal with comparable outcomes. This review elucidates relevant clinical anatomy, selection indications, and outcomes to enhance surgical understanding. The selection between trans-cystic (TC) vs trans-choledochal (TD) approaches is described, along with stone removal techniques and ductal closure. Detailed surgical techniques and strategies for both the TC and TD approaches, including instrument selection, is also provided. Additionally, this review comprehensively addresses operation-specific complications such as bile leakage, stricture, and entrapment, and focuses on preventive measures and treatment strategies. This review aims to optimize the management of CBDS through laparoscopic CBDE, with the goal of improving patient outcomes and minimizing risks.

Risk factors analyses associated with postoperative infection in choledochoscopy for intrahepatic bile duct stones (IHDs): a single-center retrospective study in real-world setting

BACKGROUND

Choledochoscopy is a highly effective approach for managing intrahepatic bile duct stones (IHDs). However, postoperative infection is a common complication that significantly impacts treatment outcomes. Despite its clinical relevance, the risk factors associated with this procedure remain largely unexplored.

METHODS

This study focused on a consecutive cohort of patients who underwent choledochoscopy for IHDs at our institution between January 2016 and December 2022. The primary objective was to analyze the relationship between various clinical factors and postoperative infection, and to compare the postoperative infection of different choledochoscopic procedures.

RESULTS

The study cohort consisted of 126 patients, with 60 individuals (47.6%) experiencing postoperative infection. Notably, preoperative biliary obstruction (odds ratio [OR] 1.861; 95% confidence interval [CI] 1.314-8.699; p = 0.010) and operation time (OR 4.414; 95% CI 1.635-12.376; p = 0.004) were identified as risk factors for postoperative infection. Additionally, biliary tract infections (60.00%) were primarily responsible for postoperative infection, with Escherichia coli (47.22%) being the predominant bacterial strain identified in bile cultures. Furthermore, biliary tract obstruction (OR 4.563; 95% CI 1.554-13.401; p = 0.006) and body mass index (BMI) (OR 1.186; 95% CI 1.015-1.386; p = 0.031) were determined to be independent risk factors for postoperative biliary tract infection.

CONCLUSIONS

The occurrence of postoperative infection in patients undergoing choledochoscopy was primarily associated with the duration of the operation and the presence of preoperative biliary obstruction.

Application of a nurse-led transitional care programme for patients discharged with T-tubes after biliary surgery

AIM

Nurse-led transitional care programmes (TCPs) have been shown to facilitate patient recovery in several illness settings, but its role among patients discharged with T-tubes remains uncertain. The aim of the study was to investigate the effects of a nurse-led TCP among patients discharged with T-tubes.

DESIGN

This retrospective cohort study was conducted at a tertiary medical centre.

METHODS

From January 2018 to December 2020, a total of 706 patients discharged with T-tubes after biliary surgery were included in the study. Patients were divided into a TCP group (n = 255) and a control group (n = 451) based on whether they participated in a TCP. The baseline characteristics, discharge readiness, self-care ability, transitional care quality and quality of life (QoL) were compared between the groups.

RESULTS

Self-care ability and transitional care quality were significantly higher in the TCP group. Patients in the TCP group also exhibited improved QoL and satisfaction. The results suggest that the incorporation of a nurse-led TCP among patients discharged with T-tubes after biliary surgery is feasible and effective. No Patient or Public Contribution.

Evaluation of the Common bile duct (CBD) Diameter After Laparoscopic Cholecystectomy (LC) and Laparoscopic Common Bile Duct Exploration (LCBDE): A Retrospective Study

BACKGROUND

Common Bile duct (CBD) measurement is a crucial aspect in the evaluation of the biliary tree. Whether the CBD undergoes any compensatory change in diameter after laparoscopic cholecystectomy or laparoscopic common bile duct exploration is still up for discussion. The aim of this study was to investigate CBD diameter changes after laparoscopic cholecystectomy (LC) and laparoscopic common bile duct exploration (LCBDE) on magnetic resonance cholangiopancreatography (MRCP).

MATERIALS AND METHODS

Our retrospective study is divided into 2 sections. The first part assessing CBD diameter changes after laparoscopic cholecystectomy due to gallstones or gallbladder polyps, involved 85 patients, who underwent MRCP procedures. These patients aged between 30 and 85 were divided into an interval LC group (group A, n=56) and a remote LC group (group B, n=29). In group A, the common CBD diameters were measured at their widest portions on MRCP obtained before and after laparoscopic cholecystectomy. Measurements of the CBD diameters were repeated on MRCP obtained twice after the surgery in group B.Section 2 consisted of 38 patients who had choledocholithiasis and were treated with laparoscopic CBD exploration and T-tube placement. These patients aged 26 to 86 formed the interval LCBDE group (group C). The CBD widest diameters were measured on MRCP before LCBDE and after T-tube cholangiography for these individuals.Patients in groups A and C were further divided into 5 and those in group B into 4 age-related subgroups to facilitate statistical analysis. The Pearson correlation test was performed to find any relationship between CBD diameters and age in groups A and B. Paired sample T test was used to compare the significant difference between the 2 sets of CBD diameters in each study group and their subgroups.

RESULTS

In the interval LC group, the post-LC mean CBD diameter was significantly wider when compared with the preoperative mean diameter ( P <0.05). There was a significant difference between the first and second post-LC means CBD diameter in the remote LC group ( P <0.05). In group C, the mean CBD diameter measured on T-tube cholangiography after LCBDE was significantly smaller than the preoperative dilated mean diameter ( P <0.05).

CONCLUSIONS

This study demonstrated significant dilation occurring in the common bile duct diameter after laparoscopic cholecystectomy. Furthermore, our remote LC group also supported that claim by showing significant dilation between the first and second post-cholecystectomy CBD diameter values. And lastly, our interval LCBDE sample's initial dilation of the CBD diameters was reduced after surgery and stone extraction.

Residual choledocholithiasis after choledocholithotomy T-tube drainage: what is the best intervention strategy?

BACKGROUND

The best intervention approach for residual choledocholithiasis after choledocholithotomy T-tube drainage remains controversial, especially during the period of indwelling T tube and the formation of a sinus. The purpose of the study was to estimate the effects of two therapeutic modalities, namely endoscopic retrograde cholangiopancreatography (ERCP) and choledochfiberscope via the T-tube sinus tract (CDS) on residual choledocholithiasis after choledocholithotomy T-tube drainage.

METHODS

A total of 112 patients with residual choledocholithiasis after choledochotomy were included in the study, 50 of which underwent ERCP and 62 patients experienced choledochoscopy via the T-tube sinus tract. The primary outcome measures included the success rate of remove biliary stones, T-tube drainage time, and the average length of hospital stay. The secondary objective was to consider incidence of adverse events including cholangitis, bile leakage, T-tube migration, pancreatitis, bleeding and perforation. After hospital discharge, patients were followed up for two years and the recurrence of choledocholithiasis was recorded.

RESULTS

There was no significant difference in the success rate of stone removal between the two groups. Compared to CDS group, T-tube drainage time and the average length of hospital stay was significantly shorter in the ERCP group. The incidence of complications (cholangitis and bile leakage) in the ERCP group was lower than that in the CDS group, but there was no statistically significant difference. When the T-tube sinus tract is not maturation, ERCP was the more appropriate endoscopic intervention to remove residual choledocholithiasis, particularly complicated with cholangitis at this time period.

CONCLUSIONS

ERCP is a safe and effective endoscopic intervention to remove residual choledocholithiasis after choledocholithotomy T-tube Drainage without the condition of T-tube sinus tract restriction.

Percutaneous Management of Biliary Stones

Bile duct stone disease is the most common causes of nonmalignant bile duct obstructions. The range of common bile duct stone formation in patients with cholecystectomy is 3 to 14.7%. Hepatolithiasis, although endemic in some parts of the world, is a rare disease that is difficult to manage. Endoscopic intervention is accepted as the first-line management of common bile duct stones. However, when the bile duct cannot be cannulated for various reasons, the endoscopic procedure fails. In this circumstance, percutaneous approach is an alternative technique for the nonsurgical treatment of bile duct stones. This article reviews the indications, technique, outcomes, and complications of the percutaneous treatment of bile duct stone disease.

A Novel Remote-Controlled Injection Device for T-Tube Cholangiography: A Feasibility Study in Canines

Backgroun

The purpose of this study was to develop a remote-controlled injection device for T-tube cholangiography to avoid occupational exposure.

Material/Methods

The remote-controlled injection device has 3 major components: an injection pump, a pressure sensor, and a wireless remote-control panel. The feasibility and effectiveness of this device for T-tube cholangiography was evaluated in ex vivo porcine livers using a laparoscopic training platform and in in vivo canine experiments.

Results

The contrast dye was successfully injected into the biliary tracts of the ex vivo porcine liver and canines by the designed device. The X-ray images clearly showed the anatomical structure of the bile ducts. No obvious adverse reaction was observed in the dogs during or after the procedure. All steps were controlled remotely, avoiding ionizing radiation exposure to the surgeons.

Conclusions

This novel remote-controlled injection device for T-tube cholangiography can assist operators in completing cholangiography remotely and protecting them from occupational exposure.

Percutaneous management of residual bile duct stones through T-tube tract after cholecystectomy: A retrospective analysis of 89 patients

PURPOSE

The purpose of this study was to analyze the outcome of percutaneous management of residual common bile duct (CBD) stones in patients with surgically inserted T-tube in CBD after cholecystectomy.

MATERIAL AND METHODS

Between April 2001 and August 2015, 89 patients (52 women, 37 men) with a mean age of 55.7 years±18 (SD) (range, 22-88 years) underwent percutaneous sphincteroplasty and stone expulsion into the duodenum with a Fogarty balloon catheter through the T-tube tract for residual CBD stones. All patients had previously undergone open cholecystectomy with CBD exploration and T-tube insertion 7 to 60 days (mean, 14.4 days) before the procedure. Results of the procedure and complications were evaluated by a review of clinical notes, imaging and laboratory findings.

RESULTS

The procedure was successful in 87/89 patients (97.7%). Complete CBD clearance was achieved in a first session in 86 patients (96.6%). One patient (1.1%) needed a second session. The procedure was unsuccessful in 2 patients (2.2%) due to inappropriate position of T-tube and stone impaction into the cystic duct remnant. Two complications (2.2%) including intra-abdominal bile collection and distal CBD stricture were observed after the procedure.

CONCLUSION

Percutaneous CBD expulsion into the duodenum through the T-tube tract is a non-traumatic, effective and safe method for the treatment of residual CBD stones in patients who had cholecystectomy and T-tube insertion.

Design and clinical application of a double lumen T tube

AIM: To design a double lumen T tube, investigate its hydrodynamic characteristics, and assess its clinical application.

METHODS: A retrospective study was carried out to analyze the data of patients who underwent biliary tract operations with placement of a double lumen T tube from March 1989 to March 2015 at the Department of Hepatobiliary Surgery of Binzhou Medical University Hospital. This study introduced the design, placement and operational method of the double lumen T tube, investigated its hydrodynamic characteristics, analyzed the complications, and assessed its clinical application in biliary tract irrigation, bile culture, cholangiography and enteral nutrition.

RESULTS: Based on the function of double lumen T tube, it was divided into two types: Ⅰ (for biliary irrigation) and type Ⅱ (for enteral nutrition). For type Ⅰ double lumen T tube, the short arm was placed in the extrahepatic bile duct, and the long arm was brought out through the abdominal wall; the inner tube was placed in left or right secondary or tertiary intrahepatic bile duct, with the end outside the body connected to saline for flushing. For type Ⅱ double lumen T tube, the short arm was placed in the extrahepatic bile duct, and the long arm was brought out through the abdominal wall; the inner tube was placed into the duodenum or jejunum through the duodenal papilla or anastomotic stoma, with the end outside the body connected to nutrition solution for enteral nutrition. A total of 1020 patients underwent placement of the double lumen T tube, including 660 who used type Ⅰ and 360 who used type Ⅱ tube. T tube placement time was 5-92 d, with an average value of 23.5 d. Complications included T tube dislocation (2 cases, 0.20%), lumen blockage (12 cases, 1.18%), infection around T tube (23 cases, 2.26%), hemobilia (2 cases, 0.2%), difficulty in removing (1 case, 0.10%), biliary fistula (11 cases, 1.08%), and peritonitis after T tube removal (2 cases, 0.20%). Moreover, 665 cases underwent biliary tract irrigation, and bile culture was performed in 343 cases; the positive rate of bacteria culture was lower than that observed in patients using conventional T tube. In 657 cases who underwent cholangiography, the rate of satisfaction was 98.2%. 358 cases accepted enteral nutrition with type Ⅱ double lumen T tube, and 314 cases underwent simultaneous bile external drainage and pancreatic juice reinfusion.

CONCLUSION: The double lumen T tube is easily made and convenient to use with lower complications. It can be safely used for biliary flushing, bile culture, cholangiography and enteral nutrition after biliary tract operations.

Efficacy of laparoscopic vs open common bile duct exploration in patients with choledocholithiasis

AIM: To compare the efficacy between laparoscopic and open common bile duct exploration in patients with choledocholithiasis.

METHODS: Ninety-six patients with choledocholithiasis were divided into a study group (50 cases) and a control group (46 cases). The study group received laparoscopic common bile duct exploration, and the control group received open common bile duct exploration. The operative situation, postoperative situation, and complications were compared for the two groups.

RESULTS: There was no significant difference in operative time or bleeding volume between the two groups (130.33 min ± 11.06 min vs 128.68 min ± 10.88 min, 68.86 mL ± 10.97 mL vs 70.92 mL ± 11.26 mL, P > 0.05). The number of times of postoperative analgesia use, time to gastrointestinal function recovery, postoperative hospitalization duration, and total treatment cost for the study group were significantly lower than those for the control group (1.27 ± 0.50 vs 1.68 ± 0.72, 29.82 h ± 5.69 h vs 34.91 h ± 5.70 h, 7.22 d ± 1.15 d vs 10.11 d ± 1.33 d, 10068.44 ± 113.08 vs 13025.75 ± 116.20, P < 0.05). The rate of incision infection for the experiment group was significantly lower than that for the control group (0.00% vs 8.70%, P < 0.05).

CONCLUSION: Laparoscopic common bile duct exploration is associated with less surgical trauma, shorter postoperative recovery time and lower treatment cost than open common bile duct exploration in patients with choledocholithiasis.
