Biliary Tract Exploration After Laparoscopic Left-sided Hepatectomy: A Comparative Study of Left Hepatic Duct Orifice Versus Common Bile Duct Approach

BACKGROUND

Laparoscopic left-sided hepatectomy (LLH) and additional biliary tract exploration are effective methods to treat left-sided hepatolithiasis (LSH) combined with extrahepatic bile duct stones. Although biliary tract exploration through common bile duct (CBD) incision has been widely accepted, the safety and effectiveness of the left hepatic duct (LHD) orifice approach after LLH is still in debate.

METHODS

One hundred and forty-four patients with LSH who underwent LLH and biliary tract exploration in our institution from April 2014 to September 2021 were enrolled in the retrospectively study. They were divided into 3 groups: LHD group (n=67), CBD/T-tube group (n=58), and CBD/PC group (n=19). Patients' demographic characteristics, intraoperative, and postoperative outcomes were retrospectively analyzed.

RESULTS

LHD group exhibited a shorter operative time (202.8±42.2 vs. 232.7±47.5 min, P=0.000), time to first bowel movement (2.3±0.5 vs. 2.9±0.7 d, P=0.000) and postoperative hospital stay (7.5±2.1 vs. 9.8±5.2 d, P=0.001) compared with the CBD/T-tube group. The lithotomy time in the LHD group was significantly longer than that in the CBD/T-tube group (33.6±7.3 vs. 29.0±6.3 min, P=0.000) and CBD/PC group (33.6±7.3 vs. 28.7±3.7, P=0.006). Intraoperative blood loss, blood transfusion rate, initial stone clearance rate, and stone recurrence rate all had no significant differences between the 3 groups (all P>0.05). LHD group showed less rate of electrolyte imbalance than that of the CBD/T-tube group (3.0% vs. 19.0%, P=0.004) but it was equivalent to the CBD/PC group (P>0.05). The type of biliary tract exploration (odds ratio: 5.43, 95% confidence interval: 0.04-0.95, P=0.032) as independent predictors of electrolyte imbalance. No reoperation and mortality occurred in the 3 groups. The conversion rate was comparable among 3 groups (1.5% vs. 1.7% vs. 0, all P>0.05). No significant difference in stone recurrence rate was seen (1.5% vs. 3.4% vs. 0, all P>0.05).

CONCLUSION

Biliary tract exploration through LHD orifice after LLH is a safe and effective treatment for selected patients with LSH, with an advantage over the T-tube drainage in the field of operative time, the incidence of electrolyte imbalance, recovery of gastrointestinal function, and postoperative hospital stay.

Comparative study of three common bile duct closure techniques after choledocholithotomy: safety and efficacy

PURPOSE

T-tube drainage, primary closure, and biliary stenting are the common bile duct closure methods. There is great debate on the optimal duct closure technique after common bile duct exploration. This study aimed to assess the safety and efficacy of the three commonest common bile duct closure methods after common bile duct exploration for common bile duct stone for future generalization.

METHODS

In this analysis, 211 patients with common bile duct stone underwent common bile duct exploration from January 2016 to December 2020. The patients were divided according to common bile duct closure techniques into three groups, including the T-tube drainage group (63 patients), primary duct closure group (61 patients), and antegrade biliary stenting group (87 patients).

RESULTS

The incidence of overall biliary complications and bile leak were statistically significantly lower in the biliary stenting group than in the other two groups. Also, hospital stays, drain carried time, return to normal activity, re-intervention, and re-admission rates were statistically significantly lower in the biliary stenting group than in the other two groups. There were no statistically significant differences regarding operative and choledochotomy time, retained and recurrent stone, stricture, biliary peritonitis, cholangitis, and the cost among the three groups.

CONCLUSIONS

We state that the biliary stenting procedure should be the preferred first option for common bile duct closure after common bile duct exploration when compared with T-tube drainage and primary duct closure.

Management of cholelithiasis with choledocholithiasis: Endoscopic and surgical approaches

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

Implementation of a simplified self-releasing biliary stent in choledocholithiasis: Experience in 150 cases

INTRODUCTION

Our aim was to introduce a simple way of making a self-releasing biliary stent for laparoscopic common biliary duct exploration.

METHODS

To make a self-releasing biliary stent, an absorbable thread was sutured to a J-shape polyurethane biliary stent. After the evacuation of the calculi, a guide wire was placed into the duodenum antegradely, facilitating the insertion of the biliary stent. The pigtail of the stent was left in the duodenum. The choledochotomy was then sutured, with the absorbable thread left outside the bile duct.

RESULTS

This study consisted of 150 patients with choledocholithiasis. The mean operating time was 126 ± 36 minutes. The postoperative hospital stay was 6.5 ± 3.6 days. In 149 cases, the biliary stents were released and discharged out of the body with feces. The inside body time of the rapid-releasing stent was 13.6 ± 2.6 days, and it was 28.0 ± 4.6 days for the slow-releasing stent. One stent was removed by endoscopy. Transient hyperamylasemia occurred in 32 patients (21.3%) without clinical onset of pancreatitis. Bile leakage occurred in three patients (2.0%), all of whom recovered after treatment. Residual lithiasis was found in one patient (0.7%) and was retracted by endoscopy 30 days after the first procedure. No infection or dislocation of the stent was found.

CONCLUSION

For laparoscopic common biliary duct exploration for choledocholithiasis, this method provides an alternative way to make a simple and safe self-releasing stent. It enables the endoscopic retraction of biliary stents to be avoided.

Comprehensive and innovative techniques for laparoscopic choledocholithotomy: A surgical guide to successfully accomplish this advanced manipulation

Surgeries for benign diseases of the extrahepatic bile duct (EHBD) are classified as lithotomy (i.e., choledocholithotomy) or diversion (i.e., choledochojejunostomy). Because of technical challenges, laparoscopic approaches for these surgeries have not gained worldwide popularity. The right upper quadrant of the abdomen is advantageous for laparoscopic procedures, and laparoscopic choledochojejunostomy is safe and feasible. Herein, we summarize tips and pitfalls in the actual procedures of choledocholithotomy. Laparoscopic choledocholithotomy with primary closure of the transductal incision and transcystic C-tube drainage has excellent clinical outcomes; however, emergent biliary drainage without endoscopic sphincterotomy and preoperative removal of anesthetic risk factors are required. Elastic suture should never be ligated directly on the cystic duct. Interrupted suture placement is the first choice for hemostasis near the EHBD. To prevent progressive laceration of the EHBD, full-layer interrupted sutures are placed at the upper and lower edges of the transductal incision. Cholangioscopy has only two-way operation; using dedicated forceps to atraumatically grasp the cholangioscope is important for smart maneuvering. The duration of intraoperative stone clearance accounts for most of the operative time. Moreover, dedicated forceps are an important instrument for atraumatic grasping of the cholangioscope. Damage to the cholangioscope requires expensive repair. Laparoscopic approach for choledocholithotomy involves technical difficulties. I hope this document with the visual explanation and literature review will be informative for skillful surgeons.

Primary Closure Following Laparoscopic Common Bile Duct Exploration Combined with Intraoperative Choledochoscopy and D-J Tube Drainage for Treating Choledocholithiasis

BACKGROUND This study aimed to assess the clinical short-term results of a primary closure following laparoscopic common bile duct exploration (LCBDE) combined with intraoperative choledochoscopy and D-J tube drainage for choledocholithiasis treatment. MATERIAL AND METHODS Twenty-five patients (14 women and 11 men) who underwent LCBDE with primary duct closure and D-J tube drainage for choledocholithiasis were retrospectively enrolled. The D-J tube (4.7F×14 cm) was removed using a duodenoscope if there was no bile leakage. Before discharge, patients were examined for blood amylase. After discharge or D-J tube removal, all patients were routinely assessed for complications. RESULTS Mean operating time was 135±46 min (range, 78-195 min). Mean intraoperative blood loss was 71±24 mL (range, 25-110 mL). Total hospital stay was 6-9 days (mean, 8.04±1.37 days). Two patients experienced intraoperative bile leakage, which was stopped with re-suturing. None of these patients experienced postoperative bile leaks. Three patients had slight elevation of serum amylase before discharge but without pancreatitis signs. The successful clearance rate of stones was 100%. During 1-year follow-up, no recurrence or severe complications occurred. CONCLUSIONS A primary closure following LCBDE combined with intraoperative choledochoscopy and D-J tube drainage is safe and feasible for choledocholithiasis treatment.

A 23 year experience with laparoscopic common bile duct exploration

BACKGROUND

Laparoscopic common bile duct exploration (LCBDE) during laparoscopic cholecystectomy (LC) is as effective as two-stage endo-laparoscopic treatment, but with shorter hospital stay, lower cost and recurrent stone rate. Aim of this paper was to report the authors' experience with LCBDE during LC.

METHODS

A retrospective analysis of patients who underwent LCBDE for ductal stones was performed. Recurrent stones were defined as CBD stones detected beyond 6 months from the procedure. Postoperative biliary stricture was defined as a symptomatic reduction of CBD diameter.

RESULTS

Out of 3444 patients who underwent LC, 384 (11%) had CBD stones treated by trans-cystic duct exploration [214 (6%) patients, TCD-CBDE] or choledochotomy [170 (5%) patients, C-CBDE]. For TCD-CBDE and C-CBDE, mean operative time was 127 ± 69 and 191 ± 74 min, respectively. Major morbidity rate was 3% (n = 6) in TCD-CBDE and 6% (n = 11) in C-CBDE. The incidence of residual stones was 5% (n = 20) and complete ductal clearance rate was 95% (n = 364). After long-term follow-up (mean 189 ± 105 months) the recurrent stone rate was 2%.

DISCUSSION

In expert centers, LCBDE during LC is safe and effective with low short and long term morbidity rates.

Spontaneously removed biliary stent drainage versus T-tube drainage after laparoscopic common bile duct exploration

Several studies have shown the safety and feasibility of laparoscopic common bile duct exploration (LCBDE) as a minimally invasive treatment options for choledocholithiasis. Use of T-tube or biliary stent drainage tube placement after laparoscopic choledochotomy for common bile duct (CBD) stones is still under debate. This study tried to confirm the safety of spontaneously removable biliary stent in the distal CBD after LCBDE to allow choledochus primary closure. A total of 47 patients with choledocholithiasis underwent LCBDE with primary closure and internal drainage using a spontaneously removable biliary stent drainage tube (stent group, N = 22) or T-tube (T-tube group, N = 25). Operative parameters and outcomes are compared. Surgical time, intraoperative blood loss, length of hospital stay, drainage tube removal time, postoperative intestinal function recovery, and cost of treatment were all significantly lower in the stent group as compared to that in the T-tube group (P < 0.05 for all). Otherwise, Bile leakage between the two groups had no significant difference (P > 0.05). The biliary stent drainage tube was excreted spontaneously 4 to 14 days after surgery with the exception of one case, where endoscopic removal of biliary tube was required due to failure of its spontaneous discharge. LCBDE with primary closure and use of spontaneously removable biliary stent drainage showed advantage over the use of traditional T-tube drainage in patients with choledocholithiasis.

Results of Medium Seventeen Years' Follow-Up after Laparoscopic Choledochotomy for Ductal Stones

Introduction. In a previously published article the authors reported the long-term follow-up results in 138 consecutive patients with gallstones and common bile duct (CBD) stones who underwent laparoscopic transverse choledochotomy (TC) with T-tube biliary drainage and laparoscopic cholecystectomy (LC). Aim of this study is to evaluate the results at up to 23 years of follow-up in the same series. Methods. One hundred twenty-one patients are the object of the present study. Patients were evaluated by clinical visit, blood assay, and abdominal ultrasound. Symptomatic patients underwent cholangio-MRI, followed by endoscopic retrograde cholangiopancreatography (ERCP) as required. Results. Out of 121 patients, 61 elderly patients died from unrelated causes. Fourteen patients were lost to follow-up. In the 46 remaining patients, ductal stone recurrence occurred in one case (2,1%) successfully managed by ERCP with endoscopic sphincterotomy. At a mean follow-up of 17.1 years no other patients showed signs of bile stasis and no patient showed any imaging evidence of CBD stricture at the site of choledochotomy. Conclusions. Laparoscopic transverse choledochotomy with routine T-tube biliary drainage during LC has proven to be safe and effective at up to 23 years of follow-up, with no evidence of CBD stricture when the procedure is performed with a correct technique.

Single-session minimally invasive management of common bile duct stones

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

Use of biliary stent in laparoscopic common bile duct exploration

INTRODUCTION

It is well supported in the literature that laparoscopic common bile duct exploration (LCBDE) for choledocholithiasis has equal efficacy when compared to ERCP followed by laparoscopic cholecystectomy. Decompression after supra-duodenal choledochotomy is common practice as it reduced the risk of bile leaks. We conducted a prospective non-randomized study to compare outcomes and length of stay in patients undergoing biliary stent insertion versus T-tube drainage following LCBDE via choledochotomy.

METHODS AND PROCEDURES

The study involved 116 patients with choledocholithiasis who underwent LCBDE and decompression of the biliary system by either ante-grade biliary stent or T-tube insertion. A 7 French straight/duodenal curve biliary Diagmed™ stent (9-11 cm) was placed in 82 patients (Biliary Stent Group). T-tube insertion was used for 34 patients (T-tube group). The length of hospital stay and complications for the selected patients were recorded. All trans-cystic common bile duct explorations were excluded from the study.

RESULTS

The mean hospital stay for patients who underwent ante-grade biliary stent or T-tube insertion after LBCDE were 1 and 3.4 days, respectively. This is a statistically significant result with a p value of less than 0.001. Of the T-tube group, two patients required laparoscopic washout due to bile leaks, one had ongoing biliary stasis and one reported ongoing pain whilst the T-tube was in situ. A complication rate of 11.2%, this was a significant finding. There were no complications or concerns reported for the Biliary Stent Group.

CONCLUSION

Our results show that there is a significant reduction in length of hospital stay and morbidity for patients that have ante-grade biliary stent decompression of the CBD post laparoscopic choledochotomy when compared T-tube drainage. This implies that ante-grade biliary stent insertion is likely to reduce costs and increase overall patient satisfaction. We support the use of ante-grade biliary stent insertion during LCBDE when primary closure is not preferred.

Technique for the safe placement of a biodegradable stent into the common bile duct of rabbits

Biodegradable common bile duct (CBD) stents are in high clinical demand. Animal experiments concerning the surgical placement of biliary stents made of new materials are being performed more frequently than ever before. However, these animal experiments only use large animals. In this study, a central venous catheterization set was used as a modified stent introducer system in rabbits. A biodegradable Mg-6Zn alloy CBD stent was passed through the duodenal papilla using this stent introducer system. Computed tomography (CT) scanning of the CBD stent in vivo and levels of serum lipase (LPS) were investigated. Twelve rabbits underwent CBD stent insertion and one animal died due to an anesthetic accident. After 3 weeks, when the remaining 11 rabbits were sacrificed, no jaundice or bile leakage was observed. CT scanning of the 11 rabbits suggested that the biodegradable Mg-6Zn stent was successfully placed into the CBD. When the preoperative and postoperative levels of LPS were compared, no statistically significant differences were observed. This new method appears to be feasible and safe for the placement of stents into the CBDs of small animals. This new method can increase the animal number of CBD stent experiment, and improve the quality of experiments.

Does laparoscopic approach impair T-tube-related sinus-tract formation?

PURPOSE

Postoperative morbidity after bile duct exploration with T-tube insertion is mainly related to tube removal and incomplete sinus-tract formation leading to serious complications. Laparoscopic surgery reduces abdominal adhesion formation and diminishes tissue trauma and inflammatory response to surgery, which is essential for sinus-tract formation. This study evaluates if complication rate of T-tube removal is increased after laparoscopic bile duct exploration.

METHODS

Between January 2004 and January 2011, 94 patients underwent a T-tube insertion following choledocolithotomy (44 and 50 patients in the laparoscopic and open surgery group, respectively). Epidemiological data, preoperative characteristics, day of tube removal, and morbidity rates were analyzed.

RESULTS

Global T-tube removal-related biliary complication rate was 14.9% (18.2% in the laparoscopic group vs. 12% in the open surgery group). Although the day of T-tube removal was significantly delayed, there was a slight increased incidence of biliary peritonitis requiring reintervention in the laparoscopic surgery group (6.9% vs. 2%).

CONCLUSIONS

We reveal that T-tube removal is associated with significant morbidity. There was no statistical difference between the laparoscopic and the open surgery group, although global biliary complications after tube removal were slightly increased and bile spillage was worse delimited when T-tube was inserted laparoscopically. Laparoscopic approach may diminish inflammatory response and adherence development and impair, and therefore sinus-tract formation.

Ten-year experience on common bile duct exploration without T-tube insertion

BACKGROUNDS/AIMS

Common bile duct (CBD) exploration has been a procedure necessary to remove stones which are not removable by endoscopic sphincterotomy (EST). T-tube was installed mainly in the concern of bile leakage after procedure. But T-tube itself can only cause bile peritonitis and thus, prolonged discomfort and care after operation. In addition, in the era of laparoscopy, T-tube insertion adds much operation time and is technically difficult for installation during the procedure.

METHODS

Our case of open cholecystectomy and primary closure of CBD not leaving T-tube (n=28, group I) with reports dating from July 1998 to June 2007 is presented here to see whether primary closure without T-tube is safe as compared with T-tube inserted cases performed at the same center (n=15, group II). Operative cholangiography, CT scan, ultrasound and biochemical data were followed up for both groups and surveyed on operative complications as well to determine the outcomes.

RESULTS

Bile leakage in 1, recurrent stone in 2 and obstructive jaundice in 1 were all considered during the follow up period among 28 group I patients (n=6), when compared to T-tube inserted group II patients with 2 bile peritonitis, 1 residual stones and 1 pancreatitis (n=4), showing no meaningful differences (p=0.07).

CONCLUSIONS

CBD exploration and direct primary closure not leaving T-tube is an acceptable operational option as recently tried in many choledochotomies.

Is the end of the T-tube drainage era in laparoscopic choledochotomy for common bile duct stones is coming? A systematic review and meta-analysis

OBJECTIVE

This study aims to compare the efficacy and safety of T-tube free (TTF) versus T-tube drainage (TTD) after laparoscopic common bile duct exploration (LCBDE).

BACKGROUND

LCBDE has been proven to be an effective and preferred treatment approach for uncomplicated choledocholithiasis, and the appropriateness of T-tube placement after laparoscopic choledochotomy for common bile duct (CBD) stones is still under debate.

METHODS

A systematic literature search (PubMed, EMBASE, Science Citation Index, Springer-Link, and Cochrane Central Register of Controlled Trials) was performed. Postoperative complications were evaluated/graded according to the modified Clavien classification. Other variables extracted including primary closures of the CBDs and the associated assistant methods, T-tube types, and placement durations. Stratified and sensitivity analyses were performed both to explore heterogeneity between studies and to assess the effects of the study qualities.

RESULTS

A total of 956 patients from 12 studies were included. The pooled odds ratio for postoperative complications and biliary-specific complications in TTF was found to be 0.59 [95% confidence interval (CI), 0.38-0.91; P = 0.02], 0.62 (95% CI, 0.36-1.06; P = 0.08), respectively, when compared with TTD. Operative time and hospital stay were significantly decreased in the TTF group, with the pooled weighted mean differences being 18.84 minutes (95% CI, -27.01 to 10.67; P < 0.01) and 3.22 days (95% CI, -4.59 to 1.84; P < 0.01), respectively.

CONCLUSIONS

The results of this meta-analysis demonstrate that among patients undergoing laparoscopic choledochotomy for common bile duct stones, primary closure of the CBD alone is superior to TTD; however, there is no significant benefit in terms of primary duct closure with various internal or external drainage techniques. Further randomized controlled trials are eagerly awaited to prove these findings.

A randomized trial comparing the use of endobiliary stent and T-tube for biliary decompression after laparoscopic common bile duct exploration

PURPOSE

To compare the use of a biliary stent with T-tube for biliary decompression after laparoscopic common bile duct (CBD) exploration.

METHODS

Between September 2004 and March 2008, 60 patients undergoing laparoscopic CBD exploration for CBD stones were randomized to choledochotomy closure over either a biliary stent or a T-tube after CBD clearance. Patients at high risk for surgery and unremitting cholangitis requiring preoperative endoscopic biliary drainage were excluded.

RESULTS

There were 29 and 31 patients in the T-tube and stenting groups, respectively. The 2 groups were comparable with respect to their demographic profile and disease characteristics. Patients in the stent group had a significantly shorter operative time and postoperative stay with an earlier return to normal activity (P<0.0001).

CONCLUSIONS

Choledochotomy closure over a stent results in a shorter postoperative stay and an earlier return to normal activity compared with closure over a T-tube without any increase in morbidity.

Laparoscopic common bile duct exploration in patients with previous upper abdominal operations

Backgrounds/Aims

We aimed to to evaluate the feasibility of laparoscopic common bile duct exploration (LCBDE) in patients with previous upper abdominal surgery.

Methods

Retrospective analysis was performed on data from the attempted laparoscopic common bile duct exploration in 44 patients. Among them, 5 patients with previous lower abdominal operation were excluded. 39 patients were divided into two groups according to presence of previous upper abdominal operation; Group A: patients without history of abdominal operation. (n=27), Group B: patients with history of upper abdominal operation. Both groups (n=12) were compared to each other, with respect to clinical characteristics, operation time, postoperative hospital stay, open conversion rate, postoperative complication, duct clearance and mortality.

Results

All of the 39 patients received laparoscopic common bile duct exploration and choledochotomy with T-tube drainage (n=38 [97.4%]) or with primary closure (n=1). These two groups were not statistically different in gender, mean age and presence of co-morbidity, mean operation time (164.5±63.1 min in group A and 134.8±45.2 min in group B, p=0.18) and postoperative hospital stay (12.6±5.7 days in group A and 9.8±2.9 days in group B, p=0.158). Duct clearance and complication rates were comparable (p>0.05). 4 cases were converted to open in group A and 1 case in group B respectively. In group A (4 of 27 (14.8%) and 1 of 12 (8.3%) in group B, p=0.312) Trocar or Veress needle related complication did not occur in either group.

Conclusions

LCBDE appears to be a safe and effective treatment even in the patients with previous upper abdominal operation if performed by experienced laparoscopic surgeon, and it can be the best alternative to failed endoscopic retrograde cholangiopancreatography for difficult cholelithiasis.

Repair of bile duct defect with degradable stent and autologous tissue in a porcine model

AIM: To introduce and evaluate a new method to repair bile duct defect with a degradable stent and autologous tissues.

METHODS: Eight Ba-Ma mini-pigs were used in this study. Experimental models with common bile duct (CBD) defect (0.5-1.0 cm segment of CBD resected) were established and then CBD was reconstructed by duct to duct anastomosis with a novel degradable stent made of poly [sebacic acid-co-(1,3-propanediol)-co-(1,2-propanediol)]. In addition, a vascularized greater omentum was placed around the stent and both ends of CBD. Cholangiography via gall bladder was performed for each pig at postoperative months 1 and 3 to rule out stent translocation and bile duct stricture. Complete blood count was examined pre- and post-operatively to estimate the inflammatory reaction. Liver enzymes and serum bilirubin were examined pre- and post-operatively to evaluate the liver function. Five pigs were sacrificed at month 3 to evaluate the healing of anastomosis. The other three pigs were raised for one year for long-term observation.

RESULTS: All the animals underwent surgery successfully. There was no intraoperative mortality and no bile leakage during the observation period. The white blood cell counts were only slightly increased on day 14 and month 3 postoperatively compared with that before operation, the difference was not statistically significant (P = 0.652). The plasma level of alanine aminotransferase on day 14 and month 3 postoperatively was also not significantly elevated compared with that before operation (P = 0.810). Nevertheless, the plasma level of γ-glutamyl transferase was increased after operation in both groups (P = 0.004), especially 2 wk after operation. The level of serum total bilirubin after operation was not significantly elevated compared with that before operation (P = 0.227), so did the serum direct bilirubin (P = 0.759). By cholangiography via gall bladder, we found that the stent maintained its integrity of shape and was still in situ at month 1, and it disappeared completely at month 3. No severe CBD dilation and stricture were observed at both months 1 and 3. No pig died during the 3-mo postoperative observation period. No sign of necrosis, bile duct stricture, bile leakage or abdominal abscess was found at reoperation at month 3 postoperatively. Pigs had neither fragments of stent nor stones formed in the CBD. Collagen deposit was observed in the anastomosis by hematoxylin and eosin (HE) and Masson’s trichrome stains. No severe cholestasis was observed in liver parenchyma by HE staining. Intestinal obstruction was found in a pig 4 mo after operation, and no bile leakage, bile duct stricture or biliary obstruction were observed in laparotomy. No sign of bile duct stricture or bile leakage was observed in the other two pigs.

CONCLUSION: The novel method for repairing bile duct defect yielded a good short-term effect without postoperative bile duct stricture. However, the long-term effect should be further studied.

Primary closure following laparoscopic common bile duct exploration combined with intraoperative cholangiography and choledochoscopy

BACKGROUND

Laparoscopic common bile duct exploration (LCBDE) has become one of the main options for treating choledocholithiasis associated with cholelithiasis. Our objective was to assess the short-term outcomes of patients undergoing laparoscopic primary closure of the common bile duct (CBD) compared with laparoscopic choledochotomy plus T-tube drainage.

METHODS

We retrospectively studied 137 patients undergoing primary closure following LCBDE (group A) compared with 102 cases with laparoscopic choledochotomy plus T-tube drainage (group B) between January 2007 and January 2010. Intraoperative cholangiography (IOC) and choledochoscopy were performed in all patients.

RESULTS

Three patients in group A (2.2%) were converted to open surgery and two (2.0%) in group B because of serious adherence. According to routine IOC, unexpected CBD stones were found in 16 cases (6.8%). The duration of the operation in group A was shorter than in group B (92.4 ± 15.2 vs. 125.7± 32.6 min, P < 0.05), as was length of postoperative stay (3.1± 2.4 vs. 5.7± 4.3 days, P < 0.05). Postoperative bile leakage occurred in six patients (4.5%) in group A and four cases (4.0%) in group B; all of the patients recovered after simple drainage without reoperation. Bile peritonitis was seen in one case after T-tube removal. The median follow-up was 26 months. There were no recurrences.

CONCLUSIONS

Laparoscopic primary closure of the CBD is safe and successful for the management of CBD stones. Application of IOC and choledochoscopy to ensure clearance of the CBD and careful suturing are essential for primary closure.

Antegrade common bile duct (CBD) stenting after laparoscopic CBD exploration

Laparoscopic common bile duct exploration (LCBDE) has been found to be a safe, efficient and cost-effective treatment for choledocholithiasis. Following LCBDE, the clearance may be ascertained by a cholangiogram or choledochoscopy. The common bile duct (CBD) may be closed primarily with or without a stent in situ or may be drained by means of a T-tube or a biliary enteric anastomosis.

The fading role of T-tube in laparoscopic choledochotomy: primary choledochorrhaphy and over pigtail j and endonasobiliary drainage tubes

BACKGROUND AND AIM

The traditional management of open/laparoscopic choledochotomy after common bile duct (CBD) exploration is accomplished by placement of a T-tube, a procedure historically associated with complications and discomfort. In this study, we share in humble our laparoscopic experience of the use of primary closure of CBD, primary closure over pigtail J, and endonasobiliary drainage (ENBD) tubes as easy and effective alternatives to T-tubes.

METHODS

From April 2006 to March 2009, 27 (16 women) patients with CBD stones underwent laparoscopic choledochotomy at our institute and were engaged in this study by means of T-tube-free approach after bile duct exploration: primary closure, pigtail J tube, and ENBD tube groups. On admission, routine laboratory and imaging workups were performed to confirm choledocholithiasis diagnosis.

RESULTS

The mean operative time for primary closure, pigtail J tube, and ENBD tube groups were 95, 100, and 97.5 minutes, respectively. There was no conversion to open surgery nor was intraoperative complication experienced in all the groups. No major biliary complications such as bile leakage or bile peritonitis were seen; however, 1 patient from the pigtail J group experienced premature tube dislodgement and 1 patient from the ENBD tube group was found with a singular CBD retained stone.

CONCLUSIONS

Laparoscopic primary closure of the CBD and over pigtail J and ENBD tubes are easy and effective alternatives to T-tube placements; these procedures are safe and with great feasibility, they offer faster recovery time for patients and early discharge with lower hospital charge.

Is the use of T-tube necessary after laparoscopic choledochotomy?

BACKGROUND

Traditionally, the common bile duct (CBD) is closed with T-tube drainage after choledochotomy and removal of CBD stones. However, the insertion of a T-tube is not without complication.

AIM OF WORK

This randomized study was designed to compare the use of T-tube and primary closure of choledochotomy after laparoscopic choledochotomy to determine whether primary closure can be as safe as closure with T-tube drainage.

METHODS

Between February 2006 and June 2009, 122 consecutive patients with proven choledocholithiasis had laparoscopic choledochotomy. They were randomized into two equal groups: T-tube (n = 61) and primary closure (n = 61). Demographic data, intraoperative findings, postoperative complications, and postoperative stay were recorded.

RESULTS

There was no mortality in both groups. There were no differences in the demographic characteristics or clinical presentations between the two groups. Compared with the T-tube group, the operative time and postoperative stay were significantly shorter and the incidences of overall postoperative complications and biliary complications were statistically and significantly lower in the primary closure group.

CONCLUSION

Laparoscopic common bile duct exploration with primary closure without external drainage after laparoscopic choledochotomy is feasible, safe, and cost-effective. After verification of ductal clearance, the CBD could be closed primarily without T-tube insertion.

Feasibility of biodegradable PLGA common bile duct stents: an in vitro and in vivo study

The current study investigates the feasibility of using a biodegradable polymeric stent in common bile duct (CBD) repair and reconstruction. Here, poly(L-lactide-co-glycolide) (PLGA, molar ratio LA/GA = 80/20) was processed into a circular tube- and dumbbell-shaped specimens to determine the in vitro degradation behavior in bile. The morphology, weight loss, and molecular weight changes were then investigated in conjunction with evaluations of the mechanical properties of the specimen. Circular tube-shaped PLGA stents with X-ray opacity were subsequently used in common bile duct exploration (CBDE) and primary suturing in canine models. Next, X-ray images of CBD stents in vivo were compared and levels of serum liver enzymes and a histological analysis were conducted after stent transplantation. The results showed that the PLGA stents exhibited the required biomedical properties and spontaneously disappeared from CBDs in 4-5 weeks. The degradation period and function match the requirements in repair and reconstruction of CBDs to support the duct, guide bile drainage, and reduce T-tube-related complications.

Is a T-tube necessary after common bile duct exploration?

BACKGROUND

T-tube drainage used to be standard practice after surgical choledocholithotomy, but there is now a tendency in some centers to close the common bile duct (CBD) primarily. This study was designed to review the complications associated with T-tube drainage after CBD exploration and to determine whether primary closure of the bile duct reduces postoperative morbidity.

METHODS

A retrospective audit was performed on patients undergoing CBD exploration between July 1997 and March 2007, who were identified from the theatre database of one teaching hospital. Intraoperative findings and postoperative complications were recorded from the clinical notes.

RESULTS

During the study period, 158 patients (97 women; median age 65 (range, 25-90) years) underwent CBD exploration. A T-tube was inserted in 91 patients (group I) and the CBD was closed primarily in 67 (group II). One or more biliary complications occurred in 26 patients (16.5%): 20 (22.0%) in group I and 6 (8.9%) in group II (p = 0.03). In group I, 15 had a biliary leak (3 needed reoperation), 2 had accidental slippage of the tube, 2 an entrapped T-tube, and 1 a retained stone. In group II, six patients had biliary leakage, two of whom were re-explored. Six patients in group I also had peritubal infection, necessitating the use of antibiotics. There were three deaths: two in group I (1 T-tube-related) and 1 in group II (p = 1, not significant).

CONCLUSION

There is a lower biliary complication rate associated with primary closure of the CBD than after T-tube drainage.

[Single-stage management of common duct stones by video-assisted laparoscopy. Analysis of 10 years' experience]

INTRODUCTION

The management of patients with gallstone disease and ductal calculi is controversial. The main options are one-stage or two-stage management.

MATERIAL AND METHOD

We performed a retrospective analysis of the experience gained over 10 years in the one-stage management of common duct stones in a high-volume tertiary hospital.

RESULTS

A total of 569 patients were initially treated by laparoscopy. Of these, 412 (76.3%) underwent the transcystic approach, 128 (23.7%) underwent laparoscopic choledochotomy and 29 (5%) were converted to open surgery. Overall morbidity and mortality were 2.46% and 0.52%, respectively.

CONCLUSIONS

In high-volume centers, one-stage laparoscopic management of common duct stones is safe and feasible, with a high proportion of patients that only require a transcystic approach.

Trend towards primary closure following laparoscopic exploration of the common bile duct

INTRODUCTION

The aim of this study was the assessment of patient outcome, peri-operative complications, length of stay and duration of operation after laparoscopic primary closure of the common bile duct (CBD) compared with choledochotomy with T-tube drainage and trans-cystic exploration.

PATIENTS AND METHODS

Analysis of prospectively collected data on 71 explorations of the common bile duct between July 2001 and March 2006.

RESULTS

A total of 71 patients had exploration of the CBD. Within this group, 12 were referred after failed endoscopic retro-grade cholangiopancreatography (ERCP). The methods of exploration included trans-cystic (9 cases), choledochotomy with T-tube (12), and choledochotomy with primary closure (50). CBD stones were found in 66 patients. In the remaining cases, we found a stricture in 1, debris in 2, and dilatation of the CBD without a stone in 2. There were 5 conversions to open technique and 3 patients required postoperative ERCP (1 with permanent stenting). Peri-operative complications included T-tube (3), primary closure group (9), and trans-cystic (0). There was no statistical significant difference (Chi-square test, P = 0.296) between the groups. There was a trend towards a shorter length of stay in the primary closure group as compared with the trans-cystic and T-tube groups of 4.16, 4.44, and 6.33 days, respectively. However, it did not reach statistical significance (one-way analysis of variance with Boneferroni correction, mean difference between groups 1.89, 0.28, 2,17, statistical significance at P < 0.05). The shortest operating time was in the primary closure group (95.92 min) which was statistically significant (P < 0.001). We did not use a biliary drain in the last 48 patients.

CONCLUSIONS

Primary laparoscopic closure of the CBD is safe and results in a reduction in operating time. Choledochoscopy ensures clearance of the CBD and eliminates the need for T-tube.

Laparoscopic primary choledochorrhaphy over endonasobiliary drainage tubes

BACKGROUND

The T-tube is widely used in laparoscopic choledochotomy to decompress the biliary tree. However, there are high morbidity rates related to the T-tube. This study reviewed the results of laparoscopic primary choledochorrhaphy over endonasobiliary drainage (ENBD) tubes to find an effective alternative to the T-tube for the performance of laparoscopic choledochotomy.

METHODS

From March 2003 to September 2005, 23 patients (9 men and 14 women) with choledocholithiasis underwent laparoscopic choledochotomy over ENBD tubes. The mean age of these patients was 47 years (range, 32-73 years). At admission, six patients had cholangitis. All the patients had ENBD tubes placed preoperatively after the failure of endoscopic sphincterotomy.

RESULTS

There was no conversion to open surgery. The mean operative time was 90 min (range, 70-150 min). There were no biliary complications such as bile leaks, biliary peritonitis, or pancreatitis. No residual stones were found by postoperative cholangiograms. The ENBD tubes were removed between postoperative days 7 and 9. The hospital stay ranged from 8 to 14 days, with 16 patients (70%) discharged on postoperative day 8. The complications were limited to one umbilical infection and one case of pneumonia. The median follow-up period was 24 months (range, 8-36 months), and none of the patients were readmitted with biliary symptoms.

CONCLUSION

Laparoscopic choledochotomy over ENBD tubes proved to be technically feasible and safe. The ENBD tube decompresses the biliary tree and allows for cholangiography after surgery. Its removal does not need to wait for tract maturation, which allows an earlier removal of the tube and a shorter postoperative hospital stay. Laparoscopic choledochotomy over ENBD tubes is an effective alternative to the T-tube in laparoscopic choledochotomy.

Cost-effective method for laparoscopic choledochotomy

BACKGROUND

Recent reports have noted that postoperative complications following open or laparoscopic choledochotomy for common bile duct (CBD) exploration are mainly related to the T-tube presence, and that there has been no trend of decrease in the laparoscopic era. Laparoscopic endobiliary stent placement with primary closure of the CBD has been proposed as a safe and effective alternative to T-tube placement.

METHODS

Between January 1999 and January 2003, 53 consecutive patients suffering from proven choledocholithiasis underwent laparoscopic common bile exploration (LCBDE) via choledochotomy. In the early period, a T-tube was placed at the end of the procedure (group A, n = 32) while, from June 2001 onwards, laparoscopic biliary stent placement and primary CBD closure were chosen as the drainage method (group B, n = 21).

RESULTS

Six patients developed T-tube-related complications postoperatively. Univariate analysis revealed statistically significant lower morbidity rate and shorter postoperative hospital stay for the stent group. Although not statistically significant, a median saving of 780 UK pounds per patient was observed in the stent group.

CONCLUSION

Biliary endoprosthesis placement following laparoscopic choledochotomy avoids the well-known complications of a T-tube, leading to a shorter postoperative hospital stay. The method is safe and effective and it should also be considered as cost-effective compared to T-tube placement. Further studies are required in order to document cost-effectiveness of the method.

Long-term results after laparoscopic transverse choledochotomy for common bile duct stones

BACKGROUND

The aim of this study was to evaluate the long-term results of laparoscopic transverse choledochotomy (TC) during laparoscopic cholecystectomy (LC).

METHODS

Ductal stones were present in 344 of 3,212 patients (10.7%) who underwent LC. The procedure was completed laparoscopically in 329 cases (95.6%), with a TC in 138 cases (41.9%) (the subjects of this study), and with a transcystic duct approach in 191 cases (58.1%).

RESULTS

Biliary drainage was used in 131 of 138 cases (94.9%). There were major complications in eight patients (5.7%), and one patient died (0.7%). Retained stones were seen in 11 cases (8%). None of the patients was lost to follow-up (mean, 72.3 months; range, 11-145). Ductal stones recurred in five patients (3.6%). No signs of bile stasis and no biliary strictures were observed. In all, 121 patients are alive with no biliary symptoms; 16 have died from unrelated causes.

CONCLUSION

Long-term follow-up after laparoscopic TC during LC proved its safety and efficacy.

Advantages of laparoscopic stented choledochorrhaphy over T-tube placement

Background

Postoperative complications after laparoscopic choledochotomy are mainly related to the T tube. Both laparoscopic endobiliary stent placement with primary closure of the common bile duct (CBD) and primary closure of the CBD without drainage have been proposed as safe and effective alternatives to T-tube placement.

Methods

This was a retrospective analysis of data collected prospectively on 53 consecutive patients suffering from proven choledocholithiasis who underwent laparoscopic CBD exploration through a choledochotomy between January 1999 and January 2003. In the early period a T-tube was placed at the end of the procedure (n = 32). Biliary stent placement and primary CBD closure was performed from June 2001 (n = 21).

Results

There were no significant differences in epidemiological characteristics, preoperative factors or intraoperative findings between the groups. Seven patients developed complications, six in the T-tube group and one in the stent group. Univariate analysis revealed a significantly lower morbidity rate and shorter postoperative hospital stay in the stent group.

Conclusion

Placement of a biliary endoprosthesis after laparoscopic choledochotomy achieves biliary decompression, and avoids the complications of a T tube, leading to a shorter postoperative hospital stay. The method is a safe and effective alternative method of CBD drainage after laparoscopic choledochotomy.
