Clinical efficacy of laparoscopic cholecystectomy combined with endoscopic papillary balloon dilation in treatment of gallbladder stones with common bile duct stones: A retrospective study

BACKGROUND The incidence of cholelithiasis has been on the rise in recent years,but the choice of procedure is controversial.AIM To investigate the efficacy of laparoscopic cholecystectomy(LC)combined with endoscopic papillary balloon dilation(EPBD)in patients with gallbladder stones(GS)with common bile duct stones(CBDS).METHODS The clinical data of 102 patients with GS combined with CBDS were selected for retrospective analysis and divided into either an LC+EPBD group(n=50)or an LC+endoscopic sphincterotomy(EST)group(n=52)according to surgical methods.Surgery-related indexes,postoperative recovery,postoperative complications,and expression levels of inflammatory response indexes were compared between the two groups.RESULTS Total surgical time,stone free rate,rate of conversion to laparotomy,and successful stone extraction rate did not differ significantly between the LC+EPBD group and LC+EST group.Intraoperative hemorrhage,time to ambulation,and length of hospitalization in the LC+EPBD group were lower than those of the LC+EST group(P<0.05).The rate of total complications of the two groups was 9.80%and 17.65%,respectively,and the difference was not statistically significant.No serious complications occurred in either group.At 48 h postoperatively,the expression levels of interleukin-6,tumor necrosis factor-α,high-sensitivity Creactive protein,and procalcitonin were lower in the LC+EPBD group than in the LC+EST group(P<0.05).At 3 d postoperatively,the expression levels of aspartate transaminase,alanine transaminase,and total bilirubin were lower in the LC+EPBD group than in the LC+EST group(P<0.05).CONCLUSION LC combined with EPBD and LC combined with EST are both effective procedures for the treatment of GS with CBDS,in which LC combined with EPBD is beneficial to shorten the patient’s hospitalization time,reduce the magnitude of elevated inflammatory response indexes,and promote postoperative recovery.

Reappraisal of endoscopic papillary balloon dilation for the management of common bile duct stones

Although endoscopic sphincterotomy(EST) is still considered as a gold standard treatment for common bile duct(CBD) stones in western guideline, endoscopic papillary balloon dilation(EPBD) is commonly used by the endoscopists in Asia as the first-line treatment for CBD stones. Besides the advantages of a technical easy procedure, endoscopic papillary large balloon dilation(EPLBD) can facilitate the removal of large CBD stones.The indication of EPBD is now extended from removal of the small stones by using traditional balloon, to removal of large stones and avoidance of lithotripsy by using large balloon alone or after EST. According to the reports of antegrade papillary balloon dilatation, balloon dilation itself is not the cause of pancreatitis. On the contrary, adequate dilation of papillary orifice can reduce the trauma to the papilla and pancreas by the basket or lithotripter during the procedure of stone extraction. EPLBD alone is as effective as EPLBD with limited EST. Longer ballooning time may be beneficial in EPLBD alone to achieve adequate loosening of papillary orifice. The longer ballooning time does not increase the risk of pancreatitis but may reduce the bleeding episodes in patients with coagulopathy. Slowly inflation of the balloon, but not exceed the diameter of bile duct and tolerance of the patients are important to prevent the complication of perforation. EPBLD alone or with EST are not the sphincter preserved procedures, regular follow up is necessary for early detection and management of CBD stones recurrence.

Endoscopic papillary large balloon dilation alone or combined with small or complete sphincterotomy for the removal of large common bile duct stones

Background:Endoscopic papillary large balloon dilation(EPLBD)has been proposed as an alternative to manage large bile duct stones.However,EPLBD alone or combined with sphincterotomy remains controversial.Methods:Between Jan.2014 and Dec.2017,195 consecutive patients with proven large common bile duct stones(size≥10 mm)were retrospectively analyzed.We compared the baseline characteristics,procedure time,success rate of stone removal and morbidity outcomes in different groups.Results:There were no significant difference between baseline characteristics of the groups compared.A total of 89.2%,95.4%,and 93.8% of the patients in the EPLBD,EPLBD+small sphincterotomy(SES),and EPLBD+complete sphincterotomy(CES)groups had stones cleared(P=0.473),respectively.There was no difference in terms of procedure time(33.5±10.2,34.8±9.0,34.9±8.2,in the EPLBD,EPLBD+SES,and EPLBD+CES groups,respectively).However,when assigned to tvvo groups according to bile duct stones diameter(bile duct stones<13 mm,bile duct stones≥13 mm).in the bile duct stones<13 mm group,the procedure time was significantly less in the EPLBD group than the EPLBD+SES group and the EPLBD+CES group(P=0.028).In the bile duct stones≥13 mm group,the mechanical lithotripsy rate of EPLBD was significantly higher compared to EPLBD+SES or EPLBD+CES(P=0.032).The complication rates were similar among all groups.Conclusions:The diameter of bile duct stones should be taken into consideration when choosing EPLBD alone or combined with small sphincterotomy for the removal of common bile duct stones.

Endoscopic papillary large balloon dilation for the removal of bile duct stones

Endoscopic papillary large balloon dilation(EPLBD)with endoscopic sphincterotomy(EST)has been widely used as the alternative to EST along with endoscopic mechanical lithotripsy(EML)for the removal of large or difficult bile duct stones.Furthermore,EPLBD without EST was recently introduced as its simplified alternative technique.Thus,we systematically searched PubMed,Medline,the Cochrane Library and EMBASE,and analyzed all gathered data of EPLBD with and without EST,respectively,by using a single standardized definition,reviewing relevant literatures,published between 2003and June 2013,where it was performed with largediameter balloons(12-20 mm).The outcomes,including the initial success rate,the rate of needs for EML,and the overall success rate,and adverse events were assessed in each and compared between both of two procedures:"EPLBD with EST"and"EPLBD without EST".A total of 2511 procedures from 30 published articles were included in EPLBD with EST,while a total of413 procedures from 3 published articles were included in EPLBD without EST.In the results of outcomes,the overall success rate was 96.5%in EPLBD with EST and97.2%in EPLBD without EST,showing no significant difference between both of them.The initial success rate(84.0%vs 76.2%,P<0.001)and the success rate of EPLBD without EML(83.2%vs 76.7%,P=0.001)was significantly higher,while the rate of use of EML was significantly lower(14.1%vs 21.6%,P<0.001),in EPLBD with EST.The rate of overall adverse events,pancreatitis,bleeding,perforation,other adverse events,surgery for adverse events,and fatal adverse events were 8.3%,2.4%,3.6%,0.6%,1.7%,0.2%and 0.2%in EPLBD with EST and 7.0%,3.9%,1.9%,0.5%,0.7%,0%and 0%in EPLBD without EST,respectively,showing no significant difference between both of them.In conclusion,recent accumulated results of EPLBD with or even without EST suggest that it is a safe and effective procedure for the removal of large or difficult bile duct stones without any additional risk of severe adverse events,when performed under appropriate guidelines.

Endoscopic papillary large balloon dilation vs endoscopic sphincterotomy for retrieval of common bile duct stones:A meta-analysis

AIM: To compare the efficacy and safety of endoscopic papillary large balloon dilation (EPLBD) with endoscopic sphincterotomy (EST) in retrieval of common bile duct stones (&#x02265; 10 mm).

Efficacy and safety of endoscopic papillary balloon dilation for the removal of bile duct stones: Data from a “real-life” multicenter study on Dilation-Assisted Stone Extraction

AIM To report data on Dilation-Assisted Stone Extraction(DASE) use in clinical practice and its efficacy and safety trough three Italian referral centers for biliopancreatic diseases treatment. METHODS From January 2011 to December 2015 we collected data on 120 patients treated with DASE. Technical success was obtained when the endoscopist was able to place the balloon trough the papilla inflating the balloon until the final diameter for an adequate time(at least 30 s). Clinical success was obtained after complete stone removal(no remaining stones were visible at the cholangiogram).RESULTS Forty-nine male(40.8%) and 71 female(59%) were enrolled. The mean age was 67.8 years ± 15.7. The mean common bile duct(CBD) dilation was 19.2 mm± 3.9 and the mean size of stones 15.8 ± 2.9. DASE was applied as first approach in 38%(62% after initial failure of stones extraction). Technical and clinical success was of 91% and 87% respectively. In those in which DASE failed alternative treatment were adopted. After DASE 18% of patients experienced a complication(bleeding 9%, pancreatitis 8%, perforation 0.8%). At univariable analysis, elective endoscopic retrograde cholangiopancreatography(P = 0.031), DASE as first approach(P = 0.032), and cannulation of major papilla followed by guidewire insertion(P = 0.004) were related to low risk of complications. Pre-cut was related to an increased risk of complications(P = 0.01). CONCLUSION DASE allowed a higher first-session success rate and can be consider a valid alternative to endoscopic sphincterotomy not only for bigger CBD stones.

Innovation of endoscopic management in difficult common bile duct stone in the era of laparoscopic surgery

Common bile duct(CBD)stone is a common biliary problem,which often requires endoscopic approach as the initial treatment option.Roughly,7%-12%of the subjects who experience cholecystectomy were subsequently referred to biliary endoscopist for further management.In general,there are three classifications of difficult CBD stone,which are based on the characteristics of the stone(larger than 15 mm,barrel or square-shaped stones,and hard consistency),accessibility to papilla related to anatomical variations,and other clinical conditions or comorbidities of the patients.Currently,endoscopic papillary large balloon dilation(EPLBD)of a previous sphincterotomy and EPLBD combined with limited sphincterotomy performed on the same session is still recommended by the European Society of Gastrointestinal Endoscopy as the main approach in difficult CBD stones with history of failed sphincterotomy and balloon and/or basket attempts.If failed extraction is still encountered,mechanical lithotripsy or cholangioscopy-assisted lithotripsy or extracorporeal shockwave lithotripsy can be considered.Surgical approach can be considered when stone extraction is still failed or the facilities to perform lithotripsy are not available.To our knowledge,conflicting evidence are still found from previous studies related to the comparison between endoscopic and surgical approaches.The availability of experienced operator and resources needs to be considered in creating individualized treatment strategies for managing difficult biliary stones.

Biliary drainage of the common bile duct with an enteral metal stent

In this case report we present an elderly patient who was referred to our hospital with recurrent episodes of cholangitis that persisted after placement of fi ve metal stents for a distal common bile duct(CBD) stenosis.All metal stents were endoscopically removed from the CBD by forceps after balloon dilatation of the papilla.A profoundly dilated CBD with sludge and concrements was seen.To ensure adequate bile drainage an enteral metal stent was inserted in the CBD.This case shows that proximally migrated uncovered metal stents in the CBD can be safely removed endoscopically under certain circumstances.We suggest that in the case of a CBD drainage problem due to an extremely dilated CBD,placement of an enteral metal stent in the CBD could be considered,especially in patients who are unfi t for surgery.

Safety and efficacy of percutaneous transhepatic balloon dilation in removing common bile duct stones:A systematic review

BACKGROUND Endoscopic sphincterotomy(EST) is widely regarded as the first choice in the management of common bile duct(CBD) stones. However, for some patients, this treatment is not possible. The percutaneous transhepatic balloon dilation(PTBD)technique has been suggested as an alternative but has yet to gain wide acceptance.AIM To review cases of PTBD for removing CBD stones and explore the safety and efficacy of this treatment.METHODS We conducted a systematic review using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We searched EMBASE,PubMed, and Web of Science for cases of PTBD that underwent CBD stone removal from 1981 to January 2019. We analyzed all relevant articles available in full text. We extracted data on patient's age, gender, overall technique success rate, reasons for technique failure, and the presence and type of major and minor complications. We analyzed the data and reported the results in a table and text.Altogether, we retrieved 12 case series and 6 case reports, for a total of 1347 patients. Thirty cases were excluded due to a lack of patient data.RESULTS The overall technique success rate for removing a CBD stone was 98.5%(1327/1347) and 98.1%(109/111) for removing concurrent CBD and gallbladder stones. Based on available data(n = 1312), mean age of all patients(687 males and625 females) was 68.9 years. The total number of procedures in the remaining 1317 patients(after exclusion) was 3237(average 2.4 procedures per patient). The total number of failures for eliminating a CBD stone was 20, and the reasons for failure included: Stone impaction(n = 10), intrahepatic bile duct stricture(n = 5),large stone(n = 2), severe CBD dilation(n = 1), multiple stones(n = 1), and duodenal perforation(n = 1). Various major complications related to the procedure were reported, but the incidence rate was low(1.4%). No pancreatitis or procedure related mortality was reported. Minor complications including transient hyperamylasemia, nausea, vomiting, abdominal pain, fever, and mild hemobilia were reported. For 218 patients(88 patients with unsuccessful endoscopic removal due to anatomical change and large or impacted stone and130 cases who refused endoscopic procedure due to poor general condition or other additional disease), the CBD stones were successfully pushed into the duodenum by performing the PTBD procedure.CONCLUSION PTBD is a safe and effective approach in the nonoperative management of CBD stones. PTBD provides an alternative treatment when endoscopic procedures fail or are unsuitable for the patient.

Gossypibomas as a rare cause of common bile duct dilation

Gossypibomas are any foreign bodies left inside the patient after an operation. It represents a diagnostic challenge in clinical practice because the clinical consequence may manifest in different forms immediately, months, or even years after the surgical procedure.

Cystic Enlargement of the Bile Duct: Case Report and Review of Literature

Congenital cystic dilatations of the bile duct are rare malformations representing 1 per 13,000 births with a female predominance. Diagnosis of this pathology is based on radiological imaging especially radiological investigations conducted on an ultrasound coupled with Computed tomography (CT) scan and especially a bili-MRI which allows the analysis of the bile duct malformations and the anomalies of the pancreaticobiliary junction. We will discuss in this clinical case the various radiological aspects of cystic dilatations of the biliary duct.

Comprehensive review on small common bile duct stones

Common bile duct stones are among the most common conditions encountered by endoscopists.Therefore,it is well researched;however,some items,such as indications for endoscopic papillary balloon dilatation(EPBD),safety of EPBD and endoscopic sphincterotomy in patients receiving dual antiplatelet therapy or direct oral anticoagulant,selection strategy for retrieval balloons and baskets,lack adequate evidence.Therefore,the guidelines have been updated with new research,while others remain unchanged due to weak evidence.In this review,we comprehensively summarize the standard methods in guidelines and new findings from recent studies on papillary dilation,stone retrieval devices,difficult-to-treat cases,troubleshooting during the procedure,and complicated cases of cholangitis,cholecystolithiasis,or distal biliary stricture.

Ampulla dilation with different sized balloons to remove common bile duct stones

AIM:To assess the outcomes of ampulla dilation with different sized balloons to remove common bile duct (CBD) stones.METHODS:Patients (n=208) were divided into five groups based on the largest CBD stone size of < 5,6-8,8-12,12-14,and > 14 mm.Patients underwent limited endoscopic sphincterotomy (EST) alone or limited EST followed by endoscopic papillary balloon dilation with 8,10,12 and 14 mm balloons,such that the size of each balloon did not exceed the size of the CBD.Short-and long-term outcomes,such as post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis,perforation,bleeding,and pneumobilia were compared among the five groups.RESULTS:The overall rate of successful stone removal in all groups was 100%,and all patients were cured.Eight (3.85%) patients had post-ERCP pancreatitis,none had perforations,and 6 (2.9%) had bleeding re-quiring transfusion.There were no significant differences in early complication rates among the five groups.We observed significant correlations between increased balloon size and the short-and long-term rates of postERCP pneumobilia.Post-ERCP pancreatitis and bleeding correlated significantly with age,with post-ERCP pancreatitis occurring more frequently in patients aged < 60 years,and bleeding occurring more frequently in patients aged > 70 years.We observed a significant correlation between patient age and the diameter of the largest CBD stone,with stones > 12 mm occurring more frequently in patients > 60 years old.CONCLUSION:Choosing a balloon size based on the largest stone diameter is safe and effective for removing CBD stones.Balloon size should not exceed 15 mm.

Endoscopic management of difficult common bile duct stones:Where are we now?A comprehensive review

Endoscopic management for difficult common bile duct(CBD)stones still presents a challenge for several reasons,including anatomic anomalies,patients’individual conditions and stone features.In recent years,variable methods have emerged that have attributed to higher stone removal success rates,reduced cost and lower adverse events.In this review,we outline a stepwise approach in CBD stone management.As first line therapy,endoscopic sphincterotomy and large balloon dilation are recommended,due to a 30%-50%reduction of the use of mechanical lithotripsy.On the other hand,cholangioscopy-assisted lithotripsy has been increasingly reported as an effective and safe alternative technique to mechanical lithotripsy but remains to be reserved in special settings due to limited large-scale evidence.As discussed,findings suggest that management needs to be tailored to the patient’s characteristics and anatomical conditions.Furthermore,we evaluate the management of CBD stones in various surgical altered anatomy(Billroth II,Roux-en-Y and Roux-en-Y gastric bypass).Moreover,we could conclude that cholangioscopy-assisted lithotripsy needs to be evaluated for primary use,rather than following a failed management option.In addition,we discuss the importance of dissecting other techniques,such as the primary use of interventional endoscopic ultrasound for the management of CBD stones when other techniques have failed.In conclusion,we recognize that endoscopic sphincterotomy and large balloon dilation,mechanical lithotripsy and intraductal lithotripsy substantiate an indication to the management of difficult CBD stones,but emerging techniques are in rapid evolution with encouraging results.

Long-term outcomes of endoscopic papillary balloon dilation for removal of bile duct stones in Billroth Ⅱ gastrectomy patients

Background： Endoscopic papillary balloon dilation （EPBD） for common bile duct （CBD） stones removal in Billroth II gastrectomy patients is feasible. However, the long-term outcomes of this technique are notclear. The aim of this study was to evaluate the procedural and long-term outcomes of EPBD for removal of CBD stones in Billroth II gastrectomy patients.

Endoscopic treatment of difficult extrahepatic bile duct stones, EPBD or EST: An anatomic view

Large bile duct stone(> 10 mm) or multiple stones(≥ 3) are challenging for endoscopists. Endoscopic sphincterotomy(EST) is a routine therapeutic endoscopic retrograde cholangiopancreatography(ERCP) procedure usually used. It is safe and effective, but severe perforation or massive bleeding are the main causes of mortality. Because of the permanent destroy ofOddi sphincter, the use of EST is still controversial. Endoscopic papillary balloon dilation(EPBD) gives another way to open the sphincter. Less incidence of bleeding, perforation and partly preserving the Oddi sphincter's function are the main advantages. But high incidence of post-ERCP pancreatitis becomes a predominant problem. According to the anatomical feature of Oddi sphincter, limited EST + EPBD seems a more reasonable procedure. Compared to the former two procedures, it makes the stone extraction process much easier with lower incidences of short-term and long-term complications.

Endoscopic papillary balloon dilation:Revival of the old technique

Radiologists first described the removal of bile duct stones using balloon dilation in the early 1980s.Recently,there has been renewed interest in endoscopic balloon dilation with a small balloon to avoid the complications of endoscopic sphincterotomy(EST)in young patients undergoing laparoscopic cholecystectomy.However,there is a disparity in using endoscopic balloon papillary dilation(EPBD)between the East and the West,depending on the origin of the studies.In the early 2000s,EST followed by endoscopic balloon dilation with a large balloon was introduced to treat large or difficult biliary stones.Endoscopic balloon dilation with a large balloon has generally been recognized as an effective and safe method,unlike EPBD.However,fatal complications have occurred in patients with endoscopic papillary large balloon dilation(EPLBD).The safety of endoscopic balloon dilation is still a debatable issue.Moreover,guidelines of indications and techniques have not been established in performing endoscopic balloon dilation with a small balloon or a large balloon.In this article,we discuss the issue of conventional and large balloon endoscopic dilation.We also suggest the indications and optimal techniques of EPBD and EPLBD.

Endoscopic ultrasound in common bile duct dilatation with normal liver enzymes

In recent years,the description of isolated bile duct dilatation has been increasingly observed in subjects with normal liver function tests and nonspecific abdominal symptoms,probably due to the widespread use of high-resolution imaging techniques.However,there is scant literature about the evolution of this condition and the impact of endoscopic ultrasound(EUS)in the diagnostic work up.When noninvasive imaging tests(transabdominal ultrasound,computed tomography or magnetic resonance cholangiopancreatography)fail to identify the cause of dilatation and clinical or biochemical alarm signs are absent,the probability of having biliary disease is considered low.In this setting,using EUS,the presence of pathologic findings(choledocholithiasis,strictures,chronic pancreatitis,ampullary or pancreatic tumors,cholangiocarcinoma),not always with a benign course,has been observed.The aim of this review has been to evaluate the prevalence of disease among nonjaundiced patients without signs of cytolysis and/or cholestasis and the assessment of EUS yield.Data point out to a promising role of EUS in the identification of a potential biliary pathology.EUS is a low invasive technique,with high accuracy,that could play a double cost-effective role:identifying pathologic conditions with dismal prognosis,in asymptomatic patients with negative prior imaging tests,and excluding pathologic conditions and further follow-up in healthy subjects.

Common Bile Duct Cysts Leading to Cholestasis and Jaundice: A Rare Case Report

Cystic dilatation of the common bile duct constitutes a rare congenital malformation prevalent in people of Asian origin with a female predominance. Its classification follows that of Todani. The commonest form, found in 80% of cases, is type I. Common bile duct cysts are often diagnosed in 2 out of 3 cases, during childhood with adult forms often rare. We hereby report the case of a cystic dilatation of the bile duct in a 75-year-old patient without significant history of disease.

Endoscopic papillary balloon intermittent dilatation and endoscopic sphincterotomy for bile duct stones

AIM: To compare the effectiveness and safety of endoscopic papillary balloon intermittent dilatation (EPBID) and endoscopic sphincterotomy (EST) in the treatment of common bile duct stones. METHODS: From March 2011 to May 2012, endoscopic retrograde cholangiopancreatography was performed in 560 patients, 262 with common bile duct stones. A total of 206 patients with common bile duct stones were enrolled in the study and randomized to receive either EPBID with a 10-12 mm dilated balloon or EST (103 patients in each group). For both groups a conventional reticular basket or balloon was used to remove the stones. After the procedure, routine endoscopic nasobiliary drainage was performed. RESULTS: First-time stone removal was successfully performed in 94 patients in the EPBID group (91.3%) and 75 patients in the EST group (72.8%). There was no statistically significant difference in terms of operation time between the two groups. The overall incidence of early complications in the EPBID and EST groups was 2.9% and 13.6%, respectively, with no deaths reported during the course of the study and follow-up. Multiple regression analysis showed that the success rate of stone removal was associated with stone removal method [odds ratio (OR): 5.35; 95%CI: 2.24-12.77; P=0.00], the transverse diameter of the stone (OR: 2.63; 95%CI: 1.19-5.80; P=0.02) and the presence or absence of diverticulum (OR: 2.35; 95%CI: 1.03-5.37; P=0.04). Postoperative pancreatitis was associated with the EST method of stone removal (OR: 5.00; 95%CI: 1.23-20.28; P=0.02) and whether or not pancreatography was performed (OR: 0.10; 95%CI: 0.03-0.35; P=0.00). CONCLUSION: The EPBID group had a higher success rate of stone removal with a lower incidence of pancreatitis compared with the EST group.
