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

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

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 choledocho-lithiasis 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.

Clinical Application of Primary Suture Following Three-Port Laparoscopic Common Bile Duct Exploration: A Report of 176 Cases

Objective: To investigate the feasibility, safety and the clinical value of primary suture following 3-port laparoscopic common bile duct exploration (LCBDE). Methods: From January 2012 to September 2014, 176 patients suffered from choledocholithiasis were treated with primary suture following 3-port LCBDE and the clinical data were retrospectively analyzed. Results: All cases were operated successfully and none was converted to open surgery. The duration of operation was 92.2 ± 18.8 min and the length of postoperative hospital stay was 4.4 ± 3.7 d. Postoperative bile leakage occurred in 2 cases and these patients recovered by simple drainage for 3 to 7 days without re-operation. All patients recovered smoothly without any serious complications. Conclusions: Primary suture following 3-port LCBDE is safe, effective and mini-invasive, which is worthy of further clinical application.

Laparoscopic common bile duct exploration to treat choledocholithiasis in situs inversus patients:A technical review

Situs inversus(SI)is a rare congenital condition characterized by a mirror-image transposition of the major visceral organs.Since the 1990s,more than one hundred SI patients have been reported to have successfully undergone laparoscopic cholecystectomy.In these cases,the major problem is to overcome is the left-right condition for right-handed surgeons.Laparoscopic common bile duct exploration(LCBDE),an alternative to treat patients with bile duct stones,has shown equivalent efficacy and is less likely to cause pancreatitis than endoscopic retrograde cholangiopancreatography.Recent updated meta-analyses revealed that a shorter postoperative hospital stay,fewer procedural interventions,cost-effectiveness,a higher stone clearance rate,and fewer perioperative complications are additional advantages of LCBDE.However,the technique is technically demanding,even for skilled laparoscopic surgeons.Conducting LCBDE in patients with difficult situations,such as SI,is more complex than usual.We herein review published SI patients with choledocholithiasis treated by LCBDE,including our own experience,and this paper focuses on the technical aspects.

Laparoscopic hepatic left lateral lobectomy combined with fiber choledochoscopic exploration of the common bile duct and traditional open operation

AIM: To investigate the possibilities and advantages of laparoscopic hepatic left lateral lobectomy combined with fiber choledochoscopic exploration of the common bile duct compaired with traditional open operation.METHODS: Laparoscopic hepatic left lateral lobectomy combined with fiber choledochoscopic exploration of the common bile duct and traditional open operation were performed in two groups of patients who had gallstones in the left lobe of liver and in the common bile duct. The hospitalization time, hospitalization costs, operation time, operative complications and post-operative liver functions of the two groups of patients were studied.RESULTS: The operation time and post-operative liver functions of the two groups of patients had no significant differences, while the hospitalization time, hospitalization costs and operative complications of the laparoscopic hepatic left lateral lobectomy combined with fiber choledochoscopic exploration in the common bile duct group were significantly lower than those in the traditional open operation group.CONCLUSION: For patients with gallstones in the left lobe of liver and in the common bile duct, laparoscopic hepatic left lateral lobectomy combined with fiber choledochoscopic exploration of the common bile duct can significantly shorten the hospitalization time, reduce the hospitalization costs and the post-operative complications,without prolonging the operation time and bringing about more liver function damages compared with traditional open operation. This kind of operation has more advantages than traditional open operation.

Role of laparoscopic common bile duct exploration in the management of choledocholithiasis

Surgical fraternity has not yet arrived at any consensus for adequate treatment of choledocholithiasis. Sequential treatment in the form of pre-operative endoscopic retrograde cholangio-pancreatography followed by laparoscopic cholecystectomy(LC) is considered as optimal treatment till date. With refinements in technique and expertise in field of minimal access surgery, many centres in the world have started offering one stage management of choledocholithiasis by LC with laparoscopic common bile duct exploration(LCBDE). Various modalities have been tried for entering into concurrent common bile duct(CBD) [transcystic(TC) vs transcholedochal(TD)], for confirming stone clearance(intraoperative cholangiogram vs choledochoscopy), and for closure of choledochotomy(T-tube vs biliary stent vs primary closure) during LCBDE. Both TC and TD approaches are safe and effective. TD stone extraction is involved with an increased risk of bile leaks and requires more expertise in intra-corporeal suturing and choledochoscopy. Choice depends on number of stones, size of stone, diameter of cystic duct and CBD. This review article was undertaken to evaluate the role of LCBDE for the management of choledocholithiasis.

Two-stage vs single-stage management for concomitant gallstones and common bile duct stones

AIM:To evaluate the safety and effectiveness of twostage vs single-stage management for concomitant gallstones and common bile duct stones.METHODS:Four databases,including PubMed,Embase,the Cochrane Central Register of Controlled Trials and the Science Citation Index up to September 2011,were searched to identify all randomized controlled trials(RCTs).Data were extracted from the studies by two independent reviewers.The primary outcomes were stone clearance from the common bile duct,postoperative morbidity and mortality.The secondary outcomes were conversion to other procedures,number of procedures per patient,length of hospital stay,total operative time,hospitalization charges,patient acceptance and quality of life scores.RESULTS:Seven eligible RCTs [five trials(n = 621) comparing preoperative endoscopic retrograde cholangiopancreatography(ERCP)/endoscopic sphincterotomy(EST) + laparoscopic cholecystectomy(LC) with LC + laparoscopic common bile duct exploration(LCBDE);two trials(n = 166) comparing postoperative ERCP/EST + LC with LC + LCBDE],composed of 787 patients in total,were included in the final analysis.The metaanalysis detected no statistically significant difference between the two groups in stone clearance from the common bile duct [risk ratios(RR) =-0.10,95% confidence intervals(CI):-0.24 to 0.04,P = 0.17],postoperative morbidity(RR = 0.79,95% CI:0.58 to 1.10,P = 0.16),mortality(RR = 2.19,95% CI:0.33 to 14.67,P = 0.42),conversion to other procedures(RR = 1.21,95% CI:0.54 to 2.70,P = 0.39),length of hospital stay(MD = 0.99,95% CI:-1.59 to 3.57,P = 0.45),total operative time(MD = 12.14,95% CI:-1.83 to 26.10,P = 0.09).Two-stage(LC + ERCP/EST) management clearly required more procedures per patient than single-stage(LC + LCBDE) management.CONCLUSION:Single-stage management is equivalent to two-stage management but requires fewer procedures.However,patient's condition,operator's expertise and local resources should be taken into account in making treatment decisions.

Outcomes of laparoscopic bile duct exploration for choledocholithiasis with small common bile duct

BACKGROUND Laparoscopic cholecystectomy(LC)combined with laparoscopic common bile duct(CBD)exploration(LCBDE)is one of the main treatments for choledocholithiasis with CBD diameter of larger than 10 mm.However,for patients with small CBD(CBD diameter≤8 mm),endoscopic sphincterotomy remains the preferred treatment at present,but it also has some drawbacks associated with a series of complications,such as pancreatitis,hemorrhage,cholangitis,and duodenal perforation.To date,few studies have been reported that support the feasibility and safety of LCBDE for choledocholithiasis with small CBD.AIM To investigate the feasibility and safety of LCBDE for choledocholithiasis with small CBD.METHODS A total of 257 patients without acute cholangitis who underwent LC+LCBDE for cholecystolithiasis from January 2013 to December 2018 in one institution were reviewed.The clinical data were retrospectively collected and analyzed.According to whether the diameter of CBD was larger than 8 mm,257 patients were divided into large CBD group(n=146)and small CBD group(n=111).Propensity score matching(1:1)was performed to adjust for clinical differences.The demographics,intraoperative data,short-term outcomes,and long-term follow-up outcomes for the patients were recorded and compared.RESULTS In total,257 patients who underwent successful LC+LCBDE were enrolled in the study,146 had large CBD and 111 had small CBD.The median follow-up period was 39(14-86)mo.For small CBD patients,the median CBD diameter was 0.6 cm(0.2-2.0 cm),the mean operating time was 107.2±28.3 min,and the postoperative bile leak rate,rate of residual CBD stones(CBDS),CBDS recurrence rate,and CBD stenosis rate were 5.41%(6/111),3.60%(4/111),1.80%(2/111),and 0%(0/111),respectively;the mean postoperative hospital stay was 7.4±3.6 d.For large CBD patients,the median common bile duct diameter was 1.0 cm(0.3-3.0 cm),the mean operating time was 115.7±32.0 min,and the postoperative bile leak rate,rate of residual CBDS,CBDS recurrence rate,and CBD stenosis rate were 5.41%(9/146),1.37%(2/146),6.85%(10/146),and 0%(0/146),respectively;the mean postoperative hospital stay was 7.7±2.7 d.After propensity score matching,184 patients remained,and all preoperative covariates except diameter of CBD stones were balanced.Postoperative bile leak occurred in 11 patients overall(5.98%),and no difference was found between the small CBD group(4.35%,4/92)and the large CBD group(7.61%,7/92).The incidence of CBDS recurrence did not differ significantly between the small CBD group(2.17%,2/92)and the large CBD group(6.52%,6/92).CONCLUSION LC+LCBDE is safe and feasible for choledocholithiasis patients with small CBD and did not increase the postoperative bile leak rate compared with choledocholithiasis patients with large CBD.

Hem-o-lok clip migration to the common bile duct after laparoscopic common bile duct exploration:A case report

BACKGROUND Laparoscopic cholecystectomy(LC)and laparoscopic common bile duct exploration(LCBDE)has been widely used for management of gallbladder and common bile duct(CBD)stones.Post-operative clip migration is a rare complication of laparoscopic biliary surgery,which can serve as a nidus for stone formation and cause recurrent cholangitis.CASE SUMMARY A 59-year-old female was admitted to hospital because of fever and acute right upper abdominal pain.She has a history of LC and had a LCBDE surgery 2 mo ago.Physical examination revealed tenderness in the upper quadrant of right abdomen.Computed tomography scan demonstrated a high-density shadow at the distal CBD,which was considered as migrated clips.The speculation was confirmed by endoscopic retrograde cholangiopancreatography examination,and two displaced Hem-o-lok clips were removed with a stone basket.No fever or abdominal pain presented after the operation.In addition to the case report,literature regarding surgical clip migration after laparoscopic biliary surgery was reviewed and discussed.CONCLUSION Incidence of postoperative clip migration may be reduced by using clips properly and correctly;however,new methods should be explored to occlude cystic duct and vessels.If a patient with a past history of LC or LCBDE presents with features of sepsis and recurrent upper quadrant pain,clip migration must be considered as one of the differential diagnosis.

Sinistroposition of the gallbladder and common bile duct

BACKGROUND: Despite its rare incidence, few cases of left-side gallbladder have been already published. METHODS: We reported herein the case of a 29-year-old man with a left liver tumor in whom left lateral bisegmen- tectomy was mandatory. It represents the first description of a sinistroposition of both gallbladder and common bile duct. RESULTS: Surgical exploration revealed a left-side gall- bladder , located under the left lobe of the liver. During he- patic parenchyma dissection at the left side of the round liga- ment and the Rex recessus, the common bile duct was in- jured. Complete separation of hepatic pedicle structures showed that the upper biliary convergence passed on the left side of the Rex recessus before reaching the hepatoduo- denal ligament. CONCLUSION: Only careful dissection of the hepatoduo- denal ligament up to Rex recessus level prior to liver paren- chyma resection could avoid biliary tract injury during left lobectomy.

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 twosession(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 singlesession 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.

Clinical observation of laparoscopic cholecystectomy combined with endoscopic retrograde cholangiopancreatography or common bile duct lithotripsy

BACKGROUND The incidence of common bile duct(CBD) stones accounts for approximately 10%–15% of all CBD diseases.Approximately 8%–20% of these patients also have gallstones with heterogenous signs and symptoms.AIM To investigate the clinical effects of laparoscopic cholecystectomy(LC) combined with endoscopic retrograde cholangiopancreatography(ERCP) and LC with CBD excision and stone extraction in one-stage suture(LBEPS) for the treatment of gallbladder and CBD stones.METHODS Ninety-four patients with gallbladder and CBD stones were selected from our hospital from January 2018 to June 2021.They were randomly divided into study and control groups with 47 patients each.The study group underwent LC with ERCP,and the control group underwent LC with LBEPS.Surgery,recovery time of gastrointestinal function,complication rates,liver function indexes,and stress response indexes were measured pre-and postoperatively in both the groups.RESULTS The durations of treatment and hospital stay were shorter in the study group than in the control group.There was no significant difference between the one-time stone removal rate between the study and control groups.The time to anal evacuation,resumption of oral feeding,time to bowel sound recovery,and time to defecation were shorter in the study group than in the control group.The preoperative serum direct bilirubin(DBIL),total bilirubin(TBIL),and alanine aminotransferase(ALT) levels were insignificantly higher in the study group than that in the control group.A day after surgery,the postoperative serum DBIL,TBIL,and ALT levels were lower than their preoperative levels in both groups,and of the two groups,the levels were lower in the study group.Although the preoperative serum adrenocorticotrophic(ACTH),cortisol(COR),epinephrine(A),and norepinephrine(NE) levels were higher in the study group than that in the control group,these differences were not significant(P > 0.05).The serum ACTH,COR,A,and NE levels in both groups decreased one day after surgery compared to the preoperative levels,but the inter-group difference was statistically insignificant.Similarly,(91.79 ±10.44) ng/mL,A,and NE levels were lower in the study group than in the control group.The incidence of complications was lower in the study group than in the control group.CONCLUSION LC combined with ERCP induces only a mild stress response;this procedure can decrease the risk of complications,improve liver function,and achieve and promote a faster recovery of gastrointestinal functions.

Synchronous double cancers of the common bile duct

We report an extremely rare case of synchronous double cancers of the common bile duct without pancreaticobiliary maljunction.Only two similar cases have been reported in the English literature.Endoscopic retrograde cholangiopancreatography showed a tuberous filling defect in the middle and superior parts of the common bile duct,and mild stenosis in the inferior duct.Computed tomography(CT) showed a well enhanced mass in the middle and superior parts of the common bile duct.A single cancer of the middle and superior bile duct was suspected and extra-hepatic bile duct resection was performed.CT eleven months after surgery revealed enhanced inferior bile duct wall and a slightly enhanced tumor within it.Retrospective review of the CT images taken before first surgery showed enhanced inferior bile duct wall without intrabiliary tumor only on the delayed phase.The inferior bile duct tumor was suspected to have originally co-existed with the middle and superior bile duct tumor.Pancreaticoduodenectomy was performed subsequently.Histopathological examination revealed that the middle and superior bile duct tumor was a moderately differentiated tubular adenocarcinoma while the inferior bile duct tumor was a papillary adenocarcinoma.The two tumors were separated and had different histological findings and growth patterns,further suggesting that they were two primary cancers.

Complications of Laparoscopic Choledochotomy and Lithotomy for Primary Suture

Objective:To explore the non-placement of“T”tube after laparoscopic choledochotomy.feasibility and complication analysis of primary suture bile duct.Methods:Retrospective analysis of January 2013~December 2016,Laparoscopic choledocholithotomy for primary bile duct suture in 87 cases,Combined with literature,the indications,methods and complications of the operation were summarized and analyzed.Results:There was no operative death in the whole group,Postoperative complications occurred in 5 cases(5.7%),1 case with jaundice,gradually subsided after 4 days of conservative treatment.Two cases had postoperative bile leakage,to prolong the drainage time of the peritoneal drainage tube and stop by itself.In 1 case,bile duct stenosis occurred.1 case of residual common bile duct stones.The average postoperative hospitalization was 9 days.Conclusion:Select the right case strictly,Patient and delicate operation,Laparoscopic choledochotomy is safe and feasible.

Clinical efficacy and safety of selective trans-cystic intra-operative cholangiography in primary suture following three-port laparoscopic common bile duct exploration

Background Intra-operative cholangiography has been shown to be a sensitive and specific method of demonstrating bile duct stones. This study investigated the feasibility, safety, and clinical value of selective trans-cystic intra-operative cholangiography in primary suture following three-port laparoscopic common bile duct exploration, and identified the factors that positively predict the presence of common bile duct stones. Methods From January 2008 to January 2011, 252 of 1013 patients undergoing laparoscopic cholecystectomy received selective trans-cystic intra-operative cholangiography and primary suture following three-port laparoscopic common bile duct exploration. Their clinical data were analyzed retrospectively. Results All operations were successful and none was converted to open surgery. The intra-operative cholangiography time was （8.3±2.5） minutes, and the operative duration was （105.4±23.1） minutes. According to selective intra-operative cholangiography, the positive predictive values of current jaundice, small gallstones （〈0.5 cm） and dilated cystic duct （〉0.3 cm）, dilated common bile duct （〉0.8 cm）, history of jaundice or gallstone pancreatitis, abnormal liver function test, and preoperative demonstration of suspected common bile duct stones on imaging were 87%, 25%, 42%, 15%, 32%, and 75% for common bile duct stones, respectively. Patients with several factors suggestive of common bile duct stones yielded higher numbers of positive cholangiograms. Unexpected stones were found in 13 patients （5.2%） by intra-operative cholangiography. The post-operative hospital stay was （4.7±2.2） days. Post-operative bile leakage occurred in two cases, and these patients recovered by simple drainage for 3-7 days without re-operation. Of the 761 patients who underwent laparoscopic cholecystectomy alone, 5 （0.7%） presented with a retained common bile duct stone requiring intervention. The median follow-up was 12 months, and only one patient who once suffered from bile leakage presented with obstructive jaundice due to bile duct stenosis 6 months postoperatively. The other patients recovered without any serious complications. Conclusions Selective intra-operative cholangiography yields acceptably high positive results. It is a safe, effective, and minimally invasive approach in patients with suspected choledocholithiasis and primary suture following three-port laparoscopic common bile duct exploration.

LC+LERV与LC+LCBDE治疗胆囊结石合并胆总管结石的临床效果比较

目的通过对比分析腹腔镜胆囊切除术(LC)+腹腔镜术中联合内镜(LERV)与LC+腹腔镜胆总管切开取石(LCBDE)对胆囊结石合并胆总管结石的临床疗效,探讨两种手术方式的临床应用价值。方法前瞻性分析2021年12月至2023年5月江油市人民医院和潍坊市人民医院收治的110例胆囊结石合并胆总管结石患者的临床资料,按随机数字表法分为LC+LERV组(n=54)和LC+LCBDE组(n=56),对两组患者的手术成功率、术中出血量、手术时间、引流管留置时间、术后并发症、疼痛视觉模拟评分(VAS)、平均住院时间以及住院费用进行比较分析。结果与LC+LCBDE组相比,LC+LERV组手术成功率较低[47(87.04%)vs 56(100.00%),χ2=7.467,P=0.006],手术时间较长[(112.0±15.6)min vs(98.0±21.5)min,t=3.771,P<0.001],但引流管留置时间明显较短[(2.34±0.66)d vs(7.41±12.88)d,t=-2.693,P=0.008],两组比较差异均具有统计学意义(P<0.05)。两组在术中出血量、术后并发症发生率方面比较,差异无统计学意义(P>0.05);两组在术前、术后6 h、术后1 d及出院日VAS评分差异无统计学意义(P>0.05),但术后3 d LC+LCBDE组VAS评分高于LC+LERV组(P<0.05)。两组平均住院时间差异无统计学意义(P>0.05),但LC+LERV组平均住院费用明显高于LC+LCBDE组[(25653.6±3317.0)元vs(17978.4±2158.0)元,t=14.219,P<0.001]。结论在治疗胆囊结石合并胆总管结石方面,LC+LCBDE和LC+LERV安全性上表现一致,LC+LERV术后舒适性更佳,但LC+LCBDE在治疗有效性、经济效率性方面更好,且LC+LCBDE可作为LC+LERV插管或取石失败后的补救术式。根据具体病情个性化选择手术方式,有利优势互补,获得最佳治疗效果。

腹腔镜胆总管探查一期缝合术适应证及胆漏防治4100例临床经验

目的探讨腹腔镜胆总管探查(LCBDE)一期缝合适应证及胆漏并发症防治技术。方法回顾性分析2000年1月至2023年8月我院收治的4100例胆囊结石合并胆总管结石行LCBDE一期缝合术患者的临床资料,包括病例纳入标准、技术方法及胆漏并发症的防治经验。结果4100例LCBDE一期缝合术均顺利完成,无中转开腹。术后3991例(97.34%)恢复顺利,109例(2.66%)发生胆漏。其中101例(2.46%)漏胆不伴腹膜炎50~200 ml/d,乳胶管引流1~2周自愈,8例(0.19%)胆漏伴腹膜炎再次手术胆总管置T管及腹腔引流术,本组无死亡病例。结论胆总管结石采用LCBDE一期缝合术的方法是安全有效而且有优势的选择术式。

LCBDE术中一期缝合与T管引流的术后胆漏发生率比较

目的比较腹腔镜胆总管探查术中(LCBDE)行一期缝合和T管引流的术后胆漏发生率,并分析术后胆漏的危险因素。方法回顾性分析2015年1月至2022年11月于温州医科大学附属第一医院行LCBDE的患者资料,分为一期缝合组和T管引流组,采用Logistic多因素回归分别分析两组发生胆漏的危险因素。对两组中有肝内结石、上段胆总管结石、最大结石直径、体温最高值和中性粒细胞百分比5项指标进行倾向性评分匹配(PSM)后,比较两组胆漏发生率。结果共纳入患者1052例,其中143例患者发生术后胆漏,发生率为13.5%。Logistic多因素回归分析显示年龄>60岁为一期缝合组(n=506)胆漏的危险因素(OR=2.242,95%CI 1.300-4.038,P=0.005),主刀医师实施LCBDE少于10例为T管引流组(n=546)胆漏的危险因素(OR=3.525,95%CI 1.469-7.996,P=0.003)。经PSM成功匹配383对患者,一期缝合组胆漏发生率较T管引流组高[15.1%(58/383)vs 9.9%(38/383),P=0.029]。结论患者年龄>60岁是行LCBDE术中一期缝合后发生胆漏的独立危险因素,医师经验不足(主刀医师实施LCBDE少于10例)是行留置T管后发生胆漏的独立危险因素。相较于一期缝合,留置T管引流可以降低LCBDE术后胆漏的发生率。

Primary duct closure versus T-tube drainage after laparoscopic common bile duct exploration:a meta-analysis

Background and aims:Laparoscopic common bile duct exploration(LCBDE)is considered a safe and effective method for the removal of bile duct stones.However,the choice of primary duct closure(PDC)or T-tube drainage(TTD)technique after LCBDE is still controversial.This study aimed to compare the safety and effectiveness of PDC and TTD after LCBDE.Methods:Studies published before May 1,2021 in Pub Med,Web of Science,and Cochrane Library databases were searched to screen out randomized controlled trials(RCTs)and cohort studies to compare PDC with TTD.Meta-analyses of fixed effect and random effect models were performed using Rev Man 5.3.Results:A total of 1865 patients were enrolled in six RCTs and ten cohort studies.Regarding RCTs,the PDC group was significantly better than the TTD group in terms of operation time,total postoperative complications,postoperative hospital stay,and hospitalization expenses(all P<0.05).Based on cohort studies of the subgroup,the PDC group had shorter operation time,shorter postoperative hospital stay,less intraoperative blood loss,and limited total postoperative complications.Statistically,there were no significant differences in bile leakage,retained stones,stone recurrence,bile duct stricture,postoperative pancreatitis,other complications,or postoperative exhaust time between the TTD and PDC groups.Conclusions:Based on the available evidence,compared with TTD,PDC is safe and effective,and can be used as the first choice after transductal LCBDE in patients with choledocholithiasis.
