Abstract：

Objective To explore the effectiveness and safety of endoscopic papillary balloon dilation( EPBD ) for the removal of common bile duct stones. Methods Three hundred and twenty consecutive patients with common bile duct stones on endoscopic retrograde cholangiopancreatography (ERCP) who met all eligibility criteria were randomly assigned endoscopic sphincterotomy (EST) or EPBD.Complications were classified by an expert panel unaware of treatment allocation and outcome. Results After a single ERCP, all stones were removed from 112 patients ( 70% ) assigned EST and 104 ( 65% )assigned EPBD. Mechanical lithotripsy was used to fragment stones in 36 (22. 5% ) EPBD procedures and 32 ( 20. 0% ) EST procedures. Early complications occurred in 5.6% EST patients and 8.1% EPBD patients. No patient died. Gallstone disease recurrence, which is a long-term complication, is 7. 5% ( 12/160) in EST patients and 2.5% (4/160) in EPBD patients, P ＜0. 05. Conclusions The success rate of EPBD was similar to that of EST. We found no evidence of previously suggested higher risk of pancreatitis with EPBD, and suggest that EPBD is preferred in patients who are not suitable for EST, such as those with high risk of bleeding. This procedure is a valuable alternative to EST in patients with bile duct stones.

内镜下乳头气囊扩张对胆总管结石的治疗价值

经内镜乳头括约肌切开术（EST）是治疗性经内镜逆行胰胆管造影术（ERCP）的基础,尤其在胆总管结石的治疗中EST是运用最广泛最成功的内镜下技术.尽管如此,EST仍然有不少短期、长期并发症,如出血、穿孔、胰腺炎及乳头狭窄、胆管炎等[1].1983年,Staritz等[2]介绍了一项可以替代EST的新技术--内镜下乳头气囊扩张术（EPBD）,与EST相比,EPBD的并发症如出血、穿孔发生率明显降低.

内镜下乳头球囊扩张术对比乳头括约肌切开术治疗胆总管结石的Meta分析

目的 对比内镜下乳头球囊扩张术(EPBD)与内镜乳头括约肌切开术(EST)治疗胆总管结石的利与弊.方法 检索Cochrane Library、Embase、Medline、Pubmed、CBM、CNKI、VIP和万方数据库,没有语言限制.纳入从1983年1月到2012年9月间发表的比较EPBD与EST治疗胆总管结石的临床随机对照实验,并对其进行了质量学评价,最后用RevMan 5.1软件进行Meta分析.结果 18个临床随机对照实验符合研究标准(2385个研究对象).在第一次成功取石率、总成功取石率、穿孔、长期胆管炎发生率等方面EPBD与EST结果类似.EPBD有更高的危险发生胰腺炎(RR=1.99,95％ CI:1.41 ～2.81)和重症胰腺炎(RR =4.68,95％ CI:1.36～ 16.11),需要机械碎石的概率更高(RR=1.31,95％CI:1.14～ 1.50).相反的是,EPBD不但有明显低的出血率(RR=0.14,95％ CI:0.06 ～0.34),而且长期结石复发(RR =0.67,95％ CI:0.47～0.96),长期胆囊炎(RR =0.38,95％ CI:0.19 ～0.76)和总的长期并发症(RR =0.52,95％ CI:0.40 ～0.67)发生率更低.结论 考虑出血、结石复发或长期并发症的话,相对于EST,EPBD治疗胆总管结石是更好的选择;但后者胰腺炎尤其是重症胰腺炎的发生率更高.

Small sphincterotomy combined with endoscopic papillary large balloon dilation vs sphincterotomy alone for removal of common bile duct stones

AIM: To evaluate the efficacy and safety of endoscopic papillary large diameter balloon dilation (EPLBD) following limited endoscopic sphincterotomy (EST) and EST alone for removal of large common bile duct (CBD) stones.METHODS: We retrospectively compared EST + EPLBD (group A, n = 64) with EST alone (group B, n = 89) for the treatment of large or multiple bile duct stones. The success rate of stone clearance, procedure-related complications and incidents, frequency of mechanical lithotripsy use, and recurrent stones were recorded.RESULTS: There was no statistically significant difference between the two groups regarding periampullary diverticula (35.9% vs 34.8%, P > 0.05), pre-cut sphincterotomy (6.3% vs 6.7%, P > 0.05), size (12.1 ± 2.0 mm vs 12.9 ± 2.6 mm, P > 0.05) and number (2.2 ± 1.9 vs 2.4 ± 2.1, P > 0.05) of stones or the diameters of CBD (15.1 ± 3.3 mm vs 15.4 ± 3.6 mm, P > 0.05). The rates of overall stone removal and stone removal in the first session were not significantly different between the two groups [62/64 (96.9%) vs 84/89 (94.4%), P > 0.05; and 58/64 (90.6%) vs 79/89 (88.8%), P > 0.05, respectively]. The rates of post-endoscopic retrograde cholangiopancreatography pancreatitis and hyperamylasemia were not significantly different between the two groups [3/64 (4.7%) vs 4/89 (4.5%), P > 0.05; 7/64 (10.9%) vs 9/89 (10.1%), P > 0.05, respectively]. There were no cases of perforation, acute cholangitis, or cholecystitis in the two groups. The rate of bleeding and the recurrence of CBD stones were significantly lower in group A than in group B [1/64 (1.6%) vs 5/89 (5.6%), P < 0.05; 1/64 (1.6%) vs 6/89 (6.7%), P < 0.05, respectively].CONCLUSION: EST + EPLBD is an effective and safe endoscopic approach for removing large or multiple CBD stones.     

Comparison of endoscopic papillary balloon dilatation and endoscopic sphincterotomy for bile duct stones

Endoscopic treatment for bile duct stones is low-invasive and currently considered as the first choice of the treatment. For the treatment of bile duct stones, papillary treatment is necessary, and the treatments used at the time are broadly classified into two types; endoscopic papillary balloon dilatation where bile duct closing part is dilated with a balloon and endoscopic sphincterotomy(EST) where bile duct closing part is incised. Both procedures have advantages and disadvantages. Golden standard is EST, however, there are patients with difficulty for EST, thus we must select the procedure based on understanding of the characteristics of the procedure, and patient backgrounds.     

Is endoscopic papillary balloon dilatation really a risk factor for post-ERCP pancreatitis?

Endoscopic papillary balloon dilatation(EPBD) is useful for decreasing early complications of endoscopic retrograde cholangio-pancreatography(ERCP), including bleeding, biliary infection, and perforation, but it is generally avoided in Western countries because of a relatively high reported incidence of post-ERCP pancreatitis(PEP). However, as the efficacy of endoscopic papillary largeballoon dilatation(EPLBD) becomes widely recognized, EPBD is attracting attention. Here we investigate whether EPBD is truly a risk factor for PEP, and seek safer and more effective EPBD procedures by reviewing past studies. We reviewed thirteen randomised control trials comparing EPBD and endoscopic sphincterotomy(EST) and ten studies comparing direct EPLBD and EST. Three randomized controlled trials of EPBD showed significantly higher incidence of PEP than EST, but no study of EPLBD did. Careful analysis of these studies suggested that longer and higher-pressure inflation of balloons might decrease PEP incidence. The paradoxical result that EPBD with small-calibre balloons increases PEP incidence while EPLBD does not may be due to insufficient papillary dilatation in the former. Insufficient dilatation could cause the high incidence of PEP through the use of mechanical lithotripsy and stress on the papilla at the time of stone removal. Sufficient dilation of the papilla may be useful in preventing PEP.     

改良内镜下乳头气囊扩张术应用的可行性研究

目的探讨改良内镜下乳头气囊扩张术（EPBD）治疗胆管结石的可行性。方法对226例肝外胆管结石的患者应用肠道型柱状气囊行乳头扩张并在此基础上展开治疗，并比较2299例内镜乳头切开术（EST）的治疗效果及术后并发症情况。结果226例患者均顺利完成取石或碎石取石术，术后无胆道感染、穿孔等并发症，发生轻型急性胰腺炎4．7％（10例），与EST（5．2％）比较，差异无统计学意义，术后消化道出血0．47％（1例），与EST（1．2％）比较，差异有统计学意义。结论对EST困难或易发生并发症者用肠道型柱状气囊行EPBD术，能有效地钝性切割乳头，并在此基础上展开较大结石的取石或碎石取石术，同时并发症明显减少。EPBD是内镜下处理胆管结石安全有效的方法之一。     

Therapeutic endoscopic retrograde cholangiopancreatography in a patient with situs inversus viscerum

Situs inversus viscerum(SIV)is a rare congenitalcondition characterized by complete transposition of all viscera.This anatomical pathology makes endoscopic retrograde cholangiopancreatography(ERCP)technically difficult.We report a new case of a 70-year-old Chinese male with total SIV who had obstructive jaundice.Magneticresonance cholangiopancreatography demonstrated a number of stones in the gallbladder and common bile duct(CBD).Therapeutic ERCP was performed to relieve biliary obstruction and remove the CBD stones.This procedure started with the patient in a supine position and the endoscopist at the left side of the table.When the papilla was maintained,the patient was repositioned to a prone position and standard endoscopic sphincterotomy and endoscopic papillary balloon dilatation procedures were conducted.ERCP was performed successfully and relevant complications did not occur in this patient.We also present a review of the literature published between 1985 and 2014in the Pub Med and EMBASE databases.There were eight published cases during this period,with one each from America,Finland,India,Italy,South Korea and Pakistan,and two from Spain.Our case is the first reported in China.
