Short-type single balloon enteroscope for endoscopic retrograde cholangiopancreatography with altered gastrointestinal anatomy

AIM:To evaluate the effectiveness of a short-type single-balloon-enteroscope(SBE) for endoscopic retrograde cholangiopancreatography(ERCP) in patients with a reconstructed intestine.METHODS:Short-type SBE was developed to perform ERCP in postoperative patients with a reconstructed intestine.Short-type SBE is a direct-viewing endoscope with the following specifications:working length,1520 mm;total length,1840 mm;channel diameter,3.2 mm.In addition,short-type SBE has a water-jet channel.The study group comprised 22 patients who underwent 31 sessions of short-type SBE-assisted ERCP from June 2011 through May 2012.Reconstruction was performed by Billroth-Ⅱ(B-Ⅱ) gastrectomy in 6 patients(8 sessions),Roux-en-Y(R-Y) gastrectomy in 14 patients(21 sessions),and R-Y hepaticojejunostomy in 2 patients(2 sessions).We retrospectively studied the rate of reaching the blind end(papilla of Vater or choledochojejunal anastomosis),mean time required to reach the blind end,diagnostic success rate(defined as the rate of successfully imaging the bile and pancreatic ducts),therapeutic success rate(defined as the rate of successfully completing endoscopic treatment),mean procedure time,and complications.RESULTS:Among the 31 sessions of ERCP,the rate of reaching the blind end was 88% in B-Ⅱ gastrectomy,91% in R-Y gastrectomy,and 100% in R-Y hepaticojejunostomy.The mean time required to reach the papilla was 18.3 min in B-Ⅱ gastrectomy,21.1 min in R-Y gastrectomy,and 32.5 min in R-Y hepaticojejunostomy.The diagnostic success rates in all patients and those with an intact papilla were respectively 86% and 86% in B-Ⅱ gastrectomy,90% and 87% in R-Y gastrectomy,and 100% in R-Y hepaticojejunostomy.The therapeutic success rates in all patients and those with an intact papilla were respectively 100% and 100% in B-Ⅱ gastrectomy,94% and 92% in R-Y gastrectomy,and 100% in R-Y hepaticojejunostomy.Because the channel diameter was 3.2 mm,stone extraction could be performed with a wire-guided basket in 12 sessions,and wireguided intraducta     

Double-balloon enteroscopy-assisted endoscopic retrograde cholangiography for Roux-en-Y reconstruction patients with papilla of Vater or bilioenteric anastomosis

Objective. Roux-en-Y reconstructions can be divided into intact papilla of Vater and bilioenteric anastomosis (BEA) with respect to endoscopic retrograde cholangiography (ERC). Double-balloon enteroscopy-assisted ERC (DBE-ERC) may produce different results between the two populations but lacks studies. Material and methods. Forty-seven patients with Roux-en-Y anastomosis undergoing 73 procedures of DBE-ERC were enrolled between July 2007 and August 2013. There were 14 patients with intact papilla of Vater (group A) and 33 patients with BEA (group B). The effectiveness of DBE-ERC, including data of reaching the blind end, performance of ERC, results of endoscopic therapies, and follow-up were retrospectively analyzed and compared between the two groups. Results. For reaching the blind end, the success rate was not different between the groups (85.7% vs. 81.8%, p = 0.7), but the mean procedure time was significantly shorter for group A (28 min vs. 52 min, p = 0.01). For ERC, the success rate was not different between the groups (91.7% vs. 96.3%, p = 0.53), but the mean procedure time was significantly longer for group A (28.4 min vs. 4 min, p < 0.001). All endoscopic therapies could be successfully performed in both groups. No group A patients and five (23.8%) group B patients developed recurrent biliary stricture/stones requiring interventions during a mean follow-up period of 26.1 months. Conclusions. DBE-ERC was effective for both populations with biliary disorders. Reaching the blind end was more difficult but ERC was easier for patients with BEA in terms of procedure time rather than success rates.     

'Short' double-balloon enteroscope endoscopic retrograde cholangiopancreatography in patients with a surgically altered upper gastrointestinal tract

BACKGROUND:

Endoscopic retrograde cholangiopancreatography (ERCP) remains a challenge for endoscopists in patients with surgically altered anatomy of the upper gastrointestinal tract. Double-balloon enteroscopes (DBEs) have revolutionized the ability to access the small bowel. The indication for its therapeutic use is expanding to include ERCP for patients who have undergone small bowel reconstruction. Most of the published experiences in DBE-assisted ERCP have used conventional double-balloon enteroscopes that are 200 cm in length, which do not permit use of the standard ERCP accessories. The authors report their experience with DBE-assisted ERCP using a ‘short’ DBE in patients with surgically altered anatomy.

METHODS:

A retrospective review of patients with previous small bowel reconstruction who underwent ERCP with a ‘short’ DBE at the Centre for Therapeutic Endoscopy and Endoscopic Oncology (Toronto, Ontario) between February 2007 and November 2008 was performed.

RESULTS:

A total of 20 patients (10 men) with a mean age of 57.9 years (range 26 to 85 years) underwent 29 sessions of ERCP with a DBE. Six patients underwent Billroth II gastroenterostomy, seven patients Roux-en-Y hepaticojejunostomy, five patients Roux-en-Y gastrojejunostomy, one patient Roux-en-Y esophagojejunostomy and one patient a Whipple’s operation with choledochojejunostomy. Some patients (n=12 [60%]) underwent previous attempts at ERCP in which the papilla of Vater or bilioenteric anastomosis could not be reached with either a duodenoscope or pediatric colonoscope. All procedures were performed with a commercially available DBE (working length 152 cm, distal end diameter 9.4 mm, channel diameter 2.8 mm). The procedures were performed under conscious sedation with intravenous midazolam, fentanyl and diazepam, except in one patient in whom general anesthesia was administered. Either the papilla of Vater or bilioenteric anastomosis was reached in 25 of 29 cases (86.2%) in a mean duration of 20.8 min (range 5 min to 82 min). Bile duct cannulation was successful in 24 of 25 cases in which the papilla or bilioenteric anastomosis was reached. Therapeutic interventions were successful in 15 patients (24 procedures) including sphincterotomy (n=7), stone extraction (n=9), biliary dilation (n=8), stent placement (n=9) and stent removal (n=8). The mean total duration of the procedures was 70.7 min (range 30 min to 117 min). There were no procedure-related complications.

CONCLUSION:

DBEs enable successful diagnostic and therapeutic ERCP in patients with a surgically altered anatomy of the upper gastrointestinal tract. It is a safe, feasible and less invasive therapeutic option in this group of patients. Standard ‘long’ DBEs have limitations of long working length and the need for modified ERCP accessories. ‘Short’ DBEs are equally as effective in reaching the target limb as standard ‘long’ DBEs, and overcomes some limitations of long DBEs to result in high success rates for endoscopic therapy.     

Endoscopic Retrograde Cholangiopancreatography with Single-Balloon Enteroscopy Is Feasible in Patients with a Prior Roux-en-Y Anastomosis

The purpose of this study is to describe the feasibility of using single-balloon enteroscopy (SBE) to perform endoscopic retrograde cholangiopancreatography (ERCP) in patients who had a prior Roux-en-Y (RY) anastomosis. This case series describes four patients, one with RY gastric bypass, two with RY due to bile duct injury, and one with RY after liver transplantation, who underwent ERCP with SBE. Cholangiography was successful in three of the four patients. In the procedure that was not successful, the enteroenterostomy site could not be located. The successful procedures ranged from 65–91 min in duration. Medication doses were higher than with typical ERCPs. No procedural complications occurred. SBE for ERCP is a feasible option for endoscopic access to the biliary tree in patients with prior RY anastomoses. Limitations of this technique include the time requirement, delay in identification of the enteroenterostomy site, potential learning curve, and immature technology lacking accessories.     

Impact of Scope Exchange from a Long Single Balloon Enteroscope to a Gastroscope during Enteroscopy-Assisted Endoscopic Retrograde Cholangiopancreatography in Patients with Surgically Altered Anatomy

Background/AimsEndoscopic retrograde cholangiopancreatography (ERCP) in patients with surgically altered anatomy (SAA) is challenging to gastrointestinal endoscopists. The aim of this study was to evaluate the impact of scope exchange from a long single balloon enteroscope (SBE) to a gastroscope during SBE-assisted ERCP (SBE-ERCP) in patients with SAA.MethodsPatients who underwent SBE-ERCP between February 2019 and October 2020 were retrospectively identified. Intubation success, scope exchange success, cannulation success, and therapeutic success were analyzed along with complications.ResultsFifty-six patients with various SAAs underwent SBE-ERCP procedures, including Billroth II subtotal gastrectomy (B-II, n=13), pylorus-preserving pancreato-duodenectomy (PPPD, n=6), Roux-en-Y hepaticojejunostomy (REY HJ, n=4), and total gastrectomy with REY anastomosis (TG REY, n=33). Overall intubation, cannulation, and therapeutic success rates were 89.3%, 82.1%, and 82.1%, respectively. Therapeutic success rates did not differ significantly among the type of SAA. Successful scope exchange rate after successful intubation was significantly higher in native papilla (B-II and TG REY, 83.3%, 35/42) compared to bilioenteric anastomosis (PPPD and REY HJ, 0%, 0/8, p<0.001). Intubation success, scope exchange, and cannulation success were associated with therapeutic success (p<0.001). In multivariate analysis, successful scope exchange was the only factor related to cannulation success (p=0.02). The major complication rate was 1.8% (one perforation).ConclusionsSBE-ERCP is a safe and effective procedure to treat biliary problems in patients with SAA. Successful scope exchange may lead to higher therapeutic success by way of cannulation success.     

Improved techniques for double-balloon-enteroscopy-assisted endoscopic retrograde cholangiopancreatography

AIM: To investigate the clinical outcome of double balloon enteroscopy (DBE)-assisted endoscopic retrograde cholangiopancreatography (DB-ERCP) in patients with altered gastrointestinal anatomy.METHODS: Between September 2006 and April 2011, 47 procedures of DB-ERCP were performed in 28 patients with a Roux-en-Y total gastrectomy (n = 11), Billroth II gastrectomy (n = 15), or Roux-en-Y anastomosis with hepaticojejunostomy (n = 2). DB-ERCP was performed using a short-type DBE combined with several technical innovations such as using an endoscope attachment, marking by submucosal tattooing, selectively applying contrast medium, and CO₂ insufflations.RESULTS: The papilla of Vater or hepaticojejunostomy site was reached in its entirety with a 96% success rate (45/47 procedures). There were no significant differences in the success rate of reaching the blind end with a DBE among Roux-en-Y total gastrectomy (96%), Billroth II reconstruction (94%), or pancreatoduodenectomy (100%), respectively (P = 0.91). The total successful rate of cannulation and contrast enhancement of the target bile duct in patients whom the blind end was reached with a DBE was 40/45 procedures (89%). Again, there were no significant differences in the success rate of cannulation and contrast enhancement of the target bile duct with a DBE among Roux-en-Y total gastrectomy (88 %), Billroth II reconstruction (89%), or pancreatoduodenectomy (100%), respectively (P = 0.67). Treatment was achieved in all 40 procedures (100%) in patients whom the contrast enhancement of the bile duct was successful. Common endoscopic treatments were endoscopic biliary drainage (24 procedures) and extraction of stones (14 procedures). Biliary drainage was done by placement of plastic stents. Stones extraction was done by lithotomy with the mechanical lithotripter followed by extraction with a basket or by the balloon pull-through method. Endoscopic sphincterotomy was performed in 14 procedures with a needle precutting knife using a guidewire. The mean total duration of the procedure was 93.6 ± 6.8 min and the mean time required to reach the papilla was 30.5 ± 3.7 min. The mean time required to reach the papilla tended to be shorter in Billroth II reconstruction (20.9 ± 5.8 min) than that in Roux-en-Y total gastrectomy (37.1 ± 4.9 min) but there was no significant difference (P = 0.09). A major complication occurred in one patient (3.5%); perforation of the long limb in a patient with Billroth II anastomosis.CONCLUSION: Short-type DBE combined with several technical innovations enabled us to perform ERCP in most patients with altered gastrointestinal anatomy.     

Comparison between double-balloon and single-balloon enteroscopy in therapeutic ERC after Roux-en-Y entero-enteric anastomosis

AIM: To compare the efficacy of double-balloon enteroscopy (DBE) and single-balloon enteroscopy (SBE) in therapeutic endoscopic retrograde cholangiography (ERC) in patients with Roux-en-Y entero-enteric anastomosis.METHODS: Retrospective analysis of our patient cohort revealed 4 patients with enterobiliary anastomosis and Roux-en-Y entero-enteric anastomosis who underwent repeated ERC with DBE and SBE because of recurrent cholangitis.RESULTS: A total of 38 endoscopic retrograde cholangiopancreatography procedures were performed in 25 patients with Roux-en-Y entero-enteric anastomosis. DBE was used in 29 procedures and SBE in 9. The 4 patients who underwent repeated ERC with DBE and SBE suffered from recurrent cholangitis due to stenosis of the enterobiliary anastomosis. ERC was performed repeatedly to achieve balloon dilation with/without biliary stone extraction and multiple stent placement at the level of the enterobiliary anastomosis. In all 4 patients DBE and SBE were equally successful. Compared to DBE, SBE was equally effective in passing the Roux-en-Y entero-enteric anastomosis, reaching the enterobiliary anastomosis and performing therapeutic ERC.CONCLUSION: This retrospective comparison shows that DBE and SBE are equally successful in the performance of therapeutic ERC at the level of the enterobiliary anastomosis after Roux-en-Y entero-enteric anastomosis.     

Application of single balloon enteroscopy-assisted therapeutic endoscopic retrograde cholangiopancreatography in patients after bilioenteric Roux-en-Y anastomosis: Experience of multi-disciplinary collaboration

BACKGROUND Bilioenteric Roux-en-Y anastomosis is one of the most complicated approaches for reconstructing the gastrointestinal tract, and endoscopic retrograde cholangiopancreatography(ERCP) is technically challenging in patients after bilioenteric Roux-en-Y anastomosis. The optimal endoscopic strategies for such cases remain unknown.AIM To explore the feasibility and effectiveness of single balloon enteroscopy-assisted(SBE-assisted) therapeutic ERCP in patients after bilioenteric Roux-en-Y anastomosis based on multi-disciplinary collaboration between endoscopists and surgeons as well as report the experience from China.METHODS This is a single center retrospective study. All of the SBE-assisted therapeutic ERCP procedures were performed by the collaboration between endoscopists and surgeons. The operation time, success rate, and complication rate were calculated.RESULTS Forty-six patients received a total of 64 SBE-assisted therapeutic ERCP procedures, with successful scope intubation in 60(93.8%) cases and successful diagnosis in 59(92.2%). All successfully diagnosed cases received successful therapy. None of the cases had perforation or bleeding during or after operation,and no post-ERCP pancreatitis occurred.CONCLUSION Based on multi-disciplinary collaboration, SBE-assisted therapeutic ERCP in patients after bilioenteric Roux-en-Y anastomosis is relatively safe and effective and has a high success rate.

Effect of partial gastrectomy with Billroth II or Roux-en-Y anastomosis on postprandial and cholecystokinin-stimulated gallbladder contraction and secretion of cholecystokinin and pancreatic polypeptide

This prospective study was undertaken to determine the effect of partial gastrectomy without vagotomy on postprandial gallbladder contraction and secretion of cholecystokinin (CCK) and pancreatic polypeptide (PP) in 22 peptic ulcer patients randomly assigned to either Billroth II (N = 11) or Roux-en-Y (N = 11) anastomosis. The patients were studied within two weeks before surgery and at six months postoperatively. After surgery basal gallbladder volumes were larger than preoperatively (P less than 0.02). Integrated postprandial gallbladder contraction was not significantly affected by gastrectomy, either in the patients with Billroth II anastomosis (2276 +/- 268 vs 1985 +/- 362%/60 min) or in those with Roux-en-Y anastomosis (2045 +/- 327 vs 2445 +/- 352%/60 min) when studied pre- and postoperatively, respectively. Similarly, integrated postprandial plasma CCK secretion was not significantly changed by either Billroth II gastrectomy (200 +/- 31 vs 166 +/- 21 pM/60 min) or Roux-en-Y gastrectomy (146 +/- 26 vs 147 +/- 12 pM/60 min). However, integrated postprandial PP secretion was significantly (P less than 0.05) lower after Billroth II gastrectomy (6.8 +/- 2.4 vs 2.2 +/- 1.0 nM/60 min), while the reduction in plasma PP after Roux-en-Y gastrectomy just failed to reach statistical significance (6.0 +/- 1.5 vs 3.4 +/- 0.9 nM/60 min). Similarly, the PP response, but not the gallbladder response, to an intravenous bolus injection of 1 IDU CCK/kg body weight was significantly decreased after gastrectomy independent of the type of anastomosis.(ABSTRACT TRUNCATED AT 250 WORDS)     

Large dilating balloon to allow endoscope insertion for successful endoscopic retrograde cholangiopancreatography in patients with surgically altered anatomy (with video)

Background and purpose

Endoscopic retrograde cholangiopancreatography (ERCP) in patients with surgically altered anatomy can be present unique challenges. One of the major obstacles preventing successful ERCP is acute angulation and long afferent loops in patients with Billroth II gastrectomy or Roux-en-Y anastomosis. Here, we described a novel technique for successful endoscope insertion using a large dilating balloon.

Methods

The large dilating balloon (maximum diameter 20 mm) is used as an anchor for endoscope insertion (hooking method) in patients with Billroth II gastrectomy in whom no other endoscopes could be advanced into the end of the duodenum or the Roux-en-Y anastomosis.

Results

The hooking method allows the endoscope to be advanced into the proximal afferent loop, even in patients with sharp angulation of the Y limb.

Conclusions

To the best of our knowledge, this is the first report on the use of a large dilating balloon for endoscope insertion in patients with surgically altered anatomy, in particular Roux-en-Y anastomosis. We believe this technique may be effective for difficult cases like the present case.     

Roux-en-Y改良P袢吻合术对减轻胃癌全胃切除术后胃食管反流病的临床价值

目的评价Roux-en-Y改良P袢吻合术对减轻胃癌全胃切除术后胃食管反流病（GERD）的临床价值。 方法选择2015年10月至2017年3月吉林大学中日联谊医院收治的行全胃切除术的胃癌患者40例。其中19例患者采用常规Roux-en-Y吻合术（常规Roux-en-Y吻合术组）,21例患者采用改良P袢吻合术（改良P袢吻合术组）。采用GerdQ量表评估所有患者术后1年出现GERD的情况。采用χ²检验比较2组患者GERD发生率差异。 结果所有患者手术均获得成功,无一例患者死亡。改良P袢吻合术组患者术后1年GERD发生率为4.8% （1/21）,低于常规Roux-en-Y吻合术组的42.1% （8/19）,且差异有统计学意义（χ²=7.98,P<0.05）。 结论Roux-en-Y改良P袢吻合术能显著减少胃癌全胃切除术后GERD的发生。     

弯头型造影导丝与超滑亲水性软头导丝在内镜胰胆管插管中的对比研究

目的评价弯头型血管造影导丝（泥鳅导丝）与超滑亲水性软头导丝（斑马导丝）在经内镜逆行胰胆管造影术（ERCP）插管中的效果优劣。方法196例患者随机分为泥鳅导丝组和斑马导丝组,均为98例,行导丝引导下的切开刀插管,首次插管如果10min未成功则交换导丝重新插管10min,如再次插管超过10min则视为插管失败,将采用其他辅助插管技术。观察插管时间、插管成功率,以及术后腹痛与淀粉酶情况。结果泥鳅导丝组首次插管成功率高于斑马导丝组（93．9％比86．7％,P〈0．05）,但插管时间差异无统计学意义;交换导丝后,泥鳅导丝插管成功率仍然高于斑马导丝（76．9％比0．0％,P〈0．05）。术后淀粉酶升高与胰腺炎发生率两组间差异无统计学意义（P〉0．05）。结论泥鳅导丝ERCP插管优于斑马导丝,在困难插管时可以替代斑马导丝。     

Endoscopic ultrasound-guided vs endoscopic retrograde cholangiopancreatography biliary drainage for obstructed distal malignant biliary strictures: A systematic review and meta-analysis

BACKGROUND For palliation of malignant biliary obstruction(MBO), the gold-standard method of biliary drainage is endoscopic retrograde cholangiopancreatography(ERCP)with the placement of metallic stents. Endoscopic ultrasound(EUS)-guided drainage is an alternative that is typically reserved for cases of ERCP failure.Recently, however, there have been robust randomized clinical trials(RCTs)comparing EUS-guided drainage and ERCP as primary approaches to MBO.AIM To compare EUS guidance and ERCP in terms of their effectiveness and safety in palliative biliary drainage for MBO.METHODS This was a systematic review and meta-analysis, in which we searched the MEDLINE, Excerpta Medica, and Cochrane Central Register of Controlled Trials databases. Only RCTs comparing EUS and ERCP for primary drainage of MBO were eligible. All of the studies selected provided data regarding the rates of technical and clinical success, as well as the duration of the procedure, adverse events, and stent patency. We assessed the risk of biases using the Jadad score and the quality of evidence using the Grading of Recommendations Assessment,Development and Evaluation criteria.RESULTS The database searches yielded 5920 records, from which we selected 3 RCTs involving a total of 222 patients(112 submitted to EUS and 110 submitted to ERCP). In the EUS and ERCP groups, the rate of technical success was 91.96%n and 91.81%, respectively, with a risk difference(RD) of 0.00%(95%CI:-0.07, 0.07;P = 0.97; I~2 = 0%). The clinical success was 84.81% and 85.53% in the EUS and ERCP groups, respectively, with an RD of-0.01%(95%CI:-0.12, 0.10; P = 0.90; I~2 =0%). The mean difference(MD) for the duration of the procedure was-0.12%(95%CI:-8.20, 7.97; P = 0.98; I~2 = 84%). In the EUS and ERCP groups, there were14 and 25 adverse events, respectively, with an RD of-0.06%(95%CI:-0.23, 0.12; P= 0.54; I~2 = 77%). The MD for stent patency was 9.32%(95%CI:-4.53, 23.18; P =0.19; I~2 = 44%). The stent dysfunction rate was significantly lower in the EUS t group(MD =-0.22%; 95 CI:-0.35,-0.08; P = 0.001; I~2 = 0%).CONCLUSION EUS represents an interesting alternative to ERCP for MBO drainage,demonstrating lower stent dysfunction rates compared with ERCP. Technical and clinical success, duration, adverse events and patency rates were similar.     

Endoscopic transpancreatic septotomy as a precutting technique for difficult bile duct cannulation

AIM: To evaluate the technique of transpancreatic septotomy(TS) for cannulating inaccessible common bile ducts in endoscopic retrograde cholangiopancreatography(ERCP).METHODS: Between May 2012 and April 2013, 1074 patients were referred to our department for ERCP. We excluded 15 patients with previous Billroth Ⅱ gastrectomy, Roux-en-Y anastomosis, duodenal stenosis, or duodenal papilla tumor. Among 1059 patients who underwent ERCP, there were 163 patients with difficult bile duct cannulation. Pancreatic guidewire or pancreatic duct plastic stent assistance allowed for successful ERCP completion in 94 patients. We retrospectively analyzed clinical data from 69 failed patients(36 transpancreatic septotomies and 33 needle-knife sphincterotomies). RESULTS: Of the 69 patients who underwent precut papillotomy, common bile duct cannulation was successfully achieved in 67. The success rates in the TS and needle knife sphincterotomy(NKS) groups were 97.2%(35/36) and 96.9%(32/33), respectively, which were not significantly different(P 0.05). Complications occurred in 11 cases, including acute pancreatitis(n = 6), bleeding(n = 2), and cholangitis(n = 3). The total frequency of complications in the TS group was lower than that in the NKS group(8.3% vs 24.2%, P 0.05).CONCLUSION: Pancreatic guidewire or pancreatic duct plastic stent assistance improves the success rate of selective bile duct cannulation in ERCP. TS and NKS markedly improve the success rate of selective bile duct cannulation in ERCP. TS precut is safer as compared with NKS.     

Evaluation of a voice recognition system for generation of therapeutic ERCP reports

We evaluated a computerized report-generating system using voice recognition technology (EndoSpeak) for producing therapeutic ERCP reports. For 30 consecutive ERCP cases, reports using both EndoSpeak and standard dictation were generated at the end of the procedure. The cases were scored for overall difficulty and the number of component procedures performed. The time to generate a report with EndoSpeak was significantly longer than with dictation (10.0 +/- 2.9 (SD) min vs. 6.5 +/- 1.6 min, p less than 0.0001), and this difference was greater for more lengthy reports (r = 0.85, p less than 0.001). The procedure difficulty score and the number of component procedures were both significant predictors of the physician's report generation time for EndoSpeak and dictation. Dictated reports were judged to have a higher information content than EndoSpeak reports for 90% of the cases (p less than 0.00001). Several specific difficulties were encountered with the EndoSpeak software. Although EndoSpeak offers promise, substantial software modifications will be required before this system can become competitive with dictation for therapeutic ERCP reports.     

乳头扩约肌预切开术在困难插管内镜逆行胰胆管造影术中的疗效分析

目的 探讨十二指肠乳头预切开术在内镜逆行胰胆管造影术( ERCP)中的应用,并评价其在ERCP中的作用和安全性.方法 自2008年1月至2011年6月我院肝胆胰外科共完成内镜下逆行胰胆管造影术930例,其中选择性插管困难者采用常规方法不能完成而采用乳头预切开术108例,占11.6％.纳入标准为常规插管失败或反复进入胰管4次判定为选择性插管困难,术中改行乳头预切开术,根据病情完成ERCP检查和内镜下治疗.观察终点为治疗成功率和并发症发生率,并与同期常规ERCP插管病例资料对比分析.统计学处理采用SPSS 13.0统计软件,率的比较采用x2检验,P＜0.05为差异有统计学意义.结果 本组乳头预切开术108例,ERCP成功103例,成功率95.4％.术后并发症7例,发生率6.5％,无十二指肠穿孔及死亡病例.同期822例常规ERCP诊治成功率97.7％,术后并发症63例,发生率7.7％.乳头预切开与常规选择性胆管插管两组患者的并发症发生率(x2=0.141,P=0.707)及成功率(x2=2.041,P=0.153)差异无统计学意义.结论 乳头预切开术与常规ERCP相比不增加发生并发症的风险,可提高困难ERCP的成功率,但要严格掌握适应证,由经验丰富的医师进行.     

两种不同全胃切除术治疗对胃上、中癌患者术后发生反流性食管炎的影响

目的通过2种不同全胃切除术术方式的比较,探讨全胃切除Roux-en-Y吻合术及全胃切除毕II式吻合＋Braun吻合对反流性食管炎的影响。 方法选取2015年8月至2017年1月,新疆维吾尔自治区人民医院就诊的80例胃上、中癌患者行全胃切除术的临床资料。在病期允许的前提下将患者分成2组,试验组42例,对照组38例。术后随访1年内反流性食管炎的发生率。 结果全胃切除Roux-en-Y吻合术组反流性食管炎发生率为14.3%,显著低于全胃切除毕Ⅱ式吻合＋Braun吻合的55.3%,差异有统计学意义（χ²=7.372,P<0.05）。 结论全胃切除Roux-en-Y吻合术术后发生反流性食管炎的可能性更低。     

ERCP using double-balloon endoscopes in patients with Roux-en-Y anastomosis

Introduction

Endoscopic retrograde cholangiopancreatography (ERCP) and associated procedures are difficult to perform in patients with a Roux-en-Y reconstruction. Therefore, at present, at many institutions, ERCP is not generally performed for those with a Roux-en-Y anastomosis.

Methods

However, double-balloon endoscopes (DBEs) have dramatically changed this situation.

Results

The use of a DBE enables an endoscopic approach into the deeply situated small intestine, which has been difficult with a conventional endoscope. Therefore, ERCP for patients with a Roux-en-Y anastomosis has been attempted using a DBE, and good results have been reported.

Conclusion

The development of DBEs has created the possibility of performing ERCP for patients with Roux-en-Y reconstruction in whom an endoscopic approach has conventionally been believed to be difficult.     

长海医院2001年与2007年ERCP成功率和并发症比较研究

目的探讨近年ERCP适应证、难度分级、术后并发症及严重程度的变化趋势。方法回顾性总结了上海长海医院2001年和2007年2374例ERCP临床资料（2001年966例,2007年1408例）。比较了两组患者基本信息、ERCP适应证、操作难度、成功率、ERCP术后并发症发生率和严重程度。结果相隔5年的2个自然年中,2007年比2001年因胆道结石行ERCP的患者明显下降（49．3％比59．0％,P=0．000）,而胰腺疾病特别是慢性胰腺炎的比例显著上升（18．5％比6．6％,P=0．000）,复发性胰腺炎比例上升（1．6％比0．2％,P=0．001）,2007年出现肝移植术后胆道狭窄行ERCP的患者。2007年手术操作难度明显高于2001年（P=0．000）,难度为5级的操作显著增加（33．3％比7．3％,P=0．000）,诊断性ERCP（难度1级＋难度3级）的比例明显下降（5．9％＋3．1％比30．5％＋2．8％,P=0．000）。2001和2007年ERCP成功率相似（P=0．084）。2007年ERCP术后并发症发生率明显高于2001年（7．88％比3．73％,P=0．000）,但并发症的严重程度无统计学差异（P=0．820）。结论2007年诊断性ERCP的例数明显下降;ERCP操作适应证发生了变化,其中胆道疾病减少,胰腺疾病增多;操作更加复杂,成功率并无下降。ERCP术后并发症发生率上升可能是因为治疗性ERCP增加的缘故。
