In 5%-10% of cases, the CBD remains inaccessible, necessitating pre-cut papillotomy or fistulotomy with a needle-knife. The aim of this study was to assess the value of early application of the needle-knife in difficult biliary cannulation for endoscopic retrograde cholangiopancreatography (ERCP). METHODS: Patients with failed biliary cannulation after 10 minutes or guide wire entering the pancreatic tube 3 times were randomly divided into group of needle-knife cut and group of persistent cannulation by standard techniques. The cannulation times, success rates and complication rates were compared between the two groups. RESULTS: A total of 948 therapeutic biliary ERCP procedures were performed between October 2004 and February 2006. Of 91 patients with difficult biliary cannulation, 43 patients underwent needle-knife cut: the cannulation success rate was 90.7%, the mean cannulation time was 5.6 minutes, and the complication rate was 9.3%. The other 48 patients underwent persistent cannulation by standard techniques: the cannulation success rate was 75%, the mean cannulation time was 10.2 minutes, and the complication rate was 14.6%. Significant differences were observed in cannulation success rate and cannulation time but in complication rate between the two groups.CONCLUSION: The early application of the needle-knife in difficult biliary cannulation is time-saving, safe and effective, with no increase in complication rate.展开更多

However, scarce data are available on different precut techniques for difficult biliary cannulation. This study aimed to evaluate the efficacy and safety of transpancreatic septotomy(TPS), needle-knife fistulotomy(NKF) or both based on the presence of unintentional pancreatic access and papillary morphology. Methods: Between March 2008 and December 2016, 157 consecutive patients undergoing precutting for an inaccessible bile duct during ERCP were identified. Precut techniques were chosen depending on repetitive inadvertent pancreatic cannulation and the papillary morphology. We retrospectively assessed the rates of cannulation success and procedure-related complications among three groups, namely TPS, NKF, and TPS followed by NKF. Results: The baseline characteristics of the three groups were comparable. The overall success rate of biliary cannulation reached 98.1%, including 111 of 113(98.2%) with TPS, 35 of 36(97.2%) with NKF and 8 of 8(100%) with NKF following TPS, without significant difference among groups. The incidences of total complications and post-ERCP pancreatitis were 9.6% and 7.6%, respectively. There was a trend towards less frequent post-ERCP pancreatitis after NKF(0%) compared with 11 cases(9.7%) after TPS and one case(12.5%) after NKF following TPS, but not significantly different( P = 0.07). No severe adverse event occurred during this study period. Conclusions: The choice of precut techniques by the presence of unintended pancreatic access and the papillary morphology brought about a high success rate without increasing risk in difficult biliary cannulation.展开更多

Early NKF and DGT groups were assigned 67 patients each. In the DGT group, NKF was performed for an additional 7 min if successful cannulation was not achieved.RESULTS: The success rates with early NKF andthe DGT were 79.1%(53/67) and 44.8%(30/67)(P< 0.001), respectively. The incidence of post-ERCP pancreatitis(PEP) was lower in the early NKF group than in the DGT group [4.5%(3/67) vs 14.9%(10/67),P = 0.041]. The mean cannulation times in the early NKF and DGT groups after assignment were 257 s and312 s(P = 0.013), respectively.CONCLUSION: Our data suggest that early NKF should be considered as the first approach to selective biliary cannulation in patients with repetitive unintentional pancreatic cannulations.展开更多

A total of 104 cannulationsvia the minor papilla attempted in 74 patients at our center between January 2008 and June 2014 were retrospectively reviewed.RESULTS: Standard methods were successful in79 cannulations. Of the 25 cannulations that could not be performed by standard methods, 19 were performed by needle-knife, while 17(89.5%) were successful. Needle-knife use improved the success rate of cannulation [76.0%, 79/104 vs 92.3%,(79 +17)/104; P = 0.001]. When the 6 cases not appropriate for needle-knife cannulation were excluded, the success rate was improved further(80.6%, 79/98 vs98.0%, 96/98; P = 0.000). There were no significant differences in the rates of post-endoscopic retrograde cholangiopancreatography adverse events between the group using standard methods alone and the group using needle-knife after failure of standard methods(4.7% vs 10.5%, P = 0.301).CONCLUSION: The needle-knife procedure may be an alternative method for improving the success rate of cannulation via the minor papilla, particularly when standard cannulation has failed.展开更多

Methods: We searched the electronicdatabases from their inception to May 25, 2022, comprising Cochrane Library, PubMed,Embase, SinoMed, CNKI, VIP and Wanfang databases. Randomized controlled trials(RCTs) investigating the effectiveness of needle knives for people with primarydysmenorrhea were eligible. The risk of bias and the quality of the included literaturewere evaluated. RevMan5.3 software was used for this study. Results: Five articles with313 participants were involved in the review. The cure rate (2.82 (2.01, 3.95), I^(2) = 25%)and total effective rate (1.32 (1.10, 1.57), I^(2) = 65%) of the experimental group werehigher than those of the control group. The dysmenorrhea symptom scores (–1.81(–2.61, –1.01), I^(2) = 69%), TCM symptom scores (–4.19 (–6.06, –2.31), I2 = 0%) andadverse reactions (0.16 (0.05, 0.51), I^(2) = 0%) of the experimental group were lowerthan those of the control group. Conclusions: Needle knives may provide advantages inthe treatment of primary dysmenorrhea. RCTs, including the larger sample, multi-center,high-quality and double-blind research, were required to further verify the efficacy ofneedle knives for primary dysmenorrhea.展开更多

Methods: Needle-shaped knife was used for endoscop- ic sphincterotomy (EST) in 476 patients with biliary or pancreatic diseases from March 1995 to October 2000. Results: Direct incision was made in 243 patients, papillary fenestration in 89, and opposite incision in 144. The papilla located beside and in the diverticu- lum in 56 and 12 patients, respectively. EST emer- gency was made in 147 patients. ERCP after EST be- cause of the difficulty in intubation was made suc- cessfully in 62 patients. Mild complications occurred in 14 patients (2.94%), all of whom were cured af- ter symptomatic treatment. Conclusions: EST with needle-shaped knife has such advantages as safety in operation and convenience in incision. It is suitable for the papilla with different shape, with a higher success rate.展开更多

Applica- tion of various fungicides were evaluated in vivo at dif- ferent concentrations. However in both, mist-chamber and poly-chamber, the Blue pine （Pinus wallichiana Jackson） seedlings treated with hexaconazole 5EC （@ 0.03 %） or carbendazim 50WP （@ 0.1%） depicted significantly less disease incidence and intensity. The seedlings treated with mancozeb 75WP （@ 0.3 %） and chlorothalonil 75WP （@ 0.3 %） exhibited less disease incidence and intensity. Increase in relative humidity from 60 to 100 % signifi- cantly enhanced needle blight disease incidence and intensity. In field trial the fungitoxicants used either as single spray or protectant followed by systemic fungitoxi- cant spray significantly reduced disease incidence in Blue pine compared to check. The mean disease incidence in fungitoxicant treated plants varied from 11.82 to 25.51% as compared to 36.03 % in control.展开更多

文摘目的:探讨J型针刀通过PACAP-cAMP-PKA信号通路改善脊髓损伤后神经源性膀胱大鼠逼尿肌的作用机制。方法:36只SD雄性大鼠随机分为6组:空白组、假手术组、模型组、J型针刀治疗组、治疗+Bupivacaine抑制剂组、治疗+H-89抑制剂组,各6只。采用脊髓横断法制作神经源性膀胱模型。空白组为正常SD大鼠;假手术组为切开相关部位组织,无脊髓切断;其余4组予以手术脊髓切断造模。J型针刀治疗组造模后第19天予J型针刀针刺大鼠次髎穴,2 d 1次,共治疗7次。干预结束后各组行HE染色观察膀胱逼尿肌组织形态变化,Elisa检测膀胱逼尿肌组织中c AMP、PKA含量,免疫组化检测膀胱逼尿肌组织中PACAP38蛋白表达,Western blot检测膀胱逼尿肌组织中PKA、p-MLC蛋白表达。结果:HE染色结果显示,与空白组相比,模型组中膀胱逼尿肌组织严重坏死,可见大量炎症细胞浸润;与模型组相比,J型针刀治疗组、治疗+Bupivacaine抑制剂组及治疗+H-89抑制剂组均有不同程度坏死组织修复情况。免疫组化检测PACAP38蛋白表达在模型组中表达量最低,针刀治疗之后,PACAP38表达量均不同程度上调;与J型针刀治疗组相比,治疗+Bupivacaine抑制剂组及治疗+H-89抑制剂组PACAP38蛋白表达均不同程度下调(P<0.05),但高于模型组(P<0.05)。Elisa检测结果显示,cAMP、PKA表达量模型组显著下调(P<0.05),J型针刀治疗组与模型组比显著上调(P<0.05),治疗+Bupivacaine抑制剂组及治疗+H-89抑制剂组比无显著差异(P>0.05)。WB结果显示:与空白组相比,模型组PKA、p-MLC蛋白表达上调;针刀治疗组表达量下调,其中PKA蛋白表达有显著性(P<0.05),p-MLC蛋白表达无显著性(P>0.05)。与J型针刀治疗组比,PKA蛋白表达量在治疗+Bupivacaine抑制剂组及治疗+H-89抑制剂组中无显著差异(P>0.05),p-MLC蛋白表达量显著下降(P<0.05)。结论:J型针刀针刺次髎穴可改善脊髓损伤后神经源性膀胱大鼠膀胱功能,其机制与J型针刀上调膀胱逼尿肌中PACAP38、cAMP、PKA表达,激活PACAP-cAMP-PKA信号通路,从而促进逼尿肌舒张有关。
文摘AIM:To study the role of needle knife assisted ampullary biopsy in the diagnosis of periampullary carcinoma.METHODS:In this study the authors retrospectively analyzed clinical records of patients with periampullary tumors diagnosed by ampullary biopsy taken after needle knife papillotomy in whom surface ampullary biopsies were non contributory.RESULTS:Between January 2008 and December 2010,38 patients with periampullary tumors were seen by us and initial side viewing endoscopy with surface biopsy from the papilla was positive for malignancy in 25 patients.Thirteen patients with a negative surface biopsy for malignancy underwent a repeat ampullary biopsy following needle knife papillotomy.There were 8(61.5%)males and 5(38.5%)females.The most common presenting symptom was jaundice(100%),followed by fever(46.2%),melena(38.5%),abdominal pain(30.8%)and weight loss(30.8%).All the patients had hyperbilirubinemia with a mean ± SD serum bilirubin of(11.2 ± 1.9)mg/dL(normal value <1 mg%)and the mean ± SD serum alkaline phosphatase was(288.0 ± 94.3)IU/L(normal value < 129 IU/L).Serum CA 19.9 level estimation was done in 11 patients;it was elevated(cut off value > 70.5 IU/L)in all of them with a median of 1200 IU/L(inter quartile range 274-3500).Side viewing endoscopy showed a bulky papilla in all of them.Adequate tissue was obtained in all of the 13 patients for histological evaluation;12 of the 13 patients were reported to have adenocarcinoma while one patient had adenoma.There were no complications from the needle knife papillotomy in any of the patients.CONCLUSION:Needle knife assisted ampullary biopsy appears to be a safe and effective diagnostic modality for periampullary carcinoma.
文摘Objectives: To evaluate endoscopic duodenal sphinc- terotomy and improve its success rate. Methods: Needle-shaped knife was used for endoscop- ic sphincterotomy (EST) in 476 patients with biliary or pancreatic diseases from March 1995 to October 2000. Results: Direct incision was made in 243 patients, papillary fenestration in 89, and opposite incision in 144. The papilla located beside and in the diverticu- lum in 56 and 12 patients, respectively. EST emer- gency was made in 147 patients. ERCP after EST be- cause of the difficulty in intubation was made suc- cessfully in 62 patients. Mild complications occurred in 14 patients (2.94%), all of whom were cured af- ter symptomatic treatment. Conclusions: EST with needle-shaped knife has such advantages as safety in operation and convenience in incision. It is suitable for the papilla with different shape, with a higher success rate.
文摘AIM:To investigate the usefulness of a guide wire and triple lumen needle knife for removing stones in BillrothⅡ(B-Ⅱ)gastrectomy patients.METHODS:Endoscopic sphincterotomy in patients with B-Ⅱgastrectomy is challenging.We used a new guide wire technique involving sphincterotomy by triple lumen needle knife through a forward-viewing endoscopy.This technique was performed in nine patients between August 2010 and June 2012.Sphincterotomy as described above was performed.Adequate sphincterotomy,successful stone removal,and complications were investigated prospectively.RESULTS:Sphincterotomy by triple lumen needle knife using guide wire was successful in all nine patients.Sphincterotomy started towards the 4-5 o’clock direction and continued to the upper margin of the papillary roof.Complete stone removal in one session was achieved in all patients.There were no procedure related complications,such as bleeding,pancreatitis,or perforation.CONCLUSION:In patients with B-Ⅱgastrectomy,guide wire using sphincterotomy by triple lumen needle knife through a forward-viewing endoscopy seems to be an effective and safe procedure for the removal of common bile duct stones.

After 2-6 sessions of treatment, 23 cases (37.1%) were cured, 19 (30.7%) showed marked improvement, 15 (24.2%) had some improvement and 5 (8.1%) failed in the treatment. The total effective rate was 91.9%. It indicates that acupotomy therapy is a highly effective remedy for treating vertebral artery type cervical spndylopathy.
文摘Evaluation of various fungicides against needle blight disease of pine was carried out at Shed Kashmir University of Agriculture Sciences and Technology of Kashmir （India） during the year 2008 and 2009. Applica- tion of various fungicides were evaluated in vivo at dif- ferent concentrations. However in both, mist-chamber and poly-chamber, the Blue pine （Pinus wallichiana Jackson） seedlings treated with hexaconazole 5EC （@ 0.03 %） or carbendazim 50WP （@ 0.1%） depicted significantly less disease incidence and intensity. The seedlings treated with mancozeb 75WP （@ 0.3 %） and chlorothalonil 75WP （@ 0.3 %） exhibited less disease incidence and intensity. Increase in relative humidity from 60 to 100 % signifi- cantly enhanced needle blight disease incidence and intensity. In field trial the fungitoxicants used either as single spray or protectant followed by systemic fungitoxi- cant spray significantly reduced disease incidence in Blue pine compared to check. The mean disease incidence in fungitoxicant treated plants varied from 11.82 to 25.51% as compared to 36.03 % in control.
