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.

Application of needle-knife in difficult biliary cannulation for endoscopic retrograde cholangiopancreatography

BACKGROUND: Getting directly into the common bile duct (CBD) is the most important step for successful therapeutic biliary endoscopy. 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.

Comparison of efficacy and safety of transpancreatic septotomy, needle-knife fistulotomy or both based on biliary cannulation unintentional pancreatic access and papillary morphology

Background: Precut sphincterotomy has been widely performed to facilitate selective biliary access when standard cannulation attempts failed during endoscopic retrograde cholangiopancreatography(ERCP). 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.

Needle-knife fistulotomy vs double-guidewire technique in patients with repetitive unintentional pancreatic cannulations

AIM: To compare the success rates and adverse events of early needle-knife fistulotomy(NKF) and double-guidewire technique(DGT) in patients with repetitive unintentional pancreatic cannulations.METHODS: From a total of 1650 patients admitted for diagnostic or therapeutic endoscopic retrograde cholangiopancreatography(ERCP) at a single tertiary care hospital(Pusan National University Yangsan Hospital, Yangsan, South Korea) between January2009 and December 2012, 134(8.1%) patients with unsuccessful biliary cannulation after 5 min trial of conventional methods, together with 5 or more repetitive unintentional pancreatic cannulations, were enrolled in the study. 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.

Endoscopic treatment for pancreatic diseases:Needle-knife-guided cannulation via the minor papilla

AIM: To determine the efficacy and safety of meticulous cannulation by needle-knife.METHODS: Three needle-knife procedures were used to facilitate cannulation in cases when standard cannulation techniques failed. 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.

Needle knife in the treatment of primary dysmenorrhea: a systematic review and meta-analysis

Objective: The aim of this meta-analysis was to examine the effectiveness and safety ofneedle knives for primary dysmenorrhea. 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.

Management of needle blight (Lophodermium pinastri) disease in Blue pine trees in Kashmir,India

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.

基于经筋理论的膝骨关节炎患者“筋结点”超声解剖学特征分析与针刀治疗的疗效评价研究

目的:借助可视化肌骨超声深入剖析膝骨关节炎患者膝关节局部经筋病灶点的病理特征,并综合评价弓弦平衡针刀法与常规针刺法治疗膝骨关节炎的疗效差异,为今后针刀精准辨位定点及安全入路研究提供客观参考依据。方法:将120例膝骨关节炎患者随机分为针刀治疗组和针刺对照组,每组60例。针刀治疗组进行弓弦平衡针刀法治疗,每周2次;针刺对照组选取犊鼻、内膝眼、阳陵泉、梁丘、鹤顶,及局部阿是穴进行针刺,同时根据不同的证型进行配穴加减,每周3次。2组均以3周为1个疗程,治疗3个疗程。根据肌骨超声下“筋结点”的精确定位、层次解剖、回声特点深入剖析经筋病灶点的超声影像学特征,采用股直肌羽状角、肌纤维横断面积、西安大略和麦克马斯特大学骨关节炎指数(WOMAC)评分、白细胞介素-1β(IL-1β)、肿瘤坏死因子-α(TNF-α)综合评价2组疗效差异。结果:治疗后,2组患者WOMAC评分、股直肌羽状角、平均肌纤维厚度、弹性应变率、IL-1β、TNF-α水平,及膝关节疼痛程度、僵硬、日常活动能力方面较治疗前均显著改善(P <0.05);其中,针刀治疗组在提升股直肌羽状角、增加肌纤维厚度、降低弹性应变率、降低致炎致痛因子水平方面优于针刺对照组,差异有统计学意义(P <0.05);与正常膝关节超声解剖结构相比,患者膝关节各针刀松解点(筋结点)处呈现出不同程度回声增强,同时伴有滑膜增厚、增生、关节腔积液、滑囊积液等典型超声影像学特征。结论:肌骨超声能够精准呈现膝骨关节炎患者膝关节经筋病灶点的解剖位置、解剖层次等超声病变特征,证实弓弦平衡针刀法的安全性和有效性,为针刀医学的标准化、规范化研究提供重要参考依据。
