Predictive factors for the necessity of peroral cholangioscopy-guided lithotripsy in the endoscopic treatment of cystic duct confluence stones: a retrospective study in Japan: Kazuaki Miyamoto, Takahisa Ogawa, Shinsuke Koshita, Yoshihide Kanno, Hiroaki Kusunose, Toshitaka Sakai, Keisuke Yonamine, Fumisato Kozakai, Haruka Okano, Yuto Matsuoka, Kento Hosokawa, Hidehito Sumiya, Kei Ito; Clin Endosc 2026;59(2):280-287. Published online January 9, 2026; DOI: https://doi.org/10.5946/ce.2025.195

Background
/Aims: The treatment of cystic duct confluence stones often requires peroral cholangioscopy (POCS)-guided lithotripsy. This study evaluated the efficacy of endoscopic treatment for cystic duct confluence stones and identified predictive factors for the need for POCS-guided lithotripsy.
Methods
This retrospective cohort study included 38 patients with cystic duct confluence stones treated endoscopically between September 2007 and December 2023. The primary outcome was the rate of complete stone removal. Secondary outcomes included the number of sessions, total procedure time, adverse events, and predictive factors for POCS-guided lithotripsy.
Results
The complete stone removal rate was 100%. POCS-guided lithotripsy was required in 50% of the cases. The mean number of sessions needed for stone removal was 2.05. The mean procedure time was 93.9 minutes. The incidence of adverse events was 13%. Multivariate analysis showed that a minor axis length of the stone relative to the distal bile duct diameter greater than 1.2 was an independent predictive factor for requiring POCS-guided lithotripsy.
Conclusions
Endoscopic treatment is highly effective for cystic duct confluence stones. However, POCS-guided lithotripsy was necessary when the minor axis of the stone relative to the distal bile duct diameter exceeded 1.2.

Efficacy of double half-pigtail plastic stents for endoscopic biliary drainage of acute calculous cholangitis: Toshitaka Sakai, Yoshihide Kanno, Shinsuke Koshita, Takahisa Ogawa, Hiroaki Kusunose, Keisuke Yonamine, Kazuaki Miyamoto, Fumisato Kozakai, Haruka Okano, Kento Hosokawa, Hidehito Sumiya, Jun Horaguchi, Masaya Oikawa, Takashi Tsuchiya, Yutaka Noda, Kei Ito; Clin Endosc 2025;58(6):898-908. Published online November 11, 2025; DOI: https://doi.org/10.5946/ce.2025.134

Graphical Abstract Abstract PDF

Background
/Aims: Plastic stent placement is required when biliary stones cannot be completely removed during the initial endoscopic retrograde cholangiopancreatography (ERCP). Although double half-pigtail plastic stents (DHPs) help prevent stent migration, their clinical utility has not yet been evaluated.
Methods
We retrospectively reviewed data from 221 patients who underwent DHP placement for acute calculous cholangitis (ACC) between January 2015 and March 2024. Patient without complete stone removal during initial ERCP were included. Clinical success, adverse events, recurrent biliary obstruction (RBO), and time to RBO (TRBO) were compared in 21 patients treated with straight plastic stents (STs) under similar conditions.
Results
Clinical success was achieved in 99% of patients in the DHP group and 95% of the ST group (p=0.13). Adverse event rates were comparable between groups. During follow-up, the DHP group had significantly lower stent occlusion (2% vs. 20%, p<0.01) and migration rates (4% vs. 15%, p=0.02), leading to a lower RBO rate (5% vs. 35%, p<0.01). The median TRBO was significantly longer in the DHP group (585 vs. 247 days, p<0.01).
Conclusions
DHPs had comparable efficacy to STs, with significantly fewer stent-related adverse events. This may be a potential option for biliary drainage in ACC.

Incidence and risk factors for recurrence of common bile duct stones in patients undergoing endoscopic extraction without prophylactic biliary stenting and subsequent cholecystectomy: a retrospective study in Japan: Hidehito Sumiya, Takahisa Ogawa, Shinsuke Koshita, Yoshihide Kanno, Hiroaki Kusunose, Toshitaka Sakai, Keisuke Yonamine, Kazuaki Miyamoto, Fumisato Kozakai, Haruka Okano, Yuto Matsuoka, Kento Hosokawa, Kei Ito; Clin Endosc 2026;59(1):124-131. Published online October 24, 2025; DOI: https://doi.org/10.5946/ce.2025.081

Graphical Abstract Abstract PDF

Background
/Aims: In patients undergoing endoscopic extraction of common bile duct stones (CBDs) and subsequent cholecystectomy, CBDs sometimes recur during the preoperative and perioperative periods. In this study, the incidence and risk factors for CBDs recurrence were investigated.
Methods
A total of 245 patients (mean age: 66 years; 138 men) who underwent cholecystectomy within 180 days of CBDs extraction between October 2017 and June 2023 were included. Recurrence was defined as the detection of the CBDs during the preoperative or perioperative period using imaging modalities such as computed tomography or re-endoscopic retrograde cholangiopancreatography, regardless of the presence of cholangitis.
Results
CBDs recurrence occurred in 4.1% of the patients (10/245). The median time to recurrence was 40 days. Preoperative recurrence was observed in nine patients, and only one patient had postoperative recurrence. Multivariate analysis identified cystic duct stones as the only significant risk factor for CBDs recurrence (hazard ratio, 15.6; 95% confidence interval, 3.7–66; p<0.001).
Conclusions
The risk of CBDs recurrence after endoscopic extraction during the pre and perioperative periods is high in patients with cystic duct stones. Prophylactic biliary stenting may be considered in high-risk patients.

Predictive factors for the diagnosis of autoimmune pancreatitis using endoscopic ultrasound-guided tissue acquisition: a retrospective study in Japan: Keisuke Yonamine, Shinsuke Koshita, Yoshihide Kanno, Takahisa Ogawa, Hiroaki Kusunose, Toshitaka Sakai, Kazuaki Miyamoto, Fumisato Kozakai, Haruka Okano, Yuto Matsuoka, Kento Hosokawa, Hidehito Sumiya, Yutaka Noda, Kei Ito; Clin Endosc 2025;58(3):457-464. Published online March 28, 2025; DOI: https://doi.org/10.5946/ce.2024.238

Graphical Abstract Abstract PDF

Background
/Aims: The factors affecting the detection rate of lymphoplasmacytic sclerosing pancreatitis (LPSP) using endoscopic ultrasound-guided tissue acquisition (EUS-TA) in patients with type 1 autoimmune pancreatitis (AIP) have not been thoroughly studied. Therefore, we conducted a retrospective study to identify the predictive factors for histologically detecting level 1 or 2 LPSP using EUS-TA.
Methods
Fifty patients with AIP were included in this study, and the primary outcome measures were the predictive factors for histologically detecting level 1 or 2 LPSP using EUS-TA.
Results
Multivariate analysis identified the use of fine needle biopsy (FNB) needles as a significant predictive factor for LPSP detection (odds ratio, 15.1; 95% confidence interval, 1.62–141; ¬¬p=0.017). The rate of good-quality specimens (specimen adequacy score ≥4) was significantly higher for the FNB needle group than for the fine needle aspiration (FNA) needle group (97% vs. 56%; p<0.01), and the FNB needle group required significantly fewer needle passes than the FNA needle group (median, 2 vs. 3; p<0.01).
Conclusions
The use of FNB needles was the most important factor for the histological confirmation of LPSP using EUS-TA in patients with type 1 AIP.

Prophylactic endoscopic transpapillary gallbladder stenting to prevent acute cholecystitis induced after metallic stent placement for malignant biliary strictures: a retrospective study in Japan: Fumisato Kozakai, Yoshihide Kanno, Shinsuke Koshita, Takahisa Ogawa, Hiroaki Kusunose, Toshitaka Sakai, Keisuke Yonamine, Kazuaki Miyamoto, Haruka Okano, Yuto Matsuoka, Kento Hosokawa, Hidehito Sumiya, Kei Ito; Clin Endosc 2024;57(5):647-655. Published online May 17, 2024; DOI: https://doi.org/10.5946/ce.2023.284

Graphical Abstract Abstract PDF

Background
/Aims: Endoscopic biliary drainage using self-expandable metallic stents (SEMSs) for malignant biliary strictures occasionally induces acute cholecystitis (AC). This study evaluated the efficacy of prophylactic gallbladder stents (GBS) during SEMS placement.
Methods
Among 158 patients who underwent SEMS placement for malignant biliary strictures between January 2018 and March 2023, 30 patients who attempted to undergo prophylactic GBS placement before SEMS placement were included.
Results
Technical success was achieved in 21 cases (70.0%). The mean diameter of the cystic duct was more significant in the successful cases (6.5 mm vs. 3.7 mm, p<0.05). Adverse events occurred for 7 patients (23.3%: acute pancreatitis in 7; non-obstructive cholangitis in 1; perforation of the cystic duct in 1 with an overlap), all of which improved with conservative treatment. No patients developed AC when the GBS placement was successful, whereas 25 of the 128 patients (19.5%) without a prophylactic GBS developed AC during the median follow-up period of 357 days (p=0.043). In the multivariable analysis, GBS placement was a significant factor in preventing AC (hazard ratio, 0.61; 95% confidence interval, 0.37–0.99; p=0.045).
Conclusions
GBS may contribute to the prevention of AC after SEMS placement for malignant biliary strictures.

Diagnostic value of homogenous delayed enhancement in contrast-enhanced computed tomography images and endoscopic ultrasound-guided tissue acquisition for patients with focal autoimmune pancreatitis: Keisuke Yonamine, Shinsuke Koshita, Yoshihide Kanno, Takahisa Ogawa, Hiroaki Kusunose, Toshitaka Sakai, Kazuaki Miyamoto, Fumisato Kozakai, Hideyuki Anan, Haruka Okano, Masaya Oikawa, Takashi Tsuchiya, Takashi Sawai, Yutaka Noda, Kei Ito; Clin Endosc 2023;56(4):510-520. Published online April 5, 2023; DOI: https://doi.org/10.5946/ce.2022.142

Graphical Abstract Abstract PDF

Background
/Aims: We aimed to investigate (1) promising clinical findings for the recognition of focal type autoimmune pancreatitis (FAIP) and (2) the impact of endoscopic ultrasound (EUS)-guided tissue acquisition (EUS-TA) on the diagnosis of FAIP.
Methods
Twenty-three patients with FAIP were involved in this study, and 44 patients with resected pancreatic ductal adenocarcinoma (PDAC) were included in the control group.
Results
(1) Multivariate analysis revealed that homogeneous delayed enhancement on contrast-enhanced computed tomography was a significant factor indicative of FAIP compared to PDAC (90% vs. 7%, p=0.015). (2) For 13 of 17 FAIP patients (76.5%) who underwent EUS-TA, EUS-TA aided the diagnostic confirmation of AIPs, and only one patient (5.9%) was found to have AIP after surgery. On the other hand, of the six patients who did not undergo EUS-TA, three (50.0%) underwent surgery for pancreatic lesions.
Conclusions
Homogeneous delayed enhancement on contrast-enhanced computed tomography was the most useful clinical factor for discriminating FAIPs from PDACs. EUS-TA is mandatory for diagnostic confirmation of FAIP lesions and can contribute to a reduction in the rate of unnecessary surgery for patients with FAIP.

Pancreatic duct lavage cytology combined with a cell-block method for patients with possible pancreatic ductal adenocarcinomas, including pancreatic carcinoma in situ: Hiroaki Kusunose, Shinsuke Koshita, Yoshihide Kanno, Takahisa Ogawa, Toshitaka Sakai, Keisuke Yonamine, Kazuaki Miyamoto, Fumisato Kozakai, Hideyuki Anan, Kazuki Endo, Haruka Okano, Masaya Oikawa, Takashi Tsuchiya, Takashi Sawai, Yutaka Noda, Kei Ito; Clin Endosc 2023;56(3):353-366. Published online November 16, 2022; DOI: https://doi.org/10.5946/ce.2022.021

Graphical Abstract Abstract PDF

Background
/Aims: This study aimed to clarify the efficacy and safety of pancreatic duct lavage cytology combined with a cell-block method (PLC-CB) for possible pancreatic ductal adenocarcinomas (PDACs).
Methods
This study included 41 patients with suspected PDACs who underwent PLC-CB mainly because they were unfit for undergoing endoscopic ultrasonography-guided fine needle aspiration. A 6-Fr double lumen catheter was mainly used to perform PLC-CB. Final diagnoses were obtained from the findings of resected specimens or clinical outcomes during surveillance after PLC-CB.
Results
Histocytological evaluations using PLC-CB were performed in 87.8% (36/41) of the patients. For 31 of the 36 patients, final diagnoses (invasive PDAC, 12; pancreatic carcinoma in situ, 5; benignancy, 14) were made, and the remaining five patients were excluded due to lack of surveillance periods after PLC-CB. For 31 patients, the sensitivity, specificity, and accuracy of PLC-CB for detecting malignancy were 94.1%, 100%, and 96.8%, respectively. In addition, they were 87.5%, 100%, and 94.1%, respectively, in 17 patients without pancreatic masses detectable using endoscopic ultrasonography. Four patients developed postprocedural pancreatitis, which improved with conservative therapy.
Conclusions
PLC-CB has an excellent ability to detect malignancies in patients with possible PDACs, including pancreatic carcinoma in situ.

Endoscopic Interventions for the Early and Remission Phases of Acute Biliary Pancreatitis: What are the More Concrete and Practical Situations for Performing Them?: Sho Hasegawa, Shinsuke Koshita, Yoshihide Kanno, Takahisa Ogawa, Toshitaka Sakai, Hiroaki Kusunose, Kensuke Kubota, Atsushi Nakajima, Yutaka Noda, Kei Ito; Clin Endosc 2021;54(6):888-898. Published online May 27, 2021; DOI: https://doi.org/10.5946/ce.2020.271

Abstract PDF: Background
/Aims: The use of endoscopic intervention (EI) for acute biliary pancreatitis (ABP) remains controversial because the severity of biliary obstruction/cholangitis/pancreatitis is not reflected in the indications for early EI (EEI).
Methods
A total of 148 patients with ABP were included to investigate 1) the differences in the rate of worsening cholangitis/pancreatitis between the EEI group and the early conservative management (ECM) group, especially for each severity of cholangitis/pancreatitis, and 2) the diagnostic ability of imaging studies, including endoscopic ultrasound (EUS), to detect common bile duct stones (CBDSs) in the ECM group.
Results
No differences were observed in the rate of worsening cholangitis between the EEI and ECM groups, regardless of the severity of cholangitis and/or the existence of impacted CBDSs. Among patients without impacted CBDSs and moderate/severe cholangitis, worsening pancreatitis was significantly more frequent in the EEI group (18% vs. 4%, p=0.048). In patients in the ECM group, the sensitivity and specificity for detecting CBDSs were 73% and 98%, respectively, for EUS, whereas the values were 13% and 92%, respectively, for magnetic resonance cholangiopancreatography.
Conclusions
EEI should be avoided in the absence of moderate/severe cholangitis and/or impacted CBDSs because of the high rate of worsening pancreatitis. EUS can contribute to the accurate detection of residual CBDSs, for the determination of the need for elective EI.

Safety and Recipient Satisfaction of Propofol Sedation in Outpatient Endoscopy: A 24-Hour Prospective Investigation Using a Questionnaire Survey: Yoshihide Kanno, Tetsuya Ohira, Yoshihiro Harada, Shinsuke Koshita, Takahisa Ogawa, Hiroaki Kusunose, Yoshiki Koike, Taku Yamagata, Toshitaka Sakai, Kaori Masu, Keisuke Yonamine, Kazuaki Miyamoto, Megumi Tanaka, Tomohiro Shimada, Fumisato Kozakai, Kazuki Endo, Haruka Okano, Daichi Komabayashi, Takeshi Shimizu, Shohei Suzuki, Kei Ito; Clin Endosc 2021;54(3):340-347. Published online December 11, 2020; DOI: https://doi.org/10.5946/ce.2020.138

Abstract PDF

Background
/Aims: The aim of this study was to evaluate the safety of sedation with propofol as an alternative to benzodiazepine drugs in outpatient endoscopy.
Methods
In this prospective study, examinees who underwent outpatient endoscopy under propofol sedation and submitted a nextday questionnaire with providing informed consent were evaluated. Periprocedural acute responses, late adverse events within 24 hours, and examinee satisfaction were evaluated.
Results
Among the 4,122 patients who received propofol in the 17,978 outpatient-based endoscopic examinations performed between November 2016 and March 2018, 2,305 eligible examinees (esophagogastroduodenoscopy for 1,340, endoscopic ultrasonography for 945, and total colonoscopy for 20) were enrolled, and their responses to a questionnaire were analyzed. The mean propofol dose was 69.6±24.4 mg (range, 20–200 mg). Diazepam, midazolam, and/or pentazocine in combination with propofol was administered to 146 examinees. Mild oxygen desaturation was observed in 59 examinees (2.6%); and mild bradycardia, in 2 (0.09%). Other severe reactions or late events did not occur. After eliminating 181 invalid responses, 97.7% (2,065/2,124) of the patients desired propofol sedation in future examinations.
Conclusions
Propofol sedation was found to be safe—without severe adverse events or accidents—for outpatient endoscopy on the basis of the patients’ next-day self-evaluation. Given the high satisfaction level, propofol sedation might be an ideal tool for painless endoscopic screening.

Inside Plastic Stents versus Metal Stents for Treating Unresectable Malignant Perihilar Biliary Obstructions: A Retrospective Comparative Study: Yoshihide Kanno, Shinsuke Koshita, Takahisa Ogawa, Hiroaki Kusunose, Kaori Masu, Toshitaka Sakai, Keisuke Yonamine, Kazuaki Miyamoto, Toji Murabayashi, Fumisato Kozakai, Jun Horaguchi, Yutaka Noda, Kei Ito; Clin Endosc 2020;53(6):735-742. Published online March 4, 2020; DOI: https://doi.org/10.5946/ce.2020.003

Abstract PDF

Background
/Aims: The aim of this study was to evaluate outcomes of inside plastic stents (iPSs) versus those of metal stents (MSs) for treating unresectable perihilar malignant obstructions.
Methods
For all patients who underwent endoscopic suprapapillary placement of iPS(s) or MS(s) as the first permanent biliary drainage for unresectable malignant perihilar obstructions between January 2014 and August 2019, clinical outcomes using iPSs (n=20) and MSs (n=85), including clinical efficacy, adverse events, and time to recurrence of biliary obstruction (RBO), were retrospectively evaluated.
Results
There were no differences in clinical effectiveness (95% for the iPS group vs. 92% for the MS group, p=1.00). Procedure-related adverse events, including pancreatitis, acute cholangitis, acute cholecystitis, and death, were observed for 8% of the MS group, although no patient in the iPS group developed such adverse events. The median time to RBO was 561 days (95% confidence interval, 0–1,186 days) for iPSs and 209 days (127–291 days) for MSs, showing a significant difference (p=0.008).
Conclusions
Time to RBO after iPS placement was significantly longer than that after MS placement. IPSs, which are removable, unlike MSs, were an acceptable option.

Predictive Value of Localized Stenosis of the Main Pancreatic Duct for Early Detection of Pancreatic Cancer: Yoshihide Kanno, Shinsuke Koshita, Takahisa Ogawa, Hiroaki Kusunose, Kaori Masu, Toshitaka Sakai, Keisuke Yonamine, Yujiro Kawakami, Yuki Fujii, Kazuaki Miyamoto, Toji Murabayashi, Fumisato Kozakai, Jun Horaguchi, Yutaka Noda, Masaya Oikawa, Takaho Okada, Kei Ito; Clin Endosc 2019;52(6):588-597. Published online November 20, 2019; DOI: https://doi.org/10.5946/ce.2019.018

Abstract PDF

Background
/Aims: In this study, we aimed to evaluate the predictive value of localized stenosis of the main pancreatic duct (MPD) for early detection of pancreatic cancer.
Methods
Among 689 patients who underwent endoscopic retrograde pancreatography from January 2008 to September 2018, 19 patients with MPD findings were enrolled. These patients showed findings for indicating suspicious pancreatic cancer at an early stage (FiCE); FiCE was defined as a single, localized stenosis in the MPD without a detectable mass (using any other imaging methods) and without other pancreatic diseases, such as definite chronic pancreatitis, intraductal papillary mucinous neoplasm, and autoimmune pancreatitis. Final diagnoses were established by examining resected specimens or through follow-up examinations after an interval of >5 years.
Results
Among 19 patients with FiCE, 11 underwent surgical resection and 8 were evaluated after a >5-year observation period. The final diagnosis of the MPD stenosis was judged to be pancreatic cancer in 9 patients (47%), including 3 with intraepithelial cancer, and to be a non-neoplastic change in 10. The sensitivity, specificity, and accuracy of preoperative pancreatic juice cytology were 75%, 100%, and 88%, respectively.
Conclusions
The predictive value of FiCE for pancreatic cancer prevalence was 47%. Histological confirmation with pancreatic juice cytology is necessary before surgical resection.

Endoscopic Ultrasonography-Guided Gallbladder Drainage as a Treatment Option for Acute Cholecystitis after Metal Stent Placement in Malignant Biliary Strictures: Fumisato Kozakai, Yoshihide Kanno, Kei Ito, Shinsuke Koshita, Takahisa Ogawa, Hiroaki Kusunose, Kaori Masu, Toshitaka Sakai, Toji Murabayashi, Keisuke Yonamine, Yujiro Kawakami, Yuki Fujii, Kazuaki Miyamoto, Yutaka Noda; Clin Endosc 2019;52(3):262-268. Published online March 15, 2019; DOI: https://doi.org/10.5946/ce.2018.183

Abstract PDF

Background
/Aims: It is often difficult to manage acute cholecystitis after metal stent (MS) placement in unresectable malignant biliary strictures. The aim of this study was to evaluate the feasibility of endoscopic ultrasonography-guided gallbladder drainage (EUS-GBD) for acute cholecystitis.
Methods
The clinical outcomes of 10 patients who underwent EUS-GBD for acute cholecystitis after MS placement between January 2011 and August 2018 were retrospectively evaluated. The procedural outcomes of percutaneous transhepatic gallbladder drainage (PTGBD) with tube placement (n=11 cases) and aspiration (PTGBA) (n=27 cases) during the study period were evaluated as a reference.
Results
The technical success and clinical effectiveness rates of EUS-GBD were 90% (9/10) and 89% (8/9), respectively. Severe bile leakage that required surgical treatment occurred in one case. Acute cholecystitis recurred after stent dislocation in 38% (3/8) of the cases. Both PTGBD and PTGBA were technically successful in all cases without severe adverse events and clinically effective in 91% and 63% of the cases, respectively.
Conclusions
EUS-GBD after MS placement was a feasible option for treating acute cholecystitis. However, it was a rescue technique following the established percutaneous intervention in the current setting because of the immature technical methodology, including dedicated devices, which need further development.

Predictive Factors for Inaccurate Diagnosis of Swollen Lymph Nodes in Endoscopic Ultrasound-Guided Fine Needle Aspiration: Yuki Fujii, Yoshihide Kanno, Shinsuke Koshita, Takahisa Ogawa, Hiroaki Kusunose, Kaori Masu, Toshitaka Sakai, Keisuke Yonamine, Yujiro Kawakami, Toji Murabayashi, Fumisato Kozakai, Yutaka Noda, Hiroyuki Okada, Kei Ito; Clin Endosc 2019;52(2):152-158.

Abstract PDF

Background
/Aims: This study aimed to identify the predictive factors for inaccurate endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) diagnosis of swollen lymph nodes without rapid on-site cytopathological evaluation.
Methods
Eighty-three consecutive patients who underwent EUS-FNA for abdominal or mediastinal lymph nodes from January 2008 to June 2017 were included from a prospectively maintained EUS-FNA database and retrospectively reviewed. The sensitivity, specificity, and accuracy of EUS-FNA for the detection of neoplastic diseases were calculated. Candidate factors for inaccurate diagnosis (lymph node size and location, needle type, puncture route, number of passes, and causative disease) were evaluated by comparison between accurately diagnosed cases and others.
Results
The final diagnosis of the punctured lymph node was classified as neoplastic (65 cases: a metastatic lymph node, malignant lymphoma, or Crow-Fukase syndrome) or non-neoplastic (18 cases: a reactive node or amyloidosis). The sensitivity, specificity, and accuracy were 83%, 94%, and 86%, respectively. On multivariate analyses, small size of the lymph node was the sole predictive factor for inaccurate EUS-FNA diagnosis with a significant difference (odds ratios, 19.8; 95% confidence intervals, 3.15–124; p=0.0015).
Conclusions
The lymph node size of <16 mm was the only independent factor associated with inaccurate EUS-FNA diagnosis of swollen lymph nodes.

Abstract PDF

Background
/Aims: Although both radial- and convex-arrayed endoscopic ultrasonography (EUS) scopes are widely used for observational EUS examinations, there have been few comparative studies on their power of visualization. The aim of this study was to evaluate the capability of these EUS scopes for observation of the pancreatobiliary junction.
Methods
The rate of successful visualization of the pancreatobiliary junction was retrospectively compared between a radial-arrayed and a convex-arrayed echoendoscope, from a prospectively maintained database. Study periods were defined as January 2010 to December 2012 for the radial group, and February 2015 to October 2016 for the convex group because the respective scope was mainly used during those periods.
Results
During the study period, 1,660 cases with radial EUS and 1,984 cases with convex EUS were recruited. The success rates of observation of the pancreatobiliary junction were 80.0% and 89.5%, respectively (p<0.0001).
Conclusions
The capability of visualization of the pancreatobiliary junction in observational EUS was found to be better with a convex-arrayed than with a radial-arrayed echoendoscope.
