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.

The aim of this study is to report and analyze the results of a questionnaire concerning the present programs for the junior residents in the postgraduate clinical course in Japan.
A questionnaire was sent to the administrators or the persons in charge of the programs of 347 institutions including 80 university hospitals and 267 clinical training hospitalsas designated by the Ministry of Health and Welfare.
Answers to a questionnaire were returned by 271 institutions (78.1%). The results were analyzed and summarized as follows.
(1) About 95% of both university and clinical training hospitals have their own programs at present.
(2) In the substantial formula of programs, university hospitals have had straight or rotation form while the clinical hospitals have selected rotation or super rotate (comprehensive) form.
(3) The programs of university hospitals have started in majority before 1992 while those of clinical hospitals have began after 1993.
(4) The programs of university hospitals have contained the clinical training at the other departments or institutions in a significantly higher ratio compared to those of clinical hospitals.
(5) The check system for the evaluation of the programs has well functioned in half of both hospitals.
(6) For the assessment of the programs used, about half of the staffs of both university and clinical hospitals feel unsatisfactorily in their active programs.
(7) Concerning the intention to renewal or modification of their programs used, there were rather passive agreements in both university and clinical hospitals.

This paper proposes a method for evaluating and scoring the activities of rehabilitation service users in order to pinpoint the problems with the health service of this kind and set the adequate targets for each user. Sincs the Nursing Care Insurance System was introduced in Japan in 2000, it has been argued that home-visit rehabilitation services should be excluded from home-nursing care services. However, the methods of certifing that nursing care is required are not fully established yet for setting the rehabilitation targets for service users. As things stand, it is recommended that such a method as the Functional Independence Measure (FIM) or the Barthel Index (BI) should be utilized. However, these methods only evaluate “performing activities” (the activities that a user usually performs). In order to set the users' targets, we thought it necessary to establish a method for evaluating “possible activities” (the activities that a user is able to perform at his/her full capacity). We have established a method called Functional Scoring (FS) which evaluates and scores the both performing and possible activities based on the same evaluation items. We conducted experimental evaluations on the home-visit rehabilitation users for one year from October 2005 to September 2006. When the first evaluations in 2005 were compared with the second evaluations in 2006, the total score of the performing activities significantly increased from 44.1±13.7 to 47.8±14.2 (P<0.05). Although the total score of the possible activities did not significantly increase, it demonstrated an upward trend from 49.6±13.2 to 51.6±13.5. The result suggests that our method is useful for distinguishing between the performing and possible activities. The proposed method enables us to adequately recognize the problems each user has, and to set the rehabilitation target for each user, which can be shared between the user, care personnel, and care service provider.

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.

Adenocarcinoma currently accounts for 10–25% of all uterine cervical carcinomas and has a variety of histopathological subtypes. Among them, mucinous carcinoma gastric type is not associated with high-risk human papillomavirus (HPV) infection and a poor prognosis, while villoglandular carcinoma has an association with high-risk HPV infection and a good prognosis. They show relatively characteristic imaging findings which can be suggested by magnetic resonance imaging (MRI), though the former is sometimes difficult to be distinguished from lobular endocervical glandular hyperplasia. Various kinds of other tumors including squamous cell carcinoma should be also differentiated on MRI, while it is currently difficult to distinguish them on MRI, and HPV screening and pathological confirmation are usually necessary for definite diagnosis and further patient management.

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.

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.

Clinical Endoscopy 2023;56(3):353-366
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.
