BD-IPMN growth rates ≥2 mm/year and total growth of ≥10 mm should be considered worrisome features for BD-IPMN at increased risk of malignancy.

BackgroundUsing commercially available television and movies is a potentially effective tool to foster humanistic, compassionate and person-centred orientations in medical students.AimWe reviewed pedagogical applications of television and movies in medical education to explore whether and why this innovation holds promise.MethodsWe performed a literature review to provide a narrative summary on this topic.ResultsFurther studies are needed with richer descriptions of innovations and more rigorous research designs.ConclusionAs we move toward evidence-informed education, we need an evidence- based examination of this topic that will move it beyond a ‘show and tell’ discussion toward meaningful implementation and evaluation. Further exploration regarding the theoretical basis for using television and movies in medical education will help substantiate continued efforts to use these media as teaching tools.Electronic supplementary materialThe online version of this article (doi: 10.1007/s40037-015-0205-9) contains supplementary material, which is available to authorized users.

This article has an accompanying continuing medical education activity, also eligible for MOC credit, on page e67. Learning Objective-Upon completion of this activity, successful learners should be able to understand the prevalence of pancreatic cysts in clinical practice and determine the prognosis of asymptomatic pancreatic cysts. BACKGROUND & AIMS: The 2015 American Gastroenterological Association guidelines recommend discontinuation of surveillance of pancreatic cysts after 5 years, although there are limited data to support this recommendation. We aimed to determine the rate of pancreatic cancer development from neoplastic pancreatic cysts after 5 years of surveillance. METHODS: We performed a retrospective multicenter study, collecting data from 310 patients with asymptomatic suspected neoplastic pancreatic cysts, identified by endoscopic ultrasound from January 2002 to June 2010 at 4 medical centers in California. All patients were followed up for 5 years or more (median, 87 mo; range, 60-189 mo). Data were used to calculate the risk for pancreatic cancer and all-cause mortality. RESULTS: Three patients (1%) developed invasive pancreatic adenocarcinoma. Based on American Gastroenterological Association high-risk features (cyst size > 3 cm, dilated pancreatic duct, mural nodule), risks for cancer were 0%, 1%, and 15% for patients with 0, 1, or 2 high-risk features, respectively. Mortality from nonpancreatic causes was 8-fold higher than mortality from pancreatic cancer after more than 5 years of surveillance. CONCLUSIONS: There is a very low risk of malignant transformation of asymptomatic neoplastic pancreatic cysts after 5 years. Patients with pancreatic lesions and 0 or 1 high-risk feature have a less than 1% risk of developing pancreatic cancer, therefore discontinuation of surveillance can be considered for select patients. Patients with neoplastic pancreatic cysts with 2 high-risk features have a 15% risk of subsequent pancreatic cancer, therefore surgery or continued surveillance should be considered.

Background Type II achalasia (Ach2) is distinguished from other achalasia sub‐types by the presence of panesophageal pressurization (PEP) of ≥30 mmHg in ≥20% swallows on high‐resolution manometry (HRM). Variable manometric features in Ach2 have been observed, characterized by focal elevated pressures (FEPs) (focal/segmental pressures ≥70 mmHg within the PEP band) and/or high compression pressures (PEP ≥70 mmHg). This study aimed to examine clinical and physiologic variables among sub‐groups of Ach2. Methods This retrospective single center study performed over 3 years (1/2019–1/2022) included adults with Ach2 on HRM who underwent endoscopic ultrasound (EUS), functional lumen imaging probe (FLIP), and/or barium esophagram (BE) prior to therapy. Patients were categorized into two overarching sub‐groups: Ach2 without FEPs and Ach2 with FEPs. Demographic, clinical, and physiologic data were compared between these sub‐groups utilizing unpaired univariate analyses. Key Results Of 53 patients with Ach2, 40 (75%) were without FEPs and 13 (25%) had FEPs. Compared with the Ach2 sub‐group without FEPs, the Ach2 sub‐group with FEPs demonstrated a significantly thickened distal esophageal circular muscle on EUS (1.4 mm [SD 0.9] vs. 2.1 [0.7]; p = 0.02), higher prevalence of tertiary contractions on BE (46% vs. 100%; p = 0.0006), lower esophagogastric junction distensibility index (2.2mm2/mmHg [0.9] vs 0.9 [0.4]; p = 0.0008) as well as higher distensive pressure (31.0 mmHg [9.8] vs. 55.4 [18.8]; p = 0.01) at 60 cc fill on FLIP, and higher prevalence of chest pain on Eckardt score (p = 0.03). Conclusions and Inferences We identified a distinct sub‐group of type II achalasia on HRM, defined as type II achalasia with focal elevated pressures. This sub‐group uniquely exhibits spastic features and may benefit from personalized treatment approaches.
