Background and Objectives:
The benefits of rapid on-site evaluation (ROSE) of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) of solid masses have not been convincingly shown in large, randomized trials. New equipment using EUS-guided fine needle biopsy (FNB) allows for more material to be acquired that may obviate the need for ROSE. This study aimed to evaluate if EUS-FNB without ROSE was non-inferior to EUS-FNA with ROSE in solid pancreatic masses (SPMs).
Methods:
Patients with SPMs requiring tissue sampling were randomly assigned to undergo either EUS-FNA with ROSE or EUS-FNB without ROSE. The touch-imprint cytology technique was used to perform ROSE. The primary endpoint was diagnostic accuracy and secondary endpoints were specimen quality, complication rates, and procedure time.
Results:
Seventy-eight patients were randomized and analyzed (39 EUS-FNA with ROSE and 39 EUS-FNB without
ROSE). Non-significantly different diagnostic accuracies were noted in both groups (97% with ROSE and 100%
without ROSE, P < 0.371). The bloodiness of histologic samples and complication rates were not significantly different between groups. A significantly shorter mean sampling procedural time was noted for EUS-FNB over EUS-FNA with ROSE (30.4 ± 10.4 vs 35.8 ± 9.8 minutes, P < .02).
Conclusions
EUS-FNB demonstrated equal diagnostic accuracy with shorter procedure times in evaluating SPMs compared to EUS-FNA with ROSE. These new-generation FNB needles may obviate the need for ROSE.

We report the case of a patient with hypoglycemic symptoms and weight gain. Biochemical investigations revealed endogenous hyperinsulinemic hypoglycemia. A CT scan and MRI of the abdomen were initially not successful in localizing a pancreatic mass. However, an endoscopic ultrasound was able to demonstrate a pancreatic head mass. Enucleation of the mass resulted in clinical and biochemical improvement. This report also demonstrates the pattern of weight loss after surgery, showing an initial phase of gradual weight loss followed by a rapid loss of weight. This pattern of weight loss after successful removal of an insulin-producing pancreatic neuroendocrine tumor is a novel addition to the existing knowledge we have about this condition.

Rationale. COVID-19 pandemic disease, can be transmitted during gastrointestinal procedures, via aerosolized droplets, and via fecal shedding. Both international and local endoscopy societies have issued strategies to alleviate the risk to endoscopy personnel. However, several barriers against the implementation of these recommendations exist thus individual center’s policies are employed whenever applicable.
Objectives. This narrative study aims to describe the current experience and set-up in the endoscopy unit of a COVID referral center, discuss the stratification of patients for endoscopy, the operational management of the personnel and endoscopy unit in line with the adapted local and international guidelines and offer endoscopists a quick reference guide to adapt endoscopy practice during the pandemic in a resource-limited setting.
Methodology. This paper reviews and consolidates current endoscopy guidelines and describes the single-center experience of Philippine General Hospital.
Results. In resource-limited settings, with uncertainties of prolonged COVID-19 impact to healthcare, modification of practice, adherence to strategies and recommendations, empowerment of workforce, establishing the sustainability of resources, training, and service to patients, are essential components to combat current dilemma brought about by this pandemic.
Conclusion. Integration of current local and international guidelines encompass all aspects of endoscopy practice during the pandemic. The recommendations cited are aimed to guide other resource-limited endoscopy units for potential changes and guidance in the overall practice.
