EUS-guided management of anastomotic stricture: A case report.

Introduction And Importance: Anastomotic stenosis after low anterior resection is a serious complication and at times even requires surgical revision of the anastomosis.

Case Presentation And Clinical Discussion: The patient presented with a 4.0 cm tubulovillous adenoma of the proximal rectum and underwent low anterior resection with loop ileostomy and subsequent reversal.

Initial evaluation of a novel, prototype, forward-viewing echoendoscope in a porcine arterial bleeding model (with video).

Background: Real-time visualization of submucosal arterial flow at the base of an ulcer might improve endoscopic hemostasis by permitting more accurate assessment of the artery, precise targeting of therapy, and confirmation of vessel ablation.

Objective: To evaluate the utility of a novel, forward-viewing echoendoscope in identifying bleeding submucosal arteries, guiding hemostatic therapy, and confirming cessation of flow through treated vessels.

Design: In 7 pigs, a previously described porcine model for peptic ulcer hemorrhage was created by isolating the gastroepiploic and/or short gastric artery and tunneling it into the subserosal space at laparotomy.

Variability in measurements of pancreatic cyst size among EUS, CT, and magnetic resonance imaging modalities.

Background: Cyst size is an important factor in the management of pancreatic cysts, both in predicting the need for surgery and the frequency of follow-up.

Objective: To determine agreement and precision of EUS, CT, and magnetic resonance imaging (MRI) modalities in the evaluation of pancreatic cyst diameter.

Design: Retrospective chart review.

Characterization of pancreatic cancer and intra-abdominal lymph node malignancy using spectrum analysis of endoscopic ultrasound imaging.

This study assessed the ability of spectral analysis of endoscopic ultrasound (EUS) RF signals acquired in humans in vivo to distinguish between (1) benign and malignant intraabdominal and mediastinal lymph nodes and (2) pancreatic cancer, chronic pancreatitis, and normal pancreas. Mean midband fit, slope, intercept, and correlation coefficient from a linear regression of the calibrated RF power spectra were computed over regions of interest defined by the endoscopist. Linear discriminant analysis was then performed to develop a classification of the resulting spectral parameters.

In vivo characterization of pancreatic and lymph node tissue by using EUS spectrum analysis: a validation study.

Background: Quantitative spectral analysis of the radiofrequency (RF) signals that underlie grayscale EUS images can be used to provide additional, objective information about tissue state.

Objective: Our purpose was to validate RF spectral analysis as a method to distinguish between (1) benign and malignant lymph nodes and (2) normal pancreas, chronic pancreatitis, and pancreatic cancer.

Design And Setting: A prospective validation study of eligible patients was conducted to compare with pilot study RF data.

Are large side holes associated with reduced rates of pancreatic stent occlusion? Results of a prospective study.

Context: Pancreatic stents are frequently clogged at the time of removal. There is limited data regarding the factors associated with stent occlusion.

Objectives: To estimate the frequency of stent occlusion at the time of removal, to study the accuracy of endoscopic prediction of occlusion, and to determine the factors associated with clogged pancreatic stents.

Two men with toxic shock syndrome presenting with targetoid and spotty skin rashes.

Two previously healthy men who presented with hypotension, constitutional symptoms, and targetoid and discrete spotty erythematous plaques were diagnosed with toxic shock syndrome based on histopathological findings. Specifically, their biopsies revealed necrotic keratinocytes, neutrophils in the epidermis, and neutrophils surrounding dilated superficial vessels. In one case, the diagnosis of toxic shock syndrome was confirmed with rising titers to toxic shock syndrome toxin-1.
