Challenges in Diagnosis: Primary Hepatic Lymphoma Presenting as a Space-Occupying Liver Lesion.

Non-Hodgkin lymphoma is a heterogeneous group of lymphoid neoplasms, the incidence of which has increased over the past 3 decades. Primary non-Hodgkin lymphoma of the liver is a very rare malignancy. We outline a case describing primary hepatic lymphoma in an 85-year-old woman with a history of breast cancer who presented with generalized weakness and nonspecific symptoms.

Gastric Electric Stimulation for Refractory Gastroparesis: A Prospective Analysis of 151 Patients at a Single Center.

Background: Gastric electric stimulation (GES) is used to treat patients with refractory gastroparesis symptoms. However, the effectiveness of GES in clinical practice and the effect of GES on specific symptoms of gastroparesis are not well delineated.

Aims: To determine the effectiveness of GES for treatment for refractory symptoms of gastroparesis, the improvement in specific symptoms of gastroparesis, and clinical factors impacting on outcome.

Hemosuccus Pancreaticus: A Mysterious Cause of Gastrointestinal Bleeding.

Hemosuccus pancreaticus (bleeding from the pancreatic duct into the gastrointestinal tract via the ampulla of Vater) is a rare, potentially life-threatening and obscure cause of upper gastrointestinal bleeding. It is caused by rupture of the psuedoaneurysm of a peripancreatic vessel into pancreatic duct or pancreatic psuedocyst in the context of pancreatitis or pancreatic tumors. It can pose a significant diagnostic and therapeutic dilemma due to its anatomical location and that bleeding into the duodenum is intermittent and cannot be easily diagnosed by endoscopy.

Surgical outcomes after gastric electric stimulator placement for refractory gastroparesis.

Background: Gastric electric stimulation (GES) is used for refractory gastroparesis symptoms. Although symptomatic improvement has been reported with GES, few studies describe the need for additional surgery after placement. Our goal was to evaluate the outcomes of a large series of GES at a single institution.

Small intestinal bacterial overgrowth in gastroparesis.

Objective: To determine symptoms of small intestinal bacterial overgrowth (SIBO) in gastroparesis patients.

Methods: Patients undergoing LBT (lactulose breath test) for evaluation of SIBO were included. LBT was considered positive on the basis of three conventional criteria: (1) hydrogen level increase >20 ppm above baseline by 90 min (H2@90min); (2) dual hydrogen peaks (>10 ppm increase over baseline before second peak >20 ppm (DPHBT); and (3) breath methane increase of >20 ppm above baseline by 90 min.

The impact of functional constipation on quality of life of middle-aged Black Americans: a prospective case-control study.

Purpose: To quantify the impact of constipation on health-related quality of life (HRQoL) in Black Americans.

Methods: Case-control design. Black subjects referred for colon cancer screening with a Bristol Stool Score of 3-5 for >75% of bowel movements served as controls.

Prevalence and distribution of adenomas in black Americans undergoing colorectal cancer screening.

Background: The American College of Gastroenterology recommends colorectal cancer (CRC) screening for average-risk black Americans ages 45-49. This is based on this group's younger age for the development of adenomas and CRC. Our purpose was to determine the yield of CRC screening in average-risk black Americans including those View Article and Find Full Text PDF
