A Large Sigmoid Pseudo-Pedunculated Lipoma Mimicking an Adenoma: A Report of a Rare Case and Literature Review.

Large colonic lipomas exceeding 2.0 cm in size may rarely mimic colorectal adenomas and hence we referred to such lipomas as pseudo-pedunculated lipomas. They can exhibit surface erosions, fissure ulcerations, and mucosal erythema and can pose diagnostic dilemmas during colonoscopy.

Role of artificial intelligence (Google bard) in morphological, histopathological, and radiological image identifications: Objective Structured Practical Examination (OSPE) type-based performance.

Objectives: To evaluate the role of artificial intelligence (Google Bard) in figures, scans, and image identifications and interpretations in medical education and healthcare sciences through an Objective Structured Practical Examination (OSPE) type of performance.

Methods: The OSPE type of question bank was created with a pool of medical sciences figures, scans, and images. For assessment, 60 figures, scans and images were selected and entered into the given area of the Google Bard to evaluate the knowledge level.

The Scientific Knowledge of Bard and ChatGPT in Endocrinology, Diabetes, and Diabetes Technology: Multiple-Choice Questions Examination-Based Performance.

Background: The present study aimed to investigate the knowledge level of Bard and ChatGPT in the areas of endocrinology, diabetes, and diabetes technology through a multiple-choice question (MCQ) examination format.

Methods: Initially, a 100-MCQ bank was established based on MCQs in endocrinology, diabetes, and diabetes technology. The MCQs were created from physiology, medical textbooks, and academic examination pools in the areas of endocrinology, diabetes, and diabetes technology and academic examination pools.

Ultrastructural study of the gastric mucosa and Helicobacter pylori in duodenal ulcer patients.

Objective: To investigate the relationship between Helicobacter pylori and gastric mucosa in control and duodenal ulcer patients at the electron microscopic level.

Methods: Three antral biopsies were taken from each of 20 normal control volunteers and 30 duodenal ulcer patients presented to the gastroenterology unit at Jordan University Hospital for upper endoscopic examination. Each specimen was fixed and processed for electron microscopic study.

A comparative ultrastructural study of the Helicobacter pylori in duodenal ulcer patients before and after treatment.

The role of endoscopic retrograde cholangiopancreatography in small children and adolescents.

Diagnostic and therapeutic endoscopic retrograde cholangiopancreatography (ERCP) was performed on 16 patients aged 2 months to 18 years at Jordan University Hospital in the period between May 1990 to January 1993. The adult side-viewing duodenoscope was used, and visualization of appropriate ductal system was accomplished in 100% of the cases with no complications. Intravenous sedation was used in 69% of the cases with diazepam and pethidine (meperidine).

Endoscopic removal of retained common bile duct stones in patients with T tube in situ.

Endoscopic sphincterotomy (ES) was performed on 27 patients after cholecystectomy with a T tube in situ at a mean interval of 23 days after surgery. A precut papillotomy facilitated deep cannulation and subsequent standard ES in three patients with impacted ampullary stones. Bile duct clearance was successful at the first attempt in 22 of 25 (88%) patients who had common bile duct stones.

Ketamine hydrochloride as sole anesthetic for open liver biopsy.

We evaluated the use of ketamine as sole anesthetic agent for open liver biopsy, with particular reference to its effect on liver function and hepatotoxicity and its effect on cardiovascular stability and respiration. From 386 patients who underwent liver biopsy at Jordan University Hospital, 12 had open liver biopsy because of contra-indications for closed needle biopsy. The surgical procedure consisted of a small right paramedian incision allowing inspection of the liver surface and a wedge and needle biopsy.
