Transition To Noninvasive Testing From The Gold Standard Of Liver Biopsy, Heidi Bien, Sabina Choudhry, Christine Pocha, University Of South Dakota Sanford School Of Medicine & Avera Health System

Scholarship Pathways Program

Purpose: Metabolic dysfunction–associated steatotic liver disease (MASLD), formerly known as non-alcoholic fatty liver disease, represents a rapidly growing public health concern, affecting roughly 30% of the global population. MASLD encompasses a spectrum from simple steatosis to its more progressive form, metabolic dysfunction–associated steatohepatitis (MASH). Early and accurate assessment of liver disease is critical for risk stratification and management, yet the current gold standard-liver biopsy remains invasive, costly, and limited by sampling variability and interpretive subjectivity. Noninvasive imaging modalities, particularly magnetic resonance elastography (MRE), have emerged as promising alternatives, but their concordance with biopsy in real-world clinical practice remains underexplored.

An Unusual Source Of A Lethal Pathogen: Paeniclostridium Sordellii Bacteremia In Acute Cholecystitis, Myrna Garcia, Leena Algarin, Olutoyin Abitoye, Rachel Gnanaprakasam

North Texas GME Research Forum 2026

Paeniclostridium sordellii is a spore-forming, gram-positive, anaerobic bacilli known for its highly virulent toxin production, often leading to fulminant sepsis and shock. It is most commonly associated with gynecologic infections and necrotizing soft tissue infections associated with intravenous drug use. However, reports of P. sordellii bacteremia in the setting of gall bladder infections are quite rare. This case report highlights an unusual presentation of P. sordellii infection with bloodstream infection originating from acute cholecystitis, demonstrating a non-fulminant clinical course and successful treatment with ceftriaxone.

Ashwagandha-Associated Liver Injury: A Systematic Literature Review, David Teplitsky, Jacob Sebaugh, Danielle Ford, Rashid Syed

North Texas GME Research Forum 2026

Background: Ashwagandha (Withania somnifera), an herb with origins in Ayurvedic medicine, has recently grown in global popularity due to its reported stress- and anxiety-relieving properties. While generally regarded as safe, emerging cases in medical literature have raised concern for its ability to cause drug- or herb-induced liver injury (DILI/HILI). As use of this supplement rises, it is particularly important to characterize ashwagandha’s potential hepatotoxicity.

Methods: Cases of ashwagandha-induced liver injury were collected by accessing PubMed, Europe PMC, Google Scholar, and the HCA Healthcare Library and searching combinations of the terms “liver” or “hepatic” and one of the following names for …

Salvage Percutaneous Spyglass-Assisted Lithotripsy Via A Cholecystostomy Tract After Failed Ercp: A Case Report, Nicholas Gerden, Tiffany Hong, Asad Rehman, Long Hoang

North Texas GME Research Forum 2026

IR-driven percutaneous cholangioscopy with SpyGlass-assisted lithotripsy is an emerging salvage technique for biliary stone disease in patients with failed or contraindicated endoscopic retrograde cholangiopancreatography (ERCP) due to complex anatomy. We report an 85-year-old patient with an indwelling cholecystostomy tube and biliary stent who presented with recurrent obstructive jaundice, with cholangiography demonstrating occlusion of the common bile duct stent due to choledocholithiasis. Conventional ERCP was unsuccessful because of complex biliary and gastrointestinal anatomy. A multidisciplinary interventional radiology–gastroenterology approach was therefore pursued, utilizing antegrade percutaneous choledochoscopy through an existing cholecystostomy tract with SpyGlass-assisted lithotripsy, followed by cholecystostomy tube exchange. The procedure resulted …

Robotic Cholecystectomy With Choledochoscopy After Failed Ercp: A Case Report, James Zhang, Ethan Pavlovsky, Jennifer Austin, Furrukh Jabbar, Hassan Ahmed

North Texas GME Research Forum 2026

Background: In the United States, there are an estimated 20 million cases of cholelithiasis, though a majority remain asymptomatic. Development of choledocholithiasis is seen in 10%-20% of those with cholelithiasis. Typically, choledocholithiasis is managed via a two-stage approach starting with endoscopic retrograde cholangiopancreatography (ERCP) followed by laparoscopic cholecystectomy on the same admission. More recent trends have seen a shift towards surgeon-directed management of the common bile duct through one-stage procedures that combine cholecystectomy with intraoperative common bile duct (CBD) exploration using choledochoscopy. We present a case of chronic choledocholithiasis with large, impacted gallstones that was managed with robotic cholecystectomy, choledochotomy, …

Extra-Intestinal Clostridioides Difficile Abscess In A Small Bowel Gist: A Rare Tumor-Associated Complication, Nicholas Gerden, Pradip Gautam, Asad Rehman, Long Hoang

North Texas GME Research Forum 2026

Extra-intestinal infections caused by Clostridioides difficile are exceedingly rare and typically occur in settings that disrupt the gastrointestinal barrier, including recent gastrointestinal surgery, bowel perforation or microperforation, and severe colonic disease.

We present the case of a 75-year-old man with abdominal pain and hemoperitoneum in the setting of a suspected small bowel leak secondary to an intestinal mass. Computed tomography angiography revealed an 11.0 × 9.6 cm pelvic fluid collection, prompting exploratory laparotomy with drainage of a pelvic abscess and evacuation of hemoperitoneum. Intraoperatively, a small bowel perforation caused by a 4.4 cm gastrointestinal stromal tumor (GIST) was identified. Operative …
