Segmental Atrophy Of The Liver: Review Of A Rare Pseudotumor, Ayesha Younus, Yu Liu, Ellen E. Connor, Zeng-Ying Wu, Hwajeong Lee, Zhi-Yan Fu

School of Medicine Faculty Publications

Segmental atrophy (SA) of the liver is a rare, often underrecognized, benign condition that presents as a mass lesion, mimicking a neoplasm, which poses a significant diagnostic challenge. Given its rarity, only a limited number of case reports and series have been published, resulting in sparse literature on the entity. This review aims to summarize the clinicopathologic and diagnostic features of SA and thus improve its recognition.

Early Recurrent Midgut Volvulus Post Ladd's Procedure In A Newborn: A Case Report, Nicole Clarke, Joanna Sajdlowska, John Paul Bustamante, Nishith Bhattacharyya

Rowan-Virtua School of Osteopathic Medicine Departmental Research

Ladd's procedure is the standard surgical intervention for intestinal malrotation. Although generally curative, rare cases of early postoperative complications, including adhesions or recurrent volvulus, can necessitate reoperation. We present the case of a full-term newborn girl who underwent emergent Ladd's procedure on Day 3 of life for malrotation with volvulus. She was discharged on postoperative Day 17 but returned the following day with recurrent bilious emesis. Imaging suggested partial obstruction. Exploratory laparotomy revealed recurrent volvulus with two twists at the duodenojejunal junction, which was successfully reduced. The patient recovered well and was discharged on postoperative Day 8. This case underscores …

Case Report: A Severe Case Of Post-Operative Ogilvie Syndrome Requiring Surgical Intervention, Aashna A. Chaudhry

Rowan-Virtua Research Day

Ogilvie Syndrome is an acute colonic pseudo-obstruction described as a paralysis of the colon with no real mechanical obstruction. This condition is oftentimes a benign post-surgical complication but can progress in severity if not treated appropriately. This case report presents a unique clinical case in which an adult female patient developed a severe case of Ogilvie syndrome postoperatively requiring surgical intervention.

Case Report: Petersen Hernia, A Rare Cause Of Bowel Ischemia, Brian Lim, Dhara Patel, Adeshola Fakulujo, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

We report a case of a 52-year-old female with history Roux-en-Y gastric bypass (RYGB) three years ago prior to presentation to the emergency department (ED) with sudden onset epigastric abdominal pain with radiation into the back of two hours duration. She was diagnosed with bowel ischemia due to internal hernia through a Petersen’s mesenteric defect. A Petersen’s mesenteric defect is one of the three possible internal hernia sites and occurs between the Roux limb mesentery and a defect in the transverse mesocolon.

Abdominal complaints are common in the emergency department with wide differential ranging from benign to emergent with need …

The Gut Microbiome And Knee Osteoarthritis: A Review Of Emerging Pathophysiologic Links, Krisha S. Patel, Maduka Gunasinghe, Umer Shah, Kushkumar K. Patel, Zarif Ladak

Rowan-Virtua Research Day

Background

Knee osteoarthritis (OA), a multifactorial degenerative joint disease with growing prevalence in aging and obese populations, leads to disabling pain. Traditionally viewed as mechanically driven, increasing research implicates systemic inflammation and metabolic and neuroimmune modulation. The gut microbiome—an ecosystem of commensal organisms regulating host immune, metabolic, and inflammatory regulation—has emerged as a potential contributor to OA pathogenesis and symptom severity. This review aims to synthesize literature evaluating associations between gut microbiota composition and knee OA, focusing on inflammatory pathways, pain modulation, and emerging therapies.

Methods

A literature search was conducted using PubMed, Embase, Scopus, and Web of Science. Inclusion …

Effects Of Social Isolation On Cecum Opioid Receptor Expression And Affective Behavior, Jordan Riser, John Tkaczynski, Nicole Shellenbarger, Maya Patel, Daniel Chandler, Daniel Manvich

Rowan-Virtua Research Day

BACKGROUND

Psychological stress can induce gastrointestinal symptoms and exacerbate existing gastrointestinal disorders, indicating an interaction between the central and enteric nervous systems. Central nervous system activation of opioid receptors stimulates sympathetic outflow to the enteric nervous system, delaying motility and reducing gastrointestinal secretions, producing a similar clinical presentation to IBS.

HYPOTHESIS

We hypothesize that social isolation induces anxiety states, disrupting homeostatic noradrenergic activity in the brain and gut, leading to neurophysiological changes in the cecum characterized by altered expression of opioid receptors.

METHODS

Sprague-Dawley rats were housed in either group (control) or socially isolated conditions. Affective behavior was assessed using …

Aortoduodenal Syndrome: A Rare Case Of Duodenal Obstruction Due To Endovascular Aneurysm Endoleak., Raksha Adhikari, Parth Patel, Christopher Tait

Rowan-Virtua School of Osteopathic Medicine Departmental Research

Aortoduodenal syndrome results from expansion of an abdominal aortic aneurysm, leading to symptoms of upper gastrointestinal obstruction. Endovascular aneurysm repair of large or symptomatic aortic aneurysms has become an important treatment modality for patients with abdominal aortic aneurysm. However, a large proportion of these grafts are complicated by endoleaks that can lead to a spectrum of significant symptoms. We present a case of rapidly worsening gastrointestinal obstructive symptoms in a patient with an already repaired aortic stent graft and a solitary kidney, found to be due to a type III endoleak that improved after emergent repeat endovascular aneurysm repair.

Bilio-Cecal Stent Migration Presenting As Massive Rectal Bleeding., Lefika Bathobakae, Shady Geris, Mohita Jariwala, Mansi Patel, Jessica Escobar, Ruhin Yuridullah, Kamal Amer, Yana Cavanagh

Rowan-Virtua School of Osteopathic Medicine Departmental Research

Endoscopic biliary stenting is a well-established intervention for the treatment of biliary, hepatic, and pancreatic disorders. The common indications include strictures, neoplasms, stones, infections, and bile leaks. Stents can be occluded, predisposing patients to ascending cholangitis and biliary sepsis. Distal stent migration is another known complication of endoscopic stenting and is usually spontaneous. Bowel perforation, abscesses, bleeding, and pancreatitis are rare complications of distal stent migration and are usually limited to the duodenum. Herein, we describe an extremely rare case of bilio-cecal stent migration presenting as rectal bleeding.

Clinical Outcomes For Patients With Nafld And Acute Hepatitis: An Analysis Of The National Inpatient Sample, Dakota B. Pastore, Tony Elias, Peter Senatore

Rowan-Virtua Research Day

Introduction: Non-alcoholic fatty liver disease (NAFLD) is the most common form of chronic liver disease in the United States and has been found to play a significant role in cardiovascular disease risk through several mechanisms including dyslipidemia, insulin resistance, coagulability, and inflammation. Acute-on-chronic liver disease continues to contribute to worse health outcomes via acute hepatitis.

Methods: This case-control study investigated the relationship between NAFLD and acute hepatitis using data extracted from the National Inpatient Sample (NIS) Database for the years 2019 and 2020. The NIS was searched for hospitalizations of adult patients with acute hepatitis with and without NAFLD. Using …

Sigmoid Perforation Extending Into The Abdominal Wall, Zamran Masih, Wayne Tamaska, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

Sigmoid colon perforation and spread into the abdominal wall is a rare condition that can occur due to various causes such as diverticulitis, trauma, malignancy, or iatrogenic injury during surgery. Although rare, sigmoid colon perforation into the abdominal wall can result in significant morbidity and mortality if not promptly diagnosed and treated. Most common cause of diverticular disease leading to perforation is diverticulitis, accounting for 60% of all colonic perforations.

Perforating Gastric/Duodenal Ulcer Development Following Roux-En-Y Gastric Bypass Surgery: A Case Series, Sugosh Anur, Michael A. Coscia Iii, Louis Balsama

Rowan-Virtua Research Day

Roux-en-Y gastric bypass is a well-studied procedure resulting in long term weight loss. Due to countless years of study, the morbidity and mortality associated with a Roux en Y gastric bypass has been greatly decreased. However, there are still several rare, yet serious, complications that may arise in the post-operative period. Anastomotic leaks and ulcers are just two of those complications. We describe a case of a 41 year old female developing postoperative perforated duodenal ulcer. A laparoscopic repair was performed using a Graham patch technique. This review aims to identify factors contributing to the ulcer development as well as …

Appendiceal Diverticulum Masquerading As Acute Appendicitis, Aesha Patel, Asad Abbas, Ratul Bhattacharyya, Dana Galaktionova

Rowan-Virtua Research Day

Appendiceal diverticula present as rare clinical findings and are most often confused with acute appendicitis due to similar presentation. The incidence in such cases is reported at a rate no greater than 1%.

We present a rare case of a 65-year-old female treated for acute appendicitis who was instead found to have acute sequelae of appendiceal diverticulosis.

A Gut Feeling: A Hypothesis Of The Role Of The Microbiome In Attention-Deficit/Hyperactivity Disorders., Xue Ming, Neil Chen, Carly Ray, Gretchen Brewer, Jeffrey Kornitzer, Robert A Steer

Rowan-Virtua School of Osteopathic Medicine Departmental Research

Attention-deficit/hyperactivity disorder (ADHD) is a neurologic disorder characterized by hyperactivity/impulsivity and/or inattentiveness, with genetic and environmental factors contributing to the disorder. With the growing recognition of the microbiome's role in many neurological disorders, the authors propose that it may also be implicated in ADHD. Here, we describe several evolving areas of research to support this hypothesis. First, a unique composition of gut bacteria has been identified and linked to behaviors in ADHD. Second, our research found an increased incidence of 2 gastrointestinal symptoms (constipation and flatulence) in children with ADHD, as compared to controls. Finally, emerging data may be interpreted …
