Biography

Overview

Dr. Aziz Merchant's clinical expertise and areas of interest include minimally
invasive
surgical techniques, anti-reflux and hiatal hernia surgery, esophageal surgery and
Achalasia, laparoscopic hernia repair, Bariatric surgery and obesity, and complex
revisional laparoscopy. His research interests include surgical outcomes, patient-
centered outcomes, surgical quality improvement, and cost-effectiveness research.
From and
educational perspective, Dr. Merchant’s interests include surgical residency training
and
surgical simulation.

Dr. Merchant currently serves as a committee member for Research, Publications, and
Bariatrics committees of the Society of American Gastrointestinal and Endoscopic
Surgeons.
He is an active member of the American College of Surgeons, the American Society for
Metabolic and Bariatric Surgery, and the Association of Academic Surgery.

Dr. Merchant completed medical school at Thomas Jefferson University in Philadelphia,
followed by surgical residency at Georgetown University. Then he finished a
fellowship in
advanced laparoscopy and bariatric surgery at Emory University. Prior to arriving at
Rutgers,
he was an assistant professor and associate residency program director at Central
Michigan
University, where he was part of a team that established a Bariatric Surgery program
at their
affiliate, St. Mary's of Michigan.

Current Research

The effects of health disparity and obesity on the presentation of abdominal wall hernias

Inguinal hernia is one of the most common surgical diagnoses encountered by the surgeon and
non-surgeon alike, and its repair is one of the most commonly performed general surgical
procedures. Elective repair is safer than emergent surgery for incarceration, strangulation,
bowel obstruction or bowel ischemia. Initial presentation, whether reducible, incarcerated, or
strangulated, can depend upon ethnic background, payer status, and obesity, and certain
subgroups of patients with inguinal hernia may be more likely to be admitted to the emergency
room with incarceration or strangulation as their initial presentation. These emergent
situations confer a higher morbidity and mortality then elective repair. Indeed, in a study
investigating risk factors for recurrence after umbilical hernia repair, race was found to be
contributing factor to recurrence . Moreover, in a study looking the effect of patient and
hospital factors in ventral hernia outcomes, payer status and patient ethnicity was a risk
factor for poor outcomes and higher morbidity.

Obesity, considered by many to be part of the realm of health disparity, has long been proven
to be a risk factor for poor hernia outcomes. In addition, obesity prevalence is known to be
higher among the uninsured, underinsured, and health disparate population. Put together,
uninsured and underinsured patients, with poor access to primary and surgical care and weight
loss options, may be at risk for poor outcomes from one of the most common surgical diagnoses
and procedures. These poor outcomes may be preventable if this at-risk population can be
identified, offered timely weight loss and surgical management, and offered appropriate
follow-up.

Improving overall outcomes in hernia repair and decreasing emergent presentations to the
emergency room for inguinal hernia patients may be linked to improving health disparities in
different patient populations. The first step in this solution is to identify and quantify
the problem. The goals of this project are as follows:


Aim 1:
To use a reliable, high-volume, administrative database of university hospital data, the
University HealthSystem Consortium, to investigate the following important questions:

1. Are differences in inguinal hernia repair outcomes related to race and
socioeconomic/insurance status?
a. Are these differences related to patient overweight or obesity?

2. Do these differences account for a disproportionate number of emergent inguinal hernia
presentations in health disparate and obese populations?

3. What are specific, modifiable risk factors in health disparate populations for poor
outcomes after inguinal hernia repair?

a. Is obesity one of these modifiable risk factors?
