Dr. Najjia Mahmoud is an Associate Professor, and the Chief of the Division of Colon and Rectal Surgery in the Department of Surgery.  Dr. Mahmoud received her B.S. from the University of Wisconsin and her M.D. from the Weill College of Medicine at Cornell.  She completed General Surgery Residency at Columbia-Presbyterian Hospital and then her Fellowship in Colon and Rectal Surgery at the University of Minnesota.  Dr. Mahmoud served briefly on the faculty at Thomas Jefferson University School of Medicine before joining the faculty at the University of Pennsylvania as Assistant Professor in 2002.  She was promoted to in 2009. 

She has a particular interest in sphincter-saving procedures for rectal cancer, endorectal ultrasound, and in the treatment and diagnosis of inherited forms of colorectal cancer. She also specializes in surgery for pelvic floor disorders such as incontinence, rectocele, enterocele, and rectal prolapse. Colonoscopy, both diagnostic and therapeutic, and laparoscopic approaches to colorectal disease are part of her practice. Research efforts focus on the impact of colorectal cancer genetics on treatment and evaluation of novel chemoprevention agents for colorectal cancer.

Research
 
Current Research
Colorectal Cancer Surgery Outcomes: Colorectal cancer is the third leading cause of cancer mortality in the US. Surgery is currently the only known treatment resulting in cure of this disease. Examination of outcomes of surgery for colorectal cancer is the focus of current research efforts.
 
Rectal Cancer Database
(institutional—University of Pennsylvania)
  • Efforts center on defining optimal neoadjuvant treatment in advanced stage rectal cancer with increased sphincter preservation and morbidity the primary endpoints.
  • Use of this prospectively maintained database to define factors influencing medical and surgical outcomes in rectal cancers by age, race, and gender based on treatment and tumor stage.
SEER-Medicare Database. Use of a national database linked to Medicare files to better understand and identify trends in the outcomes of the medical and surgical care and treatment of colorectal cancer patients.
  • Define differences in care based upon treatment location/institutional variations.
  • Examine how differences in presentation of colorectal cancer impacts upon disease-free and overall survival.
  • Investigate ways in which trends in treatment of colorectal cancer diffuse through the US.
  • Explore how widely adopted “quality measures” such as lymph node harvest influence and change the surgical treatment of colon and rectal cancer.
Clinical Trials: The Division of Colon and Rectal Surgery is committed to ongoing efforts to improve perioperative care and long-term outcomes in the surgical treatment of colorectal disease through clinical trials.
  • 2004 Investigator Adolor Protocol 14CL314: A Multicenter, Phase III, Double-Blind, Placebo-Controlled Parallel Study of ADL 8-2698 in Opioid Induced Postoperative Bowel Dysfunction/Postoperative Ileus (closed).
