Cleveland Clinic Colon and Rectal Surgeon, Daniel Geisler, MD, Joins West Penn Allegheny Health System

Friday, May 20th, 2011

Dr. Geisler pioneered least-invasive technique for colorectal surgery

PITTSBURGH (May 18, 2011) – Dan Geisler, MD, a nationally recognized colon and rectal surgeon from the Cleveland Clinic, has joined West Penn Allegheny Health System.
Among his many accomplishments, Dr. Geisler pioneered single-port colorectal surgery and is one of just a few surgeons in the country performing this procedure. It is currently the least invasive way to perform colorectal surgery, allowing patients a quick recovery, and decreasing many of the complications associated with more invasive conventional surgery.
Dr. Geisler has utilized single-port surgery in both the pediatric and adult patient population and is currently offering a minimally invasive approach to over 90 percent of the patients he schedules for resective procedures.
Prior to practicing at the Cleveland Clinic, Dr. Geisler was director of minimally invasive colorectal surgery at St. Vincent Health System in Erie, where he also completed his residency in colon and rectal surgery. An additional year of training was later completed in Philadelphia under John Marks, MD, and Gerald Marks, MD, concentrating on minimally invasive surgery as well as the multimodality treatment of low rectal cancers with emphasis on sphincter-preservation surgery.
“We are pleased to have a surgeon of Dr. Geisler’s caliber join West Penn Allegheny Health System to help lead our advanced colon and rectal surgery program,” said Donald Moorman, MD, System Chair, WPAHS Department of Surgery. “His commitment to innovation and personalized care will serve our patients well and allow us to build on our history of excellence in colon and rectal surgery.”
Dr. Geisler received his bachelor’s degree from Austin College in Sherman, Tex., and his medical degree from St. Louis University School of Medicine. He served his internship and residency in general surgery at the University of Oklahoma-Tulsa, where he was named chief resident, and also completed a fellowship in minimally invasive colorectal surgery at The Lankenau Hospital and Institute for Medical Research in Wynnewood, Pa.
A diplomat of the American Board of Surgery, the American Board of Colorectal Surgery and the National Board of Medical Examiners, Dr. Geisler has also authored numerous papers and book chapters and lectured on a wide variety of topics related to minimally invasive surgery and the treatment of colorectal cancer, inflammatory bowel disease and diverticulitis.
Led by Dr. Moorman and C. Neal Ellis, MD, System Director, Colon and Rectal Surgery, the Division of Colorectal Surgery at West Penn Allegheny Health System provides comprehensive diagnostic testing and the latest in minimally invasive surgical techniques to manage benign and malignant diseases of the colon and rectum. The treatment team is focused on its goal of providing patients with optimal care that restores their colorectal health and allows a quick return to normal activities.
