Ongoing research in colorectal disease
Dr. Eric Haas, Houston colon surgeon, is committed to furthering research in colorectal disease. There are currently six studies that Dr. Eric Haas is involved in.
Several studies have shown that new surgical techniques have the potential of improving outcomes following colorectal surgery. Robotic-assisted laparoscopic surgery has emerged as a viable option for colorectal procedures, offering various visual and operative advantages. The purpose of the this study is to compare short-term and pathology outcomes in patients that undergo colorectal surgery, either with robotic-assisted laparoscopic surgery or conventional laparoscopic surgery. ?This study involves gathering anonymous data from patient records in order to compare and evaluate the efficacy of this new surgical approach with an established surgical technique.
Single-site or single-incision laparoscopic surgery offers many potential advantages for the surgical treatment of colorectal diseases. This minimally invasive laparoscopic technique is performed entirely through the umbilicus and results in minimal scar with diminished pain. This trial will compare the clinical outcomes of single-site laparoscopic surgery with those obtained through conventional laparoscopic surgery of the colon and rectum.
Minimally invasive surgery has emerged as a viable option for the treatment of benign and malignant colorectal disease. ?Comparisons of intra-operative results and post-operative outcomes have been well documented in the literature. While comparisons between laparoscopic and open surgery are well reported, there are few, if any, reports of comparisons between the different types of minimally invasive surgery (e.g., conventional, hand-assisted, single-incision, or robotic-assisted laparoscopic surgery). Short- and long-term outcomes with regard to quality of life are seldom reported following any surgical procedure. ?The purpose of this study is to assess QOL outcomes, through completed questionnaires, in patients undergoing minimally invasive surgery for colorectal disease.

Fecal incontinence (FI) affects between 2% and 17% of the population and seriously affects their quality of life (QOL). ?FI is observed most often in females, the elderly, and individuals of poor health. ?Conservative treatments (e.g., avoidance of spicy foods, increased fiber intake, and bowel retraining programs) are successful for some patients but result in no improvement for others. ?For these frustrated patients, radiofrequency energy delivery to the anal canal musculature using the SECCA device may provide a viable option combined with the advantage of a minimally invasive approach. Numerous studies have reported on the safety of SECCA and outcomes have been assessed with conventional QOL indicators such as the CCFIS and FIQL scores. However, the effect of SECCA has not yet been objectively evaluated using anatomic and functional measurements of sphincter muscles. The purpose of this study is to quantitatively evaluate physiological outcomes (through use of 3D ultrasound and anal manometry) after SECCA and correlate these with traditionally assessed QOL outcomes.
Pelvic muscle rehabilitation (PMR) is a modern and non-invasive treatment modality involving cognitive retraining of the pelvic floor and abdominal wall muscles. Patients are counseled to optimize strength, endurance and reproducibility of pelvic muscle contractions under the guidance of a trained therapist with continuous functional analysis not visible to the patient. Each session consists of: 1) muscle strength and endurance, 2) isolation and control of accessory muscles and 3) electrical muscle stimulation. Each PMR session lasts for approximately 30 minutes and is repeated at 1-2 week intervals. Dietary and behavioral education is discussed at each session and the patient is prescribed a home exercise program. Presently, there are no published reports in regards to the efficacy of PMR for the treatment of FI. The purpose of this study is to assess outcomes of PMR on pelvic floor disorders, specificall fecal incontinence (FI), through quantitative (muscle strength, endurance, fatigue, percent improvement) and qualitative (QOL questionnaires) measures.
Pelvic muscle rehabilitation (PMR) is a non-invasive, modern modification of traditional biofeedback involving cognitive retraining of the pelvic floor and abdominal wall muscles. Patients are counseled to optimize strength, endurance and reproducibility of pelvic muscle contractions under the guidance of a trained therapist with continuous anal manometry and electromyography not visible to the patient. Each session consists of: 1) muscle strength and endurance, 2) isolation and control of accessory muscles and 3) electrical muscle stimulation. Each PMR session lasts for approximately 30 minutes and is repeated at 1-2 week intervals. Dietary and behavioral education is discussed at each session and the patient is prescribed a home exercise program. Presently, there are no published reports in regards to the efficacy of PMR for the treatment of ODS. The purpose of this study is to access outcomes of PMR on pelvis floor disorders, specifically obstructed defecation (ODS)/constipation, through quantitative (muscle strength, endurance, fatigue, percent improvement) and qualitative (QOL questionnaires) measures.
Holding positions as director, chief, or faculty of three teaching hospitals and two medical schools, Dr. Eric Haas, Houston colorectal surgeon, promotes and conductions many research projects with the aim of improving quality of life for people suffering from colorectal dysfunction, and reducing the loss of function associated with colon cancer and colorectal surgery in Houston.
