Randomized Trial Comparing Laparoscopic Roux-en-y Gastric Bypass to Micro-laparoscopic Roux-en-y Gastric Bypass - Full Text View

Purpose

Background Laparoscopy is the preferred surgical approach for a number of different diseases as it allows for diagnosis and treatment in the setting of a safe and feasible method offering enhanced cosmesis. The natural evolution of laparoscopy is micro-laparoscopy which utilizes smaller instruments and optics. Technological advancements have enabled miniaturization of the surgical equipment without compromising diagnostic or operative capabilities.

Dr. Keith Zuccala is currently performing micro-laparoscopic gastric bypass with an identical safety profile as traditional laparoscopy (NSQIP data comparison between Dr. Laura Choi and Dr. Keith Zuccala). The current trend in laparoscopy is to minimize incisions and their size to decrease trauma to the abdominal wall.

Study Design Both methods have never been compared in a prospective randomized trial to address the following questions.

Is there a difference in outcome?
Is there a decrease in postoperative pain?
Does it decrease time off from work?
Does micro-laparoscopy increase OR time?
What is the effect on cost of micro-laparoscopy? Patients will be randomized to one or the other method, disclosing that to the investigators best knowledge both methods are equally safe and that Dr. Zuccala has performed several hundred cases using both methods.

Patient Population Projected sample size would be 50 patients in each group. Accrual should be feasible over the course of 9-12 months.

Data collection (patients will be followed for a total of 30 days for the purpose of this study)

NSQIP data to assess outcome
Postoperative usage of pain medication while in the hospital
Time off from work
OR time
Direct cost of procedure as it relates to material used

Arms	Assigned Interventions

Active Comparator: Laparoscopic gastric bypass	Procedure: Laparoscopic Surgery laparoscopic gastric bypass will be performed using standard of care procedure.

Detailed Description:

This study compares two groups of patients who have voluntarily chosen to undergo roux-n-y gastric bypass surgery. The groups will be randomized to receive micro-laparoscopic or laparoscopic surgery to be performed by the same surgeon, Dr. Keith Zuccala.

Study Schema

The patient attends an informational seminar conducted by the Bariatric Surgery Department
The patient is scheduled for an initial consultation with the bariatric PA/NP where the patient provides: a letter of referral for Bariatric Surgery from primary care doctor or specialty physician; insurance referral; and assurance that health insurance coverage includes Bariatric Surgery.
Following the initial consultation, the patient is scheduled for the following: comprehensive blood testing; psychological screening/evaluation; dietary evaluation; appointment with the surgeon; pulmonary evaluation (if needed); cardiology evaluation (if needed); gastroenterology evaluation (if needed).
An appointment for medical clearance with the referring surgeon is scheduled and completed within three weeks of surgery. At this appointment an electrocardiogram (EKG) and repeat blood work will be carried out.
The patient is deemed to meet all inclusion criteria.
The patient is advised to follow all pre-operative instructions as advised by the nursing staff and explained in the Danbury Hospital Center for Weight Loss Surgery Guide.
Surgical procedures performed are standard for those already utilized daily in the surgery department for gastric bypass procedures.
The patient is closely observed in the hospital and given specific discharge instructions upon leaving the hospital
The patient is followed for a maximum of 60 days after surgery and asked how many days of work they missed.
The NSQIP data base and patient medical record are used to assess outcome, postoperative pain, OR time and surgery cost
