Michigan Institute of Bariatric Surgery

Dr. Marshall is one of the senior surgeons of the Division of Bariatric Surgery at St. John Macomb Oakland Hospital where we have a Comphrensive Bariatric Surgical Weight-Loss Program. Our operating room is well-equipped to handle even the largest of patients. Our Anesthesiologists are very experienced in the care of bariatric patients. We also have a well equiped  state of the art ICU.

St. John Macomb Oakland Hospital has a full array of services to provide the care needed for our bariatric patients. There is a bariatric clinic right next door to the hospital where all of the patients are seen both preoperativly and postoperativly. Specialty areas are covered with available Internal Medicine, Cardiology, Pulmonary, Infectious Disease, Intensive Care, Rehabilitation Medicine, Dietary, Pharmacy, Radiology and Emergency Medicine etc.

Morbid Obesity is a very common problem in the USA as well as the rest of the developed world. Patients interested in Bariatric Surgery need to be well-informed to make sure that this is the right choice for them. We have monthly Education Seminars as well as Pre-Surgical Education Classes and Support Group Sessions. We provide much of the information to our patient during our office surgical consultation. We work along side the primary care physicians who assist us with thorough pre-operative evaluations. Dr. Marshall will take time to consult with you, determine your individual needs and goals, and create a plan which will ensure a high level of quality in your care.

Dr. Marshall sees all of his patients in the bariatric clinic for follow-up care where they get the personal attention of the Surgeon as well as bariatric nurses, dieticians and nurse practitioners. We plan on life-long follow-up with at least yearly visits to check necessary laboratory testing and to make sure our patients stay on track with necessary vitamins, minerals and life-style changes. It is crucial that patients see a Bariatric Surgeon knowledgeable in the follow-up care of bariatric patients to make sure they have continued successes.

Dr. Marshall performs Laparoscopic Roux-En-YGastric Bypass, Sleeve Gastrectomy and Gastric Banding procedures (both Lap-Band and Realize Band). The Gastric Bypass  includes both short and long limb procedures needed for larger patients with a Body Mass Index (BMI) over 50. Dr. Marshall also is experienced in performing Bariatric Revisional Procedures which is usually a repair or conversion of a failed previous bariatric surgery. This includes Endoscopic revision such as Sclerotherapy. 

After the weight loss, many patients are interested in having the extra skin and fat removed from the abdomen, upper arms, legs and other areas. Dr. Marshall has had considerable experience in performing Abdominoplasty (removal of excess skin from the lower abdomen), Brachioplasty (removal of excess skin from the upper under arms) and Thigh Plasty (removal of excess skin from the upper, inner thighs). We are associated with other plastic surgeons who perform all of the other plastic procedures patients may seek after extreme weight lost such as breast-lift (mastopexy), augmentation (breast implants), breast reduction, facial plastics, liposuction and other procedures. Dr. Marshall performs his own endoscopic procedures such as esophago-gastroendoscopy (EGD, EGJ), and colonoscopy. He is one of the only surgeons in the area to perform Endoscopic Sclerotherapy for dilated stomas (enlargement of the stomach-pouch opening), which can be a cause of weight regain and insufficient weight-loss after some types of gastric bypass procedures. Dr. Marshall also treats some gastric fistulas with an endoscopic sealant which is helpful in some cases. Dr. Marshall also performs many other bariatric-related procedures. Bariatric Procedures Performed by Dr. Marshall:

• Open Gastric Bypass (rarely needed)
• Laparoscopic Gastric Bypass
• Roux-en-Y Gastric Bypass Surgery
• Gastric Revision-Conversion surgery Other Bariatric Related Procedures
• Cholecystectomy, open and laparoscopic
• Ventral Hernia Repair, open and laparoscopic, inguinal hernia repair
• Liver Biopsy
• Repair of Small bowel Obstruction
• Other General Surgical Procedures

Gastric Bypass is the gold standard for bariatric surgery and combines both a restrictive component with a malabsorptive component which results in optimum weight loss with few complications. Expected weight loss with a gastric by-pass is 75 percent of the excessive weight will be lost. Our patients commonly lose 75-85 percent of their excess weight in the first year and many patients continue to improve this up to 2 years. There can be a regain of 10-15 % after two years. Long term results of gastric by-pass have been consistent for the past 20 years. Any weight regain is usually minimal (10-15 pounds) - any more than this may suggest that some problem exists such as stomal dilation (where the pouch opening is too large), pouch dilation (when the pouch stretches too large) or gastric fistulas (when there is an abnormal opening into the old stomach). All of these are treatable.
