Dr. Weiss strives to maximize patient safety and satisfaction by performing the most appropriate surgical procedures using the least invasive techniques possible. Fellowship trained in minimally invasive surgery and flexible endoscopy, Dr. Weiss performs most general surgical procedures, including:

  • laparoscopic cholecystectomy (removal of the gallbladder)
  • ventral (abdominal wall) hernias and inguinal (groin) hernia repair
  • colon resection
  • appendectomy
  • lysis of adhesions (removal of abdominal scar tissue)
  • gastric surgery
  • abscess drainage
  • cyst or mole removal
  • laparoscopic splenectomy
  • upper endoscopy
  • small bowel resection
  • LAP-BAND removal


About 1 out of every 13 adults in America suffers from severe obesity. Forecasts suggest that by the year 2030, nearly 11% of the population will be considered severely obese. Carrying extra weight takes an extreme toll on the body causing heart disease, stroke, type 2 diabetes and certain types of cancer — some of the leading causes of death. For many, weight loss through diet and exercise alone is not sufficient. Patients must consider surgical weight loss options, which include bariatric surgery.

Dr. Weiss offers the full range of bariatric surgery care services, including inpatient care, post-operative care, outpatient follow-up care, and patient education.

The most commonly performed bariatric surgeries are a gastric sleeve and gastric bypass. Each procedure has its advantages and disadvantages. Candidates are encouraged to ask questions to help with this decision. Dr. Weiss’s approach is that the patient is the best person to determine which procedure is right for them. Ultimately it is the responsibility of the patient to adopt the behavioral changes necessary to ensure long-term success.

The gastric sleeve is now the #1 bariatric surgery for weight loss. The gastric sleeve decreases stomach capacity by surgically removing the greater curvature of the stomach. The stomach is therefore much smaller and able to hold less food. A gastric sleeve also decreases appetite as the hunger hormone (ghrelin), which is stored in the curvature, is decreased by the removal of this portion of the stomach. Benefits of gastric sleeve include: no re-routing of the intestines; no significant nutritional deficiencies; no implantation of a foreign object; and weight loss can continue for more than a year.

This is an irreversible procedure and usually requires an inpatient hospital stay of 2 days.


Gastric bypass is a procedure that uses both restriction and malabsorption to help patients achieve weight loss. First, the stomach is stapled to create a smaller pouch. Then, most of the stomach and part of the intestines are bypassed by attaching a part of the intestine to the small stomach pouch. Gastric bypass is non-adjustable and is not intended to be reversed. It has its primary effect over the course of the first year.


Hernias are quite common, affecting more than 3 million Americans each year.  They happen when the inner layers of the abdominal muscle become weakened and the lining of the abdomen then bulges out into a small sac. Part of the intestines or abdominal tissue may then enter the sac. The most common symptom is bulging in the affected area and can include pain or discomfort along with weakness, pressure or a feeling of heaviness. Some also experience nausea, difficulty with bowel movements, and even vomiting.

Hernias commonly occur near the belly button (umbilical), in the abdomen (ventral), and in the groin (inguinal).

We are all born with areas of natural weakness in the abdominal wall.  Some people are predisposed to hernias because of a congenital defect that causes their abdominal wall to be abnormally thin. Other risk factors include:

  • Age
  • Obesity
  • Pregnancy
  • Smoking
  • History of Abdominal Surgeries
  • Injuries to the Bowel Area
  • Family History of Hernias
  • Frequent Lifting or Pushing of Heavy Objects
  • Coughing
  • Frequent Constipation with Straining and Pushing

Not all hernias require surgical repair, but approximately half a million hernias are severe enough to require surgical correction each year in the United States. If you experience constant, intense pain, nausea or vomiting, it may be that a piece of intestine is trapped in the hernia, referred to as an incarcerated hernia. This requires immediate surgery. The large majority of hernias can be repaired electively.

Dr. Weiss repairs both ventral (abdominal wall) and inguinal (groin) hernias.

Ventral Hernias: Ventral hernias can occur anywhere along the abdominal wall and are sometimes referred to as incisional hernias because they happen in as many as 30% of people who’ve had abdominal surgery. They commonly occur at the site of the surgical scar where scar tissue thins or weakens allowing a bulge to form in the abdomen.

Inguinal Hernias:  Most common in men over 40, about 1 in 4 males will have an inguinal hernia at some point during their lives.   It’s named for the inguinal canal, a passage in the lower abdomen that houses blood vessels and nerves as well as the spermatic cord in males. Inguinal hernias are far less common in women due to anatomical differences.

Symptoms include pain or bulging when coughing, bending, or lifting heavy objects. Men may also experience swelling around the testicles, or feel pressure or weakness in the groin.

Most hernias can be repaired with a minimally invasive (laparoscopic) procedure.  Using multiple small openings and a camera, Dr. Weiss will push tissue back into place and then secure it with stitches and/or a mesh patch for reinforcement to prevent recurrence.

Laparoscopic hernia surgery is often outpatient, depending on the size of the hernia. You will go home the same day as surgery and can expect several days of discomfort. You will be allowed to walk immediately after your procedure and are permitted to resume normal activities as pain allows. Following surgery, hernia patients should limit the weight and amount of lifting they do for 2-6 weeks following surgery.
