Innovations & Outcomes

At Massachusetts General Hospital, minimally invasive surgery is a standard of care and our preferred surgical approach to treat a wide range of conditions.

Performing a high volume of surgical procedures each year, surgeons in Mass General’s Division of Gastrointestinal & Oncologic Surgery are leading providers of minimally invasive surgical techniques—also called laparoscopic surgery—to treat metabolic, gastrointestinal, pancreatic and other conditions.

Using high-definition imaging technology and precision instruments, our surgeons work through a few tiny incisions to perform thousands of these procedures each year. This high-volume experience means better outcomes for patients and helps our surgeons lead new innovations in the field and integrate these techniques into patient care.

Compared with traditional, or open, surgery, minimally invasive surgery generally involves:

• A quicker recovery and return to normal activities
• An earlier discharge, as many procedures are done on an outpatient basis
• Dramatically reduced bleeding and postoperative pain
• Fewer and/or smaller scars

Leaders in Minimally Invasive Surgery

Our surgeons are board-certified and Harvard Medical School-affiliated. They are highly experienced in performing minimally invasive procedures for complex cases ranging from those that do not require external incisions, to treating cancers of the stomach and the esophagus in a completely minimally invasive manner.

Our doctors are leaders in their field nationally, with many serving as presidents of several national societies such as the Society of American Gastrointestinal and Endoscopic Surgeons, the Society for Surgery of the Alimentary Tract, the American Pancreatic Association and the Society of University Surgeons.

Our Procedures

As part of our approach to your care, our surgeons will recommend, whenever possible, the least invasive and most effective method to treat your condition, factoring in your health history, lifestyle and goals for treatment. Our division performs a number of minimally invasive procedures, including:

Laparoscopy for Staging Pancreatic and Gastric Cancers

This is performed so that unnecessary surgery is prevented.

Laparoscopic Distal Pancreatectomy

The left side of the pancreas is removed to treat cystic and endocrine tumors.

Laparoscopic Liver Resection

Liver mass (benign or cancerous) is safely and efficiently removed.

Laparoscopic Heller Myotomy

The muscle at the lower end of the esophagus is cut precisely to relieve difficulty swallowing (achalasia).

Laparoscopic Fundoplication

Used to rebuild the valve between the stomach and esophagus to stop gastroesophageal reflux (GERD).

Endoscopic Antireflux Procedures (esophyx and medigus)

Performed to rebuild the valve between the stomach and esophagus to stop GERD.

Laparoscopic Hiatal and Paraesophageal Hernia Repair

Used to repair hiatal hernias and paraesophageal hernias.

Laparoscopic Gastrectomy

A portion of the stomach is removed to treat gastrointestinal stromal (GIST) tumors and small cancers of the stomach.

Laparoscopic Surgery for Obesity

Including Roux-en-Y gastric bypass, lap band and laparoscopic sleeve gastrectomy.

Laparoscopic Adrenalectomy

Removal of the adrenal gland to treat tumors of the adrenal gland.

Laparoscopic Splenectomy

Performed to remove the spleen to treat idiopathic thrombocytopenic purpura (ITP), a blood disorder, splenic masses or cysts.

Laparoscopic Colectomy and Colon Resection

The laparoscopic removal of part or all of the large intestine for benign conditions such as diverticulitis and large polyps, as well as colorectal cancers.

Transanal Endoscopic Microsurgery

Local excision of rectal tumors/cancer.

Minimally Invasive Surgery Fellowship

The division offers a Minimally Invasive Surgery Fellowship designed to help fellows develop technical proficiency in advanced laparoscopic surgery and advanced gastrointestinal procedures.
