General surgery is a surgical specialty that focuses on alimentary canal and abdominal contents including the esophagus, stomach, small intestine, large intestine, liver, pancreas, gallbladder, appendix and bile ducts, and often the thyroid gland. General surgeons also deal with diseases involving the skin, breast, soft tissue, trauma, peripheral artery disease and hernias and perform endoscopic as such as gastroscopy, colonoscopy and laparoscopic procedures.
Laparoscopy is an operation performed in the abdomen or pelvis using small incisions with the aid of a camera. The laparoscope aids diagnosis or therapeutic interventions with a few small cuts in the abdomen.
Cholecystectomy is the surgical removal of the gallbladder. Cholecystectomy is a common treatment of symptomatic gallstones and other gallbladder conditions. In 2011, cholecystectomy was the eighth most common operating room procedure performed in hospitals in the United States. Cholecystectomy can be performed either laparoscopically, or via an open surgical technique.
Gastric bypass surgery refers to a technique in which the stomach is divided into a small upper pouch and a much larger lower "remnant" pouch, where the small intestine is rearranged to connect to both. Surgeons have developed several different ways to reconnect the intestine, thus leading to several different gastric bypass procedures (GBP). Any GBP leads to a marked reduction in the functional volume of the stomach, accompanied by an altered physiological and physical response to food.
Robot-assisted surgery or robotic surgery are any types of surgical procedures that are performed using robotic systems. Robotically assisted surgery was developed to try to overcome the limitations of pre-existing minimally-invasive surgical procedures and to enhance the capabilities of surgeons performing open surgery.
Marc Bessler is an American surgeon known for his innovations in bariatrics. He is currently the United States Surgical Professor of Surgery at Columbia University Medical Center. Starting in July 2024, he will be the Chair of the Department of Surgery at Northwell Health Lenox Hill Hospital. He also serves as a content contributor for Bariatric Surgery Source. Bessler specializes in surgical management of morbid obesity and laparoscopic surgery of the stomach, among other specialties.
Stretta is a minimally invasive endoscopic procedure for the treatment of gastroesophageal reflux disease (GERD) that delivers radiofrequency energy in the form of electromagnetic waves through electrodes at the end of a catheter to the lower esophageal sphincter (LES) and the gastric cardia – the region of the stomach just below the LES. The energy heats the tissue, ultimately causing it to swell and stiffen; the way this works was not understood as of 2015, but it was thought that perhaps the heat causes local inflammation, collagen deposition and muscular thickening of the LES and that it may disrupt the nerves there.
Camran Nezhat, FACOG, FACS is an American laparoscopic surgeon, reproductive endocrinology and infertility sub-specialist who has been teaching and practicing medicine and surgery as an adjunct clinical professor of surgery, and obstetrics and gynecology at Stanford University Medical Center in Palo Alto, California since 1993. Nezhat is also chair of the Association of the Adjunct Clinical Faculty, Stanford University School of Medicine, and a clinical professor of OB/GYN at the University of California, San Francisco.
Pyloromyotomy is a surgical procedure in which a portion of the muscle fibers of the pyloric muscle are cut. This is typically done in cases where the contents from the stomach are inappropriately stopped by the pyloric muscle, causing the stomach contents to build up in the stomach and unable to be appropriately digested. The procedure is typically performed in cases of "hypertrophic pyloric stenosis" in young children. In most cases, the procedure can be performed with either an open approach or a laparoscopic approach and the patients typically have good outcomes with minimal complications.
Single-port laparoscopy (SPL) is a recently developed technique in laparoscopic surgery. It is a minimally invasive surgical procedure in which the surgeon operates almost exclusively through a single entry point, typically the patient's navel. Unlike a traditional multi-port laparoscopic approach, SPL leaves only a single small scar.
Revision weight loss surgery is a surgical procedure that is performed on patients who have already undergone a form of bariatric surgery, and have either had complications from such surgery or have not achieved significant weight loss results from the initial surgery. Procedures are usually performed laparoscopically, though open surgery may be required if prior bariatric surgery has resulted in extensive scarring.
Kurt Karl Stephan Semm was a German gynecologist and pioneer in minimally invasive surgery. He has been called "the father of modern laparoscopy".
Pradeep Kumar Chowbey is an Indian surgeon, known for laparoscopic and bariatric surgeries. He is the incumbent Executive vice chairman of the Max Healthcare, Chairman of the Minimal Access, Metabolic & Bariatric Surgery and Allied Surgical Specialities of the Max Healthcare Institute, New Delhi. He is the founder of the Minimal Access, Metabolic & Bariatric Surgery Centre at the Sir Ganga Ram Hospital, New Delhi and has served as the Honorary Surgeon to the President of India, Dalai Lama and the Indian Armed Forces (AFMS). The Government of India awarded him the fourth highest civilian honour of the Padma Shri in 2002.
Tehemton Erach Udwadia was an Indian surgeon and gastroenterologist, considered by many as the father of laparoscopic surgery in India. He was a general surgeon at two Mumbai hospitals, Breach Candy Hospital and Hinduja Hospital and was the founder president of the Indian Association of Gastrointestinal Endo-Surgeons. The Government of India awarded him the fourth highest civilian honour of the Padma Shri, in 2006 and the third highest civilian honour of the Padma Bhushan in 2017 for his contributions to Indian medicine.
Younan Nowzaradan, also known as Dr. Now, is an Iranian-born American doctor, TV personality, and author. He specializes in vascular surgery and bariatric surgery. He is known for helping morbidly obese people lose weight on My 600-lb Life (2012–present).
The per-oral endoscopic myotomy, or POEM, is a minimally invasive surgical procedure for the treatment of achalasia wherein the inner circular muscle layer of the lower esophageal sphincter is divided through a submucosal tunnel. This enables food and liquids to pass into the stomach, a process that is impaired in achalasia. The tunnel is created, and the myotomy performed, using a flexible endoscope, meaning the entire procedure can be done without external incisions.
Transoral incisionless fundoplication (TIF) is an endoscope treatment designed to relieve symptoms of gastroesophageal reflux disease (GERD). The TIF procedure, similar to Nissen fundoplication, alleviates GERD symptoms by wrapping a portion of the stomach around the esophagus.
Erich Mühe was a German surgeon known for performing the first laparoscopic cholecystectomy in 1985.
In medicine, endoscopic sleeve gastroplasty (ESG) is a minimally-invasive, non-surgical (incisionless), endoscopic weight loss procedure that is part of the field of endoscopic bariatric therapies. To perform ESG, a physician sutures a patient’s stomach into a narrower, smaller tube-like configuration. The result is a more restricted stomach that forces patients to feel fuller sooner, eating fewer calories, which facilitates weight loss.
