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.

Bariatric surgery is a surgical procedure used to manage obesity and obesity-related conditions. Long term weight loss with bariatric surgery may be achieved through alteration of gut hormones, physical reduction of stomach size, reduction of nutrient absorption, or a combination of these. Standard of care procedures include Roux en-Y bypass, sleeve gastrectomy, and biliopancreatic diversion with duodenal switch, from which weight loss is largely achieved by altering gut hormone levels responsible for hunger and satiety, leading to a new hormonal weight set point.
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.
Single-incision laparoscopic surgery (SILS) is an advanced, minimally invasive (keyhole) procedure in which the surgeon operates almost exclusively through a single entry point, typically the patient's umbilicus (navel). Special articulating instruments and access ports eliminate the need to place trochars externally for triangulation, thus allowing the creation of a small, solitary portal of entry into the abdomen.

He is the President of IRCAD India, the only center of excellence in India dedicated entirely to training and Research & Development in the field of minimally invasive surgery.
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.
