Areas of Specialization on Various kinds of Bariatric Surgery

Our team approach means that every patient receives the highest level of care, before, during, and after surgery. We provide each patient with personal attention and expert guidance to make their Bariatric surgery—and their journey toward a new, healthier life—a success.

Bariatric Surgery

Bariatric Surgery or Weight Loss Surgery is an operation that helps you lose weight by making changes to your digestive system. Some types of bariatric surgeries make your stomach smaller, allowing you to eat and drink less at one time and making you feel full sooner.

Laparoscopic Surgery

Laparoscopy translated from Ancient Greek- lapara meaning ‘flank or side’, and skopeo meaning ‘to see’ is an operation performed in the abdomen or pelvis using small incisions (usually 0.5–1.5 cm) with the aid of a camera.

Laser Surgery

The term “laser” stands for Light Amplification by Stimulated Emission of Radiation. Ordinary light, such as that from a light bulb, has many wavelengths and spreads in all directions. Laser light, on the other hand, has a specific wavelength.


Endoscopy (also known as Upper GI Endoscopy, Gastroscopy, EGD or esophagogastroduodenoscopy) is a procedure that enables Dr. Christopher to examine the lining of the esophagus (swallowing tube), stomach and duodenum (first portion of the small intestine).


Many people in Tirunelveli go for a colonoscopy procedure. Colonoscopy is a procedure that allows a specialist to observe the lining of the colon and rectum. It is done in most hospitals and performed as an endoscopic procedure or on an outpatient basis by a gastroenterologist in Tirunelveli.

Robotic Surgery

Robotic surgery, or robot-assisted surgery, allows doctors to perform many types of complex procedures with more precision, flexibility and control than is possible with conventional techniques. Robotic surgery is usually associated with minimally invasive surgery — procedures performed through tiny incisions.
We have to be cautious about Obesity to build extra awareness.
