List of Treatments:


  • Anti-Reflux Procedures: This type of procedure is used for the treatment of conditions in which food or stomach acid flows back up into the esophagus from the stomach. This entails stitching the hole in your diaphragm shut to prevent your stomach from bulging upward through the muscle wall opening. To strengthen the healed region, some surgeons insert a piece of mesh. Stitch the upper section of your stomach around the end of your esophagus.


  • Lap Cholecystectomy - Gallbladder Removal: It is a type of procedure in which the gallbladder is usually removed during a cholecystectomy by introducing a tiny video camera and specific surgical equipment through four small incisions in your belly. This is known as a laparoscopic cholecystectomy. In certain circumstances, the gallbladder may be removed by a single big incision.


  • Hepatitis B Treatment: Hepatitis B is caused by hepatitis B virus. Hepatitis B is transmitted when blood, sperm, or other bodily fluids from an infected person enter the body of an uninfected person. Antiviral medicines may be used to treat chronic hepatitis B. However, Orthotopic liver transplantation, on the other hand, is the therapy of choice for patients with fulminant hepatic failure who do not recover and for individuals with end-stage liver disease related to hepatitis B.


  • Hepatitis C Treatment: Hepatitis C is a liver inflammation caused by the hepatitis C virus. Direct-acting antiviral (DAA) pills are used to treat Hepatitis C. DAA pills are the most effective and safest drugs for treating hepatitis C. However, chronic hepatitis C is treated by liver transplantation. During a liver transplant, your diseased liver is removed and replaced with a healthy liver.


  • Liver Cirrhosis Treatment: Cirrhosis is a disorder that causes your liver to scar and become permanently damaged. Scar tissue replaces good liver tissue, preventing the liver from functioning correctly. Cirrhosis causes your liver to fail as it progresses. Treatment include medications such as diuretics and liver transplant in chronic conditions.


  • Biliary Drainage and Stenting Surgery: Biliary drainage is a treatment that aids in the removal of excess bile. When bile becomes clogged in the bile duct, it can back up into the liver, causing symptoms such as jaundice. A biliary drain is a thin, hollow tube having many perforations along its length which facilitates bile flow.


  • Whipple Surgery: It is a complicated procedure that involves removing the pancreatic head, the first section of the small intestine (duodenum), the gallbladder, and the bile duct. The Whipple surgery is used to treat tumors and other pancreatic, intestinal, and bile duct diseases.


  • Appendectomy: If you have appendicitis, your appendix will be removed. When the appendix becomes infected, surgery is performed to remove it. Appendicitis is the medical term for this ailment. An appendectomy is a frequent emergency procedure. The appendix is a small pouch connected to the big intestine. It is located in the bottom right quadrant of your abdomen.


  • Hemorrhoidectomy: A hemorrhoidectomy is surgery to remove internal or external haemorrhoids. These are anal veins that have swelled. During this procedure, the doctor will remove the enlarged veins. Surgery is rarely used as the first line of therapy. When everything else fails, hemorrhoidectomy is a safe, effective procedure that does more than merely make haemorrhoids less bothersome.


  • Partial colectomy: Part of the colon is removed during a partial colectomy, which is also known as a subtotal colectomy. Hemicolectomy is the surgical removal of either the right or left side of the colon. The colon and rectum are both removed during a proctocolectomy.


  • Nissen fundoplication: A Nissen fundoplication is a surgical procedure that is used to treat gastroesophageal reflux disease (GERD). To avoid acid reflux, a surgeon constructs a sphincter (tightening muscle) at the bottom of the oesophagus during the surgery.To avoid acid reflux, the operation tightens the connection between the oesophagus and the stomach.


  • Endoscopy: An endoscopy is a procedure that allows you to see within the structure of your body. An endoscope is a long, thin tube with a tiny camera inside that is introduced into your body through a natural orifice such as your mouth. If you have specific symptoms, your doctor may recommend you for an endoscopy. It is normally performed in a hospital endoscopy unit.
