Obesity (bariatric) surgery refers to a group of surgical procedures used to treat excess weight when diet and lifestyle changes alone have not been sufficient. Techniques include reducing stomach volume or rearranging part of the digestive tract. The specific procedure is chosen based on the patient's body mass index, associated health conditions, and overall health status. The period after surgery includes ongoing nutritional and lifestyle follow-up.

Gastric cancer surgery treats cancer detected in the stomach by removing part or all of the stomach, depending on how far the disease has spread. Nearby lymph nodes are also examined during the operation and removed if necessary. Chemotherapy may be given before or after surgery depending on the stage of disease. The treatment plan is determined through a multidisciplinary approach based on imaging and endoscopic findings.

Colorectal cancer surgery involves the surgical removal of cancerous tissue in the colon or rectum. Depending on the location of the disease, the operation can be performed using open or laparoscopic techniques. Nearby lymph nodes are evaluated as part of the procedure when appropriate. Chemotherapy or radiotherapy may be added before or after surgery depending on the stage of the disease.

Liver tumor treatment covers the evaluation and management of benign or malignant masses found in the liver. Treatment options can include surgical removal of the tumor, image-guided interventional techniques, or a combination of these approaches. The choice of method takes into account the tumor's size and location as well as the liver's overall function. The treatment plan is decided following a multidisciplinary evaluation.

Pancreatic cancer surgery is a technically complex procedure aimed at removing cancerous tissue from the pancreas. The extent of the operation depends on the tumor's location within the pancreas and its relationship to nearby blood vessels and organs. Chemotherapy may be given before or after surgery depending on the stage of the disease. Treatment is planned jointly by the surgical and oncology teams.

Laparoscopic splenectomy is a minimally invasive procedure that removes the spleen through small incisions using a camera and specialized surgical instruments. It may be considered for certain blood disorders, spleen enlargement, or other spleen-related conditions. When suitable, the technique allows for smaller incisions compared with open surgery. The procedure is generally performed under general anaesthesia.

Gastric sleeve surgery is a bariatric procedure in which a large portion of the stomach is removed, leaving a narrow, tube-shaped stomach. The goal is to reduce stomach volume and limit the amount of food that can be consumed at one time. It is typically performed laparoscopically through small incisions. Nutritional and general health assessment before and after the operation is part of the overall treatment process.
