Laparoscopic/Open - Colorectal surgeries

Laparoscopic/Open - Colorectal surgeries

Colorectal surgeries encompass a range of surgical procedures performed to treat conditions affecting the colon, rectum, and anus. These surgeries may be performed to treat colorectal cancer, inflammatory bowel diseases, diverticulitis, colorectal polyps, and other conditions.


A hemicolon resection, or hemicolorectomy, is a surgical procedure involving the removal of one-half (hemicolectomy) of the colon. During a hemicolorectomy, the affected segment of the colon is removed along with nearby lymph nodes to reduce the risk of cancer metastasizes.

Low Anterior Resection (LAR)

Rectal cancer is treated with LAR surgery. The portion of the rectum that has cancer will be removed during LAR surgery. The colon will be reconnected to the remaining portion of the rectum. After recovery, the patient can poop as usual.

Abdominoperineal resection (APR)

Abdominoperineal resection (APR) is a surgical procedure performed to treat rectal cancer, mainly when the tumour is located very low in the rectum or involves the anal canal. This method consists of the removal of the rectum, anus, and surrounding tissues, followed by the creation of a permanent colostomy to allow for the passage of stool.

Laparoscopic/Open - Gastric surgeries

Gastric surgeries encompass a variety of surgical procedures involving the stomach. These procedures are performed to treat various conditions affecting the stomach, including obesity, gastric cancer, ulcers, and gastrointestinal disorders.

Total gastrectomy

Total gastrectomy is a surgical procedure in which the entire stomach is removed. It is typically performed to treat advanced stomach cancer, certain types of gastric tumours, or severe cases of benign conditions such as peptic ulcers or gastric polyps that cannot be managed through other treatments.

Sub-total gastrectomy

Subtotal gastrectomy, also called partial gastrectomy, is a surgical procedure where a portion of the stomach is removed while the remaining part is preserved. It is used to treat conditions such as gastric cancer, ulcers, or tumours confined to a specific area of the stomach.

Distal gastrectomy

A distal gastrectomy is a surgical procedure involving the removal of the lower portion (distal part) of the stomach. This method is performed to treat conditions affecting the lower part of the stomach, such as gastric cancer or peptic ulcers, that cannot be managed through other treatments, such as medications or endoscopic procedures.


Esophagectomy is a common surgery to treat esophageal cancer. In this procedure, the surgeon removes all or part of the esophagus and also nearby lymph nodes through incisions in the chest, abdomen or both. They then reconstruct the esophagus using the stomach or colon. There are three types of esophagectomies:

Transthoracic esophagectomy (TTE)

Transhiatal esophagectomy (THE)
