Upper gastrointestinal surgery:

Upper gastrointestinal surgery, often referred to as upper GI surgery, refers to a practise of surgery that focuses on the upper parts of the gastrointestinal tract. There are many operations relevant to the upper gastrointestinal tract.

Upper G.I. surgery includes the following operations:

Dr. Hassan performs the following Gastric Surgerjes: for ulcer or tumor benign and malignant, small bowel surgery for obstruction and tumors, laproscopic gall baldder surgery and exploration of the common bile duct.

Lower gastrointestinal surgery:

Lower gastrointestinal surgery refers to a sub-specialisation of medical practice whereby a general surgeon focuses on the lower gastrointestinal tract.

Laproscopic Appendectomy

The majority of cases of acute appendicitis are performed using the laproscopic technique using small incsions. Most of the patients can be discarged within 24 hours, can ambulate easily and return to work quicker.

Colectomy

A colectomy is surgery to remove the colon (large intestine) to treat various medical conditions. It is the primary treatment for colorectal cancer and is often curative. A colectomy, or colon resection, may involve removing all or part of the colon, depending on the specific condition treated.

In a partial colectomy, the surgeon removes the part of the colon that contains the cancer, along with a portion (margin) of surrounding normal tissue. A “clean margin” helps assure there are no malignant cells left in the area. The remaining portion of the colon is then sewn back together. In a total colectomy, the entire colon is removed. In such cases, a colostomy is also necessary to provide the patient with an alternate way to eliminate wastes from the body.

Increasingly, laparoscopic surgery is being used to perform colectomy and other colorectal cancer treatments. It uses several small incisions in the abdomen and a long, narrow tube called a laparoscope. The laparoscope is inserted into the body cavity and surgical instruments are used to remove cancerous sections of the colon. Compared to traditional colectomy surgery, laparoscopic surgery involves smaller incisions, is less likely to cause significant scarring and may result in faster recovery with less pain.

Dr. Hassan uses laproscopic assisted surgical technique in the managment of colonic tumors , diverticulitis and appendicitis.

Low resections for rectal cancer

Over the past twenty five years, there have been significant improvements in surgical techniques for the treatment of rectal cancer. In the past, a majority of patients required a colostomy after rectal cancer surgery and developed significant side effects (such as incontinence and male impotence) from nerve damage that frequently occurred during the surgery. The utilization of pre-operative chemoradiation (combination of chemotherapy and radiation) and improved surgical techniques has led to fewer side effects and fewer patients requiring colostomy.

Surgery is the most common treatment for rectal cancers. If the tumor is relatively small, it can be removed by a surgical procedure called local excision, which removes only the cancerous area.

A larger tumor requires a resection (removal of the tumor and some healthy tissue surrounding it) and anastomosis (the two tumor-free ends of the bowel are reconnected). If the bowel ends cannot be reconnected, a colostomy is made. Preoperative chemotherapy & radiation (called neoadjuvant therapy) can improve how successful the surgeon is at completely removing the tumor.

Dr. Hassan uses combined transanal and abdominal resections of this very low canceous tumor of the rectum. He uses staples techniques to resect the tumors and minimize the need to perform colostomy.
