Colorectal Surgery

Colorectal surgery treats conditions of the colon, rectum and anus, including colorectal and rectal cancer. Dr. Naser Dib's professional profile describes laparoscopic and robotic-assisted colorectal surgery, including rectal cancer surgery and hemicolectomy, as his main specialisation. Since 2011 he has also been an instructor in minimally invasive colorectal surgery workshops (CV).

Conditions commonly treated with colorectal surgery

Colorectal operations are used for colon and rectal cancer, polyps that cannot be removed endoscopically, complicated diverticular disease and selected cases of inflammatory bowel disease, among other conditions. Not every condition needs surgery; tests and specialist assessment come first.

Rectal cancer surgery

Surgery for rectal cancer aims to remove the tumour together with the surrounding mesorectal tissue and lymph nodes while protecting the pelvic nerves. Depending on the tumour's position, the bowel may be reconnected or a stoma may be required. Treatment is planned with oncologists and radiologists.

General information about procedures listed in Dr. Naser Dib's CV. Suitability is always decided individually.

Laparoscopic rectal resection

What it is: Removal of part or all of the rectum through several small incisions, using a camera and laparoscopic instruments. It is most often performed to treat rectal cancer. The remaining bowel is usually reconnected; in some patients a temporary or permanent stoma is needed.
Common reasons: Rectal cancer, and selected non-cancerous conditions such as large rectal polyps that cannot be removed endoscopically.
Before surgery: Treatment is planned after staging tests, commonly colonoscopy with biopsy, pelvic MRI and CT, and discussion by a multidisciplinary team. Some patients receive radiotherapy or chemotherapy, delivered by oncologists, before surgery.
How it is performed: Under general anaesthesia, the affected part of the rectum is removed together with the surrounding fatty tissue that contains lymph nodes (the mesorectum), following anatomical planes. The bowel is then reconnected or a stoma is formed.
Recovery: A hospital stay of several days is common. Bowel habits often change after rectal surgery and may improve gradually over months. Recovery depends on the operation performed and on each patient's health.
Possible risks: Bleeding, infection, leakage from the bowel join (anastomotic leak), injury to nearby organs, urinary or sexual dysfunction, long-term changes in bowel function, blood clots, risks of anaesthesia, and the possible need to convert to open surgery.
Documented experience: Listed among the key oncological procedures in Dr. Naser Dib's CV.

Hemicolectomy

What it is: Removal of the right or left part of the colon, after which the remaining ends of the bowel are joined. It can be performed as open, laparoscopic or robotic-assisted surgery.
Common reasons: Most commonly colon cancer. Other reasons can include polyps that cannot be removed during colonoscopy and selected cases of diverticular or inflammatory bowel disease.
Before surgery: Colonoscopy, imaging and blood tests are typically completed beforehand. The surgical team explains any bowel preparation, medication changes and fasting instructions.
How it is performed: The diseased segment of colon is removed with its blood supply and nearby lymph nodes, and the bowel is reconnected (anastomosis).
Recovery: Eating is usually reintroduced gradually, and patients are encouraged to move early. The length of stay varies with the approach and the patient's condition.
Possible risks: Bleeding, wound or abdominal infection, anastomotic leak, temporary slowing of the bowel (ileus), incisional hernia, blood clots and risks of anaesthesia.
Documented experience: Listed in Dr. Naser Dib's CV and professional profile among his oncological and colorectal procedures.
