Endoscopic colorectal surgery

Minimally invasive treatment of diseases of the colon and rectum, for faster recovery and smaller scars.

What is it?

Endoscopic colorectal surgery covers minimally invasive operations on the colon and rectum: resection of a diseased segment of colon, treatment of complicated diverticula, excision of extensive lesions. It relies on fine instruments and a high-definition camera introduced through small incisions or through natural orifices. This approach reduces post-operative pain, shortens the hospital stay and allows a faster return of bowel function and daily activities, while offering the same quality of treatment as conventional surgery. The choice of technique is tailored to each patient after a complete work-up. At Clinique Pasteur Tunis, minimally invasive colorectal surgery is performed by experienced digestive surgeons, with a complete imaging and endoscopy platform on site. The patient pathway is organized from the initial consultation through to post-operative follow-up, with attentive support at every stage.

When is it indicated?

Complicated or recurrent diverticular disease

When small pouches that form on the colon become repeatedly infected, removing the weakened segment puts an end to the attacks.

Colon or rectal polyps that cannot be removed by simple colonoscopy

When a polyp is too large to be removed during a colonoscopy, a minimally invasive resection is proposed.

Colorectal tumors requiring surgical resection

When a tumor is discovered, removing the affected segment of intestine is the gold-standard treatment.

Certain inflammatory bowel diseases resistant to medical treatment

When the inflammation no longer responds to medication, surgery removes the most affected portion to relieve the patient.

Rectal prolapse requiring surgical correction

When the rectum descends abnormally, the operation repositions and secures it to restore everyday comfort.

Preparation

1Complete work-up: colonoscopy, imaging and blood tests
2Anesthesia consultation
3Bowel preparation according to the instructions provided
4Fasting for 6 hours before the operation
5Stopping or adjusting anticoagulants according to medical advice

Procedure

1

General anesthesia

2

Introduction of the camera and instruments through small incisions

3

Mobilization and resection of the affected segment of colon or rectum

4

Restoration of digestive continuity by suturing or stapling

5

Leak testing and closure of the incisions

6

Post-operative monitoring with gradual resumption of eating

Duration

2 to 4 hours depending on the operation

Aftercare & Recovery

Bowel function usually returns within a few days, along with a gradual return to eating. The hospital stay is shorter than after conventional surgery and the scars are discreet. The surgical specimens undergo histopathological analysis, the results of which guide follow-up.

Risks and side effects

Temporary bowel disturbances during the recovery period
Fistula or anastomotic leak, a rare complication subject to careful monitoring
Wound infection, uncommon with the minimally invasive approach
Conversion to open surgery if necessary, in the patient's best interest

These risks remain rare. Your surgeon will inform you in detail before the procedure.
