- Bowel movement disorders (constipation, incontinence)
- Diseases of the anus (hemorrhoids, stretch marks, fistulas)
- Laparoscopic and minimally invasive colon surgery

Pioneer in Orthopedic Surgery - International First
Dr. Ioannis Bolanis is one of the few surgeons in Greece who perform transsphincteric resection for rectal cancer at a distance of up to 1 cm from the sphincter, without requiring a permanent colostomy.
In fact, he was the first in Greece and one of the first internationally to apply the pull-through delayed anastomosis method. With it, both the temporary and the permanent unnatural seat (colostomy) in rectal cancer are definitively avoided. This innovative technique has been published in English by the Hellenic Surgical Society and is considered a benchmark in modern rectal surgery.

Intestinal and Rectal Diseases Clinic
The Clinic for General & Laparoscopic Surgery of the Intestine and Anus was created with the aim of providing a high level of specialized services to patients with problems of the gastrointestinal system – that is, the small intestine, large intestine and anus.
Specialized operations performed at the Clinic:
- Avoidance of colostomy (despite the nature of the seat) in patients with rectal cancer close to the sphincter (up to 1–2 cm): Among the first internationally, we developed and implemented the pull-through delayed anastomosis method, which allows avoiding even a temporary stoma, offering quality of life to patients.
- Specialized operations in inflammatory and genetic diseases of the colon: – Total colectomy and J-Pouch type anastomosis for ulcerative colitis and familial adenomatous polyposis (FAP). – Sphincter reconstruction in cases of faecal incontinence from injury or degenerative damage.
- Treatment of diseases of the anus with modern minimally invasive techniques: – Haemorrhoids (THD, LHP® techniques, etc.) – Ring fissure – Peripheral fistulae – Coccyx cyst (EPSiT, FiLaC® methods, etc.) – Warts and other proctological diseases
- Comprehensive general surgery services with laparoscopic and open techniques: – Hernias (inguinal hernia, umbilical hernia, postoperative hernia) – Cholecystectomy (bile) – Appendicectomy – Cysts, lipomas and other soft tissue operations
