This website provides you with information on the most common conditions and their surgical treatments. It does not, however, substitute the detailed advice that would be given to you during a personal consult in any way.


Colon cancer is a collective term for different types of cancer to the small intestine, large intestine and the rectum.

Hemorrhoids are swollen blood vessels in the rectum, located in the lower part of the rectum and the anus.

Bowel obstruction refers to a blockage of the small or large intestine.

The causes of both diverticulosis as diverticulitis are unclear.

Diverticulosis is presumed to be attributable to a low-fiber diet.

Gallstones are accumulations of crystals in the gallbladder or the biliary system.

An inguinal hernia or hernia inguinalis is a condition consisting of a bulging of the peritoneum in the femoral region causing the organs normally located in the abdominal cavity to herniate.

A rectocele is a hernia of the front wall of the rectum into the back wall of the vagina
