    The Abdominoperineal Excision (Miles' Operation)

    The Abdominoperineal Excision (Miles' Operation)

    Like the rest of the intestine, the muscular walls of the rectum are lined with mucous membranes. When it is filled with faeces, its walls tighten, which activates the receptors of the nervous system, which in turn innervate the walls of the rectum, causing the urge to empty it. Often, when emptying does not occur, faeces return to the intestines, where fluids are absorbed.

    Among the diseases to which the rectum is susceptible: cancer; the formation of “pockets” at the end of the rectum (diverticulitis), the pollution of which creates pressure that delays the flow of blood to the walls of the intestine due to the long-term accumulation of hardened faeces; inflammation of the colon, which can cause ulcers and Crohn’s disease; intestinal obstruction and intestinal ischemia (lack of blood in the intestine). In the case of diverticulitis or inflammation of the colon with ulcers in the rectum, damage or perforation can form. 

    In such cases, it may be necessary to remove the damaged part of the intestine or rectum. In most cases, after resection, the rectum resumes normal functioning. In the most difficult cases, a complete resection of the colon and rectum (Miles operation) may be required.

    Preparation for surgery 

    In the case of cancer, an operation is performed, the volume and location of which depends on the characteristics of the tumour. Often, chemotherapy and radiation therapy will be performed before and after surgery. It is impossible not to note the extreme importance of early diagnosis of the disease and factors contributing to its development (polyps). The sooner cancer is detected, the more effective the treatment and the greater the chance of recovery.

    When removing small sections of the intestine due to various diseases or cancer detected at an early stage, the patient is expected to recover completely within 6-8 weeks, without any complications. The speed of recovery depends on the general condition of the patient before surgery.

    Surgery 

    In the presence of more extensive cancerous tumours or injuries caused by certain intestinal diseases, the operation requires an abdominal incision and is performed under complete anaesthesia. A surgeon specializing in intestinal diseases will also remove the lymph nodes located next to the damaged area and send them for histological examination to determine how much cancer has spread. The choice of a specific tumour removal procedure will depend on its location.
