Manna-Magatha Operation

The Mann-Magath operation was developed by American surgeon Francis Chan Mann (1887–1962) and British surgeon Thomas W. Magath (1902–1978). In 1940, they proposed surgery to treat patients with stomach cancer.

Manna-Magat surgery involves gastric resection, removing part of the stomach with the tumor and creating an anastomosis between the remaining part of the stomach and the small intestine. This operation saves the patient's life and improves his quality of life.

The operation is performed under general anesthesia and includes several stages:

  1. Preparatory stage: before the operation, the patient must undergo an examination, including blood and urine tests, abdominal ultrasound and chest x-ray.
  2. Anesthesia: the patient is under general anesthesia, which allows the operation to be performed without pain and stress.
  3. Incision: The surgeon makes an incision in the upper abdomen to access the stomach.
  4. Tumor removal: The surgeon removes the part of the stomach containing the tumor.
  5. Anastomosis: The surgeon connects the remaining part of the stomach to the small intestine to provide nutrition to the patient.
  6. Completion of surgery: The surgeon closes the incision, applies sutures, and provides postoperative care to the patient.

After the operation, the patient must remain in the hospital under the supervision of doctors for several days. He may experience discomfort and pain in the abdomen, but this usually goes away after a few days.

In general, Manna-Magat surgery can be considered successful if it allows you to remove the tumor and save the patient’s life. However, like any other surgery, there is a risk of complications such as bleeding, infection and other problems. Therefore, before performing the operation, it is necessary to carefully assess the patient’s condition and discuss with him all possible risks and benefits.



The Mann-Magath operation belongs to the German Association of Surgeons and involves the surgical treatment of Watson's triad. Watson's triad is a pathological condition associated with pathological expansion of the lumen of the esophagus, characterized by dilation, edema and degenerative changes in the mucous membrane of the cardia or cardiac part of the stomach. In the international classification of diseases it is found under the code Q40. This disease is characterized by prolonged stagnation of food in the lower esophagus and the absence of its normal movement into the stomach. The water-electrolyte balance is disrupted, and inflammatory changes in the gastrointestinal tract occur. There are two types of the disease - Payra's disease and I's disease.
