What are the methods of omental resection

summary

My father suffered from gastric cancer last year. The doctor communicated with us that we need not only subtotal gastrectomy, but also omental resection. Let's popularize the science of omental resection.

What are the methods of omental resection

First, patients with abdominal malignancies and peritoneal metastases need omental resection and lymph node dissection at the same time of corresponding organ resection. Omentum is a common site of ovarian cancer metastasis. Conventional resection of omentum is not only conducive to postoperative chemotherapy or radiotherapy, but also can reduce ascites formation, prevent adhesion or formation of mass compression of intestinal tract and cause intestinal obstruction, and significantly improve the 5-year survival rate of patients with ovarian cancer.

Second: omentum belongs to a kind of peritoneum, the peritoneum moves from the parietal layer to the visceral layer, or from one organ to another, forming a double-layer peritoneal structure. Blood vessels, nerves and lymphatic vessels often run between the two layers of peritoneum. The greater omentum is the peritoneum connecting the greater curvature of the stomach to the transverse colon, covering the jejunum and ileum in an apron shape.

Third, the peritoneum has a strong ability of repair and healing. On the one hand, it has some defensive or phagocytic cells. On the other hand, when the abdominal organs are infected, the peritoneum formation, especially the greater omentum, can quickly tend to the infected lesions, wrap the lesions or produce adhesion, so that the lesions are limited and do not spread quickly.

matters needing attention

Omental resection is the corresponding operation for abdominal tumor patients, so if doctors let patients do the corresponding operation, do not panic, the recurrence rate of this operation is very low, and the peritoneum has strong repair and healing ability.
