omentectomy

In patients with abdominal malignant tumors and peritoneal metastases, resection of the omentum and lymph node dissection are required at the same time as the corresponding organ resection. Omentum is a common site for ovarian cancer metastasis. Routine resection of the omentum is not only beneficial for postoperative chemotherapy or radiotherapy, but also reduces the formation of ascites, prevents adhesions or forms a mass in the intestinal tract, and significantly improves ovarian cancer. The patient's 5-year survival rate. Treatment of diseases: peritoneal metastases Indication Omental metastasis and the like. Omentectomy is an important part of surgical treatment of ovarian cancer. The resection range is generally at the lower edge of the transverse colon. Preoperative preparation X-ray examination: used to determine the location of the large omental mass. Laparoscopy: combined with biopsy to determine the cause and nature of the lesion. Surgical procedure Into the abdominal cavity, the transverse colon is proposed to incision, the omentum is tightened, and the transverse colon is pulled down, so that the peritoneal transition between the omentum and the transverse colon is exposed, and the posterior and transverse colonic peritoneum of the greater omentum is followed along the colon. The transition is cut from right to left until the spleen of the colon. The gauze is bluntly separated, and the omentum is continued to the underside and the front of the colon, and is separated from the peritoneum. Cut the anterior lobe of the greater omentum and enter the omental sac. When separating to the left of the colon, the lower part of the gastric spleen ligament and the left ventricle and vein of the gastric retina are separated and separated. The spleen colon ligament can also be severed when needed. When separating to the right of the colon, cut and ligation of the right movement and vein of the gastric retina, and separate the omentum attached to the pancreatic head and duodenum, taking care not to injure the deep colonic veins and veins. . At this point, the omentum separation is complete. complication For the resection of primary malignant tumors and metastatic carcinoma of the greater omentum, it is often palliative, and the prognosis is extremely poor, but after resection, the burden of intra-abdominal tumors can be reduced to prevent the production of ascites.
