Two reasons for bleeding during laparoscopic gastric cancer surgery

In recent years, with the continuous development of medical technology, the scope of laparoscopic surgery has expanded from early gastric cancer to advanced gastric cancer. While achieving therapeutic effects, various complications are inevitable. The most common one is bleeding. There are two main reasons.

1. Improper endoscopic clearance of perigastric lymph nodes

Perigastric lymph node clearance is the key to laparoscopic-assisted radical gastrectomy. Laparoscopic treatment of gastric cancer requires doctors to have skilled operation skills and rich experience in abdominal surgery, especially during intraoperative clearance. Gastric cancer surgery is relatively complex and time-consuming. If the doctor is not skilled in operation and causes vascular damage, or cannot deal with emergencies skillfully and calmly, it is easy to cause intraoperative or postoperative bleeding. If there is small blood vessel bleeding or tissue oozing during the operation, bipolar electrocoagulation clips can be used to stop bleeding. In case of loose tissue, the tearing function of the bipolar electrocoagulation clip can be fully utilized to avoid massive bleeding.

2. Improper handling of perigastric vessels under endoscopy

Laparoscopic gastric cancer surgery is the same as traditional open surgery. Although the operation methods are different, both of them aim to achieve radical cure. Laparoscopic gastric cancer surgery uses long instruments to perform long-distance operations under limited field of view. Because the puncture hole is the fulcrum, sometimes the operator's lever arm is short when operating in deep areas. It is difficult to align the tip of the instrument in the surgical field with the blood vessel, which inevitably causes tearing and bleeding. It is even more difficult when the blood vessel is slightly deformed, twisted and free. If there is intra-abdominal bleeding after surgery, it is mostly caused by incomplete coagulation during surgery, incomplete or detached blood vessel clamping, poor anastomosis technology or improper use of the stapler.
