Brief Summary

Gastric cancer is still one of the main health care issue and gastrectomy with lymph node dissection is the only chance to be cure. Trials show that the postoperative course differs significantly between eastern and western centers, as well as between clinics within Russian Federation. Postoperative 30-day postoperative mortality after gastric cancer surgery ranges from 1% to 5%, and postoperative complication rates range from 10% to 40%. To improve the quality of further studies and recommendations for standardization of surgical treatment of gastric cancer and its complications, there is a need to study the differences in 90-day postoperative morbidity and mortality in different clinics and centers of the Russian Federation.

Detailed Description

According to 2018 World Health Organization (WHO) data, gastric cancer is the fourth most common malignant disease and the third leading cause of cancer-related deaths worldwide. Surgery with lymphadenectomy remains the standard of care. Despite significant changes in gastric cancer treatment protocols, surgery is still associated with high risks of complications, with rates varying from clinic to clinic. And currently, the use of multimodal treatments and standardization of surgical procedures are proposed as strategies to improve outcomes. In addition, the use of laparoscopic and robotic techniques have been proposed to provide better short-term results compared to open surgery and comparable long-term oncological outcomes. Randomized trials show that the postoperative course differs significantly between eastern and western centers, as well as between clinics within Russian Federation. Postoperative 30-day postoperative mortality after gastric cancer surgery ranges from 1% to 5%, and postoperative complication rates range from 10% to 40%. While mortality is easier to quantify, there are no standardized criteria for calculating postoperative complication rates. To improve the quality of further studies and recommendations for standardization of surgical treatment of gastric cancer and its complications, there is a need to study the differences in 90-day postoperative morbidity and mortality in different clinics and centers of the Russian Federation.

Primary Outcome Measures
NameTimeMethod
the type of complications and the incidence of itwithin 90 days after operation

the types of complication is classified into as follows: anastomotic leak, postoperative bleeding requiring invasive treatment, other complications requiring re-intervention or other invasive procedure, postoperative bowel obstruction, postoperative pancreatic fistula, duodenal leak, gastrostasis, postoperative pancreatitis, postoperative bowel perforation or necrosis, non-surgical infections, pleural effusion requiring drainage, respiratory failure requiring reintubation, acute renal failure requiring hemofiltration/dialysis, need for prolonged intubation, need for tracheostomy, need for cardiopulmonary resuscitation, pulmonary embolism, pneumothorax requiring treatment, myocardial infarction, acute myocardial failure, cardiac dysrhythmia requiring invasive treatment, stroke, acute liver dysfunction, other complications.

Each complication will be graded according to Clavien-Dindo classification. Re-admission or visiting emergency room will be checked and recorded.
