AB42. Analysis for reoperation on gastric cancer patients (clinical analysis of 141 cases)

Objective: To explore various relevant risk factors on reoperation on gastric cancer patients and reduce the rate of reoperation.

Methods: By analyzing retrospectively 11,616 cases that were diagnosed with gastric cancer and had operation in our hospital from Jan. 1989 to Dec. 2010, of which, unplanned reoperations is 141, to evaluate their basic information and figure out the various influencing factors on reoperation.

Results: The incidence of reoperation is 1.21% (141/11,616) in this study. The average time between the primary operation and reoperation is 15.89±15.20 days. Diabetes, anemia, hypoproteinemia, or with abdominal surgery history, blood transfusion, or blood loss ≥400 mL in primary operation lead the incidence of reoperation going up. The incidence of reoperation in the group of proximal gastrectomy and total gastrectomy is higher than that of thoracic cardiectomy and distal gastrectomy. The incidence of reoperation is not related with gender, age, cardiopulmonary disease, adopting stapling technique or using anti-adhesion agentia in primary operation obviously. Anastomotic leakage is the key factor to high incidence of reoperation and mortality in all complications.

Conclusions: Diabetes, anemia, hypoproteinemia, abdominal surgery history, blood transfusion, or blood loss ≥400 mL in primary operation are the risk factor of the incidence of reoperation rising. The reoperations are more likely to happen to patients who had proximal gastrectomy and total gastrectomy. Anastomotic leakage is the most dangerous complications to lead to reoperation and death.
