Surgical quality control is a crucial determinant of evaluating the tumor efficacy. We assess the ClassIntra grade for quality control and oncological outcomes of robotic radical surgery for gastric cancer (GC).

Gastric cancer (GC) is the fifth most common malignant tumor worldwide and the fourth leading cause of cancer-related deaths. Surgery remains the cornerstone of GC treatment, and there is a significant lack of research on iAE compared with postoperative complications. Owing to the influence of reporting and cultural acceptance, there have been issues of inadequate reporting and non-standardized practices regarding iAE reporting.

The previously reported laparoscopic results showed that the ClassIntra grade is an effective prognostic and surgical quality control index for laparoscopic radical surgery for gastric cancer therefore it could be included in routine hospital care and surgical quality control. (DOI: 10.1097/SLA.0000000000005727). Here, iAEs in patients who underwent robotic radical gastrectomy significantly correlated with the occurrence of postoperative complications and a poor long-term prognosis. Therefore, utilization and inclusion of ClassIntra grading as a crucial surgical quality control and prognostic indicator in the routine surgical quality evaluation system are recommended.

Inclusion Criteria:

• Patients diagnosed with gastric adenocarcinoma through pathology;
• Preoperative chest radiograph, abdominal ultrasonogram, and full abdominal CT examination showed no distant metastasis to the liver, lungs, or abdominal cavity;
• Patients who underwent robotic radical gastrectomy.

Exclusion Criteria:

• Intraoperatively existing distant metastases
• Neoadjuvant chemotherapy
• Missing general and video data.

This study included 366 patients who underwent robotic gastrectomy at the Department of Gastrointestinal Surgery, Fujian Medical University Union Hospital, between August 2016 and September 2019, where over 800 gastrectomies were performed annually for patients with GC.
