Background
Surgical quality improvement requires well-defined benchmarks and accurate reporting of postoperative adverse events, which have not been well defined for total gastrectomy.
Study Design
Detailed post-operative outcomes on 238 patients who underwent curative intent total gastrectomy from 2003 – 2012 were reviewed by a dedicated surgeon chart reviewer to establish the 90-day patterns of adverse events.
Results
Of the 238 patients with stage I – III gastric adenocarcinoma who underwent curative intent total gastrectomy, the median age was 66, and 68% were male. Median body mass index was 28, and 68% of patients had at least one medical comorbidity. Forty three percent of our patients received neoadjuvant chemotherapy, and 34% received post-operative adjuvant chemotherapy. Over the 90 day study period, 30-day mortality was 2.5% (6/238), and 90-day mortality was 2.9% (7/238). At least one post-operative adverse event was documented in 62% of patients, with 28% of patients experiencing a major adverse event requiring invasive intervention. The readmission rate was 20%. Anemia was the most common adverse event (20%), followed by wound complications (18%). The most common major adverse event was esophageal anastomotic leak, which required invasive intervention in 10% of patients.
Conclusion
This analysis has defined comprehensive 90-day patterns in post-operative adverse events following curative intent total gastrectomy in a Western population. This benchmark allows surgeons to measure, compare, and improve outcomes and informed consent for this surgical procedure.
