Morbidity after Total Gastrectomy: Analysis of 238 Patients

Abstract

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 postoperative outcomes on 238 patients who underwent total gastrectomy with curative intent, from 2003 to 2012, were reviewed by a dedicated surgeon chart reviewer to establish 90-day patterns of adverse events.

Results: Of the 238 patients with stage I to III gastric adenocarcinoma who underwent curative-intent total gastrectomy, the median age was 66 years, and 68% were male. Median body mass index was 28 kg/m(2), and 68% of patients had at least 1 medical comorbidity. Forty-three percent of our patients received neoadjuvant chemotherapy, and 34% received postoperative adjuvant chemotherapy. Over the 90-day study period, 30-day mortality was 2.5% (6 of 238), and 90-day mortality was 2.9% (7 of 238). At least 1 postoperative 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.

Conclusions: This analysis has defined comprehensive 90-day patterns in postoperative adverse events after total gastrectomy with curative intent in a Western population. This benchmark allows surgeons to measure, compare, and improve outcomes and informed consent for this surgical procedure.
