Background: There is a prevailing belief that both obesity and abdominal shape influence abdominal accessibility, and thus affect short-term surgical outcomes of gastric cancer surgery.

Methods: We measured the thickness of subcutaneous fat (SCF), abdominal anterior-posterior diameter (APD), transverse diameter (TD), and intra-abdominal fat volume (IFV) at the umbilicus level by using the abdominal CT scans of 291 gastric cancer patients who had undergone subtotal gastrectomy and D2 lymph node dissection. Clinicopathological factors including body mass index (BMI), APD, TD, IFV, and SCF and surgical outcomes, i.e., dissected lymph node number, morbidity, and mortality were analyzed.

Results: SCF thickness, APD, TD, IFV, and BMI mean values were 20.0 mm (range 2.0–64.0), 188.4 mm (range 128.0–332.0), 301.4 mm (range 160.0–651.0), 198.3 mm2 (range 123.4–312.1), and 23.9 kg/m2 (range 16.6–34.6), respectively. In male patients, APD was found to correlate with the number of retrieved lymph nodes (P = 0.045). Whereas in female patients, this was not the case (P = 0.093). Twenty-one patients experienced postoperative complications but no postoperative mortality occurred. Female patients who experienced postoperative complications had higher APD (32.9 ± 10.0 mm versus 26.1 ± 7.9 mm, P = 0.044) and BMI (27.3 ± 4.1 kg/m2 versus 24.3 ± 3.5 kg/m2, P = 0.049) values than those who did not.

Conclusions: We conclude that obesity and abdominal shape of gastric cancer patients both influence the short-term surgical outcomes of subtotal gastrectomy with D2 lymph node dissection.
