Abstract

PURPOSE
The aim of this study was to establish an anthropometric reference of the stomach for gastric cancer surgery and a modeling formula to predict stomach length.
MATERIALS AND METHODS
Data were retrieved for 851 patients who underwent total gastrectomy at the Seoul National University Hospital between 2008 and 2013. Clinicopathological data and measurements from a formalin-fixed specimen were reviewed. The lengths (cm) of the greater curvature (GC) and lesser curvature (LC) were measured. Anthropometric data of the stomach were compared according to age, body weight, height (cm), and body mass index. To predict stomach length, two multiple regression analyses were performed.
RESULTS
The mean lengths of the GC and LC were 22.2±3.1 cm and 16.3±2.6 cm, respectively. The men's GC length was significantly greater than the women's (22.4±3.1 cm vs. 21.2±2.9 cm, P=0.003). Patients aged >70 years showed significantly longer LC than those aged <50 years (16.9±2.9 cm vs. 15.9±2.4 cm, P=0.002). Patients with body weights >70 kg showed significantly longer GC than those with body weights <55 kg (23.0±2.9 cm vs. 21.4±3.2cm, P<0.001). In the predicted models, 4.11% of the GC was accounted for by age and weight; and 4.94% of the LC, by age, sex, height, and weight.
CONCLUSIONS
Sex, age, height, and body weight were associated with the length of the LC, while sex and body weight were the only factors that were associated with the length of the GC. However, the prediction model was not sufficiently strong.

  Fig. 1 The lengths of the GC and LC were measured. (A) Opening along the GC, the length of the straight line between the esophagogastric junction and the pylorus was measured for the LC and that between the pylorus and the apex of fundus for the GC. (B) Opening along the LC, the length of the straight line between the esophagogastric junction and the pylorus was measured for the GC and the length of circumference line between the pylorus and the esophagogastric junction along the cut side for the LC. GC = greater curvature; LC = lesser curvature.

  Fig. 2 To examine the validity of the prediction models, 112 new patient cases who underwent total gastrectomy from 2014 to 2015 were predicted by the models, and the predictions were compared with the lengths measured on the specimens. (A) The length of GC compared to the difference between predicted and observed values. (B) The length of LC compared to the difference between predicted and observed values. The limit of agreement was about 5 in GC and LC. GC = greater curvature; LC = lesser curvature.

  Fig. 3 External validation of the prediction model using 29 new cases who underwent total gastrectomy. The correlation between actual size and the regression formula analyzed by pearson correlation coefficient. The greater curvature than lesser curvature showed the correlation between the regression formula and actual stomach.
