Résumé
OBJECTIVES: The literature concerning relations between thoracic surgery and digestive motility is poor. The aim of our study was two-fold: (i) to show a link between thoracic surgery and gastric distension and (ii) between post-operative pneumoniae and gastric distension. METHODS: A retrospective analysis was conducted in 262 patients who had undergone a thoracotomy for lung resection between January and December 2007. Transverse diameter of the stomach was measured on chest X-rays performed on Day 0 and on Day 1. Gastric distension was defined as a ratio (R) D1/D0 higher than 1.3 (min: 0.5; max: 4.1). Three groups were defined: Group 1 (absence of distension) R < 1.3; Group 2 (moderate distension) 1.3 /= 2.3. International criteria of the Center of Disease Control were used to define pneumonia. Appropriate statistical tests were carried out. RESULTS: There were 73 women (27.9%) and 189 men (72.1%), ages ranged from 20 to 83 years (average: 59.9 years). As for gastric distension, 194 patients (74.04%) constituted Group 1, 53 (20.23%) Group 2 and 15 (5.73%) Group 3. Pneumonectomy significantly increased the incidence of gastric distension on Day 1 (P = 0.04). The side, mediastinal lymphadenectomy and personal medical past history of upper gastro-intestinal tract surgery had no statistically significant influence on the incidence of gastric distension. Univariate analysis showed that patients with gastric distension on D1 had significantly more infectious pneumonia on Day 5 (P < 0.0001): 16 (8.25%) patients in Group 1, vs 14 (26.41%) in Group 2 and 7 (46.67%) in Group 3. Furthermore, on Day 5, 33.33% (n = 8) of pneumectomies had pneumonia, against 12.18% (n = 29) of patients who had undergone another type of surgery (P = 0.01). On multivariate analysis, gastric distension was an independent predictive factor of infectious pneumonia on Day 5 (Group 3: odds ratio = 16.127 [4.267; 60 959], P < 0.0001). CONCLUSIONS: We established, in our cohort of patients, a link between pneumonectomy and gastric distension on Day 1 and infectious pneumonia on Day 5. A prospective multicentre study would be desirable to verify these data.
