ObjectiveTo explore the effect of body mass index (BMI) on therapeutic effect and surgical risk of esophagectomy. MethodsWe retrospectively collected the data of 494 patients who underwent esophagectomy in West China hospital of Sichuan University between March 2014 and March 2015. According to BMI, all patients were allocated to three groups: an obesity group (BMI≥25 kg/m2) of 74 patients, a normal weight group (18.5 kg/m2≤BMI < 25 kg/m2) of 345 patients, and a low weight group (BMI < 18.5 kg/m2) of 75 patients. ResultsThere were no statistical differences in the intraoperative blood loss (213.33±55.10 ml vs. 218.90±60.76 ml vs. 217.30±61.10 ml), operation time (197.07±52.47 min vs. 208.35±96.84 min vs. 182.84±63.06 min), incidence of postoperative complication (38.7% (29/75) vs. 43.2% (149/345) vs. 39.2% (29/74), the number of resected lymphnodes (l16.18±6.64 vs. 16.68 ±8.48 vs. 8.48±8.26), and the number of the metastatic lymphnodes (1.42±2.53 vs. 1.32±2.51 vs. 2.45±4.08) among the low weight group, the normal weight group, and the obesity group. ConclusionObesity and low weight do not increase the surgical risk and influence the surgical outcome. Therefore, obesity and low weight should not interfere with the operative choice of patients with esophageal cancer.
ObjectiveTo investigate the efficacy of total thoracoscopy (VATS) lobectomy and the thoracotomy for the treatment of benign lung disease. MethodsWe retrospectively analyzed the clinical data of 70 patients with benign lung diseases in the First People's Hospital of Qujing between January 2012 and September 2013. According to the surgical way, the patients were divided into two groups including a total VATS group involved in 35 patients with 25 males and 10 females, aged 18 to 71 years, mean age of 41.3±6.4 years and a thoracotomy group involved in 35 patients with 26 males and 9 females, aged 19 to 72 years, mean age of 42.4±5.6 years. Then we compared the efficacy of the two groups. ResultsThere was no statistical difference (P > 0.05) in operative time and postoperative survival rate comparison. While in the total VATS group, the total thoracoscopic incision length, bleeding volume or pain time, postoperative day time of analgesia, thoracic drainage volume, postoperative drainage tube pulling time and hospitalization time were all lower than those in the thoracotomy group with statistical differeces (P < 0.05). ConclusionThe thoracoscopic lobectomy for treatment of benign pulmonary lesions is superior to the conventional thoracotomy with much less bleeding and pain, more faster postoperative recovery and less impact on the patient's body. It's suitable for clinical application in normal hospital.
