ObjectiveTo analyze the effect of different drainage modes on the postoperative thoracic drainage after video-assisted thoracoscopic surgery for radical resection of lower lung carcinoma.MethodsA total of 183 patients with non-small cell lung cancer who received biportal thoracoscopic anatomical lower lobectomy combined with mediastinal lymph node dissection in the First Affiliated Hospital of Xi'an Jiaotong University from August 2017 to August 2019 were enrolled, including 113 males and 70 females, aged 31-77 (56.5±6.4) years. The patients were randomly divided into three groups, including an anterior axillary line group, a mid-axillary line group and a modified anterior axillary line group. Clinical efficacy of the three groups was compared.ResultsNo significant difference among these three groups in terms of gender, age, surgical site, pathological type, pathological staging, postoperative chest wall subcutaneous emphysema, postoperative pain score, and postoperative hospital stay was found (P>0.05). There were significant differences among the patients in terms of postoperative pleural effusion, re-insertion of chest tube or aspiration, total liquid quantity of thoracic drainage, drainage time and chest wall incision stitches time (P<0.05). The anterior axillary line group had higher risk of postoperative pleural effusion than the other groups (P<0.05). The occurrence of postoperative pleural effusion and rate of reposition of chest tube or aspiration were significantly reduced in the modified anterior axillary line group (P<0.05).ConclusionChest drainage tube with large diameter (24F) in the 5th intercostal space of the anterior axillary line combined with another micro-tube (8.5F) in the 7th or 8th intercostal space of the inferior scapular angle line can shorten drainage time to reduce postoperative pain, reduce the occurrence of postoperative pleural effusion, and shorten the time of surgical incision stitches.
ObjectiveTo investigate the relation between histology type and prognosis of gastric cancer.MethodsThe clinical database of 311 patients who underwent surgical resection for gastric cancer in our hospital, between 2000 and 2004, was retrospectively reviewed and analyzed with SPSS 13.0. ResultsLymph node metastasis, tumor invasion depth, and Borrman type of gastric cancer were related with histology type （χ2 test, Plt;0.05）. KaplanMeier survival analysis was used to compare the survival rate and showed that there was a significant difference between highly/moderately differentiated cancers and the poorly differentiated (Plt;0.05), while there was no statistical difference between those patients with same invasion depth （Pgt;0.05）. ConclusionThe prognosis of gastric cancers with same invasion depth is same regardless of their histology types.
Objective To investigate the risk factors for insulin resistance (IR) after selective operation in the department of general surgery. Methods Two hundred and sixty-three patients including 122 males and 141 females after selective operation between March 2009 and October 2009 in The First Affiliated Hospital of Xi’an Jiaotong University were studied. Sex, age, histories of smoking and drinking, hypertensive disease, history of operation, height, weight, waist circumference, anesthesia method, operation duration, operation method, and volumes of transfusion and liquid injection during operation were recorded. The fasting blood glucose (BG) and fasting plasma insulin (INS) were tested for selectively operative patients on day 1 before and after surgery. Insulin resistance index (HOMA-IR) and the index of insulin secretion (HOMA-β) were calculated with homeostasis model assessment (HOMA). Logarithms of HOMA-IR (lnHOMA-IR) was taken because that HOMA-IR was not normal distribution. Results The levels of fasting BG, fasting plasma INS, and lnHOMA-IR on day 1 after operation were higher than those on day 1 before operation (Plt;0.001). IR was correlated with patients’ sex (P=0.002), the history of smoking (P=0.033), waist circumference (P=0.000), operation method (P=0.007), and the volume of liquid injection during operation (P=0.001). A significant elevation of the change of lnHOMA-IR level was found between abdominal and nonabdominal surgery (Plt;0.001). Conclusions IR occurs in selectively operative patients in the department of general surgery. It is helpful for depressing IR to control the intensity of surgery.
ObjectiveTo compare and analyze the short-term efficacy of different surgical methods for Siewert type Ⅰ and type Ⅱ esophagogastric junction carcinoma.MethodsWe selected 82 patients who accepted radical resection of esophagogastric junction carcinoma from March 2015 to March 2018 in our department, including 53 males and 29 females, aged 48-72 (61±6) years. The patients were divided into four groups according to the surgical method: a left thoracotomy group (n=14), a laparoscopic left small thoracotomy group (n=33), a thoracoscopic Ivor-Lewis group (n=17), and a thoracoscopic McKeown group (n=18). Their clinical characteristics, operative situations, postoperative complications and survival rate were analyzed.ResultsAmong the four groups, the left thoracotomy group cost the shortest operation time, followed by laparoscopic left small thoracotomy group, thoracoscopic McKeown group and thoracoscopic Ivor-Lewis group. The thoracoscopic McKeown group/laparoscopic left small thoracotomy group had the least bleeding. The fewest lymph nodes were dissected in the left thoracotomy group and the most in the thoracoscopic McKeown group. The laparoscopic left small thoracotomy group had the lowest total complication rate and the incidence of pneumonia and arrhythmia among the four groups (P<0.05). There was no significant difference in survival rate among the four groups (P>0.05).ConclusionFor Siewert type Ⅰ and type Ⅱ esophagogastric junction carcinoma, thoracoscopy combined with laparoscopic radical resection is safe and reliable. Laparoscopic left small thoracotomy has the advantages of minimal invasiveness and complete lymph node dissection, especially for the patients with poor cardiopulmonary function, which will significantly shorten operation time and reduce postoperative complications, so it is worth to be popularized.
