Objective To compare the pulmonary complications between the double lumen tube and the single lumen tube,and to determine whether there are objective advantages of one over the other in one-lung ventilation during minimally invasive esophagectomy(MIE).Methods From January 2012 to November 2013,165 patients with esophageal cancer received combined thoracoscopic and laparoscopic esophagectomy with anastomosis in the neck.All clinical data were retrospectively reviewed.Results Between the single lumen tube and the double lumen tube:patients with pulmonary infection is 11 (16.42％),34(34.69％) (P =0.010).The average intubation time is(1.45 ±0.22)min,(6.53 ±0.59) min,P =0.000.The number of harvested lymph nodes of total is (42.76 ± 18.11) and (34.32 ± 15.80),P =0.002.The number of harvested lymph nodes of the cervix and the left laryngeal recurrent nerve chain was (3.19 ± 2.53) and (1.30 ± 2.14),P =0.000.Conclusion In the minimally invasive esophagectomy,single lumen tube is simpler and easier than the double lumen tube,and with the low incidence of postoperative pulmonary complications,at the same time there are more advantageous in the meditational lymph nodes cleaning.

Objective To cultivate specialist nurses to perform preoperative stoma site marking in patients to receive enterostomy and improve the rate of preoperative stoma site marking and the ability of preoperative stoma site marking in specialist nurses. Methods The rate of preoperative stoma site marking in 148 patients from July 2016 to October 2016 was investigated and the reason of not receiving preoperative stoma site marking was analyzed. Nineteen primary nurses were trained to perform preoperative stoma site marking instead of the traditional pattern which was performed by enterostomy therapist and physician. The training included the criteria of preoperative stoma site marking, difficult preoperative stoma site marking, demonstration, group exercises, theoretical and operational assessment. The preoperative stoma site marking of 156 patients were performed by specialist nurses from November 2016 to February 2017.Then,the rate of preoperative stoma site marking,accuracy of stoma location,and knowledge of preoperative stoma site marking were compared between the traditional and new management pattern. Results The preoperative stoma site marking rate was 91.89%(136/148)and the accuracy rate was 94.12%(127/136)in traditional management pattern.The lack of enterostomy therapist, surgery performed on weekends and emergency surgery were the reasons that preoperative stoma site marking was not performed.After changing the management pattern,the preoperative stoma site marking rate was increased to 98.72%(154/156) and there was a significant difference between them (χ2=8.06, P <0.05).The accuracy of localization was decreased to 92.86%(143/154),but there was no significant difference between them(χ2=0.03,P>0.05).The rate of acquiring preoperative stoma site marking knowledge in nurses was increased from 8/19 to 18/19 with a significant difference(χ2=12.18,P<0.01). Conclusions The pattern of preoperative stoma site marking was changed and the new pattern improved the rate of preoperative stoma site marking,and didn′t affect the accuracy of preoperative stoma site marking.Meanwhile,we also improved the nurses′level of preoperative stoma site marking in our department.

Objective:To investigate the correlation of atrophy and intestinal metaplasia (IM) stage with gastric cancer and to optimize biopsy strategy.Methods:Data of patients who underwent endoscopy and five-point biopsy at Shandong Provincial Hospital between November 2020 and October 2022 were collected. The baseline characteristics of gastric cancer and non-gastric cancer patients, as well as the occurrence and severity of atrophy and IM in different areas were compared. Logistic regression analysis was used to evaluate the correlation of operative link for gastritis assessment (OLGA) and operative link for gastric intestinal metaplasia assessment (OLGIM) staging with gastric cancer. The Kendall tau correlation coefficient was used to compare the consistency of different biopsy strategies (two-point, three-point, and four-point) with the standard five-point biopsy in OLGA and OLGIM staging. Receiver operating characteristic (ROC) curve analysis was further performed to compare the diagnostic performance of different biopsy strategies in identifying the OLGA and OLGIM Ⅲ-Ⅳ stage.Results:A total of 122 patients were included in the analysis, with age of 61.0±10.0 years. Multivariate analysis showed that OLGA staging was not associated with gastric cancer ( P=0.788), while OLGIM Ⅲ-Ⅳ staging was significantly correlated with gastric cancer ( P=0.006, OR=3.39, 95% CI: 1.41-8.17). The occurrence of atrophy and IM were higher in lesser curvature of the antrum [56.6% (69/122) and 66.4% (81/122)] and incisura angularis [57.4% (70/122) and 52.5% (64/122)], with higher severity, while lower in greater curvature of the corpus [2.5% (3/122) and 5.7% (7/122)], with lower severity. The consistency of four-point and three-point biopsies with standard five-point biopsy in OLGA and OLGIM staging was high. The consistency of three-point biopsy in incisura angularis, lesser curvature of the antrum and corpus was exceptionally high among them, with correlation coefficients of 0.969 and 0.987, respectively. Conclusion:OLGIM Ⅲ-Ⅳ stages increase the risk of gastric cancer. Three-point biopsy in incisura angularis, lesser curvature of the antrum and corpus are recommended for the screening and monitoring of atrophy or IM.
