ABSTRACT
Objective:To investigate the clinical value of esophageal-jejunal OrVil TM anas-tomosis and Overlap anastomosis in laparoscopic radical total gastrectomy of adenocarcinoma of esophagogastric junction (AEG). Methods:The retrospective cohort study was conducted. The clinicopathological data of 112 patients with AEG who were admitted to the First Hospital of Jilin University from July 2017 to August 2022 were collected. There were 87 males and 25 females, aged (64±8)years. All 112 patients underwent laparoscopic total gastrectomy and D 2 lymphadenectomy, in which 61 cases with esophageal-jejunal OrVil TM anastomosis were divided into the OrVil TM group, 51 cases with esophageal-jejunal Overlap anastomosis were divided into the Overlap group. Observa-tion indicators: (1) surgical situations; (2) postoperative complications; (3) influencing factors for patients undergoing esophageal-jejunal OrVil TM anastomosis. Measurement data with normal distri-bution were represented as Mean± SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was conducted using the non-parameter test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Logistic regression model was used for multivariate analysis. Results:(1) Surgical situations. The esophageal invasion length and tumor diameter was 1.0(0.7,2.0)cm and (6.3±2.7)cm in patients of the OrVil TM group, versus 0.2(0.1,0.5)cm and (4.7±2.2)cm, respectively, in patients of the Overlap group, showing significant differences in the above indicators between the two groups ( Z=?6.14, t=3.26, P<0.05). (2) Postoperative complications. Cases with complications ≥Ⅲa grade of Clavien-Dindo classification, cases with respiratory system complications, cases with hydrothorax were 13, 17, 13 in the OrVil TM group, versus 4, 5, 4 in the Overlap group, showing significant differences in the above indicators between the two groups ( χ2=3.91, 5.74, 3.91, P<0.05). Cases underwent readmission within postoperative 30 days were 3 and 1 in the OrVil TM group and the Overlap group, respectively, and all patients recovered after symptomatic treatment. There were 2 cases died after operation in the OrVil TM group and none of patients died after operation in the Overlap group. (3) Influencing factors for patients undergoing esophageal-jejunal OrVil TM anastomosis. Results of multivariate analysis showed that esophageal invasion length was an independent factor influencing for patients undergoing esophageal-jejunal OrVil TM anastomosis ( odds ratio=8.25, 95% confidence interval as 3.41?19.96, P<0.05). Conclusions:Compared with esophageal-jejunal Overlap anastomosis, choosing the esophageal-jejunal Orvil TM anastomosis during laparoscopic radical total gastrectomy can take benefit to the proximal margin of patients with AEG. However, the ratios of complications ≥ Ⅲa grade of Clavien-Dindo classification, respiratory system complications and hydrothorax associated to OrVil TM anastomosis are relatively increased. Esophageal invasion length is an independent influencing factor for patients undergoing esophageal-jejunal OrVil TM anastomosis.
ABSTRACT
Objective:To investigate the influencing factors associated with lesion residual after minimally invasive rotary mastectomy for breast masses and to construct a predictive model using columnar plots.Methods:Two hundred and twenty-eight patients with Breast lumps in Linyi People’s Hospital from Jun. 2018 to Jun. 2020 were selected as study subjects, all of whom underwent minimally invasive rotational resection, and the influencing factors of postoperative lesion residual were analyzed using univariate and multifactorial analysis, and a column line graph risk warning model was constructed and given for evaluation and validation.Results:228 patients were followed up for 6 months after surgery, 3 cases were lost, 225 cases completed postoperative follow-up, among which 185 cases (82.22%) had successfully resected lesions; 40 cases (17.78%) had residual lesions. Univariate, logistic regression analysis showed that tumor diameter ( t=15.52, P<0.001) , lesion morphology ( t=15.52, P<0.001) , lesion boundary ( χ2=7.71, P=0.006) , ultrasound guidance ( χ2=12.69, P<0.001) , and minimally invasive spinotomy system ( χ2=10.64, P=0.001) were the factors influencing lesion residual after minimally invasive spinotomy of breast masses. Based on the above factors to construct a column line graph model of lesion residual after minimally invasive rotational mastectomy for breast lumps, the area under the working characteristic curve (ROC) for model subjects was 0.974 (95% CI: 0.954-0.994) , indicating that the calibration curve basically matched the actual curve; external validation of the model showed that the area under the obtained ROC was 0.962 (95% CI: 0.933-0.991) , indicating that the model has a high degree of calibration. Conclusion:Tumor diameter, lesion morphology, lesion boundary, ultrasound guidance, and minimally invasive spinotomy system are the influencing factors of lesion residual after minimally invasive spinotomy for Breast lumps, and the column line graph model prediction of lesion residual occurring after surgery constructed based on the above factors has good confidence.
