ObjectiveTo assess the efficacy of lymphadenectomy in different regions for esophageal squamous cell carcinomas located differently according to the lymph node grouping by Chinese expert consensus. MethodsThe medical records of 1 061 patients (886 males and 175 females with a median age of 60 (54, 65) years with esophageal cancer from March 2011 to December 2017 in our hospital were retrospectively analyzed. According to the pathological report, the lymph nodes were regrouped according to the Chinese lymph nodes grouping standard of esophageal cancer. The metastasis rate of each group of lymph nodes, the 5-year survival rate of metastatic patients and efficacy index (EI) were calculated. ResultsThe upper thoracic esophageal cancer mainly metastasized to the lymph nodes of C201-203 groups. The middle and lower thoracic tumors mainly metastasized to the lymph nodes of C205-207 groups. The lower thoracic tumor had a higher rate of metastasis to the abdominal lymph nodes. According to the metastasis rate, the mediastinal lymph nodes were divided into three regions: an upper mediastinum (C201-204), a middle mediastinum (C205-206), and a lower mediastinum (C207-209). The EIs of lymph nodes of C201-203 and C205-207 groups were higher. For patients with C201-207 groups metastasis, the 5-year survival rates ranged from 13.39% to 21.60%. For patients with positive lymph nodes in each region, tumors at different primary locations had no statistical difference in long-term survival (P>0.05). Patients with lymph nodes of C205 group in the upper thoracic tumors had lower EI and those in the middle and lower thoracic tumors had higher EIs. ConclusionThe effect of lymph node dissection in each area varies with the location of the tumor. No matter where the tumor is, it is necessary to dissect the upper mediastinal lymph nodes, especially the lymph nodes adjacent to the left and right recurrent laryngeal nerves. Group C205 should be classified into the lower mediastinal lymph nodes.

In perioperation period, the dynamic changes of solubla interleulcin-2 receptor (sIL-2R) in serum were determined by ELISA in 60 patients with gastric cancer (GC), and then was compared with those of 30 normal individuals and 40 selective patients who necieved common abdominal surgery. Results: At the day before and ten days after operation, the sIL-2R of patients with GC was higher than that of normal individual. But twenty days after operation, the sIL-2R reduced to as normal level. Conclusion: As a immunodepressive index, the sIL-2R of patients with GC was increased obviously, and after radical gastrectomy, it decreased gradually. So by determining sIL-2R, we can evaluate the immunologic function of patientswith GC.
ObjectiveTo assess the outcomes of laparoscopy-assisted surgery for treatment of advanced gastric cancer.MethodsA total of 115 patients with advanced gastric cancer were included between January 2014 and December 2018 were analyzed retroprospectively, the patients were divided into two groups: open surgery group (OS group, n=63) and laparoscopy-assisted surgery group (LAS group, n=52). Baseline characteristics, intraoperative parameters and postoperative items, and long-term efficacy were compared between the two groups.ResultsThere was no significant difference in preoperative baseline data including gender, age and preoperative serum parameters between the two groups (P>0.05). Intraoperative blood loss in the LAS group was significantly less than that in the OS group (P<0.05). In addition, the first feeding time after operation and postoperative hospital stay in the LAS group were significantly shorter than the OS group (P<0.05). Furthermore, numbers of white blood cells and neutrophils in the LAS group were fewer than that in the OS group at postoperative 2 days (P<0.05); the level of serum albumin in the LAS group was higher than that OS group (P<0.05). The number of lymph nodes detected during operation in the LAS group was more than that in the OS group (P<0.05). Operative time and occurrence of postoperative complications were not statistically significant between the two groups (P>0.05). One hundred and ten of 115 patients were followed- up, the follow-up rate was 95.7%. The follow-up time ranged from 6 to 48 months, with a median follow-up time of 12.4 months. The disease-free survival time of the OS group was 12.2±6.5 months, while that of the LAS group was 13.5±7.4 months. There was no significant difference between the two groups (P>0.05).ConclusionsLaparoscopic technique in treatment of advanced gastric cancer has the minimally invasive advantage, less intraoperative blood loss, less surgical trauma, and faster postoperative recovery in comparing to the traditional open surgery. Also the lymph node dissection is superior to open surgery. The curative effect is comparable to that of open surgery.
Abstract: Objective To investigate the method of improving effect, by investigating and analyzing the possible risk factors affecting shortterm outcome after total correction of tetralogy of Fallot (TOF). Methods Data of 219 patients who received total correction of TOF were divided into two groups according to the length of postoperative stay in hospital and recovery of heart function in the near future. Group A(n=110): patients had good recovery of heart function classified as gradeⅠorⅡ（NYHA classification）, and could smoothly be discharged from the hospital within two weeks without serious complications. The left ventricular ejection fraction (LVEF) had to exceed to 0.50 during 6 months followup visit. Group B(n=109): patients had worse recovery of heart function classified as grade Ⅱ or Ⅲ, and could not be discharged within two weeks with severe complications. LVEF was less than 0.50 during 6 months followup visit. The clinical data of two groups were compared, and risk factors affecting shortterm outcome after total correction of TOF operation were analyzed by logistic regression and model selection. Results There were good recovery of heart function classified as gradeⅠorⅡ(NYHA classification）in discharge, no death, and LVEF all exceeded to 0.50 in group A; there were 8 deaths in group B (7.34 %), and recovery of heart function was worse classified as grade Ⅱ or Ⅲ, with LVEF being less than 0.50（Plt;0.01）. Amount of postoperative daily thoracic drainage, assisted respiration time, time of inotropic agent stabilizing circulation, and the average length of postoperative stay in group A were all less or short than those in group B（Plt;0.01）. But the bypass and clamping time of group B were exceeded group A. The ratio of patching astride annulus in group B was greater than that in group A, and Nakata index was less than that in group A(Plt;0.01). The results of logistic regression and model selection indicate: age at repair (OR=0.69), oxygen saturation(OR=0.98), haematocrit before operation (OR=0.94), and patching astride annulus (OR=46.86), Nakata index (OR=16.90), amount of postoperative daily thoracic drainage (OR=0.84), presence of arrhythmia(OR=0.87), and wound infection(OR=63.57) have significant effect with shortterm outcome after total correction of TOF operation. Conclusions The probable methods to improving effect of shortterm outcome after total correction of TOF are an earlier age at repair, decreasing haematocrit, rising oxygen saturation before surgery, performing a palliative operation facilitating development of arteriae pulmonalis in earlier time, improving the surgical technique, and strengthening the perioperative care.
ObjectiveTo analyze the risk factors affecting delayed gastric emptying (DGE) after laparoscopic distal gastrectomy for gastric cancer. MethodsThe gastric cancer patients who underwent laparoscopic distal gastrectomy in the Jiaozuo People’s Hospital from January 1, 2013 to December 31, 2022 were retrospectively collected. The occurrence of DGE was recorded. Meanwhile, the multivariate binary logistic regression analysis was performed to screen the risk factors affecting the DGE. ResultsA total of 350 gastric cancer patients underwent laparoscopic distal gastrectomy and met the inclusion and exclusion criteria of this study were included, 17 (4.9%) of whom developed DGE. The multivariate binary logistic regression analysis results showed that the preoperative gastric outflow tract obstruction (OR=8.582, P=0.009), intraoperative jejunal nutrition tube indwelling (OR=14.317, P=0.010), more peritoneal drainage tube placement (OR=5.455, P=0.006), and intraoperative blood loss ≥140 mL (OR=4.912, P=0.018) increased the risk of DGE. ConclusionAccording to the results of this study, when patients undergoing laparoscopic distal radical gastrectomy for gastric cancer accompanied by preoperative gastric outflow tract obstruction, intraoperative jejunal nutrition tube indwelling, more peritoneal drainage tube placement, and more intraoperative blood loss, it should be paid more attention to prevention DGE, and early detection and treatment, so as to improve the prognosis of patients.
