Objective To study the diagnosis and treatment in patients of esophagus carcinoma and esophagogastric junction carcinoma after operation with paralysis gastroparesis syndrome (PGS).Methods From March 1996 to December 2013 in the Affiliated Hospital of Putian University,the clinical data of PGS in 42 patients with esophagus carcinoma and esophagogastric junction carcinoma after operation were selected, and retrospectively analyzed.Results All the patients were presented with gastric retention, no obvious abdominal pain,and anal exhaust has been restored.Enteron radiography shows anastomosis and pylorus were unobstructed and gastric motility was weaken or disappear.All patients were treated with gastrointestinal decompression, nutritional support, maintaining water electrolyte metabolism balance, promoting gastrointestinal peristalsis and reducing stomach wall edema.The stomach function recovery of 40 cases was within 10-15 days, respectively.Two patients cured by pyloroplasty when they were not improved by conservative treatment for 2 months.And the stomach function recovery were within 28 days and 35 days.Conclusion Gastroparesis syndrome is a functional disease,the cure rate is high, the treatment of first choice was conservative treatment, however, for the intractable gastroparesis, pyloroplasty maybe another good choice.

Objective To study the clinical application of mediastinal elastic drainage-tube for patients with anastomotic leak after esophagus carcinoma or esophagogastric junction carcinoma surgery.Methods Two hundred and eighty-two cases esophagus carcinoma or esophagogastric junction carcinoma patients were randomly divided into 2 groups.The control group(n=140) were indwelled thoracic drainage tube after operation.However,the experimental group(n=142) were indwelled thoracic drainage tube and mediastinal elastic drainage-tube after operation.The incidence of the esophagogastrostomy fistula,diagnosis time of anastomotic leakage,maximum temperature,time of continuous ferer,total white blood cell count,cardiopulmonary complications,postoperative hospital stay,hospitalization expenses were observed and analyzed.Results (1)The incidence of the esophagogastrostomy fistula in the experimental group and the control group was 9.8%(14/142) and 12.1%(17/140),and there was no significant difference between the two groups(χ2=0.376,P>0.05).The diagnosis time of anastomotic leakage,maximum temperature,time of continuous ferer and total white blood cell count of the experimental group and the control group was (6.4±0.6) d and (10.6±0.6) d,(38.1±0.1)℃ and (39.0±0.2)℃,(72.2±2.8) h and (102.6±3.3) h,(12.6±0.7)×109/L and (19.7±0.6)×109/L after operation,there was significant difference between the two groups(t=2.708,1.662,3.164,1.837,P<0.05).The incidence of pulmonary complication,cordis complication of the experimental group and the control group was 19.7%(28/142) and 32.1%(45/140),18.3%(26/142) and 40.7%(57/140) after operation,there was significant difference between the two groups (χ2=5.077,6.606,P<0.05).The postoperative hospital stay,hospitalization expenses of the experimental group and the control group was (28.1±4.2) d and (45.6±3.9) d,￥(6 8174.7±3206.5) and￥(8 4774.8±4007.3) after operation,there was significant difference between the two groups(t=2.001,1.709,P<0.05).Conclusion The mediastinal elastic drainage-tube for patients with anastomotic leak after esophagus carcinoma or esophagogastric junction carcinoma surgery can not reduce the incidence of the esophagogastrostomy fistula,but which is conducive to the early diagnosis and timely treatment of anastomotic leakage.Meanwhile it can reduce the incidence rate of cardiac and pulmonary complications,shorten the length of stay in hospital,reduce the total cost of hospitalization.

Objective To study the clinical significance of the novel tumor marker Cytokerantin?19?fragment( CYFRA 21?1) of peripheral blood in patients with esophageal cancer. Methods The CYFRA 21?1 level in peripheral blood of 72 patients with benign tumor of esophagus or reflux esophagitis and 60 patients with esophageal cancer was examined before and 7 days after operation by enzyme?linked immuno sorbent assay ( ELISA) . At the same time, patients with esophageal cancer were followed up for 3 years, and the level of CYFRA21?1 was examined. Results (1)Before the operation,the level of CYFRA 21?1 was 0-3. 30 μg/L in 51. 67%( 31/60 ) of the patients with esophageal cancer, higher than that of the control group ( 16. 67%(12/72),χ2=3. 88,P<0. 05). (2)Before the operation,the level of CYFRA21?1 in patients with esophageal cancer,stage Ⅰ,Ⅱ and stage Ⅲ,Ⅳ were (3. 27±0. 33) μg/L and (4. 88±1. 21) μg/L,and of the control group was (2. 24±1. 17) μg/L. The levle of CYFRA21?1 in patients with esophageal cancer,stage Ⅰ,Ⅱ andⅢ,Ⅳ were significantly higher than that of the control group( t=2. 37,2. 00,P<0. 05) . ( 3) On the 7th day after operation,the level of CYFRA21?1 was (2. 26±1. 16) μg/L,and the difference was not significant compared with the control group(t=0. 95,P>0. 05). The level of CYFRA21?1 with the palliative resection of esophageal cancer was (3. 31±0. 66) μg/L,and the difference was significant compared with the control group(t=4. 33,P<0. 05) . ( 4 ) After 3 years of follow?up, the factors affecting the survival rate of esophageal cancer were as following:the pathologic stages of tumor(OR 4. 423,95%CI 1. 943-4. 972,P<0. 05),types of operation(OR 0. 023,95%CI 0. 012-0. 036,P<0. 05),the level of CYFRA21?1 before operation(OR 6. 798,95%CI 4. 328-8. 105,P<0. 05),and the decreased level of CYFRA21?1 after operation(OR 0. 117,95%CI 0. 074-0. 202,P<0. 05) . ( 5) During the follow?up period,the level of CYFRA21?1 in patients with local recurrence and distant metastasis of esophageal carcinoma was (7. 97±0. 44) μg/L,significantly more than that of the control group(t=5. 11,P <0. 05) . Conclusion CYFRA21?1 is a useful tumor marker in the positive rate of preoperative diagnosis of esophageal cancer, postoperative monitoring of recurrence, distant metastasis and prediction of prognosis.

Objective:To investigate the effects of supplemental parenteral nutrition on postoperative nutritional status, immune function and inflammatory response in patients with esophageal cancer after operation.Methods:A prospective study was performed on 72 patients with esophageal cancer who visited the Department of Thoracic and Cardiovascular Surgery of the Affiliated Hospital of Putian University from June 2018 to June 2020. According to the random table of new drug data statistics and processing software, they were randomly divided into experimental group (supplementary parenteral nutrition group) and the control group (complete enteral nutrition group), with 36 cases in each group. The experimental group was given enteral nutrition (EN) from the first day after operation, and EN and parenteral nutrition (PN) was given on the 4th to 8th day after operation. In the control group, EN was started on the first day after operation. The changes of nutritional status, immune function and inflammatory indexes in the perioperative period were compared between the two groups. Mann-Whitney U test was used for measurement data that did not meet the normality standard, and t test was used to compare measurement data that met the normality standard between groups. Nutrition indicators, inflammatory indicators and immune indicators used repeated measures analysis of variance. For enumeration data, Mann-Whitney U test was used for hierarchical classification data, and χ 2 test was used for unordered multi-classification data. Results:On the 1st day after operation, the prealbumin concentration ((95.34±37.93) mg/L and (81.60±37.68) mg/L) in the experimental group and the control group was significantly higher than that before the operation ((144.86±46.79) mg/L and (130.39±50.91) mg/L), and the differences were statistically significant (all P<0.001), and there was no significant difference between the two groups (all P>0.05).
