ABSTRACT
Objective:To study the safety and efficacy of hiatal hernia-endoscopic submucosal dissection (HH-ESD) for the treatment of giant hiatal hernia (>3 cm in length) complicated with refractory gastroesophageal reflux disease (GERD).Methods:Patients with giant hiatal hernia complicated with refractory GERD who voluntarily received HH-ESD at the Digestive Endoscopy Center of the Affiliated People's Hospital of Inner Mongolia Medical University from April 2018 to March 2020 were included in the clinical study. The completion of HH-ESD and the occurrence of complications were observed, and the changes of indicators before and after the treatment were observed, including gastroesophageal reflux disease-health related quality of life (GERD-HRQL) score, gastroesophageal reflux disease questionnaire (GERD-Q) score, endoscopy results, 24 h esophageal pH monitoring results, esophageal high-resolution manometry results and proton pump inhibitor (PPI) usage.Results:Data of 10 patients were collected during the study, with a medical history of 2-10 years. All patients successfully underwent HH-ESD treatment. No adverse events such as perforation and massive bleeding occurred during the operation, and the hospital stay was 6-12 days. Dysphagia occurred in 3 cases after the operation, which was relieved spontaneously within 3 or 6 months. The preoperative GERD-HRQL scores ranged from 19 to 29, which were reduced to 0-14 and 0-8 at 3 and 12 months after the operation, respectively. The preoperative GERD-Q score was 9-17, and the scores at 3 and 12 months after the operation were all 6-9, which were significantly lower than those before. Gastroscopy showed that esophagitis was improved in all patients, hernia sac was reduced, and Hill grade was reduced compared with that before. The preoperative DeMeester score was 30.3-247.1, and the postoperative 12-month score was 0.2-29.9, which was significantly lower than that before. The long diameter of hiatal hernia was 3.0-6.0 cm before the operation and 0-5.0 cm at 12 months after, which was smaller than that before. At 12 months of the follow-up, 7 patients had stopped PPI, and the remaining 3 had changed to intermittent oral PPI.Conclusion:Preliminary results show that HH-ESD is safe and effective for the treatment of giant hiatal hernia complicated with refractory GERD.
ABSTRACT
Objective To study the safety and efficacy of peroral endoscopic cardial constriction (PECC) for gastroesophageal reflux disease (GERD). Methods A total of 27 patients with GERD who visited the Affiliated Hospital of Inner Mongolia Medical University from August 2016 to December 2017 and met the inclusion criteria received PECC. The 24 h esophageal pH-resistance monitoring ( DeMeester ) scores, GERD health-related quality of life ( GERD-HRQL ) scores, GERD-questionnaires ( GERD-Q ) symptom scores and clinical efficacy before and after operation were compared. Results DeMeester score at 3 months ( Z=-6. 940, P=0. 001) and 6 months ( Z=-6. 307, P=0. 001) after treatment, GERD-HRQL score at 3 months ( t=11. 499, P=0. 001) and 6 months ( t=10. 959, P=0. 001) as well as GERD-Q symptom score at 3 months ( t=30. 647, P=0. 001) and 6 months ( t=27. 217, P =0. 001) after surgery significantly decreased, compared with those before. The curative rates were 81. 5％ ( 22/27) and 77. 8％(21/27) at 3 months and 6 months after operation. Conclusion PECC, a new method for the treatment of GERD with good short-term effect, safety and feasibility,can be recommended for clinical application.
ABSTRACT
Objective To explore the clinical safety of peroral endoscopic cardial constriction for gastro-esophageal reflux.Methods Clinical data of 47 patients with gastro-esophageal reflux who underwent peroral endoscopic cardial constriction in Chinese PLA General Hospital were retrospectively studied from August 2013 to August 2016.Results A total of 47 patients underwent peroral endoscopic cardial constriction successfully with no perforation or fever.Retrostemal vague pain and discomfort occurred in 7 cases,mild dysphagia occurred in 2 cases,and mild hemoptysis occurred in one patient the day after the operation.No special measures were taken and all 10 patients showed symptom remission in less than two days.As for the postoperative treatment,22 (46.8％) patients were given a liquid diet on the day of operation,39(82.9％) patients were given semi-or liquid diet on the first day after the operation,and two days later,43 (91.5％) resumed semi-or liquid diet.Only 9 cases were given antibiotics for prophylaxis for infection.Conclusion Peroral endoscopic cardial constriction is safe and effective for gastro-esophageal reflux.The hospitalizing time is short and postoperative recovery is quick.
ABSTRACT
Objective To conduct the molecular epidemiologic analysis of Staphylococcus aureus (S.aureus) in the intensive care units(ICUs) and general wards and to compare their clinical characteristics.Methods Ninety-six clinically isolated strains of S.aureus(43 strains from the emergency intensive care unit(EICU) and neurosurgical intensive care unit(NICU) and 53 strains from the general wards) collected from Sepetember 2015 to April 2016 were performed the bacterial identification and antibiotic susceptibility test.The molecular typing was performed by adopting staphylococcal protein A (spa) typing method.Results Among 96 strains of S.aureus,the detection rate of methicillin-resistant S.aureus(MRSA) was 40.6%(39/96),which among 43 strains in ICU was 62.8%(27/43) and which among 53 strains in the general words was 22.6%(12/53).The resistance rates of strains from ICUs to gentamicin,levofloxacin,clindamycin,fosfomycin and minocycline were 23.3%,48.8%,46.5%,32.6% and 32.5% respectively,while which from the general wards were 7.5%,24.5%,18.9%,2.1% and 0% respectively.The Spa typing results showed that the main types of ICUs were t002,t091 and t311.The major epidemic strain was t002(n=16,37.2%) and mainly isolated from EICUs(12 strains),26 spa types were identified among the general wards trains,mainly were t189,t377,t571,t034,t091,t127.Conclusion The detection rate of MRSA in ICUs is higher than that in the general wards,these strains have high resistant rate to routine antibacterial drugs.t002 is the major epidemic strain.The general wards have more spa types with higher genetic diversity.
ABSTRACT
Objective To evaluate the clinical value of preoperative mark with methylene blue for the submucosal tumor originating from the muscluaris propria around the cardia in submucosal tunnel.Meth-ods A total of 27 patients with cardiac tumors originating from muscularis propria diagnosed by endoscopy and endoscopic ultrasonography underwent endoscopic submucosal tunnel dissection from June 2011 to May 2014.Eighteen cases were marked by methylene blue,and 9 others were not.The operation time and the in-cidence of complications were compared between the two groups.Results All lesions were resected success-fully.The time of lesion location of non-mark group was 14.7 minutes(9-32 min),and that of mark group was 8.1 minutes(7-10 min).The incidence of subcutaneous emphysema of thorax and cervix of non-mark group was 2 /9(2 cases),and that of the mark group was 1 /18(1 case).The incidence of pneumoperitone-um of non-mark group was 1 /9(1 case),while that of the mark group was 2 /18(2 cases).There was no pneumothorax or mediastinal emphesema in all cases.Conclusion Marking with methylene blue before op-eration can shorten operation time effectively and lower incidence of complications.
ABSTRACT
<p><b>OBJECTIVE</b>To examine the feasibility and safety of gastric submucosal tunnel dissection of gastric submucosal tumors (SMTs) by double tunnel and double flex endoscope.</p><p><b>METHODS</b>Fifty patients with gastric SMTs detected by gastric endoscopy and endoscopic ultrasonography between January, 2012 and August, 2013 were enrolled in this study. Using carbon dioxide throughout the procedure, the mucous in the arc was incised along the margins of the lesion to separate the submucosa and create a tunnel. The exposed SMTs were resected completely and the mucosa was covered by endoscopic forceps followed by clipping of the incision. The complication, clinical outcomes, hospital stays and operation time were evaluated.</p><p><b>RESULTS</b>Of the 50 lesions, 50 were located in the gastric fundus, 17 in the gastric antrum and 5 in the gastric body. The lesions were completely resected in all the patients. The diameter of the resected lesions ranged from 0.5 to 2.5 cm (mean 1.1 ± 0.6 cm), and the operation lasted for 35.3 ± 16.2 min (range 23-76 min). In 5 cases (10%), perforation occurred during the operation and was closed by clipping the incision with endoclips after the lesion resection; these patients were discharged after conservative management. Intraoperative bleeding occurred in 16 cases and was successfully managed through endoscopic methods. No delayed postoperative bleeding or perforation occurred in these patients. None of the 48 patients followed up showed tumor recurrence at one year after the operation, and 2 patients were lost for follow up.</p><p><b>CONCLUSION</b>Endoscopic submucosal dissection of gastric SMTs is effective and safe using double tunnel and double flex endoscope.</p>
