RESUMO
Objective:To evaluate endoscopic retrograde appendicitis therapy in treatment of children with acute uncomplicated appendicitis.Methods:Sixty children patients were admitted at the Affiliated Hospital of Zhengzhou University from Oct 2019 to Jun 2021 and were divided into ERAT group ( n=30) and LA group ( n=30). Results:All operations were successfully performed . ERAT children started oral feeding earlier [(6.8±2.0) h vs. (12.3±2.0) h, t=-10.636, P<0.001], postoperative hospital stay was shorter [(3.2±1.3) d vs. (5.0±1.3) d, t=-5.360, P<0.001]. After 14 months follow up, the recurrence rate in the ERAT group was 6%. The complication rate of LA was 10%. Conclusion:ERAT is a safe and effective therapy in treating children with acute uncomplicated appendicitis with low,acceptable recurrence rate.
RESUMO
Objective:To study the safety and effectiveness of endoscopic full-thickness resection(EFR) in the treatment of large gastric stromal tumors with diameter of 5-7 cm.Methods:Data of 36 patients with large gastric stromal tumors (5-7 cm) who received EFR or surgery (including laparoscopic and open surgery) in the First Affiliated Hospital of Zhengzhou University and confirmed by postoperative histopathology from January 2017 to October 2018 were retrospectively analyzed. Patients were divided into endoscopic group (9 cases) and surgical group (27 cases) according to different resection methods. The perioperative indicators and the total incidence of complications in the two groups were compared.Results:In terms of perioperative indicators, the median operation time of the endoscopic group was significantly longer than that of the surgical group (4.0 hours VS 2.0 hours, P<0.01), and the postoperative fasting time (4.55±0.88 days VS 6.22±2.24 days, t=-2.15, P=0.03) and hospital stay (6.88±1.26 days VS 10.03±2.90 days, t=-3.13, P<0.01) were significantly shorter than those of the surgical group. The median visual analogue scores (VAS) of abdominal pain of the endoscopic group on the first postoperative day (3 VS 6, P<0.01)and the third postoperative day (1 VS 3, P<0.01) were significantly lower than those of the surgical group. The hospitalization cost was significantly less than that of the surgical group (55±14.7 thousand yuan VS 73±24.3 thousand yuan, t=-2.11, P=0.04). In term of the total incidence of complications, the endoscopic group was 11.1% (1/9), which was higher than that of the surgical group [7.4% (2/27)], but there was no statistically significant difference( P=1.00). Conclusion:EFR is safe and effective in the treatment of large gastric stromal tumors (5-7 cm), and has the advantages of less invasiveness, rapid postoperative recovery, and lower hospitalization cost. But how to shorten the operation time is an urgent problem to be solved.
RESUMO
From June 2017 to September 2019, 5 patients who were diagnosed as having benign severe pyloric stenosis underwent fully covered stent placement using a new stenting method at the First Affiliated Hospital of Zhengzhou University. Five patients were performed successfully without serious complications. Postoperative barium meal radiograph revealed that the stents were in good location and the acontrast agent passed smoothly. The liquid diet was commenced 1-3 days after surgery. No vomiting, abdominal pain and diarrhea occurred. During the follow-up, all the patients had improved weight and nutritional status. Four patients underwent stent removal 3-4 months postoperatively. One patient was found that the stent had migrated to stomach 3 months after discharge. After removing the stent, balloon dilation and mucosal resection was performed for the mild pyloric stenosis. All 5 patients had an additional follow-up of 3 months, and no symptoms and restenosis occured. These preliminary results showed that the new stenting method of fully covered stent placement is feasible, safe and effective in the treatment of benign pyloric stenosis.
RESUMO
Objective To compare the difference between modified peroral endoscopic myotomy (Liu?POEM) and conventional POEM for achalasia. Methods Thirty achalasia patients treated with Liu?POEM and 30 with conventional POEM were enrolled. A retrospective study was performed to compare the conventional POEM and Liu?POEM procedures by evaluating total operation time, postoperative complications and symptoms( Eckardt score) . Results The average total operation time of Liu?POEM was 27?13 ±11?42 min and the average myotomy time was 13?20±5?09 min. There was no pneumomediastinum, subcutaneous emphysema or fever. The average total operation time of conventional POEM was 51?22 ± 25?63 min. The average myotomy time was 11?18±7?61 min. There were three cases(10%) of subcutaneous emphysema but recovered after two days without any special treatment. One patient who underwent conventional POEM had fever( the highest temperature was 37?6℃) and his temperature subsided to normal after physical cooling in one day. Postoperative Eckardt scores of patients were all less than 3. After postoperative follow?up of 3 to 12 months, no complications occurred in any patient. Conclusion Liu?POEM is a modified approach to treat achalasia, advantageous over conventional POEM in more simplified operation procedure, shorter operation time and less invasiveness.
