Objective To explore the clinical value of resection of small gastrointestinal stromal tumor(GIST) with transparent cap assisted band ligation. Methods The clinical data of 151 patients who underwent ligation of small GIST assisted with transparent cap in our hospital from February 2017 to February 2020 were retrospectively analyzed, and the complete resection rate, recurrence rate, and complication rate, operation time, hospitalization days and other indicators were analyzed. Results Among the 151 patients with small GIST, 91 cases were located in the fundus of the stomach, 53 cases were in the stomach body, and 7 cases were in the antrum of the stomach. All the lesions were completely resected with the aid of transparent cap. Among lesions of 150 cases, the envelopes were intact and no residue was seen by naked eyes and pathology examination, and 1 case was completely resected after 2 ligations. There were 3 cases of active bleeding, no delayed bleeding, and 105 cases of iatrogenic perforation during the operation. The maximum diameter of the perforation was about 1 cm. There were 3 cases of pneumothorax and mediastinal emphysema, 3 cases of localized peritonitis, and 4 cases of fever. After hemostasis, repair and symptomatic treatment under endoscopy, no case was transferred to surgical departmat during or after operation; the average operation time was (28.3±7.6) minutes, and the average hospital stay was (4.3±1.9) days. Pathological results showed there were 132 cases of very low-risk gastrointestinal stromal tumors and 19 cases of low-risk gastrointestinal stromal tumors. There was no sign of recurrence in the gastroscope during the follow-up. Conclusion The transparent cap assisted ligation resection of small GIST was simple, safe and effective, and had the value of clinical promotion.

目的 探讨无痛镇静在胃镜下上消化道异物取出术中的应用价值。方法 回顾分析2017年5月1日—2020年5月1日在东莞东华医院消化内镜中心接受内镜下上消化道异物取出术患者,对其临床资料进行分析,总结比较在无痛镇静下和普通胃镜下上消化道异物取出术两组患者的诊疗效果。结果 共357例患者,行胃镜下异物取出术共372次,其中无痛镇静组99例,普通组273例,其中15例患者在普通胃镜下异物取出术失败改为无痛镇静下胃镜取出术成功取出,最终10人异物未取出转外科或上级医院;在无痛镇静下行胃镜上消化道异物取出术比普通胃镜下异物取出术成功率高(P＜0.05),黏膜损伤、出血、穿孔等并发症少(P＜0.05),人均费用低(P＜0.05);无痛镇静后患者血氧饱和度、血压下降(P＜0.05),心率升高(P＜0.05),其中老年人影响明显(P＜0.05),但不影响患者内镜操作,氟马西尼催醒后心率、血氧饱和度、血压恢复正常(P＞0.05)。结论 在无痛镇静下行胃镜上消化道异物取术安全、有效、成功率高、医疗费用少,患者易于接受的好方法,值得推广。

Objective To explore the application value of painless gastroscope in the removal of foreign body in upper gastrointestinal tract. Methods The study involved patients who visited at the department of endoscopy center at Hospital (Dongguan, China). Retrospective analysis of patients undergoing endoscopic removal of foreign bodies in the upper gastrointestinal tract from May 1, 2017 to May 1, 2020. We analyzed the patients' clinical data and compared the diagnosis and treatment effect between the painless gastroscope group and normal gastroscopy group. Results A total of 357 patients were included, 372 times of removal of foreign body under gastroscope were conducted. A total of 99 cases in painless gastroscope group were treated by painless gastroscope with painless sedation, 273 cases in normal gastroscopy group were treated by normal gastroscopy, among them, 15 cases were failed to removal the foreign body treated by normal gastroscopy, and turned into the painless sedation gastroscopy. Finally, 10 patients with foreign bodies were not removed and transferred to surgical department or higher level hospitals. In the treatment of endoscopic foreign body removal, the success rate of painless gastroscope group was higher (P<0.05), the complication incidence of mucosal injury, bleeding and perforation and cost per capita were lower than that of normal gastroscopy(P<0.05). Following painless sedation, the blood oxygen saturation, blood pressure dropped (P<0.05) and heart rate increased (P<0.05), the effect of the sedatives on the elderly was the most obvious (P<0.05), but it did not affect the patient's endoscopic operation, and the heart rate, blood oxygen saturation and blood pressure (P>0.05) after awakening. Conclusion Painless gastroscope in the removal of foreign body in upper gastrointestinal tract is safe, effective high success rate, less medical cost, and easy for patients to accept, it should be widely applied.

目的 探讨血清胃蛋白酶原在胃癌筛查中的价值。方法 用ELISA方法对1102名患者血清PG水平进行检测,并行内镜病理组织学检查,采用ROC曲线确定PG筛查胃癌的最佳界定值。结果 与对照组、萎缩性胃炎组、胃良性溃疡组相比,早期胃癌组、进展期胃癌组PGI、PGR下降(P＜0.05),进展期胃癌组PGI、PGR较早期胃癌组下降(P＜0.05)。与对照组相比,早期胃癌组、进展期胃癌组、胃良性溃疡组PGII升高(P＜0.05)。PGI及PGR在ROC曲线下面积为0.920和0.831,对胃癌的诊断价值较高。PGI≤71.50 μg/L或PGR≤4.50作为筛查标准时,对胃癌高危人群筛查的灵敏度为83.33%,特异度为82.25%。结论 血清PGI、PGR在不同胃部病变中的表达水平不一致,对胃癌的早期筛查和早期诊断具有重要价值。PGI≤71.50 μg/L或PGR≤4.50是东莞地区筛查胃癌较合适的界定值。

Objective To investigate the value of serum pepsinogen PG detection for screening of gastric cancer. Methods PG was detected by ELISA of 1102 people, gastrointestinal endoscopy and biopsy pathology were also carried on. Using ROC curve to establish the PG screening standard, and verified its' value at high risk population of gastric cancer. Results Compared with control group, atrophic gastritis group and benign gastric ulcer group, serum PGI and PGR in early gastric cancer group and advanced gastric cancer group decreased significantly(P＜0.05). Serum PGI and PGR in advanced gastric cancer group were lower than early gastric cancer group(P＜0.05). Serum PGII in early gastric cancer group, advanced gastric cancer group and benign gastric ulcer group were higher than control group(P＜0.05). The area under ROC curve of PGI and PGII was 0.920 and 0.831 respectively, both of them showed high value for the diagnosis of gastric cancer. Took PGI≤71.50μg/L or PGR≤4.50 as the diagnosis criteria, the sensitivity was 83.33% and specificity was 82.25% at high risk population of gastric cancer. Conclusion Serum PGI and PGR were inconsistent in different gastric disease, which showed high sensitivity and specificity in the screening of gastric cancer,and have important value in early screening and early diagnosis of gastric cancer. PGI≤71.50μg/L or PGR≤4.50 were established as the appropriate standard for PG screening.
