内镜下氩离子凝固术治疗食管上段胃粘膜异位的护理 总被引:1,自引:0,他引:1
食管上段胃粘膜异位(heterotopic gastric mucosa in upper esophagus,HGMUE)是胚胎发育时期鳞状上皮不完全取代柱状上皮形成的先天性残余病变。患者多无临床症状,但也可以出现胸骨后烧灼感、吞咽困难或疼痛、咽部不适等症状,可导致溃疡、穿孔、瘘管等并发症。2005年1月至2008年8月,我科对25例内科治疗效果差的食管上段胃粘膜异位患者进行内镜下氩离子凝固术(argon plasma coagulation,APC)治疗,取得了良好效果,现将护理体会报告如下。 相似文献

PurposeArgon plasma coagulation (APC) is a standard modality for the treatment of gastrointestinal bleeding. However, there are no metrics to assess technical proficiency. We aimed to determine if a Quick APC Training Test (QAPCTT) can improve performance and assess proficiency with this modality.Materials and methodsEndoscopy trainees at various levels of training were asked to perform the QAPCTT with an in vivo model before and after an APC curriculum with didactic lectures and additional hands-on experience. As trainees performed the test, endoscopic supervisors recorded the time required to complete each task as well as the number of inadvertent mucosal touchdowns. Each partipant was assigned a technical proficiency score by supervising endoscopists.ResultsFourteen adult gastroenterology fellows participated in the course. 100% of fellows were comfortable with generator settings and APC equipment after the course compared to only 21% (p < 0.001) on the pre-test questionnaire. Those deemed technically proficient on the post-course QAPCTT required significantly less time for the task of making a square (100 s vs. 215 s; p = 0.006) and had significantly fewer inadvertent mucosal touchdowns (5 vs. 19; p = 0.0017).ConclusionsDedicated APC training is required to achieve competence with this modality. A structured curriculum improves knowledge about the technique and hands-on training is important for achieving technical proficiency. The QAPCTT appears improve APC technique and may readily identify trainees in need of additional APC experience to gain proficiency. 相似文献

The pepsinogen A (PGA) isozymogens in the gastric mucosa and Barrett epithelium of a female patient with Barrett esophagus were studied on different occasions during a 3-year period by electrophoretic analysis of in vivo steady-state pepsinogen in biopsies by activity staining in combination with variant specific monoclonal antibodies and of de novo synthesized pepsinogen by autoradiography. In Barrett epithelium only one (Pg3) or two (Pg3 and Pg5) primary PGA gene products were detected, whereas in gastric mucosal biopsies three (Pg3, Pg4 and Pg5) primary gene products were demonstrated on all occasions. These differences strongly suggest differential expression/activation of individual gene numbers in the PGA gene cluster in Barrett esophagus and are in line with the preneoplastic nature of this condition. The mechanism behind this deregulation is currently under investigation by cell biology and molecular genetic techniques. 相似文献

Although debatable, role of cytology in diagnosing Barrett's esophagus has been stressed by some authors. Our brief report analyses the role of brush cytology (BC) in its diagnosis. Eight patients who presented with upper gastrointestinal (GI) manifestations and subsequently diagnosed to have Barrett's esophagus with or without adenocarcinoma on brush cytology (BC) or, endoscopic biopsy (EB) or, a combination of both the techniques were included in the study. In all the cases routine cytologic smears and histologic sections with relevant special stains (when essential) were studied. On cytology, the diagnosis of "Barrett's esophagus" was made when the esophageal brushings obtained from a region beyond 3 cm from the gastroesophageal junction showed closely intermingled clusters of squamous and columnar cells, or when there was evidence of intestinal metaplasia. Adenocarcinoma in Barrett's esophagus was diagnosed by the usual criteria for malignancy with features of adenocarcinoma. Cytologic diagnoses were correlated with the histologic diagnoses. Of the eight cases, seven had histopathologic correlation of which six had evidence of BE on BC; four had cytohistologic concordance, of which three cases revealed adenocarcinoma arising in BE. Two endoscopic biopsies were nonrepresentative. In one case, cytology missed Barrett's esophagus. For two cases in which cytology detected Barrett's mucosa, biopsies were nonrepresentative. Our study showed brush cytology (BC) to be a fairly reliable test for detecting Barrett's esophagus. Owing to its inherent advantage of sampling a wider and circumferential area, a technically well performed brushing procedure is likely to be more representative and superior than multiple endoscopic biopsies. 相似文献

Carboxylate and sulfate groups were introduced at the surface of poly(ethylene) (PE) samples. This was accomplished by coating and immobilizing sodium 10-undecenoate (C11(:)) and 10-undecene sulfate (S11(:)) on the polymer by means of an argon plasma treatment. The composition of the coated surfactant layer was proportional to the composition of the coating solution. The thickness of the surfactant layer on the surface of PE samples, which were precoated from an aqueous solution with a total surfactant concentration of 0.30 M, was about 55 A°. The presence of carboxylate and sulfate groups after plasma treatment of the precoated surfaces was confirmed by X-ray photoelectron spectroscopy (XPS). About 20% of the initial amount of functional groups of the coated surfactants was retained at the PE surface. The ratio of carboxylate/ sulfate groups at the plasma treated surfaces was dependent on the composition of the precoated surfaces. The minimum surface density of these groups on the resulting samples was about one group per 40 A°2. 相似文献

Barrett's oesophagus is a major risk factor for developing oesophageal adenocarcinoma. Ablation by argon plasma coagulation (APC) and photodynamic therapy (PDT) is currently under investigation for the removal of metaplastic and dysplastic Barrett's oesophagus. This study examined the effect of ablative therapy on Barrett's oesophagus at cell-cycle and genetic levels. The premalignant potential of residual or recurring Barrett's oesophagus was assessed by p53 immunohistochemistry, Ki67-related proliferative capacity, and DNA ploidy status (ie an abnormal chromosome 1 number) as measured by interphase in situ hybridization. Twenty-nine patients with Barrett's oesophagus (23 male and 6 female, mean age 58 years, mean length of Barrett's oesophagus 4 cm) were treated with APC or PDT. Intestinal metaplasia without dysplasia was present in 16 patients, low-grade dysplasia in five, and high-grade dysplasia in eight patients. Biopsy samples were obtained at regular intervals (mean follow-up 20 months, range 6-36 months). One month after the first ablation, Barrett's oesophagus was no longer identified, either endoscopically or histologically, in nine patients (32%). At this time point, significant down-grading was achieved for abnormal chromosome 1 numbers (p = 0.020) and Ki67-defined proliferation (p = 0.002). Patients with residual Barrett's oesophagus were additionally treated with APC, resulting in the elimination of Barrett's oesophagus in 76% of all patients. However, at the last follow-up endoscopy, metaplasia without dysplasia was still present in five patients, and low- and high-grade dysplasia were each present in one patient. An abnormal chromosome 1 number and p53 protein overexpression were detected only in the high-grade dysplastic lesion, but increased proliferation was still present in the majority of these persisting cases. Although endoscopic removal of Barrett's oesophagus by ablative therapies is possible in the majority of patients, histologically complete elimination cannot be achieved in all cases. Persistent Barrett's oesophagus may still harbour molecular aberrations and must therefore be considered still to be at risk of progression to adenocarcinoma. 相似文献

We report a rarely documented case of adenocarcinoma of esophagus with signet-ring cell features arising in a Barrett's esophagus. This was diagnosed by employing combined endosonography and fine-needle aspiration cytology. The patient had progressive dysphagia and a poorly circumscribed mass involving the distal esophagus and gastroesophageal junction. An incisional biopsy was performed which showed Barrett's esophagus with highly atypical glands suspicious for adenocarcinoma. Following that, an ultrasound-guided endoscopic fine-needle aspiration revealed a cellular specimen with multiple groups and singly dispersed atypical glandular cells with a predominance of signet-ring features. These findings represented an adenocarcinoma with signet-ring cell features arising in Barrett's esophagus. Diagn. Cytopathol. 1998;19:51–54. © 1998 Wiley-Liss, Inc. 相似文献
