METHODS Seventy EC patients undergoing ESD were enrolled in this randomized, controlled study. Patients were allocated randomly at a 1:1 ratio into two groups as follows:(1) PGA plus stent group(PGA sheet-coated stent placement was performed); and(2) Stent group(only stent placement was performed). This study was registered on http://www.chictr.org.cn(No. chictrinr-16008709). RESULTS The occurrence rate of esophageal stricture in the PGA plus stent group was 20.5%(n = 7), which was lower than that in the stent group(46.9%, n = 15)(P = 0.024). The mean value of esophageal stricture time was 59.6 ± 16.1 d and 70.7 ± 28.6 d in the PGA plus stent group and stent group(P = 0.174), respectively. Times of balloon dilatation in the PGA plus stent group were less than those in the stent group [4(2-5) vs 6(1-14), P = 0.007]. The length(P = 0.080) and diameter(P = 0.061) of esophageal strictures were numerically decreased in the PGA plus stent group, whereas no difference in location(P = 0.232) between the two groups was found. Multivariate logistic analysis suggested that PGA plus stent placement(P = 0.026) was an independent predictive factor for a lower risk of esophageal stricture, while location in the middle third(P = 0.034) and circumferential range = 1/1(P = 0.028) could independently predict a higher risk of esophageal stricture in EC patients after ESD. CONCLUSION PGA plus stent placement is more effective in preventing post-ESD esophageal stricture compared with stent placement alone in EC patients with earlystage disease.展开更多

Inclusion criteria was completed SEMS/SEPS placement. Outcomes assessed included technical success of and time required for stent placement, procedure-related complications, need for repeat intervention, hospital stay, mortality and costs.RESULTS: Forty-three patients underwent stent placement for either benign/malignant esophagealdisease during the study period. Thirty patients had SEMS(25 male, mean age 59.6 years old) and 13 patients had SEPS(10 male, mean age 61.7 years old). Placement outcome as well as complication rate(SEPS 23.1%, SEMS 25.2%) and in-hospital mortality(SEPS 7.7%, SEMS 6.7%) after placement did not differ between stent types. Migration was the most frequent complication reported occurring equally between types(SEPS 66.7%, SEMS 57.1%). SEPS was less costly than SEMS, decreasing institutional cost by $255/stent.CONCLUSION: SEPS and SEMS have similar outcomes when used for benign or malignant esophageal conditions. However, SEPS use results in decreased costs without impacting care.展开更多

It is inoperable when firstmanifested in more than 50% of cases. So, palliationis the only therapeutic option for the advanced diseaseto relieve dysphagia and its consequences in weakenedpatients with an estimated mean survival under 6 mo.This article has tried to identify trends focusing on cur-rent information about the best palliative treatment,with an emphasis on the role of stenting. Self-expand-ing stent placement, either metal or plastic, is the mainmanagement option. However, this anatomical loca-tion creates some particular problems for stent safetyand effectiveness which may be overcome by properlydesigned novel stents. The stents ensure a good qual-ity of life and must be preferred over other alterna-tive methods of loco-regional modalities, i.e., externalradiation, laser thermal or photodynamic therapy. Al-though stent placement is generally a simple, safe andeffective method, there are sometimes complications,increasing the morbidity and mortality rate. Bypassoperative procedures have now been abandoned as afirst choice. The stomach instead of the colon must beused for a bypass operation when it is needed. Chemo-therapy, despite the toxicity, and intraluminal radiation(brachytherapy) have a well-defined role.展开更多

Our case is a 78-year-old male patient comes in with the dysphagia and weight loss, and on endoscopy(EGD) he is found to have an irregular intraluminal mass at the distal esophagus. With the deep EGD assisted biopsy, diagnosis of the verrucous carcinoma is made. Due to multiple co morbidities and possible infiltration to the pericardium, patient is taken for the esophageal stent placement and is being referred for the chemo-radiation treatment. The diagnosis can be very difficult to make with the superficial biopsies due to very non specific histological changes and requires very high clinical suspicion and deep mucosal biopsies are required for accurate diagnosis of the tumor. Chronic and local disease process is the main risk factor for the development of the verrucous carcinoma of the esophagus. Surgery is the treatment of the choice for the early stage tumor and advanced cases are treated with the palliation and possibly chemoradiation. The prognosis is usually guarded and needs long term follow up.展开更多
