ABSTRACT
Objective To compare the effect of video-assisted minithoracotomy(VAMT)and video-assisted thoracoscopic surgery(VATS)for spontaneous pneumothorax.Methods 98 patiens with spontaneous pneumothorax allocated to VAMT or VATS were selected.The operation time,blood loss during operation,score of postoperative pain,time of postoperative drainage,postoperative hospital stay,surgery cost,rate of complication and recurrence were compared between the two groups.Results All patients were cured.The operation time,postoperative hospital stay and surgery cost were significantly different between VAMT and VATS groups(all P ＜0.05).The parameters of two groups were similar in score of postoperative pain,time of post-operative drainage,blood loss during operation,rate of complication and recurrence(all P ＞ 0.05).Conclusion VAMT was as effective as VATS,but the operation time,postoperative hospital stay and surgery cost was significantly better than VATS.
ABSTRACT
<p><b>OBJECTIVE</b>To analyze the causes of failure of esophageal stent implantation and explore technical improvement of re-implantation of esophageal stent (RIES).</p><p><b>METHODS</b>According to the conditions of the failed stent implantation, 32 patients who required RIES underwent placement of more appropriate esophageal stents with an improved implantation technique. The patients were followed up for 6 months after the operation to evaluate the effects of RIES.</p><p><b>RESULTS</b>The success rate of the operation was 96.9% in these cases, and the esophageal conditions including stricture and fistula were effectively relieved. During the 6-month follow-up, stent migration occurred in 4 cases (12.5%), and esophageal fistula in the upper edge of the re-implanted stent occurred in 2 cases. No stent loss, bleeding, or stricture was found in these cases.</p><p><b>CONCLUSION</b>The improved technique is effective for stent re-implantation after failed esophageal stent implantation with reduced complications associated with esophageal stenting.</p>
