【摘要】 目的 讨论胃充盈超声造影在胃溃疡患者术后的应用价值。 方法 2002年6月-2009年6月对因胃溃疡行手术的72例患者采用饮水法充盈胃进行术后超声检查随访，观察术后胃的容量变化、术后近期并发症及远期并发症。 结果 所有胃术后的患者，近期胃容量较前减少60%～70%，随着时间的延长，容量逐渐恢复，最大恢复至术前的50%。吻合处胃壁僵直，蠕动波消失。十二指肠残端漏2例，近期吻合口狭窄5例，胃瘫综合症3例，吻合口反流40例，有临床症状的患者10例，无临床症状的患者30例，复发性溃疡1例，未发现残胃癌及远期吻合口梗阻。 结论 胃充盈超声造影是胃溃疡术后简单易行的随访方法，具有重要的临床应用价值。【Abstract】 Objective To evaluate the use of contrast-enhanced ultrasonography of gastric filling in gastric ulcer patients after the operation. Methods A total of 72 patients who underwent the operation due to gastric ulcer between June 2002 and June 2009 were selected. We used water-drinking method for filling stomach to perform the ultrasonic examination and the patients were followed up. The post-operation changes in the capacity of the stomach, postoperation complication and long-term complication were observed. Results The reduction of recent stomach capacity was 60%-70% in of the patients after the operation. As time goes on, the capacity gradually recovered, and the largest recovery was 50%. Anastomosis gastric wall was stiff, and peristaltic wave disappeared. Drain off residual duodenum was found in 2 patients, anastomotic stricture near was in 5, delayed gastric emptying was in 3, anastomotic reflux was in 40, clinical symptoms was in 10, no clinical symptoms was in 30, and recurrent ulcer was in 1. No gastric remnant cancer or long-term anastomtic obstruction was observed. Conclusion Contrast-enhanced ultrasonography of gastric filling is a simple and practicable ultrasound follow-up method after gastric ulcer.
目的 探讨环氧化酶-2（COX-2）在幽门螺杆菌（Hp）感染与非感染性胃溃疡及胃癌的表达。 方法 选择绵阳市404医院消化内科2011年2月－2012年2月的门诊及住院患者，用免疫组织化学方法检测196例经胃镜和组织病理学检查明确为胃溃疡（病理分型：肠上皮化生、异型增生）、胃癌及正常胃黏膜者的胃黏膜COX-2蛋白的表达，比较各病理分类之间及Hp感染与非感染之间COX-2蛋白表达的差异。 结果 胃溃疡（肠上皮化生、异型增生）、胃癌组的炎症细胞、腺上皮细胞、癌细胞及极少量正常黏膜上皮细胞中有COX-2表达。从正常胃黏膜-胃溃疡（肠上皮化生、异型增生）-胃癌COX-2的阳性表达有逐渐增强的趋势（P＜0.05）。Hp阳性组COX-2的阳性表达高于Hp阴性组（P＜0.05），胃癌组COX-2的阳性表达高于胃溃疡组（P＜0．05）。 结论 COX-2在胃癌的表达高于胃溃疡。Hp感染可诱导COX-2过度表达。
ObjectiveTo study the serum transforming growth factorβ1 (TGF-β1) and interleukin-23 (IL-23) expression in the patients with chronic gastric ulcer or gastric cancer, and to investigate the clinical value of TGF-β1 and IL-23 on the prevention and treatment of gastric cancer. MethodsThe serum levels of TGF-β1 and IL-23 in cancer group (83 cases), gastric ulcer group (184 cases), and control group (58 cases) were detected by using ELISA assay method. The difference of serum TGF-β1 and IL-23 levels in patients with gastric cancer with different pathological parameters were compared. ResultsThe serum levels of TGF-β1〔(15.96±3.92) ng/mL〕and IL-23〔(645.25±234.18) ng/mL〕in gastric cancer group were higher than those of the gastric ulcer group〔(10.10±3.58) ng/mL, (496.10±108.32) ng/mL〕and normal control group〔(9.87±2.86) ng/mL, (372.75±89.27) ng/mL〕, the difference were statistically significant (P < 0.05). The levels of serum TGF-β1 in gastric cancer patients of stageⅠ-Ⅱ, ⅢandⅣwere successively increased, and the differences were statistically significant (P < 0.05). The levels of serum TGF-β1 in poorly differentiated gastric cancer or with lymph node metastasis patients were higher than those in high-middle differentiation or without lymph node metastasis patients, the difference were statistically significant (P < 0.05). There were no significant difference in the levels of serum TGF-β1 between different tumor diameter and different location (P > 0.05). The level of serum IL-23 in patients with stageⅠ-Ⅱwas higher than that in stageⅢandⅣ, the difference was statistically significant (P < 0.05). Ther were no significant difference in serum IL-23 levels between the different degree of differentiation, lymph node metastasis or not, different tumor diameter and different location of the tumor (P > 0.05). ConclusionTGF-β1 and IL-23 have important reference value in judging the stage and malignancy degree of gastric cancer.
Objective To evaluate the effect of ultrasound guided percutaneous drainage on acute perforation of gastroduodenal ulcer in elderly patients. Methods The clinical features, treatments, and the curative effects of 86 elderly cases (≥65 years) of acute perforation of gastroduodenal ulcer in our hospital between January 2004 and October 2009 were retrospectively analyzed. Twenty-one cases were treated by ultrasound guided percutaneous drainage (drainage group), and 65 cases were treated by exploring operation (operation group). Results Drainage group was cured and had no complications. In 15 patients which accepted recheck one month after drainage, gastroscope showed the ulcer healed in 12 cases， and improved in 3 cases. In operation group, 63 cases were cured and 2 cases died. Compared with the drainage group, there was no significant difference in cure rate (Pgt;0.05). However, 11 patients had operative complications in operation group, which was significantly more than that in the drainage group （Plt;0.05）. In 45 patients which accepted recheck one month after operation, gastroscope showed the ulcer healed in 38 cases， and improved in 7 cases. Conclusion For elderly patients with acute perforation of gastroduodenal ulcer， if the patients do not fit for exploring operation， ultrasound guided percutaneous drainage is proved to be a simple, safe, and effective means.
