Laparoscopic repair of a perforated marginal ulcer 2 years after gastric bypass

The authors present the case of a 43-year-old women who underwent a laparoscopic gastric bypass in 2003 for morbid obesity. They report that 2 years later, she had maintained significant weight loss, but had developed acute abdominal pain, followed by nausea and emesis. In the emergency room, she had diffuse tenderness, tachycardia, and leukocytosis. After initial resuscitation, a computed tomography was performed, which showed free air above the liver and thickened small bowel loops. She was brought emergently to the operating room for laparoscopy. At surgery, turbid fluid and inflamed small bowel loops were seen. A perforated marginal ulcer was discovered in the Roux limb, approximately 2 cm distal to the gastrojejunal anastomosis. The perforation was oversewn primarily and patched with omentum. The repair was tested by intraoperative endoscopy. A gastrostomy tube also was placed within the gastric remnant for enteral access. The patient did extremely well postoperatively, and had an uneventful postoperative course. She was discharged on postoperative day 4. The gastrostomy tube was removed at 1 month, and at this writing, she remains well since surgery. An upper endoscopy at 2 months was completely normal, and the Helicobacter pylori test results were negative. The gastric pouch had not significantly enlarged since initial surgery, as indicated by both endoscopy and barium study. Marginal ulcer is reported to be 0.6% to 16% after laparoscopic gastric bypass [1]. Etiologies include gastrogastric fistula, excessively large gastric pouch containing antral mucosa, H. pylori infection, nonsteroidal antiinflammatory use, and smoking [2]. Unfortunately, none of these applied to the reported patient. Because her exact etiology remains unknown, she at this writing continues to receive proton pump inhibitor therapy.

高频超声诊断新生儿卵巢增大、并腹股沟疝的临床意义

新生儿期卵巢增大,可形成卵巢囊肿、影响卵巢进入正常位置而形成腹股沟疝,导致小儿性早熟,影响小儿身高及心理发育等。自2006年1月-6月我们连续发现5例新生儿卵巢增大,予以报道。1材料与方法临床资料见表1,应用彩色多普勒超声诊断仪:Philps HD、HDI 5000,高频探头7-10mmHz。行常规下腹部及腹股沟、会阴区扫查。2结果超声检查所见及诊断结果见表1。表1 5例临床资料与超声检查结果比较异及丘脑-垂体-卵巢器质性病变产生过多激素,刺激胎儿卵巢内卵泡增生过大、内液潴溜,是导致卵巢增大的原因[3]。5例新生儿8枚卵巢增大的原因分析,说明胎儿期…
