腹茧症的影像诊断

目的探讨腹茧症的影像特点，提高术前诊断水平。方法回顾性分析经手术病理证实的腹茧症6例，术前均进行立位腹部X线平片和腹部CT检查，4例同时行胃肠道钡剂造影，复习其影像表现。结果6例立位腹部X线平片中3例诊断为肠梗阻。4例胃肠道钡剂造影，均可见小肠交错盘绕成团，呈“菜花”状或“手风琴”状表现。6例CT检查，均可见小肠聚集成团，其周围可见膜样的囊状物将其包裹。结论对患者进行胃肠道造影时观察到“菜花”状征象，或CT检查时观察到小肠聚集成团被一层膜样物包裹，应考虑到腹茧症的可能。

对大肠癌术后早期炎性肠梗阻诊治的探讨

目的：探讨大肠癌术后早期炎性肠梗阻的特点及治疗方法；方法：分析10例大肠癌术后出现早期炎性肠梗阻的临床表现并进行综合保守治疗；结果：10例患者保守治疗全部成功；结论：术后早期炎性肠梗阻是一种非细菌性炎性肠梗阻，以发生在术后早期，腹胀、呕吐明显，腹痛轻或无为主要临床特点，治疗应采用保守治疗。     

Airway troubles related to the double-lumen endobronchial tube in thoracic surgery

Purpose Several case reports indicate critical respiratory complications in relation to the double-lumen endobronchial tube (DLT). A prospective survey for the airway problems in using the DLT is presented. Methods One hundred adult patients undergoing thoracotomy for lung cancer were investigated. Tube malposition and airway obstruction were searched using a fiber-optic scope. The endobronchial cuff was positioned just below the trachcal carina while the trachea was intubated with a DLT (Rüsch). The distances of displacement, from the tracheal carina to the bronchial cuff, were measured during anesthesia using an epidural catheter, which had marks every 5 mm. The distances for correcting the tube position were measured at both the bronchial cuff and the level of the teethPaO₂,PaCO₂ andSPO₂ were also measured. Results Malposition (displacement over 5 mm from the correct position) was found in 42 patients, and 40 of them were in a withdrawal direction, occurring at the postural change and during one-lung ventilation, especially during manipulation of the lung hilum. Correcting distances at the level of the teeth were 15.3–3-times longer than those at the bronchial cuff. Airway deformities and gradual withdrawal of the bronchial cuff were found in association with surgical manipulation. Obstruction occurred at the tips of the tracheal tube in four patients and the bronchial tube in six patients, and at the tip of both in two patients. Hypoxemia (PaO₂<60 mmHg) occurred in four patients and hypercapnea (PaCO₂>60 mm Hg) in two patients. Conclusion Most of the DLT obstructions were associated with withdrawal malposition. Great attention to DLT displacement and airway deformity is advised.     

肠梗阻的临床进展

将近5年来有关肠梗阻的新诊治方法作一综述，结论如下：①B超、CT和76％泛影葡胺口服造影等对肠梗阻诊断有重要临床价值。②腹腔镜小肠梗阻手术是最能体现微创技术优越性的手术之一。③EPII应以非手术疗法为主。     

Obturator hernias — Report of seven cases

Summary Obturator hernias comprise a rare group of abdominal hernias. They are often diagnosed when the small bowel has become obstructed and the patients are operated on without the causes of the obstruction being known. Although many techniques for closure of the defect are available, there is no agreement at the present time as to which is the procedure of choice.     

Laparoscopic gastrojejunostomy and endoscopic biliary stent placement for palliation of incurable gastric outlet obstruction with cholestasis

Background: For patients with incurable malignant gastric outlet obstruction and cholestasis, laparoscopic gastrojejunostomy combined with endoscopic biliary stent placement seems to offer a minimally invasive palliation. Methods: We retrospectively analyzed the data of 16 patients submitted to laparoscopic gastrojejunostomy. Laparoscopic gastroenterostomy was performed as an antecolic, side-to-side gastrojejunostomy with enteroenterostomy. In 12 patients cholestasis was relieved preoperatively by stent placement via endoscopy (n= 6, 37.5%), percutaneous access (n= 5, 31%) or bilioenteric anastomosis (n= 1, 6.25%). One patient needed a percutaneous Yamakawa prosthesis postoperatively. Results: Mean operative time was 126 min. There were no intraoperative complications. In one patient conversion to open surgery became necessary because of extensive adhesions. The only postoperative complication was bleeding from a trocar site requiring reintervention; there was no mortality. Median postoperative hospital stay was 7 days. Delayed gastric emptying was observed in 3 (18.7%) patients. Median survival was 87 days after the operation. All patients died from their primary disease but could maintain oral intake during the remaining survival time. Conclusions: We conclude that laparoscopic gastrojejunostomy and endoscopic or percutaneous biliary stenting provide a good functional result while impairing the quality of life only to a minimal extent.

162例气管插管患者的气道管理

笔者通过报道162例气管插管患者的气道管理，阐述痰痂形成的原因：(1)气道干燥，湿化不够。(2)吸痰管插入深度不够，吸痰不彻底。管理措施：(1)用金霉素眼膏润滑吸痰管，使之易于插入，保证吸痰管插入深度超过插管远端3-5cm。(2)预防气道干燥，注重湿化效果，重视吸痰环节。认为气囊不需定时放气，只需不定时调整气囊压力。     

输尿管镜治疗输尿管结石185例

目的探讨输尿管镜气压弹道碎石治疗输尿管结石的效果。方法2004年2月～2005年3月，我们对185例输尿管结石（其中伴肾绞痛96例）采用输尿管镜取石或气压弹道碎石进行总结和分析。结果失败12例，其中6例改开放手术，6例术后3d行体外冲击波碎石。一次碎石成功率93．5％（173／185），其中上段结石为75．0％（24／32），中段为95．8％（46／48），下段为98．1％（103／105）。肾绞痛者成功率为100％（96／96）。术中输尿管损伤率2．9％（5／173），其中3例（1．7％）中转开放手术。术后肾绞痛1例。全组随访6～12个月，平均10．2月，无复发。结论输尿管镜气压弹道碎石安全有效，并发症少，是治疗输尿管中下段结石的首选方法，尤其对肾绞痛者疗效更好。
