再次显微输卵管复通术17例报道

对17例人工绝育后曾行输卵管复通手术失败病例,进行再次显微输卵管复通手术,经随访二年以上,宫内妊娠率41.18%(7/17)。手术后成功率与输卵管吻合部位有关,峡部与壶腹部吻合效果最差。作者指出再次显微输卵管吻合手术对由于原吻合部位闭锁病例有一定的价值。但需慎重考虑如何提高初次吻合术质量、防止术后粘连是十分重要。     

Hand and wrist imaging using a low-field dedicated MRI system

Summary Purpose of this study was to evaluate the diagnostic value of a low field dedicated MRI system in hand and wrist imaging. All 308 exams of the hand and wrist, that were performed on a low-field dedicated MRI system (Artoscan, Esaote Biomedica, Italy) in our institution in 1996, and high-field MRI exams performed in addition as part of the diagnostic work-up, were evaluated and correlated to final operative (n = 64) and histologic (n = 12) reports. 90 % of all low-field MRI scans stated a diagnosis according to clinical suspicion. In 62 % the clinical question was answered, and in 26 % additional pathologies were identified. An MR-diagnosis completely different from the clinical suspicion was stated in 2 %. High field exams contributed additional information in 6 of 36 patients. In 3 patients a tumor was not shown completely in the limited field-of-view of the dedicated low-field MRI-system. Frequency-selective fat-suppression pulse sequences and a better spatial resolution were the reasons for the additional information obtained in the other three patients. Low-field dedicated MR-imaging is a valuable method in the extensive work-up of the hand and wrist. Osseous, ligamentous and tendinous pathologies are well depicted. Large or infiltrative tumors should be referred to a high-field system.      

Treatment of iatrogenic biliary obstruction by balloon dilatation of a biliary jejunal fistula

Biliary obstruction and multiple hepatic abscesses occurred in a patient after ligation of a segmental branch of the right hepatic duct. The patient was successfully managed by transhepatic biliary drainage and balloon dilatation of an internal fistula that developed between the ligated duct and a Roux limb of jejunum. Internal biliary fistulas may be dilated using interventioanl radiologic techniques to permit nonobstructed bile flow. Implications for the nonsurgical treatment' of biliary strictures are discussed.

逆行岛状皮瓣修复手部软组织缺损

目的报道手部软组织缺损逆行岛状皮瓣修复方式的选择及临床效果。方法根据手部软组织缺损的不同部位，应用六种不同的手与前臂逆行岛状皮瓣进行修复。结果本组57块皮瓣中，除4块皮瓣远端部分坏死外，其余皮瓣成活良好，外观满意，弹性、质地良好，两点辨别觉6～12mm。结论手与前臂逆行岛状皮瓣切取简便，创伤小。根据手部软组织缺损不同部位，选择不同的逆行岛状皮瓣进行修复，可获得满意的临床效果。     

急诊左半结肠一期切除吻合术25例治疗体会

目的探讨急诊左半结肠切除一期肠吻合的可行性。方法腹腔探查完后，用布带结扎横结肠，游离肠系膜后，于预切除肠段的上端切开作肠外减压，挤压排空粪便，切除病变肠管，端端吻合，术后作肛管扩张，停留肛管引流，胃肠减压。结果全部病人预期痊愈出院，无发生吻合口漏和腹腔污染。结论该法有利于吻合口的愈合，增加左半结肠一期切除吻合的安全性，减少第2次手术痛苦，可推荐为左半结肠急诊切除一期吻合的良好方法。     

多序岩黄芪化学成分研究（Ⅳ）

目的研究多序岩黄芪(Hedysarum polybotrysHand.-M azz.)的化学成分。方法用柱色谱分离,用理化性质及波谱方法鉴定结构。结果从多序岩黄芪中分离鉴定了3个化合物:(1)白桦脂酸,(2)二十六碳酸,(3)蔗糖。结论化合物1和2为首次从该植物中分离得到。     

手部皮肤套脱伤的治疗

目的探讨手部皮肤套脱伤的治疗方法。方法2002年4月-2004年11月，治疗22例手部皮肤套脱伤患者，其中19例分别通过吻合血管、套脱皮肤修薄回植及多切口引流等方法进行修复。另有3例，因无法行套脱皮肤回植而采用腹部带蒂皮瓣修复。结果术后随访3个月-1年。19例套脱皮肤原位回植患者中，13例皮肤完全成活，4例有部分皮缘坏死，经中药换药后愈合，2例行切痂植皮术后治愈。手功能按ATN功能评分评定：优9例，良7例，中3例，优良率为84％，患者对手外形及功能满意。3例腹部皮瓣修复者，皮瓣全部成活。术后随访5个月-1年，手外形及功能明显差于皮肤原位回植者。结论尽可能地回植手部套脱皮肤，对手功能及外形的恢复具有重要意义。     

Recognition of potential morbidity after use of the radial artery as a conduit for coronary artery revascularization

The use of the radial artery as an alternative vascular conduit for coronary bypass surgery has become increasingly popular. The plastic surgery experience with radial forearm flaps has shown that sacrifice of the radial artery is not always a benign maneuver. The potential morbidity after using this conduit donor site in terms of hand dysfunction or wound healing problems can be significant, and frequently must ultimately be addressed as part of the role of the reconstructive surgeon. Case examples of skin necrosis, subsequent forearm wound infection and hypertrophic scarring after radial artery harvest are presented to introduce this as a real concern and to allow a review of the entire spectrum of potential problems in this regard. Any selection process where the radial artery may be chosen as the coronary revascularization conduit must anticipate these known donor site complications.
