Surgical treatment for ureterocele with special reference to lower urinary tract reconstruction

OBJECTIVES: We reviewed the results of surgical treatment for children with ureterocele, especially addressing the importance of the lower urinary tract reconstruction. METHODS: We present medical records of 91 children with ureterocele (31 with the intravesical type, and 60 with the ectopic type) treated during the last 14 years. As the initial treatment, we carried out transurethral incision of the ureterocele (TUI). In patients with persistent reflux, breakthrough urinary tract infection (UTI), or signs of bladder outlet obstruction due to a collapsed cele wall, we recommended that patients undergo lower urinary tract reconstruction irrespective of the renal function involved in ureterocele. The average follow-up period was 5 years (ranging 1 year and 6 months to 14 years). RESULTS: Transurethral incision of the ureterocele was carried out as the initial treatment on 68 patients (75%). A total of 34 patients (21 intravesical [68%] and 13 ectopic [22%]) were followed medically after TUI alone. Reconstruction of the lower urinary tract was carried out in 59 patients (65%). Nephroureterectomy combined with bladder level reconstruction was carried out in four children with single system and non-functioning kidney. Follow-up voiding cystourethrography showed that only one girl had reflux, which disappeared after the first follow-up examination. Postoperative UTI occurred in 12 patients (20%) with ectopic ureterocele. Voiding dysfunction was suspected in eight patients. CONCLUSION: We believe that the primary objective for patients with ureterocele, especially of the ectopic type, is to reconstruct the original pathology of the lower urinary tract that may give rise to reflux, obstruction, or abnormalities of urination. Although surgery at the bladder level can be challenging, the lower urinary tract reconstruction successfully corrects the vesicoureteral reflux and bladder outlet pathology under a cosmetically acceptable incision.

老年重症急性胰腺炎手术治疗探讨

目的：讨论老年重症急性胰腺炎的手术治疗。方法：我院1984年1月－2000年10月共收治60岁以上手术证实的重症急性胰腺炎26例，本对其手术治疗的方法和时机以及相应的并发症和死亡率进行回顾性分析。结果：本组术后死亡6例，其中4例死于MOF，2例死于ARDS。在发病24小时内手术8例中无1例死亡，24－36小时内手术14例有2例死亡，36小时后手术4例均死亡。结论：老年重症胰腺炎患多伴有心、肺、肾等重要器官慢性疾病，脏器代偿功能差，较易出现MOF，因此如有手术指证或经短期非手术治疗效果不明显，应及时手术，并在术中和术后采用合理的治疗措施，有利于减少术后并发症，降低手术死亡率。     

The effect of prior back surgery on surgical outcome in patients operated on for lumbar spinal stenosis a matched-pair study

Summary It has been widely observed that the outcome after repeat lumbar surgery is rarely comparable to that of primary surgery. In particular, the results of repeat surgery for lumbar spinal stenosis (LSS) have not been favourable. We used a matched-pair format in an attempt to decrease the confounding factors so as to determine as exactly as possible the effect of prior back surgery on the LSS patients surgical outcome. The matching criteria were sex, age, myelographic findings, major symptom, and duration of symptoms. From one group of 251 patients without prior back surgery (SO patients) and another of fifty-three patients with one preceding back operation (RS patients), forty-one similar matched patients pairs (one SO and one RS-patient) were formed.There were 8 female and 33 male pairs. The mean age of the SO patients was 51.6 and of the RS patient 51.4 years, and the mean follow-up time was 4.6 and 4.4 years. The assessment of outcome was based on a subjective disability questionnaire. The SO patients fared significantly better than the RS patients (32.1 versus 41.3, P = 0.026). A short time interval between operations in the RS patients had a worsening effect on outcome, but this trend was not significant.We concluded that one preceding back operation had a worsening effect on the outcome of patients operated on for LSS. As a whole, the results of RS patients were unfavourable. The proper time for achieving good surgical results in LSS patients is the initial operation.     

应用抗凝剂的心脏瓣膜置换患者接受胆道手术的术前处理

目的总结瓣膜置换患者行胆道手术的术前用药方法。方法对38例瓣膜置换后在服用华法令过程中因胆道疾病需行择期手术治疗的患者随机分为2组,肝功能正常组(A组)23例、肝功能不正常组(B组)15例均于术前3d停服华法令,B组术前12h肌注VitK110mg。术前无应用华法令历史的患者115例做为对照组。结果38例患者停药2d后A组血浆凝血酶原时间与对照组差异无显著意义,B组于术前12h肌注VitK110mg后,血浆凝血酶原时间与对照组相比差异也无显著性意义。结论瓣膜置换患者在抗凝期间行胆道手术,只要准备充分,围手术期是安全的。

完全性房室间隔缺损的外科治疗

目的回顾性总结手术治疗完全性房室间隔缺损的经验。方法112例病儿,≤6个月43例(38%,X组),>6个月69例(62%,Y组)。85例行心导管检查。Rastelli A型89例,Rastelli B型10例,Ras- telli C型13例。手术技术分单片法,双片法和简化单片法。术中经食管超声检查发现异常而即刻再次手术者7例(二尖瓣反流4例,二尖瓣狭窄2例,左室流出道梗阻1例)。术后入重症监护室,左房压8～21 mm Hg,中心静脉压7～12mm Hg。呼吸机平均应用47h,监护室平均滞留6.3d。结果室间隔缺损残余分流(直径>2mm)13例,二尖瓣中度反流12例,完全性房室传导阻滞4例。院内死亡6例(X组1例,Y组5例)。术后随访91例(81%),随访1～5年,平均2.3年。1例术后1年因肺炎心衰死亡,1例术后2年因二尖瓣中-重度反流而换瓣。结论院内死亡率提示,小于6月龄完全性房室间隔缺损病婴手术是安全的。随着年龄增大,瓣膜成形效果、肺动脉高压的预后可能会更差。双片法修补室间隔缺损较易发生残余漏(9例,18%),简化单片法出院时二尖瓣关闭不全发生率明显高于另外两种方法(6例,16%)。
