升主动脉成形术中期效果分析

Objective Reduction ascending aortoplasty is an alternative procdure to the replacement of the ascending aorts in case of ascending aorta dilation. However,its applicabikity is still under debate.This retrospective study was designed to evaluuate the midterm follow-up of unsupported ascending reduction aortoplasty for of the ascending aorta in petients with aortic valve dis- ease.Methods From October ,1996 to April,2007, a total of 54 patients with aortic valve disease and dilatation of the ascending aorta underwent unsupported reduction aortoplasty in combination with aortic valve replacement at our institution The diameter of the ascending aorta was measyred before and early after sugery and then later between 13 and 96 menths [mean (23 ±16)months] posto- perativeiy using echocardiography.Results Two patients were dead with thean overall perioperative mortality rate was of 3.7%. The reduction aortoplasty decreased the diameter of the aorta from (45.77±6.02) mm p～eope～afive]y to (34.67 ～4.81) mm early after surgery (P<0.01). During follow-up, the diameter d aorta increased from (34.67±4.81) mm early after surgery to (37.65± 6.35) mm after a mean follow-up of (23±16) months (P<0.01), including the diameters are greater than > 45 mm within 5 pa- tients. Aortic stenosis and an early postoperative diameter greater than 40 mm m'e independent risk factors for redilatation. Conchusion Because of the unsatisfied midterm follow-up redilation of unsupported reduction aortoplasty for dilation of the ascending aorta with aortic valve disease, this group of patients needs continued intimate fallow-up or even reoperation. The patients of stenosis is the surtable indication for RAA, and it is necessary to reduce the diameter of aorta to be lees than 40 mm to prevent redilation.     

胃癌累及胰腺的外科治疗与预后(附120例报告)

目的探讨胃癌累及胰腺的外科治疗方法与预后的关系。方法回顾性分析我院1984年6月～2003年10月手术治疗累及胰腺的胃癌120例。结果本组120例中,根治切除组41例,姑息切除组23例,未切除组56例。根治组41例中经病理证实胰腺有癌细胞浸润者30例,占73.2%,淋巴结转移率为85.4%。其中No10、11淋巴结转移率为73.1%。术后102例得到随访,随访率为85%,1、3、5年的生存率分别为:根治切除组为73%、37%、17%,姑息切除组为22%、9%、4%,未切除组为9%、2%、0%。根治切除组1,3年生存率明显高于姑息性切除组和未切除组(P<0.05),5年生存率明显高于未切除组(P<0.01),但与姑息性切除组无显著性差异。姑息性切除组和未切除组1、3年生存率无显著性差异,但5年生存率明显高于未切除组(P<0.01)。结论胃癌累及胰腺的根治切除可提高1,3年生存率,选择合适的适应征是关键。姑息切除有助于改善生存质量,对改善预后意义不大。

Minimum incision endoscopic nephrectomy for giant hydronephrosis

Five consecutive patients with symptomatic giant hydronephrosis underwent minimum incision endoscopic nephrectomy. The originally huge renal specimen was retroperitoneally mobilized using both of endoscopy and direct vision, without the use of trocar ports or gas insufflation, via a single minimum incision that narrowly permitted extraction of the specimen. The specimen was successfully extracted from the incision in all patients. Technically, proper deflation of the hydronephrotic sac facilitates mobilization and enables extraction of the specimen. Median (range) size of incision, operative time, and estimated blood loss were 4 cm (3-5), 205 min (156-222), and 210 mL (110-350), respectively. No patient required blood transfusion or encountered operative complications. Postoperative convalescence was short and uneventful; all patients resumed oral intake and ambulance on the day following surgery, and were physically dischargeable from hospital after 2-3 postoperative days. Thus, this technique is a feasible, minimally invasive and safe procedure for symptomatic giant hydronephrosis.     

Head-to-head comparison of retropubic, perineal and laparoscopic radical prostatectomy

OBJECTIVE: As more patients are diagnosed with prostate cancer at an early stage, it is becoming increasingly important to refine the technique of surgical excision. For this purpose we have generated objective data comparing three different surgical approaches used by three experienced surgeons. METHODS: We prospectively compared three contemporary personal series of 50 consecutive radical prostatectomy (RP) patients. The health-related quality of life was evaluated preoperatively and in months 1, 3, 6, 12 and 24. RESULTS: Considering in turn the patients undergoing retropubic, perineal and laparoscopic RP, the median procedure time was 2 h and 27 min, 1 h and 50 min and 4 h, with a transfusion rate of 2, 0 and 8%, respectively. In the perineal group there were more wound infections. Median catheter drainage was 7, 10 and 7 days and zero, 13 and one patients needed reinsertion of a catheter. Early continence varied considerably, with 57.4, 11.4 and 6.3% of patients pad-free after 1 month, but there were no differences in social continence (zero or one pad) with 97.8, 97.8 and 91.9% after 2 years. The Litwin score for incontinence (preoperative minus postoperative) was -24, -41 and -63% after 1 month and -13, +3 and -29% after 2 years. Twenty-nine, five and 15 patients had a preoperative five-item version of International Index of Erectile Function (IIEF-5) score of > or = 17 points and a nerve-sparing procedure. After 2 years, 48.1, 0 and 0% had an IIEF-5 score of > or = 17 points without the use of phosphodiesterase type 5 (PDE-5) inhibitors, but when including patients using inhibitors there were no significant differences. CONCLUSIONS: A comparison of morbidity, short-term convalescence and long-term side-effects of different surgical techniques is strongly biased by both the preoperative status of patients and the skill of the surgeons. Overall, we found some differences in the short-term results (e.g. early continence) and comparable long-term results.     

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.
