应用预控出血的包皮中远段环形剥除术治疗包皮过长

Objective To investigate the middle and distal circum peeling with bleeding control technique for redundant prepuce. Methods The middle and distal part of prepuce was eireum peeled with bleeding control and electrical scalpel. More preputial inner plate was reserved. Results From January 2004 to July 2008, 51 patients with redundant prepuce were treated with this procedure. The average blood loss was 1 ～2 ml with minimal edema. The proportion of inner and outer plates was suitable. Conclusions This teelmique has the advantages of minimal blood loss and slight edema. The cosmetic result is also satisfactory.

包皮过长和包茎组织中触觉小体观察

目的观察包茎和包皮过长组织中触觉小体差异情况。方法收集21~25岁年龄组包皮标本44例,按包皮解剖形态分为:①包茎组21例;②包皮过长组23例。用免疫组化方法对两组包皮标本中的触觉小体进行染色,在放大100倍的视野下观察和统计两组包皮标本中触觉小体总数以及视野的总数,并用卡方检验对两组间的差异进行统计学分析。结果两组标本中,分别有8个(8/21包茎组)和10个(10/23包皮过长组)标本中未发现触觉小体,其差异无显著性(P=0.717)。包茎组和包皮过长组中触觉小体的密度分别为33.1%和21.1%,差异具显著性(P=0.022)。结论包茎中触觉小体密度较包皮过长明显升高可能是一种生理性代偿机制,而两种包皮组织中触觉小体的消失可能遵循同一规律。     

Laparoscopic-assisted abdominoperineal proctosigmoidectomy for rectal prolapse

The inability to completely mobilize the redundant colon in perineal rectosigmoidectomy (Altemeier's procedure) for full-thickness rectal prolapse is a main contributor to the recurrence rate associated with the procedure. However, the presence of a redundant sigmoid after the Ripstein procedure or other rectal sling operations is the main cause of the high rate of postoperative constipation and stool impaction. Low anterior resection as the definitive treatment is associated with the higher morbidity of laparotomy and the risk of anastomotic leak. We describe a laparoscopic-assisted surgical approach which combines the benefits of completely resecting the redundant sigmoid colon as well as the performance of extraperitoneal anastomosis at the level of the anus.

CO2激光包皮环切"美容"术1624例

目的探讨将整形美容的方法引入CO2激光包皮环切术中治疗包皮过长及包茎的疗效。方法在行常规CO2激光包皮环切术中,将整形美容的方法贯穿始终。结果1624例中,1593例术后未发生并发症,伤口愈合良好,外形美观;7例术后6h内发生出血,24例术后9~20d切口裂开。结论将整形美容的方法引入CO2激光包皮环切术中,伤口愈合良好,外形美观,疗效满意。     

A multi-input/multi-output optimal PI controller for redundant robots in the presence of flexible disturbances

The two-stage synthesis of a multi-input/multi-output optimal proportional-integral (PI) controller is described for linear, time-invariant systems. In the first stage the PI controller is designed by solving a steady state algebraic Riccati equation. As a result, the optimal cost is expressed in terms of the system's constant output set-points. In the second stage the cost is further reduced by optimally selecting the output set-points to minimize a static quadratic performance index subject to linear algebraic constraints. The design framework is applied to a planar redundant robotic manipulator equipped with four joints and mounted at the tip of a long flexible arm. We then address the problem of self-motion control in the presence of vibratory disturbances.     

阴茎皮肤和包皮动脉的应用解剖

目的：为带蒂阴茎皮瓣修复尿道下裂提供解剖学基础。方法：对３０例成年男性阴茎的动脉分布进行解剖观察。结果：阴茎背浅动脉的一级分支集中在阴茎的近、中１／３段内，其再分支呈扇形分布于阴茎皮肤和包皮。阴茎背浅动脉的分支首先进入包皮外板，经包皮内外板交界处，返折进入内板。阴茎背浅动脉有三种配布类型：①单支分布型（３０％）；②对称分布型（４０％）；③非对称分布型（３０％）。阴茎背动脉在距阴茎冠状沟０．５～１．５ｃｍ范围内发出穿支至包皮内板。结论：用阴茎远侧皮肤和包皮作纵行带蒂岛状皮瓣具有可行性。     

改良袖套式包皮环切术治疗包皮过长28例报告

目的探讨改良袖套式包皮环切术治疗包皮过长患者的疗效。方法采用改良袖套式包皮环切术治疗包皮过长患者28例。术中先标志包皮切除长度,在直视下于包皮内、外板作两个互相平行的环形切口,将两切口间包皮条用小圆头刀锐性剥离,保留完整肉膜及皮下浅层血管,并保留完整的包皮系带。结果28例术中出血极少,切口整齐,术后伤口无水肿,无继发性出血及感染,均一期愈合,切口瘢痕少,阴茎外形美观。结论改良袖套式包皮环切术对包皮过长患者治疗效果满意。
