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.     

白塞病并发动脉瘤12例的外科治疗体会

目的总结白塞病并发动脉瘤的外科手术和腔内治疗经验。方法对1977年6月至2006年3月收治的12例白塞病患者并发21个动脉瘤进行回顾性分析。腹主动脉瘤3个,升主动脉瘤1个,髂动脉瘤4个,髂动脉吻合口假性动脉瘤1个,股总动脉瘤3个,股浅动脉瘤2个,腘动脉瘤2个,椎动脉瘤1个,锁骨下动脉瘤2个。颈动脉瘤1个和肠系膜上动脉瘤1个。21个动脉瘤中,行外科手术14个,包括动脉瘤切除、人工血管或自体大隐静脉移植术12个,动脉瘤切除、病变动脉结扎术2个;行支架型人工血管腔内修复术6个;1个升主动脉瘤因患者全身情况差,行保守治疗。结果围手术期死亡患者2例,其中1例行外科手术,1例行腔内修复术。术后吻合口假性动脉瘤1例（1个）,其他部位新动脉瘤形成7个,下肢血管移植物闭塞2例,但患肢无明显缺血坏死。6例患者随访3-293个月,随访中位时间28个月,1例死于肺癌。结论白塞病动脉瘤一旦发生,需积极处理。术前、术后积极免疫抑制治疗可降低外科手术和腔内修复术后并发症发生。因术后有吻合口和其他部位假性动脉瘤复发及血管移植物闭塞可能,需长期随访、及时处理。

腹腔镜辅助小切口甲状腺结节手术的临床应用

Objective To study the feasibility, superiority and experience of minimally invasive laparoscopic-assisted surgery of the thyroid using ultrosonic scalpel. Methods In a period from January, 2006-August, 2008, 56 patients of the department of general surgery, the hospital of Heilongjiang Province were diagnosed as thyroid node. The size of the nodes ranged from 5.0 cm×4.2 cm to 3.5 cm×2.0 cm in uhrosonography. An incision of about 1.5-2.0 cm was made 1.0 cm above the suprasternal notch and the operation was performed with ultrosonic scalpel assisted with laparoscope. Partial thyroideetomy of lateral thyroid was performed in 20 cases, subtotal thyroidectomy in 25 cases, subtotal thyroidectomy of unilateral thyroid and partial thyroidectomy of contralateral thyroid respectively in 1 case, partial thyroidectomy of bilateral thyroid in 10 cases. Results All 56 cases have undergone minimally invasive laparoscopic-assisted surgery successfully in 50-146 min and no complications occurred. Fifty five cases were confirmed to be benign lesion pathologically. Conclusion Laparoscopic-assisted surgery of the thyroid is an effective with a good cosmetic result.     

神经导航在经单鼻孔入路垂体腺瘤切除术的应用

目的 探讨神经导航系统在经单鼻孔入路垂体腺瘤切除术中的应用技术及对鞍区解剖结构识别的价值。方法 对39例垂体腺瘤使用StealthStation神经导航系统进行指导定位、识别入路相关的解剖结构并引导手术操作。结果 平均注册误差为2．3mm（1．6～3．3mm），肿瘤全切除32例，次全切除4例，大部切除2例。部分切除1例。未全切除病例主要是肿瘤巨大、向海绵窦侵袭性生长、质地坚硬或血供异常丰富者。结论 神经导航系统提供了准确可靠的定位，能够准确指示中线结构、鞍底和颈内动脉，有效地减轻了创伤，使之成为良好的手术辅助工具。
