后腹腔镜手术治疗嗜铬细胞瘤

目的探讨后腹腔镜手术治疗嗜铬细胞瘤的适应证及手术安全性. 方法采用后腹腔镜手术治疗肾上腺嗜铬细胞瘤患者15例(双侧2例),腹主动脉旁嗜铬细胞瘤1例.对照组为开放手术治疗的肾上腺嗜铬细胞瘤16例,腹主动脉旁嗜铬细胞瘤1例.结果后腹腔镜手术组16例患者行后腹腔镜手术18例次,17例次取得成功,1例因术中出血改行开放手术.肿瘤最大径2.0～6.5(3.8±1.6)cm.手术时间45～150(85±31)min,出血量10～100(32±22)ml.术后吗啡用量0～40(12.5±7.8)mg;术后恢复进食时间1～3(1.8±0.7)d;下床活动时间2～3(2.3±0.5)d;术后住院时间4～9(6.5±1.3)d.开放手术组肿瘤最大径1.5～6.0(4.3±1.3)cm.手术时间90～240(155±39)min,出血量50～600(273±105)ml,9例输血.术后吗啡用量10～120(61±24)mg;术后恢复进食时间2～4(2.9±0.5)d;术后下床活动时间3～6(4.8±0.7)d;术后住院时间8～11(8.8±0.9)d.结论对于有一定腹腔镜手术经验者,后腹腔镜手术并不增加嗜铬细胞瘤手术的危险性,且具有手术时间短、出血少、创伤小、疼痛轻、康复快等优点.该法有望成为治疗肾上腺嗜铬细胞瘤的首选手术方法.     

A novel access method for endovascular procedures in the porcine model

Objective To evaluate the use of the saphenous artery as an alternative access for endovascular procedures in the porcine model. Methods Fourteen adult pigs (25-35kg) were used in this study, 3 pigs from an acute study and 11 from chronic studies. A 2-3 cm incision was made and a saphenous artery cutdown was performed in 24 sides. Micropunc ture sets (Boston Scientific) or 18 G puncture needles were used to access the artery. Different sizes of introducers (4-7F) were used to establish endovascular access. Angiographic catheters were then used to confirm if the access was usable. Four saphenous arteries were explanted in the pigs from a chronic study 4 to 28 days after surgical procedure. Results The saphenous artery was very easy to expose and 4-5 F introducer sheaths were able to be inserted to establish access for endovascular procedures in the pigs. The saphenous artery was unable to accomodate an introducer with a size larger than 6 F. Four saphenous arteries were injured when 5 and 6 F introducers were used, but angiographic procedures could still be performed. Morphologic evaluation of the explanted arteries demonstrated occlusion of the saphenous arteries without injury or disruption of the adjacent femoral arteries. Conclusion The saphenous artery can be used as an access site in pigs for angiographic and interventional procedures if the catheter size is less than 6 F. This vessel is easier to access and can preserve the femoral artery for repeat procedures in the future.

Breast augmentation with silicone implants: the role of surgical drainage—report on 502 consecutive patients

Breast augmentation is one of the most frequently performed cosmetic surgery procedures worldwide. We report on a series of 502 consecutive cosmetic breast augmentations by a single surgeon, using both the submuscular and submammary approaches. A vacuum drain was placed in the surgical pocket at the end of the procedure. The drain fluid collection was recorded immediately after the surgery and the following day before removal. A tenfold increase in the amount of fluid collection was noted in the drain’s reservoir. Thirteen patients presented with minor wound healing problems at the second postoperative follow-up, which were treated conservatively; two of them had the implant removed and replaced after 2 months. There were only two capsular contractions at 1-year follow-up. We focus our discussion on the drainage in the early postoperative period and conclude that the routine use of a surgical drainage reduces the risk for complications. Based on our findings, we advocate that short-term routine use of a surgical drain is advisable.     

贲门失驰缓症介入治疗的疗效评价

目的：评价贲门失弛缓症球囊扩张介入治疗的疗效。方法：对20例贲门失驰缓症患者行球囊扩张术。结果：20例患者共进行了31次球囊扩张，人均1．5次（其中12例扩张1次，5例扩张2次，3例扩张3次）。术后患者吞咽困难明显缓解，主要并发症为疼痛和返流。术后随访无症状期为3－13个月。结论：球囊扩张术是治疗门失弛缓症的有效方法。

MRI测量颈胸角在选择颈胸段脊柱手术入路中的临床应用

目的 :探讨在颈胸段脊柱术前应结合患者的颈胸段MRI的个体特征和疾病情况 ,选择手术创伤最小的手术入路。方法 :共 76例患者 ,其中 2 6例为颈胸段脊柱损伤 ,35例为颈胸段脊柱肿瘤 ,脊髓型颈椎病 12例 ,以及 3例颈胸段椎板减压术后后凸畸形。男 4 7例 ,女 2 9例。平均年龄 4 5 5岁 ,年龄范围 19～ 6 5岁。同时抽取 95套颈胸段MRI片。作胸骨上切迹向后水平延长线和胸骨上切迹向后上方至C7T1椎间盘前缘中点的连线 ,测量两线之夹角 ,称为颈胸角 (cervicothoracicangle ,CTA)。结果 :CTA平均为 4 7 6 4°(范围 2 5°～ 73°)。大于此平均角度且病灶在胸骨切迹水平线以上时可考虑低位下颈椎入路 ,5 0例 ;CTA较小 ,且病灶范围广 ,或尚累及T3 、T4,可以考虑经胸骨柄入路 ,13例 ;病灶范围广泛 ,经全胸骨入路 3例 ;Ⅰ期或Ⅱ期前后联合入路 5例 ;经右侧肩胛下后外侧胸腔入路 5例。结论 :颈胸段脊柱手术应尽量选择低位下颈椎入路等创伤较小的入路 ,其次考虑经胸骨柄入路。长节段脊柱受累的患者才考虑经右侧肩胛下后外侧胸腔或经全胸骨等创伤较大的入路。术前可以结合患者的病灶累及范围和颈胸手术角等MRI影像学表现 ,从而利于选择最合适的手术入路 ,减少手术风险、手术创伤和并发症 ,利于患者早日康复
