婴儿主动脉缩窄合并心内畸形的一期矫治

目的总结婴儿主动脉缩窄（CoA）合并心内畸形一期矫治的手术方法和临床经验。方法2001年1月至2006年1月，对28例CoA合并心内畸形患者行一期手术矫治。CoA为导管前型18例，邻近或正对导管处10例；伴主动脉弓发育不良6例，动脉导管未闭22例。合并的心内畸形包括：室间隔缺损16例、室间隔缺损＋房间隔缺损5例、完全性房室间隔缺损3例，完全型大动脉错位伴室间隔缺损（D—TGA／VSD）2例，右心室双出口2例。采用左胸后外侧联合胸骨正中切口（双切口）径路手术12例，胸骨正中切口径路（单一切口）手术16例。采用缩窄段切除端端吻合术20例，Gore—Tex补片扩大成形术4例，左锁骨下动脉翻转扩大成形术4例。结果全组无手术死亡，术后呼吸机辅助呼吸时间7h～13d，住ICU时间3～18d。因术后心脏扩大延迟48～72h关胸4例，术后发生急性肾功能衰竭行腹膜透析3例，吸入一氧化氮（NO）治疗重度肺动脉高压3例。术后下肢收缩压高于上肢10～20mmHg18例（64．3％），收缩压上、下肢相差不大8例（28．6％），上肢分别高于下肢15mmHg和20mmHg2例（7．1％）。所有患者均得到随访，随访时间3～50个月，1例D—TGA／VSD患者因重度三尖瓣反流、肺部严重感染和呼吸功能衰竭于术后3个月死亡；其余27例患者恢复顺利。心脏超声心动图提示：1例采用端端吻合法、1例采用Gore～Tex补片扩大成形术的患者在CoA纠治处仍存在压差，分别为25mmHg、28mmHg，均未再次手术。结论一期手术矫治CoA合并心内畸形可以缩短疗程，有利于患者术后心、肺功能的恢复，避免二次手术的痛苦，降低治疗费用。可采用单一胸骨正中切口或胸骨正中联合左胸后外侧切口完成手术。

Amputation of a crossover 2nd toe in the presence of hallux valgus

Background: There are many surgical procedures for the correction of hallux valgus and crossover 2nd toe deformity. Amputation of a crossover 2nd toe is often performed as a salvage procedure if the primary 2nd toe corrective procedure fails.Aims: To assess the outcomes of amputating a crossover 2nd toe in the presence of hallux valgus in elderly patients above 70 years old; as a primary procedure.Materials and methods: Seven patients (8 ft) underwent amputation of their crossover 2nd toe. A disease specific questionnaire using a Visual Analogue Scale (VAS) was implemented measuring pain, deformity, discomfort, and walking distance.Results: The mean age of the patients was 82 years old, range 74–89 years old. Amputation of the 2nd toe significantly reduces pain, discomfort and the appearance of deformity, there was no difference in the patient’s walking distance after surgery.Conclusion: We recommend this type of surgery as a primary procedure in elderly patients above 70 years old, if the first ray is not causing symptoms.

Apical vault repair, the cornerstone or pelvic vault reconstruction

Pelvic organ prolapse remains a difficult problem for pelvic reconstructive surgery. Before new surgical procedures can be developed a good understanding of pelvic anatomy is necessary. It is widely held that the etiology of pelvic organ prolapse is secondary to stretch neuropathy following childbirth and chronic cough or constipation. Several transvaginal and transabdominal procedures have been developed over the years. With the increasing use of laparoscopy, a new variation on existing culdeplasty techniques has been developed. Following anatomical principles, the apical vault repair reestablishes the pericervical ring at the vaginal apex. The incorporation of pubocervical fascia, uterosacral-cardinal ligament and the rectovaginal fascia provides a strong anchor for the vaginal apex. In addition, the repair should help prevent future transverse cystocele, rectocele, enterocele and apical vault prolapse. Early outcome studies suggest that the apical vault repair should be used routinely with laparoscopic urethropexy, laparoscopic hysterectomy and the repair of pelvic organ prolapse. Good apical vault support is considered the cornerstone of pelvic reconstruction.     

Laparoscopic partial fundoplication vs laparoscopic Nissen-Rosetti fundoplication

Background: Since 1992, all patients at our institution who have met standard accepted criteria for surgical intervention for complicated gastroesophageal reflux disease have been entered into a prospective sequential clinical study to evaluate outcomes of the laparoscopic approach to the Nissen-Rosetti procedure and a modified Toupet procedure. Methods: A standardized workup with upper GI series, esophagography, and endoscopy was used in all patients. Manometry, pH testing, and other special tests were used selectively. A measuring technique was used to determine wrap size without the use of dilators. The short gastric vessels were left intact in all patients. A cosurgeon approach was used, with technical factors described herein. Results: Some 226 of 231 cases were completed laparoscopically (98%)—125 patients in the Nissen-Rosetti group and 101 in the partial fundoplication group. There were no clinical failures in either group. The partial fundoplication group performed better than the Nissen-Rosetti group in all categories of comparison. Return to normal eating habits was much earlier in the partial wrap group (p < 0.0001). Postop distal esophageal sphincter pressures in the two groups were equal at 15 mmHg. Eight patients suffered significant dysphagia requiring endoscopy and dilatation, all in the Nissen-Rosetti group (p < 0.01). Minor complications occurred in 12% of the total group. There was a total surgical revision rate of 3%. There were no gastric or esophageal perforations. Average operative time was 30 min. Average hospital stay was 1.4 days. Hospital charges for the laparoscopic approach averaged $6,000 dollars compared to $12,000 for the open approach. Conclusion: Laparoscopic partial fundoplication is as effective as laparoscopic Nissen-Rosetti fundoplication, with a higher satisfaction rate and fewer side effects. Measuring for wrap and hiatus size eliminates the need for and risk of using stiff dilators. By utilizing cosurgeons and currently available technology, cost, operative time, hospital time, and complications can be reduced to a finite minimum.

射频消融迷宫术治疗心房纤颤

作者采用射频消融迷宫术治疗心房纤颤２０例，其中１９例合并风湿性二尖瓣病的患者，同时行瓣膜替换术，１例合并房间隔缺损患者进行修复。射频消融的路线采用小板井嘉夫的手术径路。术后１６例恢复窦性心律，占８０％，未恢复窦性心律的４例，２例为房颤，１例为房扑，另１例为结性心律。射频消融迷宫术耗时短，仅增加钳闭主动脉时间平均２０．５分钟，无术后出血的潜在危险。但术后７～１０天之内，有１８例出现过房颤、房扑、房速等室上性心律失常，可能由于射频消融不均匀，干扰心房的心电活动所致。     

Ross procedure in an infant weighing 4.5 kg

A 6 month-old male infant (weight: 4.5 kg) with congenital aortic stenosis underwent aortic valve replacement with a pulmonary autograft (Ross procedure). The right ventricular outflow tract (RVOT) was reconstructed with a polytetrafluoroethylene (PTFE)-valved equine pericardial conduit. At the age of 5, re-RVOT reconstruction with an equine pericardial patch bearing a PTFE monocusp was required because of severe pulmonary stenosis resistant to 2 attempts of percutaneous transluminal pulmonary valvotomy. Currently, at the age of 8, the degree of aortic regurgitation is trivial and the pulmonary autograft is free of functional deterioration despite somatic growth.     

停跳或不停跳心脏手术对血清 S-100B蛋白表达的影响

【目的】研究心脏手术围术期血清S-100B蛋白表达及其与停跳或不停跳心肺转流方式和时间的关系。【方法】体外循环心脏手术患者23例,测转流前、转流10min、转流末、转流后24h的血清S-100B蛋白表达水平。【结果】①血清S-100B蛋白质量浓度在体外循环前后动态变化:转流前(M)为0.27μg/L,转流10min后升至0.57μg/L(P<0.01),转流末达峰值1.80μg/L(P<0.01),转流后24h降为0.22μg/L(P>0.05)。转流末的血清S-100B蛋白质量浓度与转流时间呈正相关(r=0.488,P<0.05)。②停跳组(n=6)转流前、转流10min、转流末、转流后24h平均血清S-100B蛋白质量浓度分别为(0.17±0.09)μg/L、(0.48±0.13)μg/L、(1.65±0.52)μg/L和(0.19±0.04)μg/L,不停跳组(n=6)分别为(0.26±0.14)μg/L、(0.71±0.41)μg/L、(1.59±0.84)μg/L和(0.23±0.11)μg/L,两组差别无统计学意义(P>0.05)。【结论】体外循环可导致血清S-100B蛋白表达增高,其表达水平与心肺转流时间呈正相关,但与停跳或不停跳转流方式无关。
