Reoperation for a patient with starr-edwards aortic valve malfunction due to pannus formation twenty-nine years after implantation

We report a re-do case of severe aortic valve stenosis due to pannus formation 29 years after an aortic Starr-Edwards caged-ball valve implantation. A huge shelf of calcified and thick pannus tissue below the valve had reduced the already small orifice by at least a third in surface area. The explanted Starr-Edwards valve revealed no mechanical or structural failure. Early detection and treatment of pannus outgrowth is essential in order to prevent life-threatening prosthetic valve malfunctions.     

股骨干骨折内固定术后不愈合27例分析

报告股骨干骨折切开复位内固定术后不愈合27例。其中，17例钢板固定者，只4例符合要求，9例髓内针固定者，有5例针短小。尚伴有固定方法，钢板或髓内针断裂，以及感染等方面原因有。本组再手术26例1次手术治愈，1例2次手术治愈。绝大部分经带蒂骨皮质剥离^[1]和坚强内固定术后而愈合，不需植骨。产生骨折不愈合的诸因素中，以忽视内固定的基本原则与术中操作不当为主。     

分化型甲状腺癌术后颈淋巴结持续或复发治疗进展

颈淋巴结复发是分化型甲状腺癌复发中最主要的一部分,其治疗的主要方案为再手术治疗。近年来一些如主动监测、射频消融、放射性碘治疗等代替手术治疗的方案逐渐被提出。部分治疗手段的效果及并发症仍有争议,再手术仍是首选的治疗方式,再术后的放射性碘治疗可能不会改善病人的预后,射频消融应仅限应用于不适合再次手术治疗的病人。     

Revisional Surgery for Severe Obesity with Fascia Banded Stoma Roux-en-Y Gastric Bypass

The fascia banded stoma Roux-en-Y gastric bypass (RYGBP) has been effective both as a primary and revision operation for severe obesity or failure of another operation. Since May 1984, 361 primary and 100 revisional fascia banded RYGBP operations have been reported. Weight loss achieved a mean body mass index of 30 for primary and 31 for revision patients at most recent follow-up of 3-6 years (mean 4.3 years) postoperatively. Mean overweight was 28% for primary, and 34% for revision patients. Eighty percent of primary and 79% of revision patients were within 50% of ideal weight. Revision rates for these patients were 0 for primary and 1% for revision patients. Operative mortality was 0 for primary and 1% for revision patients. Since morbidity and mortality, although low, are higher for revision than primary surgery, it is important to use an effective primary operation.     

Erosion of Marlex Mesh Collar after Vertical Banded Gastroplasty

Marlex mesh, as opposed to silastic ring, when used as a collar in the bariatric procedure of vertical banded gastroplasty, has been reported rarely to erode into the gastric lumen. We report two cases of such an erosion, of which one ended as a complete internalization of the collar into the stomach. In one of the patients we observed a wider than expected portion of tissue that had been encircled by the collar, which might have caused a local inflammatory reaction leading to the later erosion.     

Modification of Gastric Banding,Using a Fundal Suture

Many forms of gastric banding have been described and high reoperation rates reported. These can be mainly attributed to excess vomiting associated both with and without stenosis. Reflux oesophagitis and the ‘sump’ effect may be other causes. This paper examines the problems associated with banding leading to revisional surgery and introduces a new technique, ‘fundal supporting suture’, to correct these problems. Preliminary results on 126 bandings without the modification and 22 with the modification are presented.     

甲状腺结节76例再次手术分析及治疗

目的 分析甲状腺结节再次手术的原因，要点和治疗的探讨。方法 回顾分析近7年来76例甲状腺结节再次手术的临床资料，并结合文献进行讨论。结果 无手术死亡，无喉返神经损伤，无需输血，术中气管痉挛4例，暂时性甲状腺功能低下13例，喉上神经损伤2例；56例获得8个月～7年随访，甲状腺结节治愈率100％，无甲状腺功能低下现象。结论 甲状腺结节术后复发再手术疗效确切，亦要重视手术要点，可预防或减少副损伤发生。     

胆总管下段医源性损伤后胆道再手术

目的探讨胆总管下段医源性损伤后不同的胆道再手术方法。方法回顾性分析重庆医科大学附属第一医院2005年6月至2015年9月收治的8例胆总管下段医源性损伤的临床资料。结果 8例中,2例采用胆总管局部修补,3例行Oddi括约肌切开成形,1例行胆管空肠Roux-en-Y吻合,1例直接行胰十二指肠切除,1例采用充分引流,术后均治愈出院,住院时间22~46 d,平均住院时间为31.5 d。结论根据损伤的具体部位、破口大小、合并症及发现时间的早晚,对不同病人采取个体化治疗;对胆总管下段损伤的预防及早期处理至关重要。
