A prospective outcome analysis was conducted on 100 consecutive women who requested explantation of their silicone gel breast implants from January 6, 1992 (the moratorium), through 1995. Eighteen patients were referred by rheumatologists with a diagnosis of autoimmune or rheumatic disease. Six had autoimmune disease (systemic lupus, 2 patients; rheumatoid arthritis, 2 patients; multiple sclerosis, 1 patient; and Raynaud's disease, 1 patient). Twelve had rheumatic disease (fibromyalgia, 10 patients; inflammatory arthritis, 2 patients). All of these 18 patients had developed symptoms of their disease after they had received implants. All 100 patients were extensively evaluated pre- and postoperatively by interviews, clinical assessment, and by assay of the following laboratory tests: rheumatoid factor, ESR, ANA, and anti-Ro/SSA, -La/SSP, -Sm, -RNP, -double-stranded deoxyribonucleic acid, -Scl-70, -centromere, and -cardiolipin. Patients were also evaluated by a questionnaire that was sent at a mean time of 2.7 years postexplantation (range, 1-5 years), which had a 75% response rate. Reasons for implants were augmentation, 75%; lifting, 11%; reconstruction, 12%; and congenital aplasia, 2%. The mean age at first implant was 28.9 years (range, 13-55 years) and at explantation was 41.5 years (range, 25-65 years). The mean duration of implantation was 12.0 years (range, 1-27 years). Thirty-six percent of the patients had undergone at least one closed capsulotomy and 54% at least one open capsulotomy. The mean reasons for explantation were suspected silicone-related health problems, 76%; suspected rupture, 59%; breast firmness, 36%; breast pain, 36%; and musculoskeletal pain, 23%. Before explantation 75% of the questionnaire respondees had lost some sensitivity in their nipples following their breast augmentation. In 36% of those 75 patients, that loss was almost complete. Loss of sensitivity was related to capsular contracture and to pain (p < 0.05). Following explantation there was significant improvement in nipple sensitivity in 38% of breasts in the 75 respondees. A total of 186 implants were removed. Fifty-seven percent had failed by rupturing or leaking. Only 3.2% demonstrated extravasation extracapsularly. Twenty-five percent of the capsules were calcified, demonstrating visible plaques of calcification on their inner surface. Forty-two percent were colonized by bacteria. The prevalence of class III-IV capsular contracture was 61% and it was related to implant location, duration in situ, and capsular calcification (p < 0.05), but not to capsular colonization or implant integrity (p > 0.05). Only 43 of the 100 patients elected to have saline implants inserted. Of the others, 56% felt that the shell of the saline implant could be associated with medical problems. The others felt that breast size was of minor importance to them at this time. There were few complications from the explantation procedure. Two "masses" were discovered-one was an occult carcinoma, the other a galactocele. There was one wound infection, which responded to antibiotics. Three patients developed decreased sensitivity and 3 developed increased breast pain. From the patient questionnaires, in those women who did not have saline implants inserted, 15% felt that their breast appearance was improved after explantation, 36% were "pleased," 33% were disappointed, and 13% felt "mutilated". In women who did have saline implants inserted, 18% felt that their breast appearance was now improved, 60% were "pleased," and 14% were disappointed, mainly because of wrinkling. At a mean time of 2.7 years (range, 1-5 years) after explantation, 45% of the 75 questionnaire respondees felt that their implants had caused permanent health problems and 56% felt that they had not been given adequate informed consent by their original surgeon (particularly regarding implant rupture and a possible relationship to medical disease).

对1992年1月6日(禁令生效日)至1995年期间连续100名要求取出硅胶乳房植入物的女性进行了前瞻性结果分析。18名患者由风湿病学家转诊,诊断为自身免疫性或风湿性疾病。其中6名患有自身免疫性疾病(系统性红斑狼疮2例;类风湿性关节炎2例;多发性硬化症1例;雷诺氏病1例)。12名患有风湿性疾病(纤维肌痛10例;炎症性关节炎2例)。这18名患者在植入假体后均出现了疾病症状。所有100名患者在术前和术后均通过访谈、临床评估以及以下实验室检查进行了全面评估:类风湿因子、红细胞沉降率、抗核抗体以及抗Ro/SSA、-La/SSP、-Sm、-RNP、双链脱氧核糖核酸、-Scl-70、着丝粒和心磷脂抗体检测。患者还在植入物取出后平均2.7年(范围1 - 5年)时通过问卷调查进行了评估,问卷回复率为75%。植入假体的原因如下:隆胸占75%;提升占11%;重建占12%;先天性发育不全占2%。首次植入时的平均年龄为28.9岁(范围13 - 55岁),取出时的平均年龄为41.5岁(范围25 - 65岁)。植入的平均时长为12.0年(范围1 - 27年)。36%的患者至少接受过一次闭合性包膜切开术,54%的患者至少接受过一次开放性包膜切开术。取出假体的主要原因如下:怀疑与硅胶相关的健康问题占76%;怀疑破裂占59%;乳房变硬占36%;乳房疼痛占36%;肌肉骨骼疼痛占23%。在取出假体前,75%的问卷受访者在隆胸后乳头出现了一定程度的感觉丧失。在这75名患者中,36%的人几乎完全丧失了乳头感觉。感觉丧失与包膜挛缩和疼痛相关(p < 0.05)。在75名问卷受访者中,38%的乳房在取出假体后乳头感觉有显著改善。共取出186个植入物。57%的植入物因破裂或渗漏而失效。仅有3.2%的植入物出现了囊外渗漏。25%的包膜出现钙化,在其内表面可见钙化斑块。42%的包膜有细菌定植。III - IV级包膜挛缩的发生率为61%,与植入位置、在位时长和包膜钙化相关(p < 0.05),但与包膜细菌定植或植入物完整性无关(p > 0.05)。100名患者中只有43人选择植入生理盐水假体。其余患者中,56%认为生理盐水假体的外壳可能会引发医疗问题。其他人则认为此时乳房大小对她们来说不太重要。取出假体的手术并发症较少。发现了两个“肿块”——一个是隐匿性癌,另一个是乳腺囊肿。发生了1例伤口感染,使用抗生素后好转。3名患者出现感觉减退,3名患者乳房疼痛加重。从患者问卷来看,在未植入生理盐水假体的女性中,15%认为取出假体后乳房外观有所改善,36%“满意”,33%感到失望,13%觉得“被毁容”。在植入了生理盐水假体的女性中,18%认为现在乳房外观有所改善,60%“满意”,14%感到失望,主要是因为假体起皱。在取出假体后平均2.7年(范围1 - 5年)时,75名问卷受访者中有45%认为她们的假体导致了永久性健康问题,56%认为她们当初的外科医生没有给予充分的知情同意(特别是关于假体破裂以及与疾病可能的关系)。(摘要截选)
