目的 探讨十二指肠良性肿瘤的诊断与治疗。方法 对1992~1998年间收治的10例患者的临床资料行回顾性总结分析。 结果术前经纤维十二指肠镜确诊7例 ，上消化道X线钡餐确诊3例。肿瘤位于十二指肠降部7例，球部3例。其中6例行手术治疗，4例因心肺脑等严重合并症行保守治疗。手术为十二指肠肿瘤局部切除连同周围肠壁组织部分切除。术后病理报告2例为平滑肌瘤，2例为布鲁氏纳氏腺瘤，2例为间质瘤。结论 十二指肠良性肿瘤可引发严重并发症，如出血、腹痛、肠梗阻、穿孔等，并约有15%的病例可发生恶变。一经诊断，应及早手术治疗，手术一般宜行局部切除。
Our clinical experiences in reconstruction of the defects from excision of benign tumors with expanded skin flap were reported. Since 1987 we have applied this method 23 cases with satisfactory results. When we decided to use this technique, the expander was placed in a pocket adjacent to a benign tumor planned to be excised. Once the skin flap was expanded fully, the tissue expanders were removed. After excision of the benign tumor, the defect was than be covered with the expanded skin flap. The problems related to treatment were discussed in detail.
目的 探讨十二指肠良性肿瘤的手术治疗方式及术后早期营养管理的效果。方法 回顾性分析2009年1月至2011年12月期间我科收治的15例十二指肠良性肿瘤患者的临床资料，根据肿瘤的生长部位及肿瘤大小实施不同的手术方式，术后早期给予肠内营养治疗及消化液回输，观察术后患者并发症发生率及术后2个月内的返院情况。结果 15例患者中2例患者肿瘤位于十二指肠乳头下、直径2.5cm和2.0cm，2例位于降部与水平部交界处、直径2.3cm和2.5cm，1例位于十二指肠升部、直径3.5cm，该5例患者行十二指肠节段切除并空肠吻合术。4例患者肿瘤位于十二指肠乳头、直径1.0～2.0cm，3例位于乳头上缘、直径1.5～1.8cm，2例位于球部与降部交界处、直径2.0cm和1.8cm，1例位于十二指肠乳头下、直径1.2cm，该10例患者均行肿瘤局部切除术（位于乳头部的肿瘤同时行乳头成形术）。围手术期无死亡病例。1例（1/15）发生胃排空障碍，经禁食、减压及营养支持治愈出院。术后住院时间为7～10d，平均8d。术后2个月患者均接受随访，恢复良好，无返院患者。结论 手术切除是十二指肠良性肿瘤的首选治疗手段，手术方式取决于肿瘤的生长部位和大小，术后早期营养管理安全、有效。
目的 分析肝脏良性肿瘤的临床诊断、治疗及治疗效果。方法 对川北医学院附属医院2008年2月至2011年2月期间收治并经术后病理学检查证实为肝脏良性肿瘤的156例患者的临床资料进行回顾性分析。结果 156例患者中肝血管瘤119例，肝细胞腺瘤13例，肝内胆管囊腺瘤3例，肝局灶结节性增生9例，肝淋巴管瘤4例，肝血管平滑肌脂肪瘤3例，肝炎性假瘤5例。3例肝局灶结节性增生患者行保守治疗，随访1年，其肿瘤大小和肝功能均无明显变化； 余153例患者行手术治疗，全部切除了病灶，病灶切除率为100％，术后随访6～48个月，平均24个月，均无死亡及复发。结论 肝脏良性肿瘤的症状不典型，缺乏特异性表现，易误诊，应完善超声、CT及MRI检查，并结合病史进行综合分析。对于具有临床症状、肿瘤体积较大（肿瘤直径＞5cm）的肝脏良性肿瘤患者，应积极行手术治疗，术后密切随访。
ObjectiveTo explore the surgical technique and clinical effect of endoscopic assisted transaxillary breast tumor resection in the treatment of benign and malignant breast tumors. MethodsThe clinical data of 18 patients received endoscopic breast tumor resection from September 2020 to December 2021 in the Department of Breast Surgery, West China Hospital, Sichuan University, were retrospectively analyzed to evaluate the feasibility, tumor safety and postoperative cosmetic effect. There were 7 patients with benign breast tumors (a benign breast tumor group) and 11 patients with early breast cancer (a malignant breast tumor group). Breast-Q and Scar-Q questionnaires were used to evaluate postoperative quality of life and satisfaction of patients. ResultsEndoscopic breast tumor resection was performed successfully in 18 female patients, among whom 12 patients received day surgery. The mean age of benign and malignant breast tumor groups was 29.6±11.6 years and 46.7±14.3 years, the mean tumor size in pathological examination was 3.3±2.1 cm and 2.0±0.8 cm, and the operative time was 138.9±57.0 min and 177.3±46.3 min, respectively. One patient had positive resection margin and underwent intraoperative extended resection in the malignant breast tumor group. All the patients were successfully followed up, and the mean follow-up time of benign and malignant breast tumor groups was 6.8±4.0 months and 8.7±4.9 months, respectively. No complications or tumor recurrence occurred. The scores of psychosocial status, sexual well-being, chest wall status and breast satisfaction decreased one month after surgery and basically recovered to the preoperative level in one year, and the score of scar appearance increased to 64.6±5.9 points one year postoperatively. ConclusionEndoscopic assisted transaxillary breast tumor resection can effectively improve postoperative cosmetic effect and patient satisfaction on the premise of safety.
ObjectiveTo explore the advantages and disadvantages of duodenum-preserving pancreatic head resection (DPPHR) in the clinical application of pancreatic surgical diseases, and to summarize the progress of minimally invasive application of DPPHR combined with the current application of laparoscopy and robot surgery in pancreatic surgery. MethodThe related research literatures about DPPHR at home and abroad in recent years were searched and reviewed. ResultsThe effect of DPPHR compared with traditional pancreaticoduodenectomy (PD) for treatment of benign pancreatic diseases was still controversial, and the postoperative remission effect, perioperative period, occurrence of long-term complications and improvement of quality of life were not very advantageous compared with PD, and the prognosis of minimally invasive surgery was poor. ConclusionDPPHR remains highly controversial for surgical intervention in benign pancreatic disease and has enormous scope for advances in minimally invasive surgical applications in pancreatic surgery, but more clinical studies are needed to verify its clinical efficacy.
ObjectiveThyroid nodules are an exceptionally common thyroid disorder. Past studies suggested a possible link between thyroid diseases and breast neoplasms. However, few studies have delved into the causal relationship between thyroid nodules and breast neoplasms. This study conducted a Mendelian randomization (MR) analysis to further investigate the causal relationship between them. MethodsThis study was conducted using data sourced from genome-wide association study (GWAS) summary datasets. The study focused on thyroid nodules, benign breast tumors, and malignant breast cancers as the research objects, and relevant single nucleotide polymorphisms (SNPs) were selected as instrumental variables (IVs). The inverse-variance weighted (IVW) was primarily used to assess the causal relationship between thyroid nodules and breast neoplasms. Cochran’s Q test was employed to detect heterogeneity, while MR-Egger intercept and MR-PRESSO were used to test for pleiotropy. Sensitivity analysis was conducted using the leave-one-out method. ResultsThere was a significant causal relationship between thyroid nodules and malignant neoplasm of breast (OR=0.88, 95%CI 0.83 to 0.95, P<0.01), with no evidence of reverse causality between them (OR=1.01, 95%CI 0.99 to 1.03, P=0.16). No causal relationship was found between thyroid nodules and benign neoplasm of breast, as indicated by both forward MR analysis (OR=0.97, 95%CI 0.89 to 1.06, P=0.51) and reverse MR analysis (OR=0.97, 95%CI 0.92 to 1.04, P=0.40). Sensitivity analyses suggested that the study findings were accurate and reliable. ConclusionThe present study identifies thyroid nodules as a potential protective factor for malignant neoplasm of breast.
From 1976 to 1991, 34 cases of benign tumors of femoral neck were received in our department and 29 cases were treated surgically with either free bone graft (18 cases) or vascularized bone graft (11 cases). Fibrous dysplasia of bone and bone cyst had a high incidence in this group (75%)and most of the patients were over 30 years old. Because the femoral neck had its own anatomical characteristics and was biomechanically important and in order to accelerate. The graft healing and prevent the occurrence of pathological fracture, the choice of operations should depend on the extent of the lesion, the thickness of the cortical bone of the affected past,and the presence or absence of complications.
Objective To study the clinical and CT findings of bronchiolar adenoma. Methods Patients diagnosed with bronchiolar adenoma confirmed by surgical pathology at Linyi People's Hospital and Yantai Yuhuangding Hospital from 2016 to 2021 were collected. Their clinical and CT imaging features were retrospectively analyzed. ResultsFinally, 25 patients were collected, including 6 males and 19 females, aged 32-73 (58.6±10.1) years. The immunohistochemical Ki-67 (MIB1) of all lesions was <5%. The lesions were located in the upper and middle lobe of both lungs in 9 patients, lower lobes in 16 patients, extrapulmonary zone in 22 patients, intrapulmonary middle zone in 3 patients, round in 11 patients, irregular in 14 patients, well-defined in 22 patients, pure ground-glass/mixed ground-glass nodules in 6 patients, solid nodules in 19 patients. There were 11 patients with central small cavity, 18 patients with single bronchioles sign, 19 patients without adhesion with adjacent pleura, and 24 patients without mediastinal lymph node enlargement. ConclusionBronchiolar adenomas usually occur in the middle-aged and elderly, mostly in the lower lobe of both lungs and the distribution of the peripheral lung field, most of the patients do not have any clinical symptoms, and the postoperative prognosis is good. CT may show large nodules or masses, pure ground-glass/mixed ground-glass nodules, irregular solid nodules and central small cavities. Irregular stellate nodules, central small cavity shadow, and single bronchiolar vascular bundle connected with the lesions are relatively specific imaging findings of bronchiolar adenoma.
