    近年来,由于医疗不当投诉的增加,西西里地区卫生系统采用了直接管理每个医疗机构索赔的程序,目的是降低保险费和相关税收的成本。强制性哨点事件监测是该策略的关键部分,以提高患者安全和护理质量。报道的病例涉及通过碎裂术进行的腹腔镜子宫肌瘤切除术,有争议的技术。在2014年FDA的干预之后,人们认为分碎术可能会通过将平滑肌肉瘤等恶性肿瘤扩散到腹部来恶化疾病的分期。
    一个28岁的女人,2018年8月接受了腹腔镜子宫肌瘤手术和卵巢囊肿切除术.手术后,她被诊断患有平滑肌瘤.她因出血而返回医院,一周后出院。持续的症状导致她再次入院,随后在另一家医院进行了腹腔镜探查手术。这导致了全子宫切除术和子宫平滑肌肉瘤的发现,与FIGO阶段IIIB分期。尽管化疗,六个月后她去世了。
    这个案例突出了医疗法律问题。未获得分乳及其风险的知情同意。使用了分块技术,增加癌症扩散的风险。组织病理学过程不充分,三次活检导致误诊。这可能是医疗事故,使提供者对患者病情恶化和可能死亡的预期负法律责任。
    UNASSIGNED: In recent years, due to the increase in medical mal-practice complaints, the Sicilian Regional Health System has adopted procedures for the direct management of claims by each health facility with the aim of reducing the costs of insurance premiums and related taxes. Mandatory sentinel event monitoring is a crucial part of this strategy to improve patient safety and quality of care. The reported case relates to a laparoscopic myomectomy surgery performed by means of morcellation, a controversial technique. After the FDA\'s intervention in 2014, it is believed that morcellation may worsen the staging of the disease by spreading malignancies such as leiomyosarcoma into the abdomen.
    UNASSIGNED: A 28-year-old woman, underwent laparoscopic surgery for uterine fibroids and an ovarian cyst removal in August 2018. Post-surgery, she was diagnosed with Leiomyoma. She returned to the hospital due to metrorrhagia and was discharged after a week. Persistent symptoms led to her readmission and subsequent exploratory laparoscopic surgery at another hospital. This resulted in a total hysterectomy and the discovery of uterine leiomyosarcoma, with FIGO STAGE IIIB staging. Despite chemotherapy, she passed away six months later.
    UNASSIGNED: This case highlights medical-legal issues. Informed consent for morcellation and its risks was not obtained. The morcellation technique was used, increasing cancer spread risk. The histopathological process was inadequate, with three biopsies leading to misdiagnosis. This could be medical malpractice, making providers legally responsible for the patient\'s deteriorating condition and the anticipation of possible death.

    背景:膀胱癌患者在根治性膀胱切除术(RC)前使用双J支架(DJ)是否会增加上尿路肿瘤种植的风险,从而增加异时性上尿路上皮癌(UTUC)的风险,这是有争议的。我们研究的目的是调查先前使用DJ支架治疗的患者在RC后上尿路复发的风险。
    方法:我们的研究纳入了在2003年1月至2022年3月期间接受RC的699例患者,这些患者具有完整的围手术期数据和病理结果。确定了术前接受DJ支架治疗的患者,并将其与先前未接受内部支架置入的患者进行了异时UTUC的发展进行了比较。多变量Cox回归分析用于确定可能的病理特征中UTUC发生的预测因子;还检查了RC后死亡的危险因素。
    结果:在699名患者中,117(16.7%)术前使用DJ支架进行管理。异时UTUC的总概率为1%,在1年、3年和5年分别为4%和6%,分别。在临床病理特征方面,有和没有DJ支架的组具有可比性,DJ组肾积水发生率较高。在相似的随访期间(中位随访32个月),在DJ组4例(3.4%)患者和非支架组13例(2.2%)患者中检测到异时UTUC(P=0.44).DJ组从膀胱切除术到UTUC的中位间隔(IQR)为40.5(20-49)个月,非支架组为37(24-82)个月(P=0.7)。在多变量分析中,仅CIS(HR3.83,95%CI1.19-12.29,P=0.024)和输尿管边缘阳性(HR=5.2,95%CI1.38-19.57,P=0.015)是异时UTUC的预测因子.该研究受到回顾性性质和相对较短随访的限制。
    结论:输尿管支架置入术治疗膀胱癌患者肾积水是可行的选择,没有更高的UTUC风险或死亡率。输尿管切缘阳性和CIS的患者被认为是上尿路复发的高危人群,应接受长期治疗,严格的跟进。
    BACKGROUND: It is controversial whether the use of a double-J stent (DJ) in patients with bladder cancer before radical cystectomy (RC) increases the risk of tumour seeding in the upper tract and thus the risk of metachronous upper tract urothelial carcinoma (UTUC). The aim of our study is to investigate the risk of upper tract recurrence after RC in patients previously managed with a DJ stent.
    METHODS: A total of 699 patients who had undergone RC between January 2003 and March 2022 with complete perioperative data and pathological outcome were included in our study. Patients treated preoperatively with a DJ stent were identified and compared for development of metachronous UTUC with those who did not receive prior internal stenting. Multivariable Cox regression analysis was used to determine predictors of UTUC occurrence among the possible pathological features; risk factors for mortality after RC were also examined.
    RESULTS: Of 699 patients, 117 (16.7%) were managed preoperatively with a DJ stent. The overall probability of metachronous UTUC was 1%, 4% and 6% at 1, 3 and 5 years, respectively. The groups with and without DJ stenting were comparable regarding their clinicopathologic features, except for the higher incidence of hydronephrosis in the DJ group. At similar follow-up periods (median follow-up 32 months), metachronous UTUC was detected in four (3.4%) patients in the DJ group and in 13 (2.2%) in the non-stented group (P=0.44). The median interval (IQR) from cystectomy to UTUC was 40.5 (20-49) months in the DJ group and 37 (24-82) in the non-stented group (P=0.7). In the multivariable analysis, only presence of CIS (HR 3.83, 95% CI 1.19-12.29, P=0.024) and positive ureteral margin (HR=5.2, 95% CI 1.38-19.57, P=0.015) were predictors of metachronous UTUC. The study is limited by the retrospective nature and relatively short follow-up.
    CONCLUSIONS: Ureteral stenting for management of hydronephrosis in patients with bladder cancer undergoing RC is a viable option, without higher risk for UTUC or mortality. Patients with positive ureteral margin and CIS are considered high-risk groups for upper tract recurrence and should receive long-term, rigorous follow-up.

    玻璃体内化疗期间视网膜母细胞瘤玻璃体种子(VS)的消退可以延迟,导致多余的注射。同样,最初,VS复发可能在临床上并不明显。肿瘤消退和复发的预测生物标志物可以帮助指导实时临床决策。视网膜母细胞瘤是一种氧敏感肿瘤;矛盾的是,VS在缺氧玻璃体中存活。我们假设VS精心制作了促血管生成细胞因子。目的是确定来自房水的促血管生成细胞因子特征是否可以用作VS对治疗的反应的生物标志物。
    对来自具有人视网膜母细胞瘤VS异种移植物的兔眼的房水进行多重ELISA,以鉴定表达的促血管生成细胞因子,并确定在玻璃体内治疗期间房水细胞因子水平的变化。在人视网膜母细胞瘤肿瘤切片和兔VS异种移植物上进行了VEGF-A的验证性RNAscope原位杂交。对于接受玻璃体内化疗的人眼,通过VEGF-A特异性ELISA测量的系列水性VEGF-A水平与临床反应进行比较。
    VEGF-A在人视网膜母细胞瘤VS异种移植模型中高表达,并且是唯一与VS疾病负荷相关的促血管生成细胞因子。在兔子中,水性VEGF-A水平降低对治疗的反应,与定量VS减少一致。在患者中,与疾病负担临床变化相关的水性VEGF-A水平(回归,稳定性,或复发),VEGF-A水平的变化与临床反应相关。
    水性VEGF-A水平与视网膜母细胞瘤VS的程度相关,提示水性VEGF-A可作为治疗反应的预测分子生物标志物。
    UNASSIGNED: Regression of retinoblastoma vitreous seeds (VS) during intravitreal chemotherapy can be delayed, resulting in supernumerary injections. Similarly, VS relapse may not be clinically evident at first. A predictive biomarker of tumor regression and relapse could help guide real-time clinical decision making. Retinoblastoma is an oxygen-sensitive tumor; paradoxically, VS survive in the hypoxic vitreous. We hypothesized that VS elaborate pro-angiogenic cytokines. The purpose was to determine if pro-angiogenic cytokine signatures from aqueous humor could serve as a biomarker of VS response to treatment.
    UNASSIGNED: Multiplex ELISA was performed on aqueous from rabbit eyes with human retinoblastoma VS xenografts to identify expressed proangiogenic cytokines and changes in aqueous cytokine levels during intravitreal treatment were determined. Confirmatory RNAscope in situ hybridization for VEGF-A was performed on human retinoblastoma tumor sections and VS xenografts from rabbits. For human eyes undergoing intravitreal chemotherapy, serial aqueous VEGF-A levels measured via VEGF-A-specific ELISA were compared to clinical response.
    UNASSIGNED: VEGF-A was highly expressed in human retinoblastoma VS in the xenograft model, and was the only proangiogenic cytokine that correlated with VS disease burden. In rabbits, aqueous VEGF-A levels decreased in response to therapy, consistent with quantitative VS reduction. In patients, aqueous VEGF-A levels associated with clinical changes in disease burden (regression, stability, or relapse), with changes in VEGF-A levels correlating with clinical response.
    UNASSIGNED: Aqueous VEGF-A levels correlate with extent of retinoblastoma VS, suggesting that aqueous VEGF-A may serve as a predictive molecular biomarker of treatment response.

    背景:偶发胆囊癌是指在胆囊切除术期间或之后发现的胆囊癌。腹腔镜胆囊切除术(LC)后的晚期端口部位转移(PSM)很少见,发生率为10.3%。
    方法:我们报告一例58岁的男性,表现为腹壁肿块疼痛6周。他有症状性胆石症的LC病史,8年前
    方法:组织病理学检查显示腹壁肿块的转移性腺癌阳性结果。此外,正电子发射断层扫描(PET)显示胆囊床中少量的氟脱氧葡萄糖(FDG)摄取,这是高度可疑的恶性肿瘤。
    方法:由于胆囊床上的摄取,决定进行手术,并向先前的端口部位转移。此外,在董事会会议上,根据在全转移检查中发现的结果,由于恶性肿瘤的不确定性,我们就进行远端胰腺切除术和脾切除术达成了协议.诊断性腹腔镜检查,然后进行中线剖腹手术。行根治性完整胆囊切除术伴淋巴结清扫术。随后完整切除前腹壁。然后进行胰体切除术和脾切除术。
    结果:病理诊断显示转移性/侵袭性,中分化腺癌,切除的端口部位肿块后表面切缘阳性。阳性边缘需要进一步的放化疗,随后进行辅助化疗,直至发现肺转移。在这之后,患者计划接受姑息性化疗.
    结论:PSM的存在通常与腹膜转移有关。出于这个原因,建议评估患者是否有转移。
    BACKGROUND: Incidental gallbladder carcinoma refers to a discovery of gallbladder cancer during or after cholecystectomy. Late port-site metastasis (PSM) following Laparoscopic cholecystectomy (LC) is rare with an incidence rate of 10.3%.
    METHODS: We report a case of a 58-year-old man who presented with a painful abdominal wall mass for 6 weeks. He had a history of LC for symptomatic cholelithiasis, 8 years prior.
    METHODS: Histopathological examination revealed a positive result for metastatic adenocarcinoma from the abdominal wall mass. Moreover, Positron emission tomography (PET) showed a small focus of intense fluorodeoxyglucose (FDG) uptake in the gallbladder bed, which was highly suspicious for malignancy.
    METHODS: Decision was to proceed with surgery owing to uptake in the gallbladder bed with single-site metastasis to the previous port site. In addition, in the board meeting, an agreement was reached for performing distal pancreatectomy with splenectomy owing to uncertainty of malignancy based on what was discovered during the full metastatic workup. Diagnostic laparoscopy followed by midline laparotomy performed. Radical completion cholecystectomy with lymphadenectomy was done. Followed by complete resection of the anterior abdominal wall. Distal pancreatectomy and splenectomy were then performed.
    RESULTS: Pathological diagnosis showed metastatic/invasive, moderately differentiated adenocarcinoma with positive margins on the posterior surface of excised port-site mass. The positive margins necessitated further chemoradiotherapy, followed by adjuvant chemotherapy until lung metastasis was identified. After this, the patient was scheduled for palliative chemotherapy.
    CONCLUSIONS: Presence of PSM is often associated with peritoneal metastasis. For this reason, it is advised to evaluate the patient for possible metastasis.

    癌症患者由于食物摄入减少而面临营养不良的风险,因此使口服摄入具有挑战性。因此,营养支持用于提供营养需求。据报道,在内窥镜喂养胃造口术安装后,癌症患者的喂养管部位植入。本手稿旨在使用结构化数据库审查进一步探讨这一现象。在这项审查中包括的33个播种案例中,病例报告(70%)是最常见的研究设计,主要采用经皮内镜胃造瘘术。植管至播种检测的时间为7.12±3.7个月,在纳入的研究中缺少一些数据。最常见的原发癌诊断为头颈部癌。男性患者的肿瘤种植率高于女性患者。然而,大规模,需要统计学支持的研究来进一步调查这种并发症.
    Patients with cancer are at risk of malnutrition because of reduced food intake, thus making oral intake challenging. Thus, nutritional support is used to provide the nutrient requirements. Feeding tube site implantation among patients with cancer has been reported after endoscopic feeding gastrostomy installation. This manuscript aims to further explore this phenomenon using a structured database review. Among 33 seeding cases included in this review, case reports (70 %) were the most common study design, predominantly using percutaneous endoscopic gastrostomy via the pull method. The duration between tube implantation and seeding detection ranged from 7.12 ± 3.7 months, with some missing data among the included studies. The most common primary cancer diagnosis was head and neck cancer. Tumor seeding was higher among male patients than that in female patients. However, large-scale, statistically powered studies are needed to further investigate this complication.

    背景:胰腺导管腺癌(PDAC)的EUS-FNA/B通常被认为是安全的;但是,虽然发病率很低,有并发症的发生。在这些并发症中,有严重的像针道播种(NTS),尚不清楚哪种类型的肿瘤有EUS-FNA/B并发症的风险。本研究旨在评估PDAC患者EUS-FNA/B并发症的风险。专注于形态特征。
    方法:总的来说,回顾性调查了2018年1月至2022年5月在四个机构中接受EUS-FNA/B治疗胰腺实性肿块的442例患者。最后,对361例经组织病理学诊断为PDAC的患者进行分析。在这些患者中,将79个具有囊肿或坏死成分的肿瘤与282个没有囊肿或坏死成分的肿瘤进行了比较。评估包括NTS在内的EUS-FNA/B并发症的发生率和风险。
    结果:共有9例(2.4%)EUS-FNA/B并发症和3例(0.8%)NTS。有囊肿或坏死成分的肿瘤的总并发症发生率和NTS的发生率明显高于无囊肿或坏死成分的肿瘤(总并发症6.3%vs.1.4%,p=0.026,NTS3.7%与0%,p=0.01)。经胃穿刺途径(OR:93.3,95%CI:3.81-2284.23)和囊肿或坏死成分的存在(OR:7.3,95%CI:1.47-36.19)是多变量分析确定的EUS-FNA/B并发症的危险因素。
    结论:我们应该注意EUS-FNA/B并发症的风险,包括NTS,当肿瘤有囊肿或坏死成分时。
    BACKGROUND: EUS-FNA/B for pancreatic ductal adenocarcinoma (PDAC) is generally considered to be safe; however, while the incidence is low, there are occurrences of complications. Among these complications, there are serious ones like needle tract seeding (NTS), and it is not known than which types of tumors have the risks of EUS-FNA/B complications. This study aimed to evaluate the risk of EUS-FNA/B complications in patients with PDAC, focusing on morphological features.
    METHODS: Overall, 442 patients who underwent EUS-FNA/B for solid pancreatic masses between January 2018 and May 2022 in four institutions were retrospectively surveyed. Finally, 361 patients histopathologically diagnosed with PDAC were analyzed. Among these patients, 79 tumors with cysts or necrotic components were compared with 282 tumors without cysts or necrotic components. The incidence and risk of EUS-FNA/B complications including NTS were evaluated.
    RESULTS: There were 9 (2.4 %) of total EUS-FNA/B complications and 3 (0.8 %) of NTS. The incidence of total complication rate and NTS in tumors with cysts or necrotic components were significantly higher than in those without cysts or necrotic components (total complication 6.3 % vs. 1.4 %, p = 0.026, NTS 3.7 % vs. 0 %, p = 0.01). The transgastric route of puncture (OR: 93.3, 95 % CI: 3.81-2284.23) and the existence of cysts or necrotic components (OR: 7.3, 95 % CI: 1.47-36.19) were risk factors for EUS-FNA/B complications identified by the multivariate analysis.
    CONCLUSIONS: We should pay attention to the risks of EUS-FNA/B complications, including NTS, when the tumor has cysts or necrotic components.
