完全性胸腹腔内脏反位合并十二指肠壶腹周围癌一例报告与文献复习

目的总结完全性胸腹腔内脏反位合并十二指肠壶腹周围癌的临床诊治方法。方法报道2006年3月收治的1例极为罕见的完全性胸腹腔内脏反位合并十二指肠壶腹周围癌行胰十二指肠切除术的病例,并复习国内外相关文献。结果本例患者病理诊断为十二指肠乳头及壶腹部腺癌Ⅰ-Ⅱ级。术后1周胆红素降至正常;但2周后出现胃-空肠吻合输出袢粘连性不完全性梗阻,经内镜下置管、鼻饲、营养支持、针灸等处理,40d后痊愈出院。经检索,全球自1936-2006年间报道的全胸腹腔内脏反位合并恶性肿瘤的患者仅15例;其中只有5例全胸腹腔内脏反位合并胰头与壶腹周围癌的报道。结论完全性胸腹腔内脏反位合并肿瘤时,若无明显禁忌证,应同样予以积极的外科治疗,术中操作应注意完全相反的解剖学结构。

Gall Bladder Carcinoma with Ampullary Carcinoma: A Rare Case of Double Malignancy

Simultaneous double cancers in the biliary system are rare. Most are associated with pancreaticobiliary maljunction (PBM). However, it can occur in patients without PBM. Differentiation between these events is important since these two mechanistic origins imply different stages of disease, as well as different subsequent treatments and prognoses. Herein, we report a case of ampullary carcinoma associated with gall bladder carcinoma diagnosed nonoperatively and palliated with biliary metal stenting.     

Unforeseen encounter of acquired hemophilia A in a preoperative case of periampullary carcinoma: A case report

IntroductionAcquired hemophilia A (AHA) is a rare disorder characterized by development of antibodies against factor VIII, which can present as paraneoplastic syndrome in various malignancies like periampullary cancer, cancer of lung, prostate, gastrointestinal stromal tumour and non malignant cases like pregnancy, autoimmune disease and medication.Case presentationWe report a case of elderly man presented with paraneoplastic AHA in periampullary carcinoma in preoperative period which was diagnose by mixing study and inhibitor assay and managed with bypass agents like recombinant factor VII, FEIBA and immunosuppresion to eliminate inhibitor with help of steroid, cyclophosphamide and emicizumab. Patient underwent Whipple’s pancreaticoduodenectomy after which coagulation study became normal in immediate postoperative period. Patient was discharged and followed up with chemotherapy.Clinical discussionPeriampullary carcinoma presenting as AHA is rare and rarer in pre-operative settings. The usual mode of presentation is bleeding after biopsy and from minor surgical scars. The pathogenesis is yet to be delineated. It is managed by factor VIII administration and immunosuppressive therapy.ConclusionHigh index suspicion should be there to diagnose AHA as a paraneoplastic manifestation and elective surgery should be delayed till normalization of coagulation parameters.     

完全腹腔镜下与开腹胰十二指肠切除术治疗壶腹周围肿瘤近期疗效比较

目的探讨完全腹腔镜下胰十二指肠切除术(TLPD)与开腹胰十二指肠切除术(OPD)治疗壶腹周围肿瘤的近期疗效。方法回顾性分析山西医科大学第一医院2016年6月至2019年3月收治的50例壶腹周围肿瘤患者的临床资料,根据手术方式不同分为TLPD组(22例)及OPD组(28例),比较两组患者围术期及术后各项指标情况。结果两组患者均顺利完成手术,TLPD组手术时间[(665±213)min]长于OPD组[(447±215)min],差异有统计学意义(t=-0.356,P=0.001);TLPD组术中出血量[100 ml(50~325 ml)]少于OPD组[300 ml(100~500 ml)],差异有统计学意义(Z=-2.230,P=0.026)。TLPD组与OPD组术中输血者比例、淋巴结清扫数量、切除肿瘤长径、术后禁饮食时间、术后拔管时间、术后住院时间及术后并发症发生率比较,差异均无统计学意义(均P>0.05)。结论TLPD与OPD治疗壶腹周围肿瘤临床近期疗效相近,TLPD手术时间较OPD长,但可有效控制术中出血量。     

MicroRNA profiling in periampullary carcinoma

BackgroundMicroRNA expression patterns in many physiological and oncogenic processes have been established. However, the role of aberrant miRNA expression in periampullary carcinoma (PAC) has not been elucidated. We hypothesize that PAC may have differential expression of miRNAs which may differentiate the tumor histological subtypes.MethodsFresh paired tumor and control samples were collected from the PAC patients undergoing Whipple's pancreaticoduodenectomy. Microarray miRNA profiling was performed utilizing tumor (n = 40) and control tissues; adjacent normal pancreas (n = 22), six each distal CBD, duodenum and ampulla. Data obtained was subjected to statistical and bioinformatic analysis. Differentially expressed miRNAs obtained were validated using qPCR in an independent set of samples.ResultsComparison of PAC tissue samples with controls revealed 29 common and differentially expressed miRNAs (20 upregulated and 9 downregulated) with a higher statistical significance (p < 0.001) and fold change (log2 FC > 1.5). A subset of 16 miRNAs (15 overexpressed and 1 underexpressed) differed in expression levels between pancreatobiliary and intestinal subtypes. Among these, miR-375, miR-31 and miR-196a expressions varied significantly between histological subtypes. Differential expression profiles of miRNAs specific to TNM staging was also observed in PAC subtypes. Target gene prediction for the differentially expressed miRNAs in PAC revealed that target genes are enriched for certain pathways. Particularly, Wnt signaling pathway genes appear to be relevant targets for most of the differentially expressed miRNAs.ConclusionDifferentially expressed common miRNA signatures identified in PAC subgroups may have a role in pathogenesis of PAC and miR-375, miR-31 and miR-196a expression patterns may differentiate PAC subtypes.
