Abstract

BACKGROUND:Venous thromboembolism (VTE) is one of the critical complications that can occur after surgery. A positive association between cancer and VTE risk is well established; however, the safety and efficacy of VTE prophylaxis have not been established in hepatobiliary-pancreatic surgery, especially in surgery for malignancies. METHODS:A prospective, multi-center Phase I study to determine the safety of enoxaparin was performed. Subcutaneous injection of enoxaparin was initiated 48-72 h after surgery and repeated for 8 days. The primary endpoint was the incidence of bleeding events. This study was registered with the University Hospital Medical Information Network Clinical Trials Registry (UMIN000007761). RESULTS:A total of 154 patients was registered and 133 patients including 74 hepatectomies and 35 pancreaticoduodenectomies were analyzed. Three patients (2.3%) exhibited major bleeding events postoperatively, while 7 (5.2%) had minor bleeding. No Symptomatic VTE was observed. CONCLUSIONS:Our study indicated that enoxaparin was well tolerated and safe for patients who received hepatobiliary-pancreatic surgery for malignancies.

摘要

背景: 静脉血栓栓塞症 (VTE) 是手术后可能发生的严重并发症之一。癌症和VTE风险之间的正相关已被确定; 然而,在肝胆胰手术中,特别是在恶性肿瘤手术中,VTE预防的安全性和有效性尚未确定。 方法: 进行了一项前瞻性、多中心I期研究,以确定依诺肝素的安全性。术后48-72 h开始皮下注射依诺肝素,重复8天。主要终点是出血事件的发生率。本研究在大学医院医学信息网临床试验注册中心 (UMIN000007761) 注册。 结果: 共登记了154例患者,分析了133例患者,包括74例肝切除术和35例胰十二指肠切除术。3例患者 (2.3%) 术后出现大出血事件,7例 (5.2%) 出现轻微出血。未观察到有症状的VTE。 结论: 我们的研究表明,对于接受肝胆胰手术治疗恶性肿瘤的患者,依诺肝素具有良好的耐受性和安全性。

METHODS:AIM:To investigate the value of contrast enhanced ultrasound with high resolution linear transducers (HF-CEUS) for differential diagnosis of focal fundal gallbladder (GB) wall thickening. METHODS:A total of 32 patients with incidentally detected focal fundal GB wall thickening were included. After conventional B mode ultrasound (BMUS) examinations, HF-CEUS were performed with a 7.5-12 MHz 9L4 linear transducer (S2000 HELX OXANA unit, Siemens). Two radiologists independently reviewed the HF-CEUS enhancement patterns to determine the differential features between malignancy and benignity with a five-point confidence scale. The diagnostic accuracy of BMUS and HF-CEUS for GB wall thickening was compared. The final gold standard was surgery with histological examination. RESULTS:Final diagnoses included GB adenocarcinoma (n = 16), adenomyomatosis (n = 12), Xanthogranulomatous (n = 2) and cholecystitis (n = 2). HF-CEUS features associated with GB adenocarcinoma including arterial phase inhomogeneous hyperenhancement, venous phase hypoenhancement and disruption of GB wall layer structure (P < 0.05). Two small (5 mm) liver metastasis were confirmed by HF-CEUS during the late phase liver sweep as hypoenhanced lesions. Nonenhanced Rokitansky-Aschoff sinuses were clearly observed in 83.3% focal adenomyomatosis. Overall sensitivity, specificity and accuracy for differentiation between malignant and benign focal fundal GB wall thickening of HF-CEUS and BMUS were 84.3% vs 53.1%, 90.6% vs 59.3% and 87.5% vs 56.2% (P < 0.005). CONCLUSIONS:CEUS performed with high frequency linear transducers could be a useful alternative in the differential diagnosis of focal fundal GB wall thickening on conventional ultrasound.

METHODS::Small-for-size graft (SFSG) syndrome after living donor liver transplantation (LDLT) is the dysfunction of a small graft, characterized by coagulopathy, cholestasis, ascites, and encephalopathy. It is a serious complication of LDLT and usually triggered by excessive portal flow transmitted to the allograft in the postperfusion setting, resulting in sinusoidal congestion and hemorrhage. Portal overflow injures the liver directly through nutrient excess, endothelial activation, and sinusoidal shear stress, and indirectly through arterial vasoconstriction. These conditions may be attenuated with portal flow modulation. Attempts have been made to control excessive portal flow to the SFSG, including simultaneous splenectomy, splenic artery ligation, hemi-portocaval shunt, and pharmacological manipulation, with positive outcomes. Currently, a donor liver is considered a SFSG when the graft-to-recipient weight ratio is less than 0.8 or the ratio of the graft volume to the standard liver volume is less than 40%. A strategy for transplanting SFSG safely into recipients and avoiding extensive surgery in the living donor could effectively address the donor shortage. We review the literature and assess our current knowledge of and strategies for portal flow modulation in LDLT.

METHODS:BACKGROUND:Seasonal variation in the occurrence of medical illnesses reflects the effect of the environment, provides insight into pathogenesis, and can assist health care administrators in allocating resources accordingly. Seasonal variation has been reported in various infectious and surgical diseases, but has been rarely studied in acute cholecystitis. Our objective was to study seasonal variation in acute cholecystitis at our institution. METHODS:We performed a retrospective analysis of patients who underwent cholecystectomy for acute cholecystitis from January 1988 to December 2018. Chi-square goodness-of-fit test was used to analyze seasonality of acute cholecystitis adjusting for variation in number of days between seasons. The number of days for seasons were taken as 92, 92, 91, and 90.25 for spring, summer, fall, and winter, respectively. RESULTS:Overall, 3924 patients underwent cholecystectomy for acute cholecystitis during the study period. The frequency of cholecystectomies performed varied between months (minimum February n = 259, maximum July n = 372, P < 0.001) and seasons (minimum winter n = 789, maximum summer n = 1101 P < 0.001). Age and gender distribution across months and seasons was similar (P > 0.05). CONCLUSIONS:Our findings confirm seasonal variation in occurrence of acute cholecystitis with summer season witnessing the most and the winter season encountering the least patients with acute cholecystitis. Validation of our findings through prospectively collected data at national level is the way forward.

胆道疾病方向

胆道疾病指发生于胆道系统的疾病。临床上常见的胆道疾病包括结石、肿瘤、寄生虫病、先天性畸形等。胆道的病变可造成胆道梗阻使胆汁淤滞,进一步影响肝脏功能,且常导致继发感染,胆道结石等慢性刺激也可诱发恶性肿瘤。
