The anatomical location of the pancreas and the sparse distribution of islets limit the study of islets in vivo, while the unique physiological structure of the anterior chamber of the eye provides a new technical method for long-term, non-invasive, real-time and in vivo physiological study of transplanted islets. In recent years, through the experimental study of rodents and non-human primates, great progress has been made in the survival, functional regulation and pathophysiological changes of islets after transplantation. This article will focus on the current research progress of islet transplantation in the anterior chamber of the eye, and the advantages and disadvantages of this technical method are introduced as well.

脾脏窦岸细胞血管瘤是一种少见的脾脏血管源性肿瘤,无明显特异性临床表现,常伴恶性肿瘤及免疫性疾病.多因偶然原因发现,其主要依靠影像学检查和病理学检查确定诊断.该肿瘤性质大多数呈良性发展,极少数存在恶性倾向.目前治疗主要为手术切除,可获得治愈,但也有肿瘤复发转移的报道.该疾病在临床上较为罕见,临床医生往往缺乏认识,容易漏诊、误诊.现就该疾病的诊断治疗现状进行综述,旨在为临床诊治提供参考.

急性胆囊炎是常见的外科急腹症,腹腔镜胆囊切除是首选治疗方法.但部分高龄、伴随严重基础疾病、合并重要脏器功能不全或凝血功能异常等高危患者,手术病死率和并发症发生率均较高,采取简单、快速、微创的胆囊引流方式是重要的治疗原则.经皮经肝胆囊穿刺引流术、经皮经肝胆囊穿刺抽吸术和经皮胆囊造瘘术是临床常用的治疗措施,近年来内镜经十二指肠乳头胆囊引流术、内镜超声引导下胆囊引流术等新的引流技术不断出现,在临床应用中取得了良好的效果,每种术式各有其优缺点和适应症.本文就高危急性胆囊炎患者引流治疗的现状进行综述,为临床医生的治疗选择提供参考.
