The burden of predatory journal and congress requests in foot and ankle surgery

IntroductionIn recent years the proportion of predatory invitations by email of the total number of emails received has grown dramatically. The aim of the current study was to objectify the increase in predatory journal and congress requests per email over a 5.5-year period and their relatedness to the receivers’ speciality in Foot and Ankle surgery.Material and methodA comprehensive Microsoft Outlook^® analysis of 5.5 years’ worth of junk email from one surgical Foot & Ankle specialist working at a Level-1 trauma centre was evaluated. The topic of each email from the last year was scored according to the ‘degree-of-relatedness’.ResultsBetween July 1^st 2013 and December 31^th 2018 a total of 41,687 emails were collected in the junk email folder of Microsoft Outlook^®. A total of 17.0 percent was attributed to emails from predatory journals and congresses. Over the 5.5-year period the percentage of total emails that consisted of invitations from predatory journals and congresses rose from 4.5% to 40.8%. Only an insignificant amount (2.3%) was directly related to the authors medical sub-speciality of Foot and Ankle surgery.ConclusionThis is the first study showing the individual burden of unsolicited emails from predatory publishers and journals. The authors acknowledge the risk that this publication, like all others, will likely result in yet even more invitations from predatory journals and congress invitations. All should be warned of a huge increase in emails from predatory journals and congresses, which has likely not peaked yet. Appropriate action is needed, as we urge foot–ankle interested scientists to publish in indexed journals with proper peer review.     

The heavy price of conversion from laparoscopic to open procedures for emergent cholecystectomies

Background

Laparoscopic cholecystectomy (LC) is the standard operative intervention for gallbladder disease. Complications may necessitate conversion to an open cholecystectomy (OC). This study aims to determine the cost-consequences of laparoscopic-to-open conversion using a nationally-representative sample.

腹腔镜手术治疗胃十二指肠溃疡穿孔的临床效果观察

目的探讨腹腔镜手术治疗胃十二指肠溃疡穿孔的临床疗效。方法回顾性分析我院收治的108例胃十二指肠溃疡穿孔患者的临床资料,根据手术治疗方法不同分为治疗组和对照组各54例,对照组患者采用开腹手术治疗,治疗组患者采用腹腔镜手术治疗,比较两组的临床疗效。结果治疗组患者的总有效率96.30%,显著高于对照组患者的81.48%,两组比较差异具有统计学意义(P<0.05);治疗组患者手术时间、术中出血量、肛门排气时间和住院时间均显著少于对照组患者(P<0.05);治疗组患者的并发症发生率为7.41%,显著低于对照组患者的22.22%(P<0.05)。结论腹腔镜手术治疗胃十二指肠溃疡穿孔临床效果显著,术中创伤性小,术后恢复快,并发症发生率低。     

“Open” approach to aortic arch aneurysm repair

Aortic arch aneurysm is a relatively rare entity in cardiac surgery. Repair of such aneurysms, either in isolation or combined with other cardiac procedures, remains a challenging task. The need to produce a relatively bloodless surgical field with circulatory arrest, while at the same time protecting the brain, is the hallmark of this challenge. However, a clear understanding of the topic allows a better and less morbid approach to such a complex surgery.Literature has shown the advantage of selective cerebral perfusion techniques in comparison with only circulatory arrest. Ability to perfuse the brain has allowed circulatory arrest temperatures at moderate hypothermia without the need for deep hypothermia. Even though cannulation site selection appears to be a minor issue, literature has shown that the subclavian/axillary route has the best outcomes and that femoral cannulation should only be reserved for no access patients. Although different techniques for arch anastomosis have been described, we routinely perform the distal first technique as we find it to be less cumbersome and easiest to reproduce.In this review our aim is to outline a systematic approach to aortic arch surgery. Starting with indications for intervention and proceeding with approaches on site of cannulation, approaches to brain protection with hypothermia and selective cerebral perfusion and finally surgical steps in performing the distal and arch vessels anastomosis.     

开腹胆道旁路手术治疗胆管癌的效果分析

目的：探讨开腹胆道旁路手术治疗胆管癌的效果。方法60例胆管癌患者，根据随机数字表法分为治疗组与对照组，各30例。对照组采用传统手术切除治疗，治疗组采用开腹胆道旁路手术治疗。结果所有患者都顺利完成手术，治疗组的术中出血量、术后住院时间、术后下床活动时间与术后肛门排气时间明显低于对照组（P＜0．05），而2组手术时间对比差异无统计学意义。2组术前的血清总胆红素值都呈现为高位状况，术后都明显降低（P＜0．05），同时术后治疗组的血清总胆红素值明显低于对照组（P＜0．05）；治疗组术后切口感染、肺部感染、胆漏、低氧血症、粘连性肠梗阻等并发症发生率明显低于对照组（P＜0．05）。术后随访6个月，治疗组复发率为0，对照组为16．7％，治疗组复发率明显低于对照组（P＜0．05）。结论开腹胆道旁路手术治疗胆管癌具有明显的微创优势，能促进胆功能的恢复，减少术后并发症的发生与远期复发率，值得推广应用。     

A “closed fracture” with a neighbouring venous ulcer

This is a case report of a 57-year-old lady that sustained a fracture of her distal tibia and fibula. In close proximity to the fracture was a chronic venous ulcer. She was treated as a closed fracture with an intramedullary nail and subsequently developed an infection, requiring further surgery, a prolonged course of antibiotics and 3 months stay in hospital in an attempt to save her leg. Any soft tissue defect close to a fracture should be treated as a source of contamination and infection and should be treated accordingly to avoid significant complications.
