Directly after completing the course, participants evaluated it using a 25-question post-course questionnaire (POST1). At least 12 months after the course, participants received a follow-up questionnaire (POST2) by mail.

Data were gathered from 241 participants. After the course, 182 POST2 questionnaires were mailed, 61 of which were returned (equals a 39 % return rate). The findings revealed significant increases in teacher self-efficacy (p=0.0025), identified regulation (p=0.0000), and career motivation (p=0.0044). In contrast, there was a significant decrease in introjected regulation (p=0.0048).

However, the liver anatomy is very complex, and liver surgery is still associated with relevant morbidity despite many technical advances. The Brisbane nomenclature is used worldwide to classify liver resection. However, this nomenclature has several limitations as multiple terms are used for the same type of resection. Non-anatomical resections, multiple resections, and combined bilio-vascular resections were not mentioned. Therefore, new terminologies have been proposed for the precise and simple classification of liver resection. Furthermore, in recent years, many technical innovations have been introduced in liver surgery, such as 3D imaging systems and indocyanine green fluorescence, for better preoperative and intraoperative identification of tumor localization and critical vascular structures. Minimally invasive techniques are used more frequently in liver surgery. Potential benefits include less intraoperative blood loss, less pain, and a shorter hospital stay. The implementation of robotic systems also has an impact on liver surgery, and the number of cases reported in the literature is constantly increasing. The potential benefits of robotic liver resection over laparoscopic liver resection will be the subject of future studies.","PeriodicalId":44186,"journal":{"name":"Innovative Surgical Sciences","volume":"57 6","pages":""},"PeriodicalIF":1.3,"publicationDate":"2024-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139386665","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, endovas-cular treatment options have emerged that eliminate the need for invasive open surgery. Several endograft devices – with fenestrations or branches for the supraaortic vessels – are currently available to address different pathologies and anatomical variations. Parallel-graft techniques and in situ fenestrations expand the treatment options for emergent cases. In this selective review of the literature of 2020 and 2021, we summarize the current chances and challenges of endovascular aortic repair. Content Reported mortality rates range from 0 to 13.2 %. Although technical success rates for fenestrated and branched devices are promising (98 %), stroke rates remain a relevant issue (10 and 3 % for BTEVAR and FTEVAR respectively). The reported technical success rate for in situ fenestrations is also encouraging (94 %) and the stroke rates acceptable (5 %). Parallel-graft techniques are associated with high early and late endoleak rates (early 76 %; late 31 %), but still hold a valuable place in the treatment of emergent cases or in bail-out situations. Summary and Outlook The endovascular repair of the aortic arch expands the range of patients with pathologies of the arch eligible for treatment to those unfit for open surgery offering a minimally invasive, yet technically challenging procedure. More data and meta-analyses are needed to define the benefits and drawbacks of this promising treatment option in an aging population with increasing co-morbidities.","PeriodicalId":44186,"journal":{"name":"Innovative Surgical Sciences","volume":"25 ","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139172810","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to pre-existing comorbidities, the prevalence of anticoagulated patients is increasing. The right timing for surgery and perioperative anticoagulation treatment remains controversial. Content This overview aims to summarize current practices in the pre- and postoperative anticoagulation management and the recommended time to surgery in elderly patients with PFF. Summary and Outlook Time to surgery for anticoagulated patients is often prolonged due to worries about serious perioperative bleeding and higher transfusion demands. But the delay of surgical PFF treatment increases the risk for perioperative complications like pulmonary embolism, pneumonia, deep vein thrombosis and urinary tract infections. Early surgery can be achieved with a consistent and interdisciplinary perioperative anticoagulation management. Antiplatelets do not have to be discontinued and surgery should be performed early without delay. For patients taking vitamin K antagonists (VKA) an INR less than 1.5 is recommended prior to surgery, which can be achieved by pausing VKA intake or by administering vitamin K, prothrombin complex concentrate (PCC) or fresh frozen plasma (FFP). For the treatment with direct oral anticoagulants (DOAC) a plasma drug level of under 50 pg/mL is considered safe for surgery. If the plasma level can not be determined, a gap of 24 h between the last DOAC dose and surgery is recommended. The systemic administration of tranexamic acid can reduce overall blood loss and transfusion rates in anticoagulated patients with PFF. Surgical treatment of PFF should be performed within 24 h, as delayed surgery increases the risk for perioperative complications. This also applies to anticoagulated patients, when clinically appropriate. International and interdisciplinary guidelines are necessary to ensure early and appropriate treatment of anticoagulated elderly patients with PFF.","PeriodicalId":44186,"journal":{"name":"Innovative Surgical Sciences","volume":"63 2","pages":""},"PeriodicalIF":1.3,"publicationDate":"2023-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138600723","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Accordingly, multivisceral resection (MVR) must be performed in these patients. This prospective multicenter observational study aimed to analyze the possible differences between non-multivisceral resection (nMVR) and MVR in terms of early postoperative and long-term oncological treatment outcomes. We also aimed to determine the factors influencing overall survival.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;The data of 25,321 patients from 364 hospitals who had undergone surgery for CRC (the Union for International Cancer Control stages I-III) during a defined period were evaluated. MVR was defined as (partial) resection of the tumor-bearing organ along with resection of the adherent and adjacent organs or tissues. In addition to the patients' personal, diagnosis (tumor findings), and therapy data, demographic data were also recorded and the early postoperative outcome was determined. Furthermore, the long-term survival of each patient was investigated, and a \"matched-pair\" analysis was performed.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;From 2008 to 2015, the MVR rates were 9.9 % (n=1,551) for colon cancer (colon CA) and 10.6 % (n=1,027) for rectal cancer (rectal CA). CRC was more common in men (colon CA: 53.4 %; rectal CA: 62.0 %) than in women; all MVR groups had high proportions of women (53.6 % vs. 55.2 %; pairs of values in previously mentioned order). Resection of another organ frequently occurred (75.6 % vs. 63.7 %). The MVR group had a high prevalence of intraoperative (5.8 %; 12.1 %) and postoperative surgical complications (30.8 % vs. 36.4 %; each p&lt;0.001). Wound infections (colon CA: 7.1 %) and anastomotic insufficiencies (rectal CA: 8.3 %) frequently occurred after MVR. The morbidity rates of the MVR groups were also determined (43.7 % vs. 47.2 %). The hospital mortality rates were 4.9 % in the colon CA-related MVR group and 3.8 % in the rectal CA-related MVR group and were significantly increased compared with those of the nMVR group (both p&lt;0.001). Results of the matched-pair analysis showed that the morbidity rates in both MVR groups (colon CA: 42.9 % vs. 34.3 %; rectal CA: 46.3 % vs. 37.2 %; each p&lt;0.001) were significantly increased. The hospital lethality rate tended to increase in the colon CA-related MVR group (4.8 % vs. 3.7 %; p=0.084), while it significantly increased in the rectal CA-related MVR group (3.4 % vs. 3.0 %; p=0.005). Moreover, the 5-year (yr) overall survival rates were 53.9 % (nMVR: 69.5 %; p&lt;0.001) in the colon CA group and 56.8 % (nMVR: 69.4 %; p&lt;0.001) in the rectal CA group.
