Background: This systematic review aims to investigate whether percutaneous transhepatic gallbladder biliary drainage (PTGBD) is superior to emergency cholecystectomy (EC) as a definitive treatment in high-risk patients with acute cholecystitis (AC).

Material And Methods: A systematic literature search was performed until December 2022 using the Scopus, Medline/PubMed and Web of Science databases.

Results: Seventeen studies have been included with a total of 783,672 patients (32,634 treated with PTGBD vs.

Background: Prophylactic negative-pressure wound therapy (pNPWT) may prevent surgical site infection (SSI) after laparotomy, but existing meta-analyses pooling only high-quality evidence have failed to confirm this effect. Recently, several randomized controlled trials (RCTs) have been published. We performed an updated systematic review and meta-analysis to determine if pNPWT reduces the incidence of SSI after laparotomy.

Professional surgical societies recommend the identification and treatment of pre-operative anaemia in patients scheduled for abdominal surgery. Our aim was to determine if pre-operative iron allows correction of haemoglobin concentration and decreased incidence of peri-operative blood transfusion in patients undergoing major abdominal surgery. MEDLINE, Embase and CENTRAL were searched for RCTs written in English and assessing the effect of pre-operative iron on the incidence of peri-operative allogeneic blood transfusion in patients undergoing major abdominal surgery.

Background: Several treatment strategies for avoiding post-operative ileus have been evaluated in randomised controlled trials. This network meta-analysis aimed to explore the relative effectiveness of these different therapeutic interventions on ileus outcome measures.

Methods: A systematic literature review was performed to identify randomized controlled trials (RCTs) comparing treatments for post-operative ileus following colorectal surgery.

Background: Doctors play a key role in individuals' lives undergoing a holistic integration into local communities. To maintain public trust, it is essential that professional values are upheld by both doctors and medical students. We aimed to ensure that students appreciated these professional obligations during the 3-year science-based, preclinical course with limited patient contact.

Unlabelled: The role of lateral lymph node dissection (LLND) during total mesorectal excision (TME) for rectal cancer is still controversial. Many reviews were published on prophylactic LLND in rectal cancer surgery, some biased by heterogeneity of overall associated treatments. The aim of this systematic review and meta-analysis is to perform a timeline analysis of different treatments associated to prophylactic LLND vs no-LLND during TME for rectal cancer.

Carl Wernicke described the disease bearing his name in 1881 and reported three cases characterized by the presence of mental confusion, ataxia, and ophthalmoplegia. Wernicke's disease is mainly observed in alcoholic patients, due to decreased vitamin intake as a consequence of an unbalanced diet, and a reduction of absorption due to the effects of alcohol. Likewise, inadequate vitamin intake is prevalent in older patients.

Background And Aims: Acute appendicitis (AA) is among the most common causes of acute abdominal pain. Diagnosis of AA is still challenging and some controversies on its management are still present among different settings and practice patterns worldwide. In July 2015, the World Society of Emergency Surgery (WSES) organized in Jerusalem the first consensus conference on the diagnosis and treatment of AA in adult patients with the intention of producing evidence-based guidelines.

Objective: The aim of this meta-analysis was to summarize the current available evidence on nonoperative management (NOM) with antibiotics for uncomplicated appendicitis, both in adults and children.

Summary Background Data: Although earlier meta-analyses demonstrated that NOM with antibiotics may be an acceptable treatment strategy for patients with uncomplicated appendicitis, evidence is limited by conflicting results.

Methods: Systematic literature search was performed using MEDLINE, the Cochrane Central Register of Controlled Trials, and EMBASE databases for randomized and nonrandomized studies comparing antibiotic therapy (AT) and surgical therapy-appendectomy (ST) for uncomplicated appendicitis.
