Primary adrenal Ewing sarcoma: A systematic review of the literature.

Background: Ewing sarcoma (ES) is a malignant neoplasm of neuroectodermal origin and is commonly observed in children and young adults. The musculoskeletal system is the main body system impacted and ES is rarely seen in the visceral organs particularly the adrenal gland.

Aim: To present a comprehensive review of primary adrenal ES, with emphasis on diagnosis, therapy and oncological outcomes.

Traumatic lumbar hernia: A systematic review of the literature.

Purpose: Traumatic lumbar hernia (TLH) constitutes a protrusion of content through a defect in the posterior abdominal wall, as a result of injury. This rare entity has been described in limited number of cases.

Methods: A systematic review of the literature was performed according to the meta-analysis of observational studies in epidemiology guidelines.

Critical View of Safety in Laparoscopic Cholecystectomy: A Systematic Review of Current Evidence and Future Perspectives.

Background: The Critical View of Safety (CVS) has been increasingly recognised as the standard method for identification of the cystic structures, to prevent vasculobiliary injuries during laparoscopic cholecystectomy, however, its adoption has been anything but universal. A significant proportion of surgeons has a poor understanding of the three requirements. To bridge this gap between theory and practice, we aimed to summarise the available evidence on CVS, emphasising on current debates and future perspectives.

Critical View of Safety in Laparoscopic Cholecystectomy: A Word of Caution in Cases of Aberrant Anatomy.

 To avoid vasculobiliary injuries, the Critical View of Safety (CVS) technique is strongly recommended during dissection of the hepatocystic triangle. It entails three basic steps as follows: (1) complete clearance of the hepatocystic triangle of fibrofatty tissue, (2) separation of the lower part of the gallbladder from the cystic plate, so that (3) two and only two structures are seen entering the gallbladder.  In this video vignette, we present the case of an aberrant hepatic artery, coursing subserosally parallel to the gallbladder wall.

Morphology of the sulcus of the caudate process (Rouviere's sulcus) in a Greek population and a systematic review with meta-analysis.

The purpose of this study was to determine the prevalence and to investigate the morphology of the sulcus of the caudate process in a Greek population, along with a systematic review and meta-analysis of the literature. Overall, 103 consecutive patients undergoing laparoscopic cholecystectomy were included in the analysis. The sulcus was present in 91% and three morphological variants were identified (groove 69%, slit 21% and scar 10%).

Revisiting Amyand's Hernia: A 20-Year Systematic Review.

Purpose: Protrusion of the appendix within an inguinal hernia is termed an Amyand's hernia. A systematic review of case reports and case series of Amyand's hernia was performed, with emphasis on surgical decision-making.

Methods: The English literature (2000-2019) was reviewed, using PubMed and Embase, combining the terms "hernia", "inguinal", "appendix", "appendicitis" and "Amyand".

Colorectal cancer metastases to the thyroid gland-a systematic review : Colorectal cancer thyroid metastases.

Background: Despite its rich vasculature, the thyroid gland is a rare site of metastatic disease. We present a systematic review of colorectal cancer (CRC) thyroid metastases, with emphasis on diagnosis, therapeutic management, and oncological outcomes.

Methods: A systematic review of the English literature (1990 to 2019) was performed, using the PubMed, Embase, and Google Scholar bibliographic databases.

Unfinished Business: A Systematic Review of Stump Appendicitis.

Background: Stump appendicitis is defined as interval inflammation of any residual appendicular tissue, after an appendicectomy. We present a systematic review of case series and case reports on stump appendicitis, emphasising on risk factors, diagnosis and surgical management.

Methods: The English literature (1945-2018) was reviewed, using PubMed, Embase and GoogleScholar, combining the terms "appendix", "appendicitis", "stump", "residual", "recurrent" and "retained".

Gastrointestinal Seed Bezoars: A Systematic Review of Case Reports and Case Series.

Seed bezoars are a distinct subcategory of phytobezoars, caused by indigestible vegetable or fruit seeds. The aim of our study was to present a comprehensive review on seed bezoars, focusing on epidemiology, symptomatology, diagnosis and treatment options. A systematic review of the English literature (1980-2018) was conducted, using PubMed, Embase and Google Scholar databases.

Ten-year Audit of Safe Bail-Out Alternatives to the Critical View of Safety in Laparoscopic Cholecystectomy.

Background: To prevent vasculobiliary injuries according to the Tokyo Guidelines, Critical View of Safety (CVS) is the recommended method for the identification of the cystic duct and cystic artery. Our aim was to audit laparoscopic cholecystectomies, in order to determine the rate of CVS feasibility and to explore safe bail-out alternatives, when CVS cannot be obtained.

Methods: Patients who underwent either elective or emergent laparoscopic cholecystectomy, between January 2009 and December 2018, in whom the CVS was attempted, were retrospectively identified from the institutional electronic database.
