Total extraperitoneal endoscopic hernioplasty (TEP) versus Lichtenstein hernioplasty: a systematic review by updated traditional and cumulative meta-analysis of randomised-controlled trials.

Background-purpose: Totally extraperitoneal (TEP) endoscopic hernioplasty and Lichtenstein hernioplasty are the most commonly used approaches for inguinal hernia repair. However, current evidence on which is the preferred approach is inconclusive. This updated meta-analysis was conducted to track the accumulation of evidence over time.

Post-operative outcomes and predictors of mortality after colorectal cancer surgery in the very elderly patients.

Background: The frailty of the very elderly patients who undergo surgery for colorectal cancer negatively influences postoperative mortality. This study aimed to identify risk factors for postoperative mortality in octogenarian and nonagenarian patients who underwent surgical treatment for colorectal cancer.

Methods: This is a single institution retrospective study.

Emergency repair of complicated abdominal wall hernias: WSES guidelines.

Purpose: In July 2013, the World Society of Emergency Surgery (WSES) held the first Consensus Conference on emergency repair of abdominal wall hernias in adult patients with the intention of producing evidence-based guidelines to assist surgeons in the management of complicated abdominal wall hernias. Guidelines were updated in 2017 in keeping with varying clinical practice: benefits resulting from the increased use of biological prosthesis in the emergency setting were highlighted, as previously published in the World Journal of Emergency Surgery. This executive summary is intended to consolidate knowledge on the emergency management of complicated hernias by providing the broad readership with a practical and concise version of the original guidelines.

Factors affecting the number of lymph nodes retrieved after colo-rectal cancer surgery: A prospective single-centre study.

Background: The number of harvested lymph nodes (LNs) in colorectal cancer surgery relates to oncologic radicality and accuracy of staging. In addition, it affects the choice of adjuvant therapy, as well as prognosis. The American Joint Committee on Cancer defines at least 12 LNs harvested as adequate in colorectal cancer resections.

The Application of Indocyanine Green Fluorescence Imaging During Robotic Liver Resection: A Case-Matched Study.

Background: The ICG fluorescence properties are progressively gaining momentum in the HPB surgery. However, the exact impact of ICG application on surgical outcomes is yet to be established.

Methods: Twenty-five patients who underwent ICG fluorescence-guided robotic liver resection were case-matched in a 1:1 ratio to a cohort who underwent standard robotic liver resection.

2019 WSES guidelines for the management of severe acute pancreatitis.

Although most patients with acute pancreatitis have the mild form of the disease, about 20-30% develops a severe form, often associated with single or multiple organ dysfunction requiring intensive care. Identifying the severe form early is one of the major challenges in managing severe acute pancreatitis. Infection of the pancreatic and peripancreatic necrosis occurs in about 20-40% of patients with severe acute pancreatitis, and is associated with worsening organ dysfunctions.

Hartmann's procedure versus sigmoidectomy with primary anastomosis for perforated diverticulitis with purulent or faecal peritonitis (LADIES): a multicentre, parallel-group, randomised, open-label, superiority trial.

Background: Previous studies have suggested that sigmoidectomy with primary anastomosis is superior to Hartmann's procedure. The likelihood of stoma reversal after primary anastomosis has been reported to be higher and reversal seems to be associated with lower morbidity and mortality. Although promising, results from these previous studies remain uncertain because of potential selection bias.

Bowel obstruction: a narrative review for all physicians.

Small and large bowel obstructions are responsible for approximately 15% of hospital admissions for acute abdominal pain in the USA and ~ 20% of cases needing acute surgical care. Starting from the analysis of a common clinical problem, we want to guide primary care physicians in the initial management of a patient presenting with acute abdominal pain associated with intestinal obstruction.

Esophageal emergencies: WSES guidelines.

The esophagus traverses three body compartments (neck, thorax, and abdomen) and is surrounded at each level by vital organs. Injuries to the esophagus may be classified as foreign body ingestion, caustic ingestion, esophageal perforation, and esophageal trauma. These lesions can be life-threatening either by digestive contamination of surrounding structures in case of esophageal wall breach or concomitant damage of surrounding organs.

Enhancing the emergency general surgical service: an example of the aggregation of marginal gains.

Introduction: We aimed to enhance the emergency general surgical service in our high-volume centre in order to reduce four-hour target breaches, to expedite senior decision making and to avoid unnecessary admissions.

Materials And Methods: The aggregation of marginal gains theory was applied. A dual consultant on-call system was established by the incremental employment of five emergency general surgeons with a specialist interest in colorectal or oesophagogastric surgery.

Prophylactic intra-abdominal drainage following colorectal anastomoses. A systematic review and meta-analysis of randomized controlled trials.

Background: Clinically evident Anastomotic Leakage (AL) remains one of the most feared complications after colorectal resections with primary anastomosis. The primary aim of this systematic review and meta-analysis was to determine whether Prophylactic Drainage (PD) after colorectal anastomoses confers any advantage in the prevention and management of AL.

Methods: Systematic literature search was performed using MEDLINE, the Cochrane Central Register of Controlled Trials, and EMBASE databases for randomized studies comparing clinical outcomes of patients with Drained (D) or Undrained (UD) colorectal anastomoses performed for any cause.

Educational value of surgical videos on YouTube: quality assessment of laparoscopic appendectomy videos by senior surgeons vs. novice trainees.

Background: To prepare for surgery, surgeons often recur to surgical videos, with YouTube being reported as the preferred source. This study aimed to compare the evaluation of three surgical trainees and three senior surgeons of the 25 most viewed laparoscopic appendectomy videos listed on YouTube. Additionally, we assessed the video conformity to the published guidelines on how to report laparoscopic surgery videos (LAP-VEGaS).

Hypothyroidism as a Predictor of Surgical Outcomes in the Elderly.

There is a high prevalence of hypothyroidism in the elderly population, mainly among women. The most important cause is autoimmune thyroiditis, but also iodine deficiency, radioiodine ablation, and surgery may be responsible for hypothyroidism in elderly hospitalized patients. Thyroid-related symptoms are sometimes comparable to physiological manifestations of the aging process, and hypothyroidism may be related with many symptoms which can be present in critical patients, such as cognitive impairment, cardiovascular, gastrointestinal, and hematological alterations, and eventually myxedema coma which is a severe and life-threatening condition in older adults.

"Pop in a scope": attempt to decrease the rate of unnecessary nontherapeutic laparotomies in hemodynamically stable patients with thoracoabdominal penetrating injuries.

Background: Management of patients with thoracoabdominal penetrating injuries is challenging. Thoracoabdominal penetrating trauma may harbor hollow viscus injuries in both thoracic and abdominal cavities and occult diaphragmatic lesions. While radiological tests show poor diagnostic performance in these situations, evaluation by laparoscopy is highly sensitive and specific.

Gangrenous cholecystitis in male patients: A study of prevalence and predictive risk factors.

Backgrounds/aims: The prevalence and risk factors of gangrenous cholecystitis in male are unknown.

Objective: To verify the prevalence and risk factors of gangrenous cholecystitis in males.

Methods: This cross-sectional study includes 95 patients (59.

2019 update of the WSES guidelines for management of () infection in surgical patients.

In the last three decades, infection (CDI) has increased in incidence and severity in many countries worldwide. The increase in CDI incidence has been particularly apparent among surgical patients. Therefore, prevention of CDI and optimization of management in the surgical patient are paramount.

Hyperbilirubinemia as a Predictor of Appendiceal Perforation: A Systematic Review and Diagnostic Test Meta-Analysis.

Background: Misdiagnosis of the severity of acute appendicitis may lead to perforation and can consequently result in increased morbidity and mortality. In this study, the role of hyperbilirubinemia as a predictor of perforation is assessed by performing a meta-analysis of diagnostic accuracy.

Methods: A systematic search of the literature published over the past 20 years was performed using the EMBASE, PubMed, Cochrane library, and Google Scholar databases.
