Article Synopsis
  • The study aims to assess how socioeconomic deprivation affects postoperative outcomes in patients who have undergone surgery for sigmoid diverticulitis (SD).
  • Conducted across 41 French hospitals from 2010 to 2021, researchers found that 20% of the 6,415 patients experienced severe complications within 90 days post-surgery.
  • Results indicated that higher levels of socioeconomic deprivation are linked to an increased risk of severe complications, even after adjusting for factors like age, sex, and surgery type.

Introduction: Acute cholecystitis occurs frequently in the elderly. According to the current recommendations specific to the characteristics of each case, these patients are most often treated by delayed cholecystectomy after medical treatment. Our study aimed to compare the success rate of this strategy in patients over and under 75years of age.

Aim: The aim of this work was to investigate the association between early postoperative anastomotic leakage or pelvic abscess (AL/PA) and symptomatic anastomotic stenosis (SAS) in patients after surgery for left colonic diverticulitis.

Method: This is a retrospective study based on a national cohort of diverticulitis surgery patients carried out by the Association Française de Chirurgie. The assessment was performed using path analyses.

Article Synopsis
  • Recent clinical trials show that using a prophylactic mesh does not significantly lower the rate of parastomal hernias, and there's limited data on its effects on symptoms and quality of life.
  • The study aimed to analyze whether the type of mesh used (or lack thereof) affected symptoms and complications in patients with parastomal hernias from the GRECCAR 7 trial.
  • Results indicated no significant difference in parastomal hernia diagnosis or symptoms between the mesh and non-mesh groups after two years, but the study was limited by a small sample size and incomplete data.

Background: The observed increase in the incidence of complicated diverticulitis may lead to the performance of more emergency surgeries. This study aimed to assess the rate and risk factors of emergency surgery for sigmoid diverticulitis.

Method: The primary outcomes were the rate of emergency surgery for sigmoid diverticulitis and its associated risk factors.

Article Synopsis
  • Uterine innervation is crucial to female reproductive health and has significant implications for conditions like endometriosis; recent histological advances have revealed its complex structure and role in these disorders.
  • This review summarizes current research on uterine innervation, focusing on its effects on endometriosis and associated pain, using a systematic approach to analyze relevant studies.
  • The review identified 45 studies that highlighted a trend towards increased nerve fiber density in ectopic endometrial tissue, suggesting a link between this heightened innervation and the chronic pain seen in endometriosis patients.

Objectives: The aim of this study was to compare endoscopic ultrasound-guided choledochoduodenostomy (EUS-CDS) vs. EUS-gallbladder drainage (EUS-GBD) in cases of failed endoscopic retrograde cholangiopancreatography (ERCP) for jaundice resulting from malignant distal biliary obstruction (MDBO).

Methods: This multicenter retrospective study included patients with obstructive jaundice secondary to MDBO who underwent EUS-GBD or EUS-CDS with lumen-apposing metal stents after failed ERCP.

Article Synopsis
  • The study examined human fetal anatomy very early post-mortem at 8 weeks of gestation using advanced imaging technologies like micro-CT and high-field MRI.
  • Nine fetuses were analyzed, showing the imaging provided clear anatomical details without damaging the tissue, allowing for further histological study.
  • The research indicates that these imaging techniques enable early virtual autopsy, which could assist in genetic counseling for parents dealing with miscarriage.

Healthcare sectors, particularly operating theaters, are major consumers of resources. Given today's climate-related issues, its seems vital that the different healthcare professionals in operating areas become aware of their roles. This is pronouncedly the case for hospital pharmacists, who fulfill cross-sectional functions in the proper use and management of healthcare products and sterile medical devices.

Objective: To analyze the surgical management of sigmoid diverticular disease (SDD) before, during, and after the first containment rules (CR) for the first wave of COVID-19.

Methods: From the French Surgical Association multicenter series, this study included all patients operated on between January 2018 and September 2021. Three groups were compared: A (before CR period: 01/01/18-03/16/20), B (CR period: 03/17/20-05/03/20), and C (post CR period: 05/04/20-09/30/21).

Purpose: External snapping hip is caused by the iliotibial band snapping from the greater trochanter during hip movement. The aim of this study was to compare a technique of ultrasound-guided iliotibial band release versus a similar endoscopic technique.

Methods: An anatomical study was performed on 10 cadavers i.

Introduction: Erector spinae plane block has been proposed to reduce opioid use and improve pain relief with controversial results. This randomized clinical study aimed to assess the efficacy of erector spinae plane block in major spine surgery including multimodal and 'Enhance Recovery After Surgery' programs.

Method: After institutional review board approval, adult patients undergoing elective lumbar spine surgery with standardized general anesthesia, rehabilitation and multimodal analgesia protocols were randomly allocated to receive bilateral ultrasound-guided block with saline versus ropivacaine (3.

Article Synopsis
  • This study aimed to map the anatomy and function of nerve innervation in the human uterus to enhance understanding of pelvic pain conditions like endometriosis.* -
  • Researchers dissected female fetal pelvises to create a 3D reconstruction model, identifying nerve types and their distribution throughout different layers of the uterus.* -
  • The findings revealed diverse nerve fiber types and densities, highlighting rich innervation in certain areas, which could inform future therapeutic strategies for uterine pain disorders.*

Mechanisms of drug-tolerance remain poorly understood and have been linked to genomic but also to non-genomic processes. 5-fluorouracil (5-FU), the most widely used chemotherapy in oncology is associated with resistance. While prescribed as an inhibitor of DNA replication, 5-FU alters all RNA pathways.

Background: Many computed tomography (CT) navigation systems have been developed to help radiologists improve the accuracy and safety of the procedure. We evaluated the accuracy of one CT computer-assisted guided procedure with different reduction dose protocols.

Methods: A total of 128 punctures were randomly made by two operators on two different anthropomorphic phantoms.

Introduction: During the COVID-19 pandemic, cancer patients have been regarded as having a high risk of severe events if they are infected with SARS-CoV-2, particularly those under medical or surgical treatment. The aim of this study was to assess the posttreatment risk of infection by SARS-CoV-2 in a population of patients operated on for colorectal cancer 3 months before the COVID-19 outbreak and who after hospitalization returned to an environment where the virus was circulating.

Materials And Methods: This French, multicenter cohort study included consecutive patients undergoing elective surgery for colorectal cancer between January 1 and March 31, 2020, at 19 GRECCAR hospitals.

Objective: The primary endpoint of this meta-analysis was the PSH rate at 1 year of follow-up with or without the use of a mesh.

Summary Of Background Data: European guidelines currently recommend the use of a mesh at the time of a stoma formation for the prevention of PSH. These recommendations are based on the RCT and meta-analyses published before 2017.

Objective: To evaluate whether systematic mesh implantation upon primary colostomy creation was effective to prevent PSH.

Summary Of Background Data: Previous randomized trials on prevention of PSH by mesh placement have shown contradictory results.

Methods: This was a prospective, randomized controlled trial in 18 hospitals in France on patients aged ≥18 receiving a first colostomy for an indication other than infection.

Background: Good management of disposable and reusable supplies may improve surgical efficiency in the operating room (OR) and also corresponds to the best eco-responsible approach. The purpose of this study was to assess the impact of a clinical pharmacist's intervention in the OR on the non-compliant use of medical devices. We also assessed the economic impact of the pharmaceutical intervention.
