Cholecystectomy for acute cholecystitis during weekend compared with delayed weekday surgery: A nationwide population cohort study.

Background: The optimal timing of surgery for acute cholecystitis has been a subject of debate, but the predominant view supports early cholecystectomy. This study investigated the safety of early cholecystectomy during weekends compared with delayed surgery until a weekday.

Methods: This was a population-based cohort study based on data from the Swedish National Register for Gallstone Surgery and Endoscopic Retrograde Cholangiopancreatography (GallRiks).

Ultrasonic dissection versus electrocautery dissection in laparoscopic cholecystectomy for acute cholecystitis: a randomized controlled trial (SONOCHOL-trial).

Background: Laparoscopic cholecystectomy with ultrasonic dissection presents a compelling alternative to conventional electrocautery. The evidence for elective cholecystectomy supports the adoption of ultrasonic dissection, citing advantages such as reduced operating time, diminished bleeding, shorter hospital stays and decreased postoperative pain and nausea. However, the efficacy of this procedure in emergency surgery and patients diagnosed with acute cholecystitis remains uncertain.

No significant persistent symptoms from gallstones left in the abdomen after cholecystectomy.

Introduction: Perforation of the gallbladder during cholecystectomy can lead to spillage of gallstones. The aim of this study was to examine if patients with gallstones left in the abdomen after cholecystectomy suffer persisting symptoms.

Method: This study was based on data from the Swedish Register for Gallstone Surgery.

Survival among 148 patients with an incidentally detected appendiceal tumours at surgery for acute appendicitis: a population-based cohort follow-up study.

Purpose: To investigate the long-term prognosis of appendiceal tumours incidentally detected at appendicectomy for suspicion of benign appendicitis.

Methods: A retrospective register-based single centre cohort study was carried out, using data from the local acute appendicectomy quality register of cases operated on at the Department of Surgery, South General Hospital, Stockholm, Sweden. The local colorectal cancer register was also used to identify appendix tumours.

Saliva stress biomarkers in ERCP trainees before and after familiarisation with ERCP on a virtual simulator.

Background: Stress during the early ERCP learning curve may interfere with acquisition of skills during training. The purpose of this study was to compare stress biomarkers in the saliva of trainees before and after familiarisation with ERCP exercises on a virtual simulator.

Methods: Altogether 26 endoscopists under training, 14 women and 12 men, completed the three phases of this study: Phase 1.

Safety of cholecystectomy performed by surgeons who prefer fundus first versus surgeons who prefer a standard laparoscopic approach.

Background: An alternative method to standard laparoscopic cholecystectomy (SLC) is the "fundus first" method (FFLC). Concerns have been raised that FFLC can lead to misinterpretation of important anatomical structures, thus causing complications of a more serious kind than SLC. Comparisons between the methods are complicated by the fact that FFLC is often used as a rescue procedure in complicated cases.

Validity of a virtual reality endoscopic retrograde cholangiopancreatography simulator: can it distinguish experts from novices?

Background: There is a lack of evidence regarding the effectiveness of virtual simulators as a means to acquire hands-on exposure to endoscopic retrograde cholangiopancreatography (ERCP). The present study aimed to assess the outcome and construct validity of virtual ERCP when training on the GI II Mentor simulator.

Methods: A group of seven experienced endoscopists were compared with 31 novices.

Learning curve in open groin hernia surgery: nationwide register-based study.

Background: Current recommendations regarding the number of open groin hernia repairs that surgical trainees are required to perform during their residency are arbitrarily defined and vary between different curricula. This register-based study sought to investigate the learning curve of surgeons performing open anterior mesh repair for groin hernia by assessing hernia recurrence rates, surgical complications and operating times in relation to the number of procedures performed.

Method: Nationwide data on open anterior mesh repair for groin hernia performed by surgical residents were collected from the Swedish Hernia Register between 2005 and 2020.

Differences in Cholecystectomy Outcomes and Operating Time Between Male and Female Surgeons in Sweden.

Importance: Female surgeons are still in the minority worldwide, and highlighting gender differences in surgery is important in understanding and reducing inequities within the surgical specialty. Studies on different surgical procedures indicate equal results, or safer outcomes, for female surgeons, but it is still unclear whether surgical outcomes of gallstone surgery differ between female and male surgeons.

Objective: To examine the association of the surgeon's gender with surgical outcomes and operating time in elective and acute care cholecystectomies.

Peritoneal Bridging Versus Nonclosure in Laparoscopic Ventral Hernia Repair: A Randomized Controlled Trial.

Introduction: Postoperative seroma and pain are common problems following laparoscopic intraperitoneal onlay mesh (IPOM) repair of ventral hernias. These adverse outcomes may be avoided by dissecting and using the peritoneum in the hernial sac to bridge the hernia defect.

Methods: This was a patient- and outcome assessor-blinded, parallel-design, randomized controlled trial comparing nonclosure and peritoneal bridging approaches in patients scheduled for elective midline ventral hernia repair.

Effect of the SARS-CoV-2 pandemic on planned and emergency hernia repair in Sweden: a register-based study.

Purpose: The COVID-19 has had a profound impact on the health care delivery in Sweden, including deprioritization of benign surgeries during the COVID-19 pandemic. The aim of this study was to assess the effect of COVID-19 pandemic on emergency and planned hernia repair in Sweden.

Methods: Data on hernia repairs from January 2016 to December 2021 were retrieved from the Swedish Patient Register using procedural codes.

The use of simulators to acquire ERCP skills: a systematic review.

Unlabelled: Endoscopic retrograde cholangiopancreatography (ERCP) is a technically demanding diagnostic and therapeutic endoscopic procedure with a high risk for adverse events such as post-ERCP pancreatitis and bleeding. Since endoscopists with less experience have higher adverse event rates, the training of new residents on ERCP simulators has been suggested to improve the resident's technical skills necessary for ERCP. However, there is a lack of consensus on whether the training program should focus on a threshold number of procedures or be more tailored to the individual's performance.

Long-term health-related quality of life after trauma with and without traumatic brain injury: a prospective cohort study.

To purpose was to assess and compare the health-related quality of life (HRQoL) and risk of depression two years after trauma, between patients with and without traumatic brain injury (TBI) in a mixed Swedish trauma cohort. In this prospective cohort study, TBI and non-TBI trauma patients included in the Swedish Trauma registry 2019 at a level II trauma center in Stockholm, Sweden, were contacted two years after admission. HRQoL was assessed with RAND-36 and EQ-5D-3L, and depression with Montgomery Åsberg depression Rating Scale self-report (MADRS-S).

Perioperative water and electrolyte balance and water homeostasis regulation in children with acute surgery.

Background: Hospital-acquired hyponatremia remains a feared event in patients receiving hypotonic fluid therapy. Our objectives were to assess post-operative plasma-sodium concentration and to provide a physiological explanation for plasma-sodium levels over time in children with acute appendicitis.

Methods: Thirteen normonatremic (plasma-sodium ≥135 mmol/L) children (8 males), median age 12.

Relationship between surgical volume and outcomes in elective and acute cholecystectomy: nationwide, observational study.

Background: High surgical volumes are attributed to improved quality of care, especially for extensive procedures. However, it remains unknown whether high-volume surgeons and hospitals have better results in gallstone surgery. The aim of this study was to investigate whether operative volume affects outcomes in cholecystectomies.

Timing of Elective Cholecystectomy After Acute Cholecystitis: A Population-based Register Study.

Background: Acute cholecystectomy is standard treatment for acute cholecystitis. However, many patients are still treated conservatively and undergo delayed elective surgery. The aim of this study was to determine the ideal time to perform an elective cholecystectomy after acute cholecystitis.
