Objective: To validate the application of the Physiological and Operative Severity Score for the enumeration of Mortality and morbidity (POSSUM) system in Uruguay in order to validate its broader utility not only for predicting surgical results but also for comparing surgical outcomes in two different healthcare institutions in Montevideo.
Patients And Method: A total of 815 patients in 2 institutions (one public and the other private) were prospectively studied. A POSSUM score was assigned, expected morbidity and mortality according to POSSUM [(and its variant, Portsmouth PSSUM (p-POSSUM)] were calculated, and postoperative complications and deaths were registered.
Results: Observed morbidity and mortality were within the range predicted by POSSUM (and p-POSSUM) application. The use of these scores showed no significant differences in surgical outcomes between the two institutions, considering the different mix of patients and interventions.
Conclusion: The authors conclude that the POSSUM scoring system can be used in different surgical settings. In the future, this system will be highly useful to compare different surgical outcomes among institutions, regions and countries all over the world.

Early Reinitiation of Obesity Pharmacotherapy Post Laparoscopic Sleeve Gastrectomy in Youth: A Retrospective Cohort Study.
Obes Surg
January 2025
Division of Upper Gastrointestinal and General Surgery, Department of Surgery, Keck Medical Center of University of Southern California, Los Angeles, USA.
Background: Bariatric surgery is the most effective intervention for severe pediatric obesity, but a subset of youth experience suboptimal weight loss and/or recurrent weight gain. Early re-initiation of obesity pharmacotherapy postoperatively may improve outcomes, though this has not been evaluated in pediatric populations.
Methods: A retrospective cohort study at a tertiary care children's hospital evaluated the safety and efficacy of reintroducing obesity pharmacotherapy within six weeks after laparoscopic sleeve gastrectomy (LSG).
Partial versus radical cystectomy in localized colorectal cancer: a systematic review and meta-analysis.

January 2025
Department of Colorectal Surgery, Heliopolis Hospital, São Paulo, SP, Brazil.
Purpose: Locally advanced colorectal tumors frequently invade adjacent organs, particularly the urinary bladder in the sigmoid colon and upper rectum, complicating multivisceral resections. This study compared postoperative outcomes of partial cystectomy (PC) and total cystectomy (TC) in patients with locally advanced colorectal cancer.
Methods: A systematic review was conducted in PubMed, Scopus, Central Register of Clinical Trials, and Web of Science for studies published up to November 2024.

Department of Anesthesiology, the First Affiliated Hospital, Sun Yat-sen University, No.58, Zhongshan 2Nd Road, Guangzhou, 510080, China.
Purpose: Perioperative respiratory adverse event (PRAE) is one of the most common complications in pediatric anesthesia. We aimed to evaluate the efficacy of perioperative pharmacological interventions to prevent the development of PRAE in children undergoing noncardiac surgery.
Methods: PubMed, Embase, Cochrane Library and ClinicalTrials.
Presurgical anxiety and acute postsurgical pain predict worse chronic pain profiles after total knee/hip arthroplasty.

Life and Health Sciences Research Institute (ICVS), School of Medicine, University of Minho, Campus de Gualtar, Braga, 4710-057, Portugal.
Introduction: Total joint arthroplasties generally achieve good outcomes, but chronic pain and disability are a significant burden after these interventions. Acknowledging relevant risk factors can inform preventive strategies. This study aimed to identify chronic pain profiles 6 months after arthroplasty using the ICD-11 (International Classification of Diseases) classification and to find pre and postsurgical predictors of these profiles.

Introduction: There is a lack of clinical evidence supporting the decision-making process between high tibial osteotomy (HTO) and unicomparmental knee arthroplasty (UKA) in gray zone indication, such as moderate medial osteoarthritis with moderate varus alignment. This study compared the outcomes between HTO and UKA in such cases and assessed the risk factor for not maintaining clinical improvements.
Materials And Methods: We retrospectively reviewed 65 opening-wedge HTOs and 55 UKAs with moderate medial osteoarthritis (Kellgren-Lawrence grade ≥ 3 and Ahlback grade < 3) and moderate varus alignment (5°< Hip-Knee-Ankle angle < 10°) over 3 years follow-up.
