    Abstract: Purpose: The incidence of distal radius fractures (DRFs) in the United States is more than 640,000 cases per year and is projected to increase. The overall prevalence of anemia in the United States increased from 5.71% in 2005 to 6.86% in 2018. ... ...

    Abstract Purpose: The incidence of distal radius fractures (DRFs) in the United States is more than 640,000 cases per year and is projected to increase. The overall prevalence of anemia in the United States increased from 5.71% in 2005 to 6.86% in 2018. Therefore, preoperative anemia may be an important risk factor to consider before surgical fixation of a distal radius fracture. The purpose of this study was to investigate preoperative anemia and its association with short-term complications after surgical treatment of DRFs.
    Methods: The American College of Surgeons National Surgical Quality Improvement Program database was queried for all patients who underwent open reduction internal fixation (ORIF) of DRFs between 2015 and 2020. The initial pool of patients was divided into cohorts based on preoperative hematocrit. Multivariate logistic regression, adjusted for all significantly associated patient demographics and comorbidities, was used to identify associations between preoperative anemia and postoperative complications after ORIF of DRFs.
    Results: A total of 22,923 patients who underwent ORIF of DRFs were identified in National Surgical Quality Improvement Program from 2015 to 2020. Of the 12,068 patients remaining after exclusion criteria, 9,616 (79.7%) patients were included in the normal cohort, 2,238 (18.5%) patients were included in the mild anemia cohort, and 214 (1.8%) patients were included in the severe anemia cohort. Compared with the reference cohort, patients with any anemia were independently associated with higher rates of reintubation (odds ratio [OR], 6.51; 95% confidence interval [CI], 1.29-32.80;
    Conclusions: Preoperative anemia, both mild and severe, were clinically significant predictors for postoperative complications within 30-day after ORIF of DRFs. Severe anemia was associated with higher rates of blood transfusion, nonhome discharge, and mortality compared with mild anemia.
    Type of study/level of evidence: Prognostic III.

    Abstract One-anastomosis gastric bypass (OAGB) is an effective procedure to treat severe obesity. However, conversion to Roux-en-Y gastric bypass (RYGB) is increasing. We therefore conducted a systematic review to determine the safety and efficacy associated with OAGB-RYGB conversion. A systematic search was conducted by three independent reviewers using Medline, Embase, and the Cochrane library following PRISMA guidelines. Six studies including 134 patients were selected who were undergoing OAGB-RYGB conversion. The most common indications were reflux (47.8%), malnutrition (31.3%), and inadequate weight loss (8.2%). Study outcomes demonstrated 100% resolution of bile reflux. Overall, there was medium-term weight gain of 0.61 BMI. OAGB to RYGB conversion leads to resolution of reflux symptoms. However, it is associated with weight regain, albeit this may be acceptable to patients to treat biliary reflux.

    Abstract Internal hernias are a worrying complication from laparoscopic Roux-en-Y gastric bypass (LRGB), with potential small bowel necrosis and obstruction. An electronic database search of Medline, Embase, and Pubmed was performed. All studies investigating the internal hernia rates in patients whose mesenteric defects were closed vs. not closed during LRGB were analysed. Odds ratios were calculated to assess the difference in internal hernia rate. A total of 14 studies totalling 20,553 patients undergoing LRGB were included. Internal hernia rate (220/12,445 (2%) closure vs. 509/8108 (6%) non-closure) and re-operation for small bowel obstruction (86/5437 (2%) closed vs. 300/3132 (10%) non-closure) were reduced when defects were closed. There was no difference observed when sutures were used to close the defects compared to clips/staples.

    Abstract Background: The purpose of this study was to investigate the association between preoperative platelet count and 30-day postoperative complications following arthroscopic rotator cuff repair (aRCR).
    Methods: The American College of Surgeons National Surgical Quality Improvement database was queried for all patients who underwent aRCR between 2015 and 2021. The study population was divided into 5 groups based on preoperative platelet count: normal (200-450k, reference cohort), low-normal (150-200k), mild thrombocytopenia (100-150k), moderate-to-severe thrombocytopenia (<100k), and thrombocytosis (>450k). Thirty-day postoperative complications following aRCR were collected. Multivariate logistic regression analysis was conducted to investigate the relationship between preoperative platelet counts and postoperative complications.
    Results: 24,779 patients were included in this study: 18,697 (75.5%) in the normal group, 4730 (19.1%) in the low-normal group, 1012 (4.1%) in the mild thrombocytopenia group, 171 (0.7%) in the moderate-to-severe thrombocytopenia group, and 169 (0.7%) in the thrombocytosis group. Low-normal platelets were an independent predictor of urinary tract infection (odds ratio [OR] 2.06, 95% confidence interval [CI] 1.12-3.77;
    Conclusion: Abnormal preoperative platelet counts, both low and high, were independent risk factors for 30-day postoperative complications following aRCR.

    Abstract Background: Rotator cuff tears are a common injury encountered by orthopedic surgeons. Reverse shoulder arthroplasty (RSA) has become a treatment option for those with acute tears, as well as those with prior failed rotator cuff repair (RCR). The objective of this study was to determine if there are differences in postoperative outcomes for patients with previous RCR compared to those undergoing primary RSA for rotator cuff tears.
    Methods: A comprehensive literature search was conducted using PubMed, EMBASE, Scopus, and Cochrane Library databases. All relevant studies were reviewed by two authors according to inclusion and exclusion criteria defined in the study. Demographics and postoperative outcomes including functional scores, range of motion, pain scores, and complications were recorded.
    Results: Six level III articles encompassing 2176 shoulders were included in the analysis (846 with previous RCR and 1330 without). Average postoperative American Shoulder and Elbow Surgeons scores were 75.41 in the prior RCR group and 81.61 in the group without prior repair (mean difference [MD] = -5.95,
    Conclusion: Patients with prior RCR undergoing RSA have worse postoperative functional scores and pain scores than those without prior RCR. However, these differences are below the minimal clinically important difference for each outcome.

    Abstract Background: The purpose of this study was to investigate the association between in-hospital length of stay (LOS) and postoperative complication rates within 30 days of total shoulder arthroplasty (TSA).
    Methods: All patients who underwent either anatomic or reverse TSA between 2015 and 2019 were queried from the American College of Surgeons National Surgical Quality Improvement database. The study population was stratified into three cohorts as follows: LOS 0 (same-day discharge), LOS 1 (next-day discharge), and LOS 2-3 (LOS of 2-3 days). Patient demographics and comorbidities were compared between cohorts using bivariate analysis. Multivariate logistic regression analysis was conducted to investigate the relationship between LOS and postoperative complications.
    Results: In comparison to the LOS 0 day cohort, LOS 2-3 day cohort had a greater likelihood of developing overall complication (OR, 2.598;
    Conclusion: Patients who were discharged on the same and next day following TSA demonstrated a reduced probability of experiencing respiratory complications, infections, postoperative anemia requiring transfusion, non-home discharge, and readmission in comparison to those with a LOS of 2-3 days. There was no difference in postoperative complications between same and nextday discharged patients. Patients who underwent outpatient arthroplasty were healthier at baseline compared to those who underwent inpatient arthroplasty.

    Abstract Preoperative oesophagogastroduodenoscopy (OGD) in bariatric surgery remains a controversial topic, with a large variety in practice globally. An electronic database search of Medline, Embase and PubMed was performed in an aim to categorise the findings of preoperative endoscopies in bariatric patients. A total of 47 studies were included in this meta-analysis resulting in 23,368 patients being assessed. Of patients assessed, 40.8% were found to have no novel findings, 39.7% had novel findings which did not affect surgical planning, 19.8% had findings that affected their surgery and 0.3% were ruled to not be suitable for bariatric surgery. Preoperative OGD is altering surgical planning in one-fifth of patients; however, further comparative studies are required to determine if each patient should undergo this procedure especially if asymptomatic.
