Evaluating the impact of metabolic surgery on patients with prior opioid use.

Metabolic surgery is the most effective treatment for obesity and may improve obesity-related pain syndromes. However, the effect of surgery on the persistent use of opioids in patients with a history of prior opioid use remains unclear. To determine the effect of metabolic surgery on opioid use behaviors in patients with prior opioid use. A consortium of public and private hospitals in Michigan. Using a statewide metabolic-specific data registry, we identified 16,820 patients who self-reported opioid use before undergoing metabolic surgery between 2006 and 2020 and analyzed the 8506 (50.6%) patients who responded to 1-year follow-up. We compared patient characteristics, risk-adjusted 30-day postoperative outcomes, and weight loss between patients who self-reported discontinuing opioid use 1 year after surgery and those who did not. Among patients who self-reported using opioids before metabolic surgery, 3864 (45.4%) discontinued use 1 year after surgery. Predictors of persistent opioid use included an annual income of <$10,000 (odds ratio [OR] = 1.24; 95% confidence interval [CI], 1.06-1.44; P = .006), Medicare insurance (OR = 1.48; 95% CI, 1.32-1.66; P < .0001), and preoperative tobacco use (OR = 1.36; 95% CI, 1.16-1.59; P = .0001). Patients with persistent use were more likely to have a surgical complication (9.6% versus 7.5%, P = .0328) and less percent excess weight loss (61.6% versus 64.4%, P < .0001) than patients who discontinued opioids after surgery. There were no differences in the morphine milligram equivalents prescribed within the first 30 days following surgery between groups (122.3 versus 126.5, P = .3181). Nearly half of patients who reported taking opioids before metabolic surgery discontinued use at 1 year. Targeted interventions aimed at high-risk patients may increase the number of patients who discontinue opioid use after metabolic surgery.

Exploring Olfactory Dysfunction as a Marker of Frailty and Postoperative Outcomes in Head and Neck Cancer

Olfactory dysfunction (OD) is increasingly recognized as a robust marker of frailty and mortality. Despite broad recognition of frailty as a critical component of head and neck cancer (HNC) care, there is no standardized frailty assessment. To assess the prevalence of OD and its association with frailty and postoperative outcomes in HNC. In this prospective cohort study with enrollment between February 17, 2021, to September 29, 2021, at a tertiary academic medical center, 85 eligible adult patients with primary, treatment-naive HNC of mucosal or cutaneous origin were included. Patients with a history of COVID-19, neurocognitive, or primary smell/taste disorders were excluded. Prospective olfactory assessments (self-reported, visual analog scale [VAS] and psychophysical, University of Pennsylvania Smell Identification Test [UPSIT]) with concurrent frailty assessment (Risk Analysis Index [RAI]) were used. Olfactory-specific quality of life (QOL) was examined with brief Questionnaire of Olfactory Disorders-Negative Statements (QOD-NS). The primary outcome was the prevalence of OD as assessed by VAS (0-10, no to normal smell) and UPSIT (0-40, higher scores reflect better olfaction) and its association with frailty (RAI, 0-81, higher scores indicate greater frailty). For surgical patients, secondary outcomes were associations between OD and postoperative length of stay (LOS), 30-day postoperative outcomes, and QOD-NS (0-21, higher scores indicate worse QOL). Among 51 patients with HNC (mean [SD] age, 63 [10] years; 39 [77%] male participants; 41 [80%] White participants), 24 (47%) were frail, and 4 (8%) were very frail. Despite median (IQR) self-reported olfaction by VAS of 9 (8-10), 30 (59%) patients demonstrated measured OD with psychophysical testing. No meaningful association was found between self-reported and psychophysical testing (Hodges-Lehmann, <0.001; 95% CI, -2 to 1); a total of 46 (90%) patients did not report decreased olfaction-specific QOL. Median UPSIT scores were lower in frail patients (Hodges-Lehmann, 6; 95% CI, 2-12). Multivariate modeling demonstrated severe microsmia/anosmia was associated with 1.75 (95% CI, 1.09-2.80) times odds of being frail/very frail and approximately 3 days increased LOS (β, 2.96; 95% CI, 0.29-5.62). Although patients with HNC are unaware of olfactory changes, OD is common and may serve as a bellwether of frailty. In this prospective cohort study, a dose-dependent association was demonstrated between increasing degrees of OD and frailty, and the potential utility of olfaction was highlighted as a touchstone in the assessment of HNC frailty.

Emergency thoracic surgery patients have worse risk-adjusted outcomes than non-emergency patients

BackgroundOutcomes for patients undergoing emergency thoracic operations have not been well described. This study was designed to compare postoperative outcomes among patients undergoing emergency versus nonemergency thoracic operations. MethodsWe retrospectively analyzed the American College of Surgeons National Surgical Quality Improvement Program database (2005–2018). We identified patients who underwent emergency thoracic operations using current procedural technology codes. Patients were then sorted into 1 of 4 cohorts: lung and chest wall, hiatal hernia, esophagus, and pericardium. Emergency versus nonemergency outcomes were compared. Univariate logistic regression was performed with “emergency status” as the independent variable and 30-day postoperative outcomes as the dependent variables. Multiple logistic regression models were performed to control for preoperative factors. ResultsOf 90,398 thoracic operations analyzed, 4,044 (4.5%) were emergency. Common emergency operations were pericardial window (n = 580, 10.2%), laparoscopic hiatal hernia repair (n = 366, 8.9%), thoracoscopic partial lung decortication (n = 334, 8.1%), thoracoscopic wedge resection (n = 301, 7.3%), thoracoscopic total lung decortication (n = 256, 6.2%), and open repair of hiatal hernia without mesh (n = 254, 6.2%). In all 4 cohorts, 30-day postoperative complications occurred more frequently after emergency surgery. After controlling for patient characteristics, 8 complications were more frequent after emergency lung and chest wall surgery, 5 complications were more frequent after emergency hiatal hernia surgery, and 3 complications were more frequent after emergency pericardium surgery. Risk-adjusted complications were not different after emergency esophageal surgery. ConclusionPatients undergoing emergency thoracic operations have worse risk-adjusted outcomes than those undergoing nonemergency thoracic operations. Subset analysis is needed to determine what factors contribute to increased adverse outcomes in specific patient populations.

The Role of Diversion During Ileal Pouch Anal Anastomosis (IPAA) Creation in Pediatric Ulcerative Colitis

IntroductionIn pediatric ulcerative colitis (UC), surgery is often postponed until disease is life-threatening or refractory to immune suppression. In these settings, diverting ileostomy (DI) is theorized to have a protective effect on the new anastomosis. However, analyses have been performed only in single-institution series and the true impact of performing DI at the time of IPAA on postoperative outcomes is unclear. MethodsWe performed a retrospective cohort study using claims data from the International Business Machines (IBM) MarketScan® database. Patients were sorted to the DI group if they carried a CPT code for ostomy closure within 6 months of index procedure. We examined demographics, preoperative risk factors, and performed regression analysis to compare 30-day postoperative outcomes between groups. ResultsWe identified 317 patients ≤18yo that underwent IPAA procedure and met inclusion criteria from 2000 to 2019. Of these, 238 patients were assigned to the IPAA + DI cohort and 79 patients were assigned to the IPAA cohort.Adverse outcomes were comparable between cohorts. Surgical site infection (SSI) rates between IPAA and IPAA + DI were 10.1 vs. 11.3% (p = 0.67). Rates of intra-abdominal drainage procedures were 3.8 vs. 2.1% (p = 0.39). The rates of 30-day readmissions were 16.5 vs. 19.3% (p = 0.39). Creation of a DI was not associated with higher odds of 30-day readmission (OR = 1.4, p = 0.31). ConclusionCreating a DI necessitates an additional surgery for closure and is not associated with decreased adverse outcomes. There is still a role for multicenter studies to define which patient populations may benefit from diversion. Level of EvidenceRetrospective comparative study. Type of StudyLevel III.

Resident Involvement in Shoulder-Stabilization Procedures Is Not Associated With an Increased Risk of 30-Day Postoperative Complications

To examine the 30-day postoperative outcomes of resident involvement in shoulder-stabilization surgical procedures using the American College of Surgeons National Surgical Quality Improvement database. We conducted a retrospective review of the National Surgical Quality Improvement database for all shoulder-stabilization procedures from 2010 to 2018. Procedures included arthroscopic Bankart, arthroscopic Bankart with SLAP repair, arthroscopic Bankart with Remplissage, open Bankart, anterior bone block, posterior bone block, Latarjet coracoid process transfer, and capsular shift/capsulorrhaphy for multidirectional instability. Data included preoperative demographics, comorbidities, and 30-day postoperative outcomes. Cases were categorized into 2 groups: "attending alone" and "attending and resident." Statistical analysis comparing groups on demographics and comorbidities included independent t-test for continuous variables and Pearson χ2 or Fischer exact for categorical variables. A logistic regression model including propensity score was used to calculate adjusted odds ratio for outcomes. A total of 3,954 patients undergoing shoulder-stabilization procedures were included in the study and 28.8% of patients had a resident involved intheir procedure. Residents were more likely to be involved in procedure for patients who were of minority ethnicity (P<.001), a lower body mass index (P < .001) and less likely to have a history of chronic obstructive pulmonary disease (P= .029). Resident involvement resulted in statistically significant longer total operation time (91 vs 85 minutes, P < .001). In terms of postsurgical outcomes, complication rates were low for both groups (∼0.8%). Resident involvement was not associated with any significant increase in 30-day postsurgical complications. Our results show that resident involvement in shoulder-stabilization surgery is associated with a significant increase in operative time without any significant increase in 30-day postsurgical complications. Level III, retrospective comparative study.

Thirty day postoperative outcomes following laparoscopic adrenalectomy for functional adrenal tumors.

Functional adrenal tumors (FATs) are rare and if left untreated, there is a substantial risk of morbidity and mortality due to uncontrolled excess hormone secretion. The three most common FATs are cortisone-producing tumors (hypercortisolism), aldosterone-producing tumors (hyperaldosteronism), and catecholamines-producing tumors (pheochromocytomas). The study aims to evaluate demographic characteristics and 30-day outcomes after laparoscopic adrenalectomy of FATs. Patients who underwent laparoscopic adrenalectomy for FATs were selected from the ACS-NSQIP database (2015-2017), and divided into three groups (hyperaldosteronism, hypercortisolism, and pheochromocytoma). Preoperative demographics, medical comorbidities, and 30-day postoperative outcomes among the three groups were analyzed using the chi-squared test, analysis of variance (ANOVA) and Kruskal-Wallis one-way analysis of variance. Multivariable logistic regression was performed to assess the effects independent variables on the likelihood of increased overall morbidity. Of a total of 2410 patients who underwent laparoscopic adrenalectomy, 345 (14.3%) patients with FATs were included. Patients in the hypercortisolism group were younger, had higher proportion of females, had higher BMI, had a higher proportion of White ethnicity and had a higher proportion of diabetes. The hyperaldosteronism group had a higher proportion of Black ethnicity and a higher proportion of hypertension (HTN) requiring medication. Thirty day postoperative outcomes showed that the pheochromocytoma group had a higher rate of serious morbidity, overall morbidity, and highest readmission rates. There were three deaths, 1 in the pheochromocytoma and 2 in the hypercortisolism groups. Operative time (in minutes) was longer in the hypercortisolism group. Median length of stay was higher in hypercortisolism (2days) and pheochromocytoma (1.5day) groups. Functional adrenal tumors show distinct variations in patient demographics and postoperative outcomes. It is essential to use this information during the preoperative period to optimize patients prior to intervention and counsel patients about potential postoperative outcomes.

A 13-year experience with biologic and biosynthetic absorbable mesh reinforced laparoscopic paraesophageal hernia repair.

Mesh reinforced cruroplasty during laparoscopic paraesophageal hernia repair remains controversial due to wide variation in surgical technique and mesh composition. This study aims to review outcomes and rates of recurrence following laparoscopic paraesophageal hernia repair (LPEHR) with mesh reinforced cruroplasty utilizing absorbable mesh at a single institution. A retrospective review of all patients who underwent LPEHR with mesh was performed. Medical records were reviewed for patient reported, radiographic or endoscopic evidence of recurrence, defined as > 2cm of vertical intrathoracic stomach. If no studies were available for review, patients were considered to have no recurrence. Outcomes and mesh-related complications were also reviewed. Between 10/2008 and 9/2021, 473 patients underwent LPEHR with absorbable mesh; 1.3% type 2 hernias, 86.0% type 3 hernias, 12.7% type 4 hernias. Three types of mesh were used: initially biologic mesh (n = 83), then heavyweight synthetic bioabsorbable mesh (n = 261), and finally lightweight synthetic bioabsorbable mesh (n = 111). There were no significant differences in age, ASA, BMI, gender, smoking status, chronic steroid use, preoperative acid suppression, hernia type, or recurrent hernia between groups. There were no significant differences in 30-day postoperative outcomes. Reflux Symptom Index, GERD-HRQL, and Dysphagia Scores at 1- and 2-year postoperative timepoints were not significantly different. The overall recurrence rate was 16.7%, with no significant differences in recurrence rates between biologic, heavyweight or lightweight biosynthetic absorbable mesh through 2 years after surgery. A shorter median time to recurrence (10months, p = 0.016) was seen in the lightweight group. LPEHR with absorbable mesh reinforced cruroplasty is feasible and safe, with equivalent patient-reported outcomes, including dysphagia, up to 2-years postop regardless of mesh choice. No significant differences in recurrence rates between biologic, heavyweight, or lightweight synthetic bioabsorbable mesh were seen up to 2 years after LPEHR.

Comparative outcomes of bariatric surgery in patients with ESRD on dialysis in the modern era of renal transplantation: analysis using the 2015-2020 MBSAQIP database.

Severe obesity is a relative contraindication for renal transplantation, therefore bariatric surgery is an important option as a pre-kidney transplant weight loss strategy. However, comparative data regarding postoperative outcomes of laparoscopic sleeve gastrectomy (LSG) or laparoscopic Roux-en-Y gastric bypass (LRYGB) in patients with or without ESRD on dialysis are scarce. Patients between 18- and 80-year-old who underwent LSG and RYGB were included. To determine the outcomes of patient who underwent bariatric surgery with ESRD on dialysis, a 1:4 PSM was performed between the patients with ESRD on dialysis and those without renal disease. The PSM analyses in both groups were performed using 20 preoperative characteristics. Then 30-day postoperative outcomes were assessed. The operative time and postoperative-LOS were significantly longer in ESRD patients on dialysis compared to those with no renal disease either for LSG (82.37 ± 40.42 vs. 73.62 ± 38.65; P < 0.001, 2.22 ± 3.01 vs. 1.67 ± 1.90; P < 0.001) or for LRYGB (129.13 ± 63.20 vs. 118.72 ± 54.16; P = 0.002, 2.53 ± 1.74 vs. 2.00 ± 1.68; P < 0.001). In the LSG cohort (2137 vs. 8495 matched cases), patients with ESRD on dialysis showed significant increase in mortality (0.7% vs 0.3%; P = 0.019), unplanned ICU admission (3.1% vs 1.3%; P < 0.001), blood transfusions (2.3% vs 0.8%; P 0.001), readmissions (9.1% vs. 4.0%; P < 0.001), reoperations (3.4% vs. 1.2%; P < 0.001), interventions (2.3% vs. 1.0%; P = 0.006). In the LRYGB group (443 vs. 1769 matched cases), patients with ESRD on dialysis showed a significantly higher need for unplanned ICU admission (3.8% vs. 1.4%; P = 0.027), readmissions (12.4% vs. 6.6%; P = 0.011), and interventions (5.2% vs. 2.0%; P = 0.050). Bariatric surgery is a safe procedure for patients with ESRD on dialysis to help them get a kidney transplant. Even though this group experienced a higher incidence of postoperative complications compared to those without kidney disease, the absolute complication rates are low and not associated with bariatric-specific complications. Therefore, ESRD should not be perceived as contraindications to bariatric surgery.

Is High Body Mass Index Protective or Detrimental in Surgical Fixation of Hip Fractures?: A Spline Regression Analysis of 22,388 Patients.

We aimed to characterize the association between BMI as a continuous variable and 30-day postoperative outcomes following hip fracture surgery through:1)30-day readmission and reoperation; 2)local wound-related; and 3)systemic complications. The National Surgical Quality Improvement Program(NSQIP) database(January 2016-December,2019) was queried for patients undergoing hip fracture ORIF. Baseline patient demographics, comorbidities, and patient outcomes were recorded. Multivariable regression models accounted for baseline demographics, comorbidities, and fracture patterns. Significant associations were analyzed using spline regression models to evaluate the continuous association between BMI and the aforementioned outcomes. Spline models demonstrated a U-shaped curve for the odds of 30-day readmission and 30-day reoperation with nadirs at the BMI of 27.5Kg/m2 and 22.0Kg/m2. The odd ratios of superficial infection, deep infection, any wound complication, and inability to weight bear on POD 1 rose progressively starting at a BMI of 25.6Kg/m2, 35.5Kg/m2, 25.6Kg/m2, and 32.7Kg/m2 respectively. Odds of 30-day mortality, transfusion, pneumonia, and delirium were greatest at the lowest recorded BMI (11.9Kg/m2). BMI has a U-shaped association with 30-day readmission and reoperation. Conversely, the highest risk of mortality and systemic complications (transfusion, pneumonia, and delirium) were within the lower BMI range, with diminishing risk as BMI increased. Local wound complications and systemic sepsis exhibited a third unique pattern with progressive rise in odds as BMI increased. The odds of any-complications demonstrated a U-shaped pattern with a nadir in the overweight to obese I categories, suggesting patients may be at lowest risk within this range. Therapeutic Level III.

Artificial Intelligence versus Surgeon Gestalt in Predicting Risk of Emergency General Surgery.

Artificial Intelligence (AI) risk prediction algorithms such as the smartphone-available POTTER for emergency general surgery (EGS) are superior to traditional risk calculators because they account for complex nonlinear interactions between variables, but how they compare to surgeons' gestalt remains unknown. Herein, we sought to: (1) compare POTTER to surgeons' surgical risk estimation and (2) assess how POTTER influences surgeons' risk estimation. A total of 150 patients who underwent EGS at a large quaternary care center between May 2018 and May 2019 were prospectively followed for 30-day postoperative outcomes (mortality, septic shock, ventilator dependence, bleeding requiring transfusion, pneumonia), and clinical cases were systematically created representing their initial presentation. POTTER's outcome predictions for each case were also recorded. Thirty acute care surgeons with diverse practice settings and levels of experience were then randomized into 2 groups: 15 surgeons (SURG) were asked to predict the outcomes without access to POTTER's predictions while the remaining 15 (SURG-POTTER) were asked to predict the same outcomes after interacting with POTTER. Comparing to actual patient outcomes, the Area Under the Curve (AUC) methodology was used to assess the predictive performance of 1) POTTER vs. SURG, and 2) SURG vs. SURG-POTTER. POTTER outperformed SURG in predicting all outcomes (mortality - AUC: 0.880 vs. 0.841; ventilator dependence - AUC: 0.928 vs. 0.833; bleeding - AUC: 0.832 vs. 0.735; pneumonia - AUC: 0.837 vs. 0.753) except septic shock (AUC: 0.816 vs 0.820). SURG-POTTER outperformed SURG in predicting mortality (AUC: 0.870 vs 0.841), bleeding (AUC: 0.811 vs 0.735), pneumonia (AUC: 0.803 vs 0.753) but not septic shock (AUC: 0.712 vs 0.820) or ventilator dependence (AUC: 0.834 vs 0.833). The AI risk calculator POTTER outperformed surgeons' gestalt in predicting the postoperative mortality and outcomes of EGS patients, and when used, improved the individual surgeons' risk prediction. AI algorithms such as POTTER could prove useful as a bedside adjunct to surgeons when preoperatively counselling patients. Level II, Prognostic/Epidemiological.

Chronic steroid use as a risk factor for postoperative complications following arthroscopic rotator cuff repair

Steroids are a common treatment for many rheumatologic and inflammatory disorders. Chronic steroid use has been studied in joint arthroplasty and arthroscopy, but studies specifically on preoperative chronic steroid use in arthroscopic rotator cuff repair (aRCR) are limited. The purpose of this study is to determine the association between chronic steroid use and 30-day postoperative outcomes following aRCR. The American College of Surgeons National Surgical Quality Improvement Program (NSQIP) was queried to identify all patients who underwent aRCR between 2015 and 2020. Patients were divided into 2 cohorts: nonsteroid users and chronic steroid users. Univariate binomial regression analysis was used to compare demographics, comorbidities, and postoperative outcomes between cohorts. Multivariate regression analysis, adjusted for all significant demographics and comorbidities, was used to identify significant 30-day postoperative outcomes. A total of 39,876 patients remained after exclusion criteria, with 39,068 (97.97%) in the nonsteroid group and 808 (2.02%) in the chronic steroid group. Patient demographics and comorbidities significantly associated with chronic steroid use were age ≥65 (P<.001), female gender (P<.001), body mass index (BMI) ≥35, American Society of Anesthesiologists (ASA) ≥3 (P<.001), dependent functional status (P<.001), nonsmokers (P=.046), higher rates of dyspnea (P<.001), chronic obstructive pulmonary disease (COPD) (P<.001), congestive heart failure (P<.001), hypertension requiring medication (P<.001), open wound infection (P=.018), unintentional weight loss (P<.001), bleeding disorders (P<.001), and inpatient procedure (P=.013). Multivariate analysis found preoperative chronic steroid use to be an independent predictor of mortality within 30 days following aRCR (OR 8.15, confidence interval (CI) 1.45-45.86; P=.017). Chronic steroid use was not found to be an independent risk factor for infection, readmission, or reoperation following aRCR. It was, however, found to be independently associated with higher rates of 30-day mortality following aRCR, although with a limited overall number of deaths reported.

Metabolic Syndrome: Is Arthroscopic Rotator Cuff Repair Safe in This Patient Population?

Purpose Metabolic syndrome is associated with postoperative morbidity and mortality in surgical patients. With the increased use of arthroscopic techniques for rotator cuff repair (RCR), it is important to identify the impact this disorder has on surgical patients. The purpose of this study is to evaluate the clinical impact of metabolic syndrome on outcomes following arthroscopic RCR. Methods The 2006-2019 National Surgical Quality Improvement Program database was queried for adult patients who underwent arthroscopic RCR. Two patient groups were categorized: patients with metabolic syndrome and patients without metabolic syndrome. Demographics, comorbidities, and 30-day postoperative outcomes were compared using bivariate and multivariate analyses. Results Of 40,156 patients undergoing arthroscopic RCR, 36,391 did not have metabolic syndrome and 3,765 had metabolic syndrome. After adjusting for differences in baseline characteristics between the two groups, those with metabolic syndrome had an increased risk of developing renal complications and cardiac complications, as well as requiring hospital admission postoperatively and hospital readmission. Conclusion Metabolic syndrome is an independent risk factor for developing renal and cardiac complications, as well as requiring overnight hospital admission and hospital readmission. Providers should understand the need for preoperative evaluation and surveillance of these patients following their surgery to minimize the risk of poor outcomes.

Racial Disparities in Short-Stay and Outpatient Total Hip and Knee Arthroplasty: 13-year Trend in Utilization Rates and Perioperative Morbidity Using a National Database.

The objective of this study was to assess racial and ethnic disparities in short-stay (< 2-midnight length of stay) and outpatient (same-day discharge) total joint arthroplasties (TJAs). We aimed to determine (1) whether there are differences in postoperative outcomes between short-stay Black, Hispanic, and White patients and (2) the trend in utilization rates of short-stay and outpatient TJA across these racial groups. This was a retrospective cohort study of the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP). Short-stay TJAs done between 2008 and 2020 were identified. Patient demographics, comorbidities, and 30-day postoperative outcomes were assessed. Multivariate regression analysis was used to assess differences between racial groups in minor and major complication rates, as well as readmission and revision surgery rates. Of a total of 191,315 patients, 88% were White, 8.3% were Black, and 3.9% were Hispanic. Minority patients were younger and had greater comorbidity burden when compared with Whites. Black patients had greater rates of transfusions and wound dehiscence when compared with White and Hispanic patients ( P < 0.001, P = 0.019, respectively). Black patients had lower adjusted odds of minor complications (odds ratio [OR], 0.87; confidence interval [CI], 0.78 to 0.98), and minorities had lower revision surgery rates in comparison with Whites (OR, 0.70; CI, 0.53 to 0.92, and OR, 0.84; CI, 0.71 to 0.99, respectively). The utilization rate for short-stay TJA was most pronounced for Whites. There continues to persist marked racial disparities in demographic characteristics and comorbidity burden in minority patients undergoing short-stay and outpatient TJA procedures. As outpatient-based TJA becomes more routine, opportunities to address these racial disparities will become increasingly more important to optimize social determinants of health. III, retrospective cohort study.

What Is the Effect of Resident Involvement on Short-Term Outcomes after Distal Radius Fracture Surgery?

Background: The objective of this study was to assess whether resident involvement in distal radius fracture open reduction internal fixation (ORIF) affect 30-day postoperative complication, hospital readmission, reoperation and operative time. Methods: A retrospective study was performed using the American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) database by querying the Current Procedural Terminology (CPT) codes for distal radius fracture ORIF from 1 January 2011 to 31 December 2014. A final cohort of 5,693 adult patients who underwent distal radius fracture ORIF during the study period were included. Baseline patient demographics and comorbidities, intraoperative factors, including operative time and 30-day postoperative outcomes, including complications, readmission and reoperations, were collected. Bivariate statistical analyses were performed to identify variable associated with complication, readmission, reoperation and operative time. The significance level was adjusted using a Bonferroni correction as multiple comparisons were performed. Results: In this study of 5,693 patients who underwent distal radius fracture ORIF, 66 patients had a complication, 85 patients were readmitted and 61 patients underwent reoperation within 30 days of surgery. Resident involvement in the surgery was not associated with 30-day postoperative complication, readmission or reoperation, but was associated with longer operative time. Moreover, 30-day postoperative complication was associated with older age, American Society of Anesthesiologists (ASA) classification, chronic obstructive pulmonary disease (COPD), congestive heart failure (CHF), hypertension and bleeding disorder. Thirty-day readmission was associated with older age, ASA classification, diabetes mellitus, COPD, hypertension, bleeding disorder and functional status. Thirty-day reoperation was associated with higher body mass index (BMI). Longer operative time was associated with younger age, male sex and the absence of bleeding disorder. Conclusions: Resident involvement in distal radius fracture ORIF is associated with longer operative time, but no difference in rates of episode-of-care adverse events. Patients may be reassured that resident involvement in distal radius fracture ORIF does not negatively impact short-term outcomes. Level of Evidence: Level IV (Therapeutic).

Did the centers for medicare &amp; medicaid services’ 2018 policy change removing total knee arthroplasty from the inpatient-only list affect overall patient outcomes in the medicare population?

Background: The 2018 Centers for Medicare &amp; Medicaid Services (CMS) removal of total knee arthroplasty (TKA) from the Inpatient-Only (IPO) list was accompanied by confusion, lack of central guidance on patient selection criteria, payor misinterpretation of the updated policy, and altered payor incentives. The purpose of this study was to assess how the CMS policy change affected overall patient outcomes in the Medicare population after TKA. Methods: Using the ACS-NSQIP database, patients 65 years and older who underwent primary, elective, unilateral TKA without any significant medical comorbidity were included. Complication rates before (2014-2017) and after (2018-2019) CMS removal of TKA from the IPO list were compared using interrupted time series analysis to gauge the impact of the policy shift. Results: A total 185,294 TKA cases were included in the analysis. Following the CMS removal of TKA from the IPO list in 2018, there were significant decreases in rates of any adverse event (RR 0.90, 95% CI 0.83-0.98, P=0.02), any minor adverse event (RR 0.84, 95% CI 0.73-0.97, P=0.02), and thromboembolic events (RR 0.76, 95% CI 0.64-0.89, P&lt;0.001) significantly decreased There were no significant changes in rates of readmission (RR 0.95, 95% CI 0.87-1.05, P=0.31), reoperation (RR 0.92, 95% CI 0.78-1.09, P=0.33), or any major adverse event (RR 0.92, 95% CI 0.83-1.01, P=0.07). Conclusions: Though the CMS removal of TKA from the IPO list in 2018 was accompanied by the emergence of key new issues, the policy change did not adversely affect 30-day postoperative outcomes in the Medicare TKA patient population. Level of Evidence: Level IV—retrospective cohort study.

Review of long-term complications and functional outcomes of ileoanal pouch procedures in patients with inflammatory bowel disease.

In medically refractory Ulcerative Colitis (UC), proctocolectomy with ileoanal pouch procedure (IAPP) is the preferred continence-preserving surgical option. Functional outcomes post-surgery and long-term complication rates in the biologic era remain ambiguous. This review primarily aims to provide an update on these outcomes. Secondarily, risk factors associated with chronic pouchitis and pouch failure are explored. Two online databases (MEDLINE and EMBASE) were searched on 4 October 2022 for English studies from 2011-present relating to long-term outcomes of IAPP in inflammatory bowel disease (IBD) patients. Adult patients with 12 month follow-up were included. Studies focused on 30-day post-operative outcomes, non-IBD patients or studies including less than 30 patients were excluded. Following screening and full-text review of 1094 studies, 49 were included. Median sample size was n = 282 (IQR: 116-519). Median incidences for chronic pouchitis and pouch failure were 17.1% (IQR: 12-23.6%) and 6.9% (IQR: 4.8-10.8%), respectively. Upon multivariate analysis, chronic pouchitis development was most significantly associated with pre-operative steroid use, pancolitis and extra-intestinal IBD manifestations, whilst pouch failure was most significantly associated with pre-operative diagnosis of Crohn's disease (compared to UC), peri-operative pelvic sepsis and anastomotic leak. Overall patient satisfaction was very high with four included studies reporting greater than 90% satisfaction rates. Long-term complications for IAPP were common. However, despite this, patient satisfaction post-IAPP was high. Up-to-date knowledge of complication rates and their risk factors improves pre-operative counselling, management planning and patient outcomes.

Changing disposition patterns in the era of COVID-19 after colon resections: A National Surgical Quality Improvement Program colectomy study

BackgroundThe COVID-19 pandemic severely impacted post-hospitalization care facilities in the United States and hindered their ability to accept new patients for various reasons. This study aimed to assess the impact of the pandemic on discharge disposition after colon surgery and associated postoperative outcomes. MethodsA retrospective cohort study was performed using the National Surgical Quality Improvement Participant Use File and targeted colectomy. Patients were divided into the following 2 cohorts: (1) pre-pandemic (2017–2019) and (2) pandemic (2020). The primary outcomes included discharge disposition—post-hospitalization facility versus home. The secondary outcomes were rates of 30-day readmissions and other postoperative outcomes. The multivariable analysis assessed for confounders and effect modification on discharge to home. ResultsDischarge to posthospitalization facilities decreased by 30% in 2020 compared to 2017 to 2019 (7% vs 10%, P < .001). This occurred despite an increase in emergency cases (15% vs 13%, P < .001) and open surgical approach (32% vs 31%, P < .001) in 2020. Multivariable analysis revealed that patients in 2020 had 38% lower odds of going to post-hospitalization facilities (odds ratio 0.62, P < .001) after adjusting for surgical indications and underlying comorbidities. This decrease in patients going to a post-hospitalization facility was not associated with an increased length of stay or an increase in 30-day readmissions or postoperative complications. ConclusionDuring the pandemic, patients undergoing colonic resection were less likely to be discharged to a post-hospitalization facility. This shift was not associated with an increase in 30-day complications. This should prompt further research to assess the reproducibility of these associations, especially in a setting without a global pandemic.

A 5-year characterization of trends and outcomes in elderly patients undergoing elective bariatric surgery.

The North American population with severe obesity is aging and with that so will the number of elderly patients (≥ 65years) meeting indications for metabolic surgery. Trends in bariatric delivery in this population are poorly characterized and outcomes remain conflicting, limiting potential uptake and delivery. The MBSAQIP database was used to identify elderly patients (≥ 65years) undergoing elective bariatric surgery from 2015 to 2019. Our objectives were to analyze their unique characteristics, surgical operative trends, and outcomes by comparing to a non-elderly cohort. Multivariable logistic regression identified independent predictors of serious complications and 30-day mortality. There was a total of 751,607 patients, 5.3% (n = 39,854) were elderly. Mean ages were 43 ± 11years (non-elderly) versus 68 ± 3years (elderly). Elderly patients were less likely to be female (70.7% elderly; 80.1% non-elderly) and had lower BMI (43.17 ± 6.64kg/m2 elderly; 45.42 ± 7.87kg/m2 non-elderly). They had higher American Society of Anesthesiologists classification, lower functional status, more insulin dependent diabetes, and hypertension, among other comorbidities. There were no clinically significant differences between the most frequently performed bariatric surgery. Sleeve gastrectomy remained the most common (73.7% non-elderly; 72.3% elderly); however, operative time was longer among the elderly. Functional status was most predictive for both serious complications (OR 1.72; CI 1.53-1.94) and mortality (OR 2.92; CI 1.98-4.31). Surgery among elderly patients was associated with poorer 30-day postoperative outcomes across all categories and was independently associated with serious complications (OR 1.23; CI 1.17-1.30, p < 0.001; AR 4.64%) and 30-day mortality (OR 2.49; CI 2.00-3.11, p < 0.001; AR 0.27%), after adjusting for comorbidities. After adjusting for comorbidities, functional status remains the most predictive factor for poor outcomes; however, elderly patients have increased 30-day odds of serious complications and 30-day mortality, suggesting a need to tailor our approach to these individuals that carry a unique operative risk.

From transabdominal to totally extra-peritoneal robotic ventral hernia repair: observations and outcomes.

While robotic-assisted hernia repair has increased the popularity of minimally invasive hernia surgery, selecting between the types of approaches is a challenge for both experts and novices alike. In this study, we compared a single surgeon's early experience transitioning from transabdominal hernia repair with sublay mesh in either the pre-peritoneal or retrorectus space (TA-SM) and enhanced-view totally extra-peritoneal (eTEP) ventral hernia repair in the peri-operative and long-term post-operative time periods. We conducted a retrospective review of 50 eTEP and 108 TA-SM procedures to collect demographics, intraoperative details, and 30-day and 1-year post-operative outcomes. Statistical analysis was performed utilizing Chi-square analysis, Fisher's test, and two sample t-tests with equal variances. There were no significant differences in patient demographics or comorbidities. eTEP patients had larger defects (109.1 cm2 vs. 31.8 cm2, p = 0.043) and mesh used (432.8 cm2 vs. 137.9 cm2, p = 0.001). Operative times were equivalent (158.3 ± 90.6min eTEP and 155.8 ± 65.2min TA-SM, p = 0.84), but conversion to alternate procedure type was higher for the transabdominal approach (4% eTEP vs. 22% TA-SM, p < 0.05). Hospital stay was less in the eTEP cohort (1.3days vs. 2.2days, p < 0.05). Within 30 days, there were no significant differences in emergency visits or hospital readmissions. There was a greater propensity for eTEP patients to develop seromas (12.0% vs. 1.9%, p < 0.05). At 1 year, there was no statistically significant difference in recurrence rate (4.56% eTEP vs. 12.2% TA-SM, p = 0.28) respective to average time to recurrence (9.17months eTEP vs. 11.05months TA-SM). The eTEP approach can be adopted safely and efficiently, and may have superior peri-operative outcomes including fewer conversions and reduced hospital stay.
