GLIM criteria validation and reliability in critically ill patients with cancer: A prospective study.

The present study aims to assess the interrater reliability of the Global Leadership Initiative on Malnutrition (GLIM) criteria, a framework to provide a consensus diagnosis of malnutrition. We also aimed to investigate its concurrent and predictive validity in the context of patients with cancer admitted to the intensive care unit (ICU). Individuals aged ≥19 years with cancer who were admitted to the ICU within 48 h of their initial hospital admission were included. Nutrition status was assessed with the Nutritional Risk Screening 2002, the Subjective Global Assessment (SGA), and the GLIM criteria. Interrater reliability was assessed by the kappa test (>0.80). The SGA served as the established benchmark for assessing concurrent validity. To evaluate predictive validity, the occurrence of mortality within 30 days was the outcome, and Cox regression models were applied. A total of 212 patients were included: 66.9% were at nutrition risk, and 45.8% were malnourished according to the SGA. According to the GLIM criteria, 68.4% and 66% were identified as malnourished by evaluators 1 and 2, respectively (κ = 0.947; P < 0.001). The GLIM combination incorporating weight loss and the presence of inflammation exhibited sensitivity (82.4%) and specificity (92%). In the multivariate Cox regression models, most GLIM combinations emerged as independent predictors of complications. The GLIM criteria demonstrated satisfactory interrater reliability, and the combination involving weight loss and the presence of inflammation exhibited noteworthy sensitivity and specificity. Most GLIM combinations emerged as independent predictors of 30-day mortality.

Risk factors for complications following sacral neuromodulation for faecal incontinence: Long-term follow-up.

Sacral neuromodulation (SNM) has become a standard surgical treatment for faecal incontinence (FI). Prior studies have reported various adverse events of SNM, including suboptimal therapeutic response, infection, pain, haematoma, and potential need for redo SNM. The aim of this study was to identify the risk factors associated with long-term complications of SNM. This retrospective cohort reviewed patients who underwent two-stage SNM for FI at our institution between 2011-2021. Preoperative baseline characteristics and follow-up were obtained from the medical record and/or by telephone interview. Management and outcome of each postoperative event were evaluated by univariate and multivariate regression analyses. A total of 291 patients (85.2% female) were included in this study. Postoperative complications were recorded in 219 (75.2%) patients and 154 (52.9%) patients required surgical intervention to treat complications. The most common postoperative event was loss of efficacy (46.4%). Other common adverse events were problems at the implant site (pain, infection, etc.) in 16.5% and pain during stimulation in 11.7%. Previous vaginal delivery (OR 2.74, p = 0.003) and anal surgery (OR = 2.46, p = 0.039) were independent predictors for complications. Previous colorectal (OR = 2.04, p = 0.026) and anal (OR = 1.98, p = 0.022) surgery and history of irritable bowel syndrome (IBS) (OR = 3.49, p = 0.003) were independent predictors for loss of efficacy. Postoperative adverse events are frequently recorded after SNM. Loss of efficacy is the most common. Previous colorectal or anal surgery, vaginal delivery, and IBS are independent risk factors for complications.

Usefulness of the one-step technique in functional end-to-end anastomosis for colonic surgery: results of a prospective multicentre cohort study from the Japanese KYCC group.

Although functional end-to-end anastomosis (FEEA) using a stapler in the colorectal field has been recognised worldwide, the technique varies by surgeon, and the safety of anastomosis using different techniques is unknown. This multicentre prospective observational cohort study was conducted by the KYCC Study Group in Yokohama, Japan, and included patients who underwent colonic resection at seven centres between April 2020 and March 2022. This study compared the incidence of surgery-related abdominal complications (SAC: anastomotic leakage [AL], anastomotic bleeding, intra-abdominal abscess, enteritis, ileus, surgical site infection, and other abdominal complications) between two different methods of FEEA (one-step [OS] method: simultaneous anastomosis and bowel resection; two-step [TS] method: anastomosis after bowel resection). Complications of Clavien-Dindo classification grade2 or higher were assessed. Among 293 eligible cases, the OS and TS methods were used in 194 (66.2%) and 99 (33.8%) patients, respectively. The baseline characteristics were similar between the groups. The OS method used fewer staplers (three vs. four staplers, p < 0.00001). There were no significant differences in SAC rate between the OS (19.1%) and the TS (16.2%) groups (p = 0.44). The OS group had four cases (2.1%) of AL (two patients; grade3, two patients; grade2) while the TS group had one case (1.0%) of grade2 AL (p = 0.67). Multivariate logistic regression analysis showed that male sex (odds ratio [OR] 3.95; p < 0.00001), an open surgical approach (OR 2.36; p = 0.03), and longer operative duration (OR,2.79; p = 0.002) were independent predictors of complications, whereas the OS method was not an independent predictor (OR 1.17; p = 0.66). The OS and the TS technique for stapled colonic anastomosis in a FEEA had a similar postoperative complication rate. UMIN000039902 (registration date 23 March 2020).

Elevated Serum Alkaline Phosphatase is an Independent Predictor of Complications After Lumbar Spinal Fusion

BackgroundAlkaline phosphatase (ALP) is an enzyme which has been proven useful as a biomarker for bone turnover and inflammation. We hypothesized that high serum ALP levels are associated with increased complication rates following lumbar spinal fusion. MethodsLumbar spinal fusion procedures from 2005-2019 were queried from the national Surgical Quality Improvement Program (NSQIP) database. Serum alkaline phosphatase levels were stratified into low <44 IU/L, normal 44-147 IU/L, and high >147 IU/L. A risk-adjusted multivariate logistic regression was used to analyze ALP as an independent risk factor for complications. ResultsA total of 16,441 patients who underwent lumbar fusion procedures were included. Adjusted multivariate logistic regression analysis demonstrated that patients with a high serum ALP level had a significantly increased risk for developing septic shock (OR 4.68, 95% CI 1.83-11.97), pneumonia (OR 2.89, 95% CI 1.59-5.25), requiring a transfusion (OR 2.09, 95% CI 1.68-2.59), reoperation within 30 days (OR 1.68, 95% CI 1.12-2.52), readmission within 30 days (OR 1.60, 95% CI 1.16-2.21), increased length of stay (OR 1.87, 95% CI 1.49-2.36), and nonhome discharge (OR 2.18, 95% CI 1.80-2.66). Clinical RelevanceSerum alkaline phosphatase is a valuable and readily available tool for preoperative risk stratification of patients undergoing lumbar spinal fusion. ConclusionsElevated serum ALP in patients undergoing lumbar fusion procedures is associated with increased risk for multiple in-hospital complications as well as higher rates of readmission and reoperation.

Long-term outcomes after surgery for subaxial cervical spine injuries in octogenarians, a matched population-based cohort study

PurposeWe aimed to investigate surgical outcomes in octogenarians with subaxial cervical spine injuries and determine the predictors of complications and mortality.MethodsEligible for inclusion were all patients surgically treated between 2006 and 2018, with either anterior or posterior fixation for subaxial spine injuries. A cohort of octogenarians was identified and matched 1:1 to a corresponding cohort of younger adults. Primary outcomes were perioperative complications and mortality.ResultsFifty-four patients were included in each of the octogenarian and younger groups (median age: 84.0 vs. 38.5). While the risks for surgical complications, including dural tears and wound infections, were similar between groups, the risks of postoperative medical complications, including respiratory or urinary tract infections, were significantly higher among the elderly (p < 0.05). Additionally, there were no differences in operative time (p = 0.625) or estimated blood loss (p = 0.403) between groups. The 30 and 90-day mortality rates were significantly higher among the elderly (p = 0.004 and p < 0.001). These differences were due to comorbidities in the octogenarian cohort as they were revoked when propensity score matching was performed to account for the differences in American Society of Anesthesiology (ASA) grade. Multivariable logistic regression revealed age and ASA score to be independent predictors of complications and the 90-day mortality, respectively.ConclusionsOctogenarians with comorbidities were more susceptible to postoperative complications, explaining the increased short-term mortality in this group. However, octogenarians without comorbidities had similar outcomes compared to the younger patients, indicating that overall health, including comorbidities, rather than chronological age should be considered in surgical decision-making.

Trends in Elbow Ulnar Collateral Ligament Repairs and Reconstructions and an Analysis Between Low- and High-Volume Surgical Centers: A 10-Year Study in New York State.

Elbow ulnar collateral ligament (UCL) reconstruction (UCLR) is the gold standard for operative treatment of UCL tears, with renewed interest in UCL repairs. To (1) assess trends in rates of UCLR and UCL repair and (2) identify predictors of complications by demographic, socioeconomic, or surgical center volume factors. Descriptive epidemiology study. Patients who underwent UCLR or UCL repair at New York State health care facilities between 2010 and 2019 were retrospectively identified; concomitant ulnar nerve procedures among the cohort were also identified. Surgical center volumes were classified as low (<99th percentile) or high (≥99th percentile). Patient information, neighborhood socioeconomic status quantified using the Area Deprivation Index, and complications within 90 days were recorded. Poisson regression analysis was used to compare trends in UCLR versus UCL repair. Multivariable regression was used to determine whether center volume, demographic, or socioeconomic variables were independent predictors of complications. A total of 1448 UCL surgeries were performed, with 388 (26.8%) concomitant ulnar nerve procedures. UCLR (1084 procedures; 74.9%) was performed more commonly than UCL repair (364 procedures; 25.1%), with patients undergoing UCL repair more likely to be older, female, and not privately ensured and having undergone a concomitant ulnar nerve procedure (all P < .001). With each year, there was an increased incidence rate ratio for UCL repair versus UCLR (β = 1.12 [95% CI, 1.02-1.23]; P = .022). The authors identified 2 high-volume centers (720 UCL procedures; 49.7%) and 131 low-volume centers (728 UCL procedures; 50.3%). Patients undergoing UCL procedures at high-volume centers were more likely to be younger and male and receive workers' compensation (all P < .001). UCL repair and ulnar nerve-related procedures were both more commonly performed at low-volume centers (P < .001). There were no significant differences in 3-month infection, ulnar neuritis, instability, arthrofibrosis, heterotopic ossification, or all-cause complication rates between low- and high-volume centers. The only significant predictor for all-cause complication was Medicaid insurance (OR, 2.91 [95% CI, 1.20-6.33]; P = .011). A rising incidence of UCL repair compared with UCLR was found in New York State, especially among female patients, older patients, and nonprivate payers. There were no differences in 3-month complication rates between high- and low-volume centers, and Medicaid insurance status was a predictor for overall complications within 90 days of operation.

Elevated skull fractures: an institutional experience and individual participant data meta-analysis.

Elevated skull fracture (ESF) is a rare but potentially life-threatening type of skull fracture. The literature on this topic is relatively sparse. Herein, we conducted a meta-analysis of all the patients reported in the literature with ESFs with respect to their clinical management to better inform practice. On 20th of January 2023, we conducted a systematic search of literature to find all published cases of ESF. We also conducted a retrospective review of ESF cases from our institution. The data collection and analysis were conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. After screening, 28 studies met the inclusion criteria. A total of 104 individual patients were included in the meta-analysis, with a median age of 24 years and 85.7% of whom were males. 11 patients (11.2%) had an unfavorable outcome while 37 (35.2%) had one or more complications. We found that GCS on admission is an independent predictor of poor outcome in ESF (odds ratio (95% confidence interval) = 1.605 (1.110-2.315), p value = 0.012). Regarding complications, dural injury (odds ratio (95% confidence interval) = 66.667 (7.407-500.00), p value < 0.001) and multiple bone involvement (odds ratio (95% confidence interval) = 6.849 (2.127-22.222), p value = 0.001) were independent predictors of complication. ESFs represent a rare yet consequential form of cranial injury, carrying potentially life-threatening implications if not promptly addressed. In this study, we present the meta-analysis of outcomes and complications within this patient cohort, offering a comprehensive synthesis of existing literature on this pathology. However, further investigation is imperative to provide higher-quality evidence and address lingering uncertainties in the classification and management of ESFs.

When to ditch the ladder and take the elevator: The Anderson SArcoma Risk of Complications (A-SARC) score to guide reconstructive decision-making in extremity soft tissue sarcoma patients.

The reconstructive ladder relies mostly on defect size and depth to determine reconstructive technique, however, in actuality, many more variables ultimately inform reconstructive decision making, especially regarding extremity soft tissue sarcoma (eSTS) defects. The purpose of this study was to describe eSTS patients who will most optimally benefit from an advanced method of reconstruction (defined as a pedicled regional flap or free flap) and to create a simple risk assessment scale that can be employed in clinical practice. A single-institution retrospective cohort study examined patients undergoing resection of soft tissue sarcoma affecting the upper or lower extremities between 2016 and 2021. We categorized patients who required a pedicled or free flap as having had advanced reconstruction, and all other techniques were considered simple reconstruction. A regression was used to create a risk scale to guide reconstructive decision-making. The following variables were identified as independent predictors of complications and used to create our risk scale: lower extremity tumor location, preoperative radiotherapy, tumor bed excision, male sex, hypertension, and tumor volume. Intermediate and high-risk patients reconstructed using simple techniques had significantly greater overall complication rates compared to those reconstructed with advanced techniques. Major complications were significantly greater in low-risk patients reconstructed with advanced techniques. To minimize postoperative wound complications, low-risk patients should receive simple methods of reconstruction, whereas high-risk patients should be reconstructed using advanced techniques.

5-Factor Modified Frailty Index as a Predictor of Outcomes After Hemiarthroplasty or Total Hip Arthroplasty for Femoral Neck Fracture.

Although the 5-factor modified frailty index (mFI-5) has been shown to be an independent predictor of complications after primary total hip arthroplasty (THA), its predictive value has not been evaluated in the setting of hip fracture. We therefore assessed the utility of mFI-5 score as an independent predictor of morbidity and mortality in patients who underwent THA or hemiarthroplasty for femoral neck fracture. The American College of Surgeons National Surgical Quality Improvement database was queried for all patients with femoral neck fractures treated with THA or hemiarthroplasty between 2006 and 2020. A multivariate logistic regression analysis was done using mFI-5 as a predictor while controlling for baseline demographic and clinical variables. In total, 45,185 patients (hemiarthroplasty: 37,645; THA: 7,540) were identified. For hemiarthroplasty patients, the mFI-5 strongly predicted risk of any complication (OR, 1.1; 95% CI, 1.1 to 1.2; P < 0.001), bleeding (OR, 1.2; 95% CI, 1.1 to 1.3; P < 0.001), and readmission (OR, 1.2; 95% CI, 1.1 to 1.3; P < 0.001). For THA patients, the mFI-5 was a strong predictor of any complication (OR, 1.2; 95% CI, 1.0 to 1.3; P = 0.023), pneumonia (OR, 1.4; 95% CI, 1.0 to 2.0; P = 0.047), and readmission (OR, 1.3; 95% CI, 1.1 to 1.6; P = 0.004). The mFI-5 is an independent predictor of morbidity and complications after hemiarthroplasty and THA for femoral neck fracture. Importantly, readmission risk was predicted by the mFI-5. The mFI-5 may present a valuable clinical tool for assessment of high-risk patients who might require additional resources and specialized care after femoral neck fracture.

Race and Ethnicity Independently Predict Adverse Outcomes Following Head and Neck Autograft Surgery.

There is growing attention toward the implications of race and ethnicity on health disparities within otolaryngology. While race is an established predictor of adverse head and neck oncologic outcomes, there is paucity in the literature on studies employing national, multi-institutional data to assess the impact of race and ethnicity on head and neck autograft surgery. Using the National Surgical Quality Improvement Program (NSQIP) database, trends in 30 days outcomes were assessed. Patients with ICD-10 codes for malignant head and neck neoplasms were isolated. Autograft surgeries were selected using Current Procedural Terminology (CPT) codes for free flap and pedicled flap reconstruction. Primary outcomes included surgical complications, reoperation, readmission, extended length of stay and operation time. Each binary categorical variable was compared to racial/ethnic identity via binary logistic regression. The study cohort consisted of 2447 patients who underwent head and neck autograft surgery (80.71% free flap reconstruction and 19.39% pedicled flap reconstruction). Black patients had significantly higher odds of overall surgical complications (odds ratio [OR] 1.583, 95% confidence interval [CI] 1.091, 2.298, p = 0.016) with much higher odds of perioperative blood transfusions (OR 2.291, 95% CI 1.532, 3.426, p = <.001). Hispanic patients were more likely to undergo reoperation within 30 days after surgery and were more likely to be hospitalized for more than 30 days post-operatively (OR 1.566, 95% CI 1.015, 2.418, p = 0.043 and OR 12.224, 95% CI 2.698, 55.377, p = 0.001, respectively). Race and ethnicity serve as independent predictors of complications in the post-operative period following head and neck autograft surgery. 3 Laryngoscope, 134:3595-3603, 2024.

Predictive factors of surgical complications after pelvic exenteration for gynecological malignancies: a large single-institution experience.

To evaluate pre-operative predictors of early (<30 days) severe complications (grade Dindo 3+) in patients with gynecological malignancy submitted to pelvic exenteration (PE). We retrospectively analyzed 129 patients submitted to surgery at Fondazione Policlinico Gemelli between 2010 and 2019. We included patients affected by primary or recurrent/persistent cervical, endometrial, or vulvar/vaginal cancers. Post-operative complications were graded according to the Dindo classification. Logistic regression was used to analyze potential predictors of complications. We performed 63 anterior PE, 10 posterior PE, and 56 total PE. The incidence of early severe post-operative complications was 27.9% (n=36), and the early mortality rate was 2.3% (n=3). More frequent complications were related to the urinary diversion and intestinal surgery. In univariable analysis, hemoglobin ≤10 g/dL (odds ratio [OR]=4.2; 95% confidence interval [CI]=1.65-10.7; p=0.003), low albumin levels (OR=3.9; 95% CI=1.27-12.11; p=0.025), diabetes (OR=4.15; 95% CI=1.22-14.1; p=0.022), 2+ comorbidities at presentation (OR=5.18; 95% CI=1.49-17.93; p=0.012) were predictors of early severe complications. In multivariable analysis, only low hemoglobin and comorbidities at presentation were independent predictors of complications. Pelvic exenteration is an aggressive surgery characterized by a high rate of post-operative complications. Pre-operative assessment of comorbidities and patient health status are crucial to better select the right candidate for this type of surgery.

Stapler size independently predicts postoperative complications following stapled ileocolic anastomosis: Aretrospective cohort study.

Staplers used in ileocolic anastomosis construction differ in length and height. We assessed the impact of stapler type in creating ileocolic anastomoses on postoperative outcomes. This retrospective cohort study of an Institutional Review Board approved database included patients who underwent laparoscopic right colectomy for cancer between January 2011 and August 2021. All patients had construction of extracorporeal antiperistaltic stapled ileocolic anastomosis using a linear cutting stapler. Main outcome measures were short-term (<30 day) morbidity and mortality. In all, 270 patients (136 men; median age 70.2 years) were included. A 75 mm stapler was used in 49 (18.1%) patients, 80 mm in 97 (35.9%) and 100 mm in 124 (45.9%). Blue cartridge (stapler height 3.5 mm) was used in 175 (64.5%) and green cartridge (4.8 mm) in 18 (7%) patients; this information was unavailable in 77 (28.5%) cases. Apical enterotomy closure was performed by linear stapler in 54% and linear cutting stapler in 46%. Apical staple line reinforcement or imbrication suturing was used in 26.3%. The overall postoperative complication rate was 28.9%. The anastomotic leak rate was 2.6%. Independent predictors of complications after laparoscopic right colectomy were older age (OR 1.03, 95%CI 1-1.06; P = 0.01), extended colectomy (OR 2.76, 95%CI 1.07-7.08; P = 0.035) and emergency surgery (OR 4.5, 95%CI 1.3-14.9; P = 0.014). A 100-mm linear cutting stapler was an independent protective factor against postoperative complications (OR 0.3, 95%CI 0.18-0.85; P = 0.019). Stapler height and closure technique of apical enterotomy did not affect postoperative complications. Independent predictors of complications after laparoscopic right colectomy were older age, extended colectomy and emergency surgery. Using a 100 mm stapler was an independent protective factor against postoperative complications.

The Role of Insulin Resistance in the Development of Complications after Coronary Artery Bypass Grafting in Patients with Coronary Artery Disease.

Patients with coronary artery disease who underwent CABG (n = 383) were examined to determine glycemic status, free fatty acid and fasting insulin levels, and insulin resistance indices (Homeostasis Model Assessment of Insulin Resistance (HOMA-IR), McAuley index, Quantitative Insulin Sensitivity Check Index (QUICKI), Revised-QUICKI). Patients were assessed for the development of perioperative complications and their length of stay in the hospital. Two groups were formed: group 1, patients with a combined endpoint (CEP, any complication and/or duration of hospital stay >10 days), n = 291; and group 2 (n = 92) without a CEP. Perioperative characteristics were analyzed, and predictors of hospital complications and prolonged hospital stay were evaluated. Patients in the CEP group were older, and there were more women among them (p = 0.003). Additionally, in this group, there were more patients with diabetes mellitus (37.5% vs 17.4%, p < 0.001), obesity (p < 0.001), and a higher percentage of combined operations (p = 0.007). In the group with a CEP, the levels of glucose (p = 0.031), glycated hemoglobin (p = 0.009), and free fatty acids (p = 0.007) and the Revised-QUICKI (p = 0.020) were higher than in the group without complications. In a regression analysis, the independent predictors of complications were combined operations (p = 0.016) and the predictors of a long hospital stay (>14 days) were female gender, the left atrium size, and diabetes mellitus (p < 0.001). The predictors of a composite endpoint included female gender, age, the left atrium size, and free fatty acid levels (p < 0.001). In the group with in-hospital complications after CABG, not only was the presence of diabetes mellitus more often detected, but there were also higher levels of free fatty acids and a higher Revised-QUICKI. Therefore, additional assessments of insulin resistance and free fatty acid levels are advisable in patients before CABG.

Long-term Outcomes of Laparoscopic Sleeve Gastrectomy as a Revisional Procedure Following Adjustable Gastric Banding: Variations in Outcomes Based on Indication

BackgroundSignificant controversy exists regarding the indications and outcomes after laparoscopic adjustable gastric banding (LAGB) conversions to laparoscopic sleeve gastrectomy (LSG).AimTo comprehensively determine the long-term outcomes of sleeve gastrectomy as a revisional procedure after LAGB across a range of measures and determine predictors of outcomes.MethodsSix hundred revision LSG (RLSG) and 1200 controls (primary LSG (PLSG)) were included. Patient demographics, complications, follow-up, and patient-completed questionnaires were collected.ResultsRLSG vs controls; females 87% vs 78.8%, age 45 ± 19.4 vs 40.6 ± 10.6 years, p = 0.561; baseline weight 119.7 ± 26.2 vs 120.6 ± 26.5 kg p = 0.961). Follow-up was 87% vs 89.3%. Weight loss in RLSG at 5 years, 22.9% vs 29.6% TBWL, p = 0.001, 10 years: 19.5% vs 27% TBWL, p = 0.001. RLSG had more complications (4.8 vs 2.0% RR 2.4, p = 0.001), re-admissions (4.3 vs 2.4% RR 1.8, p = 0.012), staple line leaks (2.5 vs 0.9%, p = 0.003). Eroded bands and baseline weight were independent predictors of complications after RLSG. Long-term re-operation rate was 7.3% for RLSG compared to 3.2% in controls. Severe oesophageal dysmotility predicted poor weight loss. RLSG reported lower quality of life scores (SF-12 physical component scores 75.9 vs 88%, p = 0.001), satisfaction (69 vs 93%, p = 0.001) and more frequent regurgitation (58% vs 42%, p = 0.034).ConclusionRLSG provides long-term weight loss, although peri-operative complications are significantly elevated compared to PLSG. Longer-term re-operation rates are elevated compared to PLSG. Four variables predicted worse outcomes: eroded band, multiple prior bands, severe oesophageal dysmotility and elevated baseline weight.Graphical

Revisional Procedures after Sleeve Gastrectomy for Weight Recurrence or Inadequate Weight Loss: An Analysis of the MBSAQIP Database.

The safety of conversional bariatric procedures after sleeve gastrectomy (SG) for weight recurrence (WR) or inadequate weight loss (IWL) is debated due to limited evidence. Conversion options include Roux-en-Y gastric bypass (RYGB), single anastomosis duodeno-ileal bypass (SADI), and biliopancreatic diversion with duodenal switch (BPD-DS). We aimed to compare serious complications and mortality rates between these procedures within 30 days. Using the 2020 and 2021 MBSAQIP databases, we identified patients who underwent a conversion from SG to RYGB, SADI, or BPD-DS. We performed a multivariable logistic regression to assess predictors of 30-day complications and mortality. Among 7388 patients (77.6% RYGB, 8.7% SADI, 13.7% BPD-DS), those undergoing SADI and BPD-DS had higher preoperative body mass index. Conversion reasons included WR (63.0%) and IWL (37.0%). SADI and BPD-DS patients had longer operative times (p < 0.001) and higher leak rates (p = 0.001). Serious complications, reoperations, readmissions, and 30-day mortality were similar across groups. Conversion procedure type was not an independent predictor of complications. RYGB was the most performed conversional procedure after SG. The study indicated a similar safety profile for revisional RYGB, SADI, and BPD-DS, with comparable 30-day complications and mortality rates. However, SADI and BPD-DS patients had longer operative time and higher leak rates.

ANEMIA AND LONG-TERM SURVIVAL OF PATIENTS AFTER MITRAL VALVE SURGERY

HighlightsThe authors have studied anemia`s impact on the long-term mortality after mitral valve surgery. The research results indicate the need to address this modifiable factor in the preoperative period. Aim. To analyze the impact of anemia on the long-term survival of patients after mitral valve surgery.Methods. The study included 103 patients, 46 of them were men, 57 were women. Thirteen patients presented with anemia before surgery, and 90 patients did not have anemia. The survival rate of patients was compared using the Kaplan-Meier estimate.Results. The survival rate after surgery in the group of patients without anemia was higher compared with patients with anemia (p = 0,002). By the end of the follow-up period, the survival rate among patients without anemia reached 50.2%, whereas among patients with anemia it was 0.0%.Conclusion. Anemia is an independent predictor of complications in the postoperative period in patients with low preoperative hemoglobin levels. According to the results, the presence of anemia increases the risk of adverse events by 7.71 times in the preoperative period. Moreover, patients without anemia had the highest (up to 50.2%) survival rate in the long-term period, while patients with anemia had a survival rate equal to 0.0%.

Does the type of anesthesia (regional vs. general) represent an independent predictor for in-hospital complications in operatively treated malleolar fractures? A retrospective analysis of 5262 patients

PurposeThe impact of the type of anesthesia (regional vs. general anesthesia) on in-hospital complications in ankle fractures has not been thoroughly studied yet. Identifying factors that place patients at risk for complications following ankle fractures may help reduce their occurrence. The primary goal of this study was (1) to describe the cohort of patients and (2) to evaluate independent risk factors for complications during hospitalization.MethodsWe analyzed patients from 2005 to 2019 with an operatively treated isolated fracture of the medial or lateral malleolus using a prospective national quality measurement database. Patients were selected based on international classifications (ICD) and national procedural codes (CHOP). Uni- and multivariate analysis were applied.ResultsIn total, we analyzed 5262 patients who suffered a fracture of the malleolus; 3003 patients (57%) had regional and 2259 (43%) general anesthesia. Patients with regional anesthesia were significantly older (51 vs. 46 years), but healthier (23 vs. 28% comorbidities) than patients who received general anesthesia. The in-hospital complication rate was not significantly lower in regional anesthesia (2.2% vs 3.0%). The type of anesthesia was not an independent predictor for complications while controlling for confounders.ConclusionType of anesthesia was not an independent predictor of complications; however, higher ASA class, age over 70 years, fracture of the medial versus lateral malleolus, longer preoperative stay, and duration of surgery were significant predictors of complications. Patient and procedure characteristics, as well as changes in medical care and epidemiological changes along with patient requests, influenced the choice of the type of anesthesia.

Impact of Systematic Use of Intracardiac Ultrasound during Transseptal Catheterization in the Electrophysiology Laboratory

To explore the impact of the use of intracardiac echocardiography (ICE) in the ablation of supraventricular arrhythmias requiring transseptal catheterization (TSC), whilst analyzing the reduction in periprocedural complications and complications specifically related to TSC. A retrospective multicenter study collecting data from consecutive atrial fibrillation (AF) and supraventricular ablation procedures that required TSC was performed in five Italian centers. Based on physician discretion, TSC was performed with or without ICE. Periprocedural complications, separating all complications from complications directly related to TSC, were collected. Independent predictors of periprocedural complications and TSC-related complications were investigated. A total of 2181 TSCs were performed on 1862 patients at five Italian centers from 2006 to 2021, in 76% of cases by AF ablation and in 24% by ablation of other arrhythmias with a circuit in the left atrium. Overall, 1134 (52%) procedures were performed with ICE support and 1047 (48%) without ICE. A total of 67 (3.1%) complications were detected, 19 (1.7%) in the ICE group and 48 (4.6%) in the no ICE group, p < 0.001. A total of 42 (1.5%) complications directly related to TSC: 0.9% in the ICE group and 3.1% in the no ICE group (p < 0.001). The independent predictors of all complications were age (OR 1,02 95% C.I 1.00-1.05; p = 0.036), TSC with the use of ICE (OR 0.27 95% C.I 0.15-0.46; p < 0.001) and AF ablation (OR 2,25 95%C.I 1.05-4.83; p = 0.037). The independent predictors for TSC complications were age (OR 1.03 95% C.I 1.01-1.06; p = 0.013) and TSC with the use of ICE (OR 0.24 95% C.I 0.11-0.49; p < 0.001). ICE reduced periprocedural and TSC-related complications during electrophysiological procedures for ablation of left atrial arrhythmias.
