PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2024; 12:e5741. [PMID: 38645631 PMCID: PMC11030000 DOI: 10.1097/gox.0000000000005741] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2023] [Accepted: 02/20/2024] [Indexed: 04/23/2024]
Abstract
Background Venous thromboembolism (VTE) is a dangerous postoperative complication after abdominal wall reconstruction (AWR). Intraoperative core body temperature has been associated with thrombotic events in other surgical contexts. This study examines the effects of intraoperative temperature on VTE rate after AWR. Methods A retrospective study was performed on AWR patients. Cohorts were defined by postoperative 30-day VTE. Intraoperative core body temperature was recorded as the minimum, maximum, and mean intraoperative temperatures. Study variables were analyzed with logistic regression and cutoff analysis to assess for association with VTE. Results In total, 344 patients met inclusion criteria. Fourteen patients were diagnosed with 30-day VTE for an incidence of 4.1%. The VTE cohort had a longer median inpatient stay (8 days versus 5 days, P < 0.001) and greater intraoperative change in peak inspiratory pressure (3 mm H2O versus 1 mm H2O, P = 0.01) than the non-VTE cohort. Operative duration [odds ratio (OR) = 1.32, P = 0.01], length of stay (OR = 1.07, P = 0.001), and intraoperative PIP difference (OR = 1.18, P = 0.045) were significantly associated with 30-day VTE on univariable regression. Immunocompromised status (OR = 4.1, P = 0.023; OR = 4.0, P = 0.025) and length of stay (OR = 1.1, P < 0.001; OR = 1.1, P < 0.001) were significant predictors of 30-day VTE on two multivariable regression models. No significant associations were found between temperature metrics and 30-day VTE on cutoff point or regression analysis. Conclusions Intraoperative core body temperature did not associate with 30-day VTE after AWR, though operative duration, length of stay, immunocompromised status, and intraoperative PIP difference did. Surgeons should remain mindful of VTE risk after AWR, and future research is warranted to elucidate all contributing factors.

Risk factors of venous thromboembolism after incisional ventral hernia repair. Hernia 2022:10.1007/s10029-022-02726-3. [PMID: 36471032 DOI: 10.1007/s10029-022-02726-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2022] [Accepted: 11/20/2022] [Indexed: 12/12/2022]
Abstract
BACKGROUND The problem of venous thromboembolic events (VTE) after incisional hernia repair remains relevant. According to the literature the frequency of VTE ranges from 0.2 to 4.2%. The data on risk factors of VTE in this cohort of patients are scarce. Aim of our study is to find frequency and risk factors for VTE development in patients who underwent surgery for incisional ventral hernia. MATERIALS AND METHODS There were 240 patients enrolled in our retrospective study. We included patients, who were operated for incisional hernia in Saveljev University Surgery Clinic from January 2018 to December 2019. Compression duplex ultrasound of lower extremity veins was performed within median 3 days (min 1 day, max 7 days) after surgery for all participants. The primary endpoint was the occurrence of the VTE event, including deep venous thrombosis (DVT) and pulmonary embolism (PE). RESULTS VTE was detected in 19 patients, which accounted for 7.9% in analyzed cohort. All patients received standard pharmacological prophylaxis. There were 3 (1.3%) proximal, 16 (6.7%) distal DVT, in one patient (0.4%) distal thrombosis was complicated by symptomatic pulmonary embolism. In multivariate Cox proportional hazard model was found that component separation (HR 3.99, 95% CI 1.14-14.0, p = 0.03), duration of operation in hours (HR 1.67. 95% CI 1.13-2.5, p = 0.011) and body mass index (HR 1.13, 95% CI 1.02-1.2, p = 0.02) were statistically significant risk factors. CONCLUSION The incidence of postoperative VTE in patients after incisional hernia repair is high with a predominant distal DVT as a thrombotic event. Component separation, duration of operation and body mass index are statistically significant factors of VTE in patients undergoing surgery for incisional hernia.

Abstract
BACKGROUND Venous thromboembolism (VTE) is a major source of morbidity and mortality after ventral hernia surgery, but the risk of VTE after discharge has not been reported. STUDY DESIGN Data from the American College of Surgeons-National Surgical Quality Improvement Program (ACS-NSQIP) were used to investigate the risk of post-discharge VTE. Current procedural terminology (CPT) codes identified all reported patients who underwent ventral hernia repair from 2011 to 2017. We created a multivariable regression model for post-discharge VTE, using the 2011-2016 dataset to develop the model and 2017 as a validation set. The prediction model was used to create a risk calculator as a mobile application. RESULTS The rate of VTE after surgery was 0.62% (878 of 141,065) with 48% occurring after discharge from the hospital. The final predictor model consisted of eight variables: age > 60 years, male sex, body mass index (BMI) ≥ 35 kg/m2), operative time > 2 h, concurrent panniculectomy, post-operative hospitalization > 1 day, presence of bleeding disorder, and emergency operation. The model had good calibration and discrimination (Hosmer-Lemeshow goodness-of-fit test, p = 0.71; c-statistic = 0.71). Threshold analysis showed a strategy of extended-duration thromboprophylaxis was optimized when the risk of post-discharge VTE was > 0.3%. CONCLUSION Forty-eight percent of VTEs after ventral hernia repair occur after discharge, particularly in older, male, obese patients undergoing longer and complex operations that require hospitalization > 1 day. Post-discharge thromboprophylaxis should be considered in these patients, particularly when risk of VTE exceeds 0.3%.

Abstract
BACKGROUND Blood transfusions can affect the clotting cascade, leading to a hypercoagulable state. The association of a venous thromboembolic (VTE) event and perioperative blood transfusion has been identified previously in surgical patients, but not after ventral hernia repair (VHR). The aim of this study was to evaluate the risk of VTE in VHR patients who receive a perioperative blood transfusion. METHODS The American College of Surgeons National Surgery Quality Improvement Program was queried for open (n = 34,687) and laparoscopic (n = 11,544) VHRs that occurred from 2013 to 2015. Regression analyses were used to determine factors predictive of VTE within 30-day post-operatively, the impact of bleeding requiring blood transfusion, and the influence of surgical approach on VTE. RESULTS Post-operative VTE occurred in 246 (0.5%) VHR patients. Among those patients, 53.0% occurred after discharge. Increased age, operative time, and comorbidities increased the risk of VTE (p < 0.05). Controlling for surgical approach, perioperative blood transfusion increased the risk of VTE 10.2-fold (p < 0.0001) in open and 12.2-fold in laparoscopic VHR (p < 0.0001). CONCLUSION Perioperative blood transfusions are associated with an increased rate of VTE following VHR, more than 50% of which occur after discharge. This study highlights the importance of identifying quality initiatives for at risk patients, including adequate VTE screening and potential prophylaxis for those who receive perioperative blood transfusions.

Abstract
Background The National Surgical Quality Improvement Program (NSQIP) is a robust, high-quality surgical outcomes database that measures risk-adjusted 30-day outcomes of surgical interventions. The purpose of this scoping review is to describe how the NSQIP is being used in plastic surgery research. Methods A comprehensive electronic literature search was completed in PubMed, Embase, MEDLINE, and CINAHL. Two reviewers independently reviewed articles to determine their relevance using predefined inclusion criteria. Articles were included if they utilized NSQIP data to conduct research in a domain of plastic surgery or analyzed surgical procedures completed by plastic surgeons. Extracted information included the domain of plastic surgery, country of origin, journal, and year of publication. Results A total of 106 articles met the inclusion criteria. The most common domain of plastic surgery was breast reconstruction representing 35% of the articles. Of the 106 articles, 95% were published within the last 5 years. The Plastic and Reconstructive Surgery journal published most of the (59%) NSQIP-related articles. All of the studies were retrospective. Of note, there were no articles on burns and only one study on trauma as the domain of plastic surgery. Conclusion This scoping review describes how NSQIP data are being used to analyze plastic surgery interventions and outcomes in order to guide quality improvement in 106 articles. It demonstrates the utility of NSQIP in the literature, however also identifies some limitations of the program as it applies to plastic surgery.

Abstract
Supplemental Digital Content is available in the text. Background: The aim was to assess reliability of the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) 30-day perioperative outcomes and complications for immediate, free-tissue transfer breast reconstruction by direct comparisons with our 30-day and overall institutional data, and assessing those that occur after 30 days. Methods: Data were retrieved for consecutive immediate, free-tissue transfer breast reconstruction patients from a single-institution database (2010–2015) and the ACS-NSQIP (2011–2014). Multiple logistic regressions were performed to compare adjusted outcomes between the 2 datasets. Results: For institutional versus ACS-NSQIP outcomes, there were no significant differences in surgical-site infection (SSI; 30-day, 3.6% versus 4.1%, P = 0.818; overall, 5.3% versus 4.1%, P = 0.198), wound disruption (WD; 30-day, 1.3% versus 1.5%, P = 0.526; overall, 2.3% versus 1.5%, P = 0.560), or unplanned readmission (URA; 30-day, 2.3% versus 3.3%, P = 0.714; overall, 4.6% versus 3.3%, P = 0.061). However, the ACS-NSQIP reported a significantly higher unplanned reoperation (URO) rate (30-day, 3.6% versus 9.5%, P < 0.001; overall, 5.3% versus 9.5%, P = 0.025). Institutional complications consisted of 5.3% SSI, 2.3% WD, 5.3% URO, and 4.6% URA, of which 25.0% SSI, 28.6% WD, 12.5% URO, and 7.1% URA occurred at 30–60 days, and 6.3% SSI, 14.3% WD, 18.8% URO, and 42.9% URA occurred after 60 days. Conclusion: For immediate, free-tissue breast reconstruction, the ACS-NSQIP may be reliable for monitoring and comparing SSI, WD, URO, and URA rates. However, clinicians may find it useful to understand limitations of the ACS-NSQIP for complications and risk factors, as it may underreport complications occurring beyond 30 days.

Abstract
BACKGROUND Ventral hernia repair is a common procedure and is undertaken by surgeons with varying training backgrounds. Outcomes after hernia repair depend on numerous factors, some being patient or surgeon specific. It remains unclear what the ideal roles are for general and plastic surgeons in open ventral hernia repair. We hypothesized that open ventral hernia repair by plastic surgeons is safe and comparable with general surgeons. METHODS We performed a retrospective observational study using data from the National Surgical Quality Improvement Program database from 2007 to 2013. Patients with a primary diagnosis of ventral hernia undergoing open repair were identified. Multivariate regression modeling was performed, adjusting for surgeon specialty, patient characteristics, common concurrent procedures, and the total number of concurrent procedures. Outcomes studied were major and minor 30-day complications, operation time, readmission, unplanned reoperation, and length of hospital stay. RESULTS We identified 53,746 patients who underwent open repair, 53,282 (99.1%) by general surgeons (GS) and 464 (0.9%) by plastic surgeons (PS). There were significantly different rates of concurrent panniculectomy (12.1% PS vs 2.4% GS) and component separation (24.8% PS vs 5.3% GS), representing increased PS case complexity. 52.3% of GS and 92.9% of PS performed panniculectomy without an alternate specialty surgeon. 81.3% of GS and 97.4% of PS performed component separation without an alternate specialty surgeon. The PS patients had a significantly longer uncorrected length of stay and operation time than GS patients (all P < 0.001). Similarly, PS was positively associated with uncorrected major and minor complications (P < 0.001). However, these relationships did not persist on multivariate analysis after adjusting for demographic characteristics, medical comorbidities, concurrent procedures, and total procedure load. Furthermore, PS was associated with lower odds of major complications (operating room, 0.49; P = 0.05) compared with GS. CONCLUSIONS Outcomes of hernia repair by plastic surgeons are comparable with general surgeons, despite plastic surgeons being involved in many complex cases. Interestingly, we identified that general surgeons are performing adjunctive procedures to ventral hernia previously handled by plastic surgeons. Although further study is warranted, we conclude that for open ventral hernia repair, plastic surgeons provide a comparable alternative to general surgeons.
