imageObjective: The aim of this study was to identify examples of naturalistic coaching behavior among practicing surgeons operating together by analyzing their intraoperative discussion. Background: Opportunities to improve surgical performance are limited for practicing surgeons; surgical coaching is one strategy to address this need. To develop peer coaching programs that integrate with surgical culture, a better understanding is needed of how surgeons routinely discuss operative performance. Methods: As part of a "co-surgery" quality improvement program, 20 faculty surgeons were randomized into 10 dyads who performed an operation together. Discourse analysis was conducted on transcribed intraoperative discussions. Themes were coded using an existing framework of surgical coaching principles (self-identified goals, collaborative analysis, constructive feedback, peer learning support) and surgical coaching content (technical skills, nontechnical skills). Coaching principles were cross-referenced with coaching content; c-coefficient measured the strength of association between pairs of themes. Results: Overall, 44 unique coaching examples were identified in 10 operations. Of the 4 principles of surgical coaching, only self-identified goals and collaborative analysis were identified consistently. Self-identified goals were most associated with discussions regarding technical skills of "tissue exposure," "flow of operation," and "instrument handling" and the nontechnical skill "situation awareness." Collaborative analysis was most associated with discussions regarding technical skills of "respect for tissue" and "flow of operation" and nontechnical skills of "communication and teamwork." Conclusions: In naturalistic discussions between practicing surgeons in the operating room, numerous examples of unprompted coaching behavior were identified that target intraoperative performance. Prominent coaching gaps—constructive feedback and peer learning support—were also observed. Surgical coach trainings should address these gaps.

A Single Preoperative Dose of Tranexamic Acid Reduces Perioperative Blood Loss: A Meta-analysis

xloma.fota13 shared this article with you from Inoreader
imageObjective: To review the efficacy and safety of a single dose of intravenous tranexamic acid (TXA) given preoperatively. Summary Background Data: TXA is a synthetic antifibrinolytic that has been used in various surgical disciplines to reduce blood loss, blood transfusions, ecchymosis, and hematoma formation. However, there is no universal standard on the most effective dose and route of TXA administration, limiting its routine use in many centers. This study evaluates the current evidence for the efficacy and safety of a single preoperative dose of TXA on surgical blood loss in all surgical disciplines. Methods: With the guidance of a research librarian, in accordance with the Cochrane Handbook Medline, Cochrane Central and Embase were searched in November 2018. Search terms included "Tranexamic Acid" AND "Intravenous," with studies limited to randomized controlled trails in adult humans. Two independent reviewers and an arbitrator assessed articles for inclusion. Criteria included a single preoperative bolus dose of intravenous TXA, surgical patients, and intraoperative blood loss measurement or perioperative blood loss up to 24 hours postsurgery. Quality assessment was done using the Cochrane Collaboration risk-of-bias tool by 2 reviewers. Statistical analysis was carried out using Cochrane Review Manager 5.3. The primary outcome was surgical blood loss. Secondary outcomes included venous thromboembolic complications, transfusion requirements, and dosing. Results: A total of 1906 articles were screened, 57 met inclusion criteria. The majority of included studies were orthopedic (27), followed by obstetric and gynecological (16), oral maxillofacial and otolaryngology (10), cardiac (3), and 1 plastic surgery study focusing on acute burn reconstruction. Across all surgical specialties (n = 5698), the perioperative estimated blood loss was lower in patients receiving TXA, with a standard mean difference of −153.33 mL (95% CI = −187.79 to −118.87). Overall, surgical patients with TXA had a 72% reduced odds of transfusion (odds ratio = 0.28 [95% CI = 0.22–0.36]). The most frequently used dose of TXA was 15 mg/kg. There was no difference in the incidence of venous thromboembolic events between TXA and control groups. Conclusions: While there is a growing body of evidence to support benefits of perioperative TXA use, this is the first meta-analysis to identify the efficacy and safety of a single preoperative dose of IV TXA. The potential implications for expanding the use of preoperative TXA for elective day surgery procedures is substantial. Preoperative intravenous TXA reduced perioperative blood loss and transfusion requirements in a variety of surgical disciplines without increasing the risk of thromboembolic events. Therefore, it should be considered for prophylactic use in surgery to reduce operative bleeding.

Prolonged Air Leak After Pulmonary Resection Increases Risk of Noncardiac Complications, Readmission, and Delayed Hospital Discharge: A Propensity Score-adjusted Analysis

xloma.fota13 shared this article with you from Inoreader
imageObjective: The aim of the study was to determine whether prolonged air leak (PAL) is associated with postoperative morbidity and mortality following pulmonary resection after adjusting for differences in baseline characteristics using propensity score analysis. Summary Background Data: Patients with PAL after lung resection have worse outcomes than those without PAL. However, adverse postoperative outcomes may also be secondary to baseline risk factors, such as poor lung function. Methods: Patients who underwent pulmonary resection for lung cancer/nodules (1/2009–6/2014) were stratified by the presence of PAL [n = 183 with/1950 without; defined as >5 d postoperative air leak; n = 189 (8.3%)]; probability estimates for propensity for PAL from 31 pretreatment/intraoperative variables were generated. Inverse probability-of-treatment weights were applied and outcomes assessed with logistic regression. Results: Standardized bias between groups was significantly reduced after propensity weighting (mean = 0.18 before vs 0.08 after, P

Laparoscopic Sleeve Gastrectomy Versus Laparoscopic Roux-en-Y Gastric Bypass: A Systematic Review and Meta-analysis of Weight Loss, Comorbidities, and Biochemical Outcomes From Randomized Controlled Trials

xloma.fota13 shared this article with you from Inoreader
imageObjective: The aim of this study was to compare weight loss, obesity-related comorbidities, and biochemical outcomes of LSG versus LRYGB through a meta-analysis of randomized controlled trials (RCTs). Summary of Background Data: LSG and LRYGB are the 2 most commonly performed bariatric surgeries for the treatment of obesity. The comparative outcomes of the 2 surgeries is a topic of ongoing debate and medium-term outcomes remain uncertain. Methods: A search for RCTs comparing LRYGB versus LSG was conducted. Pooled outcomes between 2 procedures were compared using pairwise random-effects meta-analysis at 1, 3, and 5-year follow-up time points. Grading of recommendations, assessment, development, and evaluation was used to assess certainty of evidence. Results: Thirty-three studies involving 2475 patients were included. LRYGB resulted in greater loss of body mass index compared to LSG at 1 year [mean difference −1.25 kg/m2, 95% confidence interval (CI) −2.01 to −0.49, P = 0.001; moderate certainty of evidence] which persisted at 3 years, but there was insufficient evidence at 5 years. Resolution of dyslipidemia was higher for LRYGB than LSG at 1 year (risk ratio 0.58, 95% CI 0.46–0.73, P

Practice Patterns and Perioperative Outcomes of Laparoscopic Pancreaticoduodenectomy in China: A Retrospective Multicenter Analysis of 1029 Patients

xloma.fota13 shared this article with you from Inoreader
imageObjective: The aim of the study was to analyze the outcomes of patients who have undergone laparoscopic pancreaticoduodenectomy (LPD) in China. Summary Background Data: LPD is being increasingly used worldwide, but an extensive, detailed, systematic, multicenter analysis of the procedure has not been performed. Methods: We retrospectively reviewed 1029 consecutive patients who had undergone LPD between January 2010 and August 2016 in China. Univariate and multivariate analyses of patient demographics, changes in outcome over time, technical learning curves, and the relationship between hospital or surgeon volume and patient outcomes were performed. Results: Among the 1029 patients, 61 (5.93%) required conversion to laparotomy. The median operation time (OT) was 441.34 minutes, and the major complications occurred in 511 patients (49.66%). There were 21 deaths (2.43%) within 30 days, and a total of 61 (5.93%) within 90 days. Discounting the effects of the early learning phase, critical parameters improved significantly with surgeons' experience with the procedure. Univariate and multivariate analyses revealed that the pancreatic anastomosis technique, preoperative biliary drainage method, and total bilirubin were linked to several outcome measures, including OT, estimated intraoperative blood loss, and mortality. Multicenter analyses of the learning curve revealed 3 phases, with proficiency thresholds at 40 and 104 cases. Higher hospital, department, and surgeon volume, as well as surgeon experience with minimally invasive surgery, were associated with a lower risk of surgical failure. Conclusions: LPD is technically safe and feasible, with acceptable rates of morbidity and mortality. Nonetheless, long learning curves, low-volume hospitals, and surgical inexperience are associated with higher rates of complications and mortality.

Synthetic Versus Biological Mesh in Laparoscopic and Open Ventral Hernia Repair (LAPSIS): Results of a Multinational, Randomized, Controlled, and Double-blind Trial

xloma.fota13 shared this article with you from Inoreader
imageObjective: The aim of this study was to investigate the approach (open or laparoscopic) and mesh type (synthetic or biological) in ventral hernias in a clean setting. Summary of Background Data: The level of evidence on the optimal surgical approach and type of mesh in ventral hernia repair is still low. Methods: Patients with a ventral abdominal hernia (diameter 4–10 cm) were included in this double-blind randomized controlled trial across 17 hospitals in 10 European countries. According to a 2 × 2-factorial design, patients were allocated to 4 arms (open retromuscular or laparoscopic intraperitoneal, with synthetic or Surgisis Gold biological mesh). Patients and outcome assessors were blinded to mesh type used. Major postoperative complication rate (hernia recurrence, mesh infection, or reoperation) within 3 years after surgery, was the primary endpoint in the intention-to-treat population. Results: Between September 1st, 2005, and August 7th, 2009, 253 patients were randomized and 13 excluded. Six of 61 patients (9.8%) in the open synthetic mesh arm, 15 of 66 patients (22.7%) in the open biological mesh arm, 7 of 64 patients (10.9%) in the laparoscopic synthetic mesh arm and 17 of 62 patients (27.4%) in the laparoscopic biological mesh arm had a major complication. The use of biological mesh resulted in significantly more complications (P = 0.013), also after adjusting for hernia type, body mass index, and study site. The trial was prematurely stopped due to an unacceptable high recurrence rate in the biological mesh arms. Conclusions: The use of Surgisis Gold biological mesh is not recommended for noncomplex ventral hernia repair. Trial Registration: This trial was registered at controlled-trials.com (ISRCTN34532248).

Simultaneous Versus Delayed Resection for Initially Resectable Synchronous Colorectal Cancer Liver Metastases: A Prospective, Open-label, Randomized, Controlled Trial

xloma.fota13 shared this article with you from Inoreader
imageObjective: To answer whether synchronous colorectal cancer liver metastases (SLM) should be resected simultaneously with primary cancer or should be delayed. Summary Background Data: Numerous studies have compared both strategies. All were retrospective and conclusions were contradictory. Methods: Adults with colorectal cancer and resectable SLM were randomly assigned to either simultaneous or delayed resection of the metastases. The primary outcome was the rate of major complications within 60 days following surgery. Secondary outcomes included overall and disease-free survival. Results: A total of 105 patients were recruited. Eighty-five patients (39 and 46 in the simultaneous- and delayed-resection groups, respectively) were analyzed. The percentage of major perioperative complications did not differ between groups (49% and 46% in the simultaneous- and delayed-resection groups, respectively, adjusted OR 0.84, 95% CI 0.35–2.01; P = 0.70, logistic regression). Complications rates were 28% and 13% (P = 0.08, χ2 test) at colorectal site and 15% and 17% (P = 0.80, χ2 test) at liver site, in simultaneous- and delayed-resection groups, respectively. In the delayed-resection group, 8 patients did not reach the liver resection stage, and this was due to disease progression in 6 cases. After 2 years, overall and disease-free survival tended to be improved in simultaneous as compared with delayed-resection groups (P = 0.05), a tendency which persisted for OS after a median follow-up of 47 months. Conclusions: Complication rates did not appear to differ when colorectal cancer and synchronous liver metastases are resected simultaneously. Delayed resection tended to impair overall survival.

Risk of Acquiring Perioperative COVID-19 During the Initial Pandemic Peak: A Retrospective Cohort Study

xloma.fota13 shared this article with you from Inoreader
imageObjective: To determine the risk of acquiring perioperative COVID-19 infection in previously COVID-19 negative patients. Summary of Background Data: During the initial peak of the COVID-19 pandemic, there was significant concern of hospital acquired COVID-19 infections. Medical centers rapidly implemented systems to minimize perioperative transmission, including routine preoperative testing, patient isolation, and enhanced cleaning. Methods: In this retrospective cohort study, medical records of all adult patients who underwent surgery at our quaternary, acute care hospital between March 15 and May 15, 2020 were reviewed. The risk of preoperatively negative patients developing symptomatic COVID-19 within 2–14 days postoperatively was determined. Surgical characteristics, outcomes, and complications were compared between those with and without acquired perioperative COVID-19 infection. Results: Among 501 negative patients undergoing index surgeries, 9 (1.8%) developed symptomatic COVID-19 in the postoperative period; all occurred before implementation of routine preoperative testing [9/243, 3.7% vs 0/258, 0%, odds ratio (OR): 0.048, P = 0.036]. No patient who was polymerase-chain-reaction negative on the day of surgery (n = 170) developed postoperative infection. Perioperative infection was associated with preoperative diabetes (OR: 3.70, P = 0.042), cardiovascular disease (OR: 3.69, P = 0.043), angiotensin receptor blocker use (OR: 6.58, P = 0.004), and transplant surgery (OR: 11.00, P = 0.002), and multiple complications, readmission (OR: 5.50, P = 0.029) and death (OR: 12.81, P = 0.001). Conclusions: During the initial peak of the COVID-19 pandemic, there was minimal risk of acquiring symptomatic perioperative COVID-19 infection, especially after the implementation of routine preoperative testing. However, perioperative COVID-19 infection was associated with poor postoperative outcome.

Perioperative Morbidity and Mortality of Patients With COVID-19 Who Undergo Urgent and Emergent Surgical Procedures

xloma.fota13 shared this article with you from Inoreader
imageObjective: To evaluate the perioperative morbidity and mortality of patients with COVID-19 who undergo urgent and emergent surgery. Summary Background Data: Although COVID-19 infection is usually associated with mild disease, it can lead to severe respiratory complications. Little is known about the perioperative outcomes of patients with COVID-19. Methods: We examined patients who underwent urgent and emergent surgery at 2 hospitals in New York City from March 17 to April 15, 2020. Elective surgical procedures were cancelled throughout and routine, laboratory based COVID-19 screening was instituted on April 1. Mortality, complications, and admission to the intensive care unit were compared between patients with COVID-19 detected perioperatively and controls. Results: Among 468 subjects, 36 (7.7%) had confirmed COVID-19. Among those with COVID-19, 55.6% were detected preoperatively and 44.4% postoperatively. Before the routine preoperative COVID-19 laboratory screening, 7.7% of cases were diagnosed preoperatively compared to 65.2% after institution of screening (P = 0.0008). The perioperative mortality rate was 16.7% in those with COVID-19 compared to 1.4% in COVID-19 negative subjects [aRR = 9.29; 95% confidence interval (CI), 5.68–15.21]. Serious complications were identified in 58.3% of COVID-19 subjects versus 6.0% of controls (aRR = 7.02; 95%CI, 4.96–9.92). Cardiac arrest, sepsis/shock, respiratory failure, pneumonia, acute respiratory distress syndrome, and acute kidney injury were more common in those with COVID-19. The intensive care unit admission rate was 36.1% in those with COVID-19 compared to 16.4% of controls (aRR = 1.34; 95%CI, 0.86–2.09). Conclusions: COVID-19 is associated with an increased risk for serious perioperative morbidity and mortality. A substantial number of patients with COVID-19 are not identified until after surgery.

Time-varying Reproductive Rates for SARS-CoV-2 and its Implications as a Means of Disease Surveillance on Lockdown Restrictions

xloma.fota13 shared this article with you from Inoreader
imageObjective: To quantify the time-varying reproductive rates for SARS-CoV-2 and its implication in Louisiana. Summary of Background Data: Basic reproductive number (R0) and effective reproductive number (Re or Rt) are 2 measures of the ability of an infectious agent to spread in the environment. They differ in that R0 assumes zero immunity in the population, while Re or Rt accounts for change over time. Reproductive number modeling is influenced by several factors, including serial interval, the time between the onset of symptoms in an infector, and a secondary case. Quantification of the ability of a pathogen to spread is essential in guiding policy. Methods: Here, we construct epidemic curves and calculate daily Rt values for the state of Louisiana and each of its 9 regions. Results: Our results demonstrated variation over both time and geography in calculated R0 and Rt values. Generally, as time has progressed, predicted R0 and Rt values have decreased. In Louisiana, mean Rt was calculated at 3.07 in March and 0.82 by May. A reproductive number less than one is important as it indicates infectious spread will decline with time. The most recent finding of mean Rt = 0.82 is important. It stands in stark contrast to the situation in April when New Orleans, Louisiana, had the highest per capita coronavirus mortality rate in the United States – twice that of New York City and 4 times the rate in Seattle. Conclusion: As locations around the world begin to lift restrictions, monitoring of infectious spread will be essential.

Wounds Inhibit Tumor Growth In Vivo

xloma.fota13 shared this article with you from Inoreader
imageObjective: The aim of this study was to determine the interaction of full thickness excisional wounds and tumors in vivo. Summary of Background Data: Tumors have been described as wounds that do not heal due to similarities in stromal composition. On the basis of observations of slowed tumor growth after ulceration, we hypothesized that full thickness excisional wounds would inhibit tumor progression in vivo. Methods: To determine the interaction of tumors and wounds, we developed a tumor xenograft/allograft (human head and neck squamous cell carcinoma SAS/mouse breast carcinoma 4T1) wound mouse model. We examined tumor growth with varying temporospatial placement of tumors and wounds or ischemic flap. In addition, we developed a tumor/wound parabiosis model to understand the ability of tumors and wounds to recruit circulating progenitor cells. Results: Tumor growth inhibition by full thickness excisional wounds was dose-dependent, maintained by sequential wounding, and relative to distance. This effect was recapitulated by placement of an ischemic flap directly adjacent to a xenograft tumor. Using a parabiosis model, we demonstrated that a healing wound was able to recruit significantly more circulating progenitor cells than a growing tumor. Tumor inhibition by wound was unaffected by presence of an immune response in an immunocompetent model using a mammary carcinoma. Utilizing functional proteomics, we identified 100 proteins differentially expressed in tumors and wounds. Conclusion: Full thickness excisional wounds have the ability to inhibit tumor growth in vivo. Further research may provide an exact mechanism for this remarkable finding and new advances in wound healing and tumor biology.
