RESUMO
BACKGROUND: Albumin continues to be used routinely by cardiac anaesthesiologists perioperatively despite lack of evidence for improved outcomes. The Multicenter Perioperative Outcomes Group (MPOG) data ranked our institution as one of the highest intraoperative albumin users during cardiac surgery. Therefore, we designed a quality improvement project (QIP) to introduce a bundle of interventions to reduce intraoperative albumin use in cardiac surgical patients. METHODS: Our institutional MPOG data were used to analyse the FLUID-01-C measure that provides the number of adult cardiac surgery cases where albumin was administered intraoperatively by anaesthesiologists from 1 July 2019 to 30 June 2022. The QIP involved introduction of the following interventions: (1) education about appropriate albumin use and indications (January 2021), (2) email communications reinforced with OR teaching (March 2021), (3) removal of albumin from the standard pharmacy intraoperative medication trays (April 2021), (4) grand rounds presentation discussing the QIP and highlighting the interventions (May 2021) and (5) quarterly provider feedback (starting July 2021). Multivariable segmented regression models were used to assess the changes from preintervention to postintervention time period in albumin utilisation, and its total monthly cost. RESULTS: Among the 5767 cardiac surgery cases that met inclusion criteria over the 3-year study period, 16% of patients received albumin intraoperatively. The total number of cases that passed the metric (albumin administration was avoided), gradually increased as our interventions went into effect. Intraoperative albumin utilisation (beta=-101.1, 95% CI -145 to -56.7) and total monthly cost of albumin (beta=-7678, 95% CI -10712 to -4640) demonstrated significant decrease after starting the interventions. CONCLUSIONS: At a single academic cardiac surgery programme, implementation of a bundle of simple and low-cost interventions as part of a coordinated QIP were effective in significantly decreasing intraoperative use of albumin, which translated into considerable costs savings.

The demographic development suggests a dramatic growth in the number of elderly patients undergoing surgery in Europe. Most red blood cell transfusions (RBCT) are administered to older people, but little is known about perioperative transfusion practices in this population. In this secondary analysis of the prospective observational multicentre European Transfusion Practice and Outcome Study (ETPOS), we specifically evaluated intraoperative transfusion practices and the related outcomes of 3149 patients aged 65 years and older. Enrolled patients underwent elective surgery in 123 European hospitals, received at least one RBCT intraoperatively and were followed up for 30 days maximum. The mean haemoglobin value at the beginning of surgery was 108 (21) g/l, 84 (15) g/l before transfusion and 101 (16) g/l at the end of surgery. A median of 2 [1-2] units of RBCT were administered. Mostly, more than one transfusion trigger was present, with physiological triggers being preeminent. We revealed a descriptive association between each intraoperatively administered RBCT and mortality and discharge respectively, within the first 10 postoperative days but not thereafter. In our unadjusted model the hazard ratio (HR) for mortality was 1.11 (95% CI: 1.08-1.15) and the HR for discharge was 0.78 (95% CI: 0.74-0.83). After adjustment for several variables, such as age, preoperative haemoglobin and blood loss, the HR for mortality was 1.10 (95% CI: 1.05-1.15) and HR for discharge was 0.82 (95% CI: 0.78-0.87). Pre-operative anaemia in European elderly surgical patients is undertreated. Various triggers seem to support the decision for RBCT. A closer monitoring of elderly patients receiving intraoperative RBCT for the first 10 postoperative days might be justifiable. Further research on the causal relationship between RBCT and outcomes and on optimal transfusion strategies in the elderly population is warranted. A thorough analysis of different time periods within the first 30 postoperative days is recommended.

BACKGROUND: Axillary lymph node dissection (ALND) remains the standard of care in breast cancer patients with positive sentinel lymph node (SLN). However, approximately 40-60% of patients with positive SLNs have not developed to non-SLN metastasis and ALND seems to be an overtreatment. The purpose of this study was to analyze predictors and define a specific cut-off of total tumor load (TTL) of CK19 that can be used as a predictive factor of non-SLN metastasis in early breast cancer patients. MATERIALS AND METHODS: The records of 238 patients with cT1-3N0 breast cancer who had an intraoperative SLN evaluation performed through One-Step nucleic acid (OSNA) assay at Songklanagarind Hospital between 1 January 2015 and 31 December 2019 were examined. Univariate and Multivariate analysis was used to identify clinicopathologic features in SLN-positive patients that predict metastasis to non-SLNs. Finally, receiver operative characteristics (ROC) curves were used to choose an optimal TTL cut-off value. RESULTS: Of a total of 110 patients who had a positive SLN, only 48 (43.64%) were found to have positive nodes in non-SLN. Multivariate analysis revealed that lymphovascular invasion, type of SLN metastasis and SLN TTL (copies/µL) were independent predictors of positive non-SLNs. TTL cut-off value was 19,000 copies/µL, with an AUC of 0.838 with 72.7% sensitivity and 84.7% specificity to predict non-SLN metastasis. CONCLUSIONS: The likelihood of positive non-SLNs in patients who showed a positive SLN correlates with lymphovascular invasion, type of SLN metastasis and SLN TTL (copies/µL). Our result revealed that the patients with a SLN TTL ≥19,000 copies/µl continue to attract the recommendation to proceed with ALND. This cut-off value can then help clinicians to assess which patients would benefit from ALND.

Importance: Postoperative ileus is common after abdominal surgery, and small clinical studies have reported that intraoperative administration of dexmedetomidine may be associated with improvements in postoperative gastrointestinal function. However, findings have been inconsistent and study samples have been small. Further examination of the effects of intraoperative dexmedetomidine on postoperative gastrointestinal function is needed. Objective: To evaluate the effects of intraoperative intravenous dexmedetomidine vs placebo on postoperative gastrointestinal function among older patients undergoing abdominal surgery. Design, Setting, and Participants: This multicenter, double-blind, placebo-controlled randomized clinical trial was conducted at the First Affiliated Hospital of Anhui Medical University in Hefei, China (lead site), and 12 other tertiary hospitals in Anhui Province, China. A total of 808 participants aged 60 years or older who were scheduled to receive abdominal surgery with an expected surgical duration of 1 to 6 hours were enrolled. The study was conducted from August 21, 2018, to December 9, 2019. Interventions: Dexmedetomidine infusion (a loading dose of 0.5 µg/kg over 15 minutes followed by a maintenance dose of 0.2 µg/kg per hour) or placebo infusion (normal saline) during surgery. Main Outcomes and Measures: The primary outcome was time to first flatus. Secondary outcomes were postoperative gastrointestinal function measured by the I-FEED (intake, feeling nauseated, emesis, physical examination, and duration of symptoms) scoring system, time to first feces, time to first oral feeding, incidence of delirium, pain scores, sleep quality, postoperative nausea and vomiting, hospital costs, and hospital length of stay. Results: Among 808 patients enrolled, 404 were randomized to receive intraoperative dexmedetomidine, and 404 were randomized to receive placebo. In total, 133 patients (60 in the dexmedetomidine group and 73 in the placebo group) were excluded because of protocol deviations, and 675 patients (344 in the dexmedetomidine group and 331 in the placebo group; mean [SD] age, 70.2 [6.1] years; 445 men [65.9%]) were included in the per-protocol analysis. The dexmedetomidine group had a significantly shorter time to first flatus (median, 65 hours [IQR, 48-78 hours] vs 78 hours [62-93 hours], respectively; P < .001), time to first feces (median, 85 hours [IQR, 68-115 hours] vs 98 hours [IQR, 74-121 hours]; P = .001), and hospital length of stay (median, 13 days [IQR, 10-17 days] vs 15 days [IQR, 11-18 days]; P = .005) than the control group. Postoperative gastrointestinal function (as measured by the I-FEED score) and delirium incidence were similar in the dexmedetomidine and control groups (eg, 248 patients [72.1%] vs 254 patients [76.7%], respectively, had I-FEED scores indicating normal postoperative gastrointestinal function; 18 patients [5.2%] vs 12 patients [3.6%] had delirium on postoperative day 3). Conclusions and Relevance: In this randomized clinical trial, the administration of intraoperative dexmedetomidine reduced the time to first flatus, time to first feces, and length of stay after abdominal surgery. These results suggest that this therapy may be a viable strategy to enhance postoperative recovery of gastrointestinal function among older adults.

BACKGROUND: Postoperative surgical site infection is a major source of morbidity after pancreatic head resections, and data suggest bacterobilia as a leading cause. Some centers use intraoperative bile duct cultures to guide postoperative antimicrobial prophylaxis. This prospective study evaluates culture differences between traditional bile duct swab versus bile duct aspiration intraoperative samples. METHODS: Prospective patients undergoing pancreatic head resection with both bile duct swab and bile duct aspiration were included. Cultures were reviewed for organism characteristics. Any growth of organisms was considered a positive culture. Bile duct swab yield and characteristics were compared with bile duct aspiration. Postoperative surgical site infection complications were compared to bile duct culture results. RESULTS: Fifty patients were included. Bile duct aspiration resulted in a significantly higher median number of organisms compared to bile duct swab (6 vs 3; P < .001). There were no differences in the number of patients (37 vs 33) having positive bile duct aspiration and bile duct swab cultures (P = .385). Anaerobic cultures (not possible with bile duct swab) were positive in 21 patients with bile duct aspiration. A total of 37 (74%) patients had preoperative biliary stenting, which highly associated (P < .001) with positive cultures. Bile duct culture organisms correlated with postoperative surgical site infection in 12/17 (71%) patients. CONCLUSION: Use of bile duct aspiration improves intraoperative bile duct culture organism yield over bile duct swab and may improve tailoring of antibiotics in patients undergoing pancreatic head resection.

INTRODUCTION: Previous iterations of National Blood Collection and Utilization Survey (NBCUS) have demonstrated declines in blood collection and transfusion in the United States since 2008, including declines of 3.0% and 6.1% in red blood cell (RBC) collections and transfusions between 2015 and 2017, respectively. This study describes results of the 2019 NBCUS. METHODS: The survey was distributed to all US blood collection centers, all hospitals performing ≥1000 surgeries annually, and a 40% random sample of hospitals performing 100-999 surgeries annually. Weighting and imputation were used to generate national estimates for units of blood and components collected, distributed, transfused, and outdated. RESULTS: In 2019, 11,590,000 RBC units were collected (95% confidence interval [CI], 11,151,000-12,029,000 units), a 5.1% decrease compared with 2017, while 10,852,000 RBC units were transfused (95% CI, 10,444-11,259 units), a 2.5% increase from 2017. Between 2017 and 2019, platelet distributions (2,508,000 units; 95% CI, 2,375,000-2,641,000 units) decreased by 2.0%, and plasma distributions (2,679,000 units; 95% CI, 2,525,000-2,833,000 units) decreased by 16.5%. During the same time period, platelet transfusions (2,243,000 units; 95% CI, 1,846,000-2,147,000 units) increased by 15.8% and plasma transfusions (2,185,000 units; 95% CI, 2,068,000-2,301,000 units) decreased by 8.0%. CONCLUSION: Utilization of RBC in the United States might have reached a nadir. Between 2017 and 2019, RBC collections declined while RBC transfusions did not significantly change, suggesting a narrowing between blood supply and demand. Monitoring national blood collection and utilization data is integral to understanding trends in blood supply safety and availability.

OBJECTIVE: It remains unclear whether transfusion strategies during orthopedic surgery and infection are related. The purpose of this study is to evaluate whether liberal blood transfusion strategies contribute to infection risk in orthopedic patients by analyzing randomized controlled trials (RCTs). METHODS: RCTs with liberal versus restrictive red blood cell (RBC) transfusion strategies were identified by searching PubMed, Embase, the Cochrane Central Register of Controlled Trials from their inception to July 2019. Ten studies with infections as outcomes were included in the final analysis. According to the Jadad scale, all studies were considered to be of high quality. RESULTS: Ten trials involving 3938 participants were included in this study. The pooled risk ratio (RR) for the association between liberal transfusion strategy and infection was 1.34 (95% confidence intervals [CI], 0.94-1.90; Pâ=â.106). The sensitivity analysis indicated unstable results, and no significant publication bias was observed. CONCLUSION: This pooled analysis of RCTs demonstrates that liberal transfusion strategies in orthopedic patients result in a nonsignificant increase in infections compared with more restrictive strategies. The conclusions are mainly based on retrospective studies and should not be considered as recommendation before they are supported by larger scale and well-designed RCTs.

BACKGROUND: There is a growing need to identify which bits of information are most valuable for healthcare providers. The aim of this study was to search for the highest impact variables in predicting postsurgery length of stay (LOS) for patients who undergo coronary artery bypass grafting (CABG). MATERIALS AND METHODS: Using a single institution's Society of Thoracic Surgeons (STS) Registry data, 2121 patients with elective or urgent, isolated CABG were analyzed across 116 variables. Two machine learning techniques of random forest and artificial neural networks (ANNs) were used to search for the highest impact variables in predicting LOS, and results were compared against multiple linear regression. Out-of-sample validation of the models was performed on 105 patients. RESULTS: Of the 10 highest impact variables identified in predicting LOS, four of the most impactful variables were duration intubated, last preoperative creatinine, age, and number of intraoperative packed red blood cell transfusions. The best performing model was an ANN using the ten highest impact variables (testing sample mean absolute error (MAE) = 1.685 d, R2 = 0.232), which performed consistently in the out-of-sample validation (MAE = 1.612 d, R2 = 0.150). CONCLUSION: Using machine learning, this study identified several novel predictors of postsurgery LOS and reinforced certain known risk factors. Out of the entire STS database, only a few variables carry most of the predictive value for LOS in this population. With this knowledge, a simpler linear regression model has been shared and could be used elsewhere after further validation.

BACKGROUND: This study examined the accuracy and pitfalls associated with frozen section diagnosis of primary ovarian tumors and ovarian metastases based on the 2014 World Health Organization classification (WHO) criteria and proposed improvements from a pathologist's perspective. METHODS: We microscopically reviewed 871 cases of primary ovarian tumor (N = 802) and ovarian metastasis (N = 69) and compared the results of frozen sections with the final diagnosis. Malignant potential concordance (benign, borderline, or malignant) and specific discordant diagnosis rates were analyzed. Finally, we conducted a unique literature review of specific diagnostic errors in the frozen section diagnosis of primary ovarian tumors. RESULTS: Of 802 primary ovarian tumors, 50 (6.2%) cases showed discordant diagnoses in which mucinous carcinoma (40.5%), low-grade serous carcinoma (LGSC; 31.3%), and mucinous borderline tumor (18.4%) were frequently misinterpreted. Of 69 ovarian metastases, all 4 cases of low-grade appendiceal mucinous neoplasm (LAMN) were misdiagnosed as primary ovarian mucinous tumor. A literature review revealed that mucinous/serous borderline tumor or carcinoma accounted for approximately 70% of 217 reported discordant diagnoses. CONCLUSION: In the present study, the concordance rate of malignant potential of the tumor was comparable to that previously reported. Even in the 2014 WHO classification, primary ovarian mucinous borderline tumor/carcinoma and LGSC still comprised the majority of discordant cases. Grossing methods that reduce sampling error are required. LAMN was frequently misinterpreted as a benign or borderline ovarian mucinous tumor. To prevent this error, a differential algorithm integrating clinical information and gross findings should be developed.

PURPOSE: Anatomical pulmonary resection, such as lobectomy, is a common procedure. Staplers play an important role in dividing an incomplete interlobular fissure, especially in thoracoscopic surgery. This study evaluates the effectiveness of a powered stapler for reducing the need for intraoperative fibrin glue and the incidence of air leakage after radical pulmonary resection. METHODS: The subjects of this retrospective study were 478 patients who underwent radical pulmonary resection. Propensity score analysis generated two matched pairs of 177 patients treated using powered and manual staplers, respectively. RESULTS: The need for fibrin glue intraoperatively during radical pulmonary resection was significantly less in the powered-stapler group (47.5%) than in the manual-stapler group (58.8%, p = 0.033). The incidence of postoperative air leakage following radical pulmonary resection was also significantly lower in the powered-stapler group (2.8%) than in the manual-stapler group (10.7%, p = 0.003). Logistic regression analysis identified use of the powered stapler as a factor independently associated with both non-use of fibrin glue intraoperatively (odds ratio, 0.63; p = 0.040) and no postoperative air leakage (odds ratio, 0.26; p = 0.010). CONCLUSION: Using a powered stapler to divide the incomplete interlobular fissure decreased the need for additional intraoperative management using fibrin glue and reduced postoperative air leakage in radical pulmonary resection.

BACKGROUND: Thyroid lobectomy is the preferred option for small, unifocal papillary thyroid carcinoma. Involvement of the central neck lymph nodes is an indication for total thyroidectomy plus central neck dissection. We aimed to verify if frozen section examination of ipsilateral central neck nodes can identify the subgroup of patients scheduled for thyroid lobectomy intraoperatively who could benefit of more extensive initial operative treatment. METHODS: Ninety-four consenting patients with clinically unifocal cN0 papillary thyroid carcinoma underwent thyroid lobectomy plus ipsilateral central neck dissection with frozen section examination. If the frozen section examination was positive for metastases, a completion thyroidectomy and a bilateral central neck dissection were accomplished during the same procedure. RESULTS: Frozen section examination identified occult nodal metastases in 25 of the 94 patients who then underwent immediate completion thyroidectomy and bilateral central neck dissection. Overall, central neck node metastases were found at final histology in 35 cases: occult micrometastases were observed in additional 9 patients and nodal metastases ≥2 mm in additional 1 patient. CONCLUSION: Intraoperative assessment of nodal status obtained with ipsilateral central neck dissection and frozen section examination is able to change the extent of thyroidectomy in about one-fourth of patients scheduled for thyroid lobectomy. Frozen section examination appears a safe and effective strategy to decrease the need of a second-step completion procedure and, theoretically, the risk of recurrence.

INTRODUCTION: Perioperative pain may have deleterious effects for all patients. We aim to examine disparities in pain management for children in the perioperative period to understand whether any racial and ethnic groups are at increased risk of poor pain control. METHODS: Medical records from children ≤ 18 years of age who underwent surgery from May 2014 to May 2018 were reviewed. The primary outcome was total intraoperative morphine equivalents. The secondary outcomes were intraoperative non-opioid analgesic administration and first conscious pain score. The exposure was race and ethnicity. The associations of race and ethnicity with outcomes of interest were modeled using linear or logistic regression, adjusted for preselected confounders and covariates. Bonferroni corrections were made for multiple comparisons. RESULTS: A total of 21,229 anesthetics were included in analyses. In the adjusted analysis, no racial and ethnic group received significantly more or less opioids intraoperatively than non-Hispanic (NH) whites. Asians, Hispanics, and Pacific Islanders were estimated to have significantly lower odds of receiving non-opioid analgesics than NH whites: odds ratio (OR) = 0.83 (95% confidence interval (CI): 0.70, 0.97); OR = 0.84 (95% CI: 0.74, 0.97), and OR = 0.53 (95% CI: 0.33, 0.84) respectively. Asians were estimated to have significantly lower odds of reporting moderate-to-severe pain on awakening than NH whites: OR = 0.80 (95% CI: 0.66, 0.99). CONCLUSIONS: Although children of all races and ethnicities investigated received similar total intraoperative opioid doses, some were less likely to receive non-opioid analgesics intraoperatively. Asians were less likely to report moderate-severe pain upon awakening. Further investigation may delineate how these differences lead to disparate patient outcomes and are influenced by patient, provider, and system factors.

INTRODUCTION: Sentinel node (SN) assessment via frozen section (FS) has declined since the publication of Z0011 which modified the management of a specific group of patients with positive SN. The risk of misleading the surgeons to a preventable ALND and the cost are among the main factors for that. The aim of our study is to assess the value of FS in the post Z0011. MATERIAL AND METHODS: 244 patients out of 434 were eligible for an upfront SLNB. Based on the final histology and the clinical data we selected the eligible for breast conserving surgery patients (55.4%). 78 patients had positive SN and 26 of them fulfilled the criteria of Z0011. We assessed the false negative findings, the impact on the management and the indications and value of FS in the post Z0011 era. RESULTS: Overall, there were 12 FN cases out of which 7 were macrometastases (8.97%). Only in one case there were > 2 positive LN and 3 patients needed mastectomy. The remaining cases fulfilled the criteria of Z0011 and needed no further surgery hence in 96.1% of the cases the axillary status was correctly assessed via FS and the reoperation rate was 1.2%. On the contrary, if FS was not used, at least 21.3% of the patents would have needed reoperation based on the today's guidelines. DISCUSSION: We believe FS is still valuable and may spare a significant percentage of patients from a second operation (SNB) without leading to axillary overtreatment if used wisely.

BACKGROUND: Mannitol and furosemide have been used as diuretics intraoperatively to facilitate early renal allograft function and reduce delayed graft function. As the evidence of any efficacy of these agents is limited, we sought to characterize the use of diuretics among transplant surgeons. METHODS: An anonymous online survey was sent to all Canadian transplant programs where kidney transplants are routinely performed. Questions were related to the use and indications for mannitol and furosemide. Responses were collected and analyzed as counts and percentages of respondents. We used χ2 analysis to assess the relationship between demographic factors and survey responses. RESULTS: Thirty-five surgeons completed the survey (response rate 50%). Seventy per cent of respondents reported performing 26 or more transplants per year, 88% had formal transplant fellowship training and 67% indicated that they currently train fellows. Only 24% and 12% reported believing that delayed graft function is reduced by mannitol and furosemide use, respectively. However, 73% routinely gave mannitol to patients and 53% routinely gave furosemide. The most common justification given for mannitol use was to induce diuresis (54%); 37% of respondents reported using mannitol because of training dogma. Likewise, 57% used furosemide for diuresis, with 23% reporting that their use of this agent was based on dogma. No relationship emerged between fellowship training, case volume or training program status and the use of any agent. Interestingly, 71% of respondents indicated that a randomized controlled trial evaluating the utility of intraoperative diuretics is needed and that they were interested in participating in such a trial. CONCLUSION: Use of intraoperative diuretics and the rationale for their use vary among surgeons. A substantial proportion of surgeons use these medications on the basis of dogma alone. A randomized controlled trial is needed to clarify the role of intraoperative diuretics in kidney transplant surgery.
CONTEXTE: On a utilisé le mannitol et le furosémide comme diurétiques peropératoires pour stimuler le fonctionnement précoce de l'allogreffe rénale et réduire le retard de fonctionnement du greffon. Comme les données probantes quant à l'efficacité de ces agents sont limitées, nous avons voulu caractériser l'utilisation des diurétiques chez les chirurgiens qui effectuent ces transplantations. MÉTHODES: Un sondage anonyme en ligne a été envoyé à tous les programmes de greffe canadiens où des greffes rénales sont couramment effectuées. Les questions avaient trait à l'utilisation et aux indications du mannitol et du furosémide. Les réponses ont été recueillies et analysées sous forme de nombres et de pourcentages des répondants. Le test du χ2 a été utilisé pour évaluer le lien entre les facteurs démographiques et les réponses au sondage. RÉSULTATS: Trente-cinq chirurgiens ont répondu au sondage (taux de réponse 50 %). Soixante-dix pour cent des répondants ont indiqué effectuer annuellement 26 greffes ou plus, 88 % avaient suivi une spécialisation formelle pour l'exécution des greffes et 67 % ont dit être en cours de spécialisation. Seulement 24 % et 12 % respectivement ont dit croire que le mannitol et le furosémide permettent de réduire le retard de fonctionnement du greffon. Toutefois, 73 % et 53 % respectivement administraient de routine du mannitol et du furosémide aux patients. La justification la plus fréquente de l'utilisation du mannitol était d'induire la diurèse (54 %); 37 % des répondants ont dit utiliser le mannitol parce que c'est ce qu'on leur a enseigné durant leur formation. De même, 57 % utilisaient le furosémide pour la diurèse, dont 23 % disaient que c'est ce qu'on leur avait enseigné durant leur formation. Aucun lien n'est ressorti entre la spécialisation, le volume de cas ou le statut à l'égard du programme de formation et l'utilisation d'un agent quelconque. Fait à noter, 71 % des répondants ont indiqué qu'un essai randomisé et contrôlé sur l'utilité des diurétiques peropératoires serait nécessaire et qu'ils y participeraient volontiers. CONCLUSION: L'utilisation de diurétiques peropératoires et la justification de leur utilisation varient d'un chirurgien à l'autre. En majeure partie, les chirurgiens utilisent ces médicaments sur la base des notions théoriques seulement. Un essai randomisé et contrôlé s'impose pour clarifier le rôle des diurétiques peropératoires dans la greffe rénale.

RATIONALE: Giant intra-abdominal liposarcomas weighing over 20âkg often increase the intra-abdominal pressure (IAP), which has severe effects on the cardiovascular and respiratory systems. Abdominal compartment syndrome is defined typically as the combination of a raised IAP of 20 mm Hg or higher and new onset of organ dysfunction or failure. The anesthetic management and perioperative management are very challenging. PATIENTS CONCERNS: We presented 2 patients with rare giant growing liposarcoma of the abdomen, weighing 21âkg and over 35âkg, respectively. Circulatory management was particularly difficult in the first case, while respiratory management and massive blood loss was very challenging in the second one. DIAGNOSIS: With a computed tomography scan and peritoneal-to-abdominal height ratio measurement, preoperatively the risk of developing intra-abdominal hypertension and abdominal compartment syndrome was recognized early in each patient. The inferior vena cava and right atrium of the first patient was compressed and malformed due to the uplifted diaphragm, while there was severe decreased lung volume and increased airway resistance, because of rare giant retroperitoneal liposarcomas in the second case. Histologic examination revealed dedifferentiated liposarcoma in both cases. INTERVENTIONS: Both of the patients underwent resection surgery with multiple monitoring; transesophageal echocardiography monitoring in the first case and pressure-controlled ventilation volume guaranteed mechanical ventilation mode in both cases. OUTCOMES: Intraoperatively and postoperatively no cardiopulmonary complications in both patients. The first patient was discharged without any complications on postoperative day 10, and the second patient underwent another surgery because of anastomotic leakage resulting from bowel resection. LESSONS: Multiple monitorings, in particular transesophageal echocardiography should be considered in patients with increased IAP due to a giant mass, while an appropriate lung protection ventilation strategy is crucial in these patients.

Up to now, Italy is one of the European centers with the most active Coronavirus cases with 233,836 positive cases and 33,601 total deaths as of June 3rd. During this pandemic and dramatic emergency, Italian hospitals had also to face neoplastic pathologies, that still afflict the Italian population, requiring urgent surgical and oncological treatment. In our Cancer Center Hospital, the high volume of surgical procedures have demanded an equally high volume of intraoperative pathological examinations, but also posed an additional major challenge for the safety of the staff involved. The current commentary reports our experience in the past two months (since March 9th) for a total of 1271 frozen exams from 893 suspect COVID-19 patients (31 confirmed).

BACKGROUND: Hand-offs in the operating room contribute to poor communication, reduced team function, and may be poorly coordinated with other activities. Conversely, they may represent a missed opportunity for improved communication. We sought to better understand the coordination and impact of intraoperative hand-offs. METHODS: We prospectively audio-video (AV) recorded 10 operations and evaluated intraoperative hand-offs. Data collected included percentage of time team members were absent due to breaks, relationships between hand-offs and intraoperative events (incision, surgical counts), and occurrences of simultaneous hand-offs. We also identified announcement that a hand-off had occurred and anchoring, in which team members not involved in the hand-off participated and provided information. RESULTS: Spanning 2919 min of audio-video data, there were 74 hand-offs (range, 4-14 per case) totaling 225.2 min, representing 7.7% of time recorded. Thirty-two (45.1%) hand-offs were interrupted or delayed because of competing activities; eight hand-offs occurred during an instrument or laparotomy pad count. Six cases had simultaneous hand-offs; two cases had two episodes of simultaneous hand-offs. Eight hand-offs included an announcement. Seven included anchoring. Evaluating both temporary and permanent hand-offs, one or more original team members was absent for 40.7% of time recorded and >one team member was absent for 20.5% of time recorded. CONCLUSIONS: Intraoperative hand-offs are frequent and not well coordinated with intraoperative events including counts and other hand-offs. Anchoring and announced hand-offs occurred in a small proportion of cases. Future work must focus on optimizing timing, content, and participation in intraoperative hand-offs.

BACKGROUND: Postoperative infectious complications after a pancreaticoduodenectomy remain a significant cause of morbidity. Studies have demonstrated that a preoperative biliary stent increases the risk of postoperative infectious complications. Few studies have investigated the specific preoperative biliary stent bacterial sensitivities to preoperative antibiotics and the effect on infectious complications. The goal of this study was to investigate if the presence of a preoperative biliary stent increases the risk of postoperative infectious complications in patients undergoing a pancreaticoduodenectomy. Additionally, we aimed to investigate biliary stent culture sensitivities to preoperative antibiotics and determine if those sensitivities impacted postoperative infectious complications after a pancreaticoduodenectomy. METHODS: A retrospective chart review of patients who had undergone a pancreaticoduodenectomy at a single institution tertiary care center from 2007 to 2018 was performed. Perioperative variables including microbiology cultures from biliary stents were collected and analyzed. RESULTS: A total of 244 patients underwent a pancreaticoduodenectomy. A preoperative biliary stent was present in 45 (18%) patients. Infectious complications occurred in 25% of those patients with a preoperative biliary stent, and 19% of those without (P = .37). Of those patients with a stent that was cultured intraoperatively, 92% grew bacteria and 61% of those were resistant to the preoperative antibiotics administered. Of the patients with a preoperative biliary stent and bacteria resistant to the preoperative antibiotics, 17% developed a postoperative infectious complication, compared with 20% if the bacteria cultured was susceptible to the preoperative antibiotics (P = .64). CONCLUSION: Infectious complications after pancreaticoduodenectomy are a significant cause of morbidity. Stent bacterial sensitivities to preoperative antibiotics did not reduce the postoperative infectious complications in the preoperative biliary stent group suggesting a multifactorial cause of infections.

BACKGROUND: Preoperative and/or intraoperative traction have been proposed as adjunctive methods to limit complications associated with growth-friendly instrumentation for early-onset scoliosis (EOS). By gradually correcting the deformity before instrumentation, traction can, theoretically, allow for better overall correction without the complications associated with the immediate intraoperative correction. The purpose of this multicenter study was to investigate the association between preoperative/intraoperative traction and complications following growth-friendly instrumentation for EOS. METHODS: Patients with EOS who underwent growth rod instrumentation before 2017 were identified from 2 registries. Patients were divided into 2 groups: preoperative traction group versus no preoperative traction group. A subgroup analysis was done to compare intraoperative traction only versus no traction. Data was collected on any postoperative complication from implantation to up to 2 years postimplantation. RESULTS: Of 381 patients identified, 57 (15%) and 69 (18%) patients received preoperative and intraoperative traction, respectively. After adjusting for etiology and degree of kyphosis, there was no evidence to suggest that preoperative halo traction reduced the risk of any complication following surgical intervention. Although not statistically significant, a subgroup analysis of patients with severe curves demonstrated a trend toward a markedly reduced hardware failure rate in patients undergoing preoperative halo traction [preoperative traction: 1 (3.1%) vs. no preoperative traction: 11 (14.7%), P=0.083]. Nonidiopathic, hyperkyphotic patients treated with intraoperative traction were 61% less likely to experience any postoperative complication (P=0.067) and were 74% (P=0.091) less likely to experience an unplanned return to the operating room when compared with patients treated without traction. CONCLUSIONS: This multicenter study with a large sample size provides the best evidence to date of the association between the use of traction and postoperative complications. Our results justify the need for future Level I studies aimed at characterizing the complete benefit and risk profile for the use of traction in surgical intervention for EOS. LEVEL OF EVIDENCE: Level III.

OBJECTIVE: To evaluate access to the technologies and education needed to perform minimally invasive spine surgery (MISS) in Latin America. METHODS: We designed a questionnaire to evaluate surgeons' practice characteristics, access to different technologies, and training opportunities for MISS techniques. The survey was sent to members and registered users of AO Spine Latin from January 6-20, 2020. The major variables studied were nationality, specialty (orthopedics or neurosurgery), level of hospital (primary, secondary, tertiary), number of surgeries performed per year by the spine surgeon, types of spinal pathologies commonly managed, and number of MISS performed per year. Other variables involved specific access to different technologies: intraoperative fluoroscopy, percutaneous screws, cages, tubular retractors, microscopy, intraoperative computed tomography, neuronavigation imaging, and bone morphogenetic protein. Finally, participants were asked about main obstacles to performing MISS and their access to education on MISS techniques in their region. RESULTS: The questionnaires were answered by 306 members of AO Spine Latin America across 20 different countries. Most answers were obtained from orthopedic surgeons (57.8%) and those with over 10 years of experience (42.4%). Most of the surgeons worked in private practice (46.4%) and performed >50 surgeries per year (44.1%), but only 13.7% performed >50 MISS per year, mainly to manage degenerative pathologies (87.5%). Most surgeons always had access to fluoroscopy (79%). Only 26% always had access to percutaneous screws, 24% to tubular retractors, 34.3% to cages (anterior lumbar interbody fusion, lateral lumbar interbody fusion, or transforaminal lumbar interbody fusion), and 43% to microscopy. Regarding technologies, 71% reported never having access to navigation, 83% computed tomography, and 69.3% bone morphogenetic protein. The main limitations expressed for widely used MISS technologies were the high implant costs (69.3%) and high navigation costs (49.3%). Most surgeons claimed access to online education activities (71%), but only 44.9% reported access to face-to-face events and 28.8% to hands-on activities, their limited access largely because the courses were expensive (62.7%) or few courses were available on MISS in their region (51.3%). CONCLUSIONS: Most surgeons in Latin America have limited resources to perform MISS, even in private practice. The main constraints are implant costs, access to technologies, and limited face-to-face educational opportunities.
