Early postoperative COVID infection is associated with significantly increased risk of venous thromboembolism after metabolic and bariatric surgery.

BACKGROUND: Patients who undergo metabolic and bariatric surgery (MBS) are at risk for thromboembolism. Patients are susceptible to coronavirus throughout the perioperative period, which also has a well-known association with thrombotic complications. OBJECTIVES: To identify and define the association between venous thromboembolism (VTE) and postoperative coronavirus diagnosis in bariatric surgery patients. SETTING: United States. METHODS: We conducted a retrospective cohort study using the MBS Accreditation and Quality Improvement Program (MBSAQIP) 2021 database to analyze the incidence of VTE within 30 days of surgery. VTE was a composite variable defined as either postoperative pulmonary embolism or postoperative venous thrombus requiring treatment. Cohorts were stratified by whether the patient was diagnosed with postoperative coronavirus. We created a multivariable logistic regression model to determine the adjusted odds of postoperative VTE based on various factors. Additionally, we conducted subset analyses of sleeve gastrectomy and Roux-en-Y bypass cases, the 2 most frequent bariatric operations in the United States. RESULTS: Patients diagnosed with postoperative coronavirus were significantly more likely to develop postoperative VTE (1.1% versus .3%, P < .001). In our logistic regression model, the adjusted odds of postoperative VTE for patients with postoperative coronavirus was 3.55 (95% CI: 2.15-5.87, P < .001). For patients who underwent Roux-en-Y bypass, the adjusted odds was even greater at 5.69 (95% CI: 2.76-11.70, P < .001). CONCLUSIONS: Early postoperative coronavirus infection after MBS is associated with higher odds of postoperative VTE. This persisted on subset analyses of the 2 most common procedures and appeared particularly important for Roux-en-Y bypass. COVID infection after MBS may warrant prolonged VTE prophylaxis.

The Impact of Trainee Involvement on Outcomes in Metabolic and Bariatric Surgery.

BACKGROUND: The number of bariatric operations performed in the USA rises annually. Trainee exposure to this field is necessary to ensure competency in future surgical generations. However, the safety of trainee involvement of these operations has been called into question. OBJECTIVES: The aim of our study is to describe differences in outcomes between trainees and non-trainees as first assistants (FA) in sleeve gastrectomy (SG). SETTING: The Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database METHODS: Patients from the MBSAQIP database who underwent primary SG from 2015 to 2020 were identified. Statistical analysis included two-tailed t-tests and χ2-tests to evaluate the impact of trainees (residents and fellows) compared to non-trainees on post-operative morbidity and operative time. RESULTS: Of the 559,324 cases, 25.8% were performed with trainees as FA. Operative length was 27.9% longer in trainee cases. In the trainee group, there was a higher risk of conversion to open procedure (OR 1.32), readmission (OR 1.19), and specific complications (cardiac arrest, myocardial infarction, progressive renal insufficiency, pulmonary embolism, sepsis, transfusion, intubation, UTI, VTE, ICU admission, and reintervention), though overall rates were < 1% in each group. Non-trainees had a higher rate of septic shock (OR 1.4). No significant difference was seen in all other perioperative outcomes. CONCLUSION: Trainee involvement in SG leads to longer operative times without a clinically significant increase in morbidity and mortality. Such findings should be used to counsel patients and shape expectations for surgeons and hospitals. A focused bariatric surgery trainee curriculum may lessen this gap.

Factors Related to Bleeding and Leak Rates After Robotic Sleeve Gastrectomy.

BACKGROUND: Robotic sleeve gastrectomy has been increasing in annual incidence in recent years. Although rare, post op bleeding and leak in these cases can lead to significant morbidity, mortality, and healthcare utilization. OBJECTIVES: To determine preop comorbidity risk factors and operative techniques associated with risk of bleeding or leak within 30 days of robotic sleeve gastrectomy. METHODS: The MBSAQIP database was analyzed. A total of 53,548 RSG cases were included in analysis. Surgeries took place from accredited centers in the USA from 2015 to 2019. CONCLUSIONS: Preoperative anticoagulation, renal failure, COPD, and OSA were found to increase in the risk for transfusion requirements after SG. Receiving a transfusion and smoking increased the risk for leak. Staple line reinforcement significantly decreased transfusion and leak rates. Staple line oversewing did not have an impact on bleeding or leak.

Literature review on antiobesity medication use for metabolic and bariatric surgery patients from the American Society for Metabolic and Bariatric Surgery Clinical Issues Committee.

The following literature search is in response to inquiries made to the American Society for Metabolic and Bariatric Surgery (ASMBS) regarding antiobesity medication (AOM) use in patients who are having or have already had metabolic and bariatric surgery (MBS). These recommendations are based on current clinical knowledge, expert opinion, and published peer-reviewed scientific evidence available at this time. This paper is not intended to establish a local, regional, or national standard of care. The paper will be revised in the future as additional evidence becomes available.

Telemedicine in Primary Care During the COVID-19 Pandemic: Provider and Patient Satisfaction Examined.

Introduction: During the COVID-19 pandemic telemedicine was rapidly expanded and incorporated into day-to-day practice by primary care providers to allow continued access to care for patients during this time. The quick adoption of telemedicine occurred out of necessity for social distancing, and evidence-based approaches are needed to determine the future utility of this approach to delivering care. The objective of this study was to identify factors associated with both provider and patient satisfaction with telemedicine visits in a primary care setting during the COVID-19 pandemic. Materials and Methods: This survey-based study was conducted in 2020. Surveys were distributed electronically by e-mail to providers and patients. Participants: Surveys related to satisfaction levels with telemedicine were distributed to 73 primary care providers and 6,626 patients. Main Outcomes and Measures: The primary measures of this study were satisfaction level with telemedicine in primary care. Results: Studies were completed by 23 primary care providers and 1,692 patients. Most patient participants were female (70.8%), white (89.7%), non-Hispanic or non-Latino (96.6%), and Massachusetts residents (96.9%). Variables that were found to be significantly associated with higher levels of satisfaction with telemedicine visits included: travel time saved >30 min (odds ratio [OR] 1.8), having an easy visit connection (OR = 3.2), use of Zoom© video visit over telephone only (OR = 2.8), and identifying as female (OR 1.8). Conclusions and Relevance: Patients and providers reported high levels of satisfaction with telemedicine visits in a primary care setting. Providers felt that telemedicine visits usually take the same amount or less time than in-person visits. Both providers and patients reported a desire to see telemedicine visits continued after the pandemic. Patients who saved more than 30 min of travel time found it easy to connect or those who were female were more likely to be satisfied with telemedicine visits, while those that had telephone visits were less likely to be satisfied than those that had Zoom© visits.

Bariatric Surgery is Safe for Patients After Recovery from COVID-19.

BACKGROUND: Studies of patients who have undergone surgery while infected with COVID-19 have shown increased risks for adverse outcomes in both pulmonary complications and mortality. It has become clear that the risk of complications from perioperative COVID-19 infection must be weighed against the risk from delayed surgical treatment. Studies have also shown that prior bariatric surgery conveys protection against mortality from COVID-19 and that obesity is the biggest risk factor for mortality from COVID-19 infection in adults under 45 years of age. Studies in patients who have fully recovered from COVID-19 and underwent elective surgery have not become widely available yet. OBJECTIVES: This multi-institutional case series is presented to highlight patients who developed COVID-19, fully recovered, and subsequently underwent elective bariatric surgery with 30-day outcomes available. SETTING: Nine bariatric surgery centers located across the United States. METHODS: This multicenter case series is a retrospective chart review of patients who developed COVID-19, recovered, and subsequently underwent bariatric surgery. Fifty-three patients are included, and 30-day morbidity and mortality were analyzed. RESULTS: Thirty-day complications included esophageal spasm, dehydration, and ileus. There were no cardiovascular, venous thromboembolism (VTE) or respiratory events reported. There were no 30- day mortalities. CONCLUSIONS: Bariatric surgery has been safely performed in patients who made a full recovery from COVID-19 without increased complications due to cardiovascular, pulmonary, venous thromboembolism, or increased mortality rates.

Supercharging of delayed pedicled transverse rectus abdominis myocutaneous flaps, is it a viable option?

INTRODUCTION: Arterial and venous insufficiency may become evident even in delayed pedicled TRAM flaps. This study assesses the possibility of using the previously ligated deep inferior epigastric vessels for microvascular supercharging during reconstruction. METHODS: Twenty-two patients underwent delay by ligation of the inferior epigastric vessels prior to TRAM flap breast reconstruction. The deep inferior epigastric vessels were excised at the time of reconstruction 10-14 days after delay and microscopically examined for vascular compromise that might prevent use in microvascular anastomosis at the time of reconstruction. RESULTS: 20/22 (91%) of the deep inferior epigastric vessels (20 arteries and accompanying veins) showed clot immediately adjacent to the ligature only and 2/22 (9%) showed clot extending only 5-10 mm. None of these vessels (0%) showed clot in the distal 2 cm of their length (adjacent to the flap). Evidence of intramural hematoma, delamination, and endothelial abnormalities were not found in any of the vessels. An additional patient who was a 48-year-old female underwent bilateral pedicled TRAM flap breast reconstruction and one of the flaps exhibited inadequate capillary refill intraoperatively after transfer to the mastectomy defect. Supercharging of the flap utilizing the previously ligated inferior epigastric artery improved capillary refill and the flap survived completely postoperatively. CONCLUSION: Our findings demonstrate patency of the inferior epigastric vessels after ligation for TRAM delay during the time frame usually used for delay to take effect.
