Peroral endoscopic myotomy: 10-year outcomes from a large, single-center U.S. series with high follow-up completion and comprehensive analysis of long-term efficacy, safety, objective GERD, and endoscopic functional luminal assessment.

BACKGROUND AND AIMS: Peroral endoscopic myotomy (POEM) is becoming the treatment of choice for achalasia. Data beyond 3 years are emerging but are limited. We herein report our 10-year experience, focusing on long-term efficacy and safety including the prevalence, management, and sequelae of postoperative reflux. METHODS: This was a single-center prospective cohort study. RESULTS: Six hundred ten consecutive patients received POEM from October 2009 to October 2019, 160 for type 1 achalasia (26.2%), 307 for type II (50.3%), 93 for type III (15.6%), 25 for untyped achalasia (4.1%), and 23 for nonachalasia disorders (3.8%). Two hundred ninety-two patients (47.9%) had prior treatment(s). There was no aborted POEM. Median operation time was 54 minutes. Accidental mucosotomies occurred in 64 patients (10.5%) and clinically significant adverse events in 21 patients (3.4%). No adverse events led to death, surgery, interventional radiology interventions/drains, or altered functional status. At a median follow-up of 30 months, 29 failures occurred, defined as postoperative Eckardt score >3 or need for additional treatment. The Kaplan-Meier clinical success estimates at years 1, 2, 3, 4, 5, 6, and 7 were 98%, 96%, 96%, 94%, 92%, 91%, and 91%, respectively. These are highly accurate estimates because only 13 patients (2%) were missing follow-up assessments. One hundred twenty-five patients (20.5%) had reflux symptoms more than once per week. At a median of 4 months, the pH study was completed in 406 patients (66.6%) and was positive in 232 (57.1%), and endoscopy was completed in 438 patients (71.8%) and showed reflux esophagitis in 218 (49.8%), mostly mild. CONCLUSIONS: POEM is exceptionally safe and highly effective on long-term follow-up, with >90% clinical success at ≥5 years.

Cardiac tamponade in COVID-19 patients: Management and outcomes.

IMPORTANCE: Cardiac tamponade requiring emergent intervention is a possible complication of coronavirus disease 2019 (COVID-19) infection. Favorable clinical outcomes are possible if timely management and drainage are performed unless ventricular failure develops. OBSERVATION: Cardiac tamponade in COVID-19, based on the limited reported cases, seems to be more common among middle-aged men with observed complications in black and ethnic minorities. Prognosis is worse amongst patients with concomitant ventricular failure. DESIGN AND METHODS: This is a case series of three COVID-19 patients complicated by cardiac tamponade, requiring surgical intervention at a single institution in New York. INTERVENTION: Pericardial window, Pericardiocentesis. OUTCOME: One patient had recurrence of cardiac tamponade with hemorrhagic component but fully recovered and was discharged home. Two patients developed cardiac tamponade with concomitant biventricular failure, resulting in death. CONCLUSION AND RELEVANCE: Cardiac tamponade with possible concomitant biventricular failure can develop in COVID-19 patients; incidence seems to be highest at the point of marked inflammatory response. Concomitant ventricular failure seems to be a predictor of poor prognosis.

Spiral enteroscopy-assisted ERCP in bariatric-length Roux-en-Y anatomy: a large single-center series and review of the literature (with video).

BACKGROUND: Deep enteroscopy-assisted ERCP (DEA-ERCP) in post-bariatric Roux-en-Y (RY) anatomy is challenging. Laparoscopy-assisted ERCP (LA-ERCP) and EUS-directed transgastric ERCP (EDGE) are technically easier and faster but are more invasive and morbid procedures. Therefore, we have used DEA-ERCP as our first-line approach, reserving EDGE and LA-ERCP for cases in which adjunctive techniques that cannot be performed through an enteroscope are required (eg, EUS-FNA, sleeve sphincter of Oddi manometry), or DEA-ERCP failures. The 2 main methods for DEA-ERCP are balloon- and spirus-assisted. Current literature on spiral enteroscopy ERCP (SE-ERCP) in bariatric RY anatomy is scant with low success rates reported. Our center has nearly exclusively used SE-ERCP for bariatric patients. Here, we report one of the largest such series to date. METHODS: This is a retrospective cohort study of consecutive patients with bariatric-length RY anatomy who had SE-ERCP from December 2009 to October 2016 at a tertiary care center, by one operator (S.N.S.). Primary outcomes included success at reaching the papilla, cannulation success, success of desired therapeutic intervention, and overall SE-ERCP success. RESULTS: Thirty-five SE-ERCPs were performed (28 in bariatric RY gastric bypass and 7 other long-limb RY surgical reconstructions). The papilla was reached in 86% (30/35) of cases. Cannulation success in patients in whom deep cannulation was indicated (28/30) was 100% (28/28 cases, including the 24 cases with native papilla). Therapeutic ERCP success was 100% (28/28). Overall SE-ERCP success was 86% (30/35). Median length of stay was 3 days. Median procedure time was 189 minutes. Reasons for SE-ERCP failures included RY anastomosis stricture, adhesions (2), long Roux limb, and redundant small bowel. Two of these patients underwent interventional radiology-guided percutaneous biliary drainage, 2 patients had laparoscopy-assisted ERCP, and 1 patient had EUS-guided antegrade cholangioscopy with sphincteroplasty and stone clearance. There were no adverse events. CONCLUSION: With sufficient allotted time (median procedure time ∼3 hours) and high operator experience (a single-operator volume that exceeds that of other published series), SE-ERCP is safe and effective in bariatric, long-limb RY patients with an overall success rate of 86%, which is higher than previously reported.

Per-oral endoscopic myotomy in patients with or without prior Heller's myotomy: comparing long-term outcomes in a large U.S. single-center cohort (with videos).

BACKGROUND AND AIMS: Heller's myotomy (HM) is one of the most effective treatments for esophageal achalasia. However, failures do exist, and the success rate tends to decrease with time. The efficacy of rescue treatments for patients with failed HM is limited. A few small-scale studies have reported outcomes of per-oral endoscopic myotomy (POEM) in these patients. We conducted this study to systematically assess feasibility, safety, and efficacy of POEM on patients who have had HM. METHODS: Patients at least 3 months out from POEM were selected from our prospective database: 318 consecutive POEMs performed from October 2009 to October 2016. The efficacy and safety of POEM were compared between the 46 patients with prior HM and the remaining 272 patients. RESULTS: Patients with prior HM had longer disease history, more advanced disease, more type I and less type II achalasia, lower before-POEM Eckardt scores, and lower before-POEM lower esophageal sphincter (LES) pressure (all P < .01). Procedure parameters and follow-up results (clinical success rate, Eckardt score, LES pressure, GERD score, esophagitis, and pH testing) showed no significant difference between the 2 groups. For the 46 HM-POEM patients, no clinically significant perioperative adverse events occurred. Their overall clinical success rate (Eckardt score ≤3 and no other treatment needed) was 95.7% at a median follow-up of 28 months. CONCLUSION: POEM as a rescue treatment for patients with achalasia who failed HM is feasible, safe, and highly effective. It should be the treatment of choice in managing these challenging cases at centers with a high level of experience with POEM.

Evaluation of Hydrocortisone Continuous Infusion Versus Intermittent Boluses in Resolution of Septic Shock.

PURPOSE: To compare the effectiveness of continuous infusion of hydrocortisone versus intermittent boluses in the resolution of septic shock. METHODS: A retrospective chart review was performed to investigate the effects of low-dose hydrocortisone continuous infusion (200 mg per day) versus intermittent boluses (50 mg every six hours) in septic shock patients who did not respond to fluid resuscitation and vasopressors. The primary outcome was time to resolution of shock, defined by time from the initiation of hydrocortisone to time of vasopressor withdrawal when mean arterial pressure was greater than 65 mm Hg. Hospital length of stay, intensive care unit (ICU) length of stay, 28-day all-cause in-hospital mortality, and hyperglycemia were secondary outcomes. RESULTS: Of the 51 patients in the study, 33 received intermittent boluses of hydrocortisone. The median time to resolution of shock in the continuous group was three days, compared with a mean time of two days in the bolus group (P = 0.41). Mean hospital length of stay was 18.7 ± 19.4 days in the continuous group versus 18.6 ± 17.4 days in the bolus group (P = 0.77). Mean ICU length of stay was 10.4 ± 12.5 days in the continuous group versus 11.1 ± 9.2 days in the bolus group (P = 0.31). Thirteen patients (72%) in the continuous group died within 28 days, compared with 20 (60%) in the bolus group (P = 0.76). Five patients (28%) had hyperglycemic episodes after being given hydrocortisone in the continuous infusion group, compared with 20 patients (60%) in the bolus group (P = 0.04). CONCLUSION: There was no significant difference in time to resolution of septic shock between continuous infusion (200 mg per day) and intermittent boluses (50 mg every six hours) of hydrocortisone. There were also no statistically significant differences in overall hospital length of stay, ICU length of stay, and 28-day all-cause in-hospital mortality. However, there was a significant difference in the incidence of hyperglycemia between the two groups, with patients in the bolus group experiencing more hyperglycemia than those in the continuous infusion group.

Evolution of the treatment of splenic injuries: from surgery to non-operative management. / Evolución en el tratamiento conservador del traumatismo esplénico contuso.

The spleen is one of the most frequently injured organs in blunt abdominal trauma. In the past decades, the treatment of patients with blunt splenic injury has shifted from operative to non-operative management. The knowledge of physiology and immunology of the spleen have been the main reasons to develop techniques for splenic salvage. The advances in high-resolution imaging techniques, as well as less invasive procedures, including angiography and angioembolization, have allowed a higher rate of success in the non-operative management. Non-operative management has showed a decrease in overall mortality and morbidity. The aim of this article is to analyze the current management of splenic injury based on a literature review of the last 30 years, from we have identified 63,205 patients. This would enable the surgeons to provide the best care possible in every case.

Prevalence of Delirium and Coma In Mechanically Ventilated Patients Sedated With Dexmedetomidine or Propofol.

OBJECTIVE: To assess the prevalence of delirium and coma in mechanically ventilated patients sedated with dexmedetomidine or propofol alone; to evaluate the hospital length of stay for both treatment groups; and to evaluate the level of sedation, adverse effects, and hospital outcomes. METHODS: Medical records were reviewed retrospectively for patients who were admitted to the medical or surgical intensive care units (ICUs) in a 591-bed teaching hospital and who received either dexmedetomidine or propofol alone for 24 hours or more for sedation. RESULTS: A total of 111 patients were included in the study, with 56 patients in the dexmedetomidine group and 55 patients in the propofol group. Results of the analysis showed that the propofol group had a higher prevalence of coma (43.6% versus 12.5%; P < 0.001). Dexmedetomidine patients had a longer median hospital length of stay of 23.5 days (interquartile range [IQR], 11.5-39.5 days) versus 15.0 days (IQR, 7.0-24.0 days; P = 0.01). The rates of delirium were similar in both groups, with 16% in dexmedetomidine-treated patients versus 20% in propofol-treated patients (P = 0.63). CONCLUSION: No difference in the prevalence of delirium was found when comparing the dexmedetomidine- and propofol-treated groups. Propofol was associated with more coma and oversedation; dexmedetomidine was associated with longer time to extubation, longer length of stay in the ICU, and longer hospital length of stay.

The light at the end of the tunnel: a single-operator learning curve analysis for per oral endoscopic myotomy.

BACKGROUND: Per oral endoscopic myotomy (POEM) represents a natural orifice transluminal endoscopic surgery approach to Heller myotomy. Our center was the first to offer POEM outside of Japan, allowing us to accumulate what is likely the highest single-operator POEM volume in the United States. OBJECTIVE: To define the POEM learning curve of a gastroenterologist by using a larger data set and more detailed statistical analysis than used in 2 other reports of POEM performed by surgeons. DESIGN: Prospective cohort study. SETTING: Tertiary-care academic medical center. PATIENTS: We analyzed the first 93 consecutive POEMs on patients with achalasia aged >18 years without contraindications to POEM performed by a single operator from October 2009 to November 2013. INTERVENTIONS: (1) Efficiency estimation via cumulative sum (CUSUM) analysis, (2) mastery estimation via penalized basis-spline regression and CUSUM analysis, (3) correlation of operator experience with clinical outcomes (Eckardt score improvement, lower esophageal sphincter pressure reduction) and technical errors (accidental mucosotomy rate), and (4) unadjusted and adjusted regression analysis to assess how patient characteristics affected procedure time by using a generalized linear model. MAIN OUTCOME MEASUREMENTS: Clinical outcomes, procedure time, technical errors. RESULTS: Efficiency was attained after 40 POEMs and mastery after 60 POEMs. When we used the adjusted regression analysis, only case number (operator experience) significantly affected procedure time (P < .0001). Improvements in clinical outcomes were excellent but not significantly affected by operator experience, as was the case with accidental mucosotomies. Procedure time was not significantly affected by age, sex, achalasia stage, baseline lower esophageal sphincter pressure, baseline Eckardt score, prior treatment of achalasia, prior botulinum toxin injection, incidence of accidental mucosotomies, length of myotomy, or type of knife used (all P > .05). LIMITATIONS: Our analysis may underestimate the number of POEMs required to achieve mastery for operators with limited or no endoscopic submucosal dissection experience. CONCLUSION: These results offer thresholds for efficiency and mastery of a single gastroenterologist operator that may guide the efforts of novice POEM operators.

Effect of Intravenous Acetaminophen on Postoperative Opioid Use in Bariatric Surgery Patients.

BACKGROUND: The use of opioids to achieve adequate pain relief following surgery is a common clinical practice. Opioids, however, are associated with serious adverse effects, such as respiratory depression, excessive sedation, and prolonged ileus, as well as increased mortality. The administration of intravenous (IV) acetaminophen to control postoperative pain has been effective in reducing opioid consumption in various surgical populations, but no studies have been conducted in bariatric surgery patients. This investigation was performed to determine whether IV acetaminophen reduces opioid requirements after bariatric surgery. METHODS: IV acetaminophen was added to the Winthrop-University Hospital formulary in September 2012. We conducted a retrospective chart-review analysis of bariatric surgery patients who received at least four doses of IV acetaminophen (1 g every six hours) plus opioids from October 2012 to March 2013 (after IV acetaminophen was added to the hospital formulary), compared with bariatric surgery patients who received only opioids for postoperative pain control from January 2012 to June 2012 (before IV acetaminophen was added to the hospital formulary). The study's primary endpoint was the difference between the two groups in opioid consumption, expressed in oral morphine equivalents (OMEs). Secondary endpoints included the reduction in the baseline pain score; the total amount of each opioid used; and the average hospital length of stay (LOS). RESULTS: A total of 96 patients were identified for potential enrollment from January 2012 to March 2013. Eight patients, however, did not qualify for participation because they had received only one dose of IV acetaminophen. The remaining 88 patients comprised two study groups: IV acetaminophen plus opiates (n = 44) and IV opiates alone (n = 44). Paradoxically, the patients in the acetaminophen/opiates group required significantly more opiates (in OMEs) compared with the group that received opiates alone (median, 93.5 mg versus 63.0 mg, respectively; P = 0.017). There were no significant differences between the two treatment groups in terms of the median change from baseline in pain scores (-4 versus -4; P = 0.162) or the median hospital LOS (two days versus two days; P = 0.704). CONCLUSION: IV acetaminophen did not reduce opioid use for postoperative pain management in bariatric surgery patients.

The Effect of Diet Composition on the Post-operative Outcomes of Roux-en-Y Gastric Bypass in Mice.

PURPOSE: Roux-en-Y gastric bypass (RYGB) leads to the improvement of many obesity-associated conditions. The degree to which post-operative macronutrient composition contributes to metabolic improvement after RYGB is understudied. METHODS: A mouse model of RYGB was used to examine the effects of diet on the post-operative outcomes of RYGB. Obese mice underwent either Sham or RYGB surgery and were administered either chow or HFD and then monitored for an additional 8 weeks. RESULTS: After RYGB, reductions to body weight, fat mass, and lean mass were similar regardless of diet. RYGB and HFD were independently detrimental to bone mineral density and plasma vitamin D levels. Independent of surgery, HFD accelerated hematopoietic stem and progenitor cell proliferation and differentiation and exhibited greater myeloid lineage commitment. Independent of diet, systemic iron deficiency was present after RYGB. In both Sham and RYGB groups, HFD increased energy expenditure. RYGB increased fecal energy loss, and HFD after RYGB increased fecal lipid content. RYGB lowered fasting glucose and liver glycogen levels but HFD had an opposing effect. Indices of insulin sensitivity improved independent of diet. HFD impaired improvements to dyslipidemia, NAFLD, and fibrosis. CONCLUSION: Post-operative diet plays a significant role in determining the degree to which RYGB reverses obesity-induced metabolic abnormalities such as hyperglycemia, dyslipidemia, and NAFLD. Diet composition may be targeted in order to assist in the treatment of post-RYGB bone mineral density loss and vitamin D deficiency as well as to reverse myeloid lineage commitment. HFD after RYGB continues to pose a significant multidimensional health risk.

Predictors of Length of Hospital Stay After Reduction of Internal Hernia in Patients With a History of Roux-en-Y Gastric Bypass.

BACKGROUND: Postoperative internal hernias after Roux-en-Y gastric bypass (RYGB) have an incidence of 2%-9% and are a surgical emergency. Evidence on factors associated with length of stay (LOS) after emergent internal hernia reduction in RYGB patients is limited. METHODS: This is a retrospective review of patients who underwent internal hernia reduction after RYGB at our tertiary care center over a 5 year period from 2015 to 2020. Demographics, comorbidities, and intra- and postoperative hospital course were collected. Univariate and multivariate linear regressions were used to investigate factors associated with LOS. RESULTS: We identified 38 patients with internal hernia after RYGB. These patients with mean age 44.1 years were majority female (71.1%) and white race (60.5%). Of the 24 patients where the RYGB was done at our institution, the mean RYGB to IH interval was 43 months. Petersen's defect (57.8%) followed by jejuno-jejunal mesenteric defect (31.6%) were the most common locations for IH. Both Petersen's and jejuno-jejunal mesenteric hernias were found in 4 cases (10.5%). Revision of bypass and small bowel resection were required in 13.2% and 5.3% of cases, respectively. The median (interquartile range) length of stay (LOS) was 2 days. On the multivariate analysis, male sex (P = .019), conversion to exploratory laparotomy (P = .005), and resection of small bowel (P < .001) were independent risk factors for increased LOS. CONCLUSION: The most common location of IH after RYGB is Petersen's defect, followed by jejuno-jejunal mesenteric defect. LOS was significantly associated with male sex, exploratory laparotomy, and resection of small bowel.

Kwashiorkor after gastric bypass.

Gastric bypass has grown in popularity in recent years due to its high efficacy in achieving long-term weight loss in patients with morbid obesity. Gastric bypass has been described to further exacerbate baseline nutritional deficiencies due to reduced gastric capacity and malabsorption. In rare cases, when protein deficiency is severe, Kwashiorkor disease may arise. The incidence of Kwashiorkor specifically following gastric bypass is rare, with an incidence of 4.7%. We report a case of a female patient who underwent a gastric bypass and subsequently developed Kwashiorkor. Physicians' suspicion of index for Kwashiorkor should be high for patients presenting with signs or symptoms of severe malnutrition following weight-loss procedures.

Incidental aortocaval fistula in the setting of an unruptured abdominal aortic aneurysm.

An aortocaval fistula, a rare abnormal vascular communication between the aorta and inferior vena cava, is most commonly associated with abdominal aortic aneurysms (AAAs). Other factors leading to aortocaval fistula formation include atherosclerosis, collagen vascular diseases, vasculitis, hematogenous infections, prior spinal surgery, malignancy and radiation exposure. In rare instances, aortocaval fistulas may be discovered incidentally on abdominal imaging. We report an unusual case of an incidental aortocaval fistula in a 93-year-old male patient with an unruptured AAA, presenting with shortness of breath, malaise and lethargy. The patient had no other obvious risk factors for aortocaval fistula formation. Multidetector computed tomography angiography helped identify the fistula, and the patient was eventually transferred to hospice for comfort measures. This case highlights the importance of detailed imaging and preoperative planning in managing aortocaval fistulas and associated AAAs.

Stop the Bleed: A Prospective Evaluation and Comparison of Tourniquet Application in Security Personnel Versus Civilian Population.

INTRODUCTION: Stop the Bleed (STB) is a national training program aiming to decrease the mortality associated with life-threatening bleeding due to injury. The purpose of this study was to evaluate the efficacy and confidence level of security personnel placing a tourniquet (TQ) compared to civilians. METHODS: Pre and post questionnaires were shared with security personnel (Group 1) and civilians (Group 2). Both groups were assessed to determine comfort level with TQ placement. Time and success rate for placement was recorded pre- and post-STB training. A generalized linear mixed model or generalized estimating equations was used to compare pre and post measurements. RESULTS: There were 234 subjects enrolled. There was a statistically significant improvement between the pre- and post-training responses in both groups with respect to comfort level in placing a TQ. Participants also demonstrated increased familiarity with the anatomy and bleeding control after STB training. A higher successful TQ placement was obtained in both groups after STB training (Pre-training: Group 1 [17.4%], Group 2 [12.8%]; Post-training: Group 1 [94.8%], Group 2 [92.3%]). Both groups demonstrated improved time to TA placement with a longer mean time improvement achieved in Group 1. Although the time to TQ placement pre-and post-training was statistically significant, we found that the post-training times between Groups 1 and 2 were similar (P = .983). CONCLUSIONS: Participants improved their confidence level with the use of hemorrhage control techniques and dramatically increased the rate and time to successful placement of a TQ. While civilians had the greatest increase in comfort level, the security personnel group saw the most significant reduction in the time to successful TQ placement. These findings highlight the critical role of STB in educating and empowering both civilians and security personnel in bleeding control techniques.

Outcomes in Obese vs Non-Obese Injured Patients at a Level 1 Trauma Center and Bariatric Surgery Center of Excellence.

BACKGROUND: We hypothesized that the outcomes of trauma patients with a body mass index (BMI) equal to or greater than 30 compared to patients with BMI less than 30 would not differ at a level 1 trauma center that is also a Metabolic and Bariatric Surgery Center of Excellence in the Metabolic and Bariatric Surgery Accreditation Quality Improvement Program (MBSAQIP). STUDY DESIGN: Patients equal to and greater than 18 years old treated between 1/1/2018 and 12/31/2020 were included. Demographics, BMI, comorbidities, and outcomes (hospital-LOS, ICU-LOS, blood products used, and mortality) were compared between 2 groups: obese (BMI ≥30) vs non-obese (BMI <30). RESULTS: Of the 4192 patients identified, 3821 met the inclusion criteria; 3019 patients had a BMI <30, and 802 had a BMI ≥30. There was a statistically significant difference between the 2 groups with respect to gender (females: 57% vs 47%, P < .0001) and age (median: 80 [IQR: 63-88] vs 69 [IQR: 55-81], P < .0001). When adjusted for age, sex, DM, dementia, ISS, and ICU admission, there was no statistically significant difference in hospital-LOS (4.30 [95% CI: 4.10, 4.52] vs 4.48 [95% CI: 4.18, 4.79]) or mortality. No statistical differences were seen between the 2 groups in blood product use. CONCLUSIONS: Obesity did not correlate with poorer outcomes at an ACS-verified level 1 Trauma Center and Bariatric Surgery Center of Excellence. Further studies are needed to determine whether outcomes vary at hospitals without both designations.

Surgical considerations in the resection of solitary fibrous tumors of the pleura.

Solitary fibrous tumors (SFTs) are rare mesenchymal pleural neoplasms with an overall good prognosis and low recurrence rate if completely resected and if degree of differentiation is favorable. Within the last decade, advances in research have led to more reliable methods of differentiating SFTs from other soft tissue tumors. Historically, several markers were used to distinguish SFTs from similar tumors, but these markers had poor specificity. Recent evidence showed NAB2-STAT6 fusion gene to be a distinct feature of SFTs with 100% specificity and sensitivity. Surgical resection, with an emphasis on obtaining negative margins, is the mainstay of treatment for SFTs. Preoperative planning with detailed imaging is imperative to delineate the extent of disease and vascular supply. One important radiologic distinction to aid delineation of a pleural-based tumor compared to a pulmonary parenchymal-based tumor is the angle that the tumor forms with the chest wall, which is obtuse for a pleural-based tumor, and acute for tumors of the lung parenchyma. Often, preoperative tissue diagnosis is not available, and surgery is both diagnostic and curative. Intraoperatively, emphasis should be on complete resection with negative margins. SFTs are resected via several approaches: thoracotomy, sternotomy with the option of hemi-clamshell extension, video-assisted thoracoscopic surgery, and robotic approach, which is increasingly being used and is our preference. We recommend a minimally invasive approach for most lesions, and have resected SFTs of the pleura that are up to 12 cm with the robotic approach. However, the current literature often cites 5 cm as the cut off for an open thoracotomy. Nevertheless, even with larger tumors, a minimally invasive robotic approach is our preference and practice. For giant SFTs (> 20 cm), an open approach may be preferable. Multiple thoracotomies and rib resection may be required to gain adequate exposure and ensure complete resection in these tumors. However, it is noteworthy that most of these tumors have a soft consistency and thus, once bagged, can easily be removed minimally invasively, and thus minimally invasive approach should not be completely ruled out. Recurrence in SFTs usually results from incomplete resection and redo surgery may portend a favorable prognosis.

Impact of Enhanced Recovery After Surgery (ERAS) Combined with Bariatric Surgery Targeting Opioid Prescriptions (BSTOP) Protocol on Patient Outcomes, Length of Stay and Opioid Prescription After Bariatric Surgery.

BACKGROUND: Evidence shows that 14.2% of opioid-naive patients have long-term opioid dependence after bariatric surgery. Enhanced recovery after surgery (ERAS) protocols are widely used in bariatric surgery, while bariatric surgery targeting opioid prescriptions (BSTOP) protocols were recently introduced. We will investigate the combined impact of ERAS and BSTOP protocols after bariatric surgery. METHODS: We conducted a retrospective review for patients who underwent either a sleeve gastrectomy or Roux-en-Y gastric bypass at a tertiary care center. Pre-intervention and post-intervention data were compared. Primary outcomes were length of stay (LOS), 30-day readmission, 30-day complications, and discharge on opioids. Multivariate Poisson regression with robust standard error was used to analyze LOS. RESULTS: There was no significant difference in 30-day emergency room visits (3.3% vs. 4.0%; p value = 0.631), 30-day readmission (4.4% vs. 5.4%; p value = 0.577) or 30-day complication rate (4.2% vs. 6.4%; p value = 0.199). LOS was significantly lower in the post-intervention group; mean (interquartile range) 2 (1-2) days vs. 1 (1-2) day, p value < 0.001. On multivariate analysis, the post-intervention group had 0.74 (95% confidence interval 0.65-0.85; p value < 0.001) times lower LOS as compared to pre-intervention group. Patients with DM had a significantly longer LOS (relative risk: 1.22; p = 0.018). No other covariates were associated with LOS (p value < 0.05 for all). BSTOP analysis found a significant difference between the two groups. Discharge on opioids decreased from 40.6% pre-intervention to 7.1% post-intervention. CONCLUSION: ERAS and BSTOP protocols reduced length of stay and opioid need at discharge without an increase in complication or readmission rates.

The First COVID-19 Pandemic Wave and the Effect on Health Care Trainees: A National Survey Study.

BACKGROUND: This study observes the trends and patterns among trainees during the coronavirus disease 2019 (COVID-19) pandemic and their response to resident education and hospital/program support. METHODS: An anonymous online 31-question survey was distributed to medical students and postgraduate year residents. Topics included were demographics, clinical responsibilities, educational/curricula changes, and trainee wellness. Descriptive analysis was performed for each set of demographic groupings as well as 2 and 3 group comparisons. RESULTS: Total 1051 surveys collected, 930 used for analysis: 373 (40.1%) male, 434 (46.6%) aged 30-34 years, 588 (63.2%) white, 417 (44.8%) married, 168 (18%) with children, and 323 (34.7%) from the Northeast region. The Northeast experienced difficulty sleeping, feelings of guilt, hopelessness, and changes in appetite (P = .0077). The pandemic interfered significantly with relationships and living situations (P < .0001). Trainees 18-34 years believed the pandemic affected residency training (P < .0001). Surgical residents were concerned about reaching numbers of operative procedures to graduate (P < .0001). Residency programs adhered to ACGME work restrictions (P < .0001). CONCLUSION: We aim to provide continued educational support for our trainees' clinical development and well-being during the COVID-19 pandemic.

Safety of Bariatric Surgery in Patients With Congestive Heart Failure: Results of an 11-Year Retrospective Study.

INTRODUCTION: Congestive heart failure (CHF) is a known risk factor for increased postoperative morbidity. However, the safety in patients with CHF has not been well established. The objective of this study was to assess the safety of surgery in patients with a history of CHF undergoing bariatric surgical procedures. METHODS: Retrospective review of a prospectively maintained Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) Center of Excellence database. Patients with known CHF undergoing bariatric procedures over an 11-year period were reviewed. RESULTS: Over the 11-year period, 4470 total bariatric surgeries were performed, of which 41 (.92%) patients had known CHF. Twenty-one patients were men (51.2%) with a mean age of 55.8 years and mean body mass index (BMI) of 51.9. Comorbidities included hypertension (87.8%), obstructive sleep apnea (80.5%), osteoarthritis (63.4%), gastroesophageal reflux disease (56%), and diabetes (53.7%). Surgical procedures included 16 sleeve gastrectomies (SGs) (39%), 11 Roux-en-Y gastric bypasses (RYGBs) (26.8%), 10 laparoscopic adjustable gastric bands (LAGBs) (24.4%), 1 removal of a gastric band and conversion to SG (2.4%), 1 removal of a gastric band to RYGB (2.4%), 1 gastric band over RYGB pouch (2.4%), and 1 gastric band replacement (2.4%). All cases were performed minimally invasively (73.2% laparoscopic and 26.8% robotic). Mean LOS was 2.53 days. Thirty-day complications included 2 readmissions (4.9% [1 small bowel obstruction and 1 pulmonary edema]), 1 reoperation (2.4% [small bowel obstruction]), and 1 mortality (2.4%) on postoperative day 30 unrelated to the surgery. CONCLUSIONS: Bariatric surgery can be performed safely in patients with CHF.

Improved Morbidity, Mortality, and Cost with Minimally Invasive Colon Resection Compared to Open Surgery.

Background and Objectives: Despite the growth of minimally invasive surgery (MIS) in many specialties, open colon surgery is still routinely performed. The purpose of this study was to compare outcomes and costs between open colon and minimally invasive colon resections. Methods: We analyzed outcomes between January 1, 2016 and December31, 2018 using the Vizient® clinical database. Demographics, hospital length of stay, readmissions, complications, mortality, and costs were compared between patients undergoing elective open and minimally invasive colon resections. For bivariate analysis, Wilcoxon rank-sum test was used for continuous variables and χ2 test was used for categorical variables. Multiple Logistic and Quintile regression were used for multivariable analyses. Results: A total of 88,405 elective colon resections (open: 56,599; minimally invasive: 31,806) were reviewed. A significantly larger proportion of patients undergoing minimally invasive surgery were obese (body mass index > 30) compared to those undergoing open surgery (71.4% vs. 59.6%; p < 0.0001). As compared to minimally invasive colectomy, open colectomy patients had: a longer median length of stay [median (range): 7 (4-13) days vs. 4 (3 - 6) days, p < 0.0001], higher 30-day readmission rate [n = 8557 (15.1%) vs. 2815 (8.9%), p < 0.0001], higher mortality [n = 2590 (4.4%) vs. 107 (0.34%), p < 0.0001], and a higher total direct cost [median (range): $13,582 (9041-23,094) vs. $9013 (6748 - 12,649), p < 0.0001]. Multivariable models confirmed these findings. Conclusion: Minimally invasive colon surgery has clear benefits in terms of length of stay, readmission rate, mortality and cost, and the routine use of open colon resection should be revaluated.
