Laparoscopic Cholecystectomy in Cardiogenic Shock And Heart Failure.

Background: Patients with cardiogenic shock (CS) or heart failure can develop ischemic cholecystitis from a systemic low-flow state. Cholecystectomy in high-risk patients is controversial. Percutaneous cholecystostomy tube (PCT) is often the chosen intervention; however, data on PCT as definitive treatment are conflicting. Data on cholecystectomy in these patients are limited. This study discusses outcomes following laparoscopic cholecystectomy (LC) in this patient population. Methods: This is a retrospective review of patients who underwent LC from 2015 to 2019 while hospitalized for CS or heart failure. Surgical services are provided by fellowship-trained minimally invasive surgeons at a single, academic, tertiary-care center. Patient characteristics are reported as frequencies' percentages for categorical variables. Odds ratio is used to determine the association between comorbidities and complications. Results: Twenty-four patients underwent LC. Around 83% were white and 79% were male. Many were anticoagulated (88%), with Class IV heart failure (63%), and required vasopressors (46%) at the time of surgery. Fourteen of 24 (58%) had at least one circulatory device at the time of surgery: extracorporeal membrane oxygenation, left ventricular assist device, Impella, tandem heart, and total artificial heart. Four patients (17%) had PCT preoperatively. Fifteen days were the average interval between diagnosis and surgery. Pneumoperitoneum was tolerated by all, and 0% converted to open. Most common complication was bleeding (52%). Nine patients (37.5%) underwent 21 reoperations, one of which (4%) was related to cholecystectomy. Mortality occurred in 5 patients (20.8%); interval between cholecystectomy and mortality ranged 6-30 days. Conclusion: Although high risk, LC is a treatment option in patients with ischemic cholecystitis at risk for death from sepsis.

The SAGES masters program presents the 10 seminal articles for laparoscopic sleeve gastrectomy.

BACKGROUND: The Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) Masters Program includes eight distinct clinical pathways. The Bariatric Surgery Pathway focuses on three anchoring procedures, including the laparoscopic sleeve gastrectomy (LSG) which is the most commonly performed bariatric procedure in the United States. In this article, we present and discuss the top 10 seminal articles regarding the LSG. METHODS: The literature was systematically searched to identify the most cited papers on LSG. The SAGES Metabolic and Bariatric Surgery committee reviewed the most cited article list, and using expert consensus elected the seminal articles deemed most pertinent to LSG. These articles were reviewed in detail by committee members and are presented here. RESULTS: The top 10 most cited sentinel papers on LSG focus on operative safety, outcomes, surgical technique, and physiologic changes after the procedure. A summary of each paper is presented, including expert appraisal and commentary. CONCLUSIONS: The seminal articles presented support the widespread acceptance and use of the LSG by bolstering the understanding of its mechanism of action and by demonstrating its safety and excellent patient outcomes. All bariatric surgeons should be familiar with these 10 landmark articles.

Metabolic and Bariatric Surgeon Criteria-An International Experts' Consensus.

PURPOSE: With the global epidemic of obesity, the importance of metabolic and bariatric surgery (MBS) is greater than ever before. Performing these surgeries requires academic training and the completion of a dedicated fellowship training program. This study aimed to develop guidelines based on expert consensus using a modified Delphi method to create the criteria for metabolic and bariatric surgeons that must be mastered before obtaining privileges to perform MBS. METHODS: Eighty-nine recognized MBS surgeons from 42 countries participated in the Modified Delphi consensus to vote on 30 statements in two rounds. An agreement/disagreement among ≥ 70.0% of the experts was regarded to indicate a consensus. RESULTS: Consensus was reached on 29 out of 30 statements. Most experts agreed that before getting privileges to perform MBS, surgeons must hold a general surgery degree and complete or have completed a dedicated fellowship training program. The experts agreed that the learning curves for the various operative procedures are approximately 25-50 operations for the LSG, 50-75 for the OAGB, and 75-100 for the RYGB. 93.1% of experts agreed that MBS surgeons should diligently record patients' data in their National or Global database. CONCLUSION: MBS surgeons should have a degree in general surgery and have been enrolled in a dedicated fellowship training program with a structured curriculum. The learning curve of MBS procedures is procedure dependent. MBS surgeons must demonstrate proficiency in managing postoperative complications, collaborate within a multidisciplinary team, commit to a minimum 2-year patient follow-up, and actively engage in national and international MBS societies.

The SAGES MASTERS program bariatric surgery pathway selects 10 seminal publications on adjustable gastric banding.

BACKGROUND: Bariatric surgery is one of the clinical pathways of the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) Masters Program, and laparoscopic adjustable gastric banding (LAGB) is one of the three anchoring bariatric procedures. To improve surgeon lifelong learning, the Masters Program seeks to identify sentinel articles of each of the 3 bariatric anchoring procedures. In this article, we present the top 10 articles on LAGB. METHODS: A systematic literature search of papers on LAGB was completed, and publications with the most citations and citation index were selected and shared with SAGES Metabolic and Bariatric Surgery Committee members for review. The individual committee members then ranked these papers, and the top 10 papers were chosen based on the composite ranking. RESULTS: The top 10 sentinel publications on LAGB contributed substantially to the body of literature related to the procedure, whether for surgical technique, novel information, or outcome analysis. A summary of each paper including expert appraisal and commentary is presented here. CONCLUSION: These seminal articles have had significant contribution to our understanding and appreciation of the LAGB procedure. Bariatric surgeons should use this resource to enhance their continual education and acquisition of specialized skills.

The SAGES MASTERS program bariatric surgery pathway selects 10 seminal publications on revisional bariatrics.

BACKGROUND: The Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) Masters Program designated bariatric surgery as a clinical pathway. Among the tiers of the Masters Program, revisional bariatric surgery is the highest tier of "mastery" within the pathway. This article presents the top 10 seminal studies representing the current landscape of revisional bariatrics. METHODS: The literature was systematically searched and seminal articles designated by consensus agreement of the SAGES Metabolic and Bariatric Surgery committee using multiple criteria, including impact on the field, citation frequency, and expert opinion. Articles were reviewed by committee members and presented in summarized fashion. RESULTS: The top 10 papers are presented in grouped thematic categories covering the early evolution of revisional bariatrics, changing criteria for reoperative bariatric surgery, divergence of revision versus conversion bariatric surgery, and recent technologic innovations in revisional bariatric surgery. Each summary is presented with expert appraisal and commentary. CONCLUSION: These seminal papers represent a snapshot of the dynamic field of revisional bariatric surgery and emphasize the need to not only remain current with contemporary trends but also keep a patient-oriented perspective on patient and intervention selection for optimal success.

Current recommendations for procedure selection in class I and II obesity developed by an expert modified Delphi consensus.

Metabolic and bariatric surgery (MBS) is widely considered the most effective option for treating obesity, a chronic, relapsing, and progressive disease. Recently, the American Society of Metabolic and Bariatric Surgery (ASMBS) and the International Federation for the Surgery of Obesity and Metabolic Disorders (IFSO) issued new guidelines on the indications for MBS, which have superseded the previous 1991 National Institutes of Health guidelines. The aim of this study is to establish the first set of consensus guidelines for selecting procedures in Class I and II obesity, using an Expert Modified Delphi Method. In this study, 78 experienced bariatric surgeons from 32 countries participated in a two-round Modified Delphi consensus voting process. The threshold for consensus was set at an agreement or disagreement of ≥ 70.0% among the experts. The experts reached a consensus on 54 statements. The committee of experts reached a consensus that MBS is a cost-effective treatment option for Class II obesity and for patients with Class I obesity who have not achieved significant weight loss through non-surgical methods. MBS was also considered suitable for patients with Type 2 diabetes mellitus (T2DM) and a body mass index (BMI) of 30 kg/m2 or higher. The committee identified intra-gastric balloon (IGB) as a treatment option for patients with class I obesity and endoscopic sleeve gastroplasty (ESG) as an option for patients with class I and II obesity, as well as for patients with T2DM and a BMI of ≥ 30 kg/m2. Sleeve gastrectomy (1) and Roux-en-Y gastric bypass (RYGB) were also recognized as viable treatment options for these patient groups. The committee also agreed that one anastomosis gastric bypass (OAGB) is a suitable option for patients with Class II obesity and T2DM, regardless of the presence or severity of obesity-related medical problems. The recommendations for selecting procedures in Class I and II obesity, developed through an Expert Modified Delphi Consensus, suggest that the use of standard primary bariatric endoscopic (IGB, ESG) and surgical procedures (SG, RYGB, OAGB) are acceptable in these patient groups, as consensus was reached regarding these procedures. However, randomized controlled trials are still needed in Class I and II Obesity to identify the best treatment approach for these patients in the future.

International survey on complications of religious fasting after metabolic and bariatric surgery.

Religious fasting in Ramadan the 9th month of the lunar year is one of five pillars in Islam and is practiced for a full month every year. There may be risks with fasting in patients with a history of metabolic/bariatric surgery (MBS). There is little published evidence on the possible complications during fasting and needs stronger recommendations and guidance to minimize them. An international survey was sent to surgeons to study the types of complications occurring during religious fasting in patients with history of MBS to evaluate the risk factors to manage and prepare more evidence-based recommendations. In total, 21 centers from 11 countries participated in this survey and reported a total of 132 patients with complications occurring during religious fasting after MBS. The mean age of patients with complications was 36.65 ± 3.48 years and mean BMI was 43.12 ± 6.86 kg/m2. Mean timing of complication occurring during fasting after MBS was 14.18 months. The most common complications were upper GI (gastrointestinal) symptoms including [gastroesophageal reflux disease (GERD), abdominal pain, and dyspepsia], marginal ulcers and dumping syndrome in 24% (32/132), 8.3% (11/132) and 23% (31/132) patients respectively. Surgical management was necessary in 4.5% of patients presenting with complications (6/132) patients due to perforated marginal or peptic ulcer in Single Anastomosis Duodenoileostomy with Sleeve gastrectomy (SADI-S), one anastomosis gastric bypass (OAGB) and sleeve gastrectomy (SG), obstruction at Jejunojenostomy after Roux-en-Y gastric bypass (RYGB) (1/6) and acute cholecystitis (1/6). Patients after MBS should be advised about the risks while fasting including abdominal pain, dehydration, and peptic ulcer disease exacerbation, and a thorough review of their medications is warranted to minimize complications.

Management of abdominal wall hernias in patients with severe obesity.

Obesity is a risk factor for abdominal wall hernia development and hernia recurrence. The management of these two pathologies is complex and often entwined. Bariatric and ventral hernia surgery require careful consideration of physiologic and technical components for optimal outcomes. In this review, a multidisciplinary group of Society of American Gastrointestinal and Endoscopic Surgeons' bariatric and hernia surgeons present the various weight loss modalities available for the pre-operative optimization of patients with severe obesity and concurrent hernias. The group also details the technical aspects of managing abdominal wall defects during weight loss procedures and suggests the optimal timing of definitive hernia repair after bariatric surgery. Since level one evidence is not available on some of the topics covered by this review, expert opinion was implemented in some instances. Additional high-quality research in this area will allow for better recommendations and therefore treatment strategies for these complex patients.

Phase 2 randomised placebo-controlled trial of spironolactone and dexamethasone versus dexamethasone in COVID-19 hospitalised patients in Delhi.

BACKGROUND: In this phase 2 randomised placebo-controlled clinical trial in patients with COVID-19, we hypothesised that blocking mineralocorticoid receptors using a combination of dexamethasone to suppress cortisol secretion and spironolactone is safe and may reduce illness severity. METHODS: Hospitalised patients with confirmed COVID-19 were randomly allocated to low dose oral spironolactone (50 mg day 1, then 25 mg once daily for 21 days) or standard of care in a 2:1 ratio. Both groups received dexamethasone 6 mg daily for 10 days. Group allocation was blinded to the patient and research team. Primary outcomes were time to recovery, defined as the number of days until patients achieved WHO Ordinal Scale (OS) category ≤ 3, and the effect of spironolactone on aldosterone, D-dimer, angiotensin II and Von Willebrand Factor (VWF). RESULTS: One hundred twenty patients with PCR confirmed COVID were recruited in Delhi from 01 February to 30 April 2021. 74 were randomly assigned to spironolactone and dexamethasone (SpiroDex), and 46 to dexamethasone alone (Dex). There was no significant difference in the time to recovery between SpiroDex and Dex groups (SpiroDex median 4.5 days, Dex median 5.5 days, p = 0.055). SpiroDex patients had significantly lower D-dimer levels on days 4 and 7 (day 7 mean D-dimer: SpiroDex 1.15 µg/mL, Dex 3.15 µg/mL, p = 0.0004) and aldosterone at day 7 (SpiroDex 6.8 ng/dL, Dex 14.52 ng/dL, p = 0.0075). There was no difference in VWF or angiotensin II levels between groups. For secondary outcomes, SpiroDex patients had a significantly greater number of oxygen free days and reached oxygen freedom sooner than the Dex group. Cough scores were no different during the acute illness, however the SpiroDex group had lower scores at day 28. There was no difference in corticosteroid levels between groups. There was no increase in adverse events in patients receiving SpiroDex. CONCLUSION: Low dose oral spironolactone in addition to dexamethasone was safe and reduced D-dimer and aldosterone. Time to recovery was not significantly reduced. Phase 3 randomised controlled trials with spironolactone and dexamethasone should be considered. TRIAL REGISTRATION: The trial was registered on the Clinical Trials Registry of India TRI: CTRI/2021/03/031721, reference: REF/2021/03/041472. Registered on 04/03/2021.

Best practice approach for redo-surgeries after sleeve gastrectomy, an expert's modified Delphi consensus.

BACKGROUND: Sleeve gastrectomy (SG) is the most common metabolic and bariatric surgical (MBS) procedure worldwide. Despite the desired effect of SG on weight loss and remission of obesity-associated medical problems, there are some concerns regarding the need to do revisional/conversional surgeries after SG. This study aims to make an algorithmic clinical approach based on an expert-modified Delphi consensus regarding redo-surgeries after SG, to give bariatric and metabolic surgeons a guideline that might help for the best clinical decision. METHODS: Forty-six recognized bariatric and metabolic surgeons from 25 different countries participated in this Delphi consensus study in two rounds to develop a consensus on redo-surgeries after SG. An agreement/disagreement ≥ 70.0% on statements was considered to indicate a consensus. RESULTS: Consensus was reached for 62 of 72 statements and experts did not achieve consensus on 10 statements after two rounds of online voting. Most of the experts believed that multi-disciplinary team evaluation should be done in all redo-procedures after SG and there should be at least 12 months of medical and supportive management before performing redo-surgeries after SG for insufficient weight loss, weight regain, and gastroesophageal reflux disease (GERD). Also, experts agreed that in case of symptomatic GERD in the presence of adequate weight loss, medical treatment for at least 1 to 2 years is an acceptable option and agreed that Roux-en Y gastric bypass is an appropriate option in this situation. There was disagreement consensus on efficacy of omentopexy in rotation and efficacy of fundoplication in the presence of a dilated fundus and GERD. CONCLUSION: Redo-surgeries after SG is still an important issue among bariatric and metabolic surgeons. The proper time and procedure selection for redo-surgery need careful considerations. Although multi-disciplinary team evaluation plays a key role to evaluate best options in these situations, an algorithmic clinical approach based on the expert's consensus as a guideline can help for the best clinical decision-making.

Weight loss and atrial fibrillation: a review.

PURPOSE OF REVIEW: Despite technological advancements in catheter ablation, patients with atrial fibrillation often require multiple ablations, with diminishing returns depending on duration and persistence. Although early ablation is vital, modification of atrial fibrillation disease can be achieved with modification of existing risk factors. Obesity is an important modifiable risk factor, but there does not appear to be a consensus on the best method or goal for weight reduction. RECENT FINDINGS: The relationship between atrial fibrillation and obesity has been acknowledged. This review examines the clinical evidence demonstrating the benefit of weight reduction in the management of atrial fibrillation. In particular, this review compares the different approaches of recent studies. SUMMARY: On the basis of the literature, the authors recommend a structured weight loss programme with dietary and behavioural modifications individualized to each patient and including the implementation of physical activity. Consideration of bariatric surgery is appropriate in certain patients with obesity.

Long-Term Outcomes of Bariatric Surgery in Idiopathic Intracranial Hypertension Patients.

BACKGROUND: Idiopathic intracranial hypertension (IIH), a rare neurological disorder, has limited effective long-term treatments. Bariatric surgery has shown short-term promise as a management strategy, but long-term efficacy has not been evaluated. We investigated IIH-related outcomes 4 to 16 years postsurgery. MATERIALS AND METHODS: This cross-sectional retrospective cohort study included Intracranial Hypertension Registry (IHR) participants with existing medical records that completed a bariatric surgery questionnaire at least 4 years postsurgery. Two physicians independently evaluated the IIH disease course at bariatric surgery and at the time of the questionnaire using detailed medical records. Determinations of improvements were based on within-participant comparisons between the 2 time points. IIH-related outcomes were then combined with bariatric surgery information and outcomes to assess the relationship between weight loss and alterations in IIH. RESULTS: Among participants that underwent bariatric surgery and met study criteria (n=30) the median body mass index (BMI) at the time of surgery was 45.0 [interquartile range (IQR): 39.8-47.0], dropped to a postsurgical nadir of 27.3 (IQR: 22.8-33.1), and rose to 33.4 (IQR: 29.9-41.7) at the time of the questionnaire. Improvements in the IIH disease course at time of the questionnaire occurred in 37% of participants. However, there was a notable association between durable weight loss and IIH improvement as 90% (9 of 10) of participants that attained and maintained a BMI of 30 or below displayed improvement. CONCLUSIONS: Attaining and maintaining a BMI of 30 or below was associated with long-term improvement in the IIH disease course, including improved disease management and amelioration of signs and symptoms of participants of the IHR.

Duodenal switch without versus with laparoscopic cholecystectomy: a perioperative risk comparative analysis of the MBSAQIP database (2015-2019).

BACKGROUND: The results of concurrent cholecystectomy with Roux-en Y gastric bypass and sleeve gastrectomy have been well elucidated. Large-scale data on the outcomes of concomitant cholecystectomy during biliopancreatic diversion with duodenal switch (BPD-DS) are still lacking. Our study aimed to explore whether simultaneous cholecystectomy with BPD-DS alters the 30-day postoperative outcomes. METHODS: We conducted a retrospective analysis of the MBSAQIP database between 2015 and 2019. Propensity-score matching (PSM) in BPD-DS with cholecystectomy (Group 1) and BPD-DS without cholecystectomy (Group 2) cohorts was performed (PSM ratio 1:2). The two groups were matched for a total of 21 baseline variables including age, gender, BMI, ASA class, and other medical comorbidities and conditions. The 30-day postoperative morbidity, mortality, reoperation, reintervention, and readmissions were obtained. RESULTS: Initially, 568 patients in Group 1 and 5079 in Group 2 were identified. After performing PSM, 564 and 1128 patients respectively were compared. The BPD-DS with cholecystectomy group reported a higher rate of reoperation and reintervention compared to BPD-DS alone (3.9% versus 2.4% and 3.2% versus 2%, respectively), even though it did not reach statistical significance. The intervention time was significantly higher in Group 1 compared to Group 2 (192.4 ± 77.6 versus 126.4 ± 61.4 min). Clavien-Dindo complications (1-5) were similar between these two PSM cohorts. CONCLUSION: Concomitant cholecystectomy during BPD-DS increases operative times but does not affect the other outcomes. Based on our results, the decision of cholecystectomy at the time of BPD-DS should be left to the surgeon's judgment.

Association between body mass index, body image and self-esteem with sexual function: A survey of young women in Singapore.

Introduction: Obesity is thought to be a negative predictor of sexual function, but the relationship between body mass index (BMI) and sexual function has been inconsistent. Other factors such as body image and self-esteem may mediate this relationship. This study examined the association of BMI, body image and self-esteem with sexual function in young women. Method: A total of 514 sexually active women aged 21 to 35 years completed an anonymised online questionnaire that used 3 scales to assess body image, self-esteem and female sexual function: Body Image States Scale (BISS), Rosenberg Self-Esteem Scale (RSES) and Female Sexual Function Index (FSFI). Higher scores for BISS, RSES and FSFI indicate more positive body image, higher self-esteem and better sexual function, respectively. Spearman correlation assessed the association among BMI, BISS and RSES scores, and with FSFI scores. Linear and multivariable logistic regression identified risk factors associated with sexual dysfunction (FSFI <26.55). Results: BISS and RSES scores significantly correlated with FSFI scores (r=0.27 and r=0.32, respectively; both P<0.001), indicating that better body image and self-esteem were associated with better sexual function. Risk factors for sexual dysfunction were lower BISS and RSES scores, being married (odds ratio [OR] 1.52; 95% confidence interval [CI] 1.07-2.15), having 1 child (OR 2.45; 95% CI 1.26-4.77) and having a perceived mental condition (OR 3.02; 95% CI 1.44-6.33). Factors in lack of sexual dysfunction include being of Malay ethnicity (OR 0.38; 95% CI 0.21-0.71) and being overweight (OR 0.46; 95% CI 0.27-0.78). Conclusion: Women with poorer body image and lower self-esteem were more likely to have sexual dysfunction. These perceptions and states did not correlate with being overweight, and were better predictors over BMI to identify the population at-risk.

Post-COVID-19 mucormycosis: A prospective, observational study in patients undergoing surgical treatment.

Background and Aims: Post the second wave of COVID-19 in India, our institute became a dedicated center for managing COVID-19-associated mucormycosis (CAM), but there was a paucity of data regarding perioperative considerations in these patients. The objectives of present study was to describe the preoperative clinical profile, the perioperative complications and outcome of CAM patients undergoing urgent surgical debridement. Material and Methods: This prospective observational study was conducted on CAM patients presenting for surgical debridement from July to September 2021. During preoperative visits, evaluation of extent of disease, any side effects of ongoing medical management and post-COVID-19 systemic sequalae were done. The details of anaesthetic management of these patients including airway management, intraoperative haemodynamic complications and need for perioperative blood transfusion were noted. Results: One hundred twenty patients underwent surgical debridement; functional endoscopic sinus surgery (FESS) was carried out in 63% of patients, FESS with orbital exenteration in 17.5%, and maxillectomy in 12.5%. Diabetes mellitus was found in 70.8% and post-COVID new onset hyperglycemia in 29.1% of patients. Moderate-to-severe decline in post-COVID functional status (PCFS) scale was observed in 73.2% of patients, but with optimization, only 5.8% required ICU management. The concern during airway management was primarily difficulty in mask ventilation (17.5%). Intraoperatively, hemodynamic adverse events responded to conventional treatment for hypotension, judicious use of fluids and blood transfusion. Perioperatively, 10.8% of patients required blood transfusion and 4.2% of patients did not survive. Non-surviving patients were older, with a more aggressive involvement of CAM, and had comorbidities and a greater decline in functional capacity. Conclusion: A majority of patients reported a moderate-to-severe decline in PCFS that required a preoperative multisystem optimization and a tailored anesthetic approach for a successful perioperative outcome.

Evaluation of Performance of Detection of Immunoglobulin G and Immunoglobulin M Antibody Against Spike Protein of SARS-CoV-2 by a Rapid Kit in a Real-Life Hospital Setting.

Background: Antibody testing is often used for serosurveillance of coronavirus disease 2019 (COVID-19). Enzyme-linked immunosorbent assay and chemiluminescence-based antibody tests are quite sensitive and specific for such serological testing. Rapid antibody tests against different antigens are developed and effectively used for this purpose. However, their diagnostic efficiency, especially in real-life hospital setting, needs to be evaluated. Thus, the present study was conducted in a dedicated COVID-19 hospital in New Delhi, India, to evaluate the diagnostic efficacy of a rapid antibody kit against the receptor-binding domain (RBD) of the spike protein of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Methods: Sixty COVID-19 confirmed cases by reverse transcriptase-polymerase chain reaction (RT-PCR) were recruited and categorized as early, intermediate, and late cases based on the days passed after their first RT-PCR-positive test report, with 20 subjects in each category. Twenty samples from pre-COVID era and 20 RT-PCR-negative collected during the study period were taken as controls. immunoglobulin M (IgM) and immunoglobulin G (IgG) antibodies against the RBD of the spike (S) protein of SARS-CoV-2 virus were detected by rapid antibody test and compared with the total antibody against the nucleocapsid (N) antigen of SARS-CoV-2 by electrochemiluminescence-based immunoassay (ECLIA). Results: The detection of IgM against the RBD of the spike protein by rapid kit was less sensitive and less specific for the diagnosis of SARS-CoV-2 infection. However, diagnostic efficacy of IgG by rapid kit was highly sensitive and specific when compared with the total antibody against N antigen measured by ECLIA. Conclusion: It can be concluded that detection of IgM against the RBD of S protein by rapid kit is less effective, but IgG detection can be used as an effective diagnostic tool for SARS-CoV-2 infection in real-life hospital setting.

Reoperations after sleeve gastrectomy: a dual academic institutional experience.

BACKGROUND: Although laparoscopic sleeve gastrectomy (LSG) is the most common bariatric operation performed worldwide, patients can experience complications and poor outcomes that warrant reoperations. The incidence, indications, and outcomes of reoperations are not well understood. OBJECTIVE: To describe indications and outcomes for reoperations after LSG. SETTING: Two academic, tertiary care hospitals. METHODS: We performed a retrospective observational cohort review of institutional Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program data from 2014-2018 and reviewed charts of all reoperations after LSG. We analyzed demographics, preoperative symptoms and work-up, and postoperative outcomes. RESULTS: Fifty-seven reoperations after LSG represented 3.0% of 1965 bariatric cases performed. Most LSGs (56.1%) were performed outside our academic centers. Median time to reoperation and follow-up were 2.63 and 1.2 years, respectively. Conversion to gastric bypass was the most common reoperation (77.2%). More than half of the patients (52.6%) had multiple indications for reoperation. Reflux was the most common primary indication for reoperation (47.3%), followed by incisural strictures (20.1%), inadequate weight loss (17.5%), and leak/fistulae (12.2%). Reoperations were most successful when performed for reflux (92.5%) and oral intolerance from strictures (92%), whereas only 71.4% of leak/fistulas resolved. Surgery for inadequate weight loss resulted in total weight loss of 24.7 ± 10.1%. Complications occurred in 36.2% of cases but varied by indication. CONCLUSION: Symptoms and complications after LSG can persist, and patients may require reoperation. Reoperations can successfully treat the primary indications for reoperation and should be offered, but they have higher complication rates than initial operations.
