Improving oxygenation in a patient with respiratory failure due to morbid obesity by applying airway pressure release ventilation: a case report.

INTRODUCTION: Morbidly obese patients occasionally have respiratory problems owing to hypoventilation. Airway pressure release ventilation is one of the ventilation settings often used for respiratory management of acute respiratory distress syndrome. However, previous reports indicating that airway pressure release ventilation may become a therapeutic measure as ventilator management in morbid obesity with respiratory failure is limited. We report a case of markedly improved oxygenation in a morbidly obese patient after airway pressure release ventilation application. CASE REPORT: A 50s-year-old Asian man (body mass index 41 kg/m2) presented with breathing difficulties. The patient had respiratory failure with a PaO2/FIO2 ratio of approximately 100 and severe atelectasis in the left lung, and ventilator management was initiated. Although the patient was managed on a conventional ventilate mode, oxygenation did not improve. On day 11, we changed the ventilation setting to airway pressure release ventilation, which showed marked improvement in oxygenation with a PaO2/FIO2 ratio of approximately 300. We could reduce sedative medication and apply respiratory rehabilitation. The patient was weaned from the ventilator on day 29 and transferred to another hospital for further rehabilitation on day 31. CONCLUSION: Airway pressure release ventilation ventilator management in morbidly obese patients may contribute to improving oxygenation and become one of the direct therapeutic measures in the early stage of critical care.

Safety and efficacy of glucagon-like peptide-1 (GLP-1) receptor agonists in patients with weight regain or insufficient weight loss after metabolic bariatric surgery: A systematic review and meta-analysis.

INTRODUCTION: Weight regain and insufficient weight loss are major challenges after metabolic bariatric surgery (MBS), affecting patients' comorbidities and quality of life. The current systematic review and meta-analysis aim to assess the efficacy and safety of GLP-1 receptor agonists (GLP-1 RA) in patients with weight regain or insufficient weight loss after MBS. METHODS: A systematic search was conducted across PubMed, Embase, Scopus, and Web of Science databases to find the relevant studies. RESULTS: A total of 19 articles were included. The highest doses of liraglutide and semaglutide were 3 mg per day and 1 mg once weekly, respectively, in the included studies. The mean differences in weight and body mass index after treatment were -7.02 kg or 3.07 kg/m2, -8.65 or -5.22 kg/m2, and -6.99 kg or -3.09 kg/m2 for treatment durations of ≤ 6 months, 6-12 months, and >12 months with liraglutide, respectively. Additionally, weekly semaglutide showed significantly greater weight loss compared to daily liraglutide, with a mean difference of 4.15 kg. Common complications included nausea (19.1%), constipation (8.6%), abdominal pain (3.7%), and vomiting (2.4%). CONCLUSION: Using GLP-1 RA is a safe and effective treatment for weight regain and insufficient weight loss after MBS.

The Outcome of Metabolic and Bariatric Surgery in Morbidly Obese Patients with Different Genetic Variants Associated with Obesity: A Systematic Review.

Metabolic and bariatric surgery (MBS) effectively treats obesity and related comorbidities, though individual responses vary. This systematic review examines how genetic variants influence MBS outcomes in morbidly obese patients. A comprehensive search in PubMed, Embase, Medline, and the Cochrane Library identified 1572 studies, with 52 meeting the inclusion criteria. Two reviewers independently filtered and selected studies, including relevant cross-references. Research focused on polymorphisms in genes such as UCP2, UCP3, 5-HT2C, MC4R, FKBP5, FTO, CAT haplotypes, LYPAL-1, PTEN, FABP-2, CNR1, LEP656, LEP223, GLP-1R, APOA-1, APOE, ADIPOQ, IL-6, PGC1a, TM6SF2, MBOAT7, PNPLA3, TCF7L2, ESR1, GHSR, GHRL, CD40L, DIO2, ACSL5, CG, TAS2R38, CD36, OBPIIa, NPY, BDNF, CLOCK, and CAMKK2. Most studies explored associations with post-surgery weight loss, while some examined metabolic, cardiovascular, taste, and eating behavior effects as well. Understanding the role of genetic factors in weight loss and metabolic outcomes post-MBS can help tailor personalized treatment plans for improved efficacy and long-term success. Further research with larger sample sizes and extended follow-up is needed to clarify the effects of many genetic variants on MBS outcomes in morbidly obese patients.

Cancer incidence following bariatric surgery in renal transplant recipients: a retrospective multi-center analysis.

BACKGROUND: Obesity, a known independent risk factor for developing malignancy. Additionally, renal transplant recipients (RTR) confer a 2- to 4-fold increased risk of overall malignancies with an excess absolute risk of .7% per year. While transplant recipients are at risk for obesity and malignancy, the effect of bariatric surgery (BS) in the posttransplantation setting is not well known. OBJECTIVES: Our study primarily evaluated the impact of BS on cancer incidence in RTR with severe obesity in the posttransplantation setting. Weight loss outcomes were analyzed secondarily. SETTING: University Hospital. METHODS: A retrospective study using TriNetX database was developed to analyze cancer outcomes in RTR with posttransplantation BS versus RTR without BS from 2000 to 2023. After the exclusion process and propensity matching, both cohorts consisted of 153 patients. RESULTS: RTR-BS had a significantly lower incidence of overall cancer and transplant-related cancers (P < .05). No significant difference was identified in cutaneous, gastrointestinal, and reproductive cancers. Percent Excess Weight Loss (%EWL) was significantly lower in RTR-only cohort (11.4%) versus RTR-BS cohort (57.8%) at 5 years. Sleeve gastrectomy (SG) patients (73.19%) had significantly higher %EWL than Roux en-Y gastric bypass (RYGB) patients (49.33%) at 3 years. No difference in cancer incidence was noted between SG and RYGB patients. CONCLUSION: Postrenal transplantation BS had a diminishing effect on overall and transplant-related cancer incidence in RTR with severe obesity. Significant weight loss was also demonstrated with post-renal transplantation BS.

Class III Obesity as a Risk Factor for Persistent Asthma.

BACKGROUND: The burden of asthma remains steady with no decline observed in the past few decades. Obesity prevalence has been steadily increasing with a rate of 41.9% in the United States between 2017-2020. Obesity is an inflammatory chronic condition that may partially contribute to the burden and severity of asthma. This study aimed to examine whether the association between obesity and asthma varies with the categories of obesity (class I, II, and III) and persistent asthma (mild, moderate, and severe asthma). We hypothesized that subjects with elevated body mass index (BMI) are more likely to be diagnosed with persistent asthma than subjects without obesity with asthma. METHODS: As a retrospective and cross-sectional study, this study used a total of 1,977 records of subjects with asthma (age ≥ 19 y) hospitalized in Nevada between 2016-2021. BMI and persistent asthma were evaluated as the main exposure and outcome of interest. Logistic regression was used to estimate the magnitude of the association between obesity and persistent asthma. RESULTS: Among the selected subject records, subjects with obesity were more likely to be diagnosed with persistent asthma compared to subjects without obesity (odds ratio 1.50 [CI 1.10-2.05]). Subgroup analyses revealed that subjects with class III obesity (BMI ≥ 40) were more likely than subjects without obesity to be diagnosed with mild persistent asthma (odds ratio 2.21 [CI 1.18-4.16]) and severe persistent asthma (odds ratio 1.74 [CI 1.12-2.70]). CONCLUSIONS: Obesity was identified as a risk factor for persistent asthma, particularly class III obesity. This in turn increases the potential for greater health care utilization and economic burden. Public health and clinical interventions are necessary among those with comorbid asthma and obesity.

The effect of obesity on the outcomes of laparoscopic adrenal surgery in patients with Cushing syndrome.

Purpose: The aim of this study is to investigate the effect of obesity on the results of laparoscopic adrenal surgery in patients with Cushing syndrome. Methods: This retrospective study was performed in Department of General Surgery at Erciyes University School of Medicine between January 2010 and January 2023. Our analysis included Cushing syndrome patients who underwent unilateral laparoscopic adrenalectomy (LA) with the transabdominal lateral approach. All patients were evaluated in terms of age, sex, tumor diameter, body mass index (BMI), American Society of Anesthesiologists physical status classification, morbidities, surgery history, tumor side, operative time, conversion to open surgery, complications, and length of hospital stay. Results: A total of 90 patients (75 females and 15 males) underwent a transperitoneal LA. Patients were divided into 2 groups according to their BMI: obese group (≥30 kg/m2; n = 53, 58.8%) and nonobese group (<30 kg/m2; n = 37, 41.2%). All patients were classified into 3 subgroups: obese patient group, BMI ≥30-39 kg/m2 (n = 23); morbidly obese patient group, BMI ≥40 kg/m2 (n = 14); and nonobese patient group, BMI <30 kg/m2 (n = 53). There was no significant difference in intraoperative complications, conversion to open surgery, operative time, or length of hospital stay between the groups. Only conversion to open surgery was a risk factor for postoperative complications in univariate and multivariate analyses (odds ratio, 15.4; 95% confidence interval, 1.277-185.599; P = 0.031). Conclusion: Our results showed that LA is safe and effective in patients with Cushing syndrome with morbid obesity, allowing acceptable morbidity and length of hospital stay.

Bariatric and general surgical procedures in obese patients with a history of venous thromboembolism and concurrent anticoagulation therapy.

OBJECTIVE: The objective of this study was to examine the use and outcomes of perioperative anticoagulation (AC) in obese patients with a known history of venous thromboembolism event (VTE). METHOD: A retrospective review of a prospective database for patients with a VTE history undergoing bariatric and general surgery at a single center (1/2008-12/2017) was performed. Factors assessed included demographics, surgical details, and outcomes. RESULTS: Sixty-five patients underwent 76 procedures: 46 females (71%); mean age 51 years (range 26-73), mean weight 284 pounds (range 110-558), mean body mass index 45 (range 19-87). Comorbidities include hypertension (60%), gastroesophageal reflux disease (54%), osteoarthritis (49%), obstructive sleep apnea (45%), and diabetes (37%). Operations: 22 general surgeries (29%), 20 sleeve gastrectomies (26%), 12 revisions/conversions (16%), 12 Roux-en-Y gastric bypasses (16%), and 10 gastric bands (13%). Modalities: 67% laparoscopic, 28% robotic, and 5% open. Twenty-two patients (34%) had a pre-operative inferior vena cava filter placed with no complications. The mean length of stay was 4.4 days (range 1-31). Complications: seven 30-day readmissions (9%), one 30-day reoperation (1%), and two 90-day VTEs (3%). Thirty-day readmissions: four for inability to tolerate PO, two for small bowel obstruction, and one for symptomatic anastomotic ulcer. CONCLUSIONS: In our patients, post-operative AC could be started without an increased risk of bleeding in patients with a history of VTE undergoing bariatric surgery.

La estancia media fue de 4.4 días (rango: 1-31). Complicaciones: 7 reingresos a los 30 días (9%), 1 reoperación a los 30 días (1%), 2 TEV a los 90 días (3%). Reingresos a los 30 días: 4 por incapacidad para tolerar la vía oral, 2 obstrucciones de intestino delgado y 1 úlcera anastomótica sintomática. CONCLUSIONES: En nuestros casos, la anticoagulación posoperatoria pudo iniciarse sin aumento del riesgo de sangrado en pacientes con antecedentes de TVE sometidos a cirugía bariátrica.

Improvement of Metabolic-Associated Fatty Liver Disease by Magnetic Resonance Spectroscopy in Morbidly Obese Women Undergoing Roux-en-Y Gastric Bypass, following a Postoperative Mediterranean-like Diet.

(1) Background: Bariatric surgery has demonstrated the capacity to improve metabolic-associated fatty liver disease (MAFLD) in patients with morbid obesity. In addition, the Mediterranean diet contains anti-inflammatory, anti-oxidative, and anti-fibrotic components, promoting a beneficial effect on MAFLD. This study aimed to assess the improvement of MAFLD, specifically liver steatosis, in morbidly obese patients undergoing Roux-en-Y gastric bypass (RYGB) and following a hypocaloric Mediterranean-like diet. (2) Methods: A prospective observational pilot study of 20 patients undergoing RYGB was conducted. The participants underwent a magnetic resonance spectroscopy study 2 weeks before the surgical act and one year postoperatively to assess the percentage of lipid content (PLC). The adherence to the Mediterranean diet was determined by the KIDMED test 1 year after surgery. (3) Results: Mean baseline PLC was 14.2 ± 9.4%, and one year after surgery, it decreased to 4.0 ± 1.8% (p < 0.001). A total of 12 patients (60%) were within the range of moderate adherence to the Mediterranean diet, whereas 8 patients (40%) showed a high adherence. The patients with high adherence to the Mediterranean diet presented significantly lower values of postoperative PLC. (4) Conclusions: Liver steatosis significantly reduces after RYGB. This reduction is further improved when associated with a high adherence to a Mediterranean diet.

Successful use of remimazolam combined with remifentanil for painless gastroscopy in a patient with morbid obesity: a case report.

Backgroud: In recent years, as the number of people with obesity has surged, the number of morbidly obese patients has also grown. The pathophysiological changes in morbid obesity can lead to combined lung diseases, which may result in hypoventilation, hypoxemia, acute upper airway obstruction, acute respiratory distress syndrome, and sleep apnea syndrome, posing serious challenges to anesthesia management. Here, we describe a case of the administration of remimazolam combined with remifentanil in a patient with morbid obesity undergoing gastroscopy. This has rarely been reported in clinical practice, and we present our management experience here with the aim of providing a reference for clinical work. Case presentation: We report the case of a 32-year-old male hypertensive patient with a height of 180 cm, weight of 145 kg, and body mass index of 44.8 kg/m2. The patient's main complaint was intermittent hunger pain for more than 1 year, and duodenal polyps were found. Considering the patient's morbid obesity and the combination of sleep apnea syndrome and hypertension, we administered remimazolam along with remifentanil to ensure perioperative safety. Conclusion: The procedure lasted 30 min, and the anesthesia was satisfactory with no complications. Remimazolam combined with remifentanil intravenous anesthesia is safe for short gastroscopy in patients with morbidly obesity. The administration of a small dose of split-titration delivery facilitates the maintenance of stable vital signs.

Role of Bariatric Surgery in Patients With Endometrial Cancer: A Case Report and Review of Literature.

Objective: The standard surgery for endometrial cancer can be deferred in some situations, including morbid obesity, comorbidities, and the patient's desire for fertility. One of the options to improve patients' circumstances is bariatric surgery. Case report: This study presented two patients with stage IA, grade I endometrioid endometrial adenocarcinoma. Both patients had morbid obesity and had comorbidities. In case 1, because of fertility preservation, and in case 2, because of severe comorbidities, hormone therapy was started, followed by bariatric surgery after counseling patients. Both patients had acceptable changes in body mass index during follow-up, so cancer surgery through laparoscopy was done. Both patients did not need adjuvant therapy; months after cancer surgery, there is no recurrence, and their body mass index is also decreasing. Conclusion: Bariatric surgery can improve outcomes in patients with morbid obesity who suffer endometrial cancer.

Prediction Model for Chronological Weight Loss After Bariatric Surgery in Korean Patients.

Purpose: This study aimed to develop a predictive model for monitoring chronological weight loss during the early postoperative period following bariatric surgery in Korean patients with morbid obesity. Materials and Methods: The baseline characteristics and postoperative weight loss outcomes were collected for up to 24 months after surgery in patients who underwent sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB). The factors influencing weight loss outcomes were analyzed, and longitudinal percentile charts were plotted using quantile regression models adjusted for the identified independent factors. Results: The analysis included 491 and 274 patients who underwent SG and RYGB, respectively, of whom 225 (29.4%) were men. A positive association was found between the maximum percentage of total weight loss (%TWL) and female sex, body mass index (BMI) ≥40, and age <40 years. Among patients who reached nadir BMI or had at least 12 months of follow-up data (n=304), 7.6% exhibited inadequate weight loss (TWL <20%). The predictors of insufficient weight loss were older age (>40 years), male sex, and psychological problems. Centile charts were generated for the entire cohort, incorporating age, sex, and the type of procedure as covariates. Conclusion: The percentile charts proposed in the present study can assist surgeons and healthcare providers in gauging patients' progress toward their weight loss goals and determining the timing of adjunctive intervention in poor responders during early postoperative follow-up.

Unveiling the Shadows: A Rare Encounter With Cardiac Tamponade Following Influenza B in a Young Female.

Influenza B infection, although primarily recognized for respiratory symptoms, can lead to rare but severe cardiac complications such as pericardial effusion and cardiac tamponade. We present a case of a 33-year-old female with morbid obesity who initially exhibited flu-like symptoms, was subsequently diagnosed with influenza B infection, and was discharged with symptomatic treatment. Despite initial discharge, she returned with worsening weakness, gastrointestinal symptoms, and shortness of breath. Imaging studies confirmed pericardial effusion with early signs of tamponade, necessitating an emergent intervention. The patient underwent subxiphoid pericardial window and fluid removal, followed by colchicine treatment to prevent recurrence. Our case highlights the importance of recognizing and promptly managing rare influenza-related complications, particularly in patients without significant comorbidities. It underscores the value of a proactive approach, utilizing point-of-care ultrasound and echocardiography for early diagnosis and intervention to mitigate mortality and morbidity risks associated with pericarditis and cardiac tamponade secondary to influenza B.

Early safety of endoscopic sleeve gastroplasty in super obesity (body mass index > 50).

BACKGROUND: The prevalence of super obesity (body mass index [BMI] > 50) continues to rise. However, the adoption of bariatric surgery in this population remains very low. There are limited studies evaluating the utility of endoscopic sleeve gastroplasty (ESG) in super obesity. OBJECTIVES: The purpose of this study is to evaluate the short-term safety profile of ESG in patients with super obesity using data from the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program database. SETTING: United States. METHODS: We retrospectively analyzed patients who underwent ESG and sleeve gastrectomy (SG) from 2016 to 2021. Patients with BMI >50 who underwent ESG were compared to ESG patients with BMI <50 and also SG patients with BMI >50. Primary outcomes included the incidence of severe adverse events (AEs), hospital readmission, reintervention, and reoperation within 30 days of the primary procedure. Secondary outcomes included procedure time, hospital length of stay, and total body weight loss at 30 days. RESULTS: There were no significant differences in AE, reoperations, hospital readmissions, or reinterventions for patients with super obesity undergoing ESG, compared to patients with BMI below 50. Mean total body weight loss was greater in patients with super obesity. There were no significant differences in AEs for patients with super obesity who underwent ESG versus SG, although ESG patients had more hospital readmissions, reinterventions, and reoperations. CONCLUSIONS: ESG may be performed safely, with comparable safety to SG, in patients with BMI as high as 70. However, further studies are needed to validate the feasibility and long-term efficacy prior to clinical implementation.

Evaluating Laparoscopic Sleeve Gastrectomy for Morbid Obesity: A Prospective Follow-Up Study.

Background Laparoscopic sleeve gastrectomy (LSG) has become a primary option within bariatric surgery (BS), exhibiting favorable outcomes in terms of weight reduction and improvement of associated health conditions. This study was conducted to assess the outcomes of LSG in morbid obesity (MO) in terms of weight reduction and improvement of comorbidities. Materials and methods A prospective follow-up study was conducted from January 2021 to January 2023 at the Department of Surgery, 7 Air Force Hospital, Kanpur. The study was approved by the institutional ethical committee with protocol no. IEC/612/2020, including 25 patients diagnosed with MO (BMI >40kg/m2) who underwent LSG. Patients were followed up at 1, 3, 6, and 12 months after surgery to track improvements in comorbidities and weight loss. Pre- and post-operative photos were taken, and any complications during the follow-up period were noted. Results Most participants in the study were middle-aged individuals, and 84% of the cohort had common comorbidities such as hypertension (HTN) and diabetes mellitus (DM). LSG led to significant and sustained weight loss, with patients achieving an average reduction of 31.56 kg by the 12th month following the surgery. Moreover, substantial improvements in comorbidities, particularly HTN (76.9%) and DM (80%), were observed. However, not all comorbidities exhibited similar rates of recovery, highlighting the need for tailored management strategies. Using a correlation test, no significant correlation was found between the percentage over ideal body weight (IBW) and the reduction in excess weight, as indicated by a p-value exceeding 0.05. Conclusion LSG is an effective treatment for severe obesity, delivering significant weight loss and notable improvements in metabolic health and overall quality of life.

Comparison between high transverse and low transverse Pfannenstiel skin incisions during cesarean delivery for morbidly obese patients.

OBJECTIVE: This study aimed to evaluate if placement of transverse cesarean skin incision above or below the overhanging pannus is associated with wound morbidity in morbidly obese patients. STUDY DESIGN: We identified a cohort of patients with body mass index (BMI) ≥40 kg/m2 undergoing cesarean delivery at a single center from 2017-2020 with complete postpartum records. Data was abstracted after institutional review board exemption, and patients were grouped by low transverse or high transverse skin incision. The primary outcome was a composite of wound infection, fascial dehiscence, incisional hernia, therapeutic wound vacuum, and reoperation. Secondary outcomes included the individual components of the composite, blood transfusion, operative time, and immediate neonatal outcome. T test and χ2 were used for continuous and categorical comparisons. Logistic regression was used to compute adjusted odds ratios for categorical outcomes and linear regression to compare operative times adjusting for factors associated with wound complications and surgical duration respectively. RESULTS: 328 patients met inclusion criteria: 65 with high transverse (infraumbilical and supraumbilical) and 263 with low transverse (Pfannenstiel) incision. 11% of patients had wound morbidity; high transverse incision was associated with 3.64-fold increased odds of composite wound morbidity (23.1% vs 8%, aOR 3.64, 95% CI 1.52-8.70) and 5.73-fold increased odds of wound infection (13.8% vs. 4.9%, aOR 5.73, 95% CI 1.83-17.96). Time from skin incision to delivery was 1.87 min longer (11.09 vs 14.98 min, ß = 1.87, 95% CI 0.17-4.61). There was no significant difference in neonatal outcomes, non-low transverse hysterotomy, or total operative time. CONCLUSION: High transverse skin incision for cesarean delivery was strongly associated with increased wound morbidity in morbidly obese patients.

Outcomes after cesarean delivery were assessed for 328 patients with morbid obesity.High transverse skin incision for cesarean delivery was associated with increased wound morbidity and wound infection.Prospective studies will be needed to determine if skin incision placement causes wound morbidity.

[ICG angiography is a safety standard in bariatric surgery]. / ICG-angiografiya kak standart bezopasnosti v bariatricheskoi khirurgii.

OBJECTIVE: To examine the specific characteristics of ICG-angiography during various bariatric interventions. MATERIAL AND METHODS: The study included 329 patients, with 105 (32%) undergoing sleeve gastrectomy (LSG), 98 (30%) undergoing mini-gastricbypass (MGB), 126 (38%) undergoing Roux-en-Y gastric bypass (RGB). Intraoperative ICG angiography was perfomed on all patients at 'control points', the perfusion of the gastric stump was qualitatively and quantitatively assessed. RESULTS: Intraoperative ICG angiography shows that during LSG the angioarchitectonics in the area of the His angle are crucial. The presence of the posterior gastric artery of the gastric main type is a prognostically unfavorable risk factor for the development of ischemic complications. Therefore, to expand the gastric stump it is necessary to suture a 40Fr nasogastric tube and perform peritonization of the staple line. Statistical difference in blood supply at three points were found between and within the two groups of patients (Gis angle area, gastric body, pyloric region) with a p-value <0.001. During MGB, one of the important stages is applying the first (transverse) stapler cassette between the branches of the right and left gastric arteries. This maintains blood supply in anastomosis area, preventing immediate complications such as GEA failure, as well as long-term complications like atrophic gastritis, peptic ulcers, and GEA stenosis. CONCLUSION: ICG angiography is a useful method for intraoperative assessment of angioarchitecture and perfusion of the gastric stump during bariatric surgery. This helps prevent tissue ischemia and reduce the risk of early and late postoperative complications.

Bariatric surgery: trends in utilization, complications, conversions and revisions.

BACKGROUND: Sleeve gastrectomy (SG) increased in popularity after 2010 but recent data suggest it has concerning rates of gastroesophageal reflux and need for conversions. This study aims to evaluate recent trends in the utilization of bariatric procedures, associated complications, and conversions using an administrative claims database in the United States. METHODS: We included adults who had bariatric procedures from 2000 to 2020 with continuous enrollment for at least 6 months in the MarketScan Commercial Claims and Encounters database. Index bariatric procedures and subsequent revisions or conversions were identified using CPT codes. Baseline comorbidities and postoperative complications were identified with ICD-9-CM and ICD-10 codes. Cumulative incidences of complications were estimated at 30-days, 6-months, and 1-year and compared with stabilized inverse probability of treatment weighted Kaplan-Meier analysis. RESULTS: We identified 349,411 bariatric procedures and 5521 conversions or revisions. The sampled SG volume appeared to begin declining in 2018 while Roux-en-Y gastric bypass (RYGB) remained steady. Compared to RYGB, SG was associated with lower 1-year incidence [aHR, (95% CIs)] for 30-days readmission [0.65, (0.64-0.68)], dehydration [0.75, (0.73-0.78)], nausea or vomiting [0.70, (0.69-0.72)], dysphagia [0.55, (0.53-0.57)], and gastrointestinal hemorrhage [0.43, (0.40-0.46)]. Compared to RYGB, SG was associated with higher 1-year incidence [aHR, (95% CIs)] of esophagogastroduodenoscopy [1.13, (1.11-1.15)], heartburn [1.38, (1.28-1.49)], gastritis [4.28, (4.14-4.44)], portal vein thrombosis [3.93, (2.82-5.48)], and hernias of all types [1.36, (1.34-1.39)]. There were more conversions from SG to RYGB than re-sleeving procedures. SG had a significantly lower 1-year incidence of other non-revisional surgical interventions when compared to RYGB. CONCLUSIONS: The overall volume of bariatric procedures within the claims database appeared to be declining over the last 10 years. The decreasing proportion of SG and the increasing proportion of RYGB suggest the specific complications of SG may be driving this trend. Clearly, RYGB should remain an important tool in the bariatric surgeon's armamentarium.

The risk of herpes zoster is positively associated with obesity, especially morbid obesity.

This study aimed to investigate the association between obesity and herpes zoster (HZ) occurrence. This study used data covering 2 million people in Taiwan in 2000, which were obtained from the National Health Insurance Research Database. The cohort study observed aged 20-100 years with obesity from 2000 to 2017 (tracking to 2018). Obesity was indicated by the presence of two or more outpatient diagnoses or at least one admission record. And, obesity was categorized into non-morbid obesity and morbid obesity. Patients with HZ before the index date were excluded. The obesity cohort and control cohort were matched 1:1 according to age, sex, comorbidities, and index year. There were 18,855 patients in both the obesity and control cohorts. The obesity cohort [adjusted hazard ratio (aHR) 1.09] had a higher risk of HZ than the control cohort. Further analysis, the morbid obesity group (aHR 1.47), had a significantly higher risk of HZ than the non-morbid obesity group. Among the patients without any comorbidities, the patients with obesity had a significantly higher risk of developing HZ than the patients without obesity (aHR 1.18). Obese patients are at a higher risk of HZ development, especially in the patients with morbid obesity. Weight reduction is critical for preventing the onset of chronic diseases and decreasing the risk of HZ in patients with obesity.

Incidentally Discovered Giant Benign Ovarian Serous Cystadenoma in Elective Bariatric Surgery.

Ovarian cystadenomas are benign epithelial neoplasms, many of which are of the serous subtype. Most patients present with symptoms such as abdominal pain, bloating, and bladder issues. This patient, who had a BMI of 45, presented with a giant ovarian serous cystadenoma identified during an elective bariatric surgery; interestingly, she was completely asymptomatic at the time of discovery. A large, predominantly cystic pelvic mass with internal septations and soft tissue components, suspicious for ovarian neoplasm, was discovered on a CT abdomen and pelvis with IV contrast. She underwent an exploratory laparotomy with complete resection, right oophorectomy, and ovarian cystectomy. Her postoperative pathology report revealed the mass to be a benign serous cystadenoma. This case serves as an example of how a massive tumor can potentially get overlooked for many years, only to be detected unintentionally in an asymptomatic patient. Healthcare quality is often negatively impacted by the inherent prejudice that many healthcare providers have toward their obese patients. Providers may mistakenly over-attribute a patient's symptoms to their obesity, failing to effectively evaluate the patient's concerns, which could lead to overlooking potentially harmful diagnoses. A comprehensive history and physical exam in all patients, especially those who are obese, is vital in ensuring timely diagnosis and management to improve patient outcomes.
