Introduction: Evidence from Asian studies suggests that minimally-invasive gastrectomy achieves equivalent oncological but improved perioperative outcomes compared to open surgery. Oncological gastric resections are less frequent in European countries. Index procedures may play a role for the learning curve of minimally-invasive gastrectomy. The aim of our study was to evaluate if skills acquired in bariatric surgery allow a safe and oncologically adequate implementation of minimally-invasive gastrectomy in a cohort of european patients., Methods: In this single-center retrospective study, all patients who received primary bariatric surgery between January 2015 and December 2018 and minimally-invasive surgery for gastric cancer treated from June 2019 to January 2023 were evaluated. Primary endpoints were operation time, lymph node yield and lymph node fractions. Secondary endpoints included postoperative complications and oncological outcomes., Results: Learning curves for two surgeons with 350 bariatric procedures and 44 minimally-invasive gastrectomies were analyzed. For bariatric surgery, the mean operation time decreased from initially 82 ± 27 to 45 ± 21 min and 118 ± 28 to 81 ± 36 min for sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB), while the complication rate remained within the international benchmark. For laparoscopic gastrectomy (n = 30), operation times decreased but then remained stable over time. Operation times for the robotic platform were longer (302 ± 60 vs. 390 ± 48 min; p < 0.001) with the learning curve remaining incomplete after 14 procedures. R0 status was achieved in 95.5% of patients; the mean number of lymph nodes retrieved was 37 ± 14 with no differences between the groups. Complete mesogastric excision was more frequently achieved during the later laparoscopic cases whereas it occurred earlier for the robotic group (p = 0.004). Perioperative morbidity was comparable to the European benchmark. Textbook outcome was achieved in 54.4% of the cases., Conclusion: In summary, we could demonstrate a successful skill transfer from bariatric surgery to minimally-invasive laparoscopic oncological gastric surgery enabling safe and oncologically adequate minimally-invasive D2 gastrectomy in a central European patient collective., (© 2024.

Roux-en-Y gastric bypass (RYGB) is the preferred surgical option for patients with proven gastroesophageal reflux disease and obesity grade ≥ II (BMI ≥ 35 kg/m 2 ). Data on simultaneous treatment of larger hiatal hernias during RYGB are scarce. From 2012 until 2022, data from all consecutive patients undergoing gastric bypass procedures were collected and retrospectively analyzed. The characteristics and surgical outcomes of patients undergoing RYGB alone (RYGBa) versus RYGB with simultaneous treatment of a large hiatal hernia (RYGB-HH) were compared. Out of 573 patients who received RYGB, we identified 12 simultaneously treated for large hiatal hernia. The characteristics of RYGB-HH versus RYGBa patients were higher age (55 vs. 44 years; p = 0.004) and lower BMI (39.2 vs. 46.9 kg/m 2 ; p = 0.001). Duration of surgery in the RYGB-HH group was longer (144 min vs. 98 min; p < 0.001), while complications > Clavien-Dindo II were similar compared to the RYGBa group (8.3 vs. 9.4%, p = 0.56). Length of stay did not differ among the groups (4 vs. 5.5 days, p = 0.051). At a median follow-up of 12 months, there was no clinical recurrence of hiatal hernia in the RYGB-HH group. Simultaneous treatment of large hiatal hernias during Roux-en-Y gastric bypass surgery prolongs operation time but seems feasible and safe in the hands of experienced surgeons., (© 2024.

Background and study aims Endoscopic vacuum therapy (EVT) has become the most effective therapeutic option for upper gastrointestinal leakage. Despite its efficiency, this treatment can necessitate a long hospitalization. The aim of this study was to evaluate whether additional use of an over-the-scope-clips (OTSC) closure after successful EVT can shorten leakage therapy. Patients and methods All patients treated with EVT for leakages in the upper gastrointestinal tract at our center from 2012 to 2022 were divided into two propensity matched cohorts (EVT+OTSC vs. EVT only). The EVT+OTSC patients received OSTC application at the end of successful EVT directly after removal of the last sponge. The primary endpoint was the time interval from leakage diagnosis until discharge. Secondary endpoints included EVT efficacy, complications, and nutritional status at discharge. Results A total of 84 matched patients were analyzed. EVT efficacy was 100% in both groups. The time interval from leakage until discharge was significantly shorter in the EVT+OTSC vs. EVT group (33 [19-48] vs. 46 days [29-77] P = 0.004). No patient in the EVT+OTSC group required additional procedures for leakage management, whereas five (12%) in the EVT group needed additional stent placement ( P = 0.021). More patients could be discharged on sufficient oral nutrition in the EVT+OTSC group (98% vs. 60%; P < 0.001). Conclusions The addition of OTSCs after successful EVT is safe and has the potential to shorten leakage therapy, enabling earlier discharge along with better functional outcomes., Competing Interests: Conflict of Interest Alexander Meining is a consultant for OVESCO and co-patentholder for several devices manufactured and distributed by the company.

After bariatric surgery lifelong follow-up is recommended. Evidence of the consequences and reasons for being lost to follow-up (LTFU) is sparse. In this prospective study follow-up data of all patients who underwent bariatric surgery between 2008 and 2017 at a certified obesity centre were investigated. LTFU patients were evaluated through a structured telephone interview. Overall, 573 patients (female/male 70.9%/29.1%), aged 44.1 ± 11.2 years, preoperative BMI 52.1 ± 8.4 kg/m 2 underwent bariatric surgery. Out of these, 33.2% had type 2 diabetes mellitus and 74.4% had arterial hypertension. A total of 290 patients were LTFU, of those 82.1% could be reached. Baseline characteristics of patients in follow-up (IFU) and LTFU were comparable, but men were more often LTFU ( p = 0.01). Reported postoperative total weight loss (%TWL) and improvements of comorbidities were comparable, but %TWL was higher in patients remaining in follow-up for at least 2 years ( p = 0.013). Travel issues were mentioned as the main reason for being LTFU. A percentage of 77.6% of patients reported to regularly supplement micronutrients, while 71.0% stated regular monitoring of their micronutrient status, mostly by primary care physicians. Despite comparable reported outcomes of LTFU to IFU patients, the duration of the in-centre follow-up period affected %TWL. There is a lack of sufficient supplementation and monitoring of micronutrients in a considerable number of LTFU patients.

Background: Retrosternal oesophageal reconstructions with collar anastomoses can become necessary when the stomach is either unavailable for oesophageal replacement, or orthotopic reconstruction is deemed impractical. Our aim was to analyse our results regarding technical approaches and outcomes., Materials and Methods: All patients undergoing primary and secondary oesophageal retrosternal reconstructions with collar anastomoses at our centre (2019-2023) were retrospectively analysed and individual surgical reconstruction options were presented., Results: Overall, twelve patients received primary (n = 5; 42.7%) or secondary (n = 7; 58.3%) reconstructions; ten with colonic interposition and two with gastric pull-up. Male/female ratio was 4:8; median age 66 years (30-87). Charlson-Comorbidity-Score (CCS) was 5 (1-7); 8/12 patients (67%) had ASA-classification score ≥ 3. We observed no conduit necrosis, but one patient (8.3%) with a leakage of the oesophago-colonostomy which was successfully treated by endoscopic vacuum therapy. Four patients (33.3%) acquired nosocomial pneumonia. Additional drainages for pleural fluid collections were necessary in three patients (25%). Overall comprehensive-complication-index (CCI) was 26.2 (0-44.9). Length-of-stay (LOS) was 22 days median (15-40). There was no 90-days mortality. Overall, CCI during the follow-up (FU) period at median 26 months (16-50) was 33.7 (0-100). 10 out of 12 patients were on sufficient oral nutrition at 12 months FU., Conclusion: Primary and secondary oesophageal retrosternal reconstructions encompass diverse entities and typically requires tailored decision-making. These procedures, though rare, are feasible with acceptable complication rates and positive functional outcomes when performed in experienced hands., (© 2024. The Author(s).)

Accurate and timely mortality surveillance is crucial for elucidating risk factors, particularly for emerging diseases. We compared use of COVID-19 keywords on death certificates alone to identify COVID-19 deaths in Minnesota, USA, during 2020-2022, with use of a standardized mortality definition incorporating additional clinical data. For analyses, we used likelihood ratio χ 2 and median 1-way tests. Death certificates alone identified 96% of COVID-19 deaths confirmed by the standardized definition and an additional 3% of deaths that had been classified as non-COVID-19 deaths by the standardized definition. Agreement between methods was >90% for most groups except children, although agreement among adults varied by demographics and location at death. Overall median time from death to filing of death certificate was 3 days; decedent characteristics and whether autopsy was performed varied. Death certificates are an efficient and timely source of COVID-19 mortality data when paired with SARS-CoV-2 testing data.

Objectives: Surveillance systems for unexplained deaths that might have an infectious etiology are rare. We examined the Minnesota Department of Health Unexplained Deaths and Critical Illnesses of Possible Infectious Etiology and Medical Examiner Infectious Deaths (UNEX/MED-X) surveillance system,-a system that expanded postmortem surveillance for infectious diseases during the COVID-19 pandemic by leveraging standard (medical examiner [ME]) and expanded (mortuary) surveillance to identify COVID-19-related deaths., Methods: MEs, coroners, or morticians collected postmortem swabs from decedents with an infectious prodrome or with SARS-CoV-2 exposure before death but with no known recent infectious disease testing. The Minnesota Department of Health Public Health Laboratory used nucleic acid amplification, viral culture, and standard algorithms to test specimens collected postmortem for SARS-CoV-2, influenza virus, and other infectious pathogens. We reviewed UNEX/MED-X data from March 2, 2020, through December 31, 2021, and characterized decedents by location of swab collection (ie, ME or mortuary)., Results: From March 2, 2020, through December 31, 2021, the UNEX/MED-X surveillance system received samples from 182 decedents from mortuaries and 955 decedents from MEs. Mortuary decedents were older than ME decedents (median age, 78 vs 46 y). Seventy-three mortuary decedents (40.1%) and 197 ME decedents (20.6%) had SARS-CoV-2 detections. The UNEX/MED-X system identified 212 COVID-19-related deaths, representing 2.0% of total COVID-19-related deaths in Minnesota. Eighty-nine decedents (42.0%) were from racial and ethnic minority populations, representing 6.1% more COVID-19-related deaths among people from racial and ethnic minority populations than would have been detected without this surveillance system., Practice Implications: Expanded and standard UNEX/MED-X surveillance builds capacity and flexibility for responding to emerging public health threats. Similar programs should be considered elsewhere as resources allow., Competing Interests: Declaration of Conflicting InterestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Introduction: Major postoperative bleeding (mPOB) is the most common complication after bariatric surgery. Its intesity varies from self-limiting to life-threatening situations. Comprehensive decision-making and treatment strategies are mandatory but not established yet., Methods: We retrospectively analyzied our prospectively collected database of our bariatric patients during 2012-2022. The primary study endpoint was major postoperative bleeding (mPOB) defined as hemoglobin drop > 2 g/dl or clinically relevant bleeding requiring intervention (transfusion, endoscopy or surgery). Secondary endpoints were overall complications according to Clavien-Dindo-Classification and comprehensive-complication-index (CCI)., Results: We identified 1017 patients, of whom 667 underwent gastric bypass (GB) and 350 sleeve gastrectomy (SG). Major postoperative bleeding occured in 39 patients (total 3.8%; 5.1% after GB and 2.3% after SG). Patients with mPOB were more often diagnosed with type 2 diabetes (p = 0.039), chronic kidney failure (p = 0.013) or received antiplatelet drug treatment (p = 0.003). The interval from detection to intervention within 24 h was 92.1% (35/39). Blood transfusions were necessary in 20/39 cases (total 51.3%; 45.2% after GB and 75% after SG; p = 0.046). Luminal bleeding only occured after GB (19/31; 61.3%), while all mPOB after SG were intraabdominal (p = 0.002). Reoperations were performed in 21/39 (total 53.8%; 48.4% after GB and 75% after SG; p = 0.067). CCI in patients with mPOB was 34.7 overall, with 31.2 after GB and 47.9 after SG (p = 0.005)., Conclusion: The clinical appearance of mPOB depends on the type of surgery with severe bleedings after SG. We suggest a surgery first approach for mPOB after SG and an endoscopy first approach after GB., (© 2024. The Author(s).)

Background: Gastric (anastomotic or staple-line) leaks after bariatric surgery are rare but potentially life-threatening complications. Endoscopic vacuum therapy (EVT) has evolved as the most promising treatment strategy for leaks associated with upper gastrointestinal surgery., Objective: The aim of this study was to evaluate the efficiency of our gastric leak management protocol in all bariatric patients over a 10-year period. Special emphasis was placed on EVT treatment and its outcome as a primary treatment or as a secondary treatment when other approaches failed., Setting: This study was performed at a tertiary clinic and certified center of reference for bariatric surgery., Methods: In this retrospective single-center cohort study, clinical outcomes of all consecutive patients after bariatric surgery from 2012 to 2021 are reported, with special emphasis placed on gastric leak treatment. The primary endpoint was successful leak closure. Secondary endpoints were overall complications (Clavien-Dindo classification) and length of stay., Results: A total of 1046 patients underwent primary or revisional bariatric surgery, of whom 10 (1.0%) developed a postoperative gastric leak. Additionally, 7 patients were transferred for leak management after external bariatric surgery. Of these, 9 patients underwent primary and 8 patients underwent secondary EVT after futile surgical or endoscopic leak management. The efficacy of EVT was 100%, and there were no deaths. Complications did not differ between primary EVT and secondary treatment of leaks. Length of treatment was 17 days for primary EVT versus 61 days for secondary EVT (P = .015)., Conclusions: EVT for gastric leaks after bariatric surgery led to rapid source control with a 100% success rate both as primary and secondary treatment. Early detection and primary EVT shortened treatment time and length of stay. This study underlines the potential of EVT as a first-line treatment strategy for gastric leaks after bariatric surgery., (Copyright © 2023 American Society for Metabolic and Bariatric Surgery.

Introduction: Internal hernia is one of the most frequent long-term complications after laparoscopic gastric bypass surgery (RYGB). Surgical treatment of an internal hernia itself has risks that can largely be avoided by the implementation of institutional standards and a structured approach., Material and Methods: From 2012 until 2022, we extracted all consecutive bariatric cases from the prospectively collected national database (StuDoQ). Data from all patients undergoing internal hernia repair were then collected from our hospital information management system and retrospectively analyzed. We compared patient characteristics and surgical outcome of patients before and after the implementation of standard operating procedures for institutional and perioperative aspects (first vs. second time span)., Results: Overall, 37 patients were identified (median age 43 years, 86.5% female). Internal hernia was diagnosed after substantial weight loss (17.2 kg/m 2 ) and on average about 34 months after RYGB. Baseline characteristics (age, sex, BMI, achieved total weight loss% and time interval to index surgery were comparable between the two groups). After local standardization, the conversion rate decreased from 52.6 to 5.6% (p = 0.007); duration of surgery from 92 to 39 min (p = 0.003), and length of stay from 7.7 to 2.8 days (p = 0.019)., Conclusion: In this study, we could demonstrate that the surgical therapy of internal hernia after gastric bypass can be significantly improved by implementing institutional and surgical standards. The details described (including a video) may provide valuable information for non-specialized surgeons to avoid pitfalls and improve surgical outcomes., (© 2023. The Author(s).)

During February 7─September 3, 2022, a total of 39 US states experienced outbreaks of highly pathogenic avian influenza A(H5N1) virus in birds from commercial poultry farms and backyard flocks. Among persons exposed to infected birds, highly pathogenic avian influenza A(H5) viral RNA was detected in 1 respiratory specimen from 1 person.

Obesity is a complex chronic disease and requires a long-term multimodal approach. The current treatment algorithm for treatment of obesity mainly consists of a stepwise approach, which starts with a lifestyle intervention followed by or combined with medication treatment, whereas bariatric surgery is often reserved for the last option. This article provides an overview of the currently available conservative medicinal treatment regimens and the currently approved medications as well as medications currently undergoing approval studies with respect to the efficacy and possible side effects. Special attention is paid to the importance of combination treatment of pharmacotherapy and surgery in the sense of a multimodal treatment. The data so far show that using a multimodal approach an improvement in the long-term weight loss and metabolic benefits can be achieved for the patients., (© 2023.

Since February 12, 2020, approximately 6.5 million cases of SARS-CoV-2 infection, the cause of coronavirus disease 2019 (COVID-19), and 190,000 SARS-CoV-2-associated deaths have been reported in the United States (1,2). Symptoms associated with SARS-CoV-2 infection are milder in children compared with adults (3). Persons aged <21 years constitute 26% of the U.S. population (4), and this report describes characteristics of U.S. persons in that population who died in association with SARS-CoV-2 infection, as reported by public health jurisdictions. Among 121 SARS-CoV-2-associated deaths reported to CDC among persons aged <21 years in the United States during February 12-July 31, 2020, 63% occurred in males, 10% of decedents were aged <1 year, 20% were aged 1-9 years, 70% were aged 10-20 years, 45% were Hispanic persons, 29% were non-Hispanic Black (Black) persons, and 4% were non-Hispanic American Indian or Alaska Native (AI/AN) persons. Among these 121 decedents, 91 (75%) had an underlying medical condition,* 79 (65%) died after admission to a hospital, and 39 (32%) died at home or in the emergency department (ED). † These data show that nearly three quarters of SARS-CoV-2-associated deaths among infants, children, adolescents, and young adults have occurred in persons aged 10-20 years, with a disproportionate percentage among young adults aged 18-20 years and among Hispanics, Blacks, AI/ANs, and persons with underlying medical conditions. Careful monitoring of SARS-CoV-2 infections, deaths, and other severe outcomes among persons aged <21 years remains particularly important as schools reopen in the United States. Ongoing evaluation of effectiveness of prevention and control strategies will also be important to inform public health guidance for schools and parents and other caregivers., Competing Interests: All authors have completed and submitted the International Committee of Medical Journal Editors form for disclosure of potential conflicts of interest.

During January 1, 2020-May 18, 2020, approximately 1.3 million cases of coronavirus disease 2019 (COVID-19) and 83,000 COVID-19-associated deaths were reported in the United States (1). Understanding the demographic and clinical characteristics of decedents could inform medical and public health interventions focused on preventing COVID-19-associated mortality. This report describes decedents with laboratory-confirmed infection with SARS-CoV-2, the virus that causes COVID-19, using data from 1) the standardized CDC case-report form (case-based surveillance) (https://www.cdc.gov/coronavirus/2019-ncov/php/reporting-pui.html) and 2) supplementary data (supplemental surveillance), such as underlying medical conditions and location of death, obtained through collaboration between CDC and 16 public health jurisdictions (15 states and New York City).
