Laparoscopic Sleeve Gastrectomy Feasible for Bariatric Revision Surgery

Bariatric revision surgery is associated with several complications that can be attributed to decreased quality of tissue and complexity of the surgery. A laparoscopic sleeve gastrectomy is a simple technique with potential advantages. Therefore, the results of this procedure were evaluated as a revisional option. Fifty-one patients underwent laparoscopic sleeve gastrectomy (LSG). Indications for the LSG were insufficient weight loss (34 patients, group 1) or vomiting (17 patients, group 2) following a laparoscopic adjustable gastric banding (LAGB) or vertical banded gastroplasty (VBG). Patient and procedure characteristics as well as outcome were collected prospectively. From October 2006 to June 2010, 51 patients with a failed prior bariatic procedure (VBG or LAGB) were converted to (L)SG. The conversion rate was zero. The median procedure time was 99 min (range 54–221) and hospital stay was 3 days (range 2–38). There was no mortality after 30 days. Complications included bleeding (six) and leakage of the staple line (seven). Mean follow-up was 13.8 (2–46) months. LSG as revision surgery for insufficient weight loss resulted in extra weight loss of 52.7%, and the overall extra weight loss was 49.3%. When LSG was performed because of vomiting, 82% was able to eat solid food at follow-up. Of the 65 pre-existent co-morbidities, 21 were resolved and 18 improved. LSG as a revision procedure is feasible. An additional weight loss and further resolution of co-morbidity seem achievable, however, at the cost of a high number of complications. Therefore, revision bariatric surgery should be limited to expert tertiary bariatric centers

The Value of Tracking Data on the Behavior of Patients Who Have Undergone Bariatric Surgery:Explorative Study

Background: To maintain the benefits of a bariatric procedure, patients have to change their lifestyle permanently. This happens within a context of coresponsibilities of health care professionals and their social support system. However, most interventions are focused on the patient as an individual. In this explorative pilot study, behavioral, contextual, and experiential data were gathered to obtain insight on coresponsibility. Objective: The aim of this study is to explore the use of trackers by patients who have undergone bariatric surgery in a data-enabled design approach. Methods: Behavioral and contextual data on the households of patients who have undergone bariatric surgery were explored using a smartphone with an interactive user interface (UI), weight scale, activity bracelet, smart socket, accelerometer motion sensor, and event button to find examples of opportunities for future interventions. Results: A total of 6 households were monitored. Approximately 483,000 data points were collected, and the participants engaged in 1483 conversations with the system. Examples were found using different combinations of data types, which provided the obesity team a better understanding of patient behaviors and their support system, such as a referral to a family coach instead of a dietician. Another finding regarding the partners was, for example, that the conversational UI system facilitated discussion about the support structure by asking for awareness. Conclusions: An intelligent system using a combination of quantitative data gathered by data tracking products in the home environment and qualitative data gathered by app-enhanced short conversations, as well as face-to-face interviews, is useful for an improved understanding of coresponsibilities in the households of patients who have undergone bariatric surgery. The examples found in this explorative study so far encourage research in this field.</p

European Hernia Society guidelines on management of rectus diastasis

Rectus diastasis; Hernia; GuidelinesDiástasis del recto; Hernia; PautasDiàstasi del recte; Hèrnia; PautesBackground The definition, classification and management of rectus diastasis (RD) are controversial in the literature and a variety of different surgical treatments have been described. This article reports on the European Hernia Society (EHS) Clinical Practice Guideline for RD. Method The Guideline group consisted of eight surgeons. The Grading of Recommendation, Assessment, Development and Evaluation (GRADE) approach and the Appraisal of Guidelines for Research and Evaluation (AGREE) instrument were used. A systematic literature search was done in November 2018 and updated in November 2019 and October 2020. Nine Key Questions (KQs) were formulated. Results Literature reporting on the definition, classification, symptoms, outcomes and treatments was limited in quality, leading to weak recommendations for the majority of the KQs. The main recommendation is to define RD as a separation between rectus muscles wider than 2 cm. A new classification system is suggested based on the width of muscle separation, postpregnancy status and whether or not there is a concomitant hernia. Impaired body image and core instability appear to be the most relevant symptoms. Physiotherapy may be considered before surgical management. It is suggested to use linea alba plication in patients without concomitant hernia and a mesh-based repair of RD with concomitant midline hernias. Conclusion RD should be defined as a separation of rectus muscles wider than 2 cm and a new classification system is suggested

Ekstrak Virgin Coconut Oil Sebagai Sumber Pangan Fungsional

Virgin Coconut Oil (VCO) merupakan salah satu jenis minyak nabati yang dapat bermanfaat dari aspek medis dan nutrisi karena dapat mencegah dan membantu mengobati penyakit tertentu serta dapat mempermudah proses pencernaan makanan dan penyerapan gizi. VCO dapat bertindak sebagai antioksidan dan antifotooksidan yang disebabkan oleh kandungan komponen minor (mikronutrien). Tujuan penelitian ini adalah mengekstrak komponen minor VCO menjadi produk untuk pangan fungsional yang mampu berperan sebagai antioksidan dan mengetahui peran VCO sebagai antiradikal bebas secara in vitro. Penelitian ini menggunakan metode eksperimental dengan 3 tahap yaitu: 1. Ekstraksi VCO menggunakan pelarut etanol dan metanol, 2. Pengujian penangkapan radikal bebas ekstrak VCO secara in vitro dengan metode 1,1-difenil-2-pikrilhidrazil (DPPH), 3. Identifikasi dan pengujian komponen kimia pada ekstrak VCO, identifikasi dan pengujian komponen minor pada ekstrak VCO dengan menggunakan High Performance Liquid Chromatography (HPLC). Hasil penelitian ini menunjukkan bahwa rendemen ekstrak VCO semakin tinggi dengan semakin tingginya persentase pelarut, ekstraksi dengan menggunakan etanol menghasilkan rendemen ekstrak yang lebih tinggi dibanding dengan menggunakan metanol. Aktivitas antioksidan dan kandungan total tokoferol dari ekstrak VCO semakin tinggi dengan semakin tingginya persentase pelarut yang digunakan. Salah satu senyawa tokoferol yang terdapat dalam VCO adalah -tokoferol. Berdasarkan analisa statistik menunjukkan bahwa etanol dan metanol menghasilkan sifat kimia ekstrak yang relatif sama, sehingga dapat direkomendasikan bahwa untuk mengekstraksi komponen minor dari VCO dapat menggunakan etanol karena di samping aman dari aspek kesehatan juga dapat menghasilkan rendemen ekstrak yang lebih tinggi

Lessons Learned from Telemonitoring in an Outpatient Bariatric Surgery Pathway-Secondary Outcomes of a Patient Preference Clinical Trial

Background: Remote monitoring is increasingly used to support postoperative care. This study aimed to describe the lessons learned from the use of telemonitoring in an outpatient bariatric surgery pathway. Materials and Methods: Patients were assigned based on their preference to an intervention cohort of same-day discharge after bariatric surgery. In total, 102 patients were monitored continuously for 7 days using a wearable monitoring device with a Continuous and Remote Early Warning Score–based notification protocol (CREWS). Outcome measures included missing data, course of postoperative heart and respiration rate, false positive notification and specificity analysis, and vital sign assessment during teleconsultation. Results: In 14.7% of the patients, data for heart rate was missing for &gt; 8 h. A day-night-rhythm of heart rate and respiration rate reappeared on average on postoperative day 2 with heart rate amplitude increasing after day 3. CREWS notification had a specificity of 98%. Of the 17 notifications, 70% was false positive. Half of them occurred between day 4 and 7 and were accompanied with surrounding reassuring values. Comparable postoperative complaints were encountered between patients with normal and deviated data. Conclusion: Telemonitoring after outpatient bariatric surgery is feasible. It supports clinical decisions, however does not replace nurse or physician care. Although infrequent, the false notification rate was high. We suggested additional contact may not be necessary when notifications occur after restoration of circadian rhythm or when surrounding reassuring vital signs are present. CREWS supports ruling out serious complications, what may reduce in-hospital re-evaluations. Following these lessons learned, increased patients’ comfort and decreased clinical workload could be expected. Trial Registration: ClinicalTrials.gov. Identifier: NCT04754893.

The Metabolic Health Index Identifies Patients That Will Benefit From Metabolic Surgery

Introduction: Metabolic syndrome is a modern world's major health hazard related to comorbidities like type 2 diabetes and cardiovascular disease. Bariatric surgery is well known to lower this health risk in patients with obesity. There is a need for an objective measure to assess the intended reduction in health hazard and indirectly the eligibility for bariatric surgery. The Metabolic Health Index (MHI) quantitatively summarizes the cumulative impact of the metabolic syndrome on health status on a scale from 1 to 6. This study describes the use of the MHI as a supportive tool in the decision for and outcome assessment of bariatric surgery. Methods: The general usability of the MHI was tested by extending its application to patient data of five other bariatric centers in the Netherlands. Retrospective laboratory and national bariatric quality registry data of 11,501 patients were collected. Results: The quantification of (improvement in) metabolic health burden as measured by the MHI was independent of the dataset that was used to derive the MHI model. Patients with MHI &gt; 2.8 prior to surgery improved significantly more in MHI 12 mo after surgery compared to patients with MHI ≤ 2.8 (1.1 compared to 0.4 MHI points, respectively; P &lt; 0.001). Conclusions: The MHI is robust between centers and is suitable for general use in clinical decision-making. As changes in MHI over time reflect metabolic health alterations, it is suitable as an outcome measure of surgery. An MHI cut-off value of 2.8 helps to predict the likelihood of significant improvement after surgery, independent of body mass index and known metabolic comorbidities.</p
