Enhanced recovery after bariatric surgery: an Italian consensus statement.

BACKGROUND: Enhanced recovery after bariatric surgery (ERABS) is an approach developed to improve outcomes in obese surgical patients. Unfortunately, it is not evenly implemented in Italy. The Italian Society for the Surgery of Obesity and Metabolic Diseases and the Italian Society of Anesthesia, Analgesia, Resuscitation and Intensive Care joined in drafting an official statement on ERABS. METHODS: To assess the effectiveness and safety of ERABS and to develop evidence-based recommendations with regard to pre-, intra-, and post-operative care for obese patients undergoing ERABS, a 13-member expert task force of surgeons and anesthesiologists from Italian certified IFSO center of excellence in bariatric surgery was established and a review of English-language papers conducted. Oxford 2011 Levels of Evidence and U.S. Preventive Services Task Force Grade Definitions were used to grade the level of evidence and the strength of recommendations, respectively. The supporting evidence and recommendations were reviewed and discussed by the entire group at meetings to achieve a final consensus. RESULTS: Compared to the conventional approach, ERABS reduces the length of hospital stay and does not heighten the risk of major post-operative complications, re-operations, and hospital re-admissions, nor does it increase the overall surgical costs. A total of 25 recommendations were proposed, covering pre-operative evaluation and care (7 items), intra-operative management (1 item, 11 sub-items), and post-operative care and discharge (6 items). CONCLUSIONS: ERABS is an effective and safe approach. The recommendations allow the proper management of obese patients undergoing ERABS for a better outcome.

Changes of Taste, Smell and Eating Behavior in Patients Undergoing Bariatric Surgery: Associations with PROP Phenotypes and Polymorphisms in the Odorant-Binding Protein OBPIIa and CD36 Receptor Genes.

Bariatric surgery is the most effective long-term treatment for severe obesity and related comorbidities. Although patients who underwent bariatric surgery report changes of taste and smell perception, results from sensory studies are discrepant and limited. Here, we assessed taste and smell functions in 51 patients before, one month, and six months after undergoing bariatric surgery. We used taste strip tests to assess gustatory function (including sweetness, saltiness, sourness, umaminess, bitterness and oleic acid, a fatty stimulus), the "Sniffin' Sticks" test to assess olfactory identification and the 3-Factor Eating Questionnaire to assess eating behavior. We also explored associations between these phenotypes and flavor-related genes. Results showed an overall improvement in taste function (including increased sensitivity to oleic acid and the bitterness of 6-n-propylthiouracil (PROP)) and in olfactory function (which could be related to the increase in PROP and oleic acid sensitivity), an increase in cognitive restraint, and a decrease in disinhibition and hunger after bariatric surgery. These findings indicate that bariatric surgery can have a positive impact on olfactory and gustatory functions and eating behavior (with an important role of genetic factors, such PROP tasting), which in turn might contribute to the success of the intervention.

How can lean thinking improve ERAS program in bariatric surgery?

INTRODUCTION: Enhanced recovery after bariatric surgery protocol (ERABS) decreased length of hospital stay (LOS) without influencing clinical outcomes. ERABS improved logistics aspects in operating room (OR) with OR time savings. Lean management was used to reorganize OR logistics and to improve its efficiency. This study analyzed clinical and OR logistic aspects in ERABS protocols. METHODS: Retrospective analysis of prospectively maintained database of obese patients undergoing bariatric surgery from 2017 to 2019 was performed. Since September 2018, patients were treated with ERABS protocol (ERABS group). All patients treated with a standard protocol between January 2017 and September 2018 (control group) were compared to ERABS group. Preoperative (anthropometric data, surgical and medical history) and intraoperative (type of procedure) were analyzed in two groups. LOS was the primary outcomes parameter analyzed; complications, readmissions and reoperations within 30 days were the secondary outcomes. Logistic endpoints were evaluated in time saving and efficiency: surgical time, team work time and total anesthesia time. RESULTS: 471 patients underwent bariatric surgery: 239 patients (control group) compared to 232 patients (ERABS group). ERABS presented more previous surgical history rate (p = 0.04) compared to control group with difference of type of procedure performed (p < 0.001). Roux-en-Y gastric bypass was mainly procedure in both groups (61.1% in control group compared to 52.6% in ERABS groups). Mean LOS was shorter in ERABS (3.16 days) compared to control group (4.81 days) with no difference in clinical outcomes rate. All logistics endpoints showed a time savings in ERABS group compared to control group (surgical procedure, total anesthesia and team work time, p < 0.001). In multivariate analysis, LOS was associated to ERAS status (IRR 0.722; p < 0.0001), team work time (IRR 1.002; p = 0.002), surgical procedure time (IRR 1.002; p < 0.0001). ERAS status was not associated with complication neither readmission, but surgical procedure time was a factor associated with complication (IRR 1.011; p = 0.0008). CONCLUSION: This study confirmed that ERABS protocol is safe and a feasible alternative with improved LOS. OR reorganization and logistic efficiency achieved using lean management helped reduce all OR times and these are likely related to the improvement in LOS and complication.

Telemedicine Implementation on a Bariatric Outpatient Clinic During COVID-19 Pandemic in Italy: an Unexpected Hill-Start.

BACKGROUND: SARS-CoV2 outbreak has challenged NHS of many countries. Generalized restriction of movement, together with unprecedented pressure on Health System, disrupted routine care for non-COVID-19 patients. Telemedicine has been promoted to reduce the risk of infections and to offer medical assistance to the restricted population. This paper is aimed to evaluate the impact of tele-consulting technology in a single bariatric center. MATERIALS AND METHODS: Our outpatient clinic reorganized the service from on-site to long-distance video consultations. All patients received a satisfaction questionnaire. The main goals were to evaluate patient compliance and to assess patient satisfaction. RESULTS: Of the 33 booked patients who were offered a teleconsultation, 19 (57.6%) participated in the video-call. No significant differences were found between participants and non-participants in terms of age and gender ratio. Urban area residents were 57.9% of the participants versus 42.8% of the non-participants group. Of the participants, 52.6% completed the survey reporting levels of satisfaction ranging from high to very high. CONCLUSION: Telemedicine has been advocated as a useful tool to relieve pressure on the overwhelmed Health Systems during the COVID-19 pandemic. However, e-health technologies are not yet widely adopted. Our initial experience, also compared with national data relating to the digital divide, suggests that the absence of basic computer skills and the lack of confidence with video-call systems may be patient-specific barriers for the implementation of telemedicine. In this context, telemedicine implementation can run up against various patient-related barriers, and several challenges remain for e-health to be integrated into outpatient practice.
