- Best practice approach for redo-surgeries after sleeve gastrectomy, an expert's modified Delphi consensusPublication . Kermansaravi, M; Parmar, C; Chiappetta, S; Shikora, S; Aminian, A; Abbas, SI; Angrisani, L; Bashir, A; Behrens, E; Bhandari, M; Clapp, B; Cohen, R; Dargent, Jerome; Dilemans, Bruno; De Luca, Maurizio; Haddad, Ashraf; Gawdat, Khaled; Elfawal, Mohamed Hayssam; Himpens, Jaques; Huang, Chih-Kun; Husain, Farah; Kasama, Kazunori; Kassir, Radwan; Khan, Amir; Kow, Lilian; Kroh, Matthew; Lakdawala, Muffazal; Lopez Corvala, JA; Miller, Karl; Musella, M; Nimeri, A; Noel, P; Palermo, M; Poggi, L; Poghosyan, T; Prager, G; Prasad, A; Alqahtani, A; Rheinwalt, K; Ribeiro, R; Shabbir, A; Torres, A; Villalonga, R; Wang, C; Mahawar, K; Zundel, NBackground: 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.
- C-reactive Protein Variation and Its Usefulness in the Prognostication and Monitoring of Patients With Pneumococcal PneumoniaPublication . Gomes, A; Ribeiro, R; Froes, F; Mergulhão, P; Gonçalves Pereira, JBackground and objective Community-acquired pneumonia (CAP) is a prevalent and life-threatening infection that causes significant morbidity and mortality. Biomarkers, such as C-reactive protein (CRP), can help to diagnose, monitor, and prognose patients with this condition. This study aimed to analyze the disease course, the CRP peak concentration, its relationship with prognosis, and its variation in hospitalized patients with pneumococcal CAP. Methodology This study included 797 patients diagnosed with pneumococcal CAP and admitted over four years to four different Portuguese hospitals, either to the ICU or the general ward. Results Although CRP peak concentration was not a good predictor of overall hospital mortality, higher peak concentration in older patients (>60 years) was associated with a dismal hospital prognosis. In contrast, younger patients who survived hospital discharge had a non-significant higher peak CRP concentration. A faster time until CRP decreased to at least half of its peak value also correlated with favorable outcomes after adjusting for age and bacteremia [failure to achieve a 50% decrease was associated with an adjusted hazard ratio (HR) for hospital mortality of 6.45; 95% confidence interval (CI): 4.30-9.69]. Conclusions Based on our findings, CRP may be a useful biomarker in the hospital setting for diagnosing and monitoring patients with pneumococcal CAP. Clinicians must be aware of its unique properties, clinical applications, and varying behaviors according to patient age groups.

- Conversion from Roux-En-Y Gastric Bypass to Sadi-S, with a Gastro-Gastric Jejunal Bridge as a Treatment of Obesity Recidivism: Case ReportPublication . Dib, V; Madalosso, C; Scortegagna, G; Ribeiro, RThere is a considerable weight regain after the Roux-en-Y gastric bypass (RYGB) surgery. Surgical conversion to more powerful metabolic techniques, like one anastomosis duodenal switch with sleeve gastrectomy (SADI-S), can be effective in this scenario, but surgically challenging. This case report aims to demonstrate technical modifications that simplifies the conversion of Roux-en-Y gastric bypass to SADI-S, in one stage. Female patient submitted to laparoscopic RYGB 10 years before with nadir of 29,47Kg/m². In the last 4 years, she had regained weight, reaching a body mass index of 46,48Kg/m². Surgical conversion was done laparoscopically, preserving the gastrojejunal anastomosis from the previous RYGB and the proximal 8cm of jejunal alimentary limb, which was transected at this level and used as a bridge between gastric pouch and antrum. Previously, the fundus, gastric body and part of the antrum were removed. The remaining alimentary limb, the gallbladder and the candy cane was removed. This was a single stage procedure, without complications. The interposition of the proximal alimentary limb of gastric bypass, between gastric pouch and antrum, has shown to be safe and feasible in RYGB conversion to SADI-S. The removal of the remnant alimentary limb makes the procedure shorter.

- Enhanced Recovery After Surgery (ERAS) protocol in bariatric and metabolic surgery (BMS)-analysis of practices in nutritional aspects from five continentsPublication . Rossoni, C; Oliveira Magro, D; Santos, ZC; Cambi, MP; Patias, L; Bragança, R; Pellizzaro, D; Parmar, C; Ribeiro, RThis study aims to understand the prevalent practices on the nutritional aspects of the enhanced recovery after surgery (ERAS) protocol based on the knowledge and practice of surgeons, nutritionists, and anesthesiologists who work in the bariatric and metabolic surgery (BMS) units worldwide. This cross-sectional study enrolled BMS unit professionals from five continents-Africa, America, Asia, Europe, and Oceania. An electronic questionnaire developed by the researchers was provided to evaluate practices about the three nutritional aspects of ERAS protocol in BMS (Thorel et al. 2016): preoperative fasting, carbohydrate loading, and early postoperative nutrition. Only surgeons, nutritionists, and anesthesiologists were invited to participate. One hundred twenty-five professionals answered the questionnaires: 50.4% from America and 39.2% from Europe. The profile of participating professionals was bariatric surgeons 70.2%, nutritionists 26.4%, and anesthesiologists 3.3%. Approximately 47.9% of professionals work in private services, for about 11 to 20 years (48.7%). In all continents, a large majority were aware of the protocol. Professionals from the African continent reported having implemented the ERAS bariatric protocol 4.0 ± 0 years ago. It is worth mentioning that professionals from the five continents implemented the ERAS protocol based on the published literature (p = 0.012). About preoperative fasting abbreviation protocol, a significant difference was found between continents and consequently between services (p = 0.000). There is no uniformity in the conduct of shortening of fasting in the preoperative period and the immediate postoperative period. Early postoperative (PO) period protein supplementation is not performed in a standard fashion in all units globally. ERAS principles and practices are partial and insufficiently implemented on the five continents despite the prevalent knowledge of professionals based on evidence. Moreover, there is no uniformity in fasting, immediate postoperative diet, and early protein supplementation practices globally.
- Evaluation of the Efficacy of Single Anastomosis Sleeve Ileal (SASI) Bypass for Patients with Morbid Obesity: a Multicenter StudyPublication . Mahdy, T; Emile, SH; Madyan, A; Schou, C; Alwahidi, A; Ribeiro, R; Sewefy, A; Büsing, M; Al-Haifi, M; Salih, E; Shikora, SBackground: Single anastomosis sleeve ileal (SASI) bypass is a newly introduced bariatric and metabolic procedure. The present multicenter study aimed to evaluate the efficacy of the SASI bypass in the treatment of patients with morbid obesity and the metabolic syndrome. Methods: This is a retrospective, seven-country, multicenter study on patients with morbid obesity who underwent the SASI bypass. Data regarding patients' demographics, body mass index (BMI), percentage of total weight loss (%TWL), percentage of excess weight loss (%EWL), and improvement in comorbidities at 12 months postoperatively and postoperative complications were collected. Results: Among 605 patients who underwent the SASI, 54 were excluded and 551 (390; 70.8% female) were included. At 12 months after the SASI, a significant decrease in the BMI was observed (43.2 ± 12.5 to 31.2 ± 9.7 kg/m2; p < 0.0001). The %TWL was 27.4 ± 13.4 and the %EWL was 63.9 ± 29.5. Among the 279 patients with type 2 diabetes mellitus (T2DM), complete remission was recorded in 234 (83.9%) patients and partial improvement in 43 (15.4%) patients. Eighty-six (36.1%) patients with hypertension, 104 (65%) patients with hyperlipidemia, 37 (57.8%) patients with sleep apnea, and 70 (92.1%) patients with GERD achieved remission. Fifty-six (10.1%) complications and 2 (0.3%) mortalities were recorded. Most complications were minor. All patients had 12 months follow-up. Conclusions: The SASI bypass is an effective bariatric and metabolic surgery that achieved satisfactory weight loss and improvement in medical comorbidities, including T2DM, hypertension, sleep apnea, and GERD, with a low complication rate.
- Metabolic and Bariatric Surgery in Patients with Obesity Class V (BMI > 60 kg/m2): a Modified Delphi StudyPublication . Ponce de Leon-Ballesteros, G; Pouwels, S; Romero-Velez, G; Aminian, A; Angrisani, L; Bhandari, M; Brown, W; Copaescu, C; De Luca, M; Fobi, M; Ghanem, OM; Hasenberg, T; Herrera, MF; Herrera-Kok, JH; Himpens, J; Kow, L; Kroh, M; Kurian, M; Musella, M; Narwaria, M; Noel, P; Pantoja, JP; Ponce, J; Prager, G; Ramos, A; Ribeiro, R; Ruiz-Ucar, E; Salminen, P; Shikora, S; Small, P; Stier, C; Taha, S; Taskin, EH; Torres, A; Vaz, C; Vilallonga, R; Verboonen, S; Zerrweck, C; Zundel, N; Parmar, CBackground: Metabolic and bariatric surgery (MBS) is the preferred method to achieve significant weight loss in patients with Obesity Class V (BMI > 60 kg/m2). However, there is no consensus regarding the best procedure(s) for this population. Additionally, these patients will likely have a higher risk of complications and mortality. The aim of this study was to achieve a consensus among a global panel of expert bariatric surgeons using a modified Delphi methodology. Methods: A total of 36 recognized opinion-makers and highly experienced metabolic and bariatric surgeons participated in the present Delphi consensus. 81 statements on preoperative management, selection of the procedure, perioperative management, weight loss parameters, follow-up, and metabolic outcomes were voted on in two rounds. A consensus was considered reached when an agreement of ≥ 70% of experts' votes was achieved. Results: A total of 54 out of 81 statements reached consensus. Remarkably, more than 90% of the experts agreed that patients should be notified of the greater risk of complications, the possibility of modifications to the surgical procedure, and the early start of chemical thromboprophylaxis. Regarding the choice of the procedure, SADI-S, RYGB, and OAGB were the top 3 preferred operations. However, no consensus was reached on the limb length in these operations. Conclusion: This study represents the first attempt to reach consensus on the choice of procedures as well as perioperative management in patients with obesity class V. Although overall consensus was reached in different areas, more research is needed to better serve this high-risk population.
