- Adjustable Gastric Banding Conversion to One Anastomosis Gastric Bypass: Data Analysis of a Multicenter DatabasePublication . Pujol-Rafols, J; Uyanik, O; Curbelo-Peña, Y; Abbas, AA; Devriendt, S; Guerra, A; Herrera, MF; Himpens, J; Pardina, E; Pouwels, S; Ramos, A; Ribeiro, RJ; Safadi, B; Sanchez-Aguilar, H; De Vries, CE; Van Wagensveld, BIntroduction: One anastomosis gastric bypass (OAGB) has been proposed as a rescue technique for laparoscopic adjustable gastric banding (LAGB) poor responders. Aim: We sought to analyze, complications, mortality, and medium-term weight loss results after LAGB conversion to OAGB. Methods: Data analysis of an international multicenter database. Results: One hundred eighty-nine LAGB-to-OAGB operations were retrospectively analyzed. Eighty-seven (46.0%) were converted in one stage. Patients operated on in two stages had a higher preoperative body mass index (BMI) (37.9 vs. 41.3 kg/m2, p = 0.0007) and were more likely to have encountered technical complications, such as slippage or erosions (36% vs. 78%, p < 0.0001). Postoperative complications occurred in 4.8% of the patients (4.6% and 4.9% in the one-stage and the two-stage group, respectively). Leak rate, bleeding episodes, and mortality were 2.6%, 0.5%, and 0.5%, respectively. The final BMI was 30.2 at a mean follow-up of 31.4 months. Follow-up at 1, 3, and 5 years was 100%, 88%, and 70%, respectively. Conclusion: Conversion from LAGB to OAGB is safe and effective. The one-stage approach appears to be the preferred option in non-complicate cases, while the two-step approach is mostly done for more complicated cases.
- 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.
- Conversion of Adjustable Gastric Banding to Roux-en-Y Gastric Bypass in One or Two Steps: What Is the Best Approach? Analysis of a Multicenter Database Concerning 832 PatientsPublication . Pujol-Rafols, J; Al Abbas, AI; Devriendt, S; Guerra, A; Herrera, MF; Himpens, J; Pardina, E; Pouwels, S; Ramos, A; Ribeiro, RJ; Safadi, B; Sanchez-Aguilar, H; de Vries, C; Van Wagensveld, BBackground: Roux-en-Y gastric bypass (RYGB) is often the preferred conversion procedure for laparoscopic adjustable gastric banding (LAGB) poor responders. However, there is controversy whether it is better to convert in one or two stages. This study aims to compare the outcomes of one and two-stage conversions of LAGB to RYGB. Methods: Retrospective review of a multicenter prospectively collected database. Data on conversion in one and two stages was compared. Results: Eight hundred thirty-two patients underwent LAGB conversion to RYGB in seven specialized bariatric centers. Six hundred seventy-three (81%) were converted in one-stage. Patients in the two-stage group were more likely to have experienced technical complications, such as slippage or erosions (86% vs. 37%, p = 0.0001) and to have had a higher body mass index (BMI) (41.6 vs. 39.9 Kg/m2, p = 0.005). There were no differences in postoperative complications and mortality rates between the one-stage and two-stage groups (13.5% vs. 10.8%, and 0.7% vs. 0.0% respectively, p = ns). Mean final BMI and %total weight loss (%TWL) for the one-stage and the two-stage groups were 31.6 vs. 32.4 Kg/m2 (p = ns) and 30.4 vs. 26.8 (p = 0.017) after a mean follow-up of 33 months. Follow-up at 1, 3, and 5 years was 98%, 75%, and 54%, respectively. Conclusions: One-stage conversion of LAGB to RYGB is safe and effective. Two-stage conversion carries low morbidity and mortality in the case of band slippage, erosion, or higher BMI patients. These findings suggest the importance of patient selection when choosing the appropriate conversion approach
- 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.
- Nutritional and Lifestyle Behaviors Reported Following One Anastomosis Gastric Bypass Based on a Multicenter StudyPublication . Sherf-Dagan, S; Biton, R; Ribeiro, R; Kessler, Y; Raziel, A; Rossoni, C; Kais, H; Bragança, R; Santos, Z; Goitein, D; Viveiros, O; Graham, Y; Mahawar, K; Sakran, N; Ben-Porat, TThis study aimed to describe nutritional and lifestyle parameters following one-anastomosis gastric bypass (OAGB). A multicenter study among OAGB patients across Israel (n = 277) and Portugal (n = 111) was performed. Patients were approached according to the time elapsed since surgery. An online survey with information regarding demographics, anthropometrics, and nutritional and lifestyle aspects was administered in both countries simultaneously. Respondents from Israel (pre-surgery age of 41.6 ± 11.0 years, 75.8% females) and Portugal (pre-surgery age of 45.6 ± 12.3 years, 79.3% females) reported changes in their appetite (≤94.0% and ≤94.6%), changes in their taste (≤51.0 and ≤51.4%), and intolerance to specific foods (i.e., red meat, pasta, bread, and rice). Bariatric surgery-related eating recommendations were generally followed well, but a trend toward lower adherence was evident in groups with longer time elapsed since surgery in both countries. Most respondents from Israel and Portugal reported participation in follow-up meetings with a surgeon (≤94.0% and 100%) and a dietitian (≤92.6% and ≤100%), while far fewer reported participation in any follow-up meeting with a psychologist/social worker (≤37.9% and ≤56.1%). Patients following OAGB might experience changes in appetite, taste, and intolerance to specific foods. Adherence to bariatric surgery-related eating recommendations is not always satisfying, especially in the longer term post-surgery.
- Outcomes of Long Pouch Gastric Bypass (LPGB): 4-Year Experience in Primary and Revision CasesPublication . Ribeiro, R; Pouwels, S; Parmar, C; Pereira, J; Manaças, L; Guerra, AC; Borges, N; Ribeiro, J; Viveiros, OBackground: One of the most important complications of the one anastomosis gastric bypass (OAGB) is enterobilio acid reflux (EBAR). We report the concept of the long pouch Roux-en-Y gastric bypass (LPRYGB) meaning a Roux-en-Y with a long pouch and a 100-cm alimentary limb to avoid EBAR, with a long biliopancreatic limb to increase metabolic effects. Methods: A total of 300 LPRYGB cases in a 4-year period, with a 90% follow-up rate, were analysed. Anthropometric, technical feasibility, morbidity, weight loss and comorbidity outcomes were analysed. Results: The percentage total weight loss (%TWL) was 30.5% at 4 years of follow-up (32.3% in primary and 28.3% in revisions). Six intra-operative (2%) and 28 postoperative complications (9.3%) were seen. Out of this 28 complications, 11 (3.6%) were late complications. Reoperations were performed in 15 patients (5.0%). Clinically relevant EBAR was present in 3 cases only (1%) 4 years after the operation. Conclusions: The LPRYGB combines the main advantages of the OAGB (light restriction and moderate malabsorption) with the anti-reflux effect from the Roux-en-Y diversion.
- Patient Selection in One Anastomosis/Mini Gastric Bypass—an Expert Modified Delphi ConsensusPublication . Kermansaravi, M; Parmar, C; Chiappetta, S; Shahabi, S; Abbass, A; Abbas, SI; Abouzeid, M; Antozzi, L; Asghar, ST; Bashir, A; Bhandari, M; Billy, H; Caina, D; Campos, FJ; Carbajo, MA; Chevallier, JM; Jazi, AH; de Gordejuela, AG; Haddad, A; ElFawal, MH; Himpens, J; Inam, A; Kassir, R; Kasama, K; Khan, A; Kow, L; Kular, KS; Lakdawala, M; Layani, LA; Lee, WJ; Luque-de-León, E; Loi, K; Mahawar, K; Mahdy, T; Musella, M; Nimeri, A; González, JC; Pazouki, A; Poghosyan, T; Prager, G; Prasad, A; Ramos, AC; Rheinwalt, K; Ribeiro, R; Ruiz-Úcar, E; Rutledge, R; Shabbir, A; Shikora, S; Singhal, R; Taha, O; Talebpour, M; Verboonen, JS; Wang, C; Weiner, R; Yang, W; Vilallonga, R; De Luca, MPurpose: One anastomosis/mini gastric bypass (OAGB/MGB) is up to date the third most performed obesity and metabolic procedure worldwide, which recently has been endorsed by ASMBS. The main criticisms are the risk of bile reflux, esophageal cancer, and malnutrition. Although IFSO has recognized this procedure, guidance is needed regarding selection criteria. To give clinicians a daily support in performing the right patient selection in OAGB/MGB, the aim of this paper is to generate clinical guidelines based on an expert modified Delphi consensus. Methods: A committee of 57 recognized bariatric surgeons from 24 countries created 69 statements. Modified Delphi consensus voting was performed in two rounds. An agreement/disagreement among ≥ 70.0% of the experts was considered to indicate a consensus. Results: Consensus was achieved for 56 statements. Remarkably, ≥ 90.0% of the experts felt that OAGB/MGB is an acceptable and suitable option "in patients with Body mass index (BMI) > 70, BMI > 60, BMI > 50 kg/m2 as a one-stage procedure," "as the second stage of a two-stage bariatric surgery after Sleeve Gastrectomy for BMI > 50 kg/m2 (instead of BPD/DS)," and "in patients with weight regain after restrictive procedures. No consensus was reached on the statement that OAGB/MGB is a suitable option in case of resistant Helicobacter pylori. This is likely as there is a concern that this procedure is associated with reflux and its related long-term complications including risk of cancer in the esophagus or stomach. Also no consensus reached on OAGB/MGB as conversional surgery in patients with GERD after restrictive procedures. Consensus for disagreement was predominantly achieved "in case of intestinal metaplasia of the stomach" (74.55%), "in patients with severe Gastro Esophageal Reflux Disease (GERD)(C,D)" (75.44%), "in patients with Barrett's metaplasia" (89.29%), and "in documented insulinoma" (89.47%). Conclusion: Patient selection in OAGB/MGB is still a point of discussion among experts. There was consensus that OAGB/MGB is a suitable option in elderly patients, patients with low BMI (30-35 kg/m2) with associated metabolic problems, and patients with BMIs more than 50 kg/m2 as one-stage procedure. OAGB/MGB can also be a safe procedure in vegetarian and vegan patients. Although OAGB/MGB can be a suitable procedure in patients with large hiatal hernia with concurrent hiatal hernia, it should not be offered to patients with grade C or D esophagitis or Barrett's metaplasia.
- Peri-operative management of a pregnant patient with hereditary angioedema submitted to a cesarean-section: case reportPublication . Nunes-Estevens, TM; Serrano, A; Amaro, S; Ribeiro, JHereditary angioedema is an autosomal dominant disorder, presenting as sudden and recurring episodes of variable severity of subcutaneous and mucosa edema that may occur spontaneously or in response to triggers. There are three knwon types of hereditary angioedema. The disorder is caused by decrease in the plasma level or change in the functional capacity of C1 inhibitor, with increase in bradykinin and in vascular permeability, and consequent edema. Several measures are required in the perioperative period in order to avoid an acute attack. Prophylaxis should be carried out throughout pregnancy before any surgical procedure, before dental procedures, upon airway handling, on patients with previous episodes of angioedema, and when there are significant changes in volemia. The literature is scarce in regard to the association between hereditary angioedema and pregnancy. We describe a successful case of a pregnant patient with type I hereditary angioedema submitted to a C-section.
- Trauma Associado às Touradas à Corda nos Açores: Um Estudo TransversalPublication . Vieira, B; Taranu, V; Vieira, A; Soares, D; Soares, A; Silva, A; Galvão, D; Bagnari, I; Melo, D; Pimentel, F; Sousa, J; Martins, L; Pinheiro, L; Vargas, M; Reis, Ó; Valente, S; Bettencourt, R; Oliveira, T; Mora, AIntroduction: The aim of the study was to describe trauma injuries associated with rope bullfights in the Azores, Portugal, regarding the cause of the incident, trauma mechanism, most affected anatomical areas, and injury severity. Methods: Two-year cross-sectional study in the local hospital with prospective data collection. Patients who were consecutively admitted to the local hospital’s emergency department with trauma injuries from the bull’s direct impact or from falls either during the bull’s escape or when handling the rope, were included. Data on general demographics, lesion characteristics, treatments, need for hospitalization and mortality were collected. Results: Fifty-six incidents and 80 trauma injuries were identified. The main cause of trauma was the bull’s direct impact (37; 66.07%) and the mechanism of injury was blunt trauma in all patients (100%; 56). Head and neck injuries (27; 33.75%) were the most common. The median Injury Severity Score at the emergency department admission was 4. Major trauma was noted in five patients (8.92%). Ten patients (17.85%) needed hospitalization with a median hospital stay of seven days. Three of the 10 hospitalized patients (30%) were previously admitted to the intensive care unit. Surgery was performed in six patients (10.71%). Conclusion: The main cause of trauma was the bull’s direct impact, and the mechanism of injury was blunt trauma. The most affected anatomical areas were the head and neck. These findings are a wake-up call to the impact of these events regarding the economic costs they entail, the costs for the health of the local population, the safety measures currently implemented and the availability of the necessary means to treat these patients.
