RESUMO
One of the recent advances in bariatric surgery is the use of magnetic devices. This research paper describes magnetic liver retraction in morbidly obese patients during bariatric surgery. A descriptive, prospective and observational study was carried out, analyzing 100 patients in whom magnetic retraction was used. Mean and SD body mass index was 46.1 ± 5.09 kg/m2. The magnetic system was successfully used for liver retraction in 95% of cases; in only 5% of cases was its use not possible due to hepatomegaly and severe hepatic steatosis. According to the results, magnetic liver retraction can be safe and used in bariatric surgery, regardless of body mass index and with a low percentage of complications.

BACKGROUND: Sleeve gastrectomy is one of the most popular bariatric surgeries. With the advent of new technologies, a reduced-port approach assisted by magnets for sleeve gastrectomy (RPSG-MA) has been developed. The aim of our study is to compare the short-term results of RPSG-MA vs conventional laparoscopic SG (CLSG). METHODS: A comparative study was performed. We compared two groups who underwent RPSG-MA (n=150) and CLSG (n=135) between January 2020 and January 2022. RESULTS: Both groups were similar in body mass index, age, sex, and type of comorbidities. The operative time was similar in both groups (RPSG-MA, 52.5 min vs CLSG, 52.9 min; p = 0.829). Length of hospital (1.07 days) stay was significantly shorter in the RPSG-MA group (p = 0.00) than in the CLSG group (1.51 days). There were no conversions to open surgery in any patient or any fatal event. Complications encountered were similar in both groups postoperative. There were minor adverse events directly related to the magnetic device in 3 cases, these being mild hepatic lacerations, resolved with hemostatic measures. CONCLUSION: The magnet-assisted reduced-port gastric sleeve compared to the conventional technique has proven to be safe, technically feasible and with multiple benefits.

INTRODUCTION: Magnetic devices have been successfully used in bariatric surgery. To the date, the only reported use of the magnet was for liver retraction. Our purpose in this study is to demonstrate the safety and viability of using a magnetic system in different steps in single port and reduced port bariatric surgery. METHODS: Prospective and observational study was performed. Patients older than 18 years, undergoing primary laparoscopic sleeve gastrectomy (SG), one-anastomosis gastric bypass (OAGB), and Roux-en-Y gastric bypass (RYGB) or revisional surgery by single-port or reduced-port approach between July 2020 and June 2021 were included. RESULTS: A total of 170 patients (mean BMI, 41.47kg/m2; mean age 36.92 yrs) completed laparoscopic bariatric surgery (54 single-port sleeve gastrectomy [SPSG], 16 reduced-port SG, 83 RYGB, 4 OAGB and 14 revision surgeries), using the magnetic surgical system in different steps of the surgery. Mean surgical time for SPSG and reduced-port SG was 65.52min and 59.36min respectively; and for RYGB 74.19min, OAGB 70.98min, and revisional surgeries 88.38min. As for intraoperative complications, 2.94% mild liver laceration without significant bleeding was reported. There were no 30-day mortalities and no major complications. CONCLUSION: Magnetic assistance in single-port and reduced-port bariatric surgery is an innovative technique. With this prospective study we attempt to demonstrate the safety profile and potential uses that may improve the implementation of new surgical approaches in bariatric surgery.

Roux-en-Y gastric bypass (RYGB) is one of the best procedures for the treatment of obesity and associated comorbidities. However, the percent of revisional procedures after a gastric bypass by weight regain has been increased, therefore several surgical options are available for the treatment of weight regain. In this case report, we combined a biliary limb distalization with endoscopic transoral outlet reduction (eTOR). The purpose of this case report is to expose the viability to perform combined procedures such as the distalization of the biliopancreatic limb plus eTOR increasing malabsorptive and restrictive components that would represent a secure and efficient weight loss in our patient. We could demonstrate the technical feasibility of the combination of both procedures to increase the restrictive and malabsorptive components at the same time with a low-risk range.

RESUMO
INTRODUCTION: In recent years there has been a significant growth in the percentage of patients with weight regain after Roux-en-Y gastric bypass (RYGB). Approximately 20% RYGB patients may experience weight regain 24 months after the intervention. PRESENTATION OF CASE: A 53 yr male patient who underwent RYGB in 2011 with an initial weight of 140 kg and BMI of 44.19 kg/m who consults in 2019 for a weight regain of 45.9%. Transoperative endoscopy assessment revealed a gastric pouch and gastrojejunal anastomosis with a diameter of 7 cm and 2.5 cm respectively. During the procedure we found a common channel of 725 cm, it is decided to shorten it through the distalization of the biliopancreatic limb. Afterward using the same laparoscopic ports to introduce the endoscope through jejunal cane to realize the APC therapy. He was discharged on the 2nd-day, without any complaint. DISCUSSION: The purpose of this case report is to expose the viability to perform a combined surgical technique such as the distalization of the biliopancreatic limb with endoscopic techniques of argon plasma coagulation (APC) via transjejunal in the same operative course. Using this combined technique we can increase hypoabsortive and restrictive components that would represent a secure and efficient weight loss in our patient. CONCLUSIONS: This innovative technique can represent a viable alternative that is secure and reproducible in revisional surgery for weight regain context.
RESUMO
La interacción entre el ambiente y la genética durante la evolución de la especie humana ha predispuesto al padecimiento de muchas enfermedades crónico-degenerativas comunes de nuestra sociedad occidentalizada. El genotipo Thrifty, producto de la adaptación del hombre paleolítico y neolítico al medio, se caracteriza por hiperinsulinemia sin inhibición de la gluconeogenesis, que, aunada al estilo de vida condiciona el desarrollo de enfermedades cardiovasculares (ECV). Múltiples hipótesis intentan explicar la elevada morbimortalidad por ECV en los diferentes grupos étnicos. Por ejemplo, las poblaciones afro-americanas presentan isoformas de proteínas desacoplantes relacionados con bajo gasto energético basal y metabolismo oxidativo de los ácidos grasos (AG) disminuido, así como una concentración elevada de Lipoproteína(a) y alta sensibilidad a la sal. La población asiática posee numerosos factores de riesgos cardiovasculares contrarrestados en parte por una dieta rica en PUFA´s ω-3. No obstante, los indio-asiáticos aún teniendo una dieta baja en AG saturados, presentan alta prevalencia de ECV, lo que se ha tratado de explicar por la expresión de un genotipo Thrifty. Las poblaciones hispánicas caracterizadas por su origen multirracial presentan alta incidencia de obesidad y diabetes relacionada a leptinorresistencia e insulinorresistencia, con hiperinsulinemia compensadora de duración variable- que aparentemente precede a la hipertensión arterial esencial. En poblaciones indígenas norteamericanas como los Pima se observa la prevalencia más alta de diabetes a nivel mundial, sugiriéndose una conexión con el gen de la PPP1R3, niveles de TNF-α elevados e IL-6, entre otros.
