Purpose: To compare the satisfaction levels about the surgery and anesthesia management, and to analyze the postoperative outcomes of patients undergoing Gastric Bypass and Sleeve Gastroplasty surgeries in a private hospital in Sao Luís-MA. Methods: The sample consisted of patients undergoing Bypass and Sleeve bariatric surgeries from August 2018 to August 2019, who were in the range of 18 and 70 years old and had not used drugs or presented cardiac arrhythmias, dilated cardiomyopathy, and conduction disorder heart. Data were collected from the evaluation forms and recorded in a form with closed questions. Results: Most patients were female (Bypass 56% and Sleeve 67.4%) and aged between 30 and 39 years old (Bypass 32% and Sleeve 55.8%). Information (Bypass 92% and Sleeve 86.1%) was the highest satisfaction index found. Sleepiness in the immediate postoperative period (Bypass 92% and Sleeve 93%) was the main side effect. There were no postoperative complications in patients between the two types of surgery. Conclusions: Patients submitted to Bypass and Sleeve were completely satisfied with the perioperative management. There was no statistically significant difference when comparing adverse effects between the techniques.(AU)

Purpose To evaluate the analgesic effect of esmolol in patients submitted to laparoscopic gastroplasty. Methods Forty patients aged between 18 and 50 years with American Society of Anesthesiologists (ASA) physical status scores of II and III who underwent gastric bypass were allocated to two groups. Group 1 patients received a 0.5-mg/kg bolus of esmolol in 30 mL of saline before induction of anesthesia, followed by an infusion at 15 µg/kg/min until the end of surgery. Group 2 patients received 30 mL of saline as a bolus and then an infusion of saline. Anesthesia included fentanyl (3 µg/kg), propofol (2-4 mg/kg), rocuronium (0.6 mg/kg), and 2% sevoflurane, with remifentanil if necessary. The following parameters were evaluated: pain intensity over 24h, remifentanil consumption, the first analgesic request, morphine consumption, and side effects. Results Pain intensity was lower in the esmolol group except at T0 (after extubation) and 12h postoperatively. Remifentanil supplementation, recovery time, and postoperative morphine supplementation were lower in the esmolol group. No differences in the time to the first analgesic request or side effects were found between the groups. Conclusion Intraoperative esmolol promotes reductions in pain intensity and the need for analgesic supplementation without adverse effects, thus representing an effective drug for multimodal analgesia in gastroplasty.(AU)

Purpose. To analyze, in aged obese patients, the weight loss, comorbidity control, and safety postoperative complications of bariatric surgery by Roux-en-Y gastric bypass technique.. Methods. Twenty-seven patients who underwent laparoscopic weight-reducing gastroplasty with Roux-en-Y gastric bypass to treat obesity were included. All patients were ≥ 60 years old at the time of surgery. The Wilcoxon test was used for statistical analysis, and a p-value ≤0.05it was considered significant.. Results. Ten (90.9%) patients with dyslipidemia were cured (p < 0.001). Nine (81.8%) patients with type 2 diabetes mellitus had total improvement and 2 (18.2%) had partial improvement (p = 0.003). In 23 patients with systemic arterial hypertension, 9 (39.1%) achieved total improvement and 14 (60.9%) partial improvement (p = 0.140). Five (71.4%) patients with obstructive sleep apnea syndrome were cured (p = <0.001). For other comorbidities, no partial improvement or cure was shown.. Conclusions. Roux-en-Y gastric bypass surgery in obese elderly patients can be performed safely and with low morbidity and mortality rates. The benefits of weight loss and reduced comorbidities are promising and like those of the younger population.(AU)

Purpose: To evaluate the serum variations of Interleukins (Il) and CPR of abdominoplasties in post-bariatric patients and, to equate the homeostasis (HOMA) from the variations of glycemia and insulin to evolute the metabolic modifications.Methods: Fourteen women were submitted to abdominoplasties with weight loss after a gastroplasty. Levels of IL4, IL6, IL10, CRP, glycemia and insulin were obtained during the pre-operative, trans-operative, 24 hours post, 7th and 14th postoperative days.Results: The IL4 was higher at 24 hours post-surgery, and after a moderate decrease, it remained high until the 14th day. The IL6 and CRP had an expressive increase during the trans-operative period. The CRP remained high, and the IL6 decreased on the 7th and 14th days. The IL10 increased during the transoperative period, and it posteriorly decreased to lower levels in comparison to the pre-operative period. The already increased glycemia during the pre-operative period was even higher during the trans-operative and then, returned to preliminary values on the 7th and 14th days after surgery. The HOMA accompanied the insulin. Conclusion: The inflammatory and glycemic serum levels decrease after abdominiplasty in obese post-bariatric patients.(AU)

PURPOSE: Sleeve gastrectomy (SG) removes substantial part of the gastric mucosa, which produces ghrelin. This reduction is expected to force other organs, such as the duodenum, to compensate by increasing the number of ghrelin-producing cells. The purpose of this study was to evaluate whether this response occurs. METHODS: Twelve adult male, Wistar rats underwent SG and were reoperated 30 or 60 days after the initial surgery. During the second surgery, a segment of the duodenum was resected to count ghrelin cells using immunohistochemistry. In six animals, SG was not performed, and the duodenal segment served as a control for ghrelin cell counts. The ghrelin cell index (GCI), which is the number of ghrelin cells divided by the number of villi in each segment, was measured and used in statistical analysis by one-way analysis of variance (ANOVA). RESULTS:There were increases in the absolute numbers of cells 30 and 60 days after SG, but statistical analysis by ANOVA showed no significant difference between the groups. CONCLUSION: A compensatory increase in the number of duodenal immunopositive ghrelin cells did not occur as a response to sleeve gastrectomy.(AU)


OBJETIVO: A gastrectomia vertical (GV) remove a maior parte das células produtoras de grelina. Esta redução poderia induzir o duodeno a produzir mais células de grelina de forma compensadora. O objetivo deste trabalho foi estudar se esta compensação ocorre. MÉTODOS: Doze ratos Wistar, machos, foram submetidos à GV e reoperados 30 e 60 dias depois (grupos 30D e 60D) quando um segmento de duodeno foi ressecado para contagem de células de grelina por imunoistoquímica. Em seis animais não foi realizada a GV e um segmento de duodeno foi ressecado para contagem de células de grelina por imunoistoquímica (grupo controle). O índice de células de grelina (ICG), que é o número de células imunopositivas para grelina dividido pelo número de vilosidades do segmento foi calculado e utilizado na análise estatística pelo teste da análise de variância (ANOVA). RESULTADOS: Houve aumento no número absoluto de células 30 e 60 dias depois da gastrectomia vertical, mas a análise estatística por ANOVA não mostrou diferenças significantes entre os grupos. CONCLUSÃO: Não foi observado aumento compensatório no número de células de grelina duodenais após a gastroplastia vertical.(AU)

PURPOSE: To evaluate the incidence of fistula and stenosis of the cervical esophagogastric anastomosis with invagination of the proximal esophageal stump into the stomach after subtotal esophagectomy. METHODS: We studied 54 patients who underwent subtotal esophagectomy, 45 (83.3%) patients with carcinoma and nine (16.6%) with advanced megaesophagus. In all cases the cervical esophagogastric anastomosis was performed with the invagination of the proximal esophageal stump inside the stomach. RESULTS: Three (5.5%) patients had a fistula at the esophagogastric anastomosis, two of whom with minimal leakage of air or saliva and with mild clinical repercussion; the third had a low output fistula that drained into the pleural space, and this patient developed empyema that showed good progress with drainage. Fibrotic stenosis of anastomosis occurred in thirteen (24%) subjects and was treated successfully with endoscopic dilatation. CONCLUSION: Cervical esophagogastric anastomosis with invagination of the proximal esophageal stump into the stomach tube presented a low rate of esophagogastric fistula and stenosis, thus becoming an attractive option for the reconstruction of alimentary transit after subtotal esophagectomy.(AU)


OBJETIVO: Avaliar a incidência de fístula e estenose da anastomose esofagogástrica cervical com invaginação do coto esofágico proximal no interior do estômago após esofagectomia subtotal. MÉTODOS: Foram estudados 54 pacientes submetidos à esofagectomia subtotal, 45 (83,3%) com carcinoma e nove (16,6%) com megaesôfago chagásico avançado. Em todos os casos, a anastomose esofagogástrica cervical foi realizada com invaginação do coto esofágico proximal no interior do estômago. RESULTADOS: Três (5,5%) pacientes apresentaram fístula, dois deles com saída mínima de ar e saliva pela incisão cervical que evoluíram com rápida cicatrização; o terceiro apresentou fístula de pequeno débito que drenou para o espaço pleural causando empiema que teve boa evolução após drenagem. Treze (24%) doentes apresentaram estenose fibrótica e foram tratados com sucesso com dilatação endoscópica. CONCLUSÃO: A anastomose esofagogástrica cervical com invaginação do coto esofágico proximal no interior do estômago apresentou baixa incidência de fístula e estenose tornando-se opção atraente para a reconstrução do trânsito alimentar após esofagectomia subtotal.(AU)

PURPOSE: To evaluate a technique to remove the thoracic esophagus without thoracotomy and two methods for thoracic esophageal replacement in dogs. METHODS: 27 ex-vivo dogs were divided into three groups in order to evaluate: G1 - total thoracic esophagectomy by the everting stripping method; G2 - total thoracic esophagectomy and esophageal substitution using the whole stomach; G3 - total thoracic esophagectomy and esophageal substitution using fundus rotation gastroplasty. After esophageal resection in G1, the integrity of the intrathoracic route was evaluated by endoscopy and tested with 1 percent methylene blue solution. RESULTS: Visceral pleural rupture was observed in all animals. However, this intrathoracic route made it possible to bring both esophagus substitutes (G2 and G3) to be anastomosed to the cut end of the cervical esophagus. CONCLUSIONS: Thoracic esophageal substitution using the whole stomach showed less anastomotic tension and was less technically demanding than the fundus rotation gastroplasty method. The ex-vivo results support further studies to validate the techniques in clinical cases.(AU)


OBJETIVO: Avaliar, em cadáveres de cães, uma técnica para remoção do esôfago torácico sem toracotomia e dois métodos de substituição do esôfago torácico. MÉTODOS: Foram utilizados 27 cadáveres de cães. Estes foram aleatoriamente divididos em três grupos de nove animais, em que se estudou: G1 - esofagectomia torácica total pelo método de invaginação retrógrada; G2 - esofagectomia torácica total com substituição esofágica pelo estômago inteiro; G3 - esofagectomia torácica total com substituição esofágica por um gastrotubo confeccionado de acordo com a técnica de Büchler de gastroplastia por rotação do fundo. Após a ressecção esofágica no grupo 1, a integridade da rota intratorácica foi avaliada por endoscopia e solução de azul de metileno a 1 por cento. RESULTADOS: A ruptura da pleura visceral ocorreu em todos os animais, especialmente no terço caudal. Entretanto, a rota transtorácica mediastinal permitiu a elevação de ambos os substitutos esofágicos (G2 e G3) para a realização da anastomose com a extremidade caudal do esôfago cervical. CONCLUSÕES: A substituição por estômago inteiro apresentou menor tensão na anastomose, maior facilidade e rapidez comparada à técnica de gastroplastia por rotação do fundo. Os resultados em cadáveres suportam a realização de estudos clínicos para validação da técnica.(AU)

Resumo

Embora a esofagectomia com substituição gástrica total ou por gastrotubo seja procedimento comum em pacientes humanos, há poucos relatos de sua utilização em casos clínicos na medicina veterinária, especialmente quando envolve grandes extensões que incluam o esôfago torácico. O presente trabalho avaliou, em cadáveres de cães, uma técnica para remoção do esôfago torácico sem toracotomia e dois métodos de substituição do esôfago torácico, visando o tratamento de afecções pertinentes a essa espécie. Foram utilizados 27 cadáveres de cães que vieram a óbito por causas não relacionadas ao experimento. Estes foram aleatoriamente divididos em três grupos de nove animais, em que se estudou: G1 ? esofagectomia torácica total pelo método de invaginação retrógrada; G2 ? esofagectomia torácica total com substituição esofágica pelo estômago inteiro; G3 ? esofagectomia torácica total com substituição esofágica por um gastrotubo confeccionado de acordo com a técnica de Büchler de gastroplastia por rotação do fundo. Também foi realizada, nos grupos 2 e 3, uma piloroplastia pela técnica de Heineke-Mikulicz. Após a ressecção esofágica no grupo 1, a integridade da rota intratorácica foi avaliada por endoscopia e solução de azul de metileno a 1%. A ruptura da pleura visceral ocorreu em todos os animais, especialmente no terço caudal. Entretanto, a rota transtorácica mediastinal permitiu a elevação de ambos os substitutos esofágicos (G2 e G3) para a realização da anastomose com a extremidade caudal do esôfago cervical. A substituição por estômago inteiro apresentou menor tensão na anastomose, maior facilidade e rapidez comparada à técnica de gastroplastia por rotação do fundo. Os resultados em cadáveres suportam a realização de estudos clínicos para validação da técnica


Use of whole stomach or gastric tubes as substitutes for the esophagus are common procedures in human patients, but there are few clinical reports of their use in small animals, especially involving large extension of the intrathoracic esophagus. The present study evaluated in dogs, ex vivo, one technique to remove the thoracic esophagus without thoracotomy and two methods of thoracic esophageal replacement aiming for the treatment of diseases associated with this specie. Twenty-seven dogs which died or were euthanatized for reasons unrelated to this study were used. The dogs were randomly divided into three groups of nine animals each to evaluate: G1 ? total thoracic esophagectomy by everting stripping method; G2 ? total thoracic esophagectomy and esophageal substitution using whole stomach; G3 ? total thoracic esophagectomy and esophageal substitution using fundus rotation gastroplasty according to the method of Büchler. Heineke-Mikulicz pyloroplasty was performed in both G2 and G3. After esophageal resection in G1, the integrity of the intrathoracic route was evaluated by endoscopy and test with 1% methylene blue solution. Visceral pleura rupture was observed in all animals, especially in the caudal third portion. However, this mediastinal intrathoracic route allowed that both substitutes for esophagus (G2 and G3) could be brought up to be anastomosed to the cut end of the cervical esophagus. Thoracic esophageal substitution using whole stomach showed less anastomotic tension and was less technically demanding than fundus rotation gastroplasty method. The results ex vivo support future studies to validate the techniques in clinical cases
