Randomized, double-blind, placebo-controlled study of the analgesic effect of intraoperative esmolol for laparoscopic gastroplasty

Abstract 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.

Short-Term Analysis of Food Tolerance and Quality of Life after Laparoscopic Greater Curvature Plication

PURPOSE: The aim of this study was to compare short-term outcomes [food tolerance scores (FTS) and quality of life] after three types of restrictive bariatric surgery: laparoscopic adjustable gastric banding (LAGB), laparoscopic greater curvature plication (LGCP), and laparoscopic sleeve gastrectomy (LSG). MATERIALS AND METHODS: From January 2012 to December 2013, all patients that underwent primary surgery were included in one of the LAGB, LGCP, or LSG groups. These three groups were then compared with respect to FTS, gastrointestinal quality of life indices (GIQLI), and the Medical Outcomes Study Short-Form 36 (SF-36) questionnaire. Questionnaires were sent to all patients both pre- and post-operatively. RESULTS: A total of 85 patients (LAGB=45, LGCP=22, and LSG=18) returned the questionnaires in full, and these patients constituted the study cohort. The cohort was predominately female (n=73, 85.9%). Mean percentage excess weight loss (%EWL) values after LAGB, LGCP, and LSG were 65.4+/-27.0%, 65.6+/-25.2%, and 82.7+/-21.7%, respectively (p=0.044). Mean postoperative FTSs and improvements in total GIQLIs after LAGB, LGCP, and LSG were 15.96, 20.95, and 21.33 and -3.40, 6.68, and 18.78, respectively (p<0.05). All procedures produced improvements in the three SF-36 domain scores. Subgroup analysis revealed significant differences between the three procedures in terms of improvements in general health and emotional well-being. CONCLUSION: LGCP is safe and effective at achieving significant weight loss. In terms of food tolerance and GI quality of life, LGCP was found to be comparable to gastric banding and sleeve gastrectomy.

Esophagectomy with gastroplasty in advanced megaesophagus: late results of omeprazole use / Esofagectomia com gastroplastia no megaesôfago avançado: análise tardia da importância do uso do omeprazol

Objective: To analyze the late results of advanced Chagasic megaesophagus treatment by esophagectomy associated with the use of proton pump inhibitor (omeprazole) as for the incidence of esophagitis and Barrett's esophagus in the remaining stump. Methods : We studied patients with advanced megaesophagus undergoing esophagectomy and transmediastinal esophagogastroplasty. Patients were divided into three groups: A (20) with esophageal replacement by full stomach, without the use of omeprazole; B (20) with esophageal replacement by full stomach, with omeprazole 40 mg/day introduced after the first postoperative endoscopy and maintained for six years; and C (30) with esophageal replacement by gastric tube with use of omeprazole. Dysphagia, weight loss and BMI were clinical parameters we analyzed. Upper gastrointestinal endoscopy was performed in all patients, and determined the height of the anastomosis, the aspect of the mucosa, with special attention to possible injuries arising from gastroesophageal reflux, and the patency of the esophagogastric anastomosis. Results : We studied 50 patients, 28 males (56%) and 22 (44%) females. All underwent endoscopy every year. In the first endoscopy, erosive esophagitis was present in nine patients (18%) and Barrett's esophagus, in four (8%); in the last endoscopy, erosive esophagitis was present in five patients (8%) and Barrett's esophagus in one (2%). When comparing groups B and C, there was no evidence that the manufacturing of a gastric tube reduced esophagitis and Barrett's esophagus. However, when comparing groups A and C, omeprazole use was correlated with reduction of reflux complications such as esophagitis and Barrett's esophagus (p <0.005). Conclusion : The use of omeprazole (40 mg/day) reduced the onset of erosive esophagitis and Barrett's esophagus during the late postoperative period.

Objetivo : analisar os resultados tardios do tratamento do megaesôfago chagásico avançado através da esofagectomia associada ao IBP (omeprazol), com vistas à incidência de esofagite e esôfago de Barrett do coto esofagiano remanescente. Métodos : foram estudados pacientes com megaesôfago avançado submetidos à esofagectomia e à esofagogastroplastia transmediastinal posterior. Os pacientes foram distribuídos em três grupos: A (20) com substituição esofagiana por meio do estômago total, sem o uso do omeprazol; B (20) com substituição esofagiana por meio do estômago total, sem o uso do omeprazol durante este período; após a primeira endoscopia, realizada no pós-operatório, foi introduzido IBP (omeprazol 40mg/dia) e mantido por seis anos; e C (30) com substituição esofagiana por meio do tubo gástrico com uso do omeprazol. A disfagia, a perda ponderal e o IMC foram os parâmetros clínicos analisados. A endoscopia digestiva alta foi realizada em todos os pacientes. Foi determinada a altura da anastomose, a aparência do aspecto da mucosa, com especial atenção para possíveis lesões oriundas de refluxo gastresofágico, a patência da anastomose esofagogástrica. Resultados : na primeira endoscopia, a esofagite erosiva esteve presente em nove pacientes (18%) e o esôfago Barrett, em quatro (8%); na última endoscopia, a esofagite erosiva esteve presente em quatro pacientes (8%) e o esôfago de Barrett em um (2%). Comparando-se os grupos B e C, não houve redução da esofagite e do esôfago de Barrett. Porém, comparando-se os grupos A e C, houve redução de complicações do refluxo, como esofagite e o esôfago de Barrett (p<0,005). Conclusão : os resultados obtidos permitem concluir que o uso de omeprazol (40mg/dia) reduziu o aparecimento de esofagite erosiva e esôfago de Barrett no decorrer do pós-operatório tardio.

Abordagem do segmento superior do corpo em pacientes ex-obesos com cirurgia única: toracobraquio-mamoplastia / Unique surgery for the upper body segment in patients with massive weight loss: thoracobrachio-mammoplasty

INTRODUÇÃO Os pacientes ex-obesos necessitam de uma abordagem complexa, diante do grande excesso de pele decorrente da perda ponderal. Em alguns casos, muitas cirurgias plásticas são necessárias, não havendo uma padronização na associação destas cirurgias. No segmento superior do corpo, a região dos braços, a lateral do tórax e as mamas normalmente são acometidas, principalmente nas mulheres. Diversas técnicas foram desenvolvidas com o objetivo de alcançar resultados melhores e com cicatrizes mais escondidas. Algumas técnicas podem ser associadas, sendo realizadas em um único tempo cirúrgico. Quando a equipe é bem estruturada, o tempo cirúrgico é reduzido, significando mais segurança para o paciente. MÉTODO: Os autores apresentam uma técnica que oferece padronização no tratamento do ex-obeso, que é realizada em tempo único: a Mamoplastia (pela técnica de Pitanguy ou com aposição de prótese mamária), a Toracoplastia (com a retirada do excesso de pele na lateral do tórax) e a Braquioplastia (realizada com um desenho retilíneo na parte mais inferior dos braços). RESULTADOS: Os sete casos foram avaliados quanto ao tempo cirúrgico, à localização das cicatrizes, à forma final e à simetria. Entre as complicações, houve deiscências parciais (14%) e cicatrizes hipertróficas (14%). O resultado estético foi satisfatório para os pacientes em 84% dos casos, sendo que a qualidade da cicatrização do paciente, queloide ou cicatrizes hipercrômicas, foi a maior causa de insatisfação. CONCLUSÃO: A utilização da técnica de Toracobraquio-mamoplastia em um único tempo se mostrou efetiva no tratamento do ex-obeso, oferecendo mais uma opção, diante das outras cirurgias que estes pacientes normalmente necessitam.

INTRODUCTION Ex-obese patients require a complex surgical approach because of the large amount of excess skin due to their massive weight loss. In some cases, several plastic surgeries are needed, and there is no existing standard in the coordination of these surgeries. In the upper segment of the body, the arms, side of the thorax, and breasts are usually affected, mainly in women. Several techniques have been developed with the aim of achieving better results with better hidden scars. Some techniques may be associated, being carried out in a single surgical procedure. A well-structured surgical team leads to a reduced surgical time, which means higher safety for the patient. METHOD: We present a technique for standardization in the treatment of ex-obese patients that is performed in a single step, comprising mammoplasty (according to Pitanguy's technique or with placement of breast prosthesis), thoracoplasty (with the removal of excess skin on the side of the chest), and brachioplasty (performed with a rectilinear drawing at the lowest part of the arms). RESULTS: Seven cases were evaluated in terms of surgical time, location of the scars, and final shape and symmetry. The complications included partial dehiscence (14%) and hypertrophic scars (14%). The aesthetic result was satisfactory for 84% of the patients; on the other hand, the quality of cicatrization, keloid, and hypertrophic scars were the major causes of dissatisfaction. CONCLUSION: The use of the thoracobrachio-mammoplasty technique in a single surgical time was effective in the treatment of ex-obese patients, offering yet another option among other surgeries that these patients usually need.

Cirurgia plástica pós-gastroplastia: perfil das deficiências nutricionais com implicações na cicatrização / Plastic surgery after gastroplasty: nutritional deficiency profile with wound-healing implications

INTRODUÇÃO: Os cirurgiões plásticos têm recebido em seus consultórios e ambulatórios um número cada vez maior de pacientes com queixa de deformidade do contorno corporal após maciças perdas ponderais secundárias a cirurgias bariátricas. Todavia, em função das restrições alimentares e disabsorções cirúrgicas, são frequentes complicações metabólicas e distúrbios nutricionais no pós-operatório tardio das gastroplastias. O objetivo deste estudo é detectar a prevalência dos principais distúrbios nutricionais relacionados à cicatrização em pacientes de ambulatório especializado em cirurgia plástica do paciente pós-gastroplastia. MÉTODO: é um estudo observacional, transversal e descritivo, em que os pacientes foram avaliados clinicamente e através de protocolo laboratorial. RESULTADOS: foram avaliados 32 pacientes com gastroplastia há pelo menos dois anos e estabilidade ponderal há no mínimo seis meses. Os principais distúrbios detectados foram: anemia (56% dos pacientes), com carências na bioquímica do ferro (31,2%) e da vitamina B12 (25%), bem como deficiências dos íons zinco (18,7%) e cobre (3,1%). Houve carências discretas no perfil proteico e ausência de déficits na bioquímica básica e lipidograma. CONCLUSÃO: é dever do cirurgião plástico conhecer a fundo a prevalência dos principais distúrbios nutricionais relacionados à cicatrização na população de pacientes pós-gastroplastia no sentido de corrigir eventuais carências e prevenir complicações. Sabe-se, contudo, que ainda são necessários mais estudos para correlacionar qualquer deficiência alimentar às intercorrências observadas no pós-operatório deste grupo de pacientes.

INTRODUCTION: Plastic surgeons have received in their outpatient clinics an increasing number of patients complaining of body contour defects due to the massive weight loss after a bariatric surgery. However, owing to dietary restrictions and surgical desorption, metabolic complications and nutritional disorders are commonly observed in the late postoperative period after gastroplasty. The aim of this study was to determine the prevalence of major nutritional disorders related to healing in patients at a specialized outpatient plastic surgery clinic who underwent gastroplasty. METHOD: This is an observational, transversal, and descriptive study, in which a laboratory protocol was used to clinically evaluate and assess the patients. RESULTS: Thirty-two patients who underwent gastroplasty at least 2 years previously with weight stability for at least 6 months were evaluated. The major disorders identified included anemia (56% of patients) and deficiency in iron (31.2%), vitamin B12 (25%), zinc ions (18.7%), and copper (3.1%). Mild deficiencies in the protein profile were also observed; however, no deficiencies in basic and lipid biochemistry were noted. CONCLUSION: The plastic surgeon should have an in-depth knowledge about the prevalence of the major nutritional disorders related to healing in postbariatric patients, to allow correction of possible deficiencies and prevention of complications. However, more studies would be required to correlate any dietary deficiency to the complications observed in the postoperative period in this group of patients.

Three-Year Experience of Pouch Dilatation and Slippage Management after Laparoscopic Adjustable Gastric Banding

PURPOSE: Pouch dilatation and band slippage are the most common long-term complications after laparoscopic adjustable gastric banding (LAGB). The aim of the study is to present our experience of diagnosis and management of these complications. MATERIALS AND METHODS: The pars flaccida technique with anterior fixation of the fundus was routinely used. All band adjustments were performed under fluoroscopy. We analyzed the incidence, clinico-radiologic features, management, and revisional surgeries for treatment of these complications. We further presented the outcome of gastric plication techniques as a measure for prevention of these complications. RESULTS: From March 2009 to March 2012, we performed LAGB on 126 morbidly obese patients. Among them, 14 patients (11.1%) were diagnosed as having these complications. Four patients (3.2%) had concentric pouch dilatations, which were corrected by band adjustment. Ten (7.9%) had eccentric pouch with band slippage. Among the ten patients, there were three cases of posterior slippage, which were corrected by reoperation, and seven cases of eccentric pouch dilatation with anterior slippage. Three were early anterior slippage, which was managed conservatively. Two were acute anterior slippage, one of whom underwent a revision. There were two cases of chronic anterior slippage, one of whom underwent a revision. The 27 patients who underwent gastric plication did not present with eccentric pouch with band slippage during the follow-up period. CONCLUSION: The incidence of pouch dilatation with/without band slippage was 11.1%. Management should be individualized according to clinico-radiologic patterns. Gastric plication below the band might prevent these complications.

Fístula gastrobronquial post gastrectomía en manga / Gastrobronchial fistula post sleeve gastrectomy

Se presenta el caso de una paciente mujer de 35 años de edad operada por obesidad mórbida con índice de masa corporal (IMC) de 45, que fue referida por presentar fistula gastrobronquial post gastrectomía en manga la que no cicatrizó con medidas endoscópicas requiriendo manejo quirúrgico de resección total del remanente gástrico con reconstrucción en Y de Roux como opción curativa.

A 35 years old female with morbid obesity IMC 45 was referred because of a gastrobronchial fistula developed post sleeve gastrectomy initially treated with endoscopic techniques without improvement, reason why a total resection of the gastric remanent with a Roux en Y reconstruction was done as an option with successful result.

Acrodermatitis due to zinc deficiency after combined vertical gastroplasty with jejunoileal bypass: case report / Acrodermatite por deficiência de zinco após associação de gastroplastia vertical com derivação jejuno-ileal: relato de caso

CONTEXT: Nutritional complications may occur after bariatric surgery, due to restriction of food intake and impaired digestion or absorption of nutrients. CASE REPORT: After undergoing vertical gastroplasty and jejunoileal bypass, a female patient presented marked weight loss and protein deficiency. Seven months after the bariatric surgery, she presented dermatological features compatible with acrodermatitis enteropathica, as seen from the plasma zinc levels, which were below the reference values (34.4 mg%). The skin lesions improved significantly after 1,000 mg/day of zinc sulfate supplementation for one week. CONCLUSIONS: The patient's evolution shows that the multidisciplinary team involved in surgical treatment of obesity should take nutritional deficiencies into consideration in the differential diagnosis of skin diseases, in order to institute early treatment.

CONTEXTO: Complicações nutricionais podem ocorrer após cirurgia bariátrica, pela restrição no consumo de alimentos e por comprometimento do processo digestivo e absortivo. RELATO DO CASO: Após ter sido submetida a gastroplastia vertical e derivação jejuno-ileal, uma paciente apresentou acentuada perda de peso e desnutrição proteica. Sete meses após a cirurgia bariátrica, manifestou-se quadro dermatológico compatível com acrodermatite enteropática, verificado a partir dos níveis plasmáticos de zinco (34,4 mg%), que se situavam abaixo dos valores de referência. As lesões cutâneas melhoraram significativamente após 1.000 mg/dia de suplementação de sulfato de zinco, por uma semana. CONCLUSÕES: A evolução da paciente mostra que a equipe multiprofissional envolvida no tratamento cirúrgico da obesidade deve considerar as deficiências nutricionais no diagnóstico diferencial das doenças cutâneas, a fim de instituir precocemente o tratamento.

Temporary ileostomy for the preservation of colon fistula in patients with postoperative complications: case report

Among the postoperative complications in the digestive system, the fistulae are the most common ones. The changes resulting from these fistulae are very important, once they can determine the patient's situation and the development of multiple organic failures. This paper reports the case of a patient who had relevant complications after having undergone temporary ileostomy to maintain the colon fistulized. About 90 to 95% of the digestive tract fistulae have spontaneous resolution. In some cases, the general state of the patient compromises the spontaneous closure. In this study, after one month of nutritional support and medicine treatment, the spontaneous closure of the colon fistula did not occur, thus, a surgical intervention was necessary to solve the case. (AU)

Dentre as complicações pós-operatórias do aparelho digestório, as fístulas apresentam alta incidência. As alterações decorrentes dessas fístulas são muito importantes, pois podem determinar o agravamento do estado geral do paciente e o desenvolvimento de insuficiências orgânicas múltiplas. O presente trabalho relata o caso de um paciente com complicações relevantes após a realização de uma ileostomia temporária para preservação do cólon fistulizado. A maioria (90-95%) das fístulas do trato digestório tem resolução espontânea; entretanto, em alguns casos, o estado geral do paciente compromete o fechamento espontâneo. No caso em estudo, após um mês de suporte nutricional e tratamento medicamentoso, o fechamento espontâneo da fístula de cólon não ocorreu, sendo necessária a intervenção cirúrgica para resolução do caso.

Gastrectomía vertical posterior a retiro de banda gástrica / Sleeve gastrectomy performed simultaneously to extraction of a gastric band: experience in 10 patients

Background: Sleeve gastrectomy is replacing gastric banding in the management of morbid obesity. Aim: To report the results of sleeve gastrectomy performed simultaneously with the extraction of a gastric band. Material and Methods: We report ten patients aged 34 to 53 years (nine women) operated between 2008 and 2009. Results: The main indication for sleeve gastrectomy was the failure of the gastric band. No complications were recorded and patients were discharged 72 hours after the procedure. Conclusions: Sleeve gastrectomy can be carried out simultaneously with the extraction of a gastric band, without increasing operative complications.

Introducción: La Gastrectomía Vertical ha reemplazado a la banda gástrica en el manejo de un importante número de pacientes portadores de obesidad. El objetivo de este trabajo es mostrar los resultados de una serie de pacientes, en los que se realizó una Gastrectomía Vertical posterior a la extracción de una banda gástrica en un mismo tiempo operatorio. Método: La serie incluye a 10 pacientes operados entre Mayo de 2008 y Noviembre de 2009. La principal indicación de la Gastrectomía Vertical fue el fracaso de la banda como tratamiento de la obesidad. Resultados: En los 10 pacientes estudiados, la gastrectomía se pudo efectuar sin mayores dificultades ni diferencias con respecto al procedimiento habitual. No existieron complicaciones post operatorias, siendo la totalidad de los pacientes dados de alta dentro de las 72 horas. Conclusión: La Gastrectomía Vertical representa una alternativa de manejo en pacientes portadores de una banda gástrica con indicación de extracción de esta, ya sea por fracaso o por síntomas asociados a su presencia. El procedimiento puede efectuarse de manera segura en el mismo acto operatorio y sus resultados son comparables a los observados cuando la técnica se efectúa en pacientes que no han sido intervenidos previamente.

Avaliação da vitalidade fetal e resultados perinatais em gestações após gastroplastia com derivação em Y de Roux / Assessment of fetal vitality and perinatal results in pregnancies after gastroplasty with Roux-en-Y gastric bypass

OBJETIVO: Analisar os resultados da avaliação da vitalidade fetal de gestações após gastroplastia com derivação em Y de Roux, verificando as complicações maternas e os resultados perinatais. MÉTODOS: No período de julho de 2001 a setembro de 2009, foram analisados, retrospectivamente, dados de prontuário de pacientes com gestação após gastroplastia com derivação em Y de Roux, acompanhadas em pré-natal especializado e cujo parto foi realizado na instituição. Foram analisados os exames de avaliação da vitalidade fetal (cardiotocografia, perfil biofísico fetal e dopplervelocimetria das artérias umbilicais) realizada na semana anterior ao parto. As variáveis maternas investigadas foram: dados demográficos, complicações clínicas maternas, tipo de parto, complicações no parto e pós-parto, exames hematimétricos maternos e resultados perinatais. RESULTADOS: Trinta gestações após gastroplastia com derivação em Y de Roux foram identificadas e 24 delas foram submetidas à avaliação da vitalidade fetal. Todas as pacientes apresentaram resultados normais na cardiotocografia, no perfil biofísico fetal e na dopplervelocimetria das artérias umbilicais. Houve um caso de oligohidrâmnio. A principal complicação observada foi anemia materna (Hb < 11,0 g/dL, 86,7 por cento). A cesárea foi realizada em 21 pacientes (70 por cento). As complicações do parto incluíram um caso de aderências, um de hematoma e infecção de parede e um de histerectomia pós-parto por miomatose e atonia uterina. A proporção de recém-nascidos pequenos para a idade gestacional foi de 23,3 por cento. CONCLUSÃO: Não houve comprometimento do bem-estar fetal em gestações após gastroplastia com derivação em Y de Roux. A principal complicação materna foi a anemia e essas mulheres requerem aconselhamento nutricional específico com ampla avaliação das deficiências de micronutrientes desde o início da gravidez.

OBJECTIVE: To study fetal vitality assessed in pregnancies after gastroplasty with Roux-en-Y gastric bypass'and verify maternal complications and perinatal results. METHODS: Hospital charts of all pregnancies after gastroplasty with Roux-en-Y gastric bypass were reviewed retrospectively. All cases followed at the specialized prenatal care that gave birth in this institution, between July 2001 and September 2009, were reviewed. The assessment of fetal vitality (cardiotocography, fetal biophysical profile and umbilical artery Doppler velocimetry) performed in the last week before delivery were analyzed. The maternal variables investigated were: demographic data, maternal complications, mode of delivery, complications during delivery and postpartum, maternal blood exams and perinatal results. RESULTS: During the study period 30 pregnancies after gastroplasty with Roux-en-Y gastric bypass were identified and 24 of them had undergone assessment of fetal vitality. All patients presented normal cardiotocography, normal fetal biophysical profile and normal results at the umbilical artery Doppler velocimetry. One case presented with oligohydramnios. The main complication observed was maternal anemia (Hb < 11.0 g/dL, 86.7 percent). Cesarean section was performed in 21 pregnancies (70 percent). Delivery complications included one case of adherences, one hematoma and infection of abdominal wall scar and one postpartum hysterectomy for myoma and uterine atony. The proportion of small infants for gestational age was 23.3 percent. CONCLUSION: Fetal vitality was not compromised in pregnancies after gastroplasty with Roux-en-Y gastric bypass. The main maternal complication was anemia, therefore these women require specific nutritional counseling and a broad evaluation for micronutrient deficiencies at early pregnancy.

development of migration in laparoscopic adjustable gastric banding and the approach to treatment

Laparoscopic adjustable gastric banding [LAGB] application in the treatment of morbid obesity has many advantages. However, certain complications, such as intragastric migration, may occur. In the present study, the effects of such migration and surgical treatment methods were investigated. One hundred thirty-four patients underwent LAGB via the Pars Flaccida technique. Of the patients mean age was 27 years [18-54]. Migration was suspected based on disappearance of the band-related stricture barium contrast examination of the stomach and duodenum. Migration was definitely diagnosed during gastroscopy. Migration was diagnosed in four [3%] of 134 patients, as well as in one case who underwent LAGB in another center. The follow-up time was 14 months [2-21] and, their mean body mass index [BMI] was 47 kg/m2 [39-56]. The band was removed in four patients, the opening formed in the stomach was sutured primarily. One of the patients underwent cholecistectomy and Roux-en-Y gastroenterostomy [RNYGE]. The development of migration after LAGB is a long-term complication. Gastric bands should be removed as soon as the migration is diagnosed. RNYGE in the same session, or new band application 3-6 months later

[Evaluation of gastric surgery complications and their management in patients hospitalized at Ayatollah Taleghani hospital]

Gastric surgeries are still among the major causes of surgery complications. Study on prevalence of these complications and recognition of their risk factors are strongly needed. To study Gastric surgery complications and strategies for their management in patients hospitalized at Ayatollah Taleghani hospital. In this Cross-sectional study all gastric surgeries at Ayatollah Taleghani hospital between 1994 and 2002 were assessed. Variables were age, sex, type of surgery, indication of surgery, type of complication and management strategy [medical or surgical]. Data were collected from patients' medical records. Indications for surgery were gastric malignancy and neoplasia in 277 patients [59.8%], peptic ulcer in 151 [32.6%], and other causes in 7.6%. The most prevalent surgeries were Billroth II [23%] and total gastrectomy [15%]. The highest level of complications was observed in Billroth II [24%]. Complications of surgery occurred in 42 cases [9%] among those 33 males and 9 females. Except for vagotomy and pyloroplasty, less than 50% of complications needed surgical management. This study showed that the prevalence of gastric surgeries complications is 9%, comparable to those found in other studies. The most prevalent surgeries were Billroth II and total gastrectomy, believed to be associated with relatively higher level of complications

Banda gástrica y gestación / Gastric band and pregnancy

Se presenta un caso de gestación en paciente obesa mórbida portadora de banda gástrica laparoscópica ajustable, que se descomprimió en el primer trimestre. En la evolución de la gestación destaca incremento ponderal de 3 kg y cuadro de suboclusion y marasmo en el tercer trimestre que obligó a la interrupción de la gestación mediante cesárea, produciéndose broncoaspiración y choque séptico secundario. Se revisa las series publicadas de embarazadas portadoras de banda gástrica y las complicaciones descritas en la gestación.

A case report is presented of a patient who became pregnant a year after morbid obesity surgery, the main complications of laparoscopy adjustable gastric band during pregnancy are discussed. In this case, the gastric band was adjusted to prevent first trimester vomiting. We observed the following complications: weight gain during pregnancy was limited to three kilograms and ileus and marasmus developed in the third trimester making pregnancy termination mandatory. During cesarean section the patient suffered aspiration pneumonia and secondary septic shock.

Bezoar gástrico como complicación de banda gástrica en manejo de obesidad mórbida: caso clínico / Gastric bezoar as complication of gastric banding: report of one case

Laparoscopic adjustable gastric banding (LAGB) is used for the management of morbid obesity. Phytobezoars are rarely reported as a complication of this operation and are usually extracted by endoscopic means. We report a 48 year-old male subjected to a gastric banding, that consulted for progressive dysphagia, six months after the operation. A barium meal x-ray examination demonstrated the presence of a bezoar that was dissolved in one week using papain. A control barium meal confirmed the disappearance of the bezoar.

Tratamento das hérnias incisionais nas abdominoplastias multifuncionais / Incisional hernias treatment on multifunctional abdominoplasties

Introdução: Os pacientes que são submetidos a cirurgias bariátricas freqüentemente evoluem com hérnias de parede abdominal, sejam estas imperceptíveis ao exame físico ou mesmo grandes eventrações com perda de domicílio. Método: Neste artigo, os autores relatam suas experiências com o tratamento destas hérnias durante a abdominoplastia multifuncional, pormeio do isolamento e redução do saco herniário e síntese primária da falha aponeurótica com posterior plicatura desta, sem o uso de materiais aloplásticos. Foi realizado um estudoretrospectivo abrangendo um total de 44 pacientes, num período de cinco anos e meio, onde a eficácia e segurança da técnica foram analisadas.

Introduction: Abdominal wall hernias frequently occur after open bariatric surgical procedures, which may be imperceptible during physical examination or very remarkable asbig eventrations with loss of domain. Methods: In this article, the authors report their experience with the treatment of these hernias during the multifunctional abdominoplasty,thru the isolation and reduction of the herniary sac, primary synthesis of the defect and plicature of the aponeurosis, without using aloplastic materials. The authors made a retrospective study with 44 patients, over five and a half year’s period, where the effectiveness and safety of the technique were analized.

Fístula gastrobrônquica como complicação rara de gastroplastia para obesidade: relato de dois casos / Gastrobronchial fistula as a rare complication of gastroplasty for obesity: a report of two cases

A fístula gastrobrônquica é uma condição rara como complicação decorrente de cirurgia da obesidade. O seu manejo exige a participação ativa de um pneumologista, o qual deve conhecer alguns aspectos dos principais tipos de cirurgia bariátrica. Neste relato, descrevemos dois casos de pacientes que apresentaram abscessos subfrênico e pulmonar recidivantes secundários a fístula no ângulo de His durante 19,5 meses, em média. Após o insucesso das relaparotomias, a cura foi obtida por meio da antibioticoterapia e, principalmente, por meio da estenostomia e da dilatação endoscópica, além do uso de clipes e cola de fibrina na fístula. Estas complicações pulmonares não devem ser tratadas isoladamente sem uma avaliação gastrintestinal pois isso pode resultar em piora do quadro respiratório, dificultando o manejo anestesiológico durante procedimentos endoscópicos.

Gastrobronchial fistula is a rare condition as a complication following bariatric surgery. The management of this condition requires the active participation of a pulmonologist, who should be familiar with aspects of the main types of bariatric surgery. Herein, we report the cases of two patients who presented recurrent subphrenic and lung abscess secondary to fistula at the angle of His for an average of 19.5 months. After relaparotomy was unsuccessful, cure was achieved by antibiotic therapy and, more importantly, by stenostomy and endoscopic dilatation, together with the use of clips and fibrin glue in the fistula. These pulmonary complications should not be treated in isolation without a gastrointestinal evaluation since this can result in worsening of the respiratory condition, thus making anesthetic management difficult during endoscopic procedures.
