RESUMO
Despite endoscopic eradication therapy being an effective and durable treatment for Barrett's esophagus-related neoplasia, even after achieving initial successful eradication, these patients remain at risk of recurrence and require ongoing routine examinations. Failure of radiofrequency ablation and argon plasma coagulation is reported in 10-20% of cases.

La disfagia alta es un síntoma frecuente de consulta al otorrinolaringólogo o gastroenteròlogo. Los diagnósticos diferenciales son trastornos de la deglución por daño neurològico, anillos esofágicos superiores, globus faríngeo, neoplasia, disfagia lusoria y trastornos motores inespecífico y otras más raras aún. Hay escasa literatura actualizada en pacientes adultos. El diagnóstico se basa en el estudio radiológico baritado, endoscopia y complementariamente con manometría. Las opciones de tratamiento son motivo de discusión, dada la poca evidencia disponible. En este artículo se presentan los resultados observados en una cohorte de 10 pacientes con diagnóstico confirmado de acalasia del cricofaríngeo sometidos a dilatación endoscópica (7 pacientes) o miotomía quirúrgica por cervicotomía (3 pacientes). Se evaluó evolución de la disfagia, complicaciones post procedimiento y resultados a largo plazo. No hubo complicaciones mayores, la disfagia mejoro en ambos grupos, en el grupo de dilatación se complementó el tratamiento con dilataciones periódicas en 2 pacientes. No hubo diferencias significativas en los 2 grupos estudiados. Conclusión: ambas opciones terapéuticas presentan buenos resultados en el tratamiento de estos pacientes.
Dysphagia at cervical level is a frequent symptom causing visit to otolaryngologist or gastroenterologist. The differential diagnoses are swallowing disorders due to neurological damage, upper esophageal rings, pharyngeal globus, neoplasia, non-specific motor disorders and other even rarer ones. There is little updated literature in adult patients. The diagnosis is based on the barium radiological study, endoscopy and complementary manometry. Treatment options are a matter of discussion, given the little evidence available. This paper presents the results observed in a cohort of 10 patients with a confirmed diagnosis of cricopharyngeal achalasia who underwent endoscopic dilation (7 patients) or surgical myotomy by cervicotomy (3 patients). The evolution of dysphagia, post-procedure complications and long-term results were evaluated. There were no major complications, dysphagia improved in both groups, in the dilation group the treatment was supplemented with periodic dilations in 2 patients. There were no significant differences in the 2 groups studied. Conclusion: both therapeutic options present good results in the treatment of these patients.
RESUMO
BACKGROUND: The preoperative nutritional state has prognostic postoperative value. Tomographic density and area of psoas muscle are validated tools for assessing nutritional status. There are few reports assessing the utility of staging tomography in gastric cancer patients in this field. AIMS: This study aimed to determine the influence of sarcopenia, measured by a preoperative staging computed tomography scan, on postoperative morbimortality and long-term survival in patients operated on for gastric cancer with curative intent. METHODS: This retrospective study was conducted from 2007 to 2013. The definition of radiological sarcopenia was by measurement of cross-sectional area and density of psoas muscle at the L3 (third lumbar vertebra) level in an axial cut of an abdominopelvic computed tomography scan (in the selection without intravascular contrast media). The software used was OsirixX version 10.0.2, with the tool "propagate segmentation", and all muscle seen in the image was manually adjusted. RESULTS: We included 70 patients, 77% men, with a mean cross-sectional in L3 of 16.6 cm2 (standard deviation+6.1) and mean density of psoas muscle in L3 of 36.1 mean muscle density (standard deviation+7.1). Advanced cancers were 86, 28.6% had signet-ring cells, 78.6% required a total gastrectomy, postoperative surgical morbidity and mortality were 22.8 and 2.8%, respectively, and overall 5-year long-term survival was 57.1%. In the multivariate analysis, cross-sectional area failed to predict surgical morbidity (p=0.4) and 5-year long-term survival (p=0.34), while density of psoas muscle was able to predict anastomotic fistulas (p=0.009; OR 0.86; 95%CI 0.76-0.96) and 5-year long-term survival (p=0.04; OR 2.9; 95%CI 1.04-8.15). CONCLUSIONS: Tomographic diagnosis of sarcopenia from density of psoas muscle can predict anastomotic fistulas and long-term survival in gastric cancer patients treated with curative intent.

RESUMO RACIONAL: O estado nutricional pré-operatório tem valor prognóstico pós-operatório. A densidade tomográfica e a área do músculo psoas é uma ferramenta validada para o estado nutricional. Existem poucos estudos avaliando a utilidade da tomografia de estadiamento em pacientes com câncer gástrico neste campo. OBJETIVOS: Determinar a influência da sarcopenia, medida por tomografia computadorizada de estadiamento pré-operatório, na morbimortalidade pós-operatória e sobrevida em longo prazo em pacientes operados de câncer gástrico com intenção curativa. MÉTODOS: Estudo retrospectivo de 2007 a 2013. A definição de sarcopenia radiológica foi pela medida da área (PA) e densidade do músculo psoas (PD) a nível de L3 (Terceira vertebra lombar), em um corte axial de tomografia computadorizada abdominopélvica (na seleção sem meio de contraste intravascular). O Software utilizado foi o OsirixX v 10.0.2, com a ferramenta "propagar segmentação", ajustando manualmente todos os músculos vistos na imagem. RESULTADOS: Foram incluídos 70 pacientes, 77% homens, PA média em L3: 16,6 cm2 (desvio padrão+6,1), PD média em L3: 36,1 mean muscle density (desvio padrão+7,1). Os cânceres avançados foram de 86, 28,6% tinham células em anel de sinete, 78,6% necessitaram de gastrectomia total, a morbidade e mortalidade cirúrgica pós-operatória foi de 22,8 e 2,8%, respectivamente, a sobrevida global de 5 anos a longo prazo (SV5) foi de 57,1%. Na análise multivariada, PA falhou em prever morbidade cirúrgica (p=0,4) e sobrevida global de 5 anos (p=0,34), enquanto PD foi capaz de prever fístulas anastomóticas (p=0,009; OR 0,86; IC95% 0,76-0,96) e SV5 (p=0,04; OR 2,9; IC95% 1,04-8,15). CONCLUSÕES: O diagnóstico tomográfico de sarcopenia por desvio padrão é capaz de predizer fístulas anastomóticas e sobrevida a longo prazo em pacientes com câncer gástrico tratados com intenção curativa.
RESUMO
ABSTRACT BACKGROUND: The addition of endoscopic ablative therapy plus proton pump inhibitors or fundoplication is postulated for the treatment of patients with long-segment Barrett´s esophagus (LSBE); however, it does not avoid acid and bile reflux in these patients. Fundoplication with distal gastrectomy and Roux-en-Y gastrojejunostomy is proposed as an acid suppression-duodenal diversion procedure demonstrating excellent results at long-term follow-up. There are no reports on therapeutic strategy with this combination. AIMS: To determine the early and long-term results observed in LSBE patients with or without low-grade dysplasia who underwent the acid suppression-duodenal diversion procedure combined with endoscopic therapy. METHODS: Prospective study including patients with endoscopic LSBE using the Prague classification for circumferential and maximal lengths and confirmed by histological study. Patients were submitted to argon plasma coagulation (21) or radiofrequency ablation (31). After receiving treatment, they were monitored at early and late follow-up (5-12 years) with endoscopic and histologic evaluation. RESULTS: Few complications (ulcers or strictures) were observed after the procedure. Re-treatment was required in both groups of patients. The reduction in length of metaplastic epithelium was significantly better after radiofrequency ablation compared to argon plasma coagulation (10.95 vs 21.15 mms for circumferential length; and 30.96 vs 44.41 mms for maximal length). Intestinal metaplasia disappeared in a high percentage of patients, and histological long-term results were quite similar in both groups. CONCLUSIONS: Endoscopic procedures combined with fundoplication plus acid suppression with duodenal diversion technique to eliminate metaplastic epithelium of distal esophagus could be considered a good alternative option for LSBE treatment.
RESUMO RACIONAL: A adição de terapia ablativa endoscópica associado a inibidores da bomba de prótons ou fundoplicatura tem sido postulada para o tratamento de pacientes com esôfago de Barrett de segmento longo (EBSL), no entanto, essa conduta não evita o refluxo ácido/biliar nesses pacientes. A fundoplicatura com gastrectomia distal e gastrojejunostomia em Y de Roux (FGD-Y) foi proposta como procedimento de supressão de ácido, demonstrando excelentes resultados no seguimento a longo prazo. Não há relatos na literature com a combinação dessa estratégia terapêutica. OBJETIVOS: Determinar os resultados precoces e a longo prazo observados em pacientes com EBSL com ou sem dysplasia de baixo grau, submetidos a FGD-Y, combinado com terapia endoscópica. MÉTODOS: Estudo prospectivo incluindo pacientes com EBSL, empregando a classificação de Praga, sendo o comprimento circunferencial (C) e máximo (M) e confirmado por estudo histológico. Os pacientes foram submetidos à coagulação com plasma de argônio (CPA, 21 pacientes) ou ablação por radiofrequência (ARF, 31 pacientes). Após o tratamento, eles foram seguidos precoce e tardiamente (5-12 anos), mediante avaliação endoscópica e histológica. RESULTADOS: Foram observadas poucas complicações após o procedimento (úlcera ou estenose). Re-tratamento foi necessário em ambos os grupos de pacientes. A redução do comprimento do epitélio metaplásico foi significativamente melhor após ARF em comparação com CPA (10,95 versus 21,15 mm para C e 30,96 versus 44,41 mm para M). A metaplasia intestinal desapareceu em elevada porcentagem de pacientes, e os resultados histológicos a longo prazo foram bastante semelhantes em ambos os grupos. CONCLUSÕES: Procedimentos endoscópicos combinados com fundoplicatura e gastrectomia distal e gastrojejunostomia em Y de Roux, para eliminar o epitélio metaplásico do esôfago distal podem ser considerados uma boa opção alternativa para o tratamento da EBSL.

RESUMO Apesar de a terapia de erradicação endoscópica ser um tratamento eficaz e durável para a neoplasia relacionada ao esôfago de Barrett (BE), mesmo após a erradicação inicial bem-sucedida, esses pacientes permanecem em risco de recorrência e requerem exames de rotina contínuos. A falha na ablação por radiofrequência e na coagulação com plasma de argônio é relatada em 10-20% dos casos.
RESUMO
BACKGROUND: Laparoscopic Nissen fundoplication fails to control the gastroesophageal reflux in almost 15% of patients, and most of them must be reoperated due to postoperative symptoms. Different surgical options have been suggested. AIMS: This study aimed to present the postoperative outcomes of patients submitted to three different procedures: redo laparoscopic Nissen fundoplication alone (Group A), redo laparoscopic Nissen fundoplication combined with distal gastrectomy (Group B), or conversion to laparoscopic Toupet combined with distal gastrectomy with Roux-en-Y gastrojejunostomy (Group C). METHODS: This is a prospective study involving 77 patients who were submitted initially to laparoscopic Nissen fundoplication and presented recurrence of gastroesophageal reflux after the operation. They were evaluated before and after the reoperation with clinical questionnaire and objective functional studies. After reestablishing the anatomy of the esophagogastric junction, a surgery was performed. None of the patients were lost during follow-up. RESULTS: Persistent symptoms were observed more frequently in Group A or B patients, including wrap stricture, intrathoracic wrap, or twisted fundoplication. In Group C, recurrent symptoms associated with this anatomic alteration were infrequently observed. Incompetent lower esophageal sphincter was confirmed in 57.7% of patients included in Group A, compared to 17.2% after Nissen and distal gastrectomy and 26% after Toupet procedure plus distal gastrectomy. In Group C, despite the high percentage of patients with incompetent lower esophageal sphincter, 8.7% had abnormal acid reflux after surgery. CONCLUSIONS: Nissen and Toupet procedures combined with Roux-en-Y distal gastrectomy are safe and effective for the management of failed Nissen fundoplication. However, Toupet technique is preferable for patients suffering from mainly dysphagia and pain.

Giant paraesophageal hernias (GPHH) occur frequently in the elderly and account for about 5-10% of all hiatal hernias. Up to now controversy persists between expected medical treatment and surgical treatment. To assess if an indication for surgical repair of GPHH is possible in elderly patients. A prospective study that includes patients over 70 years of age hospitalized from January 2015 to December 2019 with GPHH. Patients were separated into Group A and Group B. Group A consisted of a cohort of 23 patients in whom observation and medical treatment were performed. Group B consisted of 44 patients submitted to elective laparoscopic hiatal hernia repair. Symptomatic patients were observed in both groups (20/23 in Group A and 38/44 in Group B). Charlson's score >6 and ASA II or III were more frequent in Group A. Patients in Group A presented symptoms many years before their hospitalization in comparison to Group B (21.8+7.8 vs. 6.2+3.5 years, respectively) (P=0.0001). Emergency hospitalization was observed exclusively in Group A. Acute complications were frequently observed and hospital stays were significantly longer in Group A, 14 patients were subjected to medical management and 6 to emergency surgery. In-hospital mortality occurred in 13/20 patients (65%) versus 1/38 patients (2.6%) in Group B (P=0.0001). Laparoscopic paraesophageal hiatal hernia repair can be done safely, effectively, and in a timely manner in elderly patients at specialized surgical teams. Advanced age alone should not be a limiting factor for the repair of paraesophageal hernias.
