Neoadjuvant Chemoradiotherapy And Surgery Compared With Surgery Alone In Squamous Cell Carcinoma Of The Esophagus.
Despite progress in recent years in methods of diagnosis and surgical treatment of esophageal cancer, there is still controversy about the benefits from neoadjuvant chemoradiotherapy. To analise the survival of patients submitted to esophagectomy for squamous cell carcinoma of the esophagus with or without neoadjuvant chemoradiotherapy. A retrospective, non-randomized study conducted using the medical charts of patients operated for squamous cell carcinoma of the esophagus at the School of Medical Sciences, University of Campinas (UNICAMP), Campinas, São Paulo, Brazil between 1979 and 2006. The Kaplan-Meier analysis was used to calculate survival curves and the log-rank test to compare data in each group. The significance level was settled as 5%. A total of 123 patients were evaluated in this study, divided into three groups: I-26 (21.2%) patients submitted to esophagectomy alone; II-81 (65.8%) patients submitted to neoadjuvant radiotherapy plus esophagectomy and III-16 (13%) patients submitted to neoadjuvant chemoradiotherapy plus esophagectomy. A statistically significant survival was recorded between the groups (log rank=6.007; P=0.05), survival being greatest in the group submitted to neoadjuvant chemoradiotherapy, followed by the group submitted to neoadjuvant radiotherapy compared to the group submitted to esophagectomy alone as the initial treatment of choice. Radiotherapy and chemotherapy neoadjuvants in patients with squamous cell carcinoma of the esophagus offers benefits and increases survival.50101-
Gastric Adenocarcinoma After Gastric Bypass For Morbid Obesity: A Case Report And Review Of The Literature.
Gastric adenocarcinoma after gastric bypass for morbid obesity is rare but has been described. The diet restriction, weight loss, and difficult assessment of the bypassed stomach, after this procedure, hinder and delay its diagnosis. We present a 52-year-old man who underwent Roux-en-Y gastric bypass 2 years ago and whose previous upper digestive endoscopy was considered normal. He presented with weight loss, attributed to the procedure, and progressive dysphagia. Upper digestive endoscopy revealed stenosing tumor in gastric pouch whose biopsy showed diffuse-type gastric adenocarcinoma. He underwent total gastrectomy, left lobectomy, distal pancreatectomy and splenectomy, segmental colectomy, and bowel resection with esophagojejunal anastomosis. The histopathological analysis confirmed the presence of gastric cancer. The pathogenesis of gastric pouch adenocarcinoma is discussed with a literature review.201360972

Surgical gastrostomy: current indications and complications in a university hospital
OBJECTIVE: To analyze the surgical gastrostomies performed at a public University Hospital, their indications and complications. METHODS: We conducted a retrospective, nonrandomized review of medical records of patients who underwent surgical gastrostomy from 2007 to 2011; RESULTS: , In the period of studied, 86 patients underwent surgical gastrostomies for enteral nutrition. The Stamm technique was employed in all cases. Men constituted 76 (88%) of the cases and the mean age was 58.4 years, the maximum age being 87 years and the minimum 19. We observed 16 (18.60%) minor complications, 17 (19.76%) serious complications and 8 (9.3%) perioperative deaths. CONCLUSION: Surgical gastrostomy, while considered a smaller procedure, is not without complications and mortality. The Stamm technique, despite the complications reported, is easy to perform and to handle, as well as safe.OBJETIVO: revizar as indicações e as complicações observadas após a realização de gastrostomias cirúrgicas em pacientes internados em um hospital universitário público de ensino. MÉTODOS:estudo retrospectivo não randomizado de revisão dos prontuários médicos dos pacientes submetidos à gastrostomia cirúrgica nos últimos cinco anos, sobre as indicações e complicações. RESULTADOS: no período de 2007 a 2011, 86 pacientes foram submetidos à gastrostomias cirúrgicas para nutrição enteral. A técnica operatória utilizada foi a de Stamm na totalidade dos casos. Os homens constituíram 76 (88%) dos casos e a média de idade foi 58,4 anos, a idade máxima 87 anos e a mínima de 19 anos. Foram observadas 16 (18,60%) complicações consideradas menores, 17 (19,76%) complicações graves e oito (9,3%) óbitos peri-operatórios. CONCLUSÃO: as gastrostomias cirúrgicas, embora consideradas procedimentos de menor porte, não são isentas de complicações e mortalidade. A técnica operatória de Stamm, apesar das complicações relatadas, é de fácil execução, manuseio e oferece segurança.45846
Identification of preoperative risk factors for persistent postoperative dysphagia after laparoscopic antireflux surgery
BACKGROUND: Postoperative dysphagia is common after antireflux surgery and generally runs a self-limiting course. Nevertheless, part of these patients report long-term dysphagia. Inadequate surgical technique is a well documented cause of this result. AIM: This retrospective study evaluated the preoperative risk factors not surgery-related for persistent dysphagia after primary laparoscopic antireflux surgery. METHODS: Patients who underwent laparoscopic antireflux surgery by the modified technique of Nissen were evaluated in the preoperative period retrospectively. Postoperative severity of dysphagia was evaluated prospectively using a stantardized scale. Dysphagia after six weeks were defined as persistent. Statistical tests of association and logistic regression were used to identify risk factors associated with persistent dysphagia. RESULTS: A total of 55 patients underwent primary antireflux surgery by a single surgeon team. Of these, 25 patients had preoperative dysphagia (45,45%). Persistent postoperaive dysphagia was reported by 20 (36,36%). Ten patients (18,18%) required postoperative endoscopic dilatation for dysphagia. There was statistical association between satisfaction with surgery and postoperative dysphagia and requiring the use of antireflux medication after the procedure; and between preoperative dysphagia and postoperative dysphagia. Logistic regression identified significant preopertive dysphagia as risk factor for persistent postoperative dysphagia. No correlations were found with preoperative manometry. CONCLUSIONS: Patients with significant preoperative dysphagia were more likely to report persistent postoperative dysphagia. This study confirms that the current manometric criteria used to define esophageal dysmotility are not reliable to identify patients at risk for post-fundoplication dysphagia. Minucious review of the clinical history about the presence and intensity of preoperative dysphagia is important in the selection of candidates for antireflux surgery.RACIONAL: Disfagia no pós-operatório é comum após a operação anti-refluxo. No entanto, uma parte dos pacientes relatam disfagia persistente, e técnica cirúrgica inadequada é uma causa bem documentada deste resultado. OBJETIVO: Este estudo retrospectivo avaliou os fatores de risco no pré-operatório para a disfagia persistente após operação anti-refluxo por via laparoscópica. MÉTODOS: Pacientes submetidos à operação anti-refluxo por via laparoscópica pela técnica de Nissen modificada foram avaliados no pré-operatório de forma retrospectiva. A severidade da disfagia pós-operatória foi avaliada prospectivamente usando uma escala estabelecida. A disfagia após seis semanas foi definida como persistente. Os testes estatísticos de associação e regressão logística foram utilizados para identificar os fatores de risco associados à disfagia persistente. RESULTADOS: Um total de 55 pacientes foram submetidos ao procedimento por via laparoscópica por uma única equipe de cirurgiões. Destes, 25 doentes referiam disfagia pré-operatório (45,45%). A disfagia pós-operatória persistente foi relatada por 20 (36,36%) pacientes. Dez (18,18%) necessitaram de dilatações por endoscopia digestiva. Houve associação estatística entre a satisfação com a operação e disfagia no pós-operatório e exigindo o uso de medicação anti-refluxo após o procedimento, e entre disfagia no pré-operatório e disfagia no pós-operatório. A regressão logística identificou a disfagia no pré-operatório, como fator de risco para a disfagia pós-operatória persistente. Não foram observadas correlações com manometria pré-operatória. CONCLUSÕES: Os pacientes com disfagia no pré-operatório foram mais propensos a relatar disfagia pós-operatória persistente. Os critérios manométricos atuais utilizados para definir dismotilidade esofágica não identificaram pacientes com risco de disfagia persistente pós-fundoplicatura. Análise minuciosa da história clínica sobre a presença e intensidade da disfagia no pré-operatório é muito importante na seleção de candidatos à operação anti-refluxo.16516
ARE THERE ADVANTAGES IN DOUBLE TRANSIT RECONSTRUCTION AFTER TOTAL GASTRECTOMY IN PATIENTS WITH GASTRIC CANCER? A SYSTEMATIC REVIEW
ABSTRACT BACKGROUND: Curative treatment for gastric cancer involves tumor resection, followed by transit reconstruction, with Roux-en-Y being the main technique employed. To permit food transit to the duodenum, which is absent in Roux-en-Y, double transit reconstruction has been used, whose theoretical advantages seem to surpass the previous technique. AIMS: To compare the clinical evolution of gastric cancer patients who underwent total gastrectomy with Roux-en-Y and double tract reconstruction. METHODS: A systematic review was carried out on Web of Science, Scopus, EmbasE, SciELO, Virtual Health Library, PubMed, Cochrane, and Google Scholar databases. Data were collected until June 11, 2022. Observational studies or clinical trials evaluating patients submitted to double tract (DT) and Roux-en-Y (RY) reconstructions were included. There was no temporal or language restriction. Review articles, case reports, case series, and incomplete texts were excluded. The risk of bias was calculated using the Cochrane tool designed for randomized clinical trials. RESULTS: Four studies of good methodological quality were included, encompassing 209 participants. In the RY group, there was a greater reduction in food intake. In the DT group, the decrease in body mass index was less pronounced compared to preoperative values. CONCLUSIONS: The double tract reconstruction had better outcomes concerning body mass index and the time until starting a light diet; however, it did not present any advantages in relation to nutritional deficits, quality of life, and post-surgical complications
Retrospective study of results of neo-adjuvant therapy of esophgeal carcinoma in the survival of the operated patients in the College of Medicine of UNICAMP
Orientadores: Nelson Adami Andreollo, Luiz Roberto LopesDissertação (mestrado) - Universidade Estadual de Campinas, Faculdade de Ciências MédicasResumo: A neoplasia de esôfago é a oitava neoplasia mais incidente no Brasil, mantendo alta letalidade a despeito da melhora do tratamento cirúrgico nas últimas décadas. Os tratamentos utilizados dividem-se em: I) paliativos (sondas para nutrição enteral, próteses endoscópicas, gastrostomia, jejunostomia, derivação esôfago-gástrica, quimioterapia, radioterapia) e; II) curativos (esofagectomias isoladas, terapias neo-adjuvantes e terapias adjuvantes). Sendo assim, estratégias de tratamento neo-adjuvante tornam-se objeto de estudo. O objetivo do trabalho é avaliar em estudo retrospectivo não-randomizado a morbidade, a mortalidade e a sobrevida dos pacientes operados na Faculdade de Ciências Médicas da UNICAMP no período de 1979 a 2006, divididos em três grupos: I) esofagectomia; II) radioterapia neo-adjuvante seguido de esofagectomia; e III) radioterapia-quimioterapia neo-adjuvante seguido de esofagectomia. Na análise dos resultados, os grupos não diferem significativamente quanto ao sexo, cor, idade, alguns sintomas pré-operatórios (pirose, tabagismo), complicações pós-operatórias, mortalidade, N patológico, grau de diferenciação histológica e estadiamento; os grupos diferem significativamente em relação a outros sintomas (disfagia, dor retroesternal, etilismo), localização tumoral, T patológico e resposta tumoral. As conclusões mostram diferenças de sobrevida entre os grupos após a exclusão dos óbitos peri-operatórios, com benefício estatisticamente significativo para a terapêutica neo-adjuvanteAbstract: Neoplasm of esophagus cancer is the eighth highest incidence in Brazil, maintaining a high mortality rate despite the improvement of surgical treatment in recent decades. Treatments are divided into: I) palliative (nasogastric tube for enteral nutrition, prosthetics, endoscopic gastrostomy, jejunostomy, esophageal-gastric bypass, chemotherapy, radiotherapy) and; II) radical (esophagectomy isolated, neo-adjuvant therapy and adjuvant therapy) . Thus, neoadjuvant treatment strategies become the object of study. The objective is to evaluate with a non-randomized retrospective study morbidity, mortality and survival of patients operated in the Faculty of Medical Sciences of Campinas in the period 1979-2006, divided into three groups: I) esophagectomy; II) neoadjuvant radiotherapy followed by esophagectomy, and III) neoadjuvant radiotherapy and chemotherapy followed by esophagectomy. Results show that groups did not differ significantly regarding gender, race, age, some preoperative symptoms (heartburn, smoking), postoperative complications, mortality, N pathological, histological grade and stage; groups differ significantly for other symptoms (dysphagia, retrosternal pain, alcoholism), tumor location, T and pathological tumor response. Findings show differences in survival between groups after the exclusion of perioperative deaths, with statistically significant benefit for neoadjuvant therapyMestradoCirurgiaMestre em Cirurgi
