RESUMO

RESUMEN La resección gástrica atípica ha demostrado ser beneficiosa para tumores submucosos. La técnica pre senta mayor riesgo cuando estos se desarrollan próximos a la unión esófago-gástrica (UEG). Para esta limitación se propuso la resección intragástrica mediante una técnica mixta combinando laparoscopia y endoscopia. En nuestro medio no existen publicaciones al respecto. Se trata de una mujer de 42 años, con lesión subepitelial-subcardial de 2 cm, evaluada mediante videoendoscopia alta (VEDA), compa tible con tumor del estroma gastrointestinal (GIST) evaluado mediante ecoendoscopia. La lesión fue resecada mediante abordaje combinado laparoendoscópico. Bajo visión laparoscópica se introdujeron en cavidad abdominal trocares con balón, y bajo visión endoscópica intragástrica se introdujeron estos en el estómago y se fijó la pared gástrica a la pared abdominal insuflando dichos balones. Posterior mente se realizó la resección de la lesión con sutura mecánica. El abordaje combinado es seguro y eficaz, simple en manos entrenadas, pero constituye una opción reproducible en casos seleccionados.

ABSTRACT Atypical gastric resection has proved to be beneficial to treat submucosal tumors. The technique is more difficult when these tumors develop next to the gastroesophageal junction (GEJ). Intragastric resection combining endoscopic and laparoscopic approach was proposed to solve this limitation. There are no publications about this technique in our environment. A 42-year-old female patients with a 2-mm subepithelial tumor below the cardia evaluated by upper gastrointestinal (UGI) videoendoscopy and endoscopic ultrasound suggestive of a gastrointestinal stroma tumor (GIST) underwent resection using the combined laparo-endoscopic approach. Under laparoscopic guidance, balloon-tipped trocars were introduced in the abdominal cavity and then into the stomach using endoscopic view. The balloons were inflated to fix the gastirc wall to the abdominal wall. The lesion was resected using mechanical stapler. The combined approach is safe and efficient, and simple to perform for trained professionals, constituting a reproducible option in selected cases.

RESUMO

INTRODUCTION: The purpose of this study was to conduct a retrospective study about the clinical effects of endoscopic mucosal dissection on the treatment of early esophagogastric precancerous lesions. METHODS: A total of 132 patients with early esophagogastric precancerous lesions who were diagnosed and treated with concurrent surgery in our hospital from January 2018 to December 2019 were included in this retrospective study. Patients were divided into endoscopic mucosal resection (EMR) group (n = 58) and endoscopic submucosal dissection (ESD) group (n = 74) according to different surgical methods. The data in the two groups were compared and analyzed in terms of surgical indicators, treatment status and incidence of postoperative complications. RESULTS: There were statistically significant differences between the two groups in the whole block cutting rate, fractional cutting rate and complete cutting rate (P < 0.05). The mean operation time of ESD group was significantly longer than that of EMR group (P < 0.05). There were no significant differences in the intraoperative bleeding rate, blood loss, average specimen area, length of hospital stay and treatment cost between the two groups (P > 0.05). The incidence and recurrence of postoperative complications, including bleeding, perforation and stenosis in the two groups, were observed within 1 year of postoperative follow-up. The incidence of complications in ESD group was slightly higher than that in EMR group, and the local recurrence rate in ESD group was lower than that in EMR group (P > 0.05). CONCLUSION: ESD is an alternative surgical treatment for patients with early esophagogastric precancerous lesions.

RESUMO

ABSTRACT CONTEXT: Non-islet-cell-tumor-induced hypoglycemia (NICTH) is caused on rare occasions by secretion of insulin from tumor cells that are reported to have a single tissue origin. CASE REPORT: A 67-year-old male patient had cardia adenocarcinoma and concomitant lung adenocarcinoma with extensive metastases and repeated episodes of intractable hypoglycemia. Immunohistochemical staining for insulin showed that lung adenocarcinoma stained positive and gastric cardia adenocarcinoma stained weakly positive. These results indicate that tumor cells of different tissue origins co-secreted insulin. CONCLUSIONS: This is the first report on intractable hypoglycemia due to co-secretion of insulin from two kinds of primary tumor cells in a single patient.

RESUMO

Almost 10% of patients with Crest syndrome associated with severe gastroesophageal reflux and 5-10% of patients with failed cardiomyotomy for achalasia present with cardial or distal esophageal organic stricture. Some of these cases are poor risk patients for surgery and therefore the surgeon must offer a safe procedure with low morbimortality, keeping in mind the pathophysiological motor pattern of these patients.In order to treat the stricture to improve the esophageal transit we treated patients with esophagocardioplasty associated with vagotomy-antrectomy and Roux-en-Y gastrojejunostomy, thereby avoiding the potential acid or biliary reflux in poor risk patients in whom esophagectomy would be a very deleterious procedure. All four patients had a good postoperative evolution and late control demonstrated good esophagogastric transit with no postoperative esophagitis.

RESUMO

INTRODUCTION: Recurrence of achalasia may occur in 10%-20% of cases operated by Heller's cardiomyotomy. Most of these patients will require further surgery to relieve symptoms. Major technical difficulties can be found in these reoperations. CASE REPORT: A 50-year-old female patient with relapsed idiopathic achalasia after Heller's technique was treated with an unusual procedure, for the first time in the literature, by minimally invasive access with robotic assistance. CONCLUSIONS: The Serra-Doria operation allows preserving the esophagus and alleviating dysphagic symptoms with low rates of postoperative complications. The use of robotic technology is perfectly feasible and allows minimally invasive access in complex cases and reoperations.

RESUMO

ABSTRACT Background Since Chagas disease has esophageal manifestations with different degrees of involvement, the best surgical option is controversial, especially for patients with advanced chagasic megaesophagus and recurrent symptoms after previous treatment. Objective To assess the early and late outcomes of esophagocardioplasty in a series of patients with advanced recurrent chagasic megaesophagus. Methods This descriptive study included 19 older patients with recurrent megaesophagus grade III/IV and positive immunofluorescence for Chagas disease. They had undergone cardiomyotomy with anterior fundoplication a mean of 16.5 years ago. Serra-Doria esophagocardioplasty was selected to treat the recurrence. The patients were followed to assess postoperative and late complications and the incidence of symptom recurrence. Results In early assessment, five (26.3%) patients presented clinical complications. One (5.2%) patient had a gastrointestinal fistula secondary to esophagogastric anastomotic leak, which responded well to conservative treatment. In the one-year follow-up, 18 (94.7%) patients could swallow normally and had no vomiting. Three years after surgery, 10 (62.5%) of 16 patients could swallow normally, and 3 (19.3%) patients complained of vomiting. Five years after surgery, only 5 (38.4%) of 13 patients could swallow normally and 7 (53.8%) had vomiting. Conclusion Serra-Doria esophagocardioplasty for the treatment of advanced recurrent megaesophagus had mild postoperative complications and good success rate in the short-term follow-up. In the long-term follow-up, it proved to be a poor surgery choice because of the high incidence of symptom recurrence, compromising quality of life. This procedure should be indicated only for patients with advanced recurrent megaesophagus without clinical conditions to undergo esophageal resection.

RESUMO Contexto A doença de Chagas, por apresentar manifestações esofágicas com diferentes graus de acometimento, faz com que haja controvérsias quanto a melhor opção cirúrgica; principalmente para pacientes com megaesôfago chagásico avançado e com recidiva de sintomas após tratamento prévio. Objetivo Avaliar o resultado precoce e tardio da esofagocardioplastia em uma série de pacientes com megaesôfago chagásico avançado e recidivado. Métodos Estudo descritivo, com 19 pacientes idosos com megaesôfago Grau III/IV recidivado e com imunoflorescência positiva para doença de Chagas. A cirurgia prévia foi a cardiomiotomia com fundoplicatura anterior, com tempo médio de realização de 16,5 anos. A cirurgia de eleição para o tratamento da recidiva foi a esofagocardioplastia de Serra-Dória. Realizou-se avaliação precoce para estudar as complicações pós-operatórias e tardias, para avaliar a incidência de recidiva de sintomas. Resultados Na avaliação precoce, 5 (26,3%) pacientes apresentaram complicações clínicas. Um (5,2%) paciente apresentou fístula digestiva consequente a deiscência da anastomose esofagogástrica, mas com boa evolução com o tratamento conservador. Na avaliação de 1 ano de pós-operatório, 18 (94,7%) pacientes apresentavam deglutição normal e sem regurgitação. Com 3 anos de pós-operatório, de 16 pacientes analisados; 10 (62,5%) pacientes apresentavam deglutição normal e 3 (19,3%) se queixavam de regurgitação. Com 5 anos de pós-operatório, de 13 pacientes analisados; somente 5 (38,4%) apresentavam deglutição normal e 7 (53.8%) com regurgitação. Conclusão A esofagocardioplastia de Serra-Dória, no tratamento cirúrgico do megaesôfago avançado recidivado, apresentou complicações pós-operatórias de baixa morbidade e com boa resolutividade, na avaliação precoce. Na avaliação de longo prazo, demonstrou não ser um procedimento cirúrgico adequado, pela alta incidência de recidiva de sintomas, com comprometimento da qualidade de vida. Deve ser indicada somente em pacientes com doença avançada recidivada, sem condições clínicas de serem submetidas à ressecção esofágica.

RESUMO

OBJECTIVE: Globally, gastric cancer incidence shows remarkable international variation and demonstrates distinct characteristics by the two major topographical subsites, cardia (CGC) and non-cardia (NCGC). Because global incidence estimates by subsite are lacking, we aimed to describe the worldwide incidence patterns of CGC and NCGC separately. DESIGN: Using Cancer Incidence in Five Continents Volume X (CI5X), we ascertained the proportions of CGC and NCGC by country, sex and age group (<65 and ≥65 years). These derived proportions were applied to GLOBOCAN 2012 data to estimate country-specific age-standardised CGC and NCGC incidence rates (ASR). Regional proportions were used to estimate rates for countries not included in CI5X. RESULTS: According to our estimates, in 2012, there were 260,000 cases of CGC (ASR 3.3 per 100,000) and 691,000 cases of NCGC (ASR 8.8) worldwide. The highest regional rates of both gastric cancer subsites were in Eastern/Southeastern Asia (in men, ASRs: 8.7 and 21.7 for CGC and NCGC, respectively). In most countries NCGC occurred more frequently than CGC with an average ratio of 2:1; however, in some populations where NCGC incidence rates were lower than the global average, CGC rates were similar or higher than NCGC rates. Men had higher rates than women for both subsites but particularly for CGC (male-to-female ratio 3:1). CONCLUSIONS: This study has, for the first time, quantified global incidence patterns of CGC and NCGC providing new insights into the global burden of these cancers. Country-specific estimates are provided; however, these should be interpreted with caution. This work will support future investigations across populations.
