ADENOCARCINOMA AND DYSPLASIA IN BARRETT ESOPHAGUS: CRITICAL ANALYSIS OF RISK FACTORS AND SURVEILLANCE PROTOCOLS.

Background: Identification of epidemiological risk factors in Barrett esophagus resulting in dysplasia and adenocarcinoma and its impact on prevention and early detection.

Aims: To evaluate epidemiological risk factors involved in the development of dysplasia and esophageal adenocarcinoma from Barrett esophagus in a specific population. To critically analyze the surveillance period, aiming to individualize follow-up time according to identified risks.

BRAZILIAN HERNIA AND ABDOMINAL WALL SOCIETY STATEMENT ON LARGE HIATAL HERNIAS MANAGEMENT.

Large hiatal hernias, besides being more prevalent in the elderly, have a different clinical presentation: less reflux, more mechanical symptoms, and a greater possibility of acute, life-threatening complications such as gastric volvulus, ischemia, and visceral mediastinal perforation. Thus, surgical indications are distinct from gastroesophageal reflux disease-related sliding hiatal hernias. Heartburn tends to be less intense, while symptoms of chest pain, cough, discomfort, and tiredness are reported more frequently.

MANAGEMENT OF SYMPTOMS RECURRENCE AFTER MYOTOMY FOR ACHALASIA. A PRACTICAL APPROACH.

Background: Achalasia is an esophageal motility disorder, and myotomy is one of the most used treatment techniques. However, symptom persistence or recurrence occurs in 9 to 20% of cases.

Aims: This study aims to provide a practical approach for managing the recurrence or persistence of achalasia symptoms after myotomy.

Advanced Cancer-A Bad Consequence of a Missed Follow-Up after ESD in Barrett's Esophagus.

Barrett's esophagus(BE)is a precursor to adenocarcinoma of the esophagogastric transition. Thus, endoscopic surveillance is essential for the early diagnosis of dysplasia and neoplasm, allowing proper therapeutic. However, during the COVID-19 pandemic, surveillance frequently failed.

Surgical management of esophageal stenosis due to ingestion of corrosive substances.

Background: Corrosive ingestion is a significant challenge for healthcare systems. Limited data are available regarding the best treatments, and there remains a lack of consensus about the optimal surgical approach and its outcomes. This study aims to review the current literature and show a single institution's experience regarding the surgical treatment of esophageal stenosis due to corrosive substance ingestion.

Preoperative botulinum toxin type A: A case report of a proposed new strategy for giant hiatal hernia management.

The use of preoperative ventral botulinum toxin for giant hiatal hernia management.

Does the nissen fundoplication procedure improve esophageal dysmotility in patients with barrett's esophagus?

Objective: to evaluate esophageal dysmotility (ED) and the extent of Barrett's esophagus (BE) before and after laparoscopic Nissen fundoplication (LNF) in patients previously diagnosed with BE and ED.

Methods: twenty-two patients with BE diagnosed by upper gastrointestinal (GI) endoscopy with biopsies and ED diagnosed by conventional esophageal manometry (CEM) were submitted to a LNF, and followed up with clinical evaluations, upper GI endoscopy with biopsies and CEM, for a minimum of 12 months after the surgical procedure.

Results: : sixteen patients were male (72.

Anti-reflux surgery for controlling respiratory symptoms of gastro-esophageal reflux disease: A systematic review and meta-analysis.

Gastro-esophageal reflux disease (GERD) patients have a higher prevalence of airway symptoms, such as chronic cough, wheezing, and hoarseness. The therapeutic management of patients with these symptoms is controversial. Therefore, this study aims to perform a systematic review and meta-analysis evaluating the efficacy of anti-reflux surgery for controlling respiratory symptoms related to GERD.

A case report of esophageal heterotopic pancreas presenting as recurrent mediastinal abscess, treated by minimally invasive esophagectomy.

Introduction: Heterotopic pancreas is a rare congenital anomaly. We report a case of esophageal heterotopic pancreas complicated by recurrent mediastinal abscess and treated by minimally invasive resection.

Presentation Of Case: A 31-year-old woman was admitted with a history of recurrent chest pain, dysphagia, and heartburn.

Prevalence of gallstones in 1,229 patients submitted to surgical laparoscopic treatment of GERD and esophageal achalasia: associated cholecystectomy was a safe procedure.

Background: Association between esophageal achalasia/ gastroesophageal reflux disease (GERD) and cholelithiasis is not clear. Epidemiological data are controversial due to different methodologies applied, the regional differences and the number of patients involved. Results of concomitant cholecistectomy associated to surgical treatment of both diseases regarding safety is poorly understood.

Improvement in quality-of-life after laparoscopic Nissen fundoplication.

Context: Evaluating quality of life after surgery for gastroesophageal reflux is fundamental, since improvement of symptoms is the main goal of treatment.

Objective: To compare the satisfaction of patients operated for GERD, interviewed at the office, with patients interviewed by telephone.

Methods: One hundred and seventy-eight patients were submitted to laparoscopic Nissen fundoplication.

Preoperative gastric acid secretion and the risk to develop Barrett's esophagus after esophagectomy for chagasic achalasia.

Introduction: The aim of this study was to determine the contribution of preoperative gastric secretory and hormonal response, to the appearance of Barrett's esophagus in the esophageal stump following subtotal esophagectomy.

Methods: Thirty-eight end-stage chagasic achalasia patients submitted to esophagectomy and cervical gastric pull-up were followed prospectively for a mean of 13.6 +/- 9.

Mucin pattern reflects the origin of the adenocarcinoma in Barrett's esophagus: a retrospective clinical and laboratorial study.

Background: Mucin immunoexpression in adenocarcinoma arising in Barrett's esophagus (BE) may indicate the carcinogenesis pathway. The aim of this study was to evaluate resected specimens of adenocarcinoma in BE for the pattern of mucins and to correlate to the histologic classification.

Methods: Specimens were retrospectively collected from thirteen patients who underwent esophageal resection due to adenocarcinoma in BE.

Barrett's esophagus (BE) and carcinoma in the esophageal stump (ES) after esophagectomy with gastric pull-up in achalasia patients: a study based on 10 years follow-up.

Background: Subtotal esophagectomy and gastric pull-up with cervical anastomosis is the main treatment for advanced achalasia. This surgical technique has been associated to esophagitis and also Barrett's epithelium following esophagectomy.

Aim: To analyze late clinical, endoscopic, and pathologic findings in the esophageal stump (ES) mucosa after subtotal esophagectomy in patients treated for advanced chagasic achalasia.

Origin of adenocarcinoma in Barrett's esophagus: p53 and Ki67 expression and histopathologic background.

Unlabelled: Barrett's esophagus is the substitution of squamous epithelium of the distal esophagus by columnar epithelium. Intestinal metaplasia in Barrett's esophagus is considered to be the main risk factor for the development of adenocarcinoma. Diffuse adenocarcinoma and Barrett's esophagus without intestinal metaplasia are rare, and reports on the subject are scarce.

Anatomic study of gastric vascularization and its relationship to cervical gastroplasty.

The aim of this study was to perform an anatomic study of the stomach and its vascularization, evaluating the frequency of communication between the right gastroepiploic artery (RGEA) and the left gastroepiploic artery (LGEA), as well as their relationship to the length of the stomach without extramural (direct) vascularization in cervical gastroplasty. Forty-two fresh human cadaveric specimens were studied, and the presence of communication between the RGEA and the LGEA was observed in 26 of the dissected stomachs (61.9%).
