Thoracoscopic plication for idiopathic eventration of the bilateral diaphragm: Report of a case

Introduction: Diaphragmatic eventration, defined as permanent elevation of the diaphragm without defects, is a rare anomaly in adults. Trauma, neoplasms, infection, and degenerative disease are the most common causes of this condition, whereas idiopathic eventration of the diaphragm is relatively infrequent. Presentation of case: We herein present the rare case of an 85-year-old female with idiopathic eventration of the bilateral diaphragm. The patient demonstrated a rapidly progressive course with dyspnea; therefore, thoracoscopic surgery of the unilateral diaphragm was performed. She subsequently withdrew from home oxygen therapy, which had introduced preoperatively, and exhibited a significant improvement in her pulmonary function for one year after the operation. Discussion: Various approaches for diaphragmatic plication have been reported, including open (transthoracic or transabdominal) and minimally invasive methods, such as thoracoscopic or laparoscopic plication. We consider thoracoscopic plication to be an effective minimally invasive method, although single-lung ventilation is required. Conclusion: We experienced a case in which thoracoscopic plication of the unilateral diaphragm resulted in adequate objective improvements in the pulmonary function in a patient with idiopathic eventration of the bilateral diaphragm

A case of mixed adenoneuroendocrine carcinoma (MANEC) arising in Barrett’s esophagus: literature and review

Abstract Background Mixed adenoneuroendocrine carcinoma (MANEC) is defined as a neoplasm composed of both exocrine and endocrine carcinomas, each comprising at least 30% of the tumor. MANEC can occur in various organs of the gastrointestinal tract, including the esophagus, stomach, and colon. We herein provide the first case report of surgically resected MANEC arising in Barrett’s esophagus (BE). Case presentation A 70-year-old man presenting with abdominal pain was referred to our hospital. Upper endoscopy showed a type 0-IIa + IIc elevated lesion adjacent to BE. According to a biopsy specimen, the elevated lesion was diagnosed as adenocarcinoma with neuroendocrine differentiation. No lymphatic or distant metastasis was detected in the preoperative examination. Laparoscopic distal esophagectomy and proximal gastrectomy were performed, and a diagnosis of MANEC in BE was determined according to the surgically resected specimen. Conclusions A very rare case of MANEC in BE was detected. BE can be the origin of esophageal MANEC as well as adenocarcinoma. Due to the small number of esophageal or esophagogastric MANEC cases reported, further accumulation of such cases is necessary to recommend an optimal management strategy for esophageal or esophagogastric MANEC
