Open Gastrostomy of a Gastric Leiomyoma Proximal to the Gastroesophageal Junction: A Case Report.

Gastric leiomyomas are benign, submucosal tumors found incidentally on unrelated imaging or during autopsy. The majority of leiomyomas are asymptomatic; however, patients can develop central ulcerations on the lesions leading to upper gastrointestinal (GI) bleeding. A 75-year-old female, with a past medical history of hypertension, hyperlipidemia, and a cerebrovascular accident, presented with complaints of melena, near-syncope events, lightheadedness, weakness, and hematemesis. A computed tomography (CT) of the abdomen with contrast found a heterogeneous low-attenuation mass of 4×4×3 cm3 within the gastric fundus and near the gastroesophageal (GE) junction. After an open gastrostomy and excisional biopsy, the mass was identified as a leiomyoma. This case report reviews the presentation, diagnostic assessments, and treatment of a gastric leiomyoma in a complex location proximal to the gastroesophageal junction. Gastric leiomyomas should be considered as a differential diagnosis for patients presenting with an upper gastrointestinal bleed.

Robotic Sigmoidectomy of a Rare Instance of Sigmoid Colon Duplication in an Elderly Patient: A Case Report.

Duplication of the alimentary tract is a rare malformation that can occur in any portion of the gastrointestinal tract. Rarely diagnosed in adulthood, it is usually an incidental finding due to non-specific gastrointestinal symptoms. Approximately 80% of cases are diagnosed in infants less than two years old. The most common location is the ileum, and the least common location is the rectum. Embryological theories discussing the etiology of alimentary tract duplications include failure of internal vacuolization during the sixth week of fetal development and/or the yolk-sac dorsal protrusion may adhere to the ectoderm during somite development. Environmental factors such as trauma or hypoxia affecting various intestinal fragments receiving blood supply can evolve into duplication. Excision with consideration to the common blood supply to protect the native bowel is the preferred treatment approach. We present the case of an elderly 70-year-old male with a bowel obstruction complicated by sigmoid duplication. After preoperative assessments, the patient underwent a robotic sigmoidectomy. This case report highlights colonic duplication as a differential diagnosis in the bowel obstruction of an elderly patient.
