Gastrin: a new branch of the gastropancreatic axis that can explain the effect of sleeve gastrectomy on glucose metabolism.

Background: Among bariatric techniques, sleeve gastrectomy (SG) stands out owing to its efficiency. The role of the stomach as a secretory organ of many substances, such as gastrin, related to insulin secretion is well known. Gastrin induces insulin release in isolated pancreatic islets, limiting somatostatin-14 intraislet release, and has been associated with blood glucose level improvement in diabetic models after SG.

Lymphoepithelial cyst of the pancreas.

Within pancreatic cysts, the lymphoepithelial variant is considered a highly atypical condition with few reported cases in the literature. Following a case managed in our hospital, we aim to shed more light on this entity as an incidental finding, providing a temporal description until its excision, along with radiological, surgical, and histological images.

Partial splenectomy for a giant epidermoid cyst of the spleen.

The splenic epidermoid cysts are rare benign tumors, and a definitive treatment remains unclear. Although some spleen-preserving approaches have been reportedly used, splenic cyst recurrence usually occurs in true cyst cases, wherein the cyst is incompletely removed. In our case, partial splenectomy was performed and the giant cyst was completely removed.

Superior mesenteric artery syndrome in a patient with Charcot Marie Tooth disease.

The extrinsic compression of the third part of the duodenum as it passes through the aorto-mesenteric angle is known as the superior mesenteric artery syndrome (SMAS). This syndrome is a rare mechanical cause of upper intestinal obstruction, with a reported incidence of between 0.2% and 0.

Real anal leiomyoma: a case report.

Leiomyoma of the rectum and anal canal is an unusual benign mesenchymal neoplasm that originates from smooth muscle cells. We describe the clinical presentation, MRI findings, and surgical treatment of a rare case of perianal leiomyoma confirmed by immunohistochemistry. We also report a review of the world's literature on the subject.

Uterine leiomyosarcoma metastasis to the pancreas: report of a case and review of the literature.

Introduction: Uterine leiomyosarcoma is an aggressive malignant tumor that often leads to metastatic dissemination, generally in the lungs, liver, brain, and bones. Despite the fact that pancreatic neoplasms spread easily, the pancreas is not a usual target organ from other neoplasms.

Case Report: We present a rare case of metastasis to the pancreas from uterine leiomyosarcoma treated with segmental resection with no recurrence at this stage.

Intraabdominal bronchogenic cyst.

Introduction: Bronchogenic cyst is pathology of the respiratory track. It consists of a defect during the embryological development of the tracheobronchial tree. Most common presentation is as a solid or cystic mass located in mediastinum, and it is usually diagnosed in relation to respiratory problems or recurrent infections in children.
