Peroral endoscopic myotomy in a pregnant woman diagnosed with mitochondrial disease: A case report.

Background: Achalasia is a primary esophageal motility disease characterized by impairment of normal esophageal peristalsis and absence of relaxation of the lower esophageal sphincter. Sometimes is can be a part of some genetic disorders. One of the causes of gastrointestinal motility disorders, including achalasia, is mitochondrial defects.

Submucosal Tunneling Muscle Biopsy for Esophageal Motility Disorders: A Case Report.

Submucosal tunneling endoscopic technique can be useful in obtaining esophageal muscle specimens in patients with esophageal motility disorders. Here, we describe the case of a patient with systemic sclerosis. Histological verification of the esophageal involvement in the pathological process was required for the treatment.

Splenectomy following JAK1/JAK2 inhibitor therapy in patients with myelofibrosis undergoing allogeneic stem cell transplantation.

Background: Allogeneic hematopoietic stem cell transplantation (alloHSCT) is the only treatment option with curative potential in patients with myelofibrosis (MF). The aim of our study was to evaluate the safety of splenectomy before alloHSCT in MF patients who failed to achieve significant spleen response after ruxolitinib therapy.

Methods: Splenectomy was performed in 12 patients for alloHSCT with myelofibrosis-primary (6 patients), post-polycythemia vera (3 patients).
