Case report: The safety of laparoscopic surgery for the retroperitoneal bronchogenic cyst

Abstract

IntroductionBronchogenic cyst is a congenital aberration of bronchopulmonary malformation with bronchial-type, pseudostratified cylindrical epithelium. They are usually discovered in the mediastinum and intrapulmonary but are rarely encountered in retroperitoneum. We report a case of the retroperitoneal bronchogenic cyst and perform a literature review to summarize the safety of laparoscopic resection for this rare disease.Case presentationWe report a 57-year-old woman who was admitted to our hospital with no clinical symptoms and was found by chance to have masses in the adrenal gland area during a routine physical examination. An abdominal CT examination revealed a cystic lesion was found in the left suprarenal region. Afterward, the patient underwent a laparoscopic exploration. Histopathological findings confirmed the diagnosis of a retroperitoneal bronchogenic cyst. The patient recovered uneventfully without signs of recurrence during a 1-year follow-up period.ConclusionBronchogenic cyst is rare in the retroperitoneal region. It should be considered as one of the differential diagnoses of a retroperitoneal neoplasm, especially in the left retroperitoneal region. Laparoscopic surgery is technically feasible and safe for the treatment of patients with a retroperitoneal bronchogenic cyst.

Exploring the Temporal Variation of the Solar Quadrupole Moment J 2

“…Recent 3D simulations (Kitiashvili et al 2022) supported by observations have shown that the rotational effects in solar subsurface convection produce the formation of rotational shear and meridional circulation at midlatitudes. The structure of this near subsurface layer is "not uniform but contains a sharp shear layer in the top ≈8 Mm," which has been identified as a leptocline (see also Li et al 2022) in which radial variations of the differential rotation occurs, contributing obviously to more complex rotational laws.…”
