Abstract
Unilateral diaphragmatic paralysis is a disorder in which one side of the diaphragm loses the capacity to contract to allow for adequate inspiration. The majority of patients suffering from unilateral diaphragmatic paralysis are asymptomatic and do not require treatment. The laparoscopic sleeve gastrectomy (LSG) is the most common bariatric surgical operation. In this case report, I present the case of a 36-year-old male with congenital left hemidiaphragm paralysis who had LSG for the treatment of morbid obesity. This case demonstrates the efficacy and feasibility of LSG in patients with asymptomatic hemidiaphragm paralysis. During surgery, surgeons must pay close attention to a variety of factors, including a stomach fundus that is situated high in a subcostal region with a narrow space to work.
