Abstract

Non-parasitic splenic cysts are a rare pathology whose incidence seems to be increasing due to incidental diagnosis by abdominal imaging tests. Cysts larger than 5cm are susceptible to hemorrhage, rupture and infection and must be treated surgically, even when asymptomatic. Although Laparoscopic Splenectomy has already proven to be safe, feasible and effective, its use in cases of massive splenomegaly remains controversial. Case reports from the last decade show that laparotomy remains a widely used access route for the treatment of giant splenic cysts. The objective of this study is to evaluate the safety and efficacy of Laparoscopic Splenectomy in the treatment of patients with non-parasitic giant splenic cyst in a tertiary hospital. A retrospective clinical study will be carried out through the analysis of medical records of patients with giant non-parasitic splenic cyst treated with Laparoscopic Splenectomy at HC/FMUSP over a period of 15 years (2005 to 2020). In our service, there are about 30 cases of non-parasitic giant splenic cysts treated exclusively by laparoscopy that can be included in the study. The following data will be collected: age, gender, comorbidities (ASA), cause of splenic disease, symptoms, changes in physical examination, laboratory tests (hemogram and tumor markers) and imaging tests (computerized tomography of total/upper abdomen with contrast and Total abdomen USG), intraoperative finding, associated procedures performed, conversion rate, clinical and surgical complications in the postoperative period, blood transfusions, surgical complications in a period of less than 30 days, surgical time, anatomopathological description of the surgical specimen ( measurement and weight), reoperations and length of hospital stay.
