The clinical data of 84 patients were analyzed retrospectively. LSG was performed in 84 patients. The preoperative and intraoperative conditions were recorded.Analyze the relevant factors of the volume, so as to evaluate the measurement method. The RGV measured by us was significantly correlated with body weight and BMI, and was most closely correlated with body weight (r = 0.367); it was also correlated with gender, three-dimensional, blood lipid and other indicators. The measurement method of volume of stomach in vitro (Gas-liquid combined measurement method) during LSG operation is of high feasibility and objective authenticity. The measurement method of volume of stomach in vitro (Gas-liquid combined measurement method) during LSG operation is of high feasibility and objective authenticity. The presentation of leak after laparoscopic sleeve gastrectomy (LSG) is variable. A missed or delayed diagnosis can lead to severe consequences. This study presents our experience the clinical presentations, laboratory, and radiological findings in patients with leak after LSG. A retrospective review of patients who were diagnosed and treated as leak after LSG at our center (January 2012-November 2019). Eighty patients developed leak 68 (85%) after primary LSG, 6 (7.5%) after Re-LSG and 6 (7.5%) after band removal to revisional LSG. Mean age 35.9 ± 10years. The diagnosis was within 18 ± 14days after surgery. Five (6.3%) patients were diagnosed during the same admission. Only 29.3% of patients were diagnosed correctly from the first visit to the ER. Most were misdiagnosed as gastritis (49%) and pneumonia (22.6%). Thirty-four patients (45.3%) were diagnosed correctly at the third visit. The most common presenting symptoms were abdominal p
