Objective To investigate the clinical efficacy of laparoscopic sleeve gastrectomy(LSG)in obesity patients of different grades.Methods The retrospective and descriptive study was conducted.The clinical data of 139 obesity patients of different grades who were admitted to the General Hospital of Ningxia Medical University from January 2018 to December 2021 were collected.There were 37 males and 102 females,aged(32±9)years.Of the 139 patients,there were 45 cases of gradeⅠobesity,44 cases of gradeⅡobesity and 50 cases of gradeⅢobesity,respectively.Obser-vation indicators:(1)intraoperative and postoperative situations in obesity patients of different grades;(2)hematological related indicators in obesity patients of different grades;(3)body quality related indicators in obesity patients of different grades.Measurement data with normal distribution were represented as Mean±SD,and comparison within three groups was conducted using the One-way Anova test and comparison between groups was conducted using the LSD test.Measurement data with skewed distribution were represented as M(range),and comparison within three groups was conducted using the Kruskal-Wallis H test.Count data were described as absolute numbers,and comparison between groups was performed using the chi-square test or Fisher exact probability.Repeated measurement data were analyzed by the repeated ANOVA.Results(1)Intraoperative and postoperative situations in obesity patients of different grades.The operation time,volume of intraoperative blood loss,duration of postoperative hospital stay and cases readmitted within 30 days after surgery were 2.0(range,1.5-2.0)hours,50(range,50-100)mL,5(range,4-6)days and 2 in the 45 cases of gradeⅠobesity.The above indicators were 2.0(range,1.5-2.0)hours,60(range,50-187)mL,5(range,4-6)days and 4 in the 44 cases of gradeⅡobesity and 2.0(range,1.5-2.1)hours,60(range,50-135)mL,5(range,4-7)days and 4 in the 50 cases of gradeⅢobesity.There was no significant difference in the operation time,volume of intraoperative blood loss,duration of postoperative hospital stay among the three groups of patients(H=4.11,0.77,3.59,P>0.05)and there was no significant difference in cases readmitted within 30 days after surgery among the three groups of patients(P>0.05).(2)Hematological related indicators
