Abstract:
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 grade Ⅰ obesity, 44 cases of grade Ⅱ obesity and 50 cases of grade Ⅲ obesity, 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 grade Ⅰ obesity. 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 grade Ⅱ obesity 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 grade Ⅲ obesity. 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 in obesity patients of different grades. All 139 patients were followed up at postoperative 3, 6 and 12 month. The total cholesterol (TC) were (4.5±0.9)mmol/L, (4.6±0.9)mmol/L, (4.3±0.8)mmol/L, (4.6±1.1)mmol/L at preoperative and postoperative 3, 6 and 12 month in cases of grade Ⅰ obesity. The above indicators were (4.5±0.8)mmol/L, (4.4±0.8)mmol/L, (4.4±1.0)mmol/L, (4.3±0.9)mmol/L in cases of grade Ⅱ obesity and (4.4±1.0)mmol/L, (4.7±1.1)mmol/L, (4.5±0.8)mmol/L, (4.4±0.5)mmol/L in cases of grade Ⅲ obesity. The above indicators among the three groups not meeting the mauchly′s test of sphericity ( χ2=20.81, P<0.05) and results of multi-variate test showed that there was no significant difference in the time effect, intergroup effect and interaction effect of TC among the three groups( Ftime=0.45, Fgroup=0.40, Finteraction=0.66, P>0.05). The triglyceride (TG) were (2.0±1.1)mmol/L, (1.3±0.4)mmol/L, (1.0±0.4)mmol/L, (1.0±0.4)mmol/L at preoperative and postoperative 3, 6 and 12 month in cases of grade Ⅰ obesity. The above indicators were (2.2±1.1)mmol/L, (1.5±0.5)mmol/L, (1.1±0.3)mmol/L, (1.0±0.3)mmol/L in cases of grade Ⅱ obesity and (2.3±1.1)mmol/L, (1.7±0.7)mmol/L, (1.4±0.6)mmol/L, (1.2±0.4)mmol/L in cases of grade Ⅲ obesity. The above indicators among the three groups not meeting the mauchly′s test of sphericity ( χ2=290.49, P<0.05) and results of multi-variate test showed that there were significant differences in the time effect, intergroup effect and interaction effect of TG among the three groups ( Ftime=80.44, Fgroup=4.13, Finteraction=2.67, P<0.05). The vitamin D were (12.9±5.9)μg/L, (16.5±5.9)μg/L, (18.0±6.3)μg/L, (20.1±5.7)μg/L at preoperative and postoperative 3, 6 and 12 month in cases of grade Ⅰ obesity. The above indicators were (11.5±4.4)μg/L, (17.1±5.0)μg/L, (18.2±5.6)μg/L, (20.2±6.6)μg/L in cases of grade Ⅱ obesity and (9.8±3.5)μg/L, (17.2±4.6)μg/L, (18.1±4.7)μg/L, (19.5±5.2)μg/L in cases of grade Ⅲ obesity. The above indicators among the three groups not meeting the mauchly′s test of sphericity ( χ2=53.07, P<0.05) and results of multi-variate test showed that there were significant differences in the time effect and interaction effect of vitamin D among the three groups ( Ftime=150.88, Finteraction=3.86, P<0.05)and there was no significant difference in the intergroup effect of vitamin D among the three groups ( Fgroup=0.35, P>0.05). (3) Body quality related indicators in obesity patients of different grades. The body mass and body mass index (BMI) were (88±8)kg, (71±8)kg, (65±8)kg, (61±7)kg, (32±2)kg/m 2, (26±2)kg/m 2, (24±2)kg/m 2, (22±2)kg/m 2 at preoperative and postoperative 3, 6 and 12 month in cases of grade Ⅰ obesity. The above indicators were (106±11)kg, (82±8)kg, (75±9)kg, (70±9)kg, (37±1)kg/m 2, (29±2)kg/m 2, (26±2)kg/m 2, (25±3)kg/m 2 in cases of grade Ⅱ obesity and (131±20)kg, (101±15)kg, (89±13)kg, (79±12)kg, (45±6)kg/m 2, (35±5)kg/m 2, (31±4)kg/m 2, (27±4)kg/m 2 in cases of grade Ⅲ obesity. The above indicators among the three groups not meeting the mauchly′s test of sphericity ( χ2=194.60, 179.52, P<0.05) and results of multi-variate test showed that there were significant differences in the time effect, intergroup effect and interaction effect of body mass and BMI among the three groups( Ftime=492.59, 543.86, Fgroup=89.13, 95.91, Finteraction=13.97, 13.32, P<0.05). The percen-tage of excess weight loss (EWL%) were 61%±16%,84%±21%,96%±23% at postoperative 3, 6 and 12 month in cases of grade Ⅰ obesity. The above indicators were 55%±7%,72%±16%,85%±19% in cases of grade Ⅱ obesity and 45%±12%,64%±15%,78%±7% in cases of grade Ⅲ obesity. The above indicators among the three groups not meeting the mauchly′s test of sphericity ( χ2=51.61, P<0.05) and results of multi-variate test showed that there were significant differences in the time effect and intergroup effect of EWL% among the three groups ( Ftime=374.52, Fgroup=15.69, P<0.05) and there was no significant difference in the interaction effect of EWL% among the three groups ( Finteraction=1.08, P>0.05). The percentage of total body weight loss (TWL%) were 19%±5%, 26%±6%, 30%±6% at postoperative 3, 6 and 12 month in cases of grade Ⅰ obesity. The above indicators were 21%±6%, 29%±6%, 34%±7% in cases of grade Ⅱ obesity and 22%±7%, 32%±7%, 39%±8% in cases of grade Ⅲ obesity. The above indicators among the three groups not meeting the mauchly′s test of sphericity ( χ2=58.54, P<0.05) and results of multi-variate test showed that there were significant differences in the time effect, intergroup effect and interaction effect of TWL% among the three groups ( Ftime=290.61, Fgroup=12.32, Finteraction=5.49, P<0.05). The waist to hip ratio (WHR) and visceral fat area (VFA) were 0.92±0.04, 0.86±0.03, 0.84±0.03, 0.83±0.03, (129±19)cm 2, (79±17)cm 2, (63±15)cm 2, (57±14)cm 2 at preoperative and postoperative 3, 6 and 12 month in cases of grade Ⅰ obesity. The above indi-cators were 0.98±0.05, 0.90±0.05, 0.87±0.05, 0.86±0.05, (169±20)cm 2, (105±23)cm 2, (85±20)cm 2, (73±20)cm 2 in cases of grade Ⅱ obesity and 1.05±0.09, 0.94±0.06, 0.91±0.06, 0.89±0.05, (218±42)cm 2, (144±35)cm 2, (114±26)cm 2, (96±19)cm 2 in cases of grade Ⅲ obesity. The above indicators among the three groups not meeting the mauchly′s test of sphericity ( χ2 =289.99, 191.92, P<0.05) and results of multi-variate test showed that there were significant differences in the time effect, intergroup effect and interaction effect of WHR and VFA among the three groups ( Ftime=361.39, 707.60, Fgroup=34.28, 12.69, Finteraction=8.31, 94.89, P<0.05). Conclusion:Treatment of obesity patients of different grades with LSG can improve patients′ TG and vitamin D levels, and reduce patients′ body mass, BMI, EWL%, TWL%, WHR and VFA.
