A comprehensive intervention strategy, ie. multi sector cooperation, community participation and integration of hospital, school, community and family, etc, has been put forward to promote the health and sustainable development of adolescents.

Objective: To investigate the clinical application value of symmetrical three-hole laparoscopic sleeve gastrectomy (LSG). Methods: The retrospective and descriptive study was conducted. The clinical data of 232 patients with obesity who were admitted to Zhengzhou Central Hospital Affiliated to Zhengzhou University from April 2017 to December 2018 were collected. There were 40 males and 192 females, aged (32±8)years, with a range of 17-63 years. All the 232 patients underwent symmetrical three-hole LSG. Observation indicators: (1) surgical and postoperative conditions; (2) complications; (3) follow-up. Follow-up was conducted by telephone interview and WeChat to collect the patient satisfaction with cosmetic effects of wounds at 3 months after surgery up to March 2019. Measurement data with normal distribution were expressed as Mean±SD. Count data were expressed as absolute numbers or percentages. Results: (1) Surgical and postoperative conditions: of the 232 patients, 230 underwent symmetrical three-hole LSG successfully, without conversion to open surgery. Two patients had one puncture hole added due to spleen bleeding to help pull the omentum to stop bleeding, and no spleen hemorrhage recurred after improving the surgical procedure. Of the 232 patients, the operation time, volume of intraoperative blood loss, and duration of postoperative hospital stay were (115±7)minutes, (10±5)mL, and (3.0±0.8)days. (2) Complications: of the 232 patients, 10 had postoperative complications of fat liquefaction in the umbilical incision, and were cured after repeated dressing changes. All patients had no serious complications such as gastrointestinal bleeding, abdominal bleeding, or gastric fistula. (3) Follow-up: of the 232 patients, 230 undergoing successful symmetrical three-hole LSG were followed up for 3 months. Of the 230 patients, 3 were dissatisfied with the cosmetic effects of wounds, 12 were satisfied, and 215 were very satisfied. The satisfaction rate was 98.70%(227/230). Conclusion Symmetrical three-hole LSG is safe and feasible, with a good cosmetic effects of wounds.
