NCT03629808

Brief Summary

This is a prospective cohort study, which subjects were obese patients requiring LSG surgery. LSG with different gastric resection starting points (2-4cm/4-6 cm from pylorus) as intervention method. The main observation is the incidence and extent of upper gastrointestinal symptoms (such as nausea, vomiting, retching, reflux, difficulty swallowing, etc.).In addition, secondary observations include the excess weight loss (%EWL) and postoperative complications. Aim to investigate the effects of LSG surgery in different starting points of gastric resection on postoperative upper gastrointestinal symptoms.

Outcome Measures

Primary Outcomes (1)

  • The incidence rate of upper gastrointestinal symptoms after surgery

    We use three scales to evaluate the incidence of upper gastrointestinal symptoms,include the Chinese translation of R-INVR(the Index of Nausea, Vomiting, and Retching)、EAT-10(Validity and Reliability of the Eating Assessment Tool) and GIS(GERD impact serve).These three scales describe postoperative upper gastrointestinal symptoms,which include vomiting, dysphagia,and acid reflux,heartburn.We focus on the incidence rate of the above symptoms in one year after surgery during 1 year. Visit: Post-op 12 months Visit(±7 Days)

    1 year after surgery

Secondary Outcomes (3)

  • The excess weight loss (%EWL) after surgery

    1 year after surgery

  • the rate of postoperative complications after surgery

    1 year after surgery

  • The extent of upper gastrointestinal symptoms after surgery

    1 year after surgery

Study Arms (2)

Group1: 4-6cm

4-6cm from starting point of gastrectomy to pylorus
