title: Single port intra-gastric full thickness resection: Using "Rotation and Revolution Single Instrument Tie (RRSIT)".
abstract: OBJECTIVE
  Recently, minimize incisions has led to a reduction in the number of ports, and has led to transumbilical single-port surgery. We evaluated the treatment result of single-port, intragastric, full thickness resections for gastric SMTs. In addition, we introduce a novel intracorporeal knot tying method.
  
  
  METHODS
  From August 2010 to March 2011, five patients underwent single-port intragastric, full thickness gastric wedge resections. After performing a gastrostomy, a single port was inserted into the stomach. After full thickness resection, the defect in the gastric wall was sutured by full thickness interrupted suture and a new knot tying technique.
  
  
  RESULTS
  The mean operative time was 129 ± 21.0 min and the mean mass size was 3.0±0.6 cm. There were two very low-risk GISTs, 2 leiomyomas, and 1 carcinoid. The post-operative course was uneventful in all patients. The mean hospital stay was 7.2±1.2 days.
  
  
  CONCLUSIONS
  Single-port intra-gastric full thickness resection with novel intracorporeal knot tying method is feasible and safe. novel intracorporeal knot tying method is a very useful knot tying method. We expect the application of novel intracorporeal knot tying method to be diverse and broad.
