Objectives
Narrative objectives1 Overlap esophagojejunostomy (OEJ) in laparoscopic total gastrectomy (LTG) is one of the gastrointestinal reconstruction methods that can be performed for safe and complete laparoscopic surgery using a linear stapler after LTG. OEJ is considered to be an excellent esophageal jejunal anastomosis method because there are very few reports of anastomotic leakage and stenosis, and it can be used even when the esophageal resection length is long. However, during long-term observation of patients undergoing OEJ after LTG, patients may experience passage obstruction due to bending of the elevated jejunum near the esophageal hiatus without anastomotic stenosis. As a general rule, this complication requires re-operation to relieve the stenosis, but there have been no reports of passage obstruction in OEJ without the anastomotic stenosis. Therefore, by extracting patients who have developed this complication and analyzing the patient factors, clinicopathological factors, perioperative factors, surgical findings, in detail, the characteristics of treatment and prevention of this complication can be identified. The purpose is to clarify.

Key inclusion criteria From April 2009 to May 2020, patients who underwent laparoscopic total gastrectomy for gastric cancer at Saga University Hospital in department of Surgery and underwent esophagojejunostomy using the Overlap method.
Among them, patients who had an obstruction of passage in the elevated jejunum due to flexion at the anastomotic site of the esophagus and jejunum.
Key exclusion criteria Patients who are out of regular surveillance.
Patients who required intrathoracic OEJ through a thoracoscopic approach because they required excision of over 4 cm of esophagus.
Target sample size 5

Other
Other related information From April 2009 to May 2020, in department of Surgery at Saga University Hospital, targeting gastric cancer who underwent LTG and OEJ, reoperation was required due to passage obstruction due to flexion at the esophageal jejunum anastomosis. We will extract the patients who have undergone surgery, analyze their patient factors, clinicopathological factors, perioperative factors, surgical findings, etc., and clarify the characteristics of treatment and prevention of this complication.
