ABSTRACT
BACKGROUND AND AIM:
Endoscopic submucosal dissection (ESD) enables complete, collective removal of gastrointestinal (GI) malignant tumors, but requires a long operation time. Air insufflated during ESD is distributed throughout the entire GI tract, and thus causes an enlarged feeling of the abdomen. We aimed to reduce the incidence of an enlarged feeling of the abdomen by wedging a balloon in the bulbus duodeni to reduce air flow into the lower parts of the GI tract.METHODS:
Sixteen patients who were approved by the institutional ethics committee and provided consent to participate in this single-center, prospective study were divided into two groups using a sealed-envelope randomizationmethod:
ESD with a balloon wedged in the bulbus duodeni (the balloon [+] group) or conventional ESD with no balloon (the balloon [-] group). Total air volume in the entire GI tract and its change before and after ESD were measured objectively by 3-D computed tomography.RESULTS:
In the balloon (+) group, the mean intestinal gas volume (± standard deviation) was 274.3 ± 142.0 mL before ESD, and 352.5 ± 183.2 mL after, with a mean change of 78.1 ± 139.7 mL. The increase in intestinal gas volume was well controlled. No postoperative complications, such as an enlarged feeling of the abdomen, was reported in the balloon (+) group.CONCLUSIONS:
Our new technique has several advantages, including reduction in the frequency of postoperative abdominal symptoms, and will be useful and safe for gastric ESD.
