Leak test method for medical procedure via natural orifice

Abstract

A leak test method for a medical procedure via a natural orifice includes: inflating the abdominal cavity by introducing a gas into the abdominal cavity via a conduit inserted from the abdominal cavity after closing an opening that communicates between the inside of a hollow organ and the inside of the abdominal cavity using an instrument inserted via the patient's natural orifice; monitoring no leakage between the hollow organ and the abdominal cavity of a fluid passing through the closed opening; and removing the conduit inserted into the abdominal cavity once no leakage of the fluid has been confirmed.

Claims

1. A leak test method for a medical procedure via a natural orifice, comprising: inflating an abdominal cavity by introducing a gas into the abdominal cavity via a conduit inserted from the abdominal cavity after closing an opening that communicates between the inside of a hollow organ and the inside of the abdominal cavity using an instrument inserted via the patient's natural orifice;monitoring no leakage between the hollow organ and the abdominal cavity of a fluid passing through the closed opening; andremoving the conduit inserted into the abdominal cavity once no leakage of the fluid has been confirmed.

2. The method according to claim 1, wherein inflating the abdominal cavity comprises inserting an inflating needle having a conduit through an abdominal wall into the abdominal cavity.

3. The method according to claim 2, wherein monitoring comprises inserting an observation device via the natural orifice, and confirming the presence or absence of a flow of the fluid by the observation device.

4. The method according to claim 2, wherein monitoring comprises detecting a pressure inside the abdominal cavity via the inflating needle.

5. The method according to claim 1, wherein inflating the abdominal cavity comprises inserting an inflating needle having a conduit into the hollow organ via the natural orifice, and piercing the inflating needle into the abdominal cavity from inside the hollow organ.

6. The method according to claim 5, wherein monitoring comprises inserting the observation device via the natural orifice, and confirming the presence or absence of a flow of the fluid with the observation device.

7. The method according to claim 5, wherein monitoring comprises detecting a pressure inside the abdominal cavity via the inflating needle.

8. The method according to claim 1, wherein inflating the abdominal cavity comprises closing the opening with the tube while passing a tube through the opening in place, and supplying gas to the abdominal cavity from the tube.

9. The method according to claim 8, wherein monitoring comprises inserting the observation device via the natural orifice, and confirming the presence or absence of a flow of the fluid with the observation device.

10. The method according to claim 8, wherein monitoring comprises detecting a pressure inside the abdominal cavity via the inflating needle.

11. The method according to claim 1, further comprising supplying the fluid to the hollow organ having the closed opening.

12. The method according to claim 11, further comprising varying the body position of the patient so that the closed opening is submerged in the fluid.
