Cholecystitis treatment via gallbladder occlusion or sealing
A method comprises obstructing at least a portion of an inside of a gallbladder using a barrier, and suppressing, using the barrier, contacting at least a portion of an interior wall of the gallbladder with a bile from a cystic duct.
1 . A method comprising:
obstructing at least a portion of an inside of a gallbladder using a barrier; and
suppressing, using the barrier, contacting at least a portion of an interior wall of the gallbladder with a bile from a cystic duct, wherein the barrier comprises a bag configured to cover an interior of the gallbladder, the bag having an opening.
2 . The method according to claim 1 , comprising draining a bile from the gallbladder before the obstructing, wherein the draining comprises:
transporting bile from the gallbladder via a tube placed at least partially within the cystic duct.
3 . The method according to claim 2 , wherein the draining further comprises:
advancing a guidewire, via an endoscope having a distal portion located in a duodenum, from a duodenal papilla to the gallbladder, and
placing a tube at least partially within the cystic duct using the guidewire.
4 . The method according to claim 2 , comprising draining a bile from a gallbladder before the obstructing, wherein the draining comprises:
advancing a needle into the gallbladder through a duodenum via an endoscope having a distal portion located in the duodenum;
advancing a guidewire from the endoscope to the gallbladder using the needle;
retracting the needle into the endoscope; and
placing a tube from the duodenum to the gallbladder using the guidewire.
5 . The method according to claim 1 , wherein the obstructing at least a portion of an inside of the gallbladder using a barrier comprises:
advancing a catheter and the barrier from an endoscope to the gallbladder through a duodenal papilla;
retracting the catheter to expose the barrier.
6 . The method according to claim 1 , wherein the barrier further comprises:
a ring fixed to the opening.
7 . The method of claim 6 , comprising attaching the ring to at least one of an inside of a cystic duct and an inside of the gallbladder.
8 . The method according to claim 1 , wherein the obstructing comprises:
applying an adhesive to an inside of the gallbladder.
9 . A method of cholecystitis treatment, comprising:
a removal step of removing contents of a gallbladder;
a bile suppression step of arranging a member in the gallbladder, wherein the member is a sack; and
a sealing step of closing a gap between the member and the gallbladder, or between the member and a cystic duct.
10 . The method of cholecystitis treatment according to claim 9 , wherein
the member is inflatable, and
in the sealing step, the gap is closed by contact between the inflated member and the gallbladder, or the inflated member and the cystic duct.
11 . The method of cholecystitis treatment according to claim 10 , wherein in the sealing step, the gap between an opening of the sack and the gallbladder, or between an opening of the sack and the cystic duct is closed.
12 . The method of cholecystitis treatment according to claim 11 , wherein the sealing step comprises joining between the opening and the gallbladder, or between the opening and the cystic duct.
13 . The method of cholecystitis treatment according to claim 11 , wherein the sealing step comprises placing a stent in the opening.
14 . The method of cholecystitis treatment according to claim 9 , wherein, the member is introduced into the gallbladder using a guide wire inserted into a bile duct from the gallbladder and protruding from a duodenal papilla as a guide.
