Full-thickness resection method

1 . A full-thickness resection method for a gastrointestinal tract, wherein a stomach of the gastrointestinal tract is resected, the method comprising, in the following order:

forming a pair of first markings in surrounding tissue on both sides of a lesion to sandwich the lesion therebetween;

performing a full-thickness resection to a portion of the surrounding tissue along an incision line surrounding the lesion;

identifying a pair of first suture locations in the vicinity of the pair of first markings;

pulling together edges of a hole created by the full-thickness resection while suturing the pair of first suture locations, wherein the edges are captured and pulled together by grasping forceps that include a fixed forceps piece, a first forceps piece, and a second forceps piece, and the first forceps piece and the second forceps piece are independently rotatable on both sides of the fixed forceps piece; and

inflating the stomach with air.

2 . The full-thickness resection method according to claim 1 , wherein the pair of first markings are formed in the surrounding tissues on both sides of the lesion to sandwich a portion in the vicinity of a center of the lesion.

3 . The full-thickness resection method according to claim 1 , further comprising identifying a suture line for suturing a defect portion due to the full-thickness resection, wherein the pair of first markings are formed in the surrounding tissue on both sides to sandwich the suture line.

4 . The full-thickness resection method according to claim 3 , further comprising:

after the pair of first suture locations are sutured,

suturing a pair of second suture locations positioned on one side with respect to the pair of first suture locations in a direction along the suture line; and

suturing a pair of third suture locations positioned on the other side with respect to the pair of first suture locations in the direction along the suture line.

5 . The full-thickness resection method according to claim 4 , wherein a distance from the pair of first suture locations to the pair of third suture locations is substantially the same with a distance from the pair of first suture locations to the pair of second suture locations.

6 . A full-thickness resection method for a gastrointestinal tract, comprising, in the following order:

forming a pair of first markings in surrounding tissue on both sides of a lesion to sandwich the lesion therebetween, wherein the pair of first markings are formed at two points along a line perpendicular to a suture line;

forming a pair of end markings in the surrounding tissue on both sides of the lesion to sandwich the lesion therebetween, wherein the pair of end markings are formed at two points on either side of the suture line;

performing a full-thickness resection to a portion of the surrounding tissue along an incision line surrounding the lesion;

identifying a pair of first suture locations in the vicinity of the pair of first markings;

pulling together edges of a bole created by the full-thickness resection while suturing the pair of first suture locations;

pulling together the edges of the hole while suturing a pair of second suture locations positioned between the pair of first suture locations and one side of the pair of end markings; and

pulling together the edges of the hole while suturing a pair of third suture locations positioned between the pair of first suture locations and the other side of the pair of end markings,

wherein the edges of the hole are captured and pulled together by grasping forceps that include a fixed forceps piece, a first forceps piece, and a second forceps piece, and the first forceps piece and the second forceps piece are independently rotatable on both sides of the fixed forceps piece.

7 . The full-thickness resection method according to claim 6 , wherein the pair of first markings are different in shape from the pair of end markings.

8 . The full-thickness resection method according to claim 6 , further comprising:

identifying the suture line for suturing a defect portion due to the full-thickness resection,

wherein the pair of first markings are formed in the surrounding tissue on both sides to sandwich the suture line, and

the pair of end markings are formed in the surrounding tissue on one side and the other side of a direction along the suture line.

9 . The full-thickness resection method according to claim 6 ,

wherein the pair of first markings are formed in the surrounding tissue on both sides to sandwich a center of the lesion,

the pair of end markings are formed in the surrounding tissue on both sides to sandwich the center of the lesion, and

a first straight line passing through the pair of first markings intersects substantially perpendicularly with a second straight line passing through the pair of end markings.

10 . A full-thickness resection method for a gastrointestinal tract, comprising, in the following order:

identifying a suture line for suturing a defect portion due to the full-thickness resection;

forming a pair of first markings in surrounding tissue on both sides of a lesion to sandwich the lesion therebetween, wherein the pair of first markings are formed at two points along a first line perpendicular to the suture line;

forming a pair of second markings in the surrounding tissue on both sides to sandwich the suture line, wherein the pair of second markings are formed at two points along a second line perpendicular to the suture line;

forming a pair of third markings in the surrounding tissue on both sides to sandwich the suture line, wherein the pair of third markings are formed at two points along a third line perpendicular to the suture line;

performing a full-thickness resection to a portion of the surrounding tissue along an incision line surrounding the lesion;

identifying a pair of first suture locations in the vicinity of the pair of first markings;

pulling together edges of a bole created by the full thickness resection while suturing the pair of first suture locations;

identifying a pair of second suture locations in the vicinity of the pair of second markings;

pulling together the edges of the hole while suturing the pair of second suture locations;

identifying a pair of third suture locations in the vicinity of the pair of third markings; and

pulling together the edges of the hole while suturing the pair of third suture locations,

wherein the edges of the hole are captured and pulled together by grasping forceps that include a fixed forceps piece, a first forceps piece, and a second forceps piece, and the first forceps piece and the second forceps piece are independently rotatable on both sides of the fixed forceps piece.

11 . The full-thickness resection method according to claim 10 ,

wherein the pair of second markings are formed in the surrounding tissue on one side of the suture line with respect to the pair of first markings, and

the pair of third markings are formed in the surrounding tissue on the other side of the suture line with respect to the pair of first markings.

12 . The full-thickness resection method according to claim 11 , wherein a distance from the pair of first suture locations to the pair of third suture locations is substantially the same with a distance from the pair of first suture locations to the pair of second suture locations.
