## Abstract

Provided is a digestive-tract treatment method including: pulling, inside a digestive tract (A), an end portion of a first wall portion (A1) positioned at a rim of a treatment target site (B), and moving the first wall portion (A1) to a position on a second wall portion (A2) on an opposite side of the treatment target site (B) from the first wall portion (A1); and joining the first wall portion (A1) and the second wall portion (A2) in a state in which the first wall portion (A1) and the second wall portion (A2) are layered.

## Claims

### Claim 1

A digestive-tract treatment method comprising:
pulling, inside a digestive tract, an end portion of a first wall portion positioned at a rim of a treatment target site and a third wall portion, which forms the treatment target site, and moving the first wall portion to a position on a second wall portion on an opposite side of the treatment target site from the first wall portion such that the first wall portion is placed along the second wall portion, the first wall portion being positioned on an opposite side of the treatment target site from the anus, the second wall portion being positioned closer to the anus than the treatment target site;
joining the first wall portion and the second wall portion in a state in which the first wall portion and the second wall portion are layered, and
subsequent to the joining, cutting at least a portion of the first wall portion and the third wall portion between a position at which the first wall portion and the second wall portion are joined and the end portion of the first wall portion.

### Claim 2 (depends on 1)

The digestive-tract treatment method according to claim 1,
wherein pulling comprises pulling the first wall portion until the second wall portion is folded back,
the joining comprises joining the second wall portion and the first wall portion in a state in which the second wall portion, which has formed two layers by being folded back, and the first wall portion are layered, and
the cutting comprises excising the entire third wall portion.

### Claim 3 (depends on 1)

The digestive-tract treatment method according to claim 1, wherein the joining comprises suturing the first wall portion and the second wall portion.

### Claim 4 (depends on 1)

The digestive-tract treatment method according claim 1,
wherein the digestive tract is the colon, and
the treatment target site is a diverticulum.

### Claim 5 (depends on 4)

The digestive-tract treatment method according to claim 4, wherein the first wall portion and the second wall portion are joined with a portion of the diverticulum interposed therebetween.

### Claim 6

A treatment method of a colon, the method comprising:
grabbing a first wall portion of the colon at a first position relative to a rim around a treatment target site;
pulling the first wall portion beyond a second wall portion of the colon in a direction of an anus, the second wall portion being at a second position relative to the rim around the treatment target site, the second position being closer to the anus than the first position;
moving the first wall portion in the direction of the anus until the treatment target site is closer to the anus than the second position; and
subsequent to the moving, joining the first wall portion and the second wall portion in a state in which the first wall portion and the second wall portion are layered.

### Claim 7 (depends on 6)

The treatment method according to claim 6, wherein the first position is at the rim.

### Claim 8 (depends on 6)

The treatment method according to claim 6, wherein the second position is at the rim.

### Claim 9

A digestive-tract treatment method comprising:
pulling, inside a digestive tract, an end portion of a first wall portion positioned at a rim of a treatment target site, and moving the first wall portion to a position on a second wall portion on an opposite side of the treatment target site from the first wall portion;
joining the first wall portion and the second wall portion in a state in which the first wall portion and the second wall portion are layered; and
subsequent to the joining, cutting at least a portion of the first wall portion and a portion between the first wall portion and a third wall portion, which forms the treatment target site, between a position at which the first wall portion and the second wall portion are joined and the end portion of the first wall portion.

### Claim 10 (depends on 9)

The digestive-tract treatment method according to claim 9,
wherein the digestive tract is the colon,
the treatment target site is a tumor, and
wherein the pulling comprises pulling the first wall portion until the second wall portion is folded back,
the joining comprises joining the second wall portion and the first wall portion in a state in which the second wall portion, which has formed two layers by being folded back, and the first wall portion are layered, and
the cutting comprises excising the tumor from the colon.
