Colonoscopy was performed using attached transparent hoods (D-201–12704 and D-201–13404; Olympus Medical Systems, Tokyo, Japan). MoviPrep (EA Pharma Co., Tokyo, Japan) laxative was used for bowel preparation. Either scopolamine butylbromide (10 mg) or glucagon (0.5 mg) was used. Furthermore, midazolam (1–4 mg) was used for conscious sedation only when the patient complained of abdominal discomfort or pain. The colonoscope used in this study was EC-L600ZP7 using the LASEREO 7000 system (Fujifilm Co.). The CAD EYE (EW10-EC02) endoscopic real-time diagnostic support function (Fujifilm Co.) was used to support lesion detection.
Colon cleansing quality was graded as poor, fair, or good according to the criteria reported by Aronchick et al.

Check if the same lab product or an alternative is used in the 5 most similar protocols

ESD procedure was performed using a dual knife or hook knife (KD-650, KD-620, respectively; Olympus, Tokyo, Japan ), or a combination of the above through a 2-channel scope equipped with multibending and water jet functions (GIF-2TQ260M; Olympus Optical). A soft transparent hood (D-201-13404; Olympus, Tokyo, Japan) was attached to the tip of the endoscope to obtain good endoscopic views of the submucosal layer. Marking dots were placed on the normal mucosa at approximately 5 mm from the tumor margin to provide safety margins. After submucosal injection of glycerol (10 % glycerol and 5 % fructose; Chugai Pharmaceutical, Tokyo, Japan) with a small amount of indigo carmine and 0.1 % epinephrine, a mucosal incision was made outside the marking dots. Hyaluronic acid solution was added to the injection solution when mucosal elevation was insufficient due to ulceration of the lesion or massive fibrosis of the submucosal layer 13 (link)
14 (link). After mucosal incision, dissection of the submucosal layer was performed and en bloc resection was able to be achieved completely. The resected specimen was cut into 4-mm-thick slices after formalin fixation. The histological type, size, depth of invasion, lateral and vertical margins, and lymphatic-vascular invasion were evaluated in each slice according to the Japanese Classification of Gastric Carcinoma 3 .

In EHS, a double-channeled multibending scope (GIF-2TQ260M, GIF-H290T; Olympus, Tokyo, Japan) was used. A transparent straight hood (D-201–13404, D-201–11804; Olympus) was mounted on the tip of the endoscope for the optimal endoscopic view. V-loc absorbable barbed sutures (VLOCL0604, VLOCM0804; Covidien, Mansfield, Massachusetts, United States) were manipulated with a prototype of the flexible needle holder, which was commercially launched later as the SutuArt (FG-260L, FG-260Q; Olympus). After delivering the suture and grasping the needle at half to one-third from the tail, the first stitch was generally placed on the distal side from the endoscope, followed by suturing toward the proximal side. Suturing was provided at 5- to 10-mm intervals and at approximately 8 mm of the suture bites. A mucosal defect was closed by mucosal suturing, and a full-thickness defect was made by full-layer, double-layer, or single-layer suturing depending on the situation. After suturing, the remnant suture with the needle was cut with the scissor forceps (FS-410L, FS-410U; Olympus) and retrieved. Details of the procedure have been described previously elsewhere

Endoscopic Treatment for Colonic Diverticular Bleeding

Check if the same lab product or an alternative is used in the 5 most similar protocols

Considering the general condition of the patients, the operators decided to perform bowel preparation using either polyethylene glycol or an enema, and in some cases, no specific bowel preparation was performed. In most cases colonoscopy was performed using a PCF-Q260JI or PCF-H290I scope (Olympus Medical Systems, Tokyo, Japan). Other scopes (CF-Q260AI, PCF-H290Z, PCF-H290TI, or PCF-PQ260L, Olympus Medical Systems; EC-590MP, FUJIFILM, Saitama, Japan) were also used for colonoscopy. The scope was used with a soft cap (D201-10704, D201-11804, D201-12704, or D201-13404; Olympus Medical Systems) and water jet device in all colonoscopies. Endoscopic treatment for CDB with SRH was performed at the discretion of the individual operators. Clipping was predominantly conducted using hemoclips (HX-610-135S or HX-610-135, Olympus Medical Systems; ROCC-D-26-195-C, Micro-Tech, Nanjing, China). These hemoclips were used for the so-called direct method (Fig. 2d), where they were placed on the vessel as close to the bleeding as possible (23 (link)). In contrast, indirect clipping was performed in the Zipper fashion when either the source of the bleeding could not be confirmed due to massive bleeding or it was difficult to insert the clip into the diverticulum (23 (link)).
