Background
/Aims: Argon plasma coagulation (APC) is the most commonly used endoscopic treatment for gastric antral vascular ectasia (GAVE). Endoscopic band ligation (EBL) has emerged as an alternative therapy. Our goal was to evaluate the feasibility, efficacy, and safety of APC and EBL for the treatment of GAVE. This is the first systematic review that included only randomized controlled trials (RCTs) on this topic.
Methods
A comprehensive search was performed using electronic databases to identify RCTs comparing APC and EBL for the treatment of GAVE following the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines.
Results
Four RCTs were included, with a total of 204 patients. EBL was related to higher endoscopic eradication rates risk difference [RD], 0.29; 95% confidence interval [CI] [0.14, 0.44]; I²=0%) and less bleeding recurrence than APC (RD, 0.29; 95% CI [0.15, 0.44]; I²=0%). Patients treated with EBL required fewer blood transfusions (mean difference [MD], 1.49; 95% CI [0.28, 2.71]; I²=96%) and hospitalizations (MD, 0.29; 95% CI [0.19, 0.39]; I²=0%). The number of sessions required for the obliteration of lesions was higher with APC. There was no difference in the incidence of adverse events.
Conclusions
EBL is superior to APC in the treatment of GAVE in terms of endoscopic eradication rates, recurrence of bleeding, and transfusion requirements.

Background
/Aims: Gastric antral vascular ectasia (GAVE) is a rare acquired vascular lesion of the gastric antrum. The most frequent presentation of GAVE is iron deficiency anemia. Endoscopic therapy is the mainstay of treatment. However, there is no consensus regarding the optimal treatment modality.
Methods
A retrospective cohort study was performed on patients with GAVE, including patients receiving endoscopic therapy. Treatment was with either argon plasma coagulation (APC) or endoscopic band ligation (EBL). Basic demographic data, indication for index procedure, number of sessions, and pre- and post-hemoglobin levels were collected. The aim of the study was to compare outcomes across the two treatment modalities.
Results
One hundred and seventeen diagnoses of GAVE were made. Sixty-two patients (53%) required endoscopic treatment for symptomatic GAVE (female, n=38, 61%; mean age of 74.4 years). Two hundred and eighteen procedures were performed during the study period. APC was performed (n=161, 74%) more frequently than EBL (n=57, 26%). Patients treated with APC at index required a median 5 subsequent therapeutic interventions (APC or EBL), while those treated with EBL at index required a further 2.9 treatments (EBL only) (p<0.05).
Conclusions
APC was the most common treatment modality employed. We demonstrate an increasing incidence of EBL. Patients treated with EBL at index treatment required fewer subsequent treatment sessions and had a greater mean rise in hemoglobin. This suggests a more effective endoscopic response with EBL.

Removal of Esophageal Variceal Bands to Salvage Complete Esophageal Obstruction: Ala’ A Abdel Jalil, Ghassan Hammoud, Jamal A Ibdah, Sami Samiullah; Clin Endosc 2018;51(5):491-494. Published online August 21, 2018; DOI: https://doi.org/10.5946/ce.2018.011

Abstract PDF PubReader ePub: Esophageal varices develop in almost half of the patients with cirrhosis, and variceal hemorrhage constitutes an ominous sign with an increased risk of mortality. Variceal banding is considered an effective and mostly safe measure for primary and secondary prophylaxis. Although adverse events related to banding including dysphagia, stricture formation, bleeding, and ligation-induced ulcers have been described, complete esophageal obstruction is rare, with only 10 reported cases in the literature. Among those cases, 6 were managed conservatively; 1 patient had esophageal intraluminal dissection from an attempt to remove the bands using biopsy forceps but ultimately recovered with conservative management. Three patients developed strictures following removal of the bands, requiring repeated sessions of dilation therapy. We report on a patient who developed absolute dysphagia and complete esophageal obstruction after variceal banding. We successfully used the endoloop cutter hook to release the bands intact and restore luminal integrity.

Abstract PDF PubReader ePub

Endoscopic closure techniques have been introduced for the repair of duodenal wall perforations that occur during endoscopic retrograde cholangiopancreatography (ERCP). We report a case of successful repair of a large duodenal wall perforation by using double endoscopic band ligation (EBL) and an endoclip. Lateral duodenal wall perforation occurred during ERCP in a 93-year-old woman with acute calculous cholangitis. We switched to a forward endoscope that had a transparent band apparatus. A 2.0-cm ovalshaped perforation was found at the lateral duodenal wall. We repaired the perforation by sequentially performing double EBL and endoclipping. The first EBL was performed at the proximal edge of the perforation orifice, and two-thirds of the perforation were repaired. The second EBL, which also included the contents covered under the first EBL, repaired the defect almost completely. Finally, to account for the possible presence of a residual perforation, an endoclip was applied at the distal end of the perforation. The detection and closure of the perforation were completed within 10 minutes. We suggest that double EBL is an effective method for closure.

Abstract PDF PubReader ePub

Background
/Aims: Endoscopic band ligation (EBL) is an accepted method in the management of variceal bleeding; however, there is little evidence on the safety and feasibility of EBL for the closure of bowel perforation. In this study, we aimed to evaluate the technical feasibility and efficacy of EBL in iatrogenic colon perforation by using a canine model.
Methods
We established an iatrogenic colon perforation model by using seven beagle dogs. Longitudinal 1.5- to 1.7-cm colon perforations were created with a needle knife and an insulated-tip knife, and the perforation was subsequently closed with EBL. During a 2-week follow-up period, the animals were carefully monitored and then euthanized for pathologic examination.
Results
The EBL of iatrogenic colon perforations was successful in all dogs. The mean procedure time for EBL closure with one to three bands was 191.7 seconds, and there were no immediate complications. One animal was euthanized after 3 days because of peritonitis. There were no clinical and laboratory features of sepsis or peritonitis in the remaining six animals. On necropsy, we did not find any fecal peritonitis, pericolonic abscess formation, or transmural dehiscence at the perforation site. Histopathology demonstrated inflamed granulation tissue and scar lesions replaced by fibrosis.
Conclusions
EBL might be a feasible and safe method for the management of iatrogenic colon perforations in an in vivo model.

Tips and Tricks for Better Endoscopic Treatment of Colorectal Tumors: Usefulness of Cap and Band in Colorectal Endoscopic Mucosal Resection: Seun Ja Park; Clin Endosc 2013;46(5):492-494. Published online September 30, 2013; DOI: https://doi.org/10.5946/ce.2013.46.5.492

Abstract PDF PubReader ePub

Endoscopic mucosal resection (EMR) is an endoscopic alternative to surgical resection of mucosal and submucosal neoplastic lesions. Prior to the development of knives, EMR could be performed with accessories to elevate the lesion. After the development of various knives, en bloc resection was possible without other accessories. So, recently, simple snaring without suction or endoscopic submucosal dissection using knife in the epithelial lesions such as adenoma or early mucosal cancer has been performed. However, for easy and complete resection of subepithelial lesions such as carcinoid tumor, a few accessories are needed. Complete resection of rectal carcinoid tumors is difficult to achieve with conventional endoscopic resection techniques because these tumors often extend into the submucosa. The rate of positive resection margin for tumor is lower in the group of EMR using a cap (EMR-C) or EMR with a ligation device (EMR-L) than conventional EMR group. EMR-C and EMR-L (or endoscopic submucosal resection with a ligation device) may be a superior method to conventional EMR for removing small rectal carcinoid tumors.

Three Cases of Endoscopic Mucosal Resection of Rectal Carcinoid Tumor by Band Ligation and the Snare Resection Technique: Young Hwa Jo, M.D., Ji Hun Roh, M.D., Dong Young Goo, M.D., Jae Hoon Yoo, M.D., Ki Soo Kim, M.D., Young Min Shin, M.D., Sung Hoon Kim, M.D. and Ji Eun Park, M.D.; Korean J Gastrointest Endosc 2010;41(1):45-51. Published online July 31, 2010

Abstract PDF: Many reports have shown that endoscopic polypectomy or endoscopic mucosal resection can successfully remove tumor less than 1.0 cm in size. However, most carcinoid tumors in the rectum occur in the submucosal layer so that the entire tumor cannot be completely removed via endoscopic polypectomy or endoscopic mucosal resection. Endoscopic mucosal resection can also cause perforation of the intestinal wall and bleeding. Due to these reasons, instead of these two conventional methods, endoscopic mucosal resection using a ligation device is currently being used for the treatment of rectal carcinoid tumor. Recent studies that used this method have reported that endoscopic mucosal resection of rectal carcinoid tumor by band ligation and the snare resection technique is safe with minimal complications and this is quite useful to completely remove rectal carcinoid tumor.

Intramural Hematoma of the Esophagus after Endoscopic Pinch Biopsy and Endoscopic Band Ligation: Jae Nam Yang, M.D., Yun Jeong Lim, M.D., Ji Hun Kang, M.D., Hyoun Woo Kang, M.D., Jun Kyu Lee, M.D., Yong Seok Lee, M.D.*, Jong Sun Choi, M.D.^† and Jin Ho Lee, M.D.; Korean J Gastrointest Endosc 2010;40(2):107-110. Published online February 27, 2010

Abstract PDF: Esophageal intramural hematoma (EIH) is an uncommon clinical entity among the acute esophageal injuries, and EIH predominantly occurs in middle-aged women. The pathogenesis of EIH has not been clarified, yet this. Seems to occur within the submucosal layer of the esophagus after dissection of the mucosa. EIH may occur spontaneously or secondary to trauma. Patients usually complain of a sudden onset of severe retrosternal chest pain, hematemesis, back pain or dysphagia. Most EIHs show improvement through conservative management, including fasting and intravenous hydration, and this usually completely recovers within a period of 2∼3 weeks. We report here on a case that EIH occurred after endoscopic pinch biopsy and endoscopic band ligation and this EIH was exacerbated in a patient who was taking long-term aspirin medication.

Endoscopic Treatment with Band Ligation and Electrocoagulation for Non-Variceal, Non-Ulcer Upper Gastrointestinal Bleeding: Hwa Min Kim, M.D., Yang Suh Ku, M.D., Moon Gi Chung, M.D., Young Nam Kim, M.D., Do Yoon Lim, M.D., Kwang An Kwon, M.D., Dong Kyun Park, M.D., Sun Suk Kim, M.D., Yeon Suk Kim, M.D., So Young Kwon, M.D., Yu Kyung Kim, M.D., Duck Joo Choi, M.D. and Ju Hyun K; Korean J Gastrointest Endosc 2006;33(2):69-76. Published online August 30, 2006

Abstract PDF: Background
/Aims: This study compared the therapeutic efficacy of endoscopic band ligation (EBL) with that of electrocoagulation for treating non-variceal, non-ulcer (NVNU) upper gastrointestinal (UGI) bleeding. Methods: This study included 89 patients who underwent EBL and 56 patients in whom monopolar electrocoagulation was performed for NVNU UGI bleeding. The lesions treated were Mallory-Weiss tear in 91 patients, Dieulafoy's lesion in 42 patients and angiodysplasia in 12 patients. Results: The initial hemostatic rate was 97% in the EBL group and 91% in the electrocoagulation group, but this was not statistically different. Rebleeding occurred in 5 of 89 patients (5.6%) in the EBL group and in 8 of 56 patients (14.3%) in the electrocoagulation group (p=0.07). Thrombocytopenia or prothrombin time prolongation was confirmed to be a significant risk factor for rebleeding. The rebleeding rate in the high risk group was significantly lower than in the EBL group (9% vs. 30%, respectively, p=0.03). The median procedure time was significantly shorter in the EBL group compared with that in the electrocoagulation group (median 5.6 minutes vs. 8.3 minutes, respectively, p=0.04). Conclusions: EBL and electrocoagulation are both effective for treating NVNU UGI bleeding, and EBL is especially safe and effective for the cases with a high risk for rebleeding.

Published online August 30, 2004

Abstract PDF: Dieulafoy's lesion is a relatively uncommon disease which is minor cause of massive acute lower gastrointestinal bleeding. The lesion comprises mainly of an abnormally exposed submucosal artery associated with a minute mucosal defect on the top in the stomach, and it is a rare cause of profuse but intermittent gastrointestinal bleeding. Less commonly, similar lesions have also been identified in the duodenum, jejunum, colon, and in rare cases, the rectum. In this report, 70 year-old man is described, who has an massive hematochezia from a small rectal mucosal defect with an exposed vessel. Control of the bleeding was successfully achieved with endoscopic band ligation. The fact that rectal Dieulafoy's disease is rare but one of the causes of massive hematochezia should serve as a reminder in the future cases in the elderly.

Abstract PDF: Endoscopic band ligation has been a standard therapy in esophageal varix bleeding since it was first introduced in 1980s. However, technical problems have interrupted as a therapeutic management of lower gastrointestinal bleeding. We report a case of successful management of rectal bleeding with endoscopic band ligation in patient with chronic renal failure, who had been managed by hemodialysis since eight months before. Successful control of rectal bleeding was achieved by endoscopic band ligation. Three days later, round and shallow ulcer developed at the ligated site, which was improved at follow-up sigmoidoscopy and bleeding was not observed any more. He was discharged without complications. Herein, we report the band ligation as a useful method in treatment of rectal bleeding. (Korean J Gastrointest Endosc 2001;22:229⁣232)

Abstract PDF: Background
/Aims: There is no consensus as to the best treatment for non-variceal, non-ulcer gastrointestinal hemorrhage. Endoscopic band ligation is an inexpensive, readily available, and easily learned technique in contrast to conventional thermal methods of endoscopic hemostasis. The purpose of this study is to define the effectiveness of endoscopic band ligation for non-variceal, non-ulcer gas- trointestinal hemorrhage and post-polypectomy hemorrhage. Methods: Twenty eight patients were treated by band ligation between July 1996 and October 2000. The lesions treated were; Dieulafoy’s lesion in 13, Mallory-Weiss tear in 7, angiodysplasia in 1, post-polypectomy bleeding in 4, post-endoscopic mucosal resection bleeding in 2, post- endoscopic biopsy bleeding in I. Results: Endoscopic band ligation was successful in 25 of 28 cases. Additional sclerotherapy was necessary in two cases of Dieulafoy’s lesion. The remaining case was early band detachment. Conclusions: Endoscopic band ligation is effective for non-variceal, non-ulcer bleeding. It has the advantage of ease of use and is relatively inexpensive.

Abstract PDF: Although various endoscopic treatments, such as laser photocoagulation, electrocoagulation, heater probe, injection have been used for treatment of arteriovenous malformation (AVM), associated complications also have been reported. In order to avoid the complications, elastic band ligation has recently been used as an alternative method for endoscopic treatment of gastric AVM. A 58-year-old man was admitted due to hematemesis and melena. A gastroscopy revealed AVM with vessel exposure and active bleeding at the greater curvature of fundus, and we performed arteriography for emergency embolization, but, we do not find the bleeding vessel. Endoscopic band ligation therapy was performed as an alternative method for control of bleeding. 2 months later, follow-up endoscopy showed disappearance of AVM and no evidence of hemorrhage.

Abstract PDF: Background
/Aims: The Dieulafoy's lesion is an unusual cause of massive gastrointestinal bleeding resulting from the erosion of an abnormally large submucosal artery. Surgical intervention was believed to be the best treatment in the past, but recently improvement of endoscopic techniques has made effective hemostasis possible in most cases of Dieulafoy's lesions. Therapeutic endoscopic hemostasis includes sclerotherapy, electrocauterization, laser coagulotherapy, clipping band ligation. The effectiveness of the endoscopic band ligation was evaluated in bleeding Dieulafoy's lesions. Methods: Clinical characteristics, initial endoscopic findings, and effectiveness of band ligation in Dieulafoy's lesions were all analyzed. Results: 1) The patients were 8 males and 1 female, and the mean age was 56.2 years. 2) The chief complaints were melena and hematemesis, and 2 cases had histories of recurrent gastrointestinal bleeding. 3) The diagnosis of Dieulafoy's lesion was possible in 7 of 9 patients (78%) at the initial endoscopy. 4) The lesions were mostly located in the fundus and the body, characterized mainly by protruding vessels in shallow erosion areas. 5) The initial band ligation was possible with successful hemostasis, but additional sclerotherapy was necessary in two cases. There were no complications related to the procedure, except a case of early band detachment. Conclusions: The Dieulafoy's lesion requires careful endoscopic observation for diagnosis, and endoscopic band ligation was an effective therapeutic option for bleeding Dieulafoy's lesions.

증례 : 식도 위장관 ; 내시경적 결찰요법에 의한 상부위장관출혈 치유 3예 ( Case Reports : Esophagus , Stomach & Intestine ; Endoscopic Ligation Therapy for Upper Gastrointestinal Bleeding ): Korean J Gastrointest Endosc 1998;18(3):345-351. Published online November 30, 1997

Abstract PDF: Upper gastrointestinal bleeding occurs so rapidly that emergency measures are required to avoid exsanguination. Many diseases cause bleeding from the gastrointestinal tract. Patients with upper gastrointestinal bleeding must be quickly assessed and resuscitated. An endoscopy is the diagnostic procedure of choice because of its high rate of accuracy and immediate therapeutic potential. An endoscopy however, must be performed only following adequate resuscitation and clinical assessment of the patient. Recently, reports have described the usefulness of endoscopic O-ring band ligation in the management of upper gastrointestinal bleeding. Endoscopic O-ring band ligation is mucosal ligation using intraluminal negative pressure with an elastic O-ring. We performed an emergency endoscopy in 3 patients who had massive or recurrent episodes of upper gastrointestinal bleeding, identified as having resulted from Dieulafoy lesion and Anisakiasis. We tried to perform an endoscopic ligation using an O-ring band, and were successful in achieving hemostasis. Our conclusion is that endoscopic ligation using an O-ring band can be used effectively to control active upper gastrointestinal bleeding resulting from Anisakiasis and a Dieulafoy lesion.

원저 : 식도 위장관 ; O형 고무 밴드 결찰법을 이용한 Mallory - Weiss 증후군의 치료 ( Original Articles : Esophagus , Stomach & Intestine ; Management of Mallory - Weiss Syndrome by 0-ring Band Ligation ): Korean J Gastrointest Endosc 1998;18(2):152-160. Published online November 30, 1997

Abstract PDF: Background
/Aims: Mallory-Weiss syndrome refers to a laceration or lacerations in the region of the gastroesophageal junction due to vomiting, retching, or coughing induced by several causes, and preceding hematemesis. In the last several years, endoscopic therapies have dramatically changed the need for emergency surgery in patients with upper gastrointestinal bleeding. There is only little information however, regarding the indication criteria and the efficacy of endoscopic therapies in severe upper gastrointestinal bleeding, due to Mallory-Weiss syndrome. This study was designed to assess the usefulness and the indications of endoscopic O-ring band ligation. Methods: Thirty patients with Mallory- Weiss syndrome who were experiencing a related hemorrhage were studied. Among these, 5 patients with active bleeding or a visible vessel revealed during an endoscopic examination were treated with O-ring band ligation. Patients with blood clots or linear tears received only conservative treatment. (Korean J Gastrointest Endosc 18: 152-160, 1998) (continue)

원저 : 식도 위장관 ; 식도정맥류 출혈시 내시경적 경화요법과 고무밴드 결찰요법의 치료 효과 ( Original Articles : Esophagus , Stomach & Intestine ; Comparison of Endoscopic Sclerotherapy & Band Ligation for the Treatment of Esophageal Variceal Bleeding ): Korean J Gastrointest Endosc 1997;17(1):1-7. Published online November 30, 1996

Abstract PDF: Background
/Aims: Endoscopic sclerotherapy is an accepted treatment for the patients with esogeal variceal bleeding, but endoscopic varicea1 band ligation, introduced by Stiegmann et al in 1986, is a new form of endoscopic treatment method, and may be safer. This study is performed to compare the effectiveness and safety of the two techniques. Methods: We compared endoscopic sclerotherapy and endoscopic ligation in 10~8 patients who had recently bled from esophageal varices. We assessed the hemostatic efficacy for bleeding varices, the number of sessions of treatments needed to eradicate varices, the incidence of complications, rebleeding rate and survival rate of the patients by two techniques. Results: Active bleeding was well controlled by sclerotherapy in all of six patients, and ligation in all of five patients by the initial treatment. The mean number of treatment sessions required to achieve eradication did not significantly differ between sclerotherapy and ligation(2.4+0.8 vs 1.8+ 1.0 sessions). Complications were less comman in ligation than sclerotherapy; chest discomfort(5.6% vs 29.6%), fever(3,7% vs 16.7%), esophageal ulcer(0% vs 5.6%), esophageal stricture(0% vs 3.7%). The rate of recurrent bleeding was significantly lower in the patients treated with ligation(p<0.05). The overall rate of survival was significantly higher in the patients treated with ligation(p<0.05), The days of hospitalization was significantly shorter in the patients treated with ligation than sclerotherapy(14.8+-7.0 vs 21.0+-9.7 days). Conclusions: The patients with esophageal variceal bleeding treated with endoscopic ligation have fewer treatment-related complications, lower rates of rebleeding and better survival rates.

Abstract PDF: Endoscopic esophageal variceal ligation(EVL) was first introduced by Stiegmann and colleagues in 1986, and it has since grown to he became an extremely popular modality throughout the world as well as Korea. Endoseopic variceal ligation(EVL), which consists of mechanical ligation and thrombosis of varices using elastic O-rings, has been recently developed as a non-operative alternative to endapic injection sclerotherapy(EIS). EVL is minimally operator-dependent and is also associated with fewer local and systemic complications than sclerotherapy. However, the conventional device has only one O ring, and thus the inner cylinder has to be exchanged after each ligation, So, it is a time-consurning procedure that requires the use of an overtube which has somtimes caused tearing of the esophageal mucosa. To save time and control variceal bleeding, multi-band ligation(MBL) was developed. These ligators have five or six O rings, and serial ligation is now possible without exchanging the cylinder or withdrawing the endoscope.

증례 : 식도 위장관 ; 위편평선종의 고무밴드 결찰술을 이용한 내시경적 점막절제술 2예 ( Case Reports : Esophagus , Stomach & Intestine ; Endoscopic Mucosal Resection with Band Ligation for Two Cases of Gastric Flat Adenoma ): Korean J Gastrointest Endosc 1996;16(3):483-491. Published online November 30, 1995

Abstract PDF: The gastric adenomas could be premalignant lesions and they should be removed as possible, especially in eases with its size aver 2cm. The gastric adenomas can be removed by the various endoscopic methods. Endoscopic polypectomy has been widely used for the treatment of benign and malignant polyps with the advent of technical improvement. Polypectomy with snare and electrocautery is mainly used for pedunculated polyps, but sessile polyps pose some technical difficulties and occasionally cause serious gastrointestinal hemorrhage or perforation. We resected two cases of gastric flat adenoma using Stiegman-Goff ligator used in endoscopic variceal ligation to make flat adenoma as semipedunculated form, and also to decrease the risk of bleeding. After ligation, we successfully removed it with conventional snare polypectomy. We recognized that endoscopic mucosal resection with band ligation can be used for the removal of sessile polyps or flat adenioma with ease, safety and no bleeding.

Abstract PDF: Objectives
Endoscopic variceal ligation is well established metbod of treatment for esophageal varices whereas for gastric varices there has not been any systematic report of its use as a method of treatment. To evaluated its possible clinical application, the band ligation(banding) and the method of band ligation in conjuction with submucosal ethanolamine injection(banding with sclero) were tested on canine stomach, and results were assessed.(Korean J Gastrointest Endosc 16: 145-155, 1996)
