[PMID: 37022519 DOI: 10.1007/s10103-023-03755-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2023] [Accepted: 03/27/2023] [Indexed: 04/07/2023]
Abstract
Lasers emit highly directional light with consistent wavelengths, and recent studies have demonstrated their successful applications in gastrointestinal endoscopic therapy. Although argon plasma coagulators (APC) became the preferred treatment option due to improved safety profile and lower costs, advancements in laser and optic fiber manufacturing have reignited interest in laser treatment. Different laser wavelengths have distinct features and applications based on their tissue absorption coefficient. Lasers with shorter wavelengths are effectively absorbed by hemoglobin, resulting in a good coagulation effect. Near-infrared lasers have ability to ablate solid tumors, while far-infrared lasers can make precise mucosal incisions without causing peripheral thermal damage. Lasers have proven to be highly applicable to endoscopy devices such as endoscopes, endoscopic ultrasound (EUS), double-balloon enteroscopes (DBE), and endoscopic retrograde cholangiopancreatography (ERCP), making them a potent tool to enhance the effectiveness of endoscopic treatments with minimal adverse events. This review aims to help readers understand the applications and effectiveness of lasers in gastrointestinal endoscopy, with the potential to promote the development and application of laser technology in the medical field.

Abstract
Objectives and study aims
Recent pilot studies have assessed the feasibility of a novel 1.9-/1.5-μm dual emission endoscopic laser treatment (
1.9-/1.5-μm
DEELT) for endoscopic hemostasis, ablation and resection. In this study, we investigated the safety and efficacy of
1.9-/1.5-μm
DEELT in patients with chronic anemia due to gastrointestinal vascular lesions in a real-life multicenter cohort setting.
Patients and methods
Consecutive patients with moderate/severe iron-deficiency anemia undergoing
1.9-/1.5-μm
DEELT for upper and lower gastrointestinal bleeding due to vascular lesions were enrolled in three academic referral centers. Safety and successful ablation of vascular lesions were the primary outcomes. Long-term hemoglobin level, blood transfusion requirements, endoscopic severity scores of complex vascular disorders and technical lasing parameters were also assessed. Long-term hemoglobin variations have been further assessed, with repeated measure analysis of variance and univariate analyses.
Results
Fifty patients (median age 74; range 47 to 91 years) with gastric antral vascular ectasia (GAVE) (22), angioectasia (22) and radiation proctopathy (6) underwent 58
1.9-/1.5-μm
DEELT between 2016 and 2020. All procedures were technically feasible leading to successful ablation of the targeted lesion/s, with no incident or adverse event potentially related to the
1.9-/1.5-μm
DEELT technique. Within a 6-month follow-up, hemoglobin values significantly rose (+ 1.77 at 1 month and + 1.70 g/dL at 6 months,
P
< 0.01), the blood supply requirement decreased (at least one transfusion in 32 versus 13 patients,
P
< 0.01), and GAVE lesions showed a clear endoscopic improvement (from 5 points to 1 points,
P
< 0.01).
Conclusions
The 1.9-/1.5-μm laser system is a safe and effective endoscopic tool for haemostatic ablation of bleeding vascular lesions within the gastrointestinal tract in tertiary referral centers.

Abstract
BACKGROUND Despite a high prevalence of angiodysplasia, no specific guidelines are available for the modalities of endoscopic exploration of gastrointestinal (GI) bleeding in von Willebrand disease (VWD). Whether VWD patients could benefit from video capsule endoscopy (VCE) looking for angiodysplasia eligible to endoscopic treatment or at high risk of bleeding is unknown. OBJECTIVES To assess the diagnostic efficacy for angiodysplasia and the prognostic value of VCE on top of conventional endoscopy in VWD patients with GI bleeding. PATIENTS/METHODS A survey was sent to the 30 centers of the French-network on inherited bleeding disorders to identify VWD patients referred for endoscopic exploration of GI bleeding from January 2015 to December 2017. Data obtained included patient characteristics, VWD phenotype/genotype, GI bleeding pattern, results of endoscopic investigations, and medical management applied including endoscopic therapy. We assessed by Kaplan-Meier analysis the recurrence-free survival after the first GI bleeding event according to endoscopic categorization and, in patients with angiodysplasia, to the presence of small-bowel localizations on VCE exploration. RESULTS GI bleeding source localization was significantly improved when including VCE exploration (P < .01), even in patients without history of angiodysplasia (P < .05). Patients with angiodysplasia had more GI bleeding recurrences (P < .01). A lower recurrence-free survival was observed in patients with angiodysplasia (log-rank test, P = .02), and especially when lesions were located in the small bowel (log-rank test, P < .01), even after endoscopic treatment with argon plasma coagulation (log-rank test, P < .01). CONCLUSION VCE should be more systematically used in VWD patients with unexplained or recurrent GI bleeding looking for angiodysplasia eligible to endoscopic treatment or at high risk of relapse.

Abstract
Rectal erosions after ventral rectopexy (VR) is an uncommon but challenging adverse event and can be associated with partial migration of the mesh into the intestinal cavity. Re-do surgery is difficult and often provides colostomy and/or anterior rectal resections. However, no alternative solutions are described in the available literature. An 82-year-old woman presented to our hospital for rectal erosion and intraluminal migration of the mesh placed at a 1-year laparoscopic VR. We performed an innovative totally endoscopic approach, using thulium laser and two endoscopes, that led to a successful removal of the mesh. The described mini-invasive technique can be an effective alternative to surgery in tertiary referral centres.

Abstract
PURPOSE OF REVIEW Gastric vascular abnormalities are a well known cause of gastrointestinal bleeding. Due to their recurrent bleeding tendency and potential to cause life-threatening blood loss, gastric vascular abnormalities can result in significant morbidity and cost. RECENT FINDINGS There have been novel advances in medical and endoscopic management of gastric vascular lesions. New data suggest that endoscopic band ligation and ablation may be comparable, or even superior, to argon plasma coagulation (APC) for management of gastric antral vascular ectasia (GAVE). A creative, highly sensitive and specific computer-assisted tool has been developed to facilitate reading video capsule endoscopies for the detection of angiodysplasias, paving the way for artificial intelligence incorporation in vascular lesions diagnostics. Over-the-scope clipping is a relatively new technology that shows promising results in controlling bleeding from Dieulafoy's lesions. SUMMARY In this article, we will broadly review the management of the most prevalent gastric vascular lesions, focusing on the most recent areas of research.
