    Abstract: Background and study aims Recent evidence suggests that lugol chromoendoscopy (LCE) and narrow-band imaging (NBI) have comparable sensitivity for detection of superficial esophageal squamous cell carcinoma (SCC). However, LCE is time-consuming and associated with side effects. The aim of this study was to compare the effectiveness of NBI and LCE in defining resection margins of esophageal SCC. Patients and methods This was a retrospective observational cohort study of patients with esophageal SCC and dysplasia who underwent en-bloc resection between 1999 and 2017 at the Cliniques universitaires Saint-Luc, Brussels. Two groups were defined: 1) inspection with NBI only; and 2) inspection with LCE (with or without NBI). The primary endpoint was complete lateral resection rate. Multivariate regression was used to adjust for potential confounders. Results A total of 102 patients with 132 lesions were included. Lesions were inspected with LCE in 52 % (n = 68) and with NBI only in 48 % (n = 64). Lesions 0-IIa were more frequent in the NBI group (37 %) and 0-IIb (60 %) in LCE. Lesion location, size, and histology and resection technique (endoscopic submucosal dissection in 122/132 cases, 92 %) were similar between the groups. The rate of complete lateral resection for invasive carcinoma was 90 % in LCE group and 94 % in NBI group (P = 0.498) and 65 % and 67 % (P = 0.813), respectively, for dysplasia complete lateral resection. These results remained non-significant after adjusting for potential confounders. Conclusions Mucosal inspection and delineation of tumors with lugol chromoendoscopy before endoscopic resection of esophageal squamous cell lesions was not associated with increased complete lateral resection rate when compared to NBI.

    Abstract: Background and study aims The choice of endoscopic submucosal dissection (ESD) or endoscopic mucosal resection (EMR) in non-ampullary superficial duodenal tumors (NASDTs) is challenging and the benefits of ESD remain unclear. The aim was to comparatively analyze the feasibility, outcomes and safety of these techniques in these lesions. Patients and methods This is an observational and retrospective study. All consecutive patients presenting with NASDTs who underwent EMR or ESD between 2005 and 2017 were included. The following main outcomes were comparatively evaluated: en-bloc and complete (R0) resection rates, and local recurrence. Secondary outcomes were perforation and delayed bleeding. Results One hundred sixty-six tumors in 150 patients (age: 66 years, range: 31 – 83, 42.7 % males) were resected by ESD (n = 37) or EMR (n = 129) and included. The median procedure time (81 vs. 50 min, P = 0.007) and tumor size (25 vs. 20 mm, P = 0.01) were higher in the ESD group. The global malignancy rate was 50.3 %. There were no differences in en-bloc resection (29.7 % vs. 44.2 %, P = 0.115), complete resection (19.4 % vs. 35.5 %, P = 0.069), and local recurrence (14.7 % vs. 16.7 %, P = 0.788) rates. Tumor size was associated with recurrence (28 vs. 20 mm, P = 0.008), with a median follow-up of 6.5 months. Focal recurrence (n = 22, 13.3 %) was treated endoscopically in 86.4 %. En-bloc resection in the ESD group was comparable in large ( ≥ 20 mm) and small lesions (27.6 % vs. 37.5 %, P = 0.587), while this outcome decreased significantly in large lesions resected by EMR (17.4 % vs. 75 %, P  〈  0.001). Nine perforations were confirmed in 6 lesions (16.2 %) resected by ESD and 3 (2.3 %) by EMR (P = 0.001). Endoscopic therapy was successful in all but 1 patient (88.9 %) presenting with a delayed perforation. Conclusions ESD may be an alternative to EMR and surgery in selected NASDTs, such as large duodenal tumors where EMR achieves low en-bloc resection rates and the local recurrence may be higher. However, this technique may have a higher risk of perforations.

    ESD versus EMR in non-ampullary superficial duodenal tumors: a systematic review and meta-analysis

    Abstract: Background and study aims Endoscopic submucosal dissection (ESD) has been developed as an option for treatment of esophageal, gastric and colorectal lesions. However, there is no consensus on the role of ESD in duodenal tumors. Methods This systematic review and meta-analysis compared ESD and endoscopic mucosal resection (EMR) in sporadic non-ampullary superficial duodenal tumors (NASDTs), including local experience. We conducted a search in PubMed, Scopus and the Cochrane library up to August 2017 to identify studies that compared both techniques reporting at least one main outcome (en-bloc/complete resection, local recurrence). Pooled outcomes were calculated under fixed and random-effect models. Subgroup analyses were conducted. Results A total of 753 patients presenting with 784 NASDTs (242 ESD, 542 EMR) in 14 studies were included. Tumor size (MD: 5.88, [CI95 %: 2.15, 9.62] , P = 0.002, I2 = 79 %) and procedure time (MD: 65.65, [CI95 %: 40.39, 90.92], P  〈  0.00001, I2 = 88 %) were greater in the ESD group. En-bloc resection rate was significantly higher in Asian studies (OR: 2.16 [CI95 %: 1.15, 4.08], P = 0.02, I2: 46 %). ESD provided a higher complete resection rate (OR: 1.63 [I95 %: 1.06, 2.50] , P = 0.03, I2: 59 %), but there was no risk difference in the risk of local recurrence (RD: – 0.03 [CI95 %: – 0.07, 0.01], P = 0.15, I2: 0 %) or delayed bleeding. ESD was associated with an increased number of intraoperative perforations [RD: 0.12 (CI95 %: 0.04, 0.20), P = 0.002, I2: 56 %] and emergency surgery for delayed perforations. The inclusion of eligible studies was limited to retrospective series with inequalities in comparative groups. Conclusions Duodenal ESD for NASDTs may achieve higher en-bloc and complete resections at the expense of a greater perforation rate compared to EMR. The impact on local recurrence remains uncertain.
