Abstract
BACKGROUND AND AIM Lugol chromoendoscopy is the standard technique to detect an esophageal squamous cell carcinoma (ESCC). However, a high concentration of Lugol's solution can induce mucosal injury and adverse events. We aimed to investigate the optimal concentration of Lugol's solution to reduce mucosal injury and adverse events without degrading image quality. METHODS This was a two-phase double-blind randomized controlled trial. In phase I, 200 eligible patients underwent esophagogastroduodenoscopy and then were randomly (1:1:1:1:1) sprayed with 1.2%, 1.0%, 0.8%, 0.6%, or 0.4% Lugol's solution. Image quality, gastric mucosal injury, adverse events, and operation satisfaction were compared to investigate the minimal effective concentration. In phase II, 42 cases of endoscopic mucosectomy for early ESCC were included. The patients were randomly assigned (1:1) to the minimal effective (0.6%) or conventional (1.2%) concentration of Lugol's solution for further comparison of the effectiveness. RESULTS In phase I, the gastric mucosal injury was significantly reduced in 0.6% group (P < 0.05). Furthermore, there was no statistical significance in image quality between 0.6% and higher concentrations of Lugol's solution (P > 0.05, respectively). It also showed that the operation satisfaction decreased in 1.2% group compared with the lower concentration groups (P < 0.05). In phase II, the complete resection rate was 100% in both groups, while 0.6% Lugol's solution showed higher operation satisfaction (W = 554.500, P = 0.005). CONCLUSIONS The study indicates that 0.6% might be the optimal concentration of Lugol's solution for early detection and delineation of ESCC, considering minimal mucosal injury and satisfied image. The registry of clinical trials: ClinicalTrials.gov (NCT03180944).

Demarcation of early esophageal squamous cell carcinoma during endoscopic submucosal dissection: A comparison study between Lugol's iodine staining and narrow-band imaging. Medicine (Baltimore) 2021; 100:e27760. [PMID: 34941029 PMCID: PMC8701867 DOI: 10.1097/md.0000000000027760] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/17/2021] [Accepted: 10/28/2021] [Indexed: 01/05/2023] Open
Abstract
Lugol's iodine staining (LIS) and narrow-band imaging (NBI) are currently the most common methods applied in demarcating early esophageal squamous cell carcinoma (EESCCs) during endoscopic submucosal dissection. The purpose of the present study was to investigate the effects on clinical outcomes in comparison between LIS and NBI for the demarcation of EESCCs during endoscopic submucosal dissection.This was a single-center, retrospective, cohort study. A total of 172 patients were involved. 109 patients received demarcation of the lesion by LIS and 63 patients by NBI. Data on baseline characteristics, clinical outcomes and follow-up information were collected for analyses.The mean diameter of the lesions was 3.9 ± 1.5 cm. R0 resection rate was 89.5%. The rate of total and in-hospital adverse events was 25.6% and 9.3%. The cumulative recurrence rate was 2.9% and 3-year disease-specific survival rate was 98.3%. Compared to patients of the LIS group, patients of the NBI group showed significantly shorter procedure time (44.8 ± 32.2 v.s.57.0 ± 40.6, P = .044), lower rate of using of scopolamine butylbromide (19.0% vs 35.8%, P = 0.021), reduced number of clips used (1.3 ± 1.2 vs 1.8 ± 1.5, P = .017) and alleviated discomfort evaluated by visual analog system score after operation (4.7 ± 0.8 vs 5.5 ± 1.0, P < .001). There was no significant difference of R0 resection rate, margin status, adverse events, cumulative recurrence rate and 3-year disease-specific survival rate between the two groups.Demarcation of EESCCs by NBI could achieve comparable accuracy and clinical outcomes with more convenience and safety compared with demarcation by LIS.
