Background/Aims:Complications are important determining factors for safety of endoscopic submucosal dissection (ESD) for gastric heterotopic pancreas (HP). This study investigated whether endoscopic color Doppler ultrasonography (ECDUS) could be used to predict the feasibility, efficacy, and safety of ESD.Patients and Methods:The study included 52 patients with heterotopic pancreas of the gastric antrum who underwent ECDUS before ESD. ECDUS was used to evaluate the submucosal vascular structure and the location of HP in gastric wall. The patients who had a vessel at least 500 μm in diameter or at least 10 vascular structures per field of view were classified into the rich group (Group R), and others were classified into the non-rich group (Group N). Procedure time, decrease in hemoglobin, frequency of clip use, complications, recurrence rate, and others were retrospectively evaluated.Results:There were 18 patients in Group R and 34 patients in Group N. Mean procedure time was significantly longer in group R (55.4 min) than in group N (35.5 min) (P = 0.014). The incidence of muscle injury and clip use were significantly higher in group R (77.8/83.3%) than in group N (20.6/23.5%) (P < 0.05). Mean decrease in hemoglobin was 2.5 g/dL in group R and 2.4 g/dL in group N, with no significant difference. There were no recurrences in any cases during the follow-up period.Conclusion:Preoperative identification of submucosal vascular structure by ECDUS can predict procedure time and the incidence of muscle injury and clip use, which is particularly suitable for predicting ESD safety in heterotopic pancreas of stomach.
Background and Objective: Colorectal serrated polyp is considered as histologically heterogeneous lesions with malignant potential. The aim of the study was to evaluate the endoscopic, clinic and pathologic characteristics of colorectal serrated polyps. Methods: The endoscopic, clinic and pathologic characteristics of 52 cases with colorectal serrated polyps between January 2014 and May 2018 in our hospital were analyzed. retrospectively. Results: The prevalence of serrated polyps was 0.39% (52/13,346). The proportions of hyperplastic polyp (HP), sessile serrated adenoma/polyp (SSA/P), and traditional serrated adenoma (TSA) of all serrated polyps were 61.5%, 17.3%, and 21.2%, respectively, which showed a lower proportion of TSA and SSA/P and a higher proportion of HP. Conclusions: The overall detection rate of colorectal serrated polyps was relatively low, and it is necessary to discriminate between SSAPs and HPs during endoscopic examination because of the malignant potential.
