World J Clin Cases 2022; 10:12793-12798. [PMID: 36579119 PMCID: PMC9791497 DOI: 10.12998/wjcc.v10.i34.12793] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/04/2022] [Revised: 11/02/2022] [Accepted: 11/08/2022] [Indexed: 12/02/2022] Open
Abstract
BACKGROUND Endoscopic submucosal dissection (ESD) is the treatment of choice for early gastric cancer and premalignant gastric dysplasia. In some cases, ESD induced ulcer heals as a polypoid nodular scar (PNS). These scars may make the physicians raise several clinical implications such as post-ESD neoplastic recurrence.
CASE SUMMARY We described a case of gastric ESD induced PNS which is regressed after Helicobacter pylori (H. pylori) eradication. A 58-year-old male patient was referred to the outpatient clinic for evaluation and treatment of gastric low-grade dysplasia (LGD). ESD was performed. A PNS was developed at the ESD site. An endoscopic biopsy was done and there was no histological evidence of remnant tumor or recurrence but a hyperplastic mucosal change. The PNS showed increase in size in follow-up endoscopy, and the biopsy specimen demonstrated H. pylori infestation. H. pylori eradication was done and the PNS was regressed.
CONCLUSION H. pylori eradication is considerable for the regression of PNS if H. pylori infestation is confirmed.

Abstract
Background/Aims: Endoscopic submucosal dissection (ESD) for gastric neoplasms is a widely performed procedure. Local recurrence is rare, but various post-ESD scars are encountered during follow-up endoscopy. Therefore, we investigated atypical scar patterns and evaluated the associated factors.Materials and Methods: Clinicopathologic and endoscopic reviews of gastric neoplasms treated with ESD from January 2009 to December 2015 were conducted. Atypical scar patterns were classified as irregular erythema, nodularity, or mucosal defect.Results: A total of 264 patients with 274 gastric neoplasms, including 201 adenomas and 73 early gastric cancers, were enrolled. The key endoscopic findings at the resection scar were defined on the basis of gross morphology as follows: irregular erythema, mucosal defect (erosion or ulcer), and nodularity. An irregular erythema scar pattern was associated with male sex, a nodularity scar pattern with smoking, and a mucosal defect scar pattern with infra-angle location (angle and antrum) and cancer. An irregular erythema with nodularity scar pattern was also associated with male sex. An irregular erythema with nodularity and mucosal defect scar pattern was associated with liver disease and chronic kidney disease.Conclusions: The atypical scar patterns after gastric ESD are associated with various clinicopathologic factors.

Abstract
BACKGROUND AND STUDY AIM Standard gastrectomy with lymphadenectomy is recommended following endoscopic submucosal dissection (ESD) due to the risk of lymph-node metastasis for resected cancers. However, when lymphatic flows remain unchanged after ESD, a minimally invasive function-preserving surgery based on the sentinel node (SN) concept may be applicable. In this study, using porcine survival models, we aimed to investigate whether gastric lymphatic flows were modified following ESD. METHODS Twelve pigs, each with one simulating lesion 3 cm in size, were used. Indocyanine green (ICG) fluid was endoscopically injected into the submucosa in four quadrants surrounding the lesion. Following laparoscopic observation of lymphatic flows, the lesions were resected by ESD. After 4 weeks, ICG fluid was injected in four quadrants surrounding the scar and lymphatic flows were observed in the same manner as the initial procedure. The distribution of lymphatic flows, including stained SNs, was compared. RESULTS In ten lesions (83.3%), the distribution of flows remained unchanged. However, in one lesion, the flow along the right gastric epiploic artery (R-GEA) disappeared on the lesser curvature of the middle stomach. In addition, in one lesion, the flow along R-GEA emerged on the lesser curvature of the lower stomach. CONCLUSIONS Our study revealed that, despite ESD, lymphatic flows remained unchanged in most parts of the stomach. The SN concept may be applied after ESD, except for lesions on the lesser curvature. However, in the case of the lesser curvature, special care must be given to the SN concept.

Abstract
Background and study aims A post-endoscopic submucosal dissection (ESD) scar is expected to look homogeneous, however, some patients develop benign polypoid nodule scar (PNS). Incidence of PNS is unknown, yet these scars have direct clinical implications because they may render evaluation of post-ESD neoplastic recurrence difficult. Therefore, we reviewed the clinical experience of 5 ESD referral centers and evaluated their PNS incidence and clinical management. Patients and methods This was a retrospective multicenter case series enrolling patients that underwent R0, curative gastric ESD from 2003 to 2015 in 5 academic centers. PNS was defined as ESD site nodularity with hyperplastic or regenerative tissue histology. Results A total of 2275 patients underwent gastric ESD with endoscopy control and 28 patients (18 men/10 women) developed PNS for overall incidence of 1.2 %. Incidence of PNS ranged from 0.15 % to 11.4 % between centers. All patients that developed PNS had primary neoplastic lesions located in the distal stomach. Considering only lesions situated in the antrum (n = 912), incidence of PNS was 3.1 %. After mean follow-up of 43 months (range 6 - 192), no malignant recurrence in the PNS has been identified. In five patients (17.8 %) PNS disappeared after a mean of 18 months. Conclusion PNS occurs exclusively after ESD in the distal stomach in approximately 3.1 % of patients. Although PNS appearance can be concerning, no malignant recurrence was observed after curative R0 resection. Therefore, PNS should be viewed as a benign alteration that does not require any type of intervention, other than endoscopic surveillance.

Endosc Int Open 2018; 6:E98-E103.

Abstract
BACKGROUND AND STUDY AIMS The full-thickness resection device (FTRD) represents a novel endoscopic treatment method for lesions unresectable with conventional endoscopic techniques. The overall aim of this study was to evaluate technical success and in toto resection rates, recurrence rates, as well as immediate or late complications in patients who underwent polyp removal with the FTRD. PATIENTS AND METHODS Data from a prospectively collected database of 12 patients who underwent 13 over-the-scope clip-based full-thickness resections between June 2015 and June 2017 were analyzed. Follow-up endoscopy was performed in 11 out of 12 patients. RESULTS 13 full-thickness resections were performed in 7 males and 5 females (mean age 64.3 ± 6.3 years). Mean size of the lesions removed with FTRD was 17 ± 4 mm. Location was rectum (n = 6), cecum (n = 2), ascending colon (n = 2), left flexure (n = 1) and right flexure (n = 2). Mean procedure time was 68 ± 35 minutes and mean hospital stay was 2.5 ± 1.2 days. 2 patients developed post-polypectomy syndrome, which resolved after conservative treatment. No perforations and no immediate surgical revision were needed. Histology of the 13 lesions removed with FTRD showed 5 adenomas with low grade intraepithelial neoplasia (IEN), 4 high grade IEN, 1 fibrosis, 1 fibrosis without dysplasia and 2 adenocarcinomas. Technical success was achieved in all procedures (13/13, 100 %). R0 resection was achieved in 10/12 patients (83.3 %). 2 patients underwent surgery because of recurrence or not evaluable margins. In 1 patient no residual malignancy was proven in histological examination, in the other patient residual low grade IEN adenoma. CONCLUSION FTRD is a minimally invasive approach with good success rate of complete resection and minimal side effects.
