Abstract
Esophageal stenosis after ESD has been recorded high for large-scale esophageal lesion. Risk factors for increasing the occurrence of stenosis includes long type lesions, lesions infiltrating into the muscularis mucosa and muscular layer injury. In this case, postoperative stricture of the patient was highly likely occurred. Smectite is a mucosal protective agent that can resist external stimuli, promote wound healing, and reduce inflammatory factors. Therefore, it can effectively prevent the formation of scars on wounds. This study was carried out in humans for the first time and was successful. In conclusion, endoscopic spraying of smectite may be effective and safe in preventing esophageal stenosis after ESD with large non-circumferential lesions.

Topical Application of Siberian Pine Essential Oil Formulations Enhance Diabetic Wound Healing. Pharmaceutics 2023; 15:2437. [PMID: 37896197 PMCID: PMC10610429 DOI: 10.3390/pharmaceutics15102437] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2023] [Revised: 09/18/2023] [Accepted: 09/21/2023] [Indexed: 10/29/2023] Open
Abstract
This study aimed to develop novel topical formulations based on a natural component (0.5% of Siberian pine essential oil) and to assess its wound-healing capacity through macroscopic, histopathological, and biochemical examination. The phytochemical profile of Pinus sibirica essential oil (PSEO) and rheological analysis and safety potential of formulations were determined. The wound-healing effect was evaluated on an excision wound model in diabetic Wistar albino rats randomly divided into the following groups topically treated with (1) untreated, (2) 1% silver sulfadiazine, (3) ointment base, (4) gel base, (5) PSEO ointment, and (6) PSEO gel. Formulations containing PSEO were stable and safe for skin application. Three weeks of treatment with both PSEO formulations (ointment and gel) led to a significant reduction in wound size (98.14% and 96.28%, respectively) and a remarkably higher level of total hydroxyproline content (9.69 µg/mg and 7.26 µg/mg dry tissue, respectively) relative to the control group (65.97%; 1.81 µg/mg dry tissue). These findings were in correlation with histopathological results. Topically applied PSEO formulations were associated with a significant reduction in most of the measured pro-oxidants and enhanced activity of the antioxidant defense system enzymes (p < 0.05). Our findings showed that gel and ointment with PSEO demonstrated significant wound-repairing capabilities in the excision wound model.
