Background: Foreign body (FB) ingestion in the gastrointestinal tract is a common and urgent problem observed in children and adults. However, there may be difficulty locating FBs and complications associated with their removal. This study aimed to identify risk factors and complications correlated to the presence and removal of FBs.Methods: This 5-year retrospective study enrolled 1,311 patients between June 2014 and April 2019.Demographic and endoscopic data were collected, containing age, gender, types and location of FBs, duration of FB ingestion, accessory devices, endoscopic methods, and complications. Logistic regression analysis was applied to evaluate the predictive risk factors.Results: Among 1,131 patients, FBs were found in 90.16% of cases. A major predictor for the presence of FB was a presentation of less than 24 hours (h). The types of FBs were jujube pits (36.72%) and fish bones (22.00%), and over 80% of the FBs were discovered in the esophagus. Complications were found in 239 cases (20.22%), of which hemorrhage (162/239, 67.78%) was the most frequent. Age ≥60, duration ≥24 h, and FBs ingested in the esophagus were considered as risk factors for developing complications. Conclusions:In conclusion, the longer duration, age ≥60, and impaction in the esophagus were risk factors for developing complications following the ingestion of FBs. These factors should be considered when developing assessment and treatment plans in the management of FB ingestion.
Background and aims On the basis of lesser rates of major adverse events and a short-term efficacy as Heller’s myotomy, there is a growing enthusiasm in favor of peroral endoscopic myotomy (POEM), whereas study comparing POEM and pneumatic dilatation (PD) is quite rare. The aim of this study was to evaluate the efficacy of POEM and PD in Chinese achalasia patients in a retrospectively designed study. Methods Patients with achalasia, who underwent either PD (n = 26) or POEM (n = 40) were retrospectively recruited from September 2010 through March 2016 at a single tertiary center. During the 1-year follow-up, clinical outcome and functional data of lower esophageal sphincter (LES) were recruited. Clinical symptoms were assessed by use of the Eckardt score. The primary outcome was therapeutic success (Eckardt score ≤ 3). Functional data of LES (4-second integrated relaxation pressure [4s-IRP], LES relax rate, and LESP) at baseline and 1 month after treatment were also evaluated. Data was analyzed by SPSS 13.0 version using a significance level of p < 0.05. Results The success rates were 24/26 (92.31 %), 25/26 (96.15 %), and 24/26 (92.31 %), respectively, with POEM, as compared with 35/40 (87.50 %), 29/40 (72.50 %), and 23/40 (57.50 %), respectively, with PD, 1 month, 3 months, and 1 year after treatment. Statistically significant difference was observed between the 2 therapies (at 3 months, Fisher’s exact test, p = 0.01; at 1 year, Fisher’s exact test, p < 0.0001). Compared with PD, the Eckardt score was lower with POEM 1 month, 3 months, and 1 year after treatment. More patients in POEM group reported gastroesophageal reflux symptoms (after 3 months 7/26 (26.92 %) vs. 2/40 (5.00 %), Fisher’s exact test, p = 0.01; after 1 year 6/26 (19.23 %) vs. 1/35 (2.86 %), Fisher’s exact test, p = 0.02). The postoperative 4s-IRP and LESP were both lower with POEM than with PD, respectively. Type I achalasia had a better response with POEM than with PD. Conclusion In this retrospective analysis with 1-year follow-up, POEM presents with a higher success rate and more reflux symptoms compared with PD. Change on LES function after treatment may explain the outcome in part. Type I achalasia may respond better to therapies compared with type II.
To investigate the therapeutic effects of phellodendrine in ulcerative colitis (UC) through the AMPK/mTOR pathway. Volunteers were recruited to observe the therapeutic effects of Compound Cortex Phellodendri Liquid (Huangbai liniment). The main components of Compound Cortex Phellodendri Liquid were analysed via network pharmacology. The target of phellodendrine was further analysed. Caco‐2 cells were cultured, and H2O2 was used to stimulate in vitro cell model. Expression levels of LC3, AMPK, p‐AMPK, mTOR and p‐mTOR were detected via Western blotting and through immunofluorescence experiments. The therapeutic effects of phellodendrine were analysed via expression spectrum chip sequencing. The sequencing of intestinal flora further elucidated the therapeutic effects of phellodendrine. Compared with the control group, Compound Cortex Phellodendri Liquid could substantially improve the healing of intestinal mucosa. Network pharmacology analysis revealed that phellodendrine is the main component of Compound Cortex Phellodendri Liquid. Moreover, this alkaloid targets the AMPK signalling pathway. Results of animal experiments showed that phellodendrine could reduce the intestinal damage of UC compared with the model group. Findings of cell experiments indicated that phellodendrine treatment could activate the p‐AMPK /mTOR signalling pathway, as well as autophagy. Expression spectrum chip sequencing showed that treatment with phellodendrine could promote mucosal healing and reduce inflammatory responses. Results of intestinal flora detection demonstrated that treatment with phellodendrine could increase the abundance of flora and the content of beneficial bacteria. Phellodendrine may promote autophagy by regulating the AMPK‐mTOR signalling pathway, thereby reducing intestinal injury due to UC.
