BACKGROUND/AIMS: Food bolus impaction is the most common form of esophageal foreign body impaction observed in adults. Clinical guidelines recommend using the push technique or retrieval methods in such cases. The push technique can cause injuries in certain clinical situations. Notably, conventional retrieval methods are time and effort consuming. Cap-assisted endoscopic extraction of an impacted food bolus is an easy and effective technique; however, more data are needed for its validation. This study compared the capassisted extraction technique with conventional methods. METHODS: This prospective observational multicenter study compared the success and en bloc removal rates, total procedure time, and adverse events in both techniques.. RESULTS: The study included 303 patients who underwent food bolus extraction. The push technique was used in 87 patients (28.7%) and a retrieval procedure in 216 patients (71.3%). Cap-assisted extraction was performed in 106 patients and retrieval using conventional methods in 110 patients. The cap-assisted technique was associated with a higher rate of en bloc removal (80.2% vs. 15%, p<0.01), shorter procedure time (6.9±3.5 min vs. 15.7±4.1 min, p<0.001), and fewer adverse events (0/106 vs. 9/110, p<0.001). CONCLUSIONS: Cap-assisted extraction showed no adverse events, higher efficacy, and a shorter procedure time compared with conventional retrieval procedures.

OBJECTIVEThe present study investigated the protective role of Hyparrhenia hirta (H. hirta) against sodium nitrate (NaNO3)-induced hepatoxicity.
METHODSMale Wistar rats were randomly divided into three groups: a control group and two treated groups during 50 d with NaNO3 administered either alone in drinking water or co-administered with H. hirta.
RESULTSNaNO3 treatment induced a significant increase in serum levels of glucose, total cholesterol and triglyceride while serum total protein level decreased significantly. Transaminases and lactate deshydrogenase activities in serum were elevated indicating hepatic cells' damage after treatment with NaNO3. The hyperbilirubinemia and the increased serum gamma glutamyl transferase activities suggested the presence of cholestasis in NaNO3 exposed rats. In parallel, a significant increase in malondialdehyde level along with a concomitant decrease in total glutathione content and superoxide dismutase, catalase and glutathione peroxidase activities were observed in the liver after NaNO3 treatment. Furthermore, nitrate caused a significant induction of DNA fragmentation. These modifications in NaNO3-treated rats corresponded histologically with hepatocellular necrosis and mononuclear cells infiltration. H. hirta supplementation showed a remarkable amelioration of the abnormalities cited above.
CONCLUSIONThe results concluded that the treatment with H. hirta had a significant role in protecting the animals from nitrate-induced liver dysfunction.
