LONG-TERM RESULTS AFTER VIDEO ENDOSCOPIC MYOTOMY BY HELLER WITH FUNDOPLICATION BY DOR IN PATIENTS WITH 2-4 STAGES OF ACHALASIA

Relevance. Treatment of achalasia of the cardia (AС) is currently palliative, aimed at reducing the manifestation of clinical symptoms of the disease. Together with instrumental methods of examination of esophageal function, the Eckardt scale and the GIGLI questionnaire are convenient and simple tools for evaluating results in the long-term postoperative period.The aim of the study was to evaluate the long-term results of surgical treatment of patients with 2-4 stages of AС, after laparoscopic Нeller myotomy with anterior hemiesophagofundoplication by Dor to the results of special methods of esophageal examination and patient questionnaires using the Eckardt scale and the GIGLI questionnaire.Materials and methods. The work included the results of examinations of 103 patients who underwent video laparoscopic Нeller myotomy, with anterior hemiesophagofundoplication by Dor. The period of examination in the postoperative period was from 3 to 7 years. The results of X-ray examination of the esophagus and stomach, manometry of the esophageal and esophageal-gastric junction before and after surgery were studied , and patients were also surveyed according to the Eckardt scale and the GIGLI questionnaire.Results. The analysis of the results of instrumental methods of studying the function of the esophagus in the pre – and postoperative periods showed that the given manometry of the esophagus and esophageal-gastric junction, X-ray of the esophagus and stomach significantly improved in the postoperative period in patients with all stages of the disease. The results of patients of 4th stage AC compared with the results of 2nd and 3rd stages patients were worse(p<0,05).The leading symptom of AK-dysphagia in the long-term postoperative period decreased in all the studied patients, the results were better in patients with stage 2, worse in patients with stage 4 of AK (p<0,05).The leading symptom of AK-dysphagia in the long-term postoperative period decreased in all the studied patients, the 2nd stage patients results were better, 4th stage patients results were worse (p<0,05).Conclusions. After video-endoscopic Нeller myotomy with fundoplication by Dor, the indicators of esophageal manometry and esophageal and stomach radiography significantly improve, the results of the Eckardt scale and GIGLI questionnaire survey of patients show a significant decrease in the severity of clinical manifestations of AC in the balls. This method of surgical treatment can be recommended already at the 2nd stage of AC and as an organpreserving operation for 4th stage.

Effects of remifentanil on pharyngeal swallowing and esophageal motility - no impact of different bolus volumes, and partial antagonism by methylnaltrexone

Background Remifentanil impairs swallowing, and disturbed accommodation to bolus volume may be one of the underlying causes. It is not fully understood whether remifentanil-induced swallowing dysfunction is mediated by peripheral or central mechanisms. Aims To investigate if remifentanil-induced swallowing dysfunction is dependent on the bolus volume and whether the effect of remifentanil could be counteracted by methylnaltrexone, a peripherally acting opioid antagonist. Methods Nineteen healthy volunteers were included in this double-blinded, randomized, placebo-controlled, crossover study. Study participants received target-controlled remifentanil infusions and placebo infusions in a randomized order. Methylnaltrexone was administered by intravenous injection of doses of 0.3 mg/kg. Recordings of pressure and impedance data were acquired using a combined manometry and impedance solid state catheter. Data was analyzed from three series of bolus swallows, baseline, during remifentanil exposure, and 15 min after methylnaltrexone. Results Remifentanil induced significant effects on multiple pharyngeal and esophageal function parameters. No significant differences in remifentanil-induced swallowing dysfunction related to different bolus volumes were found. Pharyngeal effects of remifentanil were not significantly counteracted by methylnaltrexone, whereas on the distal esophageal level, effects on distension pressures were counteracted. Conclusions Changes in pharyngeal and esophageal pressure flow variables were consistent with previous results on remifentanil-induced swallowing dysfunction, and uniform across all bolus volumes. The effects of remifentanil on the pharyngeal level and on the proximal esophagus appear to be predominantly centrally mediated, whereas the effects of remifentanil on the distal esophagus may be mediated by both central and peripheral mechanisms.
