BACKGROUND This case report demonstrates the simultaneous development of a gastrointestinal stromal tumour(GIST)with arteriovenous malformations(AVMs)within the jejunal mesentery.A 74-year-old male presented to the department of surgery at our institution with a one-month history of abdominal ***-enhanced computed tomography revealed an *** exploratory laparotomy,hyperspectral imaging(HSI)and indocyanine green(ICG)fluorescence were used to evaluate the extent of the tumour and determine the resection *** imaging confirmed AVM,while histopathological evaluation showed an epithelioid,partially spindle cell *** SUMMARY This is the first case reporting the use of HSI and ICG to image GIST intermingled with an *** resection margins were planned using intraoperative analysis of additional optical ***-guided surgery enhances the clinician’s knowledge of tissue composition and facilitates tissue *** Since image-guided surgery is safe,this procedure should increase in popularity among the next generation of surgeons as it is associated with better postoperative outcomes.

BACKGROUND There is no established correlation between 24-h esophageal pH-metry(Eso-pH)and the new laryngopharyngeal pH-monitoring system(Restech)as only small case series ***-pH was not designed to detect laryngopharyngeal reflux(LPR)and Restech may detect LPR *** have previously published a dataset using the two techniques in a large patient collective with gastroesophageal reflux ***,patients after esophagectomy were reported to represent an ideal human reflux model as no reflux barrier *** To use a human reflux model to examine our previously published correlation in these *** Patients after Ivor Lewis esophagectomy underwent our routine follow-up program with surveillance endoscopies,computed tomography scans and further exams following *** patients with a complete check-up program and reflux symptoms were offered inclusion into this prospective study and evaluated using Restech and simultaneous ***,the relationship between the two techniques was evaluated RESULTS A total of 43 patients from May 2016-November 2018 were *** patients presented with mainly typical reflux symptoms such as heartburn(74%),regurgitation(84%),chest pain(58%),and dysphagia(47%).Extraesophageal symptoms such as cough,hoarseness,asthma symptoms,and globus sensation were also *** 24-hour pH-metry was abnormal in 88%of patients with a mean DeMeester Score of 229.45[range 26.4-319.5].Restech evaluation was abnormal in 61%of cases in this highly selective patient *** patients with abnormal supine LPR were also abnormal for supine esophageal reflux measured by conventional *** Patients following esophagectomy and reconstruction with gastric interposition can ideally serve as a human reflux ***,laryngopharyngeal reflux phases occur mainly in the upright *** this human volume-reflux model,results of simultaneous esophageal and laryngopharyngeal(Restech)pH
