The CT scans of the remaining 149 patients after the exclusion criteria were included in the study. All CT imaging was performed using multidetector CT (64 or 128 slice) in portal venous phases. The images were evaluated by two radiologists based on consensus. Maximum MPV diameter were measured outer wall to outer wall with calipers on axial images at the level of 1\u2009cm distal to the portosplenic confluence.<\/jats:p><jats:p>\n          Results\u2003One hundred forty-nine patients included in the study had preoperative CT examination. Eighty-three patients had follow-up CT examination at third month, 89 patients at sixth month, and 99 patients at first year. The MPV diameters differed significantly between preoperative CT and postoperative third month, sixth month, and first year CT (p\u2009=\u20090.001, p\u2009=\u20090.001, and p\u2009=\u20090.001, respectively). There was no difference in MPV diameter between postoperative third month CT and postoperative 6th month and 1st year CT (p\u2009=\u20090.514 and p\u2009=\u20090.078, respectively).<\/jats:p><jats:p>\n          Conclusion\u2003There is an increase in MPV diameter in the first 3 months postoperatively in patients undergoing gastric surgery for malignancy. This enlargement continues unchanged in the first 1 year follow-up. The radiologists' awareness of this situation may prevent the wrong diagnosis of portal hypertension, unnecessary concern, and further investigation.<\/jats:p>","DOI":"10.1055\/s-0043-1775739","type":"journal-article","created":{"date-parts":[[2023,10,10]],"date-time":"2023-10-10T23:09:53Z","timestamp":1696979393000},"page":"214-219","source":"Crossref","is-referenced-by-count":0,"title":["Main
