In addition, the patient experienced hemorrhage from the Roux-en-Y-anastomotic site in the contact with the ileus tube during treatment for septicemia on POD14, which was resolved with endoscopic treatment.Moreover, a cholecystectomy was performed on POD52 for gangrenous cholecystitis.The patient's progress was satisfactory.The pathology results revealed an undifferentiated carcinoma with the following characteristics: pT4a (SE), ly1, v0, pPM1, pDM0, type 2, 80 × 75 mm, UE...Continue Reading
