Acute appendicitis in the short term following radical total gastrectomy misdiagnosed as duodenal stump leakage:A case report

摘要

BACKGROUND Common diseases after radical gastrectomy include cholecystitis and pancreatitis,but the sudden onset of acute appendicitis in a short period following radical gastrectomy is very rare,and its clinical symptoms are easily misdiagnosed as duodenal stump leakage.CASE SUMMARY This is a case report of a 77-year-old woman with lower right abdominal pain 14 d after radical resection of gastric cancer.Her pain was not relieved by conservative treatment,and her inflammatory markers were elevated.Computed tomography showed effusion in the perihepatic and hepatorenal spaces,right paracolic sulcus and pelvis,as well as exudative changes in the right iliac fossa.Ultrasoundguided puncture revealed a slightly turbid yellow-green fluid.Laparoscopic exploration showed a swollen appendix with surrounding pus moss and no abnormalities of the digestive anastomosis or stump;thus,laparoscopic appendectomy was performed.The patient recovered well after the operation.Postoperative pathology showed acute purulent appendicitis.The patient continued adjuvant chemotherapy after surgery,completing three cycles of oxaliplatin plus S-1(SOX regimen).CONCLUSION Acute appendicitis in the short term after radical gastrectomy needs to be differentiated from duodenal stump leakage,and early diagnosis and surgery are the most important means of treatment.
