Clinical Experience of Diagnosis and Surgical Treatment of 6 Cases of Acute Subhepatic Appendicitis

To summarize the experience of diagnosis and surgical treatment of 6 cases of acute subhepatic appendicitis. The clinical data of 6 patients with subacute appendicitis in Zhejiang Provincial People's Hospital from July 2018 to December 2019 were analyzed retrospectively. Results. There were 5 males and 1 female. All 6 cases were diagnosed as appendicitis by abdominal CT before operation. All patients underwent laparoscopic appendectomy without conversion to laparotomy. One case of ectopic appendix was located under the liver with absence of ascending colon, one case of ectopic appendix was located under the liver with ectopic ascending colon of transverse colon, one case of appendix head was located in the liver cyst, and the resection of liver cyst was performed at the same time, and three cases of retrocolonic appendix head were located under the liver. Postoperative pathology confirmed appendicitis. For patients with right upper abdominal pain and tenderness, the possibility of subhepatic appendicitis should be considered before operation. Emergency abdominal CT has more advantages than ultrasound. Laparoscopy can not only make a definite diagnosis but also perform appendectomy at the same time.
