Abstract:

Objective To investigate the value of ultrasound real-time monitoring in early complications after appendectomy. Method The clinical and ultrasonic data of 60 patients with complications after appendectomy in Guilin People's Hospital from January 2023 to December 2024 were retrospectively analyzed. The sonographic characteristics of various complications were recorded and summarized. Result Among the 60 patients with complications after appendectomy, there were 16 cases of ascites, 12 cases of abdominal abscess, 23 cases of incision infection, 6 cases of appendicitis stump, and 3 cases of intestinal obstruction. The diagnosis was verified by the results of operation, puncture or clinical follow-up. The ultrasonic characteristics of ascites were clear-cut anechoic or hypoechoic areas, which were mostly banded or irregular flakes; The ultrasonic characteristics of abdominal abscess were mixed echo masses with irregular boundaries, uneven internal echo, flocculent, reticular or cord like strong echo, some of which were combined with liquid-liquid plane or bubble like strong echo and accompanied by rear "comet tail sign" sound shadow; The ultrasonic features of incision infection were thickened and disordered echo of subcutaneous tissue, blurred hierarchical structure, and patchy or irregular hypoechoic areas were seen locally; The ultrasonic characteristics of appendicitis stump were as follows: a cord like blind end structure appeared in the area adjacent to the root of the cecum, the diameter was thickened, the average transverse diameter was 8.4mm (range 7.2 ～ 10.1mm), low to medium echo, uneven internal echo, and spot or strip hyperechoic in the lumen could be seen; The ultrasonic characteristics of intestinal obstruction were typical intestinal dilatation and fluid gas accumulation. Conclusion Ultrasound has important value in the identification of early complications after appendectomy. It can detect abnormal changes in time through dynamic and noninvasive ways, and has practical significance in judging the nature of lesions, evaluating inflammatory activities and guiding clinical intervention.
