To explore and analyze the efficacy of multi-slice spiral computed tomography (MSCT) scanning and image post-processing in preoperative classification of groin hernia patients.

The clinical data of 86 cases of adult groin hernia treated by laparoscopic trans-abdominal preperitoneal hernia repair (TAPP) in Xuzhou Traditional Chinese Medicine Hospital from January 2015 to August 2019 were retrospectively analyzed. MSCT and image post-processing were used to evaluate the classification before operation. The imaging features and classification results of patients with different types were counted, and the classification seen in laparoscopy was regarded as the standard. Kappa test was used to analyze the consistency between MSCT and image post-processing examination results and intraoperative findings.

The results of MSCT and image post-processing examination before typing were 77 cases of indirect groin hernia, type Ⅰ in 29 cases, type Ⅱ in 41 cases, type Ⅲ in 7 cases, the results of laparoscopic typing were: type Ⅰ in 30 cases, type Ⅱ in 40 cases, type Ⅲ in 8 cases; The results of MSCT and image post-processing examination before typing were 5 cases of direct groin hernia, type Ⅳ in 2 cases, type Ⅴ in 3 cases, the results of laparoscopic typing were: type Ⅳ in 1 case, type Ⅴ in 4 cases; The results of MSCT and image post-processing examination before typing were 3 cases of groin saddle hernia, type Ⅵ in 3 cases, the results of laparoscopic typing were: type VI in 2 cases; The results of MSCT and image post-processing examination before typing were 1 case of femoral hernia (type Ⅶ), the results of laparoscopic typing were: type Ⅶ in 1 case. The coincidence rates of MSCT and image post-processing preoperative typing and laparoscopic typing were 93.48%, 100%, 79.43%, 100% for indirect groin hernia, direct groin hernia, groin saddle hernia and femoral hernia, respectively. According to Kappa test, MSCT had good consistency with preoperative and laparoscopic classification of indirect groin hernia, direct groin hernia, groin saddle hernia and femoral hernia after image processing (Kappa=0.9106, P<0.05).

MSCT and image post-processing are highly effective in evaluating preoperative classification of groin hernia patients by laparoscopy, and are highly consistent with the results of intraoperative classification.
