CT scan structured report for the study of abdominal wall defects: a fast, easy and practical tool at the service of both surgeons and radiologist

PURPOSE

The advantages offered by structured reporting have already been highlighted in the literature. However, there is still no evidence on the validity of this reporting method for the study of abdominal wall defects. This study aims to show the experience of the Trentino Hernia Team (THT) multidisciplinary group in the development and use of a structured CT scan report for the study of abdominal wall defects.

METHODS

A regional multidisciplinary team (THT group) used a Delphi method to identify and select the most important CT scan parameters needed to describe and stage abdominal wall defects for correct preoperative planning. Based on the selected parameters, a CT scan structured report was worked out and collectively accepted. The first 20 structured reports obtained were individually tested for compilation speed and homogeneity of the data reported by five distinct radiologists. The reports were then evaluated by five different surgeons to test the simplicity of interpretation.

RESULTS

We produced a model of a structured report for the study of the abdominal wall defects and tested it in our hospital network on the first 20 reports. The average completion time was 18 min (range 12-25). There was no heterogeneity among the reported data. The reports were analysed by five distinct surgeons to evaluate completeness and simplicity of interpretation. Each surgeon used a Likert scale from 0 to 5 to evaluate each report, producing average scores of 4.8 and 4.1 for completeness and comprehensibility respectively, with a mean combined total score of 8.9 out of 10.

CONCLUSIONS

Our structured report represents a fundamental tool capable of providing the surgeon with all the measurements of the parameters necessary for correct preoperative planning. At the same time, it is of crucial help for the radiologists representing an easy and fast way to report all the needed parameters using the same standards.

Long-term outcomes and quality of life assessment after posterior component separation with transversus abdominis muscle release (TAR)

BACKGROUND

Although transversus abdominis release (TAR) to treat large incisional hernias has shown favorable postoperative outcomes, devastating complications may occur when it is used in suboptimal conditions. We aimed to evaluate postoperative outcomes and long-term follow-up after TAR for large incisional hernias.

METHODS

A consecutive series of patients undergoing TAR for complex incisional hernias between 2014 and 2019 with a minimum of 6 month follow-up was included. Demographics, operative and postoperative variables were analyzed. Postoperative imaging (CT-scan) was also evaluated to detect occult recurrences. The HerQLes survey for quality of life (QoL) assessment was performed preoperatively and 6 months after the surgery.

RESULTS

A total of 50 TAR repairs were performed. Mean age was 65 (35-83) years, BMI was 28.5 ± 3.4 kg/m², and 8 (16%) patients had diabetes. Mean Tanaka index was 14.2 ± 8.5. Mean defect area was 420 (100-720) cm², average defect width was 19 ± 6.2 cm, and mesh area was 900 (500-1050) cm²; 78% were clean procedures, and in 60% a panniculectomy was associated. Operative time was 252 (162-438) minutes, and hospital stay was 4.5 (2-16) days. Thirty-day morbidity was 24% (12 patients), and 16% (8 patients) had surgical site infections. Overall recurrence rate was 4% (2 patients) after 28.2 ± 20.1 months of follow-up. QoL showed a significant improvement after surgery (p = 0.001).

CONCLUSIONS

The TAR technique is an effective treatment modality for large incisional hernias, showing an acceptable postoperative morbidity, a significant improvement in QoL, and low recurrence rates at long-term follow-up.
