“…Herniography is a highly reliable diagnostic modality; however, invasiveness and potential complications, such as intestinal puncture, limit its use [2,26]. Miyaki et al and Kamei et al reported CT detection rates of 100% and 98.3%, respectively [27,28]. Although CT diagnosis of hernia has an excellent objectivity, the use of CT is limited by radiation exposure and medical economy.…”

“…Recently, US imaging was reported to be useful for musculoskeletal disorders in patients with sarcopenia and painful shoulder syndromes [12,13]. The usefulness of US for diagnosing inguinal hernia has been reported for a few decades; however, there are few reports on the significance of US in the diagnosis of a groin mass, with no large case series comparing physicians' diagnosis to US diagnoses, and inguinal hernias types between US diagnosis and surgical diagnosis [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29]. In 2010, our institute introduced US for the differential diagnosis of a groin mass; since then, we have been validating US diagnosis with surgical diagnosis on a case-by-case basis.…”

Aim: There is a concern that the differential diagnosis of a groin mass depends on a physicians’ subjective judgment and experience. We aimed to clarify the significance of US in the diagnosis of a groin mass.Material and methods: This retrospective study included 1,898 patients who underwent US examination of a groin mass. Physicians’ diagnoses were compared with US-based diagnoses. Furthermore, the incidence of asymptomatic contralateral hernia was analyzed. The frequency of unnecessary surgery in patients with and without preoperative US was compared. In 1,451 patients who underwent surgery with preoperative US, the preoperative US classification was compared with surgical diagnosis.Results: Of 1,805 patients diagnosed with an inguinal hernia by physicians, 190 (10.5%) exhibited no US findings of inguinal hernia. US revealed asymptomatic contralateral hernia in 13.3% of the 1,543 patients in whom a physician detected unilateral inguinal hernia. The frequency of unnecessary surgery was significantly associated with preoperative US (1/1451; 0% vs. 2/351, 0.6%; p=0.0382). The overall US diagnostic accuracy for the inguinal hernia type was 92.7%.Conclusions: US imaging of a groin mass can help avoid unnecessary surgery, detect latent inguinal hernia, and guide surgical planning.

“…[8] Kamei et al reported a high detection rate and ability to differentiate the inguinal hernia types using prone CT based on an analysis of 1029 hernias. [20] Hernia CT scans can also be performed without contrast, alleviating concerns about contrast agent allergies. Therefore, we routinely perform hernia CT scans for all patients with inguinal hernias.…”

“…These results were relatively inferior to those from Kamei et al (detection rate and accuracy: 98.3% and 95.8%, respectively). [20] There are 2 possible reasons for this discrepancy. The first is the number of subjects in the current study might have been too small to adequately evaluate the hernia CT detection rate and classification accuracy for each type.…”

Physical examination is the standard diagnostic approach for adult inguinal hernias. We aimed to evaluate the clinical utility of routine preoperative computed tomography scans in the prone position for predicting intractable cases of inguinal hernias before performing transabdominal preperitoneal repairs. We retrospectively analyzed 56 lesions in 48 patients with inguinal hernias who underwent prone computed tomography scans prior to transabdominal preperitoneal repairs. To assess the ability of prone computed tomography to enable the accurate preoperative diagnosis of inguinal hernias, we compared preoperative hernia types as classified through hernia computed tomography and intraoperative diagnosis. We also analyzed the relationship between operation time and hernia type in unilateral cases (n = 40). The overall hernia computed tomography detection and classification accuracy rates were 81.0% and 83.9%, respectively, using the Japan Hernia Society classification system (2009 version) and 84.3% and 91.2%, respectively, using the European Hernia Society classification system. There were no differences in the hernia type frequencies between the shorter (n = 20) and longer (n = 20) operation time groups. Two patients had sliding inguinal hernias with prolapsing bladders, both of which were detectable using preoperative prone computed tomography. Although transabdominal preperitoneal repairs were completed in both cases, the operation times were exceptionally long (185 and 291 minute). Preoperative prone computed tomography is useful for predicting intractable cases of inguinal hernias. Prone computed tomography can play a significant role in not only typing and differentiating hernias from other diseases, but also in helping surgeons appropriately treat unexpected intractable cases with laparoscopic surgery.
