Port site hernias (PSH) are underreported following laparoscopic ventral hernia repair (LVHR). Most occur at the site of laterally placed 10–12-mm ports used to introduce large pieces of mesh. One alternative is to place the large port through the ventral hernia defect; however, there is potential for increased risk of surgical site infection (SSI). This study evaluates the outcomes when introducing mesh through a 10–12-mm port placed through the hernia defect. This was a retrospective case series of patients who underwent LVHR in three prospective trials from 2014–2017 at one institution. All patients had mesh introduced through a 10–12-mm port placed through the ventral hernia defect. The primary outcome was SSI. Secondary outcomes were hernia occurrences including recurrences and PSH. A total of 315 eligible patients underwent LVHR with a median (range) follow-up of 21 (11–41) months. Many patients were obese (66.9%), recently quit tobacco use (8.8%), or had diabetes (18.9%). Most patients had an incisional hernia (61.2%), and 19.2% were recurrent. Hernias were on average 4.8 ± 3.8 cm in width. Two patients (0.6%) had an SSI. Fourteen patients had a hernia occurrence—13 (4.4%) had a recurrent hernia, and one patient (0.3%) had a PSH. During LVHR, introduction of mesh through a 10–12-mm port placed through the hernia defect is associated with a low risk of SSI and low risk of hernia occurrence. While further studies are needed to confirm these results, mesh can be safely introduced through a port through the defect.

Increasingly, radiologic imaging is obtained as part of the pathway in diagnosing ventral hernias. Often, radiologists receive incomplete or incorrect clinical information from clinicians. Objective: The aim of the study is to determine if clinical exam findings alter radiological interpretation of ventral hernias on CT. This is a single-institution double-blind, randomized trial. All patients with a recent abdominal/pelvic CT scan seen in various surgical clinics were enrolled. A surgeon blinded to the CT scan findings performed a standardized physical examination and assessed for the presence of a ventral hernia. Seven independent radiologists blinded to the study design reviewed the scans. Each radiologist received one of three types of clinical exam data per CT: accurate (correct), inaccurate (purposely incorrect), or none. Allocation was random and stratified by the presence of clinical hernia. The primary outcome was the proportion of radiologic hernias detected, analyzed by chi square. 115 patients were enrolled for a total of 805 CT scan reads. The proportion of hernias detected differed by up to 25% depending on if accurate, no, or inaccurate clinical information was provided. Inaccurate clinical data in patients with no hernia on physical exam led to a significant difference in the radiologic hernia detection rate (54.3% versus 35.7%, p = 0.007). No clinical data in patients with a hernia on physical exam led to a lower radiologic hernia detection rate (75.0% versus 93.8%, p = 0.001). The presence and accuracy of clinical information provided to radiologists impacts the diagnosis of abdominal wall hernias in up to 25% of cases. Standardization of both clinical and radiologic examinations for hernias and their reporting are needed. Clinicaltrials.gov, Number NCT03121131, https://clinicaltrials.gov/ct2/show/NCT03121131.
