Abstract
PurposeLaparoscopic incisional ventral hernia repair (LIVHR) is often followed by seroma formation, bulging and failure to restore abdominal wall function. These outcomes are risk factors for hernia recurrence, chronic pain and poor quality of life (QoL). We aimed to evaluate whether LIVHR combined with defect closure (hybrid) follows as a diminished seroma formation and thereby has a lower rate of hernia recurrence and chronic pain compared to standard LIVHR.MethodsThis study is a multicentre randomised controlled clinical trial. From November 2012 to May 2015, 193 patients undergoing LIVHR for primary incisional hernia with fascial defect size from 2 to 7 cm were recruited in 11 Finnish hospitals. Patients were randomised to either a laparoscopic (LG) or a hybrid (HG) repair group. The main outcome measure was hernia recurrence, evaluated clinically and radiologically at a 1-year follow-up visit. At the same time, chronic pain scores and QoL were also measured.ResultsAt the 1-year-control visit, we found no difference in hernia recurrence between the study groups. Altogether, 11 recurrent hernias were found in ultrasound examination, producing a recurrence rate of 6.4%. Of these recurrences, 6 (6.7%) were in the LG group and 5 (6.1%) were in the HG group (p > 0.90). The visual analogue scores for pain were low in both groups; the mean visual analogue scale (VAS) was 1.5 in LG and 1.4 in HG (p = 0.50). QoL improved significantly comparing preoperative status to 1 year after operation in both groups since the bodily pain score increased by 7.8 points (p < 0.001) and physical functioning by 4.3 points (p = 0.014).ConclusionLong-term follow-up is needed to demonstrate the potential advantage of a hybrid operation with fascial defect closure. Both techniques had low hernia recurrence rates 1 year after operation. LIVHR reduces chronic pain and physical impairment and improves QoL.Trial Registry: Clinical trial number NCT02542085.
Highlights
In incisional ventral hernia repair, the laparoscopic method (LIVHR) has gained popularity since it reduces postoperative morbidity and hospital stay compared to the open approach [1]
The present study aims to find out whether a hybrid operation with diminished postoperative seroma formation has any impact on hernia recurrence compared to Laparoscopic incisional ventral hernia repair (LIVHR)
90 patients from laparoscopic group (LG) and 82 from hybrid group (HG) returned for the 1-year-control visit
Summary
In incisional ventral hernia repair, the laparoscopic method (LIVHR) has gained popularity since it reduces postoperative morbidity and hospital stay compared to the open approach [1]. LIVHR has not overcome the open method regarding hernia recurrence [11,12,13,14] or chronic pain [15, 16] Because of these issues, LIVHR combined with the defect closure (hybrid or intraperitoneal onlay mesh [IPOM-Plus]) has been introduced in several studies with promising outcome [7, 17, 18]. A few studies have measured the influence of LIVHR on QoL [22,23,24] According to these outcomes, LIVHR appears to reduce chronic pain and physical impairment and improves long-term QoL. LIVHR appears to reduce chronic pain and physical impairment and improves long-term QoL This trial compares hybrid and standard LIVHR with primary outcome measures of seroma formation at 1 month and hernia recurrence at the 1-year follow-up. We evaluated whether closing the defect lowers postoperative chronic pain and improves QoL
