Long-term results of retromuscular hernia repair: a single center experience

Ventral hernia is a chronic disease: a systematic review of long-term outcomes beyond 5 years

PURPOSE

To systematically evaluate the long-term outcomes of ventral hernia repair (VHR) and reassess its classification as a definitive surgical intervention. This review synthesizes evidence on postoperative complications including recurrence, chronic pain, and patient-reported outcomes to characterize the long-term burden of VHR and its impact on patient management. This study underscores the necessity of prolonged postoperative surveillance to accurately assess surgical efficacy and inform evidence-based follow-up trategies.

METHODS

A systematic review was conducted in accordance with PRISMA guidelines, searching PubMed, Embase, and Web of Science for studies with a mean or median follow-up of ≥5 years. Eligible studies reported outcomes including recurrence, reoperation, mesh infection, chronic pain, and quality of life. A random-effects meta-analysis was performed using STATA MP 18 to pool event rates for each outcome.

RESULTS

Among 2,721 patients followed for ≥5 years, 13% (95% CI: 9-17%) experienced recurrence. Long-term complications included seroma in 11% (95% CI: 6-17%, n = 1,778) and reoperation in 8% (95% CI: 5-11%, n = 1,833) of patients. Patient-reported outcomes, including chronic pain, were collected, with 15% (95% CI: 8-23%, n = 1,220) reporting its occurrence.

CONCLUSION

This systematic review evaluates the complexity of ventral hernia repair and proposes conceptual realignment in managing ventral hernias, viewing them through the lens of chronic disease to align treatment goals with long-term patient outcomes. The data suggests that ventral hernias exhibit characteristics of a chronic condition, requiring sustained medical oversight and potential reinterventions for chronic pain, recurrence, and other quality-of-life complications.

Favourable outcomes after Retro-Rectus (Rives-Stoppa) Mesh Repair as Treatment for Non-Complex Ventral Abdominal Wall Hernia, a Systematic Review and Meta-Analysis

OBJECTIVE

To assess prevalence of hernia recurrence, surgical site infection (SSI), seroma, serious complications, and mortality after retro-rectus repair.

SUMMARY BACKGROUND DATA

Ventral abdominal wall hernia is a common problem, tied to increasing frailty and obesity of patients undergoing surgery. For non-complex ventral hernia, retro-rectus (Rives-Stoppa) repair is considered the gold standard treatment. Level-1 evidence confirming this presumed superiority is lacking.

METHODS

Five databases were searched for studies reporting on retro-rectus repair. Single-armed and comparative randomized and non-randomized studies were included. Outcomes were pooled with mixed-effects, inverse variance or random-effects models.

RESULTS

Ninety-three studies representing 12440 patients undergoing retro-rectus repair were included. Pooled hernia recurrence was estimated at 3.2% (95%CI: 2.2-4.2%, n = 11049) after minimally 12 months and 4.1%, (95%CI: 2.9-5.5%, n = 3830) after minimally 24 months. Incidences of SSI and seroma were estimated at respectively 5.2% (95%CI: 4.2-6.4%, n = 4891) and 5.5% (95%CI: 4.4-6.8%, n = 3650). Retro-rectus repair was associated with lower recurrence rates compared to onlay repair (OR: 0.27, 95%CI: 0.15-0.51, p < 0.001) and equal recurrence rates compared to intraperitoneal onlay (IPOM) repair (OR: 0.92, 95%CI: 0.75-1.12, p = 0.400). Retro-rectus repair was associated with more SSI than IPOM repair (OR: 1.8, 95%CI: 1.03-3.14, p = 0.038). Minimally invasive retro-rectus repair displayed low rates of recurrence (1.3%, 95%CI: 0.7-2.3%, n = 849) and SSI (1.5%, 95%CI: 0.8-2.8%, n = 982), albeit based on non-randomized studies.

CONCLUSIONS

Retro-rectus (Rives-Stoppa) repair results in excellent outcomes, superior or similar to other techniques for all outcomes except surgical site infection. The latter rarely occurred, yet less frequently after IPOM repair, which is usually performed by laparoscopy.

A systematic review of outcome reporting in incisional hernia surgery

Background

The incidence of incisional hernia is up to 20 per cent after abdominal surgery. The management of patients with incisional hernia can be complex with an array of techniques and meshes available. Ensuring consistency in reporting outcomes across studies on incisional hernia is important and will enable appropriate interpretation, comparison and data synthesis across a range of clinical and operative treatment strategies.

Methods

Literature searches were performed in MEDLINE and EMBASE (from 1 January 2010 to 31 December 2019) and the Cochrane Central Register of Controlled Trials. All studies documenting clinical and patient-reported outcomes for incisional hernia were included.

Results

In total, 1340 studies were screened, of which 92 were included, reporting outcomes on 12 292 patients undergoing incisional hernia repair. Eight broad-based outcome domains were identified, including patient and clinical demographics, hernia-related symptoms, hernia morphology, recurrent incisional hernia, operative variables, postoperative variables, follow-up and patient-reported outcomes. Clinical outcomes such as hernia recurrence rates were reported in 80 studies (87 per cent). A total of nine different definitions for detecting hernia recurrence were identified. Patient-reported outcomes were reported in 31 studies (34 per cent), with 18 different assessment measures used.

Conclusions

This review demonstrates the significant heterogeneity in outcome reporting in incisional hernia studies, with significant variation in outcome assessment and definitions. This is coupled with significant under-reporting of patient-reported outcomes.
