        'Paraumbilical hernia (PH) represents one of the most frequently encountered abdominal wall defects in adult surgical practice, with an estimated lifetime prevalence of 3–10% in the general population. Its management has evolved substantially over the past two decades, shifting from primary suture repair — which historically carried recurrence rates as high as 54.5% — toward mesh-based techniques that offer significantly lower recurrence. Among the available mesh placement positions, two open techniques have gained particular clinical relevance: the preperitoneal (posterior to the peritoneum but anterior to the transversalis fascia) and the retromuscular (Rives-Stoppa; posterior to the posterior rectus sheath, within the retrorectus space) methods. Despite growing adoption of both approaches, direct comparative data on their post-operative outcomes in the specific context of adult paraumbilical hernia remain scarce in the Pakistani surgical literature, necessitating locally contextualised evidence.'

A total of 50 adult patients (25 per group) will be recruited through consecutive non-probability sampling over 12 months. Group A will undergo open preperitoneal mesh repair and Group B will undergo open retromuscular (Rives-Stoppa) mesh repair, with polypropylene mesh used in both groups. The primary outcome measure is 30-day post-operative complication rate, encompassing seroma formation, surgical site infection (SSI), haematoma, wound dehiscence, and early recurrence. Secondary outcomes include operative time, post-operative pain score (VAS at 24 and 72 hours), length of hospital stay, return to normal activity, and patient satisfaction. Data will be analysed using IBM SPSS version 26 with chi-squared, independent samples t-test, and Mann-Whitney U test as appropriate; p < 0.05 will be considered significant.'

      p(
        'Abdominal wall hernias constitute one of the most prevalent surgical conditions worldwide, with paraumbilical hernias accounting for a sizeable proportion of elective general surgical admissions. A paraumbilical hernia is defined as a protrusion of abdominal contents through a defect in the linea alba within 2–3 cm of the umbilical ring, distinct from a true umbilical hernia which traverses the umbilical ring itself. In adults, PH is predominantly an acquired condition, with recognised predisposing factors including obesity, multiparity, chronic raised intra-abdominal pressure, ascites, and prior abdominal surgery. Global estimates suggest a prevalence of 3–10% in the adult population, with a markedly higher burden in populations where obesity rates are rising, as is the case in urban Pakistan (Sabiston Textbook of Surgery, 2022; Mulholland and Greenfield\'s Surgery, 2022). Left untreated, PH carries a risk of incarceration and strangulation, with associated morbidity and mortality, making elective repair the standard of care for fit patients with symptomatic defects.'
      ),
      p(
        'The history of hernia surgery has been defined by the effort to reduce the recurrence rate. Primary suture repair, though technically straightforward, is now well-documented to carry an unacceptably high recurrence rate — meta-analytic evidence reports primary suture closure of umbilical and paraumbilical hernias recurs in up to 54.5% of cases at long-term follow-up, compared with approximately 10% with mesh repair (Dias Rasador et al., Hernia, 2024; PMID 39001938). This evidence has driven the widespread adoption of prosthetic mesh repair. However, within mesh-based approaches, the optimal anatomical plane for mesh placement remains an active area of clinical investigation. The three principal open techniques — onlay (subcutaneous), retromuscular (Rives-Stoppa), and preperitoneal — differ meaningfully in their biomechanical rationale, technical demands, complication profiles, and long-term outcomes (Brucchi et al., J Robot Surg, 2025; PMID 41428244).'
      ),
      p(
        'The retromuscular technique, first codified by Rives and Stoppa, places the mesh posterior to the rectus abdominis muscle within the avascular retrorectus space, enabling large mesh overlap with direct mechanical support from the posterior rectus sheath. This technique exploits the principle that intra-abdominal pressure drives the mesh against the posterior sheath rather than dislocating it, conferring biomechanical stability. By contrast, the preperitoneal approach positions the mesh between the transversalis fascia and the peritoneum, which provides acceptable support for small to medium defects and is technically less demanding in terms of posterior sheath dissection. Despite this, the current literature lacks a dedicated prospective comparative study of these two techniques specifically for adult paraumbilical hernia, particularly in the South Asian operative context. This study is therefore designed to generate evidence that directly addresses this gap, with the expectation of informing evidence-based surgical decision-making in our setting.'

      secHead('Section 1: Current State of Knowledge and Existing Evidence'),
      p(
        'Mesh-based repair has become the accepted standard for elective primary and recurrent paraumbilical hernia repair in adults. The European Hernia Society (EHS) guidelines recommend the use of mesh for all umbilical and paraumbilical hernia defects greater than 1 cm, citing the substantially lower recurrence rates compared with primary suture techniques (Muysoms et al., Hernia, 2015). This recommendation is strongly supported by the meta-analysis of Dias Rasador et al. (Hernia, 2024; PMID 39001938), which pooled data from 12 studies including 2,926 patients and confirmed that mesh repair reduced recurrence by 50% compared with primary suture (RR 0.50; 95% CI 0.31–0.79; p = 0.003). Although mesh use increased seroma rates in the overall analysis (RR 1.88; 95% CI 1.07–3.32), this difference was not statistically significant on subgroup analysis of randomised controlled trials alone, an important methodological observation.'
      ),
      p(
        'Among mesh placement options, the retromuscular (Rives-Stoppa) technique has been most extensively studied in the context of ventral and incisional hernia repair. Sabiston\'s Textbook of Surgery (22nd edition) identifies the Rives-Stoppa retrorectus repair as the benchmark open technique for ventral hernia reconstruction, noting that its biomechanical principle — where elevated intra-abdominal pressure acts to press the mesh against the posterior rectus sheath rather than to displace it — accounts for its consistently low recurrence rates. Reported recurrence rates with the retromuscular technique range from 3.5% to 10% in modern comparative series, representing a significant improvement over earlier non-mesh approaches (Springer meta-analysis, Updates in Surgery, 2024). The technique has been expanded by the Transversus Abdominis Release (TAR) modification, described by Novitsky et al. (2012), which allows mesh placement to extend beyond the linea semilunaris for complex abdominal wall reconstruction (Sabiston, 2022).'
      ),
      p(
        'The preperitoneal approach, alternatively, positions the mesh in the space of Retzius or more broadly between the peritoneum and the transversalis fascia. A systematic review and meta-analysis by Brucchi et al. (J Robot Surg, 2025; PMID 41428244), while conducted in the robotic context, provides the most contemporary comparative data between these two planes: among 3,704 patients (2,326 preperitoneal, 1,378 retromuscular), preperitoneal repair demonstrated significantly shorter operative time (WMD = −39.4 min; 95% CI −58.5 to −20.2; p < 0.001), lower overall complication rates (7.2% vs 15.6%; RR 1.65; 95% CI 1.21–2.26), and reduced wound morbidity (RR 1.81; 95% CI 1.25–2.63). Crucially, recurrence rates were comparable between techniques (1.9% vs 0.5%; RR 0.95; 95% CI 0.29–3.11), suggesting that for small to medium primary defects — the typical profile of paraumbilical hernias — the preperitoneal technique may offer equivalent durability with reduced operative complexity and wound complications. However, the authors explicitly noted that retromuscular repair remains preferable for large or complex defects, and that these findings may not be fully generalisable to the open surgical context.'
      ),
      p(
        'Comparative data from open surgery are more limited. The systematic review by Martins et al. (Langenbecks Arch Surg, 2024; PMID 38307999) compared open and laparoscopic approaches for primary ventral hernia and found no significant difference in recurrence rates, though laparoscopy reduced surgical site infection risk. Studies focusing specifically on paraumbilical hernia and comparing preperitoneal versus retromuscular mesh positioning in an open setting are sparse in the published literature. A prospective study by Hanumanthappa et al. (Cureus, 2025; PMID 39958025) evaluated onlay mesh outcomes for paraumbilical hernia at a peripheral Indian hospital and reported a wound complication rate of 14% and a recurrence rate of 6% over 6 months of follow-up — comparable to the figures generally reported for preperitoneal repair but potentially higher than those achieved with retromuscular fixation. These data collectively confirm that while mesh repair is clearly superior to primary closure, the optimal mesh plane for adult paraumbilical hernia in the open setting requires dedicated prospective investigation.'

The choice of a quasi-experimental rather than a fully randomised design reflects the operational realities of surgical training institutions, where complete allocation concealment and blinding of the operating surgeon is not feasible. However, the study introduces several methodological safeguards including consecutive sampling, standardised operative protocols for both techniques, a standardised polypropylene mesh specification, blinded outcome assessment by a designated research assistant, and prospective follow-up with pre-specified outcome measurement tools.'

In Group A (preperitoneal), the hernia sac will be reduced, the peritoneum closed, and the mesh placed posterior to the transversalis fascia with a minimum 3 cm overlap on all sides. In Group B (retromuscular), the posterior rectus sheath will be incised and opened bilaterally, the retrorectus space developed, and the mesh placed with a minimum 5 cm overlap on all sides, followed by re-approximation of the posterior sheath anterior to the mesh. In both groups, a closed suction drain will be placed and the anterior fascia closed with a running #1 Prolene suture.'

This study directly addresses this question by comparing 30-day complication rates, operative time, pain scores, and patient-reported outcomes between the two techniques, with the expectation that the findings will permit a recommendation for standardised practice at the study institution and contribute to the national surgical literature on hernia repair.'

Conversely, if the preperitoneal technique demonstrates comparable outcomes with shorter operative time, it may be recommended as the technique of choice particularly for smaller defects and less experienced surgeons, with implications for surgical training curricula. The study results will be submitted for publication in a peer-reviewed national or international surgical journal and presented at relevant postgraduate surgical conferences. The data will also contribute to the evidence base considered by the national hernia repair guidelines committee and by UHS in the development of surgical training standards.'
