Background: Pregnant women that are complaining from paraumbilical hernia postpone its repair until they get birth. We hypothesized that it will be better to perform hernia repair of such type of hernia simultaneously during performing cesarean section (CS) which will help to decrease future morbidity re-operation, avoid complications and further skin incision. In this study we aimed to compare the value of performing para-umbilical hernia repair simultaneously during performing CS through the same skin incision with performing para-umbilical hernia repair simultaneously during performing CS through another infra- or supra-umbilical skin incision and performing para-umbilical hernia repair electively later on after healing of a CS skin incision in relation to clinical recovery and patient satisfaction. Patients and Methods: This is a prospective cohort study, where we included 45 pregnant female patients who will give birth by CS, and we have divided them into 3 groups: the first group of patients (A) included 15 patients that undergoing paraumbilical hernia repair by pre-peritoneal mesh insertion through CS incision, the second group of patients (B) in-cluded 15 patients that undergoing paraumbilical hernia repair by infra- or supra-umbilical incision during CS incision and the third group of patients (C) included 15 patients that undergoing paraumbilical hernia repair by infra- or supra-umbilical incision later on after healing of the CS wound. We have evaluated advantages of that novel approach e.g. operation time, severity of pain, peri-partum and post-operative complications, financial cost, duration of hospital stay, clinical recovery, mesh rejection, and patient satisfaction. Results: In group A there is shorter duration of hospital stay, no new skin incision (p < 0.001), low incidence of early complications like umbilical ischemia, wound infection, wound dehiscence, seroma, skin flaps ischemia (p = 0.027), low incidence of late complications like painful ugly scar and mesh rejection (p = 0.05). Group A showed the highest incidence of clinical recovery and patients’ satisfaction (p > 0.002). Conclusions: Performing para-umbilical hernia repair by insertion of a pre-peritoneal mesh simultaneously during performing CS through the same skin incision is the best method of management of para-umbilical hernia in pregnant woman.
Para-umbilical hernias are most common in females than males. Pregnancy may lead to occurrence of umbilical hernia, or allow a preexisting one to be more apparent, due to increasing intra-abdominal pressure progressively. Para-umbilical hernia may be diagnosed during 1st, 2nd, or 3rd pregnancies and its presenting symptoms most probably present in the 2nd trimester in most patients [
In this study we aimed to compare the value of performing para-umbilical hernia repair simultaneously during performing CS through the same skin incision with performing para-umbilical hernia repair simultaneously during performing CS through another infra- or supra-umbilical skin incision and performing para-umbilical hernia repair electively later on after healing of a CS skin incision in relation to clinical recovery and patient satisfaction.
1) This is a prospective cohort study in that were performed in departments of; General Surgery, Gynecology & Obstetrics, Internal Medicine, Zagazig University Hospitals, after local ethics committee Approval.
2) Sample size: where we included 45 pregnant female patients we have divided them into 3 groups the first group of patients (A) included 15 patients that undergoing para-umbilical hernia repair by pre-peritoneal mesh insertion through CS incision, the second group of patients (B) included 15 patients that undergoing paraumbilical hernia repair by infra- or supra-umbilical incision during CS incision and the third group of patients (C) included 15 patients that undergoing paraumbilical hernia repair by infra- or supra-umbilical incision later on after healing of the CS wound.
3) Patient’s data:
・ All pregnant full term female patients with age from 25 - 35 years old.
・ All participants were planned CS patients, and had no serious obstetric pathology.
・ Reducible umbilical swelling was present in all cases, and the diagnosis of umbilical hernia was also confirmed by ultrasonography preoperatively.
・ The surgical procedure was explained in detail to the patients, and then a written informed consent form was obtained from all patients.
・ All patients are not diabetic, not hypertensive, no PROM, no neonatal problems.
・ We have excluded all patients with any comorbidity e.g. diabetes or hypertension.
・ We have excluded all patients with premature rupture of membranes (PROM) or fetal problems.
・ Any serious complication during CS is a contraindication to mesh repair of umbilical hernia.
All patients were subjected to the following:
1) Full history taking.
2) Clinical examination with assurance of complete reducibility by palpating the while margin of the hernia defect after reduction of the hernia contents.
3) Preoperative investigations:
- C.B.C.
- Live & renal function tests.
- Plain X-ray chest.
- Ultrasonography.
Antibiotic prophylaxis with 1 g cephalosporin was given to all included patients in our study intravenously after extraction of the placental.
The type of anesthesia: General anesthesia with endotracheal intubation. After disinfection of the surgical area with povidone iodine, the operation begins with about 10 cm classic Pfannenstiel incision. Exposure of the uterus was provided with routine steps, and a standard CS was performed by the obstetrics team.
After the uterine wound has been closed carefully, the operative wound was washed with saline 0.9%. Then, the pre-peritoneal space was entered between rectus muscle and peritoneum with blunt dissection by the general surgery team.
Group: A
1) Position: the patient lies in supine position after end of procedures of CS operation in the form of closure of uterus and doing peritoneal toilet with adequate haemostasis then the patient position should be changed to Trendelenburg position to make viscera away.
2) The operative technique:
From inside abdominal cavity the content of hernia is reduced pathological contents were excised.
Peritoneal incision around defect in posterior sheath (neck of hernia) then upper and lower peritoneal flaps are dissected.
The hernial sac was pulled from inside and excised.
If the umbilicus was distorted it will be fixed with (vicryl suture 2/0) to sheath.
Closure of defect by using continuous sutures vicryl 1.
Fixation of proline mesh (6 × 11) to posterior aspect of sheath by continuous and interrupted sutures proline 2/0.
Closure of peritoneal flaps over mesh without drain.
Closure of CS wound.
Group: B & Group: C
The patient is lying supine. Infra- or supra-umbilical incision is done according to the site of hernia. Skin flaps were created. Dissection of sac and opening it from the neck then reduction of the content. Closure of defect. Fixation of the mesh by interrupted proline sutures. Closure in layers with subcutaneous suction drain.
Good peritoneal toilet and closure of the CS wound was done as usual.
・ All patients were followed up in the early postoperative period for the following:
- Length of hospital stays (1 - 2 days).
- Early wound infection or Ischemia, dehiscence or seroma.
- Post-operative pain.
- Postoperative pain was evaluated by the average consumption of analgesic ampules given on patient demand during the first week.
- All patients received a routine intramuscular dose of 75-mg dose of diclofenac sodium (Voltaren IM; Novartis, Basel, Switzerland) twice on the day of the operation.
- Total analgesic usage was registered during the first postoperative week.
- The patients were followed-up postoperatively daily until discharge from the hospital, then twice weekly as an outpatient for the first 2 weeks, then 1 month later, and finally every 6 month.
Data of our patients were computerized and analyzed statistically using SPSS program (Statistical Package for Social Science). Chi square test (χ2) and Fisher exact was used to calculate difference between qualitative variables. p-value ≤ 0.05 is considered significant, p < 0.001 is considered highly significant while, p > 0.05 is considered Non-significant difference.
Main features and clinical data of our patients are included in
Group A patients are better than the other both groups regarding no new skin incision, no drain was used that was statistically significant (p < 0.001).
We found that Group A patients are better than the other both groups regarding decreasing low incidence of early complications like umbilical ischemia, wound infection, wound dehiscence, seroma, skin flaps ischemia (p = 0.027).
Low incidence of late complications like painful ugly scar and mesh rejection (p = 0.05).
Group A showed the highest incidence of clinical recovery and patients’ satisfaction (p > 0.002).
There were no statistically significant differences between all groups regarding presence of skin flaps ischemia.
Repairing hernia during C-section is an approach of surgical management of such lesion. But, performing both surgeries simultaneously neither were nor recommended until the 2000s [

Our results were similar to results of Kulacoglu [
The practical benefits of our novel approach were as follows; a 2-in-1 operation, a single incision, single anesthesia, and single hospital stay, more advantages for patient and hospital, lower cost, and better convenience, in addition to avoid the separation of the mother from her baby in case of re-operation.
The obstacle that may face the surgeon during the combine procedure is difficult intraoperative mesh fixation that can be solved by good assistance to allow good traction that was similar to Ghnnam et al. [
Obstetric surgeons and General surgeons prefer to postpone hernia repair to avoid increase length of the operative time, increased risk of post-partum complications and may prolong hospitalization.
Our results in addition to results of Ghnnam et al. [
We found that no patients in the first group of patients group A have; post-operative infections, seroma or prolonged hospitalization, that was slightly different from results of Ghnnam et al. [
healing due to infection in six patients, seroma occurred in three patients such discrepancy may be due to different patient numbers or different follow-up period.
Similar to Ghnnam et al. [
It remains a matter of controversy whether to repair paraumbilical hernia in a pregnant woman during pregnancy, at cesarean delivery or at the postpartum after involution of the uterus. Many surgeons prefer not to repair the hernia during pregnancy as anesthesia and surgery during pregnancy might precipitate uterine irritability, contraction and induce premature labor, up to 1 week postoperatively [
Oma et al. [
Surgit et al. [
In our study we have compared performing paraumbilical hernia repair as a combined procedure with CS through the same incision with performing paraumbilical hernia repair as a combined procedure with CS through 2 incisions one of the CS and the other for hernia repair and with paraumbilical hernia repair as elective procedure later on after healing of the scar of CS and we have found that performing paraumbilical hernia repair as a combined procedure with CS through the same incision is the best procedure. As, cesarean delivery combined with paraumbilical hernia repair is well accepted us regarding simplicity, safety and efficacy.
Performing para-umbilical hernia repair by insertion of a pre-peritoneal mesh simultaneously during performing CS through the same skin incision is the best method of management of para-umbilical hernia in pregnant woman.
Confirmation of these results needs a larger study so as to establish if combined CS and hernia repair as a novel recommended procedure.
