Primary ventral or groin hernia seems rare in pregnancy, and the incidence of emergency repair is extremely low. Watchful waiting strategy is recommended during pregnancy in women suspected for a primary ventral or groin hernia.

The overall recurrence rate after surgically treated ASBO was 12.1%, and the risk of recurrence was persistent several years after index operation. Factors associated with an increased risk were female gender, multiple/matted adhesions, and fascial dehiscence.

Background Mesh reinforcement is recommended for repair of primary ventral hernias; however, this recommendation does not consider a potential subsequent pregnancy. The aim of this prospective cohort study was to compare mesh and suture repair of a primary ventral hernia in women with a subsequent pregnancy. Methods All women of childbearing age who underwent repair of a primary ventral hernia between 2007 and 2014 were identified in the Danish Ventral Hernia Database. Data were merged with the Danish Medical Birth Registry. Women with a subsequent pregnancy and a propensity-score matched control group of women without a subsequent pregnancy were included. A structured questionnaire was sent out, and the primary outcome was hernia recurrence, while the secondary outcome was chronic postoperative pain. Results In total, 632 women were included, of whom 441 (69.8%) responded to the questionnaire (195 and 246 with and without subsequent pregnancy, respectively). The 8-year cumulative incidence of recurrence was 24.8%. In women with a subsequent pregnancy, mesh repair was associated with a decreased risk of recurrence (hazard ratio 0.44, 95% CI 0.20-0.95, p = 0.038, number needed to treat = 5.1) and an increased risk of chronic pain (OR 5.07,, p = 0.029, number needed to harm = 4.7) compared with suture repair, in multivariable analyses. Conclusions Mesh repair was associated with a decreased risk of recurrence, but an increased risk of chronic pain, compared with suture repair in women with a subsequent pregnancy.

Objective: To determine the optimal timing of elective repair, the primary objective of this study was to assess if parity at the time of repair and subsequent pregnancy were associated with reoperation for recurrence. The secondary objective was to examine if parity was associated with hernia formation requiring surgical repair. Summary Background Data: Women of childbearing age constitute 18% of patients operated on for a primary ventral hernia, but consensus is lacking on the management in women who might subsequently become pregnant. Methods: In this nationwide retrospective cohort-study, all women born in Denmark from 1962 to 1971 were eligible for inclusion and followed from age 15 to 45 years. The follow-up rate was 100%. Data on pregnancies and surgical procedures were obtained from the Danish Medical Birth Registry and National Patient Registry. Extended Cox regression and Poisson regression were used for statistical analysis. Results: In total, 470,646 women were included, of whom 2113 underwent repair of a primary ventral hernia. The 10-year cumulative incidence of reoperation for recurrence was 14.1% (95% CI 12.3%–16.0%). Parity at the time of repair was not associated with reoperation for recurrence, while a subsequent pregnancy was associated with a 1.6-fold increased risk (hazard ratio 1.58, 95% CI 1.08–2.31). Parous women had a 7-fold increased risk of undergoing hernia repair compared with nulliparous, in an age-adjusted model (incidence rate ratio 7.04, 95% CI 5.87–8.43). Conclusion: To reduce the risk of hernia recurrence, the optimal timing of elective repair is after the last pregnancy.

Colonic diverticulosis was associated with direct inguinal and umbilical/epigastric hernia repair suggesting that connective tissue alterations, herniosis, could be a common etiologic factor of colonic diverticulosis and these abdominal wall hernias.
