Abdominal hernias in pregnancy

An obstetrician-gynecologist's review of hernias: risk factors, diagnosis, prevention, and repair

Management of obstetrical and gynecologic patients with hernias poses challenges to providers. Risks for hernia development include well-described factors that impair surgical wound healing and increase abdominal pressure. Among the diverse populations cared for by obstetricians and gynecologists, pregnant patients and those with gynecologic malignancies are at the highest risk for hernia formation. This article provides an overview of the existing literature, with a focus on patients cared for by obstetrician-gynecologists and commonly encountered preoperative and intraoperative scenarios. We highlight scenarios when a hernia repair is not commonly performed, including those of patients undergoing nonelective surgeries with known or suspected gynecologic cancers. Finally, we offer multidisciplinary recommendations on the timing of elective hernia repair with obstetrical and gynecologic procedures, with attention to the primary surgical procedure, the type of preexisting hernia, and patient characteristics.

Severe Irreversible Diastasis Recti Abdominis and Abdominal Hernia in Postpartum Women: Rare Case Report

Diastasis recti abdominis is a condition defined as the separation between the rectus abdominis and the linea alba, which leads to weakness in the abdominal muscles. Diastasis may be slight or severe, sometimes resulting in herniation of the abdominal viscera. Following childbirth, most women develop some extent of muscle separation in the postpartum period. However, if the diastasis recti abdominis in the postpartum period remain severe, it should be corrected to prevent concurrent abdominal hernia, strangulation or incarceration. We herein present two Korean cases of postpartum women with severe diastasis recti abdominis with abdominal hernia; it is the first report of its kind from Korea. Two women were referred to our clinic with severe abdominal bulge. Computerized tomography scan showed widening of the linea alba with abdominal hernia. The standard abdominoplasty with multiple wide longitudinal plications of the abdominal wall was performed in each patient under general anesthesia. There was no recurrence of diastasis recti abdominis or abdominal hernia during follow-up periods. The application of abdominoplasty in postpartum women with severe diastasis recti abdominis with abdominal hernia is thus considered to be an efficient management option. We hope these cases can provide a reference for the treatment of similar situations.

Combined procedure of cesarean delivery and preperitoneal mesh repair for inguinal hernia: An initial experience

BACKGROUND

Combined surgery for cesarean delivery and preperitoneal mesh repair for inguinal hernia has not been previously reported.

OBJECTIVES

Our aim was to describe the method and to present the results of this simultaneous surgery through a single incision.

METHODS

From 2012 to 2014, 15 patients underwent cesarean delivery combined with preperitoneal mesh repair for inguinal hernia. All patient characteristics and perioperative findings were recorded.

RESULTS

Among 15 patients, 13 had unilateral inguinal hernias and two had bilateral hernias. The mean times spent for unilateral and bilateral hernias were 35.8 minutes (range, 30-45 minutes) and 67.5 minutes (range, 65-70 minutes), respectively. Direct and indirect hernias were present in one and 15 patients, respectively. One patient had mixed hernia. No significant complication was observed perioperatively. Hospital stay ranged from 1 day to 3 days (mean, 1.87 days), and all patients were discharged without any problem. No recurrence was found during the follow-up periods.

CONCLUSION

Single anesthesia, single incisional scar, and single hospitalization are the major advantages of this simultaneous approach of cesarean delivery and preperitoneal mesh repair for inguinal hernia. Our analysis suggests that this combined procedure can be performed safely in selected cases.

Recurrent umbilical or epigastric hernia during and after pregnancy: A nationwide cohort study

BACKGROUND

Umbilical and epigastric (umb/epi) hernia repairs are performed commonly in fertile female patients. Recent studies suggest mesh repair to be superior to suture repair; however, evidence is lacking concerning the optimal treatment of umb/epi hernias in female patients who might wish future pregnancies. The aim of this study was to compare the cumulative recurrence rate after mesh versus suture repair of umb/epi hernia in female patients subsequently becoming pregnant.

METHODS

This retrospective nationwide cohort study included female patients who underwent primary umb/epi hernia repair and subsequently became pregnant between 2007 and 2013. The follow-up began at first day of pregnancy and ended May 2015. Data were obtained from the Danish Ventral Hernia Database, Medical Birth Registry, and National Patient Registry. Patients with recurrence before pregnancy were excluded.

RESULTS

In total, 224 patients were analyzed. The median follow-up was 3.8 years (range 0.1-8.1). The cumulative recurrence rate was 16.3% after mesh repair and 10.9% after suture repair, P = .299. Univariate Cox regression analysis (mesh repair hazard ratio 1.63, 95% confidence interval 0.71-3.72, P = .249) and multivariate analysis adjusted for body mass index and hernia defect size (mesh repair hazard ratio 2.77, confidence interval 0.98-7.85, P = .055) likewise showed no significant difference in the risk of recurrence when we compared mesh and suture repair.

CONCLUSION

Contrary to findings in the general operative patient, mesh repair was not associated with a lesser risk of recurrence compared with suture repair for treatment of umb/epi hernia in female patients with subsequent pregnancy.

Ventral hernia with uterine rupture after vaginal delivery

OBJECTIVE

Ventral hernia is uncommon during pregnancy and is extremely rare in postpartum women. It leads to a life-threatening emergency.

CASE REPORT

A 33-year-old woman, gravida 2 para 1, was admitted to our institute with severe abdominal pain and overdistended abdomen immediately after a full-term vaginal delivery. She had a normal prenatal course and denied having any medical and surgical history. The primipara woman with no history of abdominal surgery was diagnosed with a ventral hernia with uterine rupture after vaginal delivery. We performed an emergency laparotomy and primary repair of the uterine rupture and abdominal wall defect. An abdominal binder was provided for the postoperative period. The patient's postoperative period was uncomplicated. She was discharged from the hospital after 12 days.

CONCLUSION

If a patient has hernia-related symptoms or complications, the diagnosis and management of the hernia should be performed as soon as possible, regardless of the onset, to decrease maternal and fetal mortality.

Epigastric hernia in pregnancy: a management plan based on a systematic review of literature and a case history

Symptomatic epigastric hernia is rare in pregnant women. A case history, management of which prompted a systematic review of the literature and proposed plan for treatment of such cases, is hereby presented. There is paucity of information on management of this condition in the standard literature as searches in Pubmed, Science Direct, Hinari, Medline, African Journal Online, Bioone as well as Cochrane library revealed. There are two schools of thought for the management of hernias in pregnancy-watchful waiting and herniorrhaphy in pregnancy. There is no consensus or definite guideline on the management of epigastric hernias in pregnancy. Based on the literature review, a management algorithm is proposed, which combines the two schools of thought.
