Abstract
BACKGROUND This meta-regression aims to investigate risk factors for abdominal hernia and bulge in patients undergoing deep inferior epigastric perforator (DIEP) flaps and the effect of prophylactic mesh placement on postoperative complications. METHODS A systematic search was conducted in July of 2022 in alignment with the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Seventy-four studies published between 2000 and 2022 met the inclusion criteria. Sixty-four studies were included in the analysis for bulge and 71 studies were included in the analysis for hernia. Meta-regressions were run on the proportion of patients experiencing hernia or bulge to assess for patient risk factors and the role of prophylactic mesh placement. Proportions were transformed using the Freeman-Tukey double arcsine method. RESULTS The average rates of hernia and bulge after DIEP flaps were found to be 0.18% and 1.26%, respectively. Increased age (β = 0.0059, p = 0.0117), prior abdominal surgery (β = 0.0008, p = 0.046), and pregnancy history (β = -0.0015, p = 0.0001) were significantly associated with hernia. Active smoking (β = 0.0032, p = 0.0262) and pregnancy history (β = 0.0019, p < 0.0001) were significantly associated with bulge. Neither the perforator vessel laterality nor the number of perforator vessels harvested had any association with hernia or bulge. Prophylactic mesh placement was not associated with hernia or bulge. CONCLUSION Understanding the comorbidities associated with hernia or bulge following DIEP flap breast reconstruction, such as advanced age, prior abdominal surgery, pregnancy history, and active smoking status, allows surgeons to proactively identify and educate high-risk patients. Future studies may further explore whether prophylactic mesh placement offers patients any benefit.

Abstract
BACKGROUND Much of our knowledge about inguinal hernias is based on males. Meanwhile, it is established that women have worse outcomes after inguinal hernia repair, with more chronic pain and higher recurrences. Pediatric literature shows inguinal hernias in females are more likely to be bilateral, incarcerated, and carry a stronger genetic predisposition than males. We aimed to evaluate sex-based differences in inguinal hernia factors in adults, to help supplement the paucity of literature in the adult population. METHODS An institutional database of patients undergoing repair of primary inguinal hernias was queried with focus on preoperative risk factors and operative characteristics. Multivariate analysis was performed looking for independent variables associated with a greater number of hernia defects found intraoperatively. RESULTS Among 494 patients, 202 (40.9%) were female. Number of risk factors among females was significantly higher than males (1.53 vs 1.2, p = 0.003). Females had significantly more constipation, GERD, and asthma and lower BMI than males. Family history of hernias was similar between both sexes. As expected, females had significantly less direct hernias (12.9% vs 32.9%, p < 0.001) and more femoral hernias (38.5% vs 12.2%, p < 0.001) than males. Bilaterality was similar. Females undergoing inguinal hernia repair averaged 1.23 prior deliveries. Regression analysis showed age, sex, BMI, and number of deliveries were not correlated with the number of defects. CONCLUSIONS Females undergoing primary inguinal hernia repair had more preoperative risk factors for inguinal hernia than males. In our population, there was no higher incidence of bilaterality or significant genetic predisposition in females as noted by family history of hernias. Age, sex, BMI and number of deliveries did not correlate with the number of hernia defects found. Our study promotes awareness of inguinal hernias in females and presents new data to quantify sex-based differences and predispositions to inguinal hernias.

Abstract
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.

Abstract
INTRODUCTION Abdominal hernias, including incisional hernias, can occur due to weakness in the abdominal wall. Incisional hernias commonly occur following surgical incisions, and factors such as poor closure technique and patient-related factors can contribute to their development. CASE PRESENTATION In this case, the patient was presented with a painful, irreducible lump over a previous laparotomy scar, along with bowel obstruction symptoms. The diagnosis was supported by ultrasound findings showing obstructed bowel loop in the hernial sac. Emergency open surgical reduction and mesh repair were performed to treat the strangulated hernia and ensure the mother and fetus's safety. The patient had an uneventful postoperative period and was discharged after three days. DISCUSSION Incisional hernias can be diagnosed through clinical evaluation, and imaging studies may be necessary in complex cases. However, imaging techniques such as X-rays and Computed Tomography scans are limited in pregnant women due to the radiation risks. Ultrasonography (USS) is preferred in pregnant women for its safety and non-invasiveness, although it may have reduced sensitivity in obese patients. Complicated hernias should be treated with emergency surgical repair, while elective surgery can be considered for asymptomatic or non-complicated hernias. Laparoscopic surgery offers advantages such as shorter hospital stays and fewer complications. Mesh repair reduces the recurrence risk in subsequent pregnancies (relate the discussion with the case). CONCLUSION Overall, surgical management of hernias in pregnancy requires careful consideration of individual circumstances and the use of appropriate techniques to ensure the safety of both the mother and fetus.

Abstract
INTRODUCTION In recent surgical literature, gender-specific differences in the outcome of hernia surgery has been analyzed. We already know that female patients are at higher risk to develop chronic postoperative pain after inguinal, incisional, and umbilical hernia surgery. In this study, we evaluated the impact of gender on the outcome after epigastric hernia surgery. METHODS A covariable-adjusted matched-paired analysis with data derived from the Herniamed registry was performed. In total of 15,925 patients with 1-year follow-up data were included in the study. Propensity score matching was performed for the 7786 female (48.9%) and 8139 male (51.1%) patients, creating 6350 pairs (81.6%). RESULTS Matched-paired analysis revealed a significant disadvantage for female patients for pain on exertion (12.1% vs. 7.6%; p < 0.001) compared to male patients. The same effect was demonstrated for pain at rest (6.2% in female patients vs. 4.1% in male patients; p < 0.001) and pain requiring treatment (4.6% in female patients vs. 3.1% in male patients; p < 0.001). All other outcome parameters showed no significant differences between female and male patients. CONCLUSIONS Female patients are at a higher risk for chronic pain after elective epigastric hernia repairs compared to the male patient population. These results complete findings of previous studies showing the same effect in inguinal, umbilical, and incisional hernia repair.

Abstract
A hernia is a common surgical problem. Although hernias during pregnancy are uncommon, they can be challenging for both the surgeon and the patient if present. To date, there is no consensus in the medical community regarding the elective repair of hernias in pregnant women. The debate mainly concerns three areas: the timing, the approach, and the surgical technique. This study aims to offer a clear pathway in this field based on the best available data. In this study, we collected reviews written in English and published in PubMed from 2010 to 2020 (the exception being three articles that were published before 2010, which we retained since they contained relevant information). We used regular and Medical Subject Headings (MeSH) keywords. Two of the authors screened the collected studies to select the best articles that would fit our inclusion criteria for the review. The articles considered for this review can be classified into retrospective studies, case reports, and reviews. No randomized controlled trials were found. The lack of an agreement about the treatment of ventral hernias in fertile women makes the decision to treat and the process challenging. The treatment significantly depends on two factors: the symptoms and the pregnancy status at diagnosis. If the hernia is incarcerated or strangulated at presentation, an emergency repair is obligatory. If the hernia is symptomatic, but not complicated, elective surgery should be offered. The timing of repair will depend on whether the patient is already pregnant or non-pregnant. In pregnant patients, if the hernia is small and asymptomatic, it may be better to delay the surgery until after delivery or after the last pregnancy. If the hernia is symptomatic and seems to affect the patient's quality of life, it may be better to postpone the repair until the second trimester or after delivery if complications do not occur. Internal herniation (IH) should be suspected as a cause of the abdominal pain in pregnant women who have undergone laparoscopic Roux-en-Y gastric bypass (LRYGB). In pre-pregnancy patients, if the hernia is large and symptomatic, it may be better to do an elective repair and then wait for one or two years before the next pregnancy. However, if the hernia is small or minimally symptomatic, it may be better to hold the repair until after delivery or after the last pregnancy. Pregnancy may be considered a significant risk factor for hernia recurrence. The laparoscopic mesh repair should be offered whenever possible, whereas the open approach may be preferred in complicated cases. The suture repair may be suitable for both small hernias and in cases of gross contamination.

Abstract
PURPOSE Herniorrhaphy is a source of substantial cost and morbidity. Although women are a substantial proportion of patients seeking repair, gender-specific data, including the influence of childbirth on hernia recurrence, are lacking. Our objective was to estimate the rate and identify risk factors for repeat herniorrhaphy in reproductive-aged women. METHODS Retrospective cohort study of women who underwent herniorrhaphy during June 2000-December 2014 in the United States. Women aged 18-50 who underwent umbilical, incisional/ventral, or inguinal/femoral herniorrhaphy in the Truven Health Analytics MarketScan® Commercial Claims and Encounters database were included. Women without a hernia diagnosis or multiple/concurrent index herniorrhaphy types were excluded. Primary outcome of interest was second herniorrhaphy. RESULTS Of 123,674 women, 13% had a second herniorrhaphy within 10 years; increasing age, comorbidities, childbirth, smoking, obesity, and inpatient procedure were independently associated with increased risk. Cesarean delivery before umbilical herniorrhaphy (HR 1.61, 95% CI 1.34, 1.92) and both vaginal (HR 2.57, 95% CI 1.98, 3.34) and cesarean delivery (HR 2.95, 95% CI 2.25, 3.87) after umbilical herniorrhaphy were associated with increased risk of second herniorrhaphy. Both vaginal (HR 1.66, 95% CI 1.13, 2.43) and cesarean delivery (HR 2.72, 95% CI 2.09, 3.53) after incisional/ventral herniorrhaphy and vaginal delivery after inguinal/femoral herniorrhaphy (HR 1.75, 95% CI 1.22, 2.51) were associated with increased risk of second herniorrhaphy. CONCLUSIONS Among reproductive-aged women, childbirth, increasing age, comorbidities, smoking, and obesity increase risk of subsequent herniorrhaphy. Risk of second herniorrhaphy is higher with cesarean delivery compared to vaginal delivery, and higher for delivery occurring after initial hernia repair compared to before.

Abstract
BACKGROUND & AIMS Although incisional hernia repair in women of childbearing age is not rare, hernia disease in this group of patients is sparsely documented. The aim of this study was to examine long-term clinical results after incisional hernia repair in women of childbearing age. MATERIAL AND METHODS This nationwide cohort study examined incisional hernia repair from 2007 to 2013 in women of childbearing age, registered prospectively in the Danish Ventral Hernia Database. All women with a subsequent pregnancy were included, and a 1:3 propensity-score matched group of women with an incisional hernia repair without a subsequent pregnancy. A prospective follow-up was conducted, including a validated questionnaire. The primary outcome was recurrence, and the secondary outcome was chronic pain from the operated site. RESULTS In total, 124 (70.5%) women responded, 47 and 77 women with and without a subsequent pregnancy, respectively. The 5-year cumulative incidence of recurrence was 41.0% (95% confidence interval 32.0%-49.9%). After adjustment for potential confounders, subsequent pregnancy was independently associated with recurrence (hazard ratio 1.83, 95% confidence interval 1.02-3.29, p = 0.044). Twenty-six (21.0%) women reported chronic pain (moderate, n = 21; severe, n = 5) with no difference between women with and without a subsequent pregnancy. Hernia recurrence, higher body mass index, and smoking were associated with chronic pain. CONCLUSION Pregnancy following incisional hernia repair was associated with an increased risk of recurrence, but not with chronic pain.

Abstract
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.

Abstract
Aim: We examined characteristics of early sacubitril/valsartan users in a large US electronic health records database. Patients & methods: We identified three cohorts of patients with heart failure (HF): sacubitril/valsartan patients with a prior HF diagnosis; patients with HF with reduced ejection fraction; and patients with HF treated with an angiotensin-converting enzyme inhibitor or angiotensin II receptor blocker and a β-blocker. Results: Sacubitril/valsartan patients were younger than patients in the other cohorts; the mean age of sacubitril/valsartan patients increased by 2 years in the first 15 months of marketing. Most sacubitril/valsartan patients had prior use of HF treatment. Conclusion: Overall, sacubitril/valsartan patients resembled those in the HF with reduced ejection fraction cohort, and commonly used other drugs for HF.

Abstract
BACKGROUND There is no consensus agreement on the optimal management strategy for ventral hernia in women of childbearing age. The theoretical increased risk of ventral hernia recurrence can impact management strategies. We conducted a systematic review of the literature to report the ventral hernia recurrence rate in women of childbearing age who underwent hernia repair prior to their pregnancy and propose a management algorithm. METHODS We systematically searched multiple databases including MEDLNE, PubMed, and the Cochrane Library sources from inception to August, 2017. Two reviewers independently identified 314 primary studies, assessed methodological quality, and extracted data. Quality of included studies was assessed by employing the Newcastle Ottawa quality assessment tool for cohort studies. A separate tool was utilized for assessing the methodological quality of case series. A meta-analysis of proportions was conducted of studies reporting incidence of recurrence using STATA, employing a random effects model, to calculate a pooled weighted incidence rate (with 95% confidence interval). Descriptive statistics were employed to report the findings of studies which did not report any ventral hernia recurrence. RESULTS Five retrospective studies were included in our review, enrolling a total of 14,638 female participants. Upon stratifying patients according to pregnancy status after primary hernia repair, 13,494 were found to be in the non-pregnant cohort whereas 1,144 were included in the pregnant cohort. Overall, 9% (95% CI 8-9%) of the non-pregnant patients experienced a recurrence whereas 12% (95% CI 10-15%) of patients that became pregnant subsequent to a ventral hernia repair experienced a recurrence. No major adverse events were recorded throughout the course of pregnancy. CONCLUSIONS Ventral hernias in women of childbearing age have a pooled recurrence rate of 12%. Pregnancy may be considered a risk factor for ventral hernia recurrence. Female patients of childbearing age with asymptomatic or minimally symptomatic ventral hernias that do not pose a significant strain on the patients' quality of life could be provided with the option of watchful waiting, with appropriate education of risks while discussing management.

Abstract
Umbilical hernias are most common in women than men. Pregnancy may cause herniation or render a preexisting one apparent, because of progressively raised intra-abdominal pressure. The incidence of umbilical hernia among pregnancies is 0.08%. Surgical algorithm for a pregnant woman with a hernia is not thoroughly clear. There is no consensus about the timing of surgery for an umbilical hernia in a woman either who is already pregnant or planning a pregnancy. If the hernia is incarcerated or strangulated at the time of diagnosis, an emergency repair is inevitable. If the hernia is not complicated, but symptomatic an elective repair should be proposed. When the patient has a small and asymptomatic hernia it may be better to postpone the repair until she gives birth. If the hernia is repaired by suture alone, a high risk of recurrence exists during pregnancy. Umbilical hernia repair during pregnancy can be performed with minimal morbidity to the mother and baby. Second trimester is a proper timing for surgery. Asymptomatic hernias can be repaired, following childbirth or at the time of cesarean section (C-section). Elective repair after childbirth is possible as early as postpartum of eighth week. A 1-year interval can give the patient a very smooth convalescence, including hormonal stabilization and return to normal body weight. Moreover, surgery can be postponed for a longer time even after another pregnancy, if the patients would like to have more children. Diastasis recti are very frequent in pregnancy. It may persist in postpartum period. A high recurrence risk is expected in patients with rectus diastasis. This risk is especially high after suture repairs. Mesh repairs should be considered in this situation.

Abstract
BACKGROUND Prevalence, management, and risk of emergency operation for primary ventral or groin hernia in pregnancy are unknown. The objective of this study was to estimate the prevalences of primary ventral or groin hernia in pregnancy and the potential risks for elective and emergency repair. METHODS This single-institutional retrospective study included all pregnant women attending one or more prenatal consultations at Hvidovre Hospital, Denmark, during a 3-year period. Patients' medical records were electronically retrieved. A free-text search algorithm and subsequent manual review was conducted to identify patients registered with a primary ventral or groin hernia in pregnancy. Follow-up was conducted by review of medical record notes within the Capital Region of Denmark supplemented with structured telephone interviews on indication. RESULTS In total, 20,714 pregnant women were included in the study cohort. Seventeen (0.08%) and 25 (0.12%) women were registered with a primary ventral and groin hernia, respectively. None underwent elective or emergency repair in pregnancy, and all had uncomplicated childbirth. In 10 women, the groin bulge disappeared spontaneously after delivery. During postpartum follow-up of median 4.4 years (range 0.2-6.0 years), five (0.02%) and four (0.02%) underwent elective primary ventral and groin hernia repair, respectively. CONCLUSION 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.
