Risk Factors For Development Of Incisional Hernia Research Articles

Risk factors for incisional hernia after liver transplantation in the era of mammalian target of rapamycin inhibitors use: a retrospective study of living donor liver transplantation dominant center in Korea.

Incisional hernia (IH) is a common complication after liver transplantation (LT) with an incidence rate of 5% to 46%. This retrospective study aimed to evaluate the risk factors for IH development after LT in the era of mammalian target of rapamycin (mTOR) inhibitors use. Data on patients who underwent LT between 2015 and 2021 were retrospectively reviewed. The patients were divided into 2 groups (IH group and non-IH group) according to the postoperative occurrence of IH. We analyzed data from 878 patients during the study period, with 28 patients (3.2%) developing IH. According to multivariate analysis, body mass index exceeding 25 kg/m2 and the use of mTOR inhibitors within the first month after LT were the sole significant factors for both IH occurrence and the subsequent need for repair operations. Notably, a history of wound complications, a Model for End-stage Liver Disease score, and the timing of LT-whether conducted during regular hours or at night-did not emerge as significant risk factors for IH after LT. Our study reveals a higher incidence of IH among obese patients following LT, often requiring surgical repair, particularly in cases involving mTOR inhibitor usage within the initial month after LT. Consequently, it is crucial to exercise increased vigilance, especially in obese patients, and exercise caution when considering early mTOR inhibitor administration after LT.

SP2.1.6 A Systematic Review of the Incidence and Predictors of Incisional Hernias in Robotic Prostatectomy

Abstract Aims To conduct a systematic review of the literature to identify the incidence and predictors of incisional hernia (IH) following robotic prostatectomy; and to provide recommendations to reduce the risk factors for IH development post-operatively. Methods The review was performed adhering to PRISMA guidelines, using search terms pertaining to robotic prostatectomy and incidence of IH via electronic databases (MEDLINE, EMBASE and Cochrane database). All original peer-reviewed articles in English were assessed for inclusion and quality by two independent reviewers. A quantitative analysis was conducted to evaluate methodologies, patient demographics, and the incidence of IH following robotic prostatectomy. Results We included 18 studies with a total of 17,965 patients. Average age of patients was 61.83 years and with an average BMI of 27.35. A transperitoneal, 6 port technique was the commonest robotic approach. Main sites of herniation included supraumbilical and lateral ports. The estimated incidence of IH was 1.49% (95% CI 1.28 to 4.25). Studies examining risk factors found age, high BMI, previous hernia repair and wound infections to be contributory to IH development. Only 6 studies reported surgical repair of IH with 3 patients requiring emergency operations. 5 studies reported reduction in IH following modifications in surgical technique. Conclusions Incisional hernias following robotic prostatectomy are a rare complication which can result in high patient morbidity. Our review demonstrated a variable incidence rate with increasing age and high BMI as common potential risk factors. Prevention strategies can result in reduction of IH; however, the studies were heterogenous with inconsistent data quality.

Incisional hernia after surgical correction of abdominal congenital anomalies in infants: a systematic review with meta-analysis

Incisional hernia (IH) in children could result in life-threatening complications, including incarceration and bowel strangulation. The incidence and risk factors of IH in infants are scarcely reported. Since IH-correction may require extensive surgery and a long recovery program, identifying infants and birth defects at risk, may lead to a different approach during the primary surgery. Therefore, the aim of this review is to systematically review the available data on the incidence of IH following surgery for congenital anomalies in infants. All studies describing IH were considered eligible. PubMed and Embase were searched and risk of bias was assessed. Primary outcome was the incidence of IH, secondary outcomes were difference in IH occurrence between disease severity (complex vs simple) and closure method (SILO vs primary closure) in gastroschisis patients. A meta-analysis was performed to pool the reported incidences in total and per congenital anomaly separately. Subgroup analysis within gastroschisis articles was performed. The 50 included studies represent 3140 patients. The pooled proportion of IH was 0.03 (95% CI 0.02–0.05; I2 = 79%, p ≤ 0.01) all anomalies combined. Gastroschisis (GS) reported highest pooled proportion 0.10 (95% CI 0.06–0.17; n = 142/1273; I2 = 86%; p ≤ 0.01). SILO closure (OR 3.09) and simple gastroschisis, i.e. without additional anomalies, (OR 0.18) were of significant influence. This review reports the incidence of IH in infants with different congenital abdominal anomalies, of which gastroschisis reported the highest risk. In GS patients, complex GS and SILO closure are risk factors for IH development.
