Abdominal wall reconstruction (AWR) is a surgical procedure performed to address various conditions such as hernias, incisional hernias, and complex abdominal wall defects. Mesh fixation plays a crucial role in providing mechanical reinforcement to the weakened abdominal wall during AWR. Traditionally, suturing has been the preferred method for mesh fixation; however, adhesion techniques using tissue adhesives or glues have gained attention as an alternative approach. This systematic review aims to compare suturing and adhesion techniques for mesh fixation in AWR and assess their effectiveness in preventing hernia recurrence...

METHODS: A total of 36 SD rats were randomly divided into normal, model, and moxibustion groups, with 12 rats in each group. The IBS-D model was established by maternal separation + acetic acid stimulation + chronic restraint...

This study aims to investigate the mechanism of Linderae Radix water extract(LRWE) in the prevention and treatment of diarrhea-predominant irritable bowel syndrome(IBS-D) based on serum metabolomics. Eighteen 2-week-old male SD rats were randomized into control, IBS-D model, and LRWE groups. The rats in other groups except the control group received gavage of senna concentrate combined with restraint stress for the modeling of IBS-D. The rats in the LRWE group were administrated with LRWE(5.4 g·kg~(-1)) by gavage, and those in the control and IBS-D model groups with an equal volume of distilled water for a total of 14 days...

Surgery is the only treatment for parastomal hernia (PH). When possible, stoma closure is the best way to manage this type of hernia, however, whether to perform it in a single approach with abdominal wall reconstruction (AWR) is still debatable. A 58-year-old woman with a type IV PH with loss of domain was submitted to preoperative optimization [botulinum toxin type A and progressive pneumoperitoneum (PPP)], followed by simultaneous stoma closure and AWR. Hospital discharge was on the eighth day with no complications...

INTRODUCTION: Ventral wall hernia often causes significant morbidity and requires complex abdominal wall reconstruction (AWR). This study aims to determine whether subcutaneous abdominal fat thickness (AFT) measured with preoperative CT scans could predict postoperative outcomes in patients undergoing AWR. METHODS: A retrospective cohort study was conducted on all patients who underwent AWR at our institution between 2009 and 2021, with a minimum follow-up of 12 months...

INTRODUCTION: Abdominal wall reconstruction (AWR) utilizes advanced myofascial releases to perform complex ventral hernia repair (VHR). The relationship between the performance of AWR and disparities in insurance type is unknown. METHODS: The Abdominal Core Health Quality Collaborative was queried for adults who had undergone an elective VHR between 2013 and 2020 with a hernia size ≥10 cm. Patients with missing insurance data were excluded. Comparison groups were divided by insurance type: favorable (private, Medicare, Veteran's Administration, Tricare) or unfavorable (Medicaid and self-pay)...

Tension-free abdominal wall hernia patch materials (AWHPMs) play an important role in the repair of abdominal wall defects (AWDs), which have a recurrence rate of less than 1%. Nevertheless, there are still significant challenges in the development of tailored, biomimetic, and extracellular matrix (ECM)-like AWHPMs that satisfy the clinical demands of abdominal wall repair (AWR) while effectively handling post-operative complications associated with abdominal hernias, such as intra-abdominal visceral adhesion and abnormal healing...

INTRODUCTION: Surgeons use several quality-of-life instruments to track outcomes following abdominal wall reconstruction (AWR); however, there is no universally agreed upon instrument. We review the instruments used in AWR and report their utilization trends within the literature. METHODS: This scoping review was reported according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis extension for Scoping Reviews guidelines using the PubMed, Embase, Web of Science, ClinicalTrials...

Background Complex abdominal wall hernias have proven challenging to manage, and such patients often require abdominal wall reconstruction (AWR). However, in the context of a socialist healthcare service, which is required to provide equal and fair healthcare access to all, the heavy resource burden and non-life-threatening nature of complex abdominal wall hernias mean that this patient group may not be prioritised. In this paper, we outline the significant quality of life (QoL) burden on patients requiring AWR and the importance of quality improvement projects (QIPs) in establishing and streamlining their care as a robust, transferable model across centres...

OBJECTIVE: Sacral nerve stimulation (SNS) is emerging as a novel treatment for irritable bowel syndrome (IBS). However, its effects are limited, and the underlying mechanisms remain largely unknown. MATERIALS AND METHODS: In this study, rats were divided into three groups (n = 12 rats per group): 1) the SNS group; 2) the sham SNS group (the sham group for short); and 3) the control group. The SNS and sham groups were exposed to chronic and acute stress to establish an IBS model...
