Abdominal wall hernia

INTRODUCTION: Abdominal wall blocks, in conjunction with multimodal analgesia, have demonstrated efficacy in providing post-operative analgesia, reducing opioid requirements in patients undergoing inguinal hernia repair. The inguinal region is primarily innervated by the ilioinguinal nerve (IIN) and iliohypogastric nerve (IIH). Posterior transverse abdominis plane block (pTAP) and fascia transversalis plane block (TFP) have been observed to reliably block IIN and IIH. We hypothesized that posterior TAP block (pTAP) owing to its potential paravertebral spread will provide better post-operative analgesia than TFP block in patients undergoing unilateral open inguinal hernia repair...

Development of a tear in the abdominal wall allowing for protrusion of intra-abdominal contents is known as a hernia. This can cause pain, discomfort, and may need surgical repair. Hernias can affect people of any age or demographic. In the USA, over 1 million hernia repair procedures are performed each year. During these surgeries, it is common for a mesh to be utilized to strengthen the repair. Different techniques allow for the mesh to be placed in different anatomical planes depending on hernia location and approach...

OBJECTIVE: The precise indications for employing the anterior component separation technique (ACST) and the Transversus Abdominis Release (TAR) in abdominal wall reconstruction (AWR) remain uncertain, despite the undeniable value of both techniques. The aim of this study was to analyze the anterior fascial closure rate, postoperative wound morbidity, and hernia recurrence rate for both procedures according to the algorithm used for complex AWR. METHODS: A retrospective analysis of prospectively collected data was carried out...

INTRODUCTION: Combined ventral hernia repair and abdominoplasty treat risk factors such as high body mass index and weak abdominal musculature, providing excellent intraoperative exposure and improved patient outcomes. Unfortunately, a combination of traditional procedures is unfeasible as the umbilical blood supply would be compromised, leading to increased umbilical necrosis risk. This narrative review aimed to identify new techniques and solidify evidence in preserving umbilical blood supply and associated level of evidence...

PURPOSE: Stress urinary incontinence (UI) often develops after radical prostatectomy for prostate cancer, and in those patients with moderate-to-severe stress UI an artificial urinary sphincter (AUS) is implanted. Inguinal hernias (IHs) often occur after radical prostatectomy. As the prevalence of AUS implantation increases, it is possible to encounter patients with IHs undergoing AUS implantation (IHA). This study investigated our treatment and discussed an appropriate approach for IHAs...

Appendicitis is a well-known and highly common surgical emergency disease, yet it presents with a wide variety of manifestations. This is a case report of a 47-year-old female who presented with a complaint of having constant crampy right lower abdominal pain for two weeks. The patient reported having a sudden onset of symptoms that went with the typical picture of acute appendicitis that occurred two weeks ago. Our pre-op workup was inconclusive; therefore, we planned to go for a diagnostic laparoscopy, where surprisingly, the appendix was long, inflamed, and attached to the posterior wall of the cecum...

BACKGROUND: Reconstruction of the abdominal wall in patients with prune-belly syndrome (PBS) following previous intra-abdominal procedures is a challenging problem with a high incidence of revision due to persistent bulging or herniation. The abdominal wall flaccidity not only produces a severe psychological and aesthetic discomfort for the patient but often determines functional disabilities, including inability to cough properly, impaired bowel and bladder function, and delay in posture and balance...

INTRODUCTION AND IMPORTANCE: OEIS complex is a rare and complex anomaly of the genitourinary and intestinal tract. It includes Omphalocele, Exstrophy of cloaca, Imperforate anus and Spinal defects. PRESENTATION OF CASE: We are reporting a case of OEIS complex. CLINICAL DISCUSSION: Cloacal exstrophy is considered the most severe ventral abdominal wall defect. Diagnosis is primarily antenatal based on the presenting features on ultrasonography...

PURPOSE: Parastomal hernia poses a challenging problem in the field of hernia surgery. The high incidence and recurrence rates of parastomal hernia necessitate surgeons to enhance surgical techniques and repair materials. This study aimed to develop a rat model of parastomal hernia by inducing various types of defects on the abdominal wall with colostomy. This established method has potential for future studies on parastomal hernia. METHODS: In this study, 32 male rats were included and randomly divided into four groups: the oblique abdominis excision (OE), oblique abdominis dissection (OD), rectus abdominis excision (RE), and rectus abdominis dissection (RD) groups...

PURPOSE: Surgical repair of complex abdominal wall hernias remains technically demanding and is widely recognized as a risk factor for unfavorable outcomes with high recurrence and morbidity rates. The objective is to assess short- and long-term complications after open intraperitoneal onlay mesh (IPOM) repair combined with bilateral anterior component separation (ACS) for large and difficult incisional hernias, alongside evaluating hernia recurrence rates. METHODS: This retrospective analysis utilized data sourced from Hospital electronic health records and a prospective database at an academic tertiary referral center...

BACKGROUND: Abdominal wall reconstruction requires extensive dissection of the abdominal wall, exposure of the retroperitoneum, and aggressive chemoprophylaxis to reduce the risk of thromboembolic complications. The need for early anticoagulation puts patients at risk for bleeding. We aimed to quantify postoperative blood loss, incidence of transfusion and reoperation, and associated risk factors in patients undergoing complex abdominal wall reconstruction. METHODS: All patients underwent a posterior component separation with transversus abdominis release and placement of retromuscular mesh for ventral hernias <20 cm wide and were enrolled in a clinical trial assessing the utility of trans-fascial mesh fixation...

INTRODUCTION: The objective of this study was to perform a systematic review and meta-analysis to summarize various approaches in performing minimally invasive posterior component separation (MIS PCS) and ascertain their safety and short-term outcomes. METHODS: A systematic literature searches of major databases were conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines to identify studies that provided perioperative characteristics and postoperative outcomes of MIS PCS...

BACKGROUND: Flank and lumbar hernias (FLH) are challenging to repair. This study aimed to establish a reproducible management strategy and analyze elective flank and lumbar repair (FLHR) outcomes from a single institution. METHODS: A prospective analysis using a hernia-specific database was performed examining patients undergoing open FLHR between 2004 and 2021. Variables included patient demographics and operative characteristics. RESULTS: Of 142 patients, 106 presented with flank hernias, and 36 with lumbar hernias...

INTRODUCTION: Incisional hernia (IH) is a prevalent and potentially dangerous complication of abdominal surgery, especially in high-risk groups. Mesh reinforcement of the abdominal wall has been studied as a potential intervention to prevent IHs. Randomised controlled trials (RCTs) have demonstrated that prophylactic mesh reinforcement after abdominal surgery, in general, is effective and safe. In patients with abdominal aortic aneurysm (AAA), prophylactic mesh reinforcement after open repair has not yet been recommended in official guidelines, because of relatively small sample sizes in individual trials...

INTRODUCTION: Parastomal hernia (PSH) is the most common and challenging complication after stoma creation, with an estimated 50% incidence 2 years after the index surgery. Mesh repair is the treatment of choice. Laparoscopic and/or robotic approaches allow acceptable outcomes. MATERIALS AND METHODS: A systematic literature review from January 2012 to November 2023 was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement...

PURPOSE: Risk of total extraperitoneal hernia repair (TEP) in patients with previous lower abdominal surgery (PLAS) is still debated. The present study was designed to assess the rate of conversion in TEP for inguinal hernia stratified by type of PLAS. METHODS: Variables on patients undergoing TEP inguinal hernia repair at our center were prospectively collected between July 2012 and May 2018. Patients with PLAS were compared to patients without PLAS. Furthermore, the most frequent subtypes of PLAS were defined and TEP conversion rate was stratified according to type of PLAS...

BACKGROUND: The majority of small bowel obstructions (SBO) are caused by adhesion due to abdominal surgery. Internal hernias, a very rare cause of SBO, can arise from exposed blood vessels and nerves during pelvic lymphadenectomy (PL). In this report, we present two cases of SBO following laparoscopic and robot-assisted lateral lymph node dissection (LLND) for rectal cancer, one case each, of which obstructions were attributed to the exposure of blood vessels and nerves during the procedures...

Spontaneous bowel evisceration from a ruptured, long-standing abdominal wall hernia is a very rare complication with significant morbidity and mortality, usually occurring in incisional or recurrent groin hernias. In this case report, we elucidate an unexpected scenario of spontaneous incisional hernia rupture leading to bowel evisceration, detailing the clinical presentation, diagnostic workup, and surgical management. By highlighting this rare complication, we emphasise the significance of vigilance in monitoring hernia patients and the necessity of expedited surgical intervention to prevent complications, optimise outcomes, and minimise morbidity...

PURPOSE: Intraoperative fascial traction (IFT) for the treatment of large ventral hernias and loss of domain (LOD) hernias is a promising tool in abdominal wall surgery. However, little is known about the extent of gain in myofascial advancement especially for the anterior rectus sheath. We, therefore, used a cadaveric model to determine the medialization during IFT. METHODS: 4 fresh frozen specimens were used. Retromuscular preparation was carried out followed by IFT with diagonal vertical traction for 30 min...

The management of giant inguinoscrotal hernias remains a challenge as a result of the loss of the intra-abdominal domain from long-standing hernia contents within the scrotum. Multiple techniques have been described for abdominal wall relaxation and augmentation to allow the safe return of viscera from the scrotum to the intraperitoneal cavity without adversely affecting cardiorespiratory physiology. Preoperative progressive pneumoperitoneum, phrenectomy, and component separation are but a few common techniques previously described as adjuncts to the management of these massively large hernias...
