Despite technological advances, the long-term outcomes of endovascular aortic aneurysm repair (EVAR) are still debatable. Although most endograft failures after EVAR can be corrected with endovascular techniques, open conversion may still be required. A 70-year-old male patient presented at the emergency unit with abdominal pain. Twice, in the third and fourth years after the first repair, a stent graft had been placed over a non-adhesive portion of the stent graft due to type Ia endoleaks. In the most recent admission, a CT scan showed type III endoleak and ruptured aneurysm sac...

Peritoneal adhesions develop after abdominal surgery, trauma or intraperitoneal infections, and have important consequences. The deposition of peritoneal fibrin is a common pathophysiological pathway for the formation of adhesions. Here, we aimed to examine the effects of fibrin-induced cytokine production on peritoneal mesothelial cells (PMCs), and to block the effects of fibrin using an integrin-linked kinase (ILK) inhibitor, QLT-0267. PMCs were cultured from the enzymatic disaggregation of rat omentum. After the PMCs were covered with fibrin, the expression of IL-1β, IL-6, TNFα and VEGF-A increased...

The extracellular matrix (ECM) is not only an integral structural molecule, but is also critical for a wide range of cellular functions. The glycoprotein tenascin-X (TNX) predominates in the ECM of tissues like skin and regulates tissue structure through anti-adhesive interactions with collagen. Monogenic TNX deficiency causes painful joint hypermobility and skin hyperelasticity, symptoms characteristic of hypermobility-Ehlers Danlos Syndrome (hEDS). hEDS patients also report consistently increased visceral pain and gastrointestinal (GI) dysfunction...

BACKGROUND: A variety of surgical techniques exist to manage long-gap esophageal atresia (LGEA), including gastric pull-up (GPU), colonic interposition (CI), jejunal interposition (JI), and distraction lengthening. Salvage reconstruction for late failure of any conduit type is a complex surgical problem fraught with technical difficulty and significant risk. Jejunal interposition can be used as a salvage procedure in the management of LGEA. However, the opposing requirements of conduit length and adequate perfusion make the procedure technically challenging...

Cystic intestinal pneumatosis (CIP) is the presence of gas bubbles inside the wall of the intestine. In literature it has been reported to be associated with a variety of clinical conditions such as: superior mesenteric ischemia, intestinal perforation, bowel necrosis, infections which can cause mucosal alterations and therefore increasing its permeability, necrotizing enterocolitis in babies, trauma, intestinal obstruction, autoimmune and pulmonary pathologies. Its presence is usually documented by radiological techniques such as abdominal X-ray, CT scan and endoscopy and are usually characterized by the typical pattern of gas bubbles in the wall of the intestine...

Liver abscesses (LA) in cattle negatively affect feedlot performance by decreasing ADG, feed intake, and G:F ratio. Abscessed livers are condemned and abdominal adhesions associated with LA can result in extensive carcass trimming during harvest, further compounding adverse economic impact. Given regulatory changes pertaining to the use of in-feed antibiotics in cattle production, there is growing interest in alternatives to antibiotics for LA control. The objective of this study was to evaluate the use of antioxidants, crystalline ascorbate and alpha tocopherol acetate, for mitigation of LA in feedlot cattle...

Purpose: Incisional hernia repair is an unsuccessful field of surgery, with long-term recurrence rates reaching up to 50% regardless of technique or mesh material used. Various implants and their positioning within the abdominal wall pose numerous long-term complications that are difficult to treat due to their permanent nature and the chronic foreign body reaction they trigger. Materials mimicking the 3D structure of the extracellular matrix promote cell adhesion, proliferation, migration, and differentiation...

BACKGROUND Although perineal hernia (PH) is considered a surgery-related complication after abdominoperineal excision, the optimal therapeutic option for PH remains controversial. CASE REPORT The first case involved a 72-year-old man in whom PH was diagnosed 6 months after surgery. Laparoscopic findings revealed moderate adhesion at the pelvic floor, and a perineal approach was added. The pelvic floor defect was repaired by composite mesh. Combined laparoscopic surgery with a perineal approach was effective...

Splenic rupture following colonoscopy is rare, first reported in 1974, with incidence of 1-21/100,000. It is critical to anticipate splenic trauma during colonoscopy as one of the causes of abdominal pain after colonoscopy especially when located in the left upper quadrant or left shoulder. Postoperative adhesions is a predisposing factor for splenic injury, and management is either operative or nonoperative, based on hemodynamic stability and/or extravasation which can be seen on contrast-enhanced CT scan of the abdomen...

Complete small bowel obstruction (SBO) is a common surgical emergency often resulting from adhesive bands that form following iatrogenic peritoneal injury. Rarely, adhesive SBO may arise without previous intra-abdominal surgery through other modes of peritoneal trauma. We present the case of a male evaluated in the emergency department for a closed-loop small bowel obstruction due to an adhesive band that likely formed after blunt abdominal trauma over two decades earlier. We review the epidemiology, pathophysiology, and treatment options for similar cases of adhesive SBO...

BACKGROUND: Intra-abdominal adhesions are a major cause of morbidity after abdominal or gynecologic surgery. However, knowledge about the pathogenic mechanism(s) is limited, and there are no effective treatments. Here, we investigated a mouse model of bowel adhesion formation and the effect(s) of an Federal Drug Administration-approved drug (trametinib) in preventing adhesion formation. MATERIALS AND METHODS: C57BL/6 mice were used to develop a consistent model of intra-abdominal adhesion formation by gentle cecal abrasion with mortality rates of <10%...

Postoperative adhesions are very common complications after general abdominal surgery. Although adhesiolysis has been proven effective in eliminating the preexisting adhesions, the new trauma caused by surgical lysis can induce recurrent adhesion. The prevention of recurrent adhesion after adhesiolysis is more difficult because the injury is more severe and adhesion mechanism is more complicated compared with the primary adhesion. In this study, a thermoresponsive hydrogel contained galactose modified xyloglucan (mXG) and hydroxybutyl chitosan (HBC) was developed as a barrier device for recurrent adhesion prevention after adhesiolysis due to its injectability and spontaneous gelling behaviors at the body temperature without any chemical reactions or extra driving factors...

Aim: Angiotensin-II (Ang-II) is the main effector peptide of the renin-angiotensin system (RAS) and promotes leukocyte adhesion to the stimulated endothelium. Because RAS activation and Ang-II signaling are implicated in metabolic syndrome (MS) and abdominal aortic aneurysm (AAA), we investigated the effect of Ang-II on CXCL16 arterial expression, the underlying mechanisms, and the functional role of the CXCL16/CXCR6 axis in these cardiometabolic disorders. Methods and Results: Results from in vitro chamber assays revealed that CXCL16 neutralization significantly inhibited mononuclear leukocyte adhesion to arterial but not to venous endothelial cells...
