About 20% of patients with abdominal aortic aneurysms have associated iliac aneurysms. Distal sealing during the endovascular treatment of aortic-iliac aneurysms is a challenge that has led to the emergence of several technical options to achieve this goal over the years. Internal iliac artery embolization is associated with the risk of ischemic complications, such as gluteal necrosis, lower limb neurological deficit, colonic ischemia, impotence and gluteal claudication. This article summarizes the technical options for endovascular treatment of aortoiliac aneurysms with different approaches to preserving the patency of internal iliac arteries...

BACKGROUND: Our group has previously published a retrospective review defining variables predictive of transmural bowel ischemia in the setting of pneumatosis intestinalis (PI). We hypothesize this prospective study will confirm the findings of the retrospective review, enhancing legitimacy to the predictive factors for pathologic PI previously highlighted. METHODS: Data were collected using the Research Electronic Data Capture. Forward logistic regression was utilized to identify independent predictors for pathologic PI...

OBJECTIVE: Hypogastric artery embolization (HAE) is associated with significant risk of ischemic complications. We assessed the impact of HAE on 30-day outcomes of endovascular aneurysm repair (EVAR) of infrarenal abdominal aortic aneurysms. METHODS: We queried the American College of Surgeons National Surgical Quality Improvement Program database from 2011 to 2014 to identify and to compare clinical features, operative details, and 30-day outcomes of EVAR with those of concomitant HAE with EVAR (HAE + EVAR)...

BACKGROUND: Non-occlusive mesenteric ischemia (NOMI) is ischemia of the mesentery that is caused by hypoperfusion or vasospasm without any thrombosis. NOMI is difficult to diagnose by physical examination alone. Although angiographic examination of the superior mesenteric artery (SMA) is the usual diagnostic method used, it is an invasive examination. Usually, a long range of the bowel becomes discontinuously necrotic in NOMI. Here, we report a rare case of NOMI localized in the transverse colon that was diagnosed by computed tomography (CT) angiography which is a minimally invasive examination...

OBJECTIVE: To determine whether intestinal colonization with methicillin-resistant Staphylococcus aureus (MRSA) can be the source of surgical site infections (SSIs). BACKGROUND: We hypothesized that gut-derived MRSA may cause SSIs via mechanisms in which circulating immune cells scavenge MRSA from the gut, home to surgical wounds, and cause infection (Trojan Horse Hypothesis). METHODS: MRSA gut colonization was achieved by disrupting the microbiota with antibiotics, imposing a period of starvation and introducing MRSA via gavage...

Volvulus of the intestines may involve either the small bowel or colon. In the pediatric population, small bowel volvulus is more common, while in the adult population, colonic volvulus is more often seen. The two most common types of colonic volvulus include sigmoid and cecal volvulus. Prompt diagnosis and treatment is imperative, otherwise bowel ischemia may ensue. Treatment often involves emergent surgical exploration and bowel resection.

Intramural colonic hemorrhage is rare and often secondary to trauma or anticoagulation therapy. Idiopathic intramural hemorrhages in the alimentary tract have rarely been reported. While several reports of spontaneous perforation of an intramural rectal hematoma have been published, no reports of spontaneous perforation in the ascending colon due to a hematoma have. We describe a patient with an ascending colonic perforation secondary to spontaneous intramural hemorrhage. The patient is a 35-year-old male, who presented with acute abdominal pain and no history of trauma...

BACKGROUND: Acute mesenteric ischemia is a rare affection with high related mortality. NOMI presents the most important diagnostic problems and is related with the higher risk of white laparotomy. This study wants to give a contribution for the validation of laparoscopic approach in case of NOMI. METHODS: Thirty-two consecutive patients were admitted in last 10 years in ICU of Paolo Giaccone University Hospital of Palermo for AMI. Diagnosis was obtained by multislice CT and selective angiography was done if clinical conditions were permissive...

A number of nontraumatic acute abdomen can result in peritonitis leading to sepsis. In emergent conditions, various procedures like segmentary colectomy and/or subtotal colectomy with anastomosis, Hartmann's procedure, transverse colectomy, and/or expandable metallic stent (SEMS) placement can be performed, considering the status of the patient and the facilitaties of the institution. In our study, we examined the cases diagnosed as acute abdomen without the history of trauma, which had lead to a procedure requiring colostomy...

BACKGROUND: Compared to open thoracoabdominal aortic aneurysm (TAAA) repair, hybrid repair is thought to be less invasive with better perioperative outcomes. Due to the extent of the operation and long recovery period, studying perioperative results may not be sufficient for evaluation of the true treatment effect. The aim of this study is to evaluate 1-year mortality and morbidity in patients with TAAA undergoing hybrid repair. METHODS: In a retrospective cohort study, all medical records of patients undergoing hybrid repair for TAAA at the Erasmus University Medical Center between January 2007 and January 2015 were studied...

Ogilvie's syndrome, also known as 'paralytic ileus of the colon', is characterised by pseudo-obstruction of the large intestine in the absence of any mechanical obstructing component; and presents as a massively distended abdomen. If left untreated, it may lead to bowel perforation or ischemia. Ogilvie's syndrome usually presents as a postsurgical complication, mainly due to the lack and/or restriction of movement coupled with a possible electrolyte imbalance. Here, we present a case of a pre-surgical 63-year lady, having a right hip fracture, who came with complaints of severe abdominal pain and distension for 4 days...

BACKGROUND: Intestinal malrotation is a well-known anomaly in the normal rotation process of the midgut during embryogenesis. Multiple forms are described, resulting in various positional configurations of the small bowel and colon. Replaced common hepatic artery is a rare but not anecdotic variant of the standard hepatic vascularization, associated with surgical implications. Our aim is to explain the impact of their simultaneous presence during this procedure and the difficulty in identifying them preoperatively, despite imaging...

The mammalian intestinal mucosa exhibits a spectrum of responses after acute injury and repairs itself rapidly to restore the epithelial integrity. The RNA-binding protein HuR regulates the stability and translation of target mRNAs and is involved in many aspects of gut epithelium homeostasis, but its exact role in the regulation of mucosal repair after injury remains unknown. Here we show that HuR is essential for early intestinal epithelial restitution by increasing the expression of cell division control protein 42 (Cdc42) at the posttranscriptional level...

PURPOSE: Current surgical dogma dictates that tissue ischemia and hypoxia are major contributing factors in anastomotic leak despite scant evidence. The aim of this study was to determine if tissue hypoxia is a feature of anastomotic leakage in rats following colon resection and segmental devascularization. METHODS: Rats were randomly assigned to undergo sham operation, segmental colon devascularization alone, colectomy alone, or segmental devascularization plus colectomy...
