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...

REVIEW
Shilpa Sharma, Devendra K Gupta
PURPOSE: Surgical techniques for esophageal replacement (ER) in children include colon interposition, gastric tube, gastric transposition, and jejunal interposition. This review evaluates the merits and demerits of each. METHOD: Surgical techniques, complications, and outcome of ER are reviewed over last seven decades. RESULTS: Colon interposition is the time-tested procedure with minimal and less serious complications. Long-term complications include reflux, halitosis, colonic segment dilatation, and anastomotic stricture, sometimes requiring surgical interventions especially for dilatation and reflux...

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...

BACKGROUND: Acinetobacter baumannii has emerged as an increasingly important and successful opportunistic human pathogen due to its ability to withstand harsh environmental conditions, its characteristic virulence factors and quick adaptability to stress. METHODS: We developed a clinically relevant murine model of A. baumannii traumatic wound infection to determine the effect of local wound environment on A. baumannii virulence. Mice underwent rectus muscle crush injury combined with ischemia created by epigastric vessel ligation, followed by A...

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...

BACKGROUND: Chronic mesenteric ischemia (CMI) is a rare disease; however, symptomatic CMI has a risk of acute exacerbation without timely revascularization. CASE PRESENTATION: A 54-year-old man who had had postprandial pain for 6 months was admitted to our hospital because of vomiting and diarrhea. Although the celiac and superior mesenteric arteries were occluded at the proximal portion, contrast enhancement of the bowel wall was good in contrast-enhanced computed tomography (CECT)...

Ischaemic colitis is the most common form of intestinal ischaemia and is more common in the elderly and in the people having risk factors for colonic ischaemia. Colonoscopy procedure itself is a rare cause of ischaemic colitis. Fewer than 20 cases of ischaemic colitis caused by colonoscopy procedure have been reported in the english literature till date. This patient presented to us within hours of routine colonoscopy with rectal bleeding and lower abdominal pain. On repeat colonoscopy, the patient had mucosal oedema and ulcerations in the descending colon and sigmoid colon...

OBJECTIVE: Total small-intestinal volvulus with malrotation (TSIVM) classically presents in the neonatal period; it occurs much less frequently in the adult and is often misdiagnosed. Prognosis is directly related to the degree and duration of intestinal ischemia. Our goal is to describe our experience with TSIVM in the adult, to identify any specific findings and to discuss its management. METHOD: Eleven patients who had undergone surgery for TSIVM at three centers between 1992 and 2012 were included...

Objective. Decreased cardiac function after resuscitation from cardiac arrest (CA) results from global ischemia of the myocardium. In the evolution of postarrest myocardial dysfunction, preferential involvement of any coronary arterial territory is not known. We hypothesized that there is no preferential involvement of any coronary artery during electrical induced ventricular fibrillation (VF) in piglet model. Design. Prospective, randomized controlled study. Methods. 12 piglets were randomized to baseline and electrical induced VF...

Hydrophilic polymer coating of medical devices serves to lubricate the device and prevent device-related complications. The coating can be mechanically disrupted and result in downstream injury via presumed thromboembolism. This process has been reported in the brain, heart, lung, and skin, and has been replicated through animal studies and in vitro histologic processing of the polymer coating. We report the first description of hydrophilic polymer-associated ischemic enterocolitis in a series of 7 specimens (small bowel=2, colon=4, aortic thrombus=1) from 3 patients...

PURPOSE OF REVIEW: To provide an update on the epidemiology, pathophysiology, clinical presentation, and management of colonic ischemia. RECENT FINDINGS: Formerly regarded as a rare cause of lower gastrointestinal hemorrhage, colonic ischemia is now recognized to be the most common manifestation of intestinal vascular compromise. In contrast to ischemic events in the small intestine wherein thrombotic and embolic events predominate, colonic ischemia typically results from a global reduction in blood flow to the colon and no occlusive lesion(s) are evident...

Colonoscopy is one of the most widely used procedures in medical practice for the diagnosis and treatment of many benign and malignant diseases of the colorectal tract. Colonscopy has become the reference procedure for screening and surveillance of colorectal cancer. The overall rate of adverse events is estimated to be about 2.8 per 1,000 procedures, while complications requiring hospitalization are about 1.9 per 1,000 colonoscopies. Mortality from all causes and colonoscopy-specific mortality are estimated to be 0...

We report a 41-year-old woman who developed histology- and colonoscopy-proven ischemic colitis with the use of naratriptan not exceeding the maximum 2 doses a day and 3 days per week and without a known medical or cardiovascular history. By exclusion of other causes of colonic ischemia, naratriptan was considered the sole causal agent. Discontinuation of naratriptan resulted in a complete clinical recovery. To date, our patient is the youngest known patient to develop ischemic colitis on isolated naratriptan in the setting of no known medical risk factors or predisposing medical condition...
