INTRODUCTION: Surgery, a crucial therapeutic modality in the treatment of solid tumors, can induce sterile inflammatory processes which can result in metastatic progression. Liver ischemia and reperfusion (I/R) injury, an inevitable consequence of hepatic resection of metastases, has been shown to foster hepatic capture of circulating cancer cells and accelerate metastatic growth. Efforts to reduce these negative consequences have not been thoroughly investigated. Drag reducing polymers (DRPs) are blood-soluble macromolecules that can, in nanomolar concentrations, increase tissue perfusion, decrease vascular resistance and decrease near-wall microvascular concentration of neutrophils and platelets thereby possibly reducing the inflammatory microenvironment...

INTRODUCTION: Chronic constipation is very common in elderly patients. As a result of this situation fecaloma is also frequently seen at these ages. However, the stercoral perforation caused by fecaloma is a rare situation to occur. The rectosigmoid colon is the most affected colonic segment. It is seen in older patients with concomitant diseases and a low quality of life. PRESENTATION OF CASE: Here in this case, we have to report an 83 - year-old male patient who came to the emergency room with complaints of abdominal pain and constipation for two days...

BACKGROUND: Anastomotic leak is a devastating postoperative complication following rectal anastomoses associated with significant clinical and oncological implications. As a result, there is a need for novel intraoperative methods that will help predict anastomotic leak. METHODS: From 2011 to 2014, patient undergoing rectal anastomoses by colorectal surgeons at our institution underwent prospective application of intraoperative flexible endoscopy with mucosal grading...

Idiopathic myointimal hyperplasia of mesenteric veins causes chronic ischemic mucosal injury with segmental strictures that mimic inflammatory bowel disease and nonocclusive ischemic colitis. It is characterized by myointimal proliferative changes that narrow the lumina of veins combined with ischemic injury and ulcers. Most cases reported to date have been diagnosed following surgical resection. The aim of this study was to determine whether mucosal changes of idiopathic myointimal hyperplasia of mesenteric veins are sufficiently sensitive and specific to allow its recognition in biopsy material...

Necrotizing enterocolitis (NEC) is an inflammatory process, characterized by intestinal necrosis of variable extension, leading to perforation, generalized peritonitis and death. The classical pathogenetic theory focuses on mucosal damage related to a stress induced intestinal ischemia leading to mucosal injury and bacterial colonization of the wall. A more recent hypothesis emphasizes the role of immaturity of gastrointestinal and immune system, particularly of the premature, responsible of bowel wall vulnerability and suffering...

Sigmoid volvulus (SV) is a rare colonic obstruction in which the sigmoid colonwraps around itself. The principal strategy for the treatment of uncomplicated SV is emergency endoscopic detorsion, while emergency surgery is needed in complicated SV with bowel gangrene, bowel perforation, peritonitis, or unsuccessful endoscopic treatment. In the endoscopic examination of SV, endoscopic detorsion is performed if the bowels are viable, while emergency surgery is needed if the bowels are gangrenous. However, the treatment approach is not clear when endoscopic examination reveals borderline bowel ischemia, and in this short report, the possible treatment strategies are discussed...

This study focuses on two inflammatory diseases, viz., "diabetes mellitus (DM)" that causes serious complications such as retinopathy, nephropathy, and neuropathy, and "ischemic colitis" which is evoked by DM. Ischemic colitis originates from the reduction in mesenteric blood flow to the colon with existence of the occlusive or non-occlusive reasons. Our study objective was to provide early diagnostic approach for ischemic colitis in streptozotocin (STZ)-induced diabetic rats. Sprague-Dawley rats were divided into four groups: (i) control use of 0...

INTRODUCTION: Retrocecal hernia is a rare type of pericecal hernia. Because it is difficult to diagnose preoperatively, it is often treated with emergency operation. CASE PRESENTATION: An 83-year-old male patient experienced sudden abdominal pain. Marked small bowel dilatation and intestinal obstruction were detected by abdominal computed tomography (CT). An enhanced CT scan also revealed a trapped cluster of small bowel loops behind the cecum and ascending colon...

Non-occlusive mesenteric ischemia (NOMI) is a severe pathological condition characterized by signs and symptoms of bowel obstruction, intestinal necrosis resulting from acute and/or chronic inadequate blood perfusion, in the absence of an organic vascular obstruction detectable by imaging techniques. A 64 years old man case with a history of Parkinson's disease in high-functioning levodopa treatment is presented. Clinical and radiological signs of intestinal obstruction were observed. He underwent surgical operation with total colectomy and terminal ileostomy for generalized secondary peritonitis due to perforation of sigmoid colon...

Colon ischemia following aortic reconstruction is a severe complication with an incidence of 1% to 2% of the operated patients; this infrequent complication will be lethal for nearly half of these patients. Commonly, colon ischemia may be an intraoperative observation or an early postoperative finding. However, in the case presented here, sigmoid rupture and small and large intestine communication was revealed 3 months following repair of the abdominal aorta. A 71-year-old man, following open repair of an abdominal aortic aneurysm, went home on the fifth postoperative day...

Vedolizumab (VDZ) inhibits α4β7 integrins and is used to target intestinal immune responses in patients with inflammatory bowel disease, which is considered to be relatively safe. Here we report on a fatal complication following VDZ administration. A 64-year-old female patient with ulcerative colitis (UC) refractory to tumor necrosis factor inhibitors was treated with VDZ. One week after the second VDZ infusion, she was admitted to hospital with severe diarrhea and systemic inflammatory response syndrome (SIRS)...

BACKGROUND: Survivin, a member of the inhibitor of apoptosis protein (IAP) family, regulates mitosis and chromosome segregation. The expression of survivin proceeds during embryonic development and in addition has already been demonstrated in cancer cells. However, there is also evidence of survivin expression in differentiated tissues, including the gastro-intestinal tract of adult rats. A study with human colon specimens exhibited survivin in most basal crypt epithelial cells of normal mucosa...
