Colonic ischaemia, commonly referred to as ischaemic colitis, is the most common type of intestinal ischaemia. The term "ischaemic colitis" was used by Marston (1966) with three typical patterns of injury described: transient reversible ischaemia, ischaemic ulcers with stricturing, and gangrenous ischaemic colitis. Dominant presenting symptoms were colicky abdominal pain, vomiting, bloody diarrhea, and hematochezia. Patients often have minimal signs on clinical examination. Most patients were diagnosed at colonoscopy. Two regions that are believed to be anatomically vulnerable to ischemic disease are "Griffith's point", at the splenic flexure and "Sudeck's critical point", of the Drummond marginal artery. Clinically, ischaemic colitis is classified as non-gangrenous or gangrenous. Non-gangrenous ischaemic colitis involves the mucosa and submucosa and accounts for 80-85 percent of all cases of ischaemic colitis. Non-gangrenous ischaemic colitis is further subclassified into transient, reversible ischaemic colitis with a less severe form of injury and chronic, non-reversible ischaemic colitis, which includes chronic colitis and stricture and has a more severe form of injury. Gangrenous ischaemic colitis accounts for the remaining 15-20 percent of cases and manifests as the most seve-re form of injury. It includes acute fulminant ischaemia with transmural infarction that may progress to necrosis and death. Specific indications for operation include peritonitis, perforation, recurrent fever or sepsis, clinical deterioration in patients refractory to me-ical management. Relative indications include fulminant colitis, massive hemorrhage, chronic protein losing colopathy, and symptomatic ischemic stricture.

We experienced two autopsy cases of fulminant sepsis due to anaerobes. Case 1: A 67-year-old female with uncontrolled diabetes mellitus (DM) was admitted to a hospital because of sudden onset of mid-abdominal pain. She was diagnosed with infectious colitis and given a laxative and an enema. However, 9h later, her blood pressure suddenly dropped with metabolic acidosis, and she died 20 h after admission. Autopsy revealed massive pneumohemia and a dark-brown colored mucosal surface from the terminal ileum to the sigmoid colon. Histopathological findings were compatible with marginal ischemic colitis. Anaerobes were positive in blood culture. Case 2: A 53-year-old male with alcoholic liver cirrhosis (LC) was found dead in his room. He had been alive 24 h before the discovery, but postmortem changes appeared to accelerate more rapidly than usual cases. Autopsy revealed severe LC with muddy ascites and many Gram-negative rods in several organs. These cases suggest the possibility of sepsis as causes of death, especially in immuno-compromised hosts when unexplained putrefactive changes are seen on forensic autopsy.

The aim of this study was to describe the technique and report our single center experience of abdominal aortic aneurysm (AAA) open surgical repair over the last 17 years. From 1993 to 2010, a total of 4347 open surgical procedures for repair of AAA were performed in our center. The details of 3857 (88.7%) patients undergoing infrarenal AAA open repair were analyzed; mean age at the time of surgery was 71.8 years ranging from 58 to 89 years. Among all repairs, 23.7% (914) were performed in women and 24.3% (937) in octogenarians; 3587 (93.0%) procedures were performed for degenerative aneurysms, 146 (3.8%) for inflammatory aneurysms, 100 (2.6%) for dissecting aneurysms, and 19 (0.5%) for other pattern of disease. In 162 cases (4.2%) surgery was performed for ruptured aneurysm. In most cases (N.=2596; 67.3%) infrarenal AAA open repair was performed by means of aorto-aortic bypass using a tube graft. A total of 1261 patients were treated using a bifurcated graft: 417 (33.1%) aorto-iliac bypasses, 530 (42.0%) aorto-femoral bypasses and 314 (24.9%) aorto-iliac-femoral bypasses were performed. In elective aorto-aortic bypass, mean aortic clamping time was 21.3+6.7 minutes. The average duration of the procedure was 126+84 minutes (range, 42-410 minutes). Mean intraoperative bleeding was 803.4+422.7 mL (range 250-3,100). Overall intraoperative mortality was 0.2%. Intraoperative mesenteric ischemia was observed in 3% of cases, all treated with inferior mesenteric artery reimplantation. The rate of intraoperative lower limbs ischemia was 2.2%. One intraoperative acute type A aortic dissection occurred. The overall 30-day mortality was 0.6%. Permanent renal function impairment occurred in 4.3% of cases. The rate of pulmonary complications was 9.8%. Other complications were myocardial infarction, congestive heart failure, late ischemic colitis, late leg ischemia, wound infection, urinary tract infection, and sepsis. Although endovascular techniques have emerged as a less invasive alternative to open repair, short- and long-term outcomes associated to the surgery of infrarenal AAAs remain satisfactory for a large range of patients.

Posterior reversible encephalopathy syndrome (PRES) is a clinico-neuroradiological syndrome characterized by various symptoms of neurological disease. It has commonly been reported in association with acute hypertension, pre-eclampsia, eclampsia, sepsis, and exposure to immunosuppressants. Here, we report on a normotensive woman who developed a severe frontal headache, visual disturbances, and hypertension 3 days after undergoing an emergency laparotomy for ischemic colitis during which she suffered an inadvertent dural puncture. Neuro-imaging revealed features consistent with PRES. The patient went on to make a good recovery, being discharged 21 days postoperatively, with only minor visual disturbances and memory problems. This case highlights the importance of awareness of PRES to all specialties. On reviewing the literature, we feel that PRES may be a potential differential diagnosis to post-procedural neurological symptoms in those patients undergoing routine procedures such as spinal anesthetics or lumbar punctures.

Tension-free vaginal tape (TVT), is a commonly performed, low risk procedure for treatment of stress urinary incontinence (SUI). Severe complications are rare, but can be potentially life threatening. We present a case of 66 year old patient who sustained bladder perforation at the time of TVT procedure and subsequently developed sepsis rapidly leading to multi-organ failure and triggering sequence of serious complications. During her inpatient stay she required ITU admission, emergency laparotomy, TVT mesh removal, bowel resection due to ischemic colitis and anticoagulation for pulmonary embolism. Despite of clinical picture of sepsis her microbiology tests were almost consistently negative. This case emphasise importance of awareness and quick recognition of TVT related complications. Patient ultimately survived and recovered thanks to timely and coordinated management by the multidisciplinary team of doctors.

Lactobacillus species is a known commensal of the mouth, gastrointestinal, and genitourinary tract. However, its isolation on blood cultures is often overlooked and attributed to bench contamination. We present a case of a 58-year-old immunocompetent male who initially presented with altered mental status, but developed sepsis from Lactobacillus bacteremia during his hospital course, while on mechanical ventilation. He was found to have ischemic colitis on colonoscopy. His condition improved with antibiotics and supportive management. Using this example of ischemic colitis, we stress that in the right clinical setting, Lactobacillus bacteremia is a harbinger for a serious underlying pathology and should not be ignored.

Emphysematous pyelonephritis is an acute severe necrotizing infection of the renal parenchyma and its surrounding tissues and up to 95% of the patients have diabetes. We describe a concurrent manifestation of emphysematous pyelonephritis and ischaemic colitis in a 51-year-old diabetic woman and conclude that the colitis was due to pressure from a large retroperitoneal mass and sepsis complications combined with underlying peripheral vascular disease because of diabetes mellitus and hypertension.

Conservative management of an aortic graft infection is defined as "the nonresectional treatment of an aortic graft that has an established infection." Incidence of aortic graft infections is 0.5 to 5% and the estimated mortality rate from aortic graft infections ranges from 8 to 27%. We present the case of a 73-year-old male patient with an infected abdominal aortic graft following an emergency ruptured abdominal aortic aneurysm repair. Postemergency repair, he developed ischemic colitis with sigmoid colon perforation leading to fecal peritonitis and secondary sepsis. He developed a large infective collection within the aortic sac growing vancomycin-resistant enterococcus sensitive to linezolid. A percutaneous drain was placed in the aortic sac and this was irrigated with linezolid for a total of 28 days. The patient clinically improved. Overall, 7 months later, follow-up scan shows complete resolution of infection and the patient remains clinically stable. Conventional treatment of aortic graft infections involves an extra-anatomical bypass. Percutaneous drainage and antibiotic use may be used as bridging therapy for surgery or as definitive therapy when surgical treatment is impractical. Most aortic graft infections grow gram-positive cocci, the organisms form a biofilm which is protected from the external environment. Percutaneous drainage and antibiotic irrigation could possibly penetrate the biofilm and eradicate infection. Morris et al conducted a study on 10 patients having irrigation therapy and systemic antibiotic treatment and found a 1-year survival rate of 80%. In conclusion, conservative aortic graft treatment may be an effective alternative where surgical intervention is not suitable.

We would like to present the case of a 76-year-old female patient with cecal necrosis, which is a rare cause of acute abdomen in elderly women and a variant of ischemic colitis. The patient was admitted to our hospital with abdominal pain, anorexia, and nausea. Physical examination, laboratory parameters, and abdominal computed tomography revealed acute abdomen. We operated the patient with an infra-umbilical midline incision. Considering the pain localized to the right lower quadrant, our initial diagnosis was acute appendicitis; however, we kept in mind other differential diagnoses as well. After laparotomy Non-occlusive cecal necrosis was detected. Arterial pulse was palpated; however, no signs of trombus were detected. Patient also have a Meckel's diverticulum. Terminal ileum plus cecum resection and Meckel's diverticulum excision were performed. Isolated necrosis of the cecum may be caused due to multiple reasons. Especially in elderly female patients with predisposing factors like hypotension, sepsis, shock, drug use, vasculitis, and hypercoagulability, cecal necrosis should be kept in mind.
