From 1985 to March 1991, 83 patients with the diagnosis aortoiliac obliteration and aortic occlusion were operated on at the Department of Surgery, Nordland Central Hospital. The main symptom was claudicatio intermittens. 16 patients had pain while at rest, and two had gangrene. The surgical technique was either Y-prosthesis or thrombendarterectomy. Four patients (4.8%) died postoperatively, three of myocardial infarction and one of intestinal ischemia and peritonitis. In our study 66 patients with aortoiliacal atherosclerosis were compared with 17 patients with aortic occlusion. Patients with aortoiliacal atherosclerosis demonstrated by angiography had much more severe infrainguinal arterial pathology. In the occlusion group the postoperative outcome, as measured by ankle/brachial index, was significantly better (p < 0.01). The study included four female patients less than 50 years of age with total infrarenal aortic occlusion. Their symptoms and signs are discussed.

In an attempt to commit suicide, a 32-year-old women swallowed a vast amount of psychiatric drugs, i.e. tranquilizers, amphetamines, hynotic and antidepressant agents. By intensive care, using high doses of catecholamines and appropriate antidota, satisfactory circulation and oxygenation could be maintained. 3 days after admission a peritonitis became apparent. A 50 cm long section of the distal ileum was found to be completely necrotic and had to be resected. However, circulation of the correspondent mesenterium was not disturbed at all. A drug-induced non-occlusive intestinal ischemia was postulated to be the pathophysiological mechanism of intestinal necrosis. Non-occlusive intestinal ischemia is rare; it has been reported in young adults intoxicated by cocaine or phenobarbital, in children with high overdosage of iron compounds, in elderly individuals suffering from low-output congestive heart disease and in patients treated with digitalis drugs, with or with or without overdosage.

This elderly male with a long history of alcohol abuse presented with an acute pleural trauma and hemopneumothorax, which may have served as the precipitating medical illness for cecal volvulus. He subsequently developed bacterial peritonitis as a complication of his bowel obstruction. It is probable that his pleural cavity was seeded hematogenously via a bacteremia from his peritonitis, thus accounting for the empyema with species typical of bowel flora. Cecal bascule is a type of cecal volvulus that causes intestinal obstruction. Diagnosis is difficult, but a delay in recognition may result in intestinal ischemia, perforation, sepsis, and even death. Cecal ischemia or gangrene cannot always be determined based on physical examination or laboratory findings. Plain films of the abdomen may be helpful, and barium enema has been advocated by some authors. However, laparotomy is often necessary for definitive diagnosis and therapy. While cecal volvulus has not been reported to occur frequently in the elderly, the relatively common occurrence of anatomic predisposition in addition to the widespread use of respirators and the increasing age and number of medical illnesses of our population make it possible that cecal volvulus will be seen with increasing frequency in the future.

Intestinal ischemia after aortic surgery is a rare (1-5%) complication, often with a fatal outcome (greater than 50%). During the period 1974-1987, 554 abdominal aortic operations were performed in our department. 17 patients (3%) were reoperated due to bowel ischemia, ten of these patients died. 12 patients were operated on due to aortic aneurysm (9 emergency operations) and 5 due to occlusive disease. A retrospective analysis of the files of the 17 patients was performed to try to identify the risk patient. Preoperative investigations demonstrated that the inferior mesenteric artery (IMA) was patent in 3 patients and occluded in 5 patients. As to the other 9 patients no information could be found (all with aneurysm). After the primary operation, 11 patients had persistent circulation via at least one of the hypogastric arteries and none of them had persistent circulation via the IMA. 11 patients had bloody diarrhea before reoperation and in 6 patients peritonitis was observed. Rectoscopy was performed in 8 patients and in 7 there was indication of ischemia. The most common finding among the laboratory tests was a rise in the creatinine level which was observed in 10 patients. Other laboratory tests such as blood gases, leucocytes, thrombocytes or temperature were of little predictive value per se. Patients operated on due to ruptured aortic aneurysm are risk patients. No other predictive symptom or sign was found to preoperatively identify the patient at risk for intestinal ischemia. An intraoperative method for evaluating the intestinal blood flow would be of great value when considering selective intestinal vascular reconstruction.

The barium enema is a safe and accurate diagnostic study of the colon but, in rare cases, complications may result. Many of these can be prevented by proper equipment and careful attention to technique. When a complication does occur, prompt recognition and management is vital in decreasing morbidity and mortality. Perforation of the bowel is the most frequent serious complication, occurring in approximately 0.02% to 0.04% of patients. Rarely the colon may burst due to excessive transmural pressure alone. However, a colon weakened by iatrogenic trauma or disease is more likely to perforate during an enema than is a normal healthy bowel. Injury to the rectal mucosa or anal canal due to the enema tip or retention balloon is probably the most common traumatic cause of barium enema perforation. Inflation of a retention balloon within a stricture, neoplasm, inflamed rectum, or colostomy stoma is particularly hazardous. Recent deep biopsy or polypectomy with electrocautery makes the bowel more vulnerable to rupture. The tensile strength of the bowel wall is impaired in elderly patients, patients receiving long-term steroid therapy, and in disease states including neoplasm, diverticulitis, inflammatory bowel disease, and ischemia. Intraperitoneal perforation leads to a severe, acute peritonitis with intravascular volume depletion. The ensuing shock may be rapidly fatal. Prompt fluid replacement and laparotomy are essential. If the patient survives the initial shock and sepsis, later complications caused by dense intraperitoneal adhesions may develop. Extraperitoneal perforation is usually less catastrophic but may result in pain, sepsis, cellulitis, abscess, rectal stricture, or fistula. Intramural extravasation often forms a persistent submucosal barium granuloma which may ulcerate or be mistaken for a neoplasm. The most dramatic complication of barium enema is venous intravasation of barium. Fortunately, this is quite rare as it may be immediately lethal. Most cases have been attributed to trauma from the enema tip or retention balloon, mucosal inflammation, or misplacement of the tip in the vagina. Bacteremia has been found in as many as 23% of patients following barium enema and, in rare cases, may cause symptomatic septicemia. Other less common complications include barium impaction, water intoxication, allergic reactions, and cardiac arrhythmias. Preparatory laxatives and cleansing enemas have been implicated in some instances of dehydration, rectal trauma, water intoxication, and perforation. Careful review of the indications for examination, previous radiographs, and clinical history will identify many of the patients at greater risk for complications so that appropriate precautions may be observed.(ABSTRACT TRUNCATED AT 400 WORDS)

Underlying cellular hypoxia, which may be difficult to detect, has been postulated to be a major cause of morbidity and mortality in sepsis. We employed the novel hypoxic marker [18F]fluoromisonidazole to determine whether cellular hypoxia was present in a peritonitis model of sepsis in the rat. A second group of septic and control rats had organ blood flow measurements determined by the radiolabeled microsphere technique to relate possible ischemia to decreased organ perfusion. No evidence of cellular hypoxia was detected in skeletal muscle, brain, liver, heart, or diaphragm in the septic rats. Ligation of the femoral artery caused a greater reduction in flow (55% decrease vs. 20% decrease, P less than 0.05) and an increased retention of [18F]fluoromisonidazole in skeletal muscle of the septic rats. We conclude that sepsis does not invariably result in systemic, i.e., multiorgan, cellular hypoxia and that underlying cellular hypoxia is not the major pathophysiological abnormality in sepsis. The greater reduction in muscle blood flow and the increased retention of [18F]fluoromisonidazole in the ischemic muscle of septic rats implies that they may be more vulnerable to hypoxia.

Three Holstein cows were admitted on postpartum day 3 with signs of abdominal pain, inappetence, and decreased milk production. All 3 were depressed, tachycardic, and dehydrated. Right paralumbar fossa laparotomy was performed on each cow. At surgery, a rent in the proximal portion of the jejunal mesentery, with perforation of the jejunum adjacent to the mesenteric rent, was found in all 3 cows. All had evidence of severe peritonitis and gross contamination of the abdomen with digesta. Because of severe peritonitis and inability to exteriorize the affected segment of jejunum, all 3 cows were euthanatized. We postulate that the mesenteric rent occurred at the time of parturition, resulting in ischemia and jejunal perforation in the segment of jejunum adjacent to the rent.

A phase I study to evaluate the use of i.p. infusion of recombinant interleukin-2 (rIL-2) was planned. The following dose levels were calculated: 0.1, 0.3, 1.0, 3.0 and 10 mg/m2/day for 14 days, but only the second levels were reached. In this trial the acute toxic effects at this dosage included cardiac ischemia, transient liver impairment and septic peritonitis. The maximum tolerated dose (MTD) was 0.3 mg/m2/day for 14 days. In addition, two patients developed peritoneal fibrosis. No objective responses were observed. Therefore, in order to explore the biological activity of low (nontoxic) doses, three patients (one untreated and two previously treated with rIL-2) were infused with 0.01 and 0.03 mg/m2/day for 7 days. Potentiation of cytolytic activities in peritoneal lymphocytes and activation of a lymphokine cascade in the ascitic fluid were observed at doses ranging from 0.03 mg/m2/day to 0.3 mg/m2/day. These findings in association with the toxic effects observed at the MTD suggest the use of the minimum effective dose for future locoregional immunotherapeutic protocols.

Episodes of catastrophic entero-colitis associated with mesenteric vascular insufficiency in patients with rheumatoid arthritis(RA) have rarely been recorded thus far. We herein report two cases of RA complicated with severe attacks of entero-colitis presumably due to mesenteric vasculitis. Surgical intervention was necessary in the first case, while the second patient recovered well only through conservative therapy. Case 1: A 74-year-old man with history of RA since 1985 started to complain of abdominal discomfort and nausea early in February, 1989. On February 12, Episodes of tarry stool developed. Rapid down-hill clinical course prompted laparotomy under the clinical diagnosis of peritonitis. Ischemic changes were observed at the ileum end, the entire length of which was 120 cm orally from the cecum. The site was resected. Multiple linear and aphthoid ulcer lesions were discovered throughout the entire lumen. Histopathologically, evidence of necrotizing vasculitis such as fibrinoid necrosis and mural thrombi was demonstrated in small arteries of the submucosal layer underlying the ulcer lesion. Case 2: A 63-year-old woman who had been suffering from RA since 1980 noticed the onset of nausea, abdominal pain and bloody diarrhea in July, 1989. Colonoscopy examination revealed multiple linear and aphthoid ulcers in the sigmoid colon which was presumed to be due to ischemia. Laboratory evaluation at that time demonstrated hypocomplementemia, positive circulating immune complex and high titer of anti-DNA antibody. Corticosteroid therapy with moderate dose was successful in alleviation of all the abnormal findings and the patient fully recovered three months after her initial GI episode.

Pelvic pain is often a difficult differential diagnosis in the emergency department. For physiologic reasons, pain in the pelvis is difficult to localize to a specific organ, and pelvic peritonitis is hard to recognize. On the other hand, differences in types of pain can be very useful in arriving at a correct diagnosis. The clinician must learn to recognize superficial and deep somatic pain, and differentiate between various types of visceral pain which originate from inflammation, ischemia, or colic. A review of the anatomy and physiology of pelvic pain helps identify some of the problems as well as potential aids in approaching the patient with pelvic pain.
