The presence of HPVG has been said to constitute a mandatory indication for exploratory laparotomy, given the high incidence of concomitant bowel necrosis and abdominal sepsis. HPVG has also been associated with increased intraluminal pressure in the absence of bowel ischemia. Most cases are iatrogenic, usually due to barium enema or colonoscopy in patients with inflammatory bowel disease, but in a few cases, HPVG is associated with simple intestinal or gastric distention. The English literature on the subject describes only eight such cases. We recently treated a patient in whom HPVG was caused by intestinal pseudo-obstruction. Such an etiologic mechanism has not been previously reported. The relevance of this observation and a reassessment of the absolute obligation to operate prompted this review.

Impaired mental status is a poorly understood manifestation of sepsis and may be associated with altered permeability of the blood-brain barrier. To examine the possibility that sepsis affects permeability of the blood-brain barrier, rats were infected with a peritoneal implant consisting of sterilized feces, barium sulfate, and 10(8) colony forming units (CFU) of Escherichia coli. Using this model, reproducible episodes of peritonitis with bacteremia resulted. Rats were sacrificed hourly after 5 min circulation of 100 mg horseradish peroxidase. Animals were perfused-fixed and the brains removed. Representative coronal sections were stained for peroxidase reaction product and cerebral blood vessels were examined microscopically for evidence of HRP staining and extravasation. The number of stained cerebral vessels from infected rats was increased at all times compared to uninfected control rats. Extravasation of horseradish peroxide within neuropil was significantly higher in hours 1, 4 and 5 as compared to controls. The lack of significant increase in hours 2 and 3 may suggest transient closing or repair of the tight junctions. We conclude that peritonitis and bacteremia are associated with increased permeability of the blood-brain barrier.

A 64-year-old man with Crohn's disease who had undergone repair of an ileovesical fistula and ileoileostomy had numerous postoperative complications related to sepsis and wound healing. Subsequently, upper gastrointestinal bleeding developed, and the site was identified as a duodenal sinus. Medical management was unsuccessful in controlling the bleeding. Because of the considerable risk associated with reoperation in this seriously ill patient, approval was obtained from the Food and Drug Administration to use fibrin glue in an attempt to prevent further bleeding. The glue was mixed with barium and placed in the duodenal sinus under endoscopic guidance. The barium-impregnated glue facilitated follow-up surveillance with abdominal roentgenography. The patient had no further gastrointestinal bleeding. Further clinical and experimental studies should be conducted to determine the mechanism of action and the efficacy of this application of fibrin glue.

Immunodepression associated with a variety of situations such as cancer or any of its major modalities of treatment (surgery, irradiation, or chemotherapy) has been effectively alleviated with Imunovir (inosine pranobex-BAN), and this has been associated with demonstrable clinical benefit to these patients. One hundred and six immunodepressed patients with solid tumors undergoing radiotherapy were treated with either Imunovir or placebo; 64% of Imunovir-treated patients were immunorestored after 3 months compared to 23% in the placebo group. Imunovir was also effectively used in 75 patients with malignant hematological disorders both as an immunorestorative agent given prophylactically to prevent infection and as a therapeutic agent to treat infections in these immunodepressed patients. In different studies involving surgical patients treated with either Imunovir or placebo, 70-81% of hypoergic or anergic patients in the Imunovir group became normoergic by day 14 of treatment compared to 5-17% of the placebo group, and this enhanced immunorestoration was associated with lower incidence of local sepsis (P less than 0.05), systemic sepsis (P less than 0.025), and postoperative mortality (P less than 0.05).

The pathogenicity of enterococci in intraabdominal sepsis has not been clarified. Therefore, fecal-type peritonitis was induced in rats by intraperitoneal injection of barium sulfate along with a bacterial inoculum consisting of Escherichia coli, Bacteroides fragilis, and Clostridium perfringens with or without Streptococcus faecalis. Mortality at 19 d and characteristics of intraabdominal abscesses in survivors at 19 d were analyzed. The presence of S. faecalis in the original inoculum was significantly associated with death or large (greater than 20 mm) abscess formation when these two end points were examined together. S. faecalis may synergize with other bacteria in intraabdominal sepsis to augment morbidity and possibly mortality.

Diverticulitis represents a spectrum of clinical entities ranging from minimal pericolitis in the adjacent mesentery to uncontrolled intra-abdominal sepsis and septic shock. The presentation most often described is left lower quadrant abdominal pain, fever, chills, and left lower quadrant tenderness associated with a mass. Unusual presentations occur when infection tracts to distant locations. Diverticulitis is a common cause of intra-abdominal sepsis associated with high morbidity and mortality. The pathogenesis of intra-abdominal sepsis is not well understood, but likely involves circulating host inflammatory mediators. The role of computed tomography in the early diagnosis of diverticulitis is increasing and supersedes barium enema in the assessment of the extracolonic extent of disease. Also, computed tomographic-directed percutaneous drainage of intra-abdominal abscesses is, in most cases, as effective as surgical drainage. Predictably, the micro-organisms involved are representatives from the commensal flora of the lower gastrointestinal tract. These bacteria are usually sensitive to a wide range of antimicrobial agents that are effective against facultative and obligate anaerobic gram-negative bacilli. Surgical intervention is reserved for those individuals who do not respond to therapy, or for generalized peritonitis, uncontrolled sepsis, free viscus perforation, and fistulas.

Scleromyxedema is a rare fibromucinous connective tissue disorder characterized by papular skin lesions associated with sclerosis and a serum monoclonal gammopathy. Little is known about either the natural history or the systemic manifestations of this disease. We reviewed the medical records of 19 patients with biopsy-proven scleromyxedema seen from 1950 to 1985 for evidence of systemic disease. There were 10 males and 9 females with a median age at diagnosis of 53 years. Monoclonal gammopathy was present in 13 patients. Eight patients complained of dysphagia; 3 had proximal esophageal dysfunction and 1 had total esophageal aperistalsis on barium swallow. Proximal muscle weakness was noted in 5, with an inflammatory myopathy in 3. Six patients complained of dyspnea on exertion. Of these, 5 had reduced diffusing capacity, 3 had reduced volumes, and 2 developed cor pulmonale. Pathologic changes characteristic of "scleroderma kidney" were demonstrated in 1 patient at postmortem. One patient had Raynaud's phenomenon and 2 had arthralgias/arthritis with noninflammatory synovial fluids. Although 8 of 12 patients treated with melphalan noted regression of their skin changes, no consistent improvement in the extracutaneous manifestations was demonstrated. Furthermore, 2 patients died of sepsis related to melphalan-induced myelosuppression, and 4 developed hematological malignancies following melphalan therapy. In conclusion, systemic manifestations in scleromyxedema are more prevalent than previously recognized, and can resemble those of scleroderma. Significant toxicity occurred with the use of alkylating agents in these patients, with treatment-related complications developing in 45% of patients treated with melphalan. The lack of definitive data regarding the natural history of this disease complicates the question of optimal therapy, but the use of alkylating agents should be reserved for those patients with severe debilitating skin disease.

The records of 300 patients with a diagnosis of small bowel obstruction were evaluated to determine which factors, if any, were prognostic of clinical outcome. Ninety per cent of patients had at least one prior abdominal procedure; those of a gynecologic or obstetric nature were most common. Abdominal pain (92%), vomiting (82%), abdominal tenderness (64%), and distention (59%) were the most frequent symptoms and signs, and plain abdominal x-rays were abnormal in 273 (91%) patients. Two hundred and nine patients (70%) underwent surgical repair, of which 48 (23%) required resection of intestine for densely adherent or strangulated bowel. Contrast studies were generally not helpful and associated with barium peritonitis in two patients. The mortality rate for the entire series was 9 per cent, which doubled for those who underwent resection. Septic complications occurred in 31 per cent of the survivors in this group. Fourteen of the 16 patients who died from abdominal sepsis had a delay in presentation and/or treatment, which was the most important prognosis factor for patient outcome.

The experience of 66 cases of colovesical fistula is reported. The most common cause was diverticular disease (71%), the remainder being due to malignancy, Crohn's disease, radiotherapy, appendicitis and trauma. The most sensitive investigation was barium enema, which was abnormal in 98% and actually showed the fistula in 57%. In 32 patients a single stage resection was performed, without mortality or significant morbidity and we would advocate this form of treatment for fistulae which are not complicated by gross sepsis or obstruction.

Intussusception remains a leading cause of bowel obstruction in early infancy and childhood. From 1970 to 1985, 83 patients with intussusception were treated. There were 51 boys and 32 girls ranging in age from 2 months to 22 years. Ten patients had a total of 14 separate recurrences; nine occurred during the initial hospitalization. Symptoms on presentation included abdominal pain (80%), palpable mass (60%), rectal bleeding (53%), and lethargy or sepsis (45%). Fifteen children underwent exploration without contrast studies based on duration of symptoms (greater than 5 days) and evidence of severe obstruction on plain abdominal x-ray films. In the remaining children, diagnosis was confirmed by barium enema and hydrostatic reduction was achieved in only 34 patients (42% success rate). Symptoms were present more than 48 hours in 55% of the reduction failures. At operation, five children had spontaneously reduced and an appendectomy was performed. Manual reduction was possible in 32 patients. The intussusception was irreducible in 26 patients, and 18 required temporary stomas. Pathologic lead points were found in 11 patients. Average length of hospitalization was 1.5 days after barium enema reduction, 9.6 days after manual reduction, and 13.8 days after bowel resection. There were no recurrences of intussusception after surgical reduction. A significant morbidity rate was observed with a delay in diagnosis. Adequate preoperative preparation and prompt surgical intervention are associated with 100% survival.
