The prophylactic value of gentamicin combined with either lincomycin or metronidazole in 52 patients undergoing colorectal surgery was investigated. The results confirmed the value of this practice. In a control group, the sepsis-rate was 48% with 1 death attributable to sepsis, compared with a sepsis-rate of 4% in the treated group. The combination of gentamicin and lincomycin was effective against sepsis but pseudomembranous colitis developed in 2 of the 14 patients treated with this combination of drugs. Lincomycin was discontinued, and when metronidazole was substituted the results were equally good and there were no toxic side-effects.

In a prospective randomised trial in which 93 patients undergoing elective colorectal operations were given a short prophylactic course of metronidazole and kanamycin orally or systemically, postoperative sepsis occurred in only 3 (6.5%) of those given antimicrobials systemically, compared with 17 (36%) of those given oral prophylaxis (P less than 0.01). 15 of the 17 infections in patients who received antimicrobials orally were due to kanamycin-resistant bacteria present in the colon at operation. Bacterial overgrowth of Staphylococcus aureus was recorded in 6 of the patients who received oral therapy. Antibiotic-associated pseudomembranous colitis occurred in 7 patients, 6 of whom had received prophylaxis orally. These results indicate that oral administration of prophylactic antimicrobials in colon surgery should be avoided because of the risks of bacterial resistance, superinfection, and antibiotic-associated pseudomembranous colitis. Systemic per-operative antimicrobial prophylaxis is safer and more effective.

Necrotizing lesions of the colon occur in patients with malignancy. We identified 26 patients with cancer (23 with acute leukemia and three with solid tumors) who died from necrotizing colitis. Autopsies revealed three pathologic categories: pseudomembranous colitis in 69 per cent, agranulocytic colitis in 19 per cent and ischemic colitis in 12 per cent. Most died from sepsis. A comparison of characteristics was made with a control population matched for diagnosis, age, cause of death and duration of neoplasia. Nearly all patients in both groups had fever and were granulocytopenic secondary to chemotherapy. Most received antineoplastic and antimicrobial regimens during the month prior to their terminal illness. Abdominal pain and distention, stomatitis and necrotizing pharyngitis were frequently associated with colitis. Hyperbilirubinemia was a frequent late complication in those with colitis and the control group. Single and multiorganism septicemia were found more frequently in patients with colitis. As antemortem diagnosis was unusual, aggressive attempts at diagnosis are necessary to assess the true incidence of this disorder and the best therapy.

Twenty-eight patients with histologically proved pseudomembranous colitis have been seen in one hospital since July 1975. All patients with the disease had received antibiotics, six for infections not requiring operations; the other 22 cases all occurred after major surgery. All the patients had diarrhoea; six patients also had fever with clinical signs of sepsis, and three had abdominal pain thought to be due to anastomotic dehiscence after colonic resection. Pseudomembranous colitis was associated with white blood counts over 15 000/mm3 in 17 patients and albumin concentrations of less than 30 g/1 in 18. Pseudomembranous colitis was an incidental finding at necropsy in two of six patients who had not had an operation. Of the 22 patients who had had major surgery, nine died from this complication; in all except two of these cases the diagnosis was made only at necropsy. If pseudomembranous colitis is suspected on clinical grounds or if there is an unexplained complication after colorectal surgery repeat sigmoidoscopy and testing for faecal toxins should be carried out to establish the diagnosis so that prompt supportive treatment can be given.

Sixty-two patients were admitted to a prospective randomized controlled trial to investigate the influence of a prophylactic antibiotic, lincomycin, on anaerobic sepsis following bowel surgery. The incidence of postoperative sepsis was reduced from 45 to 18 per cent (P less than 0-025). Wound infections were reduced from 38 to 12 percent (P less than 0-05). Intra-abdominal or pelvic abscess occurred in 1 of the treated group compared with 3 controls. Septicaemia occurred after operation in 1 patient receiving lincomycin and in 3 of the controls; in 2 of the latter, pure growths of bacteroides were isolated from the blood cultures and 1 of these patients died. Although lincomycin had no influence on the number of patients who developed aerobic postoperative infections, there was a significant reduction in the incidence of sepsis due to bacteroides, which occurred in 10 of the control group compared with 1 in the lincomycin group (P less than 0-005). No patients developed complications attributable to lincomycin, such as pseudomembranous colitis. These data indicate that the genus Bacteroides are important pathogenic organisms and are responsible for postoperative morbidity. Furthermore, anaerobic sepsis can be reduced by appropriate prophylactic antibiotics.

This is the first reported case of cephazolin-associated pseudomembranous colitis. The disease followed a relentless course from its onset to twelve days later when the patient underwent total colectomy for multiple perforations and then died of sepsis. Recent reports indicate that the incidence pseudomembranous colitis is higher than initially appreciated. Early recognition of this entity with confirmation by proctosigmoidoscopy and immediate discontinuance of of antibiotic therapy may reduce the morbidity and mortality of this disease.

Hospitalized patients who received clindamycin or ampicillin were evaluated for gastrointestinal side effects for a period of up to six weeks after therapy was discontinued. Of 104 patients receiving clindamycin therapy, 31 (29.8%) developed diarrhea, and two (1.9%) developed pseudomembranous colitis (PMC). Of 138 patients receiving ampicillin, 24 (17.3%) developed diarrhea, and one (0.7%) developed PMC. Diarrhea persisting for three days or more was noted in 13 (12.5%) of the patients receiving clindamycin and in seven (5.1%) of those receiving ampicillin. The tendency to develop diarrhea was positively correlated with serious illness, abdominal or pelvic sepsis, and total dosage of clindamycin. Examination of stools from a patient with PMC that was associated with clindamycin therapy showed a decrease in the number of anaerobic bacteria from the numbers found in stool cultures of normal controls. Those patients who did not develop diarrhea also had fewer anaerobic bacteria and coliform organisms. Lymphocytes from the patient with PMC were hyporeactive to phytohemagglutinin and hyperreactive to clindamycin.

The clinical and histologic changes occurring with antibiotic-associated pseudomembranous colitis are usually reversible with discontinuation of the causative medication. The spectrum of disease patterns ranges from a benign form to a very fulminant and occasionally fatal one. This report describes a child with a severe form of the disease. Despite recognition and sigmoidoscopic confirmation of this syndrome and cessation of antibiotics, his course continued to deteriorate. Sepsis, leukocytosis, refractory diarrhea, and abdominal distension led to exploratory laparotomy. A proctocolectomy was performed for necrosis of the entire colon; however, the patient died of sepsis.

The presentation of pseudomembranous colitis ranges from mild self-limiting diarrhea to fulminant colitis with overwhelming sepsis. The management of the severe forms of this disease, including the role of surgical intervention, is poorly defined. To evaluate the management and outcome in severe cases, the authors reviewed the records of six patients (four women, two men) seen at The Toronto Hospital between 1985 and 1989 with pseudomembranous colitis manifesting as fulminant colitis. The patients ranged in age from 19 to 69 years (mean 52 years). All presented with nonbloody diarrhea, had peritoneal signs and were severely dehydrated, and all had received antibiotics between 4 days and 6 weeks before the onset of symptoms. The mean preoperative leukocyte count was 40.9 x 10(9)/L. Radiologically, the colon appeared to be dilated in three patients. Two patients were operated on immediately. The other four were treated medically, but three of them required surgery within 24 hours of presentation. Four (67%) of the six patients died. All four had been treated surgically. The mean age of the survivors was 28 years compared with 64 years for those who died. Pseudomembranous colitis can present as severe acute colitis and can carry a high mortality, especially in the aged. Surgical treatment may be required in those who fail to respond to medical management or have peritoneal signs.

Surgical intervention after vascular surgery usually occurs as a result of bleeding or thrombosis, whereas general surgical problems requiring operation after vascular surgery are unusual. The purpose of this study was to review the results of operations for general surgical problems done soon after major vascular surgery. From January 1985 to December 1989, 1,236 major vascular procedures were performed, and 15 patients developed significant postoperative general surgical problems including perforated duodenal ulcer (2), perforated diverticular disease (2), evisceration and dehiscence (2), liver infarct (1), gangrenous cholecystitis (2), clostridial myonecrosis (1), pseudomembranous colitis (1), and small bowel obstruction (4). The overall mortality was very high (47%), and the chance of dying was significantly higher (p less than 0.05) if the initial vascular procedure was an emergency (100% mortality). All the patients who died (n = 7) succumbed to sepsis. There was a long delay in diagnosis in all groups; however, the delay did not correlate with mortality. Although this is a study of a small group of patients with a very heterogenous group of complications, several observations can be made: (1) a general surgical problem after vascular surgery carries a very high mortality; (2) general surgical complications in postoperative vascular patients in whom the initial procedure was an emergency are very poorly tolerated and almost uniformly lethal; and (3) these elderly patients have multiple medical problems and seem unlikely to tolerate any septic insult.
