Sixty-six patients requiring catheterization in the course of general surgical operations were randomly allocated into two groups. Of the 34 patients catheterized urethrally 16 developed urinary tract infections whereas of the 32 suprapubically catheterized patients only 2 developed an infection (P less than 0.001). Five patients required recatheterization after removal of their urethral catheters. There were no major complications associated with the use of suprapubic catheters. We propose that, when catheterization is required during a general surgical procedure, the suprapubic route is to be preferred.
The syndrome of acute colonic pseudo-obstruction is well delineated but its aetiology remains poorly understood and patients are still treated inappropriately. This article reviews the pathogenesis and surgical management of this condition. Early diagnosis is stressed as a pivotal factor in reducing morbidity and mortality.
A prospective study was made of 92 patients who underwent emergency colorectal surgery during a 1-year period. A dedicated emergency theatre allowed half of the patients to be operated on between 09.00 and 17.00 hours with greater seniority of operating surgeons. The overall mortality rate was 14 per cent and the primary resection rate was 79 per cent. The mortality rate was 12 per cent for right-sided resection with anastomosis and 24 per cent for left-sided resection without anastomosis, including those undergoing Hartmann's procedure which had a 35 per cent mortality rate. Immediate left-sided anastomosis was performed safely in all 14 patients in whom it was attempted. Firms headed by consultants with and without a special interest in colorectal disease made differing use of primary resection and immediate anastomosis (67 versus 41 per cent, P less than 0.05) and Hartmann's (7 versus 25 per cent, P less than 0.05) and non-resectional (15 versus 29 per cent, P not significant) procedures. Retrospective surveys of perioperative deaths examine inadequate management and subsequent mortality rates, but do not reveal the significant morbidity rate that occurs in survivors. This audit revealed significant differences in the management of patients with colorectal emergencies between firms headed by specialist and non-specialist consultants. In order to minimize these differences we believe that recent advances in colorectal practice should be included in the training of all surgeons.
Ninety-three patients who underwent surgery were studied retrospectively over a five-year period for complications of diverticular disease, including free perforation in 32 patients (with fecal peritonitis in 8), inflammation or peritonitis in 22 patients, an abscess in 11 patients, and intestinal obstruction in 14 patients. Sixty-eight patients (73 percent) had systemic symptoms and signs consistent with serious sepsis. There has been a growing popularity of the Hartmann procedure throughout the study period. The overall 30-day mortality rate was 10.8 percent. Because of a high proportion of poor-risk patients, the Hartmann group fared particularly badly compared with those who had other operations, with a 28 percent mortality rate, 69 percent incidence of major complications, and one third of the survivors having a permanent colostomy. Other operative procedures are discussed, but until prospective data become available, it is unlikely that the widespread popularity of the Hartmann procedure will decline. Therefore, the importance of meticulous attention to technical detail is stressed if results are to improve.
One hundred and fifteen patients who were treated by a proctocolectomy in Oxford between 1972 and 1984 for inflammatory bowel disease have been studied. All the patients had the rectum removed by the technique of perimuscular dissection which was introduced in 1972 in an attempt to overcome the problems associated with the previous types of proctectomy. The method has been shown to be safe; the operative mortality was 1.7 per cent. The most worrying potential complications due to permanent autonomic nerve damage (i.e. impotence and urinary incontinence), which previously have been recorded as occurring in a significant percentage of patients, were completely prevented by the method of dissection. One man suffered transient impotence which responded to psychiatric treatment. There were no long term urinary tract or sexual problems. Postoperative complications occurred in 37 per cent of patients, perineal wound infections being the most common (25.7 per cent). Perineal healing, however, was achieved in 75 per cent of patients by the time of their discharge from hospital. The mean length of postoperative hospital stay was 19 days in patients with ulcerative colitis and 15 days in patients with Crohn's disease. Our rate of perineal healing is better than has been recorded using other operative techniques.
Endoscopic transanal resection (ETAR) of rectal tumours is a simple and inexpensive procedure, well tolerated in elderly patients or those undergoing palliation. We have performed 137 ETARs in 81 patients with a 30-day mortality rate of 11.1 per cent and a postoperative complication rate of 15.3 per cent. Thirty-one patients (38 per cent) had ETAR for palliation: in this group rectal bleeding was abolished or improved in 66 per cent of patients, altered bowel habit (diarrhoea) corrected in 77 per cent of patients, faecal incontinence improved in 50 per cent of patients and rectal pain (including tenesmus) improved in 50 per cent of patients. Twenty-three patients (28 per cent) were treated for large benign rectal polyps: in this group symptoms were universally abolished. The technique is particularly suited to the management of these patients. Twenty-seven elderly patients with theoretically 'curable' rectal cancer underwent ETAR with a 78 per cent crude survival rate at 1 year. While long-term results remain to be assessed, ETAR appears a useful technique for treating selected patients with rectal tumours.
Metastatic carcinoma that involves the spleen is usually a manifestation of widely disseminated disease involving multiple organs'. There are only four other cases of solitary splenic metastasis in the British literature2,3.
