A 15-yr-old girl had a life-threatening episode of toxic megacolon at age 6 yr and a life-long history of constipation and abdominal distention. A diagnosis of chronic intestinal pseudoobstruction was made. Her clinical course was that of repeated bouts of pseudoobstruction, multiple episodes of intestinal volvulus at different sites, and progressive cachexia. Histologic examination of specimens of jejunum, ileum, appendix, and colon revealed progressive fibrotic changes in intestinal smooth muscle. The abnormalities observed are most consistent with those described in progressive systemic sclerosis, but no cutaneous manifestations of this disorder have been noted in this child, and no abnormalities in other organs have been detected. Thus, this patient represents a childhood case of chronic intestinal pseudoobstruction caused by a disorder closely resembling progressive systemic sclerosis confined to the gastrointestinal tract.

In a 12-month prospective study incorporating four neighbouring district general hospitals, 228 patients required a total of 236 admissions with intestinal obstruction. The aetiological factors included adhesions 75 (32 per cent), malignant disease 61 (26 per cent), strangulated hernias 59 (25 per cent), volvulus 10 (4 per cent), acquired megacolon 6 (3 per cent), pseudo-obstruction 4 (2 per cent), faecal impaction 6 (3 per cent) and miscellaneous 15 (6 per cent). The peak incidence for obstruction due to adhesions, malignant disease and strangulated hernias each occurred in the eighth decade. Surgery was performed within 48 h of admission in 29 per cent adhesive obstructions (22), 30 per cent obstructions due to malignant disease (18) and 68 per cent strangulated hernias (40)--bowel resection rates in these three groups were 13.5, 50 and 29 per cent, respectively. The overall mortality was 11.4 per cent (26 deaths) and postoperative mortality was 12.3 per cent (19 deaths). During the 12-month study period, 228 patients required a total of 2993 inpatient hospital days as a result of intestinal obstruction. Postoperative adhesions have become the commonest cause of intestinal obstruction but strangulated hernias and intra-abdominal malignant disease still account for 50 per cent of all cases and mortalities. Obstruction due to strangulated hernias and intra-abdominal malignant disease typically occurs in the elderly age group where a more aggressive policy of elective surgical intervention is likely to be associated with increased postoperative morbidity and mortality.

Scleroderma of the colon is commonly associated with constipation, as was the case in a 70-year-old woman with rectal prolapse described by the authors. The chronic constipation in this patient may have been the cause of her rectal prolapse, but the onset of the prolapse and scleroderma at about the same time suggest that the scleroderma may have been a causative factor. A Ripstein repair of the prolapse was carried out. The authors discuss some of the complications of colonic scleroderma, which include megacolon, transverse and sigmoid colonic volvulus, telangiectasia, stenosis and diverticula and stercoral ulceration.

The indications for colonoscopy in a recent consecutive series of 232 examinations were analyzed. Of these examinations, 30 (13%) were performed for nontoxic megacolon. Nontoxic megacolon is defined as severe dilatation of a segment or the entire colon unaccompanied by signs or symptoms of colon toxicity. Mechanical factors (volvulus, anastomosis, diverticulosis, carcinoma) were responsible for the nontoxic megacolon in 13 of these patients. Nontoxic megacolon was classified as secondary to acute pseudoobstruction (Ogilvie's syndrome, pancolonic megacolon, acute myxedema ileus) in 17 patients. All patients were being evaluated for possible exploratory celiotomy to prevent perforation of the colon because of the massive colonic distention. Colonoscopic examination was performed at the bedside or in the intensive care unit for 11 of 30 patients. No bowel preparation was used. Evacuation of air and fecal material was more efficiently accomplished by use of an external suction device attached to the biopsy part of the endoscope. For 12 of the 13 patients who had a mechanical basis for their nontoxic megacolon the colon was successfully decompressed. All 17 patients with acute pseudoobstruction were successfully treated. There were no iatrogenic perforations. Possible emergency operation was avoided for all patients except one who had a cecal volvulus. Colonoscopy should be considered as the initial treatment for nontoxic megacolon prior to surgical intervention.

Sixty-six consecutive patients, admitted to St. Vincent's Hospital, Melbourne, with sigmoid volvulus, fell into two groups, 60 without and six with acquired megacolon. In the former group, flatus tube decompression was usually successful, and sigmoid resection provided a cure. In the group with megacolon, the history was longer; patients more often had bowel symptoms before or between acute episodes of volvulus; flatus tube decompression was rarely successful; and symptoms persisted after sigmoidectomy and were sometimes associated with recurrence of volvulus of the new "sigmoid." It seems that nothing less than total colectomy will cure these patients.

Most bodily functions require the coordinated actions of complementary and supplementary paired muscle groups. Where this essential muscular cooperation is lacking, hollow organs may burst and others become literally screwed up, giving rise to many similar spastic diseases such as Torticollis, Twisted ovarian cyst, Torsion of the Testis, Volvulus of the intestines, Varicose Veins, Megacolon, Aortamegaly, Scoliosis, Erb's Palsy, Peyronie's Disease, Main-en-Griffe, Undescended Foot (Pes Cavus), Talipes, Strabismus. Spasm is "panenepidemic" and unclassified examples of Torsion Dystonia and Dyskinesia really are as common as debt and taxes.

Abdominal rectosigmoidectomy with end to side colorectal mechanical anastomosis is proposed as a new technique for surgical treatment of Chagasic megacolon. The rectum is sectioned and closed at the level of the peritoneal reflexion. The end of the descending colon is anastomosed to the posterior surface of the rectum, as distal as possible, using the intraluminal stapler (Ethicon CDH33). The final result of the operation is similar to Duhamel-Haddad technique with the advantage of being a one stage operation. Forty-three patients with chagasic megacolon were operated on during the period 1989-1994. Twenty-seven were female and 16 were male with ages ranging from 23 to 76 and a mean of 46.1 years. Results obtained were satisfactory; there were no deaths; only three postoperative complications occurred (6.9%). Only one of these (dehiscence of the rectal cupula) was specific for the proposed technique. The two others were intestinal obstruction, due to volvulus of the small intestine in one case and to adhesions in the other. All complications were managed by surgery. All patients are being followed regularly and up to the present time they report daily bowel movements, passing well-formed stools. There are no complaints of fecal incontinence sexual function or disturbed formation of fecaloma in the rectal stump. The colorectal anastomosis was ample in all patients. Since this is a one stage operation with a low rate of complications, the short hospital stay largely compensates the cost of the mechanical suturing device. Regarding recurrences, a long follow-up period of at least 10 years is necessary to evaluate the real effectiveness of this technique.

In a retrospective study of hospital records over a 50-year period, data on 32 patients who died as a result of intestinal obstruction are presented and compared with comparison groups and national mortality statistics. There was a higher incidence and lower mean age at death of fatal intestinal obstruction compared with the total national population. The mean age at death significantly increased over the study period. Intestinal volvulus was a common cause of obstruction particularly in those with cerebral palsy. There was a high prevalence of chronic constipation and megacolon. Foreign-body obstruction was de facto related to pica, but overall, there was a low prevalence of pica. Overall, mean IQ was low, but only significantly so in the male subjects. The length of acute illness was short; in 22 patients it was less than 24 h. Vomiting and abdominal distension were often absent and abdominal signs were recorded only in five patients. Pain or distress was recorded in only nine patients. Only eight patients were correctly diagnosed before death and only two had surgery. The results suggest that fatal intestinal obstruction is more common in mentally handicapped people and chronic constipation and megacolon are risk factors. Intestinal obstruction in mentally handicapped people can present late and with deceptively minimal signs and symptoms.

This article reviews a variety of specific colonic disorders that may have been an acute clinical presentation. Less common causes of colonic obstruction include volvulus, intussusception, and hernias. Nonobstructive colonic dilatation is most often due to pseudo-obstructions and toxic megacolon. Several miscellaneous disorders discussed include colonic perforation, complications of leukemia that may affect the colon, and pseudomembranous colitis. The pathogenesis and clinical aspects of these disorders are reviewed, but the radiologic features are emphasized.

Little attention has been focused on the recurrence rate of sigmoid volvulus after surgical therapy. Consequently, we reviewed the longterm post-operative course of 29 patients who underwent surgery for sigmoid volvulus. The overall recurrence rate was 36 per cent, with recurrences occurring in 7 of 19 patients who underwent sigmoid colectomy and anastomosis; 1 of 5 patients undergoing sigmoid colectomy and end colostomy; and 2 of 4 patients undergoing laparotomy without resection. Although the recurrence rate varied slightly according to the operative procedure performed, the major variable was the degree of colonic involvement, since patients whose disease was limited to the sigmoid colon had a 6 per cent recurrence rate compared to 82 per cent for those with associated megacolon (p = .005). In patients with megacolon treated by subtotal colectomy, no recurrences were documented. Therefore, subtotal colectomy should be considered as the surgical procedure of choice in patients with sigmoid volvulus with associated megacolon.
