[Incidence and management of surgical pathology in children with cystic fibrosis of the pancreas].

This report reviews 110 children of ages ranging from 2 months to 17 years, with a diagnosis of cystic fibrosis, and analyzes the surgical treatments they have undergone. In our series, meconium ileus shows an higher occurrence (20%) than the reported by the literature. No direct relationship could be established between the existence of meconium ileus and a more severe affectation of cystic fibrosis. Rectal prolapse occurred in 10% of the patients, and only 4% underwent surgical treatment. Three children with appendicitis developed a periappendiceal abscess due to delayed diagnosis and 2 other were operated upon for meconium ileus equivalent. From 7 patients with gastroesophageal reflux, 5 were treated non-operatively and 2 required corrective surgery. Fifty five patients out of the 110 (45%) underwent different surgical procedures.

A field outbreak of chronic aflatoxicosis in dairy calves in the western Cape Province.

An outbreak of mortality in Friesland dairy calves in which 7 out of 25 calves died in the western Cape Province, Republic of South Africa is described. Clinical signs included a loss in body mass, staring hair coat, diarrhoea and rectal prolapse. Histopathological changes in the liver were characterised by severe portal fibrosis with bile duct proliferation and mild portal round cell infiltration. The calves were fed a ration containing locally-produced maize. The implicated maize was infested with Aspergillus flavus and contained aflatoxins B1, B2, G1 and G2 with total aflatoxin levels as high as 11,790 ng g-1. This is the first report of a field outbreak of bovine aflatoxicosis in South Africa.

Treatment of proliferative colitis in ferrets.

Proliferative colitis associated with intracellular Campylobacter sp was diagnosed in 10 ferrets. The ferrets had a history of diarrhea (often blood-tinged or mucoid), dehydration, and chronic weight loss. Additional clinical signs included rectal prolapse, lethargy, fever, and a palpably thick colon. In 5 ferrets, the diagnosis was confirmed by colonic biopsy, via endoscopy. Supportive treatment in 5 ferrets did not alleviate the clinical signs or the proliferative intestinal disorder. oral chloramphenicol treatment (50 mg/kg of body weight, q 12 h for 10 to 21 days) resulted in marked clinical improvement and eradication of proliferative intestinal lesions in 5 ferrets.

Urologic syndrome associated with wire caging in AKR mice.

Individually housed male AKR/NCrlBR mice used in a chronic inhalation experiment were noted to develop a severe obstructive genitourinary condition. The mouse urologic syndrome (MUS) had one or more of the following features: bladder distension; peripreputial urine staining, alopecia, and edema; paraphimosis; urethral blockage; ulcerative balanophosthitis; hydronephrosis; pyelonephritis; rectal prolapse; and perineal ulcerative dermatitis. MUS was less severe and less prevalent in similarly housed B6C3F1/CrlBR and NIH-Swiss mice used in the same experiment. Epidemiologic evidence within the animal facility restricted the syndrome to the inhalation toxicology area. The effects of intermittent water deprivation as well as wire caging on the development of MUS were studied because these conditions were only utilized in the inhalation facility. Male AKR/NCrlBR mice, caged individually in suspended wire caging or kept isolated in polystyrene shoebox style cages containing wire floorwalk bottoms, all developed MUS within 16 weeks. Mice which were housed directly on hardwood bedding in identical plastic caging remained free of the syndrome, as did castrated males which were kept in suspended wire cages. Water deprivation was not found to be a major contributing factor to the development of the condition, but was found to augment its severity. We concluded that although MUS is probably multifactorial in etiology, housing susceptible animals on wire bottom caging may exacerbate the incidence and severity of the condition in certain strains of male mice.

Small colon intussusception in a broodmare.

A 9-year-old pregnant Standardbred broodmare was evaluated for signs of mild abdominal pain, failure to defecate, and mild abdominal distention. Rectal examination revealed the leading edge of a small colon intussusception, and peritoneal fluid analysis indicated suppurative peritonitis. Surgical management, including reduction of the intussusception and small colon resection with end-to-end anastomosis, resulted in successful outcome (1-year follow-up evaluation). Postoperative complications including dehiscence of the ventral midline surgical incision and simple obstruction at the anastomosis site necessitated a second surgical procedure. Small colon intussusception is an uncommon cause of signs of abdominal pain and is similar to type-IV rectal prolapse.

Fecal incontinence. Diagnosis and treatment.

This is a survey of fecal incontinence. The etiology is multifactorial. It may develop after traumatic lesion of the anal sphincters, neurological disorders, rectal prolapse or idiopathic. The treatment may be conservative including diet, drugs and sphincter exercise or consisting of suture of the sphincter, post anal repair, free autogenous muscle transplantation. In some cases colostomy is the only way of choice.

A natural outbreak of transmissible murine colonic hyperplasia in A/J mice.

Transmissible murine colonic hyperplasia was diagnosed in 6-month-old A/J mice kept under standard laboratory conditions. Bacterial cultures revealed the presence of Citrobacter freundii (4280). Clinical signs included rough coats, feces adhering to the anus, slight dehydration and rectal prolapses. A nonclotting sanquinous intestinal fluid and gross colonic thickening were frequently seen at necropsy. Morbidity was approximately 50%; mortality approximately 25%. Tetracycline appeared to be effective in controlling the disease.

Cystic fibrosis. As they grow older.

Twenty-eight patients with cystic fibrosis, who survived to over 18 years of age are reported. The ages at the time of diagnosis ranged from and two and half months to over 21 years. Manifestations of cystic fibrosis in adults and youngsters are compared and contrasted. A review of the patients surviving shows that steatorrhea is under control. There is no evidence of biliary cirrhosis in any of these patients. Rectal prolapse has not been an important factor. Pseudomonas and Staphylococci were the major infecting organisms causing lung disease. Two-thirds of the patients do not use prophylactic antibiotics and one-third do not practice regular pulmonary care. Two female patients died; one of Pseudomonas lung infection and respiratory failure, after a pregnancy that was carried to term (live baby); one, of respiratory failure, also with severe Pseudomonas respiratory tract infection, two years after a pregnancy that was terminated in the first trimester.

[Colorectal prolapse in a child with a severe form of juvenile polyposis].

Colon polyps are very common in infancy, most cases are unique, seldom exceeding ten; as a rule, the treatment is endoscopic resection. The AA present a case of a severe diffuse colorectal juvenile polyposis in an 8-year-old black child, with a 4-year evolution of serious digestive bleeding, abdominal pains, anemia and hypoproteinemia. The disease scattered throughout the colon with a great density at the rectum and sigmoid level, coating fully the mucous membrane, making the classic treatment by endoscope unworkable. A resection of the rectum and descendent colon with transrectal pullthrough by the Soave technique with anal demucosization was performed. The post operative without incidents and the follow-up period was considered satisfactory. Complementary endoscopic resection of the remaining and scattered polyps followed. The result of the histopathological examination of all elements studied was juvenile polyps. This case demonstrates the necessity of surgical treatment with resection in cases of severe diffuse juvenile polyposis, in which endoscopic resection alone is not deemed to be sufficient.

Preventable causes of bowel resection in Zaria, Nigeria: a report of 93 cases.

This report presents a summary of 93 bowel resections which were considered to be for preventable causes and performed during 5 years (1984-1988) in our Hospital in Zaria. These resections constituted 57% of the total bowel resections performed in that period and were responsible for an annual resection rate of 19 "avoidable" bowel resections. The resections included 48 for strangulated external groin hernia with gangrene of the bowel or doubtful viability, typhoid perforation eleven, vehicular trauma ten, anastomotic dehiscence eight and other non-neoplastic causes of faecal fistula eight. Multiple special forms of preventable causes of bowel resection accounted for 8 resections. These were foreign body impacted in the ileum 1, incisional hernia 1, large irreducible scrotal hernia in a recently gangrenous scrotum 1, irreducible rectal prolapse 2, paracolostomy abscess 1, bowel necrosis from residual pelvic abscess 1 and from multiple intra-abdominal abscesses one.

Giardiasis in laboratory-housed squirrel monkeys: a retrospective study.

Giardia infection was diagnosed in a 1.5-year-old, group-housed, female squirrel monkey with diarrhea. A retrospective study was undertaken to evaluate the incidence of Giardia in the 190-member colony. Records were analyzed to determine whether any one of the following conditions applied: the animal had clinical signs referable to the gastrointestinal system; a fecal examination for ova and parasites was performed; gastrointestinal parasitism was revealed by necropsy; or a culture of samples from the gastrointestinal tract was performed. Analysis revealed a total of 19 monkeys, 68% (13/19) of which had gastrointestinal clinical signs. Giardia cysts were recovered from 33% (4/12) of monkeys with gastrointestinal signs in which fecal examinations were done. The yearly incidence of diarrhea in the colony was low at 0.61%; however, 33% (2/6) of the monkeys with diarrhea were positive for Giardia. Six animals had blood in the feces or rectal prolapse, in the absence of diarrhea, and 30% (2/6) of these animals were positive for Giardia. Of six animals without gastrointestinal clinical signs, 50% (3/6) had giardiasis, which was listed as an incidental finding. In light of these findings, an additional 16 healthy animals were examined for Giardia. Giardia cysts were recovered from 50% (3/6) of males and 70% (7/10) of females from which samples were obtained. Additionally, clean water consumed by the animals was negative for Giardia cysts, and facility waste water was positive. To our knowledge, this is the first report of giardiasis in squirrel monkeys.

[Intestinal occlusion due to a colonic lipoma. Apropos 2 cases].

Lipomas occur through the intestinal tract, from the hypopharynx to the rectum, the colon having the highest incidence, where lipomata are the commonest benign neoplasm after adenomata. Nevertheless they are uncommon. CASE REPORT. 1) A 68-year-old man presented as an emergency with abdominal pain associated with bowel obstruction. He had a 2 to 3 month history of intermittent right-sided abdominal pain, constipation spontaneously resolved. At laparotomy there was a mass of the transverse colon, next hepatic flexure. A right hemicolectomy was performed. The patient made an uneventful recovery. Histologic examination showed a lipoma of the submucosal plane. 2) A 65-year-old man presented as an emergency with lower abdominal pain associated with a prolapsed rectal polyp. He had 1 month history of passing fresh blood per rectum. Ap ast colonoscopy revealed a large polypoid lesion in the descending colon. Transanal examination revealed a polypoid lesion with a maximum diameter of 4 cm, acting as an intussuseptum. Transanal polypectomy was performed. At laparotomy there was an intussuseptum of the descending colon into the rectum: a left hemicolectomy was performed. Histology showed the polyp to be a submucosal lipoma. DISCUSSION. Lipomas are the most common benign nonepithelial tumors of the colon. Lipomata of the large bowel are reported as incidental findings in 0.3-0.5% of cases in large series of autopsies. In the wall of the intestine most lie in the submucosal plane, less frequently they are found in the subserosal plane. The commonest site for symptomatic solitary large bowel lipoma is the ascending colon, including the caecum, followed by the transverse colon, including both hepatic and splenic flexure, descending colon, sigmoid colon and rectum. The peak incidence for lipomata of the large bowel is in fifth-sixth decade. Colonic lipomas are generally asymptomatic but occasionally patients may have intermittent crampy abdominal pain secondary to intussusception of a pedunculated lipoma or with intermittent fresh rectal bleeding. On barium enema lipomas appear circular, ovoid, well demarcated, and smooth. A barium enema showing a relatively radiolucent mass, caused by the radiolucency of fat, is suggestive of a lipoma. The water enema, with water as the contrast agent, accentuates the difference in density between a lipoma and surrounding tissues. Another characteristic feature of lipomas on barium enema is said to be their fluctuation in size and shape during the study: "squeeze sign". Lipomas of the large bowel can be seen, however, by colonoscopy. On computerized tomography scan the lipoma has a uniform appearance and density. In expert hands pedunculated and sessile lesions can be removed endoscopically, but often large bowel lipomata are treated on the basis of a presumptive malignant diagnosis with exploratory laparotomy. CONCLUSION. Colonic lipomas, although unusual, continue to present difficulties in the preoperative differentiation between malignant and benign colonic neoplasm. Two cases of colonic lipomas are reported.

Open colectomy versus laparoscopic colectomy: are there differences?

Laparoscopic colectomy has been increasingly reported as an option for the treatment of colonic pathology. However, there is very little information regarding perioperative morbidity and the cost effectiveness of this technique. The purpose of this study is to review our first year of experience with laparoscopic colon resection. Data collected includes: age, technique (open laparotomy, laparoscopic, laparoscopic/converted open), Karnofsky score, complications, specimen size/nodes, OR time, hospital stay, and cost. This is a consecutive series of 140 elective colonic resections including 102 open laparotomies (O) and 38 laparoscopic (L) cases. The indications for surgery have included adenocarcinoma col/rect (O = 59, L = 9), diverticular disease (O = 10, L = 10), adenomatous polyp (O = 3, L = 7), IBD (Crohn's, CUC) (O = 15, L = 4), rectal prolapse (O = 3, L = 4), and other (O = 12, L = 4). There were no significant differences with respect to age (O = 60.7 +/- 1.5; L = 54.8 +/- 3.8; C = 66.1 +/- 3.1), perioperative morbidity (O = 11%; L = 15%; C = 17%). The laparoscopic and laparoscopic converted cases required significantly more time compared to the open laparotomy group (O = 2.1 +/- 0.2 hours; L = 2.9 +/- 0.2; C = 3.4 +/- 0.2). There were significantly less intraoperative blood loss associated with laparoscopic procedures compared with either open or converted groups of patients (O = 687 +/- 54 cc; L = 157 +/- 19; C = 491 +/- 50).(ABSTRACT TRUNCATED AT 250 WORDS)

New applications of laparoscopy in gastrointestinal surgery.

Although laparoscopy has been available since the turn of the century, the technique did not become widely accepted for gastrointestinal surgery until it was used in cholecystectomy. Since then, various gastrointestinal operations have been performed using laparoscopic guidance. Laparoscopic operations must conform to principles for open general surgery, especially in cases of oncologic resection. Procedures for treatment of conditions such as hiatal hernia, gastroesophageal reflux, intractable peptic ulcer disease, bypass for malignant pancreatic obstruction and repair of rectal prolapse have received immediate acceptance. Other procedures, such as Whipple's operation and colectomy for cancer, have met with a more guarded response.

[Evisceration of the small intestine due to rectum rupture].

Evisceration of the small intestine from the anus due to a rectal rupture was diagnosed in two patients, males aged 93 and 25 years. The former had had a rectal prolapse for years; the evisceration occurred after a fall from the bed. The lower abdomen of the second patient was caught between the counterweight of a bridge and a wall. Laparotomy in both patients revealed a rupture in the ventral portion of the rectosigmoid, but no pre-existent lesions in this part of the intestinal wall. Treatment in the first patient consisted of resection of the rectosigmoid with creation of an end colostomy, the eviscerated intestinal tract being repositioned in the abdominal cavity after thorough cleansing. In the second patient the eviscerated intestinal tract had to be resected. In this case also, an end colostomy was created and the rupture in the rectum was closed transanally. Both patients recovered well.
