The blind pouch syndrome.

The blind pouch syndrome is a series of symptoms associated with blind pouch formation, secondary to a side-to-side intestinal anastomosis. The diagnosis is easily suspected in a patient with anemia, episodes of diarrhea, intermittent crampy abdominal pain, weight loss and a history of a previous abdominal operation. The effectiveness of intubation-infusion barium studies of the small intestine in demonstrating obscure lesions therein, undetected by conventional methods, should be used for a prompt and precise diagnosis preoperatively. Surgical correction by means of resection of involved lateral anastomosis with end-to-end anastomosis has been successful, eliminating future complications.

Retained barium n the appendix: diagnostic and clinical significance.

The significance of prolonged retention of barium in the appendix in an asymptomatic patient has been debated. Four patients, with retained barium in the appendix for several months after gastrointestinal barium studies, who then developed acute appendicitis, are reported and analyzed. Thirty-one patients who retained appendiceal barium longer than 72 hr after radiographic examination of the gastrointestinal tract were followed for over 1 year. No patient developed appendicitis. Five patients underwent abdominal surgery for other indications and there was no evidence of appendicitis. In 11 patients, who had abdominal radiographs 6 days to 4 months after detection of appendiceal barium, the barium had disappeared. The connotation of the term "barium appendicitis" as initially reported is questioned. Preliminary data in this report suggest that no causal relationship exists between prolonged retention of barium and future acute appendicitis and that normal appendices can expel barium in variable time periods. Etiologic connotation between prolonged appendiceal barium retention and future acute appendicitis should be erased. Retained barium in the appendix can be used as an acid in the precise radiographic diagnosis of acute appendicitis.

Meckel diverticulum: radiologic demonstration by enteroclysis.

Thirteen patients with surgically confirmed Meckel diverticula encountered in a 30 month period are reported. Of 11 symptomatic patients, all had lower gastrointestinal bleeding, except one who had recurrent abdominal pain only. Two diverticula were incidental, coexisting with Crohn disease of the distal ileum. One of these had occasional diarrhea and hematochezia. The diagnosis was established preoperatively by enteroclysis in 11 of these cases. The enterographic demonstration of the mucosal triangular plateau or the triradiate fold pattern indicating the site of exit of the omphalomesenteric duct should lead to a diagnosis of Meckel diverticulum. Pitfalls in interpretation due to the pseudotriangular plateau appearance formed by superimposition of two intestinal loops and the pseudosaccule produced by the axial projection of a fixed loop of bowel and the differential diagnosis are discussed. Enteroclysis seems to be the most dependable method currently available for preoperative demonstration of Meckel diverticulum.

Gastrointestinal perforation by chicken bones.

Four cases of gastrointestinal perforation by chicken bones are presented. Variability in the clinical manifestations generally precludes a correct preoperative diagnosis of intraabdominal chicken bone abscess. However, in 2 patients, a diagnosis was possible with plain abdominal radiographs. Although the abnormalities seen were nonspecific, the identification of a chicken bone with an associated mass or extraluminal gas collection in a patient with signs of peritonitis, mechanical bowel obstruction, or pneumoperitoneum strongly suggests the diagnosis. A history of alcoholism or wearing dentures strengthens it.

"Blind pouch" syndrome: a cause of gastrointestinal bleeding.

A case of blind pouch formation presenting as gastrointestinal bleeding 23 years following side-to-side small bowel anastomosis to relieve obstruction is reported. Although rare, blind pouches may occasionally be encountered. Familiarity with the clinical and radiographic features can aid in a prompt and precise preoperative diagnosis.

Nasointestinal tube for decompression or enteroclysis: experience with 150 patients.

The initial clinical experience with the use of a triple lumen long tube designed for gastrointestinal decompression and enteroclysis is reported in 150 patients. Based on clinical observations, this tube is effective in suctioning retained gastric and intestinal fluid but requires frequent irrigation of the sump port for effective decompression of distended small bowel. In all patients with a preexisting nasogastric tube, the replacement by the decompression/enteroclysis tube was considered more comfortable by the patients. Successful placement of the tube in the jejunum was achieved in 147 of 150 consecutive patients on the initial attempt. The use of this tube obviates dual intubations for decompression and enteroclysis, the attendant discomfort on the patient, and it expedites subsequent performance of enteroclysis if needed. The complications reported with other long intestinal tubes were not observed with this device.

Barium trapping in rectoceles: are we trapped by the wrong definition?

BACKGROUND: Barium trapping within a rectocele is a criterion used by surgeons to select which patients with rectoceles should undergo operative repair. This proctographic study compared the presence and depth of barium trapping within a rectocele on postevacuation radiography with those seen on posttoilet radiography after further evacuation in the privacy of the bathroom. METHODS: Eighty-two consecutive patients with evidence of barium trapping on postevacuation radiographs of a fluoroscopic dynamic cystoproctographic examination were reviewed retrospectively. The size of the rectoceles and the depth of barium trapping on the postevacuation and subsequent posttoilet radiographs were measured. RESULTS: The posttoilet radiographs showed resolution of the barium trapping in 47 (57%) of the 82 patients. Resolution of the trapping was directly related to rectocele size. The mean differences in the depth of barium trapping between the postevacuation and posttoilet radiographs were significant for all sizes of rectocele. CONCLUSION: Barium trapping in rectoceles changes with the degree of rectal evacuation. More complete evacuation was shown on the posttoilet radiograph than on the postevacuation radiograph. Consequently, the posttoilet radiograph may be more appropriate for the preoperative assessment of barium trapping within rectoceles.

Current status of small bowel radiography.

BACKGROUND: In the past, small bowel examinations were usually ordered for the sake of "completeness." As a result, small bowel radiography was performed casually and without attention to detail. This review examines pertinent clinical issues and the recent contribution of small bowel radiography to the evaluation and management of the patient with suspected small bowel disease. Recommendations for the clinical utilization of small bowel radiography are discussed. METHODS: Analysis of pertinent citations addressing valid indications for, and technique of, small bowel radiography from 1980 to July 1995 through a computerized bibliographic search (Medline and Current Contents). RESULTS: Accepted clinical indications for small bowel radiography include (1) unexplained gastrointestinal bleeding, (2) possible small bowel tumor, (3) small bowel obstruction, (4) Crohn disease, and (5) malabsorption. The current literature reflects the limitations of the conventional small bowel follow-through, various modifications to improve its clinical yield, the important contribution of enteroclysis in the workup, and subsequent management of patients with possible small bowel disease. A controversy in the radiology literature exists as to whether to use the small bowel follow-through or enteroclysis as the primary method of examining the small bowel. CONCLUSION: The thoughtful selection of patients by clinicians for small bowel radiography is essential to make radiologic evaluation cost effective. The incidence of disease of the small intestine is low and is associated with nonspecific symptoms. Because of the inherent difficulty of visualizing numerous loops of an actively peristalsing bowel, a reliable imaging method is needed that not only detects small or early structural abnormality but also accurately documents normalcy. The yield of information provided by enteroclysis and its high negative predictive value suggests that it should be the primary method for small bowel examination. The "overhead"-based conventional small bowel follow-through should be abandoned. The "fluoroscopy"-based small bowel follow-through augmented when necessary by the peroral pneumocolon or the gas-enhanced double-contrast follow-through method is an acceptable alternative when enteroclysis is not possible.

Clinical utility of enteroclysis.

The incidence of pathology in the small bowel is substantially lower than in the upper gastrointestinal tract or colon. This is fortunate since the small bowel, with its unique anatomy and remote location is the most difficult section of the gastrointestinal tract to study. Instillation of contrast into the small bowel lumen can be achieved by the oral route or by the more recently refined technique of small bowel intubation/infusion called enteroclysis. This brief review will focus on the clinical infusion indications for and efficacy of enteroclysis and the relative advantages of enteroclysis over oral methods of small bowel radiography.
