Translocation of bacteria due to direct mucosal damage caused by Gastrografin. An experimental study in newborn rats.

A study was carried out on 40 newborn rats to determine the effect of Gastrografin (a hyperosmolar solution, 1700 mosm/liter) on the gastrointestinal tract. All the newborns received an inoculum of Klebsiella bacteria to the gastrointestinal tract. Thirty received, in addition to maternal milk, a feeding of Gastrografin twice daily. The Gastrografin was found to cause severe and irreversible damage to the mucosa of the small intestine, causing the death of 24 rats less than a week after start of the experiment. The 10 rats who received no Gastrografin and served as controls showed no signs of disease or damage to the intestinal tract. Cultures taken from the peritoneal cavity after sacrifice were all positive for Klebsiella in the Gastrografin group (30 rats) and negative in the controls (10 rats). This study has therefore demonstrated that severe damage to the small intestine mucosa will lower the intestinal barrier and lead to transmural translocation of bacteria into the peritoneal cavity.

Oncogenic osteomalacia induced by schwannoma in a patient with neurofibromatosis.

A 62-year-old woman known to be suffering from Von Recklinghausen disease and osteomalacia was operated on for a pelvic mass. Pathological examination of the excised tumor showed it to be a schwannoma and this tumor was considered to be responsible for the osteomalacia. The return of previously abnormal laboratory data to normal values and the impressive clinical and subjective improvement further support the assumption that the excised schwannoma was responsible for the pathology observed in this patient.

Penetrating stab wound of the gluteus--a potentially life-threatening injury: case reports.

Presented are two cases of stab wounds through the gluteus in which serious damage was incurred by internal organs: in one case there was penetration of the rectum with the appearance of signs of acute abdomen; in the other there was tearing of retroperitoneal muscles and the internal iliac vessels with resultant hypovolemic shock. These observations suggest that there should be greater awareness of the life-threatening nature of stab wounds of the gluteus under similar circumstances.

Massive haemoperitoneum complicating metastasis in the liver.

The rare phenomenon of gross intra-abdominal bleeding due to hepatic metastasis was seen in a young male who a short time before had undergone orchiectomy because of embryonal cell carcinoma. Following laparotomy, 4 liters of fresh blood were drained from the peritoneal cavity and the left lobe of the liver, containing a single large metastasis, was removed. It is stressed that when no other cause of such haemorrhage can be found in a patient known to have had malignancy, the possibility of bleeding from a metastasis should be considered and appropriate measures taken.

Comparative study for preoperative staging of rectal cancer.

A comparative study of preoperative evaluation of rectal cancer is presented. Sixty-eight patients with rectal cancer were examined digitally and by computerized tomography and transrectal ultrasound. Preoperative staging was compared with pathologic findings at surgery. Digital examination and transrectal ultrasound were accurate in 82.8 and 76.2 percent, respectively and were superior to CT, which was accurate in 65.5 percent of cases for assessment of rectal wall invasion. All three modes play a role in preoperative assessment, but digital examination and rectal ultrasound appear to be more effective.

Local recurrence after low anterior resection using the EEA stapling device.

Fifty-five patients underwent curative stapled low anterior resection for rectal adenocarcinomas located 5 to 15 cm from the anal verge. Two patients (3.7 percent) died postoperatively. The mean follow-up for the remaining 53 patients was 40 months. Local recurrence was diagnosed in 17 patients (32 percent), in most (88 percent) within the first two years after surgery. Most local recurrences appeared in patients classified as Dukes' C1 and C2 but, surprisingly, no significant difference was found between rectal tumors of high and low location as regards recurrence. The high rate of recurrence in this series may be attributable to the large number of patients with advanced tumors, and poorly differentiated carcinoma, or both.

Intramural hematoma of duodenum following endoscopic intestinal biopsy.

We present the fourth case to be reported in the literature of intramural hematoma of the duodenum following endoscopic small bowel biopsy. It is the first reported to have been diagnosed by ultrasonography and confirmed by contrast roentgenograms. Conservative treatment was effective in achieving satisfactory resolution of the obstruction within seven days, as evidenced by barium meal examination. The mechanism of trauma, in light of the other cases reported in the literature, is discussed.

Free perforation of small intestine in adults.

In a 14-year period 15 cases of free perforation of the small bowel in adults were treated in our department. In two patients perforation was caused by a foreign body and in six by each of the following: duplication of the small bowel, Hodgkin's lymphoma, vasculitis and steroid treatment, intussusception, adhesions, diverticulum. All patients presented with the signs of diffuse peritonitis. One patient died before surgery. Of the 14 patients operated upon, 10 underwent resection and primary anastomosis and four suturing of the perforation. In six cases the etiology remains unknown even after surgical intervention and pathological examination. The mortality rate of the 14 operated patients was 7.1%. 78.5% of the patients were operated on within 24 hours of onset of symptoms, and early surgery is considered to be the most important factor in the low mortality rate achieved in this series.

Heterotopic pancreatic tissue in the gallbladder.

An unusual case of heterotopic pancreatic tissue found incidentally in an inflamed gallbladder is reported. The literature relating to aberrant pancreas, its origin and diverse locations, is reviewed.
