Fused epiploic appendages simulating carcinoma of the left colon.

A 60-year old male with a history of rectal bleeding was operated upon because of the finding of a filling defect on barium enema examination. At operation it was found that the defect was produced by the fusion of two epiploic appendages. Following release of the adhesion the colon regained its normal appearance and postoperative barium enema showed no pathological findings.

Retroperitoneal dissection of a pancreatic pseudocyst to the left inguinal region.

We describe a patient in whom retroperitoneal dissection of an infected pseudocyst of the pancreas into the left inguinal region imitated an incarcerated hernia. The high level of diastase (32,000 units/ml) in the fluid from the inguinal region and the roentgenologically demonstrated communication between the pancreas and the left inguinal region proved that the source of the fluid was the pancreas. The appearance of a mass in the inguinal region in an alcoholic patient who has recently had pancreatitis should arouse suspicion of an origin in a dissecting pseudocyst of the pancreas.

The influence of biliary infection on the postoperative course after biliary tract surgery.

A prospective clinicobacteriological study was undertaken in 167 patients undergoing biliary surgery so as to assess the possible influence of the endogenous preoperative biliary infection on postoperative morbidity. Bile cultures were positive in 33% (55 patients); in those undergoing cholecystectomy alone this finding was present in 23% while in those in whom a choledochotomy was also performed cultures were positive in 65%. The incidence of wound infection was found to be twice as high in those undergoin choledochotomy as in those undergoing cholecystectomy alone--37.8% vs. 18.5%. There was no appreciable difference in the rate of wound infection when a routine appendectomy was performed during biliary tract surgery. Among the 38 patients with wound infection, bile cultures were positive in 16. In 13 cases the offending organism in the wound was identical with that recovered from the bile coulture. This finding suggests an endogenous source for the wound infection. This study further indicated that wound infection is most likely to be encountered in patients with pathogenic organisms in the bile, in the aged and in those whose resistance to infection has been lowered by concomitant disease.

Spontaneous biliary-enteric fistulas; some considerations on the management of gallstones.

During the past ten years a diagnosis of biliary-enteric fistula was made in thirty-five patients. Six were entirely asymptomatic and another seven patients had suffered only mild symptoms for a short period of time. This indicates that the gallbladder can undergo recurrent episodes of inflammation to the point of fistula formation, with little or no clinical signs of symptoms. An aggressive surgical approach is therefore warranted in patients with cholelithiasis, even when silent stones are involved.

Colonic atresia associated with Hirschsprung's disease.

A rare case of an infant with both atresia of the colon and Hirschsprung's disease is described. The diagnosis of Hirschsprung's disease was fortuitously made on histological examination of the resected colon. The importance of being aware of the possibility that these two conditions may coexist is stressed.

Staged orchiorrhaphy. Therapeutic procedure in cryptorchic testicle with a short spermatic cord.

In 62 planned staged orchiorrhaphies for a "short" spermatic cord, satisfactory location of the testicle following the second operation was achieved in 90% of cases. The testicle was atrophic and had to be excised in only 3.2%. After a follow-up period of two to ten years, the testicle remained satisfactorily located in 77% of cases; adequate size and configuration of the testicle (compared to the contralateral side) was found in 64.5%. In 17%, a partial or complete atrophy developed. No correlation was found between the initial size of the testicle and the late results. It is advocated, therefore, that excision be avoided unless definite atrophy exists. Planned staged orchiorrhaphy is recommended for testicles in high locations that are difficult to bring down. The late preschool period (5 to 6 years) is suggested as the optimal age for the first attempt at orchiorrhaphy and the second stage two years later, if required.

Gamma-glutamyl transpeptidase as an aid in the diagnosis of liver metastases.

Serum gamma-glutamyl transpeptidase (GGTP) activity was examined in 79 patients. Of these, 49 had diverse malignant tumors, some of which had metastasized to the liver, and 18 had benign diseases of the liver, gallbladder and bile ducts. Enzyme activity increased significantly in all but two patients in whom liver metastases were found. All but one of the patients with malignant tumors, but without liver metastases, showed normal GGTP activity. GGTP activity was elevated in all cases of jaundice. In the absence of jaundice, elevated GGTP activity is suggestive of the presence of liver metastases.
