    Perforation of acalculous cholecystitis associated with localized atherosclerosis: Report of a case (1997)
    Springer
    Surgery today 27 (1997), S. 357-359 
    Details
    ISSN: 1436-2813
    Keywords: acute acalculous cholecystitis ; atherosclerosis ; perforation of the gallbladder

    Notes: Abstract We describe herein the unusual case of a 68-year-old Japanese man who underwent laparotomy for an acute abdomen caused by diffuse peritonitis, which revealed perforation of the gallbladder without any stones. A cholecystectomy was subsequently carried out, and histological examination showed marked atherosclerosis of the gallbladder associated with acute inflammatory changes. It is most likely that circulatory disturbance of the gallbladder wall due to the atherosclerosis played an important role in the events leading to perforation. Acute acalculous cholecystitis is an uncommon condition which is extremely difficult to diagnose preoperatively. The clinicopathological features of this patient are of particular interest and importance in terms of pathogenesis as well as treatment.

    Ampullary carcinoma in familial adenomatous polyposis: Report of a case (1996)
    Springer
    Surgery today 26 (1996), S. 522-526

    Notes: Abstract We report the case of a 48-year-old man with familial adenomatous polyposis (FAP) who was found to have ampullary carcinoma 6 years after undergoing total colectomy. The patient was examined periodically after colorectal surgery except for duodenoendoscopy because he had also previously undergone distal gastrectomy with gastrojejunal anastomosis for a duodenal ulcer at 27 years of age. An ampullary lesion was suspected on blood chemistry and detected by computed tomography scan and ultrasonography although the patient showed no clinical symptoms. A pancreatoduodenectomy was performed and the histological examination revealed well-differentiated adenocarcinoma with no metastasis to the regional lymphnodes. Long-term periodic surveillance of the upper gastrointestinal tract including the papilla of Vater is therefore important for FAP patients who have undergone prophylactic colectomy.

    Pancreatic growth after distal small bowel resection is altered with aging (1995)
    Springer

    Notes: Abstract We have examined age-related changes in the stimulatory effects of distal small bowel resection on the growth of the pancreas and on polyamine biosynthesis. Two groups of male Fischer 344 rats (young; 4-month-old, aged; 25-month-old) underwent either 70% distal small bowel resection or transection of distal small bowel (control). Rats from each treatment group of each age were sacrificed on the 10th or 20th postoperative day (POD), and pancreas was weighed and assayed for DNA, RNA, and protein contents as well as polyamines. We found that young rats with distal small bowel resection exhibited significant increases in pancreatic weight, RNA, protein, putrescine, and spermine contents on the 10th POD, but aged rats that had undergone resection, showed only increased spermine content. On the 20th POD distal small bowel resection increased pancreatic weight, DNA, RNA, and protein as well as spermidine and spermine contents in young rats; aged rats had increased pancreatic weight only. These findings suggest that the trophic responses of the pancreas to distal small bowel resection are altered in aged rats, and that the polyamine biosynthetic pathway appears to be involved in this impaired response.

    Age-related changes in duodenal adaptation after distal small bowel resection in rat (1993)

    Notes: Abstract Two groups of male Fisher 344 rats (young: 4 months old; aged: 25 months old) underwent either 70% distal small bowel resection or sham operation (small bowel transection). Rats from each treatment group of each age were sacrificed on the 10th (N=15: young rats;N=13: aged rats) or 20th (N=15: young;N=13: aged) postoperative day (POD), and the duodenal mucosa was weighed and assayed for DNA, RNA, and protein contents, as well as for specific activities of the disaccharidase, sucrase, maltase, and lactase. Compared to the sham operation, distal small bowel resection significantly increased DNA by 48%, RNA by 122%, and protein by 75% in young rats and DNA by 40%, RNA by 92%, and protein by 71% in aged rats on the 20th POD. Both young and aged rats showed similar adaptive hyperplasia on the 10th POD. On the 20th POD after distal small bowel resection, specific activities of all tested enzymes were significantly increased in young rats (sucrase +86%, maltase +110% and lactase +64%), but showed no significant changes in aged rats. These findings suggest that the duodenum of aged rats may have sufficient proliferative potential to respond to distal small bowel resection, but that the mechanisms governing return of function in response to distal small bowel resection are inhibited in aged rats, compared to those mechanisms in the young.
