Complicated Taeniasis necessitating surgical intervention is extremely rare and is usually reported to occur in the distal ileal region of the Gastrointestinal tract. A case of peritonitis secondary to proximal jejunal perforation due to Taenia saginata is presented. Preoperative evaluation suggested the diagnosis of acute duodenal ulcer perforation. Although no real change in management and outcome is present, Taenia remains an exceptional direct cause of intestinal perforation, and should be kept on the list of differential diagnosis of peritonitis and acute abdomen in endemic geographical locations.

In this study, the effect of hyperthermia on immune response and bacterial translocation from the gut in jaundiced rats was assessed. In hyperthermic (HP; N = 8) and normothermic (NP; N = 8) preconditioning groups, rats were preconditioned by hyperthermia for 15 min at 42 degrees C or 38 degrees C, respectively. After 8 hr, the common bile duct (CBD) of each animal was ligated. In thermal (TT; N = 8) and normothermic treatment groups (NT; N = 8) the CBD of the animals was ligated, and after seven days rats were treated by hyperthermia for 15 min at 42 degrees C and 38 degrees C, respectively. The rats in the preconditioning groups (HP and NP) were killed at day 7 and rats in the treatment groups (TT and NT) were killed 8 hr after they were put in a water bath. Determination of the immunophenotypes of lymphocytes and serum levels of bilirubin was done in serum samples taken just after death. The quantity and identify of translocated bacteria were determined in tissue samples of mesenteric lymph nodes, spleen, and liver. NK cell expression as well as CD4+/CD8+ ratio were elevated in HP group when compared to NP group. CD8+ expression was found to be low in HP group when compared to NP group. CD4+, CD11b+, and B cell expressions were not found to be different between HP and NP groups. All immunologic parameters were similar when TT and NT groups were compared to each other. In the TT group, half of the rats revealed bacterial translocation, whereas in all other groups, we determined translocation in only 1/8 rats. The application of hyperthermia as preconditioning rather than applying it after the establishment of jaundice seemed to be beneficial. Hyperthermic preconditioning led an improvement in immune responses whereas the latter resulted an increase in bacterial translocation with no favorable influence on immune system. Bacterial translocation was unrelated with the immune status.
