Permanant ileostomy is necessary in the case of a total proctocolectomy for a cancerous change in the distal rectum due to ulcerative colitis or familial adenomatous polyposis coli, but the fecal content after a conventional ileostomy is usually liquid or semiliquid. Sometimes, this resultes in dehydration and some nutrient loss. Nahm-gun Oh has designed an antiperistaltic ileostomy for formed stool evacuation. About a 25 cm length of the most distal ileum is cut, this segment is reversed, and then the antiperistaltic ileostomy is performed. The authors have performed antiperistaltic ileostomies in 6 cases of familial adenomatous polyposis or ulcerative colitis with a cancerous change in the low rectum. During the past 5 years and 7 months at the Department of Surgery, Pusan National University Hospital, we found that the profuse ileostomy discharge of the conventional ileostomy was decreased in the antiperistaltic ileostomy group, and that the antiperistaltic ileostomy discharge had a liquid component which was markedly decreased compared to that of the conventional ileostomy discharge. In addition, the antiperistaltic ileostomy discharge appeared to be much more solid and less voluminous. In conclusion, the antiperistaltic ileostomy should be considered for creating the effect of a reservoir by producing intestinal stasis proximal to the segment. The antiperistaltic ileostomy is effective in reducing the daily amount of ileostomy discharge and is convenient for stoma care due to the diminished water content in the discharge.

BACKGROUND: It has been shown that L-type calcium channel blockers increase the muscle relaxation effects of non-depolarizing neuromuscular blocking agents whereas the potentiated neuromuscular blocking effects by L-type calcium channel blocker are resistant to reversal by neostigmine. The aims of this study were 1) to see whether the pretreatment of L-type calcium channel blocker, such as verapamil, aggravates the pipecuronium-induced muscle relaxation, 2) if so, to see whether these effects are reversed by anticholinesterase, such as neostigmine and edrophonium or potassium channel blocker, such as 4-aminopyridine. METHODS: The rat-phrenic nerve-hemidiaphragms (n=60) were prepared. Twenty microgram of pipecuronium was administered to all organ bath. All samples were divided into two groups according to the administration of 10uM of verapamil i.e. verapamil pretreated, non-pretreated group. The amounts of administered pipecuronium were gradually increased by 4ug until the force of twitch decreased to 10% of control value in both groups. Each group was subdivided into three groups according to the administration of 0.75 M of neostigmine, 12.4 uM of edrophonium or 40uM of 4-aminopyridine. RESULTS: The dose of pipecuronium required for the decrease of contractile force to 10% of control value was less in verapamil pretreated group than in non-pretreated group. And, the decrease of contractile force in both groups was more effectively reversed by 4-aminopyridine than neostigmine and edrophonium. CONCLUSIONS: Verapamil potentiates the pipecuronium-induced neuromuscular blockade and 4-aminopyridine is more effective to reverse verapamil pretreated, pipecuronium induced neuromuscular blockade.

The first successful bone transplantation carried out in 1688 by Van Meek'ren, a Dutch surgeon. The ideal bone substitute should be biocompatible, osteoinductive or at least osteoconductive, available in unlimited quantity, low cost and have satisfactory mechanical properties. To accomplish these goals, autografts are still preferred material. However, bone harvesting procedures have been focused to solve the following problems; necessity of a second surgical site, morbidity and potential deformity of the donor site, an increased operative time, donor availability limitations, and resorption of autogenic bone grafts.Ten adult white New Zealand rabbits, three, 10 mm in diameter, full layer skull defects were made in the frontoparietal bone. Two bone defects were filled with hydroxyapatite and powdered eggshell, the other defect was not filled(control). All animals were sacrified at 10 weeks, the specimens were examined macroscopically to test for graft mobility. The graft with surrounding bone was then harvested and studied by histology. The results were as follows: 1. Control: Bone regeneration occurred nearly complete. 2. Hydroxyapatite: Macroscopically - No encapsulation. Despite a gross delineation between implant and bone, imlant was firmly united to bone. Histology - Bony trabeculae surrounded by proliferated connective tissue are observed in the defect site and implant. Osteoblastic rimming is noted along the bone fragments 3. Powdered eggshell:Macroscopically - Grafted site was encapsulated by proliferated connective tissue and palpable softer than the surrounding bone. Histology - The presence of eggshell particles encapsulated by fibrous connective tissue. Partial bone regeneration from the defect margin was noticed, but the bone healing was never complete. In conclusion, the use of safe and inexpensive material is recommended for filling limited bone defects in non-weight bearing areas. The use of powdered eggshell for bone substitute may also be considered, after further studies, to access its long term stability, porosity and biocompatibility.
