One hundred neinty two patients with enterostoms who were operated in our hospital between 1993 to 2001 were analyzed．The percentage of the colostomy and the illeostomy was 81％,19％ respectively．The background disease of these stomas were colorectal cancers(67％)and the idiopatic perforations of the colon(17％)and the others(16％)．The most popular type of enterostomas was a loop colostomy(61％)．These stomal complications of loop stomas which included stomal collapse and parastomal skin trouble were relatively higher than those of endocolostomy．It was suggested that we should make standardization of good loop-stomas for easy and good patient's stomal care on everytime and every situation．

In enterostomies,the effects of a steroid hormone on corenum function as well as the relationship between peristomal skin trouble and this function are not well understood．We examined the peristomal skin and measured transepidermic water loss and skin conductance 1-7 days before and 4-5 weeks after surgery in ileostomy patients with or without steroid hormone administration． Results showed that transepidermic water loss and skin conductance were enhanced after surgery regardless of the use of a steroid hormone,and that this tendency was significant in patients with steroid hormone administration．These findings indicate that the faceplate adhesion disturbs the corneum barrier function and moistens the skin,a tendency most marked in patients receiving a steroid hormone．

Management of a mucoimplant occurred in the peristomal skin is difficult and often unsatisfactory．We here report the case of a 56 yeas old man who developed a peristomal mucoimplant in a sigmoid colostomy．Previous treatment with silver nitrate cautery for the mucoimplant had been unsuccessful．However,the mucoimplant was successfully eradicated by CO₂ Laser cauterization．The success allowed the ostomate easy exchange of his ostomy appliance and greatly improved his quality of life．A CO₂ laser can reach deeply enough to cauterize a mucoimplant in the skin with a pinpoint range．We conclude that treatment with CO₂ laser cauterization is useful for an intractable mucoimplant of the peristomal skin．

One prime problem for patients with a jejunostomy is dehydration caused by the malabsorption of nutrients and large stomal losses of electrolytes and fluid．
This is a report of a rare case of a patient with a jejunostomy and length of residual jejunum of approximately 150cm,owing to recurrence by disseminated peritoneum after distal gastrectomy．The large output from a jejunostomy was treated by stricting the hypotonic fluid,using antidiarrheal agents-especially morphine for pain control of cancer,and the administration of isotonic fluid(Pocari Sweat TM)． The isotonic fluid was found to be effective as the output from the jejunostomy decreased from 4000ml to 2000ml and urinary volume increased．However,this was still not adequate because of a low concentration of electrolytes．For this reason,the application of electrolyte-rich ORS(oral rehydration solution)must be considered．

We present a case of an intestinal fistula caused by leakage of an ileocolostomy．Despite the application of skin protective agents around the fistula,it was difficult to have the faceplate adhere to the perifistular skin．Discharge from the fistula caused skin erosion,and frequent changes of stoma equipment depreciated the Quality of Life(QOL)of the patient．Treatment using a silicone gel sheet prevented the progression of skin erosion and improved the QOL of the patient,confirming its usefulness in the case of an intestinal fistula．
