Abstract/OtherAbstract:
BACKGROUND: Restorative proctocolectomy is an operative procedure that in principle means proctocolectomy, preserving the anal sphincters and construction of an ileal pouch which is sutured to the dentate line. The method is used mostly in case of surgical treatment of ulcerative colitis or familial polyposis coli. The procedure means different manipulations with the distal ileum that may influence the function of gut-associated lymphoid tissues, a major subdivision of the immune system. AIM: The aim of the present investigation was to study the plasma concentration of immunoglobulins in connection with the restorative proctocolectomy operation. METHODS: Forty five patients received an ileoanal pouch (IAP) because of ulcerative colitis. Twenty seven patients were males and 18 females. The mean age was 34 (range 18-55) years. Twenty six patients were first operated on emergency by subtotal colectomy with terminal ileostomy. In a second operation, the rectum was excised and an ileoanal pouch and a loop ileostomy that diverted the bowel content from the distal ileum was performed. Eighteen elective patients had their colectomy performed at the same time as the pouch operation. As a last procedure the diverting loop ileostomy was closed and thereby the distal ileum and the ileoanal pouch was put into function. Blood samples for plasma immunoglobulin analyses was collected from the patients before the colectomy, after colectomy with terminal ileostomy before construction of the pouch, during the period with pouches prior to loop ileostomy closure and 12 months after its closure. Immunoglobulins in plasma were determined by nephelometry method. The data was analyzed statistically by ANOVA and linear regression analysis. RESULTS: There was a significant difference preoperatively, in plasma immunoglobulin G (P-IgG) between the patients who were operated on electively compared to the emergency patients (p < 0.03). This was the only significant difference between values for the emergency and elective groups throughout the study. In the emergency patients after colectomy and with terminal ileostomy plasma immunoglobulin A (P-IgA) and immunoglobulin A (P-IgM) concentrations in plasma had increased significantly compared to preoperative (p < 0.03) and (p < 0.002) respectively. During the time with loop ileostomy plasma IgM was still found to be significantly elevated (p < 0.02) compared to the level before colectomy. In the electively operated patients plasma IgA and IgM were significantly increased after colectomy and pouch construction during the time with loop ileostomy compared to preoperatively (p < 0.04) and (p < 0.0004). After 12 months with functional pouches the plasma immunoglobulins in both groups were similar to the elective patients preoperatively. CONCLUSION: The immunoglobulins IgG, IgA and IgM were studied in connection with restorative proctocolectomy. Preoperatively, IgG was found to be significantly lower in emergency compared to elective patients. The difference is probably due to increased losses and impaired production of IgG in the acute phase of ulcerative colitis. IgA and IgM were found to increase significantly after colectomy and construction of an ileostomy but how these measures were responsible for the changes could not be determined in the present study. Twelve months after loop ileostomy closure there were no longer any significant changes of the immunoglobulins compared to elective patients with ulcerative colitis preoperatively.
