| Abstract |
PURPOSE
A total or a subtotal abdominal colectomy and a total proctocolectomy are performed occasionally for the surgical treatment of familial adenomatous polyposis, multiple colorectal cancers, ulcerative colitis, acute lower GI bleeding, and malignancy other than colorectal cancer. We studied 30 cases of patients who received either a total or a subtotal abdominal colectomy and a total proctocolectomy in one of the three hospitals affiliated with the Catholic University between January 1990 and December 2001. Our goal was to determine whether the total or subtotal abdominal colectomy and the total proctocolectomy are difficult and complicated procedures by comparing the mortality, the morbidity, the survival rate, and the complications to previously considered and reported results.
METHODS
Thirty patients treated with either total or subtotal abdominal colectomy and with a total proctocolectomy from January 1990 to December 2001 were chosen for this study. Their gender, age, underlying diseases, family history, hospital days, symptoms, changes in defecation habits following the procedure, complications, mortality, survival rate, and relationship to malignancy were evaluated.
RESULTS
Of the patients who received either total or subtotal abdominal colectomy and a total proctocolectomy, the average age was 44.6 years, the gender ratio was 1:1, and the underlying diseases were familial adenomatous polyposis (FAP) (43%), ulcerative colitis (UC) (20%), multiple colorectal cancers (17%), stomach cancer (7%), and Crohn's disease (3%). Diarrhea and rectal bleeding were the most common clinical symptoms, and abdominal pain and intestinal obstruction were frequently observed. A total proctocolectomy (TPC) with permanent ileostomy was the most frequently performed procedure (47%), and a TPC with ileoanal anastomosis was done in 10% of the cases. A total abdominal colectomy (TAC) with ileorectal anastomosis was applied in 23% of the cases, and subtotal abdominal colectomy (sTAC) with ileosigmoidal anastomosis was done in 20% of the cases. The operative mortality rate was 3% as one patient among thirty died. Postoperative complications developed in 33% of the patients. FAP and UC patients without cancer (45%) survived for over 4 or 5 years, but FAP and UC patients with cancer, especially an adenocarcinoma, survived for only 2.5 years.
CONCLUSIONS
A total or subtotal abdominal colectomy (TAC or sTAC) and a total proctocolectomy (TPC) are appropriate procedures with low mortality, low morbidity, and a low complication rate for several kinds of diseases. A TPC with ileorectal anastomosis is the procedure of choice for sparing the rectum in FAP and UC patients without coexisting cancer and without mutation of the APC gene after codon 1250, but a TPC with ileoanal anastomosis is recommended if there is a mutation of the APC gene after codon 1250. A TPC with ileostomy is the preferred method for FAP and UC patients with coexisting cancer. |
