The aim of this study was to evaluate the immediate and short-term -
follow-up results of one-stage subtotal or total colectomy and anastornosis
for patients with malignant left colon obstruction. The study comprised
21 patients (10 males and 11 females) with age range of 36-81
years; presented by acute large bowel obstruction with clinical and radiological
evidence of obstruction. The choice of the extent of resection was
determined by the extent offecal load, the presence of colonic perforation,
serosal tears of the cecurn and/or massive colonic distension with concomitant
ischemitv the presence of these features in a hemndynamkally
stable patient favored subtotal or total colectomy and deo-colic or ileorectal
anastomosis . The site of obstruction was at the sigmoid colon in 9
patients (42.9%). rectosigmoid in 8 patients (38.1%), splenic flexure in 3
patients (14.3%) and descending colon in one patient (4.7%). Reosigmoicl
anastomoses were done in 13 patients (61.9%) and 8 patients (38.1%)
had deorectal anastomoses. The mean operative time was 201+33.2;
range: 150-270 minutes, the mean operative blood loss was
683.3+408.2; range: 250-1800 cc; 11 patients (45.8%) required blood
transfusion with a mean number of blood bags used was 2.8+1.2; 1-5
bags. Oral feeding was resumed after a mean period of 4.9+0.9; range: 4-
7 days and the mean postoperative hospital stay was 10+2.2; range: 8-
18 days. Overall, after 12-months follow-up only one patient had anastomotic
line recurrence with a recurrence rate of 4.75%, one patients died of
acute liver failure secondary to hepatic metastasis with mortality rate of
4.75% and 19 patients hod follow-up free of morbidity with no local recur-rence or metastasis and a follow-up free rate of 90.5%. Thus it could be
conclutird that one-stage subtotal or total colectomy anti ileo-colic or ileorectal
anastomosis are safe procedure with satisfactory outcome for management
of obstructing malignant lesions of the left colon. |
