Abstract
Although appendectomy is the most commonly performed emergency operation septic complications of appendectomy remain a major source of morbidity. Historically, advanced appendicitis has been treated by appendectomy with cecostomy and/or drainage tubes. Our objective was to evaluate the use of ileocecal resection for the immediate treatment of advanced appendicitis. We examined the cases of all patients undergoing ileocecal resection for appendicitis from August 1989 through April 2000. There were 92 patients (60 male and 32 female) with a median age of 34 (range 6–71). Abdominal pain was present in 98 per cent of patients with duration of 5.1 ± 0.6 days. Right lower quadrant tenderness was present in 91 per cent with accompanying right lower quadrant mass in 30 per cent. Temperature on admission was 38.0 ± 0.1° C with a white blood cell count of 15,300 ± 500. Preoperative radiological studies included abdominal X-rays (33), contrast enemas (two), CT scans (41), and abdominal ultrasound (17); these studies yielded a correct preoperative diagnosis in 89 per cent. Previous appendectomy had been performed in six patients with failed percutaneous drainage of intra-abdominal abscesses in five. There were 94 cecal resections performed in 92 patients. The extent of surgical resection varied between patients and ranged from partial cecectomy (34) to ileocecectomy (55) to ileocecectomy with diverting ileostomy (five). Intra-abdominal abscesses were present at operation in 46 cases (50%), and drains were placed in 38 (41%). Skin incisions were packed open in most cases (65); there was skin closure in 27. There was no mortality encountered in this period. There were 25 complications in 23 patients (25%). Complications included postoperative abscess (10; 11%), wound infection (10; 11%), partial small bowel obstruction (two) and pulmonary embolus (one). Reoperation was required in seven patients and CT-guided percutaneous drainage in five patients. Anastomic leaks occurred in two cases of partial cecectomy and required conversion to ileocecectomy. Mean hospital stay was 10.5 ± 1.0 days with adjusted hospital costs of $31,689 ± 3018. We conclude that definitive treatment of advanced appendicitis can be performed by resection of the involved areas of the ileocecum. This can be accomplished with a primary anastomosis obviating the need for ileostomy and secondary operation. This aggressive surgical approach may reduce infectious complications and reduce hospital costs.
