title: Acute appendicitis in elderly patients: a challenge for surgeons.
abstract: The classic symptoms of acute appendicitis are seldom seen in the elderly patient. More subtle symptoms and the more virulent pathologic course allow the disease to progress rapidly and insidiously. This leads to delayed hospitalization, diagnosis and treatment. The high incidence of concomitant diseases and the multiplicity of differential diagnostic possibilities in this age group are also factors. The aim of this study is to compare the results of appendicitis operated at Lumbini Medical College, Pravas, in patients younger than 60 and patient elder than 60 years of age. All patients aged 60 years and older who underwent appendectomy for appendicitis between January 2008, and December 2011, were studied and compared with the patients who were younger than 60 years of age. All the operations were performed by consultant surgeons at Lumbini Medical College, Pravas, Tansen. Preoperative USG was done in all the cases. Preoperative antibiotics were given in all the cases. All patients underwent appendectomy as an emergency basis. The results were compared with regard to age, sex, pre-operative evaluation, operative duration and findings, postoperative course, duration of hospital stay, and mortality rate. There were 50 patients in group 1 and 150 patients in group 2 who met the inclusion criteria. The mean age (64 years for group 1 and 28 years for group 2), sex, preoperative suggestion of appendicitis (group 1, 35 [70%] of 50 patients; group 2, 135 [90%] of 150 patients), and duration of the preoperative hospitalization over 24 hours (group 1, 1 patients [20%]; group 2, 30 patients [20%]) were similar in both groups. Laparoscopy was used in (group 1, 5 patients [10%]; group 2, 6 patients [4%] and associated with no significant difference in the duration of hospitalization, frequency of appendiceal perforation or abscess, occurrence of complications, or mortality. The length of operating time was more in the first group. The mean hospital stay was 5.3 in group 1 and 2.2 in group 2 (p < 0.05). Also duration of Hospital stay was 9.5 days for perforated appendicitis and 5.4 for non perforated appendicitis in both group (p < 0.05). Advanced age adversely affects clinical diagnosis, the stage of the disease and the outcomes. Late presentation, delayed diagnosis, presence of perforation and co-morbidities are associated with poor outcome from surgery.
