Influence Of Age, Comorbidity, Type Of Operation And Other Variables On Lethality And Duration Of Post Operative Hospital Stay In Patients With Peptic Ulcer - An Analysis Of 303 Surgically Treated Patients

Three hundred and three consecutive patients operated on for peptic ulcer for the first time between 1 January 1984 and 31 December 1993 were evaluated in this retrospective study. Eleven variables (Period when operation took place, gender, smoking behaviour, history of former ulcers, ulcerogenic drug intake, ulcer location, epigastric pain, number of blood units substituted, patient's age, type of operation, comorbidity) were investigated regarding their influence on peri- and post-operative mortality and on the length of hospital stay after operation. We found that a high comorbidity score (>2) and the indication ''emergency operation'' (vs ''elective operation'') had an adverse impact on survival. The importance of age was marginal. The duration of post-operative hospital stay in survivors was negatively influenced by age higher than 60 years, more than two red cell units substituted and a high comorbidity score according to Charlson.
