The sample included 122 patients who met the inclusion criteria age group most present in our study was from 40 to 50 years was 5.29%, and the least presence was within the study, the age group from 10 to 20 years was 2.8%, and thus the rest of the results are read as it (table1).
As for gender, number of males were 88 (72.1%) and they are the most present in the sample, the number of females were 34 (27.9%) as shown in (table 2).
speaking of the rate of patient acceptance over the years, the year in which patients were accepted the most was 2012, as the number of patients who were admitted to the hospital in 2012 were 42 patients (4.34%), and the number patients who were admitted in 2013 and 2014 were 28 patients (11.5%). the number of patients who were admitted in 2015 were 17 (13.9%) and the rest of the cases were distributed over the years as shown in (Table 3).
percentage of primary lung abscess in patients was (81.1%), while the percentage of secondary lung abscess was (18.9%), and the values here are not convergent at all, and there is a significant difference for as shown in (table 4).
Diagnosis was based primarily on x-ray (57.4%), followed CT scans were (29. 5%), The rest of the surveys were distributed in varying proportions, as shown in (Table 5).
Speaking of the size of lung abscess, the percentage of lung abscess that measures (4 x 5 cm) was (47.5%), while the percentage of lung abscess that measures (4 x 3 cm) was (46.7%), and the percentage of abscesses that measure (5 x 6 cm) was (4.1%) and the abscesses that measure (2 x 3 cm) and (2 x 4 cm) measuring were (0.8%) as shown in (table 6).
percentage of patients diagnosed with anaerobes was (54.1%), while the percentage of patients diagnosed with gram-negative infection was (18%), and the percentage of patients diagnosed with gram-positive infections was (11.5%), while the percentage of patients diagnosed with more than one bacterial type of the above was (16.4%), as shown (Table 7).
number of patients who were treated with chest drainage were 28 patients (23%) and were treated with specificity antibiotics of each pathogen diagnosed with bacterial cultures were 92 patients (75.4%), number of patients who were treated with surgical removal were 2 patients (1.6%), as shown in (table 8).
Percentage of patients with primary lung abscess and non-smokers (35.2%), and patients with primary lung abscess and smokers for more than 10 years (39.3%), and so the rest of the statistical results is read as shown in (Table 9).
Where death cases were significantly associated with patients with lung abscesses, the causative agent was anaerobes (4.9%), followed by gram-negative infection, followed by gram-positive infection by (3.3%) and (2.5%), respectively, and one death occurred when more than one pathogen was infected (0.8%) (Table 10).
When studying the relationship between the method of treating a lung abscess and the incidence of death, it was found that the percentage of patients who were treated with antibiotics and died (6.6%), and the percentage of patients were treated with chest blast and died (4.1%) and the percentage of patients who were treated with surgical excision and died (0.8%) (Table 11).
