Pulmonary influences on early post-operative recovery in patients after cytoreductive surgery and hyperthermic intraperitoneal chemotherapy treatment: a retrospective study

Table 5 Pulmonary adverse events occurring in 62 patients (60 radiographs and 2 computed tomography scans) during post-surgery week 1, and comparison between gradations performed by radiologist 1 and 2

	Radiologist 1	Radiologist 2	Cohen’s weighted κ value
Atelectasis (n)
None (grade 0)	20	14
Lamellar atelectasis (grade 1)	13	15	0.45
Segmental atelectasis (grade 2)	23	8
Lobar and larger than lobar (≥ grade 3)	6	25
Pleural effusion (n)

Abbreviations: CHF, congestive heart failure.
^aModerate heart failure.
Six patients developed extensive atelectasis (≥ grade 3). Major pleural effusion (grade 3) was observed in seven patients and signs of heart failure (grade 1–2) developed in nine patients. Two patients developed pneumonia, one had empyema, and another patient developed respiratory insufficiency. Cohen’s weighted value κ, indicated a moderate level of agreement between the two radiologists.
