Objectives

Narrative objectives1

The primary objective of this study is to clarify a difference in diagnosis rate of pulmonary thrombosis after digestive surgical operation between multi detector row CT and perfusion SPECT.
The secondary objective of this study is to identify incidence of deep vein thrombosis in patients with postoperative pulmonary thrombosis and potentialities of endothelial function test as preoperative predictive factor for postoperative pulmonary thrombosis. Furthermore, we will survey prognosis of patients with postoperative pulmonary thrombosis for two years.

Results

The postoperative PT detection rate was significantly higher for Q scan than for CTA, suggesting that postoperative PT occurs due to a mechanism other than DVT-borne thrombosis. The preoperative EndoPAT values were low in patients diagnosed with postoperative PT on CTA and in those diagnosed with postoperative PT on Q scan planar images; however, these differences were not significant. No PT-related deaths were noted.

Baseline Characteristics

mean age: 70.6 years; males: 22 (64.7%); malignant disease: 27 patients (79.4%); mean body mass index (BMI): 24.2; laparoscopic surgery: 11 patients (32.4%); open surgery: 23 patients (67.6%); mean operation time: 4.2 h; and outcomes of 2-year postoperative prognosis: survival in 30 patients (88.2%), death due to cancer in 3 (8.8%), and cerebral hemorrhage in 1 (2.9%)

Participant flow

Patients aged >20 years who met the inclusion criteria were screened for eligibility. Patients who planned to undergo elective surgery (laparoscopic or open surgery under general anesthesia) at the Department of Gastrointestinal Surgery, Shinbeppu Hospital were included.

Adverse events

none

Outcome measures

The postoperative PT detection rate for each modality (CTA and Q scan) was the primary endpoint. The secondary endpoints were as follows: DVT complication rate in postoperative PT patients, differences between endothelial function assessed by EndoPAT in the postoperative PT and no postoperative PT groups, and 2-year postoperative prognosis (all-cause mortality).

Study Population
Patients that elective digestive surgical operation under general anesthesia are planned in Shinbeppu hospital between September 1, 2014, and August 31, 2016 are eligible for enrollment if they meet the inclusion criteria.

OUTCOMES
The primary outcome is verification of a difference in diagnosis rate of pulmonary thrombosis after digestive surgical operation between multi detector row CT and perfusion SPECT.
The secondary outcome include incidence of deep vein thrombosis, endothelial function using the Endo-PAT 2000 device (Itamar Medical Inc, Caesarea, Israel), and surveillance of patients with postoperative pulmonary thrombosis for two years.
