Table 2 Incidence of perioperative deep venous thrombosis and pulmonary embolism (DVT/PE) after digestive surgery

From: Incidence of postsurgical pulmonary embolism and deep venous thrombosis: a single-center retrospective observational study

DiseaseDVT or PE cases/total number (n = 520)% (95%CI)
Hepatic cancer, pancreatic cancer5/2222.7 (7.8–45.4)b
Colorectal perforation2/922.2 (2.8–60.0)
Acute appendicitis7/779.1 (3.7–17.8)a
Gastric cancer2/229.1 (1.1–29.2)
Colorectal cancer (elective surgery)6/837.2 (2.7–15.1)
Small bowel obstruction2/287.1 (0.9–23.5)
Acute cholecystitis2/414.9 (0.6–16.5)
Strangulated hernia (femoral or inguinal)0/160 (0–20.6)
Gastrointestinal perforation0/70 (0–41.0)
Hernia (elective surgery; femoral or inguinal)0/1330 (0–2.7)a,b
Gallstone0/450 (0–7.9)
Others2/375.4 (0.7–18.2)
  1. DVT deep venous thrombosis, PE pulmonary embolism, CI confidence interval
  2. Sixteen patients were excluded from the study (patients who already had PE or DVT on admission, or those who underwent a second operation during the hospital stay)
  3. Perforated colorectal cancer cases were included in “colorectal perforation”
  4. aAcute appendicitis vs hernia (elective surgery), p = 0.049
  5. bHepatic cancer, pancreatic cancer vs hernia (elective surgery), p = 0.003
  6. No statistically significant differences were seen among other categories (Fisher test, Bonferroni post hoc test)
  7. 95% confidence intervals were calculated with the Clopper-Pearson method
