Abstract

To investigate the incidence of systemic inflammatory response syndrome (SIRS) on emergency department admission and the prognostic significance of SIRS in patients undergoing emergency surgery. This is a retrospective study of 889 adults who were admitted as emergency cases and were operated on within 24 hours of admission. Data on patient demography, clinical information including comorbidities, categories of surgery, American Society of Anesthesiologists physical status, SIRS score, postoperative outcomes including duration of mechanical ventilation, intensive care unit (ICU) and hospital lengths of stay, and mortality were collected. SIRS occurred in 43% of the patients and was associated with a significantly worse outcome in terms of duration of ventilator use (10.5 ± 15.4 vs. 3.5 ± 4.4 days, p < 0.001), ICU stay (11.2 ± 13.6 vs. 5.0 ± 5.4 days, p < 0.001), hospital length of stay (19.4 ± 22.4 vs. 7.1 ± 7.6 days, p < 0.001) and mortality (12.7% vs. 0.4%, p < 0.001). After adjusting for covariates (including age, gender, American Society of Anesthesiologists physical status, comorbid conditions, and surgery categories), SIRS was independently associated with higher mortality (adjusted odd ratio, 21.5, 95% confidence interval (CI), 4.9–93.2), longer ventilator duration (adjusted coefficient, 7.8, 95% CI, 3.2–12.5), longer ICU stay (adjusted coefficient, 6.2, 95% CI, 2.6–9.8) and longer hospital stay (adjusted coefficient, 9.7, 95% CI, 7.5–11.9). The presence of SIRS at admission in patients receiving emergency surgery predicted worse outcomes and higher mortality rates.

Abstract

Among several minimally invasive adrenalectomy techniques, lateral transperitoneal adrenalectomy (LTA) is the procedure of choice for benign adrenal tumors, however, posterior retroperitoneoscopic adrenalectomy (PRA) is an alternative that is increasing in popularity. This study compared the outcomes of these two approaches. Since a single surgeon started adrenalectomy, LTA had been performed exclusively until PRA was adopted and became the standard treatment. Therefore, the consecutive patients were allocated into two groups according to the date of surgery: the first group received LTA and the second group received PRA. LTA was performed in 29 patients and PRA in 19 patients. There was no difference in sex, age, body mass index, clinical diagnosis, and tumor size between the LTA and the PRA group. The PRA group showed less blood loss (117.0 mL vs. 58.5 mL, p = 0.035) and tended to have a shorter operating time (92.2 minutes vs. 78.1 minutes, p = 0.054) and less pain score on postoperative Day 1 (3.8 vs. 3.0, p = 0.095) and Day 2 (3.2 vs. 2.5, p = 0.051). The mean operation time was significantly shorter for patients in the PRA group undergoing right adrenalectomy (109.2 minutes vs. 80.5 minutes, p = 0.009), but those undergoing left adrenalectomy had a similar operating time to the LTA group (83.2 minutes vs. 74.8 minutes, p = 0.380). PRA is a good alternative operative technique for an endocrine surgeon who is experienced in the transperitoneal approach.
