IntroductionWith the development and improvement of laparoscopic surgery, procedures have become common. However, post-operative complications occur when patients are released from hospital. These complications increase patients’ morbidity and mortality. They also lead to re-hospitalization, an extended recovery period, and an increase in the cost of treatment.AimTo evaluate and determine the prognostic properties of C-reactive protein in the early diagnosis of postoperative complications after a laparoscopic colon resection.Material and methodsThe prospective study included patients who underwent laparoscopic colorectal surgery in 2010–2014. The patients were divided into two groups – uncomplicated ones and those with complications. C-reactive protein concentrations in their blood serum were measured on the 2nd, 4th and 6th day after surgery. Logistic regression analysis was used to evaluate the relation between C-reactive protein values measured on the 2nd, 4th and 6th postoperative day and related complications. Receiver operating characteristic curves were used to determine the sensitivity and specificity of each C-reactive protein value measured on the 2nd, 4th and 6th postoperative day.ResultsOne hundred and six patients were included in the trial; 14 of them had complications. On the second day, a C-reactive protein cut-off value of 88.6 mmol/l provided the highest sensitivity and specificity for predicting evolving complications, being 71.4% and 84.8% respectively (p = 0.003). The significant predictive cut-off value decreases and becomes more sensitive and specific each post-operative day.ConclusionsIt is possible to detect developing post-operative complications early on by monitoring C-reactive protein concentration levels in the blood serum on the 2nd, 4th, and 6th post-operative days.
Background and objectives: Microwave thermal ablation (MWT) is one of the treatment options for kidney cancer. However, for patients over 70 years old the safety and oncological efficacy of this treatment is still controversial. The goal of this study was to compare MWT with open partial nephrectomy (OPN) and to find out whether MWT is preferable in maintaining patient renal function and reducing the risk of postoperative complications. Materials and Methods: Depending on the treatment choice, all patients were divided into two groups: an MWT group and an open kidney resection (OPN) group. Data have been retrospectively collected for 7 years, starting with January 2012 up to January 2019. A total number of 33 patients with exophytic, single small renal masses were treated with either OPN (n = 18) or MWT (n = 15). All patients had histologically proven T1 kidney cancer. MWT was performed for patients who refused to have OPN or in those cases where the collecting system, renal calyx, and great vessels were free from tumor margins of more than 1 cm. Results: In the MWT group a median (IQR) patients’ age was 75 years (71–79) years, in the OPN group—71.5 (70–75) years, p = 0.005. A median (IQR) Charleston comorbidity index in the MWT group was 7.5 (5–10) and in the same way in the OPN group it was 5.22 (5–6), p = 0.005. A median (IQR) estimated glomerular filtration rate (eGFR) before surgery was higher in the MWT group 59.9 (49.5–73.8) mL/min/1.73 m2 vs. 46.2 (42.7–65.8) mL/min/1.73 m2 in the OPN group, p = 0.12. Three days following the surgery a median (IQR) eGFR was 56.45 (46.6–71.9) in MWT group mL/min/1.73 m2 vs. 43.45 (38.3–65) mL/min/1.73 m2) in the OPN group, p = 0.30. A median (IQR) of primary hemoglobin level was lower in the MWT group compared with the OPN group (134.5 (124–140) g/L vs. 125 (108–138) g/L), p = 0.41. However, after the surgery a median (IQR) lower hemoglobin level was detected in the OPN group (123.5 (111–134) g/L vs. 126 (112–135)), p = 0.53. The median (IQR) duration of the procedure in MWT group was shorter compared with the OPN group (26 (25–30) min vs. 67.5 (55–90) min), p < 0.0001. A median (IQR) hospitalization time was shorter in MWT group (3 (2–3) days vs. 89 (7–11.5) days), p < 0.0001. Pain by the visual analogue scale (VAS) scale the first day after surgery was significantly lower—median (IQR) in the MWT group was 2 (1–3) vs. 4 (3–6)), p = 0.008. Treatment failure rate was numerically higher in MWT (1/15 vs. 0/18, p = 0.56). Conclusions: Pain level on the next day after surgery, mean number of hospitalization and operation time were significantly lower in the MWT group than in the OPN group. The blood loss estimated glomerular filtration rate and oncologic data between the two groups was not statistically significant.
Nephrocutaneous fistula is a very rare complication of renal surgery. It may be associated with renal tumors, nonfunctional kidneys, staghorn calculi, renal trauma or chronic urinary tract infections. Because of widely used imaging
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
