Enhanced recovery after surgery and mini-invasive approaches in rectal cancer surgery - short-term outcomes.

INTRODUCTION: The aim of this study was to evaluate short-term outcomes of patients undergoing mini-invasive rectal resection within an ERAS (enhanced recovery after surgery) protocol. METHODS: A prospectively managed database of patients undergoing rectal operations performed at our department between January 2015 and April 2020 was retrospectively analyzed. An ERAS protocol was implemented into clinical practice at our department in April 2016 and mini-invasive rectal procedures in May 2016. The ERAS group consisted of all patients who underwent mini-invasive rectal resections or amputations within the ERAS protocol. The control group consisted of patients who underwent open procedures and received standard perioperative care. The extracted data included basic patient characteristics, surgical data, postoperative recovery parameters, 30-day morbidity, length of postoperative stay and 30-day rehospitalization. RESULTS: A total of 110 patients were included in the study: 67 patients in the ERAS group and 43 in the control group. Within the ERAS group 47 patients underwent robotic procedures and 20 had laparoscopic procedures. Patients in the ERAS group had significantly better clinical and laboratory recovery parameters except for postoperative nausea and vomiting. A significantly lower incidence of paralytic ileus (20.9% vs. 3%) and a shorter length of postoperative stay (13 days vs. 9 days) was found in the ERAS group. The rehospitalization rate and 30-day morbidity were not different between the ERAS and control group. CONCLUSIONS: Implementation of the ERAS protocol in combination with mini-invasive approaches leads to better short-term postoperative outcomes after rectal surgery.

[The role of rotational thromboelastometry (ROTEM) in the perioperative period in a warfarinized patient (case report)]. / Význam rotacnej tromboelastometrie (ROTEM) v perioperacnom období u warfarinizovaného pacienta.

UNLABELLED: Warfarin overdose with unmeasurable values of the prothrombin time (PT-INR) is a significant problem in the preoperative preparation of the patient for acute invasive surgery. In contrast to conventional blood clotting assays, rotational thromboelastometry (ROTEM) evaluates the coagulation profile of the whole blood and provides a more complex view of the coagulation status of the patient. Thromboelastometry results are available within about 10 minutes and help us to provide targeted "bedside" therapy of coagulopathy in a bleeding patient. In our case report we describe a case of a patient with warfarin overdose and unmeasurable PT-INR values. The patient was indicated for urgent gastroscopy because of haematemesis and abdominal surgery because of ileus. Haematemesis was stopped by ROTEM targeted treatment of coagulopathy and the operation was performed without bleeding complications with normal ROTEM despite the prolongation of PT-INR to 1.8. Finally, we would like to say that ROTEM method can be used for rapid management of warfarin-induced coagulopathy and that surgery may be performed safely without any correction of PT-INR in case of normal ROTEM. KEY WORDS: prothrombin time - bleeding - surgery thromboelastometry (ROTEM) warfarin.

The use of broad-range bacterial PCR in the diagnosis of infectious diseases: a prospective cohort study.

OBJECTIVES: Broad-range PCR has the potential to detect virtually any bacterial species via amplification and nucleotide sequencing of a DNA region common to all bacteria. We aimed to evaluate its usefulness and clinical relevance when applied to a wide variety of primary sterile materials. METHODS: A prospective study including 1370 samples (75 heart valves, 151 joint tissue samples, 230 joint aspirates, 848 whole blood samples and 66 culture-negative cerebrospinal fluid samples) were studied by using a commercial PCR system for detecting 16S rDNA (Molzym). The PCR results were compared with culture and were considered to provide added diagnostic value only if the PCR approach revealed new pathogens that were missed by culture. RESULTS: The added value of PCR was evident in 173 of 555 PCR-positive samples (0.126; 0.109-0.144 (proportion from all tested samples; 95% confidence interval)), most frequently in examinations of heart valves (0.56; 0.448-0.672) and joint tissue samples (0.219; 0.153-0.284). In contrast, the lowest rate of PCR with added value was noted for blood samples, regardless of the patient cohort they had been drawn from (nononcologic patients from intensive care: 0.065; 0.043-0.087, haematooncologic children: 0.048; 0.027-0.070). Moreover, PCR missed up to 7.1% of blood culture findings (0.071; 0.048-0.095) regarded as clinically relevant, which was the second highest failure rate after joint tissue samples (0.099; 0.052-0.147). CONCLUSIONS: Broad-range PCR substantially increases detection rate of pathogens, especially from heart valves and joint samples. However, a concurrent risk of false-negative PCR results justifies the need for parallel culture.
