RESUMEN
OBJECTIVE: This study investigates the diagnostic power of CT scan combined with exploratory laparoscopy (EXL) at identifying large bowel involvement in patients with stage IIIC-IV primary Epithelial Ovarian Cancer (EOC) by comparing with the macroscopic surgical findings at laparotomy. METHODS: All patients with FIGO Stage IIIC-IV EOC who had Visceral Peritoneal Debulking (VPD) were included in the study. Results of CT scan, EXL and laparotomy (LPT) with regards to the bowel involvement were prospectively recorded in an ad hoc study form. Setting LPT findings as the gold standard, positive and negative predictive value (PPV/NPV), sensitivity, specificity and accuracy of CT and EXL were calculated. In addition, the diagnostic power of the combination CT scan + EXL was investigated. RESULTS: Ninety-four out of 177 patients (53.2%) had a bowel resection during VPD. CT-scan alone had sensitivity, specificity, PPV, NPV and accuracy of 56.7%, 72.4%, 70.8%, 58.5% and 63.8% respectively. EXL alone 84.4%, 93.8%, 93.8%, 84.3%, 88.8%. CT combined with EXL detected bowel involvement with a sensitivity, specificity, PPV, NPV and accuracy of 87.5%, 70.4%, 77.8%, 82.6% and 79.6% and respectively. The combined tests showed a statistically significant improvement vs. CT scan alone (pâ¯<â¯0001) in sensitivity, NPV and accuracy, with non-significant difference in specificity and PPV. CONCLUSIONS: CT-scan alone shows a limited diagnostic power at detecting large bowel involvement in patients with stage IIIC-IV EOC. The combination of CT scan with EXL increases the diagnostic power and enables to appropriately plan the bowel resection and consent the patients.

OBJECTIVES: Acute kidney injury (AKI) is a common complication of cardiac surgery developing in 25-35% cases. Recently, neutrophil gelatinase-associated lipocalin (NGAL) was shown to predict AKI development earlier than serum creatinine. Some studies demonstrated the predictive role of post-operative serum uric acid (SUA) as an early marker of AKI. We aimed to study the role of serum and urine NGAL as well as SUA to predict progression of AKI. DESIGN AND METHODS: This is a prospective observational study of patients undergoing cardiac surgery. Blood and urine samples for measurement of uric acid, serum and urine NGAL levels were collected prior to cardiac surgery (0 h), and in the time course at 2nd and 24th hours after surgery. Patients who developed AKI were divided into two subgroups as progressing and non-progressing AKI. RESULTS: Sixty patients (42 males, 18 females) were included. After cardiac surgery, 40 patients developed AKI, 20 of whom non-progressing AKI, and 20 progressing AKI. All of the markers significantly increased in AKI patients. A receiver operator characteristics (ROC) curve analysis showed higher predictive ability of SUA for progressing AKI compared with serum and urine NGAL. When compared markers obtained at the second hour after surgery, UA had significantly large AUC than NGAL to predict AKI developed at 24 and 48 h, particularly in patients, who require renal replacement therapy (RRT). CONCLUSION: Uric acid seems to predict the progression of AKI and RRT requirement in patients underwent cardiac surgery better than NGAL.

OBJECTIVE: To assess the morbidity associate with rectosigmoid resection (RSR) in patients with stage IIIC-IV ovarian cancer (OC) undergone primary debulking surgery (PDS) vs. interval debulking surgery (IDS) after neoadjuvant chemotherapy (NACT). METHODS: From the Oxford Advanced OC database, we retrieved all patients who underwent surgery between January 2009 and July 2016 and included all patients who underwent RSR. We compared the rates of overall related and not-related morbidity and bowel diversion in patients undergone RSR during PDS vs. IDS. RESULTS: Three hundred and seventy-one patients underwent surgery: 126 in PDS group and 245 in IDS group. Fifty-two patients in the PDS group (41.3%) and 65 patients in IDS group (26.5%) underwent RSR (p<0.001). Overall not related morbidity rate was 37.5% and 28.6%, p=0.625. Bowel specific complications affected 16.3% vs. 11.1% of the patients (p=0.577). IDS group had higher rate of bowel diversion compared with PDS (46.0% vs. 26.5%, p=0.048). CONCLUSION: NACT was associated to an overall reduced rate of RSR compared to IDS. No differences in overall related and not-related complications in patients requiring RSR were seen between the 2 groups. Patients in the IDS group had a significantly higher rate of bowel diversion.

RESUMEN
OBJECTIVES: To assess the impact of multiple bowel resections on postoperative outcomes in stage IIIC-IV ovarian cancer (OC). METHODS: From the Oxford OC database we retrieved consecutive patients who underwent bowel resection between January 2009 and November 2017. Patients were divided into two groups: single bowel resection (SBR) and MBR (≥2 bowel resections). The following outcomes were compared between the two groups: 30-day related and not related morbidity to bowel surgery, bowel diversion rate and time to start/restart adjuvant chemotherapy. RESULTS: Thirty-five patients were in the MBR and 146 in the SBR group. The 30-day overall surgical-related complication and bowel specific complications rate was higher in MBR group than SBR group (54.3% vs. 23.9%, pâ¯<â¯0.001) and (25.7% vs. 10.5%, pâ¯=â¯0.035), respectively. The rate of bowel diversion was 97.7% in MBR vs. 26.7% in the SBR group (pâ¯=â¯0.021). Trend analysis showed a significant reduction in the rate of MBR after the introduction of NACT (p- for trend <0.001). CONCLUSIONS: Our data show that MBR during OC surgery is associated with a higher rate of overall and bowel specific complication compared to SBR. The introduction of NACT is associated with a reduced rate of MBR.

We investigated the effectiveness of shear wave elastography (SWE) in patients with lower extremity superficial venous insufficiency (VI). A total of 138 symptomatic patients, 51 asymptomatic volunteers, and a total of 359 lower extremities (257 symptomatic, 102 asymptomatic) were examined. All participants underwent Doppler ultrasound (US) evaluation to determine VI and SWE measurements performed by manually drawing vein wall and perivenous tissue with free region of interest at the great saphenous vein (GSV) and small saphenous vein (SSV). The GSV, SSV diameter, VI, and volume flow of reflux were compared with the SWE values. The SWE values of the symptomatic group for GSV and SSV were significantly higher than those of the asymptomatic control group regardless of whether VI was detected by Doppler US (P < 0.001). There was a statistically significant increase in SWE values for the symptomatic group who were diagnosed as having reflux in GSV and SSV (P < 0.001). A significant positive correlation between increased GSV, SSV diameter, and SWE values was seen (P < 0.001). Venous insufficiency can be diagnosed with a 84.7% sensitivity and 84.2% specificity when 2655 m/s was designated as cutoff value, and with a 85.4% sensitivity and 84.2% specificity when 22,350 kPa was designated as the cutoff value in GSV. Venous insufficiency can be diagnosed with a 84.3% sensitivity and 82.4% specificity when 2845 m/s was designated as cutoff value, and with a 85.7% sensitivity and 84.4% specificity when 27,100 kPa was designated as the cutoff value in SSV. Shear wave elastography may be used effectively in addition to conventional Doppler US examination in diagnosing and following VI.

OBJECTIVE:: Risk assessment for operative mortality is mandatory for all cardiac operations. For some operation types such as aortic valve repair, EuroSCORE II overestimates the mortality rate and a new scoring system (German AV score) has been developed for a more accurate assessment of operative risk. In this study, we aimed to validate German Aortic Valve Score in our clinic in patients undergoing isolated aortic valve replacement. METHODS:: A total of 35 patients who underwent isolated open aortic valve replacement between 2010 and 2013 were included. Patients with concomitant procedures and transcatheter aortic valve implantation were excluded. Patients' data were collected and analyzed retrospectively. Patients' risk scores EuroSCORE II were calculated online according to criteria described by EuroSCORE taskforce, Aortic Valve Scores were also calculated. RESULTS:: The mean age of patients was 61.14±13.25 years (range 29-80 years). The number of female patients was 14 (40%) and body mass index of 25 (71.43%) patients was in range of 22-35. Mean German Aortic Valve Score was 1.05±0.96 (min: 0 max: 4.98) and mean EuroSCORE was 2.30±2.60 (min: 0.62, max: 2.30). The Aortic Valve Score scale showed better discriminative capacity (AUC 0.647, 95% CI 0.439-0.854). The goodness of fit was x2HL=16.63; P=0.436). EuroSCORE II scale had shown less discriminative capacity (AUC 0.397, 95% CI 0.200-0.597). The goodness of fit was good for both scales. The goodness of fit was x2HL=30.10; P=0.610. CONCLUSION:: In conclusion, German AV score applies to our population with high predictive accuracy and goodness of fit.

INTRODUCTION: Chronic post-traumatic arteriovenous fistula (AVF) is a late complication of vascular injury and can be presented with symptoms of congestive heart failure, venous hypertension and distal ischaemia. We present an unusual case of chronic leg swelling in adult caused by post-traumatic AVF. CASE PRESENTATION: A 52 year old white-male patient complained of palpitation, pain and swollen right leg. Arterial pulses distally from the groin were present. His medical history revealed him to have sustained gunshot injury of the left thigh 5 years before. Angiography showed a large AVF between superficial femoral artery and femoral vein. The patient underwent surgical repair of AVF with ligation of AVF between superficial femoral artery under spinal anaesthesia. Completion angiography confirmed AVF exclusion. Leg swelling healed within a month. CONCLUSION: Post-traumatic fistula should be obliterated as soon as possible. Untreated fistula results in complications including renin-mediated hypertension and high-output heart failure, venous and/or arterial insufficiency.
