Introduction. The purpose of this study was to evaluate the role of renal cryoablation in patients with solitary kidneys with the goals of tumor destruction and maximal renal parenchymal preservation.Methods. Eleven patients with single tumors were treated with cryoablation, of which 10 patients had solitary kidneys and 1 had a nonfunctioning contralateral kidney. All procedures were performed via an open extraperitoneal approach; ten tumors were treated with in-situ cryoablation and 1 tumor was treated with cryo-assisted partial nephrectomy.Results. Cryoablation was successfully performed without any preoperative complications. Mean patient age was 62.4 years (range 49–79), tumor location included: 6 (upper pole), 2 (mid-kidney), 3 (lower pole). The mean and median tumor size was 2.6 cm and 2.8 cm (range 1.2–4.3 cm), mean operative time 205 minutes (range 180–270 minutes), blood loss 98.5 ml (range 40–250 ml), and hospitalization 4.6 days (range 3–8 days). Creatinine values included: preoperative 1.43 mg/dL (range 1.2–1.9), postoperative 1.67 mg/dL (range 1.5–2.5), and nadir 1.57 mg/dL (range 1.3–2.1). All patients were followed postoperatively with magnetic resonance imaging for surveillance. At a median follow-up of 43 months, 9 patients had no evidence of recurrence, 1 patient has an enhancing indeterminate area, and 1 patient was lost to follow-up.Conclusion. Intermediate-term results suggest that renal cryoablation offers a feasible alternative for patients that require a maximal nephron-sparing effort with preservation of renal function and minimal risk of tumor recurrence.

Abstract Open partial nephrectomy, or nephron-sparing surgery (NSS), is now considered as the standard for small renal tumors treatment. The oncologic efficacy and safety of NSS for the treatment of stage-T1a renal tumors have been repeatedly demonstrated to be equivalent to radical nephrectomy. A 66-year-old gentleman chronic smoker was incidentally found to have a small mid pole lesion in the left kidney on routine ultrasound scan, CT finding was 2x2 cm mid pole tumor, no involvement or metastasis, the patient given the option of partial nephrectomy. In surgery, the left kidney was explored, and the tumor mass was seen to occupy the mid pole. The mid pole branch of the renal artery was clamped after cooling the kidney with ice slush following 300cc of 20% mannitol infusion. In-situ nephron-sparing left nephrectomy was done with a margin of 1cm minor upper calyceal injury repaired. The patient was discharged five days postoperative. Gross examination of the specimen revealed a wedge biopsy of the mid pole with attached perinephric fat with swelling part at the outer surface, pushing the capsule. Microscopic sections show a well-defined tumor mass in the renal parenchyma, surrounded by a fibrous capsule, composed of a multilocular cystic area lined by malignant cells. NSS initially was reserved for patients with solitary kidneys, tumors, and those with significant comorbidities predisposing to future renal failure; indications have expanded recently to allow elective partial nephrectomy in the setting of a normal contralateral kidney.

The role of self-expandable metallic stents is gradually evolving for a diverse group of benign and malignant gastrointestinal tract problems, with luminal obstruction being by far the most common. Although its role in refractory variceal bleeding is well established, it has rarely been tried for tumor-related bleeding, with only a few case reports in this regard. We share our experience of successfully controlling esophageal tumor–related bleeding with the use of a fully covered self-expandable metallic stent. A 58-year-old woman with irresectable distal esophageal cancer, presented with hematemesis. Esophago-gastro-duodenoscopy revealed an obstructing esophageal tumor with diffuse oozing of blood. This was unamenable to local injection of adrenaline and hemospray; therefore, a temporary self-expandable metallic stent was parked to create a tamponade effect. This successfully stopped bleeding and the patient remained asymptomatic till discharge. However, she was lost to follow-up, and therefore, the stent was removed after a period of 5 months instead of 2 weeks.

Abstract BACKGROUND There is lack of information on the role of excitatory and inhibitory neurotransmitters in the development of seizures in patients with lower grade gliomas. Increase of glutamate and downregulation of GABA have been suggested in preclinical models and human surgical samples to be associated with brain tumor-related epilepsy. MATERIAL AND METHODS We prospectively investigated with the use of magnetic resonance spectroscopy (MRS) the differences in the ratio of metabolites (glutamate/GABA, glutamate/creatine and GABA/creatine) in the peritumoral areas between patients with or without seizures in a series of lower grade gliomas. Tumors were classified according to WHO Classification of 2016 as follows:11 grade II IDH mutated and 1p/19q codeleted; 3 grade III IDH mutated and 1p/19q codeleted; 6 grade II IDH mutated and 1p/19q intact; 1 grade III IDH mutated and 1p/19q intact; 1 grade II IDH wild-type. Patients received surgery alone or followed by temozolomide chemotherapy according to the presence of risk factors. RESULTS At baseline evaluation, maximum glutamate/GABA values were significantly higher (p=0.023) in the peritumoral area of patients with seizures (1.008 ± 0.368) with respect to those without seizures (0.691 ± 0.170). No other metabolites ratio showed significant differences between the two groups. Similar results were obtained when analyzing the metabolites ratio in the examinations during the follow-up. In the cohort of patients with seizures (n.14) variations of metabolite ratios were not associated with tumor location, 1p/19q codeletion, use of AEDs, concomitant chemotherapy or seizure characteristics (type, duration, frequency). CONCLUSIONS The study is ongoing with the aim of analyzing further the correlations between ratio of metabolites and status of the tumor (stable vs progressive).

Purpose. Assessing the role of breast MRI compared to galactography in patients with unilateral bloody or serous-bloody nipple discharge.Materials and Methods. Retrospective study including 53 unilateral discharge patients who performed galactography and MRI. We evaluated the capability of both techniques in identifying pathology and distinguishing between nonmalignant and malignant lesions. Lesions BIRADS 1/2 underwent follow-up, while the histological examination after surgery has been the gold standard to assess pathology in lesions BIRADS 3/4/5. The ROC analysis was used to test diagnostic MRI and galactography ability.Results. After surgery and follow-up, 8 patients had no disease (15%), 23 papilloma (43%), 11 papillomatosis (21%), 5 ductal cancer in situ (10%), and 6 papillary carcinoma (11%) diagnoses. Both techniques presented 100% specificity; MRI sensitivity was 98% versus 49% of galactography. Considering MRI, we found a statistical association between mass enhancement and papilloma (P<0.001; AUC 0.957; CI 0.888–1.025), ductal enhancement and papillomatosis (P<0.001; AUC 0.790; CI 0.623–0.958), segmental enhancement and ductal cancer in situ (P=0.007; AUC 0.750; CI 0.429–1.071), and linear enhancement and papillary cancer (P=0.011).Conclusions. MRI is a valid tool to detect ductal pathologies in patients with suspicious bloody or serous-bloody discharge showing higher sensitivity and specificity compared to galactography.

The role of in situ decompression in patients with severe ulnar nerve compression is still controversial. Thirty patients with severe ulnar nerve compression confirmed clinically and electrophysiologically underwent simple decompression. The mean age of the patients was 58 (range 26–87) years. Through incisions ≤4 cm the nerves were fully visualized and decompressed. Outcome was measured prospectively using Modified Bishop’s score (BS), grip and pinch strengths and two-point discrimination (2PD). Significant improvement in power (p = 0.01) and pinch grip (p = 0.001) was noted at 1 year. The grip strength continued to improve up to 1 year. According to the BS, 24 patients (80%) had good to excellent results at 1 year. Minimally invasive in situ decompression is technically simple, safe and gives good results in patients with severe nerve compression. The BS and 2PD were more reliable than grip strength in assessing these patients at follow-up.

e16139 Background: To present our experience with elective, open, nephron-sparing surgery for renal masses in a contemporary, consecutive series. Methods: In this retrospective study, records of all patients who underwent elective nephron-sparing surgery (E-NSS) between March 1997 and December 2007 at our institution were reviewed. The preoperative workup included laboratory analysis, renal ultrasonography and abdominal computed tomography. The histological findings, complications, and oncologic outcome were studied. Results: A total of 231 E-NSS were performed in 223 patients (82 females,141males; mean age 64 years). 62 “hot ischemia” procedures and 169 “cold ischemia”. The mean tumor size was 4.6 cm (1.1–12cm). 52 patients presented renal masses > 4cm. Renal cell carcinoma was present in 177 patients (76.6%), benign renal masses were diagnosed in in 54 pazienti (23.3%): angiomyolipoma (35%), oncocytoma (40%), complicated cyst (25%). Worthy of note among these 54 patients, pre-operative diagnosis was present in 12 patients. Moreover, 17 benign lesions (31%) were > 4 cm. Complication rate was 5.3% (12 pts): splenectomy (2.2%), nephrectomy because of postoperative bleeding (0.8%), urinary fistulas (0.8%). After a median follow-up of 84 months (range 5 to 120), no patient had developed local recurrence, 19 (8.9%) died for other causes, 2 (0.9%) died for other tumor. Conclusions: The results of this contemporary, monocenter experience underline the role of open, elective, nephron-sparing surgery for patients with renal masses, confirming good results even for renal masses > 4cm. These conclusions are particularly important considering that benign histologic findings were present in almost one forth of patients. No significant financial relationships to disclose.

Abstract Introduction Ureteric stents are routinely used in ureteric obstruction, however, have considerable morbidity with major complications, such as encrustation, obstruction, urosepsis, and renal failure if left in situ for longer than six months. Despite an electronic stent register, there are still multiple emergency admissions of complications from forgotten stents, as well as those presenting with significant stent symptoms. Often stents are inserted as an emergency procedure with minimal information given on their discharge summary. A discharge template was therefore introduced that could also serve as a patient information leaflet to help minimise the incidence of forgotten stents. Method A discharge template was designed based off the trust-endorsed and British Association of Urological Surgeons (BAUS) patient leaflet and distributed amongst the juniors. A total of 28 patients were interviewed via telephone questionnaires – 21 randomly selected pre-intervention and 7 post-intervention from a one-month scale either side of the intervention. The template included: information on stents, common stent symptoms, indications to seek healthcare advice, and contact details to use in the event they are lost to follow-up. Results Patients aware that stents should be changed within six months went from 52% to 100%. Awareness of stent symptoms and red-flag symptoms went from 52% to 91%, and 57% to 100% respectively. Those who felt they had sufficient information on the discharge letter to understand their stent increased from 52 to 89%. Conclusions Significant improvement in patient understanding of stents and therefore hopefully in appropriate health-seeking behaviour, patient rapport, safety, and improvement in stents removed within target.

A descriptive analysis was performed in order to evaluate the completeness of follow-up and to explore the occurrence of malignancy in the Italian section of the European Prospective Investigation into Cancer and Nutrition (EPIC-Italy) at the first follow-up for cancer incidence. The EPIC-Italy cohort consisted of 47,749 subjects, aged 35-65 years, who voluntarily accepted to participate in the project from 1992-1997. Tabulations of the enrolled subjects are presented by sex, age groups, population at risk and person-years as calculated at the first follow-up in 1998; alive, lost to follow-up and dead subjects were tabulated by sex and centers. Cancer occurrence is described by quality indexes of data collected and the lapse of time between the date of recruitment and date of diagnosis. External comparisons for each center and pooled data were carried out by calculation of standard incidence ratios (SIRs) using the rates of the population-based cancer registries covering the areas of EPIC Italian centers. Similarly, an internal comparison was also performed using as the reference population the EPIC-Italy center with the lowest crude cancer incidence rates. A total of 148,968 person-years (43,568 men and 105,400 women) was calculated as the denominator; the percentages of lost to follow-up were 1.34% for men and 0.9% for women. We found 781 malignancies (216 in males and 565 in females), 17 in situ breast cancers and 8 in situ cervical cancers. In men 65 malignant cases (30.1%) and in women 186 malignancies (32.9%) occurred in the first year following enrollment. The proportion of microscopically verified cancers was 93.1%. In pooled data for men, statistically significant SIRs of less than 1 were calculated for all cancer sites combined (SIR = 0.81), lung (SIR = 0.49) and bladder (SIR = 0.62), whereas statistically significant excesses of observed cases were found for melanoma and cancers of ill-defined sites within respiratory system and intrathoracic organs (ICD-0-2 = C39). In pooled data for women, none of the SIRs were statistically significant. For men, SIRs disaggregated by center showed statistically significant excesses of cases only in Florence for the thyroid (SIR = 5.01). For women, statistically significant excesses of observed cases were computed in Florence and Varese for breast cancer (SIRs, 1.36 and 1.27, respectively), Florence for uterine cancer NOS (SIR = 20.3) and Varese for kidney (SIR 2.24). Internal comparisons showed some evidence of an excess of cases in northern compared to southern centers. In conclusion, after an average follow-up of 3 years, nearly 99% of the enrolled individuals were traced and checked for their vital status. Cancer occurrence in women was not far from that expected in comparison to the local general population, whereas in men significantly fewer cases than expected were observed. This preliminary descriptive analysis will be used as a starting point for monitoring the validity of EPIC-Italy over time.
