Evaluation of Subclinical Fluid Overload Using Lung Ultrasound and Estimated Plasma Volume in the Postoperative Period Following Kidney Transplantation.

AIM: B-lines count measured with lung ultrasound (LUS) quantifies extravascular lung water and is validated in the setting of acute cardiac failure or chronic dialysis. Patients are often kept in moderately overhydrated states during the early postoperative period following kidney transplantation (KT). We described congestion changes during the early postoperative period following KT and the feasibility of LUS in this setting. METHODS: LUS (28 scanning-points method) and inferior vena cava (IVC) measurements were routinely performed in 36 patients after KT. Estimated plasma volume (ePV) was calculated from hemoglobin and hematocrit levels. RESULTS: No patient had >15 B-lines during the hospital stay. B-lines slightly increased until Day 4 after KT (Day 1, 1.7 ± 1.7; Day 4, 2.5 ± 2.5) and decreased up to Day 10 (1.4 ± 2.2; P vs Day 4 <.05). More B-lines were observed in patients aged older than 60 (P = .01 at Day 4) whereas IVC diameter and ePV were similar. In patients older than 60, B-lines had weak correlation with body weight variation (r = 0.64; P < .05), IVC diameters (r = 0.59 at Day 4 and r = 0.58 at Day 10; P < .05) but a strong correlation with ePV (r = 0.93 at Day 14; P < .05). B-line changes from Day 1 to Day 10 correlated with IVC diameter changes (r = 0.62; P < .05). CONCLUSION: LUS identifies subtle congestion changes during the early postoperative period following KT. The hyperhydration strategy usually followed during this period does not result in overt pulmonary congestion as assessed by LUS, even in older recipients.

Elevated serum uric acid concentration at discharge confers additive prognostic value in elderly patients with acute heart failure.

BACKGROUND AND AIMS: Elevated serum uric acid (sUA) concentrations have been associated with worse prognosis in heart failure (HF) but little is known about elderly patients. We aimed to assess long-term additive prognostic value of sUA in elderly patients hospitalized for HF. METHODS AND RESULTS: Clinical and echocardiographic characteristics of 310 consecutive elderly patients hospitalized for HF were collected. During index period, 206 had sUA concentrations available, which were obtained within 24 h prior to discharge; 10 patients were lost to follow-up, leaving 196 patients available. Patients had a median age of 77 (IQR 69-83) years, and were mostly male (64.5%). sUA ranges for tertiles I-III were: 1.5-6.1, 6.2-8.3, and 8.4-18.9 mg/dl, respectively. During a median follow-up of 27 months (IQR 10.5-39.5), 122 combined events occurred (87 deaths and 73 HF rehospitalizations). Four-year event-free survival for the combined endpoint was 46 ± 7% for tertile I, 34 ± 7% for tertile II, and 21 ± 5% for tertile III (P = 0.001). By multivariable Cox backward analysis, sUA was retained as a significant predictor. Compared with the lowest sUA tertile, tertile III showed a strong association with outcome, also after adjustment for other predictors (HR 1.84, 95% CI 1.16-2.93; P = 0.01). Importantly, addition of sUA to the other significant predictors of outcome resulted in improved risk classification (net reclassification improvement 0.19, P = 0.017). CONCLUSIONS: High sUA at discharge is a strong predictor of adverse outcome in elderly hospitalized for HF, and it significantly improves risk classification. Measuring sUA can be a simple and useful tool to identify high-risk elderly hospitalized for HF.

Survival following salvage abdominoperineal resection for persistent and recurrent squamous cell carcinoma of the anus: do these disease categories affect survival?

AIM: This study aimed to investigate the results of salvage abdominoperineal excision (APR) in patients with persistent or recurrent squamous cell carcinoma of the anus (SCCA). METHOD: Patients with anal neoplasia were identified from a prospective database. Patients with invasive SCCA with demonstrated failure of chemoradiation therapy (CRT) who underwent salvage APR for one of three disease categories (persistent, < 6 months post-CRT; early recurrent, 6-24 months post-CRT; late recurrent, > 24 months post-CRT) were included. The primary outcome was overall survival after salvage APR. Tumour size, metastatic lymph nodes (LN), circumferential resection margin positivity (CRM) and neurolymphovascular invasion (NLVI) were correlated with the outcome. RESULTS: Thirty-six patients with a median 3-year overall survival of 46% (median follow-up 24 months) underwent salvage APR due to persistent or recurrent SCCA (14 men, mean age 59 years). Eleven (31%) patients were diagnosed with persistent disease, 17 (47%) with early and 8 (22%) with late recurrence. Two-year overall survival of Stage 0/I/II and III/IV disease was 81.5% and 33.74%, respectively (P = 0.022). Overall disease stage was associated with disease categorization (P = 0.009): patients with persistent disease or early recurrence had a significantly higher disease stage than patients with late recurrence (OR = 20.9 and 17.2). Despite apparently improved survival in patients with late disease recurrence on live table analysis, no significant difference was identified in overall survival when stratified by disease category on log-rank test analysis. CONCLUSION: Persistent and recurrent disease does not show any significant difference in survival, but patients with late recurrence may have a better prognosis.

Open sphincter-preserving surgery of extraperitoneal rectal cancer without primary stoma and Fast Track Protocol.

AIM: Fast track protocol (FTP) showed to improve perioperative care. The study aims to evaluate the impact of the FTP in the open extraperitoneal rectal cancer (ERC) surgical treatment without a primary derivative stoma (DS) and the QoL in patients with or without a secondary DS. PATIENTS AND METHODS: 50 patients affected by ERC were enrolled and operated on with open low anterior resection without a primary DS. They were randomized in two groups: one was treated perioperativelly in the traditional way (group T), the other using a modif ed FTP (group FT). A QoL questionnaire was administered prior to discharge and at 1-month follow-up. RESULTS: Five courses (10%) were complicated by anastomotic leakage: 3 (12%) in the FT group (2 minor and 1 maior) and 2 (8%) in the T group (1 minor and 1 maior) (p=n.s.). All the maiors and one minor were treated with a DS. Patients of the group FTP were considered dischargeable earlier that those of group T (p<0.05). Patients with DS had a significantly lower QoL score (p<0.0001). CONCLUSION: FTP with minor modifications is feasible and safe in the ERC open surgery without using a DS. Better results were obtained without increasing complication rate. A secondary DS impacts detrimentally on QoL.

A comparison of the outcome using Ligasure™ small jaw and clamp-and-tie technique in thyroidectomy: a randomized single center study.

PURPOSE: Hypoparathyroidism and paralysis of the recurrent laryngeal nerve (RLN) still remain the most frequent specific complications of thyroid surgery. This study evaluates the effects of employment of a recently introduced device (LigaSure™ Small Jaw, LSJ), compared to the traditional clamp-and-tie (CT) technique, on the short- and long-term outcome of the patients who underwent thyroidectomy. METHODS: This prospective, randomized study included 190 patients enrolled from October 2011 to July 2013. The numbers of patients in the LSJ group and the CT group were both 95. We studied the following: operative times, intraoperative and postoperative blood losses, intact parathormone (iPTH) and calcium serum levels, and the incidence of RLN paralysis. RESULTS: The two cohorts were homogeneous for age, sex, surgical indication, BMI, ASA score, and estimated thyroid volume. Operation time has been 73.90 ± 23.35 min in group CT and 60.20 ± 22.36 min in group LSJ (p = 0.002). Intraoperative blood losses have been 47 ± 18 ml in group CT and 38 ± 14 in group LSJ (p = 0.002), while postoperative blood losses have been 45 ± 21 ml in group CT and 40 ± 20 in group LSJ (p = 0.105). The mean calcium blood level in group CT has been 8.12, 7.79, and 7.92 mg/dl in the first, second, and third postoperative days, respectively, as well as 8.26, 7.97, and 8.22 mg/dl for group LSJ (p > 0.05). Basal and post-thyroidectomy iPTH levels have been 46.49 and 23.64 pg/ml in group CT (Δ = 49.15 %), as well as 51.06 and 27.73 (Δ = 45.69 %) in group LSJ (p > 0.05). Permanent RLN paralysis was 1.05 % in LSJ group and 0 % in CT group. CONCLUSION: The employment of LSJ reduces in a statistically significant way both operative times and intraoperative blood losses. No significant differences were found as far as postoperative RLN paralysis and hypoparathyroidism.

Mirizzi Syndrome in a patient with an accessory hepatic duct.

Mirizzi syndrome (MS) represents an uncommon clinical condition, being characterized by a narrowing of the common hepatic duct or its erosion by stones impacted in the cystic duct or gallbladder Hartman's pouch. Very uncommonly, MS can be reported in patients with contemporaneous bile duct anomalies. The case is reported of a 76-year-old Caucasian woman with a MS with a cholecystobiliary fistula and a contemporaneous aberrant biliary duct for the right posterior segments.Due to the presence of an anatomical abnormality, an open approach was decided: also during surgery, it was impossible to clarify which part of the biliary tree the accessory duct merged into. After surgery, post-operative course was uneventful: the patient is alive without medical problems (follow-up: 16 months). MS represents a challenge for the surgeon. Contemporaneous presence of biliary abnormalities is anecdotic, increasing the risk of iatrogenic injuries. An open approach may be preferred in these conditions.

Extended criteria liver donation and transplant recipient consent: the European experience.

The organization known as ELPAT (Ethical, Legal and Psychological Aspects of Organ Transplantation) coordinated the distribution of an electronic questionnaire concerning the definition of extended criteria liver donation (ECD) and the implication for informed consent of transplant recipients to European liver transplant centers. Completed questionnaires were received from 30 centers in 13 countries. Twenty-eight centers accepted ECD liver donors. The criteria for defining a liver donor as ECD were: steatosis in 24 centers (85%); age up to 80 years in 23 centers (82%); serum sodium levels higher than 165 mmol/L in 17 centers (60%); intensive care unit stay with ventilation longer than 7 days in 16 centers (57%); serum glutamic oxalo-acitic transaminase levels higher than 90 U/L in 12 centers (42%); body mass indeces more than 30 in 10 centers (35%); serum glutamic pyruvic transaminase levels higher than 105 U/L in 10 centers (35%); serum bilirubin levels higher than 3 mg/dL in 10 centers (35%); and other criteria in 13 centers (46%). Twenty-three centers informed the transplant candidate of the ECD status of the donor: 10 centers (43%) when the patient registered for transplantation, 3 centers (14%) when an ECD liver became available, and 10 centers (43%) on both occasions. Ten centers required the liver transplant candidate to sign a special consent form. Ten centers informed the potential recipient of the donor's serology. Only three centers informed the potential recipient of any high risk behavior of the donor.
