Differences in the learning curve of robotic transabdominal preperitoneal inguinal hernia repair according to surgeon's robotic experience.

PURPOSE: In this study, we aim to analyze the learning curve of each step of robotic transabdominal pre-peritoneal inguinal hernia repair (rTAPP) in two surgeons with varying degrees of expertise with the robotic platform but no experience with laparoscopic hernia repair. METHODS: Data on 124 rTAPP cases performed by two surgeons were retrospectively reviewed. Cumulative sum (CUSUM) analysis was applied to visualize the learning curve of rTAPP on operation time of each step of the procedure [the peritoneal flap creation (T1), the completion of the critical view of the myopectineal orifice (T2), the mesh application (T3) and the peritoneal flap closure (T4)]. Each intraoperative and postoperative outcome was compared according to surgeon's experience with the robotic platform and learning phase. The robotic surgeon mentored the surgeon-in-training and was present during all surgeries in his learning period. RESULTS: The surgeon in training with the robotic platform showed a learning phase till the 20th procedure followed by a gradual improvement in performances. The expert surgeon showed a learning phase till the 35th procedure after which a constant decrease of operative time was recorded till the last procedure included. The operative times of each step of the procedures of both surgeons were significantly improved after the learning phase. In the late phase, the surgeon in training could achieve operative times in T2 and T3, which are similar to those of an experienced robotic surgeon with no experience with TAPP before the completion of the learning phase. CONCLUSIONS: In conclusion, the learning phase of rTAPP surgery may vary between 20 and 35 cases, depending on the surgeon's experience in robotic surgery.

Post treatment imaging in patients with local advanced cervical carcinoma.

Cervical cancer (CC) is the fourth leading cause of death in women worldwide and despite the introduction of screening programs about 30% of patients presents advanced disease at diagnosis and 30-50% of them relapse in the first 5-years after treatment. According to FIGO staging system 2018, stage IB3-IVA are classified as locally advanced cervical cancer (LACC); its correct therapeutic choice remains still controversial and includes neoadjuvant chemo-radiotherapy, external beam radiotherapy, brachytherapy, hysterectomy or a combination of these modalities. In this review we focus on the most appropriated therapeutic options for LACC and imaging protocols used for its correct follow-up. We explore the imaging findings after radiotherapy and surgery and discuss the role of imaging in evaluating the response rate to treatment, selecting patients for salvage surgery and evaluating recurrence of disease. We also introduce and evaluate the advances of the emerging imaging techniques mainly represented by spectroscopy, PET-MRI, and radiomics which have improved diagnostic accuracy and are approaching to future direction.

Strong impact of sarcopenia as a risk factor of survival in resected gastric cancer patients: first Italian report of a Bicentric study.

Gastric cancer (GC) accounts for 4% of all cancers in Europe. Sarcopenia is a complex syndrome characterized by a loss of muscle mass and function associated with age, often present in neoplastic patients. Recently, several studies have shown a significant association between sarcopenia and poor prognosis in various pathological conditions. The current observational retrospective study investigates the association between sarcopenia and overall survival (OS) and recurrence-free survival (RFS) in patients with GC undergoing up-front surgery with curative intent. Resected GC patients' clinical records and CT images were retrospectively assessed. The preoperative CT calculation of the skeletal muscle index (SMI) at L3 level allowed us to categorize patients as sarcopenic or not. Kaplan-Meyer and univariate and multivariate Cox regression analyses were performed to determine the difference in survival and presence of independent prognostic factors. Fifty-five patients, 28 male and 27 female, out of 298 studied for gastric cancer were enrolled in the current study from two cancer referral centers in Italy. The preoperative CT calculation of the SMI at L3 level allowed us to identify 39 patients with and 16 without sarcopenia. A statistically significant difference between the sarcopenic and non-sarcopenic groups was observed in both OS and RFS (p < 0.023; p < 0.006). Moreover, sarcopenia was strongly correlated to a higher risk of recurrence in univariate and multivariate analysis (p < 0.02). Sarcopenia can be considered a critical risk factor for survival in patients with resectable GC treated with up-front surgery. Identifying sarcopenic patients at the time of diagnosis would direct selection of patients who could benefit from early nutritional and/or physical treatments able to increase their muscle mass and possibly improve the prognosis. More extensive multicenter studies are needed to address this issue.

Laparoscopic versus open extended radical left pancreatectomy for pancreatic ductal adenocarcinoma: an international propensity-score matched study.

BACKGROUND: A radical left pancreatectomy in patients with pancreatic ductal adenocarcinoma (PDAC) may require extended, multivisceral resections. The role of a laparoscopic approach in extended radical left pancreatectomy (ERLP) is unclear since comparative studies are lacking. The aim of this study was to compare outcomes after laparoscopic vs open ERLP in patients with PDAC. METHODS: An international multicenter propensity-score matched study including patients who underwent either laparoscopic or open ERLP (L-ERLP; O-ERLP) for PDAC was performed (2007-2015). The ISGPS definition for extended resection was used. Primary outcomes were overall survival, margin negative rate (R0), and lymph node retrieval. RESULTS: Between 2007 and 2015, 320 patients underwent ERLP in 34 centers from 12 countries (65 L-ERLP vs. 255 O-ERLP). After propensity-score matching, 44 L-ERLP could be matched to 44 O-ERLP. In the matched cohort, the conversion rate in L-ERLP group was 35%. The L-ERLP R0 resection rate (matched cohort) was comparable to O-ERLP (67% vs 48%; P = 0.063) but the lymph node yield was lower for L-ERLP than O-ERLP (median 11 vs 19, P = 0.023). L-ERLP was associated with less delayed gastric emptying (0% vs 16%, P = 0.006) and shorter hospital stay (median 9 vs 13 days, P = 0.005), as compared to O-ERLP. Outcomes were comparable for additional organ resections, vascular resections (besides splenic vessels), Clavien-Dindo grade ≥ III complications, or 90-day mortality (2% vs 2%, P = 0.973). The median overall survival was comparable between both groups (19 vs 20 months, P = 0.571). Conversion did not worsen outcomes in L-ERLP. CONCLUSION: The laparoscopic approach may be used safely in selected patients requiring ERLP for PDAC, since morbidity, mortality, and overall survival seem comparable, as compared to O-ERLP. L-ERLP is associated with a high conversion rate and reduced lymph node yield but also with less delayed gastric emptying and a shorter hospital stay, as compared to O-ERLP.

Searching for novel multimodal treatments in oligometastatic pancreatic cancer.

BACKGROUND: Metastatic pancreatic cancer has a median overall survival of less than 12 months, even if treated with chemotherapy. Selected patients with oligometastatic disease could benefit from multimodal treatments connecting chemotherapy and surgical treatment or radiofrequency ablation (RFA) of metastases. CASE PRESENTATION: We present a patient with oligometastatic pancreatic cancer recurrence who was successfully treated with a multimodal therapeutic approach. A 57-year-old male initially presenting with resectable pancreatic cancer underwent pancreatoduodenectomy. The histopathological diagnosis revealed ductal pancreatic adenocarcinoma with positive surgical resection margins and negative lymph nodes. He completed six cycles of adjuvant therapy with gemcitabine (1000 mg/mq 1,8,15q 28), followed by external radiotherapy (54 Gy in 25 fractions) associated with gemcitabine 50 mg/mq twice weekly. Three years later, the patient developed multiple liver metastases, and he started FOLFIRINOX (oxaliplatin 85 mg/mq, irinotecan 180 mg/mq, leucovorin 400 mg/mq and fluorouracil 400 mg/mq given as a bolus followed by 2400 mg/mq as a 46 h continuous infusion,1q 14) as a first-line treatment. The CT scan showed a partial response after 6 cycles. After multidisciplinary discussion, the patient underwent a laparotomic metastasectomy of the three hepatic lesions. After additional postsurgical chemotherapy with 4 cycles of the FOLFIRINOX schedule, the patient remained free of recurrence for 12 months. A CT scan showed a new single liver metastasis, which was treated with radiofrequency ablation (RFA). A second radiofrequency ablation was performed when the patient developed another single liver lesion 12 months after the first RFA; currently, the patient is free from recurrence with an overall survival of 6 years from the diagnosis. CONCLUSIONS: Our case has benefited from successful multimodal treatment, including surgical and local ablative techniques and systemic chemotherapy. A multimodal approach may be warranted in selected patients with oligometastatic pancreatic cancer and could improve overall survival. Further research is needed to investigate this approach.

Caregivers in home palliative care: gender, psychological aspects, and patient's functional status as main predictors for their quality of life.

PURPOSE: This study aims to investigate the impact of possible predictors of quality of life (QoL) in a group of Italian caregivers assisting a cancer patient in home palliative care. METHODS: Data from 570 adult informal caregivers and their cancer-affected relatives were collected. A multivariate regression analysis was conducted to assess the effect of three groups of variables on Caregivers Quality of Life Index-Cancer (CQOLC) scale: (a) socio-demographic characteristics of caregivers; (b) psychological characteristics of caregivers assessed by Profile Mood of States (POMS), Caregiver Burden Inventory (CBI), and Preparedness for Caregiving Scale (PCS); (c) Socio-demographic characteristics and functional status of the patients assessed by Karnofsky Performance Status (KPS), Activities of Daily Living (ADL), and Instrumental Activities of Daily Living (IADL). RESULTS: Regression analysis shows that some variables from each of these clusters are significantly associated with CQOLC, in particular: (a) the gender of the caregiver (st.ß = .115, t = 2.765, p = .006) and the time spent for caregiving (st.ß = - .165, t = - 3.960, p < .001); (b) the scores obtained by the caregivers in POMS,CBI (st.ß = - .523, t = - 16.984, p < .001 and st.ß = - .373, t = - 12.950, p < .001, respectively) and PCS (st.ß = .092, t = 3.672, p < .001); (c) the gender (st.ß = - .081, t = - 1.933, p = .045) and the IADL score (st.ß = .195, t = 4.643, p < .001) of the patient. CONCLUSIONS: A multidimensional evaluation is a key strategy to identify the most vulnerable caregivers. Apart from the condition of the patient, the gender of the caregivers, the time spent for caregiving and, above all, their psychological condition are strong predictors of caregivers' QoL.

Care for Carers: an Investigation on Family Caregivers' Needs, Tasks, and Experiences.

Family caregivers have an essential active role in cancer patients assistance at home. They play a key role in the management of patients and provide some caregiving activities once provided only by professional caregivers. Often they are not adequately trained or prepared, however a systematic assessment of their needs is rarely practiced. For these reasons, this preliminary investigation was designed to better identify the needs and changes in the lifestyles of family caregivers of home cancer palliative care. Participants have completed a battery of self-report questionnaires, including the Caregiving Tasks Consequences and Needs Questionnaire (CaTCoN), that measures caregivers' experiences (the extent of cancer caregiving tasks and consequences) and the caregivers' needs, mainly concerning the interaction with the health care professionals. The results confirmed that cancer caregiving is burdensome. Large proportions of caregivers experienced substantial caregiving workload as well as a range of negative consequences, e.g. lack of time for social relations. Furthermore, considerable proportions of caregivers experienced problems or had unmet needs regarding the interaction with health care professionals. Prominent problematic aspects included the provision of enough information to the caregivers and attention to the caregivers' well-being and feelings. The assessment of caregivers' needs is a critical step for determining appropriate support services, providing high-quality care, achieving caregiver satisfaction, and decreasing caregiver burden. Findings of this investigation will certainly contribute to develop and publish Guidelines and to provide programmes and on-going education where caregivers feel supported in their role.

Impact of primary cancer features on behaviour of colorectal liver metastases and survival after hepatectomy.

Background: Markers of tumour biology may be valuable prognostic indicators after hepatic resection of colorectal cancer liver metastases (CRLMs). Identification of the aggressiveness of these metastases might inform the appropriateness of hepatic surgery. Methods: Patients undergoing liver resection for CRLMs between January 2001 and July 2013 in four tertiary hospitals were reviewed. A mathematical model to estimate CRLM doubling times was constructed for patients with metachronous metastases. Tumour doubling time was investigated in relation to the features of colorectal cancer, including KRAS status. The hazard rate for recurrence and death following hepatectomy was explored through the Kernel-smoothed estimator. Results: Of 1063 patients undergoing liver resection for CRLMs, 361 with metachronous metastases undergoing single-stage hepatectomy were analysed. The mean doubling time in patients not receiving chemotherapy between surgery for colorectal cancer and CRLM was 71·4 days. Tumour doubling time was shorter in patients with more advanced primary tumour stages, with mutant KRAS and in those who did not receive chemotherapy. For fast-growing CRLMs (doubling time less than 48 days), the risk of recurrence was highest within the first postoperative year, and was about 7 per cent per month. Conclusion: Primary features of colorectal cancer were linked to aggressiveness of CRLMs as measured by doubling time.

Radiotherapy in the management of gist: state of the art and new potential scenarios.

BACKGROUND: Gastrointestinal stromal tumor (GIST) is the most common mesenchymal neoplasm of the gastrointestinal tract. The main treatment for localized gastrointestinal stromal tumors is surgical resection. Unresectable or advanced GIST are poorly responsive to conventional cytotoxic chemotherapy but the introduction of tyrosine kinase inhibitors (TKIs) marked a revolutionary step in the treatment of these patients, radically improving prognosis and clinical benefit. Historically GIST has been considered radiation-resistant, and the role of radiotherapy in the management of patients with GIST is currently restricted to symptomatic palliation in current treatment guidelines. CASE PRESENTATION: Here we report two patients affected by metastatic GIST, treated with radiotherapy and radiosurgery in combination with TKIs, achieving an unexpected objective response in the first case and a significant clinical benefit associated with a local tumor control of several months in the second case. CONCLUSIONS: These and other successful experiences that are progressively accumulating, open up new scenarios of use of radiation therapy in various settings of treatment. GIST is not universally radioresistant and radiotherapy, especially if combined with molecularly targeted therapy, can improve the outcomes for patients diagnosed with GIST.

Antifungal prophylaxis in liver transplant recipients: one size does not fit all.

BACKGROUND: Targeted antifungal prophylaxis against Candida species or against Candida species and Aspergillus species, according to individual patient risk factors (RFs), is recommended by experts. However, recent studies have reported fluconazole is as effective as broader spectrum antifungals for preventing invasive fungal infection (IFI) after liver transplantation (LT). METHODS: We performed a retrospective cohort study of all adult patients who underwent LT at our 1420-bed tertiary teaching hospital, from June 2010 to December 2014, to assess the rate and etiology of IFI within 100 days after LT, to investigate the compliance with targeted prophylaxis, and to analyze risk factors for developing IFI. RESULTS: In total, 303 patients underwent LT. Patients were classified as having low (no RFs), intermediate (1 RF for invasive candidiasis [IC]), and high risk (1 RF for invasive aspergillosis [IA] or ≥2 RFs for IC) for IFI in 20%, 30%, and 50% of cases, respectively. A total of 139 patients received antifungal prophylaxis: 98 with a mold-active drug and 41 with fluconazole. Overall adherence to targeted prophylaxis was 53%. Nineteen patients (6.3%) developed IFI: 7 IC and 12 IA. Multivariate Cox regression analysis, adjusted for median model for end-stage liver disease score at LT, stratification risk group, and adherence to targeted prophylaxis, showed that graft dysfunction, renal replacement therapy, and prophylaxis with fluconazole were independent risk factors for IFI. Seven of the 9 patients who received fluconazole prophylaxis and developed IFI were classified as having high risk for IFI, and 6 developed IA. CONCLUSION: Recommended stratification is accurate for predicting patients at very high risk for IFI, who should receive prophylaxis with a mold-active drug.

Effect of age on survival in patients undergoing resection of hepatocellular carcinoma.

BACKGROUND: The benefit of surgical intervention for cancer should be estimated in relation to the life expectancy of the general population. The aim of this study was to provide a measure of relative survival after hepatectomy for hepatocellular carcinoma (HCC). METHODS: Consecutive patients with liver cirrhosis and HCC who underwent hepatectomy were divided into age quartiles for analysis. Short- and mid-term survival rates were used to estimate survival until death for all patients, in relation to age and other co-variables. Years of life lost (YLL) were estimated using a reference cohort, derived from the general population matched for sex, age and year of diagnosis. RESULTS: Some 919 patients were included in the study. The following age quartiles were identified: less than 60 years (229 patients), 60-66 years (230), 67-70 years (231) and over 70 years (229). Postoperative mortality rates were similar between age quartiles, as were survival rates up to 3 years (P = 0·404). A statistically significant reduction in 5-10-year survival rates was observed with ageing (P = 0·001). Relative survival calculation showed that the youngest age quartile (less than 60 years) experienced the longest entire postoperative lifespan (15·6 years) but also the greatest number of YLL (11·0 years). Patients aged over 70 years had the shortest entire postoperative lifespan (6·4 years) but also the smallest number of YLL (3·7 years). CONCLUSION: Although survival after liver resection for HCC is shortest in elderly patients, relative survival estimates suggest that hepatectomy can be of benefit in these patients, with a small loss of the entire individual lifespan.

Intrahepatic, peri-hilar and distal cholangiocarcinoma: Three different locations of the same tumor or three different tumors?

BACKGROUND: Few papers deal with pathologic characteristics and outcome of the 3 different cholangiocarcinomas based on location (intrahepatic, peri-hilar, distal). There is little evidence regarding similarity and differences. PATIENTS AND METHODS: From two tertiary referral Italian Centers (in Bologna and Verona), 479 patients with cholangiocarcinoma were evaluated between 1980 and 2011. Several pathologic characteristics and their impact on survival were analyzed among resected patients for cholangiocarcinomas depending on the site of origin. RESULTS: Tumour location was intrahepatic in 172 cases (36%), peri-hilar in 243 (51) and distal in 64(13%). Curative resection was performed in 339 (70%) patients. Intrahepatic cholangiocarcinoma showed higher probability to achieve R0 resection (81%), but was more frequently associated with presence of microvascular invasion (71%). Distal cholangiocarcinoma presented less R0 resections (58%), higher lymphnode involvement (60%) and lower microvascular invasion (49%). Hilar cholangiocarcinoma had intermediate characteristics (R0: 65% of cases). Median follow up was 30.2 ± 38 months; the 5 years overall survival was 31% in the resected population. Overall survival curves were similar among the three groups. At univariate analysis surgical margins, lymphnode status, perineural invasion, T category, TNM stage, microvascular invasion, tumour grading had significant impact on survival. At multivariate analysis, only microvascular invasion was significantly related to long term results (HR = 1,7; 95% CI = 1,0-2,5)". CONCLUSION: Micro-vascular invasion has the strongest impact on survival in all three types of cholangiocarcinoma. In case of comparable pathologic characteristics and stage, the three tumors show similar outcome; depending on location, it shows a different tendency to invade bordering structures which affect the outcome.

Risk factors for infection with carbapenem-resistant Klebsiella pneumoniae after liver transplantation: the importance of pre- and posttransplant colonization.

Improved understanding of risk factors associated with carbapenem-resistant-Klebsiella pneumoniae (CR-KP) infection after liver transplantation (LT) can aid development of effective preventive strategies. We performed a prospective cohort study of all adult patients undergoing LT at our hospital during 30-month period to define risk factors associated with CR-KP infection. All patients were screened for CR-KP carriage by rectal swabs before and after LT. No therapy was administered to decolonize or treat asymptomatic CR-KP carriers. All patients were monitored up to 180 days after LT. Of 237 transplant patients screened, 41 were identified as CR-KP carriers (11 at LT, 30 after LT), and 20 developed CR-KP infection (18 bloodstream-infection, 2 pneumonia) a median of 41.5 days after LT. CR-KP infection rates among patients non-colonized, colonized at LT, and colonized after LT were 2%, 18.2% and 46.7% (p < 0.001). Independent risk factors for CR-KP infection identified by multivariate analysis, included: renal-replacement-therapy; mechanical ventilation > 48 h; HCV recurrence, and colonization at any time with CR-KP. Based on these four variables, we developed a risk score that effectively discriminated patients at low versus higher risk for CR-KP infection (AUC 0.93, 95% CI 0.86-1.00, p < 0.001). Our results may help to design preventive strategies for LT recipients in CR-KP endemic areas.

Effect of age on native kidney function after adult intestinal transplants on long-term follow-up.

BACKGROUND: Kidney function usually deteriorates after intestinal transplant, with prevalence of renal failure almost 20% after 5 years. We report our results on adults from single institution over >10 years. METHODS: Forty-six patients were transplanted with 22 survivors; we divided them in 2 groups: Group 1, recipients with creatinine>1.2 mg/dL (normal, 0.50-1.2) and Group 2, normal creatinine. Group 1 included 12 patients (9 males) with a mean age of 42.8 years; all lived at home, with normal creatinine at transplant (apart from 1 patient with a creatinine of 1.6 mg/dL), and were mainly transplanted for short bowel syndrome. One underwent retransplantation. Immunosuppression was based on alemtuzumab (8 recipients) plus tacrolimus (FK). Group 2 included 10 patients (6 males) with a mean age of 34.7 years; all lived at home, had normal creatinine at transplantation, and were mainly transplanted for short bowel syndrome. Immunosuppression was mainly based on alemtuzumab (8 recipients) plus FK. RESULTS: There were no relevant differences between the 2 groups regarding number of recipients, sex, baseline creatinine at transplant, reason for transplantation, retransplantation, immunosuppression, antifungal or antiviral therapy, hospitalization, total parenteral nutrition (or fluids), or stoma. The only relevant difference was age (P=.04); patients with deteriorated kidney function or altered creatinine were found to be older.

Imaging in resectable colorectal liver metastasis patients with or without preoperative chemotherapy: results of the PROMETEO-01 study.

BACKGROUND: The aim of the PROMETEO-01 Study was to define the diagnostic accuracy of imaging techniques in colorectal cancer liver metastasis (CRCLM) patients. METHODS: Patients referred to Bologna S. Orsola-Malpighi Hospital performed a computed-tomography scan (CT), magnetic resonance (MR), 18F-FDG-PET/CTscan (PET/CT) and liver contrast-enhanced-ultrasound (CEUS); CEUS was also performed intraoperatively (i-CEUS). Every pathological lesion was compared with imaging data. RESULTS: From December 2007 to August 2010, 84 patients were enrolled. A total of 51 (60.71%) resected patients were eligible for analysis. In the lesion-by-lesion analysis 175 resected lesions were evaluated: 67(38.3%) belonged to upfront resected patients (group-A) and 108 (61.7%) to chemotherapy-pretreated patients (group-B). In all patients the sensitivity of MR proved better than CT (91% vs 82%; P=0.002), CEUS (91 vs 81%; P=0.008) and PET/CT (91% vs 60%; P=0.000), whereas PET/CT showed the lowest sensitivity. In group-A the sensitivity of i-CEUS, MR, CT, CEUS and PET/CT was 98%, 94%, 91%, 84% and 78%, respectively. In group-B the i-CEUS proved equivalent in sensitivity to MR (95% and 90%, respectively, P=0.227) and both were significantly more sensitive than other procedures. The CT sensitivity in group-B was lower than in group-A (77% vs 91%, P=0.024). CONCLUSIONS: A thoraco-abdominal CT provides an adequate baseline evaluation and guides judgment as to the resectability of CRCLM patients. In the subset of candidates for induction chemotherapy to increase the chance of liver resection, the most rational approach is to add MR for the staging and restaging of CRCLM.

Disease-related intestinal transplant in adults: results from a single center.

Intestinal transplantation is gaining worldwide acceptance as the main option for patients with irreversible intestinal failure and complicated total parenteral nutrition course. In adults, the main cause is still represented by short bowel syndrome, but tumors (Gardner syndrome) and dismotility disorders (chronic intestinal pseudo-obstruction [CIPO]) have been treated increasingly by this kind of transplantation procedure. We reviewed our series from the disease point of view: although SBS confirmed results achieved in previous years, CIPO is nowadays demonstrating an excellent outcome similar to other transplantation series. Our results showed indeed that recipients affected by Gardner syndrome must be carefully selected before the disease is to advanced to take advantage of the transplantation procedure.

Hepatolithiasis-associated cholangiocarcinoma: results from a multi-institutional national database on a case series of 23 patients.

AIMS: Few papers focused on association between hepatolithiasis (HL) and cholangiocarcinoma (CCC) in Western countries. The aims of this paper are to describe the clinical presentation, treatment, and postoperative outcomes of CCC with HL in a cohort of Western patients and to compare the surgical outcomes of these patients with patients with CCC without HL. MATERIALS AND METHODS: Among 161 patients with HL from five Italian tertiary hepato-biliary centers, 23 (14.3%) patients with concomitant CCC were analyzed. The results of surgery in these patients were compared with patients with CCC without HL. RESULTS: The 60.9% of patients with HL received the diagnosis of CCC intra- or postoperatively, with a resectability rate of 91.3%. The postoperative morbidity was 61.6%. The 1- and 3-year survival rates were 78.6% and 21.0%, respectively. The recurrence rate was 44.4% and the 3-year disease-free survival rates were 18.8%. The comparison with patients with CCC without HL showed a higher resectability rate (p = 0.02) and a higher frequency of earlier stage (p = 0.04) in CCC with HL. Biliary leakage was more frequent in CCC with HL group (p = 0.01) compared to CCC without HL group. We found no differences in overall and disease-free survival between the two groups. CONCLUSIONS: Patients with HL and CCC showed a high resectability rate but a higher morbidity. Nevertheless, overall and disease-free survival of patients with CCC and HL showed no differences compared to those of patients with CCC without HL. Also in Western countries, HL needs a careful management for the possible presence of CCC.

Assessment of perioperative transfusion requirement for cirrhotic patients undergoing elective hepatectomy.

BACKGROUND: The possibility of outlining a risk profile for perioperative blood transfusion of cirrhotic patients submitted to hepatic resection can help to rationalize transfusion policy. METHODS: Data from 323 hepatic resections, performed in cirrhotic patients, were reviewed. Bootstrap and a leave-one-out logistic regressions were applied to test the accuracy of available risk scores for peri-operative transfusion identified from PubMed search of the last 20 years, to refine them, and to provide internal validation for present results. RESULTS: One-hundred-six patients (32.8%) required blood transfusions during either intra- and/or postoperative. The predictive accuracy of three identified risk scores was poor with the area under receiver operating characteristics (AUROC) curves <0.70 in all cases. Tumor diameter, hemoglobin and presence of coronary artery disease were confirmed, in the present cohort, as predictors of blood transfusion together with serum albumin and bilirubin. The leave-one-out logistic regression results in an AUROC of 0.80, and of 0.79 for internal validation, significantly higher than that of the three scores tested (P<0.001). A Maximal Surgical Blood Order Schedule stratification was proposed. CONCLUSION: The risk profile for transfusion of cirrhotic patients undergoing hepatectomy can be better assessed with a model that combines already known clinical factors and hepatic function indexes.

Kidney preservation: review of present and future perspective.

One of the main problems in transplant surgery is the preservation of the organ during the cold ischemic time. The interrupted blood supply triggers a cascade of biological modifications resulting in cell death, which predisposes to discharge of a large quantity of toxic metabolites at the moment of organ reperfusion. Many approaches have been studied to prevent the toxic processes. Immediately after procurement, kidneys are flushed with these solutions. Two main: techniques of organ preservation are cold static storage and hypothermic machine perfusion (HMP). Based on age and comorbidities, individuals can be generally divided into 2 groups: ideal and marginal donors. Characteristics of organs from marginal donors are associated with an increased rate of delayed graft function and primary graft nonfunction (PNF), which reduce transplant survival and increase the acute rejection risk. In the last 20 years, the United Network of Organ Sharing has reported a 170% increase in deceased donors older than 50 years of age. Techniques of perfusion have been demonstrated to play a pivotal role in graft function after transplantation. Some studies suggest that HMP may improve outcomes after transplantation.

Induction therapy with alemtuzumab (campath) in combined liver-kidney transplantation: University of Bologna experience.

BACKGROUND: Combined liver-kidney transplantation (LKT) is considered to be a safe procedure, but the appropriate immunosuppressive regimen is unclear. PATIENTS AND METHODS: Between January 1997 and October 2011, 55 patients were listed for LKT: 45 (82%) were effectively transplanted, 5 (9.2%) died whereon here the waiting list, 3 (5.5%) temporarily out of waiting list, 1 (1.8%) was on waiting list and 1 (1.8%) refused LKT. Five LKTs treated with cyclosporine (CyA) were excluded from the analysis. Mean recipient age was 50.32 ± 10.32 years (14-65), MELD score at time of LKT was 19.22 ± 4.69 (8-29), mean waiting list time was 8.14 ± 9.50 months (0.1-35.76), and follow-up, 4.09 ± 3.02 years (0.01-10.41). Main indications for LKT were policystic disease (n = 15; 37%), hepatitis virus C (HCV)-related cirrhosis (n = 9; 22%) metabolic disease (n = 5; 13%), hepatitis virus B (HBV) cirrhosis (n = 4; 10%), alcoholic cirrhosis (n = 4; 10%), and cholestatic disease (n = 3; 8%). Immunosuppressive regimen was based on tacrolimus and steroids in 40 cases with induction therapy with alemtuzumab (Campath; 0.3 mg/kg) in 13 of 40 instances cases administered on day 0 and day 7. RESULTS: Postoperative mortality was 2.5%. Acute cellular rejection episodes were biopsy-proven in 2 (5%) cases, post-LKT infections developed in 17 cases (42.5%), and de novo cancer developed in 3 (7.5%) cases. Similar 5-year overall survivals were obtained irrespective of the LKT indication: 100% in cholestatic and alcoholic cirrhosis patients, 86% in policystic disease, 75% in metabolic disease and HBV patients, and 66% in HCV cirrhosis. Overall survivals for the alemtuzumab vs without-induction therapy groups at 1, 3, and 5-years were 100%, 85.7%, and 85.7% vs 76%, 76%, and 70%, respectively (P = .04). CONCLUSION: An immunosuppressive regimen based on tacrolimus and steroids with induction therapy with alemtuzumab was safe, with excellent long-term results for combined LKT.
