Triple-layer Mesh Plasty for Re-recurrent Ventral Hernia in a Liver Transplant Patient: A Case Report.

Ventral hernias often occur in transplanted patients because of weakness of the abdominal wall, poor muscle mass, and ascitis. In this report we describe the case of a re-recurrent ventral hernia seen emergently in a liver transplant recipient, who was treated using a singular 3-layer approach by placement of an intraperitoneal mesh, stressing technical aspects of the plasty as well as the importance of a sublay technique in the reinforcement of a previous prosthetic plasty.

Ageing successfully with haemophilia: A multidisciplinary programme.

INTRODUCTION: Persons with haemophilia (PWH) born before the middle 1970s have spent a substantial part of their lives without the benefits of replacement therapy, that became available on a relative large scale only during the 1970s. As a consequence, this group of PWH, although still relatively young, suffers from musculoskeletal and functional problems that are typical of old people. METHODS: We report herewith the short-term results of a project based upon a multidisciplinary training programme led by a physiotherapist and an occupational therapist, that was implemented over a period of 12 months in 40 patients with severe or moderate hemophilia A or B born before the middle 1970s and regularly followed-up at a comprehensive haemophilia treatment centre in Italy. The project was aimed to provide information and skills in order to empower the older PWH carrying physical handicaps and functional limitations that had resulted from the inadequate management in their early ages, and to enable them to cope more efficiently with their crippling disease and prevent further disabilities. RESULTS AND CONCLUSIONS: The comparison of the data obtained before and after the 12-month programme found marginal improvements, but the purpose of this programme was indeed to offer a blueprint for the future. In this respect, the level of satisfaction for the programme was very high and we expect that it will be implemented long-term by our older PWH.

Antifungal prophylaxis with liposomal amphotericin B and caspofungin in high-risk patients after liver transplantation: impact on fungal infections and immune system.

Antifungal prophylaxis may be required in high-risk patients undergoing liver transplantation and for that reason we aimed to verify its role and its related impact on the graft. From January 2006 throughout 2012, 250 liver transplants were evaluated and 54 patients identified as being at higher risk were randomly selected to undergo the following schedule: 28 patients received liposomal amphotericin B and 26 received caspofungin. We evaluated, throughout 12 months, renal and liver function tests, bacterial and fungal infection episodes, and intensive care unit (ICU) stay, as well as the Th1 and Th2 cytokine network. Differences were analyzed according to non-parametric tests (two-tailed p values). Neither of the groups showed episodes of invasive fungal infection during the 12 months follow-up; however, patients receiving prophylaxis with liposomal amphotericin B had reduced episodes of bacterial infections coupled with an improved immune system response compared with those receiving caspofungin. Finally, a reduced stay in the ICU was also observed. In conclusion, even if the results of liposomal amphotericin B and caspofungin prophylaxis strategies did not differ in terms of invasive fungal infection rate, patients receiving prophylaxis with liposomal amphotericin B had a reduced ICU stay and an improved Th2 status, as well as a reduced number of post-transplant bacterial infections. Further studies are required to better address and evaluate these findings.

Telbivudine prophylaxis for hepatitis B virus recurrence after liver transplantation improves renal function.

INTRODUCTION: Renal impairment after liver transplantation represents an important issue in the management of transplantation patients, particularly when those subjects may need prophylaxis for fungal or viral infection. Herein we report our experience with 12 transplantation patients receiving telbivudine 600 mg/d while on the waiting list, followed by treatment for 18 months after liver transplantation, showing an improvement on their renal function during the follow-up period. METHODS: Our series consisted of men with hepatitis B virus (HBV)-related end-stage liver disease. The viral load decreased rapidly while on the waiting list once the patient was started on antiviral treatment. Those subjects were compared with 12 patients on lamivudine prophylaxis. All patients were evaluated for liver and renal function, immunosuppression trough levels, and creatine phosphokinase (CPK) before liver transplantation (T0) and at 3, 6, 12, and 18 months (T3, T6, T12, T18). RESULTS: All patients received a calcineurin inhibitor immunosuppression-based regimen. Creatinine clearance (Modification of Diet in Renal Disease) was 67 mL/min at T0, with a statistically significant improvement after month 6 compared with those on lamivudine and with the value at the beginning of the prophylaxis (Mann-Whitney U test P<.05). Neither CPK nor transaminase serum levels increased throughout the study period. Once HBV DNA was cleared while on the waiting list, it remained negative throughout the follow-up period. CONCLUSIONS: Telbivudine prophylaxis for HBV is safe and effective, without any significant deleterious effect on the liver; on the contrary, it seems to improve renal function after liver transplantation through 18 months. Further studies and larger series are warranted to confirm these findings.

Side-to-side cavocavostomy in adult piggyback liver transplantation.

OBJECTIVE: Our objective was to perform a retrospective study that described the anastomosis technique as well as the complications of side-to-side cavo-caval reconstruction. PATIENTS AND METHODS: From June 1998 to April 2011, we performed 284 liver transplantations including 10 adults with live donor organs. In all cases but 2 (272), cavo-caval reconstruction was performed using side-to-side cavo-caval (STSCC) anastomosis. In 19 cases (6.9%), we also carried out an end-to-side temporary porto-caval shunt (TPCS). In 17 cases (6.2%) the technique was performed for retransplantation. RESULTS: STSCC anastomosis was technically feasible in all but 2 cases, regardless of the recipient's vena cava, anatomic factors, or graft size. Mean operative time for the STSCC was 13 minutes (range, 6-25). Routine Doppler ultrasonography was performed intraoperatively at the end of the surgery. There was no case of cava stump thrombosis. Complications associated with this technique were limited to 2 patients. One complication was torsion due to donor graft/recipient mismatch, which was successfully treated surgically by falciform ligament fixation. The second complication was only evident by sinusoidal congestion and was managed nonoperatively. Seventeen cases were uneventful for retransplant recipients. CONCLUSIONS: STSCC during piggyback liver transplantation is safe and can be performed in the retransplantation setting, with a low incidence of venous outflow obstruction that can be associated with the traditional piggyback technique. Our data suggest that donor graft to recipient mismatch is not an absolute contraindication when proper body size match is considered. A wide anastomosis with typical recipient hepatic vein inclusion is warranted with routine postanastomotic Doppler ultrasonography.

Role of liposomal amphotericin B prophylaxis after liver transplantation compared with fluconazole for high-risk patients. impact on infections and mortality within one year.

BACKGROUND: Fungal infections are still one of the most important issue in liver transplant patients, contributing considerably to both morbidity and mortality. Few studies have been published comparing antifungal protocols for their impact on liver transplant (OLT) patients. The aim of this study was to evaluate the effects of liposomal amphotericin B compared with fluconazole prophylaxis on morbidity and mortality after liver transplantation. METHODS: We evaluated all 44 patients undergoing OLT from January 2006 to January 2009 who were enrolled and randomized to undergo treatment with Amphotericin B (3 mg/kg/d; group A = 25 patients) or fluconazole (800 mg Loading dose and thereafter 400 mg/d according to renal parameters and immunosuppressant trough levels; group B = 18 patients) for at least 7 to 14 days with 12 months follow-up after liver transplantation. A multivariate analysis assessed factors associated with infections and mortality. RESULTS: Neither antifungal prophylaxis was associated with a fungal episode; however, group A patients experienced fewer bacterial infectious episodes (Mann-Whitney U test P < .05). Furthermore, no renal impairment was observed in either groups. Nonetheless, patients undergoing fluconazole prophylaxis showed significant increases in immunosuppressive trough levels requiring dose adjustment. CONCLUSION: We observed comparable results of fluconazole and liposomal amphotericin B to prevent invasive fungal infections throughout 12 months after surgery. The latter drug was associated with fewer bacterial infections after liver transplantation.

Telbivudin as prophylaxis for hepatitis B virus recurrence after liver transplantation: a case series in single-center experience.

BACKGROUND: Hepatitis B virus (HBV) recurrence after orthotopic liver transplantation (OLT) represents a severe condition that requires prophylaxis with specific immunoglobulin and lamivudine. Few studies have addressed the efficiency of other effective antiviral drugs posttransplantation or their impact on early renal function after transplantation. Herein, we have reported experience among seven transplanted patients prescribed Telbivudin (600 mg/d) while on the waiting list followed by treatment for 3 months after OLT. METHODS: Our series consisted of men with HBV-related end-stage liver disease. Once the patient started antiviral treatment, the viral load decreased rapidly while on the waiting list. All patients were evaluated for liver and renal functions immunosuppressive drug trough levels, CPK before (T0), as well as at 1 month (T1), and 3 months after liver transplant (T3). RESULTS: All patients received a CNI-based regimen. Their mean creatinine clearance (MDRD) was 72.5 mL/min at T0, 69.2 mL/min at T1, and 71.0 mL/min at T3. Neither CPK or serum transaminase levels increased throughout the study. Once HBV-DNA was cleared while on the waiting list, it remained negative throughout the follow-up period. CONCLUSION: Telbivudin prophylaxis for HBV was safe and effective without any significant deleterious effect on liver or renal function tests after liver transplantation.

Multiorgan retrieval and horseshoe kidney: case report.

Horseshoe kidney, a congenital anatomic condition with fusion of the kidney poles, causes the organ to be placed around the aorta usually below the origin of the mesenteric artery. This congenital disorder affects about 1 in 400 people. Retrieval for multiorgan transplantation dissects and canulates major abdominal vessels, aorta and vena cava, below the renal vessels to infuse refrigerated preservation solution. The presence of a horseshoe kidney could be a hazard for the retrieval team when cannulating when following standard techniques. We have described herein a surgical maneuver exposing the anterior surface of the aorta for canulation. We transected the horseshoe kidney in the midline with the use of a linear cutter stapler GIA 60 mm (Ethicon), after previously ligating both kidney pedicles. This technique was safely performed without the need for cannulation through the iliac vessels.

Severe spontaneous properitoneal hemorrhage following ventral hernia repair caused by viral infection: report of a case.

The authors report a case of severe spontaneous hemorrhage in a patient who underwent surgical repair of an upper umbilical ventral hernia with placement of a polypropylene mesh. On the third postoperative day the patient experienced bleeding in the properitoneal space (above and below the mesh), which spread up to and along the retroperitoneal area, causing severe hypovolemic shock. Postoperative investigations finally identified a virus as the cause of the complication.

Elevated CD4+/CD25+ T-cell frequency and function during hepatitis C virus recurrence after liver transplantation.

BACKGROUND/AIM: Factors involved in hepatitis C virus (HCV) recurrence versus acute cellular rejection are not fully understood. The aim of the present study was to investigate whether patients with recurrence after liver transplantation (OLT) showed similar CD4(+)/CD25(+) cell frequency and function as those who became chronically infected. PATIENTS AND METHODS: After written informed consent, we enrolled 20 patients (group A) who underwent OLT with HCV recurrence within 6 months. HCV-RNA and hypertransaminasemia were used to assess the reactivation of viral hepatitis. CD4(+)/CD25(+) T cells were enumerated using a flow cytometry assay, gated on CD3 cells, stained for FoxP3. After immunomagnetic sorting (Dynal, Oslo, NW), Treg suppressor activity was measured, as the ability to inhibit proliferation of autologous CD4(+)/CD25(-) T cells (anti-CD3/CD28 stimulation-1:2, 1:20 ratio). Eight patients with acute hepatitis C who evolved to a chronic infection after 6 months (group B) were used as positive controls, while 10 healthy individuals were negative controls (group C). RESULTS: We did not observe any difference in CD4(+)/CD25(+) frequency or function among group A compared with group B (CD4(+)/CD25(+) = 14% +/- 2% versus CD4(+)/CD25(+) = 16% +/- 3%), although both groups were significantly increased with respect to group A (CD4(+)/CD25(+) = 6% +/- 3%; Mann-Whitney U test, P < .01). CONCLUSION: Patients developing HCV recurrence after OLT have the same immunoregulatory network as patients with acute hepatitis C evolving to persistent infection, likely suggesting that CD4(+)/CD25(+) numbers may be a marker to predict recurrence of HCV after OLT.

Evidence of liver histological alterations in apparently healthy individuals evaluated for living donor liver transplantation.

BACKGROUND: Living donor liver transplantation (LDLT) represents an important therapeutic option for patients with end-stage liver disease (ESLD). It has been reported that steatosis may be a serious problem in patients who donate a part of their liver. Liver biopsy represents an accepted method to assess the rate of steatosis and the possible risk to the donor. Nonetheless, some histological abnormalities have been documented in the specimens from potential donors. The aim of this study was to evaluate the possible hepatic histological alterations among apparently healthy candidates for liver donation who did not show serological or ultrasound (US) evidence. MATERIALS AND METHODS: From January 1, 2005 until October 15, 2006, we performed virological, biochemical, and tumor marker evaluations and liver biopsies on 20 LDLT donor candidates. At histological evaluation we classified the evidence of steatosis (5%-10% or 10%-20%), fibrosis (absent or 1-3 portal space), inflammation, iron deposition, biliary neoductulation, and portal vein vascular alterations. RESULTS: Among the 20 subjects, serological markers did not show any pathological alterations. At liver biopsy we found: steatosis (5%-10%) in 6 individuals (about 30%) with 1 ranging from 10% to 20%; iron deposition in 4 (20%); biliary neoductulation in 3 (about 16%); fibrosis in 4 (20%); inflammation in 5 (25%); and portal vein dilatation in 10 (50%). CONCLUSIONS: Our data showed that apparently healthy individuals who did not display serological markers or US evidence of pathology had liver histological abnormalities. This result suggested that in absence of clinical or laboratory alterations, liver biopsy may represent a useful diagnostic tool for living donor candidates. Long-term follow-up results for the laboratory data among those patients should be performed even though they were not qualified for LDLT.

Surgical treatment with Ligasure Precise of schwannoma of brachial plexus: case report.

English version We present a case of bulky schwannoma arising from the brachial plexus treated by a new surgical device. A 38-year-old man presented with a slow-growing left-sided supraclavicular mass and complained paresthesia of the third and forth fingers of the hand and forearm weakness. Physical examination revealed Tinel's sign. A CT-scan revealed a solid mass situated in the left profound supraclavicular fossa. The tumour was resected with the utilization of bipolar vessel sealing system (Ligasure Precise). This device is very useful in sutureless removal of masses localized in deep supraclavicular fossa. During the operation, care was taken to preserve the nerve function.

[Male breast cancer. Five years experience and literature review]. / Il cancro della mammella maschile. La nostra esperienza di 5 anni e confronto con la letteratura internazionale.

Male breast cancer is an uncommon disease and its aetiology, clinical behaviour and treatment is not well-known . Retrospective studies show that age and stage-matched breast cancer in men and women are compared. Nevertheless, the poor mammary tissue in man allow a rapid local infiltration, late diagnosis and poor survival rate. The Authors report their five years experience and with a short literature review they summarise what is currently known about this uncommon neoplasm in terms of prognostic factors, therapy and survival.

[Thyroid microcarcinoma: our experience]. / Microcarcinoma tiroideo: nostra esperienza.

Differentiated thyroid cancer had an excellent prognosis; the diagnosis of sub-centimetric differentiated cancer (microcarcinoma) is more and more frequently. Clinical evolution of microcarcinoma could be various: microcarcinoma can represent an autoptic finding or can evolve with locoregional lymph node involvement or metastasis. Various clinical and genetic factors have been considered to predict the aggressiveness of this neoplasm. From 2001 to 2004, 74 patients with diagnosis of thyroid microcarcinoma underwent surgical treatment. By a retrospective survey we evaluated risk factors and the choice of surgical treatment. The aggressiveness appear to be related mainly to multifocality and size. Our therapeutic strategy is to perform total thyroidectomy for benign pathologies, total thyroidectomy with lymphadenectomy in cases with preoperative diagnosis of microcarcinoma.

Breast surgery and sentinel node biopsy. Our experience.

Massive campaigns of screening of breast pathologies improved early diagnosis of breast cancers. Most of these cancers are small-sized (T1) and seldom show intraoperative nodal involvement. Sentinel node biopsy is the elective choice in the above mentioned cases because, if negative, it avoids axillary dissection. International literature reports rates of false negative sentinel node biopsy ranging among 4.5 and 12%; results in our experience account for almost 6%. As a consequence, there is the definite risk of potentially positive axilla that will not be dissected with subsequent risk of axillary recurrence within 24 months. The reason of that could be related to the fact that in Referral Centers this technique is performed in strictly selected patients, so as to gain a diagnostic accuracy of 98%. The rate of axillary recurrences does not justify the routine axillary dissection, since this is just a staging, not a therapeutic procedure. In case of doubt, it can be recommended a close and careful follow-up of the axilla.

Seeding from hepatocellular carcinoma after percutaneous ablation: color Doppler ultrasound findings.

BACKGROUND: We describe the clinical and color Doppler ultrasound findings in a series of cases of seeding from hepatocellular carcinoma (HCC) observed in patients treated with percutaneous ablation therapy (PAT) over a 15-year period. METHODS: We reviewed the clinical and imaging records of 12 patients with cirrhosis (nine men and three women, age range 51-82 years, mean age 63 years) that showed neoplastic seeding from HCC occurring after one or more PAT procedures. Five of 12 cases of seeding were observed as a complication of 1080 PAT procedures (0.46%) performed in 545 patients (0.96%) by two of the authors (L.T., G.F.) over a long period (15 years) at different institutions. The other seven patients had been treated with PAT procedures at other institutions and had come to our attention during post-treatment follow-up. RESULTS: The 12 patients who had seeding nodules had undergone the following PAT procedures: multisession conventional percutaneous ethanol injection (PEI) without anesthesia (four patients), single-session PEI with general anesthesia (three patients), single-session PEI with general anesthesia plus multisession conventional PEI (four patients), and single-session PEI plus radiofrequency ablation (one patient). Seeding nodules ranged from 0.9 to 6.0 cm (mean 1.7 cm). Eleven of 12 seeding nodules appeared as hypervascular hypoechoic nodules with smooth and regular margins and multiple intralesional vascular signals. CONCLUSIONS: Clinical and imaging findings of seeding from HCC should be recognized by physicians who perform follow-up ultrasound examinations of patients who are treated with PAT. Early diagnosis of seeding can be reliably made by scanning the abdominal wall with small probes in the area where the previous PAT has been performed. Hypoechoic hypervascular pattern of the seeding nodule allows definitive diagnosis.

[Bile leakage after laparoscopic cholecystectomy: report of three cases in our experience]. / Coleperitoneo dopo colecistectomia laparoscopica: descrizione di tre casi nella nostra esperienza.

Laparoscopic cholecystectomy (LC) is associated with an higher incidence of bile duct injury than open cholecystectomy. There has been concern and the reason why bile leakages are more frequent with LC is yet unclear. Bile collections can occurr because of major about (75%) or minor (about 25%) injuries. Anyway, external biliary decompression is a key factor in the treatment, in order to avoid an emergency intervention. The Authors report their experience concerning 3 cases of bile leakages among a series of 458 LC. Only in one of the three cases the subhepatic space was not drained and an emergency laparotomy was performed. The Authors, on the basis of their own experience and of the data reported in literature, suggest the routinary intraoperative placement of a drainage into the subhepatic space, to be removed, if no complications occur, one day after surgery.

[Interstitial laser photocoagulation in liver tumours: our experience]. / Laserterapia interstiziale nell'epatocarcinoma su cirrosi: nostra esperienza.

Interstitial lasertherapy (ILT) is one of the percutaneous thermal procedures allowing the ablation of primary or secondary hepatic lesions. This technique can be performed without general anaesthesia, since the patient is completely painless, in spite of the high temperatures reached, because there are no sensitive fibers around the lesion. This study includes patients with small hepatocarcinomas (< 2 cm) non peripherically sited, far from the gallbladder and the hepatic hilum. Twenty patients suffering from 24 cirrhotic hepatocarcinomas (two patients showed two nodules) have been enrolled for the present study. Mean diameter of lesions was 1.8 cm (1.3-2 cm). One or more 21 G (length 20 cm) Chiba's needles were inserted under sonographic view into the lesions. The laser energy was switched on at 4 Watts for 4-6 minutes, until an amount of energy of 900-1800 Joule was reached. All the patients were discharged 48 hours after the procedure. Triphasic CT-scan with contrast were performed 7 to 14 days after ILT, in order to check its efficacy. CT-scan showed complete necrosis in all the nodules ranging from 1.5 to 3 cm. All the patients received only one IL T session, whose longest duration was 20 minutes. No major complications occurred. ILT of small hepatocarcinomas is a safe, efficient procedure, also feasible without anaesthesia. Differently from percutaneous radiofrequency, in fact, it shows the advantage of less pain, that can avoid the need for general anaesthesia.

Which therapy to prevent post-thyroidectomy hypocalcemia?

Hypocalcemia is one of the most frequent complications after total extracapsular thyroidectomy (TET). In most of cases it is a transient phenomenon. The aim of this study is to evaluate if and how the oral administration of calcium or calcium combined with D-vitamin could effectively prevent post-thyroidectomy hypocalcemia. A randomized prospective study was performed, recruiting 120 patients who underwent total thyroidectomy. The patients in our series were randomly assigned to one of two groups: group A--patients who received calcium lactogluconate/calcium carbonate (mg 300 per day); group B--patients who received calcium carbonate/cholecalciferol therapy (calcium carbonate: 1500 mg per day; cholecalciferol 400 UI per day). The groups were well matched for age, sex and pathologies. Patients of both A and B groups were divided in two subgroups: those operated on for benign thyroid diseases (A1 and B1) and those operated on for malignancy (A2, B2). Serum calcium assays, performed 24, 48 and 72 hours after surgery, showed mean values of calcemia higher in patients of the B1 and B2 group. Statistical analysis was performed using a Student's t test. Mean serum calcium concentrations on post-operative day one, two and three were higher in patients of the group B (p<<0.01). Early and combined oral administration of both calcium and vitamin D seemed to prove major efficacy in preventing and treating post-operative hypocalcemia, showing mean serum calcium levels higher than those of patients who received only oral calcium administration. Nevertheless, further studies are necessary to validate these data.

Major complications in thyroid surgery: utility of bipolar vessel sealing (Ligasure Precise).

In the present study the Authors tried and assess the advantages of the standard sutureless thyroidectomy performed by the Ligasure Vessel Sealing System, thanks to the use of the dedicated Precise handle. The Authors compared the efficacy of haemostasis and the economical impact of the device, in terms of drug administration and costs. The Authors comparatively analyzed 120 total extracapsular thyroidectomies (TET) performed by the standard operative technique (Group A, control) and 70 TET achieved by the "sutureless technique" (Group B, case). There was a statistically significant decrease of transient postoperative hypocalcemia (5.71% vs 7.5%) and also of mean operative time (about 20 minutes) in patients of the group B. Non significant decrease of other kind of complications (postoperative hemorrhage, transient and permanent inferior laryngeal palsy, stupor of the superior laryngeal nerve, seromas) were also observed. The use of the Ligasure Precise resulted easy, safe and efficient in the Authors' experience. It allowed the decrease of postoperative haemorrhages and mean operative time.
