RESUMEN
BACKGROUND: Hepatic resection represents the best treatment for primary and metastatic liver tumors but is not always feasible. In early 1980, Piclmayr described a complex liver resection technique, termed "ex vivo liver resection," for the treatment of locally advanced tumors not conventionally resectable. The authors approached this technique with translational research in a preclinical setting and then similarly reproduced it in human patients. METHODS: In the swine median xyphopubic laparotomy, the liver was mobilized to expose the vena cava. A temporary porto-caval shunt was previously prepared on the back table using a segment of thoracic aorta, and a vascular anastomosis between the supra-hepatic vena cava and a caval graft was quickly performed. The liver was placed in a machine perfusion system and continuously perfused for 2 h for its final implantation orthotopically in the same animal. The anastomoses were performed as usual. Based on this experience, the intervention was reproduced in the human model of a 39-year-old woman affected by large intrahepatic cholangiocarcinoma considered unresectable.' RESULTS: All animals survived the procedure. The peak aspartate aminotransferase level (460 ± 87 U/L) was recorded 60 min after reperfusion. Lactate levels flared up for 120 min (3.6 ± 0.2 mmol/L). In the clinical case, the postoperative period was uneventful, and the patient was discharged on day 22. CONCLUSIONS: The described procedure is feasible only for surgeons with a transplantation background. The study showed that this translational approach enhances the surgeon's ability to perform the intervention systematically in a shorter time and with a good outcome.

BACKGROUND: Laparoscopic microwave ablation and portal vein ligation for staged hepatectomy (LAPS) is a new technique with a first laparoscopic step available in cases of unresectable right liver masses and inadequate future liver remnant (FLR). METHODS: In Step 1, laparoscopic right portal vein occlusion is performed with microwave ablation on the future transection plane and in the FLR. Step 2 consists of a totally laparoscopic right trisectionectomy. RESULTS: Duration of the Step 1 operation was 170 min, without the need for blood transfusions and intensive care unit admission. The postoperative liver volumetric computed tomography scan was performed on postoperative day 9 and revealed a satisfactory left hepatic hypertrophy (FLR 666 cm(3); FLR to body weight ratio 0.96; FLR increase 90.4 %; daily FLR hypertrophy 35 cm(3)/day). Duration of the Step 2 operation was 630 min (liver transection time 240 min). Blood loss was 700 cc, with no need for transfusion. The specimen was extracted through a 10-cm Pfannenstiel incision, and pathology revealed a tumor-free resection margin (R0). The patient was discharged on postoperative day 7 without complications (total hospital stay for Step 1 + Step 2: 10 days). CONCLUSIONS: Totally LAPS is a technically feasible and safe procedure. It could provide benefit in selected patients with primarily non-resectable liver cancer, making extreme liver surgery easy and safe in well-selected patients.

Liver transplant is the preferred treatment for hepatocellular carcinoma in patients with cirrhosis, as both neoplastic and cirrhotic liver tissue can be removed. Treatment of recurring neoplasms is a difficult issue, especially in long-term survivors of liver transplant. No consensus has been reached on the treatment of recurrent hepatocellular carcinoma. Although patients with extrahepatic metastases are generally not candidates for local therapy, successful multimodal salvage therapy including resection or ablation can be achieved in liver transplant recipients with local recurrence of hepatocellular carcinoma. Microwave ablation is safe and effective for treating unresectable hepatocellular carcinoma, achieving excellent results in local disease down-staging or as a "bridge" to liver transplant, with no significant differences in local recurrence and complications compared with the more commonly used radiofrequency ablation. A patient with local recurrence of hepatocellular carcinoma 36 months after liver transplant for multifocal hepatocellular carcinoma and cirrhosis due to hepatitis C was successfully treated with laparoscopic microwave ablation without any postoperative complications. The patient is disease free 24 months after microwave ablation.

BACKGROUND: Split liver transplantation is a valuable means of mitigating organ scarcity but requires significant surgical and logistical effort. Ex vivo splitting is associated with prolonged cold ischemia, with potentially negative effects on organ viability. Machine perfusion can mitigate the effects of ischemia-reperfusion injury by restoring cellular energy and improving outcomes. METHODS: We describe a novel technique of full-left/full-right liver splitting, with splitting and reconstruction of the vena cava and middle hepatic vein, with dual arterial and portal hypothermic oxygenated machine perfusion. The accompanying video depicts the main surgical passages, notably the splitting of the vena cava and middle hepatic vein, the parenchymal transection, and the venous reconstruction. RESULTS: The left graft was allocated to a pediatric patient having methylmalonic aciduria, whereas the right graft was allocated to an adult patient affected by hepatocellular carcinoma and cirrhosis. CONCLUSIONS: This technique allows ex situ splitting, counterbalancing prolonged ischemia with the positive effects of hypothermic oxygenated machine perfusion on graft viability. The venous outflow is preserved, safeguarding both grafts from venous congestion; all reconstructions can be performed ex situ, minimizing warm ischemia. Moreover, there is no need for highly skilled surgeons to reach the donor hospital, thereby simplifying logistical aspects.

BACKGROUND AND AIMS: Besides the increased risk of perioperative morbidity, graft failure, and mortality, the majority of PVT are diagnosed at liver transplantation (LT). Improving preoperative management and patient selection may lead to better short-term and long-term outcomes and reduce the risk of a futile LT. The authors aimed to identify predictors of adverse outcomes after LT in patients with nonmalignant portal vein thrombosis (PVT) and improve donor to recipient matching by analyzing the results of the Italian cohort of LT recipients. METHODS: Adult patients who underwent LT in Italy between January 2000 and February 2020 diagnosed with PVT pre-LT or at time of LT were considered eligible for inclusion. Based on a survey encompassing all 26 surgeons participating in the study, a binary composite outcome was defined. Patients were classified as having the composite event if at least one of these conditions occurred: operative time more than 600 min, estimated blood loss greater than 5000 ml, more than 20 ICU days, 90 days mortality, 90 days retransplant. RESULTS: Seven hundred fourteen patients were screened and 698 met the inclusion criteria. The analysis reports the results of 568 patients that fulfilled the criteria to enter the composite outcome analysis.Overall, 156 patients (27.5%) developed the composite outcome. PVT stage 3/4 at transplant and need for any surgical correction of PVT are independent predictors of the composite outcome occurrence. When stratified by PVT grade, overall survival at 1-year ranges from 89.0% with PVT grade 0/1 to 67.4% in patients with PVT grade 3/4 at LT ( P <0.001). Nevertheless, patients with severe PVT can improve their survival when identified risk factors are not present. CONCLUSIONS: Potential LT candidates affected by PVT have a benefit from LT that should be adequately balanced on liver function and type of inflow reconstruction needed to mitigate the incidence of adverse events. Nonetheless, the absence of specific risk factors may improve the outcomes even in patients with PVT grades 3-4.

In the context of spreading interest in textbook outcome (TO) evaluation in different fields, we aimed to investigate an uncharted procedure, that is, laparoscopic microwave ablation (MWA) for hepatocellular carcinoma (HCC). Absence of post-MWA complications, a hospital stay of three days, no mortality nor readmission within 30 days, and complete response of the target lesion at post-MWA CT scan defined TO achievement. Patients treated between January 2014 and March 2021 were retrospectively reviewed, and of the 521 patients eligible for the study, 337 (64.7%) fulfilled all the quality indicators to achieve the TO. The absence of complications was the main limiting factor for accomplishing TO. At multivariable analysis, Child-Pugh B cirrhosis, age of more than 70 years old, three nodules, and MELD score ≥ 15 were associated with decreased probabilities of TO achievement. A score based on these factors was derived from multivariable analysis, and patients were divided into three risk groups for TO achievement. At survival analysis, overall survival (OS) was significantly (p = 0.001) higher in patients who achieved TO than those who did not. Moreover, OS evaluation in the three risk groups showed a trend coherent with TO achievement probability. The present study, having assessed the first TO for laparoscopic MWA for HCC, encourages further broader consensus on its definition and, on its basis, on the development of clinically relevant tools for managing treatment allocation.
RESUMEN
In resected perihilar cholangiocarcinoma (PHC), positive ductal margin (DM) is associated with poor survival. There is currently little knowledge about the impact of positive radial margin (RM) when DM is negative. The aim of this study was to evaluate the incidence and the role of positive RM. Patients who underwent surgery between 2005 and 2017 where retrospectively reviewed and stratified according to margin positivity: an isolated RM-positive group and DM ± RM group. Of the 75 patients identified; 34 (45.3%) had R1 resection and 17 had positive RM alone. Survival was poorer in patients with R1 resection compared to R0 (p = 0.019). After stratification according to margin positivity; R0 patients showed better survival than DM ± RM-positive patients (p = 0.004; MST 43.9 vs. 23.6 months), but comparable to RM-positive patients (p = 0.361; MST 43.9 vs. 39.5 months). Recurrence was higher in DM ± RM group compared to R0 (p = 0.0017; median disease-free survival (DFS) 15 vs. 30 months); but comparable between RM and R0 group (p = 0.39; DFS 20 vs. 30 months). In univariate and multivariate analysis, DM positivity resulted as a negative prognostic factor both for survival and recurrence. In conclusion, positive RM resections appear to have different recurrence patterns and survival rates than positive DM resections.
RESUMEN
This work is the first report of vacuum-assisted closure (VAC) therapy applied as a life-saving surgical treatment for severe acute pancreatitis occurring in a sequential liver- and kidney-transplanted patient who had percutaneous biliary drainage for obstructive "late-onset" jaundice. Surgical exploration with necrosectomy and sequential laparotomies was performed because of increasing intra-abdominal pressure with hemodynamic instability and intra-abdominal multidrug-resistant sepsis, with increasingly difficult abdominal closure. Repeated laparotomies with VAC therapy (applying a continuous negative abdominal pressure) enabled a progressive, successful abdominal decompression, with the clearance of infection and definitive abdominal wound closure. The application of a negative pressure is a novel approach to severe abdominal sepsis and laparostomy management with a view to preventing compartment syndrome and fatal sepsis, and it can lead to complete abdominal wound closure.

Background: In December 2019, an outbreak of pneumonia, caused by a new type of coronavirus, named severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). It quickly spread worldwide, resulting in a pandemic. The clinical manifestations of SARS-CoV-2 range from mild non-specific symptoms to severe pneumonia with organ function damage. In addition, up to 60% of patients have liver impairment or dysfunction, confirmed by several studies by the presence of SARS-CoV-2 in the liver tissue. Methods: We report two cases of symptomatic liver cyst requiring fenestration after recent SARS-CoV-2 infection. Both patients had hospital admission due to documented SARS-CoV-2 infection. Recently, after the infection, they developed symptoms caused by an enlarged hepatic cyst: one had abdominal pain, and the other had jaundice. They underwent surgery after two negative swab tests for SARS-CoV-2. Results: Cystic fluid was sent for microbiological test, and real-time fluorescence polymerase chain reaction COVID-19 nucleic-acid assay of the cyst fluid was found to be negative in both cases. Discussion: Although there are no current data that can document a viral contamination of cystic fluid, there are data that document a hepatotropism of COVID-19 virus. Herein we report that after viral clearance at pharyngeal and nasal swab, there is no evidence of viral load in such potential viral reservoir.
RESUMEN
The development of liver metastases in colon rectal cancer has a strong impact on the overall survival (OS) of the patient, with a 5-year survival rate of 5% with palliative treatment. Surgical resection combined with pharmacological treatment can achieve a 5-year OS rate of 31-58%. However, in only 20% of patients with colon rectal liver metastases (CRLMs), liver resection is feasible. In highly selected patients, recent trials and studies proved that liver transplantation (LT) for non-resectable CRLM is a surgical option with an excellent long-term OS. The paper aims to review the indications and outcome of LT for CRLMs, with a special focus on immunosuppressive therapy and the management of local and extrahepatic recurrence after LT.

Background and aim: Liver transplantation (LT) is a validated treatment for hepatocellular carcinoma (HCC). HCC recurrence occurred between 8 and 20% of patients and lung is the most frequent site. Pulmonary metastases resection (PMR) prolongs survival, however in LT-setting the impact on survival is unclear. To give new lights on this issue, we report the experience of three Italian LT Centers. Methods: All consecutive HCC transplanted patients in three Italian LT Centers, who developed pulmonary metastasis from HCC (PM-HCC), as first metastasis, from 2008 to 2018, were included whenever treated with PMR. Results: Twenty-five patients were enrolled (median age 58 yrs, 84% male, 3% cirrhotics). HCC recurred after 34 months (9-306) since LT and PMR was performed after 2.4 months (0-43.1). A total of 28 PMR (19 single resections; 9 multiple resections; 16 right; 2 left) have been performed on 24 patients while in one case percutaneous microwave ablation (MWA) was preferred. Four patients have been re-operated due to pulmonary HCC-recurrence after surgery. The majority of surgical resection type was wedge resection (26, 89%). Surgical access was: video-assisted thoracic surgery (VATS) in 17 cases (59%); thoracotomy in 11 (38%); MWA in 1 (3%). The 48% of nodule was in right lower lobe. Perioperative in-hospital mortality and 30 days mortality were nil; median surgical time 90 min (50-365); median post-operative overall stay 5 days (2-11). Post-operative ICU treatment was necessary in 1 case (3%) for 3 days; blood transfusions in 2 cases (7%). Overall, 5 complications (2 bleeding; 1 AKI; 1 major cardiac; 1 wound dehiscence) occurred, with an overall complications rate of 23%. Eight (32%) patients died during a follow-up after HCC recurrence of 32 months (7-213): 7 for HCC progression, 1 for severe liver failure due to chronic rejection. The 1 and 5 year cumulative probability of OS from recurrence were 100 and 43% (95%CI 12-74), respectively, with a median OS of 51 months (95%CI 24-78). Conclusion: Selected patients with isolated pulmonary HCC-recurrence after LT and with preserved hepatic function showed that a pulmonary metastasectomy could be efficacious in managing a PM-HCC and could give an opportunity for long-term survival.
RESUMEN
Carbon dioxide embolism during laparoscopic surgery is a serious and life-threatening complication. The overall incidence of embolism during laparoscopic surgery is low (0.15%). Although the potential fatal consequences of this complication are reported in literature, a well-documented report of the effect of massive CO2 embolism during laparoscopic liver resection on cardiovascular, respiratory and encephalographic parameters does not exist. The authors describe a well-documented case of massive carbon dioxide embolism during laparoscopic liver resection suspected by both hemodynamic instability and elevation of EtCO2 and confirmed by arterial blood gas. The surgeon's rapid closure of the vascular breach resulted in an overall improvement of the patient's vital signs without further consequences. Our case report shows the cardiovascular, respiratory and encephalographic effects of a massive carbon dioxide embolism and highlights the importance of a strict cooperation between the surgeon and the anesthesiologist and the importance for a prompt treatment when massive carbon dioxide embolism occurs.
RESUMEN
Liver cancer is the fifth most commonly diagnosed malignancy and the second most frequent cause of cancer death in men worldwide. Amongst liver cancers, hepatocellular carcinoma (HCC) represents the major histological subtype and it is one of the most common malignant human tumors worldwide. Research into the molecular biology of hepatocarcinogenesis has identified several biomarkers, which could provide additional informations in order to better understand the biology of HCC. A large number of biomarkers have been shown to have potential predictive significance and a wide variety of molecular markers have been proven to be excellent diagnostic tools for HCC but it is difficult to characterize HCC with a single biomarker. Thus, signatures of a combination of biomarkers may be more valuable for the diagnosis, staging and prognosis of HCC. Specifically, a correlation of HCC-CSCs phenotype to specific hepatic cancer subtypes and to specific clinical and pathological features has not yet been reported in human liver tumors. In this view we will first discuss the possible sources of liver stem cells and their relation with liver cancer development and we will secondly focus on the prognostic significance of clinical and pathological features of HCC.
RESUMEN
The particular anatomic location of the hepatic caudate lobe between the hilar plate and inferior vena cava means that it is still considered unsuitable for laparoscopic measures and a difficult site even for conventional surgery. Here we describe the first case to be reported in the literature of caudate lobe resection for a single metastasis from breast adenocarcinoma that was completed using an exclusively laparoscopic procedure and a simplified scheme involving the placement of 4 trocars, without any need for conversion or the Pringle maneuver. The patient was 31 years old with a history of radical right mastectomy and chemotherapy. The patient's postoperative course was uneventful and she was discharged 4 days after the surgery. Twelve months on, she is currently alive and disease free.

BACKGROUND: Adrenalectomy represents the definitive treatment in clinically evident Cushing's syndrome; however, the most appropriate treatment for patients with subclinical Cushing's syndrome (SCS) with an adrenal incidentaloma remains controversial. This study was aimed to assess whether adrenalectomy may improve cardiovascular and metabolic impairment and quality of life compared with conservative management. METHODS: Twenty patients with adrenal incidentaloma underwent laparoscopic adrenalectomy for SCS, whereas 15 were managed conservatively. Hormonal laboratory parameters of corticosteroid secretion, arterial blood pressure (BP), glycometabolic profile, and quality of life (by the SF-36 questionnaire) were compared at baseline and the end of follow-up. RESULTS: The 2 groups were equivalent concerning all the examined parameters at baseline. In the operative group, laboratory corticosteroid parameters normalized in all patients but not in the conservative-management group (P < .001). In operated patients, a decrease in BP occurred in 53% of patients, glycometabolic control improved in 50%, and body mass index decreased; in contrast, no improvement or some worsening occurred in the conservative-management group (P < .01). SF-36 evaluation improved in the operative group (P < .05). CONCLUSION: Adrenalectomy can be more beneficial than conservative management in SCS and may achieve remission of laboratory hormonal abnormalities and improve BP, glycemic control, body mass index, and quality of life.

BACKGROUND: Primary hyperaldosteronism may be caused by an aldosterone-producing adenoma (APA), which is correctable by unilateral adrenalectomy or by idiopathic adrenal hyperplasia, a bilateral disease without any indication for surgery. This study sought to assess the prevalence and the results of surgery in unilateral adrenal hyperplasia (UAH). METHODS: The study included 35 patients who underwent unilateral adrenalectomy because of primary hyperaldosteronism after unequivocal successful lateralization by adrenal venous sampling. Demographics, biochemical evaluation, and blood pressure were assessed pre- and postoperatively. Pathology was categorized as APA (isolated adenoma), nodular (multiple micromacronodules), and diffuse UAH (gland thickening without nodules). RESULTS: Pathology revealed 9 APAs and 23 nodular and 3 diffuse UAHs. Patients with APAs and UAHs were statistically similar regarding demographics and preoperative blood pressure levels. Bilateral adrenal involvement was evident at imaging in 10 patients (11% in APA versus 35% in UAH, P = NS). After surgery, biochemical cure of the disease was achieved in all patients; blood pressure levels normalized in 66.6% of patients and ameliorated in 22.2% in APA versus 34.6% and 50% in patients with UAH (P = NS). At a long-term follow-up, only 1 patient with nodular UAH experienced a biochemical recurrence of disease. CONCLUSION: UAH is not rare, sharing the same features of APA. When disease lateralization is confirmed by adrenal venous sampling, unilateral adrenalectomy achieves excellent long-term results.

AIM: To assess B1a cell expression in the rectal mucosa of ulcerative colitis (UC) patients in comparison with healthy controls. METHODS: Rectal mucosa biopsies were collected from 15 UC patients and 17 healthy controls. CD5(+) B cells were analysed by three colour flow cytometry from rectal mucosal samples after mechanical disaggregation by Medimachine(®). Immunohistochemical analysis of B and T lymphocytes was also performed. Correlations between, on the one hand, rectal B1a cell concentrations and, on the other, erythrocyte sedimentation rate and C-reactive protein levels and clinical, endoscopic and histological disease activity indices were evaluated. RESULTS: Rectal B-lymphocyte (CD19(+)/CD45(+)) rate and concentration were higher in UC patients compared with those in healthy controls (47.85% ± 3.12% vs 26.10% ± 3.40%, P = 0.001 and 501 ± 91 cells/mm(2) vs 117 ± 18 cells/mm(2), P < 0.001); Rectal B1a cell density (CD5(+)CD19(+)) was higher in UC patients than in healthy controls (85 ± 15 cells/mm(2) vs 31 ± 6.7 cells/mm(2), P = 0.009). Rectal B1a cell (CD5/CD19(+)) rate correlated inversely with endoscopic classification (Rs = -0.637, P < 0.05). CONCLUSION: B1a lymphocytes seem to be involved in the pathogenesis of UC, however, the role they play in its early phases and in disease activity, have yet to be defined.

BACKGROUND: Late diagnosis of cancer in CD often occurs, and the prognosis is poor. The primary aim of this study was to assess the relationship between clinical presentation and diagnosis of intestinal adenocarcinoma in CD; the secondary aim was to evaluate the timing of cancer occurrence in CD patients. PATIENTS AND METHODS: Medical records of 12 consecutive patients with intestinal adenocarcinoma in CD and of 79 consecutive CD patients undergoing bowel surgery were reviewed. Presentation symptoms were analyzed as possible predictors. Timing of intestinal adenocarcinoma occurrence in patients with CD was analyzed including all the 347 consecutive patients that had undergone surgery for CD in our institute from January 1984 to June 2008. Life table analysis and uni/multivariate analyses were performed. RESULTS: Ten men and two women underwent surgery for intestinal cancer in CD with a median age of 50 years (31-68). Carcinomas were localized in the terminal ileum in four cases, right colon in three, transverse colon in one, sigmoid colon in one, rectum in two, and an anorectal fistula in one. Only three patients were pre-operatively diagnosed with cancer. At multivariate analysis only age (OR 1.057 (95% CI 0.999-1.107), p = 0.05) and obstruction (OR 6.530 (95% CI 1.533-27.806), p = 0.01) significantly predicted cancer diagnosis. The risk rate (RR) for cancer occurrence started to rise at the end of the third decade of life (RR = 0.005). The analysis of risk rate for cancer occurrence during overt CD showed that it is initially high at onset (RR = 0.001) and after two other peaks at 150 months from onset, it began to rise again. The presence of Crohn's colitis was associated to a significant risk of cancer (HR = 4.790, p = 0.009) while the use of 5-ASA resulted to be a protective factor against cancer occurrence (HR = 0.122, p = 0.013). DISCUSSION: In CD, rectal bleeding, the most common alarm symptom for intestinal cancer, is not useful for an early diagnosis. CD patients presenting with an older age and obstruction should be thoroughly investigated to rule out neoplastic lesions. There is probably no safe interval of CD where surveillance for intestinal cancer can be omitted. In the meantime, even in absence of active disease, all CD patients should undergo therapy with 5-ASA.

INTRODUCTION: The aim of this prospective study was to analyze the impact of different surgical techniques on patients undergoing intestinal surgery for Crohn's disease (CD) in terms of recovery, quality of life, and direct and indirect costs. PATIENTS AND METHODS: Forty-seven consecutive patients admitted for intestinal surgery for CD were enrolled in this prospective study. Surgical procedures were evaluated as possible predictors of outcome in terms of disability status (Barthel's Index), quality of life (Cleveland Global Quality of Life score), body image, disease activity (Harvey-Bradshaw Activity Index), and costs (calculated in 2008 Euros). Univariate and multivariate analyses were performed. RESULTS: Significant predictors of a long postoperative hospital stay were the creation of a stoma, postoperative complications, disability status on the third post-operative day, and surgical access (R (2) = 0.59, p < 0.01). Barthel's index at discharge was independently predicted by laparoscopic-assisted approach, ileal CD, and colonic CD (R (2) = 0.53, p < 0.01). The disability status at admission showed to be an independent predictor of quality of life score at follow-up. The overall cost for intestinal surgery for CD was 12,037 (10,117-15,795) euro per patient and stoma creation revealed to be its only predictor (p = 0.006). CONCLUSIONS: Laparoscopy was associated with a shorter postoperative length of stay; stoma creation was associated with a long and expensive postoperative hospital stay, and stricturoplasty was associated with a slower recovery of bowel function.
