Isolated Metachronous Splenic Metastasis from Colon Cancer: Possible Explanations for This Rare Entity
The incidence of splenic metastases secondary to colorectal cancer is very low; these lesions have been more frequently reported as secondary to breast, lung, and ovarian cancer. Splenic metastases are particularly common in melanoma; their incidence has been reported as being as high as 34% at autopsy [1]. Most cases of secondary splenic metastases have been described in patients with tumors of the left colon while only few cases being reported as originating from right colon tumors (Table 1). The finding of a splenic mass in the absence of a history of malignancy suggests a primary lesion (lymphoma, hematoma, etc.), while a history of oncological disease raises the possibility of a secondary lesion [2]
The addition of simvastatin administration to cold storage solution of explanted whole liver grafts for facing ischemia/reperfusion injury in an area with a low rate of deceased donation: a monocentric randomized controlled double-blinded phase 2 study.
BACKGROUND: Liver transplantation is the best treatment for end-stage liver disease. The interruption of the blood supply to the donor liver during cold storage damages the liver, affecting how well the liver will function after transplant. The drug Simvastatin may help to protect donor livers against this damage and improve outcomes for transplant recipients. The aim of this study is to evaluate the benefits of treating the donor liver with Simvastatin compared with the standard transplant procedure.
PATIENT AND METHODS: We propose a prospective, double-blinded, randomized phase 2 study of 2 parallel groups of eligible adult patients. We will compare 3-month, 6-month, and 12-month graft survival after LT, in order to identify a significant relation between the two homogenous groups of LT patients. The two groups only differ by the Simvastatin or placebo administration regimen while following the same procedure, with identical surgical instruments, and medical and nursing skilled staff. To reach these goals, we determined that we needed to recruit 106 patients. This sample size achieves 90% power to detect a difference of 14.6% between the two groups survival using a one-sided binomial test.
DISCUSSION: This trial is designed to confirm the effectiveness of Simvastatin to protect healthy and steatotic livers undergoing cold storage and warm reperfusion before transplantation and to evaluate if the addition of Simvastatin translates into improved graft outcomes.

Case report: Trans-papillary free stenting of the cystic duct and of the common bile duct in a double biliary ducts anastomoses of a right lobe living donor transplantation
Background: One of the major issues related to the living donor liver transplantation recipient outcome is still the
high rate of biliary complication, especially when multiple biliary ducts are present and multiple anastomoses have to
be performed.
Case presentation and conclusion: We report a case of adult-to-adult right lobe living donor liver transplantation
performed for a recipient afected by alcohol-related cirrhosis with MELD score of 17. End-stage liver disease was
complicated by refractory ascites, portal hypertension, small esophageal varices and portal gastropathy, hypersplenism, and abundant right pleural efusion. Here in the attached video we described the adult-to-adult LDLT procedures,
where a right lobe with two biliary ducts draining respectively the right anterior and the right posterior segments
has been transplanted. LDLT required a biliary reconstruction using the native cystic and common bile ducts stented
trans-papillary with two 5- French 6 cm long soft silastic catheter. None major complications were detected during
post-operative clinical courses. Actually, the donor and the recipient are alive and well. The technique we describe in
the video, allow to keep the biliary anastomoses protected and patent without having the risk of creating cholestasis
and the need of invasive additional procedure. No living donor right lobe transplantation should be refused because
of the presence of multiple biliary ducts
How important is the role of iterative liver direct surgery in patients with hepatocellular carcinoma for a transplant center located in an area with a low rate of deceased donation?
Introduction: Hepatocellular carcinoma (HCC) accounts for nearly 90% of primary liver cancers, with estimates of over 1 million people affected by 2025. We aimed to explore the impacting role of an iterative surgical treatment approach in a cohort of HCC patients within the Milan criteria, associated with clinical risk factors for tumor recurrence (RHCC) after liver transplant (LT) and loco-regional therapies (LRT), as well as liver resection (LR) and/or microwave thermal ablation (MWTA). Methods: We retrospectively analyzed our experience performed during an 8-year period between January 2013 and December 2021 in patients treated for HCC, focusing on describing the impact on preoperative end-stage liver disease severity, oncologic staging, tumor characteristics, and surgical treatments. The Cox model was used to evaluate variables that could predict relapse risks. Relapse risk curves were calculated according to the Kaplan-Meier method, and the log-rank test was used to compare them. Results: There were 557 HCC patients treated with a first-line approach of LR and/or LRTs (n = 335) or LT (n = 222). The median age at initial transplantation was 59 versus 68 for those whose first surgical approach was LR and/or LRT. In univariate analysis with the Cox model, nodule size was the single predictor of recurrence of HCC in the posttreatment setting (HR: 1.61, 95% CI: 1.05-2.47, p = 0.030). For the LRT group, we have enlightened the following clinical characteristics as significantly associated with RHCC: hepatitis B virus infection (which has a protective role with HR: 0.34, 95% CI: 0.13-0.94, p = 0.038), number of HCC nodules (HR: 1.54, 95% CI: 1.22-1.94, p < 0.001), size of the largest nodule (HR: 1.06, 95% CI: 1.01-1.12, p = 0.023), serum bilirubin (HR: 1.57, 95% CI: 1.03-2.40, p = 0.038), and international normalized ratio (HR: 16.40, 95% CI: 2.30-118.0, p = 0.006). Among the overall 111 patients with RHCC in the LRT group, 33 were iteratively treated with further curative treatment (12 were treated with LR, two with MWTA, three with a combined LR-MWTA treatment, and 16 underwent LT). Only one of 18 recurrent patients previously treated with LT underwent LR. For these RHCC patients, multivariable analysis showed the protective roles of LT for primary RHCC after IDLS (HR: 0.06, 95% CI: 0.01-0.36, p = 0.002), of the time relapsed between the first and second IDLS treatments (HR: 0.97, 95% CI: 0.94-0.99, p = 0.044), and the impact of previous minimally invasive treatment (HR: 0.28, 95% CI: 0.08-1.00, p = 0.051). Conclusion: The coexistence of RHCC with underlying cirrhosis increases the complexity of assessing the net health benefit of ILDS before LT. Minimally invasive surgical therapies and time to HCC relapse should be considered an outcome in randomized clinical trials because they have a relevant impact on tumor-free survival
Donor Simvastatin Treatment Is Safe and Might Improve Outcomes After Liver Transplantation: A Randomized Clinical Trial.
BACKGROUND
The current curative approaches for ischemia/reperfusion injury on liver transplantation are still under debate for their safety and efficacy in patients with end-stage liver disease. We present the SIMVA statin donor treatment before Liver Transplants study.
METHODS
SIMVA statin donor treatment before Liver Transplants is a monocentric, double-blind, randomized, prospective tial aiming to compare the safety and efficacy of preoperative brain-dead donors' treatment with the intragastric administration of 80 mg of simvastatin on liver transplant recipient outcomes in a real-life setting. Primary aim was incidence of patient and graft survival at 90 and 180 d post-transplant; secondary end-points were severe complications.
RESULTS
The trial enrolled 58 adult patients (18-65 y old). The minimum follow-up was 6 mo. No patient or graft was lost at 90 or 180 d in the experimental group (n = 28), whereas patient/graft survival were 93.1% (P = 0.016) and 89.66% (P = 0.080) at 90 d and 86.21% (P = 0.041) and 86.2% (P = 0.041) at 180 d in the control group (n = 29). The percentage of patients with severe complications (Clavien-Dindo ≥IIIb) was higher in the control group, 55.2% versus 25.0% in the experimental group (P = 0.0307). The only significant difference in liver tests was a significantly higher gamma-glutamyl transferase and alkaline phosphatase at 15 d (P = 0.017), (P = 0.015) in the simvastatin group.
CONCLUSIONS
Donor simvastatin treatment is safe, and may significantly improve early graft and patient survival after liver transplantation, although further research is mandatory
Protective benefit of minimally invasive liver surgery for hepatocellular carcinoma prior to transplant
Aim: The purpose of this study is to assess the benefit of laparoscopic liver resection (LLR) for hepatocellular carcinoma (HCC) given recurrence and future need for liver transplantation (LT). Methods: Data on liver resections were gathered from the Istituto di Ricovero e Cura a Carattere Scientifico-Istituto Mediterraneo per i Trapianti e Terapie ad alta specializzazione (IRCCS-ISMETT) from 2003-2021. A retrospective analysis of 1408 consecutive adult patients who had a liver resection was performed with categorization based on the underlying disease process. A sub-analysis studied the 291 patients who had an LLR with an intention to transplant approach after LLR. Results: From 2012 to 2020, ISMETT’s mean annual LLR rate was 45%. Data suggests that a laparoscopic approach to iterative surgical treatment for HCC has demonstrated protective benefits. Compared to open surgery or LT, LLR is protective against the risk of de-listing, post-transplant patient death, tumor recurrence, adhesions, and bleeding in a cirrhotic patient. Kaplan Meier’s analysis showed no difference between post-LT survival curves for those with prior open abdominal surgery or LLR (P = 0.658). Conclusion: Laparoscopic surgery has important protective advantages over laparotomy surgery for the surgical treatment of HCC, particularly since treatment is not always curative. LLR can be considered a bridge therapy for transplantation, ensuring less crowding of waiting lists, a desirable condition in areas of donor storage

The value of total thyroidectomy as the definitive treatment for Graves’ disease: A single centre experience of 594 cases
Purpose: Thyroidectomy is the preferred approach as the definitive treatment for Graves’ disease. The outcomes for total thyroidectomy in a large series of 594 patients, who were observed in the last decade, will be presented in this study. Methods: The study concerned a retrospective review of 594 patients, undergoing a total thyroidectomy for Graves’ disease. The incidence of complications and outcomes on hyperthyroidism and correlated symptoms resolution were also evaluated. Results: The mean age of the patients was of 44.7 ± 12.7 years and 456 patients (76.7%) were females. The mean gland weight was 67.3 ± 10.8 g (range: 20–350 g) and, in 397 patients (66.8%), the gland weighed >40 g. The mean operative time was 125 ± 23.1 min (range: 65–212 min). Temporary and permanent hypocalcaemia developed in 241 (40.6%) and 3 patients (0.5%), respectively. Temporary and permanent recurrent laryngeal nerve palsy were recorded in 31 (5.2%) and 1 patients (0.16%) respectively. No patient developed a thyroid storm. On multivariate analysis, patient age ≤50 years (Odds ratio: 1; 95% Confidence Interval: 0.843–0.901) and thyroid weight >40 g (Odds ratio: 1; 95%, Confidence Interval: 0.852–0.974), were mainly associated with the occurrence of complications. Conclusion: This high-volume surgeon experience demonstrates that total thyroidectomy is a safe and effective treatment for Graves’ disease. It is associated with a very low incidence rate of post-operative complications, most of which are transitory; therefore, it offers a rapid and definitive control of hyperthyroidism and its related symptoms
Axillary Nodal Burden in Breast Cancer Patients With Pre-operative Fine Needle Aspiration-proven Positive Lymph Nodes Compared to Those With Positive Sentinel Nodes
BACKGROUND/AIM: Recent years have seen a considerable shift to a more conservative management of the axilla in patients with positive axillary sentinel lymph nodes. The aim of this study was to determine whether some breast cancer patients with a preoperative ultrasound-guided needle aspiration biopsy proven positive node could potentially be spared an axillary lymph node dissection according to the ACOSOG Z0011 trial criteria.
PATIENTS AND METHODS: A retrospective review was performed involving 623 breast cancer patients who underwent axillary lymph node dissection after either ultrasound-guided needle aspiration biopsy proven positive node or sentinel lymph node biopsy.
RESULTS: Patients with fine needle aspiration biopsy-proven positive node had worse prognosis and a higher nodal burden (6.7 vs 1.9 nodes, p<0.001), compared to those with positive sentinel lymph nodes.
CONCLUSION: Patients with an ultrasound guided needle aspiration biopsy proven positive node are more likely to have tumor with more aggressive pathological characteristics and a higher nodal burden than those with a positive sentinel lymph node biopsy
