Background The use of Indocyanine Green (ICG) fluorescence is a well-established technique in colorectal surgery for the evaluation of bowel stump perfusion. However there is still no definitive acceptance, except intraoperative macroscopic evidence, with reference to the incidence of anastomotic leakage (AL). The objective of this study is to confirm the same efficacy and reliability of ICG in elective colorectal surgery, and emergency cases, which would be more exposed to complications related to inadequate vascularization.Methods From January 2019 to June 2020, we used ICG to evaluate the perfusion of colonicstumps before and after packaging the anastomosis in right and left hemicolectomy, rectal resection and Hartmann’s reversals.Results A total of 40 patients underwent surgery, 21 (52.50%) had benign pathology and 19 (47.50%) exhibited malignant neoplasia. 13 (32.50%) were emergency surgeries and 27 (67.50%) were planned elective surgeries. In almost all cases, the postoperative course was regular, in only 1 (2.5%) case of TaTME there was an AL. Other complications were not related to the anastomosis, but some validated the excellent perfusion despite episodes of prolonged acute ischemia due to postoperative hemorrhage. Data were finally compared to a control group of 39 patients where the ICG fluorescence was not used.Conclusions The study confirms the validity of the use of ICG fluorescence as a method for intraoperative assessment of bowel perfusion even in emergency conditions and in acute postoperative hemorrhage, detecting an incidence of 2.5% (1 case out of 40) of AL. It’s evident that to validate our results, further randomized studies on a larger data set are required. It would also be beneficial to evaluate quantitatively the fluorescence between the mucous and serous layer, to confirm the reduction of AL rate, the better evaluation of bowel perfusion and, especially in emergency surgeries, the potential reduction of further operations.

International audience; Background. Diffuse large B-cell lymphoma (DLBCL) is the most common subtype of non -Hodgkin lymphoma in the posttransplant setting. Treatment is based on chemotherapy; surgery is still debated and should be performed in very select cases. Methods. We observed 2 patients out of 300 who underwent lung transplantation in the Nouvel Hopital Civil between 2013 and 2019 with primary hepatic lymphoma. Chemotherapy with a rituximab-cyclophosphamide, hydroxydaunorubicin, vincristine, prednisone protocol was performed in all patients. Mycophenolate mofetil was interrupted before treatment, and everolimus was introduced after chemotherapy by associating tacrolimus withdrawal. Results. One patient showed complete remission; after 7 years, no recurrence has been noticed. The second is still undergoing chemotherapy with no signs of disease progression. Conclusions. DLBCL risk is higher in solid organ transplant recipients than in the general population. Primary hepatic lymphoma diagnosis is often difficult and based on histologic findings after initial clinical and radiological suspicion of primary or secondary liver neoplasia. Diagnosis is challenging because no clinical, radiological, or biological features exist. Biopsy is always indicated for histologic confirmation. Chemotherapy is the mainstay of therapy, but surgery may be indicated in very select patients.

Purpose The differential diagnosis between primary adenocarcinoma of the pancreas head and distal cholangiocarcinoma remains a clinical challenge. Recent studies have shown important differences in terms of survival between these tumors. Therefore, different treatments should be considered, but the preoperative histological diagnosis is still difficult. Aim of this study is to create a preoperative diagnostic score for differential diagnosis between primary pancreatic adenocarcinoma and primary distal cholangiocarcinoma. Methods One hundred eighty consecutive patients who underwent pancreaticoduodenectomy at Sapienza University of Rome from January 2010 to December 2019 were retrospectively analyzed. Inclusion criteria were pancreatic or biliary histologic origin obtained by definitive postoperative histological examination. Exclusion criteria were diagnosis of ampullary carcinoma, non-ampullary duodenal adenocarcinoma, pancreatic metastasis, and benign disease. One hundred one patients were considered eligible for the retrospective study. Preoperative biological, clinical, and radiological parameters were considered. Results CRP > 10 mg/dL (p = 0.001), modified Glasgow Prognostic Score 2 (p = 0.002), albumin p = 0.05), CA 19-9 > 230 U/mL (p = 0.001), and Wirsung diameter > 3 mm (p < 0.001) were significant at univariate logistic analysis. Multivariate logistic analysis has shown that parameters independently associated with primary pancreatic adenocarcinoma were CRP > 10 mg/dL (p = 0.012), CA 19-9 > 230 U/mL (p = 0.043), and diameter of the Wirsung > 3 mm (p = 0.005). Through these parameters, a diagnostic score has been developed to predict a primary pancreatic adenocarcinoma when > 1 and a primary distal cholangiocarcinoma when Conclusion This feasible and low-cost diagnostic score could have a potential impact to differentiate pancreatic cancer histologic origin and to improve target therapeutic strategy.

Background/Aim: Survival of patients with pancreatic cancer remains poor despite improvements in therapeutic strategies. This study aims to create a novel preoperative score to predict prognosis in patients with tumors of the pancreaticobiliary head. Patients and Methods: Data on 190 patients who underwent to pancreaticoduodenectomy at Sapienza University of Rome from January 2010 to December 2018 were retrospectively analyzed. After exclusion criteria, 101 patients were considered eligible for retrospective study. Preoperative biological, clinical and radiological parameters were considered. Results: Pancreatic ductal adenocarcinoma [hazard ratio (HR)=1.995, 95% confidence intervaI (CI)=1.1-3.3; p=0.01], carbohydrate antigen 19.9 (CA 19.9) >230 U/ml (HR=2.414, 95% CI=2.4-1.5, p3 mm (HR=1.592, 95% CI=1.5-0.9; p=0.08) were the only parameters associated with poor prognosis. Through these parameters, a prognostic score (PHT score) was developed which predicted worst survival when exceeding 2 and better survival when ≤2. Conclusion: The PHT score may have a potential impact on predicting overall survival and consequently modulate the timing and type of treatment (up-front surgery vs. neoadjuvant therapy) patients are offered.

PURPOSE The hepato-mesenteric trunk is an extremely rare condition in which the common hepatic artery (CHA) originates from the superior mesenteric artery (SMA). Usually, CHA passes behind the head of the pancreas. A systematic review was performed to provide guidelines for the perioperative management of patients with this anatomical variation who underwent a pancreaticoduodenectomy (PD). A case report was also included. METHODS A systematic search of the literature was conducted and the manuscript was structured following point-by-point the PRISMA guidelines. The risk of bias within individual studies was assessed using the Joanna Briggs Institute Critical Appraisal Checklist tools. Case report was structured according to the CARE guidelines. RESULTS After an initial selection of 141 titles, 9 articles were included in the study (n���=���10 patients). A postoperative surgical complication which required a reintervention occurred only one time. In four patients, CHA had a posterior position relative to pancreas, while in three cases, it was anterior. The remaining three patients had an intrapancreatic course. The CHA was resected in two patients, with an end-to-end reconstruction or using the splenic artery stump. In only three patients, a preoperative multidisciplinary presentation was performed and in four cases, the CHA variation was not described by radiologists in formal CT-scan reports. CONCLUSION Although there are no definitive guidelines, improvements in the preoperative knowledge of such a rare anatomical variation may ensure better postoperative outcomes, avoiding intraoperative accidents and life-threatening postoperative complications.

In right-sided colon cancer surgery, currently there is a great deal of discussion and debate regarding complete mesocolic excision (CME) versus conventional right hemicolectomy (CRH) on postoperative outcomes and oncological results. Our aim was to perform a systematic review of the short- and long-term outcomes of CME to standardize surgical approach in patients with right-sided colon cancer. A systematic review was performed examining available data on randomized and non-randomized studies evaluating the role of CME and D3 lymphadenectomy in the treatment of right-sided colon cancer, in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) standards. After literature search, 919 studies have been recorded, 110 studies underwent full-text reviews and 30 studies met inclusion criteria. The total number of CME procedures was 5931. Postoperative complications was reported in 28 studies with pooled overall complications of 1.88% for CME surgery. Six studies reported 0% of overall postoperative complications and they demonstrated a low incidence of complications following CME procedure. Anastomotic leak was reported in 27 studies with pooled proportion of 0.92% after CME resections. There were 16 papers reporting overall survival following CME procedure, with a mean of 85% of patients survived at 5 years. Mean 5-year overall survival was 93.05% in stage I patients, 89.76% in stage II patients and 79.65% in stage III patients. Local and distant recurrence were included in 21 studies, reporting tumor recurrence rate of 12.25% following CME. 5-year tumor recurrence was 5.8% in stage I patients, 7.68% in stage II patients and 15.69% in stage III patients. CME does not increase the risk of postoperative complications and significantly improves the long-term oncological impact. Prospective multicentre studies results are needed to verify if CME could be considered standard surgery for right colon cancer.

Background Sickle cell disease is a group of autosomal recessive disorders characterised by haemolytic anaemia. Liver is one of the most affected organs, ranging from liver tests alterations to acute liver failure for which liver transplantation is the only life-saving treatment. Methods This study aims to make a systematic review of the current literature to evaluate indications, timing, and results of liver transplantation for patients affected by SCD. Results Twenty-nine patients in total were reported worldwide until 2018, the average patient age is 28.7 (0.42–56), all patients have a pre-transplant diagnosis of SCD. Cirrhosis at transplantation was present in six-teen (n = 16, 55.1%) patients. In ten patients (n = 10, 34.5%), acute liver failure arises from healthy liver and presented sickle cell intrahepatic cholestasis. Eleven patients (n = 11, 39.2%) died, three (n = 3, 10.7%) in the first postoperative month, and seven (n = 7, 25%) in the first year. Mean follow-up was 27 months (range: 7–96), one-year overall survival was 48.7%. Discussion Liver transplantation for SCD has been increasingly reported with encouraging results. Indications are presently reserved for acute liver failure arising both in healthy liver and end-stage liver disease.

Background Intrapancreatic accessory spleen (IPAS) is an uncommon finding of pancreatic mass. Differential diagnosis with pancreatic tumor, especially with non-functional neuroendocrine tumor (NF-NET), may be very hard and sometimes it entails unnecessary surgery. A combination of CT scan, MRI, and nuclear medicine can confirm the diagnosis of IPAS. 68-Ga-Dotatoc PET/CT is the gold standard in NET diagnosis and it can allow to distinguish between IPAS and NET. Case presentation A 69-year-old man was admitted to our hospital for an incidental nodule in the tail of the pancreas with focal uptake of 68-Ga-dotatate at PET/CT. NET was suspected and open distal splenopancreatectomy was performed. Pathologic examination revealed an IPAS. Conclusion This is the second IPAS case in which a positive 68Ga-Dotatoc uptake led to a false diagnosis of pancreatic NET. Here is a proposal of a literature review.
