Accreditation for colorectal cancer surgery in Italy. Preliminary results of a new program in a district hospital.

Accreditation for colorectal (CR) cancer surgery has become a major issue in Italy. This study aimed to analyze the early results of a newly structured program for the treatment of CR cancer in a rural district hospital. Between 2017 and 2018, a total of 214 consecutive patients underwent a CR procedure for malignancy. There were 113 men and 101 women of a mean age of 74 years. Primary CR adenocarcinoma was diagnosed in 210 patients (98%). The incidence of stage I, II, III, and IV disease was 26%, 31%, 24%, and 19% respectively. Hospital volume increased tenfold compared to previous years. Anatomical resection was performed in 204 patients. Right-sided resection and resection of the transverse colon or left angle were performed in 76 (37%) and 14 (7%) patients, respectively. A restorative left sided CR resection was performed in 80 patients (39%), whereas Hartmann procedure and Miles abdominal-perineal resection were performed in 27 (13%) and 6 (3%) patients, respectively. Total colectomy with ileorectal anastomosis was performed in one patient, and two more patients underwent atypical resection. Emergency cecostomy was performed in 15 patients and a colic endoprosthesis was implanted in one patient for obstruction and seven underwent resection afterwards. Laparoscopic resection was performed in 118 patients (57.8%), and the conversion rate was 2%. Overall morbidity, reintervention, and mortality rates were 24.6%, 3,7%, and 3.2%, respectively. The incidence of AL was 4.6%, and two patients died of the consequences of it after right hemicolectomy. Five more elderly patients died for non-surgical related medical complications. The median hospital stay was ten days, and early unplanned readmission rate was 2%. Hospital and surgeon requirements, in terms of minimum volume, organization, and surgical outcome were fulfilled. A rural district hospital can become a tertiary referral center for the surrounding districts without imposing unreasonable travel burdens for patients. CR surgery represents a capital investment for the hospital administration since it shows the effectiveness and quality of care.

The role of minimally invasive surgery in the treatment of cholangiocarcinoma.

Cholangiocarcinoma (CC) is the second most common type of primary liver cancer after hepatocellular carcinoma. Surgical resection is considered the only curative treatment for CC. In general, laparoscopic liver surgery (LLS) is associated with improved short-term outcomes without compromising the long-term oncological outcome. However, the role of LLS in the treatment of CC is not yet well established. In addition, CC may arise in any tract of the biliary tree, thus requiring different types of treatment, including pancreatectomies and extrahepatic bile duct resections. This review presents and discusses the state of the art in the laparoscopic and robotic surgical treatment of all types of CC. An electronic search was performed to identify all studies dealing with laparoscopic or robotic surgery and cholangiocarcinoma. Laparoscopic resection in patients with intrahepatic CC (ICC) is feasible and safe. Regarding oncologic adequacy, as R0 resections, depth of margins, and long-term overall and disease-free survival, laparoscopy is comparable to open procedures for ICC. An adequate patient selection is required to obtain optimal results. Use of laparoscopy in perihilar CC (PHC) has not gained popularity. Further studies are still needed to confirm the benefit of this approach over conventional surgery for PHC. Laparoscopic pancreaticoduodenectomy for distal CC (DCC) represents one of the most advanced abdominal operations owing to the necessity of a complex dissection and reconstruction and has also had small widespread so far. Minimally invasive surgery seems feasible and safe especially for ICC. Laparoscopy for PHC is technically challenging notably for the caudate lobectomy. Not least as for the LLR, the robotic approach for DCC appears technically achievable in selected patients.

Leiomyosarcoma of the inferior vena cava.

BACKGROUND: Leiomyosarcoma (LMS) of the inferior vena cava (IVC) is a rare tumor with poor prognosis. Optimal treatment includes complete resection of the malignant lesion. METHODS: From 1997 to 2013, eight patients underwent surgery in our department for IVC LMS. LMS was considered to arise from the IVC if the tumor presented intraluminal development or if complete resection (R0) required removal of part of the IVC with an extraluminal mass. RESULTS: There were two grade 1 tumors (25%), four grade 2 (50%) and two grade 3 (25%). The median length of stay was 16 days and there were no peri-operative deaths. Median of follow-up was 56 months and mean overall survival was 120 months. Mean 3-year survival rate was 87.5%. Six patients (75%) developed a local recurrence. Four patients died from disease progression. Two patients underwent to surgery for recurrence. CONCLUSION: IVC LMS have a poor prognosis if surgical resection cannot be achieved. Long-term survival is related to an extensive surgery, in the event of recurrence, surgery should again be proposed and may be effective for controlling disease progression, possibly improving survival.

Hepatoblastoma in a 14 month-old female.

Hepatoblastoma (HB) is the most common malignant liver tumor in children. Complete surgical resection is the best treatment choice with a good prognosis in most cases. We present the case of a 14 month-old female patient was admitted to the pediatric surgery unit due to an abdominal mass localized in the right upper quadrant. The diagnosis retained was hepatoblastoma, so the patient underwent preoperative chemotherapy. The final size of the tumor permitted a complete surgical resection through a right subcostal incision enlarged to the left. Hepatoblastoma is the most common malignant liver tumor in children, more frequent in male than in female and typically presenting before 3 years of age as an abdominal mass found accidentally. Recent treatment strategies, consisting of chemotherapy combined with extensive surgery and in extreme cases liver transplantation, have improved the prognosis during the last years although HB's etiology and management are still subjects of debate.

Intra-arterial yttrium-90 radioembolization combined with systemic chemotherapy is a promising method for downstaging unresectable huge intrahepatic cholangiocarcinoma to surgical treatment.

PURPOSE: To evaluate the downstaging efficacy of yttrium-90 radioembolization (Ytt-90)-associated with chemotherapy and the results of surgery for initially unresectable huge intrahepatic cholangiocarcinoma (ICC). METHODS: Between January 2008 and October 2013, unresectable ICC were treated with chemotherapy and Ytt-90. Patients with unique tumors localized to noncirrhotic livers and without extrahepatic metastasis were considered to be potentially resectable and were evaluated every 2 months for possible secondary resection. RESULTS: Forty-five patients were treated for unresectable ICCs; ten had potentially resectable tumors, and eight underwent surgery. Initial unresectability was due to the involvement of the hepatic veins or portal vein of the future liver remnant in seven and one cases, respectively. Preoperative treatment induced significant decreases in tumor volume (295 vs. 168 ml, p = 0.02) and allowed for R0 resection in all cases. Three patients (37.5 %) had Clavien-Dindo grade three or higher complications, including two postoperative deaths. The median follow-ups were 15.6 [range 4-40.7] months after medical treatment initiation and 7.2 [0.13-36.4] months after surgery. At the end of the study period, five patients were still alive, with one patient still alive 40 months after medical treatment initiation (36.4 months after surgery); two patients experienced recurrences. CONCLUSIONS: For initially unresectable huge ICCs, chemotherapy with Ytt-90 radioembolization is an effective downstaging method that allows for secondary resectability.

Inguinal lymphadenectomy for stage III melanoma: a comparative study of two surgical approaches at the onset of lymphoedema.

INTRODUCTION: When sentinel lymph node is positive for metastasis (exclusion for micro-metastasis) and in cases of palpable adenopathy, a lymphadenectomy should be performed. Many incisional surgical approach have been described in literature. We perform two type of incision (vertical with skin excision and transversal) for inguinal lymphadenectomy. The aim of this study was to compare post-operative morbidity between these two approach in cases of Stage III Melanoma. We analysed chronic lymphoedeme, skin necrosis, wound dehiscence, wound infection and seroma rates between the two techniques. METHODS: From April 2000 to February 2012 fifty-three patients underwent to inguinal lymphadenectomy for Stage III melanoma at CHU of Rennes. Patients were stratified in 2 groups according to the surgical approach, group 1 with a vertical incision with skin excision and group 2 with a transverse incision. RESULTS: Chronic lymphoedema rate for group 1 was 37.04% and for group 2 rate was 26.92%, this complication was lower un group 2 but no significant difference was observed (p = 0.558). Skin necrosis (p = 0.235), wound dehiscence (p = 1.000), wound infection (p = 0.236) and seroma (p = 0.757) were not significantly different. Two cases of skin necrosis were observed in group 2 (7.69%) and none in group 1. CONCLUSION: We do not found significant difference for chronic lymphoedema between these two approach. However, we had less lymphoedema with the transversal technique which has the advantage to reduce the skin suffering when external iliac lymphadenectomy dissection is necessary in addition to the inguinal lymphadenectomy.

The ALPPS procedure for hepatocellular carcinoma.

BACKGROUND: The main limiting factor to major hepatic resections is the amount of the future liver remnant (FLR). Associating Liver Partition with Portal Vein Ligation for Staged Hepatectomy (ALPPS) is a procedure which induces a rapid hypertrophy of the FLR in patients with non-resectable liver tumours. METHODS: ALPPS is a surgical technique of in-situ splitting of the liver along the main portal scissura or the right side of the falciform ligament, in association with portal vein ligation in order to induce a rapid hypertrophy of the left FLR. RESULTS: The median FLR volume increase was 18.7% within one week after the first step and 38.6% after the second step. At the first step the median operating time was 300 min, blood transfusions were not required in any case, median blood loss was 150 cc. At the second step median operating time was 180 min, median blood loss was 50 cc, none of the patients required intra-operative blood. All patients are alive at a median follow up of 9 months. CONCLUSIONS: This novel strategy seems to be feasible even in the context of a cirrhotic liver, and demonstrates the capacity to reach a sufficient FLR within a shorter interval of time.

Expanded criteria for hepatocellular carcinoma after liver transplantation: a 20-year evolution.

BACKGROUND/AIM: Milan Criteria (MC) consent excellent survivals for hepatocellular carcinoma (HCC) after liver transplantation (LT). However, several new expanded criteria were proposed, with the intent to increase the HCC patients eligible for LT, maintaining acceptable recurrence rates. The aim of the present study was to analyze a cohort of HCC patients, evaluating the evolutions in its management during the last 20 years and comparing the disease-free survivals among three different periods. METHODOLOGY: HCC patients (n = 122) were transplanted and stratified in three periods: 1st (1988-1998, liberal selection), 2nd (1999-2003, use of MC) and 3rd (2004-2008, use of UCSF criteria). The three periods were analyzed and their survivals were compared. RESULTS: Statistical differences were reported at univariate analysis regarding to both dimensional (total tumor diameter) and biological (alpha feto-protein, microvascular invasion) HCC features. Comparing the 5-year survival rates, a progressive increase was observed in the three periods (62.6%, 87.9% and 88.4%, respectively), with a significant difference between 1st and the second periods (p = 0.008). CONCLUSIONS: In our experience, use of UCSF criteria is safe, with a contemporaneous increased number of transplants and better survivals. Introduction of new selection criteria, also based on biological features, is on the way.

Hepatic resection for giant haemangioma in a patient with a contemporaneous adult polycystic liver disease.

Hepatic resection for giant haemangioma in a patient with a contemporaneous adult polycystic liver disease. According to Gigot classification, and to the characteristics of haemangioma surgery in these patients can be considered safe. We report the case of a 55 year-old man affected by an adult polycystic liver disease (PCLD) and a contemporaneous symptomatic haemangioma of the III segment. At the preoperative imaging scans, APCLD was classified in a type II grading according to Gigot classification. The patient underwent surgery: a wedge resection of the III segment with the exportation of the haemangioma and a fenestration of a large cyst placed in the VIII segment were performed. Post-operative course was regular and the patient was discharged uneventfully in post-operative 9th day, with a total regress of the initial symptoms. APCLD and haemangioma are two benign conditions that do not require surgery except if they cause important symptoms, such as pain. The good clinical conditions of the patient, the moderate gravity of the APCLD and the particular exofitic localisation of the cavernous haemangioma gave us the possibility to make a safe surgery for the patient. To the best of our knowledge, this is the first case reported in literature in which a liver resection for haemangioma in patient with APCLD was performed. In conclusion, liver resection for haemangioma is not contraindicated, mainly if it is symptomatic, even in the contemporaneous presence of an APCLD.

Later diagnosed with a neuroendocrine tumor, case report of a 60-year-old.

Neuroendocrine tumours of the colon and rectum are infrequent. Clinical manifestations are not different from standard adenocarcinoma. Symptoms are non specific; the most common are abdominal pain, nausea and vomiting, weight loss and gastrointestinal blood loss. We report an advanced case of transverse colon neuroendocrine carcinoma with multiple metastasis. When these tumours are diagnosed, they have distance disease related to a poor prognosis for the patient. Surgery is the treatment that can offer a greater chance of survival to these patients.

Glasgow coma score and tumor necrosis factor α as predictive criteria for initial poor graft function.

Initial poor graft function (IPGF) is a major factor influencing the clinical outcome after liver transplantation (LT), but there is no reliable method to assess and predict graft dysfunction. To help clinicians determine prognosis in the early postoperative period, individual parameters and complex scoring systems have been suggested, but most of them are inaccurate because of the multifactorial nature of transplantation courses. Therefore, the aim of our study was to retrospectively evaluate predictive criteria for retransplantation. Forty-two patients were enrolled in this study: 18 who experienced primary non-function (PNF) and 24 with delayed graft function (DGF). All of the patients were treated with the Molecular Adsorbent Recirculating System (MARS). They were into 3 subgroups: patients who survived without LT (n = 20; 47.7%); patients who underwent LT (n = 16; 37%), and patients who died before transplantation (n = 6; 14%). Stepwise multivariable logistic regression analysis was performed with the intent to find the risk factors for LT or death after MARS treatment (second analysis). Receiver operating characteristic (ROC) curves were performed on significant variables in the logistic regression model with the intent to individually predict variables for LT or death. After a stepwise multivariable logistic regression analysis enrolling all of the previously reported features only 2 variables, tumor necrosis factor (TFN)-α and Glasgow coma score (GCS) score, were statistically significant. TNF-α was an unique independent risk factor for retransplantation or death after MARS treatment (odds ratio [OR] 1.235; P = .013). Conversely, GCS score was protective against retransplantation or death (OR 0.150; P = .003). Starting from these assumptions, a predictive model was created using these 2 variables. On ROC analysis, the combined score showed an area under the curve greater than that of the 2 variables considered separately. Validating these results with a larger number of patients, we considered these 2 factors as subjective parameters to determine outcomes and the difference between PNF and DGF.

An unusual case of hepatic carcinosarcoma.

We report a rare case of a hepatic carcinosarcoma with rabdomyosarcomatous differentiation in its sarcomatous component. A 71-year old Caucasian female patient underwent a liver resection for a 4-cm lesion developed on an underlying HCV-related cirrhosis. Post-operative course was uneventful and the patient was discharged 5 days after surgery. At pathology, the tumor presented the features of hepatocellular carcinoma and rhabdomyosarcoma Three months later the patient experienced a liver recurrence, dying 2 months later for systemic disease. The reported case presents several peculiarities, i.e. the female gender, the HCV-related cirrhotic status, and the European origin of the patient. However, the outcome of our case confirms that this neoplasm pursues a highly aggressive course with poor prognosis.

Survival after kidney transplantation does not differ with 50-59- or over 60-year-old expanded-criteria donors.

BACKGROUND: Use of expanded-criteria donors (ECDs) for kidney transplantation has progressively increased in the past years with the intent to improve the number of available grafts. However, it is still uncertain if ECD kidneys have worse survivals than standard-criteria ones. The aim of this study was to retrospectively analyze a cohort of ECD patients comparing the 2 subgroups of 50-59- and >60-year-old donors in terms of donor, recipient, and transplant features and survival rates. METHODS: Ninety-one cases were analyzed. The cohort was stratified into 2 subgroups according to donor age: group 1, age 50-59 years (n=26); and group 2, age ≥60 years (n=67). RESULTS: Group 2 represented older donors and a higher percentage of donors with a previous history of hypertension. In Group 1, preharvest creatinine values showed higher results. No difference was detected regarding patient and graft survivals, with 5-year survival rates of 92.3% versus 86.7%, and 70.8% versus 69.8%, respectively. The best way to select the donors is still under debate. In our experience, a biopsy-driven selection was performed exclusively for group 2 ECDs. Considering the similar survivals obtained, we speculated that an accurate biopsy-based selection of older grafts allows one to avoid "bad" donors from the allocation system, thereby obtaining improved survival results. CONCLUSIONS: Biopsy-driven pretransplantation selection appears to be the main system to optimize results, to achieve outcomes similar to nonbiopsied younger donors. Routine biopsies also in the younger subgroup of ECD may achieve a further improvement in survival.

Clinical results of treatment of postsurgical endotoxin-mediated sepsis with polymyxin-B direct hemoperfusion.

We evaluated the possibility of preventing the evolution of endotoxin-mediated sepsis in severe septic shock using early treatment of critical endotoxemia with polymyxin-B direct hemoperfusion (PMX-DHP). Thirty-eight postsurgical patients who fulfilled at least 2 criteria for systemic inflammatory response syndrome were stratified on the basis of the value of the endotoxin activity assay. Seventeen patients who demonstrated high risk of endotoxin activity (>or=0.6) received standard therapy plus PMX-DHP every 24 hours to lower the endotoxin activity level to less than 0.4, and the remaining 21 patients with endotoxin activity levels less than 0.6 received standard therapy only. Seven patients required 2 courses of PMX-DHP therapy, 8 required 3 courses, and 2 required 4 courses. After treatment, mean arterial pressure increased, from 69.00 mm Hg to 81.35 mm Hg (P < .01); heart rate decreased, from 105.40 bpm to 78.12 bpm (P < .01); white blood cell count decreased, from 20,700 cells/mm(3) to 9740 cells/mm(3) (P < .01); arterial oxygen tension-fraction of inspired oxygen ratio increased, from 273.82 to 305.82 (P < .01); and Sequential Organ Failure Assessment score decreased, from 7 to 4 (P < .01). Length of stay was longer for transplant recipients (16 days) than for other surgical patients (8(1/2) days). All patients survived to 28-day follow-up, and 15 of 16 patients (94%) had survived at 60-day follow-up. Despite the small number of patients included in the study, the encouraging results suggest that PMX-DHP is a useful therapeutic strategy for lowering sepsis-related mortality.

Early urine output predicts graft survival after kidney transplantation.

BACKGROUND: In kidney transplantations, the identification of early postoperative parameters with high predictive power for the development of late allograft dysfunction has important implications for clinical practice. This study sought to determine these parameters in a single-center cohort. METHODS: We studied 82 deceased donor renal transplantation. We assessed the following measures: dialysis-dependent delayed graft function (ddDGF), extended DGF, serum creatinine level at day 7, creatinine reduction ratio at day 7, urine output at day 1 and at day 7 posttransplantation (UO7). RESULTS: Only UO7 showed a significant result upon multivariate analysis (P < .0001). It was less influenced by dialysis with respect to measures based upon serum creatinine. By Receiver Operating characteristic (ROC) analysis, it showed an elevated area under the curve (0.811), with a cut-off value of 500 mL/24 h, showing high sensitivity (98.5%). CONCLUSIONS: UO7 may be of clinical utility to assess the risk for subsequent renal dysfunction.

Predictive characteristics of delayed graft function after expanded and standard criteria donor kidney transplantations.

Delayed graft function (DGF) represents one of the most common complications after kidney transplantation. The increased use of expanded criteria donors (ECD) is related to a greater risk for DGF. The objective of our study was to analyze the incidence of DGF among ECD versus standard criteria donors (SCD). Among 121 cases we obtained 2 groups: group A (SCD; n = 75) and group B (ECD; n = 46). Group B was composed of older donors (P < .0001), with an increased incidence of diabetes mellitus (DM; P < .0001), arterial hypertension (AH; P < .0001), cerebrovascular accidents (P = .013), and lower creatinine clearances (CrCl; P = .008). Recipient age was significantly lower among group A (P < .0001), with an increased incidence of donor hypotensive episodes (P = .016). The global incidence of DGF was 40 patients (33%), who were mainly in group B (P = .004). Analyzing the entire population, donor age >or= 60 years (P = .005), CrCl < 40 mL/min (P = .025), donor history of DM (P = .026) and AH (P = .017), and cold ischemia time > 15 hours (P < .0001) were parameters related to increased incidences of DGF. A biopsy score of 3 was not significantly associated with DGF. The results of our study underlined the increased risk for DGF related to the use of ECD. Donor age >or= 60 years and cold ischemia time > 15 hours showed strong associations with this complication.

Hemodynamic improvement as an additional parameter to evaluate the safety and tolerability of the molecular adsorbent recirculating system in liver failure patients.

BACKGROUND: The molecular adsorbent recirculating system (MARS) is an extracorporeal acute liver failure (ALF) support system method using albumin-enriched dialysate to remove albumin-bound toxins. PATIENTS AND METHODS: Since 1999 we performed 2027 MARS treatments in 191 patients: 39 fulminant hepatic failure (FHF), 16 primary nonfunction (PNF), 21 delayed function (DF), 94 acute-on-chronic liver failure (AoCHF), 7 post-hepatic resection, and 14 intractable pruritus. RESULTS: We divided the complications by the AoCHF versus the ALF populations. Among 83 ALF patients, we observed worsening of hemodynamic parameters in 16 patients: 3 with PNF, 2 with DF without retransplantation, 9 with FHF, and 2 after hepatic resection. Among 94 AoCHF patients, 42 showed hemodynamic instability requiring intensive care unit support. Our study did not note significant adverse effects (1.8%), except for infections and hemorrhage from the central venous catheter not due to MARS treatment. The thrombocytopenia was controlled through administration of platelets before the start of treatment when a patient showed a level under 30,000 mm(3). CONCLUSION: Our results confirmed that nonbiological hepatic support by MARS was safe and tolerable.
