In patients with cirrhosis with severe thrombocytopenia (platelet count [PC] 100 × 109/L), intermediate (51‐100 × 109/L), and low (≤50 × 109/L). PC was also analyzed as a continuous covariate on multivariable analysis. The primary endpoint was major perioperative bleeding. The overall event rate of major perioperative bleeding was 8.9% and was not found to differ significantly between the high, intermediate, and low platelet groups (8.1% vs. 10.2% vs. 10.8%, P = 0.48). On multivariable analysis, greater age, aspartate aminotransferase, lower hemoglobin, and treatment with LR (vs. RFA) were found to be significant independent predictors of major perioperative bleeding, with associations with disease etiology and year of surgery also observed. After adjusting for these factors, the association between PC and major perioperative bleeding remained nonsignificant. Conclusion: Major perioperative bleeding was not significantly associated with PC in patients with cirrhosis undergoing surgical treatment of HCC, even when their PC was

Laparoscopic cholecystectomy (LC) is one of the most frequently performed gastrointestinal surgeries worldwide. Bile duct injury (BDI) represents the most serious complication of LC, with an incidence of 0.3%-0.7%, resulting in significant perioperative morbidity and mortality, impaired quality of life, and high rates of subsequent medico-legal litigation. In most cases, the primary cause of BDI is the misinterpretation of biliary anatomy, leading to unexpected biliary lesions. Near-infrared fluorescent cholangiography is widely spreading in clinical practice to delineate biliary anatomy during LC in elective and emergency settings. The primary aim of this article was to perform an up-to-date overview of the evolution of this method 12 years after the first clinical application in 2009 and to highlight all advantages and current limitations according to the available scientific evidence.

Background: Indocyanine green (ICG) fluorescence imaging has been extensively used in a variety of applications in visceral surgery. In minimally invasive liver resections, the detection of small s...

Natural killer (NK) cells play a pivotal role in cancer immune surveillance, and activating the receptor/ligand interaction may contribute to control the development and evolution of hepatocellular carcinoma (HCC). We investigated the role of the natural killer group 2 member D (NKG2D) activating receptor and its ligand, the major histocompatibility complex class I chain-related protein A and B (MICA/B) in patients with cirrhosis and HCC subjected to surgical resection, patients with cirrhosis and no HCC, and healthy donors (HD). The NKG2D-mediated function was determined in peripheral blood (PB), in tumor-infiltrating lymphocytes (NK-TIL), and in matched surrounding liver tissue (NK-LIL). A group of patients treated with sorafenib because of clinically advanced HCC was also studied. A humanized anti-MICA/B monoclonal antibody (mAb) was used in in vitro experiments to examine NK cell-mediated antibody-dependent cellular cytotoxicity. Serum concentrations of soluble MICA/B were evaluated by ELISA. IL-15 stimulation increased NKG2D-dependent activity which, however, remained dysfunctional in PB NK cells from HCC patients, in line with the reduced NKG2D expression on NK cells. NK-TIL showed a lower degranulation ability than NK-LIL, which was restored by IL-15 stimulation. Moreover, in vitro IL-15 stimulation enhanced degranulation and interferon-&gamma, production by PB NK from patients at month one of treatment with sorafenib. Anti-MICA/B mAb associated with IL-15 was able to induce PB NK cytotoxicity for primary HCC cells in HD and patients with HCC, who also showed NK-TIL degranulation for autologous primary HCC cells. Our findings highlight the key role of the NKG2D-MICA/B axis in the regulation of NK cell responses in HCC and provide evidence in support of a potentially important role of anti-MICA/B mAb and IL-15 stimulation in HCC immunotherapy.

The optimal treatment for hepatocellular carcinoma (HCC) is surgical resection. However, only a small percentage of patients are amenable to this option. Percutaneous radiofrequency interstitial thermal ablation (TA) proved to be effective in the treatment of unresectable HCC. Recent advances in laparoscopic ultrasound have improved the accuracy in detecting small intrahepatic HCC nodules missed by pre-operative imaging techniques. Our objective was to evaluate an operative combination of laparoscopic ultrasound with laparoscopic thermoablation (LTA) in the treatment of HCC not amenable to liver resection. The aim of our review was to evaluate the advantages and limits of the laparoscopic approach according the criteria of the evidence-based medicine. LTA of HCC proved to be a safe and effective technique both in the short- and long-term follow-up period. This technique may be indicated in selected cases when the percutaneous approach to the lesion is very difficult or contraindicated.

Background: Primary laparoscopic approach for the treatment of cancers of the biliary tract is not popular in the surgical community. The aim of this study is to report the short-term data of patients who underwent total laparoscopic radical cholecystectomy for gallbladder cancer (GBC) at a single center of specialized hepatobiliary surgery. Methods: From November 2016 to January 2019, we routinely performed a laparoscopic approach for two groups of patients: (1) patients with primary GBC (diagnosed preoperatively) and (2) patients with incidental GBC (IGBC) discovered after cholecystectomy. Results: Our retrospective study included 18 patients (7 primary GBCs, 11 IGBCs). Conversion rate from laparoscopy to laparotomy was 28.6% and 9.1%, respectively, for the two groups, but this difference was not statistically significant (P = .28). Only 3 patients had liver recurrence (27.3%) and 1 had liver invasion (14.3%). A more advanced T category and TNM stage were presented in the preoperative suspicion cases (T3-T4 18.2% versus 57.1%, P = .06, stage IVA-B 9.1% versus 71.4%, P = .017). Regional lymphadenectomy was performed in 15 patients, in 73.3% the total number of lymph nodes (total LNs) retrieved was more than 7 (7-12 LNs in 66.7% of patients and >12 LNs in 6.6% of patients). The mean postoperative long stay was 8 days excluding for cases who developed complication. Conclusions: Laparoscopy can be considered a safe treatment for IGBC or primary GBC. The T3 stage with only liver involvement was not a contraindication. The real reasons that lead to convert the laparoscopic procedure were due to oncological concerns, unrelated to the liver infiltration.

Introduction The wide use of hemoclips during laparoscopic surgery has led to a variety of unusual complications, among these, there is the migration of Hem-o-Lok clip into the duodenum. We performed a literature review of all cases of Hem-o-Lok clip migration into the duodenum after laparoscopic digestive surgery reported in literature. Evidence acquisition All relevant articles were extracted up to June 2019 based on the results of searches in MEDLINE, PubMed, Scopus, Web of Science and Google Scholar. Evidence synthesis At the time of this review, a total of seven cases have been described. The mean age was 49 years and the majority of these patients were women (57%). Previous laparoscopic surgery was performed for cholecystectomy (four patients), cholecystectomy with common bile duct exploration (one patient), right hemicolectomy (one patient) and distal gastrectomy (one patient). Symptoms occurred from 3 months to 2 years after laparoscopic surgery. The majority of patients developed symptoms of bowel occlusion and abdominal pain. Three patients remained asymptomatic. In many cases the Hem-o-Lok wedged into the wall of the first or second portion of the duodenum. In all cases, esophageal gastroduodenoscopy was the primary modality to make the diagnosis. Initial treatment was conservative with watch-and-wait strategy or proton pump inhibitors followed by endoscopic removal, while surgical treatment was required in two cases. Conclusions The application of Hem-o-Lok clip during laparoscopic surgery is safe and effective. Postoperative Hem-o-Lok migration into the duodenum is rare. The treatment could be conservative in the majority of cases.

The surgical therapy of choice for hepatocellular carcinoma (HCC) is liver transplantation (LT) or hepatic resection, although only a small percentage of patients can undergo these procedures. Microwave thermal ablation (MWTA) can be an effective alternative treatment for HCC that complicates a cirrhotic liver disease, either as a final procedure or for downstaging patients on the waiting list for LT, or in combination with resective surgery to achieve oncological radicality.The purpose of this retrospective study was to evaluate experience with the laparoscopic approach of MWTA at our center.In a cohort of 35 consecutive patients undergoing MWTA with laparoscopic approach between January, 2013 and May, 2016, we reviewed the demographic data, the Barcelona clinic liver cancer stage, the severity of cirrhotic liver disease, the size of the ablated lesion, the duration of the procedure, and complications occurring within 90 days of surgery.MWTA was performed by applying one to three hepatic parenchymal insertions (mean 1.8) per patient. The mean duration of surgery was 163 ± 18 minutes. There was no blood loss in any of the procedures. Complete necrosis on CT scan was achieved in 26/35 patients (75%). The mean hospital stay was 4.6 (range 2-7) days; major complications were postablation syndrome in 2/35 (5.7%), peritoneal fluid in 4/35 (11.4%), and transient jaundice in 1/35 (2.8%) patients. There was no mortality.Laparoscopic MTWA is a safe and effective treatment for unresectable HCC and when a percutaneous procedure is not feasible.

The use of endoscopic techniques to cure small sized, well differentiated early gastric cancer has been adopted worldwide. In the Eastern world, endoscopic resection is being increasingly utilized to treat small undifferentiated early gastric cancer according to the extended criteria proposed by the Japanese Gastric Cancer Associations. However, studies in the Western world reported in these tumors a rate of nodal metastasis ranging between 5% and 20%, that is higher of those observed in Eastern counterparts. A tool to predict the risk of nodal dissemination would be of great use to guide treatment toward endoscopic resection. In our study, we propose E-cadherin expression as a biological factor to predict lymph node involvement. We retrospectively reviewed the E-cadherin (E-cad) expression profile of all histological specimens of undifferentiated early gastric cancer from two Oncologic Departments and compared it with several tumor characteristics. A total of 39 patients with early gastric cancer met the inclusion criteria, of which 16 (41%) pT1a, and 23 (58.9%) pT1b SM1. Thirty-two patients (82%) underwent subtotal gastrectomy, whereas total gastrectomy was performed in only seven cases (17.9%). Patients were divided into two groups: low E-cad expression (E-cad 0/1+, 10 patients) and high E-cad expression (E-cad 2+/3+, 29 patients) according to the immunohistochemical assay (ICH). On univariate analysis, we found an association between low E-cad expression and low grading tumor (p = 0.019), pure undifferentiated histotype (PU-type) (p = 0.014), and lymph node involvement (N+) (p < 0.001). The association between low E-cad expression and lymph node metastasis was confirmed by multivariate analysis (OR = 14.5, 95% CI 3.46-60.76, p < 0.001). The loss of expression of E-cad may be a simple biological factor to predict lymph nodes metastasis in patients with undifferentiated early gastric cancer. Additional larger prospective studies are necessary to confirm these findings.

Aim. To evaluate the technical feasibility and oncologic safety of laparoscopic radical cholecystectomy (LRC) for primary or incidental early gallbladder cancer (GBC) treatment. Methods. Articles reporting LRC for GBC were reviewed from the first case reported in 2010 to 2015 (129 patients). 116 patients had a preoperative diagnosis of gallbladder cancer (primary GBC). 13 patients were incidental cases (IGBC) discovered during or after a laparoscopic cholecystectomy. Results. The majority of patients who underwent LRC were pT2 (62.7% GBC and 63.6% IGBC). Parenchyma-sparing operation with wedge resection of the gallbladder bed or resection of segments IVb-V were performed principally. Laparoscopic lymphadenectomy was carried out according to the reported depth of neoplasm invasion. Lymph node retrieved ranged from 3 to 21. Some authors performed routine sampling biopsy of the inter-aorto-caval lymph nodes (16b1 station) before the radical treatment. No postoperative mortality was documented. Discharge mean day was POD 5th. 16 patients had post operative morbidities. Bile leakage was the most frequent post-operative complication. 5 y-survival rate ranged from 68.75 to 90.7 months. Conclusion. Laparoscopy can not be considered as a dogmatic contraindication to GBC but a primary approach for early case (pT1b and pT2) treatment.

This study reviewed all single experience of splenic injuries after colonoscopy in the last 40 years to define the possible risk factors and the management of this complication. A MEDLINE and a PubMed search was undertaken to identify articles in English, French, Spanish, and Italian from 1974 to 2012 using the key words: "splenic injury," "splenic rupture," and "colonoscopy." Data were analyzed using descriptive statistic. A total of 103 cases have been described in 75 reports. The majority of the patients were women (71.56%) and 6.85% underwent previous pelvic surgery. The mean age was 63 years (range, 29 to 90 y). About 61 of the 103 studies (59.2%) reported the presence or the absence of previous abdominal surgery and within these, only 31 of 61 patients (50.82%) underwent previous abdominal surgery. In this review, over half of the patients with splenic injury underwent colonoscopy for routine surveillance (62.75%), and only one third of the splenic injures were associated with biopsy or polypectomy. The majority of patients (78.57%) developed symptoms within the first 24 hours after colonoscopy and in a minority of cases (21.43%), there was a delayed presentation 24 hours after colonoscopy. Computed tomography was used as the primary modality to make the diagnosis in 69 of 98 cases (70.41%) and as a confirmatory test in many additional cases. Twenty-six of 102 patients (25.49%) were treated by conservative methods, whereas the majority of patients (69.61%) underwent splenectomy as a definitive treatment. Because of possible medicolegal implications, the endoscopists should consider mentioning splenic injury on the consent form of colonoscopy after bowel perforation and bleeding, particularly in higher risk patients.

Strangulated hernia remains one of the most common emergencies encountered in general surgery. During induction of general or spinal anesthesia, the potential self-reduction of a gan- grenous bowel can occur in approximately 1% of cases. In these cases, bowel viability can no longer be directly assessed unless a more extensive operation (laparoscopy or laparotomy) is per- formed. A simple alternative to unnecessary laparotomy or to a standard laparoscopy is a hernia sac laparoscopy (hernioscopy). Here, we presented 4 patients with a diagnosis of small-bowel obstruction secondary to incarcerated inguinal hernias, in which the incarcerated hernia content was evaluated by hernioscopy. Only 1 case presented persistent signs of bowel ischemia after hernia reduction and required a small-bowel segmental resection. All hernias were repaired using prosthetic tension-free technique. Hernia sac laparoscopy (hernioscopy), the introduction of the laparoscope through an open inguinal hernia sac, can be useful to evaluate the viability of the incarcerated hernia content, to avoid unnecessary laparotomy.

Highlights • Appendiceal diverticulitis is often overlooked with high risk of perforation. • Appendiceal diverticula is often associated to appendiceal neoplasm. • Accurate appendectomy should be performed in order to permit appropriate pathological examination. • Prophylactic appendectomy should be performed in asymptomatic patients with appendiceal., Introduction Appendiceal diverticulitis is a rare pathology that mimics acute appendicitis. Appendiceal diverticula are classified into congenital and acquired with difference in incidence and pathogenesis. Appendiceal diverticulitis is often overlooked because of mildness of symptomatology with increasing risk of complications, such as perforation. Appendiceal diverticula are often associated to higher risk of neoplasm especially carcinoid tumors and mucinous adenomas. Presentation of case A 40-year-old caucasic male presented into Emergency Room with right lower quadrant pain associated with vomit, abdominal tenderness, fever and moderate leukocytosis (11.93 × 10; neutrophils 78.5%). Acute appendicitis was suspected and a surgical approach was chosen with a McBurney access. The removed specimen (Figs. 1 and 2) was 11 cm long with multiple hyperaemic and oedematous diverticular protrusions. The postoperative course was regular. Discharging was on 4th postoperative day in optimal clinical conditions. The histological examination (Fig. 3) showed acute inflammation of appendiceal pseudodiverticula with acute peridiverticulitis and abscess. Discussion Currently, appendiceal diverticulitis is often overlooked with high risk of complications, above all perforation. Attention should be kept during the surgical procedure and the patholological examination in order to identify any associated neoplasm. Conclusion Appendiceal diverticulitis should be considered in adult male patients with right lower quadrant pain or tenderness. Accurate appendectomy should be performed in order to permit an appropriate pathological examination and possible associate neoplasm should always be searched through. Prophylactic appendectomy should be performed in case of incidental finding of appendiceal diverticula in asymptomatic patients in order to avoid the high perforation risk.

To verify the utility of fluorescent cholangiography for more rigorous identification of the extrahepatic biliary system.MEDLINE and PubMed searches were performed using the key words "fluorescent cholangiography", "fluorescent angiography", "intraoperative fluorescent imaging", and "laparoscopic cholecystectomy" in order to identify relevant articles published in English, French, German, and Italian during the years of 2009 to 2014. Reference lists from the articles were reviewed to identify additional pertinent articles. For studies published in languages other than those mentioned above, all available information was collected from their English abstracts. Retrieved manuscripts (case reports, reviews, and abstracts) concerning the application of fluorescent cholangiography were reviewed by the authors, and the data were extracted using a standardized collection tool. Data were subsequently analyzed with descriptive statistics. In contrast to classic meta-analyses, statistical analysis was performed where the outcome was calculated as the percentages of an event (without comparison) in pseudo-cohorts of observed patients.A total of 16 studies were found that involved fluorescent cholangiography during standard laparoscopic cholecystectomies (n = 11), single-incision robotic cholecystectomies (n = 3), multiport robotic cholecystectomy (n = 1), and single-incision laparoscopic cholecystectomy (n = 1). Overall, these preliminary studies indicated that this novel technique was highly sensitive for the detection of important biliary anatomy and could facilitate the prevention of bile duct injuries. The structures effectively identified before dissection of Calot's triangle included the cystic duct (CD), the common hepatic duct (CHD), the common bile duct (CBD), and the CD-CHD junction. A review of the literature revealed that the frequencies of detection of the extrahepatic biliary system ranged from 71.4% to 100% for the CD, 33.3% to 100% for the CHD, 50% to 100% for the CBD, and 25% to 100% for the CD-CHD junction. However, the frequency of visualization of the CD and the CBD were reduced in patients with a body mass index35 kg/m(2) relative to those with a body mass index35 kg/m(2) (91.0% and 64.0% vs 92.3% and 71.8%, respectively).Fluorescent cholangiography is a safe procedure enabling real-time visualization of bile duct anatomy and may become standard practice to prevent bile duct injury during laparoscopic cholecystectomy.

Gastric cancer is one of the most dreadful neoplastic diseases and remains the second cause of cancer death worldwide. Patients who develop peritoneal metastasis have a poor prognosis, with a median survival of less than 6 months. Despite being the cause of 60% of deaths from gastric cancer, peritoneal metastasis can still be considered a local disease and a local multidisciplinary approach can improve the prognosis even in this end-stage disease. At present, hyperthermic intraperitoneal chemotherapy (HIPEC) is the most widely accepted treatment for peritoneal surface diseases and can be performed in patients with different stages of cancer and with various antitumoral drugs. We performed a systematic review of the current status of HIPEC in the treatment of gastric peritoneal metastasis in an attempt to obtain answers to the questions that still remain: do results differ with these different methods? Does HIPEC exert a significant effect on the intracavitary delivery of drugs? Which patients should be treated and which should not? What can we expect from this approach in terms of survival, morbidity, and mortality? On reviewing the literature, despite the lack of trials comparing the different methods, we found that HIPEC has been shown to be an effective tool whenever a complete or an almost complete resection of the peritoneal implants can be performed. Therefore, it is advisable to refer all at-risk patients to specialized centers to be enrolled in randomized trials to achieve truly reliable results.

Background Gastrointestinal stromal tumors (GISTs) represent 85% of all mesenchymal neoplasms that affect the gastrointestinal (GI) tract. These GISTs range in size from small lesions to large masses. Often they are clinically silent until they reach a significant size, so their discovery is usually incidental. Case presentation A 67-year-old man was admitted at our general surgery department with a persistent abdominal pain in the left hypochondrium, associated with nausea and vomiting. Clinical examination revealed a palpable mass in the epigastrium and in the left hypochondrium, which was approximately 40 cm long. Ultrasonography and computed tomography of the abdomen showed a large mass of 40 × 25 cm, which extended from the posterior wall of the stomach to the spleen, involving the body and the tail of the pancreas. The patient underwent en-block resection of the mass, sleeve resection of the stomach, and distal pancreatectomy-splenectomy. The histopathology of the resected specimen was consistent with a gastrointestinal stromal tumor of the stomach (positive for CD 117) with a high risk of malignancy (mitotic count >5/50 high-power fieldand Ki67/Mib1 >10%). The postoperative course was uneventful and treatment with imatinib mesylate began immediately. The patient appears to be disease free after four years. Conclusions Giant GISTs of the stomach are rare. Surgical resection with curative intent is feasible. The combination of surgical resection and imatinib can provide long-termdisease-free survival. An R0 resection is the best achievable treatment, therefore the patient should be evaluated over time for potential resectability.

Multiple factors have been described among the causes of non-hereditary colorectal cancer. In Western countries, the most common risk factors include upper-middle socioeconomic status and dietary regimens rich in proteins and animal fats. High consumption of red meats, smoked foods, cold cuts, or canned foods is believed to contribute to carcinogenesis as they directly affect epithlial turnover and cause metabolism of biliary acids. Dietary fibers have protective effects in that they capture the fats and biliary acids, thereby inhibiting their activity. Tobacco smoking acts both locally and systemically on the colorectal mucosa through the production of carcinogenic agents. Finally, the action of alcohol, in association with nicotine addiction, also increases the risk of developing colorectal tumors. Knowledge of dietary and environmental factors is of paramount importance in implementing preventive strategies for colorectal cancer.

Splenic rupture is a rare complication of colonoscopy. For this reason the diagnosis could be delayed and the outcome dismal. Fifty-four cases of splenic rupture after colonoscopy have been described in the literature. The majority of the cases required emergent or delayed splenectomy, 13 of these cases were treated conservatively. The main feature that stands out from the review of the literature is the "surprise" of this unexpected complication. This factor explains the elevated mortality (2 out of 54 cases), likely due to the delay in diagnosis. The case here described is probably among the most complex published in the literature; in fact the presence of dense intra-abdominal adhesions not only contributed to the complication itself, but also explain the confinement of the hemoperitoneum to the left supra-mesocolic space and the delayed presentation (13 days from the time of the trauma).

To evaluate the impact of incidental gallbladder cancer on surgical experience.Between 1998 and 2008 all cases of cholecystectomy at two divisions of general surgery, one university based and one at a public hospital, were retrospectively reviewed. Gallbladder pathology was diagnosed by history, physical examination, and laboratory and imaging studies [ultrasonography and computed tomography (CT)]. Patients with gallbladder cancer (GBC) were further analyzed for demographic data, and type of operation, surgical morbidity and mortality, histopathological classification, and survival. Incidental GBC was compared with suspected or preoperatively diagnosed GBC. The primary endpoint was disease-free survival (DFS). The secondary endpoint was the difference in DFS between patients previously treated with laparoscopic cholecystectomy and those who had oncological resection as first intervention.Nineteen patients (11 women and eight men) were found to have GBC. The male to female ratio was 1:1.4 and the mean age was 68 years (range: 45-82 years). Preoperative diagnosis was made in 10 cases, and eight were diagnosed postoperatively. One was suspected intraoperatively and confirmed by frozen sections. The ratio between incidental and nonincidental cases was 9/19. The tumor node metastasis stage was: pTis (1), pT1a (2), pT1b (4), pT2 (6), pT3 (4), pT4 (2); five cases with stage Ia (T1 a-b); two with stage Ib (T2 N0); one with stage IIa (T3 N0); six with stage IIb (T1-T3 N1); two with stage III (T4 Nx Nx); and one with stage IV (Tx Nx Mx). Eighty-eight percent of the incidental cases were discovered at an early stage (≤ II). Preoperative diagnosis of the 19 patients with GBC was: GBC with liver invasion diagnosed by preoperative CT (nine cases), gallbladder abscess perforated into hepatic parenchyma and involving the transversal mesocolon and hepatic hilum (one case), porcelain gallbladder (one case), gallbladder adenoma (one case), and chronic cholelithiasis (eight cases). Every case, except one, with a T1b or more advanced invasion underwent IVb + V wedge liver resection and pericholedochic/hepatoduodenal lymphadenectomy. One patient with stage T1b GBC refused further surgery. Cases with Tis and T1a involvement were treated with cholecystectomy alone. One incidental case was diagnosed by intraoperative frozen section and treated with cholecystectomy alone. Six of the nine patients with incidental diagnosis reached 5-year DFS. One patient reached 38 mo survival despite a port-site recurrence 2 years after original surgery. Cases with non incidental diagnosis were more locally advanced and only two patients experienced 5-year DFS.Laparoscopic cholecystectomy does not affect survival if implemented properly. Reoperation should have two objectives: R0 resection and clearance of the lymph nodes.

Introduction : Gallbladder cancer (GBC) is the fifth most common neoplasm of the gastrointestinal tract and the most common cancer of the biliary tract. GBC is suspected preoperatively in only 30–40% of patients. The other 60–70% are discovered incidentally (IGBC) by the pathologist on a gallbladder specimen following cholecystectomy for benign diseases such as polyps, gallstones, and cholecystitis. Materials and methods : Between 1995 and 2011, 30 cases of GBC, who underwent resection with curative intent in our institutions, were retrospectively reviewed. They were analyzed for demographic data, and type of operation, surgical morbidity and mortality, histopathological classification, and survival. Incidental GBC was compared with suspected or preoperatively diagnosed GBC. Overall survival, disease-free survival (DFS) and the difference in DFS between patients previously treated with laparoscopic cholecystectomy and those who had oncological resection as first intervention were analyzed. The authors also present a systematic review to evaluate the role of extended surgery in the treatment of the incidental GBC. Results : GBC was diagnosed in 30 patients, 16 women and 14 men. The M/F ratio was 1:1.14 and the mean age was 69.4 years (range 45–83 years). A preoperative diagnosis was possible only in 14 cases; fourteen of the incidental cases were diagnosed postoperatively after the pathological examination; two were suspected intraoperatively at the opening of the surgical specimen and then confirmed by frozen sections. The ratio between incidental and nonincidental cases was 1, 14/1, with twelve cases discovered after laparoscopic cholecystectomy. Eighty-one per cent of the incidental cases were discovered at an early stage (≤II). The preoperative diagnosis of the 30 patients with GBC was: GBC with liver invasion diagnosed by preoperative CT (nine cases); gallbladder abscess perforated into hepatic parenchyma and involving the transversal mesocolon and hepatic hilum (one case); porcelain gallbladder (three cases); gallbladder adenoma (four cases); and chronic cholecystolithiasis (thirteen cases). Every case, except one, with a T1b or more advanced invasion underwent IVb + V wedge liver resection and pericholedochic/hepatoduodenal lymphoadenectomy. One patient refused further surgery. Cases with Tis and T1a involvement were treated with cholecystectomy alone. Nine of the sixteen patients with incidental diagnosis reached 5-year DFS (56.25%) and eight of them are recurrence free. Surprisingly, one patient reached 38 mo survival despite a port-site recurrence (the only one in our experience) 2 years after the original surgery requiring further resection. Cases with non incidental diagnosis were more locally advanced and only two patients experienced 5 years DFS (Tables 2 and 3). Conclusion : Laparoscopic cholecystectomy does not affect survival if implemented properly. Reoperation should have two objectives: R0 resection and clearance of the lymph nodes.

Since Kocher and Billroth refined an acceptable technique, the thyroidectomy has become one of the most frequent procedures in endocrine surgery and bilateral total thyroidectomy is performed in the majority of thyroid diseases. This work evaluated the use of the Harmonic ® FOCUS and traditional suture ligation (knot and tie) technique in a prospective, randomized study of open thyroidectomy. Eighty two patients were randomized and divided into two similarly sized groups: the Harmonic ® FOCUS group (F group) and traditional group (T group). The use of the harmonic FOCUS shows some statistically significant advantages limited to a few intraoperative parameters: surgical time and volume of blood loss. The surgical time was significantly shorter in F group than in the T group (105 ± 27 min vs 143 ± 32 respectively; p Intraoperative volume blood loss was significantly more in the T group than in the F group (36 ± 23 ml vs. 24 ± 18; p The postoperative parameters (volume of drainage fluid, serum calcium at 12 and 48 h, hypocalcemia, wound complication, RLN palsy, postoperative pain and length of hospital stay) showed no statistical difference. The Harmonic Focus may provide a cost-effective option only in high volume centers where reducing operative time may balance the number of daily procedures.

Highlights • Biologically, cutaneous and ocular melanoma may be considered different, in terms of both metastatic diffusion and metastatic latency. • The principal target organ for metastasis of the ocular melanoma is the liver. • This distinctive behaviour is also sustained by a different metastatic latency to the liver. • In ocular melanoma synchronous disease accounts for less than 1% of the cases, the majority of patients will develop liver metastasis during the subsequent follow-up period and some of these will present with metastatic ocular melanoma to the liver several years after the treatment of the primary tumor., Introduction Choroidal melanoma is the most common primary intraocular malignant tumour and the second most common type of primary malignant melanoma in the body. Biologically, cutaneuous and ocular melanoma may be considered different, in terms of both metastatic diffusion and metastatic latency. The principal target organ for metastasis of the ocular melanoma is the liver.This distinctive behaviour is also sustained by different metastatic latency, as some patients present with metastatic ocular melanoma several years after the treatment of the primary tumor. Presentation of case A 60 year-old male who had undergone left ocular enucleation for choroid melanoma 20 years ago was referred to our department with a three months history of diffuse abdominal pain, fever, weight loss and massive ascites. Abdominal ultrasonography (US) and total body computed tomography (CT) scan were performed and revealed diffuse liver metastases, associated with peritoneal carcinosis, bilateral adrenal metastases and a large mass in the left kidney compatible with another secondary localization. An ultrasound guided fine needle agobiopsy (FNA) of liver lesions was performed and the pathological findings led to the diagnosis of liver metastasis from choroidal melanoma. The patient died a few weeks later for hepatic failure. Discussion Currently, there is no consensus regarding the optimal follow-up in terms of screening modality or time interval after the treatment of the primary ocular melanoma. Conclusion Patients with gastrointestinal symptoms and a history of choroidal melanoma should be investigated for the presence of gastrointestinal or liver metastases, although the original primary malignancy was diagnosed years before the patient’s presentation.

Gastric neuroendocrine tumors (g-NETs), which originate from gastric enterochromaffin-like (ECL) mucosal cells and account for 2.4% of all carcinoids, are increasingly recognized due to expanding indications of upper gastrointestinal endoscopy. Often silent and benign, g-NETs may however, be aggressive and sometimes they mimic the course of gastric adenocarcinoma. Current nosography distinguishes those occurring in chronic conditions with hypergastrinemia, as the type 1 associated with chronic atrophic gastritis, and the type 2 associated with Zollinger–Ellison syndrome in MEN1. Conversely, type 3 and 4 (according to some authors) are unrelated to hypergastrinemia and are frequently malignant, with a propension to develop distant metastases. While there is a general agreement concerning the treatment of malignant gastric neuroendocrine tumors, for types 1 and 2, current possibilities include surveillance, endoscopic polypectomy, surgical excision, associated or not with surgical antrectomy, or total gastrectomy. This report, based on our clinical experience, discusses how the size, number, depth, histological grading, staging with CT, MRI, and the use of recently developed somatostatin receptor tracers (68Ga-DOTATATE, 68Ga-DOTA-TOC) could allow the correct identification of a benign or malignant propensity of an individual tumor, thus avoiding underestimation or overtreatment of these uncommon neoplasms.

Gastric cancer is the second cause of death from cancer worldwide and the only chance to reach better outcomes lays on an early diagnosis. The need for non-invasive, low-cost tests is invoked also in countries in which imaging and endoscopic screening have already showed the ability to improve early diagnosis and overall survival. Genomic medicine could allow a better understanding of regulatory pathways driving the development and growth of gastric cancer and the characterization of specific molecular targets actually stimulate new drug developments. The knowledge of the role of Helicobacter pylori (HP) in gastric tumor pathogenesis has put new insides in the understanding of this peculiar disease and enriched the field of gastric biomarkers.

Numerous studies indagated the relationship between dietary pattern or specific nutrients and breast cancer (BC) risk and survival. Different ethnic o social groups show differences in breast cancer incidence that could be explained by different dietary patterns. Furthermore, many nutrients could reasonably increase the risk of cancer because of their content of carcinogens or their precursors as well as of promoting substances. However, the only convincing evidences linking life style to increased BC risk are related to obesity and moderate intake of alcohol and limited to postmenopause. Saturated fat, red meat, high temperature cooking have been indicated as possible risk factors, but adjusted analyses have not confirmed this association or have limited the relationship to specific subgroups. Even the protective effect of fiber, fruit, vegetables and phytoestrogens has been suggested but not definitively demonstrated. Thus, healthy dietary patterns, with abstention from alcohol and weight control, reduce the risk of cancer or at least improve the survival of affected women by reducing the incidence of comorbidities.

Background Breast cancer (BC) remains principally a disease of old ages; with 35-50% of cases occurring in women older than 65 years. Even mortality for cancer increases with aging: 19.7% between 65 and 74 years; 22.6% between 75 and 84 years; and 15.1% in 85 years or more. The study was aimed to investigate specific predictive factors for elderly patients so to select the best way to treat and follow these patients. Methods A search was performed on Medline, Embase, Scopus using the following Key words: Breast cancer, Breast neoplasms, Aged, Elder, Elderly, Eldest, Older, Survival analysis, Prognosis, Prognostic factors, Tumor markers, Biomarkers, Comorbidity, Geriatric assessment, Axilla, Axillary surgery. 3029 studies have been retrieved. Paper in which overall or disease free survival were not end points, or age class was not well defined, or the sample was too small, were excluded. At last 42 papers fulfilled the criteria. Results and discussion Lack of screening and delay in diagnosis may be responsible for the minor improvement in survival observed in elderly respect to younger breast cancer patients. Predictive factors are the same and must be assessed with the same attention reserved to younger women. Conclusions Most of elderly patient are fit to undergo standard treatment and can get the same benefits of younger women. Nevertheless it is possible that some older women with early breast cancer can be spared too aggressive treatments. Geriatric assessment and co-morbidities can affect the prognosis modifying surveillance, life expectancy and compliance to therapies. They can thus be useful to select the better treatment, either surgical or radio or hormone - or chemo-therapy.
