Repeated resection for recurrent intrahepatic cholangiocarcinoma: A retrospective German multicentre study.

Background Tumour recurrence is common after resection of intrahepatic cholangiocarcinoma (ICC). Repeated resection is a potential curative treatment, but outcomes are not well-defined thus far. The aim of this retrospective multicentre cohort study was to show the feasibility and survival of repeated resection of ICC recurrence. Methods Data were collected from 18 German hepato-pancreatico-biliary centres for patients who underwent repeated exploration of recurrent ICC between January 2008 and December 2017. Primary end points were overall (OS) and recurrence-free survival from the day of primary and repeated resection. Results Of 156 patients who underwent repeated exploration for recurre…

Extended resection of intrahepatic cholangiocarcinoma: A retrospective single-center cohort study

Abstract Background For complete removal of intrahepatic cholangiocarcinoma (ICC), extended resection is often necessary. Information on the influence of visceral or vascular extension, extended resection, or postoperative morbidity on survival is scarce. The aim of this study was to show the impact of an aggressive surgical attitude on morbidity, mortality, and long-term outcome. Materials and methods All explorations at a high volume tertiary center between January 2008 and June 2018 with histological proof of ICC were included in this retrospective cohort study. The primary outcome was the extent of resection, secondary outcomes were postoperative morbidity, and their influence on overal…

Influence of Lymphangio (L), Vascular (V), and Perineural (Pn) Invasion on Recurrence and Survival of Resected Intrahepatic Cholangiocarcinoma

(1) Background: Intrahepatic cholangiocarcinoma (ICC) is a rare malignancy. Besides tumor, nodal, and metastatic status, the UICC TNM classification describes further parameters such as lymphangio- (L0/L1), vascular (V0/V1/V2), and perineural invasion (Pn0/Pn1). The aim of this study was to analyze the influence of these parameters on recurrence and survival. (2) Methods: All surgical explorations for patients with ICC between January 2008 and June 2018 were collected and further analyzed in our institutional database. Statistical analyses focused on perineural, lymphangio-, and vascular invasion examined histologically and their influence on tumor recurrence and survival. (3) Results: Of 2…

The addition of TACE to palliative chemotherapy is associated with extended survival in unresectable intrahepatic cholangiocarcinoma

The Addition of Transarterial Chemoembolization to Palliative Chemotherapy Extends Survival in Intrahepatic Cholangiocarcinoma

Incidence and mortality of intrahepatic cholangiocarcinoma (iCCA) have been increasing continuously. Recent studies suggest that the combination of palliative chemotherapy (pCTX) and transarterial chemoembolization (TACE) improves overall survival (OS). This study aimed to evaluate the outcome of patients treated with TACE and pCTX in unresectable iCCA at our tertiary care center. A group of 14 patients was treated with both pCTX and TACE. The non-randomized control group of 59 patients received pCTX alone. Patients received a median of two pCTX lines in both groups. Those treated with TACE underwent a median number of 3.5 sessions. Median OS from the time of unresectability was 26.2 months…

Transanal total mesorectal excision for restorative coloproctectomy in an obese high-risk patient with colitis-associated carcinoma

Transanal total mesorectal excision (TaTME) offers great potential for the treatment of malign and benign diseases. However, laparoscopic-assisted TaTME in ulcerative colitis has not been described in more than a handful of patients. We present a 47-year-old highly comorbid female patient with an ulcerative colitis-associated carcinoma of the ascending colon and steroid- refractory pancolitis. A two-stage restorative coloproctectomy including right-sided complete mesocolic excision was conducted. The second step consisted of a successful nerve-sparing TaTME and a handsewn ileal pouch-anal anastomosis. TaTME may extend the possible treatment options in inflammatory bowel disease, especially …

Limits of Surgical Resection for Bile Duct Cancer

<b><i>Introduction:</i></b> Perihilar cholangiocarcinoma is the most frequent cholangiocarcinoma and poses difficulties in preoperative evaluation. For its therapy, often major hepatic resections as well as resection and reconstruction of the hepatic artery or the portal vein are necessary. In the last decades, great advances were made in both the surgical procedures and the perioperative anesthetic management. In this article, we describe from our point of view which facts represent the limits for curative (R0) resection in perihilar cholangiocarcinoma. <b><i>Methods:</i></b> Retrospective data of a 6-year period (2008-2014) was collected in …

Survival Prediction in Intrahepatic Cholangiocarcinoma: A Proof of Concept Study Using Artificial Intelligence for Risk Assessment

Several scoring systems have been devised to objectively predict survival for patients with intrahepatic cholangiocellular carcinoma (ICC) and support treatment stratification, but they have failed external validation. The aim of the present study was to improve prognostication using an artificial intelligence-based approach. We retrospectively identified 417 patients with ICC who were referred to our tertiary care center between 1997 and 2018. Of these, 293 met the inclusion criteria. Established risk factors served as input nodes for an artificial neural network (ANN). We compared the performance of the trained model to the most widely used conventional scoring system, the Fudan score. Pr…

Quality-based assessment of camera navigation skills for laparoscopic fundoplication.

Summary Laparoscopic fundoplication is considered the gold standard surgical procedure for the treatment of symptomatic hiatus hernia. Studies on surgical performance in minimally invasive hiatus hernia repair have neglected the role of the camera assistant so far. The current study was designed to assess the applicability of the structured assessment of laparoscopic assistance skills (SALAS) score to laparoscopic fundoplication as an advanced and commonly performed laparoscopic upper GI procedure. Randomly selected laparoscopic fundoplications (n = 20) at a single institute were evaluated. Four trained reviewers independently assigned SALAS scoring based on synchronized video and voice rec…

Intrahepatic cholangiocarcinoma: Introducing the preoperative prediction score based on preoperative imaging.

Intrahepatic cholangiocarcinoma (ICC) still has a poor long-term outcome, even after complete resection. We investigated different parameters gathered in preoperative imaging and analyzed their influence on resectability, recurrence, and survival.All patients who underwent exploration due to ICC between January 2008 and June 2018 were analyzed retrospectively. Kaplan-Meier model, log-rank test and Cox regression were used.Out of 184 patients, 135 (73.4%) underwent curative intended resection. Median overall survival (OS) was 22.2 months with a consecutive 1-, 3- and 5-year OS of 73%, 29%, and 17%. Median recurrence-free survival (RFS) was 9.3 months with a consecutive 1-, 3- and 5-year RFS …

Unfused Liver Segments: a Case Report of an Unknown Phenotype of the Conradi-Hünermann-Happle Syndrome

Background: Since its description in 1957, Couinaud`s classification of the segmental organization of the liver has remained valid. However, recent investigations by 3-dimensional computed tomography suggest a significant variability of the vascular anatomy and segment volume. Here, we report a surprise finding during the laparoscopic cholecystectomy of a patient with Conradi-Hünermann-Happle syndrome, in whom the liver segments were not fused.
 Case report: Laparoscopic cholecystectomy was performed because of recurrent biliary pancreatitis in a 47 year-old male patient, who had been diagnosed with Conradi-Hünermann-Happle syndrome. Upon direct view, the liver parenchyma appeared norm…

The role of sarcopenia in patients with intrahepatic cholangiocarcinoma: Prognostic marker or hyped parameter?

BACKGROUND & AIMS Sarcopenia has emerged as a prognostic parameter in numerous cancer entities. Current research favours its role as a determining factor for overall survival (OS) in patients with intrahepatic cholangiocarcinoma (ICC); however, it is unclear whether sarcopenia is a truly independent survival predictor if combined with established prognostic factors. METHODS Between 1997-2018, 417 patients with histopathologically confirmed ICC were referred to our centre, of whom 293 were included in this study. Cross-sectional imaging, laboratory examinations and histopathological reports were retrospectively analysed. Psoas muscle index (PMI) as easy-to-measure marker of sarcopenia was ca…

Visceral infiltration of intrahepatic cholangiocarcinoma is most prognostic after curative resection - Retrospective cohort study of 102 consecutive liver resections from a single center

Intrahepatic cholangiocarcinoma (ICC) is a rare malignancy, and therefore large unicenter series on the surgical outcome are rare in the literature, and prognostic factors for overall survival in the literature vary widely.All patients who underwent surgery for ICC were prospectively recorded. The type of resection, operative details, histological results, morbidity, mortality, overall and recurrence-free survivals as well as prognostic factors were assessed. Prognostic factors were examined by univariate and multivariate analyses. P-values0.05 were considered significant.Between January 2008 and December 2015, 102 patients underwent a resection with curative intent and were included in thi…
