Outcome of a 3-day vs 7-day selective digestive tract decontamination-based regimen for oral antibiotic bowel decontamination in left-sided colorectal surgery: A noninferiority study.

Background: Colorectal surgery still experiences high rates of infectious complications, such as anastomotic leakage (AL) and surgical site infections (SSIs). Therefore, oral antibiotic bowel decontamination (OABD) has experienced a renaissance. However, data on perioperative selective digestive tract decontamination (SDD)-based regimens or combined bowel preparation are inconsistent.

Treatment of Colorectal Cancer in Certified Centers: Results of a Large German Registry Study Focusing on Long-Term Survival.

(1) Background: The WiZen study is the largest study so far to analyze the effect of the certification of designated cancer centers on survival in Germany. This certification program is provided by the German Cancer Society (GCS) and represents one of the largest oncologic certification programs worldwide. Currently, about 50% of colorectal cancer patients in Germany are treated in certified centers.

Is treatment in certified cancer centers related to better survival in patients with pancreatic cancer? Evidence from a large German cohort study.

Background: Treatment of cancer patients in certified cancer centers, that meet specific quality standards in term of structures and procedures of medical care, is a national treatment goal in Germany. However, convincing evidence that treatment in certified cancer centers is associated with better outcomes in patients with pancreatic cancer is still missing.

Methods: We used patient-specific information (demographic characteristics, diagnoses, treatments) from German statutory health insurance data covering the period 2009-2017 and hospital characteristics from the German Standardized Quality Reports.

Oral antibiotic bowel decontamination in open and laparoscopic sigmoid resections for diverticular disease.

Purpose: There is an ongoing debate on whether or not to use oral antibiotic bowel decontamination in colorectal surgery, despite the numerous different regimens in terms of antibiotic substances and duration of application. As we routinely use oral antibiotic bowel decontamination (selective decontamination of the digestive tract (SDD) regimen and SDD regimen plus vancomycin since 2016) in surgery for diverticular disease, our aim was to retrospectively analyze the perioperative outcome in two independent centers.

Methods: Data from two centers with a routine use of oral antibiotic bowel decontamination for up to 20 years of experience were analyzed for the perioperative outcome of 384 patients undergoing surgery for diverticular disease.

Adjuvant therapy is associated with improved overall survival in patients with pancreatobiliary or mixed subtype ampullary cancer after pancreatoduodenectomy - A multicenter cohort study.

Background/objective: The benefit of adjuvant therapy in ampullary cancer (AMPAC) patients following pancreatoduodenectomy (PD) is debated. The aim of this study was to determine the role of adjuvant therapy after pancreatoduodenectomy (PD) in histological subtypes of AMPAC.

Methods: Patients undergoing PD for AMPAC at 5 high-volume European surgical centers from 1996 to 2017 were identified.

Prognostic relevance of preoperative bilirubin-adjusted serum carbohydrate antigen 19-9 in a multicenter subset analysis of 179 patients with distal cholangiocarcinoma.

Background: Distal cholangiocarcinoma (DCC) is a rare malignancy and validated prognostic markers remain scarce. We aimed to evaluate the role of serum CA19-9 as a potential biomarker in DCC.

Methods: Patients operated for DCC at 6 high-volume surgical centers from 1994 to 2015 were identified from prospectively maintained databases.

High compliance with guideline recommendations but low completion rates of adjuvant chemotherapy in resected pancreatic cancer: A cohort study.

Background: Adjuvant chemotherapy (adCx) is an integral part of multimodal treatment in resected pancreatic ductal adenocarcinoma (PDAC) and is recommended by the German S3 guideline since 2007 in all patients. We aimed to investigate the impact of this guideline at our institution.

Methods: In 151 of 403 pancreatic resections performed histopathology revealed PDAC.

CONKO-005: Adjuvant Chemotherapy With Gemcitabine Plus Erlotinib Versus Gemcitabine Alone in Patients After R0 Resection of Pancreatic Cancer: A Multicenter Randomized Phase III Trial.

Purpose Gemcitabine is standard of care in the adjuvant treatment of resectable pancreatic ductal adenocarcinoma (PDAC). The epidermal growth factor receptor tyrosine kinase inhibitor erlotinib in combination with gemcitabine has shown efficacy in the treatment of advanced PDAC and was considered to improve survival in patients with primarily resectable PDAC after R0 resection. Patients and Methods In an open-label, multicenter trial, patients were randomly assigned to one of two study arms: gemcitabine 1,000 mg/m days 1, 8, 15, every 4 weeks plus erlotinib 100 mg once per day (GemErlo) or gemcitabine (Gem) alone for six cycles.

Minimally invasive and endoscopic versus open necrosectomy for necrotising pancreatitis: a pooled analysis of individual data for 1980 patients.

Objective: Minimally invasive surgical necrosectomy and endoscopic necrosectomy, compared with open necrosectomy, might improve outcomes in necrotising pancreatitis, especially in critically ill patients. Evidence from large comparative studies is lacking.

Design: We combined original and newly collected data from 15 published and unpublished patient cohorts (51 hospitals; 8 countries) on pancreatic necrosectomy for necrotising pancreatitis.

Survival outcome and prognostic factors after pancreatoduodenectomy for distal bile duct carcinoma: a retrospective multicenter study.

Purpose: Pancreatoduodenectomy is the most common operative procedure performed for distal bile duct carcinoma. Data on outcome after surgery for this rare malignancy is scarce, especially from western countries. The purpose of this study is to explore the prognostic factors and outcome after pancreatoduodenectomy for distal bile duct carcinoma.

Open Surgical versus Minimal Invasive Necrosectomy of the Pancreas-A Retrospective Multicenter Analysis of the German Pancreatitis Study Group.

Background: Necrotising pancreatitis, and particularly infected necrosis, are still associated with high morbidity and mortality. Since 2011, a step-up approach with lower morbidity rates compared to initial open necrosectomy has been established. However, mortality and complication rates of this complex treatment are hardly studied thereafter.

Parenchyma-Sparing, Limited Pancreatic Head Resection for Benign Tumors and Low-Risk Periampullary Cancer--a Systematic Review.

Background: Parenchyma-sparing local extirpation of benign tumors of the pancreatic head provides the potential benefits of preservation of functional tissue and low postoperative morbidity.

Methods: Medline/PubMed, Embase, and Cochrane library databases were surveyed for studies performing limited resection of the pancreatic head and resection of a segment of the duodenum and common bile duct or preservation of the duodenum and common bile duct (CBD). The systematic analysis included 27 cohort studies that reported on limited pancreatic head resections for benign tumors.

VEGF-releasing suture material for enhancement of vascularization: development, in vitro and in vivo study.

As it has been demonstrated that bioactive substances can be delivered locally using coated surgical suture materials, the authors developed a vascular endothelial growth factor (VEGF)-releasing suture material that should promote vascularization and potentially wound healing. In this context, the study focused on the characterization of the developed suture material and the verification of its biological activity, as well as establishing a coating process that allows reproducible and stable coating of a commercially available polydioxanone suture material with poly(l-lactide) (PLLA) and 0.1μg and 1.

Liver resections of isolated liver metastasis in breast cancer: results and possible prognostic factors.

Background. Breast cancer liver metastasis is a hematogenous spread of the primary tumour. It can, however, be the expression of an isolated recurrence.

Intensified neoadjuvant radiochemotherapy for rectal cancer enhances surgical complications.

Background: Neoadjuvant radiochemotherapy has proven superior to adjuvant treatment in reducing the rate of local recurrence without impairing cancer related survival or the incidence of distant metastases. The present study aimed at addressing the effects of an intensified protocol of neoadjuvant treatment on the development of postoperative complications.

Methods: A total of 387 patients underwent oncological resection for rectal cancer in our institution between January 2000 and December 2009.

Prognosis of rectal cancer patients improves with downstaging by intensified neoadjuvant radiochemotherapy - a matched pair analysis.

Background: Neoadjuvant radiochemotherapy has been proven superior to adjuvant treatment in reducing the rate of local recurrence without impairing cancer related survival or the incidence of distant metastases in standard protocols of neoadjuvant radiochemotherapy. The present study aimed at addressing the effects of an intensified neoadjuvant radiochemotherapy on long term cancer related and disease free survival.

Methods: A total of 387 patients underwent oncologic resection for rectal cancer in our institution between January 2000 and December 2009.

Scoring of human acute pancreatitis: state of the art.

Background: Acute pancreatitis remains as one of the most difficult and challenging digestive disorder to predict in terms of clinical course and outcome. Every case has an individual course and therefore acute pancreatitis remains challenging and fascinating. Due to this variability, many different scoring systems have evolved during the last decades.

R1 resection in pancreatic cancer has significant impact on long-term outcome in standardized pathology modified for routine use.

Background: The quality of a histopathologic workup after oncologic resection of pancreatic malignancies has changed the central role of surgery substantially for radical tumor clearance over the past years. The development of standardized protocols for pathologic workup increased the rate of R1 resections from around 20% up to 80%. In the present study, we investigated the incidence of R1 and its impact on survival after oncologic pancreatic resections using a standardized pathologic routine protocol.

Enhanced ENA-78 and IL-8 expression in patients with malignant pancreatic diseases.

Background/aim: Pancreatic cancer is characterized by perineural invasion, early lymph node and liver metastases, and an extremely dismal prognosis. In the present study we aimed at investigating the expression profile of pro-inflammatory and angiogenic CXC chemokines as potential factors contributing to the aggressive biology of this gastrointestinal malignancy.

Methods: Protein expression profiles of the CXC chemokines growth-related oncogene alpha (GRO-alpha/CXCL1), epithelial cell-derived neutrophil-activating peptide-78 (ENA-78/CXCL5), granulocyte chemoattractant protein-2 (GCP-2/CXCL6), neutrophil-activating protein-2 (NAP-2/CXCL7), and interleukin-8 (IL-8/CXCL8) were assessed by enzyme-linked immunosorbent assay in pancreatic carcinoma, cancer of the papilla of Vater, pancreatic cystadenoma, and chronic pancreatitis specimens.
