Impact of Positive Lymph Nodes after Systematic Perihilar Lymphadenectomy in Colorectal Liver Metastases.

25 to 50% of patients suffering from colorectal cancer develop liver metastases. The incidence of regional lymph node (LN) metastases within the liver is up to 14%. The need for perihilar lymph node dissection (LND) is still a controversial topic in patients with colorectal liver metastases (CRLM).

The short- and long-term outcome after the surgical management of common bile duct stones in a tertiary referral hospital.

Background: The removal of common bile duct stones by endoscopic retrograde cholangiopancreatography (ERCP) shows excellent results with low complication rates and is therefore considered a gold standard. However, in case of stones non-removable by ERCP, surgical extraction is needed. The surgical approach is still controversial and clinical guidelines are missing.

High ratio of pCXCR4/CXCR4 tumor infiltrating immune cells in primary high grade ovarian cancer is indicative for response to chemotherapy.

Background: Ovarian cancer (OC) is the fifth most common malignant female cancer with a high mortality, mainly because of aggressive high-grade serous carcinomas (HGSOC), but also due to absence of specific early symptoms and effective detection strategies. The CXCL12-CXCR4 axis is considered to have a prognostic impact and to serve as potential therapeutic target. Therefore we investigated the role of pCXCR4 and CXCR4 expression of the tumor cells and of tumor infiltrating immune cells (TIC) in high-grade serous OC and their association with the recurrence-free (RFS) and overall survival (OS).

Impact of Oncoplastic Breast Surgery on Rate of Complications, Time to Adjuvant Treatment, and Risk of Recurrence.

Background: The aim of this study was to compare the risk of complications and recurrence between oncoplastic and conventional breast surgery.

Methods: This is a retrospective analysis of a consecutive series of 436 patients with stage I-III breast cancer who underwent surgery at the University Hospital of Basel between 2011 and 2018.

Longterm outcome of anal fistula - A retrospective study.

This retrospective observational study analyses the outcomes of patients undergoing surgery for anal fistula at a single centre in order to assess recurrence and re-operation rates after different surgical techniques. During January 2005 and May 2013, all patients with anal fistula were included. Baseline characteristics, details of presentation, fistula anatomy, type of surgery, post-surgical outcomes and follow-up data were collected.

Teaching in the operating room: A risk for surgical site infections?

Background/aim: To investigate whether teaching procedures and surgical experience are associated with surgical site infection (SSI) rates.

Methods: This prospective cohort study of patients undergoing general, orthopedic trauma and vascular surgery procedures was done between 2012 and 2015 at two tertiary care hospitals in Switzerland/Europe.

Results: Out of a total of 4560 patients/surgeries, 1403 (30.

High density of CD66b in primary high-grade ovarian cancer independently predicts response to chemotherapy.

Purpose: Ovarian carcinoma (OC) is the most lethal female genital cancer. After a primary curative surgical approach followed by chemotherapy, a fraction of the patients recur with chemoresistant disease. Data indicate a favorable therapeutic effect of tumor-infiltrating neutrophils (TIN) in OC.

The role of CRP and Pentraxin 3 in the prediction of systemic inflammatory response syndrome and death in acute pancreatitis.

Pentraxin 3 (PTX3) is an acute phase protein. Our goal was to assess PTX3 as a predictor of systemic inflammatory response syndrome (SIRS), death and disease severity in acute pancreatitis (AP) in comparison to C-reactive protein (CRP) and the APACHE II score. From April 2011 to January 2015, 142 patients with AP were included in this single center post hoc analysis of prospectively collected data at the University Hospital Basel, Switzerland.

The impact of surgical site infections on hospital contribution margin-a European prospective observational cohort study.

Background: Surgical site infections (SSIs) are common surgical complications that lead to increased costs. Depending on payer type, however, they do not necessarily translate into deficits for every hospital.

Objective: We investigated how surgical site infections (SSIs) influence the contribution margin in 2 reimbursement systems based on diagnosis-related groups (DRGs).

Nectin-4 Expression Is an Independent Prognostic Biomarker and Associated With Better Survival in Triple-Negative Breast Cancer.

Triple-negative breast cancer (TNBC) represents about 10-20% of all invasive breast cancers and is associated with a poor prognosis. The nectin cell adhesion protein 4 (Nectin-4) is a junction protein involved in the formation and maintenance of cell junctions. Nectin-4 has previously shown to be expressed in about 60% of TNBC as well as in TNBC metastases, but to be absent in normal breast tissue, which makes it a potential specific target for TNBC therapy.

Endoscopic Superficialisation of Haemodialysis Arteriovenous Fistulas in Obese Patients - Safety, Feasibility, and Outcomes.

Objective: The aim was to evaluate the safety and feasibility of endoscopic superficialisation (ES) in patients with deeply located cephalic veins in well matured arteriovenous fistulae (AVF) and to present functional outcomes.

Methods: All patients with cannulation difficulties due to a deep lying cephalic vein of more than 6 mm but with an otherwise matured AVF with a straight needle access segment of at least 6 cm were included in this retrospective study. Procedure related safety, defined as completion of ES with no need for conversion to open surgery, and feasibility in terms of cephalic vein depth reduction were assessed.

Antimicrobial Prophylaxis Redosing Reduces Surgical Site Infection Risk in Prolonged Duration Surgery Irrespective of Its Timing.

Background: Long-duration surgery requires repeated administration of antimicrobial prophylaxis (amp). Amp "redosing" reduces incidence of surgical site infections (SSI) but is frequently omitted. Clinical relevance of redosing timing needs to be investigated.

Infiltration by myeloperoxidase-positive neutrophils is an independent prognostic factor in breast cancer.

Purpose: Myeloperoxidase (MPO) is an enzyme secreted by neutrophil granulocytes as a result of phagocytosis during inflammation. In colorectal cancer, tumour infiltration by MPO expressing cells has been shown to be independently associated with a favourable prognosis. In this study, we explored the role of MPO-positive cell infiltration and its prognostic significance in invasive breast cancer.

Perioperative major adverse cardiac events in urgent femoral artery repair after coronary stenting are less common than previously reported.

Objective: Noncardiac surgery early after coronary stenting has been associated with a high rate of stent thrombosis and catastrophic outcomes. However, those outcomes were mostly seen when dual antiplatelet therapy (DAPT) was discontinued before surgery. This observational study sought to estimate the risk of major adverse cardiac events (MACEs) after femoral artery repair following recent stent-percutaneous coronary intervention under continued DAPT and to explore potential risk factors.

Expression of RET is associated with Oestrogen receptor expression but lacks prognostic significance in breast cancer.

Background: The Rearranged during Transfection (RET) protein is overexpressed in a subset of Estrogen Receptor (ER) positive breast cancer, with both signalling pathways functionally interacting. This cross-talk plays a pivotal role in the resistance of breast cancer cells to anti-endocrine therapies, and RET expression is assumed to correlate with poor prognosis based on findings in small patient cohorts. The aim of our study was to investigate the impact of RET expression on patient outcome in human breast cancer.

Oncoplastic Breast Consortium consensus conference on nipple-sparing mastectomy.

Purpose: Indications for nipple-sparing mastectomy (NSM) have broadened to include the risk reducing setting and locally advanced tumors, which resulted in a dramatic increase in the use of NSM. The Oncoplastic Breast Consortium consensus conference on NSM and immediate reconstruction was held to address a variety of questions in clinical practice and research based on published evidence and expert panel opinion.

Methods: The panel consisted of 44 breast surgeons from 14 countries across four continents with a background in gynecology, general or reconstructive surgery and a practice dedicated to breast cancer, as well as a patient advocate.

Associations of Hospital Length of Stay with Surgical Site Infections.

Background: Surgical site infections (SSI) are a major cause of morbidity and mortality in surgical patients. Postoperative and total hospital length of stay (LOS) are known to be prolonged by the occurrence of SSI. Preoperative LOS may increase the risk of SSI.

Impact of a Surgical Sealing Patch on Lymphatic Drainage After Axillary Dissection for Breast Cancer: The SAKK 23/13 Multicenter Randomized Phase III Trial.

Background: Several studies and a meta-analysis showed that fibrin sealant patches reduced lymphatic drainage after various lymphadenectomy procedures. Our goal was to investigate the impact of these patches on drainage after axillary dissection for breast cancer.

Methods: In a phase III superiority trial, we randomized patients undergoing breast-conserving surgery at 14 Swiss sites to receive versus not receive three large TachoSil patches in the dissected axilla.

The association of surgical drains with surgical site infections - A prospective observational study.

Background: Surgical drains are widely used despite limited evidence in their favor. This study describes the associations between drains and surgical site infections (SSI).

Methods: This prospective observational double center study was performed in Switzerland between February 2013 and August 2015.

High-resolution standardization reduces delay due to workflow disruptions in laparoscopic cholecystectomy.

Background: Optimal resource utilization in high-cost environments like operating theatres is fundamental in today's cost constrained health care systems. Interruptions of the surgical workflow, i.e.

The role of preoperative blood parameters to predict the risk of surgical site infection.

Background: Routine preoperative blood work is not recommended but selected biochemical markers may predict the risk of surgical site infection (SSI). This study examines the association between preoperative biochemical markers and the risk of SSI.

Methods: This observational cohort study, nested in a randomized controlled trial, was conducted at two tertiary referral centers in Switzerland.

Current standards in oncoplastic breast conserving surgery.

Oncoplastic breast conserving surgery is increasingly used to treat patients with breast cancer. In the absence of randomized data, a large body of observational evidence consistently indicates low rates of recurrence and high rates of survival, but points to a higher rate of complications compared to conventional breast conserving surgery. Established goals of oncoplastic breast conserving surgery are to broaden the indication for breast conservation towards larger tumors, and to improve esthetic outcomes.

Timing of surgical antimicrobial prophylaxis: a phase 3 randomised controlled trial.

Background: Based on observational studies, administration of surgical antimicrobial prophylaxis (SAP) for the prevention of surgical site infection (SSI) is recommended within 60 min before incision. However, the precise optimum timing is unknown. This trial compared early versus late administration of SAP before surgery.
