Genome-wide analysis of 944 133 individuals provides insights into the etiology of haemorrhoidal disease.

Objective: Haemorrhoidal disease (HEM) affects a large and silently suffering fraction of the population but its aetiology, including suspected genetic predisposition, is poorly understood. We report the first genome-wide association study (GWAS) meta-analysis to identify genetic risk factors for HEM to date.

Design: We conducted a GWAS meta-analysis of 218 920 patients with HEM and 725 213 controls of European ancestry.

Learning Laparoscopic Surgery Skills With a 4K Ultra-High Definition 2D vs a Three-Dimensional HD Laparoscopic System: Results From a Prospective Randomized Trial.

. In minimally invasive surgery (MIS), the loss of stereoscopic depth perception in a two-dimensional (2D) representation is most challenging. Recently introduced 4K ultrahigh definition (UHD) 2D optical systems could potentially facilitate the learning and use of compensation mechanisms for the loss of depth perception.

Testing Distinct Three-Dimensional Effects in Laparoscopy: A Prospective Randomized Trial Using the Lübecker Toolbox Curriculum.

Background: The use of stereoscopic laparoscopic systems in minimally invasive surgery (MIS) allows a three-dimensional (3D) view of the surgical field, which improves hand-eye coordination. Depending on the stereo base used in the construction of the endoscopes, 3D systems may differ regarding the 3D effect. Our aim was to investigate the influence of different stereo bases on the 3D effect.

Efficacy of goal-directed minimally invasive surgery simulation training with the Lübeck Toolbox-Curriculum prior to first operations on patients: Study protocol for a multi-centre randomized controlled validation trial (NOVICE).

Background: Minimally invasive surgery (MIS) procedures require special psychomotoric skills. Learning of these MIS basic skills is often performed in the operating room (OR). This is economically inefficient and could be improved in terms of patient safety.

[Surgical Management of Advanced Haemorrhoid Disease - What's the Deal?].

About 2 - 3 million patients suffer from haemorrhoid disease in Germany each year. Advanced haemorrhoid disease is assumed if an operation is planned. In Germany, approximately 50,000 operations per year are performed for haemorrhoids.

Influence of Anastomotic Leak After Elective Colorectal Cancer Resection on Survival and Local Recurrence: A Propensity Score Analysis.

Background: The occurrence of anastomotic leakage is still a life-threatening complication for patients after colorectal surgery. In literature not only an impact on the short-term outcome but also on long-term survival and local recurrence of colorectal cancer patients is discussed.

Objective: This study aimed to investigate the impact of anastomotic leakage on long-term survival and local recurrence.

Video Tutorials Increase Precision in Minimally Invasive Surgery Training - a Prospective Randomised Trial and Follow-up Study.

Background: Simulation-based practice has become increasingly important in minimally invasive surgery (MIS) training. Nevertheless, personnel resources for demonstration and mentoring simulation-based practice are limited. Video tutorials could be a useful tool to overcome this dilemma.

Surgical management of complicated rectovaginal fistulas and the role of omentoplasty.

Background: Patients with rectovaginal fistulas have a significantly reduced quality of life. Therefore, surgical therapy is often needed even in palliative cases. The aim of the present study was to perform an analysis of the results of the different treatment options available today.

Conception of the Lübeck Toolbox curriculum for basic minimally invasive surgery skills.

Purpose: Difficulties at the beginning of the learning curve in minimally invasive surgery (MIS) can well be overcome by simulation outside the operating room. Despite a great number of available devices, standardized, structured, and validated training curricula for video simulators are scarce.

Methods: The Lübeck Toolbox (LTB) video trainer provides six training modules and online video tutorials.

[Implementation of a Laparoscopic Simulation Training in Undergraduate Medical Education - The Lübeck Toolbox-Curriculum].

Background: Simulation-based training has become increasingly relevant in minimally invasive surgery (MIS). It is unclear whether or not the established Lübeck Toolbox (LTB) Curriculum for the acquisition of basic MIS skills can be implemented to supplement standard undergraduate education in surgery and how it would be accepted.

Materials Und Methods: Since 04/2015, students at the medical school of the University of Lübeck have had the option to complete the highly standardized and validated LTB Curriculum.

Laparoscopic resection of right colon cancer-a matched pairs analysis.

Purpose: Laparoscopy for colorectal cancer resection bares early post-operative advantages and results in equal oncologic long-term outcome. However, data on laparoscopic right hemi-colectomy is scarce. Aim of the present study was to analyze a well selected collective of patients with right-sided colon cancer treated open and laparoscopically with regard to peri-operative and long-term outcome.

Laparoscopy for bowel obstruction--a contradiction? Results of a multi-institutional survey in Germany.

Purpose: The purpose of the present study was to investigate on the acceptance and frequency of laparoscopic surgery for the management of acute and chronic bowel obstruction in a general patient population in German hospitals.

Methods: To receive an authoritative opinion on laparoscopic treatment of bowel obstruction in Germany, a cross-sectional online study was conducted. We designed an online-based survey, supported by the German College of Surgeons (Berufsverband der Deutschen Chirurgen, BDC) to get multi-institutional-based data from various level providers of patient care.

Cold-Plasma Coagulation on the Surface of the Small Bowel Is Safe in Pigs.

Introduction: Surgical treatment in patients with peritoneal carcinomatosis is often limited by the extent of small bowel involvement. We investigated the results of the application of cold-plasma coagulation on the surface of the small bowel.

Methods: After permission by the federal government of Schleswig-Holstein, 8 female pigs underwent a laparoscopy and cold-plasma coagulation on the small bowel with different energy levels.

Stage-specific frequency and prognostic significance of aneuploidy in patients with sporadic colorectal cancer--a meta-analysis and current overview.

Purpose: Aneuploidy has long been suggested as an independent prognostic marker for colorectal cancer (CRC) patients and could thus aid for individualized medicine. However, due to a large spectrum of deviating studies, expert panels do not recommend ploidy assessment. In order to clarify a potential bias of stage-specific frequency of aneuploidy, we now conducted a meta-analysis combined with a systematic review regarding aneuploidy and prognosis.

Colorectal neoplasia in IBD--a single-center analysis of patients undergoing proctocolectomy.
