Ghost-ileostomy versus conventional loop ileostomy in patients undergoing low anterior resection for rectal cancer: results of a randomised controlled multicentre pilot trial (DRKS00013997).

Purpose: The objective of the current pilot trial was to evaluate whether ghost ileostomy is a safe alternative to the current standard of care in terms of a conventional loop ileostomy in patients undergoing low anterior resection with total mesorectal excision (LAR/TME) for rectal cancer.

Methods: This randomized controlled pilot trial included patients undergoing LAR/TME, randomly assigning them to ghost ileostomy or conventional loop ileostomy intraoperatively. Follow-up spanned 6 months, evaluating the following endpoints: comprehensive complication index (CCI), postoperative morbidity, transformation of ghost ileostomy, presence of ostomy at 6 months, Wexner score, and quality of life (EORTC QLQ-C30 & CR29).

(1) Background: Cytoreductive surgery (CRS) with HIPEC is considered the standard of care for selected patients with peritoneal carcinomatosis, but evidence-based treatment recommendations for the therapy of peritoneal sarcomatosis are scarce. (2) Methods: We retrospectively analyzed all adult patients treated with CRS and HIPEC for peritoneal sarcomatosis between 2017 and 2024. (3) Results: Ten patients with a median age of 46.

Prospective Validation of the Pancreatic Fistula Risk Classification by the International Study Group for Pancreatic Surgery (PARIS trial).

Objective: The aim of this study was a prospective validation of the recently established ISGPS pancreas classification as a parenchymal risk classification system for pancreatic fistula after pancreatoduodenectomy.

Summary Background Data: Postoperative pancreatic fistula (POPF) is the major driver for complications after partial pancreatoduodenectomy (PD). Recently, the International Study Group for Pancreatic Surgery (ISGPS) published a pancreas classification containing the parameters main pancreatic duct diameter (MPD) and pancreatic texture to help assess the risk of POPF development following pancreatoduodenectomy.

Postoperative Complications and Mobilization Following Major Abdominal Surgery With Versus Without Fitness Tracker-based Feedback (EXPELLIARMUS): A Student-led Multicenter Randomized Controlled Clinical Trial of the CHIR-Net SIGMA Study Group.

Objective: To determine whether daily postoperative step goals and feedback through a fitness tracker (FT) reduce the rate of postoperative complications after surgery.

Background: Early and enhanced postoperative mobilization has been advocated to reduce postoperative complications, but it is unknown whether FT alone can reduce morbidity.

Methods: EXPELLIARMUS was performed at 11 University Hospitals across Germany by the student-led clinical trial network SIGMA.

[Cancer of the Esophagogastric Junction: Double Tract Reconstruction - Evidence and Technique].

Adenocarcinoma of the esophagogastric junction (AEG) still represent a certain surgical challenge. In contrary to the trend of thoracoabdominal surgery for AEG I and AEG II cancer, the proximal gastrectomy is regaining popularity through new reconstruction methods such as the double tract reconstruction. Proximal gastrectomy followed by double tract reconstruction represents an alternative for the thoracoabdominal approach for suitable AEG II cancer and an alternative to the total gastrectomy for AEG III cancers.

Robotic versus open partial pancreatoduodenectomy (EUROPA): a randomised controlled stage 2b trial.

Background: Open partial pancreatoduodenectomy (OPD) represents the current gold standard of surgical treatment of a wide range of diseases of the pancreatic head but is associated with morbidity in around 40% of cases. Robotic partial pancreatoduodenectomy (RPD) is being used increasingly, yet, no randomised controlled trials (RCTs) of RPD versus OPD have been published, leaving a low level of evidence to support this practice.

Methods: This investigator-initiated, exploratory RCT with two parallel study arms was conducted at a high-volume pancreatic centre in line with IDEAL recommendations (stage 2b).

Intraoperative Wound Irrigation for the Prevention of Surgical Site Infection After Laparotomy: A Randomized Clinical Trial by CHIR-Net.

Importance: Surgical site infections frequently occur after open abdominal surgery. Intraoperative wound irrigation as a preventive measure is a common practice worldwide, although evidence supporting this practice is lacking.

Objective: To evaluate the preventive effect of intraoperative wound irrigation with polyhexanide solution.

Long-term recurrence-free survival following pancreatic surgery with HIPEC treatment for locally advanced pancreatic adenocarcinoma.

More than 5 years previous to this report, a female patient in her 60s underwent oncological left-sided pancreatic resection and adrenalectomy including splenectomy for locally advanced pancreatic adenocarcinoma (PDAC), recommended by a multidisciplinary tumour board (MDT). Additionally, she was treated with gemcitabine-containing hyperthermic intraperitoneal chemotherapy (HIPEC) for 60 minutes in the framework of a clinical trial (PanHIPEC), aiming to determine the safety and feasibility (not efficacy) of this approach. Following the postoperative MDT recommendation, she subsequently received adjuvant chemotherapy consisting of six cycles of gemcitabine and cisplatin for a histopathologically confirmed PDAC of the pancreatic tail with infiltration of the left-sided adrenal gland (pT3, pN1 (3/16), cM0, L0, V0, Pn1, R0, G2).

Results of robotic liver surgery in association with IWATE criteria - the first 100 cases.

Background: Aim of the current study was to present the results of the implementation phase of a robotic liver surgery program and to assess the validity of the IWATE difficulty score in predicting difficulty and postoperative complications in robotic liver surgery.

Methods: Based on the prospective database of the Interdisciplinary Robotic Center of Ulm University Hospital, the first 100 robotic liver surgeries were identified and analyzed. Perioperative parameters (duration of surgery and blood loss) and postoperative parameters including morbidity, mortality, and length of hospital stay were assessed and the results were compared between different IWATE difficulty categories.

Efficacy of Different Oncolytic Vaccinia Virus Strains for the Treatment of Murine Peritoneal Mesothelioma.

Effective treatment options for peritoneal surface malignancies (PSMs) are scarce. Oncolytic virotherapy with recombinant vaccinia viruses might constitute a novel treatment option for PSM. We aimed to identify the most effective oncolytic vaccinia virus strain in two murine mesothelioma cell lines and the oncolytic potential in a murine model of peritoneal mesothelioma.

Prevention of incisional hernia with prophylactic onlay and sublay mesh reinforcement vs. primary suture only in midline laparotomies (PRIMA): long-term outcomes of a multicentre, double-blind, randomised controlled trial.

Background: Incisional hernia occurs approximately in 40% of high-risk patients after midline laparotomy. Prophylactic mesh placement has shown promising results, but long-term outcomes are needed. The present study aimed to assess the long-term incisional hernia rates of the previously conducted PRIMA trial with radiological follow-up.

Intraoperative bacterial cultures fail to reliably predict the bacterial spectrum encountered during infectious complications after appendicitis.

Acute appendicitis is a common surgical emergency. Complicated appendicitis usually warrants perioperative antibiotic treatment in order to prevent infectious complications. Whether routine microbiological testing benefits the individual patient is a topic of debate.

Development of individual competencies and team performance in interprofessional ward rounds: results of a study with multimodal observations at the Heidelberg Interprofessional Training Ward.

Introduction: Interprofessional training wards (IPTW) aim to improve undergraduates' interprofessional collaborative practice of care. Little is known about the effects of the different team tasks on IPTW as measured by external assessment. In Heidelberg, Germany, four nursing and four medical undergraduates (= one cohort) care for up to six patients undergoing general surgery during a four-week placement.

Conventional partial pancreatoduodenectomy versus an extended pancreatoduodenectomy (triangle operation) for pancreatic head cancers-study protocol for the randomised controlled TRIANGLE trial.

Background: Pancreatic ductal carcinoma (PDAC) is the fourth most frequent cause of cancer-related death in the Western world, and its incidence is rising. In patients that undergo curative resection, local recurrence (LR) is frequent. A recently described surgical technique of extended pancreatoduodenectomy (PD) termed the TRIANGLE operation has been proposed as a promising approach to reduce LR and improve disease-free survival in PDAC patients.

[Measuring individual competencies and team performance in clinical learning settings of interprofessional collaborative practice: Empirical development of the Interprofessional Ward Round Individual and Team Assessment Tool (IP-VITA)].

Background: Interprofessional training wards (IPTW) can contribute to the development of interprofessional competencies. In order to evaluate the acquisition of competencies, instruments are needed that record both team performance and individual competencies in the clinical teaching setting in third-party assessment. This paper describes the Interprofessional Ward Round Individual and Team Assessment-Tool, IP-VITA ("Interprofessionelle Visiten Individual und Team Assessment Tool") and its development.

How do former medical and nursing undergraduates describe their learning on an interprofessional training Ward 12-18 months later? - A retrospective qualitative analysis.

Background: Interprofessional training wards (IPTWs) seem to deliver good results in terms of development of interprofessional competencies. However, evidence of long-term effects of these training wards on learners' competency development is lacking and little is known about retrospective evaluation of IPTWs. Therefore, this study aimed to explore the retrospective evaluation of competency development and interprofessional collaboration of former undergraduates 12 or more months after a placement on an IPTW.

Overall morbidity after total minimally invasive keyhole oesophagectomy versus hybrid oesophagectomy (the MICkey trial): study protocol for a multicentre randomized controlled trial.

Background: Oesophageal cancer (EC) is the sixth leading cause of cancer death worldwide. Oesophageal resection is the only curative treatment option for EC which is frequently performed via an abdominal and right thoracic approach (Ivor-Lewis operation). This 2-cavity operation is associated with a high risk of major complications.

Prophylactic effect of retromuscular mesh placement during loop ileostomy closure on incisional hernia incidence-a multicentre randomised patient- and observer-blind trial (P.E.L.I.O.N trial).

Background: Incisional hernia is a frequent complication following loop ileostomy reversal. Incisional hernias are associated with morbidity, loss of health-related quality of life and costs and warrant the investigation of prophylactic measures. Prophylactic mesh implantation at the time of surgical stoma reversal has shown to be a promising and safe method to prevent incisional hernias in this setting.

Impact of perioperative steroid administration in patients undergoing elective liver resection: meta-analysis.

Background: Perioperative steroid administration may improve postoperative outcomes in major abdominal surgery by reducing the systemic inflammatory response. The aim of this systematic review was to evaluate the impact of perioperative steroid administration on outcomes after elective liver resection.

Methods: PubMed, Cochrane Library, and Web of Science were systematically searched for randomized clinical trials (RCTs) comparing perioperative steroid administration with placebo, standard of care, or no steroids with respect to postoperative outcomes, particularly postoperative complications.

Measuring patient centeredness with German language Patient-Reported Experience Measures (PREM)-A systematic review and qualitative analysis according to COSMIN.

Background: Patient centeredness is an integral part of the quality of care. Patient-reported experience measures (PREMs) are assumed to be an appropriate tool to assess patient-centredness. An evaluation of German-speaking PREMs is lacking.

Induction Chemotherapy with FOLFIRINOX for Locally Advanced Pancreatic Cancer: A Simple Scoring System to Predict Effect and Prognosis.

Background: Effective chemotherapy (CTx) protocols as induction treatment provide increasing opportunities for surgical resection of locally advanced pancreatic cancer (LAPC). Although improved survival after resection of LAPC with CTx has been reported for selected patients, reliable recommendations on the indication for conversion surgery after induction treatment are currently lacking. We investigated the factors predictive of prognosis in resected LAPC after FOLFIRINOX.

Top 10 research priorities in colorectal cancer: results from the Colorectal Cancer Priority-Setting Partnership.

Background: Colorectal cancer (CRC) is the third most frequent cause of cancer death in the word. Which aspects of research into CRC should be accorded the highest priority remains unclear, because relevant stakeholders, such as patients, nurses, and physicians, played hardly any part in the development of research projects. The goal in forming the CRC Priority-Setting Partnership (PSP) was to bring all relevant stakeholders together to identify and prioritize unresolved research questions regarding the diagnosis, treatment, and follow-up of CRC.

Protocol of a prospective study investigating the association of PAncreatic parenchymal RISk factors with postoperative pancreatic fistula after partial pancreaticoduodenectomy (PARIS trial).

Introduction: Partial pancreatoduodenectomy (PD) is the treatment of choice for many malignant and benign diseases of the pancreatic head. Postoperative complication rates of up to 40% are regularly reported. One of the most common and potentially life-threatening complication is the postoperative pancreatic fistula (POPF).

[Patient-centeredness].

Background: Patient-centeredness has developed into the guiding principle of healthcare policy over the last decade. However, its practical implementation is hindered by numerous problems and opposing interests.

Objective: To define and elucidate the term patient-centeredness, describe evidence-based measurement tools and outline recommendations for practical implementation.

Clinical outcomes of patients treated on the Heidelberg interprofessional training ward vs. care on a conventional surgical ward: A retrospective cohort study.

Interprofessional training wards (IPTW) are a form of interprofessional education enabling trainees of different healthcare professions to work together in teams. Concerns about patient safety are a major barrier to the implementation of IPTWs. The objective of this retrospective study was to analyze patient relevant clinical outcomes on Germany's first IPTW (; HIPSTA) in the Department of Surgery at University Hospital Heidelberg in comparison to a conventional surgical ward (CSW).
