Caseload per Year in Robotic-Assisted Minimally Invasive Esophagectomy: A Narrative Review.

Esophageal surgery is deemed one of the most complex visceral operations. There is a well-documented correlation between higher caseload and better outcomes, with hospitals that perform more surgeries experiencing significantly lower mortality rates. The approach to caseload per year varies across different countries within Europe.

Robotic-assisted esophagectomy with total mesoesophageal excision enhances R0-resection in patients with esophageal cancer: A single-center experience.

Background: The focus of this research is to examine the growing use of robotic-assisted minimally invasive esophagectomy. Specifically, it evaluates the immediate clinical and cancer-related results of combining robotic-assisted minimally invasive esophagectomy with a systematic approach to total mesoesophageal excision, as opposed to traditional open transthoracic esophagectomy methods that do not employ a structured total mesoesophageal excision protocol.

Methods: A propensity score-matched analysis of 185 robotic-assisted minimally invasive esophagectomies and 223 open transthoracic esophagectomies after standardized Ivor Lewis esophagectomy was performed.

The role of cytoreductive surgery and HIPEC for the treatment of primary and secondary peritoneal malignancies-experience from a tertiary care center in Germany.

Purpose: Peritoneal surface malignancies (PSM) are commonly known to have a dismal prognosis. Over the past decades, novel techniques such as cytoreductive surgery (CRS), hyperthermic intraperitoneal chemotherapy (HIPEC), and pressurized intraperitoneal aerosol chemotherapy (PIPAC) have been introduced for the treatment of PSM which could improve the overall survival and quality of life of patients with PSM. The decision to proceed with CRS and HIPEC is often challenging due the complexity of the disease, the extent of the procedure, associated side effects, and potential risks.

Graft-versus-host disease following liver transplantation: A systematic review of literature.

Background: Graft-versus-host disease following liver transplantation is a serious and usually fatal complication. Data identifying the risk factors and specifying the diagnosis and treatment options of the disease are scarce and contentious. Moreover, recommendations for therapeutic approaches are similarly sparse.

Management of intra-thoracic anastomotic leakages after esophagectomy: updated systematic review and meta-analysis of endoscopic vacuum therapy versus stenting.

Despite a significant decrease of surgery-related mortality and morbidity, anastomotic leakage still occurs in a significant number of patients after esophagectomy. The two main endoscopic treatments in case of anastomotic leakage are self-expanding metal stents (SEMS) and the endoscopic vacuum therapy (EVT). It is still under debate, if one method is superior to the other.

Oestrogen Receptor Isoforms May Represent a Therapeutic Target in Oesophageal Adenocarcinoma.

Oesophageal adenocarcinoma is a rapidly increasing problem in which treatment options are limited. Previous studies have shown that oesophageal adenocarcinoma cells and tissues express oestrogen receptors (ERs) and show growth suppression and apoptosis in response to ER modulator agents such as tamoxifen. ERs are known to be expressed in a number of isoforms that act together to regulate cell growth and cell death.

Minor Sphincter Sparing Surgery for Successful Closure of Perianal Fistulas in Patients with Crohn's Disease.

The purpose of this study is to demonstrate that repetitive minor surgical procedures allow for a high rate of permanent closure of perianal fistulas in patients with Crohn's disease (CD). Patients with perianal fistulizing CD (PFCD) who underwent perianal surgery at the University Hospital of Muenster between 2003 and 2018 were assessed for fistula characteristics and surgical procedures. We included 45 patients (m:f = 28:17) with a mean age of 27 years at first fistula appearance.

Mutant p53 Mediates Sensitivity to Cancer Treatment Agents in Oesophageal Adenocarcinoma Associated with MicroRNA and SLC7A11 Expression.

gene mutations occur in 70% of oesophageal adenocarcinomas (OACs). Given the central role of p53 in controlling cellular response to therapy we investigated the role of mutant (mut-) p53 and SLC7A11 in a CRISPR-mediated JH-EsoAd1 knockout model. Response to 2 Gy irradiation, cisplatin, 5-FU, 4-hydroxytamoxifen, and endoxifen was assessed, followed by a TaqMan OpenArray qPCR screening for differences in miRNA expression.

Effects of therapy modifications during the last decade on the outcome of patients undergoing esophagectomy for esophageal cancer.

Background: During the last decade, numerous therapeutic regimes were assessed to improve the outcome of patients with esophageal carcinoma. We analyzed the impact of therapy alterations, including the establishment of a standardized clinical pathway and the introduction of an interdisciplinary tumor conference on the outcome of patients undergoing esophagectomy because of esophageal cancer.

Methods: Three hundred one patients were included (204 adenocarcinoma and 97 squamous cell carcinoma) who underwent an esophagectomy between 2006 and 2015.

Economic Burden of Endoscopic Vacuum Therapy Compared to Alternative Therapy Methods in Patients with Anastomotic Leakage After Esophagectomy.

Background: Endoscopic vacuum therapy (EVT) has become a promising option in the management of anastomotic leakage (AL) after esophagectomy. However, EVT is an effortful approach associated with multiple interventions. In this study, we conduct a comparative cost analysis for methods of management of AL.

Short- and Long-Term Outcomes of Different Reperfusion Sequences in Liver Transplantation.

BACKGROUND Although most centers perform primary portal vein reperfusion (PV) in orthotopic liver transplantation (OLT) for historical reasons, there is so far no sound evidence as to whether this technique is superior. The present study evaluated the long-term outcome of 3 different reperfusion sequences: PV vs primary arterial (A) vs simultaneous reperfusion (SIM). MATERIAL AND METHODS All patients at our center who underwent OLT (who received a primary, whole-organ liver graft) from 2006 to 2007 were evaluated for analysis.

Merendino Resection vs. Transhiatal Gastric Conduit After Resection of the Cardia and the Gastroesophageal Junction.

Background: Reconstruction after combined cardia resection and removal of the gastroesophageal junction can be carried out by the Merendino procedure or via a gastric conduit. This study compares postoperative complications and quality of life for both approaches.

Methods: All patients who underwent Merendino or gastric conduit reconstruction from 2011-2017 were included.

MicroRNA Profiling in Oesophageal Adenocarcinoma Cell Lines and Patient Serum Samples Reveals a Role for miR-451a in Radiation Resistance.

Many patients with Oesophageal Adenocarcinoma (OAC) do not benefit from chemoradiotherapy treatment due to therapy resistance. To better understand the mechanisms involved in resistance and to find potential biomarkers, we investigated the association of microRNAs, which regulate gene expression, with the response to individual treatments, focusing on radiation. Intrinsic radiation resistance and chemotherapy drug resistance were assessed in eight OAC cell lines, and miRNA expression profiling was performed via TaqMan OpenArray qPCR.

ABO-Incompatible Living Donor Kidney Transplantation in a Human Immunodeficiency Virus-Positive Recipient From a Human Immunodeficiency Virus-Positive Donor: A Case Report.

A human immunodeficiency virus (HIV) infection is no longer an absolute contraindication for solid organ transplantation, yet such a setting is still challenging and little explored because of general reservations and medical difficulties. We describe a 51-year-old man with end-stage renal failure due to polycystic kidney disease who underwent an ABO-incompatible kidney transplantation from his 49-year-old male partner. Early postoperative course revealed an episode of suspected acute rejection, which was successfully managed with a steroid pulse.

Management of Nonmalignant Tracheo- and Bronchoesophageal Fistula after Esophagectomy.

Background: Tracheo- or bronchoesophageal fistula (TBF) occurring after esophagectomy represent a rare but devastating complication. Management remains challenging and controversial. Therefore, the purpose of this study was to evaluate the outcome of different treatment approaches and to propose recommendations for the management of TBF.

Impact of preoperative risk factors on outcome after gastrectomy.

Background: Gastrectomy is associated with relevant postoperative morbidity. However, outcome of surgery can be improved by careful selection of patients. The objective of the current study was therefore to identify preoperative risk factors that might impact on patients' further outcome after surgical resection.
