Cost analysis of laparoscopic total versus open total gastrectomy in gastric cancer.

Purpose: Despite ongoing discussions concerning clinical equivalence of laparoscopic total gastrectomy (LTG) compared to open total gastrectomy (OTG) in gastric cancer (GC) surgery, complementary evidence regarding financial implications is sparse. The aim of this study was to compare hospital associated expenses and perioperative outcomes between both approaches.

Methods: Clinicopathological and financial data from 80 consecutive GC patients undergoing LTG or OTG between 2015 and 2022 were investigated.

Textbook outcome after robotic and laparoscopic Ivor Lewis esophagectomy is associated with improved survival: A propensity score-matched analysis.

Background: Esophagectomy is central to curative therapy for esophageal cancer (EC). Perioperative outcomes affect both disease-free survival (DFS) and overall survival (OS) in patients undergoing oncologic esophageal surgery. The adoption of robotic techniques may improve surgical outcomes; however, the complex nature of perioperative outcomes is not adequately captured by individual quality measures.

Enhancing Preoperative Outcome Prediction: A Comparative Retrospective Case-Control Study on Machine Learning versus the International Esodata Study Group Risk Model for Predicting 90-Day Mortality in Oncologic Esophagectomy.

Risk prediction prior to oncologic esophagectomy is crucial for assisting surgeons and patients in their joint informed decision making. Recently, a new risk prediction model for 90-day mortality after esophagectomy using the International Esodata Study Group (IESG) database was proposed, allowing for the preoperative assignment of patients into different risk categories. However, given the non-linear dependencies between patient- and tumor-related risk factors contributing to cumulative surgical risk, machine learning (ML) may evolve as a novel and more integrated approach for mortality prediction.

Emergency surgery influences oncological outcome in small intestinal neuroendocrine tumors.

Background And Aims: Patients with small intestinal neuroendocrine tumors (siNETs) frequently present emergently due to bowel ischemia or bowel obstruction. The influence of emergency surgery on the prognosis of siNET remains controversial. The aim of this study was to investigate the association between type of presentation (emergency/elective) and oncological outcome.

[Position paper of the Berlin-Brandenburg Surgical Society-On the future of surgical further training].

Background: Surgical further training faces the challenging task of reconciling technological advancements and patient safety, particularly in the context of the planned hospital reform. Additionally, the generation shift and evolving expectations of Generations Y and Z in the workplace present further challenges. In response to these demands, the Berlin-Brandenburg Surgical Society (Berlin-Brandenburgische Chirurgische Gesellschaft, BCG) initiated a structured discussion and developed a position paper during the Neuhardenberg talks (Neuhardenberger Gespräche).

The Impact of the COVID-19 Pandemic on Esophageal and Gastric Cancer Surgery in Germany: A Four-Year Retrospective Single-Center Study of 287 Patients.

Disruptions to surgical care for cancer patients during the COVID-19 pandemic remain an ongoing debate. This study assesses the effects of the COVID-19 pandemic on perioperative outcomes in a continuous series of surgically treated esophageal and gastric carcinoma patients at a large university hospital in Europe over 48 months. We conducted a retrospective single-center cohort study at a tertiary referral center.

Influence of Lymphatic, Microvascular and Perineural Invasion on Oncological Outcome in Patients with Neuroendocrine Tumors of the Small Intestine.

For the histopathological work-up of resected neuroendocrine tumors of the small intestine (siNET), the determination of lymphatic (LI), microvascular (VI) and perineural (PnI) invasion is recommended. Their association with poorer prognosis has already been demonstrated in many tumor entities. However, the influence of LI, VI and PnI in siNET has not been sufficiently described yet.

Robotic-Assisted Ivor Lewis Esophagectomy Is Safe and Cost Equivalent Compared to Minimally Invasive Esophagectomy in a Tertiary Referral Center.

In recent decades, robotic-assisted minimally invasive esophagectomy (RAMIE) has been increasingly adopted for patients with esophageal cancer (EC) or cancer of the gastroesophageal junction (GEJ). However, concerns regarding its costs compared to conventional minimally invasive esophagectomy (MIE) have emerged. This study examined outcomes and costs of RAMIE versus total MIE in 128 patients who underwent Ivor Lewis esophagectomy for EC/GEJ at our department between 2017 and 2021.

Textbook Outcome after Gastrectomy for Gastric Cancer Is Associated with Improved Overall and Disease-Free Survival.

(1) Background: The complexity of the perioperative outcome for patients with gastric cancer is not well reflected by single quality metrics. To study the effect of the surgical outcome on survival, we have evaluated the relationship between textbook outcome (TO)-a new composite parameter-and oncological outcome. (2) Methods: All patients undergoing total gastrectomy or trans-hiatal extended gastrectomy for gastric cancer with curative intent between 2017 and 2021 at our institution were included.

Prognostic differences in grading and metastatic lymph node pattern in patients with small bowel neuroendocrine tumors.

Purpose: Neuroendocrine tumors of the small intestine (si-NET) describe a heterogenous group of neoplasms. Based on the Ki67 proliferation index si-NET are divided into G1 (Ki67 < 2%), G2 (Ki67 3-20%) and rarely G3 (Ki67 > 20%) tumors. However, few studies evaluate the impact of tumor grading on prognosis in si-NET.

Surgical Approach to Liver Metastases in GEP-NET in a Tertiary Reference Center.

Indications for liver resection in patients with gastroenteropancreatic neuroendocrine tumors (GEP-NET) vary from liver resection with curative intent to tumor debulking or tissue sampling for histopathological characterization. With increasing expertise, the number of minimally invasive liver surgeries (MILS) in GEP-NET patients has increased. However, the influence on the oncological outcome has hardly been described.

The Learning Curve for Hand-Assisted Laparoscopic Total Gastrectomy in Gastric Cancer Patients.

(1) Background: Hand-assisted laparoscopic total gastrectomy (LTG) for patients with gastric cancer (GC) has been established as the standard surgical treatment at our center. This study aims to quantify the learning curve for surgeons performing minimally invasive total gastrectomy at a high-volume single center. (2) Methods: One hundred and eighteen consecutive patients who underwent minimally invasive total gastrectomy between January 2014 and December 2020 at a single high-volume center were included and reviewed retrospectively.

The Association between Neoadjuvant Radio-Chemotherapy and Prolonged Healing of Anastomotic Leakage after Esophageal Resection Treated with EndoVAC Therapy.

(1) Background: Endoscopic vacuum therapy (EVT) has become the mainstay in the treatment of early anastomotic leakage (AL) after esophageal resection. The effect of nRCT on the efficacy of EVT is currently unknown. (2) Methods: Data of 427 consecutive patients undergoing minimally invasive esophagectomy between 2013 and 2022 were analyzed.

[Peritoneal carcinomatosis of gastric cancer : Treatment options for peritoneal carcinomatosis of gastric cancer].

Background: Gastric cancer is one of the most aggressive malignant diseases of the gastrointestinal tract with a high rate of metastasis. Peritoneal metastasis occurs in up to 60% of all patients and synchronously in up to 30% in locally advanced gastric cancer. Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) have been an established treatment option in selected patients for several years, as the HIPEC serves as an alternative administration route.

The challenge to differentiate between sarcoma or adrenal carcinoma-an observational study.

Background: Adrenal sarcomas are rare malignant tumors with structural and clinical similarities to sarcomatoid adrenocortical carcinoma. Preoperative diagnosis of tumors of the adrenal gland can be challenging and often misleading thus detaining patients from appropriate oncological strategies.

Objective: This analysis of a case series evaluated the predictive capability of the primary clinical diagnosis in case of malignancies of the adrenal gland.

Orthotopic Liver Transplantation for Budd-Chiari Syndrome: Observations from a 30-Year Liver Transplant Program.

Budd-Chiari syndrome (BCS) refers to a complete thrombotic obstruction of the venous hepatic outflow tract due to various etiologies and constitutes a rare indication for ortothopic liver transplantation (LT). Few studies investigated long-term outcomes after LT for BCS. The aim of this study was to examine potential risk factors for late mortality and to evaluate long-term outcomes after LT for BCS.

Clinical and Histological Long-Term Follow-Up of De Novo HBV-Infection after Liver Transplantation.

: Development of hepatitis-B is considered a serious complication after liver transplantation. HBV de novo infection is a rather rare phenomenon, however it deserves attention in the era of donor organ shortage. The aim of the present analysis was to examine its course in liver transplant patients.

Discontinuation of Passive Immunization Is Safe after Liver Transplantation for Combined HBV/HDV Infection.

Patients after LT due to combined HBV/HDV infection are considered to be high-risk patients for recurrence of hepatitis B and D. To date, life-long prophylaxis with hepatitis B immunoglobulin (HBIG) and replication control with nucleos(t)ide analogs (NA) remains standard. We examined the course of 36 patients that underwent liver transplantation from 1989 to 2020 for combined HBV/HDV-associated end-stage liver disease in this retrospective study.

Speckle Tracking Analysis Reveals Altered Left Atrial and Ventricular Myocardial Deformation in Patients with End-Stage Liver Disease.

Background: Cardiac function can be influenced by liver cirrhosis and should be thoroughly evaluated before liver transplantation. We investigated left ventricular (LV) and, for the first time, left atrial (LA) strain and strain rate in end-stage liver cirrhosis patients of different etiologies.

Methods: This retrospective, cross-sectional study evaluated left heart function in 80 cirrhosis patients and 30 controls using standardized echocardiographic techniques and speckle tracking technology (STE) analysis.

Insulinoma in pregnancy (a case presentation and systematic review of the literature).

Insulinomas are rare, benign and functional tumors that coincidentally may become overt during pregnancy or in the post-partum period. As the general symptoms of a pregnancy might cover the clinical presentation, diagnosing remains challenging. We present one additional case of a post-partum insulinoma, combined with a systematic review of the literature to sum up relevant details in diagnosis and treatment.

Long-term Outcome of Orthotopic Liver Transplantation in Patients With Hemochromatosis: A Summary of a 30-year Transplant Program.

Unlabelled: Hemochromatosis (HC) is an autosomal recessive disease characterized by impaired iron metabolism and a rare indication for orthotopic liver transplantation (LT). Data about iron reaccumulation and remodeling of the liver graft after LT are limited. Therefore, we performed an evaluation of the histopathologic changes during long-term follow-up in patients with HC.

Association between obesity after liver transplantation and steatosis, inflammation, and fibrosis of the graft.

Background: Nonalcoholic steatohepatitis has become one of the leading causes of liver transplantation. The development of steatosis, as well as the link to inflammation and fibrosis, after transplantation remain poorly understood. The aim of this analysis was to evaluate the influence of obesity on histopathological changes of the graft during long-term follow-up.

Ischemic-Type Biliary Lesions After Liver Transplant: Factors Causing Early-Onset Versus Late-Onset Disease.

Objectives: Biliary complications such as an ischemic-type biliary lesion can increase morbidity and mortality after liver transplant. Former studies have investigated several risk factors, but the underlying pathomechanism remains unclear. The focus of this study was to investigate factors causing early-onset (< 12 mo after liver transplant) versus late-onset ischemic-type biliary lesions (> 12 mo after liver transplant).
