Determination of Soil Contamination at the Wildland-Urban Interface after the 2021 Marshall Fire in Colorado, USA.

Wildfires at the wildland-urban interface (WUI) are increasingly common. The impacts of such events are likely distinct from those that occur strictly in wildland areas, as we would expect an elevated likelihood of soil contamination due to the combustion of anthropogenic materials. We evaluated the impacts of a wildfire at the WUI on soil contamination, sampling soils from residential and nonresidential areas located inside and outside the perimeter of the 2021 Marshall Fire in Colorado, USA.

The Montecristo mining district, northern Chile: the relationship between vein-like magnetite-(apatite) and iron oxide-copper-gold deposits.

Unlabelled: The Montecristo district, northern Chile, is one of the few places worldwide where there is a direct relationship between magnetite-(apatite) (MtAp) mineralization and iron oxide-copper-gold (IOCG) mineralization. The MtAp mineralization includes Ti-poor magnetite, fluorapatite, and actinolite and is crosscut and partially replaced by a younger IOCG mineralization that includes a second generation of actinolite and magnetite with quartz, chalcopyrite, pyrite, and molybdenite. The MtAp stage at Montecristo is interpreted as the crystallized iron-rich melts that used the pre-existing structures of the Atacama Fault System as conduits.

Use of extracorporeal membrane oxygenation in non-elective major thoracic surgery for infectious lung abscess.

Objectives: Extracorporeal membrane oxygenation (ECMO) support for elective cardiothoracic surgery is well established. In contrast, there are not much data regarding the usefulness and outcome of ECMO in non-elective major lung resections for infectious lung abscess.

Methods: All patients undergoing non-elective major lung surgery for infectious lung abscess at 5 centres in Germany, UK and Spain were enrolled in a prospective database.

Introduction: Hybrid laparoscopic techniques have been proposed as a good transition from open to complete minimally invasive approach especially in complex surgical procedures. This meta-analysis aimed to compare the outcomes of hybrid laparoscopic pancreatoduodenectomy versus open pancreatoduodenectomy.

Methods: A systematic literature research was performed according to PRISMA guidelines.

Intraoperative conversion and complications in robotic assisted primary and redo gastric bypass surgery.

The rise of robotic assisted surgery in the treatment of morbidly obese patients has enlarged the armamentarium for surgeons involved in bariatric surgery. This in particular is of great advantage not only in primary cases, but also in patients undergoing revisional procedures following preceding upper GI surgery. In the following, our experience with intraoperative conversions and complications in revisional robotic surgery using the Da Vinci robotic system will be reported and compared to primary robotic bypass surgery and the literature.

Minimally Invasive Conversion of a Gastric Bypass into Sleeve Gastrectomy for Postprandial Hyperinsulinemic Hypoglycemia.

The treatment of postprandial hyperinsulinemic hypoglycemia following gastric bypass surgery for obesity can be challenging despite dietetic and medical treatment and eventually surgical treatment remains the exclusive treatment to resolve the problem for the patient. In the following, the experience with a conversion surgery from a complicated Roux-en-Y gastric bypass to sleeve gastrectomy using the Da Vinci robotic system will be reported.

Hybrid robotic versus hybrid laparoscopic Ivor Lewis oesophagectomy: a case-matched analysis.

Objectives: Robotic-assisted oesophagectomy for cancer has been increasingly employed worldwide; however, the benefits of this technique compared to conventional minimally invasive oesophagectomy are unclear. Since 2016, hybrid robotic minimally invasive oesophagectomy (R-HMIE) has increasingly replaced hybrid laparoscopic minimally invasive oesophagectomy (HMIE) as the standard of care in our institution. The aim of this study was to compare these procedures.

[Leiomyoma of the esophagus : A further indication for robotic surgery?].

Background: Leiomyomas of the esophagus are rare tumors but the most common benign lesion of the esophagus originating from smooth muscle cells. The symptoms are mainly determined by the size of the tumor and are caused by dysphagia and/or retrosternal pain. The majority of patients are however asymptomatic.

Prognostic Value of Chest-Tube Amylase Versus C-Reactive Protein as Screening Tool for Detection of Early Anastomotic Leaks After Ivor Lewis Esophagectomy.

Introduction: Intrathoracic anastomotic leaks after esophagectomy are a significant cause of morbidity and death. Early detection and timely management are crucial. This study evaluates the effectiveness of daily drain amylase levels in detecting early leaks after esophagectomy compared with C-reactive protein (CRP).

Traumatic oesophageal perforation: a successful management based on the Pittsburgh Perforation Severity Score.

Oesophageal perforation is a severe life-threatening clinical condition with high mortality and morbidity needing rapid interdisciplinary approach to be effectively managed. Recently, on the basis of multicentric retrospective data, we proposed a decision tree for the treatment of oesophageal perforations based on the Pittsburgh Perforation Severity Score (PSS). We now report the first case of a traumatic oesophageal perforation, which was successfully treated according to the application of the PSS decision tree.

Gastric carcinoma after sleeve gastrectomy for obesity.

Obesity is associated with an increased risk of cancer development in the upper gastrointestinal tract. We present the case of a female patient with gastric carcinoma after sleeve gastrectomy. Before bariatric surgery, one rationale for performing routine endoscopy is to detect clinically relevant conditions with the potential to change the surgical procedure.

Predictors of Outcome in Modern Surgery for Lung Abscess.

 Surgery for lung abscess is a challenging task. Timing and indications for surgery are not well established. Identification of predictors of outcome could help to clarify the role of surgery.

[Laparoscopic Heller myotomy after failed POEM and multiple balloon dilatations : Better late than never].

Background: Despite the lack of long-term results, peroral endoscopic myotomy (POEM) has been increasingly propagated as a feasible alternative to pneumatic balloon dilatation (BD) and laparoscopic Heller myotomy (LHM) in patients with achalasia. After a long-term follow-up, a large percentage of patients reported recurrence of dysphagia. It is unclear which kind of procedure (redo POEM or LHM) should be utilized in these patients with failed POEM.

Spotlight on esophageal perforation: A multinational study using the Pittsburgh esophageal perforation severity scoring system.

Objective: The Pittsburgh group has suggested a perforation severity score (PSS) for better decision making in the management of esophageal perforation. Our study aim was to determine whether the PSS can be used to stratify patients with esophageal perforation into distinct subgroups with differential outcomes in an independent study population.

Methods: In a retrospective study cases of esophageal perforation were collected (study-period, 1990-2014).

Adenocarcinoma of the Distal Esophagus in a Patient With a Magnetic Sphincter Augmentation Device: First of Many to Come?

Recently an alternative treatment option utilizing a laparoscopically placed magnetic sphincter device has been introduced for gastroesophageal reflux disease patients who are hesitant to undergo Nissen-fundoplication. Based on previous experience with similar devices, concerns have been raised about migration, and in case of a subsequently developing esophageal cancer, technical challenges during the endoscopic or surgical treatment caused by the foreign body reaction around the abdominal esophagus. In this article, we report of the first case of esophagectomy for cancer in a patient with a previously implanted magnetic sphincter augmentation device.

Predictors of Lymph Node Metastasis in Surgically Resected T1 Esophageal Cancer.

Background: The application of endoscopic therapies for early cancers of the esophagus is limited by the possible presence of regional lymph node metastases. Our objective was to determine the prevalence and predictors of lymph node metastases in patients with pT1 carcinoma of the esophagus and the gastric cardia.

Methods: The National Cancer Institute's Surveillance Epidemiology and End Results Database (2004 to 2010) was used to identify all patients with pT1 carcinomas who underwent primary surgical resection for squamous cell carcinoma (SCC) or adenocarcinoma (EAC) of the esophagus and of the esophagogastric junction (AEG).

Emergency oesophagectomy for oesophageal perforation after chemoradiotherapy for oesophageal cancer.

Introduction: Oesophageal perforation following chemoradiotherapy for oesophageal cancer is a devastating condition but there have been no studies investigating the role of emergency oesophagectomy for this life threatening situation.

Methods: This retrospective study comprised all cases of emergency oesophagectomy for oesophageal perforation after chemoradiotherapy for oesophageal carcinoma at a major centre for oesophageal surgery in Germany between 2004 and 2013.

Results: A total of 13 patients (mean age: 58.

One decade of experience with endoscopic stenting for intrathoracic anastomotic leakage after esophagectomy: brilliant breakthrough or flash in the pan?

Management of intrathoracic anastomotic leakage after esophagectomy by means of endoscopic stent insertion has gained wide acceptance as an alternative to surgical reintervention. Between January 2004 and March 2013 all patients who underwent esophagectomy at a German high-volume center for esophageal surgery were included in this retrospective study. The study comprises 356 patients.
