Safe Transition from Open to Total Minimally Invasive Esophagectomy for Cancer Utilizing Process Management Methodology.

The global shift from open esophagectomy (OE) to minimally invasive esophagectomy (MIE) for treating esophageal cancer is well-established. Recent data indicate that transitioning from hybrid minimally invasive esophagectomy (hMIE) to total minimally invasive esophagectomy (tMIE) can be challenging due to concerns about higher leakage rates and lower lymph node counts, especially at the beginning of the learning curve. This study aimed to demonstrate that a safe transition from OE to tMIE for cancer is possible using process management methodology.

Preparation and modeling of three-layered PCL/PLGA/PCL fibrous scaffolds for prolonged drug release.

The authors present the preparation procedure and a computational model of a three-layered fibrous scaffold for prolonged drug release. The scaffold, produced by emulsion/sequential electrospinning, consists of a poly(D,L-lactic-co-glycolic acid) (PLGA) fiber layer sandwiched between two poly(ε-caprolactone) (PCL) layers. Experimental results of drug release rates from the scaffold are compared with the results of the recently introduced computational finite element (FE) models for diffusive drug release from nanofibers to the three-dimensional (3D) surrounding medium.

Laparoscopic Management of Initially Unrecognized Splenic Hydatid Cysts: A Case Report and Review of the Literature.

We present a case report that demonstrates diagnostic and intraoperative challenges in the laparoscopic management of initially unrecognized splenic hydatid disease. A male patient, aged 44, was admitted to our department with a big unilocular splenic cyst, radiologically (ultrasonography, computed tomography) characterized as a simple cyst. Serological tests for anti-Echonococcus antibody were negative, and chests X-ray findings were unremarkable, so laparoscopic cyst fenestration with omentoplasty was planned.

Primary inflammatory myofibroblastic tumor of the stomach in an adult woman: a case report and review of the literature.

Inflammatory myofibroblastic tumor has been defined as a histologically distinctive lesion with uncertain behaviour. The term inflammatory myofibroblastic tumor more commonly referred to as "pseudostumor ", denotes a pseudosarcomatous inflammatory lesion that contains spindle cells, myofibroblasts, plasma cells, lymphocytes and histiocytes. It exhibits a variable biological behavior that ranges from frequently benign lesions to more aggressive variants.

PFA-100 test in the detection of platelet dysfunction and monitoring DDAVP in a patient with liver cirrhosis undergoing inguinal hernia repair.

Introduction: Hemostatic abnormalities in liver cirrhosis are complex and multifactorial and may predispose to prolonged hemorrhage following invasive procedures. Due to increased perioperative bleeding risks, patients with cirrhosis should undergo elective surgery after making medical preparations. It has been shown that 1-deamino-8-D-arginine vasopressin (DDAVP), desmopressin, can be used as a safe and effective remedy in preventing and treating bleeding in cirrhotics.

[Carcinoid syndrome in neuroendocrine tumors--not easy to recognize].

Neuroendocrine tumors (NET) are solid potentially malignant tumors originated from the diffuse neuroendocrine system. They could origin in many organs, with highest prevalence in lungs, small intestine and rectum. Characteristics of NET are slow growth, non-specific clinical presentation causing diagnostic problems.

[Neuroendocrine tumors of gastrointestinal tract: the paradigm that lasts].

Historically, the tumors that were morphologically different and clinically less agressive than the more common gastrointestinal adenocarcinomas were clasified under carcinoid tumors. However, the development of molecular biology tehniques revealed the heterogeneity of these tumors on cellular and subcellular level and ther different biological behaviour. Neuroendocrine tumors of gastrointestinal tract originated from neuroendocrine cells scaterred across the gastrointestinal mucosa.

Magnetic resonance imaging features of multiple duodenal lipomas: a rare cause of intestinal obstruction.

A 65-year-old man was evaluated because of vomiting and epigastric pain. The patient underwent upper gastrointestinal endoscopy and endoscopic ultrasound examination and was found to have multiple polypoid lesions in the D1 and D2 portions of the duodenum, causing almost complete obstruction of the duodenal lumen. The lesions were hyperintense on T1-weighted and intermediately intense on T2-weighted images, with a drop in signal on T1- and T2-weighted fat-suppressed images, consistent with a diagnosis of duodenal lipomas.
