Radical cytoreductive surgery and hyperthermic intraperitoneal chemotherapy in the treatment of peritoneal sarcomatosis: Results from a reference center and considerations based on current evidence.

Introduction: Peritoneal sarcomatosis is a rare disease, with multiple histological origins and poor overall prognosis. The option of radical cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) is controversial. The results of a surgical team experienced in these procedures are analyzed and discussed based on the available evidence.

2023 GEIS Guidelines for gastrointestinal stromal tumors.

Gastrointestinal stromal tumor (GIST) is the most common malignant neoplasm of mesenchymal origin. GIST spans a wide clinical spectrum that ranges from tumors with essentially no metastatic potential to malignant and life-threatening spread diseases. Gain-of-function mutations in KIT or PDGFRA receptor tyrosine kinases are the crucial drivers of most GISTs, responsible for tumor initiation and evolution throughout the entire course of the disease.

Avances en tumores del estroma gastrointestinal: ¿hacia dónde vamos?

Gastrointestinal Stromal Sarcomas (GIST) are mesenchymal neoplasms whose incidence accounts for 1-2% of digestive tumors, being located in the stomach (55-60%) and small intestine (30%). The advances in its knowledge and management succeeded in the last years have being spectacular. This review aims to summarize the most important of them for surgeons.

Simultaneous pancreas-kidney transplantation: Early complications and long-term outcomes - a single-center experience.

Introduction: This study aimed to assess the prevalence and severity of complications after simultaneous pancreas-kidney transplantation (SPKT) and to evaluate its influence on both grafts' long-term results.

Methods: This was an observational, retrospective study including 39 consecutive SPKT cases from 2000-2018. Complications were classified into kidney-related and pancreas-related.

Biomarkers of Early Liver Graft Damage in Circulatory Death and Brain Death Donors: A Propensity Score Matching Analysis.

Background: Donation after circulatory death (DCD) is related to a warm ischemia time and more complications compared with traditional donors (donation after brain death [DBD]).

Methods: This study included biopsy samples retrospectively collected from November 2014 to December 2018 to compare histologic and biological markers of DCD and DBD liver grafts. The analysis includes marker of early apoptosis (p21), senescence (telomerase reverse transcriptase [TERT]), cell damage (caspase-3 active), endothelial damage (vascular endothelial growth factor), stem cell (CD90), hypoxia (HIF1A), inflammatory activation (COX-2), and cross-organ allograft rejection (CD44).

[Giant lipomas or retroperitoneal liposarcomas? Controversies in their diagnosis and treatment].

Background: Retroperitoneal lipomas are extremely rare tumors that must be differentiated from well-differentiated liposarcomas (WD-LPS).

Objectives: To summarize the evidence about giant retroperitoneal lipomas or liposarcomas; and to elaborate recommendations for their management.

Data Sources: A systematic literature search from January 1985 to December 2019 and a review of our own cases was performed.

Update in pelvic and retroperitoneal sarcoma management: The role of compartment surgery.

Surgery for retroperitoneal sarcomas should be "en bloc" compartmental, which involves resection of unaffected organs. Its upfront use is key, providing a high percentage of resections with negative margins, resulting in a better local control and increased survival in many patients. Preservation of organs should be done in an individualized manner, especially in the pelvic location, and adapted to the histological aggressiveness of the tumor.

Controlled donation after circulatory death up to 80 years for liver transplantation: Pushing the limit again.

Our main objective was to compare liver transplant (LT) results between donation after circulatory death (DCD) and donation after brainstem death (DBD) in our hospital and to analyze, within the DCD group, the influence of age on the results obtained with DCD donors aged >70 years and up to 80 years. All DCD-LTs performed were analyzed prospectively. The results of the DCD group were compared with those of a control group who received a DBD-LT immediately after each DCD-LT.

An ulcerated gastric ulcer and pseudotumour with pancreatic affectation associated with immunoglobulin G4-related disease: a case report and literature review.

We report the case of a 67 year old male who presented with a nine year history of a gastric ulcer with symptoms of hematemesis and melena. Histological analysis identified fibrotic lesions and the accumulation of immunoglobulin G4-positive plasma cells with no evidence of malignancy. The lesion extended into the pancreas, where histological lesions and gastric lesions were also observed.

[Additional primary malignancies in patients with gastrointestinal stromal tumors. Proposal for a new classification].

Additional primary malignancies in patients with gastrointestinal stromal tumor (GIST) is not only common but of growing interest in the scientific literature. This association is of great importance in terms of clinical challenge, diagnosis and therapy as well as for the prognosis impact it implies. In the published series there is a tendency to group these patients to determine the specific and distinguishable characteristics of GIST associated with other malignancies.

The assessment of the Newborn Hearing Screening Program in the Region of Murcia from 2004 to 2012.

Objectives: Newborn (NB) auditory deficit has a prevalence of 1-2% in the world. Since the 1990s different screening programs have been put into practice. The Newborn Hearing Screening Program has been in operation since 2002 in our hospital (HCUVA) in Murcia (Spain) and two years later it was introduced into the whole of the Autonomous Community of the Region of Murcia as part of universal healthcare.

[Primary, non-metastatic gastrointestinal stromal tumour surgery: results of the GRISK study].

Introduction And Objectives: Radical surgery is the standard treatment for localised gastrointestinal stromal tumours (GIST). A series of primary GIST, their treatment and pre-established risk of recurrence after their follow-up is evaluated.

Material And Methods: A retrospective, descriptive and multicentre study was conducted on primary, non-metastatic GIST operated on between June 2007 and December 2008.

[Delayed right hepatic artery haemorrhage after iatrogenic gallbladder by laparoscopic cholecystectomy that required a liver transplant due to acute liver failure: clinical case and review of the literature].

Introduction: Right hepatic artery (RHA) injury after laparoscopic cholecystectomy (LC) may go unnoticed clinically, but can sometimes cause necrosis of the right lobe. Exceptionally, when the necrosis spreads to segment IV, fulminant liver failure (FLF) may occur, and an urgent liver transplantation (LT) may be required.

Patients And Method: We provide a review of the literature on patients with indication for an LT due to vascular damage caused by bile duct injury following LC.

[Unilocular macrocystic serous cystoadenoma of the pancreas].

The differential diagnosis between macrocystic serous cystoadenoma and mucinous cystoadenoma is very difficult but is highly important due to the latter's potential for malignant transformation. We present a case of unilocular macrocystic serous cystoadenoma. Due to the impossibility of obtaining an accurate preoperative diagnosis, all macrocystic unilocular lesions, in an appropriate clinical context, must be resected.
