Background: Despite the improvement in therapies, pancreatic cancer represents one of the most cancer-related deaths. In our hypothesis, we propose that Hyperthermic Intraperitoneal Chemotherapy with gemcitabine after pancreatic cytoreductive surgery could reduce tumor progression by reducing residual neoplastic volume and residual pancreatic cancer stem cells.

Materials And Methods: A randomized trial involving 42 patients.

Multidisciplinary strategies have transformed the management of advanced ovarian cancer. We aimed to evaluate the effectiveness of paclitaxel in hyperthermic intraperitoneal chemotherapy (HIPEC) following surgical cytoreduction for ovarian peritoneal metastases in a randomized phase III trial conducted between August 2012 and December 2019. Seventy-six patients were randomized to either the HIPEC or no HIPEC group.

Background: Pancreatic ductal adenocarcinoma (PDAC) is one of the main causes of cancer mortality in the world. A characteristic feature of this cancer is that a large part of the tumor volume is composed of a stroma with different cells and factors. Among these, we can highlight the cytokines, which perform their function through binding to their receptors.

Background: Hyperthermic intraperitoneal chemotherapy (HIPEC) with gemcitabine, after cytoreductive surgery, may reduce the tumor progression of pancreatic cancer through the reduction of the neoplastic volume and the subpopulation of residual pancreatic cancer stem cells, improving the survival of patients with pancreatic cancer and decreasing the recurrence of the disease.

Methods: A pilot study is performed with the first ten patients in the experimental group. A randomized study (phase II-III clinical trial) that requires a population of 42 patients, with 21 patients in each group.

Introduction: Duplicity of the common bile duct is an unusual congenital disorder.

Case Report: A 80-year-old woman with duplication of the common bile duct with retrograde endoscopic cholangiopancreatography (ERCP) who did not resolve the symptoms.

Discussion: Our case is a variant of type IV to the classification of duplicity of the common bile duct.

Introduction: Duplicity of the common bile duct (BCBD) is an unusual congenital disorder.

Case Report: A 80-year-old woman with duplication of the common bile duct with retrograde endoscopic cholangiopancreatography (ERCP) who did not resolve the symptoms.

Discussion: Our case is a variant of type IV to the classification of DCBC.

Introduction: Hyperthermic intraperitoneal chemotherapy (HIPEC) is an effective treatment for peritoneal carcinomatosis (PC). Laparoscopic surgery is performed in the treatment of colorectal and appendiceal cancer, and PC from diverse origin in selected patients. HIPEC management by laparoscopic approach after cytoreductive surgery (CRS) completed locoregional treatment of PC, and may be feasible and safe after appropriate patient selection.

Purpose: To determine the effectiveness of thermography to control the distribution of abdominal temperature in the development of a closed chemohyperthermia model.

Materials And Methods: For thermographic analysis, we divided the abdominopelvic cavity into nine regions according to a modification of carcinomatosis peritoneal index. A difference of 2.

Objective: The origin of pancreatic cancer has been identified as a population of malignant pancreatic stem cells CD133+ CXCR4+ immunophenotype. These cells have high capacity for early locoregional invasion, being responsible for early recurrence and high mortality rates of pancreatic cancer. We propose a study for decreasing tumor progression of pancreatic cancer by reducing the volume and neoplastic subpopulation of pancreatic cancer stem cells CD133+ CXCR4+.

Background This paper reports a study of 21 patients with peritoneal carcinomatosis from ovarian cancer who underwent cytoreductive surgery and HIPEC by means of PRS-1.0 Combat®, a new model for closed abdomen HIPEC aimed at improving fluid distribution with assistance from a CO2 recirculation system. This new technology has been previously shown to be successful in an experimental study (pig model) performed by our group, and has been approved for use in our hospital.

Unlabelled: Carcinosarcoma is a malignant neoplasm characterized for intermingled epithelial and mesenchymal components.

Case Report: A preoperative suspected diagnosis will allow a radical therapy avoiding a very bad prognosis. We report on a male patient who was operated in our Service with diagnosis of synchronous carcinosarcoma of gallbladder and extrahepatic bile duct and a review of the Medical Literature.

Background: Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy is the best operative treatment currently available for patients with peritoneal carcinomatosis of ovarian origin. The open abdomen technique is the classic technique for hyperthermic intraperitoneal chemotherapy. We developed a closed abdomen model that improves temperature control and increases exposure of peritoneal surfaces to the drug by recirculating the perfusate.

Objective: To present physiologic intraoperative data and immediate postoperative outcomes of patients diagnosed with epithelial ovarian cancer submitted to cytoreductive surgery and hyperthermic peritoneal intraoperative chemotherapy (HIPEC) with a closed-circuit, turbulent-flow system.

Materials And Methods: A closed-circuit system with CO2 turbulent flow was used for paclitaxel HIPEC during 60 min for patients diagnosed with stage II or higher and recurrent epithelial ovarian cancer. Perioperative hemodynamic and metabolic statuses were followed, as well as physiologic recovery during the first 12 postoperative hours.

Introduction: Nesidioblastosis is a rare disease caused by hyperplasia of pancreatic islets, developing a state of hypoglycemia due to an increase in the insulin production. It is the leading cause of hyperinsulinic hypoglycemia in childhood, whereas in adults it only represents the 0.5-5% of cases.

Introduction: In 2008, colorectal cancer represented the third most commonly diagnosed tumor in Spain, and the second tumor with more deaths. Despite the new potential biomarkers in colorectal cancer, there are many challenges that need to be overcome, resulting in a need for the standardization of its determinations.

Discussion: The continuous advance in tumor disease knowledge makes this review a summary of the current accepted, recommended and studied tumor markers for the diagnosis and monitoring of colorectal cancer, such as fecal markers, tissue markers and serological markers, and various prognostic markers on which there are different lines of treatment in colorectal cancer.

Introduction: Up to 45% anatomical variations are found in hepatic arterial system. Identifying these anatomical anomalies before or during surgery would prevent additional morbidity in performing a duodenopancreatectomy. They are routinely identified before surgery using CT imaging, but on certain occasions they are not reported and are only discovered during the surgical operation.

Introduction: Angiogenesis and lymphangiogenesis are essential processes for the formation of blood and lymphatic vessels that allow tumour growth and spread. The binding of VEGF and VEGF-C factors with their receptors (VEGFR2, VEGFR3) in endothelial cells triggers signals that regulate these processes. We compared preoperative serum VEGF and VEGF-C levels with samples obtained after completion of surgery and adjuvant treatment in patients with gastric cancer.

Background: Diaphragmatic rupture can be missed during trauma diagnosis. Different pressures between the thorax and the abdomen allow the abdominal viscera to herniate into the chest cavity. Cardiorespiratory and abdominal symptoms may appear later due to passive compression and incarceration, respectively.

Background: Gliomatosis peritonei is the metastatic implantation of mature glial tissue within the peritoneal cavity of patients with ovarian teratomas. There is no clear guidance for how long these patients should be followed up.

Clinical Case: We report the follow-up imaging findings of a 33-year-old female with abdominal distension and abdominal pain and who was postoperatively diagnosed with immature ovarian teratoma with gliomatosis peritonei.

Background: pylephlebitis is a rare complication of intraabdominal infections. Clinical presentation can be varied; therefore, it is necessary to carry out imaging tests for diagnosis. The treatment of choice is wide-spectrum antibiotic therapy and surgery for the source of infection.

Introduction: Natural orifice endoscopic surgery is a new surgical procedure still in the development phase. The most natural entry for surgeons is to use an already existing scar, such as the navel. The recent introduction of trocars designed for this purpose has made it possible to put this into practice.
