Microscopic Positive Margins in Gastric Adenocarcinoma Following Oncological Resection: Prognostic Factors and Long-Term Survival.

Background: In the context of gastric cancer, surgical resection stands as the sole curative treatment. Central to influencing overall survival are the resection margins. This research aims to identify the factors influential in determining microscopically positive resection margins (R1) and to evaluate overall survival.

A novel step-by-step training program for transanal endoscopic surgery.

Background: The objective of our study is to develop an effective training platform for transanal endoscopic surgery and to validate a step-by-step training program for learning the basic skills necessary for this approach.

Methods: We have designed a two-part study: an experimental study (with the aim to design the training platform and the training exercises - on synthetic and biological material) and a prospective analytical study, in order to validate the training program by enrolling as participants general surgery residents and specialists, without previous experience in transanal endoscopic interventions. The performance of the participants was assessed based on the time of completion, as well as the quality of the execution.

Trends in Minimally Invasive Approaches for Liver Resections-A Systematic Review.

Background: SILS (single incision laparoscopic surgery) and NOTES (natural orifice transluminal endoscopic surgery) are considered breakthroughs in minimally invasive surgery, the first consisting in the surgeon working via a single entrance site and the second via a natural orifice (e.g., oral cavity).

Duodenopancreatectomy for PDAC Associated with MALS: A Case Report.

Pancreatic ductal adenocarcinoma (PDAC) is an aggressive form of pancreatic malignancy which occurs in over 90% of such cases. Pancreaticoduodenectomy (PD) is used with a curative purpose for localized PDAC. Case presentation: A 68-year-old woman presented to our service through a transfer from another service, to be investigated and treated for a head of the pancreas tumor in a tertiary referral hospital.

Stapled Hemorrhoidopexy: Technique and Long Term Results.

Stapled hemorrhoidopexy (Longo operation) is a infrequent technique in our area. A different concept from hemorrhoidectomy, a proportionally important raise in cost and a special training may have contributed to it. We report our long-term results with the standard technique.

Greyscale and contrast enhanced ultrasonography for characterization of gastric malignant tumors.

Aims: To evaluate the utility of grey scale ultrasonography (US) and contrast enhanced ultrasonography (CEUS) for characterization of malignant gastric tumors.

Material And Methods: The study was conducted prospectively and it included a number of 30 patients with malignant gastric tumors diagnosed through upper tract endoscopy and biopsy: 25 adenocarcinomas, 3 lymphomas, and 2 stromal tumors. All the patients were examined by US, followed immediately by CEUS, using both oral and intravenous contrast agents.

Ethical considerations in bariatric surgery in a developing country.

Background And Aims: Obesity is the fastest growing health problem worldwide. Ethical issues linked to obesity are numerous and still under debate even in countries with a long history in obesity treatment.

Methods: From 2007 to 2015 we performed several types of bariatric surgical approaches on 250 patients with an average body mass index (BMI) of 42.

Therapeutic Challenges for Symptomatic Portal Cavernoma Cholangiopathy.

Although transjugular intrahepatic portosystemic shunts are most frequently used for the management of portal hypertension, the surgical approach is preferred for symptomatic portal cavernoma cholangiopathy. We present the case of a 25-year old female patient with a portal cavernoma secondary to catheterization of the umbilical vein at birth. She had had two episodes of esophageal variceal bleeding, successfully treated by endoscopic banding.
