Background: Over the past decade, facial aesthetics has gained popularity, with a notable increase in upper-face lift procedures. Despite the popularity of brows and forehead lifts, the optimal fixation technique remains controversial. Common methods involve suturing of the temporal fascia or using monocortical miniscrews anchored to the frontal bone.

Importance: Postoperative pancreatic fistulas (POPF) are the biggest contributor to surgical morbidity and mortality after pancreatoduodenectomy. The impact of POPF could be influenced by the surgical approach.

Objective: To assess the clinical impact of POPF in patients undergoing minimally invasive pancreatoduodenectomy (MIPD) and open pancreatoduodenectomy (OPD).

Background: Pancreatoduodenectomy in elderly patients may be associated with increased postoperative mortality, but studies in minimally invasive pancreatoduodenectomy (MIPD) are scarce.

Methods: International multicenter retrospective study including patients aged >60 years undergoing MIPD (robot-assisted and laparoscopic) and open pancreatoduodenectomy (OPD), were categorized by age: 60-69, 70-79, and 80+ years. In each category, propensity score matching (PSM) was performed (1:1 ratio) between MIPD and OPD.

Objectives: The aim of this study was to evaluate the predictive value of the first postoperative day (POD1) drain fluid amylase in predicting pancreatic fistula formation following pancreaticoduodenectomy (PD).

Material And Methods: One-hundred and eighty-five prospective patients undergoing PD between April 2014 and April 2018 were studied retrospectively. Cut-off point to predict the development of POPF was determined by median values for drain fluid amylase of 1883 U/L.

Article Synopsis
  • The rise in midface and temporal lifting procedures is driven by social media trends and younger patients' desire for beautification rather than traditional rejuvenation, favoring scarless techniques.
  • A retrospective study of 184 patients utilizing a dual-plane lifting method showed significant improvements in facial volume distribution post-surgery with manageable complications.
  • This dual-plane approach minimizes visible scars and enhances facial aesthetics, making it a viable option for those seeking both beauty and rejuvenation, despite some risks like infection.

Objectives: The aim of this study was to compare the results of the evaluation of HPB-specific pathologists and general pathologists on the specimens of patients who underwent pancreaticoduodenectomy by the same surgical team.

Material And Methods: The pathological results of 159 patients who underwent pancreaticoduodenectomy (PD) in the periampullary region was retrospectively examined. Histopathological evaluation results of HPB-specific pathologist (S group) and other pathologists (NS group) were compared.

Objective: To assess postoperative 90-day outcomes after minimally invasive (laparoscopic/robot-assisted) total pancreatectomy (MITP) in selected patients versus open total pancreatectomy (OTP) among European centers.

Background: Minimally invasive pancreatic surgery is becoming increasingly popular but data on MITP are scarce and multicenter studies comparing outcomes versus OTP are lacking. It therefore remains unclear if MITP is a valid alternative.

Sensory Substitution Devices (SSDs) convey visual information through audition or touch, targeting blind and visually impaired individuals. One bottleneck towards adopting SSDs in everyday life by blind users, is the constant dependency on sighted instructors throughout the learning process. Here, we present a proof-of-concept for the efficacy of an online self-training program developed for learning the basics of the EyeMusic visual-to-auditory SSD tested on sighted blindfolded participants.

Objectives: This study aimed to analyze the correlations between European Neuroendocrine Tumor Society (ENEST), Tumor Node Metastasis (TNM) staging systems and pre-operative neutrophil/lymphocyte (NLR) and platelet/lymphocyte ratios (PLR) in patients with pancreatic neuroendocrine tumor (PNET).

Material And Methods: Forty-four patients with diagnosed PNET were analyzed retrospectively. Accordingly, the patients' blood and clinicopathological parameters were analyzed.

Purpose:   Adiponectin is a protein stemming from adipose tissue and having strong anti-inflammatory properties. We aimed to assess the damage diminishing effects of recombinant adiponectin  (rAD) through NF-kB in the experimental acute pancreatitis  (AP) model.

Materials And Methods:   Acute pancreatitis was created by applying 50 µg/kg dose of intraperitoneal cerulean.

Laparoscopic pancreatoduodenectomy is a challenging surgical procedure. Presence of aberrant hepatic artery arising from the superior mesenteric artery increases the complexity througout dissection. Herein we propose some important points and tricks that help surgeon avoid an inadverdent injury to aberrant hepatic artery during laparoscopic pancreatoduodenectomy.

BACKGROUND The aim of this study was to compare the clinical outcome in patients with pancreatic ductal adenocarcinoma who underwent frozen section and paraffin section histology of the surgical resection margins during pancreaticoduodenectomy. MATERIAL AND METHODS Frozen section and routine paraffin section histopathology were performed using the following categories: R0 (no tumor cells at the surgical resection margin), R1 (tumor cells at, or within 1 mm, of the surgical resection margin), and R2 (tumor seen macroscopically at the surgical resection margin). R1 and R2 patients underwent additional resection to achieve R0.

Objective: To assess short-term outcomes after minimally invasive (laparoscopic, robot-assisted, and hybrid) pancreatoduodenectomy (MIPD) versus open pancreatoduodenectomy (OPD) among European centers.

Background: Current evidence on MIPD is based on national registries or single expert centers. International, matched studies comparing outcomes for MIPD and OPD are lacking.

Objective: There is an increase in the incidence of cancer, and consequently in mortality rates, both in the world and in Turkey. The increase in the incidence and mortality rate of cancer are more prominent in our country as well as in other developing countries. The aim of this workshop was to determine the current status on prevention, screening, early diagnosis and treatment of cancer in our country, to identify related shortcomings, specify solutions and to share these with health system operators, and to aid in implementation of these systems.

Objectives: Resistin, a hormone secreted from adipocytes and considered to be a likely cause of insulin resistance, has recently been accepted as a proinflammatory cytokine. This study aimed to determine the correlation between resistin levels in patients with intra-abdominal sepsis and mortality.

Methods: Of 45 patients with intra-abdominal sepsis, a total of 35 adult patients were included in the study.

Background/aims: Peroxisome proliferators-activated receptor alpha activation modulates cholesterol metabolism and suppresses bile acid synthesis. The trefoil factor family comprises mucin-associated proteins that increase the viscosity of mucins and help protect epithelial linings from insults. We evaluated the effect of short-term administration of fenofibrate, a peroxisome proliferators activated receptor alpha agonist, on trefoil factor family-3 expression, degree of apoptosis, generation of free radicals, and levels of proinflammatory cytokines in the liver tissue of bile duct-ligated rats.

Orofacial clefts are congenital defects that vary widely in type and severity, and can occur in isolation or in association with a variety of other defects. Herein, we describe a consanguineous family afflicted with a unique form of orofacial clefting manifesting as a facial midline defect that also involves mandibular and maxillary structures. All four affected sibs had median clefts of the upper and lower lips, tooth misalignment, and poor oral hygiene.
