Robotics in Pancreatic Surgery
Yakup Kulu, Thilo Hackert
REVIEW, June 2020
Article DOI: 10.21614/sgo-25-3-108
Read article Robotic procedures have been implemented and become an important development in pancreatic surgery with an increasing acceptance worldwide.
Nearly all types of pancreatic surgery have been performed robotically and especially standardized resections such as distal pancreatectomy and partial pancreatico-duodenectomy have gained importance despite a potentially long learning curve and increased procedure costs.

The present review outlines the past and current developments in robotic pancreatic surgery and summarizes the available literature and evidence on the respective ....[more]
Portal Pressure Impact on Clinical Outcome after Major Hepatectomy: A Systematic Review and Meta-Analysis

REVIEW, June 2020
Article DOI: 10.21614/sgo-25-3-113
Read article Aim of the study: To systematically review the evidence regarding the association between portal venous pressure (PVP) after hepatectomy and posthepatectomy liver failure (PLHF) or other postsurgical outcomes.

Materials and methods: We searched PubMed, Scopus and Web of Science for studies assessing post-hepatectomy PVP (or its variation) and reporting its association with PHLF or other postsurgical outcomes. We performed a random-effects meta-analysis for the association between development of PHLF and post-hepatectomy PVP and its variation.

REVIEW, June 2020
Article DOI: 10.21614/sgo-25-3-121
Read article Introduction: There is a significant association between psychiatric diseases and esophageal disorders. The upper esophageal sphincter (UES) function may be affected by psychiatric diseases. This study aims to evaluate the correlation between psychiatric symptoms (anxiety and depression) and UES pressure.

Methods: We retrospectively reviewed data from 200 adult patients (median age 41 (34-53) years; 47% males). All patients underwent high-resolution esophageal manometry and ambulatory pH monitoring. UES basal pressure (UESP) was measured at the beginning of th....[more]

Article DOI: 10.21614/sgo-25-3-125
Read article Background: Liver transection consists of two elements, crushing of the liver parenchyma and sealing of the remaining tissue. We aimed to investigate the influence of the technique used for crushing liver parenchyma on clinical outcomes in patients with hepatocellular carcinoma (HCC).

Methods: We investigated data from 65 consecutive patients who underwent open hepatectomy for HCC between January 2012 and December 2018. Patients were divided into two groups based on the technique used for crushing liver parenchyma, defined as the direct LigaSure crushing group (....[more]
Factors Impacting Survival Outcomes after Curative Resection for Primary Duodenal Adenocarcinoma
Masayuki Urabe, Junichi Shindoh, Yuta Kobayashi, Satoshi Okubo, Shusuke Haruta, Masaki Ueno, Masaji Hashimoto
Article DOI: 10.21614/sgo-25-3-132
Read article Background: Primary duodenal adenocarcinoma (PDA) is a rare gastrointestinal tumor and factors predicting survival outcomes after curative resection have yet to be fully elucidated.

Methods: Applying the Cox proportional hazard model, we retrospectively evaluated associations between overall relapse-free survivals (OS RFS) and 18 clinicopathological factors in 33 patients who had undergone R0 resection for PDA.

Results: Univariate analysis revealed worsening RFS to be significantly related to pancreatic invasion, multiple nodal metastases, and the....[more]
Vertical Bipartition of the Right Anterior Section by Extraglissonian Approach
Ionel Câmpeanu, Irinel Popescu, Liviu Mosoia, Florin Botea
Surgical Technique, June 2020
Article DOI: 10.21614/sgo-25-3-140
Read article By positioning the right anterior section (RAS) in the right hemiliver, the classic right hepatectomy (RH), sectionectomy or segmentectomy concept is not always appropriate for this section.
Besides the classic Couinaud cranio-caudal division of RAS, there is also a vertical bipartition of RAS in two subsections (ventral and dorsal) based both on the portal systematization of the tertiary Glissonian pedicles spatial distribution and on the supra hepatic Couinaud systematization.

This study discusses the anatomical basis of the extra-Glissonian resections, as well as v....[more]
Solitary Fibrous Tumor of the Omentum: Presentation of a Case and Literature Review
Carlo Biddau, Lorenzo Cereser, Panagiotis Paliogiannis, Giovanni Terrosu, Alessandro Uzzau
Images in Clinical Medicine, June 2020
Article DOI: 10.21614/sgo-25-2-155
Read article Solitary fibrous tumor (SFT) and hemangiopericytoma (HPC) were considered, since their firsts description in the literature, as separate entities. The World Health Organization (WHO) classification of soft tissue tumors in 2013 declared the term HPC obsolete, and considered these lesions as features of the extrapleural SFT category. Herein we present a rare case of SFT originating from the great omentum.
A 68 years old woman was admitted to our hospital with acute abdominal pain. Computed tomography revealed a 142 x 102 x 100 mm solid mass located in the pelvis, that simulated ....[more]
