Evaluation of near-Infrared fluorescence-conjugated peptides for visualization of human epidermal receptor 2-overexpressed gastric cancer.
2021
338 Background: HER2 is highly overexpressed in many kinds of cancers with a poor prognosis. Recently, near-infrared (NIR) fluorescence-based imaging is a growing field for both pre-clinical and clinical application. In this study, we aimed to synthesize Human Epidermal Receptor2 (HER2)-specific near-infrared (NIR) fluorescence probes and evaluate their applicability in cancer-specific image-guided surgeries using an animal model. Methods: An NIR dye emitting light of 800 nm (IRDye800CW, Li-COR, USA) was conjugated to trastuzumab and HER2-specific affibody using click mechanism. HER2 affinity was assessed by the surface plasmon resonance technique. HER2 positive/negative gastric cancer cel…
Uncommon Synchronous Association between Ovarian Carcinoma and Gastrointestinal Stromal Tumor: A Case Study and Literature Review
2013
Background The association of gastrointestinal stromal tumors (GIST) and other cancers is well known, but its synchronous occurrence with gynecological malignancies is very uncommon. Usually, the diagnosis is accidentally established. We describe a patient with GIST and concurrent ovarian cancer and discuss the clinical implications of this finding. Case report A 64-year-old woman with a prior diagnosis of ovarian cancer developed a second recurrence after having undergone two operations and adjuvant chemotherapy. While tumor debulking was performed, a small, nonsuspicious lesion was removed from the greater curvature of the stomach. Histology revealed a GIST. Conclusion The association of …
Morphometrische Untersuchungen an Darminterponaten nach totaler Gastrektomie
1982
Im Tierexperiment wurden nach totaler Gastrektomie die Bildung eines Ersatzmagens mit verschiedenen Darminterponaten sowie der Oesophago-Jejunostomie mit Roux-Y-Anastomose durchgefuhrt. Bei der Relaparotomie nach 3monatiger postoperativer Uberlebenszeit wurden die Interponate an ausgewahlten Stellen morphometrisch untersucht. Als deutlichste Veranderung fiel bei allen Dunndarmersatzmagen eine starke muskulare Wandhypertrophie auf, die vor allem die Ringmuskulatur betraf. Beim Colonersatzmagen, der physiologisch eine dickere Wandmuskulatur besitzt, war die Hypertrophie sehr viel geringer. Als pathogenetischer Faktor dieser Veranderung gilt die Volumenbelastung, der der Ersatzmagen an dieser …
Risk of Virus Contamination Through Surgical Smoke During Minimally Invasive Surgery: A Systematic Review of the Literature on a Neglected Issue Revi…
2020
Abstract Context The coronavirus disease 2019 (COVID-19) pandemic raised concerns about the safety of laparoscopy due to the risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) diffusion in surgical smoke. Although no case of SARS-CoV-2 contagion related to surgical smoke has been reported, several international surgical societies recommended caution or even discouraged the use of a laparoscopic approach. Objective To evaluate the risk of virus spread due to surgical smoke during surgical procedures. Evidence acquisition We searched PubMed and Scopus for eligible studies, including clinical and preclinical studies assessing the presence of any virus in the surgical smoke fr…
CLINICAL OUTCOMES OF SELF-EXPAMDABLE METALLIC STENTS IN PALLIATION OF MALIGNANT ANASTOMOTIC STRICTURES: A SINGLE CENTER EXPERIENCE
2015
Background: self-expandable metallic stents (SEMS) are employed as the preferred non surgical palliative treatment for gastric outlet obstruction due to malignancies. Metallic stents are often employed to treat malignant anastomotic obstructions after surgicsl interventions as esophagojejunostomy, gastrojejunostomy and esophagogastrojejunostomy. Methods: this case series reports prospectively the clinical outcomes of SEMS in the palliative care of malignant anastomotic strictures caused by the recurrence gastric cancer follwing gastric surgery as oncological curative treatment, in a series of nine consecutive patients, treated between January 2009 and december 2012 in our center. Results: N…

Small bowel obstruction after laparoscopic gastrectomy: An atypical clinical presentation. Report of a case
2020
Abstract Introduction Postoperative adhesions represent the most common cause of acute small bowel obstruction (80%) and are usually a consequence of abdomino-pelvic surgery performed with open technique. Presentation of case A 45-year-old black man arrived at the emergency room with abdominal pain and distension three months after laparoscopic distal gastrectomy with Roux-en-Y anastomosis performed for benign pyloric stenosis. CT abdominal scan revealed some air-fluid levels in the center of the abdomen with distension of proximal jejunal loops caused by intestinal adhesions. Laparoscopic adhesiolysis was performed to restore the intestinal transit. Discussion The formation of adhesions is…
Laparoscopic subtotal gastrectomy for the treatment of advanced gastric cancer: a comparison with open procedure at the beginning of the learning cur…
2017
Background: In the last decades, after some initial concern, laparoscopic subtotal gastrectomy (LSG) is gaining popularity also for the treatment of advanced gastric cancer (AGC). The aim of this study is to compare a single surgeon initial experience on LSG and open subtotal gastrectomy in terms of surgical safety and radicality, postoperative recovery and midterm oncological outcomes. Methods: a case control study was conducted matching the first 13 LSG for AGC with 13 open procedures performed by the same surgeon. Operative and pathological data, postoperative parameters and midterm oncological outcomes were analyzed. Results: There was no significant difference in mortality (0%) and mor…

Revisional bariatric surgery due to failure of the initial technique: 25 years of experience in a specialized Unit of Obesity Surgery in Spain.
2019
Abstract Objectives To evaluate the effectiveness of conversion surgery in a bariatric surgery unit with 25 years of experience. Method Retrospective observational study of patients with type II obesity or higher who were reoperated by means of conversion surgery due to weight regain, residual body mass index (BMI) >35 kg/m2 or Results A total of 112 patients were included, with a mean age of 40.2 years, who initially underwent vertical banded gastroplasty (VBG) (32.1%), gastric banding (GB) (23.2%), Roux-en-Y gastric bypass (RYGB) (21.4%) and sleeve gastrectomy (SG) (23.2%). The conversion techniques, with a median time between the two surgeries of 70 months, included: RYGB, SG, one-anasto…
