Advanced Endoscopic Imaging Methods
2021
Endoscopic imaging is the mainstay of gastrointestinal endoscopy and has experienced remarkable improvements in recent decades. Further endoscopic innovations stemming from major technological advances such as artificial intelligence and deep learning are at advanced stages of development and will be increasingly deployed in routine clinical practice. These will improve the detection and enable real-time optical diagnosis of pathologies in the gastrointestinal tract. Furthermore, the utilization of endoscopic robots may result in higher diagnostic yield and greater patient comfort. This chapter covers the most recent developments around computer-assisted diagnosis, hypoxia and three-dimensi…
Stump appendicitis. A case report
2016
Highlights • Stump appendicitis (SA) is a rare, but noteworthy, diagnosis that warrants early detection. • Delay in the diagnosis of SA may result in serious complications like stump gangrene, perforation and peritonitis. • More research is needed to identify strategies to prevent SA. • We underline the emergent role of lower endoscopy to clarify diagnosis resolve the symptoms. • Surgeons need to have a heightened awareness of the possibility of SA.
The "neurologic hypothesis": A new concept in the pathogenesis of the endometriosis?
2005
To cartograph the retroperitoneal infiltration of deep-infiltrating endometriosis of the rectovaginal space, we report on 467 patients who underwent laparoscopic/vaginal surgery for deep-infiltrating adenomyosis of the rectovaginal space. Exact localisation of the locoregional extension and of secondary infiltrating localisation where noted. The cervix and the rectovaginal ligament were mostly involved, while isolated lesions of the rectovaginal space were very rare. Comparisons of the most involved sites show an absolute correlation with the anatomical repartition of the pelvic sympathetic nervous system. We postulate a new "neurologic theory" which could be one more explanation for the de…
Endometrial cancer: Robotic versus Laparoscopic treatment. Preliminary report
2015
Laparoscopic approach is today the standard treatment for benign and malignant gynecological pathologies. To traditional laparoscopic surgery in the last 10 years we can add the possibility to use a robotic platform. The adoption of this system allows undoubted advantages as the three-dimensional vision, the absence of the physiological tremor with enhanced ergonomics and possibility of using articulable tools. In this study we analyzed the results of 18 patients with endometrial cancer (Stage I) treated with robotic approach. The results were compared with a selected sample of 26 patients, with the same characteristics, treated with traditional laparoscopic approach in the same period by t…
Enhanced Endoscopy in Inflammatory Bowel Disease
2011
Enhanced imaging technologies are of special importance in patients with inflammatory bowel diseases. Patients with long-lasting colitis face an increased cancer risk and neoplastic changes often evolve as subtle, multifocal, and flat lesions. Enhanced endoscopic imaging technologies enable better visualization of the mucosal architecture. These new available information can be used to better detect and characterize colorectal lesions. The better endoscopic judgment leads to more targeted biopsies and cancer detection can be facilitated. This new concept of “smart biopsies” is in particular important for screening purposes. Furthermore, the technique of endomicroscopy enables in vivo histol…
Differentiation between brain metastases and glioblastoma multiforme based on MRI, MRS and MRSI
2009
Brain metastases and glioblastoma multiforme are the most aggressive and common brain tumours in adults and they require a different clinical management. Anatomical magnetic resonance imaging (MRI) or clinical history, cannot always clearly distinguish between them. This study describes and verifies the use of magnetic resonance spectroscopy (MRS) and magnetic resonance spectroscopic imaging (MRSI) in combination with MRI for differential diagnosis of glioblastomas and metastases. Feature selection methods are applied to the magnetic resonance (MR) spectra of 121 patients and relevant features are detected. Different classification methods are used to distinguish glioblastoma multiforme and…
Mirizzi syndrome in a patient with partial gastrectomy with Billroth II anastomosis: A case report
2020
Highlights • Obstructive jaundice may be a challenge for differential diagnosis. • Mirizzi Syndrome may simulate clinical and radiological presentation of common bile duct stones. • ERCP hardly achieves cannulation of biliary duct in altered anatomy, so gastroscope may be a correct choice in these cases. • Surgical treatment is essential in Mirizzi Syndrome.
Unusual giant chromophobe renal cancer totally managed with laparoscopic technique: Report of a case
2020
Highlights • We describe a case report of giant renal cell chromophobe carcinoma totally treated by laparoscopic surgery. • The size of renal lesion represents a critical point in surgical approach because to perform a laparoscopic radical nephrectomy can be challenging even for skilled surgeons in giant renal tumors. • A brief review of literature was performed to identify outcomes and potentially surgical advantages of laparoscopic approach for retroperitoenal liposarcoma. • The possibility of the laparoscopic approach derives from from the preoperative identification of adipose cleavage, from the absence of invasion of major vascular axes, from the absence of distant metastatic lesions.
Interstitial Pregnancy: A 'Road Map' of Surgical Treatment Based on a Systematic Review of the Literature.
2014
An electronic search concerning the surgical approach in cases of interstitial pregnancy from January 2000 to May 2013 has been carried out. Fifty three studies have been retrieved and included for statistical analysis. Conservative and radical surgical treatments in 354 cases of interstitial pregnancy are extensively described. Hemostatic techniques have been reported as well as clinical criteria for the medical approach. Surgical outcome in conservative versus radical treatment were similar. When hemostatic techniques were used, lower blood losses and lower operative times were recorded. Conversion to laparotomy involved difficulties in hemostasis and the presence of persistent or multipl…
Inguinal hernia repair in German military hospitals.
2005
ABSTRACT The inguinal hernia repair continues to be the most common operation in general surgery. Discussing the latest scientific findings, we have prepared this article to present a state-of-the-art approach to the inguinal hernia repair. This approach is used for discussing the general principles of hernia repair in German military hospitals. Quality assurance requires that all hernias be classified during surgery on the basis of a standardized approach for an objective comparison of treatment and outcomes. Our approach to hernia repair considers the age of the patient, the diameter and location of the hernia and whether or not the herniation is recurrent. The Shouldice technique perform…
