Three-dimensional (3D) versus two-dimensional (2D) laparoscopic adrenalectomy: A case-control study
2016
Abstract Introduction Laparoscopic adrenalectomy is today considered the gold standard of treatment for adrenal tumors. The development of high definition cameras does not eliminate the major limitation of two-dimensional (2D) laparoscopy: lack of depth perception and loss of spatial orientation. Tree-dimensional (3D) HD laparoscopy was developed as an alternative to conventional 2D laparoscopy. Methods We report our experience with use of 3D vision system for laparoscopic adrenalectomy. Between January 2009 and March 2015 we performed a total of 52 laparoscopic adrenalectomies. In this case-control study we considered 13 laparoscopic adrenalectomies performed with three-dimensional (3D) vi…
Prediction of complexity and complications of laparoscopic liver surgery: The comparison of the Halls‐score to the IWATE‐score in 100 consecutive lap…
2020
BACKGROUND The development of laparoscopic liver surgery is slower than in other disciplines. Two different scoring systems have been proposed to estimate difficulty of laparoscopic liver resections (LLR) preoperatively. The aim of this analysis was to compare these two scores in an independent patient cohort regarding the predictability of morbidity. METHODS All LLRs performed between 01/2011 until 01/2019 were identified from our prospective institutional database. Patient characteristics as well as intra- and postoperative data were analyzed. Postoperative complications were graded according to Dindo-Clavien classification. Difficulty of LLR was classified using IWATE- and Halls-score. R…
Recurrence of pleomorphic adenoma of the parotid gland-predictive value of cadherin-11 and fascin
2008
The predictive value of cadherin-11, tenascin, fascin, and mucin-1 as markers for the likelihood of recurrence in pleomorphic adenoma of the parotid gland was examined. In this retrospective study we analysed 20 tumours from16 patients by immunohistochemistry. Staining intensities were measured using a semiquantitative scoring approach; localisation (tumour centre vs border) as well as clinical data were analysed and correlated with follow-up. Cadherin-11 was increased in recurrent tumours. However, no changes of fascin, tenascin or mucin-1 were observed. Cadherin-11 and fascin were increased in primary tumours of patients with later recurrence, with fascin upregulation restricted to the tu…
The Laparoscopic Approach to Control Intractable Pelvic Neuralgia: From Laparoscopic Pelvic Neurosurgery to the LION Procedure
2007
OBJECTIVE: To present different aspects and advantages of the laparoscopic approach to the pelvic nerves aimed at treating intractable pelvic neuralgia. METHODS: We report on a nonconsecutive series of 7 patients with different types and etiologies of chronic pelvic neuralgia, all of whom underwent laparoscopy. In all 7 cases, the neuralgia was refractory to medical management and had profound socioeconomic consequences for the patients. RESULTS: Techniques of laparoscopic transperitoneal neurolysis of several pelvic somatic nerves are described but also our technique of laparoscopic implantation of neuroprothesis for neuromodulation on somatic pelvic nerves or on autonomic pelvic nerves as…
TheMAOA T941G polymorphism and short-term treatment response to mirtazapine and paroxetine in major depression
2006
This study investigated the possible association of the MAOA T941G gene variant with differential antidepressant response to mirtazapine and/or paroxetine in 102 patients with major depression (DSM-IV criteria) participating in a randomized double-blind controlled clinical trial. Female mirtazapine-treated patients homozygous for the T-allele had a significantly faster and better treatment response than TG/GG-patients. In males, we failed to show an association between MAOA T941G gene variant and mirtazapine response. In the paroxetine-treated group, there were no significant differences in treatment response between MAOA T941G genotype groups. Time course of response and antidepressant eff…
Tumors of the salivary gland in Mexicans. A retrospective study of 360 cases
2011
Objective: To establish distribution frequency and demographic characteristics of salivary gland tumours (SGT) i6n order to identify possible risk profiles. Design of study: The present report constitutes an eight year retrospective study (January 2000-August 2007). The archives of the Clinical and Experimental Pathology Laboratory (Graduate and Research Division, Dental School, National Autonomous University of Mexico) as well as archives of the Surgical Pathology Service (General Hospital, Mexico City) were subject to revision in order to select all cases where SGT tumour diagnoses were emitted. Age and gender of patients as well as SGT topography were obtained from medical records. Selec…
Evaluation of labial microvessels in Sjogren syndrome: A videocapillaroscopic study
2008
Summary Sjogren's syndrome (SS) is a chronic autoimmune rheumatic disease characterized by a progressive lymphocytic infiltration of exocrine glands, especially salivary and lachrymal ones, leading to xerostomia, parotid gland enlargement, and xerophtalmia. SS may occur alone (primary) or in association with almost any of the autoimmune rheumatic diseases (secondary), the most frequent being rheumatoid arthritis. The aim of this study is to describe the capillaroscopic pattern of the labial mucosa in patients with SS. Methods A total of 20 patients affected by SS and 20 healthy controls were examined. The patients with conditions that compromise microcirculation, such as diabetes, hypertens…
Lymphadenomatous carcinoma of the sublingual gland: report of a first case in an unusual localization.
2008
Background. Lymphadenomatous carcinoma of the salivary gland is a very rare tumor, which hitherto occurred exclusively in the parotid gland. This report describes a case of lymphadenomatous carcinoma of the sublingual gland, which is thought to be the first report of this special entity. Methods and Results. A 36-year-old man was seen with slowly growing mass on his right floor of mouth. Upon surgical removal, the mass was well encapsulated. Microscopic exami- nation revealed a biphasic appearance with islands of neoplas- tic epithelial cells presenting against a dense lymphoid stroma, while the epithelial compartment showed features of malig- nancy. During 30-months of close follow-up, the…
SDHB Expression in Warthin's Tumour
2011
Abstract Introduction Succinic dehydrogenase subunit B (SDHB) is an enzyme belonging to the mitochondrial complex II. The aim of this study is to analyse SDHB expression in a series of Warthin's tumours, studying its relationship with oncocytic changes, constantly present in this form of tumour. Material and methods In resection tumour specimens from a series of ten Warthin's tumours (all from the parotid gland), immunohistochemical expression of SDHB was analysed using a commercially available monoclonal antibody. Results The Warthin's tumours studied affected 10 men (mean age: 64.2 yrs, range 40–80), all with smoking habits, and 2 with metachronous bilateral involvement. Two patients pres…
Minilaparoscopy-guided spleen biopsy in systemic disease with splenomegaly of unknown origin.
2002
With the advent of a minimally invasive laparoscopy technique, the advantages of diagnostic laparoscopy are being rediscovered. We report here on four patients with systemic disease of unknown origin and splenomegaly, in whom minilaparoscopy-guided splenic biopsy yielded a definitive diagnosis. Four patients with unclear systemic disease were studied using diagnostic minilaparoscopy and guided spleen biopsy, after failure of diagnostic work-up. Minilaparoscopic spleen biopsy revealed the diagnosis of a B-cell non-Hodgkin's lymphoma in two cases. In one patient, who had a history of Still's disease, the spleen biopsy showed granulocytic infiltration in the spleen typical of an acute episode …
