Robotic transanal total mesorectal excision: Is the future now?
2021
Total mesorectal excision (TME) is the standard surgical treatment for the curative radical resection of rectal cancers. Minimally invasive TME has been gaining ground favored by the continuous technological advancements. New procedures, such as transanal TME (TaTME), have been introduced to overcome some technical limitations, especially in low rectal tumors, obese patients, and/or narrow pelvis. The earliest TaTME reports showed promising results when compared with the conventional laparoscopic TME. However, recent publications raised concerns regarding the high rates of anastomotic leaks or local recurrences observed in national series. Robotic TaTME (R-TaTME) has been proposed as a nove…
Corporeïtat, conflicte i abjecció en Les mans de la deixebla d?Anna Moner
2019
Resum: Aquest article té per objectiu analitzar la novel·la Les mans de la deixebla d’Anna Moner (2011) com una obra a cavall entre la narració gòtica i l’ambientació històrica en el segle xviii, d’una banda, i com a exponent de la representació de la corporeïtat, d’una altra. Estudiem els mecanismes a través dels quals l’autora construeix tres personatges complexos que giren al voltant del conflicte generat per la naturalesa abjecta (Kristeva 2006) del cos de la protagonista. A partir d’aquest punt, ens proposem explorar com les mans deformades esdevenen un símbol que connecten amb la tradició gòtica (Cornich i Sedgwick 2017) i que en aquesta novel·la funcionen com un agent que distorsiona…
Comparison between Laparoscopic and Robotic Approach for Sentinel Lymph Node Biopsy in Endometrial Carcinoma Women
2022
Robotic surgery has been approved as an alternative to laparoscopy to improve surgical outcomes. There is neither a consensus nor a systematic assessment of the literature about the superiority of the robotic approach over the laparoscopic one for sentinel lymph node (SLN) biopsy in endometrial carcinoma (EC) women. Therefore, a systematic review and meta-analysis was performed to compare the laparoscopic and robotic approaches for SLN biopsy in EC patients. Five electronic databases were queried from their inception to May 2022 for peer-reviewed studies, comparing such approaches in SLN biopsy in EC patients. The rate of detected SLN, dissected SLN, intraoperative and postoperative complic…
Impact of Obesity on Sentinel Lymph Node Mapping in Patients with apparent Early-Stage Endometrial Cancer: The ObeLyX study
2022
Conflicting data exists on the impact of Body Mass Index (BMI) on sentinel lymph-node (SLN) detection. The primary study endpoint was to investigate the impact of obesity on overall detection rate, bilateral mapping, and mapping failure rate of SLN. In addition, we evaluated possible differences in terms of surgical management and "empty-packet dissection" rate among obese and non-obese patients.Multicenter, propensity-matched, retrospective study. Patients with apparent early-stage endometrial cancer were included. Study population was divided into women with BMI/≥ 30 (Group-1 and Group-2). To lower the selection bias, a propensity-matched analysis was performed. Matching was based on hist…
Mapping of the perigastric lymphatic network using indocyanine green fluorescence imaging and tissue marking dye in clinically advanced gastric cance…
2022
Abstract Background Using indocyanine green (ICG) fluorescence imaging and tissue marking dyes (TMDs), perigastric lymphatic mapping and their pathological correlation were examined to see whether ICG staining covers all metastatic lymph nodes (LNs) in advanced gastric cancer (AGC). Methods Patients with AGC who underwent open distal or total gastrectomy were enrolled. ICG was serially injected intraoperatively into the subserosa along the greater and lesser curvatures. Stomach specimens were examined under a near-infrared camera. ICG-stained LNs were named, excised, and tattooed with different colored TMDs to retrace the exact location after pathological examinations. Results A total of 68…
Keratinocytes Determine Th1 Immunity during Early Experimental Leishmaniasis
2010
Experimental leishmaniasis is an excellent model system for analyzing Th1/Th2 differentiation. Resistance to Leishmania (L.) major depends on the development of a L. major specific Th1 response, while Th2 differentiation results in susceptibility. There is growing evidence that the microenvironment of the early affected tissue delivers the initial triggers for Th-cell differentiation. To analyze this we studied differential gene expression in infected skin of resistant and susceptible mice 16h after parasite inoculation. Employing microarray technology, bioinformatics, laser-microdissection and in-situ-hybridization we found that the epidermis was the major source of immunomodulatory mediat…
The occlusive tourniquet: a simple method for rectal stump washout during open and laparoscopic surgery.
2007
Rectal stump washout with cytolytic agents is recommended and usually performed during anterior rectal or rectosigmoid resection. The use of a linear stapler instrument during ultralow anterior resection makes the placement of pelvic clamps difficult for rectal stump washout prior to resection. The objective of this work is to demonstrate the use of a simple procedure, the occlusive tourniquet for rectal stump washout. Occlusive tourniquet applied to open technique: after complete dissection of the rectum and sigmoid colon according to the usual technique, a simple piece of tubing from an intravenous line is passed behind and around the rectum/sigmoid colon at some point distal to the tumor…
Surgical management of benign tracheal stenosis.
2014
Abstract This chapter provides a step-by-step explanation of the indications, basic technique and pitfalls of tracheal surgery for cases of benign tracheal stenosis. Approach, trachea dissection and end-to-end anastomosis in tracheal surgery is described in detail. An algorithm for laryngotracheal technique selection according to different criteria (stenosis location, vocal cords status and tracheal mucosa and/or cartilaginous larynx involvement) is also depicted. Finally, a review of the most important reported series in tracheal surgery is presented.
[Use of imaging criteria to identify cervical metastases using CT scans in head and neck tumours].
2008
Abstract Objective To assess the diagnostic certainty of CT images to identify regional spread of head and neck tumours. Patients and method A CT study was performed on 86 patients with neoplasms in the larynx and/or pharynx. After this, surgical dissection was performed for 142 neck sides. In the imaging study the following parameters were considered for all patients before suspecting malignant nodes: size of adenopathy bigger than 10–11 mm, irregular borders, central necrosis, spherical shape, capsular enhancement, and presence of groups with 3 or more lymphadenopathies. Results 48.5% of dissections were N+. Sensitivity and specificity for physical examination were 59% and 82%, respective…
Blutungen nach CO2-laserchirurgischer Tumorentfernung im HNO-Bereich
2004
Background: There are different reports in the literature how often postoperative hemorrhage occurs after laser resection of head-and-neck tumours. This retrospective study investigates the frequency of postoperative hemorrhage after laser surgery of head and neck tumours. Time and extent of bleeding have been considered as well as the localization of the primary tumour and possible general risk factors. Methods and Patients: Between 1998 and 2001, microscopic laser surgery was performed in 223 patients with previously untreated squamous cell carcinomas of the oral cavity, oropharynx, supraglottic and glottic region and the hypopharynx. In case of ultrasonographic or palpable evidence of ce…
