    Description / Table of Contents: Résumé. Depuis les premières publications par Raynaud et Trousseau, l'association d'une pathologie maligne occulte et d'une atteinte vasculaire périphérique a été largement reconnu. Récemment, un certain nombre de oas ont été publiés d'ischémie digitale monophasique aiguë due à une lésion maligne occulte. Il apparît que le siège et le type de la tumeur sont non significatifs quant au développement de l'ischémie alors même que la résec-tion de la tumeur résulte dans une rapide amélioration des lésions digitales. Le mécanisme doit encore être établi.
    Notes: Abstract. Since the early transcripts by Raynaud and Trousseau, there has been wide acceptance of the association of occult malignancy and peripheral vascular disease. Recently, there have been a few case reports of acute onset monophasic digital ischemia heralding an occult malignancy. It appears that the site and tumor types seem unimportant in the development of ischemia; tumor resection however, usually results in rapid improvement of the affected digit. The mechanism remains to be established.

    A method of objectively evaluating improvements in laparoscopic skills (1998)

    Notes: Abstract Background: In this paper, we explored a quick and inexpensive method to evaluate the improvement in laparoscopic skills gained by residents after attending a formal training course in laparoscopy. Methods: Surgical residents attending an endoscopic workshop were randomly selected to perform tasks in a training simulator. Each was evaluated qualitatively and quantitatively before and after the workshop. A control group of six residents who did not attend the workshop were selected to perform the same tasks twice in succession. Results: The total mean time improvement for all tasks in the study group was 34.3% and in the control group 7.3% (p= 0.0001). When the data was separated for each task, statistically significant improvement was demonstrated in five of the six tasks. Conclusions: Residents who attend a formal workshop in endoscopy can gain significant improvement in skills. The methods described in this study can be used to quantitatively measure this improvement throughout a resident's training.

    Utility of insufflation filters in laparoscopic surgery (1998)
    Springer
    Surgical endoscopy and other interventional techniques 12 (1998), S. 1137-1140

    Topics: Medicine
    Notes: Abstract Objectives: To determine whether filters, regularly used as part of the insufflator tubing during laparoscopic surgery, trap microbial and particulate matter from CO2 tanks, thus preventing passage from one patient to another. Methods: A total of 67 used filters were collected from 17 CO2 tanks and six insufflation machines at three local hospitals, and sterile unused filters were used as controls. The used filters were distributed equally and sequentially into three groups: Group I—viewed under a dissecting microscope for particulate matter; group II—examined by mass spectrometry for contamination with oils and other impurities; group III—incubated on sheep blood agar plates and evaluated for growth of microorganisms. Results: Negative. Used filters were indistinguishable by all parameters from controls. Conclusions: This limited study suggests filters now used in laparoscopic surgery fail to trap microbes or particulate matter. The question remains whether tank waste is absent or these filters fail to trap waste matter.

    Endoscopic axillary exploration and sentinel lymphadenectomy (1999)

    Notes: Abstract Background: Minimally invasive approaches have changed the practice of surgery in several specialties. The purpose of this study was to develop a reproducible endoscopic technique for the evaluation of the axilla in breast cancer patients. Methods: A total of 23 patients with biopsy-proven breast carcinoma were enrolled. Patients were positioned in the supine position with the ipsilateral arm abducted at 90°. A 1-cm skin incision was made at the superior aspect of the axilla. Dissection was carried bluntly to the lateral border of the pectoralis major. A balloon distention device was inserted into the tract and distended under endoscopic vision to create a working space. Insufflation was initiated up to a pressure of 8 mmHg. A 30° laparoscope was introduced for visualization of axillary contents. One or two additional 5-mm cannulas were placed as needed under direct visualization. Manipulation of axillary contents was performed, and in 19 patients a sentinel node identification technique was applied. Results: In all patients, using insufflation and minimal instrument dissection, the axillary vein, long thoracic, and thoracodorsal nerves were found in their usual anatomical locations. Utilizing blunt and sharp dissection, the axilla was thoroughly inspected, and individual lymph nodes were easily identified and extracted. In 11 of 19 patients, a sentinel node or blue dye was identified using isosulfan blue. There was a procedure concordance of 84%, and there were no complications. Conclusions: We describe a novel endoscopic technique for the evaluation of the axilla in breast cancer patients. This technique allows (a) creation of a minimally invasive working space within the axilla, (b) recognition of key axillary anatomic landmarks, and (c) instrument manipulation within the axilla to identify and extract lymph nodes, and apply the sentinel node technique. This is the first report of a minimally invasive approach to axillary exploration to employ sentinel lymph node mapping.

    Keywords: Key words: Adhesions — Herniorraphy — Inguinal hernia repair — Laparoscopy — Peritoneum — Totally extraperitoneal

    Topics: Medicine
    Notes: Abstract Background: The laparoscopic approach to hernia repair has been advocated by many as a potentially superior method of herniorraphy. Several techniques have been described, each with its own proposed advantages. These techniques involve different anatomic approaches, the most recent of which is the totally extraperitoneal approach (TEPA). One presumed advantage of the extraperitoneal approach is the avoidance of adhesion formation because the peritoneum is not entered and mesh is not placed in direct contact with intra-abdominal structures. We hypothesize, however, that when the peritoneum is dissected from the abdominal wall, it is partially devascularized, leading to scar formation and potential adhesion formation. This would suggest that the TEPA method of herniorraphy may not completely avoid the risks of intra-abdominal adhesion formation. Methods: After appropriate approval was obtained, 88 male Sprague-Dawley rats were divided into two equal groups. One group underwent laparotomy followed by careful blunt dissection of the peritoneum from the left abdominal wall. The control group underwent laparotomy without manipulation of the peritoneum. All animals were re-explored 14 days later, and the abdominal cavity was examined for adhesions. The type and location of any adhesion was recorded. Results: Adhesion formation occurred in 10 of 44 (23%) subjects in the peritoneal dissection group, compared with 3 of 44 (7%) in the nondissection group (p 〈 0.05). Conclusions: Dissection of the peritoneum from the overlying abdominal wall in the murine model leads to intra-abdominal adhesion formation. This suggests that peritoneal dissection in the TEPA method of herniorraphy may lead to intra-abdominal adhesion formation.
