Laryngopyocele: three new clinical cases and review of the literature

Laryngopyocele is a fairly rare disease. It is a complication of laryngocele. Its clinical picture is often alarming; thus it needs fast differential diagnosis. Computed tomography allows early diagnosis. Surgical treatment permits a complete recovery. An association between laryngocele and carcinoma of the larynx has been reported by some authors. Three new cases of laryngopyocele are presented and discussed. Received: 23 November 1999 / Accepted: 29 May 2000

The anaesthetist as determinant factor of quality of surgical antimicrobial prophylaxis. A survey in a university hospital.

In actual surgical antimicrobial prophylaxis, the anaesthetist administers the drugs at induction of anaesthesia. In the first phase of our qualityofuse intervention study on antimicrobial drugs in a large university hospital, information on the practice of antimicrobial prophylaxis was needed. The staff of 44 anaesthetists was interviewed by means of a questionnaire. Response rate was 36/44 (82%). The anaesthetists' method of administering surgical prophylaxis was rather uniform and inexpensive: cephalosporins were almost exclusively administered by bolus method. The main reason was that infusion was more cumbersome (range 7785%). Communication between surgeon and anaesthetist was reported to be poor, and in two out of three operating departments, orders of prophylaxis transmitted at or after induction accounted for more than 80%. Seventyseven percent of the responders asked the surgeon if prophylaxis was necessary if they were in doubt; 20% responded that they checked it systematically. The data collected by the inquiry proved useful in the process of optimizing surgical prophylaxis in our hospital.     

Survey on Torino courses

Since March 1991 a monthly course on laparoscopic cholecystectomy has been organized at the Department of Surgery of the University of Turin. To evaluate the impact of this course and to obtain feedback from surgeons in order to improve the teaching of laparoscopic surgery, detailed questionnaires were sent to the participants of the first 20 courses.The outcome of this survey shows that short-residency hands on courses do not represent a completely satisfactory training, either for practicing surgeons or for residents, mainly because of the constraints of time and the lack of proctoring and supervision. Besides, the present study shows a significant difference in the diffusion of laparoscopic surgery in different areas of Italy.However, clinical results reported by this group of surgeons are satisfactory and comparable to the best multicentric series: 2,127 laparoscopic cholecystectomies were performed by 48 surgeons with a conversion rate of 6% and a complication rate of 2.4%.

Einfluß des operationstraumas auf die NK-zell-aktivität beim ösophaguskarizinom nach transmediastinaler dissektion vs. transthorakaler en-bloc-resektion

Zusammenfassung Um den Einfluß des chirurgischen Traumas beim Ösophaguskarzinom auf das zelluläre Immunsystem zu erfassen, wurden perioperativ in einer prospektiven Studie die Aktivität der natürlichen Killerzellen sowie die Serumkonzentrationen von Interleukin-2, Interleukin-6 un TNF- bei transmediastinaler Dissektion (n=12) vs. transthorakaler En-bloc-Resektion (n=10) der Speiserörhre im Vergleich zu einer Kontrollgruppe mit thorakoabdominalen chirurgischen Eingriffen bei nicht maligner Grunderkrankung erfaßt. Die Bestimmung der NK-Zell-Aktivität erfolgte präoperativ sowie am 4. und 10. Tag postoperativ durch einen standardisierten Europiumchlorid-release-Assay unter Verwendung von K-562-Targetzellen, die Lymphokine Interleukin-2, Interleukin-6 und TNF- wurden zusätzlich am 1. und 7. Tag postoperativ mit stadardisierten ELISA-Assays bestimmt.In unserem Patientengut sank die NK-Zellaktivität am 4. postoperrativen Tag sowohl in der Kontrollgrupe al auch bei beiden Operations verfahren zur Speiseröhrenresektion signifikant (p<0,05) zum Ausgangswert: in der Kontrollgruppe durchschnittlich um 45%, nach transmediastinaler Speriseröhrendissektion (1-Höhlen-Eingriff) durchschnittlich um 34%, nauch transthorakaler En-bloc-Resektion (2-Höhlen-Eingriff) im Mittel um 63% zum präoperativen Wert. Die transthorakale En-bloc-Resektion der Speiseröhre führte durch das größere chirurgische Trauma zu einer stäkeren Abnahme der zytotoxischen Aktivität der natürlichen Killerzellen. Eine Suppression der immunologischen Tumorabwehr insbesondere in der vulnerablen perioperativen Phase kann damit indirekt das Risiko der Manifestation von hämatogene Metastasen auf dem Boden einer intraoperativen Tumorzelldissemination u. a. bedingt durch Tumormanipulation begünstigen und damit prognostisch relevant werden.

Influence of surgical trauma on natural killer cell activity in esophageal carcinoma following transmediastinal dissection compareed with transthoracic en bloc resection

In order to assess the impact of surgical trauma involved in the therapy of esophageal carcinoma on the cellular immune system, a perspective study was performed involving perioperative hematological parameters. The activity of natural killer cells and the serum concentrations of interleuin-2, interleukin-6 and TNF- were measured in 12 cases of transmediastinal dissection and 10 cases of transthioracic en bloc esophageal resection and compared to values of a control group of thoracic and abdominal surgical patients with non-malignant maladies. Natural killer cells assume a central role in the non-specific immunological response in tumor patients. Their main function is the destruction of tumor cells via cytotoxic activities amplified by the release of interleukin-2 and TNF-. Natural killer cell activity was measured prior to surgery and on postoperative days 4 and 10 using a standardized europium chloride release assay, utilizing K 562 target cells. Lymphokines interleukin-2, interleukin-6, and THF- were also measured on postoperative days 1 and 7 using standardized ELISA assays. The activity of natural killer cells in our patient group sank significantly (P<0.05) on postoperative day 4 and likewise in the control group and both study groups, activity sank to the original values. In the control groups, natural killer cell activity averaged 45% of preoperative values, in comparison with an average of 63% following transmediastinal esophageal carcinoma resection (one cavity procedure), and transthoracic en bloc resection patients only reached 61% of preoperative values, transmediastinal dissection patients assumed 75%, and 77% was achieved by control group members. Transthoracic en bloc resection of the esophagus led to a more extreme reduction in cytotoxic cellular activity owing to the greater surgical trauma. Suppression of the immunological tumor resistance, especially in the vulnerable perisurgical pahse, can have an indirect negative effect on the manifestation risk of hematogenic metastases owing to intraoperative tumor cell dissemination resulting from tumor manipulation and may thus be prognostically relevant.

     

Duodenal and jejunal atresia with agenesis of the dorsal mesentery: "apple peel" small bowel.

Two newborn infants with duodenal and jejunal atresia and agenesis of the dorsal mesentery represent our surgical experience with "apple peel" small bowel or "christmas tree" demormity. The first patient had the typical appearance of this condition. The postoperative course was complicated by hyperbilirubinemia, septicemia, and disseminated intravascular coagulation. The infant is in satisfactory condition 1.5 years after operation. The second patient had agenesis of the dorsal mesentery without spiraling of the bowel around its vascular stalk. The child died after 1 month, with complete absence of extrahepatic bile ducts as seen at a second laparotomy. Neither child had been subjected to gastrostomy.
