Information about the patient (identification number, age, body weight, breed, surgery date), surgical duration, surgical method, surgical site, intra- and postoperative complications, mean arterial blood pressure (MAP), endtidal CO2, (EtCO2), ventilation mode and body temperature during surgery was gathered retrospectively. Surgical duration was evaluated via a linear model with an interaction between weight and methods. Complications were analyzed using Fisher’s exact test for count data, binary logistic regression, Poisson regression models and linear mixed models. MAP was specifically analyzed via a linear model with an interaction between ventilation mode and body weight. There were 46 cases: 22 laparotomies and 24 laparoscopies. Surgical duration increased with body weight. This effect was stronger in laparotomies (p=0.0006) but was also seen in laparoscopies (p=0.034). Surgical duration also increased with age (p=0.03). Mean arterial pressure was lower in laparoscopies (p=0.031). For ventilated dogs, MAP decreased with body weight (p=0.0012). Higher body weight was associated with lower odds of developing moderate hypothermia but a greater likelihood of mild hypothermia (p=0.029). Temperature was lower in older animals (p=0.019) and higher for prolonged surgical durations (p=0.036). Patients that breathed exclusively spontaneously had higher body temperatures than dogs that were exclusively ventilated (p=0.014). Endtidal CO2 decreased with age (p=0.007). In conclusion, larger dogs may profit from laparoscopic approach. eng Vergleich zweier Methoden zur operativen Entfernung kryptorchider Hoden Comparison between two methods for surgical removal of cryptorchid testes Vergleich zweier Methoden zur operativen Entfernung kryptorchider Hoden acnumber:AC17956655 doi:10.34876/ece4-gs15 https://phaidra.vetmeduni.ac.at/o:5531 Diploma thesis - University of Veterinary Medicine Vienna - 2026 The aim of this diploma thesis was to compare surgical duration and complications of laparoscopic and open cryptorchidectomy in dogs.

Diplomarbeit - Veterinärmedizinische Universität Wien - 2026 In dieser Diplomarbeit wurden Operationsdauer und Komplikationen bei laparoskopischen und offenen Kryptorchidektomien bei Hunden verglichen. Dafür wurden retrospektive Informationen zum Tier (Identifikationsnummer, Alter, Gewicht, Rasse, Operationsdatum), die Dauer des Eingriffs, die Methode, der Situs, intra- und postoperativen Komplikationen und der intraoperative mittlere arterielle Blutdruck (MAP), Entidales CO2 (EtCO2), Ventilationsmodus und innere Körpertemperatur gesammelt. Die Operationsdauer wurde mithilfe eines linearen Modells analysiert, das die Interaktion zwischen Körpergewicht und Operationsmethode berücksichtigte. Komplikationen wurden mittels Fisher’s Exact Test für Zähldaten, binärer logistischer Regressionsmodelle, Poisson-Regressionsmodelle und linearen gemischten Modellen analysiert. MAP wurde zusätzlich mit einem linearen Modell mit Interaktion zwischen Ventilationsmodus und Gewicht analysiert. Insgesamt wurden 46 Fälle aufgenommen, bestehend aus 22 Laparotomien und 24 Laparoskopien. Es konnte gezeigt werden, dass schwerere Hunde längere Operationsdauern hatten. Dieser Effekt bestand stärker für die offenen Eingriffe (p=0,0006), aber auch für Laparoskopien (p=0,034). Außerdem dauerte die OP bei älteren Hunden länger (p=0,03). Der MAP war niedriger in Laparoskopien (p=0,031). Bei ventilierten Hunden sank der MAP abhängig vom Gewicht (p=0,0012). Schwerere Hunde hatten eine geringere Wahrscheinlichkeit für moderate Hypothermie (p=0,029). Zudem war das Alter negativ mit der Temperatur assoziiert (p=0,019), während die OP-Dauer positiv mit der Temperatur assoziiert war (p=0,036). Patienten, die nur spontan atmeten, hatten höhere Temperaturen als jene, die ausschließlich ventiliert wurden (p=0,014). Das Alter war negativ mit dem Endtidalen CO2 assoziiert (p=0,007). Vor allem größere Hunde könnten von einer laparoskopischen Entfernung des kryptorchiden Hodens profitieren, da hier Zeit eingespart werden kann.
