The goal of this report is to analyse the incidence of genital tumours in cattle referred to the Clinic between 2016 and 2019 and to describe the outcome after the surgical tumour resection. All cattle with a confirmed diagnosis of a genital tumour (n = 3) were included in the study. The breed, age, tumour localisation and type of treatment were considered. Telephone interviews were used to ask owners about the integration of the cows into the herd after discharge, the survival, the reason for leaving the herd, wound complications and tumour recurrence. Three genital tumours including a vaginal fibrosarcoma, vaginal leiomyosarcoma and luteoma were diagnosed. A tumour recurrence or metastasis did not occur. In conclusion, the tumour resection was successful in all three cases. To our knowledge, this is the first clinical description of a cow with a luteoma.

Besides the conventional extracorporeal circulation, commonly used in cardiac surgery, the methods of extracorporeal life support (ECLS) have been applied ever more frequently in thoracic surgery in recent years. The most commonly used modalities of such supports include extracorporeal membrane oxygenation (ECMO) and the Novalung interventional lung assist device (iLA). Successful application of ECLS has led to its more frequent use in general thoracic surgery, especially as a tool to treat hypercapnia and to ensure oxygenation and haemodynamic support. However, these methods are essential in lung transplant programmes; without their help, in most cases, it would not be possible to perform the transplantatioz or prevent the severe complications associated with critical primary graft dysfunction. Additionally, the extracorporeal circulation also facilitates the performing of specific surgical procedures that would not be feasible under standard conditions or would be associated with an inadequate risk. The application of extracorporeal life supports can fundamentally increase the level of resection when treating advanced intrathoracic malignancies that are in close contact with the heart and large vessels or even directly extend into them. Without the possibility of resecting such structures en bloc, together with the tumour, and, thus, achieving an R0 resection, these malignant tumours are often directly contraindicated for surgery or are operated non-radically, i.e. unsuccessfully. Complete tumour resection is the most important prognostic factor in the surgery.

Abstract Purpose Resection site repair during laparoscopic oncological surgery (e.g. laparoscopic partial nephrectomy) poses some unique challenges and opportunities for augmented reality (AR) navigation support. This work introduces an AR registration workflow that addresses the time pressure that is present during resection site repair. Methods We propose a two-step registration process: the AR content is registered as accurately as possible prior to the tumour resection (the primary registration). This accurate registration is used to apply artificial fiducials to the physical organ and the virtual model. After the resection, these fiducials can be used for rapid re-registration (the secondary registration). We tested this pipeline in a simulated-use study with $$N=18$$ N = 18 participants. We compared the registration accuracy and speed for our method and for landmark-based registration as a reference. Results Acquisition of and, thereby, registration with the artificial fiducials were significantly faster than the initial use of anatomical landmarks. Our method also had a trend to be more accurate in cases in which the primary registration was successful. The accuracy loss between the elaborate primary registration and the rapid secondary registration could be quantified with a mean target registration error increase of 2.35 mm. Conclusion This work introduces a registration pipeline for AR navigation support during laparoscopic resection site repair and provides a successful proof-of-concept evaluation thereof. Our results indicate that the concept is better suited than landmark-based registration during this phase, but further work is required to demonstrate clinical suitability and applicability.

The differential diagnosis for precocious puberty in a young female includes peripheral causes. This case report documents a rare cause of isosexual precocious puberty, a juvenile granulosa cell tumour of the ovary–and a brief literature review. A one year-old baby girl presented with mass abdomen, vaginal discharge and rapid onset of pubertal development. She underwent an exploratory laparotomy for tumour resection. Pathology reported a juvenile granulosa cell tumour of the ovary. Early stage granulosa cell tumor surgically treated has good prognosis. Adjuvant chemotherapy is not indicated in this setting.
