“…Jacksons et al (14) reported that opening a 4-5 cm diameter pericardial window is sufficient to eliminate clinical symptoms in thoracic partial pericardiectomy. It has been reported that a more widely formed pericardial window cup could cause clotting from this hole (10). In this study, a 3x3 cm pericardial window was opened in a Miniature Pinscher.…”

“…The thoracoscopic partial pericardiectomy procedure was applied with the paraxiphoid-trandiaphragmatic approach to the first ten patients and with the intercostal approach to the remaining ten (10). The first trocar was positioned immediately below the xiphoidal cartilage, directed to the thorax and when the thoracic cavity was reached, the trocar valve was opened and pneumothorax was created.…”

Thoracoscopy is a minimally invasive imaging method used in the imaging of the thoracic cavity. In comparison with thoracotomy, thoracoscopy provides better visualization of even the smallest lesions localized in the thoracic cavity. With the use of thoracoscopy, the operation stress in the patient and tissue trauma are reduced, and operating time is shortened. The aim of this study was to evaluate 20 dogs with severe pericardial effusion, which manifested as severe circulation disorder and respiratory distress. The patients determined with pericardial effusion as a result of radiographic and echocardiographic examinations were applied with partial pericardiectomy to achieve permanent health and it was decided to apply this with the minimally invasive thoracoscopic method. The paraxiphoid-transdiaphragmatic approach was applied to the first ten patients and the intercostal approach to the latter. Applicability of thoracoscopic partial pericardiectomy, advantages compared to open surgery, differences between two approach techniques, disadvantages, complications, and success rates were evaluated. It was concluded that this procedure was a successful procedure for dogs and the transdiaphragmatic approach was more useful. In conclusion, thoracoscopic partial pericardiectomy was determined to be easy to apply and more advantageous than open thoracotomy operations.

“…Three biopsy techniques were used. The TP samples were collected by twisting the forceps 90° clockwise while gently pulling away from the liver lobe until the tissue sample released from the liver 9,15 . The T samples were collected by twisting the forceps 180° back and forth until the tissue sample released from the liver.…”

ObjectiveTo determine whether 3 and 5 mm laparoscopic cup biopsy forceps provide samples of equivalent diagnostic quality in cats.Study designExperimental study.AnimalsTwelve colony cats undergoing a concurrent nutrition study.MethodsTwo biopsy forceps (3 and 5 mm) and three biopsy techniques (twist, pull, and twist + pull) were used to collect 68 laparoscopic liver samples. Biopsies were performed consecutively with the 3 and 5 mm biopsy sites adjacent to each other. Data analyzed included the number of portal triads and hepatic lobules, tissue crush and fragmentation, overall sample area (mm2), sample weight, and agreement regarding morphologic diagnosis.ResultsThe 5 mm forceps provided more hepatic lobules, portal triads, and a larger tissue weight and histologic area (mm2) (p < .01). The twist and pull techniques provide more hepatic lobules and portal triads compared to the twist + pull technique while the twist + pull technique resulted in greater tissue crush compared to the twist technique (p = .0097). There was good agreement for morphological diagnosis between the 3 and 5 mm samples using the twist + pull technique but not for the twist or pull techniques.ConclusionLiver samples can be safely collected with 3 or 5 mm laparoscopic biopsy forceps and provide sufficient tissue for histopathology analysis in cats, with minimal artifact. The diagnostic accuracy of 3 mm samples remains unknown.Clinical significanceAlthough 3 mm laparoscopic cup biopsy forceps provided samples of sufficient diagnostic quality for histopathologic interpretation in cats, further studies are required to assess their diagnostic accuracy.

Effects of two alveolar recruitment maneuvers in an “open-lung” approach during laparoscopy in dogs

et al. 2022

ObjectivesThe aim of this study was to compare the effects of a sustained inflation alveolar recruiting maneuver (ARM) followed by 5 cmH2O of PEEP and a stepwise ARM, in dogs undergoing laparoscopic surgery.Materials and methodsTwenty adult dogs were enrolled in this prospective randomized clinical study. Dogs were premedicated with methadone intramuscularly (IM); anesthesia was induced with propofol intravenously (IV) and maintained with inhaled isoflurane in pure oxygen. The baseline ventilatory setting (BVS) was as follows: tidal volume of 15 mL/kg, inspiratory pause of 25%, inspiratory to expiratory ratio of 1:2, and the respiratory rate to maintain the end-tidal carbon dioxide between 45 and 55 mmHg. 10 min after pneumoperitoneum, randomly, 10 dogs underwent sustained inflation ARM followed by 5 cmH2O of PEEP (ARMi), while 10 dogs underwent a stepwise recruitment maneuver followed by the setting of the “best PEEP” (ARMc). Gas exchange, respiratory system mechanics, and hemodynamic were evaluated before the pneumoperitoneum induction (BASE), 10 min after the pneumoperitoneum (PP), 10 min after the recruitment (ARM), and 10 min after the pneumoperitoneum resolution (PostPP). Statistical analysis was performed with the ANOVA test (p < 0.05).ResultsStatic compliance decreased in both groups at PP (ARMc = 1.35 ± 0.21; ARMi = 1.16 ± 0.26 mL/cmH2O/kg) compared to BASE (ARMc = 1.78 ± 0.60; ARMi = 1.66 ± 0.66 mL/cmH2O/kg) and at ARM (ARMc = 1.71 ± 0.41; ARMi = 1.44 ± 0.84 mL/cmH2O/kg) and PostPP (ARMc = 1.75 ± 0.45; ARMi = 1.89 ± 0.59 mL/cmH2O/kg), and it was higher compared to PP and similar to BASE. The PaO2/FiO2, in both groups, was higher at ARM (ARMc = 455.11 ± 85.90; ARMi = 505.40 ± 31.70) and PostPP (ARMc = 521.30 ± 66.20; ARMi = 450.90 ± 70.60) compared to PP (ARMc = 369.53 ± 49.31; ARMi = 394.32 ± 37.72).Conclusion and clinical relevanceThe two ARMs improve lung function in dogs undergoing laparoscopic surgery similarly. Application of PEEP at the end of the ARMs prolonged the effects of the open-lung strategy.
