Trans-Endoscopic ultrasonography of the oesophagus and gastrointestinal tract in dogs and cats: Pathological findings
Full text linkThis study aimed to report our experience in clinical application of Trans-Endoscopic Ultrasound (TEUS) to the gastrointestinal tract. TEUS was performed on 9 dogs and 2 cats, using a 2.6 mm 12-20 MHz-mini-probe, introduced through the operative channel of a 9.7-mm-flexible endoscope. The ultrasonographic probe had 360° vision around the transducer (radial probe). TEUS examinations were well tolerated by all animals. Experience and practice reduced the time required for examination (on the average 45 min) for a complete endoscopic and TEUS examination. Out of 11 animals, two had esophageal stenosis, two showed gastric carcinoma, two had duodenitis, two exhibited rectal polyposis, one had lymphoma and ileocecal intussusception, one had rectal adenocarcinoma and one showed
chronic gastritis. Thus, combination of ultrasound and endoscopy allowed intrinsic limits of both techniques to be overcome, enabling a complete diagnostic protocol
and/or a minimally invasive surgical procedure. In malignant neoplasia, TEUS provided prognostic information for TNM grading
Deep Vegetal Foreign Bodies in Cats: A Retrospective Study of 10 Cases
No full textThe aim of this study was to describe the anatomic locations and treatments available for deeply located vegetal foreign bodies in cats. Ten cases of migrating vegetal foreign bodies (vFBs) requiring surgical removal are reported. The diagnoses of vFBs in the thoracic cavity (4/10), retroperitoneal space (2/10), and paratracheal region (1/10) were obtained by ultrasound examination; however, in the perineum or penile urethra (2/10) and peritoneum (1/10), the vFBs were found during surgery. Intraoperative ultrasound guidance helped remove vFBs from the retroperitoneal space and paratracheal tissues. Clinical signs resolved in 8 out of 10 cases, 1 out of 10 cases had recurrent draining fistula, and 1 out of 10 was euthanized for ethical reasons. The intrathoracic was the most common location in the present study, followed by retroperitoneal space and urethra/perineum. Ultrasound guidance was essential for the diagnosis and/or treatment of vFBs located in the thoracic, retroperitoneal, and cervical regions
Laparotomy‐assisted endoscopic removal of gastrointestinal foreign bodies: Evaluation of this technique and postoperative recovery in dogs and cats
Full text linkObjective: To compare the outcome of the laparotomy-assisted endoscopic removal (LAER) of gastrointestinal foreign bodies (FBs) with traditional enterotomy, and to determine which factors affected the ability to remove FBs. Study design: Retrospective observational study. Sample population: Dogs and cats (n = 81) with gastrointestinal FBs. Methods: Dogs and cats were divided into Group 1 (LAER, n = 40) and Group 2 (Enterotomy, n = 41). The localization and characteristics of the FBs (sharp or blunt; discrete or linear; single or multiple) were evaluated statistically to identify the factors that affected the ability of LAER to remove, partially or completely, the FBs (chi(2) test). The length of the postoperative stay, postoperative analgesia, and resumption of spontaneous feeding were compared between groups (Mann-Whitney U-test). Short-term follow up (14 days) was recorded. Results: Laparotomy-assisted endoscopic removal allowed complete or partial removal of FBs in 35/40 dogs and cats, regardless of the characteristics or the localization of the FBs. The presence of intestinal wall damage (p = .043) was associated with the conversion to an enterotomy. Group 1 required a shorter postoperative hospital stay (p = .006), less need for analgesia (p < .001), and experienced a faster resumption of spontaneous feeding (p = .012), and similar complication rate to Group 2. Conclusion: Laparotomy-assisted endoscopic removal resulted in a faster postoperative recovery when compared with an enterotomy. The FBs' characteristics or localization did not affect the efficacy of the technique to remove FBs. Clinical significance: Laparotomy-assisted endoscopic removal allows the removal of a variety of FBs, avoiding intestinal incision and resulting in a fast postoperative recovery
Aloe barbadensis miller versus silver sulfadiazine creams for wound healing by secondary intention in dogs and cats: A randomized controlled study
No full textThe objective of this study was to compare the effectiveness of the topical application of Aloe barbadensis Miller (juice and fresh gel) to skin wounds, in dogs and cats, with that of topically applied silver sulfadiazine cream. The sample included 16 patients with cutaneous wounds (13 dogs and three cats) that were divided into three groups. Aloe vera âjuiceâ and âfresh gelâ were applied for groups I and II, respectively, while silver sulfadiazine was applied for the control group III. In order to evaluate the healing of wounds, the following parameters were taken into consideration: the percentage of wound shrinkage, the healing time and the macroscopic appearance of the scarring process. The interpretation of the data relating to the percentage of wound shrinkage showed a faster rate for groups I and II compared to that of group III. However, the wound shrinkage rates between âjuiceâ and âfresh gelâ protocols were not significantly different. Aloe vera was more effective than silver sulfadiazine, in accelerating wound shrinkage, reducing healing time and decreasing the severity of the associated injuries
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Use of a polypropylene prosthetic mesh to support traditional perineal herniorrhaphy in dogs
Full text linkScopo del progetto di dottorato è stato quello di mettere a punto l’utilizzo di una tecnica alternativa, rispetto a quelle riportate in letteratura, per la risoluzione dell’ernia perineale nel cane.
Tale tecnica si propone di risolvere il difetto mediante l’ausilio di una rete protesica in polipropilene
in supporto all’erniorrafia perineale tradizionale, mediante sutura a punti staccati dei muscoli che costituiscono il diaframma pelvico.
Questa procedura risulta meno invasiva per l’animale rispetto alla tecnica che in letteratura viene definita il gold standard, ovvero la trasposizione del muscolo otturatore interno (Shaughnessy and Monnet, 2015), ed altre tecniche traspositive, quali la trasposizione del muscolo semitendinoso (Morello et al., 2015) e del gluteo superficiale (Bellenger & Canfield, 2002), con tempi di recupero postoperatori più rapidi e una gestione più semplice da parte del proprietario, pur mantenendo eccellenti outcomes.
La messa a punto di questa procedura nasce dalla necessità di trovare una tecnica semplice da
eseguire, che determini una chiusura del diaframma pelvico tale da evitare la comparsa di recidive e
minimizzare le complicazioni post-operatorie.
L’intento del progetto è stato di combinare l’erniorrafia perineale tradizionale con l’utilizzo di reti protesiche così da ricostruire il diaframma pelvico con i muscoli deputati a svolgere tale compito e fornire, tramite la rete, un maggiore supporto alla rafia, evitando le trasposizioni muscolari che comporterebbero un intervento più demolitivo e un recupero più lento da parte del paziente.
Sono stati inclusi nello studio 30 cani portatori di ernia perineale, per un totale di 50 ernie, trattati con l’intervento proposto dal progetto. Di ogni caso sono stati raccolti il segnalamento, l’anamnesi, le indagini diagnostiche e i successivi follow up post-operatori considerando le eventuali complicazioni o la comparsa di recidiva dell’ernia.The aim of the PhD's project was to develop the use of an alternative technique, compared to those reported in the literature, for the resolution of perineal hernia in dogs.
This technique aims to solve the defect with the help of a polypropylene prosthetic mesh in support of the traditional perineal herniorrhaphy, by suturing the muscles that make up the pelvic diaphragm with separate stitches.
This procedure is less invasive for the animal than the technique which in the literature is defined as the gold standard, i.e. the transposition of the obturator internus muscle (Shaughnessy and Monnet, 2015), and other transposition techniques, such as transposition of the semitendinosus muscle (Morello et al., 2015) and gluteus superficialis (Bellenger & Canfield, 2002), with faster postoperative recovery times and easier management by the owner, while maintaining excellent outcomes.
The development of this procedure stems from the need to find a simple technique to perform, which determines a closure of the pelvic diaphragm such as to avoid the appearance of recurrences and minimize post-operative complications.
The intent of the project was to combine traditional perineal herniorrhaphy with the use of prosthetic mesh so as to reconstruct the pelvic diaphragm with the muscles assigned to perform this task and provide, through the mesh, greater support to the raffia, avoiding the muscular transpositions which would involve a more demolitive intervention and a slower recovery by the patient.
Thirty dogs with perineal hernia were included in the study, for a total of 50 hernias, treated with the intervention proposed by the project. Reporting, anamnesis, diagnostic investigations and subsequent post-operative follow-ups were collected for each case, considering any complications or the appearance of recurrence of the hernia
