Results suggested that laparoscopic ovariectomy with 2 instrument cannulas, rather than with 1, resulted in shorter surgical times without increasing severity of postoperative pain.

Canine transitional cell carcinoma (TCC) of the bladder has historically been treated with a combination of chemotherapy, cyclooxygenase inhibitors and radiation therapy. While surgery has been used to treat TCC of the bladder, its efficacy has yet to be established. Thirty-seven client owned dogs that underwent partial cystectomy +/- various nonsurgical treatments for TCC were retrospectively evaluated. The overall median progression-free interval (PFI) was 235 days and the median survival time (ST) was 348 days. Prognostic factors identified on univariate analysis significant for ST were age, tumor location, full thickness excision and frequency of piroxicam administration. Prognostic factors significant for PFI were full thickness excision and frequency of piroxicam administration. The median ST with partial cystectomy and daily piroxicam therapy, with or without chemotherapy, was 772 days. Dogs with non-trigonal bladder TCC treated with full thickness partial cystectomy and daily piroxicam (+/- chemotherapy) may have improved outcome compared to dogs treated with medical therapy.

CB and PTCE are associated with similar short-term and intermediate-term survival. PTCE is a minimally invasive alternative to CB via celiotomy. However, CB allows concurrent abdominal procedures requiring the same approach.

Retroperitoneal abscesses, although uncommon, are clinically important. Medical records of seven dogs with naturally occurring retroperitoneal infections from 1999 to 2011 were reviewed to document historical, examination, clinicopathologic, imaging, and surgical findings; etiologic agents; and outcome. Middle-aged sporting dogs were most commonly affected. Dogs were febrile with evidence of either abdominal or lumbar pain. Although traditional radiography can aid in diagnosis, ultrasound appeared to be a more sensitive indicator of disease within the retroperitoneal space. Numerous bacteria were isolated from the abscesses, with anaerobic and facultative anaerobic bacteria being the most commonly isolated. Etiology was largely unknown, but migrating plant material was often suspected. Resolution of the infection required surgical intervention as well as prolonged antibiotic therapy. Although recurrence is possible, outcome can be favorable with no long-term sequela.

All tested techniques seemed safe except the vessel sealant device since it did not consistently seal every biopsy and leaked at pressures <20 cmH2 O.
