AI Article Synopsis
- The study compared construction time and leak testing between hand-sewn and skin staple techniques for intestinal surgeries in cats.
- Hand-sewn anastomoses took significantly longer to complete compared to skin staple anastomoses, but both methods showed no significant difference in intraluminal pressure.
- While skin staple enterotomies were much faster than hand-sewn enterotomies, they had lower intraluminal pressure and higher rates of leakage, suggesting that skin staple enterotomies are less reliable than hand-sewn methods.
Article Abstract
Objective: To compare time to construct completion and leak testing between hand-sewn and skin staple anastomoses and enterotomies in cats.
Study Design: Ex vivo, randomized study.
Animals: Fresh feline cadavers (n = 20).
Methods: Jejunal segments (8 cm) were harvested and tested on the same day as euthanasia. From each cadaver, one segment was randomly assigned to control (C), hand-sewn enterotomy (HSE), and skin staple enterotomy (SSE) groups, and two segments were randomly assigned to hand-sewn anastomosis (HSA) and skin staple anastomosis (SSA) groups. Construct completion time, initial leak pressure (ILP), and maximum intraluminal pressure were compared. Leakage location was reported.
Results: Mean time (s) ± SD was longer (p < .001) for HSA (317.0 ± 50.9) than SSA (160.8 ± 13.1) and for HSE (172.0 ± 36.5) than SSE (20.3 ± 5.0). ILP (mean ± SD) for C (600.0 mmHg ±0.0) was higher (p < .001) than all constructs. ILP (mean ± SD) for SSA (124.2 mmHg ±83.7) was not different (p = .49) than HSA (86.1 ± 51.9), but HSE (200.3 ± 114.7) was higher (p < .001) than SSE (32.2 ± 39.7). Immediate leakage from the center of enterotomy closure was observed in 7/20 SSE.
Conclusions: HSA construct completion took twice as long as SSA with no difference in intraluminal pressures. Although HSE construct completion took 8x as long as SSE, HSE had higher intraluminal pressures.
Clinical Significance: In cats, SSA may be an alternative to HSA for intestinal anastomosis, but SSE is not recommended as an alternative to HSE for intestinal enterotomy closure.

BACKGROUND Perineal injuries affecting the scrotum and penis are rare in pediatric patients, owing to the protective anatomy of the male genitalia. However, when such injuries do occur, timely surgical intervention is crucial. This kind of damage might not be life-threatening but could cause functional disorders and have a huge impact on the patients' psychological condition if not treated appropriately, especially as they enter puberty.
