The mouse as a model to study adhesion formation following endoscopic surgery: a preliminary report.

Our aim was to investigate the feasibility of a mouse model to study adhesion formation following endoscopic surgery. Following preliminary studies to establish anaesthesia and pneumoperitoneum pressure, a prospective randomized study was carried out to investigate the effect of CO2 pneumoperitoneum on postoperative adhesions. In group I (control group), the duration of pneumoperitoneum was shorter than 5 min.

Fetal membrane closure techniques after hysteroamniotomy in the midgestational rabbit model.

Objective: We studied closure techniques for amniotic access in midgestational rabbits.

Study Design: Twenty-eight rabbits with a total of 313 amniotic sacs were used for this study. In each animal a 1 cm hysteroamniotomy was made in two amniotic sacs at 22 days' gestation (term = 32).

Fetoscopy-guided fetal endoscopy in a sheep model.

Video-endoscopic surgical treatment of the fetus may, in the future, become an alternative to open fetal operation. Six 95-day-old fetal lambs were examined through intrauterine endoscopy using amnioinfusion and specially designed balloon-tipped cannulas. The fetuses were monitored endoscopically for oxygen saturation, heart rate and temperature throughout the procedure.
