T he limitations of laparoscopic surgery include the loss of tactile feedback and the inability to palpate deep parenchymal lesions, which may impair intraoperative surgical assessment. In humans, the increasing use of laparoscopic ultrasound (LUS

Many challenges are encountered when performing laparoscopic versus traditional open surgery, including the fulcrum effect and the loss of stereoscopic vision, tactile sensation, and depth perception. 1 Therefore, the advanced skills necessary
Laparoscopic spay procedures are becoming increasingly common in veterinary practice, and laparoscopic ovariectomy is one of the most commonly performed minimally invasive companion animal surgeries in the United States. 1 The popularity of these
Abstract
Objective—To evaluate the use of ultrasonography to detect morphologic changes in the pylorus during pyloroplasty performed laparoscopically or via conventional abdominal surgery in dogs.
Animals—10 healthy mixed-breed dogs.
Procedure—Laparoscopic ultrasonography of the pylorus was performed in 5 dogs during laparoscopic pyloroplasty (LP), and ultrasonography of the pylorus was performed in 5 dogs during pyloroplasty via conventional abdominal surgery (CAP group). Appearance and dimensions of the pyloric sphincter were evaluated by use of a 7.5-MHz flexible laparoscopic linear-transducer probe.
Results—Mean ± SD duration of the ultrasonographic procedure was 11 ± 3.04 minutes (range, 6 to 18 minutes). In the CAP group, cross-sectional views of the pylorus revealed significant differences between the overall transverse external diameter, overall craniocaudal external diameter, and transverse diameter of the pyloric lumen. After surgery, the pyloric area was significantly increased. Longitudinal views of the pylorus revealed that width of the pyloric ring was significantly less after surgery. Transverse views of the pylorus for the LP group revealed a significant increase in the transverse diameter and craniocaudal diameter of the pyloric lumen after LP. The pyloric area was also significantly increased after surgery. Longitudinal views of the pylorus revealed that width of the pyloric ring was significantly less after surgery. Transverse diameter of the pyloric lumen was significantly increased after LP.
Conclusions and Clinical Relevance—Analysis of results of this study suggests that ultrasonography is useful for detecting relevant morphologic changes in the pyloric sphincter after pyloroplasty. (Am J Vet Res 2003;64:1099–1104)
Laparoscopic approaches for ovariectomy and ovariohysterectomy have been described in multiple species and are favored over open laparotomy techniques. 1–3 Laparoscopic surgical techniques are gaining popularity over traditional open surgical
in the United States. 1 Applicable surgical approaches include laparoscopy with a single 2–5 or multiple access ports, 5 open midline laparotomy, and lateral flank laparotomy. 6 Studies documenting advantages for patients undergoing laparoscopic

Laparoscopic surgery has become well established as a diagnostic and treatment modality in veterinary medicine. Benefits of this minimally invasive technology include high diagnostic accuracy and shorter recovery times and a decreased requirement
of laparoscopy over laparotomy in human and veterinary medicine have been described. 13–15 Compared with laparotomy, laparoscopic techniques are minimally invasive and associated with less tissue trauma, a lower risk for dehiscence, less pain, and a
