“…The application of laparoscopy, minimally invasive technique, along with its advantages and superiorities, has become an alternative approach to conventional surgery in small animal veterinary medicine [1-3]. Laparoscopy created huge changes in the field of surgery from large incisions in open surgeries to very small incisions.…”

BackgroundSingle incision laparoscopic surgery (SILS) is a newly growing technique to replace a more invasive conventional multiple portal laparoscopic surgery. The objective of this study was to compare single (SILS) with three portal (Conventional) laparoscopic splenectomy in dogs. Mongrel dogs (n = 18), weighting 15 ± 3 kg, were selected for this study (n = 12 SILS; n = 6 conventional). The area from xiphoid to pubis was prepared under aseptic conditions in dorsal recumbency with the head down and tilted 30 degree in the right lateral position. Pneumoperitoneum was established by CO2 using an automatic high flow pressure until achieving 12 mm Hg. Instrumentation used consisted of curved flexible-tip 5 mm Maryland forceps and ultracision harmonic scalpel for sealing and cutting of the vessels and splenic attachments.ResultsAll dogs recovered uneventfully. The splenectomy procedure using SILS and conventional methods were significantly different in the respective operative time (29.1 ± 1.65 vs. 42.0 + 2.69 min) and the length of the surgical scar (51.6 ± 1.34 mm vs. 72.0 ± 1.63 mm; P < 0.001). There were no post-operative wound complication including inflammation, infection, hernia formation and dehiscence up to one month after surgery. Meanwhile, the conversion to open surgery or application of additional portals was not required in both approaches.ConclusionThis study demonstrated that SILS is a safe and feasible operation and could be used as an alternative approach to three portal (Conventional) for splenectomy in dog.

“…Although some authors have mentioned that peritoneal tenting is unlikely in animals with a tightly adherent peritoneum, such as dogs and goats, 19 we are unaware of any study that has validated this conjecture. For this study, the distance that the VN travelled between the subcutaneous tissue and the peritoneal perforation, which was based on 2 surrogate markers of perforation, was defined as the VNPD.…”

“…5,[16][17][18] These complications include injury to the abdominal or thoracic wall vasculature, injury to intra-abdominal or intrathoracic vessels, penetration of solid organs or hollow viscera, subcutaneous emphysema, and gas embolism. 19,20 Pneumothorax can occur as a result of incorrect intercostal VN placement, 16 and inadvertent positioning of the VN tip between the abdominal musculature and the peritoneum can lead to preperitoneal gas insufflation. 21 Another complication reported with VN insertion is peritoneal tenting, 19 which is also known as the curtain effect.…”

“…20 This phenomenon occurs when the peritoneum is displaced under the pressure of the inner stylet before the sharp cannula cuts through it; as a result, the peritoneum is not penetrated by the VN, and the distal extremity of the needle does not communicate with the peritoneal cavity. 19,20 The ease of penetration and the pressure exerted on the abdominal wall of a given VN depend on the spring rate, the forces required to retract the stylet, the bevel design, and the sharpness. In one study, 11 differences in the spring rate and on the forces were found among 13 commercially available VN.…”

Influence of 2 Veress needles and 4 insertion sites on Veress needle penetration depth: A comparative study in cadaveric dogs

ObjectiveTo evaluate the penetration depth (VNPD) of 2 disposable Veress needles (VN) at 4 insertion sites in the abdomen.Study designDescriptive study.Sample populationCanine cadavers (n = 22, 6 for confirmation of the test methods and 16 for the comparative study).MethodsTwo disposable VN (VN A and VN B) were inserted at 4 sites (9th intercostal space [ICS] and preumbilical, paraumbilical, and subumbilical sites) in dorsally recumbent dogs by using a hand‐cranked jig. The VNPD was measured as the distance traveled by the VN between the subcutaneous tissue and the perforation of the peritoneum on the basis of audible clicks and visible feedback from the VN. The effects of the VN type and insertion site on the VNPD were analyzed by using a linear mixed‐effects model.ResultsVNPD varied between insertion sites (P = .01) and VN (P < .01). The VNPD was less at the 9th ICS than at the preumbilical, paraumbilical, and subumbilical sites. The maximal magnitude of change was 7.4 mm. Veress needle B (with a low spring rate, lower forces, and a back‐cut bevel design) penetrated farther than VN A (with a high spring rate, high forces, and a lancet‐type bevel) at 3 of 4 insertion sites. The maximal magnitude of change was 6.8 mm.ConclusionVeress needle penetration depth varied between VN designs but was the least at the 9th ICS in canine cadavers.Clinical significanceInsertion of a VN at the 9th ICS is recommended to minimize its penetration into the abdomen. Associations between VNPD and mechanical factors, such as the sharpness and spring rate of VN, warrant additional research.
