Laparoscopic cholecystectomy can be performed successfully for uncomplicated gall bladder disease in dogs after careful case selection. The surgeon considering laparoscopic cholecystectomy should be familiar with a variety of methods for cystic duct dissection and ligation to avoid difficulties during the procedure.
Evidence before this study: Acute appendicitis is the most common general surgical emergency in children. Its diagnosis remains challenging and children presenting with acute right iliac fossa (RIF) pain may be admitted for clinical observation or undergo normal appendicectomy (removal of a histologically normal appendix). A search for external validation studies of risk prediction models for acute appendicitis in children was performed on MEDLINE and Web of Science on 12 January 2017 using the search terms ["appendicitis" OR "appendectomy" OR "appendicectomy"] AND ["score" OR "model" OR "nomogram" OR "scoring"]. Studies validating prediction models aimed at differentiating acute appendicitis from all other causes of RIF pain were included. No date restrictions were applied. Validation studies were most commonly performed for the Alvarado, Appendicitis Inflammatory Response Score (AIRS), and Paediatric Appendicitis Score (PAS) models. Most validation studies were based on retrospective, single centre, or small cohorts, and findings regarding model performance were inconsistent. There was no high quality evidence to guide selection of the optimum model and threshold cutoff for identification of low-risk children in the UK and Ireland. Added value of this study: Most children admitted to hospital with RIF pain do not undergo surgery. When children do undergo appendicectomy, removal of a normal appendix (normal appendicectomy) is common, occurring in around 1 in 6 children. The Shera score is able to identify a large low-risk group of children who present with acute RIF pain but do not have acute appendicitis (specificity 44%). This low-risk group has an overall 1 in 30 risk of acute appendicitis and a 1 in 270 risk of perforated appendicitis. The Shera score is unable to achieve a sufficiently high positive predictive value to select a high-risk group who should proceed directly to surgery. Current diagnostic performance of ultrasound is also too poor to select children for surgery. Implications of all the available evidence: Routine pre-operative risk scoring could inform shared decision making by doctors, children, and parents by supporting safe selection of lowrisk patients for ambulatory management, reducing unnecessary admissions and normal appendicectomy. Hospitals should ensure seven-day-a-week availability of ultrasound for medium and high-risk patients. Ultrasound should be performed by operators trained to assess for acute appendicitis in children. For children in whom diagnostic uncertainty remains following ultrasound, magnetic resonance imaging (MRI) or low-dose computed tomography (CT) are second-line investigations.
Objective: To evaluate and compare outcome in dogs that underwent singleincision laparoscopic-assisted intestinal surgery (SILAIS) and open laparotomy (OL) for simple foreign body removal. Study design: Retrospective study. Animals: Twenty-eight client-owned dogs that underwent SILAIS (n = 13) or OL (n = 15). Methods: Foreign body removal via SILAIS was performed with a commercially available single-port device. After laparoscopic evaluation, a wound retraction device (WRD) was inserted. The small intestine was extracorporeally explored, and foreign body removal was performed. The surgeon's hand was inserted through the WRD to palpate portions of the gastrointestinal tract not able to be extracorporeally evaluated. Open laparotomy with foreign body removal was performed via a ventral midline approach. Medical records were retrospectively reviewed, and perioperative data were collected. Follow-up data were collected with a standardized questionnaire with the referring veterinarian and/or owner via telephone interview. Results: No postoperative complications were encountered in either the SILAIS or the OL group, and all dogs were successfully discharged from the hospital. Conversion from SILAIS to OL occurred in 3/13 cases. There was no significant difference in duration of hospitalization, duration of time to recovery, or surgical time between surgical approaches (SILAIS vs OL). Conclusion: Single-incision laparoscopic-assisted intestinal surgery for foreign body removal was not significantly different from OL in a variety of outcome measures in this cohort of dogs. Diagnostic imaging including ultrasonography or computed tomography may improve appropriate case selection for SILAIS for simple foreign body removal. Clinical significance: Single-incision laparoscopic-assisted intestinal surgery offers a minimally invasive technique for simple small intestinal foreign body removal. Additional study is required to compare SILAIS with OL.Results of this study were presented in part at
LAG was an effective procedure for prevention of GDV and was associated with high client satisfaction in this cohort of dogs. A moderate rate of postoperative wound complications occurred that were minor and self-limiting in nature.
OBJECTIVE To determine whether simulator-assessed laparoscopic skills of veterinary students were associated with training level and prior experience performing nonlaparoscopic veterinary surgery and other activities requiring hand-eye coordination and manual dexterity. DESIGN Experiment. SAMPLE 145 students without any prior laparoscopic surgical or fundamentals of laparoscopic surgery (FLS) simulator experience in years 1 (n = 39), 2 (34), 3 (39), and 4 (33) at a veterinary college. PROCEDURES A questionnaire was used to collect data from participants regarding experience performing veterinary surgery, playing video games, and participating in other activities. Participants performed a peg transfer, pattern cutting, and ligature loop-placement task on an FLS simulator, and FLS scores were assigned by an observer. Scores were compared among academic years, and correlations between amounts of veterinary surgical experience and FLS scores were assessed. A general linear model was used to identify predictors of FLS scores. RESULTS Participants were predominantly female (75%), right-hand dominant (92%), and between 20 and 29 years of age (98%). No significant differences were identified among academic years in FLS scores for individual tasks or total FLS score. Scores were not significantly associated with prior surgical or video game experience. Participants reporting no handicraft experience had significantly lower total FLS scores and FLS scores for task 2 than did participants reporting a lot of handicraft experience. CONCLUSIONS AND CLINICAL RELEVANCE Prior veterinary surgical and video game experience had no influence on FLS scores in this group of veterinary students, suggesting that proficiency of veterinary students in FLS may require specific training.
