🔍 Key Findings

50 dogs underwent bilateral anal sacculectomy using a modified closed technique.
Intraoperative anal sac perforation occurred in 5 dogs (10%), with no postoperative complications in those dogs.
Postoperative complications (43 dogs with follow-up):

• Grade 1 (e.g., scooting, inappropriate defecation): 14/43 (32%)
• Grade 2 (medical treatment needed): 2/43 (5%)
• Grade 3B (revision surgery): 2/43 (5%)

93% of grade 1 and 100% of grade 2–3B complications resolved by two weeks postop.
Technique highlights: direct duct tracking, no anal sac packing, minimal dissection.

🔍 Key Findings

• PCCLm resulted in significantly fewer postoperative lower urinary tract signs compared to OC (13.0% vs 60.9%, p <.001).
• Incomplete urolith removal was not significantly different between PCCLm and OC (11.4% vs 20%, p = .112).
• PCCLm had significantly shorter anesthesia times than OC when no concurrent procedures were performed (97.5 vs 120 min, p < .001).
• Surgical site infection/inflammation (SSII) rates were low and not significantly different between groups (4.5% PCCLm vs 1.8% OC).
• Dogs undergoing PCCLm were more frequently discharged same-day (84.7% vs 0% in OC), reflecting faster recovery.
• PCCLm had higher intraoperative complication rates (22.1% vs 3.4%), mostly due to incision extension or conversions.
• Time to additional surgery for urolith recurrence was longer in PCCLm dogs (24 vs 11.5 months, p = .004).
• Calcium oxalate uroliths were more prevalent in PCCLm cases, while OC had more struvite or mixed types.
