Folk CA, Buote NJ, Socha DE, Hayes GM. Incidence of residual biologic debris and contamination of reused bipolar vessel sealing devices after ethylene oxide sterilization following splenectomy. Vet Surg 2024. [PMID: 39149916 DOI: 10.1111/vsu.14153] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/07/2024] [Revised: 06/13/2024] [Accepted: 07/29/2024] [Indexed: 08/17/2024]
Abstract
OBJECTIVE The aim of the present study was to quantify the amount of biologic debris present within disposable bipolar vessel sealing devices after each use for canine splenectomies and determine the aerobic bacterial load of the debris following instrument resterilization with ethylene oxide. STUDY DESIGN Prospective observational clinical study. STUDY POPULATION Client-owned dogs (n = 40) presenting to a single specialty hospital for open, routine, or emergency splenectomies. METHODS A total of 16 bipolar vessel sealing devices were randomly assigned to undergo one, two, three, or four splenectomies, manual hand cleanings, and ethylene oxide sterilizations before being dismantled. After final use and sterilization, each handset was agitated in phosphate-buffered saline before disassembly, which was submitted for aerobic culture. Following aseptic disassembly, all biological residue was photo-documented, collected, quantified using a subjective scoring system, and submitted for culture. RESULTS Biologic debris was present within the inner mechanics of all devices, specifically under the blade used for vessel transection. A linear increase in debris was not appreciated amongst devices used once versus devices used multiple times. None of the devices nor any of the biologic debris cultured positive following sterilization with ethylene oxide. CONCLUSION The presence of biologic debris was documented after the initial use of disposable bipolar vessel sealing devices, but no devices or debris yielded positive culture results following ethylene oxide sterilization after splenectomies. CLINICAL SIGNIFICANCE Increased risk of iatrogenic surgical site contamination from reused vessel sealing devices is unlikely when they have been cleaned and sterilized with ethylene oxide after up to four splenectomy surgeries.

Abstract
OBJECTIVE To determine the feasibility of open cholangioscopy using disposable flexible endoscopes in canine cadavers and describe the surgical approach. STUDY DESIGN Ex vivo experimental cadaveric study. SAMPLE POPULATION Eight canine cadavers. METHODS Cadavers ranging from 5.8 to 43.8 kg underwent open transcholecystic cholangioscopy using a disposable flexible endoscope with a 3.8 mm outer diameter and 1.2 mm working channel and the surgical approach was described. The most distal anatomical region of the biliary tree towards the duodenal papilla that was visualized with the endoscope was recorded in each cadaver. A 2.7 mm rigid endoscope and a 1.9 mm flexible endoscope were also trialed and findings recorded. Endoscopic tools were trialed and their usage recorded. RESULTS The disposable flexible endoscope was feasible for visualization of the junction of the common bile duct, cystic duct, and hepatic ducts in all eight dogs. Cholangioscopy using a 2.7 mm rigid endoscope did not provide further distal visualization. The 1.9 mm flexible endoscope was able to traverse down to the level of the major duodenal papilla in a 43.8 kg cadaver. Use of certain endoscopic tools can be considered through the disposable flexible endoscope although fluid instillation was affected. CONCLUSION A 3.8 mm disposable flexible endoscope could be placed through an open transcholecystic approach to provide intraluminal endoscopic evaluation up to the level of the junction of the common bile duct, cystic duct, and hepatic ducts in dogs without cholecystic disease. CLINICAL SIGNIFICANCE Open transcholecystic cholangioscopy with a disposable flexible endoscope could provide a low-cost diagnostic and therapeutic tool in cases of obstructive biliary disease up to the level of the common bile duct.

Kim SH, Lee S. Determining the patency of biliary tracts in dogs with gallbladder mucocele using near-infrared cholangiography with indocyanine green. PLoS One 2024; 19:e0300395. [PMID: 38776340 PMCID: PMC11111041 DOI: 10.1371/journal.pone.0300395] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2023] [Accepted: 02/27/2024] [Indexed: 05/24/2024] Open
Abstract
Cholecystectomy is indicated for gallbladder mucoceles (GBM). Evaluating the patency of the biliary duct and precise biliary tree visualization is crucial for reducing the risk of compromised bile flow after surgery. Therefore, intraoperative cholangiography (IOC) is recommended during cholecystectomy to prevent biliary tract injury. Although indocyanine green (ICG) cholangiography has been extensively reported in human medicine, only one study has been conducted in veterinary medicine. Therefore, this study aimed to demonstrate the use of ICG for IOC to identify fluorescent biliary tract images and determine the patency of the common bile duct during cholecystectomy in dogs. This study comprised 27 dogs, consisting of 17 with gallbladder mucoceles (GBM) and 10 controls, specifically including dogs that had undergone elective cholecystectomy for GBM. ICG injection (0.25 mg/kg) was administered intravenously at least 45 minutes before surgery. During the operation, fluorescent images from cholangiography were displayed on the monitor and obtained in black-and-white mode for the comparison of fluorescence intensity (FI). The FI values of the gallbladders (GBs) and common bile duct (CBD) were measured using FI analyzing software (MGViewer V1.1.1, MetapleBio Inc.). The results demonstrated successful CBD patency identification in all cases. Mobile GBM showed partial gallbladder visibility, whereas immobile GBM showed limited visibility. Additionally, insights into the adequate visualization of the remaining extrahepatic biliary tree anatomy were provided, extending beyond the assessment of CBD patency and gallbladder intensity. Our study demonstrates the potential of fluorescent IOC using intravenous injection of ICG for assessing the patency of the cystic duct and common bile duct during cholecystectomy in patients with GBM, eliminating the need for surgical catheterization and flushing of the biliary ducts. Further research is warranted to investigate and validate the broader applicability of ICG cholangiography in veterinary medicine.

Abstract
OBJECTIVE To compare the effect of three-dimensional (3D) and two-dimensional (2D) laparoscopy on surgical time and intraoperative complications during cholecystectomies in canine cadavers. STUDY DESIGN Experimental prospective study. ANIMALS Twelve canine cadavers. METHODS The laparoscopic cholecystectomies were performed in canine cadavers with four cannulas and with either 2D or 3D cameras by a single surgeon. The following surgical times were recorded: time from insertion of laparoscopic instruments to first endoclip placement, time from first endoclip placement to second endoclip placement, time from second endoclip placement to complete gall bladder dissection, and total surgical time. The cystic duct length distal to the first endoclip, intraoperative complications, and the amount of liver attached to the gall bladder were also recorded. RESULTS Time from the insertion of the instruments to the application of the first endoclip was shorter for the 3D group than for the 2D group (p = .016). Other surgical times were not different between groups. There was no difference in the cystic duct length distal to the first endoclip, intraoperative complications, or the amount of liver attachment. CONCLUSION Three-dimensional laparoscopy shortened the time from insertion of the laparoscopic instruments to placement of the first endoclip. However, total surgical time was not affected by the type of camera in laparoscopic cholecystectomy. CLINICAL SIGNIFICANCE Three-dimensional laparoscopy may be beneficial when performing procedures requiring enhanced spatial orientation. However, this technique did not shorten the total surgical time in this cadaveric study. Further studies in a clinical setting are necessary for the optimization of the future use of 3D laparoscopy.

Abstract
OBJECTIVE To determine the effect of indocyanine green (ICG) dose and timing of administration on near-infrared fluorescence (NIRF) imaging of the normal canine biliary tree. STUDY DESIGN Preclinical prospective study. ANIMALS Eight purpose-bred beagles. METHODS The dogs were randomized to receive two of four intravenous ICG dose (low [L]:0.05 mg/kg or high [H]:0.25 mg/kg)/time (0 and 3 h prior to NIRF) combinations. NIRF images were collected every 10 min for 120 min. Target (cystic duct)-to-background (liver) ratios were calculated for all timepoints and compared. RESULTS ICG cholangiography was successful in all dogs. The contrast ratio was above 1 in the L0 group by 20 min and reached its peak at 100 min. In the H0 group, the ratio was above 1 by 60 min and reached its peak at 90 min. Contrast ratios above 2 (fluorescence twice as bright in the cystic duct compared to the liver) were maintained from 180 to 300 min for L3 and H3 and was achieved after 80 min for L0. CONCLUSION Low dose ICG provided better ratios early after injection compared to the high dose which remained highly concentrated in the liver tissue after injection. Both doses provided excellent visualization of the biliary tree at 3 h post injection, low dose ICG provided better ratios from 3 to 5 h post injection. Based on these results, 0.05 mg/kg of ICG administered at anesthetic premedication, or as early as 3 h prior to laparoscopic surgery should yield optimal fluorescence images. CLINICAL SIGNIFICANCE This study provides guidelines for NIRF cholangiography in clinically normal dogs.

Clinical Outcomes in Dogs Undergoing Cholecystectomy via a Transverse Incision: A Meta-Analysis of 121 Animals Treated between 2011 and 2021. Vet Sci 2023; 10:395. [PMID: 37368781 PMCID: PMC10305690 DOI: 10.3390/vetsci10060395] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2023] [Revised: 06/08/2023] [Accepted: 06/13/2023] [Indexed: 06/29/2023] Open
Abstract
Although many studies have been conducted on the use of median and transverse incisions in various surgeries in the field of human medicine, related studies in veterinary medicine are lacking. This study aimed to present treatment options for dogs requiring cholecystectomy by reporting the pros and cons of 121 cholecystectomies performed via transverse incision at our hospital over 10 years. In most included cases, nonelective cholecystectomy was performed in an unstable emergency situation. The perioperative mortality rate was 23.14%, which was not significantly different from that of cholecystectomy performed via the conventional midline approach. However, the overall operation time (46.24 ± 6.13 min; range 35-65 min) was shortened by securing an adequate surgical field of view. The transverse incision approach facilitates fast and accurate surgery without increasing the fatality rate in small-breed dogs, in whom securing an adequate surgical field of view is difficult. Thus, transverse incision should be actively considered in dogs undergoing cholecystectomy due to emergency conditions, such as bile leakage or biliary tract obstruction, since prolonged anesthesia can be burdensome. This study may improve cholecystectomy outcomes in small-breed dogs with difficult-to-secure surgical fields.

Abstract
OBJECTIVES To describe a standardised subserosal layer dissection technique and evaluate its outcomes in canine laparoscopic cholecystectomy. MATERIALS AND METHODS Medical records of dogs undergoing laparoscopic cholecystectomy using the standardised subserosal layer dissection technique for the treatment of cholecystolithiasis, cholecystitis, and gall bladder mucocele at a single veterinary hospital from January 2015 to September 2021 were extracted. Operative time, subserosal layer dissection achievement rate, open conversion rate, and complication rate were evaluated. RESULTS Thirty-four dogs were included. The most common preoperative diagnosis was cholecystolithiasis (n=29). Operative time was 190 minutes (range: 110 to 330 minutes). Subserosal layer dissection of more than 90% of the gall bladder bed was achieved in 27 (79%) dogs. Conversion to open surgery was required in three (8.8%) dogs. There were no cases of intraoperative bleeding, bile duct injury, or reoperation. CLINICAL SIGNIFICANCE This study showed that laparoscopic cholecystectomy using the standardised subserosal layer dissection technique could be performed successfully in dogs. Future prospective clinical studies are needed to determine safety and effectiveness of this technique compared to standard techniques.

Abstract
The aim of this study is to report outcomes of dogs undergoing cholecystectomy for gall bladder mucocele (GBM) without flushing and catheterization of the common bile duct (CBD). This is a retrospective multicentric study from three veterinary referral hospitals and included 82 dogs diagnosed with GBM. Medical records were reviewed for clinical and histopathological findings. Long-term outcome was assessed with an owner questionnaire. The common bile duct was considered normal (<4 mm), mildly dilated (5−6 mm) and moderately dilated (>7 mm) in 88%, 10% and 2.4% of dogs, respectively. Surgery was uncomplicated in 83% of dogs. Intraoperative complications were recorded in 21% of dogs, with hypotension being the most common, whereas postoperative complications were documented in 20% of dogs, with vomiting/regurgitation being the most common. Ninety-six percent of dogs that underwent cholecystectomy in this study survived to discharge. Follow-up ranged from 142 to 3930 days (median: 549 days). Eighty-five percent of dogs were alive at the time of follow-up. Dogs undergoing cholecystectomy for GBM without catheterization and flushing of the CBD have a favourable prognosis for recovery and quality of life.

Abstract
Background Veterinary minimally invasive surgery (MIS) is rapidly developing, and most surgeons are performing MIS in their clinical practice. The technical skills of presented surgical techniques are increasingly complex. Required training of American College of Veterinary Surgeons (ACVS) surgical residents in soft tissue MIS (laparoscopy/thoracoscopy) are limited to traditional apprentice training. Unfortunately, such training has been found insufficient to create competent MIS surgeons. Aim of the review This review discusses development of MIS training for Doctor of Medicine (M.D.) residents in context of veterinary applicability and investigates comparative evidence for how to best train veterinary residents in soft tissue MIS. Conclusions A structured curriculum, with validated tasks and clear training goals have been found imperative for training success. Such a curriculum includes both didactic sessions and manual skills training, with video tutorials and reading material to inform and motivate the residents. Implications of key findings ACVS residents and diplomates may benefit if a MIS curriculum was developed and made available to all training programs.

Abstract
Veterinary resident training in minimally invasive surgery is currently inconsistent and depends on innate psychomotor skills. Simulation training has been shown to effectively increase basic skills, but demonstration of simulation training effects on advanced skills in the operating room is sparse. We aimed to determine if simulation-trained novice surgeons were able to perform laparoscopic suture ligation in live dogs. Three novice laparoscopic surgeons underwent a 12-session simulation training program with subsequent laparoscopic skills testing to demonstrate competency. The median skills scores of trainees and of one experienced surgeon were 417 and 472, respectively. Eighteen healthy client-owned (shelter) dogs were operated on by four surgeons: one experienced American College of Veterinary Surgeons (ACVS) diplomate, two novice ACVS residents, and one novice ACVS diplomate. Laparoscopic ovariectomy was performed with suture ligation of the ovarian pedicles. Successful surgery was defined as no evidence of ovarian vessel bleeding after transection of the pedicles. Simulation-trained novices performed successful suture-ligated ovariectomies in 11/13 dogs (85%), and the experienced surgeon in 5/5 (100%) dogs. Median total ligation time was 30 minutes (range: 17-57), which was not different among surgeons (p = .118). Median total surgery time was 105 minutes (range: 69-156) for novices and 89 minutes (range: 65-99) for the experienced surgeon (p = .038). Extensive simulation training including suturing may contribute toward surgery residents being able to perform complex laparoscopic procedures. These results need to be confirmed in larger numbers of trainees.

Abstract
OBJECTIVE To describe a laparoscopic approach for performing intraoperative cholangiography (IOC) and bile duct flushing (BDF) during laparoscopic cholecystectomy (LC) in dogs. To investigate the clinical outcomes of dogs undergoing these procedures for the treatment of benign gallbladder disease, ie gallbladder mucocele (GM) or cholecystitis. STUDY DESIGN Retrospective study. ANIMALS Forty-seven client-owned dogs. METHODS Medical records of client-owned dogs with benign gallbladder diseases that underwent IOC and BDF during LC between September 2016 and December 2019 were reviewed. Of these dogs, only dogs with GM or cholecystitis were included in the study. The fundus dissection first method was used for LC. Intraoperative cholangiography and BDF procedures were performed laparoscopically using a catheter inserted into the cystic duct following dissection within the subserosal layer of the gallbladder. Videos recorded during each procedure were reviewed, and data on procedure duration, completion, outcome, and technical approach were recorded. RESULTS Forty-seven dogs were included in the study. The median procedure time for BDF and IOC was 4 min (range, 2-48 min), and no intraoperative or postoperative complications occurred. CONCLUSION During LC, BDF and IOC were performed safely and successfully. Intraoperative cholangiography identified obstructions and strictures in the common bile duct that were not detected using BDF alone. CLINICAL SIGNIFICANCE Our findings suggest that BDF and IOC are both safe and time effective and should be considered for routine use by surgeons during LC.

Abstract
BACKGROUND Gallbladder mucocele (GBM) is a common biliary disorder in dogs. Limited information is available on the coagulation status of dogs with GBM. HYPOTHESIS/OBJECTIVES To determine patterns of coagulation alterations in dogs with GBM and correlate them with clinicopathologic abnormalities and ultrasonographic findings of disease severity. ANIMALS Twenty-three dogs with GBM identified on ultrasound examination were prospectively enrolled. METHODS At the time of GBM identification, blood and urine were collected for CBC, serum biochemical panel, urinalysis, prothrombin time, activated partial thromboplastin time (aPTT), factor VIII, protein C (PC), von Willebrand's factor (vWF), antithrombin activity, fibrinogen, D-dimers, and thromboelastrography (TEG). Gallbladder mucoceles were classified into ultrasound types 1 to 5. Medical records were reviewed for clinical presentation, underlying conditions and to determine if systemic inflammatory response syndrome (SIRS) was present. RESULTS Based on TEG parameters, maximal amplitude, and G, 19/23 (83%) of dogs with GBM had evaluations consistent with hypercoagulability. On plasma-based coagulation testing, dogs with GBM had increased total PC activity (20/23, 87%), fibrinogen (9/23, 39%), platelet count (9/23, 39%), and D-dimers (6/15, 40%) as well as prolongations in aPTT (9/22, 41%) and low vWF activity (5/21, 24%). No correlation was found between TEG G value and any coagulation or clinical pathology variables, ultrasound stage of GBM or disease severity as assessed by the presence of SIRS. CONCLUSIONS AND CLINICAL IMPORTANCE Dogs with ultrasonographically identified GBM have changes in whole blood kaolin-activated TEG supporting a hypercoagulable state although traditional plasma-based coagulation testing suggests that a complex state of hemostasis exists.

Maurin MP, Mullins RA, Singh A, Mayhew PD. A systematic review of complications related to laparoscopic and laparoscopic-assisted procedures in dogs. Vet Surg 2020; 49 Suppl 1:O5-O14. [PMID: 32333685 DOI: 10.1111/vsu.13419] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2019] [Revised: 01/14/2020] [Accepted: 02/20/2020] [Indexed: 12/14/2022]
Abstract
OBJECTIVE To evaluate and report the quality of the scientific literature reporting complications associated with laparoscopic and laparoscopic-assisted procedures in client-owned or healthy research dogs and to report and illustrate laparoscopic complications related to individual organ systems. STUDY DESIGN Systematic review. ANIMALS Client-owned or healthy research dogs. METHODS A literature review was performed by using PubMed and CAB abstracts for English-language studies providing descriptions of complications related to laparoscopic and laparoscopic-assisted procedures in dogs. Study selection used PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) guidelines. Quality assessment was performed by using a MINORS (Methodological Items for Non-Randomized Studies) scoring system and a grading scale of level of evidence. Descriptive statistics were used. RESULTS In total, 741 manuscripts were identified, with 64 manuscripts eligible for data extraction and quality assessment. The most represented organ system was the female genital tract, represented by 22 (34.4%) studies. The most commonly reported intraoperative and postoperative complications were related to abdominal entry and portal incisions, respectively. In 53 of 54 non-randomized studies, high risk of bias was found. Forty-eight (75%) studies provided level III or IV evidence. CONCLUSION This report provides an updated review of complications related to laparoscopic and laparoscopic-assisted procedures in dogs, classified by organ system. The overall quality of evidence was low, limiting direct comparison of complication rates between studies. CLINICAL SIGNIFICANCE There is a need for implementation of standardized criteria for defining complications, study time frames and greater numbers of high quality prospective randomized trials in veterinary laparoscopy to permit comparison of complication and conversion rates between published studies and across organ systems.

[PMID: 31389068 DOI: 10.1111/vsu.13289] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2019] [Revised: 05/26/2019] [Accepted: 05/30/2019] [Indexed: 12/23/2022]
Abstract
OBJECTIVE To evaluate the outcome of laparoscopic cholecystectomy performed with a single port access system (SPAS) in dogs. STUDY DESIGN Retrospective study. ANIMALS Fifteen client-owned dogs with nonobstructive gallbladder disease. METHODS Medical records were reviewed for signalment, clinical signs, diagnostic imaging, surgical findings, and outcome until suture removal. RESULTS The SPAS was placed 1 cm caudal to the umbilicus. The procedure was completed with the SPAS alone in two cases. An additional cannula was added in 12 cases. In the last 10 cases, the additional cannula was placed at the beginning of the procedure. Dissection began at the cystic duct in 11 dogs (73%). In three cases (20%), the SPAS procedure was converted to a laparotomy; two of these conversions were elective, and one was emergent. The risk of conversion was affected by the experience of the surgeon (odds ratio = 0.53; P = .0105), and the rate of conversion was reduced when a cannula was added at the beginning of the procedure (P = .022). Fourteen dogs were discharged from the hospital. One dog died after being discharged due to severe cholangiohepatitis, and another dog died due to leakage of a gastrostomy tube. CONCLUSIONS The use of SPAS for cholecystectomy in dogs has an acceptable outcome. The experience gained by the surgeon and the addition of a cannula reduced the risk of conversion. CLINICAL RELEVANCE/IMPACT Laparoscopic cholecystectomy can be performed with a SPAS. The placement of an additional cannula at the beginning of the procedure is highly recommended.
