Bianchi A, Collivignarelli F, Vignoli M, Scaletta L, Cuomo A, Falerno I, Paolini A, Tamburro R. A Comparison of Times Taken for the Placement of the First Portal and Complication Rates between the Veress Needle Technique and the Modified Hasson Technique in Canine Ovariectomy Laparoscopic Surgery. Animals (Basel) 2021; 11:2936. [PMID: 34679957 PMCID: PMC8532732 DOI: 10.3390/ani11102936] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2021] [Revised: 09/22/2021] [Accepted: 10/06/2021] [Indexed: 11/26/2022] Open
Abstract
Minimally invasive surgery is increasingly being used in veterinary medicine. Laparoscopic procedures have several advantages compared with open surgery. These include the magnification of the field of surgery, reduced post-surgical pain and associated stress, reduced post-operative infection rates, and decreased hospitalization time. The establishment of a pneumoperitoneum is a critical step; however, this procedure can prolong the operation time, and most of the complications associated with laparoscopic surgery have been attributed to the insertion of devices into the abdominal cavity. Two main techniques have been employed to create pneumoperitoneum: the closed-entry method using the Veress needle and the open Hasson technique. The first portal is necessary to start insufflation and, subsequently, to realize the operative channel to insert the laparoscopic instruments into the abdomen. Many authors have compared the time necessary to create the first portal using different techniques in human medicine, but studies on this topic in veterinary medicine are lacking. In the veterinary medicine literature, complications associated with the creation of a pneumoperitoneum and the placement of ports include spleen, bowel, or bladder injuries; pneumothorax; and subcutaneous emphysema. The aim of the present study was to compare the times required for the placement of the first portal and the creation of pneumoperitoneum, and the rates of intraoperative complications using the Veress needle technique (VNT) and the open modified Hasson technique (MHT). The sample population comprised 30 female dogs who underwent laparoscopic ovariectomies. The dogs were randomly organized into two groups and two different entry techniques were used: Veress needle (VNT = group A) and the modified Hasson technique (MHT = group B). Complications related to abdominal entry were classified as major, in cases of organ perforation, and minor, in cases of subcutaneous emphysema and gas leakage. The VNT and MHT required 374.0 s and 242.9 s, respectively, for the placement of the first portal and for establishing pneumoperitoneum (p < 0.05). Their major complications rates were 20% and 0%, respectively (p < 0.05). Their minor complications rates were 20% and 35%, respectively (p < 0.05). No surgical procedures required laparotomy. The MHT was associated with a lower major complication rate and required less time to create the first portal, compared with the Veress needle technique.

[PMID: 34433462 PMCID: PMC8390292 DOI: 10.1186/s12917-021-02958-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2021] [Accepted: 07/07/2021] [Indexed: 11/19/2022] Open
Abstract
Background Recent advances in laparoscopy both in human and veterinary medicine have looked at means of being less invasive by using single-port access surgery as opposed to multiport access surgery. The glove port has gained popularity as a cost-effective alternative to commercially available single-port access devices. The primary aim of this study was to compare the glove port to the SILS™ port in a simulator model using the first two MISTELS (McGill inanimate system for training and evaluation of laparoscopic skills) tasks (peg transfer and pattern cutting). Methods Twenty-two novices were enrolled in this experimental study. Each participant had 60 min to practise both MISTELS tasks using two-port laparoscopy. Thereafter participants performed both tasks using the glove and SILS™ port with scores being calculated based on task completion time and errors. Higher scores were indicative of better performance. Participants were assigned into two groups with the starting order of the single ports being randomly selected. A self-evaluation questionnaire with three questions was completed by each participant after testing, rating each port. Results Significantly (p < 0.05) higher scores were achieved using the glove port compared to the SILS™ port when performing both tasks. The glove port was subjectively evaluated as easier to use with more manoeuvrability of the instruments than the SILS™ port. Implications of the study The glove port’s improved manoeuvrability and ease of use make it a cost-effective alternative to the SILS™ port, for use in single-port laparoscopic veterinary surgery.

Vet Sci 2021; 8:vetsci8080144. [PMID: 34437466 PMCID: PMC8402624 DOI: 10.3390/vetsci8080144] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2021] [Revised: 07/18/2021] [Accepted: 07/26/2021] [Indexed: 12/15/2022] Open
Abstract
In veterinary surgery, single incision laparoscopic surgery (SILS) techniques have been described since 2009, and, in recent decades, many authors have reported the application of SILS in small animals, thus, promoting the wide dissemination of this novel approach among veterinary laparoscopists. The aim of this literature review is to provide a critical evaluation of the scientific reports on SILS in the field of small animal laparoscopic surgery. A comprehensive literature review was performed including from 1 January 2009 to 1 July 2020. The following data were recorded from each study: the design, year of publication, surgical procedure, species, number of animals included, and surgical time. The type of SILS technique and type of control group technique were evaluated. In total, 90 articles were identified through database searches and manual searches. The qualitative analysis showed that most of the articles were retrospective studies, without a control group or case series. A meta-analysis was performed on the eight controlled studies, showing that SILS ovariectomy and gastrointestinal procedures had a comparable surgical time to multiport techniques. The study of the articles available in the veterinary literature did not allow for an adequate meta-analysis of the published results, especially regarding post-operative pain, evaluations of surgical times, and post-operative complications in comparison to multiport techniques. Therefore, veterinary surgeons who want to employ these techniques must consider the real advantages of SILS techniques.

Abstract
OBJECTIVE To describe the perioperative characteristics and outcomes in dogs that underwent transperitoneal laparoscopic ureteronephrectomy (TLU) for primary renal neoplasia. STUDY DESIGN Short case series. ANIMALS Seven client-owned dogs. METHODS Medical records were reviewed and data extracted regarding perioperative characteristics and animal outcomes. TLU was performed using a single-port + 1 or multiple port techniques. Hemostatic clips or a vessel-sealing device were used for occlusion of renal hilar vessels. The ureter was occluded and transected close to the ureterovesicular junction and the tumor was placed in a specimen retrieval bag for extraction from the abdomen. RESULTS Preoperative contrast enhanced computed tomography (CECT) was performed in 6/7 dogs. Median estimated tumor volume measured from abdominal CECT removed by TLU was 32.42 cm3 (interquartile range [IQR] 14.76-94.85). Median surgery time for TLU was 90 minutes (IQR 85-105). In one dog, elective conversion to open laparotomy was performed due to large tumor size. Median time to discharge was 31 hours (IQR 24-48). No major perioperative complications occurred and all dogs survived to discharge. Progression free survival in four dogs was 422 days (IQR 119-784). CONCLUSION TLU was performed for the extirpation of modest sized primary renal tumors with acceptable perioperative outcomes and a low complication rate. CLINICAL RELEVANCE TLU may be considered for the treatment of selected cases of primary renal neoplasia in dogs.

Abstract
OBJECTIVE To describe the use of the T'LIFT transabdominal organ retraction device to suspend ovaries during canine laparoscopic ovariectomy (LapOVE) and compare its use to a transabdominal suspension suture (TSS). DESIGN Randomized clinical trial. ANIMALS Client-owned intact bitches (n = 30). METHODS Dogs were randomly assigned either to group T, in which LapOVE was performed with the T'LIFT, or to group S, in which a TSS was used. Laparoscopic ovariectomy was performed by using a standard two-portal protocol. Signalment (age, weight, body condition score [BCS], fat score of the ovarian pedicle [FSOP]), overall operative time, ovarian resection time, and perioperative complications were compared between groups. RESULTS No significant differences were found between groups regarding age, weight, BCS, or FSOP. Surgical times were not significantly different between groups. No significant differences in major or minor complications were recorded. Overall operative time was significantly shorter for the last half of the cases compared with the first half, for the overall population, and within each group. Ovarian resection time for the last cases was significantly shorter compared with that for the first ones only in group T. CONCLUSION The T'LIFT was used to suspend ovaries for two-portal LapOVE, with no major complications noted. There was no significant difference in surgical times or complications compared with transabdominal suturing. CLINICAL SIGNIFICANCE The T'LIFT can be considered as an alternative to transabdominal suture for ovarian suspension in dogs undergoing LapOVE.

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.

Abstract
Ovarian remnant syndrome (ORS) is a condition resulting from incomplete removal of ovarian tissue during ovariectomy and/or ovariohysterectomy. Single-port laparoscopy (SPL) is an alternative to ventral midline laparotomy for treatment of ORS. Medical records of 13 client-owned female dogs who underwent SPL for the treatment of ORS were retrospectively reviewed to evaluate surgical technique and outcome. Dogs who had undergone a previous attempt at open ovariectomy or ovariohysterectomy were included. Major intraoperative complications did not occur and conversion to open laparotomy was not required. In 1 dog, an SPL + 1 technique was used, in which an additional port was placed cranial to the single-port device to aid in dissection and tissue manipulation. Median surgical time was 45 min (range, 30-90 min). Clinical signs related to estrus had resolved in 11 of 13 dogs with a median follow-up time of 18 mo. Two of 13 dogs were lost to follow-up at 3 mo postoperatively; however, signs of estrus had resolved at time of last follow-up. SPL treatment for ORS was feasible and successful in this cohort of dogs. Reduced surgical time was found in this study compared with previous reports investigating multiple-port laparoscopic treatment of ORS.

Abstract
OBJECTIVE To determine the frequency and types of paramedian incisional complications after prophylactic laparoscopy-assisted gastropexy (LAG) in dogs and to evaluate potential risk factors for complications. STUDY DESIGN Multi-institutional retrospective study. ANIMALS Client-owned dogs (N = 411). METHODS Records for dogs that underwent single-incision-port laparoscopy-assisted gastropexy (SIPLAG) or multiple-port laparoscopy-assisted gastropexy (MPLAG) at five veterinary referral hospitals were reviewed. Information regarding signalment, surgical procedures, perioperative care, and incisional complications was collected. Follow-up information was obtained by review of medical records and/or communication with owners. Potential risk factors for complications were examined statistically. RESULTS Paramedian incisional complications were observed in 78 of 411 (19%) dogs. The most common complication was seroma formation, which occurred in 51 (12.4%) dogs. Surgical site infections were observed in 16 (3.9%) dogs, and dehiscence or development of excessive scar tissue at the incision site were each observed in nine (2.2%) dogs. Complications resolved with conservative treatment in 75 of 78 (96.2%) dogs and with surgical treatment in three of 78 (3.8%) dogs. The odds of complications were approximately twice as high in dogs undergoing SIPLAG than in dogs undergoing MPLAG (odds ratio, 2.03; P = .006). CONCLUSION Minor paramedian incisional complications, particularly seroma formation, were frequently observed after LAG. Most complications were successfully managed conservatively. Single-incision-port laparoscopy-assisted gastropexy was associated with a higher complication rate compared with MPLAG. CLINICAL SIGNIFICANCE Owners should be informed that there is a relatively high rate of minor paramedian incisional complications after LAG. The risk of complications appears to be higher for SIPLAG than for MPLAG.

Abstract
Objective To describe a single‐port laparoscopic‐assisted ovariohysterectomy (LOHE) with a modified glove‐port technique in dogs and compare it with previously published laparoscopic techniques for LOHE in dogs. Study design Prospective clinical study and technique description. Animals Forty‐two healthy female dogs. Methods Laparoscopic‐assisted ovariohysterectomy was performed with a custom‐made single‐port device. The total duration of surgery from first incision to skin closure was compared with previously published durations of LOHE in dogs. Short‐term complications were recorded. Results The median total duration of surgery was 24 minutes (range, 17.5–39.5; mean, 25.73; SD, 6.12), which was shorter than that described in most previously reported studies of LOHE in dogs (range, 20.8 ± 4.00–60.0 ± 18.45 minutes; P < .001). Intraoperative complications were minor, but wound complications occurred in 12 of 42 (29%) dogs. Conclusion Single‐port LOHE with the glove‐port technique in combination with a wound retractor and nonarticulated instruments was completed in all dogs. This technique was faster than what has been previously reported for other LOHE, but local wound complications were common. Clinical relevance The glove‐port technique described here offers a low‐cost alternative to other commercially available single‐port devices.

Abstract
OBJECTIVE To review reported complications related to the different laparoscopic entry techniques in the human and veterinary literature and describe the benefits and limitations of each technique. STUDY DESIGN Literature review of 57 peer-reviewed articles. METHODS An electronic database search identified human and veterinary literature describing complications related to entry technique during laparoscopy. RESULTS Open- and closed-entry techniques may result in trauma of abdominal organs or vasculature. During laparoscopy in man, injury to bowel and major vasculature is reported in 0.02% and 0.04% of procedures with open- or closed-entry techniques, respectively. Designs of Veress needles and trocar cannula assemblies have been developed to improve ease and safety. Early complications, defined as those observed at the time of port entry into the abdominal cavity, result from the puncture of a blood vessel leading to substantial visible hemorrhage. Late complications are detected 24 or 48 hours after surgery and result from the puncture of a loop of intestine that was not detected at the time of initial surgery. The major reasons for iatrogenic trauma in man are related to anatomical factors and the presence of adhesions. No explanation for cause of complications was identified for animals. CONCLUSION There is no consensus in the human or veterinary literature about the best entry technique for laparoscopy. The rate of complications related to entry technique in small animals is not known because the data are underreported. CLINICAL SIGNIFICANCE Complications related to entry techniques are expected in both man and animals. Improvements in techniques and equipment design are being developed to minimize risk.

Abstract
CASE DESCRIPTION 7 privately owned female African lions (Panthera leo) that had been bred for public exhibition and were housed in outdoor pens were evaluated prior to undergoing elective ovariectomy. CLINICAL FINDINGS All animals were healthy. Median age was 15 months (range, 9 to 34 months), and median body weight was 71 kg (156 lb; range, 48 to 145 kg [106 to 319 lb]). TREATMENT AND OUTCOME Surgical sterilization by means of single-incision laparoscopic ovariectomy was elected. A 2- to 3-cm-long skin incision was made just caudal to the umbilicus, and a single-port multiple-access device was bluntly inserted through the incision. Traction was maintained with stay sutures to provide counterpressure, and three 5-mm-diameter cannulae were introduced through the device's access channels with a blunt trocar. The abdomen was insufflated to a pressure of 12 mm Hg with CO2. Each ovary was grasped and suspended with a standard 36-cm-long laparoscopic grasper, and ovariectomy was performed with a 5-mm vessel sealer and divider device. Because of the depth of subcutaneous fat, extensive subcutaneous dissection was necessary to insert the single-port device. In contrast, fat content of the mesovarium was minimal and did not vary markedly among animals. Subjectively, single-incision laparoscopic ovariectomy was easily performed, but all surgeons had experience in laparoscopic surgery. Median duration of the surgical procedure was 29 minutes (range, 21 to 49 minutes). No perioperative complications were encountered. CLINICAL RELEVANCE Findings suggested that the single-incision laparoscopic technique may be an acceptable, minimally invasive option for ovariectomy of large felids.

Abstract
OBJECTIVE To describe pet owner preferences within the veterinary community when choosing operative techniques for canine spay. STUDY DESIGN Prospective survey. SAMPLE POPULATION 1234 respondents from 5 veterinary university teaching hospitals in North America. METHODS An electronic survey was distributed to faculty, students, and staff that currently are or previously were dog owners. Responses were analyzed to determine what spay technique respondents would choose for their own dogs. Surgical options offered included open celiotomy, 2-port (TP) laparoscopy, single-port (SP) laparoscopy, and natural orifice transluminal endoscopic surgery (NOTES). RESULTS TP laparoscopic ovariectomy (OVE) was the most popular choice, followed by SP laparoscopic OVE; NOTES was the least popular technique when all surgical options were available. If only minimally invasive surgeries were offered, 0.3% of respondents would refuse surgery. Nearly half (48%) of respondents were willing to spend between $100 and $200 more for a minimally invasive OVE than for an open celiotomy. CONCLUSION Minimally invasive OVE is an acceptable operative approach to those in the veterinary community. Additional study is required to correlate these findings with the general veterinary client population.

Abstract
Vaginoscopy allows for diagnostic evaluation and treatment of the vaginal vault. A laparoscopic surgical port device and rigid telescope were utilized for serial vaginoscopy in 8 healthy anesthetized ewes. Vaginoscopy examinations were performed in each ewe at days 1, 14, and 28. This technique was well-tolerated and facilitated carbon dioxide vaginal inflation, complete vaginal examination, identification of the cervix, and targeted biopsy collection. No complications were encountered during or following the vaginoscopy procedures. The laparoscopic port device was well-suited to the ewe vulvar size. This technique could be applied to clinical evaluation in ewes for the purposes of examination, biopsy, culture, foreign body removal, and minor surgical procedures.

Abstract
In the present study, we investigated the course of atrophy in canine uterine tissue and the expression of estrogen receptors (ER) and progesterone receptors (PR) within 6 months after ovariectomy (OE). In nine primipar bitches of different breeds, bilateral OE and removal of one horn was performed. Six months after surgery, the remaining uterine tissue was removed. The tissue was examined for signs of inflammation and proliferation, and for expression of ER, PR and Ki67 by means of immunohistochemistry (IHC); furthermore transcription of vascular endothelial growth factor (VEGF), transforming growth factor-ß (TGF-ß), epithelial growth factor (EGF), platelet activating factor (PAF), tumor necrosis factor α (TNFα), and their specific receptors was determined by means of RT-qPCR. Serum concentrations of estrogen and progesterone were measured immediately before the first and second operation. Six month after OE, no inflammation was seen in any uterine tissue, the thickness of the stump was decreased in most bitches. Protein expression of Ki67 revealed high individual differences after the second operation. Concentration of both hormones was not significantly changed, the estrogen concentration always revealed high individual differences. The expression of ER was significantly decreased in stromal and smooth muscle cells of the uterine tissue (p < 0.01), and the expression of PR in stromal cells only (p < 0.05). The gene expression of growth factors did not change significantly between first and second operation. We conclude that complete atrophy did not occur within 6 months after OE, instead, a high percentage of uterine cells still expressed ER and PR, rendering the stump susceptible to hormone treatments.

Abstract
OBJECTIVE To describe a technique for laparoscopic incisional gastropexy using an articulated endoscopic suturing device with knotless unidirectional barbed suture in healthy large breed dogs. STUDY DESIGN Prospective case series. ANIMALS Healthy client-owned dogs presented for prophylactic gastropexy and weighing >20 kg (n=7). METHODS Incisional gastropexy was performed using a single port access system with an articulated endoscopic suturing device. An additional 5 mm cannula was placed in the right caudal abdomen. A 2-0 knotless unidirectional barbed suture was used to complete the gastropexy with 2 separate simple continuous suture lines. All dogs underwent a focal abdominal ultrasound to evaluate the gastropexy site 3-12 months postoperatively. RESULTS Median weight of the dogs was 33.5 kg (range, 20-51 kg) and the median age was 2 years (range, 0.6-8.5 years). Median surgical time was 60 minutes (range, 39-88). The articulated suturing device malfunctioned twice. On abdominal ultrasound between 3 and 12 months, all gastropexy sites were intact. No motion was detected between the stomach and body wall during distal antral contractions or respiratory motion and a focal thickening of the gastric wall was present in dog. No complications were reported in the postoperative periods as of the 2 week suture removal visit or as of the time of their ultrasound appointment. CONCLUSION This technique using an endoscopic articulated suturing device with a knotless unidirectional barbed suture provides a feasible technique to perform laparoscopic gastropexy.

Effect of portal access system and surgery type on surgery times during laparoscopic ovariectomy and salpingectomy in captive African lions and cheetahs. Acta Vet Scand 2016; 58:18. [PMID: 26935755 PMCID: PMC4776378 DOI: 10.1186/s13028-016-0199-2] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2015] [Accepted: 02/23/2016] [Indexed: 11/12/2022] Open
Abstract
Background A prospective randomized study was used to compare surgery times for laparoscopic ovariectomy and salpingectomy in female African lion (Panthera leo) (n = 14) and cheetah (Acinonyx jubatus) (n = 20) and to compare the use of a multiple portal access system (MPAS) and single portal access system (SPAS) between groups. Two different portal techniques were used, namely MPAS (three separate ports) in lions and SPAS (SILS™ port) in cheetahs, using standard straight laparoscopic instruments. Portal access system and first ovary was not randomized. Five different surgery times were compared for the two different procedures as well as evaluating the use and application of MPAS and SPAS. Carbon dioxide volumes for lions were recorded. Results In adult lionesses operative time (OPT) (P = 0.016) and total surgical time (TST) (P = 0.032) were significantly shorter for salpingectomy compared to ovariectomy. Similarly in cheetahs OPT (P = 0.001) and TST (P = 0.005) were also shorter for salpingectomy compared to ovariectomy. In contrast, in lion cubs no difference was found in surgery times for ovariectomy and salpingectomy. Total unilateral procedure time was shorter than the respective bilateral time for both procedures (P = 0.019 and P = 0.001) respectively and unilateral salpingectomy was also faster than unilateral ovariectomy (P = 0.035) in cheetahs. Port placement time, suturing time and TST were significantly shorter for SPAS compared to MPAS (P = 0.008). There was, however, no difference in OPT between SPAS and MPAS. Instrument cluttering with SPAS was found to be negligible. There was no difference in mean volume CO2 required to complete ovariectomy in lions but the correlation between bodyweight and total volume of CO2 in lions was significant (rs = 0.867; P = 0.002). Conclusions Laparoscopic salpingectomy was faster than ovariectomy in both adult lions and cheetahs. Using SPAS, both unilateral procedures were faster than bilateral procedures in cheetahs. Placement and suturing of SPAS in cheetahs was easier and faster compared to three separate ports in lions and lion cubs. The use of standard straight instruments during SPAS did not prolong surgery. Surgery was faster in cubs and CO2 required for laparoscopic sterilization in lions could be determined. Predictable surgery times and CO2 volumes will facilitate the accurate planning and execution of surgery in lions and cheetahs.
