Objective— To report a technique for incisional hernioplasty in horses using laparoscopic placement of a prosthetic mesh.
Study Design— Case series.
Animals— Horses (n=5) with ventral median abdominal incisional hernia.
Methods— A telescope and 2 instrument portals were established bilaterally, lateral to and distant from the hernia margins. After exposure of the internal rectus sheath by removal of retroperitoneal fat with endoscopic scissors and monopolar cautery, a prosthetic mesh was introduced into the abdomen and secured intraperitoneally using transfascial sutures with or without supplemental endoscopic hernia fixation devices.
Results— Successful placement of the prostheses was achieved without major intra- or postoperative complications. Repairs were intact in all horses (follow-up range: 6–23 months) without evidence of adhesion formation. Cosmetic results compared favorably with those typically achieved using conventional, open hernioplasty techniques.
Conclusion— Incisional hernia repair in horses can be successfully achieved with a laparoscopic intraperitoneal mesh onlay technique.
Clinical Relevance— Laparoscopic mesh hernioplasty has promise as a safe and effective method for repair of incisional hernias in horses. 相似文献

Objective— To report a technique for repair or prevention of inguinal hernia in horses using intracorporeal suture closure of the internal inguinal and vaginal rings.
Study Design— Case series.
Animals— Foals (n=6) and geldings (n=2).
Methods— After selection of a peri-umbilical telescope portal, instrument portals were made unilaterally or bilaterally, as needed. Herniated viscera was reduced, castration (foals) or spermatic cord remnant transection at the internal inguinal ring (adults) performed, and then simple interrupted intracorporeal sutures of synthetic absorbable suture material were used to close the internal inguinal and vaginal rings.
Results— There was no recurrence of inguinal hernia. Postoperative morbidity was minimal and cosmetic outcome was comparable to that achieved with conventional, open techniques.
Conclusion— Laparoscopic, primary closure of the internal inguinal ring by use of intracorporeal sutures provides a secure barrier to herniation and costs considerably less than using endoscopic staples.
Clinical Relevance— Laparoscopic suture closure of the internal inguinal and vaginal rings provides safe and effective repair of inguinal hernia in horses. 相似文献

Objective —To report a ventral abdominal approach and a ligating loop technique for laparoscopic cryptorchidectomy in horses.
Study Design —Prospective.
Sample Population—Six horses, aged 1 to 5 years, with retained testes.
Methods —One laparoscopic portal and three to four instrument portals were used for ventral abdominal laparoscopic cryptorchidectomy. Laparoscopic instruments were used to maneuver and secure the testis through a ligating loop (modified Roeder knot) that was secured from outside the abdominal cavity. Only minimal enlargement of one instrument portal was used to remove the testicle.
Results —Three horses were bilateral cryptorchids, and three were unilateral (left side, two; right side, one) cryptorchids. Operative time, defined as the time from laparoscope insertion to removal, ranged from 20 to 25 minutes for unilateral cryptorchids and from 40 to 50 minutes for bilateral cryptorchids.
Conclusions —The reported technique allowed decreased tension on the tissues during ligation and removal of the testis from the peritoneal cavity. Improved observation of the abdominal cavity, ligation security, shortened patient confinement time, and minimally invasive technique are all considered to be benefits of laparoscopic cryptorchidectomy.
Clinical Relevance —Direct observation of retained testes and intraabdominal castration are distinct advantages of the use of laparoscopy in horses that have had previous unsuccessful surgical attempts, horses with unknown histories that have retained testicular tissue, or bilateral abdominal cryptorchids. 相似文献

Laparoscopic hernioplasty techniques have been developed in the recent years to avoid the recurrence of inguinal hernias and to spare the testicles for breeding purposes in stallions. However, there have been no previous comprehensive and systematic studies of the reproductive outcomes and prognoses for stallions after inguinal hernioplasty. Therefore, the objective of this study was to assess the possible effects of one of these techniques (standing laparoscopic peritoneal flap hernioplasty) on the sperm production and motility characteristics of six healthy stallions that received this procedure based on 1‐year follow‐ups. There were no significant differences in the measured sperm variables (assessments based on the DSO, MOT, PMOT, VSL, VCL and VAP) during 1‐year follow‐ups. 相似文献

Peritoneal d-Dimer Concentration for Assessing Peritoneal Fibrinolytic Activity in Horses with Colic
M.A. Delgado L. Monreal L. Armengou J. Ríos D. Segura 《Journal of veterinary internal medicine / American College of Veterinary Internal Medicine》2009,23(4):882-889
Background: Plasma d -dimer concentration is a useful marker to assess systemic coagulation and fibrinolytic activities in humans, dogs, and horses. Peritoneal fibrinolytic activity increases in horses with colic, especially in horses with endotoxin in the peritoneal fluid.
Hypothesis/Objectives: Peritoneal d -dimer concentration can be used to assess peritoneal fibrinolytic activity in horses with severe gastrointestinal (GI) disorders and altered peritoneal fluid.
Animals: Two hundred and twenty-one colic horses and 15 control horses.
Methods: Prospective observational clinical study. Blood and peritoneal fluid were collected on admission. Horses were grouped according to diagnosis, peritoneal fluid analysis, and outcome. Peritoneal d -dimer concentration was determined, together with peritoneal tissue-plasminogen activator (t-PA) and plasminogen activator inhibitor (PAI-1) activities. Plasma d -dimer concentration also was measured.
Results: Peritoneal d -dimer concentration was significantly higher in all colic groups compared with controls, and in horses with enteritis, peritonitis, and ischemic disorders compared with horses with large intestinal obstructions. Peritoneal d -dimer concentration was significantly higher in horses with altered peritoneal fluid (modified transudate and exudate) compared with horses with normal peritoneal fluid analysis. Plasma d -dimer concentration also was significantly higher in the peritonitis group, and in horses with altered peritoneal fluid analysis. Peritoneal and plasma d -dimer concentrations also were significantly higher in nonsurvivors. Peritoneal d -dimer concentration was significantly correlated with decreased peritoneal t-PA activity and increased peritoneal PAI-1 activity.
Conclusions and Clinical Importance: Peritoneal d -dimer concentration is markedly higher in severe GI disorders, and it can be used to assess peritoneal fibrinolytic activity in horses with colic. 相似文献

Three feeding methods were compared in 36 4- to 6-year-old Franche-Montagne horses during the military school of St-Luzisteig (GR) of Spring 1992. The horses were separated into 3 groups: a group with the traditional oats-hay ration (OH), a group with a pelleted feed and hay ration (PFH), and a group with the complete diet (CD). Feed analyses were performed and food consumption, eating behavior and digestibility were studied. The horses received their daily amount of feed in 3 portions covering the requirements for a medium work: OH = 8 kg hay and 3 kg oats, PFH = 8 kg hay and 3 kg pelleted feed and CD = 10 kg of the complete diet. For the 3 rations, the amount of digestible crude protein for horses was higher than the reference value for the requirement of a 600 kg horse with a medium work. In the 3 diets, the calcium content was higher than the required 32 g per day (g/d). Not enough sodium (OH: 1.2 g/d; PFH: 7.3 g/d; CD: 9.6 g/d) and too much potassium (OH: 140.3 g/d; PFH 153.0 g/d; CD: 167.5 g/d) were present in the diets, both without consequences for the blood parameters. In 3 meals of 60 minutes, the horses of the group OH, PFH and CD ingested 82%, 89% and 92%, respectively, of the daily ration. The complete diet was ingested more quickly than the hay. The number of mastications per minute was smaller for the complete diet than for the hay. Ingestion times were similar for oats and pelleted feed. However, the number of mastications per minute was smaller for the pelleted feed. The digestibility of nutrients was not influenced by the method of feeding. In conclusion, these results demonstrate that the 3 types of ration studied here are adequate for the swiss army horses if sodium is added to the diet. However, despite the fact that both PFH and CD correct excessive supply or deficiencies of nutrients and despite the fact that these two feeding methods offer nutrients in amounts that are closer to the requirements of the horse, the method PFH was introduced in 1994. 相似文献

Effect of Ischemia and Reperfusion on Neutrophil Accumulation in Equine Microvascular Tissue Flaps 总被引：1，自引：0，他引：1
W. Michael Scott DVM MVSc Diplomate ACVS J. David Fowler DVM MVSc Diplomate ACVS Gilbert Matte PhD rew L. Allen DVM MVSc PhD A. A. Wilkinson MA MB BChir MSc FRCPC Jeremy V. Bailey BVSc MVSc Diplomate ACVS Peter B. Fretz VMD Diplomate ACVS 《Veterinary surgery : VS》1999,28(3):180-187
Objective— To investigate neutrophil accumulation after ischemia and reperfusion (IR) in microvascular tissue flaps in horses.
Study Design— Randomized controlled experiment.
Sample Population— A total of 8 horses between 1 and 10 years of age, 4 of each sex.
Methods— Control and experimental myocutaneous island flaps based on the superficial branch of the deep circumflex iliac vessels were dissected on each horse. Atraumatic vascular clamps were applied to the pedicle of the experimental flap for 90 minutes and then removed to allow reperfusion. Based on the assumption that rapid infiltration of neutrophils into affected tissues is a hallmark of IR injury, radiolabeled autogenous leukocytes were used to indirectly quantify neutrophil accumulation in flap tissues. Labeled leukocytes were administered through a jugular catheter 30 minutes before flap reperfusion. Biopsies were collected from each flap over a 6 hour postischemia time period; in group 1 ( n = 4 ) from 0 to 6 hours postischemia, and in group 2 ( n = 4 ) from 24 to 30 hours postischemia. Biopsies were examined scintigraphically and histologically for evidence of neutrophil infiltration.
Results— All control flaps survived and 6 of 8 experimental flaps survived. There was no significant evidence of acute neutrophil infiltration into flap tissues after reperfusion in either group.
Conclusions— The results of this study suggest that equine myocutaneous flap tissues can survive a 90-minute ischemic period and reperfusion. No significant evidence of the occurrence of IR injury in flap tissues was found.
Clinical Relevance— The reasons for the previously reported failures of equine free tissue transfer remain uncertain, but they do not appear to be caused by neutrophil mediated injury associated with ischemia and reperfusion. 相似文献

Objective —To evaluate the postoperative use of peritoneal lavage for prevention of experimentally induced intraabdominal adhesions in horses.
Study Design —Areas of serosal abrasion were created on the jejunum of 12 horses. Postoperatively, six horses had peritoneal lavage, and six horses did not (controls). The number of adhesions was determined at necropsy 2 weeks after surgery.
Animals or Sample Population—12 horses.
Methods —Five sites of jejunal serosal abrasion were created in each horse. A 32 French thoracic catheter was placed into the right ventral aspect of the abdomen before closure of the abdominal incision. Treated horses had abdominal lavage with 10 L of lactated Ringer's solution on four occasions, then catheters were removed from all horses 34 hours after celiotomy. Horses were necropsied at 2 weeks to quantify the number of intraabdominal adhesions.
Results —All control horses and one treated horse developed intraabdominal adhesions. The number of adhesions was significantly less ( P <.0293) in treated horses. No adverse inflammatory reactions appeared to be associated with repeated peritoneal lavage using lactated Ringer's solution or use of an abdominal drain.
Conclusions —Peritoneal lavage reduced the frequency of intraabdominal adhesions.
Clinical Relevance —When postoperative adhesions are likely to develop, postoperative peritoneal lavage may decrease the frequency of adhesion formation. 相似文献

Background: Peritoneal D-Dimer concentration can be determined to assess peritoneal fibrinolysis activity in horses with gastrointestinal disorders. However, blood contamination of peritoneal fluid may occur during collection and could alter peritoneal D-Dimer concentration.
Hypothesis/Objectives: Blood contamination in peritoneal fluid does not affect interpretation of peritoneal D-Dimer concentration in horses with colic.
Animals: Thirty-four horses with colic and 4 healthy horses.
Methods: Peritoneal fluid and blood samples were simultaneously collected upon admission. Then, peritoneal fluid was serially contaminated with the horse's own blood; final contaminations corresponded to 1, 5, 10, and 20% of blood in peritoneal fluid. D-Dimer concentration was determined in blood, peritoneal fluid, and contaminated peritoneal fluid samples. Data were analyzed using a longitudinal linear model and a generalized estimating equations analysis to assess the quantitative and qualitative variations of the effect of blood contamination on peritoneal D-Dimer concentration.
Results: Peritoneal D-Dimer concentration was only quantitatively affected when peritoneal fluid was contaminated at 20% of blood. However, when using increasing cut-off values of peritoneal D-Dimer concentration (100, 2,000, 8,000, and 16,000 ng/mL), this effect disappeared at the highest cut-off values (8,000 and 16,000 ng/mL). When peritoneal fluid contamination was grouped as "minimally contaminated" (≤1% of blood) and "highly contaminated" (≥5% of blood), no significant differences on D-Dimer concentration between both groups at each cut-off value were observed.
Conclusions and Clinical Importance: Although quantitative results of peritoneal D-Dimer concentration could be affected by high levels of blood contamination (≥20%), interpretation of increased peritoneal fibrinolytic activity was not significantly affected. 相似文献

Laparoscopic cryptorchidectomy was successfully performed in 15 standing or recumbent horses. In 3 horses, owners believed that castrations had been performed, but the horses had retained stallion-like behavior. Successful removal of undescended testes in these horses stopped this behavior. Laparoscopy offered excellent visualization of the structures of the vaginal ring and facilitated removal of the abdominally located testis. The internal and external inguinal rings were not invaded, thus the chance of serious complications that may result during open cryptorchidectomy procedures was minimized. 相似文献

OBJECTIVE: To describe surgical technique and outcome after laparoscopic closure of the nephrosplenic space for treatment of recurrent left dorsal displacement of the left colon (LDDLC) in standing horses. STUDY DESIGN: Retrospective study. ANIMALS: Forty-four horses with LDDLC. METHODS: Laparoscopic portals were located in the left flank region. After administration of etilefrin intravenously to contract the spleen, the dorsal splenic margin was sutured to the nephrosplenic ligament to obliterate the nephrosplenic space. Horses were re-examined (< or = 3 years) for history of recurrence. In addition, medical records of 4,852 horses treated for colic over 16 years were evaluated to establish incidence of LDDLC and recurrence after treatment. RESULTS: Splenic contraction facilitated suture placement and closure of the nephrosplenic space was achieved without complications. LDDLC recurrence did not occur although 5 horses had subsequent episodes of colic; 4 horses had displacement of the ascending colon between the spleen and body wall. Review of medical records revealed an incidence of LDDLC of 6% and recurrence of 21% in a population of horses with signs of colic. CONCLUSION: Laparoscopic closure of the nephrosplenic space, facilitated by etilefrin-induced splenic contraction can be efficiently performed in standing horses. CLINICAL RELEVANCE: Laparoscopic ablation of the nephrosplenic space should be considered in horses that are predisposed to recurrent LDDLC. 相似文献

A 7-month-old Hampshire ram, with no history of trauma or breeding, was referred for treatment of acute, unilateral scrotal swelling. Physical examination revealed a moderately sized, soft, left-sided, non-reducible swelling of the proximal scrotum and mild swelling of the scrotal neck. Ultrasound evaluation of the scrotum revealed morphologically normal testicles and a mild accumulation of free fluid in the left vaginal tunic. Unilateral, laparoscopic inguinal herniorrhaphy under general anesthesia was performed. The herniated omentum was reduced and barbed suture was used to imbricate the internal inguinal ring and the vaginal ring. No recurrence of herniation was reported 5 months after surgery.Key clinical message:Laparoscopic inguinal herniorrhaphy with barbed suture can be a safe and effective means of scrotal hernia resolution in a ram. When performed by a competent surgeon experienced in laparoscopy, this treatment for inguinal and scrotal herniation may minimize post-operative pain, provide a rapid return to function, and preserve normal testicular and scrotal anatomy. 相似文献

Objectives – To present a case series of horses diagnosed with diaphragmatic hernia, and to determine the significance of (1) historical information, examination findings, and laboratory data; and (2) exploratory laparotomy or necropsy findings on short- and long-term outcome.
Setting – University Referral Hospital.
Design – Retrospective study.
Animals – Forty-four horses/foals admitted between 1986 and 2006 with a diagnosis of diaphragmatic hernia made either at exploratory laparotomy or necropsy.
Interventions – None.
Measurements and Main Results – Information from the medical records included history, clinical examination findings at presentation, and findings of exploratory laparotomy or necropsy. Logistic regression or the Fisher exact test was used to determine factors associated with survival. Outcome was defined as survival to discharge (short-term survival), and long-term survival was defined as horses alive at least 1-year post surgery. Of the 44 horses, 18 died or were euthanized before surgery. Twenty-six were taken to surgery, 17 were euthanized. Nine horses recovered from anesthesia, 7 of which survived to hospital discharge. Of these, 5 were alive at long-term follow-up. Survival was significantly associated with the age of the horse (≤2 y old) at presentation, presence of normal peritoneal fluid at presentation, amount of compromised viscera at surgery (<50% small intestine), and the size (<10 cm) and location (ventral) of the diaphragmatic tear.
Conclusion – This study confirms that size and location of the lesion do play a significant role in prognosis. And, although the prognosis for horses with diaphragmatic hernia is poor, if horses have operable lesions there is a fair prognosis for long-term survival. 相似文献

The surgical success of laparoscopic castration without orchidectomy results from avascular necrosis of the testes. However, failures and subsequent production of testosterone and stallion‐like behaviour have been previously identified. Laparoscopic castration without removal of the testes was performed in 32 horses with 2 normal descended scrotal testes between July 2006 and October 2012. The objectives of our study were to evaluate the success rate of laparoscopic castration without orchidectomy on descended testes in our population and assess complications and recovery time. Endocrine tests were performed after surgery and owners also asked to report on their horse's behaviour and ability to resume exercise. Castration was deemed successful if endocrine test results were in accordance with gelding values. Failed horses were castrated using a conventional technique and histology performed when possible. Basal testosterone levels decreased below 3 nmol/l after surgery in 30/32 cases. However, in 2 horses, stallion behaviour persisted and histological evaluation after inguinal castration showed residual viable tissue. Two horses maintained high testosterone levels after surgery associated with stallion‐like behaviour. Based on these results, 12.5% of horses (4/32 horses) failed to be considered a gelding based on either endocrine tests and/or histology. All horses, with one exception, were able to resume exercise less than a week after the procedure. Laparoscopic castration without orchidectomy appears to be a safe procedure. When assessing the success of laparoscopic castration, our total failure rate was 12.5% (4/32 horses) which is significantly higher than previously reported. 相似文献

Laparoscopic Repair of Scrotal Hernia in Two Foals 总被引：1，自引：0，他引：1
Nonstrangulating indirect scrotal hernias were corrected in two 4-week-old Percheron foals by a laparoscopic technique. After laparoscopic reduction of herniated nonstrangulated small intestine each testes was retracted through the vaginal ring. The ligament of the tail of the epididymis was transected by electrocautery. The testicular vessels and nerves were isolated by cautery of the mesenteric portion of the mesorchium and then ligated. Staples were used to close the opening of the inguinal canal by apposing the peritoneal edges of the vaginal ring. Resection of umbilical stalk remnants via celiotomy performed in one foal after laparoscopic observation of enlargement of the right umbilical artery and urachus. No complications or recurrence of herniation had occurred 16 weeks after surgery. 相似文献

Objective— To report laparoscopic splenectomy in goats.
Study Design— Experimental study.
Animals— Healthy female goats (n=9); aged, 10–18 months; weighing, 22–30 kg.
Methods— Food was withheld for 24 hours and water for 10 hours. Anesthetized right laterally recumbent goats had a laparoscopic portal and 3 instrumental portals created in the left flank. Splenic attachments were dissected with monopolar electrocautery and blunt dissection through 2 instrument portals. Exposure and isolation of splenic vessels was performed with laparoscopic "right-angle" preparation forceps. Vessels were ligated with a medium-titanium clip and 2 silk sutures and then transected between the silk sutures. The detached spleen was manipulated into a specimen retrieval bag, morcellated, and the bag retrieved through an enlarged portal. Repeat laparoscopic examination was performed at 1 month.
Results— Laparoscopic splenectomy required 70 minutes (range, 52–88 minutes) and was successful without major intraoperative and postoperative complications. Postoperatively, all goats had signs of mild abdominal discomfort. On repeat laparoscopy, with the exception of 1 goat that had a focal omental adhesion to the enlarged portal site, no other abnormalities were identified.
Conclusions— Laparoscopic splenectomy can be accomplished in goats using 4 portals in the left flank and a combination of monopolar cautery dissection of splenic attachments, ligation of vessels using metal clips and intracorporeal ligatures, and intra-abdominal morcellation of the detached spleen in a specimen retrieval bag.
Clinical Relevance— Laparoscopic splenectomy is an effective and safe technique in goats. 相似文献
Study Design— Experimental study.
Animals— Healthy female goats (n=9); aged, 10–18 months; weighing, 22–30 kg.
Methods— Food was withheld for 24 hours and water for 10 hours. Anesthetized right laterally recumbent goats had a laparoscopic portal and 3 instrumental portals created in the left flank. Splenic attachments were dissected with monopolar electrocautery and blunt dissection through 2 instrument portals. Exposure and isolation of splenic vessels was performed with laparoscopic "right-angle" preparation forceps.

Objective — The purpose of this study was to determine the feasibility of using laparoscopy to remove cryptorchid testes from standing horses.
Study Design — Prospective clinical study.
Animals or Sample Population — Eleven client-owned horses ranging in age from 4 months to 2 years.
Methods — Abdominal insufflation was initiated and maintained using a 20 F insufflation tube, attached via a stopcock, to the low pressure regulator on a standard carbon dioxide pressure tank. After trocar and laparoscope placement in the ipsilateral flank the testes were identified. Local anesthesia of the structures to be manipulated was administered through the instrument channel on the operative laparoscope, using a catheter with a needle attached. Testes were grasped with large laparoscopic forceps and exteriorized through the abdominal wall. Ligation and transection of the mesorchium was extracorporeal. The descended testes were removed using a standard standing technique.
Results — Complications were minor, including mild colic in one horse. The mean surgical time for standing laparoscopic cryptorchidectomy and castration of these colts was 58.9 ±24.3 minutes.
Conclusions and Clinical Relevance — Standing laparoscopic cryptorchidectomy, using the instrumentation described, is a safe and practical technique in young horses. 相似文献

Laparoscopic adrenalectomy for treatment of unilateral adrenocortical carcinomas: technique, complications, and results in seven dogs 总被引：1，自引：0，他引：1
Objective— To investigate the feasibility of, and outcome after, laparoscopic adrenalectomy in dogs with unilateral adrenocortical carcinoma.
Study Design— Case series.
Animals— Dogs (n=7) with Cushing's syndrome caused by unilateral adrenocortical carcinoma.
Methods— Laparoscopic adrenalectomy with the dog in lateral recumbency on the unaffected side. Three 5-mm portals (1 laparoscopic portal, 2 instrument portals) were placed in the paralumbar fossa. A fourth instrumental portal (5–12 mm) was placed above the kidney. After dissection and hemostatic control of the phrenicoabdominal vein, the adrenal gland was carefully dissected or when there was capsule fragility, necrotic content was partially aspirated. The remaining glandular tissue was removed through the 12-mm trocar site.
Results— Dogs with unilateral adrenocortical carcinoma (3 right-sided, 4 left-sided) without invasion of the caudal vena cava were successfully operated by laparoscopic approach. There were no significant intraoperative complications; 2 dogs died within 48 hours of surgery because of respiratory complications. Five dogs were discharged 72 hours after surgery, and signs of hyperadrenocorticism disappeared thereafter (survival time ranged from 7 to 25 months).
Conclusions— Laparoscopic adrenalectomy is feasible in dogs with either right- or left-sided adrenocortical carcinoma not involving the caudal vena cava.
Clinical Relevance— When performed by experienced surgeons, laparoscopic adrenalectomy offers a minimally invasive alternative to open laparotomy or retroperitoneal surgery for the treatment of unilateral adrenocortical carcinoma in dogs. 相似文献

OBJECTIVE: To report a technique for laparoscopic ablation of the renosplenic space in standing horses. STUDY DESIGN: Development of a technique to perform laparoscopic renosplenic space ablation in standing horses. ANIMALS: Five healthy horses, aged 3 to 13 years, weighing 380 to 520 kg. METHODS: Horses were restrained in standing stocks and sedated with detomidine (0.01 mg/kg intravenously [IV]) and butorphanol (0.01 mg/kg IV). Portal sites in the left paralumbar fossa were infiltrated with 2% mepivacaine. A laparoscopic portal was placed between the 17th and the 18th ribs. Two instrument portals were located caudal to the 18th rib. Closure of the renosplenic space was accomplished by apposing the dorsomedial splenic capsule to the dorsal portion of the renosplenic ligament with 1 polyglactin 910 in a continuous pattern. All horses had repeat laparoscopy 3 weeks after initial surgery. RESULTS: Laparoscopic closure of the renosplenic space required 35 minutes (range, 20-65 minutes) and was successful without intraoperative or postoperative complications. On laparoscopic re-examination at 3 weeks, there was smooth connecting fibrous-like tissue between the dorsal splenic capsule and the dorsal portion of the renosplenic ligament. CONCLUSIONS: Laparoscopic closure of the renosplenic space can be efficiently and safely performed in standing horses. CLINICAL RELEVANCE: Laparoscopic-assisted closure of the renosplenic space can be performed in standing horses and may be useful in preventing recurrent incarceration of viscera in this space. 相似文献
