We prepared an anti-adhesion membrane made of sodium hyaluronate/sodium carboxymethylcellulose (HA/CMC) and evaluated its effectiveness for adhesion prevention in a rat model. The anti-adhesion membrane was prepared by lyophilizing HA/CMC solution and cross-linking properly with 1-Ethyl-3-(3-dimethylaminopropyl) carbodiimide (EDAC). In a cecum/abdominal wall abrasion model of Sprague-Dawley rat, cecal serosa and abdominal wall were abraded in $1\times2\;(cm^2)$ with a bone burr after peritoneal midline incision and sutured at 3 points around the injured surface. The denuded cecum was covered with HA/CMC membrane (experimental group), or nothing (control group) and apposed to the abdominal wall. Most of the control group represented 3 or more of adhesion grade at POD 7, 14, 21, and 28, whereas $60\~70\%$ of the experimental group was 2 or less of adhesion grade at 14, 21, and 28. It was similar in the adhesion strength. In a general manner, the adhesion grade and strength showed gradual increasing until POD 14, almost same or a little increasing POD 21, but decreasing POD 28. Also the control group was much higher in adhesion grade, strength, and area than the experimental group. It is expected that the anti-adhesion membrane will have a good clinical result in postoperative adhesion prevention.

Background: Intraoperative and postoperative ocular complications are rare. We retrospectively investigated the abnormal ocular findings in patients who underwent arthroscopic shoulder surgery. Methods: The records were investigated of patients who underwent shoulder arthroscopic surgery at our hospital between January 2018 and March 2019. Ocular complications were confirmed by review of medical records. We performed logistic regression analysis to defined the main factors associated with ocular complications. Results: The overall prevalence of postoperative ocular complications was 8.5% (18/211). A significant association was found between anti-adhesion barrier agent and ocular complications (p=0.020). Conclusions: Anti-adhesion barrier agent used during surgery may be the cause of postoperative ocular complication.

In patients with pleural adhesion, video-assisted thoracic surgery (VATS) has been regarded as a contra- indication. When such adhesions were found during a thoracoscopic trial, the thoracotomy proceeded with for fear of parenchymal Injury and bleeding. We had a question whether or not thoracoscopic surgery should be done in such pleural adhesions. Of the 226 consecutive thoracoscopic surgeries from Jul. 1992 through Sep. 1995, pleural adhesions were detected intraoperatively in 50 cases (22.1%): a detailed breakdown is as follows: pneumothorax (16 cases), pleural disease (15), benign pulmonary nodule(7), mediastinal mass(5), hyperhidrosis (2), diffuse parenchymal or interstitial lung disease (2), bronchiectasis(2), and primary lung cancer(1). We classified pleural adhesions according to their extent and severity. Extent is categorized as the involved area of the lung: degree 1, II, or III; severity is given one of four grades: mild, moderate, severe, or ve y severe. In cases of very severe severity requiring decortication, the possibility of VATS was excluded. Of the 50 cases, mild adhesions were detected in 15 cases(30.0%), moderate in 29 (58.0%), and severe in 6 (12.0%). As for the extent of the adhesions, 8 cases (16.0%) were categorized as degree 1, 32 cases (64. 0%) as degree II, and 10 cases (20.0%) as degree III. For patients with pleural adhesions, the operation time, the chest tube indwelling time, and the postoperative hospital stay were all longer than for patients in the non-adhesion group. Postoperative complications, namely prolonged air-leakage and pleural drain- age, were more common (18.0% and 6.0%, respectively) than in the non-adhesion group (5.1% and 1.7%, respectively). Only two bronchiectatic patients (4%) were converted to an open thoracotomy because of in- ability to control bleeding. Although complications were encountered more frequently in the group with adhesions, patients were still able to enjoy the benefi s of thoracoscopic surgery. It is advisable to proceed with thoracoscopic surgery even in cases of unpredicted pleural adhesions.

In this study, we evaluated effects of three anastomotic techniques of small intestine on adhesions in the dog. Twenty six healthy mixed dogs were randomly assigned to three groups. Group I(n = 8) was sutured with a simple continuous suture, group II(n = 7) was sutured with a simple interrupted approximating suture and group III(n = 11) was sutured with a single layer continuous Connell suture. On completion of any intestinal anastomosis, a pedicle of greater omentum was wrapped around the suture line in all experimental dogs. One percent sodium carboxymeth-ylcellulose (5ml/kg) was administrated into the abdomen by feeding tube prior to closing the last part of peritoneum in all dogs. Postoperative adhesions were evaluated at 14th day after operation. The adhesions consisted primarily in two dogs in group I, three dogs in group II and group III. There were adhesions between intestinal serosal surfaces in eight dogs in all groups, but there were no intestinal serosa-visceral peritoneum adhesion and intestinal serosa-mesentery adhesion. Mean adhesion scores were less than score 2 in all groups. Between anastomotic site and omental graft, there were 13.13$\pm$4.97 mm (mean$\pm$S.D.) adhesion formation in group I and 17.29$\pm$4.68 mm in group II and 14.64$\pm$3.80mm in group III. A simple continuous suture resulted in the least adhesion formation and a simple interrupted approximating suture resulted in the greatest adhesion formation among the groups. However, there were no significant differences among three suture techniques in the severity of adhesions. Intestinal intussusception only encountered in one dog during the 14 days, the dog operated and survived. Daily monitoring of temperature, activity, appetite, defecation and micturition were done. All of those vital signs were within normal values and there were no obvious differences among the groups. In conclusion, even though there were no significant differences among three groups, a simple continous suture pattern is recommended to prevent adhesions when operating intestinal anastomosis in dogs.

This study was performed to determine the effectiveness of poloxamer/sodium alginate mixture(PX/SA) barriers on prevention of post-operative peritoneal adhesion in dogs. Fifteen mongrel dogs were divided into three experimental groups: non-treated group, 2% Sodium Carboxymethylcellulose (SCMC) treated group and PX/SA treated group. In order to induce adhesions, the anti-mesenteric serosa of the ileum was exteriorized and then abraded in a standard manner by scraping with a scalpel blade to create homogeneous petechial hemorrhagic surface over a 1 ${\times}$ 1 cm area. Solution of SCMC was allowed to spread across the intraperitoneal organs through a catheter using a syringe. PX/SA was simply coated over the abraded tissues. On day before and day 1, 4, 7, and 14 after operation, venous blood specimens were collected for measurement of RBC, total WBC and fibrinogen. The adhesions were blindly assessed 3 weeks later by using a computerized tensiometer. The RBC, total WBC and fibrinogen values of three groups showed no statistical significances. The mean tensile strength(gram force, gf) of formed adhesions on day 21 after surgery was 173.05${\pm}$113.48 in the non-treated group, 111.42 ${\pm}$ 38.25 in the SCMC group, and 69.00 ${\pm}$ 45.07 in the PX/SA group. The tensile strength values for adhesion seperation in PX/SA group was lower than those in SCMC group(p < 0.05) and significantly lower than those in the non-treated group(p < 0.05). Our data suggested that PX/SA should be effective on reducing peritoneal adhesion formation in dogs compared with SCMC. PX/SA may be applicable to preventing post-operative intraperitoneal adhesion in dogs.

복강장기의 유착을 방지하기 위하여 토끼의 공장에 인공창상을 일으키고 sodium carboxymethylcellulose (SCMC)와 dextran 70을 단일 혹은 합제로 사용하여 이들의 유착방지 효능을 조사하였고, 아울러 체중의 변화를 조사함으로써 이들을 사용하였을 때 일어날 수 있는 부작용을 검토하였다. 인공창상에 의한 유착형성 유발빈도와 정도를 알아보기 위하여 토끼를 전신마취시킨 다음 개복수술을 시행하여 공장의 장막에 2cm 폭으로 3곳에 abrasion또는 electrocautery를 실시하였던 바, 이러한 인공창상들이 유의성있는 높은 유착형성율(abrasion, 70%; electrocatuery, 72.7%)과 심한 유착정도를 일으켰으며(abrasion, 1.80; electrocatuery, 2.44), 체중의 감소를 가져왔다(abrasion, -2.5%; electrocautery; 9.9%). Abrasion보다는 electrocatuery에 의한 자극이 더욱 심한 유착정도 및 체중감소를 보였으며 심할 경우 폐사를 일으키기도 하였다. 이러한 유착을 효과적으로 방지하기 위하여 1, 2, 3%의 SCMC 및 6, 10%의 dextran 70 용액을 단일 또는 합제를 만들어 abrasion방법으로 공장에 인공창상을 일으킨 토끼의 복강내에 주입하고 수술 4주후에 복강을 열어 유착형성율을 조사하였던 바, 1% SCMC와 10% dextran 70의 합제(Synthetic soln)에서 가장 낮은 유착형성율(0%)을 보여 유착방지 효과가 가장 뚜렸하였다. 아울러 수술 4주일후 체중의 변화도 유의하게 일으키지 아니 하였다. 그러므로 유착방지제로서 synthetic solution을 사용하는 것이 가장 효과적이라고 사려된다.

This study was performed to compare the effect of hyaluronic acid(HA), vitamin I and their combinations for the prevention of postoperative intraperitioneal adhesion in dogs. Twelve mongrel dogs were divided into four groups; HA- (HA Group), vitamin E 800IU- (E8 Group), HA + vitamin E 800IU- (HA+E8 Group) and HA + vitamin E 1600IU-treated group(HA+E16 Group) with three dogs in each group. After celiotomy, five abrasions of 1$\times$1 cm area were made on the antimesenteric serosal surface of the anterior ileocecum with a No. 10 scalpel blade. The five abrasions and peritoneal cavity were coated with 25 of 0.l% HA. Oral supplements of vitamin E were given from the fifth day before the operation to the fourteenth day after the operation. Hematologic values were evaluated before the operation and on the 1st, 4th, 7th and 14th day after the operation. The locations and scores of adhesion were assessed through the second operation on the 21st day after the first operation. The adhesions were located on serosa to mesentary(43.3%)), serosa to serosa(20%), serosa to omentum(5%) and serosa to parietal peritoneum(1.7%). The incidences of adhesion in HA, E8, HA+E8 and HA+E16 groups were 80%, 100%, 47% and 53%, respectively. The scores of adhesion in HA+E8 group(p < 0.05) were lower than those in other groups. This study showed that the combination of HA and vitamin E 800IU was significantly effective in reducing the intraperitoneal adhesion in dogs.
