Sodium hyaluronate carboxymethylcellulose-based bioresorbable membrane (seprafilm™)—Does it affect tumor implantation at abdominal wound sites?

PURPOSE: This study examines the effects of a sodium hyaluronate-based bioresorbable membrane (Seprafilm) on tumor implantation at surgical wound and laparoscopic trocar sites. METHODS: GW-39, an established human colon cancer line carried in immunocompetent golden Syrian hamsters was used as the experimental model. Under general anesthesia, a 2-cm midline incision was made to allow placement of four 5-mm abdominal trocars. Hamsters were then randomly assigned to preSeprafilm, postSeprafilm, and control (no Seprafilm) groups. In the preSeprafilm group 0.5 ml of a 5 percent (vol/vol) suspension of the GW-39 tumor cells (1.675 × 10⁶ cells) was injected into the abdomen of each hamstervia midline incision. Trocars were removed, the wounds were closed, and 1 cm² of Seprafilm was placed on the peritoneal surface of each trocar site. In the postSeprafilm group the membrane was placed at each site before injection of tumor cells. The control group did not receive Seprafilm. The animals were killed after seven weeks, and the abdominal wound sites were excised. Sites without gross tumor underwent histologic evaluation. RESULTS: One hundred thirty-two animals were randomly assigned to the three groups. The preSeprafilm group had an 87 percent tumor implantation rate. The postSeprafilm group had a 90 percent tumor implantation rate. The control group had an 88 percent tumor implantation rate. Chi squared analysis demonstrated that these total tumor implant rates and mean tumor mass were similar at all wound sites and between groups. No toxicity was observed in any of the experimental groups. CONCLUSIONS: Sodium hyaluronate-based bioresorbable membrane (Seprafilm) does not influence GW-39 human colon cancer implantation at abdominal wound sites in this hamster model.Supported in part by an educational grant from Ethicon Endo-Surgery Incorporated, Cincinnati, Ohio, and in part by the Genzyme Corporation, Cambridge, Massachusetts.Read at the meeting of The American Society of Colon and Rectal Surgeons, San Antonio, Texas, May 2 to 7, 1998.     

宫腔镜检查在复发性流产患者诊治中的作用

目的探讨宫腔镜检查在复发性流产(recurrent spontaneous abortion,RSA)患者中的诊治作用。方法 2009年1月至2013年5月对苏州大学附属第二医院就诊的95例RSA患者进行宫腔镜检查,对其检查结果进行分析。结果 95例RSA患者中,子宫腔粘连70例(73.68%),子宫内膜息肉12例(12.63%),子宫腔畸形7例(7.37%),子宫内膜炎3例(3.16%),子宫黏膜下肌瘤1例(1.05%)。研究发现末次流产距就诊时限与宫腔粘连程度有明显相关性(P<0.05),时间间隔越长,宫腔粘连的程度越严重;自然流产次数与宫腔粘连程度没有明显相关性(P>0.05)。结论宫腔镜检查具有直观、操作简单、安全高效、并发症少等优点,在RSA的诊治中具有重要意义。     

Technique of ultrasonic detection and mapping of abdominal wall adhesions

Summary A technique for noninvasive ultrasound examination to detect and map abdominal wall adhesions is described. The examination is based on the demonstration of movement of abdominal viscera during real-time imaging. This movement is called viscera slide and either occurs spontaneously as a result of respiratory movement or may be induced by manual compression. Abdominal wall adhesions produce a restriction of viscera slide. Ultrasonic demonstration of restricted viscera slide has been used for the precise localization and mapping of abdominal wall adhesions prior to abdominal surgery. The technique may be particularly useful in providing safe initial access in patients undergoing laparoscopy who are at increased risk for trocar injury of viscera due to abdominal wall adhesions resulting from previous surgery or peritonitis.     

Inflammation of the visceral pleura, a nonspecific asbestos-related pleural reaction: chest radiograph and computed tomograph correlation

Nonspecific pleuritis, i.e., inflammation of the visceral pleura, is recognized by the presence of pleural strands on the routine posteroanterior chest radiograph. The computed tomograph counterparts of these strands are seen as interlobular septal intrusions and lenticular or wedge-shaped subpleural opacities. The pleural reaction is nonspecific and may be found with asbestos exposure, traumatic hemorrhagic effusions, pulmonary embolism, viral pleurisy, malignant pleural effusions, and lupus or rheumatoid effusions. The asbestos-related pleural changes may be found alone or in association with parietal pleural plaque formation or with asbestotic lung fibrosis.     

Ultrasonic detection of viscera slide as an indicator of abdominal wall adhesions.

Real-time ultrasonography can detect the movement of viscera immediately deep to the abdominal wall. This motion of abdominal contents is called viscera slide, and is produced by the force of respiratory motion (spontaneous viscera slide) or by manual ballottement of the abdomen (induced viscera slide). Viscera slide was observed in 18 "normal" subjects (no history of previous abdominal surgery or peritonitis) and in 24 subjects at "risk" for abdominal wall adhesions because of previous abdominal operations or past history of peritonitis. In 14 of the 24 "risk" group subjects, spontaneous and induced viscera slide was restricted to excursions of less than 1 cm (58.3%). Operations were performed on 18 patients, which confirmed the fact that restriction of ultrasonically detected viscera slide identified abdominal wall adhesions in all cases, but no adhesions were found in patients with normal viscera slide. This ultrasonic finding of restricted viscera slide may be useful in the preoperative discovery and localization of abdominal wall adhesions prior to laparoscopy or laparotomy.
