Mesh fixation with human fibrin glue (Tissucol) in open tension-free inguinal hernia repair: a preliminary report

Background: The Lichtenstein technique for inguinal hernia repair is easy to learn and associated with few complications. However, recent studies have suggested that this technique is inferior to some ‘sutureless’ repair systems in terms of perceived difficulty, operating time, surgeon satisfaction, etc. Methods: We employed a sutureless Lichtenstein technique in 80 consecutive patients with primary unilateral inguinal hernia, to assess patient and trainee surgeon outcomes. Human fibrin glue was used in place of conventional sutures. Results: The mean operating time was 36 min and all patients were discharged 5–6 h after the operation. On a 100-point visual analogue scale, the surgeons rated the difficulty of the operation as low (mean score, 31), and perceived satisfaction as high (mean score, 84). No complications were observed at 12-month follow-up. Conclusion: This study confirms the efficacy of mesh fixation with human fibrin glue, and supports the viability of a sutureless Lichtenstein procedure.

Serum IgA and IgG functional antibodies and their subclasses to Streptococcus pneumoniae capsular antigen found in two aged‐matched cohorts of children with and without otitis media with effusion

Serum IgA and IgG functional antibodies and their subclasses to Streptococcus pneumoniae capsular antigen found in two aged‐matched cohorts of children with and without otitis media with effusion The relationship between acute otitis media and otitis media with effusion (OME) is uncertain and the aetiology of OME is multifactorial. Otitis media with effusion may be an inflammatory condition; both bacteria and viral infections could play a part in this inflammation. The four bacteria Streptococcus pneumoniae, Haemophilus influenza, Staphylococcus aureus and Branhamella catarrhalis cause 60% of the infections whereas S. pneumoniae accounts for up to 35%. IgA provides the dominant surface response to polysaccharide and lipopolysaccharide antigens, of which IgA₂ is the main subclass. Once the mucosa has been breached, most protection is provided by IgG. IgG₂ acts mainly against bacterial capsular antigens. This study looked at two groups of 50 children with and without OME who were aged between 3 and 10 years. The aims were to determine if, firstly, the levels of the serum immunoglobulins were different in the two groups, secondly whether these children made the appropriate antibody response to the capsular antigen to S. pneumoniae (PCP), and finally if there was a delay in the maturity of the IgA response. The total IgG, IgA and all subclass levels were measured using radial immunodiffusion. Levels of functional IgA and IgG were measured using ELISAs (25 patients in each group). The results were analysed with non‐parametric tests. The immunoglobulin levels were within the normal levels for both groups. There were very good correlations between the IgG total anti‐PCP and the IgG₂ anti‐PCP (R > 0.9, p = 0.001). There was a good correlation between the levels of both IgG total and IgG₂ anti‐PCP against IgA total anti‐PCP in both groups (R > 0.85, p > 0.01). This confirms a normal antibody response between both groups of patients. The ages of the controls and patients (50 samples) were correlated with increasing titres of circulating functional antibodies (P = 0.001). This is highly suggestive of a normal age‐related response. In conclusion, the findings were contradictory to our original hypothesis that there is a subtle difference in surface protection between children with and without OME. We believe that a previous history of recurrent acute otitis media is unrelated to the development of OME after 3 years of age.     

A comparison of glue and a tube as an anastomotic agent to repair the divided buccal branch of the rat facial nerve

The best anastomotic agent to join nerve ends is controversial. This paper describes a controlled trial between a collagen tube wrap and a tissue glue to anastomose the rat facial nerve. There was no difference in the results using photographic, histological and electrophysiological techniques.     

TH胶胃冠状静脉栓塞术治疗门脉高压症

11例TH胶胃冠状静脉栓塞术临床治疗结果表明:(1)11例中的4例急性上消化道大出血患者均在12h左右出血基本停止,随访近一年未再发生出血现象。(2)10例半年后复查肝功能均有不同程度改善。(3)一年后复查食道钡餐透视X线平片发现8例患者食道静脉曲张有不同程度减轻。(4)11例中1例因术中急性肝功能衰竭死亡。因此我们认为此术式操作简便,手术创伤小、较易推广,是治疗门脉高压症合并食管胃底静脉曲张出血的一种有效方法。

目的　探讨医用创面封闭胶在减少肝切除术后肝断面渗血中的价值。方法　 2 0 0 2年 5～ 11月采用信封法将 60例接受肝切除术的病人随机分为医用胶组 (A组 ,n =3 0 )和对照组 (B组 ,n =3 0 )。A组在肝断面彻底止血后滴注医用创面封闭胶 ,B组则不用。测定术后第 1、2、3d腹腔引流液中红细胞 (RBC)数和血红蛋白 (Hb)量。结果　A、B两组术后腹腔引流液中的RBC数和Hb量均以第 1d为高峰 ,显著高于第 2、3d(P <0 0 5) ,其中A组术后第 1d腹腔引流液中RBC数及Hb量均显著低于B组 (P <0 0 5) ,只相当于B组第 2d的水平。A组主要并发症发生率低于B组 ,但差异无统计学意义 (P =0 0 7)。结论　医用创面封闭胶可有效抑制肝切除术后早期的肝断面渗血 ,有助于降低术后并发症的发生率
