Incisional hernia—comparison of mesh repair with Cardiff repair: an university hospital experience

Background: Incisional hernia is a frequent complication of abdominal surgery. Various types of repair are recommended for incisional hernia. Suture and mesh repair are compared in the present study. Method: One hundred seventy one patients with incisional hernia underwent Cardiff repair (far and near sutures with reinforcement sutures) which was used as an open suture repair while onlay polypropylene mesh was used in the mesh repair technique. Result: Cardiff repair was performed in 116 patients with no mortality with recurrence in two patients with mean follow up of 7.1 years. Both these patients with recurrence had a defect measuring more than 10 cm in width. Mesh repair was carried out in 55 patients with no recurrence in mean follow up of 37 months. Seroma formation was noted in 7 (12.72%) with mesh repair as compared to 4 (3.44%) patients with Cardiff repair. Conclusion: We recommend Cardiff repair for primary and small to medium size incisional hernias. Onlay polypropylene mesh is ideal for tension-free hernia repair, recurrent incisional hernia and hernia defects wider than 10 cm.

Management of mesh complications and vaginal constriction: a urogynecology perspective

Once thought of as a long-term solution to pelvic organ prolapse, currently synthetic mesh augmentation is regarded as a dark area that is being critically assessed by surgeons, hospitals, industry, and most importantly the Food and Drug Administration. The development of midurethral sling kits has revolutionized the surgical treatment of stress incontinence. These systems, however, were not rigorously tested but instead marketed after being cleared by the Food and Drug Administration through a simple regulatory process using a previously approved predescent material. This article reviews the management of mesh complications of synthetic slings and mesh used to augment prolapse repair.     

补片修补造口旁疝38例疗效

目的总结造口旁疝应用Keyhole补片及超普平片进行疝修补术的疗效。 方法回顾性分析2005年1月至2018年4月,上海交通大学附属第六人民医院采用Keyhole补片及超普平片对38例造口旁疝患者行疝修补术治疗的临床资料。 结果38例造口旁疝患者均采用置入补片的疝修补术实施修补。其中15例行开放手术,6例行纯腔镜下腹膜内补片植入手术,5例行开放结合腔镜的杂交手术,12例行Lap-re-Do手术。手术时间40～300 min,平均（150±72）min。全部随访时间2～46个月,其中造口旁疝复发2例（缝合疝环、补片加固）,浆液肿4例,切口感染3例,造口肠管血运轻度障碍1例,均处理痊愈。 结论造口旁疝应积极应用补片行疝修补手术,疗效可靠。术式需根据术前仔细评估和术中情况做相应选择。     

Late complication of open inguinal hernia repair: Small bowel obstruction caused by intraperitoneal mesh migration

We describe a case of small bowel obstruction due to prosthetic mesh migration. A 67-year-old male, who had undergone prosthetic repair of inguinal hernia 3 years before, was admitted for a mechanical small bowel obstruction. Laparotomy revealed the penultimate ileal loop choked by an adhesion drawing it towards a polypropylene mesh, firmly attached to the parietal peritoneum of the inguinal region. The intestinal loop was released; the mesh was embedded deep with continuous whip suture after folding the parietal peritoneum. The patient was dismissed on the 11th postoperative day surgically healed. The "tension-free" technique is undoubtedly the gold standard for hernia repair. However, it is not free of complications, mostly due to technical errors, of which the surgeon must be aware, both when he is responsible for correcting defects in the wall, as well as when he has to face an occlusion in a patient who has undergone plastic surgery for inguinal hernia.     

裁剪式双层prolene网片在老年腹股沟疝无张力修补术中的应用

目的 探讨裁剪式双层prolene网片在老年腹股沟疝无张力修补术中的临床应用价值。方法 对1997年7月至2005年7月应用裁剪式双层prolene网片行老年腹股沟疝无张力修补术56例的临床资料进行回顾性分析。结果 56例中，原发性腹股沟疝19例（33．9％），复发性腹股沟疝37例（66．1％）。巨大疝环12例（21．4％），伴发其他疾病44例（78．6％）。并发症发生率为10．7％（6／56）。平均手术时间45min；平均住院3．2d；随访6个月至8年，无术后复发。结论 应用裁剪式双层prolene网片进行腹股沟疝无张力修补术，符合老年腹股沟疝的解剖特点和“个体化”要求，尤其适合于老年巨大疝环者或复发性疝。由于操作简便、安全和经济等特点，易于广泛推广。

Resistance to adhesion formation: A comparative study of treated and untreated mesh products placed in the abdominal cavity

Background: New materials have been devised to prevent postoperative adhesions when placing a prosthesis in contact with abdominal contents. Methods: Eighty rats underwent laparotomy and denudation of the serosa of the cecum and peritoneal covering of the abdominal wall. Five treated mesh products (Parietex Composite, Parietene Composite, Bard Composix E/X, Sepramesh, and Gore-Tex Dual Mesh) and one untreated mesh product (untreated Parietene) were randomly placed between the cecum and abdominal wall. A group without mesh was used as control. The animals were sacrificed at 21 days following surgery and analyzed for the presence of adhesions.Results: The incidence of adhesion formation, mean adhesion area, maximum adhesion length, and strength of adhesion separation were similar between Parietex Composite, Parietene Composite, and Bard Composix E/X, and they were significantly less than with Sepramesh, untreated Parietene, and the control group. Gore-Tex Dual Mesh resulted in less adhesions, adhesion area, mean strength of separation, and work of separation than the untreated Parietene group and the control group. Sepramesh resulted in less strength and work of separation compared to the control group. Conclusions: The incidence of adhesions and work and strength of adhesion separation are reduced when using a treated mesh, compared to the untreated mesh and the control group without mesh. Parietex Composite, Parietene Composite, Bard Composix E/X, and Gore-Tex Dual Mesh were superior to Sepramesh, untreated Parietene, and the control group in the prevention of adhesion formation.Disclosure statement: This study was sponsored by: Sofradim, Trévoux, France     

Rotator cuff repair with a novel mesh suture: An ex vivo assessment of mechanical properties

Surgical repair is a common treatment for rotator cuff tear; however, the retear rate is high. A high degree of suture repair strength is important to ensure rotator cuff integrity for healing. The purpose of this study was to compare the mechanical performance of rotator cuffs repaired with a mesh suture versus traditional polydioxanone suture II and FiberWire sutures in a canine in vitro model. Seventy‐two canine shoulders were harvested. An infraspinatus tendon tear was created in each shoulder. Two suture techniques—simple interrupted sutures and two‐row suture bridge—were used to reconnect the infraspinatus tendon to the greater tuberosity, using three different suture types: Mesh suture, polydioxanone suture II, or FiberWire. Shoulders were loaded to failure under displacement control at a rate of 20 mm/min. Failure load was compared between suture types and techniques. Ultimate failure load was significantly higher in the specimens repaired with mesh suture than with polydioxanone suture II or FiberWire, regardless of suture technique. There was no significant difference in stiffness among the six groups, with the exception that FiberWire repairs were stiffer than polydioxanone suture II repairs with the simple interrupted technique. All specimens failed by suture pull‐out from the tendon. Based on our biomechanical findings, rotator cuff repair with the mesh suture might provide superior initial strength against failure compared with the traditional polydioxanone suture II or FiberWire sutures. Use of the mesh suture may provide increased initial fixation strength and decrease gap formation, which could result in improved healing and lower re‐tear rates following rotator cuff repair. © 2017 Orthopaedic Research Society.

Comparison of the adherence of <Emphasis Type="Italic">E.Coli</Emphasis> and <Emphasis Type="Italic">S. Aureus</Emphasis> to ten different prosthetic mesh grafts: <Emphasis Type="Italic">In vitro</Emphasis> experimental study

Background  

The prosthetic mesh grafts used to repair the abdominal wall may become infected, primarily by S. aureus and E. coli. This study sought to provide a rational basis for the choice of mesh used to repair a hernia when there is a likelihood of infection or contamination.
