Novel large-pore lightweight polypropylene mesh has better biocompatibility for rat model of hernia.

Novel large-pore lightweight polypropylene mesh has better biocompatibility for rat model of hernia. J Biomed Mater Res A. 2018 Jan 03;: Authors: Qiu W, Zhong C, Xu R, Zou T, Wang F, Fan Y, Wang L, Yang Z Abstract PURPOSE: Abdominal wall hernias are repaired with tension-free prosthetic materials but there remains a foreign body response (FBR) to commonly used polypropylene mesh. Thus, we should optimize mesh materials to improve the patient outcomes after surgery. MATERIALS AND METHODS: A polypropylene mesh was developed with wrap knitting technique. The physical, mechanical and biocompatible characteristics were tested in a rat abdominal hernia model and compared to ULTRAPRO and Easy Prosthesis. RESULTS: Polypropylene mesh of two pore sizes was developed (LP-WKPM and SP-WKPM). Compared with ULTRAPRO and Easy Prosthesis mesh, the novel mesh were lighter, thinner, and stronger (p

We present a case of a 60-year-old male patient presented with bilateral inguinal swelling associated with urinary hesitancy and intermittency. He had undergone transabdominal preperitoneal (TAPP) repair for a left inguinal hernia 8 years ago. CT scan confirmed the presence of a bilateral hernia with the bladder herniating bilaterally. He underwent an elective bilateral open Lichtenstein tension-free mesh repair.

ConclusionThe plan of care for patients with acutely symptomatic hernias discharged from the ED depends on outpatient follow-up, but more than 50% of patients are lost to follow-up, and nearly 1 in 5 return to the ED. The uninsured are at particularly high risk.

ConclusionA high number of patients present emergently for groin hernia repair at a county hospital in Guatemala compared to developed countries. Our data suggest that emergent hernias are likely the result of patient-related issues rather than health care system limitations.

AbstractObjectiveIn this systematic review, we evaluated all literature reporting on the surgical treatment of primary epigastric hernias, primarily focusing on studies comparing laparoscopic and open repair, and mesh reinforcement and suture repair.MethodsA literature search was conducted in Embase.com, PubMed and the Cochrane Library up to 24 April 2019. This review explicitly excluded literature on incisional hernias, ventral hernias not otherwise specified, and isolated (para)umbilical hernias. Primary outcome measures of interest were early and late postoperative complications.ResultsWe  obtained a total of ...

AbstractForamen of Winslow hernia (FWH) is an extremely rare entity accounting for up to 8% of internal hernias and 0.08% of all hernias. Only 150 cases of FWH have been described in the literature to date with a peak incidence between the third and sixth decades of life. Three main mechanisms seem to be implicated in the FWH pathogenesis: (a) excessive viscera mobility, (b) abnormal enlargement of the foramen of Winslow, and (c) changes in the intra-abdominal pressure. The presence of an abnormally long bowel, enlargement of the right liver lobe or cholecystectomy, a “wandering cecum,” and defects of the gastr...

CONCLUSIONS: Mesh repair for all hernia types is more common than suture repair. However, for umbilical and other abdominal wall hernias, a significant proportion are repaired without the use of mesh. PMID: 31418302 [PubMed - as supplied by publisher]

Fundoplication is performed routinely during laparoscopic repairs of a paraesophageal hernia, but the degree of fundoplication remains controversial. The purpose of this study is to assess postoperative dysphagia and reflux after a Dor versus a Nissen fundoplication in patients undergoing laparoscopic repair of giant paraesophageal hernias.

ConclusionsEmergency repair of complicated abdominal hernias remains one of the most common and challenging surgical emergencies worldwide. WSES aims to provide an essential version of the evidence-based guidelines focusing on the timing of intervention, laparoscopic approach, surgical repair following the Centers for Disease Control and Prevention (CDC) wound classification, antimicrobial prophylaxis and anesthesia in the emergency setting.

ConclusionsUse of different surgical approaches and types of repair for primary presentations of femoral hernia did not affect the recurrence rate or time to recurrence. Use of a pre-peritoneal mesh did not alter the recurrence rate or recurrence free survival, in either elective or emergency settings, compared to simple suture repair. Recurrence following primary femoral hernia repair tends to occur within the first post-operative year, suggesting that technical factors may be as important as suture or mesh failure.

CONCLUSION: Surgeons must work with the implant that best suits their patients' needs and that also provides good results and adequate working comfort. The PUMP technique performs well for ventral hernias sized between 2 and 4 cm without the need of midline reconstruction due to diastasis of the rectus muscles. It enables a local extraperitoneal mesh augmentation without the risk of intraperitoneal complications. PUMP repair lowers the risk of recurrence in comparison with suture repair without increasing the risk of complications. PMID: 31394581 [PubMed - as supplied by publisher]
