Traumatic abdominal wall hernia caused by a low fall.

ABSTRACT:

Background

Traumatic abdominal wall hernias (TAWH) are uncommon injuries classically associated with high-energy blunt traumatic mechanisms. Motor vehicle collisions cause the highest proportion of all TAWH. Literature is currently limited, with some debate existing over surgical management strategies.

Case presentation

A 67-year-old man presented after falling from a short step stool while landscaping his yard. On exam, an exquisitely tender lateral flank mass was present with peristaltic movement. CT imaging revealed a TAWH with incarcerated large and small bowel. He was taken to the OR for exploratory laparotomy and mesh hernia repair. The patient was discharged on the third postoperative day with no untoward complications.

Discussion

This patient's mechanism and injury pattern are together a rare combination. Exam findings and radiologic technologies are used to hone the clinical index of suspicion for TAWH. Traumatic abdominal wall defects can have unusual anatomic borders, not always obeying well-known hernia patterns. In this case, the potential space for visceral herniation was created by an 11th rib fracture with associated avulsion of the oblique musculature. Operative approach can be open or laparoscopic, however concomitant injuries directly influence surgical management. Evidence for mesh versus primary repair for TAWH is conflicted by the current literature.

Conclusions

Nearly any amount of blunt abdominal force can cause TAWH. For wall defects with bowel herniation caused directly by trauma, the safest approach may involve exploratory laparotomy. Future multi-center studies may be able to distinguish TAWH repair strategies based on herniation through old defects versus newly-created abdominal wall injuries.

Project description:ObjectiveAbdominal wall hernias are common abdominal diseases, and effective hernia repair is challenging. In clinical practice, synthetic meshes are widely applied for repairing abdominal wall hernias. However, postoperative complications, such as inflammation and adhesion, are prevalent. Although biological meshes can solve this problem to a certain extent, they face the problems of heterogeneity, rapid degradation rate, ordinary mechanical properties, and high-cost. Here, a novel electrospinning mesh composed of polylactic acid and silk fibroin (PLA-SF) for repairing abdominal wall hernias was manufactured with good physical properties, biocompatibility and low production cost.Materials and methodsFTIR and EDS were used to demonstrate that the PLA-SF mesh was successfully synthesized. The physicochemical properties of PLA-SF were detected by swelling experiments and in vitro degradation experiments. The water contact angle reflected the hydrophilicity, and the stress‒strain curve reflected the mechanical properties. A rat abdominal wall hernia model was established to observe degradation, adhesion, and inflammation in vivo. In vitro cell mesh culture experiments were used to detect cytocompatibility and search for affected biochemical pathways.ResultsThe PLA-SF mesh was successfully synthesized and did not swell or degrade over time in vitro. It had a high hydrophilicity and strength. The PLA-SF mesh significantly reduced abdominal inflammation and inhibited adhesion formation in rat models. The in vitro degradation rate of the PLA-SF mesh was slower than that of tissue remodeling. Coculture experiments suggested that the PLA-SF mesh reduced the expression of inflammatory factors secreted by fibroblasts and promoted fibroblast proliferation through the TGF-β1/Smad pathway.ConclusionThe PLA-SF mesh had excellent physicochemical properties and biocompatibility, promoted hernia repair of the rat abdominal wall, and reduced postoperative inflammation and adhesion. It is a promising mesh and has potential for clinical application.

Project description:IntroductionQuality of Life (QoL) is an important consideration in patients with abdominal wall hernia (AWH). What matters to patients and their everyday experience living with AWH may depend on a variety of personal, psychological, social and environmental factors. At present, no study has addressed what is important to this particular group of patients by asking the patients themselves. This study aims to determine QoL from the patient's perspective by examining the lived experience in this patient population.MethodsWe interviewed 15 patients with AWH until thematic saturation. The patients were purposively sampled from AWH clinic between February 2020 and June 2020 using topic guides and interview schedules. Verbatim interview transcripts were coded and analysed using NVivo12 software and Interpretative Phenomenological Analysis (IPA). We adhered to consolidated criteria for reporting qualitative research (COREQ).ResultsFifteen participants (8 men and 7 women) of age range 36-85 years, median 65 years, covering all Ventral Hernia Working Group (VHWG) grades. Five superordinate themes were identified each with several subordinate themes, as follows: (1) body image (subthemes-'changes to perceptions of self' and 'fears concerning perceptions of others'). (2) Mental health (subthemes-'emotional responses', 'disruptions to previously solid aspects of identity', 'developing coping strategies'). (3) Symptoms (subthemes-'managing pain', 'freedom of movement', 'restriction and adaptation of function'). (4) Interpersonal relationships (subthemes-'difficulties socially connecting' and 'changes in sexual relations'). (5) Employment (subthemes-'financial pressure', 'return to work issues' and 'costs to family').ConclusionThis is the first phenomenological qualitative study in the field of AWH and presents a rich account of what is important to these patients in terms of QoL. Developed from the patients' own words, the themes are interrelated and should shape our understanding of patients with AWH. This study provides qualitative examples of each theme. This study has identified new themes (body image, interpersonal relationships and employment) that are not incorporated in existing AWH-specific QoL instruments. This is important for surgeons because the study suggests that we are currently not capturing all data relevant to QoL in this specific patient group with current tools. The wider impact of this would be to help counsel patients and support them more holistically through the disease process and it's management. Further research is needed to generate a standardised AWH QoL instrument which incorporates bio-psycho-emotional-social themes important to patients, as identified by patients.
