[Abdominal pseudohernia: diagnosis and treatment]

To present an effective treatment strategy for abdominal pseudohernia considering own clinical experience and literature data.

The authors report surgical treatment of 2 patients and therapeutic management of 1 patient with abdominal pseudohernia. Moreover, current state of this problem is analyzed according to literature data in Pubmed, Google and e-library databases.

Seudohernia is followed by asymmetrical protrusion of abdominal wall, prolapsed site is not involved in breathing; patients cannot tense muscles in the affected area. T8-L2 skin sensitivity impairment or hyperesthesia may be observed. Denervation is confirmed by electroneuromyography. Ultrasound, CT and MRI reveal no defect in abdominal wall. However, its thinning within denervation area is visualized. Treatment is determined by the cause and reversibility of denervation. If mechanical damage (intersection) of T8-L2 nerves following trauma or any manipulation is absent, the main cause is herpes zoster neuropathy. Surgical treatment is not indicated. Antiherpetic therapy and physical therapy result functional restoration of abdominal wall muscles within 2-4 months. In case of mechanical cause of pseudohernia, it is advisable to wait at least a year after denervation for real assessment of situation. Partial or complete re-innervation is possible throughout this period. Surgical treatment is indicated if re-innervation is absent. An effective technique presented in this manuscript is reconstruction of the prolapsed area with several imbrication sutures in several planes up to symmetry with contralateral area with subsequent reinforcement with a mesh implant if necessary. There were no relapses in 2 our patients within 5 and 7 years, respectively.

In our opinion, this report is the first manuscript devoted to systematic analysis of diagnosis and treatment of abdominal pseudohernia in available literature. Surgical treatment is not indicated for postherpetic pseudohernia. It is carried out for pseudohernia persisting for more than 1 year if its cause is trauma or any manipulation.
