The concern with posterior rectopexy is that of denervation. There is a small risk of damage to the sympathetic nerves, which in turn may risk ejaculatory problems. The parasympathetic nerves, by contrast, are less at risk with the posterior dissection, as there is little need to perform extensive dissection in the region of Denonvillier’s fascia. The issue of the lateral ligaments has also aroused interest, as some authors describe these as discrete structures lying lateral to the rectum and containing both the middle rectal arteries and parasympathetic nerves, though it is noteworthy that others do not believe them to be discrete structures.97 Preservation of these lateral ligaments was assessed by Speakman et al.98 in a randomised trial that examined Marlex posterior rectopexy. In essence, this trial showed that preservation of the ligaments was associated with a lower rate of constipation but a higher recurrence rate. These results are summarised in Table 20.23.

In 2010, osterguArd discussed the importAnce of different mesh properties to include density, pore size, elAsticity, filAment size, surfAce AreA, And overAll mesh loAd (tAble 87.1) [41,42]. He Also discussed potentiAl mesh-relAted complicAtions to include erosion And exposure, dyspAreuniA, And pelvic pAin. Due to these bAsic mesh-relAted principles And complicAtions, multiple studies hAve been performed focusing on mesh loAd, durAbility, And complicAtions AssociAted with mesh plAcement. Multiple studies hAve Also been performed compAring nAtive tissue mesh And the trAditionAl polypropylene mesh outcomes.

Tracheomalacia: Functional Imaging of the Large Airways with Multidetector-Row CT

Regarding morphology, one should describe whether the collapse occurs circumferentially, or if it occurs primarily due to either excessive bulging of the posterior membranous wall or collapse of the anterolateral cartilaginous structures. For example, patients with collapse primarily due to bulging and flaccidity of the posterior membranous wall are potential candidates for tracheoplasty surgery, a novel surgical technique in which in the posterior wall of the trachea is reinforced by a Marlex graft (26). Surgical reinforcement of the posterior membranous wall enhances the rigidity of this structure and makes it less susceptible to bowing during expiration.
Ectopia Cordis: 6-Year Survival without Surgical Correction
Published in Fetal and Pediatric Pathology, 2021
Nevertheless, the overall surgical objective of EC (all varieties) management includes closure of the chest wall defect, either by primary chest wall closure or by using bone/cartilage as tissue graft or artificial prosthesis like acrylic plaques or marlex mesh. The complete encasement of the ectopic heart with no other recognizable malformation may have allowed the survival of this child.
