Review
This article focuses on the cross-sectional imaging spectrum of abnormalities that affect the abdominal wall, with emphasis on magnetic resonance imaging (MRI). Cross-sectional imaging is valuable for diagnosing and evaluating the extent of abdominal-wall masses. With the increasing use of MRI, it is often possible to reach a diagnosis or narrow the differential diagnosis, thereby guiding effective management. Neoplastic and non-neoplastic pathologies will be illustrated, and the distinctive imaging characteristics of these entities will be highlighted.

Review
Diastasis of the rectus abdominis muscles (rectus diastasis, RD) is common, particularly in postpartum women. Although imaging is not always mandatory for assessment, several cross-sectional imaging techniques, in particular ultrasound (US), computed tomography (CT) and magnetic resonance imaging (MRI) can depict the abdominal wall in exquisite detail. They permit simultaneous assessment of the degree and craniocaudal extent of RD, evaluation for co-existent hernia and subjective judgement of muscle quality. Increasingly, dynamic imaging techniques show both static anatomy and muscle movement and function. In this review, we highlight the imaging findings of RD, associated hernia, and potential mimics.

Negative pressure wound therapy (NPWT) is widely known in surgical practice. The initial indications for NPWT were chronic wounds, especially diabetic foot, vascular and decubitus ulcers, and infected traumatic wounds. Nowadays, the use has been widely increased. Although in the field of abdominal wall surgery, it has mainly been used in the treatment of surgical wound complications after hernia repair, other indications have been added after years of experience in the management of NPWT. Therefore, the aim of this article is to analyze and review the main indications of NPWT in abdominal wall surgery, as well as the advantages obtained with its application.

Review
BACKGROUND
Neuroendocrine tumors (NETs) are neoplasms that arise from cells of the endocrine and nervous system. NETs, often found in the gastrointestinal tract, can be found anywhere in the body, and have metastatic potential. NETs occasionally present with metastatic disease without an identifiable primary tumor.
CASE
A 79-year-old female patient presented with an abdominal wall mass. Percutaneous biopsy was consistent with a NET. Preoperative endoscopy and PillCam were unremarkable. PET Dotatate demonstrated uptake in the abdominal wall as well as vague uptake in the pelvis. Intraoperatively, we identified a suspicious nodule on the sigmoid colon, which was consistent with a drop metastasis on final pathology.
CONCLUSION
In this case report we present a patient with a NET metastasis to the abdominal wall without a known primary site. This case highlights the limitations of endoscopy and imaging in the workup of metastatic NETs. Additionally, this is a novel case report of a metastatic NET to the abdominal wall without an identifiable primary site.

Review
Ventral hernias represent the most common complication after abdominal surgery. Loss of domain and/or large ventral hernias in patients are especially challenging for surgeons to manage, but preoperative image-guided botulinum toxin injection has emerged as an effective adjunct to abdominal wall surgery. Loss of domain is caused by chronic muscle retraction of the lateral abdominal wall and leads to an irreducible protrusion of abdominal viscera into the hernia sac. Botulinum toxin can be used in the oblique muscles as a chemical component relaxation technique to aid abdominal wall reconstruction. Intramuscular botulinum toxin injection causes functional denervation by blocking neurotransmitter acetylcholine release resulting in flaccid paralysis and elongation of lateral abdominal wall muscles, increasing the rate of fascial closure during abdominal wall reconstruction, and decreasing recurrence rates. In total, 200-300 units of onabotulinumtoxinA (Botox®) or 500 units of abobotulinumtoxinA (Dypsort®) in a 2:1 dilution with normal saline is most commonly used. Botulinum toxin can be injected with ultrasonographic, EMG, or CT guidance. Injection should be performed at least 2 weeks prior to abdominal wall reconstruction, for maximal effect during surgery. At minimum, botulinum toxin should be injected into the external and internal oblique muscles at three separate sites bilaterally for a total of six injections. Although botulinum toxin use for abdominal wall reconstruction is currently not indicated by the Food and Drug Administration, it is safe with only minor complications reported in literature.

Review
This work reports the second part of a review on synthetic surgical meshes used for abdominal hernia repair. While material and structural characteristics, together with mesh-tissue interaction, were considered in a previous article (Part I), biomechanical behavior is described here in more detail. The role of the prosthesis is to strengthen the impaired abdominal wall, mimicking autologous tissue without reducing its compliance. Consequently, mesh mechanical properties play a crucial role in a successful surgical repair. The main available techniques for mechanical testing, such as uniaxial and biaxial tensile testing, ball burst, suture retention strength, and tear resistance testing, are described in depth. Among these methods, the biaxial tensile test is the one that can more faithfully reproduce the physiological loading condition. An outline of the most significant results documented in the literature is reported, showing the variety of data on mesh mechanical properties. Synthetic surgical meshes generally follow a non-linear stress-strain behavior, with mechanical characteristics dependant on test direction due to mesh anisotropy. Ex-vivo tests revealed an increased stiffness in mesh explants due to the gradual ingrowth of the host tissue after implant. In general, the absence of standardization in test methods and terminology makes it difficult to compare results from different studies. Numerical models of the abdominal wall interacting with surgical meshes were also discussed representing a potential tool for the selection of suitable prostheses. © 2016 Wiley Periodicals, Inc.

Review
Compared with conventional ventral hernia repair, there are several additional considerations germane to the oncologic abdominal wall reconstruction, including the management of radiation soft-tissue injury, the management of bacterial contamination, and the location and extent of the defect. Herein, we review some of the unique challenges associated with oncologic abdominal wall reconstruction and introduce a new classification schema to assist the reconstructive surgeon in performing these complex cases.

Abdominal wall endometriosis is a rare disease that usually develops in association with a cesarean section scar. Although frequently identified in the skin and subcutaneous adipose tissue adjacent to the cesarean scar, intramuscular localization is possible but rare. Treatment is based on surgical excision of the lesion associated with or without hormone therapy. Wide surgical excision is the treatment of choice, but it exposes to the risk of abdominal wall hernia. We here report two cases of parietal endometriosis occurring after Pfannstiel scar for cesarean section whose data were collected at the Department of surgery in the Zaghouan Regional Hospital.
