Extraosseous Ewing’s tumor of lateral abdominal wall

The abdominal expansion (AE) strategy, involving eccentric contraction of the abdominal muscles, has been increasingly used in clinical practices; however, its effects have not been rigorously investigated. This study aimed to investigate the immediate effects of the AE versus abdominal drawing-in (AD) strategy on lumbar stabilization muscles in people with nonspecific low back pain (LBP). Thirty adults with nonspecific LBP performed the AE, AD, and natural breathing (NB) strategies in three different body positions. Ultrasonography and surface electromyography (EMG) were, respectively, used to measure the thickness and activity of the lumbar multifidus and lateral abdominal wall muscles. The AE and AD strategies showed similar effects, producing higher EMG activity in the lumbar multifidus and lateral abdominal wall muscles when compared with the NB strategy. All muscles showed higher EMG activity in the quiet and single leg standing positions than in the lying position. Although the AE and AD strategies had similar effects on the thickness change of the lumbar multifidus muscle, the results of thickness changes of the lateral abdominal muscles were relatively inconsistent. The AE strategy may be used as an alternative method to facilitate co-contraction of lumbar stabilization muscles and improve spinal stability in people with nonspecific LBP.

Background The abdominal wall expanding system (AWEX) was first applied in 2012 and published in 2017. This novel technique was developed to reconstruct complex incisional hernias and residual skin-grafted laparostoma after treatment of an open abdomen, when primary midline closure was impossible. The main aim was the anatomical reconstruction of the abdominal wall and the avoidance of dissecting techniques (component separation). Methods Between 2012 and 2019, 33 patients underwent AWEX hernia repair in three certified hernia centers. The retracted abdominal wall was stretched with the AWEX system intraoperatively for approximately 30 min. Hernia size was measured preoperatively, on CT, and intraoperatively. The gain in length on the lateral abdominal wall (decrease in width of the defect) after stretching and any residual midline gap were determined in the OR. Results 33 patients underwent AWEX procedures. Six cases were evaluated separately because of additional procedures (TAR, four cases) and preoperative application of botulinum toxin (two cases). The median (95% confidence interval) measured width of hernia defects was 13 (12–16) cm, the median gain in length on the lateral abdominal wall was 12 (10–15) cm. After median follow-up of 29 (12–54) months, one recurrence from the broken mesh was observed. No method-related complications occurred. Conclusion Based on the 2017 and current results, the AWEX system represents an alternative or supplemental procedure to current techniques for complex abdominal wall reconstruction. The system proved again to be time-saving, safe, effective, and easy to learn. Further studies with enhanced technology are in progress.

Lateral Abdominal Wall

Thoracoabdominal hernias are uncommon following blunt trauma. If diaphragmatic rupture does occur, the abdominal viscera can herniate into the thorax through the diaphragm. We report a rare case of thoracoabdominal herniation in which the bowel herniated through the lateral abdominal wall, migrating cranially and entering the thorax through an intercostal defect. This case highlights the need for early and definitive surgical repair.

Midline Approach

Surgical access for ovariohysterectomy in bitches through the right lateral abdominal wall with an incision in its upper third in the direction from the anterior edge of the macula to the fourth nipple of the corresponding side of the breast is proposed. The article presents the results of studies obtained when used for the purpose of ovariohysterectomy in bitches of operative access through the right lateral and ventral abdominal wall. Research work was conducted on healthy mature bitches. The operations were performed in the area of the right lateral abdominal wall and in the umbilical region. On the lateral abdominal wall, an oblique-vertical incision was used at the border of the inguinal and iliac areas in the direction from the anterior edge of the macula to the fourth nipple of the corresponding side of the breast. The ventral abdominal wall was cut along the white line. It was found that when performing ovariohysterectomy in bitches using the proposed surgical access through the right lateral abdominal wall with a smaller wound size (P < 0.05), the duration of the operation and the healing period correspond to those when using median laparotomy. It is proved that operative access with oblique-vertical incision in the area of the right lateral abdominal wall at the border of the groin and anus during ovariohysterectomy in bitches provides favorable opportunities for surgical reception and closure of the surgical wound. The number of surgical sutures for sutures on the abdominal wall is less than in the case of ventral access (P < 0.01). It is also noted that in ovariohysterectomy in bitches, operative access through the right lateral abdominal wall with an incision in the direction from the anterior edge of the macula to the fourth nipple of the corresponding side of the breast may be recommended as an alternative access through the white line of the abdomen.

Abstract Aim Effects of component separation (CS) on abdominal wall musculature have only been investigated in smaller case series. The study aimed to compare abdominal wall alterations following endoscopic anterior component separation (EACS) or transverse abdominis release (TAR). Material and Methods Computed tomography scans were evaluated in patients who underwent open ventral hernia repair with TAR or EACS. Lateral abdominal wall muscle thickness and displacement were compared with preoperative images after bilateral CS and the undivided side postoperatively after unilateral CS. Results In total, 105 patients were included. The mean defect width was 12.2 cm. Fifty-five (52%) and 15 (14%) underwent bilateral and unilateral EACS, respectively. Five (5%) and 14 (13%) underwent bilateral and unilateral TAR, respectively. Sixteen (15%) underwent unilateral EACS and contralateral TAR. Complete fascial closure was achieved in 103 (98%) patients. The external oblique and transverse abdominis muscles were significantly laterally displaced with a mean of 2.74 cm (95% CI 2.29-3.19 cm) and 0.82 cm (0.07-1.57 cm) after EACS and TAR, respectively. The combined thickness of the lateral muscles was significantly decreased after EACS (mean decrease 10.5% [5.8-15.6%]) and insignificantly decreased after TAR (mean decrease 2.6% [-4.8-9.5%]), mean reduction difference EACS versus TAR 0.22 cm (-0.01-0.46 cm). One (1%) patient developed an iatrogenic linea semilunaris hernia after EACS. The recurrence rate was 19% after mean 1.7 years follow-up. Conclusions The divided muscle was significantly more laterally displaced after EACS compared with TAR. The thickness of the lateral muscles was slightly decreased after EACS and unchanged after TAR.

Abstract Aim Aim of the analysis was to evaluate whether preoperative botulinum toxin infiltration may facilitate anatomical midline reconstruction without the need for – otherwise pre-operative assumed – surgical component separation. Material and Methods Total of 58 patients with complex abdominal wall hernias were included in our single-center retrospective analysis between 03/2015 and 12/2020. Size of the defect, HSV/ACV-ratio, rectus-to-defect-width-ratio (“Carbonell-Index”) as well as risk factors were analyzed. In all patients muscles of the lateral abdominal wall were infiltrated with 300-500 IE of botulinum toxin 4 weeks prior to the abdominal wall reconstruction. CT scans were performed before and 4 weeks after the botulinum toxin infiltration. Results Total of 58 patients (M/F-ratio 36:22), with a mean age of 63.8 years were included in our analysis. Mean BMI was 29.5 kg/m². Total of 50 incisional, 3 umbilical, 2 posttraumatic diaphragmatic hernias and 3 scrotal hernias were analyzed. Surgical component separation after the infiltration with botulinum toxin was necessary in 43% of the cases. Conclusions Preoperative infiltration of the lateral abdominal wall musculature with botulinum toxin facilitated midline reconstruction of the abdominal wall without the need for myofascial release in 57%. Reduction of surgical trauma could therefore be achieved in several patients.
