Reconstructing abdominal wall defects with a free composite tissue flap: A case report

BACKGROUND

Reconstructive repair of huge full-thickness abdominal wall defects following debridement for abdominal electric burns remains a clinically challenging task. An ideal abdominal wall repair means a re-closure of the defected abdominal wall with pedicled neurovascular myofascial flaps, restoration of the abdominal wall integrity, and maintenance of the abdominal wall muscle tension to prevent the occurrence of abdominal wall hernia. When treating huge full-thickness defects, composite autologous tissue flaps are a good option for the repair.

CASE SUMMARY

This study reported the case of a 43-year-old male patient suffering from full-thickness abdominal wall defects complicated with necrosis of multiple bowel segments and duodenal leak following high-voltage burns involving the left upper limb and abdomen. After debridement for abdominal electric burns and end-to-end anastomosis for the necrotic bowels, reconstruction with acellular dermal matrix grafting and vacuum sealing drainage were performed for temporary abdominal closure. The remaining 18 cm × 15 cm full-thickness abdominal wall defect was repaired using a combined anterolateral thigh and tensor fascia lata free flap. The proposed method achieved the functional reconstruction of the abdominal wall.

CONCLUSION

This approach restored the abdominal wall integrity, maintained certain muscle tension, avoided abdominal hernia, reached satisfactory aesthetic effect, and resulted in no complications in the grafting regions.

Autologous abdominal wall reconstruction using anterolateral thigh and iliotibial tract flap after extensive tumor resection: A case series study of 50 consecutive cases

BACKGROUND

The utility of anterolateral thigh (ALT) + iliotibial tract (ITT) flaps for the reconstruction of large abdominal wall defects has been reported, especially in cases with huge skin defects, surgical contamination, or a history of radiotherapy. However, previous reports have mainly described short-term results such as flap success rates or incidence of wound complications. The present study reviewed 50 consecutive cases of abdominal wall reconstruction using an ALT+ITT flap after extensive tumor resection and evaluated the durability of this approach (incidence of bulge or hernia) and the factors affecting the results.

PATIENTS AND METHODS

A detailed retrospective review of 50 consecutive cases was conducted. Computed tomography or magnetic resonance imaging findings were reviewed to assess the incidence of abdominal bulge or hernia. Items extracted as variables from patient records were subjected to univariate and multivariate logistic regression analyses to identify their relationship with postoperative abdominal bulge or hernia.

RESULTS

Forty-six cases that were followed up for more than six months were analyzed. Twenty-three patients (50.0%) developed abdominal bulge, while none (0%) developed hernia. The multivariate logistic regression analysis revealed that old age and a high body mass index were independently associated with abdominal bulge, while abdominal defect size was not.

CONCLUSIONS

Abdominal wall reconstruction using an ALT+ITT flap after extensive tumor resection was considered a reasonable option with a low risk of hernia despite a marked incidence of postoperative abdominal bulge; however, the usage of additional material may be considered depending on the situation.
