Laparoscopic mesh repair of transverse rectus abdominus muscle and deep inferior epigastric flap harvest site hernias

Robotic Repair: An Alternative Technique for Rectus Diastasis and Abdominal Bulge Following DIEP Flap Breast Reconstruction

BACKGROUND

The deep inferior epigastric artery perforator (DIEP) flap is the gold standard in autologous breast reconstruction. Despite advances in perforator dissection, abdominal morbidity still occurs. Traditional rectus diastasis (RD), abdominal bulge, and hernia repair with open techniques are associated with higher complication rates and recurrence.

OBJECTIVES

We present a novel case series of robotic repair of symptomatic RD and/or abdominal bulge with concurrent hernia following DIEP flap surgery.

METHODS

A single-center, retrospective review was conducted of 10 patients who underwent bilateral DIEP flap breast reconstruction and subsequent robotic repair of RD and/or abdominal bulge and hernia. Preoperative demographics and postoperative clinical outcomes were reviewed. RD up to 5 cm, abdominal bulge, and any concurrent ventral/umbilical hernias were repaired robotically with retrorectus plication and macroporous mesh reinforcement.

RESULTS

The average age and BMI were 49 years (range 41-63) and 31 kg/m2 (range 26-44), respectively. The average number of perforators harvested per flap was 2.5 (range 1-4). Average RD and hernia size were 3.95 cm (range 2-5) and 5.8 cm2 (1-15), respectively. Eight patients stayed 1 night in the hospital, and 2 went home the same day as the robotic repair. No patients were converted to open technique and none experienced complications within 30 days.

CONCLUSIONS

For patients who experience donor site morbidity following DIEP flap breast reconstruction, minimally invasive robotic repair of RD and/or abdominal bulge with hernia can be performed with mesh reinforcement. This technique is effective, with low complication rates, and should be considered over open repair.

Outcomes of posterior component separation with transversus abdominis release for repair of abdominally based breast reconstruction donor site hernias

PURPOSE

Abdominally based autologous breast reconstruction (ABABR) is common after mastectomy, but carries a risk of complex abdominal wall hernias. We report experience with posterior component separation (PCS) and transversus abdominis release (TAR) with permanent synthetic mesh repair of ABABR-related hernias.

METHODS

Patients at Cleveland Clinic Foundation and Penn State Health were identified retrospectively. Outcomes included postoperative complications, hernia recurrence, and patient-reported outcomes (PROs): Hernia Recurrence Inventory, HerQLes Summary Score, Patient-Reported Outcome Measurement Information System (PROMIS) Pain Intensity 3a Survey, and the Decision Regret Scale (DRS).

RESULTS

Forty patients underwent PCS/TAR repair of hernias resulting from pedicled (35%), free (5%), muscle-sparing TRAMs (15%), and DIEPs (28%) from August 2014 to March 2021. Following PCS, 30-day complications included superficial surgical site infection (13%), seroma (8%), and superficial wound breakdown (5%). Five patients (20%) developed clinical hernia recurrence. At a minimum of 1 year, 17 (63%) reported a bulge, 12 (44%) reported pain, median HerQLes Quality Of Life Scores improved from 33 to 63/100 (p value < 0.01), PROMIS 3a Pain Intensity Scores improved from 52 to 38 (p value < 0.05), and DRS scores were consistent with low regret (20/100).

CONCLUSION

ABABR-related hernias are complex and technically challenging due to missing abdominal wall components and denervation injury. After repair with PCS/TAR, patients had high rates of recurrence and bulge, but reported improved quality of life and pain and low regret. Surgeons should set realistic expectations regarding postoperative bulge and risk of hernia recurrence.

Infection of PTFE mesh 15 years following pedicled TRAM flap breast reconstruction: mechanism and aetiology

The pedicled transverse rectus abdominis myocutaneous (TRAM) flap procedure is still widely used for breast reconstruction. The repair of the flap harvest site in the transverse rectus abdominis muscle and sheath is often assisted by the use of prosthetic meshes. This decreases the risk of abdominal wall weakness and herniation but, being a foreign body, it also carries the risk of infection. In this report, we describe the case of a 63-year-old patient who, whilst receiving chemotherapy for metastatic breast cancer, presented with an infected polytetrafluoroethylene mesh 15 years after pedicled TRAM flap immediate breast reconstruction. This necessitated mesh removal to treat the infection. Following a thorough review of the English literature, this is the longest recorded presentation of an abdominal prosthetic mesh infection. The mechanism and aetiology of such a late complication are discussed.

The management of abdominal contour defects following TRAM flap breast reconstruction

BACKGROUND

Incisional hernia can develop following breast reconstruction with abdominal tissue regardless of technique, and the management is often challenging.

OBJECTIVES

The authors characterize hernias following transverse rectus abdominis musculocutaneous (TRAM) flap procedures and evaluate outcomes of different strategies for repair.

METHODS

All patients who underwent repair of a TRAM-related hernia or bulge between 2003 and 2011 at a single institution were retrospectively reviewed. A minimum of 2 years' follow-up was required for inclusion in this series. Outcomes of different techniques for repair were compared and risk factors for hernia recurrence identified.

RESULTS

Forty-three patients underwent repair of a TRAM-related hernia or bulge, most often with mesh (74.4%, n=32). At a mean overall follow-up of 5.2 years, 9 patients (20.9%) developed recurrent hernia or bulge. Compared to primary suture closure, the use of mesh was protective against recurrence (odds ratio, 0.05; 95% confidence interval, 0.00-0.65; P=.02), with the best results observed with fascial closure and underlay mesh reinforcement.

CONCLUSIONS

Incisional hernia following TRAM flap breast reconstruction can be a challenging problem. Attention to surgical technique and the use of mesh minimize the risk of recurrence.

Is Muscular Atrophy a Contraindication in Laparoscopic Abdominal Wall Defect Repair? A Prospective Study

Laparoscopic surgery for abdominal wall hernias improves short-term results as compared with open hernia surgery. However, no evidence exists to recommend this approach for pseudohernias, which are abdominal wall defects postsurgery caused by denervation and muscular atrophy. The purpose of this study is to analyze whether the laparoscopic approach benefits patients with a pseudohernia. A prospective nonrandomized, single-center clinical study was conducted of 24 patients operated on for pseudohernia. This study was designed with the basic principle of one unit, one surgeon, one mesh, and two techniques (laparoscopic or open double prosthetic repair). The primary end point was assessment of the abdominal wall according to: 1) abdominal perimeter; 2) computed tomography scan; and 3) degree of satisfaction. The secondary end points were intraoperative parameters and comorbidity. Laparoscopy offered no benefits in patients with pseudohernias. Open surgery offered no significant differences in intra- and postoperative morbidity, but if the initial weakness improved with a decrease in abdominal perimeter and visceral content, then there was more than 90 per cent satisfaction ( P < 0.05). The laparoscopic approach does not improve the bulge caused by abdominal muscle atrophy. The option of a muscular and prosthetic reconstruction provides better clinical and cosmetic results.
