Radiological incidence of donor-site incisional hernia and parastomal hernia after vertical rectus abdominus myocutaneous flap-based reconstruction following colorectal surgery

Aim

A vertical rectus abdominis myocutaneous (VRAM) flap is commonly used to reconstruct perineal defects for low rectal and anal cancer. The incidence of midline incisional hernias after VRAM reconstruction varies from 3.6% when detected clinically to 50% when detected radiologically. The aim of this study is to accurately determine the radiological incidence of donor-site incisional and parastomal hernia following VRAM reconstruction.

Method

This was a retrospective cohort study of patients undergoing colorectal surgery requiring VRAM reconstruction over 10 years. Data were collected on patient demographics, indication for surgery and surgical procedure, including details of any hernia repair. Images from surveillance CTs were reviewed for the presence and size of midline incisional and/or parastomal hernias. Parastomal hernias were classified based on the European Hernia Society (EHS) classification.

Results

One hundred and seventy three patients were included in the analysis. The median age was 67 years (range 29–88 years) and the median length of follow-up was 49 months (interquartile range 24.3–71.0 months). The cumulative incidence of donor-site incisional hernia after VRAM at 1, 2 and 5 years was 15.1%, 25.4% and 29.1%, respectively. The cumulative incidence for PSH at 1, 2 and 5 years was 33.1%, 46.6% and 53.3%, respectively (95% CI 45.4%–60.5%).

Conclusion

Most patients who develop donor-site incisional hernia and parastomal herniation following VRAM tend to do so within the first 2 years. Although the use of CT imaging improves the diagnosis of donor-site incisional and parastomal hernias, the clinical significance of this is unknown.     

Outcomes of immediate vertical rectus abdominis myocutaneous flap reconstruction for irradiated abdominoperineal resection defects

BACKGROUND: Perineal wound complications after chemoradiotherapy and abdominoperineal resection (APR) for anorectal cancer occur in up to 60% of patients, including perineal abscess and wound dehiscence. Vertical rectus abdominis myocutaneous (VRAM) flaps have been used in an attempt to reduce these complications by obliterating the noncollapsible dead space with vascularized tissue and closing the perineal skin defect with nonirradiated flap skin. Many surgeons are reluctant to use VRAM flaps unless primary closure is not possible. STUDY DESIGN: All patients who underwent chemoradiotherapy and APR during a 12-year period at the University of Texas MD Anderson Cancer Center were retrospectively reviewed. Patient, tumor, and treatment characteristics and surgical complications and outcomes were compared between patients who underwent VRAM flap reconstruction of wounds that could have been closed primarily (flap group, n = 35) and those who had primary closure of the perineal wound (control group, n = 76). RESULTS: Overall, there were no significant differences in the incidence of perineal wound complications between the groups; the flap group had a significantly lower incidence of perineal abscess (9% versus 37%, p = 0.002), major perineal wound dehiscence (9% versus 30%, p = 0.014), and drainage procedures required for perineal/pelvic fluid collections (3% versus 25%, p = 0.003) than the control group had. Despite flap harvest and the need for donor site closure in the flap group, there was no significant difference in abdominal wall complications between groups during the study's mean patient followup of 3.8 years. CONCLUSIONS: VRAM flap reconstruction of irradiated APR defects reduces major perineal wound complications without increasing early abdominal wall complications. Strong consideration should be given to immediate VRAM flap reconstruction after chemoradiation and APR.     

Bilateral pedicled myocutaneous vertical rectus abdominus muscle flaps to close vesicovaginal and pouch-vaginal fistulas with simultaneous vaginal and perineal reconstruction in irradiated pelvic wounds

Chronic postoperative pouch-vaginal and vesicovaginal fistulas after hysterectomy and irradiation to treat advanced cervical cancer do not respond to conventional treatment because of the low vascularity in the irradiated area. We present the successful repair of these complications in a female patient, in whom several vaginal and abdominal approaches had been tried and had resulted not only in failure but also in tissue loss and fibrosis and persisting fistulas. First, a synchronous vaginoabdominal approach using a vertical myocutaneous distally based rectus abdominis myocutaneous flap was used successfully to close a pouch-vaginal fistula and simultaneously reconstruct the posterior vaginal wall. In a second approach, the persisting vesicovaginal fistula was closed by a right rectus abdominis myocutaneous flap while simultaneously reconstructing the anterior vaginal wall, closing the enterocutaneous stoma and performing an appendicovesicostomy as a continence channel for catheterization. Despite unfavorable local wound situations, including an enterocutaneous stoma through the rectus abdominis and various previous incision lines, the transfer of axially well-vascularized tissue can solve these problem wounds. Consecutive bilateral use of the rectus abdominis flap may be necessary to deal with extensive pelvic wounds. This technique should be considered as one repair modality in irradiated pelvic wounds with fistulas. Previous enterostomy is not a contraindication to the use of this flap.     

Reconstruction with rectus abdominis myocutaneous flap for total glossectomy with laryngectomy

From October 1999 to July 2005, defects after total glossectomy with laryngectomy (TGL) for cancer of the tongue or middle pharynx were reconstructed with rectus abdominis myocutaneous (RAMC) flaps in nine patients. The skin flaps were designed larger in width than the original defect to create a funnel-shaped oropharynx and prevent stricture. Six patients had uneventful postoperative courses and began to eat perorally 8 to 15 days postoperatively. One patient suffered flap necrosis due to arterial thrombosis and two patients had leakage. Eventually, eight patients could eat soft foods or gruel, except one patient who had ingested food through a gastrostomy preoperatively. When TGL was performed without mandibulectomy, the blood supply for the remnant mucosa of the backside of the mandible is generally not good, for which the reconstruction with the overlapping deepithelialized flap and muscle is useful for prevention of the fistula formation. We considered that the RAMC flap is a good option for reconstruction after TGL.     

An investigation of the application of laser-assisted indocyanine green fluorescent dye angiography in pedicle transverse rectus abdominus myocutaneous breast reconstruction

BACKGROUND:

Pedicle transverse rectus abdominus myocutaneous (pTRAM) flaps remain the most common method of autologous tissue breast reconstruction. Using pTRAM flaps, complications often arise postoperatively, secondary to inadequate circulation. Tissues from distant angiosomes are associated with poorer perfusion, but this differs among patients. Many modalities have been used to reduce the risk of complications, but none have achieved widespread application. The authors believe that laser-assisted indocyanine green fluorescent dye angiography (LA-ICGA) can potentially reduce the risk of complications.

METHODS:

In two routine, single-pedicle, ipsilateral pTRAM flaps, LA-ICGA imaging was performed following the division of the distal rectus muscle and deep inferior epigastric pedicle. The resulting images were used to guide design of the flap and debridement.

RESULTS:

In case 1, good perfusion was observed in zone 1 and part of zone 2. In case 2, good perfusion was observed in zone 1 and 50% of zone 3, with little perfusion in zone 2. In both cases, tissues with poor perfusion were debrided before transfer and inset. In both patients, there were no issues with wound healing, tissue necrosis or fat necrosis.

CONCLUSIONS:

The variability of perfusion of the pTRAM flap among individuals is well appreciated. LA-ICGA helped to determine the limits of good perfusion and, therefore, the limits of tissue to be preserved for transfer and inset. This helped to avoid harvesting poorly perfused tissue that would have almost certainly experienced necrosis and, ultimately, would have reduced the risk of postoperative complications.     

Transecting the rectus abdominus muscle

The gastrointestinal stapler was pioneered in 1920 by Aladar Petz. It was originally designed to simplify bowel anastomosis and to reduce peritoneal contamination. The gastrointestinal stapler can be used to transect the rectus abdominus effectively. We describe the technique for harvesting the transverse rectus abdominus muscle flap.     

Ventricular standstill: a complication of intrapleural anesthesia using bupivacaine in a patient with free transverse rectus abdominus myocutaneous flap breast reconstruction

Transverse rectus abdominus myocutaneous (TRAM) flap is one of the commonly used techniques for breast reconstruction. Postoperative pain relief is of paramount importance following TRAM flap breast reconstruction to avoid potentially preventable complications like chest infection. Several methods of pain control are available, including intrapleural anesthesia. Here we report a case of a patient who developed ventricular standstill as a complication of intrapleural bupivacaine.     

Vaginal reconstruction using a vertical rectus abdominis myocutaneous flap in a child: a case report.

Rhabdomyosarcoma is the most common soft tissue sarcoma in infants and children younger than 15 years old. Multimodal treatment using chemotherapy, radiation, and surgery have increased survival. Because of the potential for long-term survival, the importance of organ preservation and vaginal and pelvic reconstruction has been recognized. The authors report a case in which special circumstances led to vaginal reconstruction concomitantly with exenteration surgery. The authors present the first reported use of a vertical rectus abdominis myocutaneous flap in a child and describe the technique and its potential advantages.     

Reconstruction of extensive partial or total sacrectomy defects with a transabdominal vertical rectus abdominis myocutaneous flap

Following partial or total sacrectomy, extensive soft tissue defects are frequently created. These ablations typically involve an anterior and a posterior approach, creating a large communication between the abdominal cavity and the central gluteal region. Local flap options are usually not sufficient for definitive closure of these large defects. We have found that the most useful option for reconstruction in these cases is a vertical rectus abdominis myocutaneous (VRAM) flap, passed transabdominally through the peritoneal cavity into the sacral defect during the initial anterior-approach portion of the procedure and then inset following completion of the posterior-approach final resection. Advantages of the VRAM flap are that it can supply ample skin, as well as soft tissue bulk, is easy to perform, and does not require microvascular techniques. Utilizing a prospectively maintained database, all patients over the last 14 years who underwent reconstruction utilizing a transabdominal VRAM flap following extensive partial or total sacrectomy with intraabdominal communication were identified. A retrospective chart review was then performed. Our study population consisted of 12 patients with a mean age of 58.5 years. Following sacrectomy, all patients underwent reconstruction with a VRAM flap. Flap sizes averaged 9.1 x 27 cm. Early flap complications included 3 small areas of flap necrosis at the distal, superior portion of the flap, 2 of which required minimal operative intervention of debridement and reclosure. No late flap complications have occurred, and all 12 patients completely healed, with a mean follow-up time of 29.1 months. Following sacrectomy, extensive soft tissue defects are created in the sacral area and communicate with the abdominal cavity. In these situations, we have found the inferiorly-based pedicled VRAM, passed transabdominally, to be the most reliable and useful choice of flap reconstruction. It has a low incidence of complications, low morbidity, and is easy to perform with a high success rate.     

Use of the vertical rectus abdominis myocutaneous flap after abdominoplasty.

A vertical rectus abdominis myocutaneous flap was used to provide cover for a recurrent angiosarcoma in the abdominal skin. Of note, the patient had 9 years previously undergone formal abdominoplasty to allow closure following excision of the primary tumour. This flap is normally reliant on myocutaneous perforators originating from the deep epigastric system, which are divided during abdominoplasty. Despite this, the flap survived well, implying that a new blood supply had formed during the intervening years. This flap can, therefore, be considered a possible option in reconstructive cases where other options are limited, despite a preceding abdominoplasty. In the future because of the increasingly common occurrence of abdominoplasty in young females, this procedure may need to be considered.     

Simultaneous bilateral breast reconstruction with the transverse rectus abdominus musculocutaneous free flap.

OBJECTIVE: The purpose of the study was to assess the results and morbidity associated with simultaneous bilateral TRAM free flap breast reconstruction and describe refinements in its surgical technique. SUMMARY BACKGROUND DATA: Bilateral prophylactic total mastectomies might be an agreeable option for those patients at highest risk for breast cancer if autogenous tissue breast reconstruction could be performed with reasonable technical ease and acceptable morbidity. However, some surgeons harbor reservations regarding the extensiveness of the surgery, the associated morbidity, and the aesthetic quality of the resulting outcome. METHODS: A multicenter retrospective review of clinical experience with 120 consecutive patients who underwent 240 simultaneous bilateral TRAM free flap breast reconstructions was developed. RESULTS: The average operating time, including the time required for the breast ablative portion of the procedures, was 8.6 hours. The average length of hospitalization was 7.6 days. However, for the last 40 patients, these figures were reduced to 7.1 hours and 6.1 days, respectively. Nonautologous blood transfusions were needed in 33 cases (28%), but only 1 was required in the last 40 patients. Thromboses developed in six of 240 flaps (2.5%): 4 were arterial and 2 were venous. Re-exploration allowed us to restore circulation in five flaps, whereas one flap was unsalvageable and was replaced successfully with an alternate flap. An uncomplicated deep vein thromboses developed in one patient with a history of recurrent deep vein thromboses that had no adverse effect on her outcome. Minor complications developed in 18 patients (15%) (e.g., hematoma, partial wound necrosis, wound infection, or prolonged postoperative ileus) that did not affect the long-term outcome. Fourteen patients (11.6%) had abdominal wall weakness or hernias. Follow-up time averaged 37.2 months (range, 14-62 months). On last follow-up, patients' self-reported overall satisfaction with the procedure was 56% excellent, 40% good, and 4% fair.CONCLUSIONS: Simultaneous bilateral free flap reconstruction is technically feasible with a high rate of success and an acceptable morbidity. When performed by experienced surgeons, bilateral prophylactic total mastectomies combined with simultaneous bilateral TRAM free flap reconstruction may provide an adequate surgical option with aesthetically acceptable results for patients at high risk for breast cancer.
