Primary flap closure of perineal defects to avoid empty pelvis syndrome after pelvic exenteration in gynecologic malignancies: An old question to explore a new answer

Pelvic exenteration (PE) is a radical oncological surgical procedure proposed in patients with recurrent or persistent gynecological cancers. The radical alteration of pelvic anatomy and of pelvic floor integrity can cause major postoperative complications. Fortunately, PE can be combined with reconstructive procedures to decrease complications and functional and support problems of pelvic floor, reducing morbility and mortality and increasing quality of life. Many options for reconstructive surgery have been described, especially a wide spectrum of surgical flaps. Different selection criteria have been proposed to select patients for primary perineal defect flap closure without achieving any strict indication of the best option. The aim of this review is to focus on technical aspects and the advantages and disadvantages of each technique, providing an overview of those most frequently used for the treatment of pelvic floor defects after PE. Flaps based on the deep inferior epigastric artery, especially vertical rectus abdominis musculocutaneous (VRAM) flaps, and gracilis flaps, based on the gracilis muscle, are the most common reconstructive techniques used for pelvic floor and vaginal reconstruction. In our opinion, reconstructive surgery may be considered in case of total PE or type II/III PE and in patients submitted to prior pelvic irradiation. VRAM could be used to close extended defects at the time of PE, while gracilis flaps can be used in case of VRAM complications. Fortunately, numerous choices for reconstructive surgery have been devised. As these techniques continue to evolve, it is advisable to adopt an integrated, multi-disciplinary approach within a tertiary medical center.

Biosynthetic Mesh Reconstruction after Abdominoperineal Resection for Low Rectal Cancer: Cross Relation of Surgical Healing and Oncological Outcomes: A Multicentric Observational Study

BACKGROUND

Local wound complications are among the most relevant sequelae after an abdominoperineal resection (APR) for low rectal cancer. One of the proposed techniques to improve the postoperative recovery and to accelerate the initiation of adjuvant chemotherapy is the mesh reinforcement of the perineal wound. The aim of the current study is to compare the surgical and oncological outcomes after APR performed with a biosynthetic mesh reconstruction versus the conventional procedure.

METHODS

From 2015 to 2020, in two tertiary centres, the surgical outcomes, the wound events (i.e., surgical site infections, wound dehiscence and the complete healing time) and the oncological outcomes (i.e., time length to start adjuvant chemo-radiotherapy, an over 8-week delay in chemotherapy and the recurrence rate) were retrospectively analysed in patients undergoing APR reinforced with biosynthetic mesh (Group A) and conventional APR (Group B). Results Sixty-one patients were treated with APR (25 in Group A and 36 in Group B). Patients in Group A presented lower time for: healing (16 versus 24 days, p = 0.015), inferior perineal wound dehiscence rates (one versus nine cases, p = 0.033), an earlier adjuvant therapy start (26 versus 70 days, p = 0.003) and a lower recurrence rate (16.6% vs. 33.3%, p = 0.152).

CONCLUSIONS

In our series, the use of a biosynthetic mesh for the neo-perineum reconstruction after a Miles' procedure has resulted in safe, reproducible results affected by limited complications, guarantying a rapid start of the adjuvant therapy with clear benefits in oncological outcomes. Further randomized clinical trials with long-term follow-up are needed to validate these results.

Based on a review of the literature for each procedure, the article discusses procedural methods and techniques, indications for implementation, potential consequences and side effects of the procedure, nursing implications, patients' motives for undergoing the procedure, and positions of scientific institutions relative to the procedure.

Genital Reconstruction following Fournier's Gangrene

INTRODUCTION

Fournier's gangrene is a urological emergency, comprising of type I necrotizing fasciitis resulting in anatomic defects affecting the perineum, perianal region, and external genitalia in both men and women, often requiring reconstruction.

OBJECTIVES

The aim of this article is to provide a comprehensive review of the different reconstructive techniques for Fournier's gangrene.

METHODS

A literature search was performed on PubMed with the search terms "Fournier"s gangrene" "genital reconstruction" and "Fournier's gangrene phalloplasty." The European Association of Urology's guidelines on Urological infections were also consulted for recommendations.

RESULTS

Reconstructive procedures include primary closure, scrotal advancement flaps, fasciocutaneous flaps, myocutaneous flaps, skin grafts, and phalloplasty. There is insufficient evidence to support that flaps lead to better outcomes than skin grafts, or vice versa, particularly for scrotal defects. Both techniques have been shown to have satisfactory aesthetic results, with good skin color match and natural scrotal contour. With regards to phalloplasty, there is a lack of data specifically relating to Fournier's gangrene, as most articles were addressed toward gender affirmation surgery. Furthermore, there is a lack of guidelines in both the immediate and reconstructive management of Fournier's gangrene. Lastly, the outcomes reported following reconstructive surgery have been objective rather than subjective, meaning that patient satisfaction was rarely recorded.

CONCLUSION

Further research is required in the field of reconstructive surgery specific to Fournier's gangrene, which should also take into consideration patient demographics and subjective reports regarding cosmesis and sexual function.

The reconstructive strategy for pelvic oncological surgery with various types of MS-VRAM flaps

BACKGROUND

Muscle-sparing vertical rectus abdominis myocutaneous (MS-VRAM) flaps are widely used in pelvic reconstruction. Aiming at optimal reconstructive outcomes, flap design and modification should be individualized to restore various kinds of defects.

OBJECTIVE

Summarize an empirical strategy about MS-VRAM selection for different pelvic and perineal reconstructions.

METHODS

Thirty patients who underwent total pelvic exenteration and pelvic reconstruction surgery from 2009 to 2017 were enrolled. The patients were divided into four groups according to the type of MS-VRAM-based flap used in the procedure: the modified long vertical flap (n = 10), the wrapping flap (n = 6), the de-epithelialized flap (n = 6), and the cork flap (n = 8). The follow-up period was 1 year after the surgery. Flap size, drainage volume, postoperative satisfaction, and complications were recorded, and postoperative photographs were collected.

RESULTS

All of the patients achieved satisfying effect under the targeted reconstruction strategy. Of the four groups, the accurate cork flap finally acquires higher satisfaction, the shortest hospital stay, and the least total drainage volume. Meanwhile, the incidence of complications was not increased compared with the other groups.

CONCLUSIONS

A new reconstructive strategy for pelvic reconstruction was established. Functional or non-functional reconstruction was accomplished by using various MS-VRAM flaps. Among them, the cork flap is the most economical flap to reconstruct pelvic floor defects with minimal tissue requirement and donor trauma.

Aesthetic Outcomes of Perineal Reconstruction with the Lotus Petal Flap

The lotus petal flap can be applied for reconstruction of extensive defects in the vulvoperineal area. Studies on aesthetic outcomes are lacking. This study aimed to fill this gap.

Methods

All patients who underwent lotus petal flap reconstruction between October 2011 and December 2015 were asked permission to have their photographs used. Two questionnaires were used: (1) the Strasser score to assess the overall aesthetic results (range 0-15) and (2) the Patient and Observer Scar Assessment Scale (POSAS; range 6-60). Six plastic surgeons and 6 laymen filled in the Strasser score and the Observer scale of the POSAS. Patients filled in the Strasser score, the Patient scale of the POSAS and scored their overall satisfaction with the aesthetic results on a Likert scale (0-10).

Results

The photographs of 11 patients were included. The median Strasser score of all observers of 11.9 (range 0.0-75.0) indicated a mediocre aesthetic result. The median total POSAS score of 15.6 (range 6.0-41.0) indicated an aesthetically acceptable scar. Strasser and POSAS scores of the plastic surgeons and laymen did not differ significantly from the patients' scores. The patient satisfaction score with the aesthetic result was a median of 6.0 of 10.

Conclusions

The findings indicate that, overall, patients were moderately satisfied with the aesthetic results of their lotus petal flap reconstructions, as were the plastic surgeons and laymen. For clinical practice, it is important that the plastic surgeon manages expectations carefully before surgery, as it is possible that patients might experience a rather low aesthetic outcome after perineal reconstruction.

Flap Reconstruction of Perineal Defects after Pelvic Exenteration: A Systematic Description of Four Choices of Surgical Reconstruction Methods

BACKGROUND

The treatment of locally advanced or recurrent anorectal cancer requires radical surgery such as extralevator abdominoperineal resection and pelvic exenteration. Larger defects require flap reconstruction. The authors evaluated outcomes of different perineal reconstruction techniques.

METHODS

A systematic search was performed in the PubMed, Embase, and Cochrane databases. Studies reporting outcomes on perineal flap reconstruction in patients with anal or colorectal cancer were included. Data on patient characteristics, surgical details, perineal and donor-site complications, revision surgery, mortality, and quality of life were extracted. Articles were assessed using the Group Reading Assessment and Diagnostic Evaluation approach.

RESULTS

The authors included 58 mainly observational studies comprising 1988 patients. Seventy-three percent of patients had rectal cancer. The majority of 910 abdominoperineal resection patients underwent reconstruction with rectus abdominis flaps (91 percent). Dehiscence (15 to 32 percent) and wound infection (8 to 16 percent) were the most common complications. Partial flap necrosis occurred in 2 to 4 percent and flap loss occurred in 0 to 2 percent. Perineal herniation was seen in 6 percent after gluteal flap reconstruction and in 0 to 1 percent after other types of reconstruction. Donor-site complications were substantial but were reported inconsistently.

CONCLUSIONS

Clinical outcome data on perineal reconstruction after exenterative surgery are mostly of very low quality. Perineal reconstruction after pelvic exenteration is complex and requires a patient-tailored approach. Primary defect size, reconstruction aims, donor-site availability, and long-term morbidity should be taken into account. This review describes the clinical outcomes of four flap reconstruction techniques. Shared clinical decision-making on perineal reconstruction should be based on these present comprehensive data.

Optimal postoperative management of perineal flaps in oncologic patients undergoing extralevator abdominoperineal excision: An introduction of a postoperative monitoring and flap management protocol

There is extensive discussion regarding method of perineal defect closure extralevator abdominoperineal excision, but little consideration of optimal postoperative management of the flaps, or use of Enhanced Recovery After Surgery in flap reconstruction. Literature review revealed little discussion of optimum postoperative care of perineal flaps following extralevator abdominoperineal excision. We have developed a protocol for postoperative care of perineal flaps for use in conjunction with colorectal Enhanced Recovery After Surgery pathways, easily followed in units not specialising in plastic surgery. The protocol was developed using translatable evidence from guidelines for flap care from other subspecialties, as well as the experience of management of post-extralevator abdominoperineal excision perineal flaps in our trust, with the aim of enabling early detection of deterioration in this complex cohort, with a multidisciplinary enhanced recovery approach.

Flap coverage for necrotising soft tissue infections: A systematic review

BACKGROUND

Necrotising soft tissue infections (NSTI) are destructive and often life-threatening infections of the skin and soft tissue, necessitating prompt recognition and aggressive medical and surgical treatment. After debridement, the aim of surgical closure and reconstruction is to minimize disability and optimize appearance. Although skin grafting may fulfil this role, techniques higher on the reconstructive ladder, including local, regional and free flaps, are sometimes undertaken. This systematic review sought to determine the circumstances when this is true, which flaps were most commonly employed, and for which anatomical areas.

METHODS

A systematic review of the literature was conducted utilising electronic databases (Medline, Embase, Cochrane Library). Full text studies of flaps used for the management of NSTI's (including Necrotising Fasciitis and Fournier Gangrene) were included. The web-based program 'Covidence' facilitated storage of references and data management. Data obtained in the search included reference details (journal, date and title), the study design, the purpose of the study, the study findings, number of patients with NSTI included, the anatomical areas of NSTI involved, the types of flaps used, and the complication rate.

RESULTS

After screening 4555 references, 501 full text manuscripts were assessed for eligibility after duplicates and irrelevant studies were excluded. 230 full text manuscripts discussed the use of 888 flap closures in the context of NSTI in 733 patients; the majority of these were case series published in the last 20 years in a large variety of journals. Reconstruction of the perineum following Fournier's gangrene accounted for the majority of the reported flaps (58.6%). Free flaps were used infrequently (8%), whereas loco-regional muscle flaps (18%) and loco-regional fasciocutaneous flaps (71%) were employed more often. The reported rate of partial or complete flap loss was 3.3%.

CONCLUSION

Complex skin and soft tissue defects from NSTIs, not amenable to skin grafting, can be more effectively and durably covered using a spectrum of flaps. This systematic review highlights the important contribution that the plastic surgeon makes as an integral member of multidisciplinary teams managing these patients.

Ten-Year experience with vertical rectus abdominis myocutaneous flap for reconstruction of abdominoperineal resection defects

Purpose

We evaluate outcomes of our single center using vertical rectus abdominis myocutaneous (VRAM) flaps for reconstruction after abdominoperineal resection (APR). Our goal was to analyze factors that may affect perineal wound healing, a problematic complication with APR reconstructions due to location and high frequency of neoadjuvant chemoradiation.

Methods

This single-center, retrospective study analyzed all VRAM flap perineal reconstruction patients after APR defect over a 10-year period (from July 2008 to June 2018). Outcome measures focused on factors that may affect perineal wound healing complication rates: cancer stage (I/II vs III/IV), neoadjuvant chemoradiation, surgeon's years in practice (<5 years vs >5 years), and pelvic closed suction drain use.

Results

Twenty-eight patients met inclusion criteria. The overall major perineal wound complication rate was 14.3% (4 patients). Lack of perioperative closed suction pelvic drain use was associated with a significantly higher rate of major perineal wound complications (28.6% vs 0% and p = 0.031). All four major wound complications occurred in patients who did not have a pelvic drain. The major perineal wound complication rate for patients who underwent neoadjuvant chemoradiation was 22% vs 0% with no neoadjuvant chemoradiation (p = 0.107).

Conclusion

While our cohort represents a relatively small single-center study, our 14.3% rate of major perineal wound complications is consistent with previous studies in the literature. Our findings show that perioperative pelvic closed suction drain use is associated with a lower rate of perineal wound complications. While neoadjuvant chemoradiation trended toward a higher incidence of perineal wound complications, it did not reach statistical significance.

Quality of Life, Sexual Functioning, and Physical Functioning Following Perineal Reconstruction with the Lotus Petal Flap

BACKGROUND

Lotus petal flaps (LPF) may be used for the reconstruction of extralevator abdominoperineal defects that cannot be closed primarily. Limited data are available on how perineal reconstruction with the LPF impacts on patients' quality of life (QoL), sexual functioning, and physical functioning.

METHODS

A cross-sectional study was performed following perineal reconstruction with the LPF. The QoL of patients having undergone LPF reconstruction was compared with a control group in which perineal defects were closed without flaps. Sexual and physical functioning (presence of perineal herniation and range of motion [ROM] of the hip joints) could only be evaluated in the LPF group. Psychometrically sound questionnaires were used. Physical functioning was evaluated subjectively with binary questions and objectively by physical examination.

RESULTS

Of the 23 patients asked to participate, 15 (65%) completed the questionnaires and 11 (47%) underwent physical examination. In the control group, 16 patients were included. There were no significant differences in QoL between the LPF and control groups. Within the LPF group, 33% of patients were sexually active postoperatively compared with 87% preoperatively. No perineal herniation was found. The ROM of the hip joints was bilaterally smaller compared with the generally accepted values.

CONCLUSIONS

Conclusions should be made with care given the small sample size. Despite a supposedly larger resection area in the LPF group, QoL was comparable in both groups. Nonetheless, reconstruction seemed to affect sexual function and physical function, not hampering overall satisfaction.

Biological mesh used to repair perineal hernias following abdominoperineal resection for anorectal cancer

PURPOSE

This study aimed to determine the outcome for patients who had undergone perineal hernia repair, via a perineal approach, using a biological mesh post-abdominoperineal excision (APE) for anorectal cancer.

METHOD

All consecutive patients having undergone perineal hernia repair involving an extracellular matrix of porcine small intestinal submucosa at our hospital between 2015 and 2018 were included. Follow-up clinical examinations and computed tomography scans were performed.

RESULTS

Six patients were treated surgically for symptomatic perineal hernia after a median of 31 months from APE. The median follow-up after hernia repair was 11 months (interquartile range [IQR], 6-35 months). Three patients (50%) developed a recurrent perineal hernia after a median interval of 6 months.

CONCLUSION

Perineal hernia repair using a biological mesh resulted in a high recurrence rate in patients who had undergone APE for anorectal cancer.

Reconstruction of Perineal Defects: A Comparison of the Myocutaneous Gracilis and the Gluteal Fold Flap in Interdisciplinary Anorectal Tumor Resection

Introduction: Resection of anorectal malignancies may result in extensive perineal/pelvic defects that require an interdisciplinary surgical approach involving reconstructive surgery. The myocutaneous gracilis flap (MGF) and the gluteal fold flap (GFF) are common options for defect coverage in this area. Here we report our experience with the MGF/GFF and compare the outcome regarding clinical key parameters.

Methods: In a retrospective chart review, we collected data from the Department of Plastic Surgery of the University of Freiburg from December 2008–18 focusing on epidemiological, oncological, and therapy-related data including comorbidities (ASA Classification) and peri-/postoperative complications (Clavien-Dindo-System).

Results: Twenty-nine patients were included with a mean follow-up of 17 months. Of the cases, 19 (65.5%) presented with recurrent disease, 21 (72.4%) received radiochemotherapy preoperatively, 2 (6.9%) received chemotherapy alone. Microscopic tumor free margins were achieved in 25 cases (86.2%). 17 patients (7 men, 10 women, rectal adenocarcinoma n = 11; anal squamous cell carcinoma n = 6; mean age 58.5 ± 10.68, mean BMI 23.1, mean ASA score 2.8) received a MGF (unilateral n = 10; bilateral n = 7). Twelve patients (7 men, 5 women, rectal adenocarcinoma n = 7; anal squamous cell carcinoma n = 4, proctodeal gland carcinoma n = 1, mean age 66.2 ± 9.2, mean BMI 23.6, mean ASA score 2.6) received coverage with a GFF (unilateral n = 4; bilateral n = 8). Mean operation time of coverage was 105 ± 9 min for unilateral and 163 ± 11 for bilateral MGFs, 70 ± 13 min for unilateral and 107 ± 14 for bilateral GFFs. Complications affected 62%. There was no significant difference in the complication rate between the MGF- and GFF-group. Complications were mainly wound healing disorders that did not extend the hospital stay. No flap loss and no complication that lead to long-lasting disability was documented (both groups). Pain-free sitting took more time in the GFF-group due to the location of the donor site.

Conclusion: MG-flaps and GF-flaps prove to be reliable and robust techniques for perineal/pelvic reconstruction. Though flap elevation is significantly faster for GF-flaps, preoperative planning and intraoperative Doppler confirmation are advisable. With comparable complication rates, we suggest a decision-making based on distribution of adipose tissue for dead space obliteration, intraoperative patient positioning, and perforator vessel quality/distribution.

Reconstruction of critically-sized perineal defect with perforator flap puzzle technique: a case report

Extensive defects in perineal reconstruction cannot be effectively reconstructed with only a single perforator flap or other conventional techniques. We present a combination of three different types of flaps including pedicled ALT-rectus-vastus lateralis, gracilis-PAP flap and two IGAP flaps as an alternative option for reconstructing a critically-sized perineal defect.

Transvaginal Small Bowel Evisceration following Abdominoperineal Resection

Abdominoperineal resection (APR) is one of the surgical techniques performed for the distal rectal cancer. The perineal herniation is one of the complications of APR surgery. In this report, we aim to demonstrate a rare case of small bowel evisceration and strangulation secondary to the transvaginal herniation evolved in the late stage after perineal hernia repair following laparoscopic APR.

Reconstruction of Large Defects in the Perineal Area Using Multiple Perforator Flaps

Background

Perineal defects are commonly encountered during the treatment of conditions such as malignancy, infectious disease, and trauma. Covering large defects in the perineal area is challenging due to its complicated anatomy and the need for functional preservation.

Methods

Fourteen patients who underwent reconstructive surgery with multiple perforator flaps for defects >100 cm² in the perineal area were included in this retrospective cohort study. Characteristics of the perforator flap operation and postoperative outcomes were reviewed.

Results

Reconstruction was performed using 2 perforator flaps for 13 patients and 3 perforator flaps for 1 patient. Internal pudendal artery perforator flaps were mainly used for covering the defects. The average defect size was 176.3±61.8 cm² and the average size of each flap was 95.7±31.9 cm². Six patients had minor complications, such as wound dehiscence and partial necrosis of the flap margin, which were corrected with simple revision procedures.

Conclusions

Multiple perforator flaps can be used to achieve successful reconstructions of large perineal defects that are difficult to reconstruct with other coverage methods.
