Closing the gap: evidence-based surgical treatment of rectus diastasis associated with abdominal wall hernias

Correction of Rectus Abdominis Diastasis: A Prospective Comparative Study Between a New Suturable Polypropylene Mesh vs Polypropylene Standard Suture Plication

BACKGROUND

Duramesh (Mesh Suture Inc., Chicago, IL) is a new suturing concept, combining the principles of mesh with the precision, flexibility, and versatility of a suture, suitable also for abdominal rectus diastasis (ARD) correction.

OBJECTIVES

This prospective research aimed to compare mesh with the standard polypropylene suture plication for rectus diastasis repair with regard to safety (infection, seroma, hematoma, surgical wound dehiscence, and fistula rates and hospital stay); effectiveness (ARD recurrence by ultrasound sonography, palpability of the muscular suture, surgical time, and postoperative pain evaluation); and satisfaction of the patients based on the BODY-Q, a patient-reported outcome measure.

METHODS

Sixty-five of the initial 70 patients who underwent rectus diastasis repair with a 6-month follow-up were randomly divided into 2 groups, comprising 33 patients treated with Duramesh and 32 patients treated with standard 0 polypropylene suture plication. Data regarding infection, seroma, hematoma, surgical wound dehiscence, and fistula rates; hospital stay; ARD recurrence; palpability of the muscular suture; surgical time; postoperative pain evaluation (measured by visual analog scale, or VAS); and the BODY-Q were analyzed by Prism 9 (GraphPad Software Inc., San Diego, CA).

RESULTS

No significant differences were reported between the 2 groups with regard to infection, seroma, hematoma, surgical wound dehiscence, and fistula rates and hospital stay. The mesh decreased the time required to perform plication compared with standard polypropylene detached sutures. No statistically significant differences were found with respect to the VAS and BODY-Q data.

CONCLUSIONS

Duramesh 0 application for rectus diastasis repair is safe and effective without compromising aesthetic improvement when compared with standard 0 polypropylene plication.

Linea alba 3D morphometric variability by CT scan exploration

PURPOSE

The width of the Linea alba, which is often gauged by inter-rectus distance, is a key risk factor for incisional hernia and recurrence. Previous studies provided limited descriptions with no consideration for width, location variability, or curvature. We aimed to offer a comprehensive 3D anatomical analysis of the Linea alba, emphasizing its variations across diverse demographics.

METHODS

Using open source software, 2D sagittal plane and 3D reconstructions were performed on 117 patients' CT scans. Linea alba length, curvature assessed by the sagitta (the longest perpendicular segment between xipho-pubic line and the Linea alba), and continuous width along the height were measured.

RESULTS

The Linea alba had a rhombus shape, with a maximum width at the umbilicus of 4.4 ± 1.9 cm and a larger width above the umbilicus than below. Its length was 37.5 ± 3.6 cm, which increased with body mass index (BMI) (p < 0.001), and was shorter in women (p < 0.001). The sagitta was 2.6 ± 2.2 cm, three times higher in the obese group (p < 0.001), majorated with age (p = 0.009), but was independent of gender (p = 0.212). Linea alba width increased with both age and BMI (p < 0.001-p = 0.002), being notably wider in women halfway between the umbilicus and pubis (p = 0.007).

CONCLUSION

This study provides an exhaustive 3D description of Linea alba's anatomical variability, presenting new considerations for curvature. This method provides a patient-specific anatomy description of the Linea alba. Further studies are needed to determine whether 3D reconstruction correlates with pathologies, such as hernias and diastasis recti.

Laparoscopic Ventral Hernia Repair

The laparoscopic approach to ventral hernia repair is a safe and effective approach for both elective and emergent repair. The preoperative technical considerations include assessment of incarceration and potential for extensive adhesiolysis, size of defect, and atypical hernia locations. Preoperative considerations include weight loss and lifestyle modification. There are multiple methods of fascial defect closure and mesh fixation that the surgeon may consider via a laparoscopic approach, making it adaptable to varying clinical scenarios and anatomic challenges. Compared with open repair laparoscopic repair is associated with reduced surgical wound site infection, and compared with robotic repair outcomes are similar.

Does Concomitant Umbilical Hernia Repair Increase the Risk of Complications in Abdominoplasty? A Propensity Score Matched Analysis

BACKGROUND

Patients seeking cosmetic abdominoplasty often have umbilical hernias. Optimal management and safety of concomitant umbilical hernia repair with abdominoplasty is not well described.

OBJECTIVES

The goal of this study was to compare complication rates following abdominoplasty with or without umbilical hernia repair.

METHODS

A retrospective propensity score matched cohort study of patients who underwent an abdominoplasty at Massachusetts General Hospital was performed. Direct umbilical hernia repair was performed by making a fascial slit inferior or superior to the umbilical stalk. The fascial edges were approximated with up to three 0-Ethibond sutures (Ethicon, Raritan, NJ) from the preperitoneal or peritoneal space. Propensity score matching was used to adjust for confounding variables.

RESULTS

The authors identified 231 patients with a mean [standard deviation] age of 46.7 [9.7] years and a mean BMI of 25.9 [4.4] kg/m2. Nine (3.9%) had diabetes, 8 (3.5%) were active smokers, and the median number of previous pregnancies was 2. In total, 223 (96%) had a traditional abdominoplasty, whereas 8 (3.5%) underwent a fleur-de-lys approach. Liposuction was performed on 90%, and 45.4% underwent simultaneous breast or body contouring surgery. The overall complication rate was 6.9%. Propensity scores matched 61 pairs in each group (n = 122) with closely aligned covariates. There was no significant difference in total complication rates between abdominoplasty alone vs abdominoplasty with hernia repair. There were no cases of skin necrosis or umbilical necrosis in either group.

CONCLUSIONS

Performing umbilical hernia repair with abdominoplasty is safe when utilizing the technique reported in this series.

Endoscopic treatment of diastasis recti: Training method and literature review

INTRODUCTION

Endoscopic treatment of diastasis rectus abdominis offers the possibility of correcting the condition without complete abdominoplasty. The purpose of this study was to develop a training method on fresh cadavers models based on a literature review on this surgery.

MATERIAL AND METHODS

The endoscopic procedure considered involved the insertion of a 10mm suprapubic trocar and of 5mm trocars in each iliac fossae. The muscle suture is done using running barbed suture. The surgery was performed on eight fresh cadavers to estimate the learning curve for this intervention, which was estimated with the CUSUM method. A systematic literature review in the PubMed database was performed, and 20 articles that met the inclusion criteria were analyzed.

RESULTS

The learning curve threshold was reached after 6 operations and can be separated into two phases. The most common complication of this surgery is seroma, it is encountered in 3 to 27% of cases according to the studies. Diastasis recurrence is rare, occurring in less than 2% of cases. In comparison, open surgical treatment of diastasis recti is associated with a higher risk of hematoma, skin necrosis and longer operating times. Recurrence rates are similarly low after open and endoscopic repair. Mesh reinforcement is indicated in cases of diastasis wider than 5cm, diastasis recurrence, severe musculoaponeurotic laxity, or hernia larger than 1cm.

CONCLUSION

The data in the literature indicate that laparoscopic surgery is an efficient and safe approach to correct diastasis of the rectus muscles and can be offered by plastic surgeons to selected patients.

A Novel Robotic Approach for the Repair of Abdominal Wall Hernias With Concomitant Diastasis Recti: Outcomes and Long-term Follow-up

BACKGROUND

Diastasis recti (DR) is defined as the separation of the rectus muscles as a result of the linea alba thinning and stretching. The purpose of this study was to evaluate the long-term outcomes of a new technique, robotic rectus abdominis medialization (rRAM), for DR repair with a concomitant ventral hernia.

METHODS

Patients who underwent rRAM for repair of DR and a concomitant ventral hernia were identified between January 2015 and December 2020. The results are from a single surgeon at a single institution.

RESULTS

A total of 40 patients were identified, 29 of which were female. The mean age was 43 years, the mean body mass index was 27 kg/m 2 , and the mean inter-rectus distance was 6 cm based on available preoperative imaging. The median postoperative length of stay was 1 day, and the median follow-up time was 1 month. Within 30 postoperative days, 3 patients were re-admitted and 5 developed complications, of which 1 required operative re-intervention for seroma. Beyond 30 days, 3 patients required operative re-intervention most commonly for persistent pain from suture material. On the basis of computed tomography scans performed at a mean of 30 months after the date of service, the mean postoperative inter-rectus distance was 1 cm; 1 patient had DR recurrence, and 1 patient developed a new incisional hernia without DR recurrence. There was no hernia recurrence.

CONCLUSIONS

rRAM is a safe and effective technique for DR repair with a concomitant ventral hernia. Further studies are needed to determine how outcomes from this robotic approach compare with those from different robotic, laparoscopic, and open techniques.

Endoscopic Mini-or Less-Open Sublay Operation (E/MILOS) in ventral hernia repair: a minimally invasive alternative technique

The ideal ventral hernia surgical repair is still in discussion1. The defect closure with a mesh-based repair is the base of surgical repair, in open or minimally invasive techniques2. The open methods lead to a higher surgical site infections incidence, meanwhile, the laparoscopic IPOM (intraperitoneal onlay mesh) increases the risk of intestinal lesions, adhesions, and bowel obstruction, in addition to requiring double mesh and fixation products which increase its costs and could worsen the post-operative pain3-5. The eTEP (extended/enhanced view totally intraperitoneal) technique has also arisen as a good option for this hernia repair. To avoid the disadvantages found in classic open and laparoscopic techniques, the MILOS (Endoscopically Assisted Mini or Less Open Sublay Repair) concept, created by W. Reinpold et al. in 2009, 3 years after eTEP conceptualization, allows the usage of bigger meshes through a small skin incision and laparoscopic retro-rectus space dissection, as the 2016 modification, avoiding an intraperitoneal mesh placement6,7. This new technique has been called E-MILOS (Endoscopic Mini or Less Open Sublay Repair)8. The aim of this paper is to report the E-MILOS techniques primary experience Brazil, in Santa Casa de Misericórdia de São Paulo.

Management of diastasis recti during ventral hernia repair: an analysis of the abdominal core health quality collaborative

PURPOSE

Advancements of minimally invasive techniques leveraged routine repair of concomitant diastasis recti (DR), as those approaches facilitate fascial plication and wide mesh overlap while obviating skin incision and/or undermining. Nevertheless, evidence on the value of such intervention is lacking. We aimed to investigate the management and outcomes of concomitant DR during ventral hernia repair (VHR + DR) from surgeons participating in the Abdominal Core Health Quality Collaborative (ACHQC).

METHODS

Patients who have undergone VHR + DR with a minimum 30-day follow-up complete were identified. Outcomes of interest included operative details, surgical site occurrences (SSO), medical complications, and readmissions.

RESULTS

169 patients (51% female, median age 46, median body mass index 31 kg/m2) were identified. Most hernias were primary (64% umbilical, 28% epigastric). Median hernia width was 3 cm (IQR 2-4) and median diastasis width and length were 4 cm (IQR 3-6) and 15 cm (IQR 10-20), respectively. Most operations were robotic (79%), with a synthetic mesh (92%) placed as a sublay (72%; 59% retromuscular, 13% preperitoneal). DR was repaired with absorbable (92%) and running suture (93%). Considering our cohort's relatively small diastasis and hernia size, a high rate of transversus abdominis release was noted (14.7%). 76% were discharged the same day and the 30-day readmission rate was 2% (2 ileus, 1 pneumonia). SSO rate was 4% (6 seromas, 1 skin necrosis) and only one patient required a procedural intervention.

CONCLUSIONS

ACHQC participating surgeons usually perform VHR + DR robotically with a retromuscular synthetic mesh and close the DR with running absorbable sutures. Short-term complications occurred in approximately 6% of patients and were mainly managed without interventions. Larger studies with longer-term follow-up are needed to determine the value of VHR + DR.

Endoscopic Mini or Less Open Sublay Repair (E/MILOS) na correção das hérnias ventrais: uma alternativa técnica minimamente invasiva

RESUMO O tratamento cirúrgico ideal para correção das hérnias ventrais ainda é motivo de grande discussão1. O fechamento do defeito associado a utilização de telas para reforço da parede abdominal são passos fundamentais da terapia cirúrgica, podendo ser realizados tanto pela via aberta quanto pelas técnicas minimamente invasivas2. A via aberta apresenta maiores taxas de infecção de sítio cirúrgico, enquanto o reparo laparoscópico IPOM (intraperitoneal onlay mesh) acarreta um risco aumentado de lesões intestinais, aderências e obstruções intestinais, além de requerer uso de telas de dupla face e dispositivos de fixação que encarecem o procedimento e não raro aumentam a dor no pós-operatório3-5. A técnica eTEP (extended/enhanced view totally extraperitoneal), tem ganhado importância, mostrando-se uma boa opção para a correção das hérnias ventrais também2. A fim de se evitar as desvantagens das técnicas abertas e laparoscópicas “clássicas” o conceito MILOS (Endoscopically Assisted Mini or Less Open Sublay Repair), desenvolvido por W. Reinpold et al. em 2009, 3 anos antes do advento do eTEP, possibilita ao cirurgião o uso de telas de grandes dimensões no plano retromuscular através de uma pequena incisão na pele e dissecção laparoscópica deste espaço, conforme modificação realizada em 2016, evitando a colocação de uma tela no espaço intraperitoneal6-7. Esta nova técnica passou a se chamar EMILOS (Endoscopic Mini or Less Open Sublay Repair)8 Este artigo tem como objetivo relatar nossa experiência inicial no emprego da técnica E-MILOS no Brasil, na Santa Casa de Misericórdia de São Paulo.

Severe rectus diastasis with midline hernia associated in males: high recurrence in mid-term follow-up of minimally invasive surgical technique

PROPOSE

The present study aimed to assess clinical results, in terms of postoperative pain, functional recovery and recurrence rates of FESSA (Full Endoscopic Suprapubic Subcutaneous Access) technique compared to endoscopic anterior rectus sheaths plication and mesh, in male patients with midline ventral or incisional hernias and severe rectus diastasis (SRD) associated. Secondary aims were to identify intra- and postoperative complications associated with each technique.

METHODS

Male patients with midline ventral or incisional hernia and severe rectus diastasis were included in a prospectively maintained databased and retrospectively analyzed from January 2017 to December 2020. From January 2017 to January 2019, male patients underwent to anterior rectus sheaths plication (ARSP) (Control group). From January 2019 to December 2020, male patients underwent to FESSA technique (FT) (Case group).

RESULTS

53 patients were finally included. 28 patients (52%) underwent to FT and 25 patients (48%) to ARSP. Regarding intraoperative complications, no significant differences were identified between the groups. Hospital stay was significantly improved in FT group when compared to ARSP group. No significant differences in terms of postoperative seroma or hematomas, were shown. FT group showed significantly less pain on 1st, 7th and 30th postoperative days than ARSP group. Functional recovery was significantly improved in FT group compared to ARSP group on the 30th day and no differences were observed on the 180th day after surgery. The mean follow-up was 17.3 ± 2.6 months in FT group and 24 ± 3 months in ARSP group. During the follow-up, 1(3%) and 9 (36%) diastasis recurrences were identified respectively, with significant differences in favor of FT group.

CONCLUSION

In males with SRD and symptomatic midlines hernias, ARSP with onlay mesh placement shows high diastasis recurrence rate in mid-term follow-up. We propose FESSA technique in those patients, which decreases the excessive midline tension, improving the postoperative pain, functional recovery and recurrence rate, without increasing postoperative complications.

Post-partum abdominal wall insufficiency syndrome (PPAWIS): lessons learned from a single surgeon's experience based on 200 cases

Background

Post-partum abdominal wall insufficiency (PPAWI) with rectus diastasis is present in over 30% of women after pregnancy. Little is known about how PPAWI affects the social, sexual life and self-esteem of patients. This study was designed to evaluate the safety of onlay mesh combined with abdominoplasty and its impact on the well-being of the patients.

Method

Two hundred patients with PPAWI underwent surgery with onlay mesh and abdominoplasty. The safety of the procedure was assessed by postoperative complications, time of hospitalization and time of drainage. Before the operation and 6 months later, a questionnaire asking about the patient’s sexual and social life and the presence of back pain was completed. The final cosmetic effect was assessed separately.

Results

The onlay procedure with abdominoplasty was found to be safe and fast. The mean operation time was 82 min, and the drainage time was 2.1 days. In this group < 2% postoperative complications were noted. There were no recurrences within the 6 month. Significant improvements in social and sexual life and the level of self-esteem were noted. Back pain was relieved or minimalized in all patients. The final cosmetic effect was insufficient for 2 patients (1%).

Conclusion

PPAWI can be treated safely with onlay mesh and abdominoplasty. The patients’ symptoms were strongly correlated with the morphological status of the front abdominal wall and improved after the procedure. Describing the psychological and social consequences of PPAWI should lead the surgical societies to propose a definition of a new disease called PPAWIS (post-partum abdominal wall insufficiency syndrome).
