Nonabsorbable Barbed Sutures for Diastasis Recti. A Useful Device with Unexpected Risk: Two Case Reports

The introduction of nonabsorbable barbed sutures in plastic surgery has allowed the achievement of significant results in terms of efficacy and short- and long-term outcomes. However, a nonabsorbable material with no antibacterial coating could act as a substrate for subclinical bacterial colonization and thereby determine recurrent subacute and chronic infective-inflammatory processes. The authors report a clinical experience of subacute infectious complications after two cases of diastasis recti surgical correction. The authors present a two-case series in which a nonabsorbable barbed suture was used for the repair of diastasis recti. The postoperative course was complicated by surgical site infection. The origin of the infectious process was clearly localized in the fascial suture used for diastasis correction. The suture was colonized by bacteria resulting in the formation of multiple granulomas of the abdominal wall a few months postoperatively. In both the reported cases, the patients partially responded to the antibiotic targeted therapy and reoperation was required. The microbiological analyses confirmed the colonization of sutures by Staphylococcus aureus . Barbed nonabsorbable sutures should be avoided for diastasis recti surgical correction to minimize the risk of infectious suture-related complications. The paper's main novel aspect is that this is the first clinical report describing infectious complications after surgical correction of diastasis recti with barbed polypropylene sutures. The risk of microbiological subclinical colonization of polypropylene suture untreated with antibacterial coating, therefore, should be taken into account.

Do Absorbable Sutures Work for Rectus Diastasis Repair in Abdominoplasty Patients?

Background

The standard treatment for rectus diastasis is rectus sheath plication during abdominoplasty. Lasting correction of diastasis is essential, but there is currently a debate as to whether absorbable or nonabsorbable rectus plication achieves a lower rate of recurrence.

Objectives

The goal of this study is to assess long-term patient outcomes and the recurrence of rectus diastasis after plication with long-lasting absorbable sutures.

Methods

A retrospective study of abdominoplasties performed by the senior author between 2018 and 2022 was performed. Only female patients with >6 months of follow-up were included. Plication of the rectus muscles was performed with a combination of interrupted, buried, figure of eight #0 polydioxanone suture and running #0 Maxon (Covidien, Mansfield, MA). Outcomes were assessed by physical examination at postoperative visits. A retrospective chart review was used to obtain demographic and perioperative information.

Results

Seventy-one patients underwent abdominoplasty with an average follow-up of 21.1 months. The average age was 43 years, and the average BMI was 27 kg/m2. Correction of rectus diastasis was performed using absorbable sutures in all patients with no recurrence of diastasis in any patient (0% diastasis recurrence rate). Complications included delayed wound healing (11%), seroma (8.5%), hematoma (2.8%), and deep vein thrombosis/pulmonary embolism (2.8%). No patients needed reoperation.

Conclusions

Abdominal wall plication using a double-layered, long-lasting absorbable suture closure is a safe, reliable, and effective method to address rectus diastasis during abdominoplasty. Our technique achieved no recurrence of diastasis in any patient and a low complication profile.

Clinical and Radiological Evaluation of Onlay Mesh Abdominoplasty in Obese Multiparous Patients with Moderate-to-Severe Rectus Diastasis

BACKGROUND

Women with multiple pregnancies often experience abdominal protrusion and/or a lax abdominal wall. Various open surgical techniques have been developed to address rectus diastasis in abdominoplasty, ranging from suture plication to mesh reinforcement. This study aims to compare the clinical and radiological changes between traditional abdominal plication and the addition of non-absorbable mesh for rectus muscle (RM) diastasis repair in terms of function, postoperative outcome, and recurrence.

PATIENTS AND METHOD

This prospective retrospective study involved 63 women who underwent cosmetic tummy tuck surgery and met certain eligibility criteria. Patients with only mild diastasis recti, midline hernia, contraindications for major surgery, recent smoking history, or refusal of mesh augmentation were excluded. Clinical examination for abdominal protrusion or bulging and CT imaging was performed to check for recurrence of diastasis recti. The study included 33 patients who underwent mesh repair and 30 who underwent traditional abdominal plication. Follow-up was conducted after 1 year using CT and a questionnaire to assess various factors compared to preoperative measurements, with overall satisfaction rated on a 10-point Likert scale.

RESULTS

There was no significant difference in demographic data between the two groups. Patients who underwent mesh repair had a slightly longer hospital stay and drain duration. The average waist circumference decreased in both groups without any statistically significant difference. Objective CT showed significant reductions in both groups in inter-rectus distance, RM width and circumference, and intra-abdominal circumference compared to preoperative values. All patients expressed satisfaction with scar quality and umbilicus aesthetics, and no recurrence was detected either clinically or radiologically during the follow-up period.

CONCLUSION

Comprehensive preoperative assessment and imaging techniques like ultrasound and CT scans allow surgeons to detect postpartum changes in the abdominal wall. Mesh reinforcement may be indicated for diastasis above 4 cm in obese multiparous females. Thorough preoperative evaluation permits customized surgical plans to optimally restore abdominal wall anatomy and function.

Alternative Abdominal Wall Plication Techniques: A Review of Current Literature

Abdominoplasty is one of the most common procedures performed in plastic surgery. By removing redundant skin and fat tissue, body contouring narrows the waist and achieves a naturally flattened appearance. To achieve this, one technique frequently utilized is plication of the abdominal rectus sheath. Although abdominal wall plication is commonly performed during abdominoplasty, there is a lack of consensus regarding which plication method provides the best outcomes. Each variation addresses some of the common intraoperative and postoperative complications of abdominoplasty. These include extended operating time, rupture of the plication, epigastric bulging, and patient postoperative dissatisfaction. Many plication techniques have been described in the literature, but no single technique has been adopted by plastic surgeons as the gold standard. Here we present a narrative comparison of current published literature reporting novel or modified abdominoplasty plication techniques. This includes diagrams of each procedure, sutures utilized, and key concepts of each plication technique. Discussion regarding how these modifications change operating time, alter epigastric bulging, and improve the ability to narrow the waist is provided. The purpose of this paper is to provide a concise source document for plastic surgeons to reference when choosing a plication method to use during abdominoplasty.

Simple plication alleviates physical symptoms in patients with post-gestational rectus diastasis

PURPOSE

To evaluate our surgery for post-gestational rectus abdominis muscle diastasis using slowly absorbable monofilament suture and eight weeks of abdominal binder in terms of recurrence rate, complications, and effect on patients' physical and cosmetic complaints.

METHOD

In a retrospective cohort study, all 44 patients operated between 2014 and 2020 were invited to a follow-up using ultrasound, clinical examination, and questionnaires regarding symptoms before and after surgery.

RESULTS

89% of invited patients participated, with a median follow-up of 36 months. There was one recurrence caused by severe postoperative nausea and vomiting, which was the most common complication. Most procedures were safe, but two patients experienced Clavien-Dindo grade 3 complications. Patients reported feeling limited or taking precautions after surgery for a median of 8.5 months. Of all included patients, four responded that the operation did not alleviate their primary complaint. The remaining 35 patients (90%) experienced complete or partial alleviation of their primary complaints and would undergo the procedure again if needed.

CONCLUSION

Post-gestational diastasis recti can be associated with a large number of physical symptoms and functional complaints and can safely be operated using a single running plication of the anterior rectus fascia with a slowly absorbable suture, with fair cosmetic results, excellent effect on symptoms, few complications and high levels of patient satisfaction. Future research must determine which symptoms and findings should indicate surgery.

Do Abdominal Binders Prevent Seroma Formation and Recurrent Diastasis Following Abdominoplasty?

BACKGROUND

For decades, the postoperative wearing of abdominal binders has been suggested to reduce dead space and prevent mobilization of the musculoaponeurotic layer in an attempt to decrease the risk of seroma formation and recurrent diastasis.

OBJECTIVES

This study sought to evaluate whether the postoperative wearing of an abdominal binder provides any additional contribution to the reduction of either seroma formation or recurrent diastasis recti when abdominoplasty is performed with quilting sutures.

METHODS

Thirty-four women undergoing abdominoplasty were randomized into 2 groups: the binder group (n = 16) wore abdominal binders during the postoperative period, whereas the control group (n = 18) did not. Ultrasound examination was performed on postoperative days 7 and 14 to assess seroma formation and at 6 months postoperatively to assess recurrence of diastasis recti. A t test for independent samples was applied to compare means between 2 numeric variables. Generalized estimation equation models were used to evaluate seroma volume at different time points for the 2 groups.

RESULTS

No significant differences in seroma volume were found between groups on postoperative days 7 (P = 0.830) and 14 (P = 0.882). Seven cases of subclinical recurrent diastasis were observed by ultrasound examination in the supraumbilical (4 cases) and infraumbilical regions (3 cases), but without significant differences (P = 1.000) between the 2 groups. Recurrent diastasis was not detected during physical examinations.

CONCLUSIONS

The postoperative wearing of abdominal binders was not effective in preventing either seroma formation or recurrent diastasis following abdominoplasty with quilting sutures.

The Effect of Quilting Sutures on the Tension Required to Advance the Abdominal Flap in Abdominoplasty

BACKGROUND

Quilting sutures attaching the abdominal flap to the aponeurosis contribute to the prevention of seroma formation following abdominoplasty. The sutures distribute the tension over the subcutaneous tissue along the flap length, theoretically decreasing tension at the distal (cutaneous) end of the flap. This is expected to reduce the risks of necrosis, dehiscence, and enlarged or hypertrophic scars.

OBJECTIVES

This study sought to verify whether quilting sutures decrease the tension required to advance the dermal-fat flap in abdominoplasty.

METHODS

Thirty-four women undergoing abdominoplasty with quilting sutures participated in the study. The tensile force required for flap advancement was measured with a digital force gauge before and after placement of quilting sutures and then compared. Differences in tensile force were tested for correlations with BMI, age, weight of flap tissue removed, number of previous pregnancies, and postoperative complications, including seroma formation, hematoma, necrosis, dehiscence, and enlarged or hypertrophic scars.

RESULTS

A mean reduction in tension of 27.7% was observed at the skin suture after the placement of quilting sutures (P < 0.001). No significant correlation was found between reduced flap tension and BMI, age, weight of tissue removed, or number of births. One case of seroma formation and 2 cases of enlarged scars were observed, but no case of hematoma, necrosis, or wound dehiscence was detected.

CONCLUSIONS

The use of quilting sutures to attach the abdominal flap to the aponeurosis of the anterior abdominal wall reduced tension at the advancing edge of the flap in abdominoplasty.

A Proposed Classification and Treatment Algorithm for Rectus Diastasis: A Prospective Study

Background

This study presents a classification system and treatment method to correct Rectus diastasis (RD) during abdominoplasty.

Materials and methods

One hundred and sixty seven patients undergoing abdominoplasty were enrolled between April 2014 and January 2018. Forty-three patients did not present with RD and were excluded from the analysis. Mean age was 40.32 years, mean BMI was 23.84, and minimum follow-up was 24 months. A four-type (A: mild 2–3cm, B: moderate 3–5cm, C: severe 5–7cm, and D: very severe 7–9cm) classification system is described. A different treatment method is performed in each category using continuous and interrupted absorbable sutures. Postoperatively patients filled up a questionnaire that involved the level of pain, the postoperative day they performed specific indoor/outdoor activities, and the evaluation of the aesthetic result.

Results

No statistically significant differences were observed between the four RD types regarding pain, complications, and return to specific activities. All types of RD had the same low rate complication profile. The seroma rate was 0.81%. The infection rate was 0.81%, and the thromboembolism and the pneumonic embolism rate was 0%. After 2–6 years of follow-up no clinical recurrence of rectus diastasis was observed. All reoperations (14.52%) were performed due to scar deformities. Mean pain score levels were very low (<1.5) and within a week most patients returned to specific indoor and outdoor activities. Most patients were extremely satisfied with the results.

Conclusions

In this article, we present an updated classification system and treatment protocol to provide surgeons a safe and standardized method that produces high-quality aesthetic results.

Management of diastasis of the rectus abdominis muscles: recommendations for swedish national guidelines

BACKGROUND

Diastasis of the rectus abdominis muscle is a common condition. There are no generally accepted criteria for diagnosis or treatment of diastasis of the rectus abdominis muscle, which causes uncertainty for the patient and healthcare providers alike.

METHODS

The consensus document was created by a group of Swedish surgeons and based on a structured literature review and practical experience.

RESULTS

The proposed criteria for diagnosis and treatment of diastasis of the rectus abdominis muscle are as follows: (1) Diastasis diagnosed at clinical examination using a caliper or ruler for measurement. Diagnostic imaging by ultrasound or other imaging modality, should be performed when concurrent umbilical or epigastric hernia or other cause of the patient's symptoms cannot be excluded. (2) Physiotherapy is the firsthand treatment for diastasis of the rectus abdominis muscle. Surgery should only be considered in diastasis of the rectus abdominis muscle patients with functional impairment, and not until the patient has undergone a standardized 6-month abdominal core training program. (3) The largest width of the diastasis should be at least 5 cm before surgical treatment is considered. In case of pronounced abdominal bulging or concomitant ventral hernia, surgery may be considered in patients with a smaller diastasis. (4) When surgery is undertaken, at least 2 years should have elapsed since last childbirth and future pregnancy should not be planned. (5) Plication of the linea alba is the firsthand surgical technique. Other techniques may be used but have not been found superior.

DISCUSSION

The level of evidence behind these statements varies, but they are intended to lay down a standard strategy for treatment of diastasis of the rectus abdominis muscle and to enable uniformity of management.

Mesh Repair of Rectus Diastasis for Abdominoplasty is Safer than Suture Plication

Concerns regarding infection, extrusion, and pain have traditionally precluded the use of mesh to treat severe rectus diastasis during abdominoplasty in the United States. We describe a mesh abdominoplasty technique, and we hypothesize that the complication rate using mesh is greater than the complication rate of suture plication.

METHODS

Inclusion criteria for mesh abdominoplasty were patients who (1) had retrorectus planar mesh for repair of rectus diastasis, (2) did not have concurrent ventral hernia, and (3) underwent skin tailoring. Patients who underwent rectus plication with suture, and met criteria 2 and 3 above were included in a sample of consecutive standard abdominoplasty patients. The primary endpoint was surgical site occurrence at any time after surgery, as determined with review of their office and hospital medical records. Secondary endpoints included surgical site infection, revision rates, postoperative course, and aesthetics assessed with their last set of office photographs.

RESULTS

Surgical site occurrence rate was 0% of the 40 patients in the mesh group and 19% of the 37 patients in the standard group (P = 0.005); rates of soft-tissue revision were 23% in the mesh group and 27% in the standard group (P = 0.84). As to aesthetics, the mesh abdominoplasty patients had mean statistically lower preoperative scores in comparison with the standard plication group (65.8 ± 11.6 versus 70.3 ± 11.4, P = 0.0013). The mesh group had a statistical improvement to 75.9 ± 12.6 (P < 0.0001), whereas the standard plication group improved to 82.5 ± 11.4 (P < 0.0001).

CONCLUSIONS

Retrorectus mesh placement in a cohort of patients with severe rectus diastasis had a complication rate lower than that seen in a cohort of patients with less severe rectus diastasis, therefore negating our original hypothesis. This was done without compromising aesthetic improvement.

Surgical techniques for repair of abdominal rectus diastasis: a scoping review

Rectus diastasis is characterized by widening and laxity of the linea alba, causing the abdominal content to bulge. Rectus diastasis is treated either conservatively with physiotherapy, or surgically, surgical treatment showing especially convincing results. The primary aim of this study was to describe surgical techniques used to correct abdominal rectus diastasis. Secondary, we wished to assess postoperative complications in relation to the various techniques. A systematic scoping review was conducted and reported according to the PRISMA-ScR statement. PubMed, Embase, and Cochrane Library were searched systematically. Studies were included if they described a surgical technique used to repair abdominal rectus diastasis, with or without concomitant ventral hernia. Secondary outcomes were recurrence rate and other complications. A total of 61 studies were included: 46 used an open approach and 15 used a laparoscopic approach for repair of the abdominal rectus diastasis. All the included studies used some sort of plication, but various technical modifications were used. The most common surgical technique was classic low abdominoplasty. The plication was done as either a single or a double layer, most commonly with permanent sutures. There were overall low recurrence rates and other complication rates after both the open and the laparoscopic techniques. We identified many techniques for repair of abdominal rectus diastasis. Recurrence rate and other complication rates were in general low. However, there is a lack of high-level evidence and it is not possible to recommend one method over another. Thus, further randomized controlled trials are needed in this area.

A new minimally invasive technique for the repair of diastasis recti: a pilot study

Background

Diastasis recti is an abdominal wall defect that occurs frequently in women during pregnancy. Patients with diastasis can experience lower back pain, uro-gynecological symptoms, and discomfort at the level of the defect. Diastasis recti is diagnosed when the inter-rectus distance is > 2 cm. Several techniques, including both minimally invasive and open access surgical treatment, are available. Abdominoplasty with plication of the anterior rectus sheath is the most commonly used, with the major limitation of requiring a wide skin incision. The new technique we propose is a modification of Costa’s technique that combines Rives–Stoppa principles and minimally invasive access using a surgical stapler to plicate the posterior sheaths of the recti abdominis.

Methods

It is a fully laparoscopic technique. The pneumoperitoneum is induced from a sovrapubic trocar, placed using an open access technique. The posterior rectus sheath is dissected from the rectus muscle using a blunt dissector to create a virtual cavity. The posterior sheets of the recti muscles are plicated using an endo-stapler. A mesh is then placed in the retromuscular space on top of the posterior sheet without any fixation. Using a clinical questionnaire, we analyzed the outcomes in 74 patients who underwent minimally invasive repair for diastasis of the rectus abdominis sheath.

Results

Seventy-four patients (9 men and 65 women) were treated using this technique. Follow-up was started two months after surgery. All procedures were conducted successfully. There were no major complications or readmissions. No postoperative infections were reported. There were two recurrences after six months. There was a significant reduction in symptoms.

Conclusions

This new method is feasible and has achieved promising results, even though a longer follow-up is needed to objectively assess this technique.

Autologous Dermal Mesh in Severe Postpregnancy Recti Muscles Diastasis

INTRODUCTION

The severe postpregnancy diastasis of recti muscles causes a biomechanical alteration of the statics of the trunk and an unaesthetic bulging of the abdominal wall. This is always combined with cutaneous and subcutaneous excess, which is different on a case-by-case basis. There is not a consensus on the best way to treat it. The anterior sheath plication is the mostly used surgical technique, and many surgeons believe that the use of mesh is necessary in the cases of severe diastasis. The authors here report the outcomes of the use of dermal automesh in the retromuscular layer.

MATERIALS AND METHODS

Between January 2015 and December 2019, a retrospective study on 101 patients was conducted. All patients underwent the repairment of the diastasis recti with transversalis sheath plication and dermal automesh reinforcement in the sublay fashion. In addition, all the patients had an abdominal wall ultrasound before the operation and an ultrasound after 1 month, 3 months, 6 months, 1 year and every year afterward. The median follow-up was 32.5 months RESULTS: No major complications, such as infections, extrusions, respiratory diseases or thrombosis, were reported. The follow-up abdominal wall ultrasound reported the absence of muscle recti diastasis in all patients. All patients were completely satisfied with the final result.

CONCLUSION

In postpregnancy women, the severe recti muscles diastasis dermal automesh repair is safe and effective. The dermal graft is easy to handle, has demonstrated comparable tensile strength to alloplastic mesh and is available in abdominoplasty or miniabdominoplasty from the excised skin.

Treatment of rectus diastasis: should the midline always be reinforced with mesh? A systematic review

BACKGROUND

Two main trends are described for the treatment of diastasis recti: plication versus midline mesh reinforcement. Indications for these procedures have not been clearly described. This study reviewed the outcomes in the treatment of rectus diastasis with plication versus mesh by the assessment of durability, complications, and patient-reported outcomes.

MATERIALS AND METHODS

A systematic review of literature on the treatment of diastasis recti was performed searching through PubMed, Embase, Web of Science, and Cochrane databases. This resulted in 53 eligible articles and predefined inclusion criteria led to the selection of 24 articles. Primary outcomes included recurrence and perioperative complications and secondary outcomes were defined as patient satisfaction, chronic pain, and quality of life.

RESULTS

A total of 931 patients were surgically treated for rectus divarication (age range: 18 - 70 years). The most frequently noted comorbidity was obesity and 10.6 percent were smokers. Recurrence was reported in 5 percent of the patients. The most frequent complication was seroma (7 percent), followed by abdominal hypoesthesia (6 percent), and surgical site infection (2 percent). Chronic pain was reported in 4 percent of the patients. Satisfaction was assessed subjectively in the majority of patients and was generally rated as high. Follow-up period ranged from 3 weeks to 20 years.

CONCLUSIONS

Durability, safety, and high patient satisfaction support surgical correction of rectus diastasis and could not favor a treatment method. Inter-rectus distance could not be identified as the indicator for technique, which emphasizes that other factors might add to the entity of abdominal wall protrusion more than previously thought.

Long-term follow-up after surgical repair of abdominal rectus diastasis: A Prospective Randomized Study

BACKGROUND

Abdominal rectus diastasis can lead to functional disability. There is no consensus regarding treatment. This was a prospective study on patients randomized to surgery using either Quill self-retaining sutures or retromuscular mesh for abdominal rectus diastasis repair. The primary aim of the study was to compare long-term recurrence after surgery. Secondary aims were abdominal muscle strength, pain, and quality of life.

METHODS

A total of 57 patients were eligible and 52 were investigated. A routine 1-year follow-up ruled out any patient with recurrence and this was followed up by clinical examination for recurrence and assessment of the secondary outcomes a median of 5 years (3.8-6.5 years) after surgery. Quality of life was assessed using the Short Form-36 questionnaire. Pain related to activity was evaluated using the Ventral Hernia Pain Questionnaire.

RESULTS

No recurrence of abdominal rectus diastasis was found. Significant improvements were seen between index surgery and long-term follow-up in all domains of Short Form-36. There were no significant differences in quality of life or self-reported muscle strength between the two surgical groups. Long-term pain remained unchanged compared to that at the 1-year follow-up. "Pain this week" had decreased significantly at long-term follow-up compared to prior to surgery (mesh p = 0.009, Quill p = 0.003).

CONCLUSIONS

No recurrence of abdominal rectus diastasis appeared. There was no difference in quality of life or long-term pain between the two surgical groups. Implantation of retromuscular mesh entails more extensive surgery implying potentially higher risk for complications. This leads us to recommend reconstruction with double-row self-retaining sutures for the repair of abdominal rectus diastasis in patients with functional disability.

This leads us to recommend reconstruction with double-row self-retaining sutures for the repair of abdominal rectus diastasis in patients with functional disability.

Treatment Options for Abdominal Rectus Diastasis

Background: Abdominal rectus diastasis is a condition where the abdominal muscles are separated by an abnormal distance due to widening of the linea alba causing the abdominal content to bulge. It is commonly acquired in pregnancies and with larger weight gains. Even though many patients suffer from the condition, treatment options are poorly investigated including the effect of physiotherapy and surgical treatment. The symptoms include pain and discomfort in the abdomen, musculoskeletal and urogynecological problems in addition to negative body image and impaired quality of life. The purpose of this review was to give an overview of treatment options for abdominal rectus diastasis. Results: The first treatment step is physiotherapy. However, evidence is lacking on which regimen to use and success rates are not stated. The next step is surgery, either open or laparoscopic, and both surgical approaches have high success rates. The surgical approach includes different plication techniques. The recurrence and complication rates are low, complications are minor, and repair improves low back pain, urinary incontinence, and quality of life. Robotic assisted surgery might become a possibility in the near future, but data are still lacking. Conclusions: Evidence on what conservatory treatment to use is sparse, and more research needs to be done. Both open and laparoscopic surgery have shown positive results. Innovative treatment by robotic assisted laparoscopic surgery has potential, however, more research needs to be done in this area as well. An international guideline for the treatment of rectus diastasis could be beneficial for patients and clinicians.

Abdominal Wall Plication and Correction of Deformities of the Myoaponeurotic Layer: Focusing on Materials and Techniques Used for Synthesis

The different types of sutures utilized in plications and for correction of diastasis during abdominoplasty are reviewed and discussed. Because correction of abdominal deformities also involves fascia and muscle advancement, this review also covers the suture materials used in muscle advancement. The selection of specific techniques to treat different types of abdominal wall deformity is also considered. This is important, because the outcome when correcting these deformities depends not only on suture materials but also on employing the optimum technique. A PubMed/Medline search was performed with the following search terms: rectus diastasis, diastasis recti, diastasis recti abdominis, correction of rectus diastasis, abdominoplasty. Relevant articles identifying the type of suture (rapidly absorbable, slowly absorbable, nonabsorbable), monofilament or multifilament sutures, antibiotic-coated sutures, and barbed sutures were evaluated. In addition, articles about surgical technique comparing continuous and interrupted sutures, in both the anterior and posterior aponeurosis, to correct rectus diastasis are discussed. Efficacy of suture materials was evaluated based on the long-term results and recurrence rates reported in these articles. The current literature provides sufficient data to recommend a single-layer continuous suture, with slowly absorbable sutures of 0 polydioxanone or 2-0 nylon, for correction of abdominal diastasis. An interrupted triangular suture is a good alternative to correct the vertical elongation of the myoaponeurotic layer that occurs after pregnancy.

Endo-laparoscopic reconstruction of the abdominal wall midline with linear stapler, the THT technique. Early results of the first case series

Background

Midline primary hernias represent one of the most frequent abdominal wall defects in the adult population and in almost half of the cases they are associated with a rectus abdominis diastasis (RAD). Despite the high incidence of these defects there is currently no consensus in the literature on what is the preferred surgical technique for treatment. In this paper we present the first case series treated with an innovative technique that aims to repair the defects of the midline and RAD, while combining the advantages of the sublay Rives-Stoppa technique with those of the minimally-invasive surgery.

Methods

Between January 2018 and May 2018, 14 patients underwent endo-laparoscopic reconstruction of the midline. The surgery was performed under general anaesthesia through a 4 cm periumbilical incision with single port technique. The rectus abdominis sheaths were joined together and sutured lengthwise using a linear stapler. A tailor-made synthetic prosthesis was positioned in the retromuscular space.

Results

All cases had RAD with a mean width of 5.3 cm in the supraumbilical space. None of the surgeries needed laparotomic conversion. The average duration of the surgery was 80 min. The hospitalization was in all cases one day. The average follow-up period was 6 months. Neither recurrences, nor major or minor complications have been reported to date.

Conclusion

Our THT is a feasible technique, easily reproducible, and effective in the repair of primary defects of the midline and RAD, which greatly reduces the operating times and hospitalization allowing a quick return to active life.

•

The THT procedure is a surgical technique for repair of the abdominal wall midline hernias and rectus abdominis diastasis.

•

The THT procedure combines the advantages of endoscopic single port surgery with those of a retromuscular prosthetic reconstruction.

•

The THT procedure strongly reduces costs and operative times if compared to lap/robotic surgery while allows to avoid the complication risks related to a large laparotomy.

The Retro-Rectus Prosthesis for Core Myofascial Restoration in Cosmetic Abdominoplasty

BACKGROUND

The retro-rectus placement of a prosthesis for reinforcement of a hernia repair is a powerful surgical maneuver and results in reduced hernia recurrence rates in the absence of ventral hernia. Fascial reinforcement theoretically should improve columnar support to the spine and enhance athletic activity. The purpose of this study was to demonstrate the long-term efficacy of the restoration of the cylindrical lumbar abdominal myofascial complex as an adjunct to cosmetic abdominoplasty.

OBJECTIVES

A retrospective evaluation of retro-rectus inlay prosthesis during cosmetic abdominoplasty was undertaken to subjectively assess aesthetic and functional benefits.

METHODS

Six patients with severe anterior fascial laxity presenting for abdominoplasty underwent prosthetic augmentation of the posterior rectus sheath. The prosthesis was measured and contoured to provide structural support to the rectus sheath and linea Alba and to restore normal anatomic features to these structures. All procedures were performed via a traditional low abdominal curvilinear incision for optimum cosmesis.

RESULTS

All 6 patients had long-term follow up, ranging from 13 to 40 months. All patients reported improved core strength and relief of back pain. All patients were pleased with the cosmetic results.

CONCLUSIONS

Retro-rectus prosthetic augmentation for cosmetic abdominoplasty is effective in restoring anatomic relationships and can be used to improve core strength and to enhance aesthetic objectives.

Single-Layer Plication for Repair of Diastasis Recti: The Most Rapid and Efficient Technique

Background

Plication of the anterior rectus sheath is the most commonly used technique for repair of diastasis recti, but is also a time-consuming procedure.

Objectives

The aim of this study was to compare the efficacy and time required to repair diastasis recti using different plication techniques.

Methods

Thirty women with similar abdominal deformities, who had had at least one pregnancy, were randomized into three groups to undergo abdominoplasty. Plication of the anterior rectus sheath was performed in two layers with 2-0 monofilament nylon suture (control group) or in a single layer with either a continuous 2-0 monofilament nylon suture (group I) or using a continuous barbed suture (group II). Operative time was recorded. All patients underwent ultrasound examination preoperatively and at 3 weeks and 6 months postoperatively to monitor for diastasis recurrence. The force required to bring the anterior rectus sheath to the midline was measured at the supraumbilical and infraumbilical levels.

Results

Patient age ranged from 26 to 50 years and body mass index from 20.56 to 29.17 kg/m2. A significant difference in mean operative time was found between the control and study groups (control group, 35 min:22 s; group I, 14 min:22 s; group II, 15 min:23 s; P < 0.001). Three patients in group II had recurrence of diastasis. There were no significant within- and between-group differences in tensile force on the aponeurosis.

Conclusions

Plication of the anterior rectus sheath in a single-layer with a continuous suture showed to be an efficient and rapid technique for repair of diastasis recti.

Endoscopic-Assisted Linea Alba Reconstruction plus Mesh Augmentation for Treatment of Umbilical and/or Epigastric Hernias and Rectus Abdominis Diastasis - Early Results

INTRODUCTION

Symptomatic umbilical and/or epigastric hernias are often seen concomitantly with rectus abdominis diastasis (RAD), and suture repair of such defects has a high recurrence rate. In the literature, there are reports of both endoscopic and open techniques for repair of symptomatic umbilical and/or epigastric hernias in association with RAD. This paper now reports on the early results of a hybrid technique used for reconstruction of the linea alba and mesh augmentation [endoscopic-assisted linea alba reconstruction plus mesh augmentation (ELAR plus)].

MATERIALS AND METHODS

Between 15 June 2015 and 31 January 2016, 40 patients with symptomatic umbilical and/or epigastric hernia and concomitant RAD underwent reconstruction of the linea alba using a hybrid technique involving a small umbilical incision and the use of video-endoscopic equipment. The patients comprised 29 men and 11 women with a mean age of 53.6 years and mean BMI of 32.6. The mean operating time was 120 min. The mesh had a mean longitudinal extension of 18.6 cm and transverse extension of 9.1 cm.

RESULTS

Thirty-day follow-up results are available for all patients. Thirty-seven out of 40 patients (92.5%) experienced no postoperative complication. Two cases of discrete impaired umbilical wound healing and one seroma were successfully managed with conservative treatment. On 30-day follow-up, 3 out of 40 patients (7.5%) complained of intermittent pain on exertion, and 2 out of 40 patients (5%) still took painkillers when required.

CONCLUSION

ELAR plus is a novel minimally invasive procedure for repair of symptomatic umbilical and/or epigastric hernias with concomitant RAD. Reconstruction of the linea alba via a minimally invasive access route is able to restore the normal anatomy of the abdominal wall.

Redefining abdominal anatomy: 10 key elements for restoring form in abdominoplasty

While traditional abdominoplasty methods can successfully achieve the objective of restoring a flat appearance, the results can be artificially board-like, lacking the subtle anatomical features of a three-dimensional abdomen, thus creating the potential for patient dissatisfaction. While often difficult to articulate, patient criticism is almost always distilled to the ubiquitous concern that the surgical abdomen lacks the natural features of an authentic, youthful abdomen. In an effort to provide a more anatomically accurate outcome and improve patient satisfaction, I have made a series of technical modifications to the abdominoplasty that I now perform. Ten key technical refinements, including a modified "Anatomy Defining" Progressive Tension Suture technique, were successively incorporated in 177 patients during the first 5 years of 2000-2014. All have been applied consistently in 961 abdominoplasty procedures during the subsequent 10 years, often accompanied by liposuction of adjacent lateral (non-abdominal) areas to ensure harmonious proportion. This series of refinements adds precision and detail by redefining the native anatomical nuances of the abdomen, an aesthetic objective that has been consistently achieved in BMI ranges between 20 and 35. Overall satisfaction with results was high (94%). The 10 elements described are safe, effective, and lasting.

Simultaneous prosthetic mesh abdominal wall reconstruction with abdominoplasty for ventral hernia and severe rectus diastasis repairs

BACKGROUND

Standard abdominoplasty rectus plication techniques may not suffice for severe cases of rectus diastasis. In the authors' experience, prosthetic mesh facilitates the repair of severe rectus diastasis with or without concomitant ventral hernias.

METHODS

A retrospective review of all abdominal wall surgery patients treated in the past 8 years by the senior author (G.A.D.) was performed. Patients with abdominoplasty and either rectus diastasis repair with mesh or a combined ventral hernia repair were analyzed.

RESULTS

Thirty-two patients, 29 women and three men, underwent mesh-reinforced midline repair with horizontal or vertical abdominoplasty. Patient characteristics included the following: mean age, 53 years; mean body mass index, 26 kg/m; average width of diastasis or hernia, 6.7 cm; and average surgery time, 151 minutes. There were no surgical-site infections and two surgical-site occurrences-two seromas treated with drainage in the office. After an average of 471 days' follow-up, none of the patients had recurrence of a bulge or a hernia.

CONCLUSIONS

For patients with significant rectus diastasis, with or without concomitant hernias, the described mesh repair is both safe and durable. Although this operation requires additional dissection and placement of prosthetic mesh in the retrorectus plane, it may be safely combined with standard horizontal or vertical abdominoplasty skin excision techniques to provide an aesthetically pleasing overall result.

Clinical application of a silk fibroin protein biologic scaffold for abdominal wall fascial reinforcement

Background:

Preclinical studies have demonstrated that macroporous silk fibroin protein scaffolds are capable of promoting physiologically durable supportive tissue, which favors application of these engineered tissues for clinical implantation. The safety and effectiveness of a long-lasting, transitory, 510(k)-cleared purified silk fibroin biologic scaffold (SBS) are investigated for soft-tissue support and repair of the abdominal wall.

Methods:

We conducted a multicenter retrospective review of all consecutive patients who underwent abdominal wall soft-tissue reinforcement with an SBS device between 2011 and 2013. Indications, comorbid conditions, surgical technique, complications, and outcomes were evaluated.

Results:

We reviewed the records of 172 consecutive patients who received an SBS for soft-tissue support. Of those, 77 patients underwent abdominal wall fascial repair, with a mean follow-up of 18.4 ± 7.5 months. Procedures using an SBS included reinforcement of an abdominal-based flap donor site (31.2%), ventral hernia repair (53.2%), and abdominoplasty (15.6%). The overall complication rate was 6.5%, consisting of 2 wound dehiscences, 1 with device exposure, 1 seroma, 1 infection with explantation, and a perioperative bulge requiring reoperation. There were no reports of hernia.

Conclusions:

Postoperative complication rates after 18 months were low, and most surgical complications were managed nonoperatively on an outpatient basis without mesh removal. To our knowledge, this is the only series to report on a long-lasting, transitory SBS for abdominal wall repair and reinforcement. Procedure-specific outcome studies are warranted to delineate optimal patient selection and define potential device characteristic advantages.

Is it possible to repair diastasis recti and shorten the aponeurosis at the same time?

BACKGROUND

Abdominal wall deformity secondary to pregnancy is multidirectional. Plication of the anterior rectus sheath is the most widely used technique for correction of this condition. However, it would be desirable to simultaneously perform the transverse and longitudinal repair of this deformity. The aim of this study was to assess changes in the length of the musculoaponeurotic layer after diastasis recti repair using triangular mattress sutures.

METHODS

Thirty-one women with Nahas' type III/A deformity were divided into two groups: the triangular mattress suture (TS) group and the continuous suture (CS) group. All patients underwent conventional abdominoplasty and diastasis recti repair with medial longitudinal plication performed between two metal clips. The two types of suture were used in both groups. In the TS group, after a CS was performed and removed, TSs were used and maintained in place. In the CS group, the order of suture placement was reversed. The distance between clips was measured before and immediately after suturing and at 3 weeks and 6 months postoperatively using plain abdominal radiographs. Statistical analysis was conducted using Friedman's analysis of variance and Wilcoxon's test.

RESULTS

The use of TSs significantly reduced the length of the aponeurosis compared with both the intraoperative situation without suture (P<0.001) and the use of CS (intraoperatively and 6 months after surgery; P<0.001).

CONCLUSION

The repair of diastasis recti using TSs resulted in vertical shortening of musculoaponeurotic layer immediately after the procedure and in the long term.

Use of SERI Surgical Scaffold for Soft-tissue Support in a Massive Weight Loss Patient

Supplemental Digital Content is available in the text.

Summary:

Patients with a history of massive weight loss have compromised and poor-quality skin and fascia. Various body contouring surgeries aim to improve appearance and shape of the trunk and restore fascial integrity. These patients may be at increased risk of recurrent fascial laxity or bulges after conventional techniques. Here, the author presents a case where a silk-based bioresorbable scaffold was used prophylactically in a massive weight loss patient undergoing a circumferential body lift.

Simple continuous suture versus continuous horizontal mattress suture for plication of abdominal fascia: which is better?

BACKGROUND

Abdominal fascia plication using a simple continuous suture can sometimes cause tears in the fascia. This problem can be circumvented when the continuous horizontal mattress suture is used. No data exist from comparing the two suturing techniques. The aim of this study was to examine which technique can potentially cause greater tissue damage. The time required to perform each type of suture was also recorded.

METHODS

Wound closure pads were plicated using the simple continuous and continuous horizontal mattress techniques performed by a single operator using Ethilon 2-0 nylon sutures. To verify their resilience, plastic bags were inflated beneath the pads to 30, 60, and 120 mmHg and tears were recorded. The time needed to perform the procedures was recorded using a stopwatch.

RESULTS

Mean time for the continuous vertical mattress suture was 87 s and for the simple continuous suture 116 s. Tears in the pad that was plicated with the simple continuous pattern were significantly longer than those in the pad plicated with the continuous horizontal mattress pattern (fissure mean length ± SD = 3.958 ± 0.157 vs. 2.736 ± 0.157, respectively, p < 0.001). This finding was true for each of the three measured pressures (fissure mean length for 30 mmHg was 3.40 ± 1.807 vs. 2.12 ± 1.709 cm; for 60 mmHg, 3.94 ± 2.90 vs. 2.90 ± 1.893 cm; and for 120 mmHg, 4.54 ± 1.924 vs. 3.19 ± 2.110 cm; p < 0.001).

CONCLUSIONS

Continuous horizontal mattress pattern sutures were found to be superior to simple continuous pattern sutures in the suggested model, in terms of suturing time and damage to the pad. Further research in human subjects is still required.

Lipoabdominoplasty: An exponential advantage for a consistently safe and aesthetic outcome

Background:

Extensive liposuction along with limited dissection of abdominal flaps is slowly emerging as a well proven advantageous method over standard abdominoplasty.

Materials and Methods:

A retrospective study analyzed 146 patients managed for the abdominal contour deformities from March 2004 to February 2010. A simple method to project the post operative outcome by rotation of a supine lateral photograph to upright posture in 46 patients prospectively has succeeded in projecting a predictable result. All patients were encouraged to practice chest physiotherapy in ‘tummy tuck’ position during the preoperative counseling. Aggressive liposuction of entire upper abdomen, a limited dissection in the midline, plication of diastasis of rectus whenever indicated, panniculectomy and neoumblicoplasty were done in all patients.

Results:

The patients had a mean age of 43, youngest being 29 and oldest 72 years. Majority were of normal weight (94%). Twelve were morbidly obese; 57 patients had undergone previous abdominal surgeries; 49 patients had associated hernias. Lipoabdominoplasty yielded a satisfactory result in 110 (94%) patients. The postoperative patient had a definitely less heavy harmonious abdomen with improved waistline. The complications were more with higher BMI, fat thickness of more than 7 cm and prolonged operating time when other procedures were combined.

Conclusions:

Extensive liposuction combined with limited dissection method applied to all abdominoplasty patients yielded consistently safe, reliable and predictable aesthetic results with less complications and faster recovery. The simple photographic manipulation has helped project the postoperative outcome reliably. The preoperative chest physiotherapy in tummytuck position helped prevent chest complications.

Rectus sheath plication in abdominoplasty: assessment of its longevity and a review of the literature

BACKGROUND

Correction of rectus diastasis during abdominoplasty is controversial. Few published studies have investigated the long-term value of plication. This prospective study aims to assess the long-term durability of plication of the rectus sheath in abdominoplasty using ultrasound.

METHODS

A total of 28 consecutive abdominoplasty patients underwent rectus plication by the senior author (FSF) since 2006, using a 0/0 looped nylon suture. Rectus diastasis was measured preoperatively and postoperatively at 3, 6 and 12 month's intervals using a standardised ultrasound (7.5 MHz) probe, by the single senior radiologist (GJD). Diastasis of the recti was assessed at three fixed points: at the umbilicus, 6 cm above and 6 cm below the umbilicus. Diastasis was categorised using the Beer classification.

RESULTS

All patients were female with a mean age of 36 years and average of body mass index (BMI) 26 kg m(-2). The majority of subjects had previous abdominal surgery including caesarean sections (82%, n = 23) and had at least one previous pregnancy (87%), with only two patients (8.7%) in the study being nulliparous. Correction of diastasis was maintained in all patients despite previous pregnancies and abdominal surgery. Postoperative follow-up time averaged 28 months (range 12-43 months). According to the Beer classification, there was no recurrence of rectus diastasis at the 12-month postoperative ultrasound measurements. A significant reduction in the mean distance between rectus muscles before surgery and 12 months postoperatively was noted. Previous surgery did not have a statistically significant affect on preoperative rectus distance.

CONCLUSIONS

Vertical rectus plication with a non-absorbable suture demonstrates long-term durable results without any suture-related complications. Patient factors such as extent of preoperative rectus diastases and previous abdominal surgery did not appear to have a significant effect on the durability of the corrected diastasis.

Repair of the midline fascial defect in abdominoplasty with long-acting barbed and smooth absorbable sutures

BACKGROUND

Traditionally, repair of the midline fascial defect has been performed with interrupted or running permanent sutures during abdominoplasty. Barbed suture devices, however, eliminate the need for knot tying and potentially are equally effective at maintaining the repair while allowing for faster deployment and elimination of a potential nidus for infection.

OBJECTIVE

The authors report their experience with long-acting absorbable barbed and smooth sutures.

METHODS

A retrospective chart review was conducted on 34 consecutive patients who underwent abdominoplasty, alone or in conjunction with other procedures, between August 2006 and December 2009. Seventeen patients had repair of the midline abdominal wall rectus diastasis performed with a smooth running absorbable polydioxanone suture, and 17 underwent repair with a barbed suture.

RESULTS

All 34 patients were women; their mean age was 43.6 years, and their mean body mass index was 23.0 kg/m(2). Sixty-eight percent of the patients elected to undergo concurrent procedures. Patients were followed for a mean of 34 months (27 months barbed; 42 months smooth). No cases of recurrent diastasis were observed. Complications included minor seroma (two cases in the barbed suture group, one in the smooth group) and infected hematoma (one in the barbed suture group).

CONCLUSIONS

Based on the data from this series of patients, long-acting absorbable barbed or smooth sutures appear to be equally effective in maintaining rectus diastasis repair. Barbed sutures therefore hold promise as a useful alternative to permanent sutures for the plication of the rectus fascia during abdominoplasty.

Analysis of the strength of the abdominal fascia in different sutures used in abdominoplasties

BACKGROUND

Protrusion of the abdominal wall secondary to abdominoplasty may occur in patients with weakness of the aponeurotic structures. The anterior layer of the rectus abdominis muscle consists of fibers that are transverse rather than vertical. Based on this anatomical feature, vertical sutures are suggested for the correction of diastasis recti, since they include a greater amount of fascial fibers and thus would be more resistant to tensile strength than horizontal ones.

METHODS

The anterior layers of the rectus abdominis muscles of 15 fresh cadavers were dissected. Two vertical lines were marked on each side of the linea alba, corresponding to the site where plication is usually performed in abdominoplasties. Three abdominal levels were evaluated: the supraumbilical, umbilical, and infraumbilical levels. A simple suture was placed in the vertical direction in one group and in the horizontal direction in the other group, at each of the three levels previously described. These sutures were connected to a dynamometer, which was pulled medially toward the linea alba until rupture of the aponeurosis occurred.

RESULTS

The mean strength required to rupture the aponeurotic structures in which the vertical sutures had been placed was greater than for the horizontal ones (p < 0.0001).

CONCLUSION

The vertical suture of the rectus abdominis sheaths was stronger than the horizontal suture because of the more transversal arrangement of its aponeurotic fibers. Thus, routine use of the vertical suture in plications of the aponeurosis of the rectus abdominis muscles is suggested.

A systematic review on the outcomes of correction of diastasis of the recti

PURPOSE

Diastasis or divarication of the rectus abdominus muscles describes the separation of the recti, usually as a result of the linea alba thinning and stretching. This review examines whether divaricated recti should be repaired and tries to establish if the inherent co-morbidity associated with surgical correction outweighs the benefits derived.

METHODS

EMBASE, MEDLINE and the Cochrane library were searched for ('divarication' OR 'diastasis') AND ('recti' OR 'rectus'). A standard data extraction form was used to extract data from each text. Due to the lack of randomised control trials, meta-analysis was not possible.

RESULTS

Seven studies report that patient satisfaction was high following surgery. The most common complication seen was the development of a seroma. Other common complications included haematomas, minor skin necrosis, wound infections, dehiscence, post-operative pain, nerve damage and recurrence, the rate of which may be as high as 40%.

CONCLUSIONS

Further studies are required to compare laparoscopic and open abdominoplasty techniques. Patients and physicians should be advised that correction is largely cosmetic, and although divarications may be unsightly they do not carry the same risks of actual herniation. Progressive techniques have resulted in risk reduction with no associated surgical mortality. However, the outcomes may be imperfect, with unsightly scarring, local sepsis and the possibility of recurrence.

The relationships between inter-recti distance measured by ultrasound imaging and abdominal muscle function in postpartum women: a 6-month follow-up study

STUDY DESIGN

A prospective longitudinal study.

BACKGROUND

Diastasis recti abdominis (DRA) is defined as an increase in the inter-recti distance (IRD), or width of the linea alba. It is a common occurrence in women postpartum. Little information exists on the short- and long-term recovery of IRD and the relationship between changes in IRD and the functional performance of the abdominal muscles.

OBJECTIVES

To investigate the natural recovery of IRD and abdominal muscle strength and endurance in women between 7 weeks and 6 months postpartum, and to examine the relationship between IRD and abdominal muscle function.

METHODS

Forty postpartum (25-37 years of age) and 20 age-matched, nulliparous females participated. IRD was measured at 4 locations (upper and lower margin of the umbilical ring, and 2.5 cm above and below the umbilical ring) with a 7.5-MHz linear ultrasound transducer. Trunk flexion and rotation strength and endurance were measured with manual muscle testing and curl-ups. Evaluation was conducted at 4 to 8 weeks and 6 to 8 months after childbirth in postpartum women, and only once for the nulliparous female controls.

RESULTS

During follow-up, the IRD at 2.5 cm above the umbilical ring and at the upper margin of the umbilical ring decreased (P = .013 and P = .002, respectively). The strength and static endurance of the abdominal muscles improved over time (P<.05). A negative correlation between IRD and abdominal muscle function at 7 weeks and 6 months postpartum was found (r = 0.34 to 0.51; P<.05, except for trunk flexion strength at 6 months postpartum [P = .064]). In addition, IRD changes between 7 weeks and 6 months postpartum were correlated with improvement in trunk flexion strength (Spearman rho = 0.38, P = .040). At 6 months after childbirth, postpartum women had greater mean ? SD IRDs at all 4 locations (from cranial to caudal: 1.80 ± 0.72, 2.13 ± 0.65, 1.81 ± 0.62, and 1.16 ± 0.58 cm) than those of nulliparous females (0.85 ± 0.26, 0.99 ± 0.31, 0.65 ± 0.23, and 0.43 ± 0.17 cm) (all P<.001). All abdominal strength and endurance measurements were less than those of nulliparous females (all P<.001).

CONCLUSIONS

The IRD and abdominal muscle function of postpartum women improved but had not returned to normal values at 6 months after childbirth. Future research is essential to explore the need for intervention and, if needed, the effectiveness of specific intervention to reduce the size of IRD in postpartum women.

Rectus diastasis corrected with absorbable suture: a long-term evaluation

BACKGROUND

Correction of rectus diastasis (RD) is performed during most abdominoplasties. This study aimed to evaluate the long-term result of RD correction when the plication of the anterior rectus sheath is performed with an absorbable suture.

METHODS

Abdominoplasty was performed for 12 women who presented with Nahas' type A musculoaponeurotic deformity. The RD was measured preoperatively with two computed tomography (CT) scan slices at two levels: 3 cm above and 2 cm below the umbilicus. The bony levels at which the slices were taken served as a reference for the postoperative CT scans. During the operation, the RD was measured with a ruler at the same levels as the preoperative CT scan slices. The force necessary to bring the medial edge of the rectus muscle to the midline was measured on both levels with a dynamometer. Plication of the anterior rectus sheath was performed using a double-layer 0-PDS (polydioxanone) suture. Postoperative CT scans were performed 3 weeks after the operation. A long-term follow-up CT scan was performed 32-48 months postoperatively for every patient.

RESULTS

The 3-week postoperative CT scan proved that the correction of RD was achieved by the procedure. Despite the fact that there were different abdominal wall resistances and that the average weight gain during this period was 4.5 kg, the long-term CT-scans showed no recurrence of RD for any patient of this series in either the superior or inferior abdomen.

CONCLUSION

Plication of the anterior rectus sheath with PDS suture to correct RD seems to be a long-lasting procedure.

Concepts on correction of the musculoaponeurotic layer in abdominoplasty

The musculoaponeurotic layer of the abdominal wall should be corrected during abdominoplasty according to the specific deformity that the patient presents with. In this article, the anatomic basis of deformities and defects of the abdominal wall is described. Different degrees of deformities secondary to pregnancy are described as well as congenital muscle malposition. These conditions should be treated in specific ways so that the most efficient correction can be achieved and no recurrence will occur. In cases of associated incisional hernias, the ''components separation'' technique can be considered for abdominal wall reconstruction and 2 alternative techniques of dissection of myoaponeurotic components are described for the correction of specific defects.

Neoumbilicoplasty Is a Useful Adjuvant Procedure in Abdominoplasty

Background

Neoumbilicoplasties are indicated in congenital conditions associated with umbilical agenesis, umbilical loss due to inflammatory destruction, excision of skin cancer involving the umbilical stump and in surgical procedures for herniorrhaphy, as well as in the rare condition of umbilical endometriosis.

Objective

Neoumbilicoplasty is an adjuvant procedure that may be necessary during abdominoplasty with wide myofascial plication, or repair of concomitant hernias of the abdominal wall. The present article justifies sacrificing the umbilicus followed by neoumbilicoplasty in patients with significant wide myofascial plication or concomitant hernias of the abdominal wall.

Methods

Seventeen patients underwent a combination of abdominoplasty and wide (greater than 10 cm) vertical plication of the myofascial complex and required neoumbilicoplasty. The male to female ratio was 1:16; mean age was 44 years, mean weight 94.1 kg and mean height 160.2 cm. Characteristic body morphology included gross trunk obesity with a prominent anterior abdominal wall. The female patients were multiparous. Sacrificing the umbilici followed by neoumbilicoplasty was required in patients with umbilical hernias and patients who had divarication of the rectus abdominis muscles with short umbilical stumps.

Results

Nine patients had concomitant ventral hernias (52.94%) and eight patients had divarication of the rectus abdominis muscles with short umbilical stumps (47.05%). The mean perioperative myofascial plication distance was 15.41 cm and the gap closure required three to five rows of sutures.

Conclusion

Neoumbilicoplasty is a useful adjuvant procedure during abdominoplasty with wide myofascial plication or repair of concomitant hernias of the abdominal wall.

The normal width of the linea alba in nulliparous women

The function of the linea alba is to maintain the abdominal muscles at a certain proximity to each other. In the case of long-lasting increased intra-abdominal pressure, the linea alba widens. Yet, as the existence of the linea a priori implicates a physiological distance between the two rectus muscles, the question arises as to what the normal width of the linea alba is. To evaluate the normal width of the linea alba, we examined 150 nulliparous women between 20 and 45 years of age with a body mass index < 30 kg m(-2) by ultrasound at three reference points: the origin at the xiphoid and 3 cm above and 2 cm below the umbilicus. The examination revealed a broad range of widths at the three reference points. The linea was widest at 3 cm above the umbilicus (-35 mm), followed by the reference point 2 cm below the umbilicus (-31 mm) and the origin at the xiphoid (-31 mm). The mean width was 7 +/- 5 mm at the xiphoid and 13 +/- 7 mm above and 8 +/- 6 mm below the umbilicus. For the definition of the normal width of the linea, the 10th and 90th percentiles were taken. The linea alba can be considered "normal" up to a width of 15 mm at the xiphoid, up to 22 mm at the reference point 3 cm above the umbilicus and up to 16 mm at the reference point 2 cm below the umbilicus in nulliparous women.
