Preoperative Progressive Pneumoperitoneum Revisited

Preoperative progressive pneumoperitoneum: insights on implementation in an ambulatory care setting. How I do it?

INTRODUCTION

Incisional hernias with loss of domain (IHLD) are challenging to treat. Preoperative techniques like botulinum toxin injection (BTA) and preoperative progressive pneumoperitoneum (PPP) are highly effective, potentially preventing the need for perioperative component separation in the vast majority of cases. PPP involves preoperative introduction of gas into the abdominal cavity to increase the abdominal wall volume, aiding diaphragmatic prehabilitation and hernia reintegration. This study aimed at explaining our technique in performing PPP in ambulatory setting.

DESCRIPTION OF THE TECHNIQUE

The first insufflation and BTA injection occur during a 3-day hospitalization. Subsequently, patients are managed on an ambulatory basis with three sessions per week for at least three weeks. Each hospital visit lasts about 1 to 2 h. Patients can remain at home or in a residential center of our hospital. No preventive anticoagulation nor prophylactic antibiotics are needed.

DISCUSSION

Performing PPP in outpatient care does not compromise its efficacy. Instead, it allows for longer preparation, potentially improving efficacy. Patients maintain daily activities, possibly yielding better results than traditional physiotherapy. It reduces hospital stay costs and nosocomial infection risks. Each ambulatory hospitalization offers better patient attention.

CONCLUSIONS

PPP is a valuable preoperative technique for IHLD repair, particularly in combination with botulinum toxin, offering potential benefits for selected patients. Performing it in outpatient care may enhance patient satisfaction and offers several advantages.

Primary ventral and incisional hernias: comprehensive review

BACKGROUND

Primary ventral and incisional hernias are frequent conditions that impact the quality of life of patients. Surgical techniques for ventral hernia repair are constantly evolving and abdominal wall surgery has turned into a highly specialized field.

METHODS

This is a narrative review of the most recent and relevant literature on the treatment of primary ventral and incisional hernias performed by eight experts in ventral hernia surgery from across the world and includes review of classification systems, preoperative measures, descriptions of surgical techniques, and postoperative complications.

RESULTS

Repairs of primary ventral and incisional hernias range from simple open procedures in healthy patients with small defects to complex procedures when patients are co-morbid and have large defects. Optimizing patient-related risk factors before surgery is important to decrease complication rates. Surgical repair techniques from open repairs to minimally invasive procedures are described in detail in the review. Minimally invasive techniques are technically more demanding and take longer, but decrease the risk of surgical-site infections and shorten the duration of hospital stay.

CONCLUSION

Treatment of ventral hernias aims to improve the quality of life of patients. The risks and benefits of procedures should be weighed against patients' complaints and co-morbidities. Optimizing patient-related risk factors before surgery is important.

Complications related to the prehabilitation with preoperative pneumoperitoneum in loss of domain hernias: our experience in 180 consecutive cases

OBJECTIVE

Progressive pneumoperitoneum (PPP) is useful tool in the preparation of patients with loss of domain hernias (LODH). The purpose of this observational retrospective study was to report our experience in the management of complications associated with the PPP procedure after treating 180 patients with LODH and to report preventive measures to avoid them.

METHODS

Of the 971 patients with a ventral incisional hernia operated on between June 2012 and July 2022, 180 consecutive patients with LODH were retrospectively analysed. Diameters of abdominal cavity, and volumes of incisional hernia and abdominal cavity were calculated from CT scan, based on the modified index of Tanaka. Complications related to the PPP procedure (catheter placement and following insufflations of air) were recorded by Clavien-Dindo classification.

RESULTS

Complications associated to PPP were 26.6%. No complications occurred during the administration of botulinum toxin (BT). Eighteen patients (10% of 180 patients) developed subcutaneous emphysema during the last days of the insufflations; there were 2 accidental perforations of the small bowel and four punctures with liver and splenic hematomas, detected during catheter placement; a laparotomy, however, was not needed because it was solved with conservative treatment. We diagnosed it as a peritoneum-cutaneous fistula due to the cutaneous atrophy secondary to chronic eventration.

CONCLUSION

PPP is a safe technique well tolerated by patients, although at the cost of some specific complications. Hernia surgeons must understand these complications to prevent them and to inform the LODH patient about their existence.

Intra-abdominal hypertension and compartment syndrome after complex hernia repair

PURPOSE

Abdominal compartment syndrome (ACS) is a well-known concept after trauma surgery or after major abdominal surgery in critically ill patients. However, ACS as a complication after complex hernia repair is considered rare and supporting literature is scarce. As complexity in abdominal wall repair increases, with the introduction of new tools and advanced techniques, ACS incidence might rise and should be carefully considered when dealing with complex abdominal wall hernias. In this narrative review, a summary of the current literature will highlight several key features in the diagnosis and management of ACS in complex abdominal wall repair and discuss several treatment options during the different steps of complex AWR.

METHODS

We performed a literature search across PubMed using the search terms: "Abdominal Compartment syndrome," "Intra-abdominal pressure," "Complex abdominal hernia," and "Ventral hernia." Articles corresponding to these search terms were individually reviewed by primary author and selected on relevance.

CONCLUSION

Intra-abdominal hypertension (IAH) and ACS require imperative attention and should be carefully considered when dealing with complex abdominal wall hernias, even without significant loss of domain. Development of a true abdominal compartment syndrome is relatively rare, but is a devastating complication and should be prevented at all cost. Current evidence on surgical treatment of ACS after hernia repair is scarce, but conservative management might be an option in the early phase and low grades of IAH. However, life-saving treatment by relaparotomy and open abdomen management should be initiated when ACS starts setting in.

The Impact of Botulinum Toxin A Application on Reducing the Necessity for "Component Separation Techniques" in Giant Incisional Hernias: A Dual-Center, Polish-Ukrainian, Retrospective Cohort Study

<b>Introduction:</b> Incisional hernias are prevalent complications, with significant recurrence rates and associated surgical wound complications. Giant hernias, classified by the European Hernia Society (EHS) as exceeding 10 cm (width dimension), pose a challenge due to the "loss of domain" effect. Component separation techniques (CST), including anterior component separation (ACS) and transversus abdominis release (TAR), are established interventions but have drawbacks related to the irreversible alteration of abdominal wall anatomy and associated risks. An alternative approach involves the preoperative application of Botulinum Toxin A (BTA) to reduce lateral abdominal muscle tension, facilitating hernial defect closure.<b>Aim:</b> The aim was to assess the impact of BTA on reducing the necessity for CST, the occurrence of surgical site complications,and the need for further interventions.<b>Materials and methods:</b> A retrospective cohort study was conducted across two reference centers specializing in hernia treatment in Poland and Ukraine. The study compared outcomes between patients undergoing elective abdominal wall reconstruction surgery for giant hernias, specifically looking at the requirement for CST following preoperative BTA application. Patients were divided into two groups - those who received BTA injections 3-4 weeks prior to surgery (BOTOX group) and those who did not (NON-BOTOX group).<b>Results:</b> The study found that in the BOTOX group, a significantly lower proportion of patients required CST compared to the NON-BOTOX group (46 <i>vs</i> 84%, P-value = 0.000124). Additionally, the BOTOX group experienced fewer postoperative complications, suggesting a beneficial effect of BTA in simplifying surgical procedures and enhancing patient outcomes.<b>Conclusions:</b> The findings support the use of preoperative BTA injections as a valuable adjunct in the management of giant abdominal hernias. This approach not only facilitates fascial closure without the need for extensive CST but also potentially reduces perioperative trauma and postoperative complications. Preoperative BTA injections significantly reduce the need for CST in giant incisional abdominal hernia repairs, offering a less invasive and more effective approach to fascial closure. The most important role of BTA is "downstaging" the hernia before surgery. This study highlights the importance of considering BTA injections in preoperative protocols, advocating for broader acceptance and reimbursement to improve surgical outcomes and patient care in hernia surgery.

Botulinum Toxin and Progressive Pneumoperitoneum in Loss of Domain Ventral Hernias: A Systematic Review

Introduction: Preoperative progressive pneumoperitoneum (PPP) and botulinum toxin A (BTX) have been used together in the preoperative preparation of patients with loss of domain hernias. This study aims to evaluate the efficacy and safety of the combined use of PPP and BTX. Methods: A systematic electronic search was performed according to the PRISMA criteria. A literature search of scientific articles was conducted up to December 2023. Articles were chosen based on the reference to BTX and PPP in loss of domain ventral hernias with a defect width greater than 10 cm before surgery. The GRADE methodology and the modified Newcastle-Ottawa scale were used to assess the quality of the studies. Results: The research yielded seven articles, with 217 patients analysed in total. BTX was performed 29.5 ± 1.7 days before surgery and PPP was inflated 14.8 ± 5.8 days before surgery. PPP complications were reported in 25.6% of patients, The average reduction of the volume of hernia (VH)/volume of the abdominal cavity (VAC) ratio was 7.6% (range 0.9%-15%). Only 40 patients (18.4%) required a PCS or TAR to repair the loss of domain hernias. The SSI and SSO rates were 17.5% and 26.2%, respectively. No differences in SSI and SSO rates were found between the different repair techniques. The recurrence rate was 5.9% (13/217). Recurrence was significantly higher in patients who underwent IPOM repair than other techniques (p < 0.001). Conclusion: BTX and PPP may be useful tools for the management of loss of domain hernias presenting lower SSI and SSO. The combination of BTX and PPP reduces the use of more invasive repair techniques.

Effective Management of Giant Ventral Hernias: A Comprehensive Approach Combining Preoperative Botulinum Toxin Application, Modified Ramírez's Component Separation, and Rives-Stoppa Hernioplasty

Introduction  Giant ventral hernias are a surgical challenge due to their size and the need for a specialized approach during repair. Over the decades, abdominal wall surgery has evolved into a sophisticated field with a wide range of techniques aimed at improving patient outcomes. However, there is no universally accepted method suitable for repairing all giant ventral hernias. Surgeons must rely on a combination of techniques, choosing the approach that best matches their expertise, available resources, and the individual patient's specific needs. This article explores the effective use of a combination of techniques, including preoperative botulinum toxin application, modified Ramírez's component separation, and Rives-Stoppa hernioplasty, yielding excellent results and minimizing recurrences. Objective  This study aims to provide a comprehensive literature review of giant ventral hernias. Additionally, we aim to share our experience in managing and repairing giant ventral hernias using a multi-modal approach, combining various surgical techniques with a focus on patient safety, reduced recurrence rates, and improved quality of life. Methods Between October 1, 2019, and October 1, 2021, six patients with giant ventral hernias were enrolled at our department of surgery. They received preoperative botulinum toxin A (BT) application, underwent corrective surgery involving modified component separation following the Ramírez method, and received Rives-Stoppa hernioplasty. Follow-up was conducted for at least six months. Results Six patients were included in the study: three women and three men. They had an average age of 53.6 years and an average body mass index of 31.8 kg/m2. The most common location of the hernia defect was supra and infraumbilical, among 66% of cases. The primary adverse effect associated with BT application was abdominal distension, reported in 33% of patients. No postoperative complications, such as abscesses or seromas, were observed. After the surgical procedure, the average hospital stay was 2.6 days, and no recurrences were noted within six months post-surgery. Conclusion  The proposed method, which involves a combination of techniques, has demonstrated promising results based on our experience. However, to solidify these findings and better understand the full scope of this approach, further comprehensive statistical studies involving larger populations are essential. These studies will not only validate our results but also provide valuable insights for optimizing the management of giant ventral hernias.

Preoperative Optimization for Abdominal Wall Reconstruction

Patients requiring abdominal wall reconstruction may have medical comorbidities and/or complex defects. Comorbidities such as smoking, diabetes, obesity, cirrhosis, and frailty have been associated with an increased risk of postoperative complications. Prehabilitation strategies are variably associated with improved outcomes. Large hernia defects and loss of domain may present challenges in achieving fascial closure, an important part of restoring abdominal wall function. Prehabilitation of the abdominal wall can be achieved with the use of botulinum toxin A, and preoperative progressive pneumoperitoneum.
