A New Ultrasound-Guided, One-Point, Single Interfascial Plane Botulinum Toxin A Injection Technique for the Repair of Ventral Abdominal Wall Hernias Before Surgery: A Case Report.

Patients presenting with large ventral abdominal wall hernias require pretreatment with injection botulinum toxin A before surgery. Currently, multipoint and multilayered botulinum injection techniques are practiced. We are describing a new ultrasound-guided, 1-point, single interfascial plane botulinum toxin A injection technique for the closure of big hernial defects.

Repair of parastomal hernias with the intraperitoneal funnel meshes IPST-R and IPST.

The treatment of parastomal hernias (PSH) represents a major challenge in hernia surgery. Various techniques have been reported with different outcomes in terms of complication and recurrence rates. The aim of this study is to share our initial experience with the implantation of the DynaMesh-IPST-R and -IPST, intraperitoneal funnel meshes made of polyvinylidene fluoride (PVDF). This is a retrospective observational cohort study of patients treated for PSH between March 2019 and April 2023 using the chimney technique with the intraperitoneal funnel meshes IPST-R or IPST. The primary outcome was recurrence and the secondary outcomes were intraoperative and postoperative complications, the latter assessed using the Clavien-Dindo classification. A total of 21 consecutive patients were treated with intraperitoneal PVDF funnel meshes, 17 with IPST-R and 4 with IPST. There were no intraoperative complications. Overall, no complications occurred in 61.9% (n = 12) of the patients. Major postoperative complications (defined as Clavien-Dindo ≥ 3b) were noted in four cases (19.0%). During the mean follow-up period of 21.6 (range 4.8-37.5) months, one patient (4.8%) had a recurrence. In conclusion, for the treatment of parastomal hernias, the implantation of IPST-R or IPST mesh has proven to be efficient, easy to handle, and very safe. In particular, the low recurrence rate of 4.8%, which is in line with the current literature, is convincing. However, a larger number of patients would improve the validity of the results.

The use of botulinum toxin type a to prepare patients with large ventral hernias for laparoscopic hernioplasty: Our experience.

OBJECTIVE: Aim: To study the effectiveness of BTA in a total dose of 100 IU as the preparation for patients with primary and incisional ventral hernias (VH). PATIENTS AND METHODS: Materials and Methods: The prospective study included 59 patients with large VH (defect ³10 cm). All patients received 100 IU of BTA in abdominal wall muscles 4-5 weeks before surgery from June 2017 to December 2022. An average age of the patients was 59.13 ± 9.07 years, body mass index - 32.20 ± 4.95 kg/m2. RESULTS: Results: An average width of the hernia defect after BTA decreased by 4.5 ± 1.11 cm (p<0.001). An average length of the hernia defect after BTA also decreased, without clinical significance. A significant increase in the length of the abdominal wall and a decrease in its thickness were observed. The abdominal cavity volume after BTA increased by 4.04 ± 4.55% (p=0.008) and the hernial sac volume decreased by 21.43 ± 16.57% (p=0.005). All patients underwent surgery with hernia defect suturing and without component separation: laparoscopic IPOM hernioplasty - 50 (84.7%) patients, open IPOM hernia repair - 7 (11.9%) patients, open sublay hernioplasty - 2 (3.4%) patients. There was no recurrence of hernia during 12 months after surgery. CONCLUSION: Conclusions: The administration of 100 IU BTA allows to increase the length of the abdominal wall muscles and to perform laparoscopic IPOM hernioplasty for patients with large VH.

Development of an Enhanced Recovery After Surgery Program in Ventral Hernia.

BACKGROUND: Enhanced Recovery After Surgery (ERAS) programs have spread after initial success in colorectal surgery decreasing length of stay (LOS) and decreasing opioid consumption. Adoption of ERAS specifically for ventral hernia patients remains in evolution. This study presents the development and implementation of an ERAS pathway for ventral hernia. METHODS: A multidisciplinary team met weekly over 6 months to develop an ERAS pathway specific to ventral hernia patients. 75 process components and outcome measures were included, spanning multiple phases of care: Preoperative-Clinic, Preoperative Day of Surgery (DOS), Intraoperative, and Postoperative. Preoperative components included education and physiologic optimization. Pain control across phases of care focuses on nonopioid, multimodal analgesia. Postoperatively, the pathway emphasizes early diet advancement, early mobilization, and minimization of IV fluids. We compared compliance and outcome measures between a Pre Go-Live (PGL) period (9/1/2020-8/30/2021) and After Go-live (AGL) period (5/12/2022-5/19/2023). RESULTS: There were 125 patients in the PGL group and 169 patients in the AGL group. Overall, ERAS compliance increased from 73.9% to 82.9% after implementation. Length of stay decreased from an average of 2.27 days PGL to 1.92 days AGL. Finally, the average daily postoperative opioid usage decreased from 25.4 to 13.5 MME after the implementation. DISCUSSION: Enhanced Recovery After Surgery can be successfully applied to the care of hernia patients with improvements in LOS and decreased opioid consumption. Institutional support and multidisciplinary cooperation were key for the development of such a program.

Minimally Invasive Stapled Abdominal Wall Repair: A New Surgical Technique.

Background: Diastasis recti (DR) is a common condition, especially in women after pregnancy, often associated with concomitant hernia defects and defined as a rupture of the midline and a separation of the rectus muscle more than 2 cm. Symptoms related to this are low back pain, urinary incontinence and pelvic prolapse, as well as abdominal bulging and core instability. We analyzed clinical and functional outcomes after treatment of DR alone or associated with midline hernias in 219 patients who underwent a midline reconstruction using miSAR® technique (minimally invasive stapled abdominal wall reconstruction). Methods: Between April 2019 and April 2022, 219 patients were treated with miSAR®. All patients were requested to quantify preoperative and postoperative functional symptoms (urinary incontinence, low back pain, abdominal swelling, and respiratory distress). Results: Twenty-seven men and 192 women underwent the miSAR® technique. The mean body mass index was 23.9 kg/m2. We performed the miSAR® technique in patients affected by incisional midline hernia and umbilical hernia alone or associated with DR. Composite mesh was used in 91.8% of cases. The average operating time was 90 minutes. Seven percent of the patients had postoperative complications, including two retromuscular hematomas, two retromuscular seromas, and one postoperative bleeding event. Two patients were readmitted for bowel obstruction. After surgery, there was symptomatic improvement in urinary incontinence, low back pain, respiratory symptoms, and abdominal swelling; this improvement was confirmed at 6 months and at 1- and 2-year follow-up. At the 1-year follow-up, the overall recurrence rate was 2.83%. Conclusion: miSAR® is a feasible and effective technique and shows promising results in the treatment of DR and ventral hernia. Possible enhancements include use of preoperative Botox to treat defects larger than 6 cm. Multicentric analysis is needed to validate the technique, and longer follow-up is required to assess the recurrence rate.

Repair of Parastomal Hernias.

Parastomal hernias are an inevitable consequence of ostomy formation and their repairs remain a challenge to many surgeons. With multiple systems of classification and a multitude of techniques for hernia repair ranging from suture to mesh repair, the literature remains sparse with regards to the optimal method of repair. The authors describe the most commonly adopted techniques, discuss preventative measures, and review the current literature in the context of perioperative outcomes and hernia recurrence.

Perioperative and extended outcomes of patients undergoing parastomal hernia repair following cystectomy and ileal conduit.

PURPOSE: To report perioperative and long-term postoperative outcomes of cystectomy patients with ileal conduit (IC) urinary diversion undergoing parastomal hernia (PSH) repair. METHOD: We reviewed patients who underwent cystectomy and IC diversion between 2003 and 2022 in our center. Baseline variables, including surgical approach of PSH repair and repair technique, were captured. Multivariable Cox regressionanalysis was performed to test for the associations between different variables and PSH recurrence. RESULTS: Thirty-six patients with a median (IQR) age of 79 (73-82) years were included. The median time between cystectomy and PSH repair was 30 (14-49) months. Most PSH repairs (32/36, 89%) were performed electively, while 4 were due to small bowel obstruction. Hernia repairs were performed through open (n=25), robotic (10), and laparoscopic approaches (1). Surgical techniques included direct repair with mesh (20), direct repair without mesh (4), stoma relocation with mesh (5), and stomarelocation without mesh (7). The 90-day complication rate was 28%. In a median follow-up of 24 (7-47) months, 17 patients (47%) had a recurrence. The median time to recurrence was 9 (7-24) months. On multivariable analysis, 90-day complication following PSH repair was associated with an increased risk of recurrence. CONCLUSIONS: In this report of one of the largest series of PSH repair in the Urology literature, 47% of patients had a recurrence following hernia repair with a median follow-up time of 2 years. There was no significant difference in recurrence rates when comparing repair technique or the use of open or minimally invasive approaches.

Modified Chevrel Technique: A Lifesaver for Surgeons.

Background and Objectives: Ventral hernias (VH) pose significant challenges for surgeons due to the risk of recurrence, complexities in aligning abdominal muscles, and selecting the most suitable layer for mesh augmentation. This study aims to evaluate the effectiveness of utilizing the anterior rectus fascia as a turnover flap in conjunction with onlay mesh reinforcement, a procedure known as the modified Chevrel technique (MCT). Materials and Methods: We conducted a retrospective analysis of patients who were operated on using MCT for abdominal hernias between January 2013 and December 2019. Data were extracted from our hospital's electronic database. Recurrence rates, as well as the rates of surgical site occurrences (SSO), surgical site infections (SSI), and surgical site occurrences requiring procedural intervention (SSOPI), were analyzed based on patients' comorbidities and demographic characteristics. Results: The median follow-up period was 42.9 months (range: 14-96), and the recurrence rate was 4% (n = 3). Among the recurrent cases, three patients had chronic obstructive pulmonary disease, representing a statistically significant association (p = 0.02). Although all patients with recurrence were obese, this association did not reach statistical significance (p > 0.05). The mean hospitalization duration was 17.6 days (range: 6-29). SSO, SSI, and SSOPI rates were 39 (52%), 12 (16%), and 32 (42%), respectively. Conclusions: Managing VH remains a surgical challenge, emphasizing the importance of achieving effective abdominal closure for both functional and cosmetic outcomes. MCT presents a relatively simple approach compared to techniques like transversus abdominis release (TAR) and anterior component separation (ACS), with acceptable rates of SSO, SSOPI, SSI, and recurrence.

Bilateral rectus muscle turning-over for complicated and eventrated abdominal wall hernias: results of a novel method.

PURPOSE: We present a technique for covering large midline loss of abdominal wall using a novel method by autologous tissues. METHODS: Twenty-two patients (body mass index = 35,6 ± 6,9 kg/m2) were involved in the prospective cohort study. Acute and elective cases were included. The gap area was 450.1 ± 54 cm2. The average width of the midline gap was 16,3 ± 3,2 cm. The rectus muscles were mobilized from its posterior sheath. Both muscles were turned by180º medially, so that the complete abdominal wall gap could be covered without considerable tension. Changes in intra-abdominal pressure, quality of life and hernia recurrency were determined. RESULTS: There was no significant increase in the intra-abdominal pressure. Wound infection and seroma occurred in four cases. Bleeding occurred in one case. Pre- and post-operative quality of life index significantly improved (23 ± 13 vs. 47 ± 6; p = 0,0013). One recurrent hernia was registered. The procedure could be performed safely and yielded excellent results. The method was applied in acute cases. The intact anatomical structure of rectus muscles was essential. CONCLUSIONS: The midline reconstruction with bilateral turned-over rectus muscles provided low tension abdominal wall status, and it did not require synthetic mesh implantation.

Vulnerable populations and the emergency ventral hernia: A retrospective cohort study.

INTRODUCTION: Ventral hernias can be repaired electively; however, many circumstances require emergency repair. The association between sociodemographic status and rate of emergency repair are unclear and the Social Vulnerability Index may be a useful tool to better understanding this association. The purpose of this study was to investigate the association between Social Vulnerability Index and emergency ventral hernia repair. METHODS: This was a retrospective cohort study using the National Surgical Quality Improvement Program (2012-2018) data for patients at a level 1 trauma center. We included patients who had an open ventral hernia repair. Social Vulnerability Index was based on residential address at the time of surgery. We conducted univariate and bivariate statistics, including χ2 and Mann-Whitney U tests to compare high and low social vulnerability. RESULTS: Our sample had 1,017 patients. Patients who underwent emergency operations were older (P = .025) and had higher Social Vulnerability Index (P = .029). Patients in the high Social Vulnerability Index group were 1.5 times more likely to receive emergency surgery (P = .047). Emergency repair was also associated with increased frequency of nonhome discharge (9% vs 2%, P = .001) and higher mean work relative value unit (15.4 vs 11.9, P < .001). CONCLUSION: Patients requiring emergency ventral hernia repair have significantly higher Social Vulnerability Index than those undergoing elective repair. This vulnerable population also has increased cost associated with the repair and higher rates of nonhome discharge. This work provides a foundation for efforts to reach patients in high Social Vulnerability Index environments at an earlier stage to achieve earlier elective repair.

Perforated appendicitis within a spigelian hernia.

A woman in her 90s presented to the emergency department with new onset pain in a long standing right spigelian hernia. She was febrile and mildly hypotensive. CT scan demonstrated a hernia containing small and large bowel with significant fat stranding and thus proceeded to operative management via an open appendicectomy and suture repair of the hernia. There are few similar cases in the literature, with the predominance being suture repair, a roughly even split between open and laparoscopic approaches.

Effect of antiplatelet and anticoagulant therapy on bleeding complications following ventral hernia repair: An ACHQC analysis.

BACKGROUND: We investigate the effect of antiplatelet and anticoagulant medications on bleeding complications in patients undergoing ventral hernia repair. METHODS: The Abdominal Core Health Quality Collaborative registry was queried from 2013 to 2022 for patients who underwent ventral hernia repair, evaluating the association between antiplatelet or anticoagulant use and bleeding complications. RESULTS: 37,973 patients underwent ventral hernia repair: 11.5 â€‹% on antiplatelet therapy alone and 5.8 â€‹% on anticoagulation alone. Despite being held, an adjusted regression analysis showed that anticoagulation was associated with an increased risk for postoperative bleeding requiring transfusion (OR 2.4 [1.7-3.4], p â€‹< â€‹0.0001), reoperation for postoperative bleeding (OR 6.3 [3.9-10.0], p â€‹< â€‹0.0001), and readmission for bleeding complications (OR 4.9 [2.9-8.2], p â€‹< â€‹0.0001). Antiplatelet use was not a risk factor for any postoperative bleeding complication. CONCLUSION: Despite being held preoperatively, patients on anticoagulants are at an increased risk for postoperative hemorrhagic complications. Antiplatelet therapy does not pose the same risk.

The Effect of Bowel Anastomosis on Outcomes in Complex Abdominal Wall Reconstruction: A 10-Year Retrospective Cohort Study.

BACKGROUND: In patients who require complex abdominal wall reconstruction (CAWR), the need for a bowel anastomosis could impact procedure choice and outcome. In this retrospective cohort study, we examine the effect of bowel anastomosis on complications and hernia recurrence. METHODS: All patients who underwent CAWR between 2011 and 2021 by the senior author were reviewed in a retrospective cohort analysis. Patients were included if they met the above criteria. Patients were excluded if they did not undergo the above procedure or if they underwent a different procedure simultaneously. Univariate analysis was performed for patients who underwent bowel anastomosis, and multiple variable logistic regression analysis was performed with respect to overall complications. RESULTS: A total of 264 patients underwent CAWR over a 10-year interval. A total of 41 patients underwent bowel anastomosis (16%), and 223 patients (84%) underwent CAWR without bowel anastomosis. Mean patient age was 55.50 ± 11.55 years. Mean patient body mass index was 32.36 ± 7.31 kg/m 2 . Mean follow-up time was 10.20 months. There was a significant difference in hernia repair etiology, with higher rates of recurrent hernia repair among patients receiving bowel anastomosis (odds ratio, 2.98; 95% confidence interval, 1.49-5.95; P = 0.0018). Acellular dermal matrix was used more frequently in patients who required a bowel anastomosis (odds ratio, 3.74; 95% confidence interval, 1.75-8.00; P = 0.0018). Major and minor complications were also significantly higher in this cohort. Regression analysis for overall complications revealed the presence of bowel anastomosis, fascial repair technique, and follow-up time as independent predictors of overall complications. CONCLUSION: Bowel anastomosis performed at the time of CAWR significantly increased the rate of overall and major complications but did not predict hernia recurrence. Plastic surgeons should utilize this information in counseling patients and in deciding the most appropriate hernia repair technique.

Laparoscopic retromuscular hernia repair (LaHRR): a case-series of 17 patients treated with a novel technique for laparoscopic ventral hernia and diastasis repair.

INTRODUCTION: Many minimally invasive techniques have been developed over the years to treat primary ventral hernias and rectus abdominis diastasis, all of which have their advantages and disadvantages in terms of complications, reproducibility, and cost. We present a case-series of a novel approach that was safe and reproducible in a cohort of 17 patients. PATIENTS AND METHODS: All patients in the study underwent the novel procedure between October 2022 and July 2023. We collected data retrospectively, including patient general characteristics, surgical outcomes, and complications. Patient follow-up lasted 12 months to exclude recurrences. RESULTS: Seventeen patients underwent the procedure for primary uncomplicated ventral hernias and rectus diastasis. The median length of hospital stay was 2 days (IQR 2-3). In 4 out of 17 cases minor complications occurred within 30 days, of which 3 were class I and 1 was a class II complication according to the Clavien-Dindo classification. There were no recurrences. CONCLUSION: Although limited by a small cohort of patients and a non-comparative study design, our study presents encouraging results in regards to the safety of this technique. More studies with a larger study population are needed to evaluate the benefits and pitfalls of this new technique.[query names].

Specific Features of Diagnostic and Treatment Tactics in Patients with Crushed Abdominal Hernias Without Resection of a Hollow Organ.

The purpose of the work is to analyze the results of the use of optimized diagnostic and therapeutic tactics in patients with strangulated abdominal hernias without resection of the hollow organ. Materials and methods: The work is based on the analysis of the results of surgical treatment of 665 patients with strangulated abdominal hernias without resection of the hollow organ, who were divided into 2 groups depending on the features of the diagnostic and treatment tactics. Unlike the patients of group 1, the following diagnostic tactics were used in group 2: substantiated laparoscopic diagnosis of abdominal organs; mandatory biochemical assessment of hernia water; mandatory intraoperative instrumental assessment of the state of the strangulated organ; expansion of indications for the use of laparoscopic interventions and components of the comprehensive Fast track program; substantiated complex prevention of malignancy. The clinical diagnostic algorithm included laboratory, instrumental and biochemical research methods. Results: The use of priority diagnostic and therapeutic tactics in the patients of group 2 allowed to increase the number of laparoscopic hernioplasty by 49.34%, the number of allohernioplasty by 18.62%, among which the "Sublay" technique was preferred for strangulated ventral hernias. This was accompanied by a decrease in the pain syndrome on the VAS scale during the four days of observation, both during coughing and at rest, and amounted to only 2.21 ± 0.29 points on the fourth day when at rest. In addition, and after 12 months, the patients of group 2 observed a better recovery according to the SF-36 questionnaire, which amounted to 76.77±6.63 points for the assessment of the general state of health, 70.81±5.86 points for the assessment of physical functioning, 68.88±5.37 points for the assessment of role functioning due to physical condition, 68.03±5.92 points for the assessment of role functioning due to emotional state, and social activity was characterized by 72.82±5.52 points. Conclusions: 1. The proposed diagnostic and treatment tactics in the patients of group 2 with strangulated abdominal hernias without resection of a hollow organ, in contrast to patients in group 1, made it possible to increase the number of laparoscopic operations to 227 (66.37%) in contrast to 55 (17.03%) in the first group, which was accompanied by a decrease in pain syndrome on the VAS scale on the fourth day when coughing from 4.35 ± 0.38 points to 2.97 ± 0.43 points. 2. The expansion of indications for the use of laparoscopic operations in patients of group 2, in contrast to patients of group 1, led to a decrease in the postoperative complications by 10.48% and the postoperative mortality by 2.29% and was characterized by better postoperative rehabilitation according to the assessment of the patients' condition after 12 months according to the SF-36 questionnaire..

Application of botulinum toxin in the repair of a complex ventral hernia. / Aplicación de toxina botulínica en la reparación de una hernia ventral compleja.

INTRODUCTION: Preoperative application of botulinum toxin type A has demonstrated to be safe and effective in the closure of complex ventral hernias in adults. However, its use in pediatrics has been little documented. CASE REPORT: We present the case of a 22-month-old girl with a complex abdominal wall ventral hernia secondary to multiple neonatal laparotomies. In a first procedure, botulinum toxin was administered using an intramuscular approach at six sites of the muscle layers surrounding the defect, under general anesthesia and ultrasound control. 4 weeks later, an open hernia repair was conducted, without complications. DISCUSSION: Botulinum toxin at low doses could facilitate the surgical treatment of complex ventral incisional hernias in children. Even though it is important to adjust dosage and anatomical reference points according to hernia type and patient age and weight, further studies are required to optimize these variables.

INTRODUCCION: La aplicación preoperatoria de toxina botulínica A ha demostrado ser segura y efectiva en el cierre de hernias ventrales complejas en adultos. Sin embargo, se ha documentado poco su uso en pediatría. CASO CLINICO: Se presenta el caso de una niña de 22 meses con una hernia de pared abdominal ventral compleja secundaria a múltiples laparotomías neonatales. En una primera intervención se administró por vía intramuscular toxina botulínica en seis puntos de las capas musculares alrededor del defecto bajo anestesia general y control ecográfico. Cuatro semanas después, se realizó una reparación abierta de la hernia, sin complicaciones. COMENTARIOS: La toxina botulínica a dosis bajas podría facilitar el tratamiento quirúrgico de hernias incisionales ventrales complejas en niños. Es importante ajustar la dosis y los puntos de referencia anatómicos según el tipo de hernia, la edad y el peso del paciente, aunque se requieren más estudios para optimizar estas variables.

Spigelian hernias in the adult population: a systematic review of the literature.

PURPOSE: Spigelian Hernia (SH) is characterized by the protrusion of abdominal viscera or preperitoneal fat through a defect in the spigelian aponeurosis. The objective of this systematic review was to evaluate current literature on Spigelian Hernias in adult population and elucidate their characteristics and preferable management. METHODS: MEDLINE and Scopus bibliographical databases were systematically searched (last search: 31st January 2024) for studies concerning SHs. RESULTS: Two hundred and thirty-four articles met predefined inclusion criteria and concerned collectively 1,629 patients with SHs (58.7% females) with an age of 62.32 ± 17.71 (mean ± SD) years and a BMI of 28.56 ± 7.34 (mean ± SD) kg/m2. A minimally invasive approach was opted at 46.8% of cases, while a mesh was implemented at 67.9% of cases. Postoperative length of hospital stay was 2.8 ± 2.9 (mean ± SD) days. Following individual cases analysis, open surgery was preferable at emergency setting (OR: 2.45; 95% CI: 1.36-4.41; p-value: 0.003), and minimally invasive approaches were associated with shorter length of hospital stay [2 (1-9) vs. 5 (1-22) days; p-value: <0.001]. Overall, thirty-day postoperative morbidity and mortality rates reached 7.0% and 0.3% respectively. CONCLUSION: SH is a rare ventral hernia, and it concerns most frequently overweight women. Open surgical approach is preferred in emergency cases, while laparoscopic surgery is associated with shorter hospitalization. Further comparative studies are necessary to determine optimal surgical approach.

INTRA-ABDOMINAL PRESSURE MONITORING DURING LÁZARO DA SILVA'S PROCEDURE FOR VENTRAL HERNIA REPAIR: A CROSS-SECTIONAL STUDY.

BACKGROUND: Maintaining normal intra-abdominal pressure (IAP) levels must be one major outcome of any ventral hernia repair, avoiding hypertension or abdominal compartment syndrome. AIMS: To evaluate IAP during ventral hernia repair using Lázaro da Silva's procedure. METHODS: IAP measurements using intravesical pressure were performed during four crucial intraoperative moments. Twenty-eight patients submitted to incisional herniorrhaphy were analyzed. RESULTS: The IAP increased by 0.5 mmHg during the procedure, regardless of the type of prior laparotomy, sex, age, obesity, or hernia width. CONCLUSIONS: Despite the IAP increase observed, Lázaro da Silva's procedure did not result in intra-abdominal hypertension or abdominal compartment syndrome.
