Incisional Hernia

Incisional hernia is a type of abdominal wall defect that occurs at the site of a previous surgical incision.
It can develop after any type of abdominal surgery, such as appendectomy, hysterectomy, or colon resection.
Incisional hernias can cause pain, discomfort, and potentially serious complications if left untreated.
Effective management often requires surgical repair to restore the integrity of the abdominal wall and prevent further complications.
Understanding the optimal surgical protocols for incisional hernia repair is crucial for improving patient outcomes and reducing the risk of recurrence.
Pubcompare.ai's AI-driven tools can help researchers streamline their incisional hernia studies, locate the best protocols from literature, preprints, and patents, and enhance the reproducibility of their findings.

Chevrel and Rath [3 (link)] proposed a classification for incisional hernias in 2000. This classification is attractive, because it is simple, and the data required to reach the classification are readily obtained. Three parameters were utilised. Firstly, the localisation of the hernia of the abdominal wall: divided into median (M1–M4) and lateral (L1–L4) hernias. Secondly, the size of the hernia: it was postulated that the width of the hernia defect is the most important parameter (greater than hernia defect surface, length of the hernia or size of the hernia sac), which was divided into four groups (W1–W4). As a third parameter of this classification, subgroups were made for incisional hernias and recurrences: the number of previous hernia repairs was recorded as (R0, R1, R2, R3,…). Although apparently easy to use, this classification has not been commonly used in the literature.
In his book on hernia surgery, “Hernien”, Schumpelick described a classification that divided incisional hernias into five classes [2 ]. The size of the defect, the clinical aspect of the hernia in lying and standing position, the localisation of the incision and the number of previous repairs were used for this classification.
Korenkov et al. [4 (link)] reported on the results of an expert meeting on classification and surgical treatment of incisional hernia, but no detailed classification proposal resulted from this meeting.
Ammaturo and Bassi [6 (link)] suggested an additional parameter to the Chevrel classification. The ratio between the anterior abdominal wall surface and the wall defect surface predicts a strong abdominal wall tension when closing the defect, with possible abdominal compartment syndrome development, and thus might influence the choice of surgical technique.
Recently, Dietz et al. [5 (link)] proposed another alternative classification of incisional hernias in which variables like body type, hernia morphology and risk factors for recurrence were included and recommendations made for surgical repair based on the different types. It is based on a self-explanatory taxonomy and is intended to tailor the repair to the body type and risk factors of the individual patient.
The Swedish Abdominal Wall Hernia Registry presented their data collection sheet for incisional and ventral hernias at the EAES congress in Stockholm in June 2008, which forms the basis for a classification and includes many prognostic relevant variables. For this reason Agneta Montgomery was invited to the consensus meeting to present the method of classification used in Sweden.

When proposing a classification, it is important to determine the most suitable variables to include in the classification. However, it is important to keep a classification simple and practical to use. In Table 1 the potential variables are listed, as well as their use in previously proposed classifications. It is impossible to take all these variables into account for a practical classification, so a decision on inclusion or exclusion of various parameters was made.

An anatomic specimen embalmed by means of the Anubifix method was used. This embalming technique is based on a new prerinsing method combined with a normal 4% formaldehyde fixation solution. In contrast to conventional embalming methods, Anubifix embalming results in a very small decrease in flexibility and plasticity. Furthermore, this result is accomplished without impairing the quality and duration of conservation. Anubifix embalming results in a preserved range of motion of joints and flexibility of the abdominal wall combined with tissue tactility comparable to fresh-frozen tissues, this all in contrast to conventional embalming methods.
After the embalming phase, a midline laparotomy of 20 cm was performed. The specific aspects of the colorectal anatomy were dissected and marked [aorta and iliac arteries (dark red), superior mesenteric artery/vein and its branches (red/blue), inferior mesenteric artery/vein and its branches (red/blue), gonadal arteries (purple), and ureters (yellow)]. Coloring of the vessels and ureters was performed circumferentially with a specially developed formaldehyde-proof paint (FPP). After dissection and coloring, the abdominal muscle wall was separated from the overlying fat and skin and closed with running sutures. A rectangular sheet of synthetic butyl rubber measuring 26 × 6 cm with a circular hole at the level of the umbilicus was sutured on top of the sutured muscle wall, analogous to an onlay mesh for incisional hernia, after which the skin was closed with running sutures. The use of a butyl rubber sheet results in an airtight closure of the abdominal wall permitting the creation of a pneumoperitoneum despite the prior abdominal opening. A 10-mm trocar was placed at the umbilicus through which a 30º scope was placed. A standard set of laparoscopic instruments was used. Four 5-mm trocars were placed in the right and left upper quadrants. Pneumoperitoneum was achieved with a continuous flow of CO2, with the pressure set between 12 and 15 mmHg, i.e., comparable to the in vivo situation.

The first decision to take was whether the classification would involve primary ventral hernias and incisional ventral hernias in one classification or if two separate classifications were preferable. A consensus was reached on the decision to separate the two entities, since in the authors’ opinion primary ventral hernias have a different aetiopathology compared with incisional abdominal wall hernias resulting from failure of a previous incision. The group reached agreement on separating non-incisional hernias, “primary abdominal wall hernias” (also known as “ventral”). and the other “incisional abdominal wall hernias”. A recurrent hernia after a primary abdominal wall hernia treatment will then fall into the incisional hernia group. To avoid confusion, the word “primary incisional hernia” should not be used.
There was a consensus to exclude “parastomal hernias” from this classification. Although they are by definition incisional hernias, they make up a distinct group, with specific properties and treatment options.

SPSS 28 was used to manage and analyze data (IBM, Armonk, New York, United States). Quantitative data normality was determined using Kolmogorov–Smirnov, Shapiro–Wilk, and direct data visualization. Categorical data are presented with numbers and percentages. Quantitative and qualitative data were compared using the Chi-square and independent t-test, respectively. Multivariate logistic regression analysis determined the odds ratio and 95% confidence interval for incisional hernia predictors. All tests were two-sample. P-value < 0.05 was considered significant. The selection of variables in the model was made based on knowledge and clinical experience that produces a better model. We considered variables that are anticipated to cause an incisional hernia. Each variable was evaluated, controlling for the effect of possible and well-known confounders using ENTER method. Each variable was separately evaluated as we had a low incidence of incisional hernia (18 patients), not allowing to include many predictors in one model and may lead to a non-robust estimate. Additionally, to avoid multicollinearity, a very common, well-known problem in the case of multiple predictors. Multicollinearity can destroy a regression model and reverse the effect of predictors on the outcome.

Incisional Hernia Patients
Data will be collected at the baseline (before surgery), during the hospital stay, at 30 days, and at 6, 12, and 36 months after surgery (Table 1). The primary outcome of this study is the incidence of incisional hernias, including both symptomatic and radiologic hernias, at 12 months after surgery. Incisional hernia is assessed by interviewing patients regarding subjective symptoms, performing a physical examination of the abdomen, and reviewing abdominal-pelvic computed tomography (CT) scans. An incisional hernia is defined as either a symptomatic hernia during the interview or a radiologic hernia when it is diagnosed on both an abdominal-pelvic CT scan and a physical examination in cases where subjective symptoms do not exist. The secondary outcomes are the length of hospital stay, estimated blood loss, pain numerical rating scale (0: no; 10: worst pain imaginable) score on postoperative days 1, 2, and 3; reoperation, open conversion, 30-day postoperative complications, (as classified by the Clavien–Dindo classification) [9 (link)], surgical site infection (as classified by the Center for Disease Control and Prevention criteria [10 (link)] and ASEPSIS score [11 (link)]), 30-day mortality, the incidence of repair of incisional hernias, pathologic result of colon cancer (pathologic stage, histologic type, differentiation, number of harvested and metastatic regional lymph nodes, lymphovascular, venous, and perineural invasion, and distant metastasis), and patient-reported outcomes (short form-12 health survey questionnaire before surgery, and at 12 months after surgery and Body Image Questionnaire at 12 months after surgery) [12 (link), 13 (link)]. The incidence of incisional hernia at 36 months after surgery is another secondary outcome that will be separately analysed and reported after the last patient enrolled completes the follow-up.

A small incision will be made by extending the periumbilical port for the camera scope in both groups. The size of the small incision will be determined based on the size of the tumour and the physical habits of the patient. The fascial closure methods are standardised as continuous closure using Stratafix (SF Symmetric PDS Plus®) with a 4:1 ratio (4-to-1 suture to wound length ratio) and bites of < 1 cm. The methods for closure of the subcutaneous fat and skin (skin stapler or 3–0 nylon vertical mattress) depend on the surgeon’s discretion. Patients randomly assigned to the midline group will undergo an incision along the midline skin, subcutaneous fat, and linea alba.
In the non-muscle-cutting periumbilical transverse group, the method of small incision is the same as in a previous report (Fig. 2) [6 (link)]. Briefly, the skin incision of the 11-mm periumbilical port will be extended transversely. Using monopolar electrocautery and crossing linea alba, the anterior and posterior rectus sheaths are transversely incised. With lateral traction of the rectus abdominis muscle with an army retractor, the posterior rectus sheath can be seen (Supplemental Video 1). The transversalis fascia and parietal peritoneum are further incised transversely. Continuous fascia closure will be separately performed for the anterior and posterior rectus sheaths. Implementing vertical or transverse incisions will not require alteration to usual care pathways (including the use of any medication), and these will continue for both trial arms.

Data analysis will be performed using primary analysis (ITT), followed by secondary analysis (as-treated principles). The ITT set includes all patients who were randomised regardless of whether they received each incision, and the “per-protocol” analysis set includes patients who were treated according to protocol, excluding major protocol violations. Given our expectation, very few patients will crossover between incision types. All baseline and outcome data will be presented using frequencies with proportions for categorical variables and means with standard deviations for continuous data (or medians with interquartile ranges, whichever is more appropriate). The patients will be compared based on their baseline characteristics, including age, sex, body mass index, American Society of Anaesthesiologists classification, preoperative treatment (none, radiotherapy, or chemotherapy), comorbidities, medications, history of previous abdominal surgery, location of the tumour (right or left), and baseline short form-12 health survey questionnaire to determine the balance between the two groups. The primary outcome (the incidence of incisional hernia) will be analysed using the chi-square test. The secondary outcomes will be analysed using the chi-square test for categorical variables (i.e. type of surgery, resection, and anastomosis, incidence of 30-day postoperative complications, histologic type, and depth of the tumour), and Student’s t-test or Mann–Whitney U test for quantitative variables (i.e. operative time, length of hospital stay, blood loss, postoperative pain scores, size of the tumour, and the number of lymph nodes) as appropriate. In accordance with symptoms, each incision type will be evaluated during follow-up after surgery. However, it is not expected that there will be missing data relating to the primary outcomes. For other possible missing data, multiple imputations will be made, based on the assumption that the data are missing at random.
Subgroup analyses will be conducted for each randomisation stratum. The results will be evaluated at a significance threshold of p < 0.05 (two-sided). All of the statistical analyses will be performed using R statistical software, version 3.4.3 (R Foundation for Statistical Computing).

This study aimed to test the superiority of the non-muscle-cutting periumbilical transverse incision over the midline incision, and the sample size was estimated based on the primary outcome (the incidence of incisional hernia at 12 months after surgery). Our previous retrospective study showed that the incidence of incisional hernias was 2.4% and 14.9% in non-muscle-cutting periumbilical transverse and midline incisions, respectively [6 (link)]. For this study, a conservative estimate rounded these incidences up to 2.5% and 15%, respectively. The sample size calculations were conducted in R using the pwr (pwr.2p.test); the required sample size for a superiority trial was determined to be 158 patients using power analysis (power = 85%, ɑ = 0.05, two-sided), and the dropout rate was anticipated at 10%. Finally, a total of 176 patients are required for randomisation.

More about "Incisional Hernia"

Incisional hernias, also known as ventral hernias, are a common complication following abdominal surgery.
They occur when the surgical incision fails to heal properly, allowing internal organs or tissue to protrude through the weakened abdominal wall.
These types of hernias can develop after any type of abdominal procedure, including appendectomy, hysterectomy, or colon resection.
Incisional hernias can cause a range of symptoms, including pain, discomfort, and potentially serious complications if left untreated.
Effective management often requires surgical repair using techniques like open incisional hernia repair or laparoscopic incisional hernia repair to restore the integrity of the abdominal wall and prevent further complications.
Understanding the optimal surgical protocols for incisional hernia repair is crucial for improving patient outcomes and reducing the risk of recurrence.
Researchers can utilize AI-driven tools like those offered by PubCompare.ai to streamline their incisional hernia studies, locate the best protocols from literature, preprints, and patents, and enhance the reproducibility of their findings.
When it comes to the surgical repair of incisional hernias, various suturing materials and techniques may be employed, such as Polysorb, PDS Plus 2-0, or other absorbable or non-absorbable sutures.
Statistical software like SPSS, Statistica, SAS, or STATA can also be used to analyze data and optimize surgical outcomes.
By incorporating the latest research, innovative technologies, and proven surgical methods, healthcare providers can deliver more effective and personalized treatment for patients with incisional hernias, ultimately improving their quality of life and reducing the risk of recurrence.
