Background The spread distance of local anesthetic (LA) in the rectus sheath block (RSB) should cover the planned surgical incision. However, there is limited data regarding the spread distance that can be covered by a certain volume in children. In this study, we aimed to investigate the spread distance of a particular volume of LA from a single injection point. Methodology This study included children aged 0-8 years (n = 41) who underwent umbilical or epigastric hernia repair, laparoscopic surgery, and surgeries via small midline incisions. The spread distances, which were measured via ultrasound guidance immediately after the block to ensure coverage of the entire planned surgical incision, were obtained from prospectively collected data about RSB. The spread distances in the craniocaudal direction on the right and left sides were compared and assessed for correlations with age, weight, LA volume, and sex. The need for a supplemental dose of LA in case of an incision exceeding the spread distance was also obtained from the records. Results The spread distances in the cranial and caudal directions from the injection point were 3.28 ± 1.04 cm and 3.74 ± 1.35 cm on the right (p = 0.066) and 3.44 ± 1.02 cm and 3.44 ± 1.33 cm on the left (p > 0.999), respectively. The total spread distances in the craniocaudal direction on the right and left were 5.55 ± 0.95 cm and 5.72 ± 1.28 cm in patients aged 0-2 years and 7.25 ± 1.92 cm and 7.39 ± 1.81 cm in patients aged at 2-8 years, respectively. The increase in the spread distance correlated with age, weight, and LA volume. None of the patients required a supplemental dose of LA, as the single-point injections covered the planned surgical incisions in all patients. Conclusions Similar spread distances in the cranial and caudal directions from a single injection point can be obtained with 0.5 mL/kg of the LA in 0-8-year-old children. The total spread distance in the craniocaudal direction was approximately 5 cm and 7 cm in children aged 0-2 years and 2-8 years, respectively.

The objective of this study is to assess the effectiveness and safety of onlay mesh closure of emergency midline laparotomy to prevent incisional hernia.
This is a prospective randomized double-blind study and was carried out in the General Surgery Clinic, Konya City Hospital, from August 1, 2020 to August, 1, 2021. The study included 108 patients who were randomly grouped in 2 groups: patients with conventional abdominal closure and closure using additional onlay mesh (1:1). The follow-up period was for a year. The primary outcome was the incidence of incisional hernia and secondary outcomes were clinical data like complications, hospital length of stay, re-operations.
It was observed that incisional hernia was present in 14 patients (27.4%) in conventional abdominal closure group and was in 2 patients using mesh (4%), (p = 0.001). Clavien-Dindo 3B complications were in rise in conventional closure group (p = 0.02). Of all complications, burst abdomen was significantly more common in conventional closure group (p = 0.04). The rate of surgically treated complications were higher in conventional closure group (p = 0.02). Clavien-Dindo 3A complications were more common in patients with contaminated wound in mesh group (p = 0.02).
The use of mesh while closing the abdomen in emergency midline laparotomy reduces the risk of incisional hernia. Thus, to lower the risks of incisional hernia and its complications, prophylactic mesh can be used in high-risk patients.

Abdominal hernia (AH) is one of the most common clinical diseases. A large number of observational studies have found that obesity is an important risk factor for AH. However, the causal relationship between obesity and AH cannot be determined because of the clinical studies on AH induced by obesity are relatively few and only have some small- or medium-scale observational studies. Observational studies have so many confounding factors and reverse causality due to their shortcomings. From an evidence-based medicine perspective, they are not sufficiently convincing. Therefore, there is still a lack of high-quality, evidence-based medical evidence supporting a causal relationship between obesity and AH. A causal relationship between obesity and AH is also almost impossible to confirm by randomized controlled trials (RCTs). Our study based on Mendelian randomization (MR) may provide a higher level of evidence-based medical support for the relationship between obesity and AH. Body mass index (BMI) is the most common measure used for defining obesity. Finally, we employed two-sample Mendelian randomization (TSMR) to explore the causal relationship between BMI and AH.
AH-related single nucleotide polymorphisms (SNPs) data were obtained from the FinnGen Biobank (FB), and BMI-related single nucleotide polymorphisms (SNPs) data were obtained from the UK Biobank (UKB). Genetic loci are used as instrumental variables (IVs), methods such as inverse variance weighted (IVW) were used for two-sample Mendelian randomization analysis, and the odds ratio (OR) value was used to evaluate the causal relationship between BMI and AH.
The results of the horizontal pleiotropy test were calculated by Egger-intercept method: p = 0.34 > 0.05. The Cochran Q test of MR-Egger method and IVW method showed heterogeneity P = 0.03 < 0.05, so the IVW random effect model was used as the gold standard. We found a genetically determined 1-standard deviation (SD) increment of BMI causally increased a 66.0% risk of AH (N = 371 SNPs, OR = 1.66, 95% CI 1.46-1.89, p = 1.55E-14) based on the IVW random effect model which was almost consistent with the results of other seven methods.
Our MR found genetic evidence for BMI and AH. The risk of developing AH increases with the number of BMI. This finding provides further evidence that maintaining a healthy BMI can prevent the development of AH. In addition, clinicians may need to focus on the potential risk of AH on some high-BMI patients.

Aim The outbreak of COVID-19 pandemic in January 2020 affected largely the elective operating for non-urgent surgical pathologies, such as hernias, due to periodical cancellations of the operating lists on a worldwide scale. To the best of our knowledge, the long-term impact of the COVID-19 pandemic in relation to the emergency hernia surgery operative workload and postoperative outcomes remains largely unknown. Methods Retrospective research of admission, operation and inpatient records of all patients who underwent emergency surgery over a 2-year period (2019-2020) was done. Results An 18% increase in terms of emergency hernia surgery operating volume, with a 23% increase of visceral resections due to unsalvageable herniated content strangulation was found. Overall morbidity did not increase during the pandemic period and there was no postoperative mortality or occurrence of COVID-19 related complications. Conclusion Emergency operative management of acutely symptomatic hernias can be safely performed even during the COVID-19 infection peak waves; hernia taxis should be reserved only for patients unfit or unwilling to undergo upfront surgery.

Quality of life (QoL) is an important outcome following surgery. The Carolinas Comfort scale (CCS) is a specific questionnaire used to evaluate QoL in patients who underwent abdominal hernia repair with mesh. The aim of this study was to create a Lithuanian version of the CCS.
A questionnaire-based cross-sectional study was conducted. A Lithuanian version of the CCS was created by translating the original questionnaire in accordance with the guidelines. The Lithuanian questionnaire was provided to hernia patients at 1 week and at 1 month postoperatively. The main validation characteristics of the Lithuanian CCS were assessed and compared to the original version.
The complete response rate of patients was close to 90%. Internal consistency was excellent, with a Cronbach\'s α of 0.953. Correlation coefficients ranged from 0.361 to 0.703 in the test-retest analysis. In the construct validity analysis, the strongest correlations were observed in the domains of physical functioning and bodily pain (- 0.655 and - 0.584, respectively) and the weakest correlations in role-emotional and mental health (- 0.268 and - 0.230, respectively). The mean scores of all CCS domains and the total score for satisfied patients were significantly lower (p < 0.001) than those of dissatisfied patients. The principal component analysis identified 3 components, with the first accounting for 56% of the variance.
The Lithuanian version of CCS maintains the original validity and is a reliable and valid tool for assessing specific QoL factors after the repair of inguinal hernia with mesh. We recommend using this CCS version in personal, local, and international contexts.

BACKGROUND: The utility of anterolateral thigh (ALT) + iliotibial tract (ITT) flaps for the reconstruction of large abdominal wall defects has been reported, especially in cases with huge skin defects, surgical contamination, or a history of radiotherapy. However, previous reports have mainly described short-term results such as flap success rates or incidence of wound complications. The present study reviewed 50 consecutive cases of abdominal wall reconstruction using an ALT+ITT flap after extensive tumor resection and evaluated the durability of this approach (incidence of bulge or hernia) and the factors affecting the results.
METHODS: A detailed retrospective review of 50 consecutive cases was conducted. Computed tomography or magnetic resonance imaging findings were reviewed to assess the incidence of abdominal bulge or hernia. Items extracted as variables from patient records were subjected to univariate and multivariate logistic regression analyses to identify their relationship with postoperative abdominal bulge or hernia.
RESULTS: Forty-six cases that were followed up for more than six months were analyzed. Twenty-three patients (50.0%) developed abdominal bulge, while none (0%) developed hernia. The multivariate logistic regression analysis revealed that old age and a high body mass index were independently associated with abdominal bulge, while abdominal defect size was not.
CONCLUSIONS: Abdominal wall reconstruction using an ALT+ITT flap after extensive tumor resection was considered a reasonable option with a low risk of hernia despite a marked incidence of postoperative abdominal bulge; however, the usage of additional material may be considered depending on the situation.

This study examined patient-related outcome measures (PROMs) after repair of ventral primary or incisional hernias using Symbotex™ composite mesh (SCM), a novel three-dimensional collagen-coated monofilament polyester textile.
Pre-operative, peri-operative, and post-operative data were obtained from the French \"Club Hernie\" registry with 12- and 24-month follow-up.
One-hundred consecutive patients (mean age 62.0 ± 13.7; 51% female) underwent repair of 105 hernias: primary (39/105, 37.1%, defect area 5.2 ± 5.6 cm2) and incisional (66/105, 62.9%, 31.9 ± 38.7.8 cm2). The mean BMI was 29.7 (± 5.6 kg/m2). American Society of Anesthesiologists classifications were I 39.4%, II 37.4% and III 23.2%. 75% had risk factors for healing and/or dissection. Of 38 primary repairs, 37 were completed laparoscopically (combined approach n = 1), and of 62 incisional hernia repairs, 40 were completed laparoscopically, and 20 by open repair (combined approach n = 2). Laparoscopic was quicker than open repair (36.2 ± 23.5 min vs. 67.4 ± 25.8, p < 0001). Before surgery, 86.3% of hernias were reported to cause discomfort/pain or dysesthesia. At 24 months (93 of 100 patients), 91 (97.8%) reported no lump and 81 (87.1%) no pain or discomfort. Of 91 patients, 86 (94.5%) rated their repair \"good\" or \"excellent.\" There were nine non-serious, surgeon-detected adverse events (ileus, n = 3; seroma, n = 6) and one hernia recurrence (6-12 months).
Compared to baseline, open and laparoscopic surgery improved PROMs 24 months after primary and incisional hernia repair. Minimal complications and recurrence support the long-term efficacy of SCM.
