Authors: Kupriyanova M V , Evdokimova E N , Soloviova I P , Simikova I P 
Published: December 2021

AbstractThe article displays the results of comparing the digitalization process in agrarian and industrial production. The objects of study are the companies of the eighty-two Russian regions. The information was obtained from open-access resources of the Russian State Statistics Bureau. The research aims at revealing the differentiation and the specific interconnection of digital transformation in agriculture and industrial production at the regional level. The observations prove the idea that the digitalization path and tempo depend on the unique regional conditions and the accumulated level of scientific and innovative potential. A controversy is revealed in the methodology of evaluating the digital maturity rate which was proposed by the Russian regulators for assessments at the federal and regional scale. The methodology implies equal weights of significance attributed to various sectors when measuring the regional level of digital transformation. Consequently, the socioeconomic context of the diverse regional systems is treated as a barrier to digitalization and an obstacle to intensive development. At the same time, it is a question of open discussion if digitalization of such peculiar sectors as agriculture and industrial production should be measured with similar methods.

Abstract
The paper presents the results of the scientific and economic experiment for the evaluation of the influence of the energy supplement included in the diet of lactating cows of the Brown Swiss breed. During the research period, all animals were kept in the same conditions, corresponding to zootechnical standards. They were divided into two groups differentiated only by the feed ration. The cows of the first (control) group were given rations typical for the farm corresponding to the feeding norms of dry and lactating cows. For the cows of the second group in the dry period (14 days before calving) the feeding ration was changed with a change in structure towards an increase in the proportion of concentrated feed, and immediately after calving, they received an energy feed supplement to maintain the physiological status of dairy cows after calving. Only clinically healthy animals participated in the experiment. It was revealed that the inclusion of the energy feed supplement in the diet of lactating cows in the experimental groups during lactation led to an increase in the productivity of livestock as compared with those in the control group.

Published: December 2021

Abstract
The newly reported 2D material ‘borophene’ provides a novel building block for nanoscale materials and devices. In this work, the linear and nonlinear plasmonic response of the electric dipole (ED) moment in metallic borophene is theoretically investigated. In our proposed model, a borophene nanostructure is deposited on the top of a dielectric layer sandwich with a silver layer acting as a mirror. It was found that the scattering at the scattering peak originates mainly from the exciting total ED. Our calculations demonstrate that scattering in the proposed model can be tuned well with carrier relaxation time, effective electron mass and free carrier density. The strongly localized fundamental field induces the desired increase in the second harmonic wave, which is discussed in detail by introducing the second-order nonlinear source. In addition, the evolution of the lifetime of linear and nonlinear plasmonic modes is also investigated, which helps us to study the underlying mechanism of microprocessing in the borophene plasmonic–photonic interaction. The manipulation of plasmonic behaviour and lifetime evolution makes borophene an excellent platform for tunable plasmonic–photonic devices.
Spatial personalities: a meta-analysis of consistent individual differences in spatial behavior
Authors: Stuber Erica F , Carlson Ben S , Jesmer Brett R 
Published: December 2021

AbstractIndividual variation in behavior, particularly consistent among-individual differences (i.e., personality), has important ecological and evolutionary implications for population and community dynamics, trait divergence, and patterns of speciation. Nevertheless, individual variation in spatial behaviors, such as home range behavior, movement characteristics, or habitat use has yet to be incorporated into the concepts or methodologies of ecology and evolutionary biology. To evaluate evidence for the existence of consistent among-individual differences in spatial behavior – which we refer to as “spatial personality” – we performed a meta-analysis of 200 repeatability estimates of home range size, movement metrics, and habitat use. We found that the existence of spatial personality is a general phenomenon, with consistently high repeatability (r) across classes of spatial behavior (r = 0.67–0.82), taxa (r = 0.31–0.79), and time between repeated measurements (r = 0.54–0.74). These results suggest: 1) repeatable spatial behavior may either be a cause or consequence of the environment experienced and lead to spatial personalities that may limit the ability of individuals to behaviorally adapt to changing landscapes; 2) interactions between spatial phenotypes and environmental conditions could result in differential reproduction, survival, and dispersal, suggesting that among-individual variation may facilitate population-level adaptation; 3) spatial patterns of species' distributions and spatial population dynamics may be better understood by shifting from a mean field analytical approach towards methods that account for spatial personalities and their associated fitness and ecological dynamics.

Published: December 2021

Abstract

Aim
This study aims to describe the early results after implementing a robotic ventral hernia repair (RVHR) program in a European university center.

Material and Methods
All patients undergoing primary (PH) or incisional (IH) RVHR were included in an institutional open-label prospective quality database. Patients' baseline characteristics, intra-operative data, postoperative, and follow-up outcomes recorded from September 2018 to September 2020 were analyzed.

Results
Twenty-six PH and 58 IH were included; respectively, mean BMIs were 32.8±7.1 and 30.3±5.0kg/m2. Hernia resulted from median laparotomies in 69.0% of the IH patients; 5 patients (8.6%) had defects &gt;10cm in width. In the PH group, the mean total operative room (OR) time was 98.1±42.5min. Mean VAS (Visual Analog Score) was 2.5±1.7 at day 0, 61.5% of patients were ambulatory, and 38.5% stayed 1-2 nights. One (3.8%) recurrence and 1(3.8%) surgical complication (umbilical perforation) occurred with no general complications. In the IH group, 15 patients required transversus abdominis release (TAR, 25.9%). Mean OR time was 179.6±82.3min, mean VAS 1.9±2.0 at day0, 19% of patients were ambulatory, 44.8% stayed 1-2 nights and 27.6% 3-4 nights. Mean follow-up was 71.6±51.8 days. One (1.7%) postoperative complication (bleeding, embolization, no reoperation), 2(3.4%) recurrences occurred. Successful completion of an extraperitoneal (eTEP) RVHR with bilateral TAR was achieved after 18 months and 40 cases, after which we began training a second surgeon.

Conclusions
Implementation of a RVHR program showed promising results with acceptable operative time even during the learning curve. Postoperative outcomes suggest a potential advantage in postoperative recovery.

Abstract

Aim
After a long experience of more than 20 years in TEP hernioplasty we explore if it can also be suitable for emergency patients.

Material and Methods
We present different laparoendoscopic schemes that we have used in our Hospital to treat strangulated inguinal hernia according to clinical and radiological findings.

Results
TEP in now assumed to be one of the best options in scheduled surgery to treat inguinal hernia. Is now the time to change the paradigm by using it also in emergency surgery?
Incarcerated inguinal hernia presents two problems: first of all the clinical emergency, an irreducible inguinal bulge that causes pain, obstruction and bowel ischemia; and second, the need to repair inguinal wall.
While treating both problems, we have explored different minimally invasive surgery approaches according to each patient´s characteristics and the preoperative risk of intestinal resection based on CT findings.
To reduce the incarcerated bulge, we use a laparoendoscopic methods. After a preperitoneal dissection, and with the help of external maneuvers, we try to reduce the content. If we are not successful, a quelotomy becomes necessary.
To treat the inguinal defect we use TEP or TAPP approaches.

Conclusions
We seek to show that endoscopic preperitoneal approach in an incarcerated inguinal hernia is safe and possible, allowing us to maintain minimal invasive techniques.
Laparoscopy allows us to explore and to treat possible complications of intestinal ischemia with no need of laparotomy.
Multiple treatment schemes are possible for inguinal incarcerated hernia. The choice must be made according to the surgeońs experience, patient´s characteristic and the risk of intestinal ischemia.
P039 INTERCOSTAL HERNIA FOLLOWING DIEP RECONSTRUCTION: A CASE PRESENTATION
Authors: Robinson Jordan , Robinson John 
Published: December 2021

Abstract

Aim
Intercostal lung herniation is a rare clinical condition defined as the protrusion of lung parenchyma beyond the anatomic boundaries of the thoracic wall. Acquired lung hernias are typically occur secondary to trauma or are associated with severe pulmonary disease. We present a case of lung herniation following DIEP breast reconstruction which is the first reported case to date.

Material and Methods
40-year-old woman with a history of bilateral mastectomy for breast cancer and subsequent delayed, bilateral DIEP breast reconstruction. She returned to the emergency department four days after her reconstruction with chest pain, shortness of breath and swelling of her chest. CT angiography of her chest demonstrated a focal protrusion of her right lung into her anterior chest wall (Figure 1). Thoracic surgery was consulted for repair which was achieved with a patch technique using Allomax dermal matrix.

Results
We describe the first reported intercostal lung hernia following DIEP breast reconstruction reported in scientific literature. Our patient had no history of trauma, thoracic surgery or pulmonary disease which are considered the greatest risk factors for acquired intercostal lung herniation. Much like abdominal wall hernias, protrusion of tissue through a small defect places tissue at risk for ischemia. Early recognition is thus essential to avoid tissue loss.

Conclusions
Intercostal lung hernia is an uncommon clinical entity that has not previously been described as a complication of DIEP breast reconstruction. Its development is associated with significant morbidity including flap loss in this case. Early recognition of this rare complication is essential to avoid more severe sequelae of tissue ischemia.
P047 SUTURE-TOOL: A SUTURING DEICE FOR SWIFT AND STANDARDIZED ABDOMINAL APONEUROSIS CLOSURE
Authors: Börner Gabriel , Edelhamre Marcus , Rogmark Peder , Montgomery Agneta 
Published: December 2021

Abstract

Aim
Introduction Surgeons can reduce incisional hernia formation by adhering to standardized techniques for incisional wound closure. This is often neglected by the time a long operation is to be ended and can lead to the risk of developing an incisional hernia or a wound rupture. To address this issue, a suturing machine (Suture-TOOL) was developed for swift and standardized abdominal closure. The aim was to compare the user safety, speed, and suturing quality between Suture-TOOL and manual Needle-Driver suturing.

Material and Methods
Fifteen surgeons who were specialists in surgery, urology, and gynaecology as well as surgical trainees were invited. The Suture-TOOL was presented to the surgeons who read the instructions for use before starting the test. Each surgeon closed nine 15-cm-long incisions in a human body model; six with Suture-TOOL and three with the Needle-Driver technique. Gloves were examined for puncture damage. Endpoints were suture-length/wound-length (SL/WL)-ratio, closure time, number of stitches, learning curve, and glove puncture rate. A VAS-evaluation concerning different Suture-TOOL user impressions was completed.

Results
SL/WL-ratio ≥4 was 98% for Suture-TOOL versus 69% for Needle-Driver (p &lt; 0,001). Suture time was shorter for Suture-TOOL (p = 0,013). The median SL/WL-ratio was similar between the groups. The learning curve plateaued after three closures using Suture-TOOL. Two glove punctures were detected—all in the Needle-Driver group. Suture-TOOL received high VAS scores for all measured functionalities.

Conclusions
Suture-TOOL is a promising device for clinical use. It is safe, easy, and fast resulting in a high-quality suture lines with a short learning curve and a high functionality ranking.
P048 A NEW MODALITY FOR BIOMECHANICAL VALIDATION OF CLOSURE TECHNIQUES OF LAPAROTOMIES
Authors: Hartog Floris den , Sneiders Dimitri , Vlot John , Kleinrensink Gert-Jan , Jeekel Johannes , Lange Johan 
Published: December 2021

Abstract

Aim
Incisional hernia remains one of the most frequent complications after abdominal surgery. Several closure techniques exist. However, fundamental biomechanical understanding of these techniques and of the differences in clinical outcomes are still lacking. It is thought that distribution of lateral forces on the midline plays a role. Testing in a clinical setting is limited by sample sizes, costs and ethical regulations. We propose a preclinical ex vivo model in which multiple closure configurations can be tested in a controlled setting, eliminating interfering variables existing in previously published, more complex abdominal wall models. Consequently, this allows a valid comparison between closure modalities based on biomechanical merits.

Material and Methods
The experimental set-up is represented by a vertical tensile load tester, in which a sutured tissue sample is clamped. The tissue samples are covered with a fine, random speckle pattern via miniscule ink droplets. A high-resolution camera captures the speckles as the tissue is subjected to linear pulling forces. Image analysis documenting relative movement of speckles as a means for measuring tissue deformation is performed in ex-vivo tissue samples, resulting in specific objective biomechanical characteristics for each closure configuration.

Results
Local tissue strain fields are visualized, and compared between closure modalities and correlated to known linear forces applied to the tissue. The latest results will be shared and discussed.

Conclusions
A new modality for biomechanical evaluation of closure techniques has been developed. Further validation and serial experiments with different closure modalities with and without mesh reinforcement can be performed in order to determine the biomechanically optimal suture-technique for fascial closure.
P050 INTRODUCTION OF MINIMAL INVASIVE PROCEDURES WITH EXTRAPERITONEAL MESH PLACEMENT MAY REDUCE MORBIDITY AND LENGTH OF HOSPITAL STAY IN PATIENTS WITH INCISIONAL HERNIA - A SINGLE CENTER'S EXPERIENCE
Authors: Kundel Lena , Gröger Christian , Adam Ulrich , Riediger Hartwig 
Published: December 2021

Abstract

Aim
“Sublay mesh placement is the gold standard in the treatment of incisional hernias. In open surgery, high rates of wound complications are reported. Various minimal invasive procedures with extraperitoneal mesh placement (MIPEX) are currently under evaluation in order to improve the clinical results. We report our experience with an increased use of MIPEX techniques”

Material and Methods
“The perioperative results of all consecutive patients from 1/2018 to 4/2021with incisional hernia surgery were reviewed. For the purpose of this study, the results of patients with MIPEX were compared to STANDARD treatment (open surgery and/or intraperitoneal mesh). All patient data were registered prospectively in the Herniamed database. ”

Results
“103 out of 170 patients were treated with MIPEX and 67 with STANDARD. MIPEX were MILOS/E-MILOS (n = 48), TAPP (n = 15), laparoscopic sublay (n = 5), ETEP (n = 17) and other (n = 18) with additional TAR in (n = 16). Five procedures were performed robotically. Mean duration of surgery (DOS) was 150 minutes in MIPEX and 116 minutes in STANDARD (n.s.). Morbidity was 7% in MIPEX and 19% in Standard (p &lt; 0.5). Mean length of hospital stay (LHS) was 4 days in MIPEX and 8 days in STANDARD (p &lt; 0.5). In subgroup analysis of patients with large hernias (EHS-3, n = 31), DOS was 320 minutes (MIPEX) vs. 159 minutes (STANDARD); p &lt; 0.01 and LHS was 8 days (MIPEX) vs. 12 days (STANDARD), p &lt; 0.01.”

Conclusions
“MIPEX included a broad spectrum of procedures. With the implementation of MIPEX, DOS increased significantly in large hernias. Morbidity and LHS were significantly reduced in all patients.”
P052 EARLY OPERATIVE OUTCOMES OF ENHANCED-VIEW TOTALLY EXTRA PERITONEAL REPAIR(ETEP) FOR VENTRAL HERNIAS
Authors: Imamura Kiyotaka , Takada Minoru , Ambo Yoshiyasu 
Published: December 2021

Abstract

Aim
Early operative outcomes of enhanced-view totally extraperitoneal repair (eTEP) for ventral hernias

Material and Methods
We have retrospectively analysed the date of 41 patients who underwent an eTEP procedure on between November 2018 and April 2021 by a single surgeon and monitored until May 2021.

Results
During the study period, 29 endoscopic transversus abdominis muscle release and 12 endoscopic Rives-Stoppa techniques were performed to repair incisional (30), umbilical (6), epigastric (3), and spigelian, and parastomal hernias occurred in 1 patient each. The mean age was 68.0 years, mean BMI was 26.4 kg/m2. The hernial orifice centers were as follows: M2 in 7, M3 in 23, M4 in 5, L2 in 4, L4 in 1, and M2 and L2 (2 orifices) in 1 patient. Nine cases of large incisional hernia (width ≥10cm) were included. An average mesh area of 624cm2 was used for an average defect area of 57cm2. Mean operative time, blood loss, and length of hospital stay were 278 min, 5 ml, 6 days, respectively. Only one case was converted to an open operation due to presence of severe adhesions. Postoperative complication consisted of hematoma (n = 1) and a small bowel obstruction due to a tear of the posterior sheath (n = 1). There was no hernia recurrence at mean follow-up of 448 days. No patient reported significant pain at the surgical site at the first postoperative follow up.

Conclusions
Judging from our short-term results, eTEP approach for ventral hernias can be an attractive option for selected cases.
P056 RETROSPECTIVE ANALYSIS OF LONG-TERM INCIDENCE, RISK FACTORS AND SURGICAL REPAIR OF VENTRAL INCISIONAL HERNIAS AFTER LIVER TRANSPLANTATION
Authors: Augustin Cäcilia , Lorenz Andreas 
Published: December 2021

Abstract

Aim
“Assess risk factors and incidence of ventral incisional hernia (VIH) following liver transplantation (LT).”

Material and Methods
“Retrospective analysis of clinical or radiological signs of VIH during a systematic ten year follow up after liver transplantation. Descriptive statistics and a binary logistic regression analysis were performed to identify possible risk factors.”

Results
“Between 01/2007-12/2017, 708 LT were performed in 660 patients at our institution. Following LT, 122 patients (18.5%) had a VIH as identified per clinical examination. Further to this, 85 patients (12.9%) had CT findings consistent with VIH adding to a total of 207 (31.4%) patients with VIH after LT. Male gender (p &lt; 0.001), BMI (p &lt; 0.001), age at LT (p &lt; 0.001), alcohol induced cirrhosis (p = 0.032) and reoperation after 180 days following LT (p = 0.007) were identified as risk factors in a multivariate analysis. An incisional hernia repair was performed in 76 patients (11.5%) at 22.9 months (median, 5.7-101.5). Laparoscopic IPOM repair was performed in 46 (60.5%) patients and 30 patients had an open hernia repair including 26 (34.2%) with mesh augmentation and 4 (5.3%) with primary closure. Five patients (6.6%) needed a reoperation for postoperative complications related to hernia repair. Recurrent VIH occurred in 12 (15.8%) patients. In 131 patients, no hernia repair was performed because of only mild clinical symptoms, patient preference and/or poor general condition.”

Conclusions
“The incidence and burden of incisional hernia following LT is significant. Many cases of VIH are clinically mild but radiomorphologically manifest.”
P057 THE ACCURACY OF INCISIONAL HERNIA CODES IN ADMINISTRATIVE DATA: A VALIDATION STUDY
Authors: Rios-Diaz Arturo , Hsu Jesse Y. , Broach Robyn , Bormann Bradford , Fischer John 
Published: December 2021

Abstract

Aim
Administrative databases contain valuable information for studying incisional hernia (IH) following intra-abdominal procedures at a large scale. We assessed the validity of billing codes for the identification of IH in patients following abdominal surgery.

Material and Methods
Using International Classification of Diseases, Ninth and Tenth Revision, Clinical Modification (ICD-9-CM and ICD-10-CM), a random sample of 1,000 patients who underwent abdominal operations between 2006-2020 within a large health system-wide administrative database and ≥1 year of follow-up were screened for eligibility. Validation of IH codes was performed using the electronic medical record as reference. Validity metrics of interest included sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy. Patient factors associated with false positive (FP) and false negative (FN) were also explored within univariate and multivariate analyses.

Results
759 patients were included. The sensitivity of IH codes was 94.7% (CI 91.4 – 97.0), specificity was 94.9% (CI 92.6 – 96.7), PPV was 84.4% (CI 78.5 – 88.9), NPV was 98.4 (CI 97.4 – 99.0), accuracy was 94.9% (CI 93.0 – 96.3). Within adjusted analyses, patients admitted to a non-surgical service (relative to patients admitted to surgical services; OR 4.46 [95% CI 1.06-18.66]; p = 0.04) were associated with FP; whereas every one-year increase in age was associated with a 5.0% (95% CI 1.0%-10.0%) increase in FN (p = 0.03).

Conclusions
We have validated the use of ICD-9-CM and ICD-10-CM codes for accurately identifying IH following abdominal surgery. This method yields &gt;94% for key validity measures.
