P035 EMERGENCY BILATERAL GORIN HERNIA REPAIR IN UNILATERAL COMPLICATED INGUINAL HERNIA REAPIR WITH CONCOMITNAT CONTRALATERAL HERNIA. COHORTS COMPARATIVE OUTCOMES ANALYSIS USING PROPENSITY SCORE MATCHING

Abstract Aim Aim of our study was to analyze outcomes and safety of bilateral inguinal hernia repair in unilateral groin complicated hernia with contralateral groin hernia. Material and Methods Retrospective cohorts study following STROBE statements on a prospective Emergency Surgery Department database. Inclusion criteria were: patients with emergency hernia repair from 2008 to 2018, 18 years old. Unilateral or bilateral inguinal hernia repair without other abdominal wall hernia repairs. Comparative analysis between two group unilateral hernia repair (UH) vs bilateral hernia repair (BH) those patients with unilateral complicated inguinal hernia with contralateral inguinal hernia. Propensity score matching (PSM) between groups was performed to eliminate statistically groups differences. Outcomes between groups were analyzed with special attention to postoperative morbimortality and hernia recurrence. Results 341 patients were included, 38(11.1%) were performed bilateral hernia repair. Groups differences were: higher rate of inguinoscrotal inguinal hernia (36.8 vs 22.8), prophylactic antibiotics use (94.7 vs 81.8) and general Anesthesia use (52.6% vs 50.2%). General high rates of morbidity and mortality were observed (5.9% and 41.9) and 22 (6.5%) hernia repair recurrence were detected. After PSM no differences between surgery outcomes groups were observed with similar morbidity, recurrence or hospital stay. Conclusions Emergency inguinal hernia repair has high morbidity and mortality rates in our experience. Emergency Bilateral inguinal hernia repair in context of hernia complication seems safe without recurrence or hospital stay increase.

P104 POSTOPERATIVE OUTCOME AND COMPLICATIONS AFTER STOMA REVERSAL SURGERY WITH CICATRIAL HERNIA HERNIA PROPHYLAXIS BY MESH AUGMENTATION IN SUBLAY TECHNIQUE USING GORE® BIO A® MESH

Abstract Aim At the surgery hospital of Klinikum Mittelbaden in Baden-Baden (Prof. Dr. Dieter Berger) stoma reversal surgery was performed on 127 patients in the time from Nov. 15, 2010 to Mar. 11, 2015. All 127 patients were treated with a resorbable synthetic mesh (GORE® BIO-A® mesh) in sublay technique to close abdominal wall incisions. Primary wound closure was carried out in all cases. In order to evaluate the rate of postoperative hernias, which literature reports to be over 30 percent and a common complication, all 127 patients were included in a prospective study. Material and Methods In total, 104 of the included patients (n = 127) took part in the follow-up examinations. 72 patients underwent clinical examinations and imaging diagnostics, 21 were surveyed on the telephone whenever their presentation at a follow-up exam was impossible, whereas 11 patients deceased during the follow-up period. These cases were analyzed on the basis of the previous examinations which had been part of the respective health records. The follow-up examination took place after a median time span of 87 weeks (8 -218 weeks). Results The total herniation rate of 7.7 percent (n = 8/104) in the examined patient population was thus much lower than described in the literature. Conclusions According to our own prospective analysis, we were able to register a very low herniation rate compared to the literature when the resorbable synthetic mesh (GORE® BIO-A®) was applied in sublay technique for stoma reversal. One disadvantage could lie in the increased perioperative wound infection rate. 5/8 hernias were observed after the occurrence of perioperative wound infections.

Infectious and inflammatory complications after endoscopic hernioplasty in patients with postoperative ventral hernias: features of diagnosis and treatment strategies

An algorithm for the diagnosis and treatment of infectious and inflammatory complications after endovideosurgical hernioplasty in patients with postoperative ventral hernias using traditional and minimally invasive methods of therapy was proposed. The study was based on the treatment results of 177 patients who underwent endovideosurgery for postoperative ventral hernias. Despite the perioperative antibiotic prophylaxis according to the accepted at the S.M. Kirov Military Medical Academy, according to the protocol scheme (first-generation cephalosporin at a dose of 1 g once parenterally 30 min before the operation, followed by repeated administration in case of operation duration of 3 h), course of the early postoperative period on days 35 in 8 (4,5%) patients after endovideosurgical hernioplasty was complicated by suppuration in the intervention area. When analyzing the causes of infectious and inflammatory complications, in both the main and control groups of observations, all suppuration in the area of surgical interventions was diagnosed in patients with metabolic syndrome (stages IIIII obesity and type 2 diabetes mellitus). The use of the negative pressure wound therapy resulted in wound cleansing for 4.1 2.5 days (p 0.05) and was comparable with the traditional method of treatment, but more active growth of granulation tissue prevailed in the wound, which contributed to its accelerated healing. The negative pressure wound therapy is effective in the systemic infectious and inflammatory process, especially after prosthetic hernioplasty of large W3-postoperative hernias. Drainage of abscesses under ultrasound navigation is possible with small (S 10 cm2) delimited purulent processes in the area of the polypropylene implant with the preservation of the latter.

A one-stage, one-incision operation on the kidney, gallbladder and caecum under local anesthesia

The idea of the possibility of access from the lumbar incision to the liver, gallbladder and ducts is not new; there are numerous references to this in the literature (Fgapk, Meags, Tu ffieg, Wgight, Reboul, Trinkler, etc.). Frank, for example, even points to the benefits of a lumbar incision for surgery on the biliary tract in terms of convenience of postoperative treatment, convenience of drainage and less danger of postoperative hernias. Most recently, Hrtel) has been focusing the attention of surgeons on lumbar incisions for operations not only on retroperitoneal organs, but also for abdominal operations (spleen, pancreas, duodenum, colon, etc.). Without mentioning the whole issue here, I must say that the clinic has enough reasons for wanting to get operative access to the right kidney and gallbladder simultaneously. The first reason for this in normal conditions may be diagnostic difficulties. There are cases when the surgeon, exposing the kidney, simultaneously felt the stones in the gallbladder and was forced to continue the operation on the bile ducts from the same incision.

Incidence of Symptomatic Internal Hernia following Minimal Invasive colorectal surgery: A Single Center Experience

Laparoscopy has been adopted in the surgical specialties and colorectal surgery for treatment of benign and malignant diseases. Recent reviews suggest that the incidence of symptomatic internal hernias after laparoscopic colorectal resection is from 0.39 to 0.65%. Unlike in open surgery, laparoscopic closure of a mesenteric defect is inherently challenging as inadvertent injury to the marginal vessels may compromise blood supply to the anastomosis. For these reasons, many surgeons leave the defect open during laparoscopic surgery. But this may lead to development of post-operative internal hernia through the defect. This is a retrospective study where we included 149 patients who underwent laparoscopic/ robotic colorectal surgeries from March 2019 to March 2020. Data pertaining for following variables were collected which included age, sex, indication for surgery, location of the pathology, splenic flexure mobilization. The incidence of internal hernia among these patients were calculated and assessed using SPSS 20. Incidence of internal hernia was found to be 0.67% which was diagnosed and treated on the 18th post-operative day of initial surgery. Internal hernia is a rare but important complication of laparoscopic/robotic colorectal surgery with a high mortality rate if not diagnosed early. Defect closure is still controversial during the initial surgery and probably not indicated for all patients and depends on surgeon’s preference.

Comparative analysis of surgical interventions for postoperative ventral hernia in obese patients

The problem of surgical treatment of post­operative ventral hernias remains relevant today. Currently, a large number of methods of surgical interventions for hernias of the anterior abdominal wall have been proposed, the variety of which requires systematization and analysis of the immediate and distant results of treatment. Goal: to analyze the effectiveness of laparoscopic hernia repair in patients with postoperative ventral hernia with a body mass index of 30 kg/m2. The results of treatment of 29 patients with postoperative ventral hernia were analyzed. Men – 8 (27.5%), women – 21 (72.5%). In 16 (55.2%) patients (main group) laparoscopic intraperitoneal onlay mesh – IPOM was performed, in 13 (44.8%) patients (comparison group) open hernia repair with fixation of the mesh graft in the Sublay position was performed. The analysis of the duration of the surgical intervention indicates that with open hernia repair, there is a significant increase in the duration of the surgical intervention, p˂0.0001. Comparison of the duration of operations in both groups depending on the body mass index also indicates the dependence of the duration of surgery on this indicator. Thus, in the comparison group, there was a tendency to an increase in the duration of the operation with an increase in the body weight of patients with a significant difference in the duration of the operation between the main group and the comparison. The duration of a patient's stay in the hospital and the occurrence of respiratory complications correlates with the level of postoperative pain and the duration of surgery. Postoperative complications in the form of fluid accumulations in the wound area of the abdominal wall depend on the method of surgery and the location of the mesh graft. The use of laparoscopic – IPOM in obese patients significantly improves the results of surgery by reducing the level of postoperative pain, shortening the duration of surgery, and the absence of complications in the early and late postoperative period. When choosing the method of surgical intervention in patients with postoperative ventral hernia, laparoscopic IPOM should be preferred.

Prehabilitation and Nutrition in Hernia Surgery

AbstractVentral hernia repair (VHR) is among the most frequently performed surgical procedures in the United States. Despite advancements in surgical technique, a significant number of VHR patients experience postoperative complications and hernia recurrence. A key strategy to reduce VHR morbidity is patient optimization before surgery with prehabilitation protocols. Prehabilitation aims to improve patients' functional status with physical conditioning, nutritional intervention, and psychological support. In other surgical disciplines, prompt preoperative action has proven to significantly reduce the negative influence of modifiable comorbidities and accelerate recovery. In this article, we review the literature to assess the applicability and benefits of prehabilitation in elective VHR cases. A review of the available evidence identified obesity, hyperglycemia, and smoking as significant modifiable risk factors that negatively affect VHR outcomes. Prehabilitation has the potential to mitigate and control these comorbidities. Physical conditioning with aerobic, resistance, and inspiratory muscle training is beneficial. Nutritional intervention to control diabetes and in severely malnourished patients is especially important in patients undergoing concomitant gastrointestinal procedures with VHR. Reasonable targets for prehabilitation protocols in elective VHR include a body mass index of 35 kg/m2, HbA1C of 6.5% and tobacco abstinence for at least 4 weeks. Prophylactic measures to minimize the rates of incisional hernia after primary laparotomy repairs include mesh reinforcement and a suture to wound length ratio of at least 4:1.

Replacement of an extensive chest wall defect in combination with the elimination of postoperative ventral hernia after combined treatment of breast cancer complicated by osteomyelitis of the sternum and ribs

Plastic replacement of osteochondral defect of the chest wall after surgical treatment of osteomyelitis of the sternum and ribs is a complex and topical issue in surgery. Often, an extensive post-resected defect of the sternum and ribs is combined with instability of the frame of the chest wall and thoracoabdominal hernia, which leads to physiological and socio-psychological maladaptation of the patient. The case of successful replacement of an extensive chest wall defect in combination with a ventral hernia in a patient after combined treatment of breast cancer complicated by osteomyelitis of the sternum and ribs is presented. TiNi- reinforcing rib prostheses and TiNi-mesh were used to create the frame of the chest wall and hernioplasty. 5-year follow-up did not reveal a recurrence of osteomyelitis and ventral hernia, implant displacement and instability of the frame of the chest wall. The method of reconstruction of an extensive thoracoabdominal defect using bioadaptive implants from TiNi is safe and effective in patients at the final stage of surgical treatment of osteomyelitis of the chest wall including in combination with ventral hernia. Thanks to the developed technology, an excellent functional result was achieved.

Experimental study on an alternative to suturing the laparotomy wound with a mesh thread

BACKGROUND: Incisional ventral hernias (IVH) in abdominal surgery remain relevant because the frequency of their formation after laparotomy reaches 10%30.7%.
 AIM: This study aimed to develop a method for the primary closure of a laparotomy wound via mesh endoprosthesis, which is superior to laparorrhaphy with traditional suture materials in terms of morphophysical properties.
 MATERIALS AND METHODS: Laparorrhaphy with a mesh thread was developed (Patent for invention RUS No 2714439 02/14/2020) as an alternative to preventive prosthetics with narrow indications to avoid herniation. An experimental work was conducted to investigate the wound process in the suture area on days 14 and 60 and determine the effectiveness and safety of the proposed method.
 RESULTS: Video laparoscopy data showed that no cases of adhesions were observed between the internal organs and the area of laparorrhaphy on days 14 and 60 of the postoperative period. Defects in the area of the application of sutures on the aponeurosis of the white line were absent. In the wound, the mesh thread fully integrated into the regenerating tissue, including at the site of the knot. The tissue also grew through the meshed cells. On day 14, the strength of the regenerating tissue with the sutured mesh thread was greater than that sutured without it (11.198 1.499, p 0.01). This finding was confirmed by the larger area of granulations and fibrosis in cases of mesh suture than that of the checkerwise-reinforcing suture, suture with a mesh thread, and suture with a strip of mesh endoprosthesis. Another peculiarity of the connective tissue newly formed in the area of the mesh endoprosthesis in the form of the mesh thread was that collagen fibrils were arranged concentrically. By contrast, the mesh strip had collagen fibrils arranged in a longitudinal orientation parallel to the endoprosthesis. On day 60 of the experiment, all the series showed signs of maturation of the connective tissue in the form of the predomination of fibrils in cellular elements and their compaction. The area of fibrosis and granulations still prevailed in cases of the mesh suture, where neocollagenogenesis in the cells of the endoprosthesis was more pronounced than that after the application of a reinforcing suture, a mesh thread, and a strip of mesh endoprosthesis.
 CONCLUSION: The absence of wound complications and negative impact on the surrounding tissues indicated the safety of using the mesh suture. The strengthened characteristics associated with the peculiarities of the wound process showed that the mesh suture was effective in preventing the occurrence of postoperative hernia. Therefore, this method could be used in clinical practice.

Modern aspects of allohernioplasty of postoperative ventral hernias (a literature review)

The aim. Based on the data of the publications of herniologists for the last 5 years to examine the effectiveness and safety of prosthetic materials used in hernioplasty of postoperative ventral hernias. According to surgeons, the incidence of postoperative ventral hernia is up to 20 % of performed laparotomies, and if risk factors are present – up to 70 %. This problem was considered solved by the use of prosthetic mesh that became the standard of surgical approach in hernia repair since a recurrence rate was reduced to 20 %. However, the results of histological examination and body biological responses to an implant showed chronic inflammatory processes due to use of prosthetic material, especially polypropylene, causing purulent-inflammatory complications and intraperitoneal adhesion in 20.0–45.8 %. To prevent adhesion, a special barrier layer was applied on the polypropylene mesh, a process of mesothelial epithelialization (formation of the neoperitoneum) was supposed to occur, thereby reducing the risk of adhesions. A temporary nature of the barrier coating, where adhesion may develop at any time after implantation resulting in complications, has proven to be a potential problem of composite prostheses. There has been an attempt to address the challenge by using biological meshes made of decellularised pig and bovine dermis. However, recurrence rates after repair of hernia using the biological meshes was 6.3–61.0 %, wound infection – 16.0 %. Conclusions. Thus, world publications have proved today that it is impossible to perform adequate hernioplasty of postoperative hernias without the use of prosthetic material. However, complications and recurrences of the disease remain quite high. In order to improve these indicators, a sufficient number of studies were conducted, the effect of various prosthetic meshes on the patient body and on the postoperative wound itself was examined. Nevertheless, all the results are often contradictory, without specific conclusions about the indications for the use of method and type of prosthetic material.

Hernioabdominoplasty after obstetric and gynecological operations in obese patients

Statistics on the healing of obstetric and gynecological laparotomies with the formation of postoperative ventral hernias indicate a correlative and pathogenetic link with abdominal obesity in these patients, and inflammatory complications of subsequent corrective hernioplasty often have the same cause. The aim of the study was to improve the clinical and aesthetic results of surgical treatment of patients with hypogastric postoperative ventral hernias and scarring of the anterolateral abdominal wall on the background of abdominal obesity. The work is based on the analysis of paraoperative studies of 30 patients. The main group consisted of 19 patients who had umbilical-hypogastric postoperative ventral hernias of various sizes and locations after lower laparotomies or laparoscopic interventions. The comparison group included 11 patients who had only soft tissue deformities of the anterior abdominal wall without aponeurotic defects and hernias. Statistical processing of the results was performed using the software "Statistica 6.1". During the analysis of the obtained data it was found that parahernian excess tissues of the anterolateral abdominal wall after obstetric and gynecological operations have mainly supraaponeurotic localization and metric characteristics determined by the set size of the hernia, the severity of surrounding fatty layers and fibro-scar components. When performing hernioabdominoplasty in the conditions of ALAW obesity in patients with umbilical-hypogastric postoperative ventral hernias, sound tactics of dermolipectomy/fibrolipectomy were introduced in combination with abdominoplasty. This combination of surgical interventions reduces the incidence of local complications of hernia surgery to 4.5 %.

Diaphragmatic herniation after esophagogastric surgery: systematic review and meta-analysis

IntroductionThe anatomy of the esophageal hiatus is altered during esophagogastric surgery with an increased risk of postoperative hiatus hernia (HH). The purpose of this article was to examine the current evidence on the surgical management and outcomes associated with HH after esophagogastric surgery for cancer.Materials and methodsSystematic review and meta-analysis. Web of Science, PubMed, and EMBASE data sets were consulted.ResultsTwenty-seven studies were included for a total of 404 patients requiring surgical treatment for HH after esophagogastric surgery. The age of the patients ranged from 35 to 85 years, and the majority were males (82.3%). Abdominal pain, nausea/vomiting, and dyspnea were the commonly reported symptoms. An emergency repair was required in 51.5%, while a minimally invasive repair was performed in 48.5%. Simple suture cruroplasty and mesh reinforced repair were performed in 65% and 35% of patients, respectively. The duration between the index procedure and HH repair ranged from 3 to 144 months, with the majority (67%) occurring within 24 months. The estimated pooled prevalence rates of pulmonary complications, anastomotic leak, overall morbidity, and mortality were 14.1% (95% CI = 8.0–22.0%), 1.4% (95% CI = 0.8–2.2%), 35% (95% CI = 20.0–54.0%), and 5.0% (95% CI = 3.0–8.0%), respectively. The postoperative follow-up ranged from 1 to 110 months (mean = 24) and the pooled prevalence of HH recurrence was 16% (95% CI = 13.0–21.6%).ConclusionsCurrent evidence reporting data for HH after esophagogastric surgery is narrow. The overall postoperative pulmonary complications, overall morbidity, and mortality are 14%, 35%, and 5%, respectively. Additional studies are required to define indications and treatment algorithm and evaluate the best technique for crural repair at the index operation in an attempt to minimize the risk of HH.

ХИРУРГИЧЕСКАЯ ТАКТИКА ПРИ ПОЛИПАХ ЖЕЛЧНОГО ПУЗЫРЯ

Background. Due to the use of modern diagnostic technique the detection rate of gallbladder polyps constitutes 3-6%, and the number of cholecystectomies for polyps reaches up to 10% of all operations on this organ. Objective. To evaluate diagnosis and treatment outcomes in patients with gallbladder polyps and to define specific indications for surgical treatment (on the basis of a large number of observations). Material and methods. The article evaluates diagnosis and treatment outcomes in 237 patients with gallbladder polyps. Results. 235 (99,2%) patients underwent laparoscopic cholecystectomy. 2 (0,8%) patients with concomitant postoperative ventral hernia underwent herniolaparotomy, open cholecystectomy, anterior abdominal wall repair using a polypropylene mesh. Conclusions. Patients with small polyps (up to 5 mm) undergo follow-up ultrasound examination every 6 months; in case of doubtful findings CT or MRI of the gallbladder should be performed. The patients with medium polyps (5-10 mm) undergo laparoscopic cholecystectomy provided the polyps are multiple or with a broad base, otherwise such patients are followed-up. Laparoscopic cholecystectomy should be performed in case of large polyps or in patients with gallstone disease regardless of polyp size.

Abstract No. 523 Pre-operative Botox injection for ventral hernia repair: early experience at a single institution

Ventral wall hernias are a common pathology occurring in 10% of open abdominal operations. Surgical management of hernias can be complex due to chronic muscle contraction resulting in recurrence and significant morbidity. Botulism Toxin A (BTA) has been described as a preoperative therapy utilized to reduce muscle contraction and increase intrabdominal volume. Interventional radiologists may increase procedural accuracy while reducing complications by utilizing ultrasound (US) guidance; however, corresponding literature and data are sparse. The present study describes the efficacy and safety of pre-operative US-guided BTA injection in patients undergoing ventral abdominal wall hernia repair at a single institution. Eight patients underwent BTA injection from 2018 to 2020. Injections were performed via ultrasound guidance targeting the external oblique, internal oblique, and transversus abdominis muscles at three locations along the right and left lateral abdominal wall. Retrospective chart review was performed documenting date of birth, sex, preoperative hernia size by computed tomography (CT) evaluation, postoperative hernia size by CT evaluation, post-operative clinical assessment of hernia repair, number of injections, units of Botox, complications, use of mesh, date of repair, and technical success. Technical success was considered to be the ability to inject the BTA in the target muscles. The cohort consisted of 25% (2/8) women and 75% (6/8) men with an average age of 43.3 ± 8.1 years. The maximal pretreatment diameter of the hernia defect prior to surgery was 14.7 ± 4.6 cm. The technical success was 100% (8/8). The patients each had a total of 18 injections and 7/8 (87.5%) had 300 units of BTA while 1/8 (12.5%) had 240 units of BTA injected. None of the patients suffered complications from the injections. The patients underwent hernia repair at an average of 34.7 ± 4 days following BTA injection. Twenty percent (1/5) of patients did not require mesh insertion. Pre-operative US-guided BTA injection is a safe procedure that can aid in ventral abdominal hernia repair via induction of flaccid paralysis.

СИМУЛЬТАННЫЕ ОПЕРАЦИИ ПРИ ЭХИНОКОККОЗЕ ПЕЧЕНИ

Objective. To evaluate the results and effectiveness of simultaneous operations for echinococcosis of the liver. Methods. Surgical diseases requiring surgical treatment (cholelithiasis: calculus cholecystitis, choledocholithiasis, nodular goiter, ventral postoperative hernia) were detected in 38 patients with echinococcosis of the liver. 23 patients underwent organ-preserving operations for echinococcosis, and 15 patients underwent radical operations, all operations were perfomed in combined with cholecystectomy, choledocholitotomy, thyroidectomy, and herniotomy (coating of a polypropylenemesh for hernia gate).Immediate and remote results were studied. Patients were reexamined 6 months after surgery within a 3-year period. The examination included the checkup, general blood test, liver and kidney tests, an ultrasound examination of the abdominal organs, and a chest x-ray once a year. Results. During theimmediate postoperative period 4 patients out of 38 (10.5%) had complications. After simultaneous operations using organ-preserving methods of echinococcectomy, 2 patients out of 23 (8.7%) had complications (pleuritis, wound suppuration), and 2 - out of 15 had radical operations (bile leakage, pleuritis). All complications had been cured by the time of discharge. The remote results were studied over a period of 6 months to 3 years. 34 patients were examined up to 1 year, 31 - from 1 to 2 years, 26 - from 2 to 3 years. Within the examination and follow-up periods no recurrence of echinoccosis was observed. Conclusion. During simultaneous operations and the echinococcectomy of the liver it is necessary to observe accurately the rules of aparasiticity and antiparasiticity.Simultaneous operations for the liver echinococcosis should be performed according to strict indications and by a highlyexperiencedandqualified surgeon. Patients who have undergone simultaneous operations was asked toundergoa medicalcontrol examination at least once a year. What this paper adds The possibility of performing simultaneous operations for echinococcosis of the liver has been defined. The sequence of operations for echinococcosis in combination with other pathologies requiring surgical treatment has been justified.

Extraperitoneal versus transperitoneal approach for robot-assisted radical prostatectomy: An updated systematic review and meta-analysis.

261 Background: Extraperitoneal RARP (EP-RARP) has recently become a popular surgical approach and is often compared to the transperitoneal RARP (TP-RARP). We conducted a systematic review and meta-analysis of the available literature to evaluate the differences in peri-operative characteristics, oncological and functional control, and surgical complications between EP-RARP and TP-RARP. Methods: A comprehensive search of PubMed, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), ClinicalTrials.gov, Google Scholar, and select conference abstract publications was performed for eligible studies comparing outcomes between EP-RARP versus TP-RARP. This was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and was prospectively registered with PROSPERO. A leave-one-out sensitivity analyses was performed to control for heterogeneity and risk of bias. Results: A total of 16 studies (three randomized controlled trials, five prospective, and eight retrospective studies) were included with a total pooled population of 3897 patients including 2201 (56.5%) EP-RARPs and 1696 (43.5%) TP-RARPs. When compared to TP-RARP, EP-RARP offers faster operative time (MD: -14.4 minutes; 95% CI: -26.3, -2.3; p = 0.02), decreased length of post-operative stay (MD: -0.9 days, 95% CI: -1.3, -0.4, p < 0.0001), decreased rates of post-operative ileus (RR: 0.2, 95% CI: 0.1, 0.7, p = 0.009) and inguinal hernia formation (RR: 0.2, 95% CI: 0.1, 0.5, p = 0.001). There were no significant differences in total complications, estimated blood loss, positive surgical margins, or urinary continence at 6 months post-RARP. Conclusions: Based on the available evidence, EP-RARP delivered similar oncological and functional outcomes, while also offering faster operative time, decreased length of post-operative stay, and decreased rates of post-operative ileus and inguinal hernia formation when compared to the TP-RARP. These findings provide evidence-based data for surgical approach optimization and prompts future research to examine whether these findings hold true with recent advances in single-port RARP and outpatient RARP.

Umbilical Fascial Defects are Common and Predict Trocar Site Hernias After Laparoscopic Appendectomy.

Investigations have demonstrated that trocar site hernia (TSH) is an under-appreciated complication of laparoscopic surgery, occurring in as many as 31%. We determined the incidence of fascial defects prior to laparoscopic appendectomy and its impact relative to other risk factors upon the development of TSH. TSH was defined as a fascial separation of ≥ 1 cm in the abdominal wall umbilical region on abdominal computerized tomography scan (CT) following laparoscopic appendectomy. Patients admitted to our medical center who had both a preoperative CT and postoperative CT for any reason (greater than 30 days after surgery) were reviewed for the presence of TSH from May 2010 to December 2018. CT scans were measured for fascial defects, while investigators were blinded to film timing (preoperative or postoperative) and patient identity. Demographic information was collected. 241 patients undergoing laparoscopic appendectomy had both preoperative and late postoperative CT. TSH was identified in 49 (20.3%) patients. Mean preoperative fascial gap was 3.3 ± 4.3 mm in those not developing a postoperative hernia versus 14.8 ± 7.3 mm in those with a postoperative hernia (P < .0001). Preoperative fascial defect on CT was predictive of TSH (P < .001, OR = 1.44), with an Area Under the Curve (AUC) of .921 (95%CI: .88-.92). Other major risk factors for TSH were: age greater than 59 years (P < .031, OR = 2.48); and obesity, BMI > 30 (P < .012, OR = 2.14). The incidence of trocar site hernia was one in five following laparoscopic appendectomy. The presence of a pre-existing fascial defect, advanced age, and obesity were strong predictors for the development of trocar site hernia.

Modified technique of extraperitoneal colostomy without incision of the posterior rectus sheath

Extraperitoneal colostomy is a widely used technique during abdominoperineal resection (APR) operation for lower rectal cancer. This technique has been reported to be effective to prevent the postoperative parastomal hernia in some retrospective studies, however, there is still a certain incidence of parastomal hernia. A modification of the extraperitoneal colostomy technique is described in this paper that keeps posterior rectal sheath intact instead of having a conventional incision, to further reduce the risk of parastomal hernia. Until now, this modified technique has been performed in 15 patients, no occurrence of parastomal hernia was observed.

Prevention of ventral hernias using a new technique for accessing the abdominal cavity through the midline of the abdomen with dissection of the navel and umbilical ring: comparison with traditional laparotomy

The problem of postoperative ventral hernias remains relevant due to the high frequency of their development — in 7–24% of patients.Aim.To evaluate the effectiveness of prevention of postoperative ventral hernias using a new technique of access to the abdominal cavity in comparison with traditional laparotomy.Materials and methods.The proposed new technique of access to the abdominal cavity along the midline of the abdomen with dissection of the navel and umbilical ring was carried out in accordance with the method developed by us, registered by the patent of the Russian Federation. For the final analysis, 134 patients were selected, divided into group 1 (n = 67), in which the median access was performed using a new technique, and group 2, in which the traditional median access was performed with the left umbilical ring bypass (n = 67). The initial parameters of patients, characteristics during and after surgery were evaluated. The duration of follow-up after surgery was 24 months.Results.Groups 1 and 2 were comparable by gender, age, body mass index, and the presence of comorbidities. In 79% of patients in group 1 and in 67% of patients in group 2 (the difference is not significant), indications for surgery were malignancies of the abdominal cavity. The groups did not differ in the types of median laparotomy, the time of surgery, the amount of blood loss, the time of removal of postoperative sutures, and the duration of hospitalization. All patients were followed up for 24 months. Postoperative ventral hernia developed in one patient (1.5%) in group 1 and in 5 (7.5%) patients in group 2 within 12 to 24 months after surgery. There were no statistically significant differences in the frequency of hernia development (Mantel — Cox test, p = 0.100)Conclusion.A new method of median laparotomy in the treatment of patients with planned surgical pathology of the abdominal cavity is characterized by a low rate of postoperative hernia development.

Technical aspects of performing a transumbilical midline laparotomy

Aim to present a new midline approach technique with dissection of the navel and umbilical ring, that allows to reduce the number of postoperative ventral hernias after median laparotomy.&#x0D; Material and methods. The study involved 230 patients operated using the median approach with the transumbilical technique and with the traditional technique of midline laparotomy with a bypass of the umbilical ring on the left. The observation period lasted from 2016 to 2021.&#x0D; Results. The observation helped to assess the course of the postoperative period and the long-term outcome in the area of the surgical intervention on the abdominal wall. The advantages of the proposed technique were determined.&#x0D; Conclusion. When performing an access with a dissection of the umbilical ring, a strict compliance with the sequence of actions of suturing the laparotomic wound is of great importance. For the prevention of postoperative ventral hernias, it is important to combine the methods of access and suturing of the median laparotomic wound.
