RESUMO

OBJECTIVE: The aim of the study was to determine the possibility and effectiveness of simultaneous surgical interventions in umbilical and paraumbilical hernia repair. PATIENTS AND METHODS: Material and methods: 148 case histories were analyzed concerning patients who were routinely admitted to the surgical department of the Kharkiv Regional Council's Municipal Non-Profit Enterprise «Regional Clinical Hospital¼ between 2017 and 2019, and who underwent umbilical and paraumbilical hernia repair simultaneously with operations related to some other surgical pathology (group 1, n = 67) or in separate interventions (group 2, n = 81). All patients were routinely operated after a set of mandatory and additional general clinical, laboratory and instrumental research conducted in accordance with the existing guidelines. The structure and results of surgical interventions related to the underlying disease and simultaneous operations were studied. RESULTS: Results: Simultaneous operations were performed for comorbid cholecystolithiasis, diaphragmatic esophageal hernia with gastroesophageal reflux, inguinal hernia, white line hernia, benign diseases of the uterus and uterine appendages et al. The frequency of complications and recurrences of hernia in patients with simultaneous and isolated of umbilical hernia repair did not differ significantly. The outcome of the operation mostly depended on the method of operation (postoperative complications were most often observed in open sutures repair and were absent in laparoscopic hernia repair). Additional risk factors were weight gain and diabetes. CONCLUSION: Conclusions: Summarizing the data obtained, it can be concluded that application of modern endovideoscopic techniques in surgery makes simultaneous surgical interventions not only possible but also necessary in the presence of concomitant abdominal pathology that requires surgical treatment.

RESUMO

Using the mesh for hernia repair is the most common type of hernia surgery. There are many types of meshes made of various synthetic materials, but all of these meshes have their own respective disadvantages. The aim of this study was to provide preliminary results of a non-randomized clinical trial evaluation of novel porcine grafts XI-S+® (Colorado Therapeutics LLC. USA) for ventral and inguinal hernia repair. All patients underwent a standardized surgical procedure. Onlay surgical repair technique has been performed in ten patients with ventral hernia and Lichtenstein tension-free method has been used for ten patients with inguinal hernia repair. The XI-S+® mesh fixation was performed with multiple simple interrupted sutures using prolene thread. The average age of the patients with ventral hernia was 54±14 years, and 30% of patients were female and 70% of patients were male. The average age of the patients with inguinal hernia was 62.5±9.4 years, and 10% of patients were female and 90% of patients were male. The average hospitalization length was 2 days. During three years of observation, no recurrence of hernia was observed in patients. The XI-S + ® mesh has anti-adhesive properties, is extremely resistant to infections, provides favorable conditions for engraftment, early activity and patient rehabilitation. The clinical studies of the patients that underwent ventral and inguinal hernia repair using XI-S+® mesh have shown that the post-operative pain was minimal and easily controlled by the use of analgesics. As for the sensation of the mesh, in some patients it has been present up until 1 month from surgery, but it fully disappeared by the end of the 3rd month.

RESUMO

Ventral hernias, with the incidence of reherniation nearly as high as 50%, still remain to be a real challenge for surgeons worldwide. The use of mesh in the repair of abdominal wall defects reduces the incidence of reherniation; however, using a prosthetic mesh can lead to complications like wound infection, hematoma, seroma, enterocutaneous fistula, small bowel obstruction, recurrent herniation and erosion into adjacent structures including the intestine. The aim of the study was to develop a method for producing gelatin-coated decellularized and lyophilized human amniotic membrane graft and to determine its effectiveness for the reconstruction of the anterior abdominal wall defects. Experiments were conducted on 40 Lewis white laboratory rats. Animals were divided into four equivalent groups. Abdominal wall defects were created in all rats and repaired using the ULTRAPROTM mesh (group I), ULTRAPROTM mesh which was covered by decellularized and lyophilized human amniotic membrane from both sides (group II), mesh from gelatin-coated decellularized and lyophilized human amniotic membrane (group III) and biological surgical mesh XI-S+® (group IV). Three months after implantation, meshes from gelatin-coated decellularized and lyophilized human amniotic membrane were integrated with host tissues so that it was difficult to distinguish it from the surrounding tissues. However, in the second group, ULTRAPROTM mesh was still detectable through the decellularized amniotic membrane. Encouraging results were also observed when using a XI-S+® graft. Three months after implantation, XI-S+® graft was surrounded by a well-defined connective tissue capsule and was tightly fixed to the host tissues. While using gelatin-coated decellularized and lyophilized human amniotic membrane grafts and XI-S+® grafts, all the defects were repaired successfully and none of the rats in these groups showed any evidence of bulging or herniation, development of wound rupture, wound infection or fistula formation in postoperative period. Gelatin-coated Decellularized human amniotic membrane can be used as anti-adhesive barrier in abdominal and pelvic surgery, as well as for the repair of the abdominal wall hernia.

RESUMO

ABSTRACT: Surgical site infection (SSI) is a costly postoperative complication with a decrease in the quality of life. We aimed to probe the predictive role of peripheral blood inflammation markers for SSI following mesh repair of groin hernia (GH).This retrospective study assessed the data of 1177 patients undergoing elective mesh repair of GH (open/laparoscopy) in the absence of antibiotic prophylaxis. The relation between demographics, surgical factors, pre-surgical laboratory results and the occurrence of SSI were investigated by univariate and multivariate analyses. Receiver operating characteristic analysis was performed to determine the optimal threshold of parameters and compare their veracity.The overall SSI rate was 3.2% with 1-year follow-up (38 superficial and 1 deep SSI). Patients with SSI had significant higher pre-surgical neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) than those without (P = .029 and P = .045, respectively); their NLR and PLR correlated positively with postoperative total days of antibiotic treatment for SSI (r = .689, P = .000; r = .493, P = .001; respectively). NLR and PLR had larger areas under the receiver operating characteristics curves than neutrophil (.875 vs. .601; P = .000; .726 vs. .601; P = .017). The combination of PLR and neutrophil/NLR raised the predictive sensitivity of PLR for SSI (sensitivity: PLR: 74.36%; PLR + neutrophil: 82.05%; PLR + NLR: 83.57%). On multivariate analyses, higher preoperative NLR (cut-off 2.44) and PLR (cut-off 125.42) were independent predictors for SSI.Higher pre-surgical NLR and PLR may be valuable predictors for SSI following elective mesh repair of GH.

RESUMO

BACKGROUND: Laparoscopic paraesophageal hernia repair is associated with higher recurrence rate. Mesh is used to reduce the recurrence rate. This retrospective study is to review our experience of biological mesh fixed with suture and medical glue in hiatal hernias repairs. METHODS: A retrospective chart review was conducted for a consecutive series of patients undergoing laparoscopic hiatal herniorrhaphy between January 2018 and January 2019. After hiatus closure, a piece of biological prosthesis was fixed with medical glue and suture for reinforcement of the crural closure. Clinical outcomes were reviewed, and data were collected regarding operative details, complications, symptoms, and follow-up imaging. Radiological evidence of any size of hiatal hernia was considered to indicate a recurrence. RESULTS: Thirty-six patients underwent surgery uneventfully without any serious complication. There was no mortality. The follow-up was, on average, 18.4 months, and there was no symptomatic recurrence. There was one anatomical recurrence without any related presentation. The method of mesh fixation with medical glue and suture took 12 min on average, and the handling was fairly easy. CONCLUSIONS: Biological mesh fixed with suture and medical glue was safe and effective for repairing large hiatal hernias. Of course, a longer follow-up is still needed for determining long-term outcomes.

RESUMO

INTRODUCTION: currently, there are several clinical applications for robot-assisted surgery and in the hernia scenario, robot-assisted surgery seems to have the ability to overcome laparoscopic ventral hernias repairs limitations, facilitating dissection, defect closure, and mesh positioning. Exponentially grown in numbers of robotic approaches have been seen and even more complex and initially not suitable cases have recently become eligible for it. An appropriate tension-free reestablishment of the linea alba is still a major concern in hernia surgery and even with the robotic platform, dissecting and suturing in anterior abdominal wall may be challenging. This article reports a technical image artifice during a da vinci Xi-platform robotic ventral hernia repair allowing the surgeon to establish a more familiar and ergonomic manner to perform dissection and suturing in anterior abdominal wall. TECHNICAL REPORT: a step by step guided technique of image inversion artifice is described using detailed commands and figures to assure optimal surgical field and ergonomics whenever acting in robotic ventral hernias repair with the da Vinci Xi-platform. Our group brief experience is also reported, showing an easy and reproducible feature among surgeons with safe outcomes. CONCLUSION: we consider that image inversion artifice is a simple and reproducible feature in robotic ventral hernia repair. Through a step-by-step guide, this report enables the creation of an artifice providing a comfortable operative field and allowing the surgeon to achieve its best proficiency in hernia surgery.

RESUMO

Ventral and incisional hernias in obese patients are particularly challenging. Suboptimal outcomes are reported for elective repair in this population. Preoperative weight loss is ideal but is not achievable in all patients for a variety of reasons, including access to bariatric surgery, poor quality of life, and risk of incarceration. Surgeons must carefully weigh the risk of complications from ventral hernia repair with patient symptoms, the ability to achieve adequate weight loss, and the risks of emergency hernia repair in obese patients.

RESUMO

OBJECTIVES: To evaluate the safety and efficacy of transvaginal mesh surgery using a polytetrafluoroethylene mesh to treat pelvic organ prolapse. METHODS: This prospective observational study included women undergoing transvaginal mesh surgery for pelvic organ prolapse that used new polytetrafluoroethylene mesh cut into a shape similar to that of Elevate. We evaluated the subjective and objective outcomes at 3 and 12 months, as well as postoperative complication rates. RESULTS: This study included 55 patients. The pelvic organ prolapse quantification scores improved significantly at 3 and 12 months after surgery compared with scores before surgery. In four patients (7.3%), a pelvic examination showed stage 2 objective recurrence without subjective symptoms. Clavien-Dindo grades 2 and 3 perioperative complications were observed in 9.1% and 1.8% of the patients, respectively. Vaginal mesh exposure occurred in one patient (1.8%) at the time of the 3-month follow-up evaluation. The mesh was exposed at the proximal midline of the anterior vaginal wall. CONCLUSIONS: These findings show the safe and effective use of the polytetrafluoroethylene mesh for transvaginal mesh surgery.

RESUMO

Incisional hernia is a late complication of the most frequent after abdominal surgeries, with resulting morbidity that can worsen the condition. The treatment has been done both by open techniques, using screens or not, and by laparoscopic and robotic methods, which use them systematically. However, introducing a permanent foreign body into the tissues requires more surgical time, despite not closing the parietal defect in most cases and a higher risk of infections. New technologies have been trying to improve these results, with absorbable prostheses (biological or synthetic), but their high cost and recurrences remain a severe problem. Even so, standard repair establishes reinforcement with screens, routine, and whether the approach is traditional or mini-invasive. The authors report their first case of endoscopic repair of incisional hernia, which occurred two years ago, with a Brazilian technique already fifty years old: the transposition with the hernia sac proposed by Prof. Alcino Lázaro da Silva in 1971.

RESUMO

OBJECTIVE: To compare the clinical effects of three different methods of binding multi-fold rib graft, iliac bone graft and titanium mesh graft in tuberculosis of thoracic vertebra by approach of transverse rib process. METHODS: A hundred and seven patients with tuberculosis of thoracic vertebra received surgical treatment from January 2010 to December 2016 were retrospectively analyzed. The patients were divided into three groups according different methods of bone graft. The surgical approach of the transverse rib process was used in all 107 patients, after thoroughly remove the necrotic tissue of tuberculosis, three different bone grafts were used respectively including iliac bone graft (36 cases, group A), binding multi-fold rib graft (35 cases, group B), titanium mesh bone graft (36 cases, group C). Perioperative indexes, the time required for bone graft during operation, intraoperation blood loss, the loss rate of the anterior edge of the lesion, Cobb angle, postoperative bone graft fusion time, spinal nerve recovery and Oswestry Disability Index were compared among three groups. RESULTS: All the patients were followed up for 13 to 24 months, and the operation time required for bone graft was (23.2±4.1) min in group A, (23.8± 4.4)min in group B, and (25.5±4.2) min in group C, with no statistically significant difference among three groups (P>0.05). Intraoperative blood loss was (541.6±35.3) ml in group A, (546.8±27.8) ml in group B, and (540.1±34.5) ml in group C, withno statistically significant difference among three groups(P>0.05). Preoperative anterior vertebral height loss rate was (46.0± 3.1)% in group A, (46.4±3.3)% in group B, and (45.3±3.6)% in group B;at the final follow up, the loss rate of anterior vertebral height among three groups was (8.6±5.0)%, (8.1±4.2)%, (9.4±4.3)%, respectively. There were no statistically significant differences before operation and final follow-up among three groups (P>0.05). Preoperative Cobb angle was (35.1±4.8)° in group A, (35.2±4.5)° in group B and (35.2±4.5)° in group C, with no statistically significant difference among three groups (P>0.05);postoperative at 3 days, Cobb angle in three groups was (15.1±3.6)°, (15.3±3.1)° and (15.2±3.4)°, respectively, there was no statistically significant difference among three groups (P>0.05);at the final follow-up, the Cobb angle among three groups was (17.7±3.3)°, (17.9±3.9)°, (18.6±3.6)°, respectively, with no statistically significant difference among three groups (P>0.05). The time of bone graft fusion was (5.6±0.5) months in group A, (5.6±0.6) months in group B and (5.8±0.6)months in group C, with no statistically significant difference among three groups (P>0.05). Frankel classification at the final follow up, 4 cases were grade B, 7 cases were grade C, 10 cases were grade D, and 86 cases were grade E. Spinal nerve function in all three groups recovered to a certain extent after treatment, with no statistically significant difference among three groups (P> 0.05). Oswestry Disability Index at the final follow-up showed no statistically significant difference among three groups (P> 0.05). CONCLUSION: The approach of transverse rib process for debridement of lesions can effectively treat tuberculosis of thoracic vertebra by binding multi-fold rib graft, iliac bone graft and titanium mesh graft, but binding multi-fold rib graft can effectively avoid iliac bone donor complications, and is an effective alternative to iliac bone graft, which is worth popularizing.

RESUMO

Objective: To evaluate the short-term clinical efficacy and safety of transvaginal pelvic floor reconstruction with TiLOOP mesh, a titanized polypropylene lightweight mesh. Methods: From November 2017 to July 2019, 50 patients underwent surgery, who were with anterior vaginal prolapse stage Ⅲ-Ⅳ and (or) apical prolapse and posterior vaginal prolapse (stage Ⅰ-Ⅱ); 37 patients underwent self-cut TiLOOP mesh and 13 patients underwent pre-cut mesh-kit procedure. The subjective and objective parameters (including surgical success) of them were evaluated. Results: The mean follow-up time was (18±6) months. The overall surgical success rate was 90% (45/50). Prolapse recurrence rates were isolated anterior 2% (1/50), isolated apical 2% (1/50) and isolated posterior 6% (3/50). None of recurrent patients underwent re-treatment, including either surgery or use of a pessary at last follow-up. According to patient global impression of improvement (PGI-I), 46 patients (92%, 46/50) were very much better, and 4 patients (8%, 4/50) were much better. After the operation, pelvic floor distress inventory-short form 20 (PFDI-20) and pelvic floor impact questionnaire-short form 7 (PFIQ-7) scores were significantly lower than those before operation (all P<0.05); pelvic organ prolapse-urinary incontinence sexual questionnaire 12 (PISQ-12) score was no significant difference before and after operation (P>0.05), but without dyspareunia. The vaginal mesh erosion rate was 12% (6/50) and the stress urinary incontinence was observed in 2 cases (4%, 2/47). Conclusion: Transvaginal pelvic floor reconstruction with TiLOOP mesh is a safe and effective surgery, short-term efficacy is acceptable, how to reduce the mesh erosion still need to be explored.

RESUMO

PURPOSE: Develop a 3D model for the simulation of laparoscopic inguinal hernioplasty transabdominal preperitoneal (TAPP). METHODS: This is an experimental study, 18 participants were selected, divided into three groups, experimental (GE) surgeons in training, control (GC) experienced surgeons and Shaw (GS) nonexperienced surgeons. The simulation in the 3D model was carried out in 6 sessions fulfilling the 5 stages. Opening the peritoneum with the creation of the preperitoneal space; identification of important structures; hernia identification and reduction; placement and fixation of the mesh in Cooper's ligament and closure of the peritoneum. RESULTS: In the 1st stage, the GE obtained an average of 1.25 ± 0.42 in the 1st session and 3.25 ± 0.62 in the 6th session (p = 0.05) and in the 5th stage 0.91 ± 0.29 in the first session. 1st session and 1.91 ± 0.29 in the 6th session (p = 0.001), with no significant difference between groups. The learning and skill curve in the SG represented 1.08 ± 0.29 1st and 3.50 ± 0.90 6th session (p = 0.001). CONCLUSIONS: The creation of a systematization of training in simulation applied to the three-dimensional model enabled gain in laparoscopic skills and underpinned its theoretical and practical foundations.

RESUMO

A 76-year-old man was referred to our clinic after a foreign body seen in his sigmoid colon during a colonoscopy. He had undergone three operations for a left inguinal hernia within the previous 8 years, and the first procedure was a laparoscopic totally extraperitoneal approach. Four years later, removal of migrated and infected mesh was conducted by open approach. He then had a positive stool occult blood test for routine check-up 4 years after the remnant mesh removal. An ill-defined lesion was identified on colonoscopy. CT revealed a 2.7 cm diameter enhancing lesion in the sigmoid colon. Laparoscopic sigmoidectomy was performed, and remnant mesh fragment was found in the sigmoid colon and removed. The migrated mesh could not be wholly removed by open abdominal approach and the remnant mesh fragment migrated to sigmoid colon. It suggests the importance of a laparoscopic approach to remove the entire mesh.

RESUMO

An adequate integration of the prosthetic materials used to repair abdominal wall defects is necessary for satisfactory outcomes. We aimed to evaluate, in an animal model, the biological behavior of meshes used for abdominal wall surgery. Four groups of 10 rats were separated. After laparotomy, intraperitoneal prostheses were placed: 1) Prolene® (polypropylene microporous, heavy-weight), 2) Ultrapro® (polypropylene + poliglecaprone, macroporous low-weight), 3) Proceed® (polypropylene + polidoxanone + regenerated oxidized cellulose, microporous medium-weight), 4) Physiomesh® (polypropylene + poliglecaprone, macroporous lowweight). Macroscopic and microscopic analyses were performed at 30 days. The results were evaluated by two independent observers and expressed in means with standard deviation. For statistical analysis p < 0.05 was considered significant. On macroscopic examination, mesh integration was greater than 75% in all cases. Microscopic analysis showed greater global inflammation and more multinucleated giant cells in Prolene® (p < 0.01). Less inflammatory cells were observed at the muscle-mesh interface in Physiomesh® vs. Ultrapro® (p < 0.05). Collagen fibers disposition was similar in all meshes, although, microporous meshes had higher collagen deposit in the interfilamentous spaces (p < 0.01). In conclusion, in our animal model, microporous and heavy-weight polypropylene meshes produce greater inflammatory and foreign body reaction. Thus, composite meshes would have greater biocompatibility and better tolerance by the host.

RESUMO

OBJECTIVE: To evaluate the results of using titanium thread mesh implants in the treatment of anterior abdominal wall hernias. MATERIAL AND METHODS: This article evaluates the titanium thread mesh implant used by us in the treatment of 240 patients with anterior abdominal wall hernias; describes the features of this type of implants and the technical features of various types of operations using them. RESULTS: The overall rate of postoperative complications was 2.9%. Hernia recurrence was observed in 2.4% of patients after laparoscopic transabdominal preperitoneal hernioplasty. CONCLUSIONS: The use of a mesh implant made of titanium thread did not reveal any specific complications for this implant. At the stage of gaining experience with a mesh implant made of titanium thread, technical difficulties may occur when placing and fixing it, which increases the duration of surgery.

RESUMO

BACKGROUND: Precise visualization of meshes and their position would greatly aid in mesh shrinkage evaluation, hernia recurrence risk assessment, and the preoperative planning of salvage repair. Lightweight (LW) meshes are able to preserve abdominal wall compliance by generating less post-implantation fibrosis and rigidity. However, conventional 3D imaging techniques such as computed tomography (CT) and magnetic resonance imaging (MRI) cannot visualize the LW meshes. Patients sometimes have to undergo a second-look operation for visualizing the mesh implants. The goal of this work is to investigate the potential advantages of Automated 3D breast ultrasound (ABUS) pore texture analysis for implanted LW hernia mesh identification. METHODS: In vitro, the appearances of four different flat meshes in both ABUS and 2D hand-held ultrasound (HHUS) images were evaluated and compared. In vivo, pore texture patterns of 87 hernia regions were analyzed both in ABUS images and their corresponding HHUS images. RESULTS: In vitro studies, the imaging results of ABUS for implanted LW meshes are much more visualized and effective in comparison to HHUS. In vivo, the inter-class distance of 40 texture features was calculated. The texture features of 2D sectional plans (axial and sagittal plane) have no significant contribution to implanted LW mesh identification. Significant contribution was observed in coronal plane. However, since the mesh may have spatial variation such as shrinkage after implantation surgery, the inter-class distance of 3D coronal plane pore texture features are bigger than 2D coronal plane, so the contribution of 3D coronal plane pore texture features are more valuable than 2D coronal plane for implanted LW mesh identification. The use of 3D pore texture features significantly improved the robustness of the identification method in distinguishing between LW mesh and fascia. CONCLUSIONS: An innovative new ABUS provides additional pore texture visualization, by separating the LW mesh from the fascia tissues. Therefore, ABUS has the potential to provides more accurate features to characterize pore texture patterns, and ultimately provide more accurate measures for implanted LW mesh identification.

RESUMO

OBJECTIVE: The aim of this study was to evaluate which mesh type yields lower recurrence and complication rates after ventral hernia repair. SUMMARY BACKGROUND DATA: More than 400,000 ventral hernia repairs are performed annually in the United States. Although the most effective method for repairing ventral hernias involves using mesh, whether to use biologic mesh versus synthetic mesh is controversial. METHODS: Single-blind, randomized, controlled, pragmatic clinical trial conducted from March 2014 through October 2018; 165 patients enrolled with an average follow up of 26 months. Patients were randomized 1:1 to have their ventral hernias repaired using either a biologic (porcine) or synthetic (polypropylene) mesh. The primary study outcome measure was hernia recurrence at 2 years. RESULTS: A total of 165 patients (68 men), mean age 55 years, were included in the study with a mean follow-up of 26 months. An intention-to-treat analysis noted that hernias recurred in 25 patients (39.7%) assigned to biologic mesh and in 14 patients (21.9%) assigned to synthetic mesh (P = 0.035) at 2 years. Subgroup analysis identified an increased rate of hernia recurrence in the biologic versus the synthetic mesh group under contaminated wound conditions (50.0% vs 5.9%; P for interaction = 0.041). Postoperative complication rates were similar for the 2 mesh types. CONCLUSIONS: The risk of hernia recurrence was significantly higher for patients undergoing ventral hernia repair with biologic mesh compared to synthetic mesh, with similar rates of postoperative complications. These data indicate that the use of synthetic mesh over biologic mesh to repair ventral hernias is effective and can be endorsed, including under contaminated wound conditions.

RESUMO

BACKGROUND: For recurrent incarcerated and strangulated hernias, the optimal treatment strategy for each case is needed. CASE PRESENTATION: The study patient was a 70-year-old man. TAPP repair was performed for a left inguinal hernia (JHS Classification II-1) 7 years earlier. The patient experienced transient pain and swelling of the left inguinal region for 5 months and visited our emergency department for abdominal pain and vomiting. A CT scan showed a recurrent left inguinal hernia and small bowel incarceration, and emergency surgery was performed. Laparoscopic observation of the abdominal cavity revealed recurrent left inguinal hernia (Rec II-1) with small bowel incarceration. The small bowel was reduced after pneumoperitoneum, and no findings suggested intestinal tract necrosis. Adhesions around the herniated sac were dissected using an extraperitoneal approach and then shifted to mesh plug repair. No perioperative complications or hernia recurrence were observed in the 10 months after the surgery. CONCLUSIONS: This report describes a novel, successful surgical treatment for a recurrent incarcerated hernia. In our patient, we could easily perform dissection and understand the positional relationship by hybrid surgery using the TEP method. Additionally, in patients with incarcerated hernias, we believe that performing hybrid surgery by combining the TEP method would be useful because bowel dilation caused by intestinal obstruction would not disturb the operative field.
