Single-incision laparoscopic transabdominal preperitoneal repair in the treatment of adult female patients with inguinal hernia

BACKGROUND Women have a 3%lifetime chance of developing an inguinal hernia,which is not as common in men.Due to its cosmetic benefits,single-incision laparoscopic transabdominal preperitoneal(SIL-TAPP)inguinal hernia repair is becoming in-creasingly popular in the management of inguinal hernia in women.However,there are no studies comparing the safety and applicability of SIL-TAPP repair with conventional laparoscopic transabdominal preperitoneal(CL-TAPP)inguinal hernia repair for the treatment of inguinal hernia in women.AIM To compare the outcomes of SIL-TAPP and CL-TAPP repair in adult female patients with inguinal hernia and to estimate the safety and applicability of SIL-TAPP repair in adult female inguinal hernia patients.METHODS We retrospectively compared the clinical information and follow-up data of fe-male inguinal hernia patients who underwent SIL-TAPP inguinal hernia repair and those who underwent CL-TAPP inguinal hernia repair at the Affiliated Hos-pital of Nantong University from February 2018 to December 2020 and assessed the long-term and short-term outcomes of both cohorts.RESULTS This study included 123 patients,with 71 undergoing SIL-TAPP repair and 52 un-dergoing CL-TAPP repair.The two cohorts of patients and inguinal hernia charac-teristics were similar,with no statistically meaningful difference.The rate of intraoperative inferior epigastric vessel injury was lower in patients in the SIL-TAPP cohort(0,0%)than in patients in the CL-TAPP cohort(4,7.7%)and was significantly different(P<0.05).In addition,the median[interquartile range(IQR)]total hospitalization costs were significantly lower in patients in the SIL-TAPP cohort[$3287(3218-3325)]than in patients in the CL-TAPP cohort[$3511(3491-3599)].Postoperatively,the occurrence rate of trocar site hernia was lower in the SIL-TAPP cohort(0,0%)than in the CL-TAPP cohort(4,7.7%),and the median(IQR)cosmetic score was significantly higher in the SIL-TAPP cohort[10(10-10)]than in the CL-TAPP cohort[9(9-10)].CONCLUSION SIL-TAPP repair did not increase the incidence of intraoperative and postoperative complications in female in-guinal hernia patients.Moreover,female inguinal hernia patients who underwent SIL-TAPP repair had a lower probability of trocar site hernia and inferior epigastric vessel injury than female inguinal hernia patients who un-derwent CL-TAPP repair.In addition,female inguinal hernia patients who underwent SIL-TAPP repair reported a more aesthetically pleasing postoperative abdominal incision.Therefore,SIL-TAPP repair is a better option for the treatment of inguinal hernias in women.

Repair of the portal vein using a hepatic ligamentum teres patch for laparoscopic pancreatoduodenectomy: A case report

BACKGROUND Laparoscopic pancreatoduodenectomy (LPD) has been developed gradually with the advances in surgical laparoscopic techniques. It is technically challenging to perform LPD with portal vein resection and reconstruction. CASE SUMMARY A 71-year-old female patient was diagnosed with distal cholangiocarcinoma. After preoperative examination and rigorous preoperative preparation, the patient underwent LPD using 3D laparoscopy on July 17, 2018. During the surgery, we found that the tumor invaded the right wall of the portal vein;thus, pancreaticoduodenectomy combined with partial portal vein wall resection was performed. The defect of the portal vein wall was approximately 2.5 cm × 1.0 cm. The hepatic ligamentum teres was excised by laparoscopy and then recanalized in vitro. Following recanalization, the hepatic ligamentum teres was cut longitudinally and then trimmed into vascular patches that were then used to reconstruct the defect of the portal vein through 3D laparoscopy. The operative time was 560 min, and intraoperative blood loss was 100 mL. The duration of the blood occlusion time was 63 min. No blood transfusion was required. The patient underwent enhanced recovery after surgery procedures after the operation. The patient was discharged on postoperative day 11. Follow-up for 6 months after discharge showed no stenosis of the portal vein and good patency of blood flow. CONCLUSION It is safe and feasible to use the hepatic ligamentum teres patch to repair portal vein in LPD. However, the long-term patency of this technique for venous reconstruction requires further investigation.

Left abdominal wall proliferative myositis resection and patch repair:A case report

BACKGROUND Proliferative myositis is a rare benign tumor that is typically self-limiting and does not become malignant.It can be cured by simple resection without reported recurrence.Due to its rapid growth,hard structure and ill-defined borders,it can however be mistaken for malignant tumors such as sarcomas.CASE SUMMARY We investigate the case of a 64-year-old male with proliferative myositis of the abdominal wall,who was preoperatively administered a needle aspiration biopsy and given a simple excision and patch repair.We then compared it with other similar cases to determine the effectiveness of this treatment method.CONCLUSION Resection with follow-up observation has shown to be an effective treatment method for proliferative myositis.To avoid unnecessarily extended or destructive resection,a thorough and conclusive diagnosis is crucial,which requires adequate imaging and pathological knowledge.

Single Incision Laparoscopic Transabdominal Preperitoneal Repair for Strangulated Groin Hernia

Introduction: Single incision laparoscopic surgery (SILS) has become more popular for various surgical procedures including hernia surgery. Initial results of SILS in elective hernia repair were comparable to those of conventional laparoscopic approaches. However the use of SILS in emergency case has not been widely reported. This study aimed to evaluate the feasibility of the use of single incision laparoscopic transabdominal preperitoneal (TAPP) repair for patients presenting with strangulated groin hernia. Method: Emergency single incision laparoscopic TAPP repair were performed in our unit from June 2011 onwards for selected patients. Retrospectively data including the patient demographics, operative time, type of hernia, hospital stay, complications and recurrence rate were collected and analyzed. Result: There were a total of five patients in this series from June 2011 to June 2012. The median age was 62 years old with a male to female ratio of 4:1. Four patients had unilateral hernia (one femoral and three inguinal hernias) and one had bilateral hernia (unilaterally strangulated femoral hernia and bilaterally reducible indirect inguinal hernia). The median operative time was 75 minutes for patients with unilateral repair. None of the patients required bowel resection. The conversion rate to either conventional laparoscopic or open repair was zero. The median hospital stay was 2 days. No major complication or recurrence was detected. Conclusion: This series showed that single port laparoscopic TAPP repair for strangulated groin hernia is a feasible option with no major complication reported.

Debonding Patch Detection in FRP-Strengthened Materials with Fiber-Optic Interferometer

The interfacial debonding in fiber-reinforced plastic(FRP)strengthened repair material will affect the bonding strength and lead to failure of the repair without warning.Unfortunately the interfacial damage is normally invisible and often in the form of a patch rather than a through-width crack.Therefore,a debonding patch detection technique based on fiber optic interferometry is proposed.A quasi-impulse loading is applied with a rubberhead hammer and the total elongation of a surface-mounted optical fiber along the length of the repair material is measured as a function of load position.When a debonding patch is present,the induced sudden slope or sign change on the plot of fiber integral strain v.s.load position will reveal the extent and the location of the debonded area.The results of the study indicate that the proposed technique is applicable for debonding patch detection in repaired members under various support conditions.

EVOLUTION OF THE BLOOD INTERFACE USING AN AUTOLOGOUS VENOUS PATCH TO CORRECT AN AORTIC DEFECT IN RATS

In order to investigate the evolution of the venous patch blood inter face after implantation, an experimental model utilizing an autologous venous patch to repair an infrarenal abdominal aortic defect in rats was developed. A small piece of both the jugular vein and the aorta were first excised. After implantation and reestablishment of blood flow, the animals were subsequently sacrificed in groups of 3 at the following intervals: 10 seconds, 1, 10, 30 minutes, 1, 6, 12, 24 hours, 7, 30 and 90 days. All the patches and adjacent aortae were collected and studied using scanning electron microscopy. The results of our present show that: 1) the extensive endothelial lesion of both the autologous vein patch and the adjacent aorta is presented before implantation due to operative manipulation; 2) after blood flow reestablishment, the patch and the adjacent aortic interface are reactive to platelets and other blood cells; 3) the new cellular lining begins to appear from the 7th day after implantation, but it is not complete at 3 months; 4)from the model, the endothelial repair of autologous venous patch and its adjacent aorta is a very slow process.

Dual human iPSC-derived cardiac lineage cell-seeding extracellular matrix patches promote regeneration and long-term repair of infarcted hearts

Human pluripotent stem cell-derived cardiovascular progenitor cells (hCVPCs) and cardiomyocytes (hCMs) possess therapeutic potential for infarcted hearts;however, their efficacy needs to be enhanced. Here we tested the hypotheses that the combination of decellularized porcine small intestinal submucosal extracellular matrix (SIS-ECM) with hCVPCs, hCMs, or dual of them (Mix, 1:1) could provide better therapeutic effects than the SIS alone, and dual hCVPCs with hCMs would exert synergic effects in cardiac repair. The data showed that the SIS patch well supported the growth of hCVPCs and hCMs. Epicardially implanted SIS-hCVPC, SIS-hCM, or SIS-Mix patches at 7-day post-myocardial infarction significantly ameliorated functional worsening, ventricular dilation and scar formation at 28- and 90-day post-implantation in C57/B6 mice, whereas the SIS only mildly improved function at 90-day post-implantation. Moreover, the SIS and SIS-cell patches improved vascularization and suppressed MI-induced cardiomyocyte hypertrophy and expression of Col1 and Col3, but only the SIS-hCM and the SIS-Mix patches increased the ratio of collagen III/I fibers in the infarcted hearts. Further, the SIS-cell patches stimulated cardiomyocyte proliferation via paracrine action. Notably, the SIS-Mix had better improvements in cardiac function and structure, engraftments, and cardiomyocyte proliferation. Proteomic analysis showed distinct biological functions of exclusive proteins secreted from hCVPCs and hCMs, and more exclusive proteins secreted from co-cultivated hCVPCs and hCMs than mono-cells involving in various functional processes essential for infarct repair. These findings are the first to demonstrate the efficacy and mechanisms of mono- and dual-hCVPC- and hCM-seeding SIS-ECM for repair of infarcted hearts based on the side-by-side comparison.

Material parameter modeling and solution technique using birth–death element for notched metallic panel repaired with bonded composite patch

This paper seeks to outline a novel three-layer model and a new birth-dteath element solution technique to evaluate static strength of notched metallic panel repaired with bonded com- posite patch and to optimize material parameters. The higher order 3D, 8-node isotropic solid ele- ment and 8-node anisotropic layered solid element with three degrees of freedom per node are respectively implemented to model substrate panel, adhesive layer and composite patch to establish three-layer model of repaired panel. The new solving technique based on birth-death element is developed to allow solution of the stress pattern of repaired panel for identifying failure mode. The new model and its solution are used to model failure mode and residual strength of repaired panel, and the obtained results have a good agreement with the experimental findings. Finally, the influences of material parameter of adhesive layer and composite patch on the residual strength of repaired panel are investigated for optimizing material properties to meet operational and envi- ronmental constraints.

A New Alternative Technique for Preperitoneal Inguinal Hernia Repair: Using Groin Innominate Fascial Island Flap

Aim: Despite the fact that reported low recurrence rates and improvement results, optimal surgical technique for in-guinal hernia repair was not found and recurrence was not eliminated. We used firstly groin innominate fascial island flap to reinforce the weak inguinal tissue for the repair. Methods: From the February 2010 to December 2010, 15 patients (13 male and 2 female) with inguinal hernia underwent repair with using island groin innominate fascial flap. The follow-up period ranged from 8 to 12 months (mean, 10 months). Results: Seroma developed in one case. Others had not any complications. Conclusion: Because of our technique avoids from the complications and drawbacks of the prosthetic mesh, autograft and abdominal wall flaps, we think that the groin deep fascial flap can be a good alternative to prosthetic meshes for reconstruction of inguinal hernia repair.

Laparoscopic repair via the transabdominal preperitoneal procedure for bilateral lumbar hernia: Three cases report and review of literature

A lumbar hernia is a rare entity, and a bilateral lumbar hernia is much rarer. From May 2015 to October 2017, we treated only three patients with bilateral lumbar hernias. One patient came to the hospital presenting with right-sided abdominal pain, and the other two patients presented with bilateral lumbar masses. The previous bilateral lumbar hernia reported in the literature was repaired by open surgery. The laparoscopic approach via the transabdominal preperitoneal(TAPP) procedure with the self-gripping Parietex ProG rip? mesh was performed at our center. The laparoscopic repair was conducted by a skilled hernia surgeon, and was successfully performed in the three patients. The patients resumed a semiliquid diet and had no activity restriction after six hours following the operation. No antibiotics were used after the surgery. The operative times of the three patients were 120 min, 85 min, and 130 min. The blood loss volumes of the three patients were 20 mL, 5 mL, and 5 mL. The visual analogue scale pain scores of the three patients were 1, 2, and 2 on postoperative day 1, and were 1, 2, and 1 on postoperative day 3. No perioperative complications, such as bulge, wound infection and hematoma, occurred after the surgery. All of the patients were discharged on the third day after the operation. There was no chronic pain and no hernia recurrence during the follow-up. This study showed that the laparoscopic TAPP approach with the self-gripping mesh is safe and feasible, and can be considered an alternative method for the treatment of bilateral lumbar hernias.

Application of a finite element method to stress distribution in buried patch repaired polyethylene gas pipes

Advantages of polyethylene pipes over traditional steel or metal pipes have increased industry interest in the use of polyethylene(PE)pipelines for underground applications and especially in gas distribution networks.In this study,finite element analysis is used to calculate the stress distribution in a patch repaired defective gas pipe under internal pressure.The pipe is assumed to be buried at a depth of 125 cm.The material is assumed to be medium density PE80B,where the patch material was selected from high density polyethylene(HDPE).During the loading process,the seasonal pipe temperature changes,surcharge loads,soil column weight,and soil-pipe interaction were included in the analysis.Four types of patch arrangements were selected to repair the damaged pipe.The shape of the defect hole was deemed as circular or elliptic.With respect to elliptic defects,various minor to major diameter ratios,a/b,were selected to simulate a circular to a crack shaped defect.Based on the results,the semi-circular and saddle fusion patches decrease the peak von Mises stress in the pipe by almost the same amount.However,the minimum peak von Mises stress in the patch corresponds to the saddle fusion repair arrangement.Based on the results,with respect to a saddle fusion repair,when the shape of the defect approaches a crack,the peak von Mises stress in the pipe almost doubles and exceeds the pipe allowable stress for a working life of 50 years.With respect to higher values of a/b,the stress level in the patch repaired pipe is significantly below its limiting value for the same life expectancy.

疝修复补片:材料设计与应用的最新进展

背景:与传统的缝合方式相比,采用补片修复腹壁缺陷的无张力疝修补手术能有效减少术后疼痛和疝气复发率,已经成为近年来治疗腹疝的首选方法。目的:归纳总结不同疝修复补片在应用过程中的优缺点。方法:以“腹壁缺损,疝气补片,疝气治疗”为中文检索词,以“abdominal wall defect,hernia patches,hernia treatment”为英文检索词,分别检索中国知网、谷歌学术和PubMed数据库,检索时限主要为2018年1月至2024年2月,同时采用少数经典的早期文献以概述疝修复补片的发展历程,通过阅读题目和摘要进行初步筛选,排除与疝修复材料相关性较低的文献,最终纳入90篇文献进行归纳总结。结果与结论:根据制备材料的不同可以将疝修复补片分为不可吸收人工合成补片、可吸收人工合成补片、天然高分子补片和复合补片。不可吸收补片具有较高的机械强度,有益于疝气区域的组织愈合,但体内长期存在的补片可能会引发身体的免疫反应,导致炎症和疼痛。可吸收人工合成补片与天然高分子补片具有良好的组织相容性、降解性,但机械强度不稳定。复合材料补片继承了传统不可吸收补片优良的机械性能,同时通过可吸收部分的设计降低了一些并发症发生的风险。在疝修复补片的后续研究中,科研人员应重点关注如何将新技术与复合补片结合起来,形成多功能的疝修复补片。

面向边缘部署场景的轻量神经网络修复算法

随着深度学习技术的不断进步,神经网络在各领域得到广泛应用,特别是在边缘计算环境中,例如智能交通和新型电网等典型场景.然而,神经网络的可靠性问题限制了其在真实世界的广泛应用.在复杂的边缘环境中,预训练模型往往因未涵盖所有可能的边缘情况而性能下降.因此,针对部署中的神经网络进行高效修复成为一个关键的研究课题.传统修复方法通常涉及整个模型的重新训练,这在边缘场景中具有诸多局限性.首先,不同地理区域的设备可能面临独特的自然噪声,使得统一模型难以适应所有环境.其次,深度神经网络的大规模参数使得其训练和部署时资源消耗巨大,且更新期间的服务中断将降低系统的可用性.为解决这些问题,本文提出了一种轻量级的补丁式神经网络修复算法.该算法通过引入个性化的补丁来增强神经网络对不同边缘环境中自然噪声和边角案例的鲁棒性.具体的,在故障定位阶段,类比于程序插桩中通过注入代码以检测、改进和分析软件行为,本文提出了神经网络插桩技术.通过将模型探针插桩进神经网络,观测其内部运行情况,实现了对错误样本的故障定位.在故障修复时,通过插入无监督搜索得到的神经网络补丁来纠正原始神经网络的输出.此外,本文提出了故障预测模块以提前预测潜在的错误输出,从而仅在必要时激活补丁.在基于2个数据集、15种噪声以及4个神经网络模型的实验中,与现有修复算法相比,本文方法在修复性能上取得了 6.64%至20.00%的提升.同时,本文方法所需的训练样本量减少了超过90%,而所需更新的参数量最高减少了 91.94%.这种有效且轻量的特性为解决边缘计算环境中神经网络的可靠性问题提供了有效途径.
