Urogenital Complications of Groin Hernia Surgery: A Multicentre Study in Guinea

Context and Objective: Groin hernia is a common pathology in visceral surgery (2nd rank after appendicitis), which affects approximately 4.6% of the African population. Restoring the normal anatomy of the groin region is one of the most benign interventions. However, uro-andrological complications are possible. This study aimed to contribute to the improvement of the management of urogenital complications of groin hernia surgery. Patients and Method: We carried out a prospective study of descriptive type with a duration of 6 months from 1 August 2021 to 31 January 2022. The data were collected using a pre-established survey sheet. The study covered several sites (public hospitals and private clinics) in Guinea. Results: The urogenital complications of the surgery of the hernia of the groin represented 15.22% or 14 cases out of 92 patients. The average age was 37.00 years with extremes of 20-69 years. Polygamists occupied the first place. The reason for consultation was dominated by decreased testicular volume (42.86%), followed by a desire to conceive (21.43%). Unilateral testicular atrophy represented 63.64%, bilateral 27.27%. We performed a left orchidectomy in one patient and a cystorraphy in another simple operative follow-up. The other cases consisting of testicular atrophy, due to lack of a suitable technical platform, did not benefit from any specific therapeutic treatment. Conclusion: Urogenital complications of groin hernia surgery are relatively common. Testicular atrophy was the main clinical complication. The left orchidectomy and cystorraphy were the therapeutic procedures performed.

Comparison of Flow Characteristics Around Refractive and Right-angled Groins in Barotropic and Baroclinic Conditions

Groins are employed to prevent nearshore areas from erosion and to control the direction of flow. However, the groin structure and its associated flow characteristics are the main causes of local erosion. In this study, we investigate the flow patterns around refractive and right-angle groins. In particular, we analytically compare the flow characteristics around a refractive groin and study the degree of accuracy that can be achieved by using a right-angle groin of various projected lengths. To compare the flow characteristics, we replaced the right-angle groin with an approximation of a refractive groin. This replacement had the least effect on the maximum velocity of flow in the channel. Moreover, we investigated the distribution of the density variables of temperature and salinity, and their effects on the flow characteristics around the right-angle groin. A comparison of the flow analysis results in baroclinic and barotropic conditions reveals that the flow characteristic values are very similar for both the refractive and right-angle groins. The geometry of the groin, i.e., right-angle or refractive, has little effect on the maximum speed to relative average speed. Apart from the angular separation, the arm length of the groin in downstream refractive groins has less effect on other flow characteristics than do upstream refractive groins. We also correlated a number of non-dimensional variables with respect to various flow characteristics and groin geometry. These comparisons indicate that the correlation between the thalweg height and width of the channel and groin arm＇s length to projection length have been approximated using linear and nonlinear formulas regardless of inner velocity in the subcritical flow.

Analysis of Soil arching effect for Blind sheet-pile wharf based on ABAQUS

Combined with practical engineering, based on the introduction of soil arching theory, we explore the impact of barrier piles in blind sheet-pile bank connecting structure. Besides, we build a plane strain model by ABAQUS sot＇cware to study the impact of cross section type, the pile spacing and soil properties on soil arching effect. We find that cross section type of the pile has a certain influence on soil stress distribution in front of the barrier piles by comparing circular cross section and rectangular cross section. We also find that clear distance between the barrier piles and cohesive force of the soil have a great influence on that impact. We can increase clear distance between the barrier piles appropriately to improve the efficiency of construction and reduce the proiect cost.

钱塘江河口盐官段混合式丁坝修建对水沙及河床影响的实测研究

钱塘江北岸古海塘堤脚加固工程中,辅助围堰施工的临时性管袋黏土混合式丁坝对工程的顺利进行、提高施工效率起着至关重要的作用,然而目前对其周围水沙运动的研究较少,且缺乏相关实测资料。考虑混合式丁坝修建的动态过程,利用无人机拍摄水流视频结合LSPIV(粒子图像测速)处理技术对丁坝修建前、中、后期周围的流场进行分析,并对丁坝附近的地形进行跟踪测量,同时对不同潮差的水流含沙量进行现场测定。结果表明,丁坝具有改变水流方向,减少水流对河岸冲刷的作用,且丁坝越长,挑流作用越明显,为围堰施工提供了较为平缓的水流条件;混合式丁坝对坝后处的促淤效果明显,且坝后地形变化与含沙量密切相关,潮差越大,水体含沙量越高,丁坝后河床淤积幅度越大,有利于提高围堰的施工效率。研究成果对之后相关物理模型和数值模拟的研究提供数据支持。

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.

Reliability of the K-Force Muscle Controller Dynamometer on Eccentric and Isometric Hip Adduction Strength

Hip adduction strength tests are commonly used in clinical practice to provide an accurate diagnosis of groin injuries. Athletes with reduced adductor muscle strength are at risk of developing groin injuries. Our study aimed to evaluate the relative and absolute test-retest reliability of the side-lying eccentric hip adduction strength test and the long-lever adduction squeeze test using the K-Force hand-held dynamometer. Twenty physically active male individuals with a mean age (±SD) of 30.7 (±7.3) years were included. Both tests presented excellent test-retest reliability (Intraclass Correlation Coefficient: 0.77 - 0.95). The best and mean scores of the eccentric and isometric tests presented the smallest test-retest variation (MDC%: 12.8 - 14.9 and MDC%: 14.6 - 18.7, respectively). Our study showed that the K-Force dynamometer has excellent reliability for assessing hip adduction strength in two different testing positions. We suggest the best and mean of three repetitions for clinical practice as they present the lowest variability. Further research evaluating its clinimetric properties in different populations and gender is recommended.

U型弯道内L型丁坝群对不同水位水流水力特性影响试验研究

弯道影响通航的同时,易造成水土流失、河床淤积等现象。L型丁坝群是一种常用的水利工程结构,能调整水流速度、改善水流动力学特性,用于保护河岸线、防止淤积。我国多数河流常年无固定水位,布置丁坝群后,不同水位下,丁坝群对水流特性的影响情况值得研究。为此,通过试验,使用粒子图像测速系统和无线水位测量系统,分别对水流流速和水位等物理量进行测量、记录,并通过Matlab软件分析了不同水位下丁坝群对水流的影响情况,得出如下结论:随着水位的增加,水流速度逐渐减小,丁坝群下游部分是防冲刷和淤积的最佳位置,且坝高水深比影响丁坝作用的发挥,当比值为2.5左右时,可使丁坝群的作用得到良好发挥,在工程设计中可予以考虑。

Current trends in laparoscopic groin hernia repair: A review

Hernia is a common problem of the modern world with its incidence more in developing countries. Inguinal hernia is the most common groin hernia repaired worldwide. With advancement in technology operative techniques of repair have also evolved. A Pub Med and COCHRANE database search was accomplished in this regard to establish the current status of laparoscopic inguinal hernia repair in view of recent published literature. Published literature support that laparoscopic hernia repair is best suited for recurrent and bilateral inguinal hernia although it may be offered for primary inguinal hernia if expertise is available.

Current trends in the diagnosis and management of post-herniorraphy chronic groin pain

Inguinodynia(chronic groin pain) is one of the recognised complications of the commonly performed Lichtenstein mesh inguinal hernia repair.This has major impact on quality of life in a significant proportion of patients.The pain is classif ied as neuropathic and nonneuropathic related to nerve damage and to the mesh,respectively.Correct diagnosis of this problem is relatively difficult.A thorough history and clinical examination are essential,as is a good knowledge of the groin nerve distribution.In spite of the common nature of the problem,the literature evidence is limited.In this paper we discuss the diagnostic tools and treatment options,both non-surgical and surgical.In addition,we discuss the criteria for surgical intervention and its optimal timing.

Fascinating history of groin hernias:Comprehensive recognition of anatomy,classic considerations for herniorrhaphy,and current controversies in hernioplasty

Groin hernias include indirect inguinal,direct inguinal,femoral,obturator,and supravesical hernias.Here,we summarize historical turning points,anatomical recognition and surgical repairs.Groin hernias have a fascinating history in the fields of anatomy and surgery.The concept of tension-free repair is generally accepted among clinicians.Surgical repair with mesh is categorized as hernioplasty,while classic repair without mesh is considered herniorrhaphy.Although various surgical approaches have been developed,the surgical technique should be carefully chosen for each patient.Regarding as interesting history,crucial anatomy and important surgeries in the field of groin hernia,we here summarized them in detail,respectively.Points of debate are also reviewed;important points are shown using illustrations and schemas.We hope this systematic review is surgical guide for general surgeons including residents.Both a skillful technique and anatomical knowledge are indispensable for successful hernia surgery in the groin.

A Case of Local Groin Abscess Caused by Transfemoral Coronary Procedures

Bacterial infection due to coronary angiography is an uncommon but important complication of percutaneous coronary intervention (PCI) which is responsible for significant morbidity and extended hospital stay. The reasons for this symptom are still unclear. We report a case of local groin abscess two weeks after the latest procedure. The reasons responsible for the groin abscess in this case might be diabetes mellitus without being properly controlled, left ventricular (LV) systolic dysfunction, multiple operations in the same site, the usage of vascular closure device (VCD), and long time pressure after the procedure. We should pay enough attention to these risk factors in the future clinical practice to avoid this serious complication.

The Groin Physiology Revisited

The purpose is to contribute new information to the existing body of knowledge of the physiology of the groin. In a prospective ultrasonographic study, after an informed consent, 10 men and 10 women who were intact in the groin areas of surgery or relevant disease were involved. For a comparison, additional groups of 5 men and 5 women with abdominal wall hernias, but with no groin hernias, and other 5 men with inguinal hernias were included. The distal descent of the internal oblique muscle during the Valsalva’s manoeuvre in men was 0.8 cm ± 0.1 and in women it was 0.3 cm ± 0.1 (p < 0.001);the plate of transversus abdominis muscle changed its initial configurations and took on the characteristics of aponeurosis. During the Valsalva manoeuvre the rectus abdominis muscle demonstrated a distal latero-caudal shift of its lateral margin. In individuals with failed mechanics of the abdominal wall, the rectus abdominus does not realize the protective function. The mobile anatomic structures in the groin are oriented in three frontal planes. It formulated the concept of a synchronous protective function of all myofascial structures in the groin. We established that the anatomic structures transform the inguinal canal into a hermetic entity, which protects both the ingunal canal and the spermatic cord.

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.

Acute appendicitis presenting with abdominal wall and right groin abscess:A case report

We report a case of right lower abdominal wall and groin abscess resulting from acute appendicitis. The patient was an 27-year-old man who had no apparent abdominal signs and was brought to the hospital due to progressive painful swelling of right lower abdomen and the groin for 10 d. Significant inflammatory changes of soft tissue involving the right lower trunk were noted without any apparent signs of peritonitis. Laboratory results revealed leukocytosis. Abdominal ultrasonography described the presence of abscess at right inguinal site also communicating with the intraabdominal region. Right inguinal exploration and laparotomy were performed and about 250 mL of pus was drained from the subcutaneous tissue and preperitoneal space. No collection of pus was found intraabdominally and subserous acute appendicitis was the cause of the abscess. The patient fully recovered at the end of the second post-operation week. This case reminds us that acute appendicitis may have an atypical clinical presentation and should be treated carefully on an emergency basis to avoid serious complications.
