Clinical value of a novel biological mesh in laparoscopic inguinal hernia repair: a multicenter prospective randomized controlled study / 中华消化外科杂志

Objectives:To investigate the clinical value of a novel non-crosslinked biological mesh in laparoscopic inguinal hernia repair.Methods:The prospective randomized controlled study was conducted. The clinical data of 50 adult patients with unilateral inguinal hernia who were admitted to 3 medical centers, including Ruijin Hospital of Shanghai Jiaotong University School of Medicine et al, from September 2019 to March 2020 were selected. Based on random number table, patients were divided into two groups. Patients using the novel non-crosslinked biological mesh in repair surgery were divided into the experiment group and patients using the lightweight, micro-porous, partially absorbable synthetic mesh in repair surgery were divided into the control group. Observation indicators: (1) grouping situations of the enrolled patients; (2) endpoint of the study. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M(range), and comparison between groups was conducted using the non-parameter rank sum test. Count data were described as absolute numbers and (or) persentages, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Comparison of ordinal data was conducted using the non-parameter rank sum test. Repeated measurement data were analyzed using the repeated ANOVA. Taking the recurrence rate of hernia as the basis of efficacy evaluation, according to the intention-to-treat analysis, the confidence interval method (Newcombe Wilson method) was used to conduct non-inferiority statistical analysis of the recurrence rate of hernia between the experiment group and the control group. If the upper limit of 95% confidence interval of the difference of recurrence rate of hernia between the experiment group and the control group is less than 10%, the experiment group is considered to be non-inferior to the control group. Results:(1) Grouping situations of the enrolled patients. A total of 50 adult patients with inguinal hernia were selected for eligibility. There were 44 males and 6 females, aged (60±15)years. All 50 patients were randomly divided into to the experiment group and the control group with 25 cases each. One patient in the control group was not followed up at postoperative month 2, and the rest of 49 patients completed all expected follow-up. No patient in the two groups fell off or were removed. (2) Endpoint of the study. ① The primary endpoint of study. The recurrence rate of hernia was 0 in the experiment group, versus 4%(1/25) in the control group, respectively, showing no significant difference between the two groups ( P>0.05). Results of non-inferiority statistical analysis showed that the 95% confidence interval of the difference of recurrence rate of hernia between the two groups was -19.54% to 9.72%, with the upper limit as 9.72%, which was less than 10%. ② The secondary endpoint of study. There were 2 patients in the control group occurred seroma at postoperative day 14, and none of the rest of patient in the two groups occurred seroma during the follow-up, showing no significant difference in the occurrence of seroma between the two groups ( P>0.05). There was 1 patient in the control group feeling discomfort or foreign body sensation in groin area at postoperative month 2, and none of the rest of patient in the two groups feeling discomfort or foreign body sensation in groin area during the follow-up, showing no significant difference in the feeling discomfort or foreign body sensation in groin area between the two groups ( P>0.05). There was no patient occurred surgical site infection in the experiment group, and there was 1 patient in the control group occurred postoperative skin infection, which had no relationship with mesh. There was no patient in both two groups occurred fever, anaphylaxis and patch related serious adverse reaction during the follow-up. The resting visual analogue scale score, active visual analogue scale score of patients at postoperative 2 days and postoperative 18 months were 0.44±1.00, 1.28±1.46 and 0, 0 in the experiment group, versus 0.40±0.76, 1.28±1.14 and 0.24±1.20, 0.44±1.29 in the control group, respectively. There was a significant difference in the time effect of postoperative active visual analogue scale score of patients between the two groups ( Ftime=10.19, P<0.05). The thickness of the novel non-crosslinked biological mesh before implantation was 0.5?0.7 mm. Two months after operation, results of B-ultrasonic examination in groin area of 10 patients from the experiment group showed a strong echo area at the patch implant area with a thickness as 2 mm. Conclusion:Application of novel non-crosslinked biological mesh in laparoscopic inguinal hernia repair is safe and effective.

Study on influencing factors of seroma after laparoscopic preperitoneal tension-free inguinal hernia repair / 国际外科学杂志

Objective:To explore the influencing factors of seroma after transabdominal preperitoneal prosthetic (TAPP) inguinal hernia by laparoscopy.Methods:A retrospective cohort study was used to analyze the clinical data of 320 patients with inguinal hernia who received TAPP in Fuyang Fifth People′s Hospital from December 2019 to December 2022, including 226 males and 94 females, with an average age of (61.46±10.22) years (range: 23-76 years). Patients were divided into seroma group ( n=18) and non-seroma group ( n=302) according to whether seroma occurred after surgery. Multivariate Logistic analysis was used to screen the influencing factors of seroma after TAPP tension-free repair, and based on Softmax strategy, the artificial neural network model was constructed with binary classification variables survival 0 (no outcome event occurred) and 1 (outcome event occurred) as outcome variables. receiver operating characteristics (ROC) and cumulative gain graph were used to analyze the model differentiation and application value. The measurement data of normal distribution were expressed as mean±standard deviation ( ± s), and independent sample t-test was used for comparison between groups. Chi-square test was used for comparison between count data groups. Results:The incidence of postoperative seroma in 320 patients was 5.63% (18/320), including 7 cases of type Ⅰ, 4 cases of type Ⅱ, and 7 cases of type Ⅲ, all of which were improved after symptomatic treatment. Combined with underlying diseases, anticoagulant drugs, duration of disease, operation time, intraoperative blood loss, hernia sac diameter, mesh fixation method, neutrophil to lymphocyte ratio (NLR) were factors influencing seroma ofter TAPP in inguinal hernia patients ( OR=1.732, 2.414, 2.346, 1.480, 2.159, 1.725, 1.248, 2.179; 95% CI: 1.385-2.942, 1.764-3.176, 1.280-3.209, 1.263-2.275, 1.331-2.861, 1.308-2.239, 1.005-1.764, 1.644-2.982; P<0.05). The ROC curve and cumulative gain graph showed that the artificial neural network model could well predict the probability of postoperative seroma. Conclusions:The occurrence of seroma after TAPP tension-free repair in inguinal hernia patients is related to underlying diseases, taking anticoagulant drugs, course of disease, operation time, intraoperative blood loss, diameter of hernia sac, patch fixation method, NLR and many other factors. Clinical attention should be paid to these problems to reduce the incidence of postoperative seroma.

EFFECT OF THE COPENHAGEN PROTOCOL AND HOLMICH PROTOCOL FOR CHRONIC GROIN PAIN IN YOUNG ADULT FOOTBALL PLAYERS FOR IMPROVEMENT IN PAIN, STRENGTH AND PERFORMANCE - A COMPARATIVE STUDY

Background: Groin injuries often exhibit major problems, such as high rates of recurrence [3],prolonged durations of absence from sports [1], unclear prognosis [4], and its chronicity [4, 5]. This causes time loss and some of the biggest losses in the performances of the players. Thus it has been a challenge for physiotherapists as well as players who suffer from the injury. Only some advances in the exercise therapy has successfully reduced the time loss and provided significant improvement in the performances later on. Studies done by Holmich et al. and Haroy et al. have provided impressive results in treatment of the players suffering from chronic groin pain and overall reduction of adductor related groin injuries. Testing of this exercise therapy protocols on the parameters of the pain reduction, strength and performance improvement and comparing the results amongst each other is yet to be done on the quantitative and qualitative analysis. Aim: To study and compare the effects of the Holmich protocol and Copenhagen protocol in pain reduction strength improvement and performance improvement among young adult footballers with chronic groin pain. 61 footballers with the Method: chronic groin pain complaints were selected as study subjects. Total sample size was then divided into two groups by odd and even method to form two intervention groups for both the protocols (Group A and Group B). Prevalence was tested on the basis of VAS MMT and Hip and Groin Outcome Scale (HAGOS). These intervention groups performed adductor strengthening protocols during their warm up sessions or as a treatment when the players were unable to play for their respective teams. In our studies we have compared the results Results: of the pre interventional findings with post interventional results in two groups of football players (Group A and Group B). The data was then analyzed for inter-group and intra-group analysis and comparison was done statistically. The results from the studies showed 1) Copenhagen protocol was significantly better in terms of the reducing the pain in subjects. 2) Holmich protocol was significantly better in terms of improvement of the strength in subjects. 3) Copenhagen protocol was significantly better in improvement of the performance of the subjects. Conclusion: Both the adductor strengthening protocols have shown significant improvement in terms of treating the subjects but on the basis of pain reduction and performance improvement Copenhagen protocol showed better success rates. Whereas Holmich protocol has excelled in terms of strength improvement amongst the subjects.

Clinical application of free groin flap in repairing soft tissue defect in extremities / 中华显微外科杂志

Objective:To observe and summarise the clinical effect of free groin flap in repairing of soft tissue defects in extremities, and to explore the selection of main vessel in a flap.Methods:From January 2018 to January 2021, 146 patients with soft tissue defects in extremities were treated with free groin flaps in the Department of Hand and Microsurgery, Guangxi Guilin Xing'an Jieshou Orthopaedic Hospital. There were 126 patients with traumatic wound and 20 with chronic ulcer. In addition, 86 of the patients with bone fracture and exposure of internal fixator, 18 with tendon, nerve or artery injuries or defects. There were 6 patients with severe infection and other 3 with deep dead space. The sizes of wound ranged from 2.0 cm×3.0 cm to 25.0 cm×6.0 cm. The flap was the same size as the wound and not enlarged. Firstly, the superficial branch of superficial iliac circumflex artery was explored as the axial artery for all the flaps, then the blood supply vessels of the flap were selected according to the availability of the axial artery. The size, course, adjacent and possible length to be freed of the axial artery and the accompanying veins of a flap were recorded. The donor sites were directly sutured and closed. All patients were included in the postoperative follow-up at outpatient clinic.Results:Free groin flap were used to repair the wounds in all patients. However, the main blood supply vessel of the flap was not constant, and it was often required to adjust the way of flap harvesting. Superficial circumflex iliac artery was taken as the axial vessels in 141 patients (96.6%), among them, 133 cases(94.3%) had the superficial branch as the axis and 5 cases (3.6%) had deep branch as the axis. Three patients (2.1%) had the bone and soft tissue defects reconstructed with vascularised iliac mosaic osteocutaneous flap with superficial circumflex iliac artery as axial vessel and 5 cases(3.4%) had the superficial epigastric artery as axial vessel. The axial arteries were measured as follow: the superficial branch of the superficial circumflex iliac artery was 0.5-0.9 mm in diameter and 7.0-9.0 cm in length, the outer diameter of the deep branch was 1.2-1.4 mm and 9.0-11.0 cm in length, and the outer diameter of superficial epigastric artery was 1.0-1.6 mm and 8.0-11.3 cm in length. All the flaps survived smoothly after surgery and the follow-up period ranged 6-40 (mean 26) months. The texture of the flaps was soft with good function.Conclusion:Free groin flap can be used to repair soft tissue defects in extremities. The main axial vessel is the superficial branch of the superficial circumflex iliac artery, followed by the deep branch or the trunk. The superficial abdominal artery can also be used as an axial vessel. Under the circumstances, the flap design needs to be adjusted without changing the supply area

Inguinal hernia in southern Brazil - challenges in follow-up and recurrence rates / Hérnia inguinal no Sul do Brasil - desafios no seguimento e taxas de recorrência

ABSTRACT Introduction: recurrence rates for primary hernia repair range from 0.5 to 15 percent depending upon the hernia site, type of repair, and clinical circumstances. Many risk factors are known and they must be considered before the procedure. In developing countries, follow up and maintenance of databases are critical to understand the real numbers. Methods: a retrospective cohort study analyzed adult patients who have undergone inguinal hernia repair at Hospital de Clínicas de Porto Alegre, a tertiary care government public hospital, between 2013 and 2015. Medical records, telephone, and letter contact have been reviewed in order to complete the minimum period of 5 years of follow-up. The analyzed data focused on the surgeon's experience and the recurrence rate in 5 years of follow-up. Results: a total of 1094 medical records were selected and a complete five years follow-up were possible in 454 patients - 538 inguinal hernia repairs due to bilateral approach in 84 patients. These 454 patients answered, in a validated questionnaire about symptoms of recurrence. The total recurrence rate was 9.29%. For the patients who had Nyhus IV, recurrence rate was 24.1% against 9.9% after primary hernia repair, with a 2.4 higher risk. There was no difference in recurrence between surgeons and training surgeons. Conclusion: our data reveal an acceptable recurrence rate in a tertiary care hospital with residents, and to our knowledge is the first Brazilian report with long term follow up. An increased re-recurrent hernia was found when compared with primary hernia repair.

RESUMO Introdução: a recorrência da hérnia inguinal após hernioplastia varia de 0,5 a 15 por cento, dependendo do local da hérnia, tipo de reparo e circunstâncias clínicas. Muitos fatores de risco são conhecidos e devem ser considerados antes do procedimento. Acompanhamento e adequado bancos de dados são fundamentais para entender a incidência de recidiva. Métodos: estudo de coorte retrospectivo analisou hernioplastias inguinais realizados no Hospital de Clínicas de Porto Alegre entre 2013 e 2015. Para concluir 5 anos de seguimento, analisamos o prontuário e fizemos contato telefônico e por correio. Resultados: o total de 1094 registros médicos foram selecionados e um seguimento de pelo menos 5 anos foi possível em 454 pacientes - 538 reparos de hérnia inguinal devido à abordagem bilateral em 84 pacientes. Os pacientes responderam um questionário validado sobre sintomas de recorrência. A taxa total de recorrência foi de 9,29%. No grupo masculino, a recorrência foi de 10% contra 4% no grupo feminino. Para os pacientes com hérnia Nyhus IV, a recidiva foi de 24% contra 8% após o reparo da hérnia primária, com um risco de 2,8 maior. Não houve diferença na recorrência entre cirurgiões experientes e em treinamento. Conclusão: nossos dados revelam uma taxa de recorrência aceitável em um hospital de ensino, e para o nosso conhecimento é o primeiro artigo com acompanhamento de longo prazo no sul do Brasil. A re-recidiva da hérnia foi maior quando comparada com o reparo da hérnia primária.

En total 34 (22%) pacientes no salieron de alta el mismo día de la cirugía: Ocho (5,2%) pacientes por presentar complicaciones y 26 (16,8%) pacientes por razones administrativas/ sociales. Conclusión: La cirugía ambulatoria de HIU en adultos realizada por la técnica abierta o laparoscópica, es un procedimiento seguro que permite el alta del paciente el mismo día de la cirugía.

SUMMARY Objective: To describe the clinical outcomes of patients with unilateral inguinal hernia (UIH) treated in an ambulatory surgical unit (ASU) of a level III hospital. Methods: The clinical charts of patients treated at the ASU of Cayetano Heredia Hospital from July 2013 to June 2016 were reviewed. Results: 154 patients were included, mean age was 43 years; 101 (65.6%) were males; 104 (67.5%) had ASA I risk; 12 (7.8%) had underlying diseases; 94 (61.0%) undergone the open technique and 60 (39.0%) undergone laparoscopy. Laparoscopy was most frequently applied in women (p=0.037). Surgical time was higher in laparoscopic procedures (p=0.033). No significant differences were observed in variables such as age, surgical risk, anesthetic and surgical complications between open and laparoscopic procedures. Thirty-four (22%) patients were not discharged the day of the procedure: 8 (5.2%) presented complications and 26 (16.8%) had administrative or social reasons. Conclusion : Ambulatory surgery of UIH in adults either by open or laparoscopic procedures is safe and allows discharging patients the day of the procedure.

Dolor de cadera en adolescentes: estudio y tratamiento / Hip pain in adolescent: assessment and treatment

En adolescentes que consultan por dolor de cadera o pelvis, es crucial una adecuada historia clínica para orientarnos sobre la etiología del dolor y comprender los mecanismos que lo generan. Es importante conocer y realizar un exhaustivo examen físico, con especial énfasis en la cadera, incluyendo pruebas específicas para diferentes patologías, además de comprender las indicaciones de los diferentes estudios de imágenes, para así lograr un correcto diagnóstico.Entre las causas más frecuentes de coxalgia en adolescentes debemos considerar la epifisiolisis, el pinzamiento femoroacetabular con o sin roturas del labrum, las lesiones avulsivas de la pelvis, la coxa saltans, entre otras. Aunque son poco frecuentes, patologías sistémicas como reumatológicas y oncológicas también deben ser descartadas en adolescentes. Un diagnóstico de certeza nos permitirá realizar una adecuada estrategia de tratamiento, a fin de lograr una rehabilitación precoz y evitar futuras complicaciones.

In adolescents presenting with hip or pelvis pain, an adequate medical history is crucial to guide the etiology and understand the mechanisms that generate it. It is important to know and carry out an exhaustive physical examination, with special attention to the hip, including specific tests for different pathologies, in addition to understand the indications of the different imaging studies, in order to achieve a correct diagnosis. Among the most frequent causes of hip pain in adolescents, we must rule out slipped capital femoral epiphysis, femoroacetabular impingement with or without labral tears, avulsion lesions of the pelvis, snapping hip, among others. Although rare, systemic pathologies such as rheumatologic and oncologic diseases must also be ruled out in adolescents. An accurate diagnosis will allow us to carry out an adequate treatment strategy, in order to achieve early rehabilitation and avoid future complications.

Femoral hernia: uncommon, but associated with potentially severe complications / Hérnia femoral: incomum, mas associada a complicações potencialmente graves

ABSTRACT Background: Although the laparoscopic access is becoming the preferable treatment for femoral hernia, there are only few studies on this important subject. Aim: To assess the outcomes of the totally extraperitoneal laparoscopic (TEP) access in the treatment of femoral hernia. Methods: Data of 62 patients with femoral hernia who underwent herniorrhaphy were retrospectively reviewed. The diagnosis of femoral hernia was established by clinical and/or imaging exams in 55 patients and by laparoscopic findings in seven. Results: There were 55 (88.7%) females and 7 (11.3%) males, with female to male ratio of 8:1. The mean age was of 58.9±15.9 years, ranging from 22 to 92 years. Most patients (n=53; 85.5%) had single hernia and the remaining (n=9; 14.5%) bilateral, making a total of 71 hernias operated. Prior lower abdominal operations were recorded in 21 (33.9%) patients. Conversion to laparoscopic transabdominal preperitoneal procedure was performed in four (6.5%). Open herniorrhaphy was needed in two (3.2%), one with spontaneous enterocutaneous fistula in the groin region (Richter's hernia) and the another with incidental perforation of the adjacent small bowel that occurred during dissection of hernia sac. There was no mortality. Conclusion: Femoral hernia is uncommon, and it may be associated with potentially severe complications. Most femoral hernias may be successfully treated with totally extraperitoneal laparoscopic access, with low conversion and complication rates.

RESUMO Racional: Embora o acesso laparoscópico esteja se tornando o tratamento preferencial para a hérnia femoral, poucos são os estudos sobre esse importante assunto. Objetivo: Avaliar os resultados do acesso laparoscópico totalmente extraperitoneal no tratamento da hérnia femoral. Métodos: Os dados de 62 pacientes com hérnia femoral que foram submetidos a herniorrafia foram revisados ​​retrospectivamente. O diagnóstico foi estabelecido por exames clínicos e/ou de imagem em 55 pacientes e por achados laparoscópicos em sete. Resultados: Havia 55 (88,7%) mulheres e 7 (11,3%) homens, com proporção feminino/masculino de 8: 1. A média de idade foi de 58,9±15,9 anos (22-92). A maioria (n=53, 85,5%) apresentava hérnia única e o restante (n=9, 14,5%) bilaterais, perfazendo um total de 71 hérnias femorais operadas. Operações prévias no abdome inferior foram registradas em 21 (33,9%) pacientes. A conversão para procedimento pré-peritoneal transabdominal laparoscópico foi realizada em quatro (6,5%). Herniorrafia aberta foi necessária em dois pacientes (3,2%), um com fístula enterocutânea espontânea na região da virilha (hérnia de Richter) e o outro com perfuração incidental do intestino delgado adjacente que ocorreu durante a dissecção do saco herniário. Não houve mortalidade. Conclusão: A hérnia femoral é incomum e pode estar associada a complicações potencialmente graves. A maioria das hérnias femorais pode ser tratada com sucesso através do acesso laparoscópico totalmente extraperitoneal, com baixas taxas de conversão e complicações.

Forty-Five Cases of Chronic Testicular Pain and Groin Pain Treated with Kampo Medicine / 日本東洋医学雑誌

We examined Kampo treatment given to 45 patients with chronic testicular pain and groin pain. Thirty-three of 45 cases were healed with anti-percussive agents including keishibukuryogan, tokishakuyakusan. In addition to testicular pain, when the pain and numbness in the femoral lesion appeared, hachimijiogan and goshajinkigan were effective. If coldness in the lower body is an aggravating factor, tokishakuyakusan is considered appropriate as the first choice. We should notice the sign of qi-blood-fluid, especially, static blood, to select medicine for chronic testicular pain and groin pain.

Mucinous adenocarcinoma of the appendix with inguinal node metastases

Mucinous adenocarcinoma of the appendix is a rare neoplasm with a low propensity for lymph node metastasis. The present case refers to an appendicular mucinous adenocarcinoma with inguinal lymph node metastasis. A 71-year-old woman underwent an appendectomy due to a clinical presentation of acute appendicitis. However, the histological examination of the surgical specimen revealed a mucinous adenocarcinoma of the appendix. After staging, the patient underwent a right hemicolectomy and was proposed for adjuvant chemotherapy. At the 3rd year of follow-up, inguinal lymphadenopathy was diagnosed, which biopsy confirmed inguinal node metastases from primary colorectal cancer, with areas of extracellular mucin. Restaging revealed liver and peritoneal metastasis, and the patient was proposed for palliative chemotherapy. Appendicular neoplasms, due to their rarity, represent a diagnostic and therapeutic challenge. This clinical case depicts an unusual metastasis pathway for an unusual neoplasm.

Abordaje multidisciplinario del dolor inguinal crónico luego de hernioplastia inguinal / Multidisciplinary approach to chronic postoperative inguinal pain

RESUMEN Antecedentes: el dolor inguinal crónico posoperatorio representa una complicación que altera la ca lidad de vida después de la hernioplastia inguinal. Su incidencia es variable con informes de hasta el 16%. Objetivo: describir el tratamiento y los resultados en pacientes con dolor inguinal crónico luego de una hernioplastia inguinal con malla. Material y métodos: estudio descriptivo, observacional y retrospectivo. Se definió como dolor ingui nal crónico posoperatorio la presencia de dolor inguinal por daño nervioso o afectación del sistema somatosensorial tisular que persiste por más de 6 meses luego de la cirugía inicial. Se revisaron las historias clínicas de los pacientes que cursaban el posoperatorio de hernioplastia inguinal convencio nal y laparoscópica en el período 2010-2018. Se realizó la encuesta EuraHS Quality of life score antes y después del abordaje terapéutico multidisciplinario para evaluar cambios en el dolor y restricción de la actividad física. Los resultados fueron analizados y comparados. Resultados: se identificaron 8 pacientes con dolor inguinal crónico posoperatorio grave. El 100% fue evaluado por el Servicio de tratamiento del dolor y requirieron 3 o más fármacos para manejo del do lor. Posteriormente requirieron bloqueo guiado por tomografía computarizada a causa de la persisten cia de los síntomas. Se realizaron 3 (50%) exploraciones quirúrgicas con retiro de material protésico y 2 triples neurectomías. Se observó una disminución estadísticamente significativa (p < 0,05) en el dolor en reposo, dolor durante la actividad y dolor que experimentaron en la última semana. Conclusión: el abordaje multidisciplinario y escalonado permitiría seleccionar a los pacientes que se beneficiarán con el tratamiento quirúrgico.

ABSTRACT Background: Chronic postoperative inguinal pain represents a complication that alters the quality of life after inguinal hernioplasty. Its incidence is variable with reports of up to 16%. Objective: To describe the treatment and results in patients with chronic inguinal pain after an inguinal hernioplasty with mesh. Material and methods: Descriptive, observational and retrospective study. The postoperative chronic inguinal pain was defined as the presence of inguinal pain due to nerve damage or involvement of the somatosensory tissue system that persists for more than 6 months after the initial surgery. The medical records of patients in the postoperative period of conventional and laparoscopic inguinal hernioplasty in the period 2010-2018 were reviewed. The EuraHS Quality of life score pre and post multidisciplinary therapeutic approach was used to evaluate changes in pain and restriction of physical activity. The results were analyzed and compared. Results: 8 patients with severe chronic postoperative inguinal pain were identified. 100% were eva luated by the pain management service and required 3 or more drugs for pain management. Sub sequently, they required block guided by computed tomography due to persistence of symptoms. 3 (50%) surgical examinations were performed with removal of prosthetic material and 2 triple neurec tomies. A statistically significant decrease (p <0.05) was observed in pain at rest, pain during activity and pain experienced in the last week. Conclusion: The multidisciplinary and step up approach would allow selecting the patients who will benefit from the surgical treatment.

Comparative study of preservation versus elective division of ilioinguinal nerve on chronic groin pain after lichtenstein tension free inguinal hernia repair

Background: Post-hernioplasty chronic groin pain is one of the most important complications encountered after inguinal hernia repair. Routine ilioinguinal nerve excision has been proposed to avoid chronic post-hernioplasty neuralgia. The study aimed to evaluate the effect of routine ilioinguinal nerve excision compared to nerve preservation on chronic groin pain and other sensory symptoms in lichtenstein inguinal hernia repair.Methods: The study was conducted in the department of general surgery, at S.P. Medical College and PBM Hospital, Bikaner for duration of 15 months from august 2018 to November 2019. A total of 60 patients of uncomplicated inguinal hernia, who met the inclusion criteria, planned for lichtenstein hernioplasty were randomly divided into 2 groups with 30 cases with ilioinguinal nerve preservation (group A) and 30 cases with elective division of the nerve (group B). Follow up was done upto1 year and patients were inquired regarding pain, hypoesthesia and numbness and data was compared and analysed.Results: The incidence of post-operative neuralgia was 23.33% vs 6.67% (p=0.05) at 1 year in group A and group B respectively. The difference in pain was significant in both groups. The incidence of post-operative hypoesthesia was 10% vs 16.67% (p>0.05) at 1 year follow up in group A and group B respectively. The incidence of numbness was 11.11% vs 16.67% (p>0.05) at 1 year in group A and group B respectively. No statistically significant difference was found in both groups.Conclusions: The prophylactic exicision of ilioinguinal nerve during lichtenstein mesh repair decreases the incidence of chronic groin pain after surgery.

Comparative Effect of Static Stretching and Mulligan Stretching on Hip Adductor Flexibility in Footballers - A Two Group Trial

Groin pain due to adductor strain is commonly seen in footballers. Many methods of stretching a muscle likeballistic stretching, static stretching etc are used to increase flexibility of hip adductors and prevent groinstrain. Static hip adductor stretching till now is more favored technique whereas mulligan adductor stretchingis very new and popular method of increasing muscle flexibility. The present study was undertaken to comparethe effectiveness of 2 stretching programs i.e. Mulligan adductor stretching and static stretching on tight hipadductor. In this trial, 42 athletes who fulfilled the selection criteria were selected and then divided into twogroups based on block randomization. Group-1 received Mulligan’s adductor stretching while Group-2 receivedstatic stretching of hip adductors for 3 alternative days. Hip abduction range of motion (Abd-ROM) wasmeasured on baseline, after first day treatment and finally after third day treatment by a universal goniometer.Mean difference of Abd-ROM within groups on baseline, 1st day after treatment and 3rd day after treatmentwere -8.07, -12.76, -4.69 which shows highly significant difference (p = 0.00) between 3 sessions. MeanAbd-ROM between two groups has not shown significant different (F = 2.99, p > 0.05). It is concluded thatMulligan’s adductor stretching and static stretching both are equally effective in increasing Abd-ROM

Melanoma de escroto en un paciente de mediana edad / Scrotum melanoma in a middle-age patient

Se describe el caso clínico de un paciente de 42 años de edad, de piel negra, que asistió a la consulta de Cirugía de Tumores Periféricos en el Hospital Oncológico Docente Provincial Conrado Benítez García de Santiago de Cuba, por presentar una lesión oscura hiperpigmentada en el lado izquierdo del escroto, próxima a la región del rafe, de aproximadamente 4 mm y bordes irregulares, que no elevaba la piel ni dolía. Se realizó exéresis de la lesión y el estudio histopatológico reveló la existencia de un melanoma, sin ulceración ni satelitosis, con crecimiento radial, por lo que se profundizó en el área operada en busca de márgenes sin afectación y se resecaron los ganglios linfáticos inguinales bilaterales de manera profiláctica. Luego se indicó quimioterapia e inyecciones de interferón. El paciente mantenía una evolución favorable hasta el año y medio después de operado.

The case report of a 42 years, black skin patient is described, he attended the Peripheral Tumors Surgery Service in Conrado Benítez García Teaching Provincial Cancer Hospital in Santiago de Cuba, due to a hyperpigmented dark lesion in the left side of the scrotum, next to the raphe region, of approximately 4 mm and irregular borders that didn't elevate the skin or hurted. An excision of the lesion was carried out and the histological and pathological study revealed the existence of a melanoma, without ulceration or satelitosis, with radial growth, reason why there was a deep examination of the operated area in search of margins without affectation and the bilateral groin lymph nodes were dried up in a prophylactic way. Then chemotherapy and interferon injections were indicated. The patient maintained a favorable clinical course until a year and a half after the surgery.

Conservative management of an iliopsoas hematoma causing walking difficulty in an elderly patient on anticoagulation therapy: a case report

Spontaneous iliopsoas hematoma is a rare complication in patients suffering from bleeding disorders like hemophilia, Von Willebrand’s disease or those taking blood thinners like aspirin and clopidogrel or anticoagulant medications like warfarin for atrial fibrillation or post-thrombotic status. It can present as severe pain, muscle dysfunction, difficult walking or neurological dysfunction due to compression on femoral nerve or lumbar plexus. A high index of suspicion with early blood and radiological investigations like contrast enhanced computed tomography (CECT) or magnetic resonance imaging (MRI) of the part is immensely helpful in diagnosis and prompt management of such patients. A low hemoglobin or hematocrit level and a high INR is supportive while CECT or MRI of the abdomen and pelvis is confirmatory. Management in a hemodynamically and neurologically stable patient include immediate withdrawl of the anticoagulant, bed rest, infusion of I.V. fluids, vitamin K, fresh frozen plasma and packed red cell transfusion, which ensures complete recovery in most of the cases. However angio-embolization to control ongoing arterial bleeding is lifesaving when feasible or emergent open decompression and bleeding control surgery can save the life or prevent permanent neurological damage to the limb. Decompression of the hematoma by ultrasound or computed tomography guided catheter drainage is helpful alternative in few selected cases. We report an elderly patient on warfarin, who suddenly developed difficulty in walking within hours of a strained defecation, diagnosed to suffer from left iliopsoas hematoma and responded to conservative management with complete resolution of symptoms by 3 weeks.

Imaging Assessment of the Pubis in Soccer Players / Avaliação por imagem do púbis em jogadores de futebol

Abstract Objective To compare the accuracy of ultrasound (US) with that of magnetic resonance imaging (MRI) in the detection of aponeurosis lesions of the rectus abdominis/adductor longus muscles, to study the characteristics of the athletes and imaging findings associated with pubalgia, and to demonstrate the importance of each method in evaluating this condition. Materials and methods The present study was conducted from 2011 to 2016 with 39 professional soccer players: 15 with pubalgia and 24 without pubalgia. Age, field position, bodymass index (BMI), weekly training load, career length, and history of thigh/knee injury and lower back pain were recorded. The following tests were performed: radiographs (anteroposterior view of the pelvis in standing and flamingo positions) to evaluate hip impingement, sacroiliac joint, and pubic symphysis instability; US to analyze the common aponeurosis of the rectus abdominis/adductor longus muscles and inguinal hernias; and MRI for pubic bone degenerative alterations and edema, and lesions in the adductor and rectus abdominis muscles and their aponeurosis. Results There was an association between pubalgia, high BMI (p = 0.032) andmuscle alterations (p < 0.001). Two patients with pubalgia had inguinal hernias and one patient with pubalgia and two controls had sports hernias. Pubic degenerative changes were frequent in both groups. Aponeurosis lesions weremore frequent in patients with pain. The US detection had 44.4% sensitivity and 100% specificity. Conclusion The evaluation of athletic pubalgia should be performed with radiography, US, and MRI. High BMI, muscle injuries, geodes, and osteophytes are findings associated with pubalgia; US has low sensitivity to detect injuries of the common aponeurosis of the rectus abdominis/adductor longus muscles.

Resumo Objetivo Comparar a acurácia da ultrassonografia em relação à ressonância magnética na detecção de lesões da aponeurose do reto abdominal/adutor longo, estudar características dos jogadores e achados de imagem associados à pubalgia e demonstrar a importância de cada método. Materiais e métodos Estudo realizado de 2011 a 2016 com 39 jogadores profissionais de futebol, 15 deles com e 24 sem pubalgia. Foram registrados idade, posição, índice de massa corporal (IMC), carga de treino semanal, tempo de profissão e lesão prévia na coxa/joelho e lombalgia. Os seguintes exames de imagem foram realizados: radiografias (anteroposterior da bacia e flamingo) para avaliar sinais de impacto do quadril, articulações sacroilíacas e instabilidade da sínfise púbica; ultrassonografia para analisar a aponeurose comum do reto abdominal/adutor longo e hérnias inguinais e do esporte; ressonância magnética buscando alterações degenerativas e edema no púbis, lesões musculares dos adutores e retos abdominais e na sua aponeurose. Resultados Observou-se uma associação entre pubalgia e IMC elevado (p = 0,032) e alterações musculares (p < 0,001). Hérnia inguinal foi encontrada em dois casos e hérnia do esporte, em um caso e dois controles. Alterações degenerativas do púbis foram frequentes nos dois grupos. Lesões da aponeurose foram mais comuns nos pacientes com dor e a ultrassonografia teve sensibilidade de 44,4% e especificidade de 100% na detecção. Conclusão A avaliação da pubalgia atlética deve ser realizada com radiografias, ultrassonografia e ressonância magnética. Índice de massa corporal elevado, lesões musculares, geodos e osteófitos são achados associados à pubalgia; a ultrassonografia tem baixa sensibilidade para detectar lesões da aponeurose comum do reto abdominal/ adutor longo.

Study of epidemiology, clinicopathological correlation, prognostic factors and management in squamous cell carcinoma of vulva

Background: Carcinoma of the vulva is rare cancer, pruritus is the most common and long-lasting reported symptom. It is found to be associated with HPV and HIV infection. Currently, a more individualized and less radical treatment is suggested. In this study we evaluated epidemiology, clinicopathological prognostic factors, HPV distribution and risk factors for metastases to lymph nodes. We also reviewed multidisciplinary clinical management carried out at our institute.Methods: It is a prospective study of 25 biopsy proven cases of Squamous Cell Carcinoma of Vulva, treated at our center from September 2014 to September 2016. We collected the data regarding the clinical presentation, histological details, treatment given, survival and complications. HPV 16 and 18 testing were done using PCR method. Median follow up of the patients are for 24 months.Results: The mean age of patients was 54.6 years. Commonest presentation was perineal itching (36%). HPV 16/18 were positive in 25% of the patients. Radical vulvectomy with bilateral groin dissection was done in 14/25 (56%) patients. Among these 14 patients, 35.7 % (5/14) has lymph node metastases, disease free survival was 63.6% and overall survival was 81.1% for median follow up of 24 months. About one third of the patient presented with locally advanced disease.  Six (24%) patients received only chemo radiation as a treatment.Conclusions: HPV and HIV infection increase the risk of vulvar cancer. Individualization of treatment is necessary. The use of preoperative chemoradiation in locally advanced disease might have promising results in future.

Clinics in diagnostic imaging (197). Left ischiofemoral impingement syndrome

A 48-year-old woman presented with progressive left hip pain over six months, along with left lower limb weakness for two weeks. Magnetic resonance imaging of the left hip showed narrowing of the left ischiofemoral space, oedema of the left quadratus femoris muscle and left sciatic nerve, and mild bone marrow oedema of the left ischial tuberosity. The diagnosis of left ischiofemoral impingement syndrome was made. The imaging features of ischiofemoral impingement syndrome and the associated aetiologies and complications are discussed.

Unilateral versus Bilateral Groin Puncture for Atrial Fibrillation Ablation: Multi-Center Prospective Randomized Study

PURPOSE: Catheter ablation for atrial fibrillation (AF) requires heavy anticoagulation and uncomfortable post-procedural hemostasis. We compared patient satisfaction with and the safety of unilateral groin (UG) puncture-single trans-septal (ST) ablation with conventional bilateral groin (BG) puncture-double trans-septal (DT) ablation in paroxysmal AF patients. MATERIALS AND METHODS: We enrolled 222 patients with paroxysmal AF (59.4±10.7 years old) who were randomized in a 2:1 manner into UG-ST ablation (n=148) and BG-DT ablation (n=74) groups. If circumferential pulmonary vein isolation could not be achieved after three attempts of touch-up ablation in the UG-ST group, the patient was crossed over to BG-DT by performing a left groin puncture. RESULTS: Ten patients in the UG-ST group (6.8%) required crossover to the BG-DT approach. There were no significant differences in procedure time (p=0.144) and major complications rate (p>0.999) between the UG-ST and BG-DT groups. Access site pain (p=0.014), back pain (p=0.023), and total pain (p=0.015) scores were significantly lower for the UG-ST than BG-DT group as assessed by the Visual Analog Scale. Over 20.2±8.7 months of follow up, there was no difference in AF recurrence free-survival rates between the two groups (Log rank, p=0.984). CONCLUSION: UG-ST AF ablation is feasible and safe, and was found to significantly reduce post-procedural hemostasis-related discomfort, compared to the conventional DT approach, in patients with paroxysmal AF.
