    Objective: The aim of this study was to assess the efficacy and durability of infra-inguinal PTA in patients with CLI, in terms of clinical outcome. Design:Retrospective study of 50 consecutive patients with CLI that were exclusively treated by infra-inguinal PTA. Methods: The indications for intervention were rest pain in seven (14%) patients,non-healing ulcers in 27 (54%), and gangrenous lesions in 16 (32%).Thirty-three (66%) of these patients presented with a single arterial lesion, and the remaining 17 (34%) with multilevel arterial lesions.Kaplan-Meier analysis was used to assess survival, patency,limb-salvage rates, and amputation-free survival. Results: A total of 67 endovascular procedures were performed and 59 (88.1%) of them were considered to be technically successful. The median follow-up period was 12 months (interquartilerange: 17 months). The 30-day mortality was 4%, while the cumulative survival rates at 12, 24, and 36 months were 73%, 67%, and 59%,respectively. The cumulative primary patency rates at 12 and 24 months were 63% and 52%, respectively, and remained unchanged thereafter.The estimated secondary patency rate was 72% at 36 months. There was only one below-knee amputation in the patients that were treated exclusively with infra-inguinal PTA. The cumulative amputation-free survival at the same period was estimated at 60%. Conclusions: Infra-inguinal PTA had a good early and late outcome in this series of patients with a limited life expectancy.These results are comparable to historical results of surgical revascularization in the treatment of CLI. There is need for a randomized study to determine the primary optimal interventional approach for patients with CLI

    CONCLUSIONS: The preservation of saphenous vein during inguinal lymphadenectomy reduces the incidence of short-term and long-term complications without affecting the risk of local recurrence. Depending on the experience of the surgeon, the surgical strategy should be individualized and optimized for each patient with vulvar cancer.

    Aim: To compare extended-phase imaging using an extracellular space contrast agent, gadobenate dimeglumine, to imaging with a blood-pool contrast agent, gadofosveset, for magnetic resonance angiography. Materials and methods: A lower-limb magnetic resonance angiography (MRA) protocol (dynamic crural, three-station bolus chase, and infra-inguinal high resolution) designed for blood-pool agent imaging was adapted for use with the extracellular agent, gadobenate dimeglumine, primarily by using a triphasic injection protocol. Ten patients scanned with gadofosveset were compared to 10 patients scanned with gadobenate. The dynamic, bolus chase, and high-resolution images were scored for quality on a Likert scale (from 1–5). Signal- and contrast-to-noise ratios were analysed, and Mann–Whitney U statistical analysis performed. Results: There was no significant difference for the dynamic imaging or the aorto-iliac station of the bolus chase. Infra-inguinal bolus chase images were higher quality (p < 0.05 Mann–Whitney U test) with gadobenate. Signal analysis confirmed lower signal and contrast for venous imaging on the high spatial resolution acquisitions with gadobenate; however, this allowed improved arterial conspicuity. Conclusion: Extended-phase imaging using an extracellular space contrast agent is feasible and provides image quality to equal imaging with a blood-pool contrast agent.

    Current norms for renal vasculature hold true in only half the population. Standard textbooks perpetuate old misconceptions regarding renal venous anatomy. This study is aimed to determine left and right infra-renal angles (L-IRA, R-IRA); entry level of renal veins into the inferior vena cava (IVC), and height of IVC under renal vein influence; and their vertebral level. One hundred morphologically normal en-bloc renal specimens randomly selected from post-mortem examinations were dissected and resin casted. IRA were also measured from venograms of 32 adult and 11 foetal cadavers, as were vertebral entry levels. IRA measurements (degrees) were as follows: left, 55 degrees +/- 16 degrees (20 degrees -102 degrees ); right, 60 degrees +/- 17 degrees (10 degrees -93 degrees ). Left vein entered IVC higher than right 54%, lower 36%, and opposite each other 10%. Vertical distance between lower borders of veins was 1.0 +/- 0.9 cm. Vertical distance of IVC under renal vein influence was 2.3 +/- 1.0 cm. Vertebral level of veins in adults lies between TI2-L2. In foetuses, IRA was as follows: left, 65 degrees +/- 12 degrees (45 degrees -90 degrees ); right, 58 degrees +/- 7 degrees (40 degrees -70 degrees ); vertebral level between T12 and L3. Similar IRA values from literature noted on right, 51 degrees (26 degrees -100 degrees ); differences on left, 77 degrees (43 degrees -94 degrees ), clearly differing from Williams et al. (Gray's Anatomy, 37(th) ed, 1989) statement that renal veins "open into the inferior vena cava almost at right angles." Large variations of IRA are not surprising since kidneys are considered normally "floating viscera," varying position with posture and respiratory movement as well as in live vs. cadaveric subjects. The entry level into the IVC also differs from Williams et al. This study uniquely quantitated actual height difference between lower borders of left and right veins. The data presented appears to be the first documentation of vertebral

    We assessed the outcomes of a simplified technique for the percutaneous placement of a hepatic artery port-catheter system for chemotherapy infusion in advanced hepatocellular carcinoma with portal vein invasion. From February 2003 to February 2008, percutaneous hepatic artery port-catheter insertion was performed in 122 patients who had hepatocellular carcinoma with portal vein invasion. The arterial access route was the common femoral artery. The tip of the catheter was wedged into the right gastroepiploic artery without an additional fixation device. A side hole was positioned at the distal common hepatic artery to allow the delivery of chemotherapeutic agents into the hepatic arteries. Coil embolization was performed only to redistribute to the hepatic arteries or to prevent the inadvertent delivery of chemotherapeutic agents into extrahepatic arteries. The port chamber was created at either the supra-inguinal or infra-inguinal region. Technical success was achieved in all patients. Proper positioning of the side hole was checked before each scheduled chemotherapy session by port angiography. Catheter-related complications occurred in 19 patients (16%). Revision was achieved in 15 of 18 patients (83%). This simplified method demonstrates excellent technical feasibility, an acceptable range of complications, and is hence recommended for the management of advanced hepatocellular carcinoma with portal vein thrombosis

    Full Text Available BackgroundThe etiology of inguinal hernias remains uncertain even though the lifetime risk of developing an inguinal hernia is 27% for men and 3% for women. The aim was to summarize the evidence on hernia etiology, with focus on differences between lateral and medial hernias.ResultsLateral and medial hernias seem to have common as well as different etiologies. A patent processus vaginalis and increased cumulative mechanical exposure are risk factors for lateral hernias. Patients with medial hernias seem to have a more profoundly altered connective tissue architecture and homeostasis compared with patients with lateral hernias. However, connective tissue alteration may play a role in development of both subtypes. Inguinal hernias have a hereditary component with a complex inheritance pattern, and inguinal hernia susceptible genes have been identified that also are involved in connective tissue homeostasis.ConclusionThe etiology of lateral and medial hernias are at least partly different, but the final explanations are still lacking on certain areas. Further investigations of inguinal hernia genes may explain the altered connective tissue observed in patients with inguinal hernias. The precise mechanisms why processus vaginalis fails to obliterate in certain patients should also be clarified. Not all patients with a patent processus vaginalis develop a lateral hernia, but increased intraabdominal pressure appears to be a contributing factor.

  10. Inguinal Hernia in Athletes: Role of Dynamic Ultrasound.

    Inguinal hernia is a commonly encountered cause of pain in athletes. Because of the anatomic complexity, lack of standard imaging, and the dynamic condition, there is no unified opinion explaining its underlying pathology. Athletes with persistent groin pain would have a high prevalence of inguinal hernia with dynamic ultrasound, and herniorrhaphy would successfully return athletes to activity. Case-control study. Level 3. Forty-seven amateur and professional athletes with sports-related groin pain who underwent ultrasound were selected based on history and examination. Patients with prior groin surgery or hip pathology were excluded. Clinical and surgical documentation were correlated with imaging. The study group was compared with 41 age-matched asymptomatic athletes. Ultrasound was positive for hernia with movement of bowel, bladder, or omental tissue anterior to the inferior epigastric vessels during Valsalva maneuver. The 47-patient symptomatic study group included 41 patients with direct inguinal hernias, 1 with indirect inguinal hernia, and 5 with negative ultrasound. Of 42 patients with hernia, 39 significantly improved with herniorrhaphy, 2 failed to improve after surgery and were diagnosed with adductor longus tears, and 1 improved with physical therapy. Five patients with negative ultrasound underwent magnetic resonance imaging and were diagnosed with hip labral tear or osteitis pubis. The 41-patient asymptomatic control group included 3 patients with direct inguinal hernias, 2 with indirect inguinal hernias, and 3 with femoral hernias. Inguinal hernias are a major component of groin pain in athletes. Prevalence of direct inguinal hernia in symptomatic athletes was greater than that for controls ( P < 0.001). Surgery was successful in returning these athletes to sport: 39 of 42 (93%) athletes with groin pain and inguinal hernia became asymptomatic. Persistent groin pain in the athlete may relate to inguinal hernia, which can be diagnosed with dynamic

Lower limb regions (26 sides were carefully dissected as per the standard dissection procedure. Femoral vein (unitruncular was found in 96.15% of specimen. Bitruncular configurations (total bifidity was found in a male cadaver of 75 years of age (3.85%. In the right lower limb, 6.5 cms below the inguinal ligament the femoral vein - lateral ramus received the lateral circumflex femoral vein, and the medial circumflex femoral vein, and the lateral and medial ramii formed a common venous trunk. Knowledge of the truncular venous variations is important to recognize and avoid potential errors in diagnosis of deep venous thrombosis of the femoral vein, in the case of an occluded duplicated trunk.

    This is a case report of an adolescent male who underwent surgical ligation for a left-sided varicocele that recurred 2 years later. Standard retrograde embolization via the left renal vein was not possible, because there was no connection from the renal vein to the gonadal vein following surgical ligation. The patient was treated via antegrade access of the spermatic vein at the inguinal level with subsequent coil embolization.

    Inguinal hernia is thought to be common in rural Ghana, though no recent data exist on hernia prevalence in the country. This information is needed to guide policy and increase access to safe hernia repair in Ghana and other low-resource settings. Adult men randomly selected from the Barekese sub-district of Ashanti Region, Ghana were examined by surgeons for the presence of inguinal hernia. Men with hernia completed a survey on demographics, knowledge of the disease, and barriers to surgical treatment. A total of 803 participants were examined, while 105 participants completed the survey. The prevalence of inguinal hernia was 10.8 % (95 % CI 8.0, 13.6 %), and 2.2 % (95 % CI 0, 5.4 %) of participants had scars indicative of previous repair, making the overall prevalence of treated and untreated inguinal hernia 13.0 % (95 % CI 10.2, 15.7 %). Prevalence of inguinal hernia increased with age; 35.4 % (95 % CI 23.6, 47.2 %) of men aged 65 and older had inguinal hernia. Untreated inguinal hernia was associated with lower socio-economic status. Of those with inguinal hernia, 52.4 % did not know the cause of hernia. The most common reason cited for failing to seek medical care was cost (48.2 %). Although inguinal hernia is common among adult men living in rural Ghana, surgical repair rates are low. We propose a multi-faceted public health campaign aimed at increasing access to safe hernia repair in Ghana. This approach includes a training program of non-surgeons in inguinal hernia repair headed by the Ghana Hernia Society and could be adapted for use in other low-resource settings.

    Autogenous vein grafts remain the gold standard conduit for arterial bypass, particularly for the treatment of critical limb ischemia. Vein graft adaptation to the arterial environment, i.e., adequate dilation and wall thickening, contributes to the superior performance of vein grafts. However, abnormal venous wall remodeling with excessive neointimal hyperplasia commonly causes vein graft failure. Since the PREVENT trials failed to improve vein graft outcomes, new strategies focus on the ada...

    To compare the outcomes of management of incarcerated inguinal hernia by open versus laparoscopic approach. This is a retrospective analysis of incarcerated inguinal hernina in a paediatric surgery centre involving four consultants. Manual reduction was attempted in all and failure was managed by emergency surgery. The laparoscopy group had 27 patients. Four patients failed manual reduction and underwent emergency laparoscopic surgery. Three of them had small bowel strangulation which was reduced laparoscopically. The strangulated bowel was dusky in colour initially but changed to normal colour subsequently under vision. The fourth patient required appendectomy for strangulated appendix. One patient had concomitant repair of umbilical hernia and one patient had laparoscopic pyloromyotomy at the same time. One patient had testicular atrophy, one had hydrocoele and one had recurrence of hernia on the asymptomatic side. The open surgery group had 45 patients. Eleven patients had failed manual reduction requiring emergency surgery, of these two required resection and anastomosis of small intestine. One patient in this group had concomitant repair of undescended testis. There was no recurrence in this group, one had testicular atrophy and seven had metachronous hernia. Both open herniotomy and laparoscopic repair offer safe surgery with comparable outcomes for incarcerated inguinal hernia in children. Laparoscopic approach and hernioscopy at the time of open approach appear to show the advantage of repairing the contralateral patent processus vaginalis at the same time and avoiding metachronous inguinal hernia.

    Current lymphogranuloma venereum (LGV) guidelines mainly focus on anorectal infections. Inguinal LGV infections have been rare in the current epidemic among men who have sex with men (MSM), but might require a different approach not yet recommended in current guidelines for the treatment and diagnosis of LGV. We describe 4 inguinal LGV cases. Three MSM developed inguinal LGV infection several weeks after a previous consultation, of which two had received azithromycin after being notified for LGV. Three failed the recommended 21 days doxycycline treatment. These inguinal LGV cases highlight 3 pitfalls in the current standard management of LGV: (1) Urethral chlamydia infections in MSM can be caused by LGV biovars that in contrast to non-LGV biovars require prolonged antibiotic therapy. (2) The recommended one gram azithromycin contact treatment seems insufficient to prevent established infections. (3) Inguinal LGV may require prolonged courses of doxycycline, exceeding the currently advised 21 days regimen. Published by the BMJ Publishing Group Limited.

    Inguinal hernia repair is the most common procedure in pediatric surgery. Suture techniques for laparoscopic inguinal hernia repair in children are easy to perform and popular with a low recurrence rate. The aim of this study was to evaluate the effect of laparoscopic preperitoneal injection of three-dimensional gel on closing of the inguinal hernia sac (IHS) in laboratory animals. With the animals under general anesthesia, we performed peritoneoscopy in 12 male Chinchilla rabbits weighing 1200-1400 g. The endoscope was introduced into the abdominal cavity, and bilateral deep inguinal rings were identified. A Tuohy needle with the injectable polymeric bulking agent DAM+™ (three-dimensional polyacrylamide gel with silver ions [Argiform(®) from Bioform(®)]) was introduced preperitoneally. The implant was then injected across the entire orifice of the deep inguinal rings and draped over the cord structures. After completion of bilateral repairs, the rabbits were extubated and observed in the animal laboratory. Then the second laparoscopy was performed 6 months later, and the deep inguinal rings were inspected. The postoperative course was uneventful in all the animals. At the second laparoscopy no reopening of the entire orifice of the deep inguinal rings was noted. Accurate placement of the polymeric agent and adequate coverage of the vas deferens were accomplished in all the animals. This study demonstrates that the biopolymeric implant gives good postoperative results and a stable trend of closing the IHS in long-term follow-up. In conclusion, we hope that injectable polymeric bulking agents can be used for treatment of inguinal hernias of pediatric patients after additional animal and human research.

    Objective: To compare the postoperative pain in inguinal hernioplasty, by preserving versus wide elective division of ilioinguinal nerve. Study Design: Randomized controlled trial. Place and Duration of Study: Surgical Department, Civil Hospital, Karachi, from January till August 2015. Methodology: All patients of either gender above 15 years of age, undergoing mesh repair for unilateral, reducible inguinal hernia, were included. Patients with recurrent inguinal hernia, bilateral inguinal hernia, and those who will require emergency hernia surgeries like irreducible, obstructed, and strangulated hernia, were excluded. They were randomly assigned 42 into inguinal nerve preservation group (group A) and 42 in division (group B). Postoperative pain was assessed at first day, at discharge and after one month using visual analogue scale. Results: There were a total of 84 patients. Group A patients had median (IQR) pain scores of 5 (1) and 3 (2) as compared to group B pain scores of 4 (2) and 2 (1) at 24 hours of surgery and at discharge, respectively (p <0.05). Median (IQR) postoperative pain score one month after inguinal hernioplasty was 2.5 (1) in group A, while 0.5 (1) in group B (p <0.05). A significant decline in the pain scores were observed in group B from the first day of surgery till one month afterwards (p <0.05). Conclusion: Wide resection of ilioinguinal nerve has a lower frequency of postoperative pain in comparison to the ilioinguinal nerve preservation, in inguinal hernioplasty. (author)

    Eastburn, Elizabeth; Hernandez, Maria A; Boretsky, Karen

    2017-11-01

    Hip arthroscopic surgery is performed on older pediatric patients. Fascia iliaca compartment block has proven efficacy in providing analgesia following hip surgery and can be performed with target location of local anesthetic below or above the inguinal ligament. The reported success of ultrasound-guided infra-inguinal fascia iliaca compartment block is lower when compared to traditional landmark technique, while the reliability of supra-inguinal fascia iliaca compartment block is unreported. The primary aim was to report the results in obtaining sensory changes in the distribution of the femoral and lateral femoral cutaneous nerves following supra-inguinal fascia iliaca compartment block in patients undergoing arthroscopic hip surgery. Secondary outcomes are the ability to find echogenic landmarks and to report pain scores and opioid consumption. We reviewed the electronic medical record and regional anesthesia database of patients receiving ultrasound-guided fascia iliaca compartment block for arthroscopic hip surgery. Sensory changes to the femoral and lateral femoral cutaneous nerves were determined. Identification of echogenic landmarks was quantified. Pain scores and opioid consumption were determined. Seventeen patients of mean age 15.4 years old (SD 1.3; range 13-17 years) were included. Sensory changes to both the femoral and lateral femoral cutaneous nerves occurred in 94% of patients (95% CI: 82%-100%). The average volume of ropivacaine 0.2% was 0.53 mL/Kg (SD 0.11 mL/Kg). Echogenic landmarks were identified in all patients. Pain scores and opioid consumption were generally low. A supra-inguinal location for the deposition of local anesthetic when performing fascia iliaca nerve block for hip surgery is reliable in anesthetizing the femoral and lateral femoral cutaneous nerves and should encourage investigation into the clinical efficacy. © 2017 John Wiley & Sons Ltd.

    GUI(Graphic User Interface) has been developed for high burnup fuel performance code INFRA. Based upon FORTRAN program language, INFRA was developed by COMPAQ Visual FORTRAN 6.5. Graphic user input and output interface have been developed by using Visual Basic and MDB which are the most widely used program language and database for windows application development. Various input parameters, which are required for INFRA calculation, can be input more conveniently by newly developed input interface. Without any additional data handling, INFRA calculation results can be investigated intuitively by 2D or 3D graphs on screen and animation function

    Major tributaries such as the renal and adrenal veins have been studied extensively; however, tributaries of the infra-renal segment of the inferior vena cava (IVC) have not been given much attention. Accurate knowledge of the anatomy of these veins is necessary for improved efficacy of surgical interventions in the retroperitoneum. The aim of this study therefore was to provide a comprehensive picture of the internal anatomy of the tributaries of the infra-renal segment of the IVC. Dissection of the posterior abdominal wall was performed on 30 formalin-fixed cadavers. Endoscopic study was carried out followed by a midline venotomy on the anterior wall of the isolated IVC, the location and orientation of its tributaries and their ostia were observed and measurements taken. The results showed that while there was great variation in the drainage pattern of the lumbar veins, most lumbar veins had ostia located between L2 and L3 vertebrae irrespective of the location of renal and gonadal tributaries. Valves were found in 81.81 % of gonadal veins, in 56.60 % of all lumbar veins and discrete ostial valves in 14.81 % of renal veins. The location of the tributaries of the IVC was correlated with the vertebral levels. Empirical data regarding their ostio-valvular complexes were established, which put into question widely accepted concept of valveless tributaries. Our results may implicate surgical procedures in and around the retroperitoneal region.

    Full Text Available A 56-year-old woman presented with gradually worsening shortness of breath associated with dull left leg pain over 5 days. She denied any recent travel, recent surgeries or immobilization. CT pulmonary angiography and CT venography revealed multiple bilateral pulmonary emboli and extensive left pelvic and left lower extremity deep vein thromboses. Contrast-enhanced CT showed that the right common iliac artery crossed the left common iliac vein and compressed it externally, indicative of May–Thurner syndrome. Catheter-directed thrombolysis of the left lower extremity was performed and heparin infusion was started. The patient also underwent left iliac vein balloon angioplasty with stenting and infra-renal inferior vena cava filter placement via the jugular approach to prevent further embolization.

    For patients with recurrent inguinal hernia, or bilateral inguinal hernia, or for women, laparoscopic repair offers significant advantages over open techniques with regard to recurrence risk, pain, and recovery. For unilateral first-time hernias, either laparoscopic or open repair with mesh can offer excellent results. The major drawback of laparoscopy is that the technique requires a significant number of cases to master. For surgeons in group practice, it makes sense to have one surgeon in ...

    Purpose: To evaluate the benefit of prophylactic inguinal irradiation (PII) in anal canal squamous cell carcinoma (ASCC). Methods and Materials: This retrospective study analyzed the outcome of 208 patients presenting with ASCC treated between 2000 and 2004 in four cancer centers of the south of France. Results: The population study included 35 T1, 86 T2, 59 T3, 20 T4, and 8 T stage unknown patients. Twenty-seven patients presented with macroscopic inguinal node involvement. Of the 181 patients with uninvolved nodes at presentation, 75 received a PII to a total dose of 45–50 Gy (PII group) and 106 did not receive PII (no PII group). Compared with the no PII group, patients in the PII group were younger (60% vs. 41% of patients age 2 toxicity of the lower extremity was observed. Conclusion: PII with a dose of 45 Gy is safe and highly efficient to prevent inguinal recurrence and should be recommended for all T3-4 tumors. For early-stage tumors, PII should also be discussed, because the 5-year inguinal recurrence risk remains substantial when omitting PII (about 10%).

    Tension-free mesh repair of inguinal hernia has led to uniformly low recurrence rates. Morbidity associated with this operation is mainly related to chronic pain. No consensus guidelines exist for the management of this condition. The goal of this study is to design an expert-based algorithm for diagnostic and therapeutic management of chronic inguinal postoperative pain (CPIP). A group of surgeons considered experts on inguinal hernia surgery was solicited to develop the algorithm. Consensus regarding each step of an algorithm proposed by the authors was sought by means of the Delphi method leading to a revised expert-based algorithm. With the input of 28 international experts, an algorithm for a stepwise approach for management of CPIP was created. 26 participants accepted the final algorithm as a consensus model. One participant could not agree with the final concept. One expert did not respond during the final phase. There is a need for guidelines with regard to management of CPIP. This algorithm can serve as a guide with regard to the diagnosis, management, and treatment of these patients and improve clinical outcomes. If an expectative phase of a few months has passed without any amelioration of CPIP, a multidisciplinary approach is indicated and a pain management team should be consulted. Pharmacologic, behavioral, and interventional modalities including nerve blocks are essential. If conservative measures fail and surgery is considered, triple neurectomy, correction for recurrence with or without neurectomy, and meshoma removal if indicated should be performed. Surgeons less experienced with remedial operations for CPIP should not hesitate to refer their patients to dedicated hernia surgeons.

    Objective: To evaluate the palliative therapeutic effects of transjugular intrahepatic portosystemic shunt (TIPS) in portal vein tumor thrombosis (PVTT) complicated with portal vein hypertension, and to discuss the technical skills. Methods: There were 14 cases of end-stage hepatocellular carcinoma complicated with PVTT and portal vein hypertension, the average age was 53.6 yr. There were 8 cases with complete occlusion of main portal vein, 6 eases with incomplete thrombosis, and 5 cases combined with portal vein cavernous transformation. One case had simple hemorrhage, 3 eases had intractable ascites, and 10 cases had hemorrhage accompanied by intractable ascites. Results: The procedure of TIPS was successful in 10 cases, the successful rate was about 71%. The mean portal vein pressure was reduced from 37.2 mm Hg to 18.2 mm Hg, with an average reduction of 19.0 mm Hg. After the procedure of TIPS, the ascites decreased, hemorrhage stopped and the clinical symptoms disappeared. The average survival period was 132.3 days. The procedure were failing in 4 cases. Conclusion: TIPS was an effective palliative therapeutic methods to control the hemorrhage and ascites aroused by hepatic carcinoma complicated with PVTT

    Recurrence after inguinal hernia surgery is a considerable clinical problem, and several risk factors of recurrence such as surgical technique, re-recurrence, and family history have been identified. Non-technical patient related factors that influence the risk of recurrence after inguinal hernia surgery are sparsely studied. The purpose of the studies included in this PhD thesis, was to describe the epidemiologic characteristics of inguinal hernia occurrence and recurrence, as well as investigating the patient related risk factors leading to recurrence after inguinal hernia surgery. Four studies were included in this thesis. Study 1: The study was a nationwide register-based study combining the Civil Registration System and the Danish National Hospital Register during a five-year period. We included a total of 46,717 persons operated for a groin hernia from the population of 5,639,885 people (2,799,105 males, 2,008,780 females). We found that 97% of all groin hernia repairs were inguinal hernias and 3% femoral hernias. Data showed that inguinal hernia surgery peaked during childhood and old age, whereas femoral hernia surgery increased throughout life. Study 2: Using data from the Danish Hernia Database (DHDB), we included all male patients operated for elective primary inguinal hernia during a 15-year period (n = 85,314). The overall inguinal hernia reoperation rate was 3.8%, and subdivided into indirect inguinal hernias and direct inguinal hernias, the reoperation rates were 2.7% and 5.2%, respectively (p thesis have studies the natural history of groin hernias on a nationwide basis; have identified the epidemiologic distribution of groin hernias and the non-technical risk factors associated with recurrence. Data showed that non-technical patient-related risk factors have great impact on the risk of recurrence after inguinal hernia surgery. The reason to why inguinal hernias recur is most likely multifactorial and lies in the span of technical and non

  1. Infra-sound cancellation and mitigation in wind turbines

    The infra-sound spectra recorded inside homes located even several kilometres far from wind turbine installations is characterized by large pressure fluctuation in the low frequency range. There is a significant body of literature suggesting inaudible sounds at low frequency are sensed by humans and affect the wellbeing through different mechanisms. These mechanisms include amplitude modulation of heard sounds, stimulating subconscious pathways, causing endolymphatic hydrops, and possibly potentiating noise-induced hearing loss. We suggest the study of infra-sound active cancellation and mitigation to address the low frequency noise issues. Loudspeakers generate pressure wave components of same amplitude and frequency but opposite phase of the recorded infra sound. They also produce pressure wave components within the audible range reducing the perception of the infra-sound to minimize the sensing of the residual infra sound.

    The development of laparoscopic hernia repair has provided an alternative approach to the management of incarcerated inguinal hernia in children. Different laparoscopic techniques for hernia repair have been described. However, we hereby review the role of laparoscopic hernia repair using the hook method in the emergency setting for incarcerated inguinal hernias in children. A retrospective review was conducted of all children who presented with incarcerated inguinal hernia and underwent laparoscopic hernia repair using the hook method in emergency setting between 2004 and 2010. There were a total of 15 boys and 1 girl with a mean age of 30 ± 36 months (range, 4 months to 12 years). The hernia was successfully reduced after sedation in 7 children and after general anesthesia in 4 children. In 5 children, the hernia was reduced by a combined manual and laparoscopic-assisted approach. Emergency laparoscopic inguinal hernia repair using the hook method was performed after reduction of the hernia. The presence of preperitoneal fluid secondary to recent incarceration facilitated the dissection of the preperitoneal space by the hernia hook. All children underwent successful reduction and hernia repair. The median operative time was 37 minutes. There was no postoperative complication. The median hospital stay was 3 days. At a median follow-up of 40 months, there was no recurrence of the hernia or testicular atrophy. Emergency laparoscopic inguinal hernia repair by the hook method is safe and feasible. Easier preperitoneal dissection was experienced, and repair of the contralateral patent processus vaginalis can be performed in the same setting. Copyright © 2011 Elsevier Inc. All rights reserved.

Seventeen patients treated between January 2008 and September 2010 without evidence of inguinal and distant metastasis were retrospectively reviewed. In 9 patients with technique 1, dose to inguinal and whole pelvis area was 41.4 to 45 Gy and total dose was 59.4 Gy. In 8 patients with technique 2, doses to inguinal, whole pelvis, gross tumor were 36 to 41.4 Gy, 36 to 41.4 Gy, and 45 to 54 Gy, respectively. The median follow-up period was 27.6 and 14.8 months in group technique 1 and 2, respectively. The incidences of grade 3 radiation dermatitis were 56% (5 patients) and 50% (4 patients), dose ranges grade 3 dermatitis appeared were 41.4 to 50.4 Gy and 45 to 54 Gy in group technique 1 and 2, respectively (p = 0.819). The areas affected by grade 3 dermatitis in 2 groups were as follow: perianal and perineal areas in 40% and 25%, perianal and inguinal areas in 0% and 50%, and perianal area only in 60% and 25%, respectively (p = 0.196). No inguinal failure has been observed. Photon thunderbird with deep match technique and 3-field technique with electron inguinal boost showed similar incidence of radiation dermatitis. However, photon thunderbird with deep match seems to increase the possibility of severe perineal dermatitis.

    Acute testicular ischemia caused by an incarcerated inguinal hernia usually affects infants. There are few reports of diagnosis using US, and the effect of long-standing reducible hernias on testicular growth in infants and children is unknown. The objectives of this study were to determine the incidence of testicular ischemia secondary to an incarcerated inguinal hernia at scrotal sonography and to determine the effect on testicular size at diagnosis. A hospital database was used to locate scrotal sonography examinations documenting an inguinal hernia, and images were reviewed for signs of testicular ischemia. Testicular volumes were compared using the Wilcoxon signed rank test. A total of 147 patients were identified with an inguinal hernia (age 1 day to 23 years, average 6 years). Ten patients (6.8%) had associated testicular ischemia (age 3 weeks to 6 months, average 9 weeks) and showed a statistically significant increase in ipsilateral testicular size compared to the contralateral testicle (P = 0.012). Patients without testicular ischemia did not show a significant difference in testicular size, regardless of patient age. An incarcerated inguinal hernia should be considered as a cause of acute testicular ischemia in infants younger than 6 months of age.

    We report a case of endometriosis in the right inguinal region, attached to the right round ligament in a 28-year-old woman. At the age of 20, laparoscopic left ovarian cystectomy and pelvic adhesiolysis for endometriosis was carried out. She noticed a right tender groin mass 7 months previously, and the tumour size fluctuated with the menstrual cycle. A poorly circumscribed elastic hard mass, measuring 3 cm in diameter, was palpated in her right inguinal region. Magnetic resonance imaging showed a 2.5 cm x 2.5 cm mass in the right inguinal canal and a 5.4 cm x 6.8 cm mass was seen in the left ovary. The mass enlarged during menstruation. The groin mass was removed, in addition to carrying out laparoscopic ovarian cystectomy. At operation, the groin mass was found to be in continuity with the round ligament of extraperitoneal portion. Histological diagnosis of endometriosis was made in both ovarian and inguinal tumours. After surgery, the pain disappeared completely. Worth mentioning is that MRI clearly showed the change of tumour size depending on the menstrual cycle, which aided in arriving at the correct diagnosis of endometriosis in an unusual location

    Inguinal hernia is relatively common in children. Although inguinal hernia is not frequently encountered in girls in comparison to boys, there are occasional cases of uterine or ovarian herniation in female indirect inguinal hernia. Incarcerated ovary in hernia sac has the risk of torsion and strangulation. We present an 8-year-old girl with painful mass in her left groin. With computed tomography (CT) and ultrasonography (US), we made the diagnosis of ovarian strangulation within an incarcerated inguinal hernia. Since ultrasound is primarily used for evaluation of groin mass, CT findings of an incarcerated inguinal hernia is rarely reported.

    Portal vein embolization (PVE) may be performed before hemihepatectomy to increase the volume of future liver remnant (FLR) and to reduce the risk of postoperative liver insufficiency. We report the case of a 71-year-old patient with hilar cholangiocarcinoma undergoing PVE with access from the right portal vein using a mixture of n-butyl-2-cyanoacrylate and ethiodized oil. During the procedure, nontarget embolization of the left portal vein occurred. An aspiration maneuver of the polymerized plug failed; however, the embolus obstructing portal venous flow in the FLR was successfully relocated into the right portal vein while carefully bypassing the plug with a balloon catheter, inflating the balloon, and pulling the plug into the main right portal vein.

    Thirty-five patients with clinically N0 cancers of the canal anal, 33 epidermoid carcinomas et 2 melanomas were histologically staged with inguinal sentinel lymphode biopsy (ISN). With the combined technique, blue dye and radiocolloid the ISN was identified in 100 % of the cases. The ISN was invaded in 7 cases/33 for epidermoid tumors and 2/2 for melanomas. After 18 months of follow-up, no inguinal recurrence could be seen in ISN pN0 cases. In conclusion, ISN biopsy is a reliable procedure to stage anal,, canal cancers. It should prevent unnecessary prophylactic inguinal irradiation for pN0 ISN. Inguinal irradiation is only indicated in pN1 ISN. (author)

    Herniography frequently reveals clinically undetected groin hernia. Thereby herniography contributes to the clinical work-up in patients with obscure groin pain. However, the distinction between clinically important and unimportant abnormalities within the lateral inguinal fossa can be difficult. This study was therefore designed in order to elucidate the herniographic appearance of the lateral inguinal fossa in patients with obscure groin pain. Herniographic findings were compared with laterality of the patients' symptoms. The lateral umbilical fold was visible in only 47% of the groins. A triangular shaped outpouching from the lateral inguinal fossa and a patent processus vaginalis were found with equal frequency on the left and right side. They were five times as frequent in men as in women. Their presence did not correlate with laterality of the patients' symptoms. Indirect hernias were almost twice as common on the symptomatic side as compared with the asymptomatic side. On the left side they were found twice as often in men as in women while there was no significant sex difference on the right side. Our results show that neither a patent processus vaginalis nor a triangular outpouching from the lateral inguinal fossa correlate with the laterality of the patients' symptoms while true indirect hernias do.

    Elective inguinal hernia repair as a day case is a safe and suitable procedure, with well-recognized feasibility. The increasing number of elderly patients requiring inguinal hernia repair leads clinicians to admit a growing number of outpatients. The aim of the current study was to analyze the outcomes (feasibility and safety) of day case treatment in elderly patients. Eighty patients >80 years of age and 80 patients ≤55 years of age underwent elective inguinal hernia repairs under local anesthesia. There were no mortalities or major complications in the elderly undergoing inguinal herniorraphies as outpatients, and only one unanticipated admission occurred in the younger age group. Elective inguinal hernia repair in the elderly has a good outcome, and age alone should not be a drawback to day case treatment. Copyright © 2014 Surgical Associates Ltd. Published by Elsevier Ltd.

    Local anaesthesia has been identified as the most favourable anaesthesia for elective inguinal hernia repair with respect to complication rate, cost effectiveness and overall patients' satisfaction. This study was conducted to determine the efficacy of local anaesthesia in inguinal hernia in terms of pain relief, wound infection and hospital stay. Methods: In this randomized controlled trial (RCT), 60 patients with inguinal hernia were included at the General Surgical 'B' Unit, Ayub Teaching Hospital Abbottabad. Results: The day-case rates were significantly higher when patients underwent surgery under LA compared to GA (82.6 percent versus 42.6 percent). The incidence of urinary retention was higher in the GA group (p<0.05). There were 17 (2.9 percent) re-admissions overall. The reasons for re-admission included haematoma (n=6), severe pain (n=4), infection (n=3), fainting (n=2) and urinary retention (n=2). Conclusion: This study demonstrates that local anaesthesia for inguinal hernia repair has better efficacy as compared to general anaesthesia. (author)

    Laparoscopic inguinal hernia repair has been shown to have multiple advantages compared with open repair such as less postoperative pain and earlier resume of daily activities with a comparable recurrence rate. We speculate robotic inguinal hernia repair may yield equivalent benefits, while providing the surgeon added dexterity. One hundred consecutive robotic inguinal hernia repairs with mesh were performed with a mean age of 56 years (25-96). Fifty-six unilateral hernias and 22 bilateral hernias were repaired amongst 62 males and 16 females. Polypropylene mesh was used for reconstruction. All but, two patients were completed robotically. Mean operative time was 52 minutes per hernia repair (45-67). Five patients were admitted overnight based on their advanced age. Regular diet was resumed immediately. Postoperative pain was minimal and regular activity was achieved after an average of four days. One patient recurred after three months in our earlier experience and he was repaired robotically. Mean follow-up time was 12 months. These data, compared with laparoscopic approach, suggest similar recurrence rates and postoperative pain. We believe comparative studies with laparoscopic approach need to be performed to assess the role robotic surgery has in the treatment of inguinal hernia repair.

  2. Unusual Initial Presentation of Herpes Simplex Virus as Inguinal Lymphadenopathy

    Full Text Available Genital herpes simplex virus (HSV infections are a common cause of inguinal lymphadenopathy. However, surgical excision of enlarged inguinal nodes is almost never performed to initially diagnose genital herpes simplex virus, due to the distinct external presentation of genital herpetic vesicles that usually occur with the first symptoms of infection. Therefore, the histologic and immunophenotypic features of HSV-associated inguinal lymphadenopathy are unfamiliar to most pathologists. The current report describes the lymph node pathology of two immunocompetent patients, whose initial HSV diagnosis was established through surgical excision of enlarged inguinal lymph nodes. Histologic examination showed features consistent with viral lymphadenopathy, including florid follicular hyperplasia, monocytoid B-cell hyperplasia, and paracortical hyperplasia without extensive necrosis. Immunohistochemical stains for HSV antigens, using polyclonal anti-HSV I and II antibodies, demonstrate strong immunoreactivity for HSV in a small number of cells in the subcapsular sinuses, especially in areas with monocytoid B-cell hyperplasia. Rare scattered HSV-positive cells also are identified in paracortical areas and germinal centers. We conclude that an initial diagnosis of genital HSV infection may be established by inguinal lymph node biopsy.

    In this study, the use of medications for analgesia and/or sedation for incarcerated inguinal hernia reductions in the emergency department was analyzed. A retrospective chart review was conducted for all patients presenting to a pediatric emergency department with incarcerated inguinal hernia from 2002 to 2005. A total of 99 children presented with incarcerated hernias during the study period. The median age was 11 months. Forty-four percent of children received medication for the procedure, of them 75% received parenteral and 25% oral or intranasal medications. Forty-five percent of children who received medication went through at least 1 hernia reduction attempt initially without medications. More than half the children with incarcerated inguinal hernias did not receive any medication for pain and/or sedation prior to hernia reduction. Guidelines for medication use for children with incarcerated inguinal hernias need to be developed.

    A realistic simulator for transabdominal preperitoneal (TAPP) inguinal hernia repair would enhance surgeons' training experience before they enter the operating theater. The purpose of this study was to create a novel physical simulator for TAPP inguinal hernia repair and obtain surgeons' opinions regarding its efficacy. Our novel TAPP inguinal hernia repair simulator consists of a physical laparoscopy simulator and a handmade organ replica model. The physical laparoscopy simulator was created by three-dimensional (3D) printing technology, and it represents the trunk of the human body and the bendability of the abdominal wall under pneumoperitoneal pressure. The organ replica model was manually created by assembling materials. The TAPP inguinal hernia repair simulator allows for the performance of all procedures required in TAPP inguinal hernia repair. Fifteen general surgeons performed TAPP inguinal hernia repair using our simulator. Their opinions were scored on a 5-point Likert scale. All participants strongly agreed that the 3D-printed physical simulator and organ replica model were highly useful for TAPP inguinal hernia repair training (median, 5 points) and TAPP inguinal hernia repair education (median, 5 points). They felt that the simulator would be effective for TAPP inguinal hernia repair training before entering the operating theater. All surgeons considered that this simulator should be introduced in the residency curriculum. We successfully created a physical simulator for TAPP inguinal hernia repair training using 3D printing technology and a handmade organ replica model created with inexpensive, readily accessible materials. Preoperative TAPP inguinal hernia repair training using this simulator and organ replica model may be of benefit in the training of all surgeons. All general surgeons involved in the present study felt that this simulator and organ replica model should be used in their residency curriculum.

    2006-03-01

    The purpose of this study was to describe the laparoscopic approach to incarcerated inguinal hernia in children. After unsuccessful manual reduction, 29 patients (aged 3 weeks to 7 years; median, 10 weeks; 44 boys, 15 girls) with incarcerated inguinal hernia underwent immediate laparoscopy. The hernial content was reduced in a combined technique of external manual pressure and internal pulling by forceps. The bowel was inspected, and the hernia was repaired. In all patients, the procedure was successful. No conversion to the open approach was required. Immediate laparoscopic herniorrhaphy in the same session was added. No complications occurred. Laparoscopy allowed for simultaneous reduction under direct visual control, inspection of the incarcerated organ, and definitive repair of the hernia. Technically, it appears easier than the conventional approach because of the internal inguinal ring being widened by intraabdominal carbon dioxide insufflation. The hospital stay is shorter.

    Background: Hernioplasty for Inguinal hernia is one of the commonest operations performed in general surgical wards. More recently, interest has waxed and waned regarding the minimally invasive approach to hernioplasty. This study was carried out to assess the management outcome of minimally invasive hernioplasty (Totally extra-peritoneal approach) as the treatment of choice for uncomplicated (incomplete and reducible) inguinal hernia. Method: In this quasi experimental study patients aged between 14-83 years who were otherwise fit and willing for total extra-peritoneal laparoscopic repair were recruited prospectively over a 10 month period. Thirty-seven such patients were operated and followed up in the hernia clinics. Six cases were later excluded for lack of proper follow-up. Results: The typical patient was middle-aged male with right-sided inguinal hernia. Mean operating time was 53.3 minutes. No conversion was undertaken; however, there was one case of small bowel injury that went unrecognized on-table but necessitated subsequent laparotomy. Overall morbidity was 13.5 percentage. Mean length of hospitalization was 2.89 days. Mean duration to normal routine life was 9.25 days. Overall, 70.9 percentage of patients expressed satisfaction with the surgery. Conclusion: Totally extra-peritoneal mesh repair is a new and safe technique for hernioplasty with acceptable rates of morbidity and it is procedure of choice for recurrent and bilateral inguinal hernias and also used as alternate to open hernioplasty for uncomplicated (incomplete and reducible) inguinal hernia.

  13. Multimodal ultrasonographic assessment of leiomyosarcoma of the femoral vein in a patient misdiagnosed as having deep vein thrombosis

    2017-01-01

    Abstract Rationale: Primary leiomyosarcoma (LMS) of the vein is a rare tumor that arises from the smooth muscle cells of the vessel wall and has an extremely poor prognosis. This tumor can occur in vessels such as the inferior vena cava, great saphenous vein, femoral vein, iliac vein, popliteal vein, and renal vein; the inferior vena cava is the most common site. LMS of the femoral vein can result in edema and pain in the lower extremity; therefore, it is not easy to be differentiated from deep vein thrombosis (DVT). Moreover, virtually no studies have described the ultrasonographic features of LMS of the vein in detail. Patient concerns: We present a case of a 55-year-old woman with LMS of the left femoral vein that was misdiagnosed as having deep vein thrombosis (DVT) on initial ultrasonographic examination. The patient began to experience edema and pain in her left leg seven months previously. She was diagnosed as having DVT on initial ultrasonographic examination, but the DVT treatment that she had received for 7 months failed to improve the status of her left lower limb. Diagnoses: She subsequently underwent re-examination by means of a multimodal ultrasonographic imaging approach (regular B-mode imaging, color Doppler imaging, pulsed-wave Doppler imaging, contrast-enhanced ultrasonography), which confirmed a diagnosis of LMS. Interventions: This patient was treated successfully with surgery. Outcomes: This case demonstrates that use of multiple ultrasonographic imaging techniques can be helpful to diagnose LMS accurately. Detection of vasculature in a dilated vein filled with a heterogeneous hypoechoic substance on ultrasonography is a sign of a tumor. Lessons: The pitfall of misdiagnosing this tumor as DVT is a useful reminder. PMID:29145269

    2011-02-01

    The aim of this study was to investigate outcomes in the treatment of bilateral inguinal hernia, comparing the laparoscopic totally extraperitoneal (TEP) and open tension-free mesh repair (LICHT) approaches. We performed a prospective controlled non randomized clinical study in 128 patients with bilateral inguinal hernia over a period of 3 years. LICHT was used in 106 cases (53 patients) while TEP was employed in 150 cases (75 patients). The main outcome measurements were: recurrence rate, operating time, hospital stay and postoperative complications. There were three recurrences (2.3%): two in the LICHT group (3.8%) and one (1.3%) in the TEP group P = NS. The TEP procedure was faster than LICHT repair (48.8 ± 10.8 vs. 70.4 ± 11.2 min) P approach is an effective option for the treatment of bilateral inguinal hernia when performed by experienced surgeons.

    2017-11-01

    Conclusion: The study revealed that soccer players with osteitis pubis may have concomitant inguinal hernia, and that osteitis pubis may develop in soccer players who have undergone hernia repair. In addition, more severe osteitis pubis findings on the same side with hernia indicate that the two pathologies occur with common mechanisms. It should not be forgotten that inguinal hernia be considered in the differential diagnosis of osteitis pubis, which it may accompany. Conservative methods are mostly used in the treatment of osteitis pubis, whereas the treatment of inguinal hernia is surgery. If only one entity is diagnosed when both are present, the success of treatment will decrease.

    Full Text Available Introduction. Several laparoscopic treatment techniques were designed for improving the outcome over the last decade. The various techniques differ in their approach to the inguinal internal ring, suturing and knotting techniques, number of ports used in the procedures, and mode of dissection of the hernia sac. Patients and Surgical Technique. 90 children were subjected to surgery and they undergone two-port laparoscopic repair of inguinal hernia in children. Technique feasibility in relation to other modalities of repair was the aim of this work. 90 children including 75 males and 15 females underwent surgery. Hernia in 55 cases was right-sided and in 15 left-sided. Two patients had recurrent hernia following open hernia repair. 70 (77.7% cases were suffering unilateral hernia and 20 (22.2% patients had bilateral hernia. Out of the 20 cases 5 cases were diagnosed by laparoscope (25%. The patients’ median age was 18 months. The mean operative time for unilateral repairs was 15 to 20 minutes and bilateral was 21 to 30 minutes. There was no conversion. The complications were as follows: one case was recurrent right inguinal hernia and the second was stitch sinus. Discussion. The results confirm the safety and efficacy of two ports laparoscopic hernia repair in congenital inguinal hernia in relation to other modalities of treatment.

    The embryology and surgical anatomy of the inguinal area is presented with emphasis on embryologic and anatomic entities related to surgery. We have presented the factors, such as patent processus vaginalis and defective posterior wall of the inguinal canal, that may be responsible for the genesis of congenital inguinofemoral herniation. These, together with impaired collagen synthesis and trauma, are responsible for the formation of the acquired inguinofemoral hernia. Still, we do not have all the answers for an ideal repair. Despite the latest successes in repair, we, to paraphrase Ritsos, are awaiting the triumphant return of Theseus.

    The aim of this study was to evaluate whether a relation exists between surgical expertise and incidence of chronic postoperative inguinal pain (CPIP) after inguinal hernia repair using the Lichtenstein procedure . CPIP after inguinal hernia repair remains a major clinical problem despite many efforts to address this problem. Recently, case volume and specialisation have been found correlated to significant improvement of outcomes in other fields of surgery; to date these important factors have not been reviewed extensively enough in the context of inguinal hernia surgery. A systematic literature review was performed to identify randomised controlled trials reporting on the incidence of CPIP after the Lichtenstein procedure and including the expertise of the surgeon. Surgical expertise was subdivided into expert and non-expert. In a total of 16 studies 3086 Lichtenstein procedures were included. In the expert group the incidence of CPIP varied between 6.9 and 11.7 % versus an incidence of 18.1 and 39.4 % in the non-expert group. Due to the heterogeneity between groups no statistical significance could be demonstrated. The results of this evaluation suggest that an association between surgical expertise and CPIP is highly likely warranting further analysis in a prospectively designed study.

Needlescopic techniques have been recently used in repairing inguinal hernias, which made this type of surgery more cosmetic and less invasive. However, few reports have described its role in the treatment of incarcerated inguinal hernia. The aim of this study was to assess the feasibility and outcome of needlescopy in the treatment of incarcerated inguinal hernia in children. A total of 250 children, comprising 190 boys and 60 girls, who presented with incarcerated inguinal hernia were analyzed. Their ages ranged from 6 months to 6 years (mean age, 2 years). In 170 (68%) cases, manual reduction was successful. One hundred of these patients were subjected to definitive surgery in the same day, whereas the remaining 70 patients were subjected to needlescopy 1 to 3 days later. In 80 (32%) cases, external manual reduction was unsuccessful. These children were subjected to urgent needlescopic reduction and herniorrhaphy. The incarcerated herniae were easily reduced and the contents thoroughly inspected under direct vision. Then the hernia was repaired in the same setting. In all patients, there was no need to convert the procedure to an open approach. Immediate needlescopic herniorrhaphy in the same session was added without significant increase in operative time. The mean operative time is 10 minutes. There were no intraoperative complications. The study showed that needlescopic approach to incarcerated inguinal hernia in children is feasible, safe, easy, and preferable to the open surgery. In addition to reduction of incarcerated hernial contents under direct vision, it allows definitive treatment of hernial defect at the same time without significant increase in operative time and hospital stay.

    Inflationary observables, like the power spectrum, computed at one- and higher-order loop level seem to be plagued by large infra-red corrections. In this short note, we point out that these large infra-red corrections appear only in quantities which are not directly observable. This is in agreement with general expectations concerning infra-red effects.

    Primary leiomyosarcoma (LMS) of the vein is a rare tumor that arises from the smooth muscle cells of the vessel wall and has an extremely poor prognosis. This tumor can occur in vessels such as the inferior vena cava, great saphenous vein, femoral vein, iliac vein, popliteal vein, and renal vein; the inferior vena cava is the most common site. LMS of the femoral vein can result in edema and pain in the lower extremity; therefore, it is not easy to be differentiated from deep vein thrombosis (DVT). Moreover, virtually no studies have described the ultrasonographic features of LMS of the vein in detail. We present a case of a 55-year-old woman with LMS of the left femoral vein that was misdiagnosed as having deep vein thrombosis (DVT) on initial ultrasonographic examination. The patient began to experience edema and pain in her left leg seven months previously. She was diagnosed as having DVT on initial ultrasonographic examination, but the DVT treatment that she had received for 7 months failed to improve the status of her left lower limb. She subsequently underwent re-examination by means of a multimodal ultrasonographic imaging approach (regular B-mode imaging, color Doppler imaging, pulsed-wave Doppler imaging, contrast-enhanced ultrasonography), which confirmed a diagnosis of LMS. This patient was treated successfully with surgery. This case demonstrates that use of multiple ultrasonographic imaging techniques can be helpful to diagnose LMS accurately. Detection of vasculature in a dilated vein filled with a heterogeneous hypoechoic substance on ultrasonography is a sign of a tumor. The pitfall of misdiagnosing this tumor as DVT is a useful reminder.

    The study hypothesis was that thoracic aortic disease (TAD) is associated with a higher-than-expected prevalence of inguinal hernia. Such an association has been reported for abdominal aortic aneurysm (AAA) and hernia. Unlike AAA, TAD is not necessarily detectable with clinical examination or ultrasound, and there are no population-based screening programs for TAD. Therefore, conditions associated with TAD, such as inguinal hernia, are of particular clinical relevance. The prevalence of inguinal hernia in subjects with TAD was determined from nation-wide register data and compared to a non-TAD group (patients with isolated aortic stenosis). Groups were balanced using propensity score matching. Multivariable statistical analysis (logistic regression) was performed to identify variables independently associated with hernia. Hernia prevalence was 110 of 750 (15%) in subjects with TAD versus 29 of 301 (9.6%) in non-TAD, P=0.03. This statistically significant difference remained after propensity score matching: 21 of 159 (13%) in TAD versus 14 of 159 (8.9%) in non-TAD, PTAD, OR 1.8 (1.1 to 2.8), P=0.015. The prevalence of inguinal hernia (15%) in TAD is higher than expected in a general population and higher in TAD, compared to non-TAD. TAD is independently associated with hernia in multivariable analysis. Presence or history of hernia may be of importance in detecting TAD, and the association warrants further study. © 2014 The Authors.

    Potential risk factors for inguinal hernia in women were investigated and the relative importance of these factors was quantified. In women, symptomatic but nonpalpable hernias often remain undiagnosed. However, knowledge on this subject only concerns hernia and operation characteristics, which have been obtained by review of case series. Virtually nothing is known about risk factors for inguinal hernia. The authors performed a hospital-based case-control study of 89 female patients with an incident inguinal hernia and 176 age-matched female controls. Activity since birth with two validated questionnaires was measured and smoking habits, medical and operation history, Quetelet index (kg/m2), and history of pregnancies and deliveries were recorded. Response for cases was 81% and for controls 73%. Total physical activity was not associated with inguinal hernia (univariate odds ratio (OR) = 0.8, 95% confidence interval (CI) 0.6-1.1), but high present sports activities was associated with less inguinal hernia (multivariate OR = 0.2, 95% CI 0.1-0.7). Obesity (Quetelet index > 30) was also protective for inguinal hernia (OR = 0.2, 95% CI 0.04-1.0). Independent risk factors were positive family history (OR = 4.3, 95% CI 1.9-9.7) and obstipation (OR = 2.5, 95% CI 1.0-6.7). In particular, smoking, appendectomy, other abdominal operations, and multiple deliveries were not associated with inguinal hernia in females. The protective effect of present sports activity may be explained by optimizing the resistance of the abdominal musculature protecting the relatively small inguinal weak spot in the female. The individual predisposition for inguinal hernia may be quantified by these risk factors, and, with this in mind, the authors advise that further evaluation might be needed for the patient with unexplained inguinal pain.

    AIM: To study the safety, effectiveness and diagnostic value of transvenous forceps biopsy of the liver in 54 patients with coagulopathy, gross ascites or morbid obesity and suspected liver disease in whom percutaneous liver biopsy was contraindicated. MATERIAL AND METHODS: Forceps biopsy of the liver via the femoral vein was attempted in 54 adult patients with advanced liver disease of unknown aetiology who had coagulation disorders (41 cases), gross ascites (11 cases) or morbid obesity (two cases). In each patient two to six biopsies (average four) were taken using a radial jaw forceps inserted via the right or left femoral vein. RESULTS: The procedure was successful in 53 cases. Hepatic vein catheterization failed in one patient. Adequate liver tissue for diagnosis was obtained in 84% of cases. One patient developed delayed haemorrhage at 12 h from a capsular leak that was undetected during the biopsy procedure. This patient required blood transfusions and laparotomy to control bleeding. There were no deaths in the 53 patients studied. Transient minor chest and shoulder pain was encountered during sheath insertion into a hepatic vein in 23 patients. Three patients developed a femoral vein haematoma, which resolved with conservative treatment. CONCLUSION: Transvenous liver biopsy via the femoral vein is another safe, effective, simple alternative technique of biopsy when the percutaneous route is contraindicated

    To describe transumbilical laparoscopic herniorrhaphy after unsuccessful attempted manual reduction of incarcerated inguinal hernias in infants and children. In our two hospitals, two-trocar transumbilical endoscopic surgery (TUES) is the standard technique used to repair incarcerated inguinal hernias in infants and children. Seventeen patients (aged 8months to 2.5years; median, 15months; 15 boys, 2 girls) with incarcerated inguinal hernias underwent urgent laparoscopy after unsuccessful attempted manual reduction. Two 3- or 5-mm trocars were inserted into the abdomen through two intraumbilical incisions, under laparoscopic guidance. The hernia was reduced by combined external manual pressure and internal pulling with bowel forceps. After inspection of the bowel, a round needle with a 2-0 nonabsorbable suture was introduced into the peritoneal cavity through the anterior abdominal wall near the internal inguinal ring. The hernial orifice was closed with an extraperitoneal purse-string suture around the internal inguinal ring, and tied with an intraperitoneal knot. A similar procedure was performed on the contralateral side if the processus vaginalis was patent. The TUES procedure was successful in all patients. No conversions to open surgery were required. The mean operating time was 30min (range, 25-40min). All patients were discharged on the second postoperative day. No complications such as postoperative bleeding, hydrocele, or scrotal edema were observed. The mean follow-up period was 15months. No cases of testicular atrophy, hypotrophy, or hernia recurrence were reported. Our preliminary experience with using TUES for the treatment of incarcerated inguinal hernias in infants and children had satisfactory outcomes. This technique appeared to be safe, effective, and reliable, and had excellent cosmetic results. Published by Elsevier Inc.

    Objective: To investigate the feasibility of interventional catheterization with bilateral femoral vein approaches for performing the thrombolytic treatment of acute deep venous thrombosis of left lower extremity. Methods: Antegrade puncturing into the left femoral vein was carried out in eighteen patients with acute deep vein thrombosis in the left lower extremity after left iliac-femoral vein catheterization via the right femoral vein or the right jugular vein access failed. When the puncturing of the left femoral vein was successfully done and was confirmed by angiography, the guide wire was inserted into the inferior vena cava and was pulled out through the right femoral vein or right jugular vein, and a wire track was thus established. Then, retrograde insertion of the catheter was conducted along the wire from the right to the left until the catheter was placed into the left iliac-femoral vein for thrombolysis. Results: Of 18 cases,successful puncturing into the left femoral vein was achieved in 16, and an effective wire track was established between the left and right femoral veins, based on which the catheter was smoothly inserted into the left iliac-femoral vein via the right femoral vein or jugular vein. Catheter thrombolysis was employed for 3 to 14 days, the thrombus was completely dissolved and the lower extremity swelling subsided. During the course of thrombolysis, no obvious congestion or hematoma occurred at the puncturing site of the left femoral vein. Conclusion: For patients with deep vein thrombosis of left lower extremity, when left iliac-femoral vein catheterization via the right femoral vein or the right jugular vein access failed, the establishment of wire track by using bilateral femoral vein approaches for further catheterization of left iliac-femoral vein and subsequent thrombolysis is feasible in clinical practice. This technique is safe and minimally-invasive with higher success rate. (authors)

    Full Text Available Background: Complicated inguinal hernias pose a threat to the life of the child as well as increase the morbidity associated with management of an otherwise straightforward condition. The aim of this study was to determine the presentation, treatment and management outcome of complicated inguinal hernias in children. Materials and Methods: A retrospective study of all children 15 years and less managed for complicated inguinal hernia between 2002 and 2010. Data obtained included demographic characteristics, presentation, operative findings and outcome. Results: Complicated hernia rate was 13.9%.There were 41 children, 38 boys (92.7% and 3 girls. Ages ranged between 4 days and 15 years (Median = 90days. Most were infants (48.8%, n = 20 and neonates accounted for 19.5% (n = 8. Median duration of symptoms prior to presentation was 18 h (range = 2-96 h. Seven patients had been scheduled for elective surgery. Hernia was right sided in 68.3% (n = 28. Symptoms included vomiting (68.3%, abdominal distension (34.1% and constipation (4.9%; one patient presented with seizures. In 19 (46.3% patients hernia was reducible while 22(53.7% had emergency surgery. Associated anomalies included undescended testis (12.2%, umbilical hernia (14.6%. Intestinal resection rate was 7.3% and testicular gangrene occurred in 14.6%. Mean duration of surgery was 60.3 ± 26.7 min. Wound infection occurred in six patients (14.6%. Overall complication rate was 24.4%, 30% in infants. The mortality rate was 2.4% (n = 1. Conclusions: Morbidity associated with complicated inguinal hernia is high in neonates and infants. Delayed presentation is common in our setting. Educating the parents as well as primary care physicians on the need for early presentation is necessary.

    Inguinal lymph node metastasis from adenocarcinoma arising at a colostomy site is extremely rare, and the significance of surgical resection for metastatic inguinal lymph nodes has not been established. An 82-year-old woman who had undergone abdominoperineal resection 27 years earlier was admitted to our hospital complaining of bleeding from a colostomy. Physical examination revealed that a tumor at the colostomy site directly invaded into the peristomal skin, and that a left inguinal lymph node was firm and swollen. Positron emission tomography/computed tomography scan demonstrated accumulation of (18)F-fluorodeoxy glucose into both the colostomy tumor and the left swollen inguinal lymph node, while there was no evidence of metastasis to liver or lungs. She underwent open left hemicolectomy with wide local resection of the colostomy, and dissection of left inguinal lymph nodes. Histological diagnosis was a moderately differentiated adenocarcinoma that directly invaded into the surrounding skin and metastasized to the left inguinal lymph node. The patient has been followed up for >5 years without any sign of recurrence. In general, inguinal lymph node metastasis from colorectal cancers is regarded as a systemic disease with a poor prognosis, and so systemic chemotherapy and radiotherapy, but not surgical lymph node dissection, are recommended. Considering the lymphatic drainage route in the present case, inguinal lymph node metastasis does not represent a systemic disease but rather a sentinel nodal metastasis from adenocarcinoma at a colostomy site. Surgical dissection of metastatic inguinal lymph nodes should be considered to enable a favorable prognosis in the absence of distant metastasis to other organs. © The Author 2014.

    Full Text Available Conventional meta-analyses have shown inconsistent results for the efficacy of various treatments of varicoceles. Therefore, we performed a multiple-treatment meta-analysis to assess the effectiveness and safety of 10 methods of varicocelectomy and embolization/sclerotherapy. We systematically reviewed 35 randomized controlled trials and observational studies, from 1966 to August 5, 2013, which compared any of the following treatments for varococeles: laparoscopic, retroperitoneal, open inguinal and subinguinal varicocelectomy, microsurgical subinguinal and inguinal varicocelectomy, percutaneous venous embolization, Tauber antegrade sclerotherapy, retrograde sclerotherapy and expectant therapy (no treatment. Inguinal and subinguinal microsurgery, open inguinal, laparoscopic varicocelectomy showed a significant advantage over expectant therapy in terms of pregnancy rates (odds ratio (OR: 3.48, 2.68, 2.92 and 2.90, respectively. Compared with retroperitoneal open surgery, inguinal microsurgery showed an improvement of sperm density (mean difference (MD: 10.60, 95% confidence interval (CI: 1.92-19.60 and sperm motility (MD: 9.09, 95% CI: 4.88-13.30. Subinguinal and inguinal microsurgery outperformed retroperitoneal open surgery in terms of recurrence (OR: 0.05, 0.06 respectively. Tauber antegrade sclerotherapy and subinguinal microsurgery were associated with the lowest risk of hydrocele formation. The odds of overall complication, compared with retroperitoneal open varicocelectomy, were lowest for inguinal microsurgery (OR = 0.07, 95% CI: 0.02-0.19, followed by subinguinal microsurgery (OR = 0.09, 95% CI: 0.02-0.19. Inguinal and subinguinal micro-varicocelectomy had the highest pregnancy rates, significant increases in sperm parameters, with low odds of complication. These results warrant additional properly conducted randomized controlled clinical studies with larger sample sizes.

    The selection of a laparoscopic approach for inguinal hernias varies among surgeons. It is unclear what is being done in actual practice. The purpose of this study was to report practice patterns for treatment of inguinal hernias among Quebec surgeons, and to identify factors that may be associated with the choice of operative approach. We studied a population-based cohort of patients who underwent an inguinal hernia repair between 2007 and 2011 in Quebec, Canada. A generalized linear model was used to identify predictors associated with the selection of a laparoscopic approach. 49,657 inguinal hernias were repaired by 478 surgeons. Laparoscopic inguinal hernia repair (LIHR) was used in 8 % of all cases. LIHR was used to repair 28 % of bilateral hernias, 10 % of recurrent hernias, 6 % of unilateral hernias, and 4 % of incarcerated hernias. 268 (56 %) surgeons did not perform any laparoscopic repairs, and 11 (2 %) surgeons performed more than 100 repairs. These 11 surgeons performed 61 % of all laparoscopic cases. Patient factors significantly associated with having LIHR included younger age, fewer comorbidities, bilateral hernias, and recurrent hernias. An open approach is favored for all clinical scenarios, even for situations where published guidelines recommend a laparoscopic approach. Surgeons remain divided on the best technique for inguinal hernia repair: while more than half never perform LIHR, the small proportion who perform many use the technique for a large proportion of their cases. There appears to be a gap between the best practices put forth in guidelines and what surgeons are doing in actual practice. Identification of barriers to the broader uptake of LIHR may help inform the design of educational programs to train those who have the desire to offer this technique for certain cases, and have the volume to overcome the learning curve.

    Human aortocoronary vein grafts fail due to accelerated occlusive disease. The possibility that this is related to cellular hyperplasia was investigated in a rabbit model where kinetics of vein graft thickening, endothelial (EC) repair, and smooth muscle cell (SMC) proliferation were measured from 2 days to 24 weeks after implanting jugular vein segments in the carotid artery. Immediately after graft placement focal EC denudation was observed. These defects were repaired within 1 week and did not recur. By 4 weeks intimal area had increased 30 fold from 0.028 +/- 0.004 to 0.705 +/- 0.021 mm 2 , and a 24 weeks was 0.93 +/- 0.21 mm 2 . This response did not produce a reduction in graft lumen area. EC and SMC thymidine-labeling index were measured by en face and cross-section autoradiography after injection of 3 H-thymidine and perfusion fixation. Despite rapid EC surface repair EC labeling index remained elevated and only returned to normal levels at 12 weeks; SMC labeling was 10 fold greater than baseline even at 24 weeks (0.22% vs 0.02%). SMC mass demonstrated morphometrically increased between 2 and 12 weeks. Intimal thickening in vein grafts is due to SMC proliferation and develops after the EC layer has been restored. In contrast, intimal SMC proliferate in damaged arteries when the EC layer is absent and cease when the EC layer is regenerated

    Full Text Available Purpose: Surgeons performing an ilioinguinal exposure for acetabular fracture surgery need to be aware of aberrant findings such as inguinal hernias and spermatic cord lesions. The purpose of this study is to report these occurrences in a clinical series of adult males undergoing acetabular fracture fixation and a series of adult male cadavers. The secondary aim is to characterize these abnormalities to aid surgeons in detecting these abnormalities preoperatively and coordinating a surgical plan with a general surgeon.Methods: Clinical study- Retrospective review of treated acetabular fractures through an ilioinguinal approach. Incidence of inguinal canal and spermatic cord abnormalities requiring general surgery consultation were identified. Corresponding CT scans were reviewed and radiographic characteristics of the spermatic cord abnormalities and/or hernias were noted.Cadaveric study- 18 male cadavers dissected bilaterally using an ilioinguinal exposure. The inguinal canal and the contents of the spermatic cord were identified and characterized.Results: Clinical Study- 5.7% (5/87 of patients had spermatic cord lesion and/or inguinal hernia requiring general surgical intervention. Preoperative pelvic CT scan review identified abnormalities noted intraoperatively in four of the five patients. Cord lipomas visualized as enlargements of the spermatic cord with homogeneous density. Hernias visualized as enlarged spermatic cords with heterogeneous density. Cadaver Study- 31% (11/36 of cadavers studied had spermatic cord and/or inguinal canal abnormalities. Average cord diameter in those with abnormalities was 24.9 mm (15-28 compared to 16 mm (11-22 in normal cords, which was statistically significant.Conclusion: The clinical and cadaveric findings emphasize the importance of understanding inguinal abnormalities and the value of detecting them preoperatively. The preoperative pelvic CT scans were highly sensitive in detecting inguinal abnormalities.

    Infra-red radiations find wide application in industrial processes as heating, drying, stoving and forming. The results are often far better than those from the other techniques: convection oven, gas IR etc ... They come from the electric IR specific advantages: energy direct transmission, emitter and product spectral coupling, possible selectivity. That is the case in the Textile Industry, where experiments showed that infra-red process heating could be efficient for colour fixation on fabrics. Shorter production cycles and energy saving are the main results

    BACKGROUND AND AIMS: Hernia formation is associated with alterations of collagen metabolism. Collagen synthesis and degradation cause a systemic release of products, which are measurable in serum. Recently, we reported changes in type V and IV collagen metabolisms in patients with inguinal...... elective cholecystectomy served as controls (n = 10). Whole venous blood was collected 35-55 months after operation. Biomarkers for type V collagen synthesis (Pro-C5) and degradation (C5M) and those for type IV collagen synthesis (P4NP) and degradation (C4M2) were measured by a solid-phase competitive...... assay. RESULTS: The turnover of type V collagen (Pro-C5/C5M) was slightly higher postoperatively when compared to preoperatively in the inguinal hernia group (P = 0.034). In addition, the results revealed a postoperatively lower type V collagen turnover level in the inguinal hernia group compared...

    In the Netherlands, approximately 30,000 inguinal hernia repairs are performed yearly. At least 15% are for recurrence. New procedures are being introduced creating discussion on which technique is the best. Currently it is not possible to choose on evidence alone because of the long follow-up that is needed. In 1996 an inventory was taken of all inguinal hernia repairs that were performed in the Amsterdam region (9 hospitals). These results were compared with the results from a similar study performed in 1994. Major changes in treatment strategy were noted. The Bassini repair was replaced by Shouldice and Lichtenstein techniques. There was a significant increase in the use of prostheses for both primary and recurrent inguinal hernias. There was no significant decrease in the percentage of operations performed for recurrent hernia from 19.5% to 16.8%. However, there was a significant decrease in operations performed for early recurrences (5.1%-3.4%) (p = 0.05). These results suggest that the Shouldice and Lichtenstein repairs may be superior to the Bassini repair in terms of early hernia recurrence.

    Full Text Available Abstract Background Metastatic hernia sac tumor from biliary malignancy is extremely rare with only one such case previously reported. We herein report an additional case of extrahepatic cholangiocarcinoma presenting as a hernia sac tumor. Case presentation A 78-year-old man presented with an irreducible right inguinal hernia associated with a firm tumor, 2.0 cm in diameter. A computed tomography scan demonstrated a soft tissue density mass with heterogeneous enhancement within the right inguinal canal. The patient underwent a hernia repair and the hernia sac tumor was resected. Histological examination of the tumor revealed a metastatic adenocarcinoma suggesting the tumor was of pancreato-biliary origin. Further investigation using imaging studies disclosed a primary tumor in the upper bile duct. The patient died of the disease nine months after the resection. Conclusion Hernia sac tumors should be considered when an irreducible, growing mass appears within an inguinal hernia. Computed tomography may be useful for the early detection of hernia sac tumors from undiagnosed intra-abdominal malignancies.

    To monitor and improve nation-wide surgical outcome after groin hernia repair based on scientific evidence-based surgical strategies for the national and international surgical community. Patients ≥18 years operated for groin hernia. Type and size of hernia, primary or recurrent, type of surgical repair procedure, mesh and mesh fixation methods. According to the Danish National Health Act, surgeons are obliged to register all hernia repairs immediately after surgery (3 minute registration time). All institutions have continuous access to their own data stratified on individual surgeons. Registrations are based on a closed, protected Internet system requiring personal codes also identifying the operating institution. A national steering committee consisting of 13 voluntary and dedicated surgeons, 11 of whom are unpaid, handles the medical management of the database. The Danish Inguinal Hernia Database comprises intraoperative data from >130,000 repairs (May 2015). A total of 49 peer-reviewed national and international publications have been published from the database (June 2015). The Danish Inguinal Hernia Database is fully active monitoring surgical quality and contributes to the national and international surgical society to improve outcome after groin hernia repair.

  15. Unusual metachronous isolated inguinal lymph node metastasis from adenocarcinoma of the sigmoid colon

    Full Text Available Abstract This study aimed to describe an unusual case of metachronous isolated inguinal lymph nodes metastasis from sigmoid carcinoma. A 62-year-old man was referred to our department because of an obstructing sigmoid carcinoma. Colonoscopy showed the obstructing lesion at 30 cm from the anal verge and abdominal CT revealed a sigmoid lesion infiltrating the left lateral abdominal wall. The patient underwent a colonic resection extended to the abdominal wall. Histology showed an adenocarcinoma of the colon infiltrating the abdominal wall with iuxtacolic nodal involvement. Thirty three months after surgery abdominal CT and PET scan revealed a metastatic left inguinal lymph node involvement. The metastatic lymph node was found strictly adherent to the left iliac-femoral artery and encompassing the origin of the left inferior epigastric artery. Histology showed a metachronous nodal metastasis from colonic adenocarcinoma. Despite metastastic involvement of inguinal lymph node from rectal cancer is a rare but well known clinical entity, to the best of our knowledge, this is the first report of inguinal metastasis from a carcinoma of the left colon. Literature review shows only three other similar reported cases: two cases of inguinal metastasis secondary to adenocarcinoma of the cecum and one case of axillary metastasis from left colonic carcinoma. A metastatic pathway through superficial abdominal wall lymphatic vessels could be possible through the route along the left inferior epigastric artery. The solitary inguinal nodal involvement from rectal carcinoma could have a more favorable prognosis. In the case of nodal metastasis to the body surface lymph nodes from colonic carcinoma, following the small number of such cases reported in the literature, no definitive conclusions can be drawn.

    Retroperitoneal liposarcomas usually present as painless, slow-growing abdominal masses. When masses grow large enough to compress surrounding structures, symptoms may occur. Retroperitoneal liposarcoma clinically manifesting as inguinal hernia is a very rare entity; only 11 cases have been reported. Herein, we present radiographic features of a 37-year-old male with a painless palpable mass in the right groin that was identified as dedifferentiated retroperitoneal liposarcoma herniated through the right inguinal canal.

  18. An Incarcerated Colon Inguinal Hernia That Perforated into the Scrotum and Exhibited an Air-Fluid Level

    2015-01-01

    Full Text Available There are few reports of a transverse colon inguinal hernia; furthermore, an inguinal hernia perforating the scrotum is rare. Here we report the case of a 79-year-old man who died after developing an incarcerated colon inguinal hernia that perforated the scrotum and exhibited an air-fluid level. The patient was referred to our hospital in November 2011 with a complaint of inability to move. Physical examination revealed an abnormally enlarged left scrotum and cold extremities. He reported a history of gastric cancer that was surgically treated more than 30 years ago. His white blood cell count and C-reactive protein level were elevated. Abdominal and inguinal computed tomography revealed that his transverse colon was incarcerated in the left inguinal canal. Free air and air-fluid level were observed around the transverse colon, suggestive of a perforation. The patient and his family refused any surgical intervention; therefore, he was treated with sultamicillin tosilate hydrate and cefotiam hydrochloride. However, he succumbed to panperitonitis 19 days after admission. The findings from this case indicate that the transverse colon can perforate into an inguinal hernia sac.

    The authors report some mathematical aspects of a recent solution of the infra-red catastrophe in quantum electro-dynamics. A principal result is that the coordinate space Feynman function can be separated into two factors the first of which is a unitary operator in photon space representing the classical electro-magnetic contribution to the amplitude, and the second of which is a residual factor representing the quantum fluctuation about the classical contribution. The main objectives were to verify: (i) the residual factor is free of infra-red divergences, and (ii) the dominant part of the singularity of the residual factor on the positive-α Landau surface has the same analytic form as it would have if the photons were massive.

    Purpose: To study the distribution of gross inguinal lymph node metastasis and, in particular, its correlation with major pelvic bony structures on a simulation film. Methods and Materials: Thirty-seven cases of low pelvic tumors having gross inguinal lymph node metastasis that were treated with radiation therapy between November 1987 and December 1992 were segregated for study. The patient's nodes were palpated and marked with lead wire before the simulation film was taken. The geometric center of the usually round or elliptical node on the film was assumed to be the origin of the previously uninfested node. A total of 84 such labeled nodes was obtained from these 37 cases. These centers were transferred to and mapped collectively on a new simulation film showing major pelvic bony structures of left hemipelvis and upper femur. Results: Distribution of gross inguinal lymph nodes was found confined to the following area, as related to major pelvic bony structure: laterally, just abutting the tangential line that passes through lateral border of the femoral head; medially: 3 cm away from the body's midline axis; superiorly: 1 cm below the line that joins both upper borders of the femoral head; inferiorly: 2.5 cm below the low borders of ischial tuberosity. According to this rectangular boundary, three nodes were out of field, nine nodes near the border less than 1 cm margin. This area adequately covered 86% (72 of 84) of the studied nodes. Conclusion: Distribution study is important in determining the treatment margin. In general, an additional 1-2 cm beyond the area described above is the recommended treatment margin for elective inguinal lymph nodes irradiation with high confidence level of coverage.

  3. Assessing and optimizing infra-sound networks to monitor volcanic eruptions

    2016-01-01

    Understanding infra-sound signals is essential to monitor compliance with the Comprehensive Nuclear-Test ban Treaty, and also to demonstrate the potential of the global monitoring infra-sound network for civil and scientific applications. The main objective of this thesis is to develop a robust tool to estimate and optimize the performance of any infra-sound network to monitor explosive sources such as volcanic eruptions. Unlike previous studies, the developed method has the advantage to consider realistic atmospheric specifications along the propagation path, source frequency and noise levels at the stations. It allows to predict the attenuation and the minimum detectable source amplitude. By simulating the performances of any infra-sound networks, it is then possible to define the optimal configuration of the network to monitor a specific region, during a given period. When carefully adding a station to the existing network, performance can be improved by a factor of 2. However, it is not always possible to complete the network. A good knowledge of detection capabilities at large distances is thus essential. To provide a more realistic picture of the performance, we integrate the atmospheric longitudinal variability along the infra-sound propagation path in our simulations. This thesis also contributes in providing a confidence index taking into account the uncertainties related to propagation and atmospheric models. At high frequencies, the error can reach 40 dB. Volcanic eruptions are natural, powerful and valuable calibrating sources of infra-sound, worldwide detected. In this study, the well instrumented volcanoes Yasur, in Vanuatu, and Etna, in Italy, offer a unique opportunity to validate our attenuation model. In particular, accurate comparisons between near-field recordings and far-field detections of these volcanoes have helped to highlight the potential of our simulation tool to remotely monitor volcanoes. Such work could significantly help to prevent

    Full Text Available PURPOSE: Our previous studies demonstrated structural and quantitative age-related changes of the elastic fibers in transversalis fascia, which may play a role in inguinal hernia formation. To verify whether there were differences in the extracellular matrix between direct and indirect inguinal hernia, we studied the amount of collagen and elastic fibers in the transversalis fascia of 36 male patients with indirect inguinal hernia and 21 with direct inguinal hernia. MATERIAL AND METHODS: Transversalis fascia fragments were obtained during surgical intervention and underwent histological quantitative analysis of collagen by colorimetry and analysis of elastic fibers by histomorphometry. RESULTS: We demonstrated significantly lower amounts of collagen and higher amounts of elastic fibers in transversalis fascia from patients with direct inguinal hernia compared to indirect inguinal hernia patients. The transversalis fascia from direct inguinal hernia patients showed structural changes of the mature and elaunin elastic fibers, which are responsible for elasticity, and lower density of oxytalan elastic fibers, which are responsible for resistance. These changes promoted loss of resiliency of the transversalis fascia. CONCLUSION: These results improve our understanding of the participation of the extracellular matrix in the genesis of direct inguinal hernia, suggesting a relationship with genetic defects of the elastic fiber and collagen synthesis.OBJETIVO: Estudos prévios nossos demonstraram alterações estruturais e quantitativas de fibras elásticas na fascia transversal com o envelhecimento, tendo papel na gênese da hérnia inguinal.

    Nausea and vomiting are among the most frequent complications following anesthesia and surgery. Due to anesthesia seems to be primarily responsible for post operative nausea and vomiting (PONV) in Day Surgery facilities, the aim of the study is to evaluate how different methods of anesthesia could modify the onset of postoperative nausea and vomiting in a population of patients undergoing inguinal hernia repair. Ninehundredten patients, aged between 18 and 87 years, underwent open inguinal hernia repair. The PONV risk has been assessed according to Apfel Score. Local anesthetic infiltration, performed by the surgeon in any cases, has been supported by and analgo-sedation with Remifentanil in 740 patients; Fentanyl was used in 96 cases and the last 74 underwent deep sedation with Propofol . Among the 910 patients who underwent inguinal hernia repair, PONV occurred in 68 patients (7.5%). Among patients presenting PONV, 29 received Remifentanil, whereas 39 received Fentanyl. In the group of patients receiving Propofol, no one presented PONV. This difference is statistically significant (p < .01). Moreover, only 50 patients of the total sample received antiemetic prophylaxis, and amongst these, PONV occurred in 3 subjects. Compared to Remifentanil, Fentanyl has a major influence in causing PONV. Nonetheless, an appropriate antiemetic prophylaxis can significantly reduce this undesirable complication. Key words: Day Surgery, Fentanyl, Inguinal, Hernia repair, Nausea, Vomiting.

    2011-01-01

    Full Text Available Introduction. Primary venous tumours are a rare cause of deep vein thrombosis. The authors present a case where the definitive diagnosis was delayed by inconclusive complementary imaging. Clinical Case. A thirty-seven-year-old female presented with an iliofemoral venous thrombosis of the right lower limb. The patient had presented with an episode of femoral-popliteal vein thrombosis five months before and was currently under anticoagulation. Phlegmasia alba dolens installed progressively, as thrombus rapidly extended to the inferior vena cava despite systemic thrombolysis and anticoagulation. Diagnostic imaging failed to identify the underlying aetiology of the deep vein thrombosis. The definitive diagnosis of primary venous leiomyosarcoma was reached by a subcutaneous abdominal wall nodule biopsy. Conclusion. Primary venous leiomyosarcoma of the iliac vein is a rare cause of deep vein thrombosis, which must be considered in young patients with recurrent or refractory to treatment deep vein thrombosis.

    To demonstrate the feasibility of endoscopic extraperitoneal single site (EESS) inguinal hernia repair and compare it outcomes with the conventional totally extraperitoneal (TEP) technique. TEP inguinal hernia repair is a widely accepted alternative to conventional open technique with several perioperative advantages. Transumbilical laparoendoscopic singlesite surgery (LESS) is an emerging approach and has been reported for a number of surgical procedures with superior aesthetic results but other advantages need to be proven. Thirty-eight uncomplicated inguinal hernias were repaired by EESS approach between January 2010 and January 2011. All procedures were performed through a 25 cm infraumbilical incision using the Alexis wound retractor attached to a surgical glove and three trocars. Body mass index, age, operative time, blood loss, complications, conversion rate, analgesia requirement, hospital stay, return to normal activities and patient satisfaction with aesthetic results were analysed and compared with the last 38 matched-pair group of patients who underwent a conventional TEP inguinal hernia repair by the same surgeon. All procedures were performed successfully with no conversion. In both unilateral and bilateral EESS inguinal repairs, the mean operative time was longer than conventional TEP (55± 20 vs. 40± 15 min, P = 0.049 and 70± 15 vs. 55± 10 min, P = 0.014). Aesthetic result was superior in the EESS group (2.88± 0.43 vs. 2.79± 0.51, P = 0.042). There was no difference between the two approaches regarding blood loss, complications, hospital stay, time until returns to normal activities and analgesic requirement. EESS inguinal hernia repair is safe and effective, with superior cosmetic results in the treatment of uncomplicated inguinal hernias. Other advantages of this new technique still need to be proven.

    This study was done to compare antegrade punctures with a retrograde puncture technique for infrainguinal angioplasty. A group of 100 consecutive patients (71 men, 29 women) were randomized for antegrade puncture or retrograde puncture of the common femoral artery. Following retrograde puncture the guidewire was 'turned' and placed into the superficial femoral artery. The time for gaining access, screening time, radiation dose, patient height, weight and complications were recorded. All patients were reviewed the day after the procedure and within 3 months. Data from 46 patients (34 males and 12 females) in the retrograde group and 44 (28 males and 16 females) in the antegrade group were available for analysis. Mean procedure time,screening time, radiation dose, height and weight were 8.3 minutes(range 3-22), 2.1 minutes (0.3-6.5), 7950 mGy cm -2 (820-71250), 169 cm (149-204) and 79 kg (32-108) for retrograde puncture and 8 min (2-60), 0.7 min (0.0-3.2), 1069 mGycm -2 (0-15400), 169 cm (152-186) and 75 kg (39-125) for antegrade punctures, respectively. An average of 1.2 (1-2) punctures was required for retrograde and 1.75 (1-8) for antegrade. Seven small hematomas occurred with antegrade and three for retrograde puncture.Retrograde puncture is technically easier with a tendency to fewer complications but results in a higher radiation dose. This technique should be used in difficult patients at high risk of haematoma formation

    The use of local anaesthetic for open inguinal hernia surgery has long been restricted to specialist centres. This study aimed to compare the efficacy of spinal anaesthesia and sub-fascial local anaesthetic (LA) for performing open hernia repair and at the same time provide better post op pain relief and early mobilization. Methods: In this randomized clinical trial, 62 male patients aged 16-72 were randomly allocated to two groups. Group A received mixture of 20ml 0.5% bupivacain, 20ml 2% lignocaine with adrenaline, 20ml normal saline (N/S), 3 ml NaHCO/sub 3/ sub-fascially for Local anaesthetic (LA) inguinal field block, while Group B received Spinal Anaesthesia (SA) with 0.5% Bupivacaine. Comparison was made in terms of Visual Analogue Score (VAS) recorded intra-operatively at 0 and 30 minutes and post operatively at 2, 4 and 12 hours at rest and on movement. Need for rescue analgesia and total analgesic consumption in both groups were calculated. Interval to pain free ambulation as well as procedural and anaesthesia related complications were compared. Results: Mean VAS in the intraoperative period were significantly high in Group A (p-value 0.011) at the start of operation and at 30 minutes (p-value <0.001). However, it did not correlate with patient satisfaction as 90% of patients in Group A successfully underwent the procedure without need for supplemental analgesia. VAS scores at rest and on movement/cough were comparable in the post op period at 2, 4 and 12 hours in both groups. Interval to pain free ambulation was significantly low in Group A (p-value 0.0012). Conclusion: Sub facial LA inguinal field block provides effective anaesthesia with optimum post op analgesia, prompt recovery and fewer systemic side effects compared to SA and can safely be used for routine open inguinal hernia surgery.

    In an earlier interview study, we found that more men with familial schizophrenia had undergone inguinal hernia operation, than men with sporadic schizophrenia. However, there are no other studies published specifically on inguinal hernia and schizophrenia. Therefore, the aim of this study was to carry out a Swedish register-based cohort study on the association between inguinal hernia and schizophrenia or related psychosis. Data from the Total Population- and Medical Birth-Registers were used to create a cohort of all individuals born in Sweden 1987-1999 (n=1 406 168). The cohort individuals were linked with the In- and Out-patient Registers and followed from birth to 2015 to identify onset of schizophrenia, schizoaffective disorder and inguinal hernia. Cox proportional hazards regression models were used to assess the association between inguinal hernia before age 13 and risk of developing schizophrenia or schizoaffective disorder during a follow-up from age 13. Inguinal hernia before age 13 was identified in 21 095 individuals, and during the follow-up in total 1314 individuals developed schizophrenia or schizoaffective disorder. The risk of schizophrenia or schizoaffective disorder was higher among individuals with inguinal hernia before age 13, than among individuals without such a diagnosis, especially among the men [adjusted hazard ratio (95% confidence interval); all: 1.44 (1.01-2.06), p=0.0452, men: 1.46 (1.01-2.12), p=0.0460, women: 0.56 (0.14-2.27), p=0.4173]. This study shows that early-onset inguinal hernia is associated with increased risk of developing schizophrenia or schizoaffective disorder, especially in men. Such an association may point to a common biological basis for the development of inguinal hernia and schizophrenia or related psychosis.

This randomized placebo-controlled trial investigated the efficacy of a capsaicin 8% cutaneous patch in the treatment of severe persistent inguinal...... postherniorrhaphy pain. METHODS: Forty-six patients with persistent inguinal postherniorrhaphy pain were randomized to receive either a capsaicin 8% patch or a placebo patch. Pain intensity (Numerical Rating Scale [NRS 0-10]) was evaluated under standardized conditions (at rest, during movement, and during pressure....... The primary outcome was comparisons of summed pain intensity differences (SPIDs) between capsaicin and placebo treatments at 1, 2 and 3 months after patch application (significance level P placebo treatments, was observed at 1 month after...

    The DRG system in Germany was introduced to improve and at the same time simplify the reimbursement of costs in German hospitals. Cost effectiveness and economic efficiency were the declared goals. Structural changes and increased competition among different hospitals were the consequences. The effect on the qualitiy of patient care has been discussed with some concern. Furthermore, doubts have been expressed about the correct representation of the various diagnoses and treatments in the coding system and the financial revenue. Inguinal hernia repair serves as an example to illustrate some common problems with the reimbursement in the DRG system. Virtual patients were grouped using a "Web Grouper" and analysed using the cost accounting from the G-DRG-Browser of the InEK. Additionally, the reimbursement for ambulant hernia repair was estimated. The DRG coding did not differentiate the various operative procedures for inguinal hernia repair. They all generated the same revenues. For example, the increased costs for bilateral inguinal hernia repair are not represented in the payment. Furthermore, no difference is made between primary and recurrent inguinal hernia. In the case of a short-term hospital stay, part of the revenue is retained. In the case of ambulatory treatment of inguinal hernia, the reimbursement is by far not a real compensation for the actual costs. The ideal patient in the DRG system suffers from a primary inguinal hernia, undergoes an open hernia repair without mesh, and remains for 2-3 days in hospital. Minimally invasive procedures, repair of bilateral inguinal hernia and ambulant operation are by far less profitable--if at all. The current revenues for inguinal hernia repair require improvement and adjustment to reality in order to accomplish the goals which the DRG system in Germany aims at.

    Inguinal hernia is one of the most common surgical problem presenting to the surgical OPD. Surgery is the mainstay of treatment for inguinal hernia today. Surgery for inguinal hernia has undergone a great evolution over a period of several centuries. Lichenstein's tension free hernioplasty is the one of the first surgeries taught to a surgical resident. The main aim of surgeries in this era is to give the best possible results with the least possible pain, scar and time. This has given rise to so many modifications to the classical Lichenstein's procedure and also to laparoscopic hernioplasty. Pain after inguinal hernia surgery is found to be debilitating and altering the quality of life in several patients, which has been attributed to the traumatic fixation of the mesh with sutures. This has paved way to the development of various atraumatic methods of fixation, tissue glue is one such development. Hence this study, to compare traumatic and atraumatic methods of mesh fixation in inguinal hernia repair. The aim of this study was to compare suture fixation versus tissue glue fixation of the mesh in inguinal hernia repair. Primary objective was to compare the immediate and chronic post-operative pain. Secondary objective was to compare the time taken for the procedure by the two methods in use and also to compare the presence of any complications. and methodology: This study was done in the General Surgery department of XXX hospital, medical college and research centre, kattangulathur after Ethics committee clearance. It is a single blinded study. The study was done on 51 patients consenting for the study and meeting the inclusion criterias from the period of March 2016 to August 2017 out of which 26 were selected for glue mesh fixation and 25 for suture mesh fixation according to simple randomization. The suture group patients underwent classical Lichenstein's tension free hernioplasty and the glue group underwent Lichenstein's hernioplasty with glue where dots of

    Pelvic vein incompetence is common in patients with atypical varicose veins, contributing to their recurrence after surgery. Therefore, refluxing pelvic veins should be identified and treated. We present our experience with pelvic vein embolisation in patients presenting with varicose veins. Patients presenting with varicose veins with a duplex-proven contribution from perivulval veins undergo transvaginal duplex sonography (TVUS) to identify refluxing pelvic veins. Those with positive scans undergo embolisation before surgical treatment of their lower limb varicose veins. A total of 218 women (mean age of 46.3 years) were treated. Parity was documented in the first 60 patients, of whom 47 (78.3%) were multiparous, 11 (18.3%) had had one previous pregnancy, and 2 (3.3%) were nulliparous. The left ovarian vein was embolised in 78%, the right internal iliac in 64.7%, the left internal iliac in 56.4%, and the right ovarian vein in 42.2% of patients. At follow-up TVUS, mild reflux only was seen in 16, marked persistent reflux in 6, and new reflux in 3 patients. These 9 women underwent successful repeat embolisation. Two patients experienced pulmonary embolisation of the coils, of whom 1 was asymptomatic and 1 was successfully retrieved; 1 patient had a misplaced coil protruding into the common femoral vein; and 1 patient had perineal thrombophlebitis. The results of our study showed that pelvic venous embolisation by way of a transjugular approach is a safe and effective technique in the treatment of pelvic vein reflux.

  18. Mesh Inguinal Hernia Repair and Appendectomy in the Treatment of Amyand’s Hernia with Non-Inflamed Appendices

    Full Text Available Amyand’s hernia is defined as protrusion of the vermiform appendix in an inguinal hernia sac. It is a rare entity with variable clinical presentation from normal vermiform appendix to abscess formation due to perforation of acute appendicitis. Although surgical treatment includes appendectomy and hernia repair, appendectomy in the absence of an inflamed appendix and use of a mesh in cases of appendectomy remain to be controversial. The aim of this study was to review the experience of mesh inguinal hernia repair plus appendectomy performed for Amyand’s hernia with noninflamed appendices. There were five male patients with a mean age of 42.4 ± 16.1 years in this retrospective study in which Amyand’s hernia was treated with mesh inguinal hernia repair plus appendectomy for noninflamed appendices. Patients with acute appendicitis and perforated vermiform appendix were excluded. There were four right sided and one bilateral inguinal hernia. Postoperative courses were uneventful. During the follow-up period (14.0 ± 7.7 months, there was no inguinal hernia recurrence. Mesh inguinal hernia repair with appendectomy can be performed for Amyand’s hernia in the absence of acute appendicitis. However, presence of fibrous connections between the vermiform appendix and the surrounding hernia sac may be regarded as a parameter to perform appendectomy.

    Chronic occlusions of the inferior vena cava (IVC) and iliofemoral veins are long-term sequelae of deep venous thrombosis (DVT) that can lead to postthrombotic syndrome (PTS). Patients may present with a wide spectrum of signs and symptoms, ranging from mild discomfort and swelling to severe venous hypertension and ulcerations. We report a 68-year-old man who had a history of left lower extremity DVT after a laminectomy and who developed PTS with nonhealing ulcers. The patient underwent a cross-pubic femorofemoral venous bypass that failed to improve his clinical status. After unsuccessful endovascular attempts for recanalization of the iliofemoral segment, a profunda femoris to IVC bypass was performed. The symptoms recurred 2 years later. Venography revealed restenosis at the caval anastomosis that did not resolve by endovascular means. A surgical revision was performed, and given the quality of the IVC, a jump bypass was created to the left renal vein. The swelling improved and the ulcers healed completely. Twenty-eight months after the complex reconstructions, he remains ulcer-free with mild edema controlled with stockings. Venous reconstructions remain a viable option for patients with symptomatic and recalcitrant nonmalignant obstruction of the large veins. Copyright © 2013 Annals of Vascular Surgery Inc.

    To describe our novel technique for performing a combined partial penectomy and bilateral robotic inguinal lymphadenectomy using intraoperative near-infrared (NIR) fluorescence guidance with indocyanine green (ICG) and the DaVinci Firefly camera system. A 58-year-old man presented status post recent excisional biopsy of a 2-cm lesion on the left coronal aspect of the glans penis. Pathology revealed "invasive squamous cell carcinoma of the penis with multifocal positive margins." His examination was suspicious for cT2 primary and his inguinal nodes were cN0. He was counseled to undergo partial penectomy with possible combined vs staged bilateral robotic inguinal lymphadenectomy. Preoperative computed tomography scan was negative for pathologic lymphadenopathy. Before incision, 5 mL of ICG was injected subcutaneously beneath the tumor. Bilateral thigh pockets were then developed simultaneously and a right, then left robotic modified inguinal lymphadenectomy was performed using NIR fluorescence guidance via the DaVinci Firefly camera. A partial penectomy was then performed in the standard fashion. The combined procedure was performed successfully without complication. Total operative time was 379 minutes and total robotic console time was 95 minutes for the right and 58 minutes to the left. Estimated blood loss on the right and left were 15 and 25 mL, respectively. A total of 24 lymph nodes were retrieved. This video demonstrates a safe and feasible approach for combined partial penectomy and bilateral inguinal lymphadenectomy with NIR guidance using ICG and the DaVinci Firefly camera system. The combined robotic approach has minimal morbidity and avoids the need for a staged procedure. Furthermore, use of NIR guidance with ICG during robotic inguinal lymphadenectomy is feasible and may help identify sentinel lymph nodes and improve the quality of dissection. Further studies are needed to confirm the utility of NIR guidance for robotic sentinel lymph node

  1. Resident postgraduate year does not influence rate of complications following inguinal herniorrhaphy.

    Previous data indicate that patients who undergo surgery with a postgraduate year 3 (PGY-3) resident as the junior surgeon have a lower rate of recurrence compared with PGY-1 and PGY-2 after an open inguinal herniorrhaphy. Lower PGY level was also associated with increased operative time. We hypothesize that when controlling for surgeon, technique, and hernia type, the outcomes for inguinal herniorrhaphy are the same independent of PGY level. A retrospective review of all open unilateral inguinal hernia repairs done by residents who assisted the same senior surgeon at the Veterans Affairs North Texas Health Care System was performed. Seven hundred fifty-two open unilateral inguinal hernia were identified: mean patient age = 60.6 ± 12.7 y; mean body mass index = 27.0 ± 10.8 kg/m 2 ; American Society of Anesthesia III-IV = 51%; and Nyhus type 2 = 44.7%, 3a = 41.6%, and 3b = 13.7%. Residents involved were PGY-1 (17.2%), PGY-2/3 (71.1%), and PGY-4/5 (11.7%). Postoperative complications for intern, junior (PGY-2 and PGY-3), and senior residents (PGY-4 and PGY-5) were 4%, 9%, and 6%, respectively (P = 0.14). Compared to interns, junior residents finished the operation 3.9 min faster (95% confidence interval = -7.5, -0.3). There was no time difference between interns and senior residents completing the operations after controlling for hernia type. Logistic regression did not identify PGY level as an independent predictor of complications or recurrence. There was a slight decrease in operative time when the repair was done with junior-level residents. PGY level did not influence outcomes for open, unilateral inguinal herniorrhaphy when controlled for hernia type and technique. Published by Elsevier Inc.

    Recent technical advances and a trend toward laparoscopic single incision surgery have led us to explore the feasibility of laparoendoscopic single-site (LESS) hernia repair. We present our technique and initial experience with LESS extraperitoneal inguinal hernia repair in 10 consecutive men with unilateral inguinal hernias. Age range was 43.7 (28-64) years. Mean body mass index was 28 (range 24-30). Six were left inguinal hernias. There were six indirect and four direct hernias. Three patients had undergone previous open appendectomy. Incarcerated or bilateral hernias were excluded from our initial series. All cases were performed by three surgeons who were experienced in conventional totally extraperitoneal laparoscopic hernia repair as well as experienced in LESS. A literature review of current single-port inguinal hernia repair data is also presented. The mean operative time was 53 minutes (range 45-65  min). The average length of skin incision was 2.8  cm (range 2.3-3.2  cm). No drain was necessary in any of the patients, while no recordable bleeding was observed. There were no intraoperative or immediate postoperative complications. Hospitalization period was 2 days for all patients. After a limited follow-up of 1 month, there have been no recurrences and no complaints of testicular pain. The results of the current series compare favorably with those found in a literature review. LESS extraperitoneal inguinal hernia repair is both feasible and safe, although more technically demanding than its conventional laparoscopic counterpart. Although the cosmetic result with the former approach may prove superior, there are standing questions regarding the complications and long-term outcome. Randomized and if possible blinded trials that compare conventional and single-incision laparoscopic hernia repair may help to distinguish the most advantageous technique.

    To assess the necessity to operate on non-incarcerated inguinal hernia in children within 7 days of diagnosis. Retrospective. Data on 360 children, 0-10 years old (104 girls and 256 boys) who were operated on for inguinal hernia between 1 January 1993-31 December 2001 at the St. Elisabeth Hospital in Tilburg, the Netherlands, were collected from the medical records. These data included sex, age, interval between diagnosis and repair, recurrence, incarceration, length of hospitalisation and complications. In the group of 113 children 0-1 years old, 137 inguinal hernias were repaired, ofwhich 16 were incarcerated on presentation. The interval between diagnosis and repair was known in 93 of 121 cases: 37 hernias were repaired within 7 days and 56 at a later stage. In the latter group, there was one case of secondary incarceration (1.8%; 95% CI: 0-5.4). The number needed to treat was 56. In the group of 247 children 1-10 years old, 269 inguinal hernias were repaired, of which 8 were primarily incarcerated. The interval between diagnosis and repair was known in 208 of 261 cases: 34 hernias were repaired within 7 days and 174 at a later stage. In the latter group, 3 hernias incarcerated secondarily (1.7%; 95% CI: 0-3.7). The number needed to treat was 58. In the group of non-incarcerated hernias 1 complication occurred, in the group of incarcerated hernias none. The mean length of hospitalisation of children with non-incarcerated hernia was 0.85 days, and of children with incarcerated hernia 2.4 days. In children with a non-incarcerated inguinal hernia who are waiting for an operation, the risk of secondary incarceration and complications is 2% which we do not think is enough reason to carry out an elective hernia-repair procedure within 7 days.

    The purpose of this paper was to evaluate the safety and technical success of TrapEase inferior vena cava filter placement via the subclavian vein. As of yet, no reports in the literature have specifically investigated the use of the subclavian vein as a route for deploying TrapEase vena cava filters. Retrospective chart review was conducted of 135 patients with attempted TrapEase inferior vena cava filter placement over a 2-year period. In a majority of cases, the choice of subclavian vein approach was based primarily on surgeon preference. Other circumstances for subclavian vein deployment included cervical immobilization secondary to trauma, desire for concomitant placement of a subclavian long-term central venous access catheter, and patient body habitus limiting exposure to the internal jugular vein. One hundred and thirty-five filters were placed over this 2-year period. The internal jugular vein approach was used in 56 patients, the femoral vein approach in 39 patients, and the subclavian vein approach in 40 patients. Thirty-nine of the 40 TrapEase filter placements using the subclavian vein were successful. Twenty-six were deployed through the right subclavian vein and 14 through the left subclavian vein. The single failed subclavian deployment was due to the inability to pass the guidewire adequately into the inferior vena cava after successful cannulation of the right subclavian vein. The average deployment time for subclavian vein placement was 26 minutes when TrapEase filter placement was the only procedure performed. No insertional complications were encountered, specifically no pneumothoraces confirmed by chest radiography or fluoroscopy. The subclavian vein provides an alternative site of access for the TrapEase inferior vena cava filter. This route is comparable to other alternative methods evaluated both in average deployment time and complication occurrence. Furthermore, the subclavian vein route is valuable in patients with limited central access

    Inguinal hernia repair is one of the most common operation in surgical practice. Despite its common occurrence, hernia often poses a surgical dilemma even for a skilled surgeon. The unexpected hernial content constitutes one of these cases. Although the often-reported, unusual contents of a hernia sac include ovary, fallopian tube, vermiform appendix, Meckel diverticulum, and urinary bladder, the herniation of a large ovarian cyst into the inguinal canal has been hardly reported. Majority of the ovarian cysts are asymptomatic or present with vague lower abdominal pain, whereas the presentation of a large ovarian cyst as an inguinolabial swelling as in our patient is extremely rare. We present here one of the few reported cases of a laparoscopic excision of a large ovarian cyst herniating into the inguinal canal and discuss the pathogenesis of an ovarian cyst as hernial content, the advantages and concerns of a laparoscopic approach in resecting large ovarian cysts, and simultaneous management of the inguinal hernia.

    Inguinal disruption, a common condition in athletes, is a diagnostic and therapeutic challenge. The aim of this study was to evaluate the effect of endoscopic totally extraperitoneal (TEP) repair in athletes with inguinal disruption, selected through a multidisciplinary, systematic work-up. An observational, prospective cohort study was conducted in 32 athletes with inguinal disruption. Athletes were assessed by a sports medicine physician, radiologist and hernia surgeon and underwent subsequent endoscopic TEP repair with placement of polypropylene mesh. The primary outcome was pain reduction during exercise on the numeric rating scale (NRS) 3 months postoperatively. Secondary outcomes were sports resumption, physical functioning and long-term pain intensity. Patients were assessed preoperatively, 3 months postoperatively and after a median follow-up of 19 months. Follow-up was completed in 30 patients (94%). The median pain score decreased from 8 [interquartile range (IQR) 7-8] preoperatively to 2 (IQR 0-5) 3 months postoperatively (p disruption, selected through a multidisciplinary, systematic work-up, benefit from TEP repair.

    Cellular angiofibroma is a rare benign mesenchymal tumor that occurs in the inguinal and vulvovaginal region. We report a case of the tumor occurring in the right inguinal region of a 64 old male and a review of the current literature. A 64 year old male veteran was referred to our general surgery service with an incidentally discovered right inguinal mass on a computerized tomography scan. The scan was performed to follow a history of prostate cancer that had been treated with brachytherapy. Magnetic resonance imaging of the lesion helped confirm that the mass did not represent a hernia or an undescended testicle. Surgical resection revealed encapsulated, yellowish, pink tissue measuring 6.5 x 5 x 3.5 cm. Microscopically, the sections showed densely fibrous to loose and focally fibromyxoid background of oval to spindle-shaped cells with a few scattered plasma cells and mast cells. Based upon the clinical, histologic, and immunohistochemical findings, the lesion was classified as a cellular angiofibroma. Cellular angiofibroma of the inguinal region is a rare benign encapsulated tumor.It should be considered in the differential diagnosis of a male with an inguinal mass proven not to be a hernia or undescended testicle.

    Acute renal failure due to ureter compression after a mesh-plug inguinal repair in a kidney transplant recipient has not been previously reported to our knowledge. A 62-year-old man, who successfully underwent kidney transplantation from a deceased donor 6 years earlier, was admitted for elective repair of a direct inguinal hernia. The patient underwent an open mesh-plug repair of the inguinal hernia with placement of a plug in the preperitoneal space. We did not observe the transplanted ureter and bladder during dissection of the inguinal canal. Immediately after surgery, the patient became anuric, and a graft sonography demonstrated massive hydronephrosis. The serum creatinine level increased rapidly, and the patient underwent an emergency reoperation 8 hours later. During surgery, we did not identify the ureter but, immediately after plug removal, urine output increased progressively. We completed the hernia repair using the standard technique, without plug interposition, and the postoperative course was uneventful with complete resolution of graft dysfunction 3 days later. Furthermore, we reviewed the clinical features of complications related to inguinal hernia surgery. An increased risk of urological complications was reported recently in patients with a previous prosthetic hernia repair undergoing kidney transplantation, mainly due to the mesh adhesion to surrounding structures, making the extraperitoneal dissection during the transplant surgery very challenging. Moreover, older male kidney transplant recipients undergoing an inguinal hernia repair may be at higher risk of graft dysfunction due to inguinal herniation of a transplanted ureter. Mesh-plug inguinal hernia repair is a safe surgical technique, but this unique case suggests that kidney transplant recipients with inguinal hernia may be at higher risk of serious urological complications. Surgeons must be aware of the graft and ureter position before proceeding with hernia repair. A prompt diagnosis

    Inguinal hernia repair is a common general surgery procedure with low morbidity. However, postoperative urinary retention (PUR) occurs in up to 22% of patients, resulting in further extraneous treatments.This single institution series investigates whether patient comorbidities, surgical approaches, and anesthesia methods are associated with developing PUR after inguinal hernia repairs. This is a single institution retrospective review of inguinal hernia from 2012 to 2015. PUR was defined as patients without a postoperative urinary catheter who subsequently required bladder decompression due to an inability to void. Univariate and multivariate logistic regressions were performed to quantify the associations between patient, surgical, and anesthetic factors with PUR. Stratification analysis was conducted at age of 50 years. 445 patients were included (42.9% laparoscopic and 57.1% open). Overall rate of PUR was 11.2% (12% laparoscopic, 10.6% open, and p = 0.64). In univariate analysis, PUR was significantly associated with patient age >50 and history of benign prostatic hyperplasia (BPH). Risk stratification for age >50 revealed in this cohort a 2.49 times increased PUR risk with lack of intraoperative bladder decompression (p = 0.013). At our institution, we found that patient age, history of BPH, and bilateral repair were associated with PUR after inguinal hernia repair. No association was found with PUR and laparoscopic vs open approach. Older males may be at higher risk without intraoperative bladder decompression, and therefore, catheter placement should be considered in this population, regardless of surgical approach.

This phone system requires new wiring system with the addition of new buildings in Nuclear Malaysia. The system also requires new parts to ensure smooth communication system in future. (author)

  12. Infra-red data of extended sources as a measure of the star formation rate

    1985-01-01

    Molecular cloud complexes are gravitationally bound systems which contain molecular clouds, HII regions and possibly OB associations after they evaporated their parent cloud. A large fraction of the energy (50%) radiated by the O and B stars is converted into infra-red. Less massive stars still embedded in molecular clouds or still in their vicinity will also see most of their radiation absorbed by dust and reemitted in the infra-red. The two quantities the author deduces directly from the data are: the ratio of the far-infra-red luminosity due to recently formed stars to the mass of gas, as a measure of the star formation rate; and the infra-red excess (IRE): the ratio of the far-infra-red luminosity to the luminosity of HII regions in the Lyman α line, which gives information on the initial mass function. Finally he discusses the possible links between star formation and some of the relevant physical conditions in the molecular clouds: amount and temperature distribution of dust. (Auth.)

    Full Text Available Paratesticular/scrotal and inguinal canal mass lesions in elderly patients may pose a diagnostic challenge to both the surgeon as well as the pathologist. In most cases, these represent hernial sacs with their contents, and true neoplasms like lipomas, rhabdomyosarcomas, and fibrous pseudotumors are infrequent. Malignant mesotheliomas arising from the tunica layers are rare cause of inguinal and paratesticular tumors. Herein, we report a case of an elderly patient who presented with an inguinal hernia which pathologically had features of deciduoid malignant mesothelioma.

  20. Minimal access surgery of pediatric inguinal hernias: a review.

    2008-08-01

    Inguinal hernia is a common problem among children, and herniotomy has been its standard of care. Laparoscopy, which gained a toehold initially in the management of pediatric inguinal hernia (PIH), has managed to steer world opinion against routine contralateral groin exploration by precise detection of contralateral patencies. Besides detection, its ability to repair simultaneously all forms of inguinal hernias (indirect, direct, combined, recurrent, and incarcerated) together with contralateral patencies has cemented its role as a viable alternative to conventional repair. Numerous minimally invasive techniques for addressing PIH have mushroomed in the past two decades. These techniques vary considerably in their approaches to the internal ring (intraperitoneal, extraperitoneal), use of ports (three, two, one), endoscopic instruments (two, one, or none), sutures (absorbable, nonabsorbable), and techniques of knotting (intracorporeal, extracorporeal). In addition to the surgeons' experience and the merits/limitations of individual techniques, it is the nature of the defect that should govern the choice of technique. The emerging techniques show a trend toward increasing use of extracorporeal knotting and diminishing use of working ports and endoscopic instruments. These favor wider adoption of minimal access surgery in addressing PIH by surgeons, irrespective of their laparoscopic skills and experience. Growing experience, wider adoption, decreasing complications, and increasing advantages favor emergence of minimal access surgery as the gold standard for the treatment of PIH in the future. This article comprehensively reviews the laparoscopic techniques of addressing PIH.

    A potentially less-invasive technique, transluminal surgery, may reduce or eliminate pain and decrease time to full return of activities after abdominal operations. Inguinal hernia repair is perfectly suited to the transgastric endoscopic approach and has not been previously reported. Our purpose was to evaluate the feasibility of transgastric bilateral inguinal herniorrhaphy (BIH). Feasibility study with a nonsurvival canine model. Under general anesthesia, male mongrel dogs weighing 20 to 30 kg had a dual-channel endoscope introduced into the peritoneal cavity over a percutaneously placed guidewire. An overtube with an insufflation channel was used. Peritoneoscopy was performed, and bilateral deep and superficial inguinal rings were identified. The endoscope was removed, premounted with a 4 x 6 cm acellular human dermal implant and then readvanced intraperitoneally through the overtube. The implant was then deployed across the entire myopectineal orifice and draped over the cord structures. Bioglue was then applied endoscopically, and the implant was attached to the peritoneum. After completion of bilateral repairs, the animals were killed and necropsy performed. Five dogs underwent pure natural orifice transluminal endoscopic surgery (NOTES) intraperitoneal onlay mesh (IPOM) BIH. Accurate placement and adequate myopectineal coverage was accomplished in all subjects. At necropsy no injuries to the major structures were noted but Bioglue misapplication with contamination of unintended sites did occur. Our study involved only a small number of subjects in nonsurvival experiments, and no gastric closure was used. Many of the characteristics of inguinal hernia repair are especially well suited to the transgastric approach. The repair is in line with the transgastric endoscope vector, bilateral defects are adjacent, and the IPOM technique does not require significant manipulation or novel instrumentation.

    There are few studies looking for collagen matrix defects in patients with inguinal bernia. To study the skin connective tissue in patients with and without inguinal bernia. Skin from the surgical wound was obtained from 23 patients with and 23 patients without inguinal bernia. The samples were processed for conventional light microscopy. Collagen fibers were stained with Van Giesson and elastic fibers with Weigert stain. Patients without hernia had compact collagen tracts homogeneously distributed towards the deep dermis. In contrast, patients with hernia had zones in the dermis with thinner and disaggregated collagen tracts. Connective tissue had a lax aspect in these patients. Collagen fiber density was 52% lower in patients with hernia, compared to subjects without hernia. No differences in elastic fiber density or distribution was observed between groups. Patients with inguinal bernia have alterations in skin collagen fiber quality and density.

  5. [Hidradenocarcinoma of the heel associated with inguinal metastases].

    Labbardi, W; Hali, F; Marnissi, F; Cribier, B; Chiheb, S

    Hidradenocarcinoma is a rare malignant tumour involving the sweat glands. It classically arises de novo, only rarely resulting from pre-existing hidradenoma. The literature contains few reports of lymph node metastasis in this tumour. We report a case of a patient with hidradenocarcinoma of the heel associated with inguinal node metastases. We report the case of a 64-year-old patient with a history of chronic smoking, who in the last two years developed a painless nodule in his right heel, with no prior injury, and which gradually increased in size to become an ulcerated tumour. Physical examination revealed a rounded tumour mass, ulcerated in the centre, and associated with multiple inguinal adenopathies. Histological and immunohistochemical examination was suggestive of hidradenocarcinoma. The patient had undergone extensive local excision with inguinal lymphadenectomy. Histological examination showed infiltration of lymph nodes by the tumour with capsular rupture. Radiotherapy was subsequently given. The outcome was good without recurrence after 34 months of follow-up. Hidradenocarcinoma is a rare malignant tumour. Diagnosis is based on histological and immunohistochemical examination. However, hidradenocarcinoma may on occasion be difficult to differentiate from hidradenoma, a benign tumour, hence the interest of complete surgical resection with safety margins even in the absence of cytological malignancy. Local recurrences are common. The occurrence of lymph node metastasis during hidradenocarcinoma has been described only rarely in the literature. Such metastases usually occur after tumour resection. The specific features of our case are the rarity of lymph node metastases in hidradenocarcinoma coupled with the fact that these metastases were discovered upon diagnosis of the primary tumour.

    Aim: To determine the efficacy of percutaneous transcatheter embolization in the management of patients with spermatic varicocoeles persisting or recurring after surgery. Materials and methods: Over a period of 10 years, 28 patients (age range 13–55 years) were referred for percutaneous transcatheter embolization of postsurgical, recurrent varicocoeles. Medical documents were retrospectively reviewed to evaluate past surgical history, subjective symptoms, and results of scrotal examination, ultrasound, and semen parameters. Pre-embolization venograms were analysed to assess the anatomy of the testicular vein. The technical and clinical outcomes of embolization were then determined. Results: The 28 patients included in the study had undergone laparoscopic varicocoelectomy (39.3%), high retroperitoneal ligation (25%), or inguinal ligation (25%). Subjective symptoms were scrotal pain (60.7%) and a palpable scrotal mass (50%) exclusively on the left side. Venograms revealed abnormalities of the left testicular vein in all cases. Embolization was technically successful in all but two cases, thus yielding an occlusion rate of 93%; a single case of suspected thrombophlebitis was the only complication. After excluding two, technically unsuccessful cases and one patient who was lost to follow-up, 25 patients underwent scrotal examination after embolization, which revealed complete resolution in 20 cases (80%), partial improvement in four cases (16%), and no improvement in a single case (4%). Among the follow-up group of patients, of the 12 who initially presented with scrotal pain, six (50%) were symptom-free and four (33.3%) had partial improvement. Conclusion: Percutaneous transcatheter embolization of the testicular vein is technically feasible and effective for managing postsurgical recurrent varicocoeles.

    Full Text Available Purpose. We report a novel technique which aided recanalization of an occluded portal vein for transjugular intrahepatic portosystemic shunt (TIPS creation in a patient with symptomatic portal vein thrombosis with cavernous transformation. Some have previously considered cavernous transformation a contraindication to TIPS. Case Presentation. 62-year-old man with chronic pancreatitis, portal vein thrombosis, portal hypertension and recurrent variceal bleeding presents with melena and hematemesis. The patient was severely anemic, hemodynamically unstable, and required emergent portal decompression. Attempts to recanalize the main portal vein using traditional transjugular access were unsuccessful. After percutaneous transhepatic right portal vein access and navigation of a wire through the occluded main portal vein, an angioplasty balloon was inflated at the desired site of shunt takeoff. The balloon was targeted and punctured from the transjugular approach, and a wire was passed into the portal system. TIPS placement then proceeded routinely. Conclusion. Although occlusion of the portal vein increases difficulty of performing TIPS, it should not be considered an absolute contraindication. We have described a method for recanalizing an occluded portal vein using a combined transhepatic and transjugular approach for TIPS. This approach may be useful to relieve portal hypertension in patients who fail endoscopic and/or surgical therapies.

    Full Text Available Surgical treatment of female stress urinary incontinence (SUI has become very pop- ular after respectable success with minimal invasive surgeries. This is the first report of long term vaginocutaneous fistula (VCF plus inguinal abcess after tension-free vaginal tape (TVT. A 67 year-old woman with vaginal discharge lasting more than 3 years complained with a painful swelling in the left inguinal area for the last three months. She had a medical history of TVT sling procedure for SUI six years ago. She had no history of pelvic surgery, cancer treatment or pelvic irradiation before or after TVT sling. No urethrovaginal or vesicovaginal fistula was found in physical examination and cystocopy. MRI showed a vaginocutenaous fistula and inguinal abcess. This case highlights the need for a high index of suspicion for VCF after TVT.

    Full Text Available Introduction Immunosuppressive effects of general anesthesia and surgery could have unexpected consequences in a child with recent infection. The incidence of myocarditis in childhood is unknown. Case outline During general anesthesia for inguinal hernia repair, a seven-year-old boy suddenly developed heart failure. Clinical presentation included hypotension, pulmonary edema, drop in hemoglobin oxygen saturation, ST segment elevation and premature ventricular contractions. Homodynamic stability and adequate oxygenation were achieved with dopamine and furosemide. Preoperative history, physical examination and complete blood count were unremarkable. Moderate cardiomegaly and pulmonary edema were present on chest radiography. Diminished left ventricular contractility found on echocardiography increased troponin I and CK-MB levels suggested myocardial injury. Increased C-reactive protein with lymphocytosis suggested inflammation as its cause. Parents failed to report rubella 10 days before the operation. A clinical diagnosis of myocarditis as a complication of rubella was based on increased titer of IgM to rubella. With intravenous immunoglobulin, corticosteroids and symptomatic treatment for heart failure, his condition improved and ejection fraction reached 68 % one month after operation. Conclusion In future, we need protocols with instructions for pediatric patients undergoing elective surgery and anesthesia after viral infections.

    Muramatsu, N.; Hiraoka, K.

    2006-01-01

    A method was developed to evaluate water contents of fruit trees using infra-red photography. The irrigation of potted satsuma mandarin trees and grapevines was suppressed to induce water stress. During the drought treatment the leaf edges of basal parts of the shoots of grapevines became necrotic and the area of necrosis extended as the duration of stress increased. Necrosis was clearly distinguished from the viable areas on infra-red images. In satsuma mandarin, an abscission layer formed at the basal part of the petiole, then the leaves fell. Thus, detailed analysis was indispensable for detecting of the leaf water content. After obtaining infra-red images of satsuma mandarin leaves with or without water stress, a background treatment (subtraction of the background image) was performed on the images, then the average brightness of the leaf was determined using image analyzing software (Image Pro-plus). Coefficient correlation between the water status index using the infra-red camera and water content determined from dry weight and fresh weight of leaves was significant (r = 0.917 for adaxial surface data and r = 0.880 for abaxial surface data). These data indicate that infra-red photography is useful for detecting the degree of plant water stress

    The purpose of this study was to describe the prevalence and distribution of staphylococcal species on the teat and inguinal skin of dairy heifers across the various stages of the heifer life cycle. The cross-sectional study included 106 Holstein heifers with an age range of 0 d to 27 mo that were selected from 11 different groups, based on housing type and age, on a single dairy operation. A composite swabbing sample including all 4 teats and a second composite sample including both inguinal regions of each heifer were collected using gas-sterilized electrostatic dusters (Swiffers; Procter and Gamble, Cincinnati, OH). Swabbing samples were mixed with 10 mL of sterile saline, agitated, and cultured on mannitol salt agar plates. At 24 h, plates were read and up to 10 staphylococcal colonies were saved for further analysis. Staphylococcal isolates were speciated using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry or PCR amplification and partial sequencing of rpoB or tuf. The prevalence of staphylococci was compared between the inguinal and teat regions using the chi-squared or Fisher's exact test, as applicable. Logistic regression models were used to investigate the relationship between a heifer's age (treated as a quantitative continuous variable) and the probability of isolating a given staphylococcal species from a given body site (inguinal region or teats). Overall, the most common species identified were Staphylococcus haemolyticus followed by Staphylococcus chromogenes, Staphylococcus xylosus, Staphylococcus devriesei, and Staphylococcus sciuri. Staphylococcus aureus was more prevalent on the teat than in the inguinal region, whereas Staphylococcus arlettae was more prevalent in the inguinal region than on the teat. All other staphylococcal species were as likely to be found on the teat skin as the inguinal region skin. Isolation from the inguinal and teat skin was associated with age for Staphylococcus agnetis, S. chromogenes

    After the introduction of mesh in inguinal hernia repair, the focus to improve surgical technique has changed from recurrence to chronic postoperative inguinal pain. At present, the most common surgical techniques are the Lichtenstein hernioplasty and total extraperitoneal procedure. Both techniques have their own specific disadvantages, with regard to potential nerve damage and the necessity of general anesthesia, respectively. The goal of this study was to evaluate the results of a new technique in which the inguinal nerves are not at risk, and in which general anesthesia is not needed: trans rectus sheath extraperitoneal procedure (TREPP). Between 2006 and 2010, a total of 1,000 patients were treated for inguinal hernia with TREPP. A questionnaire concerning pain, sensibility changes, patient satisfaction, and recurrence was sent to all patients. The questionnaire was completed by 932 patients. Almost 90% of patients had not experienced any pain since the surgical procedure; 8% of patients reported experiencing some pain, but less than preoperatively; and 2% of patients reported an increase in pain postoperatively. Recurrence occurred in 1 and 3% were unsure about this. Reduced sensibility of the scar, scrotum, and upper leg was reported by 12.4, 1.4, and 1.5%, respectively. Overall, 97.4% of patients were satisfied with the results of the surgical procedure. The time period in which TREPP was performed was not associated with any of the outcome measures. TREPP has proven to be a feasible new technique for inguinal hernia repair, with excellent results, justifying a randomized controlled trial in which TREPP should be compared with standard techniques.

    . Local anesthetic blocks, pharmacological management, and treatment with sensory stimulation methods were presented in seven studies. In spite of shortcomings, the data on surgical management demonstrate that neurectomy with or without mesh removal may provide long-lasting analgesic effects in most...... patients with severe PPP following inguinal hernia repair. The evidence base for other management methods is still fragile, although promising results appear in the neuromodulation studies. CONCLUSIONS: There is a need for improved study designs and, launching of large multicenter collaborative studies...

    The objective of this study was to evaluate outcome of total extraperitoneal laparoscopic inguinal hernia repair with Lichtenstein open repair in terms of postoperative pain. Study Design: Quasi experimental study. Place and Duration of Study: Surgical unit l Rawalpindi and Allied hospitals from January to June 2012. Patients and Methods: Sixty patients, with unilateral, primary, inguinal hernia were alternately allocated to undergo either total extraperitoneal (TEP) laparoscopic repair of inguinal hernia or Lichtenstein tension free, mesh repair of inguinal hernia. Pain scores at 12, 24, and 48 hours and at 7 days of follow up were noted using a visual analogue scale. Total number of intravenous injections of Diclofenac Sodium requested by the patient for pain relief was also noted. Results: At 12 hours after surgery, the mean pain scores in the TEP group were 3.1 ± 1.8 and in the Lichtenstein group they were 4.2 ± 2.1 (p 0.031). At 24 hours after surgery, the scores were 2.3 ± 1.5 and 3.1 ± 1.9 for the TEP and Lichtenstein groups, respectively (p = 0.026). At 48 hours after surgery, the mean pain scores in the TEP group were 1.5 ± 1.1 while in the Lichtenstein group they were 2.0 ± 1.6 (p = 0.041). At 7 days after surgery, the scores were 0.3 ± 0.5 in the TEP group and 0.4 ± 0.8 in the Lichtenstein group (0.137). The mean number of injection of Diclofenac Sodium required by the TEP and Lichtenstein groups was 3.1 ± 1.6 and 5.8 ± 2.2, respectively (p = 0.011). Conclusion: Less postoperative pain and requirement for analgesics were reported by patients who underwent total extraperitoneal laparoscopic repair of inguinal hernia as compared to those who underwent inguinal hernia repair by Lichtenstein tension free mesh hernioplasty.

    Full Text Available Portal vein thrombosis is an important cause of presinusoidal portal hypertension. Portal vein thrombosis commonly occurs in patient with cirrhosis, malignancy and prothrombotic states. Patients with acute portal vein thrombosis have immediate onset. Patients with chronic portal vein thrombosis have developed portal hypertension and cavernous portal transformation. Portal vein thrombosis is diagnosed with doppler ultrasound, computed tomography and magnetic resonance imaging. Therapy with low molecular weight heparin achieves recanalization in more than half of acute cases.

  7. Infra-slow oscillation (ISO of the pupil size of urethane-anaesthetised rats.

    Tomasz Blasiak

    Full Text Available Multiplicity of oscillatory phenomena in a range of infra-slow frequencies (<0.01 Hz has been described in mammalian brains at different levels of organisation. The significance and manifestation in physiology and/or behaviour of many brain infra-slow oscillations (ISO remain unknown. Examples of this phenomenon are two types of ISO observed in the brains of urethane-anaesthetised rats: infra-slow, rhythmic changes in the rate of action potential firing in a few nuclei of the subcortical visual system and a sleep-like cycle of activation/deactivation visible in the EEG signal. Because both of these rhythmic phenomena involve brain networks that can influence autonomic nervous system activity, we hypothesised that these two brain ISOs can be reflected by rhythmic changes of pupil size. Thus, in the present study, we used simultaneous pupillography and ECoG recording to verify the hypothesised existence of infra-slow oscillations in the pupil size of urethane-anaesthetised rats. The obtained results showed rhythmic changes in the size of the pupils and rhythmic eyeball movements in urethane-anaesthetised rats. The observed rhythms were characterised by two different dominant components in a range of infra-slow frequencies. First, the long component had a period of ≈ 29 minutes and was present in both the irises and the eyeball movements. Second, the short component had a period of ≈ 2 minutes and was observed only in the rhythmic constrictions and dilations of the pupils. Both ISOs were simultaneously present in both eyes, and they were synchronised between the left and right eye. The long ISO component was synchronised with the cyclic alternations of the brain state, as revealed by rhythmic changes in the pattern of the ECoG signal. Based on the obtained results, we propose a model of interference of ISO present in different brain systems involved in the control of pupil size.

    Since 6 years, the totally extraperitoneal laparoscopic hernia repair has become our procedure of choice to manage inguinal hernia in adult patients, especially for bilateral hernias and recurrences after classical anterior repair. Between March 1993 and March 1999, 976 patients underwent 1259 hernia repairs by an endoscopic total extraperitoneal approach. A large polypropylene prosthesis (15 x 15 cm) is placed and covers all potential defects. Follow-up on patients ranged from 6 to 79 months (mean, 39 months). Per- and postoperative morbidity and complications were acceptable (8.4%) and included conversion to open surgery (0.4%), bleedings (0.3%), urinary retention (4.2%), seromas (2.7%), neuralgias (0.2%), vague persistent groin discomfort (0.4%), orchitis (0.08%) and sigmoido-cutaneous fistula (0.08%). Recurrence rate so far is 0.1%. This retrospective study shows that the totally extraperitoneal repair for inguinal hernia should have a promising future because of low morbidity and low recurrence rate.

    Hernias are a common occurrence with correspondingly huge clinical and economic impacts on the healthcare system. The most common forms of hernia which need to be diagnosed and treated in routine urological work are inguinal and umbilical hernias. With the objective of reconstructing and stabilizing the inguinal canal there are the possibilities of open and minimally invasive surgery and both methods can be performed with suture or mesh repair. Indications for surgery of umbilical hernias are infrequent although this is possible with little effort under local anesthesia. This article presents an overview of the epidemiology, pathogenesis, clinical symptoms, diagnostics and therapy of inguinal, femoral and umbilical hernias.

    Twelve patients with left renal vein stenosis from tumor compression were studied with CT. All had distended collateral veins in the perirenal space which either formed a radiating or a cobweb pattern or appeared as marked longitudinal veins. Inferior phrenic vein branches were seen in seven patients and were considerably enlarged in two. Other major veins possibly taking part in collateral circulation could not be recognized due to obliteration of fat planes. The renal fascia was thickened in eleven patients, probably due to edema. A close study of the perirenal space with CT may give valuable information about collateral development.

    Treatment of venous ulcers is demanding for patients, as well as clinicians, and the investigation of underlying venous hypertension is the cornerstone of therapy. We propose that occult iliac vein stenosis should be ruled out by iliac vein interrogation (IVI) in patients with advanced venous stasis. We conducted a systematic retrospective analysis of a consecutive series of patients who presented with CEAP (clinical, etiological, anatomical, and pathophysiological) 6 venous disease. All patients had great saphenous vein ablation, compressive treatment, wound care (including Unna boot compression), and perforator closure using ablation therapy. Iliac vein stenosis was defined as ≥50% stenosis in cross-sectional surface area on intravascular ultrasound. Primary outcomes include time of venous ulcer healing and/or measurable change in the Venous Clinical Severity Score. Twenty-two patients with CEAP 6 venous disease met the inclusion criteria (active ulcers >1.5 cm in diameter). The average age and body mass index were 62.2 ± 9.2 years and 41.7 ± 16.7, respectively. The majority were female (72.7%) with common comorbidities, such as hyperlipidemia (54.5%), hypertension (36.4%), and diabetes mellitus (27.3%). Twenty-nine ulcers with an average diameter of 3.4 ± 1.9 cm and a depth of 2.2 ± 0.5 mm were treated. The majority of the ulcers occurred on the left limb (n = 17, 58.6%). Average perforator venous reflux was 3.6 ± 0.8 sec, while common femoral reflux was 1.8 ± 1.6. The majority (n = 19, 64.5%) of the perforator veins were located at the base of the ulcer, while the remainder (n = 10, 34.5%) were within 2 cm from the base. Of the 13 patients who underwent IVI, 8 patients (61.5%) had stenosis >50% that was corrected with iliac vein angioplasty and stenting (IVAS). There was a strong trend toward shorter healing time in the IVI group (7.9 ± 9.5 weeks) than for patients in the no iliac vein interrogation (NIVI) group (20.2 ± 15

    Full Text Available A variety of surprises may spring up when the sac is opened in an inguinal hernia. Omentum, bowel diverticulum, ovary, fallopian tube, urinary bladder, large bowel, Meckel’s diverticulum or foreign bodies being the varied contents of a hernia sac. The presence of vermiform appendix in the hernia sac in an inguinal hernia is a rare finding. This condition has been named as “Amyand’s Hernia” in the honour of an English surgeon, Claudius Amyand. A diagnosis preoperatively is difficult and is most often made intraoperatively. We report here a 52-year-old patient who presented with acute intestinal obstruction due to an obstructed right sided inguinal hernia. A diagnosis of Amyand’s hernia was confirmed when on exploration appendix along with a part of ascending colon was found to be content of the sac along with a few loops of small bowel. The contents were reduced after checking the viability and Bassini’s repair was done. The patient had an uneventful postoperative period.

    Full Text Available Background Abnormalities of external genitalia in male children nurseries and inguinal hernia are the most common congenital disorders in children. We aimed to determine prevalence rate of inguinal hernia and other genital among children nurseries, in Shahrood-Iran. Materials and Methods In this descriptive cross-sectional study, we examined 920 children nurseries boys. Physical examination of children was performed in presence of a parent in a warm room in supine and upright position with and without Valsalva maneuver. A written consent was obtained from parents before examination. Past medical history and history of surgery on inguinal and genital area was taken. Examination was performed 2 interns who were trained about genital system examination.   Results A total of 920 children nurseries boys aged 3 to 6 years were examined which were detected in 88 children and prevalence rate of these abnormalities were 9.6%. The prevalence of abnormalities in the children under study were as follows: Inguinal hernia (5.1%, cryptorchidism (2.1%, Hydrocele (1.5%, hypospadias (0.4%, Varicocele (0.1%, micropenis (0.4%. Conclusion Regarding to relatively high prevalence rate of these abnormalities and low level of people knowledge, seem screening systems for diagnosis and appropriate treatment of these abnormalities to be necessary.

    Cosmic dust brings considerably high intensity of energy flux to the upper atmosphere of the earth. Most of this energy can be converted to infra-red radiation. It can be concluded that the infra-red background radiation in the sky of its wavelength of less than about 10μ may considerably originate in the cosmic dust which has entered the earth's atmosphere, or that the upper limit to the flux of cosmic dust is about 10 5 tons/earth year.

    Anatomic dye injection studies of the blood supply of colorectal hepatic metastases suggest that tumors are supplied predominantly by the hepatic artery. Using 13 N amino acids with dynamic gamma camera imaging in patients with colorectal hepatic metastases, it has been shown that hepatic artery infusion results in a significantly greater nutrient delivery to tumor compared with portal vein infusion. However, direct measurements of drug levels in tumor following hepatic artery and portal vein infusion in humans have not previously been reported. Patients with metastatic colorectal cancer confined to the liver received fluorodeoxyuridine (FUdR) through the hepatic artery or through the portal vein. All patients had previously failed systemic chemotherapy. Five patients with hepatic artery catheters were matched (by age, serum lactic dehydrogenase levels, percent hepatic replacement, and tumor size) with five patients with portal vein catheters. At operation, 3 H-FUdR (1 microCi/kg) and /sup 99m/Tc-macroaggregated albumin (MAA) (6 mCi) were injected into the hepatic artery or portal vein. Liver and tumor biopsies were obtained two and five minutes later. 3 H and /sup 99m/Tc were measured per gram tissue by scintillation and gamma counting. The mean liver levels following hepatic artery infusion (23.9 +/- 11.4 nmol/g) and portal vein infusion (18.4 +/- 14.5 nmol/g) did not differ. However, the mean tumor FUdR level following hepatic artery infusion was 12.4 +/- 12.2 nmol/g, compared with a mean tumor FUdR level following portal vein infusion of 0.8 +/- 0.7 nmol/g (P less than .01). This low level of tumor drug uptake after portal vein infusion of FUdR predicts minimal tumor response to treatment via this route. Thus, regional chemotherapy for established colorectal hepatic metastases should be administered through the hepatic artery

    Endoscopic surgical repair of inguinal hernia is currently conducted using 2 techniques: the totally extraperitoneal (TEP) and the transabdominal (TAPP) hernia repair. The TEP procedure is technically advantageous, because of the use of no mesh fixation and the elimination of the peritoneal flap, leading to less postoperative pain and faster recovery. The drawback is that TEP is not performed as frequently, because of its complexity and longer learning curve. In this study, we propose a hybrid technique that could potentially become the gold standard of minimally invasive inguinal hernia surgery. This will be achieved by combining established advantages of TEP and TAPP associated with the precision and cosmetics of minilaparoscopy (MINI). Between January and July 2011, 22 patients were admitted for endoscopic inguinal hernia repair. The combined technique was initiated with TAPP inspection and direct visualization of a minilaparoscopic trocar dissection of the preperitoneum space. A10-mm trocar was then placed inside the previously dissected preperitoneal space, using the same umbilical TAPP skin incision. Minilaparoscopic retroperitoneal dissection was completed by TEP, and the surgical procedure was finalized with intraperitoneal review and correction of the preperitoneal work. The minilaparoscopic TEP-TAPP combined approach for inguinal hernia is feasible, safe, and allows a simple endoscopic repair. This is achieved by combining features and advantages of both TAPP and TEP techniques using precise and sophisticated MINI instruments. Minilaparoscopic preperitoneal dissection allows a faster and easier creation of the preperitoneal space for the TEP component of the procedure.

  10. Dynamics of Nearshore Sand Bars and Infra-gravity Waves: The Optimal Theory Point of View

    Science.gov (United States)

    Bouchette, F.; Mohammadi, B.

    2016-12-01

    It is well known that the dynamics of near-shore sand bars are partly controlled by the features (location of nodes, amplitude, length, period) of the so-called infra-gravity waves. Reciprocally, changes in the location, size and shape of near-shore sand bars can control wave/wave interactions which in their turn alter the infra-gravity content of the near-shore wave energy spectrum. The coupling infra-gravity / near-shore bar is thus definitely two ways. Regarding numerical modelling, several approaches have already been considered to analyze such coupled dynamics. Most of them are based on the following strategy: 1) define an energy spectrum including infra-gravity, 2) tentatively compute the radiation stresses driven by this energy spectrum, 3) compute sediment transport and changes in the seabottom elevation including sand bars, 4) loop on the computation of infra-gravity taking into account the morphological changes. In this work, we consider an alternative approach named Nearshore Optimal Theory, which is a kind of breakdown point of view for the modeling of near-shore hydro-morphodynamics and wave/ wave/ seabottom interactions. Optimal theory applied to near-shore hydro-morphodynamics arose with the design of solid coastal defense structures by shape optimization methods, and is being now extended in order to model dynamics of any near-shore system combining waves and sand. The basics are the following: the near-shore system state is through a functional J representative of the energy of the system in some way. This J is computed from a model embedding the physics to be studied only (here hydrodynamics forced by simple infra-gravity). Then the paradigm is to say that the system will evolve so that the energy J tends to minimize. No really matter the complexity of wave propagation nor wave/bottom interactions. As soon as J embeds the physics to be explored, the method does not require a comprehensive modeling. Near-shore Optimal Theory has already given

    We report on various works carried four decades ago, so as to develop Heterodyne Interferometry in InfraRed (10 μm) at Calern Observatory (OCA, France), by building an experiment, whose the acronym "SOIRDETE" means "Synthese d'Ouverture en InfraRouge par Detection hETErodyne". Scientific and technical contexts by this time are recalled, as well as basic principles of heterodyne interferometry. The preliminary works and the SOIRDETE experiment are briefly described. Short comments are given in conclusion regarding the difficulties which have prevented the full success of the SOIRDETE experiment.

    Chances of avascular necrosis of acetabulum are rare as it enjoys a rich blood supply. But cases of post - traumatic avascular necrosis of acetabulum following fracture of posterior column have been well documented. Importance of identifying and suspecting the avascular necrosis of acetabulum is essential in cases of failed fixation of fracture acetabulum, previously operated using extensile approach to acetabulum; either extended anterior ilio - femoral or tri - radiate approach. Such patients usually present with repeated deep bone infection or with early failure of fixation with aseptic loosening and migration of its components. We present a similar case. 40 years female presented with inadequately managed transverse fracture of left acetabulum done by anterior extended ilio-inguinal approach. The fixation failed. She presented 6 months later with painful hip. Cemented total hip replacement was performed with reconstruction of acetabulum by posterior column plating. Six months postoperatively patient presented with dislodgement of cup, pelvic discontinuity and sinus in the thigh. Two stage revision surgery was planned. First implant, removal; debridement and antibiotic spacer surgery was performed. At second stage of revision total hip replacement, patient had Paprosky grade IIIb defect in acetabulum. Spacer was removed through the posterior approach. Anterior approach was taken for anterior plating. Intra-operatively external iliac pulsations were found to be absent so procedure was abandoned after expert opinion. Postoperatively digital subtraction angiography demonstrated a chronic block in the external iliac artery and corona mortis was the only patent vascular channel providing vascular to the left lower limb. Thus, peripheral limb was stealing blood supply from the acetabulum to maintain perfusion. Patient was ultimately left with pelvic discontinuity, excision arthroplasty and pseudoarthrosis of the left hip. Avascular necrosis of acetabulum is a rare

    The studies were carried out on heating horticultural substrate (moor peat - bark, 1:1 by volume) with a gas-fired infra-red radiator to destroy the pests and pathogens. Minimum distance between radiator and substrate surface was determined considering assumed time of heating. Dynamics of substrate heating was determined depending on its layer thickness and kind of surface under substrate layer; black rubber, ground steel sheet and aluminium foil were used as the surface. Considerable decreasing of infra-red radiation penetrability through the substrate layer above 7 mm thick was found as well as an significant effect of the radiation reflected from the surface under substrate layer on the intensity of its heating. It was also stated that heating horticultural substrates with the gas-fired infra-red radiator enables to rise the temperature of thin substrate layer up to 70 degree of C within relatively short time [pl

    To date, there are no prospective randomized studies that compare the outcome of endoscopic repair of primary versus recurrent inguinal hernias. It is therefore now attempted to answer that key question on the basis of registry data. In total, 20,624 patients were enrolled between September 1, 2009, and April 31, 2013. Of these patients, 18,142 (88.0%) had a primary and 2482 (12.0%) had a recurrent endoscopic repair. Only patients with male unilateral inguinal hernia and with a 1-year follow-up were included. The dependent variables were intra- and postoperative complications, reoperations, recurrence, and chronic pain rates. The results of unadjusted analyses were verified via multivariable analyses. Unadjusted analysis did not reveal any significant differences in the intraoperative complications (1.28 vs 1.33%; p = 0.849); however, there were significant differences in the postoperative complications (3.20 vs 4.03%; p = 0.036), the reoperation rate due to complications (0.84 vs 1.33%; p = 0.023), pain at rest (4.08 vs 6.16%; p primary versus recurrent male unilateral inguinal hernia showed significant differences to the disadvantage of the recurrent operation. Therefore, endoscopic repair of recurrent inguinal hernias calls for particular competence on the part of the hernia surgeon.

    62 year old Caucasian female with pancreatic head mass abutting the superior mesenteric vein (SMV) presented with fine needle aspiration biopsy confirmed diagnosis of ductal adenocarcinoma. CT scan showed near complete obstruction of portal vein and large SMV collateral development. After 3 months of neoadjuvant therapy, her portal vein flow improved significantly, SMV collateral circulation was diminished. Pancreaticoduodenectomy (PD) and superior mesenteric portal vein (SMPV) confluence resection were performed; A saphenous vein interposition graft thrombosed immediately. The splenic vein remnant was distended and adjacent to the stump of the portal vein. Harvesting an internal jugular vein graft required extra time and using a synthetic graft posed a risk of graft thrombosis or infection. As a result, we chose to perform a direct anastomosis of the portal and splenic vein in a desperate situation. The anastomosis decompressed the mesenteric venous system, so we then ligated the SMV. The patient had an uneventful postoperative course, except transient ascites. She redeveloped ascites more than one year later. At that time a PET scan showed bilateral lung and right femur metastatic disease. She expired 15 months after PD. The lessons we learned are (1) Before SMPV confluence resection, internal jugular vein graft should be ready for reconstruction. (2) Synthetic graft is an alternative for internal jugular vein graft. (3) Direct portal vein to SMV anastomosis can be achieved by mobilizing liver. (4) It is possible that venous collaterals secondary to SMV tumor obstruction may have allowed this patient's post-operative survival.

    2004-12-01

    Full Text Available Background. Myomas are the most frequent gynecological tumors. They first occur during puberty; however, they are most frequent among aged between 35 and 50. In this age group their incidence is 15–20%. They are rare after menopause. The majority of myomas arise in the uterus, but they may arise from other extrauterine sites such as the fallopian tubes, ovaries, round ligament, ligamentum latum, sacrouterine ligament, vagina and even the urethra. Most authors agree that there are numerous causes for the occurrence of myomas; however, they have not yet been clearly proven. They however agree that the myomas appear most frequently in the reproductive age, when the ovarian hormone levels are high and they diminish after menopause. They equally agree that the risk factors for the clinically significant myomas are nulliparity, obesity, a positive family history of myomas and African racial origin.Patients and methods. A 43-year-old patient was referred to our institution for operative treatment by her personal gynaecologist who clinically and sonografically verified a solid tumor situated to the right side of the uterus. The size of the tumor was that of a newborn’s head. The patient, however, had been observing a reponible inguinal hernia the size of a female fist for a period of four years. A solid tumor (22×6×7 cm arising from the right round ligament, was remowed during surgery. Half of its size was situated in the inguinal canal thus mimicking the clinical appearance of the inguinal hernia. After the tumor was removed the inner door of the inguinal canal closed by itself, no surgical repair was necessary. On histological examination the tumor was classified as a leiomyoma.Conclusions. Although the leiomyoma of the round ligament is the most frequent tumor of that region it is a rare gynecological tumor. The described case is especially interesting due to the unusual position of the tumor. It was situated partly intraabdominally and partly

    We had reported that the brain atrophy progressed significantly with advancing age using the two dimensional CT measurement by digitizer which was connected with personal computer. Using this method, we studied the age-related infra-tentrial brain atrophy in 67 normal subjects (14-90 years), and compared that with age-related supra-tentrial brain atrophy. There was a significant correlation between age and all indices [cranio-ventricular index (CVI), ventricular area index (VAI) and brain atrophy index (BAI)] in supratentrial brain. These indices did not correlated to the age in infra-tentrial brain (brainstem and cerebellum). Significant change of the brain atrophy occured above 60 years old was observed by BAI and VAI in supra-tentrial brain. There was a significant correlation between supra-tentrial brain atrophy index (BAI) and that of infratentrial brain. These results indicate that age-related brain atrophy might progress more slowly in brainstem and cerebellum than in cerebrum. (author)

    Inguinal hernia remains the most commonly encountered surgical problem. Various methods of repair have been described, and the most suitable one debated. Single port access (SPA) surgery is a rapidly evolving field, and has the advantage of affording 'scarless' surgery. Single incision laparoscopic surgery (SILS) for inguinal hernia repair is seen to be feasible in both total extraperitoneal (TEP) and transabdominal pre-peritoneal (TAPP) approaches. Data and peri-operative information on both of these however are limited. We aimed to review the clinical experience, feasibility and short term complications related to laparoscopic inguinal hernia repair via single port access. A literature search was performed using Google Scholar, Springerlink Library, Highwire Press, Surgical Endoscopy Journal, World Journal of Surgery and Medscape. The following search terms were used: laparoscopic hernia repair, TAPP, TEP, single incision laparoscopic surgery (SILS). Fourteen articles in English language related to SILS inguinal hernia repair were identified. Nine articles were related to TEP repair and the remaining 5 to TAPP. A total of 340 patients were reported within these studies: 294 patients having a TEP repair and 46 a TAPP. Only two cases of recurrence were reported. Various ports have been utilized, including the SILS port, Tri-Port and a custom- made port using conventional laparoscopic instruments. The duration of surgery was 40-100 minutes and the average length of hospital stay was one day. Early outcomes of this novel technique show it to be feasible, safe and with potentially better cosmetic outcome.

Conclusion: Creation of neo-inguinal canal medial to the medial umbilical ligament and just lateral to the bladder has the advantage of gaining more length on the vessels and vas to bring the testis to scrotum. The laparoscopic management of undescended testis in stage II by this innovative new route is simple, less complicated and well tolerated.

    62 year old Caucasian female with pancreatic head mass abutting the superior mesenteric vein (SMV) presented with fine needle aspiration biopsy confirmed diagnosis of ductal adenocarcinoma. CT scan showed near complete obstruction of portal vein and large SMV collateral development. After 3 months of neoadjuvant therapy, her portal vein flow improved significantly, SMV collateral circulation was diminished. Pancreaticoduodenectomy (PD) and superior mesenteric portal vein (SMPV) confluence resection were performed; A saphenous vein interposition graft thrombosed immediately. The splenic vein remnant was distended and adjacent to the stump of the portal vein. Harvesting an internal jugular vein graft required extra time and using a synthetic graft posed a risk of graft thrombosis or infection. As a result, we chose to perform a direct anastomosis of the portal and splenic vein in a desperate situation. The anastomosis decompressed the mesenteric venous system, so we then ligated the SMV. The patient had an uneventful postoperative course, except transient ascites. She redeveloped ascites more than one year later. At that time a PET scan showed bilateral lung and right femur metastatic disease. She expired 15 months after PD. Conclusion The lessons we learned are (1) Before SMPV confluence resection, internal jugular vein graft should be ready for reconstruction. (2) Synthetic graft is an alternative for internal jugular vein graft. (3) Direct portal vein to SMV anastomosis can be achieved by mobilizing liver. (4) It is possible that venous collaterals secondary to SMV tumor obstruction may have allowed this patient's post-operative survival. PMID:25568802

    Inguinal hernia repair is one of the most commonly performed operations in the pediatric population. While the majority of pediatric surgeons routinely use laparoscopy in their practices, a relatively small number prefer a laparoscopic inguinal hernia repair over the traditional open repair. This article provides an overview of the three port laparoscopic technique for inguinal hernia repair, as well as a review of the current evidence with respect to visualization and identification of hernias, recurrence rates, operative times, complication rates, postoperative pain, and cosmesis. The laparoscopic repair presents a viable alternative to open repair and offers a number of benefits over the traditional approach. These include superior visualization of the relevant anatomy, ability to assess and repair a contralateral hernia, lower rates of metachronous hernia, shorter operative times in bilateral hernia, and the potential for lower complication rates and improved cosmesis. This is accomplished without increasing recurrence rates or postoperative pain. Further research comparing the different approaches, including standardization of techniques and large randomized controlled trials, will be needed to definitively determine which is superior.

  19. Orchiectomy as a result of ischemic orchitis after laparoscopic inguinal hernia repair: case report of a rare complication.

    Science.gov (United States)

    Moore, John B; Hasenboehler, Erik A

    2007-11-07

    Ischemic orchitis is an established complication after open inguinal hernia repair, but ischemic orchitis resulting in orchiectomy after the laparoscopic approach has not been reported. The patient was a thirty-three year-old man who presented with bilateral direct inguinal hernias, right larger than left. He was a thin, muscular male with a narrow pelvis who underwent bilateral extraperitoneal mesh laparoscopic inguinal hernia repair. The case was complicated by pneumoperitoneum which limited the visibility of the pelvic anatomy; however, the mesh was successfully deployed bilaterally. Cautery was used to resect the direct sac on the right. The patient was discharged the same day and doing well with minimal pain and swelling until the fourth day after surgery. That night he presented with sudden-onset pain and swelling of his right testicle and denied both trauma to the area and any sexual activity. Ultrasound of the testicle revealed no blood flow to the testicle which required exploration and subsequent orchiectomy. Ischemic orchitis typically presents 2-3 days after inguinal hernia surgery and can progress to infarction. This ischemic injury is likely due to thrombosis of the venous plexus, rather than iatrogenic arterial injury or inappropriate closure of the inguinal canal. Ultrasound/duplex scanning of the postoperative acute scrotum can help differentiate ischemic orchitis from infarction. Unfortunately, testicular torsion cannot be ruled out and scrotal exploration may be necessary. Although ischemic orchitis, atrophy, and orhiectomy are uncommon complications, all patients should be warned of these potential complications and operative consent should include these risks irrespective of the type of hernia or the surgical approach.

    Adrenal vein sampling (AVS) is the gold standard test to determine unilateral causes of primary aldosteronism (PA). We have retrospectively characterized our experience with AVS including concordance of AVS results and imaging, and describe the approach for the PA patient in whom bilateral AVS is unsuccessful. We reviewed the medical records of 85 patients with PA and compared patients who were treated medically and surgically on pre-procedure presentation and post-treatment outcomes, and evaluated how technically unsuccessful AVS results were used in further patient management. Out of the 92 AVS performed in 85 patients, AVS was technically successful bilaterally in 58 (63%) of cases. Either unsuccessful AVS prompted a repeat AVS, or results from the contralateral side and from CT imaging were used to guide further therapy. Patients who were managed surgically with adrenalectomy had higher initial blood pressure and lower potassium levels compared with patients who were managed medically. Adrenalectomy results in significantly decreased blood pressure and normalization of potassium levels. AVS can identify surgically curable causes of PA, but can be technically challenging. When one adrenal vein fails to be cannulated, results from the contralateral vein can be useful in conjunction with imaging and clinical findings to suggest further management.

    Full Text Available Abstract Background Anterior open treatment of the inguinal hernia with a tension free mesh has reduced the incidence of recurrence and direct postoperative pain. The Lichtenstein procedure rules nowadays as reference technique for hernia treatment. Not recurrences but chronic pain is the main postoperative complication in inguinal hernia repair after Lichtenstein's technique. Preliminary experiences with a soft mesh placed in the preperitoneal space showed good results and less chronic pain. Methods The TULIP is a double-blind randomised controlled trial in which 300 patients will be randomly allocated to anterior inguinal hernia repair according to Lichtenstein or the transinguinal preperitoneal technique with soft mesh. All unilateral primary inguinal hernia patients eligible for operation who meet inclusion criteria will be invited to participate in this trial. The primary endpoint will be direct postoperative- and chronic pain. Secondary endpoints are operation time, postoperative complications, hospital stay, costs, return to daily activities (e.g. work and recurrence. Both groups will be evaluated. Success rate of hernia repair and complications will be measured as safeguard for quality. To demonstrate that inguinal hernia repair according to the transinguinal preperitoneal (TIPP technique reduces postoperative pain to Discussion The TULIP trial is aimed to show a reduction in postoperative chronic pain after anterior hernia repair according to the transinguinal preperitoneal (TIPP technique, compared to Lichtenstein. In our hypothesis the TIPP technique reduces chronic pain compared to Lichtenstein. Trial registration ISRCTN 93798494

    Chronic pain in the hip, groin or thigh can be caused by a wide spectrum of diseases posing extended diagnostic problems. We describe the case of a 10-years old child with chronic pain in the groin with gait restriction for more than six months without successful classification and treatment. The girl suffered from heavy pain in the groin after a sporting contest which forced her to walk with walking sticks and to avoid climbing stairs. Within six months she was examined by pediatric, orthopedic, pediatric surgery, pediatric orthopedic, radiology, pediatric rheumatology specialists. Working diagnoses were transient synovitis (coxitis fugax), arthritis, streptococcal arthritis, Morbus Perthes, rheumatic fever, rheumatoid arthritis. She was treated with antibiotics and ibuprofen in high dosage. Repeated laboratory tests and imaging studies (ultrasound, x-rays, magnetic resonance imaging) of the hip and pelvis did not support any of these diagnoses. Six months after beginning of the complaints the girl was presented by her mother to our institution. The physical examination showed a sharp localized pain in the groin, just in the region of the inguinal ligament with otherwise free hip movement. There was no visible inguinal hernia. The family history for hernia was positive. After infiltration of the ilioinguinal nerve the girl had a complete long-lasting disappearance of pain and gait disturbance. This led to the diagnosis of inguinal hernia with nerve entrapment. After hernia repair and neurolysis/neurectomy there was a continuous state of disappearance of pain and gait disturbances. To avoid such a diagnostic dilemma one should always discuss all possible causes. Non-visible inguinal hernia may be more common in females than previously thought. Nerve entrapment as a cause of groin pain has been well described. The relationship of the start of complaints with sporting activity, a positive family history for inguinal hernia, a lack of signs of inflammation and bone

    Purpose: Central venous cannulation via the common femoral vein is an important starting point for many interventions. The purpose of this study was to determine the optimum conditions for cannulation of the femoral vein and to compare these with the relative changes in the internal jugular vein. Methods: High-resolution 2D ultrasound was utilised to determine variability of the calibre of the femoral and internal jugular veins in 10 healthy subjects. Venous diameter was assessed during the Valsalva manoeuvre and in different degrees of the Trendelenburg position. Results: The Valsalva manoeuvre significantly increased the size of the femoral and internal jugular veins. There was a relatively greater increase in femoral vein diameter when compared with the internal jugular vein of 40 and 29%, respectively. Changes in body inclination (Trendelenburg position) did not significantly alter the luminal diameter of the femoral vein. However, it significantly increased internal jugular vein diameter. Conclusions: Femoral vein cannulation is augmented by the Valsalva manoeuvre but not significantly altered by the gravitational position of the subject.

The utilization of ultrasound has greatly augmented the success rate of this block and additionally avoiding complications. The aim of our study was to gauge the analgesic efficacy of ultrasound-guided TAP block in patients undergoing unilateral inguinal hernia repair. Materials and methods: Sixty patients scheduled for elective inguinal hernia repair were selected for the study. At the end of the surgical procedure, they were randomly divided into two groups. Ultrasound-guided TAP block was performed with 20 mL of ropivacaine 0.2% (group A or normal saline (group B. Visual analog scale (VAS scores were used to assess pain. Paracetamol was given if VAS >3 and tramadol was used when VAS >6. Patients were monitored for VAS scores and total analgesic consumption for the 24-hour period. Results: The TAP block with ropivacaine (group A reduced VAS scores at 4, 6, and 12 hours. There was no distinction in VAS scores at 0, 2, and 24 hours between the two groups. The duration of analgesia for TAP block with ropivacaine lasted for 390 minutes. Total analgesics consumption was also significantly reduced in group A than group B. No complication was reported to TAP block in both the groups. Conclusion: The ultrasound-guided TAP block provides good postoperative analgesia, reduces analgesic requirements, and provides good VAS scores with fewer complications following inguinal hernia surgery.

    To describe the CT findings of portal vein aneurysm in eight patients. All patients included in this study (two men and six women) underwent CT examinations between October 1996 and June1998. Of these eight, three were suffering from hepatic disease and portal hypertension. We determined the location, shape, size, and characteristics of the lesions, and the presence or absence of portal vein anomaly. Seven patients had intrahepatic portal vein aneurysm (at the umbilical portion of the left portal vein in five patients, between the transverse and umbilical portion of the left portal vein in one, and at the bifurcation of the anterior and posterior branch of the right portal vein in one), while extrahepatic portal vein aneurysm, at the confluence of the superior mesenteric and splenic vein was found in only one. Lesions were cyst-shaped in seven cases and saccular in one, and showed well-circumscribed, markedly enhanced mass, which communicated with the portal vein and/or gives off major branches. Portal vein anomaly, in which the right anterior segmental portal vein originated from the umbilical portion of the left portal vein, was seen in three patients. In all three, intrahepatic portal vein aneurysm was present at the umbilical portion of the left portal vein, and in one, the umbilical protion of the left portal vein was located to the right of the Cantlic line. CT examination can help reveal portal vein aneurysm by detecting a well-circumscribed, markedly enhanced mass which communicates with the portal vein and/or gives off major branches

    Full Text Available OBJECTIVE: to evaluate the role of fibrillar extracellular matrix components in the pathogenesis of inguinal hernias. METHODS: samples of the transverse fascia and of the anterior sheath of the rectus abdominis muscle were collected from 40 men aged between 20 and 60 years with type II and IIIA Nyhus inguinal hernia and from 10 fresh male cadavers (controls without hernia in the same age range. The staining technique was immunohistochemistry for collagen I, collagen III and elastic fibers; quantification of fibrillar components was performed with an image analysis processing software. RESULTS: no statistically significant differences were found in the amount of elastic fibers, collagen I and collagen III, and the ratio of collagen I / III among patients with inguinal hernia when compared with subjects without hernia. CONCLUSION: the amount of fibrillar extracellular matrix components did not change in patients with and without inguinal hernia.

    Full Text Available Inguinal hernia in children is one of the most common diseases requiring surgical treatment. There are two methods of surgical interventions for inguinal hernia in children: open and laparoscopic. In international clinical practice, open hernia repair is widely used due to the simplicity of the technique which does not require special tools. However, the percentage of complications and relapse frequency remain high when open hernia repair is performed. The article presents the analysis of the treatment results in 209 children with strangulated inguinal hernia who underwent open and laparoscopic surgery in the period from 2003 to 2014. The open hernia repair (Krasnobaev or Martynov technique was performed in 89 children. The following complications were registered: edema of the spermatic cord — in 34 patients, non-viable loop of the intestine — in 2; one child had a vermicular appendix with signs of striation in the hernial sac, 4 patients — a vermiform appendix with signs of inflammation. In 6 cases the contents of the hernial sac included the strand of the greater omentum, in 1 — the strand of the greater omentum with signs of acute ischemia. In 12 children, the hernial protrusion was absorbed to the abdominal, and therefore no revision was required. In 1 patient, the early postoperative period was complicated by peritonitis due to bowel wall necrosis. Laparoscopic hernioplasty was performed in 120 pediatric patients. The contents of the hernial sac in 86 cases included a loop of the small intestine, in 7 — an appendix and a site of the caecum, in 15 — the ovary and fallopian tubes, in 5 — the strand of the greater omentum. In 14 children, unobliterated internal inguinal rings previously not diagnosed were detected when examining the abdomen. Simultaneous appendectomy was performed when the cecum and the appendix were strangulated. Laparoscopic techniques omitting the disadvantages of an open repair method make it possible to

    Despite success with autologous tissue welding, laser welding of synthetic vascular prostheses has not been possible. The graft material appears inert and fails to allow the collagen breakdown and electrostatic bonding that results in tissue welding. To develop a laser welding system for graft material, we repaired glutaraldehyde-tanned human umbilical cord vein graft incisions using laser-assisted fibrinogen bonding (LAFB) technology. Modified umbilical vein graft was incised transversely (1.2 cm). Incisions were repaired using sutures, laser energy alone, or LAFB. For LAFB, indocyanine green dye was mixed with human fibrinogen and the compound applied with forceps onto the weld site prior to exposure to 808 nm diode laser energy (power density 4.8 W/cm 2). Bursting pressures for sutured repairs (126.6 +/- 23.4 mm Hg) were similar to LAFB anastomoses (111.6 +/- 55.0 mm Hg). No evidence of collateral thermal injury to the graft material was noted. In vivo evaluation of umbilical graft bonding with canine arteries demonstrates that LAFB can reliably reinforce sutured anastomoses. The described system for bonding graft material with laser exposed fibrinogen may allow creation or reinforcement of vascular anastomoses in procedures where use of autologous tissue is not feasible.

    Laparoscopic inguinal hernia repair has become a valid option for repair of an inguinal hernia. Due to there are several types of mesh fixation for laparoscopic repair of inguinal hernia. The study aims to assess and compare the efficacy of different types of mesh fixation for laparoscopic repair of inguinal hernia using network meta-analysis. We will systematically search PubMed, EMBASE the Cochrane library, and Chinese Biomedical Literature Database from their inception to March 2018. Randomized controlled trials (RCTs) that compared the effect of different types of mesh fixation for laparoscopic inguinal hernia repair will be included. The primary outcomes are chronic groin pain, incidence risk of hernia recurrence, and complications. Risk of bias assessment of the included RCTs will be conducted using to Cochrane risk of bias tool. A network meta-analysis will be performed using WinBUGS 1.4.3 software and the result figures will be generated using R x64 3.1.2 software and STATA V.12.0 software. Grading of Recommendations Assessment, Development and Evaluation (GRADE) will be used to assess the quality of evidence. The results of this study will be published in a peer-reviewed journal. Our study will generate evidence of laparoscopic repair of mesh fixation for adult patients with inguinal hernia and provide suggestions for clinical practice or guideline.

    Full Text Available Abstract Background As a main cause of mortality in developed countries, Coronary Artery Disease (CAD is known as silent killer with a considerable cost to be dedicated for its treatment. Coronary Artery Bypass Graft (CABG is a common remedy for CAD for which different blood vessels are used as a detour. There is a lack of knowledge about mechanical properties of human blood vessels used for CABG, and while these properties have a great impact on long-term patency of a CABG. Thus, studying these properties, especially those of human umbilical veins which have not been considered yet, looks utterly necessary. Methods Umbilical vein, as well as human Saphenous vein, are respectively obtained after cesarean and CABG. First, histological tests were performed to investigate different fiber contents of the samples. Having prepared samples carefully, force-displacement results of samples were rendered to real stress–strain measurements and then a fourth-order polynomial was used to prove the non-linear behavior of these two vessels. Results Results were analyzed in two directions, i.e. circumferentially and longitudinally, which then were compared with each other. The comparison between stiffness and elasticity of these veins showed that Saphenous vein’s stiffness is much higher than that of umbilical vein and also, it is less stretchable. Furthermore, for both vessels, longitudinal stiffness was higher than that of circumferential and in stark contrast, stretch ratio in circumferential direction came much higher than longitudinal orientation. Conclusion Blood pressure is very high in the region of aorta, so there should be a stiff blood vessel in this area and previous investigations showed that stiffer vessels would have a better influence on the flow of bypass. To this end, the current study has made an attempt to compare these two blood vessels’ stiffness, finding that Saphenous vein is stiffer than umbilical vein which is somehow as stiff as

    In this retrospective study, the survival rates of fingertip replantation with and without vein grafting were evaluated along with their postoperative functional and cosmetic results. One hundred twenty-one-fingertip amputations were performed in 103 patients between September 2002 and July 2007. Thirty-four amputated fingertips were replanted without vein grafting, while 87 amputated fingertips were replanted with vein grafting for arterial and/or venous repairs. The overall survival rates of the replantations with and without vein grafting were 90% (78/87) and 85% (29/34), respectively. The survival rates were 88% (36/41) with venous repair, 93% (25/27) with arterial repair, and 89% (17/19) with both. Nineteen patients without vein grafting and 48 patients with vein grafting had a follow-up period of more than one year. Good cosmetic and functional outcomes were observed in both groups of patients. The results show that vein grafting is a reliable technique in fingertip replantations, showing no significant difference (P > 0.05) in survival between those with and without vein grafting. Furthermore, no significant difference (P > 0.05) in survival was found between cases with vein grafts for arterial and/or venous repairs. In fingertip replantations with vein grafting, favorable functional and esthetic results can be achieved without sacrificing replantation survival. (c) 2009 Wiley-Liss, Inc.

    To evaluate the use of local anesthesia in tension-free hernioplasty in a local hospital. The study took place at Beijing Chaoyang Hospital Affiliated to Capital Medical University, Beijing, China during the period from January 2007 to May 2008. All 110 patients who had undergone inguinal hernia repair with mesh under local anesthesia were included in the study. To increase the homogeneity of the sample, we excluded umbilical hernia repairs, parastomal hernia repairs, non-elective procedures, procedures not involving mesh, and repairs performed concurrently with another surgical procedure. We performed a retrospective review of all 110 patients' data. The average operating time was 45 minutes (30-70 minutes), and the average hospital stay was 3-4 days. There was no postoperative mortality in this study. No surgical site infection occurred. Two patients (18%) that suffered from a moderate scrotal hematoma had recovered after extract injection therapy was applied. The duration of incisional pain was 2-3 days, and no patient required post-operative analgesia. During the follow-up, no recurrence occurred. The use of local anesthesia in inguinal hernia repair with tension-free hernioplasty is a safe and effective alternative for inpatient treatment. (aothor)

    Inguinal hernia repair is the most frequently performed surgical procedure in infants and children. Especially in premature infants, prevalence reaches up to 30% in coincidence with high rates of incarceration during the first year of life. These infants carry an increased risk of complications due to general anesthesia. Thus, spinal anesthesia is a topic of growing interest for this group of patients. We hypothesized that spinal anesthesia is a feasible and safe option for inguinal hernia repair in infants even at high risk and cases of incarceration. Between 2003 and 2013, we operated 100 infants younger than 6 months with inguinal hernia. Clinical data were collected prospectively and retrospectively analyzed. Patients were divided into two groups depending on anesthesia procedure (spinal anesthesia, Group 1 vs. general anesthesia, Group 2). Spinal anesthesia was performed in 69 infants, and 31 infants were operated in general anesthesia, respectively. In 7 of these 31 infants, general anesthesia was chosen because of lumbar puncture failure. Infants operated in spinal anesthesia were significantly smaller (54 ± 4 vs. 57 ± 4 cm; p = 0.001), had a lower body weight (4,047 ± 1,002 vs. 5,327 ± 1,376 g; p emergent incarcerated hernia repairs were performed in spinal anesthesia (p = 0.429). Spinal anesthesia is a feasible and safe option for inguinal hernia repair in infants, especially in high-risk premature infants and in cases of hernia incarceration.

    Central venous catheters are placed in approximately five million patients annually in the US. The preferred site of insertion is one with fewer risks and easier access. Although the right internal jugular vein is preferred, on occasion, the left internal jugular may have to be accessed. A patient was admitted for septic shock, cerebrovascular accident, and non-ST-segment elevation myocardial infarction. A central venous line was needed for antibiotic and vasopressor administration. Due to trauma from a fall to the right side and previously failed catheterization attempts at the left subclavian and femoral veins, the left internal jugular vein was accessed. On chest radiography for confirmation, the left internal jugular central venous catheter was seen projecting down the left paraspinal region. It did not take the expected course across the midline toward the right and into the superior vena cava (SVC). A review of a computed tomography (CT) scan of the chest with contrast done on a prior admission revealed a duplicated SVC on the left side that had not been reported in the original CT scan interpretation. A left-sided SVC is present in approximately 0.3% to 0.5% of the population, with 90% of these draining into the coronary sinus. During placements of central venous lines and pacemakers, irritation of the coronary sinus may result in hypotension, arrhythmia, myocardial ischemia, or cardiac arrest. A widened mediastinum can be an indication of a duplicated SVC. When attempting a left internal jugular vein central venous catheter placement, it is important to be aware of venous anomalies in order to prevent complications.

    The management of Incarcerated Inguinal Hernia (IIH) in children is challenging and may be associated with complications. We aimed to compare the outcomes of laparoscopic vs. open repair of IIH. With institutional ethical approval (09SG13), we reviewed the notes of 63 consecutive children who were admitted to a single hospital with the diagnosis of IIH between 2000 and 2008. Data are reported as median (range). Groups were compared by chi-squared or t-tests as appropriate. · Open repair (n=35): There were 21 children with right and 14 with left IIH. 2 patients also had contralateral reducible inguinal hernia. Small bowel resection was required in 2 children. · Laparoscopic repair (n=28): All children had unilateral IIH (19 right sided, 9 left sided). 15 children (54%) with no clinical evidence of contralateral hernia, had contralateral patent processus vaginalis at laparoscopy, which was also repaired. The groups were similar with regard to gender, age at surgery, history of prematurity, interval between admission and surgery, and proportion of patients with successful preoperative manual reduction. However, the duration of operation was longer in the laparoscopy group (p=0.01). Time to full feeds and length of hospital stay were similar in both groups. Postoperative follow-up was 3.5 months (1-36), which was similar in both groups. 5 patients in the group undergoing open repair had serious complications: 1 vas transaction, 1 acquired undescended testis, 2 testicular atrophy and 1 recurrence. The laparoscopic group had a single recurrence. Open repair of incarcerated inguinal hernia is associated with serious complications. The laparoscopic technique appears safe, avoids the difficult dissection of an oedematous sac in the groin, allows inspection of the reduced hernia content and permits the repair of a contralateral patent processus vaginalis if present. © Georg Thieme Verlag KG Stuttgart · New York.

    Full Text Available Purpose: To determine role and benefit of fibrin glue over tackers for mesh fixation in laparoscopic inguinal hernia repair. Backgroud: Mesh fixation by tackers may lead to many complications peroperatively like bleeding, increased hospital stay and overall more cost and later on chronic groin pain. Material and Methods: 60 inguinal hernia with age more than 18 years were taken and were divided in two groups; 30 patient group who underwent TAPP and 30 patient group who underwent TEPP. In 15 patients in both groups tackers were used and in other half fibrin glue was used for fixation of mesh using a 3mm catheter (Duplotip: Baxter Healthcare, which fits the Tisseel syringe. Results: The use of fibrin sealent has a distinct advantage in laparoscopic treatment of inguinal hernias compared with use of tackers as a method of mesh fixation. The use of fibrin sealant reduces the risk of post- and intraoperative complications, such as bleeding, seroma, chronic pain, has a lower incidence of postoperative neuralgia and provides an early faster return to social life. The recurrence rates do not vary much, but the operative time is slightly longer if the preparation time of the fibrin sealant is taken into consideration. In our study, we found a marginal difference in the cost of the two groups, fibrin sealant and stapled tackers. [Cukurova Med J 2015; 40(3.000: 457-465

  7. Diagnostic Laparoscopy as Decision Tool for Re-recurrent Inguinal Hernia Treatment Following Open Anterior and Laparo-Endoscopic Posterior Repair

    Full Text Available IntroductionThe guidelines of the international hernia societies recommend posterior repair in laparo-endoscopic technique for recurrent inguinal hernia after open anterior mesh repair and, conversely, open anterior repair for recurrence after laparo-endoscopic primary repair. Even when these guidelines are followed, already 1 year after repair a re-recurrence rate of 1–2% must be expected, with that rate rising further in the subsequent years. Accordingly, increasingly more patients with re-recurrence after anterior and posterior mesh implantation must be treated, which constitutes a problem that to date has been investigated in only very few studies. Hence, there are no well-founded recommendations. This paper now presents a number of case reports aimed at identifying the role of explorative laparoscopy as decision tool for re-recurrent inguinal hernia treatment.Patients and methodsBased on three case reports the role of explorative laparoscopy as decision tool for re-recurrent inguinal hernia treatment is presented below.ResultsIn all the three cases described explorative laparoscopy played a key role as decision tool when deciding how best to treat re-recurrence after anterior and posterior inguinal hernia repair. In one case severe adhesions after robotic prostatectomy and in another case correct placement of the mesh in the posterior plane, adhesions from the cecum to the groin region and no definitive finding of a re-recurrence resulted in an open repair. In the third case, an insufficient laparoscopic posterior mesh placement made the re-recurrent TAPP procedure relatively easy.ConclusionExplorative laparoscopy is an important decision tool for re-recurrent inguinal hernia treatment to minimize the risks of the procedure for the patients.

    Personal identification technology as security systems is developing rapidly. Traditional authentication modes like key; password; card are not safe enough because they could be stolen or easily forgotten. Biometric as developed technology has been applied to a wide range of systems. According to different researchers, vein biometric is a good candidate among other biometric traits such as fingerprint, hand geometry, voice, DNA and etc for authentication systems. Vein authentication systems can be designed by different methodologies. All the methodologies consist of matching stage which is too important for final verification of the system. Neural Network is an effective methodology for matching and recognizing individuals in authentication systems. Therefore, this paper explains and implements the Neural Network methodology for finger vein authentication system. Neural Network is trained in Matlab to match the vein features of authentication system. The Network simulation shows the quality of matching as 95% which is a good performance for authentication system matching.

    To characterize the ultrasonographic and clinical findings of inguinal hernia containing the ovary or omentum in girls. We studied 46 girls (49 cases) who were diagnosed with inguinal hernia on ultrasonography between March 2009 and December 2015. The ultrasonographic findings were retrospectively analyzed with respect to location, age at detection, contents of hernia, diameter of the canal of Nuck, and incidence of reducibility, incarceration and strangulation. The clinical findings included the number of cases that underwent operation, contents of hernia discovered during operation, and duration between ultrasonographic diagnosis and operation. The two groups in which inguinal hernia contained the ovary and omentum were statistically compared. Of the 49 cases, the contents of hernia were the ovary or tube in 14 cases, omentum in 32 cases, and bowel in 3 cases. The ovarian herniation group was significantly younger (10.1 months vs. 4.9 years, p < 0.001), had a lower incidence of reducibility (n = 3 vs. n = 29, p < 0.001), higher incidence of incarceration (n = 4 vs. n = 0, p = 0.006), and a shorter duration between ultrasonographic diagnosis and operation (5.7 days vs. 55.8 days, p = 0.032) than the omental herniation group. The ovarian herniation group was younger, had a lower incidence of reducibility, higher incidence of incarceration, and a shorter duration between ultrasonographic diagnosis and operation.

  11. Absence of Middle Hepatic Vein Combined with Retro-Aortic Left Renal Vein: a Very Rare Case Report

    Directory of Open Access Journals (Sweden)

    Sezer Akçer

    2012-06-01

    Full Text Available The hepatic and renal veins drain into the inferior vena cava. The upper group of hepatic veins consists of three veins which extend to the posterior face of the liver to join the inferior cava. The left renal vein passes anterior to the aorta just below the origin of the superior mesenteric artery. We detected a variation in the hepatic and renal veins in a multislice CT angiogram of a nine-year-old male patient in the Radiology Department of Afyon Kocatepe University Medical School. The upper group hepatic veins normally drains into the inferior vena cava as three separate trunks, namely the right, left and middle. In our case, we found that only the right and left hepatic veins existed and the middle hepatic vein was absent. Furthermore, the left renal vein, which normally passes anterior to the abdominal aorta, was retro-aortic. Left renal vein variations are of great importance in planning retroperitoneal surgery and vascular interventions. Knowledge of a patient’s hepatic vein and renovascular anatomy and determining their variations and anomalies are of critical importance to abdominal operations, transplantations and preoperative evaluation of endovascular interventions.

    Laparoscopic TAPP inguinal hernia repair is an established alternative to open hernia repair, which offers equivalent outcomes with less postoperative pain and faster recovery. Unfortunately, it remains technically challenging, requiring advanced laparoscopic skills which have limited its popularity among surgeons. The robotic platform has the potential to overcome these challenges. The objective of this study was to examine the long-term quality of life and outcomes following robotic assisted TAPP inguinal hernia repair, since these data have not been reported up to now. From October 2012 to October 2015, 159 inguinal hernias in 82 consecutive patients were repaired with 3D mesh (BARD) using da Vinci Si Surgical System (Intuitive Surgical, Sunnyvale, CA, USA). The patients' demographics and intraoperative data were documented. Patients were seen 2 and 6 weeks after the surgery and the complications were recorded. Patients were assessed 6 weeks after the surgery by a survey using a universal pain assessment tool to document their post-operative pain, narcotic use and time of return to work and exercise. A modified short form 12 (SF 12) was also sent out to the patients 12-36 months after the surgery to measure their health-related quality of life prior to surgery and at the 12- to 36-month follow-up, and to document any evidence of recurrence. Postoperative health-related quality of life scores were compared to the pre-operative baseline quality of life scores using the unpaired t test. Over the course of 3 years, 159 robotic assisted TAPP inguinal hernia repair were performed in 82 patients, 73 men and 9 women by one surgeon as an outpatient basis. The mean age was 53 and mean body mass index was 26. There were no intraoperative complications or conversions. The average operative time was 99 min. Four patients developed urinary retention post-operatively and one patient developed postoperative bowel obstruction requiring laparoscopic lysis of adhesion with no

    The management of cosmetic vein problems requires a very different approach than that for the majority of most other vascular disorders that occur in a vascular surgery practice. This article focuses on the business aspects of a cosmetic vein practice, with particular attention to the uniqueness of these issues. Managing patient expectations is critical to the success of a cosmetic vein practice. Maneuvering within the insurance can be difficult and frustrating for both the patient and the practice. Practices should use cost accounting principles to evaluate the success of their vein work. Vein surgery--especially if performed within the office--can undergo an accurate break-even analysis to determine its profitability.

    With current technological advancement and availability of synthetic materials used in inguinal hernia repair, a recurrence after first intervention is not a common and important adverse event. On the other hand, however, some patients complain about chronic pain of the operated site after surgeries using a polypropylene mesh. Many patients are constrained to a prolonged use of analgesics and increased frequency of control visits, which may eventually result in loss of trust in the operator. Every surgical intervention is associated with the risk of immediate or delayed complications. Genitofemoral neuralgia is associated with dysfunction of peripheral nerves passing through the inguinal canal or the surrounding tissue and it is a chronic, troublesome and undesired complication of an inguinal hernia repair. The possibility of minimizing chronic inguinal pain by proper management during herniorraphy should be considered in all cases of an inguinal canal reconstruction. The aim of the study was to investigate whether an intraoperative injection of 0.5% bupivacaine into the operated site (preemptive analgesia) has an influence on the postoperative pain assessed on the day of operation as well as the 1st and 2nd postoperative day after Lichtenstein hernioplasty of an inguinal, scrotal or recurrent hernia. In the studied population, we attempted to identify risk factors affecting pain level after surgical repair of an inguinal, scrotal or recurrent hernia. During the period between December 2015 and May 2016, 133 patients with preoperative diagnosis of an inguinal (81.95%, n=109), scrotal (13.53%, n=18) or recurrent hernia (4.51%, n=6) underwent an elective intervention and were randomly allocated to the group, which intraoperatively received 20 mL of 0.5% bupivacaine locally in selected anatomical points of the inguinal canal. In the group with preoperative diagnosis of an inguinal hernia, this intervention was applied in 56.88% of cases (n=62). In the case of scrotal

    The main complication of surgery for inguinal hernia is chronic postoperative pain. This is often reported following the Lichtenstein procedure. A new, open surgical technique for the repair of inguinal hernia has been developed. This procedure is called the transrectus sheath preperitoneal procedure (TREPP). At TREPP a lightweight mesh with a ring made of memory metal is introduced into the preperitoneal space through the transrectus sheath. The first results of this operative technique are very promising: short operation time, short learning curve and not many patients with chronic postoperative pain. In a randomised, multi-centre study which will start mid-2013 (ISRCTN18591339), the TREPP procedure is compared with the transinguinal preperitoneal procedure. The primary outcome measure of this study is chronic postoperative pain.

  2. Arabidopsis thaliana Ei-5: Minor Vein Architecture Adjustment Compensates for Low Vein Density in Support of Photosynthesis.

    An Arabidopsis thaliana accession with naturally low vein density, Eifel-5 (Ei-5), was compared to Columbia-0 (Col-0) with respect to rosette growth, foliar vein architecture, photosynthesis, and transpiration. In addition to having to a lower vein density, Ei-5 grew more slowly, with significantly lower rates of rosette expansion, but had similar capacities for photosynthetic oxygen evolution on a leaf area basis compared to Col-0. The individual foliar minor veins were larger in Ei-5, with a greater number of vascular cells per vein, compared to Col-0. This compensation for low vein density resulted in similar values for the product of vein density × phloem cell number per minor vein in Ei-5 and Col-0, which suggests a similar capacity for foliar sugar export to support similar photosynthetic capacities per unit leaf area. In contrast, the product of vein density × xylem cell number per minor vein was significantly greater in Ei-5 compared to Col-0, and was associated not only with a higher ratio of water-transporting tracheary elements versus sugar-transporting sieve elements but also significantly higher foliar transpiration rates per leaf area in Ei-5. In contrast, previous studies in other systems had reported higher ratios of tracheary to sieve elements and higher transpiration rate to be associated with higher - rather than lower - vein densities. The Ei-5 accession thus further underscores the plasticity of the foliar vasculature by illustrating an example where a higher ratio of tracheary to sieve elements is associated with a lower vein density. Establishment of the Ei-5 accession, with a low vein density but an apparent overcapacity for water flux through the foliar xylem network, may have been facilitated by a higher level of precipitation in its habitat of origin compared to that of the Col-0 accession.

METHODS:: Using Danish birth cohorts from 1986-1990, we compared the academic performance of all children who had undergone inguinal hernia repair in infancy to a randomly selected, age-matched 5% population sample. Primary analysis...... found no evidence that a single, relatively brief anesthetic exposure in connection with hernia repair in infancy reduced academic performance at age 15 or 16 yr after adjusting for known confounding factors. However, the higher test score nonattainment rate among the hernia group could suggest...... repair in infancy. A randomly selected, age-matched 5% population sample consists of 14,575 individuals. Although the exposure group performed worse than the control group (average score 0.26 lower; 95% CI, 0.21-0.31), after adjusting for known confounders, no statistically significant difference (-0...

    Full Text Available Abstract Introduction Lower Spigelian hernia is a very rare entity. The clinical findings are similar to those of inguinal hernias and in many cases may be misdiagnosed. In the literature, only a few references to this entity have been reported in children. To the best of our knowledge, this is the first case report of a lower Spigelian hernia in a child who presented with an acute painful scrotum. Case presentation We discuss the case of a 6-year-old Greek boy who presented to our emergency department complaining of severe pain in the left inguinal area and scrotum. The acute painful swelling started suddenly, without any obvious cause. The initial diagnosis was incarcerated inguinal hernia which was reduced with difficulty. Five days later, the patient still experienced mild pain during palpation and he was operated on. During the operation, a large lower Spigelian hernia was revealed and reconstructed. Conclusion Although Spigelian hernias are rare in children and difficult to diagnose, physicians should be aware of them and include them in the differential diagnosis.

    We aimed to report the outcomes of inguinal hernia repair performed at Tan Tock Seng Hospital and compare them with those performed at dedicated hernia centres. We retrospectively analysed the medical records and telephone interviews of 520 patients who underwent inguinal hernia repair in 2010. The majority of the patients were male (498 [95.8%] men vs. 22 [4.2%] women). The mean age was 59.9 ± 15.7 years. Most patients (n = 445, 85.6%) had unilateral hernias (25.8% direct, 64.3% indirect, 9.9% pantaloon). The overall recurrence rate was 3.8%, with a mean time to recurrence of 12.0 ± 8.6 months. Risk factors for recurrence included contaminated wounds (odds ratio [OR] 50.325; p = 0.004), female gender (OR 8.757; p = 0.003) and pantaloon hernias (OR 5.059; p = 0.013). Complication rates were as follows: chronic pain syndrome (1.2%), hypoaesthesia (5.2%), wound dehiscence (0.4%), infection (0.6%), haematoma/seroma (4.8%), urinary retention (1.3%) and intraoperative visceral injury (0.6%). Most procedures were open repairs (67.7%), and laparoscopic repair constituted 32.3% of all the inguinal hernia repairs. Open repairs resulted in longer operating times than laparoscopic repairs (86.6 mins vs. 71.6 mins; p hospital stays (2.7 days vs. 0.7 days; p = 0.020) and a higher incidence of post-repair hypoaesthesia (6.8% vs. 1.8%; p = 0.018). However, there were no significant differences in recurrence or other complications between open and laparoscopic repair. A general hospital with strict protocols and teaching methodologies can achieve inguinal hernia repair outcomes comparable to those of dedicated hernia centres.

    Objective: To compare post operative wound infection frequency after inguinal hernia repair with polypropylene and polyester mesh using standard Lichtenstein hernioplasty technique. Study Design: Randomized controlled trial. Place and Duration: This study was conducted at general surgery department CMH/MH Rawalpindi from 8th April 2007 to 1st Jan 2008 over a period of 09 months. Patients and Materials: Sixty patients received through outpatient department with diagnosis of inguinal hernia satisfying inclusion/exclusion criteria were included. Patients were divided into two groups randomly. Group 1 included those patients in whom polypropylene mesh was used while group II patients were implanted with polyester mesh. Demographic as well as data concerning post operative wound infection was collected and analyzed. Results: Fifty seven patients (95%) were males while remaining (05%) were females. Mean age in group I was 41.17+-9.99 years while in group II was 41.47+-9.79 years (p=0.907). One patient (3.3%) in each group developed wound infection diagnosed by clinical evidence of pain at wound site, redness, induration and purulent discharge. Conclusion: There is no difference in post operative wound infection rate after inguinal Lichtenstein hernioplasty using either polypropylene or polyester mesh. (author)

  8. Difficulty of MRI based identification of lesion age by acute infra-tentorial ischemic stroke.

    Full Text Available Systemic thrombolysis in acute ischemic stroke is restricted to the 4.5 h time window. Many patients are excluded from this treatment because symptom onset is unknown. Magnetic resonance imaging (MRI studies have shown that stroke patients presenting with acute supra-tentorial diffusion-weighted imaging (DWI lesions that do not have matching lesions on fluid attenuated inversion recovery (FLAIR are likely to be within a 4.5 hour time window. This study examines the DWI-FLAIR mismatch in infra-tentorial stroke.This was a retrospectively conducted substudy of the "1000+" study; a prospective, single-center observational study (http://clinicaltrials.gov; NCT00715533. Fifty-six patients with infra-tentorial stroke confirmed by MRI and known symptom onset who underwent the scan within 24 h after symptom onset were analysed. Two neurologists blinded to clinical information separately rated the DWI lesion visibility on FLAIR. Lesion volume, relative signal intensities of DWI and relative apparent diffusion coefficient values were determined.Regarding baseline characteristics our study population had a median age of 66 years, a median time from symptom onset to MRI of 616.5 minutes, a median NIHSS of 3 and a median DWI lesion volume of 0.26 ml. A negative FLAIR allocated patients to a time window under 4.5 h correctly with a sensitivity of 55% and a specificity of 61%, a positive predictive value of 44% and a negative predictive value of 71%. FLAIR positivity decreased with age (p = 0.018, and showed no significant correlation to lesion volume (p = 0.145.In our study the DWI-FLAIR-Mismatch does not help to reliably identify patients within 4.5 h of symptom onset in acute ischemic infra-tentorial stroke. Thus therapeutical decisions based on the DWI-FLAIR mismatch estimation of time from onset cannot be recommended in patients with infra-tentorial stroke.

    Society for Vascular Surgery practice guidelines for the medical treatment of intermittent claudication give a GRADE 1A recommendation for smoking cessation. Active smoking is therefore expected to be low in patients suffering from intermittent claudication selected for vascular surgical intervention. The aim of this study is to evaluate the prevalence of smoking in patients undergoing intervention for intermittent claudication at the national level and to determine the relationship between smoking status and intervention. The Vascular Quality Initiative (VQI) registries for infra-inguinal bypass, supra-inguinal bypass, and peripheral vascular intervention (PVI) were queried to identify patients who underwent invasive treatment for intermittent claudication. Patient factors, procedure type (bypass versus PVI), and level of disease (supra-inguinal versus infra-inguinal) were evaluated for associations with smoking status (active smoking or nonsmoking) by univariate and covariate analysis. Between 2010 and 2015, 101,055 procedures were entered in the 3 registries, with 40,269 (40%) performed for intermittent claudication. Complete data for analysis were present in 37,632 cases. At the time of intervention, 44% of patients were active smokers, with wide variation by regional quality group (16-53%). In covariate analysis, active smoking at treatment was associated with age smoking status. During follow-up, 36% of patients had quit smoking. Predictors of smoking cessation included age ≥70 years (RR 1.45), ABI ≥0.9 (RR 1.12), and bypass procedures (RR 1.22). At the time of treatment, 44% of patients undergoing intervention for intermittent claudication in the VQI were active smokers and there was a wide regional variation. Prevalence of active smoking was greater in the presence of younger age, fewer comorbidities, lower ABI, and supra-inguinal disease. Type of procedure performed, and in turn level of invasiveness required, did not appear to be influenced by smoking

    Full Text Available Patients with gastroesophageal reflux disease may have disturbances of gastric motility, which could play a role in the pathophysiology of the disease. Recent studies have suggested that the gastric region just below the gastroesophageal junction may have a distinct physiological behavior. We determined whether patients with gastroesophageal reflux disease have abnormal residence of food in the infra-junctional portion of the stomach after ingesting a liquid nutrient meal. Fasted adult patients with reflux disease (N = 11 and healthy volunteers (N = 10 ingested a liquid meal (320 ml; 437 kcal labeled with 99m technetium-phytate and their total gastric emptying half-time and regional emptying from the stomach infra-junctional region were determined. In 8 patients, episodes of postprandial acidic reflux to the esophagus were measured for 2 h using pH monitoring. There were no differences between reflux patients and controls regarding total gastric emptying time (median: 68 min; range: 39-123 min vs 65 min and 60-99 min, respectively; P > 0.50. Food residence in the infra-junctional area was similar for patients and controls: 23% (range: 20-30 vs 27% (range: 19-30%; P = 0.28 and emptying from this area paralleled total gastric emptying (Rs = 0.79; P = 0.04. There was no correlation between residence of food in the infra-junctional area and episodes of gastroesophageal reflux (Rs = 0.06; P = 0.88. We conclude that it is unlikely that regional motor disturbances involving the infra-junctional region of the stomach play a relevant role in the pathogenesis of acidic gastroesophageal reflux.

    Objective: To evaluate the feasibility of percutaneous transsplenic portal vein catheterization (PTSPC). Methods: Thirty patients with portal hypertension underwent gastroesophageal variceal embolization via PTSPC route, 2 of which simultaneously underwent portal vein stenting. This study included the patients with portal venous obstruction (tumor embolus or thrombus) or the patients with serious liver atrophy caused by liver cirrhosis. The patients who had severe coagulation insufficiency (with prothrombin time > 20 s) were excluded. Of the 30 patients, 17 had primary hepatocellular carcinoma with main portal venous tumor embolus, 13 had cirrhosis with severe liver atrophy and (or)slight or moderate ascite. Before this study, all of 30 patients had a history of variceal bleeding, and 16 patients had a normal coagulation level, 10 patients had a mildly prolonged prothrombin time (14-17 s), 4 patients had a moderately prolonged prothrombin time (18-20 s). All of 30 patients underwent upper abdomen CT enhanced scanning before this procedure, and the site, direction, and depth of splenic vein branch puncture were decided by CT images. The technology of PTSPC, procedure-related complications, and its clinical application were retrospectively analyzed. Results: PTSPC was performed successfully in 28 of 30 patients. Two cases failed because of a small intrasplenic vein. Procedure-related complications occurred in 6 patients (20.0%), which had decrease of hemoglobin concentration (15-50 g/L). Four of them needed blood transfusion. In the six patients, one patient (3.3%) with abdominal cavity hemorrhage had a serious drop of blood pressure 2 hours after procedure, whose clinical symptoms were relieved after four units of packed RBC and a great quantity of fluid were transfused. Twenty-eight patients whose PTSPC were successfully performed underwent variceal embolization, 2 of them were placed with portal vein covered stents. During a median follow-up period of 6 months

    We investigated the patient characteristic factors that correlate with identification of i.v. cannulation sites with normal eyesight. We evaluated a new infrared vein finding (VF) technology device in identifying i.v. cannulation sites. Each subject underwent two observations: one using the conventional method (CM) of normal, unassisted eyesight and the other with the infrared VF device, VueTek's Veinsite™ (VF). A power analysis for moderate effect size (β=0.95) required 54 samples for within-subject differences. Patient characteristic profiles were obtained from 384 subjects (768 observations). Our sample population exhibited an overall average of 5.8 [95% confidence interval (CI) 5.4-6.2] veins using CM. As a whole, CM vein visualization were less effective among obese [4.5 (95% CI 3.8-5.3)], African-American [4.6 (95% CI 3.6-5.5 veins)], and Asian [5.1 (95% CI 4.1-6.0)] subjects. Next, the VF technology identified an average of 9.1 (95% CI 8.6-9.5) possible cannulation sites compared with CM [average of 5.8 (95% CI 5.4-6.2)]. Seventy-six obese subjects had an average of 4.5 (95% CI 3.8-5.3) and 8.2 (95% CI 7.4-9.1) veins viewable by CM and VF, respectively. In dark skin subjects, 9.1 (95% CI 8.3-9.9) veins were visible by VF compared with 5.4 (95% CI 4.8-6.0) with CM. African-American or Asian ethnicity, and obesity were associated with decreased vein visibility. The visibility of veins eligible for cannulation increased for all subgroups using a new infrared device.

In this study, we developed a tissue-engineered mesh (TEM by seeding autologous bone marrow-derived mesenchymal stem cells onto nanosized fibers decellularized aorta (DA. DA was achieved by decellularizing the aorta sample sequentially with physical, mechanical, biological enzymatic digestion, and chemical detergent processes. The tertiary structure of DA was constituted with micro-, submicro-, and nanosized fibers, and the original strength of fresh aorta was retained. Inguinal hernia rabbit models were treated with TEMs or acellular meshes (AMs. After implantation, TEM-treated rabbit models showed no hernia recurrence, whereas AM-treated animals displayed bulges in inguinal area. At harvest, TEMs were thicker, have less adhesion, and have stronger mechanical strength compared to AMs (P<0.05. Moreover, TEM showed better cell infiltration, tissue regeneration, and neovascularization (P<0.05. Therefore, these cell-seeded DAs with nanosized fibers have potential for use in inguinal hernioplasty.

    With improvements in neonatal intensive care, more preterm infants are surviving the neonatal period and presenting for surgery in early infancy. Inguinal hernia is the most common condition requiring early surgery, appearing in 38% of infants whose birth weight is between 751 grams and 1000 grams. Approximately 20% to 30% of otherwise healthy preterm infants having general anaesthesia for inguinal hernia surgery at a postmature age have at least one apnoeic episode within the postoperative period. Research studies have failed to adequately distinguish the effects of apnoeic episodes from other complications of extreme preterm gestation on the risk of brain injury, or to investigate the potential impact of postoperative apnoea upon longer term neurodevelopment. In addition to episodes of apnoea, there are concerns that anaesthetic and sedative agents may have a direct toxic effect on the developing brain of preterm infants even after reaching postmature age. It is proposed that regional anaesthesia may reduce the risk of postoperative apnoea, avoid the risk of anaesthetic-related neurotoxicity and improve neurodevelopmental outcomes in preterm infants requiring surgery for inguinal hernia at a postmature age. To determine if regional anaesthesia reduces postoperative apnoea, bradycardia, the use of assisted ventilation, and neurological impairment, in comparison to general anaesthesia, in preterm infants undergoing inguinal herniorrhaphy at a postmature age. The following databases and resources were searched: the Cochrane Central Register of Controlled Trials (CENTRAL, The Cochrane Library, 2015, Issue 2), MEDLINE (December 2002 to 25 February 2015), EMBASE (December 2002 to 25 February 2015), controlled-trials.com and clinicaltrials.gov, reference lists of published trials and abstracts published in Pediatric Research and Pediatric Anesthesia.

Con el presente trabajo se buscó dar respuesta a algunas controversias en torno de la reparación de las hernias inguinales, así como realizar una valoración sobre el dolor posoperatorio y analizar los costos de las técnicas de reparación protésicas y la técnica que refuerza la pared posterior del canal inguinal con una franja aponeurótica pediculada del músculo oblicuo mayor. MÉTODOS. Se realizó un estudio prospectivo aleatorio de 836 pacientes con hernia inguinal, operados entre septiembre del 2001 y diciembre del 2007. A un grupo se le practicó una hernioplastia anterior con malla y al otro la técnica de Mohan P. Desarda, la cual consiste en una herniorrafia sin malla. RESULTADOS. Ambos grupos de pacientes fueron comparables, sin diferencias con respecto a la edad, la localización y el tipo de hernia. El tiempo quirúrgico fue menor en la hernioplastia con malla y no hubo diferencias significativas en cuanto al dolor durante el primer y tercer día del posoperatorio, pero en el grupo de la hernioplastia éste fue superior al quinto día. En tres pacientes hubo rechazo a la malla de polipropileno. CONCLUSIONES. La técnica de Desarda, al no utilizar malla, fue más económica que la hernioplastia con malla; esta diferencia fue estadísticamente significativa.INTRODUCTION: With present paper we gave response to some controversies around the repair of inguinal hernias as well as to make a valuation on postoperative pain and to analyze the costs of prosthetic repair techniques and the technique reinforcing the posterior wall of inguinal channel with a pediculate aponeurotic band of major obliquus muscle.

    This study presents a detailed description of the distribution, diameters and drainage patterns of hepatic veins on the basis of the corrosion cast analysis in 18 dogs. We classified the hepatic veins in three main groups: the right hepatic veins of the caudate process and right lateral liver lobe, the middle hepatic veins of the right medial and quadrate lobes and the left hepatic veins of both left liver lobes and the papillary process. The corrosion cast study showed that the number of the veins in the Nomina Anatomica Veterinaria and most anatomical textbooks is underestimated. The number of various-sized hepatic veins of the right liver division ranged from 3 to 5 and included 1 to 4 veins from the caudate process and 2 to 4 veins from the right lateral liver lobe. Generally, in all corrosion casts, one middle-sized vein from the right part of the right medial lobe, which emptied separately in the caudal vena cava, was established. The other vein was a large-sized vein from the remainder of the central division, which frequently joined the common left hepatic vein from the left liver lobes. The common left hepatic vein was the largest of all the aforementioned hepatic veins.

  4. Image Quality Enhancement Using the Direction and Thickness of Vein Lines for Finger-Vein Recognition

    2012-10-01

    Full Text Available On the basis of the increased emphasis placed on the protection of privacy, biometric recognition systems using physical or behavioural characteristics such as fingerprints, facial characteristics, iris and finger-vein patterns or the voice have been introduced in applications including door access control, personal certification, Internet banking and ATM machines. Among these, finger-vein recognition is advantageous in that it involves the use of inexpensive and small devices that are difficult to counterfeit. In general, finger-vein recognition systems capture images by using near infrared (NIR illumination in conjunction with a camera. However, such systems can face operational difficulties, since the scattering of light from the skin can make capturing a clear image difficult. To solve this problem, we proposed new image quality enhancement method that measures the direction and thickness of vein lines. This effort represents novel research in four respects. First, since vein lines are detected in input images based on eight directional profiles of a grey image instead of binarized images, the detection error owing to the non-uniform illumination of the finger area can be reduced. Second, our method adaptively determines a Gabor filter for the optimal direction and width on the basis of the estimated direction and thickness of a detected vein line. Third, by applying this optimized Gabor filter, a clear vein image can be obtained. Finally, the further processing of the morphological operation is applied in the Gabor filtered image and the resulting image is combined with the original one, through which finger-vein image of a higher quality is obtained. Experimental results from application of our proposed image enhancement method show that the equal error rate (EER of finger-vein recognition decreases to approximately 0.4% in the case of a local binary pattern-based recognition and to approximately 0.3% in the case of a wavelet transform

He presented one episode of painless gross hematuria. Laboratory and imaging studies excluded any significant lesion in the urological organs. Abdominal CT scan demonstrated a heterogeneous neoplasm of 4 cm in size in the left paravesical area that was retrieved laparoscopically. Abdominal CT and clinical suspicion are helpful for diagnosis. Laparoscopy may be used to confirm the diagnosis and to remove the retained surgical gauze, and considered as an alternative therapy for some selected patients.

    Understanding of the anatomy of the hepatic vein is important in manipulation for transplantation of the liver, hepatectomy and the treatment of hepatic trauma with avulsion of the hepatic vein. Demonstrated of the inferior right hepatic vein (IRHV) is also important; in some cases of hepatocellular carcinoma, thrombus can be seen in the IRHV; in primary Budd-Chiari syndrome, the IRHV is main draining vein; during hepatectomy, the postero-inferior segment of the right lobe and draining IRHV can be preserved. For some 10 months ultrasound examination was done in a total of 124 patients with normal liver function with special emphasis on the hepatic vein, their branches, and the IRHV, and analysed in terms of branching pattern and relative size of the hepatic vein and the detection rate of the IRHV.

    Full Text Available Primary pelvic tumors are relatively rare, representing no more than 5% of primary bone tumors. We presented a case of a chondrosarcoma of the superior pubic ramus initially managed as an inguinal hernia and then operated under oncological principles. Special attention is attributed to the importance for the correct diagnosis and surgical treatment given the low efficacy of adjuvant treatments for this type of neoplasia.

    To analyze failure modes in a high-volume adrenal vein sampling (AVS) practice in an effort to identify preventable causes of nondiagnostic sampling. A retrospective database was constructed containing 343 AVS procedures performed over a 10-year period. Each nondiagnostic AVS procedure was reviewed for failure mode and correlated with results of any repeat AVS. Data collected included selectivity index, lateralization index, adrenalectomy outcomes if performed, and details of AVS procedure. All AVS procedures were performed after cosyntropin stimulation, using sequential technique. AVS was nondiagnostic in 12 of 343 (3.5%) primary procedures and 2 secondary procedures. Failure was right-sided in 8 (57%) procedures, left-sided in 4 (29%) procedures, bilateral in 1 procedure, and neither in 1 procedure (laboratory error). Failure modes included diluted sample from correctly identified vein (n = 7 [50%]; 3 right and 4 left), vessel misidentified as adrenal vein (n = 3 [21%]; all right), failure to locate an adrenal vein (n = 2 [14%]; both right), cosyntropin stimulation failure (n = 1 [7%]; diagnostic by nonstimulated criteria), and laboratory error (n = 1 [7%]; specimen loss). A second AVS procedure was diagnostic in three of five cases (60%), and a third AVS procedure was diagnostic in one of one case (100%). Among the eight patients in whom AVS ultimately was not diagnostic, four underwent adrenalectomy based on diluted AVS samples, and one underwent adrenalectomy based on imaging; all five experienced improvement in aldosteronism. A substantial percentage of AVS failures occur on the left, all related to dilution. Even when technically nondiagnostic per strict criteria, some "failed" AVS procedures may be sufficient to guide therapy. Repeat AVS has a good yield. Copyright © 2014 SIR. Published by Elsevier Inc.

    To evaluate the usefulness of placement of self-expandable stents in hemodialytic shunt-related subclavian vein stenosis. Self-expandable metallic stent was placed in nine patients with hemodialytic shunt-related subclavian vein stenosis. In seven cases, angioplasty was attempted before stent placement; in five, stents were placed immediately after failed angioplasty; and in two, due to restenosis after angioplasty. Procedures involved a 10mm diameter, 7-10cm length Wallstent in eight cases, and a 10mm diameter, 8cm length Hanaro stent in one. In all cases, clinical follow-up, which included physical examination and the measurement of venous resistance pressure during hemodialysis, was performed. The follow-up period was between 5 months and 1 year 7 months. Repeated intervention was performed if restenosis was detected. The stenotic sites were in eight cases the site of a previous subclavian venous line, and in one, the site of anatomic narrowing at the thoracic inlet of the subclavian vein. The technical success rate was 100%;a resulting complication was stent migration into the right atrium in one case in which a Hanaro stent had been used; this was removed by snaring. During follow-up of the eight patients in whon stent placement was successful, restenosis developed in three cases. This occurred during the 7th, 8th, and 15th month, respectively. Two such cases were treated by balloon dilatation. In hemodialytic shunt-related subclavian vein stenosis, treatment involving the use of a self-expandable metallic stent is useful, especially for treating a lesion which has not responded to angioplasty with a high patency rate.

    Inguinal hernia repair is the most common general surgery operation performed globally. However, the adoption of tension-free hernia repair with mesh has been limited in low-income settings, largely due to a lack of technical training and resources. The present study evaluates the impact of a 2-day training course instructing use of polypropylene mesh for inguinal hernia repair on the practice patterns of sub-Saharan African physicians. A surgical training course on tension-free mesh repair of hernias was provided to 16 physicians working in rural Ghanaian and Liberian hospitals. Three physicians were requested to prospectively record all their inguinal hernia surgeries, performed with or without mesh, during the 14-month period following the training. Demographic variables, diagnoses, and complications were collected by an independent data collector for mesh and non-mesh procedures. Surgery with mesh increased significantly following intervention, from near negligible levels prior to the training to 8.1 % of all inguinal hernia repairs afterwards. Mesh repair accounted for 90.8 % of recurrent hernia repairs and 2.9 % of primary hernia repairs after training. Overall complication rates between mesh and non-mesh procedures were not significantly different (p = 0.20). Three physicians who participated in an intensive education course were routinely using mesh for inguinal hernia repair 14 months after the training. This represents a significant change in practice pattern. Complication rates between patients who underwent inguinal hernia repairs with and without mesh were comparable. The present study provides evidence that short-term surgical training initiatives can have a substantial impact on local healthcare practice in resource-limited settings.

    During its transit through the umbilicus structural changes occur in the thick wall of the extra-abdominal segment of the umbilical vein whereby the components of the intra-abdominal segment acquire an essentially longitudinal direction and become arranged in fibro-elastic and fibro-muscular zones. The vein lumen becomes largely obliterated by asymmetrical proliferation of loose subendothelial conective tissue. The latter forms a new inner zone within which a small segment of the lumen persists in an eccentric position. This residual lumen transmits blood to the portal system from paraumbilical and systemic sources, and is retained in the upper part of the vein, even in old age. A similar process of lumen closure is observed in the ductus venosus. In early childhood the lower third of the vein undergoes breakdown, with fatty infiltration, resulting in its complete division into vascular fibro-elastic strands, and in old age some breakdown occurs in the outermost part of the wall of the upper two thirds. The paraumbilical veins are thick-walled and of similar structure to the umbilical vein. Together they constitute an accessory portal system which is confined between the layers of the falciform ligament and is in communication with the veins of the ventral abdominal wall. The constituents form an ascending series, namely, Burow's veins, the umbilical vein, and Sappey's inferior and superior veins. The main channel of Sappey's inferior veins may be the remnant of the right umbilical vein since it communicates with the right rectus sheath and often communicates directly with the portal system within the right lobe of the liver. The results are of significance in relation to clinical usage of the umbilical vein.

  15. Idiopathic Bilateral External Jugular Vein Thrombosis.

    Hindi, Zakaria; Fadhel, Ehab

    2015-08-20

    Vein thrombosis is mainly determined by 3 factors, which constitute a triad called Virchow's triad: hypercoagulability, stasis, and endothelial injury. Venous thrombosis commonly occurs in the lower extremities since most of the blood resides there and flows against gravity. The veins of the lower extremities are dependent on intact valves and fully functional leg muscles. However, in case of valvular incompetency or muscular weakness, thrombosis and blood stasis will occur as a result. In contrast, the veins of the neck, specially the jugulars, have distensible walls which allow flexibility during respiration. In addition, the blood directly flows downward towards the heart. Nevertheless, many case reports mentioned the thrombosis of internal jugular veins and external jugular veins with identified risk factors. Jugular vein thrombosis has previously been associated in the literature with a variety of medical conditions, including malignancy. This report is of a case of idiopathic bilateral external jugular vein thrombosis in a 21 year-old male construction worker of Southeast Asian origin with no previous medical history who presented with bilateral facial puffiness of gradual onset over 1 month. Doppler ultrasound and computed tomography were used in the diagnosis. Further work-up showed no evidence of infection or neoplasia. The patient was eventually discharged on warfarin. The patient was assessed after 6 months and his symptoms had resolved completely. Bilateral idiopathic external jugular veins thrombosis is extremely rare and can be an indicator of early malignancy or hidden infection. While previous reports in the literature have associated jugular vein thrombosis with malignancy, the present case shows that external jugular vein thrombosis can also be found in persons without malignancy.

    There has been increasing interest within the European sports medicine community regarding the etiology and treatment of groin pain in the athlete. Groin pain is most commonly caused by musculotendinous strains of the adductors and other muscles crossing the hip joint, but may also be related to abdominal wall abnormalities. Cases may be termed "pubalgia" if physical examination does not reveal inguinal hernia and there is an absence of other etiology for groin pain. We present nine cases of patients who underwent herniorrhaphies for groin pain. Two patients had groin pain without evidence of a hernia preoperatively (pubalgia). In the remaining seven patients we determined the presence of a hernia by physical examination. At operation, eight patients were found to have inguinal hernias. One patient had no hernia but had partial avulsion of the internal oblique fibers from their insertion at the public tubercle. The average interval from operation to return to full activity was 11 weeks. All patients returned to full activity within 3 months of surgery. One patient had persistent symptoms of mild incisional tenderness, but otherwise there were no recurrences, complications, or persistence of symptoms. Abnormalities of the abdominal wall, including inguinal hernias and microscopic tears or avulsions of the internal oblique muscle, can be an overlooked source of groin pain in the athlete. Operative treatment of this condition with herniorrhaphy can return the athlete to his sport within 3 months.

    Adrenal gland vein sampling is an interventional method to get the blood samples from the adrenal gland vein. The blood is obtained via a catheter which is selectively inserted in the adrenal gland vein. This technique is mainly used to be diagnostic for primary hyperaldosteronism. A full knowledge of the anatomy and variations of the adrenal gland vein, serious preoperative preparation and skilled catheterization manipulation are necessary for obtaining sufficient blood sample and for reducing the occurrence of complications. Providing the physicians with definite diagnostic evidence and being technically feasible, adrenal gland vein sampling should become one of the routine examinations for clarifying the cause of primary hyperaldosteronism.

    Axillary vein access for pacemaker implantation is uncommon in many centres because of the lack of training in this technique. We assessed whether the introduction of the axillary vein technique was safe and efficient as compared with cephalic vein access, in a centre where no operators had any previous experience in axillary vein puncture. Patients undergoing pacemaker implantation were randomized to axillary or cephalic vein access. All three operators had no experience nor training in axillary vein puncture, and self-learned the technique by reading a published review. Axillary vein puncture was fluoroscopy-guided without contrast venography. Cephalic access was performed by dissection of delto-pectoral groove. Venous access success, venous access duration (from skin incision to guidewire or lead in superior vena cava), procedure duration, X-ray exposure, and peri-procedural (1 month) complications were recorded. results We randomized 74 consecutive patients to axillary (n = 37) or cephalic vein access (n = 37). Axillary vein was successfully accessed in 30/37 (81.1%) patients vs. 28/37 (75.7%) of cephalic veins (P = 0.57). Venous access time was shorter in axillary group than in cephalic group [5.7 (4.4-8.3) vs. 12.2 (10.5-14.8) min, P < 0.001], as well as procedure duration [34.8 (30.6-38.4) vs. 42.0 (39.1-46.6) min, P = 0.043]. X-ray exposure and peri-procedural overall complications were comparable in both groups. Axillary puncture was safe and faster than cephalic access even for the five first procedures performed by each operator. Self-taught axillary vein puncture for pacemaker implantation seems immediately safe and faster than cephalic vein access, when performed by electrophysiologists trained to pacemaker implantation but not to axillary vein puncture.

    For meshes to be used effectively for hernia repair, it is imperative that engineers and surgeons standardize the terminology and techniques related to physicomechanical evaluation of these materials. The objectives of this study were to propose standard techniques, perform physicomechanical testing, and classify materials commonly used for inguinal hernia repair. Nine meshes were evaluated: 4 polypropylene, 1 polyester, 1 polytetrafluoroethylene, and 3 partially absorbable. Physical properties were determined through image analysis, laser micrometry, and density measurements. Biomechanical properties were determined through suture retention, tear resistance, uniaxial, and ball burst testing with specimens tested in 2 different orientations. A 1-way ANOVA with Tukey's post-test or a t-test were performed, with p INFINIT (WL Gore & Associates) did not resist tearing as effectively as the others. All meshes exhibited supraphysiologic burst strengths except INFINIT and ULTRAPRO. Significant differences exist between the physicomechanical properties of polypropylene, polyester, polytetrafluoroethylene, and partially absorbable mesh prostheses commonly used for inguinal hernia repair. Orientation of the mesh was also shown to be critical for the success of meshes, particularly those demonstrating anisotropy. Copyright © 2011 American College of Surgeons. Published by Elsevier Inc.

    Two revolutions in inguinal hernia repair surgery have occurred during the last two decades. The first was the introduction of tension-free hernia repair by Liechtenstein in 1989 and the second was the application of laparoscopic surgery to the treatment of inguinal hernia in the early 1990s. The purposes of this study were to assess the safety and effectiveness of laparoscopic totally extraperitoneal (TEP) repair and to discuss the technical changes that we faced on the basis of our accumulative experience. Patients who underwent an elective inguinal hernia repair at the Department of Abdominal Surgery at the Institute of Laparoscopic Surgery (ILS), Bordeaux, between June 1990 and May 2005 were enrolled retrospectively in this study. Patient demographic data, operative and postoperative course, and outpatient follow-up were studied. A total of 3,100 hernia repairs were included in the study. The majority of the hernias were repaired by TEP technique; the repair was done by transabdominal preperitoneal (TAPP) repair in only 3%. Eleven percent of the hernias were recurrences after conventional repair. Mean operative time was 17 min in unilateral hernia and 24 min in bilateral hernia. There were 36 hernias (1.2%) that required conversion: 12 hernias were converted to open anterior Liechtenstein and 24 to laparoscopic TAPP technique. The incidence of intraoperative complications was low. Most of the patients were discharged at the second day of the surgery. The overall postoperative morbidity rate was 2.2%. The incidence of recurrence rate was 0.35%. The recurrence rate for the first 200 repairs was 2.5%, but it decreased to 0.47% for the subsequent 1,254 hernia repairs According to our experience, in the hands of experienced laparoscopic surgeons, laparoscopic hernia repair seems to be the favored approach for most types of inguinal hernias. TEP is preferred over TAPP as the peritoneum is not violated and there are fewer intra-abdominal complications.

    Full Text Available Abstract Introduction A vermiform appendix in an inguinal hernia, inflamed or not, is known as Amyand's hernia. Here we present a case series of four men with Amyand's hernia. Case presentations We retrospectively studied 963 Caucasian patients with inguinal hernia who were admitted to our surgical department over a 12-year period. Four patients presented with Amyand's hernia (0.4%. A 32-year-old Caucasian man had an inflamed vermiform appendix in his hernial sac (acute appendicitis, presenting as an incarcerated right groin hernia, and underwent simultaneous appendectomy and Bassini suture hernia repair. Two patients, Caucasian men aged 36 and 43 years old, had normal appendices in their sacs, which clinically appeared as non-incarcerated right groin hernias. Both underwent a plug-mesh hernia repair without appendectomy. The fourth patient, a 25-year-old Caucasian man with a large but not inflamed appendix in his sac, had a plug-mesh hernia repair with appendectomy. Conclusion A hernia surgeon may encounter unexpected intraoperative findings, such as Amyand's hernia. It is important to be prepared and apply the appropriate treatment.

    Portal vein thrombosis is an important cause of portal hypertension. PVT occurs in association with cirrhosis or as a result of malignant invasion by hepatocellular carcinoma or even in the absence of associated liver disease. With the current research into its genesis, majority now have an underlying prothrombotic state detectable. Endothelial activation and stagnant portal blood flow also contribute to formation of the thrombus. Acute non-cirrhotic PVT, chronic PVT (EHPVO), and portal vein thrombosis in cirrhosis are the three main variants of portal vein thrombosis with varying etiological factors and variability in presentation and management. Procoagulant state should be actively investigated. Anticoagulation is the mainstay of therapy for acute non-cirrhotic PVT, with supporting evidence for its use in cirrhotic population as well. Chronic PVT (EHPVO) on the other hand requires the management of portal hypertension as such and with role for anticoagulation in the setting of underlying prothrombotic state, however data is awaited in those with no underlying prothrombotic states. TIPS and liver transplant may be feasible even in the setting of PVT however proper selection of candidates and type of surgery is warranted. Thrombolysis and thrombectomy have some role. TARE is a new modality for management of HCC with portal vein invasion.

    To assess the suitability of transvaginal duplex ultrasonography to identify pathological reflux in the ovarian and internal iliac veins in women. A retrospective study of patients treated in 2011 and 2012 was performed in a specialised vein clinic. Diagnostic transvaginal duplex ultrasonography in women presenting with symptoms or signs of pelvic vein reflux were compared with the outcomes of treatment from pelvic vein embolisation. A repeat transvaginal duplex ultrasonography was performed 6 weeks later by a blinded observer and any residual reflux was identified. Results from 100 sequential patients were analysed. Mean age 44.2 years (32-69) with mode average parity of 3 (0-5 deliveries). Pre-treatment, 289/400 veins were refluxing (ovarian - 29 right, 81 left; internal iliac - 93 right, 86 left). Coil embolisation was successful in 86/100 patients and failed partially in 14/100 - 5 due to failure to cannulate the target vein. One false-positive diagnosis was made. Currently there is no accepted gold standard for pelvic vein incompetence. Comparing transvaginal duplex ultrasonography with the outcome from selectively treating the veins identified as having pathological reflux with coil embolisation, there were no false-negative diagnoses and only one false-positive. This study suggests that transvaginal duplex ultrasonography could be the gold standard in assessing pelvic vein reflux. © The Author(s) 2014.

    Full Text Available JUSTIFICATIVA E OBJETIVOS: Este estudo avaliou a eficácia da injeção única de bupivacaína a 0,25% no compartimento do psoas ou perivascular inguinal por meio do estimulador de nervos periféricos para analgesia pós-operatória em pacientes submetidos a intervenções cirúrgicas ortopédicas. MÉTODO: Cem pacientes receberam bloqueio do plexo lombar através do compartimento do psoas e foram comparados com 100 pacientes que receberam bloqueio do plexo lombar via perivascular inguinal, identificados pelo estimulador de nervos periféricos com a injeção de 40 mL bupivacaína a 0,25% sem epinefrina. A analgesia nos nervos ilioinguinal, genitofemoral, cutâneo femoral lateral, femoral e obturatório foi avaliada 4, 8, 12, 16, 20 e 24 horas após o final da intervenção cirúrgica. A intensidade da dor foi também avaliada no mesmo período. A quantidade de opióides administrada no pós-operatório foi anotada. Em cinco pacientes de cada grupo, estudo radiográfico com contraste não-iônico foi realizado para avaliar a dispersão da solução anestésica. RESULTADOS: Os nervos ilioinguinal, genitofemoral, cutâneo femoral lateral, femoral e obturatório foram bloqueados em 92% dos pacientes no compartimento do psoas versus 62% no bloqueio perivascular inguinal. O bloqueio do plexo lombar reduziu a necessidade de opióides e 42% dos pacientes submetidos ao bloqueio do compartimento do psoas e 36% dos pacientes no bloqueio inguinal não necessitaram de analgésico adicional no pós-operatório. A duração da analgesia foi em torno de 21 horas com bloqueio do compartimento do psoas e 15 horas com bloqueio perivascular inguinal. CONCLUSÕES: O bloqueio do compartimento do psoas e perivascular inguinal é uma excelente técnica para analgesia pós-operatória em intervenções cirúrgicas ortopédicas reduzindo a necessidade de opióides. Este estudo mostrou que a injeção no compartimento do psoas foi mais fácil e mais efetiva no bloqueio

    Leiomyoma is a rare, smooth muscle tumour that can occur everywhere in the human body. The authors present the history of a 60-year-old female, who had a giant, Mullerian type myxoid leiomyoma in the inguinal region mimicking acute abdominal symptoms. After examination the authors removed the soft tissue mass in the right femoral region reaching down in supine position to the middle third of the leg measuring 335 × 495 × 437 mm in greatest diameters in weight 33 kg. Reconstruction of the tissue defect was performed using oncoplastic guidelines. During the follow-up time no tumour recurrence was detected and the quality of life of the patient improved significantly.

  14. Case report: Varicosity of the communicating vein between the left renal vein and the left ascending lumbar vein mimicking a renal artery aneurysm: Report of an unusual site of varicose veins and a novel hypothesis to explain its association with abdominal pain

    Full Text Available A communicating vein between the left renal vein and the left ascending lumbar vein has only rarely been reported in the imaging literature. There are very few reports of varicosity of this communicating vein. Nonetheless, awareness about this communicating vein is of utmost importance for surgeons performing aortoiliac surgeries and nephrectomies as it may pose technical difficulties during surgery or cause life-threatening retroperitoneal hemorrhage. Varicosity of this venous channel may be mistaken for paraaortic lymphadenopathy, adrenal pseudo-mass, or renal artery aneurysm. We report a case of a patient with varicosity of this communicating vein, which mimicked a left renal artery aneurysm. A novel hypothesis is also proposed to explain the relationship with abdominal pain.

    Objective: To explore the clinical significance of interventional treatment of iliac vein compression syndrome (IVCS). Methods: Percutaneous transluminal angioplasty (PTA) was performed in 40 cases. Thirty-three cases underwent endovascular stent implantation and 27 cases underwent second-stage left saphenous vein ligation and stripping and the valves of left femoral veins narrowing. Thirty-one cases were followed-up postoperatively and the duration was 6-66 months (mean 28 months). Results: The dilation of iliac veins was successful in 36 cases and there were god efficacy in all patients when they discharged from hospital. Followed-up during post-operation, all the limbs ulcers were cured and varicose veins disappeared. The skin pigmentation disappeared in 17 of 19 cases and markedly relieved in 2 cases. Left lower limb swelling disappeared in 15 of 17 cases and relieved in 2 cases. Conclusion: There is good efficacy in the interventional treatment of left iliac vein lesions, but second-stage procedures should be performed in secondary lesions of saphenous veins and valves of femoral veins

    Purpose: To evaluate the influence of elective inguinal node radiation therapy (INRT) on locoregional control (LRC) in patients with early-stage T2N0 anal cancer treated conservatively with primary RT. Methods and Materials: Between 1976 and 2008, 116 patients with T2 node-negative anal cancer were treated curatively with RT alone (n=48) or by combined chemoradiation therapy (CRT) (n=68) incorporating mitomycin C and 5-fluorouracil. Sixty-four percent of the patients (n=74) received elective INRT. Results: Over a median follow-up of 69 months (range, 4-243 months), 97 (84%) and 95 patients (82%) were locally and locoregionally controlled, respectively. Rates for 5-year actuarial local control, LRC, cancer-specific, and overall survival for the entire population were 81.7% ± 3.8%, 79.2% ± 4.1%, 91.1% ± 3.0%, and 72.1% ± 4.5%, respectively. The overall 5-year inguinal relapse-free survival was 92.3% ± 2.9%. Isolated inguinal recurrence occurred in 2 patients (4.7%) treated without INRT, whereas no groin relapse was observed in those treated with INRT. The 5-year LRC rates for patients treated with and without INRT and with RT alone versus combined CRT were 80.1% ± 5.0% versus 77.8% ± 7.0% (P=.967) and 71.0% ± 7.2% versus 85.4% ± 4.5% (P=.147), respectively. A trend toward a higher rate of grade ≥3 acute toxicity was observed in patients treated with INRT (53% vs 31%, P=.076). Conclusions: In cases of node-negative T2 anal cancer, the inguinal relapse rate remains relatively low with or without INRT. The role of INRT in the treatment of early-stage anal carcinoma needs to be investigated in future prospective trials.

    Dynamic ultrasound (US) investigation was performed in 89 patients operated on inguinal hernia with the use of meshes of various type. The US scanning proved to be a highly informative means of visualization, allowing the objective postoperative assessment of muscular and aponeurotic structures as well as the implant form and position. The study showed, that the mesh implantation was always accompanied by the exudative tissue reaction, which was determined by the physico-chemical characteristics of the implant.

    Stenosis of central veins (brachiocephalic vein [BCV] and superior vena cava) occurs in 30% of hemodialysis patients, rarely producing intracranial pathology. The authors present the first cases of BCV stenosis causing perimesencephalic subarachnoid hemorrhage and myoclonic epilepsy. In the first case, a 73-year-old man on hemodialysis presented with headache and blurry vision, and was admitted with presumed idiopathic intracranial hypertension after negative CT studies and confirmatory lumbar puncture. The patient mildly improved until hospital Day 3, when he experienced a seizure; emergency CT scans showed perimesencephalic subarachnoid hemorrhage. Cerebral angiography failed to find any vascular abnormality, but demonstrated venous congestion. A fistulogram found left BCV occlusion with jugular reflux. The occlusion could not be reopened percutaneously and required open fistula ligation. Postoperatively, symptoms resolved and the patient remained intact at 7-month follow-up. In the second case, a 67-year-old woman on hemodialysis presented with right arm weakness and myoclonic jerks. Admission MRI revealed subcortical edema and a possible dural arteriovenous fistula. Cerebral angiography showed venous engorgement, but no vascular malformation. A fistulogram found left BCV stenosis with jugular reflux, which was immediately reversed with angioplasty and stent placement. Postprocedure the patient was seizure free, and her strength improved. Seven months later the patient presented in myoclonic status epilepticus, and a fistulogram revealed stent occlusion. Angioplasty successfully reopened the stent and she returned to baseline; she was seizure free at 4-month follow-up. Central venous stenosis is common with hemodialysis, but rarely presents with neurological findings. Prompt recognition and endovascular intervention can restore normal venous drainage and resolve symptoms.

    The totally extraperitoneal (TEP) approach for surgical repair of inguinal hernias has emerged as a popular technique. We conducted a prospective randomised trial to compare patient comfort scores using different mesh types and fixation using this technique. Over a 14 month period, 146 patients underwent 232 TEP inguinal hernia repairs. We compared the comfort scores of patients who underwent these procedures using different types of mesh and fixation. A non-absorbable 15 × 10 cm anatomical mesh fixed with absorbable tacks (Control group) was compared with either a non-absorbable 15 × 10 cm folding slit mesh with absorbable tacks (Group 2), a partially-absorbable 15 × 10 cm mesh with absorbable tacks (Group 3) or a non-absorbable 15 × 10 cm anatomical mesh fixed with 2 ml fibrin sealant (Group 4). Outcomes were compared at 1, 2, 4 and 12 weeks using the Carolina Comfort Scale (CCS) scores. At 1, 2, 4 and 12 weeks, the median global CCS scores were low for all treatment groups. Statistically significant differences were seen only for median CCS scores and subscores with the use of partially-absorbable mesh with absorbable tacks (Group 3) at weeks 2 and 4. However, these were no longer significant at week 12. In this study, the TEP inguinal hernia repair with minimal fixation results in low CCS scores. There were no statistical differences in CCS scores when comparing types of mesh, configuration of the mesh or fixation methods. Copyright © 2015 IJS Publishing Group Limited.

    The role of a fascia iliaca compartment block (FICB) for postoperative analgesia after total hip arthroplasty (THA) remains questionable. High-dose local anesthetics and a proximal injection site may be essential for successful analgesia. High-dose local anesthetics may pose a risk for local anesthetic systemic toxicity. We hypothesized that a high-dose longitudinal supra-inguinal FICB is safe and decreases postoperative morphine consumption after anterior approach THA. We conducted a prospective, double blind, randomized controlled trial. Patients scheduled for THA were randomized to group FICB (longitudinal supra-inguinal FICB with 40-mL ropivacaine 0.5%) or group C (control, no block). Standard hypothesis tests (t test or Mann-Whitney U test, χ test) were performed to analyze baseline characteristics and outcome parameters. The primary end point of the study was total morphine (mg) consumption at 24 hours postoperatively. Serial total and free ropivacaine serum levels were determined in 10 patients. After obtaining ethical committee approval and written informed consent, 88 patients were included. Mean (SD) morphine consumption at 24 hours postoperatively was reduced in group FICB compared to group C: 10.25 (1.64) mg versus 19.0 (2.4) mg (P = 0.004). Using a mean dose of 2.6-mg/kg ropivacaine (range, 2-3.4 mg/kg), none of the patients had total or free ropivacaine levels above the maximum tolerated serum concentration. We conclude that a high-dose longitudinal supra-inguinal FICB reduces postoperative morphine requirements after anterior approach THA.Clinical Trials Registry: EU Clinical Trials Register. www.clinicaltrialsregister.eu #2014-002122-12.

    Objective: To evaluate the angiographic feature of hepatic vein obstruction. Methods Forty-five patients (male 23, female 22, age 9-54 years) suffered from hepatic vein obstruction. The inferior vena cavography and the hepatic venography were performed in all cases. Results: IVC was free in 37 patients with hepatic vein obstruction, both IVC and HV were obstructed in 8 patients. The local or long stenosis of IVC was found in 31 inferior vena cavography. The diameter of IVC was normal in 12 patients. The sign of membranous dome was found in hepatic vein orifice in 5 cases and in accessory hepatic vein orifice in 4 cases. Intrahepatic venous collaterals were found in 45 cases. Conclusion: Hepatic vein obstruction can be reproached primarily in inferior vena cavography, the membranous dome is a direct sign of membranous obstruction of HV and AHV in inferior vena cavography. The selected hepatic venography can provide reliable evidence to diagnose hepatic vein obstruction

    To review our experience and outcomes after inguinal hernia repair using the lightweight self-adhering sutureless mesh "Adhesix™" and demonstrate the safety and efficacy of this mesh. This is a 3-year retrospective study that included 143 consecutive patients who underwent 149 inguinal hernia repairs at our department of surgery. All hernias were repaired using a modified Lichtenstein technique. Preoperative, perioperative, and postoperative data were prospectively collected. Incidence of chronic pain, postoperative complications, recurrence, and patient satisfaction were assessed three years postoperatively by conducting a telephone survey. We had 143 patients with a mean age of 58 years (17-84), who underwent 149 hernia repairs using the Adhesix™ mesh. Ninety-two per cent (131 patients) were males. Only 10 patients (7%) had a postoperative pain for more than three years. In our series, neither age nor gender was predictive of postoperative pain. Only one patient had a hematoma lasting for more than one month and only four patients (2.8%) had a recurrence of their hernia within three years of their initial surgery. Ninety per cent of the patient expressed their satisfaction when surveyed three years after their surgery. In conclusion, the use of the self-adhering sutureless mesh for inguinal hernia repair has been proving itself as effective as the traditional mesh. Adhesix™ is associated with low chronic pain rate, recurrence rate, and postoperative complications rate, and can be safely adopted as the sole technique for inguinal hernia repair.

    We present a case of external iliac vein patch venoplasty to accommodate rescue vascular access via a polytetrafluoroethylene loop arteriovenous fistula graft (AVG) for a patient with multiple central venous stenoses. A 35-year-old female with anti-glomerular basement membrane antibody disease required rescue vascular access for hemodialysis. Repeated occlusion and/or thrombosis of long-term central venous access cannulae, to facilitate dialysis, had caused stenosis of brachiocephalic veins: right external iliac vein and occlusion of the left common iliac vein. A previous right brachiobasilic fistula had occluded within 1 year. No other upper limb options for arteriovenous fistula (AVF) were available. A right external iliac vein bovine patch angioplasty concurrently with a polytetrafluoroethylene AV graft between common femoral artery and common femoral vein was performed to restore venous patency and allow rescue dialysis access. At 3-year follow-up, the fistula remains widely patent with 2 L/min flow rates and no recurrent stenosis to the treated iliac vein. She has not required any further surgical or interventional radiological procedures to maintain fistula or central venous patency. Central venous stenosis or occlusion is common for patients requiring dialysis, especially those with multiple previous long-term central venous cannulations. If restriction of outflow is present, AVF may fail. Venous patch angioplasty in these cases is a successful technique, allowing AVF formation and long-term patency. Central venous stenosis can be treated successfully with patch venoplasty to accommodate AVF/AVG formation for rescue vascular access; this is a potentially lifesaving intervention for patients requiring dialysis.

    Full Text Available There is increasing demand world-wide, from government agencies and the private sector for cutting-edge biometric security technology that is difficult to breach but userfriendly at the same time. Some of the older tools, such as fingerprint, retina and iris scanning, and facial recognition software have all been found to have flaws and often viewed negatively because of many cultural and hygienic issues associated with them. Comparatively, mapping veins as a human barcode, a new technology, has many advantages over older technologies. Specifically, reproducing a three-dimensional model of a human vein system is impossible to replicate. Vein map technology is distinctive because of its state-of-the-art sensors are only able to recognize vein patterns if hemoglobin is actively flowing through the person

    To see if pre-partum factors have a relationship to the development of inguinal hernia in children. A prospective study on children with hernia. On first contact, the affected child was examined and data like the age, sex, weight, blood group, the diagnosis, side of the lesion and other co-morbid conditions was recorded. The mother filled a questionnaire about her age, parity, illness during pregnancy, her mode of delivery and the patient's position in the family. There were 104 patients from 103 mothers, their ages ranged from 13 days to 14 years with the highest incidence in the 1-4 age group. The sex ratio was overwhelmingly male (M:F ratio was 38:1). Right sided hernias were predominant. Only 7% had a family history. The peak age group of the mothers was 26-32 years and about 33% of the mothers had some illness during pregnancy. The birth positions of the patients showed that majority of them were either 1st or 2nd born children. Women of ages 26-32 likelyto have children with inguinal hernia. Malaria during pregnancy is unlikely to have a role to play. 1st and 2nd born male children have a higher chance of having inguinal hernia.

    A laparoscopic approach for inguinal hernia repair is now considered the gold standard. Laparoscopic surgery is associated with a significant reduction in postoperative pain. Epidural analgesia cannot be used in patients with perioperative anticoagulant therapy because of complications such as epidural hematoma. As such, regional anesthetic techniques, such as ultrasound-guided rectus sheath block and transversus abdominis plane block, have become increasingly popular. However, even these anesthetic techniques have potential complications, such as rectus sheath hematoma, if vessels are damaged. We report the use of a transperitoneal laparoscopic approach for rectus sheath block and transversus abdominis plane block as a novel anesthetic procedure. An 81-year-old woman with direct inguinal hernia underwent laparoscopic transabdominal preperitoneal inguinal repair. Epidural anesthesia was not performed because anticoagulant therapy was administered. A Peti-needle™ was delivered through the port, and levobupivacaine was injected though the peritoneum. Surgery was performed successfully, and the anesthetic technique did not affect completion of the operative procedure. The patient was discharged without any complications. This technique was feasible, and the procedure was performed safely. Our novel analgesia technique has potential use as a standard postoperative regimen in various laparoscopic surgeries. Additional prospective studies to compare it with other techniques are required. © 2017 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and John Wiley & Sons Australia, Ltd.

    Ascending contrast venography is the definitive standard method for the diagnosis of deep vein thrombosis (DVT) of the lower extremities. Authors analysed 22 cases of DVT clinically and radiographically. 1.The patients ranged in age from 15 to 70 yrs and the most prevalent age group was 7th decade (31%).

    Meandering pulmonary veins is a rare clinical entity that can be mistaken for more complex congenital syndromes such as hypogenetic lung syndrome. We report imaging findings in a rare incidentally detected case of bilateral meandering pulmonary veins. We briefly discuss the role of imaging in diagnosing this condition, with particular emphasis on contrast-enhanced CT. (orig.)

  12. Glow discharge, its sensitivity to infra-red radiation. Observations made during the testing of multiwire proportional chambers

    It has been shown that under glow discharge conditions, multiwire proportional chambers are sensitive to infra-red radiation. Discharge current measurements and light change measurements have been made and the effect of the input window on the output signal and the importance of the finish of the anode and HT wires have been investigated. From these observations it would appear that a glow discharge in the form detailed in this report is sensitive to infra-red radiation though work is still required to optimise the parameters of such a device for IR detection or solar cell technology.

  13. The veining phenomenon in unalloyed plutonium

    International Nuclear Information System (INIS)

    White, J.S.

    1976-01-01

    An investigation has been made of the veining phenomenon in unalloyed plutonium. The surface markings, or veins, which are sometimes seen on α-phase plutonium samples, arise as a result of the β→α transformation. As far as is known, this veining is unrivalled in its scale and form as compared with the solid state surface transformation effects shown by any other metal. The phenomenon has been explained by the application of the Le Chatelier principle to the phase change. In this instance, the large (10%) volume contraction associated with the β→α reaction and the anisotropy of the nonoclinic α-phase structure, account for the fact that the veins are so prominent in plutonium. On the basis of the proposed model, the veins can only form at temperatures where the transformation mechanism is non-martensitic. (Auth.)

    Full Text Available A 32-years old woman presented to the emergency room of Bozok University Research Hospital with right renal colic. Multidetector computed tomography (MDCT showed compression of the proximal ureter by the right ovarian vein and compression of the right distal ureter by the right external iliac vein. To the best of our knowledge, right proximal ureteral compression by the ovarian vein together with distal ureteral compression by the external iliac vein have not been reported in the literature. Ovarian vein and external iliac vein compression should be considered in patients presenting to the emergency room with renal colic or low back pain and a dilated collecting system.

    We aimed to explore the feasibility and the safety of the laparoscopic surgery for incarcerated indirect inguinal hernia (IIH) in children. From January 2012 to December 2014, 64 children were enrolled into this study. All 64 patients received laparoscopic surgery and we reviewed their perioperative and postoperative follow-up studies. In addition, we enrolled 60 cases of children who received traditional surgery of IIH administered through minimally invasive surgery as the control group. Results from the present study showed that the mean operation time for the laparoscopic group was 41.5 min (range, 15-80 min) which was significantly shorter than the control group. Nine cases developed incarcerated intestine necrosis, expanded umbilical incision and parallel resection anastomosis. They received laparoscopic hernia sac high ligation. Only 5 cases developed scrotum edema after the surgery. The postoperative length of the stay ranged from 2 to 7 days (average, 3.2). The postoperative follow-up was from 6 months to 1 year and no relapse or secondary testicular atrophy was observed in the laparoscopic group. The operation time, incidence of postoperative complications and length of stay in the laparoscopic group were decreased compared to the control group, and differences were statistically significant (Pincarcerated inguinal hernia is safe and feasible and produced better results compared with the alternative.

  17. Investigation of adverse events associated with an off-label use of arterial stents and CE-marked iliac vein stents in the iliac vein: insights into developing a better iliac vein stent.

    2018-06-01

    We analyzed the adverse events associated with an off-label use of arterial stents and CE-marked iliac vein stents for the treatment of iliac venous thromboembolism and investigated their relationships with the anatomical features of the iliac vein, to gain insights into the development of a better iliac vein stent. Reports of adverse events following the use of stents in the iliac vein were retrieved from the Manufacturer and User Facility Device Experience (MAUDE) database that contain suspected device-associated complications reported to the Food and Drug Administration. Data from 2006 to 2016 were investigated. The literature analysis was also conducted using PubMed, Cochrane Library, EMBASE, and Web of Science focusing on English articles published up to 4 October 2016. The analysis of 88 adverse events from the MAUDE database and 182 articles from the literature revealed that a higher number of adverse events had been reported following the use of arterial stents in the iliac vein compared to CE-marked iliac vein stents. While stent migration and shortening were reported only for the arterial stents, stent fracture and compression occurred regardless of the stent type, even though a vein does not pulsate. A study of the anatomical features of the iliac vein implies that bending, compression, and kink loads are applied to the iliac vein stents in vivo. For designing, developing, and pre-clinical testing of stents intended for use in the iliac vein, the above mechanical load environments induced by the anatomical features should be considered.

    Devarajan, Karthik; Rogers, Loni; Smith, Paul; Schwaitzberg, Steven D

    2012-09-01

    The Affordable Care Act has stimulated discussion to find feasible, alternate payment models. Adopting a global payment (GP) mechanism may dampen the high number of procedures incentivized by the fee-for-service (FFS) system. The evolving payment mechanism should reflect collaboration between surgeon and system goals. Our aim was to model and perform simulation of a GP system for hernia care and its impact on cost, revenue, and physician reimbursement in an integrated health care system. The results of the 2006 Watchful Waiting (WW) vs Repair of Inguinal Hernia in Minimally Symptomatic Men trial was used as a clinical model for the natural history and progression of inguinal hernia disease Simulations were built using 2009 financial and clinical data from the Cambridge Health Alliance to model costs and revenues in managing care for a 4-year cohort of inguinal hernia patients; FFS, FFS-WW, and the GP-WW were modeled. To build this GP model, surgeons were paid a constant $500 per patient whether herniorrhaphy was performed or not. Compared with the actual combined physician and hospital revenue under the current FFS model ($308,820), implementing the FFS-WW system for 4 years for 139 hernia patients decreased hospital and physician revenues by $93,846 and $19,308, respectively. This resulted in a total savings of $113,154 for the payors only. In contrast, when using WW methodology within a GP model, system savings of $69,174 were observed after 4 years, with preservation of physician and hospital income. Collaboration to achieve shared savings can be accomplished by pooling physician and hospital revenue in order to meet the goals of all parties. Copyright © 2012 American College of Surgeons.

    We encountered a patient with gastric varix draining not via the usual left suprarenal vein but via the left inferior phrenic vein joining the left hepatic vein. Transfemoral balloon-occluded retrograde transvenous obliteration (BRTO) of the varix was performed under balloon occlusion of the left inferior phrenic vein via the left hepatic vein and retrograde injection of the sclerosing agent (5% of ethanolamine oleate) into the gastric varix. Disappearance of the gastric varix was confirmed on endoscopic examination 2 months later.

  3. Spectral relationships for atmospheric correction. I. Validation of red and near infra-red marine reflectance relationships.

    Goyens, C; Jamet, C; Ruddick, K G

    2013-09-09

    The present study provides an extensive overview of red and near infra-red (NIR) spectral relationships found in the literature and used to constrain red or NIR-modeling schemes in current atmospheric correction (AC) algorithms with the aim to improve water-leaving reflectance retrievals, ρw(λ), in turbid waters. However, most of these spectral relationships have been developed with restricted datasets and, subsequently, may not be globally valid, explaining the need of an accurate validation exercise. Spectral relationships are validated here with turbid in situ data for ρw(λ). Functions estimating ρw(λ) in the red were only valid for moderately turbid waters (ρw(λNIR) turbidity ranges presented in the in situ dataset. In the NIR region of the spectrum, the constant NIR reflectance ratio suggested by Ruddick et al. (2006) (Limnol. Oceanogr. 51, 1167-1179), was valid for moderately to very turbid waters (ρw(λNIR) turbid waters (ρw(λNIR) > 10(-2)). The results of this study suggest to use the red bounding equations and the polynomial NIR function to constrain red or NIR-modeling schemes in AC processes with the aim to improve ρw(λ) retrievals where current AC algorithms fail.

  4. Vein Patch Closure Using Below the Knee Greater Saphenous Vein for Femoral Endarterectomy Procedures is Not Always a Safe Choice

    M. Berner

    Full Text Available : Background: The complication of vein patch rupture is well described after carotid patch angioplasty; however, there is a paucity of data about the safety of vein patch closure in the setting of femoral endarterectomy. Methods/results: From May 2012 to May 2015, 115 femoral endarterectomies with patch closure were performed. A patch rupture occurred in three cases (2.6% with a mortality rate of 66% (2/3. In all cases the greater saphenous vein below the knee was used as patch material. Discussion/conclusion: Vein patches, particularly from small calibre veins, should be excluded in femoral endarterectomy procedures as they pose a substantial risk of rupture.

    2012-01-01

    Varicose veins affect approximately one-third of the adult population and result in significant psychological, physical, and financial burden. Nevertheless, the molecular pathogenesis of varicose vein formation remains unidentified. Venous hypertension exerted on veins of the lower extremity is considered the principal factor in varicose vein formation. The role of mechanotransduction of the high venous pressure in the pathogenesis of varicose vein formation has not been adequately investigated despite a good progress in understanding the mechanomolecular mechanisms involved in transduction of high blood pressure in the arterial wall. Understanding the nature of the mechanical forces, the mechanosensors and mechanotransducers in the vein wall, and the downstream signaling pathways will provide new molecular targets for the prevention and treatment of varicose veins. This paper summarized the current understanding of mechano-molecular pathways involved in transduction of hemodynamic forces induced by blood pressure and tries to relate this information to setting of venous hypertension in varicose veins.

    The Schwinger-Dyson equations for the ghost propagator and the ghost-ghost-gluon vertex function are studied in the Landau gauge. A confining infra-red singularity is assumed for the gluon propagator and a suitable approximation is devised for the solution of the integral equations. It is found that the bare values of the ghost propagator and coupling cannot be a consistent solution of either equation. It is determined a possible behaviour of the correction factor for the ghost propagator in the small-momentum limit and discussed the consistency of the approximation schemes for the gluon propagator that neglet Faddeev-Popov ghost

    The international guidelines recommend sentinel lymph node biopsy (SLNB) for lymph node staging in penile cancer with non-palpable inguinal lymph nodes (LN) but it is not recommended with palpable inguinal LN. The aim of this study was to evaluate the reliability and morbidity of SLNB in combination with an ultrasound-guided resection of suspect inguinal LNs as a new multimodal, minimally invasive staging approach in these patients. We performed SLNB in 26 penile cancer patients with 42 palpable inguinal LNs. Prior to the combined staging procedures the patients underwent an ultrasound examination of the groins as well as planar lymphatic drainage scintigraphy and SPECT/CT scans. During the surgical procedure, the radioactive-labelled sentinel lymph nodes and, in addition, sonographically suspect LNs, were resected under ultrasound guidance. Follow-up screening was done by ultrasound examination of the groins according to the guidelines of the European Association of Urology. Nineteen groins of 42 preoperatively palpable inguinal findings were histologically tumor-positive. SLNB alone showed lymphogenic metastases in 14 groins. Sonography revealed five further metastatic groins, which would not have been detected during SLNB due to a tumor-related blockage of lymphatic drainage or a so-called re-routing of the tracer. During follow-up, none of the 28 groins with tumor-negative LN status showed any LN recurrence in this combined investigation technique. The median follow-up period was 46 (24 to 92) months. Morbidity of this procedure was low at 4.76 % in relation to the number of groins resp. 7.69 % in relation to the number of patients. The results show that this combined procedure is a reliable multimodal diagnostic approach for treatment of penile cancer patients with palpable inguinal LNs. It is associated with low morbidity rates. SLNB alone would lead to a significantly higher false-negative rate in these patients. The encouraging results of this work can

    Background: despite the proven effectiveness of preventive therapy for deep vein thrombosis, a significant proportion of patients at risk for thromboembolism do not receive prophylaxis during hospitalization. Our objective was to determine the adherence to thrombosis prophylaxis guidelines in a general hospital as a quality control strategy. Methods: a random audit of clinical charts was conducted at the Tijuana General Hospital, Baja California, Mexico, to determine the degree of adherence to deep vein thrombosis prophylaxis guidelines. The instrument used was the Caprini's checklist for thrombosis risk assessment in adult patients. Results: the sample included 300 patient charts; 182 (60.7 %) were surgical patients and 118 were medical patients. Forty six patients (15.3 %) received deep vein thrombosis pharmacologic prophylaxis; 27.1 % of medical patients received deep vein thrombosis prophylaxis versus 8.3 % of surgical patients (p < 0.0001). Conclusions: our results show that adherence to DVT prophylaxis at our hospital is extremely low. Only 15.3 % of our patients at risk received treatment, and even patients with very high risk received treatment in less than 25 % of the cases. We have implemented strategies to increase compliance with clinical guidelines.

    2018-02-01

    Full Text Available Adrenal vein development in utero occurs concurrently with the development of the inferior vena cava, the renal veins, and the gonadal veins. The embryologic formation of these veins involves communication of various venous systems. Although the left adrenal-renal vein complex is most commonly described as a shared emptying of the left adrenal vein and the left inferior phrenic vein into the left renal vein, there have been reports of numerous anatomic variations of this complex. In this report, we present a case of a rare variant of the left adrenal vein, in which the left adrenal vein empties into the left gonadal vein, which takes an atypical course superolateral to the left kidney.

  12. On dynamics of uranium vein mineralization

    1981-01-01

    The formation of urnaium vein deposits and the essence of consanguinity of the mineralization and wall metasomatites are considered. The formation of uranium mineralization is analysed from the positions of Korzhinsky D. S. : the formation of metasomatite aureole and associated vein ores take place as a result of the development of one solution flow while the formation of mineral vein associations occurs on the background of contineous filtration of the solution during metasomato is due to a repeated (pulse) half-opening of fractures and their filling with a part of filtrating solution. The analysis of the available information on the example of two different uranium manifestations permits to reveal certain relations both in the character of wall rock alterations and between the metasomatosis and the formation of ore minerals in veins. The conclusion is made that spatial-time correlations of vein formations with wall metasomatites attest that the pulse formation of ores in veinlets occurs on the background and in interrelation with a consecutive precipitation of components in the aureole volume. The analysis of element migration dynamics in wall aureole carried out from the positions of the Korzhinsky hypothesis of the advance wave of acid components that takes into account the interaction of continuous and pulse mechanisms of solution movement permits to avoid contradictions when interpreting the processes of wall rock alterations and vein ore-forming, and permits to make a common scheme of vein ore-genesis [ru

    Full Text Available Sertoli cell tumors (SCTs are rare tumors accounting for <1% of all testicular tumors. Here, we report a rare case of SCT in a 60-year-old man presenting as a painless swelling in the right groin since childhood. Clinically, he presented with right-sided inguinal hernia with absence of the right testis. He had normal left testis and had no gynecomastia or infertility. The specimen of hernial sac showed testis with a 1.6 cm × 1.5 cm nodular mass having gray tan-cut surface. Histopathologically, the testis showed atrophy and the nodular portion showed tumor cells arranged in tubular and microcystic pattern, with no solid pattern or necrosis. The diagnosis of SCT was confirmed with immunohistochemical staining for inhibin which showed fine granular cytoplasmic positivity. Cryptorchid testis having SCT and presenting as a content of inguinal hernia is a rare occurrence.

    Lehotska, V.; Dostalova, K.; Durkovsky, A.; Samal, V.

    1995-01-01

    In this contribution, the authors give an account of a rare case of a cavernous transformation of the portal vein that may have originated secondarily in a proliferative hematogenous disease with a polyglobulia and thrombosis in the periferal blood count as well as development of portal hypertension of a prehepatal type. The state of hyper-coagulation in a myeloproliferative disease may have lead to a chronic thrombosis of the portal vein with a subsequent malformation of the portal vein in terms of a cavernous transformation of the portal vein. The case is an interesting one because of the discrepancy between the gravity of the thrombotic complication and slightness of the symptoms in the clinical picture. The authors point out the importance of ultrasonography and computed tomography examination following the intravenous application of a water solution of a contrast medium in a morphologic diagnosing of a rare complication of a chronic thrombotic clot of the portal vein - the cavernous transformation.

    2015-01-01

    Introduction In up to 0.07% of the general population, the right anterior cardinal vein obliterates and the left remains open, creating an absent right superior caval vein and a persistent left superior caval vein.

    Finger vein authentication is a personal identification technology using finger vein images acquired by infrared imaging. It is one of the newest technologies in biometrics. Its main advantage over other biometrics is the low risk of forgery or theft, due to the fact that finger veins are not normally visible to others. Extracting finger vein patterns from infrared images is the most difficult part in finger vein authentication. Uneven illumination, varying tissues and bones, and changes in the physical conditions and the blood flow make the thickness and brightness of the same vein different in each acquisition. Accordingly, extracting finger veins at their accurate positions regardless of their thickness and brightness is necessary for accurate personal identification. For this purpose, we propose a new finger vein extraction method which is composed of gradient normalization, principal curvature calculation, and binarization. As local brightness variation has little effect on the curvature and as gradient normalization makes the curvature fairly uniform at vein pixels, our method effectively extracts finger vein patterns regardless of the vein thickness or brightness. In our experiment, the proposed method showed notable improvement as compared with the existing methods.

    The aim of this study is to evaluate anesthesia and recovery profile in pediatric patients after inguinal hernia repair with caudal block or local wound infiltration. In this prospective interventional clinical study, the anesthesia and recovery profile was assessed in sixty pediatric patients undergoing inguinal hernia repair. Enrolled children were randomly assigned to either Group Caudal or Group Local infiltration. For caudal blocks, Caudal Group received 1 ml/kg of 0.25% bupivacaine; Local Infiltration Group received 0.2 ml/kg 0.25% bupivacaine. Investigator who was blinded to group allocation provided postoperative care and assessments. Postoperative pain was assessed. Motor functions and sedation were assessed as well. The two groups did not differ in terms of patient characteristic data and surgical profiles and there weren't any hemodynamic changes between groups. Regarding the difference between groups for analgesic requirement there were two major points - on one hand it was statistically significant p < 0.05 whereas on the other hand time to first analgesic administration was not statistically significant p = 0.40. There were significant differences in the incidence of adverse effects in caudal and local group including: vomiting, delirium and urinary retention. Between children undergoing inguinal hernia repair, local wound infiltration insures safety and satisfactory analgesia for surgery. Compared to caudal block it is not overwhelming. Caudal block provides longer analgesia, however complications are rather common.

    To evaluate the safety and efficacy of retrograde endovenous laser ablation (EVLA) and to compare it with the conventional antegrade EVLA for incompetent small saphenous vein (SSV). Small saphenous vein was cannulated via two approaches under ultrasound-guidance. One method involved puncturing the SSV cranially at mid-calf (the antegrade group). If the antegrade puncture into the SSV failed twice, the other approach for puncture was selected that involved puncturing the SSV toward the ankle (the retrograde group). Patients were evaluated in terms of technical and clinical success, closure rates of the SSV, and complications including pain, bruising, or paresthesia at all follow-up visits. The 1470 nm endovenous laser was used in all limbs. Technical success was seen in all limbs in both groups (100%). Closure rate in both groups showed about 95%, without significant difference (p = 0.685). Similar linear endovenous energy density was supplied during the EVLA in both groups (p = 0.876). Three frequent complications including bruising, pain, and paresthesia did not show statistical significance between groups (p = 0.465, 0.823, 1.000, respectively). Major complications were absent in both groups. The EVLA for the incompetent SSV using a retrograde approach is safe and effective and should be considered the alternative method if the antegrade access fails due to vasospasm or small SSV diameter.

    Full Text Available Endometriosis is a condition which affects women during their reproductive age. We present the case of a 42 years old Caucasian nulliparous woman accusing in the last three months a painful bulging mass in the right groin. The patient reported that the mass increases in size during prolonged standing and lifting of heavyweights. In addition, the inguinal pain was exacerbated during ovulation. The patient underwent surgery, during which wide excision of the nodule was performed. Furthermore, both direct and indirect hernia sacs were found and dissected, the content was reduced and the sacs were excised. Four months after the surgery, the patient was free of symptoms and had no signs of recurrence.

    To determine the feasibility of transcaval transjugular intrahepatic portosystemic shunt (TIPS) in patients with occluded previous TIPS. Between February 1996 and December 2000 we performed five transcaval TIPS procedures in four patients with recurrent gastric cardiac variceal bleeding. All four had occluded TIPS, which was between the hepatic and portal vein. The interval between initial TIPS placement and revisional procedures with transcaval TIPS varied between three and 31 months; one patient underwent transcaval TIPS twice, with a 31-month interval. After revision of the occluded shunt failed, direct cavoportal puncture at the retrohepatic segment of the IVC was attempted. Transcaval TIPS placement was technically successful in all cases. In three, tractography revealed slight leakage of contrast materials into hepatic subcapsular or subdiaphragmatic pericaval space. There was no evidence of propagation of extravasated contrast materials through the retroperitoneal space or spillage into the peritoneal space. After the tract was dilated by a bare stent, no patient experienced trans-stent bleeding and no serious procedure-related complications occurred. After successful shunt creation, variceal bleeding ceased in all patients. Transcaval TIPS placement is an effective and safe alternative treatment in patients with occluded previous TIPS and no hepatic veins suitable for new TIPS.

    A novel 3D reconstruction and fast imaging system for subcutaneous veins by augmented reality is presented. The study was performed to reduce the failure rate and time required in intravenous injection by providing augmented vein structures that back-project superimposed veins on the skin surface of the hand. Images of the subcutaneous vein are captured by two industrial cameras with extra reflective near-infrared lights. The veins are then segmented by a multiple-feature clustering method. Vein structures captured by the two cameras are matched and reconstructed based on the epipolar constraint and homographic property. The skin surface is reconstructed by active structured light with spatial encoding values and fusion displayed with the reconstructed vein. The vein and skin surface are both reconstructed in the 3D space. Results show that the structures can be precisely back-projected to the back of the hand for further augmented display and visualization. The overall system performance is evaluated in terms of vein segmentation, accuracy of vein matching, feature points distance error, duration times, accuracy of skin reconstruction, and augmented display. All experiments are validated with sets of real vein data. The imaging and augmented system produces good imaging and augmented reality results with high speed.

    Biometric identification is an emerging technology that can solve security problems in our networked society. A reliable and robust personal verification approach using dorsal hand vein patterns is proposed in this paper. The characteristic of the approach needs less computational and memory requirements and has a higher recognition accuracy. In our work, the near-infrared charge-coupled device (CCD) camera is adopted as an input device for capturing dorsal hand vein images, it has the advantages of the low-cost and noncontact imaging. In the proposed approach, two finger-peaks are automatically selected as the datum points to define the region of interest (ROI) in the dorsal hand vein images. The modified two-directional two-dimensional principal component analysis, which performs an alternate two-dimensional PCA (2DPCA) in the column direction of images in the 2DPCA subspace, is proposed to exploit the correlation of vein features inside the ROI between images. The major advantage of the proposed method is that it requires fewer coefficients for efficient dorsal hand vein image representation and recognition. The experimental results on our large dorsal hand vein database show that the presented schema achieves promising performance (false reject rate: 0.97% and false acceptance rate: 0.05%) and is feasible for dorsal hand vein recognition.

    Ovarian vein thrombosis is a rare postpartum complication (0.1%). It can be fatal, since it can lead to sepsis, pulmonary thromboembolisms and inferior vena cava or renal vein thrombosis. Computed tomography and magnetic resonance imaging are the techniques of choice for its diagnosis, while the value of ultrasound is limited due to its low sensitivity and specificity. We report the case of a woman who, during puerperium, developed thrombosis of right ovarian vein that presented clinical, ultrasonographic and computed tomographic features of appendicitis. We describe the radiological sings and stress the fact that this diagnosis should be suspected in puerperal women. (Author) 9 refs

    Laparoscopic total extraperitoneal (TEP) inguinal hernia repair is an effective and safe method for the treatment of inguinal hernia. There are very few studies on regional anesthesia methods in TEP surgery. To compare TEP inguinal hernia repair performed when the patient was treated under spinal anesthesia (SA) with that performed under general anesthesia (GA). All total of 80 patients were studied between December 2015 and March 2017. Hyperbaric bupivacaine and fentanyl were used for SA, to achieve a sensorial level of T3. Propofol, sevoflurane, rocuronium, fentanyl, and tracheal intubation were used for GA. Intraoperative events related to SA, surgical times, intra- and postoperative complications, and pain scores were recorded. The mean operative time in the SA TEP group was 70.2 ±6.7 min, which was significantly longer than the mean operative time in the GA TEP group of 67.2 ±6.2 min (p < 0.038). The mean pain scores in the SA TEP group were 0.23 ±0.42 at the first hour, 1.83 ±0.64 at 6 h and 1.28 ±0.45 at 24 h. These scores were significantly lower than the corresponding scores of 5.18 ±0.84 (p < 0.001), 2.50 ±0.55 (p < 0.001) and 1.58 ±0.55 in the GA TEP group. Generally, patients were more satisfied with SA than GA (p < 0.004). Spinal anesthesia TEP is significantly less painful in the early postoperative period, leading to earlier ambulation than GA TEP. Additionally, SA TEP results in significantly less need for analgesics and better patient satisfaction results. SA TEP seems to be a better alternative than the existing GA TEP.

It commonly affects the deep leg veins (such as the calf veins, femoral vein, or popliteal vein or the deep veins of the pelvis. It is a potentially dangerous condition that can lead to preventable morbidity and mortality.Aim: To present an update on the causes and management of DVT.Methods: A review of publications obtained from Medline search, medical libraries, and Google.Results: DVT affects 0.1% of persons per year. It is predominantly a disease of the elderly and has a slight male preponderance. The approach to making a diagnosis currently involves an algorithm combining pretest probability, D-dimer testing, and compression ultrasonography. This will guide further investigations if necessary. Prophylaxis is both mechanical and pharmacological. The goals of treatment are to prevent extension of thrombi, pulmonary embolism, recurrence of thrombi, and the development of complications such as pulmonary hypertension and post-thrombotic syndrome.Conclusion: DVT is a potentially dangerous condition with a myriad of risk factors. Prophylaxis is very important and can be mechanical and pharmacological. The mainstay of treatment is anticoagulant therapy. Low-molecular-weight heparin, unfractionated heparin, and vitamin K antagonists have been the treatment of choice. Currently anticoagulants specifically targeting components of the common pathway have been recommended for prophylaxis. These include fondaparinux, a selective indirect factor Xa inhibitor and the new oral selective direct thrombin inhibitors (dabigatran and selective

    To investigate which factors other than history of superficial vein thrombosis (SVT) are associated with recurrent spontaneous SVT episodes in patients with varicose veins (VVs). Patients with a history of spontaneous SVT and VVs were followed up for a mean period of 55 months. Demographics, comorbidities, and thrombophilia screening test were analyzed. Patients were grouped according to the clinical-etiology-anatomy-pathophysiology classification. A multiple logistic regression analysis with the forward likelihood ratio method was undertaken. Thirteen patients out of 97 had a recurrence SVT episode during the follow-up period. All those patients were identified to have a thrombophilia defect. Protein C and S, antithrombin, and plasminogen deficiencies were more frequently present in patients without recurrence. Gene mutations were present in 38% in the nonrecurrence group and 77% in the recurrence group. After logistic regression analysis, patients with dislipidemia and mutation in prothrombin G20210A (FII) had an increased risk for recurrence by 5.4-fold and 4.6-fold, respectively. No deep vein thrombosis or pulmonary embolism occurred. Dislipidemia and gene mutations of F II are associated with SVT recurrence in patients with VVs. A selection of patients may benefit from anticoagulation in the short term and from VVs intervention in the long term. © The Author(s) 2015.

    2D time-of-flight MR venography (2D TOF MRV) was performed in 16 patients (25 calves) with varicose veins and 2 volunteers (4 calves), and compared with venography. Sequential SPGR (TR/TE/FA=45 ms/7 ms/60deg) transverse images and/or GRASS (TR/TE/FA=100 ms/13 ms/60deg) transverse images were obtained for MRV. Superior presaturation pulse (S-SAT) was placed in 21 calves, and 0.05 mmol/kg Gd-DTPA was used in all calves. Projection MRVs were generated with maximum intensity projection (MIP) reconstruction. Regarding sequence parameter, S-SAT was useful to eliminate signal from artery that would obscure the signal of deep veins. The detectability of deep veins was improved with the use of S-SAT. In the comparison with venography, MRV could more clearly demonstrate varicose veins more than 5 mm in diameter and their drainage veins than venography. But it could not so clearly demonstrate deep veins as venography. It could not detect fine varicose veins less than 5 mm in diameter and connecting veins with valve insufficiency. In the examination of varicose veins, detection of deep veins, large varicose veins and their main drainage veins is clinically important, because diagnosis of patency of deep veins and dilatation of the drainage veins is necessary to choose the treatment, concluding conservative therapy, stripping and sclerotherapy. However, detection of fine varicose veins and connecting veins are not so important because those veins seldom need treatment. MRV was not so suitable for detection of deep veins, but very useful for detection of varicose veins more than 5 mm in diameter and their main drainage veins. In conclusion, MRV is non-invasive and effective method in varicose veins of calf, and it can take the place of venography with the improvement of deep vein detectability. (author)

    Full Text Available Background/purpose: Thickening of the spermatic cord is a clinical sign of an inguinal hernia. We therefore tested whether pre-operative spermatic cord ultrasonography could reduce the incidence of metachronous inguinal hernia (MIH.Methods: Boys under 2 years old with an initial unilateral inguinal hernia were enrolled in this study. In whom the width of the asymptomatic-sided spermatic cord was ≥0.5 cm, these patients underwent contralateral groin exploration. Age at initial operation, weight, initial operation side, the sonographic width of the spermatic cord, the operative findings and presence of MIH were recorded, and the relationship among them was studied. Boys in the US group underwent an open herniorrhaphy with pre-operative ultrasound examination; the non-US group included boys who did not undergo a pre-operative ultrasound examination. A receiver operator curve (ROC analysis was performed to evaluated predictive value of the sonographic width of the spermatic cord for contralateral hernia.Results: A total of 24 months' follow-up data were obtained from 1,793 boys (US group 1,162, non-US group 631. In the US group, the width of the hernia-sided spermatic cord (0.75 ± 0.18 cm was larger than the normal side (0.37 ± 0.05 cm, P < 0.001. And the width of normal side spermatic cord had no significant difference between the groups regarding other factors such as age and weight. In whom the width of the asymptomatic-sided spermatic cord was ≥0.5 cm, the corresponding incidence of CIH was 86.4% (57/66. The width of the spermatic cord predicted the presence of contralateral hernia with ROC area under the curve = 0.943 (95% CI = 0.919–0.966. The total incidence of MIH was 4.1% (74/1793. The incidence of MIH in the US group was 2.2% (25/1162 much lower than 7.8% (49/631 in the non-US group (P < 0.001.

    Full Text Available Rajiv K Chander,1 Thomas S Monahan1,2 1Section of Vascular Surgery, Department of Surgery, University of Maryland School of Medicine, 2Department of Surgery, Baltimore Veterans Affairs Medical Center, Baltimore, MD, USA Abstract: Duplex ultrasonography is the ideal modality to assess great saphenous vein insufficiency. Duplex ultrasonography incorporates both gray scale images to delineate anatomy and color-Doppler imaging that visualizes the flow of blood in a structure. Assessment of great saphenous vein requires definition of the anatomy, augmentation of flow, evaluation for both superficial and deep vein thrombosis, and determining the presence of reflux. Currently, evolution in the treatment of reflux also relies on ultrasound for the treatment of the disease. Understanding the utilization of the ultrasound for the diagnosis and treatment of greater saphenous vein reflux is important for practitioners treating reflux disease.

    Surgically treatable diseases contribute approximately 11% of disability-adjusted life years (DALYs) worldwide yet they remain a neglected public health priority in low- and middle-income countries (LMICs). Pediatric inguinal hernia is the most common congenital abnormality in newborns and a major cause of morbidity and mortality yet elective repair remains largely unavailable in LMICs. This study is aimed to determine the costs and cost-effectiveness of pediatric inguinal hernia repair (PIHR) in a low-resource setting. Medical costs of consecutive elective PIHRs were recorded prospectively at two centers in Uganda. Decision modeling was used to compare two different treatment scenarios (adoption of PIHR and non-adoption) from a provider perspective. A Markov model was constructed to estimate health outcomes under each scenario. The robustness of the cost-effectiveness results in the base case analysis was tested in one-way and probabilistic sensitivity analysis. The primary outcome of interest was cost per DALY averted by the intervention. Sixty-nine PIHRs were performed in 65 children (mean age 3.6 years). Mean cost per procedure was $86.68 US (95% CI 83.1-90.2 USD) and averted an average of 5.7 DALYs each. Incremental cost-effectiveness ratio was $12.41 per DALY averted. The probability of cost-effectiveness was 95% at a cost-effectiveness threshold of $35 per averted DALY. Results were robust to sensitivity analysis under all considered scenarios. Elective PIHR is highly cost-effective for the treatment and prevention of complications of hernia disease even in low-resource settings. PIHR should be prioritized in LMICs alongside other cost-effective interventions.

    Infra-red analysis of QCD in the Regge limit is argued to lead to confinement with chiral symmetry breaking. The resulting Pomeron depends strongly on the centre of the gauge group with SU(3) colour producing uniquely the experimentally observed even signature, factorizing, Pomeron. The critical Pomeron (asymptotic rising cross-sections) occurs when QCD is saturated with quarks. New calculations are reviewed showing strong evidence for the emergence of the critical Pomeron diffraction peak at present accelerator energies. This leads to exciting predictions for diffraction scattering at p antip collider energies which could become the most precise experimental confirmation of QCD

    Full Text Available Renal cell carcinoma (RCC had a tendency to extend into the renal vein and inferior vena cava, while extension into the gonadal vein has been rarely reported. Gonadal vein tumor thrombosis appears as an enhancing filling defect within the dilated gonadal vein anterior to the psoas muscle and shows an enhancement pattern identical to that of the original tumor. The possibility of gonadal vein thrombosis should be kept in mind when looking at an imaging study of patients with RCC

    Background Despite conservative treatment, hemorrhage from an intrahepatic branch of the portal vein can cause hemodynamic instability requiring urgent intervention. Purpose To retrospectively report the outcomes of hemodynamically significant portal vein bleeding after endovascular management. Material and Methods During a period of 15 years, four patients (2 men, 2 women; median age, 70.5 years) underwent angiography and embolization for iatrogenic portal vein bleeding. Causes of hemorrhage, angiographic findings, endovascular treatment, and complications were reported. Results Portal vein bleeding occurred after percutaneous liver biopsy (n = 2), percutaneous radiofrequency ablation (n = 1), and percutaneous cholecystostomy (n = 1). The median time interval between angiography and percutaneous procedure was 5 h (range, 4-240 h). Common hepatic angiograms including indirect mesenteric portograms showed active portal vein bleeding into the peritoneal cavity with (n = 1) or without (n = 2) an arterioportal (AP) fistula, and portal vein pseudoaneurysm alone with an AP fistula (n = 1). Successful transcatheter arterial embolization (n = 2) or percutaneous transhepatic portal vein embolization (n = 2) was performed. Embolic materials were n-butyl cyanoacrylate alone (n = 2) or in combination with gelatin sponge particles and coils (n = 2). There were no major treatment-related complications or patient mortality within 30 days. Conclusion Patients with symptomatic or life-threatening portal vein bleeding following liver-penetrating procedures can successfully be managed with embolization.

    To examine lymphogranuloma venereum (LGV) trends over time among men who have sex with men (MSM) visiting the Amsterdam sexually transmitted infection (STI) clinic; to investigate anal LGV symptomatology; and to examine the positivity and characteristics of anorectal and inguinal LGV. We included MSM consultations from whom a swab (from anorectum, bubo or an genital ulcer) was taken for Chlamydia trachomatis (Ct) screening. Anorectal swabs were taken from all MSM who reported receptive anorectal intercourse in the preceding 6 months. Ct positive samples were further tested with a pmpH PCR to identify L-genovars. Patient symptoms, clinical and anoscopic inflammatory signs, and STI co-infections were noted; Gram-stained anorectal mucosal smears were examined. Between January 2005 and June 2012, 48 570 consultations among MSM were conducted. In 3628/35 650 visits, anorectal Ct infections were diagnosed, including 411 anal LGV (1.2%). Moreover, 65/1649 genital ulcer swabs were Ct positive; 10 were inguinal LGV (0.6%) Since January 2011 a significant increase in the positivity of LGV occurred (p<0.0001). 89 (27.2%) anorectal LGV cases were asymptomatic. HIV prevalence among anorectal LGV cases was significantly higher (p=0.008) than among inguinal LGV cases. STI co-morbidity in anorectal LGV cases remained invariably high during the study period. Since January 2011, LGV positivity in MSM consultations in Amsterdam has risen significantly. The great majority comprise anal LGV; inguinal LGV is rare. Anal LGV is asymptomatic in a quarter of cases. In all MSM with anal Ct infections LGV should be excluded, irrespective of symptoms or inflammatory signs.

    Lichtenstein's tension free mesh hernioplasty is the commonly done open technique for inguinal hernias. As our hospital is in rural area, majority of patients are labourers, open hernias are commonly done. The present study was done by comparing Lichtenstein Mesh Repair (LMR) v/s Modified Bassini's repair (MBR) + Lichtenstein mesh repair (LMR) of direct Inguinal Hernias to compare the technique of both surgeries and its outcome like postoperative complications and recurrence rate. A comparative randomized study was conducted on patients reporting to MNR hospital, sangareddy with direct inguinal hernias. A total of fifty consecutive patients were included in this study of which, 25 patients were operated by LMR and 25 patients were operated by MBR+LMR and followed up for a period of two years. The outcomes of the both techniques were compared. Study involved 25 each of Lichtenstein's mesh repair (LMR) and modified bassini's repair (MBR) + LMR, over a period of 2 years. The duration of surgery for lichtenstein mesh repair is around 34.56 min compared to LMR+MBR, which is 47.56 min which was statistically significant (p-value is MBR group in POD 1, but not statistically significant (p-value is 0.0949) and from POD 7 the pain was almost similar in both groups. The recurrence rate is 2% for LMR and 0% for MBR+LMR. LMR+MBR was comparatively better than only LMR in all direct inguinal hernias because of low recurrence rate (0%) and low postoperative complications, which showed in our present study.

  12. Conventional tomographic hilar anatomy emphasizing the pulmonary veins

    Genereux, G.P.

    1983-01-01

    The pulmonary hili are a frequent site of interpretive uncertainty because of thir complex anatomy. The right hilar shadow relates primarily to the ascending and descending pulmonary arteries and the right superior pulmonary vein, whereas the left hilar density accrues from the left pulmonary artery, left descending pulmonary artery, and left superior pulmonary vein. The right and left superoir pulmonary veins are intimately associated with and inseparable from the arteries. Knowledge of the course of these veins facilitates their identification on conventional tomograms. The right and left inferior pulmonary veins lie behind the lower hili and contribute only a small increment to the normal hilar density; the horizontal course of these vessels readily distinguishes them from the vertically oriented lower lobe arteries. Prominence of both the right and left superior and inferior veins may cause hilar pseudotumors. Conventional tomograms are most helpful in understanding plain radiographs. A multiview approach in anteroposterior, 55 0 posterior oblique, and lateral projections is recommended for a complete assessment. Computed tomography in transaxial sections adds further understanding of spatial relations in the hili, including the contributions of the pulmonary veins

    True FISP (fast imaging with steady-state free precession) is a fast imaging technique that provides high SNR (signal to noise ratio) and excellent delineation of parenchymal organs. The contrast of True FISP depends on the mixture of T 2 /T 1 . Vessels with slow flow are usually displayed as high signal intensity on True FISP images. The purpose of this study was to optimize fat-suppressed (FS) segmented True FISP imaging for portal veins, hepatic veins, and bile ducts. FS segmented True FISP images were applied to the phantoms of liver parenchyma, saline, and oil with various flip angles (every 10 degrees from 5-65 degrees) and k-space segmentations (3, 15, 25, 51, 75, 99). Five healthy volunteers were also examined to get optimized flip angle and k-space segmentation. The largest flip angle, 65 degrees, showed the best contrast between the liver parenchyma phantom, saline, and oil. The largest segmentations, 99, provided the best contrast between a liver parenchyma phantom and saline. However, the signal of the oil phantom exceeded that of the liver parenchyma phantom with 99 segmentations. As a result, the flip angle of 65 degrees and 75 segments is recommended to get the best contrast between the liver parenchyma phantom and saline, while suppressing the signal of oil. The volunteer studies also support the phantom studies and showed excellent anatomical delineation of portal veins, hepatic veins, and bile ducts when using these parameters. We conclude that True FISP is potentially suitable for the imaging of portal veins, hepatic veins, and bile ducts. The flip angle of 65 degrees with 75 segments is recommended to optimize FS segmented True FISP images. (author)

    For open and endoscopic inguinal hernia surgery, it has been demonstrated that low-volume surgeons with fewer than 25 and 30 procedures, respectively, per year are associated with significantly more recurrences than high-volume surgeons with 25 and 30 or more procedures, respectively, per year. This paper now explores the relationship between the caseload and the outcome based on the data from the Herniamed Registry. The prospective data of patients in the Herniamed Registry were analyzed using the inclusion criteria minimum age of 16 years, male patient, primary unilateral inguinal hernia, TEP or TAPP techniques and availability of data on 1-year follow-up. In total, 16,290 patients were enrolled between September 1, 2009, and February 1, 2014. Of the participating surgeons, 466 (87.6 %) had carried out fewer than 25 endoscopic/laparoscopic operations (low-volume surgeons) and 66 (12.4 %) surgeons 25 or more operations (high-volume surgeons) per year. Univariable (1.03 vs. 0.73 %; p = 0.047) and multivariable analysis [OR 1.494 (1.065-2.115); p = 0.023] revealed that low-volume surgeons had a significantly higher recurrence rate compared with the high-volume surgeons, although that difference was small. Multivariable analysis also showed that pain on exertion was negatively affected by a lower caseload <25 [OR 1.191 (1.062-1.337); p = 0.003]. While here, too, the difference was small, the fact that in that group there was a greater proportion of patients with small hernia defect sizes may have also played a role since the risk in that group was higher. In this analysis, no evidence was found that pain at rest [OR 1.052 (0.903-1.226); p = 0.516] or chronic pain requiring treatment [OR 1.108 (0.903-1.361); p = 0.326] were influenced by the surgeon volume. As confirmed by previously published studies, the data in the Herniamed Registry also demonstrated that the endoscopic/laparoscopic inguinal hernia surgery caseload impacted the outcome. However

    The French Agency for Food, Environmental and Occupational Health and Safety (ANSES) reiterates that wind turbines emit infra-sounds (sound below 20 Hz) and low-frequency sounds. There are also other sources of infra-sound emissions that can be natural (wind in particular) or anthropogenic (heavy-goods vehicles, heat pumps, etc.). The measurement campaigns undertaken during the expert appraisal enabled these emissions from three wind farms to be characterised. In general, only very high intensities of infra-sound can be heard or perceived by humans. At the minimum distance (of 500 metres) separating homes from wind farm sites set out by the regulations, the infra-sounds produced by wind turbines do not exceed hearing thresholds. Therefore, the disturbance related to audible noise potentially felt by people around wind farms mainly relates to frequencies above 50 Hz. The expert appraisal showed that mechanisms for health effects grouped under the term 'vibro-acoustic disease', reported in certain publications, have no serious scientific basis. There have been very few scientific studies on the potential health effects of infra-sounds and low frequencies produced by wind turbines. The review of these experimental and epidemiological data did not find any adequate scientific arguments for the occurrence of health effects related to exposure to noise from wind turbines, other than disturbance related to audible noise and a nocebo effect, which can help explain the occurrence of stress-related symptoms experienced by residents living near wind farms. However, recently acquired knowledge on the physiology of the cochlea-vestibular system has revealed physiological effects in animals induced by exposure to high-intensity infra-sounds. These effects, while plausible in humans, have yet to be demonstrated for exposure to levels comparable to those observed in residents living near wind farms. Moreover, the connection between these physiological effects and the occurrence of

    Chang, Huai-Chien; Anilir, Serkan

    Currently, International Space Station (ISS) is capable to support 3 to 4 astronauts onboard for at least 6 months using an integrated life support system to support the need of crew onboard. Waste from daily life of the crew members are collected by waste recycle systems, electricity consumption depends on collecting solar energy, etc. though it likes the infrastructure we use on Earth, ISS can be comprehended nearly a self-reliant integrated architecture so far, this could be given an important hint for current architecture which is based on urban centralized infrastructure to support our daily lives but could be vulnerable in case of nature disasters. Comparatively, more and more economic activities and communications rely on the enormous urban central infrastructure to support our daily lives. Therefore, when in case of natural disasters, it may cut-out the infrastructure system temporarily or permanent. In order to solve this problem, we propose to design a temporary shelter, which is capable to work without depending on any existing infrastructure. We propose to use some closed-life-cycle or integrated technologies inspired by the possibilities of space and other emerging technologies into current daily architecture by using Infra-free® design framework; which proposes to integrate various life supporting infrastructural elements into one-closed system. We try to work on a scenario for post-disaster management housing as the method for solving the lifeline problems such as solid and liquid waste, energy, and water and hygiene solution into one system. And trying to establish an Infra-free® model of shelter for disaster area. The ultimate objective is to design a Temp Infra-free® model dealing with the sanitation and environment preservation concerns for disaster area.

  18. Endovascular Radiofrequency Ablation for Varicose Veins

    2011-01-01

    Executive Summary Objective The objective of the MAS evidence review was to conduct a systematic review of the available evidence on the safety, effectiveness, durability and cost–effectiveness of endovascular radiofrequency ablation (RFA) for the treatment of primary symptomatic varicose veins. Background The Ontario Health Technology Advisory Committee (OHTAC) met on August 26th, 2010 to review the safety, effectiveness, durability, and cost-effectiveness of RFA for the treatment of primary symptomatic varicose veins based on an evidence-based review by the Medical Advisory Secretariat (MAS). Clinical Condition Varicose veins (VV) are tortuous, twisted, or elongated veins. This can be due to existing (inherited) valve dysfunction or decreased vein elasticity (primary venous reflux) or valve damage from prior thrombotic events (secondary venous reflux). The end result is pooling of blood in the veins, increased venous pressure and subsequent vein enlargement. As a result of high venous pressure, branch vessels balloon out leading to varicosities (varicose veins). Symptoms typically affect the lower extremities and include (but are not limited to): aching, swelling, throbbing, night cramps, restless legs, leg fatigue, itching and burning. Left untreated, venous reflux tends to be progressive, often leading to chronic venous insufficiency (CVI). A number of complications are associated with untreated venous reflux: including superficial thrombophlebitis as well as variceal rupture and haemorrhage. CVI often results in chronic skin changes referred to as stasis dermatitis. Stasis dermatitis is comprised of a spectrum of cutaneous abnormalities including edema, hyperpigmentation, eczema, lipodermatosclerosis and stasis ulceration. Ulceration represents the disease end point for severe CVI. CVI is associated with a reduced quality of life particularly in relation to pain, physical function and mobility. In severe cases, VV with ulcers, QOL has been rated to be as bad

    Direct brow lift surgery remains popular among Asian women despite its disadvantages. The traditional direct brow lift by a supra-brow incision is not suitable for Asian women because of their unique facial features, such as higher eyebrows, wider upper eyelids, and more orbital fat. Therefore, we designed a novel brow lift technique via a supra-brow combined with an infra-brow approach for Asian women. An area of skin above and below the eyebrow was measured, demarcated, and surgically removed. The redundant orbicularis oculi muscle (OOM) was excised while keeping the frontalis muscle intact. The OOM in the inferior flap was elevated and sutured to the frontalis muscle. In cases of puffy eyelids, orbital fat was partially removed through an infra-brow incision. Finally, a series of modifications were performed to reduce post-operative scarring. A total of 496 patients underwent this surgery from July 2009 to December 2013 and 432 patients were followed up for at least 6 months after surgery. Post-operative scars, in most patients (428/432), were inconspicuous. There were no facial nerve injuries documented and eight patients reported transient forehead numbness. The height of the palpebral fissure was increased but there was no marked increase observed of the distance between the upper eyelid edge and the eyebrow. In follow-up visits, 409 out of 432 patients (94.7 %) were satisfied with their surgical results. This new brow lift technique via a supra-brow combined with an infra-brow approach provided a simple and safe surgical repair of lateral brow ptosis, upper eyelids hooding, and crows' feet in Asian women. The surgical outcomes were predictable and the scars were inconspicuous. This journal requires that authors assign a level of evidence to each article.

    1995-09-01

    We evaluated the use of sonography as a means of assessing hernial occlusion and possible postoperative changes such as hematomas or seromas in the inguinal and scrotal regions after 1139 laparoscopic repairs of hernias between August 1992 and November 1994. Changes after laparoscopic hernia repair were found in 307 patients (27%). Hematomas or seromas were seen in 132 patients, protrusion of the prosthetic mesh in 17, mesh infection in two, and small bowel entrapment in an insufficient peritoneal suture in two. Recurrences were diagnosed correctly in six patients, mobile preperitoneal lipomas in five. Sonography is useful in the evaluation of complications after laparoscopic hernia repair, including recurrent hernia. In the absence of symptoms, sonography is not indicated.

    2013-01-01

    The formation of leaf vein patterns has fascinated biologists for centuries. Transport of the plant signal auxin has long been implicated in vein patterning, but molecular details have remained unclear. Varied evidence suggests a central role for the plasma-membrane (PM)-localized PIN-FORMED1 (PIN1) intercellular auxin transporter of Arabidopsis thaliana in auxin-transport-dependent vein patterning. However, in contrast to the severe vein-pattern defects induced by auxin transport inhibitors, pin1 mutant leaves have only mild vein-pattern defects. These defects have been interpreted as evidence of redundancy between PIN1 and the other four PM-localized PIN proteins in vein patterning, redundancy that underlies many developmental processes. By contrast, we show here that vein patterning in the Arabidopsis leaf is controlled by two distinct and convergent auxin-transport pathways: intercellular auxin transport mediated by PM-localized PIN1 and intracellular auxin transport mediated by the evolutionarily older, endoplasmic-reticulum-localized PIN6, PIN8, and PIN5. PIN6 and PIN8 are expressed, as PIN1 and PIN5, at sites of vein formation. pin6 synthetically enhances pin1 vein-pattern defects, and pin8 quantitatively enhances pin1pin6 vein-pattern defects. Function of PIN6 is necessary, redundantly with that of PIN8, and sufficient to control auxin response levels, PIN1 expression, and vein network formation; and the vein pattern defects induced by ectopic PIN6 expression are mimicked by ectopic PIN8 expression. Finally, vein patterning functions of PIN6 and PIN8 are antagonized by PIN5 function. Our data define a new level of control of vein patterning, one with repercussions on other patterning processes in the plant, and suggest a mechanism to select cell files specialized for vascular function that predates evolution of PM-localized PIN proteins.

    Deep medullary veins support the venous drainage of the brain and may display abnormalities in the context of different cerebrovascular diseases. We present and evaluate a method to automatically detect and quantify deep medullary veins at 7 T. Five participants were scanned twice, to assess the robustness and reproducibility of manual and automated vein detection. Additionally, the method was evaluated on 24 participants to demonstrate its application. Deep medullary veins were assessed within an automatically created region-of-interest around the lateral ventricles, defined such that all veins must intersect it. A combination of vesselness, tubular tracking, and hysteresis thresholding located individual veins, which were quantified by counting and computing (3-D) density maps. Visual assessment was time-consuming (2 h/scan), with an intra-/inter-observer agreement on absolute vein count of ICC = 0.76 and 0.60, respectively. The automated vein detection showed excellent inter-scan reproducibility before (ICC = 0.79) and after (ICC = 0.88) visually censoring false positives. It had a positive predictive value of 71.6 %. Imaging at 7 T allows visualization and quantification of deep medullary veins. The presented method offers fast and reliable automated assessment of deep medullary veins. (orig.)

    Full Text Available Abstract Background Ultrasound guidance for central and peripheral venous access has been proven to improve success rates and reduce complications of venous cannulation. Appropriately trained and experienced operators add significantly to diminished patient morbidity related to venous access procedures. We discuss a patient who required an arterial stent-graft to prevent arterial hemorrhage following inadvertent cannulation of the proximal, ventral, right subclavian artery related to unsuccessful ultrasound guided access of the subclavian vein. Case presentation During pre-operative preparation for aortic valve replacement and aorto-coronary bypass surgery an anesthetist attempted ultrasound guided venous access. The ultrasound guided attempt to access the right jugular vein failed and the ultrasound guided attempt at accessing the subclavian vein resulted in inappropriate placement of an 8.5 F sheath in the arterial system. Following angiographic imaging and specialist consultations, an arterial stent-graft was deployed in the right subclavian artery rather than perform an extensive anterior chest wall resection and dissection to extract the arterial sheath. The patient tolerated the procedure, without complication, despite occlusion of the right internal mammary artery and the right vertebral artery. There were no neurologic sequelae. There was no evidence of hemorrhage after subclavian artery sheath extraction and stent-graft implantation. Conclusion The attempted ultrasound guided puncture of the subclavian vein resulted in placement of an 8.5 F subclavian artery catheter. Entry of the catheter into the proximal subclavian artery beneath the medial clavicle, the medial first rib and the manubrium suggests that the operator, most likely, did not directly visualize the puncture needle enter the vessel with the ultrasound. The bones of the anterior chest impede the ultrasound beam and the vessels in this area would not be visible to ultrasound

    Full Text Available Background: The present clinical trial was designed to compare the results of bilateral inguinal hernia repair between patients who underwent the conventional Stoppa technique and laparoscopic total extraperitoneal repair (LTE with a single mesh and without staple fixation. Patients and Methods: This controlled, randomised clinical trial was conducted at General Surgery and Trauma of the Clinics Hospital, Medical School, the University of São Paulo between September 2010 and February 2011. Totally, 50 male patients, with a bilateral inguinal hernia, older than 25 years were considered eligible for the study. The following parameters were analysed during the early post-operative period: (1 The intensity of surgical trauma, operation time, C-reactive protein (CRP levels, white blood cell count, bleeding and pain intensity; (2 quality of life assessment; and (3 post-operative complications. Results: LTE procedure was longer than the Stoppa procedure (134.6 min ± 38.3 vs. 90.6 min ± 41.3; P 0.05. There was no difference in pain during the 1st and 7th post-operative, physical functioning, physical limitation, the impact of pain on daily activities, and the Carolinas Comfort Scale during the 7th and 15th post-operative (P > 0.05. Complications occurred in 88% of Stoppa group (22 patients and 64% in LTE group (16 patients (P < 0.05. Conclusion: The comparative study between the Stoppa and LTE approaches for the bilateral inguinal hernia repair demonstrated that: (1 The LTE approach showed less surgical trauma despite the longer operation time; (2 Quality of life during the early post-operative period were similar; and (3 Complication rates were higher in the Stoppa group.

    Full Text Available The process of recanalization of the veins of the lower limbs after an episode of acute deep venous thrombosis is part of the natural evolution of the remodeling of the venous thrombus in patients on anticoagulation with heparin and vitamin K inhibitors. This remodeling involves the complex process of adhesion of thrombus to the wall of the vein, the inflammatory response of the vessel wall leading to organization and subsequent contraction of the thrombus, neovascularization and spontaneous lysis of areas within the thrombus. The occurrence of spontaneous arterial flow in recanalized thrombosed veins has been described as secondary to neovascularization and is characterized by the development of flow patterns characteristic of arteriovenous fistulae that can be identified by color duplex scanning. In this review, we discuss some controversial aspects of the natural history of deep vein thrombosis to provide a better understanding of its course and its impact on venous disease.

    1997-12-01

    In a prospective randomized trial comparing the totally preperitoneal (TPP) laparoscopic approach and the Stoppa procedure (open), 100 patients with inguinal hernias (Nyhus IIIA, IIIB, IV) were followed over a 3-year period. Both groups were epidemiologically comparable. In the laparoscopic group, operating time was significantly longer (p = 0.01), but hospital stay (3.2 vs. 7.3 days) and delay in return to work (17 vs. 35 days) were significantly reduced (p = 0.01). Postoperative comfort (less pain) was better (p = 0.001) after laparoscopy. In this group, morbidity was also reduced (4 vs. 20%; p = 0.02). The mean follow-up was 605 days, and 93% of the patients were reviewed at 3 years. There were three (6%) recurrences after TPP, especially at the beginning of the surgeon's learning curve, versus one for the Stoppa procedure (NS). For bilateral hernias, the authors suggest the use of a large prosthesis rather than two small ones to minimize the likelihood of recurrence. In the conditions described, the laparoscopic (TPP) approach to inguinal hernia treatment appears to have the same long-term recurrence rate as the open (Stoppa) procedure but a real advantage in the early postoperative period.

    2004-01-01

    To evaluate the usefulness of the impedance index of the renal vein for the diagnosis of acute obstructive uropathy in rabbits. Ligation of the left ureter was done in 12 rabbits. Doppler sonography of the interlobar veins in both kidneys was checked before and 30 minutes, 1, 3, 6, 9 and 24 hours after ureteral ligation. The venous impedance index [(peak flow signal-least flow signal)/peak flow signal] was compared between the obstructed and non-obstructed kidneys for all periods. The change in the impedance index after ureteral ligation was also compared between the obstructed and non-obstructed kidneys. A decrease in the impedance index of the intrarenal vein was observed starting from 30 mins atter ureteral ligation, and the index remained low up to 24 hours after ureteral ligation. The obstructed kidneys had a significantly lower impedance index than the contralateral kidneys for all six of the postligation measurements (p< 0.05). There were significant differences in the change of impedance index after ureteral ligation between the obstructed and non-obstructed kidneys (p< 0.05). The impedance index of the intrarenal vein was significantly decreased in the obstructed kidneys. The measurement of the impedance index of the intrarenal vein using Doppler sonography could provide a useful method of diagnosing obstructive uropathy

    Full Text Available Aim. Although inguinal hernia repair is the most frequently performed surgical procedure in the world, the best repair method has not gained acceptance yet. The ideal repair must be safe, simple, and easy to perform and require minimal dissection which provides enough exploration, maintain patient’s comfort in the early stage, and also be cost-effective, reducing operation costs, labor loss, hospital stay, and recurrence. Materials and Methods. There were eighty-five patients between the ages of 18 and 75, diagnosed with inguinal hernia in our clinic. Lichtenstein procedure for hernia repair was performed under spinal anesthesia in all patients. Forty-two patients had the standard procedure and, in 43 patients, the polypropylene mesh was used without fixation. All patients were examined and questioned on the 7th day of the operation in terms of pain, scrotal edema, and the presence of seroma and later on in the 6th postoperative month in terms of paresthesia, neuropraxia, and recurrence by a single physician. Results. Operative time and pain scores in the nonfixation group were significantly lower, without any increase in rates of recurrence. Conclusion. Based on these findings, in Lichtenstein hernia repair method, nonfixation technique can be used safely with better results.

    1998-01-01

    Purpose: To develop an animal model of acute deep vein thrombosis (DVT). Methods: In part I of the study nine juvenile domestic pigs were used. Each external iliac vein was transluminally occluded with a balloon catheter. Thrombin was infused through a microcatheter in one leg according to one of the following protocols: (1) intraarterial (IA): 1250 U at 25 U/min in the common femoral artery (n= 3); (2) intravenous (IV): 5000 U in the popliteal vein at 500 U/min (n= 3), or at 100 U/min (n= 3). Saline was administered in the opposite leg. After the animals were killed, the mass of thrombus in the iliofemoral veins was measured. The pudendoepiploic (PEV), profunda femoris (PF), and popliteal veins (PV) were examined. Thrombosis in the tributaries of the superficial femoral vein (SFVt) was graded according to a three-point scale (0, +, ++). In part II of the study IV administration was further investigated in nine pigs using the following three regimens with 1000 U at 25 U/min serving as the control: (1) 1000 U at 100 U/min, (2) 250 U at 25 U/min, (3) 250 U at 6.25 U/min. Results: All animals survived. In part I median thrombus mass in the test limbs was 1.40 g as compared with 0.25 g in the controls (p= 0.01). PEV, PFV and PV were thrombosed in all limbs infused with thrombin. IV infusion was more effective in inducing thrombosis in both the parent veins (mass 1.32-1.78 g) and SVFt (++ in 4 of 6 legs), as compared with IA infusion (mass 0.0-1.16 g; SFVt ++ in 1 of 3 legs). In part II thrombus mass in axial veins ranged from 1.23 to 2.86 g, and showed no relationship with the dose of thrombin or the rate of infusion. Tributary thrombosis was less extensive with 250 U at 25 U/min than with the other regimens. Conclusion: Slow distal intravenous thrombin infusion in the hind legs of pigs combined with proximal venous occlusion induces thrombosis in the leg veins that closely resembles clinical DVT in distribution

    2016-01-01

    Full Text Available We are reporting a case of a healthy 21-year-old male, with no significant past medical history, who was found to have an incidental nonocclusive deep vein thrombosis in the right internal jugular vein detected on a head MRI previously ordered for work-up of headaches. A follow-up upper extremity venous Doppler ultrasound confirmed the presence of a partially occlusive deep vein thrombosis in the right jugular vein. The case presented is unique for the reason that the patient is young and has no prior risk factor, personal or familial, for venous thrombosis except for associated polycythemia on clinical presentation.

  16. Veins improve fracture toughness of insect wings.

    Directory of Open Access Journals (Sweden)

    Jan-Henning Dirks

    Full Text Available During the lifetime of a flying insect, its wings are subjected to mechanical forces and deformations for millions of cycles. Defects in the micrometre thin membranes or veins may reduce the insect's flight performance. How do insects prevent crack related material failure in their wings and what role does the characteristic vein pattern play? Fracture toughness is a parameter, which characterises a material's resistance to crack propagation. Our results show that, compared to other body parts, the hind wing membrane of the migratory locust S. gregaria itself is not exceptionally tough (1.04±0.25 MPa√m. However, the cross veins increase the wing's toughness by 50% by acting as barriers to crack propagation. Using fracture mechanics, we show that the morphological spacing of most wing veins matches the critical crack length of the material (1132 µm. This finding directly demonstrates how the biomechanical properties and the morphology of locust wings are functionally correlated in locusts, providing a mechanically 'optimal' solution with high toughness and low weight. The vein pattern found in insect wings thus might inspire the design of more durable and lightweight artificial 'venous' wings for micro-air-vehicles. Using the vein spacing as indicator, our approach might also provide a basis to estimate the wing properties of endangered or extinct insect species.

    To present the clinical management of inguinal disruption in a professional hockey player and highlight the importance of a multidisciplinary approach to diagnosis and management. A professional hockey player with recurrent groin pain presented to the clinic after an acute exacerbation of pain while playing hockey. The patient received a clinical diagnosis of inguinal disruption. Imaging revealed a tear in the rectus abdominis. Management included two platelet-rich plasma (PRP) injections to the injured tissue, and subsequent manual therapy and exercise. The patient returned to his prior level of performance in 3.5 weeks. This case demonstrated the importance of a multidisciplinary team and the need for advanced imaging in athletes with groin pain. Research quality concerning the non-surgical management of inguinal disruption remains low. This case adds evidence that PRP, with the addition of manual therapy and exercise may serve as a relatively quick and effective non-surgical management strategy.

    Computed tomography and pornographic findings of 63 patients with hepatoma, undergone hepatic angiography and superior mesenteric pornography for evaluation of tumor and thrombosis of portal vein and determination of indication of transcatheter arterial embolization for palliative treatment of hepatoma from April, 85 to June, 86 in Hanyang university hospital, were reviewed. The results were as follows: 1. In 36 cases, portal vein thrombosis was detected during photography. Nineteen of 37 cases which revealed localized hepatoma in the right lobe of the liver showed portal vein thrombosis; 9 of 11 cases of the left lobe; 8 of 14 cases which were involved in entire liver revealed thrombosis. One case localized in the caudate lobe showed no evidence of invasion to portal vein. 2. Twenty-four of 34 cases with diffuse infiltrative hepatoma revealed portal vein thrombosis and the incidence of portal vein thrombosis in this type were higher than in the cases of the nodular type. 3. The portal vein thrombosis appeared as filling defects of low density in the lumen of the portal veins in CT and they did not reveal contrast enhancement. 4. CT revealed well the evidence of obstructions in the cases of portal vein thrombosis and the findings were well-corresponded to the findings of the superior mesenteric photography. 5. Five of the cases of the portal vein thrombosis were missed in the CT and the causes were considered as due to partial volume effect of enhanced portal vein with partial occlusion or arterioportal shunts. 6. Six of 13 cases with occlusion of main portal vein showed cavernous transformation and they were noted as multiple small enhanced vascularities around the porta hepatis in the CT. According to the results, we conclude that CT is a useful modality to detect the changes of the portal veins in the patients of the hepatoma.

    2014-01-01

    Objective: To modify the technique of basilic vein transposition for vascular accesss for haemodialysis aiming at better maturation rate, longer survival of fistula and lesser complications. Study Design: Case series. Place and Duration of Study: Shaikh Zayed Hospital and Omer Hospital, Lahore, from February 2008 to July 2011. Methodology: Patients referred for basilic vein transposition for haemodialysis vascular access were prospectively enrolled. The surgical technique included small tracking incisions, an extra 3 - 4 cm of vein length harvesting to avoid tension in the vein in its new course, an oval arteriotomy and a smooth curved pathway, away from vein harvesting incision to avoid entrapment of vein in the scar. Maturation rate, fistula survival and other complications were noted. Results: There was no immediate failure in 51 patients. The complications during follow-up period were infection and thrombosis, bleeding and non-development of basilic vein in 2 patients each; and false aneurysm formation in one. Four patients died during follow-up period. The maturation time was 4.9 A +- 1.1 weeks. The early patency rate was 92.2%, same at 6 months and 90.7% at 12 months. Conclusion: Arteriovenous fistula constructed with modified technique of basilic vein transposition is an acceptable and valid option of vascular access for haemodialysis. (author)

    2008-01-01

    This evidence-based review of the literature aims to answer two questions regarding inguinal hernia repair: 1. should a prosthetic patch be used routinely? 2. Which approach is better - laparoscopic or open surgery? After a comprehensive search of electronic databases we retained only meta-analyses (n=14) and/or randomised clinical trials (n=4). Review of this literature suggests with a good level of evidence that prosthetic hernia repair is the gold standard; the laparoscopic approach has very few proven benefits and may involve more serious complications when performed outside expert centers. The role of laparoscopy for the repair of bilateral or recurrent hernias needs better evaluation.

    Full Text Available Introduction. De Garengeot first described a femoral hernia containing the appendix in 1731. Appendicitis occurring in this rare clinical setting represents a challenge in diagnosis and management. Case Presentation. We present the case of a 71-year-old male with a three-day history of a nontender inguinal mass. Computed tomography (CT suggested a femoral hernia. Intraoperatively, the hernia sac was noted to contain a perforated appendix. Discussion. This is an infrequently reported clinical scenario and only the 14th reported case in peer-reviewed literature which includes preoperative CT images. Our case adds to previously reported low sensitivity of CT for diagnosing De Garengeot’s hernia. Furthermore, unlike our case the vast majority of previous reports noted a painful inguinal swelling. Conclusion. Perforated appendicitis in a femoral hernia is an extremely uncommon presentation. However, consideration should be given to De Garengeot’s hernia in patients with a groin mass, even if nontender.

    Full Text Available OBJECTIVES: Analyze the anatomic variations of the testicular veins in human cadavers and fetuses. MATERIALS AND METHODS: One hundred male adult cadavers and 24 fetuses were studied. Four anatomic aspects were considered: 1 Number of testicular veins, 2 The local of vein termination, 3 Type and number of collaterals present and 4 Testicular vein termination angle. RESULTS: Cadavers - Right side - One testicular vein occurred in 85% and 2 veins in 5% of the cases. There were communicating veins with the colon in 21% of the cases. Left side - One testicular vein occurred in 82%, two veins in 15%, three veins in 2% and four veins in 1% of the cases. There were communicating veins with the colon in 31% of the cases. Fetuses - Right side -One testicular vein occurred in all cases. This vein drained to the vena cava in 83.3% of the cases, to the junction of the vena cava with the renal vein in 12.5% and to the renal vein in 4.2%. There were communicating veins with the colon in 25% of the cases. Left side - One testicular vein occurred in 66.6% of the cases, and 2 veins in occurred 33.3%. Communicating veins with the colon were found in 41.6% of the cases. CONCLUSION: The testicular vein presents numeric variations and also variations in its local of termination. In approximately 30% of the cases, there are collaterals that communicate the testicular vein with retroperitoneal veins. These anatomic findings can help understanding the origin of varicocele and its recurrence after surgical interventions.

    The ability of physicians to identify a patent processus vaginalis by laparoscopic examination of the internal ring is now well established, but the efficacy on patient outcome is not. The authors reviewed their experience to determine the effect of diagnostic laparoscopy of the internal ring on the management of children with inguinal hernias. The records of 150 children who underwent inguinal surgery were reviewed--75 before (group 1) and 75 after (group 2) pediatric laparoscopy was introduced into the authors' practice. The children in group 1 were selected for unilateral or bilateral surgery based on history, age, sex, side of presentation, and parental preference. For group 2, laparoscopy was an additional option offered to appropriate patients. Laparoscopy was performed in 43 group 2 patients, using an infraumbilical site. The minimum follow-up period was 2 years for group 1 and 1 year for group 2. The mean ages for groups 1 and 2 were 41.2 and 39.7 months, respectively. There were 61 boys and 14 girls in each group. The percentages of right (R), left (L), and bilateral (B) findings, based on clinical observation, were 56.0 (R), 29.3 (L), and 14.7 (B) for group 1, and 58.7 (R), 26.6 (L), and 14.7 (B) for group 2. The incidence of bilateral surgical exploration was similar for the two groups (group 1, 58.6%; group 2, 61.3%). The addition of laparoscopy significantly lowered the incidence of negative explorations (group 1, 16.0%; group 2, 2.6%; P < .01).(ABSTRACT TRUNCATED AT 250 WORDS)

    The commonly used Darling classification for total anomalous pulmonary venous connection (TAPVC) consists of supracardiac, cardiac, infracardiac, and mixed types (Craig et al., Lab Invest 6:44-64, 1967). In supracardiac TAPVC, the common pulmonary vein drains superiorly into the left innominate vein, the superior vena cava, or the azygos vein by way of an ascending vertical vein. We describe a case of supracardiac TAPVC draining into the azygos vein atypically by way of a descending vertical vein.

    Varicocele, a varicose enlargement of the veins in the spermatic cord, is found in 21-39% of men being evaluated for infertility. Thermometric detection of this condition was attempted by microwave radiometry as well as by contact thermometry using thermistor probes. The inguinal and scrotal regions of 44 male subject and inguinal regions of 11 female subjects were studied. Substantially different thermal patterns were obtained by thermistors (surface temperature) and microwave radiometry (subsurface temperature). There was a correlation between left scrotal varicocele and a temperature elevation of the left spermatic cord using microwave radiometry.

    An encephalocele is a protrusion of the brain and/or meninges through a defect in the skull that is closed or covered with skin. Occipital encephaloceles are the most frequent type in North America and Western Europe, where about 85% of encephaloceles take this form. To the best of our knowledge, there are only three other reported cases of double occipital encephaloceles in the literature. The current study reports a double and both supra- and infra-torcular occipital encephalocele in a neonate and discusses the importance of preoperative neuroimaging studies to optimize the outcome. The patient was a 1-day-old male child who was identified by prenatal ultrasound to have two occipital encephaloceles. The patient underwent a closure of the occipital encephalocele on the second postnatal day. The infant tolerated the procedure well and was extubated on the first postoperative day. The child continues to do well during follow-up. Copyright © 2014 Sociedad Española de Neurocirugía. Published by Elsevier España. All rights reserved.

    To determine the cost-effectiveness of laparoscopic inguinal hernia repair. Laparoscopic inguinal hernia repair seems superior to open techniques with respect to short-term results. An issue yet to be studied in depth remains the cost-effectiveness of the procedure. As part of a multicenter randomized study in which >1000 patients were included, a cost-effectiveness analysis from a societal point of view was performed. After informed consent, all resource costs, both in and outside the hospital, for patients between August 1994 and July 1995 were recorded prospectively. Actual costs were calculated in a standardized fashion according to international guidelines. The main measures used for the evaluation of inguinal hernia repair were the number of averted recurrences and quality of life measured with the Short Form 36 questionnaire. Resource costs were recorded for 273 patients, 139 in the open and 134 in the laparoscopic group. Both groups were comparable at baseline. Average total hospital costs were Dfl 1384.91 (standard deviation: Dfl 440.15) for the open repair group and Dfl 2417.24 (standard deviation: Dfl 577.10) for laparoscopic repair, including a disposable kit of Dfl 676. Societal costs, including costs for days of sick leave, were lower for the laparoscopic repair and offset the hospital costs by Dfl 780.83 (75.6%), leaving the laparoscopic repair Dfl 251.50 more expensive (Dfl 4665 versus Dfl 4916.50). At present, the recurrence rate is 2.6% lower after laparoscopic repair. Thus, 38 laparoscopic repairs, costing an additional Dfl 9,557, prevent the occurrence of one recurrent hernia. Quality of life was better after laparoscopic repair. A better quality of life in the recovery period and the possibility of replacing parts of the disposable kit with reusable instruments may result in the laparoscopic repair becoming dominantly better--that is, less expensive and more effective from a societal perspective.

    Full Text Available Background: Incarcerated inguinal hernia is a commonly encountered urgent surgical condition, and tension-free repair is a well-established method for the treatment of noncomplicated cases. However, due to the risk of prosthetic material-related infections, the use of mesh in the repair of strangulated or incarcerated hernia has often been subject to debate. Recent studies have demonstrated that biomaterials represent suitable materials for performing urgent hernia repair. Certain studies recommend mesh repair only for cases where no bowel resection is required; other studies, however, recommend mesh repair for patients requiring bowel resection as well. Aim: The aim of this study was to compare the outcomes of different surgical techniques performed for strangulated hernia, and to evaluate the effect of mesh use on postoperative complications. Study Design: Retrospective cross-sectional study. Methods: This retrospective study was performed with 151 patients who had been admitted to our hospital’s emergency department to undergo surgery for a diagnosis of incarcerated inguinal hernia. The patients were divided into two groups based on the applied surgical technique. Group 1 consisted of 112 patients treated with mesh-based repair techniques, while Group 2 consisted of 39 patients treated with tissue repair techniques. Patients in Group 1 were further divided into two sub-groups: one consisting of patients undergoing bowel resection (Group 3, and the other consisting of patients not undergoing bowel resection (Group 4. Results: In Group 1, it was observed that eight (7.14% of the patients had wound infections, while two (1.78% had hematomas, four (3.57% had seromas, and one (0.89% had relapse. In Group 2, one (2.56% of the patients had a wound infection, while three (7.69% had hematomas, one (2.56% had seroma, and none had relapses. There were no statistically significant differences between the two groups with respect to wound infection

    Authentication using finger vein pattern has substantial advantage than other biometrics. Because human vein patterns are hidden inside the skin and tissue, it is hard to forge vein structure. But conventional system using NIR LED array has two drawbacks. First, direct contact with LED array raise sanitary problem. Second, because of discreteness of LEDs, non-uniform illumination exists. We propose non-contact finger vein acquisition system using NIR laser and Laser line generator lens. Laser line generator lens makes evenly distributed line laser from focused laser light. Line laser is aimed on the finger longitudinally. NIR camera was used for image acquisition. 200 index finger vein images from 20 candidates are collected. Same finger vein pattern extraction algorithm was used to evaluate two sets of images. Acquired images from proposed non-contact system do not show any non-uniform illumination in contrary with conventional system. Also results of matching are comparable to conventional system. We developed Non-contact finger vein acquisition system. It can prevent potential cross contamination of skin diseases. Also the system can produce uniformly illuminated images unlike conventional system. With the benefit of non-contact, proposed system shows almost equivalent performance compared with conventional system.

    To review the literature related to the management of reticular varices and telangiectases of the lower limbs to provide guidance on the treatment of these veins. Very few randomised clinical trials are available in this field. A European Guideline has been published on the treatment of reticular varices and telangiectases, which is largely based on the opinion of experts. Older accounts written by individual phlebologists contain extensive advice from their own practice, which is valuable in identifying effective methods of sclerotherapy. All accounts indicate that a history should be taken combined with a clinical and ultrasound examination to establish the full extent of the venous disease. Sclerotherapy is commenced by injecting the larger veins first of all, usually the reticular varices. Later in the same session or in subsequent sessions, telangiectases can be treated by direct injection. Following treatment, the application of class 2 compression stockings for a period of up to three weeks is beneficial but not used universally by all phlebologists. Further sessions can follow at intervals of 2-8 weeks in which small residual veins are treated. Resistant veins can be managed by ultrasound-guided injection of underlying perforating veins and varices. Other treatments including RF diathermy and laser ablation of telangiectases have very limited efficacy in this condition. Sclerotherapy, when used with the correct technique, is the most effective method for the management of reticular varices and telangiectases. © The Author(s) 2015.

    The adrenal veins may present with a multitude of anatomical variants, which surgeons must be aware of when performing adrenalectomies. The adrenal veins originate during the formation of the prerenal inferior vena cava (IVC) and are remnants of the caudal portion of the subcardinal veins, cranial to the subcardinal sinus in the embryo. The many communications between the posterior cardinal, supracardinal, and subcardinal veins of the primordial venous system provide an explanation for the variable anatomy. Most commonly, one central vein drains each adrenal gland. The long left adrenal vein joins the inferior phrenic vein and drains into the left renal vein, while the short right adrenal vein drains immediately into the IVC. Multiple variations exist bilaterally and may pose the risk of surgical complications. Due to the potential for collaterals and accessory adrenal vessels, great caution must be taken during an adrenalectomy. Adrenal venous sampling, the gold standard in diagnosing primary hyperaldosteronism, also requires the clinician to have a thorough knowledge of the adrenal vein anatomy to avoid iatrogenic injury. The adrenal vein acts as an important conduit in portosystemic shunts, thus the nature of the anatomy and hypercoagulable states pose the risk of thrombosis. © 2014 Wiley Periodicals, Inc.

    Introduction Lichtenstein’s tension free mesh hernioplasty is the commonly done open technique for inguinal hernias. As our hospital is in rural area, majority of patients are labourers, open hernias are commonly done. The present study was done by comparing Lichtenstein Mesh Repair (LMR) v/s Modified Bassini’s repair (MBR) + Lichtenstein mesh repair (LMR) of direct Inguinal Hernias to compare the technique of both surgeries and its outcome like postoperative complications and recurrence rate. Materials and Methods A comparative randomized study was conducted on patients reporting to MNR hospital, sangareddy with direct inguinal hernias. A total of fifty consecutive patients were included in this study of which, 25 patients were operated by LMR and 25 patients were operated by MBR+LMR and followed up for a period of two years. The outcomes of the both techniques were compared. Results Study involved 25 each of Lichtenstein’s mesh repair (LMR) and modified bassini’s repair (MBR) + LMR, over a period of 2 years. The duration of surgery for lichtenstein mesh repair is around 34.56 min compared to LMR+MBR, which is 47.56 min which was statistically significant (p-value is MBR group in POD 1, but not statistically significant (p-value is 0.0949) and from POD 7 the pain was almost similar in both groups. The recurrence rate is 2% for LMR and 0% for MBR+LMR. Conclusion LMR+MBR was comparatively better than only LMR in all direct inguinal hernias because of low recurrence rate (0%) and low postoperative complications, which showed in our present study.

    Objective: To evaluate the interventional methods for occlusive hepatic veins in Budd-Chiari syndrome and its mid and long-term effects. Methods: Forty-two patients (male 17 cases and female 25 cases) aged from 18 to 57 years old (mean 34.5 years) were studied. The liver functions were Child A in 23 cases, Child B in 6 cases, and Child C in 13 cases, respectively. A total of 92 hepatic veins were occluded. Among them, 29 left hepatic veins, 24 middle hepatic veins, 36 right hepatic veins, and 3 accessory hepatic veins were occluded. Thirty-four patients were accompanied with the stenotic or occlusive inferior vena cave (IVC) . The interventional methods included: (1) recanalization of occlusive hepatic veins (by transjugular, transfemoral, and percutaneous transhepatic route, or the combination of above three methods); (2) percutaneous transluminal angioplasty; (3) self-expanding stent implantation. The occlusive IVC in 32 patients also accepted PTA and/or stent implantation. Results: The successful recanalization was carried out in forty hepatic veins in 40 patients. PTA of occlusive veins was followed by stent implantation in 8 patients. The pressure of hepatic veins dropped from 34.5 cm H 2 O (25.0-48.0 cm H 2 O) to 22.0 cm H 2 O (12.0-35.0 cm H 2 O) after intervention (T=11.50, P < 0.01). The symptoms and pathological signs improved obviously in 32 cases and improved partly in 8 cases. During the follow-up period from 1 month to 54 months (mean 27.5 months), one cases died of liver function failure at one month after intervention. The re-intervention of occlusive veins in two cases were performed and the better results were acquired again. Five cases didn't accept re-intervention. Neither recurrence of symptoms nor re-occlusion of hepatic veins was found in the other 32 patients. Conclusion: (1) Multiple and synthetical interventional methods for the occlusive hepatic veins in Budd-Chiari syndrome can be utilized. (2) The intervention of hepatic vein is mini

    Using a mesh to repair inguinal hernias is now a standard procedure that is widely accepted as superior to primary suture repair. Although a variety of meshes are available, individual meshes may have their own unattractive features. This retrospective study examines the efficacy of our originally designed D-13 prosthesis, which is used in patients with inguinal hernias. A total of 305 patients who underwent a herniorrhaphy between January 2009 and March 2011 were included in this study. The recurrent rate, chronic pain and feeling of a foreign body were examined at a 3-year follow-up. The D-13 prosthesis, made from clear polypropylene monofilament mesh, was originally designed by the first author of this study and constructed with the upper and lower pieces of polypropylene mesh having different shapes and sizes. Both pieces are linked together by a connector. The mesh is well tolerated. At a 3-year follow-up, only two patients had a foreign body sensation at the operative site, and three patients had recurrent hernias. The unique design of the D-13 prosthesis with two pieces of mesh provided encouraging long-term outcome for hernia recurrence, chronic pain and the feeling of a foreign body.

    Umbilical vein catheterization is a relatively easy procedure performed routinely on the neonate intensive care units. It provides a fast central vein access, but some complications have been described in the literature. Case Reports: We presented a case report of a premature infant (34 hbd) with extravasation of the parenteral nutrition and drugs to the liver after umbilical vein catheterization. Fever and increasing biochemical markers of infection were observed. USG revealed a heterogenic, well-limited space of 4 cm in diameter, located in the right lobe of the liver. CT excluded liver abscess. Considering neoplastic process or incorrect location of the catheter of the central vein, we performed liver biopsy. Results: Cytological and biochemical analysis of the aspirated fluid revealed extravasation of parenteral nutrition to the liver.Our case confirms the necessity of controlling a proper location of the central catheter right after its insertion and during hospitalization.

    2014-07-01

    Portal vein thrombosis in cirrhosis is a relatively common complication associated with the presence of an accompanying prothrombotic phenotype of advanced cirrhosis. The consequences of portal vein thrombosis are relevant because it can be associated with impaired hepatic function, might contraindicate hepatic transplantation and could increase morbidity in the surgical procedure. There is controversy concerning the most effective treatment of portal vein thrombosis, which is based on information that is seldom robust and whose primary objective is to achieve a return to vessel patency. Various studies have suggested that starting anticoagulation therapy early is associated with portal vein repatency more frequently than without treatment and has a low rate of complications. There are no proven data on the type of anticoagulant (low-molecular-weight heparins or dicoumarin agents) and the treatment duration. The implementation of TIPS is technically feasible in thrombosis without cavernous transformation and is associated with portal vein recanalization in a significant proportion of cases. Thrombolytic therapy does not appear to present an adequate balance between efficacy and safety; its use is therefore not supported for this indication. The proper definition of treatment for portal vein thrombosis requires properly designed studies to delimit the efficacy and safety of the various alternatives. Copyright © 2014 Elsevier España, S.L.

    Primary lower-limb lymphoedema is a chronic, progressive and debilitating condition with a difficult management, especially in advanced cases (elephantiasis). Recently, autologous lymph node transplantation (ALNT) appears to be a promising treatment for extremity lymphoedema. A case of a double ALNT for an advanced primary lower-limb lymphoedema is here reported: a contralateral inguinal lymph node flap was transferred to the knee and, in a second surgery, a thoracic lymph node flap was transplanted to the inguinal region. Clinical outcomes at 5 months postoperatively are very satisfactory with reduction in limb circumferences and improvement in skin quality and social impairment.

    Full Text Available Embryoanatomical peculiarities are responsible for low occurrence of inguinal hernias in females. Amongst them, ovarian hernias are rarer. They are commonly noticed in children. An attending surgeon commonly faces diagnostic and operative dilemmas in managing these overtly “simple-looking” clinical scenarios. Although ovarian cysts are one of the common contents of the sac, we report a case of adult incarcerated ovarian hernia who presented with a ruptured hemorrhagic ovarian cyst. This differential should be kept in mind while treating an adult female with painful inguinal swelling. As far our knowledge goes, such case with ruptured ovarian cyst presenting as an incarcerated hernia in an emergency scenario has not been reported as yet.

    Full Text Available Kidney transplantation is the best treatment choice in the end-stage renal disease. In the renal transplantation, renal vein damage or shortness which occurs during cadaveric or living donor nephrectomy causes technical difficulties for surgeons. The lack of the donors already especially cadaveric, the acquirement of the graft, gets very much importance. In this report, it is aimed to share the clinical experiment by which it seen, how anastomosis can become appropriate by using the renal vein which is damaged in the way that anastomosis cannot be done anyway by using cadaveric vena cava graft. The renal vein brought to length for anostomosis which is repaired by using cadaveric vena cava graft, is anastomosed successfully by becoming an end-to-side of the external iliac vein of the recipient. Vascular anastomoses are applied easily in technique. The time of the warm ischemia was under 2 hours and the kidney was functional in the post-operative period. Renal vein trombosis was not observed. The renal vein damage occured during cadaveric or living donor nephrectomy, can be repaired by some methods. In the kidneys in which vein requirement is done, the success rates are rather high although acute tubular necrosis and delayed function can be seen more.

    Full Text Available Background. The exact nature of learning curve of totally extraperitoneal inguinal hernia and the number required to master this technique remain controversial. Patients and Methods. We present a retrospective review of a single surgeon experience on patients who underwent totally extraperitoneal inguinal hernia repair. Results. There were 42 hernias (22 left- and 20 right-sided in 39 patients with a mean age of 48.8±15.1 years. Indirect, direct, and combined hernias were present in 18, 12, and 12 cases, respectively. The mean operative time was 55.1±22.8 minutes. Peritoneal injury occurred in 9 cases (21.4%. Conversion to open surgery was necessitated in 7 cases (16.7%. After grouping of all patients into two groups as cases between 1–21 and 22–42, it was seen that the majority of peritoneal injuries (7 out of 9, 77.8%, P=0.130 and all conversions (P=0.001 occurred in the first 21 cases. Conclusions. Learning curve of totally extraperitoneal inguinal hernia repair can be divided into two consequent steps: immediate and late. At least 20 operations are required for gaining anatomical knowledge and surgical pitfalls based on the ability to perform this operation without conversion during immediate phase.

    Because inguinal hernia repair is difficult for third-year students to comprehend, a 2-dimensional paper-cut was developed to teach the concepts of inguinal hernia in a time-effective manner before students' observation of herniorrhaphy in the operating room. Using Adobe Illustrator 5.5 for MacIntosh, a 2-dimensional inexpensively printed paper-cut was created to allow students to perform their own simulated hernia repair before observing surgery. The exercise was performed using a no.15 scalpel or an iris scissors and was evaluated by comparing 10-question pre-tests and post-tests. Seventy-five students performed the exercise, most completing it within 15 minutes. The mean pre-test score was 7.4/10 and the mean post-test score was 9.1/10. Students performing the paper-cut reported better understanding when observing actual herniorrhaphy. A 2-dimensional paper-cut ("surgical origami") may be a time-effective method to prepare students for the observation of hernia repair.

    In patients with portal hypertension, the blood flow volume is maintained despite decreased blood flow velocity due to enlargement of the vascular cross sectional area. Thus, the 'congestion index' of the portal vein, which is the ratio between the cross sectional area (cm2) and the blood flow velocity (cm/sec) determined by a Doppler ultrasonography, may be a sensitive index by which to assess portal hypertension. We performed Doppler ultrasonography on 24 normal subjects, 14 patients with biopsy proved chronic active hepatitis and 55 patients with liver cirrhosis in order to assess the diagnostic value of the congestion index. The cross sectional area of the portal vein was significantly enlarged and the mean blood flow velocity was significantly reduced in patients with liver cirrhosis compared with controls. However, the blood flow volume was no difference. The congestion index of the portal vein was significantly increased in patients with liver cirrhosis (0.113+0.035) compared with patients with chronic active hepatitis(0.078+0.029) (p<0.001) and controls (0.053+0.016) (p<0.001). The sensitivity, specificity and predictability of the congestion index for detection of patients with the cirrhosis of the liver were 76.4%, 100% and 100% respectively, when the normal range was set at mean+2SD. The results suggest that the congestion index of the portal vein may pla a significant role in diagnosis of portal hypertensive patients

    The vortex vein system is the drainage pathway for the choroidal circulation and serves an important function in the effective drainage of the exceptionally high blood flow from the choroidal circulation. As there are only 4-6 vortex veins, a large volume of blood must be drained from many choroidal veins into each individual vortex vein. The vortex vein system must also cope with passing through tissues of different rigidity and significant pressure gradient as it transverses from the intrao-cular to the extra-ocular compartments. However, little is known about how the vortex vein system works under such complex situations in both physiological and pathological condition. Endothelial cells play a vital role in other vascular systems, but they have not been studied in detail in the vortex vein system. The purpose of this study is to characterise the intracellular structures and morphology in both the intra-and extra-ocular regions of the human vortex vein system. We hypothesise the presence of endothelial phenotypic heterogeneity through the vortex vein system. The inferior temporal vortex vein system from human donor eyes were obtained and studied histologically using confocal microscopy. The f-actin cytoskeleton and nuclei were labelled using Alexa Fluor conjugated Phalloidin and YO-PRO-1. Eight regions of the vortex vein system were examined with the venous endothelium studied in detail with quantitative data obtained for endothelial cell and nuclei size and shape. Significant endothelial phenotypic heterogeneity was found throughout the vortex vein system with the most obvious differences observed between the ampulla and its downstream regions. Variation in the distribution pattern of smooth muscle cells, in particular the absence of smooth muscle cells around the ampulla, was noted. Our results suggest the presence of significantly different haemodynamic forces in different regions of the vortex vein system and indicate that the vortex vein system may play

    Finger vein recognition is a promising biometric recognition technology, which verifies identities via the vein patterns in the fingers. Binary pattern based methods were thoroughly studied in order to cope with the difficulties of extracting the blood vessel network. However, current binary pattern based finger vein matching methods treat every bit of feature codes derived from different image of various individuals as equally important and assign the same weight value to them. In this paper, we propose a finger vein recognition method based on personalized weight maps (PWMs). The different bits have different weight values according to their stabilities in a certain number of training samples from an individual. Firstly we present the concept of PWM, and then propose the finger vein recognition framework, which mainly consists of preprocessing, feature extraction, and matching. Finally, we design extensive experiments to evaluate the effectiveness of our proposal. Experimental results show that PWM achieves not only better performance, but also high robustness and reliability. In addition, PWM can be used as a general framework for binary pattern based recognition. PMID:24025556

Binary pattern based methods were thoroughly studied in order to cope with the difficulties of extracting the blood vessel network. However, current binary pattern based finger vein matching methods treat every bit of feature codes derived from different image of various individuals as equally important and assign the same weight value to them. In this paper, we propose a finger vein recognition method based on personalized weight maps (PWMs. The different bits have different weight values according to their stabilities in a certain number of training samples from an individual. Firstly we present the concept of PWM, and then propose the finger vein recognition framework, which mainly consists of preprocessing, feature extraction, and matching. Finally, we design extensive experiments to evaluate the effectiveness of our proposal. Experimental results show that PWM achieves not only better performance, but also high robustness and reliability. In addition, PWM can be used as a general framework for binary pattern based recognition.

    Previous animal models of venous disease, while inducing venous hypertension and valvular insufficiency, do not produce superficial varicose veins. In this study, we aimed to develop and characterize a pig-based model of superficial varicose veins. Right femoral arteriovenous fistulae (AVF) were surgically fashioned in young adult pigs. Animals were examined at postoperative times up to 15 weeks to determine the development of varicose veins and measurement of both blood pressure and flow velocities within the superficial thigh veins. Histology and vascular corrosion casts were used to characterize the resulting structural venous alterations. Porcine pathophysiological features were compared with those of human primary superficial varicose veins. Gross superficial varicosities developed over the ipsilateral medial thigh region after an initial lag period of 1-2 weeks. Veins demonstrated retrograde filling with valvular incompetence, and a moderate, non-pulsatile, venous hypertension, which was altered by changes in posture and Valsalva. Venous blood flow velocities were elevated to 15-30 cm/s in varicose veins. Structurally, pig varicose veins were enlarged, tortuous, had valvular degeneration, and regions of focal medial atrophy with or without overlying intimal thickening. The superficial varicose veins, which developed within this model, have a pathophysiology that is consistent with that observed in humans. The porcine femoral AVF model is proposed as a suitable experimental model to evaluate the pathobiology of superficial venous disease. It may also be suitable for the evaluation of treatment interventions including drug therapy.

    Liver transplantation in patients with liver cirrhosis, portal vein thrombosis, and cavernous transformation of the portal vein, is a complex procedure with high possibility of liver graft dysfunction. It is performed in 2-19% of all liver transplants, and has a significantly high mortality rate in the post-operative period. Other procedures to maintain portal perfusion have been described, however there are no reports of liver graft perfusion using right gastroepiploic vein. A 20 year-old female diagnosed with cryptogenic cirrhosis, with a Child-Pugh score of 7 points (class "B"), and MELD score of 14 points, with thrombosis and cavernous transformation of the portal vein, severe portal hypertension, splenomegaly, a history of upper gastrointestinal bleeding due to oesophageal varices, and left renal agenesis. The preoperative evaluation for liver transplantation was completed, and the right gastroepiploic vein of 1-cm diameter was observed draining to the infrahepatic inferior vena cava and right suprarenal vein. An orthotopic liver transplantation was performed from a non-living donor (deceased on January 30, 2005) using the Piggy-Back technique. Portal vein perfusion was maintained using the right gastroepiploic vein, and the outcome was satisfactory. The patient was discharged 13 days after surgery. Liver transplantation was performed satisfactorily, obtaining an acceptable outcome. In this case, the portal perfusion had adequate blood flow through the right gastroepiploic vein.

    Aims: In images of magnetic resonance and computed tomography (CT) there are visible angles between pulmonary veins and the coronary, transversal or sagittal section of body. In this study these angles are measured and defined as Projective Angles of pulmonary veins. Several possible influential factors and characters of distribution are studied and analyzed for a better understanding of this imaging anatomic character of pulmonary veins. And it could be the anatomic base of adjusting correctly the angle of the central X-ray of the angiography of pulmonary veins undergoing the catheter ablation of atrial fibrillation (AF). Method: Images of contrast enhanced magnetic resonance angiography (CEMRA) and contrast enhanced computer tomography (CECT) of the left atrium and pulmonary veins of 137 health objects and patients with atrial fibrillation (AF) are processed with the technique of post-processing, and Projective Angles to the coronary and transversal sections are measured and analyzed statistically. Result: Project Angles of pulmonary veins are one of real and steady imaging anatomic characteristics of pulmonary veins. The statistical distribution of variables is relatively concentrated, with a fairly good representation of average value. It is possible to improve the angle of the central X-ray according to the average value in the selective angiography of pulmonary veins undergoing the catheter ablation of AF.

    Twenty post-mortem specimens and 93 phlebographies (56 right side, 37 left side) from 44 patients were investigated with respect to the adrenal venous anatomy. At autopsy, the venous orifices displayed in the area of adrenal drainage were injected bilaterally to identify the adrenal vein(s), the surrounding channels and the presence of interconnections. The findings were correlated with those at clinical phlebography, and the different sources of error were elicited. These were mainly found on the right side. Some guidelines are suggested in the hope that these will contribute to eliminate misconceptions.

    A critical review is presented of published data bearing on the mineralogy, paragenesis, geochemistry, and origin of veiw-type uranium deposits. Its aim is to serve as a starting point for new research and as a basis for the development of new exploration strategies. During the formation of both vein and sandstone types of deposits uranium seems to have been dissolved by and transported in rather oxidized solutions, and deposited where these solutions encountered reducing agents such as carbon, sulfides, ferrous minerals and hydrocarbons. Granitic rocks abnormally enriched in uranium have apparently been the most common source for uranium in vein-type deposits. Oxidizing solutions have been derived either from the surface or from depth. Surface solutions saturated with atmospheric oxygen have frequently passed through red bed or clean sandstone conduits on their way to and from uranium source rocks. Deep solutions of non-surface origin have apparently become sufficiently oxidizing by passage through and equilibration with red beds. The common association of clean sandstones or red beds with uranium-rich granites in the vicinity of vein-type uranium deposits is probably not fortuitous, and areas where these rock types are found together are considered particularly favorable targets for uranium exploration

  2. Interposition vein cuffs.

    1996-01-01

    A vein cuff interposed at the distal anastomosis between a prosthetic vascular graft and a recipient infrageniculate artery improves the chances of continued patency of the graft, at least in the short and medium term. The mode of effect appears to be suppression or modification of anastomotic myointimal hyperplasia (MIH). In the event of graft failure the recipient artery and run-off vessels remain free from MIH and their patency is preserved thereby improving the prospects for further vascular reconstruction and limb salvage. The mechanisms by which interposition vein cuffs might modulate MIH are reviewed. Experimental evidence is described to show that the geometry of a cuffed anastomosis promotes a characteristic haemodynamic flow structure with a stable vortex. It is suggested that this vortex exerts greater shear stress upon the wall of the artery than the normal laminar flow observed in conventional anastomoses. High shear stress is known to inhibit MIH.

    The issue of mesh fixation in endoscopic inguinal hernia repair is frequently debated and still no conclusive data exist on differences between methods regarding long-term outcome and postoperative complications. The quantity of trials and the simultaneous lack of high-quality evidence raise the question how future trials should be planned. PubMed, EMBASE and the Cochrane Library were searched, using the filters "randomised clinical trials" and "humans". Trials that compared one method of mesh fixation with another fixation method or with non-fixation in endoscopic inguinal hernia repair were eligible. To be included, the trial was required to have assessed at least one of the following primary outcome parameters: recurrence; surgical site infection; chronic pain; or quality-of-life. Fourteen trials assessing 2161 patients and 2562 hernia repairs were included. Only two trials were rated as low risk for bias. Eight trials evaluated recurrence or surgical site infection; none of these could show significant differences between methods of fixation. Two of 11 trials assessing chronic pain described significant differences between methods of fixation. One of two trials evaluating quality-of-life showed significant differences between fixation methods in certain functions. High-quality evidence for differences between the assessed mesh fixation techniques is still lacking. From a socioeconomic and ethical point of view, it is necessary that future trials will be properly designed. As small- and medium-sized single-centre trials have proven unable to find answers, register studies or multi-centre studies with an evident focus on methodology and study design are needed in order to answer questions about mesh fixation in inguinal hernia repair.

    A better understanding of the analgesia needs of patients who undergo common operative procedures is necessary as we address the growing opioid public health crisis in the United States. The aim of this study was to evaluate patient experience with our opioid prescribing practice after elective inguinal hernia repairs. A prospective, observational study was conducted between October 1, 2015, and September 30, 2016, in a single-surgeon, high-volume, practice of inguinal hernia operation. Adult patients undergoing elective inguinal herniorrhaphy under local anesthesia with intravenous sedation were invited to participate. All patients were prescribed 10 opioid analgesic tablets postoperatively and were counseled to reserve opioids for pain not controlled by nonopioid analgesics. Their experience was captured by completing a questionnaire 2 to 3 weeks postoperatively during their postoperative visit. A total of 185 patients were surveyed. The majority of the participants were males (177, 95.7%) and ≥60 years old (96, 51.9%). Of the 185 patients, 159 (85.9%) reported using ≤4 opioid tablets; 110 patients (59.5%) reported that they used no opioid analgesics postoperatively. None of the patients was taking opioids within 7 days of their postoperative appointment. Of the 147 patients who were employed, 111 (75.5%) reported missing ≤3 work days, 57 of whom (51.4%) missed no work at all. Patients who were employed were more likely to take opioid analgesics postoperatively (P = .049). Patients who took no opioid analgesics experienced less maximum (P require any opioid analgesics, and nearly all of those who thought that they did need opioids used reserved.

    Full Text Available Background: Demonstration of central: Peripheral adrenocorticotropic hormone (ACTH gradient is important for diagnosis of Cushing′s disease. Aim: The aim was to assess the utility of internal jugular vein (IJV: Peripheral vein ACTH ratio for diagnosis of Cushing′s disease. Materials and Methods: Patients with ACTH-dependent Cushing′s syndrome (CS patients were the subjects for this study. One blood sample each was collected from right and left IJV following intravenous hCRH at 3 and 5 min, respectively. A simultaneous peripheral vein sample was also collected with each IJV sample for calculation of IJV: Peripheral vein ACTH ratio. IJV sample collection was done under ultrasound guidance. ACTH was assayed using electrochemiluminescence immunoassay (ECLIA. Results: Thirty-two patients participated in this study. The IJV: Peripheral vein ACTH ratio ranged from 1.07 to 6.99 ( n = 32. It was more than 1.6 in 23 patients. Cushing′s disease could be confirmed in 20 of the 23 cases with IJV: Peripheral vein ratio more than 1.6. Four patients with Cushing′s disease and 2 patients with ectopic ACTH syndrome had IJV: Peripheral vein ACTH ratio less than 1.6. Six cases with unknown ACTH source were excluded for calculation of sensitivity and specificity of the test. Conclusion: IJV: Peripheral vein ACTH ratio calculated from a single sample from each IJV obtained after hCRH had 83% sensitivity and 100% specificity for diagnosis of CD.

    Conventional finger-vein recognition systems perform recognition based on the finger-vein lines extracted from the input images or image enhancement, and texture feature extraction from the finger-vein images. In these cases, however, the inaccurate detection of finger-vein lines lowers the recognition accuracy. In the case of texture feature extraction, the developer must experimentally decide on a form of the optimal filter for extraction considering the characteristics of the image database. To address this problem, this research proposes a finger-vein recognition method that is robust to various database types and environmental changes based on the convolutional neural network (CNN). In the experiments using the two finger-vein databases constructed in this research and the SDUMLA-HMT finger-vein database, which is an open database, the method proposed in this research showed a better performance compared to the conventional methods.

    The authors report on a fatal mesenteric vein thrombosis following an uncomplicated percutaneous transhepatic portal vein catheterisation for the localisation of an insulinoma. Several hours after the procedure the patient developed an acute abdomen. An emergency laparotomy revealed a haemorrhagic infarct of the ileum. The resected specimen showed an acute phlebitis with fresh thrombus. The cause of the phlebothrombosis was thought to be intimal damage from high osmolar contrast medium. There was no evidence of damage due to the catheder, either on the phlebogram or pathologically. (orig.) [de

    To report the visual acuity response after intravitreal triamcinolone injection in patients with macular edema due to retinal vein occlusions. Retrospective nonrandomized interventional series of 172 consecutive patients with macular edema due to retinal vein occlusions who were treated with intravitreal triamcinolone acetonide injection. Patients underwent Snellen visual acuity testing and ophthalmoscopic examination at baseline and 1, 3, 6, and 12 months after intravitreal triamcinolone acetonide injection. All subtypes of retinal vein occlusions showed significant improvements in mean visual acuity 1 month after injection. This improvement in visual acuity was maintained over the 12-month period for all but the central retinal vein occlusion group. Seventy-one (41.3%) of the 172 patients received more than one intravitreal triamcinolone injection for unresolved or recurrent macular edema. This study demonstrates a benefit associated with intravitreal triamcinolone acetonide injection for retinal vein occlusions that was maintained by patients with branch retinal vein occlusions and hemiretinal vein occlusions over a 12-month period. Visual acuity improvement was not maintained in patients with central retinal vein occlusions with this course of treatment.

    Finger veins have been proved to be an effective biometric for personal identification in the recent years. However, finger vein images are easily affected by influences such as image translation, orientation, scale, scattering, finger structure, complicated background, uneven illumination, and collection posture. All these factors may contribute to inaccurate region of interest (ROI) definition, and so degrade the performance of finger vein identification system. To improve this problem, in this paper, we propose a finger vein ROI localization method that has high effectiveness and robustness against the above factors. The proposed method consists of a set of steps to localize ROIs accurately, namely segmentation, orientation correction, and ROI detection. Accurate finger region segmentation and correct calculated orientation can support each other to produce higher accuracy in localizing ROIs. Extensive experiments have been performed on the finger vein image database, MMCBNU_6000, to verify the robustness of the proposed method. The proposed method shows the segmentation accuracy of 100%. Furthermore, the average processing time of the proposed method is 22 ms for an acquired image, which satisfies the criterion of a real-time finger vein identification system.

    Full Text Available Contact-free palm-vein recognition is one of the most challenging and promising areas in hand biometrics. In view of the existing problems in contact-free palm-vein imaging, including projection transformation, uneven illumination and difficulty in extracting exact ROIs, this paper presents a novel recognition approach for contact-free palm-vein recognition that performs feature extraction and matching on all vein textures distributed over the palm surface, including finger veins and palm veins, to minimize the loss of feature information. First, a hierarchical enhancement algorithm, which combines a DOG filter and histogram equalization, is adopted to alleviate uneven illumination and to highlight vein textures. Second, RootSIFT, a more stable local invariant feature extraction method in comparison to SIFT, is adopted to overcome the projection transformation in contact-free mode. Subsequently, a novel hierarchical mismatching removal algorithm based on neighborhood searching and LBP histograms is adopted to improve the accuracy of feature matching. Finally, we rigorously evaluated the proposed approach using two different databases and obtained 0.996% and 3.112% Equal Error Rates (EERs, respectively, which demonstrate the effectiveness of the proposed approach.
