Inguinal Canal (inguinal + canal)
Selected AbstractsStanding laparoscopic herniorrhaphy in stallions using cylindrical polypropylene mesh prosthesisEQUINE VETERINARY JOURNAL, Issue 1 2001T. MARIËN Summary Standing laparoscopic herniorrhaphy was performed in 9 stallions. Appropriate analgesia was achieved by sedation with detomidine and local flank infiltration with mepivacaine. Three portal sites at the paralumbar fossa were used to perform the herniorrhaphy by means of triangulation. A cylindrical polypropylene mesh was inserted and fixated in the inguinal canal. Subsequent adhesion formation resulted in an obliterated inguinal canal within 2 weeks. This minimal invasive technique allowed us to perform a testis sparing herniorrhaphy in the standing horse. [source] Inguinal hernia of seminal vesicle cystINTERNATIONAL JOURNAL OF UROLOGY, Issue 11 2004KATSUKI INOUE Abstract Seminal vesicle cysts are uncommon abnormalities in the pelvis. The case of a seminal vesicle cyst that extended through the inguinal canal is reported. A 35-year-old man presented with left inguinal swelling. He was diagnosed with a left inguinal hernia. However, the interpretative diagnosis was a spermatic cord tumor. The operation was changed to tumor resection. The tumor existed along with the vas deferens from part of the parietal peritoneum outside the inguinal tunnel to the deep pelvic space. The cylinder-shaped tumor was 3 cm in diameter and 20 cm long. Pathological examination revealed a seminal vesicle cyst that extended through the inguinal canal. To the best of our knowledge, this is the first case report of a seminal vesicle cyst inguinal hernia. [source] Intra-abdominal testis with loop-like epididymis and intra-canalicular vas and vesselsINTERNATIONAL JOURNAL OF UROLOGY, Issue 9 2002AHMED ANWAR Abstract A case of intra-abdominal testis with loop-like epididymis and intra-canalicular vas and vessels is presented. A 3-year-old male with left impalpable testis since birth was admitted to our department. Physical examination and ultrasonography were inconclusive. Laparoscopy revealed a small left abdominal testis with surrounding adhesions close to the left-obliterated umbilical artery. The vas deferens and spermatic vessels were entering into the internal inguinal ring. The processus vaginalis was patent. At inguinal exploration the testis was atrophic and the epididymis was loop-like, joining the vas deferens in the inguinal canal. The spermatic vessels continued to the atrophic testis in a loop-like manner. The testis, epididymis and the vas deferens were removed. Histopathological examination of the testis revealed Sertoli cells only. If inguinal exploration had been performed without laparoscopy, the presence of the vas deferens and spermatic vessels in the inguinal canal with the absence of the testis could have been misdiagnosed as vanishing testis. Abdominal testis would thus have been missed, with increased risk of complications, particularly malignancy. [source] Measurement of the linear dynamics of the descent of the bovine fetal testisJOURNAL OF ANATOMY, Issue 1 2003M. J. Edwards Abstract Measurements were made on 86 male bovine fetuses collected from abattoirs in the vicinity of Sydney, Australia. The fetal body length was used to calculate the approximate day of gestational age (DGA); most fetuses were between 60 and 150 DGA. The distances from the caudal pole of the kidney (metanephros) to, respectively, the tip of the scrotum, the distal end of the testis and the internal ring of the inguinal canal were measured, as well as the dimensions of the testis and gubernaculum testis. Distances of (1) testis to inguinal canal, (2) inguinal canal to scrotum, (3) testis to scrotum and (4) gubernaculum to scrotum were calculated from these measurements, which were made on both left and right sides. The total length of the gubernaculum testis increased during transabdominal passage and during transinguinal passage of the testis. Furthermore, the gubernaculum appeared to maintain the testis at a relatively fixed distance from the scrotum during transabdominal passage so that the inguinal canal appeared to move towards the testis. The greatest distance between the testis and the tip of the scrotum was found during the transinguinal passage of the testis and was 2.8 cm for the left testis and 2.3 cm for the right. When located within the scrotum, each testis was still 1.6,1.7 cm from the tip of the scrotum, so the distance to be traversed was only 0.6,1.2 cm. Following passage of the testis through the inguinal canal, the gubernaculum became shorter and its distal tip was displaced toward the distal end of the scrotum. Traction by the gubernaculum could account for the final transposition of the testis from the external inguinal ring to the scrotum. Other factors involved in displacement of the testis include differential growth patterns as well as increases in the dimensions of the testis itself. [source] Does the presence of a mesh have an effect on the testicular blood flow after surgical repair of indirect inguinal hernia?JOURNAL OF CLINICAL ULTRASOUND, Issue 2 2009Selma Uysal Ramadan MD Abstract Purpose. Modern treatment of inguinal hernias includes prosthetic mesh repairs. However, direct contact of the mesh to the vessels in the inguinal canal and perimesh fibrosis may have a negative impact on testicular flow. The aim of this prospective study was to evaluate the effect of mesh implantation/perimesh fibrosis on testicular flow after repair of indirect inguinal hernias (IIHs). Method. Forty-eight male patients with unilateral IIH were included. Both testicular parenchyma were assessed using gray-scale sonography, and color/spectral Doppler sonography was performed to evaluate testicular arterial impedance, perfusion, and venous flow. Measurements were made bilaterally at the level of the inguinal canal 1 day before and at the end of the 2nd month after the operation. Results. There was no difference in testicular and echotexture perfusion between the hernia and the control sides pre- and postoperatively. No venous thrombosis was found. In all groups, resistance index and pulsatility index, measured at 4 levels, were highest in the proximal inguinal canal and lowest at the extratesticular,intrascrotal level (p < 0.05). For all Doppler parameters there was no significant difference between the pre- and postoperative measurements on both the hernia and the control sides. Conclusion. Mesh implantation/perimesh fibrosis does not adversely affect ipsilateral testicular flow. Mesh application is still a safe procedure in male patients in whom testicular function is important. © 2008 Wiley Periodicals, Inc. J Clin Ultrasound, 2009 [source] Pyometra with inguinal herniation of the left uterine horn and omentum in a Beagle dogJOURNAL OF VETERINARY EMERGENCY AND CRITICAL CARE, Issue 1 2007Christopher G. Byers DVM Abstract Objective: To describe a unique case of pyometra with inguinal herniation of the left uterine horn and omentum. Case summary: A 7-year-old, 19 kg, intact female Beagle dog presented for surgical treatment of presumptive pyometra and biopsy of a caudal abdominal mass in the left inguinal mammary gland region. Ventral midline celiotomy was performed, and a distended, fluid-filled uterus with passage of the distal aspect of the left uterine horn through the left vaginal process into the inguinal canal was identified. The patient recovered uneventfully following ovariohysterectomy and left inguinal herniorrhaphy. New or unique information provided: This is the first documented report of inguinal herniation of a uterine horn associated with a pyometra. [source] Scrotal reconstruction with a free greater omental flap: A case reportMICROSURGERY, Issue 5 2010Darren Ng M.B.B.S., M.R.C.S. We report a case of Fournier's gangrene, where we used the greater omentum as a free flap for scrotal reconstruction and outline the advantages over previously described methods. The greater omentum was harvested using a standard open technique. The deep inferior epigastric vessels were passed through the inguinal canal into the scrotal area as recipient vessels. The detached greater omental flap was prefabricated into a three-dimensional sac prior to inset and microvascular anastomoses. The flap was then covered by skin graft. The reconstruction had shown good early results with complete survival of the flap, as well as good functional and esthetic outcome at six months. The greater omentum can therefore be used as a free flap for scrotal reconstruction. It allows easy prefabrication and flap inset. The deep inferior epigastric vessels are also suitable recipient vessels. © 2010 Wiley-Liss, Inc. Microsurgery 30:410,413, 2010. [source] Vaginal Ring and Round Ligament of the Uterus in the Female CatANATOMIA, HISTOLOGIA, EMBRYOLOGIA, Issue 4 2009A. Watson Summary The peritoneum was examined for the existence of a vaginal ring and the round ligament of the uterus was dissected through the inguinal region in eleven embalmed adult female cats. In all cats, there was no evidence of a peritoneal evagination into the inguinal canal. There was no vaginal ring and no vaginal process. The round ligament of the uterus passed through the inguinal canal and disintegrated in the fascia a short distance beyond the superficial inguinal ring. [source] Position and Histological Structure of the Testes in the Brown Hare (Lepus europaeus) during Seasonal Regression and RecrudescenceANATOMIA, HISTOLOGIA, EMBRYOLOGIA, Issue 2 2000B. Simeunovi The position and histological structure of the testes of 33 brown hares (Lepus europaeus) were studied from July to December. From July to September, the testes were located in the scrotum; in October and November, in some animals, the testes were positioned more or less in the inguinal canal towards the abdominal cavity, and in December none of the investigated animals had testes located in the scrotum. Testes were weighed and a quantitative analysis of tissue components was performed: the diameter of the seminiferous tubules, the depth of the seminiferous epithelium, the thickness of the tunica albuginea, the thickness of the peritubular tissue and the relative proportion of seminiferous tubules were determined. The tunica albuginea and peritubular tissue were thickest in September, October and at the beginning of November. In the same months the testis weight was low, and the diameter of the seminiferous tubules, the depth of the seminiferous epithelium and the relative proportion of seminiferous tubules in the testis tissue were significantly lower than in other months. We did not find any correlation between testicular regression or testis weight reduction and the change in the position of the testes. During recrudescence of spermatogenesis in November and December the testes were located in the inguinal canal. [source] Polyorchidism: a three-case report and review of the literatureANDROLOGIA, Issue 1 2010M. Savas Summary The presence of more than two testes confirmed by histology is called polyorchidism. Polyorchidism is an extremely rare congenital anomaly with a few more than 100 cases reported in the literature. The majority of reported cases are asymptomatic patients, others present with cryptorchidism, hydrocele, varicocele, epididymitis, infertility, testicular malignancy and testicular torsion. Over a 2-year period, we encountered three patients who were found to have polyorchidism; two men presented with cryptorchidism and one with chronic scrotal pain. Physical examination of the first and the third patient revealed normal testes in the scrotal sac, the other scrotal sac was empty and small solid mass (atrophic left testes) was palpated in the inguinal canal. Ultrasonographic examination of the scrotum and inguinal region confirmed the findings of the physical examination. Ultrasonographic examination of the second patient revealed supernumerary testes within the scrotum. Orchiectomy was made on the first and third patients' supernumerary testes and ipsilateral inguinal high ligation was applied for herniorrhaphy. A conservative approach was preferred for the second patient, maybe preserving a potentially functional supernumerary testis to improve the capacity for spermatogenesis. The risk of malignancy justifies the removal of an atrophic and ectopic testis in polyorchidism. However, it would appear safe to preserve a viable intrascrotal supernumerary testis found incidentally at surgery, provided that the patient is followed-up in the long term. [source] Fetal development of the human gubernaculum with special reference to the fasciae and muscles around itCLINICAL ANATOMY, Issue 6 2008Hitoshi Niikura Abstract Previous descriptions of human gubernacular embryology failed to follow some basic developmental processes, and surgically relevant structures, such as the iliopubic tract, had not been discussed relative to gubernacular development. We addressed these shortcomings in this study that examined two stage-groups of human fetuses. At 8,12 weeks of gestation, the gubernaculum arose from the mesonephric fold at or near the gonad. Gubernacular mesenchyme communicated with the subcutaneous tissue via a narrow slit in the rectus aponeurosis. The inguinal fold, containing the inferior epigastric vessels, was separated from the gubernaculum. At 20,25 weeks of gestation, the gubernaculum connected to the testis or uterus. When the testis successfully descended to a peritoneal recess on the lateral side of the umbilical artery, the gubernaculum connected to the testis free of interference by the thick artery and its associated peritoneal fold. This may explain the known asymmetry in testicular descent. The inguinal canal was enclosed by a sheet-like aponeurosis: its ventromedial part was composed of the rectus sheath and the external oblique aponeurosis, whereas the dorsolateral part consisted of a thick aponeurosis covering or facing the iliopsoas. The former (latter) aponeurosis seemed to develop into the inguinal ligament (the iliopubic tract) in adults. According to the topohistology of the muscles associated with the interfoveolar ligament, we identified muscle fragments around the gubernaculum as derivatives of the transversus and/or internal oblique. Consequently, the inguinal canal contained the cremaster proper developing within the gubernaculum and parts of the abdominal wall muscles mechanically incorporated into the canal. Clin.

Bülent Özdemir Abstract An unusual course of the right testicular artery was observed during routine dissection of the posterior abdominal wall of a 60-year-old male cadaver. It arose from the abdominal aorta, inferior and posterior to the origin of the right renal artery, and passed posterior to the inferior vena cava and right renal vein; it then arched anterior to the inferior pole of the right kidney and descended anterior to the psoas major muscle, crossing anterior to the genitofemoral nerve, ureter and the proximal part of the external iliac artery. Finally, it passed to the deep inguinal ring and through the inguinal canal to enter the spermatic cord with the other constituents. The left testicular artery arose from the abdominal aorta about 1 cm higher than the right testicular artery and followed a normal course. The embryologic basis and clinical importance of this case are discussed. Clin. Anat. 17:67,69, 2004. © 2003 Wiley-Liss, Inc. [source] | |||||||||||||
