Perforated appendicitis within an inguinal hernia: case report and review of the literature

The finding of the vermiform appendix within an inguinal hernia sac is not uncommon. However, it is rare to find a perforated appendix within an inguinal hernia. An unusual case of an incarcerated and perforated appendix within an inguinal hernia complicated by an intra-abdominal abscess is reported herein. Perforated appendix as a cause of abscess was revealed during abdominal exploration. Clinicians are encouraged to be aware of this unusual entity, which is rarely recognized before exploration.     

Dacryocystitis associated with malignant lymphoma of the lacrimal sac

BACKGROUND: Tumors of the lacrimal sac are unusual, and lymphomas of the lacrimal sac are quite rare. Four patients with a history of well-differentiated, small cell lymphoma or chronic lymphocytic leukemia presented with either acute or chronic dacryocystitis and epiphora due to lymphomatous infiltration of the lacrimal sac. METHODS: All four patients underwent dacryocystorhinostomy with lacrimal sac biopsy. All tissues underwent complete histopathologic evaluation including immunohistochemical studies for cell surface markers and, in addition, were compared with previous biopsies performed for the initial diagnosis of lymphoma. FINDINGS: All biopsies demonstrated small cell well-differentiated lymphoma on histologic and immunofluorescent examination. No patient demonstrated orbital involvement on computed tomography. One patient had previously diagnosed chronic lymphocytic leukemia and one patient demonstrated diffuse lymph node involvement on postoperative systemic evaluation. All four patients underwent additional chemotherapy. No recurrence of dacryocystitis or epiphora occurred. CONCLUSION: Four patients presented with dacryocystitis secondary to lacrimal sac lymphoma. Lymphomatous lacrimal sac infiltration is an unusual cause of dacryocystitis. Biopsy of the lacrimal sac plays a diagnostically important role in dacryocystorhinostomy even in the absence of obvious tumorous involvement of the lacrimal sac mucosa.     

The pathological evaluation of the pediatric inguinal hernia sac

BACKGROUND: The College of American Pathologists has suggested that institutions should establish guidelines for the evaluation of the hernia sac. In addition, some states require the submission of this tissue for pathological evaluation. Yet, neither evidence-based guidelines nor published reviews for the evaluation of the pediatric hernia sac are available. Therefore, this retrospective study was conducted to document experience with the evaluation of the pediatric hernia sac. METHODS: All reports of the evaluation of hernia sacs submitted to the Department of Pathology during an 8-year period were reviewed. The case of any report that differed in any way from "consistent with hernia sac" was evaluated for the effect of the findings on the clinical course. RESULTS: A total of 7,924 hernia sacs were submitted on 6,034 patients. Microscopic evaluation was performed on 534. A total of 7,567 (95.4%) submitted specimens on 5,743 patients were "consistent with hernia sac" and demonstrated no other findings. Three hundred fifty-seven specimens contained findings in addition to hernia sac. In no patient did the results of the evaluation have an effect on the patient care. CONCLUSIONS: There is strong evidence that the routine pathological evaluation of pediatric hernia sacs offers little relevant clinical information. Mandatory tissue submission of hernia sacs should be reconsidered.     

The silent epidural abscess as a complication of acute otitis media in children

Vesical hernia is defines as a vesical shift associated to a direct or indirect inguinal hernia. It accounts for 0.4-3% of all inguinal hernias, but the existence of a massive vesical hernia formation at the inguinoscrotal level is uncommon; a total of 114 cases have been found in the literature. Clinically it should be suspected every time an inguinoscrotal hernia is found in patients over 50 years old with urinary flow obstruction. Diagnosis is usually reached through serial voiding cystouretrography (SVCU). The preferred treatment should be extraperitoneal inguinal herniorrhaphy associated to correction of the obstructive process.     

Management of impalpable testes: indications for abdominal exploration

Various approaches to the management of the impalpable testis in cases of cryptorchidism have been advocated. The authors' experience over the past 13 years was reviewed to try to determine an optimal approach. Of 1,305 patients with undescended testicles seen between February 1982 and December 1995, 157 boys (12.03%) had impalpable testes with 17 having bilateral impalpable testes for a total of 174 impalpable testes. A hernia sac was present in 155 impalpable testes with a testicle present in all cases. No hernia sac was found in 19 impalpable testes, five of which had no testicle present. This was confirmed by either open exploration or laparoscopy. One hundred forty-eight boys underwent groin exploration as initial treatment, 13 of these had bilateral impalpable testes. In addition to the five absent testicles with no hernia sac, one patient with a hernia sac and no testicle evident benefited from subsequent laparoscopy to identify an intraabdominal testicle. All other patients underwent routine orchidopexy or orchidectomy (one case with grossly malformed testicle). Nine boys underwent laparoscopy as initial treatment, four of these had bilateral impalpable testes. Two abnormal testicles were found and removed. Groin exploration and subsequent orchidopexy was definitive treatment in all other cases. The association of a hernia sac with an impalpable undescended testicle is very significant (P < .00001 Fisher's Exact test). The absence of a sac therefore may reflect an alternate diagnosis. When no sac is found with a testicle in the groin, this may represent an ectopic testicle. When no sac is found with no testicle, this may represent a vanishing testicle. From this experience the authors conclude that groin exploration should be the initial approach to impalpable testes. The presence of a hernia sac with an absent testicle demands further exploration; the absence of a hernia sac with an absent testicle suggests a vanishing testicle and may need no further exploration.     

Incarcerated scrotal hernia containing a sigmoid colon carcinoma

The authors describe the case-history of a 65-year-old patient with an incarcerated scrotal hernia on the left side. An unexpected finding in the sac of the scrotal hernia was the sigmoid colon with an obturating tumour. The patient was subjected to two-stage surgery with a favourable final effect.     

Standard versus individually planned irradiation field in radiotherapy of infradiaphragmatic lymph node sites]

PURPOSE: The aim of this study was to determine the utility of scrotal sonography in the evaluation of patients with scrotal pain or swelling following inguinal hernia repair. METHODS: From our database, we identified patients who were referred for sonographic evaluation because of persistent scrotal pain or swelling after inguinal hernia repair between July 1994 and February 1996. Sonograms and medical charts were reviewed retrospectively. RESULTS: Eight patients were included in this study. Doppler sonography demonstrated evidence of testicular infarction in 2 patients and absence of intratesticular diastolic flow in 1 patient. Five patients had postoperative fluid collections with sonographically normal testes. CONCLUSIONS: Scrotal sonography can diagnose testicular infarction following hernia repair and distinguish postoperative fluid collections from recurrent hernias.     

Increase in endogenous thrombopoietin in healthy donors after automated plateletpheresis

Inguinoscrotal bladder hernias are uncommon clinical facts more predominant in males aged between 50 and 70. This entity has no specific clinical character and diagnosis usually happens in the course of surgical repair of inguinal hernia. In about 3%-10% cases, it appears associated to inguinal hernia. Discussion of two case-reports of patients with giant inguinoscrotal bladder hernia; one patient with synchronous association to bladder transitional carcinoma. The literature on the clinical, diagnostic and therapeutic aspects is revised. The high index of suspicion for making a pre-operative diagnosis, specially in aged patients with inguinal hernia and expanded prostate signs and symptoms is highlighted. Emphasis is placed on the need for surgical hernia repair prior to prostate and/or bladder transurethral surgery.     

Endoscopically guided percutaneous repair of inguinal hernia through a 2-cm incision. Minihernia repair

BACKGROUND: The laparoscopic repair of inguinal hernia is still controversial. Transabdominal preperitoneal repair violates the peritoneal cavity and may result in visceral injuries or intestinal obstruction. The laparoscopic extraperitoneal approach has the disadvantage of being technically demanding and requires extensive extraperitoneal mobilization. The Lichtenstein repair gives good long-term results, is easy to learn, can be performed under local anesthesia, but requires a larger incision. METHODS: We describe a novel percutaneous tension-free prosthetic mesh repair performed through a 2-cm groin incision. The inguinal canal is traversed with the aid of a 5-mm video-endoscope and the canal is widened using specially designed balloons. Spermatic cord mobilization, identification and excision of the indirect sac, and posterior wall repair are carried out under endoscopic guidance. RESULTS: Between October 1993 and July 1995, 85 primary inguinal hernia repairs (48 indirect and 33 direct) were performed on 81 patients (80 men, one woman) by the author (A.D.). The mean age was 41 years (range 17-83 years). Six repairs were performed under local anesthetic. Mean operative time was 42 min (range 25-74). Mean hospital stay was 1.2 days (0-3 days). The mean return to normal activity was 8 days (2-10 days). Eight complications have occurred: a serous wound discharge, two scrotal hematomas, a scrotal swelling that resolved spontaneously, wound pain lasting 2 weeks, an episode of urinary retention, and two recurrences early in the series (follow-up 1-22 months). CONCLUSION: The endoscopically guided percutaneous hernia repair avoids the disadvantages of laparoscopy (i.e., lack of stereoscopic vision, reduced tactile feedback, unfamiliar anatomical approach, risk of visceral injury), yet the use of endoscopic instrumentation allows operation through a 2-cm incision. The minihernia repair thus combines the virtues of an open tension-free repair with minimal access trauma.     

Fetal inguinoscrotal hernia: sonographic diagnosis and obstetric management

Fetal inguinal hernia is a rare antenatal diagnosis. We present the sonographic features and outcome of a fetus diagnosed at 36 weeks' gestation as having an (indirect) inguinoscrotal hernia. Sonographic criteria for antenatal diagnosis are discussed within the context of differential diagnoses raised by the presence of a perineal mass. Guidelines for obstetric management and counselling are suggested.     

Laparoscopic evaluation for a contralateral patent processus vaginalis: part III

OBJECTIVES: Between May 1, 1992 and August 1, 1996, 759 consecutive children younger than 10 years of age were evaluated and treated for known inguinal hernia. These children were participating in a prospective investigation of the potential role of diagnostic laparoscopy in the evaluation of the contralateral inguinal anatomy. The initial two series of data (parts I and II of this three-part series) were previously presented at the 1993 and 1995 American Academy of Pediatrics meetings. METHODS: Of 759 patients, 100 children were diagnosed with bilateral inguinal hernias and therefore did not undergo laparoscopy. Thirty-two patients did not undergo laparoscopic evaluation due to technical difficulties or complicated clinical situations. The patient's contralateral inguinal region was carefully examined under anesthesia, and predictions were made regarding the likelihood of contralateral patent processus vaginalis (CPPV). Six hundred twenty-seven children underwent diagnostic laparoscopy to confirm the presence or absence of CPPV. Laparoscopy was initially exclusively performed through the umbilicus prior to repair of the known hernia, but over the last 26 months, 250 children successfully underwent laparoscopy through the ipsilateral hernia sac. RESULTS: Of patients younger than 1 year of age, 114 were diagnosed with both a known unilateral hernia and CPPV, whereas 132 had a unilateral hernia only (46% versus 54%). Among children older than 1 year of age, 148 (39%) were diagnosed with unilateral hernia and CPPV, and 233 (61%) were diagnosed with a unilateral hernia alone. After examination under anesthesia, 233 of the 627 patients were suspected of having a CPPV, and 107 were confirmed at laparoscopy (46%). The remaining 394 patients were not believed to have a CPPV. Normal inguinal anatomy was confirmed in 234 patients (59%), but 160 patients were found at laparoscopy to have a CPPV (41%). CONCLUSIONS: A contralateral patent processus vaginalis may be present in a surprising number of young patients being evaluated for a known inguinal hernia. Laparoscopy can be performed without a separate incision when the ipsilateral hernia sac is of sufficient width to allow passage of the scope. Laparoscopy is the best method for evaluating the contralateral inguinal region, particularly in younger children, as it prevents unnecessary inguinal exploration and it decreases the risk that the child will later present with a clinical contralateral hernia.     

Urinary excretion of pancreatic stone protein in diabetic nephropathy

The abnormal persistence of the patent processus vaginalis determines the appearance of four types of pathology, depending on the grade and sort of communication: communicating hydrocele, hydrocele of cord, scrotal hydrocele and intrafunicular hernia. We have revised our casuistry of children with patent processus vaginalis pathology for the two last years (1995-1996), and we have found 75 communicating hydrocele cases, 5 hydrocele of cord and 16 scrotal hydrocele cases, on children between 1 month and 13 years old. The diagnostic was done after physical exploration with transillumination and inguino-scrotal ultrasound. Initially, conservative treatment was followed, which was enough for 58 patients (60.4%). In the 38 cases (39.6%) in which there were no improvement, surgical treatment via inguinal was carried out, with good results in nearly all cases. As a conclusion, we can assert that ultrasound is an excellent diagnostical method for patent processus vaginalis pathology and conservative treatment must have priority upon surgery, since a great number of spontaneous resolutions are observed, most of all on children aged less than two years old.     

Arterial leg ulcers]

OBJECTIVE: To report three patients with persistent Müllerian duct syndrome (PMDS) associated with a unilateral testicular tumour. PATIENTS AND METHODS: Three adults with PMDS and an associated testicular malignancy were evaluated using physical examination, imaging, measurement of tumour markers, surgical exploration and chromosome analysis. RESULTS: The position of the uterus and fallopian tubes differed in all patients: one was in the scrotal sac, another in the abdomen and the third in the left inguinal canal. Two of the patients were cousins and their pedigree showed that they were probably in a sex-limited group. Both also had transverse testicular ectopia; fertility was documented in the younger patient. In all cases, the karyotype was proved to be 46, XY. CONCLUSION: We recommend that the diagnosis of PMDS is made radiologically and that the detection of Müllerian inhibiting factor is mandatory. As malignancy does not occur in the retained Müllerian ducts, hysterectomy should not be performed at abdominal exploration, although orchidectomy should be, because orchidopexy offers only limited protection against future malignancy if performed after 2 years of age. It is not necessary to perform testicular biopsy to detect tumour in the scrotal testis in this syndrome, because an impalpable tumour can be localized by ultrasonography.     

Segmented gene conversion as a mechanism of correction of 18S rRNA pseudogene located outside of rDNA cluster in D. melanogaster

INTRODUCTION: Acute scrotum in the pediatric age is mainly related to surgical causes. Spermatic cord torsion and inguinoscrotal hernia must be ruled out first, because of the possible ischemic damage to gonadal tissue and therefore surgery is sometimes performed directly, thus representing also a diagnostic tool. Spermatic cord torsion is found in two age ranges, namely: the neonatal period, where it usually represents the evolution of an intrauterine process, and the peripubertal period, which is more frequent. An unquestionable and prompt diagnosis is particularly needed because of the extreme sensitivity of gonadal tissue to ischemia. In this particular field, color and power Doppler US, depicting gonadal flow, have greatly increased diagnostic imaging capabilities, which were previously limited to B-mode US. MATERIAL AND METHODS: We examined 19 peripubertal patients with the diagnosis of spermatic cord torsion made on the basis of B-mode US and then confirmed with color Doppler. RESULTS: We found two signs which can be considered highly suggestive of spermatic cord torsion: the spiral twist of spermatic vessels and the peculiar extent of reactive hydrocele, caused by the bell clapper anomaly of the vaginal sac. CONCLUSIONS: The above US patterns are very helpful to diagnose spermatic cord torsion.     

Predicting recovery from common whiplash

Epididymo-orchitis (EO) is said to be extremely rare in infants and children. It is usually diagnosed after scrotal exploration for symptoms which mimic manifestations between EO and torsion of the cord and its appendage. The pathophysiologic mechanisms for the development of EO are not well known. Although some causative agents of EO have been reported, in most cases there was no clear etiology. We report a 3-month-old male infant who had been well until the day prior to admission when irritability, left testicular swelling, scrotal erythema with a hot sensation were noted by his mother. He was treated medically after excluding the possibility of an emergent surgical condition (such as torsion of the cord and its appendage, or incarcerated hernia) by means of physical examinations, abdominal and inguino-scrotal sonography, laboratory studies, and testicular radionuclide scintigraphy. A catheterized sample of urine for culture yielded Escherichia coli. There was the possibility that the EO was caused by hematogenous rather than local spread from an infection of the urinary tract. He was treated with a 10-day course of intravenous cefazolin and amikacin. Following this, he improved clinically and a repeat catheterized urine sample remained sterile on culture. In addition, a bilateral inguinal hernia and hydrocele were detected by inguino-scrotal sonography and were operated on the 11th hospital day. He was discharged on the 16th day of hospitalization and remained well 11 months after discharge.     

Adaptation of a fiber-reinforced restorative system to the rehabilitation of endodontically treated teeth

OBJECTIVE: Review of international literature reveals eight reported cases of laparoscopic obturator hernia repair. Non-specific signs and symptoms make the diagnosis of an obturator hernia difficult. Laparoscopic intervention provides a minimally invasive method to simultaneously diagnose and repair these hernias. METHODS AND PROCEDURES: A 35 year old woman presented with lower abdominal pain, vaginal bleeding, and dyspareunia. During gynecological diagnostic laparoscopy, a pelvic floor hernia was suspected, and a general surgical evaluation was sought. At a subsequent laparoscopy, the diagnosis of a left direct inguinal and a right obturator hernia was made. Both were repaired laparoscopically with polypropylene mesh. RESULTS: At follow-up at one and six weeks postoperatively, the patient's complaints of pain had completely resolved. CONCLUSION: The diagnosis of obturator hernia is problematic. The usual presenting signs and symptoms are non-specific. Without conclusive historical or physical findings, laparoscopy is an excellent method for diagnosing obturator hernia. This entity, once diagnosed laparoscopically, can be repaired simultaneously via laparoscopic mesh technique.     

Intradural lumbar disc herniations: report of three cases

Intradural lumbar disc herniation is a rare pathological entity. Three new cases among a series of 5000 lumbar spine operations are added to the about 60 previous case reports in the literature. None of our patients had undergone lumbar spine surgery before. In one patient the location of the free disc fragment was medial within the dural sac; in two patients the free disc fragment had penetrated the dural sac from the axilla of the nerve root. Pathogenesis is discussed (congenital adhesions of the dura mater to the posterior longitudinal ligament at the lower lumbar spine; weakness of the dura mater ventrally and at the axilla of the nerve root). By multiplanar MRI, the free disc hernia within the dural sac may be shown preoperatively.     

Appendicular mucocele. A report of a case diagnosed preoperatively

Mucocele of the appendix is an unusual clinical entity. Despite a recognized constellation of findings, the diagnosis is not usually made prior to surgical exploration. A 35 year old man is reported in whom clinical evaluation, including US and CT scans, resulted in the correct preoperative diagnosis confirmed at surgery and leading to appropriate operative decisions.     

Reversibility of alcoholic cardiomyopathy. II. Role of atrial fibrillation

A case of an unusual association between hernia and testicular infarction, namely torsion of a normally descended testis within a persistent processus vaginalis, is presented. The advantages of the inguinal ingulinal approach for the exploration of suspected torsion are discussed. Although an operation was performed more than 30 hours after the onset of symptoms the testicle was viable and recovered.
