Sample records for abdominal sacral colpopexy

  1. Abdominal sacral colpopexy with use of synthetic mesh.

    PubMed

    Iosif, C S

    1993-04-01

    Forty patients with post-hysterectomy vaginal vault prolapse underwent surgery at Lund University Hospital between 1983 and 1991. The standard procedure was an abdominal colposacropexy, using Marlex mesh in 25 cases and Gore-Tex mesh in 15. There were no intraoperative complications. One patient developed a recurrent vault prolapse and one patient developed a draining sinus in the vaginal apex. The duration of follow-up has varied between one and ten years. In 39 of the 40 patients (97%), both subjective and objective improvement has been achieved. PMID:8385859

    Lumbosacral osteomyelitis and discitis are usually a result of hematogenous spread; rarely it can result from direct inoculation during a surgical procedure. Bacteria may also track along implanted devices to a different location. This is a rare complication seen from pelvic organ prolapse surgery with sacral colpopexy. A 67-year-old female developed increasing lower back pain four months following a laparoscopic sacral colpopexy. Imaging revealed lumbar 5-sacral 1 (L5-S1) osteomyelitis and discitis with associated phlegmon confirmed by percutaneous biopsy and culture. The patient was treated conservatively with antibiotics, but required laparoscopic removal of the pelvic and vaginal mesh followed by twelve weeks of intravenous antibiotics. The patient has experienced clinical improvement of her back pain. This is an uncommon complication of sacral colpopexy, but physicians must be vigilant and manage aggressively to avoid more serious complications and permanent deficit. PMID:27551651

    OBJECTIVE: To compare the safety and efficacy of abdominal sacral colpopexy and sacrospinous ligament suspension with the use of vaginal mesh for apical prolapse. METHOD: This retrospective study was conducted from 2005 to 2012 and included 89 women with apical prolapse who underwent surgery. Assessments included pre- and postoperative Pelvic Organ Prolapse Quantification (POP-Q) stage. Rates of objective cure and immediate/late complications were compared. RESULTS: In total, 41 of the 89 women underwent sacrospinous ligament suspension, and 48 of the women underwent abdominal sacral colpopexy. A total of 40.4% of the women had vault prolapse (p=0.9361). Most of them had no complications (93.2%) (p=0.9418). Approximately 30% of the women had late complications; local pain was the main symptom and was found only in women who underwent the abdominal procedure (25.6%) (p=0.001). Only the women who were submitted to the vaginal procedure had mesh exposure (18.4%). The objective success rate and the rate of anterior vaginal prolapse (p=0.2970) were similar for both techniques. CONCLUSION: Sacrospinous ligament suspension was as effective and had a similar objective success rate as abdominal sacral colpopexy for the treatment of apical prolapse. Sacrospinous ligament suspension performed with the use of vaginal mesh in the anterior compartment was effective in preventing anterior vaginal prolapse after surgery.

  6. Sacral nerve stimulation.

    PubMed

    Matzel, K E; Stadelmaier, U; Besendörfer, M

    2004-01-01

    The current concept of recruiting residual function of an inadequate pelvic organ by electrostimulation involves stimulation of the sacral spinal nerves at the level of the sacral canal. The rationale for applying SNS to fecal incontinence was based on clinical observations of its effect on bowel habits and anorectal continence function in urologic patients (increased anorectal angulation and anal canal closure pressure) and on anatomic considerations: dissection demonstrated a dual peripheral nerve supply of the striated pelvic floor muscles that govern these functions. Because the sacral spinal nerve site is the most distal common location of this dual nerve supply, stimulating here can elicit both functions. Since the first application of SNS in fecal incontinence in 1994, this technique has been improved, the patient selection process modified, and the spectrum of indications expanded. At present SNS has been applied in more than 1300 patients with fecal incontinence limited.

    In this report, we present two cases of 9-year-old children with spina bifida occulta (SBO) of the sacrum, who were diagnosed with sacral fatigue fractures. In both patients, MRI showed a linear signal void and high signal in sacral ala on the short tau inversion recovery sequence. Sacral SBO at the same level of the sacral fracture was observed in each patient on computed tomography images. These lesions healed with rest. This is the first literature reporting cases with sacral stress fractures who had SBO at the same level of fracture. PMID:26196371

    The Endo Stitch technique has been in use in Geelong since 1994 as the method of performing transvaginal sacrospinous colpopexy (TSC). This article looks at the outcome of 165 of these procedures as assessed by a questionnaire. As the operation is technically easy, has a low complication rate and a high level of patient satisfaction we suggest that the Endo Stitch technique may be the method of choice for TSC.

    2001-02-01

    Stress fractures of the sacrum during pregnancy or the postpartum seem uncommon. We report a new case of nontrauma-related postpartal sacral fracture. Only four similar cases have been reported to date. The patient was 36 years of age and her fracture was diagnosed four weeks after her first delivery. Vitamin D levels were low, but there was no osteomalacia. Other standard laboratory tests were normal, as were absorptiometry measurements at the lumbar spine and femur. Rheumatologists should consider sacral fracture in pregnant or nursing patients with buttock pain. Magnetic resonance imaging is the diagnostic investigation of choice.

  12. Sacral neuromodulation: No more skiing?

    PubMed

    Wöllner, Jens; Pannek, Jürgen

    2016-01-01

    Patients with spinal cord injury (SCI) commonly suffer from neurogenic lower urinary tract dysfunction (NLUTD). Sacral neuromodulation (SNM) offers an alternative in the treatment of detrusor overactivity in patients with NLUTD. We report the cases of three patients with NLUTD due to SCI who received SNM. Due to treatment success, all patients could resume skiing. All suffered from skiing accidents, leading to a decreased effectiveness of SNM. Subsequent evaluation revealed a defect of the impulse generator (IPG) and/or dislocation of the electrodes. Reprogramming or replacement of the IPG or the electrodes resulted in restoration of SNM function. Trauma due to skiing is a potential risk factor for the integrity of SNM. Patients with SNM should be informed about the potential risk of SNM damage by falls and accidents. PMID:26754577

    Mesh erosion is an unfortunate complication of abdominal sacral colpopexy. A sinus tract from the vagina to the sacrum developed in a patient after partial removal of a GORE-TEX Soft Tissue Patch because of mesh erosion. Successful management eventually required complete removal of all GORE-TEX material and resection of the sinus tract. PMID:10486501

    This case report concerns a 62-year-old woman with spontaneous infrarenal abdominal aortic dissection, which developed into claudication and rest pain in the lower extremity. Multi-row detector computed tomography showed the entry site of the abdominal aortic dissection at the second lumbar artery, while the reentry site was found intraoperatively at the median sacral artery, indicating that the false lumen had progressed and compressed the true lumen. A direct approach involving grafting appears to be an effective procedure for resolving mesenteric and lower extremity hypoperfusion due to aortic dissection with a dilated false channel, even during the acute period.

    Helbig, Doris

    2016-01-01

    Subcutaneous myxopapillary or sacral ependymoma are rare tumors mostly developing in children or adolescents. The majority occurs in the sacrococcygeal region. There are numerous clinical and histopathological differential diagnoses. Owing to the fact that there have been rare reported cases that followed an aggressive course and in which the patient succumbed to metastatic disease, long term follow-up is necessary despite complete excision. We describe here a 25-year-old male patient with a histological unusual subcutaneous sacral ependymoma and discuss the differential diagnosis as well as treatment options. PMID:26289839

    2014-01-01

    Chordomas are rare, low grade, malignant tumours derived from the ectopic remnants of the notochord that line the axial skeleton. They are characterised by their slow growth, long disease course and propensity for local relapse. Furthermore, up to 40% of non-cranial chordomas metastasise. We describe the first reported case of a hand metastasis arising from a conventional sacral chordoma after carbon ion radiotherapy. The common occurrence of distant metastasis with chordomas makes it important to perform a systemic examination, in part because their resection might improve patient prognosis. PMID:25350167

    An elderly woman with a chronic decubitus sacral ulcer presented to the emergency department with sepsis. A computed tomography of her abdomen showed diffuse gas extending throughout the thoracolumbar spinal canal. Pneumorrhachis is a rare radiographic finding defined as gas within the spinal canal. There are many causes of pneumorrhachis ranging from trauma to infection. In this case the pneumorrhachis was caused by direct spread of gas-forming organisms from vertebral osteomyelitis. Emergency physicians should know about the implication of gas in the spinal canal in the setting of sepsis. PMID:27429699

    2015-01-01

    Sacral stress fractures are common in elderly people. However, sacral stress fracture should be always screened in the differential diagnoses of low back pain during the postpartum period. We present a case of sacral fracture in a thirty-six-year-old woman with low back pain and severe right buttock pain two days after cesarean section delivery of a 3.9 Kg baby. The diagnosis was confirmed by MRI and CT scan, while X-ray was unable to detect the fracture. Contribution of mechanical factors during the cesarean section is not a reasonable cause of sacral fracture. Pregnancy and lactation could be risk factors for sacral stress fracture even in atraumatic delivery such as cesarean section. Our patient had no risk factors for osteoporosis except for pregnancy and lactation. Transient or focal osteoporosis is challenging to assess and it cannot be ruled out even if serum test and mineral density are within the normal range. PMID:26246926

  1. Anterior sacral meningocele: management in gynecological practice.

    PubMed

    Manson, F; Comalli-Dillon, K; Moriaux, A

    2007-11-01

    We describe the case of a young woman with anterior sacral meningocele (ASM), initially identified during a routine ultrasound examination and subsequently diagnosed using magnetic resonance imaging (MRI). ASM is a rare disorder characterized by uni- or multilocular extensions of the meninges from the sacral spinal canal to the retroperitoneal presacral space. Common symptoms include lower back and pelvic pain, constipation, difficulties in defecation, dysmenorrhea and dyspareunia, and urinary incontinence, retention or urgency. Perineal and lower-extremity paresthesias may present when nerve roots are affected. Despite its more posterior location, ASM can mimic an ovarian cyst or other adnexal cystic mass, and in the obstetric patient can present a mechanical obstacle to delivery with a risk of rupture and infection during labor and delivery. Although it is a rare condition, we feel that awareness of the etiology, presentation and imaging characteristics of ASM is of importance and have therefore carried out a review of the literature, taking into account case findings and the obstetric and gynecological management of this disorder.

  2. Predictability of sacral base levelness based on iliac crest measurements.

    PubMed

    Dott, G A; Hart, C L; McKay, C

    1994-05-01

    A level sacral base plane is necessary to allow normalization of complex lumbosacral mechanics. Palpatory examinations are often used to evaluate for leg length discrepancy and pelvic obliquity despite improved accuracy and consistency of radiographic techniques. Treatment based on palpatory examinations suppose a direct and consistent relationship between the pelvic bones (innominates) and the sacral base. To evaluate the relationship between iliac crest levelness and sacral base levelness, a radiographic postural survey in the upright, weight-bearing position was performed on 358 men and women thought to have pelvic obliquity. Of these subjects, 293 demonstrated unlevel iliac crest heights or sacral base > or = 3/16 inch (4.76 mm), with iliac crest heights accurately predicting sacral base position 62% of the time. At > or = 3/8 inch (9.53 mm), 68% of the cases were accurately predicted. When the criterion for unlevelness was increased to > or = 1/2 inch (12.70 mm), the predictive accuracy improved to 83%. Radiographic findings in this study demonstrate a significant difference between iliac crest heights and sacral base position. In cases of mild to moderate short leg syndromes, the iliac crest height is an unreliable predictor of the direction or degree of sacral base levelness. PMID:8056627

    Cystic spinal lesions with characteristic patterns, such as the presence of haematic fluid-fluid levels (H-FFL), have been associated with many tumoral lineages, more frequently with aneurysmal bone cyst (ABC) and exceptionally with metastasis. We present the case of a 60-year-old man with the finding of a sacral cystic bone lesion with H-FFL, with initial suspicion of ABC and confirmed diagnosis of metastasis. The case presented is, to our knowledge, the second case published of spinal cystic bone metastasis with H-FFL pattern with unknown primary tumour at the time of diagnosis and the only one that received resective surgical treatment, achieving pulmonary and metastatic disease control with good quality of life after 1 year of follow up.

    Baldwin, Mathew J; Tucker, Laura J

    2014-01-01

    Introduction Sacral insufficiency fractures are an important cause of lower back pain in the elderly. Clinically and radiologically, they must be distinguished from osseous metastases, which frequently coexist. To date, no case report has comprehensively explored the full range of diagnostic hurdles and potential pitfalls. Case presentation We report the case of a 70-year-old Caucasian female who presented to our services with a short history of progressive back pain without any history of trauma. A prior history of breast cancer was noted. Bone scintigraphy was initially reported as consistent with metastatic sacral deposits. Further characterization with magnetic resonance imaging and computed tomography revealed bilateral insufficiency fractures of the sacral alar. The patient responded well to conservative management. Conclusion To avoid misdiagnosis, particularly in those who are also at risk of osseous metastases, sacral insufficiency fractures must always be considered as a cause of lower back pain.

    Sacral insufficiency fractures (SIFs) are a common cause of back pain in the elderly. SIFs mimic the symptoms of lumbar spine pathology and so are commonly missed or underdiagnosed. Here we present four cases of missed SIFs that were subsequently identified and treated. One patient was treated as mechanical lower back ache, another patient underwent root block and two patients underwent surgery for lumbar canal stenosis. None experienced relief of their symptoms after these procedures. Retrospective analysis of X-ray and magnetic resonance imaging data revealed SIFs that were confirmed by computed tomography scans. All four patients were treated for underlying osteoporosis. Two patients who underwent surgery were treated conservatively and other two were treated by sacroplasty involving injection of cement into the fracture. Sacroplasty produced immediate pain relief and early mobilization compared to the conservative group. SIFs should always be considered in the differential diagnosis of an elderly patient presenting with low back symptoms. Sacroplasty can be considered for immediate pain relief and rapid mobilization.

    1988-01-01

    The neuroanatomy and neurophysiology of the external urethral closure mechanisms still are under debate because the motor fibers that emanate from the sacral plexus and pudendal nerve to supply this segment have not been traced, nor has their functional interrelationship been established. Therefore, we dissected 3 male human cadavers (aged 31 to 69 years) by tracing the entire sacral plexus, particularly the pudendal nerve, from the cauda equina throughout the branching of the nerves to their final destination. The dissection demonstrated that the extrinsic urethral sphincter, formed by the rhabdosphincter around the membranous urethra as well as the levator ani muscle and pelvic floor (especially the transversus perinei muscle), is innervated by somatic nerve fibers that emanate primarily from sacral roots S2 and S3. In 5 patients with neurogenic lower urinary tract dysfunction electrostimulation of the sacral root and pudendal nerve markedly increased intraurethral closure pressures. Stimulation of the pudendal nerve or its transversus perinei branch alone resulted in an increase in intraurethral closure pressure to 60 to 70 cm. water--an increase similar to that produced by stimulation of the sacral root without neurotomy. By means of neurotomy and/or neural blockade with lidocaine we were able to differentiate between the contributions of each muscular element to the external sphincteric mechanism. Almost 70 per cent of the closure pressure of the external urethral sphincter is induced by stimulation of the S3 ventral root, while the other 30 per cent derives from S2 and S4 neuronal impulses.

  10. Pubic and sacral insufficiency fractures: clinical course and radiologic findings

    1985-09-01

    Distinctive vertical insufficiency fractures of the pelvis were found in nine osteopenic patients. Each patient had subacute pelvic pain without antecedent trauma. The sacral fractures healed fairly quickly, but the pubic fractures often had a protracted course. All nine patients had skeletal demineralization due to metabolic bone disease, radiation therapy, or multiple myeloma. Recognition of the association between public and sacral insufficiently fractures should aid in recognizing the diffuse nature of the skeletal disease so that unnecessary biopsy of the fracture sites can be avoided. Plain films, tomographic scans, and radionuclide bone scans are reviewed.

  13. High Frequency Sacral Root Nerve Block Allows Bladder Voiding

    PubMed Central

    Boger, Adam S.; Bhadra, Narendra; Gustafson, Kenneth J

    2013-01-01

    1) Aims Dyssynergic reflexive external urethral sphincter (EUS) activity following spinal cord injury can prevent bladder voiding, resulting in significant medical complications. Irreversible sphincterotomies or neurotomies can prevent EUS activation and allow bladder voiding, but may cause incontinence or loss of sacral reflexes. We investigated whether kilohertz frequency (KF) electrical conduction block of the sacral roots could prevent EUS activation and allow bladder voiding. 2) Methods The S2 sacral nerve roots were stimulated bilaterally to generate bladder pressure in 6 cats. One S1 nerve root was stimulated proximally (20 Hz biphasic pulse trains) to evoke EUS pressure, simulating worst-case dyssynergic EUS reflexes. KF waveforms (12.5 kHz biphasic square wave) applied to an electrode implanted distally on the S1 nerve root blocked nerve conduction, preventing the increase in EUS pressure and allowing voiding. 3) Results Applying KF waveforms increased bladder voiding in single, limited-duration trials from 3 ± 6% to 59 ± 12%. Voiding could be increased to 82 ± 9% of the initial bladder volume by repeating or increasing the duration of the trials. 4) Conclusions Sacral nerve block can prevent EUS activation and allow complete bladder voiding, potentially eliminating the need for a neurotomy. Eliminating neurotomy requirements could increase patient acceptance of bladder voiding neuroprostheses, increasing patient quality of life and reducing the cost of patient care. PMID:22473837

    Study Design Case report. Objective Sacral fractures, traumatic or atraumatic, are a rather rare cause of low back pain. The majority of the cases of pregnancy-related sacral fractures are reported as a postpartum complication, and only few cases of sacral atraumatic fractures have been reported in the last trimester of the pregnancy. The aim of this study is to report a rare case of atraumatic sacral fracture in the third trimester of pregnancy. Methods We report the case of a 30-year-old Caucasian European woman during her 37th week (36 weeks and 4 days) of gestation, who complained during her scheduled obstetric examination of continuous low back pain with no associated history of trauma. The patient performed activities of daily living with a normal level of fatigue and reported no running or walking long distances. She was examined in our department, and a magnetic resonance imaging scan was performed that showed a vertical nondisplaced fracture in her left sacrum. Results The patient was treated conservatively, and analgesics were administrated according to the consensus of the orthopedic and the anesthesiology departments. No further complications were recognized in the remaining period of her pregnancy, and a healthy child was born by caesarean section. Conclusions Atraumatic fractures of the sacrum should be included in the differentiated diagnosis of pregnant patients with low back pain. PMID:26131396

    The authors think that the sacral epidural anaesthesia effected with Mepivacaine 3%, 6 ml (180 mg) and Fentanyl 2 ml (100 mcg) is perfectly indicated for the proctologic surgery as it is of simple execution and presents a short latency (12 min.), good deepness and perfect haemodynamic stability. Besides, it does not endanger the lower limbs innervation. No urinary retention.

    AIM: To investigate inpatient length of stay (LOS), complication rates, and readmission rates for sacral fracture patients based on operative approach. METHODS: All patients who presented to a large tertiary care center with isolated sacral fractures in an 11-year period were included in a retrospective chart review. Operative approach (open reduction internal fixation vs percutaneous) was noted, as well as age, gender, race, and American Society of Anesthesiologists’ score. Complications included infection, nonunion and malunion, deep venous thrombosis, and hardware problems; 90-d readmissions were broken down into infection, surgical revision of the sacral fracture, and medical complications. LOS was collected for the initial admission and readmission visits if applicable. Fisher’s exact and non-parametric t-tests (Mann-Whitney U tests) were employed to compare LOS, complications, and readmissions between open and percutaneous approaches. RESULTS: Ninety-four patients with isolated sacral fractures were identified: 31 (30.4%) who underwent open reduction and internal fixation (ORIF) vs 63 (67.0%) who underwent percutaneous fixation. There was a significant difference in LOS based on operative approach: 9.1 d for ORIF patients vs 6.1 d for percutaneous patients (P = 0.043), amounting to a difference in cost of $13590. Ten patients in the study developed complications, with no significant difference in complication rates or reasons for complications between the two groups (19.4% for ORIF patients vs 6.3% for percutaneous patients). Eight patients were readmitted, with no significant difference in readmission rates or reasons for readmission between the two groups (9.5% percutaneous vs 6.5% ORIF). CONCLUSION: There is a significant difference in LOS based on operative approach for sacral fracture patients. Given similar complications and readmission rates, we recommend a percutaneous approach.

    Abstract The purpose of this study is to determine the reliability and validity of a goniometric measurement of the vertical angle of the sacrum and sacral angle (SA), and their relationships to lumbar degeneration. A herniated lumbar disc is one of the most frequent medical issues. Investigators in a number of studies have reported associated risk factors for prevalent disc degeneration. Atypical lumbosacral angles and curvature are thought to contribute to the degradation of the spine by many researchers. This study analyzed 360 patients referred to our clinic from 2013 to 2015 due to low back pain. A cross-sectional case–control study was designed in order to compare the sagittal alignment of the lumbosacral area in 3 groups of patients suffering from LBP. A total 120 patients were in a control group with a normal lumbar magnetic resonance imaging (MRI), 120 patients had lumbar disk herniation (LDH), and 120 patients had spinal stenosis. From the sagittal plan of lumbar MRI, SA and vertical angle of sacral curvature (VASC) were determined and then analyzed. The means of VASC in these groups were: 38.98 (SD: 6.36 ± 0.58), 40.89 (SD: 7.69 ± 0.69), and 40.54 (SD: 7.13 ± 0.92), respectively (P = 0.089). Moreover, studies of SA in 3 groups showed that the means of SA were: 39.30 (SD: 6.69 ± 0.63), 40.52 (SD: 7.47 ± 0.65), and 35.63 (SD: 6.07 ± 0.79), respectively. Relation between SA and spinal stenosis was just statistically significant (P ≤ 0.05). One significant limitation of our study is the lack of standing MRI for increased accuracy of measurement. However, we were reluctant to give patients needless exposure to radiation from conventional X-ray, and instead used MRI scans. We did not find any significant correlation between the VASC and LDH in lumbar MRI. Also, SA is not an independent risk factor for LDH in men and women. We suggested that there are several biomechanical factors involved in LDH. PMID:26871821

  18. Abdominal Sepsis.

    Abdominal infections are an important challenge for the intensive care physician. In an era of increasing antimicrobial resistance, selecting the appropriate regimen is important and, with new drugs coming to the market, correct use is important more than ever before and abdominal infections are an excellent target for antimicrobial stewardship programs. Biomarkers may be helpful, but their exact role in managing abdominal infections remains incompletely understood. Source control also remains an ongoing conundrum, and evidence is increasing that its importance supersedes the impact of antibiotic therapy. New strategies such as open abdomen management may offer added benefit in severely ill patients, but more data are needed to identify its exact role. The role of fungi and the need for antifungal coverage, on the other hand, have been investigated extensively in recent years, but at this point, it remains unclear who requires empirical as well as directed therapy.

    A 28-year-old woman presented with abdominal pain. Ultrasonograhic examination showed a pre-sacral mass, with complex structure and well delimitated cystss with thick walls. The resected specimen was 7.5 x 6 x 4 cm in size, well circumscribed and yellow in colour, with cysstic change containing mucoid-like material. Histologically, the lesion was composed of spindle cells with high cellularity and rich vascularization with a haemangiopericytoma-like pattern. The diagnosis of solitary fibrous tumour (SFT) was made. The differential diagnosis for SFT of the pre-sacral spaace involves haemangiopericytoma, GIST, malignant mesothelioma, synovial sarcoma, leiomyomatous tumours and granulosa cell tumour. Immunohistochemical studies revealed reactivity for CD34, CD99 and Bcl-2, but no staining for desmin, inhibin, c-kit, EMA, CK, SMA, S-100 and CD31, confirming a diagnosis of SFT. Although SFT is usually associated with a favourable prognosis, close follow-up is recommended because of the limited information on its long-term behaviour.

    2015-01-01

    Chordomas are known as rare primary malign tumours that have formed from primitive notochord remains. Sacral chordomas grow slowly but locally and aggressively. Chordomas are locally invasive and have low tendency to metastasis and have a poor prognosis in long-term follow-up. Metastasis may be seen in a rate of 5–40% of the chordomas. Metastasis of chordomas is common in liver, lung, lymph nodes, peritoneum, and brain. The treatment approaches, including surgery, have been discussed in the literature before. Susceptibility to radiotherapy and chemotherapy is controversial in these tumours. The success of surgical treatment affects survival directly. In this report, we will report a sacral chordoma case in which an intraperitoneal distant metastasis occurred and discuss the surgical approach. PMID:25649759

    2016-01-01

    Background: Resection of sacral chordomas is challenging. The anatomy is complex, and there are often no bony landmarks to guide the resection. Achieving adequate surgical margins is, therefore, difficult, and the recurrence rate is high. Use of computer navigation may allow optimal preoperative planning and improve precision in tumor resection. The purpose of this study was to evaluate the safety and feasibility of computer navigation-aided resection of sacral chordomas. Methods: Between 2007 and 2013, a total of 26 patients with sacral chordoma underwent computer navigation-aided surgery were included and followed for a minimum of 18 months. There were 21 primary cases and 5 recurrent cases, with a mean age of 55.8 years old (range: 35–84 years old). Tumors were located above the level of the S3 neural foramen in 23 patients and below the level of the S3 neural foramen in 3 patients. Three-dimensional images were reconstructed with a computed tomography-based navigation system combined with the magnetic resonance images using the navigation software. Tumors were resected via a posterior approach assisted by the computer navigation. Mean follow-up was 38.6 months (range: 18–84 months). Results: Mean operative time was 307 min. Mean intraoperative blood loss was 3065 ml. For computer navigation, the mean registration deviation during surgery was 1.7 mm. There were 18 wide resections, 4 marginal resections, and 4 intralesional resections. All patients were alive at the final follow-up, with 2 (7.7%) exhibiting tumor recurrence. The other 24 patients were tumor-free. The mean Musculoskeletal Tumor Society Score was 27.3 (range: 19–30). Conclusions: Computer-assisted navigation can be safely applied to the resection of the sacral chordomas, allowing execution of preoperative plans, and achieving good oncological outcomes. Nevertheless, this needs to be accomplished by surgeons with adequate experience and skill. PMID:26830986

    2016-01-01

    The objective of this study was to describe our experience using sacral neuromodulation to treat urinary urgency, frequency, urge incontinence, and chronic urinary retention in patients with cardiac pacemakers. With the increasingly widespread use of InterStim for bladder function restoration, we are seeing more complex patients with multiple comorbidities, including cardiac conditions. Herein, we report 3 cases of individuals with cardiac pacemakers who underwent InterStim implantation to treat urinary conditions. This study is a case series of 3 patients with cardiac pacemakers who underwent sacral neuromodulation to treat refractory voiding dysfunction. The initial patient screening for InterStim therapy involved percutaneous nerve evaluation (PNE), in which a temporary untined lead wire was placed through the S3 foramen. Patients who did not respond to PNE proceeded to a staged implant. All patients in this study had a greater than 50% improvement of their urinary symptoms during the initial trial and underwent placement of the InterStim implantable pulse generator (IPG). Postoperative programming was done under electrocardiogram monitoring by a cardiologist. No interference was observed between the Inter-Stim IPG and the cardiac pacemaker. In this group of patients, sacral neuromodulation in the presence of a cardiac pacemaker appears to have been safe. PMID:27706012

    Sacral chordomas are rare, slow-growing tumours that are amenable to surgery, but unfortunately often diagnosed late. The aim of the study was to identify presenting symptoms, which may aid diagnosis and reduce the treatment time. Forty-four patients were identified with sacral chordoma between 1989 and 2006. Clinical and pathological records were reviewed retrospectively to elicit the symptoms recorded prior to diagnosis, duration of symptoms, surgical treatment, size of tumour and survival. Eleven patients were excluded, leaving 33 patients in the study group. Thirty-one patients had chordomas arising from the sacrum and two patients from the coccyx. The mean duration of symptoms prior to diagnosis was 120 weeks (2.3 years), with a median of length of 104 weeks (two years) and range of 26 to 416 weeks (0.5 to eight years). The mean maximum tumour size at resection was 8.3 cm, with a mean volume of 614 cm3 (range 9–2,113 cm3). Pain, typically dull and worse with sitting, was the most common presenting symptom in 85% of patients. The classic symptoms of cauda equina (saddle anaesthesia, bladder or bowel dysfunction) occurred in 70% patients (23 patients). Sacral chordoma should be considered in cases of back pain with coccydynia, especially with neurological symptoms. PMID:17205349

    The term, sacral fracture with traumatic spino-pelvic dissociation, is applied to those fractures of the sacrum in which there are both transverse and sagittal fracture lines in the sacrum, leading to a mechanical dissociation of the spine and the proximal fragment of the sacrum from the remaining sacrum and the pelvis. It is a quite rare pathological condition, and probably underdiagnosed. As it usually results from a high energy multiple trauma, an early diagnosis and treatment are mandatory for a better functional prognosis. We present a literature review of this relatively unknown injury.

    Previously, a computer-based navigation system has not been used routinely for en-bloc resection of sacral tumors. In order to improve the accuracy of tumor resection, O-arm navigation was used to join anterior and posterior osteotomies during an en-bloc resection of a sacral Ewing's sarcoma. This case study describes the technique for en-bloc resection of a sacral Ewing's sarcoma guided by O-arm computer navigation and intraoperative neurophysiological monitoring (IONM). An 18-year-old male presented with weakness in his left lower extremity. MRI of the patient's spine showed a sacral mass causing compression of left S1 and S2 roots. A surgical resection was planned with anterior and posterior approaches. An O-arm computer navigation system was used to assist in meeting anterior osteotomy cuts with the posterior cuts to ensure complete resection of the sacral tumor with a safe margin. Computer-assisted navigation was used along with IONM during this procedure to help guide the surgical team in an adequate tumor resection. There were no complications related to the use of the O-arm or the navigation system. Computer navigation guidance is both useful and safe in sacral tumor resections. It enhanced the accuracy of the en-bloc removal of a sacral tumor with safe margins while protecting neural function and minimizing recurrence.

    For this technique, bone needle is introduced into the S1 vertebral body through the interpedicular route by penetrating the central spinal canal at the level of S3-4 and passing through the vertebral body of S2-3 parallel to the anterior border of sacrum. With the interpedicular approach, two sacral vertebral bodies can be injected in one session and lower sacral body injection also is available. interpedicular technique is a safe, practical, and effective technique for the treatment of sacral vertebral body pathologic fractures.

    Pelvic organ prolapse is a common condition, occurring in up to 11% of women in the United States. Often, pelvic organ prolapse recurs after surgery; when it recurs after hysterectomy, it frequently presents as vaginal apical prolapse. There are many different surgical treatments for vaginal apical prolapse; among them, abdominal sacral colpopexy is considered the gold standard. However, recent data reveal that other surgical procedures also result in good outcome. This review discusses the various surgical treatments for vaginal apical prolapse including their risks and benefits. PMID:27462591

    Lumbo-sacral chordomas are rare skeletal sarcomas that originate from the remnant notochord. There are approximately 35 lumbo-sacral chordomas reported annually in the U.S.A. The understanding of this rare human cancer is limited to observations of its clinical behavior and embryonic link. We performed chromosome and molecular analyses from five surgically harvested chordomas in an effort to document genetic abnormalities and to further understand its tumor biology. Cytogenetically, four of five patients had entirely normal chromosomes. One patient had several abnormalities seen in one of 100 cells including a translocation with breakpoints at bands 5q13 and 7q22, loss of one X chromosome and an extra chromosome 14. There was no evidence of monosomy X or trisomy 14 seen with interphase in situ hybridization using biotin-labeled alpha satellite chromosome specific probes for chromosome 14/22 and X. Telomere integrity is required to protect termini from illegitimate recombination. Typically telomeric reduction occurs in senescent fibroblasts in vivo aging and several human solid tumors. A telomeric probe (TTAGGG){sub 50} was hybridized to genomic DNA isolated from chordoma cells and digested with Hinf I which allows the telomeric DNA to remain intact. The tumor DNA was paired with leukocyte DNA from age-matched controls and revealed telomere elongation in all four patients studied with molecular genetic techniques. Telomerase activity is required to maintain telomere integrity and is not present in normal somatic cells. It is determined by visualizing the sizes of the electrophoresis gel-separated radioactive telomeric fragments assembled during incubation of cytoplasmic extracts containing telomerase. Telomerase activity was detected when compared with HeLa cells, a positive control. In addition, no telomerase activity was detected from the chordoma patient`s fibroblasts.

    Identification of the neural pathways involved in retraining the spinal central pattern generators (CPGs) by afferent input in the absence of descending supraspinal control is feasible in isolated rodent spinal cords where the locomotor CPGs are potently activated by sacrocaudal afferent (SCA) input. Here we study the involvement of sacral neurons projecting rostrally through the ventral funiculi (VF) in activation of the CPGs by sensory stimulation. Fluorescent labeling and immunostaining showed that VF neurons are innervated by primary afferents immunoreactive for vesicular glutamate transporters 1 and 2 and by intraspinal neurons. Calcium imaging revealed that 55% of the VF neurons were activated by SCA stimulation. The activity of VF neurons and the sacral and lumbar CPGs was abolished when non-NMDA receptors in the sacral segments were blocked by the antagonist CNQX. When sacral NMDA receptors were blocked by APV, the sacral CPGs were suppressed, VF neurons with nonrhythmic activity were recruited and a moderate-drive locomotor rhythm developed during SCA stimulation. In contrast, when the sacral CPGs were activated by SCA stimulation, rhythmic and nonrhythmic VF neurons were recruited and the locomotor rhythm was most powerful. The activity of 73 and 27% of the rhythmic VF neurons was in-phase with the ipsilateral and contralateral motor output, respectively. Collectively, our studies indicate that sacral VF neurons serve as a major link between SCA and the hindlimb CPGs and that the ability of SCA to induce stepping can be enhanced by the sacral CPGs. The nature of the ascending drive to lumbar CPGs, the identity of subpopulations of VF neurons, and their potential role in activating the locomotor rhythm are discussed. PMID:23303951

    Study Design Survey study. Objective To determine the global perspective on controversial aspects of sacral fracture classifications. Methods While developing the AOSpine Sacral Injury Classification System, a survey was sent to all members of AOSpine and AOTrauma. The survey asked four yes-or-no questions to help determine the best way to handle controversial aspects of sacral fractures in future classifications. Chi-square tests were initially used to compare surgeons' answers to the four key questions of the survey, and then the data was modeled through multivariable logistic regression analysis. Results A total of 474 surgeons answered all questions in the survey. Overall 86.9% of respondents felt that the proposed hierarchical nature of injuries was appropriate, and 77.8% of respondents agreed that that the risk of neurologic injury is highest in a vertical fracture through the foramen. Almost 80% of respondents felt that the separation of injuries based on the integrity of L5–S1 facet was appropriate, and 83.8% of surgeons agreed that a nondisplaced sacral U fracture is a clinically relevant entity. Conclusion This study determines the global perspective on controversial areas in the injury patterns of sacral fractures and demonstrates that the development of a comprehensive and universally accepted sacral classification is possible.

  1. "Lucy" (A.L. 288-1) had five sacral vertebrae.

    PubMed

    Russo, Gabrielle A; Williams, Scott A

    2015-02-01

    A "long-backed" scenario of hominin vertebral evolution posits that early hominins possessed six lumbar vertebrae coupled with a high frequency of four sacral vertebrae (7:12-13:6:4), a configuration acquired from a hominin-panin last common ancestor (PLCA) having a vertebral formula of 7:13:6-7:4. One founding line of evidence for this hypothesis is the recent assertion that the "Lucy" sacrum (A.L. 288-1an, Australopithecus afarensis) consists of four sacral vertebrae and a partially-fused first coccygeal vertebra (Co1), rather than five sacral vertebrae as in modern humans. This study reassesses the number of sacral vertebrae in Lucy by reexamining the distal end of A.L.288-1an in the context of a comparative sample of modern human sacra and Co1 vertebrae, and the sacrum of A. sediba (MH2). Results demonstrate that, similar to S5 in modern humans and A. sediba, the last vertebra in A.L. 288-1an exhibits inferiorly-projecting (right side) cornua and a kidney-shaped inferior body articular surface. This morphology is inconsistent with that of fused or isolated Co1 vertebrae in humans, which either lack cornua or possess only superiorly-projecting cornua, and have more circularly-shaped inferior body articular surfaces. The level at which the hiatus' apex is located is also more compatible with typical five-element modern human sacra and A. sediba than if only four sacral vertebrae are present. Our observations suggest that A.L. 288-1 possessed five sacral vertebrae as in modern humans; thus, sacral number in "Lucy" does not indicate a directional change in vertebral count that can provide information on the PLCA ancestral condition.

    The purpose of this study is to determine the reliability and validity of a goniometric measurement of the vertical angle of the sacrum and sacral angle (SA), and their relationships to lumbar degeneration.A herniated lumbar disc is one of the most frequent medical issues. Investigators in a number of studies have reported associated risk factors for prevalent disc degeneration. Atypical lumbosacral angles and curvature are thought to contribute to the degradation of the spine by many researchers. This study analyzed 360 patients referred to our clinic from 2013 to 2015 due to low back pain. A cross-sectional case-control study was designed in order to compare the sagittal alignment of the lumbosacral area in 3 groups of patients suffering from LBP. A total 120 patients were in a control group with a normal lumbar magnetic resonance imaging (MRI), 120 patients had lumbar disk herniation (LDH), and 120 patients had spinal stenosis. From the sagittal plan of lumbar MRI, SA and vertical angle of sacral curvature (VASC) were determined and then analyzed.The means of VASC in these groups were: 38.98 (SD: 6.36 ± 0.58), 40.89 (SD: 7.69 ± 0.69), and 40.54 (SD: 7.13 ± 0.92), respectively (P = 0.089). Moreover, studies of SA in 3 groups showed that the means of SA were: 39.30 (SD: 6.69 ± 0.63), 40.52 (SD: 7.47 ± 0.65), and 35.63 (SD: 6.07 ± 0.79), respectively. Relation between SA and spinal stenosis was just statistically significant (P ≤ 0.05).One significant limitation of our study is the lack of standing MRI for increased accuracy of measurement. However, we were reluctant to give patients needless exposure to radiation from conventional X-ray, and instead used MRI scans. We did not find any significant correlation between the VASC and LDH in lumbar MRI. Also, SA is not an independent risk factor for LDH in men and women. We suggested that there are several biomechanical factors involved in LDH. PMID:26871821

    Importance Over 225,000 surgeries are performed annually in the U.S. for pelvic organ prolapse (POP). Abdominal sacrocolpopexy is considered the most durable POP surgery, but little is known about long-term effectiveness and adverse events. Objective To describe anatomic and symptomatic outcomes up to 7 years after abdominal sacrocolpopexy, and to determine whether these are affected by concomitant anti-incontinence surgery (Burch urethropexy). Design, setting, participants Long-term follow-up of the randomized, masked 2-year CARE trial (Colpopexy And urinary Reduction Efforts). Participants were stress continent women undergoing abdominal sacrocolpopexy between 2002–5 for symptomatic POP randomized to concomitant urethropexy or not. 92% (215/233) of eligible 2-year CARE trial completers enrolled into this extended study with 181 (84%) and 126 (59%) completing 5 and 7 years follow-up, respectively. Median follow-up was 7 years. Main Outcome Measures POP: Symptomatic failure: POP retreatment or reporting bulge on Pelvic Floor Distress Inventory (PFDI); Anatomic failure: POP retreatment or Pelvic Organ Prolapse Quantification demonstrating descent of the vaginal apex descend below upper third of the vagina or anterior or posterior vaginal wall prolapse beyond the hymen. Urinary incontinence (UI): Stress UI: more than 1 stress urinary incontinence symptom on PFDI or interval treatment; Overall UI: score ≥ 3 on Incontinence Severity Index. Results By year 7, the estimated probabilities of failure (POP, SUI, UI) from parametric survival modeling for the urethropexy and no urethropexy groups respectively were were 0.27 and 0.22 for anatomic POP (difference 0.050; 95% CI −0.161, 0.271), 0.29 and 0.24 for symptomatic POP (0.049; −0.060, 0.162), 0.48 and 0.34 for composite POP (0.134; −0.096, 0.322), 0.62 and 0.77 for SUI (−0.153; −0.268, 0.030) 0.75 and 0.81 for overall UI (−0.064; −0.161, 0.032).

    Abdominal cerebrospinal fluid pseudocyst in an infrequent complication of ventriculoperitoneal (VP) shunts. We reviewed ten patients with abdominal pseudocyst. There were five girls and five boys, aged between 4 months and 14 years. The number of shunt procedures prior to the presentation varied between one and five. Only one patient had had a previous shunt infection. No patients had undergone prior abdominal surgery other than VP shunting. The time from the last shunting procedure to the development of abdominal pseudocyst ranged from 3 weeks to 5 years. Presenting symptoms and signs were mainly related to abdominal complaints in all patients. Three patients also had signs of shunt malfunction. The diagnosis was made by ultrasound in all patients. Shunt infection was determined in six patients. Repositioning if the peritoneal catheter seemed to have a higher rate of recurrence. The diagnosis of abdominal pseudocyst should be considered in VP-shunted patients presenting with abdominal complaints.

    The abdominal compartment is separated from the thoracic compartment by the diaphragm. Under normal circumstances, a large portion of the venous return crosses the splanchnic and nonsplanchnic abdominal regions before entering the thorax and the right side of the heart. Mechanical ventilation may affect abdominal venous return independent of its interactions at the thoracic level. Changes in pressure in the intra-abdominal compartment may have important implications for organ function within the thorax, particularly if there is a sustained rise in intra-abdominal pressure. It is important to understand the consequences of abdominal pressure changes on respiratory and circulatory physiology. This article elucidates important abdominal-respiratory-circulatory interactions and their clinical effects. PMID:27016167

    Patient: Female, 28 Final Diagnosis: Sacral stress fracture Symptoms: Lumbosacral pain during pregnancy Medication: — Clinical Procedure: Activity modification • conservative treatment Specialty: Orthopedics and Traumatology Objective: Challenging differential diagnosis Background: Sacral stress fracture during pregnancy is an uncommon condition with unclear pathophysiology, presenting with non-specific symptoms and clinical findings. To date, few cases have been published in the literature describing the occurrence of sacral stress fracture during pregnancy. Case Report: We report a 28-year-old primigravid patient who developed lumbosacral pain at the end of the second trimester. Symptoms were overlooked throughout pregnancy and the postpartum period, resulting in the development of secondary chronic gait and balance problems. Conclusions: Stress fracture of the sacrum should be included in the differential diagnosis of low back and sacral pain during pregnancy. Its prevalence is probably underestimated because of the lack of specificity of the symptoms. Plain radiographs are not appropriate due to radiation exclusion; magnetic resonance is the only method that can be applied safely. There is limited information on natural history but many patients are expected to have a benign course. However, misdiagnosis may lead to prolonged morbidity and the development of secondary gait abnormalities. Stress fracture of the sacrum should be included in the differential diagnosis of low back and sacral pain during pregnancy. A high index of suspicion is necessary to establish an early diagnosis and appropriate treatment. PMID:25656418

    Pudendal neuralgia is a debilitating pain syndrome, and finding long-lasting treatment modalities has been challenging in pain management. The pudendal nerve has sensory and motor functions, and influences autonomic functions. Thus, entrapment or damage of this nerve can have multiple serious implications. The constellation of symptoms which result from injury to this nerve is commonly referred to as pudendal neuralgia. When conservative therapy does not provide adequate pain relief and surgical procedures fail or are not viable options, central and peripheral nerve stimulation can be effective treatment modalities. More recent approaches to treatment include the use of peripheral nerve stimulation through the use of an electrical lead placed next to the pudendal nerve in the ischioanal fossa. Also, epidural stimulation of the conus medullaris and pulsed radiofrequency ablation of the pudendal nerve have been shown to be effective in small patient populations. We present the case of a 36-year-old woman who sustained pudendal nerve injury during a hysterectomy and subsequently developed intractable pelvic pain and pudendal neuralgia. Conservative treatment measures failed, but she obtained excellent results from peripheral nerve stimulator therapy. Permanent implantation consisted of 4 tined Interstim leads, individually placed into the bilateral S3 and S4 foramina. The patient has been followed for approximately 4 years since her procedure, demonstrating increased function as she is able to stand and sit for prolonged periods of time. She has returned to her usual daily activities, including horseback riding. This is the first reported case of transforminal sacral neurostimulation providing excellent relief of pudendal neuralgia related symptoms. PMID:25247915

    Introduction: Caudal block is now- a –days a commonly used procedure for pain management and regional anaesthesia. The optimum volume of drugs required to reach the appropriate level is needed. Material and Methods: For this, we studied seventy-two human sacra and measured morphometrics like height of canal and transverse diameter. We utilized these measurements for volume estimation of sacral canal and caudal space by forming a simple mathematical formula for volume half-cone. Results: We observed that mean volumes of sacral canal and caudal space were 38.26 cm3 (23.76-62.78 cm3) and 14.25cm3 (6.67-24 cm3) respectively.Volumes of sacral canal and caudal space had higher values in males than in females. Conclusion: So, finally, it was concluded that volume of caudal space could be easily calculated this way and it was as reliable as MRI. PMID:24551603

    We describe an early reduction and percutaneous fixation technique for isolated sacral fractures. Strong manual traction combined with manual counter-traction on the torso is used to disimpact the fracture. Transcondylar traction is then applied bilaterally and two ilio-sacral screws are inserted percutaneously on each side. Open reduction and fixation, with sacral laminectomy in patients with neurological abnormalities, remains the reference standard. Early reduction and percutaneous fixation ensures restoration of the pelvic parameters while minimising soft-tissue damage and the risk of infection. Decompression procedures can be performed either during the same surgical procedure after changing the installation or after a few days. These complex fractures warrant patient referral to specialised reference centres.

    Sacral pressure ulcers (PUs) are a serious complication in frail elderly patients. Thin tissue in the sacral area, low body mass index, and anatomical location contribute to the development of sacral PUs. A comparative, descriptive study was conducted to identify patient systemic factors associated with sacral PUs and to compare survival time in patients with and without PU. All consecutive patients with PUs (n = 77) and without sacral PUs (n = 53) admitted to the skilled nursing department of a geriatric hospital in Jerusalem, Israel between July 1, 2008 and December 31, 2011 were eligible to participate. Charts of previously admitted patients were abstracted and patients were prospectively followed until discharge, death, or the end of the study. Patient demographics, comorbidities, nutritional status, physical and cognitive function (measured using the Reisberg's Functional Assessment Staging Tool [FAST], Stages of Dementia of Alzheimer Scale, and the Glasgow Coma Scale), PU status, number of courses of antibiotic treatment during admission, length of hospitalization, and mortality were compared between patients admitted with and without a sacral PU using descriptive and univariate statistics. Logistic regression models were used to estimate the odds ratio (OR) and 95% confidence intervals (CI) for sacral PU versus without PU by study covariate. The association between sacral PU and survival time was assessed using Kaplan-Meier models. Patients with a sacral PU were significantly older (average age 81.60 ±10.78 versus 77.06±11.19 years old, P = 0.02) and had a higher prevalence of dementia (70% versus 30%, P = 0.007), Parkinson's disease (92.3% versus 7.7%, P = 0.03), and anemia (67.7% versus 32.3%, P = 0.06) than patients admitted without a PU. Patients with a sacral PU also had a lower body mass index (23.1 versus 25.4, P = 0.04), and lower hemoglobin (10.54 versus 11.11, P = 0.03), albumin (26.2 versus 29.7, P = 0.002), and total protein levels (61.3 versus

  13. Abdominal aortic aneurysm.

    PubMed

    2015-04-15

    Abdominal aortic aneurysm refers to abdominal aortic dilation of 3.0 cm or greater. The main risk factors are age older than 65 years, male sex, and smoking history. Other risk factors include a family history of abdominal aortic aneurysm, coronary artery disease, hypertension, peripheral artery disease, and previous myocardial infarction. Diagnosis may be made by physical examination, an incidental finding on imaging, or ultrasonography. The U.S. Preventive Services Task Force released updated recommendations for abdominal aortic aneurysm screening in 2014. Men 65 to 75 years of age with a history of smoking should undergo one-time screening with ultrasonography based on evidence that screening will improve abdominal aortic aneurysm-related mortality in this population. Men in this age group without a history of smoking may benefit if they have other risk factors (e.g., family history of abdominal aortic aneurysm, other vascular aneurysms, coronary artery disease). There is inconclusive evidence to recommend screening for abdominal aortic aneurysm in women 65 to 75 years of age with a smoking history. Women without a smoking history should not undergo screening because the harms likely outweigh the benefits. Persons who have a stable abdominal aortic aneurysm should undergo regular surveillance or operative intervention depending on aneurysm size. Surgical intervention by open or endovascular repair is the primary option and is typically reserved for aneurysms 5.5 cm in diameter or greater. There are limited options for medical treatment beyond risk factor modification. Ruptured abdominal aortic aneurysm is a medical emergency presenting with hypotension, shooting abdominal or back pain, and a pulsatile abdominal mass. It is associated with high prehospitalization mortality. Emergent surgical intervention is indicated for a rupture but has a high operative mortality rate. PMID:25884861

    Reconstruction of the lumbosacral region after surgical excision of irradiated and recurrent spinal giant cell tumours remains a challenging problem. In this case report, we describe the use of the pedicled omentum flap in reconstruction of an irradiated and infected wide sacral defect of a 19-year-old male patient. The patient had radiotherapy and subsequent wide surgical resection after recurrence of the tumour. A myocutaneous flap from the gluteal area had failed previously. Local flap options could not be used because of the recent radiotherapy to the gluteal area. Since the patient had a laparotomy for tumour resection and a colostomy, abdominal muscles were not considered reliable for reconstructive procedures. A pedicled omentum flap was chosen as a reconstructive option because of its rich blood supply, large surface area, and angiogenic capacity. This report aims to describe the use of the pedicled omentum flap for reconstruction of the lumbosacral area following surgical resection of a spinal tumour, when gluteal and abdominal flap options for reconstruction are jeopardised.

    French physicians dealing with abdominal emergencies are not very familiar with the abdominal compartment syndrome (ACS). Increased abdominal pressure has deleterious consequences on local (intestine, liver, kidney) circulation, leading to death in the absence of correct treatment. Abdominal trauma and ruptured aortic aneurism are the main causes of ACS. Clinical presentation may be misleading: respiratory failure, oliguria or circulatory symptoms are often predominant. Abdominal palpation is inefficient for evaluating intra-abdominal pressure (IAP); only measurement of cystic pressure allows precise evaluation of IAP. Abdominal decompression is the treatment of choice. It must be performed as soon as IAP exceeds 25 mmHg. The procedure may be risky with a high incidence of severe complications when ischaemic territories are reperfused. Recent data underline the importance of compensation of hypovolemia before decompression. Abdominal closure may necessitate various techniques (aponevrotomy, Bogota bags, etc.). At any rate, IAP must remain low at the end of the procedure. In case of suspicion of ACS, early measurement of IAP is mandatory. If pressure is over 25 mmHg, a decompressive procedure must be initiated. PMID:11340703

    Dead space and poor drainage are the main reasons for intractable sacral decubitus ulcers. The objective of this study was to investigate the effects of treatment for sacral decubitus ulcer using space filling through muscle flap and closed irrigation. A total of 22 patients with serious sacral decubitus ulcer were treated with space filling through muscle flap and closed irrigation. After debridement of the decubitus ulcer, the infected areas over the bony prominence and osseous prominences were debrided. We elevated biceps femoris long head or semitendinosus and semimembranosus muscle. Pedicled by proximal part of muscle, the muscle flap was elevated to cover the ischial tuberosity. Transfusion systems of inflow and outflow drainage were placed between the muscle flap and ischial tuberosity. Wound healing and complications were observed. One wound dehiscence healed after secondary suturing. One wound gradually healed by dressing change after 3 weeks. The other cases had good results. Space filling and closed irrigation were complementary. The use of these two methods simultaneously is useful for the management of sacral decubitus ulcers.

    Tuberculosis remains one of the most common infectious diseases in the world. Vertebral tuberculosis is the commonest form of bone and joint tuberculosis; however, isolated sacral tuberculosis is rare. This atypical presentation may lead to a delay in diagnosis and treatment. We report three cases of sacral tuberculosis diagnosed in young women, aged 30, 23, and 35 years old, respectively. Lombosciatic pain was the main symptom in all cases. All patients had a biological assessment, plain radiographs, and CT scan. However, magnetic resonance imaging was done in only two cases. All patients underwent surgical sacral biopsy, and the diagnosis of tuberculosis was confirmed by histology in all cases. The evolution was satisfactory with the adjunction of antituberculous chemotherapy in all cases. Spinal tuberculosis should be the first and foremost differential diagnosis in the presence of atypical clinical and radiological features of a sacral lesion, particularly in developing countries. Early diagnosis and treatment could prevent or minimize the neurological morbidity in such cases. PMID:27708880

    Examination of 119 patients with abdominal tuberculosis permitted the description of the characteristic semiotics of the illness. Today the patients with abdominal tuberculosis are mainly women of child-bearing age with a long-term tuberculosis catamnesis and intoxication, with a history of tuberculosis of different sites, those suffering from tuberculosis or its sequels at present (64%), those with pains (94%), discomfort or swelling of the abdomen (79%), malfunction of the gastrointestinal tract (65%), weight loss (86%), malnutrition (72%), anemia (63%), not infrequently with inflammatory induration (43%) or ascites in the abdominal cavity (39%). In addition to this characteristic semiotics, the patients with abdominal tuberculosis may demonstrate the most different and unexpected symptoms up to acute abdomen (23%). To make differential diagnosis of abdominal tuberculosis, one has often to resort to diagnostic laparotomy, laparoscopy, Koch's test and to trial therapy.

    Identification of neural networks and pathways involved in activation and modulation of spinal central pattern generators (CPGs) in the absence of the descending control from the brain is important for further understanding of neural control of movement and for developing innovative therapeutic approaches to improve the mobility of spinal cord injury patients. Activation of the hindlimb innervating segments by sacrocaudal (SC) afferent input and by specific application of neurochemicals to the sacral networks is feasible in the isolated spinal cord preparation of the newborn rat. Here we review our recent studies of sacral relay neurons with lumbar projections and evaluate their role in linking the sacral and thoracolumbar (TL) networks during different motor behaviors. Our major findings show that: (1) heterogeneous groups of dorsal, intermediate and ventral sacral-neurons with ventral and lateral ascending funicular projections mediate the activation of the locomotor CPGs through sacral sensory input; and (2) rhythmic excitation of lumbar flexor motoneurons, produced by bath application of alpha-1 adrenoceptor agonists to the sacral segments is mediated exclusively by ventral clusters of sacral-neurons with lumbar projections through the ventral funiculus.

    We evaluated the relationship between stature and the length of the sacrum and coccyx using multidetector computed tomography (MDCT) and derived regression equations for stature estimation in the modern Japanese population. Two hundred and sixteen Japanese subjects (110 males and 106 females) who underwent postmortem computed tomography with subsequent forensic autopsy between January 2010 and August 2013 were measured. A sagittal-plane image of the sacrum and coccyx was used. Anterior sacral length (ASL) was defined as the linear distance from the anterosuperior edge of the first sacral vertebra (S1) to the anteroinferior edge of the fifth sacral vertebra (S5), and posterior sacral length (PSL) was defined as the linear distance from the posterosuperior edge of S1 to the anteroinferior edge of S5. Anterior sacrococcygeal length (ASCL) was defined as the linear distance from the anterosuperior edge of S1 to the anteroinferior edge of the last coccygeal vertebra (LCV), and posterior sacrococcygeal length (PSCL) was defined as the linear distance from the posterosuperior edge of S1 to the anteroinferior edge of the LCV. The correlation between stature and each parameter was evaluated by simple regression analysis using Pearson product-moment correlation coefficients. Each parameter was significantly and positively correlated with stature among both males and females. Cadaver stature (CS, cm)=0.39×PSL (mm)+123.70 [Corrected] provided the most accurate stature prediction (R=0.507, SEE=5.83 cm) in males. CS (cm)=0.56×PSCL (mm)+85.29 provided the most accurate stature prediction (R=0.659, SEE=6.68 cm) in females. We conclude that sacral/sacrococcygeal length measured with MDCT is a potentially useful tool for stature estimation, particularly in cases where better predictors such as the long bones are not available.

    The reported incidence of inflammatory abdominal aortic aneurysm (IAAA) is from 2% to 14% of patients with abdominal aortic aneurysm and the etiology of this disease is still discussed--according to the literature several pathogenic theories have been proposed. From 1992 to 1997 32 patients with IAAA were operated on. The patients were mostly symptomatic--abdominal pain was present in 68.75% cases, back pain in 31.25%, fever in 12.5% and weight loss in 6.25% of the operated patients. In all the patients ultrasound examination was performed, in 4 patients CT and in 3 cases urography. All the patients were operated on and characteristic signs of inflammatory abdominal aortic aneurysm like: thickened aortic wall, perianeurysmal infiltration or retroperitoneal fibrosis with involvement of retroperitoneal structures were found. In all cases surgery was performed using transperitoneal approach; in three cases intraoperatively contiguous abdominal organs were injured, which was connected with their involvement into periaortic inflammation. In 4 cases clamping of the aorta was done at the level of the diaphragmatic hiatus. 3 patients (9.37%) died (one patient with ruptured abdominal aortic aneurysm). Authors present diagnostic procedures and the differences in the surgical tactic, emphasizing the necessity of the surgical therapy in patients with inflammatory abdominal aortic aneurysm.

    Solitary fibrous tumors (SFTs) develop most commonly in the pleura, although they have occasionally been reported to arise in the pelvic cavity. We report a case of an SFT presenting as a painless nodule in the pelvis of a 56-year-old woman. Histologically, the tumor was composed of spindle-shaped cells arranged without pattern, with short and narrow fascicles and interspersed bundles of thick collagen, and numerous blood vessels with a focally hemangiopericytoma-like appearance. Immunohistochemically, the tumor cells strongly expressed vimentin, CD34, and bcl-2. The tumor was excised via a trans-sacral approach, without preoperative transcatheter embolization, and the patient remains well more than 2 years after her operation. To our knowledge, this is the first case of an SFT in the pelvis, which was excised completely via a trans-sacral approach.

    Lumbo-sacral chordoma is a rare, slow-growing tumor, arising from embryonic nothocordal remnants. Wide en bloc excision with clear margins remains mandatory to achieve satisfactory recurrence rates and disease-free survival. No chemotherapy has been demonstrated to be effective and radiotherapy is only marginally effective. Tyrosine kinase receptor inhibitors have showed encouraging results in locally advanced and metastatic chordoma. Reconstructive surgery may become very complex. Multidisciplinary approach in tertiary hospitals is always necessary.

    Abdominal symptoms are among the most common reasons for pediatric emergency department visits, and abdominal pain is the most frequently reported symptom. Thorough history taking and physical examination can often reach the correct diagnosis. Knowing the abdominal conditions that are most common in each age group can help radiologists narrow the differential diagnosis. When imaging tests are indicated, ultrasonography is usually the first-line technique, enabling the diagnosis or adding relevant information with the well-known advantages of this technique. Nowadays, plain-film X-ray studies are reserved for cases in which perforation, bowel obstruction, or foreign body ingestion is suspected. It is also important to remember that abdominal pain can also occur secondary to basal pneumonia. CT is reserved for specific indications and in individual cases, for example, in patients with high clinical suspicion of abdominal disease and inconclusive findings at ultrasonography. We review some of the most common conditions in pediatric emergencies, the different imaging tests indicated in each case, and the imaging signs in each condition.

    The effect of rotating the level of touhy needle to obtain successful sacral blockade was controversial. During the rotation, dural puncture was reported by some studies. In our study, we divided forty patients into two groups randomly. They all belonged to ASA I-II, receiving epidural needle insertion at L 2-3 epidural space, before epidural catheter was inserted. Total of 10 mL of 2% xylocaine was injected into the epidural space. In group A, the level of Touhy needle was pointed upward, that is, parallel to the ligament flavum. In group B, the level was pointed caudally. We determined the cutaneous extension of loss of cold sensation by using a swab of cotton wool soaked with alcohol 15 min and 25 min after the test injection. Our result showed no different in loss of cold sensation in sacral area between these two groups. So we concluded that there is no need to rotate the epidural needle for sacral blockade.

  7. Low back pain during pregnancy caused by a sacral stress fracture: a case report

    PubMed Central

    2012-01-01

    Introduction Sacral stress fractures are a rare but well known cause of low back pain. This type of fracture has also been observed as a postpartum complication. To date, no cases of intrapartum sacral stress fractures have been described in the literature. Case presentation We report the case of a 26-year-old Caucasian European primigravid patient (30 weeks and two days of gestation) who presented to our outpatient clinic with severe low back pain that had started after a downhill walk 14 days previously. She had no history of trauma. A magnetic resonance imaging scan revealed a non-displaced stress fracture of the right lateral mass of her sacrum. Following her decision to opt for non-operative treatment, our patient received an epidural catheter for pain control. The remaining course of her pregnancy was uneventful and our patient gave birth to a healthy child by normal vaginal delivery. Conclusions We conclude that a sacral stress fracture must be considered as a possible cause of low back pain during pregnancy. PMID:22475388

    Sacral neuromodulation is a new treatment for urinary and fecal incontinence that has demonstrated good therapeutic results. This treatment modality has shown not only to reduce urinary dysfunction symptoms and urinary and fecal incontinence but improve quality of life scores as well. We present a 73 years old female patient with severe fecal and urinary incontinence with major quality of life impact. She was referred after failure of different surgical and conservative therapeutic approaches. Her evaluation met inclusion criteria for sacral neuromodulation treatment. Acute sacral nerve evaluation (PNE) proved to be therapeutic in the patient as measured by at least a 50 percent improvement in her symptoms so a permanent implant (Medtronic InterStim System) was placed. After the implant there was a significant improvement in urinary and fecal functional scores. Fecal Incontinence Severity Index improved from 34 to 8 and Urinary Sandvik's Severity Index from very severe urinary incontinence to minor urinary incontinence after the placement of the implant. Using standard quality of life questionnaires, she improved in the areas of lifestyle,coping and behavior and her experience with depression and self-perception.

    Achieving complete resolution of spinal hydatid cyst disease is quite challenging when bone is involved. Many authors reported the poor outcome of posterior decompression and laminectomy for intraosseous spinal hydatid disease. In an attempt to avoid a similar poor outcome, hydatid cysts were reached via both anterior and posterior surgical approaches in our patient. A 73-year-old man presented with complaints of low back and right leg pain. Symptoms or signs of systemic hydatid cyst disease were absent. MRI demonstrated a cystic lesion in the presacral/retroperitoneal region, involving the body of the sacrum and sacral canal. Computed tomography images showed enlargement of the sacral foraminae. The multiseptated cysts and their contents were isodense with cerebrospinal fluid. The cysts were removed via an anterior extraperitoneal approach, using a paramedian vertical incision, and then were also approached posteriorly via bilateral S1 hemilaminectomy. No neurological deficits occurred following surgery. The patient's symptoms completely disappeared after this combination of aggressive surgery and antihelminthic therapy. The application of both anterior and posterior approaches to intraosseous sacral hydatid cysts may be preferred when faced with hydatid disease in this location.

    The abdominal actinomycosis (AA) is a rare and often unrecognised suppurative chronic illness. It is caused by an anaerobic Gram positive bacteria, Actinomyces israelii. Abdominal actinomycosis is responsible for pseudotumoral syndrome often leading, to a large and mutilating surgery whereas a prolonged treatment by antibiotics would have permitted to cure the disease. The diagnosis is obtained generally from anatomopathologic exam. We report four cases of abdominal actinomycosis being revealed by a pseudotumoral syndrome. The diagnosis was only made after surgery. In spite of an active treatment by antibiotics during several months, two of our patients had a relapse of the infectious process. These four observations confirm the diagnostic and therapeutic difficulties previously reported by other authors.

  11. The Acute Abdominal Aorta.

    2015-11-01

    Acute disorders of the abdominal aorta are potentially lethal conditions that require prompt evaluation and treatment. Computed tomography (CT) is the primary imaging method for evaluating these conditions because of its availability and speed. Volumetric CT acquisition with multiplanar reconstruction and three-dimensional analysis is now the standard technique for evaluating the aorta. MR imaging may be useful for select applications in stable patients in whom rupture has been excluded. Imaging is indispensable for diagnosis and treatment planning, because management has shifted toward endoluminal repair. Acute abdominal aortic conditions most commonly are complications of aneurysms and atherosclerosis. PMID:26526434

    Background Sacral nerve stimulation is a therapeutic option with demonstrated efficacy for conditions presenting with perineal pain caused by different etiologies. We aimed to assess whether a sacral electrode (InterStim®, Medtronic, Minneapolis, MN, USA) inserted through the caudal pathway is able to offer an acceptable level of sacral stimulation and rate of catheter migration. Methods We present 12 patients with pelvic pain who received sacral neuromodulation via the sacral hiatus with the InterStim electrode. We evaluated patient satisfaction as well as migration and removal of the electrode, if necessary. Results Our experience included 12 patients, 10 women and two men, with a mean age of 60 years. In eight of the 12 patients, the initial therapy was effective, and the final system implantation was performed. During subsequent follow-up, patient satisfaction was good. To date, there have been no cases of electrode displacement or migration. Conclusions The caudal insertion of the InterStim electrode, with its own fixation system, and initially designed for transsacral insertion, appears in our experience to be a satisfactory option which can minimize electrode displacements, achieving similar results in therapeutic efficacy and causing no difficulties in removal.

    Sacral chordoma is a rare spine tumor with a high recurrence rate even after optimal therapy. Previous studies have demonstrated that the PI3K/AKT pathway plays a pivotal role in chordoma, and high expression of pAKT is associated with poor prognosis. Recently, PHLPP was recognized to be a tumor suppressor that targets AKT. We analyzed the expression of PHLPP1 and AKT2 in 37 chordoma samples and 11 fetal nucleus pulposus samples by immunohistochemical staining. Of the chordoma cases, 40.5% (15/37) showed strong cytoplasmic staining (score ≥3) for PHLPP1, which was significantly lower than the 90.9% (10/11) of fetal nucleus pulposus samples (P = 0.004). Conversely, strong immunohistochemical staining for AKT2 was observed in 75.7% (28/37) of chordoma samples, which was significantly higher than 36.4% (4/11) of fetal nucleus pulposus (P = 0.021). Kaplan-Meier survival curves and log-rank test showed that patients with high expression of PHLPP1 experienced longer progression free survival time than those with low PHLPP1 expression (P = 0.011). Further multivariate Cox regression analysis indicated that PHLPP1 expression level and surgical approaches were independent risk factors for chordoma recurrence (P = 0.023 and P = 0.022). However, PHLPP1 expression was not statistically related to patients’ total survival time. Conclusively, our results suggest that PHLPP1 plays a crucial role in sacral chordoma, and may be a promising biomarker for prognosis. Meanwhile, manipulation of PHLPP1 expression is also a potential therapeutic approach for the treatment of sacral chordoma. PMID:26823799

  16. Lateral Abdominal Wall Reconstruction

    PubMed Central

    Baumann, Donald P.; Butler, Charles E.

    2012-01-01

    Lateral abdominal wall (LAW) defects can manifest as a flank hernias, myofascial laxity/bulges, or full-thickness defects. These defects are quite different from those in the anterior abdominal wall defects and the complexity and limited surgical options make repairing the LAW a challenge for the reconstructive surgeon. LAW reconstruction requires an understanding of the anatomy, physiologic forces, and the impact of deinnervation injury to design and perform successful reconstructions of hernia, bulge, and full-thickness defects. Reconstructive strategies must be tailored to address the inguinal ligament, retroperitoneum, chest wall, and diaphragm. Operative technique must focus on stabilization of the LAW to nonyielding points of fixation at the anatomic borders of the LAW far beyond the musculofascial borders of the defect itself. Thus, hernias, bulges, and full-thickness defects are approached in a similar fashion. Mesh reinforcement is uniformly required in lateral abdominal wall reconstruction. Inlay mesh placement with overlying myofascial coverage is preferred as a first-line option as is the case in anterior abdominal wall reconstruction. However, interposition bridging repairs are often performed as the surrounding myofascial tissue precludes a dual layered closure. The decision to place bioprosthetic or prosthetic mesh depends on surgeon preference, patient comorbidities, and clinical factors of the repair. Regardless of mesh type, the overlying soft tissue must provide stable cutaneous coverage and obliteration of dead space. In cases where the fasciocutaneous flaps surrounding the defect are inadequate for closure, regional pedicled flaps or free flaps are recruited to achieve stable soft tissue coverage. PMID:23372458

    Antiphospholipid syndrome (APS) is characterised by recurrent arterial and/or venous thromboses and recurrent late miscarriages in the presence of antiphospholipid antibodies, and can be a hugely debilitating disorder. While the commonest thrombotic manifestations of this condition such as deep vein thrombosis and stroke are well documented, there has been increasing recognition of numerous less common complications in most organ systems. We present a female patient with APS and a lupus-like illness who had atraumatic sacral fractures as well as multiple spontaneous fractures affecting her ribs and the metatarsals in both her feet.

    Sacral nerve stimulation (SNS) was originally developed in the field of urinary incontinence. Without adaptation, it was subsequently applied to treat faecal incontinence. SNS has now become a first line therapy for this socially disabling condition, however the mechanism of action is unknown. This review examines the evidence for stimulation parameters currently used for SNS in humans and considers the potential electrophysiological effects of changing these parameters. However, without a proper understanding of the physiology of SNS, changing stimulation parameters remains empirical. PMID:25623489

    2016-01-01

    Summary: Sacral fractures that result in spinopelvic dissociation are unstable injuries that are often treated surgically, with iliosacral screw fixation and/or lumbopelvic fixation from L4 to the pelvis. Open lumbopelvic fixation allows for direct fracture reduction and immediate postoperative weight bearing, but is associated with a relatively high wound complication rate. Open surgery often takes several hours and can be associated with significant blood loss, and therefore may not be well tolerated physiologically in these patients who often have multiple injuries. We developed a percutaneous lumbopelvic reduction and fixation technique to address these issues. PMID:26894767

    Over the past several years, abdominal single photon emission computed tomography (SPECT) imaging has evolved from a research tool to an important clinical imaging modality that is helpful in the diagnostic assessment of a wide variety of disorders involving the abdominal viscera. Although liver-spleen imaging is the most popular of the abdominal SPECT procedures, blood pool imaging is becoming much more widely utilized for the evaluation of cavernous hemangiomas of the liver as well as other vascular abnormalities in the abdomen. Adjunctive indium leukocyte and gallium SPECT studies are also proving to be of value in the assessment of a variety of infectious and neoplastic diseases. As more experience is acquired in this area, SPECT should become the primary imaging modality for both gallium and indium white blood cells in many institutions. Renal SPECT, on the other hand, has only recently been used as a clinical imaging modality for the assessment of such parameters as renal depth and volume. The exact role of renal SPECT as a clinical tool is, therefore, yet to be determined. 79 references.

  1. Abdominal emergencies during pregnancy.

    Abdominal emergencies during pregnancy (excluding obstetrical emergencies) occur in one out of 500-700 pregnancies and may involve gastrointestinal, gynecologic, urologic, vascular and traumatic etiologies; surgery is necessary in 0.2-2% of cases. Since these emergencies are relatively rare, patients should be referred to specialized centers where surgical, obstetrical and neonatal cares are available, particularly because surgical intervention increases the risk of premature labor. Clinical presentations may be atypical and misleading because of pregnancy-associated anatomical and physiologic alterations, which often result in diagnostic uncertainty and therapeutic delay with increased risks of maternal and infant morbidity. The most common abdominal emergencies are acute appendicitis (best treated by laparoscopic appendectomy), acute calculous cholecystitis (best treated by laparoscopic cholecystectomy from the first trimester through the early part of the third trimester) and intestinal obstruction (where medical treatment is the first-line approach, just as in the non-pregnant patient). Acute pancreatitis is rare, usually resulting from trans-ampullary passage of gallstones; it usually resolves with medical treatment but an elevated risk of recurrent episodes justifies laparoscopic cholecystectomy in the 2nd trimester and endoscopic sphincterotomy in the 3rd trimester. The aim of the present work is to review pregnancy-induced anatomical and physiological modifications, to describe the main abdominal emergencies during pregnancy, their specific features and their diagnostic and therapeutic management.

    Introduction Ostriches typically avoid humans in the wild, since they correctly assess humans as potential predators, and, if approached, often run away. However, ostriches may turn aggressive rather than run when threatened, especially when cornered, and may also attack when they feel the need to defend their offspring or territories. Presentation of case A 71-year-old male patient presented with intra abdominal injury sustained from being kicked in the abdominal wall by an ostrich. During laparotomy, were found free peritoneal effusion and perforation of the small intestine. Discussion The clinical history and physical examination are extremely important for diagnostic and therapeutic decision making. CT-scan is the most accurate exam for making diagnosis. Surgery is the treatment of choice, and is always indicated when there is injury to the hollow viscera. In general it is possible to suture the defect. Conclusion In cases of blunt abdominal trauma by animals is necessary to have a low threshold of suspicion for acute abdomen. PMID:25685344

  3. Colonization of the murine hindgut by sacral crest-derived neural precursors: experimental support for an evolutionarily conserved model.

    PubMed

    Kapur, R P

    2000-11-01

    Enteric ganglia in the hindgut are derived from separate vagal and sacral neural crest populations. Two conflicting models, based primarily on avian data, have been proposed to describe the contribution of sacral neural crest cells. One hypothesizes early colonization of the hindgut shortly after neurulation, and the other states that sacral crest cells reside transiently in the extraenteric ganglion of Remak and colonize the hindgut much later, after vagal crest-derived neural precursors arrive. In this study, I show that Wnt1-lacZ-transgene expression, an "early" marker of murine neural crest cells, is inconsistent with the "early-colonization" model. Although Wnt1-lacZ-positive sacral crest cells populate pelvic ganglia in the mesenchyme surrounding the hindgut, they are not found in the gut prior to the arrival of vagal crest cells. Similarly, segments of murine hindgut harvested prior to the arrival of vagal crest cells and grafted under the renal capsule fail to develop enteric neurons, unless adjacent pelvic mesenchyme is included in the graft. When pelvic mesenchyme from DbetaH-nlacZ transgenic embryos is apposed with nontransgenic hindgut, neural precursors from the mesenchyme colonize the hindgut and form intramural ganglion cells that express the transgenic marker. Contribution of sacral crest-derived cells to the enteric nervous system is not affected by cocolonization of grafts by vagal crest-derived neuroglial precursors. The findings complement recent studies of avian chimeras and support an evolutionarily conserved model in which sacral crest cells first colonize the extramural ganglion and secondarily enter the hindgut mesenchyme.

    Sacral agenesis (SA) is a rare condition consisting of the imperfect development of any part of the sacrum. This paper describes two cases of the rare cooccurrence of ipsilateral SA and developmental dysplasia of the hip (DDH) and analyzes possible contributory factors for SA and DDH. Each of a 16-year-old female and 13-year-old female visited our hospital for left hip pain and limping. The findings of physical examinations showed a lower limb length discrepancy (left side) in both cases, as well as left hip pain without limitations of the range of motion or neurological deficits. Initial radiographs demonstrated left subluxation of the left hip with associated acetabular dysplasia and partial left sacral agenesis. MRI revealed a tethering cord with a fatty filum terminale, and periacetabular osteotomy combined with allogeneic bone grafting was performed. After the surgery, the patients experienced no further pain, with no leg length discrepancy and were able to walk without a limp, being neurologically normal with a normal left hip range of motion. The cooccurrence of SA and DDH suggests a plausible hypothesis to explain the embryogenic relationship between malformation of the sacrum and hip. PMID:25737792

    The current report presents a case of a 78-year-old male with sacral chordoma, showing an aggressive clinical course. The patient underwent sacral resection, however, nine months later, multiple metastases were detected by magnetic resonance imaging. The metastases progressed rapidly and 15 months following surgery the patient succumbed to respiratory dysfunction. An autopsy revealed multiple metastases of the lung, liver, heart, kidneys and vertebrae. Pathologically, the tumors did not show proliferation of anaplastic cells or dedifferentiation; however, the metastatic tumor cells were smaller than the primary tumor cells. The Ki-67 labeling indices were <5% in all of the patient’s tumors, therefore, the capacity for cellular proliferation of the tumors was considered to be low. Chordoma in adults are generally slow-growing tumors and are associated with a relatively prolonged course and frequent local recurrences. Therefore, it must be recognized that chordoma may grow rapidly and show an aggressive clinical course, even when the Ki-67 labeling index is low. PMID:24765153

    The sacral area is the most common site of pressure sore in bed-ridden patients. Though many treatment methods have been proposed, a musculocutaneous flap using the gluteus muscles or a fasciocutaneous flap is the most popular surgical option. Here, we propose a new method that combines the benefits of these 2 methods: combined V-Y fasciocutaneous advancement and gluteus maximus muscle rotational flaps. A retrospective review was performed for 13 patients who underwent this new procedure from March 2011 to December 2013. Patients' age, sex, accompanying diseases, follow-up duration, surgical details, complications, and recurrence were documented. Computed tomography was performed postoperatively at 2 to 4 weeks and again at 4 to 6 months to identify the thickness and volume of the rotational muscle portion. After surgery, all patients healed within 1 month; 3 patients experienced minor complications. The average follow-up period was 13.6 months, during which time 1 patient had a recurrence (recurrence rate, 7.7%). Average thickness of the rotated muscle was 9.43 mm at 2 to 4 weeks postoperatively and 9.22 mm at 4 to 6 months postoperatively (p = 0.087). Muscle thickness had not decreased, and muscle volume was relatively maintained. This modified method is relatively simple and easy for reconstructing sacral sores, provides sufficient padding, and has little muscle donor-site morbidity. PMID:27366755

    Only few cases with sacral radiculitis due to infection with Borrelia burgdorferi leading to neurogenic urinary dysfunction have been reported. A 57-year-old male developed urethral pain and urinary retention, requiring permanent catheterization. Extensive urological investigations did not reveal a specific cause, which was why neurogenic bladder dysfunction was suspected. Neurologic exam revealed only mildly reduced tendon reflexes. Cerebral and spinal MRI were noninformative. CSF investigations, however, revealed pleocytosis, elevated protein, and antibodies against Borrelia burgdorferi. Intravenous ceftriaxone for three weeks resulted in immediate improvement of bladder dysfunction, with continuous decline of residual urine volume and continuous increase of spontaneous urine volume even after removal of the catheter and initiation of self-catheterization. Sacral radiculitis due to infection with Borrelia burgdorferi is a potential cause of detrusor areflexia and urethral, perineal, inguinal, and scrotal pain and may be misinterpreted as cystitis or urethritis. Ceftriaxone may result in progressive recovery of bladder dysfunction and pain. Neuroborreliosis may manifest exclusively as neurourological problem. PMID:26664404

    The locking compression plate fixation treatment for the unstable sacral fractures is simple and effective, with less trauma and complications. Some locking compression plate parts have been made of high-strength Plate manufactured by hot stamping process since the demand for lightweight biomedical materials. Finite Element (FE) method of One-Step inverse forming based on deformation theory is the tool to evaluate the formability of locking compression plate panel quickly in initial design for reducing costs and development cycle of Plate. But current one-step inverse forming methods are all suitable for cold stamping, not hot-stamping. This paper proposed one-step inverse forming method and workflow for hot-stamping of locking compression Plate. And the B pillar of a sacral bone was simulated and its computing result was compared with experimental value. The result shows that the proposed method in this paper can quickly evaluate high temperature formability of high-strength Plate. And the method is proposed to be used in initial design.

    Delayed or non-union of a sacral fracture is a serious clinical condition that may include chronic pain, sitting discomfort, gait disturbances, neurological problems, and inability to work. It is also a difficult reconstruction problem. Late correction of the deformity is technically more demanding than the primary treatment of acute pelvic injuries. Open reduction, internal fixation (ORIF), excision of scar tissue, and bone grafting often in a multi-step approach are considered to be the treatment of choice in delayed unions of the pelvic ring. This procedure implies the risk of neurological and vascular injuries, infection, repeated failure of union, incomplete correction of the deformity, and incomplete pain relief as the most important complications. We report a new approach for minimally invasive treatment of a delayed union of the sacrum without vertical displacement. A patient who suffered a Malgaigne fracture (Tile C1.3) was initially treated with closed reduction and percutaneous screw fixation (CRPF) of the posterior pelvic ring under CT navigation and plating of the anterior pelvic ring. Three months after surgery he presented with increasing hip pain caused by a delayed union of the sacral fracture. The lesion was successfully treated percutaneously in a single step procedure using CT navigation for drilling of the delayed union, autologous bone grafting, and screw fixation.

    A case of leaking mycotic abdominal aortic aneurysm is reported, with a brief review of the literature. A 58 year old female presented with shoulder and abdominal pain associated with diarrhoea, vomiting and fever with leucocytosis. Computed tomography of the abdomen showed pooling of contrast in the retroperitoneum anterior to a non-dilated abdominal aorta. There was considerable retroperitoneal blood accumulating in a mass-like lesion in the right lower abdomen and pelvis obstructing the right renal collecting system. Laparotomy revealed a 4 cm diameter saccular aneurysm of the abdominal aorta, with a 1 cm diameter neck. Culture of the thrombus grew Streptococcus pyogenes. PMID:7993259

    Chronic abdominal pain is a common pediatric condition affecting 20% of the pediatric population worldwide. Most children with this disorder are found to have no specific organic etiology and are given the diagnosis of functional abdominal pain. Well-designed clinical trials have found hypnotherapy and guided imagery to be the most efficacious treatments for this condition. Hypnotic techniques used for other somatic symptoms are easily adaptable for use with functional abdominal pain. The author discusses 2 contrasting hypnotic approaches to functional abdominal pain and provides implications for further research. These approaches may provide new insights into this common and complex disorder. PMID:21922712

    Objective: The objective of this review is to evaluate the efficacy and safety of sacral neuromodulation in treating chronic pelvic pain related to Painful bladder syndrome/Interstitial-cystitis. Design: The databases searched were MEDLINE and EMBASE [1950- Nov 2011]. Additional searches were performed on the Cochrane Database of Systematic reviews (CDSR), Scopus, CINAHL, BIOSIS, The Cochrane controlled trials register, the science citation index, TRIP DATABASE. Results: Overall 70.8% or 170/244 patients were successful at the trial stage. The only randomized controlled trial reported a decrease in Visual analogue pain scores of 49% (7.9 to 4.0) for sacral nerve stimulation [SNS] and 29%(4.5 to 3.2) for pudendal nerve stimulation [PNS] at 6 months follow up. Nine observational studies reported a decrease in pain scores/decrease in pain medications at long term follow up following permanent sacral neuromodulation. One study showed an 80% improvement in Global response assessment score. Conclusion: The results from the randomised controlled trial and case series/case reports demonstrate a reduction of pain symptoms of Painful bladder syndrome following sacral neuromodulation PMID:23225919

    A marfanoid patient underwent celiotomy for a pelvic mass and was found to have an anterior sacral meningocele. Nine years prior to that time she had undergone surgery because of a "sacrococcygeal cyst," which in retrospect seemed to be a posterior meningocele. The preoperative diagnosis of meningocele is important to successful treatment.

    Sacral giant cell tumors are rare neoplasms, histologically benign but potentially very aggressive due to the difficulty in achieving a complete resection, their high recurrence rate, and metastization capability. Although many treatment options have been proposed, en bloc excision with tumor-free margins seems to be the most effective, being associated with long term tumor control, improved outcome, and potential cure. An exemplifying case of a 29-year-old female with progressive complaints of pain and paresthesias in the sacral and perianal regions, constipation, and weight loss for 6 months is presented. The surgical technique for en bloc excision of a large sacral giant cell tumor through a modified Kraske procedure with mid-sacrectomy and coccygectomy is described. Complete resection with wide tumor-free margins was achieved. At 5 years of follow-up the patient is neurologically intact, without evidence of local recurrence on imaging studies. A multidisciplinary surgical procedure is mandatory to completely remove sacral tumors. In the particular case of giant cell tumors, it allows minimizing local recurrence preserving neurovascular function, through a single dorsal and definitive approach. PMID:25386379

    Appropriate access to the abdominal cavity is the first and crucial step for successful abdominal surgical intervention. In planning the incision, several variables have to be considered, such as anatomy of the abdominal wall, localization of the target organ, and individual conditions (previous incisions, minimal access surgery, etc). Medial laparotomy is the preferred incision for emergency cases and ill-defined pathologies, allowing access and hence exploration to all quadrants. Transverse laparotomies give superior access to the dorsal and right aspects of the liver and cause less pain in patients unfit for regional anesthetic procedures. Draining of the abdominal cavity is used after various resective and reconstructive procedures, but there is little evidence for its use in a number of operations such as gastric, hepatic, and colorectal resections. Advantages and disadvantages of different abdominal wall incisions and drainages are discussed.

    The skin between the mastectomy scar and the future infra-mammary fold may be managed in different ways in delayed breast reconstruction using a DIEP (deep inferior epigastric perforator). Conserving this skin and positioning the flap skin paddle in the middle of the breast usually highlights skin color disparity because of two visible transition zones. Resection of the entire skin under the scar may be more aesthetic but limits direct closure possibility in case of flap failure. In order to benefit from both aesthetic result and safe surgical method, we propose the abdominal drop flap. The inferior thoracic skin flap is detached from the thoracic wall beyond the future infra-mammary fold, preserved and pushed under the breast.

    Since receiving approval from the US Food and Drug Administration in 1997, sacral neuromodulation (SNM) has become the recommended treatment of urinary urge incontinence, urgency-frequency, nonobstructive urinary retention, and fecal incontinence. The manufacturer has introduced different technical modifications while surgeons and researchers have adapted and published various innovations and alterations of the technique. This review summarizes the current knowledge and recommendations of SNM preoperative decision making, the implantation technique, and available programming parameters and algorithms based on MEDLINE research, manufacturer instructions, and the approach of an experienced neurourological team. The primary steps and technical aspects to optimize SNM efficacy were the introduction of the tined-lead electrode and the development of the InterStim II impulse generator (both developed by Medtronic, Inc., Minneapolis, MN). The initiation of the staged implantation technique for sequential evaluation and implantation with the definitive quadripolar electrode completes the treatment algorithm so that an increased responder rate of SNM for all indications can be achieved.

    When a patient presents with acute voiding dysfunction without a typical skin rash, it may be difficult to make a diagnosis of herpes zoster. Here, we present a case of scrub typhus in a 25-year-old man with the complication of urinary dysfunction. The patient complained of loss of urinary voiding sensation and constipation. After eight days, he had typical herpes zoster eruptions on the sacral dermatomes and hypalgesia of the S1-S5 dermatomes. No cases of dual infection with varicella zoster virus and Orientia tsutsugamushi were found in the literature. In the described case, scrub typhus probably induced sufficient stress to reactivate the varicella zoster virus. Early recognition of this problem is imperative for prompt and appropriate management, as misdiagnosis can lead to long-term urinary dysfunction. It is important that a diagnosis of herpes zoster be considered, especially in patients with sudden onset urinary retention.

The procedure was followed by a wide decompressive laminectomy. The patient had a progressive improvement of the symptoms which gradually disappeared in 12 mo. The radiograph at 6 and 12 mo showed complete fusion system. The choice of treatment in L5-S1 ontogenetic spondylolithesis is related to a correct clinical and diagnostic planning (X-ray, computer tomography magnetic resonance imaging, Measurement). In particular, the severity index and the square of unstable zone, and the standard measurements already described in the literature, are important to understand and to plane the correct surgical strategy, that require, in most of the times, fusion and interbody artrodesis.

    Anterior sacral meningoceles (ASMs) are rare defects in the sacrum with thecal sac herniations and symptoms that commonly include constipation, dysmenorrhea, and urinary disturbances. An ASM causing hydronephrosis and acute renal failure from compression of the lower portion of the urinary tract is a rare clinical entity. Only one other case has been reported. The authors present the case of a 37-year-old man admitted for obstructive renal failure and hydronephrosis due to a giant ASM that measured 25 × 12 × 18 cm and compressed the ureters and bladder. The ASM was successfully treated via an anterior transabdominal approach in which the authors used a novel technique for watertight closure of the meningocele pedicle with an endoscopic cutting stapler. The authors review the literature and discuss the surgical options for the treatment of ASMs, specifically the management of ASMs in the context of obstructive renal failure and hydronephrosis.

    Purpose A sacral chordoma is a rare, slow-growing, primary bone tumor, arising from embryonic notochordal remnants. Radical surgery is the only hope for cure. The aim of our present study is to analyse our experience with the challenging treatment of this rare tumor, to review current treatment modalities and to assess the outcome based on R status. Methods Eight patients were treated in our institution between 2001 and 2011. All patients were discussed by a multidisciplinary tumor board, and an en bloc surgical resection by posterior perineal access only or by combined anterior/posterior accesses was planned based on tumor extension. Results Seven patients underwent radical surgery, and one was treated by using local cryotherapy alone due to low performance status. Three misdiagnosed patients had primary surgery at another hospital with R1 margins. Reresection margins in our institution were R1 in two and R0 in one, and all three recurred. Four patients were primarily operated on at our institution and had en bloc surgery with R0 resection margins. One had local recurrence after 18 months. The overall morbidity rate was 86% (6/7 patients) and was mostly related to the perineal wound. Overall, 3 out of 7 resected patients were disease-free at a median follow-up of 2.9 years (range, 1.6-8.0 years). Conclusion Our experience confirms the importance of early correct diagnosis and of an R0 resection for a sacral chordoma invading pelvic structures. It is a rare disease that requires a challenging multidisciplinary treatment, which should ideally be performed in a tertiary referral center. PMID:24999463

  6. Axons of sacral preganglionic neurons in the cat: II. Axon collaterals.

    2001-01-01

    Axon collaterals were identified in 21 of 24 preganglionic neurons in the lateral band of the sacral parasympathetic nucleus of the cat. Following the intracellular injection of HRP or neurobiotin the axons from 20 of these neurons were followed and 53 primary axon collaterals were found to originate from unmyelinated segments and from nodes of Ranvier. Detailed mapping done in the five best labeled cells showed bilateral axon collaterals distributions up to 25,000 microm in length with 950 varicosities and unilateral distributions up to 12,561 microm with 491 varicosities. The axon collaterals appeared to be unmyelinated, which was confirmed at EM, and were small in diameter (average 0.3 microm). Varicosities were located mostly in laminae I, V, VII, VIII and X and in the lateral funiculi. Most varicosities were not in contact with visible structures but some were seen in close apposition to Nissl stained somata and proximal dendrites. Varicosities had average minor diameters of 1.3 microm and major diameters of 2.3 microm. Most were boutons en passant while 10-20% were boutons termineaux. EM revealed axodendritic and axoaxonic synapses formed by varicosities and by the axons between varicosities. It is estimated that the most extensive of these axon collaterals systems may contact over 200 spinal neurons in multiple locations. These data lead to the conclusion that sacral preganglionic neurons have multiple functions within the spinal cord in addition to serving their target organ. As most preganglionic neurons in this location innervate the urinary bladder, it is possible that bladder preganglionic neurons have multiple functions.

    Purpose: To evaluate the efficacy, post-treatment function, toxicity, and complications of carbon ion radiotherapy (RT) for sacral chordoma compared with surgery. Methods and Materials: The records of 17 primary sacral chordoma patients treated since 1990 with surgery (n = 10) or carbon ion RT (n = 7) were retrospectively analyzed for disease-specific survival, local recurrence-free survival, complications, and functional outcome. The applied carbon ion dose ranged from 54.0 Gray equivalent (GyE) to 73.6 GyE (median 70.4). Results: The mean age at treatment was 55 years for the surgery group and 65 years for the carbon ion RT group. The median duration of follow-up was 76 months for the surgery group and 49 months for the carbon ion RT group. The local recurrence-free survival rate at 5 years was 62.5% for the surgery and 100% for the carbon ion RT group, and the disease-specific survival rate at 5 years was 85.7% and 53.3%, respectively. Urinary-anorectal function worsened in 6 patients (60%) in the surgery group, but it was unchanged in all the patients who had undergone carbon ion RT. Postoperative wound complications requiring reoperation occurred in 3 patients (30%) after surgery and in 1 patient (14%) after carbon ion RT. The functional outcome evaluated using the Musculoskeletal Tumor Society scoring system revealed 55% in the surgery group and 75% in the carbon ion RT group. Of the six factors in this scoring system, the carbon ion RT group had significantly greater scores in emotional acceptance than did the surgery group. Conclusion: Carbon ion RT results in a high local control rate and preservation of urinary-anorectal function compared with surgery.

    Relatively little is known about the organization of neural input to pelvic viscera in amphibia. In this study, sacral spinal efferent neurons were labeled in Xenopus laevis frogs by application of horseradish peroxidase (HRP) to the tenth spinal nerve, to pelvic musculature, or to the pelvic nerve. DiI was applied to the pelvic nerve with similar results. Labeled spinal neurons were located in the intermediate gray or in the ventral horn. Neurons in the tenth dorsal root ganglion, but not in the spinal cord, were labeled after application of HRP or DiI to the pudendal nerve. The labeled neurons in the spinal cord intermediate gray were in a position comparable to that of the mammalian sacral parasympathetic nucleus (SPN). Two apparent subdivisions included 1) a medial cluster of cells with mediolaterally oriented dendrites and 2) a lateral group with dorsoventrally oriented dendrites. An intermediate group, not clearly classed with the other two, was also identifiable. In some cases, labeled tenth nerve primary afferents were seen in contact with efferent neurons of the intermediate gray. Labeled neurons in the ventral horn medial to the lateral motor column were small, with dendrites oriented mediolaterally, in a position comparable to that of the mammalian Onuf's nucleus. The peripheral targets of DiI-labeled pelvic nerve axons were the compressor cloaca muscle, cloaca, and bladder. DiI-labeled pudendal nerve axons distributed peripherally to cloacal lip and medial thigh integument. These data suggest that the pudendal nerve in amphibians is purely sensory and that both somatic and autonomic motor axons traverse the pelvic nerve.

    Purpose: Develop an IMRT planning technique that can preferentially spare sacral bone marrow for pelvic cancer patients. Methods: Six pelvic cancer patients (two each with anal, cervical, and rectal cancer) were enrolled in an IRB approved protocol to obtain FLT PET images at simulation, during, and post chemoradiation therapy. Initially, conventional IMRT plans were created to maintain target coverage and reduce dose to OARs such as bladder, bowel, rectum, and femoral heads. Simulation FLT PET images were used to create IMRT plans to spare bone marrow identified as regions with SUV of 2 or greater (IMRT-BMS) within the pelvic bones from top of L3 to 5mm below the greater trochanter without compromising PTV coverage or OAR sparing when compared to the initial IMRT plan. IMRT-BMS plans used 8–10 beam angles that surrounded the subject. These plans were used for treatment. Retrospectively, the same simulation FLT PET images were used to create IMRT plans that spared bone marrow located in the sacral pelvic bone region (IMRT-FAN) also without compromising PTV coverage or OAR sparing. IMRT-FAN plans used 16 beam angles every 12° anteriorly from 90° – 270°. Optimization objectives for the sacral bone marrow avoidance region were weighted to reduce ≥V10. Results: IMRT-FAN reduced dose to the sacral bone marrow for all six subjects. The average V5, V10, V20, and V30 differences from the IMRT-BMS plan were −2.2 ± 1.7%, −11.4 ± 3.6%, −17.6 ± 5.1%, and −19.1 ± 8.1% respectively. Average PTV coverage change was 0.5% ± 0.8% from the conventional IMRT plan. Conclusion: An IMRT planning technique that uses beams from the anterior and lateral directions reduced the volume of sacral bone marrow that receives ≤10Gy while maintaining PTV coverage and OAR sparing. Additionally, the volume of sacral bone marrow that received 20 or 30 Gy was also reduced.

    Background Sacral neuromodulation has become a well-established and widely accepted treatment for refractory non-neurogenic lower urinary tract dysfunction, but its value in patients with a neurological cause is unclear. Although there is evidence indicating that sacral neuromodulation may be effective and safe for treating neurogenic lower urinary tract dysfunction, the number of investigated patients is low and there is a lack of randomized controlled trials. Methods and design This study is a prospective, randomized, placebo-controlled, double-blind multicenter trial including 4 sacral neuromodulation referral centers in Switzerland. Patients with refractory neurogenic lower urinary tract dysfunction are enrolled. After minimally invasive bilateral tined lead placement into the sacral foramina S3 and/or S4, patients undergo prolonged sacral neuromodulation testing for 3–6 weeks. In case of successful (defined as improvement of at least 50% in key bladder diary variables (i.e. number of voids and/or number of leakages, post void residual) compared to baseline values) prolonged sacral neuromodulation testing, the neuromodulator is implanted in the upper buttock. After a 2 months post-implantation phase when the neuromodulator is turned ON to optimize the effectiveness of neuromodulation using sub-sensory threshold stimulation, the patients are randomized in a 1:1 allocation in sacral neuromodulation ON or OFF. At the end of the 2 months double-blind sacral neuromodulation phase, the patients have a neuro-urological re-evaluation, unblinding takes place, and the neuromodulator is turned ON in all patients. The primary outcome measure is success of sacral neuromodulation, secondary outcome measures are adverse events, urodynamic parameters, questionnaires, and costs of sacral neuromodulation. Discussion It is of utmost importance to know whether the minimally invasive and completely reversible sacral neuromodulation would be a valuable treatment option for

    The management of patients with penetrating abdominal trauma is outlined in Figure 1. Patients with hemodynamic instability, evisceration, significant gastrointestinal bleeding, peritoneal signs, gunshot wounds with peritoneal violation, and type 2 and 3 shotgun wounds should undergo emergency laparotomy. The initial ED management of these patients includes airway management, monitoring of cardiac rhythm and vital signs, history, physical examination, and placement of intravenous lines. Blood should be obtained for initial hematocrit, type and cross-matching, electrolytes, and an alcohol level or drug screen as needed. Initial resuscitation should utilize crystalloid fluid replacement. If more than 2 liters of crystalloid are needed to stabilize an adult (less in a child), blood should be given. Group O Rh-negative packed red blood cells should be immediately available for a patient in impending arrest or massive hemorrhage. Type-specific blood should be available within 15 minutes. A patient with penetrating thoracic and high abdominal trauma should receive a portable chest x-ray, and a hemo- or pneumothorax should be treated with tube thoracostomy. An unstable patient with clinical signs consistent with a pneumothorax, however, should receive a tube thoracostomy prior to obtaining roentgenographic confirmation. If time permits, a nasogastric tube and Foley catheter should be placed, and the urine evaluated for blood (these procedures can be performed in the operating room). If kidney involvement is suspected because of hematuria or penetrating trauma in the area of a kidney or ureter in a patient requiring surgery, a single-shot IVP should be performed either in the ED or the operating room. An ECG is important in patients with possible cardiac involvement and in patients over the age of 40 going to the operating room. Tetanus status should be updated, and appropriate antibiotics covering bowel flora should be given. Operative management should rarely be delayed

Acute incarcerated hernia is a common surgical emergency. With advances in minimally invasive devices and techniques, the diagnosis and treatment have witnessed major changes, such as the use of laparoscopic surgery in some cases to achieve minimally invasive treatment. However, strict adherence to the indications and contraindications is still required. PMID:25489584

    A 79-year-old woman presented to a private medical practice 2 years previously for an elective ultrasound screening scan. This imaging provided the evidence for a diagnosis of an abdominal aortic aneurysm (AAA) to be made. Despite having a number of recognised risk factors for an AAA, her general practitioner at the time did not follow the guidance set out by the private medical professional, that is, to refer the patient to a vascular specialist to be entered into a surveillance programme and surgically evaluated. The patient became symptomatic with her AAA, was admitted to hospital and found to have a tender, symptomatic, 6 cm leaking AAA. She consented for an emergency open AAA repair within a few hours of being admitted to hospital, despite the 50% perioperative mortality risk. The patient spent 4 days in intensive care where she recovered well. She was discharged after a 12 day hospital stay but unfortunately passed away shortly after her discharge from a previously undiagnosed gastric cancer.

    The authors analyzed the single-center experience of treatment of 72 patients with abdominal aortic aneurisms and severe accompanied pathology. The aneurisms were repaired by stent-grafts. All the patients had abdominal aortic aneurisms with the diameters from 41 to 84 mm against the background of severe somatic pathology. It was a contraindication to planned open surgery. An installation of stent-graft was successful in all 72 follow-ups. It wasn't necessary to use a conversion to open surgery. The follow-up period consisted of 44,6?2,1 months. Control ultrasound and computer tomography studies hadn't revealed an increase of aneurism sack sizes or "eakages". A reduction of abdominal aortic aneurism sizes was noted in 37 patients on 4-5% during first year after operation. The stent-graft implantation extends the possibilities of abdominal aortic aneurism treatment for patients from a high surgical risk group. PMID:26234059

    Gangliogliomas are uncommon tumors of the central nervous system and rarely occur in the lateral ventricle or present with drop metastasis. We report a 49-year-old male who presented with a six-week history of left leg pain and numbness. Clinical examination revealed no focal neurological deficits. Magnetic resonance imaging (MRI) demonstrated enhancing nodular lesions in the sacral spine abutting the S2 nerve root. Further imaging of the neuroaxis demonstrated a cystic lesion in the left frontal horn of the lateral ventricle. Gross total surgical resection of the ventricular lesion was performed through a transcortical approach, followed by resection of the sacral spinal drop metastasis in a staged manner. A histopathological analysis revealed the diagnosis of low-grade ganglioglioma. To our knowledge, this is the first reported case of a low-grade intraventricular ganglioglioma presenting with symptoms associated with drop metastasis in an adult patient.

    Postoperative wound infections in spinal surgery remain an important complication to diagnose and treat successfully. In most cases of deep infection, even with instrumentation, aggressive soft-tissue debridement followed by intravenous antibiotics is sufficient. This report presents a patient who underwent L3-S1 laminectomy and pedicle screw placement including bicortical sacral screws. This patient went on to develop multiple (7) recurrent infections at the operative site over a 5-year period. Continued investigation eventually revealed a large presacral abscess, which remained the source of recurrent bacterial seeding via the remaining bone tracts of the bicortical sacral screws placed during the original lumbar surgery. Two years after drainage of this presacral collection via a retroperitoneal approach, the patient remains symptom free. PMID:26613281

    Objective: This study retrospectively evaluated the efficacy and toxicity of particle therapy using carbon ions or protons for primary sacral chordomas. Methods: We evaluated 23 patients with primary sacral chordoma treated with carbon ion therapy (CIT) or proton therapy (PT) between July 2005 and June 2011 at the Hyogo Ion Beam Medical Center, Hyogo, Japan. The median patient age was 72 years. 14 patients were treated with 70.4 Gy equivalents (GyE) in 16 fractions and 9 were treated with 70.4 GyE in 32 fractions. CIT was used for 16 patients, and PT was used for 7 patients. Results: The median follow-up period was 38 months. At 3 years, local control (LC), overall survival (OS) and progression-free survival (PFS) for all patients were 94%, 83% and 68%, respectively. The log-rank test revealed that male sex was significantly related to better PFS ( p = 0.029). No other factors, including dose fractionation and ion type, were significant for LC, OS or PFS. In nine patients, ≥Grade 3 acute dermatitis was observed, and ≥Grade 3 late toxicities were observed in nine patients. The 32-fraction protocol reduced severe toxicities in both the acute and late phases compared with the 16-fraction protocol. Conclusion: Particle therapy for patients with sacral chordoma showed favourable LC and OS. Severe toxicities were successfully reduced by modifying the dose fractionation and treatment planning in the later treatment era. Thus, this therapeutic modality should be considered useful and safe. Advances in knowledge: This is the first study including both CIT and PT for sacral chordomas. PMID:24288399

    Sacral neuromodulation (SNM) therapy has revolutionized the management of many forms of anal incontinence, with an expanded use and a medium-term efficacy of 75% overall. This review discusses the technique of SNM therapy, along with its complications and troubleshooting and a discussion of the early data pertaining to peripheral posterior tibial nerve stimulation in incontinent patients. Future work needs to define the predictive factors for neurostimulatory success, along with the likely mechanisms of action of their therapeutic action. PMID:24759349

    Purpose: To summarize the results of treatment for sacral chordoma in Phase I-II and Phase II carbon ion radiotherapy trials for bone and soft-tissue sarcomas. Patients and Methods: We performed a retrospective analysis of 38 patients with medically unresectable sacral chordomas treated with the Heavy Ion Medical Accelerator in Chiba, Japan between 1996 and 2003. Of the 38 patients, 30 had not received previous treatment and 8 had locally recurrent tumor after previous resection. The applied carbon ion dose was 52.8-73.6 Gray equivalents (median, 70.4) in a total of 16 fixed fractions within 4 weeks. Results: The median patient age was 66 years. The cranial tumor extension was S2 or greater in 31 patients. The median clinical target volume was 523 cm{sup 3}. The median follow-up period was 80 months. The 5-year overall survival rate was 86%, and the 5-year local control rate was 89%. After treatment, 27 of 30 patients with primary tumor remained ambulatory with or without supportive devices. Two patients experienced severe skin or soft-tissue complications requiring skin grafts. Conclusion: Carbon ion radiotherapy appears effective and safe in the treatment of patients with sacral chordoma and offers a promising alternative to surgery.

    Objective: Non-operative management of abdominal injuries has recently become more common. Especially non-operative treatment of blunt abdominal trauma is gaining wide acceptance. In this study, the efficacy of non-operative treatment in abdominal trauma (blunt penetrating) is discussed. Material and Methods: All patients who received treatment due to abdominal trauma from November 2008 to January 2013 were retrospectively analyzed. The demographic characteristics, type of injury, injured organ, type of treatment (operative vs. nonoperative) and mortality data were evaluated. Results: The study includes 115 patients treated for abdominal trauma in our department. The mechanism of trauma was stab wounds in 60%, blunt abdominal trauma in 23.5% and gunshot wounds in 16.5%. Forty-two patients (36.5%) were operated for hemodynamic instability and/or peritonitis on admission. The remaining 63.5% of patients (n=73) were treated nonoperatively, 10 of whom required laparotomy during follow-up. The remaining 63 patients were treated with non-operative management. The success rate for non-operative treatment was 86.3% and there was no difference in terms of the types of injuries. The mortality rate was 4.3% (n= 5) in the whole series, but there were no deaths among the patients who had received non-operative treatment. In the whole patient group 54.2% (n=63) were treated nonoperatively. Conclusion: Nonoperative treatment in abdominal trauma is safe and effective. Patients with clinical stability and normal physical examination findings can be treated nonoperatively with close monitoring. PMID:25931868

    A sacral pressure ulcer developed in a patient hospitalized for cerebral infarction. Each time necrotic tissue was debrided from the ulcer, pressure hemostasis was necessary to stop the bleeding. As treatment continued, the pressure required to stop the bleeding caused the ulcer to worsen, leading to a downward spiral in the patient's condition. While trying to determine the cause of this problem, we discovered that the patient had von Willebrand disease. Medication controlled the bleeding, and the pressure ulcer began to heal at the same time. It was clear to us that conservative treatment would lead to a complete cure but that the healing process would take a long time and require continued administration of an expensive drug. We decided, therefore, to close the wound with a fasciocutaneous flap so that the patient could be quickly transferred to a rehabilitation hospital. About 1 month after surgery, epithelialization was complete, we were able to discontinue medication, and the patient was discharged. This experience demonstrates the importance of determining the cause of any deviation from the normal course of healing in pressure ulcers. It also indicates that the use of fasciocutaneous flaps, which involve little intraoperative bleeding in short surgeries, is appropriate in cases like this one.

    The first 50 patients who have received sacral anterior root stimulator implants are presented, with follow-up of from 1 to 9 years. Forty-nine are alive and 43 are regularly using their implants for micturition. Of the 49 living, 39 are "very pleased, without significant reservations", six are pleased on balance but have reservations, and four are dissatisfied. Residual urine volumes are substantially reduced in all patients who are using their implants. Ten of the 12 female patients and the majority of male patients have become continent. The voiding pressure in implant-driven micturition can be regulated by adjusting the stimulus parameters, and is always kept below 90 cm H2O. Of seven patients with ureteric reflux before operation, four have ceased to reflux and the other three are unchanged. Changes in the radiographic appearances of the bladder have been favourable or zero, but there have been two cases of deterioration in the upper urinary tracts. Significant harmful effects have been CSF leaks, urinary infections following post-operative urodynamic study, and accidental damage to roots. Anterior roots nearly always recover from accidental damage, and posterior roots do not. Images PMID:3491180

  6. Synchronization of sacral skin blood flow oscillations in response to local heating.

    Local heating causes an increase in skin blood flow by activating sensory axon reflex and metabolic nitric oxide controls. It has been observed that the remote skin area without temperature changes also shows a slightly increase in blood flow. The responsible mechanism of this indirect vasodilation remains unclear. We hypothesized that the remote skin area will have enhanced synchronization of blood flow oscillations (BFO), thus inducing a vasodilatory response. We studied BFO in two sites separated 10 cm of the sacral skin in 12 healthy people. Ensemble empirical mode decomposition method was used to decompose blood flow signals into a set of intrinsic mode functions (IMFs), and an IMF was selected to quantify each of myogenic, neurogenic, and metabolic modes of BFO. Then the instantaneous phase of the mode was calculated using the Hilbert transform. From the time series of phase difference between a pair of characteristic modes, we detected the epochs of phase synchronization and estimated the level of statistical significance using surrogate time series. The results showed that phase synchronization between neurogenic BFO was significantly higher in the period of the maximal vasodilation. We also observed a weak synchronization between myogenic BFO of the two skin sites. Our results suggested that synchronization of BFO may be associated with the changes in skin blood flow at the non-heated site.

  7. Sacral Nerve Stimulation For Urinary Urge Incontinence, Urgency-Frequency, Urinary Retention, and Fecal Incontinence

    PubMed Central

    2005-01-01

    Executive Summary Objective The aim of this review was to assess the effectiveness, safety, and cost of sacral nerve stimulation (SNS) to treat urinary urge incontinence, urgency-frequency, urinary retention, and fecal incontinence. Background: Condition and Target Population Urinary urge incontinence, urgency-frequency, urinary retention, and fecal incontinence are prevalent, yet rarely discussed, conditions. They are rarely discussed because patients may be uncomfortable disclosing their symptoms to a health professional or may be unaware that there are treatment options for these conditions. Briefly, urge incontinence is an involuntary loss of urine upon a sudden urge. Urgency-frequency is an uncontrollable urge to void, which results in frequent, small-volume voids. People with urgency-frequency may or may not also experience chronic pelvic pain. Urinary retention refers to the inability to void despite having the urge to void. It can be caused by a hypocontractile detrusor (weak or no bladder muscle contraction) or obstruction due to urethral overactivity. Fecal incontinence is a loss of voluntary bowel control. The prevalence of urge incontinence, urgency-frequency, and urinary retention in the general population is 3.3% to 8.2%, and the prevalence of fecal incontinence is 1.4% to 1.9%. About three-quarters of these people will be successfully treated by behaviour and/or drug therapy. For those who do not respond to these therapies, the options for treatment are management with diapers or pads, or surgery. The surgical procedures are generally quite invasive, permanent, and are associated with complications. Pads and/or diapers are used throughout the course of treatment as different therapies are tried. Patients who respond successfully to treatment may still require pads or diapers, but to a lesser extent. The Technology Being Reviewed: Sacral Nerve Stimulation Sacral nerve stimulation is a procedure where a small device attached to an electrode is

    A 52-year-old Hispanic woman presented to the emergency department, reporting worsening sharp lower right quadrant abdominal pain for 3 days. CT of the abdomen and pelvis showed evidence of inflammation in the peritoneal soft tissues adjacent to an enlarged and thick-walled appendix, an appendicolith, no abscess formation and a slightly thickened caecum consistent with acute appendicitis. During laparoscopic appendectomy, the caecum was noted to be firm, raising suspicion of malignancy. Surgical oncology team was consulted and open laparotomy with right hemicolectomy was performed. Pathology reported that the ileocaecal mass was not a malignancy but was, rather, actinomycosis. The patient was discharged after 10 days of intravenous antibiotics in the hospital, with the diagnosis of abdominal actinomycosis. Although the original clinical and radiological findings in this case were highly suggestive of acute appendicitis, abdominal actinomycosis should be in the differential for right lower quadrant pain as it may be treated non-operatively.

    The purpose of this study was to determine if a single dose of radiation to the rat abdomen leads to bacterial translocation into the mesenteric lymph nodes (MLN). A second issue addressed was whether translocation correlates with anatomic damage to the mucosa. The radiated group (1100 cGy) which received anesthesia also was compared with a control group and a third group which received anesthesia alone but no abdominal radiation. Abdominal radiation lead to 100% positive cultures of MLN between 12 hr and 4 days postradiation. Bacterial translocation was almost nonexistent in the control and anesthesia group. Signs of inflammation and ulceration of the intestinal mucosa were not seen until Day 3 postradiation. Mucosal damage was maximal by Day 4. Bacterial translocation onto the MLN after a single dose of abdominal radiation was not apparently dependent on anatomical, histologic damage of the mucosa.

    Recurrent abdominal pain is a common presenting complaint among children. A thorough history and physical examination and limited laboratory investigation should enable a physician to make a positive diagnosis of "functional" recurrent abdominal pain in 90% to 95% of cases; an organic cause is identified in only 5% to 10%. The care and thoroughness of the history and physical examination establish the physician's credibility; explaining the clinical basis for the diagnosis and educating the child and parents on what is known about the condition reassures the parents.

    Abdominal bloating is a very common and troublesome symptom of all ages, but it has not been fully understood to date. Bloating is usually associated with functional gastrointestinal disorders or organic diseases, but it may also appear alone. The pathophysiology of bloating remains ambiguous, although some evidences support the potential mechanisms, including gut hypersensitivity, impaired gas handling, altered gut microbiota, and abnormal abdominal-phrenic reflexes. Owing to the insufficient understanding of these mechanisms, the available therapeutic options are limited. However, medical treatment with some prokinetics, rifaximin, lubiprostone and linaclotide could be considered in the treatment of bloating. In addition, dietary intervention is important in relieving symptom in patients with bloating. PMID:24199004

    Forty-two abdominal and retroperitoneal abscesses were drained percutaneously under ultrasound guidance. A success rate of 85.7% was achieved. Subsequent surgery was required in only 5 patients. Postoperative and spontaneous abscesses did equally well. Most intra-abdominal and retroperitoneal abscesses are amenable to this form of percutaneous drainage. The procedure requires only local anaesthesia and is well tolerated. Surgical management should probably now be reserved for those cases which are considered unsuitable for percutaneous drainage or which fail to resolve following this procedure. PMID:6842496

    Lung fluke, Paragonimus westermani of Paragonimus species usually are accompanied by a persistent cough, hemoptysis, and chest pain. Extrapulmonary paragonimiasis caused by ectopic parasites in aberrant locations such as the abdominal wall, abdominal organs, and brain has been reported and the most commonly involved extrapulmonary organ is the brain. We present a case of 56-year-old male patient with intra-abdominal paragonimiasis who underwent laparoscopic excision of abdominal granuloma caused by parasite infection. An intra-abdominal mass associated with eosinophilia might be related to parasite infection. A laparoscopic approach is the most appropriate treatment modality in such benign abdominal pathology.

  15. Costal process of the first sacral vertebra: sexual dimorphism and obstetrical adaptation.

    The human sacrum is sexually dimorphic, with males being larger than females in most dimensions. Previous studies, though, suggest that females may have a longer costal process of the first sacral vertebra (S1) than males. However, these studies neither quantified nor tested statistically the costal process of S1. This study compares S1 with the five lumbar vertebrae (L1 to L5) for a number of metric dimensions, including costal process length. Four issues are addressed, the: 1) hypothesis that females have a longer costal process of S1 than males; 2)hypothesis that homologous structures (i.e., costal processes of L1 to S1) differ in their direction of sexual dimorphism; 3) importance of the costal process of S1 to the obstetrical capacity of the pelvis; and 4) evolution of sexual dimorphism in costal process length of S1. One hundred ninety-seven individuals, including males and females of American blacks and whites, from the Hamann-Todd and Terry Collections were studied. Results show that males are significantly larger than females for most vertebral measurements, except that females have a significantly longer costal process of S1 than males. Costal process length of S1 is positively correlated with the transverse diameter and circumference of the pelvic inlet. The magnitude of sexual dimorphism in costal process length of S1 ranks this measure among the most highly dimorphic of the pelvis. Compared with the humans in this study, australopithecines have a relatively long costal process of S1, but their broad sacrum was not associated with obstetrical imperatives. PMID:17266155

    OBJECTIVE Tarlov cysts (TCs) occur most commonly on extradural components of the sacral and coccygeal nerve roots. These lesions are often found incidentally, with an estimated prevalence of 4%-9%. Given the low estimated rates of symptomatic TC and the fact that symptoms can overlap with other common causes of low-back pain, optimal management of this entity is a matter of ongoing debate. Here, the authors investigate the effects of surgical intervention on symptomatic TCs and aim to solidify the surgical criteria for this disease process. METHODS The authors performed a retrospective review of data from consecutive patients who were surgically treated for symptomatic TCs from September 2011 to March 2013. Clinical evaluations and results from surveying pain and overall health were used. Univariate statistical analyses were performed. RESULTS Twenty-three adults (4 males, 19 females) who had been symptomatic for a mean of 47.4 months were treated with laminectomy, microsurgical exposure and/or imbrication, and paraspinous muscle flap closure. Eighteen patients (78.3%) had undergone prior interventions without sustained improvement. Thirteen patients (56.5%) underwent lumbar drainage for an average of 8.7 days following surgery. The mean follow-up was 14.4 months. Univariate analyses demonstrated that an advanced age (p = 0.045), the number of noted perineural cysts on preoperative imaging (p = 0.02), and the duration of preoperative symptoms (p = 0.03) were associated with a poor postoperative outcome. Although 47.8% of the patients were able to return to normal activities, 93.8% of those surveyed reported that they would undergo the operation again if given the choice. CONCLUSIONS This is one of the largest published studies on patients with TCs treated microsurgically. The data suggest that patients with symptomatic TCs may benefit from open microsurgical treatment. Although outcomes seem related to patient age, duration of symptoms, and extent of disease

    ABSTRACT Objectives: We report on the short-term outcomes of sacral neuromodulation (SNM) for treatment of idiopathic lower urinary tract dysfunction in Brazil (procedures performed before 2014). Materials and Methods: Clinical data and surgical outcomes of patients who underwent SNM staged procedures were retrospective evaluated. Urological assessment included a focused medical history and physical examination, measurement of postvoid residual volumes, urodynamics, and bladder diaries. A successful test phase has been defined by improvement of at least 50% of the symptoms, based on bladder diaries. Results: From January 2011 to December 2013, eighteen consecutive patients underwent test phase for SNM due to refractory overactive bladder (15 patients), non-obstructive chronic urinary retention (2 patients), and bladder pain syndrome/interstitial cystitis (1 patient). All patients underwent staged procedures at four outpatient surgical centers. Mean age was 48.3±21.2 (range 10-84 years). There were 16 women and 2 men. Median follow-up was 3 months. Fifteen patients (83.3%) had a successful test phase and underwent implantation of the pulse generator (IPG). Median duration of the test phase was 7 days (range 5–24 days). Mean age was 45.6±18.19 years in responders versus 61.66±34.44 years in non-responders (p=0.242). Mean operative time (test phase) was 99±33.12 min in responders versus 95±35 min for non-responders (p=0.852). No severe complications were reported. Conclusion: SNM is a minimally invasive treatment option for patients with refractory idiopathic lower urinary tract dysfunction. Our initial experience with staged technique showed that tined-lead electrodes yielded a high rate of responders and favorable clinical results in the short-term follow-up. PMID:27176186

    Epidural injections are commonly performed blindly in veterinary medicine. The aims of this study were to describe the lumbosacral ultrasonographic anatomy and to assess the feasibility of an ultrasound-guided epidural injection technique in dogs. A cross sectional anatomic atlas of the lumbosacral region and ex vivo ultrasound images were obtained in two cadavers to describe the ultrasound anatomy and to identify the landmarks. Sixteen normal weight canine cadavers were used to establish two variations of the technique for direct ultrasound-guided injection, using spinal needles or epidural catheters. The technique was finally performed in two normal weight cadavers, in two overweight cadavers and in five live dogs with radiographic abnormalities resulting of the lumbosacral spine. Contrast medium was injected and CT was used to assess the success of the injection. The anatomic landmarks to carry out the procedure were the seventh lumbar vertebra, the iliac wings, and the first sacral vertebra. The target for directing the needle was the trapezoid-shaped echogenic zone between the contiguous articular facets of the lumbosacral vertebral canal visualized in a parasagittal plane. The spinal needle or epidural catheter was inserted in a 45° craniodorsal-caudoventral direction through the subcutaneous tissue and the interarcuate ligament until reaching the epidural space. CT examination confirmed the presence of contrast medium in the epidural space in 25/25 dogs, although a variable contamination of the subarachnoid space was also noted. Findings indicated that this ultrasound-guided epidural injection technique is feasible for normal weight and overweight dogs, with and without radiographic abnormalities of the spine.

    Purpose: Sacral insufficiency (SI) fractures can occur as a late side effect of pelvic radiation therapy. Our goal was to determine the incidence, risk factors, and clinical course of SI fractures in patients treated with preoperative chemoradiation for rectal cancer. Materials and Methods: Between 1989 and 2004, 562 patients with non-metastatic rectal adenocarcinoma were treated with preoperative chemoradiation followed by mesorectal excision. The median radiotherapy dose was 45 Gy. The hospital records and radiology reports of these patients were reviewed to identify those with pelvic fractures. Radiology images of patients with pelvic fractures were then reviewed to identify those with SI fractures. Results: Among the 562 patients, 15 had SI fractures. The 3-year actuarial rate of SI fractures was 3.1%. The median time to SI fractures was 17 months (range, 2-34 months). The risk of SI fractures was significantly higher in women compared to men (5.8% vs. 1.6%, p = 0.014), and in whites compared with non-whites (4% vs. 0%, p = 0.037). On multivariate analysis, gender independently predicted for the risk of SI fractures (hazard ratio, 3.25; p = 0.031). Documentation about the presence or absence of pain was available for 13 patients; of these 7 (54%) had symptoms requiring pain medications. The median duration of pain was 22 months. No patient required hospitalization or invasive intervention for pain control. Conclusions: SI fractures were uncommon in patients treated with preoperative chemoradiation for rectal cancer. The risk of SI fractures was significantly higher in women. Most cases of SI fractures can be managed conservatively with pain medications.

    Abstract Background Sacral neuromodulation (SNM) has emerged as a treatment option for faecal incontinence (FI). However, its objective effect on symptoms and anorectal function is inconsistently described. This study aimed to systematically review the impact of SNM on clinical symptoms and gastrointestinal physiology in patients with FI, including factors that may predict treatment outcome. Methods An electronic search of MEDLINE (1946–2014)/EMBASE database was performed in accordance with PRISMA guidelines. Articles that reported the relevant outcome measures following SNM were included. Clinical outcomes evaluated included: frequency of FI episodes, FI severity score and success rates. Its impact on anorectal and gastrointestinal physiology was also evaluated. Results Of 554 citations identified, data were extracted from 81 eligible studies. Meta‐analysis of the data was precluded due to lack of a comparison group in most studies. After permanent SNM, ‘perfect’ continence was noted in 13–88% of patients. Most studies reported a reduction in weekly FI episodes (median difference of the mean −7.0 (range: −24.8 to −2.7)) and Wexner scores (median difference of the mean −9 (−14.9 to −6)). A trend towards improved resting and squeeze anal pressures and a reduction in rectal sensory volumes were noted. Studies failed to identify any consistent impact on other physiological parameters or clinicophysiological factors associated with success. Conclusion SNM improves clinical symptoms and reduces number of incontinence episodes and severity scores in patients with FI, in part by improving anorectal physiological function. However, intervention studies with standardized outcome measures and physiological techniques are required to robustly assess the physiological impact of SNM. PMID:26245170

    The modulatory effect of 5-hydroxytryptamine (5-HT) on the γ-aminobutyric acidA (GABAA) response was investigated in the neurones freshly dissociated from the rat sacral dorsal commissural nucleus (SDCN) using the nystatin perforated patch recording configuration under the voltage-clamp conditions.5-HT potentiated GABA-induced Cl− current (IGABA) without affecting the reversal potential of IGABA and the apparent affinity of GABA to its receptor.α-Methyl-5-HT mimicked the potentiation effect of 5-HT on IGABA while ketanserine blocked it. 1-Oleoyl-2-acetyl-glycerol (OAG) potentiated IGABA, and the effect of 5-HT on IGABA was occluded by OAG pretreatment. In the presence of chelerythrine, 5-HT failed to potentiate IGABA, suggesting that protein kinase C (PKC) is involved in the pathway through which the activation of the 5-HT2 receptor potentiates the IGABA.The facilitatory effect of 5-HT on IGABA remained in the presence of BAPTA-AM. LiCl also had no effect on 5-HT-induced potentiation of IGABA.H-89, genistein, okadaic acid and pervanadate all had no effects on 5-HT potentiation of IGABA. Pertussis toxin treatment for 6–8 h did not block the facilitatory effect of 5-HT on IGABA.The present results show that GABAA receptor in the rat SDCN could be modulated in situ by 5-HT, one of the major transmitters involved in the supraspinal control of nociception, and that the phosphorylation of GABAA receptor by PKC may be sufficient to support such modulation. The results also strongly support the hypothesis that the cotransmission by 5-HT and GABA has an important role in the spinal cord. PMID:9690871

    In 2008, patients in the intensive care unit (ICU) at Danbury Hospital, Danbury, Connecticut, experienced 79 pressure ulcers. As a result, pressure ulcer-prevention interventions were standardized in critical care and medical-surgical units and education was provided to all direct patient care staff about principles of skin care and prevention. Following these efforts, 53 ICU patients developed pressure ulcers in the sacral area in fiscal year 2009, representing a 12.5% incidence for the ICU as compared to a 3.4% overall pressure ulcer incidence for the total hospital. In order to achieve additional reduction in pressure ulcer incidence, we replicated an initiative that called for application of a silicone foam dressing every 3 days to determine its effect on sacral pressure ulcer incidence in the ICU. We found that the use of the dressing further diminished the incidence of sacral pressure ulcers in our patients.

    Vacuum-assisted closure (VAC) therapy is a new entrant in wound care after growth factors and alginate or hydrocolloid dressing, in the treatment of pressure ulcers. We have been using this technique for diabetic foot ulcers. A young nondiabetic man presented with a large sacral bed sore after high doses of ionotropes in an intensive care unit for treating severe hypotension. His wound was debrided, and instead of flap surgery in such infected wound, he was treated with VAC therapy. The complete wound healing was achieved in 6 weeks and at half the cost of flap surgery. Moreover, the chances of flap failure and its related complications were eliminated.

    A 61-year-old man presented via the emergency department with a few days history of abdominal and colic occlusion symptoms. He presented signs of sepsis, midline lumbar spine tenderness and reduced hip flexion. Computer tomography of the abdomen and pelvis showed a presacral collection contiguous with the posterior part of the colo-rectal anastomosis, and MRI lumbar spine revealed abscess invation into the epidural space. He underwent a laparotomy with washout of the presacral abscess and a colostomy with a prolonged course of intravenous antibiotic therapy. At 3 weeks after initial presentation he had made a full clinical recovery with progressive radiological resolution of the epidural abscess. The objective of the case report is to highlight a unique and clinically significant complication of a rare post-operative complication after rectal surgery and to briefly discuss other intra-abdominal sources of epidural abscess.

    The purpose of this study is to describe the outcomes of partial colpocleisis for mesh erosions after sacrocolpopexy. We retrospectively report our surgical management of mesh erosion after sacrocolpopexy. Between 1998 and 2006, we performed 499 sacral colpopexies and treated 21 patients for mesh erosion, including three referrals. Mean (range) time to diagnosis was 10.3 months (1-49). Grafts materials included: Mersilene (13), Prolene (7), and Pelvicol (1). Surgical outcomes were available for 19 patients. Ten (48%) patients were cured by the initial partial colpocleisis, while nine (45%) required a second or third (2, 10%) vaginal operation. All of the second and third vaginal excisions failed. Eight patients had an abdominal excision, and two patients required a second abdominal procedure. The success rate for the first and second abdominal resections was 38% (3/8) and 100% (2/2). Abdominal surgeries had higher blood loss (84 vs 378 cc, p = 0.012) longer hospitalization (outpatient vs 4.2 days p = 0.001), and additional morbidity (18.6%). Potential contributing factors to surgical failure were the presence of Actinomyces and current smoking. We recommend initial transvaginal mesh resection with partial colpocleisis for synthetic mesh erosions after sacrocolpopexy. Vaginal failures may be better served by an abdominal excision. Potential contributors to failure include current smoking and the presence of Actinomyces.

    We present the case of a 43-year-old gentleman who presented to the emergency room with acute abdominal distension, confusion and vascular collapse. The emergent radiologic imaging obtained showed massive bilateral adrenal enlargement, but despite the initial clinical suspicion of possible overwhelming sepsis and/or massive abdominal/intralesional hemorrhage, lab tests based obtained rapidly confirmed the diagnosis of acute Addisonian crisis which responded dramatically to adrenocorticoid hormone replacement therapy and aggressive fluid resuscitation. The patient's established history of metastatic lung cancer confirmed this as a case of metastatic massive bilateral adrenal metastases with an initial presentation of acute adrenal insufficiency which is uncommon in the setting of metastatic carcinomatosis but more typically associated with lymphomas. Recognition of this clinical possibility is vital to enable rapid diagnosis and consequent life saving therapy. PMID:27328473

    First cause of secondary hypertension is renovascular hypertension which presents abdominal bruit in 16 to 20% of cases. This clinical sign is also associated with other vascular disease of the abdomen such as celiac trunk stenosis and/or aneurysms located on the pancreaticoduodenal or gastroduodenal arcs level, with little representation among aneurysm. They usually appear on a context of digestive complications like neoplasias, chronic pancreatitis or gastric obstructions possibly with obstructive icterus, hemorrhage and acute abdomen episodes. Its presentation in other contexts is rare and constitutes a diagnostic challenge. Diagnosis is made by abdominal arteriography which is the best method because you can locate the problem as well as intervene therapeutically with embolization of the aneurysme. We would like to emphasize the importance of a quick diagnosis due to the risk of rupture and the high morbi-mortality associated.

    Congenital abdominal wall defects that are located outside of the anterior wall are extremely rare and difficult to classify because there are no well accepted guidelines. There are two regions outside of the anterior wall: the flank or lateral wall; and the lumbar region. We report the case of a patient with an oval 3 cm-diameter hernia defect located above the anterior axillary line, which affects all layers of the muscular wall. An anorectal malformation consisting of a recto-vestibular fistula was also identified, and chest X-ray showed dextrocardia. The suggested treatment is repair of the defect before 1 year of age. Given that the anomalies described may accompany lateral abdominal wall hernia, it is important to diagnose and treat the associated defects.

    We report the case of a 39 year-old woman with many years of intermittent abdominal pain who was found to have cystic masses evocative of cystic lymphangioma involving the posterior mediastinal and retroperitoneum. Worsening abdominal pain led to a recommendation for laparoscopic unroofing and decompression of the cysts. During the postoperative period, hemorrhagic shock required reintervention with excision of the tumoral mass. Pathologic examination revealed lymphangioleiomyomatosis (LAM). On the 15th postoperative day, the patient developed a chylopneumothorax which required prolonged chest tube drainage. The presence of multiple polycystic lesions in the pulmonary parenchyma supported the diagnosis of diffuse LAM with primary extrapulmonary presentation. This diagnosis should be considered preoperatively since it modifies the treatment: a complete excision of the cystic lesions seems to be necessary in order to prevent bleeding and lymphatic extravasation.

    Incisional hernia is one of the classic complications after abdominal surgery. The chronic, gradual increase in size of some of these hernias is such that the hernia ring widens to a point where there is a loss of substance in the abdominal wall, herniated organs can become incarcerated or strangulated while poor abdominal motility can alter respiratory function. The surgical treatment of small (<5 cm) incisional hernias is safe and straightforward, by either laparotomy or laparoscopy. For large hernias, surgical repair is often difficult. After reintegration of herniated viscera into the abdominal cavity, the abdominal wall defect must be closed anatomically in order to restore the function to the abdominal wall. Prosthetic reinforcement of the abdominal wall is mandatory for long-term successful repair. There are multiple techniques for prosthetic hernia repair, but placement of Dacron mesh in the retromuscular plane is our preference. PMID:23137643

    The sacrum, by virtue of its anatomic location plays a key role in providing stability and strength to the pelvis. Presence of intervertebral discs in sacrum and coccyx is rare. Knowledge of its variations is of utmost importance to surgeons and radiologists. The current study focused on the presence of intervertebral discs between the sacral and coccygeal vertebrae in south Indian cadaveric pelvises. We observed 56 adult pelvises of which, 34 (61%) pelvises showed the presence of intervertebral discs between the sacral vertebrae and between the coccygeal vertebrae, while 22 (39%) pelvises did not have the intervertebral discs either in the sacrum or the coccyx. We also found that most of the specimens had discs between S1 and S2 vertebrae (39%), followed by, between S4 and S5 (18%), between S2–S3 (14%) and least being between S3–S4 (13%). In the coccyx it was found that 7% of pelvises had disc between Co1-Co2, 4% of them had between Co2-Co3 and 4% had between Co3-Co4. Knowledge regarding such anatomic variations in the sacro-coccygeal region is important to note because they require alterations in various instrumentation procedures involving the sacrum.

    Abstract Background: The aim of this study was to compare the biomechanical characteristics between bilateral and unilateral lumbo-iliac fixation in unilateral comminuted sacral fractures (USF) by finite element analysis. Methods: A 3-dimensional finite element model of unilateral sacral fractures was simulated. Three kinds of implants were instrumented into the model, including the unilateral lumbopelvic fixation (ULF), bilateral lumbopelvic fixation (BLF), and unilateral iliac fixation with bilateral lumbar pedicle screws (UBF). Loads of compression and rotation were distributed to the superior endplate of L3. To evaluate the biomechanical properties, the construct stiffness, the micromotion of the fractures, the stress distribution of implants, and the balance of hemilumbar vertebra are recorded and analyzed. Results: The highest construct stiffness was provided by BLF. In BLF model, the displacement between iliums was only 0.009 mm (compressional) and 0.001 mm (rotational), which was less than that under normal condition (0.02 mm). The maximum von Misses stress of implants appeared on the UBF. By using unilateral fixation, the L4 endured obvious imbalance on bilateral hemivertebra. A marked difference was exposed in BLF and UBF models, and the equilibrium of stress and activity was shown. Conclusion: From the finite element view, the stability of ULF is insufficient to reconstruct the posterior pelvic ring. Furthermore, the unilateral fixation may lead to imbalance of lumbar vertebra and pelvis. On the contrary, the BLF can provide satisfied stability and lumbar balance. PMID:27749563

    The purpose of this study is to examine the morphological and kinematical changes of the uterus induced by electrical stimulation applied to the skin just above the second and fourth posterior sacral foramens (sacral surface electrical stimulation [ssES]) in 26 healthy subjects. Out of them, eight subjects who had severe pain subjectively during every menstruation received ssES just in menstruation. Morphological and functional changes of the uterus were examined by using T2-weighted magnetic resonance (MR) imaging and T1-weighted MR cinematography, respectively. Cyclic electrical stimulation for 15 min with 5 sec ON and 5 sec OFF was applied just before MR scanning. A decrease in thickness of the muscular layer of the uterus was observed in every subject after ssES for 15 min and was significant as compared with the thickness before ssES. Periodic uterine movement during menstruation was observed in the subjects with severe menstrual pain in MR cine and the power spectrum analysis of the movement showed a marked decrease in peak power and frequency after ssES treatment. We conclude that ssES causes a reduction of static muscle tension of the uterus in all menstrual cycle periods and suppression of uterine peristalsis during menstruation in the subjects with severe menstrual pain. Possible neural mechanisms for these static and dynamic effects of ssES on the uterus at spinal level are discussed. PMID:16340175

  19. Acute Abdominal Pain in Children.

    Acute abdominal pain accounts for approximately 9% of childhood primary care office visits. Symptoms and signs that increase the likelihood of a surgical cause for pain include fever, bilious vomiting, bloody diarrhea, absent bowel sounds, voluntary guarding, rigidity, and rebound tenderness. The age of the child can help focus the differential diagnosis. In infants and toddlers, clinicians should consider congenital anomalies and other causes, including malrotation, hernias, Meckel diverticulum, or intussusception. In school-aged children, constipation and infectious causes of pain, such as gastroenteritis, colitis, respiratory infections, and urinary tract infections, are more common. In female adolescents, clinicians should consider pelvic inflammatory disease, pregnancy, ruptured ovarian cysts, or ovarian torsion. Initial laboratory tests include complete blood count, erythrocyte sedimentation rate or C-reactive protein, urinalysis, and a pregnancy test. Abdominal radiography can be used to diagnose constipation or obstruction. Ultrasonography is the initial choice in children for the diagnosis of cholecystitis, pancreatitis, ovarian cyst, ovarian or testicular torsion, pelvic inflammatory disease, pregnancy-related pathology, and appendicitis. Appendicitis is the most common cause of acute abdominal pain requiring surgery, with a peak incidence during adolescence. When the appendix is not clearly visible on ultrasonography, computed tomography or magnetic resonance imaging can be used to confirm the diagnosis. PMID:27175718

    AIM: To investigate the nature and severity of AE related to sacral neurostimulation (SNS). METHODS: Based on Pubmed and Embase searches, we identified published trials and case series of SNS for fecal incontinence (FI) and extracted data on adverse events, requiring an active intervention. Those problems were operationally defined as infection, device removal explant or need for lead and/or generator replacement. In addition, we analyzed the Manufacturer and User Device Experience registry of the Federal Drug Administration for the months of August - October of 2015. Events were included if the report specifically mentioned gastrointestinal (GI), bowel and FI as indication and if the narrative did not focus on bladder symptoms. The classification, reporter, the date of the recorded complaint, time between initial implant and report, the type of AE, steps taken and outcome were extracted from the report. In cases of device removal or replacement, we looked for confirmatory comments by healthcare providers or the manufacturer. RESULTS: Published studies reported adverse events and reoperation rates for 1954 patients, followed for 27 (1-117) mo. Reoperation rates were 18.6% (14.2-23.9) with device explants accounting for 10.0% (7.8-12.7) of secondary surgeries; rates of device replacement or explant or pocket site and electrode revisions increased with longer follow up. During the period examined, the FDA received 1684 reports of AE related to SNS with FI or GI listed as indication. A total of 652 reports met the inclusion criteria, with 52.7% specifically listing FI. Lack or loss of benefit (48.9%), pain or dysesthesia (27.8%) and complication at the generator implantation site (8.7%) were most commonly listed. Complaints led to secondary surgeries in 29.7% of the AE. Reoperations were performed to explant (38.2%) or replace (46.5%) the device or a lead, or revise the generator pocket (14.6%). Conservative management changes mostly involved changes in stimulation

    This study evaluated the relationship between the morphology of the sacrum-the sole bony link between the tail or coccyx and the rest of the body-and tail length (including presence/absence) and function using a comparative sample of extant mammals spanning six orders (Primates, Carnivora, Rodentia, Diprotodontia, Pilosa, Scandentia; N = 472). Phylogenetically-informed regression methods were used to assess how tail length varied with respect to 11 external and internal (i.e., trabecular) bony sacral variables with known or suspected biomechanical significance across all mammals, only primates, and only non-primates. Sacral variables were also evaluated for primates assigned to tail categories ('tailless,' 'nonprehensile short-tailed,' 'nonprehensile long-tailed,' and 'prehensile-tailed'). Compared to primates with reduced tail lengths, primates with longer tails generally exhibited sacra having larger caudal neural openings than cranial neural openings, and last sacral vertebrae with more mediolaterally-expanded caudal articular surfaces than cranial articular surfaces, more laterally-expanded transverse processes, more dorsally-projecting spinous processes, and larger caudal articular surface areas. Observations were corroborated by the comparative sample, which showed that shorter-tailed (e.g., Lynx rufus [bobcat]) and longer-tailed (e.g., Acinonyx jubatus [cheetah]) non-primate mammals morphologically converge with shorter-tailed (e.g., Macaca nemestrina) and longer-tailed (e.g., Macaca fascicularis) primates, respectively. 'Prehensile-tailed' primates exhibited last sacral vertebrae with more laterally-expanded transverse processes and greater caudal articular surface areas than 'nonprehensile long-tailed' primates. Internal sacral variables performed poorly compared to external sacral variables in analyses of extant primates, and were thus deemed less useful for making inferences concerning tail length and function in extinct primates.

    Background Anterior sacral root stimulation combined with sacral posterior rhizotomy restores bladder function in spinal cord-injured patients suffering from hyperactive bladder. After successful implantation of bladder stimulator, urinary infection rate decreases, and patients are able to get rid of indwelling urinary catheters, which in turn reduce the risks for vesical malignancy. We present a spinal cord injury patient with non-functioning Brindley sacral anterior root stimulator, who developed carcinoma of urinary bladder. Case presentation A Caucasian male, who was born in 1943, sustained paraplegia at T-4 (ASIA-B) in 1981. This patient underwent implantation of sacral anterior root stimulator in September 1985. The bladder stimulator started giving trouble since 1996 and the patient went back to using indwelling urethral catheter. In August 2006, this patient passed blood in urine after a routine change of indwelling catheter. Cystoscopy showed unhealthy bladder mucosa. Bladder biopsy revealed carcinoma, which was infiltrating bundles of muscularis propria. Many of the nests showed evidence of squamous differentiation, while others could be transitional or squamous. This patient underwent cystectomy with lymphadenectomy in March 2007 in a hospital nearer his home. Histology showed three nodes involved. This patient has been doing well since the operation. Conclusion Occurrence of vesical malignancy in this patient with non-functioning bladder stimulator is a timely reminder to all health professionals, and health care managers that concerted efforts should be made to rectify a non-functioning sacral anterior root stimulator as soon as possible. Otherwise, facilities should be made available in the community for the spinal cord injury patient to use intermittent catheterisation and thereby, avoid permanent indwelling catheter, vesical calculi and urine infections, which are risk factors for bladder cancer.

    Nerve growth factor has been proposed to mediate many structural and chemical changes in bladder sensory neurons after injury or inflammation. We have examined the expression of receptors for the glial cell line-derived neurotrophic factor (GDNF) family within sensory terminals located in the sacral spinal cord and in bladder-projecting sacral dorsal root ganglion neurons of adult female Sprague-Dawley rats. Nerve fibers immunolabelled for GFRalpha1 (GDNF receptor), GFRalpha2 (neurturin receptor), or GFRalpha3 (artemin receptor) showed distinct distribution patterns in the spinal cord, suggesting separate populations of sensory fibers with different functions: GFRalpha1-labeled fibers were in outer lamina II and the lateral-collateral pathway and associated with autonomic interneurons and preganglionic neurons; GFRalpha2-labeled fibers were only in inner lamina II; GFRalpha3-labeled fibers were in lamina I, the lateral-collateral pathway, and areas surrounding dorsal groups of preganglionic neurons and associated interneurons. Immunofluorescence studies of retrogradely labelled bladder-projecting neurons in sacral dorsal root ganglia showed that approximately 25% expressed GFRalpha1 or GFRalpha3 immunoreactivity, the preferred receptors for GDNF and artemin, respectively. After cyclophosphamide-induced bladder inflammation, fluorescence intensity of GFRalpha1-positive fibers increased within the dorsal horn, but there was no change in the GFRalpha2- or GFRalpha3-positive fibers. These studies have shown that GDNF and artemin may target bladder sensory neurons and potentially mediate plasticity of sacral visceral afferent neurons following inflammation. Our results have also revealed three distinct subpopulations of sensory fibers within the sacral spinal cord, which have not been identified previously using other markers.

    Purpose: To investigate the relative importance of patient-reported hip and sacral pain after pelvic radiotherapy (RT) for gynecological cancer and its relationship to the absorbed doses in these organs. Methods and Materials: We used data from a population-based study that included 650 long-term gynecological cancer survivors treated with pelvic RT in the Gothenburg and Stockholm areas in Sweden with a median follow-up of 6 years (range, 2-15) and 344 population controls. Symptoms were assessed through a study-specific postal questionnaire. We also analyzed the hip and sacral dose-volume histogram data for 358 of the survivors. Results: Of the survivors, one in three reported having or having had hip pain after completing RT. Daily pain when walking was four times as common among the survivors compared to controls. Symptoms increased in frequency with a mean absorbed dose >37.5 Gy. Also, two in five survivors reported pain in the sacrum. Sacral pain also affected their walking ability and tended to increase with a mean absorbed dose >42.5 Gy. Conclusions: Long-term survivors of gynecological cancer treated with pelvic RT experience hip and sacral pain when walking. The mean absorbed dose was significantly related to hip pain and was borderline significantly related to sacral pain. Keeping the total mean absorbed hip dose below 37.5 Gy during treatment might lower the occurrence of long-lasting pain. In relation to the controls, the survivors had a lower occurrence of pain and pain-related symptoms from the hips and sacrum compared with what has previously been reported for the pubic bone.

    The operative mortality following conventional abdominal aortic aneurysm (AAA) repair has not fallen significantly over the past two decades. Since its inception in 1991, endovascular aneurysm repair (EVAR) has provided an alternative to open AAA repair and perhaps an opportunity to improve operative mortality. Two recent large randomised trials have demonstrated the short and medium term benefit of EVAR over open AAA repair, although data on the long term efficacy of the technique are still lacking. This review aimed at providing an overview of EVAR and a discussion of the potential benefits and current limitations of the technique. PMID:17267674

    Number of cases of filariasis have been recently reported in the Hungarian medical literature, most of them caused by Dirofilaria repens . Dirofilaria repens is a mosquito-transmitted filarioid worm in the subcutaneous tissue of dogs and cats. Human infection manifests as either subcutaneous nodules or lung parenchymal disease, which may even be asymptomatic. The authors report a human Dirofilaria repens infection of the abdominal cavity in a 61-year-old man,who underwent laparotomy for acute abdomen. Intraoperatively, local peritonitis was detected caused by a white nemathhelminth, measured 8 cm in size. Histocytology confirmed that the infection was caused by Dirofilaria repens.

    We present the case of a 42-year old man who went to the emergency department because of spasmodic abdominal pain. The abdomen was soft. A gastroscopy and a colonoscopy were without pathological findings. The laboratory analyses indicated anemia. The differential blood count showed basophilic granules in the red blood cells. The blood lead level was elevated. A lead poisoning was diagnosed. The cause was the oral intake of an ayurvedic medication which the patient had received in Bangladesh to treat his vitiligo.

    Intraperitoneal or retroperitoneal cystic structures in the newborn appear with a variable clinical picture and in the case of intra-abdominal cysts, surgery is performed mostly on an emergency basis. In such cases the exact preoperative diagnosis is difficult and is seldom made. With early laparotomy, extensive small bowel resection can usually be avoided. Retroperitoneal lesions are mostly of renal origin; in such cases, preoperative diagnosis is easy, being based on specific examinations. In the year 1973, 5 newborns with an intraperitoneal or retroperitoneal cyst have been treated surgically. In this series, one infant died after resection of 90% of the small bowel.

    Almost every abdominal organ is now amenable to laparoscopic surgery. Laparoscopic appendicectomy is a routine procedure which also permits identification of other conditions initially confused with an inflamed appendix. However, assessment of appendiceal inflammation is more difficult. Almost all colonic procedures can be performed laparoscopically, at least partly, though resection for colonic cancer is still controversial. For simple patch repair of perforated duodenal ulcers laparoscopy is ideal, and inguinal groin hernia can be repaired satisfactorily with a patch of synthetic mesh. Many upper abdominal procedures, however, still take more time than the open operations. These techniques reduce postoperative pain and the incidence of wound infections and allow a much earlier return to normal activity compared with open surgery. They have also brought new disciplines: surgeons must learn different hand-eye coordination, meticulous haemostasis is needed to maintain picture quality, and delivery of specimens may be problematic. The widespread introduction of laparoscopic techniques has emphasised the need for adequate training (operations that were straight-forward open procedures may require considerable laparoscopic expertise) and has raised questions about trainee surgeons acquiring adequate experience of open procedures.

    One of the key challenges in perioperative care is to reduce postoperative morbidity and mortality. Patients who develop postoperative morbidity but survive to leave hospital have often reduced functional independence and long-term survival. Mechanical ventilation provides a specific example that may help us to shift thinking from treatment to prevention of postoperative complications. Mechanical ventilation in patients undergoing surgery has long been considered only as a modality to ensure gas exchange while allowing maintenance of anesthesia with delivery of inhaled anesthetics. Evidence is accumulating, however, suggesting an association between intraoperative mechanical ventilation strategy and postoperative pulmonary function and clinical outcome in patients undergoing abdominal surgery. Non-protective ventilator settings, especially high tidal volume (VT) (>10-12mL/kg) and the use of very low level of positive end-expiratory pressure (PEEP) (PEEP<5cmH2O) or no PEEP, may cause alveolar overdistension and repetitive tidal recruitment leading to ventilator-associated lung injury in patients with healthy lungs. Stimulated by previous findings in patients with acute respiratory distress syndrome, the use of lower tidal volume ventilation is becoming increasingly more common in the operating room. However, lowering tidal volume, though important, is only part of the overall multifaceted approach of lung protective mechanical ventilation. In this review, we aimed at providing the most recent and relevant clinical evidence regarding the use of mechanical ventilation in patients undergoing abdominal surgery.

    For a considerable reduction of injuries caused by resection and spondylodesis of the lumbosacral region of the spine, the authors have developed a procedure of conservation of vascular extravertebra and neural nets by employing 10 cadavers. With this the transabdominal approach is used to form an aperture in SI and partially LV corpus vertebralis, by removing all pathological substances of the healthy spongious substance of the bone. The formed cavity is filled by two autografts, bone bits, antibiotics and hemostatic sponge. The two autografts are formed as a cross and their ends are clung to the edge of the entrance aperture of the bone. Stitches are placed to the periosteum and the strata of the abdominal wall.

    Chordoma is a rare and low-malignant neoplasm which is considered to arise from notochord remnants. Due to its large resistance to chemotherapy and radiotherapy, surgical resection so far is the prior treatment for chordoma. However, the recurrence rate is high even after complete surgical resection. Recently, targeted cancer therapy has been demonstrated to be effective in several other tumors, while the related research on chordoma is rare. Mitogen-activated protein kinase signaling pathway is acknowledged to participate in tumor development, in which Raf-1 and extracellular regulated protein kinase 1/2 (ERK1/2) play vital roles. In this study, we evaluated the expression of Raf-1 and ERK1/2 by immunohistochemical staining in 42 chordoma tissue and 16 distant normal tissue. Moreover, we also investigated the correlations of Raf-1 and ERK1/2 expression with clinical features in sacral chordoma. Expression of Raf-1 and ERK1/2 was both significantly higher in sacral chordoma tissue than distant normal tissue (P = 0.008, P = 0.019). Raf-1 positive expression was related to surrounding muscle invasion (P = 0.032) and chordoma recurrence (P = 0.002), but the results did not indicate any association with patients’ age, gender, tumor size and location. ERK1/2 was associated with tumor size (P = 0.044) instead of other clinical factors (P > 0.05). Spearman correlation test showed close relation between ERK1/2 and Raf-1 (P = 0.001, r = 0.518). Kaplan–Meier survival Curve and log-rank test showed that Raf-1 positive expression was associated with shorter continuous disease-free survival time (CDFS) (P = 0.001), while ERK1/2 had no relation to CDFS (P = 0.961). Conclusively, Raf-1 may be an important biomarker in predicting the prognosis of chordoma patients. PMID:25755752

    The infectious complications of 122 consecutive abdominal twin deliveries over the period 1984-1989 were analyzed in a prospective clinical study, comparing them with 761 singleton abdominal deliveries over the period 1984-1986. The incidence of endometritis was nearly three-fold after twin deliveries and the incidence of abdominal wound infections nearly two-fold compared with singleton abdominal pregnancies (13.1/4.7% and 5.6/3.0%). The risk of amnionitis was increased ten-fold, 6 hours after rupture of the membranes in abdominal twin delivery, but no connection was found between amnionitis and endometritis, as in singleton abdominal deliveries. Multiple regression analysis indicated only two risk factors as regards puerperal endometritis after abdominal twin delivery: age under 25 years (odds ratio 6.9, 95% confidence limits 1.9-24.8), an association also seen in singleton abdominal deliveries, and a period of more than 6 hours from rupture of membranes to delivery (odds ratio 7.8, 95% confidence limits 2.1-28.5). Multiple pregnancy appears to be associated with an increased risk of endometritis. The etiological factors remain unknown, but a large placental bed and/or immunological factors may be implicated.

    The pudu (Pudu puda), which is the smallest deer in the world and inhabits central and southern Chile and Argentina, is a ruminant and a browsing herbivore. The aim of this study was to provide a reference for interpretation of the normal anatomy of the pudu's gastrointestinal tract as imaged by abdominal computed tomography (CT). For the study, one adult female pudu was used. After a 24-h fast, the pudu was anaesthetized and positioned in sternal recumbency at the CT table. Image acquisition began immediately after intravenous injection of contrast media (MD-76(®); 370 mgI/ml) into the cephalic vein. Injection of contrast material was administered as a biphasic protocol. First, a manual bolus of contrast material was injected at a rate of 4 ml/s. Then, an additional continuous infusion injection (0.1 ml/min) was performed for adequate opacification of vascular structures. Transverse images of 5 mm thickness and 5 mm interval were obtained with a fourth-generation CT scanner, from the ninth thoracic vertebra (T9) until the first sacral (S1) vertebrae. CT images were labelled and compared with anatomical reference images for ruminants. Structures that were identified in the abdominal cavity included the stomach with its four compartments (rumen, reticulum, omasum and abomasum), the small and large intestines, liver, spleen, kidneys and some major blood vessels (aorta, caudal vena cava). The distal loop of the ascending colon, the transverse colon, the pancreas and lymph nodes could not be identified. The resulting CT images provide a reference for normal cross-sectional abdominal anatomy of the adult pudu.

    Abdominal tuberculosis is an increasingly common disease that poses diagnostic challenge, as the nonspecific features of the disease which may lead to diagnostic delays and development of complications. This condition is regarded as a great mimicker of other abdominal pathology. A high index of suspicion is an important factor in early diagnosis. Abdominal involvement may occur in the gastrointestinal tract, peritoneum, lymphnodes or solid viscera. Various investigative methods have been used to aid in the diagnosis of abdominal tuberculosis. Early diagnosis and initiation of antituberculous therapy and surgical treatment are essential to prevent morbidity and mortality. Most of the patients respond very well to standard antitubercular therapy and surgery is required only in a minority of cases. Imaging plays an important role in diagnosis of abdominal tuberculosis because early recognition of this condition is important. We reviewed our experience with the findings on various imaging modalities for diagnosis of this potentially treatable disease. PMID:25356043

    Retroperitoneal fibrosis is a rare fibrosing reactive process that may be confused with mesenteric fibromatosis. Abdominal aorta aneurysm is rare too and mostly develops secondary to Behcet's disease, trauma, and infection or connective tissue diseases. Incidence of aneurysms occurring as a result of atherosclerotic changes increases in postmenopausal period. Diagnosis can be established with arteriography, tomography, or magnetic resonance imaging associated with clinical findings. Tumors and cysts should be considered in differential diagnosis. Abdominal ultrasound and contrast-enhanced computerized tomography revealed an infrarenal abdominal aorta aneurysm in a 41-year-old woman, but, on surgery, retroperitoneal fibrosis surrounding the aorta was detected. We present this interesting case because retroperitoneal fibrosis encircling the abdominal aorta can mimic abdominal aorta aneurysm radiologically.

    The present study aimed to determine the intra-abdominal pressure during front crawl swimming at different velocities in competitive swimmers and to clarify the relationships between stroke indices and changes in intra-abdominal pressure. The subjects were 7 highly trained competitive collegiate male swimmers. Intra-abdominal pressure was measured during front crawl swimming at 1.0, 1.2 and 1.4 m · s(-1) and during the Valsalva maneuver. Intra-abdominal pressure was taken as the difference between minimum and maximum values, and the mean of 6 stable front crawl stroke cycles was used. Stroke rate and stroke length were also measured as stroke indices. There were significant differences in stroke rate among all velocities (P < 0.05). However, there was no significant difference in stroke length by velocity. Significant within-subject correlations between intra-abdominal pressure and stroke rate or stroke length (P < 0.01) were observed, although there were no significant correlations between intra-abdominal pressure and stroke indices when controlling for swimming velocity. These findings do not appear to support the effectiveness of trunk training performed by competitive swimmers aimed at increasing intra-abdominal pressure. PMID:23868677

    The purpose of the present investigations was (1) to examine the spatial organization of preganglionic neurons of the sacral parasympathetic nucleus in the lumbosacral spinal cord of male adult rats and (2) to search, in this nucleus, for a possible segregation of sub-populations of neurons innervating the penis or the bladder, respectively. To estimate their spatial organization, neurons of the sacral parasympathetic nucleus were retrogradely labeled by wheat germ agglutinin coupled to horseradish peroxidase applied to the central end of the sectioned pelvic nerve. The sub-populations of lumbosacral neurons innervating the corpus cavernosum of the penis or the dome of the bladder were identified using transsynaptic retrograde labeling by pseudorabies virus injected into these organs in different rats. In both wheat germ agglutinin-labeled and pseudorabies virus-labeled rats, serial coronal sections were cut through the spinal L5-S1 segments. Labeled neurons were revealed by histochemistry (peroxidase experiments) or immunohistochemistry (pseudorabies virus experiments). By means of a three-dimensional reconstruction software developed in our laboratory, three-dimensional models were calculated from each spinal section image series. They revealed the spatial organization of (i) preganglionic neurons and (ii) neurons innervating the bladder or the penis. The different three-dimensional models were subsequently merged into a single one which revealed the segregation, within the sacral parasympathetic nucleus, of the sub-populations of neurons. Neurons labeled by virus injected into the penis extended predominantly from the rostral part of the L6 segment to the rostral part of the S1 segment while those labeled by bladder injections were distributed predominantly from the caudal part of the L6 segment to the caudal part of the S1 segment. These results support the hypothesis of a viscerotopic organization of sacral neurons providing the spinal control of pelvic organs.

  4. Pelvic X-ray misses out on detecting sacral fractures in the elderly - Importance of CT imaging in blunt pelvic trauma.

    Patients aged 75 years and older with blunt pelvic trauma are frequently seen in the ER. The standard diagnostic tool in these patients is the plain a.p.-radiograph of the pelvis. Especially lesions of the posterior pelvic ring are often missed due to e.g. bowel gas projection and enteric overlay. With a retrospective study covering these patients over a 3 year period in our level I trauma centre, we were able to evaluate the rate of missed injuries in the a.p.-radiograph whenever a corresponding CT scan was performed. Age, gender, and accompanying fractures of the pelvic ring were recorded. The intrinsic test characteristics and the performance in the population were calculated according to standard formulas. Thus, 233 consecutive patients with blunt pelvic trauma with both conventional radiographic examination and computed tomography (CT) were included. Thereof, 56 (23%) showed a sacral fracture in the CT scan. Of 233 pelvic X-ray-images taken, 227 showed no sacral fracture. 51 (21.7%) of these were false negative, yielding a sensitivity of just 10.5%. Average age of patients with sacral fractures was 85.1±6.1 years, with 88% being female. Sacral fractures were often accompanied by lesions of the anterior pelvic ring with pubic bone fractures in 75% of sacrum fracture cases. Second most concomitant fractures are found at the acetabulum (23.3%). Plain radiographic imaging is especially likely to miss out fractures of the posterior pelvic ring, which nowadays can be of therapeutic consequence. Besides the physicians experience in the ED, profound knowledge of insensitivity of plain radiographs in finding posterior pelvic ring lesions is crucial for a reliable diagnostic routine. Since the high mortality caused by prolonged immobilisation due to pelvic ring injuries, all fractures should be identified. We therefore provide a diagnostic algorithm for blunt pelvic trauma in the elderly. PMID:26861798

    The coccyx is a highly variable structure in the human caudal spine. Previous studies have revealed a significant correlation between coccyx shape and the pain syndrome coccygodynia. The aim of this study was to carry out a complex morphological evaluation of the coccyx in a group of asymptomatic patients of different sex and age examined by multislice computed tomography (MSCT) of the pelvis for different clinical reasons. MSCT pelvis examinations from various nontraumatic clinical conditions from consecutive adult patients (250 males and 250 females of comparable age, mean 54.9 ± 14.8 years) were used. Based on middle sagittal plane reconstructions: coccyx configuration (types I-IV according to Postacchini and Massobrio classification, each successive type characterized by a more pronounced anterior position of coccyx), number of segments, length and angles (intercoccygeal and lumbo-sacral) were measured. The results obtained were analyzed statistically. The following types of coccyx were observed in the study group: type I in 16.2 %, type II 40.0 %, type III 32.4 %, and type IV 11.4 % cases. In most cases (50.8 %), three segments were noted. Lumbo-sacral angle varied from 15.6° to 66.4° (average 41.6° ± 7.7°), and intercoccygeal angle from 0° to 107° (average 51° ± 23.3°). A significant negative correlation between age and number of segments as well as age and intercoccygeal angle was observed. In males, the coccyx was significantly longer, while in females the intercoccygeal angle was significantly wider. Type I was significantly more frequent in males, while type IV was found more often in females. The results obtained differ from other results in the literature. Our research could be useful to determine population standards, and help (together with clinical history) future studies of associations between idiopathic coccygodynia and coccyx morphology.

    Prolonged, unrelieved pressure is a major risk factor for pressure ulceration, and interface tissue pressures have been shown to be very high when a person is sitting. Using convenience sampling methods, 23 healthy participants (four men, 19 women, mean age 45 years, body mass index [BMI] range 20-45) participated in a prospective pilot study to evaluate the effect of BMI and two commonly used seating positions in standard hospital reclining chairs on tissue (especially sacral) interface pressures. Measurements were obtained when volunteers were seated upright with plantar surfaces of feet touching the floor (Position 1) and reclining with legs resting on an elevated surface (Position 2). Measurements were obtained for 6 minutes using a thin, flexible force sensing array 430-mm x 430-mm seat mat. Average pressure, maximum pressure, and the number of sensors reading >60 mm Hg and >80 mm Hg were used for analysis across the total surface and at the sacrum. Participants were categorized by BMI (category 1: 20-22, category 2: 23-28, category 3: 29+; no participants had a BMI <20). Leg elevation reduced average pressure across the total surface (from 42.9 mm Hg to 40.0 mm Hg, P = 0.015) and the number of sensors reading >60 mm Hg at the sacrum (from 31.4 to 27.1, P = 0.047). BMI and position were significantly correlated with the number of sensors reading >80 mm Hg (P = 0.008) and average pressure (P = 0.031). Pairwise comparisons showed significant differences existed between BMI categories 1 (average delta: -3.63, indicating down position is better) and 3 (average delta: 4.67, indicating up position is better) for the difference in number of sensors above 80 mm Hg (P = 0.030). Research is needed to further explore the relationship between BMI and tissue pressure, but the results of this study suggest that for patients with a BMI >29, elevating the heels/reclining the chair significantly reduces sacral tissue interface pressure.

Average pressure, maximum pressure, and the number of sensors reading >60 mm Hg and >80 mm Hg were used for analysis across the total surface and at the sacrum. Participants were categorized by BMI (category 1: 20-22, category 2: 23-28, category 3: 29+; no participants had a BMI <20). Leg elevation reduced average pressure across the total surface (from 42.9 mm Hg to 40.0 mm Hg, P = 0.015) and the number of sensors reading >60 mm Hg at the sacrum (from 31.4 to 27.1, P = 0.047). BMI and position were significantly correlated with the number of sensors reading >80 mm Hg (P = 0.008) and average pressure (P = 0.031). Pairwise comparisons showed significant differences existed between BMI categories 1 (average delta: -3.63, indicating down position is better) and 3 (average delta: 4.67, indicating up position is better) for the difference in number of sensors above 80 mm Hg (P = 0.030). Research is needed to further explore the relationship between BMI and tissue pressure, but the results of this study suggest that for patients with a BMI >29, elevating the heels/reclining the chair significantly reduces sacral tissue interface pressure.

    The Abdominal gene is a member of the single homeotic complex of the beetle, Tribolium castaneum. An integrated developmental genetic and molecular analysis shows that Abdominal is homologous to the abdominal-A gene of the bithorax complex of Drosophila. abdominal-A mutant embryos display strong homeotic transformations of the anterior abdomen (parasegments 7-9) to PS6, whereas developmental commitments in the posterior abdomen depend primarily on Abdominal-B. In beetle embryos lacking Abdominal function, parasegments throughout the abdomen are transformed to PS6. This observation demonstrates the general functional significance of parasegmental expression among insects and shows that the control of determinative decisions in the posterior abdomen by homeotic selector genes has undergone considerable evolutionary modification.

    2014-01-01

    Abdominal hernias are common with over 20 million hernia repairs performed worldwide. Inguinal hernias are the most common type of hernia. Inguinal and sports hernia have been discussed at length in recent literature, and therefore, they will not be addressed in this article. The noninguinal hernias are much less common but do occur, and knowledge of these hernias is important when assessing the athlete with abdominal pain. Approximately 25% of abdominal wall hernias are noninguinal, and new data show the order of frequency as umbilical, epigastric, incisional, femoral, and all others (i.e., Spigelian, obturator, traumatic). Return-to-play guidelines need to be tailored to the athlete and the needs of their sport. Using guidelines similar to abdominal strain injuries can be a starting point for the treatment plan. Laparoscopic repair is becoming more popular because of safety and efficacy, and it may lead to a more rapid return to play. PMID:24614421

    This review looks at the implementation of magnetic-based approaches in surgical instruments for abdominal surgeries. As abdominal surgical techniques advance toward minimizing surgical trauma, surgical instruments are enhanced to support such an objective through the exploration of magnetic-based systems. With this design approach, surgical devices are given the capabilities to be fully inserted intraabdominally to achieve access to all abdominal quadrants, without the conventional rigid link connection with the external unit. The variety of intraabdominal surgical devices are anchored, guided, and actuated by external units, with power and torque transmitted across the abdominal wall through magnetic linkage. This addresses many constraints encountered by conventional laparoscopic tools, such as loss of triangulation, fulcrum effect, and loss/lack of dexterity for surgical tasks. Design requirements of clinical considerations to aid the successful development of magnetic surgical instruments, are also discussed.

  18. [Intestinal occlusion and abdominal compartment syndrome (ACS)].

    PubMed

    Stagnitti, Franco

    2009-01-01

    Intestinal occlusion is defined as an independent predictive factor of intra-abdominal hypertension (IAH) which represents an independent predictor of mortality. Baggot in 1951 classified patients operated with intestinal occlusion as being at risk for IAH ("abdominal blow-out"), recommending them for open abdomen surgery proposed by Ogilvie. Abdominal surgery provokes IAH in 44.7% of cases with mortality which, in emergency, triples with respect to elective surgery (21.9% vs 6.8%). In particular, IAH is present in 61.2% of ileus and bowel distension and is responsible for 52% of mortality (54.8% in cases with intra-abdominal infection). These patients present with an increasing intra-abdominal pressure (IAP) which, over 20-25 mmHg, triggers an Abdominal Compartment Syndrome (ACS) with altered functions in some organs arriving at Multiple Organ Dysfunction Syndrome (MODS). The intestine normally covers 58% of abdominal volume but when there is ileus distension, intestinal pneumatosis develops (third space) which can occupy up to 90% of the entire cavity. At this moment, Gastro Intestinal Failure (GIF) can appear, which is a specific independent risk factor of mortality, motor of "Organ Failure". The pathophysiological evolution has many factors in 45% of cases: intestinal pneumatosis is associated with mucosal and serous edema, capillary leakage with an increase in extra-cellular volume and peritoneal fluid collections (fourth space). The successive loss of the mucous barrier permits a bacterial translocation which includes bacteria, toxins, pro-inflammatory factors and oxygen free radicals facilitating the passage from an intra-abdominal to inter-systemic vicious cyrcle. IAH provokes the raising of the diaphragm, and vascular and visceral compressions which induce hypertension in the various spaces with compartmental characteristics. These trigger hypertension in the renal, hepatic, pelvic, thoracic, cardiac, intracranial, orbital and lower extremity areas, giving

    Management of abdominal contusion in polytraumatized children is based on the conservative treatment of spleen and liver lesions when it is possible. Ultrasonography and CTScan can give a good evaluation of splenic, liver, pancreas or kidney lesions. In some cases, if the haemodynamic conditions are good, a non-operative treatment may be proposed.

    Because renal transplantation is allowing an increased number of patients to survive for prolonged periods, abdominal aortic aneurysms can be expected to occur with growing frequency in these patients. Surgical management of such cases involves the provision of allograft protection. To date, the literature contains 15 reports of abdominal aortic aneurysms in renal allograft recipients. We describe a 16th case and discuss the management of these patients. (Texas Heart Institute Journal 1990;17:240-4) Images PMID:15227179

A high degree of clinical suspicion, followed by appropriate diagnostic workup and therapeutic intervention, is critical, as nonoperative mortality approaches 100%. Contrary to most previously reported cases, which were associated with hemoperitoneum, we present a patient in which gastroduodenal artery dissection resulted in an organized retroperitoneal hematoma with local compression of the duodenum and subsequent bowel obstruction, resulting in vomiting, aspiration, and death.

    Computed tomography (CT) of the abdomen was performed on 46 patients who had undergone graft replacement of abdominal aortic aneurysms. Twelve post-operative complications were found in nine patients. They included hemorrhage, infection, anastomotic pseudoaneurysms, major vessel occlusion, postoperative pancreatitis, and others. The varied apperance of the normal postoperative graft is also presented. It is concluded that CT is a rapid, sensitive, and noninvasive method for detecting or excluding postoperative complications of abdominal aortic surgery.

  3. A focus on intra-abdominal infections

    PubMed Central

    2010-01-01

    Complicated intra-abdominal infections are an important cause of morbidity and are frequently associated with poor prognosis, particularly in higher risk patients. Well defined evidence-based recommendations for intra-abdominal infections treatment are partially lacking because of the limited number of randomized-controlled trials. Factors consistently associated with poor outcomes in patients with intra-abdominal infections include increased illness severity, failed source control, inadequate empiric antimicrobial therapy and healthcare-acquired infection. Early prognostic evaluation of complicated intra-abdominal infections is important to select high-risk patients for more aggressive therapeutic procedures. The cornerstones in the management of complicated intra-abdominal infections are both source control and antibiotic therapy. The timing and the adequacy of source control are the most important issues in the management of intra-abdominal infections, because inadequate and late control of septic source may have a negative effect on the outcomes. Recent advances in interventional and more aggressive techniques could significantly decrease the morbidity and mortality of physiologically severe complicated intra-abdominal infections, even if these are still being debated and are yet not validated by limited prospective trials. Empiric antimicrobial therapy is nevertheless important in the overall management of intra-abdominal infections. Inappropriate antibiotic therapy may result in poor patient outcomes and in the appearance of bacterial resistance. Antimicrobial management is generally standardised and many regimens, either with monotherapy or combination therapy, have proven their efficacy. Routine coverage especially against Enterococci and candida spp is not always recommended, but can be useful in particular clinical conditions. A de escalation approach may be recommended in patients with specific risk factors for multidrug resistant infections such as

    2013-01-01

    Background Although percutaneous posterior-ring tension-band metallic plate and percutaneous iliosacral screws are used to fix unstable posterior pelvic ring fractures, the biomechanical stability and compatibility of both internal fixation techniques for the treatment of Denis I, II and III type vertical sacral fractures remain unclear. Methods Using CT and MR images of the second generation of Chinese Digitized Human “male No. 23”, two groups of finite element models were developed for Denis I, II and III type vertical sacral fractures with ipsilateral superior and inferior pubic ramus fractures treated with either a percutaneous metallic plate or a percutaneous screw. Accordingly, two groups of clinical cases that were fixed using the above-mentioned two internal fixation techniques were retrospectively evaluated to compare postoperative effect and function. Parallel analysis was performed with a finite element model controlled trial and a case control study. Results The difference of the postoperative Majeed standards and outcome rates between two case groups was no statistically significant (P > 0.05). Accordingly, the high values of the maximum displacements/stresses of the plate-fixation model group approximated those of the screw-fixation model group. However, further simulation of Denis I, II and III type fractures in each group of models found that the biomechanics of the plate-fixation models became increasingly stable and compatible, whereas the biomechanics of the screw-fixation models maintained tiny fluctuations. When treating Denis III fractures, the biomechanical effects of the pelvic ring of the plate-fixation model were better than the screw-fixation model. Conclusions Percutaneous plate and screw fixations are both appropriate for the treatment of Denis I and II type vertical sacral fractures; whereas percutaneous plate fixation appears be superior to percutaneous screw fixation for Denis III type vertical sacral fracture.

    Sacroiliac (SI) screw fixation for unstable pelvic fractures stands out as the only minimally invasive method among all other ORIF procedures. A strictly transverse screw trajectory is needed for central or bilateral fracture patterns up to a complete iliosacroiliac fixation. However, secure screw insertion is aggravated by a narrow sacroiliac bone stock. This study investigates the influence of a highly variable sacral morphology to the existence of S1 and S2 transverse corridors. The analysis contained in this study is based on 125 CT datasets of intact human pelvises. First, sacral dysplasia was identified using the "lateral sacral triangle" method in a lateral 3-D semi-transparent pelvic view. Second, 3-D corridors for a 7.3mm screw in the upper two sacral levels were visualised using a proprietary IT workflow of custom-made programme scripts based on the Amira(®)-software. Shape-describing measurement variables were calculated as output variables. The results show a significant linear correlation between ratioT and the screw-limiting S1 isthmus height (Pearson coefficient of 0.84). A boundary ratio of 1.5 represented a positive predictive value of 96% for the existence of a transverse S1-corridor for at least one 7.3mm screw. In 100 out of 125 pelvises (80%), a sufficient S1 corridor existed, whereas in 124 specimens (99%), an S2 corridor was found. Statistics revealed significantly larger S1 and S2 corridors in males compared to females (p<0.05). However, no gender-related differences were observed for clinically relevant numbers of up to 3 screws in S1 and 1 screw in S2. The expanse of the S1 corridor is highly influenced by the dimensions of the dysplastic elevated upper sacrum, whereas the S2 corridor is not affected. Hence, in dysplastic pelvises, sacroiliac screw insertion should be recommended into the 2nd sacral segment. Our IT workflow for the automatic computation of 3-D corridors may assist in surgical pre-operative planning. Furthermore, the

    Objective: To identify the association of dietary, socioeconomic factors, sedentary behaviors and maternal nutritional status with abdominal obesity in children. Methods: A cross-sectional study with household-based survey, in 36 randomly selected census tracts in the city of Santos, SP. 357 families were interviewed and questionnaires and anthropometric measurements were applied in mothers and their 3-10 years-old children. Assessment of abdominal obesity was made by maternal and child's waist circumference measurement; for classification used cut-off points proposed by World Health Organization (1998) and Taylor et al. (2000) were applied. The association between variables was performed by multiple logistic regression analysis. Results: 30.5% of children had abdominal obesity. Associations with children's and maternal nutritional status and high socioeconomic status were shown in the univariate analysis. In the regression model, children's body mass index for age (OR=93.7; 95%CI 39.3-223.3), female gender (OR=4.1; 95%CI 1.8-9.3) and maternal abdominal obesity (OR=2.7; 95%CI 1.2-6.0) were significantly associated with children's abdominal obesity, regardless of the socioeconomic status. Conclusions: Abdominal obesity in children seems to be associated with maternal nutritional status, other indicators of their own nutritional status and female gender. Intervention programs for control of childhood obesity and prevention of metabolic syndrome should consider the interaction of the nutritional status of mothers and their children. PMID:26298655

    Abdominal aortic aneurysm (AAA) is a multifactorial disease with a strong genetic component. Since first candidate gene studies were published 20 years ago, nearly 100 genetic association studies using single nucleotide polymorphisms (SNPs) in biologically relevant genes have been reported on AAA. The studies investigated SNPs in genes of the extracellular matrix, the cardiovascular system, the immune system, and signaling pathways. Very few studies were large enough to draw firm conclusions and very few results could be replicated in another sample set. The more recent unbiased approaches are family-based DNA linkage studies and genome-wide genetic association studies, which have the potential of identifying the genetic basis for AAA, if appropriately powered and well-characterized large AAA cohorts are used. SNPs associated with AAA have already been identified in these large multicenter studies. One significant association was of a variant in a gene called CNTN3 which is located on chromosome 3p12.3. Two follow-up studies, however, could not replicate the association. Two other SNPs, which are located on chromosome 9p21 and 9q33 were replicated in other samples. The two genes with the strongest supporting evidence of contribution to the genetic risk for AAA are the CDKN2BAS gene, also known as ANRIL, which encodes an antisense RNA that regulates expression of the cyclin-dependent kinase inhibitors CDKN2A and CDKN2B, and DAB2IP, which encodes an inhibitor of cell growth and survival. Functional studies are now needed to establish the mechanisms by which these genes contribute to AAA pathogenesis. PMID:21146954

    We investigated leg-powered cycling in a recumbent tricycle for a paraplegic using functional electrical stimulation (FES) with the lumbo-sacral anterior root stimulator implant (LARSI). A female complete T9 paraplegic had a stimulator for the anterior L2 to S2 spinal roots (bilaterally) implanted in 1994. She was provided with equipment for daily FES cycling exercise at home. The cycling controller applies a pattern of stimulation in each of 16 crank angle phases. A 7-bit shaft encoder measures the crank angle with adequate precision. Each pattern was originally chosen to give the greatest propulsive force in that position when there was no motion. However, dynamically, some reduction in co-contraction is needed; also the patterns are applied with a preset advance time. Maximal power is obtained with an advance of 250 ms, which compensates for muscle response delay and accommodates changes in cadence (from about 25 to 85 rpm). With this system, she has cycled 1.2 km at a time on gently undulating road. We found that spinal root stimulation gives sufficient control over the muscles in the legs to produce a fluid cycling gait. We propose that root stimulation for leg cycling exercise may be a practicable and valuable function for paraplegics following spinal cord injury.

    This prospective study compares different clinical characteristics and outcomes of patients with two types of sacral extradural spinal meningeal cysts (SESMC) undergoing different means of surgical excision. Using the relationship between the cysts and spinal nerve roots fibers (SNRF) as seen under microscope, SESMCs were divided into two types: cysts with SNRF known as Tarlov cysts and cysts without. The surgical methods were tailored to the different types of SESMCs. The improved Japanese Orthopedic Association (IJOA) scoring system was used to evaluate preoperative and postoperative neurological function of the patients. Preoperative IJOA scores were 18.5±1.73, and postoperative IJOA scores were 19.6±0.78. The difference between preoperative and postoperative IJOA scores was statistically significant (t = -4.52, p = 0.0001), with a significant improvement in neurological function after surgery. Among the improvements in neurological functions, the most significant was sensation (z=-2.74, p=0.006), followed by bowel/bladder function (z=-2.50, p=0.01). There was a statistically significant association between the types of SESMC and the number (F=12.57, p=0.001) and maximum diameter (F=8.08, p=0.006) of the cysts. SESMC with SNRF are often multiple and small, while cysts without SNRF tend to be solitary and large. We advocate early surgical intervention for symptomatic SESMCs in view of significant clinical improvement postoperatively. PMID:24386317

    Sarcoidosis is a multisystem inflammatory disease of unknown etiology. The lungs and the lymphoid system are the most commonly involved organs. Extrapulmonary involvement is reported in 30% of patients, and the abdomen is the most common extrapulmonary site with a frequency of 50%–70%. Although intra-abdominal sarcoidosis is usually asymptomatic, its presence may affect the prognosis and treatment options. The lesions are less characteristic and may mimick neoplastic or infectious diseases such as lymphoma, diffuse metastasis, and granulomatous inflammation. The liver and spleen are the most common abdominal sites of involvement. Sarcoidosis of the gastrointestinal system, pancreas, and kidneys are extremely rare. Adenopathy which is most commonly found in the porta hepatis, exudative ascites, and multiple granulomatous nodules studding the peritoneum are the reported manifestations of abdominal sarcoidosis. Since abdominal sarcoidosis is less common and long-standing, unrecognized disease can result in significant morbidity and mortality. Imaging contributes to diagnosis and management of intra-abdominal sarcoidosis. In this report we reviewed the cross-sectional imaging findings of hepatobiliary, gastrointestinal, and genitourinary sarcoidosis. PMID:25512071

    The Rome diagnostic criteria for the functional bowel disorders and functional abdominal pain are used widely in research and practice. A committee consensus approach, including criticism from multinational expert reviewers, was used to revise the diagnostic criteria and update diagnosis and treatment recommendations, based on research results. The terminology was clarified and the diagnostic criteria and management recommendations were revised. A functional bowel disorder (FBD) is diagnosed by characteristic symptoms for at least 12 weeks during the preceding 12 months in the absence of a structural or biochemical explanation. The irritable bowel syndrome, functional abdominal bloating, functional constipation, and functional diarrhea are distinguished by symptom-based diagnostic criteria. Unspecified FBD lacks criteria for the other FBDs. Diagnostic testing is individualized, depending on patient age, primary symptom characteristics, and other clinical and laboratory features. Functional abdominal pain (FAP) is defined as either the FAP syndrome, which requires at least six months of pain with poor relation to gut function and loss of daily activities, or unspecified FAP, which lacks criteria for the FAP syndrome. An organic cause for the pain must be excluded, but aspects of the patient's pain behavior are of primary importance. Treatment of the FBDs relies upon confident diagnosis, explanation, and reassurance. Diet alteration, drug treatment, and psychotherapy may be beneficial, depending on the symptoms and psychological features.

    Background Keeping abdominal surgery patients warm is common and warming methods are needed in power outages during natural disasters. We aimed to evaluate the efficacy of low-cost, low-power warming methods for maintaining normothermia in abdominal surgery patients. Methods Patients (n = 160) scheduled for elective abdominal surgery were included in this prospective clinical study. Five warming methods were applied: heated blood transfusion/fluid infusion vs. unheated; wrapping patients vs. not wrapping; applying moist dressings, heated or not; surgical field rinse heated or not; and applying heating blankets or not. Patients’ nasopharyngeal and rectal temperatures were recorded to evaluate warming efficacy. Significant differences were found in mean temperatures of warmed patients compared to those not warmed. Results When we compared temperatures of abdominal surgery patient groups receiving three specific warming methods with temperatures of control groups not receiving these methods, significant differences were revealed in temperatures maintained during the surgeries between the warmed groups and controls. Discussion The value of maintaining normothermia in patients undergoing abdominal surgery under general anesthesia is accepted. Three effective economical and practically applicable warming methods are combined body wrapping and heating blanket; combined body wrapping, heated moist dressings, and heating blanket; combined body wrapping, heated moist dressings, and warmed surgical rinse fluid, with or without heating blanket. These methods are practically applicable when low-cost method is indeed needed. PMID:22808045

    A 31 year old male presented with high grade fever and abdominal pain of 20 days duration. At the age of 9 he had been operated on for a solitary retroperitoneal hydatid cyst and had been asymptomatic until the age of 21 when he sustained a blunt injury to the abdomen. An exploratory laparotomy for splenic rupture revealed multiple intra-abdominal hydatid cysts, which were removed. The patient remained well until the present episode. An ultrasound examination revealed multiple intra-abdominal hydatid cysts. Seven days after admission, the patient developed hydatidemesis (hydatid cysts and membranes in the vomitus) and hydatidenteria (passage of hydatid membranes in the stools), and his pain and fever subsided. A Gastrografin study and a computerized tomography (CT) scan revealed hydatid cysts communicating with the stomach and duodenum. In view of his disseminated recurrent abdominal hydatidosis, he was treated with high dose, long-term albendazole along with regular follow up. This is the first documented case of disseminated abdominal hydatidosis presenting with a cystogastric fistula and hydatidemesis.

    Recurrent abdominal pain in children is not a single condition but a description of a wide spectrum of clinical manifestations, some of which fit into a definite pattern, such as the irritable bowel syndrome, while others do not. Organic disorders may be present, but in the majority of children they cannot be detected. Although children with recurrent abdominal pain do not generally have psychological or psychiatric illness, there is a growing body of evidence to suggest that psychosocial stress plays an important role in this condition. This review will look into some of this evidence. The precise pathophysiology that results in abdominal pain is still not clearly understood, but the current belief is that visceral hypersensitivity or hyperalgesia and changes in the brain-gut axis linking the central and enteric nervous systems are important mechanisms.

    A 5-year-old Quarter Horse mare was examined because of lethargy, fever, and weight loss of 1 month's duration. Thoracic auscultation revealed decreased lung sounds cranioventrally. Thoracic ultrasonography revealed bilateral anechoic areas with hyperechoic strands, consistent with pleural effusion and fibrin tags. A large amount of free fluid was evident during abdominal ultrasonography. Abnormalities included anemia, hyperproteinemia, hyperglobulinemia, hyperfibrinogenemia, and hypoalbuminemia. Thoracic radiography revealed alveolar infiltrates in the cranial and caudoventral lung fields. A cavitary mass, consistent with an abscess, could be seen caudodorsal to the crura of the diaphragm. Ultrasonographic evaluation of this area revealed a hypoechoic mass with septations. Bilateral thoracocentesis was performed. Bacterial culture of the pleural fluid did not yield growth, but Blastomyces dermatitidis was isolated from pleural fluid, abdominal fluid, and an aspirate of the abscess. The mare was euthanatized, and a diagnosis of thoracic and abdominal blastomycosis was confirmed at necropsy. PMID:10319179

    19 children were diagnosed with abdominal cysts of different origin in the Surgical Unit of the Department of Pediatrics, Medical University of Pécs, Hungary between 2010 and 2013. The authors discuss the details of representative cases of a parovarial cyst, an intestinal duplication, and an omental cyst with emphasis on the clinical symptoms, diagnostic tools, and surgical interventions. The authors conclude that abdominal cysts often cause mild symptoms only, and they are discovered accidentally by ultrasound imaging performed for other reasons. In some cases, the cyst can cause severe complaints or even acute abdomen requiring emergency surgery. Laporoscopy may be a valuable method both in diagnosis and surgical therapy. Abdominal CT or MRI are not required in the majority of the patients.

    Sarcoidosis is a multisystem inflammatory disorder of unknown etiology. It shows a great variety of clinical presentation, organ involvement, and disease progression. Lungs and lymphoid system are the most common sites involved with a frequency of 90% and 30%, respectively. Extrapulmonary involvement of sarcoidosis is reported in 30% of patients and abdomen is the most frequent site. Furthermore, peritoneal involvement is extremely rare in sarcoidosis. The case presented here described peritoneal manifestations of sarcoidosis without involvement of lungs. A 78-year-old woman possessing signs of malignancy on blood test and abdominal magnetic resonance imaging underwent laparatomy with a suspicion of ovarian malignancy. The macroscopic interpretation during surgery was peritoneal carcinomatosis. Total abdominal hysterectomy, bilateral salpingo-oophorectomy, peritoneal biopsies, total omentectomy, and appendectomy were performed. Final histopathological result revealed the diagnosis of sarcoidosis. Clinicians must keep in mind that peritoneal sarcoidosis can mimic intra-abdominal malignancies. PMID:26558122

    Purpose InterStim device is an U.S. Food and Drug Administration approved minimal invasive therapy for sacral neuromodulation for lower urinary tract dysfunction. Before InterStim implantation, a trial with the appropriate screening tests is required to determine patient therapy eligibility. There are two different techniques for patient screening: percutaneous nerve evaluation (PNE) test and staged test. Few studies have reported success and failure rates for each technique. However, test sensitivity and predictive values of either test have not been studied. The aim of our study was to determine the sensitivity and specificity of each test and to establish a decision algorithm for the most appropriate testing method to be used as a screening test. Methods This cross-sectional study was conducted from August 2009 to February 2012 and included patients with lower urinary tract dysfunction who participated in the stimulation test trial. Patients underwent PNE as the first stimulation test, while those who encountered technical difficulty during PNE or electrode migration underwent staged testing. Results A total of 213 patients, including 172 female and 41 male subjects, underwent PNE. The patients’ diagnoses included refractory overactive bladder (47.9%), nonobstructive urinary retention (29.6%), and frequency urgency syndrome (22.1%). A total of 202 patients were screened with PNE and 10 patients with staged testing. Overall sensitivity of PNE was 87.3%, and it was 90% for staged test. PNE specificity was 98.5% as compared to 92.9% for staged test. Positive and negative predictive values for PNE were 99% and 82.1% and for staged test were 90% and 92.9%, respectively. Conclusions PNE test has high specificity and positive predictive value. We recommend PNE, a simple office-based, less expensive procedure as the first option for screening. PMID:27706006

    Background The effect of decompressive laparotomy on outcomes in patients with abdominal compartment syndrome has been poorly investigated. The aim of this prospective cohort study was to describe the effect of decompressive laparotomy for abdominal compartment syndrome on organ function and outcomes. Methods This was a prospective cohort study in adult patients who underwent decompressive laparotomy for abdominal compartment syndrome. The primary endpoints were 28‐day and 1‐year all‐cause mortality. Changes in intra‐abdominal pressure (IAP) and organ function, and laparotomy‐related morbidity were secondary endpoints. Results Thirty‐three patients were included in the study (20 men). Twenty‐seven patients were surgical admissions treated for abdominal conditions. The median (i.q.r.) Acute Physiology And Chronic Health Evaluation (APACHE) II score was 26 (20–32). Median IAP was 23 (21–27) mmHg before decompressive laparotomy, decreasing to 12 (9–15), 13 (8–17), 12 (9–15) and 12 (9–14) mmHg after 2, 6, 24 and 72 h. Decompressive laparotomy significantly improved oxygenation and urinary output. Survivors showed improvement in organ function scores, but non‐survivors did not. Fourteen complications related to the procedure developed in eight of the 33 patients. The abdomen could be closed primarily in 18 patients. The overall 28‐day mortality rate was 36 per cent (12 of 33), which increased to 55 per cent (18 patients) at 1 year. Non‐survivors were no different from survivors, except that they tended to be older and on mechanical ventilation. Conclusion Decompressive laparotomy reduced IAP and had an immediate effect on organ function. It should be considered in patients with abdominal compartment syndrome. PMID:26891380

    An 85-year-old man presented with pain and numbness in the left buttock, and physical examination revealed an approximately 7 cm mass extending from the first to the third sacral vertebrae; biopsy of the mass led to the diagnosis of CD10-negative, BCL6-weakly positive, MUM1-positive, non-germinal center (non-GC) type diffuse large B-cell lymphoma (DLBCL). Furthermore, serological testing showed negative results for Epstein-Barr virus (EBV) infection, and fluorescence in situ hybridization (FISH) revealed a MYC translocation. Radiographs showed no remarkable osteolytic bone destruction, and the patient was staged with Stage IAE. After 8 cycles of rituximab therapy and 6 cycles of CHOP therapy, complete remission has been maintained until now, approximately 1 year after the treatment. Primary sacral lymphoma is very rare, with only 6 reported cases, including the present one. A review of the reported cases revealed that the disease predominantly affects elderly men, is usually non-GC-type DLBCL and stage IAE, measures approximately 2-7 cm in diameter in general, and does not show early recurrence after chemotherapy or chemoradiotherapy. There is no report in the literature yet of primary sacral DLBCL with MYC translocation, and this is the first case report. On the other hand, 35 cases of CD10-negative DLBCL with MYC translocation, including the present one, have been reported, and a review of the reported cases showed that the disease predominantly affects Asians, middle-aged or elderly men, shows positivity for either BCL6 or MUM1 and negativity for EBV, and has a high international prognostic index and poor prognosis.

    A 74-year-old female patient, who was diagnosed with neurofibromatosis type 1 (NF1) at the age of 40, was admitted with complaints of flickering vision and gait disturbance for the last 2 years. On admission, neurological examination revealed mild bilateral hearing loss and ataxia in the limb and trunk. Laboratory tests revealed anti-hepatitis C virus (HCV) antibody positivity and elevated HCV RNA by real-time polymerase chain reaction. The cerebrospinal fluid examination revealed a slightly yellowish appearance with elevated total protein levels. Gradient echo T2*-weighted brain magnetic resonance imaging (MRI) demonstrated a rim of hypointense lesions surrounding the surface of the cerebellum, brainstem, frontal and temporal lobes, and thalamus, which was considered as hemosiderin depositions. From these MRI findings, she was diagnosed as having superficial siderosis of the central nervous system. Cerebral angiography revealed an aneurysm-like dilatation at the bifurcation of the right internal carotid-posterior communicating artery. (99m)Tc-ethyl cysteinate dimer single-photon emission computed tomography revealed hypoperfusion in the bilateral frontal and temporal lobes. Pelvic plain X-ray, pelvic computed tomography, and lumbosacral MRI revealed a sacral defect and an anterior sacral polycystic meningocele communicating with the spinal subarachnoid space. The patient's symptoms gradually worsened, and she died of septic shock because of pyelonephritis at the age of 77. An autopsy was performed; on pathological examination, we did not observe any findings associated with rupture of the aneurysm-like dilatation in the bifurcation of the right internal carotid-posterior communicating artery and cerebral amyloid angiopathy. Because duropathies-a new neurological disease concept-have been implicated as a cause of bleeding in the superficial siderosis, the anterior sacral polycystic meningocele, a type of duropathies, was presumed to be the most probable bleeding

    Objective The purpose of this study is to compare a neuroprotective effect of thoracic cord neuromodulation to that of sacral nerve neuromodulation in rat thoracic spinal cord injury (SCI) model. Methods Twenty female Sprague Dawley rats were randomly divided into 4 groups: the normal control group (n=5), SCI with sham stimulation group (SCI, n=5), SCI with electrical stimulation at thoracic spinal cord (SCI + TES, n=5), and SCI with electrical stimulation at sacral nerve (SCI + SES, n=5). Spinal cord was injured by an impactor which dropped from 25mm height. Electrical stimulation was performed by the following protocol: pulse duration, 0.1ms; frequency, 20 Hz; stimulation time, 30 minutes; and stimulation duration at thoracic epidural space and S2 or 3 neural foramina for 4 weeks. Locomotor function, urodynamic study, muscle weights, and fiber cross sectional area (CSA) were investigated. Results All rats of the SCI + TES group expired within 3 days after the injury. The locomotor function of all survived rats improved over time but there was no significant difference between the SCI and the SCI + SES group. All rats experienced urinary retention after the injury and recovered self-voiding after 3-9 days. Voiding contraction interval was 25.5±7.5 minutes in the SCI group, 16.5±5.3 minutes in the SCI+SES group, and 12.5±4.2 minutes in the control group. The recovery of voiding contraction interval was significant in the SCI + SES group comparing to the SCI group (p<0.05). Muscle weight and CSA were slightly greater in the SCI + SES than in the SCI group, but the difference was not significant. Conclusion We failed to establish a rat spinal cord stimulation model. However, sacral neuromodulation have a therapeutic potential to improve neurogenic bladder and muscle atrophy. PMID:24757451

    Abdominal wall reconstruction is a complex and challenging surgical undertaking. While permanent prosthetic mesh is considered the gold standard for minimizing hernia recurrence, placement of synthetic mesh is sometimes imprudent due to contamination or risk of infection. Acellular dermal matrices (ADM) offer an exciting biologic alternative. This article provides a historical perspective on the evolution of complex ventral hernia repair leading up to and including the placement of ADM, an explanation of the biology of ADM as it relates to ventral hernia repair, and a description of the current indications, techniques, benefits, and shortcomings of its use in the abdominal wall.

    Abdominal migraine is a rarely recognized functional intestinal disorder, manifesting as recurrent paroxysmal abdominal pain of neurogenic origin. The authors describe the 9-years old girl referred to the hospital because of chronic paroxysmal abdominal pain. She did not improve after medication used commonly in functional abdominal disorders (drotaverine, mebeverine, trimebutine). On the ground of various investigations organic causes of abdominal pain were excluded. Carefully completed anamnesis, as well as precise description of the clinical picture of abdominal pain attacks, has lead to the diagnosis of abdominal migraine. According to advice of neurologist the treatment with amitriptyline was introduced. Thereafter a significant improvement was observed. Abdominal migraine has to be taken in to account when diagnosing chronic abdominal pain in children. PMID:16245431

    2011-07-01

    Cardiopulmonary dysfunction and failure are commonly encountered in the patient with intra-abdominal hypertension (IAH) or abdominal compartment syndrome. Accurate assessment and optimization of preload, contractility, and afterload in conjunction with appropriate goal-directed resuscitation and assessment of fluid responsiveness are essential to restore end-organ perfusion. In patients with IAH, the traditional "barometric" preload indicators such as pulmonary artery occlusion pressure and central venous pressure are erroneously increased. Volumetric monitoring techniques have been proven to be superior in directing the appropriate resuscitation together with targeted abdominal perfusion pressure. If such limitations are not recognized, misinterpretation of the patient's cardiac status is likely, resulting in inappropriate and potentially detrimental therapy. IAH also markedly affects the mechanical properties of the chest wall and consequently also the respiratory function. Altered mechanical properties of the chest wall may limit ventilation, influence the work of breathing, affect the interaction between the respiratory muscles, hasten the development of respiratory failure, and interfere with gas exchange. Pulmonary monitoring is important to understand the relationships between intra-abdominal pressure and chest wall mechanics and the impact of IAH on ventilator-induced lung injury, lung distention, recruitment, and lung edema.

    Chronic abdominal pain is one of the most common clinical syndromes encountered in day to day clinical paediatric practice. Although common, its definition is confusing, predisposing factors are poorly understood and the pathophysiological mechanisms are not clear. The prevailing viewpoint in the pathogenesis involves the inter-relationship between changes in hypersensitivity and altered motility, to which several risk factors have been linked. Making a diagnosis of functional abdominal pain can be a challenge, as it is unclear which further diagnostic tests are necessary to exclude an organic cause. Moreover, large, well-performed, high-quality clinical trials for effective agents are lacking, which undermines evidence-based treatment. This Review summarizes current knowledge regarding the epidemiology, pathophysiology, risk factors and diagnostic work-up of functional abdominal pain. Finally, management options for children with functional abdominal pain are discussed including medications, dietary interventions, probiotics and psychological and complementary therapies, to improve understanding and to maximize the quality of care for children with this condition.

    Childhood obesity continues to escalate despite considerable efforts to reverse the current trends. Childhood obesity is a leading public health concern because overweight-obese youth suffer from comorbidities such as type 2 diabetes mellitus, nonalcoholic fatty liver disease, metabolic syndrome, and cardiovascular disease, conditions once considered limited to adults. This increasing prevalence of chronic health conditions in youth closely parallels the dramatic increase in obesity, in particular abdominal adiposity, in youth. Although mounting evidence in adults demonstrates the benefits of regular physical activity as a treatment strategy for abdominal obesity, the independent role of regular physical activity alone (e.g., without calorie restriction) on abdominal obesity, and in particular visceral fat, is largely unclear in youth. There is some evidence to suggest that, independent of sedentary activity levels (e.g., television watching or playing video games), engaging in higher-intensity physical activity is associated with a lower waist circumference and less visceral fat. Several randomized controlled studies have shown that aerobic types of exercise are protective against age-related increases in visceral adiposity in growing children and adolescents. However, evidence regarding the effect of resistance training alone as a strategy for the treatment of abdominal obesity is lacking and warrants further investigation.

    Abdominal compartment syndrome (ACS) is defined as an elevated intraabdominal pressure with evidence of organ dysfunction. The majority of published reports of ACS are in neonates with abdominal wall defects and in adults following trauma or burns, but it is poorly described in children. We describe the unusual presentation of an 11-year-old boy with a long history of chronic constipation who developed acute ACS requiring resuscitative measures and emergent disimpaction. He presented with a 2-week history of increasing abdominal pain, nausea, diminished appetite and longstanding encopresis. On exam, he was emaciated with a massively distended abdomen with a palpable fecaloma. Abdominal XR confirmed these findings. Within 24 hours of presentation, he became tachycardic and oliguric with orthostatic hypotension. Following two enemas, he acutely deteriorated with severe hypotension, marked tachycardia, acute respiratory distress, and a declining mental status. Endotracheal intubation, fluid boluses, and vasopressors were commenced, followed by emergent surgical fecal disimpaction. This resulted in rapid improvement in vital signs. He has been thoroughly investigated and no other condition apart from functional constipation has been identified. Although ACS secondary to constipation is extremely unusual, this case illustrates the need to actively treat constipation and what can happen if it is not. PMID:22606517

    Abstract A liposarcoma is the most common type of soft tissue sarcoma, and most liposarcomas are malignant. The extremities are the most common site for liposarcomas. There are 5 histologic types of liposarcoma, as follows: well differentiated; myxoid; round cell; pleomorphic; and dedifferentiated. Myxoid liposarcomas (MLSs) represent a subgroup of liposarcomas. There has been no report of MLSs in the abdominal wall. We report a rare case of a MLS of a 43-year-old male who presented with tensile force on the abdominal wall. Computed tomography (CT) found a tumor in abdominal wall. There was no other abnormal symptom and the laboratory testing was also unusual. At last, the tumor was successfully excised, which was diagnosed MLSs in pathology. Following standard principles, after complete excision, the patient received radiotherapy. The patient was followed up for 8 month and no disease recurrence was identified. MLSs are rarely seen in the clinic, irrespective of the presenting signs, but also based on histologic features. The aim of this report was to present the differential diagnosis of an abdominal wall mass, and to remind us of MLSs. PMID:25526446

    Background. Ectopic pregnancy is one of the leading causes of significant maternal morbidity and mortality. Abdominal surgeries increase the risk of postoperative adhesions. We here present a case of omental ectopic pregnancy in a patient with a prior history of cesarean section. Case. A 20-year-old female presented with a two-day history of crampy lower abdominal pain. Patient was hemodynamically stable with a beta HCG of 1057 mI/mL. Transvaginal ultrasound did not show an intrauterine pregnancy but revealed an ill-defined mass in the midline pelvis extending to the right of the midline. Diagnostic laparoscopy revealed large clots in the pelvis with normal uterus and adnexa. Intra-abdominal survey revealed an omental adhesion close to the right adnexa with a hematoma. Partial omentectomy was completed and the portion of the omentum with the hematoma was sent to pathology for confirmation. Final pathology confirmed the presence of chorionic villi consistent with products of conception. Conclusion. Omental ectopic pregnancy is a rare diagnosis and often missed. We recommend careful intra-abdominal survey for an ectopic pregnancy in the presence of hemoperitoneum with normal uterus and adnexa. This can be safely achieved using laparoscopy in early gestational ages when the patient is hemodynamically stable. PMID:25478262

    Blunt abdominal traumas are uncommonly encountered despite their high prevalence, and injuries to the organ like duodenum are relatively uncommon (occurring in only 3%-5% of abdominal injuries) because of its retroperitoneal location. Duodenal injury combined with gastric perforation from a single abdominal trauma impact is rarely heard. The aim of this case report is to present a rare case of blunt abdominal trauma with combined gastric and duodenal injuries. PMID:25738037

    Lateral abdominal wall muscles in children and adolescents have not been characterised to date. In the present report, we examined the reliability of the ultrasound measurement and thickness of the oblique external muscle (OE), oblique internal muscle (OI) and transverse abdominal muscle (TrA) at rest and during abdominal drawing-in manoeuvre (ADIM) on both sides of the body in healthy adolescents. We also determined possible differences between boys and girls and defined any factors-such as body mass, height and BMI-that may affect the thickness of the abdominal muscles. B-mode ultrasound was used to assess OE, OI and TrA on both sides of the body in the supine position. Ultrasound measurements at rest and during ADIM were reliable in this age group (ICC3,3 > 0.92). OI was always the thickest and TrA the thinnest muscle on both sides of the body. In this group, an identical pattern of the contribution of the individual muscles to the structure of the lateral abdominal wall (OI > OE > TrA) was observed. At rest and during ADIM, no statistically significant side-to-side differences were demonstrated in either gender. The body mass constitutes between 30% and <50% of the thickness differences in all muscles under examination at rest and during ADIM. The structure of lateral abdominal wall in adolescents is similar to that of adults. During ADIM, the abdominal muscles in adolescents react similarly to those in adults. This study provided extensive information regarding the structure of the lateral abdominal wall in healthy adolescents.

    Although minimally invasive approaches to the abdominal cavity are becoming increasingly more important, open surgical techniques are still of essential interest and must be mastered by general and visceral surgeons. The choice of the particular approach depends on the specificity and location of the scheduled procedure. The following article is intended to give an overview on the current literature as well as experiences in the field of open surgical approaches to the abdominal cavity.

    Abstract Purpose: Purpose of this study was to evaluate the long term efficacy of repetitive sacral root magnetic stimulation (rSMS) in patients with monosymptomatic nocturnal enuresis (MNE). Methods: Forty four patients were randomized to receive either sham or real repetitive sacral root magnetic stimulation (rSMS; 15 Hz with a total of 1500 pulses/session) for 10 sessions. Evaluation was performed before starting treatment, immediately after the 5th and 10th treatment session, and 1 month later, using frequency of enuresis/week, visual analogue scale (VAS) and quality of life as outcome measures. Resting and active motor thresholds of gastrocnemius muscles were measured before and after the end of sessions. Results: Both treatment and control groups were comparable for baseline measures of frequency of enuresis, and VAS. The mean number of wet nights/week was significantly reduced in patients who received real rSMS. This improvement was maintained 1 month after the end of treatment. Patients receiving real-rSMS also reported an improvement in VAS ratings and quality of life. A significant reduction of resting motor threshold was recorded after rSMS in the real group while no such changes were observed in the sham group. Conclusion: These findings suggest that rSMS has potential as an adjuvant treatment for MNE and deserves further study. PMID:26409403

    Early detection of non blanching erythema (pressure ulcer category I) is necessary to prevent any further skin damage. An objective method to discriminate between blanching/non blanching erythema is presently not available. The purpose of this investigation was to explore if a non invasive objective method could differentiate between blanching/non blanching erythema in the sacral area of patients undergoing hip fracture surgery. Seventy-eight patients were included. The sacral area of all patients was assessed using (i) conventional finger-press test and (ii) digital reading of the erythema index assessed with reflectance spectrophotometry. The patients were examined at admission and during 5 days postsurgery. Reflectance spectrophotometry measurements proved able to discriminate between blanching/non blanching erythema. The reliability, quantified by the intra-class correlation coefficient, was excellent between repeated measurements over the measurement period, varying between 0·82 and 0·96, and a significant change was recorded in the areas from day 1 to day 5 (P < 0·0001). The value from the reference point did not show any significant changes over the same period (P = 0·32). An objective method proven to identify early pressure damage to tissue can be a valuable tool in clinical practice.

    Introduction Low back pain is a common cause of medical consultation, and usually supposes a non-malignant prognostic. Presentation of case We report an atypical appearance of low back pain associated to shock and pulsatile abdominal mass that made us diagnose an abdominal aortic aneurysm as reason of vertebral lysis and pain. Discusion Surgical repair of contained AAA should be directed to secondary re-rupture prevention, with an approximate survival near to 100% at selected patients for elective surgery. Consequently, orthopedic surgery for back spine stabilization has to be elective in those cases when vertebral destruction is above 30% and clinic is directly related to spine instability. Conclusion We should consider AAA as other cause of low back pain and routinely examine the abdomen and seek complementary imaging proves when risk factors for AAA are present. PMID:25569196

    To carry out an abdominal ultrasound examination with the highest degree of accuracy and thoroughness, it is essential to have a good knowledge of the anatomy and the normal measurements of the different organs. In this way, we can determine their normal condition and identify the pathology and its location more easily. It is very important to adopt a correct examination procedure, systematically sweeping the scan in the same direction and not leaving any organ unexamined. We suggest a procedure consisting of longitudinal, cross-sectional and oblique scans to view all the abdominal organs, starting the examination in the epigastric region, scanning first the right upper quadrant, then the left upper quadrant, both iliac fossa, and lastly the hypogastric region.

    Solitary fibrous tumors (SFTs) are uncommon neoplasms of mesenchymal origin that usually arise from the pleura. SFTs of the abdominal wall are extremely rare, and only 12 cases have been reported in the English language literature. This report presents a new case of SFT of the abdominal wall in a 74-year-old female. Positron emission tomography demonstrated the heterogeneous 18F-fluorodeoxyglucose uptake of the tumor (the maximum standardized uptake value was 2.8). Histologically, the mitotic count was 1 to 2/10 high-power fields. The patient is alive without recurrence at 10 months after undergoing a surgical excision. We discuss the clinicopathological features and differential diagnosis and present a review of the pertinent literature.

    Two cases illustrate the clinical manifestations and angiographic findings associated with segmental stenosis of the abdominal aorta. Such lesions represent the chronic occlusive stage of Takayasu's disease, a nonspecific inflammatory arteritis of uncertain etiology. While the disease is considered autoimmune, an infectious process may be involved. Complications typically associated with stenotic lesions of the abdominal aorta are secondary renal hypertension and ischemic symptoms secondary to vascular insufficiency. Surgical correction, the treatment of choice, has achieved excellent results for these well-localized lesions. Secondary renal hypertension was relieved by a spenorenal shunt and the disease has since been controlled with conservative management in the first patient. An aortofemoral bypass graft successfully alleviated the vascular insufficiency in the second patient, although the patient unfortunately expired from a refractory postoperative cardiac complication.

    Alterations of the abdominal aorta are relatively common, particularly in older people. Technological advances in the fields of ultrasonography, computed tomography, angiography, and magnetic resonance imaging have greatly increased the imaging options for the assessment of these lesions. Because it can be done rapidly and is also non-invasive, ultrasonography plays a major role in the exploration of the abdominal aorta, from its emergence from the diaphragm to its bifurcation. It is indicated for the diagnosis and follow-up of various aortic diseases, especially aneurysms. It can be used to define the shape, size, and location of these lesions, the absence or presence of thrombi and their characteristics. It is also useful for monitoring the evolution of the lesion and for postoperative follow-up. However, its value is limited in surgical planning and in emergency situations. PMID:23396814

    10 patients with adrenal damage were observed during 2.5 years. It amounted 0.93% of all patients with closed abdominal injuries. The right adrenal gland was traumatized in all cases evidently due to it's compression between right lobe of liver and vertebral column. Adrenal damage is observed quite often in combination with injuries of right liver lobe, right kidney and retroperitoneal hematoma formation. 5 patients underwent laparotomy on account of intra-abdominal bleeding, but adrenal damage was never revealed. Ultrasound and tomographic semiotics of adrenal damage was worked out, which allowed ascertaining diagnosis in 80% on application of ultrasound study and in 100% at computer tomography. Injury of one adrenal gland was not accompanied by adrenal failure and did not require hormonal replacement therapy.

    Abdominal and pelvic calcifications are usually incidental findings and require further measures to determine their origin. Most laboratory investigations are of little help. Plain anteroposterior and lateral x-rays are essential. The time of appearance and localisation of a calcification is of diagnostic importance. Amorphous, granular and irregular calcification can be an early sign of malignancy. Mobility of a calcification also helps to clarify its origin. Over the past 15 years abdominal and pelvic calcifications, excluding urological radiodensities, have been found in 63 patients up to fourteen years of age at our institute. A migrating deposit in the omentum, a spontaneously amputated calcified ovary mimicking a vesical calculus and a congenital retroperitoneal xanthofibroma caused the greatest difficulty in establishing a preoperative diagnosis.

    Lymphoceles may occur as a result of lymphatic injury during abdominal aortic surgery. These lymphatic collections may occur as a retroperitoneal mass or as groin lymphoceles. Four cases are presented in which persistent retroperitoneal lymphoceles were discovered 2 to 8 years after surgery. Reexploration of the groin and repeated aspirations of lymphatic fluid failed to control the drainage. Reexploration of the retroperitoneum documented lymphatic injury, which was controlled by ligation of the lymphatics with suture. A review of the literature discloses five similar reported cases of retroperitoneal lymphocele and 12 cases of chylous ascites after abdominal aortic surgery. Clearly, avoiding lymphatic injury or immediate repair of any lymphatic injuries will prevent this problem. Once a persistent lymphocele has developed, aspiration will establish the diagnosis. Our experience would suggest that reexploration of the retroperitoneum is required to control the drainage and to prevent possible graft infection.

    Gravity of abdominal vessels traumatisms is secondary to multiple factors. It depends on the type of injured vessels, aetiology and associated lesions. Between September 1984 and March 1995, 22 abdominal vessel traumatisms in 16 patients (mean age: 39 years) were treated. At surgical exploration, 4 aortic and 2 renal vein lesions, 7 iliac artery and 3 renal artery contusions, 2 superior mesenteric artery dissections; 3 infra-renal vena cava ruptures and 1 superior mesenteric vein dilaceration were found. All lesions were caused by penetrant wounds secondary to firearm or blade injury or secondary to injuries due to ski or traffic accidents. In 5 cases, lesions were iatrogenic. There was no mortality in the post-operative period, 14 patients out of the 16 patients operated on have been followed during a period from 1 to 120 months.

    The independent relationships between visceral and abdominal sc adipose tissue (AT) depots, muscle composition, and insulin sensitivity were examined in 40 abdominally obese, premenopausal women. Measurements included glucose disposal by euglycemic clamp, muscle composition by computed tomography, abdominal and nonabdominal (e.g. leg) AT by magnetic resonance imaging and cardiovascular fitness. Glucose disposal rates were negatively related to visceral AT mass (r = -0.42, P < 0.01). These observations remained significant (P < 0.01) after control for nonabdominal and abdominal sc AT, muscle attenuation, and peak oxygen uptake. Total, abdominal, or leg sc AT or muscle attenuation was not significantly (P > 0.10) related to glucose disposal. Subdivision of abdominal sc AT into anterior and posterior depots did not alter the observed relationships. Further analysis matched two groups of women for abdominal sc AT but with low and high visceral AT. Women with high visceral AT had lower glucose disposal rates compared with those with low visceral AT (P < 0.05). A similar analysis performed on two groups of women matched for visceral AT but high and low abdominal sc AT revealed no statistically different values for insulin sensitivity (P > 0.10). In conclusion, visceral AT alone is a strong correlate of insulin resistance independent of nonabdominal, abdominal sc AT, muscle composition, and cardiovascular fitness. Subdivision of abdominal sc AT did not provide additional insight into the relationship between abdominal obesity and metabolic risk.

    The authors analyse 125 cases of vaginal histerectomy (V.H.) preceded by vaginal and abdominal operations (15.3% of a total of 817 V.H.) There were 95 cases of previous abdominal operations and 30 cases of previous gynecological operations (19 vaginal and 11 abdominal). The most frequent previously performed vaginal operation was anterior and posterior colporrhaphy. The authors have come to the conclusion that neither previous abdominal nor previous gynecological surgical interventions make the carrying out of vaginal histerectomy more difficult. Only Doleris's operation, among abdominal ones, may represent a relative contraindication for V.H. In one case the authors had to complete the already started histerectomy abdominally owing to some technical difficulties. The authors maintain that it would be good to use vaginal histerectomy more frequently after previously applied gynecological, vaginal, and abdominal operations.

    Focal epilepsy with ictal abdominal pain is an unusual partial epilepsy characterized by paroxysmal episodes of abdominal or visceral pain, disturbance of awareness and electroencephalographic abnormalities. We describe a new case of ictal abdominal pain in which gastrointestinal complaints were the only manifestation of seizures and review the previously described pediatric patients. In our patient clinical findings, ictal EEG abnormalities, and a good response to antiepileptic drugs allowed us to make a diagnosis of focal epilepsy with ictal abdominal pain. This is a rare epileptic phenomenon that should be suspected in patients with unexplained paroxysmal abdominal pain and migraine-like symptoms. We suggest that, after the exclusion of more common etiologies, focal epilepsy with ictal abdominal pain should be considered in patients with paroxysmal abdominal pain and ictal EEG abnormalities.

    Endovascular repair of abdominal aortic aneurysms is an important technique in the vascular surgeon's armamentarium, which has created a seismic shift in the management of aortic pathology over the past two decades. In comparison to traditional open repair, the endovascular approach is associated with significantly improved perioperative morbidity and mortality. The early survival benefit of endovascular abdominal aortic aneurysm repair is sustained up to 3 years postoperatively, but longer-term life expectancy remains poor regardless of operative modality. Nonetheless, most abdominal aortic aneurysms are now repaired using endovascular stent grafts. The technology is not perfect as several postoperative complications, namely endoleak, stent-graft migration, and graft limb thrombosis, can develop and therefore lifelong imaging surveillance is required. In addition, a postoperative inflammatory response has been documented after endovascular repair of aortic aneurysms; the clinical significance of this finding has yet to be determined. Subsequently, the safety and applicability of endovascular stent grafts are likely to improve and expand with the introduction of newer-generation devices and with the simplification of fenestrated systems.

    Abdominal multi-organ transplantation including the liver, gallbladder, spleen, pancreas, kidneys, adrenal glands and gastrointestinal tract was attempted in 8 dogs. Each experiment was discontinued when the recipient deteriorated. Immersion hypothermia was introduced in both the donor and recipient until the esophageal temperature reached 27-30 degrees C. Whole abdominal organs of the donor were removed in an en-bloc fashion at 20 degrees C of the graft temperature after additional cooling by ice slush scattering into the abdominal cavity. Transplantation was carried out orthotopically in the following sequence: (1) the proximal aorta, (2) suprahepatic vena cava, (3) distal aorta, (4) infrahepatic vena cava. The alimentary tract was reconstructed by gastro-gastrostomy and colo-colostomy. The ureters were implanted in the bladder. Cold ischemic time of the graft was about 40 minutes. Heparin was not used throughout the procedure. Five out of eight dogs were alive for more than 24 hours and two of them survived for 60 hours with good recovery. No immunosuppressant was given. Though the result in the present study was far from satisfaction, the experiment may provide a possibility of a new experimental model for transplantation, especially regarding pathophysiology and interrelationship of the transplanted complex organs.

    Most abdominal aortic aneurysms are asymptomatic, being accidentally found on physical examination or in routinely performed imaging studies. They only require surveillance (which is variable according to the aneurism size) and medical therapy in order to achieve risk factor reduction. However, in certain situations, according to the risk of aneurism rupture, elective surgery or endovascular procedure may be necessary. About 80% of the cases of aneurism rupture occur into the retroperitoneal space, with a high mortality rate. There are uncommon presentations of aneurism rupture as the aorto-caval fistula, which also require fast diagnosis and intervention. The authors present the case of a 71-year-old man, with the previous diagnosis of hypertension, acute myocardial infarction 2 months earlier (undergone primary Percutaneous Coronary Intervention) and tabagism, who was admitted at the emergency department with intense 24-hour-evolution epigastric pain. On physical examination, the Blood Pressure values measured at the lower limbs were about half the ones measured at the upper limbs and there was an abdominal pulsatile mass, with a high-intensity murmur. As the authors suspected aortic dissection, aneurysm, coarctation or thrombosis, it was done a Computed Tomography scanning with intravenous contrast, which revealed a ruptured abdominal aorta aneurysm with a mural thrombus. The doppler ultrasound confirmed the presence of a high debit aorto-caval fistula. The patient was immediately transferred to the Vascular Surgery. However he died 2 hours later, during surgery.

    Background: A new closure technique is introduced, which uses strips of macroporous polypropylene mesh as a suture for closure of abdominal wall defects due to failures of standard sutures and difficulties with planar meshes. Methods: Strips of macroporous polypropylene mesh of 2 cm width were passed through the abdominal wall and tied as simple interrupted sutures. The surgical technique and surgical outcomes are presented. Results: One hundred and seven patients underwent a mesh sutured abdominal wall closure. Seventy-six patients had preoperative hernias, and the mean hernia width by CT scan for those with scans was 9.1 cm. Forty-nine surgical fields were clean-contaminated, contaminated, or dirty. Five patients had infections within the first 30 days. Only one knot was removed as an office procedure. Mean follow-up at 234 days revealed 4 recurrent hernias. Conclusions: Mesh sutured repairs reliably appose tissue under tension using concepts of force distribution and resistance to suture pull-through. The technique reduces the amount of foreign material required in comparison to sheet meshes, and avoids the shortcomings of monofilament sutures. Mesh sutured closures seem to be tolerant of bacterial contamination with low hernia recurrence rates and have replaced our routine use of mesh sheets and bioprosthetic grafts. PMID:27757361

  12. Quantification of abdominal aortic deformation after EVAR

    Quantification of abdominal aortic deformation is an important requirement for the evaluation of endovascular stenting procedures and the further refinement of stent graft design. During endovascular aortic repair (EVAR) treatment, the aortic shape is subject to severe deformation that is imposed by medical instruments such as guide wires, catheters, and, the stent graft. This deformation can affect the flow characteristics and morphology of the aorta which have been shown to be elicitors for stent graft failures and be reason for reappearance of aneurysms. We present a method for quantifying the deformation of an aneurysmatic aorta imposed by an inserted stent graft device. The outline of the procedure includes initial rigid alignment of the two abdominal scans, segmentation of abdominal vessel trees, and automatic reduction of their centerline structures to one specified region of interest around the aorta. This is accomplished by preprocessing and remodeling of the pre- and postoperative aortic shapes before performing a non-rigid registration. We further narrow the resulting displacement fields to only include local non-rigid deformation and therefore, eliminate all remaining global rigid transformations. Finally, deformations for specified locations can be calculated from the resulting displacement fields. In order to evaluate our method, experiments for the extraction of aortic deformation fields are conducted on 15 patient datasets from endovascular aortic repair (EVAR) treatment. A visual assessment of the registration results and evaluation of the usage of deformation quantification were performed by two vascular surgeons and one interventional radiologist who are all experts in EVAR procedures.

    Transversus abdominal plane (TAP) block is a known and useful technique, widely used for postoperative pain management of abdominal wall incisions. During the past years, and following the expansion of ultrasound guided techniques, its use has even gained more adepts. It is usually used as an adjuvant technique, primarily in order to control postoperative pain and reduce opioids consumption. We report the case of an 82 years old patient admitted for drainage of a postoperative abdominal wall hematoma after correction of a McBurney incisional hernia. The corrective surgery had gone on without incident, under general anesthesia with laryngeal mask. Two weeks later, the patient came back to our emergency department with a clear hematoma of the abdominal wall. Surgery was decided. A sole local anesthetic technique was achieved, using a TAP block. The block was performed under ultrasound guidance, using a subcostal approach. The surgery went on without complications. Therefore, TAP block offers a hemodynamic stability, appropriate intra-operative anesthesia and post-surgical analgesia of the abdominal wall.

    Introducción: la presión intraabdominal es el estado de equilibrio de la presión de la cavidad abdominal en reposo y puede presentar cambios durante la ventilación mecánica o espontánea. El objetivo fue determinar la presión intraabdominal como predictor de cirugía en el paciente con dolor abdominal agudo. Métodos: se llevó a cabo un estudio de casos y controles anidado en una cohorte de pacientes con dolor abdominal agudo en el servicio de urgencias de un hospital de segundo nivel, en el periodo comprendido entre abril y diciembre de 2013. Se incluyeron 37 pacientes, todos fueron intervenidos quirúrgicamente con previa toma de la presión intraabdominal. Se formaron los grupos con el resultado del estudio anatomopatológico: con evidencia de proceso inflamatorio abdominal agudo (n = 28) y sin evidencia de proceso inflamatorio abdominal agudo (n = 9). Resultados: en los casos el 100 % presentó presión intraabdominal alta con una p = 0.01, RM: 5 (IC 95 %: 2.578-9.699). En los casos la media de la presión intraabdominal fue de 11.46 y en los controles de 9.2 (p = 0.183). Conclusiones: el dolor abdominal que requiere cirugía para su resolución tiene relación directa con una presión intraabdominal > 5 mmHg.

    Abdominal compliance (AC) is an important determinant and predictor of available workspace during laparoscopic surgery. Furthermore, critically ill patients with a reduced AC are at an increased risk of developing intra-abdominal hypertension and abdominal compartment syndrome, both of which are associated with high morbidity and mortality. Despite this, AC is a concept that has been neglected in the past.AC is defined as a measure of the ease of abdominal expansion, expressed as a change in intra-abdominal volume (IAV) per change in intra-abdominal pressure (IAP):AC = ΔIAV / ΔIAPAC is a dynamic variable dependent on baseline IAV and IAP as well as abdominal reshaping and stretching capacity. Whereas AC itself can only rarely be measured, it always needs to be considered an important component of IAP. Patients with decreased AC are prone to fulminant development of abdominal compartment syndrome when concomitant risk factors for intra-abdominal hypertension are present.This review aims to clarify the pressure-volume relationship within the abdominal cavity. It highlights how different conditions and pathologies can affect AC and which management strategies could be applied to avoid serious consequences of decreased AC.We have pooled all available human data to calculate AC values in patients acutely and chronically exposed to intra-abdominal hypertension and demonstrated an exponential abdominal pressure-volume relationship. Most importantly, patients with high level of IAP have a reduced AC. In these patients, only small reduction in IAV can significantly increase AC and reduce IAPs.A greater knowledge on AC may help in selecting a better surgical approach and in reducing complications related to intra-abdominal hypertension.

    Chronic perineal pain limits patients in physical and sexual activities, leading to social and psychological distress. In most cases, this pain develops after surgery in the urogenital area or as a consequence of trauma. Neuromodulation is one of the options in chronic postsurgical perineal pain treatment. We present a case of refractory perineal pain after right sided surgical resection of a Bartholin's cyst which was treated with third sacral nerve root/dorsal root ganglion stimulation using the transforaminal approach. We describe a new anchorless lead placement technique using a unique curved lead delivery sheath. We postulate that this new posterior foraminal technique of lead placement is simple, safe, and reversible and may lower the occurrence of lead related complications. PMID:27123351

    Amniotic band syndrome is a rare congenital disorder caused by entrapment of fetal parts by fibrous amniotic bands in utero. The congenital anomalies seen in this syndrome vary widely and defects may be isolated or multiple and do not follow a specific pattern. Asymmetric distribution of defects is the hallmark of this syndrome. The diagnosis is difficult to make on ultrasound and relies on identification of amniotic bands. We report a case of amniotic band syndrome with sacral agenesis diagnosed on routine antenatal ultrasound scan in the second offspring of a recently diagnosed diabetic mother. The associated features were entrapment of umbilical cord, caudal adhesions and lower limb anomalies. Medical termination of pregnancy was done and all the fetal anomalies as well as umbilical cord abnormalities were confirmed. The importance of meticulous scanning to evaluate for amniotic bands and the umbilical cord in addition to the fetal structures is emphasized. PMID:25926929

    Blunt abdominal trauma may cause severe intra-abdominal injuries, while clinical findings could be mild or absent directly after the trauma. The absence of clinical findings could mislead physicians into underestimating the severity of the injury at the primary survey, and inevitably leads to a delay in the diagnosis. The Blunt Abdominal Trauma in Children (BATiC) score may help to identify children who are at a high risk for intra-abdominal injuries in an early stage and requires additional tests directly. A case of a 10-year-old girl with a duodenal perforation after a blunt abdominal trauma is presented. A delay in diagnosis may lead to an increased morbidity and mortality rate. A low admission threshold for children with abdominal pain after a blunt trauma is recommended. PMID:26698210

  19. The role of antidepressants in the treatment of abdominal obesity.

    PubMed

    Rosmond, R; Björntorp, P

    2000-06-01

    The pathophysiology of abdominal obesity is unclear and controversial. Recent evidence now suggests that inadequate cortisol secretion is associated with abnormalities in glucose, insulin and lipid metabolism, including hypertension, bringing the importance of the hypothalamic-pituitary-adrenal (HPA) axis in the pathogenesis of abdominal obesity to the forefront. In addition, abnormal gonadal steroid concentrations and impaired plasma growth hormone levels accompany the abdominally obese state. Since the reproductive and growth axes are inhibited at many levels by various components of the HPA axis, increasing cortisol levels results in further depression of testosterone and growth hormone concentrations. Over the last decade, antidepressant (serotoninergic) drugs have proved useful as equalizers of HPA axis hyperactivity. Such therapy may interrupt the vicious circle of a hyperactive HPA axis leading to increasing abdominal obesity and endocrine perturbations that, in turn, leads to progressive accumulation of abdominal fat. Additionally, preliminary results indicate that serotoninergic agents decrease abdominal fat mass with improvements in related risk factors.

  20. Functional Abdominal Pain: "Get" the Function, Loose the Pain.

    2015-07-01

    Functional abdominal pain is a mind-body, psychosocial, and self-reinforcing experience with significant consequences for the sufferer and the surrounding support network. The occurrence of unpredictable symptoms and their severity add an element of dread and feeling out-of-control to daily life and often reduce overall functioning in a downward spiral. Two clinical presentations of functional abdominal pain are offered in this article (composites to protect confidentiality) dealing with abdominal pain syndrome and abdominal migraines. The treatment demonstrates the use of hypnotic principles for self-regulation, exploration, and meaning-making. Hypnosis treatment is conducted in combination with mindfulness-based interventions and Traditional Chinese Medicine's (TCM) teachings regarding abdominal health and illness. The clinical examples illustrate medical findings that suggest children with early life stress and an early onset of gastrointestinal somatization may not simply outgrow their functional abdominal pain but may suffer into adulthood.

    The natural course of many abdominal aortic aneurysms (AAA) is to gradually expand and eventually rupture and monitoring the disease progression is essential to their management. In this publication, we review surrogate markers of AAA progression. AAA diameter remains the most widely used and important marker of AAA growth. Standardized reporting of reproducible methods of measuring AAA diameter is essential. Newer imaging assessments, such as volume measurements, biomechanical analyses, and functional and molecular imaging, as well as circulating biomarkers, have potential to add important information about AAA progression. Currently, however, there is insufficient evidence to recommend their routine use in clinical practice. PMID:26715680

    Serious spinal cord ischemia may follow infrarenal abdominal aortic surgery. Five cases are summarized and added to the 23 previously published cases in order to identify this syndrome, emphasize its importance, and draw attention to the possibility of spontaneous recovery which may occur. The multifactorial complex which comprises each patient's clinical picture clouds a precise and specific cause for paraplegia in these cases. However, neither hypotension, steal phenomena nor emboli are necessary for completion of the syndrome. The relevant spinal cord arterial anatomy indicates that the common anomalies which occur favor development of spinal cord ischemia in the arteriosclerotic population which requires aortic surgery. No means of prevention is possible at this time.

    Gastritis, as gastric and duodenal ulcer, is associated with epigastric abdominal pain, influenced by meals, associated with nausea and vomiting and weight loss. Diagnosis s based upon upper gastrointestinal fibre endoscopy that allows direct visualisation of gastric lesions and realization of antral and fundic biopsies for anatomopathology and culture. Main etiologies are drug induced, stress and H. pylori infection. Looking for H. pylori is only justified in those children presenting with digestive symptoms requiring upper gastrointestinal endoscopy. Therefore non invasive test are only indicated for control of eradication. Treatment of H. pylori infection associates proton pump inhibitors and two antibiotics for 7 to 10 days.

    The most common complications after CSF shunting to treat hydrocephalus are shunt infection and obstruction. Although ventriculoperitoneal (VP) diversion of the CSF using artificial shunt devices is an accepted method for the management of hydrocephalus, high rates of various complications have been reported, ranging from 24% to 47%. Among these, abdominal complications account for approximately 25%. The incidence of bowel perforation by shunt-catheter is known to be as low as 0.1-0.7%. We describe a case of migration af a peritoneal catheter through a congenital hernia of Morgagni.

    A 35-year-old man was delivered to the emergency room complaining of right flank pain because of blunt abdominal trauma sustained while playing baseball. Enhanced computed tomography (CT) revealed a right adrenal mass and fluid collection around the mass. We diagnosed the mass as pheochromocytoma by endocrinological examination and radioisotopical imaging test. After absorption of the hematoma three months after the injury, laparoscopic right adrenalectomy was performed. He had an uncomplicated postoperative course without supplementation of catecholamine. Pathological findings were compatible with pheochromocytoma. Eight months after the operation, he had no evidence of recurrence.

    Large posterior abdominal masses, particularly those in the right upper abdomen, may be difficult to localize correctly into the peritoneal or retroperitoneal compartments. The following signs were found to be reliable CT indicators of retroperitoneal location: obliteration of the perinephric fat outlining the psoas muscle; lateral displacement of the fat outlining the posterior right lobe of the liver; rotation of the intrahepatic portal veins to the left; anterior displacement of the inferior vena cava and renal veins; and anterior displacement of the ascending colon, descending duodenum, or pancreatic head.

    Purpose. To compare costs and reimbursements for three different treatments for uterine fibroids. Methods. Costs and reimbursements were collected and analyzed from the Thomas Jefferson University Hospital decision support database from 540 women who underwent abdominal hysterectomy (n 299), abdominal myomectomy (n = 105), or uterine fibroid embolization (UFE) (n = 136) for uterine fibroids during 2000-2002. We used the chi-square test and ANOVA, followed by Fisher's Least Significant Difference test, for statistical analysis. Results. The mean total hospital cost (US$) for UFE was $2,707, which was significantly less than for hysterectomy ($5,707) or myomectomy ($5,676) (p < 0.05). The mean hospital net income (hospital net reimbursement minus total hospital cost) for UFE was $57, which was significantly greater than for hysterectomy (-$572) or myomectomy (-$715) (p < 0.05). The mean professional (physician) reimbursements for UFE, hysterectomy, and myomectomy were $1,306, $979, and $1,078, respectively. Conclusion. UFE has lower hospital costs and greater hospital net income than abdominal hysterectomy or abdominal myomectomy for treating uterine fibroids. UFE may be more financially advantageous than hysterectomy or myomectomy for the insurer, hospital, and health care system. Costs and reimbursements may vary amongst different hospitals and regions.

    INTRODUCTION Pulmonary sequestration (PS) is an extremely rare malformation defined as a portion of lung tissue isolated from the pulmonary system. PSs are classified into intralobar type and intra-abdominal PS that represents only 2.5% of cases. There are 20 cases of PS reported in adults and only two were managed by laparoscopic approach. We report a case of intra-abdominal PS mimicking a gastroesophageal duplication cyst in an adult. Besides its rarity, this is the first intra-abdominal PS in an adult managed by an anterior laparoscopic approach. PRESENTATION OF CASE A 60-year-old female patient had had epigastric and left upper quadrant pain for several days. Physical examination was normal. Image test were consistent with a gastroesophageal duplication. The patient was taken to the operating room for laparoscopic exploration and resection. The pathological diagnosis was extralobar pulmonary sequestration. DISCUSSION Less than 20 cases of PS have been reported in adults and only two cases were managed by a lateral laparoscopic approach. In contrast to these reports, we used an anterior approach due to the GEJ suspected origin of the mass. CONCLUSION Extralobar intra-abdominal PS is an extremely rare condition during adulthood but this diagnosis should be included in the differential diagnosis of a left-sided suprarenal mass. Due to the difficulty in achieving a definitive preoperative diagnosis, surgery is recommended. Laparoscopic resection is safe and effective but careful preoperative imaging studies are recommended in order to plan the most suitable approach. PMID:24091075

    Prevalence of abdominal migraine (AM) and recurrent abdominal pain (RAP) was evaluated in patients who visited Hikita Pediatric Clinic between May 2010 and April 2015. Patient data were collected prospectively using a questionnaire. Out of a total of 3611 cases, observed prevalence was 2.44% for repeated abdominal pain over a period of ≥3 months, 1.47% for RAP, and 0.19% for AM. Duration of abdominal pain was longer for AM than for non-AM RAP. Certain clinical features were significantly different between AM and non-AM RAP. No correlations were found among age at onset, frequency of attack, and duration of attack for various types of RAP. It was difficult to determine useful diagnostic criteria for distinguishing between AM and non-AM RAP. They did not appear to be separate disease entities but, instead, lie on a disease spectrum. The present prevalence of AM (0.19%) was lower than that in many previous studies from countries other than Japan. PMID:27460403

    In most cases a ruptured abdominal aortic aneurism is dramatic, with rapid deterioration of the clinical condition of the patient. With abdominal and back pain, pulsatile tumour, and development of bleeding shock the diagnosis is obvious. In some cases the symptoms are not clear and the condition can be misinterpreted. The authors describe a case to illustrate this. A 74 year-old male was admitted to hospital with vague abdominal pain and left inguinal hernia. It later turned out that a ruptured abdominal aortic aneurism was the reason for his symptoms and signs. 14 similar cases are reported in the literature. PMID:8332976

    The abdominal pseudocyst is an unfrequent complication in patients with ventriculoperitoneal shunts. Although many cases have been reported in children, it is rare in adult patients. However, a 47-year-old man with congenital hydrocephalus who had been treated with ventriculoperitoneal shunt since the age of three months, was admitted to hospital due to abdominal pain. He was eventually diagnosed radiologically as having an abdominal pseudocyst. Despite this complication being rare, especially in adults, it should be highly suspected whenever an abdominal cyst co-occurs with a ventriculoperitoneal shunt.

    An intra-abdominal bronchogenic cyst (BC) is a very rare congenital anomaly caused by abnormal budding of the developing tracheobronchial tree. Intra-abdominal BCs are reported as retroperitoneal masses in most cases, many of which are located on the left side of the midline, the perigastric area, the left adrenal gland, or the superior body of the pancreas. Intra-abdominal BCs are frequently misdiagnosed due to the rarity, location, and variable cystic content. We report five patients with intra-abdominal BCs who underwent surgery in a single institution.

    1982-07-01

    Subjective feelings of fatigue were assessed before operation and 10, 20 and 30 days after uncomplicated elective abdominal surgery in 16 otherwise healthy patients, using a constructed fatigue scale model. In addition, all patients had an orthostatic stress test performed at the same times. Six of the patients also underwent a bicycle ergometer test measuring heart rate and oxygen consumption. Subjective feelings of fatigue were increased (P less than 0.01) at all three postoperative observations, and only 5 of 16 patients returned to their preoperative level. The increased subjective feeling of fatigue correlated positively (RS = 0.53, P less than 0.001) with the increased pulse rate seen during orthostatic stress after operation. Heart rate was about 5 per cent higher (n.s.) after operation when bicycling at the same work loads, while oxygen consumption decreased by about 2 per cent (P less than 0.01) at all three postoperative bicycle tests. It is concluded that even electric uncomplicated abdominal surgery is followed by a pronounced feeling of fatigue, which may persist 1 month after surgery in about one-third of patients. The fatigue scale model seems applicable for future studies on the pathogenesis and treatment of the postoperative fatigue syndrome.

    1975-01-01

    Two patients with aortic abdominal aneurysms in association with horseshoe kidney are presented, making a total of 34 cases recorded in the literature. In 29 patients, the aneurysm was resected and five patients were non-resectable. Because of the abnormalities in vascular supply to the abnormal kidney, it is important to diagnose the combination of aneurysm and horseshoe kidney preoperatively. An error in diagnosis should be unusual if an intravenous pyelogram is routinely obtained on all patients. This study may reveal abnormalities which will allow the diagnosis of horseshoe kidney to be made or suspected. If the intravenous pyelogram is abnormal, it should be followed by an aortogram. This may substantiate the diagnosis of aneurysm and horseshoe kidney and provide the necessary detailed information regarding the pattern of blood supply and its relationship to functioning tissue. The amount and disposition of functioning renal parenchyma may be further amplified by renal scan. If this sequence is followed, the unanticipated combination of abdominal aneurysm and horseshoe kidney should be rare. PMID:1130850

    Non-invasive surface registration methods have been developed to register and track breathing motions in a patient's abdomen and thorax. We evaluated several different registration methods, including marker tracking using a stereo camera, chessboard image projection, and abdominal point clouds. Our point cloud approach was based on a time-of-flight (ToF) sensor that tracked the abdominal surface. We tested different respiratory phases using additional markers as landmarks for the extension of the non-rigid Iterative Closest Point (ICP) algorithm to improve the matching of irregular meshes. Four variants for retrieving the correspondence data were implemented and compared. Our evaluation involved 9 healthy individuals (3 females and 6 males) with point clouds captured in opposite breathing phases (i.e., inhalation and exhalation). We measured three factors: surface distance, correspondence distance, and marker error. To evaluate different methods for computing the correspondence measurements, we defined the number of correspondences for every target point and the average correspondence assignment error of the points nearest the markers.

    Consecutive patients undergoing emergency appendectomy (283) or urgent cholecystectomy (51) were prospectively studied for the development of post-operative incisional or peritoneal sepsis. Severity of the original peritoneal infection was carefully recorded, while use of a Penrose dam to drain the peritoneum was randomized according to pre-assigned hospital number. Both aerobic and anaerobic cultures were taken from the abdomen at the time of operation as well as from all postoperative infectious foci. Results demonstrated no essential differences in incidence of wound and peritoneal infection following appendectomy for simple or suppurative appendicitis (187) or following cholecystectomy for acute cholecystitis (51). However, with gangrenous or perforative appendicitis (94), incisional and intra-abdominal infection rates were 43% and 45%, respectively, when a drain was used; yet only 29 and 13%, respectively, without a drain. These latter differences were significant (p < 0.001). In addition, intra-abdominal abscesses were three times as likely to drain through the incision than along any tract provided by the rubber conduit. Cultures revealed that hospital pathogens accounted for a greater proportion of wound and peritoneal sepsis after cholecystectomy and appendectomy for simple or suppurative appendicitis if a drain had been inserted than if managed otherwise. By contrast, a mixed bacterial flora was responsible for most infections following appendectomy for gangrenous or perforated appendicitis, irrespective as to use of a drain. PMID:646499

    Background: Problems regarding bowel elimination are quite common in patients undergoing abdominal surgery. Objectives: To determine constipation risk before the surgery, bowel elimination during postoperative period, and the factors affecting bowel elimination. Patients and Methods: This is a cross-sectional study. It was conducted in a general surgery ward of a university hospital in Zonguldak, Turkey between January 2013 and May 2013. A total of 107 patients were included in the study, who were selected by convenience sampling. Constipation Risk Assessment Scale (CRAS), patient information form, medical and nursing records were used in the study. Results: The mean age of the patients was found to be 55.97 ± 15.74 (year). Most of the patients have undergone colon (37.4%) and stomach surgeries (21.5%). Open surgical intervention (83.2%) was performed on almost all patients (96.3%) under general anesthesia. Patients were at moderate risk for constipation with average scores of 11.71 before the surgery. A total of 77 patients (72%) did not have bowel elimination problem during postoperative period. The type of the surgery (P < 0.05), starting time for oral feeding after the surgery (P < 0.05), and mobilization (P < 0.05) were effective on postoperative bowel elimination. Conclusions: There is a risk for constipation after abdominal surgery. Postoperative practices are effective on the risk of constipation. PMID:26380107

  3. Ultrasound Screening for Abdominal Aortic Aneurysm

    PubMed Central

    2006-01-01

    Executive Summary Objective The aim of this review was to assess the effectiveness of ultrasound screening for asymptomatic abdominal aortic aneurysm (AAA). Clinical Need Abdominal aortic aneurysm is a localized abnormal dilatation of the aorta greater than 3 cm. In community surveys, the prevalence of AAA is reported to be between 2% and 5.4%. Abdominal aortic aneurysms are found in 4% to 8% of older men and in 0.5% to 1.5% of women aged 65 years and older. Abdominal aortic aneurysms are largely asymptomatic. If left untreated, the continuing extension and thinning of the vessel wall may eventually result in rupture of the AAA. Often rupture may occur without warning, causing acute pain. Rupture is always life threatening and requires emergency surgical repair of the ruptured aorta. The risk of death from ruptured AAA is 80% to 90%. Over one-half of all deaths attributed to a ruptured aneurysm take place before the patient reaches hospital. In comparison, the rate of death in people undergoing elective surgery is 5% to 7%; however, symptoms of AAA rarely occur before rupture. Given that ultrasound can reliably visualize the aorta in 99% of the population, and its sensitivity and specificity for diagnosing AAA approaches 100%, screening for aneurysms is worth considering as it may reduce the incidence of ruptured aneurysms and hence reduce unnecessary deaths caused by AAA-attributable mortality. Review Strategy The Medical Advisory Secretariat used its standard search strategy to retrieve international health technology assessments and English-language journal articles from selected databases to determine the effectiveness of ultrasound screening for abdominal aortic aneurysms. Case reports, letters, editorials, nonsystematic reviews, non-human studies, and comments were excluded. Questions asked: Is population-based AAA screening effective in improving health outcomes in asymptomatic populations? Is AAA screening acceptable to the population? Does this affect the

    Five patients who had undergone renal transplantation 3 months to 23 years ago were operated on successfully for an abdominal aortic aneurysm. In the first case, dating from 1973, the kidney was protected by general hypothermia. In the remaining patients, no measure was used to protect the kidney. Only one patient showed a moderate increase of blood creatinine in the postoperative period; renal function returned to normal in 15 days. All five patients have normal renal function 6 months to 11 years after aortic repair. Results obtained in this series show that protection of the transplant during aortic surgery is not necessary, provided adequate surgical technique is used. Such a technique is described in detail. Its use simplifies surgical treatment of such lesions and avoids the complex procedures employed in the seven previously published cases. Images FIGS. 1A and B. FIGS. 2A and B. FIGS. 3A and B.

We firmly believe that ultrasound done to «bedside» the patient by the family doctor, can greatly complement the physical examination and greatly improve clinical effectiveness, allowing the browser an immediate view of the anatomy and physiology of certain structures. It is within this context is particularly relevant ultrasonography of the Aorta and large abdominal vessels, made by the family doctor or the emergency itself, which will develop along this chapter.

    Abdominal vascular syndromes are rare diseases. Although such syndromes vary widely in terms of symptoms and etiologies, certain imaging findings are characteristic. Depending on their etiology, they can be categorized as congenital-including blue rubber bleb nevus syndrome, Klippel-Trenaunay syndrome, and hereditary hemorrhagic telangiectasia (Rendu-Osler-Weber syndrome)-or compressive-including "nutcracker" syndrome, median arcuate ligament syndrome, Cockett syndrome (also known as May-Thurner syndrome), and superior mesenteric artery syndrome. In this article, we aimed to illustrate imaging findings that are characteristic of these syndromes, through studies conducted at our institution, as well as to perform a brief review of the literature on this topic.

    Remnant malignant tissue is left behind after conventional surgery for an unresectable intraperitoneal malignant tumor. Standard radiotherapy or chemotherapy rarely enables good tumor control. We report the case of a 74-year-old man who developed a local recurrence of a sigmoid tumor located 5 to 6 cm from the anus. The tumor was fixed to the pelvic wall and could not be totally eradicated with conventional surgery. Preoperative peroperative assessment confirmed the absence of metastatic spread. Radiotherapy could not be performed due to risk of bowel injury. Peroperative radiofrequency ablation was followed by surgical colorectal resection without restoration of intestinal continuity, leaving only tumor tissue destroyed by radiofrequency. No adjuvant treatment was proposed because of intolerance to chemotherapy. Clinical assessment and thoracic and abdominal CT scan confirmed the absence of recurrence 26 months after radiofrequency ablation. Serum markers remained normal.

    Background Impalement injury is an uncommon presentation in the emergency department (ED), and penetrating thoraco-abdominal injuries demand immediate life-saving measures and prompt care. Massive penetrating trauma by impalement in a pediatric case represents a particularly challenging presentation for emergency providers in non-trauma center settings. Case presentation We report a case of 10 year old male who presented in our ED with an alleged history of fall from an approximately 15 foot tall coconut tree, landing over an upright bamboo stake approximately 50 centimeter long, resulting in a trans-abdomino, trans-thoracic injury. In addition to prompt resuscitation and hospital transfer, assessment of damage to vital structures in conjunction with surgical specialty consultation was an immediate goal. Conclusion This article describes a case study of an impalement injury, relevant review of the available literature, and highlights the peculiar strategies required in the setting of a resource limited ED.

    Objectives The purpose of this study was to review radiological images of patients with Paragonimus westermani (PW) that simultaneously involved the chest and abdomen. Methods Our study included four patients with serologically and histopathologically confirmed paragonimiasis. Abdomen CT (n=3) and chest CT (n=3) scans were available, and abdominal wall ultrasonography was performed in all patients. We retrospectively reviewed the clinical, radiological and histopathological findings of these patients. Results The most common abdominal CT findings were ascites and intraperitoneal or abdominal wall nodules. Low-attenuated serpentine lesions of the liver were another common and relatively specific feature. Conclusion Radiologists should consider the possibility of PW when these abdominal CT findings are noted, especially with pleural effusion or subpleural nodules in patients with initial abdominal symptoms.

    Penetrating abdominal trauma has been traditionally treated by exploratory laparotomy. Nowadays laparoscopy has become an accepted practice in hemodynamically stable patient without signs of peritonitis. We report a case of a lower anterior abdominal gunshot patient treated laparoscopically. A 32-year-old male presented to the Emergency Department with complaint of gunshot penetrating injury at left lower anterior abdominal wall. The patient had no symptoms or obvious bleeding and was vitally stable. On examination we identified 1 cm diameter entry wound at the left lower abdominal wall. The imaging studies showed the bullet in the peritoneal cavity but no injured intraperitoneal and retroperitoneal viscera. We decided to remove the bullet laparoscopically. Twenty-four hours after the intervention the patient was discharged. The decision for managing gunshot patients should be based on clinical and diagnostic findings. Anterior abdominal injuries in a stable patient without other health problems can be managed laparoscopically. PMID:27525150

    Introduction Desmoid tumors are rare lesions without any metastatic potential but a strong tendency to invade locally and to recur. These tumors are associated with women of fertile age, especially during and after pregnancy. Case presentation The case of a desmoid tumor of the anterior abdominal wall in a 40-year-old Caucasian man with no relevant family history is presented, describing its appearance on computed tomography and ultrasonography. The patient, who presented with a painless mass in the left anterolateral abdomen, had a history of previous urgent abdominal surgery after a shotgun injury two years earlier. Radical resection of the affected abdominal wall musculature was performed, and the defect was reconstructed with polypropylene mesh. Conclusion The diagnosis of desmoid tumor should be strongly considered even in male patients with an abdominal mass and a history of previous abdominal surgery. The goal of its treatment is complete tumor excision and avoidance of the development of complications such as hernia. PMID:21787413

    The aim of this study was to assess the pattern of abdominal masses and evaluate the value of ultrasound in paediatric abdominal masses. We used a cross-sectional study of abdominal masses in children attending a university teaching hospital. The common abdominal masses were: Wilms' tumour, 12 (14.8%); lymphoma, 11 (13.6%); appendiceal mass/abscess, 11 (13.6%); neuroblastoma, 7 (8.6%); TB, 6 (7.4%); hydronephrosis, 5 (6.2%); abdominal wall abscess, 6 (7.4%); hydatidcyst, 4 (4.9%); mesenteric cyst, 3 (3.7%); and intussusceptions, 3 (3.7%). Identification of a purely cystic mass was suggestive of benign lesion (odds ratio [OR] = 118, P = 0.0001) and masses found in the <5 years age group tend to be malignant (OR = 2.77). The most common sites of origin were kidneys, retroperitoneal extra renal and gastrointestinal tract. The overall diagnostic accuracy of ultrasound was 88.9%.

    Abdominal pathology in the critically ill or injured patient frequently leads to the use of open abdominal techniques or the actual performance of abdominal surgery in the ICU. All individuals responsible for the care of patients in the ICU should be familiar with the concepts and techniques of open abdomen wound management. ICU bedside abdominal surgery may be indicated if the patient is too unstable for transport to the operating room and the surgeon believes a limited procedure, such as a decompression of IAH, will be life-saving. Smaller procedures are also feasible, such as intra-abdominal packing changes for which the operating room is unnecessary. Development of a successful Surgery Outside the Operating Room program depends on mature cooperation between the surgeons and other professional ICU staff. Logistic details of such a program should be discussed and a scheduling protocol should be prepared before an emergent need for bedside surgery.

    The purpose of this study was to develop a valid, reliable and accurate system of measurement of abdominal aortic aneurysms, using volumetric analysis of x-ray computed tomographic data. This study evaluates illustrative cases, and compares measurements of AAA phantoms, using standard 2D versus volumetric methods. To validate the volumetric analysis, four phantom aneurysms were constructed in a range of diameters (4.5 - 7.0 cm) which presents the greatest management challenge to the clinician. These phantoms were imaged using a Toshiba Xpress SX helical CT. Separate scans were obtained at conventional (10 mm X 10 mm) and thin slice (5 mm X 5 mm) collimations. The thin slices were reconstructed at 2 mm intervals. Data from each of the 96 scans were interpreted using a standard 2D approach, then analyzed using task-oriented volumetric software. We evaluate patient assessments, and compare greatest outer diameters of phantoms, by standard versus volumetric methods. Qualitative differences between solutions based on standard versus volumetric analysis of illustrative patient cases are substantial. Expert radiologists' standard measurements of phantom aneurysms are highly reliable (r2 equals 0.901 - 0.958; p < 0.001), but biased toward significant overestimation of aneurysm diameters in the range of clinical interest. For the same phantoms, volumetric analysis was both more reliable (r2 equals 0.986 - 0.996; p < 0.001), and more accurate, with no significant bias in the range of interest. Volumetric analysis promotes selection of more valid management strategies, by providing vital information not otherwise available, and allowing more reliable and accurate assessment of abdominal aortic aneurysms. It is particularly valuable in the presence of aortic tortuosity, vessel eccentricity, and uncertain involvement of critical vessels.

    Abdominal aortic aneurysm is a common condition that may be lethal when it is unrecognized. Current guidelines suggest repair as the aneurysm diameter reaches 5.0 to 5.5 cm. Most aortic aneurysms are detected incidentally when imaging is done for other purposes or through screening programs. Ninety percent of these aneurysms are below the threshold for intervention at the time of detection. A number of studies have sought to determine factors that lead to progression of aneurysmal disease that might be amenable to intervention during this period of observation. We review these studies and make recommendations for the medical management of small abdominal aortic aneurysms. On the basis of our current knowledge of the causes of aneurysm, a number of approaches have been proposed to prevent progression of aneurysmal disease. These include hemodynamic management, inhibition of inflammation, and protease inhibition. The American College of Cardiology/American Heart Association clinical practice guidelines rules of evidence have helped to define strength of evidence to support these approaches. Level A evidence (from large randomized trials) is available to indicate that observation of small aneurysms in men is safe up to a size of 5.5 cm and that propranolol does not inhibit aneurysm expansion. Level B evidence (from small randomized trials) suggests that roxithromycin or doxycycline will decrease the rate of aneurysm expansion. A number of studies agree that tobacco use is associated with an increased rate of aneurysm expansion. Level B and C evidence is available to suggest that 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors (statins) may inhibit aneurysm expansion. There are animal data but no human data demonstrating that angiotensin-converting enzyme inhibitors or losartan, an angiotensin receptor blocker, will decrease the rate of AAA expansion. A pharmacological agent without important side effects that inhibited aneurysm expansion could change

    The ability to accurately measure subcutaneous adipose tissue (SAT) and visceral adipose tissue (VAT) from images is important for improved assessment and management of patients with various conditions such as obesity, diabetes mellitus, obstructive sleep apnea, cardiovascular disease, kidney disease, and degenerative disease. Although imaging and analysis methods to measure the volume of these tissue components have been developed [1, 2], in clinical practice, an estimate of the amount of fat is obtained from just one transverse abdominal CT slice typically acquired at the level of the L4-L5 vertebrae for various reasons including decreased radiation exposure and cost [3-5]. It is generally assumed that such an estimate reliably depicts the burden of fat in the body. This paper sets out to answer two questions related to this issue which have not been addressed in the literature. How does one ensure that the slices used for correlation calculation from different subjects are at the same anatomic location? At what anatomic location do the volumes of SAT and VAT correlate maximally with the corresponding single-slice area measures? To answer these questions, we propose two approaches for slice localization: linear mapping and non-linear mapping which is a novel learning based strategy for mapping slice locations to a standardized anatomic space so that same anatomic slice locations are identified in different subjects. We then study the volume-to-area correlations and determine where they become maximal. We demonstrate on 50 abdominal CT data sets that this mapping achieves significantly improved consistency of anatomic localization compared to current practice. Our results also indicate that maximum correlations are achieved at different anatomic locations for SAT and VAT which are both different from the L4-L5 junction commonly utilized.

    This is a single center retrospective review of abdominal or abdomino-thoracic penetrating wounds treated between 2004 and 2013 in the gastrointestinal and emergency unit of the university hospital of Grenoble, France. This study did not include patients who sustained blunt trauma or non-traumatic wounds, as well as patients with penetrating head and neck injury, limb injury, ano-perineal injury, or isolated thoracic injury above the fifth costal interspace. In addition, we also included cases that were reviewed in emergency department morbidity and mortality conferences during the same period. Mortality was 5.9% (11/186 patients). Mean age was 36 years (range: 13-87). Seventy-eight percent (145 patients) suffered stab wounds. Most patients were hemodynamically stable or stabilized upon arrival at the hospital (163 patients: 87.6%). Six resuscitative thoracotomies were performed, five for gunshot wounds, one for a stab wound. When abdominal exploration was necessary, laparotomy was chosen most often (78/186: 41.9%), while laparoscopy was performed in 46 cases (24.7%), with conversion to laparotomy in nine cases. Abdominal penetration was found in 103 cases (55.4%) and thoracic penetration in 44 patients (23.7%). Twenty-nine patients (15.6%) had both thoracic and abdominal penetration (with 16 diaphragmatic wounds). Suicide attempts were recorded in 43 patients (23.1%), 31 (72.1%) with peritoneal penetration. Two patients (1.1%) required operation for delayed peritonitis, one who had had a laparotomy qualified as "negative", and another who had undergone surgical exploration of his wound under general anesthesia. In conclusion, management of clear-cut or suspected penetrating injury represents a medico-surgical challenge and requires effective management protocols. PMID:27318585

    We examined the independent relationships among various visceral and abdominal subcutaneous adipose tissue (AT) depots, glucose tolerance, and insulin sensitivity in 89 obese men. Measurements included an oral glucose tolerance test (OGTT), glucose disposal by euglycemic clamp, and abdominal and nonabdominal (e.g., peripheral) AT by magnetic resonance imaging (MRI). OGTT glucose and glucose disposal rates were related (P < 0.05) to visceral AT (r = 0.50 and -0.41, respectively). These observations remained significant (P < 0.05) after control for nonabdominal and abdominal subcutaneous AT, and maximal O(2) consumption (VO(2 max)). Abdominal subcutaneous AT was not a significant correlate (P > 0.05) of any metabolic variable after control for nonabdominal and visceral AT and VO(2 max). Division of abdominal subcutaneous AT into deep and superficial depots and visceral AT into intra- and extraperitoneal AT depots did not alter the observed relationships. Further analysis matched two groups of men for abdominal subcutaneous AT but also for low and high visceral AT. Men with high visceral AT had higher OGTT glucose values and lower glucose disposal rates compared with those with low visceral AT values (P < 0.05). A similar analysis performed on two groups of men matched for visceral AT but also for high and low abdominal subcutaneous AT revealed no statistically different values for any metabolic variable (P > 0.10). In conclusion, visceral AT alone is a strong correlate of insulin resistance independent of nonabdominal and abdominal subcutaneous AT and cardiovascular fitness. Subdivision of visceral and abdominal subcutaneous AT by MRI did not provide additional insight into the relationship between abdominal obesity and metabolic risk in obese men.

    There is growing interest in measuring intra-abdominal pressure (IAP) in postsurgical and critically ill patients because increased pressure can impair various organs and functions. The aim of this study was to evaluate the effect of different IAP levels on the postoperative renal function of subjects undergoing orthotopic liver transplantation. IAP was measured every 8 hours with the urinary bladder pressure method for at least 72 hours after surgery. At the end of the study, the patients were classified on the basis of their IAP values: < or = 18 mm Hg (group A), 19 to 24 mm Hg (group B), > or = 25 mm Hg (group C). The three groups were compared in terms of the incidence of acute renal failure (defined as blood creatinine > 1.5 mg/dL or an increase in the same of > 1.1 mg/dL within 72 hours of surgery), hourly diuresis, blood creatinine, the filtration gradient, hemodynamic variations, and outcome. The incidence of renal failure was higher among the subjects in group C (P < .05 versus group A and < .01 versus group B), who also had higher creatinine levels (P < .01), a greater need for diuretics (P < .01) and a worse outcome (P < .05). Receiver Operator Characteristic curve analysis showed that an abdominal pressure of 25 mm Hg had the best sensitivity/specificity ratio for renal failure. An intra-abdominal pressure of > or = 25 mm Hg is an important risk factor for renal failure in subjects undergoing liver transplant.

    Intra-abdominal hypertension (IAH) is an important contributor to early organ dysfunction among patients with trauma and sepsis. However, the impact of increased intra-abdominal pressure (IAP) among pediatric, pregnant, non-septic medical patients, and those with severe acute pancreatitis (SAP), obesity, and burns has been studied less extensively. The aim of this review is to outline the pathophysiologic implications and treatment options for IAH and abdominal compartment syndrome (ACS) for the above patient populations. We searched MEDLINE and PubMed to identify relevant studies. There is an increasing awareness of IAH in general medicine. The incidence of IAH and, to a lesser extent, ACS is high among patients with SAP. IAH should always be suspected and IAP measured routinely. In children, normal IAP in mechanically ventilated patients is approximately 7 ± 3 mm Hg. As an IAP of 10-15 mm Hg has been associated with organ damage in children, an IAP greater than 10 mm Hg should be considered IAH in these patients. Moreover, as ACS may occur in children at an IAP lower than 20 mm Hg, any elevation in IAP higher than 10 mm Hg associated with new organ dysfunction should be considered ACS in children until proven otherwise. Monitor IAP trends and be aware that specific interventions may need to be instituted at lower IAP than the current ACS definitions accommodate. Finally, IAH and ACS can occur both in abdominal trauma and extra-abdominal trauma patients. Early mechanical hemorrhage control and the avoidance of excessive fluid resuscitation are key elements in preventing IAH in trauma patients. IAH and ACS have been associated with many conditions beyond the general ICU patient. In adults and in children, the focus should be on the early recognition of IAH and the prevention of ACS. Patients at risk for IAH should be identified early during their treatment (with a low threshold to initiate IAP monitoring). Appropriate actions should be taken when IAP increases

    A number of population groups in Latin America show high prevalences of stunting (low height-for-age) despite very low rates of wasting (weight-for-height deficits). One possible explanation for this phenomenon is an increase in abdominal circumference, which would affect children's weights but not their heights. This study was designed to describe the abdominal circumferences of a group of poor children from Northeast Brazil, and to relate these to their weight-for-weight z-score. Children (n = 252) participating in a government growth monitoring program were studied. The prevalence of stunting (below -2 SD) was 26.2%, but only 1.2% were wasted. Abdominal circumferences increased with age up to 36 mo, followed by a slight decline after 48 mo. Abdominal circumference was the anthropometric measurement most closely associated with weight-for-height, with a coefficient of determination of 41%. Even after adjusting for arm circumference, abdominal circumference continued to explain 16% of the variation in weight-for-height. Despite slight differences in measurement techniques, the study children had consistently larger abdominal girths than a sample of North American children. These findings must be verified by replication but highlight a possible contribution of abdominal circumference in the determination of levels of wasting.

    Background: Abdominal wall, one of the most commonly transplanted composite tissues, is less researched and lacking animal models. Its clinical necessities were emphasized in multiple case series to reconstruct large abdominal defects. Previous animal models have only studied components of the abdominal wall transplant. We describe findings from a new model that more likely reflect clinical transplantation. Methods: Full-thickness hemiabdominal wall flap was procured from Brown Norway (BN) rats and transplanted to an orthotopic defect on Lewis rats. Three groups were studied: group 1: Lewis to Lewis syngeneic; group 2: BN to Lewis control; and group 3: BN to Lewis with postoperative cyclosporine. Vascular imaging and cross vessel section were performed along with full-thickness abdominal wall. Immune cell profiling with flow cytometry at different time points was studied in all groups. Results: Syngeneic group had no rejection. Control group consistently showed rejection around postoperative day 6. With cyclosporine treatment, however, transplant and recipient tissue integration was observed. Flow cytometry revealed that innate immunity is responsible for the initial inflammatory events following abdominal wall engraftment. Adaptive immunity cells, specifically interferon-γ-producing T helper (Th) 1 and interleukin-17-producing Th17 cells, dramatically and positively correlate with rejection progression of abdominal wall transplants. Conclusions: Technical, histological, and immunological aspects of a new rat model are described. These results give clues to what occurs in human abdominal wall transplantation. In addition, Th1, a proinflammatory cell, was found to be a potential biomarker for allograft rejection. PMID:25289329

    With the developments in medical technology and increased surgical experience, advanced laparoscopic surgical procedures are performed successfully. Laparoscopic abdominal surgery is one of the best examples of advanced laparoscopic surgery (LS). Today, laparoscopic abdominal surgery in general surgery clinics is the basis of all abdominal surgical interventions. Laparoscopic abdominal surgery is associated with systemic and splanchnic hemodynamic alterations. Inadequate splanchnic perfusion in critically ill patients is associated with increased morbidity and mortality. The underlying pathophysiological mechanisms are still not well understood. With experience and with an increase in the number and diversity of the resulting data, the pathophysiology of laparoscopic abdominal surgery is now better understood. The normal physiology and pathophysiology of local and systemic effects of laparoscopic abdominal surgery is extremely important for safe and effective LS. Future research projects should focus on the interplay between the physiological regulatory mechanisms in the splanchnic circulation (SC), organs, and diseases. In this review, we discuss the effects of laparoscopic abdominal surgery on the SC. PMID:25561784

    Background Configuration of the abdominal aorta is related to healthy aging and a variety of disorders. Objectives We aimed to assess heritable and environmental effects on the abdominal aortic diameter. Methods 114 adult (69 monozygotic, 45 same-sex dizygotic) twin pairs (mean age 43.6 ± 16.3 years) underwent abdominal ultrasound with Esaote MyLab 70X ultrasound machine to visualize the abdominal aorta below the level of the origin of the renal arteries and 1-3 cm above the bifurcation. Results Age- and sex-adjusted heritability of the abdominal aortic diameter below the level of the origin of the renal arteries was 40% [95% confidence interval (CI), 14 to 67%] and 55% above the aortic bifurcation (95% CI, 45 to 70%). None of the aortic diameters showed common environmental effects, but unshared environmental effects were responsible for 60% and 45% of the traits, respectively. Conclusions Our analysis documents the moderate heritability and its segment-specific difference of the abdominal aortic diameter. The moderate part of variance was explained by unshared environmental components, emphasizing the importance of lifestyle factors in primary prevention. Further studies in this field may guide future gene-mapping efforts and investigate specific lifestyle factors to prevent abdominal aortic dilatation and its complications. PMID:26559855

    We performed a comparative study between abdominal and vaginal hysterectomies using clinical data from Al-Jamhouria hospital (one of the largest maternity hospitals in Eastern Libya). Various parameters were taken into consideration: the rates of each type (and their subtypes); average age of patients; indications; causes; postoperative complications; and duration of stay in the hospital afterwards. Conclusions and recommendations were drawn from the results of this study. In light of the aforementioned parameters, it was found that: (1) abdominal hysterectomies were more common than vaginal hysterectomies (p < 0.001); (2) patients admitted for abdominal hysterectomies are younger than those admitted for vaginal hysterectomies (p < 0.001); (3) the most common indication for an abdominal hysterectomy was menstrual disturbances, while for vaginal hysterectomies it was vaginal prolapse; (4) the histopathological cause for abdominal and vaginal hysterectomies were observed and the most common were found to be leiomyomas and atrophic endometrium; (5) there was no significant difference between the two routes in terms of postoperative complications; (6) patients who were admitted for abdominal hysterectomies spent a longer amount of time in the hospital (p < 0.01). It was concluded that efforts should be made to further pursue vaginal and laparoscopic hysterectomies as a viable option to the more conventional abdominal route.

    Background: Abdominal injuries contribute significantly to battlefield trauma morbidity and mortality. This study sought to determine the incidence, demographics, clinical features, spectrum, severity, management, and outcome of abdominal trauma during a civilian conflict. Materials and Methods: A prospective analysis of patients treated for abdominal trauma during the Jos civil crises between December 2010 and May 2012 at the Jos University Teaching Hospital. Results: A total of 109 victims of communal conflicts with abdominal injuries were managed during the study period with 89 (81.7%) males and 20 (18.3%) females representing about 12.2% of the total 897 combat related injuries. The peak age incidence was between 21 and 40 years (range: 3–71 years). The most frequently injured intra-abdominal organs were the small intestine 69 (63.3%), colon 48 (44%), and liver 41 (37.6%). Forty-four (40.4%) patients had extra-abdominal injuries involving the chest in 17 (15.6%), musculoskeletal 12 (11%), and the head in 9 (8.3%). The most prevalent weapon injuries were gunshot 76 (69.7%), explosives 12 (11%), stab injuries 11 (10.1%), and blunt abdominal trauma 10 (9.2%). The injury severity score varied from 8 to 52 (mean: 20.8) with a fatality rate of 11 (10.1%) and morbidity rate of 29 (26.6%). Presence of irreversible shock, 3 or more injured intra-abdominal organs, severe head injuries, and delayed presentation were the main factors associated with mortality. Conclusion: Abdominal trauma is major life-threatening injuries during conflicts. Substantial mortality occurred with loss of nearly one in every 10 hospitalized victims despite aggressive emergency room resuscitation. The resources expenditure, propensity for death and expediency of timing reinforce the need for early access to the wounded in a concerted trauma care systems. PMID:26957819

    The diagnosis of intra-abdominal abscess by radiographic means often relies on combining the results of several different imaging modalities. Computed tomography (CT) has been shown to be a safe, accurate and rapid diagnostic method of diagnosing these abscesses. Five patients with a variety of intra-abdominal abscesses are presented in whom the CT scan alone provided the correct diagnosis. The various imaging modalities available for the radiologic diagnosis of intra-abdominal abscess are described and are compared to CT diagnosis regarding their pitfalls.

This patient had a failed previous vaginal cerclage. An abdominal cerclage was performed at the time of abdominal myomectomy. A subsequent pregnancy was diagnosed, with ruptured membranes at 19 weeks' gestation, and the patient opted for pregnancy termination. After laparoscopic removal of the cerclage, cervical laminaria were placed, and the patient underwent an uncomplicated dilation and curettage procedure the following day. PMID:23743392

    1978-02-01

    The purpose of this study was to compare ultrasonic measurements of fetal abdominal circumference to ultrasonic measurements of fetal biparietal diameter, as a means of estimating fetal body weight. Of 58 fetuses who had abdominal circumferences measured, 48 (82%) of the predicted weights were within 15% of the actual birth weights. Forty-four of the same 58 fetuses had satisfactory biparietal diameter measurements, but only 21 (48%) of the predicted weights were within 15% of the actual birthweights. Ultrasonic measurement of abdominal circumference appears to be a more reliable index of fetal body weight than other currently available techniques.

    OBJECTIVE Comprehensive assessment of abdominal hemodynamics is crucial for many clinical diagnoses but is challenged by a tremendous complexity of anatomy, normal physiology, and a wide variety of pathologic abnormalities. This article introduces 4D flow MRI as a powerful technique for noninvasive assessment of the hemodynamics of abdominal vascular territories. CONCLUSION Four-dimensional flow MRI provides clinicians with a more extensive and straightforward approach to evaluate disorders that affect blood flow in the abdomen. This review presents a series of clinical cases to illustrate the utility of 4D flow MRI in the comprehensive assessment of the abdominal circulation. PMID:27187681

    Eight patients, six men and two women (mean age 67.3 years) were treated for infrarenal abdominal aortic aneurysm by endovascular technique. A bifurcated graft (Mialhe Stentor, Min Tec, France) was used in all cases. The introducing system, with an 18 French diameter, is inserted through an arteriotomy in the common femoral artery. The proximal end of the main part of the graft is placed just distal to the renal arteries, and includes one graft limb, which is placed in the iliac artery on the ipsilateral side. The contralateral graft limb is introduced into a short limb of the main graft through a 10 French introducer, using Seldinger-technique, from the contralateral common femoral artery. All the implantations were successful from both a technical and a clinical point of view. All patients except one were mobilized on the first day after operation and received a normal diet. A thorough preoperative evaluation of the patient with regard to selection of the right size of the implant is necessary, and the implantation must be performed with great attention to technical details.

    Despite rapid advances in interventional imaging, the navigation of a guide wire through abdominal vasculature remains, not only for novice radiologists, a difficult task. Since this navigation is mostly based on 2D fluoroscopic image sequences from one view, the process is slowed down significantly due to missing depth information and patient motion. We propose a novel approach for 3D dynamic roadmapping in deformable regions by predicting the location of the guide wire tip in a 3D vessel model from the tip's 2D location, respiratory motion analysis, and view geometry. In a first step, the method compensates for the apparent respiratory motion in 2D space before backprojecting the 2D guide wire tip into three dimensional space, using a given projection matrix. To countervail the error connected to the projection parameters and the motion compensation, as well as the ambiguity caused by vessel deformation, we establish a statistical framework, which computes a reliable estimate of the guide wire tip location within the 3D vessel model. With this 2D-to-3D transfer, the navigation can be performed from arbitrary viewing angles, disconnected from the static perspective view of the fluoroscopic sequence. Tests on a realistic breathing phantom and on synthetic data with a known ground truth clearly reveal the superiority of our approach compared to naive methods for 3D roadmapping. The concepts and information presented in this paper are based on research and are not commercially available. PMID:18982662

    A study of 12 patients with giant horseshoe abscess of the abdominal and pelvic cavities seen at the Surgical Services of the University of Cincinnati Medical Center has emphasized the complexity and bizarre nature of these lesions. These infections represented a huge abscess or series of communicating abscesses extending from one subphrenic space along the corresponding paracolic gutter into the pelvis, up and along the opposite paracolic space, and into the other subphrenic space. Since these lesions occurred infrequently, they were often not recognized until they had become far advanced and had produced profound effects on the patients. The diagnosis was difficult and obscured by various factors including the postoperative state after laparotomy for complex diseases or serious injuries of the biliary tract, the genitourinary tract, or the alimentary tract. An important etiologic component of the formation of these giant abscesses was the continuing escape and collection of large volumes of fluid resulting from lesions of the biliary tract, postoperative hemorrhage, or an unrecognized large perforated peptic ulcer. Nine patients were treated successfully and 3 died. The many diagnostic and therapeutic problems presented by the patients with this interesting and complex lesion have emphasized the importance of earlier and more accurate diagnosis, early and adequate surgical drainage, intelligently applied antibiotic therapy and appropriate supportive treatment. Failure to recognize and drain effectively each of the component sections of this lesion led to continuing sepsis with prolonged morbidity, progressive debility, and death. Images Fig. 1. Fig. 2.

    A healthy, 34-year-old, gravida 3, para 1,011, patient presented for cesarean delivery in her 35th week of gestation with a diagnosis of complete placenta previa. During her 26th week of gestation, the patient was admitted to a high-risk obstetric unit with the diagnosis of premature rupture of membranes. Numerous ultrasonographic studies were conducted throughout her 10-week hospital stay, confirming the admitting diagnosis. A routine cesarean section was planned, and preparations were made for a potential increase in blood loss related to the placenta previa. The procedure began under spinal anesthesia and, upon incision of the abdomen, an extrauterine pregnancy was identified. The patient was immediately anesthetized and intubated at the request of the surgeon. During the 3-hour surgical procedure, the patient sustained massive blood loss, transfusions, central line placement, and aggressive pharmacological therapy. The patient was extubated the day after surgery, and was discharged approximately 1 week later. The only major complication was compartment syndrome of the left upper extremity related to the infiltration of vasopressors requiring fasciotomy and closure 2 days later. The incidence, morbidity/mortality, and anesthetic implications of abdominal pregnancy are reviewed.

    A completely percutaneous approach to infrarenal abdominal aortic aneurysm (AAA) endografting has the theoretic benefits of being minimally invasive and more expedient. Our goal was to demonstrate the utility of this approach using a suprarenal fixation device and a suture-mediated closure system. We conducted a single-institution, retrospective review of 14 patients who underwent percutaneous AAA repair with the Zenith device between August 2003 and March 2007. Immediate and delayed access-related outcomes were examined over a mean follow-up of 12.1+/-2.0 months. Mean AAA size was 5.6 cm. Immediate arterial closure and technical success rate was 96% (27/28 vessels). One immediate hemostatic failure required open surgical repair. Over follow-up, one vessel required operative repair for new-onset claudication. No other immediate or delayed complications (thrombosis, pseudoaneurysm, infection, or deep venous thrombosis) were detected. A percutaneous approach for the treatment of AAA has several advantages over femoral artery cutdown but also has its own unique set of risks in the immediate and late postoperative period. Ultimately, the "preclose technique" can be safely applied for the Zenith device despite its large-bore delivery system.

    Abdominal aortic aneurysms (AAAs), which commonly occur among elderly individuals, are accompanied by a risk of rupture and subsequent high mortality. Establishment of medical therapies for the prevention of AAAs requires further understanding of the molecular pathogenesis of this condition. This report details the possible involvement of Osteoprotegerin (OPG) in the prevention of AAAs through inhibition of Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL). In CaCl2-induced AAA models, both internal and external diameters were significantly increased with destruction of elastic fibers in the media in Opg knockout (KO) mice, as compared to wild-type mice. Moreover, up-regulation of TRAIL expression was observed in the media by immunohistochemical analyses. Using a culture system, both the TRAIL-induced expression of matrix metalloproteinase-9 in smooth muscle cells (SMCs) and the chemoattractive effect of TRAIL on SMCs were inhibited by OPG. These data suggest that Opg may play a preventive role in the development of AAA through its antagonistic effect on Trail. PMID:26783750

    Background/Aim: Intestinal tuberculosis needs to be considered in the differential diagnosis when patients with intestinal pathology are encountered. Tuberculosis can mimic other disease entities like, ischemic enteritis, inflammatory bowel diseases, malignancies, intussusception etc., clinically as well as morphologically in resected intestinal specimens. We aimed to study the various clinical presentations leading to intestinal resection, with identification of different etiological factors by histopathological examination; and to illustrate, discuss and describe the various histopathological features of the lesions in these resected intestinal specimens with clinicopathological correlation. Materials and Methods: We studied 100 cases of resected intestinal specimens received during September 2002 to December 2003. We totally encountered 22 request forms with clinical suspicion of ileoceocal tuberculosis. Results: Abdominal tenderness and mass in ileoceocal region were noted in all cases. In many instances, the cases were operated for acute/subacute intestinal obstruction. Clinical and intra-operative diagnoses of tubercular enteritis, in many instances, were finally diagnosed histopathologically as ischemic enteritis (nine cases), chronic nonspecific enteritis (four cases), adenocarcinoma of the caecum, Crohn’s disease, intussusception (each one case), and correctly as intestinal tuberculosis in only six cases. Conclusion: Tuberculosis can mimic various disease entities, clinically and sometimes morphologically. Vice versa is also true. An increased awareness of intestinal tuberculosis coupled with varied clinical presentations, nonspecific signs and symptoms, difficulties in diagnostic methods and need of early and specific treatment should improve the outcome for patients with this disease.

    We discuss the results of combined in-vitro laboratory measurements and clinical observations aimed at determining the effect that the unsteady wall shear stresses and the pressure may have on the growth and eventual rupturing of an Abdominal Aortic Aneurysm (AAA), a permanent bulging-like dilatation occurring near the aortic bifurcation. In recent years, new non-invasive techniques, such as stenting, have been used to treat these AAAs. However, the development of these implants, aimed at stopping the growth of the aneurysm, has been hampered by the lack of understanding of the effect that the hemodynamic forces have on the growth mechanism. Since current in-vivo measuring techniques lack the precision and the necessary resolution, we have performed measurements of the pressure and shear stresses in laboratory models. The models of the AAA were obtained from high resolution three-dimensional CAT/SCANS performed in patients at early stages of the disease. Preliminary DPIV measurements show that the pulsatile blood flow discharging into the cavity of the aneurysm leads to large spikes of pressure and wall shear stresses near and around its distal end, indicating a possible correlation between the regions of high wall shear stresses and the observed location of the growth of the aneurysm.

    Patients with abdominal aortic aneurysms (AAAs) are usually treated with endovascular aneurysm repair (EVAR), which has become the standard of care in many hospitals for patients with suitable anatomy. Clinical evidence indicates that EVAR is associated with superior perioperative outcomes and similar long-term survival compared with open repair. Since the randomized, controlled trials that provided this evidence were conducted, however, the stent graft technology for infrarenal AAA has been further developed. Improvements include profile downsizing, optimization of sealing and fixation, and the use of low porosity fabrics. In addition, imaging techniques have improved, enabling better preoperative planning, stent graft placement, and postoperative surveillance. Also in the past few years, fenestrated and branched stent grafts have increasingly been used to manage anatomically challenging aneurysms, and experiments with off-label use of stent grafts have been performed to treat patients deemed unfit or unsuitable for other treatment strategies. Overall, the indications for endovascular management of AAA are expanding to include increasingly complex and anatomically challenging aneurysms. Ongoing studies and optimization of imaging, in addition to technological refinement of stent grafts, will hopefully continue to broaden the utilization of EVAR. PMID:24343568

    Dextromethorphan is an N-methyl-D-aspartate (NMDA) receptor antagonist which has been shown to inhibit the development of cutaneous secondary hyperalgesia after tissue trauma. We studied 60 ASA I-II patients undergoing total abdominal hysterectomy in a randomized, double-blind, placebo-controlled study. Patients received either dextromethorphan 27 mg capsules, two doses before operation and three doses in the first 24 h after operation, or placebo. Visual analogue pain scores (VAS) at 24 and 48 h were assessed at rest, on coughing and on sitting up, and were not significantly different between groups. Morphine consumption from a patient-controlled analgesia (PCA) device was also not significantly different between groups. Evidence of secondary hyperalgesia was assessed with von Frey hairs 10 cm above the Pfannenstiel incision. Both groups of patients exhibited evidence of secondary hyperalgesia after 24 and 48 h but there were no significant differences between groups. There was also no difference between groups in VAS scores at 1 month.

    Despite of significant development of modern surgery results of treatment of acute diffused peritonitis and acute intestinal obstruction are still unsatisfactory. Successful treatment of these conditions depends considerably on timely and adequate diagnosing as it gives a choice of optimal treatment tactics. Measuring of a human body heat flow in areas of organs affected by pathology in cases of acute diffused peritonitis and acute intestinal obstruction provides a possibility to improve the principles of early differential diagnosing, to form new approaches to treatment tactics and monitoring of general health status of a patient during early postoperative treatment. 47 patient suffering from acute diffused peritonitis and 42 patients suffering from acute intestinal obstruction have been examined; the patients were divided into groups based on abdominal cavity exudates character, intestinal obstruction type and intra-abdominal hypertension grade. Measurement of abdominal cavity heat flow was performed by a contact method with use of thermoelectric medical thermometer. Intra-abdominal hypertension was measured by generally used transvesical method. It has been established that abdominal cavity heat flow correlates with character of abdominal cavity exudates; this is also confirmed by reliable difference between serous peritonitis and fibrinopurulent peritonitis indices. Indices in case of acute intestinal obstruction are lower than ones in case of acute diffused peritonitis as there are no inflammatory changes of peritoneum. Development of intra-abdominal hypertension of grades 3-4 directly influences the heat flow extent; this is explained by accelerated and aggravated pathological changes of inner organs cased by the main disease. Thus, abdominal cavity heat flow fully reflects degree of purulent and inflammatory processes of abdominal cavity organs and can be used for additional diagnosing and clinical course monitoring.

    Objectives: To investigate the effect of non-elastic/elastic abdominal binders on intra-vesical pressure (IVP), physiological functions, and clinical outcomes in laparotomy patients at the perioperative stage. Methods: This prospective study was conducted from May to October 2014 at the Trauma Surgery Department, Daping Hospital, Chongqing, China. Laparotomy patients were randomly divided into non-elastic abdominal binder group (28 patients), and elastic abdominal binder group (29 patients). Binders were applied for 14 days following the operation, or until discharge. Demographic information, Sequential Organ Failure Assessment (SOFA) and Acute Physiology and Chronic Health Evaluation II (APACHE-II) scores (prior to the operation, on the first day after operation, the day IVP measurement was stopped, and one day before discharge), and outcomes were recorded. The IVP was measured before the operation to postoperative day 7. Results: There were no significant differences in the demographic information, outcomes, SOFA or APACHE-II scores between the 2 groups. Initial out-of-bed mobilization occurred earlier in the elastic binder group (3.2 ± 2.0 versus 5.0 ± 3.7 days, p=0.028). A greater increase in IVP was observed in the non-elastic binder group than in the elastic binder group (2.9 ± 1.1 versus 1.1 ± 0.7 mm Hg, p=0.000). Conclusion: Elastic binders have relatively little effect on IVP and are more helpful at promoting postoperative recovery than non-elastic binders. Therefore, elastic binders are more suitable for clinical use. PMID:26739977

    It is reported of an abdominal pregnancy at term. The placenta was left in situ because of the high risk of intraabdominal bleedings. Thereby it was possible to measure hormon concentrations of the fetoplacental unit without the fetal compartment. Within 10 days after delivery we determined the plasma levels of estradiol-17 beta, estriol, progesterone, HCS, alpha1fetoprotein, and the excretion of the total estrogens in the urines. There was near the same decrease of hormon concentrations in the post partal time comparable with that of a normal pregnancy. Only the HCS concentrations didn't change in the first 9 days after delivery.

    The management of abdominal wall repair continues to present a challenging problem, especially in the repair of major defects. Many abdominal wall defects can be repaired by primary closure; however, if the defect is large and there is a tension on the closure of the wound, the use of prosthetic materials becomes indispensable. Many studies have been performed with various materials and implant techniques, without the comparison of their degrees of success, based on sound meta-analysis and/or inclusive epidemiologic studies. This review covered the effectiveness of recent advances in prosthetic materials and implant procedures used in repair of abdominal wall, based on biomechanical properties and economic aspects of reconstructed large abdominal wall defects and hernias in animals. The presented results in this review helped to reach treatment algorithms that could maximize outcomes and minimize morbidity. PMID:27293982

    Traumatic abdominal wall hernia (TAWH) is a rare clinical entity in terms of aetiology. It occurs following a blunt abdominal injury with energy high enough to cause disruption of the musculoaponeurotic layer but not the elastic skin layer. It is often associated with underlying intra-abdominal injuries, which can be diagnosed either clinically or radiologically. We report a case of TAWH in a young man with associated large bowel transection, which remained undiagnosed in the preoperative period owing to its masked features. He was managed surgically, with no recurrence to date. Considering the high volume of blunt abdominal trauma cases that present to the accident and emergency department, only few cases of TAWH have been reported in the literature. Confusion still exists regarding the timing and mode of management of this condition. PMID:27241601

    Surgeons occasionally encounter a patient with a gastric cancer invading an adjacent organ, such as the pancreas, liver, or transverse colon. Although there is no established guideline for treatment of invasive gastric cancer, combined resection with radical gastrectomy is conventionally performed for curative purposes. We recently treated a patient with a large gastric cancer invading the abdominal wall, which was initially diagnosed as a simple abdominal wall abscess. Computed tomography showed that an abscess had formed adjacent to the greater curvature of the stomach. During surgery, we made an incision on the abdominal wall to drain the abscess, and performed curative total gastrectomy with partial excision of the involved abdominal wall. The patient received intensive treatment and wound management postoperatively with no surgery-related adverse events. However, the patient could not receive adjuvant chemotherapy and expired on the 82nd postoperative day. PMID:26468420

  17. The potential participation of abdominal pressure in preeclampsia.

    Preeclampsia is a major cause of maternal and perinatal mortality and morbidity. Regardless of susceptibility or predisposing conditions and risk factors, the degree of increase in abdominal pressure is directly related to the severity of preeclampsia, particularly in women with hydatidiform mole. When increased abdominal pressure is normalized by delivery, preeclampsia is cured. Recent genetic studies highlighted two leading risk factors for preeclampsia: chronic renal disease and T235 homozygosity for the AGT gene. Thus, while there is increased abdominal pressure in pregnancy, an imbalanced renin angiotensin system and renal injuries lead to a vicious cycle of increasing abdominal pressure and further renal injuries. A hypothesis for the potential participation of pressure in preeclampsia is described and the amelioration of preeclampsia through postural intervention and the possible therapeutic effect of angiotensin is suggested.

    Abstract Follicular dendritic cell sarcoma (FDCS) is a neoplasm that arises from follicular dendritic cells. FDCSs originating in the abdomen are extremely rare. Clinically, they often mimic a wide variety of other abdominal tumors, and correct preoperative diagnosis is often a challenging task. To date, only scattered cases of abdominal FDCS have been reported and few data are available on their radiological features. Here we present the computer tomography imaging findings of 5 patients with surgically and pathologically demonstrated abdominal FDCS. An abdominal FDCS should be included in the differential diagnosis when single or multiple masses with relatively large size, well- or ill-defined borders, complex internal architecture with marked internal necrosis and/or focal calcification, and heterogeneous enhancement with “rapid wash-in and slow wash-out” or “progressive enhancement” enhancement patterns in the solid component are seen.

    Previous studies have demonstrated that booster seats reduce the risk of abdominal injuries by improving the fit of the seat belt on young children and encouraging better posture and compatibility with the vehicle seat. Recently, several studies have reported cases of abdominal injuries in booster seated children questioning the protective effects of these restraints. The objective of this study was to examine cases of abdominal injuries in booster seated children through parametric modeling to gain a thorough understanding of the injury causation scenarios. The Partners for Child Passenger Safety and CIREN in-depth crash investigation databases were queried to identify children in belt-positioning booster seats with abdominal injuries. The injury causation scenarios for these injuries were delineated using the CIREN Biotab method. The cases were modeled, using MADYMO with variations in key parameters, to determine the ranges of loads and loading rates for the abdomen and thorax. A parametric study was completed examining the influence of pretensioners and load limiters on the injury metrics obtained. Query of the two databases revealed three cases involving abdominal injuries to booster seated children. Children in two of the cases sustained a thoracic injury (AIS 3/AIS 4) in addition to their abdominal injuries (AIS 2) and review of these cases pointed to the role of shoulder belt loading in the injury causation. Modeling of these cases revealed chest compressions and accelerations of 30–53 mm and 41–89 g, respectively and abdominal deflection and velocity of 7.0–13.3 mm and 1.2–2.2 m/s, respectively. Parametric study suggested that coupling shoulder belt load limiting and lap belt buckle pretensioning resulted in improved chest and abdominal metrics while reducing head excursion, indicating that these technologies may provide injury reduction potential to pediatric rear seat occupants.

    In the pediatric population, abdominal compartment syndrome (ACS) is a known complication of abdominal wall defect repair. However, there are only few reports on ACS in newborns and only a proposal of critical intra-abdominal pressure value (IAP) in term newborns, absent in preterm newborns. Although the prevalent clinical sign is tense abdominal distension, it may be difficult to distinguish ACS from pathologies that will not require decompression. The purpose of this study was to identify predictors for ACS and therefore morbidity or mortality indicators. We reviewed newborns presenting with tense abdominal distension and end organ failure. Anamnestic, clinical, laboratory, and instrumental investigations were analyzed to extrapolate predictors. Outcomes were compared with a control group. The incidence of ACS in our neonatal intensive care unit was 5% in the overall population of babies, 16% in tracheal-ventilated newborns, and 57% in infants with abdominal wall defects. We found that, with onset of acidosis or high gastric residuals, the lactate values will be predictive for mortality. We can also suggest paying particular attention to high lactate values just at the onset of distension, in infants with more advanced gestational age, with previously surgical repair, to determine early surgical intervention independently of a specific IAP measurement.

    Although abdominal pain is a symptom of several structural gastrointestinal disorders (eg, peptic ulcer disease), this comprehensive review will focus on the 4 most common nonstructural, or functional, disorders associated with abdominal pain: functional dyspepsia, constipation-predominant and diarrhea-predominant irritable bowel syndrome, and functional abdominal pain syndrome. Together, these conditions affect approximately 1 in 4 people in the United States. They are associated with comorbid conditions (eg, fibromyalgia and depression), impaired quality of life, and increased health care utilization. Symptoms are explained by disordered gastrointestinal motility and sensation, which are implicated in various peripheral (eg, postinfectious inflammation and luminal irritants) and/or central (eg, stress and anxiety) factors. These disorders are defined and can generally be diagnosed by symptoms alone. Often prompted by alarm features, selected testing is useful to exclude structural disease. Identifying the specific diagnosis (eg, differentiating between functional abdominal pain and irritable bowel syndrome) and establishing an effective patient-physician relationship are the cornerstones of therapy. Many patients with mild symptoms can be effectively managed with limited tests, sensible dietary modifications, and over-the-counter medications tailored to symptoms. If these measures are not sufficient, pharmacotherapy should be considered for bowel symptoms (constipation or diarrhea) and/or abdominal pain; opioids should not be used. Behavioral and psychological approaches (eg, cognitive behavioral therapy) can be helpful, particularly in patients with chronic abdominal pain who require a multidisciplinary pain management program without opioids.

    As hernias and abdominal wall defects have a variety of etiologies each with its own complications and comorbidities in various constellations, efficient treatment requires patient-oriented management. There is no recommended standard treatment and the very different clinical pictures demand an individualized interdisciplinary approach. Particularly in the case of complicated hernias, the planning of the operation should focus on the problems posed by the individual patient. Treatment mainly depends on the etiology of the hernia, immediate or long-term complications and the efficiency of individual repair techniques. Abdominal wall repair for recurrent herniation requires direct closure of the fascia generally using the sublay technique with a lightweight mesh. It is still unclear whether persistent inflammation, mesh dislocation, fistula formation or other long-term complications are due to certain materials or to the surgical technique. With mesh infections it has been shown to be advantageous to remove a polytetrafluoroethylene (PTFE) mesh, while the combination of systemic and local treatment appears to suffice for a polypropylene or polyester mesh. Heavier meshes in the sublay position or plastic reconstruction with autologous tissue are indicated as substitutes for the abdominal wall for giant hernias, repeated recurrences and large abdominal wall defects. A laparostoma is increasingly more often created to treat septic intra-abdominal processes but is very often responsible for a complicated hernia. If primary repair of the abdominal wall is not an option, resorbable material or split skin is used for coverage under the auspices of a planned hernia repair.

    Intra-abdominal adhesions constitute a significant clinical and surgical problem that can lead to complications such as pain and bowel occlusion or subocclusion. These adhesions are frustrating and potentially fatal, representing a major postoperative complication in abdominal surgery. It is estimated that 32% of horses undergoing laparotomy will present clinical symptoms due to adhesions, but the true prevalence is not known because a large proportion of animals with postoperative recurrent colics are medically treated or submitted to euthanasia without necropsy. Adhesions are highly cellular, vascularized, dynamic structures that are influenced by complex signaling mechanisms. Understanding their pathogenesis could assist in applying better therapeutic strategies and in developing more effective antiadhesion products. Currently, there are no definitive strategies that prevent adhesion formation, and it is difficult to interpret the results of existing studies due to nonstandardization of an induction model and evaluation of their severity. The best clinical results have been obtained from using minimally traumatic surgical techniques, anti-inflammatory agents, antimicrobials, anticoagulants, and mechanical separation of serosal surfaces by viscous intraperitoneal solutions or physical barriers. This paper aims to review adhesion formation pathogenesis, guide the understanding of major products and drugs used to inhibit adhesion formation, and address their effectiveness in the equine species.

    [Purpose] This study was intended to examine the most effective feedback method for contracting the musculus transversus abdominis muscle by using basic training, a pressure biofeedback unit, and real-time ultrasonographic imaging during abdominal hollowing exercise training. [Subjects and Methods] The subjects in this study were 30 healthy young students in their twenties. Thirty subjects were divided randomly and equally into the basic training, the pressure biofeedback unit, and real-time ultrasonographic imaging groups. All of the subjects received abdominal hollowing exercise training for 15 minutes. The subjects in the pressure biofeedback unit group were trained by using a pressure biofeedback unit. Those in the real-time ultrasonographic imaging group received training with monitoring of possible contraction of their musculus transversus abdominis muscles on ultrasonography. [Results] In all the three groups, the musculus transversus abdominis became significantly thicker, but more significantly in the real-time ultrasonographic imaging group than in the basic training group. [Conclusion] The feedback method using real-time ultrasonographic imaging may be more effective in thickening the musculus transversus abdominis muscle during exercise than the traditional feedback method with manual contact only. However, it is insufficient in terms of overall qualitative improvement of exercise outcome. PMID:27799683

    Background In the context of increasing obesity prevalence, the relationship between large visceral adipose tissue (VAT) volumes and type 2 diabetes mellitus (T2DM) is unclear. In a clinical sample of severely obese women (mean body mass index [BMI], 46 kg/m2) with fasting normoglycemia (n=40) or dysglycemia (impaired fasting glucose+diabetes; n=20), we sought to determine the usefulness of anthropometric correlates of VAT and associations with dysglycemia. Methods VAT volume was estimated using multi-slice computer tomography; anthropometric surrogates included sagittal abdominal diameter (SAD), waist circumference (WC) and BMI. Insulin sensitivity (Si), and beta-cell dysfunction, measured by insulin secretion (AIRg) and the disposition index (DI), were determined by frequently sampled intravenous glucose tolerance test. Results Compared to fasting normoglycemic women, individuals with dysglycemia had greater VAT (P<0.001) and SAD (P=0.04), but BMI, total adiposity and Si were similar. VAT was inversely associated with AIRg and DI after controlling for ancestry, Si, and total adiposity (standardized beta, −0.32 and −0.34, both P<0.05). In addition, SAD (beta=0.41, P=0.02) was found to be a better estimate of VAT volume than WC (beta=0.32, P=0.08) after controlling for covariates. Receiver operating characteristic analysis showed that VAT volume, followed by SAD, outperformed WC and BMI in identifying dysglycemic participants. Conclusions Increasing VAT is associated with beta-cell dysfunction and dysglycemia in very obese women. In the presence of severe obesity, SAD is a simple surrogate of VAT, and an indicator of glucose dysregulation. PMID:23408092

    Objective Currently, the association between abdominal aortic plaques and coronary artery disease (CAD) has not yet been clarified clearly. The purpose of this study was to determine the prevalence of abdominal aortic plaques by ultrasound imaging and to explore its association with CAD in patients undergoing coronary angiography. Methods Between October 2014 and June 2015, a prospective study was conducted in the Department of Cardiology at Guangdong General Hospital, Guangzhou, People’s Republic of China. Ultrasound scanning of the abdominal aortas was performed in 1,667 consecutive patients undergoing coronary angiography. Clinical characteristics and coronary profile were collected from the patients. Results Of the 1,667 study patients (male, 68.9%; mean age, 63±11 years) undergoing coronary angiography, 1,268 had CAD. Compared with 399 patients without CAD, 1,268 patients with CAD had higher prevalence of abdominal aortic plaques (37.3% vs 17%, P<0.001). In multivariate analysis, abdominal aortic plaques served as independent factors associated with the presence of CAD (odds ratio =2.08; 95% confidence interval =1.50–2.90; P<0.001). Of the 1,268 patients with CAD, the prevalence of abdominal aortic plaques was 27.0% (98/363) in patients with one-vessel disease, 35.0% (107/306) in patients with two-vessel disease, and 44.7% (268/599) in patients with three-vessel disease. Stepwise increases in the prevalence of abdominal aortic plaque was found depending on the number of stenotic coronary vessels (P<0.001; P-value for trend <0.001). In an ordinal logistic regression model, abdominal aortic plaques served as independent factors associated with the severity of CAD according to the number of stenotic coronary vessels (P<0.001). Conclusion The prevalence of abdominal aortic plaques was higher in patients with CAD than in those without CAD. Abdominal aortic plaque was an independent factor associated with the presence and severity of CAD. PMID:27279740

    1. Single-nerve fibre action potentials (APs) were recorded with 2 pairs of wire electrodes from lower sacral nerve roots during surgery in patients with spinal cord injury and in a brain-dead human. Conduction velocity distribution histograms were constructed for afferent and efferent fibres, nerve fibre groups were identified and simultaneous impulse patterns of alpha and gamma-motoneurons and secondary muscle spindle afferents (SP2) were constructed. Temporal relations between afferent and efferent APs were analyzed by interspike interval (II) and phase relation changes to explore the coordinated self-organization of somatic and parasympathetic neuronal networks in the sacral micturition centre during continence functions under physiologic (brain-dead) and pathophysiologic conditions (spinal cord injury). 2. In a paraplegic with hyperreflexia of the bladder, urinary bladder stretch (S1) and tension receptor afferents (ST) fired already when the bladder was empty, and showed a several times higher bladder afferent activity increase upon retrograde bladder filling than observed in the brain-dead individual. Two alpha2-motoneurons (FR) innervating the external bladder sphincter were already oscillatory firing to generate high activity levels when the bladder was empty. They showed activity levels with no bladder filling, comparable to those measured at a bladder filling of 600 ml in the brain-dead individual. A bladder storage volume of 600 ml was thus lost in the paraplegic, due to a too high bladder afferent input to the sacral micturition center, secondary to inflammation and hypertrophy of the detrusor. 3. In a brain-dead human, 2 phase relations existed per oscillation period of 160 ms between the APs of a sphincteric oscillatory firing alpha2-motoneuron, a dynamic fusimotor and a secondary muscle spindle afferent fibre. Following stimulation of mainly somatic afferent fibres, the phase relations changed only little. 4. In a paraplegic with dyssynergia of the

    Purpose: This retrospective analysis describes our 35-year experience with respect to disease control and functional status. Patients and Methods: Thirty-five patients with localized Ewing tumors of the pelvis and sacral bones were treated from 1970 to 2005. Twenty-six patients were treated with definitive radiotherapy (RT), and 9 patients were treated with combined local therapy in the form of surgery + RT. The median RT dose was 55.2 Gy. The patients who received RT alone were more likely to be older men with larger tumors exhibiting soft-tissue extension. Patients in the definitive RT group were more likely to receive etoposide and ifosfamide or undergo bone marrow transplant. Median potential follow-up was 19.4 years. Results: The 15-year actuarial cause-specific survival, freedom from relapse rate, and local control rates were 26% vs. 76% (p = 0.016), 28% vs. 78% (p = 0.015), and 64% vs. 100% (p = 0.087), respectively, for patients treated with definitive RT and combined therapy. Overall, tumors <8 cm had significantly better cause-specific survival, but this was unrelated to local control. The median Toronto Extremity Salvage Score for the definitive RT and combined therapy groups were 99 and 94, respectively (p = 0.19). Seven definitive RT patients (27%) had serious complications. Conclusion: Combined modality local therapy should be considered if pelvic Ewing tumors are resectable. However, because of the extent of local disease, most patients have unresectable or partially resectable tumors and therefore require RT in some capacity. For this reason, innovative RT strategies are needed to improve long-term disease outcomes and minimize side effects while maintaining an acceptable functional result.

    A rigid spino-pelvic fixation to anchor long constructs is crucial to maintain the stability of long fusion in spinal deformity surgery. Besides obtaining immediate stability and proper biomechanical strength of constructs, the S2 alar-iliac (S2AI) screws have some more advantages. Four Korean fresh-frozen human cadavers were procured. Free hand S2AI screw placement is performed using anatomic landmarks. The starting point of the S2AI screw is located at the midpoint between the S1 and S2 foramen and 2 mm medial to the lateral sacral crest. Gearshift was advanced from the desired starting point toward the sacro-iliac joint directing approximately 20° angulation caudally in sagittal plane and 30° angulation horizontally in the coronal plane connecting the posterior superior iliac spine (PSIS). We made a S2AI screw trajectory through the cancellous channel using the gearshift. We measured caudal angle in the sagittal plane and horizontal angle in the coronal plane. A total of eight S2AI screws were inserted in four cadavers. All screws inserted into the iliac crest were evaluated by C-arm and naked eye examination by two spine surgeons. Among 8 S2AI screws, all screws were accurately placed (100%). The average caudal angle in the sagittal plane was 17.3±5.4°. The average horizontal angle in the coronal plane connecting the PSIS was 32.0±1.8°. The placement of S2AI screws using the free hand technique without any radiographic guidance appears to an acceptable method of insertion without more radiation or time consuming. PMID:26819698

    Purpose The aim of this study was to develop a controlled approach for sacral neuromodulation (SNM) to improve both nerve targeting and tined lead placement, for which a new computed tomography (CT)-guided implantation technique was analyzed in minipigs. Materials and methods This study included five female, adult Göttingen minipigs. In deep sedoanalgesia, the minipigs were placed in an extended prone position. Commercially available SNM materials were used (needle, introduction sheath, and quadripolar tined lead electrode). Gross anatomy was displayed by CT, and the nerves were bilaterally identified. The optimal angles to puncture the S3 foramen, the resulting access path, and the site for the skin incision were defined subsequently. The needle puncture and the tined lead placement were followed by successive CT scans/3D-reconstruction images. Once proper CT-guided placement of the needle and electrode was established, response to functional stimuli was intraoperatively checked to verify correct positioning. Results Successful bilateral tined lead implantation was performed in four out of five minipigs. Implantation was different from the clinical situation because the puncture was done from the contralateral side at a 30° angle to the midline and 60° horizontal angle to ensure both passage through the foramen and nerve access. Surgery time was 50–150 minutes. Stimulation response comprised a twitch of the perianal musculature and tail rotation to the contralateral side. Conclusion We have established a new, minimally invasive, highly standardized, CT-guided SNM electrode implantation technique. Functional outcomes are clearly defined and reproducible. All procedures can be performed without complications. Future chronic stimulation studies in minipigs can thereby be conducted using a controlled and highly standardized protocol. PMID:27730097

    Introduction The repair of large incisional hernias may occasionally lead to a substantial increase in intra-abdominal pressure (IAP), and rarely to abdominal compartmental syndrome (ACS) with subsequent respiratory, vascular, and visceral complications. Measurement of the IAP has recently become a common practice in monitoring critical patients, even though such measurements were obtained in the early 1900s. Patients and Methods A prospective study involving 54 patients undergoing elective abdominal wall gap repair (mean length, 17.4 cm) with a tension-free technique after incisional hernia was conducted. The purpose of the study was to determine whether or not urinary pressure for indirect IAP measurement is a reliable method for the early identification of patients with a higher risk of developing ACS. IAP measurements were performed using a Foley catheter connected to a HOLTECH® medical manometer. IAP values were determined pre-operatively, after anesthetic induction, upon patient awakening, upon patient arrival in the ward after surgery, and 24 h after surgery before removing the catheter. All patients were treated by the same surgical team using a prosthetic composite mesh (PARIETEX®). Results Incisional hernia repair caused an increase in the mean IAP score of 2.68 mmHg in 47 of 54 patients (87.04%); the IAP was decreased in two patients (3.7%) and remained equal in five patients before and 24 h after surgery (9.26%). FEV-1, measured 24 h after surgery, increased in 50 patients (92.6%), remained stable in two patients (3.7%), and decreased in two patients (3.7%). The mean increase in FEV-1 was 0.0676 L (maximum increase = 0.42 L and minimum increase = 0.01 L) in any patient who developed ACS. Conclusions Measurement of urinary bladder pressure has been shown to be easy to perform and free of complications. Measurement of urinary bladder pressure can also be a useful tool to identify patients with a higher risk of developing ACS. PMID:27142823

    The purpose of this study was to examine visceral fat mass as well as other measures abdominal body composition in National Football League (NFL) players before the start of the season. Three hundred and seventy NFL football players were measured before the start of the season using dual-energy x-ray absorptiometry. Regional fat and lean mass was measured for each player. Players were categorized into 3 groups based on positions that mirror each other: linemen; linebackers/tight ends/running backs and wide receivers/defensive backs. Significant differences were observed between the position groups for both lean and fat regional measurements. However, the magnitude of difference was much greater for fat measures than lean measures. Additionally, a threshold was observed (∼114 kg) at which there is a greater increase in fat accumulation than lean mass accumulation. The increase in fat accumulation is distributed to the abdominal region where thresholds were observed for subcutaneous abdominal fat accumulation (12.1% body fat) and visceral abdominal fat accumulation (20.1% body fat), which likely explains the regional fat differences between groups. The results of this study suggest that as players get larger, there is more total fat than total lean mass accumulation and more fat is distributed to the abdominal region. This is of importance as increased fat mass may be detrimental to performance at certain positions. The thresholds observed for increased abdominal fat accumulation should be monitored closely given recent research observed that abdominal obesity predicts lower extremity injury risk and visceral adipose tissue's established association with cardiometabolic risk.

  1. Obstetrical catastrophe averted: successful outcome of an abdominal pregnancy.

    Abdominal pregnancy is defined as an implantation in peritoneal cavity, exclusive of tubal, ovarian, or intraligmentary pregnancy.These pregnancies are rarely encountered and can go undiagnosed until advanced period of gestation [1]. Frequency of abdominal pregnancy has been directly related to the frequency of ectopic gestation as constituting 2% of ectopics and nearly 0.01% of all pregnancies [2-4]. These pregnancies are seen more commonly in developing countries and poses special challenges to the clinician. Advanced abdominal pregnancy is life-threatening condition and carries high risk of hemorrhage, disseminated intravascular coagulation, bowel injury, and fistulae [5]. The perinatal outcome is mainly influenced by the availability of blood supply and site of implantation [6]. Most of the fetus die in utero because of compromised environment, and those who survive face problems due to congenital malformations [3,7]. Patients of abdominal pregnancy can have variable clinical presentation, and physical examination may be inconclusive for making diagnosis [7,8]. Clinical features like irregular bleeding per vaginum, abdominal pain, dyspepsia, altered bowel habits, malpresentation, and extremely anteriorly placed cervix should raise the suspicion [2,3,8,9]. Diagnostic challenge with oxytocin stimulation, abdominal x-ray, hysterosalpingography, and ultrasonography has been used as tools to assist in diagnosis [10,11]. Magnetic resonance imaging is found to complement sonography in making accurate diagnosis and can be useful to demonstrate the relationship between fetus, the cervix, and the myometrium [12]. We hereby report a successful operative delivery of a live baby after a term extrauterine abdominal pregnancy in a multigravida in whom the diagnosis was made after laparotomy.

    In the future, medical management may play an increasingly important role in the prevention and management of intra-abdominal hypertension (IAH). A review of different databases was used (PubMed, MEDLINE and EMBASE) with the search terms 'Intra-abdominal Pressure' (IAP), 'IAH', ' Abdominal Compartment Syndrome' (ACS), 'medical management' and 'non-surgical management'. We also reviewed all papers with the search terms 'IAH', 'IAP' and 'ACS' over the last three years, only extracting those papers which showed a novel approach in the non-surgical management of IAH and ACS.IAH and ACS are associated with increased morbidity and mortality. Non-surgical management is an important treatment option in critically ill patients with raised IAP. There are five medical treatment options to be considered to reduce IAP: 1) improvement of abdominal wall compliance; 2) evacuation of intra-luminal contents; 3) evacuation of abdominal fluid collections; 4) optimisation of fluid administration; and 5) optimisation of systemic and regional perfusion. This paper will review the first three treatment arms of the WSACS algorithm: abdominal wall compliance; evacuation of intra-luminal contents and evacuation of abdominal fluid collections. Emerging medical treatments will be analysed and finally some alternative specific treatments will be assessed. Other treatment options with regard to optimising fluid administration and systemic and regional perfusion will be described elsewhere, and are beyond the scope of this review. Medical management of critically ill patients with raised IAP should be instigated early to prevent further organ dysfunction and to avoid progression to ACS. Many treatment options are available and are often part of routine daily management in the ICU (nasogastric, rectal tube, prokinetics, enema, sedation, body position). Some of the newer treatments are very promising options in specific patient populations with raised IAP. Future studies are warranted to confirm

    One proposed advantage of robotic surgery is improved ergonomics and decreased surgeon fatigue. The objective of this study is to quantify and compare the physical activity of surgeons during robotic and abdominal surgery using accelerometers. Eight gynecologic surgeons who perform both abdominal and robotic surgery were the subjects of this study. Each wore an accelerometer on the hip during one procedure performed abdominally and during a similar procedure performed robotically. Activity parameters analyzed were average activity counts (AAC) and percentage of time spent in sedentary, light, moderate, and vigorous activity. The paired t-test was used to evaluate differences between robotic and abdominal procedures. AAC was similar between the robotic and abdominal approaches (mean ± SD: 83.9 ± 50.9 versus 79.1 ± 37.8 counts/min, respectively, P = 0.820). The majority of activity spent in robotic and abdominal surgery was sedentary (79.0% ± 5.9% versus 80.9% ± 8.6%, respectively; P = 0.625) followed by light activity (14.7% ± 3.9% versus 12.8% ± 6.1%, respectively; P = 0.541) and then by moderate activity (6.3% ± 3.4% versus 6.3% ± 2.8%, respectively; P = 0.981). None of the activity for either surgical approach qualified as vigorous. There were no differences in activity parameters by surgical approach. Accelerometer data demonstrate that surgeon activity expenditure is similar in robotic and abdominal surgery. Future studies comparing measures of physical activity and strain between surgical approaches are needed to determine whether the robot's improved ergonomics translates to improved surgeon experience.

    , fetal MR imaging generally should not be performed at 3T because of these artifacts and the increased safety concerns. The same holds true for patients with a large amount of ascites, who also are not well suited for an ultrahigh-field MR examination. Except as noted above, most patients can undergo an abdominal MR imaging study at 3T with a reasonable outcome in terms of image quality. PMID:16530632

    ABSTRACT This study aims to investigate the causes and treatment experience of severe abdominal infection after orthotopic liver transplantation. Clinical data were retrospectively analysed in perioperative severe abdominal infection of 186 orthotopic liver transplantation cases from March 2004 to November 2011. Among the 186 patients, 16 cases had severe abdominal infection: five cases had bile duct anastomotic leakage-inducing massive hydrops and infection under liver interstice, 10 cases had extensive bleeding of surgical wound leading to massive haematocele and infection around the liver, and one case had postoperative lower oesophageal fistula leakage causing massive hydrops and infection under the left diaphragm. After definite diagnosis, 12 cases underwent surgery within three days, with no death. Among the four cases that underwent surgery three days after diagnosis, one case died of multiple-organ failure five days after abdominal cavity exploration, which was performed 21 days after liver transplantation. Severe abdominal infections after liver transplantation were the most common causes of death in perioperative liver transplantation. Comprehensive treatment with efficacious antibiotics, multiple-organ support, controlled surgical removal of the lesion, and adequate drainage establishment was the key to the entire treatment.

    This study objective was to verify the behavior of three portions of the abdominal rectus muscle through a quantitative analysis of the electromyographic signal in different types of abdominal exercises. Ten young male between 16 and 27 years old were studied and they had no previous history of muscle and joint illness. They were well-trained and did seven abdominal exercises chosen considering the types of contraction (isotonic and isometric) as well as the muscle fixation points. The electric activity of the superior, medium (above umbilicus) and inferior (below umbilicus) portions at the left side of the abdominal rectus muscle was taken using Beckman type surface mini-electrodes. The registers were collected from computerized 8-channel Nicholet electromyography equipment, model Viking II. The signals were quantified using the MVA (Maximum Volunteer Activity) software, being considered for analysis the values of RMS (Root Mean Square). The obtained data were submitted to a parametric analysis using the variance analysis (F test) and also the Tukey test, besides a descriptive graphic analysis starting from the average RMS values of each muscle portion. This study results suggest that for the majority of the subjects, the functional activities of the abdominal rectus muscle are performed with electric activity differences among their portions, showing a tendency of producing more electric activity in the superior portion than in the medium and inferior portions. The experiment also demonstrated an absence of a common behavior pattern in the three portions of the ten tested subjects. PMID:9444489

    The purpose of this study was to test the hypothesis that the passive drag acting on a gliding swimmer is reduced if the swimmer adopts an abdominal breathing manoeuvre (expanding the abdominal wall) rather than chest breathing manoeuvre (expanding the rib cage). Eleven male participants participated in this study. A specialised towing machine was used to tow each participant with tension set at various magnitudes and to record time series data of towing velocity. Participants were asked to inhale air by expanding the abdominal wall or the rib cage and to maintain the same body configuration throughout gliding. The steady-state velocity was measured and the coefficient of drag was calculated for each towing trial to compare between the breathing manoeuvres. The results showed that the towing velocity was increased by 0.02 m/s with a towing force of 34.3 N and by 0.06 m/s with a towing force of 98.1 N. The coefficient of drag was reduced by 5% with the abdominal breathing manoeuvre, which was found to be statistically significant (p < 0.05). These results indicate that adopting the abdominal breathing manoeuvre during gliding reduces the passive drag and the hypothesis was supported.

    Current pathophysiological models of congestive heart failure unsatisfactorily explain the detrimental link between congestion and cardiorenal function. Abdominal congestion (i.e., splanchnic venous and interstitial congestion) manifests in a substantial number of patients with advanced congestive heart failure, yet is poorly defined. Compromised capacitance function of the splanchnic vasculature and deficient abdominal lymph flow resulting in interstitial edema might both be implied in the occurrence of increased cardiac filling pressures and renal dysfunction. Indeed, increased intra-abdominal pressure, as an extreme marker of abdominal congestion, is correlated with renal dysfunction in advanced congestive heart failure. Intriguing findings provide preliminary evidence that alterations in the liver and spleen contribute to systemic congestion in heart failure. Finally, gut-derived hormones might influence sodium homeostasis, whereas entrance of bowel toxins into the circulatory system, as a result of impaired intestinal barrier function secondary to congestion, might further depress cardiac as well as renal function. Those toxins are mainly produced by micro-organisms in the gut lumen, with presumably important alterations in advanced heart failure, especially when renal function is depressed. Therefore, in this state-of-the-art review, we explore the crosstalk between the abdomen, heart, and kidneys in congestive heart failure. This might offer new diagnostic opportunities as well as treatment strategies to achieve decongestion in heart failure, especially when abdominal congestion is present. Among those currently under investigation are paracentesis, ultrafiltration, peritoneal dialysis, oral sodium binders, vasodilator therapy, renal sympathetic denervation and agents targeting the gut microbiota.

    Objective The impact of co-morbid conditions on early and late clinical outcomes after endovascular treatment of abdominal aortic aneurysm (AAA) was assessed in concurrent cohorts of patients stratified with respect to risk for intervention. Summary Background Data As a minimally invasive strategy for the treatment of AAA, endovascular repair has been embraced with enthusiasm for all prospective patients who are suitable anatomical candidates because of the promise of achieving a durable result with a reduced risk of perioperative morbidity and mortality. Methods From April 1994 to March 2001, endovascular AAA repair was performed in 236 patients using commercially available systems. A subset of patients considered at increased risk for intervention (n = 123) were categorized, as such, based on a preexisting history of ischemic coronary artery disease, with documentation of myocardial infarction (60%) or congestive heart failure (35%), or due to the presence of chronic obstructive disease (21%), liver disease, or malignancy. Results Perioperative mortality (30-day) was 6.5% in the increased-risk patients as compared to 1.8% among those classified as low risk (P = NS). There was no difference between groups in age (74 ± 9 years vs. 72 ± 6 years; mean ± SD), surgical time (235 ± 95 minutes vs. 219 ± 84 minutes), blood loss (457 ± 432 mL vs. 351 ± 273 mL), postoperative hospital stay (4.8 ± 3.4 days vs. 4.0 ± 3.9 days), or days in the ICU (1.3 ± 1.8 days vs. 0.5 ± 1.6 days). Patients at increased risk of intervention had larger aneurysms than low-risk patients (59 ± 13 mm vs. 51 ± 14 mm;P < .05). Stent grafts were successfully implanted in 116 (95%) increased-risk versus 107 (95%) low-risk patients (P = NS). Conversion rates to open operative repair were similar in increased-risk and low-risk groups at 3% and 5%, respectively. The initial endoleak rate was 22% versus 20%, based on the first CT performed (either at discharge or 1 month;P = NS). To date

    Abdominal ultrasonography was performed in six adult captive caracals (Caracal caracal) to describe the normal abdominal ultrasonographic anatomy. Consistently, the splenic parenchyma was hyperechoic to the liver and kidneys. The relative echogenicity of the right kidney's cortex was inconsistent to the liver. The gall bladder was prominent in five animals and surrounded by a clearly visualized thin, smooth, regular echogenic wall. The wall thickness of the duodenum measured significantly greater compared with that of the jejunum and colon. The duodenum had a significantly thicker mucosal layer compared with that of the stomach. Such knowledge of the normal abdominal ultrasonographic anatomy of individual species is important for accurate diagnosis and interpretation of routine health examinations.

  11. Diagnostic peritoneal lavage in evaluating acute abdominal pain.

    1975-06-01

    A study was performed to determine the value of peritoneal lavage in the acute abdomen not related to trauma. Lavage was performed in 33 patients in the evaluation of abdominal pain of sufficient degree to warrant consideration for surgical intervention. Peritoneal lavage was truly positive or truly negative in 64% of the cases. It showed false negative results in 28% and false positive results in 8%. The lavage was most accurate in the evaluation of appendicitis, colonic disease, and intra abdominal bleeding. It was highly inaccurate in the evaluation of cholecystitis and peptic ulcer disease. It was concluded that the peritoneal lavage can be a useful adjunct in the evaluation of patients with abdominal pain and should be considered in difficult diagnostic problems but not routinely employed.

    Cerebrospinal fluid (CSF) shunting has been a mainstay in the treatment of hydrocephalus for many decades. With a reported 33,000 shunt placement procedures performed in the US annually, and a lifetime revision rate approaching 50%, abdominal radiologists must be familiar with the typical imaging appearance of an array of shunt complications. Complications related to the peritoneal portion of the shunt have been reported in up to 25% of patients. We present a comprehensive pictorial essay including computed tomography, conventional radiography, ultrasound, and nuclear medicine examples illustrating abdominal complications related to CSF shunting and a review of the current literature. The purpose of this pictorial essay is to provide multimodality imaging examples of CSF shunt complications and familiarize the abdominal imager with the spectrum of findings.

    The management of traumatic abdominal wall hernias is controversial. We performed a MEDLINE search and report a personal series of 10 patients. Cases were classified according to the cause of injury. Fifty-six percent were caused by car accidents and 14% by bicycle accidents. Diagnosis was clinical in 22% and surgical in 13% and intra-abdominal lesions were found in 67%. Treatment was delayed in 12%. In our series, 55% were lumbar hernias due to traffic accidents and all were associated with pelvic fracture. Treatment was delayed in 50%, including laparoscopic surgery with good results. In conclusion, traumatic hernias due to road traffic accidents are frequently associated with intra-abdominal lesions. The diagnostic technique of choice is computed tomography and delayed surgery (laparoscopy) is an effective option. PMID:18021624

    The bowel and the mesentery represent the third most frequently involved structures in blunt abdominal trauma after the liver and the spleen. Clinical assessment alone in patients with suspected intestinal and/or mesenteric injury from blunt abdominal trauma is associated with unacceptable diagnostic delays. Multi-detector computed tomography, thanks to its high spatial, time and contrast resolutions, allows a prompt identification and proper classification of such conditions. The radiologist, in fact, is asked not only to identify the signs of trauma but also to provide an indication of their clinical significance, suggesting the chance of conservative treatment in the cases of mild and moderate, non-complicated or self-limiting injuries and focusing on life-threatening conditions which may benefit from immediate surgical or interventional procedures. Specific and non-specific CT signs of bowel and mesenteric injuries from blunt abdominal trauma are reviewed in this paper.

    This study describes the treatment of two patients with recurrent, infected abdominal wall defects using bilateral delayed and tunnelled pedicled tensor fascia lata (TFL) myofascial flaps. TFL flaps were elevated and delayed for 4 weeks in both cases. In the second case, Parietex Composite mesh was positioned underneath the TFL flap and allowed to incorporate. After a delay of 4 weeks, the flaps were harvested and tunnelled subcutaneously to repair the abdominal wall defect. Both patients have stable repairs but had donor site seromas requiring drainage. Cadaver dissection was also performed to identify structures related to TFL flap harvest. We identified a variant of lateral femoral cutaneous nerve that traversed the TFL flap, necessitating meticulous dissection during surgery. In summary, we describe a new technique of incorporating mesh into the TFL prior to flap harvest for reconstruction of complex abdominal wall. PMID:22707661

    Rectal prolapse is rare in children and usually benign. However, there are various diseases that can be associated with it, such as cystic fibrosis or other causes of increased abdominal pressure. Here, we review the various underlying conditions that pediatricians or pediatric gastroenterologists should consider in the case of rectal prolapse. We report on three cases of children with a rectal prolapse and intra-abdominal tumors. Current recommendations and practice do not include a systematic check via abdominal imaging in cases of rectal prolapse. However, in some situations, imaging is indicated to detect a possible expansive process. Thus, in the presence of recurrent prolapse or of associated urinary or neurological signs, imaging is justified so as to allow for an early diagnosis and treatment of these neoplasms. Given its lack of radiation exposure and good sensitivity in children, ultrasound imaging is the first choice. PMID:27265581

    Background The survival rate of newborns with severe congenital abdominal wall defects has increased. After successfully addressing life-threatening complications, it is necessary to focus on the cosmetic and functional outcomes of the abdominal wall. Methods We performed a chart review of five cases treated in our institution. Results Five patients, ranging from seven to 18 years of age, underwent the following surgical approaches: simple approximation of the rectus abdominis fascia, the rectus abdominis sheath turnover flap, the placement of submuscular tissue expanders, mesh repair, or a combination of these techniques depending on the characteristics of each individual case. Conclusions Patients with severe congenital abdominal wall defects require individualized surgical treatment to address both the aesthetic and functional issues related to the sequelae of their defects.

    Abstract Surgery-induced acute postoperative pain may lead to prolonged convalescence. The present study was designed to investigate the effects of intraoperative dexmedetomidine on postoperative analgesia following abdominal colectomy surgeries. Eighty patients scheduled for abdominal colectomy surgery under general anesthesia were divided into 2 groups, which were maintained using propofol/remifentanil/dexmedetomidine (PRD) or propofol/remifentanil/saline (PRS). During surgery, patients in the PRD group had a lower bispectral index (BIS) value, which indicated a deeper anesthetic state, and a higher sedation score right after extubation than patients in the PRS group. During the first 24 hours post surgery, PRD patients consumed less morphine in patient-controlled analgesia (PCA) and had a lower score in the visual analog scale (VAS) testing than their controls from the PRS group. Intraoperative administration of dexmedetomidine appears to promote the analgesic property of morphine-based PCA in patients after abdominal colectomy. PMID:26376397

    Although uncommon, lead poisoning should be considered as a differential diagnosis in cases of unexplained acute abdominal pain in both adults and children. We present the case of a 35-year-old Asian male who presented with abdominal pain and constipation secondary to lead poisoning. Initially, the source of lead exposure was not apparent; this was later found to be due to ingestion of an Ayurvedic herbal medicine for the treatment of infertility. Lead poisoning due to the ingestion of Ayurvedic remedies is well described. We discuss the diagnosis, pathophysiology and treatment of lead poisoning. This case illustrates one of the rarer medical causes of acute abdominal pain and emphasizes the need to take a thorough history (including specific questioning regarding the use of over-the-counter and traditional/ herbal remedies) in cases of suspected poisoning or drug toxicity.

    Adrenal hemangioma is an extremely rare benign and non-functioning neoplasm of the adrenal gland. We report a case of a 71-year-old woman admitted for intermittent abdominal pain and abdominal distension associated with vomiting and chronic constipation for 5 years. Physical examination revealed a large abdominal mass. Both computed tomography scan and magnetic resonance imaging suggested hemangioma in the right lobe of the liver. Laboratory examinations and tumour markers were within normal limits, except for hypochromic microcytic anemia. The mass was removed intact by conventional surgery and histopathology revealed a cavernous hemangioma of the adrenal gland with no signs of malignancy. Surgical resection was curative, with no recurrence at the 2-year follow-up. PMID:26600897

    The closure of a temporary stoma involves 2 different surgical procedures: the stoma reversal procedure and the abdominal wall reconstruction of the stoma site. The management of the abdominal wall has different areas that should be analyzed such us how to avoid surgical site infection (SSI), the technique to be used in case of a concomitant hernia at the stoma site or to prevent an incisional hernia in the future, how to deal with the incision when the stoma reversal procedure is performed by laparoscopy and how to close the skin at the stoma site. The aim of this paper is to analyze these aspects in relation to abdominal wall reconstruction during a stoma reversal procedure.

    Abdominal emergencies can also be operated on through the laparoscopic approach: the approach can be diagnostic laparoscopy, surgery assisted by laparoscopy or laparotomy directed according to the findings of the laparoscopy. The general contraindications refer above all to the state of haemodynamic instability of the patient and to seriously ill patients (ASA IV). In the absence of any specific counter-indications for the specific laparoscopic procedure to be carried out, many abdominal diseases requiring emergency surgery can be performed with the laparoscopic approach. The most frequent indications are appendicitis, acute colecistitis, gastroduodenal perforation, occlusion of the small intestine, and some abdominal traumas. With a correct selection of patients and the appropriate experience of the surgeon, the results are excellent and better than open surgery (less infection of the wound, complications, hospital stay and postoperative pain). A detailed explanation is given of the basic aspects of the surgical technique in the most frequent procedures of emergency laparoscopy.

    Dual energy computed tomography (CT) is an imaging technique based on data acquisition at two different energy settings. Recent advances in CT have allowed data acquisition and almost simultaneously analysis of two spectra of X-rays at different energy levels resulting in novel developments in the field of abdominal imaging. This technique is widely used in cardiovascular imaging, especially for pulmonary embolism work-up but is now also increasingly developed in the field of abdominal imaging. With dual-energy CT it is possible to obtain virtual unenhanced images from monochromatic reconstructions as well as attenuation maps of different elements, thereby improving detection and characterization of a variety of renal, adrenal, hepatic and pancreatic abnormalities. Also, dual-energy CT can provide information regarding urinary calculi composition. This article reviews and illustrates the different applications of dual-energy CT in routine abdominal imaging.

    Most cases of abdominal lymphangioma are asymptomatic. However, patients may occasionally present with acute abdomen because of an intestinal obstruction or peritonitis caused by infected cysts, hemorrhaging, and/or torsion. These conditions may differ based on the location of the lymphangioma and do not always require emergency surgery. This report presents two cases of abdominal lymphangioma derived from the omentum, which required emergency surgery because of severe abdominal distension and peritonitis caused by torsion, respectively. In contrast, another case of retroperitoneal lymphangioma presented with acute abdomen and underwent elective surgery after conservative therapy for peritonitis. Elective surgery is acceptable if the symptoms are controllable under conservative therapy. However, it is important not to overlook the possible lethal complications such as intestinal and/or urological obstruction, aggressive peritonitis, and torsion of the cyst, which require emergency surgery.

    Cystic lymphangiomas are benign vascular tumors which are most often seen in young children. They are considered to be congenital malformations stemming from sequestration of lymphatic tissue. The authors report 15 cases of abdominal location and detail the findings of imaging in the etiologic and topographic diagnosis of these lesions. The initial incidents were essentially the discovery of a palpable abdominal mass, and more rarely, an acute gastrointestinal complication. There was also one case of prenatal diagnosis. Plain films provide only indirect signs related to the displacement of neighboring organs. Ultrasonography permits the etiologic diagnosis by showing an often voluminous, septated cyst. The intra- or retroperitoneal location of the lesion is sometimes difficult to determine by sonography, in which case CT scanning is usually adequate. For abdominal locations, percutaneous sclerosis is not available, and surgical removal is the only treatment for this disorder. The topography of the lesion and the involvement of retroperitoneal structures is important to determine.

  6. Monocytes, Macrophages and Other Inflammatory Mediators of Abdominal Aortic Aneurysm.

    2015-01-01

    Macrophages early invade the forming abdominal aortic aneurysm (AAA) and greatly contribute to its pathogenesis. Recent findings have shown that Ly-6C(high) and Ly-6C(low) monocytes are rapidly mobilized from the splenic reservoir in response to angiotensin II infusion and sequentially infiltrate the abdominal aorta. The first wave of Ly-6C(high) monocytes prevails in the aorta and promotes the accumulation of inflammatory macrophages, which most likely cause irreversible changes in the abdominal aorta. In this review, we discuss the current knowledge on the cellular mechanisms that initiate AAA in mice. We particularly focus on the role of monocyte and macrophage subsets during the early steps of the aneurysmal process. PMID:26306839

    A 12-year-old, neutered female, Siberian husky, was presented with a 6-months history of progressive abdominal distension, anorexia, and weight loss. The dog appeared normal on physical examination except for marked abdominal distension. A fluid wave was balloted strongly suggesting an abdominal effusion. Ultrasound examination confirmed this clinical finding. Results of the CBC included mild nonregenerative anemia, with an RBC count of 4.9 × 10(6)/µL (reference interval 5.5-8.5 × 10(6)/µL), hemoglobin concentration of 12 g/dL (reference interval 12-18 g/dL), HCT of 36% (reference interval 37-55%), and reticulocytes <60,000/µL. No abnormalities in serum chemistry were detected.

    [Purpose] The purpose of this study was to investigate the effective strength levels of abdominal muscle contraction using the bracing contraction method. [Subjects] The experiment was conducted with 31 healthy male (M=15) and female (F=16) adults attending D University in Busan; all participants had less than obesity level BMI (BMI<30). [Methods] Bracing contraction was performed by the subjects in the hook-lying position at maximum and minimum pressure levels, five times each, using a Pressure Biofeedback Unit (PBU), and the mean measurement value was calculated. The maximum pressure level was set at 100% and the half maximum pressure level was set at 50%. Each subject's left and right abdominal muscle thicknesses were then measured by ultrasound imaging in each state: at rest, 100% contraction, and 50% contraction. [Results] No significant differences were found between the left and right sides of the transversus abdominis (TrA) at rest, 50%, or 100% contraction. The external oblique abdominis (EO) and internal oblique abdominis (IO) showed no significant difference at rest or at the 50% contraction. However, a significant difference was noted at 100% contraction for the EO and IO. [Conclusion] Application of abdominal contraction using bracing can achieve symmetry in the left and right abdominal muscles at less than the maximum contractile strength. The occurrence of asymmetry in the left and right abdominal muscles at the maximum contractile strength suggests that the most suitable contractile strength in this exercise is less than the maximum contractile strength.

    A 78 -year-old man with rectal cancer underwent abdominoperineal resection of the rectum. In the postoperative period, the patient experienced wound infection, leading to an abdominal wall hernia. Two years following surgery, a rise in the serum CEA level was seen. A metastatic tumor was detected in the right lung on chest CT. VATS right lung inferior lobe segmental resection was performed. After lobectomy, the serum CEA level continued to increase. Another metastatic tumor was detected in the right lung on chest CT. Chemotherapy with capecitabine, oxaliplatin, and bevacizumab was commenced. The erosive part of the abdominal wall scar hernia extended during the nine weeks of chemotherapy. The chemotherapy was then discontinued. In the follow-up CT scan, a right pleural recurrence, local recurrence in the pelvis, and a liver metastasis were detected. Chemotherapy was re-introduced 3 years after surgery. The erosive part of the abdominal wall hernia again began to spread with chemotherapy recommencement. Four months after restarting chemotherapy, the hernia ruptured, with a loop of the small intestine protruding out of it. The patient covered this with a sheet of vinyl and was taken by the ambulance to our hospital. The erosive part of the abdominal wall hernia had split by 10 cm, and a loop of the small intestine was protruding. As ischemia of the small intestine was not observed, we replaced it into the abdominal cavity, and performed a temporary suture repair of the hernia sac. Following this, bevacizumab was discontinued, and the erosive part reduced. We performed a radical operation for abdominal wall scar hernia repair 11 weeks after the discontinuation of bevacizumab.

    It remains unclear whether abdominal obesity increases cardiovascular disease (CVD) risk independent of the metabolic abnormalities which often accompany it. Therefore, the objective of the current study was to evaluate the independent effects of abdominal obesity versus metabolic syndrome and diabetes on the risk for incident coronary heart disease and stroke. The Framingham Offspring, Atherosclerosis Risk in Communities, and Cardiovascular Health studies were pooled to assess the independent effects of abdominal obesity (waist circumference >102 cm for men and >88 cm for women) versus metabolic syndrome (excluding the waist circumference criterion) and diabetes on risk for incident coronary heart disease and stroke in 20,298 men and women aged ≥45 years. The average follow-up was 8.3 (standard deviation 1.9) years. There were 1,766 CVD events. After adjustment for demographic factors, smoking, alcohol intake, number of metabolic syndrome components and diabetes, abdominal obesity was not significantly associated with an increased risk of CVD (hazard ratio [95% confidence interval] 1.09 [0.98, 1.20]). However, after adjustment for demographics, smoking, alcohol intake, and abdominal obesity, having 1–2 metabolic syndrome components, the metabolic syndrome, and diabetes were each associated with a significantly increased risk of CVD (2.12 [1.80, 2.50], 2.82 [1.92, 4.12] and 5.33 [3.37, 8.41], respectively). Although abdominal obesity is an important clinical tool for identification of individuals likely to possess metabolic abnormalities, these data suggest that the metabolic syndrome and diabetes are considerably more important prognostic indicators of CVD risk.

    A raised serum amylase concentration, at least four times the upper limit of normal (ULN), is used to support the diagnosis of acute pancreatitis in a patient presenting with abdominal pain. The authors report a case of toxic shock syndrome complicated by a raised serum amylase concentration that peaked at 50 times the ULN in a patient with recurrent abdominal pain. The commonest cause of hyperamylasaemia is pancreatic; however, further investigation of serum lipase and amylase isoenzyme studies found this to be of salivary origin and attributable to soft tissue inflammation of the salivary gland. This case highlights the need to consider non-pancreatic causes of hyperamylasaemia. PMID:22767564

    An adult Bengal tiger (Panthera tigris tigris) housed in an outdoor sanctuary in Florida exhibited vomiting, diarrhea, and weight loss. A clinical workup did not reveal the source of the clinical signs and antibiotic therapy was unrewarding. Radiographs revealed the presence of an abdominal mass. The tiger died during an immobilization for a follow-up clinical examination. A necropsy was performed and tissue samples of intestine and mesenteric lymph nodes were submitted for histopathologic diagnosis. A pyogranulomatous panenteritis and lymphadenitis with intralesional hyphae led to a presumptive etiologic diagnosis of intestinal/abdominal pythiosis. The diagnosis of pythiosis was confirmed by serology and immunoblotting.

    In the early 1980s, we analyzed the metabolic profile of 930 men and women and concluded that an abdominal distribution of fat for a given BMI is associated with increased insulin resistance and risk of developing type 2 diabetes and cardiovascular disease. The correlation between abdominal fat and metabolic dysfunction has since been validated in many studies, and waist circumference is now a criterion for the diagnosis of metabolic syndrome. Several mechanisms for this relationship have been postulated; however, we now know that visceral fat is only one of many ectopic fat depots used when the subcutaneous adipose tissue cannot accommodate excess fat because of its limited expandability.

    An infected aortic aneurysm, or mycotic aneurysm, is a rare arterial dilatation due to destruction of the infected vessel wall. Common pathogens resulting in an infected aortic aneurysm are Salmonella and Clostridium species, as well as Staphylococcus aureus; Morganella morganii, on the other hand, is very rare. An infected abdominal aortic aneurysm has tendencies to grow rapidly and to rupture. The mortality rate is high in patients undergoing emergent surgical intervention. We report the case of a 65-year-old man who presented with an infected abdominal aortic aneurysm caused by M. morganii. A high index of suspicion and imaging tests are necessary in order to diagnose an infected aortic aneurysm.

    Periostitis pubis is a clinical syndrome previously undescribed in the literature. It is characterized by lower abdominal pain that may have persisted for several weeks to several years. Physical findings are limited to tenderness in one of the lower abdominal quadrants and over the os pubis on the affected side. The diagnosis can be confirmed by injecting lidocaine hydrochloride into the area of point tenderness over the os pubis, which should relieve tenderness in both sites. An elaborate laboratory workup is not necessary. The condition can be cured with an injection of prednisolone tebutate at the site of tenderness over the os pubis.

    Damage to the fibrinolytic system preventing the resolution of temporary fibrinous adhesions was repeatedly mentioned as an etiological factor in the process of adhesion formation. We experimentally induced abdominal adhesions in rats by gentle scraping of the entire small bowel. Severe adhesions, sometimes accompanied by intestinal obstruction, developed in all of the control animals. Urokinase, a commonly used and potent fibrinolytic agent and a known plasminogen activator, was administered intragastrically, intraperitoneally, or intravenously at various doses ranging from 5,000 to 100,000 U/kg. Urokinase had no effect on the prevention of abdominal adhesions, nor did it reduce the severity or frequency of adhesion formation. PMID:4043158

    Ultrasound examinations were done to evaluate clinically palpable abdominal masses in 125 children. The examinations were normal in 21 patients. In 15 patients, the clinically palpable masses were actually anterior abdominal wall abscesses or hematomas. Final diagnosis was available in 87 of 89 patients with intraabdominal masses detected on ultrasound. The majority (71%) were retroperitoneal masses where two-thirds were of renal origin. Ultrasound diagnosis was correct in 68 patients (78%). All cases of hydronephrosis were correctly diagnosed based on characteristic ultrasound appearances. Correct diagnoses of all cases of adrenal hematoma, psoas abscess, liver hematoma, liver abscess and one case of liver metastases were achieved with correlation of relevant clinical information.

    Blunt injury of the abdominal aorta is highly fatal. We present an unusual case of an osteophyte impaling the abdominal aorta treated by endovascular repair. A 77-year-old man sustained a thoracolumbar fracture-dislocation with posterior aortic rupture between his celiac and superior mesenteric artery origins. His aortic injury was treated with a stent graft, excluding the celiac origin. He was dismissed on postoperative day 6. At 6 months, he had returned to most preinjury activities, and at 2-year follow-up, he continues to have good functional outcome. Endovascular repair may be successfully employed in select aortic injuries in hemodynamically stable patients.

    Abdominal cocoon syndrome (ACS) is a rare cause of intestinal obstruction due to total or partial encapsulation of the small intestine by a fibrocollagenous membrane. Idiopathic ACS with abdominal cryptorchidism and greater omentum hypoplasia is even rarer clinically. We successfully treated a 26-year-old male case of small bowel obstruction with acute peritonitis. He was finally diagnosed with idiopathic ACS with unilateral abdominal cryptorchidism and greater omentum hypoplasia during exploratory laparotomy. He then underwent enterolysis, cryptorchidectomy, and appendectomy. He recovered gradually from the operations and early postoperative inflammatory ileus. There has been no recurrence of intestinal obstruction since the operation, and he is still in follow-up. We analyzed his clinical data and retrospectively reviewed the literature, and our findings may be helpful for the clinical diagnosis and treatment on ACS. PMID:27239122

    The function of the urinary bladder is partly controlled by parasympathetic preganglionic neurons (PPNs) of the sacral parasympathetic nucleus (SPN). Our recent work demonstrated that endomorphin-2 (EM-2)-immunoreactive (IR) terminals form synapses with μ-opioid receptor (MOR)-expressing PPNs in the rat SPN. Here, we examined the effects of EM-2 on excitatory synaptic transmission and the neuronal excitability of the PPNs in young rats (24–30 days old) using a whole-cell patch-clamp approach. PPNs were identified by retrograde labeling with the fluorescent tracer tetramethylrhodamine-dextran (TMR). EM-2 (3 μM) markedly decreased both the amplitude and the frequency of the spontaneous and miniature excitatory postsynaptic currents (sEPSCs and mEPSCs) of PPNs. EM-2 not only decreased the resting membrane potentials (RMPs) in 61.1% of the examined PPNs with half-maximal response at the concentration of 0.282 μM, but also increased the rheobase current and reduced the repetitive action potential firing of PPNs. Analysis of the current–voltage relationship revealed that the EM-2-induced current was reversed at −95 ± 2.5 mV and was suppressed by perfusion of the potassium channel blockers 4-aminopyridine (4-AP) or BaCl2 or by the addition of guanosine 5′-[β-thio]diphosphate trilithium salt (GDP-β-S) to the pipette solution, suggesting the involvement of the G-protein-coupled inwardly rectifying potassium (GIRK) channel. The above EM-2-invoked inhibitory effects were abolished by the MOR selective antagonist D-Phe-Cys-Tyr-D-Trp-Orn-Thr-Pen-Thr-NH2 (CTOP), indicating that the effects of EM-2 on PPNs were mediated by MOR via pre- and/or post-synaptic mechanisms. EM-2 activated pre- and post-synaptic MORs, inhibiting excitatory neurotransmitter release from the presynaptic terminals and decreasing the excitability of PPNs due to hyperpolarization of their membrane potentials, respectively. These inhibitory effects of EM-2 on PPNs at the spinal cord level may

    Tishchenko, V V

    2010-07-01

    The abdominal cavity adhesions (ACA) constitute frequent consequence of various abdominal cavity diseases and traumas and frequent cause of the abdominal adhesive disease and its complications. In spite of the known pathogenesis of ACA, the surgeons had failed throughout the decades of years to find out the measures and methods of its prophylaxis. There are several causes of such a situation and the main of them is that ACA in its origin constitutes a philogenetically developed defense biologic reaction of organism. Because of the fact, that an organism constitutes the self-regulated biological system, any external inputs (including the treatment), directed on qualitative or quantitative signs of these reactions, meet systemic counteraction and become annihilated. The forced overcome of such a counteraction may cause the development of severe systemic disorders in organism. The only prophylactic measures against ACA, which were already tested throughout the time, are the tactical and technical methods, promoting the reduction of severity of morphological changes in peritoneum and abdominal organs, thus causing reduction of natural reaction of organism. When the adhesions formation is inevitable it is necessary to apply surgical methods of governing such a process, and omentoparietopexy may constitutes one of such methods.

    Pigmentation varies within and between species and is often adaptive. The amount of pigmentation on the abdomen of Drosophila melanogaster is a relatively simple morphological trait, which serves as a model for mapping the genetic basis of variation in complex phenotypes. Here, we assessed natural variation in female abdominal pigmentation in 175 sequenced inbred lines of the Drosophila melanogaster Genetic Reference Panel, derived from the Raleigh, NC population. We quantified the proportion of melanization on the two most posterior abdominal segments, tergites 5 and 6 (T5, T6). We found significant genetic variation in the proportion of melanization and high broad-sense heritabilities for each tergite. Genome-wide association studies identified over 150 DNA variants associated with the proportion of melanization on T5 (84), T6 (34), and the difference between T5 and T6 (35). Several of the top variants associated with variation in pigmentation are in tan, ebony, and bric-a-brac1, genes known to affect D. melanogaster abdominal pigmentation. Mutational analyses and targeted RNAi-knockdown showed that 17 out of 28 (61%) novel candidate genes implicated by the genome-wide association study affected abdominal pigmentation. Several of these genes are involved in developmental and regulatory pathways, chitin production, cuticle structure, and vesicle formation and transport. These findings show that genetic variation may affect multiple steps in pathways involved in tergite development and melanization. Variation in these novel candidates may serve as targets for adaptive evolution and sexual selection in D. melanogaster.

    Two pediatric patients with salmonella infections (one with typhoid fever and the second with salmonella C2 gastroenteritis), had a diffuse abdominal uptake of Ga-67 citrate. The possible explanation for this finding is discussed. Salmonella infection should be included as a cause in the differential diagnosis of diffuse accumulation of Ga-67 citrate.

    Abstract Kaposiform hemangioendothelioma (KH) is a rare vascular tumor of intermediate malignancy that occurs mainly in the childhood. Adult patients with KH are rare. Imaging findings of KH have rarely been reported before. We present magnetic resonance imaging (MRI), computed tomography (CT), and fluorine-18-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET)/CT findings in an adult patient with KH associated with lymphangiomatosis involving mesentery and ileum. A 22-year-old female complained of a 9-month history of intermittent melena, weakness, and palpitation. Laboratory tests revealed anemia and hypoproteinemia. Fecal occult blood test was positive. Abdominal enhanced MRI and CT showed a large abdominal mass involving mesentery and ileum. On enhanced MRI, there were many hypervascular nodules in the mass. On FDG PET/CT, the mass and the nodules showed slight FDG uptake. Small bowel capsule endoscopy showed numerous grape-shaped red nodules in the luminal wall of the involved ileum. The patient underwent resection of the abdominal mass and a segment of the ileum invaded by the abdominal mass. KH arising within lymphangiomatosis involving mesentery and ileum was confirmed by pathology. After surgery, the patient's symptoms improved. This is the first case of KH associated with lymphangiomatosis involving mesentery and ileum. In this case, the lymphangiomatosis overshadowed the small tumor nodules resulting in unusual imaging findings. Familiarity with these imaging findings is helpful for diagnosis and differential diagnosis of KH. PMID:26871848

  1. Primary closure of the abdominal wall after "open abdomen" situation.

    2013-01-01

    "Open abdomen" is a strategy used to avoid or treat abdominal compartment syndrome. It has reduced mortality both in trauma and non-trauma abdominal catastrophes but also has created a challenging clinical problem. Traditionally, open abdomen is closed in two phases; primarily with a free skin graft and later with a flap reconstruction. A modern trend is to close the abdomen within the initial hospitalization. This requires multi-professional co-operation. Temporary abdominal closure methods, e.g. negative pressure wound therapy alone or combined with mesh-mediated traction, have been developed to facilitate direct fascial closure. Components separation technique, mesh reinforcement or bridging of the fascial defect with mesh and perforator saving skin undermining can be utilized in the final closure if needed. These techniques can be combined. Choice of the treatment depends on the condition of the patient and size of the fascia and skin defect, and the state of the abdominal contents. In this paper we review the literature on the closure of an open abdomen and present the policy used in our institution in the open abdomen situations.

  2. Can Abdominal Wall Reconstruction Be Safely Performed Without Drains?

    The use of closed suction drains in the abdominal wall is a common practice in abdominal wall reconstruction (AWR) operations. Drains can be a conduit for bacteria and can cause pain and discomfort for patients after surgery. A single hernia program has implemented the principles of clinical quality improvement in an attempt to improve outcomes for hernia patients. An attempt at a process improvement was implemented to eliminate the use of drains in AWR by adapting the technique. A total of 102 patients undergoing AWR were included between 8/11 and 9/15 (49 months). Compared with the group before the attempt at eliminating the use of abdominal wall drains (8/11-9/13), the group of patients after the implementation of the attempted process improvement (9/13-9/15) had less wound and pulmonary complications, a shorter hospital stay, less time in the postanesthesia care unit, and less opioid use in the postanesthesia care unit as well as for the entire hospital stay. In this group of AWR patients, an attempt at process improvement that eliminated the use of drains led to improved outcomes. Abdominal wall drains may be able to be safely eliminated with appropriate technique adaptation for AWR. PMID:27657586

    Patient records were retrospectively analyzed to elucidate the characteristics of patients with colorectal cancer (CRC) diagnosed with screening abdominal ultrasound (US). Patients diagnosed with CRC using abdominal US [localized irregular wall thickening (W) or a hypoechoic mass with a hyperechoic mass (M)] were enrolled. The patients were subjected to colonoscopy and treated surgically between March, 2010 and January, 2015. A total of 5 men (aged 74.0±0.8 years) and 10 women (aged 73.0±12.0 years) were analyzed. Stratification was analyzed with abdominal US. The threshold value of wall thickness to diagnose CRC was investigated with receiver operating characteristic (ROC) curve analysis. The average wall thickness was 2.8±0.4 mm in the surrounding normal tissue and 12.7±5.2 mm in CRC (one-way analysis of variance, P<0.0001). The wall was significantly thicker in CRC compared with the normal colonic wall. The calculated threshold value was 4.3 mm for the diagnosis of CRC. Stratification was preserved in W, while it was lost in M (Chi-squared test, P=0.0196). The hemoglobin concentration was lower, while the C-reactive protein, carcinoembryonic antigen and carbohydrate antigen 19-9 levels were elevated above normal values. The threshold value was 4.3 mm for the diagnosis of CRC with abdominal US. PMID:27330768

  8. Abdominal muscle and quadriceps strength in chronic obstructive pulmonary disease

    PubMed Central

    Man, W; Hopkinson, N; Harraf, F; Nikoletou, D; Polkey, M; Moxham, J

    2005-01-01

    Background: Quadriceps muscle weakness is common in chronic obstructive pulmonary disease (COPD) but is not observed in a small hand muscle (adductor pollicis). Although this could be explained by reduced activity in the quadriceps, the observation could also be explained by anatomical location of the muscle or fibre type composition. However, the abdominal muscles are of a similar anatomical and fibre type distribution to the quadriceps, although they remain active in COPD. Cough gastric pressure is a recently described technique that assesses abdominal muscle (and hence expiratory muscle) strength more accurately than traditional techniques. A study was undertaken to test the hypothesis that more severe weakness exists in the quadriceps than in the abdominal muscles of patients with COPD compared with healthy elderly controls. Methods: Maximum cough gastric pressure and quadriceps isometric strength were measured in 43 patients with stable COPD and 25 healthy elderly volunteers matched for anthropometric variables. Results: Despite a significant reduction in mean quadriceps strength (29.9 kg v 41.2 kg; 95% CI –17.9 to –4.6; p = 0.001), cough gastric pressure was preserved in patients with COPD (227.3 cm H2O v 204.8 cm H2O; 95% CI –5.4 to 50.6; p = 0.11). Conclusions: Abdominal muscle strength is preserved in stable COPD outpatients in the presence of quadriceps weakness. This suggests that anatomical location and fibre type cannot explain quadriceps weakness in COPD. By inference, we conclude that disuse and consequent deconditioning are important factors in the development of quadriceps muscle weakness in COPD patients, or that activity protects the abdominal muscles from possible systemic myopathic processes.

    Irritable bowel syndrome (IBS) is a functional gastrointestinal (GI) disorder of unknown etiology. Although relatively common in children, how this condition affects brain structure and function in a pediatric population remains unclear. Here, we investigate brain changes in adolescents with IBS and healthy controls. Imaging was performed with a Siemens 3 Tesla Trio Tim MRI scanner equipped with a 32-channel head coil. A high-resolution T1-weighted anatomical scan was acquired followed by a T2-weighted functional scan. We used a surface-based morphometric approach along with a seed-based resting-state functional connectivity (RS-FC) analysis to determine if groups differed in cortical thickness and whether areas showing structural differences also showed abnormal RS-FC patterns. Patients completed the Abdominal Pain Index and the GI Module of the Pediatric Quality of Life Inventory to assess abdominal pain severity and impact of GI symptoms on health-related quality of life (HRQOL). Disease duration and pain intensity were also assessed. Pediatric IBS patients, relative to controls, showed cortical thickening in the posterior cingulate (PCC), whereas cortical thinning in posterior parietal and prefrontal areas were found, including the dorsolateral prefrontal cortex (DLPFC). In patients, abdominal pain severity was related to cortical thickening in the intra-abdominal area of the primary somatosensory cortex (SI), whereas HRQOL was associated with insular cortical thinning. Disease severity measures correlated with cortical thickness in bilateral DLPFC and orbitofrontal cortex. Patients also showed reduced anti-correlations between PCC and DLPFC compared to controls, a finding that may reflect aberrant connectivity between default mode and cognitive control networks.

    Objective: Penetrating atherosclerotic ulcer (PAU) of the aorta is defined as an atherosclerotic lesion with ulceration of the aortic intima and media and rupture of the internal elastic lamina. PAU induced aortic dissection, aortic rupture, and secular aortic aneurysm and typically occurs in elderly hypertensive patients with severe atherosclerosis. Although it has been reported that atherosclerosis similarly occurs in the abdominal aorta, its natural history and treatment are still unclear. This study investigated the clinical features, natural history, and treatment of PAU of the abdominal aorta. Method:Between April 2006 and March 2009, 4 diagnoses of PAU in the abdominal aorta were made by computed tomography (CT) and magnetic resonance imaging (MRI). These 4 cases were analyzed along with 61 previously reported cases from the literature with diagnoses of PAU in the abdominal aorta, aortic rupture, and isolated abdominal aortic dissection over the past 15 years, giving a total of 65 cases. Results:The patients were men with an average age of 63.5 years. All 4 had hypertension, and 2 had concomitant coronary artery disease. Two patients were asymptomatic, and the other 2 were symptomatic and transmural rupture had occurred. All diagnoses were made by CT and MRI. All 4 patients underwent open surgery with a knitted Dacron graft, with no postoperative deaths. In the literature, 53% of cases were symptomatic, including pain (40%, n = 26), shock (4.6%, n = 3), and lower limb embolism (9.2%, n = 6). The remaining 40% of cases were asymptomatic (n = 26). Six patients were treated medically, while 58 patients underwent surgery, with 2 postoperative deaths. Conclusion:We suggest that surgical treatment (open surgery or endovascular stent grafting) should be performed to prevent an aortic catastrophe such as intramural hematoma, dissection, or rupture.

    Abdominal surgery-induced postoperative gastric ileus is well established to induce Fos expression in specific brain nuclei in rats within 2-h after surgery. However, the phenotype of activated neurons has not been thoroughly characterized. Nesfatin-1 was recently discovered in the rat hypothalamus as a new anorexigenic peptide that also inhibits gastric emptying and is widely distributed in rat brain autonomic nuclei suggesting an involvement in stress responses. Therefore, we investigated whether abdominal surgery activates nesfatin-1-immunoreactive (ir) neurons in the rat brain. Two hours after abdominal surgery with cecal palpation under short isoflurane anesthesia or anesthesia alone, rats were transcardially perfused and brains processed for double immunohistochemical labeling of Fos and nesfatin-1. Abdominal surgery, compared to anesthesia alone, induced Fos expression in neurons of the supraoptic nucleus (SON), paraventricular nucleus (PVN), locus coeruleus (LC), Edinger-Westphal nucleus (EW), rostral raphe pallidus (rRPa), nucleus of the solitary tract (NTS) and ventrolateral medulla (VLM). Double Fos/nesfatin-1 labeling showed that of the activated cells, 99% were nesfatin-1-immunoreactive in the SON, 91% in the LC, 82% in the rRPa, 74% in the EW and VLM, 71% in the anterior parvicellular PVN, 47% in the lateral magnocellular PVN, 41% in the medial magnocellular PVN, 14% in the NTS and 9% in the medial parvicellular PVN. These data established nesfatin-1 immunoreactive neurons in specific nuclei of the hypothalamus and brainstem as part of the neuronal response to abdominal surgery and suggest a possible implication of nesfatin-1 in the alterations of food intake and gastric transit associated with such a stressor.

    Park, Hyunjin; Hero, Alfred; Bland, Peyton; Kessler, Marc; Seo, Jongbum; Meyer, Charles

    A good abdominal probabilistic atlas can provide important information to guide segmentation and registration applications in the abdomen. Here we build and test probabilistic atlases using 24 abdominal CT scans with available expert manual segmentations. Atlases are built by picking a target and mapping other training scans onto that target and then summing the results into one probabilistic atlas. We improve our previous abdominal atlas by 1) choosing a least biased target as determined by a statistical tool, i.e. multidimensional scaling operating on bending energy, 2) using a better set of control points to model the deformation, and 3) using higher information content CT scans with visible internal liver structures. One atlas is built in the least biased target space and two atlases are built in other target spaces for performance comparisons. The value of an atlas is assessed based on the resulting segmentations; whichever atlas yields the best segmentation performance is considered the better atlas. We consider two segmentation methods of abdominal volumes after registration with the probabilistic atlas: 1) simple segmentation by atlas thresholding and 2) application of a Bayesian maximum a posteriori method. Using jackknifing we measure the atlas-augmented segmentation performance with respect to manual expert segmentation and show that the atlas built in the least biased target space yields better segmentation performance than atlases built in other target spaces.

    2014-11-01

    This hypothesis proposes pre-eclampsia is caused by intra-abdominal hypertension in pregnancy. Sustained or increasing intra-abdominal pressure ⩾12mmHg causes impaired venous return to the heart, systemic vascular resistance, ischemia reperfusion injury, intestinal permeability, translocation of lipopolysaccharide endotoxin to the liver, cytotoxic immune response, systemic inflammatory response, pressure transmission to thoracic and intra-cranial compartments, and multi-organ dysfunction. This hypothesis is predicated on Pascal's law, evidence founded in the intra-abdominal hypertension literature, and the adapted equation ΔIAP-P=ΔIAVF/Cab, where ΔIAP-P=change in intra-abdominal pressure in pregnancy, ΔIAVF=change in intra-abdominal vector force (volume and force direction) and Cab=abdominal compliance. Factors causing increased intra-abdominal pressure in pregnancy include: progressive uterine expansion, obstetrical factors that increase intra-uterine volume excessively or acutely, maternal anthropometric measurements that affect intra-abdominal pressure thresholds, maternal postures that increase abdominal force direction, abdominal compliance that is decreased, diminished with advancing gestation, or has reached maximum expansion, habitation at high altitude, and rapid drops in barometric pressure. We postulate that the threshold for lipopolysaccharide translocation depends on the magnitude of intra-abdominal pressure, the intestinal microbiome complex, and the degree of intestinal permeability. We advance that delivery cures pre-eclampsia through the mechanism of abdominal decompression.

Bariatric operations involve both special fields too. Plastic surgeons sometimes use skin and muscle compartments of the abdominal wall for reconstruction at other regions of the body. This article aims to i) give an overview about functional, anatomic and clinical aspects as well as the potential of surgical interventions in plastic surgery. General/abdominal/vascular surgeons can benefit from this in their surgical planning and competent execution of their own surgical interventions with limited morbidity/lethality and an optimal, in particular, functional as well as aesthetic outcome, ii) support the interdisciplinary work of general/abdominal/vascular and plastic surgery, and iii) provide a better understanding of plastic surgery and its profile of surgical interventions and options.

    The typical presentation of intussusception includes intermittent severe abdominal pain, vomiting, rectal bleeding, and the presence of an abdominal mass. We present a case of intussusception after abdominal blunt trauma along with a literature review. A 4-year-old girl was admitted to the emergency department after a bicycle accident. She complained of progressively worsening abdominal pain, but there was no vomiting, fever, bloody stool, or abdominal mass. She was finally diagnosed with traumatic intussusception by ultrasonography and treated with air reduction. Because the typical symptoms are unusual in traumatic intussusception, close attention must be paid to avoid a delayed diagnosis. PMID:27752618

    Thrombosis due to abdominal aortic aneurysm is a rare condition that causes high mortality. Transient ischemic attack of the spinal cord can occur as a result of trash emboli from thrombus in abdominal aortic aneurysm. This condition generally occurs during operation of abdominal aortic aneurysm; very rarely, it can also be seen in laminated abdominal aortic aneurysm. Here, we present a case of a patient presenting with bilateral lower extremity paralysis resulting from transient ischemic attack of the spinal cord due to infrarenal abdominal aortic aneurysm.

    This paper presents a method for 3-D segmentation of abdominal aortic aneurysm from computed tomography angiography images. The proposed method is automatic and requires minimal user assistance. Segmentation is performed in two steps. First inner and then outer aortic border is segmented. Those two steps are different due to different image conditions on two aortic borders. Outputs of these two segmentations give a complete 3-D model of abdominal aorta. Such a 3-D model is used in measurements of aneurysm area. The deformable model is implemented using the level-set algorithm due to its ability to describe complex shapes in natural manner which frequently occur in pathology. In segmentation of outer aortic boundary we introduced some knowledge based preprocessing to enhance and reconstruct low contrast aortic boundary. The method has been implemented in IDL and C languages. Experiments have been performed using real patient CTA images and have shown good results.

    Low birth weight is associated with obesity in later life and a more central fat distribution has a positive correlation with cardiovascular disease. However, the correlation between visceral adiposity in newborns and birth size is unknown. We measured the visceral adiposity in 118 newborns using the abdominal wall fat index (AFI), ratio between the maximum thickness of preperitoneal and the minimum thickness of subcutaneous fat evaluated by ultrasound. There was a weak negative correlation between AFI and birth weight (r = -0.197; P = 0.033) but not with birth length (r = -0.118; P = 0.201), body mass index (r = -0.138; P = 0.176) and abdominal circumference (r = 0.063; P = 0.497). In conclusion, we suggest that AFI is a useful parameter for evaluating the fat distribution in newborns and that visceral adiposity has a weak negative correlation with birth weight.

    Chylous ascites and coexistent chylothorax is a rare but important complication following retroperitoneal abdominal surgery. We report a 70-year-old male who developed gradual abdominal distension, chest tightness, and dyspnea five months after having an uncomplicated aortobifemoral bypass performed. Physical examination was consistent with a large right sided effusion and ascites which were confirmed by computed tomography. Thoracentesis yielded an opaque milky fluid with analysis consistent with a chylothorax with a paracentesis revealing fluid that was similar in both appearance and biochemistry. The patient failed initial conservative management so a chest tube was placed followed by chemical pleurodesis. We review the literature of the pathophysiology and treatment approach to such a pleural effusion. PMID:26635989

    An abdominal aortic aneurysm (AAA) is a dilatation of the aorta at the abdominal level, whose rupture is a life threatening complication. Recent treatment procedures of AAA consists in endovascular treatment with covered stent grafts. Despite improving design of these devices, this treatment is still associated with close to 25% of failure, due to persisting pressure into the excluded aneurysmal sac. The follow-up becomes thus crucial and demands frequent examinations (CT-scan, IRM) which are not so liable given the complications. In order to evaluate the post-operative period of an AAA treatment, we designed a communicative stent, comprising of an integrated pressure sensor. This paper presents the conception of a communicative sensor, the elaboration of a numerical model, and the development of an experimental testbench reproducing the aortic flux across an AAA and allowing the optimization and validation of the measurement principle.

    Magnetic resonance imaging (MRI) was performed in 20 patients with radiologically or surgically proven abdominal aortic aneurysms using a Siemens Magnetom scanner with a 0.35-T superconductive magnet. Of nine patients who underwent surgical repair, MRI correctly demonstrated the origin of the aortic aneurysm in nine and accurately determined the status of the iliac arteries in eight. Of 11 patients who did not have surgical repair, MRI findings correlated well with other radiologic studies. MRI was found to be more reliable than sonography in determining the relation between the aneurysm and the renal arteries as well as the status of the iliac arteries. Despite these advantages, the authors still advocate sonography as the screening procedure of choice in patients with suspected abdominal aortic aneurysms because of its lower cost and ease of performance. MRI should be reserved for patients who have had unsuccessful or equivocal sonographic examinations.

    [Purpose] The aim of this study was to investigate the influence of the craniocervical posture on abdominal muscle activities in hook-lying position. [Subjects] This study recruited 12 healthy young adults. [Methods] Each subject was asked to adopt a supine position with the hip and knee flexed at 60°. Surface electromyographic signals of transversus abdominis/internal oblique, rectus abdominis, and external oblique in different craniocervical postures (extension, neutral, and flexion) were compared. [Results] The transversus abdominis and rectus abdominis showed increased muscle activities in craniocervical flexion compared to craniocervical extension and neutral position. Greater muscle activities of the external oblique were seen in craniocervical flexion than in craniocervical extension. [Conclusion] Craniocervical flexion was found to be effective to increase the abdominal muscle activities. Consideration of craniocervical posture is recommended when performing trunk stabilization exercises. PMID:27065558

    Abdominal Marlex-mesh rectopexy was used for surgical treatment of rectal prolapse in 54 consecutive patients. Anal incontinence was observed in 43 patients (80%) before surgical treatment. The degree of anal incontinence was more severe in women as compared with men. Operative treatment corrected the pathologic anatomy effectively as only one recurrent prolapse developed. At the follow-up examination three patients had symptomless anal mucosal prolapse during maximal straining. 75% of the incontinent patients regained continence for faeces and the rest had some improvement in continence. Seventeen patients (31%) had postoperative constipation, that required lactulose treatment. In conclusion, abdominal Marlex-mesh rectopexy can be recommended as safe and effective treatment for rectal prolapse, despite some patients developing constipation and some remaining incontinent.

    Migration of a permanent pacemaker generator from their intramuscular pocket to the abdominal cavity is a less frequent, but potentially life-threatening complication. The authors present the case of a 69-year-old woman, who visited the emergency department of the clinic, with complains of non-specific abdominal symptoms. Her past medical history included a complete atrioventricular block diagnosed in 2009 during the mitral valve replacement and since then she had an epicardial permanent pacemaker; the pulse generator was placed into an intramuscular pouch created in the left subcostal region. Surprisingly, radiologic examinations showed that the generator migrated into the pouch of Douglas. Considering patient safety, first a new intracardiac pacemaker was implanted and then the migrated device was removed surgically. The patient was discharged on the seventh postoperative day.

    Endovascular treatment of the abdominal aortic aneurysm is consider an alternative to open surgery for high risk patients. Its goal is to exclude the aneurysm from the circulation by using an endoprothesis introduced from a femoral approach. Patients must be strictly selected to avoid possible complications. The most frequent limitation is related to anatomic contraindications such as visceral arteries involved in the aneurysm. Fenestrated endograft have been recently developed to allow endovascular treatment when anatomic features contraindicate classic endovascular procedures. Fenestrated endograft have holes that match with the origin of the visceral arteries maintaining its potency. In this paper we report the endovascular treatment of an abdominal aortic aneurysm by using a fenestrated endoprothesis in a patient whose left renal artery is originated from the aneurysm.

    Osteitis pubis is the most common inflammatory condition of the pubic symphysis and may present as acute abdominal, pelvic, or groin pain. Osteomyelitis pubis can occur concurrently and spontaneously with osteitis pubis. Primary care physicians should consider these conditions in patients presenting with abdominal and pelvic pain. A thorough history, including type of physical activity, and a focused physical examination will be useful, and imaging modalities may be helpful. A biopsy and culture of the pubic symphysis will usually confirm the diagnosis. Treatment for osteitis pubis generally involves rest and anti-inflammatory medications. Failure with this conservative treatment should alert the physician to the possibility of osteomyelitis, which needs treatment with antibiotics. Prognosis for recovery is excellent with definitive diagnosis and treatment. PMID:21461096

    The major goals of the poultry industry are to increase the carcass yield and to reduce carcass fatness, mainly the abdominal fat pad. The increase in poultry meat consumption has guided the selection process toward fast-growing broilers with a reduced feed conversion ratio. Intensive selection has led to great improvements in economic traits such as body weight gain, feed efficiency, and breast yield to meet the demands of consumers, but modern commercial chickens exhibit excessive fat accumulation in the abdomen area. However, dietary composition and feeding strategies may offer practical and efficient solutions for reducing body fat deposition in modern poultry strains. Thus, the regulation of lipid metabolism to reduce the abdominal fat content based on dietary composition and feeding strategy, as well as elucidating their effects on the key enzymes associated with lipid metabolism, could facilitate the production of lean meat and help to understand the fat-lowering effects of diet and different feeding strategies.

    Patterns in normal abdominal movement captured with medical imaging can be recognised by a trained radiologist but the process is time consuming. Abdominal adhesions present a diagnostic problem in which the radiologist is asked to detect abnormal movement that may be indicative of pathology. This paper postulates that the use of image analysis can augment the diagnostic abilities of the radiologist in respect of adhesions. Proof of concept experiments were conducted in-silico to explore the effectiveness of the technique. The results indicate that trained participants are accurate in their assessment of abnormalities when supplied with additional information from image analysis techniques. However without the additional information, participants made incorrect diagnoses on many occasions. ROC methods were used to quantify the outcomes of the in-silico experiment.

    Obesity has become widespread in America and has been associated as a risk factor for many illnesses. Adipose tissue (AT) content, especially visceral AT (VAT), is an important indicator for risks of many disorders, including heart disease and diabetes. Measuring adipose tissue (AT) with traditional means is often unreliable and inaccurate. CT provides a means to measure AT accurately and consistently. We present a fully automated method to segment and measure abdominal AT in CT. Our method integrates image preprocessing which attempts to correct for image artifacts and inhomogeneities. We use fuzzy cmeans to cluster AT regions and active contour models to separate subcutaneous and visceral AT. We tested our method on 50 abdominal CT scans and evaluated the correlations between several measurements.

    The benign cystic mesothelioma of the peritoneum is a rare lesion and is known for local recurrence. This is first case report of a rapidly developing massive abdominal tumor with histological finding of benign cystic mesothelioma (BCM). We describe a BCM arising in the retroperitoneal tis[sue on the right side, lifting ascending colon and cecum to the left side of abdomen. Patient was an active 58-year-old man who noticed a rapid abdominal swelling within a two month time period with a weight gain of 40 pounds. Patient had no risk factors including occupational (asbestos, cadmium), family history, social (alcohol, smoking) or history of trauma. We will discuss the clinical, radiologic, intra-operative, immunohistochemical, pathologic findings, and imaging six months after surgery. Patient has no recurrence and no weight gain on follow up visits and imaging.

    Hepatic echinococcosis is endemic in Israel, with about 90 new cases diagnosed each year. Although many are asymptomatic for years, 40% develop complications. We describe a man of 37 and women aged 22 and 35, respectively, in whom rupture of an echinococcal cyst followed minimal, blunt abdominal trauma. In each patient the rupture led to complications consisting of massive intra-abdominal bleeding in 1, diffuse peritonitis in another and cystocutaneous fistula with ureteral obstruction due to reactive retroperitoneal fibrosis in the third. All 3 underwent surgery to resolve the immediate complication, with no mortality. A striking feature was the disproportion between the stormy clinical presentation and the relatively innocent nature of the trauma. In only 1 of our cases was the correct preoperative diagnosis made, which in this condition depends primarily on a high index of suspicion.

    This is a retrospective study of 74 patients with penetrating injuries of the abdominal inferior vena cava; the cause of injury was gunshot in 91% and stabbing in 9%. Of the patients, 77% underwent lateral venorrhaphy, 5% underwent infrarenal ligation of the inferior vena cava (IVC), and 18% died perioperatively before any caval repair could be carried out. There was an overall perioperative mortality of 39%. Persistent shock, the site of the venous injury, particularly in the retrohepatic position, and the number of associated vascular injuries were directly related to mortality. Irrespective of the improvements in resuscitation and the various operative methods available, penetrating trauma of the abdominal IVC remains a life-threatening injury. PMID:8943628

    Accurate, rapid, and noninvasive health assessments are required to establish more appropriate endpoints in mouse cancer models where tumor size is not easily measured. We evaluated potential endpoints in mice with experimentally induced peritoneal lymphoma, an abdominal tumor model, by comparing body weight, body condition, and behavior with those of a control group of mice not developing lymphoma. Our hypothesis was that body weight would increase or plateau, whereas body condition and behavioral scores would decrease, as disease progressed. Results indicated that body weight did not differ significantly between the control and experimental groups, but the experimental group experienced significant decreases in both body condition and behavioral scores. Our results support the use of body condition and behavioral scoring as adjunctive assessment methods for mice involved in abdominal lymphoma tumor studies in which health may decline despite an increase or plateau in body weight.

  18. Abdominal fat weight and thickness as predictors of total body fat in broilers.

    In two experiments broilers of both sexes from two strains were reared to 16 weeks of age to determine how total body fat could be estimated and predicted from some carcase traits. In the first experiment, age, carcase weight and abdominal fat thickness were found to be significant factors in the prediction of total body fat weight estimated from abdominal fat weight. In the second experiment abdominal fat weight was the best predictor of total body fat weight, obtained by ether extraction of the minced whole carcase. Inclusion of abdominal fat weight in the prediction equation after carcase weight and abdominal fat thickness significantly improved the regression. If the carcase cannot be weighed and abdominal fat weight is not available, because of the more laborious nature of its determination, then the measurement of abdominal fat thickness can be useful in predicting the total body fat content.

    Prior experience with the rare combination of horseshoe kidney and significant atherosclerotic vascular disease suggests difficulty in intraoperative management, often requiring division of the renal isthmus or sacrifice of some renal tissue. Seven patients have been managed successfully over the past ten years at The Ohio State University Hospital. There were six men and one woman, ranging in age from 39 to 66 years. Of the five patients with abdominal aortic aneurysm, four had a pulsatile abdominal mass, three had abdominal pain, and one had back pain. The other two patients had progressively symptomatic aortoiliac disease. All seven patients had hypertension, easily controlled by medication. Critical diagnostic procedures are preoperative intravenous pyelogram (IVP) and abdominal aortic arteriogram. The IVP detected the previously unsuspected diagnosis in 100% of the cases. The arteriogram accurately located the aneurysm in relation to the renal vascular supply, and disclosed aberrant blood supply in three of four patients with aberrant vessels. All seven horseshoe kidneys were fused at the lower pole. The operative approach involves meticulous dissection of the aberrant blood supply to the kidneys, and mobilization of the isthmus for adequate retrorenal aortic exposure. In six of the seven patients, the grafts were placed posterior to the isthmus. There were no deaths, and there were no complications related to the presence of the horseshoe kidney. In three of the seven patients, hypertension improved. Patients with horseshoe kidney and aortic disease may be safely operated upon without damage to the kidney. IVP and selective angiography are essential to provide preoperative information. ImagesFig. 11. PMID:666380

    PurposeTo evaluate patients radiation exposure of abdominal C-arm cone beam computed tomography (CBCT).MethodsThis prospective study was approved by the institutional review board; written, informed consent was waived. Radiation exposure of abdominal CBCT was evaluated in 40 patients who underwent CBCT during endovascular interventions. Dose area product (DAP) of CBCT was documented and effective dose (ED) was estimated based on organ doses using dedicated Monte Carlo simulation software with consideration of X-ray field location and patients’ individual body weight and height. Weight-dependent ED per DAP conversion factors were calculated. CBCT radiation dose was compared to radiation dose of procedural fluoroscopy. CBCT dose-related risk for cancer was assessed.ResultsMean ED of abdominal CBCT was 4.3 mSv (95 % confidence interval [CI] 3.9; 4.8 mSv, range 1.1–7.4 mSv). ED was significantly higher in the upper than in the lower abdomen (p = 0.003) and increased with patients’ weight (r = 0.55, slope = 0.045 mSv/kg, p < 0.001). Radiation exposure of CBCT corresponded to the radiation exposure of on average 7.2 fluoroscopy minutes (95 % CI 5.5; 8.8 min) in the same region of interest. Lifetime risk of exposure related cancer death was 0.033 % or less depending on age and weight.ConclusionsMean ED of abdominal CBCT was 4.3 mSv depending on X-ray field location and body weight.
