    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.

    Full Text Available Repair of abdominal wall defects in the presence of contamination or infection is a significant problem. The loss of tissue warrants enforcement of the abdominal wall, preferably by autologous material. However, autologous repair often requires extensive surgery. This paper presents a review of available literature of placement of an acellular human dermis to repair an abdominal fascia defect, in contaminated as well as in non-contaminated surgical fields. It is illustrated with a case report that describes the successful reconstruction of an infected abdominal wall defect with a human acellular dermis allograft. A systematic literature review was undertaken with searches performed in the Pubmed and Cochrane databases for the period up till March 2009, using the search terms Alloderm [Substance Name], Hernia [Mesh] and the key words acellular dermis, acellular dermal matrix, human acellular dermal allograft and abdominal wall defect. To assess methodological quality, each article was subjected to a modification of the methodological index for non-randomized studies (MINORS according to Slim et al. Two items from the original index were not included because none of the studies selected had an unbiased assessment of the study end points and in none of the studies was a prospective calculation of the study size performed. Seventeen studies were included in the review. Data were extracted regarding study design, number of patients, surgical technique, followup period, contaminated or non-contaminated area of the fascia defect, mortality and morbidity (hemorrhage, seroma, wound dehiscence, infection of the operative procedure, the longterm results (removal of the graft, reherniation and bulging and level of evidencey.

    Many patients undergoing reconstructive surgery after mastectomy opt for reconstruction with the transverse rectus abdominis myocutaneous (TRAM) flap. Among the morbidities related to TRAM flap reconstruction is the development of abdominal wall contour abnormalities, including bulges or hernias. Several repair techniques at the flap abdominal wall donor site have been described for use at the time of flap harvest in an attempt to reduce the risk of such abdominal wall complications. For patients that develop abdominal wall contour abnormalities, numerous reconstructive options have been reported, with mixed results. Ten patients were identified as having abdominal wall contour abnormalities after a TRAM flap and underwent an extended mesh repair with external oblique muscle reinforcement. The mesh was secured to the bony landmarks of the lower abdomen and the abdominal wall fascia. All patients achieved complete resolution of abdominal wall bulging. In the follow-up period, no recurrences, infections, or seromas were noted. One patient, who failed an earlier repair at the inferior abdominal wall, reported symptoms consistent with a scar neuroma. Symptoms were treated successfully with gabapentin and a nonsteroidal anti-inflammatory drug. We propose a novel and reliable method of lower abdominal wall reconstruction for patients with post-TRAM flap abdominal wall contour abnormalities. This technique incorporates the use of a large Marlex mesh reinforced with bilateral external oblique muscle flaps. We report a series of 10 patients who have achieved resolution of their symptoms and have regained a natural, flat-appearing abdominal wall contour.

    Emergency repair of complicated abdominal wall hernias may be associated with worsen outcome and a significant rate of postoperative complications. There is no consensus on management of complicated abdominal hernias. The main matter of debate is about the use of mesh in case of intestinal resection and the type of mesh to be used. Wound infection is the most common complication encountered and represents an immense burden especially in the presence of a mesh. The recurrence rate is an important topic that influences the final outcome. A World Society of Emergency Surgery (WSES) Consensus Conference was held in Bergamo in July 2013 with the aim to define recommendations for emergency repair of abdominal wall hernias in adults. This document represents the executive summary of the consensus conference approved by a WSES expert panel. In 2016, the guidelines have been revised and updated according to the most recent available literature.

    In this study, 101 consecutive laparoscopic transabdominal preperitoneal hernia repairs (LTPR) were performed in 62 patients by a single surgeon. The series was begun in April 1991, and involved repair of 49 direct, 41 indirect, 4 femoral, 3 umbilical, 3 sliding, and 1 incisional hernias. Twelve cases were bilateral, eleven hernias were incarcerated, and fifteen hernias were recurrent. There were no intraoperative complications, and none of the procedures required conversion to open surgery. Patients experienced the following postoperative complications: transient testicular pain (1), transient anterior thigh paresthesias (2), urinary retention requiring TURP (1), and hernia recurrences (2). Follow up has ranged from 4 - 15 months and initial results have been encouraging.

    Permacol(R) mesh has shown promise when used in abdominal wall repair, especially in the presence of a contaminated surgical field. This biomaterial, derived from porcine dermis collagen, has proposed advantages over synthetic materials due to increased biocompatibility and reduced foreign body reaction within human tissues. However, we present a case report describing a patient who displayed rejection to a Permacol(R) mesh when used in the repair of abdominal wound dehiscence following an emergency laparotomy. Review of the English language literature using PubMed and Medline, showed only two previously published cases of explantation of Permacol(R) due to sepsis or wound breakdown. The authors believe this is the first case of severe foreign body reaction leading to rejection of Permacol(R). Both animal and human studies show conflicting evidence of biocompatibility. There are several reports of successful use of Permacol(R) to repair complex incisional herniae or abdominal walls in the presence of significant contamination. It appears from the literature that Permacol(R) is a promising material, but as we have demonstrated, it has the potential to evoke a foreign body reaction and rejection in certain subjects.

    Routine hernia repair surgery involves the implant of synthetic mesh. However, this type of procedure may give rise to pain and bowel incarceration and strangulation, causing considerable patient disability. The purpose of this study was to compare the long-term behaviour of three commercial meshes used to repair the partially herniated abdomen in New Zealand White rabbits: the heavyweight (HW) mesh, Surgipro(®) and lightweight (LW) mesh, Optilene(®), both made of polypropylene (PP), and a mediumweight (MW) mesh, Infinit(®), made of polytetrafluoroethylene (PTFE). The implanted meshes were mechanical and histological assessed at 14, 90 and 180 days post-implant. This behaviour was compared to the anisotropic mechanical behaviour of the unrepaired abdominal wall in control non-operated rabbits. Both uniaxial mechanical tests conducted in craneo-caudal and perpendicular directions and histological findings revealed substantial collagen growth over the repaired hernial defects causing stiffness in the repair zone, and thus a change in the original properties of the meshes. The mechanical behaviour of the healthy tissue in the craneo-caudal direction was not reproduced by any of the implanted meshes after 14 days or 90 days of implant, whereas in the perpendicular direction, SUR and OPT achieved similar behaviour. From a mechanical standpoint, the anisotropic PP-lightweight meshes may be considered a good choice in the long run, which correlates with the structure of the regenerated tissue.

    Full Text Available OBJECTIVE: The purpose of this study was to compare the mechanical properties, host responses and incorporation of porcine small intestine submucosa (PSIS and porcine acellular dermal matrix (PADM in a rat model of abdominal wall defect repair. MATERIALS AND METHODS: Prior to implantation, PSIS and PADM were prepared and evaluated in terms of structure and mechanical properties. Full-thickness abdominal wall defects were created in 50 Sprague-Dawley rats, and were repaired using either PSIS or PADM. Rats were sacrificed 1, 2, 4, 8 and 12 weeks post-repair and examined for herniation, infection, adhesions, contraction, and changes in the thickness and strength of the tissues incorporated at the defect sites. Histopathology and immunohistochemistry were performed to analyze inflammatory responses, collagen deposition and vascularization. RESULTS: PADM showed more dense collagen deposition and stronger mechanical properties than PSIS prior to implantation (P<0.01. However, the mechanical properties observed after integration with the surrounding native tissues was similar for PADM and PSIS. Both PADM and PSIS showed significant contraction by week 12. However, PADM tissue induced less adhesion and increased in thickness more slowly, and showed less infiltration by foreign giant cells, polymorphonuclear cells, and mononuclear cells. Improved remodeling of host tissue was observed after PSIS implantation, which was apparent from the orientation of bands of fibrous connective tissue, intermixed with newly formed blood vessels by Week 12. CONCLUSION: PSIS showed weaker mechanical properties prior to implantation. However, after implantation PSIS induced more pronounced host responses and showed better incorporation into host tissues than PADM.

    The aim of this study was to conduct a preclinical evaluation of the behaviour of a new type of abdominal LW prosthesis (Ciberlastic), which was designed with a non-absorbable elastic polyurethane monofilament (Assuplus, Assut Europe, Italy) to allow greater adaptability to mechanical area requirements and higher bio-mimicking with the newly formed surrounding tissues. Our hypothesis was that an increase in the elasticity of the mesh filament could improve the benefits of LW prostheses. To verify our hypothesis, we compared the short- and long-term behaviour of Ciberlastic and Optilene(®) elastic commercial meshes by repairing the partially herniated abdomen in New Zealand White rabbits. The implanted meshes were mechanically and histologically assessed at 14 and 180 days post-implant. We mechanically characterized the partially herniated repaired muscle tissue and also determined mesh shrinkage at different post-implant times. This was followed by a histological study in which the tissue incorporation process was analysed over time. The new prosthesis designed by our group achieved good behaviour that was similar to that of Optilene(®), one of the most popular LW prostheses on the market, with the added advantage of its elastic property. The mechanical properties are significantly lower than those of the polypropylene Optilene(®) mesh, and the new elastic mesh meets the basic mechanical requirements for positioning in the abdominal wall, which was also demonstrated by the absence of recurrences after implantation in the experimental model. We found that the growth of a connective tissue rich in collagen over the hernial defect and the proper deposit of the collagen fibres in the regenerated tissue substantially modified the original properties of the mesh, thereby increasing its biomechanical strength and making the whole tissue/mesh stiffer.

  6. Prosthetic abdominal wall hernia repair in emergency surgery: from polypropylene to biological meshes

    Directory of Open Access Journals (Sweden)

    2008-12-01

    Full Text Available Abstract The use of nonabsorbable prosthetic materials such as polypropylene, polyester, and ePTFE, have expanded and are now widely used in reparative surgery for abdominal wall hernias. There are still difficulties to find correct indication for prosthetic implant in emergency hernia surgery: as a matter of fact there is still a great debate if to use non-absorbable prostheses in potentially or truly infected operating fields [e.g. after intestinal resections]. All these problems can be avoided with the use of absorbable prosthetic materials such as those composed of lactic acid polymers or lactic and glycolic acid copolymers: however, the use of these absorbable prosthesis exposes the patient to a rapid and inevitable hernia recurrence. It is important to remember that prosthetic repair has been proven to have a significant less risk of recurrence than repair with direct sutures. Recently, new "biologic" prosthetic materials have been developed and proposed for the clinical use in infected fields. These materials can be called "remodeling" for the way by which they are replaced after their placement within the patient. The "remodeling" process is made possible through a process of incorporation, where a reproduction of a site-specific tissue similar to the original host tissue is created.

    The economic aspects of abdominal wall reconstruction are frequently overlooked, although understandings of the financial implications are essential in providing cost-efficient health care. Ventral hernia repairs are frequently performed surgical procedures with significant economic ramifications for employers, insurers, providers, and patients because of the volume of procedures, complication rates, the significant rate of recurrence, and escalating costs. Because biological mesh materials add significant expense to the costs of treating complex abdominal wall hernias, the role of such costly materials needs to be better defined to ensure the most cost-efficient and effective treatments for ventral abdominal wall hernias.

    Abdominal wall hernias are a common problem in the general population. A Western estimate reveals that the lifetime risk of developing a hernia is about 2%.1–3 As a result, hernia repairs likely comprise the most frequent general surgery operations. More than 20 million hernias are estimated to be repaired every year around the world.4 Numerous repair techniques have been described to date however tension-free mesh repairs are widely used today because of their low hernia recurrence rates. Nevertheless, there are some ongoing debates regarding the ideal approach (open or laparoscopic),5,6 the ideal anesthesia (general, local, or regional),7,8 and the ideal mesh (standard polypropylene or newer meshes).9,10 PMID:25216417

    Vesicouterine fistula (VUF) is a rare type of genitourinary fistula. Lower-segment cesarean section is the leading cause of VUF. Patients mostly present with the classical triad of menouria, amenorrhea, and urinary incontinence, with the history of a previous cesarean section. Conservative management with catheterization and open, laparoscopic, and robotic surgeries are the prescribed treatment options. We present the case of a 35-year-old woman who presented with cyclical menouria and urinary incontinence. After diagnosis of VUF by cystoscopy, the laparoscopic approach was chosen. During the procedure, we used anterior abdominal wall peritoneum and adjacent adipose tissue interposition for the first time, instead of omental interposition, because of the unavailability of omentum. The postoperative period was uneventful, and the procedure was successful. In conclusion, the laparoscopic approach is feasible and the anterior abdominal wall peritoneal flap can be used instead of omentum for tissue interposition when the omentum is not available.

    To compare the relative strength of incorporation and adhesion formation for mesh hernia repairs performed with Sepramesh (Genzyme Corp., Cambridge, Massachusetts) and Dualmesh (WL Gore and Assoc., Flagstaff, Arizona). A prospective randomized study was conducted using 30 New Zealand white rabbits, with 15 animals randomized to each limb. A standardized abdominal defect was created in each animal. The defect was then repaired using either Sepramesh or Dualmesh. Animals were sacrificed at 4 weeks. The area of adhesions was determined using digital analysis of inked specimens. Strength of incorporation was determined using an Instron Tensiometer. (Department of Clinical Research, D. D. Eisenhower Army Medical Center, Fort Gordon, GA 30905.) Sepramesh had a 30.6% stronger strength of incorporation compared with Dualmesh. (p = 0.011) The difference in area of adhesions was not statistically significant between the 2 products. The use of Sepramesh for abdominal hernia repairs provides a significantly stronger strength of incorporation without increasing the amount of adhesions as compared with Dualmesh.

    Reconstruction with reconstitution of the container function of the abdominal compartment is increasingly being performed in patients with massive ventral hernia previously deemed inoperable. This situation places patients at great risk of severe intra-abdominal hypertension and abdominal compartment syndrome if organ failure ensues. Intra-abdominal hypertension and especially abdominal compartment syndrome may be devastating systemic complications with systematic and progressive organ failure and death. We thus reviewed the pathophysiology and reported clinical experiences with abnormalities of intra-abdominal pressure in the context of abdominal wall reconstruction. Bibliographic databases (1950-2015), websites, textbooks, and the bibliographies of previously recovered articles for reports or data relating to intra-abdominal pressure, intra-abdominal hypertension, and the abdominal compartment syndrome in relation to ventral, incisional, or abdominal hernia repair or abdominal wall reconstruction. Surgeons should thus consider and carefully measure intra-abdominal pressure and its resultant effects on respiratory parameters and function during abdominal wall reconstruction. The intra-abdominal pressure post-operatively will be a result of the new intra-peritoneal volume and the abdominal wall compliance. Strategies surgeons may utilize to ameliorate intra-abdominal pressure rise after abdominal wall reconstruction including temporizing paralysis of the musculature either temporarily or semi-permanently, pre-operative progressive pneumoperitoneum, permanently removing visceral contents, or surgically releasing the musculature to increase the abdominal container volume. In patients without complicating shock and inflammation, and in whom the abdominal wall anatomy has been so functionally adapted to maximize compliance, intra-abdominal hypertension may be transient and tolerable. Intra-abdominal hypertension/abdominal compartment syndrome in the specific setting of

    Endometriosis of abdominal wall scar following operation on uterus and tubes is extremely rare. The late onset of symptoms after surgery is the usual cause of misdiagnosis. Scar endometriosis is a rare disease which is difficult to diagnose and should always be considered as a differential diagnosis of painful abdominal masses in women. The diagnosis is made only after excision and histopathology of the lesion. Preoperative differentials include hernia, lipoma, suture granuloma or abscess. Hence an awareness of the entity avoids delay in diagnosis, helps clinicians to a more tailored treatment and also avoids unnecessary referrals. We report a case of abdominal endometriosis. The definitive diagnosis of which was established by histopathological studies.

    2016-02-01

    Full Text Available Introduction: Although recently published guidelines recommend against the use of synthetic non-absorbable materials in cases of potentially contaminated or contaminated surgical fields due to the increased risk of infection [1, 2], the use of bio-prosthetic meshes for abdominal wall or ventral hernia repair is still controversially discussed in such cases. Bio-prosthetic meshes have been recommended due to less susceptibility for infection and the decreased risk of subsequent mesh explantation. The purpose of this review is to elucidate if there are any indications for the use of biological and biosynthetic meshes in incarcerated abdominal wall hernias based on the recently published literature.Methods: A literature search of the Medline database using the PubMed search engine, using the keywords returned 486 articles up to June 2015. The full text of 486 articles was assessed and 13 relevant papers were identified including 5 retrospective case cohort studies, 2 case controlled studies, 6 case series.Results: The results of Franklin et al [23, 24, 25] included the highest number of biological mesh repairs (Surgisis® by laparoscopic IPOM in infected fields which demonstrated a very low incidence of infection and recurrence (0,7% and 5,2%. Han et al [26] reported in his retrospective study the highest number of treated patients due to incarcerated hernias by open approach using acellular dermal matrix (ADM® with very low rate of infection as well as recurrences (1,6% and 15,9. Both studies achieved acceptable outcome in a follow up of at least 3,5 years compared to the use of synthetic mesh in this high-risk population [3]Conclusion:Currently there is a very limited evidence for the use of biological and biosynthetic meshes in strangulated hernias in either open or laparo-endoscopic repair. Finally, there is an urgent need to start with randomized controlled comparative trials as well as to support registries with data to achieve more

    defect involving the entire anterior abdominal wall of rats. METHODS:Twenty Wistar rats were allocated in 2 groups of 10 animals each. In the group 1 the defect was repaired with SIS and in the group2 it was repaired with polypropylene mesh. On the 30th post-operative day the animals were sacrificed for macroscopic , histological and tensiometric evaluation. RESULTS: Adhesions were present in the animals of both group , but in the polypropylene mesh group the intestinal adhesions were more frequent than in the SID group. The maximum tensile strength was greater in the polypropylene group, however is we consider the thickness of the implants, the tensile strength of submucosa was significantly greater. The mesothelium coverage and the collagen deposition was greater in the SID group. The foreign body reaction and the chronic inflammatory process was higher in the SID group. The percentage of mature collagen was significantly greater in the SIS group. CONCLUSION: We concluded that SIS can be an alternative to synthetic meshes when used to repair the defects of abdominal wall.

  6. Assessment of the abdominal wall function after pedicled TRAM flap surgery for breast reconstruction: Use of modified mesh repair for the donor defect

    2010-01-01

    Full Text Available Background: The pedicled TRAM flap has been a workhorse of autologous breast reconstruction for decades. However, there has been a rising concern about the abdominal wall donor site morbidity with the use of conventional TRAM flap. This has generally been cited as one of the main reasons for resorting to "abdominal wall friendly" techniques. This study has been undertaken to assess the abdominal wall function in patients with pedicled TRAM flap breast reconstruction. The entire width of the muscle and the overlying wide disk of anterior rectus sheath were harvested with the TRAM flap in all our patients and the anterior rectus sheath defect was repaired by a Proline mesh. Materials and Methods: Abdominal wall function was studied in 21 patients who underwent simultaneous primary unipedicled TRAM flap reconstruction after mastectomy for cancer. In all the patients, the abdominal wall defect was repaired using wide sheet of Proline mesh both as inlay and onlay. The assessment tools included straight and rotational curl ups and a subjective questionnaire. The abdominal wall was also examined for any asymmetry, bulge, or hernia. The minimal follow-up was 6 months postoperative. The objective results were compared with normal unoperated volunteers. Results and Conclusions: The harvesting the TRAM flap certainly results in changes to the anterior abdominal wall that can express themselves to a variable degree. A relatively high incidence of asymptomatic asymmetry of the abdomen was seen. There was total absence of hernia in our series even after a mean follow-up period of 15.5 months. A few patients were only able to partially initiate the sit up movement and suffered an important loss of strength. In most patients, synergists took over the functional movement but as the load increased, flexion and rotation performances decreased. The lack of correlation between exercise tests and the results of the questionnaire suggests that this statistically

    Full Text Available INTRODUCTION: Composite biomaterials designed for the repair of abdominal wall defects are composed of a mesh component and a laminar barrier in contact with the visceral peritoneum. This study assesses the behaviour of a new composite mesh by comparing it with two latest-generation composites currently used in clinical practice. METHODS: Defects (7x5cm created in the anterior abdominal wall of New Zealand White rabbits were repaired using a polypropylene mesh and the composites: Physiomesh(TM; Ventralight(TM and a new composite mesh with a three-dimensional macroporous polyester structure and an oxidized collagen/chitosan barrier. Animals were sacrificed on days 14 and 90 postimplant. Specimens were processed to determine host tissue incorporation, gene/protein expression of neo-collagens (RT-PCR/immunofluorescence, macrophage response (RAM-11-immunolabelling and biomechanical resistance. On postoperative days 7/14, each animal was examined laparoscopically to quantify adhesions between the visceral peritoneum and implant. RESULTS: The new composite mesh showed the lowest incidence of seroma in the short term. At each time point, the mesh surface covered with adhesions was greater in controls than composites. By day 14, the implants were fully infiltrated by a loose connective tissue that became denser over time. At 90 days, the peritoneal mesh surface was lined with a stable mesothelium. The new composite mesh induced more rapid tissue maturation than Physiomesh(TM, giving rise to a neoformed tissue containing more type I collagen. In Ventralight(TM the macrophage reaction was intense and significantly greater than the other composites at both follow-up times. Tensile strengths were similar for each biomaterial. CONCLUSIONS: All composites showed optimal peritoneal behaviour, inducing good peritoneal regeneration and scarce postoperative adhesion formation. A greater foreign body reaction was observed for Ventralight(TM. All composites induced

    Tissue reactions to titanium-nickelide and polypropylen and caprone implants used in surgical treatment of anterior aldomen wall hernias were studied in experiment. Digital density of leukocytes, fibroblasts, vessels, thickness of the capsule were studied. Pronounced inflammatory reaction was observed on day 3 which attenuated on day 14 in case of titanium nickelide and on day 30-60 in case of polypropylene and caprone. Fibroplastic processes start in the first group after 7 days while in the second group only after 30 days of the experiment. Thickness of the capsule around titanium-nickelide was 2-3 times less than around polypropylene and caprone. Thus, titanium-nickelide material is biologically more inert than caprone and polypropylen which are widely used in surgery of hernias.

    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.

    Funding received from Cousin Biotech, Wervicq Sud, France, and CR Bard Inc., Cranston, RI. The aim of this prospective randomized study was to determine the long-term recurrence and complication rates after small abdominal wall hernia repair with two different bilayer prostheses. Hernia repair using prosthetic mesh material has become the preferred method of repair, because the recurrence rates are much lower than with conventional repair techniques. The use of a hernia bilayer patch, composite expanded polytetrafluoroethylene (ePTFE)-polypropylene, with intraperitoneal placement behind the hernia defect, through a small incision, may be efficient, safe, and cost-effective. This study is a randomized, single-institution trial, including 83 selected consecutive patients with primary (umbilical, epigastric) or incisional anterior abdominal wall defects from 2 to 5 cm. Hernia repair was performed by direct local access in ambulatory surgery; the prosthesis used was a circular bilayer with an inner face in ePTFE to avoid bowel adhesion. One group was treated with a Ventralex® Hernia Patch (Bard USA). The second group was treated with a Cabs'Air® Composite (Cousin Biotech France), which was delivered with two to four fixation sutures and a balloon to properly deploy the mesh intraperitoneally. Patients' characteristics and operative and postoperative data were prospectively collected. The primary outcome was late recurrence. Secondary outcomes included, pain, discomfort and quality of life before and after (3 months) surgery using the SF-12 questionnaire, patient-surgeon satisfaction, and early and late complications. Among 98 patients, 83 were included in the study protocol between January 2007 and August 2011. The two groups were comparable according to pre- and intraoperative data. According to surgeon experience, placement of the Cabs'Air® device was significantly faster (P = 0.01) and easier. At 3 months, there was significantly less pain and less discomfort for

    The use of prosthetic mesh for the tension-free repair of incisional hernias has been shown to be more effective than primary suture repair. Unfortunately, prosthetic materials can be a suboptimal choice in a variety of clinical scenarios. In general, prosthetic materials should not be implanted into sites with known contamination or infection because they lack an endogenous vascular network and are thus incapable of clearing bacteria. This is of particular relevance to the repair of recurrent hernias, which are often refractory to repair because of indolent bacterial colonization that weakens the site and retards appropriate healing. Although fascia lata grafts and muscle flaps can be employed for tension-free hernia repairs, they carry the potential for significant donor site morbidity. Recently, a growing number of clinicians have used human acellular dermal matrix as a graft material for the tension-free repair of ventral hernias. This material has been shown to become revascularized in both animal and human subjects. Once repopulated with a vascular network, this graft material is theoretically capable of clearing bacteria, a property not found in prosthetic graft materials. Unlike autologous materials such as fascial grafts and muscle flaps, acellular dermal matrix can be used without subjecting the patient to additional morbidity in the form of donor site complications. This article presents a thorough review of the current literature, describing the properties of human acellular dermal matrix and discussing both animal and human studies of its clinical performance. In addition to the review of previously published clinical experiences, we discuss our own preliminary results with the use of acellular dermal matrix for ventral hernia repair in 46 patients.

    Objective: Uterus-to-abdominal-wall fistula is a very rare complication after uterine-incision delivery over the last decades. It can even lead to death. Mainly, the fistula occurs when big tension and critical infection exist within the incision of uterus and abdominal wall. Methods: The authors described the clinical presentation, pathology of uterus-to-abdominal-wall fistula, and reported their experience in 6 cases who underwent Z-plasty operation for this rare complication from January 1998 to January 2008. Results: All flaps survived completely and all the wounds in abdominal walls healed very well. The six cases were followed up for 1 to 5 years, and no fistula recurrence occurred. Conclusion: Z-plasty technique is a very simple and efficient approach to repair uterus to abdominal fistula after uterine-incision delivery.

    The reconstruction of abdominal wall defects remains a huge surgical challenge. Tension-free repair is proven to be superior to suture repair in abdominal wall reconstruction. Scaffolds are essential for tension-free repair. They are used to bridge a defect or reinforce the abdominal wall. A huge variety of scaffolds are now commercially available. Most of the synthetic scaffolds are composed of polypropylene. They provide strong tissue reinforcement, but cause a foreign body reaction, which can result in serious complications. Absorbable synthetic scaffolds, such as Dexon™ (polyglycolic acid) and Vicryl™ (polyglactin 910), are not suitable for abdominal wall reconstruction as they usually require subsequent surgeries to repair recurrent hernias. Composite scaffolds combine the strength of nonabsorbable synthetic scaffolds with the antiadhesive properties of the absorbable scaffold, but require long-term follow-up. Biological scaffolds, such as Permacol™, Surgisis(®) and Alloderm(®), are derived from acellular mammalian tissues. Non-cross-linked biological scaffolds show excellent biocompatibility and degrade slowly over time. However, remnant DNA has been found in several products and the degradation leads to recurrence. Randomized controlled trials with long-term follow-up studies are lacking for all of the available scaffolds, particularly those derived from animal tissue. This article provides an overview of the different types of scaffolds available, and presents the key clinical studies of the commercially available synthetic, composite and biological scaffolds for abdominal wall reconstruction.

    The literature dealing with abdominal wall surgery is often flawed due to lack of adherence to accepted reporting standards and statistical methodology. The EuraHS Working Group (European Registry of Abdominal Wall Hernias) organised a consensus meeting of surgical experts and researchers with an interest in abdominal wall surgery, including a statistician, the editors of the journal Hernia and scientists experienced in meta-analysis. Detailed discussions took place to identify the basic ground rules necessary to improve the quality of research reports related to abdominal wall reconstruction. A list of recommendations was formulated including more general issues on the scientific methodology and statistical approach. Standards and statements are available, each depending on the type of study that is being reported: the CONSORT statement for the Randomised Controlled Trials, the TREND statement for non randomised interventional studies, the STROBE statement for observational studies, the STARLITE statement for literature searches, the MOOSE statement for metaanalyses of observational studies and the PRISMA statement for systematic reviews and meta-analyses. A number of recommendations were made, including the use of previously published standard definitions and classifications relating to hernia variables and treatment; the use of the validated Clavien-Dindo classification to report complications in hernia surgery; the use of "time-to-event analysis" to report data on "freedom-of-recurrence" rather than the use of recurrence rates, because it is more sensitive and accounts for the patients that are lost to follow-up compared with other reporting methods. A set of recommendations for reporting outcome results of abdominal wall surgery was formulated as guidance for researchers. It is anticipated that the use of these recommendations will increase the quality and meaning of abdominal wall surgery research.

    The abdominal wall is an integral component of the chest wall. Defects in the ventral abdominal wall alter respiratory mechanics and can impair diaphragm function. Congenital abdominal wall defects also are associated with abnormalities in lung growth and development that lead to pulmonary hypoplasia, pulmonary hypertension, and alterations in thoracic cage formation. Although infants with ventral abdominal wall defects can experience life-threatening pulmonary complications, older children typically experience a more benign respiratory course. Studies of lung and chest wall function in older children and adolescents with congenital abdominal wall defects are few; such investigations could provide strategies for improved respiratory performance, avoidance of respiratory morbidity, and enhanced exercise ability for these children.

    Objectives: The components separation technique (CST) is a widely described abdominal wall reconstructive technique. There have, however, been no UK reports of its use, prompting the present review. Methods: Between 2008 and 2012, 13 patients who underwent this procedure by a single plastic surgeon (C.M.M.) were retrospectively evaluated. The indications, operative details, and clinical outcomes were recorded. Results: There were 7 women and 6 men in the series with a mean age of 53 years (range: 30-80). Patients were referred from a variety of specialties, often as a last resort. The commonest indication for CST was herniation following abdominal surgery. All operations except 1 were jointly performed with general surgeons (for bowel resection, stoma reversal, and hernia dissection). The operations lasted a mean of 5 hours (range: 3-8 hours). There were no major intra- and postoperative problems, except in 1 patient who developed intra-abdominal compartment syndrome, secondary to massive hemorrhage. All patients were satisfied with the cosmetic improvement in their abdominal contours. None of the patients have developed a clinical recurrence after a mean follow-up of 16 months (range: 3-38 months). Conclusions: The components separation technique is an effective method of treating large recalcitrant hernias but appears to be underutilized in the United Kingdom. The management of large abdominal wall defects requires a multidisciplinary approach, with input across a variety of specialities. Liaison with plastic surgery teams should be encouraged at an early stage and the CST should be more widely considered when presented with seemingly intractable abdominal wall defects. PMID:24058718

    Full Text Available Abstract Introduction Traumatic hernia of the abdominal wall is a rare entity. A large proportion of reported cases are in children with a particular type of injury, i.e. from a handlebar injury. In adults, the presentation can vary substantially and the diagnosis is difficult. We present two cases in adults, with widely varying presentations and management. Case presentations A 40-year-old woman from rural north India presented with a low-velocity blunt injury to the lower abdomen. She was attacked by a bull. She had a clinically evident abdominal fascial disruption with intact skin, and was hemodynamically stable. An emergency mesh repair of the defect was performed, and she recovered well. A 38-year-old man from rural north India presented with blunt trauma to the abdomen following a motor vehicle accident. He was stable, with a central abdominal parietal wall swelling and bruising. A computed tomography scan revealed herniation of bowel loops in the area with minor intra-abdominal injuries. A laparotomy, resection-anastomosis of the ischemic bowel, and primary repair of the defect was performed and he recovered well. Conclusion Following blunt abdominal trauma, particularly high-velocity injuries, a high index of suspicion must be reserved for parietal wall swellings, as missed hernias in this setting have a high risk of strangulation. Computed tomography is the best aid to diagnosis. Management of each case needs to be individualized.

    Abdominal wall hernias are a common condition. However, they may develop acute complications and require surgical correction in most cases. Hence, the correct radiological examination is requisite for an accurate diagnosis. A multi-detector row CT (MDCT) provides an accurate identification of the anatomy of the abdominal wall, precise hernia type, and helps in the detection of early signs of complication. We report various imaging features of abdominal wall hernias via a MDCT.

    To evaluate the imaging findings of abdominal wall endometriosis. In seven of 17 patients with surgically proven endometriosis of the abdominal wall, we retrospectively reviewed the findings of radiologic studies such as abdominal US (n=3), CT (n=4), and MRI (n=1). One patient under went more than one type of imaging, apparently. The surgical history of the seven, and their symptoms and preoperative diagnosis were reviewed, and the size, location, margin and nature of the mass, and the contrast enhancement patterns observed at radiologic studies, were assessed. The chief symptoms were palpable abdominal wall mass (n=5) and lower abdominal pain (n=2) around a surgical scar. Previous surgery included cesarean section (n=5), cesarean section with oophorectomy (n=1) and appendectomy (n=1). Masses were located in the subcutaneous fat layer (n=5) or rectus abdominis muscle (n=2), and their maximum diameter was 2.6 cm. Imaging findings, which correlated closely with the pathologic findings, included a well (n=5) or poorly marginated (n=2) solid mass, with a focal cystic area apparent in two cases. Although imaging findings of abdominal wall endometriosis may not be specific for diagnosis, the presence of a solid abdominal mass in female patients of reproductive age with a history of surgery is a diagnostic pointer.

    Hernia is due to abdominal wall weakening. This allows the contents of the abdomen to protrude from normal boundaries. Hernias are repaired by implanting a sterile surgical mesh to strengthen the weakened abdominal wall. Aim of this study is to compare the results obtained by bard Composix® L/P mesh or Dualmesh Plus Gore® implanting. The mesh has various beneficial characteristics. It is a reinforcing material for the abdominal wall, even when in the direct contact with the intestinal tract does not cause adhsion problems. The use of biocompatible materials is necessary in laparoscopic hernia repair. e-PTFE prosthesis and Dual Mesh® were the first to be used for laparoscopic treatment of the abdominal wall defects. These prosthesis are the result of many improvements, actually they are 1-mm thick and the two surfaces have different characteristics. Compound meshes are composed by e-PTFE and polypropylene with different percentage of the two materials and methods of interactions. The incidence of early complications were poor in relation to both types of implants, only seroma cases e-PTFE treated showed a prevalence of complication, in agreement with literature. About relapses in our experience we found that e-PTFE cases were predominantly. Dual Mesh® has better adaptability than Bard Composix®, which allows easier placement of the prosthesis as well as a better adaptation to the wall surface. The Bard Composix®, thanks to rigidity due to the polypropylene component has better handling than the Dual Mesh®, as it promotes a rapid and easy deployment of the prosthesis inside the abdominal cavity, favoring its positioning. The use of both prosthesis depends also on the experience specific to each operator, moreover, a rigorous surgical technique remains fundamental for the application of the mesh used.

    The management of primary and recurrent giant incisional hernias remains a complex and frustrating challenge even with multiple alloplastic and autogenous closure options. The purpose of this study was to develop a reconstructive technique of restoring abdominal wall integrity to a subcategory of patients, who have failed initial hernia therapy, by performing superior and lateral myofascial release. Over a 1.5-year period, 10 patients with previously unsuccessful treatment of abdominal wall hernias, using either primary repair or placement of synthetic material, were studied. The patients had either recurrence of the hernia or complications such as infections requiring removal of synthetic material. The hernias were not able to be treated with standard primary closure techniques or synthetic material. The average defect size was 19 x 9 cm. Each patient underwent wide lysis of bowel adhesions releasing the posterior abdominal wall fascia to the posterior axillary line, subcutaneous release of the anterior abdominal wall fascia to a similar level, and complete removal of any synthetic material (if present). The abdominal domain was reestablished by releasing the laterally retracted abdominal wall. The amount of available abdominal wall tissue was increased by wide release of the cephalic abdominal wall fascia overlying the costal margin and the external oblique fascia and muscle laterally. If needed, partial thickness of the internal oblique muscle and its anterior fascia were also released laterally to perform a tension-free primary closure of the defect. All repairs were closed with satisfactory functional and aesthetic results. All alloplastic material was removed. Fascial release was limited so as to close only the hernia defect without tension. No significant release of the rectus sheath and muscle was needed. Good, dynamic muscle function was noted postoperatively. All repairs have remained intact, and no further abdominal wall hernias have been noted on follow-up.

    Full Text Available Background. Desmoids are benign tumors, with local invasive features and no metastatic potential, which have rarely been described to be pregnancy associated. Case. We described the rapid growth of an anterior abdominal wall mass in a 40-year-old pregnant woman. Due to its close proximity to the enlarged uterus, it was misdiagnosed to be a uterine leiomyoma by ultrasound examination. Final tissue diagnosis and radical resection were done at the time of abdominal delivery. Conclusion. Due to the diagnostic limitations of imaging techniques, desmoids should always be considered when the following manifestations are observed in combination: progressive growth of a solitary abdominal wall mass during pregnancy and well-delineated smooth tumor margins demonstrated by imaging techniques. This case emphasizes the importance of entertaining uncommon medical conditions in the differential diagnosis of seemingly common clinical manifestations.

    Computed tomography is an accurate method of identifying the various types of abdominal wall hernias, especially if they are clinically occult, and of distinguishing them from other diseases such as hematomas, abscesses and neoplasia. In this study we examined the CT images of 94 patients affected by abdominal wall hernias observed over a period of 6 years. Computed tomography clearly demonstrates the anatomical site of the hernial sac, the content and any occlusive bowel complications due to incarceration or strangulation. Clinical diagnosis of external hernias is particularly difficult in obese patients or in those with laparotic scars. In these cases abdominal imaging is essential for a correct preoperative diagnosis and to determine the most effective treatment. (orig.)

    Full Text Available Abdominal wall endometrioma is a condition rarely seen by surgeons. It represents a diagnostic challenge due to its similarity with other tumors. This entity occurs in fertile women and often appears two to five years after gynecological and obstetric surgical procedures. It must be considered when dealing with a cyclically painful nodule located in a laparotomy scar. The diagnosis is established by histological examination; most imaging tests determine the characteristics of the lesion, concomitant lesions and the intra-abdominal origin or location in the abdominal wall. The cases of two patients treated at the General Surgery Department of the María Eugenia González Comprehensive Diagnostic Center in the Capital District, Venezuela, are presented. Wide excision of the tissue and histological examination were performed, confirming the diagnosis. The postoperative course was uneventful. This case is presented given the rarity of this condition.

  18. Blunt Abdominal Wall Disruption by Seatbelt Injury; A Case Report and Review of the Literature

    Full Text Available With the introduction of the use of seatbelts in cars, mortality following motor vehicle crashes has decreased significantly. However, two patterns of injuries, the ‘seatbelt sign’ and ‘seatbelt syndrome’ have emerged. Injuries may consist of traumatic abdominal wall disruption. We present two cases of severe abdominal wall disruption caused by a seatbelt injury and treated with primary repair. A review of the literature is provided. Two patients were brought in after a high velocity Motor Vehicle Collision. Both presented with an acute abdomen and a seatbelt sign upon which the decision was made to perform emergency laparotomies. Both patients had an abdominal wall disruption along the seatbelt sign. These disruptions were primarily closed and during six months of follow-up no complications occurred. A disruption of the abdominal wall is a rare complication. However, it is a diagnosis that may not be missed as patients have a higher risk of morbidity and mortality. CT-scanning is an accurate method to detect disruptions. Closure of blunt traumatic abdominal wall disruption can be done primarily with sutures or addition of a mesh. In both cases of the severe abdominal wall disruption, primary repair without mesh in the acute phase was successful. When a laparotomy is not indicated, the abdominal wall must be assessed for disruption. If there is a disruption primary repair is a good option.

    Full Text Available Introduction. Rupture of an abdominal aortic aneurysm (AAA is a potentially lethal state. Only half of patients with ruptured AAA reach the hospital alive. The alternative for open reconstruction of this condition is endovascular repair (EVAR. We presented a successful endovascular reapir of ruptured AAA in a patient with a number of comorbidities. Case report. A 60-year-old man was admitted to our institution due to diffuse abdominal pain with flatulence and belching. Initial abdominal ultrasonography showed an AAA that was confirmed on multislice computed tomography scan angiography which revealed a large retroperitoneal haematoma. Because of patient’s comorbidites (previous surgery of laryngeal carcinoma and one-third laryngeal stenosis, arterial hypertension and cardiomyopathy with left ventricle ejection fraction of 30%, stenosis of the right internal carotid artery of 80% it was decided that endovascular repair of ruptured AAA in local anaesthesia and analgosedation would be treatment of choice. Endovascular grafting was achieved with aorto-bi-iliac bifurcated excluder endoprosthesis with complete exclusion of the aneurysmal sac, without further enlargment of haemathoma and no contrast leakage. The postoperative course of the patient was eventless, without complications. On recall examination 3 months after, the state of the patient was well. Conclusion. The alternative for open reconstruction of ruptured AAA in haemodynamically stable patients with suitable anatomy and comorbidities could be emergency EVAR in local anesthesia. This technique could provide greater chances for survival with lower intraoperative and postoperative morbidity and mortality, as shown in the presented patient.

    AlloDerm (decellularized human cadaveric dermis) is increasingly being used for tissue reconstruction and hernia repairs. This article presents the results of AlloDerm use in treating abdominal wall hernias by analyzing all patients who underwent repair with AlloDerm at our institution. A series of 70 consecutive patients starting in October 2003 with abdominal wall hernia repair using AlloDerm was studied. This study began as a retrospective chart review, which included subsequent postoperative follow-up. SPSS version 11.5 was used for statistical analysis, and parametric tests were conducted. Various technical variables (type of AlloDerm placement, mesh-suture technique, suture type) and nontechnical variables (steroids use, obesity, smoking status, diabetes, prior surgeries, number of comorbidities) were evaluated. Of 70 study patients, 31 were men and 39 were women, with a mean age of 58 (range 25-88) years. Fifty-six patients (80%) had no complications, whereas 14 (20%) suffered one or more complications. Of those patients with complications, there was one rejection, two infections, and 14 hernia recurrences. The overall complication rate was 24%. Of patients with hernia recurrences, one had the initial repair with AlloDerm implant of 1.8-mm thickness (ultrathick). The 14 patients with recurrences include three who had a prior AlloDerm repair with ultrathick implant. Two of these three patients reported abdominal wall protrusion, and one had a recurrence between two pieces of AlloDerm used in the initial repair. Of these 14 patients, nine had subsequent repair of their recurrence with synthetic mesh, and four had subsequent repair with AlloDerm with satisfactory outcomes; one patient was yet to have a repair at the time of this paper. Recurrence rates with ultrathick and thick AlloDerm were 23% and 6%, respectively. None of the patients who were on steroid therapy had complications. Mesh-suture technique had no effect on recurrence. Type of placement was

    MMP8 e MMP13 em relação à Surgisis®.BACKGROUND: In general surgery, the repair of abdominal wall hernias has a prominent place, and the indications and uses of meshes have increased due to better results. AIM: To compare the repair of induced abdominal wall defects with Parietex® and Surgisis® meshes, in direct contact with abdominal viscera (intraperitoneal mesh. METHOD: For the experiments, were used 16 female young adult rabbits. Two full thickness triangular defects of 2 cm base by 2.5 cm high were created, lateral to the linea alba, one at each side. They were repaired with rectangular meshes of 3 cm base by 3.5 cm high, on the right side with Parietex® mesh (polyester/collagen-polyethylenglycol-glycerol, and on the left side with Surgisis® mesh (lyophilized porcine small bowel submucosa. The evaluation included clinical-surgical findings as well as histological and immunohistochemical parameters. Eight rabbits were subjected to euthanasia after 30 days, and the eight after 60 days. RESULTS: Both meshes induced skin erosions, despite the varying levels of mesh undermining evaluated, no incisional hernia occurred. There were peritoneal adhesions to the surface of both types of meshes after 30 days and in a lower extent and intensity after 60 days. Meshes' shrinking correspond to 1/3 of the original size and Parietex® caused less inflammatory process at the histologic evaluation. Deposition of collagen type I presented no significant difference between the meshes, but deposition of collagen type III was more intense after 60 days, in both groups. Regarding collagen's rearrangement, the production of MMP8 was higher on Parietex® after 30 days, and MMP13 enzyme was increased after 60 days, in both meshes (significant only for Parietex®. CONCLUSION: Both meshes were efficient in the correction of abdominal wall defects, and with similar results, but Parietex® presented less inflammatory process and greater amount of matrix-metalloproteinases MMP8 and MMP13

    Full Text Available Introduction. Reconstruction of a full thickness abdominal wall defect is a demanding procedure for general and also for plastic surgeons, requiring vigorous planning and reconstruction of three layers. Case Outline. We present a case of a 70-year-old patient with a huge abdominal wall tumor with 40 years evolution. Surgery was performed under general anesthesia. Full thickness abdominal defect appeared after the tumor resection. Reconstruction followed in the same act. The defect was reconstructed using a combination of techniques, including omental flap, fascia lata graft, local skin flaps and skin grafts. After surgery no major complications were noted, only a partial skin flap loss, which was repaired using partial thickness skin grafts. The final result was described by the patient as very good, without hernia formation. Conclusion. Omenthoplasty, abdominal wall reconstruction in combination with free fascia lata graft and skin grafts can be one of good options for the reconstruction of full thickness abdominal wall defects.

    There is an increasing interest in patient-reported outcome measurement to evaluate hernia operations. Several hernia-specific quality of life (QoL) scales have been proposed, but none are constructed for preoperative assessment. The European Registry for Abdominal Wall Hernias (EuraHS) proposed the short, 9-question EuraHS-QoL instrument for assessment pre- and postoperatively. The EuraHS-QoL was evaluated in a prospective, multicenter validation study alongside the Visual Analogue Scale, Verbal Rating Scale, and Carolina Comfort Scale (https://clinicaltrials.gov; NCT01936584). We included 101 patients undergoing unilateral laparoscopic inguinal hernia repair with ProGrip laparoscopic, self-fixating mesh. Clinical follow-up at 12 months was 87% complete. The EuraHS-QoL score shows good internal consistency (Cronbach's α ≥ .90), good test-retest reliability (Spearman correlation coefficient r ≥ 0.72), and high correlation for pain with the Visual Analogue Scale, the Verbal Rating Scale, the Carolina Comfort Scale pain scale (r between 0.64 and 0.86), and for restriction of activity with the Carolina Comfort Scale movement scale (r between 0.65 and 0.79). Our results show significant improvement in quality of life at 3 weeks compared with preoperative and further significant improvement at 12 months (P 75%) or with a 95%) in the majority of the patients. The EuraHS-QoL instrument is a short and valid patient-reported outcome measurement following groin hernia repair. Laparoscopic inguinal hernia repair with ProGrip laparoscopic, self-fixating mesh results in a favorable outcome and significant improvement of quality of life compared with the preoperative assessment.

    Abdominal wall or parastomal hernias following major genitourinary or abdominal surgery are a significant surgical problem. Open surgical repair is difficult because of adhesion formation and poor definition of the hernia fascial edges. Laparoscopic intervention has allowed effective correction of these abdominal wall hernias. From November 1997 to June 2000, 14 male and 3 female patients underwent laparoscopic abdominal wall herniorrhaphy at our institution. Of these, 13 patients received incisional and 4 parastomal hernia repair. All hernia defects were repaired using a measured piece of Gore-Tex DualMesh. A retrospective review of each patient's history and operative characteristics was undertaken. All repairs were successful. No patient required conversion to an open procedure, and there were no intraoperative complications. The average operative time was 4 (range 2.5-6.5) and 4.3 (range 3.75-5.5) hours in the incisional and parastomal group, respectively. The average hospital stay was 4.9 days (range 2-12) for the incisional group and 3.8 (range 3-4) days for the parastomal group. To date, two patients experienced a recurrence of incisional hernias, at 5 and 8 months postoperatively. No recurrences have developed in the parastomal hernia repairs at 2 to 33 months. Laparoscopic repair of abdominal wall incisional or parastomal hernias provides an excellent anatomic correction of such defects. Adhesions are lysed under magnified laparoscopic vision, and the true limits of the fascial defects are clearly identified. The DualMesh is easy to work with and has yielded excellent results. A comparison with open repair with respect to perioperative factors and long-term success is currently under way.

    An improved technique for performing laparoscopic repair of an abdominal hernia is described herein. To ensure a successful repair, it is most important that adequate tension of the expanded-polytetrafluoroethylene (e-PTFE) patch be achieved, and that the defect be completely covered and securely stapled. Our technique involves tacking the four corners of the patch to the abdominal wall with a 2-0 nylon suture using a straight needle, then stapling it to the anterior abdominal wall over the defect with a laparoscopic stapler. We believe that this technique is a safe and reliable method which will prove useful for laparoscopic surgery.

    Endometriosis is the presence of endometrial glands and stroma outside the uterus. Spontaneous abdominal wall endometriosis (AWE) is any ectopic endometrium found superficial to the peritoneum without the presence of any previous scar. Rarely, endometriosis represents a disease of specific interest to the general surgeon, on account of its extrapelvic localisations. We describe a case with spontaneous AWE presenting as a painful mass with cyclic symptoms. A 28-year-old woman presented to the day-surgery division of our department, suffering from a painful mass in the left lower abdominal quadrant. A mobile mass of 5 x 4 cm was identified. The initial diagnosis was lipoma and excision was planned. During the operation two masses were spotted, very close to one another, and were excised within healthy limits. Pathology revealed endometrial glands surrounded by a disintegrating mantle of endometrial stroma and fibrous scar tissue in which there was a scattering of leucocytes. The woman had no scars. She was discharged from hospital after 2 hours. Two years after the excision she is free of disease and no recurrence has been observed. Spontaneous AWE is rare, accounting for 20% of all AWEs. The triad ; mass, pain and cyclic symptomatology helps in the diagnosis, but unfortunately it is not present in all cases. Spontaneous endometriomas are usually diagnosed by pathology and the treatment of choice is surgical excision.

    Conclusions: Postoperative complication rates after 18 months were low, and most surgical complications were managed nonoperatively on an outpatient basis without mesh removal. To our knowledge, this is the only series to report on a long-lasting, transitory SBS for abdominal wall repair and reinforcement. Procedure-specific outcome studies are warranted to delineate optimal patient selection and define potential device characteristic advantages.

    Chronic abdominal pain is a common clinical problem in primary care, and is usually referred to gastroenterologists or general surgeons. Although up to 20% of cases of idiopathic abdominal pain arise in structures of the abdominal wall, this is frequently overlooked as a possible cause. It includes pain arising from structures of the abdominal wall including skin, parietal peritoneum, cellular subcutaneous tissue, aponeuroses, abdominal muscles and somatosensorial innervation from lower dorsal roots. The diagnosis is based on anamnesis and physical examination. Carnett's sign is a simple maneuver that discriminates between parietal and visceral pain. Management with topical anesthesia is effective in a majority of patients and can help to confirm the diagnosis.

    matrix in the reconstruction of abdominal wall defects in rabbits, and to investigate the application feasibility of xeno-transplantation of acellular dermal matrix. Methods The porcine acellular dermal matrix was prepared from a health white pig. Twenty-six Japanese white rabbits (weighing 2.2-2.3 kg, female or male) were randomly assigned to 2 groups: the control group (n=6) and the experimental group (?=20). In the control group, the full-thickness abdominal wall defect of 5.0 cm × 0.5 cm was made, and the defect was sutured directly, in the experimental group, the full-thickness abdominal wall defect of 5.0 cm × 2.5 cm was made, and the defect was repaired with porcine acellular dermal matrix patch at the same size as the defect. At 5 weeks after surgery, the incidence of hernia and the intra-abdominal adhesions were observed and the wound breaking strength was compared between the patch-fascia interface and the fascia-fascia interface. The graft vascularization was evaluated through histological analysis at 6 months after surgery in the experimental group. Results No hernia occurred in all rabbits of 2 groups. At 5 weeks after surgery, healing was observed between patch and the muscularfascia; the vascularization was seen in the porcine acellular dermal matrix patch. There was no significant difference in the adhesion grade (Z= -0.798, P=0.425) between the experimental group (grade 2 in 1 rabbit, grade 1 in 5, and grade 0 in 12) and the control group (grade 1 in 1 and grade 0 in 5). No significant difference was found (t= -0.410, P=0.683) in the breaking strength between the patch-fascia interface in the experimental group [(13.0 ± 5.5) N] and the fascia-fascia interface in control group [(13.6 ± 4.0) N]. In the experimental group, the small vessels and the infiltration of inflammatory cells were observed in the porcine acellular dermal matrix patch after 5 weeks through histological observations. The junctions of the patch-fascia interface healed with fibrous

    Full Text Available PURPOSE: Biomaterials may be used as treatment of great abdominal wall defects to avoid tension during repair. In the present research we intended to investigate incorporation type by host tissue of membranes of microbial cellulose (MC, produced by the bacteria Zoogloea sp., and of polytetrafluoroethylene (ePTFE in abdominal wall defects of rats. METHODS: Sixty male rats Wistar, anesthetized by ketamine (5mg/100g and xylazine (2mg/100g, were submitted to a rectangular excision (2x3cm of the abdominal wall, including fascia, muscles and peritoneum and further treated with implants of microbial cellulose (MC Group - 30 animals or expanded polytetrafluoroethylene ( ePTFE Group- 30 animals. Each group was subdivided in 14th DPO, 28th DPO and 60th DPO Subgroups. RESULTS: Incorporation of biomaterials was observed by wrapping and infiltration by host tissue. It has been found that wrapping associated to infiltration of host connective tissue in implants of ePTFE were present in 100% of the observed samples, and this may be responsible for increase resistance to traction. Inversely, wrapping without host tissue infiltration was seen in 100% of examined specimens of MC implants. CONCLUSION: Wrapping and host tissue infiltration is seen only in ePTFE implants.OBJETIVO: Biomateriais podem ser usados como tratamento de grandes defeitos da parede abdominal para evitar tensão durante reparo.

    A variety of laparoscopic procedures for the repair of abdominal wall hernias have been described. The repair described in this paper represents a modification and improvement of one approach. Our technique employs an Origin Tacker (Origin Medsystems, Inc, Menlo Park, CA) and a Gore suture passer (W. L. Gore, Flagstaff, AZ) to secure an expanded polytetrafluoroethylene (ePTFE) patch, (DualMesh, W. L. Gore, Flagstaff, AZ) to the anterior abdominal wall. This approach simplifies the repair by minimizing the number of steps required to secure the ePTFE graft to the anterior abdominal. We have found this to be a safe and reliable technique that may be used in the laparoscopic repair of ventral, umbilical, or inguinal hernias.

    Full Text Available In patients with omphalocele, several different techniques are performed for repair of the abdominal wall defect. We present the case of a staged abdominal closure of a giant incisional hernia after repair of a ruptured omphalocele. At birth, skin flap coverage associated with silo formation occurred, but the abdominal wall defect remained, resulting in a giant abdominal hernia. To expand the layers of the abdominal wall, tissue expanders were placed between the bilateral internal oblique and transverses abdominis muscles. Postoperatively, a modified components separation technique was performed. The abdominal wall was closed in the midline. Upon closure of the skin in the midline, bilateral relaxing incisions were performed, covering the remaining defect with artificial dermis. At the age of one year and 7 months, the patient had no recurrent incisional hernia nor any wound complications.

    Full Text Available Synovial sarcoma (SS is a malignant mesenchymal neoplasm which commonly occurs in the extremities in close association with tendon sheaths, bursae, joint capsules, and fascial structures. Rarely, SS may be present in unexpected location such as the abdominal wall. Surgical resection with wide margins is the initial standard treatment; however, a multimodal approach including radiotherapy and chemotherapy is often favored. Here, we present a case of SS of the anterior abdominal wall in a 14-year-old patient with a right upper abdominal lump. He underwent wide surgical excision and has received adjuvant chemotherapy. He is doing well on follow-up of six months.

    Full Text Available Traumatic abdominal wall hernia (TAWH is rare despite the high prevalence of blunt abdominal trauma. Bullhorn hernia occurs as a result of a direct blow to the abdominal wall by the horn of a bull, which disrupts the muscles and fascia and leads to hernia formation. We report a rare case of bullhorn TAWH in a 70-year-old patient who presented with swelling at the left lumbar region. The patient was managed by immediate surgical intervention. A surgeon must have high index of suspicion for the diagnosis of this condition as missed hernias in this setting pose a high risk of strangulation and gangrene.

    Abdominal aortic aneurysm (AAA) is a relatively common pathology among the elderly. More people above the age of 80 will have to undergo treatment of an AAA in the future. This review aims to summarize the literature focusing on endovascular repair of AAA in the geriatric population. A systematic review of the literature was performed, including results from endovascular abdominal aortic aneurysm repair (EVAR) registries and studies comparing open repair and EVAR in those above the age of 80. A total of 15 studies were identified. EVAR in this population is efficient with a success rate exceeding 90% in all cases, and safe, with early mortality and morbidity being superior among patients undergoing EVAR against open repair. Late survival can be as high as 95% after 5 years. Aneurysm-related death over long-term follow-up was low after EVAR, ranging from 0 to 3.4%. Endovascular repair can be offered safely in the geriatric population and seems to compare favourably with open repair in all studies in the literature to date.

    Purpose: The treatment of ventral hernias (VH) has been a challenging problem for medical care. Repair of these hernias is fraught with failure; recurrence rates ranging from 24% to 43% have been reported, even with the use of biocompatible mesh. Currently, computed tomography (CT) is used to guide intervention through expert, but qualitative, clinical judgments, notably, quantitative metrics based on image-processing are not used. The authors propose that image segmentation methods to capture the three-dimensional structure of the abdominal wall and its abnormalities will provide a foundation on which to measure geometric properties of hernias and surrounding tissues and, therefore, to optimize intervention.Methods: In this study with 20 clinically acquired CT scans on postoperative patients, the authors demonstrated a novel approach to geometric classification of the abdominal. The authors’ approach uses a texture analysis based on Gabor filters to extract feature vectors and follows a fuzzy c-means clustering method to estimate voxelwise probability memberships for eight clusters. The memberships estimated from the texture analysis are helpful to identify anatomical structures with inhomogeneous intensities. The membership was used to guide the level set evolution, as well as to derive an initial start close to the abdominal wall.Results: Segmentation results on abdominal walls were both quantitatively and qualitatively validated with surface errors based on manually labeled ground truth. Using texture, mean surface errors for the outer surface of the abdominal wall were less than 2 mm, with 91% of the outer surface less than 5 mm away from the manual tracings; errors were significantly greater (2–5 mm) for methods that did not use the texture.Conclusions: The authors’ approach establishes a baseline for characterizing the abdominal wall for improving VH care. Inherent texture patterns in CT scans are helpful to the tissue classification, and texture

    The management of unexpected intra-abdominal malignancy, discovered at laparotomy for elective treatment of an abdominal aortic aneurysm (AAA), is controversial. It is still unclear whether both conditions should be treated simultaneously or a staged approach is to be preferred. To contribute in improving treatment guidelines, we retrospectively reviewed the records of patients undergoing laparotomy for elective AAA repair. From January 1994 to March 2003, 253 patients underwent elective, trans-peritoneal repair of an AAA. In four patients (1.6%), an associated, unexpected neoplasm was detected at abdominal exploration, consisting of one renal, one gastric, one ileal carcinoid, and one ascending colon tumor. All of them were treated at the same operation, after aortic repair and careful isolation of the prosthetic graft. The whole series' operative mortality was 3.6%. None of the patients simultaneously treated for AAA and tumor resection died in the postoperative period. No graft-related infections were observed. Simultaneous treatment of AAA and tumor did not prolong significantly the mean length of stay in the hospital, compared to standard treatment of AAA alone. Except for malignancies of organs requiring major surgical resections, simultaneous AAA repair and resection of an associated, unexpected abdominal neoplasm can be safely performed, in most of the patients, sparing the need for a second procedure. Endovascular grafting of the AAA can be a valuable tool in simplifying simultaneous treatment, or in staging the procedures with a very short delay.

    Mesh infection after abdominal hernia repair is a devastating complication that affects general and plastic surgeons alike. The purpose of this study was 3-fold: (1) to determine current evidence for treatment of infected abdominal wall mesh via systematic review of literature, (2) to analyze our single-institution experience with treatment of infected mesh patients, and (3) to establish a framework for how to approach this complex clinical problem. Literature search was performed using the Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines, followed by single-institution retrospective analysis of infected mesh patients. A total of 3565 abstracts and 92 full-text articles were reviewed. For qualitative and quantitative assessment, articles were subdivided on the basis of treatment approach: "conservative management," "excision of mesh with primary closure," "single-stage reconstruction," "immediate staged repair," and "repair in contaminated field." Evidence for each treatment approach is presented. At our institution, most patients (40/43) were treated by excision of infected mesh and single-stage reconstruction with biologic mesh. When the mesh was placed in a retrorectus or underlay fashion, 21.4% rate of hernia recurrence was achieved. Bridged repairs were highly prone to recurrence (88.9%; P = 0.001), but the bridging biologic mesh seemed to maintain domain and potentially contribute to a more effective repair in the future. Of the patients who underwent additional ("secondary") repairs after recurrence, 75% were eventually able to achieve "hernia-free" state. This study reviews the literature and our single-institution experience regarding treatment of infected abdominal wall mesh. Framework is developed for how to approach this complex clinical problem.

    An abdominal aortic aneurysm is a pathological dilation of the abdominal aorta, which carries a high mortality rate if ruptured. The most commonly used surrogate marker of rupture risk is the maximal transverse diameter of the aneurysm. More recent studies suggest that wall stress from models of patient-specific aneurysm geometries extracted, for instance, from computed tomography images may be a more accurate predictor of rupture risk and an important factor in AAA size progression. However, quantification of wall stress is typically computationally intensive and time-consuming, mainly due to the nonlinear mechanical behavior of the abdominal aortic aneurysm walls. These difficulties have limited the potential of computational models in clinical practice. To facilitate computation of wall stresses, we propose to use a linear approach that ensures equilibrium of wall stresses in the aneurysms. This proposed linear model approach is easy to implement and eliminates the burden of nonlinear computations. To assess the accuracy of our proposed approach to compute wall stresses, results from idealized and patient-specific model simulations were compared to those obtained using conventional approaches and to those of a hypothetical, reference abdominal aortic aneurysm model. For the reference model, wall mechanical properties and the initial unloaded and unstressed configuration were assumed to be known, and the resulting wall stresses were used as reference for comparison. Our proposed linear approach accurately approximates wall stresses for varying model geometries and wall material properties. Our findings suggest that the proposed linear approach could be used as an effective, efficient, easy-to-use clinical tool to estimate patient-specific wall stresses.

Methods Abdominal wall defect was repaired using engineered scaffold in rat modes. The rats were sacrificed after 4 weeks and the sample tissues were analyzed by gross observation, histological method and mechanical testing. Results All rats had no abdominal dehiscence or hernia. The engineered scaffold caused slight adhesion with organs. HE and Masson staining proved the junction between SIS and surrounding tissue had more new vessels. The muscle grew into the engineered scaffold. The mechanical strength of the engineered scaffold was much more than the abdominal wall muscles, which could provide sufficient mechanical strength. Conclusions Engineered scaffold repairing abdominal wall defect is a feasible and effective method.

    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.

    Outcomes after ventral incisional hernia (VIH) repair are measured by recurrence rate and subjective measures. No objective metrics evaluate functional outcomes after abdominal wall reconstruction. This study aimed to develop testing of abdominal wall strength (AWS) that could be validated as a useful metric. Data were prospectively collected during 9 months from 35 patients. A total of 10 patients were evaluated before and after VIH repair, for a total of 45 encounters. The patients were tested simultaneously or in succession by two of three examiners. Data were collected for three tests: double leg lowering (DLL), trunk raising (TR), and supine reaching (SR). Raw data were compared and tested for validity, and continuous data were transformed to categorical data. Agreement was measured using the intraclass correlation coefficient (ICC) for DLL and using kappa for the ordinal measures. Simultaneous testing yielded the following interobserver reliability: DLL (0.96 and 0.87), TR (1.00 and 0.95), and SR (0.76). Reproducibility was assessed by consecutive tests, with correlation as follows: DLL (0.81), TR (0.81), and RCH (0.21). Due to poor interobserver reliability for the SR test compared with the DLL and TR tests, the SR test was excluded from calculation of an overall score. Based on raw data distribution from the DLL and TR tests, the DLL data were categorized into 10º increments, allowing construction of a 10-point score. The median AWS score was 5 (interquartile range [IQR], 4-7), and there was agreement within 1 point for 42 of the 45 encounters (93%). The findings from this study demonstrate that the 10-point AWS score may measure AWS in an accurate and reproducible fashion, with potential for objective description of abdominal wall function of VIH patients. This score may help to identify patients suited for abdominal wall reconstruction while measuring progress after VIH repair. Further longitudinal outcomes studies are needed.

    Full Text Available Abstract Background and objectives: The quadratus lumborum blockade was described by R. Blanco in its two approaches (I and II. The local anesthetic deposition in this location can provide blockade to T6-L1 dermatomes. We performed this fascia blockade guided by ultrasound for treating a chronic neuropathic pain in the abdominal wall. Case report: Male patient, 61 years old, 83 kg, with a history of thrombocytopenia due to alcoholic cirrhosis, among others; had chronic pain in the abdominal wall after multiple abdominal hernia repairs in the last year and a half, with poor response to treatment with neuromodulators and opioids. On clinical examination, he revealed a neuropathic pain, with prevalence of allodynia to touch, covering the entire anterior abdominal wall, from T7 to T12 dermatomes. We opted for a quadratus lumborum block type II, guided by ultrasound, with administration of 0.2% ropivacaine (25 mL and depot (vial methylprednisolone (20 mg on each side. The procedure gave immediate relief of symptoms and, after six months, the patient still had a significant reduction in allodynia without compromising the quality of life. Conclusions: We consider that performing the quadratus lumborum block type II was an important analgesic option in the treatment of a patient with chronic pain after abdominal hernia repair, emphasizing the effects of local anesthetic spread to the thoracic paravertebral space. The technique has proven to be safe and well tolerated. The publication of more clinical cases reporting the effectiveness of this blockade for chronic pain is desirable.

    Full Text Available We describe here a case of abdominal abscesses due to Mycobacterium fortuitum following liposuction. The abscesses developed three months after the procedure and diagnosis was delayed for five months. The clues for diagnosis were persistent pus discharge in spite of broad spectrum antibiotics and failure to grow any organisms on routine culture. This condition has been rarely reported; however, the increasing number of liposuction procedures done and awareness among physicians will probably result in the identification of more cases. Combination antibiotic therapy with surgical drainage in more extensive diseases is essential for cure.

    2016-10-01

    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.

Here, we present the case of a child whose initial hypothesis of diagnosis contemplated this possibility. Later, it was demonstrated that the abdominal mass found was secondary to a common parasitosis. A 2-year old, moderately malnourished and pale white boy was referred with a history of a rapidly growing, well-limited, middle abdominal mass. The mass was 10 by 3 cm, hard and poorly movable, apparently involving both abdominal rectus muscles. A complete resection was performed, revealing an abdominal wall abscess, with intense eosinophilic proliferation, secondary to a local and intense reaction to innumerous Ascaris lumbricoides eggs. Extra luminal infestations with Ascaris, that usually form peritoneal granulomas have been previously described. However, neither external trauma nor fistula, that could explain the superficial presence of the eggs, was found. This description reinforces the relevance of infectious diseases within the differential diagnosis of abdominal masses, particularly in areas with high prevalence of parasitic infestations.

    A prospective study of all infrarenal abdominal aortic aneurysm (AAA) repairs both as electives and emergencies in Penang between January 1997 to December 2000 is presented. The objectives of the study were to determine the age, gender, racial distribution of the patients, the incidence, and risk factors and to summarize treatments undertaken and discuss the outcome. Among the races, the Malays were the most common presenting with infrarenal AAA. The mean age of patients operated was 68.5 years. Males were more commonly affected compared to females (12:1). Most infrarenal AAA repairs were performed as emergency operations, 33 cases (61.1%) compared to electives, 21 cases (38.9%). Total survival was 70.3% (elective 85.7%; emergency 57.6%). Mortality rate was 31.5% and the primary reason is the lack of operating time available for urgent operation and for treatment of concurrent disease states. Mycotic aneurysm with its triad of abdominal pain, fever and abdominal mass resulted in a significantly higher mortality (46.6%). Ninety six percent of the infrarenal AAA had transverse diameter greater than 6 cm. Morphologically 90.7% were fusiform AAA rather than saccular aneurysm (9.3%). Pulmonary complications (35.2%) were more common than cardiac complications (11.1%) possibly related to the urgent nature of the operation, smoking or history of pulmonary tuberculosis. Bleeding (14.8%) was the most common cause of mortality in ruptured mycotic infrarenal AAA.

    Human omphalocele is a congenital defect of the abdominal wall in which the secondary abdominal wall structures (muscle and connective tissue) in an area centered around the umbilicus are replaced by a translucent membranous layer of tissue. Histological examination of omphalocele development and moreover the staging of normal human abdominal wall development has never been described. We hypothesized that omphalocele is the result of an arrest in the secondary abdominal wall development and p...

    The aim of this study is to characterize the passive mechanical behaviour of abdominal wall in vivo in an animal model using only external cameras and numerical analysis. The main objective lies in defining a methodology that provides in vivo information of a specific patient without altering mechanical properties. It is demonstrated in the mechanical study of abdomen for hernia purposes. Mechanical tests consisted on pneumoperitoneum tests performed on New Zealand rabbits, where inner pressure was varied from 0mmHg to 12mmHg. Changes in the external abdominal surface were recorded and several points were tracked. Based on their coordinates we reconstructed a 3D finite element model of the abdominal wall, considering an incompressible hyperelastic material model defined by two parameters. The spatial distributions of these parameters (shear modulus and non linear parameter) were calculated by inverse analysis, using two different types of regularization: Total Variation Diminishing (TVD) and Tikhonov (H(1)). After solving the inverse problem, the distribution of the material parameters were obtained along the abdominal surface. Accuracy of the results was evaluated for the last level of pressure. Results revealed a higher value of the shear modulus in a wide stripe along the craneo-caudal direction, associated with the presence of linea alba in conjunction with fascias and rectus abdominis. Non linear parameter distribution was smoother and the location of higher values varied with the regularization type. Both regularizations proved to yield in an accurate predicted displacement field, but H(1) obtained a smoother material parameter distribution while TVD included some discontinuities. The methodology here presented was able to characterize in vivo the passive non linear mechanical response of the abdominal wall. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Full Text Available Endometriosis is a frequent benign disorder. Malignancy arising in extraovarian endometriosis is a rare event. A 49-year-old woman is presented with a large painful abdominal wall mass. She underwent a myomectomy, 20 years before, for uterus leiomyoma. Computed tomography suggested that this was a desmoid tumor and she underwent surgery. Histological examination showed a clear cell adenocarcinoma associated with endometriosis foci. Pelvic ultrasound, computed tomography, and endometrial curettage did not show any malignancy or endometriosis in the uterus and ovaries. Adjuvant chemotherapy was recommended, but the patient was lost to follow up. Six months later, she returned with a recurrence of the abdominal wall mass. She was given chemotherapy and then she was reoperated.

    Abdominal wall actinomycosis without pelvic organ involvement in users of intrauterine contraceptive devices (IUDs) has not been reported on previously. We encountered one such patient, whose uterine cervix was colonized superficially with Actinomyces. We suggest that systemic actinomycosis be included in the differential diagnosis of pain in IUD users when Actinomyces is found on Papanicolaou smears or in endocervical curettings. Such patients should be treated with appropriate antibiotic therapy, especially prior to any surgical intervention.

    We describe our experience with the use of N-butyl cyanoacrylate (NBCA) embolization of abdominal wall bleeding and we evaluate the clinical effectiveness of the procedure. Embolization was performed in nine patients with abdominal wall bleeding. The sites of embolization were the left first lumbar (n = 1), left second lumbar (n = 1), right inferior epigastric (n 2), left inferior epigastric (n = 3), right circumflex iliac (n = 1), and left circumflex iliac artery (n = 1). A coil was used with NBCA in one patient due to difficulty in selecting only a bleeding focus and anticipated reflux. NBCA was mixed with Lipiodol at the ratio of 1:1 to 1:4. Blood pressure and heart rate were measured before and after the embolization procedure, and the serial hemoglobin and hematocrit levels and transfusion requirements were reviewed to evaluate hemostasis and rebleeding. Hemostasis was obtained in six out of the nine patients and technical success was achieved in all patients. There were no procedure-related complications. Four out of the nine patients died due to rebleeding of a subarachnoid hemorrhage (n = 1), multiorgan failure (n = 1), and hepatic failure (n =2) that occurred two to nine days after the embolization procedure. One patient had rebleeding. The five surviving patients had no rebleeding, and the patients continue to visit the clinical on an outpatient basis. NBCA embolization is a clinically safe procedure and is effective for abdominal wall bleeding.

    Congenital abdominal wall defects are common anomalies which include gastroschisis, omphalocele and umbilical cord hernia. Recent reports indicate that gastroschisis is increasing in prevalence, whereas omphalocele has remained steady, suggesting that environmental factors may play a part in their pathogenesis. The aim of this study is to review animal teratogen studies resulting in abdominal wall defects to investigate their possible causes. Each report was examined not only for the teratogens causing the defects, but also to carefully identify the defect occurring and its correlation with the known clinical anomalies. We found many discrepancies between the nomenclature used by animal teratology investigators and that used by clinicians. We were able to confirm the induction of gastroschisis by 22 teratogens, omphalocele by 9 teratogens and umbilical cord hernia by 8. There is no doubt that environmental factors may be responsible, at least in part, for all three of the clinical abdominal wall defects. Future studies should take care to appreciate the differences between these anomalies and describe them in detail, so that accurate and meaningful conclusions can be obtained.

    2005-11-01

    As an abdominal aortic aneurysm develops, large changes occur in the composition and structure of the arterial wall, which result in its stiffening. So far, most studies, whether experimental or numerical, have been conducted assuming the walls to be rigid. A numerical simulation of the fluid structure interactions is performed in different models of aneurysms in order to analyze the effects that the wall compliance might have on the flow topology. Both symmetric and non-symmetric models of aneurysms are considered, all idealistic in shape. The wall mechanical properties are varied in order to simulate the progressive stiffening of the walls. The spatial and temporal distributions of wall tension are calculated for the different values of the wall elasticity and compared to the results for the rigid walls. In the case of rigid walls, the calculation of the wall shear stresses and pressure compare very well with experimental results.

    Abdominal hernias are a common clinical problem Clinical diagnosis of abdominal hernias can sometimes be challenging, particularly in obese patients or patients with previous abdominal surgery. CT scan of the abdomen allows visualization of hernias and their contents and the differentiation from other masses of the abdominal wall such as tumors, hematomas and abscesses. Moreover, CT may identify complications such as incarceration, bowel obstruction, volvulus and strangulation. This study illustrates the CT scan findings observed in different types of abdominal wall hernias. (author)

    To evaluate the clinical utility of GORE® DUALMESH (GDM) in the staged closure of large congenital abdominal wall defects. Data of patients with congenital abdominal wall defects managed with GDM was analyzed for outcome regarding complete fascial closure; mesh related complications; and post-discharge gastrointestinal surgery. GDM was placed in 34 (gastroschisis=27, omphalocele=7) patients during the study period. Complete closure of the fascia was obtained in one patient with omphalocele and in 22 patients with gastroschisis. Mesh related surgical complications were seen in five (15%) children: four had detachment of the mesh and one patient developed abdominal compartment syndrome. Mesh related clinical infection was observed in five children. In hospital mortality occurred in four cases (2 gastroschisis and 2 omphalocele) and was not procedure-related. Of the 30 children discharged, 28 (82%) were still alive. At follow-up, three patients (10%) were operated for a minor ventral hernia and 4 children were operated (laparotomy and adhesionolysis) for adhesive intestinal obstruction. Staged closure with GDM is a safe alternative when primary fascial closure is difficult.

    Full Text Available Two most common anterior abdominal wall defects are gastroschisis and omphalocoele or exomphalos. Gastroschisis means 'stomach cleft' which is a congenital defect of the abdominal wall, usually to the right of the umbilical cord insertion and abdominal contents herniate into the amniotic sac. Exomphalos is literally translated from the Greek, means 'outside the navel'. It is also called an Omphalocele. It is a congenital abnormality in which the contents of the abdomen herniate into the umbilical cord through the umbilical ring. Textbooks grouped them together but these are different entities. These congenital malformations have a high mortality rate. Only about 60 % of children with such type of malformations survive until the end of first year of age. A male foetus of 32 weeks gestational age was sent from Dr. Ulhas Patil Medical College and Hospital, Jalgaon (Khurd to the Department of Anatomy to examine the fetus for congenital anomalies. A case report of an Omphalocele was presented. Occurrence of such cases is very rare about 2.17 per 10000 live births as reported in literature.

    Abdominal wall hernias are a common problem. The success of abdominal wall reconstruction decreases with increasing hernia size. This study summarizes the outcomes of one surgeon's experience using a "sandwich" technique for hernia repair in patients with loss of abdominal domain. We reviewed our ventral hernia repair (VHR) experience from 2008 to 2015 among patients with loss of domain, as defined by a hernia defect greater than 300 cm(2). The percent of herniation through the defect, defined by a hernia sac-to-abdominal cavity volume ratio, was measured on preoperative CT scans by four independent reviewers and averaged. Outcomes were compared among those with giant ventral hernias (hernia sac-to-abdominal cavity volume >30%) and those with smaller defect ratios. Over the study period, 21 patients underwent VHR. In 17 patients (81%), a "sandwich" technique was utilized. Ten patients had hernia sac-to-abdominal cavity defects less than 30%, and 11 had defects greater than 30%. Preoperative characteristics were similar in both groups with the exception of a higher ASA score in those with giant ventral hernias and more Ventral Hernia Working Group Grade 3 hernias in those without giant ventral hernias. Postoperative outcomes were similar in both groups. There were no mortalities. There were two recurrences (18%) in the giant VHR group and none in the smaller defect group (p = 0.16). Surgical site occurrences were noted in 48% of patients and did not differ between giant and non-giant VHR groups (50 vs 45%, p = 0.84). Average postoperative length of stay was significantly longer in the giant VHR group (31 vs. 17 days, p = 0.03). Our results suggest that the "sandwich" technique for VHR is a safe and durable method to restore abdominal wall integrity in those with LOD, even in patients with giant ventral hernias.

    A surgical technique currently used in the treatment of Abdominal Aortic Aneurysms (AAA) is the Endovascular Aneurysm Repair (EVAR). This minimally invasive procedure involves inserting a prosthesis in the aortic vessel that excludes the aneurysm from the bloodstream. The stent, once in place acts as a false lumen for the blood current to travel down, and not into the surrounding aneurysm sac. This procedure, therefore, immediately takes the pressure off the aneurysm, which thromboses itself after some time. Nevertheless, in a long term perspective, different complications such as prosthesis displacement or bloodstream leaks into or from the aneurysmatic bulge (endoleaks) could appear causing a pressure elevation and, as a result, increasing the danger of rupture. The purpose of this work is to explore the application of image registration techniques to the visual detection of changes in the thrombus in order to assess the evolution of the aneurysm. Prior to registration, both the lumen and the thrombus are segmented

    Low back pain is associated with dysfunction in recruitment of muscles in the lumbopelvic region. Effective rehabilitation requires preferential activation of deep stabilizing muscle groups. This study was carried out in order to quantify the response of deep stabilizing muscles (transverses abdominis) and superficial muscle in the abdominal wall (external oblique) to electrical muscle stimulation (EMS). Results demonstrate that EMS can preferentially stimulate contractions in the deep stabilizers and may have significant potential as a therapeutic intervention in this area, pending further refinements to the technology.

    Rhabdomyosarcoma encompasses a group of malignant myogenic neoplasms expressing a multitude of clinical and pathological diversities. It is the commonest soft tissue sarcoma of childhood but neonates are rarely affected. Embryonal subtype is the most frequent. Head-neck and genitourinary tracts are predominant sites, while trunk is considered among the unusual sites of rhabdomyosarcoma. Herein we report a case of anaplastic rhabdomyosarcoma in a newborn girl presenting, at the Pediatric Surgery Outpatient Department of North Bengal Medical College and Hospital, India in 2013 with a large tumor mass in the left flank region, arising from abdominal wall muscles.

    Mucormycosis is caused by saprophtytic fungi which cause acute invasive zygomycosis. It clinically presents with necrosis, and on histopathology, acute and chronic infiltrates are seen. It rarely infects a healthy host, but is devastating in an immunocompromised host. We studied five cases with post-operative abdominal wall mucormycosis, three females and two males. Three patients were post-operative while the other two had mucormycosis following trauma and infection was found in sutured wound. All were initially diagnosed as cases of necrotizing fasciitis. Two patients eventually survived after intensive medical therapy and extensive debridements.

  5. Cadaver as an experimental model to study abdominal wall tension

    2003-01-01

    Full Text Available The use of cadaver as an experimental model to evaluate tension of the abdominal wall after aponeurotic incisions and muscular undermining is described on this article. The tension required to pull the anterior and the posterior rectus sheaths towards the midline was studied in fresh cadavers at two levels: 3 cm above and 2 cm below the umbilicus. Traction measurement was assessed with a dynamometer attached to suture loops on the anterior and posterior recti sheaths, close to the midline, above and below the umbilicus. The quotient of the force used to mobilize the aponeurotic site to the midline and its resulting displacement was called the traction index. These indices were compared in three situations: 1 prior to any aponeurotic undermining; 2 after the incision of the anterior rectus sheath and the undermining of the rectus muscle from its posterior sheath; and 3 after additionally releasing and undermining of the external oblique muscle. The experimental model described showed to be feasible to demonstrate the effects on tension of the abdominal wall after incisions and undermining of its muscles and aponeurosis.

    Complex iliac anatomy including extreme tortuosity constitutes a relative contraindication for endovascular abdominal aortic aneurysm repair with additional risk of limb-graft occlusion. The Gore Excluder limb-graft is a flexible stent-graft, which adapts easily to iliac tortuosity. Nevertheless, the presence of the stiff guide wire does not always allow for an ideal apposition of the stent graft to the angulated common iliac artery vessel wall. We describe herein a modified technique for Gore Excluder limb-graft deployment with partial removal of the stiff wire in cases with difficult tortuous or narrow iliac arteries during endovascular abdominal aortic aneurysm repair. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    The lateral abdominal wall is comprised of three muscles, each with a different function and orientation. The transversus abdominus, internal oblique, and external oblique muscles span the abdominal cavity between the iliocostalis lumborum and quadratus lumborum posteriorly and the rectus abdominis anteriorly. The lateral abdominal wall is bound superiorly by the lower ribs and costal cartilages and inferiorly by the iliac crest and inguinal ligament. The lateral abdominal wall may be acutely or chronically injured in a variety of athletic endeavors, with occasional acute injuries in the setting of high-energy trauma such as motor vehicle collisions. Injuries to the lateral abdominal wall may result in lumbar hernia formation, unique for its high incarceration rate, and also Spigelian hernias. This article will review the anatomy, the magnetic resonance (MR) imaging approach, and the features and complications of lateral abdominal wall injuries.

    Objective To compare the characteristics of two compound patches made of collagen and polypropylene(PP) and the feasibility of their application in repair of contaminated wounds. Methods Twenty-four adult male dogs, weighing 16-20kg, were included in this study. A dog model with 3 contaminated defects at the upper, left and right abdominal wall was established. The 3 abdominal wall defects were repaired by implanting 3 kinds of patches into them. The patches were divided into PP and collagen compound patch group(group A), porcine cross-linked biologic patch group(group B), and cattle cross-linked biologic patch group(group C). A dog abdominal hernia model was established. A segment of small intestine was removed, into which 10ml 0.9% sodium chloride solution was injected and then aspirated to contaminate the abdominal cavity, abdominal wall and patches. The abdominal wall defects were closed with 5cm × 5cm patches. The dogs were killed on day 90 after operation to observe the adhesion of organs in abdominal cavity. The patches and their adjacent tissue were cut into sections for histological study. Results No death occurred while patch and omentum adhesion was observed in different groups 90 days after operation. Histological study showed that the scores of proliferating fibroblasts, inflammatory reaction and formation of new blood vessels were higher in group A than in groups B and C. Conclusion The effect of PP and collagen compound patch and biological patch is similar in preventing adhesion under contaminated environment. However, it leads to severer proliferation of fibroblasts, inflammatory reaction and formation of new blood vessels than biologic patch.%目的 比较胶原蛋白与聚丙烯(polypropylene,PP) 制作的复合补片和两种生物补片的特点及其应用于污染伤口一期修补的可行性.方法 成年雄性普通犬24 只,体质量16-20kg,在同一只动物上、左、右腹部建立三个污染缺损模型,将3 种补

    2015-12-01

    Abdominal wall hernias are increasingly treated by laparoscopic placement of an intraperitoneal onlay mesh (IPOM). We present an alternative technique for women: the laparoscopic-assisted transvaginal IPOM. Before surgery, all patients underwent a gynecological examination. The patients agreed to IPOM repair via a transvaginal approach, and written informed consent for surgery was obtained. Pneumoperitoneum was established with a Veress needle at the umbilicus. This access was subsequently dilated to 5 mm (VersaStep), and a 5-mm laparoscope was inserted. Under laparoscopic view, the transvaginal trocars (12-mm VersaStep and 5-mm flexible accesses) were safely inserted after lifting the uterus with a uterus manipulator. After preparation of the falciform ligament, the ligamentum teres and the preperitoneal fat, a lightweight composite mesh was introduced through the transvaginal access and fixed with absorbable tacks using the double-crown technique. From September 2011 to December 2012, we performed six laparoscopic-assisted transvaginal IPOM procedures (one epigastric, three umbilical, two combined epigastric and umbilical hernias; all were primary hernias). In the initial phase, only patients with small or medium primary abdominal wall hernia were selected (max. 3 cm diameter). Median hospital stay was 3 days (range 2-6 days). One minor complication occurred perioperatively (second-degree skin burn to the labia majora). At 1-year follow-up, we identified one recurrence in a high-risk patient with a body mass index higher than 35 kg/m(2). No infection and no mortality were observed. Although no final conclusion can be made regarding the presumed non-inferiority of this technique in terms of recurrence and mesh infection compared with traditional laparoscopic IPOM, laparoscopic-assisted transvaginal IPOM is a feasible alternative to treat abdominal wall hernias.

    We measured abdominal compliance (Cab) and rib cage displacement (delta Vrc) relative to abdominal displacement (delta Vab) during relaxation and tidal breathing in upright (U) and supine (S) postures in five normal subjects. In S, an abdominal binder was used to decrease Cab in two to five increments. We also measured the electrical activity of the parasternal muscle (EMGps) with the use of fine-wire intramuscular electrodes during CO2 rebreathing in U and in supine unbound (SU) and supine bound (SB) postures. During maximum binding (SB2), Cab decreased to 39 +/- 7% of the SU value (P = 0.01), matching Cab in U (P = 0.16). In the SB condition, the ratio of tidal delta Vrc/delta Vab to relaxation delta Vrc/delta Vab increased as Cab decreased, matching the data in U. For the group, this ratio decreased during SU to 47 +/- 10% (P = 0.02) but increased during SB2 to 86 +/- 7% (P = 0.18) of the value in U. During CO2 rebreathing, EMGps increased linearly with tidal volume (r > 0.727, P < 0.01). However, at any given tidal volume, the SU and SB2 EMGps were not significantly different (P = 0.12), and both were less than that in U (P < 0.02). The results suggest that the differences in chest wall motion between U and S may be due to the difference in Cab and not to different patterns of respiratory muscle recruitment. The mechanism may relate to changes in mechanical coupling between the diaphragm and the rib cage.

    A 49 year-old patient with the complaint of a mass located in the caesarean scar was admitted. There was a fixed mass 30í30 mm in diameter with regular contour located at the right corner of the pfannenstiel incision. Computed tomography revealed a (40í50í50) mm solid mass lesion with margins that cannot be distinguished from the uterus, bladder and small intestines and a heterogeneous mass lesion (50í45í55) mm in diameter, located in the right side of the anterior abdominal wall. Cytoreductive surgery including total abdominal hysterectomy and bilateral salpingo-oophorectomy was performed. Final pathology was clear cell carcinoma. Clear cell carcinoma arising from an extraovarian endometriotic focus was diagnosed and the patient received 6 cycles paclitaxel-carboplatin chemotherapy as adjuvant treatment. The patient who was lost to follow-up applied to our clinic 2 years after surgery with a recurrent mass in the left inguinal region. After 3 cycles of chemotherapy, the patient's tumoral mass in the left inguinal region was excised. The result of the pathology was carcinoma metastasis. It is decided that the following treatment of the patient should be palliative radiation therapy. The patient who underwent palliative radiation therapy died of disease after 4 months of the second operation.

    Surgical implants are commonly used in abdominal wall surgery for hernia repair. Many different prostheses are currently offered to surgeons, comprising permanent synthetic polymer meshes and biologic scaffolds. There is a wide range of synthetic meshes currently available on the market with differing chemical compositions, fiber conformations, and mesh textures. These chemical and structural characteristics determine a specific biochemical and mechanical behavior and play a crucial role in guaranteeing a successful post-operative outcome. Although an increasing number of studies report on the structural and mechanical properties of synthetic surgical meshes, nowadays there are no consistent guidelines for the evaluation of mechanical biocompatibility or common criteria for the selection of prostheses. The aim of this work is to review synthetic meshes by considering the extensive bibliography documentation of their use in abdominal wall surgery, taking into account their material and structural properties, in Part I, and their mechanical behavior, in Part II. The main materials available for the manufacture of polymeric meshes are described, including references to their chemical composition, fiber conformation, and textile structural properties. These characteristics are decisive for the evaluation of mesh-tissue interaction process, including foreign body response, mesh encapsulation, infection, and adhesion formation. © 2015 Wiley Periodicals, Inc.

    Objective: To review the clinical characteristics, treatment and prognoses of abdominal wall endometriosis(AWE).Methods: A retrospective study of 101 cases of AWE from 1992 to 2005 at Obstetric and Gynecologic Department of Peking Union Medical College Hospital was performed. Ninety-eight patients had a history of caesarean section. The mean age of the patients was (33.3±4.8) years and the average size of the mass was 1.5 cm. Abdominal wall mass associated pain during the menstrual cycle was noticed in 89.8% of the patients. The occurrence of AWE after caesarean section was 0.05% at our hospital. In patients without pelvic endometriosis or adenomyosis, 20.5% were presented with high CA125 >35 U/ml and the highest one was 93.4 U/ml. 92.1% of patients were diagnosed before surgery. 4 patients were administrated first in General Surgical Department with painless abdominal mass. Medication was adopted in 16 cases pre-operatively and 14 cases post-operatively.Results: The mean size of the resected mass was 4.2 cm, significantly larger than the estimation with palpation or ultrasonography, which was 0.8-1.2 cm (P=0.006, P<0.001). Pelvic endometriosis or adenomyosis was detected during the operation in 13 patients. One patient was diagnosed as atypical endometriosis by pathological examination in the beginning but transformed to be sarcoma finally. Ten patients recurred after surgery. 2 of them received medication and 5 of them received second operation.Conclusions: Ultrasonography can be used to evaluate the size of the mass and the infiltrative scope pre-operation. The serum CA125 is not specific for diagnosis of AWE. Complete eradication of the lesion with at least 1 cm beyond the edge of the mass is recommended as the primary treatment. Eradication should be considered also in recurrent cases. It may transform to malignant lesions after multiple recurrence.

  19. Traumatic Abdominal Wall Hernia After a Blunt Trauma: A Case Report

    2014-06-01

    Full Text Available Traumatic abdominal wall hernia is a rare result of blunt abdominal traumas in adults. Altough the detection of the injuries of the abdominal organs is the priority in blunt traumas, abdominal wall defect may also occur in these patients. These hernias can go undetected due to preservation of the skin overlying the hernia defect. Traumatic abdominal wall hernias can have high morbidity and mortality rates due to incarceration and perforation of tubular hollow organs, especially if there is any delay. The possibility of traumatic hernia should always be considered in cases with serious blunt trauma. Computed Tomography (CT scan examinations should be performed routinely due to their high diagnostic value if trumatic hernia is suspected. In this report, a traumatic abdominal wall hernia patient who was treated by surgery has been presented with the review of the current literature.

    Human omphalocele is a congenital defect of the abdominal wall in which the secondary abdominal wall structures (muscle and connective tissue) in an area centered around the umbilicus are replaced by a translucent membranous layer of tissue. Histological examination of omphalocele development and moreover the staging of normal human abdominal wall development has never been described. We hypothesized that omphalocele is the result of an arrest in the secondary abdominal wall development and predicted that we would observe delays in myoblast maturation and an arrest in secondary abdominal wall development. To look for evidence in support of our hypothesis, we performed a histological analysis of normal human abdominal wall development and compared this to mouse. We also conducted the first histological analysis of two human specimens with omphalocele. In these two omphalocele specimens, secondary abdominal wall development appears to have undergone an arrest around Carnegie Stage 19. In both specimens disruptions in the unidirectional orientation of myofibers were observed in the external and internal obliques, and rectus abdominis but not in the transversus abdominis. These latter findings support a model of normal abdominal wall development in which positional information instructs the orientation of myoblasts as they organize into individual muscle groups.

    2004-09-01

    We report three cases of abdominal wall necrotizing fasciitis that occurred as a result of leakage from displaced percutaneous endoscopic gastrostomy tubes. This is the first report of such a series. Patients underwent extensive operative excisions of their abdominal walls down to their posterior fascia. All patients tolerated their initial surgery, however, two patients ultimately expired from respiratory complications. The surviving patient underwent multiple repeat debridements and reconstructive abdominal wall surgery. We review the epidemiology of patients at risk for this complication and discuss its presentation, as well as the appropriate workup and management. We also address the issues of closure of large abdominal wall defects and future alimentation in this patient group. Finally, abdominal wall necrotizing faciitis from gastrostomy tube leakage is a devastating complication, and the development of preventative strategies for patients at risk is of paramount importance.

    Full Text Available PURPOSE: The aim of this study was to assess abdominal wall healing in old and young adult rats. METHODS: On average, young animals were 110 days old and old animals were 762 days old. A 4.0 cm median laparotomy was performed under anesthesia, followed by laparorrhaphy on two synthesis planes, i.e. peritoneum-muscle-aponeurosis and skin, using continuous 5.0 nylon sutures. The animals were evaluated on the 3rd, 7th, 14th and 21st postoperative days. The resistance of the two planes was studied separately and a histopathologic analysis was performed on sections stained with hematoxylin-eosin and Sirius Red. Immunohistochemical analysis was also carried out using PCNA, LCA and CD34. RESULTS: The skin scars gained resistance in a similar manner at the initial time points, but those of young rats were more resistant on the 21st day (p=0.0029. Total and type III collagen content was similar in the two groups and type I collagen content was higher in young animals on the 14th day. Inflammatory cell infiltration was more marked in the skin wounds of young animals on the 3rd day (p=0.0190. Reepithelialization was similar and angiogenesis was more intense in the skin wounds of young animals on the 14th day (p=0.0062. The peritoneum-muscle-aponeurosis wounds gained similar resistance during the early phases, but were more resistant on the 14th day (p=0.0005 and on the 21st day (p=0.0023 in old rats Collagen concentration was higher in the wounds of old animals on the 3rd day (p=0.0112 and in the wounds of young animals on the 21st day (p=0.0348. The inflammatory reaction was more intense in the wounds of old animals on the 3rd day (p=0.0060 and angiogenesis was more intense on the 14th day (0.0432. CONCLUSION: Although there are some differences in the healing course between young and old animals, age, of itself, does not impair the healing of abdominal wall wounds in rats.

    An 86-year-old man with an abdominal aortic aneurysm was diagnosed with type B aortic dissection accompanied by a patent false lumen that started at the distal arch of the thoracic aorta and terminated at the left common iliac artery. Meticulous preoperative assessment detected 3 large intimal tears in the descending aorta, abdominal aortic aneurysm, and left common iliac artery. We performed single-stage thoracic and abdominal endovascular aneurysm repair and concomitant axillary-axillary bypass. The abdominal aortic aneurysm with type B aortic dissection was successfully treated using a single-stage endovascular stent graft, without any complications due to the careful preoperative examinations.

    The most common surgical repair of abdominal wall hernia goes through implanting a mesh that substitutes the abdominal muscle/fascia while it is healing. To reduce the risk of relapse or possible complications, this mesh needs to mimic the mechanical behavior of the muscle/fascia, which nowadays is not fully determined. The aim of this work is to develop a methodology to characterize in vivo the passive mechanical behavior of the abdominal wall. For that, New Zealand rabbits were subjected to pneumoperitoneum tests, taking the inner pressure from 0 mmHg to 12 mmHg, values similar to those used in human laparoscopies. Animals treated were divided into two groups: healthy and herniated animals with a surgical mesh (polypropylene Surgipro(TM) Covidien) previously implanted. All experiments were recorded by a stereo rig composed of two synchronized cameras. During the postprocessing of the images, several points over the abdominal surface were tracked and their coordinates extracted for different levels of internal pressure. Starting from that, a three dimensional model of the abdominal wall was reconstructed. Pressure-displacement curves, radii of curvature and strain fields were also analysed. During the experiments, animals tissue mostly deformed during the first levels of pressure, showing the noticeable hyperelastic passive behavior of abdominal muscles. Comparison between healthy and herniated specimen displayed a strong stiffening for herniated animals in the zone where the high density mesh was situated. Cameras were able to discern this change, so this method can be used to measure the possible effect of other meshes.

    Abdominal wall endometriosis (AWE) is defined as endometrial tissue that is superficial to the peritoneum. AWE is often difficult to diagnose, mimicking a broad spectrum of diseases. The aim of this study was to describe the appearance of AWE on magnetic resonance (MR) imaging. We present ten patients with AWE (12 lesions) in which MR imaging was used for diagnosis. MR imaging included T2-weighted imaging and T1-weighted imaging with fat suppression. To assess the value of diffusion-weighted imaging (DWI) in endometriosis, four patients underwent additional DWI. The apparent diffusion coefficient (ADC) was calculated using b values of 50, 400, 800 and 1,200 s/mm{sup 2}. In most cases, the lesion was located ventral or dorsal to the aponeurosis of the rectus oblique muscle (n=6) or in the rectus abdominis (n = 5). MR of AWE lesions showed isointense or slightly hyperintense signal compared with muscle on T2-weighted images and showed isointense or slightly hyperintense signal compared with muscle on T1-weighted images with foci of high signal intensity, indicative of haemorrhage. The mean ADC value of AWE was 0.93 x 10{sup -3}/mm{sup 2}/s. MR imaging seems to be useful in determining the location and depth of infiltration in surrounding tissue preoperatively. (orig.)

    To assess knowledge on the abdominal wall closure through a surgeon cohort survey. A twenty question individual questionnaire on laparotomy in elective surgery. A total of 131 surgeons from seven hospitals responded (72% specialists and 28% in training). 71% of respondents estimated the frequency of incisional hernia to be higher than 15% and 54% considered the technique to be the most significant risk factor. 85% considered midline laparotomy closed with slow absorbable suture (57%) in a single layer (66%) to be the most appropriate technique. 67% believed retention sutures to be the appropriate prevention technique. 50% did not know or could not apply the 4:1 technique. 87% considered that an incisional hernia can be prevented and that the technique is the most important factor on which to act. 84% believed that a prosthesis can prevent the occurrence of incisional hernia, whereas 40% of respondents never use it and only 38% use it in patients at risk. On comparing surveys between specialists and residents, significant differences appeared in terms of a better understanding of the theoretical technical aspects in trainee surgeons. Although the results show an adequate understanding of the epidemiology and risk factors for development of incisional hernia, training and consensus measures are likely to be introduced in some basic technical aspects in order to improve results in laparotomy closure.

    Abdominal wall leiomyoma arising de novo is very rare, hence the reported imaging findings of this disease are also rare. We reported the case of a 33-year-old woman who presented with an abdominal wall mass without antecedent gynecological surgeries. The initial abdominal computed tomography (CT) showed thickening of the left rectus abdominis and the loss of intervening fat between the rectus abdominis and the lateral abdominal muscles. After 8 months, the follow-up contrast-enhanced CT and ultrasonography (US) showed a lentiform-shaped mass with isodensity to the adjacent muscles. The US-guided biopsy was consistent with leiomyoma.

    Sonography is usually regarded as a first-line imaging modality for masses and masslike lesions in the abdominal wall. A dynamic study focusing on a painful area or palpable mass and the possibility of ultrasound-guided aspiration or biopsy are the major advantages of sonography. On the other hand, cross-sectional imaging clearly shows anatomy of the abdominal wall; thereby, it is valuable for diagnosing and evaluating the extent of diseases. Cross-sectional imaging can help differentiate neoplastic lesions from non-neoplastic lesions. This pictorial essay focuses on sonographic findings of abdominal wall lesions compared with computed tomographic and magnetic resonance imaging findings.

    Myofascial defects of lateral abdominal wall and lumbar region occur chiefly after lumbotomy--the most popular access in urosurgery. Meanwhile lumbotomy remains one of the most traumatic accesses through the lateral abdominal wall. Myofascial defects were diagnosed in 48,9% of operated patients with lumbotomy. Of them true postoperative hernias were found in 35,3%; neuropathic hernias - in 13,6%. Since 2002 the originally developed method of lateral abdominal wall reconstruction had been used for the treatment of such patients. The immediate and long-term results (maximal follow-up period 5 years) showed no hernia recurrence or complications in 26 operated patients.

    Open repair is still considered the reference standard for long-term repair of abdominal aortic aneurysms (AAA). In contrast to endovascular aneurysm repair (EVAR), patients with open surgical repair of AAA are not routinely followed up with imaging. Although complications following EVAR are widely recognized and routinely identified on follow-up imaging, complications also do occur following open surgical repair. With frequent use of multi-slice computed tomography (CT) angiography (CTA) in vascular patients, there is now improved recognition of the potential complications following open surgical repair. Many of these complications are increasingly being managed using endovascular techniques. The aim of this review is to illustrate a variety of potential complications that may occur following open surgical repair and to demonstrate their management using both surgical and endovascular techniques.

    Patient outcomes after open abdominal aortic aneurysm and endovascular aortic aneurysm repair have been widely reported from several large, randomized, controlled trials. It is not clear whether these trial outcomes are representative of abdominal aortic aneurysm repair procedures performed in real-world hospital settings across the United States. This study was designed to evaluate population-based outcomes after endovascular aortic aneurysm repair versus open abdominal aortic aneurysm repair using statewide inpatient databases and examine how they have helped improve our understanding of abdominal aortic aneurysm repair. A systematic search of MEDLINE, EMBASE, and CINAHL databases was performed to identify articles comparing endovascular aortic aneurysm repair and open abdominal aortic aneurysm repair using data from statewide inpatient databases. This search was limited to studies published in the English language after 1990, and abstracts were screened and abstracted by 2 authors. Our search yielded 17 studies published between 2004 and 2016 that used data from 29 different statewide inpatient databases to compare endovascular aortic aneurysm repair versus open abdominal aortic aneurysm repair. These studies support the randomized, controlled trial results, including a lower mortality associated with endovascular aortic aneurysm repair extended from the perioperative period up to 3 years after operation, as well as a higher complication rate after endovascular aortic aneurysm repair. The evidence from statewide inpatient database analyses has also elucidated trends in procedure volume, patient case mix, volume-outcome relationships, and health care disparities associated with endovascular aortic aneurysm repair versus open abdominal aortic aneurysm repair. Population analyses of endovascular aortic aneurysm repair and open abdominal aortic aneurysm repair using statewide inpatient databases have confirmed short- and long-term mortality outcomes obtained from

    Injury of skeletal abdominal muscle wall is a common medical condition and implantation of synthetic or biological material is a procedure to repair musculofascial defects. We proposed to characterize the dynamics of inflammatory cell recruitment, newly formed blood vessels, cytokine production and fibrogenesis in the abdominal skeletal muscle in response to polyether-polyurethane sponge implants in mice. At 2, 4, 7 and 10days after implantation the muscle tissue underneath the sponge matrix was removed for the assessment of the angiogenic response (hemoglobin content, vascular endothelial growth factor and morphometric analysis of the number of vessels) and inflammation (myeloperoxidase and n-acethyl-B-d-glucosaminidase activities, cytokines). In addition, muscle fibrogenesis was determined by the levels of TGF-β1 and collagen deposition. Hemoglobin content, wash out rate of sodium fluorescein (indicative of blood flow) and the number of vessels increased in the abdominal muscle bearing the synthetic matrix in comparison with the intact muscle. Neutrophil recruitment peaked in the muscle at day 2, followed by macrophage accumulation at day 4 post-injury. The levels of the cytokines, VEGF, TNF-α, CCL-2/MCP-1 were higher in the injured muscle compared with the intact muscle and peaked soon after muscle injury (days 2 to 4). Collagen levels were higher in sponge-bearing muscle compared with the non-bearing tissue soon after injury (day 2). The implantation technique together with the inflammatory and vascular parameters used in this study revealed inflammatory, angiogenic and fibrogenic events and mechanisms associated with skeletal muscle responses to synthetic implanted materials.

    Abdominal intercostal hernia is an uncommon phenomenon, reported in few case reports and small case series. If left untreated, it can lead to strangulation and visceral ischemia. Prompt diagnosis and appropriate surgical intervention are thus critical to prevent resulting morbidity. We present a 50-year-old woman with a large abdominal intercostal hernia after an open nephrectomy. She underwent a successful robotic repair of the hernia with mesh placement. Through the presentation, we would like to raise awareness of intercostal hernia as a complication of open nephrectomy and significance of early diagnosis in avoiding potential morbidity. We also performed a review of literature especially focusing on acquired abdominal intercostal hernia secondary to prior surgery. Although intercostal hernias can be difficult to repair secondary to the size and location, adequate visualization and surgical planning are critical to successful repair.

    Colonic ischemia is a recognized complication of either open or endovascular abdominal aortic aneurysm repair. The clinical difficulty in establishing the diagnosis, the severity of this complication and the patient's poor physiological status may lead to a fatal outcome. We presented a case of ischemic colitis in a patient with patent hypogastric arteries that occurred after an endovascular abdominal aortic aneurysm repair as well as a review of the available literature. The patient's preoperative, intraoperative and postoperative data were recorded. A thorough search through the Google data and Medline to review similar cases or any analyses that referred to ischemic colitis after endovascular abdominal aneurysm repair was conducted. A 76-year-old male was admitted to our department for an elective endovascular repair of an 8 cm in diameter abdominal aortic aneurysm. A Zenith bifurcation graft was implanted. The whole procedure was uneventful and the final angiogram showed an accurate deployment of the endograft without endoleaks and patency of both hypogastric arteries. During the 1st postoperative day, the patient developed symptoms of acute abdomen in combination with metabolic acidosis and oliguria. He underwent an exploratory laparotomy, which revealed necrosis of the sig-moid. A Hartmann's procedure was performed;the patient was transferred to the intensive care unit where he deceased after 24 h. Postoperative ischemic colitis has been described after open abdominal aneurysm repair. The description of this complication has been reported since the early phase of endovascular abdominal aneurysm repair development with a current incidence of 1.5%–3.0%. Possible mechanisms that may contribute to ischemic colitis in spite of the presence of patent hypogastric arteries include athe-roembolization, shock, vasopressive drugs and inferior mesenteric artery occlusion.

    Current extracellular matrix (ECM) derived scaffolds offer promising regenerative responses in many settings, however in some applications there may be a desire for more robust and long lasting mechanical properties. A biohybrid composite material that offers both strength and bioactivity for optimal healing towards native tissue behavior may offer a solution to this problem. A regionally distinct biocomposite scaffold composed of a biodegradable elastomer (poly(ester urethane)urea) and porcine dermal ECM gel was generated to meet this need by a concurrent polymer electrospinning/ECM gel electrospraying technique where the electrosprayed component was varied temporally during the processing. A sandwich structure was achieved with polymer fiber rich upper and lower layers for structural support and an ECM-rich inner layer to encourage cell ingrowth. Increasing the upper and lower layer fiber content predictably increased tensile strength. In a rat full thickness abdominal wall defect model, the sandwich scaffold design maintained its thickness whereas control biohybrid scaffolds lacking the upper and lower fiber-rich regions failed at 8 weeks. Sandwich scaffold implants also showed higher collagen content 4 and 8 weeks after implantation, exhibited an increased M2 macrophage phenotype response at later times and developed biaxial mechanical properties better approximating native tissue. By employing a processing approach that creates a sheet-form scaffold with regionally distinct zones, it was possible to improve biological outcomes in body wall repair and provide the means for further tuning scaffold mechanical parameters when targeting other applications.

    y This article theoretically studies the influence of inhomogeneous abdominal walls on focused therapeutic ultrasound based on the phase screen model. An inhomogeneous tissue is considered as a combination of a homogeneous medium and a phase aberration screen. Variations of acoustic parameters such as peak positive pressure, peak negative pressure, and acoustic intensity are discussed with respect to the phase screen statistics of human abdominal walls. Results indicate that the abdominal wall can result in energy loss of the sound in the focal plane. For a typical human abdominal wall with correlation length of 7.9 mm and variance of 0.36, the peak acoustic intensity radiated from a 1 MHz transmitter with a radius of 30 mm can be reduced by about 14% at the focal plane.

    The abdominal wall is a composite of muscles that are important for the mechanical stability of the spine and pelvis. Tremendous clinical attention is given to these muscles, yet little is known about how they function in isolation or how they interact with one another. Given the morphological, vascular, and innervation complexities associated with these muscles and their proximity to the internal organs, an appropriate animal model is important for understanding their physiological and mechanical significance during function. To determine the extent to which the rat abdominal wall resembles that of human, 10 adult male Sprague-Dawley rats were killed and formalin-fixed for architectural and morphological analyses of the four abdominal wall muscles (rectus abdominis, external oblique, internal oblique, and transversus abdominis). Physiological cross-sectional areas and optimal fascicle lengths demonstrated a pattern that was similar to human abdominal wall muscles. In addition, sarcomere lengths measured in the neutral spine posture were similar to human in their relation to optimal sarcomere length. These data indicate that the force-generating and length change capabilities of these muscles, relative to one another, are similar in rat and human. Finally, the fiber lines of action of each abdominal muscle were similar to human over most of the abdominal wall. The main exception was in the lower abdominal region (inferior to the pelvic crest), where the external oblique becomes aponeurotic in human but continues as muscle fibers into its pelvic insertion in the rat. We conclude that, based on the morphology and architecture of the abdominal wall muscles, the adult male Sprague-Dawley rat is a good candidate for a model representation of human, particularly in the middle and upper abdominal wall regions.

    @@ Abdominal aortic aneurysm (AAA) has a high propensity to rupture. Repair of AAA by conventional surgical replacement with a graft has been the standard of treatment since the mid 1960s.Because of advances in surgical, anaesthetic and intensive care techniques, the outcome of elective open AAA repair has improved constantly. However,with the improvement of endovascular techniques,the role of open repair is being challenged.1 More and more stents are being deployed in patients because of their less invasive characteristics.2 We reviewed our ten years of experience with elective open AAA repair and recent papers about endoluminal and open repair for AAA to discuss status and future of open repair for AAA in China.

    Full Text Available Aim. The aim of the present study was to perform MRI in patients after ventral hernia mesh repair, in order to evaluate MRI’s ability to detect intra-abdominal adhesions. Materials and Methods. Single-center long term follow-up study of 155 patients operated for ventral hernia with laparoscopic (LVHR or open mesh repair (OVHR, including analyzing medical records, clinical investigation with patient-reported pain (VAS-scale, and MRI. MRI was performed in 124 patients: 114 patients (74% after follow-up, and 10 patients referred for late complaints after ventral mesh repair. To verify the MRI-diagnosis of adhesions, laparoscopy was performed after MRI in a cohort of 20 patients. Results. MRI detected adhesions between bowel and abdominal wall/mesh in 60% of the patients and mesh shrinkage in 20–50%. Adhesions were demonstrated to all types of meshes after both LVHR and OVHR with a sensitivity of 70%, specificity of 75%, positive predictive value of 78%, and negative predictive value of 67%. Independent predictors for formation of adhesions were mesh area as determined by MRI and Charlson index. The presence of adhesions was not associated with more pain. Conclusion. MRI can detect adhesions between bowel and abdominal wall in a fair reliable way. Adhesions are formed both after open and laparoscopic hernia mesh repair and are not associated with chronic pain.

    Abdominal aortic aneurysm complicated by a horseshoe kidney (HSK, fused kidney) represents a unique challenge for repair. Renal arteries arising from the aneurysmal aorta can further complicate intervention. Reports exist describing the repair of these complex anatomies using fenestrated endografts, hybrid open repairs (debranching), and open aneurysmorrhaphy with preservation of renal circulation. We describe an extra-anatomic, fully endovascular repair of an abdominal aortic aneurysm with a HSK partially supplied by a renal artery arising from the aneurysm. We successfully applied aortouni-iliac endografting, femorofemoral bypass, and retrograde renal artery perfusion via the contralateral femoral artery to exclude the abdominal aortic aneurysm and preserve circulation to the HSK.

    Full Text Available Desmoid tumors (also called desmoids fibromatosis are rare slow growing benign and musculoaponeurotic tumors. Although these tumors have a propensity to invade surrounding tissues, they are not malignant. These tumors are associated with women of fertile age, especially during and after pregnancy. We report a young female patient with a giant desmoid tumor of the anterior abdominal wall who underwent primary resection. The patient had no history of an earlier abdominal surgery. Preoperative evaluation included abdominal ultrasound, computed tomography, and magnetic resonance imaging. The histology revealed a desmoid tumor. Primary surgical resection with immediate reconstruction of abdominal defect is the best management of this rarity. To the best of our knowledge and PubMed search, this is the first case ever reported in the medical literature of such a giant desmoid tumor arising from anterior abdominal wall weighing 6.5 kg treated surgically with successful outcome.

    We retrospectively reviewed the computed tomographic CT examinations of 15 cases of abdominal wall hernia due to abdominal trauma; 13 patients had been injured in motor vehicle accidents (11 of those were belted in). All hernias were correctly identified on CT and confirmed intraoperatively. Traumatic abdominal wall hernia proved an important indicator of associated visceral injury, especially to the bowel (n = 6) and mesentery (n = 10). Careful review of the bowel and mesentery should thus be undertaken when disruption of the abdominal wall is documented. Radiologists should be aware, however, that CT findings may correlate poorly with severity of injury in these areas. In these instances, close clinical correlation and, sometimes, rescanning may be necessary. (author)

    Proteus syndrome is an extremely rare congenital disorder that produces multifocal overgrowth of tissue. This report presents a surgical case of a large lipoma in the abdominal wall of a patient with Proteus syndrome. She was diagnosed with Proteus syndrome based on certain diagnostic criteria. The neoplasm increased in size gradually, producing hemihypertrophy of her left lower extremity and trunk, and spread to her retroperitoneum and her left abdominal wall. She experienced gradually progressive constipation, nausea, vomiting, and abdominal pain. Computed tomography (CT) of the abdomen demonstrated a large mass in the subcutaneous adipose tissue of the left lower abdominal wall which measured 12 cm x 8 cm x 6 cm in diameter and encased the left colon. This mass in the abdominal wall was excised. The weight of the excised mass was 1550 g. The histopathological diagnosis of this mass was lipoma. After surgery, the encasement of the left colon was improved, and the patient was able to move her bowels twice per day. The excision of the large lipoma in the abdominal wall contributed to the improved bowel passage in this patient with Proteus syndrome.

    Aneurysm size changes form the basis of the follow-up after endovascular abdominal aortic aneurysm repair, because aneurysm growth increases rupture risk. Aneurysm growth can be caused by endoleak (leakage of blood in the aneurysm sac). Therefore, accurate endoleak detection is important in growing

    A most important factor for human occupied habitats in space is to ensure that the pressurized habitat does not lose pressure catastrophically by the penetration of space debris or micrometeorites through the wall and into the pressurized space. Regenerative self repairing composites used for the space station habitat to prevent loss of pressure was demonstrated in tests The wall sample had ambient pressurized on one side with vacuum on the other, then was punctured all the way through; the pressure reading went from -26 inches of mercury to -26 inches and stayed there indefinitely. There was no loss of pressure! This will be a game changer for space habitat design. This represents a proposed test bed experimental effort on the International Space Station for self repairing regenerative walls of pressurized habitats, supported by significant puncture over vacuum and puncture testing performed to date, which will provide NASA with an innovative new light weight multi-hit superior Astronaut Protective Wall solution for pressurized space habitats.

    Severe ulcerative colitis can be associated with bowel perforation. Bowel perforation rarely leads on to abdominal wall and scrotal wall emphysema. Bowel perforation in such cases can be spontaneous or iatrogenic (colonoscopy-related). We report a rare scenario where a patient presented with abdominal wall and scrotal emphysema after topical corticosteroid enema-induced traumatic rectal perforation. Topical corticosteroids were stopped immediately after identification of rectal perforation. The patient was managed conservatively with intravenous antibiotics. With this report we intend to sensitise clinicians and topical enema manufacturers regarding this rare complication.

    We report a case of resection of malignant fibrous histiocytoma (MFH) via combined thoracic and abdominal wall incision reconstructed using GORE DUALMESH. A 60-year-old woman underwent resection of a left lower chest wall tumor. Since the tumor infiltrated into the diaphragm, a part of the left diaphragm and left upper abdominal wall were resected together. The left chest was closed by suturing the diaphragm to the ribs. The resected area of the thoracic and abdominal wall was 12×12 cm and was reconstructed with GORE DUALMESH. She received adjuvant radiotherapy as the tumor cells were detected in the surgical margin of the diaphragm. The patient has remained well without signs of recurrence for 10 months after the operation.

    Tuberculous aneurysm of the aorta is exceedingly rare. To date, the standard therapy for mycotic aneurysm of the abdominal aorta has been surgery involving in-situ graft placement or extra-anatomic bypass surgery followed by effective anti-tuberculous medication. Only recently has the use of a stent graft in the treatment of tuberculous aortic aneurysm been described in the literature. We report two cases in which a tuberculous aneurysm of the abdominal aorta was successfully repaired using endovascular stent grafts. One case involved is a 42-year-old woman with a large suprarenal abdominal aortic aneurysm and a right psoas abscess, and the other, a 41-year-old man in whom an abdominal aortic aneurysm ruptured during surgical drainage of a psoas abscess.

    Full Text Available Abstract Abdominal wall hematoma is a rare and life-threatening complication after carotid artery stenting (CAS, but it can occur when activated clotting time is prolonged. We report a right lateral abdominal wall hematoma caused by rupture of the superficial circumflex iliac artery after CAS in a 72-year-old man with severe stenosis of the origin of the right internal carotid artery. We performed CAS for the targeted lesion while activated clotting time exceeded 300 seconds. After 2 hours, he complained of right lateral abdominal pain. Abdominal computed tomography revealed an extensive hematoma in the right lateral abdominal wall. Activated clotting time was 180 seconds at this point. Seven hours later, he developed hypotension and hemoglobin level dropped to 11.3 g/dl. Subsequent computed tomography showed enlargement of the hematoma. Emergent selective angiography of the external iliac artery revealed active bleeding from the right superficial circumflex iliac artery. Transcatheter arterial embolization with Gelfoam and microcoils was performed successfully. With more CAS procedures being performed, it is important for endovascular surgeons and radiologists to consider the possibility of abdominal wall hematoma in this situation.

    Throughout life, inguinal hernia develops in approximately every fourth man, some of whom develop multiple hernias. If patients at risk of developing multiple hernias could be identified by a serologic biomarker, treatment might be able to be tailored and improved. Evidence suggests that abdominal wall hernia formation is associated with altered collagen metabolism. The aim of this study was to evaluate biomarkers for type IV and V collagen turnover in patients with multiple hernias and control subjects without hernia. Venous blood was collected from 88 men (mean age, 62 years) with a history of more than 3 hernia repairs and 86, age-matched men without hernias. Biomarkers for synthesis of collagen type IV (P4NP) and type V (P5CP) as well as breakdown (C4M and C5M) were measured in serum by validated, solid-phase, competitive assays. Collagen turnover was indicated by the ratio between the biomarker for synthesis and breakdown. Type IV collagen turnover was 1.4-fold increased in patients with multiple hernias compared to control subjects (P hernias exhibit increased turnover of type IV collagen and a decreased turnover of type V collagen, demonstrating systemically altered collagen turnover. Biomarkers for type V collagen turnover may be used to identify patients at risk for or with multiple hernias. Copyright © 2016 Elsevier Inc. All rights reserved.

    Abdominal wall endometriosis (AWE) is a rare but easily treated cause of pain in women, especially those who have undergone cesarean deliveries. This article reviews the diagnosis and management of AWE, a condition that generally develops after surgery but may arise spontaneously. We present a systematic review of the existing literature on AWE, as well as our clinical recommendations for medical and surgical management. We searched PubMed and other databases using the search criteria "abdominal wall endometriosis," "abdominal wall endometriomas," and "abdominal wall mass." The references of those articles were then reviewed, and additional publications were evaluated. Many case reports and case series have been published describing AWE. The overall quality of evidence is poor due to the lack of prospective studies and heterogeneous descriptions of AWE lesions and treatment options. Based on the available literature, it appears that AWE may arise spontaneously but is generally associated with prior pelvic surgery. Abdominal wall endometriosis can be diagnosed with a careful history and physical examination. Imaging including ultrasound and magnetic resonance imaging can assist with localization of the lesions, and aid in surgical excision and management. Lesions that have been removed in their entirety are unlikely to reoccur. Although limited, the body of literature describing management of AWE suggests that it can be successfully treated in most patients with careful surgical planning.

    Full Text Available Tuberculosis is considered as ubiquitous disease as it involves any organ, but primary involvement of abdominal muscles is very rare. In most cases, the muscle involvement is secondary and is caused by either hematogenous route or direct inoculation from a tuberculous abdominal lymph node or extension from underlying tubercular synovitis and osteomyelitis. Autopsy studies have shown abdominal wall involvement in less than 1% of patients who died of tuberculosis. Antitubercular therapy is main form of management. Surgical intervention is always secondary in the form of either sonography or computerized tomography-guided aspiration or open drainage which is usually reserved for patients in whom medical treatment has failed. A case is hereby reported about primary tubercular anterior abdominal wall abscess without any evidence of pulmonary, skeletal or gastrointestinal tuberculosis in an apparently healthy individual with any past history of contact or previous antituberculosis therapy.

    In a computed tomography (CT) scan, fat deposition in the urinary bladder wall is seen as a linear hypoattenuating band surrounded by soft tissue density. It is uncommon, but is often seen in normal cases. However, there is no report of fat deposition in the urinary bladder wall in Korea. The authors encountered a 62-year-old male patient who showed an incidental hypoattenuating band in the urinary bladder wall on abdominal CT. The patient showed no clinical signs related to fat deposition in the urinary bladder wall. When the patient's previous abdominal CT was retrospectively reviewed, the same CT finding was seen. This linear hypoattenuating band within the urinary bladder wall should be considered as a normal CT finding, although it is uncommon.

    Defects of the ventral body wall are prevalent birth anomalies marked by deficiencies in body wall closure, hypoplasia of the abdominal musculature and multiple malformations across a gamut of organs. However, the mechanisms underlying ventral body wall defects remain elusive. Here, we investigated the role of Wnt signaling in ventral body wall development by inactivating Wls or β-catenin in murine abdominal ectoderm. The loss of Wls in the ventral epithelium, which blocks the secretion of Wnt proteins, resulted in dysgenesis of ventral musculature and genito-urinary tract during embryonic development. Molecular analyses revealed that the dermis and myogenic differentiation in the underlying mesenchymal progenitor cells was perturbed by the loss of ectodermal Wls. The activity of the Wnt-Pitx2 axis was impaired in the ventral mesenchyme of the mutant body wall, which partially accounted for the defects in ventral musculature formation. In contrast, epithelial depletion of β-catenin or Wnt5a did not resemble the body wall defects in the ectodermal Wls mutant. These findings indicate that ectodermal Wnt signaling instructs the underlying mesodermal specification and abdominal musculature formation during ventral body wall development, adding evidence to the theory that ectoderm-mesenchyme signaling is a potential unifying mechanism for the origin of ventral body wall defects.

    Abdominal wall metastasis from urothelial cancer is extremely rare and very few such cases have been reported in the literature. As such the treatment protocols are not so well defined. We present an interesting case of a 65-year-old male patient, known case of chronic kidney disease, who presented with a large, fungating infraumbilical mass 8 months postradical cystectomy. The mass involved full thickness anterior abdominal wall and small bowel including the ileal conduit. Wide excision of the mass along with adhered bowel loops and partial excision of the ileal conduit with right ureteric reimplant was performed. The large defect in the anterior abdominal wall was closed using a mesh (permanent with a bioresorbable coating inside) and myocutaneous thigh flap. The histopathological examination of the excised mass was consistent with secondary from the urothelial tumor.

    2012-07-01

    Full Text Available Extrauterine or extraintestinal leiomyomas are extremely uncommon especially in the pre-peritoneal area or within the anterior abdominal wall muscles. These tumors have been ascribed to intraoperative seeding during resection of a fibroid or a leiomyoma of gut, to exogenous hormone replacement therapy or a major derangement of glucose and/or lipid metabolism. So far, there is no published report of de novo origin of anterior abdominal wall pure leiomyoma in the literature. The author herein reports a case of perimenopausal multiparous woman without any listing of previous gynecological surgery or hormone therapy who presented with a large pre-peritoneal intramuscular leiomyoma of the anterior abdominal wall. The patient underwent complete primary resection with amelioration of her symptoms.

    Full Text Available The authors present a retrospective study of 60 patients with abdominal dystrophies, both with and without hernias, operated on in the period between 01 June 1994 and 30 January 1996. Their average age was 47 years. The incision at hernia itself and the dystrophic abdomen were the principal objects of the study. The authors show the importance of abdominal dermolipectomy for the complete recovery of the patient as well as demonstrate how it facilitates the technical manipulation of hernias. The technique of bilateral, longitudinal peritonio-aponeurotic transposition {the technique of Alcíno Lázaro da Silva was used for large incisional hernias. A variation of this technique, for hernias with a hernial ring of up to 10 cm, is proposed by the authors, which consists in the closing of the ring and the reinforcement of the suture with the hernial sac. A revision is made of the results of these procedures realized in isolation and accompanied with abdominal dermolipectomy. Forty-nine recovered without complications (81.66%, three relapsed (5%, one necrosis of the midline with respiratory failure (1.67%, one little stitch gap (1,67%, two umbilical stenosis (3,33%, two wound abscess (3.33%, one cutaneous fistula (1,67% and one death from pulmonary embolism (1.66%.

    Proteus syndrome is an extremely rare congenital disorder that produces multifocal overgrowth tissue. This report presents a surgical case of a large lipoma in the abdominal wall of a patient with Proteus syndrome. She was diagnosed with Proteus syndrome based on certain diagnostic criteria. The neoplasm increased in size gradually, producing hemihypertrophy of her left lower extremity and trunk, and spread to her retroperitoneum and her left abdominal wall. She experienced gradually progressive constipation,nausea, vomiting, and abdominal pain. Computed tomography (CT) of the abdomen demonstrated large mass in the subcutaneous adipose tissue of the cm x 6 cm in diameter and encased the left colon. This mass in the abdominal wall was excised. The weight of the excised mass was 1550 g. The histopathological diagnosis of this mass was lipoma. After surgery, the encasement of the left colon was improved, and the patient was able to move her bowels twice per day. The excision of the large lipoma in the abdominal wall contributed to the improved bowel passage in this patient with Proteus syndrome.

    2004-03-01

    The purpose of this retrospective, single-institution study is to describe a 4-year experience of examining early and late clinical outcomes after endovascular repair of abdominal aortic aneurysm (AAA). Between October 1998 and January 2003, 455 patients were submitted for AAA treatment, of whom 269 underwent open repair and 186 were treated with an endovascular procedure. All endovascular-treated patients underwent preoperative arteriography, contrast enhanced CT scanning or spiral-CT to define the morphological characteristics of the aneurysm, including precise diameter and length measurements. Technical success was achieved in 182 (98%) of the endovascular procedures, as intraoperative conversions to open repair and/or aborted procedures occurred in four patients. The perioperative (30-day) mortality rate was 1% (two patients). During the follow-up period (9-60 months) CT, duplex ultrasound scanning and plain abdominal X-ray evaluation were performed at 3, 6, 12 months, and annually thereafter. Type I endoleak occurred in 12 patients (6.6%), required a further endovascular procedure (11) or late conversion to open repair (1). Type II endoleak occurred in five patients (3%). In our clinical experience the endovascular repair of AAA is a safe and effective technique with good mid-term results in patients at standard and high risk.

    Systemic infectious complications following adenotonsillectomy are exceedingly rare. We describe an otherwise healthy 2-year-old patient who developed group A beta-hemolytic Streptococcus sepsis and presumptive scarlet fever 3 days after an uncomplicated adenotonsillectomy. After resolution of fever, rash, and discharge home on antibiotics, the patient returned on postoperative day 10 with an abdominal wall abscess. This is the first reported case of an abdominal wall abscess as a complication of adenotonsillectomy. This case demonstrates that an awareness of unexpected infectious complications of adenotonsillectomy should be a part of postsurgical management. Laryngoscope, 125:1230-1232, 2015.

    We report a case of a previously healthy woman after an uneventful caesarean section who developed polymicrobial necrotizing fasciitis. She was given a non-steroidal anti-inflamatory drug (NSAID) after her delivery. Her post-delivery course was complicated by septic shock, and required multiple debridements before abdominal reconstruction. This case describes the increased risk of necrotizing fasciitis with NSAID use. Unusual were the organisms causing the polymicrobial necrotizing fasciitis: Staphylococcus aureus, Enterobacter agglomerans, Acinetobacter baumannii, and two strains of Enterobacter cloacae.

    The value of emergency endovascular aneurysm repair (EVAR) in the setting of ruptured abdominal aortic aneurysm remains controversial owing to differing results. However, interpretation of published results remains difficult as there is a lack of generally accepted protocols or standard operating procedures. Furthermore, such protocols and standard operating procedures often are reported incompletely or not at all, thereby making interpretation of results difficult. We herein report our integrated logistic system for the endovascular treatment of ruptured abdominal aortic aneurysms. Important components of this system are prehospital logistics, in-hospital treatment logistics, and aftercare. Further studies should include details about all of these components, and a description of these logistic components must be included in all future studies of emergency EVAR for ruptured abdominal aortic aneurysms.

    Background Thresholds for repair of abdominal aortic aneurysms vary considerably among countries. Methods We examined differences between England and the United States in the frequency of aneurysm repair, the mean aneurysm diameter at the time of the procedure, and rates of aneurysm rupture and aneurysm-related death. Data on the frequency of repair of intact (nonruptured) abdominal aortic aneurysms, in-hospital mortality among patients who had undergone aneurysm repair, and rates of aneurysm rupture during the period from 2005 through 2012 were extracted from the Hospital Episode Statistics database in England and the U.S. Nationwide Inpatient Sample. Data on the aneurysm diameter at the time of repair were extracted from the U.K. National Vascular Registry (2014 data) and from the U.S. National Surgical Quality Improvement Program (2013 data). Aneurysm-related mortality during the period from 2005 through 2012 was determined from data obtained from the Centers for Disease Control and Prevention and the U.K. Office of National Statistics. Data were adjusted with the use of direct standardization or conditional logistic regression for differences between England and the United States with respect to population age and sex. Results During the period from 2005 through 2012, a total of 29,300 patients in England and 278,921 patients in the United States underwent repair of intact abdominal aortic aneurysms. Aneurysm repair was less common in England than in the United States (odds ratio, 0.49; 95% confidence interval [CI], 0.48 to 0.49; Paneurysm-related death was more common in England than in the United States (odds ratio, 3.60; 95% CI, 3.55 to 3.64; Paneurysm rupture occurred more frequently in England than in the United States (odds ratio, 2.23; 95% CI, 2.19 to 2.27; Paneurysm diameter at the time of repair was larger in England (63.7 mm vs. 58.3 mm, Pabdominal aortic aneurysms and a larger mean aneurysm diameter at the time of repair in England than in the United

  17. "EFFECTIVENESS OF ABDOMINAL WALL ELEVATOR IN REDUCING INTRA-ABDOMINAL PRESSURE AND CO2 VOLUME DURING LAPAROSCOPIC CHOLECYSTECTOMY"

    Full Text Available Since CO2 pneumoperitoneum is the dominant method of laparoscopic exposure due to facility and good view, its physiologic effects are most relevant to the surgeons. CO2 pneumoperitoneum may affects hemodynamics by increased intra-abdominal pressure (IAP and the physiologic effects of absorbed CO2. The adverse effects of both mechanisms relate directly to the duration of the pneumoperitoneum and the elevation of IAP. Gasless laparoscopy involves obtaining exposure for laparoscopy by placing an internal retracting device through a small incision and lifting the anterior abdominal wall. We designed and made a mechanical wall elevator and used it in 24 patients, compared with a control group (52 cases using a conventional laparoscopic cholecystectomy. A prospective trial was undertaken in Sina Hospital, Tehran University of Medical Sciences from 1998 to 2000. The patients were assigned randomly to two groups. There was a significant decrease in IAP and CO2 consumption in the group using mechanical wall elevator as compared to conventional laparoscopic cholecystectomy, (mean IAP of 3.5 mmHg compared to 11.4 mmHg in the control group, mean CO2 volume 17 liters compared to 73 liters in the control group. We recommend this semigasless method in laparoscopy due to safety in performance and significant reduction in IAP through the surgery. This method provides a satisfactory view and easy performance without any increase in time or complications. The hospital stay and costs did not increase.

    The performance of hernia treatment could benefit from more extensive knowledge of the mechanical behavior of the abdominal wall in a healthy state. To supply this knowledge, the antero-lateral abdominal wall was characterized in vivo on 11 healthy volunteers during 4 activities: rest, pullback loading, abdominal breathing and the "Valsalva maneuver". The elasticity of the abdominal muscles (rectus abdominis, obliquus externus, obliquus internus and transversus abdominis) was assessed using ultrasound shear wave elastography. In addition, the abdomen was subjected to a low external load at three locations: on the midline (linea alba), on the rectus abdominis region and on lateral muscles region in order to evaluate the local stiffness of the abdomen, at rest and during "Valsalva maneuver". The results showed that the "Valsalva maneuver" leads to a statistically significant increase of the muscle shear modulus compared to the other activities. This study also showed that the local stiffness of the abdomen was related to the activity. At rest, a significant difference has been observed between the anterior (0.5N/mm) and the lateral abdomen locations (1N/mm). Then, during the Valsalva maneuver, the local stiffness values were similar for all locations (ranging from 1.6 to 2.2N/mm). This work focuses on the in vivo characterization of the mechanical response of the human abdominal wall and abdomen during several activities. In the future, this protocol could be helpful for investigation on herniated patients.

    Full Text Available Aim. The aim of this study is to introduce a new technique, anterior vaginal wall darn (AVWD, which has not been used before to repair the anterior vaginal wall prolapse, a common problem among women. Materials and Methods. Forty-five women suffering from anterior vaginal wall prolapse were operated on with a new technique. The anterior vaginal wall was detached by sharp and blunt dissection via an incision beginning from the 1 cm proximal aspect of the external meatus extending to the vaginal apex, and the space between the tissues that attach the lateral walls of the vagina to the arcus tendineus fascia pelvis (ATFP was then darned. Preoperation and early postoperation evaluations of the patients were conducted and summarized. Results. Data were collected six months after operation. Cough stress test (CST, Pelvic Organ Prolapse Quantification (POP-Q evaluation, Incontinence Impact Questionnaire (IIQ-7, and Urogenital Distress Inventory (UDI-6 scores indicated recovery. According to the early postoperation results, all patients were satisfied with the operation. No vaginal mucosal erosion or any other complications were detected. Conclusion. In this initial series, our short-term results suggested that patients with grade II-III anterior vaginal wall prolapsus might be treated successfully with the AVWD method.

    Aortic calcification and thrombus have been postulated to worsen outcome following endovascular abdominal aortic aneurysm repair (EVAR). The purpose of this study was to assess the association of abdominal aortic aneurysm (AAA) calcification and thrombus volume with outcome following EVAR using a reproducible, quantifiable computed tomography (CT) assessment protocol. Patients with elective EVAR performed between January 2002 and 2012 at the Townsville Hospital, Mater Private Hospital (Townsville) and Royal Brisbane and Women's Hospital (RBWH) were included if preoperative CTAs were available for analysis. AAA calcification and thrombus volume were measured using a semiautomated workstation protocol. Outcomes were assessed in terms of clinical failure, endoleak (type I, type II) and reintervention. Univariate and multivariate analyses were performed. Median follow-up was 1.7 years and the interquartile range 1.0-3.8 years. One hundred thirty-four patients undergoing elective EVAR were included in the study. Rates of primary clinical success and freedom from reintervention were 82.8 % and 88.9 % at the 24-month follow-up. AAA calcification and thrombus volume were not associated with clinical failure, type I endoleak, type II endoleak or reintervention. AAA calcification and thrombus volume were not associated with poorer outcome after EVAR in this study. (orig.)

    We report two cases of isolated abdominal wall actinomycosis and review 18 previously reported cases to further characterize the clinical findings and the therapeutic management of this syndrome. This diagnosis would be advocated in patients with a palpable abdominal mass of subacute appearance with a previous history of digestive medical illness, diabetes, abdominal surgery, or prolonged IUD use. In contrast with other actinomycosis locations, remarkable data were a more elevated mean age of patients; a female predominance; a prevalent location of mass in abdominal lower left quadrant; and a shorter duration of symptomatology before to diagnosis. The CT is the first choice for imaging study and percutaneous needle aspiration would be recommended for definite diagnosis. The long-term antibiotic therapy, with or without percutaneous drainage, is the first treatment choice because is very effective and made unnecessary a more invasive surgical management. The prognosis is excellent with adequated treatment.

    Summary: Symptomatic heterotopic ossification of abdominal surgical incisions is a rare occurrence. We present a 67-year-old man with severe discomfort caused by heterotopic ossification extending from the xiphoid to the umbilicus. The patient underwent an abdominal aortic aneurysm repair 3 years before our treatment. A 13 × 3.5 cm ossified lesion was excised. The resulting midline defect was closed using component separation and inlay Strattice. Tension-free midline adaptation of the recti muscles was achieved. A computed tomography scan of the abdomen 6 months after the surgery showed no recurrence or hernias. Heterotopic ossification in symptomatic patients has previously been treated with excision and primary closure. We believe that tension-free repair is important to prevent recurrence. Acellular dermal matrix may add to this effect and also compartmentalize the process. PMID:27536495

    Full Text Available Gastrointestinal tract complications after abdominal aortic aneurysm (AAA repair are well known. The reported frequency ranges from 6.6% to 21%. However, the incidence of duodenal obstruction following AAA has probably been underestimated. This report concerns a 78-year-old male who was admitted for elective repair of an infrarenal AAA. On the ninth postoperative day, the patient presented with large quantities of bile-stained vomitus despite passing flatus per rectum. Metoclopramide and ranitidine were given under the initial impression of paralytic ileus. However, the upper gastrointestinal obstruction persisted, and on day 12, computerized tomography (CT revealed marked distension of the gastric tube and duodenum, down to the level of the third portion, with abrupt change of caliber at the point of the superior mesenteric artery (SMA. SMA syndrome was diagnosed. After nasogastric tube aspiration, parenteral nutrition, and 11 days of conservative treatment, abdominal CT and upper gastrointestinal series showed no apparent duodenal obstruction. The patient was discharged on the 29th postoperative day; follow-up abdominal CT 4 months later was unremarkable.

    As an alternative to surgery, endovascular therapy with stent grafts has become the second main treatment option for infrarenal abdominal aortic aneurysms. Unlike surgery, endovascular treatment with stent grafts is also applicable in patients unfit for open repair. Despite current improvements in endovascular repair devices, significant anatomic barriers still exclude this technique for a large number of patients. Computed tomography, magnetic resonance imaging, and ultrasound are essential for diagnostics, preintervention planning, and postintervention follow-up of abdominal aneurysms treated with stent grafts. This review covers etiology, pathology, and diagnostic aspects. Materials and methods for endovascular treatment of abdominal aortic aneurysms are presented in detail, and clinical results and complications are discussed. (orig.) [German] Die endovaskulaere Therapie des infrarenalen Bauchaortenaneurysmas hat sich als Alternative zur offenen chirurgischen Versorgung etabliert.

    Full Text Available Abstract Backround Sigmoid colon cancer metachronous metastases commonly occur in the liver and lungs with sporadic reports also to the spleen, stomach, thyroid gland, abdominal wall and upper urinary tract. This is a rare case of metachronous metastases invading the mesorectum and the abdominal wall. Case presentation A 72-year-old female underwent sigmoidectomy for stage I (T2N0 M0 sigmoid colon cancer in May 2008. In June 2009, an abdominal computed tomography scan revealed a tumor 2 cm in size at the lower anterior mesorectum and a second mass 2 cm in size at the anterior abdominal wall midline. Total colonoscopy showed no mucosal lesion. The serum carcinoembryonic antigen level was normal. A biopsy of the mesorectum tumor showed similar histologic characteristics with the primary tumor. Since no other site of recurrence was identified, an abdominoperineal resection was attempted. During the operation and after the removal of the incision recurrence, sinus bradycardia and signs of myocardial ischemia were noticed. A loop transverse colostomy was immediately perfomed and the operation was terminated. Postoperative cardiologic examination revealed an acute myocardium infract. Chemo-radiation of the mesorectum tumor and re-evaluation for surgical excision was decided. Conclusion Metachronous metastasis of the mesorectum from sigmoid colon cancer is extremely rare. Although patterns of lymphatic spread from rectal cancer to sigmoid colon have recently been demonstrated, there is no evidence of metachronous mesorectum invasion from sigmoid colon cancer. This could be the issue for future trials.

    Objectives The relationship between preoperative medical consultations and postoperative complications has not been extensively studied. Thus, we investigated the impact of preoperative consultation on postoperative morbidity following elective abdominal aortic aneurysm repair. Methods A retrospective review was conducted on 469 patients (mean age 72 years, 20% female) who underwent elective abdominal aortic aneurysm repair from June 2007 to July 2014. Data elements included detailed medical history, preoperative cardiology consultation, and postoperative complications. Primary outcomes included 30-day morbidity, consult-specific morbidity, and mortality. A bivariate probit regression model accounting for the endogeneity of binary preoperative medical consult and patient variability was estimated with a maximum likelihood function. Results Eighty patients had preoperative medical consults (85% cardiology); thus, our analysis focuses on the effect of cardiac-related preoperative consults. Hyperlipidemia, increased aneurysm size, and increased revised cardiac risk index increased likelihood of referral to cardiology preoperatively. Surgery type (endovascular versus open repair) was not significant in development of postoperative complications when controlling for revised cardiac risk index ( p = 0.295). After controlling for patient comorbidities, there was no difference in postoperative cardiac-related complications between patients who did and did not undergo cardiology consultation preoperatively ( p = 0.386). Conclusions When controlling for patient disease severity using revised cardiac risk index risk stratification, preoperative cardiology consultation is not associated with postoperative cardiac morbidity.

  13. Aortoenteric Fistula as a Complication of Open Reconstruction and Endovascular Repair of Abdominal Aorta

    Directory of Open Access Journals (Sweden)

    Marek Tagowski

    2014-01-01

    Full Text Available The paper intends to present a review of imaging characteristics of secondary aortoenteric fistula (AEF. Mechanical injury, infection, and adherence of a bowel segment to the aorta or aortic graft are major etiologic factors of AEF after open aortic repair. The pathogenesis of AEF formation after endovascular abdominal aortic repair is related to mechanical failure of the stent-graft, to stent graft infection, and to persistent pressurization of the aneurysmal sac. The major clinical manifestations of AEF comprise haematemesis, melaena, abdominal pain, sepsis, and fever. CT is the initial diagnostic modality of choice in a stable patient. However, the majority of reported CT appearances are not specific. In case of equivocal CT scans and clinical suspicion of AEF, scintigraphy, 67Ga citrate scans or 18F-FDG PET/CT is useful. Diagnostic accuracy of endoscopy in evaluation of AEF is low; nevertheless it allows to evaluate other than AEF etiologies of gastrointestinal bleeding. Without adequate therapy, AEF is lethal. Conventional surgical treatment is associated with high morbidity and mortality. The endovascular repair may be an option in hemodynamically unstable and high-risk surgical patients. We also illustrate an example of a secondary AEF with highly specific albeit rare radiologic picture from our institution.

    Reducing readmissions represents a unique opportunity to improve care and reduce health care costs and is the focus of major payers. A large number of surgical patients are readmitted to hospitals other than where the primary surgery was performed, resulting in clinical decisions that do not incorporate the primary surgeon and potentially alter outcomes. This study characterizes readmission to primary vs different hospitals after abdominal aortic aneurysm (AAA) repair and examines the implications with regard to mortality and cost. Patients who underwent open or endovascular aneurysm repair for AAA were identified from the Centers for Medicare and Medicaid Services Chronic Conditions Warehouse, a random 5% national sample of Medicare beneficiaries from 2005 to 2009. Outcomes for patients who underwent AAA repair and were readmitted within 30 days of initial discharge were compared based on readmission location (primary vs different hospital). A total of 885 patients underwent AAA repair and were readmitted within 30 days. Of these, 626 (70.7%) returned to the primary facility, and 259 (29.3%) returned to a different facility. Greater distance from patient residence to the primary hospital was the strongest predictor of readmission to a different facility. Patients living 50 to 100 miles from the primary hospital were more likely to be readmitted to a different hospital compared with patients living facility after AAA repair is common and occurs more frequently than for the overall Medicare population. Patients travelling a greater distance for AAA repair are more likely to return to different vs the primary hospital when further care is required. For AAA repair, quality healthcare may be achieved at marginally lower cost and with greater patient convenience for selected readmissions at hospitals other than where the initial procedure was performed.

    We present a unique experience with a patient who had undergone continuous ambulatory peritoneal dialysis (CAPD) after laparoscopic repair of ventral incisional hernia (LRVIH) with an expanded polytetrafluoroethylene (e-PTFE) mesh (DualMesh(®); WL Gore) and who later suffered from multiple episodes of CAPD-related peritonitis without any signs of mesh infection. A 48-year-old man with an open abdominal aortic reconstruction in 1994 for occlusive arterial disease presented with an incisional ventral hernia. He underwent LRVIH using an e-PTFE mesh of 30×20 cm. Postoperatively, he developed renal failure. For various reasons, the only therapeutic option was CAPD. A CAPD-catheter was implanted via laparoscopy, taking care not to compromise the mesh that was completely covered with neoperitoneum. After 3 months of uneventful CAPD, he developed a bacterial peritonitis. Antibiotic treatment failed and the CAPD-catheter was removed. The mesh was left in place and the patient recovered. Later on another CAPD-catheter was implanted via laparoscopy and used for 10 months. Again he developed peritonitis from which he recovered after catheter removal. Mesh was left in place and remained uninfected, probably protected from intra-abdominal bacteria by the neoperitoneum. The risk of secondary infection of an intra-abdominal mesh seems to diminish largely after neoperitonealization of the mesh. CAPD seems possible in a patient with an intra-abdominal mesh when it is covered with neoperitoneum.

Methods Retrospective study were carried out to 32 cases of abdominal wall bulge of which patients were accepted CT examination. The site and size of the bulge were evaluated, and postoperative CT examination was performed to evaluate the effect of the operation. Results Out of the 32 cases, 14 accepted surgical repair using synthetic mesh while the rest didn' t. CT scan demonstrated no facial defect or herniation of any intra-abdominal content in the bulge area, but the lateral abdominal wall musculature (external oblique, internal oblique, and transversus abdominal muscles) and/or rectus muscle on the bulge side appeared attenuated compared with the corresponding structures on the opposite side. The following CT scan check-up showed that the three layers of abdominal muscles on the bulge side appeared to be thicker compared with preoperative structures and the spaces between the three muscular layers emerged. And the mesh could be seen in some cases in CT scan. Conclusion CT scan is perfect in the diagnosis of the abdominal wall bulge and plays an important role in the evaluation of the patient situation, surgical technique and effectiveness of surgical repair.

    Full Text Available INTRODUCTION Abdominal aortic aneurysm can be repaired by elective procedure while asymptomatic, or immediately when it is complicated - mostly due to rupture. Treating abdominal aneurysm electively, before it becomes urgent, has medical and economical reason. Today, the first month mortality after elective operations of the abdominal aorta aneurysm is less than 3%; on the other hand, significant mortality (25%-70% has been recorded in patients operated immediately because of rupture of the abdominal aneurysm. In addition, the costs of elective surgical treatment are significantly lower. OBJECTIVE The objective of this study is to compare long-term survival of patients that underwent elective or immediate repair of abdominal aortic aneurysm (due to rupture, and to find out the factors influencing the long-term survival of these patients. MATERIAL AND METHODS Through retrospective review of prospectively collected data of the Institute for Cardiovascular Diseases of Clinical Center of Serbia, Belgrade, 56 patients that had elective surgery and 35 patients that underwent urgent operation due to rupture of abdominal aneurysm were followed up. Only the patients that survived 30 postoperative days were included in this review, and were followed up (ranging from 2 to 126 months. Electively operated patients were followed during 58.82 months on the average (range 7 to 122, and urgently operated were followed over 52.26 months (range 2 to 126. There was no significant difference of the length of postoperative follow-up between these two groups. RESULTS During this period, out of electively operated and immediately operated patients, 27 and 22 cases died, respectively. There was no significant difference (p>0,05a of long-term survival between these two groups. Obesity and early postoperative complications significantly decreased long-term survival of both electively and immediately operated patients. Graft infection, ventral hernia, aneurysm of

  18. Acute Testicular Ischemia following Endovascular Abdominal Aortic Aneurysm Repair Identified in the Emergency Department

    Full Text Available Endovascular aneurysm repair (EVAR is perhaps the most widely utilized surgical procedure for patients with large abdominal aortic aneurysms. This procedure is minimally invasive and reduces inpatient hospitalization requirements. The case involves a 72-year-old male who presented to the emergency department with right testicular ischemia two days following EVAR. Given the minimal inpatient hospitalization associated with this procedure, emergency physicians are likely to encounter associated complications. Ischemic and thromboembolic events following EVAR are extremely rare but require prompt vascular surgery intervention to minimize morbidity and mortality.

  19. An Update on the Inflammatory Response after Endovascular Repair for Abdominal Aortic Aneurysm

    2015-01-01

    Full Text Available Postimplantation syndrome (PIS is the clinical and biochemical expression of an inflammatory response following endovascular repair of an aortic aneurysm (EVAR. The goal of this review is to provide an update on the inflammatory response after endovascular repair of abdominal aortic aneurysm, discussing its causes and effects on the clinical outcome of the patient. PIS concerns nearly one-third of patients after EVAR. It is generally a benign condition, although in some patients it may negatively affect outcome. The different definitions and conclusions drawn from several studies reveal that PIS needs to be redefined with standardized diagnostic criteria. The type of the endograft’s material seems to play a role in the inflammatory response. Future studies should focus on a better understanding of the underlying pathophysiology, predictors, and risk factors as well as determining whether effective preventive strategies are necessary.

    An ideal prosthetic mesh for incisional hernia repair should mimic the anisotropic compliance of the abdominal wall, and at lower loads should exhibit higher distensibility without impairment of safety at higher loads. This study evaluated the biomechanical properties of six meshes in a rabbit model. New Zealand white rabbits were used for this study. Two meshes of the same brand (Ethicon Physiomesh™, Bard Composix(®) L/P, Gore Dualmesh(®), Bard Sepramesh(®), Ethicon Proceed(®) or Parietex™ Composite) were implanted into each animal for assessment of intra-abdominal hernia repair, with a total of ten meshes per group. Twelve weeks after implantation, the abdominal walls with ingrown meshes were harvested and examined biomechanically with a plunger test. The mesh-tissue compliance was evaluated by the forces exerted at given displacements and also described through a simple mathematical approximation. Abdominal wall samples were collected for histopathology, cell turnover and morphometry. No mesh-related complications were seen. The adhesion score was significantly higher in Bard Composix(®) L/P and Ethicon Proceed(®) meshes. Significant shrinkage was seen in Gore Dualmesh(®) and Parietex™ Composite meshes. Physiomesh™ exhibited the highest compliance during plunger testing, characterized by lower, more physiological reaction forces against tissue displacement than the competitor meshes. In contrast, the safety modulus was comparable in all groups. Histology showed less collagen and less foreign body reaction in the Physiomesh™ samples contributing to patient's comfort. In terms of safety, this study showed no superiority of any single mesh. The comfort modulus however differed, being lowest in the newly developed Physiomesh™. Copyright © 2011 IPEM.

  1. Provider volume and outcomes for abdominal aortic aneurysm repair, carotid endarterectomy, and lower extremity revascularization procedures.

    LENUS (Irish Health Repository)

    Killeen, Shane D

    2012-02-03

    BACKGROUND: Intuitively, vascular procedures performed by high-volume vascular subspecialists working at high-volume institutions should be associated with improved patient outcome. Although a large number of studies assess the relationship between volume and outcome, a single contemporary compilation of such studies is lacking. METHODS: A review of the English language literature was performed incorporating searches of the Medline, EMBASE, and Cochrane collaboration databases for abdominal aortic aneurysm repair (elective and emergent), carotid endarterectomy, and arterial lower limb procedures for any volume outcome relationship. Studies were included if they involved a patient cohort from 1980 onwards, were community or population based, and assessed health outcomes (mortality and morbidity) as a dependent variable and volume as an independent variable. RESULTS: We identified 74 relevant studies, and 54 were included. All showed either an inverse relationship of variable magnitude between provider volume and mortality, or no volume-outcome effect. The reduction in the risk-adjusted mortality rate (RAMR) for high-volume providers was 3% to 11% for elective abdominal aortic aneurysm (AAA) repair, 2.5 to 5% for emergent AAA repair, 0.7% to 4.7% carotid endarterectomy, and 0.3% to 0.9% for lower limb arterial bypass procedures. Subspeciality training also conferred a considerable morbidity and mortality benefit for emergent AAA repair, carotid endarterectomy, and lower limb arterial procedures. CONCLUSION: High-volume providers have significantly better outcomes for vascular procedures both in the elective and emergent setting. Subspeciality training also has a considerable impact. These data provide further evidence for the specialization of vascular services, whereby vascular procedures should generally be preformed by high-volume, speciality trained providers.

    Trichobezoar represents a mass of swallowed hair inside the stomach. Here we report a 17-year-old girl who presented in our department with symptoms of gastric ulcer. Ultrasound examination followed by upper endoscopy revealed a large trichobezoar in the stomach with simultaneous gastric perforation. Laparoscopy also revealed a penetration into the anterior abdominal wall accompanied by abscess at this level. We performed a laparoscopic gastrotomy with trichobezoar extraction and laparoscopic treatment of perforation and abdominal wall abscess. The postoperative evolution was normal and the patient was discharged on the fifth postoperative day. We show that laparoscopic approach may be safely used in the treatment of the large gastric complicated trichobezoar. Several laparoscopic approaches were described for the treatment of tricobezoar and its complications but as far as we know this is the first report of laparoscopic treatment of large tricobezoar and associate gastric perforation.

    2012-01-01

    Full Text Available In female patients presenting a tumor of the lower abdominal wall especially after cesarian section, an endometriotic tumor as well as an aggressive desmoid tumor should be considered. Symptoms in correlation with the monthly period can facilitate the presurgical differentiation between endometriosis and fibromatosis. Ultrasound reveals the typical location of both tumors and its remarkable sonographic appearance. In the clinical practice, the desmoid fibromatosis of the lower abdominal wall is a very rare disease. We present a case of a 25-year-old pregnant and discuss diagnostic and therapeutic options by a PubMed literature review. With the knowledge of the prognosis of the desmoid fibromatosis and the respective treatment options including wait and see, complete surgical resection with macroscopically free margins and adjuvant approaches is essential to avoid further interventions and progression of the locally destructive tumor.

    Full Text Available Desmoid tumor is a rare monoclonal fibroblast proliferation that is regarded as benign. The clinical management of desmoid tumors is very complex and requires a multidisciplinary approach because of the unpredictable disease course. For those cases localized in the anterior abdominal wall, symptomatic and unresponsive to medical treatment, radical resection and reconstruction with a prosthetic device are indicated. We present here a case of desmoid fibromatosis of the left anterolateral abdominal wall with a marked increase of the mass that required a large excision followed by reconstruction with biological matrix. The fact that it can be incorporated in patient tissue without a fibrotic response and that it can resist future infections, together with a very competetive price, made the new collagen matrix Egis® our first choice.

    Mucormycosis of the anterior abdominal wall is an uncommon disease and it is very rare to find this disease in immunocompetent, non-diabetic patients which usually affects patients with trauma, with contaminated wounds, patients with underlying malignancies or patients with immunocompromised state, e.g., diabetics. We herein report a case of primary cutaneous mucormycosis in an immunocompetent and non-diabetic patient. Our patient was a 48-year-old female, executive by profession. She was diagnosed to have cutaneous mucormycosis of the anterior abdominal wall, and was managed with multiple debridements of the wound and intravenous amphotericin B therapy. She was administered a total of 1500 mg of liposomal amphotericin B and when fully healed, split skin grafting was done. We would like to emphasize the importance of high index of suspicion and early start of therapy in a condition with high rate of mortality.

    Intraperitoneal bladder rupture is uncommon in very young children, but its incidence may increase with increasing use of seat and lap belts. To the best of our knowledge, there are no prior reports of laparoscopic repair of this injury in children. We describe two recent cases and discuss useful technical points that facilitate a successful laparoscopic repair. Both our patients were preschool age girls who sustained seat and lap belt injuries. Contrast computed tomography scan suggested a large amount of free peritoneal fluid and cystogram confirmed intraperitoneal bladder perforation (isolated injury). The injury was repaired using delayed absorbable sutures and intracorporeal suturing (continuous in 1, interrupted in 1) using a 3 port laparoscopic technique. Meticulous peritoneal lavage was carried out to minimise urinary peritonitis and the bladder as well as the peritoneal cavity were drained. Check cystograms (day 7) revealed no leaks. Young girls appear to be at risk of intraperitoneal bladder injuries following lap belt injuries. After exclusion of life-threatening injuries and concurrent abdominal injuries which need rapid control or preclude pneumoperitoneum, a laparoscopic repair can be safely performed. PMID:27143696

    Full Text Available Abstract Purpose The goal of this work was to determine wall shear stress (WSS patterns in the human abdominal aorta and to compare these patterns to measurements of intimal thickness (IT from autopsy samples. Methods The WSS was experimentally measured using the laser photochromic dye tracer technique in an anatomically faithful in vitro model based on CT scans of the abdominal aorta in a healthy 35-year-old subject. IT was quantified as a function of circumferential and axial position using light microscopy in ten human autopsy specimens. Results The histomorphometric analysis suggests that IT increases with age and that the distribution of intimal thickening changes with age. The lowest WSS in the flow model was found on the posterior wall inferior to the inferior mesenteric artery, and coincided with the region of most prominent IT in the autopsy samples. Local geometrical features in the flow model, such as the expansion at the inferior mesenteric artery (common in younger individuals, strongly influenced WSS patterns. The WSS was found to correlate negatively with IT (r2 = 0.3099; P = 0.0047. Conclusion Low WSS in the abdominal aorta is co-localized with IT and may be related to atherogenesis. Also, rates of IT in the abdominal aorta are possibly influenced by age-related geometrical changes.

    Prune-belly sequence (PBS) usually results from early urethral obstruction. In rare cases, PBS seems to be due to a faulty primary development of the parietal mesenchyme leading to underdevelopment of the abdominal wall musculature, and disorganization of the smooth muscles in the urinary tract. We report on two patients with segmental, unilateral wall musculature deficiency associated with homolateral agenesis of ribs. One patient also had hemivertebrae and the other one ipsilateral diaphragmatic eventration and aplasia cutis. This combination of anomalies may represent a localized deficiency in the development of somitic mesoderm mesenchyme during early embryogenesis.

    Abdominal wall closure is not possible in large congenital defects, even after extensively stretching in to enlarge its capacity. The skin coverage is usually adequate but the aponeurotic defect has to be closed temporally using synthetic patches. The use of these materials leads to increase complication such as infection, fistula formation and extrusion. In addition a second operation is required to remove the material and to perform a definitive closure. The role of fascia lata in reconstruction of abdominal wall is well established as free grafts, pedicled flaps or free flaps. Bank cadaveric fascia lata is used extensively in neurosurgical, ophtalmological, orthopaedic and urogynecological procedures. This is the first description of the use of cadaveric fascia lata for the closure of large abdominal wall defects. We present two cases of congenital diaphragmatic hernia. The first patient was a newborn who presented the impossibility to close the fascia, that was salvaged by a teflón patch. Five months later the wound opened, leaving the mesh exposed that had to be removed. A cadaveric fascia lata patch was used to cover the defect, closing the skin satisfactorily. The second case was a two days newborn. We performed the diaphragmatic closure, and the aponeurotic defect was closed using cadaveric fascia lata. Cosmetic and functional appearance are satisfactory in both cases and no complications have been seen. Fascia lata patches are revascularized in the abdominal wall and incorporates into receptor tissue. They have the following advantages with respect to synthetic materials: First, the risk of complications is lower. Second, their removal is not necessary. Finally, no intraperitoneal adhesions occur. The risks of disease transmission and rejection are minimized by the Centro Comunitario de Transfusiones donor selection and processing of the cadaveric fascia lata.

    We report a case of a rare complication of acute appendicitis with perforation through the abdominal wall. The case points out that an intraabdominal origin should be considered in patients presenting with rapidly spreading soft tissue infections of the trunk. A 58-year-old European woman presented to our hospital with a 1-week history of severe abdominal pain accompanied by rapidly spreading erythema and emphysema of the lower abdomen. On admission, the patient was in septic shock with leukocytosis and elevation of C-reactive protein. Among other diagnoses, necrotizing fasciitis was suspected. Computed tomography showed a large soft tissue infection with air-fluid levels spreading through the lower abdominal wall. During the operation, we found a perforated appendicitis breaking through the fascia and causing a rapidly progressive soft tissue infection of the abdominal wall. Appendicitis was the origin of the soft tissue infection. The abdominal wall was only secondarily involved. Even though perforated appendicitis as an etiology of a rapidly progressive soft tissue infection of the abdominal wall is very rare, it should be considered in the differential diagnosis of abdominal wall cellulitis. The distinction between rapidly spreading subcutaneous infection with abscess formation and early onset of necrotizing fasciitis is often difficult and can be confirmed only by surgical intervention.

  20. Impact of poroelasticity of intraluminal thrombus on wall stress of abdominal aortic aneurysms

    2012-08-01

    Full Text Available Abstract Background The predictions of stress fields in Abdominal Aortic Aneurysm (AAA depend on constitutive descriptions of the aneurysm wall and the Intra-luminal Thrombus (ILT. ILT is a porous diluted structure (biphasic solid–fluid material and its impact on AAA biomechanics is controversially discussed in the literature. Specifically, pressure measurements showed that the ILT cannot protect the wall from the arterial pressure, while other (numerical and experimental studies showed that at the same time it reduces the stress in the wall. Method To explore this phenomenon further a poroelastic description of the ILT was integrated in Finite Element (FE Models of the AAA. The AAA model was loaded by a pressure step and a cyclic pressure wave and their transition into wall tension was investigated. To this end ILT’s permeability was varied within a microstructurally motivated range. Results The two-phase model verified that the ILT transmits the entire mean arterial pressure to the wall while, at the same time, it significantly reduces the stress in the wall. The predicted mean stress in the AAA wall was insensitive to the permeability of the ILT and coincided with the results of AAA models using a single-phase ILT description. Conclusion At steady state, the biphasic ILT behaves like a single-phase material in an AAA model. Consequently, computational efficient FE single-phase models, as they have been exclusively used in the past, accurately predict the wall stress in AAA models.

    Three cases of blunt abdominal trauma are presented to exemplify the mechanism of trauma and the problems of diagnosis associated with any linear blow to the abdomen. The mechanisms of visceral injury are reviewed, and special attention is directed to the abdominal wall injury that can be present in these patients. This injury has special implications in directing the operative approach and repair. An unusual aortic occlusion is described which is peculiar to this type of injury.

    Full Text Available Abstract Background Development of incisional hernia after open abdominal surgery remains a major cause of post-operative morbidity. The aim of this study was to determine the current practice of surgeons in terms of access to and closure of the abdominal cavity in elective open surgery. Methods Twelve surgical departments of the INSECT-Trial group documented the following variables for 50 consecutive patients undergoing abdominal surgery: fascial closure techniques, applied suture materials, application of subcutaneous sutures, subcutaneous drains, methods for skin closure. Descriptive analysis was performed and consensus of treatment variables was categorized into four levels: Strong consensus >95%, consensus 75–95%, overall agreement 50–75%, no consensus Results 157 out of 599 patients were eligible for analysis (85 (54% midline, 54 (35% transverse incisions. After midline incisions the fascia was closed continuously in 55 patients (65%, using slowly absorbable (n = 47, 55%, braided (n = 32, 38% sutures with a strength of 1 (n = 48, 57%. In the transverse setting the fascia was closed continuously in 39 patients (72% with slowly absorbable (n = 22, 41% braided sutures (n = 27, 50% with a strength of 1 (n = 30, 56%. Conclusion In the present evaluation midline incision was the most frequently applied access in elective open abdominal surgery. None of the treatments for abdominal wall closure (except skin closure in the midline group is performed on a consensus level.

    1997-12-01

    The aim of the study was to estimate the value of CT in the diagnosis of abdominal wall hernias and at the same time to create a standard for this CT investigation. Twenty-four patients with suspected hernia of the abdominal wall were examined. All were operated on. The CT scans were assessed by two radiologists to estimate the interobserver variation. The CT diagnoses made by the two radiologists were correct in 83 % and 79 % of cases, respectively. The sensitivity was 0.83 in both CT evaluations and the specificity was 0.83 and 0.67, respectively. The predictive value of a positive CT finding was 0.94 and 0.88, while the predictive value of a negative CT finding was 0.63 and 0.57, respectively. The interobserver variation (kappa) was 0.87. The study therefore indicates that a positive CT finding of abdominal wall hernia is reliable, while a negative finding does not exclude the diagnosis. The interobserver variation of the CT diagnoses is acceptable. To achieve the highest diagnostic accuracy, it is recommended to always use the Valsalva manoeuvre, oral intake of contrast and 10/10 mm CT slices. (orig.) With 3 figs., 1 tab., 7 refs.

    We reported a case of an abdominal wall hematoma which caused by Seldinger method via the femoral artery. A 48-year-old female, suffered from direct carotid cavernous fistula, was treated by transfemoral transvenous embolization (TVE). The whole procedure was completed without difficulty except minor resistance of guide wire manipulation during left femoral artery catheterization. Four hours later, the patient became hypotensive and showed the sign of impending shock without definitive causes. Nine hours after the embolization a huge hematoma of the abdominal wall was found. It required the total 1200 m/ of blood transfusion before her blood pressure returned to normal. She recovered fully from this event and discharged uneventfully. There is a speculation that a deep circumflex iliac artery (DCIA) was injured with an angle-shaped guide wire and bled into the abdominal wall. And subsequent systemic heparinization prevented the coagulation process, resulting a large hematoma. Anatomically, an angle-shaped guide wire is easily able to migrate into DCIA. To prevent a vascular injury, it is very important to manipulate a guide wire under fluoroscopic control and to select a J-shaped guide wire instead of an angle-shaped one.

    Patients with complex ventral/incisional hernias often undergo an abdominal wall reconstruction (AWR). These operations have a high cost of care and often result in a long hospital stay and high complication rates. Using the principles of clinical quality improvement (CQI), several attempts at process improvement were implemented in one hernia program over a 3-year period. For consecutive cases of patients undergoing abdominal wall reconstruction, process improvement attempts included the use of a long-term resorbable synthetic mesh (TIGR® Resorbable Matrix, Novus Scientific, Uppsala, Sweden) in place of a biologic mesh, the use of the transversus abdominis release approach in place of an open or endoscopic component separation (external oblique release) technique, and the use of a preoperative transversus abdominis plane (TAP) block using a long-acting local anesthetic (Exparel®, Pacira Pharmaceutical, Parsippany, NJ) as a part of perioperative multi-modal pain management and an enhanced recovery program. After over 60 cases, improvement in materials costs and postoperative outcomes were documented. No mesh-related complications occurred and no mesh removal was required. In this real-world, value-based application of CQI, several attempts at process improvement led to decreased costs and improved outcomes for patients who underwent abdominal wall reconstruction for complex ventral/incisional hernias. Value-based CQI could be a tool for improved health care value globally.

    PurposeTo present our experience performing endovascular repair of abdominal aortic aneurysms in kidney transplanted patients.MethodsA retrospective review of all patients who underwent endovascular aneurysm repair (EVAR) for abdominal aortic aneurysms (AAA) performed at our institution from 2007 to 2014. We identified all patients who had previously undergone a kidney transplant. Data collected included: comorbidities, preoperative imaging modalities, indication for surgery, stent graft configurations, pre- and postoperative renal function, perioperative complications, and survival rates.ResultsA total of 267 EVARs were performed. Six (2 %) had a transplanted kidney. Mean age was 74 (range, 64–82) years; five were males. Mean time from transplantation to EVAR was 7.5 (range, 2–12) years. Five underwent preoperative planning with noncontrast modalities only. Devices used included bifurcated (n = 3), aortouniiliac (n = 2), and tube (n = 1) stent grafts. Technical success was achieved in all patients. None experienced deterioration in renal function. Median follow-up was 39 (range, 6–51) months. Four patients were alive at the time of the study. Two patients expired during the period of follow-up from unrelated causes.ConclusionsEVAR is an effective modality for the management of AAAs in the coexistence of a transplanted kidney. It can be performed with minimal morbidity and mortality without harming the transplanted kidney. Special consideration should be given to device configuration to minimize damage to the renal graft.

    The objective of this review is to assess the incidence of postoperative acute renal failure that necessitates the application of hemofiltration and to determine the factors that influence the outcome in patients undergoing surgical repair of abdominal aortic aneurysm. In addition, the review aims to assess the outcomes of postoperative early hemofiltration as compared to late intensive hemofiltration. Different forms of renal replacement therapies for use in abdominal aortic aneurysm surgery patients are discussed. Electronic literature searches were performed using Pubmed, Medline, Embase, Sumsearch, Cinahil, The Cochrane Central Register of Controlled Trials and Excerpta Medica. The search identified 419 potentially eligible studies, of which 119 were excluded based on the title and abstract. Of the remaining 300 studies, full articles were collected and re-evaluated. Forty-five articles satisfied our inclusion criteria, of which only 12 were of the IA Level of evidence. The search results indicated that the underlying disease, its severity and stage, the etiology of acute renal failure, clinical and hemodynamic status of the patient, the resources available, and different costs of therapy might all influence the choice of the renal replacement therapy strategy. However, clear guidelines on renal replacement therapy duration are still lacking. Moreover, it is not known whether in acute renal failure patients undergoing abdominal aortic aneurysm surgery, renal replacement therapy modalities can eliminate significant amounts of clinically relevant inflammatory mediators. This review gives current information available in the literature on the possible mechanisms underlying acute renal failure and recent developments in continuous renal replacement treatment modalities.

    We wanted to investigate the hemodynamic effect of fenestrated stents on the renal arteries with using a fluid structure interaction method. Two representative patients who each had abdominal aortic aneurysm that was treated with fenestrated stent grafts were selected for the study. 3D realistic aorta models for the main artery branches and aneurysm were generated based on the multislice CT scans from two patients with different aortic geometries. The simulated fenestrated stents were designed and modelled based on the 3D intraluminal appearance, and these were placed inside the renal artery with an intra-aortic protrusion of 5.0-7.0 mm to reflect the actual patients' treatment. The stent wire thickness was simulated with a diameter of 0.4 mm and hemodynamic analysis was performed at different cardiac cycles. Our results showed that the effect of the fenestrated stent wires on the renal blood flow was minimal because the flow velocity was not significantly affected when compared to that calculated at pre-stent graft implantation, and this was despite the presence of recirculation patterns at the proximal part of the renal arteries. The wall pressure was found to be significantly decreased after fenestration, yet no significant change of the wall shear stress was noticed at post-fenestration, although the wall shear stress was shown to decrease slightly at the proximal aneurysm necks. Our analysis demonstrates that the hemodynamic effect of fenestrated renal stents on the renal arteries is insignificant. Further studies are needed to investigate the effect of different lengths of stent protrusion with variable stent thicknesses on the renal blood flow, and this is valuable for understanding the long-term outcomes of fenestrated repair.

    To determine the influence of intra-abdominal pressure (IAP) on respiratory function after surgical repair of ventral hernia and to compare two different methods of IAP measurement during the perioperative period. Thirty adult patients after elective repair of ventral hernia were enrolled into this prospective study. IAP monitoring was performed via both a balloon-tipped nasogastric probe [intragastric pressure (IGP), CiMON, Pulsion Medical Systems, Munich, Germany] and a urinary catheter [intrabladder pressure (IBP), UnoMeterAbdo-Pressure Kit, UnoMedical, Denmark] on five consecutive stages: (1) after tracheal intubation (AI); (2) after ventral hernia repair; (3) at the end of surgery; (4) during spontaneous breathing trial through the endotracheal tube; and (5) at 1 h after tracheal extubation. The patients were in the complete supine position during all study stages. The IAP (measured via both techniques) increased on average by 12% during surgery compared to AI (P IGP and IBP (r = 0.65-0.81, P IGP was 8.0 (5.5-11.0) mmHg and the median IBP was 8.8 (5.8-13.1) mmHg. The overall r (2) value (n = 30) was 0.76 (P IGP or IBP demonstrated excellent concordance.

    Full Text Available INTRODUCTION: Fascial defects are a common problem in the abdominal wall and in the vagina leading to hernia or pelvic organ prolapse that requires mesh enhancement to reduce operation failure. However, the long-term outcome of synthetic mesh surgery may be unsatisfactory due to post-surgical complications. We hypothesized that mesh fabricated from alternative synthetic polymers may evoke a different tissue response, and provide more appropriate mechanical properties for hernia repair. Our aim was to compare the in vivo biocompatibility of new synthetic meshes with a commercial mesh. METHODS: We have fabricated 3 new warp-knitted synthetic meshes from different polymers with different tensile properties polyetheretherketone (PEEK, polyamide (PA and a composite, gelatin coated PA (PA+G. The rat abdominal hernia model was used to implant the meshes (25 × 35 mm, n = 24/ group. After 7, 30, 60, 90 days tissues were explanted for immunohistochemical assessment of foreign body reaction and tissue integration, using CD31, CD45, CD68, alpha-SMA antibodies. The images were analysed using an image analysis software program. Biomechanical properties were uniaxially evaluated using an Instron Tensile® Tester. RESULTS: This study showed that the new meshes induced complex differences in the type of foreign body reaction over the time course of implantation. The PA, and particularly the composite PA+G meshes, evoked a milder early inflammatory response, and macrophages were apparent throughout the time course. Our meshes led to better tissue integration and new collagen deposition, particularly with the PA+G meshes, as well as greater and sustained neovascularisation compared with the PP meshes. CONCLUSION: PA, PA+G and PEEK appear to be well tolerated and are biocompatible, evoking an overlapping and different host tissue response with time that might convey mechanical variations in the healing tissue. These new meshes comprising different polymers may

    Objective To design a technique of esophagus stomach abdominal wall drainage for the delayed intrathoracic esophageal perforation and to improve the therapeutic results.MethodsFour patients were treated by this simplified technique. There were 1 case of lower intrathoracic esophageal perforation to the left thorax, 1 high and 2 middle perforation to the right. This technique used two plastic tubes (chest tube) in a diameter about 1.2cm. One tube served as an intercostal drainage tube to drain purulent effusion, the other was inserted abdominally through stomach to the esophagus about 10cm above the esophageal perforation.ResultsThe four patients were treated successfully by the esophagus stomach abdominal wall drainage. There was no mortality or severe morbidity or complication. Hospitalizations were shortened. ConclusionThis technique is simple, safe and effective. It may provide a more promising alternative method of treatment for delayed esophageal perforation, especially in the critically ill patients. The procedure can also be extended to deal with esophagus stomach anastomotic leak.

    Full Text Available Abstract Background Aneurysms, in particular abdominal aortic aneurysms (AAA, form a significant portion of cardiovascular related deaths. There is much debate as to the most suitable tool for rupture prediction and interventional surgery of AAAs, and currently maximum diameter is used clinically as the determining factor for surgical intervention. Stress analysis techniques, such as finite element analysis (FEA to compute the wall stress in patient-specific AAAs, have been regarded by some authors to be more clinically important than the use of a "one-size-fits-all" maximum diameter criterion, since some small AAAs have been shown to have higher wall stress than larger AAAs and have been known to rupture. Methods A patient-specific AAA was selected from our AAA database and 3D reconstruction was performed. The AAA was then modelled in this study using three different approaches, namely, AAA(SIMP, AAA(MOD and AAA(COMP, with each model examined using linear and non-linear material properties. All models were analysed using the finite element method for wall stress distributions. Results Wall stress results show marked differences in peak wall stress results between the three methods. Peak wall stress was shown to reduce when more realistic parameters were utilised. It was also noted that wall stress was shown to reduce by 59% when modelled using the most accurate non-linear complex approach, compared to the same model without intraluminal thrombus. Conclusion The results here show that using more realistic parameters affect resulting wall stress. The use of simplified computational modelling methods can lead to inaccurate stress distributions. Care should be taken when examining stress results found using simplified techniques, in particular, if the wall stress results are to have clinical importance.

    Full Text Available Perforation of the inflamed diverticula is a common diverticulitis complication. It usually leads to the formation of a local abscess. In some rare cases, the inflammatory process may spread towards extra-abdominal sites like the anterior or posterior abdominal wall or the thigh and form an abscess in these sites. We present the case of a 73-year-old man with a history of pain at the lower left quadrant of the abdomen for 20 days and a visible mass in this site. Ultrasonography and computed tomography revealed this mass to be an abscess of the abdominal wall which had been formed by the spread of ruptured sigmoid diverticulitis by continuity of tissue through the lower left abdominal wall. Local drainage of the abscess was performed and the patient was discharged after alleviation of symptoms and an uneventful course. We also discuss causes of abdominal wall abscesses along with the possible pathways by which an intra-abdominal abscess could spread outside the abdominal cavity.

    Minimal evidence exists to guide surgeons on the risk of complications when performing abdominal wall reconstruction (AWR) in the presence of active infection, contamination or enterocutaneous fistula. This study aims to establish the outcomes of contaminated complex AWR. Analysis was conducted according to PRISMA guidelines. Systematic search of the MEDLINE, EMBASE and Pubmed databases was performed. Studies reporting exclusively on single-staged repair of contaminated complex AWR were included. Pooled data were analysed to establish rates of complications. Sixteen studies were included, consisting of 601 contaminated complex AWRs, of which 233 included concurrent enterocutaneous fistula repair. The average follow-up period was 26.7 months. There were 146 (24.3%) reported hernia recurrences. When stratified by repair method, suture repair alone had the lowest rate of recurrence (14.2%), followed by nonabsorbable synthetic mesh reinforcement (21.2%), biological mesh (25.8%) and absorbable synthetic mesh (53.1%). Hernia recurrence was higher when fascial closure was not achieved. Of the 233 enterocutaneous fistula repairs, fistula recurrence was seen in 24 patients (10.3%). Suture repair alone had the lowest rate of recurrence (1.6%), followed by nonbiological mesh (10.3%) and biological mesh reinforcement (12%). Forty-six per cent of patients were reported as having a wound-related complication and the mortality rate was 2.5%. It is feasible to perform simultaneous enterocutaneous fistula repair and AWR as rates of recurrent fistula are comparable with series describing enterocutaneous fistula repair alone. Hernias recurred in nearly a quarter of cases. This analysis is limited by a lack of comparative data and variability of outcome reporting.

    Biologic meshes have been used to repair abdominal wall hernia and defect for more than 10 years, and a number of clinical experience of the use of biologic mesh has been accumulated. The majority of surgeons have the opinion that biologic mesh provides an important and new tool for repair of hernia and defect of the abdominal wall, especially for the contaminated and infected fields. Most of the clinical results showed the short-term outcome of the repair of hernia and defect using biologic mesh is satisfactory, and long-term outcome need to be further investigated. A multicenter, prospective, randomized control trial should be conducted to make sure the relationship of both the types of biologic mesh and the mesh placement to the results of treatment, and the different effect of biologic mesh for repairing hernia and defect with and without contaminated and infected fields.%生物补片用于修补腹壁疝及缺损已10余年,积累了一定的临床经验.多数术者认为生物补片为外科医生修复腹壁疝和腹壁缺损、特别是有污染和感染的病人提供了重要的工具.大部分临床结果表明生物补片修补疝和腹壁缺损近期效果良好,远期效果有待进一步观察研究.对于生物补片种类与治疗效果关系,补片放置方法与治疗效果的关系,污染、感染情况下与清洁状况下使用生物补片效果差别,需要多中心、前瞻性随机对照研究.

    The primo vascular system (PVS) is being established as a circulatory system that corresponds to acupuncture meridians. There have been two critical questions in making the PVS accepted as a novel liquid flowing system. The first one was directly to show the flow of liquid in PVS and the second one was to explain why it was not observed in the conventional histological study of animal tissues. Flow in the PVS in the abdominal cavity was previously verified by injecting Alcian blue into a primo node. However, the tracing of the dye to other subsystems of the PVS has not been done. In the current work we injected fluorescent nanoparticles (FNPs) into a primo node and traced them along a primo vessel which was inside a fat tissue in the abdominal wall. Linea alba is a white middle line in the abdominal skin of a mammal and a band of fat tissue is located in parallel to the linea alba in the parietal side of the abdominal wall of a rat. In this fat band a primo vessel runs parallel to the prominent blood vessels in the fat band and is located just inside the parietal peritoneum. About the second question on the reason why the PVS was not in conventional histological study the current work provided the answer. Histological analysis with hematoxyline and eosine, Masson's trichrome, and Toluidine blue could not discriminate the primo vessel even when we knew the location of the PVS by the trace of the FNPs. This clearly explains why the PVS is hard to observe in conventional histology: it is not a matter of resolution but the contrast. The PVS has very similar structure to the connective tissues that surround the PVS. In the current work we propose a method to find the PVS: Observation of mast cell distribution with toluidine blue staining and the PN has a high density of mast cells, while the lymph node has low density.

  1. A simple, effective and clinically applicable method to compute abdominal aortic aneurysm wall stress.

    Abdominal aortic aneurysm (AAA) is a permanent and irreversible dilation of the lower region of the aorta. It is a symptomless condition that if left untreated can expand to the point of rupture. Mechanically-speaking, rupture of an artery occurs when the local wall stress exceeds the local wall strength. It is therefore desirable to be able to non-invasively estimate the AAA wall stress for a given patient, quickly and reliably. In this paper we present an entirely new approach to computing the wall tension (i.e. the stress resultant equal to the integral of the stresses tangent to the wall over the wall thickness) within an AAA that relies on trivial linear elastic finite element computations, which can be performed instantaneously in the clinical environment on the simplest computing hardware. As an input to our calculations we only use information readily available in the clinic: the shape of the aneurysm in-vivo, as seen on a computed tomography (CT) scan, and blood pressure. We demonstrate that tension fields computed with the proposed approach agree well with those obtained using very sophisticated, state-of-the-art non-linear inverse procedures. Using magnetic resonance (MR) images of the same patient, we can approximately measure the local wall thickness and calculate the local wall stress. What is truly exciting about this simple approach is that one does not need any information on material parameters; this supports the development and use of patient-specific modelling (PSM), where uncertainty in material data is recognised as a key limitation. The methods demonstrated in this paper are applicable to other areas of biomechanics where the loads and loaded geometry of the system are known. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Abdominal aortic aneurysm has a lower incidence in the female population, but a higher complication rate. It was been hypothesized that some anatomical differences of abdominal aortic aneurysm in women could be responsible for that. We proposed to analyze our data to understand the differences in the clinical and anatomical characteristics and the outcomes of patients undergoing endovascular aneurysm repair, according to gender. A retrospective analysis of patients undergoing endovascular aneurysm repair between 2001-2013 was performed. Patients were divided according gender and evaluated regarding age, atherosclerotic risk factors, aneurysm anatomic features, endograft type, anesthesic risk classification, length of stay, reinterventions and mortality. Two statistical studies were performed, first comparing women and men (Group A) and a second one comparing women and men, adjusted by age (Group B). Of the 171 patients, only 5.8% (n=10) were females. Women were older (P<0.05) and the number of women with no atherosclerotic risk factor was significantly higher. The comparison adjusted by age revealed women with statistically less smoking history, less cerebrovascular disease and ischemic heart disease. Women had a trend to more complex anatomy, with more iliac intern artery aneurysms, larger aneurysm diameter and neck angulations statistically more elevated. No other variables were statistically different between age groups, neither reintervention nor mortality rates. Our study showed a clear difference in the clinical characteristics of women. The female population was statistically older, and when compared with men adjusted by age, had less atherosclerotic risk factors and less target organ disease. Women showed a more complex anatomy but with the same outcomes.

    Full Text Available ABSTRACT Introduction: Abdominal aortic aneurysm has a lower incidence in the female population, but a higher complication rate. It was been hypothesized that some anatomical differences of abdominal aortic aneurysm in women could be responsible for that. We proposed to analyze our data to understand the differences in the clinical and anatomical characteristics and the outcomes of patients undergoing endovascular aneurysm repair, according to gender. Methods: A retrospective analysis of patients undergoing endovascular aneurysm repair between 2001-2013 was performed. Patients were divided according gender and evaluated regarding age, atherosclerotic risk factors, aneurysm anatomic features, endograft type, anesthesic risk classification, length of stay, reinterventions and mortality. Two statistical studies were performed, first comparing women and men (Group A and a second one comparing women and men, adjusted by age (Group B. Results: Of the 171 patients, only 5.8% (n=10 were females. Women were older (P<0.05 and the number of women with no atherosclerotic risk factor was significantly higher. The comparison adjusted by age revealed women with statistically less smoking history, less cerebrovascular disease and ischemic heart disease.

    Full Text Available OBJECTIVES: To systematically review studies comparing peri-operative mortality and length of hospital stay in patients with ruptured abdominal aortic aneurysms (rAAAs who underwent endovascular aneurysm repair (EVAR to patients who underwent open surgical repair (OSR. METHODS: The Medline, Cochrane, EMBASE, and Google Scholar databases were searched until Apr 30, 2013 using keywords such as abdominal aortic aneurysm, emergent, emergency, rupture, leaking, acute, endovascular, stent, graft, and endoscopic. The primary outcome was peri-operative mortality and the secondary outcome was length of hospital stay. RESULTS: A total of 18 studies (2 randomized controlled trials, 5 prospective studies, and 11 retrospective studies with a total of 135,734 rAAA patients were included. rAAA patients who underwent EVAR had significantly lower peri-operative mortality compared to those who underwent OSR (overall OR = 0.62, 95% CI = 0.58 to 0.67, P<0.001. rAAA patients with EVAR also had a significantly shorter mean length of hospital stay compared to those with OSR (difference in mean length of stay ranged from -2.00 to -19.10 days, with the overall estimate being -5.25 days (95% CI = -9.23 to -1.26, P = 0.010. There was no publication bias and sensitivity analysis showed good reliability. CONCLUSIONS: EVAR confers significant benefits in terms of peri-operative mortality and length of hospital stay. There is a need for more randomized controlled trials to compare outcomes of EVAR and OSR for rAAA.

    2016-12-01

    To determine the reliability of measurements obtained by the Good Strength dynamometer, determining isometric abdominal wall and back muscle strength in patients with ventral incisional hernia (VIH) and healthy volunteers with an intact abdominal wall. Ten patients with VIH and ten healthy volunteers with an intact abdominal wall were each examined twice with a 1 week interval. Examination included the assessment of truncal flexion and extension as measured with the Good Strength dynamometer, the completion of the International Physical Activity Questionnaire (IPAQ) and the self-assessment of truncal strength on a visual analogue scale (SATS). The test-retest reliability of truncal flexion and extension was assessed by interclass correlation coefficient (ICC), and Bland and Altman graphs. Finally, correlations between truncal strength, and IPAQ and SATS were examined. Truncal flexion and extension showed excellent test-retest reliability for both patients with VIH (ICC 0.91 and 0.99) and healthy controls (ICC 0.97 and 0.96). Bland and Altman plots showed that no systematic bias was present for neither truncal flexion nor extension when assessing reliability. For patients with VIH, no significant correlations between objective measures of truncal strength and IPAQ or SATS were found. For healthy controls, both truncal flexion (τ 0.58, p = 0.025) and extension (τ 0.58, p = 0.025) correlated significantly with SATS, while no other significant correlation between truncal strength measures and IPAQ was found. The Good Strength dynamometer provided a reliable, low-cost measure of truncal flexion and extension in patients with VIH.

    An altered collagen metabolism could play an important role in hernia development. This study compared collagen type I/III ratio and organisation between hernia and control patients, and analysed the correlation in collagen type I/III ratio between skin and abdominal wall fascia. Collagen organisation was analysed in Haematoxylin-Eosin sections of anterior rectus sheath fascia, and collagen type I/III ratio, by crosspolarisation microscopy, in Sirius-Red sections of skin and anterior rectus sheath fascia, of 19 control, 10 primary inguinal, 10 recurrent inguinal, 13 primary incisional and 8 recurrent incisional hernia patients. Compared to control patients [7.2 (IQR = 6.8-7.7) and 7.2 (IQR = 5.8-7.9)], collagen type I/III ratio was significantly lower in skin and anterior rectus sheath fascia of primary inguinal [5.2 (IQR = 3.8-6.3) and 4.2 (IQR = 3.8-4.7)], recurrent inguinal [3.2 (IQR = 3.1-3.6) and 3.3 (IQR = 3-3.7)], primary incisional [3.5 (IQR = 3-3.9) and 3.4 (IQR = 3.3-3.6)] and recurrent incisional hernia [3.2 (IQR = 3.1-3.9) and 3.2 (IQR = 2.9-3.2)] patients; also incisional and recurrent inguinal hernia had lower ratio than primary inguinal hernia patients. Furthermore, collagen type I/III ratio was significantly correlated (r = 0.81; P fascia. Finally, collagen organisation was comparable between hernia and control patients. Furthermore, in both skin and abdominal wall fascia of hernia patients, collagen type I/III ratio was lower compared to control patients, with more pronounced abnormalities in incisional and recurrent inguinal hernia patients. Importantly, collagen type I/III ratio in skin was representative for that in abdominal wall fascia.

    To analyze a single center experience of endovascular aneurysm repair (EVAR) for abdominal aortic aneurysms. Results of 122 patients who underwent EVAR were analyzed, retrospectively. Sex, age, aneurysmal morphology, hostile neck anatomy, preprocedural and postprocedural sac-diameter, technical and clinical success, postprocedural complication and need of additional procedure were analyzed. A total of 111 male and 11 female patients were included. Morphology of the aneurysms was as follows: fusiform (n = 108), saccular (n = 3) and ruptured type (n = 11). Sixty-four patients had hostile neck anatomy. The preprocedural mean sac-diameter was 52.4 mm. Postprocedural sac-diameter was decreased or stable in 110 patients (90.2%) and increased in 8 patients (6.6%). Technical success rate was 100% and clinical success rate was 86.1%. Fifty-one patients showed endoleak (41.8%) and 15 patients (12.3%) underwent secondary intervention due to type I endoleak (n = 4), type II endoleak (n = 4) and stent-graft thrombosis (n = 7). EVAR is a safe and effective therapy for abdominal aortic aneurysm, and it has high technical success and clinical success rate, and low complication rate.

    Purpose: To investigate the possibility of reducing radiation dose exposure while maintaining image quality using multidetector computed tomography angiography (MDCTA) with high-concentration contrast media in patients undergoing follow-up after endovascular aortic repair (EVAR) to treat abdominal aortic aneurysm. Materials and methods: In this prospective, single center, intra-individual study, patients underwent two consecutive MDCTA scans 6 months apart, one with a standard acquisition protocol (130 mAs/120 kV) and 120 mL of iomeprol 300, and one using a low dose protocol (100 mAs/80 kV) and 90 mL of iomeprol 400. Images acquired during the arterial phase of contrast enhancement were evaluated both qualitatively and quantitatively for image noise and intraluminal contrast enhancement. Results: Thirty adult patients were prospectively enrolled. Statistically significantly higher attenuation values were measured in the low-dose acquisition protocol compared to the standard protocol, from the suprarenal abdominal aorta to the common femoral artery (p < 0.0001; all vascular segments). Qualitatively, image quality was judged significantly (p = 0.0002) better with the standard protocol than with the low-dose protocol. However, no significant differences were found between the two protocols in terms of contrast-to-noise ratio (CNR) (13.63 {+-} 6.97 vs. 11.48 {+-} 8.13; p = 0.1058). An overall dose reduction of up to 74% was observed for the low-dose protocol compared with the standard protocol. Conclusion: In repeat follow-up examinations of patients undergoing EVAR for abdominal aortic aneurysm, a low-dose radiation exposure acquisition protocol provides substantially reduced radiation exposure while maintaining a constant CNR and good image quality.

    To evaluate the outcomes and find the prognostic factors of endovascular abdominal aortic aneurysm repair (EVAR) in patients with hostile neck anatomy of the abdominal aorta. This study was performed on 100 patients with abdominal aneurysm who were treated with EVAR between March 2006 and December 2010. We divided the patients into two groups: good neck anatomy (GNA), and hostile neck anatomy (HNA) and then compared the primary success rate and the incidence rate of complications with EVAR between the two groups. Our aim was to determine the factors related to the complications of EVAR among HNA types. There were no significant differences of primary success rate and incidence rate of complications between the two groups. Among the types of HNA, the short neck angle [odd ratio (OR), 4.23; 95% confidence interval (CI), 1.21-18.70; p = 0.023] and large neck angle (OR, 2.58; 95% CI, 0.15-11.85; p = 0.031) showed a low primary success rate. The short neck angle (OR, 2.32; 95% CI, 1.18-12.29; p = 0.002) and large neck angle (OR, 4.67; 95% CI, 0.14-19.07; p = 0.032) showed a high incidence rate of early type 1 complication. In the case of the large neck angle (OR, 3.78; 95% CI, 0.96-20.80; p = 0.047), the large neck thrombus (OR, 2.23; 95% CI, 0.24-7.12; p = 0.035) and large neck calcification (OR, 2.50; 95% CI, 0.08-18.37; p 0.043) showed a high incidence rate of complications within a year. The results suggest that patients with hostile neck anatomy can be treated with EVAR successfully, although there was a higher incidence of complications in patients with a short neck length, severe neck angulation, circumferential thrombosis, and calcified proximal neck.

    Full Text Available Degloving injuries to anterior abdominal wall are rare due to the mechanism of injury. Pedicled tensor fascia lata is known to be a versatile flap with ability to reach the lower anterior abdomen. A 34-year-old man who was involved in a road traffic accident presented with degloving injury and defect at the left inguinal region, sigmoid colon injury, and scrotal bruises. At investigation, he was found to have pelvic fracture. The management consisted of colostomy and tensor fascia lata to cover the defect at reversal. Though he developed burst abdomen on fifth postoperative day, the flap healed with no complications.

    The authors present a case of intramedullary ganglioglioma in a 6-year-old girl. Since the age of 4 months the patient had experienced a spontaneous wavy undulating movement of her anterior abdominal wall resembling a severe peristalsis. The movement was continuous even during sleep, and this symptom was named "belly dance." Magnetic resonance images revealed an intramedullary tumor with ill-defined borders, and the lesion was partially resected. The patient made a good recovery, although 4 years postsurgery her scoliosis had progressed.

    BACKGROUND: Throughout life, inguinal hernia develops in approximately every fourth man, some of whom develop multiple hernias. If patients at risk of developing multiple hernias could be identified by a serologic biomarker, treatment might be able to be tailored and improved. Evidence suggests...... that abdominal wall hernia formation is associated with altered collagen metabolism. The aim of this study was to evaluate biomarkers for type IV and V collagen turnover in patients with multiple hernias and control subjects without hernia. METHODS: Venous blood was collected from 88 men (mean age, 62 years...

    Tuberous sclerosis is a complex autosomal-dominant neurocutaneous syndrome characterized by hamartomatous malformations of fibrous and connective tissues in various organs. Although various histologic types of soft-tissue masses can occur with tuberous sclerosis, we present a unique case of fibrous hamartoma of infancy presenting as large infiltrating cutaneous and subcutaneous masses in the abdominal wall in a 4-year-old boy with tuberous sclerosis. Although the co-occurrence of tuberous sclerosis and fibrous hamartoma of infancy is very rare, it should be considered in the differential diagnosis of subcutaneous soft-tissue masses found in children with tuberous sclerosis.

    Heavy metals are able to interfere with the function of vital cellular components. Besides in trace heavy metals, which are essential at low concentration for humans, there are heavy metals with a well-known toxic and oncogenic potential. In this study, for the first time in literature, we report the unique adulthood case of an atypical primitive neuroectodermal tumor of the abdominal wall, diagnosed by histology and immunohistochemistry, with the molecular hybridization support. The neoplasia occurred in a patient chronically exposed to a transdermal delivery of heavy metal salts (aluminum and bismuth), whose intracellular bioaccumulation has been revealed by elemental microanalysis.

    Full Text Available Metastases in the thyroid gland are very rare. Even the rarer are sarcoma metastases. A 52-year-old woman was referred to our department for evaluation of a nodule in the right lobe of the thyroid gland. She had a history dermatosarcoma of the abdominal wall with known metastasis in the lung. Clinically she had neck pain and worsened swallowing. Objective assessment (ultrasound, computed tomography, and magnetic resonance indicated a voluminous right lobe nodule with mechanical syndrome, and a fine-needle aspiration biopsy revealed a very suspicious malignant finding. After surgery, the diagnosis was metastasis of dermatofibrosarcoma protuberans. Subsequent treatment was radio- and chemotherapy.

    Full Text Available Abstract Background Raoultella planticola was originally considered to be a member of environmental Klebsiella. The clinical significance of R. planticola is still not well known. Case presentation We describe the first case of necrotizing fasciitis involving the chest and abdominal wall caused by R. planticola. The identity of the organism was confirmed using 16S rRNA sequencing. The patient was successfully treated with the appropriate antibiotics combined with operative drainage and debridement. Conclusions R. planticola had been described as environmental species, but should be suspected in extensive necrotizing fasciitis after minor trauma in mild to moderate immunocompromised patients.

    The main clinical criterion for abdominal aortic aneurysm (AAA) repair operations is an AAA diameter >/=5.5 cm. When AAAs increase in size, specific changes occur in the mechanical properties of the aortic wall. Pulse-wave velocity (PWV) has been used as an indicator of vascular stiffness. A low PWV may predict AAA rupture risk and is an early predictor of cardiovascular mortality. We investigated the prognostic value of PWV before and after elective AAA repair procedures. Twenty four patients scheduled for an open AAA repair underwent a preoperative carotid-femoral aortic PWV measurement. A second aortic PWV measurement was carried out 6 months postoperatively. The mean aortic PWV increased from 7.84 +/- 1.85 preoperatively to 10.08 +/- 1.57 m/sec 6 months postoperatively (mean change: 2.25; 95% confidence interval 1.4 to 3.1 m/sec; p<0.0001). The preprocedural PWV measurement did not correlate with AAA diameter (Spearman's rank correlation coefficient rho=0.12; p=0.59). Whether the increase in aortic PWV postoperatively suggests a decreased cardiovascular risk following AAA repair remains to be established. Aortic PWV should also be investigated as an adjunct tool for assessing AAA rupture risk.

    2012-03-29

    Endovascular repair (EVAR) is accepted as effective treatment for abdominal aortic aneurysms (AAAs) and has become the standard of care in many instances. The standard bifurcated stentgraft (BFG) is often not possible in patients with unfavourable aneurysm morphology. The aorto-uni-iliac (AUI) graft configuration with femoro-femoral bypass (FFBP) is a promising alternative which may extend the scope of EVAR for AAAs. The aim of this study was to evaluate the feasibility, efficacy and durability of AUI with FFBP. Design. The results of a single institution and a single surgeon were prospectively collected from January 2002 to August 2010. All patients were followed up at 1, 3, 6 and 12 months and then annually. Results. There were 33 patients (27 males) with a mean age of 71.7 years (range 46 - 84). Open surgery posed an unacceptably high risk to all patients owing to advanced age and/or American Society of Anesthesiologists (ASA) classification 3/4. Ineligibility for BFG was due to unfavourable anatomy or a combination of factors in most cases (31 patients). Two patients had anastomotic aneurysms after previous open surgery. The technical success rate was 100%. One severe intra-operative complication occurred (perforated iliac artery). Two patients (ASA 4) died within 30 days (peri-operative mortality rate 6.1%). Seven patients (21.1%) developed postoperative wound complications. Eight patients died during follow-up of non-aneurysm-related conditions. Twenty-three patients are alive, with mean follow-up of 24.4 months and a survival rate of 69.7%. Two complications occurred during long-term follow-up, namely 1 case of graft sepsis and 1 of FFBP occlusion. Conclusion. AUI with FFBP is a safe, effective and durable alternative in high-risk patients with AAAs where standard open repair is contraindicated and BFG repair is not possible owing to unfavourable aneurysm morphology.

    To compare the wound healing of the abdominal wall of rabbits exposed to nicotine and submitted to abdominoplasty using 2-octyl cyanoacrylate or nylon thread for the surgery suture. Thirty two rabbits were used. They were divided in subgroups: A1, A2, B1 e B2. Group A received saline 0.9%; group B received nicotine, both groups for 14 days before surgery. We performed an abdominoplasty with a nylon suture into the A1 and B1 subgroups; as for A2 and B2 groups the suture was performed with cyanoacrylate. The euthanasia happened in the 14th post-operative day. After, we evaluated: swollen process, fibroblast proliferation, collagen, neovascularization, and macroscope and microscope epithelization of the scars. We observed the presence of eosinophils in all scars exposed to the cyanoacrylate, and a significant increase of neovascularization in the subgroup B2 comparing to the A2 one (p=0.037). The other variables haven't showed any statistical difference. Nicotine hasn't influenced the swollen process, the fibroblast proliferation, the presence of collagen, neither the epithelialization. The neovascularization showed cicatricial immaturity when comparing group A2 to group B2. The eosinophils in the scars repaired with glue showed that the substance has acted as an allergen.

    We report a case of right lower abdominal wall and groin abscess resulting from acute appendicitis. The patient was an 27-year-old man who had no apparent abdominal signs and was brought to the hospital due to progressive painful swelling of right lower abdomen and the groin for 10 d. Significant inflammatory changes of soft tissue involving the right lower trunk were noted without any apparent signs of peritonitis. Laboratory results revealed leukocytosis. Abdominal ultrasonography described the presence of abscess at right inguinal site also communicating with the intraabdominal region. Right inguinal exploration and laparotomy were performed and about 250 mL of pus was drained from the subcutaneous tissue and preperitoneal space. No collection of pus was found intraabdominally and subserous acute appendicitis was the cause of the abscess. The patient fully recovered at the end of the second post-operation week. This case reminds us that acute appendicitis may have an atypical clinical presentation and should be treated carefully on an emergency basis to avoid serious complications.

    The abdominal wall is an important structure differentiating subcutaneous and visceral compartments and intimately involved with maintaining abdominal structure. Segmentation of the whole abdominal wall on routinely acquired computed tomography (CT) scans remains challenging due to variations and complexities of the wall and surrounding tissues. In this study, we propose a slice-wise augmented active shape model (AASM) approach to robustly segment both the outer and inner surfaces of the abdominal wall. Multi-atlas label fusion (MALF) and level set (LS) techniques are integrated into the traditional ASM framework. The AASM approach globally optimizes the landmark updates in the presence of complicated underlying local anatomical contexts. The proposed approach was validated on 184 axial slices of 20 CT scans. The Hausdorff distance against the manual segmentation was significantly reduced using proposed approach compared to that using ASM, MALF, and LS individually. Our segmentation of the whole abdominal wall enables the subcutaneous and visceral fat measurement, with high correlation to the measurement derived from manual segmentation. This study presents the first generic algorithm that combines ASM, MALF, and LS, and demonstrates practical application for automatically capturing visceral and subcutaneous fat volumes.

    The muscles of the infrapubic abdominal wall of crocodilians play an important role in their ventilatory mechanism. Yet the anatomy and homology of these muscles is poorly understood. To gain new insights into the anatomy of the crocodilian infrapubic abdominal wall, we dissected a specimen of Crocodylus niloticus. Origin and insertion of the muscles, as well as their arrangement relative to each other was examined in great detail. The findings were compared with those of other crocodilian taxa to detect potential variability of the muscles of interest. The homology of the muscles was studied by comparing the muscles of the crocodilian infrapubic abdominal wall with those of other diapsids. In Crocodylus niloticus, the infrapubic abdominal wall consists of four muscles: Musculus truncocaudalis, M. ischiotruncus, and Mm. rectus abdominis externus and internus. The arrangement of the muscles of the infrapubic abdominal wall of Crocodylus niloticus is consistent with that found in most other crocodilian taxa. In some crocodilian taxa, an additional muscle, M. ischiopubis, is found. In the remaining diapsids, only M. rectus abdominis is present. The crocodilian M. truncocaudalis, M. ischiotruncus and, if present, M. ischiopubis appear to be derivates of M. rectus abdominis; the development of those might be related to the evolution of the unique crocodilian ventilatory mechanism.

  9. Mechanically relevant consequences of the composite laminate-like design of the abdominal wall muscles and connective tissues.

    Together, three abdominal wall muscles (external oblique, internal oblique and transversus abdominis) form a tightly bound muscular sheet that has been likened to a composite-laminate structure. Previous work has demonstrated the ability of force generated by these three muscles to be passed between one another through connective tissue linkages. Muscle fibres in each muscle are obliquely oriented with respect to its neighbouring muscles. It is proposed here is that this unique morphology of the abdominal wall muscles functions, through the application of constraining forces amongst the muscles, to increase force- and stiffness-generating capabilities. This paper presents a mathematical formulation of the stress-strain relationship for a transversely isotropic fibrous composite, and establishes a strengthening and stiffening effect when stress can be transferred between the fibrous layers. Application of empirical mechanical properties to this formulation demonstrates this effect for the abdominal wall muscles and, in greater proportion, for the anterior aponeurosis of the abdominal wall. This has implications for increasing the stiffness and passive load bearing ability of the abdominal wall muscles, and has the potential to modulate the whole muscle force-length and force-velocity relationships during contraction.

    Previous studies analyzing neuromuscular independence of the abdominal wall have involved a participant population with no specific training in separating individual muscle segments. We chose to study nine women trained in the art of middle-eastern dance, anticipating they may have unique skills in motor control. Specifically, we were searching for evidence of separation of upper rectus abdominis (URA) from lower rectus abdominis (LRA), as well as understanding what role the oblique muscles play in abdominal wall synergies. EMG analysis was done on eight trunk muscles bilaterally as the dancers participated in 30 dance, planar, and curl-up activities. The filtered data were then cross-correlated to determine the time lag between pairs of signals. Only three dance movements demonstrated consistent evidence of an ability to separate URA/LRA activation timing. The external and internal oblique muscles tend to align themselves temporally with the LRA. However, these findings were only evident in these three specific "belly-roll" conditions, all with low levels of muscle activation, and no external torque. Evidence of significantly different activation levels (% MVC) between URA/LRA was demonstrated in eight conditions, all of which required various pelvis movements with minimal thorax motion.

    Full Text Available An animal model that allows for assessment of the degree of stretching or contraction of the implant area and the in vivo degradation properties of biological meshes is required to evaluate their performance in vivo. Adult New Zealand rabbits underwent full thickness subtotal unilateral rectus abdominis muscle excision and were reconstructed with the non-biodegradable Peri-Guard®, Prolene® or biodegradable Surgisis® meshes. Following 8 weeks of recovery, the anterior abdominal wall tissue samples were collected for measurement of the implant dimensions. The Peri-Guard and Prolene meshes showed a slight and obvious shrinkage, respectively, whereas the Surgisis mesh showed stretching, resulting in hernia formation. Surgisis meshes showed in vivo biodegradation and increased collagen formation. This surgical rabbit model for abdominal wall defects is advantageous for evaluating the in vivo behaviour of surgical meshes. Implant area stretching and shrinkage were detected corresponding to mesh properties, and histological analysis and stereological methods supported these findings.

    Full Text Available The objective of this study was to determine the inter- and intra-examiner reliability of pain pressure threshold algometry at various points of the abdominal wall of healthy women. Twenty-one healthy women in menacme with a mean age of 28 ± 5.4 years (range: 19-39 years were included. All volunteers had regular menstrual cycles (27-33 days and were right-handed and, to the best of our knowledge, none were taking medications at the time of testing. Women with a diagnosis of depression, anxiety or other mood disturbances were excluded. Women with previous abdominal surgery, any pain condition or any evidence of inflammation, hypertension, smoking, alcoholism, or inflammatory disease were also excluded. Pain perception thresholds were assessed with a pressure algometer with digital traction and compression and a measuring capacity for 5 kg. All points were localized by palpation and marked with a felt-tipped pen and each individual was evaluated over a period of 2 days in two consecutive sessions, each session consisting of a set of 14 point measurements repeated twice by two examiners in random sequence. There was no statistically significant difference in the mean pain threshold obtained by the two examiners on 2 diferent days (examiner A: P = 1.00; examiner B: P = 0.75; Wilcoxon matched pairs test. There was excellent/good agreement between examiners for all days and all points. Our results have established baseline values to which future researchers will be able to refer. They show that pressure algometry is a reliable measure for pain perception in the abdominal wall of healthy women.

    Desmoid tumours are one of the rarest tumours worldwide, with an estimated yearly incidence of 2-4 new cases per million people. They are soft tissue monoclonal neoplasms that originate from mesenchymal stem cells. It seems that the hormonal and immunological changes occurring during pregnancy may play a role in the severity and course of the disease. The case is presented on 28-year-old female in her fifth week of gestation, in whom an abdominal wall tumour was found attached to left adnexa and uterus while performing a prenatal ultrasound. The patient was followed up under clinical and ultrasonographic surveillance. When she presented with abnormal uterine activity at 38.2 weeks of gestation, she was admitted and obstetrics decided to perform a caesarean section. Tumour biopsy was taken during the procedure. Histopathology reported a desmoid fibromatosis. A contrast enhanced abdominal computed tomography scan was performed, showing a tumour of 26×20.5×18cm, with well-defined borders in contact with the uterus, left adnexa, bladder and abdominal wall, with no evidence of infiltration to adjacent structures. A laparotomy, with tumour resection, hysterectomy and left salpingo-oophorectomy, components separation techniques, polypropylene mesh insertion, and drainage was performed. The final histopathology report was desmoid fibromatosis. There is no evidence of recurrence after 6 months follow-up. Desmoid tumours are locally aggressive and surgical resection with clear margins is the basis for the treatment of this disease, using radiotherapy, chemotherapy and hormone therapy as an adjunct in the treatment.

The disease has no relation with antecedents of previous surgery or trauma and is asociated with a dyasthasis of the rectus abdomini muscles which has conditionated a intestinal evisceration.This evisceration is accommodated in the abdominal apron and is associated with a great accumulation of fluid (liquid in the interstitium, which seems a linphedema. Taking account the combination of liquid and soft tissues the resection is larger than 60 Kg. and this has forced us to develop new strategies for the menagement of the patient and techniques for the reconstruction of the abdominal wall defect.

OBJETIVO: Avaliar os resultados da cirurgia do AAA em pacientes com idade BACKGROUND: Abdominal aortic aneurysms (AAA are rare in young patients. OBJECTIVE: To evaluate outcomes after AAA repair in patients aged < 50 years. METHODS: Between June 1979 and January 2008, 946 patients underwent elective repair for an infrarenal AAA performed by the first author. Of these, 13 patients (1.4% were < 50 years old at surgery. Demographic characteristics and surgical data were analyzed, as well as early and late outcomes after surgical intervention. RESULTS: Mean age was 46±3.4 years (ranging from 43 to 50 years. Most patients were men (76.9%, hypertensive (76.9% and smokers (61.5%. Perioperative morbidity and mortality rates were low (15.4% and 0%, respectively; one patient had respiratory infection and another patient had unstable angina. Median follow-up was 85.5 months, and two patients died due to ischemic cardiopathy and cerebrovascular accident during the follow-up period. CONCLUSION: AAA repair in young patients is a safe procedure, with good long-term results. In our study, there were no perioperative deaths, and a good long-term survival was observed.

    Full Text Available Among the various complications associated with ventriculoperitoneal shunt (VPS surgery, migration of the peritoneal catheter is one of the rarest complications. We report two cases of spontaneous extrusion of the peritoneal portion of the VPS through the intact abdominal wall at an area unrelated to the surgical incision. Both were conscious and had no neurological deficits. There were no signs of infection. The peritoneal end of the shunt was removed through the abdomen. Shunt revision was performed. The patients were discharged 8 days after the revision without any complications. At 6-month follow-up, both of them are doing well. Possible mechanisms of abdominal wall perforation are discussed. Pulling the extruded peritoneal end through abdominal wall decreases the possibility of infection and is probably the best way of management.

    MARIA VITÓRIA FRANÇA DO AMARAL

    Full Text Available ABSTRACT We describe the preliminary national experience and the early results of the use of robotic surgery to perform the posterior separation of abdominal wall components by the Transversus Abdominis Release (TAR technique for the correction of complex defects of the abdominal wall. We performed the procedures between 04/2/2015 and 06/15/2015 and the follow-up time was up to six months, with a minimum of two months. The mean surgical time was five hours and 40 minutes. Two patients required laparoscopic re-intervention, since one developed hernia by peritoneal migration of the mesh and one had mesh extrusion. The procedure proved to be technically feasible, with a still long surgical time. Considering the potential advantages of robotic surgery and those related to TAR and the results obtained when these two techniques are associated, we conclude that they seem to be a good option for the correction of complex abdominal wall defects.

    Full Text Available Isolated abdominal wall actinomycosis in the presence of an intrauterine contraceptive device (IUCD is extremely rare and only six such cases have been reported in the literature. We report a case where clinical and radiological examinations revealed a pseudotumor within the anterior abdominal wall. After being lost to follow-up, the patient presented two years later with the enlargement of the mass. The mass including the affected anterior abdominal wall was completely excised. The diagnosis of actinomycosis was established postoperatively by histopathological examination. Further questioning concerning her gynecological history revealed long-term use of the same IUCD. Surgical excision of the actinomycotic pseudotumour and removal of the IUCD followed by antibiotic therapy resulted in the full recovery of the patient.

    The use of the endovascular prostheses in abdominal aortic aneurysm has proven to be an effective technique to reduce the pressure and rupture risk of aneurysm. Nevertheless, in a long-term perspective, complications such as leaks inside the aneurysm sac (endoleaks) could appear causing a pressure elevation and increasing the danger of rupture consequently. At present, computed tomographic angiography (CTA) is the most common examination for medical surveillance. However, endoleak complications cannot always be detected by visual inspection on CTA scans. The investigation on new techniques to detect endoleaks and analyse their effects on treatment evolution is of great importance for endovascular aneurysm repair (EVAR) technique. The purpose of this work was to evaluate the capability of texture features obtained from the aneurysmatic thrombus CT images to discriminate different types of evolutions caused by endoleaks. The regions of interest (ROIs) from patients with different post-EVAR evolution were extracted by experienced radiologists. Three techniques were applied to each ROI to obtain texture parameters, namely the grey level co-occurrence matrix (GLCM), the grey level run length matrix (GLRLM) and the grey level difference method (GLDM). The results showed that GLCM, GLRLM and GLDM features presented a good discrimination ability to differentiate between favourable or unfavourable evolutions. GLCM was the most efficient in terms of classification accuracy (93.41% ± 0.024) followed by GLRLM (90.17% ± 0.077) and finally by GLDM (81.98% ± 0.045). According to the results, we can consider texture analysis as complementary information to classified abdominal aneurysm evolution after EVAR.

    [Purpose] Continuous electrical stimulation of abdominal wall muscles is known to induce mild muscle fatigue. However, it is not clear whether this is also true for functional electrical stimulation delivered only during the expiratory phase of breathing. This study aimed to examine whether or not intermittent electrical stimulation delivered to abdominal wall muscles induces muscle fatigue. [Subjects and Methods] The subjects were nine healthy adults. Abdominal electrical stimulation was applied for 1.5 seconds from the start of expiration and then turned off during inspiration. The electrodes were attached to both sides of the abdomen at the lower margin of the 12th rib. Abdominal electrical stimulation was delivered for 15 minutes with the subject in a seated position. Expiratory flow was measured during stimulus. Trunk flexor torque and electromyography activity were measured to evaluate abdominal muscle fatigue. [Results] The mean stimulation on/off ratio was 1:2.3. The declining rate of abdominal muscle torque was 61.1 ± 19.1% before stimulus and 56.5 ± 20.9% after stimulus, not significantly different. The declining rate of mean power frequency was 47.8 ± 11.7% before stimulus and 47.9 ± 10.2% after stimulus, not significantly different. [Conclusion] It was found that intermittent electrical stimulation to abdominal muscles synchronized with the expiratory would not induce muscle fatigue.

    Endovascular aneurysm repair of the infrarenal or thoracic aorta has been shown to be a less invasive alternative to open surgery. A combined aneurysm of the thoracic and abdominal aorta is complex and challenging; the involvement of renal and/or visceral branches requires new treatment methods. A hybrid approach is currently an accepted alternative to conventional surgery. Renal and/or visceral revascularisation enables subsequent stent-graft placement into the visceral portion of the aorta. Knowledge of the surgical procedure and a precise assessment of the vascular morphology are crucial for pre-procedural planning and for detection of post-procedural complications. Multi-detector computed tomography angiography (MDCTA) combined with two- and three-dimensional (2D and 3D) rendering is useful for pre-interventional planning and for the detection of post-procedural complications. Three-dimensional rendering allows proper anatomical analyses, influencing interventional strategies and resulting in a better outcome. With the knowledge of procedure-specific MDCTA findings in various vascular conditions, the radiologist and surgeon are able to perform an efficient pre-interventional planning and follow-up examination. Based on our experience with this novel technique of combined open and endovascular aortic aneurysm treatment, this pictorial review illustrates procedure-specific imaging findings, including common and rare complications, with respect to 2D and 3D post-processing techniques.

    PurposeThe purpose of this study was to demonstrate a sac angiography technique and evaluate the feasibility of N-butyl cyanoacrylate (NBCA) embolization of the ruptured abdominal aortic aneurysm (AAA) sac in emergency endovascular aneurysm repair (EVAR) in hemodynamically unstable patients.MethodsA retrospective case series of three patients in whom sac angiography was performed during emergency EVAR for ruptured AAA was reviewed. After stent graft deployment, angiography within the sac of aneurysm (sac angiography) was performed by manually injecting 10 ml of contrast material through a catheter to identify the presence and site of active bleeding. In two patients, sac angiography revealed active extravasation of the contrast material, and NBCA embolization with a coaxial catheter system was performed to achieve prompt sealing.ResultsSac angiography was successful in all three patients. In the two patients who underwent NBCA embolization for aneurysm sac bleeding, follow-up computed tomography (CT) images demonstrated the accumulation of NBCA consistent with the bleeding site in preprocedural CT images.ConclusionsEVAR is associated with a potential risk of ongoing bleeding from type II or IV endoleaks into the disrupted aneurysm sac in patients with severe coagulopathy. Therefore, sac angiography and NBCA embolization during emergency EVAR may represent a possible technical improvement in the treatment of ruptured AAA in hemodynamically unstable patients.

    Half of the female population over age 50 years will experience pelvic organ prolapse. We suggest a new approach based on tissue engineering principles to functionally reconstruct the anatomical structures of the pelvic floor. The aim of this study is to investigate the mechanical performance...... and effect on collagen and elastin production of a degradable mesh releasing basic fibroblast growth factor (bFGF). Implantation of biodegradable mesh with or without bFGF in their core has been conducted in 40 rats in an abdominal wall defect model. Samples were explanted after 4, 8, and 24 weeks...... after 4 weeks with bFGF but signs of elastin fibers were seen at 24 weeks. The investigation showed that a biodegradable mesh promotes tissue formation with a promising strength. The mesh with bFGF did not represent any advantage on either long or short term in comparison to the mesh without b...

    AIM: To determine the complications and incidence of the first and second access-related vascular injuries induced by videolaparoscopic cholecistectomy.METHODS: We retrospectively reviewed vascular injuries in 200 consecutive patients who underwent videolaparoscopic cholecistectomy from 2003 to 2005.One hundred and one patients with placement of radial expanding trocars were assigned into group A and 99patients with placement of pyramidal tipped trocars into group B. All the patients were submitted to open access according to Hasson for the first trocar.RESULTS: Bleeding did not occur at the intraoperative cannula-site in group A. However, it occurred at the intraoperative cannula-site of 7 patients (7.1%) in group B, with a statistically significant difference (P < 0.01).No mortality was registered. More vascular lesions were found in group B.CONCLLSION: The advantage of Hasson technique is that peritoneal cavity access is gained under direct vision, preventing most severe injuries. The open technique with radial expanding trocars is recommended for secure access to the abdominal cavity in videolaparoscopy. Great care should be taken to avoid major complications and understanding the abdominal wall anatomy is important for reducing bleeding during or after s placement of trocars.

    Full Text Available Pancreatitis indicates inflammation of the pancreas. Clinically acute pancreatitis typically presents as upper abdominal pain mostly in epigastric region, nausea, vomiting and elevated levels of amylase and lipase. Depending upon severity of acute pancreatitis patient may presents with minimal symptoms to more severe signs of acute abdomen like generalized guarding and rigidity. Inspite of absence of disease-specific signs and symptoms for acute pancreatitis, diagnosis is usually not difficult using a combination of clinical, laboratory and radiological findings. Sometimes pancreatitis may presents atypically, which may be misleading in the management especially when typical presentation of pancreatitis as described above is absent. We have described a case of pancreatitis where patient presented with anterior abdominal wall abscess with epididymo-orchitis because of tracking of pancreatic fluid into the retroperitoneum till scrotum. Patients presentation may be different depending upon complication occurred during the course of pancreatitis. After reviewing the literature we found very few cases in which you may not get a clue to diagnose pancreatitis because of atypical presentation. In the described case, patient managed conservatively with percutaneous drainage of the abscess by pigtail catheter placement and scrotal support for epididymoorchitis. This avoided unnecessary exploration in above patient.

  14. Deletion of mesenchymal glucocorticoid receptor attenuates embryonic lung development and abdominal wall closure.

    Directory of Open Access Journals (Sweden)

    Aiqing Li

    Full Text Available As a member of the nuclear hormone receptor superfamily of ligand-activated transcription factors, the glucocorticoid receptor (GR is essential for normal embryonic development. To date, the role of mesenchymal glucocorticoid signaling during development has not been fully elucidated. In the present study, we investigated the role of the GR during embryogenesis specifically in mesenchymal tissues. To this aim, we crossed GRflox mice with Dermo1-Cre mice to generate GR(Dermo1 mice, where the GR gene was deleted within mesenchymal cells. Compared to their wild type littermates, GR(Dermo1 mice displayed severe pulmonary atelectasis, defects in abdominal wall formation resulting in intestinal herniation, abnormal extracellular matrix synthesis in connective tissues and high postnatal lethality. Lungs of GR(Dermo1 mice failed to progress from the canalicular to saccular stage, as evidenced by the presence of immature air sacs, thickened interstitial mesenchyme and an underdeveloped vascular network between E17.5 and E18.5. Furthermore, myofibroblasts and vascular smooth muscle cells, although present in normal numbers in GR(Dermo1 animals, were characterized by significantly reduced elastin synthesis, whilst epithelial lining cells of the immature saccules were poorly differentiated. A marked reduction in normal elastin and collagen deposits were also observed in connective tissues adjacent to the umbilical hernia. This study demonstrates that eliminating the GR in cells of the mesenchymal lineage results in marked effects on interstitial fibroblast function, including a significant decrease in elastin synthesis. This results in lung atelectasis and postnatal lethality, as well as additional and hitherto unrecognized developmental defects in abdominal wall formation. In addition, altered glucocorticoid signaling in the mesenchyme attenuates normal lung epithelial differentiation.

    Objective: To study MRI findings of abdominal wall edema (AWE) in acute pancreatitis as well as correlations between AWE and the severity of acute pancreatitis according to the MR severity index (MRSI) and the Acute Physiology And Chronic Healthy Evaluation III (APACHE III) scoring system. Materials and methods: A total of 160 patients with AP admitted to our institution between December 2009 and March 2011 were included in this study. MRI was performed within 48 h after admission. MRI findings of acute pancreatitis were noted, including AWE on the MRI. The abdominal wall area was divided into quarters, and each area involved was recorded as 1 point to score the severity of AWE. The severity of acute pancreatitis was studied using both the MRSI and the APACHE III scoring system. Spearman correlation of AWE with the MRSI and the APACHE III scoring system was analyzed. Results: In 160 patients with acute pancreatitis, 53.8% had AWE on MRI. The average AWE score was 1.2 {+-} 1.4 points. The prevalence of AWE was 30.5%, 64.5% and 100% in mild, moderate and severe AP, respectively, according to MRSI. AWE on MRI was correlated with MRSI scores (r = 0.441, p = 0.000). According to APACHE III scores, the averages were 2.0 {+-} 1.1 and 2.6 {+-} 1.1 points in mild AP and severe AP, respectively (P = 0.016). AWE was slightly correlated with the APACHE III scores (r = 0.222, p = 0.005). Conclusion: AWE on MRI in acute pancreatitis is common, which may be a supplementary indicator in determining the severity of AP.

    Although abdominal aortic aneurysms (AAAs) occur mostly inferior to the renal artery, the mechanism of the development of AAA in relation to its specific location is not yet clearly understood. The objective of this study was to evaluate the hypothesis that even healthy volunteers may manifest specific flow characteristics of blood flow and alter wall shear or oscillatory shear stress in the areas where AAAs commonly develop. Eight healthy male volunteers were enrolled in this prospective study, aged from 24 to 27. Phase-contrast magnetic resonance imaging (MRI) was performed with electrocardiographic triggering. Flow-sensitive four-dimensional MR imaging of the abdominal aorta, with three-directional velocity encoding, including simple morphological image acquisition, was performed. Information on specific locations on the aortic wall was applied to the flow encodes to calculate wall shear stress (WSS) and oscillatory shear index (OSI). While time-framed WSS showed the highest peak of 1.14 ± 0.25 Pa in the juxtaposition of the renal artery, the WSS plateaued to 0.61 Pa at the anterior wall of the abdominal aorta. The OSI peaked distal to the renal arteries at the posterior wall of the abdominal aorta of 0.249 ± 0.148, and was constantly elevated in the whole abdominal aorta at more than 0.14. All subjects were found to have elevated OSI in regions where AAAs commonly occur. These findings indicate that areas of constant peaked oscillatory shear stress in the infra-renal aorta may be one of the factors that lead to morphological changes over time, even in healthy individuals.

    Malignant peripheral nerve sheath tumors (MPNST) are highly malignant soft tissue sarcomas. It is very rare for MPNST to arise in the abdominal wall. We report a case of abdominal wall MPNST that was difficult to distinguish from a urachal disease. A 72-year-old woman found a mass of the umbilicus in October 2011. She visited a digestive surgery department in November because it gradually enlarged. Diagnostic imaging suggested a urachal tumor. She was then referred to our clinic. Contrast enhanced CT showed that the 5-cm cystic tumor extended from the umbilicus to abdominal wall. The tumor showed low uptake value in PET-CT. We diagnosed her with a urachal cyst, but could not deny urachal carcinoma. Therefore, we performed surgical resection in January 2012. The pathological diagnosis was MPNST. She has not experienced recurrence for 9 months. MPNST mostly occur in the retroperitoneum close to the spine, extremities, head, and neck. It is very rare for them to occur in the abdominal wall. This is the sixth case including overseas reports. In addition, this is the first case in which it was difficult to distinguish from a urachal disease.

    Full Text Available Abstract Introduction Endovascular abdominal aortic aneurysm repair is a life-saving intervention. Nevertheless, complications have a major impact. We review the evidence from case reports for risk factors of complications after endovascular abdominal aortic aneurysm repair. Case presentation We selected case reports from PubMed reporting original data on adverse events after endovascular abdominal aortic aneurysm repair. Extracted risk factors were: age, sex, aneurysm diameter, comorbidities, re-interventions, at least one follow-up visit being missed or refusal of a re-intervention by the patient. Extracted outcomes were: death, rupture and (non-device-related complications. In total 113 relevant articles were selected. These reported on 173 patients. A fatal outcome was reported in 15% (N = 26 of which 50% came after an aneurysm rupture (N = 13. Non-fatal aneurysm rupture occurred in 15% (N = 25. Endoleaks were reported in 52% of the patients (N = 90. In half of the patients with a rupture no prior endoleak was discovered during follow-up. In 83% of the patients one or more re-interventions were performed (N = 143. Mortality was higher among women (risk ratio 2.9; 95% confidence interval 1.4 to 6.0, while the presence of comorbidities was strongly associated with both ruptures (risk ratio 1.6; 95% confidence interval 0.9 to 2.9 and mortality (risk ratio 2.1; 95% confidence interval 1.0 to 4.7. Missing one or more follow-up visits (≥1 or refusal of a re-intervention by the patient was strongly related to both ruptures (risk ratio 4.7; 95% confidence interval 3.1 to 7.0 and mortality (risk ratio 3.8; 95% confidence interval 1.7 to 8.3. Conclusion Female gender, the presence of comorbidities and at least one follow-up visit being missed or refusal of a re-intervention by the patient appear to increase the risk for mortality after endovascular abdominal aortic aneurysm repair. Larger aneurysm diameter, higher age and multimorbidity at the time

Under certain situations, for example, the vacuum vessel should be vented to repair in-vessel components such as diagnostic shutter, exchange of window for diagnostic equipment, and PFC damaged by high energy plasma. For the quick restart of the campaign, a recovery process was established to make the vacuum condition acceptable for the plasma experiment. In this paper, we present the recovery process of wall condition in KSTAR after temporal machine-vent for repair. It is found that an acceptable vacuum condition has been achieved only by plasma based wall conditioning techniques such as baking, GDC, and boronization. This study was that the proper recovering method of the vacuum condition should be developed according to the severity of the accident.

    AIM: To investigate distal small bowel motility and lipid absorption in patients following elective abdominal aortic aneurysm (AAA) repair surgery.METHODS: Nine patients (aged 35-78 years; body mass index (BMI) range: 23-36 kg/m2) post-surgery for AAA repair, and seven healthy control subjects (20-50 years;BMI range: 21-29 kg/m2) were studied. Continuous distal small bowel manometry was performed for up to 72 h, during periods of fasting and enteral feeding (Nutrison(R)). Recordings were analyzed for the frequency,origin, length of migration, and direction of small intestinal burst activity. Lipid absorption was assessed on the first day and the third day post surgery in a subset of patients using the 13C-triolein-breath test, and compared with healthy controls. Subjects received a 20-min intraduodenal infusion of 50 mL liquid feed mixed with 200 μL 13C-triolein. End-expiratory breath samples were collected for 6 h and analyzed for 13CO2 concentration.RESULTS: The frequency of burst activity in the proximal and distal small intestine was higher in patients than in healthy subjects, under both fasting and fed conditions (P<0.005). In patients there was a higher proportion of abnormally propagated bursts (71% abnormal), which began to normalize by d 3 (25% abnormal) post-surgery.Lipid absorption data was available for seven patients on d 1 and four patients on d 3 post surgery. In patients,absorption on d 1 post-surgery was half that of healthy control subjects (AUC 13CO2 1323 ± 244 vs 2 646 ±365;P< 0.05, respectively), and was reduced to the one-fifth that of healthy controls by d 3 (AUC 13CO2 470 ± 832 vs 2646 ± 365; P< 0.05, respectively).CONCLUSION: Both proximal and distal small intestinal motor activity are transiently disrupted in critically ill patients immediately after major surgery,with abnormal motility patterns extending as far as the ileum. These motor disturbances may contribute to impaired absorption of enteral nutrition, especially when

    Previous reports suggest that percutaneous access for endovascular abdominal aortic aneurysm repair (P-EVAR) is as safe as open access (O-EVAR) in patients with favorable femoral anatomy. Severe femoral artery calcification and obesity have been considered relative contraindications to P-EVAR, but these criteria have not been evaluated. The purpose of this study was to assess the postoperative anatomic changes associated with P-EVAR versus O-EVAR using three-dimensional (3-D) computed tomographic (CT) reconstruction and to evaluate the overall results of the two procedures in a group of patients with suboptimal femoral anatomy. During a recent 26-month period, 173 patients underwent EVAR at our institutions, including 35 P-EVARs. Of these, 22 (63%) had complete pre- and postoperative CT imaging of the femoral arteries. These subjects were compared to 22 matched controls who underwent O-EVAR during the same period. Automated 3-D reconstructions were used to measure the following anatomic femoral artery parameters before and after EVAR: arterial depth, calcification score, minimum diameter and area, and maximum diameter and area. Of the 88 study arteries, 50 underwent open access and 38 percutaneous access (Proglide, n=11; Prostar XL, n=27). Both groups were similar regarding sheath size, number of components, operative time, blood loss, and length of stay. Significantly more O-EVAR subjects suffered groin complications (p=0.02), including five hematomas, two wound infections, two femoral thromboses, and one vessel which required patch repair. In the P-EVAR group there was only one hematoma, which was managed conservatively. There was no difference between the P-EVAR and O-EVAR groups with respect to femoral artery calcification (Agatston scores 667+/-719 vs. 945+/-1,248, p=0.37). Obesity (body mass index >30) was documented in six (27%) of both the P-EVAR and O-EVAR groups (p=nonsignificant). Pre- and postoperative CT-derived anatomic data showed a significant

    Endovascular abdominal aortic aneurysms repair (EVAR) involves the minimally invasive implantation of a stent-graft within the aorta to exclude the aneurysm from the circulation thus preventing its rupture. The feasibility of such operation is highly dependent on the aorta morphology and in general the presence of one/both renal arteries emerging from the aneurysm is the absolute limit for the implantation of a standard stent-graft. Consequently, classical intervention methods involve the implantation of a custom-made graft with fenestrations, leading to extremely complicated surgeries with high risks for the patient and high costs. Recent techniques introduced the use of standard grafts (i.e. without fenestrations) in association with mechanical in-situ fenestration, but this procedure is limited principally by the brittleness and low stability of the environment, in addition to the difficulty of controlling the guidance of the endovascular tools due to the temporarily block of the blood flow. In this work we propose an innovative EVAR strategy, which involves in-situ fenestration with a fiber guided laser tool, controlled via an electromagnetic navigation system. The fiber is sensorized to be tracked by means of the driving system and, using a 3D model of the patient anatomy, the surgeon can drive the fiber to the aneurysm, where the stent has been previously released, to realize the proper fenestration(s). The design and construction of the catheter laser tool will be presented, togheter with preliminary fenestration tests on graft-materials, including the effects due to the presence of blood and tissues.

    Full Text Available Background/Aim. The main complication of the atherosclerotic abdominal aortic aneurism (AAA is her rupture that begins with lesion in intima and rupture. The purpose of this work was to determine immunocytochemical and morphofunctional characteristics of the cells in aortic wall in ruptured atherosclerotic abdominal aortic aneurysm. Method. During the course of this study, 20 samples of atherosclerotic AAA were analyzed, all of them obtained during authopsy. The samples were fixed in 4% formalin and embedded in paraffin. Sections of 5 μm thickness were stained histochemically (of Heidenhain azan stain and Periodic acid Schiff - PAS stain and immunocytochemically using a DAKO LSAB+/HRP technique to identify α-smooth muscle actin (α-SMA, vimentin, myosin heavy chains (MHC, desmin, S-100 protein, CD45 and CD68 (DAKO specification. Results. The results of our study showed that ruptured atherosclerotic AAA is characterized by a complete absence of endothelial cells, the disruption of basal membrane and internal elastic lamina, as well as a presence of the remains of hypocellular complicated atherosclerotic lesion in intima. On the plaque margins, as well as in the media, smooth muscle cells (SMCs are present, which express a α-SMA and vimentin (but without MHC or desmin expression, as well as leukocyte infiltration, and a large number of foam cells. Some of the foam cells show a CD68-immunoreactivity, while the others show vimentin- and S-100 protein-immunoreactivity. Media is thinned out with a disorganized elastic lamellas, while adventitia is characterized by inflammatory inflitrate (infection. Conclusion. Rupture of aneurysm occurs from the primary intimal disruption, which spreads into thinned out media and adventitia. Rupture is caused by unstable atherom, hypocellularity, loss of contractile characteristics of smooth muscle cells in intima and media, neovascularization of the media, as well as by the activity of the macrophages in the

    An abdominal aortic aneurysm (AAA) is an area of a localized widening of the abdominal aorta, with a frequent presence of thrombus. A ruptured aneurysm can cause death due to severe internal bleeding. AAA thrombus segmentation and quantitative analysis are of paramount importance for diagnosis, risk assessment, and determination of treatment options. Until now, only a small number of methods for thrombus segmentation and analysis have been presented in the literature, either requiring substantial user interaction or exhibiting insufficient performance. We report a novel method offering minimal user interaction and high accuracy. Our thrombus segmentation method is composed of an initial automated luminal surface segmentation, followed by a cost function-based optimal segmentation of the inner and outer surfaces of the aortic wall. The approach utilizes the power and flexibility of the optimal triangle mesh-based 3-D graph search method, in which cost functions for thrombus inner and outer surfaces are based on gradient magnitudes. Sometimes local failures caused by image ambiguity occur, in which case several control points are used to guide the computer segmentation without the need to trace borders manually. Our method was tested in 9 MDCT image datasets (951 image slices). With the exception of a case in which the thrombus was highly eccentric, visually acceptable aortic lumen and thrombus segmentation results were achieved. No user interaction was used in 3 out of 8 datasets, and 7.80 +/- 2.71 mouse clicks per case / 0.083 +/- 0.035 mouse clicks per image slice were required in the remaining 5 datasets.

    Full Text Available Gardner syndrome (GS is a rare entity characterized by a triad of familial colonic polyposis, multiple osteomas and soft tissue tumors, including desmoid tumor (DT. This is a case report of a 30 year-old patient with GS who developed giant DT in the abdominal wall after undergoing several laparotomies. The patient has taken a long time to search for medical care, and at first he saw another team that refused to operate him by judging the lesion unresectable. The surgery in our department was performed in three steps. Initially, we resected the lesion with macroscopic margins, and as there were small bowel adhesions in the tumor, we performed enterectomy and closed using the "Bogotá" technique, with skin closure on the bag. On the fourth postoperative day (POD, we reoperated the abdomen without identifying any signs of fistula. On the seventh POD there was another surgical intervention, this time to insert a double-sided mesh. The patient recovered well, and had no debilitating motor deficit, despite the extensive resection of the abdominal muscles. Curative treatment of DT is based on surgical resection and only sequential surveillance allows us an early diagnosis, when the lesion is still resectable.Tumor desmoide gigante de parede abdominal em paciente portador da Síndrome de Gardner.

    Vaginal cuff dehiscence is a rare but serious complication that can develop after hysterectomy. Emergent surgical intervention is required for vaginal cuff dehiscence due to the potential subsequent vaginal evisceration, which may lead to necrosis of the small bowel. A 62-year-old nulliparous woman with a 30-year history of smoking, diabetes mellitus, and rheumatoid arthritis (treated with oral steroids) presented with a vaginal cuff dehiscence. Thirty-eight days before the admission, she had undergone a radical operation including total abdominal hysterectomy for uterine corpus cancer at another hospital. We performed emergent laparoscopic surgery to reduce the prolapsed small bowel into the abdominal cavity and repaired the vaginal cuff with a two-layer continuous closure using absorbable barbed sutures. The patient experienced no postoperative complications, and no recurrence of the vaginal cuff dehiscence occurred. Vaginal cuff dehiscence and evisceration can be surgically managed using an abdominal, vaginal, or laparoscopic approach, and the choice of method should be based on patient characteristics and the surgeon's skills. Laparoscopic vaginal cuff repair with a two-layer continuous closure using absorbable barbed sutures is a minimally invasive technique that is safe and effective for medically stable patients with no small bowel injury or vascular compromise and no pelvic abscess.

    Full Text Available Tumores desmóides são neoplasias do tecido conjuntivo, caracterizadas por apresentarem crescimento exclusivamente loco-regional, recorrência freqüente e mínimo potencial metastático. Acometem principalmente portadores de polipose adenomatosa familial dos cólons, sendo sua ocorrência isolada extremamente rara. São mais freqüentes nas mulheres em idade reprodutiva e durante a gravidez. Descreve-se um caso de tumor desmóide de grandes proporções, localizado na parede abdominal, que surgiu a partir da 17ª semana em gestante sem antecedentes de polipose adenomatosa familial. A neoplasia foi totalmente extirpada utilizando-se prótese de polipropileno para reconstituição da parede abdominal. Atualmente a doente encontra-se bem, um ano após a cirurgia, em uso de antiinflamatório não hormonal para prevenção de recidivas.Desmoid tumors are neoplasms of the conjunctive tissue that are characterized by exclusive locoregional growth, frequent recurrence and minimal metastatic potential. They mainly affect individuals with familial adenomatous polyposis of the colon, and rarely occur isolated. The single form of this neoplasm most frequently appears in women of reproductive age, and during pregnancy. A case of a desmoid tumor of large proportions located in the abdominal wall is described. It appeared at the 17th week of pregnancy in a woman without any history of familial adenomatous polyposis. The neoplasm was totally extirpated, with the use of a polypropylene prosthesis for reconstitution of the abdominal wall. One year after the surgery, the patient continues to be well, while using non-steroidal anti-inflammatory drugs for the prevention of relapses.

    We determined the relevance of the biomechanical properties of freshly harvested vaginal tissue during large cystocele repair on clinical outcome at a minimum 1-year followup. With institutional review board approval we prospectively studied the biomechanical properties of full thickness vaginal wall tissue from postmenopausal women with symptomatic Baden-Walker prolapse undergoing anterior vaginal wall suspension with cystocele repair from 2002 to 2005. A standardized biomechanical protocol was applied with stress-strain curves for Young's modulus obtained by blinded investigators. Failed repair was defined as recurrence on examination or reoperation for recurrent anterior prolapse. A total of 32 patients (median age 72 years) had a median followup of 34 months (range 12 to 62). Median Young's modulus was statistically different in tissue samples transported in immersed vs moistened media (median 3.8 vs 7.6, p = 0.008). Associations between Young's modulus and clinical variables were described. On followup 7 patients experienced failure of the repair. After controlling for tissue transport protocol no association was seen between Young's modulus and failures (HR 1.1, p = 0.34). This study found no association between Young's modulus and clinical results at long-term followup. This finding suggests that retropubic scarring and pelvic floor muscle properties may be more important for a successful reparative outcome than the intrinsic properties of the vaginal wall. 2010 American Urological Association Education and Research, Inc.

    Full Text Available Los defectos abdominales congénitos de la línea media inferior, como la extrofia cloacal, se producen por fallos en el mesodermo entre la región umbilical y la membrana cloacal provocando severos defectos viscerales, musculares y óseos. Los reiterados intentos para la reconstrucción de los tractos intestinal y génitourinario en este tipo de malformaciones, pueden ocasionar secuelas graves en la pared malformada. La complejidad de esta malformación y los numerosos procedimientos a los que deben ser sometidos estos pacientes, requieren de un abordaje interdisciplinario desde el inicio del tratamiento y en cada una de las etapas reconstructivas a fin de evitar, al máximo, las lesiones de los tejidos abdominales para lograr, al final, una pared adecuada. Presentamos 2 casos de reconstrucción de la pared abdominal en sendos pacientes de sexo femenino con secuelas importantes de extrofia cloacal, utilizando tejidos expandidos, colgajos musculares y complementando el tratamiento en una de las pacientes con una malla protésica. En ambos casos, y a pesar de la falta de tejido provocada por la malformación y las secuelas de múltiples cirugías, obtuvimos un buen resultado funcional y estético.Abdominal congenital defects of the middle line have their origin in developmental faults of mesoderm between the umbilical region and the cloacal membrane, originating visceral, muscular and osseous defects in the abdominal wall. Repeated attempts to reconstruct the intestinal and genitourinary tract here and in other malformations, can cause serious sequeals in the previously deformed abdominal wall. We present 2 cases of abdominal wall reconstruction in patients with serious sequelae of cloacal extrophy. Complexity of this malformation calls for an interdisciplinary treatment to avoid the severe damage that may be caused during reconstructive attempts. In spite of lack of tissue because of the malformation and the sequelae of multiple surgeries we

    Metastasis from breast carcinoma is an uncommon occurrence in skeletal muscle, compared to local invasion into muscle from direct tumor spread. A 49-year-old woman was referred to our hospital with an 8.5-cm mass in the right breast. Core needle biopsy revealed metaplastic carcinoma with squamous metaplasia. The mass was rapidly growing and metaplastic, so mastectomy with dissection of axillary lymph nodes was performed. Pathological examination showed metaplastic carcinoma, histological grade 3, triple negative, and a MIB-1 labeling index of 80%. Six months postoperatively, during adjuvant chemotherapy treatment, she reported numbness and pain in the right lateral thigh and a mass in the right lower abdomen. Computed tomography revealed multiple lined masses in the abdominal wall and iliac muscle. Core needle biopsy showed metastatic breast carcinoma. Radio- and chemotherapy were administered, but the mass in the muscle became enlarged. To control her pain, a combined treatment with morphine, fentanyl, ketamine, antiepilepsy drug, and NSAIDs was administered. Liver metastasis appeared 9 months (15 months postoperatively) after recognition of muscle metastasis, and the patient died 16 months postoperatively. Skeletal muscle metastasis is uncommon, and therapeutic intervention is mainly palliative. The most common symptom of skeletal muscle metastasis is pain; thus, pain control is a pivotal goal of treatment.

    A 40-year-old man experienced a collision with a car while driving a motorcycle in which the car was in the opposite lane and made a right turn. The patient was thrown approximately 10 m from the point of collision and, as he exhibited a consciousness disturbance, was transferred to our department. He had a score of 13 on the Glasgow Coma Scale with sinus tachycardia on arrival. He showed guarding of the abdomen. A pan scan disclosed traumatic subarachnoid hemorrhage, intraventricular hemorrhage, fractures of the atlas, thoracic spine, sternum and left femur, and gas in the abdomen located just in front of the stomach. As the gas in the abdomen was initially judged to be free air, the patient underwent emergency laparotomy. However, no signs of perforation or injury were detected throughout the entire digestive tract. The accumulation of minute gas (vacuum phenomenon) occurs as traumatic impact. As representative mimics of free air were not observed during surgery in the present case, we believe that the traumatic impact to the patient's abdomen as a result of the collision caused the accumulation of gas in the abdominal wall due to vacuum phenomenon. Physicians should be aware of this clinical entity to accurately recognize the mechanism of gas formation in patients showing negative laparotomy findings for gas in the abdomen. This unique case adds additional information regarding the documented etiologies of mimics of pneumoperitoneum.

    In the past six years, there have been reports from abroad of an unexplained rise in the birth prevalence rate of the congenital abdominal wall defect gastroschisis, while rates for the macroscopically similar anomaly omphalocoele have remained stable. The Dublin EUROCAT Registry of congenital anomalies monitors trends in the birth prevalence of birth defects in the eastern region of Ireland. We analysed births of children with omphalocoele and gastroschisis born in the period 1981-2000, with comparisons of a number of demographic and obstetric variables. During the 20 year period the birth prevalence rate for omphalocoele remained stable at 2.5\\/10,000 births, whereas the rate for gastroschisis increased significantly during the 1990s from 1.0\\/10,000 in 1991 to 4.9\\/10,000 in 2000. Most of the increase occurred among mothers under 25 years of age. Omphalocoele was associated with a relatively high proportion of other major congenital anomalies. This study showed that there has been an unexpected rise in the birth prevalence of gastroschisis in the region, similar to that experienced in other countries in the same time period and likely to have common aetiological features.

    Malnutrition can be considered the most common disease in hospitals due to its high prevalence. To investigate the methods of evaluation of the nutritional status that better correlate with postoperative complications and the length of hospital stay in patients submitted to gastrointestinal or abdominal wall surgeries. This is a retrospective evaluation of 215 nutritional assessment records. All were submitted to traditional anthropometry (weight, height, BMI, arm circumference, triceps skinfold thickness and mid-arm muscle circumference), subjective global assessment, serum albumin and lymphocyte count. Nutritional risk index was also calculated. A total of 125 patients were included. Malnutrition was diagnosed by mid-arm muscle circumference, nutritional risk index and subjective global assessment in 46%, 88% and 66%, respectively. Severe malnutrition was found in 17,6% if considered subjective global assessment and in 42% by the nutritional risk index. Oncologic patients had a worst nutritional status according to this index (5,42 less units). There was a negative correlation between occurrence the noninfectious postoperative complications with the nutritional risk index (p=0,0016). Similarly, lower serum albumin levels were associated with higher non infectious complications (p=0,0015). The length of hospital stay was, in average, 14,24 days less in patients without complications as compared with non infectious postoperative complications (p<0,05). Nutritional risk index and serum albumin are the parameters with the best capacity to predict the occurrence of non infectious postoperative complications and the length of hospital stay was higher to this patients.

    A 25-year-old man, riding a motorcycle, rammed into a moving car at a T junction and sustained a blunt lower-right abdominal injury with the handlebar of his motorbike. He developed a swelling at the point of impact for which he presented in hospital 10 days later. Clinical assessment revealed a healthy young man with a soft, nontender reducible swelling over the lateral half of the right inguinal area. A diagnosis of acute traumatic hernia was made. Abdominal ultrasonography revealed a wide-necked defect in the anterior abdominal wall over the right inguinal area with protruding bowel loops beneath an intact skin. He was planned for herniorrhaphy but has defaulted since then.

    Granular cell tumors (GCTs) are extremely rare mesenchymal neoplasms of Schwann cell origin. Malignant GCTs (MGCTs) comprise 0.5-2% of all GCTs. In the present report, we describe a case of a 66-year-old man with MGCT of the abdominal wall. The patient visited our hospital due to a recently growing palpable soft tissue mass in the abdominal wall. Computed tomography scan revealed a 4.3 × 4.1 × 2.9 cm sized mass arising from the left abdominal wall, which was contemplated as a desmoid tumor before surgical excision. Histopathological examination confirmed MGCT.

    Full Text Available The presence of a contaminated surgical field in abdominal wall defects caused by trauma presents a challenge for surgeons. Both primary suture and synthetic meshes are strongly discouraged as surgical treatments in such cases. We describe the use of a porcine dermal collagen (Permacol implant in an eight-year-old patient with multiple injuries. Three months after discharge, the child remains well with good cosmetic results. He is free of pain and has returned to full activity levels with complete wound closure and without any evidence of residual hernia. In conclusion, our experience indicates that the use of Permacol can be considered an efficient technique for reconstructing an infected abdominal wall defect of a pediatric multitrauma patient.

    Full Text Available Intestinal atresia type III B (apple peel and gastroschisis are both congenital malformations who require early surgical correction in neonatal age. Their association is very rare. We present the case of a full term infant with partial apple peel ileal atresia and a small defect of the anterior abdominal wall, complicated by in utero intestinal perforation and subsequent meconial peritonitis. We observed a partial atresia of small intestine, with involvement of terminal ileus savings of jejunum and a large part of the proximal ileum, small anterior abdominal wall defect with herniation of few bowel loops, intestinal malrotation. Paralytic ileus and infections are the main causes of morbidity and mortality at neonatal age. In our case, in spite of the mild phenotype, prognosis has been complicated by the onset of functional bowel obstruction, caused by chemical peritonitis resulting from contact with either amniotic fluid and meconium.

    Full Text Available BackgroundIf a chronically infected abdominal wound develops, complications such as peritonitis and an abdominal wall defect could occur. This could prolong the patient's hospital stay and increase the possibility of re-operation or another infection as well. For this reason, a solution for infection control is necessary. In this study, surgery using a rectus abdominis muscle myofascial splitting flap was performed on an abdominal wall defect.MethodsFrom 2009 to 2012, 5 patients who underwent surgery due to ovarian rupture, cesarean section, or uterine myoma were chosen. In each case, during the first week after operation, the wound showed signs of infection. Surgery was chosen because the wounds did not resolve with dressing. Debridement was performed along the previous operation wound and dissection of the skin was performed to separate the skin and subcutaneous tissue from the attenuated rectus muscle and Scarpa's fascial layers. Once the anterior rectus sheath and muscle were adequately mobilized, the fascia and muscle flap were advanced medially so that the skin defect could be covered for reconstruction.ResultsUpon 3-week follow-up after a rectus abdominis myofascial splitting flap operation, no major complication occurred. In addition, all of the patients showed satisfaction in terms of function and esthetics at 3 to 6 months post-surgery.ConclusionsUsing a rectus abdominis myofascial splitting flap has many esthetic and functional benefits over previous methods of abdominal defect treatment, and notably, it enabled infection control by reconstruction using muscle.

    Full Text Available The active retrieval of methods for the increase of the efficiency of ventral hernia alloplasty is performed now; however the structural-functional changes of scar and muscle tissues during their reorganization are still little studied. The analysis of relationship of connective tissue with the hemomicrocirculation elements plays the important role for the understanding of the structural-functional condition of the anterior abdominal wall and also concrete mechanisms of reorganization of microvessels taking into account the dynamics of muscle-aponeurotic structures reconfiguration. The purpose of the current study was to determine the dynamics of structural-functional reconfiguration of microcircular and muscle-aponeurotic components, as well as connective tissue in the anterior abdominal wall after alloplasty of experimental ventral defect with the polypropylene monofilament net "Prolene". The quantitative morphological analysis was carried out during 1 year. The analysis of scar tissue formation and muscles reconfiguration in the anterior abdominal wall after plastic reconstruction of experimental defect allowed to reveal that the presence of polypropylene prosthetic device increases the duration of early inflammatory processes in a moderate degree, providing, however, adequate and full structural reconfiguration of scar and muscle tissue in the future, including microcirculation components.

    More challenging abdominal aortic aneurysms with unfavorable proximal aortic neck anatomy are treated with endovascular means. As a consequence, proximal inadequate sealing may result in type IA endoleak, which in turn can lead to abdominal aortic aneurysm progression or rupture. The presence of type IA endoleak is an indication for secondary interventions. External aortic banding can be a good option to solve a type IA endoleak, but is underreported in literature; we present two cases and review literature.

A técnica da transposição peritônio-aponeurótica longitudinal bilateral (técnica de Lázaro da Silva foi utilizada para as grandes hérnias incisionais. É uma técnica já consagrada, que consta de três planos de suturas sem superposição dos mesmos. Sua recidiva em cinco anos de seguimento tem sido em tomo de 5% segundo estudos do próprio autor. A grande vantagem técnica é que, usando o saco herniário (quanto maior e mais espesso, melhor como fechamento e reforço do anel, evita-se o uso de prótese com todos os inconvenientes da mesma (fístulas, rejeições etc. Uma variante desta técnica, para as hérnias com anel herniário de até 10cm, é proposta pelos autores, e consiste no fechamento do anel e reforço da sutura com o saco herniário, em jaquetão. A vantagem seria a facilidade de execução e diminuição do tempo operatório, além de evitar dissecções extensas das camadas aponeuróticas. Quando o anel herniário alcançar 10cm e existir ligeira tensão, deve-se realizar incisão relaxadora na aponeurose anterior dos retos e recobrir a superfície cruenta com o próprio saco herniário que deverá estar íntegro. Esta técnica ainda requer maior observação clínica.

    BACKGROUND: The role of the anterolateral abdominal wall muscles (AAWMs during the vesical filling and evacuation has not been sufficiently addressed in the literature. We have investigated the hypothesis that the AAWMs exhibit the increased electromyographic (EMG activity on the vesical distension and contraction which presumably assists vesical evacuation.

    METHODS: The effects of the vesical balloon distension on the vesical pressure (VP, vesical neck (VNP pressures and the AAWMs' EMG activity were studied in 28 healthy volunteers aged 40.7 ± 9.7 years (18 men, 10 women. These effects were tested after the individual anesthetization of the bladder and AAWMs and after saline infiltration.

    RESULTS: The VP and the VNP showed a gradual increase upon the incremental vesical balloon distension which started at a distending volume of 120–140 ml. At a mean volume of 364.6 ± 23.8 ml, the VP increased to a mean of 36.6 ± 3.2 cmH2O, the VNP decreased to 18.4 ± 2.4 cmH2O, and the AAWMs EMG registered a significant increase. This effect disappeared in the individual bladder and in the AAWMs' anesthetization. However, it did not disappear in the saline administration.

    CONCLUSIONS: The AAWMs appear to contract simultaneously with vesical contraction. This action presumably increases the IAP and it

    PurposeTo investigate the causes and results of late open surgical conversion (LOSC) after failed abdominal aortic aneurysm repair (EVAR) and to summarize our 17 years’ experience with 13 various endografts.MethodsRetrospective data from August 1994 to January 2011 were analyzed at our center. The various devices’ implant time, the types of devices, the rates and causes of LOSC, and the procedures and results of LOSC were analyzed and evaluated.ResultsA total of 1729 endovascular aneurysm repairs were performed in our single center (Nuremberg South Hospital) with 13 various devices within 17 years. The median follow-up period was 51 months (range 9–119 months). Among them, 77 patients with infrarenal abdominal aortic aneurysms received LOSC. The LOSC rate was 4.5 % (77 of 1729). The LOSC rates were significantly different before and after January 2002 (p < 0.001). The reasons of LOSC were mainly large type I endoleaks (n = 51) that were hard to repair by endovascular techniques. For the LOSC procedure, 71 cases were elective and 6 were emergent. The perioperative mortality was 5.2 % (4 of 77): 1 was elective (due to septic shock) and 3 were urgent (due to hemorrhagic shock).ConclusionLarge type I endoleaks were the main reasons for LOSC. The improvement of devices and operators’ experience may decrease the LOSC rate. Urgent LOSC resulted in a high mortality rate, while selective LOSC was relatively safe with significantly lower mortality rate. Early intervention, full preparation, and timely LOSC are important for patients who require LOSC.

    Objective To compare duplex ultrasound and computed tomography (CT) angiography in terms of their performance in detecting endoleaks, as well as in determining the diameter of the aneurysm sac, in the postoperative follow-up of endovascular abdominal aortic aneurysm repair. Materials and Methods This was a prospective study involving 30 patients who had undergone endovascular repair of infrarenal aortoiliac aneurysms. Duplex ultrasound and CT angiography were performed simultaneously by independent radiologists. Measurements of the aneurysm sac diameter were assessed, and the presence or absence of endoleaks was determined. Results The average diameter of the aneurysm sac, as determined by duplex ultrasound and CT angiography was 6.09 ± 1.95 and 6.27 ± 2.16 cm, respectively. Pearson's correlation coefficient showing a statistically significant correlation (R = 0.88; p < 0.01). Comparing the duplex ultrasound and CT angiography results regarding the detection of endoleaks, we found that the former had a negative predictive value of 92.59% and a specificity of 96.15%. Conclusion Our results show that there is little variation between the two methods evaluated, and that the choice between the two would have no significant effect on clinical management. Duplex ultrasound could replace CT angiography in the postoperative follow-up of endovascular aneurysm repair of the infrarenal aorta, because it is a low-cost procedure without the potential clinical complications related to the use of iodinated contrast and exposure to radiation.

    Until recently, the Cook Zenith aortic endograft (Cook Medical Inc, Bloomington, Ind) was the only device used for physician-modified fenestration because its constraining wire allowed physicians to reconstrain the device after modifications. Although the Cook Zenith fenestrated endograft has been approved by the Food and Drug Administration, it is currently not available in the majority of the hospitals and is not applicable to the patients who need urgent or emergent aneurysm repair. With the redesign of the Gore C3 delivery system, the Gore Excluder aortic stent graft (W. L. Gore & Associates, Inc, Flagstaff, Ariz) can now also be reconstrained, which makes it suitable for physician-modified fenestration. We describe the technique for modification and implantation of the Gore Excluder aortic stent graft in a patient requiring 2-vessel bilateral renal artery fenestration. This application provides an additional option for treatment of patients with abdominal aortic aneurysms who are anatomically unsuitable for conventional endovascular aneurysm repair and are at high risk for open repair.

    Objective: The aim of our retrospective study was to review our single-center experience with aortic abdominal aneurysm (AAA) repair retrospectively. Material and methods: From 1995 to 2005, 70 consecutive patients affected by AAA were treated by endovascular stent-graft repair. Mean follow-up was 23.9 months. Follow-up investigations were performed at 6 and 12 months and yearly thereafter. Five different stent-graft designs were compared to each other. Primary technical success (PTS), assisted primary technical success (APTS), primary clinical success (PCS) and secondary clinical success (SCS) were evaluated. Results: All over PTS was achieved in 94.3%, APTS in 97.1%, PCS in 61.4%, APCS in 64.3% and SCS in 70%. There were 3 type I endoleaks, 25 type II endoleaks, 4 type III endoleaks, 8 limb problems, 5 conversions to open surgery, 10 aneurysm sac expansions and 14 device migrations. Patients with newer generation devices showed better results than patients with first generation prosthesis. In addition results were better for grafts with suprarenal fixation (versus infrarenal fixation) and grafts with barbs and hooks (versus grafts without barbs and hooks). Patients with bad anatomic preconditions showed a higher complication rate. Conclusion: Contrary to first generation products, new stent-graft designs show acceptable technical and clinical results in endovascular AAA aneurysm repair. However, this therapy still should be reserved only for patients with significant comorbities and suitable anatomic conditions.

    In the last decades, the concept of earthquake resilient structural systems is becoming popular in which the rocking structure is considered as a viable option for buildings in regions of high seismicity. To this end, a novel wall-base connection based on the " repairable structure" approach is proposed and evaluated. The proposed system is made of several steel plates and high strength bolts act as a friction connection. To achieve the desired rocking motion in the proposed system, short-slotted holes are used in vertical directions for connecting the steel plates to the shear wall (SW). The experimental and numerical studies were performed using a series of displacement control quasi-static cyclic tests on a reference model and four different configurations of the proposed connection installed at the wall corners. The seismic response of the proposed system is compared to the conventional SW in terms of energy dissipation and damage accumulation. In terms of energy dissipation, the proposed system depicted better performance with 95% more energy dissipation capability compared to conventional SW. In terms of damage accumulation, the proposed SW system is nearly undamaged compared to the conventional wall system, which was severely damaged at the wall-base region. Overall, the introduced concept presents a feasible solution for R/C structures when a low-damage design is targeted, which can improve the seismic performance of the structural system significantly.

    Full Text Available A rare case of blunt traumatic abdominal hernia is presented in which jejunal loops herniated through the abdominal wall. The patient had a serious motor vehicle accident seven years ago, while wearing the seat belt. He developed a traumatic hernia in the anterior lateral abdominal wall, which was operated, and relapsed after some months. The patient was reoperated and we observed the unattachment of the anterior lateral abdominal musculature from the ilium crest. After the hernial sac treatment, the defect was solved with the use of a polypropylene mesh. The postoperative evolution was good and four months later there were no signs of recurrence. Traumatic abdominal hernia remains a rare clinical entity, despite the increase in blunt abdominal trauma. Traumatic abdominal wall hernia falls into two general categories: small lower quadrant abdominal defects, typically the result of blunt trauma with bicycle handlebars, and larger abdominal wall defects related to motor vehicle accidents. The diagnosis may be often established by the physical examination alone. Conventional radiology and computerized tomography usefulness have been proved. In the vast majority of cases, early repair is recommended. The appropriate treatment is the reduction of the herniated bowel into the abdomen, the debridment of nonviable tissues, and a primary tension free closure of the detect.

    Abdominal aortic aneurysms (AAAs) are very rare in pediatric patients and can rarely be associated with tuberous sclerosis (TS). Open surgery is the first-line therapy. We report our experience added by a review on current literature. A 9-year-old boy with TS and history of 2 earlier open repairs for AAA presented to our department with a recurrent juxtarenal aortic aneurysm. We performed a polytetraflourethylene patch plasty. Postoperative course was uneventful. After 8 months, reconstruction was stable, and no recurrent aneurysm developed. Recurrent aneurysms may develop after open surgery for TS-associated AAA. However, open surgery is the recommended therapy but requires special techniques and experience in pediatric patients. Copyright © 2016 Elsevier Inc. All rights reserved.

    2006-01-01

    A horseshoe kidney poses special problems during treatment of an abdominal aortic aneurysm (AAA), and there is much controversy about the most suitable method of repair. We report the case of a 65-year-old man with a horseshoe kidney, in whom an AAA was treated with a unibody bifurcated endograft. During the procedure, the two anomalous renal arteries were sacrificed. Although there was transient elevation of the creatinine levels, the patient was discharged with normal renal function and no endoleak from the accessory renal arteries. Thus, when two normal and two accessory renal arteries arise from the non-aneurysmatic proximal aortic neck, providing that preoperative kidney function is normal, it seems that the treatment can be safely carried out using an endovascular technique and excluding the accessory renal arteries. This case supports the feasibility of endovascular surgery for the treatment of AAA in the presence of a horseshoe kidney.

    Full Text Available Abstract Aim To report a case of severe respiratory depression with PCA fentanyl use simulating stroke in a patient who underwent routine elective endoluminal graft repair for abdominal aortic aneurysm (AAA Case presentation A 78-year-old obese lady underwent routine endoluminal graft repair for AAA that was progressively increasing in size. Following an uneventful operation postoperative analgesia was managed with a patient-controlled analgesia (PCA device with fentanyl. On the morning following operation the patient was found to be unusually drowsy and unresponsive to stimuli. Her GCS level was 11 with plantars upgoing bilaterally. A provisional diagnosis of stroke was made. Urgent transfer to a high-dependency unit (HDU was arranged and she was given ventilatory support with a BiPap device. CT was performed and found to be normal. Arterial blood gas (ABG analysis showed respiratory acidosis with PaCO2 81 mmHg, PaO2 140 mmHg, pH 7.17 and base excess -2 mmol/l. A total dose of 600 mcg of fentanyl was self-administered in the 16 hours following emergence from general anaesthesia. Naloxone was given with good effect. There was an increase in the creatinine level from 90 μmol/L preoperatively to 167 μmol/L on the first postoperative day. The patient remained on BiPap for two days that resulted in marked improvement in gas exchange. Recovery was complete.

    Full Text Available Abstract Background Obesity and serum C-reactive protein (CRP (a sensitive marker of inflammatory activity are associated with most chronic diseases. Abdominal adiposity along with age is the strongest determinant of baseline CRP levels in healthy subjects. The mechanism of the association of serum CRP with disease is uncertain. We hypothesized that baseline serum CRP is a marker of inflammatory responsiveness to injury and that abdominal adiposity is the main determinant of this responsiveness. We studied the effect of abdominal adiposity, age and other environmental risk factors for chronic disease on the CRP response to a standardised surgical insult, unilateral hernia repair to not only test this hypothesis but to inform the factors which must be taken into account when assessing systemic inflammatory responses to surgery. Methods 102 male subjects aged 24-94 underwent unilateral hernia repair by a single operator. CRP was measured at 0, 6, 24 and 48 hrs. Response was defined as the peak CRP adjusted for baseline CRP. Results Age and waist:hip ratio (WHR were associated both with basal CRP and CRP response with similar effect sizes after adjustment for a wide-range of covariates. The adjusted proportional difference in CRP response per 10% increase in WHR was 1.50 (1.17-1.91 p = 0.0014 and 1.15(1.00-1.31 p = 0.05 per decade increase in age. There was no evidence of important effects of other environmental cardiovascular risk factors on CRP response. Conclusion Waist:hip ratio and age need to be considered when studying the inflammatory response to surgery. The finding that age and waist:hip ratio influence baseline and post-operative CRP levels to a similar extent suggests that baseline CRP is a measure of inflammatory responsiveness to casual stimuli and that higher age and obesity modulate the generic excitability of the inflammatory system leading to both higher baseline CRP and higher CRP response to surgery.

    Full Text Available Abstract Metastasis to the abdominal wall including port sites after laparoscopic surgery for colorectal cancer is rare. Resection of metastatic lesions may lead to greater survival benefit if the abdominal wall metastasis is the only manifestation of recurrent disease. A 57-year-old man, who underwent laparoscopic surgery for advanced mucinous adenocarcinoma of the cecum 6 years prior, developed a nodule in the surgical wound at the lower right abdomen. Although tumor markers were within normal limits, the metastasis to the abdominal wall and abdominal cavity from the previous cecal cancer was suspected. An abdominal computed tomography scan did not provide detective evidence of metastasis. 18F-fluorodeoxyglucose positron emission/computed tomography (18F-FDG PET/CT was therefore performed, which demonstrated increased 18F-fluorodeoxyglucose uptake (maximum standardized uptake value: 3.1 in the small abdominal wall nodule alone. Histopathological examination of the resected nodule confirmed the diagnosis of metastatic mucinous adenocarcinoma. Prognosis of intestinal mucinous adenocarcinoma is reported to be poorer than that of non-mucinous adenocarcinoma. In conclusion, this case suggests an important role of 18F-FDG PET/CT in early diagnosis and decision-making regarding therapy for recurrent disease in cases where a firm diagnosis of recurrent colorectal cancer is difficult to make.

    The purpose of this study was to evaluate the technical feasibility and clinical efficacy of percutaneous transabdominal treatment of endoleaks after endovascular aneurysm repair. Between 2000 and 2007, six patients with type I (n = 4) or II (n = 2) endoleaks were treated by the percutaneous transabdominal approach using embolization with N-butyl cyanoacrylate with or without coils. Five patients underwent a single session and one patient had two sessions of embolization. The median time between aneurysm repair and endoleak treatment was 25.5 months (range: 0-84 months). Follow-up CT images were evaluated for changes in the size and shape of the aneurysm sac and presence or resolution of endoleaks. The median follow-up after endoleak treatment was 16.4 months (range: 0-37 months). Technical success was achieved in all six patients. Clinical success was achieved in four patients with complete resolution of the endoleak confirmed by follow-up CT. Clinical failure was observed in two patients. One eventually underwent surgical conversion, and the other was lost to follow-up. There were no procedure-related complications. The percutaneous transabdominal approach for the treatment of type I or II endoleaks, after endovascular aneurysm repair, is an alternative method when conventional endovascular methods have failed.

    Abdominal wall muscles have a unique morphology suggesting a complex role in generating and transferring force to the spinal column. Studying passive mechanical properties of these muscles may provide insights into their ability to transfer force among structures. Biopsies from rectus abdominis (RA), external oblique (EO), internal oblique (IO), and transverse abdominis (TrA) were harvested from male Sprague-Dawley rats, and single muscle fibers and fiber bundles (4-8 fibers ensheathed in their connective tissue matrix) were isolated and mechanically stretched in a passive state. Slack sarcomere lengths were measured and elastic moduli were calculated from stress-strain data. Titin molecular mass was also measured from single muscle fibers. No significant differences were found among the four abdominal wall muscles in terms of slack sarcomere length or elastic modulus. Interestingly, across all four muscles, slack sarcomere lengths were quite long in individual muscle fibers (>2.4 µm), and demonstrated a significantly longer slack length in comparison to fiber bundles (p muscle lengths. Titin molecular mass was significantly less in TrA compared to each of the other three muscles (p < 0.0009), but this difference did not correspond to hypothesized differences in stiffness.

    Objective: The purpose of this study is to investigate the value of susceptibility-weighted imaging (SWI) for the evaluation of cyclic morphological and hemorrhagic changes in abdominal wall endometriomas (AWE). Materials and methods: Fourteen patients with a total of 17 lesions who were admitted with complaints of abdominal wall mass and cyclic pain were evaluated by MRI. Patients were scanned during the first three days of the menstrual cycle and during the mid-cycle phase (day 13–15). In addition to conventional images SWI was performed. The signal changes within the lesions on SWI were compared and graded on both studies. Results: There was no significant difference in the size of the lesions in the early days of the menstruation compared to the mid-menstrual period. The SWI taken on mid-cycle phase showed that the center was hyperintense and the peripheral zone was hypointense in all lesions. A signal void related to increased blood and the shrinkage of complete disappearance of hyperintensity in the venter of the lesion was seen 15 (88%) of the 17 cases on the SWI series performed during the menstrual phase scan. Conclusion: SWI is a sensitive technique and has the capability to show hemorrhage and deposition of hemosiderin within the lesions. For patients suspected with AWE, valuable diagnostic findings may be obtained if the MRI examination including SWI is performed during the early and mid phase menstrual cycle.

  11. Tacrolimus does not affect early wound healing in a rodent model of bowel anastomoses and abdominal wall closure.

    Martine C M Willems

    Full Text Available BACKGROUND: Use of immunosuppressant drugs has been associated with complications in wound healing. The calcineurin inhibitor tacrolimus is thought to have a relatively low complication rate, but preclinical research has yielded contradictory data, prompting the current comprehensive study. METHODS: Three groups of 33 male Wistar rats received a daily subcutaneous dose of 0,5, 2 or 5 mg/kg tacrolimus. A control group received saline. On day 0 a resection of 1 cm ileum and 1 cm colon was performed, and end-to-end anastomoses were constructed. Ten rats of each group were killed on day 3 and day 5 and the remaining animals on day 7. Both anastomoses and the wound in the abdominal wall were analyzed. Wound strength was the primary outcome parameter. RESULTS: Mean strength of the abdominal wall increased significantly over time in all groups (p<0.0001. Both the breaking strength and the bursting pressure of the ileum and colon anastomoses followed the same pattern. No differences were observed between control and experimental groups. In addition, no consistent differences were found between groups regarding wound hydroxyproline content and the activities of matrix metalloproteinase-2 and -9. CONCLUSION: Tacrolimus does not affect early wound healing.

    Full Text Available Purpose. The aim of this study was to present abdominal wall reconstruction using a porcine vascular graft seeded with MSC (mesenchymal stem cells on rat model. Material and Methods. Abdominal wall defect was prepared in 21 Wistar rats. Acellular porcine-vascular grafts taken from aorta and prepared with Triton X were used. 14 aortic grafts were implanted in place, of which 7 grafts were seeded with rat MSC cells (Group I, and 7 were acellular grafts (Group II. As a control, 7 standard polypropylene meshes were used for defect augmentation (Group III. The assessment method was performed by HE and CD31 staining after 6 months. The mechanical properties have been investigated by Zwick&Roell Z0.5. Results. The strongest angiogenesis and lowest inflammatory response were observed in Group I. Average capillaries density was 2.75, 0.75, and 1.53 and inflammatory effect was 0.29, 1.39, and 2.72 for Groups I, II, and III, respectively. The means of mechanical properties were 12.74±1.48, 7.27±1.56, and 14.4±3.7 N/cm in Groups I and II and control, respectively. Conclusions. Cell-seeded grafts have better mechanical properties than acellular grafts but worse than polypropylene mesh. Cells improved mechanical and physiological properties of decellularized natural scaffolds.

    Endovascular aneurysm repair (EVAR) has become the preferred approach for the treatment of infrarenal abdominal aortic aneurysm (IRAAA) in detriment of open surgical repair (OSR). EVAR results in lower mortality rates within 30 days, but rates tend to be the same after longer periods. Moreover, reduced use of hospital resources with EVAR does not necessarily offset the costs of the endoprosthesis. We aimed, in this study, to estimate hospital expenses after OSR or EVAR, including early and late readmissions. Retrospective analysis of hospital expenses (2005-2012) with elective IRAAA surgeries performed in a tertiary hospital, including 127 patients divided into 2 groups, EVAR (n = 102) and OSR (n = 25). One perioperative death occurred in each group. EVAR interventions lasted 145 vs. 210 min of OSR (P hospitalization time differed significantly for EVAR (4 days) and OSR (8 days; P expenses with EVAR were US $53,080.95 and US $56,289.49, respectively. The median and mean expenses with OSR were US $37,116.04 and US $68,788.54, respectively. Early readmissions reached 11.2%. None of the OSR patients required late reinterventions, but 10 (9.9%) EVAR patients did, one of whom died. EVAR resulted in higher expenses with the exclusion of one outlier. Late reinterventions, with elevated costs, were only required by EVAR patients. Thus, when patients are eligible to undergo either intervention, OSR seems to have lower costs and better long-term results. Copyright © 2016 Elsevier Inc. All rights reserved.

    Renal transplant recipients requiring aortic reconstruction due to abdominal aortic aneurysm (AAA) pose a unique clinical problem. The concern during surgery is causing ischemic injury to the renal allograft. A variety of strategies for protection of the renal allograft during AAA intervention have been described including a temporary shunt, cold renal perfusion, extracorporeal bypass, general hypothermia, and endovascular stent-grafting. In addition, some investigators have reported no remarkable complications of the renal allograft without any specific measures. We treated a case of AAA in a patient with a renal allograft using a temporary aortofemoral shunt with good result. Since this technique is safe and effective, it should be considered in similar patients with AAA and previously placed renal allografts.

    Full Text Available Background. This paper presents unpublished clinical and economic data associated with open surgical repair (OSR in low risk (LR patients and how it compares with EVAR and OSR in high risk (HR patients with an AAA > 5.5 cm. Design. Data from a 1-year prospective observational study was used to compare EVAR in HR patients versus OSR in HR and LR patients. Results. Between 2003 and 2005, 140 patients were treated with EVAR and 195 with OSR (HR: 52; LR: 143. The 1-year mortality rate with EVAR was statistically lower than HR OSR patients and comparable to LR OSR patients. One-year health-related quality of life was lower in the EVAR patients compared to OSR patients. EVAR was cost-effective compared to OSR HR but not when compared to OSR LR patients. Conclusions. Despite a similar clinical effectiveness, these results suggest that, at the current price, EVAR is more expensive than open repair for low risk patients.

    The systemic inflammatory response syndrome (SIRS) is common after major surgery. We examine the dynamics of SIRS in AAA patients, and assess the impact of the number of SIRS criteria on patient outcome. Prospective study of 151 consecutive patients with AAA, undergoing repair electively, urgently or with rupture. SIRS scores and organ failure scores were recorded prospectively each day for all patients. Outcome measures included length of stay, evidence of organ failure and mortality. The majority of patients developed SIRS postoperatively. Elective patients with a cumulative SIRS score of > or =10 during postoperative days 1-4 were more likely to die, compared to patients with a SIRS score of SIRS late in the postoperative period (day 5-10) was associated with adverse outcome (death) in elective patients (p=0.01). The actual number of SIRS criteria present did not significantly correlate with either outcome or the incidence of organ failure. SIRS is common in patients undergoing AAA repair. The SIRS score provides useful information regarding a patient's physiological state. High SIRS scores, and the development of SIRS late in the postoperative period are associated with adverse outcome in elective patients, and can therefore be used as an indicator of potential problems.

    Ever since its introduction, the transverse rectus abdominis myocutaneous flap has become the mainstay of autologous breast reconstruction. However, concerns regarding donor site morbidity due to the breach of abdominal wall musculature integrity soon followed. Muscle-sparing techniques, eventually eliminating the muscle from the flap all-together with the deep inferior epigastric artery perforator flap, did not eliminate the problem of abdominal wall weakness. This led to the conclusion that motor innervation might be at fault. Studies have shown that even in the presence of an intact rectus abdominis muscle, and an intact anterior rectus sheath, denervation of the rectus abdominis muscle results in significant abdominal wall weakness leading to superior and inferior abdominal bulges, and abdominal herniation. Our aim was to establish a mathematical model to predict the location of the motor innervation to the rectus abdominis muscle, and thus provide surgeons with a tool that will allow them to reduce abdominal morbidity during deep inferior epigastric artery perforator and free muscle-sparing transverse rectus abdominis myocutaneous surgery. We dissected 42 cadaveric hemiabdomens and mapped the course of the thoracolumbar nerves. We then standardized and analyzed our findings and presented them as a relative map which can be adjusted to body type and dimensions. Our dissections show that the motor innervation is closely related to the lateral vascular supply. Thus, when possible, we support the preferred utilization of the medial vascular supply, and the preservation of the lateral supply and motor innervation.

    Therapeutic delays in cases of external incarcerated hernias typically result in increasing morbidity, mortality, and health expenditures. We investigated the diagnostic role of blood fibrinogen level, white blood count (WBC), mean platelet volume (MPV), and platelet distribution width (PDW) in patients with incarcerated hernia. Two groups, each containing 100 patients, were studied. Group A underwent elective, and group B underwent incarcerated and urgent external hernia repair. We observed high fibrinogen and WBC levels but low MPV and PDW values for patients in group B. Contrary to our expectations, we found lower MPV and PDW values in the complicated group than in the elective group. The morbidity rate and cost burden were higher in group B, and the results were statistically significant. Early operation should be recommended for patients with incarcerated external hernias if their fibrinogen and WBC levels are high.

    The purpose of our study was to evaluate the value of dual-source dual-energy CT with colored iodine overlay for detection of endoleaks after endovascular abdominal aortic aneurysm repair. We also calculated the potential dose reduction by using a dual-energy CT single-phase protocol. From November 2007 to November 2009, 74 patients underwent CT angiography 2-7 days after endovascular repair during single-energy unenhanced and dual-energy venous phases. By using dual-energy software, the iodine overlay was superimposed on venous phase images with different percentages ranging between 0 (virtual unenhanced images) and 50-75% to show the iodine in an orange color. Two blinded readers evaluated the data for diagnosis of endoleaks during standard unenhanced and venous phase images (session 1, standard of reference) and virtual unenhanced and venous phase images with colored iodine overlay images (session 2). We compared the effective dose radiation of a single-energy biphasic protocol with that of a single-phase dual-energy protocol. The diagnostic accuracy of session 2 was calculated. The mean dual-energy effective dose was 7.27 mSv. By using a dual-energy single-phase protocol, we obtained a mean dose reduction of 28% with respect to a single-energy biphasic protocol. The diagnostic accuracy of session 2 was: 100% sensitivity, 100% specificity, 100% negative predictive value, and 100% positive predictive value. Statistically significant differences in the level of confidence for endoleak detection between the two sessions were found by reviewers for scores 3-5. Dual-energy CT with colored iodine overlay is a useful diagnostic tool in endoleak detection. The use of a dual-energy single-phase study protocol will lower radiation exposure to patients.

    Background:Endovascular aneurysm repair (EVAR) is one of the first-line therapies of abdominal aortic aneurysms.Postoperative endoleak is the most common complication of EVAR.Computed tomography angiography (CTA),which is routine for follow-up,has side effects (e.g.,radiation) and also has a certain percentage of missed diagnosis.Preliminary studies on contrast-enhanced ultrasound (CEUS) have shown that the sensitivity of CEUS for detecting endoleak is no lower than that of CTA.To investigate the advantages of CEUS,we conducted CEUS examinations of post-EVAR cases in which CTA failed to detect endoleak or could not verify the type of endoleak.Methods:Post-EVAR patients,who were clinically considered to have endoleak and met the inclusion criteria were enrolled between March 2013 and November 2014.All of the patients underwent color Doppler flow imaging (CDFI) and a CEUS examination.Size,location,microbubble dispersion,and hemodynamic characteristics of leaks were recorded.Comparison between the diagnosis of CEUS and CDFI was conducted using Fisher's exact test and clinical outcomes of all patients were followed up.Results:Sixteen patients were enrolled,and 12 (75%) had endoleaks with verified types by CEUS.Among 12 cases of endoleaks were positive by CEUS,10 were CDFI-positive,and the four CEUS-negative cases were all negative by CDFI.The diagnostic values of CEUS and CDFI were statistically different (P =0.008).Six patients with high-pressure endoleaks received endovascular re-intervention guided by CEUS results.One patient with type Ⅲ endoleak had open surgery when endovascular repair failed.Conclusions:CEUS is a new,safe,and effective means for detection ofendoleaks post-EVAR.This technique can be used as a supplement for routine CTA follow-up to provide more detailed information on endoleak and its category.

The cumulative rates of perioperative complications were 16% and 6.5%, respectively (P=0.001. The rate of reinterventions at 60 months was significantly higher in group 2 than in group 1 (29.1% and 20.1% respectively, P=0.03, log rank 4.6. Also the 5-year rate of endoleak was significantly greater in group 2 than group 1 (43.3% and 34.5% respectively, P<0.001, log rank 13.4; however, the rate of endoleaks requiring a redo procedure was lower in group 2 (35/163, 21.5% than in group 1 (51/108, 47%; P<0.001.Conclusion: Data from our study confirm that a DUS-based follow-up program in patients undergoing EVAR is equally sensitive in identifying endoleaks to the CT scan-based program used in past years.Keywords: duplex ultrasound, contrast-enhanced, endovascular aneurysm repair

    Purpose: To describe the findings on computed tomography (CT) of the aortic sac (AS) in patients operated on for abdominal aortic aneurysm (AAA) with insertion of a coated Dacron prosthesis. Material and Methods: A prospective study of 36 consecutive patients operated on for AAA over 2 years and followed longitudinally with CT for up to 10 years. Results: All patients had a fluid-filled AS on CT 7-10 days postoperatively. At 6 months, the AS had decreased in most patients, mainly in the antero-posterior diameter, and in two had disappeared completely. In five patients with complications, the AS increased in size. The AS disappeared completely at 10 years' follow-up in 13 patients. When present, a retroperitoneal hematoma always disappeared after 6 months. Conclusion: These data indicate that the AS after graft implantation will diminish gradually but will persist for at least 6 months. Usually the transverse diameter is bigger than the antero-posterior diameter. If the AS enlarges and becomes rounded and distended with an inhomogeneous interior, it might be a sign of graft infection. In these cases an ultrasound-guided or CT-guided puncture is recommended.

    Between 1977 and 1995, 19 children with portal hypertension (nine extrahepatic, ten intrahepatic) were treated by transpositioning the spleen into the left abdominal wall. Among the patients with intrahepatic portal hypertension three died. Two patients underwent secondary diminuition of the transposed spleen due to relapsed hypersplenism. In one of our first patients the transposed spleen atrophied after tangential resection. All surviving patients except one preserved hepatic function. The serum colloid osmotic pressure was stable. Plasma ammonia levels were normal. Serum immunoglobulins (IgG, IgM, IgA and IgG subclasses) and complement components (C3c, C4) were analyzed. After transposition patients had normal or slightly elevated values of these proteins compared with controls.

    Full Text Available We describe the case of an 83-year-old patient requiring repair of a large symptomatic abdominal aortic aneurysm (AAA. The patient was known to have coronary artery disease (CAD with symptoms and signs of significant myocardial dysfunction, left-heart failure, and severe aortic insufficiency. The procedure was performed with the help of both mechanical and pharmacological circulatory support. Distal perfusion was provided by an axillofemoral bypass with a centrifugal pump, with dobutamine and levosimendan administered as pharmacological inotropic support. The patient's hemodynamic status was monitored with continuous cardiac output monitoring and transesophageal echocardiography. No serious circulatory complications were recorded during the perioperative and postoperative periods. This paper suggests a potential novel approach to combined circulatory support in patients with heart failure, scheduled for open abdominal aortic aneurysm repair.

    Full Text Available Objective: To compare the survival and post-op complications following primary closure of perforated peptic ulcer by omental patch technique in 4 groups of patients as follows: two-drain group, one-drain subhepatic group, one-drain pelvic group and no-drain group. Methods: This is a prospective case-controlled clinical study performed in the Jawaharlal Nehru Medical College Hospital, Aligarh Muslim University, Aligarh, India. A total of 114 patients with perforated peptic ulcer who underwent emergency laparotomy with primary closure by omental patch technique were studied in 4 groups as mentioned above. Tube drains were used throughout the study. Results: Mean age of patients was 45±12.7 years (range 15- 75 with M:F ratio of 5:1. Clinical profile of patients matched in the 4 groups. Post-operative fever, vomiting, laparotomy wound infection, wound dehiscence and intraperitoneal collection were significantly lower in the no-drain group as compared to drain groups. There was found no significant difference between the no-drain and drain groups with respect to the post-operative abdominal distension, pain, intraabdominal sepsis, gastro-intestinal leak, adult respiratory distress syndrome and mortality. Drain-related complications were recorded in 36.8% of patients with tube drain(s. Conclusion: Peptic perforation closure with omental patch technique is safe without prophylactic drainage and a high rate of drain-related morbidity negates the concept of the routine drainage after this procedure. One drain placement is as good as the two drain placement and sub-hepatic drain is more useful than the pelvic drain. [J Exp Integr Med 2012; 2(1.000: 47-54

    The purpose of this study was to determine whether surgeons without formal radiological training are able to assess suitability of patients with ruptured abdominal aortic aneurysms (AAA) for EVAR. The CT scans of 20 patients with AAA were reviewed under timed conditions by six vascular surgeons. Twenty minutes was allocated per scan. They were asked to determine if each aneurysm would be treatable by EVAR in the emergency setting and, if so, to measure for device selection. The results were then compared with those of a vascular radiologist. Six surgeons agreed on the suitability of endovascular repair in 45% of cases (95% CI, 23.1-68.5%; 9/20 scans; kappa = 0.41 [p = 0.01]) and concurred with the radiologist in eight of these. Individually, agreement ranged from 13 to 16 of the 20 scans, 65-80% between surgeons. The kappa value for agreement between all the surgeons and the radiologist was 0.47 (p = 0.01, moderate agreement). For the individual surgeons, this ranged from 0.3 to 0.6 (p = 0.01). In conclusion, while overall agreement was moderate between the surgeons and the radiologist, it is clear that if surgeons are to assess patients for ruptured EVAR in the future, focused training of surgical trainees is required.

    Purpose To determine the clinical and epidemiological characteristics of abdominal wall endometriosis (AWE), as well as the rate and recurrence factors for the disease. Methods A retrospective study of 52 women with AWE was performed at Universidade Estadual de Campinas from 2004 to 2014. Of the 231 surgeries performed for the diagnosis of endometriosis, 52 women were found to have abdominal wall endometriosis (AWE). The frequencies, means and standard deviations of the clinical characteristics of these women were calculated, as well as the recurrence rate of AWE. To determine the risk factors for disease recurrence, Fisher's exact test was used. Results The mean age of the patients was 30.71 ± 5.91 years. The main clinical manifestations were pain (98%) and sensation of a mass (36.5%). We observed that 94% of these women had undergone at least 1 cesarean section, and 73% had used medication for the postoperative control of endometriosis. The lesion was most commonly located in the cesarean section scar (65%). The recurrence rate of the disease was of 26.9%. All 14 women who had relapsed had surgical margins compromised in the previous surgery. There was no correlation between recurrent AWE and a previous cesarean section (p = 0.18), previous laparotomy (p = 0.11), previous laparoscopy (p = 0.12) and postoperative hormone therapy (p = 0.51). Conclusion Women with previous cesarean sections with local pain or lumps should be investigated for AWE. The recurrence of AWE is high, especially when the first surgery is not appropriate and leaves compromised surgical margins. Thieme Revinter Publicações Ltda Rio de Janeiro, Brazil.

    2009-01-01

    This paper studies the seismic performance of FRP-strengthened RC interior non-seismically detailed beam-wide columns and beam-wall joints after limited seismic damage. Four eccentric and concentric beam-wide column joints and two beam-wall joints, initially damaged in a previous study, were repaired and tested under constant axial loads (0. \\fc'Ag and 0. 35 fc'Ag ) and lateral cyclic loading. The rapid repair technique developed, aimed to restore the original strength and to provide minimum drift capacity. The repair schemes were characterized by the use of; (a) epoxy injections and polymer modified cementitious mortar to seal the cracks and replace spalled concrete; and (b) glass (GFRP) and carbon (CFRP) sheets to enhance the joint performance. The FRP sheets were effectively prevented against possible debonding through the use of fiber anchors. Comparison between responses of specimens before and after repair clearly indicated reasonable restoration in strength, drift capacity, stiffness and cumulative energy dissipation capacity. All specimens failed with delamination of FRP sheets at beam-column joint interfaces. The rapid repair technique developed in this study is recommended for mass upgrading or repair of earthquake damaged beam-column joints.

    AIM: To evaluate the positive predictive value of abdominal non-prepared computed tomography (CT) for diagnosing intestinal lumen or wall lesions in patients presenting to the emergency room (ER) with abdominal complaints.METHODS: For 1-year we prospectively evaluated all ER patients hospitalized after abdominal CT scan detected either intraluminal or intestinal wall lesions. These patients underwent colonoscopy serving as gold standard. Patients with prior abdominal pathology or CT findings of appendicitis or diverticulitis were excluded.RESULTS: Five hundred and sixty-eight abdominopelvic CT scans were performed in the ER, 96 had positive colonic findings. Sixty-two patients were excluded, 46 because of diverticulitis or appendicitis, 16 because of prior abdominal pathology. Of the remaining 34 patients, 14 did not undergo colonoscopy during hospitalization.Twenty eligible patients were included in the study. The positive predictive value of the CT scans performed in the ER was calculated to be 45% (95% CI 25-67).CONCLUSION: CT findings correlated with colonoscopic findings only in approximately half of the cases. Relying on non-prepared CT scan findings in planning patient management and colonoscopy may lead to unnecessary diagnostic work-ups.

    Background The aim of the study was to test the hypothesis that in patients with chronic complex sternum dehiscence, the use of muscle flap repair minimizes the occurrence of paradoxical motion of the chest wall (CWPM) when compared to sternal rewiring, eventually leading to better respiratory function and clinical outcomes during follow-up. Methods In a propensity score matching analysis, out of 94 patients who underwent sternal reconstruction, 20 patients were selected: 10 patients underwent sternal reconstruction with bilateral pectoralis muscle flaps (group 1) and 10 underwent sternal rewiring (group 2). Eligibility criteria included the presence of hemisternum diastases associated with multiple (≥3) bone fractures and radiologic evidence of synchronous chest wall motion (CWSM). We compared radiologically assessed (volumetric computed tomography) ventilatory mechanic indices such as single lung and global vital capacity (VC), diaphragm excursion, synchronous and paradoxical chest wall motion. Results Follow-up was 100% complete (mean 85±24 months). CWPM was inversely correlated with single lung VC (Spearman R=−0.72, p=0.0003), global VC (R=−0.51, p=0.02) and diaphragm excursion (R=−0.80, p=0.0003), whereas it proved directly correlated with dyspnea grade (Spearman R=0.51, p=0.02) and pain (R=0.59, p=0.005). Mean CWPM and single lung VC were both better in group 1, whereas there was no difference in CWSM, diaphragm excursion and global VC. Conclusion Our study suggests that in patients with complex chronic sternal dehiscence, pectoralis muscle flap reconstruction guarantees lower CWPM and greater single-lung VC when compared with sternal rewiring and it is associated with better clinical outcomes with less pain and dyspnea.

    Chronic muscle wasting, or sarcopenia, has been associated with poor-health outcomes after major surgical procedures. Here, we explore the utility of CT-generated determinations of sarcopenia as markers of risk in patients undergoing evaluation for complex ventral hernia repair. In 148 successive patients being evaluated for complex ventral hernia repair, CT scans were analyzed retrospectively for attributes of the hernia and indices of core-muscle mass, correlating them with preoperative clinical/laboratory profiles and outcomes in 82 patients who had undergone surgery. Prevalence of sarcopenia, and sarcopenia corrected for obesity, was 26% and 20% respectively. Sarcopenia was associated with age, some laboratory indicators, and increased hospital length of stay but not with a higher likelihood of surgical site occurrence. Obesity may obscure the value of sarcopenia as a marker of metabolic disturbance and postoperative outcome. Image-based measurements of core-muscle mass should be used with caution as predictors of risk in similar surgical populations. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available Abstract Background Cases with subcutaneous metastasis of differentiated hepatocellular carcinoma to the abdominal wall without prior seeding as a consequence of local interventions with a negative or normal alpha-fetoprotein level in the serum are extremely rare. Case report This is the first report of a case with AFP-negative, differentiated hepatocellular carcinoma metastasis to the abdominal wall within a pre-existing subcutaneous lipoma since childhood after antiandrogen therapy with leuprorelin and buserelin acetate for prostate cancer without seeding. Methods Clinical features including histology, immunohistochemistry, clinical course and surgical approach are presented. Results Histological examination revealed a hepatocellular carcinoma with a trabecular and pseudoglandular growth pattern with moderately atypical hepatocytes with multifocal bile formation within a lipoma. The postoperative course of abdominal wall reconstruction with a monocryl-prolene mesh and a local flap after potentially curative resection was uncomplicated. Discussion and conclusion It may be that previous antiandrogen treatment for prostate carcinoma contributed to the fact that our patient developed alpha-fetoprotein-negative and androgen receptor-negative subcutaneous abdominal wall metastasis within a pre-existing lipoma since childhood.

    Surgical management of posterior vaginal wall prolapse has variable functional outcomes. Synthetic and biological grafts are used to improve outcomes and reduce failures. The objective of this study was to determine the functional outcomes and its implications on patient-reported quality of life of a technique of posterior vaginal wall repair and prespinous colpopexy with biological small intestinal submucosal (SIS) graft in the management of posterior vaginal wall prolapse. This prospective cohort study was conducted in a urogynaecology subspecialty center in the UK. Women with moderate degree rectocele or more, with or without other compartmental prolapse underwent posterior vaginal wall repair and prespinous colpopexy with SIS graft over a 3-year period. ICIQ vaginal symptoms questionnaires were used pre-operatively and at 6 months post-operatively to assess functional outcomes. The Wilcoxon signed R test was used to analyze the results. 50 women underwent posterior repair with SIS graft (27 with concomitant procedures). There was a statistically significant improvement (p < 0.0001) in the vaginal symptoms and sexual matters scores at 6-month follow-up in all the women. The quality of life scores also improved significantly (p < 0.0001) in all the women. Concomitant pelvic surgery did not affect the outcomes (p < 0.0001). There were no significant intra- or post-operative complications. Posterior vaginal wall repair and prespinous colpopexy with biological SIS graft is an effective surgical option for managing women with posterior vaginal wall prolapse with or without other concomitant compartmental defects.

    We report a case of gastric penetration caused by accidental ingestion of a chicken bone in a 42-year old woman with a partially wearing denture. Three days ago, she accidentally swallowed several lumps of poorly-chewed chicken. Physical examination disclosed mild tenderness in the periumbilical area. Abdominal Computed tomography (CT) showed a suspicious penetration or perforation of the stomach wall measuring about 3 cm, by a linear radiopaque material at the lesser curvature of the antrum. The end of a chicken bone was very close to but did not penetrate the liver. Endoscopic examination revealed a chicken bone that penetrated into the prepyloric antrum. The penetrating chicken bone was removed with grasping forceps. Five endoscopic clips were applied immediately at the removal site and the periumbilical pain resolved promptly. After removal of the chicken bone, the patient was treated with conservative care for three days, after which she was completely asymptomatic and discharged without complication. To treat gastric penetration by a foreign body, endoclipping can be a useful method in patients with no signs or symptoms of peritoneal irritation.

    To describe the incidence and treatment of prevascular and retropsoas hernias in a large-volume general surgery practice. Femoral hernias are considered uncommon with an incidence between 2 and 8 % of groin hernias. There are no large studies describing the subtypes of femoral hernias or retropsoas hernias, and therefore no reported incidence or standardized treatment recommendations for these hernias exist. This study is a retrospective review of all patients undergoing total extraperitoneal (TEP) laparoscopic herniorrhaphy between August 1993 and December 2011. A single surgeon performed all the repairs. Demographics and patient outcomes were reported. 2,436 patients underwent 3,242 TEP repairs. The subtypes were: indirect 1,523 (46.9 %), direct 1,473 (45.4 %), femoral 156 (4.8 %), obturator 35 (1.1 %), prevascular 25 (0.77 %), Spigelian 20 (0.61 %), retropsoas 3 (0.09 %). Prevascular hernias accounted for 16 % of femoral hernias. Patients with prevascular hernias had a mean age of 70.3 years and were all male. 13 of the 25 patients (52 %) with prevascular hernias had other associated defects and four (16 %) of the patients had prevascular hernias as a recurrence from a prior hernia operation. There were three patients with retropsoas hernias that only would not have been seen from an anterior open approach. There are no intraoperative complications or known recurrences from this study group. Prevascular and retropsoas hernias are uncommon, but have a higher incidence than previously believed. Prevascular hernias tend to be associated with older age and other defects. The diagnosis and management of these hernias are readily achieved using the laparoscopic TEP approach.

    To measure abdominal wall thickness to determine the depth at which the renal vascular bed and mesenteric vascular bed are located, and to determine the appropriate site for placement of near-infrared spectroscopy probes for accurate monitoring regional oxygen saturation index in children. Abdominal computerized tomography scans in children were used to measure the abdominal wall thickness and to ascertain the location of kidneys. Tertiary care children's hospital. Children 0-18 yrs of age; n = 38. None. The main mass of the kidneys is located between vertebral levels T12 and L2 on both sides. The left kidney is located about a half-vertebral length higher than the right kidney. Posterior abdominal wall thickness ranged from 6.6 to 115.8 mm (median, 22.1 mm). Posterolateral abdominal wall thickness ranged from 6.7 to 114.5 mm (median, 19.6 mm). Anterior abdominal wall thickness in the supraumbilical level ranged from 3.5 to 62.9 mm (median, 16.0 mm). All abdominal wall thicknesses correlated better with weight of the subjects than their age. Abdominal wall thickness potentially exceeds the sampling depth of currently used near-infrared spectroscopy probes above a certain body size. Application of current near-infrared spectroscopy probes and design of future probes should consider patient size variations in the pediatric population.

    Background. Repeat volumetric analysis of abdominal aortic aneurysm (AAA) after endovascular AAA repair (EVAR) is time-consuming and requires advanced processing, dedicated equipment, and skilled operators. Purpose. To clarify the validity of measuring the maximal short-axis diameter (Dmax) of AAA in follow-up non-enhanced axial CT as a means of detecting substantial endoleaks after EVAR. Material and Methods. CT images were retrospectively reviewed in 47 patients (7 women, 40 men; mean age, 76.2 years) who had no endoleak on initial contrast-enhanced CT after EVAR. Regular follow-up CT studies were performed every 6 months. At each CT study, the Dmax on the CT axial image was measured and compared with that on the last CT (115 data-sets). Contrast-enhanced CT was regarded as the standard of reference to decide the presence or absence of endoleaks. The appearance of endoleak was defined as the end point of this study. Results. Endoleaks were detected in 17 patients during the follow-up period. Mean Dmax changes for 6 months were significant between positive and negative endoleak cases (1.8 {+-} 1.9 vs. -1.1 {+-} 3.0 mm, P < 0.0001). When the Dmax change {<=} 0 mm for 6 months was used as the threshold for negative endoleak, the sensitivity, specificity, positive predictive value, and negative predictive value were 74.5, 82.4, 96.1, and 35.9%, respectively. When Dmax change {<=}-1 mm was used as the threshold, the sensitivity, specificity, PPV, and NPV were 38.8, 100, 100, and 22.1%, respectively. Conclusion. Contrast-enhanced CT is not required for the evaluation of endoleaks when the Dmax decreases by at least 1 mm over 6 months after EVAR.

    Full Text Available PURPOSE: To evaluate the healing process of a defect in the ventral abdominal wall of rats, comparing the polypropylene and polypropylene/poliglecaprone meshes on the 30th and 60th postoperative day. METHODS: Thirty two Wistar rats were submitted to a ventral abdominal wall defect, with integrity of the parietal peritoneum. In the repair, were used polypropylene (group A and polypropylene/poliglecaprone (group B meshes. The groups were subdivided into four subgroups of eight animals euthanized on the 30th (A30 and B30 and 60th postoperative day (A60 and B60. Fragments of the abdominal wall of the animals were submitted to macroscopic, tensiometric and histological evaluations. RESULTS: The tensiometry on subgroup A30 showed a mean average break point of 0.78 MPa and in A60, 0.66 Mpa. In subgroup B30 it was 0.84 MPa and in B60, 1.27 Mpa. The score of the inflammatory process showed subacute phase on A30 and B30 sub-groups and chronic inflammatory process in subgroups A30 and 60B. CONCLUSIONS: The tensile strength was higher on the wall repaired by polypropylene/poliglecaprone mesh in the 60th post-operative day. Histology showed higher concentration of fibrosis on the surface of the polypropylene mesh with a tendency to encapsulation. In polypropylene/poliglecaprone subgroups the histology showed higher concentration of fibrosis on the surface of mesh filaments.OBJETIVO: Avaliar a cicatrização de um defeito, na parede abdominal ventral de ratos, comparando-se as telas de polipropileno e polipropileno/poliglecaprone no 30º e 60º dia do pós-operatório. MÉTODOS: Trinta e dois ratos Wistar foram submetidos à produção de defeito na parede abdominal ventral, com integridade do peritônio parietal. Na correção foram utilizadas as telas de polipropileno (grupo A e polipropileno/poliglecaprone (grupo B. Houve subdivisão em quatro subgrupos (A30, A60, B30 e B60 de oito animais que foram submetidos à eutanásia no 30º e 60º dia do p

    Full Text Available CONTEXTO: A incidência de hérnia incisional no pós-operatório da correção aberta de aneurisma de aorta abdominal é alta, variando de 10 a 37% e mais de três vezes mais comum do que em pacientes submetidos à correção para doença obstrutiva aorto-ilíaca. OBJETIVO: Apresentar a incidência de hérnia incisional em um grupo de pacientes acompanhados no pós-operatório da correção aberta de aneurisma de aorta abdominal. MÉTODOS: Série de casos em uma população de 144 pacientes operados por aneurisma de aorta abdominal, entre junho de 1989 e junho de 2010, e que estão em acompanhamento regular no Ambulatório de Moléstias Vasculares. RESULTADOS: O seguimento médio dos pacientes foi de 63 meses (1 a 238. A idade média foi de 67 anos (45 a 91 e o tamanho médio dos aneurismas foi de 6,54 cm. Foram realizadas 130 laparotomias medianas xifo-púbicas e 13 acessos extraperitoniais pelo flanco esquerdo. Nestes pacientes, a incidência de hérnia incisional foi de 18,5 e 7,7%, respectivamente, para incisões na linha média ou no flanco (p=0,315. Um paciente apresentou abaulamento da musculatura oblíqua por denervação. Foi realizada uma laparotomia transversa, que não apresentou hérnia no pós-operatório tardio. CONCLUSÕES: A incidência de hérnia incisional na cirurgia aberta para correção de aneurisma de aorta abdominal é alta, ocorre com maior frequência em incisões da linha média e tem relação direta com a técnica empregada para o fechamento da aponeurose, exigindo do cirurgião atenção especial para este tempo cirúrgico para evitar a causa mais comum de reoperação em tal grupo de pacientes.BACKGROUND: The incidence of incisional hernia in the post operatory of patients submitted to open abdominal aortic aneurysm repair is high, ranging from 10 to 37%, and is more than three times higher than the incidence of hernias in patients operated for aorto-iliac occlusion. OBJECTIVE: To evaluate the incidence of

    Background Although it is generally acknowledged that patients with ruptured abdominal aortic aneurysm (rAAA)obtain the greatest benefit from endovascular repair (EVAR),convincing evidence on the medium-long term effect is lacking.The aim of this study was to compare and summarize published results of rAAA that underwent EVAR with open surgical repair (OSR).Methods A search of publicly published literature was performed.Based on an inclusion and exclusion criteria,a systematic meta-analysis was undertaken to compare patient characteristics,complications,short term mortality and medium-long term outcomes.A random-effects model was used to pool the data and calculate pooled odds ratios and weighted mean differences.A quantitative method was used to analyze the differences between these two methods.Results A search of the published literature showed that fourteen English language papers comprising totally 1213 patients with rAAA (435 EVAR and 778 OSR) would be suitable for this study.Furthermore,13 Chinese studies were included,including 267 patients with rAAA totally,among which 238 patients received operation.The endovascular method was associated with more respiratory diseases before treatment (OR=1.81,P=0.01),while there are more patients with hemodynamic instability before treatment in OSR group (OR=1.53,P=0.031).Mean blood transfusion was 1328 ml for EVAR and 2809 ml for OSR (weighted mean difference (WMD) 1500 ml,P=0.014).The endovascular method was associated with a shorter stay in intensive care (WMD 2.34 days,P <0.001) and a shorter total postoperative stay (WMD 6.27 days,P <0.001).The pooled post-operative complication rate of respiratory system and visceral ischemia seldom occurred in the EVAR group (OR=0.48,P <0.001 and OR=0.28,P=0.043,respectively).The pooled 30-day mortality was 25.7% for EVAR and 39.6% for OSR,and the odds ratio was 0.53 (95% confidence interval (CI) 0.41-0.70,P <0.001).There was not,however,any significant reduction in

    Surgery or interventional therapy has some risks in the treatment of cerebral aneurysm. We established an internal carotid artery aneurysm model by dripping elastase in the crotch of the right internal and external carotid arteries of New Zealand rabbits. Following model induction, lentivirus carrying basic fibroblast growth factor was injected through the ear vein. We found that the longer the action time of the lentivirus, the smaller the aneurysm volume. Moreover, platelet-derived growth factor expression in the aneurysm increased, but smooth muscle 22 alpha and hypertension-related gene 1 mRNA expression decreased. At 1, 2, 3, and 4 weeks following model establishment, following 1 week of injection of lentivirus carrying basic fibroblast growth factor, the later the intervention time, the more severe the blood vessel damage, and the bigger the aneurysm volume, the lower the smooth muscle 22 alpha and hypertension-related gene 1 mRNA expression. Simultaneously, platelet-derived growth factor expression decreased. These data suggest that recombinant lentivirus carrying basic fibroblast growth factor can repair damaged cells in the aneurysmal wall and inhibit aneurysm dynamic growth, and that the effect is dependent on therapeutic duration.

    Intraoperative changes in circulatory hemodynamics and autonomic nervous activity were evaluated in 33 patients with cholelithiasis who underwent laparoscopic cholecystectomy. Of these patients, 18 were treated using a pneumoperitoneum (group G) and 15 using the abdominal wall-lifting method (group WL). Their ECG, blood pressure, arterial oxygen saturation, and expiratory carbon dioxide partial pressure were monitored. Autonomic nervous function was evaluated by spectral analysis of the heart rate. Mean blood pressure increased significantly in group G during surgery, but did not vary in group WL during any stage of surgery. The high-frequency (HF) power, an index of parasympathetic activity, decreased significantly in group G after pneumoperitoneum. However, the HF power did not decrease significantly in group WL. The LF/HF ratio, an index of sympathetic activity, increased significantly in group G after pneumoperitoneum, but did not vary in group WL. In addition, the incidence of ventricular or supraventricular arrhythmias and the severity of the arrhythmias as determined by Lown's classification were higher in group G than in group WL. These findings suggest that intraoperative changes in autonomic nervous activity, due to increased intra-abdominal pressure, were smaller in patients undergoing laparoscopic cholecystectomy using the abdominal wall-lifting method than in those undergoing laparoscopic cholecystectomy using pneumoperitoneum. The results also demonstrated that hemodynamic changes were smaller in patients undergoing the abdominal wall-lifting method than in those undergoing pneumoperitoneum. It was concluded that hemodynamics should be carefully monitored during pneumoperitoneum, and that the abdominal wall-lifting approach in laparoscopic cholecystectomy is a method worthy of consideration for elderly patients or those with cardiopulmonary complications.

    In conclusion, from our own experience of laparoscopic surgery in DRC, we strongly believe that there is no reason to develop inguinal laparoscopic repair in developing countries. Laparoscopic repairs are more expensive and more difficult to perform and to learn. The next step of abdominal wall repairs in the developing world should focus on teaching the surgeons to use either commercial or low-cost mosquito meshes in open repairs and assessing the results of these procedures in such challeng...

    Full Text Available The objectives of abdominal hernia repair are to restore the structural integrity of the abdominal wall. Current techniques include primary closure, staged repair and the use of prosthetic materials. Techniques for mini-abdominoplasty include the use of the transverse lower abdominal incision and the resection of excess skin. We report a case of epigastric hernia repair through a transverse lower abdominal incision with the resection of excess of skin. Our purpose is to evaluate the results of the procedure by incorporating these aspects into an epigastric hernia repair, we found out that the procedures are made safer and the results are improved. Proper indication and details of the technique are described.

    The paper reports a free-breathing black-blood CINE fast-spin echo (FSE) technique for measuring abdominal aortic wall motion. The free-breathing CINE FSE includes the following MR techniques: (1) variable-density sampling with fast iterative reconstruction; (2) inner-volume imaging; and (3) a blood-suppression preparation pulse. The proposed technique was evaluated in eight healthy subjects. The inner-volume imaging significantly reduced the intraluminal artifacts of respiratory motion (p  =  0.015). The quantitative measurements were a diameter of 16.3  ±  2.8 mm and wall distensibility of 2.0  ±  0.4 mm (12.5  ±  3.4%) and 0.7  ±  0.3 mm (4.1  ±  1.0%) for the anterior and posterior walls, respectively. The cyclic cross-sectional distensibility was 35  ±  15% greater in the systolic phase than in the diastolic phase. In conclusion, we developed a feasible CINE FSE method to measure the motion of the abdominal aortic wall, which will enable clinical scientists to study the elasticity of the abdominal aorta.

    The study was carried out on 10 swine of 20-30 kg body weight. Five animals were assigned to each of 2 groups. An aneurysm of the abdominal aorta was created experimentally in animals from the first and second study group. After 4 weeks, animals from the second group were subject to aneurysm repair using an aortic prosthesis. During the experiment, we measured the myoelectric activity of the muscular layer of the abdominal aorta and aneurysmal lesion with the ultrasonographic technique. Measurements of the aorta and aneurysmal lesion and histopathological analyses were carried out post-mortem. We found a statistically significant decrease in the myoelectric activity of the aorta on the aorta-straight prosthesis interface and a significant decrease in the thickness of the muscular layer of the aorta on the aorta-prosthesis interface. No similar changes were found for experimentally induced aneurysms of the abdominal aorta. A straight prosthesis graft may not be the perfect option in the treatment of abdominal aortic aneurysm, as it contributes to the remodelling of the tissue on the prosthesis-aorta interface. This may result in the relapse of an aneurysm and post-operative complications.

  16. Techniques for Abdominal Wall Closure after Damage Control Laparotomy: From Temporary Abdominal Closure to Early/Delayed Fascial Closure—A Review

    Directory of Open Access Journals (Sweden)

    2016-01-01

    Full Text Available Open abdomen (OA has been an effective treatment for abdominal catastrophes in traumatic and general surgery. However, management of patients with OA remains a formidable task for surgeons. The central goal of OA is closure of fascial defect as early as is clinically feasible without precipitating abdominal compartment syndrome. Historically, techniques such as packing, mesh, and vacuum-assisted closure have been developed to assist temporary abdominal closure, and techniques such as components separation, mesh-mediated traction, bridging fascial defect with permanent synthetic mesh, or biologic mesh have also been attempted to achieve early primary fascial closure, either alone or in combined use. The objective of this review is to present the challenges of these techniques for OA with a goal of early primary fascial closure, when the patient’s physiological condition allows.
