    INTRODUCTION AND HYPOTHESIS: This retrospective study reports the 1-year outcome in women who underwent mesh-augmented Prolift surgery performed from 2006 to 2008. There were a total of 254 patients, with 128, 106 and 20 patients receiving total, anterior and posterior Prolift, respectively.

    METHODS: Incidence of thigh pain was lower in 2008 compared to 2006 and 2007 (p < 0.0001). The percentage of patients requiring blood transfusions (p = 0.09), duration of IDC ≥ 7 days (p = 0.27), wound dehiscence and re-operation rate were lower in 2008 in contrast to 2006 and 2007 (p = 0.43). Only 209 patients (82.3%) were available for review at 1 year. There were two (1.0%) cases of recurrent vault prolapse.

    RESULTS: The subjective and objective cure rates at 1 year after this mesh implant surgery in 2006, 2007 and 2008 were 92.1% and 92.1%; 97.0% and 92.4% and 100% and 97%, respectively. The mesh erosion rate was remarkably lower in 2008 as compared to 2007 and 2006 (p < 0.001).

    CONCLUSIONS: This synthetic mesh-augmented implant surgery is effective and safe, and surgical outcome appears related to the learning curve of the surgeon.

    AIM: The aim of this study was to evaluate the management outcomes of advanced pelvic organ prolapse (POP) in nulliparous women.

    METHODS: Eight nulliparous women diagnosed with POP ≥ stage 3 between January 2005 and August 2013, according to the Pelvic Organ Quantification System (POPQ), were reviewed. Seven were managed surgically and one was managed with pessary. Primary outcome was surgical objective cure (POP-Q ≤ 1) and subjective cure, defined as negative response to questions 2 and 3 on Pelvic Organ Prolapse Distress Inventory 6. Secondary outcomes were complications, symptoms' severity and quality of life according to validated questionnaires.

    RESULTS: A total of 1275 prolapse patients with POP-Q ≥ stage 3 were managed surgically, among whom seven (0.55%) were nulliparous. Each woman had at least one risk factor associated with POP. Risk factors identified were history of pelvic trauma, obesity, menopause, chronic cough, hard physical labor and constipation. Five patients underwent surgical correction (vaginal hysterectomy with sacrospinous fixation) with mesh (Perigee, n = 3; Avaulta, n = 2). Two patients had uterine preservation without mesh (hysteropexy with sacrospinous ligament fixation). One patient preferred treatment with pessary. The total cure rate (objective and subjective cure rates) was 86% after surgical reconstructive surgery.

    CONCLUSION: Management of nulliparous advanced POP poses significant challenges with regard to uterine preservation, future pregnancy and childbirth. Conservative management with pessary insertion should be offered followed by surgical correction. Reconstructive surgery with mesh may improve prolapse symptoms objectively and subjectively.

    OBJECTIVE: To evaluate the outcome of transvaginal mesh surgery as a management of recurrent pelvic organ prolapse, in patients previously treated with sacrocolpopexy.

    CASE REPORT: A series of three patients who developed recurrent pelvic organ prolapse more than 9 years after sacrocolpopexy. A 50-year-old and two 77-year-old patients who presented with recurrent pelvic organ prolapse at 9, 15 and 17 years, respectively after the primary abdominal sacrocolpopexy were managed by transvaginal mesh surgery.

    CONCLUSION: Management of recurrent pelvic organ prolapse using transvaginal mesh would be an option for patients treated previously by sacrocolpopexy.

    Removal of the whole sternum for malignant tumours results in a large defect, causing severe deformity and possible paradoxical movements of the chest wall. The reconstruction of the resultant large defect of the chest wall is often complex and difficult. Commonly used materials include rib autograft, steel strus acrylic plate and various synthetic meshes such as Goretex or Marlex mesh, with a myocutaneous flap for coverage. A case of a 48-year-old man with sternal chondrosarcoma successfully treated with thoracoplasty using acrylic plate-marlex mesh combination following near total resection of sternum is reported.

    Our aim is to study the inflammatory response towards the collagen-coated and non-coated polypropylene meshes in rats and the urodynamic investigation post-operatively. Forty-two female Sprague Dawley were divided into 7 groups of 6 rats; Control, Day 7 and 30 for Sham, Avaulta Plus (MPC), Perigee (MP). UDS were taken at days 7 and 30. Mesh with the vagina and bladder wall was removed and sent for immunohistochemical examination. Results showed intense inflammatory reaction on day 7 in the study groups which decreased on day 30. IL-1, TNF-α, MMP-2 and CD31 were observed to decrease from day 7 to day 30. NGF was almost normal on day 30 in all groups. UDS showed no difference in voiding pressure. Both Study and Sham groups had shorter voiding interval (VI) on day 7 but significantly lower in MPC. VI had significantly increased on day 30 in all groups. Voided volume was significantly lower in the mesh groups even when an increase was seen on day 30. In conclusion, the higher levels of IL-1, TNF-α and MMP-2 in collagen-coated polypropylene mesh imply greater inflammation than the non-coated polypropylene mesh. Mesh implantation can lead to shorter voiding interval and smaller bladder capacity.

    PURPOSE: Laparoscopic hernioplasty has become a popular choice for inguinal hernia repair since its advent in 1990s. Postoperative pain is an undesirable clinical outcome impairing daily activity of 22.5% of patients. The aim of this study is to evaluate postoperative acute and chronic pain via inflammatory markers as an objective assessment following tacks or glue mesh fixation in TEP repair.

    METHODS: Sixty-six (66) patients with unilateral uncomplicated inguinal hernia were randomized into 34 patients in the tacker and 32 patients in cyanoacrylate glue mesh fixation in TEP repair. The extent of surgical trauma was evaluated by measuring inflammatory markers of C-reactive protein, white blood cell count at 48 h, and ESR at 3 months postoperatively. Postoperative acute and chronic pain was assessed by recording the visual analogue scale scores and surgical complications were recorded over 3 months of the study period.

    RESULTS: The median CRP and WBC levels at postoperative 48 h in both groups raised significantly from the baseline values (p  0.05). The median ESR level increased significantly at 3 months postoperatively from baseline in the glue mesh fixation group only (p  0.05). There was no significant difference for VAS scores at all timelines between the tacker and glue mesh fixation group (p > 0.05).

    CONCLUSION: Cyanoacrylate glue mesh fixation technique as an alternative method to mechanical fixation in TEP repair is comparable to tacker and can be considered to be safe and feasible.

    Paraesophageal hernia with intrathoracic mesentericoaxial type of gastric volvulus is a rare clinical entity. The rotation occurs because of the idiopathic relaxation of the gastric ligaments and ascent of the stomach adjacent to the oesophagus through the hiatus defect, while the gastroesophageal junction remains in the abdomen. The open approach remains the gold standard therapy for most patients. Here we report the case of a patient with such a condition who underwent a successful laparoscopic surgery. A literature search revealed that this is the first case report from Southeast Asia.

    Ferrocement panels, while offering various benefits, do not cover instances of low and moderated velocity impact. To address this problem and to enhance the impact strength against low-velocity impact, a fibrous ferrocement panel is proposed and investigated. This study aims to assess the flexural and low-velocity impact response of simply supported ferrocement panels reinforced with expanded wire mesh (EWM) and steel fibers. The experimental program covered 12 different ferrocement panel prototypes and was tested against a three-point flexural load and falling mass impact test. The ferrocement panel system comprises mortar reinforced with 1% and 2% dosage of steel fibers and an EWM arranged in 1, 2, and 3 layers. For mortar preparation, a water-cement (w/c) ratio of 0.4 was maintained and all panels were cured in water for 28 days. The primary endpoints of the investigation are first crack and ultimate load capacity, deflection corresponding to first crack and ultimate load, ductility index, flexural strength, crack width at ultimate load, a number of impacts needed to induce crack commencement and failure, ductility ratio, and failure mode. The finding revealed that the three-layers of EWM inclusion and steel fibers resulted in an additional impact resistance improvement at cracking and failure stages of ferrocement panels. With superior ultimate load capacity, flexural strength, crack resistance, impact resistance, and ductile response, as witnessed in the experiment program, ferrocement panel can be a positive choice for many construction applications subjected to repeated low-velocity impacts.

    Obturator hernia is rare, but it must be considered in elderly patients who present with small
    bowel obstruction. The diagnosis is challenging unless there is a high index of suspicion as
    the presenting symptoms and signs are usually non-specific. Presence of positive HowshipRomberg sign is considered pathognomonic. Early diagnosis and rapid surgical intervention
    will reduce the high morbidity and mortality associated with undiagnosed obturator hernia. We
    report a case of a 93-year-old female patient who was admitted to our surgical department with
    symptoms of intestinal obstruction of 3-days duration. Howship-Romberg sign was negative.
    Computed tomography (CT) demonstrated the presence of left obturator hernia with proximal
    small bowel obstruction and no sign of strangulation. The patient had emergency laparotomy
    post-CT where the incarcerated bowel loop was released and the obstructed bowel was
    decompressed without any complication. The hernial defect was close with a mesh and the
    patient had an uneventful recovery post-surgery. In this case, we highlight that diagnosis of
    obturator hernia must always be considered in elderly patients who present with intestinal
    obstruction. Urgent CT could establish a rapid pre-operative diagnosis and aids in appropriate
    surgical intervention planning which is crucial in optimising the outcome.

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

    OBJECTIVE: To compare the clinical efficacy, recurrence, complications and quality of life changes 3 years after Elevate-A/single incision mesh surgery anterior apical (SIM A) and sacrospinous ligament fixation (SSF) in the management of pelvic organ prolapse (POP).

    MATERIALS AND METHODS: A prospective cohort study, 139 women, underwent transvaginal surgery for anterior and/or apical POP > stage 2, 69 patients had SIM A and 70 patients had SSF. The objective cure was defined as POP ≤ stage 1 anterior, apical according to POP-Q. Subjective cure is patient's negative feedback to question 2 and 3 of pelvic organ prolapse distress inventory 6 (POPDI-6). Patient's satisfaction was reported using validated quality of life questionnaires. Multi-channel urodynamic study was used to report any voiding problems related to the prolapse surgery 6 months after surgery.

    RESULTS: 119 patients completed a minimum of 3 years follow-up. 89.8% is the overall prolapse correction success rate for SIM A and 73.3% for SSF group (p = 0.020), and 96.6% versus 73.4% at the anterior vaginal compartment respectively (p ≤ 0.001). Statistically significant difference was noticed in apical compartment with 98.3% with SIM A and 85.0% with SSF (p = 0.009). The subjective success rate, 86.4% in the SIM A and 70.0% in the SSF arm (p = 0.030) was significantly noted. Only, Pelvic Organ Prolapse Distress Inventory-6 (POPDI-6) showed significant improvement. Operation time and intra-operative blood loss tend to be more with SIM A.

    CONCLUSION: SIM A has better 3 years objective and subjective cure rate than SSF in the anterior and/or apical compartment prolapse.

    Complications in the form of esophageal injury, tracheal injury, injury to carotids, implant failure, loosening of screws, etc do occur after anterior cervical surgeries. Although intra-operative esophageal injuries are as such rare, there have been few reports of delayed esophageal perforation as well after anterior cervical surgeries. We report a very rare case of migration of missing screw from anterior cervical plate after anterior cervical corpectomy and plating, which had ultimately migrated down to colon and had to be removed via colonoscopy. Along with removal of migrated screw from colon, revision of failed anterior cervical surgery was done wherein plate and screws were removed with mesh cage left in-situ as it was snug-fit while pharyngeophageal perforation was explored and was found to be spontaneously healing, with addition of posterior Bohlman's interspinous wiring for added stability. Migration of screw from the anterior cervical plate into the colon although very rare, should be always kept in mind and its potentially serious complications. We also conclude that particular attention should be given to elderly people with poor bony quality who have high chances of implant failure, along with attention to proper cage size, screw position and proper locking of the screw to further lessen the chances of implant failure.

    This investigation aims at the reclamation of Cr(VI) from synthetic electroplating industrial effluent by electroextraction process namely electrochemical ion exchange (EIX). An electrochemical ion exchange reactor of desired dimensions was fabricated with the help of ion-permeable membranes, stainless steel cathode and PbO₂ coated Ti expanded mesh anode. The performance of the reactor was studied in batch recirculation mode, continuous flow mode at different experimental conditions. The influence of various experimental factors, for instance, initial metal ion concentration (20, 300, 1000 mg/L of Cr(VI)), applied voltages (2.5 V, 5 V, 7.5 V, 10 V) and flow rates of the process stream (2, 4, 6, 8, 10, 12 and 14 ml/min) on removal/reclamation efficiency was deliberated. For comparison purposes, an electrodialysis process was conducted at the same optimal conditions. It was found that the EIX process with three compartments has more removal efficiency at optimum experimental conditions than the electrodialysis process. The continuous flow process of the reactor with 300 mg/L of Cr(VI) as inlet concentration has studied to predict the breakeven point of the reactor. It was noted that Cr(VI) ion concentration in the treated wastewater is almost zero up to the discharge of 20 liters of treated rinse water.

    BACKGROUND: With many different operative techniques in use to reduce the incidence of incisional hernias (IH) following a midline laparotomy, there is no consensus among the clinicians on the efficacy and safety of any particular repair technique. This meta-analysis compares the prophylactic onlay mesh repair (POMR) and primary suture repair (PSR) for the incidence of IH.

    METHODS: A meta-analysis and systematic review of MEDLINE, PubMed Central (via PubMed), Embase (via Ovid), SCOPUS, ScienceDirect, Google Scholar, SCI and Cochrane Library databases were undertaken. Seven randomized controlled trials assessing the outcomes of PSR and POMR were analyzed in accordance with the PRISMA statement. The risk of bias was assessed using the Rob2 tool.

    RESULTS: According to the pooled analysis, POMR significantly reduced the incidence of IH compared to the PSR (OR 5.82 [95% CI 2.69, 12.58] P

    Conventionally, panel boards are produced with material flex or microparticle with P.U. or U.F. as adhesives. However, in this study, nanoparticle with epoxy resin as an adhesive was used to produce nanoboard. Coconut shell nanoparticle composite with epoxy resin as an adhesive was prepared using a compression molding technique. The coconut shell particles were originally 200 mesh size and then milled mechanically with a ball mill for the duration of 10, 20, 30, and 40 h (milling times) to produce nanoparticles. The composition ratio of the composite is 85 vol.% of coconut shell and 15 vol.% of epoxy resin. The formation of nanoparticles was observed with transmission electron microscopy (TEM). The mechanical, physical, and microstructure properties of the composite were examined with X-ray diffraction, scanning electron microscopy, atomic force microscopy, and universal testing machine. The results established that the properties of the composite (microstructures, mechanical, and physical) are influenced by the duration of milling of coconut shell particles. The modulus and flexural strength of the composite improved with an increase in the milling time. The density, thickness swelling, and porosity of the composite were also influenced by the milling times. The result suggested that the composite properties were influenced by the particle size of the coconut shell. The coconut shell nanoparticle composite can be used in the manufacturing of hybrid panels and board.
