Materials and methods: The Duncan, HU, SMC, Pretzel, Nicky's and square knots were selected for comparisons with UM knot. All knots were prepared with size 2 HiFi® suture by a single experienced surgeon and tested with cyclic loading and load to failure tests. The ease of learning was assessed objectively by recording the time to learn the first correct knot and the total number of knots completed in 5 min by surgeons and trainees.
Results: The UM knot average failure load is significantly superior to the HU knot (p
METHOD: This case series report includes all 19 consecutive cases presenting to the Chang Gung Craniofacial Center for combined orthognathic surgery with Asian double eyelid suture method blepharoplasty. The double eyelid crease height was measured as the vertical line between the upper eyelid margin (eyelid lash) and the upper eyelid crease, observed at the mid-pupillary line with the eyes in primary gaze.
RESULTS: There were no complications or relapse reported within this time period. There was significant improvement in the left and right mid-pupillary double eyelid crease height postsurgery. There were no statistically significant differences between the left and right mid-pupillary double eyelid crease heights after surgery indicating good eyelid crease height symmetry bilaterally was obtained.
CONCLUSIONS: Orthognathic surgery combined with suture method blepharoplasty can be safely performed in the same surgical setting without inappropriate rise in costs or operating room time. This case series demonstrates that excellent esthetic results can be obtained in simultaneous bimaxillary orthognathic surgery with suture method Asian blepharoplasty.
OBJECTIVES: To assess the effectiveness of fibrin glue compared to sutures in conjunctival autografting for the surgical treatment of pterygium.
SEARCH METHODS: We searched CENTRAL (which contains the Cochrane Eyes and Vision Trials Register) (2016, Issue 9), Ovid MEDLINE, Ovid MEDLINE In-Process and Other Non-Indexed Citations, Ovid MEDLINE Daily, Ovid OLDMEDLINE (January 1946 to October 2016), Embase (January 1980 to October 2016), the ISRCTN registry (www.isrctn.com/editAdvancedSearch), ClinicalTrials.gov (www.clinicaltrials.gov), and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en). We did not use any date or language restrictions in the electronic searches for trials. We last searched the electronic databases on 14 October 2016.
SELECTION CRITERIA: We included randomised controlled trials (RCTs) in any setting where fibrin glue was compared with sutures to treat people with pterygium.
DATA COLLECTION AND ANALYSIS: Two review authors independently screened the search results, assessed trial quality, and extracted data using standard methodological procedures expected by Cochrane. Our primary outcome was recurrence of pterygium defined as any re-growth of tissue from the area of excision across the limbus onto the cornea. The secondary outcomes were surgical time and complication rate. We graded the certainty of the evidence using GRADE.
MAIN RESULTS: We included 14 RCTs conducted in Brazil, China, Egypt, India, Malaysia, New Zealand, Philippines, Saudi Arabia, Sweden and Turkey. The trials were published between 2004 and 2016, and were assessed as a mixture of unclear and low risk of bias with three studies at high risk of attrition bias. Only adults were enrolled in these studies.Using fibrin glue for the conjunctival autograft may result in less recurrence of pterygium compared with using sutures (risk ratio (RR) 0.47, 95% CI 0.27 to 0.82, 762 eyes, 12 RCTs; low-certainty evidence). If pterygium recurs after approximately 10 in every 100 surgeries with sutures, then using fibrin glue may result in approximately 5 fewer cases of recurrence in every 100 surgeries (95% CI 2 fewer to 7 fewer cases). Using fibrin glue may lead to more complications compared with sutures (RR 1.92; 95% CI 1.22 to 3.02, 11 RCTs, 673 eyes, low-certainty evidence). The most common complications reported were: graft dehiscence, graft retraction and granuloma. On average using fibrin glue may mean that surgery is quicker compared with suturing (mean difference (MD) -17.01 minutes 95% CI -20.56 to -13.46), 9 RCTs, 614 eyes, low-certainty evidence).
AUTHORS' CONCLUSIONS: The meta-analyses, conducted on people with pterygium in a hospital or outpatient setting, show fibrin glue may result in less recurrence and may take less time than sutures for fixing the conjunctival graft in place during pterygium surgery. There was low-certainty evidence to suggest a higher proportion of complications in the fibrin glue group.
PRESENTATION OF CASE: A 30-year-old woman, who had a previous cesarean delivery, opted for another cesarean section (CS) during this pregnancy. She claimed that her tummy was lax after her first experience of CS even with regular exercise. A standard CS procedure was carried out along with the new modified undermined suture technique for rectus muscle re-approximation. Post-operatively, the pain score was 2/10 without any evidence of hematoma, seromas or infection and the patient ambulates well. The patient did not complain of any pain or complications upon follow up after 2 weeks and 2 months post-operation. She claims that her abdomen is firmer, flatter and more stable compared to her previous operation experience.
DISCUSSION: This newly modified method prevents any defect or weakness on the anterior abdominal wall even if the rectus muscles fail to oppose itself during the healing process. It also mimics the function of the linea alba and avoid interrupting the contraction or injuring the muscle in order to avoid pain. Adhesion of the anterior uterine wall and the rectus sheath can be prevented by closure of the rectus muscle and burying the suture material within the muscle.
CONCLUSION: The newly modified undermined suture rectus muscle technique at cesarean delivery has the potential to improved patient's post-operative satisfaction.
METHODS: Patients undergoing elective midline laparotomy through standardized incisions in two tertiary hospitals from February 2017 to September 2018 were randomized to either LS or SS. The primary outcome was post-operative patient-controlled analgesia morphine usage at 24 h. Secondary outcomes were presence of surgical site infection and length of hospital stay (LOHS). Categorical variables were analysed using chi-squared analysis. Outcomes of study were tested for normal distribution. Skewed data were analysed using Mann-Whitney U-test.
RESULTS: Eighty-six patients were recruited (42 SS and 44 LS). The median age was 66 (interquartile range (IQR) 15). Majority were males (62.8%) and Chinese (50%). The median incision length was 17 cm in both groups. The median patient-controlled analgesia morphine usage 24 h post-operatively did not differ significantly (SS 21 mg, IQR 28.3; LS 18.5 mg, IQR 33.8, P = 0.829). The median pain score at rest (SS 1, IQR 1; LS 1, IQR 2, P = 0.426) and movement (SS 3, IQR 1; LS 3, IQR 2, P = 0.307) did not differ significantly. LOHS was shorter in the SS group (SS 6, IQR 4; LS 8, IQR 5, P = 0.034). The rate of surgical site infection trended lower in the SS group with no statistical difference.
CONCLUSION: There were no differences in post-operative pain between SS and LS but we found that there were shorter LOHS in SS arm as secondary outcome.
MATERIAL AND METHODS: Randomized controlled trials evaluating the effects of these 2 treatment modalities were searched from PubMed and other electronic databases between January 1991 and July 2018. The outcome variables analyzed included operating time, complications, recurrence of HH or wrap migration, reoperation, hospital stay and quality of life.
RESULTS: Five randomized controlled trials totaling 478 patients (suture=222, mesh=256) were analyzed. For reoperation variable, the odds ratio was significantly 3.26 times higher for the suture group. For recurrence of HH, the odds ratio for the suture group was nonsignificantly 1.65 times higher compared with the mesh group. Comparable effects were noted for all other variables.
CONCLUSIONS: Mesh repair seems to be superior to suture cruroplasty for large HH repair. Therefore, the routine use of mesh may be advantageous in selected cases.
METHODS: The model exploits the principle of dynamic and geometric similarity, so while dimensions were up to 30× greater than actual, the flow had similar properties. Scleral flaps were represented by transparent 0.8- and 1.6-mm-thick silicone sheets on an acrylic plate. Dyed 98% glycerin, representing the aqueous humor was pumped between the sheet and plate, and the equilibrium pressure measured with a pressure transducer. Image analysis based on the principle of dye dilution was performed using MATLAB software.
RESULTS: The pressure drop across the flap was larger with thinner flaps, due to reduced rigidity and resistance. Doubling the surface area of flaps and reducing the number of sutures from 5 to 3 or 2 also resulted in larger pressure drops. Flow direction was affected mainly by suture number and position, it was less toward the sutures and more toward the nearest free edge of the flap. Posterior flow of aqueous humor was promoted by placing sutures along the sides while leaving the posterior edge free.
CONCLUSION: We demonstrate a new physical model which shows how changes in scleral flap thickness and shape, and suture number and position affect pressure and flow in a trabeculectomy.
