buttonhole

The creation of a scleral flap during trabeculectomy can be complicated by a buttonhole, partial amputation at the limbus, and extensive thinning. In some cases, the procedure must be aborted to prevent more serious postoperative complications. This report describes a technique of converting complicated trabeculectomy into ab externo cyclodialysis. A 41-year-old patient with congenital glaucoma presented with a perforated scleral wall with the choroidal tissue exposed during the dissection of the partial-thickness scleral flap...

BACKGROUND: Tympanoplasty is the most common operation performed by an Otolaryngologist worldwide.Type 1 tympanoplasty involves repair of pars tensa of tympanic membrane, when the middle ear is normal. The most widely used method is underlay technique using temporalis facia. In buttonhole tympanoplasty, the temporalis fascia is anchored to the handle of malleus through the buttonhole. OBJECTIVE: To compare and analyze graft uptake and hearing outcome in button hole technique and underlay technique...

Safe and effective arteriovenous fistula (AVF) puncture is very important to reduce the wound complications of haemodialysis (HD). For AVF puncture in dialysis patients, there is a lack of clarity and consistency regarding the relative advantage of buttonhole (BH) over rope-ladder (RL) cannulae in terms of wound complications. The study was published in several scientific databases including Cochrane Library, PubMed and Embase by October 2023. Data from all controlled trials looking at the effect of BH and RL on wound complications in haemodialysis patients were included...

INTRODUCTION: This report highlights a rare case of complex metacarpophalangeal (MCP) joint dislocation, commonly referred to as Kaplan's lesion. This type of dislocation typically results from a hyperextension injury and requires surgical intervention as closed maneuvers are unsuccessful in reducing the dislocation. Surgical reduction for complex MCP joint dislocations is commonly done through classic volar or dorsal approaches. This report presents a case of a complex MCP joint dislocation and the surgical approach taken to address the issue...

BACKGROUND: Cirsoid aneurysm of the scalp is a rare arteriovenous fistula having a traumatic, congenital, iatrogenic, or idiopathic etiology. Its presentation can range from a small swelling to a large pulsatile mass with tinnitus, headache, and scalp necrosis. OBSERVATIONS: A 67-year-old female presented with a gradually increasing swelling on her forehead and head since childhood and no history of trauma. Examination revealed 12 × 5 cm tortuous midline swelling...

BACKGROUND: Since in Italy there are no official data on vascular access (VA) for hemodialysis the Vascular Access Project Group (VAPG) of the Italian Society of Nephrology (SIN) designed a national survey. METHODS: A 35-question survey was designed and sent it to the Italian facilities through the SIN website. The basic questions were the prevalence, the location, and the surveillance of VA, the bedside use of ultrasound, the use of fluoroscopy for central venous catheter (CVC) placement, and of buttonhole technique, the role of nephrologist in the access creation...

BACKGROUND: Radical prostatectomy by lateral approach allows performing a prostatectomy through a buttonhole, with direct access to the seminal vesicle and fully sparing the anterior pubovesical complex. Our aim is to show the results of reproducing the technique of robotic radical prostatectomy by lateral approach, in terms of intraoperative, postoperative, oncological and functional parameters. METHODS: We analyzed 513 patients submitted to robotic radical prostatectomy by lateral approach from January 2015 to March 2021, operated on by two surgeons in our institution...

BACKGROUND AND OBJECTIVES: Descemet's stripping endothelial keratoplasty (DSEK) has emerged as the preferred method for posterior lamellar keratoplasty, as it enables the replacement of the compromised host endothelium with a viable donor lamella. The objective of this study was to assess the impact of DSEK on surgical outcomes and visual acuity. METHODS: The research was carried out from November 2019 to October 2021, encompassing a sample of 18 patients (18 eyes) who satisfied the inclusion criteria for DSEK...

BACKGROUND AND HYPOTHESIS: Buttonhole cannulation of native arteriovenous fistulas (AVFs) appears associated with an increased infectious risk. We previously reported a dramatic increase in the incidence of infectious events after shift to buttonhole in an in-center hemodialysis unit, largely reduced after staff (re)education regarding strict respect of the procedure. We assessed the evolution over the following 12-years period in our center. METHODS: In this prospective follow-up of a previous, pre (rope-ladder)-post (buttonhole) comparison (2001-2010), all in-center hemodialysis patients with a native AVF were included from July 1st, 2010 to December 31st, 2022...

Adequate cannulation technique (CT) methods and successful puncture are essential for hemodialysis (HD) and arteriovenous fistula (AVF) maintenance. This systematic review and meta-analysis was designed to identify which CT allows better AVF primary patency and lower rates of complications in HD patients. The search was carried out on the CINAHL, MEDLINE, Cochrane Library, and Joanna Briggs Institute Library databases to identify all randomized controlled trials (RCTs) and observational studies comparing clinical outcomes of buttonhole (BH) versus rope ladder cannulation (RL) from 2010 to 2022...

BACKGROUND: French guidelines for the prevention of vascular access infections in a haemodialysis setting were released in 2005. Compliance with these guidelines is currently unknown. Our aim was to assess compliance with guidelines for vascular access infection prevention in French haemodialysis units, and to describe the difficulties reported. METHODS: A cross-sectional survey was conducted between March and December 2019 in 200 haemodialysis units randomly selected in France...

BACKGROUND: Injury of the rectum with intact anal sphincter is an extremely rare but very serious complication of vaginal delivery. It is also called a "buttonhole" tear. CASE: We present two cases of "buttonhole" tear/injury. RESULTS: In one case, the injury was recognized at the time of delivery and adequately treated. In the other case the injury was not diagnosed on time and the patient was treated for complications on the 6th postpartal day...

Genital tract trauma and obstetric anal sphincter injuries are known complications of normal vaginal and assisted vaginal delivery. Cervical tears are an uncommon complication that can lead to significant postpartum haemorrhage and may have implications for future pregnancies. Careful evaluation of the genital tract, including the cervix, along with adequate resuscitation are essential to reduce maternal morbidity and mortality. This is a case report of a 36-year-old primigravida woman at 41 + 6 weeks of gestation with delay in the second stage requiring Neville Barnes forceps delivery...

INTRODUCTION: Elbow dislocations are commonly encountered by orthopedic surgeons all over. Management is straightforward and the result is generally satisfactory. However, in a small subset, associated injuries like convergent or divergent dislocations at superior radioulnar joints are present. These associated injuries are often missed initially leading to their delayed treatment and suboptimal elbow function. We report one such rare case of Convergent dislocation at the elbow. Although reported from other parts of the world till date, there has been none reported from India...

BACKGROUND: Staphylococcus lugdunensis (S lugdunensis) is a species of coagulase-negative Staphylococcus and a constituent of human skin flora. S lugdunensis has gained notoriety for its virulence, which resembles Staphylococcus aureus (S aureus) . S lugdunensis is now recognized as an important nosocomial pathogen and cause of prosthetic device infections, including vascular catheter infections. CASE PRESENTATION: A 60-year-old man with a history of uncontrolled type 2 diabetes mellitus and end-stage renal disease on home hemodialysis via arteriovenous fistula (AVF) presented to the emergency department for evaluation of subacute progressive low back pain...

CASE REPORT: Traumatic hip dislocations require prompt diagnosis and reduction to preserve the native joint. The classic irreducible posterior hip fracture-dislocation has been described as an immobile, slightly flexed, and internally rotated hip on physical exam. Classically, this irreducible pattern is associated with an ipsilateral femoral head fracture. The purpose of our report is to present an irreducible posterior hip dislocation with preserved motion in the setting of an unstable pelvic ring injury without associated femoral head pathology...

BACKGROUND: Choosing between flaps or grafts to substitute the urethral plate in 2-stage hypospadias repair has been a matter of debate with no consensus in the literature. Flaps have reliable blood supply that maybe theoretically less liable for strictures or contractures. Grafts are more versatile, which can be used in primary and recurrent cases when healthy local skin is deficient.In this report, our aim was to compare outcomes of grafts and flaps when used to substitute the urethral plate in two-stage repair of primary proximal hypospadias with ventral curvature...

Purpose: To report sterile corneal necrosis as a severe and rare complication after Bowman Layer Transplantation (BTL). Methods: A 35-year-old woman with Down syndrome and advanced progressive keratoconus in her left eye was scheduled for a BLT. The patient rubbed her eyes and did not tolerate contact lenses. Following standard technique, a 8mm Bowman layer graft was placed into a intrastromal pocket with no intraoperative complications. Results: Postoperatively, the patient remained stable and topography showed notable central flattening but 17 days after the BTL was performed she developed a sterile corneal necrosis...

An obstetric rectal buttonhole tear (ORBT) is a rare obstetric complication with only 21 cases reported in the literature. The choice of two- or three-layer repair of ORBT is controversial. In this case, the author describes (with high-quality images) an ORBT repaired in three layers in order to provide clinical lessons to healthcare professionals involved in obstetrical care. The patient was a 26-year-old pregnant woman with a previous vertex delivery and 4 previous first-trimester miscarriages. In the index pregnancy, she had a spontaneous vertex vaginal birth of a 3095 g male baby at 39 weeks of gestation...

INTRODUCTION: In most cases, the volar plate interposition renders the complex metacarpophalangeal joint dislocation, commonly known as Kaplan's lesion, intractable, necessitating open reduction. The capsuloligamentous attachments around the joint and the head of the metacarpal are buttonholed in this dislocation, limiting closed reduction. CASE REPORT: It is presented here a case of 42-year-old male with the left Kaplan's lesion with open wound. The dorsal technique would have decreased neurovascular compromise and prevented the reduction otherwise by exposing the fibrocartilagenous volar plate directly; however, in this case, the volar route was adopted since an open wound exposed the metacarpal head volarly rather than dorsally...
