Total Nasal Reconstruction for Extruded, Pending Extrusion and Severely Displaced Silicone Nasal Implants in Asian Patients

The Australian population is 10% of Asian origin, and many of our Asian patients have had nasal augmentation using prosthetic material prior to immigration or as medical tourists back in their country of origin. Insertion of nasal prostheses is the most common way to augment the nasal dorsum in the Asian patient and although there is a trend towards autogenous primary augmentation still, the vast majority of patients seen in clinical practice have had augmentation by the insertion of foreign material generally silicone.

Successful adjustment for self-expanding metallic stent migration using a flexible bronchoscope with two biopsy forceps technique

Although tracheobronchial stents are widely used for tracheal obstruction due to malignant or benign stenosis, stent migration has been reported as a major postoperative complication. A self-expandable metallic stent (SEMS) is more easily introduced compared with silicone stents. However, it is also difficult to remove or replace without complications. We report a new technique for successful SEMS adjustment using a flexible bronchoscope with two biopsy forceps.

Uveitis-Glaucoma-hyphema Syndrome

After 20 years of catarct surgery, a 66 years old man has found to have subluxtaed intraocular lens with satbilizing haptic protuding through the pupil.

Levonorgestrel-Releasing Intrauterine Contraceptive Device in the Peritoneal Cavity: A Report of Two Cases

BACKGROUND

In modern gynecology an intrauterine device (IUD) with levonorgestrel is often used as a method of contraception. The levonorgestrel-releasing intrauterine system is small and T-shaped. In Slovenia, only a gynecologist may insert it. CASES: We present 2 clinical cases in which, despite strong evidence that no perforation had occurred during insertion, the IUD was found outside the uterus. If the IUD threads are not visible or the IUD cannot be located in the uterine cavity, an X-ray of the abdomen must be performed. If the IUD is found in the abdominal cavity outside the uterus, removal by laparoscopy is carried out.

CONCLUSION

Given the large number of inserted IUDs, the complications associated with the levonorgestrel-releasing intrauterine system are quite rare, and therefore it remains one of the most widely used contraceptive methods.

Combination Surgery With Transcorneal Microincision Vitrectomy Surgery and Intrascleral Intraocular Lens Fixation for Spontaneous Intraocular Lens Luxation

To present a combination technique for two cases of in-the-bag intraocular lens (IOL) luxation into the vitreous cavity. Vitrectomy was performed via a cornea microincision vitrectomy system, and the luxated IOL was fixed into the sclera. IOL fixation is simple from no trocar cannulas and less disrupted conjunctiva. Postoperative corneal endothelial cell density in Case 1 and Case 2 were reduced by -2.1% and -5.1%, respectively. Postoperative frequency of hexagon was decreased in Case 1 but maintained in Case 2. The authors concluded that combination surgery has distinct benefits for IOL luxation; however, long-term corneal changes need to be further assessed.

Diagnosis and treatment of massive porcupine quill migration in a dog

A 5-year-old spayed female Boston terrier mixed breed dog was presented with porcupine quill migration. The quills were difficult to detect directly using computed tomography and magnetic resonance imaging. This case highlights difficulties faced in detecting porcupine quills with current diagnostic imaging modalities and describes surgical and medical management of a patient with massive quill migration.

Image-guided Percutaneous Transhepatic Removal of Fish Bone from Liver Abscess

We present a case of a woman who was diagnosed with a hepatic abscess secondary to a migrated fish bone. As the patient did not improve after percutaneous drainage of the abscess, image-guided percutaneous transhepatic removal of the fish bone was performed. Fish bones in hepatic abscesses are typically removed surgically, with the fish bone left in situ in a number of cases. There has been only another reported case of percutaneous transhepatic fish bone removal. We conclude that in the rare case of a hepatic abscess complicating fish bone migration, image-guided percutaneous transhepatic removal of the offending foreign body is a feasible alternative to surgery, especially in high surgical risk patients.

Removal of a broken trigen intertan intertrochanteric antegrade nail

Implant breakage is a serious complication after cephalomedullary nailing for unstable intertrochanteric fracture. Failure usually occurs at the lag screw hole in the nail body. On the other hand, lag screw failure is extremely rare and occurs around the nail-lag screw junction. We experienced rare mechanical failure of the Intertan nail, which showed breakage at the lag screw hole and failure of the integrated compression screw underneath the main lag screw.

Prominent metalware from pelvic surgery causing dyspareunia

We present a case of female dyspareunia secondary to metalware placement during extensive pelvic surgery following a motor vehicle accident. The patient initially had an uneventful recovery from her operations. However, she noticed pain with vaginal intercourse, due to a screw tip which was palpable on vaginal examination. X-ray imaging confirmed long screws in the medial part of an anterior column plate, which were impacting on the anterior vaginal wall. Subsequent percutaneous removal of two screws resulted in resolution of her symptoms of painful vaginal intercourse. While the pain from mechanical irritation of the vagina was resolved, the patient continues to have difficulty with intercourse, which is related to hip pain as a result of her initial injury and complex pelvic surgery.

Injizierte dermale Füllermaterialien – ein spezieller Befund der Mundhöhlenschleimhaut

Injizierbare dermale Füllermaterialien werden in der plastischen Chirurgie heute beim Auftreten der ersten Falten auch schon bei jüngeren Menschen als Mittel der Wahl angeboten. Viele organische Substanzen wie Rinderkollagen (resorbierbar), Hyaluronsäure (resorbierbar) oderanorganische Substanzen wie Silikon (nichtresorbierbar) werden dazu eingesetzt.

A rare case of perforation of the subhepatic appendix by a toothpick in a patient with intestinal malrotation: laparoscopic approach

Foreign body ingestion is not an uncommon problem in clinical practice. While most ingested foreign bodies pass uneventfully through the gastrointestinal tract, sharp foreign bodies such as toothpicks should cause intestinal perforation. We reported the case of a perforation of the appendix caused by a toothpick, which also pierced the liver without hepatic damages, in a male with an intestinal malrotation and subhepatic appendix. The patient was admitted to our hospital for abdominal pain in the right upper quadrant. An abdominal computed tomography scan revealed the anomalous position of the first portion of the large intestine with inflamed appendix. A laparoscopic appendicectomy and the exploration of the abdominal cavity was performed using minimally invasive technique.

Thoracic spinal epidural abscess caused by fishbone perforation: A case report and review of literature

RATIONALE

Ingestion of a fishbone is a common cause of esophageal injury, but spinal epidural abscess (SEA) is a rare condition due to the esophageal penetration by a swallowed fishbone. Prompt diagnosis can be seldom made owing to incomplete patient history taking and difficulties in imaging evidence identification.

PATIENT CONCERNS

We describe the case of a 62-year-old woman who was stuck in her throat by a fishbone, and complained of back pain, paresis of the lower limbs and fever, successively. To our knowledge, this is the first case report that we know of thoracic SEA caused by fishbone perforation.

DIAGNOSES

About 20 days after the onset of severe back pain, she was diagnosed with SEA based on the clinical presentation and imaging findings.

INTERVENTIONS

Antibiotic therapy and rehabilitation therapy were carried out afterwards. However, due to exacerbation of her condition, surgical intervention had to be taken eventually.

OUTCOMES

It is quite unfortunate for this patient to have a poor prognosis due to a delayed diagnosis and an improper management.

LESSONS

A number of lessons can be learnt from this case.

Dislodgement and gastrointestinal tract penetration of bone cement used for spinal reconstruction after lumbosacral vertebral tumor excision: A case report

INTRODUCTION

Polymethylmethacrylate (PMMA) cement is useful for spinal reconstruction, but can cause complications including new vertebral fractures, neurological disorders and pulmonary embolism. We report a case in PMMA cement used for spinal reconstruction after tumor curettage dislodged and penetrated the gastrointestinal tract.

DIAGNOSES

The patient was diagnosed with a retroperitoneal extragonadal germ cell tumor at age 27 years. After chemotherapy and tumor resection, the tumor remained. It gradually increased in size and infiltrated lumbosacral vertebrae, causing him to present at age 35 years with increased low back pain. Image findings showed bone destruction in the vertebral bodies accompanied by neoplastic lesions. The left and right common iliac arteries and inferior vena cava were enclosed in the tumor on the anterior side of the vertebral bodies. Lumbosacral bone tumor due to direct extragonadal germ cell tumor infiltration was diagnosed. A 2-step operation was planned; first, fixation of the posterior side of the vertebral bodies, followed by tumor resection using an anterior transperitoneal approach, and spinal reconstruction using PMMA cement. After surgery, the PMMA cement gradually dislodged towards the anterior side and, 2 years 9 months after surgery, it had penetrated the retroperitoneum. The patient subsequently developed nausea and abdominal pain and was readmitted to hospital. The diagnosis was intestinal blockage with dislodged PMMA cement, and an operation was performed to remove the cement present in the small intestine. There was strong intra-abdominal adhesion, the peritoneum between the vertebral bodies and intestine could not be identified, and no additional treatment for vertebral body defects could be performed. After surgery, gastrointestinal symptoms resolved.

CONCLUSION

Although this was a rare case, when using bone cement for vertebral body reconstruction, the way of anchoring for the cement must be thoroughly planned to assure no cement dislodgement can occur.

Outcomes of Endovascular AAA Repair in Patients with Hostile Neck Anatomy Using Adjunctive Balloon-Expandable Stents

Hostile neck anatomy remains the predominant reason that patients are denied endovascular aneurysm repair (EVAR). We reviewed our experience of EVAR with use of prophylactic adjunctive proximal balloon-expandable stents in patients with hostile neck anatomy and adjunctive proximal balloon-expandable stents in patients with type I endoleaks. Of 140 patients who underwent EVAR between 2000 and 2004, we reviewed data for 19 patients in whom we used proximal balloon-expandable stents. By high-resolution computed tomography scan or angiography, hostile neck anatomy was classified as length <15 mm, neck diameters = 26 mm, circumferential thrombus at the proximal neck, angulated neck =60 degrees, and neck bulge or reverse taper necks. Patients were considered to have hostile anatomy if they met 1 or more of the above-cited criteria. All patients underwent AAA repair with commercially available endograft systems, Zenith (Cook, Bloomington, IN) and AneuRx (Medtronic/AVE, Minneapolis, MN). Balloon-expandable stents utilized included Cordis-Palmaz stents (17/19) and eV3 Max stents (2/19). Stents were deployed in the proximal graft with transrenal extension. AneuRx (18/19) and Zenith (1/19) endografts were used in all of the patients. Of the 19 patients, 15 had prophylactic stent placement for known hostile neck anatomy and 4 patients had stent placement for type I endoleak. Assisted primary technical success was achieved in all patients. Three patients had maldeployment of the endograft or proximal stent requiring additional endovascular interventions at the time of surgery. No endografts were deployed too low requiring stent placement. Procedure-related complications occurred in 2 of 19 patients. These included 1 operative death secondary to pneumonia and 1 patient who developed progressive renal failure. Short-term clinical success was achieved in 17 of 19 patients. Two patients required secondary interventions, 1 due to device migration with secondary conversion to open repair, and an endoleak, which, on angiogram, was a large type II endoleak successfully treated with coiling of the inferior mesenteric artery. One patient was observed to have a type II endoleak with no associated aneurysm enlargement. Short-term results suggest the use of prophylactic adjunctive balloon-expandable stents may decrease the incidence of secondary interventions related to hostile neck anatomy when used as an adjunctive measure with EVAR. Based on our experience, we feel EVAR may be offered to an expanded patient population with hostile neck anatomy with use of prophylactic balloon-expandable stents.

Wandering Bullet Embolizing to the Pulmonary Artery: A Case Report

Whilst a missile embolizing to the right side of the heart is a common occurrence, embolization to the pulmonary arteries is rare. We report a case of a bullet entering through the right internal jugular vein to the right ventricle, and then migrating to the left pulmonary artery, and its management. To our knowledge, this is the first reported such case from the Indian subcontinent.

Corneal toxicity after Ozurdex(®) migration into anterior chamber

OBJECTIVE

To describe a case of corneal toxicity after migration of a dexamethasone implant into the anterior chamber.

CASE REPORT

A 62-year-old man with aphakia and a history of vitrectomy received a dexamethasone implant for a refractory Irvine-Gass syndrome. Thirty days later, the implant migrated into the anterior chamber causing endothelial contact with secondary corneal oedema that justified the removal of the implant without resolution of the oedema.

DISCUSSION

Clinical tolerability to dislocated implant is poor in cases with pre-existing corneal oedema, and because of this, it must be removed early. In cases of aphakia and vitrectomy, the increased risk of Ozurdex(®) dislocation justifies performing a prior endothelial count.

Death Due to Intra-aortic Migration of Kirschner Wire From the Clavicle: A Case Report and Review of the Literature

Migration of orthopedic fixation wires into the ascending aorta though a rare occurrence can have devastating consequences. Therefore, prompt recognition, with immediate and cautious retrieval of the implant is paramount in averting these complications.We present a case of a 5-year-old boy with the intra-aortic migration of a K-wire used for the treatment of a right clavicle fracture. He was transferred to us with a history of syncope, chest pain, and shortness of breath 7 days after K-wire placement, which was performed at another hospital. On CT scan, the wire was found to be partially inside the ascending aorta, which was associated with massive hemopericardium and cardiac tamponade. The patient was taken up for emergency surgery for the removal K-wire and for the management of cardiac temponade. However, the patient developed cardiac arrest during the induction of intravenous anesthesia and endotracheal intubation. The K-wire was retrieved from the thorax via thoracotomy. However, the patient died 10 days after the surgery.As the migration of wires and pins during orthopedic surgery can cause potentially fatal complications, these should be used very cautiously, especially for percutaneous treatment of shoulder girdle fractures. The patients with such implants should be followed frequently, both clinically and radiographically. If migration occurs, the patient should be closely monitored for emergent complications and the K-wire should be extracted immediately.

Thoracic Nerve Root Entrapment by Intrathecal Catheter Coiling: Case Report and Review of the Literature

BACKGROUND

Intrathecal catheter placement has long-term therapeutic benefits in the management of chronic, intractable pain. Despite the diverse clinical applicability and rising prevalence of implantable drug delivery systems in pain medicine, the spectrum of complications associated with intrathecal catheterization remains largely understudied and underreported in the literature.

OBJECTIVE

To report a case of thoracic nerve root entrapment resulting from intrathecal catheter migration.

STUDY DESIGN

Case report.

SETTING

Inpatient hospital service.

RESULTS/ CASE REPORT

A 60-year-old man status post implanted intrathecal (IT) catheter for intractable low back pain secondary to failed back surgery syndrome returned to the operating room for removal of IT pump trial catheter after experiencing relapse of preoperative pain and pump occlusion. Initial attempt at ambulatory removal of the catheter was aborted after the patient reported acute onset of lower extremity radiculopathic pain during the extraction. Noncontrast computed tomography (CT) subsequently revealed that the catheter had ascended and coiled around the T10 nerve root. The patient was taken back to the operating room for removal of the catheter under fluoroscopic guidance, with possible laminectomy for direct visualization. Removal was ultimately achieved with slow continuous tension, with complete resolution of the patient's new radicular symptoms.

LIMITATIONS

This report describes a single case report.

CONCLUSION

This case demonstrates that any existing loops in the intrathecal catheter during initial implantation should be immediately re-addressed, as they can precipitate nerve root entrapment and irritation. Reduction of the loop or extrication of the catheter should be attempted under continuous fluoroscopic guidance to prevent further neurosurgical morbidity.

Endoscopic management of internally migrated pancreatic duct stents (with video)

BACKGROUND AND AIMS

Spontaneous intestinal migration of pancreatic stents is a known phenomenon. However, retrieval of a proximally migrated pancreatic stent (PMPS) poses a therapeutic challenge. The primary aim of this study was to evaluate technical success of endoscopic retrograde of cholangiopancreatography (ERCP) for extraction of PMPS, including number of sessions, need of surgery for failures and intervention-induced adverse events. The secondary outcome was to evaluate long-term effects of PMPS on the ductal morphology.

METHODS

Data of patients undergoing pancreatic stenting since January 2007 was reviewed. Fourteen patients were found to have PMPS. The level of stent migration was divided into two categories: level 1: retropapillary migration of the stent, the distal end seen till the genu (n = 6). Level II: PMPS with distal end seen beyond genu (n = 8). The stents were placed due to following reasons, prophylactic pancreatic stenting after common bile duct stone extraction (n = 6), pancreatic endotherapy for chronic pancreatitis (n = 7), and recurrent acute pancreatitis with incomplete pancreas divisum (n = 1). ERCP was done using Olympus TJF 160/180 duodenoscope. Stent extraction was initially attempted using rat tooth forceps, snare with or without wire, wire-guided basket, and in case of failures, pancreatoscope was used (Boston Scientific, USA).

RESULTS

PMPS could successfully be retrieved in 13 out of 14 patients (92.8 %). Stents were retrieved using stone extraction balloon in two (14.2 %), modified angiography balloon in one (7 %), rat tooth in three patients (21.4 %), over-the-wire snare in three patients (21.4 %), lasso technique in one (7 %), and under pancreatoscope guidance in three patients (21.4 %). Adverse events encountered were mild pancreatitis (n = 2, 14 %) and self-limited bleeding (n = 2, 14 %).

CONCLUSIONS

Endotherapy of PMPS could be complex and associated with adverse events. Level II-migrated stents may require specialized methods like pancreatoscopy for stent retrieval.
