Proximal migration of Plastibell circumcision: two case reports and review of the literature

Background Male circumcision is one of the oldest and most commonly performed surgical procedures in the world; in fact, one of every 3 males in the world is circumcised. Plastibell circumcision is the commonest procedure performed worldwide with higher rates of satisfaction and lower rates of complications. Case presentation We present two cases, 4 and 5 months old with proximal migration of Plastibell ring with penile incarcerations that were managed successfully. We aim to highlight the necessary precautions needed to avoid serious complications after a minor surgical procedure. Conclusions Plastibell circumcision is a minor surgical procedure that is underestimated with the potential for major and serious complications. The implementation of the law against the practice of non-professional individuals, standardization of the procedure, and improvement of communication are highly recommended to avoid unnecessary and serious complications. Plastibell ring circumcision still needs further studies to examine ring antimigration, re-designing, and the best types and sizes of threads used. Lastly, studies are also needed to determine a cost-effective routine follow-up visit post-Plastibell circumcision procedures.

Treatment of Complete Displacement of the Bilateral Legs into an Aortic Aneurysm Using an Iliac Branch Device

Purpose: Migration is a major cause of reintervention after endovascular aneurysm repair (EVAR). In patients with common iliac artery (CIA) dilation due to proximal migration of the iliac limb, internal iliac blood flow can be preserved by implanting an iliac branch device (IBD). Case Report: In this report, we discuss the case of a patient in whom the bilateral limbs were completely displaced into the aortic aneurysm due to proximal migration of the iliac limb after EVAR. By taking advantage of the characteristics of this migration, we formed a pull-through wire through the native terminal aorta without passing through the flow divider of the stent graft, and the IBD was deployed safely. Conclusion: The present case indicates that the preservation of at least 1 internal iliac artery is possible in patients with CIA dilation due to proximal migration of the iliac limb. However, the unique features of each case must be considered to determine the appropriate approach.

A Case Report: Is the Lack of Sufficient Radial Force Unfreezing the “Frozen Elephant Trunk”?

The “frozen elephant trunk” is a hybrid technique to treat aortic arch and proximal descending aortic pathologies in a single step. Despite its encouraging early and long-term results, some stent-graft-related adverse events have been reported. Here, we describe a possible treatment option to “re-freeze” the FET in case of loss of landing zone. We report a patient who developed significant kinking of the FET over the course of the first 2 postoperative years. The 1-year follow-up computed tomography angiography (CTA) showed significant kinking and proximal migration of the endograft portion of the FET, resulting in new thrombus formation. Due to kinking and thrombus progression in subsequent CTA follow-ups (2 years and 2½ years) with risk for peripheral embolization, a secondary endovascular repair was indicated. Transfemoral relining of the stent component with a thoracic aortic endovascular repair (Zenith®TX2®30142) stent-graft was performed. In the context of postoperative aneurysm sac shrinkage, the low radial force and lack of longitudinal stiffness of the hybrid graft may lead to proximal migration, thus secondary kinking, emphasizing the importance of an adequate degree of oversizing of the primary graft and an appropriate follow-up. Selection of a suitable graft for a particular pathology concerning the radial force and longitudinal stiffness is furthermore important.

Case series of retained rectal foreign body. A Malaysian experience.

Retained rectal foreign body, with its associated social stigma, is a medical condition that is infrequently reported in Malaysia. We report the surgical management of five cases of retained foreign objects in the rectum seen over a one-year period. There were three young and two elderly male patients. One of the elderly patients presented with altered bowel habits and an abdominal mass that mimicked a symptomatic colonic tumor. All patients had an abdominal radiograph which clinched the diagnosis of a retained foreign rectal body. Successfully retrieved objects included two bottles, one bidet device, and two sex toys. Open surgery for retrieval of the impacted rectal foreign body was required in one patient. All underwent successful retrievals without any adverse postoperative complications. In our case series, retained rectal foreign bodies were observed only in the male gender. The age presentation was bimodal, with age groups in the twenties and sixties. The treatment options used for the retrieval of these impacted foreign bodies included transanal extraction or explorative laparotomy. Proximal migration and delayed presentation are possible indications for the latter approach.

Proximal Migration of Pancreatic Duct Stent in Pancreas Divisum: Challenges in Retrieval and Review of the Literature

Pancreas divisum is the most common congenital malformation of the pancreas. Sometimes it is considered an etiology when patients present with recurrent episodes of pancreatitis. Endoscopic retrograde pancreatography (ERP) with selective cannulation of the minor papilla with sphincterotomy and stent placement are performed in these patients. Proximal migration of pancreatic stents in pancreas divisum is rare and challenging to manage. We describe a case of proximal migration of a pancreatic stent in a patient with pancreas divisum and perform a review of literature.

A Case Report of Proximal Migration of Fibular Head with Intact Peroneal Nerve in a Post-Operative Infected Tibia Gap Non-union Managed by Ilizarov Technique

Introduction: We hereby present a rare case of proximal fibular head migration associated with Ilizarov technique for infected tibia gap non-union due to follow-up failure in post-operative management during the coronavirus disease (COVID) pandemic. Case Report: A 45-year-old male patient had undergone primary external fixation with wound debridement for a compound tibia shaft fracture Grade 3 A Gustilo class which later on with a healed external wound with a discharging sinus at the fracture site was confirmed to be infected non-union and subsequently managed by Ilizarov ring fixation over an antibiotic coated intramedullary nail and local gentamycin beads after a necrotic bone fragment of around 6 cm was excised. Post-operative protocol of compression and distraction was initiated and the patient educated regarding the same before discharge. As the world over was hit by the COVID pandemic and the lockdown limited all possible movements in our country, the patient could not follow up for monitoring the Ilizarov limb lengthening procedure. He presented to us after 4 months after the relaxation of lockdown with radiological union at the docking site but with a shortening of about 3 cm. Vigorous knee range physiotherapy failed to improve range beyond 90° which prompted us to check X-ray the knee joint and revealed the complication of proximal fibular head migration of 4 cm but with no neurodeficit and currently the patient is being managed with full weight mobilization with the help of crutch and shoe raise and an improved knee range till 100° of flexion with no pain tenderness or any other complaints. Conclusion: Having knowledge of this possible rare complication and the need for follow-up and monitoring with the importance of patient education makes practicing orthopedic surgeons equipped to handle and anticipate such undesirable complications.

Evaluation of a new cemented highly cross-linked all-polyethylene cup: a prospective and randomised study assessing wear and fixation characteristics using radiostereometric analysis

Background and purpose: The aim of this prospective, randomised and controlled study was to evaluate the wear and fixation properties of a new cemented highly cross-linked all-polyethylene (HXLPE) cup in comparison with a conventional cemented ultra-high molecular weight polyethylene (ConvPE) cup using radiostereometric analysis (RSA). Patients and methods: A total of 58 patients (58 hips) with primary osteoarthritis (OA) were enrolled in a randomised controlled trial to receive either a ConvPE cup (control) or HXLPE cup (intervention) with identical geometry. The subjects were randomised in a 1:1 ratio. The primary endpoint was proximal wear measured as femoral head penetration into the cup, secondary outcomes were 3D-wear and annual proximal wear from 1 to 5 years. Cup fixation was measured as movement of the cup in relation to the acetabular bone with proximal migration being the primary outcome measure, 3D-migration and change in inclination as secondary outcomes. The patients were followed for 5 years with RSA performed postoperatively, at 3, 12, 24, and 60 months. Results: The HXLPE displayed a lower median proximal femoral head penetration compared to ConvPE, with a median difference at 2 years of –0.07 mm (95% CI, –0.10 to –0.04 mm), and –0.19 mm (95% CI, –0.27 to –0.15 mm) at 5 years. Annual proximal wear between 1 and 5 years was 0.03 mm/year for HXLPE and 0.06 mm/year for ConvPE (mean difference 0.05 mm, [95% CI, 0.03–0.07 mm]). Proximal migration, 3D migration and change in inclination was numerically slightly higher for HXLPE, albeit not statistically significant. Conclusions: Compared to ConvPE, the HXLPE cup displayed significantly lower polyethylene wear. Cup migration was not statistically significant different. ClinicalTrials.gov Identifier: NCT04322799.
