METHODS: We present a unique case of a 45-year-old man with his right middle finger embedded with rings. Limited finger flexion was noted because of flexor tendon injury caused by the dorsal migration of the embedded ring through joint. The rings were removed under anesthesia, resulting in the resolution of swelling and recover of osseous structure. Follow-up examinations revealed no residual edema or numbness, indicating preserved neurovascularization, despite the dorsal migration of the ring.
CONCLUSIONS: Our unique case reveals continuous finger ring migration without compromising neurovascular bundles, with review of 30 cases emphasizing the importance of psychiatric consultation. Timely intervention yielded nearly half of patients achieving full recovery.

BACKGROUND: Fish bone ingestion is commonly encountered in emergency department. It poses a diagnostic and therapeutic challenge particularly when it migrates extraluminally, necessitating a comprehensive and multidisciplinary approach for successful management.
METHODS: Here we reported four cases of extraluminal fish bone. The first patient was a 68-year-old Chinese man who had odynophagia shortly after a meal involving fish. The second was a 50-year-old Iban man who reported a sharp throat pain after consuming fish 1 day prior. The third patient was a 55-year-old Malay woman who developed throat pain and odynophagia after consuming fish 1 day earlier. The fourth patient, a 70 year-old Iban man, presented late with odynophagia, neck pain, swelling, and fever 1 week after fish bone ingestion. These unintentional fish bone ingestions faced challenges and required repeat computed tomography scans using multiplanar reconstruction in guiding the surgical removal of the fish bone.
CONCLUSIONS: We underscore the significance of multiplanar reconstruction in pinpointing the fish bone\'s location, demonstrating the migratory route, and devising an accurate surgical plan.

A woman in her 20s was referred to a tertiary hospital emergency department for management of a migrating Implanon NXT. The Implanon was inserted 1 week prior by the patient\'s general practitioner who was unable to palpate the Implanon after insertion and hence, ordered an ultrasound scan which showed an actively migrating Implanon in the left basilic vein. She had mild chest pain, and her physical examination, ECG and blood tests were unremarkable. A CT chest showed a 31 mm foreign body within the right lower lobar artery. The foreign body was removed by interventional radiology by accessing the right internal jugular vein under ultrasound guidance and inserting a 6 FR pig catheter into the pulmonary trunk. The position was confirmed with angiogram and the foreign body was removed using a goose neck snare. The patient was discharged the same day with no complications, and fell pregnant a few months afterwards.

This case report details a rare case of contraceptive implant migration in a young woman. The migration was discovered three years post-insertion during a routine replacement visit. Despite the absence of pulmonary symptoms, a CT scan revealed the implant in the inferior lobe of the right lung. The patient was referred for further evaluation, but immediate surgical removal was deferred. This case report highlights the importance of healthcare providers recognising migration as a rare complication during implantation and suggests self-examination as a potential preventive strategy.

Acute appendicitis is the most common surgical abdominal pathology worldwide that requires immediate intervention. We report a 78-year-old patient who presented with acute appendicitis. A computed tomography (CT) of the abdomen and pelvis showed acute appendicitis due to appendiceal orifice obstruction from a migrated biliary stent. The condition was successfully treated nonoperatively with endoscopic stent removal, allowing his discharge 72 hours after his admission.

BACKGROUND: The aim of this research was to analyse the current literature on displaced dental implants in the mandibular body, including local and systemic variables related to their cause, and to identify the most frequent location.
METHODS: The study conducted a search of three databases (Pubmed, Scopus, and Web of Science) using specific index terms such as \'dental implant\', \'displacement\', \'dislocation\', \'displaced\', and \'mandible\'. The analysis focused on the direction of displacement and the characteristics of the bone tissue (bone quality, density, and quantity) in cases where dental implants were displaced.
RESULTS: A total of 371 articles were obtained. Thirteen of these articles were selected and read in full. To define bone quality, the Lekholm and Zarb classification, modified by Rosas et al., was used. The type II-B bone, which is characterized by thick cortical bone surrounding cancellous bone with extremely wide medullary spaces, presented the largest number of complications. Twenty-two cases were found in which the displacement direction was horizontal. Of these, four were displaced vestibularly, fourteen lingually, and four remained in the center. Additionally, 24 cases presented vertical displacement, with 12 displaced towards the inferior border of the mandible, 9 towards the middle or adjacent to the inferior dental nerve canal, and 3 above the inferior dental nerve canal.
CONCLUSIONS: The accidental displacement of implants within the mandibular body is associated with various risk factors, including the characteristics of the bony trabeculum and the size of the medullary spaces. It is reasonable to suggest that only an adequate pre-surgical diagnostic evaluation, with the help of high-resolution tomographic images that allow a previous evaluation of these structures, will help to have better control over the other factors, thus minimizing the risk of displacement.

Ventriculoperitoneal shunt (VPS) is the most common procedure done for hydrocephalus in the paediatric population. While shunt infection and shunt malfunction remain the most common complications, shunt migration is not frequently observed. Being present in a large peritoneal cavity, theoretically, a shunt can travel to a variety of locations. Even among these, scrotal migration is quite uncommon. This case highlights the significance of keeping this possibility in mind while evaluating a case of shunt malfunction. It also discusses various nuances of surgically managing scrotal migration.

BACKGROUND: Conversion of SG to Roux-en-Y gastric bypass (RYGB) is increasing. Intrathoracic migration of the sleeve (ITM) often seems associated and is increasingly reported.
METHODS: Patients who underwent a conversion of SG to RYGB from August 2013 to December 2022 were included. Two groups were compared: patients operated on for weight loss failure (WLF gp) and those operated on for gastroesophageal reflux disease (GERD gp). Demographic data, the incidence of ITM, weight loss outcomes, resolution of symptoms, and morbidity were analyzed.
RESULTS: Fifty-nine patients were included with an average follow-up of 32 months: 46 patients in the GERD gp (78%) were compared to 13 patients (22%) in the WLF gp. Groups were comparable regarding age and gender, but BMI and commodities were significantly higher in the WLF gp. In the GERD gp, on preoperative gastroscopy, 30% had a esophagitis, 48% had an ITM which required a posterior crural closure versus no esophagitis (p=0.02) and 23% of ITM in the WLF gp (p=0.11). Conversion led to 93% of GERD symptom improvement. In the WLF gp, mean TWL% was 15.3%, significantly greater than in the GERD gp (TWL% = 4.6%, p = 0.01). The complication rate was 10% at 30 days and 3.4% after 30 days, not significantly different between groups.
CONCLUSIONS: The main indication of conversion of SG to RYGB was because of GERD: in these indications, the incidence of ITM was high requiring a surgical treatment with a very good efficacy on symptoms. Weight loss results were disappointing.
