Background/Aims: This study aimed to evaluate the performance of the Model for End-Stage Liver Disease (MELD) 3.0 for predicting mortality and liver-related complications compared with the Child-Pugh classification, albumin-bilirubin (ALBI) grade, the MELD, and the MELD sodium (MELDNa) score. Methods: We evaluated a multicenter retrospective cohort of incorporated patients with cirrhosis between 2013 and 2019. We conducted comparisons of the area under the receiver operating characteristic curve (AUROC) of the MELD3.0 and other models for predicting 3-month mortality. Additionally, we assessed the risk of cirrhosis-related complications according to the MELD3.0 score. Results: A total of 3,314 patients were included. The mean age was 55.9±11.3 years, and 70.2% of the patients were male. Within the initial 3 months, 220 patients (6.6%) died, and the MELD3.0had the best predictive performance among the tested models, with an AUROC of 0.851, outperforming the Child-Pugh classification, ALBI grade, MELD, and MELDNa. A high MELD3.0score was associated with an increased risk of mortality. Compared with that of the group with a MELD3.0 score <10 points, the adjusted hazard ratio of the group with a score of 10–20 pointswas 2.176, and that for the group with a score of ≥20 points was 4.892. Each 1-point increase inthe MELD3.0 score increased the risk of cirrhosis-related complications by 1.033-fold. The risk of hepatorenal syndrome showed the highest increase, with an adjusted hazard ratio of 1.149, followed by hepatic encephalopathy and ascites. Conclusions The MELD3.0 demonstrated robust prognostic performance in predicting mortality in patients with cirrhosis. Moreover, the MELD3.0 score was linked to cirrhosis-related complications, particularly those involving kidney function, such as hepatorenal syndrome and ascites.

Injury of the sagittal band, a crucial component of the extensor hood, can occur in various situations, including spontaneous events, trauma, and rheumatic diseases. This case presents a rupture of the sagittal band resulting from chronic irritation caused by a metacarpal head osteoma. A 22-year-old female presented with ulnar subluxation of the extensor tendon at the left third metacarpophalangeal joint, without any history of trauma or pain. Ultrasonography and computed tomography revealed a 1.7 mm-sized bony lesion on the radial side of the metacarpal head, accompanied by a partial tear of the radial sagittal band. Our hypothesis that chronic irritation of the sagittal band by the adjacent bony lesion led to the partial tear was confirmed by intraoperative findings. The lesion was excised, and the radial sagittal band was reconstructed. Histopathological examination confirmed a diagnosis of osteoma. To our knowledge, this is the first reported case of sagittal band rupture caused by an osteoma of the metacarpal head. This case underscores the importance of considering an underlying metacarpal head osteoma in patients with non-rheumatoid joints presenting, in the absence of a traumatic history, with a sagittal band rupture due to chronic irritation.

Full-thickness nail bed defects with exposure of the distal phalanx are difficult to reconstruct with limited options for bone coverage. A subcutaneous flap can effectively cover bone exposure, followed by a nail bed graft. We report a case of successful nail bed reconstruction using this approach, incorporating a split-thickness nail bed graft. A 59-year-old woman sustained injuries to the nail bed of the right middle finger from a blender blade. The defect, measuring 1.2 × 0.6 cm, was located in the center of the nail bed with associated bone exposure. Both lateral nail folds remained intact and our aim was to reconstruct the defect without disrupting these structures. A subcutaneous flap incorporating the digital artery was elevated. The flap was then transposed beneath the lateral nail fold and uninjured nail bed to provide coverage for the defect. This technique allowed for the reconstruction of the damaged area while preserving the vascular supply and ensuring adequate soft-tissue coverage. Three weeks post-surgery, the flap survived, and the eponychial folds were all preserved, allowing for a subsequent split-thickness nail bed graft. At 12 months post-surgery, the outcome was evaluated as “very good” according to Zook’s criteria.

Background: s/Aims: Systematic investigations into the prognostic impact of the longitudinal tumor location in gallbladder cancer (GBC) remain insufficient. To address the limitations of our pilot study, we conducted a multicenter investigation to clarify the impact of the longitudinal tumor location on the oncological outcomes of GBC. Methods: A retrospective multicenter study was conducted on 372 patients undergoing radical resections for GBC from January 2010 to December 2019 across seven hospitals that belong to the Daejeon–Chungcheong branch of the Korean Association of Hepato-Biliary-Pancreatic Surgery. Patients were divided into GBC in the fundus/body (FB-GBC) and GBC in the neck/cystic duct (NC-GBC) groups, based on the longitudinal tumor location. Results: Of 372 patients, 282 had FB-GBC, while 90 had NC-GBC. NC-GBC was associated with more frequent elevation of preoperative carbohydrate antigen (CA) 19-9 levels, requirement for more extensive surgery, more advanced histologic grade and tumor stages, more frequent lymphovascular and perineural invasion, lower R0 resection rates, higher recurrence rates, and worse 5-year overall and disease-free survival rates. Propensity score matching analysis confirmed these findings, showing lower R0 resection rates, higher recurrence rates, and worse survival rates in the NC-GBC group. Multivariate analysis identified elevated preoperative CA 19-9 levels, lymph node metastasis, and non-R0 resection as independent prognostic factors, but not longitudinal tumor location. Conclusions NC-GBC exhibits more frequent elevation of preoperative CA 19-9 levels, more advanced histologic grade and tumor stages, lower R0 resection rates, and poorer overall and disease-free survival rates, compared to FB-GBC. However, the longitudinal tumor location was not analyzed as an independent prognostic factor.

Anterior interosseous nerve syndrome (AINS) is typically characterized by dysfunction of the pure motor branch of the median nerve, primarily affecting the flexor pollicis longus and the flexor digitorum profundus (FDP) of the index finger, and occasionally involving the FDP of the middle finger and the pronator quadratus. Although various etiologies such as compressive neuropathy and isolated neuritis have been proposed, the most recent review describes AINS as a form of neuralgic amyotrophy. Its treatment remains a matter of debate; the most frequently discussed approach is conservative treatment followed by surgical intervention above the medial epicondyle level if recovery is not achieved. In the case described herein, a hematoma resulting from blunt trauma at the forearm level compressed the anterior interosseous nerve (AIN), with clinical features and diagnostic findings very similar to those of typical AINS. Early surgical removal of the hematoma led to complete recovery without complications. Despite the current understanding of AINS pathophysiology and treatment, this case emphasizes the need to consider the possibility of AIN palsy due to forearm lesions. We report on the clinical course and successful treatment of this case to highlight this important consideration.

Purpose: This study presents the outcomes of a modified loop-locking suture technique for repairing complete flexor digitorum profundus (FDP) tendon divisions at the terminal level. Traditional methods, such as pullout sutures or tendon fixation, are commonly used; however, this paper explores the reliability of the loop-locking suture technique. Methods: From June 2011 to January 2024, the modified loop-locking suture technique was performed in 21 cases of FDP tendon division in which the distal stump was less than 1 cm in length. Core and epitendinous sutures were made using polydioxanone 4-0 and poliglecaprone 25 4-0. The study focused on 13 patients aged 24 to 68 years, with an average tendon stump length of 0.61 cm. Ten cases necessitated microsurgical repair involving both arterial and nerve repair. A dorsal protective splint was used for an average of 5 weeks. The outcomes measured included active and passive range of motion, grip strength, and key and pulp pinch. Results: The mean follow-up period was 12 months. No re-ruptures occurred, although two cases required tenolysis. The average active range of motion at the distal interphalangeal joint was 61.5°. Grip strength and pulp pinch averaged 95.3% and 86.8%, respectively, compared to the contralateral side. Flexion contracture was observed in three cases, with no quadriga effect. Conclusion The modified loop-locking suture technique provides sufficient functional recovery for FDP tendon divisions in Zone 1a and distal Zone 1b, even with a short tendon stump.
