Abstract	Benign afferent loop obstruction (ALO) is a complication that occurs after general surgery making Roux-en-Y or Billroth-II reconstruction and has typically been treated surgically. However, the surgery is difficult to conduct in about 25% of cases due to comorbidity and nonoperative management has been attempted. Here, we report two cases of benign ALO that were treated with percutaneous transhepatic afferent loop balloon dilatation and indwelling catheter, including one case with no improvement after surgery.

Abstract	Background: Acute ileal diverticulitis is a rare disease mimicking acute appendicitis. Inaccurate diagnosis with a low prevalence and nonspecific symptoms leads to delayed or improper management. Methods: This retrospective study aimed to investigate the characteristic sonographic (US) and computed tomography (CT) findings with clinical features in seventeen patients with acute ileal diverticulitis diagnosed between March 2002 and August 2017. Results: The most common symptom was abdominal pain (82.3%, 14/17) localized to the right lower quadrant (RLQ) in 14 patients. The characteristic CT findings of acute ileal diverticulitis were ileal wall thickening (100%, 17/17), identification of inflamed diverticulum at the mesenteric side (94.1%, 16/17), and surrounding mesenteric fat infiltration (100%, 17/17). The typical US findings were outpouching diverticular sac connecting to the ileum (100%, 17/17), peridiverticular inflamed fat (100%, 17/17), ileal wall thickening with preserved layering pattern (94.1%, 16/17), and increased color flow to the diverticulum and surrounding inflamed fat on color Doppler imaging (100%, 17/17). The perforation group had a significantly longer hospital stay than non-perforation group (

Abstract	Background: Extracorporeal membrane oxygenation (ECMO) is an intervention for severe heart and lung failure; however, it poses the risk of complications, including gastrointestinal bleeding (GIB). Comprehensive analyses of GIB in patients undergoing ECMO are limited, and its impact on clinical outcomes remains unclear. Methods: This retrospective study included 484 patients who received venovenous and venoarterial ECMO between January 2015 and December 2022. Data collected included patient characteristics, laboratory results, GIB details, and interventions. Statistical analyses were performed to identify risk factors and assess the outcomes. Results: GIB occurred in 44 of 484 patients (9.1%) who received ECMO. Multivariable analysis revealed that older age (odds ratio [OR], 1.04; 95% confidence interval [CI], 1.01-1.06; p=0.0130) and need to change the ECMO mode (OR, 3.74; 95% CI, 1.75-7.96; p=0.0006) were significant risk factors for GIB, whereas no association was found with antiplatelet or systemic anticoagulation therapies during ECMO management. Half of the patients with GIB (22/44, 50%) underwent intervention, with endoscopy as the primary modality (19/22, 86.4%). Patients who underwent ECMO and developed GIB had higher rates of mortality (40/44 [90.9%] vs. 262/440 [59.5%]) and ECMO weaning failure (38/44 [86.4%] vs. 208/440 [47.3%]). Conclusion: GIB in patients undergoing ECMO is associated with adverse outcomes, including increased risks of mortality and weaning failure. Even in seemingly uncomplicated cases, it is crucial to avoid underestimating the significance of GIB.

Abstract	Purpose: This study aimed to compare the complication rates of non-absorbable suture (NAS) and n-butyl-2-cyanoacrylate (NBCA) skin adhesive for skin closure during totally implantable venous access devices (TIVADs) implantation. Methods: Between March 2020 and February 2021, 586 consecutive patients who underwent TIVAD implantation were retrospectively analyzed. Two groups of patients suture with NAS ( Results: Nineteen cases of complications occurred (0.294/1000 catheter-days) in the NAS group and 17 cases (0.210/1000 catheter-days) in the NBCA group. The difference in the complication rates between the two groups was not statistically significant ( Conclusion: In TIVADs implantation, skin closure using NBCA showed no difference in the occurrence of infectious complications compared with conventional non-absorbable skin suture.

Abstract	Background: Oblique lumbar interbody fusion (OLIF) is a surgical technique for lumbar interbody fusion that allows surgeons to use a large cage while preserving the spine muscles. The surgical corridor of OLIF is close to the ureter in the retroperitoneal space and therefore entails a potential for injury to this organ. Although there are some published cases of ureteral injury that were identified during OLIF, to our knowledge, there have been no reports about delayed ureteral strictures and kidney atrophy after OLIF. We report a case of ureter stricture and ipsilateral kidney atrophy that was incidentally identified a few months postoperatively without signs of ureter injury during the operation. Case description: A 49-year-old woman presented with low back and right leg pain. On lumbar magnetic resonance imaging, a Meyerding grade 1 spondylolisthesis of L4 on L5 with L4 nerve root encroachment was confirmed. The patient underwent L4/L5 OLIF and was discharged on the 10th day after surgery with improved symptoms. Three months later, an abdominopelvic computed tomography performed for an unrelated condition showed left kidney atrophy. A retrograde ureteropyelogram confirmed a stricture near the operation site. A ureter stent was successfully inserted to overcome the stricture, but renal atrophy was not reversed. Conclusions: Ureter injury may be observed with several months' delay after OLIF in patients without symptoms or laboratory abnormalities, even if no direct injury was noted during the procedure.

Abstract	Purpose: To evaluate the effect of a motion artifact correction algorithm (MACA) on cone-beam computed tomography (CT) during transarterial chemoembolization for hepatic malignancies. Materials and methods: From June 2020 to March 2021, 42 patients with mild-to-severe motion artifacts detected using single cone-beam CT scans were evaluated retrospectively. The image quality of native and motion-corrected data was compared. The maximum intensity, sharpness, and full width at half maximum (FWHM) of 5 segmental hepatic arteries were quantitatively measured. The overall quality of maximum intensity projection (MIP) images, conspicuity of tumor-supplying arteries, and need for selective angiography to ascertain the vascular anatomy were qualitatively evaluated by multiple readers. Paired t and Wilcoxon signed rank tests were used to compare the parameters. Results: The mean maximum intensity and sharpness increased from 2,792.01 HU ± 451.36 to 3,148.40 HU ± 594.46 and from 0.31 ± 0.02/mm to 0.34 ± 0.02/mm, respectively, using the MACA (both P < .001). The MACA decreased the mean FWHM from 2.02 mm ± 0.27 to 1.78 mm ± 0.26 (P < .001). The overall quality of the MIP images and the conspicuity of the tumor-supplying artery were enhanced from 2.5 to 3.0 points and from 3.0 to 4.0 points, respectively (both P < .001). Selective angiography was expected to be omitted in 7 cases (16.7%, 7/42) after using the MACA. Conclusions: The MACA significantly improved both quantitative and qualitative image quality of cone-beam CT in selected patients with motion artifacts during transarterial chemoembolization for hepatic malignancies.

Abstract	The relationship between cancer and venous thromboembolism (VTE) has long been described. The risk of VTE in Asian patients with breast cancer remains largely unknown. This study described the incidence and risk factors of VTE in Korean patients with breast cancer. Data were collected from a retrospective database of patients who underwent breast cancer surgery between 2011 and 2020 at a single institution. The Cox proportional-hazards model was used to identify factors associated with VTE occurrences. Among the 2246 patients with breast cancer, 48 (2.1%) developed VTE during a median follow-up period of 53 months. The average incidence of VTE was 459 per 100,000 person-years. Age ≥ 60 years, male sex, chronic kidney disease, reconstructive procedures, and stage II or higher were independent predictive factors for VTE. VTE was associated with poor disease-free survival (hazard ratio (HR), 6.140; 95% confidence interval (CI), 3.480-10.835), and overall survival (HR, 8.842; 95% CI 4.386-17.824). Most VTE events were manageable with anticoagulation; three (6.3%) patients died of VTE, despite intensive care. The incidence of VTE was significantly elevated in Korean patients with breast cancer. Since VTE has a negative effect on oncologic outcomes of breast cancer, clinicians should manage its risk throughout their lifetime.
