Globally, the elderly population is increasing rapidly, which means that the number of deformity correction operations for elderly spine deformity patient has increased. On the other hand, for aged patients with deformity correction operation, preoperative considerations to reduce the complications and predict a good clinical outcome are not completely understood. First, medical comorbidity needs to be evaluated preoperatively with the Cumulative Illness Rating Scale for Geriatrics or the Charlson Comorbidity Index scores. Medical comorbidities are associated with the postoperative complication rate. Managing these comorbidities preoperatively decreases the complications after a spine deformity correction operation. Second, bone densitometry need to be checked for osteoporosis. Many surgical techniques have been introduced to prevent the complications associated with posterior instrumentation for osteoporosis patients. The preoperative use of an osteogenesis inducing agent

Purpose:
This study aimed to investigate the overall operational status of medical school admission interview evaluations in South Korea and explore the operational experience of universities conducting interview evaluations.
Methods:
This study used a mixed-methods approach, combining quantitative and qualitative methods. Through a nationwide survey and data collection from 39 medical schools, the quantitative analysis explored interview evaluations procedures, the purpose of the interview evaluations, and the competencies expected of medical school freshmen. Concurrently, qualitative data were obtained through focus group discussions with 12 professors from 10 medical schools, providing in-depth insights into the operational experiences and challenges faced during interview evaluations.
Results:
In the quantitative data, interview evaluations were most prevalent in the “comprehensive school records screening” for rolling admissions (85.5%), but less common in regular admissions (18.6%). Private schools (64.2%) showed a statistically significant higher proportion of interview admissions than public schools (11.1%) in the “high school grades focused admission” (p<0.01). Metropolitan areas (50.0%) conducted interview evaluations more frequently than non-metropolitan areas (11.1%) in the “College Scholastic Ability Test-focused admissions” (p<0.05). In the qualitative data, professors recognize the dominant role of “negative selection” in filtering out unsuitable candidates. Challenges in maintaining a consistent evaluator pool and team-based question development were acknowledged. Strategies, such as seeking student feedback for question improvement and conducting study meetings for interviewer preparation are essential.
Conclusion
This study illuminates the operation of admissions interview evaluations in South Korea, revealing variations across regions and admissions types. These findings offer insights for enhancing medical school admission processes, guiding future research and policy.

Purpose:
It is known that as the T stage of a carcinoma progresses, the prognosis becomes poorer. However, there are few studies about factors that affect the prognosis of T4 advanced colon cancer. This study aimed to identify the prognostic factors associated with disease-free survival (DFS) and overall survival (OS) in T4 colon cancer.
Methods:
Patients diagnosed with stage T4 on histopathology after undergoing curative surgery for colon cancer between March 2009 and March 2018 were retrospectively analyzed for factors related to postoperative survival. Primary outcomes were DFS and OS.
Results:
Eighty-two patients were included in the study. DFS and OS of the pathologic (p) T4b group were not inferior to that of the pT4a group. Multivariate analysis showed that differentiation (hazard ratio [HR], 4.994; P = 0.005), and laparoscopic surgery (HR, 0.323; P = 0.008) were significant prognostic factors for DFS, while differentiation (HR, 7.904; P ≤ 0.001) and chemotherapy (HR, 0.344; P = 0.038) were significant prognostic factors for OS.
Conclusion
Tumor differentiation, laparoscopic surgery, and adjuvant chemotherapy were found to be significant prognostic factors in patients with T4 colon cancer. Adjuvant chemotherapy and curative resections by laparoscopy might improve the prognosis in these patients.

Purpose:
Adjuvant chemotherapy (AC) is recommended for patients with stage II colorectal cancer with adverse features. However, the effect of adjuvant treatment in elderly patients with high-risk stage II colorectal cancer remains controversial. This study aimed to investigate the oncologic outcomes in elderly high-risk stage II colorectal cancer patients who underwent curative resection with or without AC.
Methods:
Patients aged over 70 years having stage II colorectal adenocarcinoma with at least 1 adverse feature who underwent radical surgery between 2008 and 2017 at a single center were included. We compared recurrence-free survival (RFS) and overall survival (OS) between patients who received more than 80% of the planned AC cycle (the AC+ group) and those who did not receive it (the AC− group).
Results:
The AC+ and AC– group contained 46 patients and 50 patients, respectively. The log-rank test revealed no significant intergroup differences in RFS (P = 0.083) and OS (P = 0.122). In the subgroup of 27 patients with more than 2 adverse features, the AC+ group (n = 16) showed better RFS (P = 0.006) and OS (P = 0.025) than the AC− group. In this subgroup, AC was the only significant factor affecting RFS in the multivariate analysis (P = 0.023). AC was significantly associated with OS (P = 0.033) in the univariate analysis, but not in the multivariate analysis (P = 0.332).
Conclusion
Among elderly patients with stage II high-risk colorectal cancer, the AC+ group did not show better RFS or OS than the AC− group. However, selected patients with more than 2 adverse features might benefit from AC.

BACKGROUND/AIMS: Diagnostic or thepapeutic endoscopic retrograde cholangiopancreatography (ERCP) is the mainstream for the pancreaticobiliary disease. However, the ERCP related complications are serious and sometimes fatal to the patients. We have reviewed our experiences of the operative management for the ERCP injury. METHODS: Medical records of 13 patients who underwent laparotomic surgical intervention for various ERCP injuries from March 1996 to August 2002 at Department of Surgery, the Catholic University of Korea were reviewed. RESULTS: The age range of the patients was from 28 to 85 years. There were 5 females and 8 males. 6 patients showed the duodenal perforations and 4 patients suffered from bleedings around the ampulla of Vater. One of the 4 bleeding patients had huge expanding submucosal hematomas throughout the entire duodenum. We found massive retroperitoneal extraluminal air density in one patient but we could not find any leakage of the contrast media during the upper gastrointestinal series, however, this patient complained aggravated peritoneal irritation sign, so we explored the abdomen. Most of the patients had free abdominal or retroperitoneal air shadows (n=7) on plain chest or abdominal X-ray. We diagnosed the uncontrolled bleeding from the sphincterotomy site using the gastroduodenal fiberscopes in 3 patients. On the computed tomogaphic images, one patient showed a huge duodenal hematoma, another one had a retroperitoneal fluid collection and another one revealed a retroperitoneal air shadow. One patient showed aggravated pancreatitis on the serial CT scan and finally the patient developed a hemorrhagic necrotizing pancreatitis, then we explored the abdomen and tried peripancreatic drainage but we lost the patient in 19 postoperative day due to sepsis. The other 12 patients survived by the various surgical procedures. For the 6 patients, we performed duodenotomic sphincteroplasty, tube duodenostomy and biliary drainage with T-tube. One patient survived with Whipple's procedure, one patient improved by the pyloric exclusion and one patient cured with the duodenal diverticulization. Other procedures were primary repair of the duodenum, transduodenal sphincteroplasty and just cholecystectomy and T-tube choledochostomy. CONCLUSION: There was tendency to uneventful improvement of patients by the early detection and urgent laparotomic surgical intervention of the ERCP complication.

Cystic lymphangioma of the spleen is extremely rare disease and the treatment is always surgical. In the present report we describe a symptomatic splenic cystic lymphangioma in a 44 year-old female. Clinical examination revealed palpable mass in the left upper quadrant of the abdomen. Abdominal CT scan revealed enlarged spleen with multiple, variable sized cysts. A few cysts had peripheral calcification. Open splenectomy was performed and histologic examination permitted the accurate diagnosis to be made. In case of multiple cystic enlargement of spleen, consider the possibility of cystic lymphangioma of the spleen and splenectomy.
