Over the past decade, interest in exosomes as therapeutics has surged. In particular, stem-cell-derived exosomes may be more effective as a treatment for liver disease than the stem cells themselves. We have previously developed human chemically derived hepatic progenitors (hCdHs) from human hepatocytes. hCdHs can differentiate into hepatocytes and cholangiocytes, regenerating the liver in mouse models. In this study, we evaluated the mitigating effects of hCdHs-derived exosomes (hCdHs-exo) on liver damage and compared them with those of exosomes from bone marrow mesenchymal stem cells (BMMSCs-exo).

There is a high possibility of trauma patients being referred to an unsuitable medical institution for their rehabilitation treatment since the decision is made by them. This study sought to develop a standardized scale to evaluate the need for specialized rehabilitation in patients with multiple traumas and evaluate the effectiveness of the developed scale.

Liver transplantation (LT) in South Korea dates back to 1988. However, Asians may be reluctant to donate their organs because of the influence of their traditional religious and philosophical beliefs. We aimed to investigate the mortality and associated factors among patients admitted after LT in South Korea.

This study evaluates the knowledge of surgical residents in a tertiary hospital regarding the operational principles, potential complications, and mechanisms of energy devices used in surgery.

Over the past 3 years, approximately 23,000 emergency surgeries were performed annually in South Korea, accounting for >1% of all surgeries nationwide. With the growing necessity for treating these emergency cases with dedication and proficiency, acute care surgery (ACS) teams were appointed at various hospitals. Regarding the implications of the ACS team, many studies showed promising results with a shorter time from the emergency department (ED) to the operating room (OR), shorter length of stay, and fewer complications. This study aimed to demonstrate the overall effect of ACS implementation at a single institution in South Korea.

This study assessed the efficacy and safety of preoperative chlorhexidine gluconate (CHG) double-cleansing in reducing the incidence of surgical site infections (SSI) in surgical patients in neonatal intensive care units.

Right-sided tumors have been reported to have a poorer survival rate than left-sided tumors; however, there remains debate regarding whether sidedness is an independent prognostic factor in colorectal cancer liver metastasis (CRLM). This study aimed to assess the impact of sidedness on prognosis in resectable CRLM and to identify prognostic factors.

Intensive cytotoxic chemotherapy increases the risk of infection in patients with cancer by inducing bone marrow suppression and mucosal injury. Febrile neutropenia (FN) is the most important clinical adverse event in patients with cancer receiving cytotoxic chemotherapy. To prevent FN, standard precautions including hand and respiratory hygiene are generally recommended, but the exact effect of non-pharmacologic intervention has not been clearly proven in the clinical setting. We aimed to compare the incidence of FN between the pre-coronavirus disease 19 (COVID-19) era vs. the post-COVID-19 era.

During the coronavirus disease 2019 (COVID-19) pandemic, frequent perioperative interactions between patients and medical staff increased the risk of nosocomial infections. Total 1-day perioperative completion (TODPC) involves conducting preoperative evaluations, performing the operation, and facilitating discharge within a single day. This study aimed to evaluate the safety of TODPC in reducing perioperative contact by utilizing online and telephone appointment systems for inguinal hernia (IH) repairs.

Amyand's hernia (AH) is the name given to the type of hernia in which the appendix is found in a hernial sac. We aimed to share our clinical experience with a literature review for AH.

Bariatric surgery is the gold standard for the treatment of morbid obesity, but postoperative pain impedes recovery. Currently available pain-recovery treatments have patient safety concerns. This led to a noninferiority study of Welpass (Genewel Co., Ltd.) On-Q PainBuster (B. Braun), each used alongside a traditional method of continuous local anesthetic administration, in patients undergoing bariatric surgery.

This study aimed to investigate the optimal withdrawal time (WT) for initial surveillance colonoscopy after curative resection for colorectal cancer (CRC) by comparing anterior/low anterior resection (AR/LAR) and right hemicolectomy (RHC) groups.

Adrenocortical carcinoma (ACC) is a rare primary carcinoma originating in the adrenal gland with a poor prognosis and a high recurrence rate. This study evaluated the risk factors associated with recurrence in patients with early stage ACC after curative surgical resection.

Several studies have evaluated the impact of sarcopenic obesity (SO) on postoperative complications, including postoperative pancreatic fistula (POPF), in patients undergoing pancreatoduodenectomy (PD). Previous studies have shown that SO increases POPF, but it remains unclear whether SO increases postoperative complications. In this study, we aimed to determine the relationship between SO and immediate postoperative complications.

This study aimed to describe adult living donor liver transplantation (LDLT) for acute liver failure and evaluate its clinical significance by comparing its surgical and survival outcomes with those of deceased donor liver transplantation (DDLT).

Current guidelines recommend endoscopic resection for rectal neuroendocrine tumors (RNETs) under 10 mm. Incomplete resections necessitate salvage procedures, highlighting the need for complete R0 resection. This study evaluates the efficacy and safety of wide hot snare polypectomy (WHSP) compared to endoscopic submucosal dissection (ESD) and endoscopic mucosal resection (EMR) for the salvage treatment of small RNETs.

Preoperative localization plays an important role in secondary hyperparathyroidism (SHPT) surgery. The advantages of neck ultrasound (US) include high availability and low cost. However, the reported sensitivity of US is 54%-76%, and the reason for missed parathyroid glands (PGs) on US has been rarely addressed.

This study aimed to compare the results of patients who underwent anterior component separation techniques (ACST) and those who did not undergo component separation techniques (non-CST) in complicated ventral hernia repairs (VHRs) and to investigate the effect of these techniques on quality of life (QoL).

This study aimed to evaluate the long-term prognosis of contralateral central neck dissection (CND) in papillary thyroid cancer (PTC) patients with ipsilateral lateral neck metastasis. We compared the actual recurrence rate according to the extent of CND-ipsilateral and contralateral sides.

Laparoscopic right hemicolectomy is the standard surgical approach for treatment of right-sided colonic neoplasms. Although performed within a strict Enhanced Recovery After Surgery (ERAS) program, patients still develop postoperative ileus. The aim of this study was to describe the factors responsible for postoperative ileus after right hemicolectomy in a patient population with over 80% ERAS adherence.
