The implementation of the acute care surgery model in the management of patients with acute appendicitis - A 5-year single-center, retrospective experience: An observational study.

We conducted this study to assess the effects of the acute care surgery (ACS) model in the management of patients with acute appendicitis (AA) based on our 5-year single-center, retrospective experience. The current single-center, retrospective, observational study was conducted in a consecutive series of the patients with AA who had been surgically treated at a tertiary referral hospital in Seoul, Korea, between January 2016 and December 2020. At our institution, the ACS model was first introduced in March 2018.

Preoperative Intrathecal Morphine is Associated With Reduced Postoperative Pain, Agitation, and Delirium In Living Donor Kidney Transplantation Recipients.

Background: Postoperative delirium after organ transplantation can lead to increased length of hospital stay and mortality. Because pain is an important risk factor for delirium, perioperative analgesia with intrathecal morphine (ITM) may mitigate postoperative delirium development. We evaluated if ITM reduces postoperative delirium incidence in living donor kidney transplant (LDKT) recipients.

Emergency gastrointestinal tract operation associated with cytomegalovirus infection.

Purpose: Cytomegalovirus (CMV) infection is common in immunocompromised patients. Enterocolitis caused by CMV infection can lead to perforation and bleeding of the gastrointestinal (GI) tract, which requires emergency operation. We investigated the demographics and outcomes of patients who underwent emergency operation for CMV infection of the GI tract.

Clinical impact of lactate on postoperative pancreatic fistula after pancreaticoduodenectomy: A single-center retrospective study of 1,043 patients.

Background/objectives: Several hemodynamic markers have been studied to predict postoperative complication which is a risk factor for poor quality of life and prognosis. The aim of this study was to determine whether postoperative lactate clearance could affect clinical outcome based on complications in one surgical patient group.

Methods: We retrospectively reviewed data from all patients who underwent pancreaticoduodenectomy (PD) at Samsung Medical Center from January 2015 to December 2019.

Clinical significance of acute care surgery system as a part of hospital medical emergency team for hospitalized patients.

Purpose: Acute care surgery (ACS) has been practiced in several tertiary hospitals in South Korea since the late 2000s. The medical emergency team (MET) has improved the management of patients with clinical deterioration during hospitalization. This study aimed to identify the clinical effectiveness of collaboration between ACS and MET in hospitalized patients.

Non-occlusive mesenteric ischemia in critically ill patients.

Background: Non-occlusive mesenteric ischemia (NOMI) is a life-threatening acute condition that has an overall in-hospital mortality rate of up to 75%. Critically ill patients are often admitted to intensive care units (ICUs) due to shock, and these patients are frequently at risk of developing NOMI. The objective of this study was to determine the clinical features of critically ill patients with NOMI and evaluate the risk factors for in-hospital mortality among these patients.

Outcomes after Elective Open Abdominal Aortic Aneurysm Repair in Octogenarians Compared to Younger Patients in Korea.

Background: Although the first choice of treatment for abdominal aortic aneurysm (AAA) is endovascular aneurysm repair, especially in elderly patients, some patients require open surgical repair. The purpose of this study was to compare the mortality outcomes of open AAA repair between octogenarians and younger counterparts and to identify the risk factors associated with mortality.

Methods: All consecutive patients who underwent elective open AAA repair due to degenerative etiology at a single tertiary medical center between 1996 and June 2020 were included in this retrospective review.

Evaluating mortality and recovery of extreme hyperbilirubinemia in critically ill patients by phasing the peak bilirubin level: A retrospective cohort study.

Background: Hyperbilirubinemia is a devastating complication in patients admitted to an intensive care unit (ICU). The sequential organ failure assessment (SOFA) score classifies hyperbilirubinemia without further detailed analyses for bilirubin increase above 12 mg/dL. We evaluated whether the level of bilirubin increase in patients with extreme hyperbilirubinemia (total bilirubin ≥ 12 mg/dL) affects and also helps estimate mortality or recovery.

Clinical impact of massive transfusion protocol implementation in non-traumatic patients.

Background: Massive transfusion protocol (MTP) has been used to provide plasma and packed red blood cells (pRBCs) rapidly. MTP also has been adapted for non-traumatic patients. The effects of hospital-wide MTP implementation on clinical outcomes were reviewed.

Safety and feasibility of ultrasound-guided placement of peripherally inserted central catheter performed by neurointensivist in neurosurgery intensive care unit.

We evaluated the safety and feasibility of ultrasound-guided peripherally-inserted central venous catheters (PICC) by a neurointensivist at the bedside compared to fluoroscopy-guided PICC and conventional central venous catheter (CCVC). This was a retrospective study of adult patients who underwent central line placement and were admitted to the neurosurgical intensive care unit (ICU) between January 2014 and March 2018. In this study, the primary endpoint was central line-induced complications.

Recipient Age and Mortality After Liver Transplantation: A Population-based Cohort Study.

Background: The feasibility of liver transplantation (LT) in elderly recipients remains a topic of debate.

Methods: This cohort study evaluated the impact of recipient's age on LT outcome between January 2007 and May 2016 covered by the Korean National Health Insurance system (n = 9415). Multilevel regression models were used to determine the impact of recipient's age on in-hospital and long-term mortality after LT.

Association of body mass index with clinical outcomes for in-hospital cardiac arrest adult patients following extracorporeal cardiopulmonary resuscitation.

Background: Obesity might be associated with disturbance of cannulation in situation of extracorporeal cardiopulmonary resuscitation (ECPR). However, limited data are available on obesity in the setting of ECPR. Therefore, we investigated the association between body mass index (BMI) and clinical outcome in patients underwent ECPR.

Laparoscopic Liver Resection of Hepatocellular Carcinoma with a Tumor Size Larger Than 5 cm: Review of 45 Cases in a Tertiary Institution.

Introduction: Although laparoscopic liver resection (LLR) has developed rapidly, its usefulness for the treatment of large tumors is less clear, due to concerns about compromising oncological principles and patient safety. The purpose of this study was to explore the feasibility and safety of LLR for the treatment of hepatocellular carcinoma (HCC) with a tumor size larger than 5 cm.

Patients And Methods: From January 2007 to December 2014, we performed LLR in 45 patients with HCC with a tumor size ≥5 cm.

Predictors and patterns of recurrence after curative liver resection in intrahepatic cholangiocarcinoma, for application of postoperative radiotherapy: a retrospective study.

Background: The majority of patients with intrahepatic cholangiocarcinoma (IHCC) who undergo complete tumor resection subsequently develop tumor recurrence. The objectives of this study were to determine the risk factors for IHCC recurrence after curative (R0) liver resection and to identify the feasibility about postoperative adjuvant radiation therapy (RT).

Methods: We retrospectively reviewed patients who underwent liver resection for IHCC between April 1995 and December 2012 at Samsung Medical Center.

Mucinous cystic neoplasms of the pancreas with ovarian stroma.

Backgrounds: Mucinous cystic neoplasms (MCNs) of the pancreas are rare, but have recently been increasing in incidence. The aim of this retrospective clinical study was to elucidate the clinicopathological features and prognosis of MCNs with ovarian stroma at a single centre.

Methods: Using the presence of ovarian stroma as a requisite criterion for diagnosis of MCNs, the medical records of 47 surgically treated patients with MCNs from January 2004 to April 2011 were reviewed and classified according to the new 2010 World Health Organization classification.
