The evaluation of feasibility of ambulatory laparoscopic cholecystectomy using intraoperative instillation of bupivacaine: a retrospective observational study.

Purpose: This study aimed to compare outcomes of opioid patients-controlled anesthesia (PCA) and intraoperative local anesthesia in terms of postoperative pain, lab results, patient surveys, and discharge scores to evaluate the feasibility of ambulatory laparoscopic cholecystectomy (LC).

Methods: Patients who underwent LC for acute cholecystitis were assigned to the outpatient surgery (OPS) group or inpatient surgery (IPS) group according to the surgeon. In the OPS group, a mixture of bupivacaine and epinephrine was injected into trocar sites and sprayed on the surgical dissection field.

Impact of Visual Nutritional Indicator on the Nutritional Therapy in Intensive Care Unit.

Background: We wanted to evaluate if a visual nutritional indicator (VNI), which shows the total amount of calories and protein, can improve the quality of nutritional therapy (NT) and result in better clinical outcomes prospectively.

Materials And Methods: We randomly assigned patients to VNI or non-VNI (NVNI) groups. In the VNI group, VNI was attached to the patient's bed for the attending physician.

Surgical outcomes of laparoscopic sleeve gastrectomy by a single surgeon: Before and after learning curve in a non-tertiary low-volume bariatric center.

Background: In Korea, the need for bariatric surgery (BS) is increasing because of the increasing incidence of morbid obesity. There is no special training program for BS, and most BS are conducted in non-tertiary hospitals in capital area. We evaluated the surgical outcomes of laparoscopic sleeve gastrectomy (LSG) before and after the learning curve (LC) to prove that the barrier of entry for LSG is not very high.

Clinical outcomes of subtotal cholecystectomy performed for difficult cholecystectomy.

Purpose: Laparoscopic subtotal cholecystectomy (LSC) can be an alternative surgical technique for difficult cholecystectomies. Surgeons performing LSC sometimes leave the posterior wall of the gallbladder (GB) to shorten the operation time and avoid liver injury. However, leaving the inflamed posterior GB wall is a major concern.

Diversity of the definition of stable vital sign in trauma patients: results of a nationwide survey.

Background: Hemodynamic stability (HS) based on vital sign (VS) is thought to be the most useful criteria for successful non-operative management (NOM) of blunt spleen injury (BSI). However, a consistent definition of HS has not been established. We wanted to evaluate the definition of HS through conducting a nationwide survey and find the factors affectting diversity.

The safety and efficacy of percutaneous transhepatic gallbladder drainage in elderly patients with acute cholecystitis before laparoscopic cholecystectomy.

Purpose: Laparoscopic cholecystectomy (LC) is the standard management for acute cholecystitis. Percutaneous transhepatic gallbladder drainage (PTGBD) may be an alternative interim strategy before surgery in elderly patients with comorbidities. This study was designed to evaluate the safety and efficacy of PTGBD for elderly patients (>60 years) with acute cholecystitis.

Synchronous double primary squamous cell carcinoma and adenocarcinoma of the extrahepatic bile duct: a case report.

Introduction: Synchronous double cancers of the bile duct are exceptionally rare. We here report a case of synchronous squamous cell carcinoma and adenocarcinoma of the extrahepatic bile duct.

Case Presentation: A 67-year-old Asian man visited our clinic complaining of jaundice and dark urine.

Clinical outcome for laparoscopic cholecystectomy in extremely elderly patients.

Purpose: Extremely elderly patients who present with complicated gallstone disease are less likely to undergo definitive treatment. The use of laparoscopic cholecystectomy (LC) in older patients is complicated by comorbid conditions that are concomitant with advanced age and may increase postoperative complications and the frequency of conversion to open surgery. We aimed to evaluate the results of LC in patients (older than 80 years).

The advantages of early trauma team activation in the management of major trauma patients who underwent exploratory laparotomy.

Purpose: Trauma team activation (TTA) has been shown to have fundamental impact on trauma patients' outcomes. The purpose of this study was to evaluate the short-term outcomes of use of a new TTA protocol in the management of major trauma patients who underwent exploratory laparotomy.

Methods: The medical records of trauma patients who had been treated by the new TTA protocol (NT) over 18 months were compared with those of trauma patients treated by the old TTA protocol (OT) over 18 months.

The effect of laser diode irradiation on wound healing of rat skin.

Background: Light amplification by stimulated emission of radiation (LASER) diode irradiation (LDI) has some beneficial effects on the wound healing. However, little is known about the biochemical effect of LDI on wound healing. We have performed animal study to clarify the effect of LDI on wound healing based on microscopic findings.

Minimally invasive video-assisted kidney transplantation (MIVAKT).

Background: Minimally invasive surgery has been applied to nearly all fields of surgery due to its advantages such as reduced morbidity, a better cosmetic outcome, and early recovery. The recent advances in its technique have allowed us to use modified minimally invasive surgery technique in the field of kidney transplantation.

Materials And Methods: From January 2004 to March 2006, minimally invasive video-assisted kidney transplantation was carried out in 20 patients.

The effect of anchoring suture on the anastomotic blood flow in a rat model of human esophagojejunostomy.

Purpose: An impairment of anastomotic blood flow (ABF) and the resulting hypoxia readily lead to the complications such as leakage and stricture. We performed an animal study to evaluate the effect of anchoring suture for minimizing the impairment of ABF caused by tensile loading.

Materials And Methods: An end-to-side jejunojejunostomy was done in 20 rats, and this followed the modeling of a human end-to-side esophagojejunostomy.
