Laparoscopic cholecystectomy (LC) for complicated acute cholecystitis is associated with high rates of complications and conversion to open cholecystectomy. Percutaneous transhepatic gallbladder drainage (PTGBD) is a safe and effective treatment for acute inflammation of the gallbladder. This study was a retrospective analysis of patients who underwent an LC with or without PTGBD for complicated acute cholecystitis at our hospital between January 2002 and January 2007. Patients were classified i

Laparoscopic surgeons should be concerned about longer operation times and higher immediate postoperative pain scores in patients who undergo SA.

Purpose: Conventional laparoscopic appendectomy is performed using three ports, and single-port appendectomy is an attractive alternative in order to improve cosmesis. The aim of this study was to compare pain after transumbilical single-port laparoscopic appendectomy (SA) with pain after conventional three-port laparoscopic appendectomy (TA). Methods: From April to September 2011, 50 consecutive patients underwent laparoscopic appendectomy for simple appendicitis without gangrene or perforation

Perioperative outcomes in elderly patients who underwent LC seem to be influenced by the severity of gallbladder disease, and not by chronologic age. In octogenarians, LC should be performed at an earlier, uncomplicated stage of the disease whenever possible to improve perioperative outcomes.

BACKGROUND: Early oral feeding (EOF) following colorectal surgery can accelerate patient recovery and shorten hospital stay. However, some patients are intolerable to postoperative early oral feeding. The aim of this study was to evaluate the tolerability of EOF following laparoscopic colorectal cancer surgery and the effects of intravenous lidocaine. METHODS: The cohort in this randomized, placebo-controlled trial (ClinicalTrial.gov, NCT01346917) comprised of 77 patients undergoing elective lap

Although periodontal disease and gastrointestinal tract health are closely associated, few studies have investigated whether periodontitis is a risk factor for colorectal adenoma. The aim of this study was to investigate whether there is an association between periodontitis and the risk of colorectal adenoma in asymptomatic healthy people.From January 2013 to October 2015, we retrospectively enrolled 42,871 patients who underwent health screening at Kangbuk Samsung Hospital in South Korea. Demog

The objective of this study was to evaluate the results of radiofrequency ablation (RFA) for the treatment of metachronous hepatic metastases from gastric adenocarcinoma. Between January 2000 and February 2008, we retrospectively reviewed 7 cases for which RFA was performed for treating metachronous hepatic metastases after resection of the primary gastric adenocarcinoma. The median period between curative gastrectomy and metachronous hepatic metastasis was 14 months (range: 6 to 48 mo). The med

BACKGROUND AND AIM: In patients with gastric adenocarcinoma (GA), the most common double primary cancer is colorectal cancer. The aim of the present study was to evaluate the necessity of preoperative colonoscopy in patients with GA who have no symptoms of colorectal disease or any past/family history of colorectal cancer. MATERIALS: Colonoscopy was carried out in 205 patients before gastric surgery for treatment of GA. The prevalence of colorectal neoplasms (CRN, adenoma and adenocarcinoma) was

BACKGROUND: Appropriate palliation for unresectable pancreatic head cancer is most important. This study was undertaken to compare the survival of patients with biliary obstruction caused by unresectable pancreatic head cancer after surgical and non-surgical palliation. METHODS: We retrospectively reviewed 69 patients who underwent palliative treatment for unresectable pancreatic head cancer. Fifty-two patients with locally advanced disease (local vascular invasion) and 17 with distant metastati

BACKGROUND: Although hepatic resection is widely accepted as a proper modality for treating hepatocellular carcinoma (HCC), a majority of patients are unable to undergo surgical resection due to various tumor and patient factors. Radiofrequency ablation (RFA) has mostly been used as a therapeutic alternative to resection for treating HCC. The objective of this study was to evaluate the results of intraoperative RFA for HCCs in locations difficult for a percutaneous approach. METHODS: Eight patie

BACKGROUND: Postoperative bladder dysfunction often occurs after rectal cancer surgery, necessitating long-term urinary catheter drainage. The aim of this study was to evaluate the feasibility of early catheter removal and to propose scoring systems that may predict urinary dysfunction after laparoscopic rectal cancer surgery. METHODS: A total of 110 patients who underwent elective laparoscopic rectal cancer surgery were included in this prospective observational study. The urinary catheter was

Purpose: Partial mastectomy without immediate volume replacement can be associated with cosmetic failure. The aim of the present study was to assess cosmesis achieved in patients who underwent partial mastectomy and recon- struction using absorbable surgical mesh. Methods: We used absorbable surgical mesh (Polyglactin 910, Vicryl� ) to repair defects after performing partial mastectomy in 25 patients. Endoscopy-assisted partial mastectomy was performed with conservation of the whole skin of the

After abdominal surgery, PCN may be a feasible and effective concept in postoperative nutrition. In our Early Recovery after Surgery program, our PCN concept may reduce the time to tolerance of a regular diet and shorten the postoperative hospital stay.

OBJECTIVE: Management of esophagojejunostomy leakage (EJL) has a high mortality rate and increases length of hospital stay. The aim of this study was to evaluate the feasibility of early postoperative gastroduodenoscopy and stent insertion to control EJL after total gastrectomy for gastric adenocarcinoma. PATIENTS AND METHODS: Among 421 patients, 13 exhibited EJL. Of the 13 patients, 8 were treated with a covered self-expandable metal stent (SEMS) inserted by endoscopy and 5 patients were treate
