The inverse correlation of appendectomy and ulcerative colitis is well known, but the effect of appendectomy on the clinical course of ulcerative colitis remains unclear. Although the majority of opinions were negative for the therapeutic advantage of appendectomy in patients with ulcerative colitis, advocates for positive effect of appendectomy have been proposed in a few case reports and a pr...

PURPOSE Laparoscopic appendectomy has been recognized to have many advantages such as greater cosmetic results, less postoperative pain and shorter hospital stays. On the other hand, the cost of laparoscopic procedures is still more expensive than that of open procedures in Korea. The aim of this study is to compare clinical outcomes and hospital costs between open appendectomy and laparoscopic...

Little is known on the association between appendectomy and pyogenic liver abscess. The objective of this study was to investigate the association between appendectomy and the risk of pyogenic liver abscess in Taiwan.This population-based retrospective cohort study was conducted using the hospitalization dataset of the Taiwan National Health Insurance Program. There were 212,530 subjects age 20...

BACKGROUND AND OBJECTIVES This study describes perioperative patient safety outcomes comparing laparoscopic appendectomy with open appendectomy in the elderly population (defined as age≥65 years) during the diffusion of laparoscopic appendectomy into widespread clinical practice. METHODS We performed a cross-sectional analysis of patients undergoing open or laparoscopic appendectomy in the US...

HYPOTHESIS The incidence of postoperative intra-abdominal abscess is higher after laparoscopic compared with open appendectomy for perforated appendicitis. METHODS A historical cohort study of pediatric patients operated on for suspected appendicitis by open appendectomy or laparoscopic appendectomy compares the incidence of postoperative intra-abdominal abscess for each procedure. SETTING ...

BACKGROUND The objective of the study was to compare the outcomes of patients with generalised purulent peritonitis from complicated appendicitis diagnosed intraoperatively who were managed laparoscopically to those managed via the open approach in a single institution. METHOD Data were collected from all cases admitted at Sebokeng Hospital, Johannesburg, over the past two years (2008 and 200...

BACKGROUND Acute appendicitis is the most common cause of acute abdominal surgery. Despite nearly three decades comparing laparoscopic with laparotomic appendectomy, the available scientific evidence does not show consensus of opinion about the best access for the treatment of acute appendicitis. The transumbilical laparoscopic assisted appendectomy combines the advantages of laparoscopic acces...

CONTEXT The rates of appendiceal rupture and negative appendectomy in children remain high despite efforts to reduce them. Both outcomes are used as measures of hospital quality. Little is known about the factors that influence these rates. OBJECTIVE To investigate the association between hospital- and patient-level characteristics and the rates of appendiceal rupture and negative appendectom...

BACKGROUND Interval appendectomy after conservative treatment of appendicitis with tumor formation remains controversial. The purpose of this study was to evaluate the efficacy of interval appendectomy based on a cost-effectiveness analysis. METHODS This was a retrospective study including appendicitis patients with tumor formation who received conservative treatment at first admission to Tai...

Many studies have reported a possible association of an appendectomy with rheumatoid arthritis (RA). However, findings of the relationship between an appendectomy and RA remain inconsistent. Furthermore, all such studies were conducted in Western societies, and relevant studies on the relationship between an appendectomy and RA in Asian countries are still lacking. In this study, we investigate...
