Antibiotics in General Surgery

PURPOSE: Although many patients receive antibiotic therapy for uncomplicated appendicitis, the relatively high treatment failure and recurrence rates are problematic. We assumed that patients with appendicitis and appendiceal diameters ≤ 10 mm, have better outcomes. The purpose of this prospective non-randomized study was to assess the outcomes of antibiotic therapy in patients with uncomplicated appendicitis and appendiceal diameters ≤ 10 mm. METHODS: Over 2 years, we enrolled 119 patients who initially received antibiotic therapy...

BACKGROUND: Researchers have suggested that antibiotics could cure acute appendicitis. We assessed the efficacy of amoxicillin plus clavulanic acid by comparison with emergency appendicectomy for treatment of patients with uncomplicated acute appendicitis. METHODS: In this open-label, non-inferiority, randomised trial, adult patients (aged 18-68 years) with uncomplicated acute appendicitis, as assessed by CT scan, were enrolled at six university hospitals in France...

OBJECTIVES: To assess the safety and efficacy of antibiotics treatment for suspected acute uncomplicated appendicitis and to monitor the long term follow-up of non-operated patients. BACKGROUND: Right lower quadrant abdominal pain is a common cause of emergency department admission. The natural history of acute appendicitis nonoperatively treated with antibiotics remains unclear. METHODS: In 2010, a total of 159 patients [mean AIR (Appendicitis Inflammatory Response) score = 4...

IMPORTANCE: Ninety percent of cases of acute calculous cholecystitis are of mild (grade I) or moderate (grade II) severity. Although the preoperative and intraoperative antibiotic management of acute calculous cholecystitis has been standardized, few data exist on the utility of postoperative antibiotic treatment. OBJECTIVE: To determine the effect of postoperative amoxicillin plus clavulanic acid on infection rates after cholecystectomy. DESIGN, SETTING, AND PATIENTS: A total of 414 patients treated at 17 medical centers for grade I or II acute calculous cholecystitis and who received 2 g of amoxicillin plus clavulanic acid 3 times a day while in the hospital before and once at the time of surgery were randomized after surgery to an open-label, noninferiority, randomized clinical trial between May 2010 and August 2012...

Intussusception in adult is rare. The etiology is different from that of childhood. The most common cause of intussusception in adult is known as malignancy. When dealing with adult intussusception, surgical resection is usually warranted for correct diagnosis and proper treatment. This is a case report of cecocolic intussusception caused by an acute appendicitis in adult. The causes of cecocolic intussusception were reported as appendiceal adenocarcinoma, appendiceal mucocele, appendiceal adenoma, or idiopathic...

BACKGROUND: The aim of the study was to investigate the value of serum procalcitonin (PCT) as a predictor of early antibiotic treatment response in patients with acute appendicitis. Procalcitonin is a biochemical marker that increases rapidly in cases of bacterial infection and sepsis; however, the benefit of PCT as a diagnostic tool in acute appendicitis has not been confirmed. METHODS: Observations of PCT dynamics were conducted as part of a prospective clinical trial at Sahlgrenska University Hospital between May 2009 and February 2010 on adult patients with acute appendicitis treated with antibiotics as first-line therapy...

BACKGROUND AND AIM: The aim of this study was to review the literature regarding the use of pre- and/or postoperative antibiotics in the management of appendicitis, using data obtained from PubMed and the Cochrane Library. MATERIAL AND METHODS: A literature search was conducted using the terms "appendicitis" combined with "antibiotics." Studies were selected based on relevance for the evidence on prophylactic and postoperative treatment with regard to the route and duration of drug administration and the findings of surgery...

Acute calculous cholecystitis may progress in a variety of ways from mild cases treatable with (or even without) oral antibiotics to severe cases complicated by bile peritonitis that require emergency surgical or radiological intervention. A sample of bile should always be sent for microbial cultures to identify aerobic and anaerobic bacterial organisms. Empirically selected broad spectrum antibiotic therapy (with a defined duration, dosage and administration route) should be prescribed according to the severity of the cholecystitis, an associated history of recent antibiotic therapy, and local bacterial susceptibility patterns...

OBJECTIVE: Role of prophylactic antibiotics in Milligan Morgan hemorrhoidectomy - A prospective, randomized control trial. DESIGN: Randomized control trial. PLACE AND DURATION OF STUDY: Combined Military Hospital Malir, Bannu and HIT hospital Taxilla, September 2008 to February 2011. PATIENTS AND METHODS: Patients undergoing Milligan Morgan hemorrhoidectomy for grade III and IV hemorrhoids were randomized in 2 groups by using computer generated table...

INTRODUCTION: Laparoscopic surgeons in Great Britain and Ireland were surveyed to assess their use of antibiotic prophylaxis in elective laparoscopic cholecystectomy. This followed a Cochrane review that found no evidence to support the use of antibiotic prophylaxis in routine cases. METHODS: Data were collected on routine use of antibiotics in elective laparoscopic cholecystectomy, and how that was influenced by factors such as bile spillage, patient co-morbidities and surgeons' experience...

BACKGROUND: Studies on selective decontamination of the digestive tract (SDD) in elective gastrointestinal surgery have shown decreased rates of postoperative infection and anastomotic leakage. However, the prophylactic use of perioperative SDD in elective gastrointestinal surgery is not generally accepted. METHODS: A systematic review of randomized clinical trials (RCTs) was conducted to compare the effect of perioperative SDD with systemic antibiotics (SDD group) with systemic antibiotic prophylaxis alone (control group), using MEDLINE, Embase and the Cochrane Central Register of Controlled Trials...

BACKGROUND: Delayed primary (DPC) and primary (PC) wound closures have been applied in ruptured appendicitis, but results were controversial. This study aims at comparing the rate of superficial surgical site infection (SSI) in ruptured appendicitis between DPC and PC. METHODS: A retrospective cohort of ruptured appendicitis was conducted between October 2006 and November 2009. Demographic, operative findings and postoperative infection data were retrieved. The superficial SSI rates between groups were compared using an exact test...

BACKGROUND: The purpose of this study was to clarify the incidence and risk factors for incisional surgical site infections (SSI) in patients undergoing elective open surgery for colorectal cancer. METHODS: We conducted prospective surveillance of incisional SSI after elective colorectal resections performed by a single surgeon for a 1-year period. Variables associated with infection, as identified in the literature, were collected and statistically analyzed for their association with incisional SSI development...

BACKGROUND: In recent years, use of prosthetic material for inguinal hernia repair has increased dramatically. Tension-free repairs have gained popularity not only for recurrent or complicated hernias, but for primary hernia repairs as well. Although routine use of prophylactic antibiotics is not recommended in the Philippines for open nonimplant herniorrhaphy, there is little direct clinical evidence on which to base recommendations when implantable mesh is used. STUDY DESIGN: We conducted a prospective, randomized, double-blind, placebo-controlled trial comparing wound infection rates in 360 patients (180 received prophylactic antibiotics, 180 received a placebo) undergoing primary inguinal hernia repair electively using polypropylene mesh...

BACKGROUND: The efficacy of antibiotic prophylaxis for the prevention of surgical-site infection (SSI) after open tension-free inguinal hernia repair remains controversial. METHODS: A double-blind, randomized, placebo-controlled trial was conducted. Patients who underwent elective open mesh-plug hernia repair were eligible for randomization. In the antibiotic prophylaxis group, 1.0 g cefazolin was intravenously administrated 30 minutes before the incision. In the placebo group, an equal volume of sterile saline was administered...

BACKGROUND: Surgical intensive care unit (SICU) patients are known to be at high risk for venous thromboembolism (VTE). The 2005 Caprini Risk Assessment Model (RAM) predicts VTE risk in surgical patients. However, a physician's ability to accurately complete this RAM and the effect that inaccurate RAM completion might have on VTE risk remain unknown. STUDY DESIGN: Between 2009 and 2012, physicians completed a 2005 Caprini score for all SICU admissions at our institution...

BACKGROUND: The standard of care for acute uncomplicated diverticulitis today is antibiotic treatment, although there are no controlled studies supporting this management. The aim was to investigate the need for antibiotic treatment in acute uncomplicated diverticulitis, with the endpoint of recovery without complications after 12 months of follow-up. METHODS: This multicentre randomized trial involving ten surgical departments in Sweden and one in Iceland recruited 623 patients with computed tomography-verified acute uncomplicated left-sided diverticulitis...

BACKGROUND: The aim of this study was to assess the effect of antibiotic prophylaxis (AP) on postoperative infections in acute cholecystectomy. METHODS: The study was based on acute cholecystectomies registered in the nationwide Swedish Register for Gallstone Surgery and Endoscopic Retrograde Cholangiopancreatography (GallRiks) between 2006 and 2010. The association between AP and the risk of postoperative infectious complications was tested in a multivariable regression analysis, with stepwise addition of age, sex, duration of operation, indication for surgery, surgical approach (laparoscopic versus open) and American Society of Anesthesiologists (ASA) fitness grade as co-variables...

OBJECTIVE: To assess the effectiveness of antibiotic prophylaxis in mesh hernioplasty. BACKGROUND: Antibiotic prophylaxis use in mesh inguinal hernioplasty is controversial. Available evidence is nonconclusive because of the low number of clinical trials assessing its effectiveness. Some trials have a small sample size that could overestimate or underestimate the real effectiveness of this intervention. Meta-analysis is a good method to improve these methodological flaws...

IMPORTANCE: Surgical site infections can result in substantial morbidity following inpatient surgery. Little is known about serious infections following ambulatory surgery. OBJECTIVE: To determine the incidence of clinically significant surgical site infections (CS-SSIs) following low- to moderate-risk ambulatory surgery in patients with low risk for surgical complications. DESIGN, SETTING, AND PARTICIPANTS: Retrospective analysis of ambulatory surgical procedures complicated by CS-SSIs that require a postsurgical acute care visit (defined as subsequent hospitalization or ambulatory surgical visit for infection) using the 2010 Healthcare Cost and Utilization Project State Ambulatory Surgery and State Inpatient Databases for 8 geographically dispersed states (California, Florida, Georgia, Hawaii, Missouri, Nebraska, New York, and Tennessee) representing one-third of the US population...
