RESUMO
OBJECTIVE: The aim of this study was to compare the outcome of the hemorrhoidal artery ligation procedure for hemorrhoidal disease with and without use of the provided Doppler transducer. BACKGROUND: Hemorrhoidal artery ligation, known as HAL (hemorrhoidal artery ligation) or THD (transanal hemorrhoidal dearterialization) procedure, is a common treatment modality for hemorrhoidal disease in which a Doppler transducer is used to locate the supplying arteries that are subsequently ligated. It has been suggested that the use of the Doppler transducer does not contribute to the beneficial effect of these ligation procedures. METHODS: The authors conducted a single-blinded randomized clinical trial and assigned a total of 82 patients with grade II and III hemorrhoidal disease to undergo either a HAL/THD procedure without use of the Doppler transducer (non-Doppler group, 40 patients) or a conventional HAL/THD procedure (Doppler group, 42 patients). Primary endpoint was improvement of self-reported clinical parameters after both 6 weeks and 6 months. This study is registered at trialregister.nl and carries the ID number: NTR2139. RESULTS: After 6 weeks and 6 months in both the non-Doppler and the Doppler group, significant improvement was observed with regard to blood loss, pain, prolapse, and problems with defecation (P < 0.05). The improvement of symptoms between both groups did not differ significantly (P > 0.05), except for prolapse, which improved more in the non-Doppler group (P = 0.047). There were more complications and unscheduled postoperative events in the Doppler group (P < 0.0005). After 6 months, 31% of the patients in the non-Doppler group and 21% in the Doppler group reported completely complaint free (P = 0.313). CONCLUSIONS: The authors' findings confirm that the hemorrhoidal artery ligation procedure significantly reduces signs and symptoms of hemorrhoidal disease. The authors' data also show that the Doppler transducer does not contribute to this beneficial effect.

BACKGROUND: The median laparotomy is frequently used by abdominal surgeons to gain rapid and wide access to the abdominal cavity with minimal damage to nerves, vascular structures and muscles of the abdominal wall. However, incisional hernia remains the most common complication after median laparotomy, with reported incidences varying between 2-20%. Recent clinical and experimental data showed a continuous suture technique with many small tissue bites in the aponeurosis only, is possibly more effective in the prevention of incisional hernia when compared to the common used large bite technique or mass closure. METHODS/DESIGN: The STITCH trial is a double-blinded multicenter randomized controlled trial designed to compare a standardized large bite technique with a standardized small bites technique. The main objective is to compare both suture techniques for incidence of incisional hernia after one year. Secondary outcomes will include postoperative complications, direct costs, indirect costs and quality of life. A total of 576 patients will be randomized between a standardized small bites or large bites technique. At least 10 departments of general surgery and two departments of oncological gynaecology will participate in this trial. Both techniques have a standardized amount of stitches per cm wound length and suture length wound length ratio's are calculated in each patient. Follow up will be at 1 month for wound infection and 1 year for incisional hernia. Ultrasound examinations will be performed at both time points to measure the distance between the rectus muscles (at 3 points) and to objectify presence or absence of incisional hernia. Patients, investigators and radiologists will be blinded during follow up, although the surgeon can not be blinded during the surgical procedure. CONCLUSION: The STITCH trial will provide level 1b evidence to support the preference for either a continuous suture technique with many small tissue bites in the aponeurosis only or for the commonly used large bites technique.

BACKGROUND: The aim of this study was to evaluate the impact of surgical subspecialization on the outcome of laparoscopic cholecystectomy. METHODS: The retrospective cohort study included all consecutive patients who underwent laparoscopic cholecystectomy between June 2002 and June 2009 in a major teaching hospital. Patients were divided into two groups: those operated on by laparoscopy-oriented surgeons (more than 50 laparoscopic procedures annually) and those operated on by nonlaparoscopy surgeons. Surgeries were divided into two groups as well: elective surgery for cholelithiasis and emergency surgery for acute cholecystitis. Conversion rate, operating time, complications, and length of hospital stay were analyzed and compared between both groups. RESULTS: During the study period 1509 patients underwent laparoscopic cholecystectomy for symptomatic gallstone disease. A laparoscopic surgeon performed the procedure on 893 patients, and 616 patients were operated on by nonlaparoscopy surgeons. For elective surgeries the laparoscopic interest of the surgeon had no influence on the outcome of the procedure. In patients with acute cholecystitis, a significant difference in conversion rate (3.6 vs. 15.6%, p = 0.003) and operating time (68 vs. 76 min, p = 0.02) favored the laparoscopic surgeons. CONCLUSIONS: Patients who present with acute cholecystitis have a greater chance of a laparoscopically completed cholecystectomy if operated on by a laparoscopy-oriented surgeon.

BACKGROUND: Acute appendicitis is one of the most common indications for emergency surgery. In patients with a complex appendicitis, prolonged antibiotic prophylaxis is recommended after appendectomy. There is no consensus regarding the optimum duration of antibiotics. Guidelines propose 3 to 7 days of treatment, but shorter courses may be as effective in the prevention of infectious complications. At the same time, the global issue of increasing antimicrobial resistance urges for optimization of antibiotic strategies. The aim of this study is to determine whether a short course (48 h) of postoperative antibiotics is non-inferior to current standard practice of 5 days. METHODS: Patients of 8 years and older undergoing appendectomy for acute complex appendicitis - defined as a gangrenous and/or perforated appendicitis or appendicitis in presence of an abscess - are eligible for inclusion. Immunocompromised or pregnant patients are excluded, as well as patients with a contraindication to the study antibiotics. In total, 1066 patients will be randomly allocated in a 1:1 ratio to the experimental treatment arm (48 h of postoperative intravenously administered (IV) antibiotics) or the control arm (5 days of postoperative IV antibiotics). After discharge from the hospital, patients participate in a productivity-cost-questionnaire at 4 weeks and a standardized telephone follow-up at 90 days after appendectomy. The primary outcome is a composite endpoint of infectious complications, including intra-abdominal abscess (IAA) and surgical site infection (SSI), and mortality within 90 days after appendectomy. Secondary outcomes include IAA, SSI, restart of antibiotics, length of hospital stay (LOS), reoperation, percutaneous drainage, readmission rate, and cost-effectiveness. The non-inferiority margin for the difference in the primary endpoint rate is set at 7.5% (one-sided test at É 0.025). Both per-protocol and intention-to-treat analyses will be performed. DISCUSSION: This trial will provide evidence on whether 48 h of postoperative antibiotics is non-inferior to a standard course of 5 days of antibiotics. If non-inferiority is established, longer intravenous administration following appendectomy for complex appendicitis can be abandoned, and guidelines need to be adjusted accordingly.

Significance: Large variation and many controversies exist regarding the treatment of, and care for, acute wounds, especially regarding wound cleansing, pain relief, dressing choice, patient instructions, and organizational aspects. Recent Advances: A multidisciplinary team developed evidence-based guidelines for the Netherlands using the AGREE-II and GRADE instruments. A working group, consisting of 17 representatives from all professional societies involved in wound care, tackled five controversial issues in acute-wound care, as provided by any caregiver throughout the whole chain of care. Critical Issues: The guidelines contain 38 recommendations, based on best available evidence, additional expert considerations, and patient experiences. In summary, primarily closed wounds need no cleansing; acute open wounds are best cleansed with lukewarm (drinkable) water; apply the WHO pain ladder to choose analgesics against continuous wound pain; use lidocaine or prilocaine infiltration anesthesia for wound manipulations or closure; primarily closed wounds may not require coverage with a dressing; use simple dressings for open wounds; and give your patient clear instructions about how to handle the wound. Future Directions: These evidence-based guidelines on acute wound care may help achieve a more uniform policy to treat acute wounds in all settings and an improved effectiveness and quality of wound care.
RESUMO
We present a case of a patient with a spinal epidural abscess (SEA) and meningitis following short-term epidural catheterisation for postoperative pain relief after a laparoscopic sigmoid resection. On the fifth postoperative day, 2â days after removal of the epidural catheter, the patient developed high fever, leucocytosis and elevated C reactive protein. Blood cultures showed a methicillin-sensitive Staphylococcus aureus infection. A photon emission tomography scan revealed increased activity of the spinal canal, suggesting S. aureus meningitis. A gadolinium-enhanced MRI showed a SEA that was localised at the epidural catheter insertion site. Conservative management with intravenous flucloxacillin was initiated, as no neurological deficits were seen. At last follow-up, 8â weeks postoperatively, the patient showed complete recovery.

The interdisciplinary evidence-based guideline 'Wound Care' covers the treatment and management of acute wounds in adults and children and by all wound care disciplines. This guideline answers 5 basic questions with 38 recommendations covering wound cleansing, pain relief, instructing the patient, various dressings and the organisational aspects of wound care. The guideline recommendations include not to cleanse wounds that are primarily closed, to cleanse acute open wounds with clean tap water, to use the WHO pain ladder as the basis for the choice of analgesics for continuous wound pain, to administer lidocaine or prilocaine for localized pain relief during manipulation, not to cover primarily closed wounds with dressings, to use simple dressings for open wounds and to give the patient clear instructions. The guideline also advises about wound registration, documentation and hand-over of wound care, and recommends making clear agreements about referrals and responsibilities.

INTRODUCTION: Intraabdominal abscesses are a common complication after appendectomy, especially in children. In this study, we describe the incidence and course of this complication in relation to the cultured pathogens found in intraabdominal abscesses. METHODS: The charts of all patients between 1 and 18 years of age undergoing appendectomy in 3 hospitals between January 2006, and July 2009, were retrospectively reviewed. Presence of an intraabdominal abscess was confirmed with abdominal ultrasound examination. We collected all details concerning the appendectomy, pus cultures, and postoperative course in these patients. RESULTS: Two hundred fifty-nine patients underwent appendectomy during the study period. Subsequently, abdominal ultrasound studies showed an intraabdominal abscess in 18 (7%) patients. Intraabdominal abscesses developed more frequently after perforated appendicitis (23%) than after simple appendicitis (2%). The incidence of postoperative abscesses did not differ significantly between open (5.6%) or laparoscopic (6.3%) appendectomy. However, the rate was high (38%) in the patients in whom the appendectomy was converted from laparoscopic to open. In 15 out of the 18 patients with a postoperative abscess drainage was performed. In pus cultures of the drained abscesses Streptococcus milleri and Escherichia coli were the most commonly isolated pathogens. Presence of S milleri was associated with prolonged hospital stay (13.9 versus 9.0 days, P = .105) and prolonged antibiotic treatment (11.3 versus 4.8 days, P = .203). CONCLUSIONS: The incidence of intraabdominal abscesses is high after perforated appendicitis in children (23%). Our data suggest that the presence of S milleri correlates with a more complicated postoperative course after appendectomy in children.

Every year, over 2500 unnecessary appendectomies are carried out in the Netherlands. At the initiative of the Dutch College of Surgeons, the evidence-based guideline on the diagnosis and treatment of acute appendicitis was developed. This guideline recommends that appendectomy should not be carried out without prior imaging. Ultrasonography is the recommended imaging technique in patients with suspected appendicitis. After negative or inconclusive ultrasonography, a CT scan can be carried out. Appendectomy is the standard treatment for acute appendicitis; this can be done either by open or laparoscopic surgery. The first choice treatment of appendicular infiltrate is conservative treatment.

OBJECTIVE: To evaluate the effect of the use of ultrasonography (US) and optional computed tomography (CT) or diagnostic laparoscopy on the percentage of unnecessary appendectomies in patients with suspected acute appendicitis. DESIGN: Prospective and comparison with a historical control group. METHOD: Following the introduction of ultrasound imaging as an initial step, the outcomes in all patients presenting with suspected appendicitis in the emergency department were prospectively collected during a period of 18 months (July 2006-December 2007). Results were compared to retrospectively collected data on all patients who had undergone appendectomy for acute appendicitis in 2001, before the introduction of this imaging investigation. RESULTS: Of the 312 consecutive patients in the emergency department with suspected acute appendicitis, the condition was excluded in 51 patients following clinical and laboratory investigation. The diagnostic algorithm was applied in 239 of the 261 patients (92%). All of them had initial US, followed by additional CT in 75 patients (31%) and diagnostic laparoscopy in 12 patients (5%). Appendectomy was performed in 130 patients, and 8 (6%) of the appendices were shown to be healthy following pathological investigation. Before the implementation of preoperative imaging 36 of the 170 appendices (21%) were healthy. Following the introduction of imaging techniques in accordance with the guideline there was a significant reduction in the percentage of unnecessary appendectomies (21% versus 6%; p < 0,001). The complete supplementary diagnostic algorithm had a positive and negative predictive value of respectively 90% and 98% for acute appendicitis. CONCLUSION: Structural implementation of US with optional CT and diagnostic laparoscopy in patients with suspected acute appendicitis resulted in a lower percentage of unnecessary appendectomies.

OBJECTIVES: The objective was to evaluate the diagnostic accuracy of clinical features and laboratory test results in detecting acute appendicitis. METHODS: Clinical features and laboratory test results were prospectively recorded in a consecutive series of 1,101 patients presenting with abdominal pain at the emergency department (ED) in six hospitals. Likelihood ratios (LRs) and the areas under the receiver operating characteristic curve (AUC) were calculated for the individual features. Variants of clinical presentation, based on different combinations of clinical features, were investigated and the accuracies of combinations of clinical features were evaluated. RESULTS: The discriminative power (AUC) of the individual features in patients with suspected appendicitis ranged from 0.50 to 0.65. For five of the 23 predictor sets, the accuracy for appendicitis was more than 85%. This accuracy was only found in male patients. The relative frequency of these predictor sets ranged from 2% to 13% of patients with suspected appendicitis. A combination of the clinical features migration of pain to the right lower quadrant (RLQ), and direct tenderness in the RLQ, was present in only 28% (120/422) of clinically suspected patients, of whom no more than 85 patients had appendicitis (71%). A "classical" presentation (combination of migration of pain to the RLQ, tenderness in the RLQ, and rigidity) occurred in only 6% (25/422) of patients with suspected appendicitis and yielded an accuracy of 100% in males but only 46% in females. CONCLUSIONS: The discriminative power (AUC) of individual clinical features and laboratory test results for appendicitis was weak in patients with suspected appendicitis. Combinations of clinical features and laboratory tests with high diagnostic accuracy are relatively infrequent in patients with suspected appendicitis.

Ursodeoxycholic acid (UDCA) and impaired gallbladder motility purportedly reduce biliary pain and acute cholecystitis in patients with gallstones. However, the effect of UDCA in this setting has not been studied prospectively. This issue is important, as in several countries (including the Netherlands) scheduling problems result in long waiting periods for elective cholecystectomy. We conducted a randomized, double-blind, placebo-controlled trial on effects of UDCA in 177 highly symptomatic patients with gallstones scheduled for cholecystectomy. Patients were stratified for colic number in the preceding year (<3: 32 patients; > or =3: 145 patients). Baseline postprandial gallbladder motility was measured by ultrasound in 126 consenting patients. Twenty-three patients (26%) receiving UDCA and 29 (33%) receiving placebo remained colic-free during the waiting period (89 +/- 4; median [range]: 75[4-365] days) before cholecystectomy (P = .3). Number of colics, non-severe biliary pain, and analgesics intake were comparable. A low number of prior colics was associated with a higher likelihood of remaining colic-free (59% vs. 23%, P < .001), without effects on the risk of complications. In patients evaluated for gallbladder motility, 57% were weak and 43% were strong contractors (minimal gallbladder volume > respectively < or = 6 mL). Likelihood to remain colic-free was comparable in strong and weak contractors (31% vs. 33%). In weak contractors, UDCA decreased likelihood to remain colic-free (21% vs. 47%, P = .02). In the placebo group, 3 preoperative and 2 post-cholecystectomy complications occurred. In contrast, all 4 complications in the UDCA group occurred after cholecystectomy. In conclusion, UDCA does not reduce biliary symptoms in highly symptomatic patients. Early cholecystectomy is warranted in patients with symptomatic gallstones.

Acute pancreatitis is a severe complication of gallstones with considerable mortality. We sought to explore the potential risk factors for biliary pancreatitis. We compared postprandial gallbladder motility (via ultrasonography) and, after subsequent cholecystectomy, numbers, sizes, and types of gallstones; gallbladder bile composition; and cholesterol crystallization in 21 gallstone patients with previous pancreatitis and 30 patients with uncomplicated symptomatic gallstones. Gallbladder motility was stronger in pancreatitis patients than in patients with uncomplicated symptomatic gallstones (minimum postprandial gallbladder volumes: 5.8 +/- 1.0 vs. 8.1 +/- 0.7 mL; P = .005). Pancreatitis patients had more often sludge (41% vs. 13%; P = .03) and smaller and more gallstones than patients with symptomatic gallstones (smallest stone diameters: 2 +/- 1 vs. 8 +/- 2 mm; P = .001). Also, crystallization occurred much faster in the bile of pancreatitis patients (1.0 +/- 0.0 vs. 2.5 +/- 0.4 days; P < .001), possibly because of higher mucin concentrations (3.3 +/- 1.9 vs. 0.8 +/- 0.2 mg/mL; P = .04). No significant differences were found in types of gallstones, relative biliary lipid contents, cholesterol saturation indexes, bile salt species composition, phospholipid classes, total protein or immunoglobulin (G, M, and A), haptoglobin, and alpha-1 acid glycoprotein concentrations. In conclusion, patients with small gallbladder stones and/or preserved gallbladder motility are at increased risk of pancreatitis. The potential benefit of prophylactic cholecystectomy in this patient category has yet to be explored.

AIMS: The objective of this population-based, retrospective cohort study was to investigate the incidence and initial antibiotic treatment of secondary intra-abdominal infections (sIAI) and to assess whether inappropriate initial antibiotic therapy affects patient outcomes. METHODS: All patients hospitalized for sIAI (1995-1998) were identified in the PHARMO Record Linkage System, a patient-centric database including pharmacy dispensing records from community pharmacies linked to hospitalization records in the Netherlands. Complementary in-hospital antibiotic drug use was obtained from the computerized inpatient pharmacy files. The patient outcomes considered were switch to second-line antibiotic treatment, re-operation, and death. In addition, a composite variable clinical failure was constructed based on the above-mentioned outcomes. Furthermore, the effect of clinical failure on length of hospital stay and costs of hospitalization was assessed. Associations between appropriateness of initial antibiotic treatment and outcomes were estimated using multivariate logistic and linear regression models. RESULTS: In the source population of 228,000 persons, 175 cases were classified as sIAI (mean age 49.3 +/- 24.5, 50.9% male) resulting in an incidence of 2.3/10,000 person-years [95% confidence interval (CI) 2.0, 2.7]. Initial antibiotic treatment was appropriate for 84% of the cases. The risk of clinical failure was 17.1%. Inappropriate initial antibiotic treatment increased the risk of clinical failure 3.4-fold (95% CI 1.3, 9.1). Length of hospital stay and costs of hospitalization were significantly increased for patients with clinical failure. CONCLUSIONS: Inappropriate choice of initial antibiotic therapy in sIAI patients leads to more clinical failure resulting in a longer hospital stay and higher costs of hospitalization compared with appropriate initial antibiotic therapy.

OBJECTIVES: Pancreatitis is a severe complication of gallstone disease with considerable mortality. Small gallstones may increase the risk of pancreatitis. Our aims were to evaluate potential association of small stones with pancreatitis and potential beneficial effects of prophylactic cholecystectomy. METHODS: Stone characteristics were determined in patients with biliary pancreatitis (115), obstructive jaundice due to gallstones (103), acute cholecystitis (79), or uncomplicated gallstone disease (231). Sizes and numbers of gallbladder and bile duct stones were determined by ultrasonography and endoscopic retrograde cholangiopancreatography, respectively. Effects of prophylactic cholecystectomy were assessed by decision analyses with a Markov model and Monte Carlo simulations. RESULTS: Patients with pancreatitis or obstructive jaundice had more and smaller gallbladder stones than those with acute cholecystitis or uncomplicated disease (diameters of smallest stones: 3 +/- 1, 4 +/- 1, 8 +/- 1, and 9 +/- 1 mm, respectively, p < 0.01). Bile duct stones were smaller in case of pancreatitis than in obstructive jaundice (diameters of smallest stones: 4 +/- 1 vs 8 +/- 1, p < 0.01). Multivariate analysis identified old age and small stones as independent risk factors for pancreatitis. Decision analysis in a representative group of patients with small (Assuntos
