RESUMEN
INTRODUCTION: Diagnostic laparoscopy with appendicectomy (LA) has become the accepted method of investigation and treatment of appendicitis. However, concerns remain in cases of complicated appendicitis when many advocate conversion to an open procedure (LCOA) owing to the risk of complications. The aim of this study was to look for factors that could predict complications occurring in patients undergoing appendicectomy. METHODS: Data inclusive of all consecutive appendicectomies over a two-year period were retrieved from the computerised theatre database. Clinical details including admission inflammatory markers, complications, severity (final pathology) and length of stay were collected from the discharge letter. Readmissions were identified as those hospital identifiers had a second set of admission dates and/or a second discharge letter. RESULTS: During the 2-year study period, 517 appendicectomies were performed. Of these, 429 patients (83%) had LA and the remaining 88 (17%) had LCOA. The LA group had a mean age of 28 years (range: 2-86 years) and a mean C-reactive protein (CRP) level of 71 mg/l (range: 0-480 mg/l) while the LCOA group had a mean age of 46 years (range: 11-92 years) and a mean CRP level of 162 mg/l (range: 3-404 mg/l). These differences in age and CRP were significant (p<0.001). LA patients were less likely to have complications overall (22% vs 52%, p=0.015). Complications were independently more than twice as common with established inflammation with a CRP level of >150 mg/l (p<0.05). CONCLUSIONS: A high preoperative CRP level predicts an increased rate of postoperative complication due to established inflammation and/or infection. This raises the question of whether we should be offering primary open appendicectomies to patients with a CRP level of >150 mg/l.

BACKGROUND: Although laparoscopic adjustable gastric bands (LAGBs) have been shown to be efficacious, their long-term usefulness has been questioned. This study examined the fate of LAGBs in a unit with over a decade of experience in their use. Patient factors related to the need for, and timing of, band removal were investigated. METHODS: A prospectively maintained database was used to identify all patients with a LAGB. Patient demographics, need for band removal and band survival were examined. Logistic regression modelling was done and Kaplan-Meier curves were calculated for band survival. RESULTS: Between 2000 and 2012, 674 bands were placed in 665 patients. Of these, 143 (21.2 per cent) were removed. There was no difference in rates of removal by sex (P = 0.910). The highest rates of removal were in patients aged less than 40 years (26.7 per cent), and those with a BMI greater than 60 kg/m2 (28.6 per cent). Earlier band removal was seen in younger patients (P = 0.002). Rates of removal increased linearly by earlier year of placement. Of bands placed 4 or more years previously, 35.0 per cent required removal. Eighty-three patients (58.0 per cent) who had a LAGB removed went on to have a further bariatric procedure (band to bypass, 66; band to sleeve, 17). CONCLUSION: Even in experienced hands LAGB does not appear to be a definitive solution. In a large number of patients there appears to be a finite 'band life', with the majority of patients requiring conversion to a further bariatric procedure.

INTRODUCTION: Appendicitis in pregnancy (AIP) is the most common nonobstetric cause of an acute abdomen requiring surgical intervention. Diagnostic difficulties arising from gestational symptoms compound the risk of foetal loss after negative appendicectomy and exponentially increase the risk to mother and foetus with delay in genuine cases. In this article, we investigate the symptoms and signs of AIP and attempt to identify consistent clinical features and review the role of imaging in diagnosis. METHOD: MEDLINE and PubMed were searched for case-control studies recording preoperative symptoms/signs suggestive of AIP, as well as appendiceal pathology. Combined likelihood and odds ratios (OR) were created for clinical features across homogenous papers. Papers examining the use of laparoscopy, ultrasound (US), computerized tomography (CT) and magnetic resonance imaging (MRI) were assessed qualitatively. RESULTS: Seven papers met the inclusion criteria for the analysis of consistent clinical features (450 patients). The only symptoms or signs significantly associated with a diagnosis of appendicitis were nausea (OR: 2.21, 95%CI: 1.34-3.66), vomiting (OR: 0.82-15.6 range) and peritonism (OR: 1.80, 95%CI: 1.06-3.04). US, CT and MRI have all been used to successfully diagnose AIP. Laparoscopic appendicectomy has been safely undertaken in pregnancy. CONCLUSION: Appendicitis will continue to challenge the diagnostic acumen of surgeons. Whilst useful, consensus regarding the safety of laparoscopy, CT and MRI in pregnancy is yet to be achieved.
