Elective day-case laparoscopic cholecystectomy: a formal assessment of the need for outpatient follow-up.

INTRODUCTION: Elective laparoscopic cholecystectomy (LC) is performed routinely as day-case surgery. Most hospital trusts have a policy of no routine postoperative outpatient follow-up although there are no formal guidelines on this. The aim of this retrospective study was to identify the incidence of complications, the degree of symptom resolution and patient satisfaction with a view to formally appraising the need for outpatient follow-up. METHODS: Patients who underwent LC in the period between February 2011 and June 2012 were contacted retrospectively by telephone. A standardised questionnaire was used to ascertain the incidence of surgical site infection (SSI), other complications, symptom resolution and patient satisfaction. RESULTS: A total of 211 responses were collected. The rate of SSI was 7.6% (n=16), with the only specific risk factor being smoking (p=0.027). All other complications had a combined incidence of 7% (n=15). There was complete resolution of symptoms in 64% of patients. Of the 36% of patients with residual symptoms, 45% described abdominal discomfort or pain, 41% described reflux symptoms and 14% complained of diarrhoea. Patient satisfaction was very high (96%), yet 33% of patients visited their general practitioner postoperatively in relation to their surgery. CONCLUSIONS: Patients are highly satisfied with elective day-case LC. However, SSI is not uncommon, occurring in 1 in 13 patients. Although the majority of patients experience complete symptom resolution, a significant proportion do not. In our experience, routine outpatient follow-up is not required. Nevertheless, the lack of formal follow-up may prove a missed learning opportunity, potentially resulting in inappropriate patient selection for surgery.

Staphylococcus aureus and other bacteria in untreated periodontitis.

Whether the subgingival microbiota differ between individuals with chronic and those with aggressive periodontitis, and whether smoking influences bacterial composition, is controversial. We hypothesized that the subgingival microbiota do not differ between sites in individuals with chronic or aggressive periodontitis, or by smoking status. Bacterial counts and proportional distributions were assessed in 84 individuals with chronic periodontitis and 22 with aggressive periodontitis. No differences in probing pocket depth by periodontal status were found (mean, 0.11 mm; 95% CI, 0.6 to 0.8, p = 0.74). Including Staphylococcus aureus, Parvimonas micra, and Prevotella intermedia, 7/40 species were found at higher levels in those with aggressive periodontitis (p < 0.001). Smokers had higher counts of Tannerella forsythia (p < 0.01). The prevalence of S. aureus in non-smokers with aggressive periodontitis was 60.5%. The null hypothesis was rejected, in that P. intermedia, S. aureus, and S. mutans were robust in diagnosing sites in individuals with aggressive periodontitis. S. aureus, S. sanguinis, and T. forsythia differentiated smoking status.

Comparison of the effects of cetylpyridinium chloride with an essential oil mouth rinse on dental plaque and gingivitis - a six-month randomized controlled clinical trial.

OBJECTIVE: To compare the effects of an experimental mouth rinse containing 0.07% cetylpyridinium chloride (CPC) (Crest Pro-Health) with those provided by a commercially available mouth rinse containing essential oils (EOs) (Listerine) on dental plaque accumulation and prevention of gingivitis in an unsupervised 6-month randomized clinical trial. MATERIAL AND METHODS: This double-blind, 6-month, parallel group, positively controlled study involved 151 subjects balanced and randomly assigned to either positive control (EO) or experimental (CPC) mouth rinse treatment groups. At baseline, subjects received a dental prophylaxis procedure and began unsupervised rinsing twice a day with 20 ml of their assigned mouthwash for 30 s after brushing their teeth for 1 min. Subjects were assessed for gingivitis and gingival bleeding by the Gingival index (GI) of Löe & Silness (1963) and plaque by the Silness & Löe (1964) Plaque index at baseline and after 3 and 6 months of rinsing. At 3 and 6 months, oral soft tissue health was assessed. Microbiological samples were also taken for community profiling by the DNA checkerboard method. RESULTS: Results show that after 3 and 6 months of rinsing, there were no significant differences (p=0.05) between the experimental (CPC) and the positive control mouth rinse treatment groups for overall gingivitis status, gingival bleeding, and plaque accumulation. At 6 months, the covariant (baseline) adjusted mean GI and bleeding sites percentages for the CPC and the EO rinses were 0.52 and 0.53 and 8.7 and 9.3, respectively. Both mouth rinses were well tolerated by the subjects. Microbiological community profiles were similar for the two treatment groups. Statistically, a significant greater reduction in bleeding sites was observed for the CPC rinse versus the EO rinse. CONCLUSION: The essential findings of this study indicated that there was no statistically significant difference in the anti-plaque and anti-gingivitis benefits between the experimental CPC mouth rinse and the positive control EO mouth rinse over a 6-month period.
