Intraperitoneal drain placement and outcomes after elective colorectal surgery: international matched, prospective, cohort study

Despite current guidelines, intraperitoneal drain placement after elective colorectal surgery remains widespread. Drains were not associated with earlier detection of intraperitoneal collections, but were associated with prolonged hospital stay and increased risk of surgical-site infections.Background Many surgeons routinely place intraperitoneal drains after elective colorectal surgery. However, enhanced recovery after surgery guidelines recommend against their routine use owing to a lack of clear clinical benefit. This study aimed to describe international variation in intraperitoneal drain placement and the safety of this practice. Methods COMPASS (COMPlicAted intra-abdominal collectionS after colorectal Surgery) was a prospective, international, cohort study which enrolled consecutive adults undergoing elective colorectal surgery (February to March 2020). The primary outcome was the rate of intraperitoneal drain placement. Secondary outcomes included: rate and time to diagnosis of postoperative intraperitoneal collections; rate of surgical site infections (SSIs); time to discharge; and 30-day major postoperative complications (Clavien-Dindo grade at least III). After propensity score matching, multivariable logistic regression and Cox proportional hazards regression were used to estimate the independent association of the secondary outcomes with drain placement. Results Overall, 1805 patients from 22 countries were included (798 women, 44.2 per cent; median age 67.0 years). The drain insertion rate was 51.9 per cent (937 patients). After matching, drains were not associated with reduced rates (odds ratio (OR) 1.33, 95 per cent c.i. 0.79 to 2.23; P = 0.287) or earlier detection (hazard ratio (HR) 0.87, 0.33 to 2.31; P = 0.780) of collections. Although not associated with worse major postoperative complications (OR 1.09, 0.68 to 1.75; P = 0.709), drains were associated with delayed hospital discharge (HR 0.58, 0.52 to 0.66; P < 0.001) and an increased risk of SSIs (OR 2.47, 1.50 to 4.05; P < 0.001). Conclusion Intraperitoneal drain placement after elective colorectal surgery is not associated with earlier detection of postoperative collections, but prolongs hospital stay and increases SSI risk

GROWTH-RESPONSE TO GROWTH HORMONE-RELEASING HORMONE(1-29)-NH2 COMPARED WITH GROWTH-HORMONE

To assess the growth-promoting effect of different doses of growth hormone-releasing hormone(1-29)-NH2 (GHRH(1-29)-NH2) in GH deficiency (GHD) of hypothalamic origin, 43 prepubertal children aged between 4.3 and 18.9 years (mean 10.4 +/- 2.9 years) were randomly assigned to three treatment regimens: low-dose GHRH(1-29)-NH2 (LD group; n = 15), high-dose GHRH(1-29)-NH2 (HD group; n = 12) and GH (GH group; n = 16). The LD group received GHRH(1-29)-NH2 at 30 mug/kg/day s.c. in three daily doses, the HD group received 60 mug/kg/day s.c. in three daily doses and the GH group received GH. 0.1 IU/kg/day s.c. once daily. All children were treated for a period of 6 months. Evaluation included anthropometry, bone age, intravenous and subcutaneous GHRH(1-29)-NH2 tests and determination of insulin-like growth factor I (IGF-I) levels. An increase in height velocity of 2 cm/year or more was observed in all except two children. Height velocity during treatment was lowest in the LD group, but comparable in the HD and GH groups. An increase in height SDS for bone age occurred only in the GH-treated group. GH responses to intravenous GHRH(1-29)-NH2 showed a priming effect of the LD GHRH(1-29)-NH2 treatment, while a decrease in response occurred in the GH-treated group. Following a subcutaneous test dose of one-third of the daily dose of GHRH(1-29)-NH2, GH levels remained unchanged in both the LD and HD groups. There was accumulation of GHRH immunoreactivity over time in the HD group, but there was no correlation between measured GHRH and GH levels. IGF-I levels increased in the HD and GH-treated groups. Antibodies to GHRH were detected in 54% and 58% of children in the LD and HD groups, respectively. None of these variables correlated with changes in height velocity. The results indicate that 6 months of GH and high-dose GHRH(1-29)-NH2 treatment have similar growth-promoting effects

Prevalence and Global Initiative for Chronic Obstructive Lung Disease Group Distribution of Chronic Obstructive Pulmonary Disease Detected by Preoperative Pulmonary Function Test

Despite being a major public health problem, chronic obstructive pulmonary disease (COPD) remains underdiagnosed, and only 2.4% COPD patients are aware of their disease in Korea. The objective of this study was to estimate the prevalence of COPD detected by spirometry performed as a preoperative screening test and to determine the Global Initiative for Chronic Obstructive Lung Disease (GOLD) group distribution and self-awareness of COPD.We reviewed the medical records of adults (age, ≥ 40 years) who had undergone spirometry during preoperative screening between April and August 2013 at a tertiary hospital in Korea. COPD was defined as a postbronchodilator forced expiratory volume in 1 s/forced vital capacity ratio of 40 years who had undergone spirometry as a preoperative screening test, 474 (15.6%; 404 men; median age, 70 years; range, 44-93 years) were diagnosed with COPD. Only 26 (5.5%) patients reported previous diagnosis of COPD (2.1%), emphysema (0.8%), or chronic bronchitis (2.5%). The GOLD group distribution was as follows: 63.3% in group A, 31.2% in group B, 1.7% in group C, and 3.8% in group D.The prevalence of COPD diagnosed by preoperative spirometry was 15.6%, and only 5.5% patients were aware of their disease. Approximately one-third of the COPD patients belonged to GOLD groups B, C, and D, which require regular treatment

Common surgical procedures in pilonidal sinus disease: A meta-analysis, merged data analysis, and comprehensive study on recurrence

Abstract We systematically searched available databases. We reviewed 6,143 studies published from 1833 to 2017. Reports in English, French, German, Italian, and Spanish were considered, as were publications in other languages if definitive treatment and recurrence at specific follow-up times were described in an English abstract. We assessed data in the manner of a meta-analysis of RCTs; further we assessed non-RCTs in the manner of a merged data analysis. In the RCT analysis including 11,730 patients, Limberg & Dufourmentel operations were associated with low recurrence of 0.6% (95%CI 0.3–0.9%) 12 months and 1.8% (95%CI 1.1–2.4%) respectively 24 months postoperatively. Analysing 89,583 patients from RCTs and non-RCTs, the Karydakis & Bascom approaches were associated with recurrence of only 0.2% (95%CI 0.1–0.3%) 12 months and 0.6% (95%CI 0.5–0.8%) 24 months postoperatively. Primary midline closure exhibited long-term recurrence up to 67.9% (95%CI 53.3–82.4%) 240 months post-surgery. For most procedures, only a few RCTs without long term follow up data exist, but substitute data from numerous non-RCTs are available. Recurrence in PSD is highly dependent on surgical procedure and by follow-up time; both must be considered when drawing conclusions regarding the efficacy of a procedure
