Purpose: This study compared the short- and long-term clinical outcomes of laser hemorrhoidoplasty (LH) vs. conventional hemorrhoidectomy (CH) in patients with grade II/III hemorrhoids. Methods: PubMed/Medline and the Cochrane Library were searched for randomized and nonrandomized studies comparing LH against CH in grade II/III hemorrhoids. The primary outcomes included postoperative use of analgesia, postoperative morbidity (bleeding, urinary retention, pain, thrombosis), and time of return to work/daily activities. Results: Nine studies totaling 661 patients (LH, 336 and CH, 325) were included. The LH group had shorter operative time (P<0.001) and less intraoperative blood loss (P<0.001). Postoperative pain was lower in the LH group, with lower postoperative day 1 (mean difference [MD], –2.09; 95% confidence interval [CI], –3.44 to –0.75; P=0.002) and postoperative day 7 (MD, –3.94; 95% CI, –6.36 to –1.52; P=0.001) visual analogue scores and use of analgesia (risk ratio [RR], 0.59; 95% CI, 0.42–0.81; P=0.001). The risk of postoperative bleeding was also lower in the LH group (RR, 0.18; 95% CI, 0.12– 0.28; P<0.001), with a quicker return to work or daily activities (P=0.002). The 12-month risks of bleeding (P>0.999) and prolapse (P=0.240), and the likelihood of complete resolution at 12 months, were similar (P=0.240). Conclusion LH offers more favorable short-term clinical outcomes than CH, with reduced morbidity and pain and earlier return to work or daily activities. Medium-term symptom recurrence at 12 months was similar. Our results should be verified in future well-designed trials with larger samples.

Purpose: Prehabilitation (PH) is purported to improve patients’ preoperative functional status. This systematic review and meta-analysis sought to compare short-term postoperative outcomes between patients who underwent a protocolized PH program and the existing standard of care among colorectal cancer patients awaiting surgery. Methods: A search in MEDLINE/PubMed, the Cochrane Library, Embase, Scopus, and CINAHL was conducted to identify relevant articles. Repetitive and exhaustive combinations of MeSH search terms (“prehabilitation,” “colorectal cancer,” “colon cancer,” and “rectal cancer”) were used to identify randomized and nonrandomized studies comparing PH versus standard of care for colorectal cancer patients awaiting surgery. The primary outcomes included postoperative morbidity, length of hospital stay, and readmission rates. Results: Seven studies including 1,042 colorectal cancer patients (PH, 382) were included. No significant differences were found in intraoperative outcomes. The postoperative complication rates were comparable between groups (Clavien-Dindo grades I and II: risk ratio, 0.82; 95% confidence interval, 0.62–1.07; P=0.15; Clavien-Dindo grades ≥III: risk ratio, 1.02; 95% confidence interval, 0.72–1.44; P=0.92). There were also no significant differences in length of hospital stay (P=0.21) or the risk of 30-day readmission (P=0.68). Conclusion Although PH does not appear to improve short-term postoperative outcomes following colorectal cancer surgery, the quality of evidence is impaired by the limited trials and heterogeneity. Thus, further large-scale trials are warranted to draw definitive conclusions and establish the long-term effects of PH.

PURPOSE: Childhood acute immune thrombocytopenic purpura (ITP) is a benign hematologic disease. Therapy does not affect the natural history of the illness. We evaluated the clinical and laboratory findings, treatment and prognosis of childhood acute ITP in Korea through a retrospective multicenter study. METHODS: We analyzed retrospectively the data of 1, 829 children with acute ITP through survey of 33 hospitals among 43 hospitals in Korea from Sep. 1992 to Aug. 2001. RESULTS: Male to female ratio was 1.3: 1 and the median age at the diagnosis of ITP was 2.9 (0.1 17) years. Median duration of follow up was 6 months. One hundred and forty nine cases of the total 1, 829 patients (8.1%) received no treatment. The initial median platelet count of the non-treated group was 42, 500/mm3. Among the 861 cases who were followed up over 6 months, 315 cases (36.6%) progressed into chronic ITP. Associated with this high rate of chronicity of childhood acute ITP patients in Korea, we must consider the fact that acute ITP patients with fast improvement in the first episode tend not to follow up. Considering that fact, the rate of chronicity becomes 17.2% of the 1, 829 acute ITP patients. The treated group used many kinds of treatment methods. Intravenous immunoglobulins (IVIG) with or without prednisolone (PD) (67.5%) were the most commonly used regimens. In the group treated with IVIG alone, the platelet count began to rise above 50, 000/mm3 at 2.6 days, 100, 000/mm3 at 3.7 days and 150, 000/mm3 at 4.9 days. Four hundred and twenty two cases of the 1, 686 (25.0%) cases followed up after first episode of ITP relapsed. The relapse rate was significantly higher in older patients and in girls than in younger patients and in boys (P< 0.05). The chronicity of ITP statistically increased with age (P< 0.05) and that was the only valuable factor. CONCLUSION: Despite the fact that childhood acute ITP is a pretty common disaese, there is no agreement on the best treatment method for this disease. The establishment of Korean treatment guideline of childhood acute ITP, based on an analysis of multicenters, seems to be needed.
