RESUMEN
BACKGROUND: There is currently a paucity of research comparing the clinical outcomes of single-incision laparoscopic colectomy (SILC) with those obtained with multiport laparoscopic colectomy (MLC). This meta-analysis aimed to examine whether SILC shows real benefits over MLC, especially in terms of feasibility, safety, and oncological adequacy. METHODS: A literature review of studies comparing SILC and MLC has been performed which looked at the following outcomes: mortality, morbidity, and oncological parameters of adequacy, as well as other potential benefits and drawbacks. Standardized mean difference for continuous variables and odds ratios for qualitative variables were calculated. RESULTS: Thirty studies comparing SILC and MLC were reviewed: two prospective randomized clinical trials (RCTs), eight prospective studies, and 20 retrospective comparative observational studies. Overall, in a cohort of 3502 patients who underwent surgery, SILC was used in 1068 cases (30.5 %) and MLC was used in 2434 cases (69.5 %). Mean intraoperative blood loss was significantly lower when the SILC procedure had been used (75.06 vs. 91.45 ml, P = 0.03); bowel function recovered significantly earlier in the SILC patients (1.96 vs. 2.15 days, P = 0.03); mean postoperative hospital stay was significantly shorter in the SILC group (5.55 vs. 6.60 days, P = 0.0005); and length of skin incision was significantly shorter in SILC patients (3.98 vs. 5.28 cm, P = 0.01). However, in the latter four outcomes, evidence of heterogeneity was found. In contrast, MLC showed significantly better results when compared to SILC in terms of distal free margins (12.26 vs. 10.98 cm, P = 0.01). CONCLUSIONS: SILC could be considered as a safe and feasible alternative to MLC in experienced hands. Further evidence for this surgical procedure should be assessed in the form of high-quality RCTs, with additional focus on its use in low rectal cancer resection.

BACKGROUND: Evidence on the biological behavior and clinical courses of minimally invasive and widely invasive follicular thyroid carcinoma (MI-FTC, WI-FTC) is still debatable. The current study was conducted to identify differences between MI and WI tumors and those prognostic parameters influencing late outcome such as local recurrence and survival. METHODS: From January 1998 to October 2013, 71 patients were operated on in our department because of a FTC. A retrospective cohort study was carried out to compare 42 MI-FTC and 29 WI-FTC. The comparison involved evaluation of patient characteristics, tumor characteristics, tumor staging, and risk assessment. RESULTS: A diameter greater than 4.0 cm, the presence of vascular invasion, the TNM stage III-IVA, and the high risk at AMES system risk stratification were independent factors significantly related to the presence of a WI-FTC. The only independent predictor of recurrence and disease-free survival at 10-year follow-up was a tumor size greater than 4.0 cm. CONCLUSIONS: More attention must be paid in the postoperative tumor re-staging of those patients with tumor size larger than 4.0 cm, which was the only parameter predicting recurrence and influencing disease-free survival. Nevertheless, definitive recommendations cannot be made without a longer follow-up.

AIM: Diverticulitis free perforation still remains a major life-threatening condition. Herein we evaluate factors influencing prognosis of patients with perforated colonic diverticulitis and the current validity of Mannheim Peritonitis Index (MPI) in predicting mortality. MATERIAL OF STUDY: From January 2000 to October 2010, 39 patients were operated on for generalized peritonitis from perforated diverticulitis RESULTS: Five postoperative deaths (12.8%) related to septic shock occurred. A cross-sectional study between deceased and non-deceased patients was carried out. Deceased patients were significantly older than non-deceased (76.4 vs. 59.1 years,p=0.019); duration of symptoms was longer in deceased patients (102 vs. 26.9 hours, p=0.000); MPI was higher in deceased patients (31.4 vs. 21.2, p=0.000). Age, duration of symptoms and MPI were independent risk factors predicting poor prognosis. The highest sensitivity and specificity of MPI in predicting mortality was shown for a score higher than 27. CONCLUSIONS: MPI is still effective in predicting postoperative mortality. People who nurse older persons must pay higher attention to complaints in order to reduce the delay in hospitalization.
