Abstract Background The optimal timing of surgery in relation to chemoradiation is still controversial. Retrospective analysis has demonstrated in the recent decades that the regression of adenocarcinoma can be slow and not complete until after several months. More recently, increasing pathologic Complete Response rates have been demonstrated to be correlated with longer time interval. The purpose of the trial is to demonstrate if delayed timing of surgery after neoadjuvant chemoradiotherapy actually affects pathologic Complete Response and reflects on disease-free survival and overall survival rather than standard timing. Methods The trial is a multicenter, prospective, randomized controlled, unblinded, parallel-group trial comparing standard and delayed surgery after neoadjuvant chemoradiotherapy for the curative treatment of rectal cancer. Three-hundred and forty patients will be randomized on an equal basis to either robotic-assisted/standard laparoscopic rectal cancer surgery after 8 weeks or robotic-assisted/standard laparoscopic rectal cancer surgery after 12 weeks. Discussion To date, it is well-know that pathologic Complete Response is associated with excellent prognosis and an overall survival of 90%. In the Lyon trial the rate of pCR or near pathologic Complete Response increased from 10.3 to 26% and in retrospective studies the increase rate was about 23–30%. These results may be explained on the relationship between radiation therapy and tumor regression: DNA damage occurs during irradiation, but cellular lysis occurs within the next weeks. Study results, whether confirmed that performing surgery after 12 weeks from neoadjuvant treatment is advantageous from a technical and oncological point of view, may change the current pathway of the treatment in those patient suffering from rectal cancer.

Spontaneous intracranial haematomas remain a challenging pathology with high morbidity and mortality (60–80% of long-term disability). Despite decades of the search for specific treatments no evidence has yet been found for neither conservative nor surgical treatment in randomized controlled studies. While patients with space occupying infratentorial haematomas are more likely to benefit from surgery treatment of supratentorial haemorrhages remains controversial. Recent studies suggest that minimally invasive surgery including endoscopy to evacuate intracranial haematoma may be more effective than conservative treatment or standard surgical craniotomy (MISTIE II). Future studies (i.e. MISTIE III, MISTICH, SWITCH) will hopefully demonstrate evidence for individualized treatments.

Abstract Introduction In the last three decades, minimally invasive surgery (MIS) has been widely used in pediatric surgery. Meta-analyses (MAs) showed that studies comparing minimally invasive with the corresponding open operations are available only for selected procedures. We evaluated all available MAs comparing MIS with the corresponding open procedure in pediatric surgery. Materials and Methods A literature search was performed on all MAs listed on PubMed. All analyses published in English, comparing pediatric minimally invasive with the corresponding open procedures, were included. End points were advantages and disadvantages of MIS. Results of 43 manuscripts were included. MAs evaluating the minimally invasive with the corresponding open procedures were available for 11 visceral, 4 urologic, and 3 thoracoscopic types of procedures. Studies included 34 randomized controlled trials. In 77% of MAs, at least one advantage of MIS was identified. The most common advantages of MIS were a shorter hospital stay in 20, a shorter time to feeding in 11, and a lower complication rate in 7 MAs. In 53% of MAs, at least one disadvantage of MIS was found. The most common disadvantages were longer operation duration in 16, a higher recurrence rate of diaphragmatic hernia in 4, and gastroesophageal reflux in 2 MAs. A lower native liver survival rate after laparoscopic Kasai-portoenterostomy was reported in one MA. Conclusion In the available MAs, the advantages of MIS seem to outnumber the disadvantages. However, for some types of procedures, MIS may have considerable disadvantages. More randomized controlled trials are required to confirm the advantage of MIS for most procedures.
