Randomized Controlled TrialModified lay-open (incision, curettage, partial lateral wall excision and marsupialization) versus total excision with primary closure in the treatment of chronic sacrococcygeal pilonidal sinus: a prospective, randomized clinical trial with a complete two-year follow-up.
The best surgical technique for treating pilonidal sinus disease is controversial. The aim of this study is to compare the modified lay-open technique with primary closure following excision with respect to operating time, healing time, time before return to work, morbidity rate, and recurrence rate. ⋯ The results of the present study suggest that modified lay-open is superior to excision with primary closure for the surgical treatment of chronic sacrococcygeal pilonidal sinus with regard to morbidity and recurrence rates, and time before return to work, although healing time is longer.

Comparative StudyTumour regression grading in the evaluation of tumour response after different preoperative radiotherapy treatments for rectal carcinoma.
Preoperative radiotherapy (PRT) for rectal carcinoma has been shown to cause tumour regression and increase local control and patient survival. The aim of this study was to examine the usefulness of tumour regression grading (TRG) in quantifying the effect of PRT. ⋯ Tumour regression grading offers detailed information of the effect of PRT and shows that tumour regression is more marked after long-term chemoradiation than after short-course radiotherapy (p=0.02). In contrast, T-stage downstaging was similar in both groups and did not correlate with the TRG results (p=0.05).
