[Smart, Social, and Mobile: the future of Nephrology in the Era of Digital Health]. / Smart, Social e Mobile: la Nefrologia nell'era della Sanità digitale.

Healthcare is in the middle of a digital revolution. Physicians are adopting mobile apps that make them more effective and patients are taking to ones that give them more control over their healthcare. Mobile technology is changing Medicine. A new movement for free open access medical education (FOAMed) is growing through Social Media. E-learning is increasing access to new and exciting learning opportunities, deeply changing the traditional concept of continuous medical education. What will be the future of Nephrology in the era of Digital Health?

Video-assisted versus open ileocolic resection in primary Crohn's disease: a comparative case-matched study.

Despite the technical difficulties, laparoscopic ileocolic resection for Crohn's disease (CD) has become widely accepted in recent years, due to its potential benefits. There are numerous reports concerning the use of laparoscopy in successfully treating CD, including two randomized trials and few comparative studies. For the most part, these reports outline use of laparoscopic approach in primary distal ileal or ileocolic disease, with a careful selection of the patients. The purpose of this comparative case-control study was to point out potential advantages and disadvantages in short- and long-term outcomes of the laparoscopic approach compared with the open one. From January 1999 to January 2004, 200 patients were admitted in our Surgical Unit for complicated primary CD. 100 patients (group 1) underwent a laparoscopic ileocolic resection, 100 patients (group 2), with alike demographic and clinical characteristics, underwent the same procedure using a traditional approach. The incidence of perforative disease was 32 and 40% in groups 1 and 2, respectively. Average operative time was 140 min (range 90-245 min) in the video-assisted group and 98 min (range 65-255 min) in group 2 (P < 0.05). Postoperative morbidity was 6 and 8% in groups 1 and 2, respectively (P = NS). Recovery of peristalsis occurred within 2-3 days in group 1 and 3-4 days in group 2 (P = NS). Median postoperative hospitalization was 7 days (range 5-18 days) in group 1 and 9 days (range 7-22 days) in control group (P < 0.05). The overall rate of surgical relapse of CD was 8 and 13% in groups 1 and 2, respectively (P = NS), at a mean follow-up of 52 and 60 months, respectively. The 1-year surgical recurrence rate was similar (3%) for the two groups. In conclusions, in spite of the technical difficulties, video-assisted surgery for CD offers advantages over laparotomy, including less postoperative pain, reduced postoperative hospital stay, less disability of the patient, and better cosmetic results. Potential advantages are: easier approach for re-resection, lower rate of postoperative adhesions and bowel obstruction, and lower rate of wound complications.

[Role of anastomotic configuration in ileocolic resection for Crohn's disease]. / Ruolo della configurazione anastomotica nella resezione ileocolica per malattia di Crohn.

Crohn's disease is characterised by a high incidence of perianastomotic recurrence after ileocolic resection. The influence of the anastomotic configuration on the incidence of reoperation was evaluated in patients undergoing resection for Crohn's disease. In our Institution, from 1993 to 2007, 308 consecutive patients affected by ileocolic Crohn's disease were submitted to 343 ileocolic resections or right colectomies. In 292 cases (85.1%), an antiperistaltic side-to-side (or functional end-to-end) anastomosis was performed, with an 80 mm linear stapler in 190 cases, a 100 mm linear stapler in 79, and a hand-sewn anastomosis in 23. The other hand-sewn anastomotic configurations were: 30 (8.8%) side-to-side isoperistaltic, 15 (4.3%) end-to-side and 6 (1.8%) end-to-end. The overall morbidity was 7.3%, with two postoperative deaths (0.6%) with no significant differences between groups. There were 38 overall recurrences (11%). In the side-to-side antiperistaltic group, the rate of recurrence was 8.2%, significantly lower than the recurrence rates observed in the other anastomoses (26.9%, p = 0.002), especially side-to-side isoperistaltic anastomosis (33.3%, p = 0.001). Early recurrences (< 1-year) were 2.6%, without significant differences between groups. There was a higher trend for end-to-end anastomosis (16.6%). In the side-to-side antiperistaltic group the morbidity was higher in the large mechanical anastomoses (100 mm length), but the recurrence rate was lower in this group as compared to the 80 mm anastomoses (1.2% vs. 12.1%, p = 0.006). Our non-randomised study suggests a better trend for the wide side-to-side antiperistaltic technique in terms of recurrence rate. These observations need further investigation with randomised controlled trials to compare the different anastomotic procedures.

Postoperative chemoradiotherapy in rectal cancer. Long-term results of a pilot study.

It has recently been proven that postoperative radiotherapy combined with fluorouracil affords an increase in survival and local control in patients with rectal cancer. However, haematological and intestinal toxicity also increase. Experimental and clinical studies have shown an increased effect of radiation with an acceptable toxicity by delivering the drug via continuous intravenous infusion. From 1988 to 1998, 80 patients radically operated on for stage B2-C rectal cancer were irradiated with 3 fractions of 100 cGy per day up to a total dose of 5,600 cGy; 34 of these patients underwent postoperative radiotherapy alone and 46 received radiotherapy combined with concomitant protracted infusion of fluorouracil at doses of 250 mg/m2 per day. After a median follow-up of 60 months, the 5-year overall and disease-free survival rates were 59% and 54%, respectively, in the combined modality group, as compared to 42% and 34%, respectively, in the radiation alone group. The differences were non-significant, but the incidence of local relapse and patient survival showed better trends with the combined approach. The international literature data are in favour of a combined approach in both the preoperative and postoperative treatment of advanced rectal cancer. Adjuvant therapy needs to be re-assessed in trials using total mesorectal excision as the standard operative technique.
