In this session different issues for the surgical management of diverticular disease DD) were considered. The first session debated about the antibiotic treatment for acute uncomplicated diverticulitis (AUD), and supports their use selectively rather than routinely in patients with AUD. The second session discussed the best surgical treatment for those patients. Open approach is a valid choice especially in acute setting, while the laparoscopic approach should be individualised according to the level of skills of the surgeon and the risk factors of the patient (such as obesity and state of health at the time of the operation). The third session debated about the peritoneal lavage and drainage, which is still a safe surgical procedure. However, it requires longer follow-up and results of other trials to draw an adequate conclusion. The last session covers the current surgical certainties in managing complicated DD: 1. urgent colectomy has higher mortality in immune-compromised patients, while in elective surgery is comparable with other populations; 2. laparoscopic peritoneal lavage (LPL) should be the choice in young/fit patients; 3. elective resection is safer in an inflammation free interval; 4. laparoscopic resection shows advantages in several outcomes (such as post-operative morbidity and lower stoma and re-operation rate); 5. in Hinchey III/fecal peritonitis, primary sigmoid resection and anastomosis (open or laparoscopic) could be proposed in young/ fit patient; 6. in case of emergency surgery, Hartmann procedure (open or laparoscopic) must be considered in critically ill/unstable patient.
