Massive hemorrhage from diverticular disease of the colon is a very difficult problem in abdominal emergency surgery. The pathogenesis of bleeding colonic diverticulosis is strictly correlated to the angioarchitecture of the colonic diverticular wall. Here the vasa recta penetrate the colonic wall from the serosa to the submucosa through connective tissue septa. Injurious factors arising from the colonic or diverticular lumen can produce an eccentric damage to the luminal side with intimal thickening, segmental weakening of the artery and its rupture with massive bleeding. Conventional barium enema is not able to show the source of the hemorrhage in the majority of the bleeding patients; colonoscopy, as primary emergency procedure, has significant positive findings in 41.5%-83.7% of patients. Radionuclide bleeding scans have a sensitivity rate of 86%-94%. Emergency arteriography localizes the bleeding source in higher rates ranging from 58% to 86% and is successful after intraarterial infusion of vasopressin or embolization in 47%-92% of patients. Surgical treatment for continued bleeding from diverticular disease is controversy. Segmental resection should be performed on patients with localized bleeding sources (positive arteriogram). Laparotomy, anterograde irrigation and intraoperative colonoscopy are indicated in patients with multiple bleeding sites and negative arteriography. Because the right colon is the most common site of bleeding in same cases is necessary to perform a subtotal colectomy with ileorectal anastomosis. Blind resections particularly in the elderly patients present high rebleeding rate (> 60%) and high mortality (30%) with sepsis accounting for the majority of deaths.

The most frequent complications in diverticular disease are local abscess, perforation with peritoneal sepsis, fistula and ileus. Extraabdominal manifestation is an actual rarity. A haematogenous bacterial spread via portal vein with formation of liver abscess has seldom been described. But a complicated diverticular disease as a cause for a brain abscess is an absolute rarity. Our case presents a patient with brain abscess caused by asymptomatic, retroperitoneal perforated colonic diverticulosis. We discuss diagnostic steps both in diverticular disease and brain abscess and different surgical options in the treatment of colonic complicated diverticular disease.

Diverticulosis of the colon is a common condition of increasing age. Complications of diverticulitis including stricture, perforation and fistula formation often require surgery. Perforated diverticulitis may rarely present with spreading superficial sepsis. We describe for the first time, to our knowledge, a case of retroperitoneal diverticula perforation presenting as necrotising fasciitis of the leg necessitating hind-quarter amputation.

Diverticular disease of the colon (DDC) includes a spectrum of conditions from asymptomatic diverticulosis to symptomatic uncomplicated diverticulosis, segmental colitis associated with diverticulosis, and acute diverticulitis without or with complications that may have serious consequences. Clinical and scientific interest in DDC is increasing because of the rising incidence of all conditions within the DDC spectrum, a better, although still limited understanding of the pathogenic mechanisms involved; the increasing socioeconomic burden; and the new therapeutic options being tested. The goals of treatment in DDC are symptom and inflammation relief and preventing disease progression or recurrence. The basis for preventing disease progression remains a high-fiber diet and physical exercise, although evidence is poor. Other current strategies do not meet expectations or lack a solid mechanistic foundation; these strategies include modulation of gut microbiota or dysbiosis with rifaximin or probiotics, or using mesalazine for low-grade inflammation in uncomplicated symptomatic diverticulosis. Most acute diverticulitis is uncomplicated, and the trend is to avoid hospitalization and unnecessary antibiotic therapy, but patients with comorbidities, sepsis, or immunodeficiency should receive broad spectrum and appropriate antibiotics. Complicated acute diverticulitis may require interventional radiology or surgery, although the best surgical approach (open versus laparoscopic) remains a matter of discussion. Prevention of acute diverticulitis recurrence remains undefined, as do therapeutic strategies. Mesalazine with or without probiotics has failed to prevent diverticulitis recurrence, whereas new studies are needed to validate preliminary positive results with rifaximin. Surgery is another option, but the number of acute events cannot guide this indication. We need to identify risk factors and disease progression or recurrence mechanisms to implement appropriate preventive strategies.

Although the true prevalence is unknown, colonic diverticulosis is one of the most common disease of the digestive tract in Western countries. Based on administrative data of hospitalized patients, the incidence of diverticulitis has been increasing in last decades. In general, elderly patients undergo less frequently an elective colonic resection; but a substantial part of emergency surgeries is performed in elderly patients. In these older patients the choice of any clinical and surgical option is to be correlated not only to the severity of diverticulitis, but also to general status and the co-existing comorbidities. In this regard, it is mandatory that all patients undergo a multidimensional, comprehensive geriatric assessment to correctly identify those who are fit, vulnerable or frail. The analysis of data currently available highlights three relevant elements: type and severity of peritoneal contamination, hemodynamic conditions (stable or unstable), and concomitant comorbidities (fit or frail status). There is no single ideal surgical treatment that can be considered as gold standard for all clinical presentations; the final clinical decision-making should always be based on patient's general health status, severity of peritonitis and of sepsis. In a septic elderly patient who is hemodynamically unstable, treatment should be as prompt as possible independent of the Hinchey's stage, and could include either a Mickulicz stoma or a DCS strategy. In an elderly patient who is fit and hemodynamically stable, the surgical options are similar to those in a younger patient. If a patient is frail but hemodynamically stable, he should be treated with a Hartmann's procedures.
