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 authors report their endoscopic experience in the treatment of intestinal inflammatory complications and their prevention with cyclic antibiotic treatment (rifaximin 400 mg b.i.d. for 7 days/month), followed by recolonizing treatment with lactobacilli (2 capsules in the morning for 7 days/month), for an overall period of 12 months. In all 79 cases (45 males and 34 females, mean age 63 years, range 55-75 years), the treatment proved capable of controlling the symptoms and averting the onset of the complications which follow attacks of acute diverticulitis. These complications include uncontrollable sepsis, free perforation of a hollow viscus, evolutive fistulation, intestinal occlusion, abscesses not drained percutaneously, all factors which necessitate urgent elective surgery. Rifaximin, together with lactobacillus treatment, proved to be effective, well-tolerated and safe, and can thus be considered an indispensable aid in the treatment of diverticular disease and in the prevention of its complications.

The results of 37 consecutive cases of Hartmann's procedure over a 5-year period (1985-1990) were reviewed. The series consisted of 27 emergency procedures (11 diverticular disease, 13 carcinoma, two trauma and one sigmoid volvulus) and ten elective procedures (nine carcinoma and one peridiverticular abscess). The indications for emergency procedures were obstruction and perforation. All patients presented with faecal peritonitis owing to colonic perforation. The mean (range) age was 79.4 (34-90) years. The postoperative mortality rate was 30 per cent overall (11 of 37), 33 per cent (four of 12) in the diverticulitis group, 23 per cent (five of 22) in the carcinoma group, and 100 per cent in the iatrogenic trauma group. Death was mainly due to sepsis (82 per cent). Postoperative complications were mainly wound infections, which occurred in 43 per cent (16 of 37) cases. In 25 per cent of the surviving patients, re-establishment of continuity was performed in three of 17 (18 per cent) of the carcinoma group and three of seven (43 per cent) of the diverticulitis group. No attempt at restoration of intestinal continuity was made in six cases due to medical risk in two, extensive carcinoma in two and local recurrence with metastatic disease in two. Three patients refused all further intervention. There were no postoperative deaths after the restoration of continuity. This series reflects the severity of the pathology in this high risk group of patients. However, the operation can be life-saving for a selected group of patients and offers good palliation for advanced colorectal tumours.

Retroperitoneal perforation of diverticular disease is very uncommon and can be difficult to diagnose because of possible pathways of communication between the retroperitoneal space and the thigh. An iliopsoas abscess from a ruptured diverticulum may drain into the hip joint if the capsule has been violated. Cases of abscesses or gas in the thigh have been reported in which thigh pain was the predominant symptom, overshadowing any abdominal signs. We report a case in which hip sepsis due to a ruptured diverticulum was the presenting feature.

Diverticular disease is most common in the sigmoid colon. Its etiology is multifactorial and probably related to low-fiber diets, age dependent changes of the colonic wall, hypermotility and myochosis with subsequent increase in intraluminal pressure. Acute diverticulitis results from inflammation of a pseudo-diverticulum. It can progress to pericolitis and perforation with abscess formation. Therapy of uncomplicated diverticulitis is a conservative regimen with bowel rest and intravenous broad spectrum antibiotics. In subjects with complicated diverticulitis, preoperative percutaneous image-guided catheter drainage of diverticular macroabscesses is indicated. This aims at resolving intra-abdominal sepsis thereby avoiding the need for temporary colostomy and multiple-stage surgery. Interval single stage sigmoid resection with primary anastomosis should then be performed. Generalized peritonitis, with or without evidence of free perforation, should be treated surgically. Long-term cereal fiber supplementation and physical activity may prevent complications and inflammatory recurrences in diverticular disease.

In this work the authors describe the different stages of diverticulosis and analyze the pathogenetic principal factors. During the period from 1979 to 1998 they observed 420 patients affected by diverticular disease (224 M; 196 F), 42 (10%) of them were operated on for complications. Fifteen patients operated on in elective time underwent a one stage procedure of resection and anastomosis with derivative colostomy; 27 patients were operated on in emergency: 6 patients had one stage procedure of resection and anastomosis with derivative colostomy, 16 patients Hartmann's procedure, 3 patients Mikulicz's procedure and 2 patients colostomy and peritoneal drainage. Two patients died from septic shock. There was absence of postoperative complications for the patients operated on in elective time, while 8 cases (29.6%) showed peritoneal sepsis and 4 cases (14.8%) infection of wound in the patients operated on in emergency. The Authors describe the different surgical options in the treatment of colonic complicated diverticular disease and conclude that the surgical treatment is not definite. A tendency is to make a one-stage procedure of resection and anastomosis and to reduce the Hartmann's procedure or the simple colostomy with drainage of abdominal cavity.

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.

Inflammatory complications of diverticular disease are still responsible for high mortality rates. The aim of the present study was to analyse the factors that primarily influence the type of treatment and prognosis of such pathologies. From 1996 to 2006, 88 patients were admitted to our department for inflammatory complications secondary to diverticular disease. The majority of the patients were emergency room referrals, and nearly half of them were elderly (over 65 years of age). The most frequently observed complications were acute diverticulitis (45.5%), which was almost always resolved with medical therapy, and diverticular perforations (43.2%), for which surgical therapy was always necessary. The main treatment for localised peritonitis was one-stage colorectal resection, whereas for generalized peritonitis a two-stage resection was the procedure of choice. The highest degrees of peritonitis were observed in elderly patients. Restoration of bowel continuity was performed in nearly all patients below 65 years of age, but was not possible in 44.4% of those aged above 65. Postoperative mortality occurred in two cases, both with diffuse peritonitis, advanced age, and elevated anaesthetic risk. The present series seems to confirm the findings of other Authors, namely that the prognosis of diverticular perforation is influenced more by patient-related factors (older age, sepsis, comorbidity) than by the type of surgical procedure. Thus, it is probable that a decrease in the mortality rate and improvements in the quality of life can be achieved through more aggressive diagnostic protocols and new preventive strategies.

The further development of multidetector row CT (MDCT) has led to changes in the application and examination technique, leading to a need to justify the level and frequency of radiation exposure associated with MDCT. A literature review of how the use of modern scanners has affected diagnosis was undertaken, followed by a year-long retrospective study of MDCT scans of patients presenting with symptoms of abdominal sepsis. The diagnostic accuracy of detecting causes of abdominal sepsis using this technology was sought. Scans were performed using a LightSpeed 16 system (GE Healthcare Medical Systems, Slough, UK and Milwaukee, WI). Clinical diagnoses were based upon surgical and histopathological findings, treatment outcome and follow-up scans. System dose parameters recorded were the dose-length product (DLP) and volume CT dose index. The literature on investigating suspected abdominal sepsis has not been updated significantly since the time of conventional CT. 94 patients were included in the study; causes of abdominal sepsis could be detected with a sensitivity of 0.95 and a specificity of 0.91. Repeat examination and cumulative exposure was a key finding. Patients with abscesses and acute pancreatitis had the highest number of scanner visits; patients with diverticular disease had the lowest number of visits, lowest cumulative DLP and shortest stay in hospital. Cumulative DLP was affected by scan length, number of scans and patient size. In conclusion, diagnostic accuracy data for MDCT scans using 16 slices confirm that CT remains a suitable modality for imaging abdominal sepsis but scope for dose constraint exists.

Pyogenic-liver abscesses are due to bacteria mostly from the portal and biliary tracts. There is usually only one located in the right liver, but they may be found in the left liver, be multiple or multilocular. Diagnosis, based on ultrasound and/or computed tomography scan, is confirmed by percutaneous-needle aspiration to identify the bacteria causing the disease. Global management includes the treatment of sepsis and the aetiology of the liver abscess: biliary lithiasis, diverticular disease, colon cancer, appendicitis or other intra-abdominal infections. However, no cause is found in 20% of cases. Treatment is based on antibiotics and, sometimes, percutaneous drainage while the cause may be treated immediately or later if the sepsis is controlled. Interventional radiology is often used. Surgery may be performed in case of failure of initial treatment and to cure the cause of the abscess. Prognosis may be poor, especially if there are associated-risk factors, such as diabetes and immunodepression, even though the outcome has improved with a multidisciplinary approach.
