Abstract
Diverticular disease is a common finding in Western countries with an increasing prevalence with age. Many patients with the disorder remain asymptomatic. However, up to 30% of those affected may show clinical signs including pain, bleeding, obstruction, abscess, fistulae and perforation. The purpose of this chapter is to review the epidemiology, pathogenesis, clinical presentation, diagnostic regimens and treatment options for this disorder.

Abstract
Gastrointestinal bleeding in elderly individuals is a frequent cause of consultation with a physician and of hospital admissions. Co-morbidity and greater medication use in this steadily growing patient group influence the clinical course and adversely affect outcome. Clinical presentation is often predictable and guides subsequent patient management. Due to a surprising lack of prospective controlled data in the area of gastrointestinal bleeding, the selection of diagnostic and therapeutic manoeuvres often depends more on local expertise and availability than on an algorithmic approach. Advances in endoscopic, medical, radiological and surgical treatment modalities offer promising new diagnostic and therapeutic tools, particularly in concerted applications. Outcome studies on the appropriate sequence and linking of these modalities are urgently needed. This chapter will address clinical presentation, aetiology, diagnosis and treatment of both upper and lower gastrointestinal bleeding in the elderly.

Abstract
Among patients with acute gastrointestinal bleeding, older age is associated with an increased rate of comorbidity, greater medication use, and atypical clinical presentations. The aging of the population makes the evaluation and management of gastrointestinal bleeding in the elderly a special and increasingly common clinical challenge. The unique features and common causes of upper and lower gastrointestinal bleeding in the elderly are reviewed. Important management issues considered include hemodynamic resuscitation; anticoagulation; and medical, surgical, and endoscopic therapy.

Abstract
BACKGROUND Management of bleeding angiodysplasia of the gastrointestinal tract is often a major clinical problem. Lesions are frequently multiple, not detectable or missed during conventional endoscopy and patients are sometimes at high risk for complications because of advanced age and serious concomitant disorders. AIMS To determine the efficacy of a new formulation of somatostatin analogue (octreotide long-acting) in management of recurrent bleeding angiodysplasia in patients resistant to endoscopic treatment and not suitable for surgery. PATIENTS AND METHODS Three patients with recurrent bleeding angiodysplasia of gastrointestinal tract were treated with long-acting octreotide administered intramuscularly 20 mg monthly to each individual. The number of admissions for acute bleeding, hospital stay and number of blood units transfused before and after treatment (followup: 15-17 months) were regularly monitored. RESULTS In each patient, a relevant decrease in number of hospital admissions, duration of hospital stay, number of administered blood units was seen and mean haemoglobin values significantly increased in all of them after introducing long-acting octreotide therapy. CONCLUSIONS This is the first report on use of long-acting octreotide in bleeding angiodysplasia of gastrointestinal tract. Data suggest that long-acting octreotide is a safe drug and is successful in controlling recurrent gastrointestinal bleeding due to angiodysplasia in elderly patients not eligible for surgical or endoscopic therapy.

Abstract
BACKGROUND/AIM A case of angiodysplasia of the right colon presenting with a migrating site of bleeding following a segmental resection of the colon in a 38-year-old Japanese is herein reported. METHODS The case records of a patient with severe intestinal bleeding and multiple surgeries were reviewed, and then the histologic features were compared with the operative findings. The patient received many units of packed red blood cells and had also undergone three segmental colectomies and most recently a curative ileocolostomy. Despite an exhaustive evaluation, the bleeding sites could not be detected clinically. RESULTS Ectatic, tortuous submucosal veins were presented in four sections of the colon (cecum, ascending colon and transverse colon, respectively) out of a total of 30 sections that were examined. These veins pierced the proper muscle layer of the colon, but did not traverse the muscularis mucosa. Our case of segmental microscopic angiodysplasia may represent a previously unreported unique variant, because the angiodysplastic lesions were present in the segmental colon and they developed bleeding from the distal remnant colon immediately after each segmental colectomy until an extended right hemicolectomy containing the oral part of the descending colon was done. In spite of the severe bleeding, the mucosa of the colon appeared to be essentially normal during a macroscopic inspection. CONCLUSION Gastrointestinal bleeding from angiodysplasia is generally assumed to arise from macroscopically visible vascular lesions within the mucosa. However, angiodysplastic lesions are often unrecognizable and multiple in the gastrointestinal tract, and especially tend to affect both the cecum and ascending colon. When this disease process is recognized, a subtotal colectomy may thus be called for to control bleeding.

Abstract
BACKGROUND The treatment of angiodysplasia and watermelon stomach, vascular abnormalities implicated in gastrointestinal bleeding of obscure origin, is a major clinical problem. AIM To determine the efficacy of octreotide in patients with long-standing gastrointestinal bleeding due to acquired angiodysplasia and watermelon stomach, resistant to previous treatments and not suitable for surgery because of old age and/or concomitant disorders. PATIENTS AND METHODS We treated 17 patients (seven had isolated angiodysplasia, seven had multiple upper and lower gastrointestinal angiodysplasia, and three had watermelon stomach) with octreotide (0. 1 mg subcutaneous t.d.s. for 6 months). Six of the patients had liver cirrhosis, one had Glanzmann-type platelet derangement, two had cardiovascular diseases and one had chronic uraemia. RESULTS Octreotide treatment stopped bleeding in 10 patients. A transient improvement was observed in four, who needed subsequent cyclical retreatment to correct low haemoglobin levels. No effect was observed in three, probably due to the severity of the concomitant disorders. CONCLUSIONS Octreotide is a safe drug that may be useful to control the recurrent gastrointestinal bleeding due to acquired angiodysplasia and watermelon stomach, especially in patients who are not candidates for surgery due to old age and/or concomitant disorders.

Abstract
BACKGROUND Colon vascular ectasias are a common cause of lower intestinal bleeding among the elderly. The lesions may be difficult to diagnose at colonoscopy because they are small and their appearance may be influenced by the patient's blood pressure, blood volume, and narcotic sedation during the procedure. The purpose of this study was to determine whether naloxone influenced the appearance of colon vascular ectasias at colonoscopy. METHODS One hundred forty-four patients older than 60 years undergoing complete colonoscopy participated in the study. Medications were given in the usual doses. After a 2-minute inspection of the cecum and ascending colon, naloxone was given, followed by another 2-minute observation period. Photographic documentation of areas of interest was obtained before and after administration of naloxone. RESULTS One hundred fourteen patients (79%) had no ectasias before or after administration of naloxone. Fourteen (9.7%) initially had normal vessels, and the vessels became more prominent; 4 (2.7%) initially had no ectasias, but ectasias later developed. Four patients (2.7%) had ectasias before administration of naloxone that did not change; 8 (5.4%) had ectasias before administration of naloxone that increased in size (3 patients), number (7 patients), or both (2 patients). CONCLUSIONS Naloxone can enhance the appearance of normal colonic vasculature and ectasias. Naloxone is an important adjunctive medication for patients undergoing examinations for lower intestinal bleeding.

Abstract
An eight-year-old, sexually intact, male, 37 kg crossbred dog was referred for investigation of two acute episodes of intestinal bleeding and severe anaemia within a five-month period. There was no evidence of coagulopathy or underlying systemic disease. Technetium-labelled red blood cell scintigraphy suggested the colon as the site of bleeding. Colonoscopy identified a focal area of dilated and tortuous mucosal blood vessels. Histopathology of the resected colon revealed vascular ectasia (angiodysplasia). At nine months post-resection, the dog remained healthy and free of any overt intestinal haemorrhage.

Abstract
PURPOSE To evaluate the safety and efficiency of microcoil embolization in upper and lower gastrointestinal hemorrhage. PATIENTS AND METHODS Superselective microcoil embolization was performed in 10 patients (upper gastrointestinal bleeding, n = 3; lower gastrointestinal bleeding, n = 7) who had acute gastrointestinal hemorrhage. Embolization was performed as peripherally as possible with use of coaxial catheter systems. Embolization materials included microcoils (2-4 mm) alone (n = 5), microcoils and polyvinyl alcohol particles (355-500 microm) (n = 4), and microcoils and gelatin sponge particles (n = 1). RESULTS Immediate hemostasis was achieved in eight patients. In two patients with dual blood supply of the bleeding site, significant reduction of hemorrhage resulted. In these two patients, it was technically impossible to place the coaxial catheter distally enough to allow safe embolization of both feeding vessels. No clinical signs of ischemia or infarction were observed after intervention. CONCLUSION Microcoil embolization is a safe and efficient procedure for controlling acute lower gastrointestinal bleeding if performed in a superselective catheter position. In upper gastrointestinal bleeding, microcoil embolization is an established treatment and can be performed more proximally.

Abstract
PURPOSE Selective mesenteric angiography is an expensive, invasive, diagnostic, and therapeutic tool for lower gastrointestinal hemorrhage. Some institutions have required a positive nuclear medicine bleeding scan before angiography. We have attempted to determine if this is a valid screening test for mesenteric angiography. Are there any other factors to predict which patients are actively bleeding and who will benefit from angiography? METHODS All cases of mesenteric angiography for hemorrhage performed during a 12-year period were reviewed. RESULTS A total of 131 angiograms were performed during a 12-year period with 45 patients demonstrating active bleeding; 54 patients had a bleeding scan before angiography. A positive bleeding scan did not increase the percentage of positive angiograms. A history of prior gastrointestinal bleeding, transfusions, orthostatic hypotension, or tachycardia were not predictors for a positive angiogram. DISCUSSION This study could not identify any single useful predictor that will increase the likelihood of obtaining a positive angiogram. Nuclear medicine scans should not be used routinely as a screening test for angiography.

Abstract
BACKGROUND Lower gastrointestinal bleeding can be a confusing clinical conundrum, the satisfactory evaluation and management of which requires a disciplined and orderly approach. Diagnosis and management has evolved with the development of new technology such as selective mesenteric angiography and colonoscopy. PURPOSE This study was undertaken to review the available data in the literature and to determine the current optimum method of evaluation and management of lower gastrointestinal hemorrhage most likely to result in a successful outcome. METHODS Data available on the topic of lower gastrointestinal bleeding in the English literature were obtained via MEDLINE search and were reviewed and analyzed. RESULTS The colonic origin of lower gastrointestinal hemorrhage in order of decreasing incidence is diverticulosis, inflammatory bowel disease, including ischemic and infectious colitis, colonic neoplasia, benign anorectal disease, and arteriovenous malformations. Approximately 10 to 15 percent of all cases of rectal bleeding are attributable to a cause that is proximal to the ligament of Treitz. Small intestinal sources such as arteriovenous malformations, diverticula, and neoplasia account for between 3 and 5 percent of all cases. Colonoscopy successfully identified an origin in severe hematochezia in 74 to 82 percent of cases. Mesenteric angiography has a sensitivity of 42 to 86 percent. The best method of management depends on whether hemorrhage persists, the severity of continued hemorrhage, the cumulative transfusion requirement, and the specific origin of bleeding. CONCLUSION Lower gastrointestinal hemorrhage is a complex clinical problem that requires disciplined and sophisticated evaluation for successful management. Diverticulosis is the most common cause. Colonoscopy is the diagnostic procedure of choice both for its accuracy in localization and its therapeutic capability. Selective mesenteric angiography should be reserved for those patients in whom colonoscopy is not practical. Precise identification of the bleeding source is crucial for a successful outcome. Specific directed therapy, such as segmental colonic resection for bleeding diverticulosis, is associated with the highest success rate and the lowest morbidity. A complete review of lower gastrointestinal bleeding is contained herein.

Abstract
Acute massive hematochezia provides one of the greatest diagnostic and therapeutic challenges to the physician. Although most patients stop bleeding spontaneously and further evaluation can be carried on with less urgency, 10% to 15% require urgent diagnostic and therapeutic procedures. Clearly, the least invasive effective solution to the bleeding problem is generally the best, although in some cases, emergency undirected surgery may be necessary. Subtotal colectomy can be done with acceptable morbidity and mortality in this situation, provided that the surgeon is confident of a colonic source of the bleeding. An understanding of the strategies outlined above encourages the management of such patients with an eye to maximizing therapeutic benefit while minimizing morbidity.

Abstract
BACKGROUND Major colonic haemorrhage poses difficult diagnostic and therapeutic problems and, in contrast to upper gastrointestinal bleeding, has no generally accepted plan of management. METHODS We report community-based prospective data accumulated over 2 years (1991-93) on 1602 patients referred to an open-access bleeding unit with suspected gastrointestinal haemorrhage. RESULTS Of 278 (17%) admissions with suspected lower GI haemorrhage, 252 were confirmed. Forty-eight per cent were defined as "significant' bleeds, with a decrease in haemoglobin and cardiovascular compromise. Of 102 significant bleeds in subjects more than 60 years old, 29% rebled, and 12.6% required emergency surgery. Diverticular disease (24%) was the commonest diagnosis, with tumours, infective colitis, and inflammatory colitis each at 10%. The overall 30-day mortality for colonic bleeding was 5.1% (13 of 252), with only 1 death occurring in the group less than 60 years old. CONCLUSIONS This study provides a unique database for the natural history of colonic bleeding and its management within the setting of a specialized bleeding unit.

Abstract
Lower GI bleeding can be slow and chronic or massive and fatal. ED evaluation of these patients begins with history directed at determining the severity and amount of bleeding, and eliciting symptoms of volume depletion. Physical examination determines orthostasis, exclusion of an upper GI source for bleeding, and rectal examination. Laboratory evaluation is directed at determining baseline status of hemoglobin/hematocrit and platelet adequacy, as well as assessing concomitant medical problems. Although many of these patients are elderly, resuscitation is vigorous and should not be deterred by other medical problems. Differential diagnosis can be broad in the ED, but the vast majority of bleeding is caused by diverticulosis or angiodysplasia. Diagnostic capabilities are limited in the ED, but our skill at stabilization and resuscitation has helped decrease morbidity and mortality in acute lower GI bleeding.

Abstract
PURPOSE This study was undertaken to clarify the importance of bleeding vascular ectasia of the colon as the etiology of massive lower gastrointestinal hemorrhage in patients 40 years of age or younger. METHODS An otherwise healthy 21-year-old male was admitted to a tertiary medical center with massive lower gastrointestinal hemorrhage. Technetium-labeled red blood cell scan, selective visceral angiography, and colonoscopy identified the source of bleeding as vascular abnormality of the descending colon. Segmental colonic resection was performed. RESULTS Histologic review of the specimen demonstrated a vascular ectasia. The patient recovered uneventfully and has had no further stigmata of hemorrhage. A review of the literature was undertaken to make clear the significance of vascular ectasia as the source for massive colonic hemorrhage in the young adult. CONCLUSION This is the first report that documents histologically a vascular ectasia as the source of massive lower gastrointestinal hemorrhage in an otherwise healthy patient less than 40 years of age. Vascular ectasia is an uncommon cause of lower gastrointestinal hemorrhage in the young adult.

Abstract
BACKGROUND Gastrointestinal bleeding is a common diagnostic problem. We describe here a 42-year-old woman who had iron deficiency anemia that went undiagnosed for 8 years. SYMPTOMS AND RESULTS She had a 'blood spray' when crouching, backache, and abdominal pain attacks during sexual intercourse. Defecography, but neither clinical examination nor endoscopy, demonstrated abnormal mobility of the rectal mucosa associated with other pelvic floor abnormalities. THERAPY After rectopexy, the bleeding stopped, and the blood values normalized.

Abstract
PURPOSE Elderly patients frequently develop lower gastro-intestinal bleeding secondary to diverticulosis. This select group of patients potentially tolerates blood loss poorly, often have coexisting cardiovascular morbidity, and may not tolerate surgical intervention. Thus, optimal management of elderly patients with diverticular hemorrhage remains difficult. METHODS All patients who were admitted with the diagnosis of diverticulosis at the St. Louis University affiliated hospitals during the past 60 months were identified. Those with diverticular bleeding were extracted. Patients were reviewed as to age, sex, diagnosis of diverticular bleeding, number of bleeding episodes, lowest hemoglobin before transfusion, amount of blood received, treatment, operations, the presence of recurrent bleeding, morbidity, and mortality. RESULTS One hundred fifteen consecutive patients, age 70 years admitted with lower gastrointestinal hemorrhage secondary to diverticulosis who required transfusion, were identified. Mean age was 79 years; 26 of 115 (23 percent) were more than 80 years of age; 78 of 115 (54 percent) were males; 39 of 115 (34 percent) had more than one previous admission for diverticular hemorrhage. The mean serum hemoglobin was 8.9 g/dl. All patients underwent colonoscopy; 34 of 115 (29 percent) underwent 99Tc scanning, of which 18 of 34 (54 percent) underwent arteriogram. Seven of 18 (39 percent) demonstrated extravasation secondary to bleeding diverticulosis. The mean transfusion requirement was 2.8 (range, 1-17) units; 21 of 115 (18 percent) required intestinal resection; 2 of 21 (9 percent) experienced a 30-day mortality. Among those, 94 of 115 were treated without surgery, and 3 of 94 (4 percent) died. Mortality was independent of initial hemoglobin (P = 0.21), previous diverticular hemorrhage (P = 0.44), amount of blood transfused (P = 0.36), and type of treatment (0.09). CONCLUSIONS Most diverticular bleeding in the elderly is well tolerated using nonoperative management. Success and safety of treatment does not seem to depend on a history of previous diverticular bleeding, initial hemoglobin, or amount of blood transfused. The majority of patients are treated nonoperatively. Surgical intervention seems to be well tolerated.

Abstract
Lower gastrointestinal hemorrhage is a common clinical problem for which multiple diagnostic tests and therapeutic interventions have been developed but no optimal approach has been established. We reviewed 107 consecutive patients admitted to the Massachusetts General Hospital for management of acute lower gastrointestinal hemorrhage to determine the effectiveness of diagnostic and management technologies, with particular attention to urgent colonoscopy. Colonoscopy yielded a diagnosis in 90% of patients, provided the opportunity for successful therapy in 9 of 13 patients (69%), and shortened hospital stay. Angiography performed after a scan positive for bleeding was often diagnostic, and angiography provided the means for successful therapy in 5 of 10 patients (50%). Barium enema and sigmoidoscopy had lower clinical yields. Although roles exist for other technologies, colonoscopy is the most convenient and effective first test in the evaluation of patients with significant lower gastrointestinal hemorrhage. Diagnostic yield, therapeutic opportunity, and cost effectiveness are maximized in early studies.

Abstract
Arteriovenous malformation (AVM) of the stomach is extremely rare. We report a patient with asymptomatic gastric AVM detected during mass screening of the upper gastrointestinal tract. The patient, a 69-year-old female, had no history of gastrointestinal bleeding. Endoscopy revealed a gastric submucosal tumor (3 cm in diameter) at the posterior wall below the esophago-cardiac junction. Endoscopic ultrasonography (EUS) showed a hypoechoic structure in the third layer of the stomach, suggesting gastric AVM in the submucosal layer. Complete resection of the AVM tissue was performed by strip biopsy with surgical resection. Histological examination showed AVM in the submucosal layer. EUS examination was useful for the diagnosis of gastric AVM in this case.

Abstract
We have reviewed the clinical details and radiology of all patients with non-variceal gastrointestinal haemorrhage referred for angiography during an 8 year period. Forty-six patients with a history of overt bleeding had 49 technically satisfactory angiograms of which 29 were true positives but 16 were false negatives (sensitivity 64%, accuracy 63%). The accuracy of angiography in this group was much higher (92%) in those patients referred within 24 h of admission. Nine patients who had a history of iron-deficiency anaemia due to sub-acute blood loss had 9 angiograms. Five studies in this group were correct (two true negatives and three true positives) but there were four false positive studies. Angiography is an effective means of diagnosis in patients with acute gastrointestinal haemorrhage who have a negative endoscopy but best results will only be achieved when the study is performed with minimal delay following negative endoscopy. Angiography should also be considered in patients with continuing subacute blood loss when other investigations are negative.

Abstract
The advent of fiberoptic endoscopy, which became widespread in the evaluation of gastrointestinal bleeding throughout the late 1970s and 1980s, has dramatically changed both our understanding of the extent to which vascular malformations account for gastrointestinal blood loss and our ability to treat these lesions at the time of diagnosis. Colonic vascular malformations appear to be the single most common cause of acute or recurrent gastrointestinal bleeding episodes in patients over 60 years of age, being responsible for the bleeding in as many as 35% of such patients. Although less common as a cause of upper gastrointestinal bleeding, these lesions still account for 2% to 5% of bleeding lesions in older patients. Diagnosis is accomplished by endoscopy, and the vascular malformations can then be coagulated via the endoscope using one of a number of thermal systems. The argon laser, the heater probe, and the BICAP system are all effective and safe throughout the gastrointestinal tract, especially in the cecum and right colon, where the majority of sporadic vascular malformations occur. Monopolar cautery and the Nd:YAG laser are equally efficacious, but their greater and less predictable depth of coagulation make them much less safe in the cecum and right colon. There are no apparent advantages in terms of efficacy and safety between laser treatment and the other thermal modalities. The laser has the advantage of being quicker, which is especially important when treating large or multiple lesions. The other modalities have the advantages of portability and low relative cost. Endoscopic therapy with lasers or other thermal devices is nonspecific. The effects are achieved by thermally coagulating the mucosal vascular lesions, allowing the coagulated tissue to slough, and leaving a mucosal ulceration that subsequently heals with re-epithelialization. Endoscopic coagulation has thus been reported effective in the treatment of gastrointestinal mucosal vascular lesions regardless of their etiology or characteristics. It has been effective for sporadic vascular malformations, hereditary hemorrhagic telangiectasia (Osler-Weber-Rendu disease), radiation proctocolitis, the blue rubber-bleb nevus syndrome, and diffuse gastric antral vascular ectasia (the watermelon stomach). As we move through the 1990s and beyond, these endoscopic modalities offer an effective, relatively safe, and clearly less invasive treatment option for the many patients who experience acute, recurrent, or chronic gastrointestinal bleeding from any of these lesions.

Abstract
In a retrospective analysis the diagnostic procedure was evaluated in patients with acute lower gastrointestinal bleeding. Bleeding sources were localized distally to the ligament of Treitz in 233 patients (1979-1988). Patients with hemorrhoidal bleeding were not included. Following exclusion of an upper gastrointestinal bleeding the diagnostic procedure was initiated with a recto-/colonoscopy. Lesions were detected in 77% of the treated patients (n = 136). Angiography localized the bleeding in 68%, in combination with colonoscopy the identification of the bleeding source reached 86.5% in the treated patients. Following scintigraphy the bleeding source was determined in 89.7% of these patients. The sensitivity of colonoscopy (0.93) was superior to the angiography (0.78) and to the scintigraphy (0.75). Apart from neoplasms and adenomas angiodysplasia and Meckel's diverticula were the most common sources of the bleeding in patients who underwent operation. In 61 patients endoscopic therapy was performed, however, 6.5% of these patients had to be operated on later because of persistent bleeding. All together 79 patients underwent operation, 31 for bleeding and 48 for other reasons. 12 patients died, 6 of them were operated on for the bleeding, the other for neoplasms.

Abstract
In the past 9 years, we have operated on 56 patients with gastrointestinal bleeding of obscure origin. Selective visceral angiography demonstrated the bleeding lesions in 24 of the 30 patients who underwent this investigation. Six of these 24 patients, however, had a negative angiogram initially and the lesions were only demonstrated on a repeat angiogram. The negative initial angiograms were due to: (1) slow bleeding from lesions in two patients; (2) a small bleeding tumour that caused only intermittent jejunojejunal intussusception in one patient; (3) technical fault in one patient; and (4) spasm of the bleeding vascular lesions and their feeding arteries in two patients. We advocate repeat angiography the following day in all patients in whom profuse bleeding continues, and during the next intestinal bleeding in those whose bleeding stops after the initial negative angiography. In patients who have repeated episodes of massive bleeding, and in whom full investigations fail to reveal the bleeding source, repeat angiography carried out 4 weeks after the bleeding has stopped can sometimes demonstrate the vascular lesions.

Abstract
Although most often clinically silent, colonic diverticula are responsible for a large number of gastrointestinal illnesses in our society. Complications of diverticular disease, including perforation and hemorrhage, may occur in 15% to 20% of patients with diverticula during their lifetime, and although often mild and self-limiting diseases, they too frequently cause life-threatening problems that require prompt surgical intervention. Despite a cadre of sophisticated laboratory and radiologic tests that have been developed to aid in the diagnosis of complicated diverticular disease, the diagnosis and treatment of diverticulitis still relies heavily on patient history, physical examination, physician judgment, and the patient's clinical response to treatment. Thus it is important for the managing physician to fully understand the pathogenesis of diverticula, the clinical consequences and modes of presentation of complicated diverticular disease, and the array of interventions available for treatment of these problems. This monograph summarizes our knowledge of diverticular disease to date and tries to give specific guidelines for the treatment of patients with complicated diverticulitis. However, it must be understood that the presentation and severity of these complications vary widely from patient to patient. Thus one cannot take a single approach toward a patient who has diverticulitis or diverticular bleeding. Rather, successful outcomes depend on an individual approach to each patient while maintaining certain generally accepted principles of treatment.

Abstract
Sixty-eight patients with massive lower gastrointestinal (G.I.) hemorrhage underwent emergency arteriography. Patients were transfused an average of six units of packed red blood cells within 24 hours of admission. The bleeding source was localized arteriographically in 27 (40%), with a sensitivity of 65% among patients requiring emergency resection. However, twelve of the 41 patients with a negative arteriogram still required emergency intestinal resection for continued hemorrhage. Radionuclide bleeding scans had a sensitivity of 86%. The right colon was the most common site of bleeding (35%). Diverticulosis and arteriovenous malformation were the most common etiologies. Selective intra-arterial infusion of vasopressin and embolization were successful in 36% of cases in which they were employed and contributed to fatality in two patients. Twenty-three patients underwent segmental resection, whereas seven patients required subtotal colectomy for multiple bleeding sites or negative studies in the face continued hemorrhage. Intraoperative infusion of methylene blue via angiographic catheters allowed successful localization and resection of bleeding small bowel segments in three patients. Overall mortality was 21%. The mortality for patients without a malignancy, with a positive preoperative arteriogram, and emergency segmental resection was 13%.

Abstract
Early classification of lower gastrointestinal bleeding as occult, minor overt, or major overt allows a practical approach to evaluation and management. Localization of the bleeding site is the next step. In occult and minor overt bleeding, the cause can usually be determined from results of conventional diagnostic tests; however, angiography and even intraoperative endoscopy may be necessary in some particularly difficult cases. In contrast, major overt bleeding may only allow time for angiographic localization before surgery. Using this approach, the primary care physician can successfully manage most patients with lower gastrointestinal bleeding.

Abstract
Previous studies have demonstrated that brief pulses of selectively absorbed optical radiation can be used to confine thermal injury to pigmented targets within tissues. We performed studies in rabbits to assess the usefulness of this technique for selectively coagulating the colonic vasculature. By measuring the optical absorbance of rabbit colon with a spectrophotometer, it was determined that hemoglobin exhibits strong absorption relative to the rabbit colon at a wavelength of 577 nm. Because light must be absorbed to affect tissue, it was hypothesized that laser pulses of this wavelength would selectively damage blood vessels. This hypothesis was tested by examining the effect of 300-microseconds-long 577-nm laser pulses on rabbit colon in vivo. For delivered radiant exposures between 4 and 8 J/cm2, selective coagulation of the colonic vasculature could be produced without damage to the surrounding colon. At greater radiant exposures, vessel hemorrhage was occasionally noted but no transmural thermal injury was produced with delivered radiant exposures as high as 22 J/cm2. This technique may form the basis of a safe and simple treatment of vascular lesions of the colon such as angiodysplasia.

Abstract
Major colonic haemorrhage remains a difficult diagnostic and therapeutic problem. We propose that those patients who continue to bleed after resuscitation are best served by immediate laparotomy. High flow antegrade irrigation and intra-operative colonoscopy can then be used to localize the site of bleeding and allow appropriate excisional surgery rather than blind colonic resection.

Abstract
Of 34 patients with massive lower intestinal bleeding, 17 (11 men and 6 women, age range 33-85 years; mean 64.8 years) were diagnosed as having angiodysplasia of the colon. The diagnosis was made by colonoscopy and the lesions were treated successfully by fulguration in 13 (86.6 per cent) of 15 patients. Two of the 17 patients underwent surgical resection of the involved intestinal segment. One patient still has sporadic intestinal haemorrhage, and another patient died from bleeding of the left colon after blind right colectomy. The remaining 13 patients have had no further bleeding in the 1-7 years following colonoscopic fulguration. Colonoscopy is a useful method of diagnosing angiodysplasia of the colon and affords the possibility of treatment.

Abstract
The authors reviewed their experience with diagnosis and treatment of lower gastrointestinal bleeding secondary to colonic arteriovenous malformations (AVM). A diagnosis was established exclusively by endoscopy in 80 percent of the patients. Twenty-eight patients were treated by endoscopic coagulation; bleeding stopped after one or more treatments in 67.9 percent of these patients. There were no complications or mortality as a consequence of endoscopic treatment. Surgery controlled the recurrent bleeding in six of seven cases of failed endoscopic coagulation, and in 13 of 17 cases where surgery only was undertaken, for an overall success rate 79.2 percent. It is concluded that colonoscopy can accurately establish the diagnosis of colonic AVMs in chronic lower gastrointestinal bleeding. Endoscopic coagulation is a useful adjunct in the treatment of this condition, and is safe, effective, and leaves other options open.

Abstract
Other than gastrointestinal bleeding, there are few clinical emergencies the successful management of which is so dependent on the setting of priorities. Sequential attention to resuscitation, localization, specific diagnosis, and definitive therapy at a pace proportional to the rate of blood loss results in a satisfactory outcome in most patients who present with lower gastrointestinal bleeding.

Abstract
Colorectal perforation per se requires surgical intervention whereas in lower gastrointestinal bleeding localisation of the bleeding point has priority to any therapeutic action. Among the prevailing diagnostic methods coloscopy was found to be clinically most relevant. In profuse bleeding or for the interval detection of angiodysplasia angiography is the means of first choice. Subtotal colectomy has proved advantageous, if resection is necessitated without localisation of the bleeding site. The present operative concept in colonic perforation implies the primary excision of the lesion in diverticular as well as in neoplastic disease.

Abstract
Fifty patients with massive lower gastrointestinal bleeding were initially managed with emergency angiography. The average age was 67.2; mean hematocrit, 23.7; and average transfusion, 7.6 units. Thirty-six patients (72%) had bleeding site located; bleeding sites were distributed throughout the colon. Etiologies of bleeding included diverticular disease (19 patients) and arteriovenous malformations (15 patients). Twenty of 22 (91%) patients receiving selective intra-arterial vasopressin stopped bleeding; however, 50% rebled on cessation of vasopressin. Thirty-five of 50 (70%) patients underwent surgery, with 57% operated on electively after vasopressin therapy. Seventeen patients had segmental colectomy, with no rebleeding. Nine of the 17 patients had diverticular disease in the remaining colon. Operative morbidity in these 35 patients was significantly improved when compared to previously reported patients undergoing emergency subtotal colectomy without angiography (8.6% vs. 37%) (p less than 0.02). Emergency angiography successfully locates the bleeding site, allowing for segmental colectomy. Vasopressin infusion transiently halts bleeding, permitting elective surgery in many instances.
