In order to verify the safety of an ideal length of hospital stay (5-6 days) after open colectomy, we reviewed complications after 371 consecutive, elective colorectal resections for cancer at our institution between April 1991 and December 1998. Specifically, age of the patient, length of hospital stay and when the complication was diagnosed were registered. The median postoperative hospital stay was 9 days (range, 4-34 days). No difference in length of hospital stay was detected in patients < or = 65 years old versus > 65 years old (P = NS). All major complications (anastomotic leak, intestinal bleeding, intestinal occlusion, pneumonia, pulmonary embolism, pulmonary edema, stroke, angina pectoris, and fascial dehiscence) were diagnosed before the fifth postoperative day (P < 0.05). Among the minor complications (vomiting, packed red blood cells transfusion, diarrhea, wound infection, urinary tract infection, and pleural effusion), none requiring hospitalization was detected later then 5 days after the operation. We conclude that postoperative length of stay after colorectal resection for cancer can be reduced safely to five to six days after the operation.

Venous and arterial thromboembolism constitutes a significant cause of morbidity and mortality in patients with inflammatory bowel disease. The most common thrombotic manifestations are lower extremity deep vein thromboses with or without pulmonary embolism. Occasionally, thromboembolic events occur in the main abdominal vessels, such as the portal and superior mesenteric veins, vena cava and hepatic vein, aorta, splanchnic and iliac arteries, or in the limb arteries. The decision-making process for the treatment of these uncommon thromboembolic complications in inflammatory bowel disease may be very challenging for several reasons: 1) no standardized therapies are available; 2) the decision of starting anticoagulant therapy implies the potential risk of intestinal bleeding; 3) thromboembolic events may recur and be life-threatening if inadequately treated. The literature was searched by using MEDLINE, Embase, and the Cochrane library database. Studies published between 1970 and 2007 were reviewed. We discuss the medical and surgical therapeutic options that should be considered to optimize the outcome and reduce the risk of complications in abdominal thromboembolisms associated with inflammatory bowel disease.

Venous and arterial thromboembolism are both serious extraintestinal manifestations of inflammatory bowel disease (IBD). Acquired risk factors seem to play a more prominent role than congenital in promoting thrombotic events. Prevention of thromboembolism is thus mainly aimed at minimizing the acquired/reversible risk factors (e.g., inflammation, immobility, hospitalization, steroid therapy, central intravenous catheters, smoking, oral contraceptives, and deficiency of B vitamins and folate). The diagnosis of venous and arterial thromboembolism is extremely challenging and requires a high degree of vigilance. Deep vein thrombosis and pulmonary embolism may be clinically silent or manifest with only few specific symptoms. Thrombosis of the portal vein system may occur with nonspecific symptoms such as abdominal pain, nausea/vomiting, abdominal tenderness, ascites, and fever. The diagnosis of arterial thromboembolism may also be challenging, particularly when the splanchnic region is involved. Indeed, arterial thrombosis of the splanchnic region tends to be overlooked and misinterpreted as a clinical exacerbation of IBD. Early diagnosis plays a central role in optimizing the therapeutic intervention and reducing the risk of short-term and long-term thrombosis-associated complications. The decision regarding the duration of systemic anticoagulation must take into account the individual risk of intestinal bleeding.

Hookworm infections are rare causes of acute gastrointestinal bleeding. We report a middle aged man with primary nephrotic syndrome and pulmonary embolism. During the treatment with steroids and anticoagulants, the patient presented acute massive hemorrhage of the gastrointestinal tract. The results of gastroscopy showed red worms in the duodenum. Colonoscopy and CT angiogram of abdomen were unremarkable. Capsule endoscopy revealed fresh blood and multiple hookworms in the jejunum and ileum. Hookworms caused the acute intestinal bleeding. The patient responded well to albendazole. Hematochezia was markedly ameliorated after eliminating the parasites. Hence, hookworm infection should be considered in the differential diagnosis of a patient with obscure gastrointestinal bleeding. Capsule endoscopy may offer a better means of diagnosis for intestinal hookworm infections.
