Laparoscopy is useful in the management of a wide range of benign conditions. In the elective situation, it may be chosen to evaluate hepatobiliary disorders, abdominal masses, or chronic pain, and is an ideal way to sample tissue. Under the emergency setting, it is another tool for the assessment of trauma patients and may be of value in those patients with abdominal pain, mesenteric ischemia, fever of unknown origin, or gastrointestinal hemorrhage. It is important for the surgeon to be familiar with the technique, correctly prepare the patient, and be aware of the risks and limitations of this diagnostic modality.

Small bowel volvulus is an uncommon but important cause of small intestinal obstruction. It often results in ischemia or even infarction. Delay in diagnosis and surgical intervention increases morbidity and mortality rates. Based on cause, small bowel volvulus can be divided into primary and secondary type. Goals for treatment of small bowel volvulus should include physician awareness of this uncommon diagnosis, accurate workup, and advanced surgical intervention. The presentation and subsequent management of 35 patients with small bowel volvulus confirmed by laparotomy are reviewed and discussed. The incidence of small bowel volvulus in the adult European and North American is low. The resultant mortality rate, however, makes diagnosis critically important. The cardinal presenting symptom is abdominal pain. There is no single specific diagnostic clinical sign or abnormality in laboratory or radiologic finding. In practice, the diagnosis can only be made by laparotomy. The failure to perform an exploratory laparotomy cannot be justified. Early diagnosis and early surgery are the keys for successful management of strangulation obstruction of the small bowel.

A 76-year-old woman with lumbo-abdominal pain as a chief complaint went through a series of examinations including ultrasonography, CT, and angiography, the final diagnosis being aneurysm of the splenic artery congenitally arising from the superior mesenteric artery (SMA). Since the SMA had to be clamped during the excision of the aneurysm, a biballoon intraluminal shunting was utilized to avoid the visceral ischemia. The splenic artery distal to the aneurysm then underwent end-to-side anastomosis to the SMA. This shunting procedure was considered convenient and applicable to other similar situations in the vascular surgery.

Myxedema megacolon is rare; usually, it manifests with abdominal distention, flatulence, and constipation. Herein we describe a 72-year-old man who had intermittent diarrhea, bloating, and abdominal pain for more than a year. Cultures of stool specimens for Clostridium difficile enterotoxin were variably positive and negative. Colonoscopic biopsy specimens were thought to be consistent with chronic ischemia. Thyroid function tests showed severe hypothyroidism; the patient's symptoms resolved with thyroid hormone replacement. We hypothesize that gross dilatation of the colon, attributed to myxedema, was followed by intestinal ischemia and complicated by recurrent episodes of pseudomembranous colitis. A review of the relevant literature is provided. This unusual manifestation of myxedema should be considered in the differential diagnosis when a patient has diarrhea, bloating, and abdominal pain.

A 45-yr-old female with mild chronic systemic lupus erythematosus for 20 yr, and with a stroke, digital infarction, and transient vocal cord paralysis during those 20 yr, had severe abdominal pain for 2 wk due to omental infarction associated with the presence of anticardiolipin antibodies. This report suggests that patients with otherwise mild systemic lupus erythematosus may develop severe recurrent thromboembolic events associated with anticardiolipin antibodies, that anticardiolipin antibodies may be associated with mesenteric ischemia, and that mesenteric ischemia associated with anticardiolipin antibodies should be considered in the differential of significant, unexplained abdominal pain in patients with systemic lupus erythematosus.

In 12 of 264 children treated with enterocystoplasty 15 spontaneous perforations occurred. Of the 12 children 9 had myelodysplasia. All segments of the gastrointestinal tract were used for the augmentation and most were detubularized. Surgery to increase bladder outlet resistance was done in 8 cases. At the time of each perforation 9 children had sterile cultures, however, 3 died of overwhelming sepsis. Presenting signs included abdominal pain in 8 cases, septic shock in 4 cases and shoulder pain in 4 older myelodysplastic children with diaphragmatic irritation from escaping urine. Cystography demonstrated a leak in 10 of 11 cases. Urodynamic studies revealed good compliance with low maximum filling pressure in 8 of 10 children. Hyperreflexia was noted in only 5 cases and outlet resistance greater than 85 cm. water was demonstrated in 5. Histological analysis showed changes in the bowel wall consistent with ischemia but suture granulomas were present in areas adjacent to the perforation site or thinned areas in biopsy or autopsy specimens. In addition to the theory that overdistention may cause enterocystoplasty perforation, current detubularization techniques may produce areas of relative ischemia, which become accentuated when the augmented bladder is distended beyond a reasonable volume.

An 85-year-old male with a sudden onset of abdominal pain was operated on under the suspicion of intestinal ischemia and was later diagnosed as acute superior mesenteric venous thrombosis (SMVT). The patient was successfully treated by resecting the entire involved bowel and performing a double ileostomy. These procedures are considered to be the preferred method of choice for improving survival in poor risk patients.

Vascular reconstruction for chronic intestinal ischemia can be accomplished by endarterectomy or aortomesenteric bypass. In our practice, antegrade bypasses from the supraceliac aorta to the celiac axis and superior mesenteric artery are currently the most frequently used techniques. Such reconstructions often use multiple or bifurcated large diameter vascular prostheses and have demonstrated excellent long-term patency. Despite these salutory results, we have noted an unusual perioperative response in three of these patients, which is the subject of this report. All three patients underwent uncomplicated elective mesenteric revascularization with grafts (diameter greater than or equal to 6 mm) originating in the supraceliac aorta. Indications for operation included (1) history of postprandial pain, (2) documentation of weight loss, and (3) angiographic evidence of advanced atherosclerotic disease with appropriate collateral development. Episodes of abdominal pain occurred 5 to 20 days after operation when normal food intake was reinstituted. In two patients immediate angiograms revealed patent grafts with diffuse mesenteric vasospasm. Treatment with intravenous hyperalimentation and nifedipine for 10 days resulted in complete resolution of symptoms. In the third patient, symptoms were totally relieved by temporary reduction in oral intake and administration of nifedipine. A later angiogram revealed a patent graft. All patients have remained asymptomatic and regained normal weight. This pattern of postrevascularization pain has not been seen in our patients undergoing revascularization with small (i.e., venous) conduits originating in the infrarenal aorta. The cause appears to be a heightened myogenic response of a "protected" vascular bed when suddenly exposed to the high perfusion pressure and blood flow of large caliber antegrade conduits. Prophylaxis with calcium channel blockers and use of smaller diameter grafts (5 mm) may avoid this disturbing syndrome.

The age and advanced stage of atherosclerosis in this patient population require careful preoperative evaluation and attention to detail in the perioperative period in an effort to avoid complications in other organ systems resulting from diffuse occlusive disease. The keys to accurate diagnosis and successful management of patients with acute or chronic mesenteric ischemia include a detailed history, focusing on the quality and temporal relation of the symptoms; an accurate vascular assessment on physical examination, with attention directed to ruling out nonvascular causes of the symptoms; a high index of suspicion of vascular origin for otherwise unexplainable abdominal pain in the patient population at risk; an aggressive diagnostic approach with a low threshold for obtaining mesenteric angiography; CT of the abdomen to rule out occult pancreatic carcinoma; expeditious correction of metabolic and electrolyte abnormalities and optimization of cardiac function; and early surgical intervention, with directed revascularization in an effort to minimize loss of bowel from infarction.

A 5-year-old male with right atrial myxoma without interatrial communication who presented with abdominal pain, vomiting, fever, and guaiac positive stool is reported. He was later found to have ischemia of a jejunal segment necessitating segmental resection. Although his symptoms persisted postoperatively, surgical removal of a right atrial myxoma was followed by complete resolution of his intestinal symptoms. We demonstrated that the mesenteric vasculitis was of nonembolic origin, and we speculate autoimmune arteritis as a possible mechanism.
