1/455. The pattern of intestinal obstruction in malaysia.

    This is a review of 261 patients operated for 271 instances of mechanical intestinal obstruction over a 5-year period in a developing country in the tropics. The pattern of intestinal obstruction in Chinese is similar to that in Caucasians, where adhesions account for the largest number of cases. The occurrence in Malays, Indians, Pakistanis and Ceylonese is similar to that in other developing communities where external hernia is commonest while adhesive or tumour obstruction is rare; however, these racial groups do not exhibit the high incidence of intussusception and volvulus found in africa and india. The operative mortality was 13-9 per cent, which is comparable to that in Western series. The major adverse factors in intestinal obstruction, i.e. extremes of age, associated disease, gangrenous bowel, large bowel obstruction and malignancy, were confirmed. Fluid and electrolyte imbalance was frequent, as in other tropical series, but with intensive preoperative correction it was not an important adverse factor.

2/455. Gallstone ileus with impaction at the neck of a Meckel's diverticulum.

    We report a case of gallstone ileus in which the stone impacted at the neck of a Meckel's diverticulum. CT demonstrated the gallstone as a calcified mass in the lower abdomen. Gallstone ileus was diagnosed although a more accurate diagnosis was not obtained pre-operatively. The site of impaction was not typical and a blind loop filled with contrast materials was evident. We believe that this is the first report demonstrating this rare condition with imaging.

3/455. Renal fibrohistiocytic sarcoma. Three cases and a review of the literature.

    The purpose of this paper is to report three unpublished cases of so-called "renal malignant fibrous histiocytoma" which should be more appropriately called "renal fibrohistiocytic sarcoma", and to review and analyze the data concerning 41 cases collected from the literature and our three new cases, making a total of 44 cases. Our third case is very interesting; in addition to the fact that this condition is rare, this particular patient also had concomitant nonmalignant ascites and compression of the descending colon, both conditions being rarely associated with renal cancer. The average age of the patients was 58 years; in 66% of the cases the tumor involved the left kidney; 57% of the patients were males; the average tumor size was 12 cm; nephrectomy was performed in 93% of the cases; the average survival was 16 months. In none of the cases was a preoperative diagnosis correctly made. It is concluded that a triad of symptoms and signs (renal pain, weight loss, and large tumor size) as well as a triad of imaging characteristics (areas of low density on the CT scan, hypoechoic areas on ultrasound, and hypovascularity on angiography) may hold the promise of a preoperative diagnosis. It is suggested that the tumor arises from the system of Gerota's fascia-renal capsule.

4/455. Preoperative sonographic diagnosis of midgut malrotation with volvulus in adults: the "whirlpool" sign.

    Midgut malrotation and volvulus, found mostly in children, are rare and difficult to diagnose preoperatively in adults. We report 2 cases in which a 68-year-old man and a 75-year-old woman presented with intermittent cramping abdominal pain, abdominal distention, and vomiting. Abdominal sonography demonstrated wrapping of the superior mesenteric vein and bowel loops around the superior mesenteric artery (the "whirlpool sign") in both patients. Abdominal CT revealed similar findings. The diagnoses of midgut volvulus and mesenteric malrotation were made, and the patients underwent laparotomy. The man was confirmed to have duodenojejunal malrotation and volvulus, and the woman had cecal volvulus. The whirlpool sign is valuable for the preoperative diagnosis of mesenteric vessel malrotation and midgut volvulus.

5/455. ileus with incarceration of Spigelian hernia.

    An 85 year-old female with ileus due to incarceration of Spigelian hernia, which was diagnosed pre-operatively with the findings of the abdominal computed tomography and plain radiographic pictures, is reported. A simple hernioplasty was made by suturing the internal oblique and transverse muscles to the rectus sheath. The post-operative condition is satisfactory without any recurrence of hernia.

6/455. carcinoid tumor of the ileum with intestinal obstruction.

    An 83 year-old female presenting with intestinal obstruction due to a carcinoid tumor of the small intestine is herein reported. The intra-operative findings revealed a stenotic lesion and ischemic changes of the ileum. A segmental jejunotomy was performed and a submucosal tumor was recognized as a causal lesion. Histopathological investigation demonstrated the features of carcinoid tumor.

7/455. A case of intestinal obstruction following stent graft placement for an abdominal aortic aneurysm.

    A 76-year-old male was admitted to hospital complaining of severe abdominal pain, constipation, nausea and vomiting. The patient had undergone stent graft placement of an abdominal aortic aneurysm (AAA) at another hospital 13 months prior to admission. An X-ray, computed tomography scan and barium-enema examination revealed partial obstruction of the duodenum. Stent graft placement has been reported to be a useful procedure for AAA. However, as mass effects associated with AAA cannot be excluded, several symptoms may remain postoperatively.

8/455. Small bowel obstruction secondary to herniation through a 5-mm laparoscopic trocar site following laparoscopic lymphadenectomy.

    Incisional hernias occur in <1% of women undergoing operative laparoscopy and are mostly limited to trocar sites > or =10 mm. This is a report of a 54-year-old woman with endometrial cancer who presented with nausea, vomiting and abdominal pain 1 week following laparoscopically-assisted vaginal hysterectomy, bilateral salpingo-oophorectomy, and lymphadenectomy. Abdominal radiographs and computed tomography demonstrated small bowel obstruction and herniation through a 5-mm trocar site. Reduction of the hernia and closure of the fascial incision were performed at exploratory laparotomy with normal recovery. Bowel herniation can occur through 5-mm trocar sites following prolonged operative laparoscopy. The peritoneum and fascia of these incisions should be closed.

9/455. Volvulus of the ileum in adult diagnosed pre-operatively by helical 3-dimensioned computed-tomography.

    A 46 year-old male who was strictly diagnosed as having volvulus of the ileum based on the pre-operative information brought by computed tomography (CT) and helical (spiral) 3-dimensioned computed tomography was surgically treated. The post-operative course was satisfactory and the patient is now under observation without any exacerbation of symptoms one year after surgery.

10/455. Progressive perinatal bowel obstruction--a rare cause of short-bowel syndrome.

    A girl was born after an uneventful pregnancy of 36 weeks. Prenatally, distended bowel loops had been seen on ultrasound. Multiple small-bowel atresia was diagnosed and treated surgically. In the course of the next eleven weeks, previously patent segments of small bowel became obstructed. In 4 separate operative sessions, several segments of jejunum and ileum were resected, leaving 23 cm of ileum with the ileocecal valve in place. On microscopic examination of all resected material, necrosis of the mucosa was found consistent with ischemia. The child survived and tolerated full enteral feeding at the age of 8.5 months. The origin of the progressive obliterating process remains unknown.
