PURPOSE: This study was designed to analyze the short-term clinical and functional outcomes of perineal rectosigmoidectomy with levatoroplasty for complete rectal prolapse. METHODS: The data were prospectively collected and consisted of the clinical data, the functional status before and after surgery, the operation record, and the postoperative course. The functional status was evaluated by using Wexner's constipation score (0-30), Wexner's incontinence score (0-20), anorectal manometry, and pudendal nerve terminal motor latency. Follow-up was performed at 3-6 months after the operation by using both a standardized questionnaire completed in the outpatient clinic or telephone interview (n=23) and an anorectal physiology test (n=7). RESULTS: During a one-year period, 23 patients (male=10) underwent perineal rectosigmoidectomy with levatoroplasty for complete rectal prolapse. The median duration of the operations was 88 minutes. The median length of postoperative hospital stay was 6 days. There was one urinary tract infection and no mortalities. The constipation score was significantly decreased after the operation (9.8 vs 3.8; P<0.001), and constipation was improved in 90 percent (19/21) of the cases. The incontinence score was significantly decreased after surgery (mean preop.=11.6, postop.=3.7; P<0.001) and incontinence was improved in 17 of 21 patients with impaired continence (81 percent). Anal sphincter function was not improved but rectal reservoir capacity was significantly decreased after surgery (rectal urgent volume (45.7 cc vs 37.1 cc; P=0.045), maximal tolerable volume (120 cc vs 85.7; P=0.011). Most patients (83 percent) felt that the operation had improved their symptoms. The major reasons for dissatisfaction after surgery were frequent defecation, fecal soiling, persistent or aggravated fecal incontinence, and recurrence. One patient had a complete recurrence (4.3 percent), and another patient had a mucosal prolapse which was treated. CONCLUSIONS: Perineal rectosigmoidectomy with levatoroplasty for complete rectal prolapse is a safe technique with acceptable short-term functional results; however, it is not recommended for rectal prolapse patients with diarrhea-predominant irritable bowel syndrome.

Annuloaortic ectasia, cystic medial degeneration of the afflicted aortic wall leading to progressive dilatation, is often accompanied by Marfan's syndrome. Some portions of intimal flap is commonly demonstrated along the aorta in the noninvasive diagnosis of aortic dissection. We report the first case of circumscribed aortic dissection developed in a 28 year old obese non-Marfanoid patient. He was transferred after thrombolytic therapy at a community hospital because of severe chest pain and ST segment elevation. Transthoracic echocardiography showed markedly dilated aortic root, moderate amount of pericardial effusion, mild aortic regurgitation in spite of normal regional wall motion of left ventricle. Intimal flap, characteristic of aortic dissection, was not seen with computed tomography. Intimal tear was demonstrated just above aortic valve only by transesophageal echocardiography. Two parallel intimal tear and small circumscribed dissection was demonstrated by autopsy.

PURPOSE: This study was undertaken to eveluate the early results of the laparoscopic suture rectopexy in the treatment of rectal prolapse. METHODS: From May 1999 to July 2001, laparoscopic suture rectopexy (LSR) was successfully performed in 26 patients and the results were compared to those of 5 patients with open suture rectopexy (OSR) and 6 patients with open resection rectopexy (ORR). Preoperative and postoperative functional assessment included Wexner's incontinence score, constipation score, and anorectal manometry. RESULTS: Immediate postoperative morbidity was minimal in all groups. Bowel function was resumed significantly sooner (P=0.001), the numbers of the analgesics injection were significantly fewer (P<0.001) and postoperative hospital stay was significantly shorter (P<0.001) in the LSR than in the open groups. Postoperatively, the anal resting and squeezing pressures increased slightly and Wexner's incontinence score decreased significantly in all groups of patients. Constipation score decreased slightly in all groups of patients after surgery. There was one mucosal prolapse recurrence after surgery in the LSR. CONCLUSIONS: Laparoscopic suture rectopexy for rectal prolapse can be performed safely. Recovery is uneventful and of shorter duration after the laparoscopic than after the open approach. Functional results are obtained similarly with both approaches.

Although trivalent subunit vaccine has been available, the influenza vaccine has been under-utilized because of cumbersome route of vaccination and low level of protection. Therefore, there has always been a great need to develop live attenuated influenza vaccine which can be administered through nasal route and elicit better immunogenicity. Through conventional repeated passage at low temperature, a live influenza vaccine carrier could be established. By reassortant formation between the 'cold- adapted' vaccine carrier and virulent strains, a prototype of trivalent live influenza vaccine is developed. Influenza A virus was adapted to replicate at low temperature. Serial passage at progressively lower temperature (30degrees C, 27degrees C and 24degrees C)resulted in the generation of cold-adapted (ca), temperature-sensitive (ts) mutant and attenuation (att) phenotype. This strain was evaluated for their ability to protect mice from challenge with same subtype and different subtype of influenza A virus. The study showed that vaccination of mice with live attenuated influenza virus provided complete protection against homologous and heterologous virus challenge. We also evaluated therapeutic potential of ca influenza virus. The mice infected with ca virus before challenge with wild type viruses or infected with simultaneously showed reduced clinical symptoms suggesting potential therapeutic effects.

Transarterial chemoembolization (TACE) is a common treatment for unresectable hepatocellular carcinoma (HCC). The most common complications after TACE are non-specific symptoms called post-embolization syndrome, such as abdominal pain or fever. Rare complications, such as liver failure, liver abscess, sepsis, pulmonary embolism, cholecystitis, can also occur. On the other hand, gallbladder perforation is quite rare. This paper reports a case of gallbladder perforation following TACE. A 76-year-old male with a single 9-cm-sized HCC underwent TACE. Five days after TACE, he developed persistent right upper quadrant pain and ileus. An abdomen CT scan confirmed gallbladder perforation with bile in the right paracolic gutter and pelvic cavity. Percutaneous transhepatic gallbladder drainage was performed with the intravenous administration of antibiotics. After 1 month, the patient underwent right hemihepatectomy and cholecystectomy. Physicians should consider the possibility of gallbladder perforation, which is a rare complication after TACE, when unexplained abdominal pain persists.

BACKGROUND/AIMS: With the development of self-expanding metallic stents, colonic obstruction can be relieved without the need for surgery. The results of preoperative placement of stents for malignant colorectal obstruction might be different according to the obstructing lesion. The objective of this study was to compare clinical improvement rates and operative results after preoperative placement of stents for malignant colorectal obstruction according to the location of the obstructing lesion. METHODS: This is a retrospective study including 57 patients who underwent self-expanding metallic stent insertion for obstructing resectable colorectal cancers. Patients were classified into three groups according to the location of the lesion as follows: proximal to the sigmoid colon (Group A), sigmoid colon (Group B), and rectum (Group C). RESULTS: The number of patients in A, B, and C groups was 13, 22, and 22, respectively. No significant differences in age, gender, stent type, and accompanying diseases among the three groups were observed. There were no significant differences in stent-related complications, clinical improvement rates, and one-stage resection rates among the three groups. The postoperative complications, the requirement rate of ICU care, the period of ICU stay, postoperative hospital stay, and hospital mortality did not significantly differ among the three groups. CONCLUSIONS: Clinical improvement rates and operative results after successful placement of stents for obstructing resectable colorectal cancers are not different according to the location of the obstructing lesion, suggesting that preoperative stenting for one-stage curative resection is useful, irrespective of the location of lesion.

PURPOSE: This study was undertaken to identify factors influencing fecal incontinence in rectal prolapse. METHODS: The clinical and anorectal physiologic data (anal manometry, rectal sensitivity test, pudendal nerve terminal motor latency (PNTML)) of 42 complete rectal prolapse patients were collected in a prospective database and were analyzed according to Wexner's incontinence score (0-20). RESULTS: The mean Wexner's incontinence score was 10.6. Females (n=24) were more prone to be incontinent than males (n=18)(incontinence score 14.8 vs 5.1, p<0.001). A linear regression analysis showed that increased age (r= 0.497, p=0.001), decreased maximum resting pressure (MRP) (r= 0.686, p<0.001), decreased maximum squeezing pressure (MSP)(r= 0.789, p<0.001), decreased maximal rectal tolerable volume (MTV) (r= 0.386, p=0.012) influenced the incontinence score. An absent rectoanal inhibitory reflex (RAIR) was not related to incontinence, but was related to significantly low resting anal pressure. Delayed PNTML did not influence incontinence or the MSP. In a multiple regression analysis, decreased MRP (beta= 0.383; p=0.002), decreased MSP (beta= 0.345; p =0.007) and female gender (beta=0.343; p=0.006) influenced incontinence significantly. CONCLUSIONS: Major factors influencing fecal incontinence in complete rectal prolapse were decreased MRP and MSP. Female patients were more prone to fecal incontinence than males. RAIR and MTV were not significant factors. PNTML did not show any relation to incontinence score or the anal pressure.

PURPOSE: Small-sized carcinoids, less than 1 cm, are easily detected using flexible sigmoidoscopy or total colonoscopy and can be treated by local excision. Recently, there has been many advances in the technique of endoscopic resection. The aim of this study was to determine the endoscopic findings of a rectal carcinoid and to evaluate the effectiveness of endoscopic resection. METHODS: We experienced 22 rectal carcinoids in 21 patients who were treated by endoscopic resection from June 1996 to February 1999. Nineteen cases were followed for an average of 21 months. Follow-up studies consisted of chest P-A, hepatic ultrasonography, and total colonoscopy. RESULTS: The male-to-female ratio was 1.6 to 1. The most common age group was the 4th decade. The tumor was located at the lower rectum in 10 patients, at the upper rectum in 10 patients, and at the rectosigmoid junction in 2 patients. The tumor sizes ranged from 3 to 12 mm in diameter and were smaller than 10 mm in 20 cases (90.1%). Endoscopic finding revealed that the tumors were covered by a normally appearing mucosa in 12 cases, were yellow-discolored polyps in 17 cases, and were sessile-type tumors in 19 cases. The method of treatment was an endoscopic mucosal resection (EMR, 14 cases) or a snare polypectomy (8 cases). Microscopically positive margins were noticed in four cases, two cases of EMR (2/14, 14%) and two cases of snare polypectomy (2/8, 25%). All the patients were alive and clinically free of disease; however, the duration of the follow-up is short. CONCLUSIONS: Endoscopic resection for rectal carcinoid tumors smaller than 1 cm in diameter is a safe, functional, time-saving, and effective treatment. If the tumor suggests a carcinoid, EMR is advised rather than a polypectomy even though the tumor is small. Microscopically positive margins are not absolute indications for further surgery in the treatment of carcinoids smaller than 1 cm in diameter. It is much more important for an endoscopist to be confident that the endoscopic resection is done completely. It is necessary to identify the factors influencing the malignancy potential and to have a longer follow-up.
