Role of Crural Diaphragm after Esophagogastrectomy / 대한흉부외과학회지

BACKGROUND: The high pressure zone(HPZ) at the gastroesophageal junction is an important barrier for prevention of gastroesophageal reflux. Smooth muscle layers in the lower esophageal sphincter mainly contributes to HPZ at the throacoabdominal junction. The purpose of this study was to investigate the manometric characteristics of the thoracoabdominal junction in patients after surgical removal of the lower esophageal sphincter. MATERIAL AND METHOD: Twenty two patients with prior esophagogastrectomy(10 Ivor-Lewis method and 12 left thoracotomy) and 30 normal adults(control group) were studied manometrically. RESULT: Esophageal manometry showed a HPZ and pressure inversion point distal to the anastomosis in 12 of 22 patients(2 of 10 patients with Ivor-Lewis method and 10 of 12 patients with left thoracotomy) and a HPZ in 30 of 30 normal adults. The location of HPZ from nostril was not significant different between the two groups(42.5+/-0.9cm in patients and 43.9+/-2.1cm in the control), while the length of HPZ was shorter in patients than in the control(2.13+/-0.6cm vs 2.83+/-0.59cm). By SPT and RPT, pressures of HPZ at rest were lower in patients(13.78+/-1.63mmHg, 28.58+/-6.06mmHg) than in control(20.3+/-4.95mmHg, 42.80+/-15.91mmHg). The HPZ relaxed partially in response to deglutition(84.4% in patient, 90.5% in control group) and contracted in response to increased intra- abdominal pressure induced by leg lifts(HPZ/ Intra-abdominal pressure= 1.81+/-0.23 in patient, 2.13+/-0.58 in control group). CONCLUSION: This study shows an HPZ at thoracoabdominal junction after surgical removal of the lower esophageal sphincter. It may be important to perform a crural myoplasty during esophageal reconstruction after esophagogastrectomy because crural diaphragm acts as sphincter like HPZ at the thoracoabdominal junction.

Outcome of Chemotherapy with Pulmonary Tuberculosis Resistant to Isoniazid and Rifampin / 결핵

BACKGROUND: The treatment for multi-drug resistant tuberculosis(MDRTB) is encountered to be important clinically, but there are still a few reports about it all over the world. So, we evaluated the outcomes of only chemotherapy for the pulmonary MDRTB retrosptctively. METHOD: We reviewed the clinical courses of 63 patients with pulmonary disease due to M.tuberculosis resistant to rifampin and isoniazid who were under follow-up between March 1996 and June 1996 after hospitalization at our hospital between January 1993 and January 1996. We performed cohort retrospective study for all these patient's records. Their regimens were selected individually and preferably included four medications that they had not been given previously and to which the strain was fully susceptible. RESULTS: The 63 patients(mean age, 43.2 years) had previously received a median 5.1drugs. Fifty two(82.5%) patients responded to chemotherapy(as indicated by negative sputum cultures for at least three consecutive months); eleven patients(17.5%) had no response, as shown by continually positive cultures. In a univariate analysis, an unfavorable response was significantly associated with greater number of resistant drugs before the current courses of therapy(relative risk 21.5; 95 percent confidence interval, 1.2-3.0; p<0.05). The mean period of follow-up was seventeen months. There was no relapse subsequently among the patients with responses. There was no death related to tuberculosis. CONCLUSION: In this report from National Masan Tuberculosis Hospital in Korea, multi-drug resistant pulmonary tuberculosis responded relatively well to carefully selected regimens.

Pulmonary Resection in the Treatment of Multidrug-Resistant Tuberculosis / 결핵

BACKGROUND: Recent outbreaks of pulmonary disease due to drug-resistant strains of Mycobacterium Tuber-culosis have resulted in significant morbidity and mortality in patients worldwide. We reviewed our experience to evaluate the effects of pulmonary resection on the managenent of multidrug-resistant tuberculosis. METHOD: A retrospective review was performed of 41 patients undergoing pulmonary resection for multidrug-resistant tuberculosis between January 1993 and December 1997. We divided these into 3 groups according to the radiologic findigs : (1) patients who have reasonably localized lesion ( Localized Lesion Group ; LLG) (2) patients who have cavitary lesion after pulmonary resection on chest roentgenogram (Remained Cavity Group : RCG). (3) patients who have Remained infiltrative lesions postoperatively (Remained infiltrative group : RIG). We evaluated the negative conversion rate after resection and overall response rate of the groups. Then they were compared with the results of the chemotherapy on the multidrug-resistant tuberculosis which has been outcome by Goble et al. Goble et al reported that negative conversion rate was 65% and overall response rate, 56% over a mean period of 5.1 months. RESULTS: Seventy five point six percent were men and 24.4% woment with a median age of 31 years (range, 16 to 60 years). Although the patients were treated preoperatively with multidrug regimens in an effort to reduce the mycobacterial burden, 22 of 41 were still sputum culture positive at the time of surgery. 20 of 22 patients (90.9%, p<0.01) responded which is defined as negative sputum cultures within 2 months postoperative. Of 26 patients with the sufficient follow up data, 19 have Remained sputum culture negative for a mean duration of 25.7 months (73.1%, p<0.05). The bulk of the disease was manifest in one lung, but lesser amounts of contralateral disease were demonstrated in 15, consisted of 8 in RIG and 7 in RCG, of 41. 12 of 12 patients (100%, p<0.01) who were sputum positive at the time of surgery in LLG converted successfully. 14 of 15 patients (93.3%, p<0.05) with the follow up have completed treatment and not relapsed for a mean period of 25.7 months. The mean length of postoperative drug therapy off LLG was 12.2 months. In RIG, postoperative negative conversion rate was 83.3% which was not significant statistically. There was a statistical significance in overall response rate (100%, p<0.05) of RIG for a mean period of 24.4 months with a mean length of postoperative chemotherapy, 11.8 months. In RCG a statistically lower overall response rate (14.3%, p<0.01) has been revealed for a mean duration of follow up, 24.2 months. A negative conversion rate of RCG was 75% which was not significant statistically. CONCLUSION: Surgery plays an important role in the management of patients with multidrug-resistant Mycobacterium tuberculosis infection. Aggressive pulmonary resection should be performed for resistant Mycobacterium tuberculosis infection to avoid treatment failture or relapse. Especially all cavitary lesions on preoperative chest roentgenogram should be resected completely. If all them could not be resected perfectly, you should not open the thorax.

A Comparative Study of Effect of Secondary Anti-tuberculosis Drugs in the Retreatment of Pulmonary Tuberculosis / 결핵

BACKGROUND: In the management of patients whose primary chemotherapy has failed, careful assessment is essential. It is important to find out as accurate a chemotherapy history as possible. Preferably it should contain the drugs which has never used before. The purpose of present study is establishment of retreatment regimen for pulmonary tuberculosis. The present report concerns the results of retreatment of pulmonary tuberculosis patients treated at National Masan Tubersulosis Hospital. METHOD: Retrospective cohort study was made 104 drug-resistant pulmonary tuberculosis patients who were treated by five regimens between Jan. 1994 and Now. 1996. All the patients taken medicine for second anti-tuberculosis regimens for the first time. We separated the patients by three groups(Group l : OFX+PTA+CS+PAS+Aminoglycoside, Group ll : PZA+PTA+CS+PAS+Aminoglycoside, Group lll : PZA+OFX+PTA+PAS+Aminoglycoside). RESULTS: The age distribution was most frequent in fourth decade(36patients, 34.6%) and the mean age was 42.6 year. The sex distribution was most frequent in the males(81patients, 85.7%). There was 31 patients(29.8%) with combined diseaes, 18 patients with complication and 24 patients(27.9%) with family history. Primary chemotherapy regaimens were HERAZ(S or K) in 48 patients (46.2%), HER(S or K) in 41 patients (39.4%) and others in 15 patients(14.4%). Result of drug sensivivity test showed that the resistance to INH and RFP is in 68 patients(65.4%), RFP is in 12 patients(11.5%), INH s in 3 patients(2.9%) and all sensitive to INH and RFP is 3 patients(2.9%). The clinical symptoms on admission were coughing(89.4%), sputum(69.2%), dyspenea on exertion(37.5%), weight loss(33.7%) blood tinged sputum (15.4%) and otheres. The extent of disease on the radiograph was far-advanced in 73 patients (70.2%), moderate in 28 patients(26.9%) and minimal in 3 patients(2.8%). The side effects for drugs were gastrointestinal troubles in 31 patients(29.8%), arthralgai in 22 patients(21.2%), skin rash in 12 patients(11.5%) and others. The negative conversion rate on sputum AFB smear was 85.6%(87.5% in Group l, 80% in Group ll and 90.5% in Group lll). The average negative conversion time on sputum was 4 month(4.0 month in Group l, 4.6 month in Group ll and 3.0 month in Group III). CONCLUSION: In the retreatment of pulmonary tuberculosis, ofloxacin is useful drug for the patients who are not available to use PZA and combination of PZA and OFX can be use effectively substively substituting for CS.

Analysis of Specificity for Tumor Marker CYFRA 21-1 in Patients with Pulmonary Tuberculosis / 결핵

BACKGROUND: CYFRA 21-1 is a tumor marker which measures a fragment of cytokeratin 19 expressed by epithelial cells in bronchus. It is known that cytokeratin 19 is abundant in squamous epithelial cell cancer of the lung. However, if the incidence of elevated serum CYFRA 21-1 level in patients with benign lung diseases or pulmonary tuberculosis with severe parenchymal damage is high the specificity of CYFRA 21-1 could be decreased. The purpose of this study is to investigate the changes of serum CYFRA 21-1 according to the degree of parenchymal damage and the usefulness of CYFRA 21-1 for diagnosing possibly combined lung cancer in patients with pulmonary tuberculosis. METHOD: We studied the changes of serum CYFRA 21-1 according to the sputum AFB stain, radiologic manifestation and history of treatment in 81 patients with pulmonary tuberculosis, and 20 healthy persons, 25 patients with lung cancer, as a control group. CYFRA 21-1 concentration in serum was quantified by the immunoradiometry assay(Centocor (R)) RESULT: The results were as follow; Serum CYFRA 21-1 level was significantly lower in patients with pulmonary tuberculosis(1.54+/-1.19ng/mL, p<0.01) as compared to patients with lung cancer( 12.25+/-15.97ng/mL), and was slightly higher than the level in heathy persons(0.90+/-0.49ng/mL) but there was no significant difference. Serum CYFRA 21-1 level was below the cut-off value of 3.3ng/mL in 95 percent of patients with pulmonary tuberculosis but it was above the cut-off value in 64 percent of patients with lung cancer. Serum CYFRA 21-1 level was significantly higher in the initial treatment group(1.91+/-1.55ng/mL, p<0.05) as compared to the treatment failure group (0.92+/-0.30ng/mL). According to the sputum AFB smear, serum CYFRA 21-1 level in patients with negative result was slightly higher than the level in patients with positive result but there was no significant difference. According to the radiologic manifestation, serum CYFRA 21-1 level was significantly higher in patients with infiltrative lesion (2.15+/-1.63ng/mL, p<0.01) as compared to patients with destructive lesion (1.04+/-0.54ng/mL). As the size of cavity or destructive lesion was larger, the level was significantly lower(p<0.05). CONCLUSION: As serum CYFRA 21-1 level was significantly higher in the initial treatment group and patients with infiltrative lesion, it suppose to be closely related with the degree of parenchymal damage of the lung of the pulmonary tuberculosis. However CYFRA 21-1 could be useful method for diagnosing lung cancer even in patients with pulmonary tuberculosis combined with lung cancer because of the fact that it was below the cutoff value of 3.3ng/mL in 95 percent of patients with pulmonary tuberculosis.
