Manometric study and prolonged pH monitoring of esophagus in patients with hiatus hernia before and after operation.

The pathophysiology of the lower esophagus in 18 patients with hiatus hernia and 15 normal controls was investigated by esophageal manometry and prolonged pH monitoring. Thirteen patients with symptoms of severe gastroesophageal reflux had lower than normal pressures at the gastroesophageal junction. In 5 patients without symptoms, the pressure was normal. Nine of the 13 patients were inadequately controlled by conservative measures and underwent Nissen or Dor-Nissen fundoplication. All were free of esophageal symptoms postoperatively. Fundoplication resulted in a significant increase in the lower esophageal pressure. Prolonged esophageal pH monitoring showed significant improvement in all indices. Hiatus hernia and gastroesophageal reflux are related etiologically. However, further observations are needed to explain the association between reflux esophagitis and hiatus hernia. Nissen and Dor-Nissen fundoplications restored competence to the gastroesophageal junction as judged by esophageal manometry and prolonged pH monitoring.

Detection of gastric cancer by a combination of tissue polypeptide antigen (TPA), lipid-bound sialic acid (LBSA) and carcinoembryonic antigen (CEA).

In this study, the clinical significance of the tumor markers, tissue polypeptide antigen (TPA) and lipid-bound sialic acid (LBSA) in conjunction with carcinoembryonic antigen CEA, was tested in 52 gastric cancer patients. The incidence of elevated serum levels of these 3 markers was as follows: 63% (33/52) for TPA; 40% (21/52) for LBSA; 21% (11/52) for CEA. In a combination assay using all three tumor markers, 37 out of 52 gastric cancer patients (71%) showed a positive combination assay, while 5 out of 20 normal subjects (25%) showed a positive combination assay. In a discriminant analysis of the resulting data, 18 out of 52 gastric cancer patients (35%) were classified correctly based on an analysis of CEA alone. Furthermore, 25 out of 52 gastric cancer patients (48%) and all 20 normal subjects (100%) were classified correctly based on an analysis of all three variables. Our data suggest that TPA and LBSA are more sensitive than CEA as markers of gastric cancer, and that the simultaneous measurement of TPA and LBSA in conjunction with CEA is more useful in cancer detection than the measurement of CEA alone.

Long-term results after surgical correction of anorectal malformations.

Our surgical experience with 101 cases of anorectal malformations during the past 21 years includes staged abdominoperineal rectoplasty in 49 patients, perineoplasty in 35 patients, and permanent colostomy in 2 patients. The observations of this clinical study are especially focused on long-term anal continence. The functional results were assessed clinically on the basis of Kelly's criteria (5), and by manometric and radiologic studies. Fifty-one patients, aged 5-25 years, were personally interviewed and 36 of these 51 had manometric and radiologic studies to evaluate postoperative continence. Patients with low-type lesions were more likely to be continent, while patients with high-type lesions had more problems with continence, because a functional internal sphincter is absent in high-type lesions. However, continent patients with high-type lesions as well as those with low-type lesions characteristically had a marked high-pressure zone in the anal canal and an acute anorectal angulation in the defecogram . On the other hand, in the patients with fair or poor results, neither a high-pressure zone in the anal canal nor marked anorectal angulation was found. These results indicate that achievement of continence in patients with a high-type anomaly treated by abdominoperineal rectoplasty depends upon bringing the terminal bowel down exactly within the sling of the puborectalis and careful dilatation of the new anal canal after the creation of a cosmetically satisfactory anal opening.

Serum gastrin levels and lower oesophageal sphincter pressures in infants with congenital hypertrophic pyloric stenosis.

Serum gastrin levels in 16 patients with congenital hypertrophic pyloric stenosis (CHPS) were measured and oesophageal manometric studies were performed in 14 of these 16 patients before and after pyloromyotomy. Hypergastrinaemia was found in the patients with CHPS, and the 7th postoperative serum gastrin level was much higher than the preoperative pressure. However, there was no significant correlation between the LES pressure change and the serum gastrin change. These results indicate that competence of LES after pyloromyotomy in patients with CHPS is maintained not only by endogenous gastrin rise but also by other factors.

New application of catecholamine fluorescence histochemistry using glyoxylic acid for diagnosis of Hirschsprung's disease by rectal biopsy.

Catecholaminergic innervation was studied in the rectal biopsy specimen obtained from patients with Hirschsprung's disease. The histofluorescence of catecholamine was examined using glyoxylic acid and magnesium without freeze-drying. Aganglionic specimens exhibited no fluorescent network of terminals or fibres in the submucosal plexus, whereas ganglionic specimens showed ganglion cells surrounded by a network of catecholaminergic terminals and fibres. These results of rectal biopsy could be obtained easily and quickly with good reliability. Examination of the catecholaminergic innervation by this histofluorescence method provides a new approach to the diagnosis of Hirschsprung's disease.

Correlation between carcinoembryonic antigen in gastric cancer tissue and survival of patients with gastric cancer.

Gastric cancer specimens obtained from 162 patients who had undergone radical surgery with the routine postoperative administration of both mitomycin C and 5-fluorouracil were stained for carcinoembryonic antigen (CEA) by the unlabeled antibody enzyme technique. The CEA (-/+) group (92 cases) consisting of the negative and weakly positive staining cases had a significantly better survival rate over a period of 5 years than the CEA (++) group (70 cases) which comprised only strongly positive cases. The CEA (-/+) group with differentiated adenocarcinoma had the best prognosis and the 5-year survival rate was significantly higher than those of the other three groups. Among stage II and III carcinomas, the postoperative survival rate was significantly better in the CEA (-/+) group than in the CEA (++) group. Among the patients with lymph node metastasis, the postoperative survival rate was low, especially in the CEA (++) group. The present data suggest that staining for CEA in tissue sections of stomach carcinoma may be helpful in differentiating among tumors that appear similar by conventional histological methods, thus providing a new means for obtaining more precise prognostic information.

[Endoscopic preoperative intralesional injection of OK-432 in early gastric cancer].

The study group consisted of 35 patients with early gastric cancer, 16 of whom were admitted for preoperative immunotherapy. Ten to 40 K.E. of OK-432 was injected intralesionally by endoscope, and then gastrectomy was performed. After the intralesional injection, fever, nausea, vomiting and epigastralgia occurred. In cancer lesion and regional lymph node, histological findings from OK-432 treated group were compared to those of the control group. Lymphoid cell infiltration at cancer lesion was marked in OK-432 treated group, and degenerated cancer cells were found in 3 cases. On the other hand, lymphoid follicles showed a marked statistical increase in OK-432 treated group. Also the cases with marked lymphoid follicle showed increased numbers of peripheral blood lymphocyte. From the results, intralesional injection of OK-432 may confirm the tumor-associated antigenicity and serves as a useful method to potentiate the specific and/or non-specific immunity in regional lymph nodes.

Conservative surgery for regional lymphadenectomy in the treatment of early gastric carcinoma.

The relationship between lymph node metastases and postoperative prognosis in 209 patients with early gastric cancer was studied. As to the postoperative prognosis in relation to the extent of lymph nodes dissection, no significant difference was observed among the age-corrected 5-year survival rates following three surgical procedures in patients with early gastric cancer. Age-corrected 5-year survival rates were 0.92 +/- 0.44 R1-resection, 0.95 +/- 0.44 in R2-resection, and 1.00 +/- 0.06 in R3-resection, respectively. In addition, in 71 patients including 33 with early gastric cancer and 38 patients with advanced but relative early gastric carcinoma, the relationship between the immunostatus and postoperative prognosis was investigated. Postoperative age-corrected 5-year survival rate (0.904 +/- 1.153) of the optimal responders with good immunostatus was significantly higher than that (0.582 +/- 1.153) of the suboptimal responders with impaired immunostatus (P less than 0.01). Thus, conservative surgery for regional lymphadenectomy may be an effective procedure for cure of early gastric carcinoma, particularly in cases of a carcinoma limited to the mucosal area of the stomach.

Prevention of gastroesophageal reflux using Nissen fundoplication in the staged repair of esophageal atresia with distal tracheoesophageal fistula.

To prevent the reflux of gastric contents into the bronchial tree through the tracheoesophageal fistula in patients with esophageal atresia with tracheoesophageal fistula, Nissen fundoplication was performed in the first-stage repair of staged operations. After elimination of the pulmonary complication, a correction of esophageal atresia and tracheoesophageal fistula was successfully performed through the extrapleural route at the age of 16 days. Thus, because Nissen fundoplication is simple to perform and effective in preventing gastroesophageal reflux, this procedure is considered to be useful in the staged repair of esophageal atresia with tracheoesophageal fistula.

Acetylcholinesterase activity in rectal mucosa and blood in the diagnosis of Hirschsprung's disease.

Histochemical and biochemical examinations of rectal biopsy specimens were performed in 13 patients with Hirschsprung's disease and in seven with idiopathic constipation and no megacolon. Serum and erythrocyte acetylcholinesterase (AchE) activity in these two groups was compared with that in 30 normal controls. AchE staining of rectal biopsy specimens proved to be a reliable and convenient diagnostic approach in patients with Hirschsprung's disease. Biochemical assay of AchE activity in rectal biopsy specimens was also of value in the diagnosis, however, there was an overlap between Hirschsprung's disease and idiopathic constipation. Erythrocyte AchE activity correlated well with AchE activity in rectal biopsy specimens. Therefore, assays of erythrocyte AchE activity provided useful additional information, especially in screening tests for Hirschsprung's disease.

Anal sphincter function and rectal reservoir after sphincter saving operations for carcinoma of the rectum.

Anal sphincter function and rectal reservoir were studied in 27 patients after low anterior resection, in 6 after Welch or Turnbull type pull-through surgery and in 3 after Bacon type pull-through surgery. Sixteen patients who had undergone right hemicolectomy served as a control group. Anal sphincter function immediately after low anterior resection was diminished, but improved during the following 6 months. Rectal capacity was much reduced immediately after surgery, but increased with time, and the neorectum could to some extent adapt to its new role as a reservoir. After pull-through operations, anal canal pressure and rectal compliance were significantly lower than after low anterior resection or right hemicolectomy. These findings may explain the increased frequency of bowel action after pull-through operations.

Immunoassessment of patients with gastric cancer. Using leukocyte migration inhibition (LMI) test.

Leukocytes from patients with gastric, colorectal or benign gastrointestinal disease, as well as those from normal control subjects, were tested by the leukocyte migration inhibition test (LMIT), using five different allogeneic 3 M KCl extracts of gastric cancer extracts. In LMIT with a single tumor extract, a pathological MI was found in 48% of 79 gastric cancer patients, a significantly higher figure than in the three other groups of patients (4-21%). In the panel mode of LMIT, that is, testing each blood sample with five different tumor extracts, 62/79 (79%) of patients with gastric cancer showed a positive reaction. Positive reactivity was significantly higher in patients with gastric cancer than in patients in the other groups and the frequency was higher in stage IV cases than in stage I-III cases, although the differences were not significant. In addition, the frequency of the positive reaction was unrelated to the degree of differentiation in adenocarcinoma. Positive reactivity increased in inverse proportion to the degree of nuclear grade (NG) (84% in NG I, 80% in NG II and 64% in NG III), but the correlation was not statistically significant.

Studies on effect of carcinoembryonic antigen on leucocyte migration inhibition test in patients with colorectal cancer.

Leucocyte migration inhibition test (LMIT) is a useful method to detect tumor associated antigens (TAA) in cancer patients. Carcinoembryonic antigen (CEA) is one of the best tumor markers for gastrointestinal cancer, and especially for colorectal cancer patients, who show high plasma CEA level frequently. In this study, we performed LMIT in 71 colorectal cancer patients with 3 M KCl extracts of cancer tissues and measured concentration of CEA in the plasma and the extracts of cancer tissue simultaneously. Although CEA in colorectal cancer extracts was individually varied from low to high in concentration, the levels of CEA had no relation to LMI reactivity. In addition, the LMI reactivity of colorectal cancer patients did not relate to the plasma CEA level of the corresponding patient. The results suggest that some antigens which induce leucocyte migration inhibition factor (LMIF) to lymphocytes from colorectal cancer patients might be different substances from CEA.

Manometric assessment of anorectal pressures in Hirschsprung's disease after Rehbein's operation with and without anorectal myectomy.

Anorectal manometric studies were performed on 15 patients with Hirschsprung's disease before surgery, on eight patients after Rehbein's procedure and seven patients after Rehbein's procedure with anorectal myectomy. The results were compared with those of 45 normal subjects. High anal resting pressure as well as an absence of the anorectal reflex proved to be responsible for obstructive symptoms in Hirschsprung's disease. Out of eight patients treated according to Rehbein's procedure, new internal sphincter relaxation was found in two, and anal resting pressures were significantly higher than those of the normal controls or of the patients treated according to Rehbein's procedure plus anorectal myectomy. It was demonstrated that anorectal myectomy is a more definitive procedure to restore the anal resting pressure to normal. Good postoperative continence can be achieved not only by the new internal sphincter relaxation but also by good propulsive movement which can overcome the remaining functional obstruction.

Intratumor chemoimmunotherapy with mitomycin C and BCG in C3H/He mice transplanted with MH134.

Experiments were performed to explore the influence of local chemoimmunotherapy by intratumoral administration of mitomycin C (MMC) and/or BCG on the survival rate, lymph-node metastasis, growth pattern of rechallenge tumor, and host immune function, using a host-tumor system consisting of C3H/He mice and syngeneic tumor MH134. Combined intratumoral regimens of MMC plus BCG yielded a significantly higher survival rate than those achieved with BCG or MMC alone. Furthermore, the incidence of metastatic involvement of regional lymph nodes was also remarkably reduced in the combined regimen group. The group given the combined MMC-BCG regimen also showed a marked suppression of the growth of rechallenge tumor after surgical removal of the primary tumor and showed a greater induction of tumor-specific immunity than that seen in the group given intratumoral BCG injection alone. Both the delayed-type hypersensitivity, as measured by the footpad swelling assay, and the antibody response in spleen lymphocytes, as estimated by the plaque-forming cell assay, were found to be substantially depressed following a systemic injection of MMC, whereas the intratumoral administration of MMC had little or no effect on these parameters.
