Two cases of early recurrence after transabdominal preperitoneal inguinal hernia repair.

We performed transabdominal preperitoneal inguinal hernia repair in 46 patients (58 diseases), two of whom experienced early recurrence after mesh repair. Case 1 was a 76-year-old man with a bilateral inguinal hernia (recurrence site, left indirect hernia) after appendectomy. The recurrence occurred 1 month after transabdominal preperitoneal inguinal hernia repair. The mesh was dislocated to the lateral side, and we repaired it using the direct Kugel® patch with an anterior technique. Case 2 was a 79-year-old man with a bilateral inguinal hernia (recurrence site, right direct hernia with an orifice >3 cm) after appendectomy. The recurrence occurred 3 months after transabdominal preperitoneal inguinal hernia repair. The mesh was dislocated to the lateral side, and we repaired it using an ULTRAPRO® Plug with an anterior technique under laparoscopic observation. We believe the recurrences resulted from insufficient internal exfoliation and fixation affected by complicated exfoliation of the preperitoneal space with omental adhesion after intraperitoneal surgery.

Clinical Significance of Area of Psoas Major Muscle on Computed Tomography after Gastrectomy in Gastric Cancer Patients.

BACKGROUND: The measurement of a single abdominal image on computed tomography (CT) can provide an estimate of the total body skeletal muscle. We evaluate the change of the area of the psoas major muscle (PMMA) in a CT which was performed routinely after gastrectomy in gastric cancer. METHODS: A total of 119 gastric cancer patients who underwent gastrectomy were enrolled for the study. A CT image at the top of the iliac crest level was obtained at the following times: 3 postoperative months (POM), 6 POM, 1 postoperative year (POY), 2 POY, 3 POY, and 5 POY. We analyzed the change rate of PMMA after gastrectomy and before or after recurrence. RESULTS: PMMA change after gastrectomy was approximately between -8 and -10% over the 5-year observation period. PMMA in the R2 (macroscopic residual tumor)/recurrence group was lower than that in the no recurrence group, and a significant difference was observed at 2 POY (-21.7 ± 3.6% vs. -7.9 ± 2.3%, p < 0.01). PMMA after freshly diagnosed recurrence had decreased significantly by 14.1 ± 1.8% (p < 0.01). CONCLUSIONS: Evaluation of PMMA change by CT after gastrectomy could assist in the diagnosis of the progression of cancer state in gastric cancer patients.

Seven esophageal perforation cases after aortic replacement/stenting for thoracic aortic dissection or aneurysm.

BACKGROUND: Esophageal perforation after aortic replacement/stenting for aortic dissection or aneurysm is a rare but severe complication. However, its cause, standard treatment, and prognosis are unclear. We analyzed the treatment and outcome retrospectively from seven cases experienced at our hospital. CASE PRESENTATION: The median age of the patients was 70 years (range, 41-86), and six of the seven cases were male. As the first treatment, aortic replacement techniques were performed in five, and thoracic endovascular aortic repair (TEVAR) procedure was performed in two. We evaluated the treatment of the perforation, the cause of death, and the median survival time after reparative surgery (esophagectomy). Initial treatment of the perforation was esophagectomy without reconstruction in six and esophagogastric bypass (later, esophagectomy was performed) in one. Three of seven cases could be discharged from hospital or moved to another hospital, but two of these three cases died of major bleeding on postoperative days 320 and 645. The other four esophagectomy cases died in hospital because of sepsis on postoperative days 14, 30, and 41 and major bleeding on postoperative day 54. The one surviving case was a 65-year-old man who underwent reconstruction, and was still alive without signs of infection at 424 days postoperatively. CONCLUSION: The prognosis of esophageal perforation cases after aortic replacement/stenting for thoracic aortic dissection or aneurysm is poor, though there were some cases with relatively long survival. Therefore, the indication for invasive esophagectomy should be decided carefully. Control of infection including regional infection is essential for successful treatment.

A randomized clinical study on postoperative pain comparing the Polysoft patch to the modified Kugel patch for transinguinal preperitoneal inguinal hernia repair.

PURPOSE: The transinguinal preperitoneal approach is a relatively new technique for inguinal hernia repair. Two types of memory-ring mesh are available in Japan: the modified Kugel patch (MK) and the Polysoft patch (PP). We tested the hypothesis that the PP is noninferior to the MK with respect to chronic postoperative pain. METHODS: An unblinded randomized controlled trial was conducted to assess the noninferiority of PP compared to MK with a 5 % noninferiority margin. A total of 442 inguinal hernia patients operated on from November 2010 to December 2012 were included in this study. The primary endpoint was the pain score assessed by the visual analog scale (VAS) (0-1 vs. 2-10) 1 year after surgery. RESULTS: The patients were randomized to the PP and MK groups (n = 221 each). One year after surgery, 206 patients (95.4 %) in the PP group and 182 patients (89.6 %) in the MK group rated pain at 0-1 on the VAS scale. According to this rating, the PP group appeared not to be inferior to the MK group (95 % confidence interval, 0.7-10.7 %, P < 0.05). Furthermore, crude superiority tests, adjusting for 1 month of pain, denoted that the outcomes were significantly improved with the PP compared to the MK. CONCLUSIONS: The use of the PP was noninferior to the MK with respect to the severity of postoperative chronic pain scores 12 months after surgery.

Laparoscopic lysis for jejunostomy-related ileus following laparoscopy-assisted total gastrectomy: a case report.

A 54-year-old man was admitted to our hospital with severe nausea, vomiting and abdominal pain. He had had laparoscopy-assisted total gastrectomy with Roux-en-Y reconstruction and tube jejunostomy for gastric cancer 2 years earlier. Abdominal CT revealed that the duodenum and upper jejunum were markedly dilated and that the dilated jejunum had collapsed at the jejunostomy site. Emergency laparoscopic surgery with three ports was performed for jejunostomy-related ileus. Abdominal adhesion was very small, and the Roux-en-Y limb was rotated counterclockwise at the jejunostomy site. A magnified laparoscopic view showed that the site of peritoneopexy was the axis of rotation. After the axis was dissected with a Harmonic scalpel, the rotation was released immediately. The patient's postoperative course was uneventful and he was discharged 4 days after the operation. Because the axis of rotation was identified easily by laparoscope, laparoscopic surgery was a safe and useful technique for a patient with jejunostomy-related ileus.

Phase I clinical study of multiple epitope peptide vaccine combined with chemoradiation therapy in esophageal cancer patients.

BACKGROUND: Chemoradiation therapy (CRT) has been widely used for unresectable esophageal squamous cell carcinoma (ESCC) patients. However, many patients develop local recurrence after CRT. In this study, we hypothesized that the immunotherapy by peptide vaccine may be effective for the eradication of minimal residual cancer cells after CRT. This study was conducted as a phase I clinical trial of multiple-peptide vaccine therapy combined with CRT on patients with unresectable ESCC. PATIENTS AND METHODS: HLA-A*2402 positive 11 unresectable chemo-naïve ESCC patients were treated by HLA-A*2402-restricted multi-peptide vaccine combined with CRT. The peptide vaccine included the 5 peptides as follows; TTK protein kinase (TTK), up-regulated lung cancer 10 (URLC10), insulin-like growth factor-II mRNA binding protein 3 (KOC1), vascular endothelial growth factor receptor 1 (VEGFR1) and 2 (VEGFR2). CRT consisted of radiotherapy (60 Gy) with concurrent cisplatin (40 mg/m²) and 5-fluorouracil (400 mg/m²). Peptide vaccines mixed with incomplete Freund's adjuvant were injected subcutaneously once a week on at least 8 occasions combined with CRT. RESULTS: Vaccination with CRT therapy was well-tolerated, and no severe adverse effects were observed. In the case of grade 3 toxicities, leucopenia, neutropenia, anemia and thrombocutopenia occurred in 54.5%, 27.3%, 27.3% and 9.1% of patients, respectively. Grade 1 local skin reactions in the injection sites of vaccination were observed in 81.8% of patients. The expressions of HLA class I, URLC10, TTK, KOC1, VEGFR1 and VEGFR2 antigens were observed in the tumor tissues of all patients. All patients showed peptide-specific cytotoxic T lymphocytes responses in at least one of the 5 kinds of peptide antigens during the vaccination. Six cases of complete response (CR) and 5 cases of progressive disease (PD) were observed after the 8th vaccination. The 4 CR patients who continued the peptide vaccination experienced long consistent CR for 2.0, 2.9 4.5 and 4.6 years. CONCLUSIONS: A combination therapy of multi-peptide vaccine with CRT can successfully be performed with satisfactory levels of safety, and application of this combination therapy may be an effective treatment for patients with unresectable ESCC.

Recurrent laryngeal nerve monitoring during thoracoscopic esophagectomy.

INTRODUCTION: There have been several reports on the feasibility and curability of thoracoscopic esophagectomy, which may reduce injury to the thoracic cage and decrease the invasiveness of surgery. Although the recurrent laryngeal nerve (RLN) is identified and kept intact during operations, RLN palsy sometimes occurs. Currently, surgical aides, including intraoperative neurological monitoring, are being utilized to avoid RLN injury during thyroid surgery. This system is utilized during thoracoscopic esophagectomy in the prone position. PATIENTS AND METHODS: Seven consecutive patients (six men, one woman; age range 62-74 years; mean 68 years) were included. Patients underwent general anesthesia and were intubated using the NIM TriVantage™ electromyography (EMG) tube. One-lung ventilation was performed with an endobronchial blocker. Thoracoscopic esophagectomy was performed in the prone position. The nerve stimulator was calibrated to 0.5 mA, and after the RLN was visually identified it was subsequently stimulated, which also confirmed normal machine functioning. In some situations, in the absence of a response, stimuli were increased to 1.0 mA and then 2.0 mA. RESULTS: Intraoperatively, all seven patients had their nerve signals monitored. In one case, a nerve signal disappeared after complete lymph node dissection along the left RLN. This system could identify the site of injury, and the thoracoscopic magnified view allowed the disrupted point to be located precisely. When we checked VTR after surgery, the source of injury was one point tension of the nerve pulled by fiber during lymph node dissection. CONCLUSIONS: Intraoperative RLN monitoring during thoracoscopic esophagectomy in the prone position, with one-lung ventilation performed using the TriVantage™ EMG tube and a bronchial blocker, is technically feasible, easy, and reliable.

The breath test system involving a novel tracer, ¹³C-uracil and Wagner-Nelson analysis: comparison with the gastric emptying scintigraphy.

BACKGROUND/AIMS: In this pilot study, a new breath test system for gastric emptying study has been proposed. METHODOLOGY: The system involves 13C-uracil as a novel tracer and the Wagner-Nelson method for analyzing breath data. RESULTS: In three healthy volunteers, the new breath system allowed quantification of gastric emptying profiles as accurately as the scintigraphic technique. CONCLUSIONS: Further validation studies with a lager sample size are needed.

Clinicopathological and prognostic significance of microRNA-107 and its relationship to DICER1 mRNA expression in gastric cancer.

microRNAs (miRNAs) are small non-coding RNAs that regulate target gene expression. It is known that miRNA-107 (miR-107) promotes cancer invasion and metastasis. However, the relationship between clinicopathological factors and the prognostic significance of miR-107 for gastric cancer patients remains elusive. In this study, we evaluated the prognostic value of miR-107 using tissue samples from gastric cancer patients. Furthermore, the relationship between miR-107 and the mRNA levels of its target gene DICER1 was examined. The expression levels of miR-107 and DICER1 mRNA in tumor tissues and adjacent normal tissues of 161 gastric cancer patients were examined (TNM stage I, 29 patients; stage II, 31 patients; stage III, 51 patients and stage IV, 50 patients). miR-107 levels were measured by Taqman microRNA assays, and DICER1 mRNA levels were measured by the Taqman real-time RT-PCR method. In the analysis by real-time PCR-based miRNA arrays using pooled RNA samples from five gastric cancer patients, expression of miR-107, miR-21, miR-196a, miR-26b, miR-9, miR-142-3p, miR-30b, miR-150, miR-191 and miR-17 was found to be upregulation. The mean expression level of miR-107 was significantly higher in the tumor tissues compared to that of normal tissues. In the comparison of clinicopathological factors, miR-107 expression showed significant association with depth of tumor invasion, lymph node metastasis and stage. In Kaplan-Meier survival curve analysis, overall survival rates (OS) and disease-free survival rates (DFS) of patients with high miR-107 expression were significantly worse than those of patients with low miR-107 expression. In the Cox multivariate analysis, it was shown that miR-107 expression in gastric cancer tissues was an independent prognostic factor for OS and DFS. Significant inverse correlations were demonstrated between miR-107 and DICER1 mRNA. Our results indicate that miR-107 may be useful as an effective biomarker for prediction of a poor prognosis in gastric cancer patients.

Chronic pain and discomfort after inguinal hernia repair.

PURPOSE: The purpose of this study was to estimate the incidence and degree of persistent chronic pain after inguinal hernia repair performed in our hospitals. METHODS: We mailed a questionnaire on the frequency and intensity of postoperative inguinal pain and discomfort to 219 adult patients who had undergone inguinal hernia repair in one of our hospitals more than 3 months previously. RESULTS: There were 191 (87.2%) respondents, 28 (14.7%) of whom reported pain and 33 (17.3%) reported discomfort. The frequency of pain was "rare" in more than half of the patients who reported pain. No patient reported "continuous" pain. The intensity of the pain was "mild" in most of the patients, and none reported "pain that required a painkiller". The answers on the face scale questionnaire (score "0" to "10") were "0" or "1" for most of the patients. The incidence of chronic pain and/or discomfort was significantly higher in women than in men, and tended to be higher in patients who had undergone repair using onlay mesh. CONCLUSIONS: The frequency and intensity of persistent chronic pain or discomfort after inguinal hernia repair was not high or severe. These data will be useful for further studies to determine the best treatment for adult inguinal hernia.

[Screening of sleep apnea syndrome with Sleeprecorder SD-101].

Polysomnography (PSG) has been the gold standard for the diagnosis of sleep apnea syndrome (SAS). However, PSG is not generally available since it is technically demanding, and cost and labour are necessary. Currently, there is growing demand for its diagnosis. Thus, simplified portable equipments have been increasingly utilized. Sleeprecorder SD-101 (Suzuken, Nagoya, Japan) is a pad-shaped and novel device for SAS analysis. A total of 162 sitting-sensor tips are 1.6 inch apart, embeded in the 55 x 22 inch pad, and capable of detecting load with precision of one gram. Sleeprecorder SD-101 placed beneath the chest can recognize respiratory pattern and record thoracic movement during sleep. SASLyzer (Suzuken, Nagoya, Japan), a software installed in a compatible PC, analyzes the data and indicates apnea-hypopnea index (AHI). We present a case of SAS in a 40-year-old man (181 cm, 98 kg) with peritonsillitis. We used Sleeprecorder SD-101 since he complained of severe snoring and excessive daytime sleepiness. He had severe SAS with AHI 50.7. Subsequently, conventional PSG also indicated AHI 77. In the present case with severe SAS, these two methods showed equivalent severity. Sleeprecorder SD-101 could be a useful device for screening of SAS patients.

Immunoreactivities for glutathione S-transferases and glutathione peroxidase in the lateral wall of pigmented and albino guinea pig cochlea.

Dark-skinned people are known to be more tolerant of ototraumatic noise than are light-skinned people, and pigmented animals are more tolerant of ototraumatic noise and aminoglycoside ototoxicity than are albino animals. Such tolerance may be dependent on the local ability of detoxification and antioxidant enzymes, including glutathione S-transferase (GST) and glutathione peroxidase (GSPx). In the present study, we examined the difference in GST/GSPx expression in the lateral wall of the cochlea between pigmented and albino guinea pigs. Eight-week-old male pigmented and albino guinea pigs were killed by transcardiac perfusion with 2% paraformaldehyde. The cochlear ducts were isolated, further fixed with 4% paraformaldehyde, decalcified, and then embedded in paraffin. Sections prepared at 5-microm thickness were incubated with anti-GST-alpha,-mu,-pi, or anti-GSPx antibody, reacted with Alexa Fluorconjugated secondary antibody, and examined under a Carl Zeiss Axioskop 2 plus fluorescence microscope. The cochlea ducts were also subjected to immunoelectron microscopy for GST-pi by the postembedment method. The stria vascularis of pigmented guinea pigs was strongly immunoreactive for GST-alpha,-mu,-pi, and GSPx, whereas no or only weak immunoreactivities were seen in the stria vascularis of albino guinea pigs. The spiral ligament showed positive but different immunoreactivities for these enzymes between the strains. Double-stained immunofluorescence micrographs for GST-pi and GSPx showed a close resemblance of localization between the two enzymes in both pigmented and albino guinea pigs. At the ultrastructural level, immunoreactivity for GST-pi was localized preferentially in the melanin cells of pigmented guinea pigs. These results suggest that correlation between pigmentation and inner ear susceptibility is, at least partially, attributed to the different distribution of GST/GSPx in the stria vascularis.

Endoscopic sinus surgery for the treatment of organized hematoma of the maxillary sinus.

Organized hematoma is a benign and non-neoplastic lesion, however, differential diagnosis from neoplastic diseases is always problematic, and patients are often forced to sustain excessive surgical invasion. We retrospectively studied the characteristics of imaging findings of organized hematoma of the maxillary sinus, and estimated the validity and effectiveness of endoscopic sinus surgery for the treatment of this disease. Three patients (2 men and a woman, ranging in age from 50 to 62 years) with organized hematoma of the maxillary sinus who underwent endoscopic sinus surgery were retrospectively analyzed. The diagnosis was provisionally made based on the findings of preoperative computed tomography (CT) and magnetic resonance imaging (MRI), and was confirmed by histopathological examinations of surgical specimens. CT revealed a well-defined expansile mass in the unilateral sinus associated with thinning and expansion of the medial sinus wall in all the cases. On contrast-enhanced images, patchy heterogeneous enhancement was observed. Intermingled low/intermediate/high signal intensity was seen on both T1- and T2-weighted MRI. The lesions were curetted via an endoscopic middle meatal antrostomy with the assistance of a microdebrider. None of the patients received arterial embolization or blood transfusion. Histopathological findings were consistent with those of organized hematoma. Their postoperative courses were uneventful, and all the patients are currently free from disease. We conclude that organized hematoma of the maxillary sinus can be successfully treated by endoscopic sinus surgery under accurate preoperative diagnosis and careful surgical planning.

Relationships between nasal obstruction, observed apnea, and daytime sleepiness.

OBJECTIVE: We administered a questionnaire survey to a working population in an attempt to clarify the relationships between self-reported nasal obstruction, observed apnea during sleep, and daytime sleepiness. STUDY DESIGN: A total of 7980 daytime workers were asked to complete questionnaires about nasal obstruction, apnea during sleep, and daytime sleepiness. Of the 7702 responses, the data from 4818 subjects were analyzed. Nasal obstruction and observed apnea were graded into 3 categories. Daytime sleepiness was assessed by the Epworth Sleepiness Scale. RESULTS: Subjects with chronic nasal obstruction had 5.22 and 2.17 times higher odds for having habitual observed apnea and excessive daytime sleepiness (EDS), respectively, compared with those without nasal obstruction (P < 0.001). After adjusting for 3 potential confounding factors (age, sex, and body mass index) and the presence of habitual observed apnea, odds ratios for having EDS decreased, but still remained significant. CONCLUSION: Nasal obstruction is likely to cause daytime sleepiness, at least in part, by causing sleep-disordered breathing including apnea during sleep.

Eikenella corrodens in head and neck infections.

BACKGROUND: Eikenella corrodens (E. corrodens) is a Gram-negative facultative anaerobic bacillus that originally was thought to be an attenuated and indigenous bacterium. In recent years, a number of reports have documented that E. corrodens can be a potential pathogen not only in immunocompromised patients but also in hosts with normal immunity. We herein study E. corrodens infections of the head and neck encountered in our department. METHODS: Twenty-two consecutive patients treated in our department for E. corrodens infections of the head and neck were retrospectively analyzed. Microbial specimens were subjected to light microscopic examination, aerobic culture using chocolate and sheep blood agar media, and anaerobic culture using Brucella HK agar medium. Cultured bacteria were subjected to antimicrobial susceptibility tests by means of the broth microdilution method. RESULTS: There were 16 males and 6 females with an average age of 29.9 years. Two patients had malignancy, while the other patients had no particular risk factors or underlying diseases. Infected sites were the ear in 6 cases, pharynx in 12 cases (tonsil in 10 cases), paranasal sinuses in 3 cases, and salivary gland in 1 case. Seventeen patients suffered polymicrobial infections. Staphylococcus and Streptococcus were the most frequently detected pathogens coexisting with E. corrodens, and mixed infections of E. corrodens and Streptococcus milleri group bacteria were prone to form abscesses. Isolated E. corrodens was susceptible to third-generation cephems (MIC90 = 0.15-0.25 microg/ml), carbapenems (MIC90 < or = 0.15 microg/ml), and new quinolones (MIC90 < or = 0.15 microg/ml), and resistant to oxacillin (MIC90 > 8 microg/ml), cefazolin (MIC90 > 4 microg/ml), macrolides (MIC90 = 4-8 microg/ml), and clindamycin (MIC90 > 4 microg/ml). CONCLUSIONS: E. corrodens infections of the head and neck occur most frequently in the tonsil even in hosts with normal immunity. Coexistence with Streptococcus milleri group bacteria and the use of ineffective antibiotics can be exacerbating factors. First-choice drugs for E. corrodens infections should be third-generation cephems, carbapenems, or new quinolones.

Superior protective and therapeutic effects of IL-12 and IL-18 gene-transduced dendritic neuroblastoma fusion cells on liver metastasis of murine neuroblastoma.

Fusion vaccine of dendritic cells (DCs) and tumor cells has the advantage of inducing an immune response against multiple tumor Ags, including unknown tumor Ags. Using the liver metastasis model of C1300 neuroblastoma cells, we assessed the protective and therapeutic effects of fusion cells transduced with the IL-12 gene and/or the IL-18 gene. Improving the fusion method by combining polyethylene glycol and electroporation increased loading efficiency. In the A/J mice vaccinated with fusion cells modified with the LacZ gene (fusion/LacZ), IFN-gamma production and CTL activity increased significantly compared with that of DCs/LacZ, C1300/LacZ, or a mixture of the two (mixture/LacZ). With the transduction of IL-12 and IL-18 genes into the fusion cells (fusion/IL-12/IL-18), the level of IFN-gamma increased more than five times that of other fusion groups. In addition, NK cell activity and CTL activity increased significantly compared with that of mixture/LacZ, fusion/LacZ, DC/LacZ, or C1300/LacZ. In the protective and therapeutic studies of fusion cell vaccine, mice vaccinated with fusion/LacZ, fusion/IL-12, fusion/IL-18, or fusion/IL-12/IL-18 showed a significant decrease in liver metastasis and a significant increase in survival compared with mice given a mixture/LacZ, DCs/LacZ, or C1300/LacZ. In particular, the mice receiving fusion/IL-12/IL-18 vaccine showed a complete protective effect and the highest therapeutic effects. The present study investigates the improved loading efficiency of fusion cells and suggests that the introduction of IL-12 and IL-18 genes can induce extremely strong protective and therapeutic effects on liver metastasis of neuroblastoma.

[Fusion vaccine therapy by IL-2-gene-transduced dendritic cells and tumor cells].

We evaluated the usefulness of fusion vaccine prepared from IL-2-gene-transduced splenic dendritic cells (DCs) and fibrosarcoma tumor cells (QRsP) in treating of lung metastasis. The IL-2 or LacZ gene was transferred into spleen-derived DCs using an adenoviral vector. Irradiated QRsP tumor cells were fused with IL-2 gene transduced DCs (fusion/IL-2) or LacZ gene transduced DCs (fusion/LacZ) by polyethyleneglycol. These fusion cells expressed major histocompatibility complex (MHC) class I and MHC class II, CD86, CD11c and CD8alpha. IFN-gamma and cytotoxic T lymphocyte (CTL) activity of splenic lymphocytes in mice vaccinated with fusion cells increased significantly as compared with those of DC or tumor cells vaccinated mice. CTL levels in fusion/IL-2-vaccinated mice were higher than that in fusion/LacZ-vaccinated mice. The number of lung metastasis in the fusion/IL-2 or fusion/LacZ-vaccineatd mice was significantly lower than that in mice vaccinated with DCs, tumor or PBS. The introduction of the IL-2 gene into fusion cells produced more potent therapeutic effects. Our results suggest that the fusion cells prepared from IL-2 gene transduced spleen derived DCs and tumor cells have the ability to induce therapeutic effect against lung metastasis.

Successful treatment of ruptured hepatocellular carcinoma with intraperitoneal injection of OK-432.

We report a 51-year-old man with a ruptured hepatocellular carcinoma (HCC). He was admitted to the hospital with abdominal pain and distension. Imaging studies revealed massive ascites, liver cirrhosis, and a 3-cm tumor at the inferior edge of the medial segment of the liver, with adhesions to the greater omentum. Abdominal paracentesis showed bloody ascites, and the patient was diagnosed with a ruptured HCC. OK-432, an immunomodulatory agent prepared from an attenuated strain of Streptococcus pyogenes, was injected (10 KE) into the peritoneal cavity four times within 1 week; the massive ascites disappeared, and the serum alpha-fetoprotein (AFP) level decreased to within the normal limits. Afterwards, he underwent a curative operation for HCC. His postoperative course was uneventful and he was discharged from the hospital on the twenty-second postoperative day. He had shown no evidence of recurrence or metastases at the time he died of hepatic failure related to alcohol abuse 9 months after the operation.
