A case of nodular gastritis progression to autoimmune gastritis after 10 years of Helicobacter pylori eradication.

A 61-year-old female patient underwent upper gastrointestinal endoscopy, which confirmed the presence of Helicobacter pylori (H. pylori)-positive nodular gastritis (NG). Routine upper gastrointestinal endoscopy after H. pylori eradication revealed atrophic changes of the corpus, having gradually progressed over the 10 years after successful eradication. Serological and biopsy specimen examination showed hypergastrinemia (1200 pg/mL), positive anti-parietal cell antibody (with a titer of more 160), and endocrine cell micronests after 11 years of H. pylori eradication. The patient was diagnosed with autoimmune gastritis (AIG) based on endoscopic, serological, and histological findings. This is the first report of AIG diagnosed in a patient with NG over a long period of time after H. pylori eradication.

Two Cases of Acute Gastric Mucosal Lesions Due to Helicobacter pylori Infection Confirmed to be Transient Infection.

Two adult cases of acute gastric mucosal lesions (AGML) caused by Helicobacter pylori infection were confirmed by spontaneous eradication during the follow-up period. The clinical course of the initial infection by H. pylori in adults with AGML remains unclear, whether it is transient or progresses to a persistent infection. In these two reported cases, gastric biopsies at the time of the onset revealed the presence of H. pylori; however, serum H. pylori antibodies performed at the same time were negative. Retesting for H. pylori serum antibody, after six months in one and after two months in the other, was negative, confirming spontaneous eradication.

Combination of type IV collagen 7S, albumin concentrations, and platelet count predicts prognosis of non-alcoholic fatty liver disease.

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease and affects approximately 25% of the general global adult population. The prognosis of NAFLD patients with advanced liver fibrosis is known to be poor. It is difficult to assess disease progression in all patients with NAFLD; thus, it is necessary to identify patients who will show poor prognosis. AIM: To investigate the efficacy of non-invasive biomarkers for predicting disease progression in patients with NAFLD. METHODS: We investigated biomarkers associated with mortality in patients with NAFLD who visited the Kawasaki Medical School General Medical Center from 1996 to 2018 and underwent liver biopsy and had been followed-up for > 1 year. Cumulative overall mortality and liver-related events during follow-up were calculated using the Kaplan-Meier analysis and compared using log-rank testing. We calculated the odds ratio and performed receiver operating characteristic curve analysis with logistic regression analysis to determine the optimal cut-off value with the highest prognostic ability. RESULTS: We enrolled 489 patients who were followed-up for a period of 1-22.2 years. In total, 13 patients died (2.7% of total patients enrolled); 7 patients died due to liver-related causes. Poor prognosis was associated with liver fibrosis on histological examination but not with inflammation or steatosis. Blood biomarkers associated with mortality were platelet counts, albumin levels, and type IV collagen 7S levels. The optimal cutoff index for predicting total mortality was a platelet count of 15 × 104/µL, albumin level of 3.5 g/dL, and type IV collagen 7S level of 5 mg/dL. In particular, only one-factor patients with NAFLD presenting with platelet counts ≤ 15 × 104/µL, albumin levels ≤ 3.5 g/dL, or type IV collagen 7S ≥ 5 mg/dL showed 5-year, 10-year, and 15-year survival rates of 99.7%, 98.3%, and 94%, respectively. However, patients with two factors had lower 5-year and 10-year survival rates of 98% and 43%, respectively. Similarly, patients with all three factors showed the lowest 5-year and 10-year survival rates of 53% and 26%, respectively. CONCLUSION: A combination of the three non-invasive biomarkers is a useful predictor of NAFLD prognosis and can help identify patients with NAFLD who are at a high risk of all-cause mortality.

Progression from Nonalcoholic Fatty Liver to Nonalcoholic Steatohepatitis Cirrhosis Confirmed by Liver Histology after 14 Years.

A 44-year-old patient progressed from nonalcoholic fatty liver (NAFL) to nonalcoholic steatohepatitis (NASH) cirrhosis. She was diagnosed with NAFL via a liver biopsy. At 56 years old, she was diagnosed with NASH stage 3 via a second liver biopsy. One year later, she was diagnosed with NASH cirrhosis via a third liver biopsy. This is the first study to report the gradual deterioration of liver histology shown via three liver biopsies and fibrosis markers in a patient who progressed from NAFL to NASH cirrhosis. Following menopause, it is necessary to be aware of the rapid development of liver fibrosis.

Differences in emergency endoscopy outcomes according to gastrointestinal bleeding location.

BACKGROUND AND AIM: With recent technological advances in the field of endoscopic hemostasis, the prognosis of patients with gastrointestinal (GI) bleeding has improved. However, few studies have reported on the clinical course of patients with GI bleeding. This study aimed to evaluate the differences in clinical outcomes of patients with lower GI bleeding (LGIB) compared with upper GI bleeding (UGIB) and the factors related to their prognosis. METHODS: Patients who had undergone emergency endoscopy for GI bleeding were retrospectively reviewed. The severity of GI bleeding was evaluated using the Glasgow-Blatchford (GB), AIMS65, and NOBLADS scores. Patients in whom obvious GI bleeding relapsed and/or iron deficiency anemia persisted after emergency endoscopy were considered to exhibit rebleeding. RESULTS: We reviewed 1697 consecutive patients and divided them into UGIB (1054 patients) and LGIB (643 patients) groups. The proportion of patients with rebleeding was significantly greater in the UGIB group than in the LGIB group; the mortality rate was significantly higher in the UGIB group than in the LGIB group. Multivariate analysis showed that a GB score ≥12 and an AIMS65 score ≥2 were significantly associated with rebleeding in the UGIB group, whereas a NOBLADS score ≥4 was significantly associated with rebleeding in the LGIB group. Notably, the influence of emergency endoscopy differed according to GI bleeding location. CONCLUSIONS: The clinical course was significantly worse in patients with UGIB than in patients with LGIB. The influence of emergency endoscopy differed according to GI bleeding location.

Gastric Hyperplastic Polyps after Argon Plasma Coagulation for Gastric Antral Vascular Ectasia in Patients with Liver Cirrhosis: A Case Suggesting the "Gastrin Link Theory".

We herein report a case of gastric hyperplastic polyps after argon plasma coagulation (APC) for gastric antral vascular ectasia (GAVE) in the antrum of a 65-year-old man with liver cirrhosis and hypergastrinemia induced by long-term proton pump inhibitor (PPI) use. Two years after APC therapy, endoscopy demonstrated multiple gastric polyps in the antrum and angle. A gastric polyp biopsy indicated foveolar epithelium hyperplasia, which was diagnosed as gastric hyperplastic polyps. One year after switching to an H2 blocker antagonist, endoscopy revealed that the polyps and GAVE had disappeared, with normal gastrin levels suggesting that PPI-induced hypergastrinemia had caused gastric hyperplastic polyps after APC therapy, and the polyps had disappeared after discontinuing PPIs.

Fatty Liver, and Not Visceral Fat, Is More Associated with Liver Fibrosis and Diabetes in Non-Obese Japanese Individuals: A Cross-Sectional Study.

Asians are known to be more likely than Westerners to develop fatty liver and lifestyle-related diseases in spite of their weight. However, the relationship between fat accumulation and lifestyle-related diseases in non-obese Asians is unknown. Therefore, this study aimed to analyze visceral fat and hepatic fat in participants with a normal body mass index (BMI) and examine their characteristics during a medical checkup. This cross-sectional study was conducted on 663 of 1142 patients who underwent abdominal ultrasonography and who had an alcohol intake (converted to ethanol) of <30 g/day for males and <20 g/day for females and a BMI of <25 kg/m2 during a health checkup. Participants were classified into four groups: group A, visceral fat accumulation (VFA) (-) and fatty liver (FL) (-) (n = 549); group B, VFA (+) and FL (-) (n = 32); group C, VFA (-) and FL (+) (n = 58); and group D, VFA (+) and FL (+) (n = 24). The frequencies of lifestyle-related disease complications, liver function tests, and liver fibrosis were evaluated among the four groups. Compared with group A (control), groups B, C, and D had a higher number of males, BMI, abdominal circumference, ALT, AST, γ-GTP, triglyceride, uric acid, fasting blood sugar levels, and incidence of hyperlipidemia. Groups C and D had higher ALT, HbA1c, cholinesterase, and triglyceride levels, FIB4 index, and the number of patients with diabetes mellitus (DM) than groups A and B; however, there was no difference between groups A and B. FL is a risk factor of DM and liver fibrosis in non-obese Japanese individuals; however, VFA only is not a risk factor of DM and liver fibrosis.

High Prevalence of Autoimmune Gastritis in Patients with Nonalcoholic Steatohepatitis.

Objective To evaluate the prevalence of autoimmune gastritis in patients with histologically proven nonalcoholic steatohepatitis (NASH). Methods A total of 33 patients with NASH and 143 patients with chronic liver disease (66, 24, 22, 10, 1, and 21 patients with hepatitis C, hepatitis B, autoimmune hepatitis/primary biliary cholangitis, non-B/non-C hepatitis, fatty liver, and alcoholic disease, respectively) who underwent upper gastrointestinal endoscopy between January 2013 and August 2016 were retrospectively assessed to determine the prevalence of autoimmune gastritis. The clinical characteristics of these patients with NASH and autoimmune gastritis were examined, and the clinical characteristic and biomarkers were compared between patients with NASH with and without autoimmune gastritis. Results Six of the 33 patients with NASH (19.4%) were diagnosed with autoimmune gastritis. The prevalence of autoimmune gastritis was higher in patients with NASH than in those with other chronic liver diseases [4/143 (2.8%), p=0.002]. All six patients with NASH and autoimmune gastritis exhibited high serum gastrin levels; five of the patients were positive for anti-parietal cell antibodies, and one was negative for anti-parietal cell antibodies but positive for intrinsic factor antibody. Furthermore, 1 patient presented with iron-deficiency anemia (hemoglobin <11 g/dL), but none developed pernicious anemia. Endocrine cell micronests were found in four patients. Patients with NASH and autoimmune gastritis tended to be older with lower ferritin levels than the other patients. Conclusion The prevalence of NASH with concomitant autoimmune gastritis was high, highlighting the need for upper endoscopy for the diagnosis of autoimmune gastritis and gastric malignancies.

Gastroduodenal ulcer bleeding in elderly patients on low dose aspirin therapy.

AIM: To determine the clinical characteristics of elderly patients of hemorrhagic gastroduodenal ulcer on low-dose aspirin (LDA) therapy. METHODS: A total of 1105 patients with hemorrhagic gastroduodenal ulcer treated in our hospital between January 2000 and March 2016 were grouped by age and drugs used, and these groups were compared in several factors. These groups were compared in terms of length of hospital stay, presence/absence of hemoglobin (Hb) decrease, presence/absence of blood transfusion, Forrest I, percentage of Helicobacter pylori infection, presence/absence of underlying disease, and percentage of severe cases. RESULTS: The percentage of blood transfusion (62.6% vs 47.7 %, P < 0.001), Hb decrease (53.8% vs 40.8%, P < 0.001), and the length of hospital stay (23.5 d vs 16.7 d, P < 0.001) were significantly greater in those on drug therapy. The percentage of blood transfusion (65.3% vs 47.8%, P < 0.001), Hb decrease (54.2% vs 42.1%, P < 0.001), and length of hospital stay (23.3 d vs 17.5 d, P < 0.001) were significantly greater in the elderly. In comparison with the LDA monotherapy group, the percentage of severe cases was significantly higher in the LDA combination therapy group when elderly patients were concerned (16.1% vs 34.0%, P = 0.030). Meanwhile, among those on LDA monotherapy, there was no significant difference between elderly and non-elderly (16.1% vs 16.0%, P = 0.985). CONCLUSION: A combination of LDA with antithrombotic drugs or non-steroidal anti-inflammatory drugs (NSAIDs) contributes to aggravation. And advanced age is not an aggravating factor when LDA monotherapy is used.

Recent trends in the occurrence of bleeding gastric and duodenal ulcers under the Japanese evidence-based clinical practice guideline for peptic ulcer disease.

BACKGROUND: Gastrointestinal hemorrhage occurs frequently. We reviewed the tendency of occurrence of bleeding gastric and duodenal ulcers and their association with antithrombotic therapy before and after the widespread use of Evidence-Based Clinical Practice Guidelines for Peptic Ulcer 2009 (1st edition), which was published to improve treatment outcomes and prevent peptic ulcers. METHODS: The study enrolled 1105 patients with bleeding gastric and duodenal ulcers treated at our hospital between January 2000 and March 2016. They were divided into the preguideline group (807 patients treated between January 2000 and December 2010) and the postguideline group (298 patients treated between January 2011 and March 2016). The use of medications, severity, the incidence of Helicobacter pylori infection, the presence of any underlying disease, and other factors were compared between the pre- and postguideline groups. RESULTS: The number of patients receiving antithrombotic therapy was slightly higher in the postguideline group without a significant difference (P = 0.50). The incidence of H. pylori infection was significantly lower in the postguideline group (P < 0.001). The rate of premedication with a proton pump inhibitor (PPI) and the rate of severe ulcers were significantly higher in the postguideline group (P = 0.001 and P < 0.001, respectively). The rebleeding rate showed no significant difference, whereas the recurrence rate was significantly higher in the postguideline group (P = 0.041). CONCLUSIONS: The major cause of hemorrhagic gastroduodenal ulcers seems to be shifting from H. pylori infection to the administration of drugs with gastrointestinal risk. Antithrombotic therapy tends to be associated with severe ulcers but without statistical significance.

Gastric Adenocarcinoma of the Fundic Gland Type after Endoscopic Therapy for Metachronous Gastric Cancer.

A 78-year-old man underwent endoscopic submucosal dissection (ESD) for early gastric adenocarcinoma twice in 2009 and 2014. Between the procedures, he successfully completed Helicobacter pylori eradication therapy. In May 2015, upper endoscopy screening showed two elevated lesions on the gastric fundus, and en bloc resection by ESD was performed. We histopathologically diagnosed the patient to have gastric adenocarcinoma of the fundic gland type. In this case, the two lesions of gastric adenocarcinoma of the fundic gland type multifocally developed after ESD for metachronous gastric tubular adenocarcinoma. Furthermore, they appeared in the gastric fundus, where atrophy had been improved due to eradication therapy.

Clinical importance of colonoscopy in patients with gastric neoplasm undergoing endoscopic submucosal dissection.

AIM: To evaluate the usefulness of total colonoscopy (TCS) for patients undergoing gastric endoscopic submucosal dissection (ESD) and to assess risk factors for colorectal neoplasms. METHODS: Of the 263 patients who underwent ESD at our department between May 2010 and December 2013, 172 patients undergoing TCS during a one-year period before and after ESD were targeted. After excluding patients with a history of surgery or endoscopic therapy for colorectal neoplasms, 158 patients were analyzed. Of the 868 asymptomatic patients who underwent TCS during the same period because of positive fecal immunochemical test (FIT) results, 158 patients with no history of either surgery or endoscopic therapy for colorectal neoplasms who were matched for age and sex served as the control group for comparison. RESULTS: TCS revealed adenoma less than 10 mm in 53 patients (33.6%), advanced adenoma in 17 (10.8%), early colorectal cancer in 5 (3.2%), and advanced colorectal cancer in 4 (2.5%). When the presence or absence of adenoma less than 10 mm, advanced adenoma, and colorectal cancer and the number of adenomas were compared between patients undergoing ESD and FIT-positive patients, there were no statistically significant differences in any of the parameters assessed. The patients undergoing ESD appeared to have the same risk of colorectal neoplasms as the FIT-positive patients. Colorectal neoplasms were clearly more common in men than in women (P = 0.031). Advanced adenoma and cancer were significantly more frequent in patients with at least two of the following conditions: hypertension, dyslipidemia, and diabetes mellitus (P = 0.019). CONCLUSION: In patients undergoing gastric ESD, TCS appears to be important for detecting synchronous double neoplasms. Advanced adenoma and cancer were more common in patients with at least two of the following conditions: hypertension, dyslipidemia, and diabetes mellitus. Caution is therefore especially warranted in patients with these risk factors.

[Coronary Artery Spasm during Anesthesia: Discussion of Cases Leading to Circulatory Collapse through 51 Reports of the Published Literature].

BACKGROUND: Perioperative coronary artery spasm (GAS) is one of the serious complications leading to circulatory collapse. Here we retrospectively examined the impact of CAS and discussed its prevention strate- gies. METHODS: Reports of intraoperative CAS were iden- tified by using the PubMed and by manually searching the Journal of Japan Society for Clinical Anesthesia (2001-2015). Analyses were performed on 51 patients who developed CAS and had had no history of isch- emic heart disease. RESULTS: Of the 51 analyzed patients, 19 developed circulatory collapse. In these patients, the rate of early administration of a sufficient dose of a coronary vasodi- lator was low, and they tended to have prolonged and/ or recurrent attacks. Among them, two patients may have had a problem due to the dosage and/or admin- istration method for coronary vasodilator, despite early administration. In addition, we found that a combina- tion of general anesthesia and epidural block may have contributed to the collapse. In three cases, it was diffi- cult to identify the predictors of circulatory collapse. CONCLUSIONS: Awareness of CAS and vigilant moni- toring are crucial for preventing circulatory collapse. When a transient ST-segment change indicates possi- ble CAS, adequate dosages of a coronary vasodilator should be promptly administered.

[General Anesthesia for the Thoracoscopic Lung Resection Surgery in 12 Very Elderly Patients above 85 Years of Age].

We investigated perioperative management and clinical outcome of 12 patients who were 85 years old or older and received video-assisted thoracic surgery under general anesthesia. Although all the patients had preoperative respiratory complications or cardiovascular complications, they were discharged without any additional respiratory assistance such as home oxygen therapy. Our observation suggests that it is important to evaluate the indication of anesthesia from their daily activities and pulmonary function test even if they are oldest-old. If the patient demonstrates good physical function, he or she should not be excluded from anesthesia.

Assessment of left ventricle preload by transthoracic echocardiography: an easy task?

In sicker hearts, right atrial pressure (an estimation of right ventricle preload) are not equivalent to left atrial pressure (an estimation of left ventricle preload). Both right and left atrial pressures are frequently estimated using invasive techniques and also transthoracic echocardiography. While right atrial pressure is easy to obtain with transthoracic echocardiography, the assessment of left ventricle preload or filling pressures is not simple. In relation to the study of Sasai et al. (J Intensive Care 2(1):58, 2014), this paper discusses in a succinct manner how to think and assess the left ventricle preload by transthoracic echocardiography.

Comparison of the usefulness of endoscopic papillary large-balloon dilation with endoscopic sphincterotomy for large and multiple common bile duct stones.

BACKGROUND: Endoscopic sphincterotomy (EST) is currently recognized as the primary endoscopic treatment for common bile duct stones. However, it is difficult to remove multiple (≥ 3) or large (≥ 15 mm) common bile duct stones with EST alone. Recently, EST plus endoscopic papillary large-balloon dilation (EPLBD) was reported to be an effective treatment for such bile duct stones. We compared the results of EST and EST + EPLBD for multiple (≥ 3) or large (≥ 15 mm) stones that were difficult to treat using EST alone. We also compared the complication rates between the techniques. METHODS: Seventy patients with large (largest diameter, ≥ 15 mm) or ≥ 3 common bile duct stones treated in our department between April 2010 and March 2013 underwent EST + EPLBD (n = 34) or EST alone (n = 36). We compared final successful stone removal rates, rates of successful stone removal in the first session, procedure times, status of concurrent mechanical lithotripsy (ML), and complications between the EST + EPLBD and EST groups. RESULTS: The rates of final successful stone removal were similar between the two groups (EST + EPLBD: 100 % vs. EST: 89 %; p = 0.115). The rate of successful stone removal in the first session was significantly higher in the EST + EPLBD group (EST + EPLBD: 88 % vs. EST: 56 %; p = 0.03). Moreover, the procedure time was significantly shorter (EST + EPLBD: 42 min vs. EST: 67 min; p = 0.011) and the rate of ML use was significantly lower in the EST + EPLBD group (EST + EPLBD: 50 % vs. EST: 94 %; p < 0.001). Complications like pancreatitis and bleeding occurred in three patients in the EST + EPLBD group and in 10 patients in the EST group, but the differences were not statistically significant (EST + EPLBD: 9 % vs. EST: 25 %; p = 0.112). CONCLUSIONS: Our results suggest that EST + EPLBD is an effective therapy for patients with difficult-to-treat multiple or large common bile duct stones, because it requires fewer sessions and shorter operative times than EST alone.

Relationship between the degree of endoscopic atrophy of the gastric mucosa and carcinogenic risk.

BACKGROUND: The relationship between Helicobacter pylori infection and gastric cancer has been demonstrated, and the risk of gastric cancer occurrence is known to increase with the progression of atrophic changes associated with chronic gastritis. Endoscopic evaluation of the degree and extent of atrophy of the gastric mucosa is a simple and very important means of identifying a group at high risk for gastric cancer. This study aimed to clarify the carcinogenic risk in relation to the degree of atrophy. METHODS: A total of 27,777 patients (272 with early gastric cancer and 135 with advanced gastric cancer) were included in this study. Endoscopically evaluated atrophy of the gastric mucosa was classified as C-0 to O-3 according to the Kimura and Takemoto classification system. RESULTS: The cancer detection rate in relation to the degree of gastric mucosal atrophy was 0.04% (2/4,183 patients) for C-0, 0% (0/4,506) for C-1, 0.25% (9/3,660) for C-2, 0.71% (21/2,960) for C-3, 1.32% (75/5,684) for O-1, 3.70% (140/3,780) for O-2 and 5.33% (160/3,004) for O-3. As to the proportions of differentiated and undifferentiated cancers, the latter were relatively frequent in the C-0 to C-2 groups, but differentiated cancers became predominant as atrophy progressed. On the other hand, the number of both differentiated and undifferentiated cancers detected increased as gastric mucosal atrophy progressed. In addition, open-type atrophy was found in 29 (96.7%) of 30 patients with synchronous multiple gastric cancers and in all 20 patients with metachronous multiple gastric cancers. CONCLUSION: Endoscopic evaluation of gastric mucosal atrophy can provide a simple and reliable predictive index for both current and future carcinogenic risk.

A second-look endoscopy may not reduce the bleeding after endoscopic submucosal dissection for gastric epithelial neoplasm.

BACKGROUND: Gastric endoscopic submucosal dissection (ESD) has gradually come to be recommended as the optimal treatment for early gastric cancer; however, one of the primary issues is postoperative bleeding. Although second-look endoscopy is conventionally performed to reduce the risk of postoperative bleeding, its benefit has not yet been clearly elucidated. The objective of this study was to elucidate the benefit of second-look endoscopy. METHODS: A total of 459 lesions in patients were underwent gastric ESD from May 2004 to April 2013 at our hospital were included in the analysis. The patients were divided into those who had bleeding within 24 hours after ESD (immediate bleeding) and those in whom bleeding occurred 24 hours or more after the procedure (delayed bleeding); the underlying disease, age, lesion site, diameter of the resected specimen, and lesion diameter were analyzed to identify the risk factors for postoperative bleeding after ESD. RESULTS: Post-ESD immediate or delayed bleeding occurred in 23 of the 459 cases (5.0%). Second-look endoscopy was performed in 210 of 447 cases (47.0%) excluding 12 cases with immediate bleeding; in the remaining 237 of the 447 cases (53.0%), it was not performed. Post-ESD delayed bleeding occurred in 6 of the 210 cases (2.9%) and 5 of the 237 cases (2.1%), with no statistically significant difference between the two groups. Overall, the following factors were identified as the risk factors for postoperative bleeding: young age (P = 0.005), lesions in the L segment (P = 0.042), and large size of the resected specimen (P = 0.005). The risk factors identified in the immediate bleeding group were lesions in the L segment (P = 0.032), large size of the resected specimen (P < 0.001), and large tumor size (P = 0.011), and those in the delayed bleeding group were young age (P = 0.013) and concomitant renal disease (P = 0.011). CONCLUSIONS: The results of this study suggest that second-look endoscopy after gastric ESD may not be useful for preventing postoperative bleeding.

Reliability of central venous pressure to assess left ventricular preload for fluid resuscitation in patients with septic shock.

BACKGROUND: Initial fluid resuscitation is an important hemodynamic therapy in patients with septic shock. The Surviving Sepsis Campaign Guidelines recommend fluid resuscitation with volume loading according to central venous pressure (CVP). However, patients with septic shock often develop a transient decrease in cardiac function; thus, it may be inappropriate to use CVP as a reliable marker for fluid management. METHODS: We evaluated 40 adult patients with septic shock secondary to intra-abdominal infection who received active treatment and were monitored using transthoracic echocardiography (TTE) and CVP for 2 days after admission to our intensive care unit (ICU). We measured left ventricular end-diastolic diameter (LVEDD), left atrial diameter (LAD), and the pressure gradient of tricuspid regurgitation (TR∆P). The shock status was treated with volume loading and inotrope/vasopressor administration according to the TTE findings. We assessed left ventricular fractional shortening (LVFS) as an index of left ventricular contractility and TR∆P as an index of right ventricular afterload and then examined the correlation between CVP and LVEDD/LAD/TR∆P. RESULTS: LVFS decreased to ≤30% in 42.5% and 27.5% of patients with septic shock, and severe left ventricular dysfunction with LVFS ≤20% developed in 12.5% and 15.0% of patients on the first and second ICU days, respectively, despite the use of inotropes/vasopressors. Mild pulmonary hypertension as indicated by TR∆P ≥30 mmHg was present in 27.5% and 30.0% of patients on their first and second ICU days, respectively. There was no significant correlation between CVP and LVEDD/LAD/TR∆P. The hospital mortality rate in this study was 10.0%, although the predicted mortality based on the Acute Physiology and Chronic Health Evaluation II score was 58.7%. CONCLUSIONS: Our results suggest that CVP is not a reliable marker of left ventricular preload for fluid management during the initial phase of septic shock. Assessment of left ventricular preload, right ventricular overload, and left ventricular contractility using TTE seems to be more informative than the measurement of CVP for fluid resuscitation since some patients developed left ventricular dysfunction and/or right ventricular overload.

[General anesthesia for lung resection in 7 patients with forced expiratory volume in 1 second of less than 1l].

Preoperative forced expiratory volume in 1 second less than 1 l is a risk factor for anesthesia. We report perioperative management and prognosis of 7 patients with restricted lung function who underwent lung resection under general anesthesia. We assessed the patients preoperatively from the point of view of heart-lung functions such as predicted postoperative forced expiratory volume in 1 second greater than 0.8 l, an ability of walking on the level for more than 5 minutes at his own speed without a rest, presence of hypercapnia, and degree of pulmonary hypertension. One patient was extubated on the first postoperative day because of an asthmatic attack, whereas the remaining 6 patients were extubated in the operating room. Although 1 patient developed postoperative complications of lung air leakage and pneumonia, he recovered with conservative therapy. All patients were discharged without any sequela. We were able to manage high-risk patients with limited lung functions successfully during the perioperative period without serious complications.
