[Function of the Puborectalis Muscle in Patients with or without Fecal Incontinence Three Years after Low Anterior Resection for Lower Rectal Cancer].

To clarify the function of the puborectalis muscle(PM)in fecal incontinence(FI)prevention after low anterior resection (LAR)for lower rectal cancer(LRC), PM function at 3 years after LAR was studied. A total of 29 patients aged 40-79 years (19 men and 10 women, mean age: 63.9 years)who underwent LAR for LRC were enrolled in the present study. Based on the presence of postoperative FI, these patients were divided into 2 groups[group A: patients with FI(n=13), 11 men and 2 women aged 43-75 years(mean age: 64.8 years)and group B: patients without FI(continence, n=16), 8 men and 8 women aged 41-79 years(mean age: 62.9 years)]. These groups were compared with group C of control subjects[n=38; 28 men and 10 women aged 42-76 years(mean age: 64.5 years)]. Magnetic stimulation at the S2-4 sacral levels has been shown to activate the sacral motor nerve(SMN)root of the cauda equina. SMN latency(SMNL)was determined on the right, left, and posterior sides of the upper anal canal. FI after LAR was also evaluated using the Wexner score(WS), with a score of 8 or more being associated with FI according to our data. All patients had pathological Stage Ⅰ disease(19 patients: T1, N0, M0; 10 patients: T2, N0, M0). Group A had a larger proportion of men than group B(p<0.1). The distance of anastomosis from the anal verge(DAAV)was significantly shorter in group A(2.2±1.2 cm)than in group B(4.6 ±1.3 cm)(p<0.001). Regarding WS of group A, 23.1% patients had a score of 8-10(mean: 9.0), 53.8% of 11-15 (mean: 13.4), and 30.7% of 16-20(mean: 17.0). All patients in group A(WS: 8 or more)were incontinent. In contrast, all patients in groups B(WS: 0)and C(WS: 0)were continent. Patients with preoperative defecation ability(WS: 0)were also continent. As for SMNL on the right(9 o'clock), left(15 o'clock), and posterior(18 o'clock)sides of the PM located in the upper anal canal, conduction delay was significantly longer in group A(8.4±0.6 ms, 8.2±1.9 ms, and 8.3±0.9 ms, respectively)than in groups B(4.4±0.5 ms, 4.3±0.7 ms, and 4.4±0.9 ms, respectively)and C(4.1±0.5 ms, 4.0±0.5 ms, and 4.2±0.7 ms, respectively)(p<0.001, all). FI after LAR with a short DAAV, especially in men, may cause PM dysfunction due to operative damage of the SMN.

[Relationships Gastric Stasis in the Remnant Stomach and Interdigestive Migrating Motor Complex in Patients after Pylorus-Preserving Gastrectomy for Early Gastric Cancer].

The demerit of pylorus-preserving gastrectomy(PPG)is the postprandial abdominal fullness(PAF)with gastric stasis in the remnant stomach(GSRS). We investigated the relationship between clinical findings and GSRS, and between GSRS and interdigestive migrating motor complex(IMMC)in PPG patients. A total of 30 patients(17 men and 13 women, mean age of 62.3 years)after PPG for early gastric cancer(Billroth Ⅰ)were divided into 2 groups(group A; 18 patients with GSRS, group B; 12 patients without GSRS). The relationship between GSRS including clinical findings and IMMC was studied from 1.5 to 3 years after operation. A catheter equipped with a micro-tip force transducer was inserted transnassally into the remnant stomach and duodenum in a supine position, and the IMMC was studied. All patients were Stage ⅠA(mucosal cancer, no lymph node metastasis, no distant metastasis). The remnant stomach was 1/3 compared with stomach size before operation. The length of the antral cuff in group A(1.5±0.2 cm)was significantly shorter than group B(3.2±0.3 cm)(p =0.0004). Appetite was significantly recognized in group B compared with group A(p=0.0067). PAF was significantly recognized in group A compared with group B(p=0.0001). Reflux esophagitis was found in group A more than group B. Early dumping syndroms did not found significant differences in both groups. In endoscopic esophagogastric finding of the remnant stomch, gastritis with GSRS was significantly found in group A compared with group B(p=0.0001). The IMMC was significantly recognized in group B compared with group A(p<0.0001). The occurrence of the PAF due to the GSRS may be caused by abscens of the IMMC.

[Role of Pudendal Sensory Nerve in Patients with or without Fecal Incontinence after Low Anterior Resection for Lower Rectal Cancer].

To clarify the pudendal sensory nerve(PSN)play in preventing fecal incontinence(FI)after low anterior resection(LAR) for lower rectal cancer, the PSN function was studied at 6 months after LAR. A total of 36 patients aged 42.0 to 79.0 years (23 males and 13 females with a mean age of 62.0 years)who underwent LAR for laparoscopic radical cystectomy(LRC) were enrolled in the present study. Based on postoperative F1, these patients were divided into 2 groups[group A; patients with FI(n=12), group B; patients without FI(continence, n=24)]. These were compared with group C(n=32, control subjects, 18 males and 14 females aged 40.0 to 76.0 years with a mean age of 61.8 years). Anal mucosal electric sensitivity (AMES)threshold was measured [at the upper 1 cm oral side from dentate line(DL); a, DL; b, and lower zones 1 cm anal side from DL; c]. FI after LAR was also evaluated by the Wexner score(WS). All patients were pathological Stage Ⅰ(25 patients: T1, N0, M0; 11 patients: T2, N0, M0). Group A had a significantly larger proportion of males than group B(p< 0.05). The distance of anastomosis from anal verge(DAAV)in group A(2.4±1.8 cm)was significantly shorter than in group B(4.4±0.9 cm)(p<0.001). WS from 6 to 10 comprised 25.0% of group A, 11 to 15 comprised 50.0%, and 16 to 20 comprised 25.0%. All patients in group A(WS; 8 or more)were incontinent. In contrast, all patients in group B(WS; 0) and C(WS; 0)were continent. Patients in pre-operative defecation(WS; 0)were also continent. On the AMES(a, b, c), sensitivity of patients in group A(6.4±1.1, 5.1±0.5, 4.9±0.6 mA)was significantly higher than in groups B(2.6±0.5, 2.4 ±0.4, 2.5±0.6 mA)and C(2.3±0.4, 2.1±0.4, 2.3±0.5 mA)at all zones(p<0.001). FI after LAR with a short DAAV, especially male, may be PSN dysfunction due to operative damage of PSN.

Supernormal Antithrombin Activity Is an Independent Predictor of In-Hospital Mortality in Patients With Sepsis: A Retrospective Observational Study.

Supernormal antithrombin (AT) activity is rare in patients with sepsis. This study compared mortality rate of patients with sepsis and supernormal AT activity with that of other patients. This retrospective study included patients with sepsis from 42 intensive care units (ICUs) in Japan. Patients were included if their AT activity was measured on ICU admission, and if they did not receive AT concentrate. They were categorized into low, normal, and supernormal with respective AT activity of ≤70%, >70% to ≤100%, and >100%. The primary outcome was hospital in-patient mortality. Nonlinear regression analysis showed that mortality risk gradually increased with AT activity in the supernormal range, but without statistical significance. Survival rate was significantly lower in low (67%) and supernormal (57%) AT groups than in the normal AT group (79%; P < .001 and P = .008, respectively). After adjusting for disease severity and AT activity on day 2, supernormal AT activity was the only independent predictor of mortality. Sepsis with supernormal AT activity associated with high mortality, independent of disease severity, might be a predictor of in-hospital mortality.

[Function of Pudendal Motor Nerve in Patients with or Without Fecal Incontinence after Low Anterior Resection for Lower Rectal Cancer].

To clarify the pudendal motor nerve(PMN)play in preventing fecal incontinence(FI)after low anterior resection(LAR) for lower rectal cancer, the PMN function was studied at early postoperative period after LAR. A total of 30 patients aged 43 to 78 years (21 men and 9 women with a mean age of 62.4 years) who underwent LAR for LRC were enrolled in the present study. Based on postoperative FI, these patients were divided into 2 groups(group A: patients with FI[n=10], group B: patients without FI[continence, n=20]). These were compared with group C(n=28, control subjects, 18 men and 10 women aged 46 to 76 years with a mean age of 60.2 years). Magnetic stimulation at the S2-4 sacral levels has been shown to activate the PMN root of the cauda equina. PMN latency(PMNL)at posterior sides of the anal canal was studied. FI after LAR was also evaluated by the Wexner score(WS). All patients were pathological Stage Ⅰ(20 patients: T1, N0, M0; 10 patients: T2, N0, M0). Group A had a significantly larger proportion of men than group B(p<0.05). The distance of anastomosis from anal verge(DAAV)in group A(2.4±1.7 cm)was significantly shorter than in group B(4.4±0.9 cm)(p< 0.001). WS from 8 to 10(mean: 9.25)comprised 20.0% of group A, 11 to 15(mean: 13.5)50.0%, and 16 to 20(mean: 18.5)comprised 30.0%. All patients in group A(WS: 8 or more)were incontinent. In contrast, all patients in group B(WS: 0)and C(WS: 0)were continent. Patients in pre-operative defecation(WS: 0)were also continent. As for PMNL, the conduction delay in group A(7.9±0.9 ms)was significantly longer than in groups B(4.1±0.6 ms)and C(3.9±0.3 ms) (p<0.001, respectively). FI after LAR with a short DAAV may be EAS dysfunction due to damage of PMN.

[A Case of Local Recurrence of Descending Colon Cancer with Ileus Obstruction and Lung, Liver and Brain Metastasis].

We report a 50-year-old man with local recurrence of descending colon cancer with ileus obstruction and brain metastasis, 2 years 6 months after initial resection due to perforation of descending colon cancer(Hartmann procedure, D2 lymph node resection, Stage II, tub2). He complained of left upper abdominal pain and abdominal fullness. He also complained of paresis of the right upper extremity and of experiencing convulsions 1 month before admission. He was diagnosed with local recurrence of descending colon cancer, based on findings of contrast radiography and the presence of colonic fiber. We subsequently performed transanal decompression as a bridge to surgery and performed partial resection of the local recurrence in the anastomosis at the descending colon and ileum involved with the cancer 2 weeks after decompression. In addition, multiple lung and liver metastases, and solitary brain metastasis(2.5 cm in size located in the left side of the parietal region) were detected by cerebral plain computed tomography. However, he refused both chemotherapy after surgery, as well as further surgery and/or radiation therapy for the brain metastasis. He desired to return to his home as soon as possible. In order to improve his quality of life(QOL), in-home treatment involving the best supportive care(BSC)conservative therapiesincluding, anticonvulsant and anti-intracranial hypertension drugs-were administered to prevent brain metastasis symptoms, such as paresis of the right upper extremities and convulsions. He was discharged from our hospital 14 days after surgery. Regrettably, he died due to bronchial asthma 75 days after palliative surgery in his home.

The Japanese Clinical Practice Guidelines for Management of Sepsis and Septic Shock 2016 (J-SSCG 2016).

BACKGROUND AND PURPOSE: The Japanese Clinical Practice Guidelines for Management of Sepsis and Septic Shock 2016 (J-SSCG 2016), a Japanese-specific set of clinical practice guidelines for sepsis and septic shock created jointly by the Japanese Society of Intensive Care Medicine and the Japanese Association for Acute Medicine, was first released in February 2017 and published in the Journal of JSICM, [2017; Volume 24 (supplement 2)] 10.3918/jsicm.24S0001 and Journal of Japanese Association for Acute Medicine [2017; Volume 28, (supplement 1)] http://onlinelibrary.wiley.com/doi/10.1002/jja2.2017.28.issue-S1/issuetoc.This abridged English edition of the J-SSCG 2016 was produced with permission from the Japanese Association of Acute Medicine and the Japanese Society for Intensive Care Medicine. METHODS: Members of the Japanese Society of Intensive Care Medicine and the Japanese Association for Acute Medicine were selected and organized into 19 committee members and 52 working group members. The guidelines were prepared in accordance with the Medical Information Network Distribution Service (Minds) creation procedures. The Academic Guidelines Promotion Team was organized to oversee and provide academic support to the respective activities allocated to each Guideline Creation Team. To improve quality assurance and workflow transparency, a mutual peer review system was established, and discussions within each team were open to the public. Public comments were collected once after the initial formulation of a clinical question (CQ) and twice during the review of the final draft. Recommendations were determined to have been adopted after obtaining support from a two-thirds (> 66.6%) majority vote of each of the 19 committee members. RESULTS: A total of 87 CQs were selected among 19 clinical areas, including pediatric topics and several other important areas not covered in the first edition of the Japanese guidelines (J-SSCG 2012). The approval rate obtained through committee voting, in addition to ratings of the strengths of the recommendation, and its supporting evidence were also added to each recommendation statement. We conducted meta-analyses for 29 CQs. Thirty-seven CQs contained recommendations in the form of an expert consensus due to insufficient evidence. No recommendations were provided for five CQs. CONCLUSIONS: Based on the evidence gathered, we were able to formulate Japanese-specific clinical practice guidelines that are tailored to the Japanese context in a highly transparent manner. These guidelines can easily be used not only by specialists, but also by non-specialists, general clinicians, nurses, pharmacists, clinical engineers, and other healthcare professionals.

[Postprandial Abdominal Fullness after Pylorus-Preserving Gastrectomy for Early Gastric Cancer].

To clarify the basis for postprandial abdominal fullness(PAF)in patients after pylorus-preserving gastrectomy(PPG), the authors investigated the relationship of PAF with postgastrectomy disorder(PGD)and gastric emptying function(GEF)in PPG patients. A total of 22 patients(14 men and 8 women, average age 64.8 years)were divided into 2 groups[Group A, PAF-positive(n=12); Group B, PAF-negative(n=10)]at 1 year after PPG for early gastric cancer. The relationships of PAF with PGD and GEF were examined. Length of the antral cuff(LAC)was significantly shorter in group A than in group B(p< 0.05). Appetite and food consumption per meal were significantly greater in group B than in group A(p<0.05 and p<0.01, respectively). Symptomatic reflux esophagitis(RE), early dumping syndrome, decreased percent body weight before illness, endoscopic RE, and endoscopic gastritis in the remnant stomach were more common in group A than in group B. Gastric stasis in the remnant stomach was significantly more common in group A than in group B(p=0.0071). GEF for solid food [time to 50%residual rate in the remnant stomach(minutes)and residual rate at 120 minutes in the remnant stomach(%)] in group A was significantly delayed compared with that in group B(p<0.001). Patients with PAF showed shorter LAC, delayed GEF for solid food, and worse postoperative quality of life(QOL), compared with those without PAF.

[Primary Undifferentiated Pleomorphic Sarcoma of the Ileum-A Case Report].

Undifferentiated pleomorphic sarcoma(UPS)of the small intestine is extremely rare and has a poor prognosis. We encountered a case of primary UPS of the ileum without metastatic lesions. The patient was a 44-year-old man who presented with the chief complaint of lower abdominal pain for 9 months. He also presented with anemia, hypoproteinemia, and a lower abdominal tumor about 10 cm in size. Abdominal CT with cystography showed an irregular solid tumor with compression of the cystic bladder. Based on a presumptive diagnosis of the retroperitoneal tumor, he underwent laparotomy. An irregular tumor, 9×8×5 cm in size, was observed in the ileum approximately 60 cm from the terminal ileum. There were no lymph node, peritoneal, or liver metastases. Partial excision of 30 cm of the ileum from 50 cm to 80 cm at the terminal ileum was performed. The final histological diagnosis was primary UPS(storiform pattern with fibroblast-like spindle cells). The patient was not administered adjuvant chemotherapy and was discharged on postoperative day 10. He is currently well without any evidence of recurrence for 2 years after the surgery.

Effectiveness of cadaver-based educational seminar for trauma surgery: skills retention after half-year follow-up.

Aim: In Japan, trauma surgery training remains insufficient, and on-the-job training has become increasingly difficult because of the decreasing number of severe trauma patients and the development of non-operative management. Therefore, we assessed whether a 1-day cadaver-based seminar is effective for trauma surgery training. Methods: Data were collected from 11 seminars carried out from January 2013 to March 2014, including a 10-point self-assessment of confidence levels (SACL) for 21 surgical skills and an evaluation of the contents before, just after, and a half-year after the seminar. Statistical analysis was undertaken using the paired t-test at P < 0.0167. Results: A total of 135 participants were divided into three groups based on experience and clinical careers. The SACL improved in all skills between before and just after the seminar, however, they decreased between just after and a half-year after the seminar. The SACL did not change significantly in all skills between just after and a half-year after the seminar in highly experienced and experienced group members belonging to an emergency center. Conclusions: A cadaver-based seminar provided more self-confidence just after the seminar for participants at all experience levels. This effect was not maintained after a half-year, except in participants who can practice the skills at an emergency center. Practicing and participating in the seminar repeatedly is suggested to be effective for skills retention in trauma surgery.

Low-dose immunoglobulin G is not associated with mortality in patients with sepsis and septic shock.

BACKGROUND: The administration of low-dose intravenous immunoglobulin G (IVIgG) (5 g/day for 3 days; approximate total 0.3 g/kg) is widely used as an adjunctive treatment for patients with sepsis in Japan, but its efficacy in the reduction of mortality has not been evaluated. We investigated whether the administration of low-dose IVIgG is associated with clinically important outcomes including intensive care unit (ICU) and in-hospital mortality. METHODS: This is a post-hoc subgroup analysis of data from a retrospective cohort study, the Japan Septic Disseminated Intravascular Coagulation (JSEPTIC DIC) study. The JSEPTIC DIC study was conducted in 42 ICUs in 40 institutions throughout Japan, and it investigated associations between sepsis-related coagulopathy, anticoagulation therapies, and clinical outcomes of 3195 adult patients with sepsis and septic shock admitted to ICUs from January 2011 through December 2013. To investigate associations between low-dose IVIgG administration and mortalities, propensity score-based matching analysis was used. RESULTS: IVIgG was administered to 960 patients (30.8%). Patients who received IVIgG were more severely ill than those who did not (Acute Physiology and Chronic Health Evaluation (APACHE) II score 24.2 ± 8.8 vs 22.6 ± 8.7, p < 0.001). They had higher ICU mortality (22.8% vs 17.4%, p < 0.001), but similar in-hospital mortality (34.4% vs 31.0%, p = 0.066). In propensity score-matched analysis, 653 pairs were created. Both ICU mortality and in-hospital mortality were similar between the two groups (21.0% vs 18.1%, p = 0.185, and 32.9% vs 28.6%, p = 0.093, respectively) using generalized estimating equations fitted with logistic regression models adjusted for other therapeutic interventions. The administration of IVIgG was not associated with ICU or in-hospital mortality (odds ratio (OR) 0.883; 95% confidence interval (CI) 0.655-1.192, p = 0.417, and OR 0.957, 95% CI, 0.724-1.265, p = 0.758, respectively). CONCLUSIONS: In this analysis of a large cohort of patients with sepsis and septic shock, the administration of low-dose IVIgG as an adjunctive therapy was not associated with a decrease in ICU or in-hospital mortality.

Antithrombin Supplementation and Mortality in Sepsis-Induced Disseminated Intravascular Coagulation: A Multicenter Retrospective Observational Study.

Supplemental doses of antithrombin (AT) are widely used to treat sepsis-induced disseminated intravascular coagulation (DIC) in Japan. However, evidence on the benefits of AT supplementation for DIC is insufficient. This multicenter retrospective observational study aimed to clarify the effect of AT supplementation on sepsis-induced DIC using propensity score analyses. Data from 3,195 consecutive adult patients admitted to 42 intensive care units for severe sepsis treatment were retrospectively analyzed; 1,784 patients were diagnosed with DIC (n = 715, AT group; n = 1,069, control group). Inverse probability of treatment-weighted propensity score analysis indicated a statistically significant association between AT supplementation and lower in-hospital all-cause mortality (n = 1,784, odds ratio [95% confidence intervals]: 0.748 [0.572-0.978], P = 0.034). However, quintile-stratified propensity score analysis (n = 1,784, odds ratio: 0.823 [0.646-1.050], P = 0.117) and propensity score matching analysis (461 matching pairs, odds ratio: 0.855 [0.649-1.125], P = 0.263) did not show this association. In the early days after intensive care unit admission, the survival rate was statistically higher in the propensity score-matched AT group than in the propensity score-matched control group (P = 0.007). In DIC patients without concomitant heparin administration, similar results were observed. In conclusion, AT supplementation may be associated with reduced in-hospital all-cause mortality in patients with sepsis-induced DIC. However, the statistical robustness of this connection was not strong. In addition, although the number of transfusions needed in patients with AT supplementation increased, severe bleeding complications did not.

Characteristics, treatments, and outcomes of severe sepsis of 3195 ICU-treated adult patients throughout Japan during 2011-2013.

Severe sepsis is a major concern in the intensive care unit (ICU), although there is very little epidemiological information regarding severe sepsis in Japan. This study evaluated 3195 patients with severe sepsis in 42 ICUs throughout Japan. The patients with severe sepsis had a mean age of 70 ± 15 years and a mean Acute Physiology and Chronic Health Evaluation II score of 23 ± 9. The estimated survival rates at 28 and 90 days after ICU admission were 73.6 and 56.3 %, respectively.

[A Case of Squamous Cell Carcinoma of the Right Breast].

Squamous cell carcinoma(SCC)of the breast is rare and its clinicopathological features have not been fully elucidated. We report a patient with SCC of the right breast who underwent surgical resection. A 51-year-old woman was admitted to our hospital because of a right breast tumor. A round tumor with an irregular surface measuring about 3.0×2.5 cm was palpable in the ACarea of the right breast. No abnormal data were observed on laboratory examination, including tumor markers such as carcinoembryonic antigen(CEA), cancer antigen 15-3(CA15-3), breast cancer antigen 225(BCA225), and SCC antigen. Mammography showed a mass with spiculation measuring 2.7×1.7 cm. Ultrasonography also demonstrated a hypoechoic solid tumor with an irregular surface, measuring 2.6×1.6 cm. The pathological diagnosis of a needle biopsy specimen was a mixed type of SCC. We performed a typical right mastectomy with axillary and supraclavicular lymph node dissection. The tumor size was 2.8×1.8 cm. SCC was histologically diagnosed. There was partial invasion to other tissues. The dissected lymph nodes were not involved by carcinoma. Hormone receptors(estrogen and progesterone)and HER2 results were negative. The pathological Stage was II A(T2, N0, M0). The patient refused chemotherapy. However, her condition remains satisfactory without recurrence 2 years after surgery.

[Usefulness of Transnasal Decompression Tubes in Patients with Right-Sided Obstructive Colorectal Cancer].

PURPOSE: We performed this retrospective study to evaluate the usefulness of a transnasal decompression tube(long ileus tube)as a bridge to surgery in patients with right-sided obstructive colorectal cancer. PATIENTS AND METHODS: There were 8 patients(5 men and 3 women, aged 64 to 85 years with a mean age of 75.9 years)who had undergone transnasal decom- pression in the last 10 years. RESULT: 1) The success rate of intubation was 100%(8/8). 2) Primary cancer location: Ascend- ing colon cancers were 37.5%(3/8)and right-sided transverse colon cancers 62.5%(5/8). 3) Decompression periods were from 1 to 43 days, with a mean period of 12.8 days. 4) Stage: Stage II was found at 12.5%(1/8), Stage II , III a, III b and IV were found at 25.0%(2/8), respectively. Advance Stages( III a, III b, and IV )were 75.0%(6/8). 5) Pathology: Well differentiated tubular adenocarcinoma(tub1)was at 37.5%(3/8)and moderately differentiated tubular adenocarcinoma (tub2)at 62.5%(5/8). 6) Operative procedures: Radical operation was performed in 6 cases except for 2 cases with stage IV disease. 7) Complications: Early complication were found in 37.5% of the cases(3/8). Wound infection was found in 12.5%(1/8), wound infection with rupture in 12.5%(1/8), and adhesive ileus in 12.5%(1/8). 8) Outcomes: The 5-year survival was 37.5%(3/8). CONCLUSION: Transnasal tube decompression for right-sided malignant colorectal obstruction is useful for avoiding an emergency operation, and a single-stage operation can be performed in patients excluding Stage IV disease.

Practice Guidelines for Primary Care of Acute Abdomen 2015.

Since acute abdomen requires accurate diagnosis and treatment within a particular time limit to prevent mortality, the Japanese Society for Abdominal Emergency Medicine, in collaboration with four other medical societies, launched the Practice Guidelines for Primary Care of Acute Abdomen that were the first English guidelines in the world for the management of acute abdomen. Here we provide the highlights of these guidelines (all clinical questions and recommendations were shown in supplementary information). A systematic and comprehensive evaluation of the evidence for epidemiology, diagnosis, differential diagnosis, and primary treatment for acute abdomen was performed to develop the Practice Guidelines for Primary Care of Acute Abdomen 2015. Because many types of pathophysiological events underlie acute abdomen, these guidelines cover the primary care of adult patients with nontraumatic acute abdomen. A total of 108 questions based on nine subject areas were used to compile 113 recommendations. The subject areas included definition, epidemiology, history taking, physical examination, laboratory test, imaging studies, differential diagnosis, initial treatment, and education. Japanese medical circumstances were considered for grading the recommendations to assure useful information. The two-step methods for the initial management of acute abdomen were proposed. Early use of transfusion and analgesia, particularly intravenous acetaminophen, were recommended. The Practice Guidelines for Primary Care of Acute Abdomen 2015 have been prepared as the first evidence-based guidelines for the management of acute abdomen. We hope that these guidelines contribute to clinical practice and improve the primary care and prognosis of patients with acute abdomen.

The Practice Guidelines for Primary Care of Acute Abdomen 2015.

BACKGROUND: Since acute abdomen requires accurate diagnosis and treatment within a particular time limit to prevent mortality, the Japanese Society for Abdominal Emergency Medicine in collaboration with four other medical societies launched the Practice Guidelines for Primary Care of Acute Abdomen that were the first English guidelines in the world for the management of acute abdomen. Here we provide the highlights of these guidelines [all clinical questions (CQs) and recommendations are shown in supplementary information]. METHODS: A systematic and comprehensive evaluation of the evidence for epidemiology, diagnosis, differential diagnosis, and primary treatment for acute abdomen was performed to develop the Practice Guidelines for Primary Care of Acute Abdomen 2015. Because many types of pathophysiological events underlie acute abdomen, these guidelines cover the primary care of adult patients with nontraumatic acute abdomen. RESULTS: A total of 108 questions based on 9 subject areas were used to compile 113 recommendations. The subject areas included definition, epidemiology, history taking, physical examination, laboratory test, imaging studies, differential diagnosis, initial treatment, and education. Japanese medical circumstances were considered for grading the recommendations to assure useful information. The two-step methods for the initial management of acute abdomen were proposed. Early use of transfusion and analgesia, particularly intravenous acetaminophen, were recommended. CONCLUSIONS: The Practice Guidelines for Primary Care of Acute Abdomen 2015 have been prepared as the first evidence-based guidelines for the management of acute abdomen. We hope that these guidelines contribute to clinical practice and improve the primary care and prognosis of patients with acute abdomen.

Relationships between pre-hospital characteristics and outcome in victims of foreign body airway obstruction during meals.

OBJECTIVE: The purpose of this study is to determine the outcome of foreign body airway obstruction according to the initial actions taken for choking victims during meals. METHODS: Our subjects were patients who became unresponsive or unconscious because of foreign body airway obstruction (FBAO) during meals in the presence of bystander witnesses. We investigated the associations between outcome and the following factors: age, gender, type of foreign body, chest compressions after the patient became unresponsive or unconscious, episode of cardiac arrest, efforts by a bystander to remove the foreign body, eating-related activities of daily living, time elapsed from the 119 call to arrival of emergency medical technicians (EMTs), and time elapsed from the 119 call to hospital arrival (primary endpoint). RESULTS: Of the 138 patients enrolled during the study period, 35 (25.4%) received chest compressions by bystanders after becoming unresponsive or unconscious and 69 (50.0%) suffered cardiac pulmonary arrest. Chest compressions by a bystander after the victim became unresponsive or unconscious (p<0.0001) and no CPA (p<0.0001) were significantly related to good outcome. Chest compressions by a bystander were both associated with good neurological outcome (odds ratio, 10.57; 95% CI, 2.472-65.059, p<0.0001). No CPA after FBAO was another independent predictor (odds ratio, 50.512; 95% CI, 13.45-284.41; p<0.0001), but efforts to remove the foreign body before the arrival of EMTs did not affect outcome. CONCLUSION: Chest compressions by a bystander, a support received by only 25% of the patients, proved to be essential for improved outcome for choking victims who became unresponsive or unconscious. Education for lay-rescuer response to choking might further improve overall outcome.
