Successful multi-stage treatment of stoma limb perforation following Hartmann's operation report a case.

BACKGROUND: Stoma-related complications are not rare, whereas the spontaneous perforation of the stoma limb is relatively rare. Herein, we report a case of stoma limb perforation which occurred after Hartmann's operation. CASE PRESENTATION: A 50-year-old Japanese man presented to our Hospital with acute and severe abdominal pain. Abdominal computed tomography (CT) scan revealed that an abscess with free air was formed around the sigmoid colon. We performed Hartmann's operation, whereas he experienced redness, purulent discharge, and swelling around the colostomy at 10 days postoperatively. The contrast-enhanced CT scan of the abdomen revealed an abscess formation with air around the colostomy. He was diagnosed with an abdominal wall abscess due to perforation of the stoma limb. After the drainage, his symptoms were ameliorated by oral analgesics, anti-inflammatory drugs, and prophylactic antibiotic. Four months after the first operation, we performed a closedown of the sigmoid colostomy and fistula resection. The patient's postoperative course was uneventful, and he was discharged 14 days later. CONCLUSIONS: This case depicts rare complications of Hartmann's operation. Operation is usually performed in patients with stoma limb perforation. However, if they are stable and the abscess is located in their abdominal wall, they may be treated successfully using a multi-stage approach of local drainage toward the stoma wall followed by stoma closure.

Endoscopic sphincterotomy to prevent post-ERCP pancreatitis in patients with biliary neoplasms: a multicenter retrospective cohort study.

Background and aims Treatment of biliary neoplasms often involves multiple endoscopic retrograde cholangiopancreatography (ERCP)-related procedures. Endoscopic sphincterotomy (ES) may prevent post-ERCP pancreatitis (PEP). This retrospective, multicenter cohort study aimed to investigate the effectiveness of ES for prevention of PEP in patients with biliary neoplasm. Methods Patients with biliary duct neoplasm who underwent ERCP between January 2006 and December 2016 were enrolled. The frequency of PEP was compared between the ES and non-ES groups using propensity score analysis. The effectiveness of ES in subgroups of patients who underwent biliary duct stent placement, intraductal ultrasound (IDUS), and transpapillary biliary duct biopsy was analyzed by logistic regression. Results Of the 362 patients enrolled, 84 (23.2 %) developed PEP. Propensity score matching for PEP risk factors in 172 ERCP procedures showed that the frequency of PEP in the ES group was lower than that in the non-ES group (19.7 % vs. 33.7 %). Non-ES was also an independent risk factor for PEP in patients who underwent intraductal ultrasound and transpapillary biliary duct biopsy (RR = 4.54 and 5.26), but was not an independent risk factor for PEP in patients with biliary duct stents. In addition, there was no evidence that the frequency of PEP was statistically different between patients with plastic stents and metal stents in the ES and non-ES groups ( P  = 0.14 and 0.10). Conclusions ES is an effective technique to prevent PEP in patients with biliary neoplasms. In particular, ES is a safe technique to prevent PEP when performing IDUS and transpapillary biliary duct biopsy.

Prospective comparison study of franseen needle and standard needle use for pancreatic lesions under EUS guidance.

BACKGROUND AND OBJECTIVES: A needle with Franseen geometry for fine needle aspiration is now available. However, no reports have described prospective evaluations of the Franseen needle or comparisons with the standard needle. The aim of this comparative prospective study was to evaluate the histological diagnostic yield of the Franseen needle and the standard needle using tissue obtained by a single pass of each for the same lesion. PATIENTS AND METHODS: In this study, only tissue obtained by the first pass using the Franseen needle was used. As a comparison group, only tissue obtained from the same lesion by a second pass using the standard needle was used. Evaluation of the histological diagnostic yield of the needles was based on tissue obtained by each single pass with no additional passes. RESULTS: A total of 56 patients were prospectively enrolled. The rate of adequate tissue obtained was significantly higher for the Franseen needle than for the standard needle (89.4% vs. 62.5%, respectively; P < 0.05). The sensitivity and accuracy of the Franseen needle were 80.7%, and 84.6%, respectively, while those for the standard needle were 59.6% and 63.5%, respectively. CONCLUSIONS: The Franseen needle offers a better rate of obtaining adequate tissue and higher diagnostic accuracy than the standard needle.

Technical feasibility of EUS-guided antegrade dilation for hepaticojejunostomy anastomotic stricture using novel endoscopic device (with videos).

Background: A novel endoscopic dilation device (EZ Dilator; Zeon Medical Co, Tokyo, Japan) is now available in Japan that might affect dilation for biliary strictures under endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic ultrasound (EUS) guidance because it has good push ability. We evaluated the technical feasibility of this device under EUS guidance in a case series of patients with hepaticojejunostomy anastomotic stricture (HJAS) that led to further complications. Method: We enrolled 14 patients with HJAS leading to obstructive jaundice or repeated cholangitis in this study. Technical success was defined as insertion of the EZ Dilator into the intestine across the stricture site without the need for other dilation devices. Deployed plastic stents were removed after three months to evaluate anastomosis sites. Results: The median procedural duration was 25 minutes. Rates of technical and clinical success were 100% and 78.5%, respectively. One patient developed an adverse event of abdominal pain. Contrast medium flowed across the anastomosis site in 11 patients after stent removal, indicating a clinical success rate of 78.5% (11 of 14). Plastic stents were deployed again in the remaining three patients. Conclusion: Although a prospective evaluation with long-term follow up is needed, the EZ Dilator shows clinical promise for treating benign biliary strictures under ERCP and EUS guidance.

Electrohydraulic Lithotripsy for Pancreatic Duct Stones Under Digital Single-Operator Pancreatoscopy (with Video).

BACKGROUND: Recently, a digital single-operator cholangiopancreatoscope (DSOC) has become available. This system allows the performance of electrohydraulic lithotripsy (EHL) even within the main pancreatic duct (MPD). However, there are only few reports of EHL for MPD stones using SPY-DS. AIMS: The aim of this study was to evaluate the technical feasibility and efficacy of EHL for MPD stones under DSOC guidance. METHODS: Between October 2016 and August 2017, patients with MPD stones were retrospectively enrolled in this study. The presence of MPD stones was diagnosed by endoscopic ultrasound and MRCP. The patients' baseline characteristics and those of the stones, including their size, number, and site in the MPD, number of EHL procedures, and adverse events, were reviewed. RESULTS: A total of 21 patients were retrospectively enrolled. The etiologies of chronic pancreatitis were idiopathic (n = 4) and alcohol induced (n = 17). The pancreatic stone was variously located in the head (n = 6), body (n = 11), tail (n = 1), head and body (n = 2), and body and tail (n = 1) of the pancreas. Median pancreatic stone size was 12 mm, and the mean number of ERCP sessions was 1.29 (range 1-3). EHL was successfully performed in 15 patients (85.7%, 18/21), and the rate of complete stone clearance was 88.2% (18/21). Severe adverse events were not seen in any of the patients, although one patient developed mild acute pancreatitis. CONCLUSIONS: In conclusion, although additional case reports and prospective studies are needed, EHL under DSOC may be an option to treat MPD stones.

EUS-guided versus percutaneous biliary access in patients with obstructive jaundice due to gastric cancer.

BACKGROUND: Gastric cancer is sometimes complicated by obstructive jaundice. However, ERCP may be challenging in patients who have advanced gastric cancer, or recurrent gastric cancer after surgical resection that is complicated by obstructive jaundice. In such cases, percutaneous transhepatic biliary drainage (PTBD) is considered. Recently, EUS-guided biliary drainage (EUS-BD) has been developed. We conducted a retrospective study to compare the efficacy of EUS-BD and PTBD in patients with obstructive jaundice due to gastric cancer. METHODS: Patients with gastric cancer complicated with obstructive jaundice who were contraindicated for standard ERCP were enrolled. RESULTS: A total of 47 consecutive patients were enrolled during the study period. The technical success rates of PTBD and EUS-BD were 88.9% (16/18) and 96.7% (29/30), respectively (P = 0.64). The stent patency period, including patient death was equivalent between the two groups (EUS-BD vs. PTBD: 188.4 days vs. 200.9 days, P = 0.974). Time to stent dysfunction in the EUS-BD group (391.1 days) was not significantly different as compared to that in the PTBD group (398.1 days) (P = 0.78). Adverse events were relatively severe in the PTBD group. CONCLUSIONS: Given the relative severity of adverse events in the PTBD group, EUS-BD might be the procedure of choice for gastric cancer patients with contraindications by inability to perform ERCP.

Pilot Study of Dumbbell-Type Covered Self-Expandable Metal Stent Deployment for Benign Pancreatic Duct Stricture (with Videos).

BACKGROUND: Fully-covered, self-expandable metal stents (FCSEMS) have been deployed to treat symptomatic chronic pancreatitis (CP) complicated with main pancreatic duct (MPD) stricture. Although this strategy can be effective, it has the disadvantages of stent migration or stent-induced ductal change. Removal of an FCSEMS can also be challenging in the face of distal migration because of MPD stricture. Dumbbell-type FCSEMS have been developed to prevent stent-induced ductal changes and improve removability when treating benign biliary stricture. This stent might also confer clinical benefits upon patients with MPD stricture. AIMS: The present pilot study aimed to determine the feasibility and safety of deploying dumbbell-type FCSEMS in patients with CP complicated by MPD stricture. METHOD: Stents were deployed in 22 patients with MPD stricture caused by CP and complicated by abdominal pain. RESULTS: Strictures were located at the head (n = 19), body (n = 2), and head and tail (n = 1) of the MPD. Stents were deployed above the papilla in three patients. All stents were deployed for a median duration of 142 (range, 49-190) days and removed. The resolution of MPD strictures was confirmed by pancreatography in 19 (86.3%) patients. Two metal stents that spontaneously tore during removal from two patients had otherwise functioned normally. Only three patients developed recurrent MPD stricture during a median follow-up of 419 (range, 261-484) days.. CONCLUSIONS: Deployment of a dumbbell-type FCSEMS seems feasible for MPD stricture, and the rate of adverse events is acceptable.

Clinical Impact of Recombinant Soluble Thrombomodulin for Disseminated Intravascular Coagulation Associated with Severe Acute Cholangitis.

Background/Aims: Recently, recombinant human soluble thrombomodulin (rTM) has been developed as a new drug for disseminated intravascular coagulation (DIC). This study aims to evaluate the clinical benefit of rTM in patients with sepsis-induced DIC caused by acute cholangitis who underwent biliary drainage. Methods: Patients were divided into two groups: the rTM therapy group and the non-rTM therapy group. The primary outcome was the DIC resolution rate at 7 days, and the secondary outcome was 28-day mortality rate. Results: Thirty-five patients were treated by rTM, and 36 patients were treated without rTM for DIC. The rate of resolution of DIC at day 7 was significantly higher in the rTM group than in the non-rTM group (82.9% vs 55.6%, p=0.0012). Compared with the non-rTM group, the 28-day survival rate of the r-TM group was significantly higher (rTM vs non-rTM, 91.4% vs 69.4%, p=0.014). According to multivariate analysis, non-rTM (hazard ratio [HR], 2.681) and CRP (HR, 2.370) were factors related to decreased survival. Conclusions: rTM treatment may have a positive impact on improving DIC and survival rates in patients with severe acute cholangitis.

Prospective histological evaluation of a 20G core trap with a forward-cutting bevel needle for EUS-FNA of pancreatic lesions.

BACKGROUND: Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) has been established as a method to obtain tissues of various organs. To obtain sufficient tissue has clinical impact to facilitate the diagnosis by clinical pathologists, the assessment and subtyping of various neoplasms, and for further immunohistochemical investigations of tumor type. Recently, a novel 20G core trap with a forward-cutting beveled FNA needle (ProC-F) has become available. The aim of this prospective study was to evaluate the feasibility and diagnostic yield of EUS-FNA for pancreatic lesions using this needle. PATIENTS AND METHOD: In this study, the first puncture was performed using the ProC-F. Only tissue obtained with the first puncture using the ProC-F was used to evaluate diagnostic yield of ProC-F. The second puncture was performed using a 22G standard FNA needle using the same technique as for the first puncture. Second puncture was performed if the endosonographer did not feel that sufficient tissue had not been obtained by first puncture. RESULTS: Fifty-three consecutive patients who underwent EUS-FNA for pancreatic lesions were prospectively enrolled. The technical success rate of EUS-FNA using the ProC-F was 98.1% (52/53). The rate of adequate tissue obtained by ProC-F was 96.2% (50/52). On the other hand, the rate of adequate tissue obtained by the standard needle was 71.1%. The sensitivity, specificity, negative predictive value (NPV), positive predictive value (PPV), and accuracy of the ProC-F and the standard needle were 92.5, 100, 100, 76.9, and 94.0%, and 85.2, 100, 100, 55.6, and 87.5%, respectively. Diagnostic yield of ProC-F about sensitivity (P = 0.027), NPV (P = 0.035), and accuracy (P = 0.004) was significantly higher than of standard needle. Adverse events were not seen in any patients. CONCLUSIONS: Although only tissue obtained by the first puncture was evaluated, the rate of adequate tissue and the histologic diagnostic yield for pancreatic lesions were extremely high using the ProC-F.

Electrohydraulic Lithotripsy for Difficult Bile Duct Stones under Endoscopic Retrograde Cholangiopancreatography and Peroral Transluminal Cholangioscopy Guidance.

Background/Aims: Electrohydraulic lithotripsy (EHL) under endoscopic retrograde cholangiopancreatography (ERCP) guidance can be an option to treat difficult stones. Recently, a digital, single-operator cholangioscope (SPY-DS) has become available. Peroral transluminal cholangioscopy (PTLC) using SPY-DS has also been reported. In this retrospective study, the technical feasibility and clinical effectiveness of EHL for difficult bile duct stones under ERCP guidance and under PTLC guidance was examined. Methods: In this pilot study, patients with difficult bile duct stones between July 2016 and July 2017 were retrospectively enrolled. Results: Forty-two consecutive patients underwent EHL using a SPY-DS; 34 patients underwent EHL under ERCP guidance, and the other 8 patients underwent EHL under PTLC guidance. Median procedure time was 31 minutes (range, 19 to 66 minutes). The median number of EHL sessions was 1 (range, 1 to 2), and that of ERCP sessions was also 1 (range, 1 to 3). The rate of complete stone clearance was 98% (41/42). Adverse events such as cholangitis and acute pancreatitis were seen in 14% (6/42), which could be treated conservatively. Conclusions: EHL using SPY-DS was technically feasible, not only under ERCP guidance, but also PTLC guidance. A prospective clinical study of EHL using SPY-DS is needed.

Correlation of lanthanum dosage with lanthanum deposition in the gastroduodenal mucosa of dialysis patients.

Lanthanum (La) deposition has been observed in gastrointestinal mucosa of dialysis patients treated with La carbonate to treat hyperphosphatemia in the 6 years since its authorization in Japan. We investigated gastrointestinal biopsies from 112 dialysis patients, and found 15 cases of histiocytic aggregation with crystalloids and one case of duodenitis with histiocyte aggregation without crystalloids in the 30 patients treated with La carbonate. No histiocytic lesions were observed in the 82 patients without La carbonate administration. So far in total 70 cases of La deposition in the alimentary tract have been reported, including our 16 cases. Neither clinical nor histological findings other than histiocytic aggregation were specific in the patients with La deposition. We also compared the groups with and without La deposition, revealing that the daily and total doses of La carbonate showed statistically significant correlations with La deposition. However the causality with their histologic features, e.g. intestinal metaplasia and degree of inflammation, were inconclusive between the two groups. Although no critical symptoms have been reported, it is necessary to accumulate more cases to clarify the mechanism of La deposition, because dialysis patients must take phosphate buffers for a long period.

A feasibility study of digital single-operator cholangioscopy for diagnostic and therapeutic procedure (with videos).

Recently, the novel SpyGlass DS Direct Visualization system (SPY DS) has become available. This system offers several advantages over the conventional SPYGlass system. This study evaluated the clinical feasibility and efficacy of diagnostic and therapeutic procedures for biliary disorder using SPY DS.In this retrospective study, consecutive patients who had biliary disorder were enrolled between November 2015 and February 2016. All patients could not be diagnosed or treated by standard endoscopic retrograde cholangiopancreatography in our hospital or at another hospital.A total of 28 consecutive patients (21 men and 7 women; median age, 73 years; age range, 55-87 years) were retrospectively enrolled in this study. Among them, diagnostic procedure was performed in 20 patients, and 8 patients underwent therapeutic procedures. The technical success rate for diagnostic procedures was 100% (20/20). Diagnostic accuracy was 100% (19/19). The technical success rate for therapeutic procedures was 88% (7/8). Among these 8 patients, 4 patients with common bile duct stones underwent electrohydraulic lithotripsy. One patient successfully underwent guidewire insertion to remove a migrated plastic stent. The 3 remaining patients underwent SPY DS to insert a guidewire for left bile duct obstruction and for posterior bile duct branch. In the patient who underwent guidewire insertion for left hepatic bile duct obstruction cause by primary sclerosing cholangitis, we could not advance the guidewire into the left hepatic bile duct. No adverse events were seen. Median SPY DS insertion time was 21 min (range, 8-32 min).Single-operator cholangioscopy using SPY DS was feasible and had a marked clinical impact in patients with biliary disease. Additional case reports and prospective studies are needed to examine further applications of this system.

Prospective evaluation of digital single-operator cholangioscope for diagnostic and therapeutic procedures (with videos).

BACKGROUND AND AIM: Recently, the digital single-operator cholangioscope (SPY-DS) has become available. This system may allow diagnosis by direct visualization and allow performance of various therapeutic procedures. The aim of the present study was to prospectively evaluate the clinical utility of DSOCS for diagnostic and therapeutic procedures for biliary disease. METHODS: Technical success was defined as successful visualization of target lesions in the biliary tract and carrying out forceps biopsy as a diagnostic procedure, and successfully carrying out treatment such as guidewire insertion for the area of interest, electrohydraulic lithotripsy (EHL), or migrated stent removal. Also, the present study aimed at investigating diagnostic yield of the cholangioscopic findings and biopsy specimens. RESULTS: A total of 55 consecutive patients were prospectively enrolled in this study; a diagnostic procedure was done in 33 patients, and a therapeutic procedure was done in 22 patients. Overall accuracy of visual findings was 93%, with a sensitivity of 83%, a specificity of 89%, positive predictive value (PPV) of 83%, and negative predictive value (NPV) of 100%. However, the overall accuracy of forceps biopsy was 89%, with a sensitivity, specificity, and PPV of 100%, and NPV of 90%. Overall technical success rate of therapeutic procedures such as selective guidewire insertion, EHL or migrated stent removal was 91% (20/22). Finally, adverse events were seen in two cases in the diagnostic group, but were not seen in the therapeutic group. CONCLUSION: Although additional cases and a randomized, controlled study with another cholangioscope are needed, diagnostic and therapeutic procedures using SPY-DS appear to be feasible and safe.

Impact of continuous in-home rehabilitation on quality of life and activities of daily living in elderly clients over 1 year.

AIM: To verify the effect of in-home rehabilitation on quality of life and activities of daily living in elderly clients. METHODS: In this non-randomized controlled intervention trial, elderly participants were separated into a rehabilitation or a non-rehabilitation group (n = 100 each). The non-rehabilitation group received basic in-home nursing care, including assistance with cooking, cleaning, toileting, meals and medication. The rehabilitation group received a physical treatment program provided by a licensed professional once a week and basic nursing care in the home. For each group, quality of life and activities of daily living were assessed approximately every 3 months over a 1-year period. Quality of life was evaluated using the Philadelphia Geriatric Center Morale Scale, and activities of daily living were evaluated based on the Functional Independence Measure. RESULTS: The rehabilitation group showed statistically significant improvements in both quality of life and activities of daily living. In contrast, the non-rehabilitation group, although showing slight improvement in quality of life at 9 months, showed almost no effects at the other time-points and no significant changes in activities of daily living over the course of the study. CONCLUSIONS: The results of the present study suggest that long-term continuous in-home rehabilitation might improve quality of life and activities of daily living in elderly clients.

Evaluation of the safety of endoscopic radiofrequency ablation for malignant biliary stricture using a digital peroral cholangioscope (with videos).

BACKGROUND AND AIM: The clinical impact of catheter-based radiofrequency ablation (RFA) under endoscopic retrograde cholangiopancreatography (ERCP) guidance has recently been reported; however, severe adverse events have also been noted. If tumor is not present in the biliary tract, severe adverse events such as perforation or bleeding as a result of vessel injury around the biliary tract may occur. In addition, the effectiveness of RFA may not be sufficient based solely on radiographic guidance. The aim of the present study was to evaluate the actual feasibility of intraductal RFA by peroral cholangioscope (POCS) evaluation before/after RFA. METHODS: In this retrospective study carried out between July and September 2016, consecutive patients who underwent RFA for malignant biliary stricture and POCS evaluation before/after RFA were enrolled. Primary endpoint of this study was technical feasibility of RFA, which was evaluated by POCS. Secondary endpoints were rates and types of adverse event. RESULTS: A total of 12 consecutive patients were retrospectively enrolled in this study. Stent placement using uncovered metal stents had been previously done in six patients before RFA. Tumor was seen in the biliary tract in all patients. RFA was technically successful in all patients, and clinical success was confirmed in all patients by POCS imaging. Adverse events were seen in only one patient. Median stent patency was 154 days. CONCLUSIONS: RFA for malignant biliary stricture may be safe. To confirm the feasibility and efficacy of RFA, additional cases, prospective studies, and a comparison study between with and without endobiliary RFA are needed.

Quality of life in elderly people at the start of using in-home care.

BACKGROUND: Quality of life (QOL) among 200 elderly people planning to use in-home care services available to those with severe illness was surveyed to identify the most effective method of improving QOL of the elderly through such care services. RESULTS: QOL was surveyed using a PGC Morale Scale, and factors related to QOL were verified by multivariate analysis. The most relevant factors for QOL among the 11 analyzed were the client's reason for choosing to use in-home care services and the client's family structure. The average PGC-MS score was 9.09 ± 2.6 (mean ± standard deviation). Analysis of factors significantly affecting PGC-MS score identified treatment history and job type (p < 0.001), family structure (p < 0.009), age (p < 0.008), and years of education (p < 0.029). In addition, after performing multiple regression analysis using treatment history, years of education, employment history, and family structure as independent variables, treatment history (visiting a hospital and receiving treatment but deciding to use in-home care services later) remained significantly related to PGC-MS score (p < 0.001), as did family structure (three-generation families; p < 0.001). Further, with regard to treatment history, PGC-MC scores were higher in those who visited a hospital and received treatment but decided to use in-home care services later than in those who decided to enroll in the care service while still in the hospital. In contrast, with regard to family structure, PGC-MS scores decreased in the order of three-generation families, those living alone, couples, and two-generation families. CONCLUSIONS: QOL of elderly people might be improved by the provision of in-home care services with consideration of consumers' intentions and factors known to influence QOL.

In-home occupational therapy for a patient with stage IV lung cancer: changes in quality of life and analysis of causes.

INTRODUCTION: We tracked and analyzed the changes in the quality of life (QOL) of a stage 4 lung cancer patient receiving occupational therapy at home. CASE DESCRIPTION: In a longitudinal study consisting of 4 evaluations over 9 months, a 66-year-old female with lung cancer was assessed using the Philadelphia Geriatric Center (PGC) Morale Scale and the 100-Point Satisfaction Scale. The QOL scores over time and factors influencing changes in these scores were analyzed. DISCUSSION AND EVALUATION: A histogram of QOL scores demonstrated a rapid increase followed by a mild decrease and then stable level. Interviews revealed the patient's response to knowing her life expectancy, meeting a qualified occupational therapist, increasing her leisure activity, changing her family relationships and facing the prospect of death. We also confirmed that occupational therapy, such as writing letters or keeping a diary, reminded her of her late parents, hometown and childhood and helped her accept death. CONCLUSIONS: For a terminal lung cancer patient, meeting an occupational therapist to discuss fear or self-loathing improved QOL. Further, an active lifestyle played an important role in helping the patient accept death and lead a peaceful and stable life.
