We evaluated the effect of jidabokuippo for postoperative finger swelling with a ring gauge. We recruited 112 patients who took jidabokuippo and 134 patients who did not take jidabokuippo after surgery of the upper extremities. Postoperative finger swelling was evaluated using a ring gauge. The size difference between affected and unaffected fingers was measured. The mean time to remission of swelling after surgery for traumatic/non-traumatic disorders was 4.3/2.2 weeks in the jidabokuippo group and 7.2/3.4 weeks in the nonjidabokuippo group. Time was significantly shorter in the jidabokuippo group. The size difference between affected and unaffected fingers at 1, 2, 4, 8, 12 weeks after traumatic/non-traumatic surgery was 0.9, 0.4, 0.3, 0.1, 0.1/0.4, 0.3, 0.3, 0.2, and 0.1 respectively in the jidabokuippo group and 3.3, 3.0, 2.1, 1.2, 0.8/1.2, 0.8, 0.4, 0.2, and 0.2 in the non-jidabokuippo group. The jidabokuippo group had significantly more robust remission effect in finger swelling (P < 0.01)

We report a successful case of graft replacement for ascending and aortic arch aneurysm which developed 5 years after CABG. A 75-year-old woman, who underwent emergency CABG (LITA-LAD, SVG-RCA) 5 years previously, was admitted to our hospital due to an abnormal shadow on chest roentogenogram. Aortogram and coronary angiogram revealed ascending and aortic arch aneurysm and patent LITA and SVG. Graft replacement of the ascending and total aortic arch was carried out using four branched grafts (Gelweave 26/10/8/8*8). Cardiopulmonary bypass was established with right axillary arterial perfusion and bicaval cannulation. Cardiac arrest was obtained with cold blood cardioplegia using both retrograde and antegrade techniques. Selective cerebral perfusion was used for brain protection. The patient was discharged without any complication on the 27th postoperative day.

The removal of aspiration objects is often required for aspiration, which takes place at the time of a video fluoroscopic examination of swallowing (VF) for the assessment of dysphagia rehabilitation. We report our approach against correspondence for aspiration at VF. As subjects for this report, we sampled 6 patients (average age: 78.3±3.0, four males and two females) from 19 patients, who had aspiration of barium sulfate or meal with barium contrast medium at the time of VF form October 1, 2009, to March 31, 2011. For the first step of correspondence for aspiration at VF, we dealt with coughing, huffing, suction and postural drainage under the guidance of a Speech-Language-Hearing Therapist and, depending on the case, a Physical Therapist who dealt with chest physical therapy. When expectoration was found impossible, we checked to see if it was necessary to perform biphasic cuirass ventilation with a clinical engineer. We assessed the chest X-ray films and existence or non-existence of expectoration immediately after aspiration, and fever, inflammatory response, respiratory symptoms and gastrointestinal symptoms one week after the examination, and retrospectively checked the influence of aspiration. As a result, three patients had residue as revealed on chest X-ray films, and the three remaining patients had none. For the former three patients, we intervened in a team approach and succeeded in removing the residue from two patients (one with initial correspondence, and the other with execution by the Physical Therapist). Though two patients had fever and inflammatory response one week later, It was hardly possible that aspiration at the time of VF became a direct cause. No patient had either the respiratory or gastrointestinal symptom. Correspondence for aspiration was attained by establishing a team approach system. Even if a patient had heavy aspiration, it was not reflected on chest X-ray films, depending on the case, and therefore deliberation was required for correspondence.

BACKGROUND/AIMS: An interim analysis of post-marketing surveillance of CT-P13, an infliximab biosimilar, was performed to evaluate its safety and efficacy in Japanese patients with inflammatory bowel disease.METHODS: Patients were prospectively enrolled between November 2014 and March 2017, after the launch of CT-P13 in Japan, and case report forms of patients followed for at least 4 months were analyzed as of July 2018.RESULTS: Of 523 patients in the analysis set, 372 remained on CT-P13 therapy, while 54 (20.2%) of 267 patients with Crohn’s disease, and 97 (37.9%) of 256 patients with ulcerative colitis were withdrawn during follow-up. A total of 144 adverse drug reactions (ADRs) were reported in 106 patients (20.3%). Infusion reaction was the most frequent ADR observed in 49 patients (9.4%). Efficacy parameters decreased immediately after the start of treatment in naïve patients to anti-tumor necrosis factor-α antibody. In the patients switched from originator infliximab for nonmedical reasons, the decreased parameters due to proceeded treatment with the originator were maintained in low ranges, and the treatment continuation rate was high with low ADR incidence. In contrast, in patients switched for medical reasons such as adverse event or loss of response, the incidence of ADRs was high. However, the efficacy parameters were improved, and the treatment continuation rate was not significantly different from that of the naïve patient group.CONCLUSIONS: In this interim analysis, CT-P13 was comparable to the originator infliximab with respect to ADRs and efficacy, and is therefore considered to be a cost-efficient interchangeable biosimilar for Japanese patients with inflammatory bowel disease.

BACKGROUND:
Synovial chondromatosis occurs rarely in the shoulder, and its details remain unclear. The purpose of this study was to clarify the clinical results of surgical resection and the histopathological findings of synovial chondromatosis in the shoulder.
METHODS:
Ten shoulders with synovial chondromatosis that had been operatively resected were reviewed retrospectively. Osteochondral lesions were present in the glenohumeral joint in six shoulders and in the subacromial space in four shoulders. Two patients had a history of trauma with glenohumeral dislocation without recurrent instability, and the other seven patients (eight shoulders) did not have any traumatic episodes or past illness involving the ipsilateral shoulder girdle. The occurrences of osteochondral lesions, inferior humeral osteophytes, and acromial spurs were assessed on radiographs before resection, just after resection, and at final follow-up. The Constant scores were compared before resection and at final follow-up with Wilcoxon signed-rank tests. Resected lesions were histopathologically differentiated between primary and secondary synovial chondromatosis.
RESULTS:
Inferior humeral osteophytes were found in five shoulders with synovial chondromatosis in the glenohumeral joint, and all four shoulders with synovial chondromatosis in the subacromial space had acromial spur formation. Osteochondral lesions appeared to have been successfully removed in all shoulders on postoperative radiographs. At the final follow-up, however, one shoulder with secondary synovial chondromatosis in the subacromial space showed recurrence of osteochondral lesions and acromial spur formation. The mean Constant score improved significantly from 53.0 points before resection to 76.0 points at a mean follow-up of 6.0 years (p = 0.002). On histopathological evaluation, one shoulder was diagnosed as having primary synovial chondromatosis, while nine shoulders had secondary synovial chondromatosis.
CONCLUSIONS
The present study showed that resection of shoulder osteochondral lesions successfully relieved the clinical symptoms and that primary synovial chondromatosis is less common than secondary synovial chondromatosis in the shoulder. Although most of the present osteochondral lesions were clinically determined to be primary chondromatosis, only one case was histopathologically categorized as primary synovial chondromatosis. These results suggest that histopathological identification is needed to differentiate between primary and secondary synovial chondromatosis.

Background/Aims:
Mucosal adaptation of the ileum toward colonic epithelium has been reported in pouchitis in ulcerative colitis (UC); however, the clinical characteristics, endoscopic findings, and outcomes in patients with pouchitis with ileal mucosal adaptation are poorly understood.
Methods:
This was a single-center retrospective study comprising UC patients treated by proctocolectomy with ileal pouch-anal anastomosis who had undergone pouchoscopy at the University of Tsukuba Hospital between 2005 and 2022. Endoscopic phenotypes were evaluated according to the Chicago classification. High-iron diamine staining (HID) was performed to identify sulfomucin (colon-type mucin)-producing goblet cells (GCs) in pouch biopsies. We compared clinical data between patients with (high HID group) and without > 10% sulfomucin-producing GCs in at least one biopsy (low HID group).
Results:
We reviewed 390 endoscopic examination reports from 50 patients. Focal inflammation was the most common phenotype (78%). Five patients (10%) required diverting ileostomy. Diffuse inflammation and fistula were significant risk factors for diverting ileostomy. The median proportion of sulfomucin-producing GCs on histological analysis of 82 pouch biopsies from 23 patients was 9.9% (range, 0%–93%). The duration of disease was significantly greater in the high HID group compared to the low HID group. The median percentage of sulfomucin-producing GCs was significantly higher in patients with diffuse inflammation or fistula compared to other endoscopic phenotypes (14% vs. 6.0%, P= 0.011).
Conclusions
Greater proportions of sulfomucin-producing GCs were observed in endoscopic phenotypes associated with poor outcomes in UC, indicating patients with pouchitis showing colonic metaplasia of GCs may benefit from early interventions.

This systematic review aimed to assess the efficacy of the current approach to tissue traction during the endoscopic submucosal dissection (ESD) of superficial esophageal cancer, early gastric cancer, and colorectal neoplasms.We performed a systematic electronic literature search of articles published in PubMed and selected comparative studies to investigate the treatment outcomes of tractionassisted versus conventional ESD. Using the keywords, we retrieved 381 articles, including five eligible articles on the esophagus, 13 on the stomach, and 12 on the colorectum. A total of seven randomized controlled tri-als and 23 retrospective studies were identified. Clip line traction and submucosal tunneling were effective in re-ducing the procedural time during esophageal ESD. The efficacy of traction methods in gastric ESD varied in terms of the devices and strategies used depending on the le-sion location and degree of submucosal fibrosis. Several prospective and retrospective studies utilized traction de-vices without the need to reinsert the colonoscope. When pocket creation is included, the traction devices and methods effectively shorten the procedural time during colorectal ESD. Although the efficacy is dependent on the organ and tumor locations, several traction techniques have been demonstrated to be efficacious in facilitating ESD by maintaining satisfactory traction during dissection.

Inflammatory bowel disease (IBD), including Crohn's disease (CD) and ulcerative colitis (UC), is a chronic inflammatory disease of the gastrointestinal tract, with increasing prevalence worldwide. IBD Ahead is an international educational program that aims to explore questions commonly raised by clinicians about various areas of IBD care and to consolidate available published evidence and expert opinion into a consensus for the optimization of IBD management. Given differences in the epidemiology, clinical and genetic characteristics, management, and prognosis of IBD between patients in Japan and the rest of the world, this statement was formulated as the result of literature reviews and discussions among Japanese experts as part of the IBD Ahead program to consolidate statements of factors for disease prognosis in IBD. Evidence levels were assigned to summary statements in the following categories: disease progression in CD and UC; surgery, hospitalization, intestinal failure, and permanent stoma in CD; acute severe UC; colectomy in UC; and colorectal carcinoma and dysplasia in IBD. The goal is that this statement can aid in the optimization of the treatment strategy for Japanese patients with IBD and help identify high-risk patients that require early intervention, to provide a better long-term prognosis in these patients.

Background/Aims:
The aim of this study was to evaluate the safety of sedation with propofol as an alternative to benzodiazepine drugs in outpatient endoscopy.
Methods:
In this prospective study, examinees who underwent outpatient endoscopy under propofol sedation and submitted a nextday questionnaire with providing informed consent were evaluated. Periprocedural acute responses, late adverse events within 24 hours, and examinee satisfaction were evaluated.
Results:
Among the 4,122 patients who received propofol in the 17,978 outpatient-based endoscopic examinations performed between November 2016 and March 2018, 2,305 eligible examinees (esophagogastroduodenoscopy for 1,340, endoscopic ultrasonography for 945, and total colonoscopy for 20) were enrolled, and their responses to a questionnaire were analyzed. The mean propofol dose was 69.6±24.4 mg (range, 20–200 mg). Diazepam, midazolam, and/or pentazocine in combination with propofol was administered to 146 examinees. Mild oxygen desaturation was observed in 59 examinees (2.6%); and mild bradycardia, in 2 (0.09%). Other severe reactions or late events did not occur. After eliminating 181 invalid responses, 97.7% (2,065/2,124) of the patients desired propofol sedation in future examinations.
Conclusions
Propofol sedation was found to be safe—without severe adverse events or accidents—for outpatient endoscopy on the basis of the patients’ next-day self-evaluation. Given the high satisfaction level, propofol sedation might be an ideal tool for painless endoscopic screening.

Clinical Endoscopy 2021;54(3):363-370
Background/Aims:
Probe-based confocal laser endomicroscopy (pCLE) requires the administration of intravenous (IV) fluorescein. This study aimed to determine the optimal dose of IV fluorescein for both upper and lower gastrointestinal (GI) tract pCLE.
Methods:
Patients 20 to 79 years old with gastric high-grade dysplasia (HGD) or colorectal neoplasms (CRNs) were enrolled in the study. The dose de-escalation method was employed with five levels. The primary endpoint of the study was the determination of the optimal dose of IV fluorescein for pCLE of the GI tract. The reduced dose was determined based on off-line reviews by three endoscopists. An insufficient dose of fluorescein was defined as the dose of fluorescein with which the pCLE images were not deemed to be visible. If all three endoscopists determined that the tissue structure was visible, the doses were de-escalated.
Results:
A total of 12 patients with gastric HGD and 12 patients with CRNs were enrolled in the study. Doses were de-escalated to 0.5 mg/kg of fluorescein for both non-neoplastic duodenal and colorectal mucosa. All gastric HGD or CRNs were visible with pCLE with IV fluorescein at 0.5 mg/kg.
Conclusions
In the present study, pCLE with IV fluorescein 0.5 mg/kg was adequate to visualize the magnified structure of both the upper and lower GI tract.
