OBJECTIVE: This study aimed to investigate whether a novel, easy loop-forming guidewire could reduce post-endoscopic retrograde cholangiopancreatography pancreatitis (PEP) in patients undergoing endoscopic nasopancreatic drainage tube placement for serial pancreatic juice aspiration cytologic examination (SPACE). METHODS: We evaluated patients with suspected pancreatic cancer who underwent SPACE at our institution between January 2015 and April 2023 retrospectively. The patients were divided into 2 groups based on the type of guidewire used, namely, easy loop-forming and control groups. Propensity score matching was used to compare the incidence of PEP between the groups. RESULTS: We included 101 patients, with 51 and 50 in the easy loop-forming and control groups, respectively. After propensity score matching, 29 pairs of patients were selected from each group. Intraductal ultrasonography of the pancreas was performed more frequently in the easy loop-forming group than in the control group (27.6% vs 0%; P = 0.004); however, PEP incidence was significantly lower in the easy loop-forming group than in the control group (3.4% vs 27.6%; odds ratio, 0.097; 95% confidence interval, 0.002-0.82; P = 0.025). CONCLUSIONS: The use of the novel easy loop-forming guidewire decreased PEP occurrence in patients who underwent endoscopic nasopancreatic drainage tube placement for SPACE.

BACKGROUND AND AIMS: Endoscopic placement of self-expandable metal stents (SEMSs) for malignant distal biliary obstruction (MDBO) may be accompanied by several types of adverse events. The present study analyzed the adverse events occurring after SEMS placement for MDBO. METHODS: The present study retrospectively investigated the incidence and types of adverse events in patients who underwent SEMS placement for MDBO between April 2018 and March 2021 at 26 hospitals. Risk factors for acute pancreatitis, cholecystitis, and recurrent biliary obstruction (RBO) were evaluated by univariate and multivariate analyses. RESULTS: Of the 1425 patients implanted with SEMSs for MDBO, 228 (16.0%) and 393 (27.6%) experienced early adverse events and RBO, respectively. Pancreatic duct without tumor involvement (P = .023), intact papilla (P = .025), and SEMS placement across the papilla (P = .037) were independent risk factors for acute pancreatitis. Tumor involvement in the orifice of the cystic duct was an independent risk factor for cholecystitis (P < .001). Use of fully and partially covered SEMSs was an independent risk factor for food impaction and/or sludge. Use of fully covered SEMSs was an independent risk factor for stent migration. Use of uncovered SEMSs and laser-cut SEMSs was an independent risk factor for tumor ingrowth. CONCLUSIONS: Pancreatic duct without tumor involvement, intact papilla, and SEMS placement across the papilla were independent risk factors for acute pancreatitis, and tumor involvement in the orifice of the cystic duct was an independent risk factor for cholecystitis. The risk factors for food impaction and/or sludge, stent migration, and tumor ingrowth differed among types of SEMSs.

A 74-year-old man with severe osteogenesis imperfecta (OI) was admitted to our hospital because of repetitive cholecystitis due to a stone in the gallbladder neck. Because he had severe OI-related chest wall deformity and a high risk of complications from bronchial intubation, general anesthesia, and surgery, we performed endoscopic ultrasound-guided gallbladder drainage (EUS-GBD). The postprocedural clinical course was uneventful, and he was discharged in satisfactory condition. EUS-GBD is a treatment option for acute cholecystitis in surgically high-risk patients with OI. However, special attention should be paid to the influence of sedation on the respiratory and cardiovascular systems during the procedure.
RESUMEN
We present the case of a 72-year-old woman with elevated hepatobiliary enzymes and a small mass in the distal bile duct near the papilla. Fluoroscopy-guided forceps biopsy initially yielded insufficient tissue. After endoscopic papillary large balloon dilation with sphincterotomy, a stone retrieval balloon was used to expose the tumor to the duodenum. Biopsy under direct visualization using standard forceps revealed adenocarcinoma. The technique may be useful for the biopsy of lesions located in the terminal segment of the distal bile duct.

Endoscopic transpapillary gallbladder stenting is sometimes inhibited by a cystic duct loop, necessitating cystic duct straightening. Mandai and colleagues report a novel technique for straightening the looped cystic duct using a fine-gauge balloon dilator, which is useful during endoscopic gallbladder stenting when the double-guidewire technique fails.

BACKGROUND: Techniques and devices for endoscopic ultrasound (EUS)-guided hepaticoenterostomy (EUS-HES) procedures, including EUS-guided hepaticogastrostomy (EUS-HGS) and EUS-guided hepaticojejunostomy (EUS-HJS), have been developed; however, the optimal timing to begin oral intake after EUS-HES remains unknown. This study aimed to evaluate the safety of early oral intake after EUS-HES. METHODS: We retrospectively investigated patients who underwent EUS-HES (EUS-HGS or EUS-HJS) between March 2015 and March 2022. Patients who had no problems with the results of blood tests and computed tomography examinations on the morning of day 1 after EUS-HES were classified as either the early intake group (started oral intake on day 1 after EUS-HES) or the late intake group (started oral intake on day 2 or later after EUS-HES). Patients' characteristics, procedure characteristics, and early postprocedural adverse events (within 14 days after the procedure) were compared between groups. RESULTS: Fifty patients were enrolled in this study. Forty-three patients had no problems with the results of examinations performed on the morning of day 1 after EUS-HES. Twenty-one patients comprised the early intake group and 22 comprised the late intake group. Adverse events that developed within 14 days after EUS-HES were not significantly different between groups (early 4.7% vs. late 9.0%; odds ratio, 0.50; 95% confidence interval, 0.0080-10.49; P = 1.00). CONCLUSIONS: Starting oral intake on day 1 after EUS-HES did not increase postprocedural adverse events compared with starting oral intake on day 2 or later after EUS-HES.

Synovial sarcoma is a malignant soft tissue tumor that often occurs near the limb joints. Here, we report a case of a patient with a synovial sarcoma that occurred in the mediastinum. The initial pathological diagnosis was suspected angiofibroma after surgical resection. After surgery, the tumor recurred in the pericardium and caused cardiac tamponade. Pericardial fenestration was performed and the patient was diagnosed with synovial sarcoma. The final diagnosis was the postoperative pericardial recurrence of the mediastinal synovial sarcoma. It is important to consider follow-up on the basis of the malignant tumor, especially if the disease is rare.
RESUMEN
Conventional gallbladder re-intervention along the naso-gallbladder drainage tube may result in dislocation of the tube during scope insertion or failure of guidewire insertion into the gallbladder. Mandai et al report a simple method for transferring a transpapillary naso-gallbladder drainage tube to the mouth that facilitates reliable re-intervention for gallbladder lesions.

BACKGROUND/PURPOSE: Whether a fully covered self-expanding metal stent (FCSEMS) or plastic stent (PS) is preferable for preoperative biliary drainage in patients with resectable pancreatic cancer (RPC) is controversial. This study aimed to evaluate the safety and efficacy of drainage with FCSEMS for obstructive jaundice caused by RPC without neoadjuvant chemotherapy. METHODS: Seventy patients with RPC who required preoperative biliary drainage were randomly assigned 1:1 to the FCSEMS or PS group. The primary endpoint was endoscopic re-intervention rate during the waiting period for surgery. Secondary endpoints were drainage procedure time, drainage-related adverse events (AE), waiting period for surgery, operative time, intraoperative blood loss, surgery-related AE, and postoperative hospital stay. RESULTS: Thirty-nine patients underwent surgery. None required re-intervention in the FCSEMS group, whereas five PS patients underwent re-intervention (P = .023). The FCSEMS group had significantly more intraoperative blood loss (P = .0068) and AE (P = .011) than the PS group. Postoperative hospital stay was significantly longer in the FCSEMS group (P = .016). CONCLUSIONS: Fully covered self-expanding metal stent had a lower rate of endoscopic re-intervention during the waiting period for surgery than PS, but showed more intraoperative blood loss, higher incidence of surgery-related AE, and longer postoperative hospital stays.
