RESUMEN
A female patient in her 50s who underwent chemotherapy for left primary breast cancer presented with cancerous pleurisy and disseminated intravascular coagulation. Esophagogastroduodenoscopy and liver biopsy revealed gastric and liver cancer. Distinguishing between primary and metastatic cancer by pathological findings is difficult using hematoxylin and eosin staining. We diagnosed and treated simultaneous primary breast cancer (ER-positive) and gastric cancer with liver metastasis (ER-negative), based on differences in estrogen receptor expression. The patient lived for 10 months with chemotherapy. After death, an autopsy was performed because the endoscopic results were atypical for primary gastric cancer, and additional immunohistochemical studies indicated gastric metastasis of breast cancer.

BACKGROUND AND AIMS: Although long-term stent placement using endoscopic transpapillary gallbladder drainage (ETGBD) and EUS-guided gallbladder drainage (EUS-GBD) reportedly reduces cholecystitis recurrence, comparative evidence of their safety and efficacy is scarce. This study aimed to examine and compare the long-term utility of EUS-GBD versus that of ETGBD in poor surgical candidates. METHODS: A total of 379 high-risk surgical patients with acute calculous cholecystitis met the eligibility criteria for enrollment in this study. The technical success and adverse events (AEs) were compared between the EUS-GBD and ETGBD groups, and propensity score matching was performed to adjust for differences between the groups. Both groups underwent plastic stent placement, and scheduled stent exchange and removal were not performed in either group. RESULTS: The technical success rate of EUS-GBD was significantly higher than that of ETGBD (96.7% vs 78.9%, P < .001), whereas the early AE rate did not differ significantly between the 2 methods (7.8% vs 8.9%, P = 1.000). The rate of recurrent cholecystitis did not differ significantly (3.8% vs 3.0%, P = 1.000), but the rate of symptomatic late AEs, in addition to cholecystitis, was significantly lower with EUS-GBD than with ETGBD (1.3% vs 13.4%, P = .006). Consequently, the overall late AE rate was significantly lower with EUS-GBD (5.0% vs 16.4%, P = .029). Multivariate analysis revealed that EUS-GBD was associated with a significantly longer time to late AE (hazard ratio, .26; 95% confidence interval, .10-.67; P = .005). CONCLUSIONS: Long-term stent placement via EUS-GBD is a promising potential option for limiting late AEs, including recurrence, in poor surgical candidates with calculous cholecystitis.

BACKGROUND: Although long-term stent placement using endoscopic gallbladder stenting (EGBS) reportedly reduces cholecystitis recurrence in patients unfit to undergo cholecystectomy, its efficacy and safety remain uncertain. AIMS: This study aimed to examine the long-term effect of EGBS in poor surgical candidates of cholecystectomy. METHODS: A total of 528 high-risk surgical patients with acute calculous cholecystitis met this study's eligibility criteria. The technical success and adverse events (AE) were compared between patients who underwent EGBS and those who underwent percutaneous transhepatic gallbladder drainage (PTGBD). Elective stent exchange and removal were not performed after EGBS. The external tube was removed after improvement of cholecystitis following PTGBD. RESULTS: The technical success rate was significantly lower with EGBS compared to PTGBD (75.4% versus 98.7%, P < 0.001), while the early-AE rate did not differ significantly between the two methods (7.7% versus 4.3%, P = 0.146). The 1-, 3-, and 5-year cumulative incidence rates of cholecystitis were 3.8%, 7.2%, and 7.2% with EGBS, and 11.7%, 17.6%, and 30.2% with PTGBD, respectively (P = 0.001). Conversely, those of symptomatic late-AE (except cholecystitis) were 8.2%, 22.7%, and 31.4% with EGBS, and 7.5%, 10.9%, and 13.1% with PTGBD, respectively (P = 0.035). Thus, the 1-, 3-, and 5-year cumulative incidence of overall late-AE was 12.0%, 30.4%, and 40.4% with EGBS, and 19.2%, 28.3%, and 42.5% with PTGBD, respectively (P = 0.649). CONCLUSIONS: Long-term stent placement via EGBS is useful for preventing the recurrence of cholecystitis, but the success rate is low and the frequency of other late-AE increases with the prolongation of the indwelling period.

A female patient in her 60s, treated with oral corticosteroids for scleroderma diagnosed 11 years ago, visited our hospital complaining of a persistent fever and liver dysfunction. She was treated with antibiotics, but her fever continued. Abdominal ultrasonography revealed multiple hypoechoic splenic masses. Splenic masses revealed multiple masses with no contrast effect in arterial and portal phases and nuclear in equilibrium phase by contrast computed tomography study, as well as hyperintensity masses with low signal areas in magnetic resonance imaging T2-weighted images. Liver tissue was obtained by percutaneous liver biopsy, and histological findings showed epithelioid cell granulomas without tumor cells. Further interview and physical examination revealed scratch scars from domestic cats and left axillary lymph node swelling. Hence, a cat scratch disease was suspected. She was diagnosed with cat scratch disease by serum indirect immunofluorescence. Her fever was resolved with minocycline administration. Therefore, persistent fever with splenic masses should be suspected of hepatosplenic cat scratch disease.

BACKGROUND AND AIM: Two methods of transpapillary covered self-expandable metal stent (SEMS) placement are used for distal malignant biliary obstruction (MBO): after initial drainage by plastic stent (two-step method) and without previous drainage (one-step method). METHODS: In total, 90 patients with unresectable pancreatic cancer and distal MBO were enrolled in this prospective multicenter randomized study and allocated to one-step (n = 45) and two-step (n = 45) groups. The main outcome was the time to recurrent biliary obstruction (TRBO). Secondary outcomes were the rates of early and late adverse events, survival time, the time required for bilirubin level reduction, and cost-effectiveness. RESULTS: The median TRBO did not differ significantly between the one-step and two-step groups (not available vs 314 days, P = 0.134). SEMS migration occurred significantly more frequently in the two-step group (14.3% vs 0%, P = 0.026). No significant difference was observed between groups in early (7.3% vs 14.3%, P = 0.483) or late (12.2% and 11.9%, P = 1) adverse events other than RBO, survival time (P = 0.104), or the median number of days required to reach a bilirubin level considered to be acceptable for chemotherapy administration (<3 mg/dL; P = 0.881). The total costs of stent placement and reintervention were significantly lower in the one-step SEMS group (3347 vs 5465 US dollars, P < 0.001). CONCLUSIONS: The superiority of TRBO with two-step SEMS placement was not demonstrated. One-step SEMS placement might be a promising method from the viewpoints of cost-effectiveness and less invasiveness (UMIN-CTR clinical trial registration number: UMIN000016010).

BACKGROUND: The recent development of ultra-thin delivery systems, which enable simultaneous insertion of two metal stents, has encouraged wider adoption of side-by-side (SBS) stent placement for malignant hilar biliary obstruction (MHBO). However, the management of stent occlusion after SBS placement has not been well-characterized. This study aimed to examine the outcomes of endoscopic reintervention (E-RI) after SBS placement in patients with MHBO. METHODS: Sixty-seven patients who underwent E-RI for stent occlusion after SBS placement between 2013 and 2020 at three tertiary-care referral centers were investigated. We evaluated the technical success, clinical success, recurrent biliary obstruction (RBO), and adverse events other than RBO rates associated with E-RI. Furthermore, the factors associated with successful E-RI were also evaluated. RESULTS: The technical success and clinical success rates were 79.1% (53/67) and 76.1% (51/67), respectively. Early adverse events other than RBO occurred in 4.5% (3/67) and late events in 3.9% (2/51). The RBO rate after E-RI was 52.9% (27/51), and the median time to RBO after E-RI was 85 days. Common bile duct (CBD) diameter (odds ratio 2.62; 95% confidence interval, 1.37-5.01; P = 0.003) and metastatic disease (odds ratio, 0.11; 95% confidence interval, 0.02-0.64; P = 0.015) were independently correlated with E-RI success in the multivariate analysis. CONCLUSIONS: This study demonstrated that E-RI after SBS placement is technically feasible and safe, but the success rate was significantly lower in patients with narrow CBDs and metastatic diseases. These factors may be useful for the selection of the initial stenting method.

A 38-year-old man visited our hospital with a complaint of diarrhea and abdominal pain. Contrast-enhanced computed tomography showed that the ileocecal site was intussuscepted to the transverse colon without ischemia. After we reduced intussusception with an enema using a water-soluble contrast agent, his abdominal pain disappeared. Colonoscopy was performed immediately after reduction and showed erosion and edema at the ileocecal site without tumor. The stool culture at admission revealed verotoxin 1 producing Escherichia coli O-26;therefore, we established a diagnosis of intussusception associated with Escherichia coli enterocolitis. Bacterial enteritis should be considered as a potential cause in adult patients with intussusception.

OBJECTIVE: Diverticular bleeding is the most common cause of acute lower gastrointestinal bleeding, and its incidence has recently increased. However, the treatment strategy of diverticular bleeding has not yet been established. The aim of the study was to investigate the efficacy of contrast-enhanced computed tomography (CECT) to determine the indication for urgent colonoscopy to achieve hemostasis. METHODS: A total of 124 patients diagnosed with diverticular bleeding between 2012 and 2013 in our hospital were analyzed. The clinical behavior, factors related to detecting bleeding diverticula, and risk factors for early rebleeding of diverticular bleeding were evaluated. RESULTS: Clinical behavior: Bleeding diverticula were identified in 23 of 124 (19%) patients and most of them (16/23; 70%) were located in the ascending colon. Hemostasis was achieved in all 23 cases, however, six (26%) developed early rebleeding. Factors for detecting bleeding diverticula: In patients in whom extravasation was detected using CECT, the endoscopic detection rate of bleeding diverticula was 60% (12/20), while bleeding diverticula were detected in only 31% (11/35) of patients in whom extravasation was not detected using CECT (p<0.05). The interval between the first hematochezia and colonoscopy in which the bleeding point was detected by colonoscopy (median 23.5 hours) was shorter than that in which bleeding diverticula were not detected (median 43.6 hours) (p<0.01). Risk factors for short term rebleeding: Using a univariate analysis, atherosclerotic comorbidity, anti-inflammatory drugs including low-dose aspirin, antithrombotic agents, vital signs on admission, hemoglobin level on hospitalization, and extravasation on CECT were not found to be significant risk factors. CONCLUSION: The finding of extravasation on CECT is the most important factor for identifying and treating bleeding diverticula by colonoscopy. In such cases, urgent colonoscopy is recommended.
