RESUMO
Percutaneous endoscopic gastrostomy (PEG) is widely used for long-term enteral nutrition in patients unable to maintain adequate oral intake. Despite advancements in PEG techniques, complications remain a concern. We report a case of a 94-year-old bedridden man who developed significant complications after PEG placement using the pull method. Initially, minor bleeding at the puncture site was managed using traction compression. However, the patient later experienced hemorrhagic shock owing to pulsatile bleeding around the gastrostomy site. Despite attempts to control the bleeding through traction and transfusions, a pseudoaneurysm adjacent to the PEG button was identified. The patient underwent successful transcatheter arterial embolization (TAE). Post-TAE, no further bleeding or hematoma was observed, and imaging confirmed the resolution of the pseudoaneurysm and hematoma. Methicillin-resistant Staphylococcus aureus (MRSA) infection was detected at the gastrostomy site, which contributed to complications. Despite successful management of the bleeding, the patient's overall condition deteriorated, and he died on postoperative day 66. This case underscores the importance of vigilant monitoring and management of PEG-related complications, particularly infections that may precipitate severe vascular events.
RESUMO
We report a case of an 87 year-old woman who was admitted with jaundice, but had no pain or fever. Contrast-enhanced computed tomography revealed a tumor in the head of the pancreas, which caused distal malignant biliary obstruction. Initial transpupillary drainage by endoscopic retrograde cholangiopancreatography (ERCP) was difficult due to severe biliary stricture caused by the tumor, but cannulation of the pancreatic duct was successful. Pancreatic ductal adenocarcinoma was revealed through cytologic examination of pancreatic juice and the patient underwent percutaneous transhepatic biliary drainage (PTBD). 16 days after the jaundice was resolved, an uncovered Zilver® metallic stent was successfully deployed using a guidewire from the PTBD route, and the patient was discharged with palliative care due to advanced age. However, 54 days after discharge, the patient presented with black vomiting and recurrent jaundice. ERCP revealed an obstructed stent with black debris, and further evaluation revealed a ruptured pseudoaneurysm that branched off the gastroduodenal artery within the metallic biliary stent. Angiography revealed that embolization was successful. The patient recovered and was discharged without further episodes.
RESUMO
A 53-year-old woman with a history of recurrent right lower quadrant pain presented with slightly bloody stools in April 2023. She was initially diagnosed with acute diverticulitis using an abdominal computed tomography (CT) scan and was treated conservatively. On the second day, however, she reported significant hematochezia. A subsequent contrast-enhanced CT scan revealed an extravasation in the ascending colon, which was promptly managed with colonoscopy. Despite initial hemostasis, she experienced recurrent bleeding. Another contrast-enhanced CT scan revealed a pseudoaneurysm with ongoing extravasation in the same area. Angiography confirmed a pseudoaneurysm in a branch of the ileocolic artery, which was successfully treated by embolization. She was discharged after an 18 day hospital stay. This case highlights a pseudoaneurysm caused by diverticulitis.

INTRODUCTION: We investigated the factors associated with synchronous multiple early gastric cancers and determined their localization. METHODS: We analyzed 8,191 patients who underwent endoscopic submucosal dissection for early gastric cancers at 33 hospitals in Japan from November 2013 to October 2016. Background factors were compared between single-lesion (n = 7,221) and synchronous multi-lesion cases (n = 970) using univariate and multivariate analyses. We extracted cases with two synchronous lesions (n = 832) and evaluated their localization. RESULTS: Significant independent risk factors for synchronous multiple early gastric cancer were older age (≥75 years old) (odds ratio [OR] = 1.257), male sex (OR = 1.385), severe mucosal atrophy (OR = 1.400), tumor localization in the middle (OR = 1.362) or lower region (OR = 1.404), and submucosal invasion (OR = 1.528 [SM1], 1.488 [SM2]). Depressed macroscopic type (OR = 0.679) and pure undifferentiated histology OR = 0.334) were more common in single early gastric cancers. When one lesion was in the upper region, the other was more frequently located in the lesser curvature of the middle region. When one lesion was in the middle region, the other was more frequently located in the middle region or the lesser curvature of the lower region. When one lesion was in the lower region, the other was more frequently located in the lesser curvature of the middle region or the lower region. CONCLUSION: Factors associated with synchronous multiple early gastric cancer included older age, male sex, severe mucosal atrophy, tumor localization in the middle or lower region, and tumor submucosal invasion. Our findings provide useful information regarding specific areas that should be examined carefully when one lesion is detected.

This case report describes a unique instance of small bowel perforation in a 49-year-old woman caused by an ingested toothpick. Initially suspected of colonic diverticulitis, a final diagnosis of small bowel perforation was made later, and the toothpick was successfully removed via endoscopy. This case emphasizes the need to consider foreign body ingestion in the differential diagnosis of abdominal pain and demonstrates the feasibility of conservative endoscopic approaches in similar cases.
RESUMO
BACKGROUND: Due to the aggressive nature and poor prognosis of advanced pancreatic cancer, prompt initiation of treatment is critical. We investigated the effect of the interval between cancer diagnosis and initiation of chemotherapy on survival in patients with advanced pancreatic cancer. METHODS: In this retrospective, single-centre study, consecutive patients with advanced pancreatic cancer between April 2013 and March 2022 were analyzed. Data were extracted from the electronic medical records of patients who received chemotherapy for metastatic, locally advanced or resectable pancreatic cancer or who received chemotherapy due to either being intolerant of or declining surgery. We compared overall survival between two groups: the early waiting time group (waiting time ≤30 days from diagnosis to chemotherapy initiation) and the elective waiting time group (waiting time ≥31 days). Prognostic factors, including biliary drainage, were considered. The impact of waiting time on survival was assessed by univariate and multivariate analyses with Cox proportional hazard models. A 1:1 propensity score matching approach was used to balance bias, accounting for significant poor prognosis factors, age and sex. RESULTS: The study involved 137 patients. Overall survival exhibited no statistically significant difference between the early and elective waiting time groups (207 and 261 days, P = 0.2518). Univariate and multivariate analyses identified poor performance status and metastasis presence as predictors of worse prognosis. This finding persisted post propensity score matching (275 and 222 days, P = 0.8223). CONCLUSIONS: Our study revealed that initiating chemotherapy Ë30 days later does not significantly affect treatment efficacy compared to within 30 days of diagnosis.

Introduction: Drug-induced liver injury (DILI) associated with 5-aminosalicylic acid (5-ASA) is a rare but potentially life-threatening adverse event. Case Presentation: We report the case of a 58-year-old woman with ulcerative colitis who developed DILI after initiating maintenance therapy with the multimatrix system 5-ASA. The patient presented with grade 4 liver enzyme elevation on day 98 after initiating 5-ASA and was admitted to the hospital. Blood tests revealed the mixed liver injury, and imaging studies showed no abnormalities except for mild lymph node enlargement. Liver biopsy revealed acute lobular hepatitis with interfacial activity. The patient's score on the International Autoimmune Hepatitis Group 1999 revised scoring system was a total score of 10, causing a suspicion for the diagnosis of autoimmune hepatitis. The DDW-J 2004 scale calculated a total score of six, indicating a high probability of DILI. We suspected DILI due to 5-ASA, and the 5-ASA formulations were discontinued. The patient was treated with ursodeoxycholic acid and neominophagen C, and her liver function gradually improved without steroid treatment. Finally, we definitively diagnosed DILI based on the pathological findings and clinical course after discontinuation of 5-ASA. Conclusion: This case highlights the importance of monitoring liver function in patients receiving 5-ASA therapy.
RESUMO
This report describes the case of a 76-year-old man with ulcerative colitis who developed interstitial nephritis after starting 5-Aminosalicylic acid (5-ASA) therapy. The patient experienced an initial improvement in symptoms, but developed fatigue, anorexia, and severe renal dysfunction 2.5 months later. Renal biopsy confirmed drug-induced interstitial nephritis, and conservative treatment with fluid replacement and the discontinuation of 5-ASA improved the patient's condition. Clinicians should monitor patients receiving 5-ASA therapy for potential adverse effects, particularly renal injury, and promptly investigate symptoms of renal dysfunction. Early recognition and discontinuation of the offending agent may prevent further damage and improve patient outcomes.

BACKGROUND: Pancreatic cancer (PC) has a poor prognosis, with body weight loss commonly observed at diagnosis. However, the impact on PC prognosis of weight loss at the time of diagnosis on PC prognosis is unknown. METHODS: This retrospective, single-center study enrolled consecutively patients diagnosed with metastatic or locally advanced PC or resectable PC who were intolerant of or refused surgery. Patients who had lost more than 5% of their body weight or more than 2% and had a body mass index (BMI) of less than 20 kg/m2 at diagnosis were classified as experiencing body weight loss. Patients were subclassified into 2 groups: patients with and without weight loss. The study evaluated patient-related and PC-related factors affecting prognosis. Cox proportional hazards models were used to assess factors affecting prognosis. The primary endpoint was overall survival. Additionally, 1:1 propensity score matching was performed to reduce bias. RESULTS: In total, 220 patients were included in the study. The median age of the patients was 74 years, and 49.1% were male. Weight loss at diagnosis was observed in 43.2% of patients. There were no significant differences in clinical factors, except for anthropometric parameters, between the groups. The median survival time did not differ between the weight loss and no weight loss groups (149 and 173 days, respectively, P = .669). After matching, no significant differences in survival times were observed between the 2 groups. CONCLUSIONS: This study found no association between weight loss at diagnosis and prognosis in patients with advanced PC treated with best supportive care or chemotherapy.

BACKGROUND: The fecal immunochemical test (FIT) is used for colorectal cancer (CRC) screening. Patients on antithrombotic drugs (ATs) are often screened for CRC, but the effect of ATs on FIT results is controversial. METHODS: We divided individuals with FIT-positive results into two groups, patients treated with and without ATs, and retrospectively compared invasive CRC rates, advanced neoplasia detection rates (ANDRs), adenoma detection rates (ADRs), and polyp detection rates (PDRs) between the two groups. We evaluated the factors influencing the FIT positive predictive value (PPV) using propensity matching, adjusting for age, sex, and bowel preparation. RESULTS: We enrolled 2327 individuals (54.9% male; mean age, 66.7â ± â12.7 years). We grouped 463 individuals into the AT user group and 1864 into the nonuser group. Patients in the AT user group were significantly older and more likely to be male. After propensity score matching for age, sex, and Boston bowel preparation scale, the ADR and PDR in the AT user group were significantly lower than those in the nonuser group. Univariate logistic analysis revealed that multiple AT use (odds ratio [OR]: .39, p < 0.001) had the lowest OR for FIT PPV, followed by age- and sex-adjusted factors for the ADR and any AT use (OR: .67, p = 0.0007). No significant factors related to AT use were observed among age-adjusted predictive factors for invasive CRC, but warfarin use was a borderline significant positive predictive factor (OR: 2.23, p = 0.059). CONCLUSION: AT use may not affect the PPV for detecting invasive CRC in patients with positive FIT results, but warfarin may have an impact.
RESUMO
BACKGROUND: GI symptoms are common in acute COVID-19 patients. This study aimed to characterize the GI symptoms occurring in Japanese COVID-19 patients. METHODS: This retrospective single-center cohort study included 751 hospitalized acute COVID-19 patients. The primary outcomes were the frequency and severity of GI symptoms. The secondary outcomes included the association between COVID-19 severity and GI symptoms and the timing of GI symptom onset. RESULTS: After exclusion, the data of 609 patients were analyzed. The median age was 62 years, and 55% were male. The median time from initial symptom onset to admission was five days. On admission, 92% of the patients had fever, 35.1% had fatigue, 75% had respiratory symptoms, and 75% had pneumonia. The sample included patients with mild (19%), moderate (59%), and severe COVID-19 (22%). A total of 218 patients (36%) had GI symptoms, of which 93% were classified as grade 1/2; 170 patients had both respiratory and GI symptoms. Diarrhea was the most frequent GI symptom, occurring in 170 patients, followed by anorexia in 73 patients and nausea/vomiting in 36 patients, and abdominal pain in 8 patients. There was no significant relationship between COVID-19 severity and GI symptoms. Among COVID-19 patients with both GI and respiratory symptoms, 48% had respiratory symptoms preceding GI symptoms, 25% had GI symptoms preceding respiratory symptoms and 27% had a simultaneous onset of respiratory and GI symptoms. CONCLUSION: Thirty-six percent of the Japanese COVID-19 patients had GI symptoms; diarrhea was the most frequent GI symptom but did not predict severe COVID-19.

BACKGROUND AND AIM: Cold snare polypectomy is commonly performed to remove small colorectal polyps. Accidental resection of carcinomas during this procedure has been reported. Herein, we aimed to clarify the clinicopathological features and clinical course of colorectal carcinomas resected by cold snare polypectomy. METHODS: This multicenter retrospective cohort study was conducted at 10 Japanese healthcare centers. Of the colorectal lesions resected by cold snare polypectomy between April 2016 and March 2020, lesions pathologically diagnosed as carcinoma were reviewed. Centralized histology (based on the Vienna classification) and endoscopic reviews were performed. The study endpoints were endoscopic features and clinical outcomes of cold snare polypectomy-resected colorectal carcinomas (Vienna category ≥4.2). RESULTS: We reviewed 74 of the 70 693 lesions resected by cold snare polypectomy. After a central pathological review, 68 lesions were diagnosed as carcinomas. The Japan Narrow-band imaging Expert Team (JNET) classification type 2B, lesion size ≥6 mm, and multinodular morphology were the significant endoscopic predictors of carcinoma resected by cold snare polypectomy. No adverse events related to the procedure occurred. Sixty-three lesions were diagnosed as carcinomas within the mucosal layer, and 34 were curative resections. Of the five carcinoma lesions with submucosal invasion, additional surgery revealed remnant cancer tissues in one lesion. No local or metastatic recurrence was observed during follow-up. CONCLUSIONS: Although most of the carcinomas resected by cold snare polypectomy were within the mucosal layer, few lesions invading the submucosa were identified. Careful pre-procedural endoscopic evaluation, especially focusing on the JNET classification and multinodular morphology, is recommended.

BACKGROUND AND AIMS: Data are lacking regarding post-endoscopic submucosal dissection (ESD) bleeding in patients with early gastric cancer (EGC) who take antiplatelet agents (APAs), particularly in those taking thienopyridine and cilostazol. We aimed to clarify the association between the status of APA medication and post-ESD bleeding risk. METHODS: This study is a secondary analysis using data from a recently conducted nationwide multicenter study in Japan. We retrospectively reviewed patients treated with APAs or on no antithrombotic therapy recruited from 33 institutions who underwent ESD for EGC between November 2013 and October 2016. The primary outcome of this study was the relationship between the rate of post-ESD bleeding and the status of each APA medication. RESULTS: A total of 9736 patients were included in the analysis. Among 665 aspirin users, the continuation group was significantly associated with post-ESD bleeding (odds ratio [OR], 2.79; 95% confidence interval [CI], 1.77-4.37). Among 227 thienopyridine users, the aspirin or cilostazol replacement group was not significantly associated with post-ESD bleeding (OR, 1.85; 95% CI, .72-4.78). Among 158 cilostazol users, there was no significant association with post-ESD bleeding, irrespective of medication status. The rate of post-ESD bleeding was approximately 10% to 20% irrespective of the status of APA administration among dual-antiplatelet therapy users. No patients experienced thromboembolic events in this study. CONCLUSIONS: Replacement of thienopyridine with aspirin or cilostazol may be acceptable for minimizing both the risk of post-ESD bleeding and thromboembolism in patients with EGC. In patients on cilostazol monotherapy undergoing ESD, continuation of therapy may be acceptable.

BACKGROUND AND AIM: Oxaliplatin can lead to hepatic sinusoidal injury, called hepatic sinusoidal obstruction syndrome (SOS), resulting in portal hypertension-related complications. This could worsen the clinical course of the patients treated with oxaliplatin. Early diagnosis is challenging. We explored predictive markers of oxaliplatin-induced collateral vessels. METHODS: Patients who received oxaliplatin-based chemotherapy were retrospectively screened. We evaluated their laboratory findings and spleen size on computed tomography immediately before oxaliplatin-based chemotherapy and after 6 months of treatment. The primary outcome was collateral vessel development, as a surrogate marker for oxaliplatin-induced SOS in patients who underwent oxaliplatin-based chemotherapy. The secondary outcome was the identification of factors that predicted the development of collateral vessels. RESULTS: We enrolled 161 patients who received oxaliplatin-based chemotherapy. They had a median age of 69 years, and 63.3% were men. Collateral vessels developed in nine (5.6%) patients during the study period. After oxaliplatin-based chemotherapy, the spleen size increased in 104 patients (64.6%), with a ≥ 30% increase in 19.4% of the patients. Univariate analysis showed that the Fibrosis-4 (FIB-4) index (≥ 1.76; OR 9.17), aspartate aminotransferase:platelet ratio index (APRI) (≥ 0.193; OR 9.62), cumulative dose of oxaliplatin (≥ 1000 mg; OR 8.43), and increase in spleen size (≥ 30%; OR 6.01) were significant risk factors for collateral vessel development. Multivariate analysis after stepwise selection revealed that the FIB-4 index and spleen size were significant independent predictive factors. CONCLUSION: A ≥ 1.76 increase in the FIB-4 index and a ≥ 30% increase in spleen size after 6 months of oxaliplatin-based chemotherapy were significant predictive markers for collateral vessel development.

BACKGROUND: Although the combination of conventional endoscopy (CE) and endoscopic ultrasonography (EUS) is useful for predicting the depth of early gastric cancer (EGC), the diagnostic value of EUS for submucosal (SM) invasive cancer has not been fully investigated. METHODS: We conducted a multicenter prospective study from May 2017 to January 2021 to evaluate the validity of a diagnostic strategy combining CE and EUS and to clarify the additional value of EUS for EGC suspected of SM invasion. In each case, the diagnosis was first made using CE, followed by EUS, and finally confirmed using a combination algorithm. RESULTS: A total of 180 patients with EGC were enrolled from 10 institutions, of which 175 were analyzed. The histopathological depths were M, SM1, SM2, and ≥ MP in 72, 16, 64, and 23 lesions, respectively. Treatment included 92 endoscopic submucosal dissection cases and 83 surgical cases. The overall diagnostic accuracy classified by M-SM1 or SM2-MP was 58.3% for CE, 75.7% for EUS, and 78.9% for the combination of CE and EUS; the latter two were significantly higher than that of CE alone (P < 0.001). The CE, EUS, and combination accuracy rates in 108 differentiated-type lesions were 51.9%, 77.4%, and 79.6%, respectively; the latter two were significantly higher than CE alone (P < 0.001). A significant additive effect of EUS was observed in CE-SM2 low-confidence lesions but not in CE-M-SM1 lesions or in CE-SM2 high-confidence lesions. Among the nine CE findings, irregular surface, submucosal tumor-like elevation, and non-extension signs were significant independent markers of pSM2-MP. Poorly delineated EUS lesions were misdiagnosed. CONCLUSIONS: EUS provides additional value for differentiated-type and CE-SM2 low-confidence EGCs in diagnosing invasion depth.

BACKGROUND: Predicting the risk of malignant transformation in pancreatic cyst patients is challenging. AIM: We retrospectively investigated the risk factors for malignant transformation in pancreatic cyst patients. METHODS: Patients with pancreatic cysts diagnosed using imaging tests were followed from November 2008 to December 2021. A significant change was defined as the additional development of high-risk stigmata (HRS), worrisome features (WFs), or pancreatic cancer during monitoring. RESULTS: In total, 479 patients were analyzed, with a median observation period of 50 months. Forty-four patients (9.2%) showed significant changes, and eight (1.7%) developed pancreatic cancer. The univariate analysis showed that the cyst diameter at diagnosis (≥ 14 mm), main pancreatic duct (MPD) diameter at diagnosis (≥ 3 mm), presence of multilocular cysts, and an inconsistent MPD caliber were significant predictive factors for a significant change. One point was assigned for each significant factor. We grouped the patients into three groups: the low-risk group (total score 0), medium-risk group (score 1-2), and high-risk group (score 3-4). The high-risk group had a higher risk of a significant change than the medium- and low-risk groups (age-adjusted HRs for the medium-risk and high-risk groups were 3.0 and 5.2 compared with the low-risk group). CONCLUSION: Stratification based on risk factors may help predict the development of significant changes in pancreatic cyst patients.

INTRODUCTION: Few studies have focused on bleeding following endoscopic submucosal dissection (ESD) in surgically altered stomach. We aimed to reveal the bleeding risk in surgically altered stomach following ESD for early gastric cancer (EGC). METHODS: We enrolled patients with ESD for EGC at 33 institutions between 2013 and 2016. In study 1, we evaluated bleeding risk following ESD in surgically altered stomach, compared with whole stomach. In study 2, we evaluated factors associated with bleeding following ESD in patients with surgically altered stomach. RESULTS: Of 11,452 patients, 445 patients had surgically altered stomach with the bleeding rate following ESD of 4.9%. In study 1, the bleeding risk in surgically altered stomach was not significant (odds ratio [OR], 1.37; 95% confidence interval [CI], 0.87-2.17) in the multivariate logistic regression analysis. No significant results were obtained when the surgically altered stomach was subdivided into various types. In study 2, the multivariate logistic regression analysis revealed that independent risk factors for bleeding following ESD were ischemic heart disease (OR, 7.52; 95% CI, 2.00-28.25) and P2Y12 receptor antagonist (OR, 4.81; 95% CI, 1.21-19.14). DISCUSSION/CONCLUSION: In this nationwide study, we found that the bleeding risk of surgically altered stomach following ESD for EGC did not significantly differ from that of whole stomach. The risk factors for ESD in patients with surgically altered stomach were ischemic heart disease and P2Y12 receptor antagonist.

Recently, direct oral anticoagulants (DOACs) have been widely used as antithrombotic agents to replace warfarin, but their clinical impact in patients with gastrointestinal bleeding is unclear. We compared the effects of warfarin and DOACs on the outcomes of patients with colonic diverticular bleeding. The patients were divided into warfarin and DOAC groups. We compared the clinical outcomes and the effect of the DOAC dosing and examined any readmissions due to colonic diverticular bleeding within 1 year. A total of 95 events (warfarin group: n = 43 and DOAC group: n = 52) were included. Compared with the warfarin group, the DOAC group was significantly older, had a lower rate of concomitant antiplatelet agents, and a shorter hospital stay, but no significant differences were found in the other clinical outcomes. Thirty-seven patients (71.2%) in the DOAC group had appropriate dosing, whereas 15 patients (28.9%) had an inappropriate dose. The patients with overdose or contraindications had significantly lower minimum hemoglobin levels. In the univariate analysis, prior hospitalization for colonic diverticular bleeding was a significant predictor of readmission. Compared with warfarin, patients with colonic diverticular bleeding treated with DOACs were older and had shorter hospital stays, and the inappropriate use of DOACs may worsen outcomes.

BACKGROUND AND AIM: Sessile serrated lesions (SSLs) act as precursors to colorectal cancer, sometimes harbor carcinomas, and are sometimes incompletely resected. We aimed to evaluate local recurrence after endoscopic resection of SSL ≥10 mm. METHODS: This prospective, single-arm, observational study was performed at eight Japanese tertiary institutions. Colorectal lesions ≥10 mm were resected endoscopically, and the pathological diagnosis was either an SSL or hyperplastic polyp (HP). Follow-up colonoscopy was performed 1 year later, and the local recurrence was evaluated by biopsy. RESULTS: From October 2018 to September 2021, 104 cases with 123 lesions were registered. Among the pathologically diagnosed 105 SSLs and 18 HPs, 95 and 7 lesions were diagnosed as SSLs and HPs, respectively, by central pathological review. Among the 104 endoscopically diagnosed SSLs, 86 were diagnosed as SSLs, whereas among the 11 endoscopically diagnosed HPs, two were diagnosed as HPs by central pathological review (the rest were SSLs). Among the 95 patients with 113 lesions who underwent follow-up colonoscopy, resection scars were identified in 95 (84%) lesions. Three (3.1%; 95% confidence interval 0.6-8.7%) local recurrences were diagnosed pathologically among 98 pathologically diagnosed SSLs. Two (6%) local recurrences were diagnosed in patients with SSLs ≥20 mm. CONCLUSIONS: The local recurrence rate after endoscopic resection of SSLs ≥10 mm was 3.1%. Careful follow-up is recommended after endoscopic resection of large SSLs. Endoscopically diagnosed HPs ≥10 mm were sometimes pathologically diagnosed as SSL and should be considered for resection.

Objective Treatment for uncomplicated diverticulitis (UD) is not well established. We evaluated the strategy of reviewing intravenous antibiotics for hospitalized Japanese patients with UD. Methods Treatment was based on the physician's choice until August 2018; the indications for hospitalization and treatment have been standardized since September 2018. In this study, we monitored the use of intravenous antibiotics administered to patients hospitalized for UD and then reviewed the need for them on hospital day 3. We compared patients' length of antibiotic use, hospital stay, health care cost, and complications via the review strategy from September 2018 to December 2020 and via the previous physicians' choice strategy from January 2016 to August 2018. Results Two hundred and forty-seven patients were admitted to our hospital because of acute colonic diverticulitis from January 2016 to December 2020. After excluding complicated cases, 106 individuals were enrolled during the period of physician's choice; 87 were enrolled when treatment review was employed. There were no significant differences in age, sex, inflammation site, or severity during the first hospital visit. The median duration of antibiotic use was significantly reduced from 5 to 4 days (p=0.0075), with no marked increase in rates of transfer to surgery, mortality, or readmission due to recurrence. A more significant proportion of patients completed 3-day antibiotic treatment with the review strategy than with the physician's choice strategy (6.6% vs. 25.3%, p=0.0004). However, the length of hospital stay and total medical costs did not decrease. Conclusion The strategy of reviewing treatment on day 3 after hospitalization for UD safety reduced the duration of antibiotic use, but the hospital stay and health care costs did not decrease.
