Introduction: Several diagnostic and therapeutic endoscopic urological procedures, such as stent placement, ureteroscopy, and bladder stone lithotripsy, can be performed in a hospital, an ambulatory surgery center, in the office with IV sedation, or in the office using only topical anesthesia. The potential benefits of performing procedures in the office setting using topical anesthesia include efficiency and cost reduction. The potential harms are failure to achieve the desired outcome and patient pain. The purpose of our study was to assess the feasibility, safety, pain tolerance, and cost-effectiveness of advanced office endourological procedures. Methods: All patients from September 2022 to July 2023 undergoing certain office-based endoscopic procedures under topical anesthesia, including ureteral stent placement for obstruction, ureteral stent exchange, ureteroscopy with laser lithotripsy, ureteroscopy with tumor ablation, laser ablation of multifocal bladder tumors, laser lithotripsy of bladder stones, nephrostomy tube exchange, and ureteral catheterization for chemotherapy instillation or retrograde ureteropyelography, were prospectively enrolled and evaluated. At the end of every procedure, visual analog scale (VAS) score and procedure location preference were assessed. Complications and facility costs were also assessed. Results: A total of 80 endoscopic procedures were performed, including 11 bladder procedures, 9 ureteroscopies, and 60 stent and nephrostomy procedures. The mean VAS pain score for bladder procedures was 2.4, ureteroscopy procedures 3.9, and stent and nephrostomy procedures 3.3. Patients undergoing bladder and stent/nephrostomy procedures unanimously expressed a preference for the in-office setting. The office setting was also largely preferred in the ureteroscopy procedure cohort (77.8%). There were eight postprocedure calls and two ED visits. One complication and one failed stent placement occurred. Procedure cost savings ranged from $5,309 to $6,009. Conclusions: Performing certain endoscopic urological procedures in an office setting with only the use of topical anesthesia is feasible, safe, well tolerated, and cost-effective when compared with performing these procedures in the operating room or with general anesthesia.

The aim of this study was to explore the impact of anesthetic drugs currently used to perform lower digestive endoscopy on serum concentrations of inflammation markers and catecholamines. We selected 120 patients and divided them into three lots of 40 patients each: L1, in which no anesthetics were used; L2, in which propofol was used; and L3, in which propofol combined with fentanyl was used. All patients had serum concentrations of adrenaline/epinephrine (EPI), noradrenaline/norepinephrine (NE), tumor necrosis factor alpha (TNF-α), interleukin-4 (IL-4), IL-6, IL-8, and IL-10, taken at three time points: at the beginning of the endoscopic procedure (T0), 15 min after (T1), and 2 h after the end of the endoscopic procedure (T2). The results of the research showed changes in the levels of catecholamines and interleukins (ILs) at T0, with an increased response in L1 above the mean recorded in L2 and L3 (p < 0.001). At T1, increased values were recorded in all lots; values were significantly higher in L1. At T2, the values recorded in L3 were significantly lower than the values in L2 (student T, p < 0.001) and L1, in which the level of these markers continued to increase, reaching double values compared to T0 (student T, p < 0.001). In L2 at T1, the dose of propofol correlated much better with NE, EPI, and well-known cytokines. Our results show that propofol combined with fentanyl can significantly inhibit the activation of systemic immune and neuroendocrine response during painless lower digestive endoscopy.

Introduction. Pituitary tumours are usually benign adenomas. Surgical treatment is most often dedicated to patients with adenomas that cause symptoms of pressure, such as visual disturbances, headaches or symptoms resulting from hormonal disorders. Aim. The aim of this study is to present the characteristic problems of a patient with pituitary macroadenoma who underwent endoscopic surgery through the sphenoid sinus. Case Report. An individual case study of a 42-year-old man with pituitary macroadenoma who underwent surgical treatment through the sphenoid sinus is presented. The patient’s problem before neurosurgical treatment were headaches, which impaired his functioning. The postoperative period was uneventful, but required careful monitoring of the patient for cerebrospinal fluid leakage from the nose, diabetes insipidus and electrolyte disturbances. Discussion. The case we analyzed required intensified multi-directional observation due to the risk of complications. After surgery, the patient was relatively quickly independent in everyday activities. Additionally, he required further support and education from the nursing team. Conclusions. Endoscopic procedure through the nose and sphenoid sinus does not externally mutilate the patient, the postoperative wound is moved deep into the nose. The patient remains physically fit, quickly becomes independent in everyday activities, and requires little assistance from the nurse. Furthermore professional nursing observation of the patient after transsphenoidal endoscopic surgery allows detecting disturbing symptoms, enabling their early recognition and effective treatment.

The esophagus is a muscular membranous organ that participates in the swallowing process by passing solid and liquid substrates from the pharynx into the stomach. The embryonic endoderm, mesoderm, and neural crest cells participate in the development of the esophagus. The pathology of the esophagus is very varied and surgical correction techniques require numerous improvements and refinements. The most common condition is Barret's esophagus due to gastroesophageal reflux, but strictures can also occur either from neoplastic causes or from chemical burns. Studying the anatomy and physiology of the esophagus is essential for both internal medicine and surgical approaches. The treatment of esophageal strictures in recent times is done with esophageal stents. These are made of a variety of materials including metal, polymer, or biodegradable. Clinical results are very good but complications are quite common. The first attempt at stenting was made in the mid-19th century using an ivory tube. In the case of ingestion of caustic substances dilation and stenting have very good results. Immediate and late complications are multiple and can range from pain to failure of the stent to expand completely. [ABSTRACT FROM AUTHOR]

Background and Objectives: The risk of bleeding after endoscopic procedures in patients with liver cirrhosis remains unclear because of secondary blood coagulation disorders. In this study, we used various indices to evaluate the risk of bleeding in patients with cirrhosis. Materials and Methods: Patients with liver cirrhosis aged ≥18 years who underwent endoscopic interventions at Kyung Hee University Hospital at Gangdong between February 2007 and September 2021 were included. Clinical information, including demographic data, laboratory results, the presence of cirrhosis complications, and the degree of fibrosis, was checked and evaluated based on medical records. Results: A total of 101 patients with cirrhosis were analyzed. A total of 16 of the 101 patients (15.8%) experienced bleeding after the endoscopic procedure. One patient (0.99%) presented with spurting, while the others presented with mild oozing. All patients underwent hemostatic procedures using hemoclips. The presence of a varix significantly increased post-endoscopic bleeding (p = 0.03). Patients with FIB > 3.25 showed a statistically significant bleeding tendency (p = 0.00). Conclusions: There was no significant difference in bleeding risk according to the platelet count, prothrombin time, Child–Pugh score, and model for end-stage liver disease (MELD). Considering the degree of liver fibrosis and the invasiveness of the planned procedure, most endoscopic procedures can be performed safely but should be further evaluated in a cohort with a larger sample size.

Objectives  This article evaluates the completeness and accuracy of YouTube videos related to endoscopic transsphenoidal surgery (ETS) as a source for patient information. Design  YouTube was searched using relevant terms pertaining to ETS. Videos were evaluated independently by two physician reviewers experienced in ETS. Video demographics including uploader source along with validity scores based on predetermined checklists were captured. Setting  Internet. Participants  Not applicable. Main Outcome Measures  A novel ETS scoring checklist, the modified DISCERN criteria, and Journal of the American Medical Association (JAMA) benchmark score were used to measure completeness and accuracy of videos. video power index (VPI) was calculated to reflect popularity. Intraclass correlation coefficient was calculated for rater agreement. Results  Seventy-nine videos were included in final scoring and analysis. The ETS score, DISCERN, JAMA, and mean VPI across all included videos were 5.0 ± 2.7, 2.4 ± 0.83, 2.19 ± 0.62, and 8.92 ± 18.1, respectively. Based on the ETS score checklist, 31 (39%) of the videos were rated as poor, 30 (38%) were moderately useful, 17 (22%) were useful, and 1 (1%) was exceptional. There was a significant positive correlation between the ETS, DISCERN, and JAMA scores (p  < 0.001), but no correlation with VPI and the validity scores. There were no significant differences comparing validity scores based on the uploader source. Conclusion  YouTube videos related to ETS have limited usefulness and poor overall validity for patient information. Clinicians should direct patients to other validated sources of information and aim to improve the comprehensiveness of ETS-related videos. [ABSTRACT FROM AUTHOR]

Background: Over the last decades, the use of gastrointestinal (GI) endoscopic procedures has been increased in children worldwide, allowing the early diagnosis and therapeutic intervention in multiple GI diseases. Aims and Methods: In order to evaluate the appropriateness and the diagnostic yield of initial GI endoscopic techniques in children in a Portuguese tertiary hospital, we performed a retrospective cohort study during a 12-month period. Results:A total of 308 procedures were performed in 276 patients; the median age was 11 years and 50.4% were males. Esophago-gastro-duodenoscopy (EGD) corresponded to 81.8% of the procedures and ileo-colonoscopy (IC) to the remaining; 11.6% of the patients underwent both EGD and IC. Overall, 51.3% of the exams showed abnormal macroscopic findings, and 69.6% showed histopathological signs of disease, with IC showing significantly more positive results than EGD (p < 0.05). Considering the different indications independently, abnormal serology for celiac disease, suspected ingestion of foreign bodies, suspected inflammatory bowel disease, and food impaction were frequent in our population; and in the majority of the cases, the suspected diagnosis was confirmed: celiac disease, ingestion of foreign bodies, inflammatory bowel disease, and eosinophilic esophagitis, respectively. On the other hand, despite the high frequency of epigastric pain in this population, only nearly one-third of the patients showed abnormal histological findings. The final diagnosis was established in 63% of the patients, and 39.1% initiated the new treatment. Discussion:Our results emphasize the importance of endoscopic procedures, especially IC, in the diagnosis of GI diseases in pediatric patients, as well as the careful choice of the endoscopic techniques in those with less specific symptoms, as chronic abdominal pain. In this particular situation, given the proportion of cases that may be due to functional disease, good characterization of the clinical context is needed, and endoscopy should be reserved for a second-line approach. Conclusion: It is important to monitor and examine the endoscopic techniques as an index of quality criteria for clinical practice.

Abstract It is recommended that a sharp‐pointed object, such as a dental crown, in the proximal duodenum be retrieved endoscopically if this can be accomplished safely.

Background: Sedation has a beneficial impact on patient’s tolerance to the endoscopic procedure. Conscious sedation is the anesthetic techniques of choice for endoscopic procedure. Conscious sedation for endoscopic procedure could be with one drug or a combination of drugs. There have been broad variations in sedation procedure between different countries, and even between different units within the same country. All drugs which depress the central nervous system have the ability to produce respiratory or cardiovascular complications. Endoscopy has a recorded mortality of 1 in 2000 and a morbidity rate of 1 in 200. These sedation techniques have their effects on patients. The main goal of this study is to describe the effects of conscious sedation on patients' outcome for endoscopic procedure. Methods: The design for this study was a review of literature in the medical databases of PubMed, Scopus, Embase, Cochrane and hand search journals from conferences in English. All studies that evaluated the use of CS for endoscopic procedure were included. Results: The results showed that the pain level of the patient (visual analogue scale) was substantially positive when conscious sedation was used. Conscious sedation, however is a lightly sedated patient who is conscious, amnesic, co-operative on demand and free from fear and anxiety. It is often used during endoscopic procedures to minimize discomfort and relax the patients. The intraoperative hypotension has also been extreme in some medications relative to others. Conclusion: The study revealed that CS is reliable and well tolerated anesthetic technique for endoscopic procedures, and is a better option for elective endoscopic procedures CS benefits for endoscopisit and patient outcome is superior to GA such as; short recovery times, less analgesia requirement, comfortable for patient which in turn, leads to faster induction, faster endoscopy, faster discharge, and faster turnaround time. Patients are usually willing to go home after a couple of hours. Rapid recovery is a benefit not only for patients, but also for hospital and day surgery departments. This increases the overall performance of the endoscopy unit.

Objective: To evaluate the safety and efficacy of endoscopic procedures for ureteroenteric anastomotic strictures (UESs) after radical cystectomy and urinary diversion.Methods: We performed a meta-analysis of relevant articles through March 2020 using PubMed, Embase, and Cochrane Central Register to assess the efficacy of endoscopic procedures in UES according to the PRISMA and PICOS criteria. The main endpoints were success rate and complications, and we also compared the efficacy of different methods and stricture length and side in UES. Cochrane Collaboration's Revman version 5.3 and Stata version 15.1 software were used for statistical analysis.Results: A total of 18 retrospective studies with 697 patients were included. The median follow-up ranges from 12 to 62.5 months. Patients treated with endoscopic procedures had an overall success rate of 46%. The pooled rate of Clavien–Dindo ≥ 3 complications was 3.8% among included studies. Laser vaporization and stent insertion (48 and 47%) had a relatively high success rate than balloon dilatation (35%). In subgroup analysis, the success rate of endoscopic procedures for ≤ 1-cm strictures was significantly higher than that for >1-cm ones [odds ratio (OR), 8.65; 95% confidence interval (CI), 3.53–21.21; P < 0.00001]. In addition, the success rate in cases with strictures of the right side was relatively higher than that in cases with strictures of the left side (OR, 1.72; 95% CI, 1.05–2.81; P = 0.03).Conclusion: Our pooled studies showed that endoscopic operation is feasible and associated with a moderate success rate along with a relatively low incidence of perioperative complications in the treatment of UES, especially with length ≤ 1 cm and right side. Although there is still no consensus on endoscopic technique for UES regarding balloon dilatation, stent insertion, and laser vaporization, we believe that endoscopic management is a safety and available approach for UES with close follow-up.

Background: Although endoscopic calcaneoplasty and retrocalcaneal debridement have been extensively applied to treat Haglund syndrome, evidence of the value of the endoscopic procedure remains to be fully established. Purpose/Hypothesis: The purpose of this study was to compare the postoperative outcomes and the amount of osteotomy between open and endoscopic surgery for the treatment of Haglund syndrome. It was hypothesized that endoscopic calcaneoplasty would lead to higher patient satisfaction and lower complication rates compared with open surgical techniques. Study Design: Cohort study; Level of evidence, 3. Methods: The following postoperative outcomes were compared between the open surgery group (n ¼ 20) and the endoscopic surgery group (n ¼ 27): visual analog scale for pain, American Orthopaedic Foot & Ankle Society ankle-hindfoot scale, Foot Function Index, Tegner score, Ankle Activity Score, and 36-Item Short Form Health Survey; postoperative complications; and duration of surgery. To determine the extent of resection, the authors compared the calcaneal height ratio, calcaneal resection ratio, calcaneal resection angle, pitch line, and Haglund deformity height between groups. The learning curve for endoscopic calcaneoplasty was also calculated. Results: There were no significant differences between the open and endoscopic groups on any outcome score. Two patients in the open group reported temporary paresthesia around the incisional site, indicating sural nerve injuries; no complication was reported in the endoscopy group. None of the parameters for extent of resection were statistically significant between the groups. The duration of surgery was 44.90 ± 10.52 and 65.39 ± 11.12 minutes in the open and endoscopy groups, respectively (P ¼ .001). Regarding the learning curve for endoscopic calcaneoplasty (6 surgeons; 27 follow-up patients; 9 patients lost to follow-up), the duration of surgery reached a steady point of 55.68 ± 4.19 minutes after the fourth operation. Conclusion: The results of this study indicated that the endoscopy procedure was as effective as the open procedure. The endoscopic procedure required significantly more time than the open procedure, and the duration of the endoscopic procedure was shortened only after the fourth operation, suggesting that it requires high technical skills and familiarity with the anatomic relationships.

Background: Delayed acute subdural hematoma (DASDH) is defined as late onset ASDH with the absence of any abnormal radiological and clinical findings at initial examination. Moreover, this entity is very rare in traumatic brain injury and its mechanism is still unclear. Recently, endoscopic surgery for ASDH has also been performed. In this case, we describe some considerations of the mechanism of DASDH and review previous literature and usefulness of endoscopic surgical procedure for ASDH. Case Description: A 73-year-old man fell at night, and visited a former medical institution by himself. No abnormal neurological finding was detected. Head computed tomography (CT) detected no abnormal finding. He was diagnosed minor head injury and was hospitalized at midnight and discharged after brain magnetic resonance image (MRI) next day. Brain MRI also detected no abnormal findings. Three days later, he visited our hospital himself, because of the severe headache. Neurologically, he had a mild consciousness disturbance and head CT revealed left ASDH. We performed endoscopic evacuation of hematoma under local anesthesia. Then, the clot was evacuated under the endoscopic procedure through dilated burr hole and pulsatile bleeding from the cortical artery was observed, which was considered to be the source of the ASDH. The patient's consciousness disturbance was improved immediately after surgery and he discharged without neurological deficit. Conclusion: We revealed the source of bleeding of DASDH under endoscopic procedure and described hypothesis and speculation of its cause in our case. DASDH is rare entity, so we need further experiences and more considerations. [ABSTRACT FROM AUTHOR]

The rectal tonsil is a rare polypoid lesion exclusively found in the rectum and is considered a reactive proliferation of the lymphoid tissue. Although this lesion is benign, we recommend that it should be differentiated from carcinoid or polypoid type of mucosa-associated lymphoid tissue lymphomas, based on gross findings. In this case report, we describe a case of rectal lesions with a unique appearance in a 41-year-old man. Colonoscopy revealed two 5-mm-sized nodules located opposite from each other on the left and right sides of the lower rectum. Endoscopic mucosal resection was conducted. Histopathologically, both lesions were mainly located in the submucosa and consisted of prominent lymphoid follicles with germinal centers of various sizes. No immunoreactivity of Bcl-2 was seen in the germinal centers. Immunohistochemical staining for kappa and lambda light chains revealed a polyclonal pattern. Therefore, these lesions were diagnosed as rectal tonsils.

The usefulness of endoscopic procedures for chronic subdural hematoma (CSDH) has been described, but the indications in patients of very advanced age have not been analyzed. The aim of this study was to evaluate the feasibility, safety, and usefulness of introduction of an endoscopic procedure for such patients. We retrospectively analyzed the data of 540 CSDHs treated by burr-hole surgery with endoscopic examination. The safety of the endoscopic procedure was assessed according to postoperative complications, morbidity, and mortality. The outcome was evaluated by statistical comparison among 4 different age-groups, and the recurrence rate and risk factors for recurrence was investigated in patients of very advanced age. Postoperative complications occurred in 7 cases (1.5%). The 6-month morbidity and mortality were 13.5% and 4.5%. No complications, morbidity, or mortality associated with the additional endoscopic procedure occurred even in patients of very advanced age. The endoscopic features of trabecular structures and residual septa separating the cavity were also risk factors for recurrence in patients of very advanced age. Releasing of the septa showed the possibility of decreasing the risk of recurrence to 6.6% in patients aged ≥85 years as well as in younger patients. There were some inevitable problems such as prolongation of the surgical time and inadequate endoscopic surgical skill. An endoscopic procedure for CSDH can be safely indicated and useful even in patients aged ≥85 years. However, clinicians should carefully select the patients based on clinical information associated with risk factors for recurrence. [ABSTRACT FROM AUTHOR]

The radial force of esophageal stents may not completely change during extraction and therefore, the procedure of stent removal may cause tissue damage. The present study reports the manufacture of 2 novel detachable stents, which were designed to reduce tissue damage through their capacity to be taken or fall apart prior to removal and evaluated the supporting properties of these stents and the extent of local mucosal injury during their removal. The stents were manufactured by braiding, heat-setting, coating and connecting. The properties of the stents were evaluated by determining the following parameters: Expansion point, softening point, stent flexibility, radial compression ratio and radial force. A total of 18 rabbits with induced esophageal stricture were randomly assigned to 3 groups as follows: Detachable stent (DS) group, biodegradable stent (BS) group and control group. The stricture rate, complications, survival, degradation and stent removal were observed over 8 weeks. The stents of the DS and BS groups provided a similar supporting effect. The stricture rate, incidence of complications and survival were also similar between the 2 groups, while significant differences were noted between the DS and control groups and between the BS and control groups. In the BS group, the stents were degraded and moved to the stomach within 7 weeks (2 in 6 weeks and 3 in 7 weeks). The debris was extracted using biopsy forceps. In the DS group, all stents were easy to remove and 2 cases exhibited minor hemorrhage. In conclusion, the 2 types of novel detachable stent provided an equally efficient supporting effect in vitro and in vivo and may reduce the incidence of secondary injury during stent removal.

Background and Objectives: Two-dimensional (2D) images lack depth information and thus provide probabilistic recognition that do not completely match the actual three-dimensional (3D) information. Here, we investigated the operability of 3D endoscopes.Methods: A 3D operation model was developed by passing 20 silk threads through upper and lower plates at 2-mm intervals in front and back rows separated by 1 mm. We evaluated accuracy and time of operating an electrosurgical knife. A successful operation was defined as pulling only a front-row thread; an unsuccessful operation was defined as pulling no thread (miss) or simultaneously pulling front- and back-row threads. Endoscopists (four experts, six trainees) repeated the operation under 2D and 3D conditions until individually accumulating 10 successful attempts under each condition.Results: Operation accuracy was significantly higher for 3D compared with 2D in all endoscopists (88.5% vs. 61.3%; p < 0.01) and in both experience groups (trainees: 84.5% vs. 61.2%; experts: 95.2% vs. 61.5%; both p < 0.01). Operation time was significantly shorter for 3D compared with 2D in all endoscopists (12.5 ± 4.1 s vs. 14.8 ± 4.7 s; p < 0.01) and in both experience groups (trainees: 12.8 ± 4.2 s vs. 15.2 ± 4.9 s; experts: 12.1 ± 4.0 s vs. 14.3 ± 4.3 s; both p < 0.01).Discussion: Compared with 2D endoscopy, 3D endoscopy significantly improved operation accuracy and shortened operation time, suggesting that 3D endoscopy enables accurate operation by depth information, aiding spatial recognition.

The surgical resection of large supracerebellar hemangioblastomas (SHBs) is exceptionally challenging due to their vascularity and deep anatomic location and is associated with a high risk of postoperative complications and mortality. Access to the posterior incisural space can be achieved by either an infratentorial supracerebellar approach or occipital transtentorial approach (OTA). However, the optimal surgical strategy has not yet been established. Here, we report 2 cases of large SHBs that were successfully and safely resected via a unilateral OTA with multimodal assistance. Two patients presented to our hospital with ataxia due to large, solid SHBs. After preoperative embolization, gross total resection of the SHBs was achieved via an OTA. Furthermore, endoscopic assistance was used to resect the remnant portion of the tumor in the second patient. Both patients experienced transient ataxia but were discharged from the hospital without serious complications. The combination of an OTA with preoperative embolization and endoscopic assistance may reduce the intraoperative risk and contribute to improved outcome in patients with such clinically challenging tumors.

Introduction: Hepatic hematoma is a rare but possible complication of ERCP. We describe the case of a 75-year old man with a large, 8 × 12 cm, sub-capsular and intra-parenchymal hematoma post ERCP, affecting the right liver segments and treated conservatively.Areas Covered: A review of literature has been performed, highlighting two possible mechanisms: hematoma may occur as the result of accidental laceration of a small intrahepatic vessel by the guidewire, whereas the other hypothesis posits that the hepatic damage is secondary to traction on the biliary system exerted by the balloon. We speculate that in case of anomalies of the biliary tree, the incidence of this complication is higher than expected.Expert Commentary: In case of hepatic hematoma post ERCP, a conservative approach should always be considered before proceeding to interventional radiologic procedures or to surgical therapy.

Diaphragmatic hernia (DH) is a defect, which can be congenital or can develop later in life. Moreover, chromosomal and genetic abnormalities, environmental exposures, and nutritional deficiencies may be related to the development of congenital DH. In contrast, the risk factors of acquired DH include traumas, such as blunt injuries due to traffic accidents and surgical procedures. We report the case of a 71-year-old man admitted to our gastroenterology department for the treatment of esophageal varices. Four days after the endoscopic treatment, the patient vomited severely and reported severe right upper abdominal pain. He was diagnosed with DH, and surgical fixation was performed. The diaphragmatic injury lesion was located on the estimated needle track of percutaneous radiofrequency ablation, which was performed through the thoracic diaphragm with artificial pleural effusion for hepatocellular carcinoma.

Parotid gland swelling, or parotitis, typically associated with infectious causes, can uncommonly result from non-infectious factors such as mechanical trauma following endoscopic procedures. We present a case of a 46-year-old female with liver cirrhosis who developed right parotid swelling shortly after undergoing endoscopy for evaluation of gastrointestinal symptoms. The patient's clinical course, imaging findings, and successful resolution with conservative measures are detailed. The etiology of post-endoscopy parotid swelling is multifactorial, involving potential mechanisms such as mechanical trauma, salivary gland dysfunction, infection, ductal obstruction, or allergic reactions to medications. Diagnosing this rare complication requires a comprehensive clinical evaluation, including a detailed history, symptom assessment, and imaging studies such as ultrasound. Management involves a combination of symptomatic relief, identification, and treatment of the underlying cause, emphasizing the importance of early recognition to prevent complications. In our case, warm compression provided pain relief, and the swelling subsided without the need for medical or surgical intervention. Regular follow-up evaluations and imaging studies are crucial to assess treatment response and ensure the resolution of the swelling. This case contributes to the limited literature on post-endoscopy parotid swelling, emphasizing the significance of recognizing and managing this rare complication promptly. Healthcare professionals should be vigilant, and further research is encouraged to better understand its pathophysiology and optimize management strategies in order to improve patient outcomes., Competing Interests: The authors have declared that no competing interests exist., (Copyright © 2024, Taori et al.)

Endoscopic retrograde cholangiopancreatography (ERCP) is an endoscopic procedure for indications of pancreatobiliary diseases. Hepatic hematoma is a very rare complication of this procedure. In this case report, we aimed to present subcapsular hepatic hematoma complication and review current literature. A 72-year-old woman was admitted with jaundice to our outpatient clinic. Her lab results were as follows: ALT 700 U/L (15-35), AST: 472 U/L (15-35), ALP: 355 U/L (40-120), T. Bilirubin: 5.5 mg/dl (0.3-1.2), D. Bil: 3.15 mg/dl (0-0.2), GGT: 212 U/L (0-38). Magnetic resonance cholangiopancreatography (MRCP) and contrast-enhanced magnetic resonance imaging (MRI) revealed a lesion involving the proximal common bile duct (CBD), possibly extending into both major hepatic bile ducts and causing narrowing of the lumen and contrast enhancement (Klatskin tumor?). Intrahepatic biliary tracts were dilated in both lobes, especially on the left. Due to the involvement of CBD, biliary plastic stenting was performed for malignant biliary obstruction (bismuth type 2) with ERCP. On the second day after ERCP, the patient complained of abdominal pain radiating to the back with no defence and rebound tenderness. Lab results were as follows; ALT: 342 U/L (15-35), AST: 329 U/L (15-35), ALP: 306 U/L (40-120), T. Bilirubin:10.2 mg/dl (0.3-1.2), D. Bil:6, 16 mg/dl (0-0,2), GGT:165 U/L (0-38). Computed tomography showed 45 mm of subcapsular hepatic hematoma with air and liquid on the surface of the right lobe of the liver. The patient was conservatively treated and followed up with antibiotherapy in surgery intensive care unit. She was not suitable for surgery and percutaneous drainage or vascular embolization. In conclusion, subcapsular hepatic hematoma is a rare complication of ERCP. Moreover, its mortality rate is low and it may occur in certain conditions. If abdominal pain, fever, anemia and hypotension develop in the patient, this complication should be considered after ERCP. It should be included in informed consent for the ones who will perform ERCP in endoscopy units. [ABSTRACT FROM AUTHOR]
