Modified Lamaze Breathing Reduces Abdominal Pain in Patients during Colonoscopy. COMPUTATIONAL AND MATHEMATICAL METHODS IN MEDICINE 2022; 2022:1557861. [PMID: 35928975 PMCID: PMC9345707 DOI: 10.1155/2022/1557861] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 05/25/2022] [Revised: 07/12/2022] [Accepted: 07/15/2022] [Indexed: 11/17/2022]
Abstract
Objective. To study the effects of modified Lamaze breathing on abdominal pain experienced during colonoscopy. Methods. Eighty-five patients who underwent common colonoscopy at our hospital between March 2021 and May 2021 were selected and randomly divided into the Lamaze group (
) and a control group (
). Their basic clinical information was collected, and the bowel cleanliness, the time for the endoscope to reach the ileocecal junction, and the degree of abdominal pain of the two groups were compared. Results. No significant difference was observed in age, gender, bowel cleanliness, and time of endoscope to reach the ileocecal junction between the two groups. However, the degree of abdominal pain (anal region, descending sigmoid colon junction, splenic flexure, and hepatic flexure) was significantly lower in the Lamaze group compared with the control group. Conclusion. Modified Lamaze breathing demonstrated promising effectiveness in reducing abdominal pain during colonoscopy and improving the quality of the examination.

Abstract
BACKGROUND Aspiration pneumonia after endoscopic submucosal dissection (ESD) is rare, but can be fatal. We aimed to investigate risk factors and develop a simple risk scoring system for aspiration pneumonia. METHODS We retrospectively reviewed medical records of 7833 patients who underwent gastric ESD for gastric neoplasm under anesthesiologist-directed sedation. Candidate risk factors were screened and assessed for significance using a least absolute shrinkage and selection operator (LASSO)-based method. Top significant factors were incorporated into a multivariable logistic regression model, whose prediction performance was compared with those of other machine learning models. The final risk scoring system was created based on the estimated odds ratios of the logistic regression model. RESULTS The incidence of aspiration pneumonia was 1.5%. The logistic regression model showed comparable performance to the best predictive model, extreme gradient boost (area under receiver operating characteristic curve [AUROC], 0.731 vs 0.740). The estimated odds ratios were subsequently used for the development of the clinical scoring system. The final scoring system exhibited an AUROC of 0.730 in the test dataset with risk factors: age (≥70 years, 4 points), male sex (8 points), body mass index (≥27 kg/m2, 4 points), procedure time (≥80 minutes, 5 points), lesion in the lower third of the stomach (5 points), tumor size (≥10 mm, 3 points), recovery time (≥35 minutes, 4 points), and desaturation during ESD (9 points). For patients with total scores ranging between 0 and 33 points, aspiration pneumonia probabilities spanned between 0.1% and 17.9%. External validation using an additional cohort of 827 patients yielded AUROCs of 0.698 for the logistic regression model and 0.680 for the scoring system. CONCLUSIONS Our simple risk scoring system has 8 predictors incorporating patient-, procedure-, and sedation-related factors. This system may help clinicians to stratify patients at risk of aspiration pneumonia after ESD.

Abstract
BACKGROUND AND AIMS Few studies have directly compared the efficacy of sedated- and un-sedated endoscopic variceal ligation (EVL) for acute variceal bleeding. We aimed to determine whether sedation during EVL in patients with variceal bleeding is safe and effective. METHODS We analyzed data from patients who underwent EVL for acute variceal bleeding according to sedation in six hospitals of Hallym University Medical Center. The primary endpoint was treatment failure, defined as a failure to control bleeding, death during EVL, or rebleeding within 5 days. Secondary endpoints included the procedure time, adverse events, and 30-day mortality. RESULTS Of 1,300 patients who were included, only 430 (33.1%) received sedation during EVL. Propofol alone was used for sedation in 85% of sedated-EVLs. The mean procedure time in the sedation group was shorter than that of the non-sedation group (12.4 ± 9.5 min versus 13.8 ± 9.4 min, P = 0.010). The proportion of treatment failure did not differ between the groups (7.4% versus 9.1%, P = 0.374). In the multivariable analysis, an AIMS65 score ≥2 and blood transfusion within 72 hours were associated with treatment failure of EVL; however, the use of sedation was not (odds ratio [95% confidence interval (CI)] = 0.96 [0.60-1.51]). Adverse events during EVL and hepatic encephalopathy did not differ between the two groups. Sedation also did not affect the 30-day mortality (hazard ratio [95% CI] = 0.99 [0.66-1.47]). CONCLUSION Sedation reduced the procedure time of EVL. Sedation is safe to use during EVL for variceal bleeding in patients with cirrhosis.

Abstract
BACKGROUND Endoscopic submucosal dissection (ESD) has a favorable outcome, compared to esophagectomy, for early esophageal neoplasia. Recent studies used general anesthesia for esophageal ESD to minimize complications due to insufficient sedation and patient movement. We aimed to evaluate the safety of general anesthesia in comparison with conscious sedation provided by anesthesiologists for esophageal ESD. METHODS We retrospectively reviewed the electronic medical records of 158 patients who underwent esophageal ESD under general anesthesia or conscious sedation provided by anesthesiologists. We evaluated the incidence of procedure-related complications, including perforation, post-ESD bleeding, cardiopulmonary adverse events (arrhythmia, hypotension, and hypoxemia), procedure failure, stricture, and new lung consolidation after ESD. Cases of frank perforation, post-ESD bleeding requiring a vigorous diagnostic approach, and cardiopulmonary adverse events were regarded as acute complications of ESD. RESULTS Acute complications occurred only in the conscious sedation group (8/83 [9.6%] vs. 0/75 [0.0%]; p value = 0.007). The numbers of patients with frank perforation, post-ESD bleeding, and cardiopulmonary adverse events were four, one, and three, respectively. Moreover, new lung consolidation after ESD developed only in the conscious sedation group (7/83 [8.4%] vs. 0/75 [0.0%]; p value = 0.014). ESD failed in four patients in the conscious sedation group. The incidences of stricture that required stent insertion and hospital stay after ESD were comparable between the two groups. CONCLUSION General anesthesia is associated with a lower incidence of acute procedure-related complications in esophageal ESD compared to conscious sedation provided by anesthesiologists. Therefore, we recommend general anesthesia as a safer option for esophageal ESD.

Risk factors for perforation of gastric endoscopic submucosal dissection: a systematic review and meta-analysis. Eur J Gastroenterol Hepatol 2019; 31:1481-1488. [PMID: 31688250 DOI: 10.1097/meg.0000000000001543] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 02/07/2023]
Abstract
The aim of this systematic review and meta-analysis was to identify significant risk factors for perforation in gastric endoscopic submucosal dissection. Studies published in the English language were searched for in Embase, WEB OF SCIENCE, Medline (PubMed and Ovid) and the Cochrane Central Register of Controlled Trials and Database of Systematic Reviews. Inclusion criteria and exclusion criteria were defined in advance in this work. Probable risk factors in a total of eighteen studies were evaluated, and the results are represented in the case of dichotomous variables as an odds ratio (with 95% confidence interval). Analysing the risk factors, the odds ratios were 1.98 (95% confidence interval: 1.02-3.85) for liver disease; 3.62 (95% confidence interval: 2.83-4.65) for vertical localization (the upper portion of the stomach); 1.42 (95% confidence interval: 1.03-1.96) for resected size (>20 mm); 3.05 (95% confidence interval: 1.80-5.17) for depth of invasion (submucosal); 4.12 (95% confidence interval: 1.63-10.39) for operation time (>2 hours); 1.59 (95% confidence interval: 1.25-2.01) for gross type of lesion (depressed or flat); and 3.88 (95% confidence interval: 2.69-5.60) for piecemeal resection. Liver disease, vertical localization (the upper portion of the stomach), resected size (>20 mm), depth of invasion (submucosal), operation time (>2 hours), gross type of lesion (flat or depressed), and piecemeal resection were verified to be risk factors for perforation of gastric endoscopic submucosal dissection.

Abstract
Background: Endoscopic resection (ER) and gastrectomy have been both accepted as curative treatments for early gastric cancer. We intended to compare ER with gastrectomy treatments on safety of patients, disease-free survival and overall survival for early gastric cancer through this systematic review. Methods: A literature search was performed in Pubmed, Embase, and Cochrane Library databases. Studies that have compared ER with gastrectomy for early gastric cancer were included in this meta-analysis. We searched for clinical studies published before March 2019. Stata 12.0 software was used for systematic analysis. Results: Nine studies were included in this systematic review, ER treatment was associated with a shorter length of stay (WMD = -8.53, 95% CI -11.56 to -5.49), fewer postoperative complications (OR = 0.47, 95% CI 0.34-0.65). ER can be performed safely with shorter hospital stay and fewer postoperative complications than gastrectomy. Recurrence rate was higher for ER than for gastrectomy treatment (HR = 3.56, 95% CI 1.86-6.84), mainly because metachronous gastric cancers developed only in the ER treatment. However, most of the metachronous gastric cancers could be curatively treated with ER again, and it didn't affect overall survival of patients with early gastric cancer. There was no difference in overall survival rate between ER and gastrectomy (HR = 0.84, 95% CI 0.63-1.13). Conclusions: ER and gastrectomy are both acceptable for curative treatment of early gastric cancer. However, due to the comparable overall survival and lower postoperative complications and shorter length of stay, ER is better than gastrectomy for early gastric cancer, who met the indication for ER treatment.

Abstract
With the rapid development of diagnostic and therapeutic procedures performed outside the operating room (OR), the need for appropriate sedation care has emerged in importance to ensure the safety and comfort of patients and clinicians. The preparation and administration of sedatives and sedation care outside the OR require careful attention, proper monitoring systems, and clinically useful sedation guidelines. This literature review addresses proper monitoring and selection of sedatives for diagnostic and interventional procedures outside the OR. As the depth of sedation increases, respiratory depression and cardiovascular suppression become serious, necessitating careful surveillance using appropriate monitoring equipment.

Abstract
Background Although pulmonary aspiration complicating operative general anaesthesia has been extensively studied, little is known regarding aspiration during procedural sedation. Methods We performed a comprehensive, systematic review to identify and catalogue published instances of aspiration involving procedural sedation in patients of all ages. We sought to report descriptively the circumstances, nature, and outcomes of these events. Results Of 1249 records identified by our search, we found 35 articles describing one or more occurrences of pulmonary aspiration during procedural sedation. Of the 292 occurrences during gastrointestinal endoscopy, there were eight deaths. Of the 34 unique occurrences for procedures other than endoscopy, there was a single death in a moribund patient, full recovery in 31, and unknown recovery status in two. We found no occurrences of aspiration in non-fasted patients receiving procedures other than endoscopy. Conclusions This first systematic review of pulmonary aspiration during procedural sedation identified few occurrences outside of gastrointestinal endoscopy, with full recovery typical. Although diligent caution remains warranted, our data indicate that aspiration during procedural sedation appears rare, idiosyncratic, and typically benign.

Abstract
AIM To investigate that polysomnographic monitoring can accurately evaluate respiratory disturbance incidence during sedation for gastrointestinal endoscopy compare to pulse oximetry alone.
METHODS This prospective observational study included 10 elderly patients with early gastric cancer undergoing endoscopic submucosal dissection (ESD) under propofol sedation. Apart from routine cardiorespiratory monitoring, polysomnography measurements were acquired. The primary hypothesis was tested by comparing the apnea hypopnea index (AHI), defined as the number of apnea and hypopnea instances per hour during sedation, with and without hypoxemia; hypoxemia was defined as the reduction in oxygen saturation by ≥ 3% from baseline.
RESULTS Polysomnography (PSG) detected 207 respiratory disturbances in the 10 patients. PSG yielded a significantly greater AHI (10.44 ± 5.68/h) compared with pulse oximetry (1.54 ± 1.81/h, P < 0.001), thus supporting our hypothesis. Obstructive AHI (9.26 ± 5.44/h) was significantly greater than central AHI (1.19 ± 0.90/h, P < 0.001). Compared with pulse oximetry, PSG detected the 25 instances of respiratory disturbances with hypoxemia 107.4 s earlier on average.
CONCLUSION Compared with pulse oximetry, PSG can better detect respiratory irregularities and thus provide superior AHI values, leading to avoidance of fatal respiratory complications during ESD under propofol-induced sedation.

Abstract
BACKGROUND The comparative efficacy of various anti-ulcer medications after gastric endoscopic submucosal dissection (ESD) has not been fully evaluated. Recently, vonoprazan, a novel potassium-competitive acid blocker, has also been used in ulcer treatment after ESD. METHODS We searched for all relevant randomized controlled trials examining the efficacy of anti-ulcer medications after gastric ESD, published through October 2017. Healing of iatrogenic ulcers was investigated at 4-8 weeks after ESD. A network meta-analysis was performed to calculate the network estimates. RESULTS Twenty-one studies with 2005 patients were included. Concerning the comparative efficacy for ulcer healing at 4 weeks after ESD, no network inconsistency was identified (Cochran's Q-test, df = 10, P = 0.13; I2 = 34%). A combination therapy of proton-pump inhibitor (PPI) and muco-protective agent was superior to PPI alone [risk ratio (RR) (95% confidence interval, CI) 1.69 (1.20-2.39)]. The combination therapy of PPI and muco-protective agents tended to be superior to vonoprazan [RR (95% CI) 1.98 (0.99-3.94)]. There was no difference of ulcer healing effect between PPI and vonoprazan [RR (95% CI) PPI vs. vonoprazan, 1.17 (0.64-2.12)]. Concerning the ulcer healing rate at 8 weeks after ESD, however, vonoprazan was superior to PPI [RR (95% CI) 1.27 (1.03-1.56)]. Additionally, vonoprazan tended to be superior to the combination therapy of PPI and muco-protective agent [RR (95% CI) 1.20 (0.96-1.51)]. CONCLUSIONS A combination therapy of PPI and muco-protective agent was superior to PPI alone for ulcer healing at 4 weeks after ESD. In the ulcer healing effect at 8 weeks after ESD, vonoprazan was superior to PPI.

Abstract
AIM To compare endoscopic submucosal dissection (ESD) outcomes between Eastern and Western countries. METHODS A systematic review and meta-analysis was performed using PubMed, MEDLINE, Web of Science, CINAHL and EBM reviews to identify studies published between 1990 and February 2016. The primary outcome was the efficacy of ESD based on information about either curative resection, en bloc or R0 resection rates. Secondary outcomes were complication rates, local recurrence rates and procedure times. RESULTS Overall, 238 publications including 84318 patients and 89512 gastrointestinal lesions resected using ESD were identified. 90% of the identified studies reporting ESD on 87296 lesions were conducted in Eastern countries and 10% of the identified studies reporting ESD outcomes in 2216 lesions were from Western countries. Meta-analyses showed higher pooled percentage of curative, en bloc, and R0 resection in the Eastern studies; 82% (CI: 81%-84%), 95% (CI: 94%-96%) and 89% (CI: 88%-91%) compared to Western studies; 71% (CI: 61%-81%), 85% (CI: 81%-89%) and 74% (CI: 67%-81%) respectively. The percentage of perforation requiring surgery was significantly greater in the Western countries (0.53%; CI: 0.10-1.16) compared to Eastern countries (0.01%; CI: 0%-0.05%). ESD procedure times were longer in Western countries (110 min vs 77 min). CONCLUSION Eastern countries show better ESD outcomes compared to Western countries. Availability of local ESD expertise and regional outcomes should be considered for decision making to treat gastrointestinal lesions with ESD.

Efficacy and safety of etomidate-based sedation compared with propofol-based sedation during ERCP in low-risk patients: a double-blind, randomized, noninferiority trial. Gastrointest Endosc 2018; 87:174-184. [PMID: 28610897 DOI: 10.1016/j.gie.2017.05.050] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/05/2017] [Accepted: 05/25/2017] [Indexed: 12/11/2022]
Abstract
BACKGROUND AND AIMS Etomidate is a short-acting intravenous hypnotic with a safety profile that is superior to alternative drugs such as propofol. However, there is a lack of evidence on the safety of etomidate in ERCP. The objective of this study was to compare efficacy and safety profiles of etomidate and propofol for endoscopic sedation. METHODS This single-center, randomized, double-blind, noninferiority trial included patients with American Society of Anesthesiologists (ASA) physical status I to II who had been scheduled for ERCP. All patients received .05 mg/kg midazolam intravenously as pretreatment before receiving etomidate or propofol. Either etomidate or propofol was then administered according to group allocation. The primary endpoint was an overall respiratory event. A noninferiority margin of 10% was assumed. RESULTS Sixty-three and 64 patients were enrolled in the etomidate and propofol groups, respectively. Respiratory events were identified in 10 patients (15.6%) in the etomidate group and 16 patients (25.4%) on the propofol group, with a rate difference of -9.8% (1-sided 97.5% confidence interval, -∞ to 4.2%). The overall incidence of cardiovascular events tended to be higher in the etomidate group (67.2% vs 50.8%, P = .060). In particular, tachycardia (heart rate > 100 beats/min) was more common in the etomidate group than in the propofol group (64.1% vs 34.9%, P = .001). Transient hypotension tended to be less common in the etomidate group (6.3 vs 15.9%, P = .084). CONCLUSIONS Etomidate-based sedation during ERCP was noninferior to propofol-based sedation in terms of the overall incidence of respiratory events in patients with ASA physical status I to II.

Abstract
BACKGROUND Only a few studies have reported long-term outcomes for endoscopic submucosal dissection (ESD) of early gastric cancer (EGC) in elderly patients. The aim of this study was to evaluate the efficacy of ESD for EGC in elderly patients ≥75 years with respect to both short- and long-term outcomes. METHODS We reviewed the clinical data of elderly patients ≥75 years who had undergone ESD for EGC at Tonan Hospital from January 2003 to May 2010. RESULTS A total of 177 consecutive patients, including 145 with curative resection (CR) and 32 with noncurative resection (non-CR), were examined. Of the 32 patients with non-CR, 15 underwent additional surgery, and lymph node metastases were found in 3 patients. The remaining 17 patients were followed without additional surgery because of advanced age or poor general condition. Procedure-related complications, such as post-ESD bleeding, perforation and pneumonia, were within the acceptable range. The 5-year survival rates of patients with CR, those with additional surgery after non-CR, and those without additional surgery after non-CR were 84.6, 73.3, and 58.8 %, respectively. No deaths were attributable to the original gastric cancer; patients succumbed to other illnesses, including malignancy and respiratory disease. CONCLUSIONS In elderly patients, ESD is an acceptable treatment for EGC in terms of both short- and long-term outcomes. Careful clinical assessment of elderly patients is necessary before ESD. After ESD, medical follow-up is important so that other malignancies and diseases that affect the elderly are not overlooked.

J Gastroenterol Hepatol 2017; 32:756-768. [PMID: 27796052 DOI: 10.1111/jgh.13623] [Citation(s) in RCA: 15] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/18/2016] [Revised: 10/17/2016] [Accepted: 10/18/2016] [Indexed: 02/07/2023]
Abstract
BACKGROUND Although several studies have shown that second-look endoscopy does not affect the incidence of bleeding after gastric endoscopic submucosal dissection (ESD), the potential roles of second-look endoscopy have not been fully evaluated. This study aimed to determine the role of second-look endoscopy after ESD through a systematic review and meta-analysis. METHODS This study conducted a systematic literature search of MEDLINE, EMBASE, and the Cochrane Library through March 2016 using the keywords "second-look," "prophylactic hemostasis," "prophylactic haemostasis," "prevention," "prophylaxis," and "endoscopic submucosal dissection." Studies were included if they evaluated the incidence of post-ESD bleeding according to second-look endoscopy or prophylactic hemostasis during second-look endoscopy. RESULTS Four randomized controlled trials on post-ESD bleeding between second-look endoscopy and no second-look endoscopy and 12 non-randomized studies with a cohort design on post-ESD bleeding were included. On meta-analysis, second-look endoscopy did not affect delayed post-ESD bleeding (odds ratio [95% confidence interval] = 1.27 [0.80-2.00], I2 = 0%). During second-look endoscopy, patients who were considered as high-risk for post-ESD bleeding underwent prophylactic hemostasis. Delayed post-ESD bleeding was more common in patients who were treated with hemostasis during second-look endoscopy compared with those who were not (odds ratio [95% confidence interval] = 3.40 [1.87-6.18], I2 = 62%). In patients who underwent prophylactic hemostasis, the number needed to prolong a hospitalization period to avoid one additional post-ESD bleeding after discharge was 25. CONCLUSION Second-look endoscopy after ESD could not reduce the risk of delayed post-ESD bleeding. Delayed post-ESD bleeding was more common in patients who underwent prophylactic hemostasis than in those who did not.

Abstract
BACKGROUND/AIMS This prospective cohort study aimed to elucidate the incidence and characteristics of pneumonia associated with endoscopic submucosal dissection (ESD) of gastric neoplasms using CT. METHODS We included consecutive 188 patients with gastric neoplasms treated with ESD. All patients underwent CT before ESD and the day after ESD. Pneumonia associated with ESD was defined as lung ground glass opacity or consolidation by CT the day after ESD. RESULTS In 188 patients, 28 patients had diabetes mellitus. Pneumonia was observed by CT in 21 patients (11.2%) after ESD. Of those, 7 patients had diabetes mellitus. By univariate analysis, compared with patients with non-pneumonia complications, risk factors for pneumonia were significantly increased in patients with diabetes mellitus (p = 0.01) and in those who underwent a long procedure time (p = 0.02). By multivariate analysis, pneumonia was significantly increased in patients with diabetes mellitus (OR 4.06, 95% CI 1.35-12.19) and in those who underwent a long procedure time (OR 1.01, 95% CI 1.00-1.02). CONCLUSIONS The incidence of CT-diagnosed pneumonia associated with ESD was relatively high. Furthermore, it was revealed that diabetes mellitus and a long procedure time were risk factors of CT-diagnosed pneumonia.

Abstract
Endoscopic submucosal dissection (ESD) is an advanced therapy for early gastric neoplasm and requires sedation with adequate analgesia. Lidocaine is a short-acting local anesthetic, and intravenous lidocaine has been shown to have analgesic efficacy in surgical settings. The aim of this study was to assess the effects of intravenous lidocaine on analgesic and sedative requirements for ESD and pain after ESD.Sixty-six patients scheduled for ESD randomly received either intravenous lidocaine as a bolus of 1.5 mg/kg before sedation, followed by continuous infusion at a rate of 2 mg/kg/h during sedation (lidocaine group; n = 33) or the same bolus and infusion volumes of normal saline (control group; n = 33). Sedation was achieved with propofol and fentanyl. The primary outcome was fentanyl requirement during ESD. We recorded hemodynamics and any events during ESD and evaluated post-ESD epigastric and throat pain.Fentanyl requirement during ESD reduced by 24% in the lidocaine group compared with the control group (105 ± 28 vs. 138 ± 37 μg, mean ± SD; P < 0.001). The lidocaine group reached sedation faster [40 (20-100) vs. 55 (30-120) s, median (range); P = 0.001], and incidence of patient movement during ESD decreased in the lidocaine group (3% vs. 26%, P = 0.026). Numerical rating scale for epigastric pain was significantly lower at 6 hours after ESD [2 (0-6) vs. 3 (0-8), median (range); P = 0.023] and incidence of throat pain was significantly lower in the lidocaine group (27% vs. 65%, P = 0.003). No adverse events associated with lidocaine were discovered.Administration of intravenous lidocaine reduced fentanyl requirement and decreased patient movement during ESD. Moreover, it alleviated epigastric and throat pain after ESD. Thus, we conclude that the use of intravenous adjuvant lidocaine is a new and safe sedative method during ESD.

Abstract
BACKGROUND Although propofol-based sedation can be used during emergency endoscopy for upper gastrointestinal bleeding (UGIB), there is a potential risk of sedation-related adverse events, especially in patients with variceal bleeding. AIM We compared adverse events related to propofol-based sedation during emergency endoscopy between patients with non-variceal and variceal bleeding. METHODS Clinical records of patients who underwent emergency endoscopy for UGIB under sedation were reviewed. Adverse events, including shock, hypoxia, and paradoxical reaction, were compared between the non-variceal and variceal bleeding groups. RESULTS Of 703 endoscopies, 539 and 164 were performed for non-variceal and variceal bleeding, respectively. Shock was more common in patients with variceal bleeding compared to those with non-variceal bleeding (12.2 vs. 3.5%, P < 0.001). All patients except one recovered from shock after normal saline hydration, and emergency endoscopy could be finished without interruption in most cases. The incidence of hypoxia and paradoxical reaction did not differ based on the source of bleeding (non-variceal bleeding vs. variceal bleeding: hypoxia, 3.5 vs. 1.8%, P = 0.275; paradoxical reaction interfering with the procedure, 4.1 vs. 5.5%, P = 0.442). CONCLUSIONS Although shock was more common in patients with variceal bleeding compared to those with non-variceal bleeding, most cases could be controlled without procedure interruption. Paradoxical reaction, rather than shock or hypoxia, was the most common cause of procedure interruption in patients with variceal bleeding, but the rate did not differ between patients with non-variceal and variceal bleeding.

Abstract
BACKGROUND AND AIM The aim of the present study was to evaluate the efficacy and safety of sedation with a combination of propofol (PF) and dexmedetomidine (DEX) compared with sedation with benzodiazepines in esophageal endoscopic submucosal dissection (ESD). METHODS We retrospectively reviewed clinical data for 40 consecutive patients who had undergone esophageal ESD at the Yokohama City University Hospital between July 2012 and August 2014. Of these patients, 20 were sedated with benzodiazepines (conventional group) and another 20 patients were sedated with a combination of PF and DEX (combination group). Parameters for efficacy and safety of sedation were evaluated by comparisons between the two groups. RESULTS Median procedural times in the combination group were shorter than those in the conventional group (61 min vs. 89 min, P = 0.03), and the percentage of patients who showed restlessness in the combination group was significantly lower than that in the conventional group (25% vs. 65%, P = 0.025). Incidences of hypotension and bradycardia in the combination group were higher than those in the conventional group (60% vs. 15%, P = 0.008, and 60% vs. 15%, P = 0.008, respectively). CONCLUSION This retrospective study suggests that a combination of PF and DEX may provide stable deep sedation with less body movement than benzodiazepines during esophageal ESD.

Abstract
ESD is an established effective treatment modality for premalignant and early-stage malignant lesions of the stomach, esophagus, and colorectum. Compared with EMR, ESD is generally associated with higher rates of en bloc, R0, and curative resections and a lower rate of local recurrence. Oncologic outcomes with ESD compare favorably with competing surgical interventions, and ESD also serves as an excellent T-staging tool to identify noncurative resections that will require further treatment. ESD is technically demanding and has a higher rate of adverse events than most endoscopic procedures including EMR. As such,sufficient training is critical to ensure safe conduct and high-quality resections. A standardized training model for Western endoscopists has not been clearly established,but will be self-directed and include courses, animal model training, and optimally an observership at an expert center.Numerous dedicated ESD devices are now available in the United States from different manufacturers. Although the use of ESD in the United States is increasing, issues related to technical difficulty, limited training opportunities and mentors, risk of adverse events, long procedure duration,and suboptimal reimbursement may limit ESD adoption in the United States to a modest number of academic referral centers for the foreseeable future.

Abstract
BACKGROUND Large multicenter gastric cancer endoscopic submucosal dissection (ESD) studies conducted at major Japanese institutions have reported en bloc resection, en bloc tumor-free margin resection, and curative resection rates of 92.7% to 96.1%, 82.6% to 94.5%, and 73.6% to 85.4%, respectively, with delayed bleeding and perforation rates of 0.6% to 6.0% and 3.6% to 4.7%, respectively. Although ESD is currently an alternative treatment in some countries, particularly in Asia, it remains uncertain whether ESD therapeutic outcomes in Western endoscopy settings can be comparable to those achieved in Japan. OBJECTIVE To evaluate the ESD therapeutic outcomes for differentiated early gastric cancer (EGC) in a Western endoscopy setting. DESIGN/SETTING Consecutive case series performed by an expertly trained Western endoscopist. PATIENTS Fifty-three patients with 54 lesions. INTERVENTIONS ESD for early gastric cancers (T1) satisfying expanded inclusion criteria. MAIN OUTCOME MEASUREMENTS En bloc resection, en bloc tumor-free margin resection, and curative resection rates were 98%, 93%, and 83%, respectively. The delayed bleeding rate was 7%, and the perforation rate was 4%. RESULTS The mean patient age was 67 years, and the mean tumor size was 19.8 mm, with 54% of the lesions located in the lesser curvature. The median procedure time was 61 minutes, with ESD procedures 60 minutes or longer associated with submucosal fibrosis (P < .001) and tumor size 25 mm or larger (P = .03). In every ESD procedure, both circumferential incision and submucosal dissection were performed by using a single knife. Two of the 4 delayed bleeding cases required surgery, and all perforations were successfully managed by using endoscopic clips. LIMITATION Long-term outcome data are currently unavailable. CONCLUSION ESD for differentiated EGC resulted in favorable therapeutic outcomes in a Western endoscopy setting comparable to those achieved at major Japanese institutions.

Abstract
The number of elderly people with superficial gastric neoplasms is increasing, but the clinical outcome of endoscopic submucosal dissection (ESD) for treating elderly people with superficial gastric neoplasms remains unclear. We aimed to compare the efficacy and safety of ESD for patients with early gastric cancer (EGC) and precancerous lesions in elderly (≥75 years of age) and nonelderly (<75 years of age) patients.From October 2005 to December 2014, 83 consecutive patients with EGC and precancerous lesions (86 lesions) who were treated using ESD in our hospital were retrospectively reviewed. There were 44 lesions in 42 elderly patients who were at least 75-years old. The following parameters were compared between the 2 groups: preexisting comorbidities, performance status (PS), lesion inclusion criteria, lesion characteristics, treatment outcomes, surgery time, duration of hospitalization, complications, and intraoperative hemodynamic changes.Elderly patients had significantly higher preexisting comorbidity rates (90.9% vs 59.5%, P = 0.001), expanded lesion criteria rates (43.2% vs 19.0%, P = 0.016), and lower best PS rates (38.6% vs 81.0%, P < 0.001) than nonelderly patients. Lesion characteristics were similar in the 2 groups. The elderly had higher intraoperative hypotension rates (47.7% vs 21.4%, P = 0.011) and oxygen desaturation rates (9.1% vs 0.0%, P = 0.045) than nonelderly patients. In addition, the elderly also had a longer surgery time (107.0 ± 51.4 vs 91.5 ± 66.2 minutes, P = 0.049) and duration of hospitalization (7.5 ± 3.8 vs 5.9 ± 2.0 days, P = 0.016) than nonelderly patients. There were no differences in the prevalence rates of en-bloc resection, complete resection, bleeding, perforation, pneumonia, or intraabdominal free air between the 2 groups.Although elderly patients who underwent ESD for superficial gastric neoplasms had an increasing risk of intraoperative hypotension and oxygen desaturation, all patients were treated appropriately without postoperative sequelae. ESD is a safe and feasible intervention for elderly patients who have more comorbidity, a worse PS and more expanded lesions.

Abstract
AIM: To evaluate the pain relieving effect of intervention with “Lamaze method of colonoscopy” in the process of colonoscopy.
METHODS: Five hundred and eighty-five patients underwent colonoscopy were randomly divided into three groups, Lamaze group, anesthetic group and control group. Two hundred and twenty-four patients of Lamaze group, the “Lamaze method of colonoscopy” were practiced in the process of colonoscopy. The Lamaze method of colonoscopy is modified from the Lamaze method of childbirth, which helped patients to relieve pain through effective breathing control. One hundred and seventy-eight patients in anesthetic group accepted sedation colonoscopy. For 183 patients in control group, colonoscopy was performed without any intervention. The satisfactory of colon cleaning, intestinal lesions, intubation time, success ratio, pain grading and complications were recorded. All data were statistically analyzed.
RESULTS: There were no significant differences at base line of the three groups (P > 0.05). Anesthetic group shows advantage in intubation time than the other two groups (P < 0.05). Lamaze group shows no advantage in intubation time than that in control group (P > 0.05). The anesthetic group showed an apparent advantage in relieving pain (P < 0.01). Therefore, the “Lamaze method of colonoscopy” performed in colonoscopy could relieve pain effectively comparing with control group (P < 0.05). The patients in anesthetic group had the highest incidence of complications (P < 0.05).
CONCLUSION: The performance of the “Lamaze method of colonoscopy” in the process of colonoscopy could relieve patients’ pain, minimize the incidence of complications, and is worthy promotion in clinical practice.

Abstract
AIM: To compare the efficacy and safety of sedation protocols for endoscopic submucosal dissection (ESD) between dexmedetomidine-remifentanil and propofol-remifentanil.
METHODS: Fifty-nine patients scheduled for ESD were randomly allocated into a dexmedetomidine-remifentanil (DR) group or a propofol-remifentanil (PR) group. To control patient anxiety, dexmedetomidine or propofol was infused to maintain a score of 4-5 on the Modified Observer’s Assessment of Alertness/Sedation scale. Remifentanil was infused continuously at a rate of 6 μg/kg per hour in both groups. The ease of advancing the scope into the throat, gastric motility grading, and satisfaction of the endoscopist and patient were assessed. Hemodynamic variables and hypoxemic events were compared to evaluate patient safety.
RESULTS: Demographic data were comparable between the groups. The hemodynamic variables and pulse oximetry values were stable during the procedure in both groups despite a lower heart rate in the DR group. No oxygen desaturation events occurred in either group. Although advancing the scope into the throat was easier in the PR group (“very easy” 24.1% vs 56.7%, P = 0.010), gastric motility was more suppressed in the DR group (“no + mild” 96.6% vs 73.3%, P = 0.013). The endoscopists felt that the procedure was more favorable in the DR group (“very good + good” 100% vs 86.7%, P = 0.042), whereas patient satisfaction scores were comparable between the groups. En bloc resection was performed 100% of the time in both groups, and the complete resection rate was 94.4% in the DR group and 100% in the PR group (P = 0.477).
CONCLUSION: The efficacy and safety of dexmedetomidine and remifentanil were comparable to propofol and remifentanil during ESD. However, the endoscopists favored dexmedetomidine perhaps due to lower gastric motility.

Abstract
BACKGROUND Although endoscopic submucosal dissection (ESD) is routinely performed under sedation, the difference in ESD performance according to sedation method is not well known. This study attempted to prospectively assess and compare the satisfaction of the endoscopists and patient stability during ESD between two sedation methods. METHODS One hundred and fifty-four adult patients scheduled for ESD were sedated by either the IMIE (intermittent midazolam/propofol injection by endoscopist) or CPIA (continuous propofol infusion by anesthesiologist) method. The primary endpoint of this study was to compare the level of satisfaction of the endoscopists between the two groups. The secondary endpoints included level of satisfaction of the patients, patient's pain scores, events interfering with the procedure, incidence of unintended deep sedation, hemodynamic and respiratory events, and ESD outcomes and complications. RESULTS Level of satisfaction of the endoscopists was significantly higher in the CPIA Group compared to the IMIE group (IMIE vs. CPIA; high satisfaction score; 63.2% vs. 87.2%, P=0.001). The incidence of unintended deep sedation was significantly higher in the IMIE Group compared to the CPIA Group (IMIE vs. CPIA; 17.1% vs. 5.1%, P=0.018) as well as the number of patients showing spontaneous movement or those requiring physical restraint (IMIE vs. CPIA; spontaneous movement; 60.5% vs. 42.3%, P=0.024, physical restraint; 27.6% vs. 10.3%, P=0.006, respectively). In contrast, level of satisfaction of the patients were found to be significantly higher in the IMIE Group (IMIE vs. CPIA; high satisfaction score; 85.5% vs. 67.9%, P=0.027). Pain scores of the patients, hemodynamic and respiratory events, and ESD outcomes and complications were not different between the two groups. CONCLUSION Continuous propofol and remifentanil infusion by an anesthesiologist during ESD can increase the satisfaction levels of the endoscopists by providing a more stable state of sedation.

Abstract
BACKGROUND AND AIM Metachronous recurrence often occurs after endoscopic submucosal dissection for early gastric cancer, and a method for preventing recurrence is unknown. We aimed to identify risk factors for metachronous lesions, and the effects of aspirin use and Helicobacter pylori eradication on preventing recurrence. METHODS A total of 1041 consecutive patients who underwent endoscopic submucosal dissection for early gastric cancer between January 2007 and December 2011 were retrospectively analyzed. Every patient was examined endoscopically at 2, 6, and 12 months after endoscopic submucosal dissection, and then annually. Patients were classified into the metachronous group or non-metachronous group according to the existence of metachronous lesions and subdivided by Helicobacter pylori status into three groups: not infected, eradicated after infection, and not eradicated. RESULTS At 39 months' median follow-up, metachronous gastric lesions had developed in 35 patients (3.4%), including 16 with dysplasia and 19 cancers. Metachronous group were significantly older than non-metachronous group (P = 0.02). Although non-metachronous group took aspirin more frequently than metachronous group (15.5% vs 5.7%), the difference was statistically insignificant (P = 0.11). In the not eradicated group, the odds ratio of metachronous lesion was 7.762 compared with the not infected group (95% confidence interval, 1.483-60.854; P = 0.02). In the eradicated group, the odd ratio of metachronous lesion was 8.120 compared with not infected group (95% confidence interval, 1.950-58.985; P = 0.01). CONCLUSION Helicobacter pylori infection was an independent risk factor for metachronous gastric lesions. However, eradication of Helicobacter pylori alone does not prevent all metachronous lesions in an inflamed stomach.

The usage of overtube has a favorable effect on endoscopic submucosal dissection. Surg Endosc 2014; 29:2561-8.

Abstract
BACKGROUND Endoscopic submucosal dissection (ESD) may be very time consuming, and depending on the anesthesia, the contents of the stomach may reflux to the esophagus and cause the patient to aspirate. To prevent these situations, many practitioners suggest using an overtube, but no study has been done to evaluate the effect of the use of an overtube while performing the ESD procedure. Our aim was to investigate the effects of performing an upper gastrointestinal ESD with and without overtube. METHODS Records of patients who underwent ESD were evaluated for histopathological results, complications, speed of dissection, dosages of anesthetic medications, and number of suctions performed during the procedure. The patients were classified into two depending on whether an overtube was used or not. RESULTS There were a total of 58 patients on which 63 upper gastrointestinal ESD procedures were performed. Regarding age, gender, localization of the lesions, duration of the procedures, dosage of propofol, histopathological results, rate of complete resection, and rate of en-bloc resection, there was no difference between the two groups (p > 0,05). But the size of the lesions, the size of the resected specimen, and the speed of dissection were statistically different in two groups (p = 0.018, p < 0.001, p < 0.001, respectively).The need for suction during the procedure was much lower in the overtube group than those with no overtube (p < 0.001). CONCLUSIONS We conclude that using an overtube during an upper gastrointestinal ESD decreases the need for suction, favors the speed of dissection, and eases the comfort of the procedure.

Abstract
BACKGROUND Pneumonia following endoscopic procedures may affect the clinical course and prolong hospital stay. AIM To investigate the incidence and risk factors for pneumonia after endoscopic resection (ER) for gastric neoplasm. METHODS Subjects who underwent ER for gastric neoplasm at the Asan Medical Center from January 1997 to March 2013 were included. To investigate risk factors, control patients were randomly selected from these subjects. RESULTS Of the 7,149 subjects who underwent ER for gastric neoplasm, 44 (0.62 %) developed pneumonia. The median age of these 44 patients was 68 years (range 31-82 years), and the male to female ratio was 3:1. Twenty-five of the pneumonia patients (56.8 %) were smokers, and 8 (18.2 %) had underlying pulmonary diseases. The median procedure time was 23 min (range 2-126 min), and pathologic diagnoses included adenocarcinoma (n = 29), dysplasia (n = 10), and hyperplastic polyp (n = 5). Compared with the control group, smoking (current smoker vs. never smoker, odds ratio [OR] 2.366, p = 0.021), total procedure time (OR 1.011, p = 0.048), and hemostasis time (OR 1.026, p = 0.028) were risk factors for the development of pneumonia. In multivariate analysis, age >65 years (OR 2.073, p = 0.031), smoking (current smoker vs. never smoker, OR 2.324, p = 0.023), and hemostasis time (OR 1.025, p = 0.038) were independent risk factors. All patients recovered from pneumonia, and the duration of hospital stay did not differ between patients with pneumonia and the control group (p = 0.077). CONCLUSIONS Whereas old age, smoking, and longer hemostasis time are risk factors for pneumonia, its incidence after ER is not associated with clinically significant adverse outcomes.

Abstract
BACKGROUND Little is known about the clinical and oncologic outcomes of endoscopic submucosal dissection (ESD) compared with surgery in elderly patients with early gastric cancer (EGC). OBJECTIVE To evaluate the clinical and oncologic outcomes of ESD compared with surgery in elderly patients with EGC of an expanded indication. DESIGN Retrospective study with propensity-matched analysis. SETTING University-affiliated tertiary-care hospital, Seoul, South Korea. PATIENTS A total of 518 patients 70 years of age or older with initial-onset EGC. INTERVENTIONS ESD and surgery. MAIN OUTCOME MEASUREMENTS Clinical outcomes, disease-free survival, and overall survival. RESULTS In a propensity-matched analysis of 132 pairs, the length of hospital stay of the ESD group was shorter than that of the surgery group (median [interquartile range], 4 [3-4] vs 9 [7-11] days; P < .001). Intensive care unit admission occurred in the surgery group only (7 patients [5.3%]). Two surgery-related deaths occurred in the surgery group (1 splenic artery bleeding and 1 anastomosis site leakage). During follow-up, metachronous lesions developed more often in the ESD group than in the surgery group (12 vs 2 lesions, P = .004). All recurred lesions were successfully treated endoscopically except for 3 patients who refused additional treatment. Overall survival did not differ between the 2 groups (P = .280). LIMITATIONS Nonrandomized, retrospective study. CONCLUSIONS ESD is a safe procedure in elderly patients with EGC. Although the risk of metachronous lesions is higher in patients who undergo ESD than in those who undergo surgery, overall survival did not differ between the patients who undergo ESD and surgery.

Abstract
PURPOSE Endoscopic submucosal dissection (ESD) is a technically difficult and lengthy procedure requiring optimal depth of sedation. The bispectral index (BIS) monitor is a non-invasive tool that objectively evaluates the depth of sedation. The purpose of this prospective randomized controlled trial was to evaluate whether BIS guided sedation with propofol and remifentanil could reduce the number of patients requiring rescue propofol, and thus reduce the incidence of sedation- and/or procedure-related complications. MATERIALS AND METHODS A total of 180 patients who underwent the ESD procedure for gastric adenoma or early gastric cancer were randomized to two groups. The control group (n=90) was monitored by the Modified Observer's Assessment of Alertness and Sedation scale and the BIS group (n=90) was monitored using BIS. The total doses of propofol and remifentanil, the need for rescue propofol, and the rates of complications were recorded. RESULTS The number of patients who needed rescue propofol during the procedure was significantly higher in the control group than the BIS group (47.8% vs. 30.0%, p=0.014). There were no significant differences in the incidence of sedation- and/or procedure-related complications. CONCLUSION BIS-guided propofol infusion combined with remifentanil reduced the number of patients requiring rescue propofol in ESD procedures. However, this finding did not lead to clinical benefits and thus BIS monitoring is of limited use during anesthesiologist-directed sedation.

Abstract
BACKGROUND The optimal interval between endoscopic examinations for detecting early gastric neoplasms, including gastric adenomas, has not previously been studied. OBJECTIVE To clarify the optimal interval between endoscopic examinations for the early diagnosis of both gastric cancers and adenomas. DESIGN Retrospective study. SETTING University-affiliated tertiary-care hospital, Seoul, Korea. PATIENTS Patients who were treated for gastric neoplasms between January 2008 and August 2013. INTERVENTIONS Questionnaire survey for interval between the penultimate endoscopy and diagnosis of a gastric neoplasm. A total of 846 patients were divided into 5 groups according to the interval between endoscopic examinations. MAIN OUTCOME MEASUREMENTS The proportion of gastric neoplasms treated with endoscopic submucosal dissection and the proportion of advanced gastric cancers according to the interval between endoscopic examinations. RESULTS In total, 197, 430, and 219 patients were diagnosed with gastric adenoma, early gastric cancer, and advanced gastric cancer, respectively. In multivariate analysis, the proportion of gastric neoplasms treated with endoscopic submucosal dissection was significantly higher in the ≤12 months, 12 to 24 months, and 24 to 36 months endoscopy interval groups than in the no endoscopy within 5 years group (all P < .001). In addition, the proportion of advanced gastric cancers was significantly lower in the ≤12 months and 12 to 24 months endoscopy interval groups than in the no endoscopy within 5 years group (all P < .001). LIMITATIONS Retrospective study and recall bias. CONCLUSION Annual endoscopy cannot facilitate the detection of endoscopically treatable gastric neoplasms compared with biennial or triennial endoscopy. We recommend biennial endoscopic screening for gastric neoplasms in order to increase the proportion of lesions discovered while they are still endoscopically treatable and to reduce the number of lesions that progress to advanced gastric cancer.

Abstract
Gastric cancer remains one of the most common causes of cancer death. However the proportion of early gastric cancer (EGC) at diagnosis is increasing. Endoscopic treatment for EGC is actively performed worldwide in cases meeting specific criteria. Endoscopic mucosal resection can treat EGC with comparable results to surgery for selected cases. Endoscopic submucosal dissection (ESD) increases the en bloc and complete resection rates and reduces the local recurrence rate. ESD has been performed with expanded indication and is expected to be more widely used in the treatment of EGC through the technological advances in the near future. This review will describe the techniques, indications and outcomes of endoscopic treatment for EGC.

[PMID: 24765596 PMCID: PMC3994256 DOI: 10.5946/ce.2014.47.2.141] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/25/2014] [Revised: 02/25/2014] [Accepted: 02/26/2014] [Indexed: 12/24/2022] Open
Abstract
Adequate sedation and analgesia are considered essential requirements to relieve patient discomfort and pain and ultimately to improve the outcomes of modern gastrointestinal endoscopic procedures. The willingness of patients to undergo sedation during endoscopy has increased steadily in recent years and standard sedation practices are needed for both patient safety and successful procedural outcomes. Therefore, regular training and education of healthcare providers is warranted. However, training curricula and guidelines for endoscopic sedation may have conflicts according to varying legal frameworks and/or social security systems of each country, and well-recognized endoscopic sedation training systems are not currently available in all endoscopy units. Although European and American curricula for endoscopic sedation have been extensively developed, general curricula and guidelines for each country and institution are also needed. In this review, an overview of recent curricula and guidelines for training and basic performance of endoscopic sedation is presented based on the current literature.

Park CH, Lee SK. Preventing and controlling bleeding in gastric endoscopic submucosal dissection. Clin Endosc 2013; 46:456-62. [PMID: 24143302 PMCID: PMC3797925 DOI: 10.5946/ce.2013.46.5.456] [Citation(s) in RCA: 33] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/27/2013] [Accepted: 07/04/2013] [Indexed: 02/06/2023] Open
Abstract
Although techniques and instruments for endoscopic submucosal dissection (ESD) have improved, bleeding is still the most common complication. Minimizing the occurrence of bleeding is important because blood can interfere with subsequent procedures. Generally, ESD-related bleeding can be divided into intraprocedural and postprocedural bleedings. Postprocedural bleeding can be further classified into early post-ESD bleeding which occurs within 48 hours after ESD and late post-ESD bleeding which occurs later than 48 hours after ESD. A basic principle for avoiding intraprocedural bleeding is to watch for vessels and coagulate them before cutting. Several countertraction devices have been designed to minimize intraprocedural bleeding. Methods for reducing postprocedural bleeding include administration of proton-pump inhibitors or prophylactic coagulation after ESD. Medical adhesive spray such as n-butyl-2-cyanoacrylate is also an option for preventing postprocedural bleeding. Various endoscopic treatment modalities are used for both intraprocedural and postprocedural bleeding. However, hemoclipping is infrequently used during ESD because the clips interfere with subsequent resection. Bleeding that occurs as a result of ESD can usually be managed easily. Nonetheless, more effective ways to prevent bleeding, including reliable ESD techniques, must be developed.
