ABSTRACT
Corrosive injuries (CI) become medical problems related complications include esophageal, pyloric stricture and squamous cell carcinoma, physical and quality of life. Endoscopic (ED) dilatation is primary therapy. The ultrathin endoscope-assisted method is potentially safe and useful in avoiding technical failure. Describe clinical outcomes of ED ED-related CI including successful, refractory, recurrent, and complications-related procedures. Case series study of esophageal and/or pyloric stricture patients after CI who underwent dilatation at Soetomo General Hospital (July 2018 - July 2022). One - biweekly ED using Through The Scope (TTS) balloon or Savary Bougie dilator. The target diameter is 14mm. Fifteen patients with stricture-related CI. Eleven patients underwent ED with a total of 73 procedures. Mean age 31,45 years, predominantly male patients (6), suicide attempt (7), acid agent (9), located at esophagus (3), pylorus (3), or both (5). Number of esophageal dilatation to achieve the target of 14 mm was 1-2 and 2-15 procedures for simple and complex stricture. Five esophageal strictures were successfully dilated but 2 patients were recurrent and 3 cases were refractory to ED. Pyloric dilatation resulted in a lower success rate. Recurrent and refractory cases were 5 and 3 patients respectively. ED with ultrathin endoscope method is useful for traversing guidewire during ED. Ongoing inflammation and fibrosis were linked to recurrent and refractory stricture.

Objective:To investigate the surgical outcomes and safety of the follower arm endoscope holder in assisting type â tympanoplasty. Methods:The clinical data of 16 patients who underwent type â tympanoplasty at the Department of Otorhinolaryngology, Peking Union Medical College Hospital, from November 2022 to September 2023 were retrospectively analyzed, among which 8 cases were operated by traditional otoscopy and 8 cases were operated by supported endoscopy.The surgical procedure was analyzed and the completion of supported endoscopic operation was observed, while the duration of the operation, the time consumed by the main steps, the frequency of wiping the lenses, the perioperative complications, and the improvement of the postoperative hearing were recorded and statistically analyzed. Results:Supporting endoscopic technology achieved real-time suction of bleeding, simultaneous traction and separation of tissues, precise removal of calcified spots on the inner side of the eardrum, trimming of the external auditory canal flap, stable separation of the handle of the malleus and the eardrum, and tensioned repositioning of the skin-cartilage flap. The average duration of surgery, time for external auditory canal flap preparation, and time for repositioning the skin-cartilage flap were reduced in the supporting endoscopic surgery group compared to the control group. The average lens wiping frequency was significantly lower in the supporting endoscopic surgery group compared to the control group. There was no statistically significant difference in postoperative hearing improvement between the two groups, and no infections or the need for secondary surgery due to eardrum re-perforation occurred postoperatively. Conclusion:Supported endoscopy technology realizes the need for endoscopic two-handed operation and convenient switching between one and two hands, accomplishes many operations that cannot be done by traditional endoscopic surgery, solves the problems of previous intraoperative one-handed operation and image instability, shortens the average operation time compared with traditional otoscopic surgery, and decreases the frequency of intraoperative wiping of the lens significantly compared with traditional otoscopic surgery, which is potentially worthwhile in terms of shortening the learning curve.

BACKGROUND: This study aimed to conduct a case-control study of endoscopic and fluoroscopic metal stent placement combined with laparoscopic surgery versus conventional open Hartmann's procedure in treating acute left-sided colon cancer obstruction. Additionally, the study aims to discuss the application value of endoscopic and X-ray-guided metal stent placement combined with laparoscopic surgery in the treatment of acute left-sided colon cancer obstruction. METHODS: From June 2011 to December 2019, 23 patients with acute left-sided colon cancer obstruction who underwent metal stent implantation combined with laparoscopic surgery under endoscopy and X-ray fluoroscopy in Wenzhou Central Hospital were collected, and 20 patients with acute left-sided colon cancer obstruction who underwent traditional emergency open Hartmann's surgery during the same period were selected as a control group. All patients were diagnosed with left colon obstruction by plain abdominal film and/or CT before the operation and colon adenocarcinoma by colonoscopic biopsy and/or postoperative pathology. The operation time, intraoperative blood loss, postoperative anal exhaust time, the success rate of one-stage anastomosis, postoperative hospital stay, and postoperative complications were compared between the two groups. RESULTS: This study showed a significant difference in the therapeutic effect between the two groups. Compared with the traditional Hartmann's operation group, the success rate of one-stage anastomosis in endoscopic and X-ray-guided metal stent placement combined with the laparoscopic operation group was significantly higher than that in the Hartmann's operation group (P < 0.05). The overall incidence of postoperative complications and hospital stay were significantly lower in the observation group than in the Hartmann's group (P < 0.05). Further subgroup analysis of the overall postoperative complication rate of the two groups showed that the traditional Hartmann's operation group was more likely to have an incomplete intestinal obstruction (P < 0.05). This study also showed no significant differences between the two groups in operation time, intraoperative blood loss, number of harvested lymph nodes, and postoperative anal exhaust time (all P > 0.05). This study also found no significant differences between the two groups in overall survival rates or recurrence-free survival rates (all P > 0.05). CONCLUSIONS: The comparison of the therapeutic effects of the two groups verified the feasibility of endoscopy combined with X-ray fluoroscopy metal stent placement in combination with laparoscopic surgery in the treatment of acute left-sided colon cancer obstruction. Compared with the traditional emergency open Hartmann's procedure, metal stent implantation under endoscopy and X-ray fluoroscopy combined with laparoscopic surgery is more minimally invasive, safe, and effective. It avoids the traditional second or even third surgical trauma to effectively improve the quality of life of patients, so that patients can recover quickly after surgery.

BACKGROUND AND AIMS: Self-expandable metallic stents (SEMS) can be used to treat malignant colorectal obstruction (MCO). Guidewire insertion to the proximal site of MCO is the most important step for SEMS placement. However, some patients cannot undergo guidewire insertion because of total obstruction or location at anatomically challenging areas. We report a guidewire insertion technique using an ultrathin endoscope (UTE) in patients with MCO in whom conventional SEMS insertion failed. METHODS: This study was a retrospective cohort study conducted at three academic centers in Korea. The medical records of 956 consecutive patients who underwent SEMS placement during 2012-2021 were analyzed. After failing guidewire insertion using a colonoscope, a UTE was inserted. Guidewire insertion was done through the working channel of the UTE. Following guidewire insertion, the endoscope was removed from the patient. While removing the endoscope, the guidewire was advanced to be located at the originally inserted site. Then, the colonoscope was inserted over the guidewire, and SEMS was replaced. RESULTS: Conventional SEMS insertion failed in 75 patients. Of these, guidewire insertion using a UTE was tried in 59 patients. The rate of technical success was 91.5% (54/59). Considering all patients, the overall technical success rate of SEMS placement was 97.8% (935/956). This technique increased the technical success rate by 5.6% among the total cohort. CONCLUSIONS: The UTE facilitated guidewire insertion and enhanced the overall success rate for SEMS placement. In addition, this technique can be used as a rescue method when guidewire insertion fails using a colonoscope.

INTRODUCTION: Spontaneous intraparenchymal brain hemorrhages are a devastating disease associated with significant disability or death. Minimally invasive clot evacuation (MICE) techniques can reduce mortality. We reviewed our experience with learning endoscope-assisted MICE to determine whether adequate results could be obtained in less than 10 cases. METHODS: We performed a retrospective chart review of patients undergoing endoscope-assisted MICE at a single institution by a single surgeon from January 1, 2018 to January 1, 2023 using a neuro-endoscope, a commercial clot evacuation device, and frameless stereotaxis. Demographic data was collected along with surgical results and complications. Image analysis using software determined the degree of clot removal. Hospital length of stay and functional outcomes were assessed using the Glasgow Coma Scale score (GCS) and Glasgow Outcome Score (extended) (GOS-E). RESULTS: Eleven patients were identified: average age 60.82 years old, 64 % male, all had hypertension. There was a clear improvement in IPH evacuation over the series. By case #7, greater than 80 % of clot volume was evacuated consistently. All patients remained neurologically stable or improved following surgery. In long-term follow-up, four patients (36.4 %) had good outcomes (GOS-E ≥ 6) and 2 patients had fair outcomes (GOS-E = 4) (18 %). There were no surgical mortalities, re-hemorrhages, or infections. CONCLUSIONS: With an experience of less than 10 cases, it is possible to obtain results comparable to most published series of endoscope-assisted MICE. Benchmarks such as greater than 80 % volume removal, less than 15 mL residual, and 40 % good functional outcomes can be obtained.

OBJECTIVE: As a complex and acute brain dysfunction, if postoperative delirium (POD) occurs in the postoperative period, it will lead to a prolonged length of stay in the critical care unit, with increased hospitalization costs and higher mortality. A few case reports inspired us to pay close attention to pituitary tumor-associated delirium. We hypothesized that the changes in hormone levels after pituitary tumor resection might be associated with POD occurrence. METHODS: Retrospective analysis was performed on data from a single-center cohort study conducted at Southwest Hospital between January 2018 and May 2022. A total of 360 patients with pituitary tumors who underwent endoscope-assisted transsphenoidal pituitary tumor resection were divided into two groups at a 1:3 ratio, with 36 patients in the POD group and 108 patients in the non-POD group matched by propensity score, age, sex, and tumor size. Basic characteristics, pituitary adenoma features, endocrine levels and other biochemical indicators, and Confusion Assessment Method for the Intensive Care Unit (CAM-ICU) for postoperative delirium were documented for further analysis. RESULTS: Lower insulin-like growth factor-1 (IGF-1, p = .024) and corticotropin-releasing hormone (CRH, p = .005) levels were closely associated with postoperative delirium and with high levels of blood glucose (GLU, p = .023) after surgery. Subsequent analysis indicated that serum potassium (OR: 0.311, 95% CI 0.103-0.935), sodium (OR: 0.991, 95% CI 0.983-1.000), CRH (OR: 0.964, 95% CI 0.936-0.994), and GLU (OR: 1.654, 95% CI 1.137-2.406) levels in the perioperative period were independent risk factors for delirium. CONCLUSIONS: Our study indicated that lower serum CRH, potassium, sodium, and GLU levels may be associated with the occurrence of POD after endoscopic-assisted transsphenoidal surgery. These data provide preliminary evidence for the management of POD in pituitary adenoma patients after surgery. Further studies are needed to identify pharmacological and nonpharmacological multicomponent treatment strategies.

OBJECTIVES: Medical device-related pressure ulcer (MDRPU) is a skin or subcutaneous tissue injury caused by medical devices. Skin protectants have been used to prevent MDRPU in other fields. In endoscopic sinonasal surgery (ESNS), rigid endoscopes and forceps can cause MDRPU; however, detailed investigations have not been conducted. This study aimed to investigate the frequency of MDRPU in ESNS and the preventive effects of skin protectants METHODS: Thirty-nine patients who received ESNS and consented to study participation were randomly assigned to the "protective agent" (n = 18) or "control" (n = 21) group. MDRPU presence around the nostril was evaluated for up to 7 days post-surgically based on physical findings and subjective symptoms. The occurrence ratio and severity of MDRPU were statistically compared between the groups to evaluate the efficacy of skin protective agents. RESULTS: Stage 1 MDRPU, according to the National Pressure Ulcer Advisory Panel classification, was seen in 20.5% (8/39) of the patients, and no patient had more high-grade ulceration. On postoperative days 2 and 3, skin erythema was predominantly observed on the nasal floor, with a comparatively lower incidence in the protective agent group. Significant pain reduction was observed in the nostril's floor on postoperative days 2 and 3 in the protective agent group. CONCLUSIONS: MDRPU occurred with a relatively high frequency around the nostrils after ESNS. Protective agent use in the external nostrils was effective especially in reducing post-operative pain on the nasal floor, where tissue damage can easily occur due to device-related friction.

PURPOSES: To evaluate clinical usefulness of endoscope-assisted medial orbital wall fracture repair via the retrocaruncular approach (rc-EAMOWFR) vs. no surgery (NS), and to perform a narrative review of relevant literature. METHODS: This was a retrospective cohort study enrolling isolated medial orbital wall fracture (IMOWF) eyes presented to two German level 1 trauma centers during a 7-year interval. The predictor variable was treatment type (rc-EAMOWFR vs. NS), and the main outcomes were late enophthalmos (LE) and retrobulbar hemorrhage (RH) assessed at 9-15 posttraumatic months. Descriptive and bivariate statistics were computed at α = 95%. Binary adjustments enabled calculation of number needed to treat (NNT), to harm (NNH), and likelihood to be helped or harmed (LHH) for demonstrating benefit-risk tradeoffs. Moreover, a narrative review was also performed. RESULTS: The sample comprised 502 patients (28.3% females; mean age, 46.5±19.2 years) with 541 IMOWF eyes (5.9% NS; 7.2% LE; 1.3% RH). Operated eyes had significantly lower LE events than NS eyes (symptomatic IMOWF: P < .0001; 95% confidence interval [CI], .03 to .16; NNT = 2 [95% CI, 1.1 to 6.1]; asymptomatic IMOWF: P < .0001; 95% CI, .01 to .07; NNT = 2 [95% CI, 1.1 to 1.8]). There were 7 (1.5%) RH events following rc-EAMOWFR (P = .99; 95% CI, .06 to 17.4; NNH = 68 [95% CI, 38.3 to 254.2]). LHH calculations posited that rc-EAMOWFR was 34 times more likely to prevent LE than to cause RH, regardless of fracture symptoms. Our results conformed to those of other 15 studies. CONCLUSIONS: The results of this study suggest that all IMOWFs be treated. rc-EAMOWFR performed in every 68 IMOWFs would be at risk of one RH event, but prevent 34 eyes from LE due to untreated fractures. Nearly 72% of untreated IMOWFs develop LE after 9 months.

OBJECTIVE: To investigate combined external ventricular drainage and endoscope-assisted microsurgery using the middle frontal gyrus approach in patients with severe ventricular hemorrhage with casting of the fourth ventricle and patients' recovery after this treatment. METHODS: Patients with severe ventricular hemorrhage with casting of the fourth ventricle (n = 41) were randomly assigned to intervention and control groups. Modified Graeb score was used to assess 3-day hematoma clearance rate before and after surgery, drainage tube extubation time for the 2 groups was compared, and time when blood clot in the fourth ventricle was not blocked with cerebrospinal fluid was compared. Glasgow Coma Scale was used to assess consciousness after surgery; Glasgow Coma Scale scores recorded 1 and 7 days after surgery were also compared. Modified Rankin Scale was used to evaluate patients' recovery 1 and 6 months after surgery. Hydrocephalus and intracranial infections in patients after surgery were recorded for 90 days. RESULTS: The 3-day hematoma clearance rate was dramatically higher in the intervention group. Modified Graeb score showed that more hemorrhage was delimited in 3 days in the intervention group. The intervention group exhibited significantly reduced length of block of the fourth ventricle and drainage tube extubation time. High Glasgow Coma Scale and modified Rankin Scale scores and significantly low incidence of complications (e.g., hydrocephalus and intracranial infection) were observed in patients in the intervention group. CONCLUSIONS: Combined external ventricular drainage and endoscope-assisted microsurgery using the middle frontal gyrus approach can effectively improve severe ventricular hemorrhage with casting of the fourth ventricle and enhance patients' neurological function and recovery.

BACKGROUND: Muscular calf hypertrophy can cause severe psychological distress. Total or subtotal resection of the gastrocnemius muscle results in significant calf reduction. However, both techniques require a second incision of 5 and 2 cm, respectively, at the posterior mid-calf. The resultant mid-calf scar is more difficult to conceal when wearing short skirts or pants. OBJECTIVES: The authors sought to describe the technique of endoscope-assisted gastrocnemius muscle resection to obviate the need for a mid-calf scar and to review the outcomes of patients who underwent this procedure. METHODS: A retrospective study of 300 patients in a single center in Taiwan who underwent endoscope-assisted subtotal resection of the gastrocnemius muscle for hypertrophic muscular calves, between March 2015 to June 2019, were included in this study. RESULTS: The combined weight of the resected gastrocnemius muscle ranged from 156 to 484 g per calf (mean = 276 g). The mean maximal calf circumference was 36.1 cm preoperatively and 30.9 cm postoperatively. The calf reduction achieved was 3.0 to 8.1 cm (mean = 5.2 cm), or 8.9% to 19.8% (mean = 14.4%). The complications were minor, and the rate was low (2%). As for the popliteal fossa scar, 6 patients underwent further treatment of their hyperpigmented or hypertrophic transverse scar. There were no complaints of impaired leg function regarding gait or sports activities 3 to 6 months postoperatively. CONCLUSIONS: At present, gastrocnemius muscle resection remains unrivaled in its ability to achieve calf reduction. The surgery is now much more appealing to patients as a result of employing the endoscope-assisted technique to obviate the mid-calf scar.

OBJECTIVE: We sought to compare the effect of applying a 5-mm endoscope and a 10-mm endoscope in the transoral endoscopic thyroidectomy vestibular approach (TOETVA) and to clarify the advantages of using a 5-mm endoscope. MATERIALS AND METHODS: A retrospective analysis of the clinical data of 135 patients who were diagnosed with papillary thyroid carcinoma and who had undergone TOETVA in the thyroid disease center of The First Affiliated Hospital of Nanchang University between January 2019 and May 2020 was performed. Among the included patients, a 10-mm endoscope was used in 50 cases (the 10-mm endoscope group) and a 5-mm endoscope was used in 85 cases (the 5-mm endoscope group), respectively. Operative trauma, operative parameters, postoperative complications, and postoperative mandibular sensation score were compared and analyzed. RESULTS: Compared with the 10-mm endoscope group, the 5-mm endoscope group had less surgical trauma, less injury to the mandibular muscles (orbicularis oris, depressor labii inferioris, and mentalis muscle), shorter operative times (107.7±8.1 vs. 121.3±11.6 min, P<0.01), less intraoperative bleeding (14.3±4.8 vs. 17.9±5.3 mL, P<0.01), no obvious postoperative complications, lower mandibular sensation score values (5.7±0.6 vs. 6.0±0.4 points, P<0.01), and shorter mandibular recovery times (9.4±2.5 vs. 12.3±3.6 d, P<0.01). CONCLUSION: The application of a 5-mm endoscope not only improves the cosmetic effect of TOETVA but also reduces the degree of surgical trauma, saves the surgical space, improves the surgical efficiency, and reduces postoperative discomfort, with a promising application prospect.

PURPOSE: Endoscope-assisted transsphenoidal surgery over the last few years has led to more radical excision of pituitary adenomas (PAs) with a low complication rate. Systematic registration of complications by experienced surgical teams could help to improve this technique while ameliorating the patients' quality of life. MATERIALS AND METHODS: One hundred ten endoscopic procedures were performed in 94 patients with PAs (37 functional) by the same neurosurgical team of a tertiary center during the period 2014-2019. Post-surgical complications were analyzed and compared with data published during the last 5 years in the PubMed and Cochrane databases by performing a systematic review and meta-analysis of the literature. RESULTS: The overall complication rate in our series was 23.4%. Diabetes insipidus (DI) and intraoperative cerebrospinal fluid (CSF) leakage were the commonest complications (12.8%), followed by postoperative hypopituitarism (9.2%) and hematoma (8.5%) during the follow-up of 2.15 ± 1.4 years. Syndrome of inappropriate antidiuretic hormone secretion, meningitis, deep vein thrombosis, and hyposmia were rare (< 3%). Postoperative hypopituitarism was significantly associated with incidence of hematoma. No statistically significant association was found between PAs Hardy and Knosp scale grading or between patients' characteristics with the occurrence of postoperative complications. Our meta-analysis including nine studies found no significant differences comparing the complications of endoscopic versus microscopic surgery. CONCLUSION: The endoscopic approach is safe when performed by experienced surgical teams. CSF leakage and DI were the commonest complications in our series; however, confirmation by larger studies is required. Meta-analysis showed no statistically significant differences in complication rates comparing endoscopic versus microscopic surgery.

OBJECTIVE: To evaluate retrospectively the incidence of complications during fiberoptic endoscopic evaluation of swallowing (FEES) in 5,680 examinations. PATIENTS AND METHODS: 5,680 patients were evaluated at the Department of Otorhinolaryngology, Audiology and Phoniatrics of Pisa University Hospital between January 2014 and December 2018, involving both inpatients and outpatients. Most common comorbidities included neurological pathologies such as stroke (11.8%), neurodegenerative diseases (28.9%) and a history of previous head and neck surgery (24.6%). The evaluation was conducted by clinicians with experience in swallowing for a minimum of 10 years with the assistance of one or more speech-language pathologists. RESULTS: In all patients studied the endoscope insertion was tolerated, and it was possible to visualize the pharyngolaryngeal structures. Three subjects refused to undergo the procedure after being informed regarding the protocol and were therefore not included in this study. Most patients reported discomfort (70.1%) and gagging (20.8%). In a minority of patients complications were recorded, such as anterior epistaxis (0.1%), posterior epistaxis (0.02%), vasovagal crises (0.08%) and laryngospasm (0.04%). Especially laryngospasm was recorded in patients affected by amyotrophic lateral sclerosis. Multivariate binary logistic regression showed that discomfort (OR 9.944; CI 7.643-12.937), chronic gastrointestinal diseases (OR 2.003; CI 1.518-2.644), neurodegenerative diseases (OR 1.550; CI 1.302-1.846) and brain tumors (OR 1.577; CI 1.179-2.111) were risk factors associated with minor complications. CONCLUSIONS: FEES proved to be easy to perform, well tolerated by the patients and cost-effective. It can be performed at the patient's bedside, and it is characterized by a low rate of complications. As a matter of fact, normally only discomfort, gagging and/or vomiting are reported. Complications occurred only rarely, such as anterior or posterior epistaxis episodes or vasovagal crises, but these are still easily managed. Exceptionally, more severe complications are reported: adverse drug reactions to substances such as blue dye (methylene blue) and local anesthetics (not used in our protocol), and laryngospasm.

A 76-year-old female who had a history of endovascular treatment (EVT) for her left superficial femoral artery with endovascular stent grafts [VIABAHN (W. L. Gore & Associates, Inc., DE, USA)] suddenly experienced intermittent claudication of her left leg. Angiography revealed total occlusion of previous stent grafts, and a thrombus aspiration catheter was used after crossing the guidewire. Since retrograde angiography using a thrombus aspiration catheter revealed a large residual thrombus at the distal edge of the previous stent even after several thrombus aspirations, biopsy forceps for intestinal endoscopes [Radial Jaw (Boston Scientific, MA, USA)] were successfully used to remove that thrombus. After balloon inflation under distal protection, angiography revealed a large residual thrombus at her left common femoral artery with a flow limiting of her deep femoral artery. Again, biopsy forceps were successfully used to remove that thrombus. In this case series, we reported a total of 11 cases which underwent EVT using biopsy forceps for intestinal endoscopes [Radial Jaw (Boston Scientific, MA, USA)]. Of the 11 cases, eight underwent EVT using biopsy forceps for thrombus removal, two underwent calcification removal in severely calcified lesions, and one underwent removal of a detached guidewire. There were no major adverse limb events (MALEs) except for one patient who underwent major amputation after EVT. One MALE occurred independently of biopsy forceps use because biopsy forceps were used only to remove the detached wire. Biopsy forceps for intestinal endoscopes were clinically useful and safe for EVT.

This study aimed to critically review pediatric swallowing assessment data to determine the future need for standardized procedures. A retrospective analysis of 152 swallowing examinations in 128 children aged 21 days to 18 years was performed. The children were presented at a university dysphagia center between January 2015 and June 2020 for flexible-endoscopic evaluation of swallowing (FEES). Descriptive analysis was conducted for the sample, swallowing pathologies, diagnosis, and missing values. Using binary logistic regression, the relationship between dysphagia and underlying diseases was investigated. The largest group with a common diagnosis in the cohort were children with genetic syndromes (n = 43). Sixty-nine children were diagnosed with dysphagia and 59 without dysphagia. The non-dysphagic group included 15 patients with a behavioral feeding disorder. The presence of an underlying disease significantly increased the chance of a swallowing problem (OR 13.08, 95% CI 3.66 to 46.65, p = .00). In particular, the categories genetic syndrome (OR 2.60, 95% CI 1.15 to 5.88) and neurologic disorder (OR 4.23, 95% CI 1.31 to 13.69) were associated with higher odds for dysphagia. All pediatric FEES were performed without complications, with a completion rate of 96.7%, and with a broad variability of implementation. Several charts lacked information concerning swallowing pathologies, though. Generally, a more standardized protocol and documentation for pediatric FEES is needed to enable better comparability of studies on epidemiology, assessment, and treatment outcomes in future.

Over the past 2 decades, in hospital centers worldwide, there have been numerous outbreaks of multidrug-resistant organisms that have since been attributed to endoscopic transmission of the infections between patients, primarily from duodenoscopes. These outbreaks have focused the attention of endoscope manufacturers, professional societies, and regulatory agencies on improving the reprocessing of these devices. The key steps in this process are point-of-use precleaning, leak testing, manual cleaning, high-level disinfection, and finally drying and storage. The promise of these initial efforts suggest that the aim of minimizing and ultimately eliminating events of endoscope-/duodenoscope-associated transmission of infectious organisms between patients can be achieved.

Several factors affect the efficacy of endoscope reprocessing, including human factors, inadequate cleaning, simethicone residuals, moisture in channels during storage, and biofilm or buildup biofilm formation. These factors all contribute to contamination of patient-ready endoscopes that may contribute to transmission of microorganisms resulting in infection and/or colonization. This article reviews monitoring as part of a quality management system that includes manual cleaning, dry storage, and culture to detect endoscope contamination. The published data for rapid tests that detect organic residuals and adenosine triphosphate to monitor manual cleaning are reviewed.

After outbreaks of duodenoscope-transmitted infection with multidrug-resistant organisms, it has become clear that institutions must optimize their endoscope reprocessing programs. Standard endoscope reprocessing practices may not represent the ideal approach for preventing transmission of infection related to endoscopy. We discuss multiple approaches to enhance and optimize reprocessing, drying, and storage of standard duodenoscopes. The optimal enhanced duodenoscope reprocessing modality remains to be determined. Acknowledging the challenges and limitations in effectively reprocessing duodenoscopes, the FDA issued a safety communiqué recommending transitioning to either single use disposable duodenoscopes or duodenoscopes with innovative designs that allow more effective reprocessing.

Transmission of pathogens during endoscopy and subsequent outbreak investigations generated by potential nosocomial transmissions have become a major concern for gastroenterologists. These investigations have resulted in significant media coverage for individual institutions and can cause massive disruption to the institution if not handled well. Gastroenterologists should have a central role in investigation of these outbreaks and management of the communications and patient notification that is required. This article summarizes important aspects of outbreak investigations for physicians who do not frequently manage these investigations and gives practical advice for how gastroenterologists can help identify outbreaks and manage these investigations successfully.
