Abstract
BACKGROUND Low anterior resection syndrome has a negative impact on quality of life. Intestinal irrigation is a method of lavage consisting of a scheduled evacuation. OBJECTIVE This study aims to evaluate functional and quality-of-life outcomes in patients with low anterior resection syndrome after transanal irrigation using a colostomy irrigation system. DESIGN This was a prospective case series. SETTINGS This study presents a single-center experience at a tertiary oncological center in an upper-middle-income country. PATIENTS Patients classified as having minor or major low anterior resection syndrome 12 months after their operation were selected. INTERVENTIONS Transanal irrigation was performed using an ostomy irrigation kit. Questionnaires assessing patients' bowel function (low anterior resection syndrome and Wexner score) and quality of life (Short Form-36 questionnaire) were applied before and after treatment. MAIN OUTCOME MEASURES The primary outcomes were low anterior resection syndrome score and quality-of-life improvement after a 12-month treatment. RESULTS Of the 22 patients included, 20 had major and 2 had minor low anterior resection syndrome, with a median score of 39, especially high rates of incontinence for liquid stool (21; 95.5%), clustering (21; 95.5%), and urgency (17; 77.3%). All patients successfully completed the 3-day training, and there were no complications during the treatment. After the 12-month period, the median score was 8, with 90% of the patients classified as having "no syndrome" and great improvement in all domains of this score. The most improved quality-of-life sections were patient vitality (p = 0.025) and physical (p = 0.002), social (p = 0.001), and emotional aspects (p = 0.001). LIMITATIONS The study was limited by its small sample size and the limited follow-up period. CONCLUSIONS This study presents a safe implementation protocol of an ostomy irrigation device for transanal irrigation. It also adds to the literature that transanal irrigation is a safe, effective, and easily implemented procedure for patients with low anterior resection syndrome with a significant improvement in quality of life.

Abstract
Disorders of bowel function are prevalent, particularly among patients with spinal cord injuries and other neurological disorders. An individual's bowel control significantly impacts quality of life, as predictable bowel function is necessary to actively and independently participate in everyday activities. For many patients with bowel dysfunction, initial lifestyle adjustments and other conservative therapeutic interventions (eg, digital stimulation, oral laxatives, suppositories) are insufficient to reestablish regular bowel function. In addition to these options, rectal irrigation (RI) is a safe and effective method of standard bowel care that has been used for several decades in adults and children suffering from bowel dysfunction associated with neurogenic or functional bowel etiologies. Rectal irrigation is an appropriate option when conservative bowel treatments are inadequate. Unlike surgical options, RI can be initiated or discontinued at any time. This report summarizes the clinical, humanistic, and economic evidence supporting the use of RI in clinical practice, noting features (eg, practical considerations, patient education) that can improve patients' success with RI treatment.

Abstract
IMPORTANCE Colorectal cancer (CRC) remains a significant cause of morbidity and mortality in the US. OBJECTIVE To systematically review the effectiveness, test accuracy, and harms of screening for CRC to inform the US Preventive Services Task Force. DATA SOURCES MEDLINE, PubMed, and the Cochrane Central Register of Controlled Trials for relevant studies published from January 1, 2015, to December 4, 2019; surveillance through March 26, 2021. STUDY SELECTION English-language studies conducted in asymptomatic populations at general risk of CRC. DATA EXTRACTION AND SYNTHESIS Two reviewers independently appraised the articles and extracted relevant study data from fair- or good-quality studies. Random-effects meta-analyses were conducted. MAIN OUTCOMES AND MEASURES Colorectal cancer incidence and mortality, test accuracy in detecting cancers or adenomas, and serious adverse events. RESULTS The review included 33 studies (n = 10 776 276) on the effectiveness of screening, 59 (n = 3 491 045) on the test performance of screening tests, and 131 (n = 26 987 366) on the harms of screening. In randomized clinical trials (4 trials, n = 458 002), intention to screen with 1- or 2-time flexible sigmoidoscopy vs no screening was associated with a decrease in CRC-specific mortality (incidence rate ratio, 0.74 [95% CI, 0.68-0.80]). Annual or biennial guaiac fecal occult blood test (gFOBT) vs no screening (5 trials, n = 419 966) was associated with a reduction of CRC-specific mortality after 2 to 9 rounds of screening (relative risk at 19.5 years, 0.91 [95% CI, 0.84-0.98]; relative risk at 30 years, 0.78 [95% CI, 0.65-0.93]). In observational studies, receipt of screening colonoscopy (2 studies, n = 436 927) or fecal immunochemical test (FIT) (1 study, n = 5.4 million) vs no screening was associated with lower risk of CRC incidence or mortality. Nine studies (n = 6497) evaluated the test accuracy of screening computed tomography (CT) colonography, 4 of which also reported the test accuracy of colonoscopy; pooled sensitivity to detect adenomas 6 mm or larger was similar between CT colonography with bowel prep (0.86) and colonoscopy (0.89). In pooled values, commonly evaluated FITs (14 studies, n = 45 403) (sensitivity, 0.74; specificity, 0.94) and stool DNA with FIT (4 studies, n = 12 424) (sensitivity, 0.93; specificity, 0.85) performed better than high-sensitivity gFOBT (2 studies, n = 3503) (sensitivity, 0.50-0.75; specificity, 0.96-0.98) to detect cancers. Serious harms of screening colonoscopy included perforations (3.1/10 000 procedures) and major bleeding (14.6/10 000 procedures). CT colonography may have harms resulting from low-dose ionizing radiation. It is unclear if detection of extracolonic findings on CT colonography is a net benefit or harm. CONCLUSIONS AND RELEVANCE There are several options to screen for colorectal cancer, each with a different level of evidence demonstrating its ability to reduce cancer mortality, its ability to detect cancer or precursor lesions, and its risk of harms.

J Clin Med 2020; 9:jcm9103141. [PMID: 32998474 PMCID: PMC7599469 DOI: 10.3390/jcm9103141] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2020] [Revised: 09/07/2020] [Accepted: 09/11/2020] [Indexed: 12/02/2022] Open
Abstract
Background: Marfan’s syndrome (MFS) seems to be frequently associated with colonic diverticulosis, but the prevalence of diverticula and symptoms evocative of diverticular disease in this population are still unknown. Methods: This prospective case control study included 90 consecutive patients with MFS, 90 unselected controls, and 90 asymptomatic subjects. The clinical characteristics, including lower gastrointestinal symptoms, and ultrasonographic features of the bowel, including diverticula and thickening of the muscularis propria of the sigmoid colon, were investigated. In addition, the genotype of MFS patients was assessed. The characteristics of patients and controls were compared using parametric tests. Results: Complaints of abdominal symptoms were made by 23 (25.6%) patients with MFS and 48 (53%) control subjects (p < 0.01). Constipation and bloating were reported less frequently by MFS patients than controls (constipation: 13.3% vs. 26.6%, p = 0.039; bloating: 3.3% vs. 41.1%, p < 0.0001), while other symptoms were not significantly different. Sigmoid diverticulosis was detected in 12 (12.3%) patients with MFS, as well as in 3 (3.3%) asymptomatic healthy subjects and 4 (4.4%) random controls (p = 0.0310). The genetic variants of MFS were not correlated with symptoms or diverticula. Conclusion: Patients with MFS have a greater prevalence of diverticula, although less abdominal symptoms, compared to the general population. Symptoms and diverticula in MFS are not correlated with any genetic variant.

Abstract
1: ESGE recommends that each center implements a written policy regarding the management of iatrogenic perforations, including the definition of procedures that carry a higher risk of this complication. This policy should be shared with the radiologists and surgeons at each center. 2 : ESGE recommends that in the case of an endoscopically identified perforation, the endoscopist reports its size and location, with an image, and statement of the endoscopic treatment that has been applied. 3: ESGE recommends that symptoms or signs suggestive of iatrogenic perforation after an endoscopic procedure should be rapidly and carefully evaluated and documented with a computed tomography (CT) scan. 4 : ESGE recommends that endoscopic closure should be considered depending on the type of the iatrogenic perforation, its size, and the endoscopist expertise available at the center. Switch to carbon dioxide (CO2) endoscopic insufflation, diversion of digestive luminal content, and decompression of tension pneumoperitoneum or pneumothorax should also be performed. 5 : ESGE recommends that after endoscopic closure of an iatrogenic perforation, further management should be based on the estimated success of the endoscopic closure and on the general clinical condition of the patient. In the case of no or failed endoscopic closure of an iatrogenic perforation, and in patients whose clinical condition is deteriorating, hospitalization and surgical consultation are recommended.

Endoscopic closure of iatrogenic colon perforation using dual-channel endoscope with an endoloop and clips: methods and feasibility data (with videos). Surg Endosc 2019; 33:1342-1348. [PMID: 30604267 DOI: 10.1007/s00464-018-06616-7] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2018] [Accepted: 12/03/2018] [Indexed: 02/06/2023]
Abstract
BACKGROUND Colon perforation is the most serious complication associated with colonoscopic procedures. We performed a novel purse-string suture technique to close the iatrogenic colonic perforation using dual-channel endoscope with an endoloop and clips. METHODS Iatrogenic colon perforations developed during diagnostic colonoscopy referred to a tertiary hospital over 10 years were considered for this endoscopic closure. An endoloop was inserted through the left channel of the endoscope and placed around the defect. The first clip was placed at the proximal site of the defect through the other channel of the endoscope, and the endoloop was anchored on the mucosa around the defect. Then, subsequent clips were placed next to previous clips and the endoloop was fixed. After the defect was encircled by the endoloop and clips, the rim of the opening was approximated by fastening the endoloop with a purse-string technique. RESULTS A total of 8 patients were admitted to our hospital because of iatrogenic colon perforations during diagnostic colonoscopy. Of these, 2 underwent laparoscopic surgery and 6 underwent endoscopic closure by this novel purse-string suture technique. The estimated diameters of the perforations were 20 mm. All cases were successfully treated in the endoscopy unit without sedation or general anesthesia, and recovered without any complication or subsequent operation. Abdominal pain had nearly resolved within 3 days after the procedure in all patients, and only mild peritonitis was observed. CONCLUSIONS Iatrogenic colon perforation can be treated with a purse-string suture technique using dual-channel endoscope with an endoloop and clips. This technique can be useful for relatively large colon perforations associated with diagnostic colonoscopy.

Abstract
BACKGROUND Transanal irrigation(TAI) has been reported to be an inexpensive and effective treatment for low anterior resection syndrome(LARS). The aim of the present prospective study was to evaluate the use of TAI in patients with significant LARS symptoms at a single medical center. METHODS Patients who had low anterior resection for rectal cancer between April 2015 and May 2016 at the Careggi University Hospital were assessed for LARS using the LARS and the Memorial Sloan-Kettering Cancer Center Bowel Function Instrument (MSKCC BFI) questionnaires 30-40 days after surgery or ileostomy closure (if this was done). Quality of life was evaluated using a visual analog scale and the Short Form-36 Health Survey. All patients with LARS score of 30 or higher were included (early LARS) as were all patients with a LARS score of 30 or higher referred 6 months or longer after surgery performed elsewhere (chronic LARS) in the same study period. Study participants were trained to perform TAI using the Peristeen™ System for 6 months, followed by 3 months of enema therapy following a similar protocol. RESULTS Thirty-three patients were enrolled in the study. Six patients stopped the treatment. The 27 patients (19 early LARS and 8 chronic LARS) who completed the study had a significant decrease in the number of median daily bowel movements [baseline 7 (range 0-14); 6 months 1 (range 0-4); 9 months 4 (range 0-13)]. The median LARS Score fell from 35.1 (range 30-42) (baseline) to 12.2 (range 0-21) after 6 months (p < 0.0001) and then rose to 27 (range 5-39) after 3 months of enema therapy. There was no difference in LARS score decrease at 6 months between the patients with early and chronic LARS (22.5 and 23.9 respectively; p=0.7) and there were no predictors of score decrease. Four components of the SF-36 significantly improved during the TAI period. The MSKCC BFI score significantly improved in several domains. Twenty-three patients (85%) asked to continue the treatment with TAI after the study ended. CONCLUSIONS TAI appears to be an effective treatment for LARS and results in a marked improvement of continence and quality of life. Patients may be assessed and treated for LARS early after surgery since the treatment benefit is similar to that observed in patients with LARS diagnosed 6 months or longer after surgery. The potential rehabilitative role of TAI for LARS is promising and should be further investigated.

Abstract
Pediatric patients with either functional or organic bowel dysfunction may suffer from constipation and fecal incontinence and represent a complex group in whom management is often difficult. Many noninvasive and invasive treatments have been proposed, with variable efficacy and adverse effects. Transanal irrigation (TAI) is now an accepted alternative, in both children and adults, for bowel dysfunction that has not responded to conservative and medical therapies. There is, however, still some uncertainty about the use of TAI in pediatric populations. Hence, a group of specialists from different nations and pediatric disciplines, all with long-standing experience of bowel management in children, performed a literature search and had round table discussions to determine the best-practice use of TAI in the pediatric patient population. Based on these findings, this article provides best-practice recommendations on indications, patient selection, important considerations before treatment, patient and family training, treatment regimens, troubleshooting, and practical aspects of TAI. We conclude that careful patient selection, a tailored approach, directly supervised training, and sustained follow-up are key to optimize outcomes with TAI in children with functional or organic bowel dysfunction.

Abstract
AIM To clarify the current state of practice for colonic diverticular bleeding (CDB) in Japan.
METHODS We conducted multicenter questionnaire surveys of the practice for CDB including clinical settings (8 questions), diagnoses (8 questions), treatments (7 questions), and outcomes (4 questions) in 37 hospitals across Japan. The answers were compared between hospitals with high and low number of inpatient beds to investigate which factor influenced the answers.
RESULTS Endoscopists at all 37 hospitals answered the questions, and the mean number of endoscopists at these hospitals was 12.7. Of all the hospitals, computed tomography was performed before colonoscopy in 67% of the hospitals. The rate of bowel preparation was 46.0%. Early colonoscopy was performed within 24 h in 43.2% of the hospitals. Of the hospitals, 83.8% performed clipping as first-line endoscopic therapy. More than half of the hospitals experienced less than 20% rebleeding events after endoscopic hemostasis. No significant difference was observed in the annual number of patients hospitalized for CDB between high- (≥ 700 beds) and low-volume hospitals. More emergency visits (P = 0.012) and endoscopists (P = 0.015), and less frequent participation of nursing staff in early colonoscopy (P = 0.045) were observed in the high-volume hospitals.
CONCLUSION Some practices unique to Japan were found, such as performing computed tomography before colonoscopy, no bowel preparation, and clipping as first-line therapy. Although, the number of staff differed, the practices for CDB were common irrespective of hospital size.

Abstract
BACKGROUND Surgical repair of endoscopic perforations of the GI tract used to be the standard, but immediate, secure endoscopic closure has become an attractive alternative treatment with the potential to reduce morbidity and mortality. OBJECTIVE We aimed to perform a systematic review of the medical literature on endoscopic closure of acute iatrogenic perforations of the GI tract. DESIGN A systematic review was conducted according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines. SETTING Available medical literature from 1966 through November 2013. PATIENTS Patients with an acute perforation after an endoscopic procedure that was closed endoscopically. INTERVENTIONS Endoscopic closure of an acute perforation of the GI tract. MAIN OUTCOME MEASUREMENTS Clinically successful endoscopic closure. RESULTS In our search, we identified 726 studies, 702 of which had to be excluded. Twenty-four cohort studies (21 retrospective, 3 prospective) were included in the analysis. No randomized trials were identified. Overall, the methodological quality was low. The 24 studies included described 466 acute perforations in which endoscopic closure was attempted. Successful endoscopic closure was achieved in 419 cases (89.9%; 95% CI, 87%-93%). Successful closure was achieved in 90.2% (n = 359; 95% CI, 87%-93%) of cases by using endoclips, in 87.8% (n = 58; 95% CI, 78%-95%) by using the over-the-scope-clip, and in 100% (n = 2) by using a metal stent. LIMITATIONS Low methodological quality of included studies. CONCLUSION This systematic review suggests that endoscopic perforation closure is a safe and effective alternative for surgical intervention in selected cases; however, the overall methodological quality was low. Prospective, true consecutive studies are needed to define the definitive role of endoscopic closure of perforations.

Adverse Events during Bowel Preparation and Colonoscopy in Patients with Acute Lower Gastrointestinal Bleeding Compared with Elective Non-Gastrointestinal Bleeding. PLoS One 2015; 10:e0138000. [PMID: 26368562 PMCID: PMC4569066 DOI: 10.1371/journal.pone.0138000] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2015] [Accepted: 08/24/2015] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND There are limited data on the safety of colonoscopy in patients with lower gastrointestinal bleeding (LGIB). We examined the various adverse events associated with colonoscopy in acute LGIB compared with non-GIB patients. METHODS Emergency hospitalized LGIB patients (n = 161) and age- and gender-matched non-GIB controls (n = 161) were selected. Primary outcomes were any adverse events during preparation and colonoscopy procedure. Secondary outcomes were five bowel preparation-related adverse events--hypotension, systolic blood pressure <100 mmHg, volume overload, vomiting, aspiration pneumonia and loss of consciousness--and four colonoscopy-related adverse events--including hypotension, perforation, cerebrocardiovascular events and sepsis. RESULTS During bowel preparation, 16 (9%) LGIB patients experienced an adverse event. None of the LGIB patients experienced volume overload, aspiration pneumonia or loss of consciousness; however, 12 (7%) had hypotension and 4 (2%) vomited. There were no significant differences in the five bowel preparation-related adverse events between LGIB and non-GIB patients. During colonoscopy, 25 (15%) LGIB patients experienced an adverse event. None LGIB patient had perforation or sepsis; however, 23 (14%) had hypotension and 2 (1%) experienced a cerebrocardiovascular event. There was no significant difference in the four colonoscopy-related adverse events between LGIB and non-GIB patients. In addition, no significant difference in any of the nine adverse events was found among subgroups: patients aged ≥65 years, those with comorbidities, and those with antithrombotic drug use. CONCLUSIONS Adverse events in bowel preparation and colonoscopy among acute LGIB patients were low. No significant difference was found in adverse events between LGIB and non-GIB patients. These adverse events were also low in elderly LGIB patients, as well as in those with co-morbidities and antithrombotic drug use, suggesting that colonoscopy performed during acute LGIB did not increase adverse events.

World J Gastrointest Endosc 2015; 7:1055-1061.

Abstract
Various procedure-related adverse events related to colonoscopic treatment have been reported. Previous studies on the complications of colonoscopic treatment have focused primarily on perforation or bleeding. Coagulation syndrome (CS), which is synonymous with transmural burn syndrome following endoscopic treatment, is another typical adverse event. CS is the result of electrocoagulation injury to the bowel wall that induces a transmural burn and localized peritonitis resulting in serosal inflammation. CS occurs after polypectomy, endoscopic mucosal resection (EMR), and even endoscopic submucosal dissection (ESD). The occurrence of CS after polypectomy or EMR varies according previous reports; most report an occurrence rate around 1%. However, artificial ulcers after ESD are largely theoretical, and CS following ESD was reported in about 9% of cases, which is higher than that for CS after polypectomy or EMR. Most cases of post-polypectomy syndrome (PPS) have an excellent prognosis, and they are managed conservatively with medical therapy. PPS rarely develops into delayed perforation. Delayed perforation is a severe adverse event that often requires emergency surgery. Since few studies have reported on CS and delayed perforation associated with CS, we focused on CS after colonoscopic treatments in this review. Clinicians should consider delayed perforation in CS patients.

Abstract
OBJECTIVE We compared the clinical efficacy of barium therapy and conservative therapy in preventing recurrence in patients with diverticular bleeding. BACKGROUND Previous case reports have indicated that barium impaction therapy provides initial hemostasis for diverticular bleeding and prevention against rebleeding. METHODS After spontaneous cessation of bleeding, patients were randomly assigned to conservative treatment (n = 27) or high-dose barium impaction therapy (n = 27). Patients were followed up for 1 year after enrollment of the last patient. The main outcome measure was rebleeding. RESULTS Median follow-up period was 584.5 days. The probability of rebleeding at 30-day, 180-day, 1-year, and 2-year follow-up in all patients was 3.7%, 14.8%, 28.4%, and 32.7%, respectively. By group, probability at 1 year was 42.5% in the conservative group and 14.8% in the barium group (log-rank test, P = 0.04). After adjustment for a history of hypertension, the hazard ratio of rebleeding in the barium group was 0.34 (95% confidence interval, 0.12-0.98). No complications or laboratory abnormalities due to barium therapy were observed. Compared with the conservative group, the barium group had significantly (P < 0.05) fewer hospitalizations per patient (1.7 vs 1.2), units of blood transfused (1.9 vs 0.7), colonoscopies (1.4 times vs 1.1 times), and hospital stay days (15 days vs 11 days) during the follow-up period. No patients died and none required angiographic or surgical procedures in either group. CONCLUSIONS High-dose barium impaction therapy was effective in the long-term prevention of recurrent bleeding, and reduced the frequency of rehospitalization and need for blood transfusion and colonoscopic examination.

Abstract
Accident related pneumatic colon perforation is difficult to diagnose in children preoperatively as they are anxious to tell the history of trauma. The presence of pneumoperitoneum always leads to exploratory laparotomy. The sudden onset of tension pneumoperitoneum, intraoperative of multiple site colon injury with or without perforation in normal children should suspect the presence of trauma. Creation of ostomy at the site of normal looking colon preferable to colon resection.
Introduction A pneumatic tool or air tool such as blow gun dust cleaner is a tool driven by compressed air and spraying of the perineum can insufflate the colon due to its high pressure and high flow rate. Presentation of case We present a case of 4 year old boy who developed sudden onset of tense abdominal distention and developed peritonitis. Patient’s family initially denied a history of trauma. Radiologic examination showed pneumoperitoneum and colon dilatation. Exploratory laparotomy revealed a tension pneumoperitoneum, bloody ascitic fluid, multiple site of ecchymosis and serosal tear of the colon and a minute perforation of transverse colon. Postoperative reinvestigation revealed that the patient’s perineum was sprayed, using blow gun dust cleaner. Discussion Air from pneumatic tools produces column of air at pressure of 3.5–8.8 kg/cm2 and pressure greater than the resting anal pressure of 0.109 kg/cm2 force air to enter the colon when the perineum is sprayed. Different degree of colon injury results when airflow is greater than 1.46 L/m, and/or intraluminal pressure greater than 0.109 kg/cm2. In most children, initial anxiety to tell the truth result in difficulty to obtain good history. Conclusion Spraying of the perianal with excessive pneumatic force of greater than the resting anal pressure and high air flow rate causes multiple site colon injury and tension pneumoperitoneum due to colon perforation. Parent should be caution in children playing with high pressure pneumatic tool, and the importance of history is emphases for early correct diagnosis.

Abstract
Bleeding is a relatively rare complication occurring mainly after snare polypectomy. The majority of cases can be managed successfully by endoscopic means leaving very few cases which will ultimately need an operation. Colonic perforation, on the other hand is a serious complication that requires intensive and careful management. Prompt recognition of the perforation during the procedure allows, in selected cases, immediate endoscopic closure with an uneventful and full recovery followed by close monitoring and surgical management in case of clinical deterioration. The criteria for the right selection of perforation cases amenable to endoscopic treatment do still need to be confirmed by prospective studies and further experience is required before a standard algorithm on the endoscopic management of perforations is developed.

Abstract
Cecal perforation due to barotrauma is an increasingly recognized complication of colonoscopy when using room air for insufflation. CO2 is increasingly being utilized for insufflation due to more rapid absorption compared to ambient air and results in reduced post-procedural pain and flatulence. Use of CO2 is thought to protect against barotrauma injury, and use of CO2 during endoscopy has not previously been reported to cause barotrauma perforation during colonoscopy. We present a case of cecal perforation secondary to barotrauma during routine screening colonoscopy with CO2.

Abstract
STUDY DESIGN Review article. OBJECTIVES To provide a consensus expert review of the treatment modality for transanal irrigation (TAI). METHODS A consensus group of specialists from a range of nations and disciplines who have experience in prescribing and monitoring patients using TAI worked together assimilating both the emerging literature and rapidly accruing clinical expertise. Consensus was reached by a round table discussion process, with individual members leading the article write-up in the sections where they had particular expertise. RESULTS Detailed trouble-shooting tips and an algorithm of care to assist professionals with patient selection, management and follow-up was developed. CONCLUSION This expert review provides a practical adjunct to training for the emerging therapeutic area of TAI. Careful patient selection, directly supervised training and sustained follow-up are key to optimise outcomes with the technique. Adopting a tailored, stepped approach to care is important in the heterogeneous patient groups to whom TAI may be applied. SPONSORSHIP The review was financially supported by Coloplast A/S.

Abstract
Despite the increasing use of carbon dioxide for endoscopies during the last years, ambient air is still used. The amount of air depends on several factors such as examination time, presumable diameter of the endoscope channel and of course active use of air by the operator. Although endoscopic complications due to ambient air in the gastrointestinal (GI) tract are a rare observation and mostly described in the colon, we report five cases in the upper GI tract due to insufflating large amounts of air through the endoscopes. All 5 patients needed an emergency upper endoscopy for acute presumed upper GI bleeding. In two cases both esophageal variceal bleeding and ulcer bleeding were detected; the fifth case presented with a bleeding due to gastric cancer. Due to insufflation of inadequate amounts of air through the endoscope channel, all patients deteriorated in circulation and ventilation. Two rumenocenteses and consecutively three laparotomies had to be performed in three patients. In the other two, gastroscopies had to be stopped for an emergency computed tomography. All critical incidents were believed to be a consequence of a long-lasting examination with use of too much air. Therefore in emergency situations, endoscopies should be performed with either submersion, low air flow pumps or even better by the use of carbon dioxide.

Abstract
AIM A high diagnostic yield of colonoscopy has been reported in elderly patients, but there is no data on the yearly yield. Our aim was to detect the yearly yield of colonoscopy in elderly patients. METHODS All consecutive endoscopies in the years 1992-2009 were included. Important endoscopic diagnoses were defined as colorectal cancer (CRC), polyps, diverticuli and inflammation. RESULTS In total, 19 569 endoscopies were performed, of which 1706 (8.7%) were in patients age 80 years or older. The number of women was significantly higher (P < 0.001). The percentage of patients who were 80 years or older was higher than in the general population and remained stable during the study period, though there has been a proportional increase of elderly people in the general population. Inconclusive procedures were present in 106 (6.2%) elderly patients compared with 277 (1.6%) patients under 80 years of age (P < 0.001). There were no significant changes in the consecutive years. A procedure revealing no endoscopic diagnosis was observed less often in patients who were 80 years or older (P < 0.001). CRC was diagnosed in 221 (19.6%) older patients. This figure remained more or less constant each year. Polyps were seen in 448 (8.8%) patients 80 years of age or older. The percentage of patients with diverticuli and inflammation was constant. The number of patients 80 years or older with CRC and polyps rose at a lower rate than the number of older people in the general population. CONCLUSION The yield of colonoscopy in patients 80 years or older was high and constant over the years. The number of tumors rose less than expected compared to the increase of elderly in the general population.
