Abstract
BACKGROUND AND AIMS Women with Lynch Syndrome (LS) have a high risk of colorectal and endometrial cancer. They are recommended regular colonoscopies, and some choose prophylactic hysterectomy. The aim of this study was to determine the impact of hysterectomy on subsequent colonoscopy in these women. MATERIALS AND METHODS A total of 219 LS women >30 years of age registered in the clinical registry at Section for Hereditary Cancer, Oslo University Hospital, were included. Data included hysterectomy status, other abdominal surgeries, and time of surgery. For colonoscopies, data were collected on cecal intubation rate, challenges, and level of pain. Observations in women with and without hysterectomy, and pre- and post-hysterectomy were compared. RESULTS Cecal intubation rate was lower in women with hysterectomy than in those without (119/126 = 94.4% vs 88/88 = 100%, p = 0.025). Multivariate regression analysis showed an increased risk of challenging colonoscopies (OR,3.58; CI: 1.52-8.43; p = 0.003), and indicated a higher risk of painful colonoscopy (OR, 3.00; 95%CI: 0.99-17.44, p = 0.052), in women with hysterectomy compared with no hysterectomy. Comparing colonoscopy before and after hysterectomy, we also found higher rates of reported challenging colonoscopies post-hysterectomy (6/69 = 8.7% vs 23/69 = 33.3%, p < 0.001). CONCLUSIONS Women with hysterectomy had a lower cecal intubation rate and a higher number of reported challenging colonoscopy than women with no hysterectomy. However, completion rate in the hysterectomy group was still as high as 94.4%. Thus, LS women who consider hysterectomy should not be advised against it.

Abstract
Colonoscopy is the gold standard for colon cancer screening. It has led to a decrease in the incidence of colorectal cancer mortality. Colon perforation is a feared complication of this procedure with high morbidity and substantial mortality. Due to the high volume of colonoscopies performed, the absolute number of colonoscopic perforations is relatively high. It leads to a substantial cost to the patient and the health system. Understanding the mechanisms and the risk factors may help in preventing perforation. Traditionally, a laparotomy with creation of a stoma was used to address this complication. However, minimally invasive techniques such as laparoscopy and endoluminal repairs are being used more commonly now. More surgeons are favoring primary anastomosis (with or without a diverting loop ileostomy) than a Hartmann procedure.

J Gastric Cancer 2016; 16:167-176. [PMID: 27752394 PMCID: PMC5065946 DOI: 10.5230/jgc.2016.16.3.167] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/27/2016] [Revised: 08/22/2016] [Accepted: 09/04/2016] [Indexed: 01/09/2023] Open
Abstract
Purpose The purpose of this study was to determine the effect of a prior gastrectomy on the difficulty of subsequent colonoscopy, and to identify the surgical factors related to difficult colonoscopies. Materials and Methods Patients with a prior gastrectomy who had undergone a colonoscopy between 2011 and 2014 (n=482) were matched (1:6) to patients with no history of gastrectomy (n=2,892). Cecal insertion time, intubation failure, and bowel clearance score were compared between the gastrectomy and control groups, as was a newly generated comprehensive parameter for a difficult/incomplete colonoscopy (cecal intubation failure, cecal insertion time >12.9 minutes, or very poor bowel preparation scale). Surgical factors including surgical approach, extent of gastrectomy, extent of lymph node dissection, and reconstruction type, were analyzed to identify risk factors for colonoscopy performance. Results A history of gastrectomy was associated with prolonged cecal insertion time (8.7±6.4 vs. 9.7±6.5 minutes; P=0.002), an increased intubation failure rate (0.1% vs. 1.9%; P<0.001), and a poor bowel preparation rate (24.7 vs. 29.0; P=0.047). Age and total gastrectomy (vs. partial gastrectomy) were found to be independent risk factors for increased insertion time, which slowly increased throughout the postoperative duration (0.35 min/yr). Total gastrectomy was the only independent risk factor for the comprehensive parameter of difficult/incomplete colonoscopy. Conclusions History of gastrectomy is related to difficult/incomplete colonoscopy performance, especially in cases of total gastrectomy. In any case, it may be that a pre-operative colonoscopy is desirable in selected patients scheduled for gastrectomy; however, it should be performed by an expert endoscopist each time.

Abstract
OBJECTIVES Assess differences in three-dimensional colonic metrics on CTC in women with or without hysterectomy following incomplete endoscopy to determine if there is a correlation between colonic morphology and incomplete colonoscopy after hysterectomy. METHODS Quantitative rectosigmoid metrics were derived from CTC datasets of 37 women with hysterectomy and 36 women without hysterectomy who underwent CTC for incomplete endoscopy. Evaluated metrics included colonic length, volume, tortuosity, and compactness and sigmoid apex height relative to the lumbosacral junction. Differences were measured using the Student's t test, and intra-reader reliability was assessed using ICC. The relative risk of incomplete rectosigmoid visualization was determined by reviewing the endoscopy reports. RESULTS Women with hysterectomy had a lower sigmoid apex height (p = 0.002), as well as increased tortuosity (p = 0.012) and compactness (p = 0.001) and decreased length (p = 0.026) and volume (p = 0.016) of the rectosigmoid. Intra-reader reliability was high for centerline length (ICC = 0.9940) and sigmoid apex height (ICC = 0.9851). The relative risk of incomplete visualization of the rectosigmoid on endoscopy in women with hysterectomy was 2.068 (p = 0.043) compared to women without hysterectomy. CONCLUSION Our pilot data show reproducible quantitative differences in three-dimensional metrics of the rectosigmoid in women with or without hysterectomy who underwent CTC for incomplete endoscopy and increased relative risk of incomplete endoscopic visualization of the rectosigmoid after hysterectomy. Our findings suggest that women with hysterectomy may benefit from CTC rather than endoscopy as the initial diagnostic test for evaluating the colon.

Abstract
Colorectal cancer (CRC) is one of the leading cancers and cause of cancer deaths in American women and men. Females and males share a similar lifetime cumulative risk of CRC however, substantial differences in risk factors, tumor biology, and effectiveness of cancer prevention services have been observed between them. This review distills the evidence documenting the unique variation observed between the genders relating to CRC risk factors, screening and prevention. Consistent evidence throughout the world demonstrates that women reach equivalent levels of adenomas and CRC as men but it occurs nearly a decade later in life than in their male counterparts. Women have a higher proportion of tumors which are hypermethylated, have microsatellite instability and located in the proximal colon suggesting the serrated pathway may be of greater consequence in them than in men. Other CRC risk factors such as smoking, diet and obesity have been shown to have disparate effects on women which may related to interactions between estrogen exposure, body fat distribution, and the biologic underpinnings of their tumors. There is data showing the uptake, choice, and efficacy of different CRC screening methods in women is dissimilar to that in men. The mortality benefit from FOBT, sigmoidoscopy, and protection from interval CRC by colonoscopy appears to be lower in women than men. A greater understanding of these gender idiosyncrasies will facilitate an personalized approach to CRC prevention and should ultimately lead to a reduced burden of disease.

Abstract
BACKGROUND The primary aim of colonoscopy is a complete and thorough examination of the colon. There are a number of factors, however, that can potentially increase the difficulty of completing a colonoscopy. A significant proportion of women eligible for colorectal cancer screening have undergone hysterectomy. A history of hysterectomy is frequently considered to make colonoscopy more difficult, although there is no consensus in the literature. OBJECTIVE The aim of this study is to assess the effect of hysterectomy on colonoscopy completion. DATA SOURCES A systematic search of PubMed, Embase, and the Cochrane database identified 6 eligible studies. STUDY SELECTION Studies that compared colonoscopy completion rates in women with a previous history of hysterectomy and women with no history of pelvic surgery were selected for review. INTERVENTION Meta-analysis was performed by using random-effects methods. MAIN OUTCOME MEASURES The primary outcome used was colonoscopy completion rate. The outcomes were calculated as odds ratio with 95% CI. RESULTS A total of 5947 patients were included in the final analysis. The average hysterectomy rate was 26.3% ± 14.5%. The colonoscopy completion rate was significantly reduced in patients with a history of hysterectomy compared with those with no history of pelvic surgery (87.1% vs 95.5%) (OR, 0.28; 95% CI, 0.16-0.49; p < 0.001). Analysis of the funnel plot demonstrated nonsignificant across-study publication bias. There was significant across-study heterogeneity (Cochran Q, 19.6; p = 0.002). LIMITATIONS The endoscopist's experience is poorly defined in some studies. Indication for colonoscopy was not provided in all cases. There is significant across-study heterogeneity. CONCLUSION Colonoscopy completion rates appear decreased in women with a history of hysterectomy, but the available literature is heterogenous. Further studies in this area are warranted.

Abstract
BACKGROUND AND STUDY AIMS In many Dutch hospitals, open access referral for colonoscopy is authorized by a gastroenterologist after screening a standard referral letter (SRL) without face-to-face contact with the patient. We investigated the added value of a 7.5 min outpatient consultation with a gastroenterologist (OC), regarding the patient indications, priority for colonoscopy, and the frequency of correct information about patient medications and comorbidities on SRLs. PATIENTS AND METHODS In a prospective, blinded, single-center study, gastroenterologists assessed SRLs for the accuracy and priority of the colonoscopy request (SRL). These data were compared to results from the OC, and primary outcomes were the number of patients who were not recommended for colonoscopy and priority scheduling of colonoscopy for suspicion of cancer. RESULTS Patients were analyzed using both SRL and OC and, of 255 patients, 224 of them underwent colonoscopy. Colonoscopy was not recommended for 6.3 % and 11.4 % of patients using the SRL and OC, respectively (P = 0.02). Using the SRL, gastroenterologists did not recommend colonoscopy for seven patients, but the same patients were recommended for colonoscopy when OC was available. This was explained because the indications on the SRL did not match the information obtained from OC. Compared to OC , more colonoscopies were prioritized when the SRL was used to make decisions. Cancer was detected in 7/112 (SRL ) versus 7/65 (OC ) of priority-scheduled patients. SRLs did not report the use of coumarins and insulin in 1.6 % of patients or the prevalence of serious comorbid conditions in 52 % of patients. CONCLUSIONS A 7.5 min outpatient consultation with a gastroenterologist improved the identification of indications for colonoscopy, decreased priority scheduling of patients, and increased the number of patients diagnosed with cancer in the prioritized group. SRLs frequently omitted patients' medications and comorbidities.

Abstract
BACKGROUND The caecal intubation rate (CIR) is an important quality standard for endoscopists, as well as for national bowel cancer screening programmes; however, individuals undergoing colonoscopy for bowel screening and symptomatic patients represent different groups, and their characteristics may affect colonoscopy performance. OBJECTIVE To compare colonoscopists' performance, as assessed by the CIR, in symptomatic patients compared to individuals undergoing colonoscopy for bowel cancer screening. METHODS Retrospective audit of CIRs for all patients undergoing colonoscopy at our institution during the year 2008. We retrieved the data from an endoscopy reporting software database and from the local bowel cancer screening programme database. Demographic data was extracted, as well as details of known factors that may affect completion of colonoscopy, such as poor bowel preparation, presence of diverticular disease, polyps, tumour and strictures. The unadjusted CIRs for colonoscopists participating in the screening programme were compared between the bowel screening and the symptomatic patient groups. RESULTS Five screening colonoscopists performed 1056 colonoscopies, of which 488 were bowel screening procedures. The overall CIR was significantly lower in the symptomatic, compared to the screening, individuals (88.5% versus 93%, P < 0.02). No significant differences were observed between the two groups for risk factors that could impair the CIR. The CIR was <90% for two of the five colonoscopists in symptomatic patients, and just under 90% for one colonoscopist in screening individuals. Multivariate analysis revealed that non-screening colonoscopy was an independent predictor for an incomplete procedure (OR 1.8; 95% CI 1.2-2.8). CONCLUSIONS The CIR, a key quality performance indicator for colonoscopy, is lower in symptomatic patients compared to individuals undergoing colorectal cancer screening. These results suggested that CIR should be monitored independently in screening and non-screening colonoscopies.

Abstract
PURPOSE Colonoscopy efficacy at preventing proximal colorectal cancer (CRC) is questioned, and little is known about efficacy in high-risk versus medium-risk populations. We investigated the relationship between colonoscopy screening, family history of colorectal cancer (FHCC), and CRC risk by site. METHODS Among 92,078 women of the E3N prospective cohort, 692 CRCs have been diagnosed after a median follow-up of 15.4 years. Cox proportional hazard models estimated adjusted hazards ratios according to subsites of cancer and FHCC. RESULTS A personal history of colonoscopy (PHC; n = 37,470) was associated with decreased rectal and distal colon cancer risks (hazard ratio (HR) = 0.57; 95% Confidence Interval (CI) = 0.42-0.78 and HR = 0.37; 95% CI = 0.26-0.52, respectively), but not proximal colon cancer risk (HR = 0.87; 95% CI = 0.64-1.18). In women with no prior colonoscopy, those with FHCC had a 80% higher CRC risk than those without FHCC. In women with previous colonoscopy, CRC risk was similar in women with and without FHCC (p for interaction = 0.04). CONCLUSIONS Results showed colonoscopy ability to prevent distal cancers, but not proximal cancers in women. Colonoscopy screening also reduced the excess risk of women with FHCC to that of women with no FHCC.

Abstract
BACKGROUND There is more to a high-quality colonoscopy than reaching the cecum or finding adenomas. Gentle insertion involves ancillary techniques, some of which are impossible in patients receiving deep sedation. The aim of this study was to assess the importance of ancillary techniques in achieving a comfortable, complete colonoscopy. METHODS This was a prospective study of 500 consecutive outpatient colonoscopies performed by a single endoscopist. During the procedure, note was taken of various ancillary techniques used to facilitate insertion: turning the patient, patient holding their breath, abdominal pressure. The success of these techniques in helping scope advancement was also noted. After the procedure the patient was asked to rate the severity of their pain and their degree of satisfaction with the examination. RESULTS A total of 238 women and 262 men participated in the study, and colonoscopy was complete in 96.2 and 98.5%, respectively. Overall, 97% of patients received versed alone (average dose 2 mg), and 3% received a narcotic (average dose 46 U). Average pain score was 3.9 on a scale of 1 (least pain) to 10 (worst pain), and average satisfaction with the procedure as a whole was 9.5 on a similar scale. Ancillary techniques of holding breath, directed abdominal pressure, and turning to the left, right, and prone were used in 46, 56, 17, 23, and 4% of examinations, respectively. Each technique was effective in helping insertion in over 70% of cases. Turning the patient was also used to clear stool, open the colon, or facilitate polypectomy in another 33 cases. Multiple techniques were used in 49% of patients. CONCLUSION The use of ancillary techniques to facilitate colonoscope insertion helps avoid the expense and potential side effects of deep sedation.

Abstract
INTRODUCTION When severe chronic pelvic pain, constipation, and bloating are due to dense pelvic adhesions fixing the sigmoid loops, patients may be offered the option of sigmoid colectomy. This study examines the effectiveness of colectomy in the treatment of such patients. METHODS Patients were identified from a surgical database, demographic data were abstracted, and charts were reviewed. Patients were interviewed postoperatively. Primary end points were morbidity, length of stay, change in bowel habit, and patient satisfaction. RESULTS There were 46 patients (44 women) with a mean age of 54.7 years (±14.3). Forty-three had a history of prior pelvic surgery (93%), including 30 (65%) with hysterectomy. One quarter had been diagnosed with irritable bowel syndrome. Surgery revealed adhesive tethering of the sigmoid colon in 43 patients (94%). Mean length of stay was 6.5 days (±2.5), and complications occurred in eight (17.3%) patients. There were no deaths, and no patients required a stoma. Follow-up in 37 patients after mean of 7.2(±5.0) years showed significant reductions in abdominal pain and bloating postoperatively, with normalization of bowel function and increase in quality of life. CONCLUSION When severe lower abdominal pain and bloating in women who have had pelvic surgery are reproduced by colonoscopy, and there is an obvious kink in the bowel, sigmoid colectomy is worth considering.

Abstract
Colonoscopy is a relatively invasive modality for the diagnosis and treatment of colorectal disease and for the prevention or early detection of colorectal neoplasia. Millions of colonoscopies are performed each year in the United States by endoscopists with varying levels of skill in colons that present varying levels of challenge. Although better scope technology has made colonoscopy gentler and more accurate, the sheer number of examinations performed means that complications inevitably occur. This article considers the most common complications of colonoscopy, and advises how to minimize their incidence and how to treat them if they do occur.

Abstract
Studies have shown that colorectal cancer (CRC) incidence is equal between men and women. However, several studies have demonstrated lower adenoma detection rates in women than in men. Many questions arise about differences in adenomas, CRC, and screening practices between men and women: should screening be the same for both sexes, are there differences in risk factors in the formation of colon cancer, should special groups of women be screened differently from the general population, are colonoscopies tolerated differently in women and why, and what determines if a woman will undergo colonoscopy? This article reviews these issues.
