Abstract

Background: Symptomatic gallstones and inflammatory disorder of the gastro duodenum are common causes of upper abdominal pain. It’s a great challenge to differentiate between gastrointestinal symptoms due to gall stones or any other causes. These gastrointestinal symptoms may be related to gallstones but underlying correlation has not been established yet, which is extremely disappointing for the operating surgeon.

Aim: To find out role of preoperative endoscopy in symptomatic gall stones.

Methods: Prospective observational multicentre study of 382 patients undergoing Laparoscopic cholecystectomy from July 2014 to December 2015. All patients diagnosed with gallstones based on ultrasound abdomen, irrespective of age and sex. All patients were subjected to Upper Gastrointestinal Endoscopy 24 to 48 hours before cholecystectomy biopsy were obtained for histopathology if required. Those patients not keen for surgery, pregnant ladies due to risk of foetal loss, CBD stone, obstructive jaundice, carcinoma of gall bladder, was excluded

Results: During this period, 382 patients. The female to male ratio 4.78:1 (316 versus 66), and the mean patient age was 46.10 ± 6.31 years (22 to 65 years). 146 (38.21%) Patients were present with typical pain and 236 (61.78%) atypical pain. Ultrasound revealed single stone in 83 (21.72%), multiple stones in 299 (78.27%), impacted stone at the neck of gallbladder was found in 68 (17.80%) patients, Thick wall gallbladder was seen in 221 (57.85%) patients and contracted gallbladder 44 (11.51%) patients. Pre-operative upper gastrointestinal endoscopy findings revealed Esophagitis in 22 (5.75%) cases, GERD in 26 (6.80%) cases, gastritis in 88 (23.03%), gastric ulcer 49 (12.82%), duodenal ulcer in 39 (10.20%), polyps 21(5.49%) and carcinoma of stomach 9 (2.35%). In all patients with typical pain complete relief of symptoms were observed within 15days post- operatively. Out of 236(61.78%) cases with atypical pain had persistence of symptoms in 141 (59.74%) cases up to four months.

Conclusion: Upper Gastrointestinal Endoscopy should be performed preoperatively for gallstone disease to evaluate atypical symptoms and a patient is fully informed in addition treated for associated conditions.

Introduction

Symptomatic gallstones and inflammatory disorder of the gastro duodenum are common causes of upper abdominal pain. It’s a great challenge to differentiate between gastrointestinal symptoms due to gall stones or any other causes. Distinguishing between these two situations is crucial, because both gallstones and upper GI symptoms are common in the general population, these are not always related and therapeutic strategies may be different regarding to each of them. These gastrointestinal symptoms may be related to gallstones but underlying correlation has not been established yet, which is extremely disappointing for the operating surgeon. While cholecystectomy can be curative in those whose symptoms are related to gallstones, it exposes the rest to unnecessary risk, delays definitive treatment for the actual cause of symptoms, and incurs unnecessary expense. There is a marked geographic variation in gallstone prevalence (Figure 1).

Figure 1: Prevalence.

About 20 million people in the USA (15% of the population) have gallstones [1]. The Third National Health and Nutrition Examination Survey (NHANES III) indicated a higher prevalence in Mexican-Americans than in non-Hispanic whites, and a lower prevalence in non-Hispanic blacks [2]. In Europe, ultrasound studies revealed a prevalence of 9-21% and an incidence of 0.63/100 persons/year [3]. A trend for increasing gallstone prevalence has been identified in Europe and North America by necroptic [4] and ultrasound studies [5,6]. Symptomatic and complicated stones represent only 20% of all gallstones, they lead to clinically relevant morbidity and complications as well as high costs of medical care. Complication rates are higher in older people and in some ethnic groups, and are also influenced by socio-economic factors [7-9]. Nevertheless, given the high proportion of non-specific abdominal symptoms in the people with known cholelithiasis may lead to unjustifiable cholecystectomies [10,11]. Most of the patients presenting to general practitioners with chronic or colicky upper abdominal pain undergo ultrasound examination after ultrasound detection of gallstones the main focus of the attending clinician stays around treating the gallstones and further investigations to rule out other pathologies that may produce similar symptoms are seldom considered [12]. Almost all the patients with proven gallstones are referred to surgeons with a view to performing laparoscopic cholecystectomy [13]. 80% of the referred patients with gallstones presented with other abdominal symptoms [11]. Sometimes, patients have mixture of atypical upper GI symptoms and discovered to have gallstones on imaging studies [14]. The latter group where inappropriate cholecystectomies thus performed are likely to be associated with poor symptomatic outcome [13].

Methods

Prospective observational multicentre study of 382 patients undergoing Laparoscopic cholecystectomy from July 2014 to December 2015. All patients diagnosed with gallstones based on ultrasound abdomen and typical or atypical abdominal pain, irrespective of age and sex. All patients were subjected to Upper Gastrointestinal Endoscopy 24 to 48 hours before cholecystectomy biopsy were obtained for histopathology if required. The OGD examinations were performed by Gastroenterologists and GI surgeons. Where polyps were found, they were removed and assessed histopathologically. Scheduled cholecystectomy was postponed when there were gastric or duodenal ulcers, gastric polyps, or inflammatory changes of gastric mucous membrane until histopathologic results were obtained and ulcers healed. The decision for cholecystectomy was made by the surgeons. The following preoperative parameters were recorded: age, sex, obesity, previous abdominal surgery, presentation with acute cholecystitis, pancreatitis or obstructive jaundice, ultrasonography detection of gallbladder wall thickening or gallbladder stones, and the presence of Common Bile Duct (CBD) stones. Clinical patterns of patient’s pain, endoscopic and pathologic findings as well as related comorbidities were obtained from the patient’s case notes. Endoscopic findings divided the problem into four main groups, normal, inflammation, ulcer, and others (polyps, varices etc.) whilst the pathological findings were defined as benign and malignant. Those patients not keen for surgeries, pregnant ladies due to risk of foetal loss, CBD stone, obstructive jaundice, carcinoma of gall bladder, were excluded.

Statistical analysis

Data were analysed using the Statistical Package for Social Sciences (SPSS, version 17). Mean values were compared using the Student t test. Univariate analysis of categorical variables was performed by the chi-square test.

Results

During this period 382 patients, the female to male ratio 4.78:1 (316 versus 66), and the mean patient age was 46.10 ± 6.31 years (22 to 65 years) (Figure 2 & Table 1). 146 (38.21%) Patients were present with typical pain and 236 (61.78%) atypical pain (Figure 3). Ultrasound revealed single stone in 83 (21.72%), multiple stones in 299 (78.27%), impacted stone at the neck of gallbladder was found in 68 (17.80%) patients, Thick wall gallbladder was seen in 221 (57.85%) patients and contracted gallbladder 44 (11.51%) patients (Figure 4). Pre-operative upper gastrointestinal endoscopy findings revealed Esophagitis in 22 (5.75%) cases, GERD in 26 (6.80%) cases, gastritis in 88 (23.03%), gastric ulcer 49 (12.82%), duodenal ulcer in 39 (10.20%), polyps 21(5.49%) and carcinoma of stomach 9 (2.35%) (Figure 5). In all patients with typical pain complete relief of symptoms were observed within 15 days’ post operatively. Out of 236(61.78%) cases with atypical pain had persistence of symptoms in 141 (59.74%) cases up to four months (Tables 2 & 3) (Figure 6).

Discussion

Gallstone disease is one of the most common and costly of all digestive diseases leading to surgical intervention.It occurs in up to 20% of men and 35% of women in Western societies [15,16]. The most common presentations are biliary colic (56%) and acute cholecystitis (36%) [17]. Other presentations and complications can occur. UK Hospital Episode Statistics’ data for the years 2003-2005 showed that 25,743 patients were admitted as an emergency with acute gallbladder disease during that period [18]. Based on data from Hospital Episode Statistics there were 69,333 cholecystectomies performed in the UK in 2013/14, of these, 64,347 were laparoscopic cholecystectomies. More than 1 in 10 patients (10% - 18%) undergoing cholecystectomy for gallstones have concomitant common bile duct stones, [19] and up to 3.8% have symptoms related to common bile duct stones during the first year after cholecystectomy [20]. 70-85% per cent of people with cholelithiasis are asymptomatic [21] or have nonspecific symptoms such as pain in their abdomen, stomach, back or shoulder, which may be misattributed to other conditions such as dyspepsia or general back ache. In most cases, asymptomatic gallstone is detected incidentally through imaging such as ultrasound or MRI as part of investigations for other conditions. For about 20% of people with cholelithiasis, the condition is symptomatic and can cause the complications (cholecystitis, cholangitis, obstructive jaundice, pancreatitis) that can be extremely painful and, in some cases, life threatening and needing emergency treatment. There is variation within the NHS in how asymptomatic gallbladder stones are managed once they have been diagnosed. Some adults are offered treatment to prevent symptoms and complications developing. Others are offered a watch-and-wait approach, and only have active treatment once the stones begin to cause symptoms. The symptoms of gallstone disease range from mild, nonspecific that can be difficult to diagnose, to severe pain and/or complications which are often easily recognised as gallstone disease by health professionals, mild, nonspecific symptoms of gallstone disease may attribute their symptoms to other conditions, or may be misdiagnosed and undergo unnecessary investigations and treatment as happened in our study in which we found 61.78% patients with atypical symptoms. This has a detrimental effect on quality of life and has an impact on the use of NHS resources. Thus, there is a need to identify whether there are any specific signs, symptoms or risk factors for gallstone disease and to identify the best method for diagnosing the condition so that patients can be managed appropriately. Some people with gallstone disease present with symptoms that can be vague and easily misattributed to other conditions (such as indigestion or general abdominal discomfort), and patients may be investigated or treated for a condition that they do not have. This ultimately affects patient quality of life, and the use of NHS resources as patients will continue to have unresolved symptoms that may get worse, resulting in inappropriate treatments and investigations being offered to the patient. Gallstones found incidentally in the investigation of gastrointestinal symptoms may become falsely incriminated to explain pathology that arises outside the biliary tree [22]. There are wide range of gastrointestinal symptoms have been linked to gallstones but causal relationship has not been established yet [10,14]. Although, gallstone disease is asymptomatic in the clear majority of individuals, it is commonly accepted that removal of the gallbladder is the best treatment for symptomatic gallstone disease [13]. However, less focus has been on patient selection and typical or common symptoms of this disease to understand prevailing symptoms after surgery. Cholecystectomy is a commonly performed abdominal surgical procedure performed for treatment of symptomatic gall stones and prevention of complications. Nevertheless, given the high proportion of non-specific abdominal symptoms in the people with known gallstones may lead to unjustifiable cholecystectomies [10,23]. There are a range of endoscopic, surgical and medical treatments available to treat gallstone disease. Surgery to remove the gallbladder (cholecystectomy) is the most common way to treat biliary pain or cholecystitis caused by gallstones and is one of the most commonly performed surgical procedures in the NHS. An upper GI endoscopy has been recommended in patients with nonspecific upper abdominal pain, history of peptic ulcer disease and persisting pain after laparoscopic cholecystectomy [12]. In our study Pre operative upper gastrointestinal endoscopy findings revealed normal gastroscopy in 34.03% (130 out of 382patients) this is in contrast with other studies. Rassek et al, in his study 589 out of 960 patients underwent gastroscopy for elective cholecystectomy, however 56% had normal gastroscopy, 11.3%(113 patients) underwent a change in plan of therapy because of the OGD findings [24], and recommended that investigation of the upper gastrointestinal tract must precede an elective cholecystectomy. Schenk et al, in his study, 1064/ 1143 (93.1%) patients underwent OGD and 345 patients (30.2%) had pathological findings. Of these, 68.3% were inflammatory in nature 28 patients (2.5%) underwent additional GI surgical procedures along with cholecystectomy and bile duct exploration 19.8% (227 patients) underwent pharmacological treatment of the gastrointestinal disease after their biliary surgery [25], and suggested that owing to the high incidence of concurrent disease in the upper GI tract, preoperative gastroscopy should be performed prior to elective surgical therapy of symptomatic gallstones. Study of Thybusch et al., discuss the value and therapeutic implications of routine OGD before cholecystectomy, in his study 47.3% (160/338) patients undergoing cholecystectomy also had Upper GI endoscopy, amongst those he observed gastritis (25.7%), peptic ulcer disease (6.8%), hiatus hernia (4.7%) polyps (3.2%), oesophagitis (3%), gastric erosions (1.8%) and gastric cancer (.6%). Findings on gastroscopy did not necessarily correlate with clinical symptoms. OGD findings influenced management in 8.3% of patients and the surgery was postponed awaiting medical treatment. Further, two patients with gastric cancer underwent gastrectomy [26].In studies by Faisal et al., [27] and Mozafar et al., [28] found 77.2% and 83% of patients with atypical pain had abnormal OGD fndings. This establishes the importance of UGE prior to elective cholecystectomy especially with atypical pain. In the present study, therapeutic approach was changed in 9 (2.35%) who were diagnosed with malignancy in pathological reports. Prospective design of the present study, it was possible to evaluate the symptoms of the participating patients. A potential weakness of study cost effectiveness of routine OGD for every patient, variation in practice in country (Asia and Europe). In author’s opinion, it would have been necessary to exclude patients with the clear diagnosis of a cholecystitis by ultrasound abdominal. An acute cholecystitis would almost always require surgical treatment, as it explains the symptoms. Higher incidence of concurrent upper gastrointestinal problems in patients with gall stones and atypical abdominal pain OGD before elective cholecystectomy can highly influence the management which in this group can be clinically helpful regarding postoperative outcomes. It would also have been necessary to follow up the patients subsequently.

Conclusion

Upper Gastrointestinal Endoscopy should be performed preoperatively for gallstone disease to evaluate atypical symptoms and patients are fully informed in addition treated for associated conditions.

Outcomes and Safety of Open vs. Laparoscopic Surgery in Patients with Cirrhosis

Background & Aims: The risk of laparoscopic surgery in cirrhotics remains unclear. We report on outcome and safety of open versus laparoscopic surgery in cirrhotics.

Methods: Retrospective review of cirrhotics undergoing abdominal or pelvic surgery at a university hospital from 2000 to 2010. Pre-, intra-, and post-operative data was collected. Open and laparoscopic patients were compared for post-operative outcomes including minor and major complications, hepatic decompensation, and mortality. Patients were stratified by Child-Pugh and MELD scores, and emergent vs. elective surgery. 164 total patients were identified (131 open and 31 laparoscopic).

Results: There was significantly more intra-operative blood loss (p<0.001) and minor complications (p=0.043) in the open group, but no other significant differences between the laparoscopic and open patients. All 5 deaths occurred in open patients (p=0.58). Increasing Child and MELD scores were predictive of adverse events. Overall complications, hepatic decompensation (p=0.015) and death (p<0.022) were more common in open emergent compared to open elective cases. In open emergent Child C patients, 100% had major complications and hepatic decompensation and 67% died. Of emergent open MELD>20 patients, 100% had major complications, 67% had hepatic decompensation, and 33% died.

Conclusion: Open and laparoscopic surgical approaches for cirrhotics yielded similar safety and outcomes. Child and MELD scores were predictive of adverse outcomes. Emergent cases were more likely to have complications than elective cases. Further studies including larger numbers of emergent laparoscopic patients are needed to better ascertain the risk of laparoscopy in cirrhotics.

Case Series and a Review of Cannabinoid Hyperemesis Syndrome

Cannabinoid hyperemesis syndrome (CHS) is a condition observed in patients with chronic use of cannabis. It is characterized with GI symptoms including nausea, vomiting, abdominal pain and diarrhea. The patients tend to be chronic abusers for several years and experience these symptoms in a cyclical manner similar to the cyclical vomiting syndrome. They find relief after taking hot baths, a pathognomonic feature of CHS. We hereby describe 3 cases who presented with clinical features consistent with CHS. Cannabis acts through CB1 and CB2 receptors located in brain and gastrointestinal tract, respectively. There are no standard therapeutic measures available for management of CHS. We propose the idea of using short-acting cannabinoids including dronabinol. Also review of literature suggests treatments with drugs including clonidine, lorazepam and risperidone. Recent endeavors on legalization of recreational cannabis use have initiated several debates and we should be mindful of CHS as one of its long-term complications.

Pharmacological Characterization of Muscarinic Receptor Subtypes Involved in Carbachol-Induced Contraction of the Chicken Proventriculus

Present study was designed to characterize the postjunctional muscarinic acetylcholine receptor mediating contraction of the chicken proventriculus by using muscarinic receptor agonists and antagonists. Muscarinic agonists caused concentration-dependent contraction. The ranking order of pEC50 values were muscarine > arecaidine propargyl ester > oxotremorine M > carbachol > methacholine > arecoline > acetylcholine > bethanechol = McN-A343 = pilocarpine. The responses to carbachol were competitively antagonized by AF-DX116 (pKb =5.9), AF-DX384 (6.84), 4-DAMP (8.79), methoctramine (5.81), pirenzepine (6.78), p-F-HHSID (7.41), atropine (8.43),tropicamide (6.91), himbacine (7.01), AQ-RA741 (6.6) and dimethindene (6.73). The correlation of pKb of the chicken proventriculus with that of the mammalian M3 receptor was the highest among five muscarinic receptors. The proventriculus membrane contained a single class of [3 H]-quinuclidinyl benzilate binding sites. pKi values of the antagonists in a binding displacement study correlated with that of the M3 subtype. Pertussis toxin(100µg/kg, i.p. for 72h) significantly decreased the contraction induced by a low concentration of carbachol. In 4-DAMP mustard and AF-DX116-pretreated muscle strips, AF-DX116 shifted the concentration-response curve for oxotremorine M to the right in the presence of 5-hydroxytryptamine and forskolin. The pKb value (6.22) was significantly higher than that obtained in the normal condition (5.78). Isoproterenol increased cyclic AMP, and carbachol significantly decreased the isoproterenol-induced increase in cyclic AMP. The results indicated that a muscarinic agonist mainly acts on the M3 receptor to cause contraction of the chicken proventriculus but the possible involvement of M2 /M4 receptors cannot be excluded as demonstrated in mammalian gastrointestinal tract.

A Case Report on Ulcerative Colitis with Interventional Outcomes

Ulcerative Colitis (UC) is a mucosal disease that usually involves the rectum and extends proximally to involve all or part of the colon. Main causes are gut microbiota, dysregulation of the host’s immune system, genetic susceptibility and environmental factors. Active disease can be associated with a rise in acute phase reactants [C - reactive protein (CRP)], platelet count and Erythrocyte Sedimentation Rate (ESR) and a decrease in hemoglobin. Colonoscopy is used to assess disease activity and is often performed before treatment. In this case, recurrence UC was observed and it was treated with suitable therapy but some drug interactions like metronidizole additive effect with ofloxacin results in ST-T elevation and adverse effects like abdominal pain, burning pain in midsternal area radiating to epigastric region [Calcium+Vitamin-D] were seen. Those are monitored by the alternative therapy like dose management and drug alterations.

Prediction and Diagnosis of Fatty Liver in Dairy Cows

Fatty liver is defined as an accumulation of fat, mainly Triacylglycerol (TAG) in liver. Fatty liver in dairy cows is categorized into mild, moderate and severe fatty liver. Obesity in pregnant cow is crucial etiological factor for postpartal development of fatty liver. Namely, obese cows have a greater decrease in feed intake during the period around parturition and, therefore, have a more severe negative energy balance during early lactation which leads to increased lipolysis of adipose tissue. Non Esterified Fatty Acids (NEFA), released from the stored TAG in the adipose tissue, are readily taken up by liver. The excess of NEFA may be converted to TAG and deposit in liver. Liver biopsy is the only reliable method for the detection of fatty liver, especially for the determination of its severity through the estimation of total lipids and TAG. Ecography may be considered as noninvasive, on-farm method for diagnosis of fatty liver which is not commonly used do to the not widely achievable equipment. Since some metabolic and endocrine parameters are significantly correlated with fatty liver degree, they may be used as diagnostic indicators of fatty liver. The significance of those indicators for diagnosis of fatty liver is present in this review. Additionally, indicators that may be used for prediction of fatty liver are explained. Specially attention was given to glucose, NEFA, BHBA, liver enzymes, total bilirubin, total protein, albumin and urea as well as some hormones involved in lipid metabolism. Achievements of novel methods, like genomic and proteomic profiling of biological fluids of diseased cows, in providing tools for diagnosis and prognosis of this metabolic disease are presented.

Primary Gastric Lymphoma

The treatment of primary gastric lymphoma is evolving in post-rituximab era. The role of Helicobacter pyroli eradication alone can cure not only Mucosa-Associated Lymphoepithelial Tumor (MALT) but also some of diffuse large B cell lymphoma with or without MALT component. The efficacy of rituximab containing chemotherapy is so effective that the role of surgery is overshadowed. There are many studies, although most of them were retrospective trials, however it highlights the current mainstay of immune-chemotherapy provided an outstanding long term survival more than 80-90%.H pylori In real world there are substantial patients may receive surgery first, yet still needs post-operative adjuvant chemotherapy for some of them has a risk of relapse of lymphoma. And recent studies showed there’s no statistical difference between the two modalities. The main reason for patients proceeded to surgery as primary treatment is the gastroenterologist preference and showed no difference in terms of progression free survival and overall survival. The rituximab was introduced to lymphoma treatment since 1999, and demonstrated a superior long term survival in diffuse large B cell lymphoma for R-CHOP relatively to CHOP regimen. The highly effective treatment made PGL being easily curable disease; furthermore there are new insights of why and how the antibiotic therapy as exclusive treatment for limited disease will be a mainstay in treating this malignancy. We make a proposal how to treat the primary gastric lymphoma and MALT, and highlight the changing treatment modalities with regards to the integration of Helicobacter pyroli eradication to conventional chemotherapy as well as the complimentary role of surgery and radiotherapy.

Bleeding Peptic Ulcer: Epidemiology, Treatment and Prognosis

Aims: The aim of this study was to demonstrate epidemiological, clinical and endoscopic characteristics of acute Upper Gi Bleeding (UGIB) with a focus on Peptic Ulcer Bleeding (PUB).

Methods: This study included 2198 consecutive patients that were referred to our emergency department due to acute Upper Gi Bleeding (UGIB) from January 2008 to December 2012. All patients under went urgent upper GI endoscopies within 24 hours of admission, and 842 patients diagnosed with PUB were enrolled and prospectively followed.

Results: The cumulative incidence of UIGB was 126/100000 for a 5-year period. Two out of five patients had a bleeding peptic ulcer, of which 440 (52.3%) patients had a bleeding gastric ulcer, 356 (42.3%) had a bleeding duodenal ulcer, 17 (2%) had both bleeding gastric and duodenal ulcers and 29 (3.5%) patients had bleeding ulcers on gastroenteric anastomosis. PUB was more common in men. Average patient age was 65.9 years. The majority of patients with PUB were taking agents that attenuate the cytoprotective function of the gastric and duodenal mucosa (57%).Half of the patients received a red blood cell transfusion, with a median of 2.2 units. Re-bleeding occurred in 77(9.7%) patients and 47 (5.9%) required surgical intervention. The thirty-day morality was 5.2%, and 10% of patients died from uncontrolled bleeding and concomitant diseases.

Conclusion: PUB is the main cause of UGIB, characterized by a significant re-bleeding rate and mortality.

An Update on Hepatorenal Syndrome

The Hepatorenal Syndrome (HRS) is one of many potential causes of Acute Kidney Injury (AKI) in patients with decompensated liver disease.

HRS is associated with poor prognosis and represents the end-stage of a sequence of reductions in renal perfusion induced by progressively severe hepatic injury.

The pathophysiology of HRS is complex with multiple mechanisms interacting simultaneously, although HRS is primarily characterised by renal vasoconstriction.

A recently revised diagnostic criteria and management algorithm for AKI has been developed for patients with cirrhosis, allowing physicians to commence treatment promptly.

Vasopressor therapy and other general management, such as antibiotic prophylaxis, need to be initiated while patients are assessed for eligibility for transplantation. Liver transplantation remains the treatment of choice for HRS but is limited by organ shortage.

Other management options, such as transjugular intrahepatic portosystemic shunt, renal replacement therapy and molecular absorbent recirculating system, may provide short term benefit for patients not responding medical therapy while awaiting transplantation.

Clinicians need to be aware of the pathophysiology and management principles of HRS to provide quality care for patients with multi-organ failure.

Abdominal CT Findings of Cholecystogastric Fistula

Enteric fistulas are abnormal connections between the gastrointestinal tract and other organs, chest or skin. Fistulas between the gall bladder and the gastrointestinal system are common [1]. Cholecystoduodenal and cholecystocolic fistulas are seen frequently while cholecystogstric ones are rare [2]. In our case, we accidentally discovered a cholecystogastric fistula in a 71 years old male patient with gastric adenocarcinoma in orally and intravenous contrast enhanced abdomen CT.

Post-Colonoscopy Colorectal Carcinomas (PostCRCs): Have we Improved Over Time?

Background and Aim: There is an increasing concern on Post-Colonoscopy Colorectal Carcinomas (PostCRCs). Little is known about how these figures have evolved over time. We aim to compare the rates of PostCRCs in two periods of time and identify the risk factors.

Methods: Retrospective control-case study in our Endoscopic Unit. We studied two separate intervals (March 2004-September 2011 and October 2011 - December 2016). In both periods of time all patients diagnosed with CRC were identified. Patients with a previous colonoscopy performed 12 to 60 months before were retrieved (cases) and compared with those who did not have a previous procedure (controls).

Results: 712 and 743 patients diagnosed with CRC in both periods of time. 24 patients in the first period (3.6%) and 28 patients in the second one (3.8%) had a previous colonoscopy performed. PostCRCs were mainly located on the right side of the colon (63% vs. 35% p=0.006 and 68% vs. 33% p< 0.001), were smaller in size (3.17 vs.4.46 p< 0.001 and 3.61 vs. 4.44 p=0.086), with a tendency to host a better TNM stage. No differences in sex and age were found.

More than half of PostCRCs (58.3% and 60.7%) were attributed to procedure causes, meanwhile10 PostCRCs in both periods were considered new developed CRCs.

Conclusions: Despite what could be expected, we did not find a decrease in the rate of PostCRCs over time. A combination of preventable as much as biological factors would account for their etiology.
