Surg Case Rep 2023; 9:172. [PMID: 37773306 PMCID: PMC10541374 DOI: 10.1186/s40792-023-01747-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2023] [Accepted: 09/01/2023] [Indexed: 10/01/2023] Open
Abstract
BACKGROUND Postoperative recurrence is frequently encountered in the management of patients with Crohn's disease and is most often found at the anastomotic site. A novel technique, the Sasaki-W anastomosis, is an antimesenteric cutback end-to-end isoperistaltic anastomosis. We report a patient with Crohn's disease who underwent partial intestinal resection for postoperative anastomotic stenosis, reconstructed with the Sasaki-W anastomosis, after initial intestinal resection reconstructed with a Kono-S anastomosis. CASE PRESENTATION A 30-year-old male was diagnosed with Crohn's disease and treated with mesalamine and adalimumab, and he underwent ileocecal resection using the Kono-S anastomosis at the time of diagnosis. He was treated with infliximab without any symptoms or recurrence for 7 years. He was admitted presenting with upper abdominal pain. Physical examination showed mild tenderness and distension in the upper abdomen. Laboratory data showed no remarkable findings. Computed tomography scan showed wall thickening in the ileum with proximal dilation and fluid retention. Non-operative management with antibiotics and fasting did not improve the symptoms within 7 days. Ten days after admission, ileocecal resection reconstructed with the Sasaki-W anastomosis was performed. At operation, there was a 15-cm intestinal stenosis at the site of the previous Kono-S anastomosis. The transverse colon and ileum were reconstructed with the Sasaki-W anastomosis. The postoperative course was uneventful, and the patient was discharged 17 days postoperatively. The patient had no obstructive symptoms and no findings consistent with bowel obstruction were observed on computed tomography scan one year postoperatively. CONCLUSIONS The Sasaki-W anastomosis is a viable option for intestinal reconstruction in patients with postoperative recurrence after a Kono-S anastomosis.

Abstract
Inflammatory bowel diseases are considered immune disorders with a complex genetic architecture involving constantly changing endogenous and exogenous factors. The rapid evolution of genomic technologies and the emergence of newly discovered molecular actors are compelling the research community to reevaluate the knowledge and molecular processes. The human intestinal tract contains intestinal human microbiota consisting of commensal, pathogenic, and symbiotic strains leading to immune responses that can contribute and lead to both systemic and intestinal disorders including IBD. In this review, we attempted to highlight some updates of the new IBD features related to genomics, microbiota, new emerging therapies and some major established IBD risk factors.

Abstract
IMPORTANCE Crohn disease, a chronic gastrointestinal inflammatory disease, is increasing in incidence and prevalence in many parts of the world. Uncontrolled inflammation leads to long-term complications, including fibrotic strictures, enteric fistulae, and intestinal neoplasia. Therefore, early and effective control of inflammation is of critical importance. OBSERVATIONS The optimal management approach for Crohn disease incorporates patient risk stratification, patient preference, and clinical factors in therapeutic decision-making. First-line therapy generally consists of steroids for rapid palliation of symptoms during initiation of anti-tumor necrosis factor α therapy. Other treatments may include monoclonal antibodies to IL-12/23 or integrin α4β7, immunomodulators, combination therapies, or surgery. Effective control of inflammation reduces the risk of penetrating complications (such as intra-abdominal abscesses and fistulae), although more than half of patients will develop complications that require surgery. Adverse reactions to therapy include antibody formation and infusion reactions, infections, and cancers associated with immune modulators and biologics and toxicity to the bone marrow and the liver. Both Crohn disease and corticosteroid use are associated with osteoporosis. Vaccinations to prevent infections, such as influenza, pneumonia, and herpes zoster, are important components of health maintenance for patients with Crohn disease, although live vaccines are contraindicated for patients receiving immune suppression therapy. CONCLUSIONS AND RELEVANCE The treatment of patients with Crohn disease depends on disease severity, patient risk stratification, patient preference, and clinical factors, including age of onset and penetrating complications, and includes treatment with steroids, monoclonal antibody therapies, immunomodulators, and surgery. Physicians should be familiar with the advantages and disadvantages of each therapy to best counsel their patients.

Abstract
Management of inflammatory bowel disease has evolved extensively in the last three decades. We have learnt a lot about the pathophysiology and natural history of the disease. New effective classes of drugs with the associated potential morbidity have been introduced. New surgical techniques have been popularized leading to a better understanding of the optimal timing of surgery. The result is a very complex subspecialty of gastroenterology and colorectal surgery called the "IBDologist." Only if we manage these complex patients in the context of a multi-disciplinary team will we be able to obtain outstanding outcomes, specifically with high and sustained remission rates for these patients.

Abstract
Acetylcholine (ACh) is best known as a neurotransmitter and was the first such molecule identified. ACh signalling in the neuronal cholinergic system has long been known to regulate numerous biological processes (reviewed by Beckmann and Lips). In actuality, ACh is a ubiquitous signalling molecule that is produced by numerous non-neuronal cell types and even by some single-celled organisms. Within multicellular organisms, a non-neuronal cholinergic system that includes the immune system functions in parallel with the neuronal cholinergic system. Several immune cell types both respond to ACh signals and can directly produce ACh. Recent work from our laboratory has demonstrated that the capacity to produce ACh is an intrinsic property of T cells responding to viral infection, and that this ability to produce ACh is dependent upon IL-21 signalling to the T cells. Furthermore, during infection this immune-derived ACh is necessary for the T cells to migrate into infected tissues. In this review, we will discuss the various sources of ACh that are relevant during immune responses and describe how ACh acts on immune cells to influence their functions. We will also address the clinical implications of this fascinating aspect of immunity, focusing on ACh's role in the migration of T cells during infection and cancer.

Abstract
BACKGROUND This study aimed to identify factors that affect the prognosis of budesonide therapy for Crohn's disease patients. METHOD Change in Crohn's disease activity index (CDAI) scores at latest follow-up after budesonide therapy reported by individual studies were pooled to gain overall effect size under random effects model and then metaregression analyses were performed to identify factors affecting the change in CDAI scores after budesonide treatment. RESULTS Fifteen studies (1875 patients; age, 35.6 years [95% confidence interval (CI): 34.1, 37.0]; 41.66% [95% CI: 37.44, 45.88] males; 33.3% [95% CI: 24.3, 42.3] smokers; weight, 64.7 kg [95% CI: 62.71 66.6] and height, 168 cm [95% CI: 165, 171]) were included. Disease duration was 7.0 years [95% CI: 5.7, 8.2] and duration of the current episode was 3.1 months [95% CI: 1.7, 4.4]. Proportion of patients with prior resection was 42% [95% CI: 34%, 50%]. The disease was 21% in the ileum, 61% in ileocecum, and 18% in the colon. Budesonide dose was 8.83 mg/d [95% CI: 7.52, 10.14]. In a follow-up duration of 21.0 weeks [95% CI: 15.2, 26.8], budesonide treatment was associated with improvement in CDAI score of -117.8 [95% CI: -134.0, -102.0]. The magnitude of the change in CDAI score at the latest follow-up was significantly inversely associated with the percentage of smokers, but positively associated with the baseline CDAI score and duration of the current episode. CONCLUSION Budesonide therapy to Crohn's disease patients appears to be more effective in patients with the more serious condition. Smoking may also affect the prognosis.

Abstract
BACKGROUND More than 50% of patients with Crohn's disease require intestinal resection at least once. Postoperative recurrence (POR) is almost uniform if prophylactic treatment is not started early. Endoscopic monitoring is generally advised. We studied the incidence and management of recurrence in patients who had undergone intestinal resection. METHODS Practicrohn was an observational retrospective study performed in 26 Spanish hospitals including patients aged ≥18 years who underwent Crohn's disease-related ileocolonic resection between January 2007 and December 2010. We recorded preventive treatments, the incidence of clinical recurrence in daily practice, and associated risk factors. RESULTS The study population comprised 314 patients. Median (interquartile range) time from diagnosis to surgery was 6 (1-12) years. Prophylaxis for POR was administered to 208 patients (68%). Endoscopy was performed in 143 (46%) patients the first year after surgery. Clinical POR was detected in 97 patients (31%) after a median 315 (65-748) days. The cumulative probability of clinical POR was 16%, 27%, and 31% at 1, 3, and 5 years, respectively, being higher among patients not receiving immunomodulators as compared to those who received prophylaxis (P = 0.014). Forty-five patients (14%) required reoperation at 5 years after a median time from the first intervention of 228 (133-527) days. CONCLUSIONS In this real-life study, up to one-third of patients with Crohn's disease did not start preventive therapy after intestinal resection, and almost half of them were not endoscopically monitored as recommended. In this setting, 30% of patients developed clinical POR within the first 5 years after surgery, thus indicating that there is room for improvement.

Abstract
The main task of the immune system is to distinguish and respond accordingly to 'danger' or 'non-danger' signals. This is of critical importance in the gastrointestinal tract in which immune cells are constantly in contact with food antigens, symbiotic microflora and potential pathogens. This complex mixture of food antigens and symbionts are essential for providing vital nutrients, so they must be tolerated by the intestinal immune system to prevent aberrant inflammation. Therefore, in the gut the balance between immune activation and tolerance should be tightly regulated to maintain intestinal homeostasis and to prevent hypersensitivity to harmless luminal antigens. Loss of this delicate equilibrium can lead to abnormal activation of the intestinal immune system resulting in devastating gastrointestinal disorders such as inflammatory bowel disease (IBD). Recent evidence supports the idea that the central nervous system interacts dynamically via the vagus nerve with the intestinal immune system to modulate inflammation through humoral and neural pathways, using a mechanism also referred to as the intestinal cholinergic anti-inflammatory pathway. In this review, we will focus on the current understanding of the mechanisms and neuronal circuits involved in the intestinal cholinergic anti-inflammatory pathway. Further investigation on the crosstalk between the nervous and intestinal immune system will hopefully provide new insights leading to the identification of innovative therapeutic approaches to treat intestinal inflammatory diseases.

Abstract
Idiopathic inflammatory bowel diseases (IBD), Crohn’s disease (CD) and ulcerative colitis (UC), are multifactorial diseases that are manifested after disruption of a genetic predisposed individual and its intestinal microflora through an environmental stimulus. Urbanization and industrialization are associated with IBD. Epidemiological data, clinical observations and family/immigrants studies indicate the significance of environmental influence in the development of IBD. Some environmental factors have a different effect on the subtypes of IBD. Smoking and appendectomy is negatively associated with UC, but they are aggravating factors for CD. A westernized high fat diet, full of refined carbohydrates is strongly associated with the development of IBD, contrary to a high in fruit, vegetables and polyunsaturated fatty acid-3 diet that is protective against these diseases. High intake of nonsteroidal antiinflammatory drug and oral contraceptive pills as well as the inadequacy of vitamin D leads to an increased risk for IBD and a more malignant course of disease. Moreover, other factors such as air pollution, psychological factors, sleep disturbances and exercise influence the development and the course of IBD. Epigenetic mechanism like DNA methylation, histone modification and altered expression of miRNAS could explain the connection between genes and environmental factors in triggering the development of IBD.

Abstract
Inflammatory bowel diseases (IBDs), namely Crohn’s disease and ulcerative colitis, are lifelong chronic disorders arising from interactions among genetic, immunological and environmental factors. Although the origin of IBDs is closely linked to immune response alterations, which governs most medical decision-making, recent findings suggest that gut microbiota may be involved in IBD pathogenesis. Epidemiologic evidence and several studies have shown that a dysregulation of gut microbiota (i.e., dysbiosis) may trigger the onset of intestinal disorders such as IBDs. Animal and human investigations focusing on the microbiota-IBD relationship have suggested an altered balance of the intestinal microbial population in the active phase of IBD. Rigorous microbiota typing could, therefore, soon become part of a complete phenotypic analysis of IBD patients. Moreover, individual susceptibility and environmental triggers such as nutrition, medications, age or smoking could modify bacterial strains in the bowel habitat. Pharmacological manipulation of bowel microbiota is somewhat controversial. The employment of antibiotics, probiotics, prebiotics and synbiotics has been widely addressed in the literature worldwide, with the aim of obtaining positive results in a number of IBD patient settings, and determining the appropriate timing and modality of this intervention. Recently, novel treatments for IBDs, such as fecal microbiota transplantation, when accepted by patients, have shown promising results. Controlled studies are being designed. In the near future, new therapeutic strategies can be expected, with non-pathogenic or modified food organisms that can be genetically modified to exert anti-inflammatory properties.

Abstract
AIM: To study statements and recommendations on psychosocial issues as presented in international evidence-based guidelines on the management of inflammatory bowel diseases (IBD).
METHODS: MEDLINE, guidelines International Network, National Guideline Clearing House and National Institute for Health and Care Excellence were searched from January 2006 to June 30, 2013 for evidence-based guidelines on the management of IBD.
RESULTS: The search yielded 364 hits. Thirteen guidelines were included in the review, of which three were prepared in Asia, eight in Europe and two in the United States. Eleven guidelines made statements and recommendations on psychosocial issues. The guidelines were concordant in that mental health disorders and stress do not contribute to the aetiology of IBD, but that they can influence its course. It was recommended that IBD-patients should be screened for psychological distress. If indicated, psychotherapy and/or psychopharmacological therapy should be recommended. IBD-centres should collaborate with mental health care specialists. Tobacco smoking patients with Crohn’s disease should be advised to quit.
CONCLUSION: Patients and mental health specialists should be able to participate in future guideline groups to contribute to establishing recommendations on psychosocial issues in IBD. Future guidelines should acknowledge the presence of psychosocial problems in IBD-patients and encourage screening for psychological distress.

Abstract
Chronic obstructive pulmonary disease (COPD) is currently the third leading cause of death in the world. Although smoking is the main risk factor for this disease, only a minority of smokers develop COPD. Why this happens is largely unknown. Recent discoveries by the human microbiome project have shed new light on the importance and richness of the bacterial microbiota at different body sites in human beings. The microbiota plays a particularly important role in the development and functional integrity of the immune system. Shifts or perturbations in the microbiota can lead to disease. COPD is in part mediated by dysregulated immune responses to cigarette smoke and other environmental insults. Although traditionally the lung has been viewed as a sterile organ, by using highly sensitive genomic techniques, recent reports have identified diverse bacterial communities in the human lung that may change in COPD. This review summarizes the current knowledge concerning the lung microbiota in COPD and its potential implications for pathogenesis of the disease.

Abstract
Despite the availability of biological drugs and the widespread and earlier use of immunosuppressants, intestinal resection remains necessary in almost half of the patients with Crohn's disease. The development of new mucosal lesions in previously unaffected intestinal segments (a phenomenon known as post-operative recurrence, POR) occur within the first year in up to 80% if no preventive measure is started soon after resectional surgery, leading to clinical manifestations (clinical recurrence) and even needing new intestinal resection (surgical recurrence) in some patients. That is the reason why endoscopic monitoring has been recommended within 6 to 12 months after surgery. Active smoking is the only indisputable risk factor for early POR development. Among several evaluated drugs, only thiopurine and anti-tumor necrosis factor therapy seem to be effective and feasible in the long-term both for preventing or even treating recurrent lesions, at least in a proportion of patients. However, to date, it is not clear which patients should start with one or another drug right after surgery. It is also not well established how and how often POR should be assessed in patients with a normal ileocolonoscopy within the first 12 months.

Abstract
The central nervous system interacts dynamically with the immune system to modulate inflammation through humoral and neural pathways. Recently, in animal models of sepsis, the vagus nerve (VN) has been proposed to play a crucial role in the regulation of the immune response, also referred to as the cholinergic anti-inflammatory pathway. The VN, through release of acetylcholine, dampens immune cell activation by interacting with α-7 nicotinic acetylcholine receptors. Recent evidence suggests that the vagal innervation of the gastrointestinal tract also plays a major role controlling intestinal immune activation. Indeed, VN electrical stimulation potently reduces intestinal inflammation restoring intestinal homeostasis, whereas vagotomy has the reverse effect. In this review, we will discuss the current understanding concerning the mechanisms and effects involved in the cholinergic anti-inflammatory pathway in the gastrointestinal tract. Deeper investigation on this counter-regulatory neuroimmune mechanism will provide new insights in the cross-talk between the nervous and immune system leading to the identification of new therapeutic targets to treat intestinal immune disease.

Abstract
The predisposition of cigarette smokers for development of oral and respiratory infections caused by microbial pathogens is well recognised, with those infected with the human immunodeficiency virus (HIV) at particularly high risk. Smoking cigarettes has a suppressive effect on the protective functions of airway epithelium, alveolar macrophages, dendritic cells, natural killer (NK) cells and adaptive immune mechanisms, in the setting of chronic systemic activation of neutrophils. Cigarette smoke also has a direct effect on microbial pathogens to promote the likelihood of infective disease, specifically promotion of microbial virulence and antibiotic resistance. In addition to interactions between smoking and HIV infection, a number of specific infections/clinical syndromes have been associated epidemiologically with cigarette smoking, including those of the upper and lower respiratory tract, gastrointestinal tract, central nervous and other organ systems. Smoking cessation benefits patients in many ways, including reduction of the risk of infectious disease.

Abstract
Context The development of neoplasia is an important concern associated with inflammatory bowel disease (IBD), especially colorectal cancer (CRC). Objectives Our aim was to determine the incidence of intestinal and extraintestinal neoplasias among patients with inflammatory bowel disease. Methods There were retrieved information from 1607 patients regarding demographics, disease duration and extent, temporal relationship between IBD diagnosis and neoplasia, clinical outcomes and risk factors for neoplasia. Results Crohn's disease (CD) was more frequent among women (P = 0.0018). The incidence of neoplasia was higher in ulcerative colitis (UC) when compared to CD (P = 0.0003). Eight (0.99%) patients developed neoplasia among 804 with CD: 4 colorectal cancer, 2 lymphomas, 1 appendix carcinoid and 1 breast cancer. Thirty (3.7%) patients developed neoplasia among the 803 UC: 13 CRC, 2 lymphomas and 15 extraintestinal tumors. While CRC incidence was not different among UC and CD (1.7% vs 0.5%; P = 0.2953), the incidence of extraintestinal neoplasias was higher among UC (2.1% vs 0.5%, P = 0.0009). Ten (26.3%) patients out of 38 with neoplasia died. Conclusions CRC incidence was low and similar in both diseases. There was a higher incidence of extraintestinal neoplasia in UC when compared to CD. Neoplasias in IBD developed at a younger age than expected for the general population. Mortality associated with malignancy is significant, affecting 1/4 of the patients with neoplasia.

Abstract
Background The human intestinal microbiota is a crucial factor in the pathogenesis of various diseases, such as metabolic syndrome or inflammatory bowel disease (IBD). Yet, knowledge about the role of environmental factors such as smoking (which is known to influence theses aforementioned disease states) on the complex microbial composition is sparse. We aimed to investigate the role of smoking cessation on intestinal microbial composition in 10 healthy smoking subjects undergoing controlled smoking cessation. Methods During the observational period of 9 weeks repetitive stool samples were collected. Based on abundance of 16S rRNA genes bacterial composition was analysed and compared to 10 control subjects (5 continuing smokers and 5 non-smokers) by means of Terminal Restriction Fragment Length Polymorphism analysis and high-throughput sequencing. Results Profound shifts in the microbial composition after smoking cessation were observed with an increase of Firmicutes and Actinobacteria and a lower proportion of Bacteroidetes and Proteobacteria on the phylum level. In addition, after smoking cessation there was an increase in microbial diversity. Conclusions These results indicate that smoking is an environmental factor modulating the composition of human gut microbiota. The observed changes after smoking cessation revealed to be similar to the previously reported differences in obese compared to lean humans and mice respectively, suggesting a potential pathogenetic link between weight gain and smoking cessation. In addition they give rise to a potential association of smoking status and the course of IBD.

Abstract
Besides their possible effects on the development of inflammatory bowel disease (IBD), some environmental factors can modulate the clinical course of both ulcerative colitis (UC) and Crohn’s disease (CD). This review is mainly devoted to describing the current knowledge of the impact of some of these factors on the outcome of IBD, with special emphasis on smoking and diet. Although the impact of smoking on the susceptibility to develop CD and UC is firmly established, its influence on the clinical course of both diseases is still debatable. In CD, active smoking is a risk factor for postoperative recurrence. Beyond this clinical setting, smoking cessation seems to be advantageous in those CD patients who were smokers at disease diagnosis, while smoking resumption may be of benefit in ex-smokers with resistant UC. The role of dietary habits on the development of IBD is far from being well established. Also, food intolerances are very frequent, but usually inconsistent among IBD patients, and therefore no general dietary recommendations can be made in these patients. In general, IBD patients should eat a diet as varied as possible. Regarding the possible therapeutic role of some dietary components in IBD, lessons should be drawn from the investigation of the primary therapeutic effect of enteral nutrition in CD. Low-fat diets seem to be particularly useful. Also, some lipid sources, such as olive oil, medium-chain triglycerides, and perhaps omega-3 fatty acids, might have a therapeutic effect. Fermentable fiber may have a role in preventing relapses in inactive UC.
