Srinivas R Rami Reddy, Mitchell S Cappell
PURPOSE OF REVIEW: This study aimed to systematically review small bowel obstruction (SBO), focusing on recent changes in diagnosis/therapy. RECENT FINDINGS: SBO incidence is about 350,000/annum in the USA. Etiologies include adhesions (65%), hernias (10%), neoplasms (5%), Crohn's disease (5%), and other (15%). Bowel dilatation occurs proximal to obstruction primarily from swallowed air and secondarily from intraluminal fluid accumulation. Dilatation increases mural tension, decreases mucosal perfusion, causes bacterial proliferation, and decreases mural tensile strength that increases bowel perforation risks...

AIM: The goal of the work was comparing gas ultrasound images below the right diaphragm in two groups: in people with intestinal interposition below the diaphragm and ones with pneumoperitoneum and extracting the traits differentiating these two conditions. MATERIAL AND METHODS: Retrospectively, the documentation of 22 patients with intestinal interposition below the diaphragm (group 1) was utilized. Clinical material was used for comparison, previously published, composed of 15 cases of pneumoperitoneum following laparotomy and of 14 cases following that symptom as a result of ulcer perforation - group 2 (in total n = 29)...

Small bowel diverticulosis of the jejunum and ileum is an uncommon finding with a prevalence rate of 0.2% to 1.3% at autopsy and 0.3% to 1.9% on small bowel studies. Diagnosis can be difficult because there are no pathognomonic features or clinical symptoms that are specific for small bowel diverticulosis. Though rare, it is critical to keep the possibility of small bowel diverticulosis in mind when evaluating cases of malabsorption, chronic abdominal pain, haemorrhage, perforation and intestinal obstruction, especially in patients with connective tissue disorders, a family history of diverticula and a personal history of colonic diverticulosis...

BACKGROUND AND AIM: Colorectal endoscopic submucosal dissection (ESD) is recommended to be carried out only by endoscopists with sufficient experience in gastric ESD. However, early gastric carcinoma is less common in Western countries than in Japan, and endoscopic maneuverability differs between the stomach and colorectum. We assessed the feasibility of colorectal ESD carried out by endoscopists with no or little experience in gastric ESD. METHODS: We analyzed en bloc resection, R0 resection and perforation rates in 180 consecutive colorectal ESD carried out by three endoscopists who had no or <5 cases of experience in gastric ESD...

We report two cases of bacteremia due to Clostridium difficile from two French hospitals. The first patient with previously diagnosed rectal carcinoma underwent courses of chemotherapy, and antimicrobial treatment, and survived the C. difficile bacteremia. The second patient with colon perforation and newly diagnosed lung cancer underwent antimicrobial treatment in an ICU but died shortly after the episode of C. difficile bacteremia. A review of the literature allowed the identification of 137 cases of bacteremia between July 1962 and November 2016...

BACKGROUND: Traditionally, all patients with a malignant obstruction of the proximal colon (MOPC) are treated with emergency resection. However, recent data suggest that Self-expandable metallic stent (SEMS) placement could lower mortality and morbidity rates. This study therefore aimed to compare SEMS placement with emergency resection as treatment options for MOPC. METHODS: All consecutive patients that underwent SEMS placement for MOPC in the period 2004-2015 at our institution were identified...

BACKGROUND: The tyrosine kinase inhibitor erlotinib improves the outcomes of patients with advanced non-small-cell lung carcinoma (NSCLC) harbouring epidermal growth factor receptor (EGFR) mutations. The coexistence of the T790M resistance mutation with another EGFR mutation in treatment-naive patients has been associated with a shorter progression-free survival to EGFR inhibition than in the absence of the T790M mutation. To test this hypothesis clinically, we developed a proof-of-concept study, in which patients with EGFR-mutant NSCLC were treated with the combination of erlotinib and bevacizumab, stratified by the presence of the pretreatment T790M mutation...

BACKGROUND: Patients with diverticulitis are predisposed to hepatic abscesses via seeding through the portal circulation. Hepatic abscesses are well-documented sequelae of diverticulitis, however instances of progression to hepato-bronchial fistulization are rare. We present a case of diverticulitis associated with hepatic abscess leading to hepato-bronchial fistulization, which represents a novel disease course not yet reported in the literature. CASE PRESENTATION: A 61-year-old Caucasian man presented with a history of unintentional weight loss and dyspnea both at rest and with exertion...

Ulcerative Colitis (UC) is a chronic inflammatory disease involving the colon, with alternating periods of remission and activity. Exacerbations can be severe and associated with complications and mortality. Diagnosis of severe UC is based on clinical, biochemical and endoscopic variables. Patients with severe UC must be hospitalized. First line therapy is the use of intravenous corticoids which achieve clinical remission in most patients. However, 25% of patients will be refractory to corticoids, situation that should be evaluated at the third day of therapy...

Cribriform is a histopathological term used to describe a neoplastic epithelial proliferation in the form of large nests perforated by many quite rounded different-sized spaces. This growth pattern may be seen in carcinomas arising in different organs, and shows important prognostic implications. Therefore, recent data in literature suggest that cribriform carcinoma is a histologically and clinically distinctive type of tumour that should be separated from other similar tumour types. In this article, the pathology of cribriform adenocarcinoma of the prostate, lung, breast, stomach, colon, thyroid, and skin is discussed with particular reference to morphologic and immunohistochemical features, differential diagnosis, and clinical behaviour...

CT colonography is a CT examination focused on the detection of colonic polyps and masses. Its most common indications include incomplete optical colonoscopy and generally personal preference in symptomatic or frail patients. CT colonography has a diagnostic yield similar to optical colonoscopy. It is less demanding for the patient, has shorter examination times, lower rates of adverse effects (including bowel perforation) and allows limited evaluation of extracolonic structures. In 10-15 % of asymptomatic patients, optical colonoscopy is needed if either a colonic polyp or mass is detected...

OBJECTIVE: To compare clinical outcomes after laparoscopic lavage (LL) or colonic resection (CR) for purulent diverticulitis. BACKGROUND: Laparoscopic lavage has been suggested as an alternative treatment for traditional CR. Comparative studies to date have shown conflicting results. METHODS: Electronic searches of Embase, Medline, Web of Science, and Cochrane databases were performed. Weighted mean differences (WMD) were calculated for effect size of continuous variables and pooled odds ratios (POR) calculated for discrete variables...

INTRODUCTION: The use of a self-expanding metallic stent as a bridge to surgery in acute malignant left colonic obstruction has been suggested as an alternative treatment to emergency surgery. The aim of the present study was to compare the morbi-mortality, cost-benefit and long-term oncological outcomes of both therapeutic options. METHODS: This is a prospective, comparative, controlled, non-randomized study (2005-2010) performed in a specialized unit. The study included 82 patients with left colon cancer obstruction treated by stent as a bridge to surgery (n=27) or emergency surgery (n=55) operated with local curative intention...

Background and study aims Colonic polyps > 1 cm in size are commonly managed using hot polypectomy techniques. The most frequent adverse events (delayed bleeding, post-polypectomy syndrome, and perforation) are related to electrocautery-induced injury. We hypothesized that cold resection of large polyps may have similar efficacy and improved safety compared to hot polypectomy. Our aims were to evaluate efficacy and safety of piecemeal cold snare resection of colonic polyps > 1 cm. Patients and methods Patients undergoing lift and piecemeal cold snare polypectomy of non-pedunculated colon polyps > 1 cm from October 2013 to September 2015 were identified retrospectively...

Colonoscopy is being widely used since the 1980s and is the leading diagnostic procedure for colorectal cancer. For many colorectal diseases, it is also a therapeutic tool. Like many other procedures in Medicine, it has its drawbacks and complications, some of which if not readily diagnosed can represent a serious risk to the patient's health and well-being. We describe a case of colon perforation during diagnostic colonoscopy in a patient, resulting in exuberant pneumoretroperitoneum, pneumoperitoneum, pneumomediastinum and subcutaneous emphysema, who successfully underwent laparoscopic colonic resection with primary anastomosis...

Esophageal or gastric injuries secondary to caustic substance ingestion is still an important issue in developing countries. Its clinical spectrum can vary from absence of mucosal injury to complications such as severe burns, strictures and perforation. Physical examination and first endoscopic evaluation are very important in the diagnosis. The objective of this study is to present 154 children who were undergone upper gastrointestinal endoscopy because of caustic substance ingestion including descaler, degreaser, unlabeled bleach, drain opener, surface cleaner, dishwasher rinse aid, hydrochloric acid...

Rectal perforation is uncommon in ovarian cancer, even in advanced stages. Pure primary ovarian squamous cell carcinoma is a very rare subtype of ovarian cancer and has not been reported to cause rectal perforation. A 50-year-old woman presented with rectal bleeding. Rectosigmoidoscopy suggested perforation of a pelvic tumor into the rectum. Abdominopelvic magnetic resonance imaging revealed a 9 cm heterogeneous mass in the pouch of Douglas. We performed complete cytoreduction, including an en-bloc resection of the tumor and rectosigmoid colon...

Data regarding management of colonic diverticulitis in renal transplant recipients (RTRs) are limited. This study aims to identify prevalence, risk factors, and outcomes in RTRs with colonic diverticulosis and diverticulitis. Between January 2004 and December 2013, all patients who underwent kidney transplantation were analyzed. Among all RTSs, patients who had a pretransplant colonoscopic diagnosis of diverticulosis and patients with a proven attack of diverticulitis were included in our analysis. There were 1578 RTRs with a mean age of 50 ± 14 years at the time of transplantation...

BACKGROUND AND AIMS: The colonic self-expanding metal stent (SEMS) has been widely used for "bridge to surgery" and palliative therapy. However, if the spread of SEMS is insufficient, not only can a decompression effect not be obtained but also perforation and obstructive colitis can occur. The mechanism of occurrence of obstructive colitis and perforation was investigated by flow dynamics. METHODS: Bernoulli's principle was applied, assuming that the cause of inflammation and perforation represented the pressure difference in the proximal lumen and stent...
