S Gaines, C Shao, N Hyman, J C Alverdy
BACKGROUND: The pathogenesis of colorectal cancer recurrence after a curative resection remains poorly understood. A yet-to-be accounted for variable is the composition and function of the microbiome adjacent to the tumour and its influence on the margins of resection following surgery. METHODS: PubMed was searched for historical as well as current manuscripts dated between 1970 and 2017 using the following keywords: 'colorectal cancer recurrence', 'microbiome', 'anastomotic leak', 'anastomotic failure' and 'mechanical bowel preparation'...

PURPOSE/BACKGROUND: Meckel's diverticulum (MD) is one of the most common congenital malformations of gastrointestinal tract in children. However, the nonspecific clinical manifestations of MD often cause a diagnostic as well as therapeutic challenge to pediatric surgeon. This study aimed to review our experience in managing this disease while evaluating the management strategies. METHODS: We retrospectively analyzed the clinical data of all patients diagnosed with MD admitted to our center between January 2010 and December 2015...

INTRODUCTION: The type of anastomosis of the pancreas following pancreaticoduodenectomy is often attributed to the reason for pancreatic leak. Results of various randomized trials comparing pancreaticojejunostomy and pancreaticogastrostomy are conflicting one suggesting advantage over the other and vice versa. In this study we intend to critically analyze a novel technique of binding pancreaticogastrostomy following pancreaticoduodenectomy. AIMS AND OBJECTIVES: The aim of this study is to see the outcome of binding pancreaticogastrostomy by evaluating the technical aspects of binding PG and study the incidence of post-operative complications...

PURPOSE: Conventional transperitoneal radical cystectomy (TPRC) is the standard approach for muscle invasive bladder cancer. But, the procedure is associated with significant morbidities like urinary leak, ileus, and infection. To reduce these morbidities, the technique of extraperitoneal radical cystectomy (EPRC) was described by us in 1999. We compared these two approaches and the data accrued forms the basis of this report. MATERIALS AND METHODS: All patients who underwent radical cystectomy for bladder cancer by the author (JNK) with follow-up for at least 5 years were included...

Anastomotic leak (AL) is a serious complication of intestinal surgery with various predisposing factors. This study aims to assess several risk factors associated with AL after small intestinal and colonic anastomoses through a multivariate analysis. Two hundred twenty-four patients (126 males) with intestinal anastomosis of a median age of 44 years were reviewed. Independent factors associated with AL were male gender (OR = 2.59, P = 0.02), chronic liver disease (CLD) (OR = 8.03, P < 0.0001), more than one associated comorbidity (OR = 5...

Alcohol consumption promotes loss of intestinal barrier function. However, mechanisms by which ethanol affects the tight junction (TJ), the cellular structure responsible for maintaining the gut epithelial barrier, are not well understood. Three classes of transmembrane proteins comprise TJs: occludin, claudins, and junctional adhesion molecules (JAMs). It has recently been postulated that JAM-A (F11R), the most abundant JAM expressed in intestinal epithelium, regulates "leak" pathway flux, a paracellular route for the nonselective permeation of large solutes...

Gastrointestinal resections are a common operation and most involve an anastomosis to re-join the ends of the remaining bowel to restore gastrointestinal (GIT) continuity. While most joins heal uneventfully, in up to 26% of patients healing fails and an anastomotic leak (AL) develops. Despite advances in surgical technology and techniques, the rate of anastomotic leaks has not decreased over the last few decades raising the possibility that perhaps we do not yet fully understand this phenomenon of AL and are thus ill-equipped to prevent it...

The rich component of lymphatics makes the intestine prone to leaks of lymph after transplantation secondary to their transection during procurement. We describe our technique for isolation and ligation of the small lymphatics at the root of the mesentery during the procurement of the small intestine and report our experience with the management of lymphatic leaks posttransplant.

The umbilicus is involved in a wide range of abnormalities in infants and children. The most severe are evident at birth and include exomphalos (omphalocele) and gastroschisis, both of which can be life-threatening but are easy to diagnose. Exomphalos is often associated with other congenital abnormalities, whereas the associated problems in gastroschisis are largely confined to the gut. Infection of the umbilicus in the neonate presents as omphalitis. The causes of a moist umbilicus following separation of the umbilical stump are multiple, from the relatively minor umbilical granuloma or ectopic bowel mucosa to the more significant patent urachus that leaks urine...

PURPOSE: The safety and effectiveness of a stapled intestinal anastomosis in adults, children, and infants is well documented. However, in neonates it is not well validated. We hypothesized that premature infants who received a stapled bowel anastomosis utilizing endoscopic staplers had similar outcomes compared to patients with a handsewn anastomosis. METHODS: A retrospective study was performed reviewing premature infants who underwent an intestinal anastomosis over a 4-year period...

Inflammatory bowel disease (IBD) is associated with decreased bone mass and alterations in bone geometry from the time of diagnosis, before anti-inflammatory therapy is instituted. Deficits in bone mass can persist despite absence of symptoms of active IBD. The effects of IBD on the skeleton are complex. Protein-calorie malnutrition, inactivity, hypogonadism, deficits in calcium intake and vitamin D consumption and synthesis, stunted growth in children, decreased skeletal muscle mass, and inflammation all likely play a role...

INTRODUCTION: Magnamosis forms a compression anastomosis using self-aligning magnetic Harrison rings. The device has been approved by the Food and Drug Administration for first-in-human testing and has been applied in adults for intestinal anastomosis during urologic reconstructions. We now report the first cases of magnamosis to functionally undivert the fecal stream from a previously created loop ileostomy in pediatric patients. MATERIALS AND METHODS: Case 1: A 4-year-old male underwent a diverting loop ileostomy for malignant bowel obstruction...

AIM: To efficiently replicate the biology and pathogenesis of human esophageal adenocarcinoma (EAC) using the modified Levrat model of end-to-side esophagojejunostomy. METHODS: End-to-side esophagojejunostomy was performed on rats to induce gastroduodenoesophageal reflux to develop EAC. Animals were randomly selected and serially euthanized at 10 (n = 6), 17 (n = 8), 24 (n = 9), 31 (n = 6), 38 (n = 6), and 40 (n = 6) wk postoperatively. The esophagi were harvested for downstream histopathology and gene expression...

Clostridium perfringens enterotoxin (CPE) causes food poisoning and antibiotic-associated diarrhea. It uses some claudin tight junction proteins (e.g. claudin-4) as receptors to form Ca2+-permeable pores in the membrane damaging epithelial cells in small intestine and colon. We demonstrate that only a subpopulation of colonic enterocytes which are characterized by apical dislocation of claudins are CPE-susceptible. CPE-mediated damage was enhanced if paracellular barrier was impaired by Ca2+-depletion, proinflammatory cytokine TNFα or dedifferentiation...

Background: Hantaviruses are zoonotic agents that cause hemorrhagic fevers and are thought to be transmitted to humans by exposure to aerosolized excreta of infected rodents. Puumala virus (PUUV) is the predominant endemic hantavirus in Europe. A large proportion of PUUV-infected patients suffer from gastrointestinal symptoms of unclear origin. In this study we demonstrate that PUUV infection can occur via the alimentary tract. Methods: We investigated susceptibility of the human small intestinal epithelium for PUUV infection and analyzed the resistance of virions to gastric juice...
