Internal hernia through the foramen of Winslow: a rare cause of intestinal obstruction with imminent ischaemia of the caecum.

An internal hernia through the foramen of Winslow represents a rare surgical pathology. This report describes a case with incipient caecal ischaemia and discusses current diagnostic and therapeutic approaches. A patient in his early 60s presented at the emergency department with abdominal pain and last bowel movement three days prior. A CT scan of the abdomen suggested an internal hernia into the lesser sac. Intraoperatively, the suspected diagnosis could be confirmed laparoscopically with a twisted mobile caecum herniating through the foramen of Winslow. Due to a suspected ischaemia and laparoscopic frustrated reduction, a right open hemicolectomy was performed. The hernia gap was closed. The postoperative course was uneventful. Despite the rarity of internal hernias in patients without prior abdominal surgery, surgeons should be aware of this entity. The diagnosis can be difficult and sometimes only established intraoperatively. Open surgery is usually required. If the gap is clearly identified, the recommendations tend towards its closure.

Case Report: Caecal volvulus management from diagnosis to treatment in a young patient.

Caecal volvulus (CV) is a rare cause of intestinal obstruction, defined by an axial torsion of the caecum, ascending colon, and terminal ileum around the mesenteric vascular pedicles, leading to ischemia and bowel necrosis. A 20-year-old woman, with no significant medical history, was admitted for generalized abdominal pain evolving for three days, along with constipation and abdominal distension, but with no vomiting. Physical examination showed a generalized abdominal tenderness with no rigidity or rebound tenderness, associated with abdominal distension and tympanic upon percussion. Laboratory findings were within normal limits. An abdominal computed tomography scan revealed distension of a loop of the large bowel with its long axis extending from the right lower quadrant to the epigastrium or left upper quadrant. Colonic haustral pattern was absent. An abdominal computed tomography scan showed a rounded focal collection of air-distended bowel with haustral creases in the upper left quadrant. In addition, spiraled loops of the collapsed cecum (giving a whirl sign) were noted, along with low-attenuating fatty mesentery from the twisted bowel. The patient underwent an emergency laparotomy and caecectomy using GEA 80 charges. The patient had no complaints post-operation. CV is a rare cause of bowel obstruction, mainly caused by an exceedingly mobile caecum. Despite its rareness, CV represents the second most common cause of large bowel volvulus, behind sigmoid volvulus. For acute obstruction by CV, it is hard to differentiate it clinically from obstruction of the small bowel; therefore, radiological exams are needed. Surgery is the gold standard treatment for CV. We report a rare case of CV to highlight the rarity of this pathology, specify its diagnostic and therapeutic means, and its clinical and biological evolution.

[A Case of Cecal Burkitt's Lymphoma with Intussusception].

We report a case of ileocecal intussusception due to Burkitt's lymphoma(BL). A 14-year-old boy was admitted to our hospital for abdominal pain and diarrhea. He was diagnosed an intussusception by the ultrasonography and the CT scan. Laparoscopic ileocecal resection was performed. A diagnosis of BL was made on basis of pathological examination. He was transferred for the chemotherapy on postoperative day 8. We conclude that, if the intussusception associated with malignant lymphoma is assumed from the preoperative findings, we have to keep minimal surgical invasion and start postoperative chemotherapy immediately.

Comparison between children and adults intussusception. Description of two cases and review of literature.

INTRODUCTION: Intussusception is a common condition in children, it is rare in adults. Adult intussusception differs from pediatric intussusception in various respects, including etiology clinical characteristics and therapy. METHODS: We present and discuss a new case of intussusception in children and adults. RESULTS: In child the Barium Enema x-ray examination is identified an endoluminal filling defect to refer to the apex of the invaginated loop at the rectal level, with slow ascent during the progressive injection of the radiopaque contrast medium. At the end of the procedure, incomplete reduction of the picture is documented. The patient undergoes emergency surgery where the presence of an ileo-ceco-colic invagination is documented. Intussusception is reduced by taxis. In the adult laparoscopic right hemicolectomy was performed. High-grade B-cell Burkitt's lymphoma was confirmed by immunohistochemistry. DISCUSSION: In contrast to intussusceptions in children, in the adult population, a demonstrable etiology is found in most of the cases. In adults surgery is always indicated. The non-invasive resolutive intervention most commonly used in the child and best known consists in the rectal introduction of a radiopaque contrast medium (air or barium) at controlled pressure until. CONCLUSIONS: Although intussusceptions occur at all ages, there are major differences in the clinical presentation, diagnostic approach, and management between pediatric and adult populations. Intussusception is remarkably different in these two age groups and it must be approached from a different clinical perspective. KEY WORDS: Intussusception in children, Intussusception in adults, Intussusception symptoms, Radiology and treatment.

Prevalence of Appendicoliths Detected at CT in Adults With Suspected Appendicitis.

OBJECTIVE. With heightened interest in nonoperative antibiotic management of uncomplicated appendicitis, appendicoliths become a more relevant issue, and because of higher failure rates their presence may be considered a contraindication. The purpose of this study was to investigate the prevalence of appendicoliths at CT in adults with suspected appendicitis. MATERIALS AND METHODS. Among adults undergoing MDCT for suspected appendicitis, 248 patients (134 women, 114 men; mean age, 35.2 years) consecutively registered over a 3-year period constituted a cohort with surgically proven appendicitis. A cohort of 248 patients (175 women, 73 men; mean age, 37.7 years) without appendicitis consecutively registered over a 1-year period served as control subjects. CT examinations were reviewed for the presence, size, and attenuation of appendicoliths and whether the appendicoliths were obstructing. In the cohort with appendicitis, degree of inflammation (3-point scale) and likelihood for perforation (5-point scale) were scored. RESULTS. The prevalence of appendicoliths at CT was 38.7% (96/248) among patients with appendicitis and 4.4% (11/248) among control subjects (p < .001). Among the 96 patients with appendicitis who had visible appendicoliths, mean width, length, and maximum attenuation of the dominant appendicolith were 6.0 mm, 8.2 mm, and 313 HU, respectively. In 70.8% (68/96) of patients appendicoliths were obstructing, and 32.3% (31/96) of patients had more than one appendicolith. Inflammation (1.75 vs 1.43) and likelihood of perforation (2.07 vs 1.51) (p < .05) scores were higher among patients with appendicitis who had appendicoliths. Extraluminal appendicoliths were seen in five cases of perforated appendicitis. CONCLUSION. Appendicoliths were identified at CT in nearly 40% of adults with proven appendicitis, compared with slightly more than 4% of those without appendicitis, and were associated with increased inflammation and risk of perforation.

'Ball valve' small bowel obstruction caused by a large caecal faecolith.

Small bowel obstruction is a common surgical presentation, but intestinal faecoliths are rarely reported as a cause. A 75-year-old woman presented with small bowel obstruction from a large faecolith lodged in the caecum. This required removal at laparoscopy-assisted surgery. This case highlights the need to deal promptly with symptomatic intestinal faecoliths as they are unlikely to pass spontaneously and are prone to cause acute obstruction.

Rare cause of right iliac fossa pain in a UK patient.

A 62-year-old Asian man presented with a 3-month history of right iliac fossa pain which had progressively worsened over the last 3 weeks. All blood parameters were found to be unremarkable except for mildly elevated erythrocyte sedimentation rate. CT imaging demonstrated thickening of the ascending colon and caecum. Colonoscopic biopsies showed submucosal granulomas with features suggestive of schistosomiasis and parasite serology was positive for Schistosoma antibodies. He was treated with praziquantel and showed subsequent symptomatic and radiological improvement. However, he represented nearly 2 years later and underwent a right hemicolectomy for small bowel obstruction. The resected bowel showed an inflammatory caecal mass and a terminal ileal adenocarcinoma.

Fish oil-rich lipid emulsion modulates neuroinflammation and prevents long-term cognitive dysfunction after sepsis.

OBJECTIVES: Sepsis is a severe organic dysfunction caused by an infection that affects the normal regulation of several organ systems, including the central nervous system. Inflammation and oxidative stress play crucial roles in the development of brain dysfunction in sepsis. The aim of this study was to determine the effect of a fish oil (FO)-55-enriched lipid emulsion as an important anti-inflammatory compound on brain dysfunction in septic rats. METHODS: Wistar rats were subjected to sepsis by cecal ligation and perforation (CLP) or sham (control) and treated orally with FO (600 µL/kg after CLP) or vehicle (saline; sal). Animals were divided into sham+sal, sham+FO, CLP+sal and CLP+FO groups. At 24 h and 10 d after surgery, the hippocampus, prefrontal cortex, and total cortex were obtained and assayed for levels of interleukin (IL)-1ß and IL-10, blood-brain barrier permeability, nitrite/nitrate concentration, myeloperoxidase activity, thiobarbituric acid reactive species formation, protein carbonyls, superoxide dismutase and catalase activity, and brain-derived neurotrophic factor levels. Behavioral tasks were performed 10 d after surgery. RESULTS: FO reduced BBB permeability in the prefrontal cortex and total cortex of septic rats, decreased IL-1ß levels and protein carbonylation in all brain structures, and diminished myeloperoxidase activity in the hippocampus and prefrontal cortex. FO enhanced brain-derived neurotrophic factor levels in the hippocampus and prefrontal cortex and prevented cognitive impairment. CONCLUSIONS: FO diminishes the negative effect of polymicrobial sepsis in the rat brain by reducing inflammatory and oxidative stress markers.

A Rare Cause of Septic Shock in the Emergency Department in an Intellectually-Disabled Child.

BACKGROUND: Sepsis in older children is often associated with the presence of developmental abnormalities and cerebral palsy. While relatively uncommon, surgical abdomen in these patients is associated with a high rate of mortality. Few reports have been described of sepsis caused by isolated cecal necrosis. CASE REPORT: We report a 13-year-old child with cerebral palsy and global developmental delay who presented to the emergency department with acute worsening abdominal distention that the mother attributed to chronic constipation. Clinical evaluation revealed that she was in severe septic shock and needed immediate stabilization after which she underwent an exploratory laparotomy. Operative findings revealed cecal necrosis that necessitated an ileocecectomy. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Children with intellectual disabilities presenting with sepsis to the emergency department can be particularly challenging given the communication barriers and the time-sensitive nature of the condition. When evaluating these patients, a thorough history and examination are often the only tools that assist in the early identification of the infectious source, leading to improved clinical outcomes.© 2019 Elsevier Inc.
