RESUMO

OBJECTIVE: To conduct a review of the literature on foetal volvulus with emphasis on prenatal imaging, pregnancy characteristics and clinical outcomes. METHODS: A review of all published cases of foetal volvulus diagnosed prenatally and indexed in Medline, EBSCOhost, CINAHL, SOCIndex and Healthy Policy Reference Centre. Studies without antenatal sonographic signs of foetal volvulus and without a postpartum surgical diagnosis were excluded. Data were analysed for frequencies and distributions and tested for statistical significance. RESULTS: Eighty-eight cases of foetal volvulus were identified from 58 published case reports/series. The most common ultrasound findings were dilated bowel/stomach (77.3%), polyhydramnios (30.7%) and whirlpool/snail sign (28.4%). Median gestation at diagnosis was 31.9 weeks (IQR 27-34) and mean gestation at delivery was 34.5 weeks (SD 2.8). Underlying aetiology included intestinal malrotation (15.9%), cystic fibrosis (14.8% of all cases, 32.5% of tested cases) and abnormal mesenteric fixation (12.5%). Complications included intestinal atresia (36.4%) and foetal anaemia (9.1%). The overall perinatal mortality rate was 14.5%. CONCLUSION: Foetal volvulus is a rare condition with high rates of preterm birth and perinatal mortality. Intestinal malrotation and cystic fibrosis are common predisposing causes, although the majority are idiopathic. Bowel and/or gastric dilatation is by far the most common sonographic finding.

RESUMO

Thyroid storm is an unusually rare but life-threatening pediatric occurrence, carrying significant mortality. Skewed towards the adolescent population, thyroid decompensation occurs due to inciting factors ranging from infection, trauma, surgery, burns, medications, direct thyroid trauma, and rarely volvulus. Emergent care focuses on both reversing the inciting event as well as quelling the metabolic hyperactivity associated with thyroid storm. In review of the available literature, this case is the first to date of thyroid storm secondary to malrotation with midgut volvulus in a previously euthyroid adolescent patient.

RESUMO

PURPOSE: Midgut volvulus is associated with intestinal ischemia/reperfusion (IR) injury and can progress to severe intestinal damage. Remote ischemic conditioning (RIC) reduces IR-induced injury in distant organs. The aim of this study was to investigate whether RIC protects the intestine from IR injury. METHODS: We investigated intestinal IR injury in 3 weeks old SD rats. Animals underwent: (i) sham laparotomy, (ii) intestinal IR injury, (iii) intestinal IR + RIC during ischemia, or (iv) intestinal IR + RIC after reperfusion. Intestinal IR injury was achieved by 45 min occlusion of superior mesenteric artery followed by de-occlusion. RIC was administered via four cycles of 5 min of hind limb ischemia followed by 5 min reperfusion. Animals were sacrificed 24 h after surgery and the ileum was harvested for evaluation. RESULTS: Intestinal injury was present after IR. However, this injury was reduced in both IR + RIC groups. Expression of inflammatory cytokine IL6 was lower in IR + RIC groups compared to IR alone. Carbonyl protein was also significantly lower in IR + RIC compared to IR, indicating lower oxidative stress in both IR + RIC groups. CONCLUSION: Remote ischemic conditioning attenuated intestinal injury, inflammation, and oxidative stress in experimental intestinal ischemia/reperfusion injury. Remote ischemic conditioning may be useful in children with midgut volvulus to reduce the intestinal injury. LEVEL OF EVIDENCE: Experimental study. TYPE OF STUDY: Animal experiment.

RESUMO

Cecal bascule is a form of volvulus resulting from upward and anterior cecal folding, and accounts for 0.01% of adult large bowel obstructions. With a competent ileocecal valve, cecal bascule may progress to closed loop obstruction, ischemia, gangrene, or perforation. Failure to treat cecal bascule has a mortality of 50%. Nonoperative management includes nasogastric and colonoscopic decompression, with a 95% failure rate. The gold standard is right hemicolectomy with a near nonexistent recurrence rate. Severe gastrointestinal complications following cardiothoracic surgery may lead to increased morbidity, length of stay, and mortality. Here, we present the first reported case of cecal bascule following cardiac surgery.

RESUMO

OBJECTIVES: Although systemic sclerosis (SSc) is known to affect the gastrointestinal (GI) tract, most of the literature focuses on esophageal, small intestinal, or anorectal manifestations. There have been no reviews focused on large bowel SSc complications in over 30 years. The aim of this study is to perform a systematic review of colonic manifestations and complications of SSc. METHODS: An experienced librarian conducted a search of databases, including English and Spanish articles. The search used keywords including "systemic sclerosis," "scleroderma," and "colon." A systematic review was performed using Preferred Reporting Items for Systematic Review and Meta-Analyses guidelines. Case reports/series were screened for validity by adapting from criteria published elsewhere. RESULTS: Of 1,890 articles, 74 met selection criteria. Fifty-nine of the 77 articles were case reports/series. The most common article topics on colonic SSc complications were constipation/dysmotility (15), colonic volvulus (8), inflammatory bowel disease (7), microscopic colitis (6), megacolon (6), and telangiectasia (6). Colonic manifestations constituted 24% of articles on GI complications of SSc. There were a total of 85 cases (84% women, with a median age of onset of colon complication of 52 years). Limited cutaneous SSc phenotype (65.6%) was more common than diffuse (26.2%). Patients frequently had poor outcomes with high mortality related to colonic complications (27%). Recent studies explore contemporary topics such as the microbiome in SSc and prucalopride for chronic constipation in SSc. DISCUSSION: Colonic complications comprise a large proportion of the published reports on GI symptoms afflicting patients with SSc and require raised diagnostic suspicion and deliberate action to avoid potentially serious complications including death.

RESUMO

RATIONALE: Complete small intestinal volvulus is a rare entity in adults, unlike partial intestinal volvulus. Although prompt surgical intervention is the mainstay of treatment, attention should also be paid to recovery of intestinal function postoperatively. Ignoring this issue during the postoperative recovery process can have serious consequences. We report the case of an 82-year-old woman with complete small intestinal volvulus at the root of the superior mesenteric vessel. PATIENTS CONCERNS: The patient was admitted for acute onset (22 hours) of abdominal pain and distention. Nausea and vomiting also developed during this period. DIAGNOSES: Abdominal physical examination was suspicious for peritoneal irritation. Computed tomography scan showed anticlockwise swirl of the mesenteric vessels at the lower margin of the pancreas with distension of the entire small intestine. A complete small intestinal volvulus was diagnosed. INTERVENTIONS: Laparotomy and detorsion of the volvulus were performed after early diagnosis. OUTCOMES: The patient developed intestinal wall edema because of ischemic-reperfusion damage. She exhibited severe abdominal distention and absent intestinal motility. Two days later, she went into septic shock; she died 19 days after surgical intervention. LESSONS: Because complete small intestinal volvulus involves the entire intestine, ischemic-reperfusion intestinal damage after detorsion may be severe and can predict prognosis.

RESUMO

INTRODUCTION: Sublingual microcirculation monitoring is suitable for bedside use in critically ill patients. We present a case in which severely impaired sublingual microcirculation was the first alarming sign of an early deterioration of the patient's medical situation. CASE PRESENTATION: This is the case of a 58-year-old white woman admitted to our intensive care unit after the removal of parts of her small intestine due to a volvulus. Her microcirculation was checked the day after surgery in terms of an ongoing study and predicted a massive deterioration of her clinical situation. CONCLUSIONS: This case highlights the potential value of monitoring the microcirculation in critically ill patients. Two full hours could have been saved for diagnostic workup and earlier treatment had we considered the impaired microcirculation alone as a warning sign. Regardless of the supposed cause, impaired microcirculation should alert the responsible physician and should be followed by a diagnostic workup. Sublingual microcirculation monitoring can be useful in intensive care units to detect a deteriorated microcirculation earlier than with standard monitoring.

RESUMO

BACKGROUND: Intestinal malrotation (IM) is an uncommon condition and has varied presentation in different age groups. The study was aimed to evaluate differences in the clinical presentation, diagnosis, treatment, and outcome of IM in infants, children, and adults. METHODS: Data were collected from records of 79 patients with IM. Based on the age of presentation, these patients were categorized into three age groups: infants (up to 1 year), children (1-18 years), and adults (> 18 years). Follow up data were analyzed during 8 to 16 year after corrective surgery. RESULTS: The overall age of presentation ranged from 8 days to 60 years. Twenty-eight, 29, and 22 patients belonged to the infant, children, and adult groups, respectively. The classical presentation of IM (bilious vomiting) was significantly higher in the infant compared to the children and adult groups (100% vs. 62% vs. 9.8%; p < 0.001). All infants presented with acute symptoms. However, children and adults had subacute or chronic presentations, respectively. The incidence of volvulus was significantly higher in the infant group than other two groups, (100% vs. 41% vs. 10%; p < 0.001). Doppler ultrasound was highly accurate in infants (100%), whereas contrast-enhanced computed tomography (CECT) abdomen was found to be most useful in adults. Postoperative complications were more common in adults. CONCLUSION: Intestinal malrotation can present in patients of any age group. An increased awareness about the atypical presentations of this condition among adults may reduce the time to accurate diagnosis of this disease.

RESUMO

BACKGROUND: Sigmoid volvulus is frequently reported in the "volvulus belt" (Middle East, Africa, the Indian subcontinent, Turkey, and South America) and is the third leading cause of large bowel obstruction in North America. It is an uncommon problem in children and adolescents, and is rarely considered a diagnosis in this group. A high index of suspicion is necessary to diagnose sigmoid volvulus in children. CASE PRESENTATION: We present a 13-year-old Arabian girl who came with features suggestive of intestinal obstruction. Plain abdominal film revealed classic omega (coffee bean) sign of sigmoid volvulus. The volvulus was successfully decompressed by means of a rectal tube in our emergency department. The next day during the same admission the volvulus recurred and was successfully decompressed by endoscopy. She was discharged home on her parents' request; she presented again 1 month later. This time the volvulus could not be decompressed non-operatively, so she underwent sigmoidectomy with primary anastomosis. Postoperatively she developed paralytic ileus that resolved after 10 days. Following that she did well and was discharged home. She is still free of symptoms 1 year after the resection. CONCLUSIONS: Sigmoid volvulus is an uncommon problem in children and adolescents, and is rarely considered a diagnosis in this group as a cause of intestinal obstruction. Pediatric surgeons should maintain a high index of suspicion, in order not to miss this important diagnosis, as any delay in instituting treatment has a devastating effect on morbidity as well as mortality. Early diagnosis and prompt treatment confer an excellent prognosis.

RESUMO

BACKGROUND/AIM: The aim is to evaluate the long-term outcome of asymptomatic patients who underwent surgical correction for midgut volvulus. MATERIALS AND METHODS: Seven patients managed surgically for midgut volvulus in the last 3 years were included. Demographic features, symptoms at presentation, diagnoses, surgical procedures, and complications were recorded. Patients were then contacted for follow-up and evaluation of long-term outcomes. General physical conditions, anthropometric parameters, feeding habits, and defecation histories were evaluated. Laboratory examinations were performed. Color Doppler ultrasonography (CDUS) was performed to evaluate blood flow in the superior mesenteric artery (SMA). RESULTS: In total, seven patients were identified. The median age at admission was 3 days (0-90 days). Mean age at follow-up was 17 ± 2 months. Growth parameters were normal in all cases. Four patients had low levels of ferritin and transferrin saturation. One patient had microcytic anemia. Another patient had low serum zinc level. One patient who had ileal resection had a high level of steatorrhea in stool examination. In CDUS, SMA blood flow volume was low in all cases. Peak-systolic velocity and resistance index were low in all but one case. CONCLUSION: Despite uneventful postoperative courses, all patients operated on for midgut volvulus showed mild laboratory changes and decreased blood flow in the SMA in long-term follow-up.

RESUMO

"Serpentine-like syndrome" is a severe and rare association of multiple congenital malformations, characterised by brachioesophagus, secondary intrathoracic stomach, and vertebral anomalies. Other associated anomalies have been described, such as malposition and herniation of abdominal organs. We report the natural history of a baby girl born at 29 weeks of gestation with intra uterine growth restriction, short neck, large rachischisis from cervical to thoracic spine, a very short oesophagus, thoracic stomach associated with a midline diaphragmatic hernia, malrotated gut and median cleft lip. Most of these anomalies were detected antenatally. Molecular karyotype was normal. She died at age 12 days. To our knowledge, the present patient represents the 8th report of a case of "Serpentine-like syndrome". Brachioesophagus and congenital vertebral anomalies, in particular rachischisis, are the cardinal features of this condition. All reported cases have been sporadic and the cause is still unknown. We believe that the specificity of the presentation as well as the similarities between available descriptions of patients suggests a common, yet to identify, molecular cause, possibly involving a developmental "toolkit"/homeobox gene or related pathways.
