Gastrointestinal motility should be emphasized after laparotomy treatment for complete small intestinal volvulus in older adults: A case report

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.

Comparative study of intestinal malrotation in infant, children, and adult in a tertiary care center in India

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.

Effects of ischemia and reperfusion on eosinophilic accumulation and distribution in mucosa of equine jejunum and colon

OBJECTIVE To evaluate the eosinophilic response in intestinal mucosa of horses with intestinal ischemia and reperfusion or with strangulation of the jejunum or colon. SAMPLE Mucosal samples from horses with naturally occurring strangulation (n = 24 horses) or distention (n = 6) of the jejunum or colon (11), with experimentally induced ischemia and reperfusion of the jejunum (6) or colon (15), or that were euthanized for reasons other than gastrointestinal tract disease (13). PROCEDURES Mucosal samples were collected and grouped by type of intestinal injury. Slides were stained with Luna eosinophil stain and histologically examined to determine eosinophil accumulation and distribution. Number of eosinophils per mm(2) of mucosa was calculated as a measure of eosinophil accumulation. Additionally, mucosa was categorized into 5 regions; the percentage of eosinophils in each of the 5 regions, relative to the total eosinophil count in all regions, was determined. RESULTS Eosinophil migration toward and onto the luminal surface was evident in tissues after ischemia and reperfusion and after naturally occurring strangulating disease of the jejunum and colon, as indicated by a decrease in the number of eosinophils near the muscularis mucosa and an increase in the number of eosinophils on or near the luminal surface. Ischemia alone did not change eosinophil distribution in the jejunum or colon. CONCLUSIONS AND CLINICAL RELEVANCE Eosinophils responded to mucosal damage evoked by ischemia and reperfusion by migration toward and onto the luminal surface. This migration could represent an important component of the inflammatory response to injury in equine gastrointestinal mucosa.

[Caecal volvulus after heart surgery with artificial circulation]

Presented herein is a description of a rare complication, i.e. caecal volvulus, after heart surgery. This case report illustrates difficulty of diagnosis of abdominal organs complications after artificial circulation and necessity of active surgical policy.

Gastroesophageal reflux and congenital gastrointestinal malformations

Although the outcome of newborns with surgical congenital diseases (e.g., diaphragmatic hernia; esophageal atresia; omphalocele; gastroschisis) has improved rapidly with recent advances in perinatal intensive care and surgery, infant survivors often require intensive treatment after birth, have prolonged hospitalizations, and, after discharge, may have long-term sequelae including gastro-intestinal comorbidities, above all, gastroesophageal reflux (GER). This condition involves the involuntary retrograde passage of gastric contents into the esophagus, with or without regurgitation or vomiting. It is a well-recognized condition, typical of infants, with an incidence of 85%, which usually resolves after physiological maturation of the lower esophageal sphincter and lengthening of the intra-abdominal esophagus, in the first few months after birth. Although the exact cause of abnormal esophageal function in congenital defects is not clearly understood, it has been hypothesized that common (increased intra-abdominal pressure after closure of the abdominal defect) and/or specific (e.g., motility disturbance of the upper gastrointestinal tract, damage of esophageal peristaltic pump) pathological mechanisms may play a role in the etiology of GER in patients with birth defects. Improvement of knowledge could positively impact the long-term prognosis of patients with surgical congenital diseases. The present manuscript provides a literature review focused on pathological and clinical characteristics of GER in patients who have undergone surgical treatment for congenital abdominal malformations.

[Surgical treatment of rare combination of intestinal malrotation with secondary lymphangiectasia]

The rare combination of intestinal lymphangiectasia with malrotation of the duodenum in a child of three months of life is described. Basing on the literature review only 3 similar cases were described in the world practice. The boy with protein-losing enteropathy was examined at Moscow Scientific Centre of Children's Health. The child had vomiting, diarrhea, loss in body weight, hypoproteinemia, lymphopenia. The infectious nature of the disease was excluded. It had been suggested the Waldman desease (primary intestinal lymphangiectasia). The prognosis for such disease is unfavorable. An examination of the child was continued against the backdrop of ongoing symptomatic therapy. Complete physical examination included monitoring laboratory blood tests, X-ray examination with contrast, CT-scan, gastroduodenoscopy with biopsy of the mucosa of the small intestine. Malrotation duodenum with the recurrent mid-gut volvulus with the development of secondary intestinal lymphangiectasia was diagnosed. Modern methods of examination and multidisciplinary approach made it possible to diagnose the case. Operation to eliminate fixation duodenum resulted in the recovery of the patient. At the present time the child grows and develops according to age and does not require treatment. The prognosis for this disease is regarded as favorable.

[Megacolon and sigmoid volvulus: incidence and physiopathology]

The etiology of Megacolon is multiple. One of these causes and the most frequent is Chagas disease. Its complication: sigmoid volvulus was de main diagnosis in the admitted patients at the Bolivian and Japanese Gastroenterological Institute of Cochabamba Bolivia. It usually affects people of a low economic income. In this Gastroenterological Hospital a transversal and prospective study has been done, in order to know the real incidence and the physiopathology of this disease. In a six year period, from 2000 to 2006, 8.954 patients were admitted to the Hospital: of these, 814 (9.09%), where diagnosticated as lower intestinal obstruction. In 608 (74.7%) the final diagnosis was sigmoid torsion. Radiological diagnosis was made in 84% of the patients and endoscopic decompression was successful in 88.7%. As reported in the medical literature, the main cause of megacolon in this part of the world is Chagas disease. In our investigation 22% (98 patients), were serology positive to Chagas disease, and another 21.44% (95 patients) were serology negative. They were coca leaf chewers. One of coca leaf compounds is cocaine which blocks the adrenaline and noradrenaline degradation by mean of monoamine oxidase inactivation. These two hormones stay a long term of time in the target organ: the large bowel. By this mean chronic and persistent vessel constriction develops intestinal wall atrophy and lower resistance to the intraintestinal pressure.

Mesenteric volvulus in children: two autopsy cases and review of the literature

Small bowel mesenteric volvulus when compared with mesocolonic volvulus, have not high incidence. Two autopsy cases of small bowel mesenteric volvulus in infants, highlighting the importance of a suspicion in early recognition of this rare but potentially fatal intra-abdominal emergency are reported. We also review the literature on possible aetiologies and mechanism of small bowel mesenteric volvulus, as well as its management.

Intestinal malrotations: a review and report of thirty cases

Intestinal malrotation is a developmental anomaly affecting the position and peritoneal attachments of the small and large bowels during organogenesis in foetal life. It has been defined as absent or incomplete rotation and fixation of the embryonic gut around the superior mesenteric artery. In the present paper, we review the definition, history, embryology/aetiology, epidemiology, symptoms and signs, diagnosis and treatment of intestinal malformations. Moreover, we report the records of 30 cases of malrotation admitted to our department over a period of five years. The final intraoperative diagnosis of the cases presented was 53.3% pure malrotation, 33.3% malrotation with mid-gut volvulus, 6.7% malrotation with duodenal atresia, 3.3% malrotation with Meckel's diverticulum and duodenal atresia, and 3.3% malrotation and biliary atresia. Preoperative imaging studies were performed for 27 cases and surgical management was successfully conducted without any mortality among the cases studied. This article provides an overview of basic and clinical aspects of intestinal malrotation. In addition, the signs and symptoms, imaging findings, and final intraoperative diagnoses presented by the subjects reported on are of potential use and clinical interest.

Cecal volvulus: CT findings and correlation with pathophysiology

The purpose of this study is to report the computed tomography (CT) features of cecal volvulus and to determine the accuracy of CT in distinguishing the three pathophysiological types of cecal volvulus. The CT studies of ten patients with surgically confirmed cecal volvulus were reviewed. For each patient, CT findings were looked for and recorded. The precise location of the cecum within the abdomen, the presence of an ileocecal twist, and the clockwise or counterclockwise direction of the whirl sign were specifically analyzed. All these results were confronted to the surgical diagnosis retrospectively correlated with the three types of cecal volvulus. According to our classification based on the analysis of the location of the cecum within the abdomen and the presence or the absence of a whirl sign on CT scans, the cecal volvulus was defined as the axial torsion type in four (40%) patients, loop type in four (40%) patients, and cecal bascule type in two (20%). For each patient, the result was in full accordance with the type of cecal volvulus diagnosed at surgery. CT is not only a valuable diagnostic technique in diagnosing cecal volvulus and its complications, but it is also useful in distinguishing the three pathophysiological types of cecal volvulus.

Can pulse oxymetry be used for measuring intestinal blood flow?

AIM

When studying intestinal blood flow (IBF) using radiolabeled erythrocytes in the rabbit intestinal volvulus model, we also evaluated whether a pulse oxymeter (POX) could be used for the measurement of intestinal blood flow.

METHODS

IBF was measured with radiolabeled erythrocytes and POX in the rabbit intestinal volvulus model. The study was performed on 3 groups: 1) baseline, 2) volvulus, 3) volvulus plus devolvulus.

RESULTS

The POX and scintigraphic measurements were in correlation and showed that IBF stopped for 6 hours following volvulus. IBF was significantly decreased in the volvulus plus devolvulus group compared to the baseline group (p < 0.01). IBF measured with POX correlated with scintigraphic measurements.

CONCLUSION

POX is useful for the measurement of IBF and thus may be a cheap and reliable alternative to other intestinal blood flow measurement methods.

[Cecal volvulus: anatomical bases and physiopathology]

The aim of this study was to report on 7 cases of cecal volvulus and to evaluate anatomical variations allowing this pathology.

METHODS

7 consecutive patients (4 women) treated for cecal volvulus were included. The clinical and paraclinical parameters, the management of patients, were studied through an analysis of medical histories. Contributing factors for cecal volvulus were analysed by an anatomical study and literature analysis.

RESULTS

all patients complained about abdominal pain associating or not to acute intestinal obstruction. The diagnosis was radiographically carried out for 3 patients. All patients were treated by surgical procedures (right colectomy: n = 6, cecopexy: n = 1). The mortality and morbidity rates were 0 percent and 28 percent. Fifteen anatomical subjects had complete dorsal fixation (75 percent). Seven out of them had retrocecal recessus. Five subjects (25%) had a non fixed cecum, according to the literature relating a non-fixation of ascending colon to parietal peritoneum in 11 to 25 percent of the cases. The main factor of risk is the female gender.

CONCLUSION

cecal volvulus can be advocated for patients having abdominal pain. The diagnosis is rarely based on an only clinical examination or abdominal radiographs alone. Tomodensitometry is most performing examination for diagnosis. An early and appropriate management of patients is necessary to avoid significant morbidity and mortality rates.

The changing survival scenario in gangrenous sigmoid volvulus: a four-decade study

There is a suspicion that mortality in gangrenous sigmoid volvulus has considerably declined over the recent years. This study was aimed to assess if this is a genuine trend, applicable to the patients, of this study too, and to identify factors responsible for the change, if any. Seventy-eight patients operated for gangrenous sigmoid volvulus, in the last four decades of the just gone century, were analysed. Nine clinical parameters were studied to identify factors responsible for mortality and to see if there was a change in clinical presentation in the later decades. Mortality in the 4 studied decades varied between 15.4% and 65%. Differences were significant (p<0.05) only between the decades of the seventies and eighties and between bunched pre 1980 (48%) and post 1980 (20%) decades. A sea change in survival scene occurred at the end of the decade of the seventies. The change was not accompanied by a concomitant improvement in clinical presentation (p>0.05). Two facts which could explain improved survivals in the post. 1980 period were, the increased recognition of gangrene extending beyond the area of constriction and improved survival after primary anastomoses (p<0.05). These indicated a more accurate assessment of viability and the distance between the cut bowel ends, a stricter selection of cases for primary anastomosis and using Hartmann operation in doubtful situations. Mortality in gangrenous sigmoid volvulus, without knotting in the Indian population has genuinely declined from over 50% in an earlier time to 20% in the later 20 years of the last century, the watershed in the changed scenario being the year 1980.

Sigmoid volvulus an update

Sigmoid volvulus is the third most common cause of colonic obstruction in the United States after cancer and diverticulitis. Etiologic factors include anatomic variation, chronic constipation, neurologic disease, and megacolon. Management of sigmoid volvulus involves relief of obstruction and the prevention of recurrent attacks; the outcome depends on the population and selection of patients. Although volvulus is uncommon, it may be encountered during pregnancy and is a condition that poses significant risk to both mother and fetus requiring a management strategy that varies with each trimester.

Clinics in diagnostic imaging (105): Sigmoid volvulus causing intestinal obstruction, with successful endoscopic decompression

An 89-year-old woman was admitted for intestinal obstruction. Her abdominal radiograph showed typical features of sigmoid volvulus. Decompression was done successfully through careful flexible sigmoidoscopy with minimum air insufflation. The patient's symptoms were relieved and she was discharged two days post-procedure. No recurrence was noted at extended follow-up. Rapid diagnosis and early decompression are key to optimal management of sigmoid volvulus.
