Surgical management of colonic basidiobolomycosis among adolescent and adult patients: presentation and outcome.

AIM: The aim of this study was to review retrospectively the clinical presentations, indications for surgery and surgical outcomes of adolescent and adult patients who were diagnosed with colonic basidiobolomycosis in the last 10 years. METHOD: The study was carried out in Aseer Central Hospital, Abha, Saudi Arabia by reviewing the medical files of all patients in the last 10 years who were diagnosed with colonic basidiobolomycosis and required surgical intervention. RESULTS: There were 22 patients. Common findings in all patients were weight loss, abdominal pain and an abdominal mass. The right colon was affected in 21 patients. The initial diagnosis was correct in seven patients while nine were thought to be malignant. All patients underwent colonic resection followed by at least 1 year of antifungal medical treatment. Intra-operatively, all patients had moderate or dense adhesions, an abdominal mass and lymphadenopathy. Most surgeons had the impression intra-operatively that the diagnosis was inflammatory rather than malignant. Postoperatively, three patients died within 6 months of the operation due to progression of the disease. Four patients developed severe wound infections, three of whom had abdominal dehiscence and required re-closure. CONCLUSION: Colonic basidiobolomycosis is a life-threatening fungal infection that should be considered a surgical condition. A high index of suspicion including basidiobolomycosis in the differential diagnosis for the acute abdomen with a colonic mass is required for a proper diagnosis. Early aggressive surgical management followed by a prolonged course of itraconazole postoperatively could improve the outcome of the condition.

[WAYS OF THE SURGICAL MISTAKES OVERCOME IN THE PAIN ABDOMINAL AND THORACIC SYNDROMS].

Experience of differential diagnosis of pleural diseases, accompanied by pleuroabdominal pain syndrome, simulating «an acute abdomen¼, was summarized. In a pleural exudate syndrome such a course was noted in 17 (3%) patients, of them 7 (1.23%) were operated on; and in a syndrome of spontaneous pneumothorax ­ in 3 (1.7%), 1 (0.4%) was operated. Diagnostic algorithm was proposed.

Pediatric Meckel's Diverticulum: Report of 208 Cases and Review of the Literature.

We report a review of 208 cases of Meckel's diverticulum among pediatric patients from one single institution. One of the aims of this report is to highlight the different diagnostic modalities of Meckel's diverticulum since a majority of cases is undiagnosed prior to surgery. Our review shows 58 cases containing gastric and/or pancreatic heterotopic tissue, including two unique cases. The first case reported is a desmoid tumor arising at the tip of diverticulum, a case that, to our knowledge, has not been previously reported. The second case involves a female patient appearing with an acute abdomen thought to be appendicitis, instead surgery revealed a diverticulum arising from the ileum. The cause of acute abdomen was due to gonococcal infection. In conclusion, we hope that this large series of Meckel's cases will enrich our readers on the differential diagnosis and preoperative diagnostic techniques of Meckels' diverticulum.

MODERN VIEWS ON THE MECHANISMS OF FORMATION AND PROSPECTS OF THERAPY OF THE PAIN ABDOMINAL SYNDROME IN PATIENTS WITH CHRONIC PANCREATITIS.

Pain in chronic pancreatitis is one of the most mysterious and complex problems of modern gastroenterology. In a review article presents current information about intrapancreatic and central mechanisms of formation of pain in patients with chronic pancreatitis. Based on the pathogenetic mechanisms outlined prospects for the treatment of patients with chronic pancreatitis with pain syndrome.

Severe acute abdomen caused by symptomatic Meckel's diverticulum in three children with trisomy 18.

Meckel's diverticulum (MD) is the most prevalent congenital anomaly of the gastrointestinal tract and often presents a diagnostic challenge. Patients with trisomy 18 frequently have MD, but the poor prognosis and lack of consensus regarding management for neonates has meant that precise information on the clinical manifestations in infants and children with MD is lacking. We describe the cases of three children with trisomy 18 who developed symptomatic MD. Intussusception was diagnosed in Patient 1, intestinal volvulus in Patient 2, and gastrointestinal bleeding in Patient 3. All three patients underwent surgical treatment and only the Patient 1 died due to pulmonary hypertensive crisis. The other two patients experienced no further episodes of abdominal symptoms. In patients with trisomy 18, although consideration of postoperative complications and prognosis after surgical treatment is necessary, symptomatic MD should carry a high index of suspicion in patients presenting with acute abdomen.

Epiploic Appendagitis: A Rare Cause of Acute Abdominal Pain in Children. Report of a Case and Review of the Pediatric Literature.

A 9-year-old boy presented with acute onset of abdominal pain and vomiting. History, physical examination, and initial laboratory testing failed to provide a diagnosis. A computed tomography scan revealed the rare finding of epiploic appendagitis. We review the literature of this rare, but increasingly recognized, condition that mimics appendicitis and needs to be considered in the child with acute abdominal pain.

Segmental absence of intestinal musculature -presentation in a 10-year-old boy with an extensive involved segment.

Segmental absence of the intestinal musculature is a rare cause of acute abdomen most likely associated with intestinal perforation and sepsis in neonates and adults. We present a case of a 10-year-old boy who developed acute abdomen and was treated with right hemicolectomy and partial resection of the ileum. The ileum showed a 20-cm-long stenotic segment showing prominent thinning of the intestinal wall. This case occurred in an older child, which appears to be rare when comparing the literature. The bowel defect was also the largest described to date, indicating the potential effect of an atonic segment leading to obstructive disease.

[Risk Factors for Poor Prognosis after Emergency Surgery for Acute Abdomen].

BACKGROUND: Risk factors associated with poor outcome were investigated in patients receiving emergency surgery. METHODS: Patients' characteristics, surgical information, postoperative complication and 30-days mortality were reviewed in 226 adult consecutive patients undergoing emergency abdominal surgery. Postoperative complication was defined as surgical site infection, anastomotic leakage, intraperitoneal abscess and formation or requirement of renal replacement therapy. Multivariate logistic regression was performed to identify the parameters associated with 30-day mortality and postoperative complication. RESULTS: Mortality rate was 7.1%. Complication occurred in 41.2%. Multivariate logistic regression revealed surgical Apgar score (SAS) as independent predictor of the death. SAS, duration of the surgery and preoperative SOFA were identified as independent predictors of the complication. CONCLUSIONS: SAS and preoperative SOFA are useful to predict poor prognosis after emergency surgery due to acute abdomen.

Perigastric appendagitis: CT and clinical features in eight patients.

AIM: To describe perigastric appendagitis (PA) on CT as a new and distinct clinical entity to enable recognition and prevent additional unnecessary investigation or intervention. MATERIALS AND METHODS: Institutional review board approval was obtained and informed consent was waived. Retrospective review of the clinical data and CT findings in eight patients with PA encountered over 10 years at one institution was performed. The English literature was reviewed and summarized. Two experienced abdominal radiologists reviewed the CT images by consensus. RESULTS: Seven of eight patients had moderate to severe epigastric pain for 1­7 days. All eight patients (four men, four women; mean age 44 years, range 33­81 years) had no fever or leukocytosis. All underwent abdominal CT which showed ovoid fat inflammation along the course of the perigastric ligaments (gastrohepatic, gastrosplenic, and falciform). Two had gastric wall thickening. Although the inflammation was correctly described, the specific diagnosis was not made on initial interpretation in five patients. Subsequently, they underwent further diagnostic testing [an upper gastrointestinal examination and hepatobiliary iminodiacetic acid (HIDA) cholescintigraphy, an upper endoscopy and MRI examination, HIDA cholescintigraphy, another CT, and an MRI examination, respectively]. The HIDA cholescintigraphy, upper GI examination, and upper endoscopy examinations were normal. No repeated examination was performed on the other three patients. Pain resolved spontaneously in all within two days. CONCLUSION: Perigastric appendagitis can present with an acute abdomen, which is safely managed conservatively if diagnosed correctly. Radiologists should be aware of the entity to avoid unnecessary intervention, and recognize the CT findings of ovoid fat inflammation in the distribution of the perigastric ligaments.

[Acute abdomen in children: a continuous challenge. Two cases report: Meckel's diverticulum with small bowel volvolus and internal herniation related to epiploic appendagitis mimicking acute appendicitis]. / Addome acuto in età pediatrica: una sfida continua. Due casi clinici: volvolo intestinale su residue del dotto onfalo mesenterico e strangolamento ileale su appendice epiploica cecale.

Acute abdomen is a continuous clinical challenge in pediatric age. The aim of our study is to describe two pediatric rare cases: the first case is a small bowel volvolus related to Meckel's diverticulum confused with an intestinal intussusception; the second an internal herniation related to epiploic appendagitis with intestinal obstruction mimic acute appendicitis in two years old children. We review the current literature.

Lassa fever presenting as acute abdomen: a case series.

Lassa fever, an endemic zoonotic viral infection in West Africa, presents with varied symptoms including fever, vomiting, retrosternal pain, abdominal pain, sore-throat, mucosal bleeding, seizures and coma. When fever and abdominal pain are the main presenting symptoms, and a diagnosis of acute abdomen is entertained, Lassa fever is rarely considered in the differential diagnosis, even in endemic areas. Rather the diagnosis of Lassa fever is suspected only after surgical intervention. Therefore, such patients often undergo unnecessary surgery with resultant delay in the commencement of ribavirin therapy. This increases morbidity and mortality and the risk of nosocomial transmission to hospital staff. We report 7 patients aged between 17 months and 40 years who had operative intervention for suspected appendicitis, perforated typhoid ileitis, intussuception and ruptured ectopic pregnancy after routine investigations. All seven were post-operatively confirmed as Lassa fever cases. Four patients died postoperatively, most before commencement of ribavirin, while the other three patients eventually recovered with appropriate antibiotic treatment including intravenous ribavirin. Surgeons working in West Africa should include Lassa fever in the differential diagnosis of acute abdomen, especially appendicitis. The presence of high grade fever, proteinuria and thrombocytopenia in patients with acute abdomen should heighten the suspicion of Lassa fever. Prolonged intra-operative bleeding should not only raise suspicion of the disease but also serve to initiate precautions to prevent nosocomial transmission.

Acute abdomen due to ovarian congestion: a fallopian tube accompanied by a paratubal cyst, coiling tightly round the ovary.

We experienced an unreported rare case with an adnexal mass causing severe acute abdomen during pregnancy. A 30-year-old Japanese pregnant woman was transported to our hospital for her right lower abdominal pain at 30 weeks of gestation. Magnetic resonance imaging and ultrasound demonstrated a cyst measuring 3-4 cm in diameter adjacent to the right ovary, and a parovarian cyst was considered to be the most probable diagnosis. We strongly suspected torsion of the ovarian pedicle or fallopian tube in conjunction with her clinical symptoms. Laparotomy revealed that the elongated right fallopian tube accompanied by a paratubal cyst was coiling tightly 2.5 times round the right ovary, causing apparent congestion and enlargement of the right ovary. Soon after we released the congested right ovary from the coiling of the fallopian tube, the congestion subsided. The postoperative course was favorable, and pregnancy and delivery were uneventful.

Comparison between survey radiography, B-mode ultrasonography, contrast-enhanced ultrasonography and contrast-enhanced multi-detector computed tomography findings in dogs with acute abdominal signs.

Contrast-enhanced multi-detector computed tomography (CE-MDCT) is used routinely in evaluating human patients with acute abdominal symptoms. Contrast-enhanced ultrasound (CEUS) continues to be in its infancy as it relates to evaluation of the acute abdomen. The purpose of this study was to compare survey radiography, B-mode ultrasound, CEUS, and CE-MDCT findings in canine patients presenting with acute abdominal signs; with a focus on the ability to differentiate surgical from non-surgical conditions. Nineteen dogs were prospectively enrolled. Inclusion required a clinical diagnosis of acute abdominal signs and confirmed surgical or non-surgical causes for the clinical signs. Agreement for the majority of recorded imaging features was at least moderate. There was poor agreement in the identification of pneumoperitoneum and in the comparison of pancreatic lesion dimensions for B-mode vs. CEUS. The CT feature of fat stranding was detected in cases including, but not limited to, gastric neoplasia with perforation, pancreatitis, and small intestinal foreign body. Ultrasound underestimated the size and number of specific lesions when compared with CE-MDCT. Contrast-enhanced ultrasound was successful in detecting bowel and pancreatic perfusion deficits that CE-MDCT failed to identify. Accuracy for differentiation of surgical vs. non-surgical conditions was high for all modalities; 100%, 94%, and 94% for CE-MDCT, ultrasonography and survey radiography respectively. Findings indicated that CE-MDCT is an accurate screening test for differentiating surgical from non-surgical acute abdominal conditions in dogs. Focused CEUS following CE-MDCT or B-mode ultrasonography may be beneficial for identifying potentially significant hypoperfused lesions.

Bilateral Morgagni hernia: operative discovery of appendix lying on superior pulmonary vein.

A patient presented having an acute abdomen on a background of a twelve-month history of worsening asthma. Computed tomography showed giant bilateral intrathoracic hernias extending to both thoracic apices. Our case was unusual as the defect was bilateral and left-sided. Surgical repair revealed each hernia sac measuring >20 cm and to contain the entirety of the small bowel and colon (including retroperitoneal bowel). The appendix was discovered adjacent to right superior pulmonary vein. Both sacs were excised and the defects dissected and transfixed in a single stage operation. In the post-operative stage, he developed a 6.3 cm fluid collection anterior to the right atrium and a left-sided pleural effusion. Morgagni hernias can escape detection and be attributed to other diagnoses courtesy of false localising signs on clinical examination and symptoms in the history.

Is familial Mediterranean fever (FMF) common in patients with negative appendectomy?

OBJECTIVES: Familial Mediterranean fever (FMF) is an autosomal-recessive disease characterized by recurrent attacks of fever with serositis. Differential diagnosis of a FMF abdominal attack with acute abdomen is difficult. Acute appendicitis is the most common cause of acute abdominal pain that requires surgical treatment. The aim of this study was to investigate frequency of FMF in patients with negative appendectomy. METHODS: We assessed 278 patients (female/male 127/151) who were operated with preoperative diagnosis of acute appendicitis. In 250 of the patients, definitive diagnosis of acute appendicitis was established by histo-pathological examination. Patients with negative appendectomy were assessed for FMF by rheumatologist. RESULTS: Negative appendectomy was detected in 28 patients (M/F 5/23, mean age 25.3 ± 8.4 years). Negative appendectomy ratio was 10.1 %. Among 28 patients two had FMF (7.7 %). CONCLUSIONS: FMF were established in 7.7 % of patients with negative appendectomy. Our study suggests patients having negative appendectomy should be evaluated for FMF. Further large sample studies are needed to define the real prevalence of FMF among negative appendectomy patients.

Primary epiploic appendagitis and successful outpatient management.

BACKGROUND: Primary epiploic appendagitis (PEA) is a rare cause of abdominal acute or subacute complaints. Diagnosis of PEA is made with ultrasonography (US) or when computed tomography (CT) reveals a characteristic lesion. CASE REPORT: We report on two patients with PEA. In one patient PEA was first seen with US and confirmed with contrast enhanced CT, and in the second patient CT without contrast enhancement demonstrated PEA. In both patients an outpatient recovery with conservative non-surgical treatment is described. CONCLUSIONS: Medical personnel should be aware of this rare disease, which mimics many other intra-abdominal acute and subacute conditions. A correct diagnosis of PEA with imaging procedures enables conservative and successful outpatient management avoiding unnecessary surgical intervention and additional costs.

Enterocolic lymphocytic phlebitis: an unusual cause of abdominal complaints.

Enterocolic lymphocytic phlebitis (ELP) is a rare disease of unknown etiology involving most often the intramural and mesenteric small and medium-sized veins of the gastrointestinal tract. The diagnosis of the disorder is based on the histopathological examination of a surgical specimen as endoscopically obtained diagnostic material is usually too superficial. Clinical manifestation of ELP most frequently is characterized by acute symptoms, such as acute abdomen, signs suggesting acute appendicitis, gastrointestinal hemorrhage, sometimes it manifests as chronic gastrointestinal complaints. We report, to our knowledge for the first time in Poland, a case of ELP with clinical symptoms pointing to acute appendicitis, on laparoscopy manifesting as a tumorous mass in the colonic wall with an unchanged appendix.

Ruptured mucinous cystic neoplasm with an associated invasive carcinoma of pancreatic head in a pregnant woman: report of a case and review of literature.

Mucinous cystic neoplasm (MCN) of the pancreas is characterized by mucin-producing columnar epithelium and an ovarian-type stroma. It occurs almost exclusively in women and is almost always located in the pancreatic body or tail. Here, we report a case of large MCN located in the pancreatic head but not in the body nor tail in a 32-year-old pregnant woman, which was thought to have grown rapidly during pregnancy. It was ruptured at 34 weeks of gestation and the patient was admitted to the emergency department of the University of Fukui Hospital with an acute abdomen. Emergency cesarean section followed by pancreaticoduodenectomy was performed. The tumor consisted of many small cysts lined by a single-layer of mucinous epithelium with papillary growth and partial solid parts showing invasive growth and sarcomatoid changes, indicating mucinous cystic neoplasm with an associated invasive carcinoma (previously referred as mucinous cystadenocarcinoma). Thickened septa revealed ovarian-type stroma strongly positive for α-inhibin and partly positive for progesterone receptor immunohistochemically. We also review and discuss previous reports of MCNs including those with an associated invasive carcinoma in pregnant patients.

Misty mesentery: a pictorial review of multidetector-row CT findings.

The term "misty mesentery" indicates a pathological increase in mesenteric fat attenuation at computed tomography (CT). It is frequently observed on multidetector CT (MDCT) scans performed during daily clinical practice and may be caused by various pathological conditions, including oedema, inflammation, haemorrhage, neoplastic infiltration or sclerosing mesenteritis. In patients suffering from acute abdominal disease, misty mesentery may be considered a feature of the underlying disease. Otherwise, it may represent an incidental finding on MDCT performed for other reasons. This article describes the MDCT features of misty mesentery in different diseases in order to provide a rational approach to the differential diagnosis.
