[Pneumatosis cystoides intestinalis: a case report and review of the literature]. / Pneumatosis quística intestinalis: presentación de un caso y revisión de la literatura.

Pneumatosis cystoides intestinalis features the presence of subserum or submucous cysts with gas in the intestinal wall. Its prevalence is 0.03%, although it has increased in the past decades due to a greater use of colonoscopy in everyday medical practice. Though there are several theories about its origin and many associated diseases were reported, its pathogenesis still remains uncertain. It is generally diagnosed as a finding in an imaging test. The treatment depends on the severity of the associated disease and symptoms. We report the case of a 59-year-old woman, heavy smoker, with no other clinical conditions who took a medical consultation due to abdominal bloating. She underwent a screening colonoscopy which detected the existence of cysts on the colonic wall. Afterwards, a computed tomography was performed and showed apical lung bullae, gas in a colonic wall segment, and ascitis associated to a big anexial tumor. She underwent a cytoreductive surgery, confirming the presence of advanced ovary neoplasm. The endoscopic biopsy confirmed the diagnosis of penumatosis cystoides intestinalis. We report these case because it is a rare entity which requires uncommon management and treatment guidelines.

Long-term outcome of argon plasma ablation therapy for bleeding in 100 consecutive patients with colonic angiodysplasia.

PURPOSE: Angiodysplasia is a frequent cause of colonic bleeding. Argon plasma coagulation was reported to be useful in endoscopic hemostasis. However, the long-term outcomes have been poorly evaluated. This study was designed to assess the long-term outcomes of bleeding patients with colonic angiodysplasia treated by argon plasma coagulation. METHODS: A cohort of 100 patients with gastrointestinal bleeding caused by colonic angiodysplasia was studied prospectively. The endoscopic intervention was considered successful if there was no further overt bleeding and hemoglobin concentration was stabilized (primary end point). Secondary end points were the requirement of blood transfusions, the need for surgery, bleeding-related mortality, and overall mortality. RESULTS: Overt bleeding resolved and hemoglobin levels were stabilized without transfusions or iron therapy in 85 of 100 patients (85 percent) after a median follow-up of 20 (range, 6-62) months. Transfusion requirements ceased in 90 percent of patients and only one required surgery. No patient died because of hemorrhage. In the subgroup of patients with anemia, mean hemoglobin levels increased from 9.3 (range, 5.5-12.2) g/dl before treatment to 12.6 (range, 7.4-16.7) g/dl after treatment (P < 0.01). The probability of remaining free of rebleeding at one and two year follow-up was 98 percent (95 percent confidence interval, 96-100) and 90 percent (95 percent confidence interval, 83-97), respectively. Among 118 procedures, only two complications were observed (1.7 percent). CONCLUSIONS: Endoscopic argon plasma ablation therapy is useful in the management of bleeding from colonic angiodysplasia.

Uninvestigated dyspepsia in Latin America: a population-based study.

We sought to assess the prevalence, severity of symptoms, and risk factors of uninvestigated dyspepsia in a population-based study in Argentina. Eight hundred thirty-nine valid questionnaires were evaluated. Dyspepsia was present in 367 subjects (43.2%; 95% confidence interval [CI], 39.8-46.6); 110 (13.6%) had overlap with gastroesophageal reflux disease (GERD). The group with dyspepsia without GERD consisted of 257 subjects (29.6%; 95% CI, 26.5-32.7), 183 (71.1%) had ulcer-like dyspepsia, and 74 (28.9%) had dysmotility-like dyspepsia. Symptoms were considered very severe in 1.9%, severe in 14.0%, moderate in 59.5%, and mild in 24.5% of the subjects. Dyspepsia was associated with a score >14 on the psychosomatic symptom scale (PSC) (OR, 2.52; 95% CI, 1.75-3.61), a family history of diseases of the esophagus or stomach (OR, 1.73; 95% CI, 1.19-2.52) and an educational level >12 years (OR, 1.55; 95% CI, 1.05-2.29). Dyspepsia is especially prevalent in Argentina. In a significant proportion of dyspeptic subjects, the severity of symptoms interferes with daily activities. A higher PSC, positive family history, and a higher educational level are risk factors for dyspepsia.

Argon plasma coagulation for prevention of recurrent bleeding from GI angiodysplasias.

BACKGROUND: Angiodysplasia is a frequent cause of GI bleeding. Argon plasma coagulation has been shown to arrest bleeding, but its efficacy for prevention of recurrent bleeding has not been thoroughly evaluated. This study assessed the effectiveness and the safety of argon plasma coagulation for prevention of recurrent bleeding from GI angiodysplasias. METHODS: A total of 60 patients with GI bleeding caused by angiodysplasia were included. The endoscopic intervention was considered successful if there was no further overt bleeding and if the Hb level stabilized. Recurrent bleeding was defined as any detectable bleeding episode (hematemesis, melena, or hematochezia) or a decrease in Hb level. RESULTS: Overt bleeding was resolved, and the Hb level stabilized without transfusion or supplemental iron therapy in 50 of the 60 patients (83%) at a median follow-up of 18 months (range 6-38 months). In the subgroup of patients with anemia, mean Hb level increased from 8.6 g/dL (range 5.1-12.2 g/dL) to 12 g/dL (range 8.0-15.2 g/dL) ( p < 0.01). The estimated probability of remaining free of recurrent bleeding at 1- and 2-year follow-up was 86%: 95% CI [73%, 93%] and 80%: 95% CI [64%, 89%], respectively. Among 72 procedures, only two were associated with a complication (2.8%). CONCLUSIONS: Endoscopic argon plasma coagulation is both effective and safe for prevention of recurrent bleeding from GI angiodysplasia.
