Hemoperitoneum after transperineal prostate biopsy.

Bleeding is the most common complication after a prostate biopsy, commonly self-limited. We describe a case of a patient who developed a hemoperitoneum after a transperineal prostate biopsy. A 65-year-old man with a history of prostate cancer diagnosed in 2016 by transurethral resection, with no further urologic control until 2020 when a rise in the serum prostate-specific antigen was diagnosed: 4.49 ng/ml. Prostate digital rectal examination had no pathologic findings. Magnetic resonance imaging informed anequivocal lesion. A target transperineal fusion biopsy was performed, guided by ultrasound (US). Pre-surgical blood tests, including coagulogram, were normal. No immediate postoperative complications were recorded, and the patient was discharged. Hours later, he returned after a head concussion due to orthostatic hypotension and diffuse abdominal pain. Blood test showed a drop in hematocrit and hemoglobin values. Abdominal US and abdominopelvic computed tomography scan showed free intraperitoneal fluid and intraperitoneal hematic collection on top of the bladder of 104 × 86 mm with no active bleeding. The patient was admitted to intensive care unit due to persistent hypotension despite fluid restoration. He received a single-unit blood transfusion and had a good response to vasopressors. Abdominal pain decreased. He was finally discharged with stable hematocrit 48hours after admission. Clinical management with no surgery or radiologic angio-embolization was required. We found no clear origin of the intraperitoneal bleeding, but we hypothesize that maybe the previous transurethral resection of the prostate made anatomical changes that facilitated blood passage to the abdominal cavity after puncture of branches from the inferior vesical artery.

La complicación más frecuente tras una biopsia prostática es el sangrado, generalmente autolimitado. Aquí describimos un caso de hemoperitoneo secundario a dicho procedimiento. Hombre de 65 años con antecedentes de cáncer de próstata diagnosticado en 2016 por una resección transuretral de próstata, sin seguimiento urológico, consultó en 2020 por aumento del antígeno prostático específico: 4.49 ng/ml, asociado a tacto rectal normal y una resonancia multiparamétrica de próstata mostró una lesión indeterminada. Se realizó una biopsia prostática transperineal por fusión guiado por ecografía. Los análisis preoperatorios, incluido coagulograma, eran normales. No se registraron complicaciones intraquirúrgicas y se indicó el alta. Horas más tarde, consultó al hospital por hipotensión ortostática y dolor abdominal difuso. Los análisis demostraron caída del hematocrito y hemoglobina. Una ecografía y posterior tomografía computada evidenciaron una colección supravesical de 104 × 86mm sin signos de sangrado activo. Se indicó internación en sala de cuidados intensivos debido a hipotensión refractaria a expansiones con requerimiento de vasopresores. Recibió una transfusión de glóbulos rojos. Por favorable evolución, 48 horas después del ingreso recibió el alta. En este caso, fue posible un manejo conservador, sin requerimiento de cirugía o embolización. Si bien no se encontró sitio exacto del sangrado, creemos que la resección transuretral previa podría haber generado cambios anatómicos que facilitaran el pasaje de sangre, posiblemente proveniente de ramas de la arteria vesical inferior a cavidad abdominal luego de la punción.

Therapeutic Response for Functional Abdominal Pain in Children with Occult Constipation: Laxatives versus Prokinetic Drugs.

The relationship between functional abdominal pain (FAP) and occult constipation (OC) in children who did not meet the Rome III criteria for constipation has rarely been reported. This study aimed to estimate the prevalence of OC in patients with FAP and to compare the effectiveness of prokinetic drugs and laxatives for FAP and OC. Pediatric outpatients (n = 212; aged 4-15 years) who satisfied the Rome III criteria for childhood FAP were divided into 2 groups based on Leech scores: group 1 < 8; group 2 ≥ 8. Group 2 received either prokinetic drugs or laxatives and pain severity was assessed after 2 weeks, 1 month, and 3 months. A total 52.4% (111/212) of patients had OC in this study. More patients who received laxatives had reduced pain scores compared with those who received prokinetic drugs. Those treated with laxatives in group 2 had a better response than those treated with prokinetic drugs throughout the study period (P < 0.001, P < 0.001, and P = 0.002 after 2 weeks, 1 month, and 3 months, respectively). OC was frequently encountered in children with FAP. Laxatives can be more effective than prokinetic drugs for relieving symptoms of FAP in children with a Leech score ≥ 8 and suspected OC.

The efficacy of Shugan Jianpi Zhixie therapy for diarrhea-predominant irritable bowel syndrome: a meta-analysis of randomized, double-blind, placebo-controlled trials.

BACKGROUND: Shugan Jianpi Zhixie therapy (SJZT) has been widely used to treat diarrhea-predominant irritable bowel syndrome (IBS-D), but the results are still controversial. A meta-analysis of randomized, double-blind, placebo-controlled trials was performed to assess the efficacy and tolerability of SJZT for IBS-D. METHODS: The MEDLINE, EMBASE, Cochrane Library, the China National Knowledge Infrastructure database, the Chinese Biomedical Literature database and the Wanfang database were searched up to June 2014 with no language restrictions. Summary estimates, including 95% confidence intervals (CI), were calculated for global symptom improvement, abdominal pain improvement, and Symptom Severity Scale (BSS) score. RESULTS: Seven trials (N=954) were included. The overall risk of bias assessment was low. SJZT showed significant improvement for global symptom compared to placebo (RR 1.61; 95% CI 1.24, 2.10; P =0.0004; therapeutic gain = 33.0%; number needed to treat (NNT) = 3.0). SJZT was significantly more likely to reduce overall BSS score (SMD -0.67; 95% CI -0.94, -0.40; P < 0.00001) and improve abdominal pain (RR 4.34; 95% CI 2.64, 7.14; P < 0.00001) than placebo. The adverse events of SJZT were no different from those of placebo. CONCLUSIONS: This meta-analysis suggests that SJZT is an effective and safe therapy option for patients with IBS-D. However, due to the high clinical heterogeneity and small sample size of the included trials, further standardized preparation, large-scale and rigorously designed trials are needed.

Incidental detection of ascariasis worms on USG in a protein energy malnourished (PEM) child with abdominal pain.

A 10-year-old child presented with dull aching periumbilical abdominal pain for 15 days. The child was not gaining weight despite a good appetite. Physical examination of the child revealed grade-I protein energy malnourishment (PEM) according to IAP (Indian Academic of Paediatrics) classification. The rest of the systemic examination was normal. Routine blood investigation revealed anaemia with eosinophilia. Abdominal ultrasonography did not show any abnormality with curvilinear transducer (3.5-5 MHz), however, linear ultrasound transducer (7.5-12 MHz) with harmonic tissue imaging showed worms in the lumen of the small intestine with curling movement on real time scanning. Stool examination for the eggs of ascariasis was positive. The patient was treated with antihelminthic drugs. Dietary modification for the PEM was advised. After 3 months of treatment, the patient improved and stool examination for Ascaris was negative on follow-up.

Gastric electrical stimulation for abdominal pain in patients with symptoms of gastroparesis.

Abdominal pain physiology may be better understood studying electrophysiology, histology, and symptom scores in patients with the symptoms of gastroparesis (Gp) treated with gastric electrical stimulation (GES). Ninety-five Gp patients' symptoms were recorded at baseline and during temporary and permanent GES. Gastric-emptying times and cutaneous, mucosal, and serosal electrogastrograms were obtained. S100-stained, full-thickness gastric biopsies were compared with autopsy controls. Sixty-eight patients reported severe pain at baseline. Severe pain patients' mean pain scores decreased with temporary GES from 3.62 to 1.29 (P < 0.001) and nonsevere pain from 1.26 to 0.67 (P = 0.01). With permanent GES, severe mean pain scores fell to 2.30 (P < 0.001); nonsevere pain changed to 1.60 (P = 0.221). Mean follow-up was 275 days. Mean cutaneous, mucosal, and serosal frequencies and frequency-to-amplitude ratios were markedly higher than literature controls. For patients with Gp overall and subdivided by etiology and severity of pain, S-100 neuronal fibers were significantly reduced in both muscularis propria layers. GES improved severe pain associated with symptoms of Gp. This severe pain is associated with abnormal electrogastrographic activity and loss of S100 neuronal fibers in the stomach's inner and outer muscularis propria and, therefore, could be the result of gastric neuropathy.

Myofascial pain syndrome in the differential diagnosis of chronic abdominal pain.

Myofascial pain syndrome is a painful musculoskeletal condition, and a quite common cause of chronic pain. It is characterized by the development of trigger points that are locally tender when active, and refer pain through specific patterns to other areas of the body. Its etiological factors are various; trauma, vertebral column diseases, systemic disorders, psychological distress, lack of motion, and chilling of the body parts. Myofascial pain syndrome may be misdiagnosed as arising from a visceral source especially if its probability is not kept in mind and a proper patient examination is lacking. Although there are many therapeutic approaches, trigger point injections can be diagnostic and therapeutic.

Radiologic findings of Behçet syndrome involving the gastrointestinal tract.

Behçet syndrome is characterized by the histopathologic finding of nonspecific vasculitis in multiple organs. The diagnosis is usually made on the basis of the combination of clinical signs and symptoms. This disease involves the gastrointestinal tract in 10%-50% of patients, and the terminal ileum and cecum are chiefly affected. Barium study is useful in demonstrating the characteristic radiographic features of Behçet syndrome involving the gastrointestinal tract. The presence of deep, penetrating ulcers results in a high rate of complications, such as perforation, fistula, hemorrhage, and peritonitis. Furthermore, recurrence of disease adjacent to or at the surgical anastomosis is common. Computed tomography is useful in determining the extent of the lesions and in identifying cases in which complications are likely to occur. Familiarity with the various radiologic findings of Behçet syndrome involving the gastrointestinal tract helps in making an early diagnosis, as well as in establishing an appropriate treatment strategy.
