Neurosurgical experience of managing optic pathway gliomas

BackgroundOptic pathway gliomas (OPGs), also known as visual pathway gliomas, are debilitating tumors that account for 3–5% of all pediatric brain tumors. They are most commonly WHO grade 1 pilocytic astrocytomas and frequently occur in patients with neurofibromatosis type 1. The location of these tumors results in visual loss and blindness, endocrine and hypothalamic dysfunction, hydrocephalus, and premature death. Their involvement of the visual pathways and proximity to other eloquent brain structures typically precludes complete resection or optimal radiation dosing without incurring significant neurological injury. There are various surgical interventions that can be performed in relation to these lesions including biopsy, cerebrospinal fluid diversion, and partial or radical resection, but their role is a source of debate. This study catalogues our surgical experience and patient outcomes in order to support decision-making in this challenging pathology.MethodsA retrospective review of all cases of OPGs treated in a single center from July 1990 to July 2020. Data was collected on patient demographics, radiographic findings, pathology, and management including surgical interventions. Outcome data included survival, visual function, endocrine, and hypothalamic dysfunction.ResultsOne hundred twenty-one patients with OPG were identified, and 50 of these patients underwent a total of 104 surgical procedures. These included biopsy (31), subtotal or gross total resection (20 operations in 17 patients), cyst drainage (17), Ommaya reservoir insertion (9), or cerebrospinal fluid diversion (27). During the study period, there was 6% overall mortality, 18% hypothalamic dysfunction, 20% endocrine dysfunction, and 42% had some cognitive dysfunction. At diagnosis 75% of patients had good or moderate visual function in at least one eye, and overall, this improved to 83% at the end of the study period. In comparison the worst eye had good or moderate visual function in 56%, and this reduced to 53%. Baseline and final visual function were poorer in patients who had a surgical resection, but improvements in vision were still found—particularly in the best eye.Discussion/conclusionOPG are debilitating childhood tumor that have lifelong consequences in terms of visual function and endocrinopathies/hypothalamic dysfunction; this can result in substantial patient morbidity. Decisions regarding management and the role of surgery in this condition are challenging and include cerebrospinal fluid diversion, biopsy, and in highly select cases cystic decompression or surgical resection. In this paper, we review our own experience, outcomes, and surgical philosophy.

Vacuum-Assisted Closure in a Patient With Entero-Atmospheric Fistula: A Case Report

The entero-atmospheric fistula (EAF) is a recognized complication of open abdomen surgeries, which causes significant morbidity and mortality. This usually causes long hospitalizations and may require many surgical operations. While different methods of treatment for EAF are used, all different methods share the same goal, which is a proper closure of the fistula and the open abdomen to avoid recurrence and complications. We report a case of a 48-year-old female with a bowel perforation following an attempted open bilateral ovarian cyst drainage with cyst wall biopsy complicated by entero-atmospheric fistula treated by wound closure with vacuum-assisted pressure. In conclusion, the use of vacuum-assisted closure (VAC) to induce spontaneous healing of EAFs can provide a safe acceptable alternative to surgical treatment.

Endoscopic transnasal drainage for orbital implantation cyst after orbital wall reconstruction.

An implantation cyst after orbital wall reconstruction may present as a late complication, which can cause local pain, proptosis, diplopia, and vision impairment. Previous surgical strategies prefer transconjunctival or subtarsal approach for cyst drainage, a similar approach to orbital wall reconstruction. These strategies may have risk of secondary infection. Herein, we propose an endoscopic transnasal surgical approach, through which the removal of implant and cyst drainage can be performed conveniently. The residual, medial single-layer cyst wall is generally strong enough to support the orbital soft tissues without the need for a new implant. We believe this surgical approach can simplify the procedure, reduce the complications, and prevent cyst recurrence.

Application of a new drainage plug for large mandibular cysts after fenestration decompression

In order to improve the postoperative decompression and drainage of large mandibular cysts after fenestration decompression, a new drainage plug was designed and its feasibility for clinical application was explored. A total of 74 patients with large mandibular cysts requiring fenestration decompression were included and randomly divided into the control group (n=34) and model group (n=40). Patients in the control group were given a conventional plug, while patients in the model group were given the new silicone drainage plug. The drainage plug mold was printed using 3D printing technology. Subsequently, the mold was filled with silicone material and the drainage tube was placed into the mold to make a drainage plug. The clinical effect of the new drainage plug was assessed, and the postoperative recovery time was compared between the 2 groups. In the model group, the average wear time of the new drainage plug was approximately 13 months. Compared with the control group, the course of treatment in the model group was shortened by approximately 5 months, with a better fit, less food debris, and easier installation and removal. The new drainage plug provides more convenience and better prognosis for patients after fenestration decompression, and holds great promise for clinical application.

Hydatidosis and Duodenum: A Systematic Review of the Literature

Introduction: The duodenum is exceptionally affected by hydatid cyst, either primarily or secondarily (compression or fistulization from hydatid cyst located in neighboring organs). Our aim is to perform a systematic review on fistulization of hydatid cysts to the duodenum. Methods: Following PRISMA guidelines, an unlimited search on duodenal affected hydatid cyst was performed in PubMed, SCielo and EMBASE databases with no limits. Results: Fourteen papers were found, all case reports, which recorded seven men and seven women, with a mean age of 53.14 years. Three patients had recurrent hydatid cyst. The most frequent clinical manifestations were abdominal pain, and nausea and/or vomiting. In almost all cases several imaging studies were performed, but abdominal CT scan was the most used (10/14) (71%). Twelve patients had a fistula between the hydatid cyst and the duodenum, one patient had incidental paraduodenal hydatid cyst and another had severe duodenal compression from liver hydatid cyst without a fistula. Surgical treatment was performed in 12 patients; different surgical techniques were recorded in the different cases (9 conservative surgery versus 3 total cystectomy). Post-operative morbimortality is scarcely described and only one dead and 3 uneventful postoperative were reported. The follow-up period and recurrences could not be determined. Conclusions: The most common symptoms were abdominal pain, nausea and vomiting; CT scan was the most used imaging technique; and hydatid cyst drainage and fistula closure was the most appropriate treatment. All diagnostic and therapeutic options for hydatid cyst that fistulize the duodenum have a low level of evidence.

Endoscopic Transcortical Transventricular Management of Cystic Craniopharyngioma: Outcome Analysis of 32 Cases at a Tertiary Care Center.

Background:Microsurgical resection has been considered the gold standard treatment of craniopharyngioma, but lately, it has found less favor due to its morbidity and is being replaced by minimally invasive cyst drainage procedures. We present our experience of transventricular endoscopy and cyst drainage along with its technique and have analyzed its results.Materials and Methods:Clinical and radiological data of all cystic craniopharyngioma patients treated by transventricular endoscopic cyst drainage and Ommaya placement were retrieved and analyzedResults:Thirty-two patients underwent endoscopic cyst drainage during the study period. All patients had immediate clinical and radiological improvement. No significant complications were seen. All patients underwent adjuvant radiotherapy and six patients (18.7%) showed recurrence. Three patients died in the follow-up period.Conclusions:Endoscopic transcortical transventricular cyst drainage with Ommaya reservoir along with adjuvant radiotherapy is a simple, safe, and effective treatment modality.

Roux En Y drainage of a large hepatic hydatid cyst as treatment for recalcitrant bile leak: a case report

BackgroundHydatid disease is relatively uncommon in children and thus rarely reported in literature. Pediatric patients with large hydatid cysts can have grave complications due to mass effect. Postoperative bile leak is the most common morbidity and continues to be a challenge for the treating surgeon.Case presentationA 7-year-old boy diagnosed with a giant hydatid cyst of the liver, almost replacing the right lobe, and underwent a laparotomy and excision of cyst with tube drainage. He developed postoperative major bile leak which did not subside even after a redo laparotomy and closure of the suspected bile leak areas. The child underwent a third laparotomy after a hepatobiliary scintigraphy (HIDA scan) which confirmed a persisting major leak. A Roux En Y cystojejunostomy was done this time which drained the bile adequately postoperatively with no evidence of bile in the subhepatic drain. Oral feeds were resumed on the fifth postoperative day. He was discharged in a satisfactory condition and is doing well in the follow-up. Repeat HIDA scan showed no evidence of spillage, with adequate bilio-enteric drainage.ConclusionPersistent major bile leak requiring ERCP with sphincterotomy can be managed successfully in children by internal drainage as Roux En Y cystojejunostomy.

Proteus empyema as a rare complication from an infected renal cyst, a case report

BackgroundThe most commonly isolated organisms in a parapneumonic effusion include S. pneumoniae, H. influenzae, and S. aureus. If unusual organisms are isolated from the pleural space, further investigation is warranted to locate the primary source. We present a patient with an infected chronic renal cyst found to have an empyema secondary to Proteus mirabilis to highlight the importance of further diagnostic workup when encountering unusual organisms in the pleural space.Case presentationA 40-year-old African-American female, with a past medical history of asthma and sickle cell trait, presented with 5 weeks of upper respiratory tract symptoms and chest pain. A computed tomography angiogram (CTA) of the chest was negative for a pulmonary embolism but revealed a loculated left sided pleural effusion with associated left-lower lobe consolidation. She was started on empiric antibiotics, and a chest tube was inserted with drainage of frank pus. Fluid gram stain was positive for gram negative rods.Intrapleural fibrinolytics were administered for 72 h given the presence of loculations. With no improvement following fibrinolytics, she was taken to the operating room for large bore chest tube placement and left visceral pleura decortication. Pleural fluid cultures speciated to Proteus mirabilis, so further cross-sectional imaging of her abdomen/pelvis was pursued to evaluate for a primary source. A complex cystic lesion in the upper pole of the left kidney that communicated with the ipsilateral diaphragm was identified. Subsequent drainage and culture of the renal cyst was positive for Proteus mirabilis. Given clinical improvement following these interventions she was discharged with an extended course of antibiotics with plans for repeat imaging following completion of treatment.ConclusionsWhile cases of Proteus mirabilis empyema have previously been reported as a consequence of conditions such as pyelonephritis, we present, to our knowledge, the first case of a Proteus mirabilis empyema as a consequence of an infected renal cyst communicating with the pleural space. This study highlights that further evaluation with cross-sectional imaging is warranted when unusual organisms are found in the pleural space. Anatomic abnormalities that become apparent on imaging may help elucidate the source of infection.

Radiation exposure dose of fluoroscopy-guided gastrointestinal procedures: A single-center retrospective study.

Background and study aims Fluoroscopy-guided gastrointestinal procedures (FGPs) are increasingly common. However, the radiation exposure (RE) to patients undergoing FGPs is still unclear. We examined the actual RE of FGPs. Patients and methods This retrospective, single-center cohort study included consecutive FGPs, including endoscopic retrograde cholangiopancreatography (ERCP), interventional endoscopic ultrasound (EUS), enteral stenting, balloon-assisted enteroscopy, tube placement, endoscopic injection sclerotherapy (EIS), esophageal balloon dilatation and repositioning for sigmoid volvulus, from September 2012 to June 2019. We measured the air kerma (AK, mGy), dose area product (DAP, Gycm 2 ), and fluoroscopy time (FT, min) for each procedure. Results In total, 3831 patients were enrolled. Overall, 2778 ERCPs were performed. The median AK, DAP, and FT were as follows: ERCP: 109 mGy, 13.3 Gycm 2 and 10.0 min; self-expandable enteral stenting (SEMS): 62 mGy, 12.4 Gycm 2 and 10.4 min; tube placement: 40 mGy, 13.8 Gycm 2 and 11.1 min; balloon-assisted enteroscopy: 43 mGy, 22.4 Gycm 2 and 18.2 min; EUS cyst drainage (EUS-CD): 96 mGy, 18.3 Gycm 2 and 10.4 min; EIS: 36 mGy, 8.1 Gycm 2 and 4.4 min; esophageal balloon dilatation: 9 mGy, 2.2 Gycm 2 and 1.8 min; and repositioning for sigmoid volvulus: 7 mGy, 4.7 Gycm 2 and 1.6 min. Conclusion This large series reporting actual RE doses of various FGPs could serve as a reference for future prospective studies.

Actinotignum schaalii and Aerococcus urinae as Etiology of Infected Kidney Cyst: A Diagnostic Challenge

The case presented here illustrates a sometimes complex disease presentation where interdisciplinary teamwork is essential. A 74-years-old woman with stable chronic obstructive pulmonary lung disease and a composite graft aortic valve implant was admitted to hospital with an episode of acute lower back pain combined with long-term fever. The final diagnoses of a left-sided, infected and radiologically evident kidney cyst caused by the urinary tract pathogens Actinotignum schaalii and Aerococcus urinae was established by the use of partial 16S/18S rRNA gene sequence analysis on kidney cyst drainage material taken after four weeks of relevant antibiotic therapy.

Modern drainage interventions in the surgical treatment pancreatic cyst

Purpose. To evaluate the capabilities of modern minimally invasive interventions under the beam guidance in the surgical treatment of pancreatic cysts.
 Materials and Methods. The results of the examination and treatment of 88 patients with pancreatic cysts. Percutaneous puncture drainage under ultrasonographic guidance holds 56 patients, endoscopic transmural drainage of cysts by ultrasonography- in 32.
 Results. After performing percutaneous drainage of cysts positive results were observed in 42 (75,0%) patients. Relapses cystic formations were observed in 14 (25.0%) patients. Endoscopic transmural drainage under ultrasonography noted one intraoperative complication perforation of the stomach wall. 6 patients had a good result. Term follow up of patients ranged from 10 months to 3 years.
 During endoscopic transmural drainage stent dislocation and relapse of cysts were not detected in all operated patients after 6 months, Long-term results were observed only in 11 patients.
 Conclusions. Percutaneous external drainage of pancreatic cysts is an effective intervention in 75% of patients. A fairly high percentage (25%) of relapses is due to the fact that long-term external drainage do not allow to achieve complete obliteration of the cyst cavity in its connection with the main pancreatic duct and preservation of ductal hypertension of the pancreas. Endoscopic installation of a stent between the hand cavity and the lumen of the stomach allows you to create conditions for a constant outflow of cyst contents into the stomach and eliminate pancreatic hypertension. The effectiveness of internal drainage is determined by the duration of stent functioning, as well as the possibility of forming an internal cystogastric fistula (3 figs, bibliography: 8 refs).

S2352 A Tale of Two Stents: Rescue of a Migrated Lumen-Apposing Stent During EUS-Guided Cystogastrostomy

INTRODUCTION: Pancreatic pseudocysts are a common complication of pancreatitis. Both percutaneous and endoscopic therapeutic avenues have been developed for the drainage of symptomatic cysts. Surgical management is associated with higher rates of morbidity and, therefore, trans-gastric and trans-duodenal endoscopic drainage have become widely utilized treatments for the definitive management of pancreatic pseudocysts. Following tract creation and dilation, plastic pigtail stents, self-expanding metal stents, and now lumen-apposing covered self-expanding metal stents (LAMS) are used to maintain patency of the tract and allow for drainage of cysts. Though LAMS reduce the risk of stent migration, we report a case of a 28-year old female undergoing endoscopic ultrasound (EUS)-guided trans-gastric cystogastrostomy complicated by intra-procedural stent migration. CASE DESCRIPTION/METHODS: The patient had a two year history of abdominal pain that began after a cholecystectomy for gallstone disease. Computerized tomography (CT) imaging from May of 2019 demonstrated a large, thin-walled cyst within the head of the pancreas (Figure 1). The patient was scheduled to undergo EUS-guided drainage. A trans-gastric approach was utilized for tract creation. A 10 mm × 10 mm LAMS stent was deployed across the tract. The distal flange opened appropriately, however the proximal flange did not completely open. Because the tract was slightly longer than the length of the stent, while attempting to retract and reposition the stent, the proximal end migrated into the tract. To ensure maintained patency of the tract, a 10 mm × 80 mm covered metal biliary stent was placed inside of the LAMS stent to completely and securely bridge the cyst and the stomach. Final stent position was confirmed with fluoroscopy (Figure 2). The patient remained asymptomatic in the time between discharge and follow-up visit. The stents were removed without complication and no necrosis or bleeding was noted at the tract site. DISCUSSION: The use of lumen-apposing covered metal stents for pancreatic fluid collection drainage is a relatively novel technique offering a convenient, single step method of deployment. Though these large-lumen, dumbell-shaped devices reduce the risk of stent migration, we report a unique complication of the procedure in which, during stent deployment, one end of the LAMS stent migrated into the tract. Placement of a biliary metal stent proved to be an effective and safe rescue technique in this patient.Figure 1.: Large, thin-walled fluid-filled cyst in head of pancreas.Figure 2.: Fluoroscopic image demonstrating biliary metal stent contained within lumen-apposing metal stent bridging cyst to stomach.

Quiste óseo esencial: revisión de la literatura a propósito de un caso.

Simple bone cyst is a typical cavitated injury which appears between the ages of 5 and 15 and is usually located in long bones’ metaphysis. It is limited by a membrane and filled with liquid, being considered a pseudocyst. The cyst is diagnosed as a casual finding in radiological tests as well as for causing pain or pathological fractures.Different aetiologies and pathogenies are postulated, of which sine or venous blockage with increased intracameral pressure is considered to be the most probable.The traditional treatment has been surgical curing and bone filling, with new less invasive techniques such as corticosteroid injection and cyst drainage recently appearing with good results. In this article we present a large simple bone cyst at the proximal end of the femur treated by intracavity puncture of corticosteroids.

Large inflamed facial cysts in teenagers

Facial cysts can become large (1-5cm) or giant (>5cm) on the face. To describe the medical course of large and giant facial cysts in adolescents. A case series of 11 patients with large or giant facial cysts seen in an outpatient pediatric dermatology practice. Seven patients underwent incision and drainage with culture of cyst contents growing Cutibacterium acnes in six, while the seventh grew Cutibacterium acnes from a frequently worn hat. All patients were treated with traditional therapeutics for cystic acne including intralesional triamcinolone (n=9), oral antibiotics (n=10), and isotretinoin (n=1). Three patients who did not undergo cyst drainage had persistent symptomatology requiring cyst excision, whereas the seven patients whose cysts were drained (3 on initial management and 4 after recurrence) eventually had complete healing without need for surgery. Incision and drainage (I & D) and culture of cyst contents can identify cases of cysts related to Cutibacterium acnes. For some cases of large facial cysts related to Cutibacterium acne, I&D combined with conservative acne management (using standard acne guidelines) can prevent the need for surgical excision in some patients. Prospective studies are needed to determine whether this combination of therapy leads to best outcomes clinically and cosmetically.

Accuracy of C-Arm Guided Insertion of Ommaya Reservoir Tube in Recurrent Cystic Craniopharyngiomas

Abstract Background: Caniopharyngiomas in spite of being benign tumors they have a high rate of recurrence of which cysts constitute major component. Ommaya Reservoir System (ORS) is a simple manoeuvre for percutaneous drainage of cysts. Aim of Study: To evaluate the efficacy of using C-arm as a guiding tool for placement of Ommaya reservoir tube in predominantly cystic recurrent craniopharyngiomas. Patients and Methods: This study included 8 patients with clinically symptomatic and radiologically confirmed recurrent craniopharyngioma with significant cystic part. These patients were treated by C-arm guided insertion of Ommaya reservoir tube. The technique is described in details. CT brain was obtained in the first post-operative night to assess the position of the tube. Post-operative clinical and radiological evaluations were compared to the pre-operative. Results: This study included 6 males and 2 females, ranging in age from 5 years to 38 years with mean age of 18.4 years. Headache was the most common presenting complaint, followed by visual impairment. All surgeries were performed with C-arm guidance and post-operative CT brain documented satisfactory position of the tube in 7 cases and only one case required second look surgery for repositioning of the tube with the same technique. Significant post-operative improve-ment of headache and visual symptoms were encountered in all cases due to decompression of the optic chiasm by cyst drainage. Conclusion: C-arm assisted insertion of Ommaya reservoir tube is a reliable method that can minimize the errors of free hand technique and of special value in low facility centers.

Clinical outcome of arthroscopic internal drainage of popliteal cysts with or without cyst wall resection

BackgroundThis study aimed to compare the arthroscopic internal drainage of popliteal cysts alone or in combination with cyst wall resection in terms of clinical outcomes.MethodsForty-two consecutive patients with symptomatic popliteal cysts received arthroscopic treatment. Specifically, 20 of them received arthroscopic internal drainage (AI group) alone and 22 received arthroscopic internal drainage combined with cyst wall resection (AICR group) through double posteromedial portals. Magnetic resonance imaging (MRI) was performed to identify recurrence of popliteal cysts. The Lysholm score and Rauschning-Lindgren grade were used to assess the clinical outcomes. The median of the follow-up period was 24 months (12–48 months).ResultsThe two groups (AI group and AICR group) were similar in age, gender, cyst diameter, associated joint disorder, preoperative Lysholm score, preoperative Rauschning-Lindgren grade and follow-up period (P > 0.05). Relative to the AI group, the AICR group had a significantly prolonged operation time (P < 0.05) and a higher incidence of complications (P < 0.05). In both groups, the Rauschning-Lindgren grade at the last follow-up significantly differed from the preoperative grade (P < 0.05) and the Lysholm knee score remarkably increased compared to the preoperative score (P < 0.05); however, there were no differences between the two groups at the last follow-up (P > 0.05). According to the MRI results, the cyst disappeared in 11 (55%), shrank in size in 6 (30%) and existed in 3 (15%) patients in the AI group, and was absent in 18 (81.8%) and shrank in size in 4 (18.2%) patients in the AICR group, suggesting a significant difference between the two (P < 0.05).ConclusionAdditional resection of cyst wall can result in a lower recurrence rate of cysts but extend the operation time and increase the incidence of perioperative complications compared with arthroscopic internal drainage of popliteal cysts alone.

Ultrasound guided transcervical drainage of tongue base abscess.

Infected vallecular cysts should first be treated conservatively and if airway is compromised surgical treatment is considered. The aim of this study was to determine the feasibility and safety of transcervical aspiration of an infected vallecular cyst. A retrospective review of a novel technique that has been used for drainage of vallecular cyst abscesses for 5years (2012 to 2017). Galilee Medical Center affiliated to Azrieli Faculty of Medicine. Consecutive patients who underwent ultrasound guided percutaneous vallecular cyst drainage. Medical records were reviewed to identify patient characteristics, symptoms, and outcomes. During 2012-2017, seven patients underwent transcutaneous ultrasound-guided drainage of a tongue-base abscess as an in-hospital office procedure. In all patients the technique described above was feasible. About a month after the procedure, patients underwent surgical marsupialization of the cyst under general anesthesia. Ultrasound guided transcutaneous needle drainage of a base of tongue abscess is possible as it may achieve palliation and obtain material for culture. In this first-described series we show this technique's feasibility. Physicians should be familiar with this technique as it can easily be done under ultrasound guidance in the clinic using local anesthesia, and culture may be obtained, airway obstruction relieved, and recovery facilitated.

Two infant cases of intraperitoneal arterial hemorrhage due to a duplication cyst: a case report

BackgroundIntraperitoneal arterial hemorrhage without trauma is extremely rare. We report two infant cases of intraperitoneal arterial hemorrhage due to intestinal duplication.Case presentationIn case 1, a 2-month-old girl experienced sudden intraperitoneal hemorrhage from the middle colic artery with no apparent trauma. Hemostasis was achieved with suturing of the hemorrhage point, but the cause of hemorrhage was still unknown. Computed tomography after the first operation revealed a duodenal duplication cyst and a pseudopancreatic cyst. Percutaneous drainage of the pseudopancreatic cyst was performed, and the contents had high pancreatic amylase. As the size of the duodenal duplication cyst also decreased with this drainage, we suspected that the duodenal duplication cyst was connected to the pseudopancreatic cyst and the arterial hemorrhage. We hypothesized that the pancreatic juice inside the duplication cyst leaked into the intraperitoneal cavity and caused rupture of the arterial wall. Therefore, marsupialization of the duodenal duplication was performed to evacuate the pancreatic juice contained in the cyst toward the native duodenum. The postoperative course was uneventful.In case 2, a 6-month-old boy experienced sudden intraperitoneal hemorrhage without trauma. The hemorrhage site was identified as the ileocecal artery, and hemostasis was achieved with sutures. Tissue near the hemorrhage point was biopsied, because the cause of arterial wall rupture was still unknown. The biopsied tissue was found to be intestinal mucosa. The patient had recurrent abdominal pain after the first operation, and computed tomography showed a duplication cyst located near the hemorrhage point. Therefore, we resected the intestinal duplication. Pathology results showed that the intestinal duplication contained intestinal mucosa, ectopic gastric mucosa, and pancreatic tissue. The postoperative course was uneventful.ConclusionIntraperitoneal arterial hemorrhage without trauma is an extremely rare condition, and identifying its cause is difficult. To our knowledge, this is the first report of intraperitoneal arterial hemorrhage due to intestinal duplication. In cases of unexplained intraperitoneal arterial hemorrhage in infants, intestinal duplication near the hemorrhage point should be suspected.
