Pylorus preserving pancreatoduodenectomy in a 6-year-old girl with recurrent pancreatitis due to an annular pancreas

AbstractThe pancreatitis caused by an annular pancreas rarely needs a surgical management in children. Here, we report a case of a 6-year old girl in whom pylorus-preserving pancreatoduodenectomy (PPPD) was performed for the pancreatitis caused by an annular pancreas. As she had previous operations for duodenal atresia and pancreaticobiliary maljunction, PPPD was chosen as a definitive surgical treatment of annular pancreas. She has been free from symptoms for 2 years after the operation

Treatment and follow-up of late onset intra hepatic bile duct stones in congenital biliary dilatation

This version of the article has been accepted for publication, after peer review (when applicable) and is subject to Springer Nature’s AM terms of use, but is not the Version of Record and does not reflect post-acceptance improvements, or any corrections. The Version of Record is available online at: https://doi.org/10.1007/s00383-022-05321-w.Purpose: The postoperative course after surgery for congenital biliary dilatation (CBD) has some complications. Intrahepatic bile duct (IHBD) stones were known as a late complication. We report on the treatment and long-term follow-up of postoperative IHBD stones in our department. Methods: Patients who underwent CBD surgery at age 15 years or younger in our department were identified. Those followed up for 5 years or more were enrolled. Annual blood chemistry tests and abdominal ultrasonography were performed. Each patient’s surgical procedure, IHBD stone diagnosis, treatments, and outcomes were retrospectively assessed. Results: Fifty-one patients were analyzed. The median age at the last visit was 24 years (range 7–45 years), and the median age at CBD surgery was 3 years. Eight patients (16%) developed late-onset IHBD stones. The median age at onset was 25 years, and the median duration after surgery was 20 years. The initial treatment was double-balloon enteroscopy (DBE) in 4 cases, which resulted in stone removal in 3 of the 4 patients (75%). Conclusion: Since CBD may cause late-onset IHBD stones, continuous follow-up is required even in adulthood. In this study, DBE was effective and minimally invasive, and it is recommended as the initial treatment

Torsion of Meckel’s Diverticulum in a Child

Meckel’s diverticulum (MD) is a common congenital anomaly of the gastrointestinal tract, the majority of cases of which are clinically silent. Patients with asymptomatic MD can unexpectedly develop acute abdominal pain. Making a diagnosis of MD is often difficult due to the lack of specific symptoms caused by this condition. Diagnostic laparotomy can be useful for making an accurate and prompt diagnosis of complicated MD. We herein describe a pediatric case of torsion of a MD in whom we performed laparoscopic-assisted emergency surgery. The patient was an 11-year-old male who developed sudden severe right lower abdominal pain. Clinical and laboratory findings were suggestive of appendicitis, however computed tomography scans showed a large cystic mass in the pelvis. Exploratory laparoscopy led to a diagnosis of torsion of a MD, and wedge resection of the gangrenous MD was performed through an umbilical port incision. The patient’s postoperative course was uneventful. We conclude that diagnostic laparoscopy followed by laparoscopy-assisted Meckel’s diverticulectomy via an umbilical incision is useful in the treatment of acute abdomen caused by MD

Congenital Treves' field transmesenteric hernia in children: A case series and literature review

Transmesenteric hernia is abdominal visceral herniation through a congenital or acquired mesenteric defect. Treves' field is the area of terminal ileal mesentery circumscribed by the ileocolic artery and its last ileal branch. It is very susceptible to congenital defects. To clarify the clinical course of congenital Treves' field transmesenteric hernia (cTFTH), we retrospectively reviewed pediatric cases and conducted a literature review. Five consecutive pediatric cTFTH cases (one male, four females) underwent emergency laparotomy at our institutions from April 2009 and December 2014. We analyzed their demographics, preoperative findings, surgical procedures, and outcomes, along with a literature review. Abdominal plain X-ray showed displaced intestinal gas with gas paucity in the center of the abdomen in two cases and diffusely increased intestinal gas in two others. Abdominal computed tomography (CT) in four cases showed intestinal loop clusters, mesenteric vessel changes, small-bowel obstruction, and ascites. All cases underwent emergency laparotomy for ileal resection with ileocecal valve preservation. Simultaneous anastomoses were performed in four cases; the remaining case underwent ileostomy because of prematurity. Although one case needed reoperation for postoperative bowel obstruction, all patients survived. Literature review of pediatric cTFTH showed a high frequency of necrosis (70.5%) and mortality (26.5%). Among pediatric cTFTH cases, 67.6% were aged <5 years. Mesenteric defect was <5 cm in 70% cases. We should be aware of the clinical importance and radiological features of pediatric cTFTH. Abdominal CT may provide useful information

Glutamine Prevents Total Parenteral Nutrition-Associated Changes to Intraepithelial Lymphocyte Phenotype and Function: A Potential Mechanism for the Preservation of Epithelial Barrier Function

Total parenteral nutrition (TPN) results in a number of derangements to the intestinal epithelium, including a loss of epithelial barrier function (EBF). As TPN supplemented with glutamine has been thought to prevent this loss, this article further defined the impact of glutamine on EBF, and investigated potential mechanisms that contributed to the preservation of EBF. C57BL/6J male mice were randomized to enteral nutrition (control), TPN, or TPN supplemented with glutamine (TPN+GLN). Changes in intraepithelial lymphocyte (IEL)-derived cytokine expression were measured, and EBF was assessed with electrophysiologic methods and assessment of junctional protein expression. TPN resulted in a significant decline in EBF, and this loss of EBF was significantly prevented in the TPN+GLN group. Coincident with these changes was a loss of intraepithelial lymphocyte (IEL, mucosal lymphocyte)-derived IL-10 and increase in interferon-? (IFN-?) expression, and a decline in IEL numbers in the TPN group. A prevention in the increase in IFN-? and decline in IL-10 expression was seen in the TPN+GLN group. To determine the mechanism responsible for these glutamine-associated cytokine changes, we tested whether blockade of the IL-7 signaling pathway between epithelial cells (EC) and IEL would prevent these changes; however, blockade failed to influence IEL-derived cytokine changes. Glutamine-supplemented TPN leads to a specific IEL-derived cytokine profile, which may account for the preservation of EBF; and such action may be due to a direct action of glutamine on the IEL.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/85114/1/jir_2009_0046.pd

Massive Ascites in a Renal Transplant Patient after Laparoscopic Fenestration of a Lymphocele

Retroperitoneal lymphocele is a common complication of renal transplantation. Here, we report the case of a 67-year-old woman with massive ascites after fenestration surgery for a lymphocele that developed following renal transplantation. She had been on continuous ambulatory peritoneal dialysis for 9 years. Living donor renal transplantation was performed and an intrapelvic lymphocele subsequently developed. The lymphocele did not resolve after aspiration therapy; therefore, laparoscopic fenestration was performed. Although the lymphocele disappeared, massive ascites appeared in its stead. Half a year later, the ascites was surgically punctured, which then gradually resolved and disappeared 6 weeks later. Aspiration therapy should be considered in patients on long-term peritoneal dialysis, although laparoscopic fenestration is safe and effective
