Gastrointestinal bleeding as a complication of serial transverse enteroplasty

Clinical characteristics and management of reoperation for high jejunal atresia: a retrospective study

OBJECTIVE

To analyze the clinical characteristics and available treatment strategies for reoperation of neonatal high jejunal atresia, and recommend preventive measures to reduce the reoperation rate of high jejunal atresia.

METHODS

The clinical data of 16 children with high jejunal atresia who underwent reoperation in the Neonatal Surgery Department at Children's Hospital of Zhejiang University School of Medicine from January 2018 to January 2023 were retrospectively analyzed.

RESULTS

Among the 16 unplanned reoperations, 7 (43.6%) were performed for functional ileus, 3 (18.8%) for anastomotic stenosis, 3 (18.8%) for adhesive ileus, and 3 (18.8%) for postoperative proximal septum. Surgical procedures for reoperations include duodenoplasty, resection and re-anastomosis of the original anastomosis, resection of the duodenal septum and enterolysis. Among the 16 patients, 1 had short-bowel syndrome that required repeated hospital admission for parenteral nutrition treatment, and 1 patient died of recurrent pneumonia and heart failure after surgery. The other 14 patients recovered from reoperation and were discharged. The patients were followed up from 1 month to 5 years after surgery, and showed good growth.

CONCLUSION

For children with high jejunal atresia, the operative procedure will vary according to each patient's circumstances. If postoperative functional obstruction occurs, a wider range of bowel cutting and re-anastomosis can be performed. During the first operation, the diaphragm at the proximal end of jejunal atresia should not be missed.

Surgical considerations in the management of short bowel syndrome

Patients with short bowel syndrome (SBS) are optimally managed in centers of expertise with dedicated multidisciplinary intestinal failure (IF) teams. Over the life of a patient with SBS, many different surgical concerns may arise requiring intervention. These can range from reasonably simple procedures, such as the creation or maintenance of gastrostomy tube and enterostomies, to complex reconstructions of multiple enterocutaneous fistulas or the performance of intestine-containing transplants. This review will cover the development of a surgeon's role on the IF team; common surgical issues arising in patients with SBS, with a focus on decision-making rather than technique; and, finally, a brief overview of transplantation and some related decision-making issues.

Successful treatment of Henoch-Schönlein purpura-associated hematochezia in a child with hemophilia A: a case report

BACKGROUND

Henoch-Schönlein purpura (HSP) is a common form of immunological vasculitis in children. Hemophilia A is a genetic disorder and characterized by spontaneous hemorrhage or prolonged bleeding due to factor VIII deficiency. Both diseases increase the risk of bleeding, but they have different mechanisms. How should we treat patients with both diseases?

CASE PRESENTATION

An 8-year-old male with hemophilia A was diagnosed with HSP while receiving coagulation factor VIII replacement therapy in our hospital. Hematochezia occurred 6 days after the diagnosis of HSP. And he treated with coagulation FVIII, methylprednisolone and hemostatic drugs.

CONCLUSIONS

There is no causal relationship between hemophilia A and HSP, but both diseases can cause bleeding. This child's hematochezia was caused by HSP, but hemophilia could not be ignored during the treatment. Our case report adds to the present body of knowledge about the treatment of HSP associated hematochezia in a child with hemophilia A.

Long-Term Outcome of Children with Short Bowel Syndrome Treated with a Modification of the STEP Technique Avoiding Mesenteric Defect

BACKGROUND

 The Serial Transverse Enteroplasty Procedure (STEP) Registry has reported a 47% success to achieve enteral autonomy in pediatric short bowel syndrome (SBS). We have performed the STEP with a technical modification (MSTEP) consisting in stapler application without mesenteric defects that can also be applied to the duodenum. Our experience with this technique is described.

MATERIALS AND METHODS

 In this study, 16 children with SBS underwent MSTEP (2005-2019). Indications were nutritional autonomy achievement (n = 11, with duodenal lengthening in 5/11) and bacterial overgrowth treatment (n = 5).

RESULTS

 With a median follow-up of 5.8 years (0.7-13.7 years), 5 of 11 (45%) patients achieved enteral autonomy, 4 of them with duodenal lengthening. Four of four who preserved > 50% colon, while only one of seven with < 50% of colon achieved enteral autonomy (p < 0.05). After redo procedures, three of four attained enteral autonomy. Thus, 8 of 11 (73%) progressed to enteral autonomy, including all with duodenal lengthening. One child, already parenteral nutrition free, died due to central line sepsis. All the patients from the bacterial translocation group improved their metabolic/nutritional status, but one required subsequent enterectomy of the lengthened intestine due to multiple ulcers in the staple lines.

CONCLUSION

 The effectiveness of MSTEP to achieve enteral autonomy seems similar to the classical STEP. It can be applied to the duodenum. The retained colon length may influence the post-STEP enteral autonomy achievement.

Intestinal Failure: A Description of the Problem and Recent Therapeutic Advances

Pediatric intestinal failure occurs when gut function is insufficient to meet the nutrient and hydration needs of the growing child. The commonest cause is short bowel syndrome with maldigestion and malabsorption following massive bowel loss. The remnant bowel adapts during the process of intestinal rehabilitation. Management promotes the achievement of enteral autonomy while mitigating the risk of comorbid disease. The future of care is likely to see expansion of pharmacologic methods for augmenting bowel adaptation, tissue engineering techniques enabling immune suppression-free autologous bowel transplant, and the development of electronic health record tools for efficient, collaborative study and care improvement.

Restoring gut physiology in short bowel patients: from bench to clinical application of autologous intestinal reconstructive procedures

Introduction: Short bowel syndrome represents the leading etiology that causes intestinal failure both in children and adults. Total parenteral nutrition support has dramatically improved the prognosis for these patients but, if related irreversible complications occur, the alternative is represented by surgery and/or transplantation. Areas covered: Autologous gastrointestinal reconstructive procedures are a feasible, alternative approach with good long-term outcome data inexperienced surgical centers. Expert opinion: Ongoing innovative efforts have driven the surgical options for successful autologous reconstructive surgery: bowel elongation/tapering techniques (LILT, STEP, and the new SILT) together with the 'reversed bowel segment' procedure are now recognized procedures and all must be tailored to the individual patient needs to obtain the optimal result in terms of enteral autonomy. Background laboratory experimentation with new procedures e.g. options for bowel dilation techniques and distraction-induced enterogenesis, may provide additional management and treatment modalities.

Non-transplant Surgical Management of Short Bowel Syndrome in Children: An Overview

Management of severe Short Bowel Syndrome (SBS) is still one of the largest challenges of the medicine. Vast majority of the short bowel patients are children, the conditions that lead to this possible outcome most often are necrotizing enterocolitis (NEC), small intestinal volvulus as a result of intestinal malrotation, gastroschisis and the "apple peel" syndrome. Therefore, paediatricians and paediatric surgeons face this challenge most often. The nontransplant treatment appears to be effective using surgical procedure to increase absorptive surface and to reduce the transit time, but in some cases these procedures are enough to weaning of TPN. The aim of this review was to summarize the modern non-stransplant surgical management of short bowel syndrome.

Autologous intestinal reconstruction surgery

The management of short bowel syndrome has mainly been focused on intestinal rehabilitation as part of multidisciplinary team approach in specialized centers. While some patients go through a process of bowel adaptation that allows them to reach enteral autonomy, others reach a plateau before this and require prolonged parenteral nutrition and/or intestinal transplantation. Various autologous intestinal reconstruction procedures centered on bowel tapering have been described to increase functional intestinal area and help gain enteral autonomy. This review discusses the surgical techniques, advantages, limitations, and general outcomes of each procedure.

Long-term outcomes of pediatric intestinal failure

Management of pediatric intestinal failure has evolved in recent decades, with improved survival since the advent of specialized multidisciplinary intestinal failure centers. Though sepsis and intestinal failure associated liver disease still contribute to mortality, we now have growing data on the long-term outcomes for this population. While intestinal adaptation and parenteral nutrition weaning is most rapid during the first year on parenteral support, achievement of enteral autonomy is possible even after many years as energy and protein requirements decline dramatically with age. Intestinal transplant is an option for patients experiencing complications of long-term parenteral nutrition who are expected to have permanent intestinal failure, but outcomes are hindered by immunosuppression-related complications. Much of the available data comes from single center retrospective reports, with variable inclusion criteria, intestinal failure definitions, and follow-up durations; this limits the ability to analyze outcomes and identify best practices. As most children now survive long-term, the focus of management has shifted to the avoidance and management of comorbidities, support of normal growth and development, and optimization of quality of life for these medically and surgically complex patients.

Redefining short bowel syndrome in the 21st century

In 1968, Wilmore and Dudrick reported an infant sustained by parenteral nutrition (PN) providing a potential for survival for children with significant intestinal resections. Increasing usage of TPN over time led to some patients developing Intestinal Failure Associated Liver Disease (IFALD), a leading cause of death and indication for liver/intestinal transplant. Over time, multidisciplinary teams called Intestinal Rehabilitation Programs (IRPs) began providing meticulous and innovative management. Usage of alternative lipid emulsions and lipid minimization strategies have resulted in the decline of IFALD and an increase in long-term and transplant-free survival, even in the setting of ultrashort bowel (< 20 cm). Autologous bowel reconstructive surgeries, such as the serial tapering enteroplasty procedure, have increased the likelihood of achieving enteral autonomy. Since 2007, the number of pediatric intestinal transplants performed has sharply declined and likely attributed to the newer innovations healthcare. Recent data support the need for changes in the listing criteria for intestinal transplantation given the overall improvement in outcomes. Over the last 50 y, the diagnosis of short bowel syndrome has changed from a death sentence to one of hope with a vast improvement of quality of life and survival.

Success of serial transverse enteroplasty in an adult with extreme short bowel syndrome: a case report

Since its introduction as an alternative intestinal lengthening technique, serial transverse enteroplasty has been increasingly used as the surgical treatment of choice for children with refractory short bowel syndrome, but there have been few reports about the adult patients. This report describes the case of a 71-year-old man with a short bowel after distal gastrectomy with Billroth II reconstruction for gastric cancer, followed by extensive intestinal resection. The serial transverse enteroplasty operation was performed and lengthened the small intestine from 49 to 67 cm. The patient tolerated the procedure well and weaned off total parenteral nutrition. Liver function also improved. This case shows that the serial transverse enteroplasty procedure increases intestinal length. This procedure should be considered a surgical option for adult patients with extreme short bowel syndrome.

Intestinal Failure in Children

Children with intestinal failure have had improved survival, particularly those with extreme short bowel syndrome, over the last 10-15 y. This has been attributed to better understanding of the pathophysiology of intestinal failure, improvement in line care, recognition of the importance of a team approach as well as the progress of intestinal transplant as a viable option. Parenteral nutrition remains the cornerstone for the continual survival of these patients. This review will cover contemporary approaches to intestinal failure including post surgical approaches, non-transplant surgery, dietetic and medication approaches during the adaptation process, considerations for home parenteral nutrition and latest in intestinal transplantation.

Surgical management and autologous intestinal reconstruction in short bowel syndrome

Short bowel syndrome (SBS) is a serious condition with considerable morbidity and mortality. When treatment with parenteral nutrition fails and life-threatening complications occur, autologous intestinal reconstruction (AIR) should be considered before intestinal transplantation (ITx). Single or combined ITx should be reserved for patients with severe liver disease and as last resort in the treatment of SBS. Longitudinal intestinal lengthening and tailoring (LILT) has proven its value in AIR, but its availability depends on the expertise of the surgeons. Serial transverse enteroplasty (STEP) has similar success rates as LILT and fewer patients progress to ITx. STEP is also applicable at small bowel dilatation in ultra-short bowel syndrome. The scope may be widened when duodenal dilatation can be treated as well. Spiral intestinal lengthening and tailoring (SILT) is a promising alternative. More research is needed to confirm these findings. Therefore we suggest an international data registry for all intestinal lengthening procedures.

Intestinal Anastomotic Ulcers in Children With Short Bowel Syndrome and Anemia Detected by Capsule Endoscopy

OBJECTIVES

Anastomotic ulcers are a known cause of anemia in children with a history of intestinal resection. Upper endoscopy and colonoscopy can be used to diagnose these ulcers; however, the area of involvement may be difficult to visualize with standard endoscopic techniques. Capsule endoscopy (CE) offers an alternative method for visualizing the small bowel in these patients. We describe a cohort of patients with short bowel syndrome (SBS) and anemia who had anastomotic ulcers detected by CE.

METHODS

Retrospective chart review of patients with SBS at our institution who underwent CE for chronic gastrointestinal (GI) blood loss.

RESULTS

Four patients who underwent a total of 6 CE procedures were identified. The underlying diagnoses included necrotizing enterocolitis (n = 2), gastroschisis (n = 1), and jejunal atresia (n = 1). All of the patients had their ileocecal valves resected during previous surgeries and had received blood transfusions within the previous several months. The median age at the time of CE was 5.5 years (range 4-14 years). Enterocolonic anastomotic ulcers were noted in the studies as wide, flat circumferential lesions with a white base. The CE results guided a change in medical management in all of the 4 patients, including surgical revision of their anastomosis.

CONCLUSIONS

CE may be a helpful adjunctive tool for detecting anastomotic ulcers in patients with SBS and chronic GI blood loss.
