Experiences with intestinal failure from an intestinal rehabilitation unit in a country without home parenteral nutrition

Comparison of the effect of Everolimus, Prednisolone, and a combination of both on experimentally induced peritoneal adhesions in rats

Postoperative intra-abdominal adhesions represent a significant post-surgical problem. Its complications can cause a considerable clinical and cost burden. Herein, our study aimed to investigate the effect of Everolimus on peritoneal adhesion formation after inducing adhesions in rats. In this experimental study, adhesion bands were induced by intraperitoneal injection of 3 ml of 10% sterile talc solution in 64 male albino rats. The first group served as the control group. The second one received oral Prednisolone (1 mg/kg/day), the third received Everolimus (0.1 mg/kg/day), and group four received both drugs with similar dosages for four consecutive weeks. The formation of adhesion bands was qualitatively graded according to the Nair classification. The rats in the control group had extensive adhesions between the abdominal wall and the organs. Regarding substantial adhesion formation, 50% (8/16) of animals in the control group had substantial adhesions, while this rate in the groups receiving Prednisolone, Everolimus, and combination treatment was 31%, 31%, and 31%, respectively. Also, 68.75% (5/11) of the Prednisolone recipients had insubstantial adhesions, the same as Everolimus recipients, while in the combination group, 66.66% (10/15) rats had insubstantial adhesions. Everolimus demonstrated satisfactory results in reducing the rates of induced peritoneal adhesion in an experimental model, similar to Prednisolone and superior to a combination regime.

Hospital Cost of Inflammatory Bowel Disease and Its Determinants in a Multicenter Study From Iran

Background: In the current era of monitoring healthcare costs for patients with inflammatory bowel disease (IBD), there has been a shift in the pattern of such costs. In this cross-sectional study conducted in three hospitals in Iran from 2015 to 2021, we aimed to assess the in-hospital costs of IBD and identify predictors of higher total hospital costs in hospitalized patients with IBD. Methods: This cross-sectional study was conducted at three hospitals in Iran. For the purpose of this study, we collected demographic and clinical information, as well as cost data for patients with IBD. Two non-parametric statistical procedures, classification and regression trees (CARTs) and quantile regression forests (QRFs), were employed to identify the main factors related to hospital costs of IBD, which served as the dependent variable in our analysis. Results: During 7 years, 930 admissions occurred in these three hospitals. 22.3% of patients (138 of 619) were readmitted, and 306 (49.4%) were male. The mean age of the patients was 33 (SD=18.9) years. A total of 454 patients (73.3%) had ulcerative colitis (UC), and 165 patients (26.7%) had Crohn's disease (CD). Hotelling and medication costs accounted for the largest share of the total hospital costs, with percentages of 30.61% and 23.40%, respectively. Length of stay (LOS) was found to be the most important variable related to hospital costs of IBD in both QRF and CART models, followed by age and year of hospital admission in QRF. Additionally, in the CART model, hospital type and year of hospital admission were also significant predictors of hospital costs for patients with IBD. Conclusion: The present study showed that LOS, age, year of admission, and the hospital where the patient is admitted are all important factors that determine hospital costs for patients with IBD. Patients admitted for 20.5 days or longer had the highest hospital costs. These findings can be used as thresholds for future DRG policies.

Growing experience of surgical gut rehabilitation: essential role in the management of gut failure in adult patients

PURPOSE OF REVIEW

With the inherent therapeutic limitations of gut transplantation, the concept of surgical gut rehabilitation was introduced to restore nutritional autonomy in pediatric patients. With favorable outcomes in these young patients, there has been increasing interest in the applicability of gut rehabilitative surgery to a growing population of adults with gut failure due to various etiologies. We aim to review the current status of surgical gut rehabilitation for adult gut failure patients in the era of multidisciplinary gut rehabilitation and transplantation.

RECENT FINDINGS

Indications for surgical gut rehabilitation have been gradually expanding, with gut failure after bariatric surgery recently added. Serial transverse enteroplasty (STEP) has been used with favorable outcomes in adult patients, including those with intrinsic intestinal disease. Autologous gut reconstruction (AGR) is the most frequently used surgical rehabilitative method; its outcome is further improved with conjunctive use of bowel lengthening and enterocyte growth factor as a part of comprehensive gut rehabilitation.

SUMMARY

Accumulated experiences have validated the efficacy of gut rehabilitation for survival, nutritional autonomy, and quality of life in adults with gut failure of various etiology. Further progress is expected with growing experience around the world.

[Fistuloclysis - A useful tool in patients with intestinal failure]

Introduction

Introduction: fistuloclysis is a technique described by Teubner et al. whereby a fistula is used as a route of nutritional administration. This procedure is an alternative to the management of patients with intestinal failure receiving parenteral nutritional support. Case reports: we present two clinical cases of patients with different medical histories but who coincided in malnutrition, abdominal sepsis with fistulas, and their awaiting intestinal reconnection. In both cases nutritional support was administered with parenteral nutrition and enteral nutrition through fistuloclysis. Discussion: enteral nutrition through fistuloclysis improves function of the intestinal barrier, reduces the rate of intrahospital infection in critically ill patients, improves immune function, prevents atrophy of the intestinal mucosa, and that is why as soon as an enteral access is located we must take advantage of this route so that our patients may experience the benefits of fistuloclysis regardless of caloric intake.

Update on surgical management of enteroatmospheric fistulae in intestinal failure patients

PURPOSE OF REVIEW

The surgical management of enteroatmospheric fistula (EAF) in patients with intestinal failure represents a major challenge for a surgical team and requires proficiency in sepsis management, nutritional support and prehabilitation, beside expertise in visceral and abdominal wall surgery. This review provides an update on the current recommendations and evidence.

RECENT FINDINGS

Reconstructive surgery should be performed at a minimum of 6-12 months after last laparotomy. Isolation techniques and new occlusion devices may accelerate spontaneous EAF closure in selected cases. Chyme reinfusion supports enteral and parenteral nutrition. Stapler anastomosis and failure to close the fascia increase the risk of EAF recurrence. Posterior component separation, intraoperative fascial tension and biological meshes may be used to accommodate fascial closure.

SUMMARY

Timing of reconstructive surgery and previous optimal conservative treatment is vital for favorable outcomes. Wound conditions, nutritional support and general patient status should be optimal before attempting a definitive fistula takedown. Single stage procedures with autologous gut reconstruction and abdominal wall reconstruction can be complex but well tolerated.

Serial transverse enteroplasty and nipple valve construction, two life saving techniques for patients with short bowel syndrome, a report of 5 cases

Background

Various abdominal pathologies end up with surgical resection of small intestine. When the small intestine remnant is too short for adequate fluid and micronutrients absorption, short bowel syndrome is diagnosed. The disabling condition needs a multidisciplinary approach to design parenteral nutrition, care for thrombotic, hepatic and infectious complications and gradually wean the patient from parenteral nutrition. Various surgical techniques have been introduced to increase absorptive mucosa and enhance the intestinal adaptation process. Serial transverse enteroplasty and nipple valve reconstruction are among the procedures, which will be discussed in the current article.

Case presentation

Herein, we presented 5 cases of short bowel syndrome as a consequence of abdominal laparotomies, patients were referred to our center to receive parenteral nutrition and to be prepared for the final autologous gastrointestinal reconstruction or intestinal transplantation, if indicated.

Conclusion

Patient’s age, performance status and bowel remnant length determines the appropriate technique for autologous gastrointestinal reconstruction. Serial transverse enteroplasty is designed to increase bowel’s length by creating zigzag patterns through dilated bowel loops. Presence of ileocecal valve is crucial to delay intestinal transit time and to prevent colonic bacterial transfer to ileum. Patient’s with ileocecal valve loss benefit from creating an artificial valve, namely, nipple valve.
