A new anastomosis technique for intestinal diseases with proximal dilated segments

Antimesenteric sleeve tapering enteroplasty with end-to-end anastomosis versus primary end-to-side anastomosis for the management of jejunal/ileal atresia

BACKGROUND/OBJECTIVE

Small bowel atresia commonly causes neonatal intestinal obstructions. Technical problems are associated with the surgical management of atresia using primary end-to-end anastomosis. Furthermore, the significantly dilated proximal loop may be associated with the stasis of intestinal fluid, thus increasing pressure on the anastomosis and prolonging fasting time before initiation of oral intake. This study aimed to perform antimesenteric tapering of the proximal loop using a linear stapler to reduce its diameter and facilitate anastomosis with the distal loop.

METHODS

This retrospective study included 57 neonates diagnosed with jejunoileal atresia. They were categorised into two groups: Group A (n = 29), which included neonates treated using antimesenteric sleeve enteroplasty tapering using a linear stapler and Group B (n = 28), which included neonates treated at the primary end of the proximal loop to the side of the distal loop anastomosis.

RESULTS

The mean operative time was 122.5 min in group A vs. 118 min in group B, and the mean duration to reach full oral intake was 17 days in group A vs. 20.2 days in group B (p = 0.03). The mean length of hospital stay was 25 and 35 days in groups A and B, respectively (p = 0.042).

CONCLUSION

Tapering the proximal dilated bowel loop to achieve anastomosis with the distal loop improved the transient time, reduced stasis and its associated translocation and colonisation, and allowed for early initiation and maintenance of oral intake. All these parameters shortened the overall length of hospital stay.

T-tube enterostomy in the management of apple-peel atresia: A case series from a single center

BACKGROUND AND OBJECTIVE

Although complex atresias, such as apple-peel and multiple atresias, comprise a smaller percentage, they are usually associated with a higher incidence of postoperative complications and mortality rate. Contrary to simple atresias where the surgical technique of choice usually entails bowel resection and anastomosis with or without enteroplasty, managing apple-peel atresia remains more sophisticated. Decompressive and functionalizing stomas are sometimes mandatory to overcome problems such as increased wall thickness and the wide disparity among the anastomotic ends. Few reports discussed using tube enterostomy in the management of apple-peel atresia; nonetheless, no previous prospective studies were conducted to discuss its efficacy on a larger population. In this study, we are describing our experience using this technique on 12 patients suffering from apple-peel atresia in our center.

METHODS

A prospective study was conducted from June 2015 to May 2020, where all children who were found to have apple-peel atresia were included in the study. T-tube was placed through an enterotomy through the dilated proximal bowel, around 10 cm before the anastomotic line, and was kept in place using a double suture (Stamm technique) before closing the anterior face of the anastomosis. The short distal limb of the T-tube was oriented toward the anastomotic line, while the long proximal limb was directed proximally. After finishing the anastomosis, the T-tube was delivered outside the abdominal wall, anchoring the enterostomy along with the proximal dilated jejunum against the anterior abdominal wall.

RESULTS

A total of 12 cases were encountered throughout the period of study. The mean age at operation was 4 days and the mean birth weight was 2700 g. The mean time for starting oral feeding postoperatively and T-tube removal was 8 and 10.5 days, respectively. Cases were discharged after a mean of 22 days. As regards morbidity and mortality, a single case developed skin excoriations at the site of tube insertion and was managed conservatively using topical ointments and another case died from overwhelming sepsis 3 days after the operation.

CONCLUSION

T-tube enteroplasty is a safe and feasible option in the surgical management of apple-peel atresia. The main strength of our study is its prospective nature and that it includes apple-peel atresia cases only. However, the main limitation is that a larger sample is needed.
