Intestinal plication: an alternative to tapered jejunostomy in functional small bowel obstruction

Modified Antimesenteric Tapering Enteroplasty: An Alternative Technique for the Treatment of Dysfunctional Anastomosis in Patients With Short Bowel

INTRODUCTION

Several techniques have been described to taper the dilated small bowel to improve intestinal motility and decrease complications related to overdilated small bowel, including longitudinal intestinal lengthening and tapering, serial transverse enteroplasty, and spiral intestinal lengthening and tailoring. We propose an alternative technique designed to optimize bowel function and minimize the effects of recurrent small-bowel bacterial overgrowth in patients with short or ultra-short gut syndrome and dysfunctional anastomosis with maintenance of the actual absorptive surface.

TECHNIQUE

The dilated side-to-side anastomosis is identified, and the mesentery leaves from both the proximal and distal small-bowel loops are separated by using blunt dissection. The previous anastomosis is divided longitudinally with a GI stapler. Once the small-bowel transection is completed, 2 separate blind loops of intestine are created, each one with half the circumference of the dilated side-to-side anastomosis. The antimesenteric stapled line is then reinforced with an outer layer of running suture. The blind loops of the tapered small bowel are then trimmed and anastomosed in an end-to-end isoperistaltic fashion in 2 layers.

RESULTS

There were no postoperative complications. The length of the tapering ranged from 10 to 23 cm, corresponding to approximately 16% (range, 13%-20%) of the remaining small-bowel length. Three of 4 patients presented significant improvement of their symptoms and were able to have their parenteral support discontinued.

CONCLUSIONS

Modified antimesenteric tapering enteroplasty is an alternative technique to improve intestinal motility and treat patients with short-bowel syndrome and dysfunctional side-to-side anastomosis without the need for further small-bowel resection. This bowel-sparing technique represents a valuable option in the armamentarium of the surgeon who manages patients with intestinal failure.

E, Lago DVD, Ramaciotti O. Análise quantitativa das ondas fisiológicas do intestino delgado após plicatura parcial e ordenada do íleo em ratos

O presente estudo experimental analisou os movimentos intestinais espontâneos do jejuno proximal e íleo distal, em ratos, após plicatura ordenada no íleo. Foram utilizados 31 ratos albinos distribuídos em três grupos submetidos ao mesmo experimento: grupo A - animais reoperados no 10º pós-operatório da plicatura ileal ordenada; grupo B - animais reoperados no 20º pós-operatório; grupo C - animais reoperados no 60º pós-operatório. Realizou-se plicatura ordenada do íleo, em quatro segmentos intestinais com 2cm de extensão cada. Na reoperação procedeu-se à secção, em peça única, dos segmentos intestinais plicados, do segmento jejunal pré-plicatura e do segmento ileal pós-plicatura. Utilizou-se dois quimógrafos para registro simultâneo das ondas intestinais espontâneas. Foram analisadas as freqüências das ondas fisiológicas do tipo I, II e III nos segmentos do jejuno proximal e do íleo distal nos grupos A, B e C, separadamente e em conjunto. O estudo estatístico foi realizado pelos métodos não paramétricos de Kruskal-Wallis, Friedman e Wilcoxon. Os resultados do presente experimento permitiram concluir que a plicatura ileal parcial ordenada não interferiu de maneira definitiva nos movimentos intestinais espontâneos representados pelas ondas tipos I, II e III no segmento jejunal pré plicatura e no segmento ileal pós plicatura após dois meses do procedimento.
