Mechanical Reinforced Terminolateral Ileo-Transverse Anastomosis: An Option After Right Hemicolectomy-A 452 Patients...

Bowel reconstruction techniques after right hemicolectomy has currently been objective of review, due to the high rate of anastomotic leak. The aim of this study is to analyse our results of the mechanical reinforced terminolateral ileo-transverse anastomosis.

A prospective and descriptive study of a consecutive series of right colonic cancer cases that underwent right hemicolectomy. Mechanical reinforced terminolateral ileo-transverse anastomosis technique was carried out in all patients. Demographics, emergency or elective surgery, surgical management, postoperative complications, rate of anastomotic leak, need for surgical procedure after complication, average stay, and mortality were analysed.

A total of 452 patients underwent surgery between 2010 and 2017. Of those, 40.6% were female and 59.4% were male. The average age and body mass index (BMI) was 72±11.3 years old, and 26±7.1, respectively. Elective surgery was carried out in 405 (89.6%) patients. Laparoscopic approach was used in 250 patients (61.7%) and 6% needed conversion. Only 41 patients (10.6%) had major complications (Clavien-Dindo III-IV). The rate of postoperative paralytic ileus reach was up to 13.9%. Reintervention was needed in five patients (1.1%) due to anastomotic leak and three (0.7%) of them from the elective surgery subgroup. There were 10 patients (2.2%) with postoperative gastrointestinal bleeding. The average stay was 8.2±2.8 days and late postoperative mortality in the first 30 days was 2%.

Mechanical reinforced terminolateral ileo-colic anastomosis is a safe technique with a low anastomotic leak rate. Although our results using this approach seem promising, postoperative paralytic ileus is still a high-rate complication.
