It was reported via journal article title: randomized clinical trial of intracorporeal versus extracorporeal anastomosis in laparoscopic right colectomy (iea trial) authors: j.Bollo, v.Turrado, a.Rabal1, e.Carrillo, i.Gich, m.C.Martinez, p.Hernandez and e targarona.Citation: bjs 2020; 107: 364¿372.Doi: 10.1002/bjs.11389.The aim of this rct was to compare the two surgical techniques, and to define the possible benefits of ia versus ea in patients undergoing elective right colectomy.This randomized, single-blind and single-centre clinical trial, the intracorporeal versus extracorporeal anastomosis (iea) study involves 139 patients who were referred for treatment of a right colonic adenocarcinoma from may 2015 to june 2018.Sixty-nine patients (34 male and 35 female; mean age (sd): 72.7 (10.4) years; age range: 45-89 years; bmi: 27.4(5.4) kg/m2) were included in the intracorporeal anastomosis group, and 70 patients (39 male and 31 female; mean age (sd): 70.9(11.7) years; age range: 28-90 years; bmi: 26.3 (4.7) kg/m2) were included in the extracorporeal anastomosis group.During the procedure, the first trocar, endopath® xcel¿ with optiview¿ (ethicon, tampa, florida, usa), was inserted in the left iliac fossa to create the pneumoperitoneum, and an exploratory laparoscopy undertaken.A second trocar was placed at the right iliac fossa and another in the suprapubic region to act as working ports.A fourth trocar was positioned in the left subcostal flank for assistance.If intracorporeal anastomosis (ia) was designated, dissection of the mesocolon was completed, and the ileum and transverse colon were transected using an endo-gia stapler (echelon flex¿, 60 mm, blue cartridge; ethicon).A side-to-side antiperistaltic ileocolic anastomosis was created with the endo-gia stapler (echelon flex¿, 60 mm, blue cartridge; ethicon) and the enterotomy was closed with two running sutures of prolene® 2/0 (ethicon).If extracorporeal anastomosis (ea) was designated, a transverse incision was made.The ileum and colon were extracted, and dissection of the mesocolon completed.A side-to-side antiperistaltic anastomosis was created with a gia stapler (proximate®75 mm, blue cartridge; ethicon) and the two bowel ends were closed with a ta stapler (proximate® tx 90 mm; ethicon).Reported complications in intracorporeal anastomosis group included mean (sd) postoperative pain score of 2.73(2.32) at day 1 (n-?), mean (sd) postoperative pain score of 1.81(1.85) at day 2 (n-?), mean (sd) postoperative pain score of 2.06(2.19) at day 3 (n-?), mean (sd) postoperative pain score of 1.72(1.91) at day 4 (n-?), mean (sd) postoperative pain score of 1.71(2.18) at day 5 (n-?), mean (sd) decrease in haemoglobin level of 8.8 (1.7) (n-?) in which 5 patients had a red blood cell transfusion, grade i paralytic ileus (n-4), grade i wound seroma (n-3), grade ii paralytic ileus (n-5) and parenteral nutrition, anaemia (n-3) in which the patient had a rbc transfusion, grade ii lower gastrointestinal bleeding (n-2) with rbc transfusion, grade ii wound infection (n-3), grade ii anastomotic leak (n-3) in which 2 were treated with antibiotic treatment and 1 with surgical reoperation.In extracorporeal anastomosis group included mean (sd) postoperative pain score of 3.01(2.29) at day 1 (n-?), mean (sd) postoperative pain score of 2.91(2.25) at day 2 (n-?), mean (sd) postoperative pain score of 2.36(2.12) at day 3 (n-?), mean (sd) postoperative pain score of 2.49(2.23) at day 4 (n-?), mean (sd) postoperative pain score of 2.42(1.93) at day 5 (n-?), mean (sd) decrease in haemoglobin level of 17.1 (1.7) (n-?) in which 9 patients had a red blood cell transfusion, grade i paralytic ileus (n-10), grade i wound seroma (n-3), lower gastrointestinal bleeding (n-1) in which the patient had a reoperation, grade i lower gastrointestinal bleeding (n-6), grade ii paralytic ileus (n-11) and parenteral nutrition, anaemia (n-5) in which the patient had a rbc transfusion, grade ii lower gastrointestinal bleeding (n-3) in which the patient had a rbc transfusion, grade ii wound infection (n-3), garde ii colitis (n-1), grade ii anastomotic leak (n-5) in which 3 were treated with antibiotic treatment, 1 with radiological drainage and 1 with surgical reoperation, ileal ischaemia (n-1) in which the patient had a reoperation, and intra-abdominal haematoma (n-1) in which the patient had a reoperation.In conclusion, duration of hospital stay was similar, but ia was associated with less pain and fewer complications.
