Open right hemicolectomy is performed to treat malignant tumors, polyps, and other conditions in the ileocecal region, ascending colon, and hepatic flexure. The procedure involves mobilizing the right colon, ligating blood vessels, resecting the involved bowel segments, and creating an ileocolic or ileotransverse anastomosis. Key steps include careful dissection to avoid injury to nearby structures like the duodenum and ureter, and ensuring a well-vascularized, tension-free anastomosis to minimize risks of leakage. Post-operative care focuses on early ambulation and advancing diet based on progress.

6. • Mobilisation of hepatic flexure
Divide the hepatico-colic ligament
• Mobilisation of greater omentum with
Transverse Colon
For simple Rt hemicolectomy Divide
omentum close to Transverse colon
For Radical hemicolectomy Divide omentum
just below the gastro-epiploic arcade

7. • Ligation of the blood vessels
Come to right side of table
Lift the terminal ileum and right colon
Transilluminate the mesentery
• Ligation of blood vessels
Clamp, divide and ligate the ileo-colic and right
colic vessels at their origin from the superior
mesenteric artery
Clamp, divide, and ligate the right branch of the
middle colic artery.

8. • Transaction of Ileum
Clear the bowel wall at the sites of
transection and apply crushing clamps.
Apply occlusion clamps on the proximal
small bowel and distal large bowel.
• Transaction of Transverse Colon
Divide the bowel on the crushing clamps leaving
them on the specimen
You can also transact them using GIA stapler

9. • Anastomosis of Ileum to Transverse
Colon- Hand-sewn Anastomosis
End-to-end anastomosis: anastomosis
either using a single layer of interrupted
sero-muscular 3/0 Vicryl or PDS sutures or
alternatively as a two-layer suturing
technique.

12. Post-op Care
No need to continue antibiotics postoperatively unless there is intraabdominal
infection.
Nasogastric tube is not routinely placed.
Begin ambulating on postoperative day 1.
Foley catheter can usually be removed on postoperative day 1 or 2 unless an
epidural remains in place.
The patient can be started on a liquid diet. The diet can be advanced based on
clinical progress.
DVT prophylaxis should be continued until the time of discharge and can be
considered as an outpatient in certain subsets of patients.
Patient should be counseled about the initial changes in bowel habits including
more frequent, loose stools and the possible appearance of blood clots in the first
few bowel movements.

13. Pearls & Pitfalls
Colon mobilization:The plane between the mesocolon and the retroperitoneum is an avascular embryologic
plane that should be dissected sharply. Excess blood loss during this dissection alerts the surgeon that the
incorrect plane was entered.
Vascular dissection: -During dissection of the middle colic vessels, avulsion of the large collateral branch
that connects the inferior pancreaticoduodenal vein with the middle colic vein and superior mesenteric vein
can result in bleeding that is difficult to control because the vein retracts and cannot be isolated easily.
- Avoiding excess upward and medial traction of the right colon while mobilizing the hepatic flexure best
prevents this.
- Transillumination of the mesocolon and the mesentery of the terminal ileum can
help to identify vascular arcades to minimize iatrogenic injury in patients with thick
mesentery and can assure good blood supply to the anastomosis
Anastomosis: A well-vascularized, tension-free anastomosis minimizes the risk of anastomotic breakdown
- If there is any doubt regarding the integrity of the anastomosis, the bowel segments should be further
resected to healthy, vascularized bowel.
- Blood supply to the anastomosis can also be further assessed with Doppler ultrasound if necessary.
