A novel intraoperative Esophagus-Sparing Anastomotic Narrowing Revision (ESANR) technique for patients who underwent esophagojejunostomy: three case reports and a review of the literature.

AIM

The aim of this study was to introduce the Esophagus-Sparing Anastomotic Narrowing Revision (ESANR) technique for the intraoperative management of anastomotic narrowing and to conduct a literature review to provide an algorithm for the management of narrowing and strictures that may develop secondary to esophagojejunostomy.

METHODS

Three patients with anastomotic narrowing during esophagojejunostomy were analyzed between September 2019 and June 2024. The anastomotic narrowing was detected by intraoperative gastroscopy after reconstruction. The ESANR technique was performed for the management of anastomotic narrowing. We conducted a systematic search of PubMed, Embase, and Web of Science databases for studies published up to June 2024 related to the treatment of anastomotic stricture. Data on the number of patients, sex, age, type of anastomosis, treatment, and outcomes were collected.

RESULTS

The ESANR technique proved effective for the management of anastomotic narrowing in patients who underwent esophagojejunostomy during gastric cancer surgery. No anastomotic stricture or leakage was found following ESANR, and all three patients recovered without complications. 12 studies with a total of 174 patients were analyzed. The management of anastomotic stricture, which included Balloon Dilation (BD), Endoscopic Incision Therapy (EIT), stent placement, Endoscopic combination therapy (Needle-Knife stricturotomy NKS, Balloon Dilation with Triamcinolone Injection TAC), and re-do laparoscopic esophagojejunostomy.

CONCLUSIONS

In conclusion, the ESANR technique demonstrates potential advantages in addressing anastomotic narrowing in esophagojejunostomy. However, further clinical data and analyses are necessary to verify its effectiveness and establish robust statistical support.
