Abstract
Objective: Non-cirrhotic portal hypertension (NCPH) is the most common cause of portal hypertension and upper gastro-intestinal bleeding in children and adolescents in developing nations. It is characterized by features of portal hypertension with preserved liver function. Proximal splenorenal shunt (PSRS) and esophagogastric devascularization are the two most commonly performed surgeries for its management. The present study is aimed at comparison of surgical outcomes between these two procedures.
Material and Methods: Between April 2018 and March 2022, prospectively maintained data of consecutive NCPH cases who underwent surgical intervention was reviewed retrospectively. Cases were categorized into two groups- shunt surgery and devascularization. The pre-operative characteristics, peri-operative morbidity and long-term outcomes were compared between the groups.
Results: Of 112 cases who were treated during the study period, 54 cases which underwent surgery were included in the study. Of these, 20 cases underwent PSRS, and splenectomy and devascularization was performed in 34 cases. There was no difference in pre-operative variables between the two groups. Patients undergoing PSRS experienced longer duration of surgery (260 vs. 200 minutes, p< 0.001), and those in the devascularization group had significantly greater operative blood loss (350 vs. 455 ml, p< 0.001). Post-operative morbidity was comparable between the two groups. Hypersplenism was corrected in all cases and no cases reported rebleeding after median follow-up of 30 months. Three cases in each group developed features of portal biliopathy in follow up period.
Conclusion: Both PSRS and devascularization procedures have comparable efficacy and safety in the management of NCPH.
