ARTICLE HIGHLIGHTS
Research background

Right sided diverticulitis is very frequent in Asian countries, while in western countries it has always been considered very rare. On the other hand, in recent studies, the condition has been shown to be increasing in recent years.

Research motivation

Despite this rapid spread, there are no clear guidelines on the management of RSD. Until now, their management has been based on knowledge gained from left sided diverticulitis.

Research objectives

The authors therefore wanted to analyze the studies in the literature to have a broader and deeper point of view to understand what could be the correct management.

Research methods

The authors analyzed the articles from western countries starting from 1990 in which the management and the subsequent outcome of right sided diverticulitis were shown.

Research results

The authors found that most cases of right colonic diverticulitis are treated effectively with non-operative management, reserving surgical treatment especially for complicated cases. Recurrences have a low rate and are also successfully treated conservatively.

Research conclusions

Right sided diverticulitis has a similar management in both western and Asian countries.

Research perspectives

Further studies will serve to identify more precisely which cases should be reserved for surgical treatment.
