 In the literature, there is no consensus about the role of the laparoscopic peritoneal lavage in the management of complicated acute diverticulitis. Recently, three important prospective randomized-control studies SCANDIV, LOLA, DILALA have reported contradicting conclusions, as two of them SCANDIV and LOLA state that LPL is not superior to sigmoidectomy for the high reoperation rate and morbidity, while DILALA confirms that LPL is feasible and safe in the short-term. To our knowledge, no international guidelines promote the use of LPL in complicated acute diverticulitis. We believe this technique could be safely used in a selected cohort of patients and, in some circumstances, could represent a bridge to a possible planned resection. The aim of the study is to collect and analyze the multicentric data of the LPL and LS and give a substantial contribution to the scientific community about this very debated topic.
