Purpose: The optimal time to perform elective surgery remains to be determined. We analyzed the impact of time interval to surgery on short-terme outcome parameters in patients undergoing elective laparoscopic left colonic resection for diverticulitis.

Materials And Methods: Retrospective analysis of two series of case-matched patients according to the timing of operation after the last episode of diverticulitis: group A (within 90 days) and group B (beyond 90 days).

Results: 332 patients had left colonic resection for diverticulitis. 117 patients were included in group A vs 114 patients in group B. Overall abdominal morbidity in Group A was 21% vs 5% in group B (p = 0.02). Mean hospital stay was 7.7 days in group A vs 5 days in group B (p = 0.08). Residual inflammation was significantly increased in group A (31%) as compared to group B (11%) (p = 0.01).

Conclusions: Laparoscopic left colonic resection for acute diverticulitis is best performed beyond the third month after the last acute episode.

Objective: Laparoscopic nephron sparing surgery (NSS) can be performed by mainly 2 methods, offclamp or on-clamp. Continuous bleeding during the off-clamp method may impair the clear visualization of the border between the tumor and parenchyma, even though it is done safely in experienced hands. Therefore, some surgical modifications may be needed during mass excision and renorraphy.

Background And Aims: Probe-based confocal endomicroscopy (pCLE) allows real-time microscopic visualization of the intestinal mucosa surface layers. Despite remission achieved through anti-tumor necrosis factor or vedolizumab therapy, anomalies in the intestinal epithelial barrier are observed in inflammatory bowel disease (IBD) patients. Our study aimed to assess these abnormalities in non-IBD individuals and compare them with IBD patients in endoscopic remission to identify the associated factors.
