This study suggests that SILC for colorectal cancer is a safe and feasible option with better cosmetic results and less pain in strictly selected patients. SILC can also produce good oncological results with similar postoperative outcomes to MILC.

NOSE with prolapsing technique was applied in 14 SILC procedures for colorectal cancer patients. All procedures were successful, and there were no anastomotic leakages in the series. This technique enabled us to perform pure SILC safely without affecting cosmesis, even in cases where we needed to cut the lower rectum.

In TAPP for patients following prostatectomy, surgery can be performed safely and reliably without prolonging the operative duration by selecting a skilled practitioner and standardizing the technique.

CaseWe report a rare case of omental herniation through the esophageal hiatus. A 46‐year‐old man visited our emergency department complaining of epigastralgia. Abdominal examination revealed muscular defense and rebound tenderness in his upper abdomen. A computed tomography scan showed a fat density mass in the posterior mediastinum. A laparoscopic operation was carried out under the diagnosis of omental herniation through the esophageal hiatus.OutcomeAbdominal pain disappeared dramatically after the operation. The postoperative course was uneventful.ConclusionAlthough a fat density mass in the posterior mediastinum is likely to be diagnosed as a lipomatous tumor, omental herniation through the esophageal hiatus should be taken into consideration as a possible diagnosis for acute abdominal pain in the emergency department.
