Level 3	Incomplete peritoneal closure or its breakdown in endoscopic preperitoneal hernia repair increases the risk of bowel obstruction.
Level 3	TAPP procedure presents a higher statistical risk of small-bowel obstruction than TEP.
Level 5	The most appropriate peritoneal closure is achieved by running absorbable suture.
Level 5	Running suture seems to cause less pain compared with clip/tack closure.
Level 5	The closure of entrance of indirect sacs may reduce the risk of internal hernia with consecutive incarceration, strangulation, or small-bowel obstruction.
