Objective? To?explore?the?clinical?effect?of?laparoscopic?exploration?in?the?diagnosis?and?treatment?of?abdominal?open?trauma.? Methods? Patients?with?abdominal?open?trauma?admitted?to?the?First?Affiliated?Hospital?of?Dalian?Medical?University?from?August?to?December?in?2018?were?enrolled.?According?to?different?exploration?methods,?11?patients?undergoing?laparoscopic?exploration?were?grouped?into?laparoscopy?group?and?20?patients?undergoing?exploratory?laparotomy?were?grouped?into?laparotomy?group.?The?operation?time,?the?length?of?hospital?stay,?cases?without?abdominal?visceral?injury,?postoperative?exhaustion?time,?cases?with?complications?and?incision?length?were?compared?between?the?two?groups.? Results? All?the?31?patients?were?experienced?with?knife?stab?wound,?with?26?males?and??5?females,?and?the?age?was?(33.39±11.47)?years?old.?Compared?with?the?laparotomy?group,?the?length?of?hospital?stay?was?significantly?shorted?in?the?laparoscopy?group?(days:?6.64±2.94?vs.?11.65±5.62),?the?postoperative?exhaustion?time?was?significantly?decreased?(hours:?40.36±29.04?vs.?75.60±42.84),?the?cases?with?complication?was?significantly?decreased?(case:?1?vs.?9),?the?incision?length?was?significantly?shorted?(cm:?5.50±5.14?vs.?16.95±5.28),??all?of?which?results?had?statistical?significance?(all?P??0.05).?Confirmed?by?surgical?exploration,?5?patients?had?no?abdominal?visceral?injury,?with?3?in?the?laparoscopy?group?and?2?in?the?laparotomy?group,?and?the?result?had?no?significant?difference?between?the?two?groups?(P?>?0.05).? Conclusion? For?patients?with?abdominal?open?trauma,?laparoscopic?exploration?is?helpful?for?diagnosis?as?quickly?as?possible,?with?less?trauma?and?reduction?of?complications?incidence,?and?is?conducive?to?postoperative?rehabilitation.
