Objective To investigate the therapeutic efficacy and choice of opportune time for appendectomy during prolonged deployment at sea.Methods Retrospective analysis was made on the 44 cases of appendectomy performed by the medical teams of No.413 hospital,from April 2000 to August 2015,during prolonged deployment at sea.The patients were divided into 2 groups.The patients in the early surgical group received surgery within 48 hours of onset,and those in the delayed surgical group had surgery 48 hours after onset.Surgery-related medical data,recovery after surgery and the incidence of complications were closely observed and analyzed.Results There were significant differences in intra-surgical hemorrhage,days of absence from combat posts due to diseases and incidence of complications between the 2 groups [(21.5 ± 5.7) mlvs.(28.1±7.8) ml,(6.5±1.2) dvs.(9.2±3.4) d,0 vs.15％,t=3.15,t=3.38,x2=3.86] (P ＜ 0.05).However,no significant differences could be seen in surgical time and recovery of exsufflationtime [(31.9±5.3) minvs.(34.1±9.8) min,(17.5 ±3.2) h vs.(19.5 ±3.4) h,t=0.90,t =2.00] (P ＜ 0.05).Conclusions The therapeutic efficacy of appendectomy during prolonged deployment at sea was on the whole satisfactory.If symptoms of patients were not improved following conservative treatment,appendectomy should be performed within 48 hours after onset.
