Objective To compare the clinical efficiency between laparoscopic enterodialysis and open enterodialysis. Methods Clinical data of 25 cases of adhesive intestinal obstruction treated by laparoscopic enterodialysis (Laparoscopic Group) from December 1999 to December 2002 were retrospectively reviewed and compared with clinical records of 23 cases receiving open enterodialysis (Open Group) in the same period. The operating time, intra-operative blood loss, incidence of complications, postoperative recovery time of bowel movement and length of hospital stay of the two groups were compared, respectively. Results In the Laparoscopic Group operation was successfully accomplished in 23 cases while a conversion to open surgery was required in 2 cases. Of the Laparoscopic Group and the Open Group, the operation time was (58.3?8.1) min and (84.0?7.5) min (t=11.383, P=0.000), respectively; the intra-operative blood loss was (31.4?5.1) ml and (192.6?26.4) ml (t=29.995, P=0.000), respectively; the postoperative hospital stay was (4.1?1.4) days and (9.7?2.0) days (t=11.413, P=0.000), respectively; the postoperative recovery time of bowel function was (19.6?2.2) hours and (49.0?8.8) hours (t=16.207, P=0.000), respectively and the postoperative complications were seen in 1 case and 9 cases (?2=6.960, P=0.008), respectively. Conclusions Compared with open enterodialysis, laparoscopic enterodialysis has advantages of short operation time, less blood loss, rapid recovery and fewer complications.

Objective To evaluate the role of laparoscopic ultrasonography (LUS) in difficult place laparoscopic hepatectomy of the right liver.Methods The data of 7 patients undergoing laparoscopic hepatectomy with tumor in the difficult location of the right liver in our hospital between Jun 2015 and Aug 2017 were retrospectively analyzed.LUS was used during all the operations in order to investigate the anatomy of the operations,determine the tumor stage and guide the incision margin of tumor.It was conventionally used to detect the relationship between the lesions and peripheral intrahepatic vessels and ducts.Results Seven cases underwent successful laparoscopic hepatectomy.The mean operative time was (121 ± 50) min,average intraoperative blood loss was (301 ± 122) ml,and there was no operative mortality.Mean hospital stay was (7.1 ± 1.2) d.One suffered biliary leakage and was cured by conservative treatment.Conclusions Laparoscopic ultrasound can determine tumor location and guide the operative route,increasing safety of laparoscopic hepatectomy.
