Application of laparoscopic eversion fixation of cyst wall in the treatment of simple hepatic cys / 中华肝胆外科杂志

Objective:To investigate the clinical efficacy of laparoscopic eversion fixation of cyst wall in the treatment of simple hepatic cyst.Methods:The clinical data of 27 patients with simple hepatic cyst who underwent laparoscopic cyst eversion fixation in Department of Hepatobiliary Surgery, the First Affiliated Hospital of Henan University of Science and Technology from January 2017 to December 2020 were retrospectively analyzed. There were 8 males and 19 females, aged (60.6±9.0) years. Methods of operation, operation time, pathological results, incisional pain, peritonitis, bleeding or infection in the sac were analyzed. Recurrence was followed up by outpatient or telephone review.Results:Laparoscopic eversion fixation of cyst wall was successfully performed in all patients. Twelve cases (44.4%) were fixed in the falciform ligament, and 15 cases (55.6%) were fixed on the liver surface. The operative time was (119.3±44.3) min. The histopathologic results of the capsular wall were all fibrous connective tissue coated with endothelial cells, and no tumor cells were found. After the operation, 25 cases (92.6%) of light clear cyst fluid were not cultured for bacteriology, and 2 cases (7.4%) of turbid cyst fluid bacteriology culture was negative. There were 11 cases (40.7%) with right upper abdominal incision pain on the first day after surgery, and the pain disappeared after proper treatment without bile leakage, peritonitis, bleeding or infection. All patients were followed up for 18 to 36 months, with a median follow-up time of 24 months, and no cyst recurrence was reported.Conclusion:Laparoscopic eversion fixation of cyst wall is a good method for the treatment of simple hepatic cyst.

Research progress of Laennec capsule in liver surgery / 中华肝胆外科杂志

With the rapid development of laparoscopic hepatectomy, more and more hepatic surgeons have been paid attention to Laennec capsule. Based on the relevant literature in recent years, this paper reviewed the discovery, development, histological characteristics, distribution on the surface of the liver and the application of Laennec capsule in anatomic hepatectomy, so as to provide a reference for further discussion of the capsule approach of the laparoscopic anatomic hepatectomy.

Reoperation for patients with postoperative recurrent simple hepatic cysts / 中华肝胆外科杂志

Objective To study the efficacy of the deroofing-fixation operation for postoperative recurrent simple hepatic cysts (RSHC).Methods 21 patients who developed postoperative RSHC underwent the deroofing-fixation operation at the First Affiliated Hospital,Henan University of Science & Technology from August 2012 to August 2016.The data were analyzed retrospectively.Results The recurrent sites varied and included S6,7 (n=9),S7 (n=5),S8 (n=3) and S7,8 (n=4).The first operations for all these patients were either laparoscopic fenestration or windowing decompression.The recurrence time ranged from 4 to 13 months (average 6 months) after the first operation.All these patients were reoperated using the deroofing-fixation method,i.e.taparotomy,cyst deroofing and cyst edge fixation to the right hepatorenal ligament (n =9),or to the hepatic falciform ligament (n =12).All these patients were followed up for 11 to 60 months after the reoperation,and no recurrence was found.Conclusion The deroofing-fixation is an efficacious operation for post-operative RSHC.
