Objectives: Laparoscopic Kasai portoenterostomy (LKPE) has been shown to be a safe and feasible procedure in patients with biliary atresia (BA). The purpose of this study was to investigate the efficacy of modified LKPE (MLKPE) in the treatment of BA. Methods: Data of 58 BA patients undertaken MLPKE from July 2014 to December 2015 were retrospectively analyzed (group B), and compared with that of 43 BA patients received open Kasai portoenterostomy (OKPE) during the same period (group C). In addition, 195 BA patients who had undergone LKPE during May 2009 to June 2014 were also included (group A). Results: All 296 patients enrolled in this study were non-syndromic type III BA. Compared with group A, group B had shorter operative time (ORT) (P < 0.01) and fewer intraoperative blood transfusion (IOBT) (P < 0.05). The conversion rate and cholangitis rate were also significantly lower in group B than that in group A (P < 0.05). The postoperative oral intake resumed (POOR), any postoperative complications (APOC), clearance of jaundice (CJ), 1-year and 3-year survival rate with native liver (SNL) were not significantly different between group A and group B (P > 0.05). The ORT, IOBT, POOR, APOC, CJ, 1-year and 3-year SNL in group B were much better than that of group C (P < 0.05). Conclusion: The MLKPE was associated with good perioperative with ORT, IOBT, POOR, and APOC. The short-term outcomes in MLKPE were no worse than that of OKPE and LKPE. MLKPE can be regarded as a treatment option for BA. [ABSTRACT FROM AUTHOR]

Objective: To summarize and analyze the technique and experience of laparoscopic liver resection (LLR) in children. Methods: From Dec 2015 to Dec 2018, surgical outcomes were evaluated in 30 pediatric patients with liver tumors. LLR was performed in 21 patients, including 15 males and 6 females with a mean age of 7.6 ± 3.8 years (range, 2-13 years) and a mean liver tumor diameter of 7.2 ± 2.0 cm (range, 4-10 cm). During the same period, 9 cases of traditional open liver resection were selected as controls, including 6 males and 3 females with a mean age of 7.0 ± 3.7 years (range, 2-13 years) and a mean liver tumor diameter of 7.5 ± 2.2 cm (range, 4.4-10.0 cm). Results: The mean operation time and mean hepatic inflow occlusion time were longer in the laparoscopic group, with values of 182.3 ± 66.1 minutes and 83.2 ± 38.2 minutes, respectively, than in the open group, with values of 120.0 ± 54.3 minutes and 49.6 ± 26.5 minutes, respectively. There were no significant differences between the two groups in blood loss (164.4 ± 107.4 mL versus 133.8 ± 87.1 mL), blood transfusion volume (102.2 ± 100.2 mL versus 69.2 ± 81.8 mL), and alanine aminotransferase levels 24 hours after surgery (212.0 ± 101.4 IU/L versus 173.3 ± 97.2 IU/L) and 72 hours after surgery (74.0 ± 32.5 IU/L versus 81.7 ± 57.3 IU/L). The average hospital stay in the laparoscopic group (6.2 ± 1.6 days) was significantly shorter than that in the open group (8.2 ± 2.0 days). The children in both groups recovered well after surgery without serious complications. Conclusion: LLR contributes to improved recovery of patients after surgery without increasing the incidence of complication, therefore, LLR is a safe option for liver tumors in children.

Objective: To summarize experiences and discuss the reasons for postlaparoscopic indirect inguinal hernia recurrence in children. Patients and Methods: From June 2008 to June 2013, 6120 laparoscopic inguinal hernia repairs were performed in our hospital involving 5382 males and 738 females. The average age was 3.1 years. When pneumoperitoneum was established, the laparoscopic lens and a clamp were placed into the upper and lower edges of the umbilicus, respectively. Then on the surface projection of the unclosed internal ring, a sled-like needle with suture was circled and tightened on the internal ring at the extraperitoneum. Results: Patients were followed up for between 6 months to 5 years. A total of 21 cases developed recurrent hernia (0.3%). Three main surgical causes of recurrence were concluded: (1) the internal inguinal ring was weak and significantly expanded, especially underneath the internal ring, which led to the peritoneum nearby the internal ring sliding through; (2) a sled-like needle repeatedly perforated the peritoneum, or some of the peritoneum left was unsutured, usually causing a hydrocele; and (3) there was an unexpected release of the ligature around the hernial ring. The majority of recurrent hernias could be cured laparoscopically ( n=18), but a small number needed an open repair ( n=3). Conclusions: Recurrent hernia still appeared postlaparoscopic inguinal hernia in a small number of patients. The main preventive measures were removal of risk factors for hernia and an appropriate surgical approach. [ABSTRACT FROM AUTHOR]
