Diagnostic validation and development of an algorithm for identification of intussusception in children using electronic health records of Ningbo city in China.

BACKGROUND: Monitoring the risk of intussusception after the introduction of rotavirus vaccines is recommended by the World Health Organization (WHO). Although the validity of intussusception monitoring using electronic health records (EHRs) has been confirmed previously, no similar studies have been conducted in China. We aimed to verify the diagnosis and determine an algorithm with the best performance for identification of intussusception using Chinese EHR databases. RESEARCH DESIGN AND METHODS: Using the Regional Health Information Platform in Ningbo, patients aged 0-72 months from 2015 to 2021 with any related visits for intussusception were included. The algorithms were based on diagnostic codes or keywords in different clinical scenarios, and their performance was evaluated with positive predictive value (PPV) and sensitivity in line with the Brighton guidelines. RESULTS: Brighton level 1 intussusception was confirmed in 2958 patients with 3246 episodes. Fine-tuned algorithms combining the appearance of the relevant ICD-10 codes or the Chinese keyword 'Chang Tao' in any diagnostic reports with the results of enema treatments or related surgeries showed the highest sensitivity, while the highest PPV was obtained by further criteria based on typical radiographic appearances. CONCLUSION: Intussusception could be identified and validated internally using EHRs in Ningbo.

Single-Site Laparoscopic Percutaneous Extraperitoneal Closure Versus Modified Transumbilical Two-Port Laparoscopic Suturing of the Hernia Sac for the Treatment of Pediatric Inguinal Hernia: Comparison of the Outcomes of Two Different Approaches.

OBJECTIVE: To evaluate the surgical outcomes of single-site laparoscopic percutaneous extraperitoneal closure (SLPEC) and modified transumbilical two-port laparoscopic suturing (M-TTLS) of the hernia sac for the treatment of pediatric inguinal hernia (PIH) and determine whether one approach was superior to another. METHODS: From January 2014 to June 2017, a total of 599 children had undergone SLPEC or M-TTLS in our department. SLPEC and M-TTLS were the most frequently performed single-site laparoscopic procedures for PIH in our department, which represented the extraperitoneal and intraperitoneal approaches, respectively. All patients were followed up at the out-patients' clinics and the medical records were reviewed with respect to all operative outcomes. RESULTS: There were 412 patients undergoing SLPEC and 187 patients undergoing M-TTLS, of which 358 hernias were on the right side, 172 on the left and 69 bilaterally. Two hundred and thirty-one unilateral hernias with contralateral patent processus vaginalis underwent contralateral repair at the same session. Mean operation time was 10.81 minutes in unilateral repair and 17.00 minutes in bilateral repairs, respectively. The perioperative complications included minor extraperitoneal hematoma in four (0.44%) patients, recurrence in one (0.11%), hydrocele in five (0.56%), and contralateral metachronous inguinal hernia in three (1.00%). No other complication developed in either group. There was no significant difference of complications between the two approaches except for the longer operation time in M-TTLS. CONCLUSIONS: Both SLPEC and M-TTLS were the safe and effective methods for PIH. The complications were comparable for M-TTLS and SLPEC, but operation time was significantly longer in M-TTLS than in SLPEC.

Is two-port laparoendoscopic single-site surgery (T-LESS) feasible for pediatric hydroceles? Single-center experience with the initial 59 cases.

INTRODUCTION: Although T-LESS is increasingly being used to treat pediatric inguinal hernia, there is no study regarding T-LESS for pediatric hydrocele. OBJECTIVE: To further evaluate the feasibility of T-LESS and present our single-center experience for repair of pediatric hydroceles. STUDY DESIGN: From January 2016 to July 2016, all boys undergoing T-LESS for hydrocele in our institute were retrospectively reviewed. A laparoscope and a needle-holding forceps were introduced at umbilicus. A round needle with silk suture was stabbed through the abdominal wall. The peritoneum around the internal ring was sutured continuously in a clockwise direction. After a complete purse-string suture, a triple knot was performed by using a single-instrument tie technique. The contralateral patent processus vaginalis (PPV) was repaired simultaneously if present. RESULTS: Overall, 59 boys with hydrocele were included (22 on the left side, 32 on the right side, and 5 bilaterally) (Table). During the procedure, all hydroceles were observed with a PPV but the fluid needed to be aspired in 39 boys. A contralateral PPV was present in 24 boys with unilateral hydrocele, and finally 88 repairs were performed. Mean operative time was 18.3 min for unilateral repair and 27.5 min for bilateral repair, respectively. All procedures were uneventful besides a minor injury to the inferior epigastric vessels. After a mean follow-up of 10.7 months, neither recurrence nor other postoperative complication was observed. There were no visible scars on the abdominal wall. DISCUSSION: Compared with open repair of pediatric inguinal hernia and hydrocele, laparoscopic surgery had several advantages, such as exploration of contralateral PPV, identification of rare hernias, diminished postoperative pain, improved cosmesis, faster recovery, and fewer complications. Differing from the laparoscopic retroperitoneal approach, T-LESS included no subcutaneous tissue in the ligature, and its knot was completely in the peritoneal cavity which could radically prevent the severe pain and suture granuloma in the ligated region. Furthermore, the skin incisions after T-LESS were hidden in umbilicus, which could achieve an excellent cosmetic result. By performing T-LESS for pediatric hydroceles, the current study showed very satisfactory results, such as high success rate, minor complication, and excellent cosmesis. However, because of the difficult learning curve of T-LESS, some technical details (e.g. avoiding injury to the spermatic cord, completely suturing the peritoneal folds and reducing disturbance between the instruments) still need to be improved in the future. CONCLUSION: T-LESS appears to be a safe and effective method for repair of pediatric hydroceles.
