Efficacy of peritoneal drainage in very-low-birth-weight neonates with Bell's stage II necrotizing enterocolitis: A single-center retrospective study.

BACKGROUND: Currently, pediatric surgeons are challenged by a lack of consensus on the optimal management strategy (conservative or surgical) for children with Bell's stage II necrotizing enterocolitis (NEC). AIM: To evaluate the clinical efficacy of peritoneal drainage in very-low-birth-weight (VLBW) neonates with modified Bell's stage II NEC. METHODS: This was a retrospective analysis of 102 NEC (modified Bell's stage II) neonates born with VLBW who were treated at the Fujian Children's Hospital (Fujian Branch of Shanghai Children's Medical Center) between January 2017 and January 2020; these included 24 cases in the peritoneal drainage group, 36 cases in the exploratory laparotomy group, and 42 cases in the conservative treatment group. RESULTS: The general characteristics were comparable in the three groups (P > 0.05). Compared with conservative treatment, peritoneal drainage was associated with significantly shorter fasting time, abdominal distension relief time, fecal occult blood (OB) negative conversion time, and reduced hospital length of stay (HLOS) (P < 0.05 for all). Despite some advantages of peritoneal drainage over conservative treatment in terms of cure, conversion to laparotomy, intestinal perforation, intestinal stenosis, and abdominal abscess rates, the differences were not statistically significant (P > 0.05). Compared to exploratory laparotomy, the fecal OB negative conversion time was significantly shorter in the peritoneal drainage group (P < 0.05); similarly, the exploratory laparotomy group showed longer fasting time, abdominal distension relief time, HLOS, and higher complication rate compared to peritoneal drainage group, but the between-group differences were not statistically significant (P > 0.05). CONCLUSION: Peritoneal drainage, an easy-to-operate procedure, can improve the clinical symptoms of VLBW neonates with Bell's stage II NEC and help reduce the HLOS.

Laparoscopic-assisted Soave procedure for Hirschsprung disease: 10-year experience with 106 cases.

BACKGROUND: The purpose of this study was to summarize the clinical experience and 10 year follow-up results of laparoscopic assisted Soave procedure for the treatment of long-segment Hirschsprung disease (HD). METHODS: From January 2010 to February 2020, 106 children with long-segment HD participated in this study. The laparoscopic-assisted Soave procedure was performed for the treatment of long-segment HD. The follow-up time was two weeks, one month, and three months after the operation, and then every six months to one year. RESULTS: The operation was successful for all 106 children. All patients were discharged 5-7 days after the operation. The median time in surgery was 150 (100-190) minutes, and the median volume of bleeding was 6 (3-10) ml. The short-term postoperative daily defecation frequency was 4-11 times, 3-7 times within 6 months, and 2-3 times after 6-12 months. Postoperative complications included anastomotic leakage in two cases, perianal dermatitis in 13 cases, anastomotic stenosis in four cases, adhesive bowel obstruction in two cases, enterocolitis in 16 cases, soiling in 11 cases, and constipation recurrence in three cases. CONCLUSIONS: The laparoscopic-assisted Soave procedure is a safe and effective surgical method for treating long-segment HD, and it causes little trauma or bleeding and has a fast postoperative recovery. Yet some complications may occur. Preoperative diagnosis, intraoperative and postoperative standardized processing can reduce the postoperative complications.

Mini-laparoscopic pyeloplasty to treat UPJO in infants.

PURPOSE: The aim of this study was to investigate the safety and clinical efficacy of mini-laparoscopic pyeloplasty in treating ureteropelvic junction obstruction (UPJO) in infants. MATERIAL AND METHODS: We retrospectively analysed the clinical data of 66 infants with UPJO from January 2013 to August 2018 at our hospital. They were divided into the laparoscopic surgery group (group A) and the open surgery group (group B), depending on the surgical method. RESULTS: The bleeding volume, analgesia duration, postoperative hospitalization duration, and incision length in group A were significantly less than those in group B (p < .05). The incidence of incision dehiscence was 0% in group A and 11.7% in group B (p = .045). At the postoperative follow-up, the incidence of anastomotic stenosis was 6.2% in group A and 5.9% in group B (p = .719). The anteroposterior diameter and glomerular filtration rate were significantly improved at the one-year follow-up, but there was no significant difference between the groups (p > .05). CONCLUSIONS: Mini-laparoscopic pyeloplasty to treat UPJO in infants has the same early clinical efficacy and safety as open surgery, and this procedure has the advantages of fewer incisions, less pain, quicker recovery, and better cosmetic outcomes.

Clinical Efficacy of an Indwelling Transanal Tube for the Prevention of Anastomotic Leakage After Hirschsprung's Disease: A Single Center Experience with Chinese Patients.

Background: The aim of this study was to investigate the clinical effectiveness of an indwelling transanal tube for the prevention of anastomotic leakage (AL) after a radical operation for Hirschsprung's disease (HD). Methods: We retrospectively analyzed the clinical data from 158 patients who had undergone laparoscopic-assisted Soave procedures for HD at our hospital from May 2015 to May 2019. Patients were divided into two groups depending upon whether the anal drainage tube was retained or not retained: an indwelling group (group A, n = 86) and a no-indwelling group (group B, n = 72). Results: All 158 children had a successful operation by a laparoscopic technique. There was no significant difference in the duration of the operation, the length of the incision, the amount of bleeding, or the postoperative hospitalization time between the two groups. Compared with the no-indwelling group, maintaining the transanal tube had significant advantages for preventing incidences of AL (P < .05). The 4-year follow-up showed that the incidence of postoperative enterocolitis with the indwelling transanal tube was significantly lower than in the group without the drainage tube (P < .05). Conclusions: The laparoscopic-assisted Soave procedure with an indwelling transanal tube is a safe and feasible method for the treatment of HD in children. This method can not only drain intestinal contents but also reduce the occurrence of AL.
