This study aimed to evaluate the safety and effectiveness of circumumbilical incision (CUI) for neonates requiring intestinal anastomosis. Seventy neonates requiring intestinal anastomosis at our institution between 2003 and 2020 were included in this retrospective case-control study. Patients were classified into the CUI (25 patients: 36%) and transverse incision (TI) groups (45 patients: 64%). Postoperative complications and surgical outcomes were compared between the two groups. Intestinal perforation at the non-anastomotic site occurred significantly more often in the CUI group than in the TI group (3 patients: 12%, and 0 patients: 0%, respectively (p = 0.042)). There were no between-group differences regarding anastomotic leakages, anastomotic strictures, time to enteral feeding, operative time, and blood loss. Neonatal intestinal surgery employing CUI might be associated with increased intestinal perforation at the non-anastomotic site. Hesitating to enlarge the skin incision to maintain favorable cosmetic outcomes might cause severe injury to the delicate neonatal intestine during the surgical procedure owing to the restricted surgical field. When performing CUI, we suggest that the skin incision should be extended without hesitation whenever there is difficulty in manipulating the intestine. [ABSTRACT FROM AUTHOR]

We reviewed the outcomes of meconium peritonitis and evaluated the safety and feasibility of primary radical surgery for meconium peritonitis. A total of 21 cases of meconium peritonitis between 2006 and 2020 were retrospectively reviewed. The patients were classified into two groups based on the type of surgery: group I (primary radical surgery, n = 16) and group II (multistage surgery; drainage only or ileostomy, followed by elective surgery, n = 5). Patient backgrounds and surgical outcomes were compared between the two groups. The term of prenatal diagnosis, preoperative white blood cell count, and preoperative catecholamine use were not significantly different between the two groups. Group I included more mature neonates than group II (gestational age at birth, 35w1d vs 30w1d, p = 0.02; birth weight, 2.5 kg vs 1.1 kg, p < 0.01). Preoperative C-reactive protein was significantly lower in group I (0.37 mg/dL vs 2.8 mg/dL, p < 0.05). Operation time, blood loss, time to enteral feeding, and complication rates were not significantly different between the two groups. The surgical outcomes of primary radical surgery were comparable to those of multistage surgery, although the patients' backgrounds were different. Our strategy of selecting one-stage or multiple-stage surgery for treatment of meconium peritonitis, depending on the patient's general condition and degree of intestinal ischemia, was reasonable.

Massive splenomegaly and hypersplenism in patients with biliary atresia after Kasai portoenterostomy were treated with partial splenic embolization or total splenectomy. We performed partial splenectomy to reduce the complications of partial splenic embolization and avoid overwhelming post-splenectomy infection. This study aimed to evaluate the long-term effects of partial splenectomy for hypersplenism on postoperative liver and spleen function in patients with biliary atresia. Among jaundice-free patients with biliary atresia who underwent Kasai portoenterostomy between January 1992 and December 2012, 15 underwent partial splenectomy for massive splenomegaly and hypersplenism at our institution. Changes in the laboratory data 10 years post partial splenectomy were retrospectively investigated, and these along with the latest data were measured. A total of four patients (27%) required living-donor liver transplantation after partial splenectomy, a proportion similar to those who did not undergo partial splenectomy. Compared to the preoperative baseline, the platelet counts were significantly higher at 1 and 3 years after surgery (p < 0.05). Aspartic aminotransferase-to-platelet ratio index was significantly lower at 1, 7, and 10 years after partial splenectomy (p < 0.05). No further surgeries were required for hypersplenism after partial splenectomy over 10 years, and there were no cases of overwhelming post-splenectomy infection after partial splenectomy. Partial splenectomy is safe and effective for the treatment of hypersplenism with biliary atresia over a long time period. It could be considered as an alternative to partial splenic embolization as it can suppress hypersplenism for a long time and induces fewer postoperative complications. [ABSTRACT FROM AUTHOR]
