Several risk factors associated with early relaparotomy after liver transplantation include pediatric end-stage liver disease (PELD) score, warm ischemia time (WIT), and cold ischemia time (CIT). Our study investigated the incidence and indications of early relaparotomy in postoperative pediatric LDLT recipients and compared the outcomes with patients who did not require relaparotomy.MethodsA retrospective cohort study of pediatric LDLT recipients from Cipto Mangunkusumo Hospital, Jakarta, Indonesia, was collected from 2010 to August 2022. Indications for early relaparotomy were investigated. Factors analyzed in the early relaparotomy group compared with the nonrelaparotomy group included intraoperative blood loss, surgery duration, CIT, WIT, and PELD score.Re...

This study aims to present patients’ characteristics who had undergone oncological reconstructive surgery at the Department of Surgical Oncology, Dharmais National Cancer Center. Methods: This descriptive study identified patients’ characteristics who underwent oncological reconstructive surgery, their cancer types, and their therapies. All data were obtained from surgery registration and medical records from January 2019 to January 2020. Data were then presented in number and percentage.Results: A total of 174 patients had undergone oncological reconstructive surgery within one year. The mean age of all patients was 48.2 ± 16.7 years old. Most patients were female (72.1%), with breast cancer making up most cases (43.7%). Most of the participants also underwent mastectomy (42.1%), which was later followed by various reconstruction types. Sixty pa...

In all cases, less than 1% found as the cause of intestinal obstruction. However, delayed treatment of internal hernia may lead to necrosis of the intestines. Neonates with congenital heart disease may be at increased risk of morbidity and mortality than another concurrent disease. A male infant was delivered with a Cesarean section due to a congenital disorder of umbilical hernia, ventricular septal defect, and aortic transposition. The infant was born full-term with a 2,515 g birth weight and 3, 5, 7 APGAR score, positive ventilation, and intubation proceeded. Prostaglandin E1 10 mcg/kg/minute, packed blood cell, and thrombocyte concentrate was administered preoperatively. The patient underwent laparotomy for intestinal resection on day-3; the necrotic intestine was found starting 70 cm from ligament of Treitz to midsection of the transverse colon. Postoperatively, the stoma was vital, and we noted its production. The infant died one day1...

Oral Spermine Supplementation in Gestated Rabbit: A Study on Villi Height of Immature Intestines

Postnatal oral spermine has been shown in studies to improve intestinal maturation in rats and piglets. This study aimed to find out the efficacy of spermine in rabbits during gestation.Method: An experimental study was done in an unblinded, randomized manner on those treated with and without spermine administration. A morphological examination of hematoxylin–eosin-stained villi was performed under a light microscope with a focus on villi height. Data were subjected to analysis.Results: The median of the spermine-treated group was found to be higher at 24, 26, and 28 days than the non-spermine group, but was not significantly different.Conclusion: Oral spermine supplementation during gestation might improve intestinal villi height in immature rabbit intestines.

Bleeding small bowel cavernous haemangioma following blunt trauma to the abdomen presenting as subacute intestinal obstruction in a child

Her normal vital signs masked the presence of intestinal bleeding. An incidental finding at surgery of a haematomatous polypoid vascular growth of the ileum was subsequently confirmed to be cavernous haemangioma of the small bowel. Surgical resection was curative in this patient.

In cases of impalpable testes, ultrasound is often used to find the testis, which frequently provides false-negative results. Recently, laparoscopy has become popular in the management of impalpable testes. Methods: Retrospective study of all children with impalpable testes presenting for laparoscopy between August 2007 and July 2011 who had undergone ultrasound examinations without localizing the testes was conducted and the role of laparoscopy in diagnosing impalpable testes was evaluated. Results: Twenty-three patients presented with impalpable testes for laparoscopy. All patients underwent ultrasound examinations in which the testes could not be identified. Of the 23 patients, Five patients were found to have palpable testes in the superficial inguinal pouch under anesthesia and proceeded to conventional open exploration during which the testes were brought into the scrotum. Eighteen patients were found to have impalpable testes in an evaluation under anesthesia (EUA) and proceeded to laparoscopy. Twelve patients were found to have intra-abdominal testes and underwent laparoscopic-assisted orchidopexy. Three patients Conflicts of interest: The authors declare that they have no financial or non-financial conflicts of interest related to the subject matter or materials discussed in the manuscript.

We report a novel method of managing focal isolated perforation in necrotizing enterocolitis by using diagnostic laparoscopy to localize the site of perforation and by making a microincision over the perforation to perform exteriorization or limited resection and primary anastomosis. Methods: We included low-birth weight infants presenting with sudden clinical deterioration and pneumoperitoneum. Patients with gross abdominal wall signs were excluded on the probability that they had extensive disease. Diagnostic laparoscopy was performed using a 3.5-mm trocar and 1.9mm telescope. A 1-cm incision was made over the site of perforation, and local surgical debridement was performed. Results: There were 3 extremely low-birth weight patients (580, 700, and 780 g) and 1 larger infant (1.6 kg). In all cases, an isolated perforation was detected. None had widespread disease. The 3 smaller infants had exteriorization and enterostomies. The larger patient had resection and primary anastomosis. All patients recovered uneventfully. Conclusion: Diagnostic laparoscopy can be safely performed in extremely low-birth weight infants. It allows precise identification of the site of perforation to perform a limited microlaparotomy at this site, significantly reducing the surgical trauma of extensive bowel handling. We report a novel method of managing this vexing problem.

We report our experience. Method: A retrospective study was performed of all children undergoing hypospadias surgery from July 2007 to July 2011. Octyl cyanoacrylate was used for skin closure after placing a few sutures to align the skin edges. No other dressing was used. A urethral stent, if used, was glued to the penis and removed after one week. Results: Seventy two procedures were performed on 37 patients. Eight distal hypospadias (22%) underwent single stage repair. Seventeen (46%) underwent staged repair for severe hypospadias, and twelve (32%) "hypospadiac cripples" underwent various salvage procedures. One patient (1/72) had partial dehiscence, and one stent dislodged. There were no wound infections. Four (4/25) tabularized urethroplasties developed a fistula (16%). Conclusion: Octyl cyanoacrylate is easy to apply on difficult hypospadias contours. It forms a strong, waterproof adhesive bond which separates from epithelial surfaces in 7 to 10 days and makes it an effective urethral stent fixator and an ideal dressing for hypospadias surgery.
