Background: Testicular atrophy is recurrent after orchidopexy for intra-abdominal cryptorchidism due to damage to vessels. Fowlers-Stephens and Shehata methods proposed staged orchidopexy, but are still associated to a rate of atrophy greater than 10%. Purpose: We set out to present a new technique that preserves testicular vessels. Our study is aimed at investigating testicular vitality after surgery. Patients and Method: We reviewed files of boys who underwent orchidopexy for 2 years in our department. Those who have been operated for intra-abdominal cryptorchidism with the new technique and aged between 6 months and 14 years old were included in our study. We excluded boys who have been operated before 6 months and after 14 years old and those who did not respect their follow-up plane. Ultrasound (US) outcomes were used to measure testicular volumes and blood flow at each postoperative visit. The Sample population was divided into group A and group B representing testes that were followed respectively for 12 and 24 months. Results: 22 boys with 25 testes were included in our study;11 testes in group A and 14 testes in group B. In each group, we noted a significant difference of UDT volumes from the third month after surgery with respective P-values 0.05. There was no statistical difference between UDT and contra lateral testes volumes 12 months after surgery in group A and 24 months in group B with respective P-values of 0.07 and 0.72. All volume differential indexes were Conclusion: This method offers a new perspective in performing safe orchidopexy for intra abdominal undescended testes.

Introduction: Fallopian diseases are often implicated in female infertility. Several radiological and surgical explorations have been proposed in order to evaluate the severity of lesions found in utero-adnexal pathology. Among tools that are used to investigate such pathologies, we have ultrasound, hysterosalpingography and endoscopy. But, in many developing countries like Cameroon, the usage of endoscopy in gynecology is not yet known by many practicians. The objective of our study was to show the interest of endoscopy in the diagnosis of fallopian tube pathologies. Methodology: We conducted a cross-sectional and descriptive study from March 1st, 2017 to May 31st, 2017 at the Gyneco-Obstetrics and Pediatric department of our Hospital. We included all women who presented infertility and underwent ultrasound, hysterosalpingography (HSG) and endoscopy at the Yaoundé Gyneco-obstetrics Hospital. We analyzed epidemiological parameters, clinics, ultrasound, hysterosalpingography and endoscopic finding. We used Cohen’s Kappa test to determine the correlation between HSG/endoscopy and ultrasound/endoscopy in the diagnosis of fallopian tube pathologies. The threshold was significant for a K-value > 0.20. Results: We got a sample of 156 women;the mean age was 32.6 ± 4.5 years. The Secondary infertility dominated in 66.7% of cases;31.1% of women presented a past medical history of sexually transmitted infections and 41.7% did abortions before. Endoscopic lesions were dominated by a fallopian obstruction in 54.5% of cases, 8.3% of adhesions, 33.9% of women presented uterine myomas, 37.8% of ovarian cysts and 1.3% of pelvic endometriosis. The K-values between HSG and endoscopy for distal and proximal tube obstructions were significant with respective thresholds of 0.25 and 0.30. The K-value between ultrasound and endoscopy was not significant with a threshold of 0.015 for the tubal hydrosalpinx. Conclusion: Endoscopy assessment appears as the most efficien

Gradual Bedside Reduction of Gastroschisis in a Resource Constrained Setting: Preliminary Results from 32 Cases

Introduction: Gastroschisis is one of the neonatal pathologies with bad prognosis in developing countries due to a lack of equipment. We aim to report one way of managing this malformation that could be practised everywhere, constituting an alternative approach to surgery in poor areas. Patients and Methods: This observational and descriptive study included newborn babies with gastroschisis who underwent gradual bedside reduction at the Paediatric Surgery Department of the Yaounde Central Hospital. Results: Our cohort was constituted by 32 newborn babies with a mean age of 18.12 hours on admission. The Lefort type 2 was the most frequent in 81.25% of cases. The mean time for oral feeding after complete reduction was 17.4 days and the duration of hospital stay was 24.91 days. Survival rates were at 40.63%, with a residual hernia after healing in 38.46% of cases. Conclusion: Despite the high rate of mortality, gradual reduction of gastroschisis at the bedside seems to be an opportunity for resource constrained areas and can be an alternative solution to surgery.
