Laparoscopic herniorrhaphy in children with acute inflammatory diseases of the abdominal cavity
Institutul de CercetÄri ÈtiinÈifice Ăźn Chirurgia PediatricÄ, Universitatea NaÈionalÄ de CercetÄri Medicale âN.Pirogovâ,
Moscova, Rusia, Al XII-lea Congres al AsociaÈiei Chirurgilor âNicolae Anestiadiâ din Republica Moldova cu participare internaÈionalÄ 23-25 septembrie 2015Introducere: PrezenÈa unui proces inflamator-distructiv acut Ăźn cavitatea abdominalÄ este pe larg consideratÄ ca o
contraindicaÈie pentru herniorafia laparoscopicÄ simultanÄ.
Material Èi metode: Ăn perioada 2010-2012, 240 de copii cu vĂźrsta 5-14 ani, au fost spitalizaÈi cu manifestÄrile clinice ale
abdomenului acut Èi au fost supuÈi intervenÈiilor chirurgicale urgente. Ăn timpul laparoscopiei la 29 pacienÈi (18 bÄieÈi Èi 11 fete) a
fost depistat processus vaginalis persistent (PVP): Ăźn 25 de cazuri unilateral Èi Ăźn 4 cazuri - bilateral. NouÄsprezece copii din
acest lot au fost diagnosticaÈi cu formele distructive ale apendicitei acute (Ăźn 6 cazuri complicate cu peritonitÄ localÄ), 5 â cu
pelvioperitonitÄ, 4 â cu limfadenitÄ mezentericÄ acutÄ Èi 1 copil â cu apoplexie ovarianÄ. La toÈi pacienÈii au fost efectuate
intervenÈii simultane â asanarea focarului inflamator Èi ligaturarea subcutanatÄ endo-asistatÄ (SEAL) a PVP.
Rezultate: Nu a fost Ăźnregistrat nici un caz de conversie. DupÄ intervenÈia de asanare a focarului inflamator (apendicectomie,
rezecÈie de ovar, etc.) a fost efectuatÄ SEAL conform metodei modificate de autori. Durata SEAL nu a depÄÈit 6 minute pentru
hernia unilateralÄ Èi 9 minute Ăźn cazuri bilaterale. Postoperator toÈi copii au primit un tratament standard. Ăn toate cazurile
evoluÈia postoperatorie a fost favorabilÄ. ComplicaÈii abdominale sau la nivelul canalului inghinal nu au fost Ăźnregistrate.
Examenul ultrasonor Èi testele de laborator au confirmat rezolvarea completÄ a procesului inflamator. ToÈi pacienÈii au fost
externaÈi complet recuperaÈi.
Concluzii: Herniorafia laparoscopicÄ simultanÄ la copiii cu procese acute inflamatorii Ăźn cavitatea abdominalÄ nu este urmatÄ
de elevarea riscului complicaÈiilor postoperatorii.Introduction: The presence of an acute inflammatory and destructive process in the abdominal cavity is commonly a
contraindication to the one-stage laparoscopic herniorrhaphy.
Material and methods: From 2010 to 2012, 240 children, 5-14 years of age, were admitted to hospital with a clinical picture of
acute abdomen and all of them were urgently operated on. During laparoscopy in 29 patients (18 boys and 11 girls) a persisted
processus vaginalis (PPV) was found: unilateral in 25 cases and bilateral in 4 cases. In 19 children from this group destructive
forms of acute appendicitis (in 6 cases complicated by local peritonitis) were diagnosed as well as 5 â pelvioperitonitis, 4 â
acute mesenteric lymphadenitis, and 1 â ovarian apoplexy. All patients underwent simultaneous procedures â both inflammatory
focus treatment and subcutaneous endo-assisted ligation (SEAL) of PPV.
Results: There was no conversion in any case. After the intervention for treatment of inflammatory focus (appendectomy,
ovarian resection, etc.) the SEAL was performed according to our modification. SEAL duration was not more than 6 minutes for
unilateral hernia and 9 minutes for bilateral. Postoperatively, all children received a standard therapy. In all cases the
postoperative period was favorable. Complications in abdominal cavity or inguinal canals were not registered. Ultrasound
examination and blood tests confirmed a complete relief of the inflammatory process. All patients were discharged with full
recovery.
Conclusions: Simultaneous laparoscopic herniorrhaphy in children with acute inflammation in the abdominal cavity does not
increase the risk of postoperative complications
Survey of highly non-Keplerian orbits with low-thrust propulsion
Celestial mechanics has traditionally been concerned with orbital motion under the action of a conservative gravitational potential. In particular, the inverse square gravitational force due to the potential of a uniform, spherical mass leads to a family of conic section orbits, as determined by Isaac Newton, who showed that Keplerâs laws were derivable from his theory of gravitation. While orbital motion under the action of a conservative gravitational potential leads to an array of problems with often complex and interesting solutions, the addition of non-conservative forces offers new avenues of investigation. In particular, non-conservative forces lead to a rich diversity of problems associated with the existence, stability and control of families of highly non-Keplerian orbits generated by a gravitational potential and a non-conservative force. Highly non-Keplerian orbits can potentially have a broad range of practical applications across a number of different disciplines. This review aims to summarize the combined wealth of literature concerned with the dynamics, stability and control of highly non-Keplerian orbits for various low thrust propulsion devices, and to demonstrate some of these potential applications
