ABSTRACT
Background: Odontogenic maxillary sinusitis caused by a foreign body presents diagnostic and therapeutic challenges due to its infrequent occurrence and unique characteristics compared to sinusitis originating from other sources. CaseReport:Illustrating such fact, this report presents the clinical case of a 37-year-old woman referred complaining of pain in the same region where she had extracted her upper right first molar five days before. The intraoral examination revealed the presence of an orifice in the region, suggesting oroantral communication. Imaging exams revealed opacification of the right maxillary sinus and the unexpected presence of a highly radiodense object. With the diagnosis of maxillary sinusitis due to a foreign body established, the surgical approach initially consisted of administering preoperative medication, preceded by access to the maxillary antrum using the Caldwell-Luc technique. The object was found and removed, consisting of a surgical drill. At follow-up there was complete absence of symptoms and complete closure of communication. Conclusion: Cases of odontogenic maxillary sinusitis caused by drill detachment after tooth extraction are fairly uncommon. A thorough clinical evaluation proved to be essential and the Caldwell-Luc access was effective, safe and with good postoperative results, even with the absence of standardized diagnostic and management methods(AU)
Contexto: A sinusite maxilar odontogênica causada por corpo estranho apresenta desafios diagnósticos e terapêuticos devido à sua ocorrência infrequente e características únicas em comparação com sinusites originadas de outras fontes. Relato do Caso: Ilustrando tal fato, este relato apresenta o caso clínico de uma mulher de 37 anos de idade encaminhada com queixa de dor em mesma região que havia extraído o primeiro molar superior direito cinco dias antes. Ao exame intraoral verificou-se a presença de um orifício na região, sugerindo comunicação oroantral. Os exames de imagem revelaram opacificação do SM direito e a inesperada presença de um objeto altamente radiodenso. Com o diagnóstico de sinusite maxilar por corpo estranho estabelecido, a abordagem cirúrgica consistiu inicialmente na administração de medicação pré-operatória, precedida pelo acesso ao antro maxilar através da técnica de Caldwell-Luc. O objeto foi encontrado e removido, consistindo em uma broca cirúrgica. Ao acompanhamento houve ausência completa dos sintomas e total fechamento da comunicação. Conclusão: Casos de sinusite maxilar odontogênica causada por descolamento da broca após extração dentária são bastante incomuns. Uma avaliação clínica minuciosa mostrou-se primordial e o acesso de Caldwell-Luc eficaz, seguro e com bons resultados pós-operatórios, mesmo com as ausências de métodos de diagnóstico e manejo padronizados.(AU)

The retained of a foreign body during a surgical procedure is defined by the forgetting of a material, left by inattention in the body of the patient during this act. It is a rare event but is responsible for high morbidity and mortality. Authors report a retained foreign body incidentally discovered during a caesarean section. The patient had performed an illegal abortion by endo-uterine instrument which was complicated by uterine perforation five years previously. She was pregnant at 37 weeks and presented to the emergency department for bleeding and diagnosed as placenta previa. The antecedent of abortion had not been informed because it is an illegal act in Madagascar. The plastic instrument was in the broad ligament in contact with the ureter and the uterine artery. Caesarean section, the removal of the catheter and postoperative recovery was uneventful. Foreign body retention remains a malpractice and the diagnosis must be made in the face of chronic pain in patients who have undergone surgery.

ABSTRACT
Rarely, surgical clips can migrate into the biliary tract after laparoscopic cholecystectomy and work as a nidus for biliary stone formation. We report a case of the development of a common bile duct (CBD) stone induced by surgical clip in a 57-year-old man who underwent laparoscopic cholecystectomy 10 years ago. On computed tomography, a CBD stone with a metallic material was found, and endoscopic retrograde cholangiopancreatography (ERCP) revealed a CBD stone including a metallic clip. The stone was removed completely by ERCP, and the surgical clip was found along with the stone.

ABSTRACT
PURPOSE: Use of bipolar electocoagulation devices becomes popular in the laparoscopic surgical field. However, several studies comparing energy-based devices for use in performance of mechanical sealing and cutting techniques have reported various results. The aim of this study was to evaluate feasibility and efficacy of new commercially available bipolar electocoagulation devices: EnSeal(TM) device (Ethicon Endo-Surgery, Cincinnati, OH, USA) by comparison with LigaSure(TM) atlas 5 mm (COVIDIEN, Boulder, CO, USA), for use in performance of coagulation and cutting techniques during performance of laparoscopic colorectal cancer surgery. METHODS: Between June 2010 and February 2011, 50 consecutive patients who underwent curative laparoscopic surgery for right colon cancer or rectal cancer were enrolled. Time and number of device activations were compared during omentectomy in cases of right colectomy and mesorectal trimming procedure in cases of anterior resection. Pathologic data and short-term clinical outcomes were also compared. RESULTS: No significant differences in terms of clinicopathologic comparison were observed between the EnSeal and LigaSure groups. No significant difference in mean operative time (207.6+/-45.3 vs. 198.9+/-57.2; p=0.558), mean time of omentectomy (11.0+/-4.5 vs. 12.6+/-8.6; p=0.293), mean time of m esorectal trimming (18.6+/-10.0 vs. 16.1+/-6.9; p=0.418), mean number of device activations during omentectomy (43.5+/-10.2 vs. 51.6+/-39.2; p=0.586), and mean number of device activations during performance of mesorectal trimming (44.8+/-22.3 vs. 49.1+/-23.7; p=0.597) were observed between the two groups. CONCLUSION: Bipolar electocoagulation devices were adapted for use in laparoscopic surgery, resulting in reduced operative time and blood loss. EnSeal(TM) Device and LigaSure(TM) atlas 5 mm were useful during performance of sealing and cutting techniques in laparoscopic colorectal cancer surgery.
