Intraoperative cholangiography during elective laparoscopic cholecystectomy: selective or routine use?

PURPOSE: To investigate clinical, laboratory and ultrasonographic parameters in patients with and without preoperative criteria for intraoperative cholangiography (IOC) during laparoscopic cholecystectomy in order to define predictive factors of choledocolithiasis. METHODS: As a criterion for inclusion in the study the patients should present chronic calculous cholecystitis in the presence or absence of any recent clinical, laboratory of ultrasonographic finding suggesting choledocolithiasis, who were therefore submitted to cholangiography during surgery. RESULTS: A total of 243 laparoscopic cholecystectomies with IOC were performed on patients with chronic calculous cholecystitis with or without a preoperative formal indication for contrast examination. Choledocolithiasis was detected in 33 (13.58%) of the 243 patients studied. The incidence of previously unsuspected choledocolithiasis was only one case (1.0%) among 100 patients without an indication for this exam. However, 32 (22.37%) cases of choledocolithiasis were observed among the 143 patients with a preoperative indication for IOC. CONCLUSION: The use of selective cholangiography is safe for the diagnosis of choledocolithiasis. Only 22.37% of the cholangiography results were positive in cases of suspected choledocolithiasis.

Adenocarcinoma primário multicêntrico com 12 focos: relato de caso e revisão da literatura / Multicenter primary adenocarcinoma with 12 foci: case report and literature review

Relata-se caso raro de adenocarcinoma primário multicêntrico sincrônico em intestino delgado, apêndice cecal e intestino grosso, em homem de 82 anos, com quadro de abdome agudo inflamatório. Foi submetido à laparotomia exploradora, observando-se lesão intestinal estenosante e infiltrativa no ângulo hepático e múltiplas aderências entre as alças do intestino delgado. Foi realizada hemicolectomia direita. O estudo anatomopatológico mostrou 12 focos de adenocarcinomas primários comprometendo intestino delgado (oito focos), válvula ileocecal, apêndice cecal e intestino grosso (cólon ascendente e transverso).

A rare case of synchronous multicenter primary adenocarcinoma in the small intestine, cecal appendix and large intestine, in an 82-year-old man with a condition of acute abdominal inflammation, is reported. He underwent exploratory laparotomy, and a stenosing and infiltrative intestinal lesion was seen in the hepatic angle, along with multiple adherences between the loops of the small intestine. Right hemicolectomy was performed. The anatomopathological evaluation showed 12 foci of primary adenocarcinomas affecting the small intestine (eight foci), ileocecal valve, cecal appendix and large intestine (ascending and transverse colon).

Avaliação da positividade da colangiografia peroperatória em pacientes submetidos à colecistectomia laparoscópica eletiva / Assessment of positive perioperative cholangiography in patients undergoing elective laparoscopic cholecystectomy

OBJETIVO: A colecistectomia laparoscópica é o tratamento de escolha para pacientes com colecistopatia calculosa, embora o manejo da coledocolitíase associada ainda permaneça assunto controverso. O presente estudo baseou-se na análise prospectiva de pacientes submetidos à colecistectomia eletiva com colangiografia peroperatória, pretendendo assim avaliar a positividade do exame contrastado das vias biliares em pacientes com colelitíase sem indicação para colangiografia. MÉTODOS: Foram incluídos, no estudo, 100 pacientes cujos parâmetros clínicos, laboratoriais e de imagem feitos até no máximo 10 dias antes da colecistectomia não apresentaram qualquer alteração no pré-operatório e, portanto, considerados pacientes insuspeitáveis para coledocolitíase. As colangiografias foram analisadas e examinadas pela equipe cirúrgica, pelo radiologista e pelos autores deste estudo. Os laudos foram comparados e correlacionados com achados clínicos e laboratoriais prévios dos pacientes. RESULTADOS: A incidência de coledocolitíase insuspeitável no pré-operatório foi de apenas um único caso entre 100 pacientes sem indicação para o exame (1% de positividade). CONCLUSÃO: Com base neste material, pode-se concluir que o emprego da colangiografia seletiva é segura e deve ser empregada no tratamento da colecistite calculosa.

OBJECTIVE: To evaluate the positivity of cholangiography in patients without formal indication of this exam undergoing elective cholecystectomy. METHODS: We included, in the study, 100 patients whose clinical, laboratory and imaging not older than 10 days before the operation showed no change and therefore kept us unsuspicious of choledocholithiasis. The cholangiographies were analyzed and examined by the surgical team, the radiologist and the authors. The reports were compared and correlated with patients' previous clinical and laboratory findings. RESULTS: The incidence of preoperatively unsuspected choledocholithiasis was only one case (1%). CONCLUSION: The use of selective cholangiography is safe and should be used in the treatment of calculous cholecystitis.
