Laparoscopic liver surgery: 8 years of multicenter Spanish register.

BACKGROUND: To present the data of laparoscopy in liver surgery and to assess the real indications and outcomes of this kind of approach. METHODS: From February 2000 to March 2008, a prospective study was performed on 182 patients from 15 Spanish surgical centres. RESULTS: A total of 308 lesions was collected. The mean age was 57 years old, and 61.5% were female. Among patients with cystic lesions we found: 45 simple cysts, 19 policystic diseases, 12 hydatidic cysts and 2 cystoadenomas. Among solid lesions (n = 104), we found 34 patients with benign pathology (12 focal nodular hyperplasia, 10 adenomas, 7 haemangyomas and 5 other lesions) and 70 with malignant pathology (38 metastases, 29 hepatocellular carcinomas, 2 cholangiocarcinomas and 1 lymphoma). The global rate of conversion was 8.8%. The global morbidity rate was 14.8%, and 5 of them required re-intervention. CONCLUSIONS: Nowadays there are strong criteria for patients being submitted to laparoscopy procedures based both on type and location features. The postoperative morbidity rate is low, also for hepatocellular carcinoma in cirrhotic liver. In case of malignant pathology, we think the use of ultrasonography is mandatory to obtain a free margin, which implies a long-term survival rate.

[Analysis of the Spanish National Registry of Laparoscopic Pancreatic Surgery]. / Análisis del Registro Nacional Español de la Cirugía Laparoscópica del Páncreas.

INTRODUCTION: The reported experience with laparoscopic pancreatic surgery remains limited to case reports or small series of patients. A recent European multicenter study has allowed the limits and results of this technique to be known. This article presents an analysis of the results of the Spanish National Registry of Laparoscopic Pancreatic Surgery. MATERIAL AND METHODS: A total of 132 patients with lesions in the left pancreas were included in this series. The final diagnosis included 42 neuroendocrine tumors, 40 cystic neoplasms, 24 cysts and pseudocysts, 8 inflammatory tumors, 8 ductal carcinomas, 7 intraductal papillary mucinous tumors, 1 acinar carcinoma and 2 solid pseudopapillary tumors. RESULTS: The conversion rate was 9.7%. Tumor enucleation was performed only in patients with insulinomas. The most frequent technique was spleen-preserving distal pancreatectomy. There were no postoperative deaths. The overall rate of postoperative pancreatic-related complications was 16%. CONCLUSIONS: Although only a few Spanish hospitals participated in the registry, a greater number of hospitals are expected to enroll patients in the very near future.

Análisis del Registro Nacional Español de la Cirugía Laparoscópica del Páncreas / Analysis of the Spanish National Registry of Laparoscopic Pancreatic Surgery

Introducción. En el pasado, la experiencia de la cirugía laparoscópica del páncreas se mantenía limitada a experiencias individuales con un reducido núcleo de pacientes. El reciente estudio multicéntrico europeo ha permitido conocer los límites y los resultados de la técnica. En este trabajo se presenta el análisis de los resultados del Registro Nacional Español de la Cirugía Laparoscópica del Páncreas (RNEP). Material y métodos. Se ha incluido a 132 pacientes con lesiones localizadas en el páncreas izquierdo: 42 tumores neuroendocrinos, 40 neoplasias quísticas, 24 quistes y seudoquistes, 8 tumores inflamatorios, 8 carcinomas ductales, 7 neoplasias papilares mucinosa, 1 carcinoma acinar, 2 tumores sólidos seudopapilares. Resultados. El índice de conversión fue del 9,7%. La técnica de enucleación se realizó tan sólo en pacientes portadores de un insulinoma. La pancreatectomía distal con preservación esplénica fue la utilizada con más frecuencia. La mortalidad fue nula y, como morbilidad, la fístula pancreática apareció en el 16% de los casos. Conclusiones. A pesar de que el número de hospitales españoles es limitado, los resultados obtenidos hacen esperar una mayor experiencia en un futuro próximo (AU)

Conservative treatment of a huge abdominal wall hematoma after laparoscopic appendectomy.

We report a case of a 30-year-old male patient who presented with a huge abdominal wall hematoma 60 minutes after laparoscopic appendectomy. During surgery there had been no sign of abdominal wall bleeding. We found a lateral abdominal wall hematoma caused by rupture of the abdominal epigastric artery after trocar insertion. We conclude that trocar injury is a potentially preventable complication in laparoscopic surgery if certain precautions are taken. Abdominal wall hematoma secondary to injury of an epigastric vessel can be successfully treated with conservative management.

Laparoscopia colorrectal en Canarias. Estudio multicéntrico en 144 pacientes / Colorectal laparoscopy in the Canary Islands. A multicenter study of 144 patients

Introducción. Analizar los resultados a corto plazo de la cirugía laparoscópica colorrectal (CLCR) en Canarias. Material y métodos. Enviamos una encuesta a los hospitales que realizan esta actividad y obtuvimos retrospectivamente datos sobre las variables demográficas, peroperatorias y anatomopatológicas de 144 pacientes intervenidos de CLCR desde mayo de 1993 hasta mayo de 2003. Resultados. Se intervino quirúrgicamente a 65 varones y 79 mujeres, 68 (47,2%) en los últimos 16 meses del período estudiado. Se realizaron 126 procedimientos colónicos y 18 rectales. El procedimiento más realizado fue la sigmoidectomía, con 85 casos (59%). El adenocarcinoma, con 73 casos (50%), fue el diagnóstico más habitual, y la diverticulosis, con 36 casos (25%), fue el segundo en frecuencia. Los valores medios de las variables estudiadas fueron: índice de masa corporal medio, 27,3 (rango, 22-35); tiempo quirúrgico, 175 min (rango, 60-255), y pérdidas hemáticas, 183,6 ml (rango, 50-500). La peristalsis se presentó a las 45 h, la dieta oral se inició a las 67 h y la estancia hospitalaria media global fue de 7,8 días (rango, 3-30). Los pacientes que presentaban complicaciones tuvieron una estancia significativamente mayor (14,5 frente a 6,4 días; p < 0,01). Hubo 7 conversiones (4,86%). No se registró ninguna muerte. La tasa de morbilidad global fue del 28%. La complicación precoz más frecuente fue la infección de la herida en 9 ocasiones (6,2%). Se detectaron 5 casos de fuga anastomótica (3,4%). Conclusiones. La CLCR se ha mostrado como una técnica segura y eficaz, y su uso se ha incrementado en todos los centros consultados en el último año. La aparición de complicaciones posquirúrgicas fue el factor que más influyó en la estancia hospitalaria (AU)

Introduction. To analyze the short-term results of laparoscopic colorectal surgery (LCRS) in the Canary Islands. Material and methods. A questionnaire was sent to hospitals performing laparoscopy and retrospective data on demographic, perioperative and pathological variables in 144 patients who underwent LCRS between May 1993 and May 2003 were obtained. Results. Sixty-five men and 79 women underwent colon (n=126) and rectal (n=18) surgery in the last 16 months of the study period. The most frequently performed procedure was sigmoidectomy in 85 patients (59%). The most frequent diagnosis was colon adenocarcinoma in 73 patients (50%), followed by diverticular disease in 36 patients (25%). The mean values of the variables studied were: body mass index, 27.3 (range, 22-35); operating time, 175 min (range, 60-255); blood loss, 183.6 ml (range, 50-500). Peristalsis reinitiated at 45 h; oral diet was introduced at 67 h and the overall mean length of hospital stay was 7.8 days (range, 3-30). The length of hospital stay was significantly longer in patients with complications (14.5 vs 6.4; p <.01). There were 7 conversions (4.86%). There were no perioperative deaths. The overall morbidity rate was 28%. The most frequent early complication was surgical wound infection in 9 patients (3.4%). Conclusions. LCRS has been shown to be a safe and effective technique that has recently increased in the centers surveyed. The factor with the greatest influence on length of hospital stay was the development of postoperative complications (AU)
