Comparative study of pain in women submitted to conventional laparoscopic cholecystectomy versus single-port laparoscopic cholecystectomy.

PURPOSE:: To evaluate postoperative pain in patients submitted to conventional laparoscopic cholecystectomy with four ports versus single-port laparoscopic cholecystectomy with only one port. METHODS:: Twenty-one patients were included in the conventional laparoscopic cholecystectomy group and 19 other patients in the single-port laparoscopic cholecystectomy group. A VAS was used for the assessment of postoperative pain at three time points. Differences were considered statistically significant when p<0.05. RESULTS:: Intergroup analysis showed no significant difference in VAS scores between the conventional laparoscopic cholecystectomy and single-port laparoscopic cholecystectomy groups at any of the time points studied. CONCLUSION:: This study found no significant difference in postoperative pain between the two groups.

Estudo anatômico de bolsões adiposos na região hipogástrica / Anatomic study of pockets areas in the hypogastrium

INTRODUÇÃO: Nas lipodistrofias da parede abdominal anterior, fatores genéticos, aumento de peso, idade e lasseamento da musculatura, de forma isolada ou associada, determinam alterações estéticas generalizadas ou localizadas no epigástrio, no hipogástrio ou, mesmo, em ambas as regiões. O objetivo deste estudo é descrever os limites, a disposição, as relações anatômicas das bolsas adiposas no hipogástrio com as estruturas vizinhas e suas dimensões. MÉTODO: Foram dissecadas 57 peças anatômicas de pacientes submetidas a abdominoplastia, em que o hipogástrio foi ressecado em monobloco. Além disso, foi realizada dissecção da parede abdominal anterior em 8 cadáveres. Em todas as peças, a camada lamelar foi ressecada, mantendo-se a derme-epiderme, a camada areolar e a fáscia superficial íntegras. RESULTADOS: Em todas as peças, foram observados dois cúmulos adiposos na camada areolar bilateralmente, simétricos, em forma de bolsa e de coloração peculiar. Essas bolsas foram também analisadas em relação aos tecidos cutâneos vizinhos: pele, fáscia superficial, camada profunda de gordura. CONCLUSÕES: A camada lamelar foi considerada estrutural como base da pele, pela sua fina espessura, e a camada areolar apresentou acúmulos e volumes variáveis de tecido adiposo nas diversas regiões do corpo, sem limites precisos, particularmente observados nas dissecções da parede abdominal inferior, pela sua elasticidade, pelo volume e pela coloração.

BACKGROUND: In lipodystrophies of the anterior abdominal wall, variables such as genetic factors, weight gain, age, and loss of muscle tone, either alone or in combination, determine generalized aesthetic changes or changes localized in the epigastrium, hypogastrium, or both. The aim of this study was to describe the limits, distribution, and dimensions of fat bags in the hypogastrium, as well as their anatomic relationships with the neighboring structures. METHODS: Fifty-seven anatomical specimens were dissected from patients undergoing abdominoplasty, during which the hypogastrium was resected en bloc. Moreover, the anterior abdominal wall was also dissected in 8 cadavers. In all samples, the lamellar layer was resected, keeping the dermis-epidermis, areolar layer, and superficial fascia intact. RESULTS: In all specimens, 2 symmetrical adipose clusters were observed bilaterally in the areolar layer, which were in the shape of a bag and had peculiar coloration. These bags were analyzed in relation to their neighboring tissues: the skin, superficial fascia, and deep fat layer. CONCLUSIONS: The lamellar layer was considered as a structural base of the skin, owing to its thinness. The areolar layer showed accumulations and varying amounts of fat in the various body regions without precise limits, which were particularly observed in dissections of the lower abdominal wall and identified by their elasticity, volume, and coloration.
