INTRODUÇÃO: Alterações da função pulmonar após cirurgia abdominal levam à redução do volume pulmonar, prejudicando as trocas gasosas. OBJETIVO: Avaliar os efeitos da cinesioterapia respiratória sobre a função pulmonar e a força muscular respiratória em pacientes submetidos à colecistectomia laparoscópica. MATERIAIS E MÉTODOS: Em estudo prospectivo, 20 mulheres e 16 homens (idade: 48,4 ± 9,55 anos), submetidos à colecistectomia laparoscópica, foram divididos aleatoriamente: 17 realizaram exercícios respiratórios (respiração diafragmática, sustentação máxima da inspiração e inspiração fracionada) e 19 participaram como Grupo Controle. Todos realizaram avaliação das pressões respiratórias máximas (PImax e PEmax), pico de fluxo expiratório (PFE) e espirometria, medindo capacidade vital (CV), capacidade vital forçada (CVF), volume expiratório no primeiro segundo (VEF1), relação VEF1/CVF no pré-operatório e diariamente até o sexto pós-operatório (PO). RESULTADOS: Os valores de pré-operatório não foram estatisticamente diferentes entre os dois grupos. Ambos os grupos apresentaram diminuição de todas as variáveis no 1º PO (p< 0,05). O Grupo Exercício permaneceu com diminuição até o 2º PO para CV...

A colelitíase é uma doença frequente na população geral. Um dos seus fatores de risco é a diabetes melitus tipo 2, relacionada à anormalidades metabólicas associadas a sobrepeso, obesidade, resistência à insulina, hipertrigliceridemia e hábitos dietéticos. Fatores de risco semelhantes são encontrados na doença hepática gordurosa não alcoólica (DHGNA). A DHGNA engloba um espectro de condições patológicas que pode evoluir da esteatose, para esteato-hepatite (EHNA), fibrose, cirrose e neoplasia hepática. A distinção entre esteatose e EHNA é de grande relevância na prática clínica, em virtude de a primeira ser uma condição benigna e reversível, enquanto que a segunda apresenta potencial evolutivo para cirrose e carcinoma hepatocelular. Somente a biópsia hepática pode classificar e estadiar a DHGNA. A DHGNA e a colelitíase têm similaridade quanto à patogênese e aos fatores de risco, o que nos motivou a realizar este estudo. Os objetivos do trabalho foram: a) Definir a frequência da esteatose hepática e da EHNA em pacientes com colelitíase submetidos à colecistectomia laparoscópica. b) Avaliar as alterações histopatológicas da DHGNA nos pacientes com colelitíase. c) Avaliar a acurácia dos exames de imagem-ultrassonografia abdominal (US) e tomografia computadorizada (TC) no diagnóstico da DHGNA. d) Relacionar aspectos clínicos...

Introdução: A colelitíase é uma das afecções do sistema digestório mais frequente, acometendo 20% da população adulta. Atualmente, a colecistectomia videolaparoscópica (CVL) é o tratamento de escolha nas doenças benignas da vesícula biliar, inclusive, na colecistite aguda. Entretanto, independente dos benefícios indiscutíveis da cirurgia minimalmente invasiva, esse procedimento não exclui a possibilidade de complicações ou desconfortos ao paciente no pós-operatório. Objetivo: Identificar a relação entre as variáveis pré e intra-operatórias e as ocorrências de complicações e desconfortos pós-operatórios em pacientes submetidos à CVL. Casuística e método: Trata-se de um estudo retrospectivo, do tipo descritivo, exploratório, de nível I e com abordagem quantitativa. A amostra do estudo foi composta por 495 prontuários de pacientes submetidos à CVL, em caráter eletivo no Hospital Estadual de Diadema, no período entre janeiro de 2009 e agosto de 2012.

Background - Mechanical lifting of the abdominal wall, a method based on traction and consequent elevation of the abdominal wall, is an alternative procedure to create enough intra-abdominal space necessary for videolaparoscopic surgery, dispensing the need for intraperitoneal gas insufflation. Objective - This study aims to evaluate the technical feasibilility of this procedure to carry out a videolaparoscopic cholecystectomy, while analyzing the clinical and functional aspects of this technique. Patients and Methods - In the Digestive Tract Surgery Discipline of the Medical School at the University of São Paulo, São Paulo, SP, Brazil, was created the equipment to perform videolaparoscopic surgery using this method. The equipment has two sections: an external part which consisted of a frame attached to the operating table, inside which there is a sliding steel cable, moved by a ratched which is located at the lower end of one of the frame rods; the internal rod, the support, has an "L" shape, and its horizontal branch is made up of three turning rods and which is connected to the steel cable after insertion into the abdominal cavity. Ten patients underwent videolaparoscopic cholecystectomy using this equipment. The time taken to install the equipment...

Background: Pain is the primary complaint and the main reason for prolonged recovery after laparoscopic cholecystectomy. The authors hypothesized that patients undergoing laparoscopic cholecystectomy will have less pain four hours after surgery when receiving maintenance of anesthesia with propofol when compared to isoflurane, desflurane, or sevoflurane. Methods: In this prospective, randomized trial, 80 patients scheduled for laparoscopic cholecystectomy were assigned to propofol, isoflurane, desflurane, or sevoflurane for the maintenance of anesthesia. Our primary outcome was pain measured on the numeric analog scale four hours after surgery. We also recorded intraoperative use of opioids as well as analgesic consumption during the first 24 h after surgery. Results: There was no statistically significant difference in pain scores four hours after surgery (p = 0.72). There were also no statistically significant differences in pain scores between treatment groups during the 24 h after surgery (p = 0.45). Intraoperative use of fentanyl and morphine did not vary significantly among the groups (p = 0.21 and 0.24, respectively). There were no differences in total morphine and hydrocodone/APAP use during the first 24 h (p = 0.61 and 0.53...

The introduction and popularization of laparoscopic cholecystectomy has been accompanied with a considerable increase in perforation of gallbladder during this procedure (10%--32%), with the occurrence of intraperitoneal bile spillage and the consequent increase in the incidence of lost gallstones (0.2%--20%). Recently the complications associated with these stones have been documented in the literature. We report a rare complication occurring in an 81-year-old woman who underwent laparoscopic cholecystectomy and developed cutaneous fistula to the umbilicus and elimination of biliary stones through the urinary tract. During the cholecystectomy, the gall bladder was perforated, and bile and gallstones were spilled into the peritoneal cavity. Two months after the initial procedure there was exteriorization of fistula through the umbilicus, with intermittent elimination of biliary stones. After eleven months, acute urinary retention occurred due to biliary stones in the bladder, which were removed by cystoscopy. We conclude that efforts should be concentrated on avoiding the spillage of stones during the surgery, and that no rules exist for indicating a laparotomy simply to retrieve these lost gallstones.

BACKGROUND: Laparoscopic cholecystectomy has traditionally been performed with four incisions to insert four trocars, in a simple, efficient and safe way. AIM: To describe a simplified technique of laparoscopic cholecystectomy with two incisions, using basic conventional instrumental. TECHNIQUE: In one incision in the umbilicus are applied two trocars and in epigastrium one more. The use of two trocars on the same incision, working in "x" does not hinder the procedure and does not require special instruments. CONCLUSION: Simplified laparoscopic cholecystectomy with two incisions is feasible and easy to perform, allowing to operate with ergonomy and safety, with good cosmetic result.

BACKGROUND: Iatrogenic injury to the bile ducts is the most feared complication of cholecystectomy and several are the possibilities to occur. AIM: To compare the cases of iatrogenic lesions of the biliary tract occurring in conventional and laparoscopic cholecystectomy, assessing the likely causal factors, complications and postoperative follow-up. METHODS: Retrospective cohort study with analysis of records of patients undergoing conventional and laparoscopic cholecystectomy. All the patients were analyzed in two years. The only criterion for inclusion was to be operative bile duct injury, regardless of location or time of diagnosis. There were no exclusion criteria. Epidemiological data of patients, time of diagnosis of the lesion and its location were analyzed. RESULTS: Total of 515 patients with gallstones was operated, 320 (62.1 %) by laparotomy cholecystectomy and 195 by laparoscopic approach. The age of patients with bile duct injury ranged from 29-70 years. Among those who underwent laparotomy cholecystectomy...

BACKGROUND: In traditional laparoscopic cholecistectomy, the cystic duct and artery are commonly closed by metallic clips just before their division. Although the placement of these clips for occluding cystic artery and duct can be considered safe, biliary leaks and bleeding may occur especially by its dislodgement. AIM: To report a prospective case-series in total clipless cholecystectomy by means of harmonic shears for closure and division of the artery and cystic duct as well removal of the gallbladder from the liver. METHODS: Was evaluate a series of 125 patients who underwent laparoscopic cholecystectomy where the sealing and division of cystic artery and duct was carried out only by harmonic shears. The intact extracted gallbladder was submitted to a reverse pressure test for assessment of the technique safety by means of CO2 insuflation. RESULTS: The most common indication for surgery was gallstones. The mean operative time was 26 min and all gallbladders were dissected intact from the liver bed. There was no mortality and the overall morbidity rate was 0.8% with no hemorrhage or leaks. The reverse pressure test showed that all specimens support at least 36-mmHg of pressure without leaking. CONCLUSION: The harmonic shears is effective and safe in laparoscopic cholecystectomy as a sole instrument for sealing and division of the artery and cystic duct. The main advantages could be related to the safety and decreased operative time.

INTRODUCTION: Laparoscopic cholecystectomy is the gold standard for the treatment of gallstone disease; however, adverse hemodynamic changes induced by increased intraabdominal pressure due to pneumoperitoneum are known to occur. Herein, we investigated the effects of pneumoperitoneum on oxidative stress markers, including paraoxonase, arylesterase, total oxidant status, and total antioxidant status, during laparoscopic cholecystectomy. PATIENTS AND METHODS: Patients that underwent a laparoscopic cholecystectomy were classified as Group I, whereas patients that underwent surgical procedures for an abdominal wall hernia under general anesthesia were classified as Group II. Blood samples were obtained during the preoperative period, the perioperative period, and 24 hours after surgery (postoperative day 1). Leukocyte counts, neutrophil rates, paraoxonase activities, arylesterase activities, and total oxidant and antioxidant status levels were measured. RESULTS: The differences in leukocyte counts and neutrophil rates were not significant between the two groups. In Group I, no significant differences in the total oxidant and antioxidant status levels were identified; however, paraoxonase and arylesterase levels were lower on postoperative day 1. No significant changes were observed in the total oxidant status...

BACKGROUND: The present study evaluates the effect of laparoscopic cholecystectomy on biliary reflux in patients with cholelithiasis. METHODS: All patients over 18 years of age awaiting elective cholecystectomy for gallstone disease in one of two teaching hospitals were contacted by telephone, and those who gave informed consent were entered in the study. A total of 66 patients (43 females and 23 males) underwent milk 99mTc DIDA scans. Elective laparoscopic cholecystectomy was perfomed after a median of 28.5 days (range: 8-588 days) and patients were re-investigated with a milk 99mTc DIDA scan at a median time of 50 days (range: 18-370 days) postoperatively. Scans were carried out in the Nuclear Medicine Department of the Royal Adelaide Hospital. RESULTS: All but two patients had a functioning gall-bladder on milk 99mTc N-2, 6-dimethylphenyl-carbamoylmethyl iminodiacetic acid scanning prior to cholecystectomy. One of these patients was found to have a gall-bladder carcinoma at cholecystectomy. Fifty-seven of the 66 patients had a successful laparoscopic cholecystectomy (nine open cholecystectomies). Nineteen patients experienced gastroduodenal reflux into the stomach prior to cholecystectomy and 23 patients experienced it postoperatively. There was no significant difference in gastroduodenal reflux in both the open and laparoscopic groups. CONCLUSION: The present study demonstrated that laparoscopic cholecystectomy did not significantly alter gastroduodenal reflux.; Maddern...

Background: For day case laparoscopic cholecystectomy programmes, studies suggest that overnight admission may be predicted by the following factors: gall bladder wall thickness, patient age over 55 years and previous sphincterotomy. This study investigated the effect of relaxing selection for a day surgery laparoscopic cholecystectomy programme, by removing these factors from the exclusion criteria. Methods: Between September 2002 and April 2003, patients for elective laparoscopic cholecystectomy were considered for day surgery subject to standard criteria. For the initial part of the programme, patients were additionally excluded according to the risk factors mentioned above. Results: Thirty-three patients underwent intended day case procedures. The first 16 were selected according to the more rigorous criteria. The latter 17 were significantly older, with a significantly higher incidence of gall bladder wall thickening. There were seven admissions, three in the former part of the study and four in the latter. Conclusion: The exclusion criteria described are not necessary for a good same-day discharge rate; Matthew S. Metcalfe, Emma J. Mullin and Guy J.

Background: Laparoscopic cholecystectomy is now the gold standard procedure for symptomatic gallstone disease. Nevertheless, there are still several controversies such as the need for routine intraoperative cholangiogram (IOC), the indications for and results of early laparoscopic cholecystectomy in the setting of acute cholecystitis and the use of endoscopic retrograde cholangiopancreatography versus laparoscopic common bile duct (CBD) exploration for intraoperatively detected choledocholithiasis. The aim of this study was to investigate some of these controversies. Methods: All laparoscopic cholecystectomies carried out at our institution, a secondary referral centre in Adelaide, South Australia, over a 9-month period were prospectively audited. Data were collected regarding indications for surgery, rate of conversion to open operation, use of IOC, rate of choledocholithiasis and complication rate. Results: There were 202 patients, of whom 152 were women and 50 men. Age range was 15–83 years. Sixty-one per cent of emergency operations were for acute cholecystitis. The conversion rate for emergency operations was 20.6% and for elective procedures was 4.2% (P = 0.003).One hundred and eighty-four patients had an IOC performed. Twelve of these patients had choledocholithiasis. Six of these 12 patients had both normal preoperative ultrasound and liver function tests. Four of the patients went on to postoperative endoscopic retrograde cholangiopancreatography...

RESUMEN: El tratamiento de la colecistitis aguda contempla dos posibles alternativas quirúrgicas: colecistectomía temprana y colecistectomía diferida. La hipótesis de trabajo es que la colecistectomía temprana es segura en términos de morbi-mortalidad y puede aportar beneficios como menor estancia hospitalaria y menos reingresos. Se ha realizado un estudio retrospectivo comparando ambas opciones de tratamiento. Se analizan: el porcentaje de conversión, el tiempo quirúrgico, la morbilidad global, la morbilidad quirúrgica, la mortalidad, las reintervenciones, los días de estancia en cuidados intensivos, los reingresos hospitalarios, los días de ingreso hospitalario y los costes directos. En cirugía temprana se encuentra: menor morbilidad, a expensas de una menor tasa de infecciones y porcentajes de sangrado y lesión iatrogénica de la vía biliar similares, menor número de reingresos, menos estancias en cuidados intensivos y menos días de estancia hospitalaria. Además la cirugía temprana podría suponer un ahorro en costes directos.; ABSTRACT: Treatment of acute cholecystitis includes two possible surgical alternatives: early cholecystectomy and delayed cholecystectomy. The working hypothesis is that early cholecystectomy is safe in terms of morbidity and mortality and may provide benefits such as a shorter hospital stay and fewer readmissions.

PURPOSE: To evaluate and compare clinical and inflammatory responses to the surgical trauma caused by cholecystectomy via several access approaches: single-port umbilical incision (SILS), transvaginal natural orifice transluminal endoscopic surgery (NOTES), laparoscopy, and Laparotomy.METHODS: Twenty-eight female pigs were equally divided into four groups and submitted to cholecystectomy by single-port umbilical incision, transvaginal NOTES, laparoscopy, or Laparotomy. An additional five animals served as controls (sham group). Animals were monitored perioperatively regarding anesthesia and surgical procedure times, as well as for the presence of complications. Postoperatively, they were evaluated regarding time to ambulation and feeding, and the presence of clinical events. Procalcitonin, C-reactive protein (CRP), and AQUI feron-gamma (IFN-γ) measurements were performed before surgery and immediately, two days, and seven days after surgery. Animals were sacrificed and necropsied at seven days after surgery.RESULTS: All procedures were successfully performed as proposed in each group. Only minor complications, such as gallbladder perforation and bleeding from the liver bed, were observed during surgery in all groups. The vaginal NOTES group showed higher anesthesia and surgical procedure times compared to the other groups (p<0.001). No other between-group differences in perioperative or postoperative times...

PURPOSE: To observe the effect of cholecystectomy on the changes of motion pattern of Beagle dogs' sphincter of Oddi (SO), and investigate the modulatory role of nitric oxide (NO) and cholecystokinin (CCK) in the regulation of SO. METHODS: Pressure of common bile duct, SO motility, response to bolus injections of cholecystokinin (CCK, 20 ng/kg and 100 ng/kg), basal pressure (BP) and phasic contraction amplitude (PCA) were measured respectively by manometry in six Beagle dogs before and after cholecystectomy. RESULTS: After cholecystectomy, the pressure and diameter of common bile ducts (CBD) was significantly increased (p<0.01); BP and phasic contraction frequency (PCF) were also increased, however, no significant differences were found between the two groups; the SO motilities was not significantly changed. The relaxation responded to physiological dose of CCK (20ng/kg) was decreased, while bolus-dose of CCK (100ng/kg) induced rapid contractions and decreased PCA after cholecystectomy. The regulation pattern of SO pressure modulated by NO and its inhibitor had changed after cholecystectomy. CONCLUSION: After cholecystectomy in Beagle dogs, no obviously change of motion pattern of SO was observed through self-compensation...

OBJECTIVE: Laparoscopic cholecystectomy (LC) has become the gold standard for the surgical treatment of gallbladder disease, but conversion to open cholecystectomy is still inevitable in certain cases. Knowledge of the rate and impact of the underlying reasons for conversion could help surgeons during preoperative assessment and improve the informed consent of patients. We decided to review the rate and causes of conversion from laparoscopic to open cholecystectomy. METHOD: This study included all laparoscopic cholecystectomies due to gallstone disease undertaken from May 1999 to June 2010. The exclusion criteria were malignancy and/or existence of gallbladder polyps detected pathologically. Patient demographics, indications for cholecystectomy, concomitant diseases, and histories of previous abdominal surgery were collected. The rate of conversion to open cholecystectomy, the underlying reasons for conversion, and postoperative complications were also analyzed. RESULTS: Of 5382 patients for whom LC was attempted, 5164 were included this study. The overall rate of conversion to open cholecystectomy was 3.16% (163 patients). There were 84 male and 79 female patients; the mean age was 52.04 years (range: 26-85). The conversion rates in male and female patients were 5.6% and 2.2%...

Background: post-cholecystectomy bile duct injuries are identified by the onset of jaundice as well as elevated bilirubin and alkaline phosphatase levels during the peri-operative period. It is unknown how serum oxidative stress markers are modified in patients with post-cholecystectomy bile duct injuries. Objective: to determine serum oxidative stress marker levels (lipid peroxidation by-products, nitrites/nitrates and total antioxidant capacity) in patients with post-cholecystectomy bile duct injuries. Patients and methods: a prospective, transversal and analytical study was designed with two groups. Group 1: 5 healthy volunteer subjects. Group 2: 52 patients with post-cholecystectomy bile duct injuries (43 female and 9 male). An elective bilio-digestive reconstruction was performed at week 8. The serum oxidative stress marker levels were quantified by colorimetric method. Results: patients with bile duct injuries had a significant increased serum lipid peroxides (malondialdehyde and 4-hydroxy-alkenals) and nitric oxide metabolites (nitrites/nitrates) levels compared to the control group. In contrast, total antioxidant capacity in patients with bile duct injuries remained similar compared to healthy controls. Conclusions: the results show that oxidative stress is usually associated to bile duct injury.
