ABSTRACT
Background and study aims Significant weight regain affects up to one-third of patients after Roux-en-Y gastric bypass (RYGB) and demands treatment. Transoral outlet reduction (TORe) with argon plasma coagulation (APC) alone or APC plus full-thickness suturing TORe (APC-FTS) is effective in the short term. However, no study has investigated the course of gastrojejunostomy (GJ) or quality of life (QOL) data after the first post-procedure year. Patients and methods Patients eligible for a 36-month follow-up visit after TORe underwent upper gastrointestinal endoscopy with measurement of the GJ and answered QOL questionnaires (RAND-36). The primary aim was to evaluate the long-term outcomes of TORe, including weight loss, QOL, and GJ anastomosis (GJA) size. Comparisons between APC and APC-FTS TORe were a secondary aim. Results Among 39 eligible patients, 29 returned for the 3-year follow-up visit. There were no significant differences in demographics between APC and APC-FTS TORe groups. At 3 years, patients from both groups regained all the weight lost at 12 months, and the GJ diameter was similar to the pre-procedure assessment. As to QOL, most improvements seen at 12 months were lost at 3 years, returning to pre-procedure levels. Only the energy/fatigue domain improvement was kept between the 1- and 3-year visits. Conclusions Obesity is a chronic relapsing disease. Most effects of TORe are lost at 3 years, and redilation of the GJA occurs. Therefore, TORe should be considered iterative rather than a one-off procedure.
ABSTRACT
BACKGROUND AND AIMS: A significant number of patients regain weight after Roux-en-Y gastric bypass. Ablation with argon plasma coagulation (APC) plus endoscopic full-thickness suturing (FTS-APC) and ablation alone have been reported for treating weight regain when associated with gastrojejunostomy (GJ) dilation. However, comparative controlled data are still lacking. METHODS: This was a pilot single-center open-label randomized trial comparing the effectiveness and safety of APC alone versus FTS-APC for transoral outlet reduction. Patients with at least 20% weight regain from the nadir, and GJ ≥15 mm were considered eligible. The primary outcome was percentage total weight loss (%TWL) at 12 months. Secondary outcomes were the incidence of adverse events, amelioration of metabolic laboratory parameters, and improvement in quality of life and eating behavior. RESULTS: Forty patients meeting the eligibility criteria were enrolled from October 2017 to July 2018. Technical and clinical success rates were similar between the groups. At 12 months, the mean %TWL was 8.3% ± 5.5% in the APC alone group versus 7.5% ± 7.7% in the FTS-APC group (P = .71). The pre-revisional % solid gastric retention at 1 hour positively correlated with the probability of achieving ≥10% TWL at 12 months. Both groups experienced significant reductions in low-density lipoprotein and triglyceride levels at 12 months, and improvement in eating behavior and quality of life at 3 months. There were 2 cases of stenoses (1 from each group), which were successfully treated with endoscopic balloon dilation. CONCLUSION: APC alone is similar to FTS-APC in terms of technical and clinical outcomes within 1 year of follow-up. (Clinical trial registration number: NCT03094936.).

PURPOSE: Anemia due to iron deficiency or inflammatory state is often associated with obesity. Bariatric surgery is responsible for increasing iron deficiency, but weight loss decreases the inflammatory state associated with obesity. The objective of our study was to investigate the prevalence and causes of anemia before and after bariatric surgery for severe obesity in a 5-year follow-up. MATERIALS AND METHODS: Retrospective study, with electronic record analysis of obese patients, submitted to Roux-en-Y gastric bypass. Laboratory data were collected before and up to 60 months after surgery. Diagnosis and classification of anemia were done according to hemoglobin levels, serum ferritin, and transferrin saturation. RESULTS: Preoperatively, 8.8% of patients had anemia (93.2%, mild), and 43.8% of the patients had anemia due to chronic disease. After 24 months, there was a progressive increase of iron-deficiency anemia (72.4%) and decrease in anemia due to chronic disease (15.5%) and mixed (12.1%), with maintenance of this profile during long-term follow-up. CONCLUSION: Anemia is very frequent in severely obese patients and must be investigated both before and after bariatric surgery. The cause of anemia must be determined in order to use the best treatment available. We observed a reduction in the prevalence of chronic disease anemia during long-term follow-up probably due to the improvement in the systemic inflammatory state.

INTRODUCTION: Anatomical and functional influences on gastric bypass (GBP) results are often poorly evaluated and not yet fully understood. PURPOSE: The purpose of this study is to evaluate the influence of the gastric pouch volume and its emptying rate on long-term weight loss and food tolerance after GBP. MATERIALS AND METHODS: Weight loss, food tolerance, pouch volumetry (V) by three-dimensional reconstruction, and pouch emptying rate by 4 h scintigraphy were evaluated in 67 patients. Cutoffs were identified for V and retention percentage (%Ret) at 1 h (%Ret1). From these parameters, the sample was categorized, looking for associations between V, %Ret, weight loss, and food tolerance, assessed by a questionnaire for quick assessment of food tolerance (SS). RESULTS: PO median follow-up time was 47 months; median V was 28 mL; %Ret at 1, 2, and 4 h were 8, 2, and 1%, respectively. There were associations between V ≤ 40 mL and higher emptying rates up to 2 h (V ≤ 40 mL: %Ret1 = 6, %Ret2 = 2, p = 0.009; V > 40 mL: %Ret1 = 44, %Ret2 = 13.5, p = 0.045). An association was found between higher emptying speed in 1 h and higher late weight loss (WL), represented by lower percentage of excess weight loss (%EWL) regain (p = 0.036) and higher %EWL (p = 0.033) in the group with %Ret1 ≤ 12%, compared to the group %Ret1 ≥ 25%. Better food tolerance (SS > 24), was associated with lower %Ret1 (p = 0.003). CONCLUSION: Smaller pouch size is associated with a faster gastric emptying, greater WL maintenance, and better food tolerance. These data suggest that a small pouch with rapid emptying rate is an important technical parameter for good outcomes in GBP.

BACKGROUND: The Roux-en-Y gastric bypass (RYGB) is the gold standard bariatric operation. However, a major concern in late follow-up is the substantial weight regain. Understanding the role of gastrointestinal hormone secretion in this situation is relevant. METHODS: The aim of the present study was to evaluate the influence of gastrointestinal hormones comparing postprandial secretion of ghrelin, glucose-dependent insulinotropic polypeptide (GIP), glucagon-like peptide 1 (GLP-1), and leptin between patients with weight regain and those with favorable weight control. Twenty-four patients with follow-up from 27 to 59 months were divided into two groups according to sustained weight loss: group A (14 patients) had sustained weight losses, and group B (10 patients) had significant weight regain. Basal serum levels of ghrelin, GIP, GLP-1, and leptin after fasting and 30, 60, 90, and 120 min after a standard meal were measured. RESULTS: There was no difference in the ghrelin secretion. There was a difference in the GIP secretion, with a higher percentage increase in 30 min in group A (330% × 192.2%; p = 0.01). There were also differences in the GLP-1 secretion, with higher increases in absolute (p = 0.03) and percentage values after 30 min in group A (124% × 46.5%; p = 0.01). There was also a difference between baseline leptin values, with higher levels in group B (p = 0.02). CONCLUSIONS: The secretion of gut hormones in patients with weight regain after RYGB is different from that in patients with satisfactory weight outcome. After meal stimulation, reduced levels of GIP and GLP-1 may indicate the influence of gut hormones in the process of weight regain.

BACKGROUND: Surgical treatment of obesity in the elderly, particularly over 65, remains controversial; it is explained by the increased surgical risk or the lack of data demonstrating its long-term benefit. Few studies have evaluated the clinical effects of bariatric surgery in this population. AIM: To evaluate the results of surgical treatment of obesity in patients over 60 years, followed for an average period of five years. METHOD: This was a retrospective study evaluating 46 patients, 60 years or older, who underwent surgical treatment of obesity, by conventional gastric bypass technique (laparotomy). The average age was 64 years (60-71), mean BMI of 49.6 kg/m2 (38-66), mean follow-up of 5.9 years; 91% of patients were hypertensive, 56% diabetics and 39% had dyslipidemia. RESULTS: The incidence of complications (major and minor) in patients under 65 years was 26% and over 65 years 37% (p=0.002). There were no deaths in the group with less than 65 years and there were two deaths (12.5%) over 65 years. The average loss of overweight over 65 years or less was 72% vs 68% (p=0.56). There was total control of the diabetes mellitus in 77% and partial in 23%, with no difference between groups. There was improvement in arterial hypertension in 56% of patients, also no difference between groups. The average LDL levels did not differ between the pre and postoperative (106 mg/dl to 102 mg/dl), an increase of HDL (56 mg/dl to 68 mg/dL) and reduced triglyceride levels (136 mg/dl to 109 mg/dl). There was no statistical difference in the variation of the cholesterol fractions and triglycerides between the groups. Two patients in the group with less than 65 years died in late follow-up, of brain tumor and pneumonia, three and five years after bariatric surgery, respectively. CONCLUSIONS: Surgical morbidity and mortality were higher in patients over 65 years, and this group had the same benefits observed in patients lower 65 years for weight loss and comorbidities control.

Racional: O tratamento cirúrgico da obesidade em idosos, em particular nos indivíduos com mais de 65 anos, permanece controverso; seja pelo risco cirúrgico aumentado ou pela ausência de dados que demonstrem seu benefício em longo prazo.Objetivo: Avaliar os resultados do tratamento cirúrgico em pacientes com mais de 60 anos, seguidos por um período médio de cinco anos. Método: Estudo retrospectivo que avaliou 46 pacientes com 60 anos ou mais, submetidos ao bypass gástrico convencional (laparotomia). A idade média foi de 64 anos (60-71), IMC médio de 49,6 kg/m2 (38-66), tempo médio de seguimento de 5,9 anos. Pacientes eram hipertensos eram 91%, diabéticos 56% e 39% tinham dislipidemia.Resultados: A incidência de complicações (maiores e menores) nos com menos de 65 anos foi de 26% e com mais de 65 anos de 37% (p=0,002). Não houve óbitos no grupo com menos de 65 anos e houve dois óbitos (12,5%) no com mais de 65. A perda média de excesso de peso nos pacientes com mais ou menos de 65 anos foi de 72% x 68% (p=0,56). Houve controle total do diabete melito em 77% dos pacientes e parcial em 23%, sem diferença entre os grupos com mais ou menos de 65 anos. Houve melhora da hipertensão arterial em 56% dos pacientes também sem diferença entre os grupos. Os níveis médios de LDL não variaram entre o pré e pós-operatório (106 mg/dl para 102 mg/dl), houve aumento do HDL (56 mg/dl para 68 mg/dl) e redução do triglicérides (136 mg/dl para 109 mg/dl). Não houve diferença estatística na variação das frações de colesterol e triglicerídeos entre os grupos. Dois pacientes do grupo com menos de 65 anos morreram no seguimento tardio por tumor cerebral e pneumonia, três e cinco anos após a cirurgia bariátrica, respectivamente. Conclusões: A morbimortalidade cirúrgica nos pacientes com mais de 65 anos foi maior. Mas, os acima de 65 tiveram os mesmos benefícios observados nos com menos de 65 anos, em relação à perda de peso e controle de comorbidades.

CONTEXT: Bariatric surgery has become the most effective method for producing weight loss in obese patients. The evaluation of improvement of comorbidities and changes in the quality of life are important outcome factors; however, it is necessary to investigate whether they persist over the long term. METHODS: A cross-sectional study was conducted on 143 obese patients from our institution from February 2007 to February 2008. These patients were divided into five independent groups, one being a control group, plus four other groups with 1, 2, 3, 4 or more years following surgical Roux-en-Y gastric bypass with a silicon ring banded. quality of life forms and anthropometric measurements were performed and its scores correlated with social factors, weight loss success, and status of obesity-related conditions. RESULTS: For the group that was 1 year postoperative, a significant percentage of excess body weight loss (EBWL%) of 81.7% was observed. The groups with 2, 3, 4 or more years of post-surgical follow-up showed a EBWL decline, but without significant difference. The main comorbidity percentages in all patients who had the surgery was as follows: 69.7% for hypertension; 88.2% for diabetes mellitus; and 27.5% for arthropathy. There was a significant decrease in the rate for diabetes resolution (P = 0.035) observed by evolutionary assessment of the comorbidity resolution. The results obtained by BAROS were good, very good, or excellent in more than 96% of patients in all evaluations that were performed. The use of the Moorehead-Ardelt Questionnaire (M/A) demonstrated improvement in the quality of life. Moreover, the quality of life, when evaluated through SF-36, also showed improvement in all related areas after 1 year; however, after 4 years, improvement remained elevated only in the areas of general state of health and functional capacity. CONCLUSIONS: The Roux-en-Y gastric bypass procedure was able to achieve EBWL of 81.7% after 1 year following surgery, remaining steady with little decline after this period. Important resolution of comorbidities, such as hypertension and diabetes, was also seen. Immediate surgical outcomes assessed by SF-36 and M/A in the area of quality of life were satisfactory, but the general state of health and functional capacity areas were sustained satisfactory at a later time only.

Contexto A cirurgia bariátrica tem se sedimentado como o método mais eficaz de tratamento da obesidade mórbida. A avaliação da melhora de comorbidades e efeitos na qualidade de vida e, a manutenção destas alterações a longo prazo, são fatores com importantes influências no resultado do tratamento cirúrgico. Métodos Estudo transversal foi realizado em 143 pacientes obesos da nossa instituição, entre fevereiro de 2007 a fevereiro de 2008. Estes pacientes foram divididos em cinco grupos independentes, sendo um deles o grupo de controle, além de outros quatro grupos com 1, 2, 3, e 4 ou mais anos de seguimento cirúrgico após gastroplastia em Y de Roux com uso de bandagem com anel de silicone. Avaliação da qualidade de vida e medidas antropométricas foram realizadas, e seus escores correlacionados com fatores sociais, perda de peso, e status de condições relacionadas com a obesidade. Resultados Para o grupo de 1 ano de pós- operatório, uma porcentagem significativa de perda de excesso de peso corporal, 81,7%, foi observada. Os grupos com 2, 3, e 4 ou mais anos de pós-operatório em acompanhamento mostraram um declínio da perda de excesso de peso, mas sem diferenças significativas.

CONTEXT: Obesity in the elderly is associated with exacerbation of functional decline (dependency), that occurs with aging, because of decreased muscle mass and strength, and increased joint dysfunction. Consequently, there is progressive loss of independence, autonomy, chronic pain and impaired quality of life. The weight loss can bring benefits in all these aspects, especially when accompanied by exercises. Elderly patients with morbid obesity may be submitted to surgical treatment, taking into account that the massive weight loss, eventually caused by bariatric surgery, may exacerbate the loss of muscle mass and nutritional complications that may bring harm to the overall health and quality of life of these patients. The functional assessment of elderly patients, candidates for bariatric surgery and the extent to which surgery can bring benefits to the patients, in the field of functionality, has still to be determined. OBJECTIVE: To describe profile functionality in obese elderly referred to a bariatric surgery program. METHODS: Patients with age ≥ 60 and BMI ≥ 35 underwent comprehensive geriatric assessment that evaluates co morbidities, medication use, ability to perform basic activities of daily living and instrumental activities of daily living, and the "Timedupandgo" test to evaluate mobility, whose cut-off point was ≤ 10 seconds. Statistical analysis was performed in order to see if there is a positive correlation of dependency with BMI and age (over or under 65 years). Results Forty subjects have completed evaluation. The mean age was 64.1 years (60-72) and 75% were women. They had an average weight of 121.1 kg (72.7-204) and a mean BMI of 47.2 kg/m2 (35.8-68.9). 16 patients (40%) have shown dependency for activities of daily living, 19 (47,5%) for instrumental activities of daily living and 20 patients (50%) had a "Timedupandgo" test over 10 seconds. Statistical analysis (t-Student, Mann-Whitney, Binary Logistic Regression) has shown positive correlation of dependency in activities of daily living for BMI >49 kg/m2, dependency in instrumental activities of daily living for BMI >46,5 kg/m2, and "Timedupandgo" test greater than 10 seconds for BMI >51 kg/m2 (P<0,05). No dependency difference was observed for patients over or under 65 years age. CONCLUSIONS: Functional decline is observed in almost half of the morbid obese patients over 60 years old. It is related to increasing BMI (BMI >46,5 kg/m2) but not related to age (60 to 65 years or over 65 years). Functional decline should be considered a co-morbidity in the elderly obese patients and should be assessed before bariatric surgery in this population.

Contexto A obesidade em idosos está associada ao maior comprometimento da funcionalidade, que ocorre com o envelhecimento e em decorrência de perda de massa e força muscular, além de disfunção articular. Como consequência, há perda progressiva de autonomia, dor crônica, diminuição de qualidade de vida e dependência progressiva. A perda de peso pode trazer benefícios em todos esses aspectos, principalmente quando acompanhada de exercícios físicos. Pacientes idosos com obesidade mórbida podem ser submetidos ao tratamento cirúrgico, levando-se em consideração que a perda de peso maciça, proporcionada pela cirurgia bariátrica, pode agravar a perda de massa muscular e trazer complicações nutricionais que poderão prejudicar a saúde global e a qualidade de vida desses pacientes. A avaliação funcional de pacientes idosos candidatos à cirurgia bariátrica e, em que medida a cirurgia pode trazer benefícios ao paciente no campo da funcionalidade ainda precisam ser determinadas. Objetivos Objetivo - O objetivo deste estudo foi avaliar o perfil de funcionalidade de pacientes idosos em um programa de cirurgia bariátrica. Método Trata-se de um estudo transversal que avaliou por meio de entrevista, exame físico, exames laboratoriais e revisão de prontuários pacientes com obesidade graus II e III, candidatos à cirurgia bariátrica, com 60 anos ou mais. A análise incluiu peso, IMC, presença de comorbidades mais comuns, utilização de medicações para doenças crônicas e testes funcionais. Para os últimos foram utilizados questionários de avaliação de atividades diárias, atividades diárias instrumentalizadas e o teste “Timeupandgo” que avalia mobilidade, cujo tempo de corte é de até ...

OBJECTIVES: The incidence of obesity and particularly super obesity, has increased tremendously. At our institution, super obesity represents 30.1% of all severely obese individuals in the bariatric surgery program. In super obesity, surgical morbidity is higher and the results are worse compared with morbid obesity, independent of the surgical technique. The primary strategy for minimizing complications in these patients is to decrease the body mass index before surgery. Preoperative weight reduction can be achieved by a hypocaloric diet, drug therapy, an intragastric balloon, or hospitalization. The objective of this study was to analyze the results of a period of hospitalization for preoperative weight loss in a group of super-obese patients. METHODS: Twenty super-obese patients were submitted to a weight loss program between 2006 and 2010. The mean patient age was 46 years (range 21-59). The mean BMI was 66 kg/m2 (range 51-98) and 12 were women. The average hospital stay was 19.9 weeks and the average weight loss was 19% of the initial weight (7-37%). The average caloric intake was 5 kcal/kg/day. After the weight loss program, the patients underwent gastric bypass surgery. RESULTS: The statistical analysis revealed that after 14 weeks of treatment (15% loss of initial weight), the weight loss was not significant. All patients had satisfactory surgical recovery and were discharged after an average of 4.6 days. CONCLUSION: In super obesity, preoperative weight loss is an important method for reducing surgical risks. Hospitalization and a hypocaloric diet are safe and effective. After 14 weeks, the weight loss rate stabilized, signaling the time of surgical intervention in our study.

CONTEXT: Bariatric surgery has proven to be the most effective method of treating severe obesity. Nevertheless, the acceptance of bariatric surgery is still questioned. The surgical complications observed in the early postoperative period following surgeries performed to treat severe obesity are similar to those associated with other major surgeries of the gastrointestinal tract. However, given the more frequent occurrence of medical comorbidities, these patients require special attention in the early postoperative follow-up. Early diagnosis and appropriate treatment of these complications are directly associated with a greater probability of control. METHOD: The medical records of 538 morbidly obese patients who underwent surgical treatment (Roux-en-Y gastric bypass surgery) were reviewed. Ninety-three (17.2%) patients were male and 445 (82.8%) were female. The ages of the patients ranged from 18 to 70 years (average = 46), and their body mass indices ranged from 34.6 to 77 kg/m2. RESULTS: Early complications occurred in 9.6% and were distributed as follows: 2.6% presented bleeding, intestinal obstruction occurred in 1.1%, peritoneal infections occurred in 3.2%, and 2.2% developed abdominal wall infections that required hospitalization. Three (0.5%) patients experienced pulmonary thromboembolism. The mortality rate was 0,55%. CONCLUSION: The incidence of early complications was low. The diagnosis of these complications was mostly clinical, based on the presence of signs and symptoms. The value of the clinical signs and early treatment, specially in cases of sepsis, were essential to the favorable surgical outcome. The mortality was mainly related to thromboembolism and advanced age, over 65 years.

Context Bariatric surgery has proven to be the most effective method of treating severe obesity. Nevertheless, the acceptance of bariatric surgery is still questioned. The surgical complications observed in the early postoperative period following surgeries performed to treat severe obesity are similar to those associated with other major surgeries of the gastrointestinal tract. However, given the more frequent occurrence of medical comorbidities, these patients require special attention in the early postoperative follow-up. Early diagnosis and appropriate treatment of these complications are directly associated with a greater probability of control. Method The medical records of 538 morbidly obese patients who underwent surgical treatment (Roux-en-Y gastric bypass surgery) were reviewed. Ninety-three (17.2%) patients were male and 445 (82.8%) were female. The ages of the patients ranged from 18 to 70 years (average = 46), and their body mass indices ranged from 34.6 to 77 kg/m2. Results Early complications occurred in 9.6% and were distributed as follows: 2.6% presented bleeding, intestinal obstruction occurred in 1.1%, peritoneal infections occurred in 3.2%, and 2.2% developed abdominal wall infections that required hospitalization. Three (0.5%) patients experienced pulmonary thromboembolism. The mortality rate was 0,55%. Conclusion The incidence of early complications was low.

Contexto A cirurgia bariátrica tem mostrado ser o método mais eficaz de tratamento da obesidade grave. No entanto, sua aceitação como terapia padrão-ouro ainda é questionada. As complicações cirúrgicas observadas no início do período pós-operatório de cirurgias para o tratamento da obesidade grave são semelhantes aos associados a outras cirurgias de grande porte do trato gastrointestinal. Não obstante, dada a ocorrência mais frequente de comorbidades associadas à obesidade mórbida, esses pacientes necessitam de atenção especial no pós-operatório. O diagnóstico precoce e o tratamento adequado dessas complicações estão diretamente associadas a maior probabilidade de controle clínico. Método Os prontuários de 538 pacientes obesos mórbidos submetidos a tratamento cirúrgico (bypass gástrico em Y-de-Roux) foram revisados. Noventa e três (17,2%) pacientes eram do sexo masculino e 445 (82,8%) eram do sexo feminino. As idades dos pacientes variaram de 18 a 70 anos (média = 46) e seus índices de massa corporal variaram entre 34,6-77 kg/m2. Resultados As complicações imediatas ocorreram em 9,6% e foram distribuídos da seguinte forma: 2,6% apresentaram sangramento, obstrução intestinal ocorreu em 1.1%, infecções peritoniais ocorreram em 3,2% e 2,2% desenvolveram infecções da parede abdominal requerendo hospitalização. Três (0,5%) pacientes tiveram tromboembolismo pulmonar. Conclusão A padronização de cirurgia para o tratamento da obesidade mórbida tem contribuído significativamente para os baixos índices de complicações e mortalidade. A incidência de complicações precoces foi baixa. O ...

CONTEXT: About 9% of the Brazilian population has gallstones and the incidence increases significantly with aging. The choledocholithiasis is found around 15% of these patients, and a third to half of these cases presented as asymptomatic. Once the lithiasis in the common bile duct is characterized through intraoperative cholangiography, the laparoscopic surgical exploration can be done through the transcystic way or directly through choledochotomy. OBJECTIVE: To evaluate the results and outcomes of the laparoscopic treatment of common bile duct lithiasis. METHODS: Seventy consecutive patients were evaluated. They prospectively underwent the treatment of the lithiasis in the common bile duct and the exploration ways were compared according to the following parameters: criteria on their indication, success in the clearance, surgical complications. It was verified that about ½ of the choledocholithiasis carriers did not show any expression of predictive factors (clinical antecedents of jaundice and/or acute pancreatitis, compatible sonographic data and the pertaining lab tests). The laparoscopic exploration through the transcystic way is favored when there are no criteria for the practice of primary choledochotomy, which are: lithiasis in the proximal bile duct, large (over 8 mm) or numerous calculi (multiple calculosis). RESULTS: The transcystic way was employed in about 50% of the casuistic and the choledochotomy in about 30%. A high success rate (around 80%) was achieved in the clearance of the common bile duct stones through laparoscopic exploration. The transcystic way, performed without fluoroscopy or choledochoscopy, attained a low rate of success (around 45%), being 10% of those by transpapilar pushing of calculi less than 3 mm. The exploration through choledochotomy, either primary or secondary, if the latter was performed after the transcystic route failure, showed high success rate (around 95%). When the indication to choledochotomy was primary, the necessity for choledochoscopy through choledochotomy to help in the removal of the calculi was 55%. However, when choledochotomy was performed secondarily, in situations where the common bile duct diameter was larger than 6 mm, the use of choledochoscopy with the same purpose involved about 20% of the cases. There was no mortality in this series. CONCLUSION: The laparoscopic exploration of the common bile duct was related to a low rate of morbidity. Therefore, the use of laparoscopy for the treatment of the lithiasis in the common bile duct depends on the criteria for the choice of the best access, making it a safe procedure with very good results.

CONTEXTO: Aproximadamente 9% da população brasileira apresenta colecistolitíase e esta incidência aumenta significativamente com o envelhecimento. A coledocolitíase é encontrada em torno de 15% destes pacientes, e de um terço a metade destes casos apresenta-se de maneira assintomática. Uma vez que a litíase do ducto biliar comum é caracterizada através de colangiografia intra-operatória, a exploração cirúrgica laparoscópica pode ser feita através da via transcística, ou diretamente através de coledocotomia. OBJETIVO: Avaliar os resultados do tratamento laparoscópico da coledocolitíase. MÉTODOS: Setenta pacientes foram avaliados prospectivamente. Todos foram submetidos ao tratamento da coledocolitíase por videolaparoscopia, e as formas de exploração foram comparadas de acordo com os seguintes parâmetros: os critérios de sua indicação, o sucesso no clareamento da via biliar, complicações cirúrgicas. A exploração laparoscópica transcística foi favorecida quando não há critérios para a prática de coledocotomia primária, sendo estes litíase do ducto biliar proximal, cálculos grandes (mais de 8 mm) ou calculose múltipla. RESULTADOS: Verificou-se que cerca de um terço dos doentes com coledocolitíase não mostraram qualquer expressão de fatores preditivos (antecedentes clínicos de icterícia e/ou pancreatite aguda, suspeita ultrassonográfica ou alterações de testes laboratoriais relacionados à coledocolitíase). A exploração transcística foi empregada em cerca de 50% dos casos e a coledocotomia em cerca de 30%. A depuração da via biliar através da laparoscopia foi alcançada em 80% dos casos. A exploração transcística, realizada sem fluoroscopia ou coledocoscopia, atingiu baixa taxa de sucesso (em torno de 45%), sendo 10% desses casos com passagem transpapilar de cálculos com menos de 3 mm. A exploração por coledocotomia, primária ou secundária, quando esta foi realizada após o insucesso da via transcística, mostrou alta taxa de sucesso (em torno de 95%). Quando a indicação para coledocotomia era primária, a necessidade de visualização direta através da coledocoscopia para ajudar na remoção dos cálculos foi de 55%. No entanto, quando foi realizada coledocotomia secundariamente, nas situações em que o diâmetro do ducto biliar comum foi maior do que 6 mm, o uso de coledocoscópio com o mesmo propósito foi necessário em cerca de 20% dos casos. Não houve mortalidade nesta série. CONCLUSÃO: A exploração laparoscópica da via biliar principal está relacionada com baixa taxa de morbidade. Portanto, o uso da laparoscopia para o tratamento da coledocolitíase depende dos critérios para a escolha do melhor acesso, tornando-se procedimento seguro, com resultados bastante satisfatórios.
