Impact of Intra-Operative Fluid Therapy on Short Term Outcomes in Patients Undergoing Advanced Laparoscopic Colorectal Operations Performed for Colorectal Cancer.

BACKGROUND There has been a recent shift in the operative approach in advanced colorectal operations where in laparoscopy is being used as the preferred modality of intra-abdominal access. Literature is not clear and there is no consensus with regards to the optimal intraoperative fluid requirements in these operations. Hence, we did a retrospective study of intraoperative fluid requirements for all laparoscopic advanced colorectal resection operations and looked at its impact on short term postoperative recovery.METHODSThis is a retrospective analysis of all patients who have undergone advanced laparoscopic colorectal resections in colorectal surgical unit in a single tertiary care centre in south India from January 2014 to June 2017. Data was collected from prospectively maintained electronic inpatient and outpatient charts. The outcomes analysed were postoperative morbidity and length of postoperative hospital stay with respect to intra-operative rate of intravenous (IV) fluid administration.RESULTSThere was a total of 201 laparoscopic advanced colorectal resections performed from January 2014 to June 2017. The median IV fluid rate was 5.2 ml/Kg/hr (SD-1.97). Seventy nine of 201 patients were documented to have morbidity based on Clavien-Dindo classification. Patients who received intraoperative IV fluids </= 5 ml/Kg/hr were categorised into the restrictive fluid regimen group and patients who received > 5 ml/Kg/hr were categorised into the liberal fluid regimen group. Out of the 79 patients with post-operative morbidity, there was a statistically significant difference between the restrictive fluid group 32/79 (40.5%) and the liberal fluid group 47/79 (59.5%) with a p value of 0.03.CONCLUSIONSIntra-operative liberal fluid management seems to be associated with increased postoperative morbidity in laparoscopic advanced colorectal resections.

Morbidity After cardiac surgery under cardiopulmonary bypass and associated factors: A retrospective observational study

Background The present study aimed to assess the morbidity after cardiac surgery and identify the preoperative and intraoperative factors associated with postoperative morbidity. Methods A retrospective observational study was conducted including 362 adult patients aged 18–75 years who underwent open-heart surgery under cardiopulmonary bypass at Sri Jayadeva Institute of Cardiovascular Sciences and Research, Bengaluru, India, during the period from June 2016 to May 2017. Using a structured schedule, preoperative and intraoperative data were collected from the hospital's cardiac surgery database, whereas the postoperative data were collected from the intensive care unit (ICU) database and the hospital's clinical information system database. Results Of 362 patients, 254 (70.2%) had at least one major complication, and the most frequently occurring complication was low cardiac output state (29.8%). The ICU length of stay (LOS) was for > 2 days in 23.2% of patients, and the hospital LOS was for > 7 days in almost 60% of the patients. Multivariate logistic regression analyses revealed that gender, type of surgery, body weight, blood lactate level at ICU admission, and 12-h blood lactate level were significant predictors of complications; gender and 24-h blood lactate level were significantly associated with the prolonged ICU LOS, whereas type of surgery and 24-h blood lactate level were significantly associated with prolonged hospital LOS. Conclusion The appropriate patient management strategy can be tailored based on the personal attributes, surgery type, and blood lactate level for individual patients undergoing cardiac surgery to reduce the likelihood of postoperative complications, ICU LOS, and hospital LOS.

A Modified Surgical Approach of Hepatopancreatoduodenectomy for Advanced Gallbladder Cancer: Report of Two Cases and Literature Review / 华中科技大学学报（医学）（英德文版）

Gallbladder cancer (GBC) is the most common cancer of the biliary tract,constituting 80％-95％ of malignant biliary tract tumors.Surgical resection is currently regarded as the sole curative treatment for GBC.Hepatopancreatoduodenectomy (HPD) has been adopted to remove the advanced gallbladder tumor together with the infiltrated parts within the liver,lower biliary tract and the peripancreatic region of GBC patients.However,patients who underwent HPD were reported to have a distinctly higher postoperative morbidity (71.4％,ranging from 30.8％ to 100％) and mortality (13.2％,ranging from 2.4％ to 46.9％) than those given pancreatoduodenectomy (PD) alone.We present two patients with advanced GBC who underwent a modified surgical approach ofHPD:PD with microwave ablation (MWA) of adjacent liver tissues and the technique of intraductal cooling of major bile ducts.No serious complications like bile leakage,pancreatic fistula,hemorrhage and organ dysfunction,etc.occurred in the two patients.They had a rapid recovery with postoperative hospital stay being 14 days.Application of this approach effectively eliminated tumor-infiltrated adjacent tissues,and maximally reduced the postoperative morbidity and mortality.This modified surgical method is secure and efficacious for the treatment of locally advanced GBC.

Incidental splenic injury and splenectomy: an overview based on available evidence / Lesión esplénica incidental y esplenectomía: una visión general basada en la evidencia disponible

Splenectomy indications are hematologic disease, traumatic damage and iatrogenic injury. The aim of this study was to present an evidence-based overview of some clinical aspects of interest related with iatrogenic splenic injury and subsequent splenectomy. An overview of the available evidence was conducted. Articles that evaluated clinical aspects of interest related with iatrogenic splenic injury and subsequent splenectomy, without language limits, publication date and designs. BVS, PubMed, SciELO and TRIP databases were reviewed. Evaluated variables were: Frequency and etiology of surgical spleen injuries, treatment options, frequency of splenectomy, associated postoperative morbidity (POM) and mortality, recommendation for splenectomy. Classification of the available evidence was made using the classification proposed by Oxford Centre of Evidence-based Medicine. 1144 records were obtained. 1109 were discarded for not meeting eligibility criteria, or were not relevant for the purpose of this research. Finally, the study consisted of 35 articles, 3 of evidence level type 3a, 31 of evidence level type 4 and 1 of evidence level type 5. Splenectomy is a complication of common abdominal procedures, prevalence and incidence of iatrogenic splenic injury is underestimated because of lack of information, there is evidence of risk factors of surgical spleen injuries, the etiology of surgical spleen injuries are bariatric, esophago-gastric, antireflux, colorectal, abdominal vascular and urological procedures. POM in patients undergoing splenectomy is more frequent in emergency splenectomy secondary to trauma. There was no significant risk reduction of infectious complications after implementation of routine vaccination. Available evidence is based on few and heterogeneous articles, which make a meaningful conclusions difficult. Studies with better evidence levels, methodological quality and population size are needed for conclusions and recommendations.

Las indicaciones de esplenectomía son enfermedades hematológicas, daño por trauma y por lesiones iatrogénicas. El objetivo de este estudio es presentar una visión general basada en la evidencia actualmente disponible, respecto de algunos aspectos clínicos de interés relacionados con la lesión esplénica iatrogénica y posterior esplenectomía. Revisión global de la evidencia disponible. Se incluyeron artículos que evaluaron aspectos clínicos de interés relacionados con lesión esplénica iatrogénica y posterior esplenectomía; sin límites de lenguaje, fecha de publicación y diseño. Se revisaron las bases de datos BVS, PubMed, SciELO y Trip Database. Las variables evaluadas fueron: frecuencia y etiología de las lesiones, opciones de tratamiento, frecuencia de esplenectomía, morbimortalidad postoperatoria, recomendación de esplenectomía. La clasificación de la evidencia se realizó con la propuesta del Centro de Medicina Basada en la Evidencia de Oxford. Se obtuvieron 1144 registros. 1109 fueron descartados por no cumplir criterios de elegibilidad, o ser no relevantes para el objetivo de la investigación. La población en estudio quedó compuesta por 35 artículos, 3 de nivel de evidencia 3a, 31 de nivel de evidencia 4 y 1 de nivel de evidencia 5. La esplenectomía es una complicación propia de la cirugía abdominal. La prevalencia e incidencia de lesión esplénica iatrogénica es subestimada por falta de información. Hay evidencia de factores de riesgo de lesiones del bazo. La etiología de estas es: procedimientos bariátricos, esófago-gástricos, colorrectales, vasculares abdominales y urológicos. La morbilidad es más frecuente en esplenectomía de emergencia secundaria a trauma. No se ha registrado disminución significativa del riesgo de complicaciones infecciosas con la vacunación rutinaria. La evidencia disponible se basa en pocos artículos y heterogéneos, lo que impide sacar conclusiones. Se necesitan estudios de mejor nivel de evidencia, calidad metodológica y tamaño de muestra para obtener conclusiones válidas y recomendaciones adecuadas.

Hyperlactatemia in patients undergoing adult cardiac surgery under cardiopulmonary bypass: Causative factors and its effect on surgical outcome.

Objectives of the Study: To identify the factors causing high lactate levels in patients undergoing cardiac surgery under cardiopulmonary bypass (CPB) and to assess the association between high blood lactate levels and postoperative morbidity and mortality. Methods: A retrospective observational study including 370 patients who underwent cardiac surgeries under cardiopulmonary bypass. The patients were divided into 2 groups based on serum lactate levels; those with serum lactate levels greater than or equal to 4 mmol/L considered as hyperlactatemia and those with serum lactate levels less than 4 mmol/L. Blood lactate samples were collected intraoperatively and postoperatively in the ICU. Preoperative and intraoperative risk factors for hyperlactatemia were identified using the highest intraoperative value of lactate. The postoperative morbidity and mortality associated with hyperlactatemia was studied using the overall (intraoperative and postoperative values) peak lactate levels. Preoperative clinical data, perioperative events and postoperative morbidity and mortality were recorded. Results: Intraoperative peak blood lactate levels of 4.0 mmol/L or more were present in 158 patients (42.7%). Females had higher peak intra operative lactate levels (P = 0.011). There was significant correlation between CPB time (Pearson correlation coefficient r = 0.024; P = 0.003) and aortic cross clamp time (r = 0.02, P = 0.007) with peak intraoperative blood lactate levels. Patients with hyperlactatemia had significantly higher rate of postoperative morbidity like atrial fibrillation (19.9% vs. 5.3%; P = 0.004), prolonged requirement of inotropes (34% vs. 11.8%; P = 0.001), longer stay in the ICU (P = 0.013) and hospital (P = 0.001). Conclusions: Hyperlactatemia had significant association with post-operative morbidity. Detection of hyperlactatemia in the perioperative period should be considered as an indicator of inadequate tissue oxygen delivery and must be aggressively corrected.

Determinants of prolonged length of hospital stay after cardiac surgery: impact of rheumatic heart disease / Determinantes de internação hospitalar prolongada após cirurgia cardíaca: impacto de cardiopatia reumática

BACKGROUND: Rheumatic heart disease remains a major health problem in developing countries. Several factors contribute to valve-related morbidity after cardiac surgery, but the role of rheumatic etiology of valve disease is not well defined. This study was designed to determine the additional value of rheumatic valve disease in predicting morbidity after cardiac surgery in the current era of heart valve disease treatment. METHOD: This study prospectively included 164 patients for cardiac surgery from June 2010 to June 2011. The outcome was prolonged length of stay, defined as a length of stay greater than or equal to the 75th percentile for length of stay for each operation, including the day of discharge. RESULTS: Rheumatic heart disease was present in 32 patients (20%) and all rheumatic patients underwent valve replacement. Rheumatic heart disease patients were younger with less comorbidities compared to non-rheumatic patients, with most (63%) having had previous surgery. Forty-one patients were classified as having a prolonged hospital length of stay; 11 (34%) patients with rheumatic and 30 (23%) non-rheumatic fever. Rheumatic heart disease was not associated with prolonged hospital stay in the univariate analysis; however, after adjustment for other factors including infectious endocarditis, surgery duration, mechanical ventilation time, EuroSCORE, and postoperative pneumonia, it was found to be a predictor of prolonged hospitalization. CONCLUSION: This study demonstrates that rheumatic heart disease was an important factor associated with prolonged hospital, after adjustment for well-known risk factors of morbidity after cardiac surgery. Rheumatic fever is still prevalent among the patients who underwent to cardiac surgery in the current age, contributing to increase the postoperative morbidity.

OBJETIVO: A doença cardíaca reumática continua a ser um problema grave de saúde nos países em desenvolvimento. Vários fatores contribuem para a morbidade relacionada com a cirurgia valvar cardíaca, mas o papel da etiologia reumática das valvopatias não está bem definido. Este estudo foi desenhado para determinar participação adicional de valvopatias reumáticas na previsão de morbidade após cirurgia cardíaca na era atual de tratamento da doença. MÉTODOS: Este estudo incluiu prospectivamente 164 pacientes submetidos a cirurgia cardíaca, entre junho de 2010 a junho de 2011. O resultado medido foi a duração da estadia prolongada, definido como tempo de permanência maior ou igual ao percentil 75 para a duração da estada para cada operação, incluindo a dia da alta. RESULTADOS: A cardiopatia reumática esteve presente em 32 pacientes (20%) e em todos os pacientes submetidos à substituição da válvula. Pacientes com doenças cardíacas reumáticas eram mais jovens e com menos comorbidades comparados com pacientes não-reumáticos; a maioria deles (63%) tinha tido cirurgia prévia. Quarenta e um pacientes foram classificados como tendo um tempo de permanência hospitalar prolongado; 11 (34%) pacientes com doenças reumáticas e 30 (23%) com doenças não-reumáticas. A doença reumática não se apresentou associada com período de internação prolongado, na análise univariada; No entanto, após o ajuste para outros fatores, incluindo endocardite infecciosa, duração da cirurgia, tempo de ventilação mecânica, EuroSCORE, e pneumonia no pós-operatório, a doença reumática revelou-se um preditor de hospitalização prolongada. CONCLUSÕES: Este estudo demonstra que a doença cardíaca reumática é um importante fator associado com internação prolongada, após o ajuste para fatores de risco bem conhecidos de morbidade após cirurgia cardíaca. A febre reumática ainda é prevalente entre os pacientes que se submeteram à cirurgia cardíaca na época atual, contribuindo para aumentar a morbidade pós-operatória.

The effect of preoperative percutaneous transhepatic biliary drainage on postoperative short-term outcomes after pancreaticoduodenectomy / 中华肝胆外科杂志

ObjectiveTo evaluate the effect of preoperative percutaneous transhepatic biliary drainage (PTBD) on postoperative outcomes after pancreaticoduodenectomy.MethodsThe clinical data of 115 patients undergoing pancreatoduodenectomy between 2001 and 2009 were retrospectively analyzed.The diagnosis of periampullary cancer or cancer of the pancreatic head was confirmed histologically.The preoperative total bilirubin level was more than 100 μmol/L and there was no concomitant cholangitis.Forty-two patients underwent PTBD (PTBD group),and 73 were not drained (early operation group).The following parameters were analyzed:wound infection,intra-abdominal abscess,intra-abdominal or gastrointestinal bleeding,biliary or pancreatic leakage,gastroparesis,morbidity and mortality.The length of hospital stay and cost were also assessed.ResultsThe perioperative mortality and morbidity were 2.38％/54.76％ in the PTBD group and 2.74％/50.68％ in the early operative group,respectively.There were no significantly differences between these two groups.Similar results were obtained in biliary leak,pancreatic leak,intra-abdominal infection,wound infection and gastroparesis.The length of hospital stay and cost were significantly less in the early operation group than the PTBD group.ConclusionsPTBD had no beneficial effects on postoperative outcomes following pancreaticoduodenectomy.For distal biliary obstruction,PTBD should not be carried out routinely.

Clinical Study and Factors Influencing Postoperative Morbidity in Perforated Peptic Ulcer Patients

PURPOSE: After the introduction of peptic ulcer medication, a marked decrease took place in the number of patients with uncomplicated peptic ulcers subjected to elective surgery. This decline, however, was not associated with a decrease in the number of patients admitted with peptic ulcer perforation. Also, the morbidity and mortality were increased because the perforated peptic ulcers mostly occurred in elderly patients with medical illnesses. The purpose of this study was to evaluate the postoperative morbidity in patients with a perforated peptic ulcer. METHODS: Between January 2000 and December 2005, 110 consecutive patients, who underwent surgery for perforated peptic ulcer at Seoul Red Cross Hospital department of general surgery, were retrospectively reviewed. RESULTS: The overall morbidity and the mortality rates were 23.6 and 5.45%, respectively. The most common postoperative complication was postoperative ileus, followed by wound infections and pulmonary complications. The most common cause of death was sepsis. A univariate analysis showed sex, age, a delayed operation, site and size of perforation, the size of crater, comorbid diseases, and type and duration of operation were associated factors; however, the multivariate analysis showed age, a delayed operation, size of perforation, comorbid diseases, and type and duration of operation were independent risk factors. CONCLUSION: Age, a delayed operation, size of perforation, comorbid diseases, and type and duration of operation were independent risk factors for a perforated peptic ulcer. Therefore, to decrease the postoperative morbidity, comorbid diseases must be treated during the perioperative period, perforated peptic ulcer must be correctly diagnosed immediately and short time consuming operative procedures must be performed.

Resultados preliminares da oncoplástica no tratamento conservador do câncer de mama / Preliminary results of oncoplastic surgery in breast conserving-therapy

A oncoplástica (OP) associa as técnicas de cirurgia plástica à cirurgia conservadora no tratamento do câncer de mama. O seu emprego na Europa tem sido cada vez mais difundido, mas ainda existem poucos trabalhos demonstrando seus resultados em nosso meio. Assim, o objetivo deste estudo foi avaliar os resultados oncológicos e estéticos preliminares da OP em 33 pacientes consecutivas submetidas à cirurgia conservadora de mama com remodelamento bilateral por meio de técnicas de OP no ano de 2004, no Serviço de Oncologia do Hospital Nossa Senhora das Graças, em Curitiba/PR. A média de idade das pacientes foi de 51 anos. O local da mama mais freqüentemente envolvido foi a união dos quadrantes superiores (30%), e a média do tamanho tumoral foi de 15 mm. O peso médio da ressecção cirúrgica foi de 89 g, e as margens foram negativas em 85% dos casos. A maioria das pacientes foi submetida à reconstrução empregando a técnica de mamoplastia baseada no pedículo inferior (36,4%). Os resultados estéticos foram considerados bons ou excelentes em 80% dos casos. Este estudo demonstrou que a OP é segura como procedimento oncológico e com resultados estéticos satisfatórios.

Oncoplastic (OP) surgery combines breast conserving-therapy (BCT) and plastic surgery techniques. This surgery is being diffused in Europe but there are few data concerning their results in Brazil. The aim of this study was to assess the oncological and aesthetical outcomes of a consecutive series of 33 early breast cancer patients who underwent to BCT and concomitantly bilateral plastic remodeling at Surgical Oncology Division, Hospital Nossa Senhora das Graças in Curitiba in 2004. The median age of the patients was 51 years. Superior quadrants were the most frequent involved local of the breast (30%), and the medium tumor size was 15mm. The mean volume of excised specimen was 89cc. Assessment of excision margins showed complete excision in 85% of the cases. The inferior pedicle was performed for the majority of breast reconstructions (36,4%). This study confirms that OP surgery is oncologically safe and aesthetically suitable.

Laparoscopy Assisted Distal Subtotal Gastrectomy with Lymphadenectomy - 202 Consecutive Cases

PURPOSE: The number of laparoscopy-assisted distal gastrectomy procedures for the treatment of early gastric cancer patient to improve the quality of life has been gradually increasing. This study evaluated the technical feasibility, safety, and surgical results of LADG with lymphadenectomy by reviewing the initial experience. METHODS: From May 2003 to December 2005, 202 LADG with lymphadenectomy were performed on patients with a preoperative diagnosis of EGC. The clinicopathological features and surgical outcomes were analyzed. RESULTS: There were 128 males and 74 females with a mean age of 58 years (range 24~78). The mean operation time was 212 minutes (range 105~450) and the operation time has decreased gradually with increasing number of cases. There were 16 operative morbidities (7.9%) including three operative mortalities. The restoration of the bowel sound was noted at 3.1 postoperative days, soft diet was started at 4.4 postoperative days and the duration of the hospital stay was 7.7 days. There were 105 mucosal, 64 submucosal, 22 proper muscle, 4 subserosal and 7 serosal lesions. A total 163 patients were treated with D2, 37 with D1+beta and 2 with D1+alpha LN dissection. The mean number of lymph nodes retrieved was 35 (range=10~81). Lymph node metastasis was noted in 30 patients. CONCLUSION: This study shows that laparoscopic procedure can be applied safely and effectively for the patients with EGC. However, a prospective study comparing laparoscopy-assisted versus open gastrectomy for the short- and long-term surgical outcomes is needed.

Axillary Web Syndrome after Sentinel Node Biopsy and Axillary Lymph Node Dissection during the Conservative Treatment of Early Breast Cancer / 한국유방암학회지

PURPOSE: We wished to evaluate the prevalence and clinical features of axillary web syndrome (AWS) after sentinel node biopsy (SNB) and axillary lymph node dissection (ALND) during the conservative treatment of early breast cancer. METHODS: From March to November 2003, a total of 110 consecutive patients with clinical T1-T2 breast cancer underwent breast conserving surgery, with ALND being performed in 98 patients or SNB being performed in 12 patients. The diagnostic criterion for AWS was the presence of palpable and visible cords of tissue in the axilla upon maximal shoulder abduction. The extent of AWS was evaluated by inspection and by palpation of the axilla and the arm. RESULTS: Ten of 110 patients (9%) developed AWS. The AWS typically presented in the first several weeks after surgery and it resolved within 1 month of onset for all the patients. AWS was encountered for 3 patients (25%) among the patients who had SNB and for 7 patients (8%) among the ALND group, which is not statistically significant. Typically, the syndrome was self-limiting, and it resolved without any specific treatment. CONCLUSION: AWS is a significant cause of morbidity in the early postoperative period for 9% of the patients after axillary surgery. A more limited axillary surgery might help reduce the incidence and severity of the AWS.

Operative Outcome of Laparoscopy-assisted Gastrectomy with Lymph Node Dissection in 117 Consecutive Patients with Gastric Cancer: A Single-center Experience

PURPOSE: The aim of this study was to determine the feasibility and safety of laparoscopy-assisted gastrectomy (LAG) with lymph node dissection for gastric cancer according to the analysis of postoperative complications. METHODS: The authors attempted LAG with lymph node dissection in 117 consecutive patients with gastric cancer. The clinicopathologic characteristics of the patients, operative outcomes, preoperative comorbidities and postoperative morbidities and mortalities were evaluated using the stomach cancer database of Dong-A university hospital and medical charts. RESULTS: Among the 114 successful patients, 100 had early gastric cancer and 14 had advanced gastric cancer. The mean operation time was 259.2 minutes (range 150~415). The mean number of retrieved lymph nodes was 23.4 (range 6~66). The mean time to the first flatus and postoperative hospital stay were 3.7 and 10.0 days, respectively. The overall operative mortality rate, hospital death rate and the overall rate of postoperative complications were 0, 1.7 and 14.7%, respectively. The major and minor complication rate were 4.3 and 10.4%, respectively. CONCLUSION: LAG with lymph node dissection is technically feasible and receptive as surgical treatment for patients with gastric cancer, although various postoperative complications can arise in LAG as they do in open gastrectomy.

Risk Factors for Postoperative Complications of Gastric Cancer Patients

PURPOSE: The surgical techniques and postoperative care for gastric cancer have significantly improved in recent years. However, the incidence of several complications that can result in relatively increased mortality remains high. The aim of this study was to evaluate the risk factors associated with postoperative morbidity in surgery for gastric cancer. METHODS: Four hundreds and one consecutive patients, who underwent surgery for gastric cancer at National Medical Center between January 1994 and December 2002, were reviewed. RESULTS: The overall morbidity and mortality rates were 10.2 and 1.5%, respectively. A univariate analysis of multiple clinical variables revealed that age, leukocyte counts, albumin, protein, comorbid disease, combined resection, operation time, blood loss, operation type, curability, extent of lymph node dissection and stage were significantly associated with morbidity. However, a multivariate analysis showed that comorbid diseases and low curability were independent factors associated with morbidity (P<0.05). CONCLUSION: In patients with comorbid diseases and a noncurative resection, the complication rate was significantly higher. More attention should be paid to the early diagnosis, preoperative evaluation and intraoperative caution of patients with preoperative risk factors.
