Direct-to-implant breast reconstruction after bilateral mastectomy: A comparison between endoscopic and conventional open surgery / 中国胸心血管外科临床杂志

@#Objective    To compare the differences of clinical effects between the bilateral endoscopic breast reconstruction and the open breast reconstruction. Methods    The clinical data of 28 female patients who underwent bilateral breast graft reconstruction in the Department of Breast Surgery of West China Hospital from January 2017 to January 2021 were analyzed retrospectively. The patients were divided into two groups: an endoscopic group (n=12, aged 41.3±8.9 years) and an open group (n=16, aged 41.6±8.8 years). The clinical data of the two groups of patients were compared. Results     There was no significant difference in demographic and oncological data between the two groups (P>0.05). There was a significant difference in the implants between the two groups (P=0.008). The operation time (298.2±108.6 min vs. 326.5±95.8 min, P=0.480) and anesthesia time (373.4±91.2 min vs. 400.3±97.1 min, P=0.463) were not significantly different. The total complications (P=0.035) and major complications (P=0.024) in the open group were more than those in the endoscopic group. For the comparison of breast satisfaction, psychosocial well-being and sexual well-being, the scores at six months and one year after surgery were higher in the endoscopic group than those in the open group (P<0.05). Conclusion    The endoscopic reconstruction is safe and effective, with high satisfaction rates regarding  breast reconstruction and quality of life, and is superior to conventional open surgery.

¿Día o noche? El momento ideal para realizar la colecistectomía / Day or night? The right time to perform cholecystectomy

Introducción. La frecuencia de complicaciones postquirúrgicas de la colecistectomía realizada en la noche es un tema de controversia, siendo que se ha reportado una frecuencia mayor durante el horario nocturno. El objetivo de este estudio fue analizar la presentación de colecistectomía difícil dependiendo de la hora en que se realizó la cirugía, además de otras complicaciones, estancia intrahospitalaria postquirúrgica, reingreso a 30 días y reintervención. Métodos. Se realizó un estudio retrospectivo, observacional, analítico y transversal, comparando la presentación de colecistectomía difícil y su frecuencia en horario diurno (8:00 am a 7:59 pm) y nocturno (8:00 pm a 7:59 am), además de seroma, absceso, hematoma, fuga biliar, biloma, estancia intrahospitalaria postquirúrgica, reingreso a 30 días y reintervención. Resultados. Se incluyeron en el estudio 228 pacientes, 117 operados durante el día (52 %) y 111 durante la noche (48 %). La colecistectomía difícil se presentó 26 % vs 34 % de los casos intervenidos en el día y la noche, respectivamente. La complicación más frecuente fue seroma (14 %). La estancia hospitalaria media fue de 2,7 días en cirugías diurnas y de 2,5 en cirugías nocturnas; hubo 3 % de reintervenciones y 6 %, respectivamente. También hubo 2 % de reingresos a los 30 días entre los pacientes operados en el día y 3 % entre los operados en la noche. Conclusiones. La frecuencia de colecistectomía difícil y las complicaciones, la estancia intrahospitalaria postquirúrgica, el reingreso a 30 días y la necesidad de reintervención, no tuvieron diferencias significativas respecto al horario de la cirugía.

Introduction. The frequency of post-surgical complications of cholecystectomy performed overnight is a matter of controversy, and a higher rate has been reported during the night shift. The objective of this study was to analyze the presentation of difficult cholecystectomy depending on the time the surgery was performed, in addition to other complications, postoperative hospital stay, 30-day readmission, and reintervention. Methods. A retrospective, observational, analytical and cross-sectional study was carried out, comparing the presentation of difficult cholecystectomy and its frequency during daytime (8:00 am to 7:59 pm) and at night (8:00 pm to 7:59 am), in addition of seroma, abscess, bile leak, biloma, hematoma, post-surgical hospital stay, 30-day readmission, and reintervention.Results. A total of 228 patients were included in the study, 117 patients operated during the day (52%), and 111 at night (48%). Difficult cholecystectomy occurred in 26% vs. 34% of the cases operated on during the day and at night, respectively. The most frequent complication was seroma (14%). The mean hospital stay was 2.7 days in day surgeries and 2.5 in night surgeries; there were also 2% readmission at 30 days among patients operated during the day and 3% among those operated on at night. Conclusions. The frequency of difficult cholecystectomy and complications, postoperative hospital stay, 30-day readmission, and the need of reintervention, did not have significant differences with respect to the time of surgery.

Effects of transaxillary approach endoscopic and traditional open radical thyroidectomy on the levels of inflammatory factors in patients with thyroid cancer / 中国医师进修杂志

Objective:To investigate the effects of transaxillary endoscopic and traditional open radical thyroidectomy on the levels of inflammatory factors in patients with thyroid cancer.Methods:The clinical data of 102 thyroid cancer patients underwent radical thyroidectomy from October 2019 to October 2021 in Xinjiang Medical University Hospital of Chinese Medicine were retrospectively analyzed. Among them, 50 cases underwent transaxillary approach endoscopic radical thyroidectomy (study group), and 52 cases underwent open radical thyroidectomy (control group). The operation related indexes were compared between two groups, including operation time, intraoperative blood loss, postoperative drainage, lymph node clearance and hospital stay; the pain scores 1, 3 and 7 d after operation were recorded; the levels of interleukin-6 (IL-6), interleukin-10 (IL-10), galectin-3 (Gal-3) and tumor necrosis factor-α (TNF-α) before operation and 1 d after operation were measured by enzyme-linked immunosorbent assay; the postoperative complications were recorded, including hoarseness, limb numbness, cough after drinking water and hypocalcemia; and the cosmetic satisfaction was followed up 3 months after discharge, and the recurrence was observed by CT 6 months after discharge.Results:The operation time in study group was significantly longer than that in control group: (88.69 ± 15.16) min vs. (61.47 ± 15.48) min, while the intraoperative blood loss, postoperative drainage and hospital stay were significantly lower in control group: (51.21 ± 10.06) ml vs. (85.46 ± 11.37) ml, (98.29 ± 30.61) ml vs. (117.47 ± 30.25) ml and (5.35 ± 0.54) d vs. (7.72 ± 0.61) d, and there were statistical differences ( P<0.01); there was no statistical difference in lymph node clearance between two groups ( P>0.05). The pain score 1 and 3 d after operation in study group was significantly lower than that in control group: (5.13 ± 1.07) scores vs. (7.87 ± 1.46) scores and (4.22 ± 1.35) scores vs. (6.42 ± 1.28) scores, and there were statistical differences ( P<0.05); there was no statistical difference in pain score 7 d after operation between two groups ( P>0.05). There were no statistical differences in IL-6, IL-10, TNF-α and Gal-3 between two groups ( P>0.05); the IL-6, IL-10, TNF-α and Gal-3 1 d after operation in study group were significantly lower than those in control group: (26.27 ± 3.14) ng/L vs. (29.22 ± 4.52) ng/L, (7.54 ± 2.31) ng/L vs. (10.92 ± 2.54) ng/L, (14.98 ± 3.76) μg/L vs. (23.65 ± 2.46) μg/L and (3.54 ± 0.48) μg/L vs. (4.48 ± 0.63) μg/L, and there were statistical differences ( P<0.01). There was no statistical difference in the incidence of total complications between two groups ( χ2 = 1.73, P>0.05). The total satisfaction rate in study group was significantly higher than that in control group: 94.0% (47/50) vs. 78.8% (41/52), and there was statistical difference ( χ2 = 4.94, P<0.05). The patients were followed up for 6 months after discharge, and there was no recurrence. Conclusions:The transaxillary approach endoscopic radical thyroidectomy can reduce intraoperative blood loss, length of stay, postoperative drainage, postoperative pain, and to some extent inhibit inflammatory response. It can improve the postoperative cosmetic satisfaction, reduce the incidence of postoperative complications, and does not increase the recurrence rate

Open surgery in the treatment of patients with hilar cholangiocarcinoma: a study on curative efficacy and prognostic factors / 中华肝胆外科杂志

Objective:To study the efficacy of different surgical methods in treatment of hilar cholangiocarcinoma (HCCA), and to analyze the factors affecting long-term prognosis of HCCA patients after surgical treatment.Methods:The clinical data of 105 patients who underwent surgical treatment for HCCA at the First Affiliated Hospital of Soochow University from April 2010 to October 2021 were retrospectively analysed. There were 58 males and 47 females, with age (64.2±10.6) years old. Data analysed included surgical treatments, postoperative pathological data, perioperative complications and survival on follow-up. The Kaplan Meier survival curve was plotted, and the log-rank test and Cox proportional hazard model were performed to analyze the key factors affecting long-term prognosis.Results:Of 105 patients, 4 (3.8%) patients died during the perioperative period, and 58 patients (55.2%) developed complications with included 32 (30.5%) patients with pleural effusion and 12 (11.4%) patients with biliary leakage. The follow-up data was available in 85 patients with the overall median survival time of 19 months, and the 1-, 3-, 5-year cumulative survival rates of 58.1%, 27.0% and 24.8% respectively. The 1-, 3-, and 5-year cumulative survival rates for the R 0 resection patients ( n=59) were 69.4%, 36.2%, 27.4%, respectively, which were significantly better than 49.4%, 12.3%, 0% for the R 1/2 resection patients ( n=20), and 0% for the palliative drainage patients ( n=6) (all P<0.05). Univariate analysis and Cox multivariate analysis showed that age ≥70 years ( HR=2.158, 95% CI: 1.175-3.965), preoperative CA19-9 level ≥1 015 U/ml ( HR=1.981, 95% CI: 1.009-3.894), resection margin ( HR=2.587, 95% CI: 1.371-4.881), and lymph node metastasis ( HR=2.308, 95% CI: 1.167-4.567) were independent risk factors for long-term prognosis of HCCA patients (all P<0.05). Conclusions:R 0 resection was an effective way to prolong survival of patients with HCCA. Age, preoperative CA19-9 level, resection margin and lymph node metastasis were related to long-term survival of HCCA patients.

Efficacy and safety of laparoscopic versus open radical resection for hilar cholangiocarcinoma: a meta-analysis / 中华肝胆外科杂志

Objective:This article aimed to systematically evaluate the safety, feasibility and short-term outcomes of laparoscopic versus open radical resection for hilar cholangiocarcinoma.Methods:Relevant medical literatures published before November 30, 2021 were searched using PubMed, EMbase, Cochrane Library, Web of Science, CNKI, Wanfang, VIP, CBM databases. Based on predetermined inclusion and exclusion criteria, articles were selected, and RevMan5.4 software was used to conduct the meta-analysis of this study.Results:Twelve comparative cohort articles were enrolled, which included 634 patients. There were 275 patients who underwent laparoscopic radical resection for hilar cholangiocarcinoma in the laparoscopic group, and 359 patients who underwent open radical resection for hilar cholangiocarcinoma in the open group. Meta-analysis showed that when compared with the open group, operation time of the laparoscopic group was significantly longer ( MD=58.36, 95% CI:13.54-103.18). However, intraoperative blood loss ( MD=-79.70, 95% CI:-90.01--69.39), hospital stay ( MD=-3.37, 95% CI:-4.29--2.45) and incision-related complications ( OR=0.36, 95% CI:0.16-0.80) were all significantly less (all P<0.05). The number of lymph node harvested, R 0 resection rates, postoperative bile leakage, intraperitoneal infection and effusion, total complication rates, and perioperative mortality and 1-year survival rates after operation between the two groups were not significantly different (all P>0.05). Conclusion:Laparoscopic radical resection for hilar cholangiocarcinoma was feasible and safe in selected patients carried out in an experienced hepatobiliary surgery center.

Effects of laparoscopic surgery versus open surgery on acute appendicitis in children / 中国基层医药

Objective:To investigate the effects of laparoscopic surgery versus open surgery on acute appendicitis in children. Methods:We retrospectively analyzed the data of 50 children with acute appendicitis who underwent surgery in Zhoushan Women and Children Hospital from December 2016 to December 2019. They were randomly divided into observation ( n = 27) and control ( n = 23) groups. The observation group underwent three-port laparoscopy. The control group underwent open surgery. Operation-related indicators, postoperative recovery, parental satisfaction, and complications were compared between the two groups. Results:Operative time was significantly longer in the observation group than in the control group [(56.57 ± 5.35) minutes vs. (40.23 ± 6.31) minutes, t = 9.78, P < 0.001). Intraoperative blood loss was significantly less in the observation group than in the control group [(10.11 ± 2.36) mL vs. (18.36 ± 3.21) mL, t = 10.45, P < 0.001]. Duration of pain was significantly shorter in the observation group than in the control group [(1.23 ± 0.23) days vs. (2.98 ± 0.87) days, t = 10.06, P < 0.001). Time to postoperative exhaust was significantly shorter in the observation group than in the control group [(21.39 ± 4.35) minutes vs. (39.88 ±5.39) minutes, t = 13.35, P < 0.001]. Time to defection was significantly shorter in the observation group than in the control group [(50.12 ± 3.35) minutes vs. (61.23 ± 4.21) minutes, t = 10.33, P < 0.001]. Time to first diet was significantly shorter in the observation group than in the control group [(13.25 ± 2.56) hours vs. (19.96 ± 2.67) hours, t = 9.07, P < 0.001]. Length of hospital stay in the observation group was significantly shorter in the observation group than in the control group [(4.13 ± 1.12) days vs. (7.98 ± 1.96) days, t = 8.53, P < 0.001). Parental satisfaction was significantly higher in the observation group than in the control group [96.30% vs. 47.83%, χ2 = 13.360, P < 0.001]. The incidence of complications was significantly lower in the observation group than in the control group [7.41% vs. 52.17%, χ2 = 10.58, P < 0.001]. Conclusion:Laparoscopic surgery is superior and safer to open surgery in the treatment of acute appendicitis in children.

Surgery for lumbar disc herniation: open x minimally invasive technique / Cirurgia de hérnia discal lombar: técnica aberta x minimamente invasiva / Cirugía de hernia discal lumbar: técnica abierta x mínimamente invasiva

ABSTRACT Objective: In Brazil, there are no studies comparing endoscopic treatment of lumbar disc herniation with the conventional open technique in SUS (Unified Health System) with regard to hospitalization time and complications occurring within one year, which is the objective of this study. Methods: A survey of 32 surgeries performed in 2019 (11 open and 21 endoscopic) to evaluate pain parameters before and after surgery (VAS), days of hospitalization, and complications. The data were submitted to statistical analysis (ANOVA) using the Kruskal-Wallis test. Results: Fourteen patients were female and eighteen were male, with a mean age of 41.35 years (p> 0.05 between sexes). The pre- and postoperative VAS for pain radiating to the lower limb were similar between the groups: 8.5 ± 0.82 with the open technique and 8.19 ± 1.15 with endoscopic technique. In both groups there was an improvement in the pain pattern with a significant reduction in the VAS (p < 0.05) and there was no statistical relevance between the groups in terms of pain improvement. There was statistical relevance between the groups in the comparison of days of hospitalization required, with the group submitted to endoscopic surgery having a lower number of days. The complications reported were compatible with those found in the literature (postoperative dysesthesia, new herniation). Conclusions: The endoscopic technique resulted in an important reduction in the number of days of hospitalization, a factor with a high impact on the costs of any surgical procedure, which can be a determining factor in the feasibility of minimally invasive techniques. Level of evidence IV; Therapeutic Study.

RESUMO Objetivos: No Brasil, não há estudos que comparem o tratamento endoscópico de hérnia de disco lombar no SUS (Sistema Único de Saúde) com a técnica aberta convencional, no que diz respeito aos resultados com relação ao tempo de internação e complicações ocorridas em um ano, o que vem a ser o objetivo deste estudo. Métodos: Levantamento de 32 cirurgias realizadas em 2019 (11 por via aberta e 21 por via endoscópica) para avaliar os parâmetros de dor antes e depois da cirurgia (EVA), dias de internação e complicações. Os dados foram submetidos à análise estatística (ANOVA) com o teste de Kruskal-Wallis. Resultados: Catorze pacientes eram do sexo feminino e 18 do sexo masculino, com média de idade de 41,35 anos (p > 0,05 para os dois sexos). A EVA de dor irradiada para o membro inferior no pré e pós-operatório foi semelhante entre os grupos: 8,5 ± 0,82 com a técnica aberta e 8,19 ± 1,15 com a técnica endoscópica. Em ambos os grupos houve melhora do padrão de dor com redução significativa da EVA (p < 0,05) e não houve relevância estatística entre os grupos quanto à melhora do dor. Na comparação das diárias de internação necessárias houve relevância estatística entre os grupos, sendo que o grupo submetido à endoscopia teve número menor de diárias. As complicações relatadas são compatíveis com as encontradas na literatura (disestesia pós-operatória, nova herniação). Conclusões: A técnica endoscópica resultou em redução importante do número de dias de internação, fator com alto impacto nos custos de qualquer procedimento cirúrgico, que pode ser determinante para viabilizar técnicas minimamente invasivas. Nível de evidência IV; Estudo Terapêutico.

Comparative study of laparoscopic surgery and open surgery in the treatment of intrahepatic cholangiocarcinoma / 中华肝胆外科杂志

Objective:To compare the differences of short and long-term outcomes between laparoscopic surgery and open surgery treatment of intrahepatic cholangiocarcinoma patients.Methods:A retrospective cohort study was conducted to collect the clinical data of 118 patients with intrahepatic cholangiocarcinoma who underwent surgery in Qilu Hospital of Shandong University from January 2015 to June 2020. They were divided into laparoscopy group and open group according to the operation methods. The perioperative data, such as intraoperative surgical conditions, hospital costs, postoperative complications, postoperative blood biochemical tests, and the follow-up data of the two groups were compared.Results:In the laparoscopic group, there were 40 patients, 18 males and 22 females, aged (61.5±9.1) years. There were 78 patients in the open group, 48 males and 30 females, aged (61.2±8.3) years. The tumor size of the laparoscopic group was (4.4±1.8) cm, which was smaller than that of the open group (6.0±3.3) cm, and the differences were statistically significant ( P<0.05). In the laparoscopic group, 4 cases (10%) were converted to open surgery. The intraoperative blood loss, intraoperative blood transfusion proportion, 3 or more liver segments resection proportion and hospital costs of laparoscopic group were lower than those of open group [200.0(100.0, 261.8) ml vs. 300.0(100.0, 400.0) ml, 5.0%(2/40) vs. 26.9%(21/78), 37.5%(15/40) vs. 66.7%(52/78), (6.2±2.0) wan yuan vs. (7.2±2.3) wan yuan], the differences were statistically significant (all P<0.05). There were no significant differences in the incidence of postoperative complications between the two groups ( P>0.05). On the first post-operative day, ALT serum level and the third post-operative day TBil serum level in the laparoscopic group were lower than those in the open group [188.5(130.5, 274.0) U/L vs. 320.0(144.0, 427.0) U/L, 26.4(18.3, 26.4) μmol/L vs. 31.6(18.8, 37.5) μmol/l], the differences were statistically significant ( P<0.05). There were no significant differences in 1-year and 2-year overall survival rate and disease-free survival rate between the two groups ( P>0.05). Conclusion:Compared with open surgery, laparoscopic surgery in the treatment of intrahepatic cholangiocarcinoma has better short-term outcomes, and can achieve similar results in medium- or long-term outcomes.

Early and late results of open surgical and endovascular treatment of infrarenal abdominal aortic aneurysms, selected according to surgical risk / Resultados precoces e tardios dos tratamentos aberto e endovascular de aneurismas da aorta abdominal infrarrenal, selecionados de acordo com o risco cirúrgico

Abstract Background Open surgical repair (OSR) and endovascular aneurysm repair (EVAR) surgery are alternative treatments for infrarenal abdominal aortic aneurysm (IRAAA). Objectives To compare OSR and EVAR for the treatment of IRAAA. Methods 119 patients with IRAAA were electively operated by the same surgeon between January 1, 2006 and December 31, 2015, following selection for OSR or EVAR according to surgical risk. Complications, reinterventions, failures, and early and late mortality were analyzed. Results 63 OSR and 56 EVAR patients were analyzed. They were similar in terms of age (70 years), gender (92% men), and average diameter of IRAAA (6.5 cm), but with different comorbidities, surgical risk, and anatomy. EVAR was better than OSR regarding time in the operating theatre (177.5 vs. 233.3 minutes), need for transfusion (25 vs. 73%), and length of stay in ICU (1.3 vs. 3.3 days) and hospital (8.1 vs. 11.1 days). OSR allowed more associated procedures to be conducted simultaneously (19.0 vs. 1.8%). There were no significant differences between the groups with respect to complications (25.4 vs. 25.1%), reinterventions (3.2 vs. 5.2%), or early mortality (1.6 vs. 0%). During follow-up, OSR was associated with fewer revisions (3.13 vs. 4.21), angio-CTs (0.22 vs. 3.23), complications (6.4 vs. 37.5%), reinterventions (3.2 vs. 23.2%), and failures (1.6 vs. 10.7%), and had better survival (78.2 vs. 63.2%). Conclusions Correct selection of patients achieves excellent results because it avoids OSR in patients at high risk and avoids EVAR in patients with high anatomical complexity, achieving similar results in the perioperative period, but better results for OSR over the course of follow-up.

Resumo Contexto A cirurgia aberta (CA) e o reparo endovascular de aneurisma (REVA) são tratamentos alternativos para o aneurisma da aorta abdominal infrarrenal (AAAIR). Objetivos Comparar CA e REVA no tratamento do AAAIR. Métodos Foram incluídos 119 pacientes com AAAIR, operados eletivamente pelo mesmo cirurgião entre 1 de janeiro de 2006 e 31 de dezembro de 2015, após seleção para CA ou REVA de acordo com o risco cirúrgico. Complicações, reintervenções, falhas e mortalidade precoce e tardia foram analisadas. Resultados Foram analisados 63 pacientes de CA e 56 de REVA, com semelhanças de idade (70 anos), sexo (92% homens) e diâmetro médio do AAAIR (6,5 cm), mas com diferentes comorbidades, riscos cirúrgicos e anatomias. O REVA foi melhor que a CA em relação ao tempo na sala de cirurgia (177,5 vs. 233,3 minutos), necessidade de transfusão (25 vs. 73%) e tempo de permanência na unidade de terapia intensiva (1,3 vs. 3,3 dias) e no hospital (8,1 vs. 11,1 dias). A CA permitiu que mais procedimentos associados fossem realizados simultaneamente (19,0 vs. 1,8%). Não houve diferenças significativas entre os grupos em relação a complicações (25,4 vs. 25,1%), reintervenções (3,2 vs. 5,2%) e mortalidade precoce (1,6 vs. 0%). Durante o acompanhamento, a CA apresentou menos revisões (3,13 vs. 4,21), angiotomografias (0,22 vs. 3,23), complicações (6,4 vs. 37,5%), reintervenções (3,2 vs. 23,2%) e falhas (1,6 vs. 10,7%), além de ter melhor sobrevida (78,2 vs. 63,2%). Conclusões A seleção correta dos pacientes proporciona excelentes resultados porque evita pacientes com alto risco para CA e com complexidade anatômica para REVA. Os resultados são semelhantes no período perioperatório, mas melhores para CA durante o acompanhamento.

Short-term efficacy of laparoscopic gastrectomy versus open gastrectomy for advanced gastric cancer after neoadjuvant chemotherapy: a Meta-analysis / 中华消化外科杂志

Laparoscopic gastrectomy (LG) has been proven to be safe and feasible and widely used in surgical treatment of early and advanced gastric cancer (AGC), which has advantages over open gastrectomy in intraoperative bleeding and postoperative recovery. Neoadjuvant chemo-therapy (NACT) could achieve the effect of tumor downstaging and provide more surgical treatment chances for patients with AGC, thus improving their prognosis. Feasibility of LG for patients with AGC after NACT is a crucial problem for surgeons. The authors review the relevant studies and conducte a Meta-analysis to evaluate the short-term efficacy of laparoscopic versus open gastrec-tomy in the treatment of AGC after NACT.

Hybrid or open surgery for aortic arch diseases: Which one is better? / 中国胸心血管外科临床杂志

@#The conventional total arch replacement (cTAR) with frozen elephant trunk implantation is commonly regarded as the gold standard for aortic pathologies involving ascending aorta and proximal aortic arch. By combining open supra-aortic vessels debranching and emerging endovascular technologies, hybrid arch repair (HAR) has been increasingly performed as a promising alternative in risky patients with comorbidities and frailties. Nevertheless, the advantages or disadvantages of hybrid arch procedures and cTAR in terms of survival and related outcomes remain controversial. This study is aimed to briefly review the role and results of HAR in the management of aortic arch pathology in comparison of contemporary cTAR.

Thoracoscopic surgery versus traditional open surgery for infants with congenital diaphragmatic eventration: A retrospective cohort study / 中国胸心血管外科临床杂志

@#Objective    To compare and analyze the treatment effect of thoracoscopic surgery and traditional open surgery on infants with congenital diaphragmatic eventration, and summarize the experience of thoracoscopic surgery in infants with congenital diaphragmatic eventration. Methods    We retrospectively analyzed the clinical data of 105 children with congenital diaphragmatic eventration who received operation in the Department of Cardiothoracic Surgery of Children’s Hospital of Chongqing Medical University from January 2010 to January 2019. The patients were divided into an open group and a thoracoscopic group according to the operation methods. There were 41 patients in the thoracoscopic group, including 30 males and 11 females, with an average of 13.42±11.08 months (range: 1 d to 3 years). There were 64 patients in the open group, including 44 males and 20 females, with an average age of 8.21±9.33 months (range: 15.0 d to 1.6 years). The operation time, intraoperative bleeding volume, postoperative mechanical ventilation time, hospital stay and other operation indexes as well as the mortality, recurrence rate and complication rate of the two groups were observed. Results    The operation indexes such as operation time, intraoperative bleeding volume, postoperative mechanical ventilation time, thoracic drainage time, CCU stay and hospital stay of the thoracoscopic group were better than those in the open group (P<0.05). There was no statistical difference between two groups in postoperative diaphgram muscles descent, postoperative feeding time or patients needing thoracic drainage (P>0.05). The incidence of postoperative complications in the thoracoscopic group (19.51%) was lower than that in the open group (23.44%, P>0.05), and the difference in mortality and recurrence rate between the two groups was not statistically significant (P>0.05). Conclusion    Both thoracoscopic diaphragmatic plication and traditional open surgery can effectively treat congenital diaphragmatic eventration, but compared with traditional open surgery, thoracoscopic diaphragmatic plication has the advantages of shorter operation time, less trauma, more rapid recovery and fewer complications, so it should be the first choice for children with congenital diaphragmatic eventration.

Surgical management of varicose veins: a comparative analysis between radiofrequency ablation and open surgery with venous stripping

Background: Varicose veins are a common condition affecting the lower limbs. Apart from having cosmetic problem, if not treated in time it can have some serious complications and are difficult to treat. Multiple modes of surgical management exist for the disease.Methods: This is a prospective clinical study, done over a period of 5-years, between February 2015 to February 2020. Patients were divided into 2 groups: group I (n=103) included those who underwent open surgical to treatment with venous stripping. Group II (n=104) included those who subjected to Radiofrequency ablation (RFA). Groups were selected with comparable physical parameters. Various parameters like bleeding, hematoma, blood requirement, postoperative inflammation, pain, numbness, mobilization, date of discharge and resuming duties were compared. All patients were followed up for 1y ear.Results: Majority of our patients belongs to age group 20-40 years with mean age of 35year in both groups. Male has dominance over female with male to female ratio 4:1. We noticed significant complication in group I than group II, such as bleeding (20:1), hematoma (5:0), inflammation (60:1) and blood requirement (1:0). In group II, we noticed early mobilization of patient (1day v/s 3 days), discharge from hospital (1day v/s 5 days) and resuming duties (5 days v/s 2 weeks).Conclusion: RFA keeps an edge over open surgical treatment with venous stripping.

Comparative study of laparoscopic and open surgery in management of 50 cases of liver hydatid cyst

Background: Echinococcosis is caused by parasite called Echinococcus granulosus and Echinococcus multilocularis. The modern treatment of hydatid cyst of the liver varies from surgical intervention to percutaneous drainage or medical therapy.Methods: This clinical study was done on 50 patients who had liver hydatid disease admitted in Sir T Hospital, Bhavnagar from August 2013 to February 2016. Patients were divided into two groups consisting of 25 cases in each. Group A: managed by open surgery. Group B: managed by laparoscopic surgery. All patients followed up for 6 months after surgery.Results: The mean operative time in Group A was 65.2 minutes (range 35-100 minutes) while in Group B it was 76.32 minutes (range 50-100 minutes). Group B patients were mobilised early and resumed duty very fast then Group A. The mean duration of stay in hospital was 12.4 days (range 4-20 days) in Group A and  6.2 days (range 4-12 days) in Group B. Wound infection seen in 16% in Group A and 0% in Group B. General complication rate was 32% in Group A and 8% in Group B. No recurrence noticed in either group during follow up.Conclusions: Overall laparoscopic management of liver hydatid cyst is cost effective in terms of early mobilization, early discharge and early resumption of work along with cosmetic benefit.

Compare the clinical and postoperative outcomes: laparoscopic versus open surgery

Background: To assess the several postoperative complications and clinical outcomes, a retrospective comparison between laparoscopic or open surgery was performed.Methods: We evaluated patients baseline characteristics clinical characteristics, perioperative, intraoperative, inflammatory stress markers and postoperative outcomes between the two groups by univariate analysis.Results: Total 73 patients’ data were included and divided into two groups. 38 patients in first group (laparoscopic surgery) and 35 patients in second group (open surgery). There were no statistically significance differences between gender, age, weight, body mass index and type of surgery of the patients (p>0.05). There was no significant difference between groups in history of infliximab, history of steroid usage, history of appendectomy and perianal disease (p>0.05). There was no significant difference between groups in total protein, albumin, hemoglobin, skeletal muscle mass and soft lean mass. Operative time, length of incision and blood loss was significantly (p<0.001) different in both groups, respectively. Total number of complications was less in the laparoscopic surgery; however, there was no statistically significant difference. Laparoscopic surgery can shorten the hospital stay by around one day. Patients had better postoperative outcomes after laparoscopic surgery than after open surgery. No significant difference was present in edema grades between groups preoperatively. More patients developed slight edema and edema in open surgery than in laparoscopic surgery on postoperative day (POD-3), but not on POD-5.Conclusions: Laparoscopic surgery has more benefits, safe and high-quality care and better postoperative clinical outcomes for all patients compared to open surgery.

Colecistectomía subtotal: una alternativa en el manejo de la colecistectomía difícil / Subtotal cholecystectomy: an alternative in the management of difficult cholecystectomy

Introducción. Alrededor de un 10 % de las laparoscopias se convierten a cirugía abierta por dificultades en obtener una visión crítica durante la colecistectomía en colecistitis severas. La colecistectomía subtotal es una posibilidad terapéutica disponible, que disminuye la tasa de conversión en cirugía laparoscópica y mantiene bajas tasas de morbilidad y mortalidad. Métodos. Estudio descriptivo, retrospectivo, de pacientes sometidos a colecistectomía subtotal en la Clínica CES (Medellín, Colombia) entre enero y diciembre de 2015. Se identificaron variables demográficas, detalles de la cirugía, morbilidad y mortalidad. Resultados. De un total de 710 colecistectomías en dicho periodo, a 17 (2,4 %) se les realizó colecistectomía sub-total. Quince (88 %) de ellas fueron por laparoscopia y dos requirieron conversión. La distribución en cuanto a sexo fue similar (10 mujeres / 7 hombres) y la edad promedio fue de 51 años. El tiempo quirúrgico promedio fue de 119 minutos. En 14 (82 %) pacientes se dejó drenaje subhepático. Dos pacientes presentaron fístula biliar y un paciente reingresó por un hematoma; no se presentaron otras complicaciones. La estancia hospitalaria promedio fue de 5,2 días. Discusión. La colecistectomía subtotal es una alternativa en pacientes con colecistectomía difícil y en nuestra experiencia presenta una alta tasa de éxito

Introduction. About 10% of laparoscopies are converted to open surgery due to difficulties in obtaining critical vision during cholecystectomy in severe cholecystitis. Subtotal cholecystectomy is an available therapeutic possibi-lity, which decreases the conversion rate in laparoscopic surgery and maintains low morbidity and mortality rates.Methods. Descriptive, retrospective study of patients who underwent subtotal cholecystectomy between January and December 2015. Demographic variables, details of surgery, morbidity and mortality were identified.Results. Of a total of 710 cholecystectomies in that period, 17 (2.4%) underwent subtotal cholecystectomy. Fifteen (88%) of them were by laparoscopy and two required conversion. The gender distribution was similar (10 women/7 men) and the average age was 51 years. The average surgical time was 119 minutes. Subhepatic drainage was left in 14 (82%) patients. Two patients had a biliary fistula and one patient was readmitted for a hematoma; there were no other complications. The average hospital stay was 5.2 days.Discussion. Subtotal cholecystectomy is an alternative in patients with difficult cholecystectomy and in our experience, it has a high success rate

Caution is needed in interpreting the results of comparative studies regarding oncological operations by minimally invasive versus laparotomic access / É necessário cautela na interpretação dos resultados de estudos comparativos de cirurgias oncológicas por acessos minimamente invasivos vs laparotômicos

ABSTRACT We aim to alert the difference between groups while comparing studies of abdominal oncological operations performed either by minimally invasive or laparotomic approaches and potential conflicts of interest in presenting or interpreting the results. Considering the large volume of scientific articles that are published, there is a need to consider the quality of the scientific production that leads to clinical decision making. In this regards, it is important to take into account the choice of the surgical access route. Randomized, controlled clinical trials are the standard for comparing the effectiveness between these interventions. Although some studies indicate advantages in minimally invasive access, caution is needed when interpreting these findings. There is no detailed observation in each of the comparative study about the real limitations and potential indications for minimally invasive procedures, such as the indications for selected and less advanced cases, in less complex cavities, as well as its elective characteristic. Several abdominal oncological operations via laparotomy would not be plausible to be completely performed through a minimally invasive access. These cases should be carefully selected and excluded from the comparative group. The comparison should be carried out, in a balanced way, with a group that could also have undergone a minimally invasive access, avoiding bias in selecting those cases of minor complexity, placed in the minimally invasive group. It is not a question of criticizing the minimally invasive technologies, but of respecting the surgeon's clinical decision regarding the most convenient method, revalidating the well-performed traditional laparotomy route, which has been unfairly criticized or downplayed by many people.

RESUMO Objetivamos alertar a desigualdade entre grupos de pacientes, em estudos comparativos de cirurgias oncológicas abdominais por acessos minimamente invasivos ou laparotômicos, e os possíveis conflitos de interesse na demonstração ou interpretação dos resultados. Diante do grande volume de artigos científicos produzidos, há necessidade de se considerar a qualidade da produção científica de estudos para a tomada da decisão clínica quanto à eleição da via de acesso cirúrgico. Ensaios clínicos randomizados e controlados são o padrão para comparar a eficácia entre estas intervenções em situações diversas. Apesar de alguns estudos indicarem vantagens no acesso minimamente invasivo, é preciso cautela na interpretação desses achados. Não se percebe detalhada discussão que alerte, em cada estudo comparativo, sobre os reais limites e indicações possíveis de cirurgias minimamente invasivas, como indicações para casos selecionados, menos avançados, mais eletivos, e em cavidades menos complexas. Diversas cirurgias oncológicas abdominais via laparotômica não seriam plausíveis de serem, completamente, realizadas por acesso minimamente invasivo. Estas deveriam ser, criteriosamente, selecionadas e excluídas do grupo comparativo. A comparação deve ser, equilibradamente, realizada com grupo que, muito provavelmente, também poderia ter sido submetido ao acesso minimamente invasivo a contento, evitando viés de seleção da concentração de casos de complexidade menor no grupo da cirurgia minimamente invasiva. Não se trata, aqui, de desmerecer as tecnologias minimamente invasivas, mas de respeito à decisão clínica do cirurgião pelo método mais conveniente, revalidando a via laparotômica tradicional bem procedida, a qual tem sido, injustamente, criticada ou inferiorizada por muitos em nosso meio.
