ABSTRACT
ABSTRACT BACKGROUND: Morbidity of liver resections is related to intraoperative bleeding and postoperative biliary fistulas. The Endo-GIA stapler (EG) in liver resections is well established, but its cost is high, limiting its use. The linear cutting stapler (LCS) is a lower cost device. AIMS: To report open liver resections, using LCS for transection of the liver parenchyma and en bloc stapling of vessels and bile ducts. METHODS: Ten patients were included in the study. Four patients with severe abdominal pain had benign liver tumors (three adenomas and one focal nodular hyperplasia). Among the remaining six patients, four underwent liver resection for the treatment of colorectal liver metastases, three of which had undergone preoperative chemotherapy. The other two cases were one patient with metastasis from a testicular teratoma and the other with metastasis from a gastrointestinal neuroectodermal tumor. RESULTS: The average length of stay was five days (range 4-7 days). Of the seven patients who underwent resections of segments II/III, two presented postoperative complications: one developed a seroma and the other a collection of abdominal fluid who underwent percutaneous drainage, antibiotic therapy, and blood transfusion. Furthermore, the three patients who underwent major resections had postoperative complications: two developed anemia and received blood transfusions and one had biloma and underwent percutaneous drainage and antibiotic therapy. CONCLUSIONS: The use of the linear stapler in hepatectomies was efficient and at lower costs, making it suitable for use whenever EG is not available. The size of the LCS stapler shaft is more suitable for en bloc transection of the left lateral segment of the liver, which is thinner than the right one. Further studies are needed to evaluate the safety of LCS for large liver resections and resections of tumors located in the right hepatic lobe.
RESUMO RACIONAL: A morbidade das ressecções hepáticas está relacionada a sangramento intraoperatório e fístulas biliares pós-operatórias. O grampeador Endo-GIA (EG) em ressecções hepáticas está bem estabelecido, mas o seu custo é elevado, limitando seu uso. O grampeador de corte linear (LCS) é um dispositivo com menor custo. OBJETIVOS: Relatar ressecções hepáticas abertas, empregando o LCS para transecção do parênquima hepático e grampeamento em bloco de vasos e ductos biliares. MÉTODOS: Dez pacientes foram incluídos no estudo. Quatro pacientes com dor abdominal importante apresentavam tumores hepáticos benignos (três adenomas e um hiperplasia nodular focal). Dentre os demais seis pacientes, quatro foram submetidos à ressecção hepática para o tratamento de metástases hepáticas colorretais, sendo que três deles haviam sido submetidos à quimioterapia pré-operatória. Os dois outros casos foram um paciente com metástase de teratoma testicular e o outro com metástase de tumor neuroectodérmico gastrointestinal. RESULTADOS: O tempo médio de internação foi de 5 dias (variação=4-7 dias). Dos sete pacientes submetidos a ressecções dos segmentos II/III, dois apresentaram complicações pós-operatórias: um paciente desenvolveu seroma e o outro uma coleção de fluido abdominal submetido a drenagem percutânea, antibioticoterapia e transfusão de sangue. Além disso, os três pacientes submetidos a ressecções maiores tiveram complicações pós-operatórias: dois pacientes desenvolveram anemia e receberam transfusões de sangue e um paciente apresentou biloma e foi submetido a drenagem percutânea e antibioticoterapia. CONCLUSÕES: O emprego do grampeador linear nas hepatectomias foi eficiente e a custos mais baixos, tornando-o adequado para uso sempre que EG não estiver disponível O tamanho da haste do grampeador LCS é mais adequado para a transecção em bloco do segmento lateral esquerdo do fígado, que é mais fino que o direito. Novos estudos são necessários para avaliar a segurança do LCS para grandes ressecções hepáticas e ressecções de tumores localizados no lobo hepático direito.
ABSTRACT
ABSTRACT - BACKGROUND: Stapled hemorrhoidopexy has been widely used for the treatment of hemorrhoids, but concerns about complications and recurrences after prolonged follow-up are still under debate. AIMS: The aim of this study was to evaluate the very long-term results of the stapled hemorrhoidopexy technique. METHODS: Stapled hemorrhoidopexy was performed on 155 patients between 2000 and 2003, and the early results have already been published. In this study, we evaluated the same patients after a very long follow-up. Data were collected with regard to late complications, rate and timing of recurrences, and patients' degree of satisfaction. RESULTS: From a total of 155 patients, 98 patients were evaluated: 59 (60.2%) were interviewed by telephone and 39 (39.8%) were evaluated by outpatient consultation. The mean follow-up was 193 months (range: 184-231), 52 were female, 52 were grade III hemorrhoids, and 46 were grade IV. Recurrence was higher in grade IV (26.1%) than in grade III (7.7%) (p=0.014). Recurrence after prolonged follow-up was seen in 16 patients (16.3%) and 11 (11.2%) required reoperations. The complications were skin tags (3.1%), anal sub-stenosis (2.1%), and fecal incontinence (2.1%). After a prolonged follow-up, 82.5% of patients were either very satisfied or satisfied with the surgery. CONCLUSIONS: Stapled hemorrhoidopexy is a safe and effective treatment for hemorrhoidal disease grades III and IV. Recurrence is higher for grade IV hemorrhoids and may occur up to 9 years of follow-up. Reoperations were infrequent and there is a high patient's degree of satisfaction associated with this technique.

O seguimento médio foi de 193 meses (variação: 184-231), 52 eram do sexo feminino, 52 eram hemorroidas grau III e 46 eram grau IV. A recorrência foi maior no grau IV (26,1%) do que no grau III (7,7%) (p=0,014). A recorrência após seguimento prolongado foi observada em 16 pacientes (16,3%) e 11 (11,2%) necessitaram de reoperações. As complicações foram: plicomas (3,1%), subestenose anal (2,1%) e incontinência fecal (2,1%). Após seguimento prolongado, 82,5% dos pacientes ficaram muito satisfeitos ou satisfeitos com a cirurgia. CONCLUSÕES: O hemorroidopexia mecênica é um tratamento seguro e eficaz para a doença hemorroidária graus III e IV. A recorrência é maior para hemorroidas grau IV e pode ocorrer até 9 anos de seguimento. As reoperações foram infrequentes e há um alto grau de satisfação do paciente associado a esta técnica.
ABSTRACT
Obesity has been considered a chronic relapsing disease. The increasing number of obese individuals has resulted in an increase in the demand for bariatric surgeries annually. Post-laparoscopic sleeve gastrectomy complications are challenging for both patients and surgeons. Thus, this paper reviews the most common and significant risk factors for leakage occurrence after laparoscopic sleeve gastrectomy and presents new tools, techniques, management options, and recommendations, gathered from newly published articles, for post-laparoscopic sleeve gastrectomy leakage. Causes of post-laparoscopic sleeve gastrectomy leakage include technical factors such as bougie size, transection point, reinforcement materials, and patient co-morbidities as well as ischemic reasons. Ischemic leakage, which is most commonly seen in laparoscopic sleeve gastrectomy, occurs usually after the fourth day, although some leakage may appear earlier within 1-3 days due to technical issues. Use of varied bougie sizes results in similar excess weight loss % at the one-year follow-up. Buttressing materials also reduce post-laparoscopic sleeve gastrectomy bleeding, but not the leakage rate. Endoscopic stents play a significant role in gastric leakage treatment in post-laparoscopic sleeve gastrectomy patients. Intra-operative or even early postoperative diagnostic tools can help in detecting early leaks, but minor leaks as well as those due to ischemic causes may be missed. In conclusion, laparoscopic sleeve gastrectomy is still one of the most effective bariatric surgeries, exhibiting approximately 70% excess weight loss. Although complications of post-laparoscopic sleeve gastrectomy are severe and may be life-threatening, most patients can be treated conservatively. However, those with persistent fistula require surgical intervention.

Background– The use of circular staplers in the treatment of hemorrhoidal disease is known as a simple procedure, with low morbidity, less post–treatment pain and with the same efficacy when compared to the classical hemorrhoidectomy. Aim– Analyze the operative technique, intra–operative and immediate postoperative complications and late results in 100 patients treated for hemorrhoid disease by stapling technique. Patients and Methods– The group included 53 males and 47females with mean age of 49.8 years, operated during the period June 2015 to June 2017 in the Tertiary Care Centre– SKNMC and GH. Results– The majority of patients (78%) were discharged on the first post–operative day. Eight patients required supplementary analgesia and were given intramuscular diclofenac sodium and four of them received intramuscular tramadol. The postoperative follow–up displayed: recurrence of prolapse, five cases (5%); anal sub–stenosis, two cases (2%); anal fissure, one case (1%); persistent pain, two cases (2%). Seven reoperations were performed: one due to bleeding, one due to sub–stenosis and five due to recurrence of hemorrhoidal prolapse and persistence of symptoms. Conclusion– Stapling is simple to accomplish, has low postoperative pain and rate of complications.
ABSTRACT
Objective To compare the clinical effect of two-person operations of disposable circumcision stitching instrument and one-man operations of disposable circumcision stitching instrument.Methods Clinical data of 340 patients with redundant prepuce or phimosis from March 2015 to August 2017 were randomly divided into control group which patients with two-person operation of disposable circumcision stitching instrument and study group which patients with one-man operation of disposable circumcision stitching instrument were reviewed prospectively.There were 188 patients in the study group,including 22 patients with phimosis and 166 patients with redundant prepuce;Among the 152 patients in the control group,there were 17 cases with phimosis and 135 cases with redundant prepuce.Two groups with operation time,intraoperative blood loss,postoperative skin staple missing,2 hours postoperative pain,postoperative edema,the swelling subsided time,postoperative complications,postoperative patient satisfaction,and so on.Measurement data were represented as (x) ± s,and comparison between groups was analyzed using t test;count data were represented as percentage and comparison between groups was analyzed chi-square.Results All operations were finished successfully for the patients by two-person or one-man of operations of disposable circumcision stitching instrument.In terms of operation,the operation time of the observation group and the control group was (7.76 ±0.45) minutes and (7.86 ±0.91) minutes respectively,and the difference was not statistically significant(P ＞ 0.05).Intraoperative hemorrhage of observation group and control group were (1.77 ± 0.22) ml and (1.72 ± 0.26) ml,and the difference was not statistically significant (P ＞ 0.05).There was no statistically significant difference between the observation group and the control group (P ＞ 0.05) in the postoperative 2 hours pain score and skin staple missing.In the postoperative complications,the deviation rate of the prepuce was 1.11％,significantly lower than the control group 5.92％,and the difference was statistically significant (P ＜ 0.05).There was no statistically significant difference between the observation group and the control group in terms of edema on the third postoperative day,short postoperative anastomosis,patient satisfaction,and postoperative infection.Conclusion The way of one-man operation of disposable circumcision stitching instrumente not only saves labor costs,but also has a good postoperative clinical effect,meanwhile,it has high efficiency and strong operability,and is worthy of promotion for clinical first-line urologists.
ABSTRACT
RESUMO Objetivo: avaliar o impacto na fisiologia anorretal da hemorroidopexia por grampeamento parcial, das complicações relacionadas à técnica cirúrgica, dor e sangramento pós-operatório e recidiva de doença hemorroidária após um ano de cirurgia. Métodos: estudo prospectivo, descritivo, em pacientes consecutivos, portadores de doença hemorroidária do tipo mista ou interna, com componente interno classificado como grau III ou IV, submetidos à hemorroidopexia por grampeamento parcial. Resultados: foram estudados 17 pacientes, dos quais 82% apresentavam hemorroidas internas grau III, e 18% grau IV. A média de tempo operatório foi de 09:09 minutos (07:03 a 12:13 minutos). A mediana de dor no pós-operatório imediato avaliada pela escala numérica de dor foi de 1 (0 a 7). A mediana de retorno ao trabalho foi de nove dias (4 a 19). Nenhum paciente apresentou estenose de canal anal e 76% ficaram satisfeitos com a cirurgia com 90 dias de pós-operatório. Comparando-se os dados manométricos pré-operatórios e após 90 dias, nenhuma das variáveis avaliadas apresentou diferença com significância estatística. Não houve recidiva da doença hemorroidária com um ano de acompanhamento pós-operatório. Conclusão: a hemorroidopexia por grampeamento parcial não demonstrou impacto na fisiologia anorretal, apresentando baixos níveis de complicações e de dor pós-operatória, e sem recidivas após um ano de acompanhamento.
ABSTRACT Objective: to evaluate the impact of partial stapled hemorrhoidopexy on anorectal physiology, the complications related to this surgical technique, pain, postoperative bleeding and recurrence of hemorrhoidal disease one year after surgery. Methods: this is a prospective, descriptive study in consecutive patients with mixed or internal hemorrhoidal disease, the internal component being classified as grade III or IV, undergoing partial stapled hemorrhoidopexy. Results: we studied 17 patients, 82% of them with internal hemorrhoids grade III and 18% grade IV. The mean operative time was 09:09 minutes (07:03 to 12:13). The median pain in the immediate postoperative period evaluated by the numerical pain scale was one (0 to 7). The median time to return to work was nine days (4 to 19). No patient had anal stenosis and 76% were satisfied with the surgery 90 days postoperatively. When comparing the preoperative manometry data with that measured 90 days after surgery, none of the variables studied showed statistically significant difference. There was no recurrence of hemorrhoidal disease with one year of postoperative follow-up. Conclusion: partial stapled hemorrhoidopexy showed no impact on anorectal physiology, presenting low levels of complications and postoperative pain, without recurrence of hemorrhoidal disease in one year of follow-up.

ABSTRACT
BACKGROUND:Col agen suture is made of col agen from animals, and has been widely used because it is absorbable, non-rejection and easy to produce, and convenient in use. OBJECTIVE:To evaluate the effects of col agen suture and silk suture in wound healing after oral implant surgery. METHODS:100 patients undergoing oral implantation were randomly assigned into col agen suture group and silk suture group. A 2-0 circular needle with absorbable col agen sutures and a 4-0 circular needle with non-absorbable silk sutures were employed for tension-free suture in the two groups. After 3, 5, 7 days of oral implantation, suture threads and wound healing were observed. The suture was removed at 14 days, and patients were reviewed at 14 days. RESULTS AND CONCLUSION:The wound healing was better in the col agen suture group than the silk suture group at grade I (P<0.05). At 7 days postoperatively, the suture thread was mostly absorbed in the col agen group but not in the silk suture group. In addition, material alba was invisible in the col agen suture group but clear in the silk suture group. These results indicate that the col agen suture is more proper for tension-free suture than the silk suture, which is better matched to the healing time and keeps a better oral environment.
ABSTRACT
Objective To evaluate the safety and efficacy of Perclose device after cerebral angiography or intervention procedures. Methods Two hundred and eighty-nine patients who underwent cerebral angiography or intervention procedure were divided into two groups: 143 patients accepted Perclose device for hemostasis (device group), 146 patients accepted manual method for hemostasis (handwork group). Time to achieve hemostasis and ambulation,complications associated with the procedure,the rates of successful hemostasis and patients' discomfort were compared. Results The rates of successful hemostasis were 96.5%( 138/143) in the device group and 97.9%( 143/146) in the handwork group (P> 0.05). Time to achieve hemostasis and ambulation in the device group were (3.13 ± 2.17) min and (1.99 ± 1.11) h ,they were shorter than those in the handwork group [(15.91 ± 3.27) min and (17.93 ± 7.82) h](P< 0.01). The occurrence rate of complication at the femoral access site and patients' discomfort rates from staying in bed in the device group were lower than those in the handwork group (P < 0.01). There were 7 cases of large hematoma and 1 case of pseudoaneurysm in the handwork group. Conclusions The use of Perclose device is a safe and effective method for hemostasis of the femoral access site after cerebral angiography and intervention. It could shorten the time of staying in bed and decrease vascular complications significantly.
ABSTRACT
OBJETIVO: Os autores apresentam um estudo observacional, transversal, comparando a anastomose manual com a anastomose mecânica para reconstrução do trânsito digestivo em Y de Roux em pacientes submetidos à gastrectomia total para câncer gástrico. MÉTODOS: O estudo foi realizado no Hospital Governador Israel Pinheiro, no período de janeiro de 1997 a março de 2002. Um total de 40 pacientes neste período foram submetidos à gastrectomia total com reconstrução em Y de Roux. O Grupo I formado por 16 pacientes foi submetido à anastomose mecânica e o grupo II por 24 pacientes foi submetido à anastomose manual. Os dois grupos foram comparados quanto à incidência de complicações pós-operatórias, necessidade de re-operação, alta hospitalar e mortalidade per e pós-operatória. RESULTADOS: Quanto às complicações relacionadas à anastomose, fístula e abscesso intra-abdominal, elas ocorreram em nove pacientes do grupo com anastomose manual e em nenhum paciente no grupo com anastomose mecânica. (p= 0,006). A morbidade e a permanência hospitalar pós-operatória foram maiores no grupo submetido à sutura manual. Houve um óbito em cada grupo e 37 por cento dos pacientes em cada grupo não apresentaram quaisquer tipos de complicações. CONCLUSÃO: Considerando a fístula e o abscesso intra-abdominal juntamente como complicações da anastomose esôfago-jejunal, os resultados deste estudo sugerem uma maior viabilidade da sutura mecânica.
BACKGROUND: The authors report a observational study comparing the surgical outcomes in patients underwent total gastrectomy for gastric cancer and Roux-en-Y end-to-end esophagojejunostomy. METHODS: A mechanical EEA stapler or conventional manual suturing was used. The study was realized in Israel Pinheiro Governor Hospital from January 1997 to May 2002. The surgical outcomes of 16 patients in whom stapling was used (stapler group) and 24 patients in whom manual suturing was done (manual group) were compared. They were: complications incidence, re-operation, hospital stay and mortality. RESULTS: In each group, 37 percent of patients did not have any kind of complications. About anastomotic complications (leakage and intraabdominal abscess), there was 9 in manual group and anyone in mechanical group (p=0,006). Morbidity and hospital stay were higher in manual group. There was one obit in each group. CONCLUSION: Surgical complications, morbidity and hospital stay were higher in manual group. This study suggest a higher viability of mechanical suturing.
ABSTRACT
BACKGROUND: Introduction of stapled hemorrhoidopexy by Longo in 1998 represented a radical change in the treatment of hemorrhoids. By avoiding multiple excisions and suture lines in the perianal region, stapled hemorrhoidopexy is intended to offer less postoperative pain than with conventional techniques. OBJECTIVE: To report and analyze the intra and postoperative results gained during initial experience with stapled hemorrhoidopexy. METHODS: One hundred and fifty five patients (67 males) with average age of 39.5 years (21-67 years) underwent stapled hemorrhoidopexy between June 2000 and December 2003 with symptomatic third-degree (n = 74) and fourth-degree (n = 81) hemorrhoids. Mean follow-up period was 20 months (14-60 months). RESULTS: Preoperative symptoms were prolapse (96.7 percent) and anal bleeding (96.1 percent). Overall mean operative time was 23 minutes (16-48 minutes). We observed one case of stapler failure and one case of failure to introduce the stapler occurred in a patient with previous anal surgery. Additional sutures for hemostasis were required in 103 patients (66.5 percent). Resection of skin tags was performed in 45 cases (29 percent). Postoperatively scheduled analgesia with oral dipyrone and celecoxib was enough for pain control in 131 patients (84.5 percent). Rescue analgesia was necessary in 24 cases (15.5 percent). Five patients needed opiates for pain control. Hospital discharge took place on the first postoperative day in 140 patients (90.3 percent). First defecation without pain was reported by 118 patients (76.1 percent). Postoperative complications were anal bleeding (10.3 percent), severe pain (3.2 percent), urinary retention (3.9 percent), fever without any signs of perianal infection (1.9 percent), incontinence for flatus (1.9 percent), hemorrhoidal thrombosis (1.3 percent). Two patients presented symptoms of recurrent hemorrhoidal disease and were successfully treated by conventional hemorrhoidectomy. They were no cases of...
RACIONAL: A introdução por Longo em 1998, da hemorroidopexia pela técnica de grampeamento circular representou uma mudança radical no tratamento cirúrgico da doença hemorroidária, ao passo que propõe o reposicionamento da mucosa anorretal prolapsada, sem excisão do mamilo hemorroidário, cursando assim com menor dor e menor tempo de recuperação pós-operatórios. OBJETIVO: Apresentar e analisar os resultados intra e pós-operatórios obtidos durante a experiência inicial com a técnica de grampeamento circular. PACIENTES E MÉTODO: Foram incluídos 155 pacientes (67 homens) com média de idade de 39,5 anos (21-67 anos) e doença hemorroidária sintomática grau III (n = 74) e IV (n = 81), operados consecutivamente pelo método do grampeamento circular entre junho de 2000 e dezembro de 2003. Resultados e complicações pós-operatórias foram aferidos num tempo de seguimento médio de 20 meses (14-60 meses). RESULTADOS: Os principais sintomas pré-operatórios foram prolapso (96,7 por cento) e sangramento (96,1 por cento). O tempo operatório médio foi de 23 minutos (16-48 minutos). Houve um caso de falha do equipamento e um de impossibilidade de introdução do mesmo (paciente com cirurgia anal prévia). Hemostasia adicional com sutura foi necessária em 103 pacientes (66,5 por cento) e a ressecção de plicomas foi realizada concomitantemente ao procedimento em 45 pacientes (29 por cento). A analgesia pós-operatória via oral com dipirona e celecoxib foi eficiente no controle da dor em 131 pacientes (84,5 por cento), 24 (15,5 por cento) necessitaram de analgesia complementar, sendo que 5 pacientes receberam opióides devido a dor intensa. A maioria dos pacientes (140 - 90,3 por cento) teve alta no primeiro dia de pós-operatório e 118 (76,1 por cento) referiram a primeira evacuação sem dor. As complicações pós-operatórias observadas foram: sangramento (10,3 por cento), tenesmo (3,9 por cento), retenção urinária (3,9 por cento), febre sem sinais infecciosos (1,9 por cento), incontinência...

ABSTRACT
BACKGROUND: Thoracoscopic bullectomy (VATS-B) is now the preferred treatment for spontaneous pneumothorax despite of higher recurrence rate than open thoracotomy. Several methods have been used to prevent this problem. The effectiveness of staple line reinforcement (SLR) in VATA-B using endostaplers was assessed by clinical and experimental study. MATERIAL AND METHOD: In experimental study, canine lungs were harvested immediately (group I, N=5) and 48 hours (group II, N=5) after stapling. The pressures at which initial air leaks occurred were measured. In clinical study from February 1997 to March 1999, 106 procedures in 104 patients undergoing VATS-B for spontaneous pneumothorax were classified into two groups according to the presence of SLR and were compared. RESULT: The average pressure of the initial air leakage was significantly higher in SLR than that of staples alone (18+/-1.6 vs 48+/-3 mm Hg in group I; 23.8+/-1.9 vs 54+/-4.6 mm Hg in group II, p<0.001). In the clinical data, there were significant differences seen in the duration of drainage, the total length of endostaplers used, and the duration of the postoperative hospital stay between patients with staple alone and patients with SLR (4.4+/-1.4 vs 3.1+/-1.1 days in duration of drainage, 92.3+/-28.1 vs 71.1+/-30.6 mm in total length of endostaplers used, 5.9+/-1.9 vs 4.6+/-1.7 days in postoperative hospital stays, p<0.001). CONCLUSION: SLR was effective for preventing prolonged air leakage and responsible for shorter hospital stays after VATS-B for the treatment of spontaneous pneumothorax.
