Impact of the vertical division of the rectum on the decrease in reloading of the endostapler for a complete division in colorectal cancer

Background: Despite several improvements in surgical techniques, the intracorporeal division of the distal end of the rectum is still challenging, particularly when it is too deep in a narrow pelvis. Even though it helps avoid spillage, the double-stapling technique (DST) raises concerns regarding safety and anastomotic leakage if multiple stapler firings are essential to complete the rectal division. Objective: To assess the feasibility of vertically dividing the rectum and its impact in reducing the number of reloads essential for that division in non-low rectal cancer patients undergoing total mesorectal excision (TME). Materials and Methods A retroprospective study. Results: From January 2017 to November 2021, a total of 123 patients with sigmoid and rectal cancers were enrolled in the present study; their data were collected and analyzed, and 21 patients were excluded. The remaining sample of 102 subjects was composed of 47 male (46%) and 55 female (54%) patients with a median age of 54 years (range: 30 to 78 years). Only 1 reload was enough to complete the rectal division in 82 (80.39%) cases, and 2 reloads were used in the remaining 20 (19.61%) patients. Anastomotic leakage was clinically evident in 4 cases (3.9%). No statically significant difference was observed when firing one or two staplers. No 30-day mortality was recorded in this series. Conclusion: Our early experience indicates that this type of division has a real advantage in terms of decreasing the number of reloads needed and, in turn, lowering the incidence of anastomotic leakage after partial mesorectal excision (PME) or TME when applied with proper patient selection.

Total Laryngectomy with Horizontal Mechanical Closure of the Pharyngoesophagectomy: Evaluation of the Effectiveness in Elderly Patients

Abstract Introduction The main modalities of surgical treatment for laryngeal cancer include transoral laser microsurgery (TLM), open preservation surgery, and total laryngectomy (TL). In the elderly, for the presence of comorbidities, the surgical approach more appropriate in many cases remains TL. The use of a stapler for the closure of the esophagus has been introduced to reduce surgical time and postoperative complications such as pharyngocutaneous fistula (PCF). Objective In the present study, we have evaluated the effectiveness of the use of the horizontal mechanical pharyngoesophageal closure in patients who underwent TL. Methods This nonrandomized study was performed on consecutive patients with histopathologically proven squamous cell endolaryngeal carcinoma. The TLwas performed using a linear stapler to mechanically suture the pharyngotomy using the semiclosed technique. Results A total of 33 patients underwent TL, and 13 of themunderwent neck dissection. A total of 15 patients (45.4%) were ≤70 years old, and 18 were > 70 years old. Analyzing the results in relation to age, patients > 70 years old showed tumors at an earlier stage than those aged ≤70 years old. Furthermore, in this group there was a greater number of patients who had comorbidities (p = 0.014). In total, we had 2 (6%) cases of PCF in 6.6% in the group ≤70 years old, and in 5.5% of the group > 70 years old (p = 1.00). Conclusions The use of the stapler for the horizontal closure of the pharyngoesophagectomy in the patients subjected to TL is proven to be useful and safe even when used in elderly patients.

Common operation, uncommon complication. Bleeding from superior haemorrhoidal artery after minimally invasive procedure for hemorrhoids - a case report / Operação comum, complicação incomum. Sangramento de artéria hemorroidária superior após PMIH - um relato de caso

ABSTRACT Minimally invasive procedure for hemorrhoids is one of the commonest new wave operations done for prolapsed hemorrhoids. The diameter of the stapled tissue is critical in this operation, and an increase in the same could include more tissue in the anvil, with disastrous results. This is a case report of a post minimally invasive procedure for hemorrhoids bleed, which was refractory to two local oversewing attempts. When the bleeding was massive, an angiogram was obtained. This revealed a pseudo aneurysm of the left superior haemorrhoidal artery, which was embolized, stopping the bleed. The stapler dimensions were studied and the possible cause of the event was arrived at. The specific stapler used had a diameter of 2 mm more than the regular Medtronic and Ethicon staplers, possibly including more of the rectal wall, and the superior haemorrhoidal artery as well. This case report documents a rare and potentially fatal complication of a simple procedure.

RESUMO O procedimento minimamente invasivo para as hemorroidas (PMIH) é uma das novas operações mais comuns para ao tratamento de hemorroidas prolapsadas. O diâmetro do tecido grampeado é crítico nessa operação; um aumento nesse diâmetro poderia colocar mais tecido na bigorna do grampeador, com resultados desastrosos. Este relato de caso descreve o desfecho de uma hemorragia após PMIH, refratária a duas tentativas locais de sobressutura. Um angiograma foi realizado quando a hemorragia foi considerada intensa. O exame revelou um pseudoaneurisma da artéria hemorroidária superior esquerda, que foi embolizada, interrompendo o sangramento. As dimensões do grampeador foram estudadas e descobriu-se a possível causa do evento. O grampeador específico usado tinha um diâmetro 2 mm maior do que os grampeadores regulares da Medtronic e da Ethicon e possivelmente captou uma área maior da parede retal e a artéria hemorroidária superior. Este relato de caso documenta uma complicação rara e potencialmente fatal de um procedimento simples.

The Causes, Prevention, and Management of Gastric Leakage after Laparoscopic Sleeve Gastrectomy: A Review Article

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.

Is there difference in chronic pain after suture and stapler fixation method of mesh in ventral hernia? a randomized controlled trial

Background and Objective: Chronic pain occurs in 20-30% of patients after hernia surgery. As a consequence of this chronic pain, almost one third of patients have limitations in daily activities. Frequency and severity of this pain varies with different techniques of hernia repair. The objective of this study was to compare polypropylene suture and skin staples for securing mesh in uncomplicated ventral hernioplasty in terms of acute and chronic postoperative pain and to compare the time taken for mesh fixation between polypropylene sutures and skin stapler in ventral hernioplasty

Methods: This study was conducted in Surgery Department of Dow University Hospital, Dow University of Health Sciences, Ojha Campus and included 53 patients from Jan 2015 to Dec 2016, after taking informed consent. All patients were operated under general anesthesia by the same surgical team. Patients were randomized into two groups; in one group mesh fixed with 2/0 polypropylene suture while in other group mesh stapler was used. Time taken to apply mesh was noted in minutes from laying the mesh over anterior rectus sheath to completion of fixation by either method. The severity of post-operative pain was measured with VAS [1-10] after one week, one month and after one year after surgery. Data was analysed using SPSS version 17

Results: Patient characteristics and operative outcome were similar in the two groups and statistically non-significant in both. Early postoperative pain was more after suture fixation but it was not statistically significant. Mean +/- SD pain score was after one week 3.47 +/- 2.7 after sutures while 2.91 +/- 1.88 after stapler. After four weeks, 0.40 +/- 0.49 after suture while 0.35 +/- 0.48 after stapler fixation. In both study groups 30-34% of the patients felt some pain in follow-up after one year. Severity of pain was 0.60 +/- 0.62 after suture while 1.65 +/- 1.94 after stapler fixation which is statistically significant as well [p<0.007]. Mean operative time was 15.33 +/- 6.33 minutes for suture fixation while 1.56 +/- 0.41 minutes for fixation by staples, p-value < 0.001

Conclusion: The method of fixation does not appear to cause significant difference in early postoperative pain but chronic pain is more after stapler fixation of mesh. However, operative time was reduced significantly in staple fixation group as compared to suture fixation group

A novel approach to lower rectal anastomosis: technique innovation and the preliminary report of twenty cases / Uma nova abordagem para a anastomose retal mais baixa: inovação técnica e relatório preliminar de cinte casos

Background and aims: To describe a practical technique innovation (transanal 'Pull-through' approach) as a feasible, safe and effective alternative to the conventional transabdominal stapler low rectal anastomosis in lesions of minimal anatomical distinction from the adjacent intact mucosa. Material and methods: Prospective case-series of patients with low rectal cancers, familial adenomatous polyposis (FAP) and ulcerative colitis undergoing Pull-through transection and very low rectal anastomosis using linear TA-90 noncutting stapler and circular stapler-cutter. Results: In this series, twenty patients (11 men and 9 women) underwent proctectomy by the transanal Pull-through technique. Barring one of the patients that developed a pelvic abscess in the immediate postop follow-up, surgical procedure and the long-term follow-up period was uncomplicated with no critical findings of leakage, stenosis and bleeding. The postop rate of infection and fecal incontinence was not significantly different between genders and different age groups of the study. The mean operative time was calculated 169.9 ± 11.1 minutes. Conclusion: Pull-through transection procedure using the TA-90 non-cutting stapler is a safe, efficient and economically sound technique implicated in low-lying rectal lesions. The transanal 'Pull-through' approach is particularly helpful in situations where the direct visualization of lower rectal mucosa changes the prognosis through determining the marginal extent of intact/involved mucosa (e.g., FAP, villous adenomas, rectal polyps and post-neoadjuvant chemoradiotherapy tumors).

Experiência e objetivos: Descrever uma inovação técnica prática (abordagem transanal pull-through) como uma alternativa viável, segura e eficaz à anastomose transabdominal retal baixa convencional com grampos em lesões com mínima diferenciação anatômica com respeito à mucosa intacta adjacente. Material e métodos: Estudo prospectivo de série de casos de pacientes com cânceres retais baixos, polipose adenomatosa familiar e colite ulcerativa submetidos à transecção pull-through e a uma anastomose retal muito baixa com o uso de um grampeador linear não cortante TA-90 e um grampeador cortante circular. Resultados: Nesta série, 20 pacientes (11 homens, 9 mulheres) foram submetidos a uma proctectomia pela técnica transanal pull-through. À exceção de um dos pacientes, que apresentou um abcesso pélvico no seguimento pós-operatório imediato, não ocorreram complicações com o procedimento cirúrgico e ao longo do prolongado período de seguimento, nem houve achados críticos de vazamento, estenose ou sangramento. O percentual de infecção e incontinência fecal no pós-operatório não foi significativamente diferente entre gêneros e nas diferentes faixas etárias dos pacientes envolvidos no estudo. O tempo cirúrgico médio foi de 169,9 ± 11,1 minutos. Conclusão: O procedimento de transecção pull-through com o uso do grampeador não cortante TA-90 é técnica segura, eficaz e economicamente confiável para uso em lesões retais baixas. A abordagem transanal pull-through tem particular utilidade em situações nas quais a visualização direta de alterações na mucosa retal mais baixa muda o prognóstico, mediante a determinação da extensão marginal da mucosa intacta/envolvida (p. ex., FAP, adenomas vilosos, pólipos retais e tumores pós-quimiorradioterapia neoadjuvante).

Efficacy and safety of a NiTi CAR 27 compression ring for end-to-end anastomosis compared with conventional staplers: A real-world analysis in Chinese colorectal cancer patients

OBJECTIVES: This study aimed to evaluate the safety and efficacy of a new nickel-titanium shape memory alloy compression anastomosis ring, NiTi CAR 27, in constructing an anastomosis for colorectal cancer resection compared with conventional staples. METHODS: In total, 234 consecutive patients diagnosed with colorectal cancer receiving sigmoidectomy and anterior resection for end-to-end anastomosis from May 2010 to June 2012 were retrospectively analyzed. The postoperative clinical parameters, postoperative complications and 3-year overall survival in 77 patients using a NiTi CAR 27 compression ring (CAR group) and 157 patients with conventional circular staplers (STA group) were compared. RESULTS: There were no statistically significant differences between the patients in the two groups in terms of general demographics and tumor features. A clinically apparent anastomotic leak occurred in 2 patients (2.6%) in the CAR group and in 5 patients (3.2%) in the STA group (p=0.804). These eight patients received a temporary diverting ileostomy. One patient (1.3%) in the CAR group was diagnosed with anastomotic stricture through an electronic colonoscopy after 3 months postoperatively. The incidence of postoperative intestinal obstruction was comparable between the two groups (p=0.192). With a median follow-up duration of 39.6 months, the 3-year overall survival rate was 83.1% in the CAR group and 89.0% in the STA group (p=0.152). CONCLUSIONS: NiTi CAR 27 is safe and effective for colorectal end-to-end anastomosis. Its use is equivalent to that of the conventional circular staplers. This study suggests that NiTi CAR 27 may be a beneficial alternative in colorectal anastomosis in Chinese colorectal cancer patients.

Adult male circumcision with a circular stapler versus conventional circumcision: A prospective randomized clinical trial

Male circumcision is the most frequently performed procedure by urologists. Safety and efficacy of the circumcision procedure requires continual improvement. In the present study, we investigated the safety and efficacy of a new male circumcision technique involving the use of a circular stapler. In total, 879 consecutive adult male patients were randomly divided into 2 groups: 441 underwent stapler circumcision, and 438 underwent conventional circumcision. The operative time, pain score, blood loss volume, healing time, treatment costs, and postoperative complications were compared between the two groups. The operative time and blood loss volume were significantly lower in the stapler group than in the conventional group (6.8 ± 3.1 vs 24.2 ± 3.2 min and 1.8 ± 1.8 vs 9.4 ± 1.5 mL, respectively; P<0.01 for both). The intraoperative and postoperative pain scores were significantly lower in the stapler group than in the conventional group (0.8 ± 0.5 vs 2.4 ± 0.8 and 4.0 ±0.9 vs 5.8 ± 1.0, respectively; P<0.01 for both). Additionally, the stapler group had significantly fewer complications than the conventional group (2.7% vs 7.8%, respectively; P<0.01). However, the treatment costs in the stapler group were much higher than those in the conventional group (US$356.60 ± 8.20 vs US$126.50 ± 7.00, respectively; P<0.01). Most patients (388/441, 88.0%) who underwent stapler circumcision required removal of residual staple nails. Overall, the present study has shown that stapler circumcision is a time-efficient and safe male circumcision technique, although it requires further improvement.

Modified single stapler technique in anterior resection for rectal cancer

Technical difficulties during colorectal surgery increase the complication rates. We introduce a modified single stapler technique for patients in whom technical problems are encountered while performing double stapler technique. Before pelvic dissection, descending colon is divided at minimum 10 cm proximal to the tumoral segment. Tumor specific mesorectal excision is performed and two purse string sutures are placed at the distal margin with an interval of 1 - 2 cm. After introducing a circular stapler via the anus, the distal purse string suture is tied around the central shaft of the stapler and the proximal purse string suture around the colonic lumen. After the resection is completed between the two sutures, the anvil shaft is connected to the central shaft and the stapler is closed and fired. None of the patients had an anastomotic leak. This technique may be a safe alternative particularly in patients with narrow pelvis and distal tumors

Clinical effect of circumcision stapler in the treatment of phimosis and redundant prepuce / 中华男科学杂志

<p><b>OBJECTIVE</b>To observe the clinical effect and safety of circumcision stapler in the treatment of phimosis and redundant prepuce.</p><p><b>METHODS</b>We treated 120 patients with redundant prepuce or phimosis using circumcision stapler and another 60 by conventional dorsal-incision circumcision. We observed intraoperative blood loss, operation time, postoperative pain, wound healing time, cosmetic appearance of the penis, and postoperative complications and compared them between the two groups of patients.</p><p><b>RESULTS</b>Stapler circumcision showed obvious advantages over the conventional method in intraoperative blood loss ([2. 3 ± 1. 3] vs [15.6 ± 2.9] ml), operation time ([7.1 ± 1.4] vs [22.6 ± 4.6] min), wound healing time ([12.0 ± 2.9] as [16.3 ± 3. 1] d), postoperative pain score (1. 9 ± 1. 3 vs 5. 2 ± 1. 7), incision edema, and cosmetic appearance of the penis (all P <0. 05). Besides, stapler circumcision exempted the patients from stitch-removal pain. However, the incidence rate of postoperative local ecchymosis was significantly higher in the circumcision stapler group than in the conventional circumcision group (20. 8% vs 8. 3% , P <0. 05).</p><p><b>CONCLUSION</b>Circumcision stapler, with its advantages of easier manipulation, shorter operation time, better cosmetic penile appearance, less pain, and fewer complications, is superior to conventional circumcision in the treatment of phimosis and redundant prepuce.</p>

A modified method using a two-port approach for accessing the hilar vasculature without transferring an endostapler from camera port to utility port during thoracoscopic right upper lobectomy.

For thoracoscopic upper lobectomies, most cutting endostaplers must be inserted through the camera port when using a two-port approach. Access to the hilar vasculature through only the utility port remains a challenge. In this study, we describe a procedure to access the hilar vasculature without transferring the endostapler site during a thoracoscopic right upper lobectomy. A 2.5-cm utility anterior incision was made in the fourth intercostal space. The posterior mediastinal visceral pleura were dissected to expose the posterior portion of the right upper bronchus and the anterior trunk of the right pulmonary artery. The pleura over the right hilar vasculature were then peeled with an electrocoagulation hook. The anterior trunk of the right pulmonary artery was then transected with a cutting endostapler through the utility port firstly. This crucial maneuver allowed the endostapler access to the right upper lobe pulmonary vein. The hilar structures were then easily handled in turn. This novel technique was performed successfully in 32 patients, with no perioperative deaths. The average operation time was 120.6 min (range 75–180 min). This novel technique permits effective control of the hilar vessels through the utility port, enabling simple, safe, quick and effective resection.

Effectiveness of procedure for prolapse and hemorrhoids in immediate postoperative period

To document the early outcome of stapled hemorrhoidopexy, the procedure for prolapsed and hemorrhoids [PPH]. Descriptive case series. Rehman Medical Institute [RMI], Peshawar; from May 2012 to May 2013. A total of 24 patients requiring surgical treatment for prolapsing hemorrhoids of degree II and III were included in the study. Outcome measures were postoperative pain, bleeding, sepsis, urinary retention, relief of preoperative symptoms, operation time and length of hospital stay. Mean age of patients was 46.8 year. All surgeries were performed under spinal anesthesia. Mean surgical time was 22.5 minutes. The average distance between the stapling line and the dentate line was 2.6 cm. Postoperative pain at rest and during defecation was mild to moderate after PPH. Healing time was shorter after PPH and no patient had perioperative or postoperative bleeding. Postoperative pain was mild to moderate in majority of patients. There were no intraoperative or postoperative complications. PPH was a safe procedure and resulted in swift recovery and earlier return to work

Then we compared the safety and efficiency of the two strategies.</p><p><b>RESULTS</b>Comparisons between DCSD and CC showed that the operation time was (4.02 +/- 0.69) vs (30.8 +/- 4.05) min, blood loss was (1.07 +/- 1.29) vs (8.72 +/- 2.15) ml, intraoperative pain score was 0.81 +/- 0.81 vs 2.42 +/- 1.15, 24-hour postoperative pain score was 1.84 +/- 1.02 vs 4.99 +/- 1.36, postoperative complication rate was 13. 95% (18/129) vs 9.17% (11/120), wound healing time was (13.99 +/- 9.06) vs (17.48 +/- 3.49) d, satisfaction with the penile appearance was 98.4% (127/129) vs 95% (109/120), and treatment cost was (2215.62 +/- 17.67) vs (576.47 + 15.58) Y RMB. DCSD exhibited obvious superiority over CC for shorter operation time, less blood loss, milder intraoperative pain, sooner wound healing, and better penile appearance, but it also had a higher rate of postoperative complications (P > 0.05) and involved more treatment cost than the latter (P < 0.05).</p><p><b>CONCLUSION</b>The disposable circumcision suture device affords ideal clinical effects and therefore deserves clinical popularization.</p>

Tratamento de hérnias da linha média do abdome com uso de grampeador endoscópico para fechamento da linha média / Treatment of mid-line abdominal wall hernias with the use of endo-stapler for mid-line closure

INTRODUÇÃO: A cirurgia minimamente invasiva modificou a maneira de analisar e dissecar os tecidos nos procedimentos cirúrgicos. No entanto, a vantagem deste método é limitada na parede abdominal, devido à falta de desenvolvimento de tecnologias e movimentos articulados para seu emprego nesta região, exigindo a necessidade de investimentos e de tempo para a solidificação. Esta abordagem para reparo operatório da parede abdominal é baseada nos princípios Rives-Stoppa. TÉCNICA: Com o paciente em decúbito dorsal, uma pequena incisão supra-púbica é feita e o espaço pré-peritoneal é alcançado e insuflado. Após os trocárteres serem colocados, o saco peritoneal é dissecado e a cavidade abdominal é atingida acima da linha arqueada. As bainhas posteriores do músculo reto do abdome são liberadas e um grampeador linear é colocado em ambos os lados e acionado, restituindo a linha média e criando um espaço retromuscular, onde a tela é colocada e fixada. CONCLUSÃO: O método é viável, fácil de realizar e reprodutível, economizando tempo e com resultado funcional satisfatório.

INTRODUCTION: Minimally invasive videosurgery has modified anatomy dissection of diseases that are treated operatively. However, the benefit of this method has been delayed due to the lack of development of technologies and articulated movements for the abdominal wall, demanding the need for investments and time for solidification. This approach to repair the abdominal wall is based on the Rives-Stoppa principles. TECHNIQUE: With the patient in supine position, a small supra pubic incision is done and the pre-peritoneal space is achieved and inflated. After the trocars are placed, the peritoneal sac is dissected and the abdominal cavity is entered, above the arcuate line. The posterior rectus sheath is liberated and a linear stapler is placed in both sides and fired, creating a midline and a retromuscular space, where the mesh is placed and fixed. CONCLUSION: The method is feasible, easy to perform, reproducible, saves time and with a good functional result.

Introdução: A ocorrência de fístulas faringocutâneas apóslaringectomias totais é um fator de grande impacto no tempode internação do doente enquanto a demora no fechamentoda faringe é significativa no tempo de permanência em salacirúrgica. Ambos afetam o custo final do procedimento cirúrgico.O uso da sutura mecânica pode reduzir estes tempos e,consequentemente, dos custos do procedimento. Objetivos:Comparar os custos resultantes do fechamento manual emecânico da faringe. Método: estudo retrospectivo, avaliandoo tempo de permanência em sala cirúrgica e permanênciahospitalar de pacientes submetidos a laringectomia total, quantoaos dois tipos de fechamento da faringe: Manual ou mecânico.Resultados: A fístulas faringocutâneas ocorreram apenas noscasos de fechamento manual (17,3%), resultando em uma maiorpermanência hospitalar neste grupo (12,23 x 6,5 dias da suturamecânica). O tempo operatório também foi maior naquele grupo(2h20min maior). A média dos custos do fechamento manual foramR$5.799,24. Isto supera o custo do grampeador, de R$ 1033,00.Conclusão: O fechamento da faringe com grampeador deve serpreferido, sempre que possível, pois apresenta menores índicesde complicações e custos menores, apesar do preço do mesmo.

Choice and reasonable application of staplers for gastrointestinal surgery / 中华胃肠外科杂志

Digestive tract reconstruction is the main part of gastrointestinal surgery. With the rapid development of technology and widely application in stapling device, more and more surgeons are using stapled anastomosis. Stapled anastomosis is associated with shorter operating time and hospital stay than hand-sewn anastomosis. However, it is not easy to select suitable ones from various staplers and use them correctly. Choice and reasonable application of staplers for anastomosis in gastrointestinal surgery are summarized and evaluated in this article.

Utilidad de los dispositivos de sutura mecánica circular para técnicas endoanales / Circular staplers devices in endoanal techniques

INTRODUCCION: entre las técnicas descriptas para corregir defectos del piso pelviano, el uso de suturas mecánicas circulares se plantea como una opción con fundamentos anatómicos y funcionales, con bajos índices de complicaciones. OBJETIVO: analizar las indicaciones y técnicas utilizando suturas mecánicas circulares por vía Endoanal, su factibilidad y resultados inmediatos. DISEÑO: estudio prospectivo, consecutivo, no randomizado. MATERIAL Y METODO: entre Junio de 2007 y Diciembre de 2010 se utilizaron los dispositivos PPH 03 y PPH 01 en 62 pacientes. Se analizan: indicaciones, técnica, tiempo operatorio, morbilidad, internación y resultados funcionales inmediatos. RESULTADOS: con el procedimiento PPH fueron intervenidos 40 pacientes. Con la técnica STARR fueron operadas 22 mujeres. Para el procedimiento PPH el tiempo operatorio promedio fue de 30 minutos y la morbilidad 15%. Para STARR el tiempo operatorio promedio fue de 40 minutos y la morbilidad 4,5%. Con la técnica PPH se obtuvo 100% de corrección de prolapso. Con STARR se observó disminución del ODS Score en todos los casos. Internación promedio: 1 día. CONCLUSIONES: el uso de los dispositivos de sutura mecánica circular por vía endoanal es factible y seguro. Utilizados por coloproctólogos con experiencia ofrecen una alternativa válida en los pacientes que cumplan los requisitos para indicarlos.

BACKGROUND: several techniques have been described for the treatment of pelvic floor diseases. The circular stapler devices are advocated as a safety and effectiveness option, with anatomical and physiological basis. OBJECTIVE: The aim of this study was to demonstrate the feasibility, effectiveness and reliability of the circular staplers devices for endoanal techniques. DESIGN: non-randomized, prospective study. MATERIAL AND METHODS: since June 2007 up to December 2010 we have applied the PPH 03 and PPH 01 devices to 60 patients. We analyzed indications, surgical techniques mean operative time, complications, mean length of stay and immediate functional results. RESULTS: we have applied the PPH procedure to 40 patients and the STARR procedure to 22 female patients. To PPH procedure the mean duration of the operation was 30 minutes and we registered a rate of complications to 15%. To STARR procedure the mean operative time was 40 minutes and the morbidity was 4,5%. Mean length of stay was 1 day. CONCLUSIONS: the circular stapler devices trough endoanal techniques are feasible, safe and effective with low morbidity. Colorectal surgeons might implement them in the use of them in order to optimize results. Further investigation is required to optimize patient selection and reduce potential complications.

Comparison of standard 4-row versus 6-row3-D linear cutter stapler in creation of gastrointestinal system anastomoses: a prospective randomized trial

OBJECTIVE: This prospective study was conducted to compare the clinical outcomes of a 6-row 3-D linear cutter with the standard 4-row linear cutter in patients who underwent elective gastrointestinal surgery anastomosis. METHOD: Patients who underwent elective open gastrointestinal surgery that included stapled anastomosis using a linear cutter (Proximate®, Ethicon Endo-Surgery, Cincinnati, OH) between January 2011 and May 2011 were included in the study. The patients were randomly assigned to two groups according to the linear cutter that was used in the surgery: the standard 4-row cutter (the S group) or the new 6-row cutter (the N group). The groups were compared based on the patient demographic data, the laboratory parameters, the preoperative diagnosis, the surgery performed, the operation time, intra-or postoperative complications, the time to oral tolerance and the length of the hospital stay. RESULTS: The S group included 11 male and nine female patients with a mean age of 65 ± 12 (35-84) years, while the N group included 13 male and eight female patients with a mean age of 62 ±11 (46-79) years (p =0.448, p = 0.443, respectively). Anastomotic line bleeding was observed in eight (40%) patients in the S group and in one (4.7%) patient in the N group (p = 0.006). Dehiscence of the anastomosis line was observed in two (10%) patients in the S group and none in the N group (p =0.131). Anastomotic leakage developed in three (15%) patients in the S group and in one (4.7%) patient in the N group (p = 0.269). The mean hospital stay was 12.65 ± 6.1 days in theS group and 9.52 ± 2.9 days in the N group (p = 0.043). CONCLUSION: The 6-row 3-D linear cutter is a safe and easily applied instrument that can be used to create anastomoses in gastrointestinal surgery. The new stapler provides some usage benefits and is also superior to the standard linear cutter with regard to anastomotic line bleeding.
