RESUMO
OBJECTIVE: Zenker diverticulum (ZD), a pulsion diverticulum of the esophagus, has been traditionally managed with an open surgical approach, but endoscopic transoral stapling has been reported with increasing frequency. The objective of this study was to evaluate the results of endoscopic repair of ZD by a thoracic surgery service. METHODS: We conducted a retrospective review of patients who underwent transoral stapling repair of ZD at our institution by the thoracic surgery service. We evaluated perioperative outcomes including dysphagia (1, no dysphagia to 5, unable to swallow saliva) and failure of repair requiring surgical intervention. RESULTS: A total of 151 patients (median age, 78 years; 75 men, 76 women) underwent evaluation for endoscopic repair of ZD. Endoscopic stapled repair of the ZD was completed in 135. Sixteen patients underwent conversion to open repair. The perioperative mortality was 0.6% (1 patient). The median hospital stay was 2 days (range, 0-18 days). Complications occurred in 5 patients who underwent endoscopic repair. The mean preoperative dysphagia score was 2.8 and improved to 1.2 during follow-up (median, 16 months; P < .001). During further follow-up (median, 52 months), 8 patients (5.3%) had failure of the endoscopic repair requiring open surgery (n = 5) or redo transoral stapling (n = 3). CONCLUSIONS: Endoscopic stapling repair of ZD can be performed safely with good results in experienced centers by thoracic surgeons with significant esophageal experience. Long-term follow-up is required to evaluate the durability of endoscopic repair of ZD.

Aneurysmal degeneration following long-term access is an important problem associated with an arteriovenous fistula (AVF) and can result in rupture, thrombosis, or the need for ligation. We describe five patients receiving hemodialysis through large degenerative brachiocephalic AVFs who underwent successful revision and avoided the need for a temporary dialysis catheter. A hybrid approach using an open surgical technique with both endovascular and laparoscopic tools provides an opportunity to maintain patency and restore function by combining modern surgical tools.

PURPOSE: To evaluate the effect of fibrin glue on staple-line leak after sleeve gastrectomy. METHODS: Fourteen adult wistar rats 300 gr were randomized into two groups: Control group (n=7) and study group (n=7). All the rats underwent sleeve gastrectomy using lineer stapler. In the study group, fibrin glue was used to reinforce the staple-line. The rats were sacrificed 7 days after surgery. The stomach was resected, submerged in saline and exposed to excess pressure to obtain a burst pressure value. The gastric staple line was evaluated histopathologically according to the Ehrlich Hunt scale. The results of the two groups were compared. RESULTS: The mean Ehrlich-Hunt scores for inflammation, fibroblastic activity and neo-angiogenesis were similar between the groups (p>0.05). Collagen deposition was significantly higher in study group (3.42±0.53) when compared with control group (2.57±0.78) (p=0.035). The mean burst pressure was 137.8±8.5 mmHg for control group and 135.0±8.1 mmHg for study group (p=0.536). CONCLUSION: Reinforcement of the staple-line with fibrin glue has no effect on the burst pressure after sleeve gastrectomy. More studies are needed to evaluate the precautions against leak after sleeve gastrectomy.

ABSTRACT Study objective: The aim is to assess the presence and persistence of the agraphes at the level of staple line after transanal stapled surgery. Methods: From April to December 2016 one-hundred-thirteen patients with variable follow-up (6 months-10 years) were randomly selected among all the patients undergone transanal stapled surgery for haemorrhoidal disease or functional disorders such as obstructed defecation syndrome. Only 87 patients agreed to participate this study. All the patients underwent digital exploration, anoscopy and 360° tridimensional transanal ultrasound. Main results: Different types of stapled transanal surgical procedures were performed: 48 transanal rectal resection with high volume device, 24 stapled haemorrhoidopexy, 8 Double Stapled Haemorrhoidopexy, 7 Transtarr. In 41.4% the staple line was not identified with digital examination or anoscopy and 17.2% of patients have some staples partially expelled inside the lumen. 360° tridimensional transanal ultrasound showed a complete staple line at the ano-rectal junction which appears as an interrupted hyperechoic circular layer. Conclusion: The staples after stapled transanal surgery remain at the level of the staple line independently from the device used by the surgeon leading to the necessity of a shared and adequate language, in fact the shed staples need to be considered as expelled instead of retained.
RESUMO Objetivo do estudo: Avaliar a presença e persistência dos agrafes ao nível da linha de aplicação dos grampos, em seguida à cirurgia transanal com grampeador. Métodos: De abril até dezembro de 2016, 113 pacientes com seguimentos variáveis (6 meses-10 anos) foram aleatoriamente selecionados entre todos os pacientes tratados com cirurgia transanal com grampos para tratamento de hemorroidas ou de transtornos funcionais, por exemplo, síndrome de evacuação obstruída. Apenas 87 pacientes concordaram em participar do estudo. Todos os pacientes passaram por exploração digital, anoscopia e ultrassonografia transanal tridimensional de 360°. Resultados principais: Foram realizados diferentes tipos de procedimentos cirúrgicos transanais com grampeador: 48 ressecções retais transanais com uso de grampeador de grande volume, 24 hemorroidopexias com grampeador, 8 hemorroidopexias com grampos duplos e 7 procedimentos com grampeador Transtar. Em 41,4% dos tratamentos, não foi possível identificar a linha de grampeamento com exame digital ou com anoscopia, e em 17,2% dos pacientes alguns grampos foram expelidos para o lúmen. A ultrassonografia transanal tridimensional de 360° revelou uma linha de grampeamento completo na junção anorretal, assumindo o aspecto de uma camada circular hiperecoica interrompida. Conclusão: Em seguida à cirurgia transanal com grampeamento, os grampos permanecem ao nível da linha de grampeamento, independentemente do tipo de grampeador usado pelo cirurgião, o que torna necessária uma linguagem compartilhada e adequada; de fato, os grampos soltos devem ser considerados como expelidos, em lugar de retidos.

INTRODUCTION: Repair of inguinal hernia is one of the most common elective operations performed in general surgery practice. Mesh hernia repair became the gold standard because of its low recurrence rate in comparison with non-tension-free repair. Laparoscopic approach seems to have potential advantages over open techniques, including faster recovery and reduced acute and chronic pain rate. Laparoscopic mesh fixation is usually performed using staples, which is associated with higher cost and risk for chronic pain. Recently, the role of mesh fixation has been questioned by several surgeons. AIM: To evaluate mesh displacement in patients undergoing laparoscopic inguinal hernia repair comparing mesh fixation with no fixation. METHODS: From January 2012 to May 2014, 60 consecutive patients with unilateral inguinal hernia were randomized into two groups: control group--10 patients underwent totally extraperitoneal (TEP) repair with mesh fixation; NO FIX group-50 patients underwent TEP repair with no mesh fixation. Mesh was marked with three 3-mm surgical clips at its medial inferior, medial superior and lateral inferior corners. Mesh displacement was measured by comparing an initial X-ray, performed in the immediate postoperative period, with a second X-ray obtained 30 days later. RESULTS: The mean displacement of all three clips in control group was 0.1-0.35 cm (range 0-1.2 cm), while in NO FIX group was 0.1-0.3 cm (range 0-1.3 cm). The overall displacement of control and NO FIX group did not show any difference (p = 0.50). CONCLUSION: Fixation of the mesh for TEP repair is unnecessary. TEP repair with no mesh fixation is safe and is not associated with increased risk of mesh displacement.

BACKGROUND: The procedure for prolapsing hemorrhoids (PPH) has the potential to overcome many of the disadvantages of excisional hemorrhoidectomy; nevertheless, rare serious postoperative complications have been reported. CLINICAL CASE: We present a case of a 31-year-old male who was admitted and treated at another hospital with a stapled mucosectomy, which was carried out using a PPH01 33-mm stapling device. During the immediate postoperative period a fistula presented from the rectum to the right gluteus and a primary closure was attempted. However, the patient continued with the same symptoms and was referred to our hospital in October 2009. On examination at our Department of Colorectal Surgery, a right gluteus abscess was found and a primary orifice in the rectum with a diameter of 10 mm at 4 cm from the anal verge, confirmed with magnetic resonance imaging. A primary closure was attempted; however, during follow-up the patient presented edema, erythema and induration of the right gluteus and a failed closure of the fistula. Afterwards an endorectal advancement flap was successful in the closure of the fistula. CONCLUSIONS: Complications with PPH may compromise function or may be life-threatening for the patient, requiring further surgeries with increased morbidity and mortality. Therefore, it is recommended to be performed by surgeons with special training in this procedure.

Objetivo: Comparar el resultado clínico de la mucosectomía rectal con engrapadora (MRE) sola y de la MRE combinada con esfinterotomía y con plastia anal de colgajos cutáneos, y examinar qué factores influyen sobre las complicaciones y la satisfacción del paciente. Material y métodos: Se incluyeron pacientes con enfermedad hemorroidal grados II a IV sometidos a MRE sola o en combinación con otros procedimientos. Se analizaron las complicaciones posoperatorias, resolución de síntomas y grado de satisfacción. Resultados: 241 pacientes consecutivos con seguimiento mínimo de un año se dividieron en tres grupos: MRE sola (n = 187), MRE combinada con esfinterotomía (n = 31) y MRE combinada con plastia de colgajos (n = 23). Los pacientes con MRE con esfinterotomía presentaron un porcentaje de complicaciones mayor que el resto (32 versus 12.8 % y 13 %, respectivamente, p = 0.02). La MRE con esfinterotomía se asoció con mayor riesgo de complicaciones que la MRE sola (RM = 3.5, IC 95 % = 1.4-8.7); la inclusión exclusiva de epitelio columnar en la zona resecada se asoció con menor riesgo de complicaciones que cuando se incluyó además epitelio transicional (RM = 0.4, IC 95 % = 0.2-0.8). La resolución de síntomas preoperatorios en la mayor parte de los pacientes fue > 80 % en los tres grupos. No hubo asociación de complicaciones o del tipo de procedimiento con el grado de satisfacción. Cuando el porcentaje de síntomas resueltos fue < 80 % se asoció con grado bajo o intermedio de satisfacción (p < 0.001). Conclusiones: La resolución de los síntomas preoperatorios con los tres procedimientos es similar. La MRE con esfinterotomía tiene mayor riesgo de complicaciones. El grado de satisfacción se asocia con la resolución de los síntomas preoperatorios.
BACKGROUND: We undertook this study to compare the clinical outcome of stapled rectal mucosectomy (SRM) alone and in combination with sphincterotomy and cutaneous flap anoplasty and to determine the influence of factors related to complications and patient satisfaction. METHODS: Patients with second- to fourth-degree hemorrhoids who underwent SRM alone or in combination with other anorectal procedures were included. Postoperative complications, symptom resolution and patient satisfaction were analyzed. RESULTS: Two hundred forty one patients with a minimum follow-up of 1 year were divided into three groups: SRM alone (n = 187), SRM combined with sphincterotomy (n = 31) and SRM combined with cutaneous flap anoplasty (n = 23). Patients with SRM with sphincterotomy showed a higher complication rate than the other groups (32 vs. 12.8% and 13%, respectively, p = 0.02). SRM combined with sphincterotomy was associated with a higher rate of complications (OR = 3.5; 95% CI = 1.4-8.7). SRM alone with low mucosal resection was associated with a lower complications rate (OR = 0.4, 95% CI = 0.2-0.8). Resolution of preoperative symptoms was >80% among the three groups. There was no association between complications and type of procedure with satisfaction level. Resolution of symptoms <80% was associated with low/intermediate level of satisfaction (p <0.001). CONCLUSIONS: Resolution of preoperative symptoms is similar among the three groups. SRM combined with sphincterotomy has a higher risk of complications. The satisfaction level is associated with resolution of preoperative symptoms.

Rectal bleeding following colorectal anastomosis is common but usually self-limited. Continuous hemorrhage is rare, and when it occurs, often requires further treatment. The most frequently used strategies for treatment of stapled anastomotic hemorrhage are clinical observation with or without blood transfusion, rectal packing, angiographic identification of the bleeding site with vasopressin infusion or embolization, and endoscopic eletrocoagulation. We report the case of a 49-year-old man with uncomplicated diverticular disease who was treated by laparoscopic sigmoidectomy, with double-stapled colorectal anastomosis. Six hours later, the patient presented intense rectal bleeding and was taken to the operation room for urgent colonoscopic examination. After complete removal of blood clots inside the rectum, a bleed localized at the anastomotic site was identified and submucosal peri-anastomotic injection of 10 ml adrenaline (1:200 000) in saline was performed with immediate bleeding control.
