Comparing three-dimensional endorectal ultrasound and magnification chromoendoscopy for early rectal neoplasia invasion depth assessment.

INTRODUCTION: Accurate assessment of invasion depth of early rectal neoplasms is essential for optimal therapy. We aimed to compare three-dimensional endorectal ultrasound (3D-ERUS) with magnification chromoendoscopy (MCE) regarding their accuracy in assessing parietal invasion depth (T). METHODS: Patients with middle and distal rectum neoplasms were prospectively included. Two providers blinded to each other's assessment performed 3D-ERUS and MCE, respectively. The T stage assessed through ERUS was compared to the MCE evaluation. The results were compared to the surgical specimen anatomopathological report. Sensitivity, specificity, accuracy, positive (PPV), and negative (NPV) predictive values were calculated for the T stage and for the final therapy (local excision or radical surgery). RESULTS: In 8 years, 70 patients were enrolled, and all underwent both exams. MCE and ERUS showed an accuracy of 94.3% and 85.7%, sensitivity of 83.7 and 93.3%, specificity of 96.4 and 83.6%, PPV of 86.7 and 60.9%, and NPV of 96.4 and 97.9%, respectively. Kappa for T stage assessed through ERUS was 0.64 and 0.83 for MCE. CONCLUSION: MCE and 3D-ERUS had good diagnostic performance, but the endoscopic method had higher accuracy. Both methods reliably assessed lesion extension, circumferential involvement, and distance from the anal verge.

Combined Robotic Ventral Mesh Rectopexy and Sacrocolpopexy for Multicompartmental Pelvic Organ Prolapse.

BACKGROUND: Multispecialty management should be the preferred approach for the treatment of pelvic floor dysfunction because there is often multicompartmental prolapse. OBJECTIVE: To assess the safety of combined robotic ventral mesh rectopexy and either uterine or vaginal fixation for the treatment of multicompartmental pelvic organ prolapse at our institution. DESIGN: Retrospective analysis. SETTINGS: Tertiary referral academic center. PATIENTS: All patients who underwent a robotic approach and combined procedure and whose cases were discussed at a biweekly pelvic floor multidisciplinary team meeting. MAIN OUTCOME MEASURES: Operative time, intraoperative blood loss and complications, postoperative pelvic organ prolapse quantification score, length of stay, 30-day morbidity, and readmission. RESULTS: From 2018 to 2021, there were 321 operations for patients with multicompartmental prolapse. The mean age was 63.4 years. The predominant pelvic floor dysfunction was rectal prolapse in 170 cases (60%). Pelvic organ prolapse quantification scores were II in 146 patients (53%), III in 121 patients (44%), and IV in 9 patients (3%); 315 of 323 cases included robotic ventral mesh rectopexy (98%). Sacrocolpopexy or sacrohysteropexy was performed in 281 patients (89%). Other procedures included 175 hysterectomies (54%), 104 oophorectomies (32%), 151 sling procedures (47%), 149 posterior repairs (46%), and 138 cystocele repairs (43%). The operative time for ventral mesh rectopexy was 211 minutes and for combined pelvic floor reconstruction was 266 minutes. Average length of stay was 1.6 days. Eight patients were readmitted within 30 days: 1 with a severe headache and 7 with postoperative complications (2.5%), such as pelvic collection and perirectal collection, both requiring radiologic drainage. Four complications required reoperation: epidural abscess, small-bowel obstruction, missed enterotomy requiring resection, and urinary retention requiring sling revision. There were no mortalities. LIMITATIONS: Retrospective single-center study. CONCLUSIONS: A combined robotic approach for multicompartmental pelvic organ prolapse is a safe and viable procedure with a relatively low rate of morbidity and no mortality. This is the highest volume series of combined robotic pelvic floor reconstruction in the literature and demonstrates a low complication rate and short length of stay. See Video Abstract .

La edad media fue 63.4 años. La disfunción del suelo pélvico predominante fue el prolapso rectal en 170 casos (60%). Las puntuaciones de cuantificación del prolapso de órganos pélvicos fueron II en 146 pacientes (53%), III en 121 (44%) y IV en 9 (3%); 315 de los 323 casos incluyeron rectopexia robótica de malla ventral (98%). Se realizó sacrocolpopexia o sacrohisteropexia en 281 pacientes (89%). Otros procedimientos incluyeron 175 histerectomías (54%), 104 ooforectomías (32%), 151 procedimientos de cabestrillo (47%), 149 reparaciones posteriores (46%) y 138 reparaciones de cistocele (43%). El tiempo operatorio para la rectopexia con malla ventral fue de 211 minutos y la reconstrucción combinada del piso pélvico de 266 minutos. La estancia media fue de 1.6 días. Ocho pacientes reingresaron dentro de los 30 días, 1 con dolor de cabeza intenso y 7 pacientes con complicaciones posoperatorias (2.5%): colección pélvica y colección perirrectal, ambas requirieron drenaje radiológico. Cuatro complicaciones requirieron reoperación: absceso epidural, obstrucción del intestino delgado, enterotomía omitida que requirió resección y retención urinaria que requirió revisión del cabestrillo. No hubo mortalidades.LIMITACIONES:Estudio retrospectivo unicéntrico.CONCLUSIONES:Un enfoque robótico combinado para el prolapso multicompartimental de órganos pélvicos es un procedimiento seguro y viable con una tasa relativamente baja de morbilidad y ninguna mortalidad. Esta es la serie de mayor volumen de reconstrucción robótica combinada del suelo pélvico en la literatura y demuestra una baja tasa de complicaciones y una estancia hospitalaria corta.

A Head-to-Head Comparison of Computed Tomography Colonography, Optical Colonoscopy, and Colon Endoscopic Capsule for the Detection of Polyps After Partial Colectomy or Rectosigmoidectomy for Colorectal Cancer: A Pilot Study.

Background and objective Optical colonoscopy is the gold standard method for the diagnosis of colorectal cancer (CRC) and it allows for biopsy and resection, as well as documentation of synchronous lesions. CT colonography (CTC) and colon endoscopic capsule (CEC) are also recommended as alternative minimally invasive or non-invasive procedures. Prospective studies comparing these three approaches are scarce in the current literature. In light of this, the aim of this pilot study was to compare the efficacy of polyp detection between these three methods in patients with a history of curative surgical resection of CRC. Methods Patients were consecutively recruited and all procedures were sequentially conducted on the same day. The primary endpoint was the detection rate of polyps, whereas secondary endpoints were the detection of polyps according to size and location, and the adverse events caused by these procedures. Results A total of 21 patients were consecutively included and all of them underwent all three interventions. No adverse events, local recurrences, or metachronous lesions were detected. In two cases with elevated carcinoembryonic antigen (CEA), CTC unveiled distant metastasis. Optical colonoscopy registered a mean of 0.4 polyp >6 mm and 1.3 polyps <6 mm per patient. CTC unveiled only 0.5 polyp >6 mm/patient and no smaller lesions were documented, whereas findings for the colon capsule comprised an average of 0.4 polyps >6 mm and 0.7 polyps <6 mm per patient. Statistical difference was not demonstrated, except for virtual colonoscopy in terms of the total number of polyps detected in comparison to optical colonoscopy. Conclusions Optical colonoscopy showed superior results in comparison to virtual colonoscopy while there was no statistical difference in comparison to colon capsule. Notwithstanding occasional difficulties, all three techniques were well tolerated. Hence, decisions concerning the use of each diagnostic method should be based on their availability, professional expertise, contraindications, and patient preferences.

Large rectal diverticulum in the setting of pelvic organ prolapse treated with robotic ventral mesh rectopexy: a case report.

Background: Rectal diverticula are a very rare occurrence compared to diverticula of the colon. They are reported to account for only 0.08% of all diverticulosis. Diverticula of the rectum can be caused by congenital or acquired factors. The majority are asymptomatic, diagnosed incidentally, and require no treatment. The low incidence of rectal diverticulosis may be attributed to the unique anatomical structure and physiological environment of the rectum. However, complications can arise and may necessitate surgical or endoscopic treatment. Case Description: We report the case of a 72-year-old female with a history of diabetes mellitus, hyperlipidemia, and hypothyroidism who presented to the colorectal surgery clinic with symptoms of constipation of nearly a 50-year duration. The patient underwent an anorectal exam under anesthesia which revealed a 3 cm defect in the left levator muscles with herniated rectal wall. A large left lateral rectal diverticulum was diagnosed during the work-up for pelvic organ prolapse on defecography. She underwent robotic assisted ventral mesh rectopexy and recovered uneventfully. After 1 year of follow-up, the patient is asymptomatic, and the control colonoscopy shows no signs of the rectal diverticulum. Conclusions: Rectal diverticula can present in the setting of pelvic organ prolapse and can be safely managed with ventral mesh rectopexy.

Unusual presentation of a neuroendocrine tumor in the ileostomy specimen after rectal cancer treatment: a case report.

Background: Neuroendocrine tumors of the small intestine are uncommon, but at the same time they are the most frequent subtype of neuroendocrine tumor in the gastrointestinal system. They originate from enterochromaffin cells, which are involved in the creation of serotonin. This asymptomatic characteristic in the initial presentation is usually why these tumors are discovered at a late stage, sometimes in association with symptomatic metastatic disease. Case Description: We present a case-report of a 52-year-old gentleman with a suggestive family history of hereditary cancer syndrome (mother with lung cancer and maternal uncle with colon cancer at the age of 40 years old). The patient was diagnosed with rectal cancer and he received neoadjuvant chemotherapy with short-course radiotherapy followed by a robotic low anterior resection with diverting loop ileostomy. Following closure of his ileostomy, the pathology report of the ileostomy resection specimen showed a 1.1 cm neuroendocrine tumor with negative margins. Conclusions: This extraordinary unusual presentation could be very fortuity for the patient, who in every other opportunity just found this neuroendocrine tumor after advanced or maybe metastatic diseases.

The double-barrel wet colostomy: An alternative for urinary diversion after pelvic exenteration.

AIM: Pelvic exenteration is a radical procedure used to treat locally advanced and/or recurrent pelvic malignancies. Different reconstruction options exist, the most popular being the end colostomy with ileal conduit. The double barrel wet colostomy (DBWC) offers concomitant fecal and urinary diversion through a single stoma, but is infrequently utilized. We aim to review the evidence base of the postoperative complications, long-term oncologic risks and quality of life following creation of a double barrel wet colostomy. METHODS: A narrative review of the literature was performed evaluating the DBWC. Patient demographics, perioperative complications, operative variables, long terms oncologic outcomes and quality of life data were extracted. Descriptive statistics were used to define the data. RESULTS: Fourteen articles with a total of 300 patients undergoing DBWC following pelvic exenteration were selected. 41% of malignancies were gastrointestinal in origin while 41.7% were gynecologic and 5.3% genitourinary. 42% of patients experienced at least one complication within in 40 days of surgery, the most common being wound infection (8.7%) and urinary leak (8.3%). There was no evidence of malignancy within the DBWC during long-term surveillance. Quality of life following DBWC is comparable to other reconstructive methods. CONCLUSION: The DBWC is a well described reconstructive method for urinary and fecal diversion utilizing a single stoma following pelvic exenteration. The short- and long-term outcomes following DBWC are comparable to other reconstructive methods and the quality of life with a DBWC is acceptable. DBWC should remain a readily available option for reconstruction following pelvic exenteration.

Intra-abdominal desmoid tumors in familial adenomatous polyposis: How much do clinical and surgical variables interfere with their development?

OBJECTIVE: Familial Adenomatous Polyposis is a complex hereditary disease that exposes the carrier to a great risk of Colorectal Cancer (CRC). After prophylactic surgery, intra-abdominal desmoid tumors are known to be one the most important cause of death. Therefore, recognition of increased-risk patients and modification of operative strategy may be crucial. AIM: The objective of this study was to estimate the desmoid tumor risk in relation to various surgical and clinical variables. METHODS: Patients who had undergone polyposis since 1958 were included in the study. After exclusion criteria were met, those who had developed desmoid tumors were selected to undergo further evaluation. RESULTS: The study revealed that the risk of developing desmoid tumors was associated with various factors such as sex ratio, colectomy, and reoperations. On the other hand, the type of surgery, family history, and surgical approach did not affect the risk of developing desmoid tumors. The data collected from 146 polyposis patients revealed that 16% had desmoid polyps. The sex ratio was 7:1, and the median age at colectomy was 28.6 years. Family history, multiple abdominal operations, and reoperations were some of the characteristics that were common in desmoid patients. CONCLUSION: Recognition of clinical (female sex) and surgical (timing of surgery and previous reoperations) data as unfavorable variables associated with greater risk may be useful during the decision-making process.

IS IT POSSIBLE TO OPTIMIZE STAPLED HEMORRHOIDOPEXY OUTCOMES BY ENLARGING OPERATIVE CRITERIA INDICATIONS? RESULTS OF A TAILORED PROCEDURE WITH ASSOCIATED RESECTION IN A COMPARATIVE PERSONAL SERIES.

BACKGROUND: Since its introduction, stapled hemorrhoidopexy has been increasingly indicated in the management of hemorrhoidal disease. AIM: Our primary end point was to evaluate the incidence of recurrent disease requiring another surgical intervention. On a secondary analysis, we also compared pain, complications, and patient's satisfaction after a tailored surgery. METHODS: We retrospectively reviewed 196 patients (103 males and 93 females) with a median age of 47.9 years (range, 17-78) who were undergoing stapled hemorrhoidopexy alone (STG; n=65) or combined surgery (CSG; n=131, stapled hemorrhoidopexy associated with resection). RESULTS: Complications were detected in 11 (5.6%) patients (4.6% for STG vs. 6.1% for CSG; p=0.95). At the same time, symptoms recurrence (13.8% vs. 8.4%; p=034), reoperation rate for complications (3.1% vs. 3.0%; p=1.0), and reoperation rate for recurrence (6.1% vs. 4.6%; p=1.0) were not different among groups. Grade IV patients were more commonly managed with simultaneous stapling and resection (63% vs. 49.5%), but none of them presented symptoms recurrence nor need reoperation due to recurrence. Median pain score during the first week was higher in CSG patients (0.8 vs. 1.7). After a follow-up of 24.9 months, satisfaction scores were similar (8.6; p=0.8). CONCLUSION: Recurrent symptoms were observed in 10% of patients, requiring surgery in approximately half of them. Even though the association of techniques may raise pain scores, a tailored approach based on amplified indication criteria and combined techniques seems to be an effective and safe alternative, with decreased relapse rates in patients suffering from more advanced hemorrhoidal disease. Satisfaction scores after hemorrhoidopexy are high.

Administration of an Anal Bulking Agent With Polyacrylate-Polyalcohol Copolymer Particles Versus Endoanal Electrical Stimulation With Biofeedback for the Management of Mild and Moderate Anal Incontinence: A Randomized Prospective Study.

BACKGROUND: There are few treatment options for mild-to-moderate anal incontinence with isolated internal anal sphincter defects or anal incontinence without muscle damage. Less-invasive techniques are generally favored. OBJECTIVE: To compare the results between the use of an anal bulking agent with polyacrylate-polyalcohol copolymer particles and endoanal electrical stimulation with biofeedback in patients with mild or moderate anal incontinence. DESIGN: This was a prospective parallel-group, single-institution, randomized clinical trial. SETTINGS: This study was conducted in an ambulatory setting at the Colorectal Physiology Service of the Hospital das Clinicas, Medical School, University of Sao Paulo. PATIENTS: This study included patients who had anal incontinence for >6 months with isolated internal anal sphincter muscle damage or absence of anatomical defects in the anorectal sphincter complex. INTERVENTIONS: Anal bulking agent and endoanal electrical stimulation with biofeedback. MAIN OUTCOME MEASURES: The primary outcome measure was the Cleveland Clinic Florida Fecal Incontinence Score, and the secondary outcome measures included quality of life, recommended procedures, and anorectal manometry. RESULTS: There were no significant between-group differences in mean age, sex, BMI, stool consistency, and Cleveland Clinic Florida Fecal Incontinence Score (p = 0.20) at baseline. After 12 months, the Cleveland Clinic Florida Fecal Incontinence Score was found to be significantly improved in patients treated with the bulking agent compared to those treated with electrical stimulation (mean, 6.2 vs 9.2; p = 0.002), though the anorectal manometry parameters did not change significantly. The mean anal Cleveland Clinic Florida Fecal Incontinence Score declined by 4.2 points in the bulking agent group compared to a decline of 0.8 in the electrical stimulation group (mean difference in decline: 3.4 points; 95% CI, 1.2-5.5). Quality-of life evaluation showed similar results between groups comparing baseline parameters with 12-month follow-up. LIMITATIONS: The short follow-up period of 1 year, atypical method of biofeedback, and unmatched baseline in some of the quality-of-life scales between the 2 groups limited this study. CONCLUSIONS: In patients with mild or moderate anal incontinence, the Cleveland Clinic Florida Fecal Incontinence Score significantly improved in the bulking agent with polyacrylate-polyalcohol copolymer group compared with the endoanal electrical stimulation with biofeedback group.

Systematic review and meta-analysis of colon capsule endoscopy accuracy for colorectal cancer screening. An alternative during the Covid-19 pandemic?

AIM: To determine the diagnostic accuracy of colon capsule endoscopy for colorectal cancer screening. METHODS: Studies that compared the diagnostic performance of colonoscopy and second-generation colon capsule endoscopy (CCE-2) for screening of asymptomatic patients aged 50-75 years were included. The primary outcomes were sensitivity, specificity, and positive and negative likelihood ratios for polyps and adenomas measuring at least 6 mm or 10 mm. RESULTS: Eight full-text studies that evaluated 1602 patients were included for systematic review. Of these, 840 (52.43%) patients participated in an opportunistic screening program. The pooled outcomes of CCE-2 for polyps at least 6 mm / 10 mm were (CI = confidence interval): sensitivity: 88% (95% CI: 0.84-0.91) / 88% (95% CI: 0.82-0.93), specificity: 94% (95% CI: 0.92-0.95) / 95.5% (95% CI: 0.94-0.97); positive likelihood ratio: 11.86 (95% CI: 5.53-25.46) / 23.07 (95% CI: 6.163-86.36); negative likelihood ratio: 0.14 (95% CI: 0.1-0.21) / 0.14 (95% CI: 0.09-0.21). The area under the summary receiver operating characteristic curve for polyps at least 6 and 10 mm was 96.3% and 96.7%, respectively. The only cancer missed by complete CCE-2 was shown at multiple frames in the unblinded review. In total, 125 (7.8%) patients presented mild adverse events mostly related to bowel preparation. CONCLUSION: CCE-2 is demonstrated to be an effective and safe alternative method for colorectal cancer screening. Diagnostic performance of CCE-2 for polyps of at least 6 and 10 mm was similar. Completion rates still need to be improved.

Outcomes of Patients With Local Regrowth After Nonoperative Management of Rectal Cancer After Neoadjuvant Chemoradiotherapy.

BACKGROUND: Clinical complete responders after chemoradiation for rectal cancer are increasingly being managed by a watch-and-wait strategy. Nonetheless, a significant proportion will experience a local regrowth, and the long-term oncological outcomes of these patients is not totally known. OBJECTIVE: The purpose of this study was to analyze the outcomes of patients who submitted to a watch-and-wait strategy and developed a local regrowth, and to compare these results with sustained complete clinical responders. DESIGN: This was a retrospective study. SETTING: Single institution, tertiary cancer center involved in alternatives to organ preservation. PATIENTS: Patients with a biopsy-proven rectal adenocarcinoma (stage II/III or low lying cT2N0M0 at risk for an abdominoperineal resection) treated with chemoradiation who were found at restage to have a clinical complete response. INTERVENTIONS: Rectal cancer patients treated with chemoradiation who underwent a watch-and-wait strategy (without a full thickness local excision) and developed a local regrowth were compared to the remaining patients of the watch-and-wait strategy. MAIN OUTCOME MEASURES: Overall survival between groups, incidence of regrowth' and results of salvage surgery. RESULTS: There were 67 patients. Local regrowth occurred in 20 (29.9%) patients treated with a watch-and-wait strategy. Mean follow-up was 62.7 months. Regrowth occurred at mean 14.2 months after chemoradiation, half of them within the first 12 months. Patients presented with comparable initial staging, lateral pelvic lymph-node metastasis, and extramural venous invasion. The regrowth group had a statistically nonsignificant higher incidence of mesorectal fascia involvement (35.0% vs 13.3%, p = 0.089). All regrowths underwent salvage surgery, mostly (75%) a sphincter-sparing procedure. 5-year overall survival was 71.1% in patients with regrowth and 91.1% in patients with a sustained complete clinical response (p = 0.027). LIMITATIONS: This study was limited by its retrospective evaluation of patient selection for a watch-and-wait strategy and outcomes, as well as its small sample size. CONCLUSIONS: Local regrowth is a frequent event when following a watch-and-wait policy (29.9%); however, patients could undergo salvage surgical treatment with adequate pelvic control. In this series, overall survival showed a statistically significant difference from patients managed with a watch-and-wait strategy who experienced a local regrowth compared to those who did not.

El rebrote local ocurrió en 20 (29,9%) pacientes tratados con una estrategia de observación y espera. El seguimiento medio fue de 62,7 meses. El rebrote se produjo a la media de 14,2 meses después de la quimiorradiación, la mitad de ellos dentro de los primeros 12 meses. Los pacientes se presentaron con una estadificación inicial comparable, metástasis en los ganglios linfáticos pélvicos laterales e invasión venosa extramural. El grupo de rebrote tuvo una mayor incidencia estadísticamente no significativa de afectación de la fascia mesorrectal (35,0 vs 13,3%, p = 0,089). Todos los rebrotes se sometieron a cirugía de rescate, en su mayoría (75%) con procedimiento de preservación del esfínter. La supervivencia global a 5 años fue del 71,1% en pacientes con rebrote y del 91,1% en pacientes con una respuesta clínica completa sostenida (p = 0,027).LIMITACIONES:Evaluación retrospectiva de la selección de pacientes para una estrategia y resultados de observar y esperar, tamaño de muestra pequeño.CONCLUSIONES:El rebrote local es un evento frecuente después de la política de observación y espera (29,9%), sin embargo los pacientes podrían someterse a un tratamiento quirúrgico de rescate con un adecuado control pélvico. En esta serie, la supervivencia global mostró una diferencia estadísticamente significativa de los pacientes manejados con una estrategia de observación y espera que experimentaron un rebrote local, en comparación con los que no lo hicieron.

Even though the association of techniques may raise pain scores, a tailored approach based on amplified indication criteria and combined techniques seems to be an effective and safe alternative, with decreased relapse rates in patients suffering from more advanced hemorrhoidal disease. Satisfaction scores after hemorrhoidopexy are high.

RESUMO RACIONAL: Desde sua introdução, a hemorroidopexia por grampeamento tem sido cada vez mais indicada no manuseio da doença hemorroidária. OBJETIVOS: Nosso objetivo primário foi avaliar a incidência de doença recidivada que requeira tratamento cirúrgico. Numa análise secundária, também comparamos dor, complicações e satisfação do paciente após uma operação ajustada a cada caso. MÉTODOS: Foram revistos retrospectivamente 196 pacientes (103 homens e 93 mulheres) com idade média de 47,9 anos (17-78) submetidos a hemorroidopexia mecânica isoladamente (STG; n=65) ou cirurgia combinada (CSG; n=131, hemorroidopexia por grampeamento com ressecção). RESULTADOS: Complicações foram detectadas 11 (5,6%) pacientes (4,6% para STG vs. 6,1% para CSG; p=0,95). Ao mesmo tempo, recidiva de sintomas (13,8% vs. 8,4%; p=034), reoperações por complicações (3,1% vs. 3,0%; p=1,0) ou por recidiva (6,1 vs. 4,6%; p=1,0) não foram diferentes entre os dois grupos. Pacientes com grau IV foram mais comumente manuseados com grampeamento e ressecção simultâneos (63% vs. 49,5%), mas nenhum deles apresentou recidiva ou necessitou reoperação. O escore médio de dor na primeira semana foi maior no grupo CSG (0,8 vs. 1,7). Após seguimento de 24,9 meses, os índices de satisfação foram similares (8,6; p=0,8). CONCLUSÕES: Sintomas de recidiva foram observados em 10%, requerendo cirurgia em aproximadamente metade dos doentes. Embora a associação de técnicas aumente os escores de dor, um procedimento sob medida baseado em critérios ampliados de indicação e técnicas combinadas parece ser uma alternativa efetiva e segura, com menor recidiva em pacientes portadores de doença hemorroidária mais avançada. Os escores de satisfação após hemorroidopexia são altos.

Surgical technique and considerations about transanal transection and single-stapled (TTSS) anastomosis: the search for a perfect anastomosis

The evaluation of preventivemeasures and risk factors for anastomotic leakage has been a constant concern among colorectal surgeons. In this context, the description of a new way to perform a colorectal, coloanal or ileoanal anastomosis, known as transanal transection and single-stapled (TTSS) anastomosis, deserves an appreciation of its qualities, and a discussion about its properties and technical details. In the present paper, the authors review themost recent efforts aiming to reduce anastomotic dehiscence, and describe the TTSS technique in a patient submitted to laparoscopic total proctocolectomy with ileal pouch-anal anastomosis for familial adenomatous polyposis. Surgical perception raises important advantages such as distal rectal transection under visualization, elimination of double-stapling lines (with cost-effectiveness and potential protection against suture dehiscence), elimination of dog ears, and the opportunity to be accomplished via a transanal approach after open, laparoscopic, or robotic colorectal resections. Future studies to confirm these supposed advantages are needed. (AU)
