RESUMEN

BACKGROUND: Perineal hernias can be secondarily acquired following abdominoperineal resection of the rectum. While transabdominal minimally invasive techniques have traditionally used laparoscopy, there are few studies published on the robotic platform, which has been gaining popularity for other types of hernia repairs. We review the existing literature, share a video vignette, and provide practical tips for surgeons interested in adopting this approach. METHODS: A literature search in Pubmed was performed to include all articles in English describing robotic repair of perineal hernias with identification of variables of interest related to repair. A case presentation with an accompanying video vignette and lessons learned from the experience are provided. RESULTS: Seven case reports (four containing video) published between 2019 and 2022 were included. Most articles (n = 5) utilized the Da Vinci Si or Xi, and most patients (n = 5) had undergone abdominoperineal resection with neoadjuvant chemotherapy to treat rectal cancer. Patients were positioned in Trendelenburg with rightward tilt (n = 2), modified lithotomy (n = 1), or a combination of the two (n = 1). All articles (n = 7) reported closing the defect and using mesh. Three articles describe placing five ports (one camera, three robotic, one assistant). There were no significant intraoperative or postoperative complications reported, and no recurrence noted at 3-27 months follow-up. Based on our experience, as shown in the video vignette, we recommend lithotomy positioning, using porous polypropylene mesh anchored to the periosteum of the sacrum and peritoneum overlying the bladder and side wall, and placing a drain above the mesh. CONCLUSIONS: A robotic transabdominal approach to perineal hernia repair is a viable alternate to laparoscopy based on low complication rates and lack of recurrence. Prospective and longer duration data are needed to compare the techniques.

RESUMEN

BACKGROUND: Indocyanine green fluoroscopy has been shown to improve anastomotic leak rates in early phase trials. OBJECTIVE: We hypothesized that the use of fluoroscopy to ensure anastomotic perfusion may decrease anastomotic leak after low anterior resection. DESIGN: We performed a 1:1 randomized controlled parallel study. Recruitment of 450 to 1000 patients was planned over 2 years. SETTINGS: This was a multicenter trial. PATIENTS: Included patients were those undergoing resection defined as anastomosis within 10 cm of the anal verge. INTERVENTION: Patients underwent standard evaluation of tissue perfusion versus standard in conjunction with perfusion evaluation using indocyanine green fluoroscopy. MAIN OUTCOME MEASURES: Primary outcome was anastomotic leak, with secondary outcomes of perfusion assessment and the rate of postoperative abscess requiring intervention. RESULTS: This study was concluded early because of decreasing accrual rates. A total of 25 centers recruited 347 patients, of whom 178 were randomly assigned to perfusion and 169 to standard. The groups had comparable tumor-specific and patient-specific demographics. Neoadjuvant chemoradiation was performed in 63.5% of perfusion and 65.7% of standard (p > 0.05). Mean level of anastomosis was 5.2 ± 3.1 cm in perfusion compared with 5.2 ± 3.3 cm in standard (p > 0.05). Sufficient visualization of perfusion was reported in 95.4% of patients in the perfusion group. Postoperative abscess requiring surgical management was reported in 5.7% of perfusion and 4.2% of standard (p = 0.75). Anastomotic leak was reported in 9.0% of perfusion compared with 9.6% of standard (p = 0.37). On multivariate regression analysis, there was no difference in anastomotic leak rates between perfusion and standard (OR = 0.845 (95% CI, 0.375-1.905); p = 0.34). LIMITATIONS: The predetermined sample size to adequately reduce the risk of type II error was not achieved. CONCLUSIONS: Successful visualization of perfusion can be achieved with indocyanine green fluoroscopy. However, no difference in anastomotic leak rates was observed between patients who underwent perfusion assessment versus standard surgical technique. In experienced hands, the addition of routine indocyanine green fluoroscopy to standard practice adds no evident clinical benefit. See Video Abstract at http://links.lww.com/DCR/B560. VALORACIN DE LA IRRIGACIN DE LADO IZQUIERDO/RESECCIN ANTERIOR BAJA PILAR III UN ESTUDIO ALEATORIZADO, CONTROLADO, PARALELO Y MULTICNTRICO QUE EVALA LOS RESULTADOS DE LA IRRIGACIN CON PINPOINT IMGENES DE FLUORESCENCIA CERCANA AL INFRARROJO EN LA RESECCIN ANTERIOR BAJA: ANTECEDENTES:Se ha demostrado que la fluoroscopia con verde de indocianina mejora las tasas de fuga anastomótica en ensayos en fases iniciales.OBJETIVO:Nuestra hipótesis es que la utilización de fluoroscopia para asegurar la irrigación anastomótica puede disminuir la fuga anastomótica luego de una resección anterior baja.DISEÑO:Realizamos un estudio paralelo, controlado, aleatorizado 1:1. Se planificó el reclutamiento de 450-1000 pacientes durante 2 años.AMBITO:Multicéntrico.PACIENTES:Pacientes sometidos a resección definida como una anastomosis dentro de los 10cm del margen anal.INTERVENCIÓN:Pacientes que se sometieron a la evaluación estándar de la irrigación tisular contra la estándar en conjunto con la valoración de la irrigación mediante fluoroscopia con verde indocianina.PRINCIPALES VARIABLES EVALUADAS:El principal resultado fue la fuga anastomótica, y los resultados secundarios fueron la evaluación de la perfusión y la tasa de absceso posoperatorio que requirió intervención.RESULTADOS:Este estudio se cerró anticipadamente debido a la disminución de las tasas de acumulación. Un total de 25 centros reclutaron a 347 pacientes, de los cuales 178 fueron, de manera aleatoria, asignados a perfusión y 169 a estándar. Los grupos tenían datos demográficos específicos del tumor y del paciente similares. Recibieron quimio-radioterapia neoadyuvante el 63,5% de la perfusión y el 65,7% del estándar (p> 0,05). La anastomosis estuvo en un nivel promedio de 5,2 + 3,1 cm en perfusión en comparación con 5,2 + 3,3 cm en estándar (p> 0,05). Se reportó una visualización suficiente de la perfusión en el 95,4% de los pacientes del grupo de perfusión. El absceso posoperatorio que requirió tratamiento quirúrgico fue de 5,7% de los perfusion y en el 4,2% del estándar (p = 0,75). Se informó fuga anastomótica en el 9,0% de la perfusión en comparación con el 9,6% del estándar (p = 0,37). En el análisis de regresión multivariante, no hubo diferencias en las tasas de fuga anastomótica entre la perfusión y el estándar (OR 0,845; IC del 95% (0,375; 1,905); p = 0,34).LIMITACIONES:No se logró el tamaño de muestra predeterminado para reducir satisfactoriamente el riesgo de error tipo II.CONCLUSIÓN:Se puede obtener una visualización adecuada de la perfusión con ICG-F. Sin embargo, no se observaron diferencias en las tasas de fuga anastomótica entre los pacientes que se sometieron a evaluación de la perfusión versus la técnica quirúrgica estándar. En manos expertas, agregar ICG-F a la rutina de la práctica estándar no agrega ningún beneficio clínico evidente. Consulte Video Resumen en http://links.lww.com/DCR/B560.

RESUMEN

BACKGROUND: Adding modified FOLFOX6 (folinic acid, fluorouracil, and oxaliplatin) after chemoradiotherapy and lengthening the chemoradiotherapy-to-surgery interval is associated with an increase in the proportion of rectal cancer patients with a pathological complete response. OBJECTIVE: The purpose of this study was to analyze disease-free and overall survival. DESIGN: This was a nonrandomized phase II trial. SETTINGS: The study was conducted at multiple institutions. PATIENTS: Four sequential study groups with stage II or III rectal cancer were included. INTERVENTION: All of the patients received 50 Gy of radiation with concurrent continuous infusion of fluorouracil for 5 weeks. Patients in each group received 0, 2, 4, or 6 cycles of modified FOLFOX6 after chemoradiation and before total mesorectal excision. Patients were recommended to receive adjuvant chemotherapy after surgery to complete a total of 8 cycles of modified FOLFOX6. MAIN OUTCOME MEASURES: The trial was powered to detect differences in pathological complete response, which was reported previously. Disease-free and overall survival are the main outcomes for the current study. RESULTS: Of 259 patients, 211 had a complete follow-up. Median follow-up was 59 months (range, 9-125 mo). The mean number of total chemotherapy cycles differed among the 4 groups (p = 0.002), because one third of patients in the group assigned to no preoperative FOLFOX did not receive any adjuvant chemotherapy. Disease-free survival was significantly associated with study group, ypTNM stage, and pathological complete response (p = 0.004, <0.001, and 0.001). A secondary analysis including only patients who received ≥1 cycle of FOLFOX still showed differences in survival between study groups (p = 0.03). LIMITATIONS: The trial was not randomized and was not powered to show differences in survival. Survival data were not available for 19% of the patients. CONCLUSIONS: Adding modified FOLFOX6 after chemoradiotherapy and before total mesorectal excision increases compliance with systemic chemotherapy and disease-free survival in patients with locally advanced rectal cancer. Neoadjuvant consolidation chemotherapy may have benefits beyond increasing pathological complete response rates. See Video Abstract at http://links.lww.com/DCR/A739.

RESUMEN

OBJECTIVE: The purpose of this study was to determine if extended PET acquisition times in the pelvis during PET/MRI increase detection rates of potentially metastatic lymph nodes in patients with rectal cancer. MATERIALS AND METHODS: Our study was approved by the institutional review board of the University of California, San Francisco. Twenty-two patients with biopsy-proven rectal cancer underwent imaging via simultaneous 3-T time-of-flight PET/MRI, with seven undergoing two separate PET/MRI examinations, for a total of 29 studies. Each examination included both a whole-body PET/MRI and a dedicated pelvic PET/MRI with both 3- and 15-minute PET acquisitions for the pelvis. Three radiologists interpreted each examination with PET only, MRI only, then combined PET and MRI examinations, using all available images. Additionally, the 3- and 15-minute PET acquisitions of the pelvis were reviewed separately by a single radiologist. RESULTS: A total of 94 lymph nodes were identified as abnormal on PET, all with MRI anatomic correlates. Of these, 37 (39.4%) were seen only on the dedicated 15-minute acquisition. Fifty-seven (60.6%) nodes measured 5 mm or less, including 29 (30.9%) seen only on the 15-minute acquisition. Thirty-one (33.0%) nodes measured 5.1-10 mm, including eight (25.8%) seen only on the 15-minute acquisition. Of the 17 subjects imaged for initial staging, 11 (64.7%) were upstaged as a result of the increased PET acquisition time (10 from N1 to N2 and one from N0 to N1). CONCLUSION: Longer PET acquisition times during PET/MRI for rectal cancer increases the number of FDG-avid lymph nodes detected without increasing scan time.

RESUMEN

BACKGROUND: Up to 30% of patients who have ulcerative colitis are faced with the complex decision between end ileostomy and IPAA. We developed a decision aid to encourage shared decision making between patients and surgeons. OBJECTIVE: The aim of this study is to determine whether a decision aid is effective and acceptable for surgical patients with ulcerative colitis and their treating surgeons. DESIGN: This was a prospective cohort study. SETTINGS: Patients and surgeons were enrolled from 3 colorectal surgery clinics. PATIENTS: Consecutive adult patients with ulcerative colitis who were candidates for IPAA and end ileostomy were selected. INTERVENTIONS: Patients used a multilingual decision aid before meeting with the surgeon. MAIN OUTCOME MEASURES: We measured changes in knowledge, treatment preference, and stage of decision making, as well as preparation for decision making, patient satisfaction, and surgeon satisfaction after using the decision aid. RESULTS: Twenty-five patients were enrolled; 5 had previously undergone subtotal colectomy. After using the decision aid, patients' knowledge scores improved by 39% (p < 0.006), 6 patients changed their treatment preference, and 8 reported increased certainty in treatment preference. The median for preparation for decision making was 75 of 100. Patient satisfaction with the decision aid (median score, 37/41) and surgeon satisfaction with the clinical encounter (median score, 38/45) were high. Patients who previously underwent subtotal colectomy had lower preparation for decision-making scores (median score, 58 vs 78 for surgery-naïve patients, p = 0.06), and did not report increased certainty in treatment preference after using the decision aid. LIMITATIONS: The study included a small sample with no comparison group. CONCLUSIONS: A novel decision aid for surgical patients with ulcerative colitis appears to be effective and acceptable in patients and surgeons from diverse clinical settings. Patients who have not yet initiated surgical treatment seem to benefit most. Future studies to validate the knowledge questionnaire and test the decision aid in a randomized fashion are warranted.

RESUMEN

BACKGROUND: Bowel dysfunction, including frequency, fecal urgency, stool consistency, and evacuation symptoms, contributes to fecal incontinence. OBJECTIVE: The purpose of this study was to examine the impact of a vaginal bowel control system on parameters of bowel function, including frequency, urgency, stool consistency, and evacuation. DESIGN: This was a secondary analysis of a multicenter, prospective clinical trial. SETTINGS: This study was conducted at 6 sites in the United States, including university hospitals and private practices in urogynecology and colorectal surgery. PATIENTS: A total of 56 evaluable female subjects aged 19 to 75 years with 4 or more fecal incontinence episodes on a 2-week bowel diary were included. INTERVENTIONS: The study intervention was composed of the vaginal bowel control system, consisting of a vaginal insert and pressure-regulated pump. MAIN OUTCOME MEASURES: Subjects completed a 2-week baseline diary of bowel function before and after treatment completed at 1 month. Fecal urgency, consistency of stool (Bristol score), and completeness of evacuation were recorded for all bowel movements. RESULTS: Use of the insert was associated with an improvement in bowel function across all 4 categories. Two thirds (8/12) of subjects with a high frequency of daily stools (more than 2 per day) shifted to a normal or low frequency of stools. Analysis of Bristol stool scale scores demonstrated a significant reduction in the proportion of all bowel movements reported as liquid (Bristol 6 or 7), from 36% to 21% (p = 0.0001). On average, 54% of stools were associated with urgency at baseline compared with 26% at 1 month (p < 0.0001). Incomplete evacuations with all bowel movements were reduced from 39% to 26% of subjects at 1 month (p = 0.0034). LIMITATIONS: The study follow-up period was 1 month (with an optional additional 2 months). CONCLUSIONS: The vaginal bowel control system was associated with an improvement in bowel symptoms and function, including reduced bowel movement frequency, less fecal urgency, increased solid consistency, and improved evacuation in patients with significant fecal incontinence.

RESUMEN

BACKGROUND: Despite international data indicating that Enhanced Recovery After Surgery (ERAS) programs, which combine evidence-based perioperative strategies, expedite recovery after surgery, few centers have successfully adopted this approach within the U.S. We describe the implementation and efficacy of an ERAS program for colorectal abdominal surgery in a tertiary teaching center in the U.S. METHODS: We used a multi-modal and continuously evolving approach to implement an ERAS program among all patients undergoing colorectal abdominal surgery at a single hospital at the University of California, San Francisco. 279 patients who participated in the Enhanced Recovery after Surgery program were compared to 245 previous patients who underwent surgery prior to implementation of the program. Primary end points were length of stay and readmission rates. Secondary end points included postoperative pain scores, opioid consumption, postoperative nausea and vomiting, length of urinary catheterization, and time to first solid meal. RESULTS: ERAS decreased both median total hospital length of stay (6.4 to 4.4 days) and post-procedure length of stay (6.0 to 4.1 days). 30-day all-cause readmission rates decreased from 21 to 9.4 %. Pain scores improved on postoperative day 0 (3.2 to 2.1) and day 1 (3.2 to 2.6) despite decreased opioid. Median time to first solid meal decreased from 4.7 to 2.7 days and duration of urinary catheterization decreased from 74 to 46 h. Similar improvements were observed in all other secondary end points. CONCLUSIONS: These results confirm that a multidisciplinary, iterative, team-based approach is associated with a reduction in hospital stay and an acceleration in recovery without increasing readmission rates.

RESUMEN

BACKGROUND: Patients with locally advanced rectal cancer who achieve a pathological complete response to neoadjuvant chemoradiation have an improved prognosis. The need for surgery in these patients has been questioned, but the proportion of patients achieving a pathological complete response is small. We aimed to assess whether adding cycles of mFOLFOX6 between chemoradiation and surgery increased the proportion of patients achieving a pathological complete response. METHODS: We did a phase 2, non-randomised trial consisting of four sequential study groups of patients with stage II-III locally advanced rectal cancer at 17 institutions in the USA and Canada. All patients received chemoradiation (fluorouracil 225 mg/m(2) per day by continuous infusion throughout radiotherapy, and 45·0 Gy in 25 fractions, 5 days per week for 5 weeks, followed by a minimum boost of 5·4 Gy). Patients in group 1 had total mesorectal excision 6-8 weeks after chemoradiation. Patients in groups 2-4 received two, four, or six cycles of mFOLFOX6, respectively, between chemoradiation and total mesorectal excision. Each cycle of mFOLFOX6 consisted of racemic leucovorin 200 mg/m(2) or 400 mg/m(2), according to the discretion of the treating investigator, oxaliplatin 85 mg/m(2) in a 2-h infusion, bolus fluorouracil 400 mg/m(2) on day 1, and a 46-h infusion of fluorouracil 2400 mg/m(2). The primary endpoint was the proportion of patients who achieved a pathological complete response, analysed by intention to treat. This trial is registered with ClinicalTrials.gov, number NCT00335816. FINDINGS: Between March 24, 2004, and Nov 16, 2012, 292 patients were registered, 259 of whom (60 in group 1, 67 in group 2, 67 in group 3, and 65 in group 4) met criteria for analysis. 11 (18%, 95% CI 10-30) of 60 patients in group 1, 17 (25%, 16-37) of 67 in group 2, 20 (30%, 19-42) of 67 in group 3, and 25 (38%, 27-51) of 65 in group 4 achieved a pathological complete response (p=0·0036). Study group was independently associated with pathological complete response (group 4 compared with group 1 odds ratio 3·49, 95% CI 1·39-8·75; p=0·011). In group 2, two (3%) of 67 patients had grade 3 adverse events associated with the neoadjuvant administration of mFOLFOX6 and one (1%) had a grade 4 adverse event; in group 3, 12 (18%) of 67 patients had grade 3 adverse events; in group 4, 18 (28%) of 65 patients had grade 3 adverse events and five (8%) had grade 4 adverse events. The most common grade 3 or higher adverse events associated with the neoadjuvant administration of mFOLFOX6 across groups 2-4 were neutropenia (five in group 3 and six in group 4) and lymphopenia (three in group 3 and four in group 4). Across all study groups, 25 grade 3 or worse surgery-related complications occurred (ten in group 1, five in group 2, three in group 3, and seven in group 4); the most common were pelvic abscesses (seven patients) and anastomotic leaks (seven patients). INTERPRETATION: Delivery of mFOLFOX6 after chemoradiation and before total mesorectal excision has the potential to increase the proportion of patients eligible for less invasive treatment strategies; this strategy is being tested in phase 3 clinical trials.

RESUMEN

BACKGROUND: Little is known about how obstructive defecation and colonic inertia symptoms contribute to constipation-related quality of life. OBJECTIVE: We sought to characterize the differences in quality of life in patients with severe obstructive defecation and colonic inertia symptoms. DESIGN: This study was a cross-sectional analysis of a prospective database. SETTING: Patients were enrolled at a single tertiary referral center. PATIENTS: We included consecutive adults with severe symptoms of obstructive defecation (n = 115) or colonic inertia (n = 90) as measured by the Constipation Severity Instrument. MAIN OUTCOME MEASURES: The primary outcomes measured were the Pelvic Floor Distress Inventory, Constipation-Related Quality of Life instrument, Pelvic Floor Impact Questionnaire, and 12-item Short Form Health Survey. RESULTS: Although physical examination and anorectal physiology testing were similar between groups, patients with severe obstructive defecation symptoms reported worse pain, distress, and constipation-specific quality of life than patients with severe colonic inertia symptoms (all p < 0.001). Specifically, patients with severe obstructive defecation symptoms showed greater quality-of-life impairment related to eating, bathroom habits, and social functioning (all p ≤ 0.01). Furthermore, patients with severe obstructive defecation symptoms had inferior global quality of life on the 12-item Short Form Health Survey physical component score (p = 0.03) and mental component score (p = 0.06). LIMITATIONS: The use of patient self-report instruments resulted in a proportion of patients with incomplete data. CONCLUSION: Quality of life was impaired in both groups of patients; however, patients with severe obstructive defecation symptoms were affected to a significantly greater extent. The fact that there were no differences in objective findings on physical examination or anorectal physiology studies highlights the importance of assessing quality of life during the evaluation and treatment of constipated patients.

RESUMEN

BACKGROUND: Historically, older patients with ulcerative colitis were not considered candidates for ileal pouch-anal anastomosis. However, more recent evidence suggests that this procedure can be performed in older patients with acceptable surgical and functional results. OBJECTIVE: The purpose of this work was to determine whether older age is independently associated with surgical procedure type among patients with ulcerative colitis in a large national database. DESIGN: This was a cross-sectional analysis of ulcerative colitis patients undergoing end ileostomy or IPAA, grouped by age. SETTINGS: This study was conducted in a university teaching hospital. PATIENTS: Patients with ulcerative colitis who underwent total proctocolectomy or completion proctectomy with either IPAA or end ileostomy from 2005 to 2012 in the American College of Surgeons National Surgery Quality Improvement Program database were included in this study. MAIN OUTCOME MEASURES: The primary outcome was procedure type (end ileostomy or IPAA). Patient factors associated with procedure type, including age and trends over time, were examined using multivariate logistic regression. RESULTS: Among 3635 patients with ulcerative colitis, 28.2% underwent end ileostomy and 71.8% underwent IPAA. Older patients were more likely to undergo end ileostomy than patients ≤50 years of age after adjustment for sex, smoking, BMI, frailty trait count, and ASA class (p < 0.001). The odds of end ileostomy decreased by 12% per year between 2005 and 2012 in patients aged 61 to 70 years compared with patients ≤50 years of age (adjusted OR, 0.88 per year; p = 0.021). LIMITATIONS: We were unable to analyze other potentially important determinants of procedure type, such as surgeon, patient preference, and anal sphincter integrity. CONCLUSIONS: Age remains strongly associated with procedure type. The use of end ileostomy, however, is decreasing over time in patients 61 to 70 years of age as evidence accumulates that IPAA is an acceptable option for older patients with ulcerative colitis (see Video, Supplemental Digital Content 1, http://links.lww.com/DCR/A191).

RESUMEN

BACKGROUND: Although social support is important for quality of life in patients undergoing surgery for ulcerative colitis, the impact of surgery on patient relationships is not known. OBJECTIVE: We examined relationship parameters in patients with ulcerative colitis and their partners before and 6 months after surgery. DESIGN: This was a prospective cohort in which we performed an exploratory analysis. SETTINGS: Patients were enrolled from an academic medical center. PATIENTS: Surgical patients with ulcerative colitis and their partners were invited to participate. INTERVENTIONS: Patients underwent proctocolectomy in 1, 2, or 3 stages. MAIN OUTCOME MEASURES: We measured quality of life and sexual function in patients, as well as relationship quality, empathy, and sexual satisfaction in patients and partners before and 6 months after surgery using validated questionnaires. RESULTS: The study sample consisted of 74 participants, including 37 patients (25 men and 12 women) and their opposite-sex partners. Quality of life improved significantly in male and female patients after surgery. Sexual function scores also improved after surgery in male and female patients; however, the changes reached statistical significance in male patients only. Sexual satisfaction scores improved significantly after surgery in female patients and their partners. There was little change in relationship quality or empathy after surgery, with the exception of slightly improved relationship quality reported by male partners. In general, patients and partners reported levels of relationship quality and empathy similar to normative populations. LIMITATIONS: This study included a small, highly selected sample. CONCLUSIONS: Male and female patients with ulcerative colitis have high-quality relationships that are not negatively affected by surgical treatment. Changes in sexual function do not necessarily coincide with changes in sexual satisfaction in this patient population. Future studies should evaluate the effect of high-quality relationships on surgical outcomes.

RESUMEN

BACKGROUND: Evidence from single-center studies suggests that ileal pouch-anal anastomosis (IPAA) can be safely performed in selected older patients with ulcerative colitis. The impact of age and frailty on surgical outcomes and hospital length of stay after IPAA has not been examined. METHODS: We identified all patients with ulcerative colitis who underwent total proctocolectomy or completion proctectomy with IPAA in the National Surgery Quality Improvement Program database from 2005-2012. We examined the associations of age and frailty trait count with length of hospital stay and surgical complications using multivariate regression. RESULTS: IPAA was performed in 2493 patients with ulcerative colitis. Thirty-day mortality was 0.2% (n = 6). The majority of patients had no serious postoperative complications (age ≤50 y: 79.5%, age 51-60 y: 80.4%, and age >60 y: 79.1%). After multivariate risk adjustment, patients aged >60 y had a similar mean number of complications as patients aged ≤50 y (0.31 versus 0.35, P = 0.47) and a 0.8-d longer mean length of hospital stay (7.4 versus 8.2 d, P = 0.035). Compared to patients with zero frailty traits, a frailty trait count ≥1 was associated with a similar mean number of complications (0.31 versus 0.34, P = 0.36) and length of hospital stay (7.4 versus 7.7 d, P = 0.25). CONCLUSIONS: In this analysis of patients undergoing IPAA at National Surgery Quality Improvement Program hospitals, surgical complications were not substantially increased in older patients or those with frailty traits. Older age was associated with a small increase in hospital length of stay. These findings suggest that IPAA is safe in selected older adults with ulcerative colitis.

RESUMEN

BACKGROUND: Repair of grade 3 and grade 4 ventral hernias is a distinct challenge, given the potential for infection, and the comorbid nature of the patient population. This study evaluates our institutional outcomes when performing single-stage repair of these hernias, with biologic mesh for abdominal wall reinforcement. METHODS: A prospectively maintained database was reviewed for all patients undergoing repair of grade 3 (potentially contaminated) or grade 4 (infected) hernias, as classified by the Ventral Hernia Working Group. All those patients undergoing repair with component separation techniques and biologic mesh reinforcement were included. Patient demographics, comorbidities, and postoperative complications were analyzed. Univariate analysis was performed to define factors predictive of hernia recurrence and wound complications. RESULTS: A total of 41 patients underwent single-stage repair of grade 3 and grade 4 hernias during a 4-year period. The overall postoperative wound infection rate was 15%, and hernia recurrence rate was 12%. Almost all recurrences were seen in grade 4 hernia repairs, and in those patients undergoing bridging repair of the hernia. One patient required removal of the biologic mesh. Those factors predicting hernia recurrence were smoking (P = 0.023), increasing body mass index (P = 0.012), increasing defect size (P = 0.010), and bridging repair (P = 0.042). No mesh was removed due to perioperative infection. Mean follow-up time for this patient population was 25 months. CONCLUSIONS: Single-stage repair of grade 3 hernias performed with component separation and biologic mesh reinforcement is effective and offers a low recurrence rate. Furthermore, the use of biologic mesh allows for avoidance of mesh explantation in instances of wound breakdown or infection. Bridging repairs are associated with a high recurrence rate, as is single-stage repair of grade 4 hernias.

RESUMEN

Clinical trials frequently include multiple end points that mature at different times. The initial report, typically based on the primary end point, may be published when key planned co-primary or secondary analyses are not yet available. Clinical Trial Updates provide an opportunity to disseminate additional results from studies, published in JCO or elsewhere, for which the primary end point has already been reported.To assess long-term risk of local tumor regrowth, we report updated organ preservation rate and oncologic outcomes of the OPRA trial (ClinicalTrials.gov identifier: NCT02008656). Patients with stage II/III rectal cancer were randomly assigned to receive induction chemotherapy followed by chemoradiation (INCT-CRT) or chemoradiation followed by consolidation chemotherapy (CRT-CNCT). Patients who achieved a complete or near-complete response after finishing treatment were offered watch-and-wait (WW). Total mesorectal excision (TME) was recommended for those who achieved an incomplete response. The primary end point was disease-free survival (DFS). The secondary end point was TME-free survival. In total, 324 patients were randomly assigned (INCT-CRT, n = 158; CRT-CNCT, n = 166). Median follow-up was 5.1 years. The 5-year DFS rates were 71% (95% CI, 64 to 79) and 69% (95% CI, 62 to 77) for INCT-CRT and CRT-CNCT, respectively (P = .68). TME-free survival was 39% (95% CI, 32 to 48) in the INCT-CRT group and 54% (95% CI, 46 to 62) in the CRT-CNCT group (P = .012). Of 81 patients with regrowth, 94% occurred within 2 years and 99% occurred within 3 years. DFS was similar for patients who underwent TME after restaging (64% [95% CI, 53 to 78]) and patients in WW who underwent TME after regrowth (64% [95% CI, 53 to 78]; P = .94). Updated analysis continues to show long-term organ preservation in half of the patients with rectal cancer treated with total neoadjuvant therapy. In patients who enter WW, most cases of tumor regrowth occur in the first 2 years.

RESUMEN

Introduction Establishing a scale that can easily be used to appropriately measure the impact of constipation on the quality of life in Japan is a first step toward addressing this important health issue. We developed a Japanese language version of the Constipation-Related Quality of Life scale, which has 18 items and four subscales, and then subjected it to validation testing. Methods After translation according to a standardized and commonly used procedure, the Japanese version of the Constipation-Related Quality of Life scale was administered to people in an internet-based panel, in March 2023. The participants included 1,276 adults who had constipation (median age: 60 years, 690 {54.1%} males). The outcome measures included the Constipation-Related Quality of Life scale, the Constipation Scoring System (an index of constipation severity), and the Medical Outcomes Study (MOS) eight-item short form (a measure of generic health-related quality of life). Results Confirmatory factor analysis (four-factor model) indicated that all 18 Constipation-Related Quality of Life items had sufficiently high factor loadings (0.686-0.926). Internal consistency reliability was high (Cronbach's alpha: 0.86-0.94). Scores on the social impairment subscale and on the distress subscale of the Constipation-Related Quality of Life scale were significantly worse in the participants who had worse scores on the social functioning and mental health domains, respectively, of the MOS eight-item short form, which indicates good concurrent validity. Regarding criterion-based validity, the four subscale scores differed significantly among the four constipation-severity groups. The four subscale scores were also 1.16-4.53 times more sensitive than the MOS eight-item short form's mental component score to differences among the four constipation-severity groups (relative validity: 1.16-4.53), which indicates good discriminant validity. Conclusion The Japanese version of the Constipation-Related Quality of Life scale can be used with confidence in its factor structure, its concurrent, criterion-based, and discriminant validity, and its internal consistency reliability.

RESUMEN

PURPOSE: We sought to determine whether adherence to the American Cancer Society (ACS) Nutrition and Physical Activity Guidelines was associated with better bowel function among colon cancer survivors. METHODS: This prospective cohort study included patients surgically treated for stage I-IV colon cancer enrolled in the Lifestyle and Outcomes after Gastrointestinal Cancer (LOGIC) study between February 2017 and May 2021. Participants were assigned an ACS score (0-6 points) at enrollment. Stool frequency (SF) was assessed every 6 months using the EORTC QLQ-CR29. Higher SF is an indication of bowel function impairment. ACS score at enrollment was examined in relation to SF at enrollment and over a 3-year period. Secondarily, we examined associations between the ACS score components (body mass index, dietary factors, and physical activity) and SF. Multivariable models were adjusted for demographic and surgical characteristics. RESULTS: A total of 112 people with colon cancer (59% women, mean age 59.5 years) were included. Cross-sectionally, for every point increase in ACS score at enrollment, the odds of having frequent stools at enrollment decreased by 43% (CI 0.42-0.79; p < 0.01). Findings were similar when we examined SF as an ordinal variable and change in SF over a 3-year period. Lower consumption of red/processed meats and consuming a higher number of unique fruits and vegetables were associated with lower SF (better bowel function) at enrollment. CONCLUSIONS: Colon cancer survivors who more closely followed the ACS nutrition and physical activity guidelines had lower SF, an indication of better bowel function. IMPLICATIONS FOR CANCER SURVIVORS: Our findings highlight the value of interventions that support health behavior modification as part of survivorship care for long-term colon cancer survivors.
