RESUMEN
INTRODUCTION: Acute appendicitis is the most common non-obstetrical surgical emergency in pregnancy. Ultrasound is the imaging tool of choice, but its use is complicated due to anatomical changes during pregnancy and depends on the clinician's expertise. In this study, our aim was to investigate the diagnostic accuracy of point-of-care ultrasound (POCUS) in suspected appendicitis in pregnant women. METHODS: We conducted a retrospective analysis of all pregnant women undergoing POCUS for suspected appendicitis between June 2010-June 2020 in a tertiary emergency department. The primary outcome was to establish sensitivity, specificity, and likelihood ratios of POCUS in diagnosing acute appendicitis, overall and for each trimester. We used histology of the appendix as the reference standard in case of surgery. If appendectomy was not performed, the clinical course until childbirth was used to rule out appendicitis. If the patients underwent magnetic resonance imaging (MRI), we compared readings to POCUS. RESULTS: A total of 61 women were included in the study, of whom 34 (55.7%) underwent appendectomy and in 30 (49.2%) an acute appendicitis was histopathologically confirmed. Sensitivity of POCUS was 66.7% (confidence interval [CI] 95% 47.1-82.7), specificity 96.8% (CI 95% 83.3-99.9), and positive likelihood ratio 20.7. Performance of POCUS was comparable in all trimesters, with highest sensitivity in the first trimester (72.7%). The MRI reading showed a sensitivity of 84.6% and a specificity of 100%. In the four negative appendectomies a MRI was not performed. CONCLUSION: Point-of-care ultrasound showed a high specificity and positive likelihood ratio in diagnosing acute appendicitis in pregnant women in all trimesters with suspected appendicitis. In negative (or inconclusive) cases further imaging as MRI could be helpful to avoid negative appendectomy.

BACKGROUND: Exact lymph node staging is essential in rectal cancer therapy. OBJECTIVE: The aim of the study was to assess the impact of intra-arterial indigo carmine injection after transanal total mesorectal excision on the number of retrieved lymph nodes. DESIGN: This was a retrospective, nonrandomized study. SETTINGS: The study was conducted at a tertiary hospital by a multidisciplinary team. PATIENTS: Patients who underwent transanal total mesorectal excision for suspected rectal cancer between 2013 and 2019 were included. INTERVENTIONS: Rectal cancer specimens received ex vivo intra-arterial indigo carmine injection to stain lymph nodes. MAIN OUTCOME MEASURES: Outcome measures included the number of retrieved lymph nodes with or without staining. RESULTS: Specimens of 189 patients were analyzed, of which 108 (57.1%) were stained with indigo carmine. A mean of 19.8 ± 6.1 lymph nodes was identified in stained samples compared to 16.0 ± 4.9 without staining ( p < 0.001). Multivariable analysis showed that 3.2 additional lymph nodes were found in stained specimens (95% CI: 1.0 to 5.3; p = 0.02). In stained specimens the adequate lymph node count (≥12) was increased in univariable (odds ratio: 3.24, 95% CI: 1.13 to 10.65; p = 0.03) but not in multivariable analysis. Indigo carmine injection had no effect on the number of positive lymph nodes or the nodal stage. Chemoradiotherapy reduced the lymph node count by 2.5 ( p = 0.008). After staining, 95.0% of patients with chemoradiotherapy had ≥12 lymph nodes retrieved. The median follow-up of patients was 24.2 months with a local recurrence rate of 3.3%. LIMITATIONS: The study is limited by its retrospective design and the nonrandomized allocation. CONCLUSIONS: Ex vivo intra-arterial indigo carmine injection increases the number of isolated lymph nodes after transanal total mesorectal excision regardless of neoadjuvant chemoradiotherapy. Indigo carmine injection is not associated with nodal upstaging or an increased number of tumor-positive lymph nodes. See Video Abstract at http://links.lww.com/DCR/B839 . ESTADIFICACIN AVANZADA DE LOS GANGLIOS LINFTICOS CON INYECCIN INTRAARTERIAL EX VIVO,DE NDIGO CARMN,DESPUS DE LA ESCISIN TOTAL DEL MESORRECTO POR VA TRANSANAL PARA CNCER DE RECTO UN ESTUDIO DE COHORTE RETROSPECTIVO: ANTECEDENTES:La estadificación exacta de los ganglios linfáticos es esencial en la tratamiento del cáncer de recto.OBJETIVO:El objetivo del estudio fue evaluar el impacto de la inyección intraarterial de índigo carmín después de la escisión total del mesorrecto por vía transanal con relación al número de ganglios linfáticos recuperados en el espécimen quirúrgico..DISEÑO:Estudio retrospectivo no aleatorizado.AJUSTE:El estudio se llevó a cabo en un hospital de tercer nivel por un equipo multidisciplinario.PACIENTES:Pacientes a quienes se les practicó escisión total del mesorrecto por vía transanal por sospecha de cáncer de recto entre 2013 y 2019.INTERVENCIONES:Al espécimen quirúrgico que se obtuvo, se le practicó inyección intraarterial ex vivo, de índigo carmín para teñir los ganglios linfáticos.PRINCIPALES MEDIDAS DE RESULTADO:El número de ganglios linfáticos recuperados con o sin tinción.RESULTADOS:Se analizaron muestras de 189 pacientes, de los cuales 108 (57,1%) fueron teñidos con índigo carmín. Se identificó una media de 19,8 ± 6,1 ganglios linfáticos en las muestras teñidas en comparación con 16,0 ± 4,9 sin tinción ( p < 0,001). El análisis multivariado mostró que se encontraron 3.2 ganglios linfáticos adicionales en las muestras teñidas (intervalo de confianza del 95%: 1,0 a 5,3; p = 0,02). En las muestras teñidas, el recuento adecuado de ganglios linfáticos (≥12) aumentó en el análisis univariado (razón de posibilidades: 3,24, intervalo de confianza del 95%: 1,13 a 10,65; p = 0,03) pero no en el multivariado. La inyección de índigo carmín no tuvo ningún efecto sobre el número de ganglios linfáticos positivos o el estadio ganglionar. La quimiorradioterapia redujo el recuento de ganglios linfáticos en 2,5 ( p = 0,008). Después de la tinción, en el 95,0% de los pacientes con quimiorradioterapia se recuperaron ≥12 ganglios linfáticos. La mediana de seguimiento de los pacientes fue de 24,2 meses con una tasa de recurrencia local del 3,3%.LIMITACIONES:El estudio está limitado por su diseño retrospectivo y la asignación no aleatoria.CONCLUSIONES:La inyección ex vivo de índigo carmín intraarterial aumenta el número de ganglios linfáticos aislados después de la escisión total del mesorrectal por vía transanal a pesar de la quimiorradioterapia neoadyuvante. La inyección de índigo carmín no se asocia con un aumento del estadio de los ganglios ni con un mayor número de ganglios linfáticos positivos para tumor.

BACKGROUND: Complete and correct documentation of diagnosis and procedures is essential for adequate health provider reimbursement in diagnosis-related group (DRG) systems. The objective of this study was to investigate whether daily monitoring and semiautomated proposal optimization of DRG coding (precoding) is associated with higher reimbursement per hospitalization day. MATERIALS AND METHODS: This parallel-group, unblinded, randomized clinical trial randomized patients 1:1 into intervention (precoding) and control groups. Between June 12 and December 6, 2019 all hospitalized patients (1566 cases) undergoing elective or emergency surgery at the department of surgery in a Swiss hospital were eligible for this study. By random sample selection, cases were assigned to the intervention (precoding) and control groups. The primary outcome was the total reimbursement, divided by the length of stay. RESULTS: Of the 1205 randomized cases, 1200 (precoding group: 602) remained for intention-to-treat, and 1131 (precoding group: 564) for per-protocol analysis. Precoding increased reimbursement per hospitalization day by 6.5% (160 US dollars; 95% confidence interval 31 to 289; P = 0.015). In a regression analysis patients hospitalized 7 days or longer, precoding increased reimbursement per day by 10.0% (246 US dollars; 95% confidence interval -12 to 504; P = 0.021). More secondary diagnoses (mean [SD]: 5.16 [5.60] vs 4.39 [5.34]; 0.77; 95% confidence interval 0.15 to 1.39; P = 0.015) and nonsurgical postoperative complications (mean [SD]: 0.68 [1.45] vs 0.45 [1.12]; 0.23; 95% confidence interval 0.08 to 0.38; P = 0.002) were documented by precoding. No associated was observed regarding the length of stay, total reimbursement, or case mix index. The mean (SD) precoding time effort was 37 (27) minutes per case. CONCLUSION: Physician-led precoding increases DRG-based reimbursement. Precoding is time consuming and should be focused on cases with a longer hospital stay to increase efficiency.

AIM: This study assessed the impact of a prophylactic, 3D funnel-shaped intraperitoneal mesh on the rate of parastomal hernia after abdominoperineal rectum resection with permanent end colostomy. METHODS: Data from 76 patients receiving permanent end colostomy after abdominoperineal rectum resection between 2013 and 2018 were collected retrospectively. Occurrences of parastomal hernia and reoperation rate due to parastomal hernia in patients with and without a prophylactic mesh were compared by univariate, multivariate, and propensity score-adjusted analyses. RESULTS: Twenty-two (28.9%) of the 76 included patients received a prophylactic mesh. The mean follow-up was 39.3 ± 23.8 months. Mesh implantation reduced the incidence of parastomal hernia to 9.1% (n = 2) compared to 42.6% (n = 23) in patients without a prophylactic mesh. The propensity score-adjusted hazard ratio (HR) was 0.14 (95% confidence interval (CI): 0.04-0.48, p = 0.001). No reoperations due to parastomal hernia were needed in patients who received a prophylactic mesh, while nine patients without mesh (16.7%) required parastomal hernia repair (HR = 0.09, 95% CI: 0.00-1.76, p = 0.015). Mesh implantation was not associated with increased short-term morbidity (Clavien-Dindo grade > 2, 31.8% vs. 40.7%, p = 0.468) or 30-day mortality (4.5% vs. 3.8%, p = 1.000). CONCLUSIONS: Prophylactic implantation of a 3D funnel-shaped intraperitoneal mesh is a safe and effective method to prevent parastomal hernia in patients requiring permanent end colostomy. Mesh placement significantly reduces reoperations due to parastomal hernia.

INTRODUCTION: Pressurized intraperitoneal aerosol chemotherapy (PIPAC) is a treatment option for patients with peritoneal metastases. We evaluated the current status of ongoing prospective clinical trials investigating PIPAC to provide an overview and predict trends in this field. METHODS: All 367,494 records of clinical trials registered at ClinicalTrials.gov were searched for trials dealing with PIPAC. Active or unpublished trials were further analyzed. RESULTS: In total, 22 clinical trials were identified and selected for further analyses. Most trials had a single-arm design and were phase I or II. No phase III trials were registered. Academic centers were recorded as primary sponsors in the majority of trials (63.6%). Every year, between 2 and 5 new trials were initiated. In 17 trials (81.8%), PIPAC was used in a palliative setting only, 2 trials performed PIPAC in a neoadjuvant setting, and 2 trials performed PIPAC in an adjuvant setting. Six different drugs (doxorubicin, cisplatin, oxaliplatin, nab-paclitaxel, 5-fluorouracil, and docetaxel) were used in these clinical trials. Most trials investigated the efficacy (n = 15) or safety (n = 7) of PIPAC therapies. CONCLUSIONS: The results of ongoing clinical trials will bring specific information on indications for PIPAC as well as the impact of PIPAC on quality of life and overall survival.

BACKGROUND: Postoperative aspiration pneumonia is a feared complication contributing significantly to postoperative morbidity and mortality. Over decades, there has been little progress in reducing incidence and mortality of postoperative aspiration pneumonia. Here, we assessed risk factors for postoperative aspiration pneumonia in general and abdominal surgery patients. METHODS: Patients undergoing surgery between January 2012 and December 2018 were included in this exact matched and weighted case-control study. Data from a prospectively acquired clinical database were retrospectively analyzed. RESULTS: Among 23,647 patients undergoing 32,901 operations, 144 (0.44%, 95% Confidence Interval: 0.37%-0.52%) cases of postoperative aspiration pneumonia were identified. Ninety-day mortality was 27.8% (n = 40). Major risk factors for postoperative aspiration pneumonia were emergency surgery in patients with prolonged preoperative fasting (>6 hours; odds ratio: 3.25, 95% confidence interval: 1.46-7.26; P < .001), older age with increasing risk in octogenarians compared to seniors (65-80 years: n = 69; odds ratio 5.23, 95% confidence interval: 2.18-12.51; >80 years: n = 50; odds ratio 13.72, 95% confidence interval: 4.94-38.09; P < .001), American Society of Anesthesiologists scores >II (American Society of Anesthesiologists III: n = 90; odds ratio 3.38, 95% confidence interval: 1.08-16.01; American Society of Anesthesiologists IV/V: n = 18; odds ratio 5.20, 95% confidence interval: 1.48-27.61; P < .001), and body mass index <18 kg/m2 (n = 9; odds ratio: 2.53; 95% confidence interval: 1.04-6.11; P = .029). Laparoscopies (odds ratio 0.45, 95% confidence interval: 0.23-0.88; <0.001) and female sex were associated with a decreased risk for postoperative aspiration pneumonia (odds ratio 0.40, 95% confidence interval: 0.23-0.69; P < .001). CONCLUSION: Preventive measures to reduce postoperative aspiration pneumonia should focus on older patients with American Society of Anesthesiologists scores ≥III undergoing open surgery. Cachectic patients and patients undergoing emergency surgery with prolonged preoperative fasting require increased attention. Laparoscopy was associated with a lower risk for postoperative aspiration pneumonia and should be preferred whenever appropriate.

BACKGROUND: Patients with gastroesophageal reflux disease (GERD) often suffer greatly from their symptoms. The aim of this study was to determine if there is a difference in quality of life and gastrointestinal symptom complexes between patients with purely functional complaints and patients with objective GERD. MATERIAL AND METHODS: We included all patients with typical reflux symptoms, who had a GERD examination in 2017 at our department. All patients underwent high resolution manometry, 24-h-pH-metry impedance measurement and gastroscopy. Quality of life was assessed using the Gastrointestinal Quality of Life Index (GIQLI) and gastrointestinal symptoms were rated by a symptom checklist (SCL), assessing the severity and intensity of 14 different symptoms. Based on the results of the 24-h-pH-metry impedance measurement, patients were divided into 2 groups: patients with functional reflux symptoms and patients with true GERD. These two groups were compared. RESULTS: Complete data were available in 162 patients, of whom 86 (52.2%) were objectively suffering from reflux (DeMeester score mean: 37.85; SD ± 29.11) and 76 (46.1%) had a normal DeMeester score (Mean: 7.01; SD ± 4.09). No significant difference in quality of life was found between the two groups (mean GIQLI of GERD patients: 94.81, SD ± 22.40, and mean GIQLI of patients with functional reflux symptoms: 95.26, SD ± 20.33, p = 0.988). Furthermore, no significant difference could be found in the evaluated symptoms (mean general SCL score of GERD patients: 46.97; SD ± 29.23; patients with functional reflux symptoms: 48.03; SD ± 29.17, p = 0.827). CONCLUSION: Patients with functional complaints suffer just as much from their symptoms as patients with objectively diagnosed GERD. Differentiation between gastroesophageal reflux disease and functional reflux symptoms is only possible by means of functional diagnostic testing.

PURPOSE: Only a small fraction of resectable gallbladder cancer (GBC) patients receive a thorough lymphadenectomy. The aim of this systematic review and meta-analysis was to investigate the effect of lymphadenectomy on survival in GBC surgery. METHODS: On May 19, 2019, MEDLINE, EMBASE, and the Cochrane Library were searched for English or German articles published since 2002. Studies assessing the effect of lymphadenectomy on survival in GBC surgery were included. Fixed effect and random effects models were used to summarise the hazard ratio (HR). RESULTS: Of the 530 identified articles, 18 observational studies (27,570 patients, 10 population-based, 8 cohort studies) were reviewed. In the meta-analysis, lymphadenectomy did not show a significant benefit for T1a tumours (n = 495; HR, 1.37; 95%CI, 0.65-2.86; P = 0.41). Lymphadenectomy showed a significant survival benefit in T1b (n = 1618; HR, 0.69; 95%CI, 0.50-0.94; P = 0.02) and T2 (n = 6204; HR, 0.68; 95%CI, 0.56-0.83; P < 0.01) tumours. Lymphadenectomy improved survival in the 2 studies assessing T3 tumours (n = 1961). A conclusive analysis was not possible for T4 tumours due to a low case load. Among patients undergoing lymphadenectomy, improved survival was observed in patients with a higher number of resected lymph nodes (HR, 0.57; 95%CI, 0.45-0.71; P < 0.01). CONCLUSIONS: Regional lymphadenectomy improves survival in T1b to T3 GBC. A minimum of 6 retrieved lymph nodes are necessary for adequate staging, indicating a thorough lymphadenectomy. Patients with T1a tumours should be evaluated for lymphadenectomy, especially if lymph node metastases are suspected.

BACKGROUND: The impact of sound-activated noise meters to decrease the noise level in the operating room is not clear. The aim of this study was to determine whether a sound-activated, visual noise meter would decrease noise levels, decrease postoperative morbidity, and improve surgeons' feelings of well-being. METHODS: This prospective, single-center study proceeded in 2 phases. First, sound levels were compared during a 6-month period with noise measurement only and without a visual feedback function. Second, we conducted a subsequent 6-month phase with noise meters providing direct feedback. Surgeon disturbance during the operation was assessed by a questionnaire after each procedure. RESULTS: Of the 664 procedures included in this analysis, 447 (67.3%) were in phase 1 and 217 (32.7%) in phase 2. The noise levels in the operating room were decreased by 3.8 dB(A) from 54.6 ± 4.5 dB(A) in phase 1 to 50.8 ± 2.8 dB(A) in phase 2 after intervention with the feedback device (P < .001). During the procedures, there was an increase of 0.7 dB(A) (P < .001), with mean noise levels of 53.5 dB(A) at the beginning of the procedures and 54.2 dB(A) at the end. There was a correlation between the disturbance of the surgeon and the noise level (P < .001). CONCLUSION: The application of a visual noise warning device in an operating room decreased both the noise levels and surgeon stress and may offer sustained decreases in ambient and peak sound levels, potentially leading to improved quality outcomes in visceral surgery.

PURPOSE: The aim of this study was to assess the effect of lymphadenectomy on survival in T1/T2 gallbladder cancer (GBC). METHODS: In this retrospective cohort study, patients undergoing surgery for T1/T2 GBC from 2004 to 2014 were identified in the Surveillance, Epidemiology, and End Results database. The effect of lymph node excision (LNE) on survival was assessed using Cox regression and propensity score methods. RESULTS: A total of 2112 patients were identified: 11.4% had T1a, 18.5% T1b, and 70.1% had T2 tumors. Mean follow-up was 31.3 months. In 48.8% of patients, LNE was performed with a mean of 3.6 ± 4.3 nodes retrieved. Cancer-specific 5-year survival for T1 and T2 stages combined was 49.6% (95% confidence interval (CI), 45.9-53.6%) without LNE compared to 56.2% (95% CI, 52.4-60.4%) if LNE was performed (hazard ratio (HR), 0.75; 95%CI, 0.64-0.86, P < 0.001). Propensity score analyses for both stages combined confirmed this survival benefit with an HR of 0.67 (95% CI, 0.55-0.80) for the LNE group (P < 0.001). Stratified for tumor stages, LNE had no significant effect on cancer-specific survival in T1a (HR, 1.80 (95% CI, 0.76-4.26), P = 0.185) or T1b tumors (HR, 0.95 (95% CI, 0.57-1.58), P = 0.844), whereas it persistently revealed an advantage for patients with T2 tumors (HR 0.68 (95% CI, 0.55-0.83, P < 0.001). No correlation between the number of retrieved lymph nodes and the N+ rate was found (P = 0.134). CONCLUSIONS: LNE is associated with improved survival in T2 GBC. No significant survival benefit was observed in T1a and T1b tumors. The retrieval of even a few lymph nodes reliably predicts the nodal status, which might assist in patient selection for re-resection in T1 GBC.

BACKGROUND/AIMS: The aim of this study was to evaluate the sustainability of sacral neuromodulation (SNM) success in patients with fecal incontinence (FI) and/or constipation. METHODS: This is a retrospective analysis of a prospective database of patients who received SNM therapy for FI and/or constipation between 2006 and 2015. Success rates, complications and reintervention rates were assessed after up to 10 years of follow-up. RESULTS: Electrodes for test stimulation were implanted in 101 patients, of whom 79 (78.2%) received permanent stimulation. The mean follow-up was 4.4 ± 3.0 years. At the end of follow-up, 57 patients (72.2%) were still receiving SNM. The 5-year success rate for FI and isolated constipation was 88.2% (95% confidence interval [CI], 80.1-97.0%) and 31.2% (95% CI, 10.2-95.5%), respectively (P ï¼ 0.001). In patients with FI, involuntary evacuations per week decreased ï¼ 50% in 76.1% of patients (95% CI, 67.6-86.2%) after 5 years. A lead position at S3 was associated with an improved outcome (P = 0.04). Battery exchange was necessary in 23 patients (29.1%), with a median battery life of 6.2 years. Reinterventions due to complications were necessary in 24 patients (30.4%). For these patients, the 5-year success rate was 89.0% (95% CI, 75.3-100.0%) compared to 78.4% (95% CI, 67.2-91.4%) for patients without reintervention. CONCLUSIONS: SNM offers an effective sustainable treatment for FI. For constipation, lasting success of SNM is limited and is thus not recommended. Reinterventions are necessary but do not impede treatment success.
RESUMEN
OBJECTIVE: The aim of this study was to assess the influence of regional lymph node (RLN) retrieval on stage migration and survival in pancreatic cancer. METHODS: A total of 7685 stage I and II pancreatic cancer patients were identified in the Surveillance, Epidemiology, and End Results database in 2004-2011. The impact of RLN was assessed using Cox regression, propensity score methods, and joinpoint regression. RESULTS: In 3079 patients, 1 to 10 RLNs were retrieved; in 2799 patients, 11 to 19 RLNs, and in 1807 patients, 20+ RLNs. The rate of node-positive pancreatic cancer increased with the number of retrieved RLN. This trend continued beyond 10 retrieved RLN (P < 0.001). In unadjusted analysis, retrieval of RLN did not influence survival (P = 0.178). When adjusting for significant bias in staging variables (P < 0.001), retrieval of 20+ RLNs compared to 11 to 19 RLNs was associated with an increased survival in node-negative (hazard ratio, 0.78; 95% confidence interval, 0.62-0.98; P = 0.033) and node-positive cancer (hazard ratio, 0.83; 95% confidence interval, 0.74-0.93; P = 0.002). CONCLUSIONS: This population-based propensity score-adjusted investigation demonstrated that more retrieved RLNs in pancreatic cancer decreases the rate of stage migration and improves the oncological outcome in node-negative and positive cancer. Contradictory results may be explained by a bias in the cancer characteristics for a different extent of RLN retrieval.

Objective: In the treatment of patients with alcohol dependence it is next to physical detoxification under protected conditions to promoting abstinence motivation. Further the need of crisis interventions is derived from the clinical practise. To be able to become fairer to all groups of treatment as well as the different demands, the addiction admission station was restructured. Methods: Pre-post-evaluation. Results: It was found that the door was closed up significantly less often after the restructuring. In the residence time structure an increase appeared in the descriptive values with the more than 7-day stays. Conclusions: It is to be able to hold successfully the optional closed door highly significantly more often open.

PURPOSE: Perineal stapled prolapse resection (PSP) has been described as a new surgical treatment for external rectal prolapse in 2008. Short-term and midterm results acknowledged PSP as a safe, fast and simple procedure for high-risk patients. This study aims to assess long-term results after PSP. METHODS: All patients who underwent PSP from 2007 to 2015 were analyzed retrospectively. Data was gathered from medical records and operative reports and by interviews with the general practitioner or the patient. RESULTS: Indication for PSP was provided in 64 cases. One procedure had to be changed to an Altemeier's and another to a laparoscopic rectopexy. The median age was 79.9 years (range 25.9-97.5). Spinal anaesthesia was used in 19 patients. The median operation time was 32.5 min (range 25-51.2). There was no mortality. One patient had to be reoperated. All other complications were minor. The median hospital stay was 6.0 days (range 2-23). Median follow-up of patients alive was 6.0 years (range 0.2-8.4). The 5-year recurrence-free survival rate for primary prolapse was 70.1 % compared to 34.3 % for recurrent prolapses (p = 0.048). Further positive prognostic factors were specimen length over 8 cm and lack of preoperative obstructed defecation syndrome. Faecal incontinence was remedied in 18, and new onset was recorded in 6 patients (significant incontinence rate reduction (p = 0.025)). CONCLUSION: Due to low morbidity and the possibility of spinal anaesthesia, PSP is suitable for frail patients. The recurrence rate for primary prolapse is similar to alternative perineal procedures like Delorme's and Altemeier's, but inferior to the laparoscopic techniques.

BACKGROUND: Whereas the poor prognosis of signet ring cell adenocarcinomas of the appendix is well known, the significance of mucinous histology remains unclear. The aim of this population-based study was to evaluate if mucinous histology is an independent prognostic factor in appendiceal adenocarcinomas. METHODS: Patients with stage I-III adenocarcinoma of the appendix who underwent surgery between 2004 and 2012 were identified in the Surveillance, Epidemiology, and End Results database. Overall survival (OS) and cancer-specific survival (CSS) were assessed using risk-adjusted Cox proportional hazards regression models and propensity score methods. RESULTS: Overall, 980 patients with appendix cancer were included, of which 449 (45.8 %) had a mucinous histology. In an unadjusted analysis, the 5-year OS and CSS in patients with a mucinous adenocarcinoma (MC) was 76.8 % (95 % confidence interval (95 %CI): 72.1-81.7 %) and 81.0 % (95 %CI: 76.6-85.6 %), respectively, compared with 70.0 % (95 %CI: 65.1-75.3 %) and 76.2 % (95 %CI: 71.5-81.2 %) in patients with non-mucinous adenocarcinoma (NMC) (P = 0.082 and P = 0.368). In multivariable analysis, no impact on survival was observed for OS (HR = 1.22, 95 %CI: 0.89-1.68, P = 0.208) and CSS (HR = 1.21, 95 %CI: 0.84-1.74, P = 0.296). After propensity score matching, nearly identical survival rates were observed (OS: HR = 1.03, 95 %CI: 0.71-1.49, P = 0.881 and CSS: HR = 1.05, 95 %CI: 0.70-1.59, P = 0.803). CONCLUSIONS: The present population-based, propensity score matched analysis shows that mucinous histology does not affect survival in stage I-III appendiceal adenocarcinoma patients. Therefore, the same treatment strategies can be applied for patients with NMC and MC of the appendix.

BACKGROUND: Local resection of early-stage rectal cancer significantly reduces perioperative morbidity compared with radical resection. Identifying patients at risk of regional lymph node metastasis (LNM) is crucial for long-term survival after local resection. METHODS: Patients after oncological resection of T1 rectal cancer were identified in the Surveillance, Epidemiology, and End Results register 2004-2012. Potential predictors of LNM and its impact on cancer-specific survival were assessed in logistic and Cox regression with and without multivariable adjustment. RESULTS: In total, 1593 patients with radical resection of T1 rectal cancer and a minimum of 12 retrieved regional lymph nodes were identified. The overall LNM rate was 16.3 % (N = 260). A low risk of LNM was observed for small tumor size (P = 0.002), low tumor grade (P = 0.002) and higher age (P = 0.012) in multivariable analysis. The odds ratio for a tumor size exceeding 1.5 cm was 1.49 [95 % confidence interval (CI) 1.06-2.13], for G2 and G3/G4 carcinomas 1.69 (95 % CI 1.07-2.82) and 2.72 (95 % CI 1.50-5.03), and for 65- to 79-year-old and over 80-year-old patients 0.65 (95 % CI 0.43-0.96) and 0.39 (95 % CI 0.18-0.77), respectively. Five-year cancer-specific survival for patients with LNM was 90.0 % (95 % CI 85.3-95.0 %) and for patients without LNM 97.1 % (95 % CI 95.9-98.2 %, hazard ratio = 3.21, 95 % CI 1.82-5.69, P < 0.001). CONCLUSIONS: In this population-based analysis, favorable cancer-specific survival rates were observed in nodal-negative and nodal-positive T1 rectal cancer patients after primary radical resection. The predictive value of tumor size, grading and age for LNM should be considered in medical decision making about local resection.

OBJECTIVES: Previous studies indicate high rates of childhood trauma experiences as well as of mental disorders among prisoners. In this study, we investigate (1) the prevalence of different kinds of early traumatic experiences in female and male incarcerated prisoners, (2) their associations with mental disorders, and (3) their associations with characteristics of criminal behaviors. METHOD: The Childhood Trauma Questionnaire, Structured Clinical Interviews for DSM-IV Axis I and II Disorders, and Symptom Checklist-90-Revised (current psychopathology) were administered, and the subjects' criminal and arrest histories were obtained. All assessments were performed between May 1, 2002, and June 1, 2003. RESULTS: Comparable sample groups of 63 incarcerated women and 76 men participated. Apart from low rates of short stay prisoners and foreign nationals, the sample was comparable with all prisoners in North-Rhine Westfalia (largest state in Germany). A history of at least 1 type of moderate or severe childhood trauma was reported by 50.4% of the prisoners. In 86.3%, >/= 1 lifetime Axis I disorder was found (current, 83.5%), and a high mean number of comorbid diagnoses was found (mean +/- SD lifetime = 3.6 +/- 3.3, current = 2.9 +/- 2.7). In 53.2% of the sample, at least 1 Axis II (personality) disorder was diagnosed. The numbers of comorbid Axis I lifetime and current disorders as well as the number of lifetime Axis II disorders were significantly (p < .001) associated with the severity of childhood trauma history, indicating a dose-response relationship. Negative associations were observed between the severity of childhood trauma and age at first offense. CONCLUSION: Severity of childhood trauma experiences is associated with the presence and number of Axis I and Axis II mental disorders and may play a crucial role in the development of these disorders.
