RESUMO
BACKGROUND: Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy is a curative treatment for selected patients with peritoneal surface malignancy. Reaching actual outcomes benchmarks is challenging given the complex nature of peritoneal surface malignancy surgery. The aim of this study was to assess how the benchmarks for morbidity and oncologic outcome can be reached at a newly established program for cytoreductive surgery and hyperthermic intraperitoneal chemotherapy. METHODS: Building on existing institutional experience in complex abdominal surgery and interdisciplinary ovarian cancer treatment, a peritoneal surface malignancy center for cytoreductive surgery and hyperthermic intraperitoneal chemotherapy was established at the Medical University of Vienna using a structured mentoring process. This is a retrospective analysis of the first 100 consecutive patients. Morbidity and mortality were assessed using the Clavien-Dindo classification, and oncologic outcomes using overall survival. RESULTS: Major morbidity and mortality were 26% and 3%, and median overall survival was 49.0 months. In patients with colorectal peritoneal metastases, the median overall survival was 35.1 months (all colorectal peritoneal metastases patients) and 48.8 months in the subgroup with Peritoneal Surface Disease Severity Score ≤3. No median overall survival could be calculated in patients with low-grade appendiceal mucinous neoplasms, appendiceal adenocarcinoma, or peritoneal mesothelioma due to >50% of patients being alive at the end of follow-up. CONCLUSION: We show that the current morbidity and oncological outcomes benchmarks can be reached within the first 100 cases of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy at a newly established peritoneal surface malignancy center. Previous institutional experience in complex abdominal surgery and a structured mentoring process are key factors in achieving this goal.

BACKGROUND: Correct tack placement at the sacral promontory for mesh fixation in ventral mesh rectopexy is crucial to avoid bleeding, nerve dysfunction, and spondylodiscitis. OBJECTIVE: The present cadaver study was designed to assess the true location of tacks after mesh fixation during laparoscopic ventral mesh rectopexy in relation to vascular and nerve structures and bony landmarks. DESIGN: This was an interventional cadaver study. SETTING: This study was conducted after laparoscopic mesh fixation detailed pelvic dissection was performed following a standardized protocol. In addition, 64-row multidetector computed tomography was conducted to further define lumbosacral anatomy and tack positioning. PATIENTS: Eighteen fresh cadavers (10 female, 8 male) were included in this study. MAIN OUTCOME MEASURES: True tack position and vascular and neuronal involvement served as outcome measures. RESULTS: A total of 52 tacks were deployed (median 3, range 2-3 tacks). Median tack distance to the midsacral promontory was 16.1 mm (0.0-54.2). Only a total of 22 tacks (42.3%) were found on the right surface of the S1 vertebra, correlating with the planned deployment area. In 7 cadavers (38.8%), all tacks were deployed on the planned deployment area. The median distance to the major vessels was 10.5 mm (0.0-35.0), which was the internal iliac artery in half of the cases. Median distance of tacks to the right ureter was 32.1 mm (7.5-46.1). Neither major vessels nor the ureter was injured. Dissection of the hypogastric plexus was undertaken in 14 cadavers, and in each cadaver, tacks affected the hypogastric nerve plexus. LIMITATIONS: This study was limited by the moderate number of cadavers. CONCLUSIONS: Tack placement showed significant variation in our specimen, emphasising the need for reliable anatomic landmarks and sufficient exposure during ventral mesh rectopexy. Hypogastric nerve plexus involvement is common, thus detailed functional assessment after surgery is required. It also points out the importance of cadaver studies before implementing new surgical techniques into clinical practice. See Video Abstract at http://links.lww.com/DCR/B827. FIJACIN LAPAROSCPICA DE MALLA SACRA PARA RECTOPEXIA VENTRAL IMPLICACIONES CLNICAS DE UN ESTUDIO SOBRE CADAVERS: ANTECEDENTES:La colocación correcta de la tachuela en el promontorio sacro para la fijación de la malla en la rectopexia con malla ventral es crucial para evitar hemorragias, disfunción nerviosa y espondilodiscitis.OBJETIVO:El presente estudio en cadáveres fue diseñado para evaluar la verdadera ubicación de las tachuelas después de la fijación de la malla durante la rectopexia laparoscópica con malla ventral en relación con las estructuras vasculares y nerviosas y los puntos de referencia óseos.DISEÑO:Estudio intervencionista de cadáveres.AJUSTE:Después de la fijación laparoscópica de la malla, se realizó una disección pélvica detallada siguiendo un protocolo estandarizado. Además, se realizó una tomografía computarizada multidetector de 64 cortes para definir mejor la anatomía lumbosacra y la posición de la tachuela.PACIENTES:Se incluyeron en este estudio dieciocho cadáveres frescos (10 mujeres, 8 hombres).PRINCIPALES MEDIDAS DE RESULTADO:Posición real de tachuela y compromiso vascular y neuronal.RESULTADOS:Se utilizaron un total de 52 tachuelas (mediana 3, 2-3 tachuelas). La distancia media de tachuela al promontorio sacro medio fue de 16,1 mm (0,0-54,2). Solo se encontraron un total de 22 tachuelas (42,3%) en la superficie derecha de la vértebra S1, correlacionándose con el área planificada. En siete cadáveres (38,8%) todas las tachuelas se utilizaron en el área de planificada. La distancia media a los vasos principales fue de 10,5 mm (0,0-35,0), que era la arteria ilíaca interna en la mitad de los casos. La distancia media de las tachuelas al uréter derecho fue de 32,1 mm (7,5-46,1). No se lesionó ni los grandes vasos ni el uréter. La disección del plexo hipogástrico se realizó en 14 cadáveres y en cada cadáver, las tachuelas afectaron el plexo nervioso hipogástrico.LIMITACIONES:Número moderado de cadáveres incluidos en el estudio.CONCLUSIONES:La colocación de tachuelas mostró una variación significativa en nuestra muestra, enfatizando la necesidad de puntos de referencia anatómicos confiables y una exposición suficiente durante la rectopexia con malla ventral. La afectación del plexo nervioso hipogástrico es común, por lo que se requiere una evaluación funcional detallada después de la cirugía. También destaca la importancia de los estudios sobre cadáveres antes de implementar nuevas técnicas quirúrgicas en la práctica clínica. Consulte Video Resumen en http://links.lww.com/DCR/B827.

The aim of this study is the evaluation of three selected osseous pelvic features in modern anatomical specimen - the sacral preauricular extension, the preauricular sulcus and pits on the dorsal side of the pubic bone laterally to the symphysis. The specificity and significance of these features are under debate and their genesis is largely unclear. Descriptive data of specific soft tissue structures surrounding the anterior sacroiliac joint gap and the pubic symphysis were generated by assessing 20 fresh pelves and 12 embalmed hemipelves from human body donors. Computed tomography (CT) was performed on all specimens and three-dimensional (3D) surface models were generated and analysed. Afterwards, all the specimens underwent anatomical dissection and finally maceration. During dissection, it became apparent that the anterior sacroiliac ligament, due to its position, shape and potential impact on the sacroiliac joint and adjacent osseous structures, requires a detailed analysis of its dimension. The most promising result, in terms of the sacral preauricular extension, was that the measurements of the triangular part of the anterior sacroiliac ligament were significantly longer in females than in males. Pelvic floor muscle fibres and fascial parts were directly connected to this ligament in some specimens, which is an important starting point for a larger in-depth study. The evaluation of the anatomic structures in connection to dorsal pitting refutes the assumption that the pelvic floor muscles or fasciae could exert influence on its formation. A histological evaluation of the ligaments of the pubic symphysis, especially the dorsal pubic ligament, would be expedient to clarify the etiology of this feature.

BACKGROUND: The rate of restoration of intestinal continuity after colonic resection and stoma creation in patients with Crohn's disease has not been well-documented in the era of biologics. Thus, the incidence of restoration of intestinal continuity since the introduction of biological drugs was assessed. METHODS: Consecutive patients (nâ¯= 43) who underwent colonic resection with ileostomy or colostomy formation for Crohn's disease at a single tertiary referral center between 2002 and 2014 were identified. Data from individual chart review were analyzed retrospectively. Patients were personally contacted for follow-up. RESULTS: Of the 43 patients 8 (18.4%) had a proctectomy leaving 35 patients (81.4%) with the rectum preserved. Of the 30 patients qualifying for final analysis restoration of bowel continuity was finally achieved in 10 patients (33.3%). Permanent stoma rates were comparable in the group of patients with and without biological therapy after surgery (64.3% vs. 60%). The median follow-up period was 7 years (range 3-15 years). Of the patients 20 suffered from perianal disease involvement (66.7%), which was associated with a higher rate of permanent stoma (nâ¯= 16/20, 80%) in contrast to patients without perianal disease (nâ¯= 4/10, 40%, pâ¯= 0.045). CONCLUSION: The overall incidence of stoma formation was low for patients with Crohn's disease; however, once a stoma is created the chance of ending up with a permanent stoma is high even in the era of biologics. Despite the use of new therapeutic agents perianal disease increases the risk of a permanent stoma.

BACKGROUND: Recent studies support the use of mechanical bowel preparation and/or oral antibiotic prophylaxis in patients operated on for Crohn's disease (CD); however, data are scarce, especially for laparoscopic surgery. Therefore, this study was carried out to investigate the effect of laparoscopic surgery on complication rates in patients not undergoing standardized bowel preparation but single shot antibiotics. METHODS: In this study 255 consecutive patients who underwent a laparoscopic intestinal resection for CD at a tertiary referral center between 1997 and 2014 were retrospectively analyzed. Superficial surgical site infections (SSI), organ/space infections and ileus were recorded and grouped according to the type of resection (colorectal vs. small intestine⯱ ileocecal). RESULTS: The baseline characteristics of the groups were comparable. Colorectal resections showed a significantly increased risk of organ/space infection (4.6% in small intestine⯱ ileocecal vs. 14.3% in colorectal resections pâ¯= 0.039). The superficial SSI rate was low in both groups (1.8% in small intestine⯱ ileocecal resection vs. 0% in colorectal resections, pâ¯= 1.000). Univariate binary logistic regression analysis revealed a statistically significant influence of duration of surgery (pâ¯= 0.001) and type of resection (pâ¯= 0.031) on organ/space infection. In multivariate analysis, only duration of surgery (OR 1.111, 95% CI 1.026-1.203 for every 10â¯min, pâ¯= 0.009) remained significant for postoperative organ/space infections. CONCLUSIONS: Single-shot antibiotic therapy without bowel preparation is safe in patients undergoing minimally invasive surgery and was associated with a low number of complications; however, organ/space infections were more common if colorectal resections were performed. Therefore, combined bowel preparation might be beneficial when the (sigmoid) colon or rectum are involved.

PURPOSE: Little is known about the perioperative dynamic of albumin and its effect on surgical outcome in Crohn's disease. Thus, we aimed to assess postoperative changes of albumin levels and their potentially predictive role for complications after laparoscopic intestinal resections. METHODS: We identified 182 patients who underwent laparoscopic intestinal resection for symptomatic Crohn´s disease between 2000 and 2014 for this retrospective cohort study. Pre- and postoperative serum albumin levels (within 4 days) were recorded retrospectively and proportional postoperative reduction (delta (Δ) albumin) was calculated. Complications were defined according to the Clavien-Dindo classification. Univariate and multivariate analysis describing an eventful postoperative course were conducted. RESULTS: Complications were found in 22.5% (n = 41), 6% (n = 11) developed major complications defined as Clavien Dindo III-V and 16.5% (n = 30) had minor complications (Clavien Dindo I-II). The median Δ albumin was 22.75% (range: -18.46-47.14%). Delta albumin was found to be significantly higher in patients who developed complications after surgery (p = 0.03). Notably, neither preoperative (p = 0.28) nor postoperative albumin levels (p = 0.41) taken as absolute numerical values correlated with an eventful course following intestinal resection. In the multivariate analysis, based on a cut-off of 24.27%, Δ albumin remained an independent factor for surgical complications (p = 0.04, OR 2.232) next to conversion rate (p<0.001, OR 5.577) and the presence of an inflammatory mass (p = 0.003, OR 0.280). CONCLUSION: Δ albumin is a better prognostic marker for an eventful postoperative course after laparoscopic surgery in patients with Crohn's disease in comparison to albumin alone.

The role of visceral fat measured by computer tomography is yet not well defined in patients with Crohn's disease. Therefore, the present study was designed to assess the impact of visceral fat area on postoperative short-term outcome and surgical characteristics. We analyzed 95 patients, who underwent intestinal resection for symptomatic Crohn's disease at an academic tertiary referral center between 2003 and 2008. Visceral fat area was measured on preoperative computed tomography scans. Postoperative morbidity was graded according to the Clavien-Dindo classification. Visceral fat area was correlated with baseline characteristics, disease phenotype and 30-day morbidity. Body mass index and age were significantly associated with a higher visceral fat area (p = 0.001). Overall 19 (20.0%) postoperative complications were observed, of whom 7 (7.4%) patients required surgical re-intervention. No significant difference was found with regard to visceral fat area between patients with an uneventful and eventful postoperative course (no complications: median visceral fat area 52.0 cm2 SD 59.7, complications: 41.3 cm2 SD 42.8; p = 0.465). In contrast to current literature, we cannot support the role of visceral fat area for predicting postoperative course in Crohn's disease. In addition, no correlation of the visceral fat area and disease behavior was detected.

BACKGROUND: The Neutrophil-to-lymphocyte-ratio has recently gained increased attention as a prognostic marker for malignant disease and short term outcomes. There is little data available in patients with Crohn's disease, thus the present study was conducted to correlate preoperative Neutrophil-to-lymphocyte-ratio values with disease phenotype and postoperative course. METHODS: We comprised 373 patients, who underwent intestinal resection for symptomatic Crohn's disease at an academic tertiary referral centre between 2000 and 2014. Preoperative Neutrophil-to-lymphocyte-ratio values were calculated and analyzed in regard to disease phenotype and 30-day morbidity rate. All relevant data were obtained from the institutional database and individual chart review. RESULTS: Male patients had significantly higher preoperative Neutrophil-to-lymphocyte-ratio values compared to female patients (5 vs. 4; p = 0.0075). A higher Neutrophil-to-lymphocyte-ratio was also found in patients with an acute indication for surgery (6.15 vs. 4.3; p = 0.0374), presenting with abscesses (5.36 vs. 4.28; p = 0.0254), inflammatory masses (5.23 vs. 4.08; p = 0.0294) or malignancy in the resected specimen (9.06 vs. 4.35, p = 0.0231). Surprisingly, patients developing postsurgical complications showed significantly lower Neutrophil-to-lymphocyte-ratio values (3.77 vs. 4.67; p = 0.0461). CONCLUSIONS: Elevated preoperative Neutrophil-to-lymphocyte-ratio in symptomatic Crohn's disease is not predictive for complications. However, Neutrophil-to-lymphocyte-ratio showed a significant correlation with specific disease phenotypes. Most strikingly, Neutrophil-to-lymphocyte-ratio was highly elevated in patients with a colorectal cancer in the resected specimen, which needs to be addressed in future studies.

BACKGROUND: The modified Glasgow prognostic score (mGPS) has recently gained increased attention as a prognostic marker for malignant disease survival and postoperative short-term complications. Due to lacking data, the present study was conducted to correlate the mGPS with the postoperative course in patients following surgery for Crohn's disease. METHODS: We enrolled 341 patients who underwent intestinal resection for symptomatic Crohn's disease at a tertiary referral centre between 2000 and 2014. All relevant data were obtained from the institutional database and individual chart review. Thirty-day morbidity was defined according to the Clavien-Dindo classification. RESULTS: A total of 79 (23.17%) postoperative complications were identified (grade I and II: nâ¯= 54, 15.84%; grade III and IV: nâ¯= 23, 6.74%; grade V: nâ¯= 2, 0.59%). The mGPS did not show any correlation with an eventful postoperative course following surgery (no complication: median mGPS: 1, range 0-2; complications: median mGPS: 1, range 0-2; pâ¯= 0.8521). In addition, the occurrence of an anastomotic leakage was not associated with a higher mGPS (pâ¯= 0.8592). Patients with an acute indication for surgery (nâ¯= 29, 11.44%) had higher median mGPS (median: 2, range 0-2) in contrast to patients who were operated on electively (median: 1, range 0-2; pâ¯= 0.0003). No other correlation between surgical characteristics and mGPS was detected. CONCLUSIONS: In the present study, we could clearly demonstrate that an acute indication for surgery in symptomatic Crohn's disease is associated with higher mGPS scores. However, the mGPS did not correlate with postoperative complications. Further studies are required to define the prognostic value of mGPS in Crohn's disease patients.
RESUMO
AIM: To evaluate frequency and clinical course of incidental adenocarcinoma in patients with stricturing Crohn's disease (CD). METHODS: In this study, consecutive patients, who were operated on for stricturing CD between 1997-2012, were included at an academic tertiary referral center. Demographic data and clinical course were obtained by an institutional database and individual chart review. Besides baseline characteristics, intraoperative findings and CD related history were also recorded. Colorectal cancer was classified and staged according to the Union for International Cancer Control (UICC). RESULTS: During the study period 484 patients underwent resections due to stricturing CD. Incidental adenocarcinoma was histologically confirmed in 6 (1.2%) patients (4 males, 2 females). Patients diagnosed with colorectal cancer had a median age of 43 (27-66) years and a median history of CD of 16 (7-36) years. Malignant lesions were found in the rectum (n = 4, 66.7%), descending colon (n = 1, 16.7%) and ileocolon (n = 1, 16.7%). According to the UICC classification two patients were stages as I (33.3%), whereas the other patients were classified as stage IIA (16.7%), stage IIIB (16.7%), stage IIIC (16.7%) and stage IV (16.7%), respectively. After a median follow-up of 2 (0.03-8) years only 1 patient is still alive. CONCLUSION: The frequency of incidental colorectal cancer in patients, who undergo surgery for stenotic CD, is low but associated with poor prognosis. However, surgeons need to be aware about the possibility of malignancy in stricturing CD, especially if localized in the rectum.

PURPOSE: Due to a lack of data, the present study was designed to assess the impact of advanced age on surgical characteristics and short-term outcome of patients operated on for symptomatic Crohn's disease. METHODS: We enrolled 454 consecutive Crohn's disease patients, who underwent intestinal resection at an academic tertiary referral center between 1997 and 2012. Patients were divided into 3 groups according to their age (group I: <30 years, group II: 30-50 years, group III: >50 years) and analyzed retrospectively. RESULTS: Altogether, 152 (33.5%) patients were included in group I, 234 (51.5%) in group II and 68 (15.0%) in group III. Abscess formation and penetrating disease were significantly more common in younger patients (p = 0.0014 and p = 0.0182). The number of intestinal resections was higher in older patients (p < 0.0001), whereas the laparoscopic approach was more frequently observed in younger adults (p = 0.0006). Group II (n = 58 (24.8%)) and group III (n = 15 (22.1%)) showed significantly more complications compared to group I (n = 20 (13.2%)) (p = 0.0346). Notably, major complications and anastomotic leaks were significantly higher in older patients (p = 0.0004). CONCLUSION: Crohn's disease patients of advanced age show different surgical characteristics compared to younger patients and are at an increased risk of developing postoperative complications.

BACKGROUND: Laparoscopic surgery for penetrating Crohn's disease (CD) still remains highly conflicting due to a lack of sufficient data. Therefore, the following large study was designed to compare postoperative outcomes after minimal-invasive resections for penetrating and non-penetrating CD. METHODS: Consecutive patients, who underwent laparoscopic intestinal resection for symptomatic CD at a tertiary academic referral center, were included. Patients were divided according to perioperative findings in penetrating and non-penetrating type of disease. All clinical data were obtained from an institutional database and analyzed retrospectively. RESULTS: Of 234 patients enrolled, 101 patients [females: n = 54 (53.5 %)] were operated on for non-penetrating CD and 133 patients [females: n = 50 (37.6 %)] for penetrating CD. Fistulas (p < 0.001), inflammatory mass (p < 0.001) and abscess formation (p < 0.001) were observed more frequently in the perforating group. Ileocolic resections were performed predominantly in both groups [perforating CD: n = 110 (82.7 %), non-perforating CD: n = 82 (81.2 %)], with more complex resections (>1 intestinal resection) found in perforating CD (p < 0.001). Conversion rates did not differ significantly. Notably, 30-day postoperative morbidity was comparable for both groups [perforating CD: n = 20 (15 %), non-perforating CD: n = 19 (18.8 %), p = 0.44]. Postoperative complication rates graded according to the Clavien-Dindo classification showed no difference too (p = 0.49). CONCLUSION: Laparoscopic surgery can be conducted safely in selected patients with penetrating CD without increasing the risk of postoperative complications. This finding needs to be implemented in future guidelines.
