Multimodal Prehabilitation in Patients Undergoing Complex Colorectal Surgery, Liver Resection, and Hyperthermic Intraperitoneal Chemotherapy (HIPEC): A Pilot Study on Feasibility and Potential Efficacy.

BACKGROUND: Surgery for complex primary and metastatic colorectal cancer (CRC), such as liver resection and hyperthermic intraperitoneal chemotherapy (HIPEC), in academic settings has led to improved survival but is associated with complications up to 75%. Prehabilitation has been shown to prevent complications in non-academic hospitals. This pilot study aimed to determine the feasibility and potential efficacy of a multimodal prehabilitation program in patients undergoing surgery in an academic hospital for complex primary and metastatic CRC. METHODS: All patients awaiting complex colorectal surgery, liver resection, or HIPEC from July 2019 until January 2020 were considered potentially eligible. Feasibility was measured by accrual rate, completion rate, adherence to the program, satisfaction, and safety. To determine potential efficacy, postoperative outcomes were compared with a historical control group. RESULTS: Sixteen out of twenty-five eligible patients (64%) commenced prehabilitation, and fourteen patients fully completed the intervention (88%). The adherence rate was 69%, as 11 patients completed >80% of prescribed supervised trainings. No adverse events occurred, and all patients expressed satisfaction with the program. The complication rate was significantly lower in the prehabilitation group (37.5%) than the control group (70.2%, p = 0.020). There was no difference in the type of complications. CONCLUSION: This pilot study illustrates that multimodal prehabilitation is feasible in the majority of patients undergoing complex colorectal cancer, liver resection, and HIPEC in an academic setting.

Laparoscopic Probe for Sentinel Lymph Node Harvesting Using Magnetic Nanoparticles.

OBJECTIVE: Sentinel lymph node harvesting is an essential step in the surgical treatment of a growing number of malignancies. Various techniques are available to facilitate this purpose. The present study reports a new laparoscopic technique for lymph node harvesting using magnetic nanoparticles containing a superparamagnetic iron-oxide core and dextran coating. This study assesses the clinical relevance of the prototype and provides input for further technological development on the way to clinical implementation. METHODS: A laparoscopic differential magnetometer prototype was built, utilizing a nonlinear detection principle (differential magnetometry) for magnetic identification of lymph nodes. The iron content sensitivity, depth & spatial sensitivity, and angular sensitivity were analyzed to investigate clinical options. RESULTS: The minimum detectable amount of iron was 9.8 µg at a distance of 1 mm. The detection depth was 5, 8, and 10 mm for samples containing 126, 252, and 504 µg iron, respectively. The maximum lateral detection distance was 5, 7, and 8 mm for samples containing 126, 252, and 504 µg iron, respectively. A sample containing 504 µg iron was detectable at all angulations assessed (0°, 30°, 60° and 90°). CONCLUSION: The laparoscopic differential magnetometer demonstrates promising results for further investigation and development towards laparoscopic lymph node harvesting using magnetic nanoparticles. SIGNIFICANCE: The laparoscopic differential magnetometer facilitates a novel method for sentinel lymph node harvesting, which helps to determine prognosis and treatment of cancer patients.

Laparoscopic Intestinal Vaginoplasty in Transgender Women: An Update on Surgical Indications, Operative Technique, Perioperative Care, and Short- and Long-Term Postoperative Issues.

"Surgical (re)construction of a vagina (vaginoplasty) is performed in biological women with congenital or postablative vaginal absence and in transgender women. Penile inversion vaginoplasty is the gold surgical standard for genital Gender Affirmation Surgery in transgender women. In absence of sufficient penoscrotal skin, due to penoscrotal hypoplasia, circumcision, penile trauma with loss of penile skin quantity and/or quality, or when primary vaginoplasty has failed, intestinal vaginoplasty can be performed. This article provides an update on surgical indications of intestinal vaginoplasty, operative technique, perioperative care, and short- and long-term postoperative issues. A review of recent literature is performed."

The effect of surgical fecal stream diversion of the healthy colon on the colonic microbiota.

OBJECTIVES: The intestinal microbiota plays an important role in intestinal health. After colonic diversion from the fecal stream, luminal nutrients for bacteria are expected to be depleted, inducing changes in microbial composition. In this study, we describe microbial changes in the healthy colon following surgical fecal stream diversion, studied in the surgically constructed sigmoid-derived neovagina. METHODS: At various postoperative times after sigmoid vaginoplasty, rectal, neovaginal, and skin microbial swabs were obtained for microbial analysis by interspacer profiling, a PCR-based bacterial profiling technique. Differences in bacterial profiles, in terms of bacterial abundance and phylum diversity, were assessed. Microbial dissimilarities between anatomical locations were analyzed with principal coordinate analysis and partial least squares discriminant analysis. RESULTS: Bacterial samples were obtained from 28 patients who underwent sigmoid vaginoplasty. By principal coordinate analysis, microbial profiles of samples from the sigmoid-derived neovagina were distinctively different from rectal samples. Partial least squares discriminant analysis showed that the most discriminative species derived from the phylum Bacteroidetes. The abundance and diversity of Bacteroidetes species were reduced following fecal stream diversion compared with rectal samples (median Shannon diversity index of 2.76 vs. 2.18, P<0.01). Similar abundance of Phyla Firmicutes, Actinobacteria, Fusobacteria, Verrucomicrobia, and Proteobacteria was observed. CONCLUSION: By analyzing the microbiome of sigmoid-derived neovaginas, we studied the effects of fecal diversion on the microbial composition of the healthy intestine. Most changes were observed in the phylum Bacteroidetes, indicating that these bacteria are likely part of the diet-dependent (butyrate-producing) colonic microbiome. Bacteria of other phyla are likely to be part of the diet-independent microbiome.

Personalised perioperative care by e-health after intermediate-grade abdominal surgery: a multicentre, single-blind, randomised, placebo-controlled trial.

BACKGROUND: Instructing and guiding patients after surgery is essential for successful recovery. However, the time that health-care professionals can spend with their patients postoperatively has been reduced because of efficiency-driven, shortened hospital stays. We evaluated the effect of a personalised e-health-care programme on return to normal activities after surgery. METHODS: A multicentre, single-blind, randomised controlled trial was done at seven teaching hospitals in the Netherlands. Patients aged 18-75 years who were scheduled for laparoscopic cholecystectomy, inguinal hernia surgery, or laparoscopic adnexal surgery for a benign indication were recruited. An independent researcher randomly allocated participants to either the intervention or control group using computer-based randomisation lists, with stratification by sex, type of surgery, and hospital. Participants in the intervention group had access to a perioperative, personalised, e-health-care programme, which managed recovery expectations and provided postoperative guidance tailored to the patient. The control group received usual care and access to a placebo website containing standard general recovery advice. Participants were unaware of the study hypothesis and were asked to complete questionnaires at five timepoints during the 6-month period after surgery. The primary outcome was time between surgery and return to normal activities, measured using personalised patient-reported outcome measures. Intention-to-treat and per-protocol analyses were done. This trial is registered in the Netherlands National Trial Register, number NTR4699. FINDINGS: Between Aug 24, 2015, and Aug 12, 2016, 344 participants were enrolled and randomly allocated to either the intervention (n=173) or control (n=171) group. 14 participants (4%) were lost to follow-up, with 330 participants included in the primary outcome analysis. Median time until return to normal activities was 21 days (95% CI 17-25) in the intervention group and 26 days (20-32) in the control group (hazard ratio 1·38, 95% CI 1·09-1·73; p=0·007). Complications did not differ between groups. INTERPRETATION: A personalised e-health intervention after abdominal surgery speeds up the return to normal activities compared with usual care. Implementation of this e-health programme is recommended in patients undergoing intermediate-grade abdominal, gynaecological, or general surgical procedures. FUNDING: ZonMw.

Ileal vaginoplasty as vaginal reconstruction in transgender women and patients with disorders of sex development: an international, multicentre, retrospective study on surgical characteristics and outcomes.

OBJECTIVE: To describe the surgical outcomes of ileal vaginoplasty in transgender women and patients with disorders of sex development (DSD). PATIENTS AND METHODS: Transgender women and patients with DSD, who underwent ileal vaginoplasty at the VU University Medical Center Amsterdam, University Hospital Trieste, University Hospital Essen, and Belgrade University Hospital, were retrospectively identified. A chart review was performed, recording surgical technique, intraoperative characteristics, complications, and re-operations. RESULTS: We identified a total of 32 patients (27 transgender and five non-transgender), with a median (range) age of 35 (6-63) years. Ileal vaginoplasty was performed as the primary procedure in three and as a revision procedure in the remaining 29. The mean (sd) operative time was 288 (103) min. The procedure was performed laparoscopically (seven patients) or open (25). An ileal 'U-pouch' was created in five patients and a single lumen in 27. Intraoperative complications occurred in two patients (one iatrogenic bladder damage and one intraoperative blood loss necessitating transfusion). The median (range) hospitalisation was 12 (6-30) days. Successful neovaginal reconstruction was achieved in all. The mean (sd) achieved neovaginal depth was 13.2 (3.1) cm. The median (range) clinical follow-up was 35 (3-159) months. In one patient a recto-neovaginal fistula occurred, which lead to temporary ileostomy. Introital stenosis occurred in four patients (12.5%). CONCLUSION: Ileal vaginoplasty can be performed with few intra- and postoperative complications. It appears to have similar complication rates when compared to sigmoid vaginoplasty. It now seems to be used predominantly for revision procedures.

Fluorescent Imaging With Indocyanine Green During Laparoscopic Cholecystectomy in Patients at Increased Risk of Bile Duct Injury.

BACKGROUND: Although rare, injury to the common bile duct (CBD) during laparoscopic cholecystectomy (LC) can be reduced by better intraoperative visualization of the cystic duct (CD) and CBD. The aim of this study was to establish the efficacy of early visualization of the CD and the added value of CBD identification, using near-infrared (NIR) light and the fluorescent agent indocyanine green (ICG), in patients at increased risk of bile duct injury. MATERIALS AND METHODS: Patients diagnosed with complicated cholecystitis and scheduled for LC were included. The CBD and CD were visualized with NIR light before and during dissection of the liver hilus and at critical view of safety (CVS). RESULTS: Of the 20 patients originally included, 2 were later excluded due to conversion. In 6 of 18 patients, the CD was visualized early during dissection and prior to imaging with conventional white light. The CBD was additionally visualized with ICG-NIR in 7 of 18 patients. In 1 patient, conversion was prevented due to detection of the CD and CBD with ICG-NIR. CONCLUSIONS: Early visualization of the CD or additional identification of the CBD using ICG-NIR in patients with complicated cholecystolithiasis can be helpful in preventing CBD injury. Future studies should attempt to establish the optimal dosage and time frame for ICG administration and bile duct visualization with respect to different gallbladder pathologies.

Lethal Necrotizing Cellulitis Caused by ESBL-Producing E. Coli after Laparoscopic Intestinal Vaginoplasty.

BACKGROUND: The absence of a functional vagina has a negative effect on the quality of life of women. Multiple surgical procedures have been described for vaginal reconstruction in these patients. CASE: We present a case of an 18-year-old transgender woman, who underwent laparoscopic intestinal vaginoplasty as vaginal reconstruction, and subsequently developed septic shock and multiple organ failure on the basis of an extended-spectrum ß-lactamase-producing Escherichia coli. A severe progression of the necrotizing fasciitis was lethal, despite repeated surgical debridement, intravenous antibiotic use, and supportive care at the intensive care unit. SUMMARY AND CONCLUSION: Although vaginal reconstruction has a positive influence on the quality of life in transgender women, physicians and patients need to be aware of serious complications that might arise.

Total laparoscopic sigmoid vaginoplasty.

OBJECTIVE: To demonstrate step by step our technique for total laparoscopic sigmoid vaginoplasty. DESIGN: Surgical video tutorial. SETTING: Academic medical center. PATIENT(S): Transgender women with penile hypoplasia or with a failed primary vaginoplasty and biological women with either acquired or congenital absence of a functional vagina. INTERVENTION(S): An original technique for total laparoscopic sigmoid vaginoplasty is shown on video. Surgery is performed via a simultaneous abdomino-perineal approach. The genital surgeon dissects the neovaginal cavity and performs a bilateral orchiectomy and shortening of the urethra. Out of penile and scrotal skin, a clitoro-vulvaplasty is created. Meanwhile, the laparoscopic surgeon mobilizes the sigmoid segment and transects it down to the base of the sigmoid arteries. The segment is guided in an iso-peristaltic way through the neovaginal tunnel on to the perineum. The distal staple line is opened and sutured in an exaggerated interdigitating fashion to the perineum and inverted penile skin. Length of the segment is measured with a transilluminated perspex dildo, after which the segment is stapled at the proper level. A neovaginopexy is performed on the promontory. Bowel continuity is restored with an intra-abdominal side-to-side oversewn stapled anastomosis. The patient provided written informed consent for the use of this video in this article. MAIN OUTCOME MEASURE(S): None. RESULT(S): Given current literature, intestinal vaginoplasty is associated with low complication rates. Since 2008 our group performed 42 primary and 21 secondary procedures, mainly in transgender women, with at least 1 year of clinical follow-up. Complications comprised three rectal perforations and two anastomotic leakages. These were addressed laparoscopically without long-term fistula formation. There were no conversions to laparotomy. CONCLUSION(S): Total laparoscopic sigmoid vaginoplasty is a feasible and safe procedure in the hands of an experienced team with the right infrastructure. It provides good surgical and functional results. In selected cases it is indicated for primary vaginoplasty, as well as for revision vaginoplasty.

Primary Total Laparoscopic Sigmoid Vaginoplasty in Transgender Women with Penoscrotal Hypoplasia: A Prospective Cohort Study of Surgical Outcomes and Follow-Up of 42 Patients.

BACKGROUND: In young transgender women previously treated with puberty-suppressing hormones, penoscrotal hypoplasia can make penoscrotal inversion vaginoplasty unfeasible. The aim of this study was to prospectively assess surgical outcomes and follow-up of total laparoscopic sigmoid vaginoplasty as primary reconstruction in a cohort of transgender women with penoscrotal hypoplasia. METHODS: Baseline demographics, surgical characteristics, and intraoperative and postoperative complications of all performed total laparoscopic sigmoid vaginoplasty procedures were prospectively recorded. RESULTS: From November of 2007 to July of 2015, 42 transgender women underwent total laparoscopic sigmoid vaginoplasty as primary vaginal reconstruction. The mean age at the time of surgery was 21.1 ± 4.7 years. Mean follow-up time was 3.2 ± 2.1 years. The mean operative duration was 210 ± 44 minutes. There were no conversions to laparotomy. One rectal perforation was recognized during surgery and immediately oversewn without long-term consequences. The mean length of hospitalization was 5.7 ± 1.1 days. One patient died as a result of an extended-spectrum beta-lactamase-positive necrotizing fasciitis leading to septic shock, with multiorgan failure. Direct postoperative complications that needed laparoscopic reoperation occurred in three cases (7.1 percent). In seven cases (17.1 percent), long-term complications needed a secondary correction. After 1 year, all patients had a functional neovagina with a mean depth of 16.3 ± 1.5 cm. CONCLUSIONS: Total laparoscopic sigmoid vaginoplasty seems to have a similar complication rate as other types of elective laparoscopic colorectal surgery. Primary total laparoscopic sigmoid vaginoplasty is a feasible gender-confirming surgical technique with good functional outcomes for transgender women with penoscrotal hypoplasia. CLINICAL QUESTIO/LEVEL OF EVIDENCE: Therapeutic, IV.

Patient-Reported Esthetic and Functional Outcomes of Primary Total Laparoscopic Intestinal Vaginoplasty in Transgender Women With Penoscrotal Hypoplasia.

INTRODUCTION: Puberty-suppressing hormonal treatment may result in penoscrotal hypoplasia in transgender women, making standard penile inversion vaginoplasty not feasible. For these patients, intestinal vaginoplasty is a surgical alternative, but knowledge on patient-reported postoperative outcomes and quality of life is lacking. AIMS: To assess patient-reported functional and esthetic outcomes, quality of life, satisfaction, and sexual well-being after primary total laparoscopic intestinal vaginoplasty in transgender women. METHODS: A survey study was performed on transgender women who underwent primary total laparoscopic intestinal vaginoplasty with at least 1 year of clinical follow-up. Thirty-one transgender women completed the questionnaires (median age at time of surgery = 19.1 years, range = 18.3-45.0) after a median clinical follow-up of 2.2 years (range = 0.8-7.5). Consenting women were asked to complete a combined questionnaire of the Subjective Happiness Scale, the Satisfaction With Life Scale, Cantril's Ladder of Life Scale, the Female Sexual Function Index, the Female Genital Self-Imaging Scale, the Amsterdam Hyperactive Pelvic Floor Scale-Women, and a questionnaire addressing postoperative satisfaction. MAIN OUTCOME MEASURES: Patient-reported functional and esthetic outcomes and postoperative quality of life. RESULTS: Patients graded their life satisfaction a median of 8.0 (range = 4.0-10.0) on Cantril's Ladder of Life Scale. Patients scored a mean total score of 27.7 ± 5.8 on the Satisfaction With Life Scale, which indicated high satisfaction with life, and a mean total score of 5.6 ± 1.4 on the Subjective Happiness Scale. Functionality was graded a median score of 8.0 of 10 (range = 1.0-10.0) and esthetics a score of 8.0 out of 10 (range = 3.0-10.0). The mean Female Sexual Function Index total score of sexually active transgender women was 26.0 ± 6.8. CONCLUSION: This group of relatively young transgender women reported satisfactory functional and esthetic results of the neovagina and a good quality of life, despite low Female Sexual Function Index scores.

Clinical Characteristics and Management of Neovaginal Fistulas After Vaginoplasty in Transgender Women.

OBJECTIVE: To describe our experience and results obtained in the management of neovaginal fistulas after vaginoplasty as gender reassignment surgery in transgender women. METHODS: A retrospective study was performed of 1,082 transgender women who underwent 1,037 primary and 80 revision vaginoplasty procedures between 1990 and 2015. Thirty-five women underwent both primary and later revision vaginoplasty at our institution. Patient, clinical, surgical, and outcome characteristics were reviewed. RESULTS: We treated 25 (2.3%) patients for 13 rectoneovaginal, 11 urethroneovaginal, and one pouch-neovaginal fistulas. Patients undergoing revision vaginoplasty were at higher risk of rectoneovaginal fistula development (0.8% compared with 6.3%, P<.01, odds ratio 8.6, 95% confidence interval 2.7-26.9). Of 23 intraoperatively identified and oversewn rectal perforations, four (17.4%) patients developed a rectoneovaginal fistula. In four patients, fecal diversion was achieved through temporary colostomy or ileostomy with direct (n=1) or delayed (n=3) fistula closure. In six patients, urethroneovaginal fistula arose after a complication such as meatal stenosis. Two patients underwent temporary suprapubic cystostomy for urinary diversion. In most patients, fistulectomy and primary closure or a local advancement flap was sufficient to treat the fistula. CONCLUSION: Neovaginal fistulas are uncommon after vaginoplasty. Symptoms of neovaginal fistulas are comparable with those of vaginal fistulas. In most patients, the diagnosis can be made based on symptoms and physical examination alone. It seems that a complicated course (eg, intraoperative rectal perforation or meatal stenosis) predisposes for fistula formation. Surgical repair of neovaginal fistulas is associated with few intraoperative and postoperative complications and does not seem to impair neovaginal function.

A modified Delphi method toward multidisciplinary consensus on functional convalescence recommendations after abdominal surgery.

BACKGROUND: Evidence-based information on the resumption of daily activities following uncomplicated abdominal surgery is scarce and not yet standardized in medical guidelines. As a consequence, convalescence recommendations are generally not provided after surgery, leading to patients' insecurity, needlessly delayed recovery and prolonged sick leave. The aim of this study was to generate consensus-based multidisciplinary convalescence recommendations, including advice on return to work, applicable for both patients and physicians. METHOD: Using a modified Delphi method among a multidisciplinary panel of 13 experts consisting of surgeons, occupational physicians and general practitioners, detailed recommendations were developed for graded resumption of 34 activities after uncomplicated laparoscopic cholecystectomy, laparoscopic and open appendectomy, laparoscopic and open colectomy and laparoscopic and open inguinal hernia repair. A sample of occupational physicians, general practitioners and surgeons assessed the recommendations on feasibility in daily practice. The response of this group of care providers was discussed with the experts in the final Delphi questionnaire round. RESULTS: Out of initially 56 activities, the expert panel selected 34 relevant activities for which convalescence recommendations were developed. After four Delphi rounds, consensus was reached for all of the 34 activities for all the surgical procedures. A sample of occupational physicians, general practitioners and surgeons regarded the recommendations as feasible in daily practice. CONCLUSION: Multidisciplinary convalescence recommendations regarding uncomplicated laparoscopic cholecystectomy, appendectomy (laparoscopic, open), colectomy (laparoscopic, open) and inguinal hernia repair (laparoscopic, open) were developed by a modified Delphi procedure. Further research is required to evaluate whether these recommendations are realistic and effective in daily practice.

Long-Term Follow-Up of Transgender Women After Secondary Intestinal Vaginoplasty.

INTRODUCTION: Intestinal vaginoplasty with a sigmoid colon or ileal segment is an established surgical technique for vaginal reconstruction. Little has been reported on long-term (functional) outcome and postoperative quality of life. AIMS: To assess the surgical and long-term psychological outcomes of secondary intestinal vaginoplasty performed from 1970 through 2000 in transgender women. METHODS: Transgender women who underwent intestinal vaginoplasty from 1970 through 2000 were identified from our hospital registry. Demographics, surgical characteristics, complications, and reoperations were recorded. Traceable women were invited to fill out a set of questionnaires (quality-of-life questionnaire, Female Sexual Function Index, Amsterdam Hyperactive Pelvic Floor Scale for Women, Female Genital Self-Imaging Scale, and self-evaluation of vaginoplasty questionnaire) and attend the outpatient clinic for physical, endoscopic, and histologic examination of the neovagina. MAIN OUTCOME MEASURES: Primary outcomes were complications, reoperations, self-perceived quality of life, and functional and esthetic self-evaluation. RESULTS: Twenty-four transgender women were identified who underwent intestinal vaginoplasty as a secondary procedure from 1970 through 2000. There were no intraoperative complications. Three intestinal neovaginas were surgically removed because of postoperative complications. Nineteen women (79%) underwent at least one genital reoperation, most commonly introitus plasty (n = 13, 54%). Five women were deceased at time of analysis. Nine women consented to partake in the study (median age = 58 years, range = 50-73; median postoperative time = 29.6 years, range = 17.2-34.3). They were generally satisfied with life and scored 5.9 of 7 on a subjective happiness scale. Neovaginal functionality was rated as 7.3 and appearance as 7.4 of 10. CONCLUSION: In our institution, intestinal vaginoplasty before 2000 was always performed as a revision procedure after a previous vaginoplasty had failed. Although surgical corrections were frequently necessary, women reported satisfaction with the surgical outcome and with life in general.

Diversion neovaginitis after sigmoid vaginoplasty: endoscopic and clinical characteristics.

OBJECTIVE: To assess the endoscopic characteristics of the sigmoid-derived neovagina, which have been scarcely described. DESIGN: Prospective observational study. SETTING: University tertiary medical center. PATIENT(S): Patients that underwent sigmoid vaginoplasty. INTERVENTION(S): Patients were invited yearly to undergo neovaginoscopy and sigmoidoscopy, preceded by taking a medical history and physical examination, as routine follow-up. MAIN OUTCOME MEASURE(S): Endoscopic signs of neovaginal inflammation. RESULT(S): Thirty-four patients with a sigmoid neovagina underwent a total of 43 combined neovaginoscopies and sigmoidoscopies. After a mean postoperative time of 23 months, the most notable endoscopic features of the sigmoid-derived neovagina comprised a diminished vascular pattern, edema, granularity, friability, decreased resilience, and erythema. In the control rectosigmoidoscopy images, no concurrent abnormalities were observed. When applying the MAYO score to the neovaginal images, 12 (35%) patients scored MAYO 0, 19 (56%) MAYO I, 3 (9%) MAYO II, and none MAYO III. The presence of neovaginal discharge and malodor correlated with inflammatory endoscopic alterations. CONCLUSION(S): The endoscopic appearance of a sigmoid segment after use in neovaginoplasty differs significantly from that of the remaining rectosigmoid. Inflammatory changes of the sigmoid-derived neovagina were observed in most patients. Clinically, the inflammatory changes appear similar to those encountered in diversion colitis.

Morphological spectrum of neovaginitis in autologous sigmoid transplant patients.

AIMS: Autologous intestinal grafts are used to (re)create a vagina in selected patients. The risk of diversion colitis is mentioned as a disadvantage, although its prevalence remains unclear. This study aimed to assess the histopathological characteristics of the sigmoid-derived neovaginal epithelial lining after diverting surgery and correlate these with clinical findings. METHODS AND RESULTS: Biopsy specimens were obtained from the epithelial lining of the sigmoid-derived neovagina and remaining rectosigmoid as regular follow-up from 26 patients with a median age of 22 years (range 19-52) and median postoperative follow-up of 13 months (range 6-52). Medical history, neovaginal symptoms and sexual activity were documented. An experienced gastrointestinal histopathologist assessed the specimens using a descriptive item-score, comprising signs of chronic and active inflammation. Inflammatory changes were observed in 21 (80.7%) neovaginal and one (3.8%) rectosigmoid specimens. The neovaginal appearance was characterized by an increase of lymphoid aggregates and lymphoplasmacellular infiltrate. Other common features were the presence of polymorphonuclear neutrophils and Paneth cell metaplasia. Neovaginal discharge was correlated with the presence of inflammatory changes (P = 0.008, Spearman's rho = 0.506). DISCUSSION: Acute and chronic inflammation of the sigmoid-derived neovagina was commonly observed and consistent with a proposed diagnosis of diversion neovaginitis. Neovaginal discharge correlates with this histopathological entity.

Surgery in (pre)malignant celiac disease.

AIM: To report the outcome of surgery in patients with (pre)malignant conditions of celiac disease (CD) and the impact on survival. METHODS: A total of 40 patients with (pre)malignant conditions of CD, ulcerative jejunitis (n = 5) and enteropathy associated T-cell lymphoma (EATL) (n = 35), who underwent surgery between 2002 and 2013 were retrospectively evaluated. Data on indications, operative procedure, post-operative morbidity and mortality, adjuvant therapy and overall survival (OS) were collected. Eleven patients with EATL who underwent chemotherapy without resection were included as a control group for survival analysis. Patients were followed-up every three months during the first year and at 6-mo intervals thereafter. RESULTS: Mean age at resection was 62 years. The majority of patients (63%) underwent elective laparotomy. Functional stenosis (n = 13) and perforation (n = 12) were the major indications for surgery. In 70% of patients radical resection was performed. Early postoperative complications, mainly due to leakage or sepsis, occurred in 14/40 (35%) of patients. Eight patients required reoperation. More patients who underwent resection in the acute setting (n = 3, 20%) died compared to patients treated in the elective setting. With a median follow-up of 20 mo, seven patients (18%) required reoperation due to long-term complications. Significantly more patients who underwent acute surgery could not be treated with adjuvant chemotherapy. Patients who first underwent surgical resection showed significantly better OS than patients who received chemotherapy without resection. CONCLUSION: Although the complication rate is high, the preferred first step of treatment in (pre)malignant CD consists of local resection as early as possible to improve survival.

Adjuvant hyperthermic intraperitoneal chemotherapy (HIPEC) in patients with colon cancer at high risk of peritoneal carcinomatosis; the COLOPEC randomized multicentre trial.

BACKGROUND: The peritoneum is the second most common site of recurrence in colorectal cancer. Early detection of peritoneal carcinomatosis (PC) by imaging is difficult. Patients eventually presenting with clinically apparent PC have a poor prognosis. Median survival is only about five months if untreated and the benefit of palliative systemic chemotherapy is limited. Only a quarter of patients are eligible for curative treatment, consisting of cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CR/HIPEC). However, the effectiveness depends highly on the extent of disease and the treatment is associated with a considerable complication rate. These clinical problems underline the need for effective adjuvant therapy in high-risk patients to minimize the risk of outgrowth of peritoneal micro metastases. Adjuvant hyperthermic intraperitoneal chemotherapy (HIPEC) seems to be suitable for this purpose. Without the need for cytoreductive surgery, adjuvant HIPEC can be performed with a low complication rate and short hospital stay. METHODS/DESIGN: The aim of this study is to determine the effectiveness of adjuvant HIPEC in preventing the development of PC in patients with colon cancer at high risk of peritoneal recurrence. This study will be performed in the nine Dutch HIPEC centres, starting in April 2015. Eligible for inclusion are patients who underwent curative resection for T4 or intra-abdominally perforated cM0 stage colon cancer. After resection of the primary tumour, 176 patients will be randomized to adjuvant HIPEC followed by routine adjuvant systemic chemotherapy in the experimental arm, or to systemic chemotherapy only in the control arm. Adjuvant HIPEC will be performed simultaneously or shortly after the primary resection. Oxaliplatin will be used as chemotherapeutic agent, for 30 min at 42-43 °C. Just before HIPEC, 5-fluorouracil and leucovorin will be administered intravenously. Primary endpoint is peritoneal disease-free survival at 18 months. Diagnostic laparoscopy will be performed routinely after 18 months postoperatively in both arms of the study in patients without evidence of disease based on routine follow-up using CT imaging and CEA. DISCUSSION: Adjuvant HIPEC is assumed to reduce the expected 25 % absolute risk of PC in patients with T4 or perforated colon cancer to a risk of 10 %. This reduction is likely to translate into a prolonged overall survival. TRIAL REGISTRATION NUMBER: NCT02231086 (Clinicaltrials.gov).

Comparing Near-Infrared Imaging with Indocyanine Green to Conventional Imaging During Laparoscopic Cholecystectomy: A Prospective Crossover Study.

BACKGROUND: The aim of this study was to test and validate a novel noninvasive method for intraoperative visualization of extrahepatic bile ducts during laparoscopic cholecystectomy. Injury to the common bile duct (CBD) is a rare but major complication of laparoscopic cholecystectomy. Most injuries occur when anatomy is unclear due to the presence of anatomic variations, acute inflammation, or adhesions. PATIENTS AND METHODS: Thirty patients were included, and each received an intravenous injection of 0.05 mg/kg of indocyanine green (ICG) (ICG-Pulsion(®); PULSION Medical Systems AG, Munich, Germany) prior to the start of surgery. Laparoscopic cholecystectomy was performed according to standard procedures. The CBD and cystic duct (CD) were visualized before and during dissection of the liver hilus using a conventional laparoscopic camera and a recently developed near-infrared (NIR) camera (Olympus, Tokyo, Japan). RESULTS: Using ICG-NIR, the CBD and CD could be visualized 11 minutes (P=.008) and 8.6 minutes (P=.001) earlier than with a conventional camera. Both early (20/30 patients) and late (26/30 patients) identification of the CBD with ICG-NIR was significantly more frequent compared with conventional images (2/30 and 10/30, respectively; P<.001). One postoperative bilioma required re-admission and endoscopic retrograde cholangiopancreatography with stent placement. CONCLUSIONS: Identification of the CBD and CD using a low dose of ICG and the NIR camera was both faster and more frequent compared with conventional laparoscopic images during elective laparoscopic cholecystectomy.
