Life-threatening postoperative pancreatic fistula (grade C) after pancreaticoduodenectomy: incidence, prognosis, and risk factors.

BACKGROUND Pancreatic fistula (PF) is one of the most common postoperative complications of pancreatoduodenectomy (PD). A recent International Study Group on Pancreatic Fistula (ISGPF) definition grades the severity of PF according to the clinical impact on the patients hospital course. Although PF is generally treated conservatively (grade A), some cases may require interventional procedures (grade B) or may be life-threatening and necessitate emergency reoperation (grade C). The aim of the present study was to evaluate the incidence of postoperative grade C PF after PD and to assess the prognosis and risk factors for this life-threatening condition. STUDY DESIGN Between January 2000 and December 2006, 680 consecutive patients underwent PD in 5 digestive surgery departments in the northwest region of France (Lille, Amiens, Rouen, and Caen). PF was defined as drain output of any measurable volume of fluid on or after postoperative day 3 with amylase content greater than 3 times the serum amylase activity (ISGPF guidelines). To identify possible risk factors for grade C PF, we reviewed the records of 111 (16.3%) patients with postoperative PF and compared grade C cases with grade A+B cases. RESULTS The median age was 59 years (range 22-87). The male-to-female ratio was 1.6:1. Fifty-six (50.4%) PDs were performed via pancreaticogastrostomy and 55 via pancreaticojejunostomy. Overall mortality was 2% (n = 14). Grade C PF was observed in 36 (32%) patients, of whom 17 (47%) had sepsis due to an abdominal collection, 16 (44%) had postoperative bleeding, 10 (27.7%) had bleeding associated with abdominal collection, and 3 (9%) had multi-organ failure due to other causes. Of these 36 patients, 35 (97%) underwent reoperation. The mortality rate in grade C PF patients was 38.8%. The major causes of death were sepsis (n = 6) and recurrent bleeding after reoperation (n = 5). Grade C PF increased the duration of postoperative hospitalization (46 vs 29 days, P < .001). Univariate analysis showed that peroperative soft pancreatic parenchyma, peroperative blood transfusion, and postoperative bleeding were significant risk factors for grade C PF, with P values of .011, .003, and .001, respectively. No risk factors for grade C PF were identified in a multivariate analysis. The sensibility, specificity, positive predictive value, and negative predictive value of the presence of the 3 risk factors for grade C PF were 13.89%, 100%, 100%, and 70.75%, respectively. CONCLUSION Sixteen percent of patients had PF after PD. Among them, 30% had grade C PF, with a mortality rate of about 40%. Achievement of a 100% predictive positive value for grade C PF after PD in individuals with 3 discriminant risk factors (peroperative soft pancreatic parenchyma, peroperative transfusion, and postoperative bleeding) is a first step towards the identification of high-risk patients who should be managed differently from other patients with PF during or after PD.

Delayed functional outcomes associated with surgical management of deep rectovaginal endometriosis with rectal involvement: giving patients an informed choice

BACKGROUND The aim of this study was to compare delayed functional digestive and urinary outcomes following two different surgical procedures used in the management of rectal endometriosis. METHODS Women who had undergone surgical management of rectal endometriosis with at least 1 year of post-operative follow-up were included in a retrospective study. Post-operative symptoms were evaluated using specific questionnaires which focused on pelvic pain and functional outcomes. RESULTS There were 41 women who underwent surgical treatment of symptomatic rectal endometriosis. Post-operative follow-up was completed over 26 +/- 13 months (range 12-53). Colorectal segmental resection was performed in 25 women (61%) and nodule excision in 16 (39%). An increase in the number of daily stools > or =3 was observed in 13 (52%) and 3 (19%) patients managed, respectively, by segmental resection and nodule excision (P = 0.02). Severe constipation (<1 stool/5 days) was recorded in three women having undergone segmental resection. The probabilities of being free of dysmenorrhea, dyspareunia and non-cyclic pain at 24 months in women managed by segmental resection and nodule excision were, respectively, 80% (95% CI: 55-92%), 65% (95% CI: 42-81%), 43% (95% CI: 23-62%) and 62% (95% CI: 34-81%), 81% (95% CI: 52-94), 69% (95% CI: 40-86%). When pain recurrences occurred, a significantly lower post-operative score for pain was observed in both groups. No significant difference in pain improvement was found between surgical procedures. CONCLUSION Colorectal segmental resection appears to be associated with several unpleasant functional symptoms when compared with nodule excision. Information about functional outcomes should be provided to patients managed for rectal endometriosis, and should be considered when deciding on the most appropriate treatment of this disease.

Direct proportional relationship between endometrioma size and ovarian parenchyma inadvertently removed during cystectomy, and its implication on the management of enlarged endometriomas

BACKGROUND The aim of this study was to estimate whether or not the size of an endometrioma is related to the thickness of the ovarian parenchyma inadvertently excised along with the cyst wall. METHODS We performed a retrospective study including 35 women who had undergone endometrioma cystectomy, using an ovarian tissue sparing procedure. In total 38 specimens were studied by three pathologists as three women presented bilateral localizations, and all cyst diameters measured at least 30 mm. For each endometrioma, serial sections were performed, and on each section four different sites were randomly chosen to measure the thickness of glandular epithelium and stroma, of subjacent fibrosis, depending on the cyst, and of the ovarian parenchyma removed with the cyst. The diameter of the ovary was measured preoperatively either by MRI or ultrasound, and the area of the internal wall was then calculated. The relationships between the mean thickness of ovarian parenchyma removed and the variables were estimated and a multiple regression model identified independent predictors for ovarian parenchyma thickness. RESULTS Adjacent ovarian tissue was found in 37 cases (97%). The mean thickness of ovarian tissue removed was 1173 +/- 711 microm and that of the cyst wall was 851 +/- 499 microm. The thickness of the ovarian parenchyma removed presented a direct proportional relationship with cyst diameter (P = 0.015), and consequently with cyst wall area (P = 0.032). This relationship with cyst diameter was independent after adjustment on other variables (P = 0.032). CONCLUSION Endometrioma cystectomy even though performed with an accurate surgical technique leads to significant ovarian tissue removal, the thickness of which increases proportionally with cyst diameter.

Liver resection for breast cancer metastasis: Does it improve survival?

PurposeTo assess the outcome and prognostic factors of liver surgery for breast cancer metastasis.MethodsWe retrospectively examined 16 patients who underwent partial liver resection for breast cancer liver metastasis (BCLM). All patients had been treated with chemotherapy or hormonotherapy, or both, before referral for surgery. We confirmed by preoperative radiological examinations that metastasis was confined to the liver. The survival curve was estimated using the Kaplan-Meier method. Univariate and multivariate analysis were conducted to evaluate the role of the known factors of breast cancer survival.ResultsThe median age of the patients was 54 years (range 38–68) and the median disease-free interval between the diagnoses of breast cancer and liver metastasis was 54 months (range 7–120). Nine major and 7 minor hepatectomies were performed. There was no postoperative death. The overall 1-, 3-, and 5-year survival rates were 94%, 61%, and 33%, respectively. The median survival rate was 42 months. Univariate analysis revealed that hormone receptor status, number of metastases, a major hepatectomy, and a younger age were associated with a poorer prognosis. The survival rate was not influenced by the disease-free interval, grade or stage of breast cancer, or intraoperative blood transfusions. The number of liver metastases was identified as a significant independent factor of survival according to the Cox proportional hazard model (P = 0.04).ConclusionsLiver resection, when done in combination with adjuvant therapy, can improve the prognosis of selected patients with BCLM.

Systematic review of endometriosis pain assessment: how to choose a scale?

BACKGROUND Numerous studies concerning endometriosis and pain have been reported. However, there is no consensus on the best method to evaluate pain in endometriosis and many scales have been used. Moreover, there are only a few descriptions of minimal clinically important differences after treatment (MCID) to evaluate variations in pain. In our study, we aim to identify pain scales used in endometriosis pain treatment, to address their strong and weak points and to define which would be the ideal scale to help clinicians and researchers to evaluate endometriosis-related pain. METHODS A search of the MEDLINE and EMBASE databases was carried out for publications in English, French or Portuguese from 1980 to December 2012, for the words: endometriosis, treatment, pain. Studies were selected if they studied an endometriosis treatment and a pain scale was specified. A quantitative and a qualitative analysis of each scale was performed to define strong and weak points of each scale (systematic registration number: CRD42013005336). RESULTS A total of 736 publications were identified. After excluding duplications and applying inclusion criteria 258 studies remained. We found that the visual analog scale (VAS) is the most frequently used scale. Both VAS and the numerical rating scale (NRS) show a good balance between strong and weak points in comparison with others such as the Biberoglu and Behrman scale. Concerning MCID, only VAS, NRS and Brief Pain Inventory scales have reported MCID and, among these, only VAS MCID has been studied in endometriosis patients (VAS MCID = 10 mm). Adding the Clinical Global Impression score (CGI) to the pain scale allows calculation of the MCID. CONCLUSIONS When using pain scales their strengths and weaknesses must be known and included in the analysis. VAS is the most frequently used pain scale and, together with NRS, seems the best adapted for endometriosis pain measurement. The use of VAS or NRS for each type of typical pain related to endometriosis (dysmenorrhea, deep dyspareunia and non-menstrual chronic pelvic pain), combined with the CGI and a quality-of-life scale will provide both clinicians and researchers with tools to evaluate treatment response.

Obstetric and neonatal outcomes in grand multiparity

OBJECTIVE: To compare the incidence of antenatal and intrapartum complications and neonatal outcomes among grand multiparas with age-matched multiparas. METHODS: Six hundred twenty-one grand multiparas (para more than 4) women were prospectively compared with 621 age-matched multiparous (para 2–4) controls. RESULTS: Grand multiparity was associated with low socioeconomic status and education (odds ratio [OR]6.4; 95% confidence interval [CI] 4.5, 9.0), poorer prenatal care (OR 3.1; 95% CI 1.5, 6.1), smoking (OR 2.2; 95% CI 1.5, 3.2), and alcohol consumption (OR 9.0; 95% CI 2.1, 39.3). Grand multiparas had a higher body mass index (OR 1.5; 95% CI 1.2, 1.9) and rate of insulin-dependent gestational diabetes (OR 1.7; 95% CI 1.02, 3.1). They had more previous intrauterine (OR 4.2; 95% CI 1.5, 11.3) and perinatal deaths (OR 3.2; 95% CI 2.0, 5.0). They had fewer intrapartum complications (arrests of cervical dilatation [OR 0.19; 95% CI 0.06, 0.66], instrumental deliveries [OR 0.31; 95% CI 0.16, 0.59], and fever during labor [OR 0.47; 95% CI 0.26, 0.86]). Conditional logistic regression models found that grand multiparity was the most closely correlated factor to a previous history of fetal death (OR 4.3; 95% CI 1.6, 11.6), but it was not an independent predictor of insulin-dependent gestational diabetes mellitus (OR 1.3; 95% CI 0.75, 2.2). CONCLUSION: Grand multiparas, when compared with same-age multiparous controls, appear to have fewer intrapartum complications. However, they present several prenatal risk factors that require special antenatal care. LEVEL OF EVIDENCE: II-3

Bowel dysfunction before and after surgery for endometriosis

The relationship between deep fibrotic endometriosis of the rectum and digestive symptoms as well as the impact of surgical treatment on digestive complaints appears increasingly complex. With the exception of cases in which the disease leads to rectal stenosis, it seems likely that certain digestive symptoms are a result of cyclic inflammatory phenomena leading to irritation of the digestive tract and not necessarily the result of actual involvement of the rectum by the disease itself because they frequently occur in women free of rectal nodules. Functional or inflammatory bowel diseases and rectal hypersensitivity may be associated with pelvic endometriosis and consequently joepardize the hypothetical causal relationship between the presence of a rectal nodule and digestive complaints. Women treated surgically for rectal endometriosis may continue to experience postoperative digestive complaints, such as constipation. Despite successful surgery free of intra- and postoperative complications and significant improvement in well-being and pelvic pain, several unpleasant digestive symptoms may be incompletely cured by the surgery. Furthermore, de novo postoperative digestive complaints may occur after rectal surgery. Retrospective data suggest that performing colorectal resection is related to less favorable digestive functional outcomes than the use of conservative procedures such as shaving or full-thickness disc excision. These hypotheses need to be confirmed by prospective randomized trials comparing rectal radical and conservative approaches. Bearing in mind the complex relationship between rectal nodules, digestive symptoms and rectal surgery, particular care must be taken in the preoperative assessment of digestive function and in choosing the most suitable surgical procedure.

Recurrences and fertility after endometrioma ablation in women with and without colorectal endometriosis: a prospective cohort study

STUDY QUESTION What are the recurrence and pregnancy rates in women managed for ovarian endometrioma by ablation using plasma energy with and without associated surgery for colorectal endometriosis? SUMMARY ANSWER Concomitant management of colorectal endometriosis does not impact either risk of recurrences or probability of pregnancy in women managed for endometrioma ablation using plasma energy. WHAT IS KNOWN ALREADY No consensus exists on how best to manage patients presenting with ovarian endometriomas and colorectal endometriosis, in terms of impact on fertility preservation and recurrence rates. STUDY DESIGN, SIZE, DURATION A prospective series of consecutive patients managed for ovarian endometriomas by ablation using plasma energy, over a period of 48 consecutive months. The study included patients with associated colorectal endometriosis (n = 52) and those who were free of colorectal localizations of the disease (n = 72). No women were lost to follow-up. PARTICIPANTS/MATERIALS, SETTING, METHODS The 124 women included in this study were managed for either unilateral or bilateral ovarian endometriomas using plasma energy at a university tertiary care center. Recurrences and pregnancy rate were compared in patients with and without colorectal endometriosis. The minimum length of follow-up was 1 year. Cyst recurrences were assessed using pelvic ultrasound and magnetic resonance imaging. Kaplan-Meier and actuarial life-table analysis were used to estimate the recurrence-free survival curve and the probability of pregnancy. The Cox model was used to assess independent predictive factors for recurrences. Pregnancy likelihood and independent predictors were estimated using a regression logistic model. MAIN RESULTS AND THE ROLE OF CHANCE Mean follow-up was 32 ± 18 months. Forty-eight patients (40.3%) were presumed infertile and attended an assisted reproductive techniques (ART) center. Eighteen patients presented with a recurrence (14.5%). Bilateral localization of endometriomas was the only factor independently related to an increased risk of recurrences [hazard ratio 3.3, 95% confidence interval (CI) 1.2-9.4]. Of the 83 women wishing to conceive (66.9%), 51 became pregnant (61.4%) and 33 of these pregnancies were spontaneous (64.7%). The rates of pregnancy were 65.8% for the group of patients with associated colorectal endometriosis and 57.8% for controls (P = 0.50). Age over 35 years was the only independent factor for which association with pregnancy rates approached the significance threshold (adjusted odds ratio 0.35, 95% CI 0.12-1, P = 0.06). LIMITATIONS, REASONS FOR CAUTION The study sample size may be insufficient to reveal statistically significant differences related to risk factors which have low impact on the probability of recurrence and pregnancy. Data on ovarian reserve before and after the procedure was not available in all patients, which would have added to our results and the discussion about treatment of endometrioma in general. WIDER IMPLICATIONS OF THE FINDINGS Concomitant management of colorectal endometriosis does not impact either risk of recurrences or the probability of pregnancy in women having benefited from ovarian endometrioma ablation using plasma energy. Moreover, surgical management of colorectal and ovarian endometriosis may allow spontaneous conception in one out of three patients, thus reducing expenses related to ART management.

Full-Thickness Disc Excision in Deep Endometriotic Nodules of the Rectum: A Prospective Cohort.

BACKGROUND: To date, a majority of patients presenting with large endometriosis of the rectum are managed worldwide by colorectal resection. However, postoperative rectal function may be impacted by radical rectal surgery. OBJECTIVE: The purpose of this study was to assess the postoperative outcomes of patients with rectal endometriosis who are managed by full-thickness disc excision and to compare outcomes of the 2 procedures using a transanal approach. DESIGN: This was a prospective study. SETTINGS: The study was conducted at a university hospital. PATIENTS: Fifty patients with colorectal endometriosis that was managed by disc excision between June 2009 and November 2014 were included in the study. INTERVENTIONS: The procedure included laparoscopic deep shaving, followed by full-thickness disc excision to remove the shaved rectal area. Disc excision was performed using a semicircular transanal stapler (the Rouen technique) in 20 patients, an end-to-end anastomosis circular transanal stapler in 28 patients, and transvaginal excision in 2 patients. MAIN OUTCOMES MEASURES: Preoperative and postoperative assessments of pelvic symptoms and digestive function using standardized gastrointestinal questionnaires were the main measures. RESULTS: The largest diameter of specimens achieved was significantly higher using the Rouen technique (58 ± 9 mm) than the end-to-end anastomosis stapler (34 ± 6 mm). Two rectovaginal fistulas were recorded (4%), and 8 patients presented with transitory bladder voiding (16%). Median postoperative values for the Gastrointestinal Quality of Life Index and the Knowles-Eccersley-Scott-Symptom Questionnaire improved progressively 1 and 3 years after surgery. For patients intending to get pregnant, the cumulative pregnancy rate was 80%, and 63% of pregnancies were spontaneous. LIMITATIONS: The study sample size is small and the design is not comparative; however, direct comparison of patients managed by disc excision and colorectal resection would be inappropriate, because of differences regarding nodule localization and size. CONCLUSIONS: Disc excision is a valuable alternative to colorectal resection in selected patients presenting with rectal endometriosis, achieving better preservation of rectal function. The Rouen technique allows for successful removal of large nodules of the low and midrectum, with favorable postoperative outcomes. (See video abstract, http://links.lww.com/DCR/A208.)

Are digestive symptoms in women presenting with pelvic endometriosis specific to lesion localizations? A preliminary prospective study

STUDY QUESTION What are the types and frequency of digestive symptoms in patients with different localizations of pelvic endometriosis and which specific symptoms are related to rectal stenosis? SUMMARY ANSWER There is a high prevalence of digestive complaints in women presenting with superficial pelvic endometriosis and deep endometriosis sparing the rectum. WHAT IS KNOWN ALREADY Women presenting with pelvic endometriosis frequently report gastrointestinal complaints of increased intensity during menstruation, which are not necessarily linked to the infiltration of the disease into the rectal wall. Even though intrarectal protrusion of the nodule can have an impact on bowel movement, only a minority of women with rectal nodules seemed to be concerned by significant narrowing of the rectum. STUDY DESIGN AND SIZE This three-arm cohort prospective study included 116 women and was carried out over 22 consecutive months. PARTICIPANTS, SETTING AND METHODS Prospective recording of data was performed for women treated for Stage 1 endometriosis involving the Douglas pouch (n = 21), deep endometriosis without digestive infiltration (n = 42) and deep endometriosis infiltrating the rectum (n = 53). Patient characteristics, pelvic pain and data from preoperative standardized questionnaires The Gastrointestinal Quality of Life Index (GIQLI), the Knowles-Eccersley-Scott-Symptom Questionnaire (KESS) and the MOS 36-Item Short-Form Health Survey (SF-36) were compared according to endometriosis localization. MAIN RESULTS The values of total KESS and total GIQLI score were comparable for the three groups, as were a majority of the digestive complaints. Women presenting with rectal endometriosis were more likely to report an increase in intensity and length of dysmenorrhoea, while deep dyspareunia appeared to be more severe in women with superficial endometriosis. Women presenting with rectal endometriosis were more likely to present cyclic defecation pain (67.9%), cyclic constipation (54.7%) and a significantly longer stool evacuation time, although these complaints were also frequent in the other two groups (38.1 and 33.3% in women with Stage 1 endometriosis and 42.9 and 26.2% in women with deep endometriosis without digestive involvement, respectively). No independent clinical factor was found to be related to infiltration of the rectum by deep endometriosis. Among women with rectal endometriosis, only 26.4% presented with rectal stenosis. These women were significantly more likely to report constipation, defecation pain, appetite disorders, longer evacuation time and increased stool consistency without laxatives. LIMITATIONS Patients treated for pelvic endometriosis in a tertiary referral centre may not be representative of the general endometriosis population presenting with those lesions. Statistically significant differences were revealed between the three groups; however, the results were based on a small number of subjects, which carries an inherent risk of type II error particularly when comparing variables with closed values. WIDER IMPLICATIONS OF THE FINDINGS In women presenting with pelvic endometriosis, it seems likely that various digestive symptoms are the consequence of cyclic inflammatory phenomena leading to irritation of the digestive tract, rather than to actual infiltration of the disease itself into the rectum, with the exception of a limited number of cases where the disease leads to rectal stenosis. STUDY FUNDING/COMPETING INTEREST The North-West Inter Regional Female Cohort for Patients with Endometriosis (CIRENDO) is financed by the G4 Group (The University Hospitals of Rouen, Lille, Amiens and Caen).
