Para-aortic lymph node metastasis detected intraoperatively by systematic frozen section examination in pancreatic head adenocarcinoma: is resection improving the prognosis?

BACKGROUND: This study aimed to evaluate the controversial benefit of a pancreaticoduodenectomy (PD) in patients with PALN metastasis intraoperatively detected by systematic frozen section examination in pancreatic adenocarcinoma. METHODS: PALN intraoperative examination by frozen section was systematically performed from January 2006 to February 2018 prior to performing PD for pancreatic adenocarcinoma. Until June 2012, PALN + patients still underwent PD (PALN+/PD group) in the framework of a prospective study. Since July 2012, PALN+ was considered as contraindicating the planned PD (PALN+/No-PD group). Post-operative morbidity and survival were compared between these two groups. RESULTS: Of the 32 PALN + patients intraoperatively detected, the first 13 underwent a PD, while the last 19 did not undergo resection. Seven patients (54%) among 13 PALN+/PD patients developed a post-operative complication against 3 (16%) among 19 PALN+/No-PD patients (p = 0.049). The median length of stay was 5 days longer for PALN+/PD patients (p = 0.001). The median survival did not differ between PALN+/No-PD and PALN+/PD groups (respectively 13.4 months (95%CI:7.6-19.3) and 11.5 months (95%CI:5.9-17.1), p = 0.471). No patient was alive 4 years after surgery in both the PALN+/No-PD or PALN+/PD groups. CONCLUSION: In case of PALN detected intraoperatively in pancreatic adenocarcinoma, PD does not improve survival compared to current palliative treatment.

Postoperative Peritonitis After Digestive Tract Surgery: Surgical Management and Risk Factors for Morbidity and Mortality, a Cohort of 191 Patients.

BACKGROUND: Postoperative peritonitis (POP) following gastrointestinal surgery is associated with significant morbidity and mortality, with no clear management option proposed. The aim of this study was to report our surgical management of POP and identify pre- and perioperative risk factors for morbidity and mortality. METHODS: All patients with POP undergoing relaparotomy in our department between January 2004 and December 2013 were included. Pre- and perioperative data were analyzed to identify predictors of morbidity and mortality. RESULTS: A total of 191 patients required relaparotomy for POP, of which 16.8% required >1 reinterventions. The commonest cause of POP was anastomotic leakage (66.5%) followed by perforation (20.9%). POP was mostly treated by anastomotic takedown (51.8%), suture with derivative stoma (11.5%), enteral resection and stoma (12%), drainage of the leak (8.9%), stoma on perforation (8.4%), duodenal intubation (7.3%) or intubation of the leak (3.1%). The overall mortality rate was 14%, of which 40% died within the first 48 h. Major complications (Dindo-Clavien > 2) were seen in 47% of the cohort. Stoma formation occurred in 81.6% of patients following relaparotomy. Independent risk factors for mortality were: ASA > 2 (OR = 2.75, 95% CI = 1.07-7.62, p = 0.037), multiorgan failure (MOF) (OR = 5.22, 95% CI = 2.11-13.5, p = 0.0037), perioperative transfusion (OR = 2.7, 95% CI = 1.05-7.47, p = 0.04) and upper GI origin (OR = 3.55, 95% CI = 1.32-9.56, p = 0.013). Independent risk factors for morbidity were: MOF (OR = 2.74, 95% CI = 1.26-6.19, p = 0.013), upper GI origin (OR = 3.74, 95% CI = 1.59-9.44, p = 0.0034) and delayed extubation (OR = 0.27, 95% CI = 0.14-0.55, p = 0.0027). CONCLUSION: Mortality following POP remains a significant issue; however, it is decreasing due to effective and aggressive surgical intervention. Predictors of poor outcomes will help tailor management options.

Hartmann's reversal after colonic perforation or anastomosis leakage, is it the same procedure? A retrospective study of 150 patients.

PURPOSE: The high morbidity rates reported might influence surgeons' decisions of whether to perform Hartmann's reversal (HR). Our aim was to report the results of HR after "primary" Hartmann's procedure (HP) or in redo surgery for failed anastomosis. METHODS: All patients operated between 2007 and 2015 were included. Data and postoperative course were obtained from a review of medical records and databases. RESULTS: One hundred fifty patients (age 60, range (20-91) years, 62% male) were included. Eighty-six patients (57%) were ASA ≥ 2. HP was mostly performed for diverticulitis (29.3%) and anastomotic leakage (24%). HR was possible in 145(97%) patients including six with previous failed attempt. Overall morbidity was 22.7% including 11.7% severe complications (Dindo 3-4). Operative blood loss and Charlson comorbidity index were the only significant risk factor for postoperative pelvic complications (p = 0.03; p = 0.0002, respectively). CONCLUSIONS: In a colorectal tertiary center, HR was feasible in 97% with a low morbidity and a 3.4% anastomotic leakage rate.

Female sexual function and fertility after ileal pouch-anal anastomosis.

PURPOSE: A potential complication in women after ileal pouch-anal anastomosis (IPAA) is sexual impairment and reduced fertility. The aim was to evaluate sexual function and fertility after IPAA. METHODS: All female patients who underwent an IPAA between 2004 and 2013 were retrospectively included. Sexual function, fertility, and continence were explored by the female sexual function index (FSFI), telephonic interview, and Wexner's score. RESULTS: Among 127 women included, 93 responded to the questionnaires (73.2%). Seventy five were sexually active, and 48 (64%) had normal sexual function (FSFI > 26). In univariate analysis, there was a significant relationship between ulcerative colitis (p = 0.0161), age > 40 years (p = 0.01311), number of bowel movements (p = 0.0238), nocturnal pouch activity (p = 0.0094), use of loperamide (p = 0.0283), and existence of sexual dysfunction. After multivariate analysis, age and nocturnal pouch activity were associated with a worse sexual function (p = 0.0235, OR = 3.3 (1.2-9.9) and p = 0.0094, OR = 4.1 (1.4-13.5)). Of 16 patients who wished to have children, 10 (63%) became pregnant without recourse to in vitro fertilization, of whom 3 had two or more pregnancies. In total, there were 13 children born after IPAA. The mean time between the first pregnancy and surgery was 24.8 ± 22 months. At 12 and 24 months after cessation of contraception, 57 and 67% had at least one pregnancy. CONCLUSIONS: While sexual function is impaired in a limited number of patients, the impact of surgery can be regarded as modest. Age and nocturnal pouch activity were some independent factors of worse sexual function. The risk of infertility should not preclude consideration of IPAA as a treatment option.

[Diagnosis and treatment of an intestinal obstruction]. / Occlusion intestinale, du diagnostic au traitement.

Intestinal obstruction, revealed by obstruction syndrome, is defined by the cessation of the bowel function whatever the cause. Bowel obstructions are one of the most frequent reasons for hospitalisation in digestive system surgery. They represent a surgical emergency. Diagnosis must enable the obstruction to be confirmed and its mechanisms and location to be specified. The treatment must always include restoring water-electrolyte balance, particularly in elderly people.

Is ileostomy mandatory for ileal pouch-anal anastomosis? A propensity matched analysis of 388 procedures.

BACKGROUND: Restorative proctocolectomy with ileal-pouch-anal anastomosis is the standard treatment for patients with ulcerative colitis or familial adenomatous polyposis. This procedure has undergone many changes and varies in 1, 2, or 3 stages. A diverting ileostomy can be created with the aim of reducing the consequence of an anastomotic leakage; however, its use is still unknown. METHOD: The value of defunctioning ileostomy was studied in a population of 388 patients undergoing restorative proctocolectomy with ileal-pouch-anal anastomosis between 2005 and 2017. Leakage rate and postoperative morbidity were assessed. Patients were matched on a propensity score using the following criteria: American Society of Anesthesiologists score, body mass index, diagnosis, surgical approach, and year. RESULTS: Two hundred and three ileal-pouch-anal anastomosis for ulcerative colitis and 185 for familial adenomatous polyposis were performed representing 165 1-stage (61.6%), 79 classic 2-stage, 74 modified 2-stage, and 70 3-stage procedures. Regardless of the surgical strategy adopted, there were no significant differences in postoperative morbidity (P = .416), leakage rate (P = .369), and reoperation (P = .237), whether a diverting ileostomy was performed or not. After propensity score matching, there was no significant difference in postoperative morbidity (P = .363), leakage rate (P = .247), or reoperation (P = .243). The rate of persistent ileostomy at 1 year was higher in cases of classic 2-stage or 3-stage procedures (P = .036). CONCLUSION: After propensity score matching, defunctioning ileostomy for ileal-pouch-anal anastomosis does not reduce leakage rate or postoperative morbidity, independent of the surgical strategy. Systematic ileostomy for ileal-pouch-anal anastomosis is probably not justified, and its place should be redefined in a randomized trial.

Tunica vaginalis flap for urethrocutaneous fistula repair after proximal and mid-shaft hypospadias surgery: A 12-year experience.

INTRODUCTION: Fistulas are a common complication of hypospadias surgery; they are more frequent after mid-shaft and posterior hypospadias repair. Surgical treatment of fistula still remains challenging with a significant failure rate. The basic principle is to add layers between skin and neourethra in order to decrease the incidence of recurrent urethrocutaneous fistula (UCF). We report our experience of UCF repair using a vascularized tunica vaginalis flap (TVF) after posterior and mid-shaft hypospadias surgery. MATERIAL AND METHODS: A retrospective review of all patients operated on using TVF for UCF in our institution between December 2005 and July 2017 was performed. RESULTS: Among 36 cases, TVF was used at a first attempt in 22 patients; 14 children had a prior attempt to close the fistula, and four of them had two surgeries before TVF repair. UCF was respectively penoscrotal (n = 3, 8%), posterior (n = 19, 53%), midshaft (n = 9, 25%) and anterior (n = 5, 14%). The size of the fistula was more than 5 mm in 26 patients. The UCF was treated successfully in every case after one single procedure. In the three children with two fistulas, both fistulas were successfully treated by the same TVF. After an average follow-up time of 45 months there was no recurrence of the initial UCF. In four cases of undescended testis, it was possible to dissect the flap through an inguinal incision and perform an orchydopexy in the same time. One patient presented a testicular atrophy after undescended testis surgery. DISCUSSION: Area review of published series shows excellent results in UCF repair including recurrent fistula (Table). TVF can aspire to some advantages with regard to a dartos flap (DF). First of all, a nearly 2.5-fold lower incidence of fistula after fistula repair with TVF than with DF (5.1% vs. 12.2%) has been shown. Secondly, TVF allows treating multiple fistulas, and can also be brought to the anterior part of the penis until the balano preputial furrow, allowing curing anterior fistula. Furthermore, it doesn't lead to aesthetic complications such as penile rotation or distal skin necrosis, which can occur during DF procedures. CONCLUSION: TVF is a simple and reproductive technique for UCF repair, with a high success rate. The risk of testicular atrophy has to be considered in case of associated undescended testis surgery, and careful attention must be given to the TVF dissection. This technique should be considered as first choice treatment for any UCF.

Day Surgery for Acute Appendicitis in Adults: A Prospective Series of 102 Patients.

AIM: To report the results of a consecutive series of day surgery appendectomy (DSA) for acute appendicitis. METHODS: Selection criteria for DSA were as follows: body mass index<28 kg/m, white cell count <15,000/mL, C-reactive protein<30 mg/L, no radiological signs of perforation, and appendix diameter ≤10 mm. All patients with radiologically proven appendicitis and 4 or 5 criteria were proposed for DSA and prospectively included. RESULTS: A total of 102 patients (female=39.2%) were operated between January 1, 2013 and January 5, 2015 with a median age of 29.5 years [interquartile range (IQR), 23 to 37 y]. Diagnosis was mainly supported by computed tomographic scan (75.5%). About 60 patients (59%) were reconvened on the next morning for surgery with oral antibiotics. The median operative time was 40 minutes (IQR, 30 to 52 min), and 92 (90%) patients were discharged on day 0 after a postoperative period of 5h:12min (IQR, 4h:14min to 6h:33min). The overall median hospital length of stay was 8h:04min (IQR, 6h:46min to 10h:23min). Surgical morbidity was 6.9% (n=7), with 1.9% (n=2) major complications. CONCLUSIONS: DSA is a safe procedure for selected patients; it reduces the hospital length of stay without increasing morbidity.

Clinical relevance of KRAS-mutated subclones detected with picodroplet digital PCR in advanced colorectal cancer treated with anti-EGFR therapy.

PURPOSE: KRAS mutations are predictive of nonresponse to anti-EGFR therapies in metastatic colorectal cancer (mCRC). However, only 50% of nonmutated patients benefit from them. KRAS-mutated subclonal populations nondetectable by conventional methods have been suggested as the cause of early progression. Molecular analysis technology with high sensitivity and precision is required to test this hypothesis. EXPERIMENTAL DESIGN: From two cohorts of patients with mCRC, 136 KRAS, NRAS, and BRAF wild-type tumors with sufficient tumor material to perform highly sensitive picodroplet digital PCR (dPCR) and 41 KRAS-mutated tumors were selected. All these patients were treated by anti-EGFR therapy. dPCR was used for KRAS or BRAF mutation screening and compared with qPCR. Progression-free survival (PFS) and overall survival (OS) were analyzed according to the KRAS-mutated allele fraction. RESULTS: In addition to the confirmation of the 41 patients with KRAS-mutated tumors, dPCR also identified KRAS mutations in 22 samples considered as KRAS wild-type by qPCR. The fraction of KRAS-mutated allele quantified by dPCR was inversely correlated with anti-EGFR therapy response rate (P < 0.001). In a Cox model, the fraction of KRAS-mutated allele was associated with worse PFS and OS. Patients with less than 1% of mutant KRAS allele have similar PFS and OS than those with wild-type KRAS tumors. CONCLUSIONS: This study suggests that patients with mCRC with KRAS-mutated subclones (at least those with a KRAS-mutated subclones fraction lower or equal to 1%) had a benefit from anti-EGFR therapies.

Feasibility of laparoscopic restorative proctocolectomy without diverting stoma.

AIM: Restorative proctocolectomy performed before the advent of laparoscopy had evolved to frequently omit a diverting stoma. Our aim was to assess the impact of a diverting stoma on postoperative outcomes following laparoscopic restorative proctocolectomy. METHOD: Data on all patients undergoing a laparoscopic restorative proctocolectomy at our institution were prospectively collated in a database. RESULTS: Between November 2004 and February 2010, 71 patients (38 females) underwent laparoscopic restorative proctocolectomy. Indications included familial adenomatous polyposis (n=34), ulcerative colitis (n=35), indeterminate colitis (n=1) and Lynch syndrome (n=1). Laparoscopic restorative proctocolectomy was performed as a one-stage procedure in 49 patients, and after a sub-total colectomy in 22. Seven patients in each group underwent the formation of a diverting stoma. Nine patients required conversion to open surgery. Sixteen patients experienced at least one postoperative complication. The postoperative morbidity was 29% (n=4/14) and 21% (n=12/21) in patients with and without a stoma (p=0.8), and the rate of fistula was 21% and 5%, respectively (p=0.08). Seven percent of patients with a stoma and 16% without stoma had an intra-abdominal collection (p=0.7). Nine patients required reoperation. The reoperation rate was not influenced by the presence or absence of a diverting stoma. CONCLUSION: Laparoscopic restorative proctocolectomy can be performed safely without a diverting stoma in selected patients.
