Use of fluorescence imaging and indocyanine green during laparoscopic cholecystectomy: Results of an international Delphi survey. Surgery 2022; 172:S21-S28. [PMID: 36427926 DOI: 10.1016/j.surg.2022.07.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2022] [Revised: 06/25/2022] [Accepted: 07/12/2022] [Indexed: 11/23/2022]
Abstract
BACKGROUND Published empirical data have increasingly suggested that using near-infrared fluorescence cholangiography during laparoscopic cholecystectomy markedly increases biliary anatomy visualization. The technology is rapidly evolving, and different equipment and doses may be used. We aimed to identify areas of consensus and nonconsensus in the use of incisionless near-infrared fluorescent cholangiography during laparoscopic cholecystectomy. METHODS A 2-round Delphi survey was conducted among 28 international experts in minimally invasive surgery and near-infrared fluorescent cholangiography in 2020, during which respondents voted on 62 statements on patient preparation and contraindications (n = 12); on indocyanine green administration (n = 14); on potential advantages and uses of near-infrared fluorescent cholangiography (n = 18); comparing near-infrared fluorescent cholangiography with intraoperative x-ray cholangiography (n = 7); and on potential disadvantages of and required training for near-infrared fluorescent cholangiography (n = 11). RESULTS Expert consensus strongly supports near-infrared fluorescent cholangiography superiority over white light for the visualization of biliary structures and reduction of laparoscopic cholecystectomy risks. It also offers other advantages like enhancing anatomic visualization in obese patients and those with moderate to severe inflammation. Regarding indocyanine green administration, consensus was reached that dosing should be on a milligrams/kilogram basis, rather than as an absolute dose, and that doses >0.05 mg/kg are necessary. Although there is no consensus on the optimum preoperative timing of indocyanine green injections, the majority of participants consider it important to administer indocyanine green at least 45 minutes before the procedure to decrease the light intensity of the liver. CONCLUSION Near-infrared fluorescent cholangiography experts strongly agree on its effectiveness and safety during laparoscopic cholecystectomy and that it should be used routinely, but further research is necessary to establish optimum timing and doses for indocyanine green.

Abstract
Abstract
Background
20–30% of patients operated for inguinal hernia will present early postoperative pain (EPP) which is, after the organizational causes, the first cause of conversion from ambulatory to traditional hospitalization. The objective of this study was to evaluate the interest of a parietal prosthesis (Cyclomesh ™) soaked with ropivacaine in the management of EPP.
Materials and Methods
This is a randomized, phase III, comparative superiority, double-blind, international multicentre study. From October 2019 to February 2022, 290 patients underwent surgery for inguinal hernia with placement of a ropivacaine or saline soaked parietal prosthesis. The primary endpoint was the H6 coughing pain assessment (EVA).
Results
The intention to treat population (ITTp) was composed of 150 patients in the ropivacaine group and 140 in the placebo group, for the per-protocol population (PPp) it was 125 and 115. The prosthesis type had no significant effect on H6 coughing pain, either for the ITTp (3.3 vs 3.2, p=0.12) or the PPp (3.3 vs 3.7, p=0.15). The ropivaciane soaked prosthesis resulted in a decrease in the overall pain at H2 (2.3 vs 3.2, p<0.0001), H4 (2.3 vs 3.1, p<0.0001) and H6 (2.3 vs 2.7, p=0.0039). Regarding painkillers consumption, postoperative complications and number of ambulatory conversions, there was no difference between the two groups.
Conclusion
The placement of a parietal prosthesis (Cyclomesh ™) soaked with ropivacaine did not reduce the H6 coughing pain but allowed a decrease in the overall pain over the first 6 hours after surgery and could simplify the management of patients.

Long-term outcomes of Hartmann's procedure versus primary anastomosis for generalized peritonitis due to perforated diverticulitis: follow-up of a prospective multicenter randomized trial (DIVERTI). Int J Colorectal Dis 2021; 36:2159-2164. [PMID: 34086087 DOI: 10.1007/s00384-021-03962-2] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 05/23/2021] [Indexed: 02/04/2023]
Abstract
BACKGROUND Surgical management of Hinchey III and IV diverticulitis involves Hartmann's procedure (HP) or primary resection anastomosis (PRA) with or without fecal diversion. These procedures were evaluated in four randomized controlled trials. Early results from these trials demonstrated similar rates of complications but higher rates of colonic restoration after PRA than HP. Long-term follow-up has not been reported to date. The aim of this study was to analyze long-term outcomes and quality of life (QoL) in patients previously enrolled in a prospective randomized trial comparing HP and PRA for generalized peritonitis due to perforated diverticulitis (DIVERTI trial). STUDY DESIGN Follow-up data were available for 78 of 102 patients. Demographic data, incisional hernia rate, need for additional surgery related to the primary procedure, and QoL were recorded. RESULTS The overall survival rate was 76% and did not differ between the two groups. Incisional hernia was reported in 21 (52%) patients in the HP arm and in 11 (29%) patients in the PRA arm (p = 0.035). The HP arm demonstrated significantly lower SF-36 physical and mental component scores. The mean general QoL (EQ-VAS) and mean EQ-5D index scores were better after PRA than after HP, but this difference was not statistically significant. The results of GIQLI, which measures intestine-specific QOL, did not differ between the two groups. CONCLUSIONS This follow-up study with a median follow-up time of > 9 years among living patients indicates that PRA for perforated diverticulitis is associated with fewer long-term complications and better QoL than HP. PRA significantly reduced the incisional hernia rate and the need for reoperation. Long-term survival was not jeopardized by the PRA approach. Future studies are needed to address the utility of protective stoma.

Abstract
BACKGROUND The relevance of laparoscopic resection of intrahepatic cholangiocarcinoma (ICC) remains debated. The aim of this study was to compare laparoscopic (LLR) and open (OLR) liver resection for ICC, with specific focus on textbook outcome and lymph node dissection (LND). METHODS Patients undergoing LLR or OLR for ICC were included from two French, nationwide hepatopancreatobiliary surveys undertaken between 2000 and 2017. Patients with negative margins, and without transfusion, severe complications, prolonged hospital stay, readmission or death were considered to have a textbook outcome. Patients who achieved both a textbook outcome and LND were deemed to have an adjusted textbook outcome. OLR and LLR were compared after propensity score matching. RESULTS In total, 548 patients with ICC (127 LLR, 421 OLR) were included. Textbook-outcome and LND completion rates were 22.1 and 48.2 per cent respectively. LLR was independently associated with a decreased rate of LND (odds ratio 0.37, 95 per cent c.i. 0.20 to 0.69). After matching, 109 patients remained in each group. LLR was associated with a decreased rate of transfusion (7.3 versus 21.1 per cent; P = 0.001) and shorter hospital stay (median 7 versus 14 days; P = 0.001), but lower rate of LND (33.9 versus 73.4 per cent; P = 0.001). Patients who underwent LLR had lower rate of adjusted TO completion than patients who had OLR (6.5 versus 17.4 per cent; P = 0.012). CONCLUSION The laparoscopic approach did not substantially improve quality of care of patients with resectable ICC.

Abstract
(1) Background: preoperative biliary drainage before pancreaticoduodenectomy (PD) is associated with bacterial biliary contamination (>85%) and a significant increase in global and infectious complications. In view of the lack of published data, the aim of our study was to investigate the impact of fungal biliary contamination after biliary drainage on the complication rate after PD. (2) Methods: a multicentric retrospective study that included 224 patients who underwent PD after biliary drainage with intraoperative biliary culture. (3) Results: the global rate of positive intraoperative biliary sample was 92%. Respectively, the global rate of biliary bacterial contamination and the rate of fungal contamination were 75% and 25%, making it possible to identify two subgroups: bacterial contamination only (B+, n = 154), and bacterial and fungal contamination (BF+, n = 52). An extended duration of preoperative drainage (62 vs. 49 days; p = 0.08) increased the risk of fungal contamination. The overall and infectious complication rates were not different between the two groups. In the event of postoperative infectious or surgical complications, the infectious samples taken did not reveal more fungal infections in the BF+ group. (4) Conclusions: fungal biliary contamination, although frequent, does not seem to increase the rate of global and infectious complications after PD, preceded by preoperative biliary drainage.

The value of post-operative antibiotic therapy after laparoscopic appendectomy for complicated acute appendicitis: a prospective, randomized, double-blinded, placebo-controlled phase III study (ABAP study). Trials 2020; 21:451. [PMID: 32487213 PMCID: PMC7268648 DOI: 10.1186/s13063-020-04411-1] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2019] [Accepted: 05/14/2020] [Indexed: 12/31/2022] Open
Abstract
BACKGROUND Approximately 30% of appendectomies are for complicated acute appendicitis (CAA). With laparoscopy, the main post-operative complication is deep abscesses (12% of cases of CAA, versus 4% for open surgery). A recent cohort study compared short and long courses of postoperative antibiotic therapy in patients with CAA. There was no significant intergroup difference in the post-operative complication rate (12% of organ/space surgical site infection (SSI)). Moreover, antibiotic therapy is increasingly less indicated for other situations (non-complicated appendicitis, post-operative course of cholecystitis, perianal abscess), calling into question whether post-operative antibiotic therapy is required after laparoscopic appendectomy for CAA. METHODS/DESIGN This study is a prospective, multicenter, parallel-group, randomized (1:1), double-blinded, placebo-controlled, phase III non-inferiority study with blind evaluation of the primary efficacy criterion. The primary objective is to evaluate the impact of the absence of post-operative antibiotic therapy on the organ/space surgical site infection (SSI) rate in patients presenting with CAA (other than in cases of generalized peritonitis). Patients in the experimental group will receive at least one dose of preoperative and perioperative antibiotic therapy (2 g ceftriaxone by intravenous injection every 24 h up to the operation) and metronidazole (500 mg by intravenous injection every 8 h up to the operation) and, in the post-operative period, a placebo for ceftriaxone (2 g/24 h in one intravenous injection) and a placebo for metronidazole (1500 mg/24 h in three intravenous injections, for 3 days). In the control group, patients will receive at least one dose of preoperative and perioperative antibiotic therapy (2 g ceftriaxone by intravenous injection every 24 h up to the operation) and metronidazole (500 mg by intravenous injection every 8 h up to the operation) and, in the post-operative period, antibiotic therapy (ceftriaxone 2 g/24 h and metronidazole 1500 mg/24 h for 3 days). In the event of allergy to ceftriaxone, it will be replaced by levofloxacin (500 mg/24 h in one intravenous injection, for 3 days). The expected organ space SSI rate is 12% in the population of patients with CAA operated on by laparoscopy. With a non-inferiority margin of 5%, a two-sided alpha risk of 5%, a beta risk of 20%, and a loss-to-follow-up rate of 10%, the calculated sample size is 1476 included patients, i.e., 738 per group. Due to three interim analyses at 10%, 25%, and 50% of the planned sample size, the total sample size increases to 1494 patients (747 per arm). TRIAL REGISTRATION Ethical authorization by the Comité de Protection des Personnes and the Agence Nationale de Sécurité du Médicament: ID-RCB 2017-00334-59. Registered on ClinicalTrials.gov (NCT03688295) on 28 September 2018.

Abstract
AIM The aim was to define risk factors for postoperative mortality in patients undergoing emergency surgery for obstructing colon cancer (OCC) and to propose a dedicated score. METHOD From 2000 to 2015, 2325 patients were treated for OCC in French surgical centres by members of the French National Surgical Association. A multivariate analysis was performed for variables with P value ≤ 0.20 in the univariate analysis for 30-day mortality. Predictive performance was assessed by the area under the receiver operating characteristic curve. RESULTS A total of 1983 patients were included. Thirty-day postoperative mortality was 7%. Multivariate analysis found five significant independent risk factors: age ≥ 75 (P = 0.013), American Society of Anesthesiologists (ASA) score ≥ III (P = 0.027), pulmonary comorbidity (P = 0.0002), right-sided cancer (P = 0.047) and haemodynamic failure (P < 0.0001). The odds ratio for risk of postoperative death was 3.42 with one factor, 5.80 with two factors, 15.73 with three factors, 29.23 with four factors and 77.25 with five factors. The discriminating capacity in predicting 30-day postoperative mortality was 0.80. CONCLUSION Thirty-day postoperative mortality after emergency surgery for OCC is correlated with age, ASA score, pulmonary comorbidity, site of tumour and haemodynamic failure, with a specific score ranging from 0 to 5.

Abstract
AIM In the presence of large bowel obstruction, the choice of treatment is determined by the patient's general status, the tumour characteristics and the perceived risk of caecal perforation. This study was designed to evaluate the predictive factors of impending caecal perforation, and also investigated the use of caecal volumetry. METHOD From January 2011 to June 2016, patients with obstructive distal colon cancer undergoing emergency laparotomy, for whom a pretreatment CT scan was available, were included in this retrospective, case-control, two-centre study. Two patient groups were defined: patients with and without impending caecal perforation. The primary end-point of the study was a determination of predictive factors for caecal perforation. RESULTS A total of 72 patients (45 men, 62.5%) were included. Univariate analysis revealed that the presence of pericaecal fluid (P < 0.0001), caecal pneumatosis (P < 0.0001), mean maximum caecal diameter (P = 0.001), mean caecal diameter at the ileocaecal junction (P = 0.0001) and mean caecal volume (P = 0.001) were associated with caecal perforation. Receiver operating characteristic curve analysis revealed that a caecal volume greater than 400 cm3 (P < 0.0001), a maximum caecal diameter > 9 cm (P = 0.002) and a caecal diameter at the ileocaecal junction > 7.5 cm (P = 0.001) were associated with impending caecal perforation. In multivariate analysis, only caecal volume > 400 cm3 (P = 0.001) was correlated with the risk of impending caecal perforation. CONCLUSION Caecal volumetry is an easy and useful tool to predict impending caecal perforation in patients with large bowel obstruction.

Abstract
INTRODUCTION Fecal appendicular peritonitis (FAP) is a poorly studied, rare form of acute appendicitis, corresponding to peritoneal inflammation with the presence of feces secondary to ruptured appendix. The purpose of this study was to describe FAP and to compare FAP with purulent appendicular peritonitis (PAP). PATIENTS AND METHODS This single-center, retrospective study was conducted in consecutive patients to compare the FAP group and the PAP group. The primary endpoint was the 30-day postoperative morbidity and mortality according to the Clavien-Dindo classification. The secondary endpoints were description and comparison of intraoperative data (laparoscopy rate, conversion rate, type of procedure and the mean operating time), and short-term outcomes (types of complications, length of stay, readmission rate, and reoperation rate), comparison of intraoperative bacteriological samples of FAP and PAP as well as the rate of resistance to amoxicillin and clavulanic acid, used as routine postoperative antibiotic therapy. RESULTS Between January 2006 and January 2016, 2.2% of appendectomies were performed for FAP. Patients of the FAP group reported a longer history of pain than patients of the PAP group (mean: 58 h [range: 24-120] vs 24 h [range: 6-504], p = 0.0001) and hyperthermia was more frequent in the FAP group than in the PAP group (72% vs 26%, p = 0.0001). Mean preoperative CRP was also higher in the FAP group than in the PAP group (110 mg/L [range: 67-468] vs 37.5 mg/L [range: 3.1-560], p = 0.007). Significantly less patients were operated by laparoscopy in the FAP group (89.7% vs 96.6%, p < 0.0001). Mean length of stay was significantly longer in the FAP group than in the PAP group (10 days [range: 3-24] vs 5 days [range: 1-32], p = 0.001). The overall 30-day complication rate was significantly higher in the FAP group than in the PAP group (62.1% vs 24.7%, p = 0.0005). The readmission rate was not significantly different between the two groups (14% vs 11.2%, p = 0.2), but the reoperation rate was higher in the FAP group than in the PAP group (31% vs 11%, p = 0.01). No significant difference was observed between the FAP and PAP groups in terms of the positive culture rate (75.9% vs 65.6%, p = 0.3). No significant difference was observed between the two groups in terms of resistance to amoxicillin and clavulanic acid (18.2% vs 20.5%, p = 0.8). CONCLUSION FAP is associated with significantly more severe morbidity compared to PAP. Clinicians must be familiar with this form of appendicitis in order to adequately inform their patients.

Abstract
BACKGROUND The aim of this study was to evaluate the results of major hepatectomies for metastasis in elderly colorectal cancer patients, for whom limited data exist in the literature. METHODS From January 2006 to January 2013, 3,034 patients underwent hepatectomy for colorectal liver metastasis in 32 French surgical centers. Repeat hepatectomies were excluded from the study. Based on a 1: 4 propensity score matching model, 42 patients aged ≥80 (OG) were matched with 168 patients <80 years (YG) in order to obtain 2 well-balanced and homogeneous groups with regards to therapy and prognostic factors. RESULTS The unmatched cohort consisted of 744 patients (OG: n = 42; YG: n = 702). After PS matching, there was no difference in terms of general morbidity, rates of Dindo-Clavien score ≥III (OG: 16% vs. YG: 21%, p = 0.663), surgical morbidity (OG: 16% vs. YG: 21%, p = 0.663), reoperation (OG:10% vs. YG: 5%, p = 0.263), 90-day mortality (OG: 0% vs. YG:2%, p = 1), and total median hospital stay (OG: 12 vs. YG: 12, p = 0.972). Both groups experienced similar 3- and 5-year overall survival (82 and 82% OG vs.78 and 67% YG) and disease-free survival (40 and 35% OG vs. 45 and 35% YG at 3 and 5 years). CONCLUSIONS No difference in perioperative and postoperative outcomes and disease-free and overall survival was found. Major hepatectomy in selected octogenarian patients is safe and feasible.

Between April 2005 and July 2016, patients with a confirmed gastric leak undergoing endoscopic treatment using a covered stent (CS) or double-pigtail stent (DPS) were included. The primary objective of the study was to assess overall costs of the stent types after primary sleeve gastrectomy. Secondary objectives were the cost-effectiveness of each stent type expressed as an incremental cost-effectiveness ratio (ICER); the incremental net benefit; the probability of efficiency, defined as the probability of being cost-effective at a threshold of €30 000, and identification of the key drivers of ICER derived from a multivariable analysis.
Results
One hundred and twelve patients were enrolled. The overall mean costs of gastric leak were €22 470; the mean(s.d.) cost was €24 916(12 212) in the CS arm and €20 024(3352) in the DPS arm (P = 0·018). DPS was more cost-effective than CS (ICER €4743 per endoscopic procedure avoided), with an incremental net benefit of €25 257 and a 27 per cent probability of efficiency. Key drivers of the ICER were the inpatient ward after diagnosis of gastric leak (surgery versus internal medicine), type of institution (private versus public) and duration of hospital stay per endoscopic procedure.
Conclusion
DPS for the treatment of gastric leak is more cost-effective than CS and should be proposed as the standard regimen whenever possible.

Feasibility, safety and efficacy of two-stage hepatectomy for bilobar liver metastases of colorectal cancer: a LiverMetSurvey analysis. HPB (Oxford) 2017; 19:396-405. [PMID: 28343889 DOI: 10.1016/j.hpb.2017.01.008] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/29/2016] [Revised: 12/29/2016] [Accepted: 01/04/2017] [Indexed: 12/12/2022]
Abstract
BACKGROUND The combination of liver resection and chemotherapy has become the standard of care for colorectal liver metastases (LM). The objective of the present study was to evaluate the impact of two-stage hepatectomy (TSH) on the long-term survival of patients with bilobar LM. METHODS We included adult (over-18) patients from the LiverMetSurvey registry with confirmed multiple colorectal LM and having undergone either one-stage hepatectomy or TSH with curative intent. The "TSH (2/2)" group (n = 625) comprised patients having completed both stages of TSH; the "TSH (1/2)" group (n = 244) comprised patients having undergone only the first stage of TSH; the "hepatectomy" group. The primary outcome criterion was the overall survival (OS). The secondary outcomes were the morbidity and mortality rates. RESULTS The 30- and 90-day mortality rates were respectively 3.8% and 9.3% in the TSH (2/2) group, 9.4% and 16.4% in the TSH (1/2) group, and 5.4% and 9.1% in the "hepatectomy" group. The three-year OS rate was 45% in the TSH (2/2) group, 30% in the TSH (1/2) group and 50.7% in the hepatectomy group. CONCLUSION The LiverMetSurvey registry's data indicate that TSH is associated with rather good long-term survival and acceptable morbidity and mortality rates.

Use of water-soluble contrast medium (gastrografin) does not decrease the need for operative intervention nor the duration of hospital stay in uncomplicated acute adhesive small bowel obstruction? A multicenter, randomized, clinical trial (Adhesive Small Bowel Obstruction Study) and systematic review. Surgery 2017; 161:1315-1325. [PMID: 28087066 DOI: 10.1016/j.surg.2016.11.026] [Citation(s) in RCA: 26] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2016] [Revised: 10/27/2016] [Accepted: 11/17/2016] [Indexed: 12/29/2022]
Abstract
BACKGROUND This study evaluated the association between oral gastrografin administration and the need for operative intervention in patients with presumed adhesive small bowel obstruction. METHODS Between October 2006 and August 2009, 242 patients with uncomplicated acute adhesive small bowel obstruction were included in a randomized, controlled trial (the Adhesive Small Bowel Obstruction Study, NCT00389116) and allocated to a gastrografin arm or a saline solution arm. The primary end point was the need for operative intervention within 48 hours of randomization. The secondary end points were the resection rate, the time interval between the initial computed tomography and operative intervention, the time interval between oral refeeding and discharge, risk factors for the failure of nonoperative management, in-hospital mortality, duration of stay, and recurrence or death after discharge. We performed a systematic review of the literature in order to evaluate the relationship between use of gastrografin as a diagnostic/therapeutic measure, the need for operative intervention, and the duration of stay. RESULTS In the gastrografin and saline solution arms, the rate of operative intervention was 24% and 20%, respectively, the bowel resection rate was 8% and 4%, the time interval between the initial computed tomography and operative intervention, and the time interval between oral refeeding and discharge were similar in the 2 arms. Only age was identified as a potential risk factor for the failure of nonoperative management. The in-hospital mortality was 2.5%, the duration of stay was 3.8 days for patients in the gastrografin arm and 3.5 days for those in the saline solution arm (P = .19), and the recurrence rate of adhesive small bowel obstruction was 7%. These results and those of 10 published studies suggest that gastrografin did not decrease either the rate of operative intervention (21% in the saline solution arm vs 26% in the gastrografin arm) or the number of days from the initial computed tomography to discharge (3.5 vs 3.5; P = NS for both). CONCLUSION The results of the present study and those of our systematic review suggest that gastrografin administration is of no benefit in patients with adhesive small bowel obstruction.

Impact of intraoperative blood transfusion on short and long term outcomes after curative hepatectomy for intrahepatic cholangiocarcinoma: a propensity score matching analysis by the AFC-IHCC study group. HPB (Oxford) 2017; 19:411-420. [PMID: 28122668 DOI: 10.1016/j.hpb.2017.01.001] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/19/2016] [Revised: 12/22/2016] [Accepted: 01/01/2017] [Indexed: 01/28/2023]
Abstract
BACKGROUND The impact of intraoperative blood transfusion (IBT) on outcomes following intrahepatic cholangiocarcinoma (IHCC) resection remains to be ascertained. METHODS All consecutive IHCC resected were analyzed. A first cohort (n = 569) was used for investigating short-term outcomes (morbidity and mortality). A second cohort (n = 522) excluding patients dead within 90 days of surgery was analyzed for exploring overall survival (OS) and disease free survival (DFS). Patients who received IBT were compared to those who did not, after using a propensity score matching (PSM) method. RESULTS Among 569 patients, 90-day morbidity and mortality rates were 47% (n = 269) and 8% (n = 47). After PSM, 208 patients were matched. There was an association between IBT and increased overall morbidity and severe morbidity (p = 0.010). However, IBT did not impact 90-day mortality rate (p > 0.999). Regarding long-term outcomes analysis in the second cohort (n = 522), 5-year OS and DFS rates were 39% and 25%. Using PSM, 196 patients were matched and no association between IBT and OS or DFS was found (p = 0.333 and p = 0.491). CONCLUSIONS IBT is associated with an increased risk of morbidity but does not impact on long-term outcomes. Need for IBT should be considered as a surrogate of advanced disease requiring complex resection. Still, restricted transfusion policy should remain advocated for IHCC resection.

Abstract
INTRODUCTION The implementation of enhanced recovery programmes after elective colorectal surgery has dramatically reduced the length of stay. The objective of this study was to assess the selection of good candidates for short post-operative stay (GCSS) in the context of stoma closure. METHODS Between January 2011 and December 2014, 222 patients were included in the present retrospective, single-center study. The primary endpoint was the proportion of GCSS. We also identified factors associated with GCSS status and built a predictive score. RESULTS The study population was predominantly male (n = 122, 55%). 60% of the patients had undergone ileostomy and 85% had undergone hand-sewn anastomosis. The postoperative ileus rate was 5% and the readmission rate was 3.5%. 41% (n = 92) of the study population were considered to be GCSS. In a multivariate analysis, age under 50 (odds ratio (OR) [95% confidence interval (CI)] = 2.8 [1.2-5.6], p = 0.008), the absence of vascular comorbidities (OR [95%CI] = 3.2 [1.3-12.3]; p = 0.006) and stapled anastomosis (OR: 4.2, 95%CI: 1.1-17.3, p = 0.03) were associated with GCSS status. Predictive scores of 0, 1, 2, and 3 were associated with GCSS rates of 20%, 18%, 44%, and 62%, respectively (p < 0.001). CONCLUSION In the context of stoma closure, 41% of patients were GCSS.

Abstract
BACKGROUND Postoperative ischaemic colitis (POIC) is a life-threatening vascular gastrointestinal condition. Serum procalcitonin (PCT) levels be of value in the detection of necrosis. AIMS To evaluate the correlation between serum PCT levels and the colonoscopic assessment of the severity of POIC. METHODS Between January 2007 and November 2014, 150 patients with POIC and PCT data were included in the study. The main outcome measure was the correlation between serum PCT and the colonoscopy-based assessment of the severity of POIC (according to Favier's classification: stage 1/2 without multi-organ failure vs. stage 2/3 with multi-organ failure). RESULTS Eighty-five percent of the stage 1 cases (n=22) had a serum PCT level ≤2μg/L; 63% (n=19) of the stage 2 cases with multi-organ failure had a PCT level between 4 and 8μg/L, and 70% (n=52) of the stage 3 cases had a PCT level ≥8μg/L. The PCT level was strongly correlated with the Favier stage (Spearman's rho: 0.701; p<0.0001). PCT levels were similar in stage 2 cases with multi-organ failure and in stage 3 cases (16.06μg/L vs. 7.79μg/L, respectively; p=0.35). CONCLUSION AND RELEVANCE Serum PCT is correlated with stage 2/3 POIC requiring surgery. If PCT ≥5μg/L, surgery should be considered.

Abstract
BACKGROUND The impact of morbidity on long-term outcomes following liver resection for intrahepatic cholangiocarcinoma is currently unclear. METHODS This was a retrospective analysis of all consecutive patients who underwent liver resection for intrahepatic cholangiocarcinoma with curative intent in 24 university hospitals between 1989 and 2009. Severe morbidity was defined as any complication of Dindo-Clavien grade III or IV. Patients with severe morbidity were compared with those without in terms of demographics, pathology, management, morbidity, overall survival, disease-free survival and time to recurrence. Independent predictors of severe morbidity were identified by multivariable analysis. RESULTS A total of 522 patients were enrolled. Severe morbidity occurred in 113 patients (21·6 per cent) and was an independent predictor of overall survival (hazard ratio 1·64, 95 per cent c.i. 1·21 to 2·23), as were age at resection, multifocal disease, positive lymph node status and R0 resection margin. Severe morbidity did not emerge as an independent predictor of disease-free survival. Independent predictors of time to recurrence included severe morbidity, tumour size, multifocal disease, vascular invasion and R0 resection margin. Major hepatectomy and intraoperative transfusion were independent predictors of severe morbidity. CONCLUSION Severe morbidity adversely affects overall survival following liver resection for intrahepatic cholangiocarcinoma.

Abstract
BACKGROUND Liver resection is the most effective treatment for intrahepatic cholangiocarcinoma. Recurrent disease is frequent; however, recurrence patterns are ill-defined and prognostic models are lacking. STUDY DESIGN A primary cohort of 189 patients who underwent resection for intrahepatic cholangiocarcinoma was used for recurrence patterns analysis within and after 24 months. Based on independent factors for disease-free survival identified in Cox regression analysis, preoperative and postoperative models were developed using a recursive partitioning method. Models were externally validated using a multicenter cohort of 522 resected patients (Association Française de Chirurgie intrahepatic cholangiocarcinoma study group). RESULTS Recurrence within 24 months most often involved the liver (82.7%), and most recurrences after 24 months were strictly extrahepatic (61.1%). In multivariable analysis of the primary cohort, independent preoperative factors for disease-free survival were tumor size and multifocality (based on imaging); tumor size, multifocality, vascular invasion, and lymph node metastases (based on pathology) were independent postoperative factors. The preoperative model allowed patient classification into low-risk and high-risk groups for recurrence. In the validation cohort (n = 522), high-risk patients had a greater likelihood of recurrence (hazard ratio = 2.17; 95% CI, 1.74-2.72; p < 0.001). The postoperative model included tumor size, vascular invasion, and positive nodal disease on pathology and classified patients in low-, intermediate-, and high-risk groups in the primary cohort. As compared with low-risk patients in the validation cohort, intermediate- and high-risk patients were more likely to experience recurrence (hazard ratio = 1.9; 95% CI, 1.41-2.47; p < 0.001 and hazard ratio = 2.99; 95% CI, 2.08-4.31; p < 0.001, respectively). CONCLUSIONS Recurrence patterns are time dependent. Both models as developed and validated in this study classified patients in distinct recurrence risk groups, which can guide treatment recommendations.

Abstract
Prophylactic drainage of the abdominal cavity after gastro-intestinal surgery is widely used. The rationale is that intra-abdominal drainage enhances early detection of complications (gastro-intestinal leakage, hemorrhage, bile leak), prevents collection of fluid or pus, reduces morbidity and mortality, and decreases the duration of hospital stay. However, dogmatic attitudes favoring systematic drain placement should be questioned. The aim of this review was to evaluate the evidence supporting systematic use of prophylactic abdominal drainage following gastrectomy, pancreatectomy, liver resection, and rectal resection. Based on this review of the literature: (i) there was no evidence in favor of intra-peritoneal drainage following total or sub-total gastrectomy with respect to morbidity-mortality, nor was it helpful in the diagnosis or management of leakage, however the level of evidence is low, (ii) following pancreatic resection, data are conflicting but, overall, suggest that the absence of drainage is prejudicial, and support the notion that short-term drainage is better than long-term drainage, (iii) after liver resection without hepatico-intestinal anastomosis, high level evidence supports that there is no need for abdominal drainage, and (iv) following rectal resection, data are insufficient to establish recommendations. However, results from the French multicenter randomized controlled trial GRECCAR5 (NCT01269567) should provide new evidence this coming year. Accumulating data support that systematic drainage of the abdominal cavity in digestive surgery is a non-beneficial and obsolete practice, except following pancreatectomy where the consensus appears to indicate the usefulness of short-term drainage. While the level of evidence is high for liver resections, new randomized controlled trials are awaited regarding gastric, pancreatic and rectal surgery.

Abstract
BACKGROUND Over the last two decades, many surgical teams have developed programs to treat peritoneal carcinomatosis with extensive cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (HIPEC). Currently, there are no specific recommendations for HIPEC procedures concerning environmental contamination risk management, personal protective equipment (PPE), or occupational health supervision. METHODS A survey of the institutional practices among all French teams currently performing HIPEC procedures was carried out via the French network for the treatment of rare peritoneal malignancies (RENAPE). RESULTS Thirty three surgical teams responded, 14 (42.4%) which reported more than 10 years of HIPEC experience. Some practices were widespread, such as using HIPEC machine approved by the European Community (100%), individualized or centralized smoke evacuation (81.8%), "open" abdominal coverage during perfusion (75.8%), and maintaining the same surgeon throughout the procedure (69.7%). Others were more heterogeneous, including laminar flow air circulation (54.5%) and the provision of safety protocols in the event of perfusate spills (51.5%). The use of specialized personal protective equipment is ubiquitous (93.9%) but widely variable between programs. CONCLUSION Protocols regarding cytoreductive surgery/HIPEC and the associated professional risks in France lack standardization and should be established.

Abstract
OBJECTIVES To compare the demographic characteristics and intra- and postoperative outcomes in elderly adults (≥75) with those of younger adults undergoing early (<5 days after onset of complaints) cholecystectomy. DESIGN Retrospective analysis from May 2010 to August 2012. SETTING Randomized, multicenter, clinical trial (ABCAL Study, NCT01015417). PARTICIPANTS Individuals with mild or moderate acute calculous cholecystitis (ACC) according to the Tokyo Guidelines (N=414; n=78 aged 75-94, median 82; n=336 aged 18-74, median 49). MEASUREMENTS Demographic characteristics and pre-, intra-, and postoperative data. RESULTS The elderly group was more likely to have an American Society of Anesthesiologists score of 3 or greater (62% vs 23%, P<.001), higher serum creatinine (103 vs 74 μmol/L, P<.001), and more-severe ACC (moderate ACC (62% vs 50%, P=.05), gangrenous cholecystitis (38% vs 15%, P=.001)) on preoperative imaging and confirmed intraoperatively. Ulcerated mucosa (76% vs 61%, P=.001) was significantly more frequent in the elderly group. Operative time, postoperative mortality, and postoperative infectious (18% vs 14%, P=.35) and noninfectious (9% vs 3%, P=.80) complications were similar between the two groups. Median length of stay (7.0 vs 5.0 days, P=.54) and readmission rate (15% vs 4%, P=.07) were not significantly higher in the elderly group. No significant difference was observed for the subgroup of participants aged 80 and older. CONCLUSION In this randomized trial that included a selected sample of older adults, there was no difference in major outcomes between elderly adults and their younger counterparts after early cholecystectomy. The findings are limited because important geriatric outcomes such as delirium and functional decline were not examined.

Abstract
BACKGROUND Ischemic and necrotic damages are complications of digestive diseases and require emergency management. Nevertheless, the decision to surgically manage could be delayed because of no sufficiently preoperative accurate marker of ischemia diagnosis, extension, and prognosis. METHODS The aim of this study was to assess the predictive value of serum procalcitonin (PCT) levels for diagnosing intestinal necrotic damages, their extension, and their prognosis in patients with ischemic disease including ischemic colitis and mesenteric infarction by a gray zone approach. Between January 2007 to June 2014, 128 patients with ischemic colitis and mesenteric infarction (codes K55.0 and K51.9) were operated, for whom data on PCT were available. We perform a retrospective, multicenter review of their medical records. Patients were divided into subgroups: ischemia (ID group) versus necrosis (ND group); the extension [focal (FD) vs. extended (ED)] and the vital status [deceased (D) vs. alive (A)]. RESULTS PCT levels were higher in the ND (n = 94; p = 0.009); ED (n = 100; p = 0.02); and D (n = 70; p = 0.0003) groups. With a gray zone approach, the predictive thresholds were (i) for necrosis 2.473 ng/mL, (ii) for extension 3.884 ng/mL, and (iii) for mortality 7.87 ng/mL. CONCLUSION In our population, PCT could be used as a marker of necrosis; especially in case of extended damages and reflects the patient's prognosis.

Abstract
INTRODUCTION As mortality and morbidity after a curative resection remains high, it is essential to identify pre-operative factors associated with an early death after a major resection. METHODS Between 1998 and 2008, we selected a population of 331 patients having undergone a major hepatectomy including segment I with a lymphadenectomy and a common bile duct resection for a proven hilar cholangiocarcinoma in 21 tertiary centres. The study's objective was to identify pre-operative predictors of early death (<12 months) after a resection. RESULTS The study cohort consisted of 221 men and 110 women, with a median age of 61 years (range: 24-85). The post-operative mortality and morbidity rates were 8.2% and 61%, respectively. The 1-, 3- and 5-year overall survival rates were 85%, 64% and 53%, respectively. The median tumour size was 23 mm on pathology, ranging from 8 to 40. A tumour size >30 mm [odds ratio (OR) 2.471 (95% confidence interval (CI) 1.136-7.339), P = 0.001] and major post-operative complication [OR 3.369 (95% CI 1.038-10.938), P = 0.004] were independently associated with death <12 months in a multivariate analysis. CONCLUSION The present analysis of a series of 331 patients with hilar cholangiocarcinoma showed that tumour size >30 mm was independently associated with death <12 months.

Abstract
IMPORTANCE Ninety percent of cases of acute calculous cholecystitis are of mild (grade I) or moderate (grade II) severity. Although the preoperative and intraoperative antibiotic management of acute calculous cholecystitis has been standardized, few data exist on the utility of postoperative antibiotic treatment. OBJECTIVE To determine the effect of postoperative amoxicillin plus clavulanic acid on infection rates after cholecystectomy. DESIGN, SETTING, AND PATIENTS A total of 414 patients treated at 17 medical centers for grade I or II acute calculous cholecystitis and who received 2 g of amoxicillin plus clavulanic acid 3 times a day while in the hospital before and once at the time of surgery were randomized after surgery to an open-label, noninferiority, randomized clinical trial between May 2010 and August 2012. INTERVENTIONS After surgery, no antibiotics or continue with the preoperative antibiotic regimen 3 times daily for 5 days. MAIN OUTCOMES AND MEASURES The proportion of postoperative surgical site or distant infections recorded before or at the 4-week follow-up visit. RESULTS An imputed intention-to-treat analysis of 414 patients showed that the postoperative infection rates were 17% (35 of 207) in the nontreatment group and 15% (31 of 207) in the antibiotic group (absolute difference, 1.93%; 95% CI, -8.98% to 5.12%). In the per-protocol analysis, which involved 338 patients, the corresponding rates were both 13% (absolute difference, 0.3%; 95% CI, -5.0% to 6.3%). Based on a noninferiority margin of 11%, the lack of postoperative antibiotic treatment was not associated with worse outcomes than antibiotic treatment. Bile cultures showed that 60.9% were pathogen free. Both groups had similar Clavien complication severity outcomes: 195 patients (94.2%) in the nontreatment group had a score of 0 to I and 2 patients (0.97%) had a score of III to V, and 182 patients (87.8%) in the antibiotic group had a score of 0 to I and 4 patients (1.93%) had a score of III to V. CONCLUSIONS AND RELEVANCE Among patients with mild or moderate calculous cholecystitis who received preoperative and intraoperative antibiotics, lack of postoperative treatment with amoxicillin plus clavulanic acid did not result in a greater incidence of postoperative infections.

Abstract
OBJECTIVES To evaluate the influence of a biliary obstruction (BO) requiring biliary bypass on both short and long-term outcomes of patients undergoing Frey's procedure for chronic pancreatitis (CP). METHODS From 1999 to 2010, 33 consecutive patients underwent Frey's procedure for CP in two centers. Seventeen (54%) patients underwent biliary bypass to treat an associated BO. Characteristics and outcomes of these patients were compared to those of 16 others without BO. RESULTS Patients with BO had more severe disease including lower BMI and larger pancreatic head (4 cm vs. 6 cm, p = 0.021). The operative mortality was nil. Patients with BO experienced more overall postoperative complications (71% vs. 31%, p = 0.024) but similar major complication rates (18% vs. 6%, p = 0.316) compared to those without BO. After a median follow-up of 51 (1-96) months, 91% of the patients experienced either partial or complete relief of their symptoms and 36% exhibited deterioration of their endocrine function. Multivariate analysis revealed preoperative BO to be associated with long-term impairment of endocrine function (OR: 43.249; 95% CI 2.221-84.277; p = 0.013). CONCLUSION In patients undergoing Frey's procedure for CP, associated BO can be safely managed using biliary bypass. However, the severity of CP in these patients is responsible for a higher risk of long-term endocrine insufficiency.

Abstract
AIM Percutaneous drainage of abdominal and pelvic abscesses is a first-line alternative to surgery. Anterior and lateral approaches are limited by the presence of obstacles, such as the pelvic bones, bowel, bladder, and iliac vessels. The objective of this study was to assess the feasibility, safety, tolerability, and efficacy of a percutaneous, transgluteal approach by reviewing our clinical experience and the literature. MATERIALS AND METHODS We reviewed demographic, clinical and morphological data in the medical records of 30 patients having undergone percutaneous, computed tomography (CT)-guided, transgluteal drainage. In particular, we studied the duration of catheter drainage, the types of microorganisms in biological fluid cultures, complications related to procedures and the patient's short-term treatment outcome. RESULTS From January 2005 to October 2011, 345 patients underwent CT-guided percutaneous drainage of pelvis abscesses in our institution. A transgluteal approach was adopted in 30 cases (10 women and 20 men; mean age: 52.6 [range 14-88]). The fluid collections were related to post-operative complications in 26 patients (86.7 %) and inflammatory or infectious intra-abdominal disease in the remaining 4 patients (acute diverticulitis: n = 2; appendicitis: n = 1; Crohn's disease: n = 1) (13.3 %). The mean duration of drainage was 8.7 days (range 3-33). Laboratory cultures were positive in 27 patients (90 %) and Escherichia coli was the most frequently present microorganism (in 77.8 % of the positive samples). A transpiriformis approach (n = 5) was more frequently associated with immediate procedural pain (n = 3). No major complications were observed, either during or after the transgluteal procedure. Drainage was successful in 29 patients (96.7 %). One patient died from massive, acute cerebral stroke 14 days after drainage. CONCLUSION When an anterior approach is unfeasible, transgluteal, percutaneous, CT-guided drainage is a safe, well tolerated and effective procedure. Major complications are rare. This type of drainage is an alternative to surgery for the treatment of deep pelvic abscesses (especially for post-surgical collections).

Abstract
Since the initial studies published in the eighties, percutaneous radiologic drainage, is considered the first-line treatment of infected post-operative collections and is successful in over 80% of patients. Mortality due to undrained abscesses is estimated between 45 and 100%. Radiology-guided percutaneous drainage can be performed either with curative intent or to improve patient status prior to re-operation under better conditions. Cross-sectional imaging, using either ultrasound or computed tomography (CT), has changed the management of post-operative complications. Percutaneous drainage is most often performed by interventional radiologists and imaging is essential for road-mapping and guiding the puncture and drainage of intra-abdominal collections. Indeed, such imaging allows both identification of adjacent anatomical structures and determination of the best tract and the safest route. Cooperation between the surgeon and the interventional radiologist is essential to optimize the management and to avoid, if possible, surgery, which is so often difficult in this setting.

Abstract
We report a new variation of the left hepatic artery arising from the superior mesenteric artery. The variant was discovered during radiological examinations in a patient presenting with ruptured hepatocellular carcinoma of the left liver lobe. Anatomical description was based on CT-scan and angiographic analysis. When present the left hepatic artery originates from the left gastric artery, with an incidence of 12-34 %. Knowledge of left hepatic artery anatomy is mandatory to optimize surgical and radiological management in complex clinical situations.

Serum procalcitonin for predicting the failure of conservative management and the need for bowel resection in patients with small bowel obstruction. J Am Coll Surg 2013; 216:997-1004. [PMID: 23522439 DOI: 10.1016/j.jamcollsurg.2012.12.051] [Citation(s) in RCA: 39] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2012] [Revised: 12/15/2012] [Accepted: 12/17/2012] [Indexed: 12/16/2022]
Abstract
BACKGROUND Ischemia and necrosis are complications of small bowel obstruction (SBO) and require rapid surgical treatment. At present, there are no sufficiently accurate preoperative biomarkers of ischemia or necrosis. The objective of the current study was to evaluate the value of serum procalcitonin levels for predicting conservative management failure and the presence of intraoperatively observed bowel ischemia (reversible or not) in patients with SBO. STUDY DESIGN One hundred and sixty-six participants of 242 in a randomized controlled trial focusing on the management of SBO (Acute Bowel Obstruction Diagnostic study [ABOD], NCT00389116) had available data on procalcitonin and were included in the study. The primary study objective was to determine whether serum procalcitonin could identify patients in whom conservative management (CM) failed (the surgical management [SM] group) and the subset of SM patients with intraoperatively observed ischemia (reversible or not). For the analysis, the patients were divided into subgroups according to the success or failure of CM and (for surgically managed patients) the presence or absence of intraoperative ischemia (reversible or not). RESULTS Procalcitonin levels were higher in the SM group (n = 35) than in the CM group (n = 131) (0.53 vs 0.14 ng/mL; p = 0.031) and higher in the group managed surgically with ischemia (n = 12) than patients managed surgically without intraoperative ischemia (n = 23) (1.16 vs 0.21 ng/mL, respectively; p < 0.001). A multiple logistic regression showed that procalcitonin is a risk factor for CM failure (odds ratio = 3.5; 95% CI, 1.4-8.5; p = 0.006) and for ischemia (reversible or not) (odds ratio = 46.9; 95% CI, 4.0-547.3; p < 0.001). CONCLUSIONS Procalcitonin can help predict CM failure and occurrence of bowel ischemia (reversible or not) in SBO patients, but additional studies are needed.

Abstract
BACKGROUND Indications for preoperative biliary drainage (PBD) in the context of hepatectomy for hilar malignancies are still debated. The aim of this study was to investigate current European practice regarding biliary drainage before hepatectomy for Klatskin tumours. METHODS This was a retrospective analysis of all patients who underwent formal or extended right or left hepatectomy for hilar cholangiocarcinoma between 1997 and 2008 at 11 European teaching hospitals, and for whom details of serum bilirubin levels at admission and at the time of surgery were available. PBD was performed at the physicians' discretion. The primary outcome was 90-day mortality. Secondary outcomes were morbidity and cause of death. The association of PBD and of preoperative serum bilirubin levels with postoperative mortality was assessed by logistic regression, in the entire population as well as separately in the right- and left-sided hepatectomy groups, and was adjusted for confounding factors. RESULTS A total of 366 patients were enrolled; PBD was performed in 180 patients. The overall mortality rate was 10·7 per cent and was higher after right- than left-sided hepatectomy (14·7 versus 6·6 per cent; adjusted odds ratio (OR) 3·16, 95 per cent confidence interval 1·50 to 6·65; P = 0·001). PBD did not affect overall postoperative mortality, but was associated with a decreased mortality rate after right hepatectomy (adjusted OR 0·29, 0·11 to 0·77; P = 0·013) and an increased mortality rate after left hepatectomy (adjusted OR 4·06, 1·01 to 16·30; P = 0·035). A preoperative serum bilirubin level greater than 50 µmol/l was also associated with increased mortality, but only after right hepatectomy (adjusted OR 7·02, 1·73 to 28·52; P = 0·002). CONCLUSION PBD does not affect overall mortality in jaundiced patients with hilar cholangiocarcinoma, but there may be a difference between patients undergoing right-sided versus left-sided hepatectomy.

Abstract
BACKGROUND Incidental gallbladder cancer (GBC) is frequently discovered on the specimen when cholecystectomy for a benign disease is performed. The objective of the present study was to assess the management of incidental GBC patients in a French registry. METHODS Data on patients with GBC treated between 1998 and 2008 were retrospectively collated in a French, multicenter database. RESULTS The registry contained 218 patients with incidental GBC (67 men and 151 women; median age = 64 years; age range = 31-88). One hundred forty-eight (68%) patients underwent re-resection after a median time interval of 48 days (range = 2-245). The most common complete procedure (66% of cases) was 4b + 5 segmentectomy with lymphadenectomy but not bile duct resection. Port-site excision was performed in 54 patients. The mortality and morbidity rates were 3 and 37%, respectively. Resection of the common bile duct (43%) increased postoperative complications (60 vs. 23%, p = 0.0001). Local residual tumor was found in 83 (56%) patients; it was significantly correlated with the T stage and influenced long-term survival. R0 was obtained in 143 (97%) patients and port-site invasion was histologically confirmed in one patient (1.8%). After a median follow-up period of 34 months, the 1-, 3-, and 5-year survival rates for the 148 patients with re-resection were 76, 54, and 41%, respectively. Re-resection significantly increased survival in patients with T2 (p = 0.0001) and T3 (p = 0.04) disease. Resection of the common bile duct increased neither R0 resection nor overall survival (p = 0.06). CONCLUSION This study validates the concept of re-resection in T2 and T3 GBC. Bile duct resection increases postoperative morbidity but does not improve survival. There is currently a modification in the surgical management of incidental GBC, with minor liver resection and no common bile duct resection.

Abstract
INTRODUCTION Jaundice is frequent in patients with gallbladder cancer (GBC) and indicates advanced disease and, according to some teams, precludes routine operative exploration. The present study was designed to re-assess the prognostic value of jaundice in patients with GBC. METHODS Patients with GBC operated from 1998 to 2008 were included in a retrospective multicenter study (AFC). The main outcome measured was the prognostic value of jaundice in patients with GBC focusing on morbidity, mortality and survival. RESULTS A total of 110 of 429 patients with GBC presented with jaundice, with a median age of 66 years (range: 31-88). The resectability rate was 45% (n=50) and the postoperative mortality and morbidity rates were 16% and 62%, respectively; 71% had R0 resection and 46% had lymph node involvement. Overall 1- and 3-year survivals of the 110 jaundiced patients were 41% and 15%, respectively. For the 50 resected patients, 1- and 3-year survivals were 48% and 19%, respectively (real 5-year survivors n=4) which were significantly higher than that of the 60 non-resected patients (31%, 0%, p=0.001). Among the resected jaundiced patients, T-stage, N and M status were found to have a significant impact on survival. R0 resection did not increase the overall survival in all resected patients, but R0 increased median survival in the subgroup of N0 patients (20 months versus 6 months, p=0.01). CONCLUSION This series confirms that jaundice is a poor prognostic factor. However, the presence of jaundice does not preclude resection, especially in highly selected patients (N0).

Abstract
INTRODUCTION Surgical resection is the only option for long-term survival in patients with hilar cholangiocarcinoma (HC), but it is associated with high morbidity and mortality. The aim of the present study was to prospectively assess the perioperative management and short-term outcomes of surgical treatment of HC in a recent, multi-institutional study with a short inclusion period. METHODS Between January and December 2008, a register prospectively collected data on patients operated on for HC (exploratory or curative surgery) in eight tertiary centers. The register focused on perioperative management, resectability, surgical procedures employed, morbidity, and mortality. The study cohort consisted of 56 patients (40 men and 16 women) with a median age of 63 years (range, 33-83 years). RESULTS Among the 56 patients, 47 (84%) were jaundiced and 42 (75%) tumors were classified as Bismuth-Corlette type III-IV. Nine patients (16%) underwent staging laparoscopy and four (7%) received neoadjuvant chemotherapy. Preoperative biliary drainage (endoscopy, 42%) was performed in 38 (81%) jaundiced patients and portal vein embolization (right side, 83%) was performed prior to surgery in 18 patients (32%). Among these 56 patients, curative resection was achieved in 39 (70%). All underwent major liver resection (>3 segments), bile duct resection, and lymphadenectomy. Thirteen patients (36%) underwent portal vein resection, one of whom also required pancreaticoduodenectomy. Eighty-two percent of resected patients (n = 32) had no proof of malignancy prior to hepatectomy. Clear surgical margins were obtained in 77% (n = 30). The postoperative mortality was 8% and complications occurred in 72% of the resected patients. Seven (25%) patients required reoperation, and 15 (54%) patients required percutaneous drainage. In a univariate analysis, the risk factors for morbidity were intraoperative blood transfusion (p = 0.009) and vascular clamping (p = 0.006). The median length of hospitalization was 20 ± 13 days. CONCLUSION Curative resection for HC is associated with a high rate of R0 resection. However, surgery is associated with high levels of morbidity and mortality, despite intensive perioperative management.

AJCC 7th edition of TNM staging accurately discriminates outcomes of patients with resectable intrahepatic cholangiocarcinoma: By the AFC-IHCC-2009 study group. Cancer 2010; 117:2170-7. [PMID: 21523730 DOI: 10.1002/cncr.25712] [Citation(s) in RCA: 144] [Impact Index Per Article: 10.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2010] [Revised: 08/26/2010] [Accepted: 09/13/2010] [Indexed: 12/15/2022]
Abstract
BACKGROUND This year, the 7th edition of the AJCC staging manual has for the first time attributed a unique pTNM staging to intrahepatic cholangiocarcinoma (IHCC) that is intended to replace the 2 Western and ideally also the 2 Eastern systems currently in use. This proposal, which has not yet been validated, was tested in the current study. METHODS Among 522 patients operated on with curative intent for an IHCC between 1994 and 2008 in tertiary hepatobiliary centers, those with mass-forming-type IHCCs, an R0 resection, and accurate pathological node staging were retained for evaluation. The distribution of these patients and their actuarial survival in the new TNM stages (as well as in the 4 previous ones) were compared. RESULTS Only 163 patients fulfilled the inclusion criteria, mainly because of the lack of routine lymphadenectomy, but patients and tumors characteristics of this population were representative. These patients were evenly distributed between AJCC 7th edition stages (stage I, 28%; stage II, 32%; stage III, 35%), which was not the case for the other systems. With an average follow-up of 34 months in survivors, the AJCC 7th edition was more discriminating than the others in predicting survival (median for stage I not reached; for stage II, 53 months, P = .01; for stage III, 16 months, P < .0001). Survival of these patients according to the 2 Japanese classifications was identical to that anticipated. CONCLUSIONS The 7th edition is clinically relevant and may be applicable worldwide, provided routine lymphadenectomy at the time of surgery for IHCC becomes the standard of care.
