BACKGROUND Approximately one-fifth of patients with colorectal cancer present with hepatic metastases. There are limited prospective data on the outcomes of synchronous combined liver and bowel surgery and liver-first or bowel-first routes where contemporary chemo(radio)therapy is integrated into management. METHODS Between 1 April 2014 and 31 March 2017, 125 patients with colorectal cancer and synchronous liver metastases were recruited. Data are reported on pathway-specific outcomes, including perioperative complications, treatment completion, and overall and disease-free survival. The study was registered with ClinicalTrials.gov (NCT02456285). RESULTS There was no difference in age, body mass index, or Charlson score between surgical groups. Neoadjuvant chemotherapy was used in 50 (40%) patients for a mean duration of 4.6 months (standard deviation [SD] 5.4), and mean time from completion of chemotherapy to surgery was 2.6 months (SD 1.9). Complications were similar between patients completing the synchronous and staged pathways (p = 0.66). Mean total inpatient stay was 16.5 days (SD 8.1) for staged surgery compared with 16.8 days (SD 10.3) for the synchronous group (t-test; p = 0.91). There was no difference in time to treatment completion between pathways. Thirty six (35%) patients were disease-free at 12 months, with no significant difference between groups (Chi-square, p = 0.448). Quality of life was similar in all surgical groups. CONCLUSIONS Perioperative complications and oncological and healthcare occupancy outcomes are equivalent between patients completing staged and synchronous pathways for the management of patients with colorectal cancer and synchronous liver metastases. Future studies should focus on optimizing the criteria for pathway selection, incorporation of cancer genomics data, and patient (user) preferences.

Background: This study reports the outcome of a work-up programme for resection of peri-hilar cholangiocarcinoma (PH-CCA) without the use of staging laparoscopy. Methods: This is a clinical case cohort series of patients undergoing surgical resection of PH-CCA without the use of staging laparoscopy in the work-up algorithm. During the 13 years from 1 January 2009 to 1 January 2022, 32 patients underwent laparotomy for planned surgical resection of PH-CCA. Data were collected on demographic profile, admission biochemistry, radiology, pre-operative intervention, operation and outcome, together with post-operative complications and disease-free and overall survival. Results: All patients underwent pre-operative contrast-enhanced CT. Twenty-four (75%) underwent pre-operative MR. Twenty-three (72%) underwent pre-operative biliary drainage. Twenty-nine patients (91%) had either type III or IV peri-hilar cholangiocarcinoma. One patient (3%) in this series underwent a non-resectional laparotomy. Twenty-nine (91%) had a final histopathological diagnosis of PH-CCA. One further patient had a final diagnosis of an intraductal papillary neoplasm of the biliary tree (IPNB) with high-grade dysplasia but no invasive cancer. Eleven patients (36%) received chemotherapy after surgery. The median (95% CI) time to recurrence was 14 (7–31) months. The median survival was 25 (18-upper limit not reached) months. Conclusion: This cohort of 32 patients undergoing attempted resection for PH-CCA without the use of staging laparoscopy in the work-up algorithm indicates that with careful attention to patient fitness and cross-sectional and interventional radiologic/endoscopic imaging, a very low non-therapeutic laparotomy rate of 3% can be achieved and sustained.

Background Pancreatic cancer is currently the fourth most common cause of cancer-related mortality in the economically developed world and is set to become the second most common cause of cancer-related mortality within the next few years. NICE guidance makes a strong recommendation to offer up-front surgery to people with resectable pancreatic cancer, without preoperative biliary drainage, if sufficiently fit for surgery. The aim of this study was to perform a propensity-matched comparison of patients with pancreatic cancer undergoing surgery, with and without biliary stenting, to examine perioperative outcomes and to perform an intention to treat analysis to evaluate long-term survival between the two groups. Methods This was an observational study of a cohort of consecutive patients presenting with obstructive jaundice and undergoing pancreatoduodenectomy for pancreatic and periampullary malignancies between November 2015 and May 2019. Data related to patient and tumour characteristics, biliary drainage, surgery and histopathology were gathered and analysed from a prospectively maintained electronic database. Post-operative complications were defined and graded according to the definitions of the International Study Group on Pancreatic Surgery (ISGPS) and the Clavien-Dindo system. Data related to adjuvant treatment, disease recurrence and overall survival were also analysed. Results In this retrospective study of 216 consecutive operable patients, 70 followed the fast-track (FT) pathway and 146 had pre-operative biliary drainage (PBD). All 70 patients in the fast-track group and 122 out of 146 in the PBD group proceeded to surgery (100% and 83.6% respectively, p = 0.001). Interval time from diagnostic CT scan to surgery and from MDT decision to treat to surgery was much shorter in the FT group (median range) 8 vs 43 days p Conclusions These data strengthen the existing evidence that, for a person with pancreatic cancer who is proceeding to surgery, the best approach is to avoid pre-operative biliary drainage. The optimal comparison to the neoadjuvant approach is upfront fast-track surgery without biliary drainage followed by adjuvant therapy.

Postoperative outcomes including complications, readmission and mortality rates were comparable in the two groups. There was no difference in survival.For a person with pancreatic cancer who is proceeding to surgery, the best approach is to avoid pre-operative biliary drainage.

Background A shift towards parenchymal-sparing liver resections in open and laparoscopic surgery emerged in the last few years. Laparoscopic liver resection is technically feasible and safe, and consensus guidelines acknowledge the laparoscopic approach in the posterosuperior segments. Lesions situated in these segments are considered the most challenging for the laparoscopic approach. The aim of this trial is to compare the postoperative time to functional recovery, complications, oncological safety, quality of life, survival and costs after laparoscopic versus open parenchymal-sparing liver resections in the posterosuperior liver segments within an enhanced recovery setting. Methods The ORANGE Segments trial is an international multicentre randomised controlled superiority trial conducted in centres experienced in laparoscopic liver resection. Eligible patients for minor resections in the posterosuperior segments will be randomised in a 1:1 ratio to undergo laparoscopic or open resections in an enhanced recovery setting. Patients and ward personnel are blinded to the treatment allocation until postoperative day 4 using a large abdominal dressing. The primary endpoint is time to functional recovery. Secondary endpoints include intraoperative outcomes, length of stay, resection margin, postoperative complications, 90-day mortality, time to adjuvant chemotherapy initiation, quality of life and overall survival. Laparoscopic liver surgery of the posterosuperior segments is hypothesised to reduce time to functional recovery by 2 days in comparison with open surgery. With a power of 80% and alpha of 0.04 to adjust for interim analysis halfway the trial, a total of 250 patients are required to be randomised. Discussion The ORANGE Segments trial is the first multicentre international randomised controlled study to compare short- and long-term surgical and oncological outcomes of laparoscopic and open resections in the posterosuperior segments within an enhanced recovery programme.

Objective The aim of the study was to determine the impact of age on curative management and outcomes of patients with pancreatic ductal adenocarcinoma. Methods Patients who underwent resection for pancreatic ductal adenocarcinoma at 2 units were retrospectively reviewed (between 2005 and 2017) and stratified by age (older patients ≥70 years). Regression analysis was used to explore factors impacting administration of adjuvant chemotherapy and survival. The Kaplan-Meier method was used to estimate overall survival (time from surgery to death). Statistical significance was set at P < 0.05. Results From 2005 to 2014, 222 patients were identified ( 0.05). Frailty was the commonest reason (36.8%) to decline chemotherapy in elderly patients. In patients receiving adjuvant chemotherapy, completion rates (P = 0.32) and overall survival (24 months vs 30 months, P = 0.50) were no different. Conclusions Elderly patients demonstrate similar outcomes to younger yet are less likely to commence chemotherapy because of frailty. Holistic preoperative assessment may improve selection for curative treatment.

The aim of the study was to evaluate any social, occupational and physical factors, which may influence the occurence or cause of a primary inguinal hernia in two European countries. A questionnaire was completed by all the respondents in the setting of an out-patient clinic prospectively at the time of initial presentation and the data were collected on a secure database. All responses for each question were explored via appropriate descriptive statistics. Statistical comparisons were made using Fisher’s exact test where appropriate. 537 adults completed the questionnaire and had their data analysed. Comparisons between those that presented with a primary complaint of either ‘bulge/swelling’ or ‘discomfort/pain’ found no differences in occupation, age or any other demographic data. Equal proportions of patients who described a single strenuous event presented with a bulge/swelling or discomfort/pain. The reporting of a causative single strenuous event was not significantly influenced by occupation, lifestyle or amount of activity carried out nor was there any significant influence upon when a hernia presented after the suspected strenuous event, although the majority reported a lump within 1 week. This study cannot at present support the belief that a single strenuous event will be the sole cause for the development of a primary inguinal hernia.

Introduction: Evolution in laparoscopic liver surgery during the past two decades is an indisputable fact. According to the second international consensus conference for laparoscopic liver resection held in Morioka, Japan in 2014 major resections are still regarded as innovative procedures in the exploration phase. On this basis, our study aims to explore the efficacy and safety of laparoscopic vs. open major liver resection and therefore increase the existing evidence on major laparoscopic liver surgery.Methods: All consecutive patients who underwent major liver resection, open and laparoscopic from January 2016 to May 2018 were identified from our prospectively maintained database. Propensity score matching analysis was performed using R statistical tool in SPSS to isolate matched open and laparoscopic cases which were compared for intraoperative and postoperative short-term outcomes. Lotus ultrasonic energy device was used for parenchymal transection in laparoscopic cases vs. CUSA in open procedures.Results: Propensity score matching analysis was performed on 82 consecutive patients (61 open and 21 laparoscopic major hepatectomies) resulting in 40 matched patients, 20 in each group. The mean total duration of surgery and duration of parenchymal transection were slightly longer in the laparoscopic group (p = 0.419, p = 0.348). There was no difference in the intraoperative and postoperative transfusion rates. Patients after laparoscopic surgery were discharged 2 days earlier on average (p = 0.310). No difference was observed in complication rates and mortality.Conclusion: Our data did not reveal inferiority of the laparoscopic major hepatectomy vs. the open approach in any parameter compared. The use of the Lotus ultrasonic energy device appeared to be efficient and safe for parenchymal transection in the laparoscopic procedures.

BackgroundSportsman's hernia/athletic pubalgia is a recognized cause of chronic groin pain in athletes. Both open and laparoscopic surgical repairs have been described for treatment, but there are no comparative studies. The hypothesis here was that relief of pain would be achieved earlier in patients treated with open minimal suture repair than totally extraperitoneal repair.MethodsA randomized multicentre trial in four European countries was conducted to compare open minimal suture repair with totally extraperitoneal repair. The primary endpoint was complete relief of pain (visual analogue scale (VAS) score 20 or less on a scale from 0 to 100 mm) at 1 month. Secondary endpoints included complications, time to return to sporting activity, and number of patients returning to sport within 1 year.ResultsA total of 65 athletes (92 per cent men) with a median age of 29 years were enrolled (31 open repair, 34 totally extraperitoneal repair). By 4 weeks after surgery, median preoperative VAS scores had dropped from 70–80 to 10–20 in both groups (P < 0·001). Relief of pain (VAS score 20 or less) during sports activity 4 weeks after surgery was achieved in 14 of 31 patients after open repair and 24 of 34 after totally extraperitoneal repair (P = 0·047). Return to full sporting activity was achieved by 16 and 18 patients respectively after 1 month (P = 0·992), and by 25 versus 31 after 3 months (P = 0·408).ConclusionTotally extraperitoneal repair was less painful than open repair in the first month, but otherwise both procedures were similarly effective in treating chronic pain due to sportsman's hernia.

Minimally invasive incisional hernia repair has been established as a safe and efficient surgical option in most centres worldwide. Laparoscopic technique includes the placement of an intraperitoneal onlay mesh with fixation achieved using spiral tacks or sutures. An additional step is the closure of the fascial defect depending upon its size. Key outcomes in the evaluation of ventral abdominal hernia surgery include postoperative pain, the presence of infection, seroma formation and hernia recurrence. TACKoMESH is a randomised controlled trial that will provide important information on the laparoscopic repair of an incisional hernia; 1) with fascial closure, 2) with an IPOM mesh and 3) comparing the use of an articulating mesh-fixation device that deploys absorbable tacks with a straight-arm mesh-fixation device that deploys non-absorbable tacks. A prospective, single-centre, double-blinded randomised trial, TACKoMESH, will establish whether the use of absorbable compared to non-absorbable tacks in adult patients undergoing elective incisional hernia repair produces a lower rate of pain both immediately and long-term. Eligible and consenting patients will be randomized to surgery with one of two tack-fixation devices and followed up for a minimum one year. Secondary outcomes to be explored include wound infection, seroma formation, hernia recurrence, length of postoperative hospital stay, reoperation rate, operation time, health related quality of life and time to return to normal daily activity. With ongoing debate around the best management of incisional hernia, continued trials that will add substance are both necessary and important. Laparoscopic techniques have become established in reducing hospital stay and rates of infection and report improvement in some patient centered outcomes whilst achieving similarly low rates of recurrence as open surgical techniques. The laparoscopic method with tack fixation has developed a reputation for its tendency to cause post-operative pain. Novel additions to technique, such as intraoperative-sutured closure of a fascial defect, and developments in surgical technology, such as the evolution of composite mesh design and mesh-fixation devices, have brought about new considerations for patient and surgeon. This study will evaluate the efficacy of several new technical considerations in the setting of elective laparoscopic incisional hernia repair.

Objective Patients with severe acute pancreatitis were excluded from major trials of human recombinant activated protein C (Xigris) because of concern about pancreatic haemorrhage although these individuals have an intense systemic inflammatory response that may benefit from treatment. The object of this study was to provide initial safety data evaluating Xigris in severe acute pancreatitis. Design Prospective clinical trial recruiting between November 2009 and October 2011. Patients received human recombinant activated protein C (Xigris) for 24 h by intravenous infusion (24 μg/kg/h) in addition to standard clinical care. A matched historical control group treated within the same hospital unit were used to compare outcomes. Of 166 consecutive admitted patients, 43 met the screening criteria for severe acute pancreatitis and 19 were recruited, all contributing to the analyses. Results Compared to historical controls, there were fewer bleeding events in the Xigris group although the finding did not reach significance (Xigris 0% vs. Control 21%, p = 0.13), similarly further intervention appeared less frequent (11% vs. 47%, p = 0.07) in the treatment group. Length of stay was shorter for patients receiving Xigris (19 vs. 41 days, p = 0.03) as was inotrope use (5% vs. 32%, p = 0.02); mortality and incidence of infections in both groups were similar. Biomarker protein C increased while IL-6 decreased following infusion. Conclusions A 24-hr infusion of Xigris appears safe when used in patients with severe acute pancreatitis.

Objectives Nutritional deficiencies and immune dysfunction in cancer patients may contribute to postoperative septic morbidity. This trial compared the effects of perioperative enteral immunonutrition (EIN) versus standard enteral nutrition (SEN) on systemic and mucosal immunity in patients undergoing pancreaticoduodenectomy for periampullary cancer. Methods Thirty-seven patients were randomized (EIN, n = 17; SEN, n = 20) to receive feed for 14 days preoperatively and 7 days postoperatively. Mediators of systemic immunity (interleukin 1α, tumor necrosis factor α, lymphocytes subsets, and complement components) and of mucosal immunity in duodenal biopsies, nutritional markers and parameters were evaluated. Results The groups were comparable for demographics, the concentrations of mediators of systemic and mucosal immunity at time of recruitment, and for the duration and amount of feed received. Preoperative EIN rather than SEN was associated with significant reductions in plasma tumor necrosis factor α and total hemolytic complement. Enteral immunonutrition-fed patients had significantly higher total lymphocyte count on the third postoperative day and significantly greater rise in CD4/CD8 ratio from day 3 to day 7 postoperatively compared with SEN-fed patients. Conclusions The perioperative administration of EIN rather than SEN is associated with a favorable modulation of the inflammatory response and enhancement of systemic immunity in patients undergoing pancreaticoduodenectomy for periampullary cancer.

Aims: To ascertain any predictors of potential food poisoning pathogens and development of post-infective irritable bowel syndrome (IBS) in UK travellers. An analysis was undertaken on prospectively collected data on 527 patients reporting symptoms of suspected food poisoning between June 2012 and June 2015. Main outcome measures: Positive stool sample indicative of food poisoning pathogens and diagnosis of post-infective IBS. Results: Data on 527 patients were examined. The large majority of patients did not provide a stool sample on return from holiday ( n = 430, 81.6%) as few visited a Doctor locally or in the UK. Only 18 patients (18.6%, 95% confidence interval [CI] 11.4–27.7) who provided a stool sample were positive for microbiological food poisoning pathogens. Univariate analysis indicated a significant relationship between a positive stool sample and whether the individual sought any medical assistance at the resort (odds ratio [OR] 0.24, 95% CI 0.08–0.70) and whether they took any treatment (including self-medicated), (OR 0.21, 95% CI 0.06–0.67). Of the 527 patients only 30 (5.7%, 95% CI 3.9–8.1) experienced post-infective IBS. Univariate regression indicated a significant relationship between experiencing Per Rectal (PR) bleeding and a diagnosis of post-infective IBS (OR 3.64, 95% CI 1.00–10.49). Univariate regression also indicated an increase in the risk of developing post-infective IBS with increasing duration of symptoms (OR 1.04, 95% CI 1.02–1.05). No significant relationship was found between a positive stool sample and developing post-infective IBS ( P = 0.307). Conclusions: Very few patients provide a stool sample after experiencing holiday sickness abroad. Of those that do, only a small proportion have a positive stool sample indicative of a food poisoning microorganism. Around 6% of individuals were diagnosed with post-infective IBS. Those individuals with PR bleeding and symptoms persisting for longer durations were significantly more at risk of developing post-infective IBS, whilst medical aid and treatment abroad was found to reduce the odds of a positive stool sample.

Objectives. This study is a questionnaire survey on the use of pharmacological agents to modify liver ischaemia-reperfusion (IR) injury in patients undergoing hepatectomy for colorectal liver metastases with the target population being those units participating in the LiverMetSurvey international registry. Methods. Members of LiverMetSurvey were sent an online questionnaire using SurveyMonkey comprising ten questions on the use of pharmacological agents to modulate hepatic IR injury in the perioperative period after hepatectomy. The questionnaire was sent to 446 clinicians registered with the LiverMetSurvey. There were 83 (19%) respondents. Results. Fifty-two (77% of 68 respondents to this question) never used pharmacological agents to modify liver IR injury during hepatectomy. Thirteen (19%) used pharmacological agents selectively. Three (4%) used these routinely. N-Acetylcysteine was the most widely used pharmacological agent with equal distribution of use around intraoperative and postoperative periods. Conclusions. This is believed to be the first survey on the use of pharmacological agents to modify liver IR injury. The target population is clinicians involved in liver resection. The results show that pharmacological modulation is used by only a minority of respondents to this questionnaire and that when this treatment is selected, N-acetylcysteine is the most frequently used.

Background The aim of this study was to conduct a comprehensive systematic review comparing tissue glue (TG) against tacks/staples for mesh fixation in laparoscopic (totally extra-peritoneal and trans-abdominal pre-peritoneal) groin hernia repair with the incidence of post-operative chronic pain as the primary outcome measure.

Pancreaticoduodenectomy is the standard of care for tumors confined to the head of pancreas and can be undertaken with low operative mortality. The procedure has a high morbidity, particularly in older patient populations with preexisting comorbidities. This study evaluated the role of cardiopulmonary exercise testing to predict postoperative morbidity and outcome in high-risk patients undergoing pancreaticoduodenectomy. In a prospective cohort of consecutive patients undergoing pancreaticoduodenectomy, those aged over 65 years (or younger with comorbidity) were categorized as high risk and underwent preoperative assessment by cardiopulmonary exercise testing (CPET) according to a predefined protocol. Data were collected on functional status, postoperative complications, and survival. A total of 143 patients underwent preoperative assessment, 50 of whom were deemed to be at low risk for surgery per study protocol. Of 93 high-risk patients, 64 proceeded to surgery after preoperative CPET. Neither anaerobic threshold (AT) nor maximal oxygen consumption ( $$ \dot{V} $$ o 2 MAX) predicted patient mortality or morbidity. However, ventilatory equivalent of carbon dioxide ( $$ \dot{V} $$ e/ $$ \dot{V} $$ co 2) at AT was a predictive marker of postoperative mortality, with an area under the curve (AUC) of 0.84 (95 % confidence interval [CI] 0.63–1.00, p = 0.020); a threshold of 41 was 75 % sensitive and 95 % specific (positive predictive value 50 %, negative predictive value 98 %). Above this threshold, raised $$ \dot{V} $$ e/ $$ \dot{V} $$ co 2 predicted poor long-term survival (hazard ratio 2.05, 95 % CI 1.09–3.86, p = 0.026). CPET is a useful adjunctive test for predicting postoperative outcome in patients being assessed for pancreaticoduodenectomy. Raised CPET-derived $$ \dot{V} $$ e/ $$ \dot{V} $$ co 2 predicts early postoperative death and poor long-term survival.

Background Current guidelines recommend pharmacological prophylaxis for patients undergoing abdominal surgery for malignancy. Liver resection exposes patients to risk factors for venous thromboembolism, but there is a risk of bleeding. The aim of this study is to evaluate the evidence base supporting the use of pharmacological thromboprophylaxis in liver surgery. Methods An electronic search was carried out for studies reporting the incidence of VTE following liver resection comparing patients receiving pharmacological prophylaxis with those who did not. The search resulted in 990 unique citations. Following the application of strict eligibility criteria 5 studies comprise the final study population. Results Included studies report on 3675 patients undergoing liver resection between 1999 and 2013. 2256 patients received chemical thromboprophylaxis, 1412 had mechanical prophylaxis only and 7 received no prophylaxis. Meta-analysis revealed lower VTE rates in patients receiving chemical thromboprophylaxis (2.6%) compared to without prophylaxis (4.6%) (Dichotomous correlation test, odds ratio: 0.631 [95% Cl: 0.416–0.959], Fixed model, p = 0.030). Data regarding bleeding could not be pooled for meta-analysis, but chemical thromboprophylaxis was reported as safe in four studies. Conclusion This systematic review and meta-analysis of retrospective studies indicates that the use of perioperative chemical thromboprophylaxis reduces VTE incidence following liver surgery without an apparent increased risk of bleeding.

To examine clinical outcome in a consecutive cohort of patients undergoing open necrosectomy for postinflammatory necrosis.The last decade has witnessed major developments in the surgical management of pancreatic necrosis. Minimally invasive approaches have become established. However, there are limited data from contemporary open necrosectomy, in particular where multidisciplinary care and aggressive interventional radiology are used. This report provides data on outcome from open necrosectomy in a tertiary referral Hepatobiliary unit over the last decade.During the period January 1, 2000 to July 31, 2008, 1535 patients were admitted with a final discharge code of acute pancreatitis. Twenty-eight (1.8%) of all admissions underwent open surgical necrosectomy. Twenty-four (86%) were tertiary referral patients.The median APACHE II score on admission was 10.5 (5-26). Median logistic organ dysfunction score on admission was 3 (0-10). Median LODS score after surgery was 2 (0-8). Twenty patients (71%) underwent radiologically guided drainage of collections before surgery. Thirty-day mortality occurred in 2 (7%), 4 further deaths occurred in patients after discharge from intensive care resulting in a total of 6 (22%) episode-related deaths.Modern open necrosectomy can be performed without the procedure-related deterioration in organ dysfunction associated with major debridement. Multidisciplinary care with an emphasis on aggressive radiologic intervention before and after surgery results in acceptable outcomes in this cohort of critically ill patients. Newer laparoscopic techniques must demonstrate similar outcomes in the setting of stage-matched severity before wider acceptance.

Objectives No single aetiological factor has been proven to cause long-standing groin pain in athletes and no sole operative technique (either open or laparoscopic) has been shown to be the preferred method of repair. The aim of this systematic review was to determine whether there are any differences in the return to full sporting activity following laparoscopic repair of groin pain in athletes. Data sources The minimal access approaches include laparoscopic transabdominal pre-peritoneal (TAPP) or endoscopic total extraperitoneal (TEP) techniques. A systematic literature search was performed in PubMed, SCOPUS, UpToDate and the Cochrane Library databases. Series reporting laparoscopic repair (TAPP/TEP) of groin pain in adult (>18 years) athletes were included. The primary outcome was return to full sporting activity and secondary outcomes included percentage success rates and complications of operations. Results Only 18 studies fulfilled the search criteria with both laparoscopic and sports hernia repairs. The studies were mainly observational with some reporting comparative data, but no large randomised controlled trials were detected. The median return to sporting activity of 4 weeks (28 days) was the same for the TAPP as well as TEP techniques. No real difference in secondary outcome measures was shown. More reported cases to date in the literature used the TAPP technique compared with TEP repair (n=605 vs n=266). Conclusions Laparoscopic surgery for elite athlete groin pain is increasingly becoming more common with almost 1000 patients reported since 1997. No particular laparoscopic technique appears to offer any advantage over the other.

Purpose: Some data have suggested that major surgery is associated with the post-operative growth of residual tumour masses but the mechanism of this is unknown. This study was designed to determine the relationship between intraperitoneal (IP) cytokine levels, and laparotomy in benign and malignant settings. Methods: Intraperitoneal fluid specimens were obtained at the start and at the end of laparotomy in patients with benign conditions (n=10) and in others undergoing resection of hepatic metastases from colorectal cancer (n=10). Using ELISA the concentration of the angiogenic cytokines, HGF, VEGF-A, VEGF-C, VEGF-D and FGF-2 was determined. Results: The data show that in 16 of 20 patients there was a significant increase (P=0.006) in the IP concentration of hepatocyte growth factor (HGF) but not in the other growth factors by the end of the operation. The mean increase in HGF concentration was 821.5 pg/ml (95% CI: 11.0–6,426.0). Neither the groups (malignant and non-malignant) nor the length of operation correlated with greater or lesser increases in HGF. Conclusion: The observation that the increase in HGF occurred in both the cancer and non-cancer groups suggests that it is the surgery rather than the disease that is associated with the increased cytokine concentration. As HGF is a potent endothelial, epithelial and mesenchymal mitogen the data highlight HGF as a potential target for anti-cancer treatments in the peri-operative period. However, investigators should closely monitor wound healing as this may be compromised by this new class of drugs.
