Background: Surgical site infections (SSI) are one of the most common hospital acquired infections and result in increased morbidity, mortality and financial burden on health services. The incidence of SSIs are not clearly defined and infection rates as varied as 20%–40% have been reported. The aim of this study was to systematically review the incidence and risk factors of SSI following HPB surgery. Methods: The database of Medline (via PubMed) was systematically searched from 2013–2022. Articles were screened using the PRISMA statement and those that met the inclusion criteria were included in the study. Results: Sixteen studies were eligible for inclusion in this systematic review. The average incidence of SSI was 29.8%. Key risk factors identified included male gender, open surgery, preoperative biliary stenting and obesity. Conclusions: The incidence of SSI following HPB surgery varied, but it is generally high. A variety of pre-disposing patient factors can affect infection rates following HPB surgery. The results from this study suggest that perhaps laparoscopic surgery should be used where possible, and that there should be an awareness that gender, obesity and the use of stents may increase the incidence of SSIs following these operations.

Abstract 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. Trial registration ClinicalTrials.gov NCT03270917 . Registered on September 1, 2017. Before start of inclusion. Protocol version: version 12, May 9, 2017

Acute pancreatitis ,Antibiotics ,Procalcitonin ,Medicine (General) ,R5-920 - Abstract
Abstract Background Differentiating infection from inflammation in acute pancreatitis is difficult, leading to overuse of antibiotics. Procalcitonin (PCT) measurement is a means of distinguishing infection from inflammation as levels rise rapidly in response to a pro-inflammatory stimulus of bacterial origin and normally fall after successful treatment. Algorithms based on PCT measurement can differentiate bacterial sepsis from a systemic inflammatory response. The PROCalcitonin-based algorithm for antibiotic use in Acute Pancreatitis (PROCAP) trial tests the hypothesis that a PCT-based algorithm to guide initiation, continuation and discontinuation of antibiotics will lead to reduced antibiotic use in patients with acute pancreatitis and without an adverse effect on outcome. Methods This is a single-centre, randomised, controlled, single-blind, two-arm pragmatic clinical and cost-effectiveness trial. Patients with a clinical diagnosis of acute pancreatitis will be allocated on a 1:1 basis to intervention or standard care. Intervention will involve the use of a PCT-based algorithm to guide antibiotic use. The primary outcome measure will be the binary outcome of antibiotic use during index admission. Secondary outcome measures include: safety non-inferiority endpoint all-cause mortality; days of antibiotic use; clinical infections; new isolates of multiresistant bacteria; duration of inpatient stay; episode-related mortality and cause; quality of life (EuroQol EQ-5D); and cost analysis. A 20% absolute change in antibiotic use would be a clinically important difference. A study with 80% power and 5% significance (two-sided) would require 97 patients in each arm (194 patients in total): the study will aim to recruit 200 patients. Analysis will follow intention-to-treat principles. Discussion When complete, PROCAP will be the largest randomised trial of the use of a PCT algorithm to guide initiation, continuation and cessation of antibiotics in acute pancreatitis. PROCAP is the only randomised trial to date to compare standard care of acute pancreatitis as defined by the International Association of Pancreatology/American Pancreatic Association guidelines to patients having standard care but with all antibiotic prescribing decisions based on PCT measurement.

Background: Index admission laparoscopic cholecystectomy is the standard of care for patients admitted to hospital with symptomatic acute cholecystitis. The same standard applies to patients suffering with mild acute biliary pancreatitis. Operating theatre capacity can be a significant constraint to same admission surgery. This study assesses the impact of dedicated theatre capacity provided by a specialist surgical team on rates of index admission cholecystectomy.Methods: This clinical cohort study compares the management of patients with symptomatic gallstone disease admitted to a tertiary care university teaching hospital over two equal but chronologically separate time periods. The periods were before and after service reconfiguration including a specialist HPB service with dedicated operating theatre time allocation.Results: There was a significant difference in the number of admissions over the two time periods with a greater proportion of patients having index admission surgery in the second time period with correspondingly fewer having more than one admission during this latter time period. In the second time period 43% of patients underwent index admission cholecystectomy compared to 23% in the first (P < 0.001). The duration of surgery was shorter for patients undergoing surgery during the second time period [135 (102–178) min in the first period and in the second period 106 (89–145) min] (P = 0.02).Discussion: This paper shows that the concentration of theatre resources and surgical expertise into regular theatre access for patients undergoing urgent laparoscopic cholecystectomy is an effective and safe model for dealing with acute biliary disease.

Abstract Background 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. Methods 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. Discussion 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.

Hepatectomy together with systemic chemotherapy is the treatment of choice for patients with liver-limited colorectal metastases. Although the open approach to hepatectomy remains a standard option, there is increasing recognition of the potential advantages of laparoscopic hepatectomy. Laparoscopic approaches have become standardized and are the subject of two international consensus conferences. Major laparoscopic hepatectomy is currently being evaluated in international multi-center trials. The available data to date would indicate that there is oncological equivalence between open and laparoscopic approaches but that the latter is associated with less post-operative pain, shorter hospital stay and an earlier recovery of full function. Surgeons embarking on this approach must be experienced both in the techniques of advanced liver surgery and in laparoscopic surgery.

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.

Introduction: This study looks at the outcome of 352 patients that underwent the “Manchester groin repair” in the period from 2007 to 2016. The effect of laterality on chronic groin pain and the reduction of pain scores post-surgery are evaluated as well as the rate of hernia recurrence for the inguinal hernia repairs.Methods: The “Manchester groin repair” is a modification of a laparoscopic totally extra-peritoneal approach with fibrin sealant mesh fixation. Data were collected prospectively. In addition to demographic data and the European Hernia Society classification grading of each hernia, pain scores were assessed prior to surgery and at 4–6 weeks post-operatively using a ten-point visual analog pain scale. Data were collected on a bespoke database and differences between time-points analyzed by non-parametric Wilcoxon signed rank tests with Kruskal-Wallis rank sum test for three-group comparisons. Significance was at the P < 0.05 level. The study was undertaken as an institutional audit.Results: Three hundred and fifty two patients underwent TEP repair as per the “Manchester Groin Repair” modification during the period of interest with a median follow-up period of 109.5 (IQR 57.0–318.5) weeks. Of these 274 (77.8%) were for the repair of true hernias and 78 (22.2%) were for inguinal disruptions.All inguinal hernia repairs patients were evaluated (254 m, 20 f); median [interquartile range] age 50 (39–65) years. There were 75 right inguinal hernias (27.4%), 39 Left inguinal hernias (14.2%), and 160 bilateral inguinal hernias (58.4%), giving a total of 434 hernia repairs. During follow-up there were 6 recurrences (1.4%).Of the 274 patients evaluated, 145 (52.9%) had both pre and post-operative pain scores available. Median pre-operative pain score was 5 [IQR 4–7]. Median post-operative pain score was 1 [IQR 1–2]. This difference was significant (P < 0.001). Pre-operative pain scores were higher for those with a bilateral hernia (median 6 vs. 5 and 4, respectively; P = 0.005), but there was no difference in post-operative scores (P = 0.347). One patient (0.3%) presented with chronic groin pain (pain after 3 months).Conclusion: This study demonstrates that the “Manchester groin repair” provides an excellent repair with a low rate of recurrence and low incidence of chronic pain. Longer-term evaluation and larger patient series will add to the understanding of the role of this procedure in groin hernia repair.

- Abstract
A 31-year-old man underwent a laparotomy for acute intestinal obstruction symptoms, which he had intermittently experienced for 14 years. The cause of the obstruction was due to a volvulus of the small bowel caused by a mesenteric lipoma. This is a rare finding, which is ideally diagnosed by computed tomography, with surgery the best and most highly recommended treatment. This particular presentation, to the best of our knowledge, has not yet been previously reported in the English language. [ABSTRACT FROM AUTHOR]

Abstract This review examines the types of material used in hernia repair over the last 50 years and the evolvement of surgical repair techniques. The rates of infection and recurrence associated with past and present materials are also evaluated. In conclusion, while newer materials are associated with fewer complications, close attention to surgical technique is the single most important factor in hernia repair. [ABSTRACT FROM AUTHOR]
