RESUMEN
BACKGROUND: Anal fistula commonly appears after incision and drainage of a perianal abscess. Theoretically, a fistula develops as a consequence of the infection process. Antibiotic treatment was suggested to decrease the possibility of fistula development. OBJECTIVE: We hypothesized that antibiotic treatment has no influence on the development of anal fistula after surgical treatment of perianal abscess. DESIGN: A single-blinded randomized prospective study. SETTINGS: Patients with primary cryptogenic abscesses were eligible to participate. PATIENTS: Patients were divided into 2 groups. Patients in group I received amoxicillin 875 mg/clavulanic acid 125 mg during 7 days after surgery, and patients in group II received no antibiotics. The study database included demographics and clinical and laboratory data. MAIN OUTCOME MEASURES: Patients were examined in our outpatient clinic 2 weeks, 4 months, and 1 year after surgery, and a telephone questionnaire was performed 6 months after surgery. The primary outcome was the formation of anal fistula. The secondary outcome was recurrent perianal abscess. RESULTS: Overall, 98 patients completed the study. Groups were not different in inclusion. Anal fistula was diagnosed in 16 patients (16.3%) in group I (treatment group) and 10 patients (10.2%) in group II (control group; p = 0.67). Nine patients (9.2%) developed recurrent perianal abscess, 4 in the treatment group and 5 in the control group ( p = 0.73). LIMITATIONS: A relatively small number of patients were treated in a single medical center. CONCLUSION: Antibiotic therapy has no influence on anal fistula or recurrent perianal abscess formation after incision and drainage of perianal abscess. See Video Abstract .

Teóricamente, la fístula se desarrolla como consecuencia del proceso infeccioso. Se sugirió tratamiento antibiótico para disminuir la posibilidad de desarrollo de fístula.OBJETIVO:Hipotetizamos que el tratamiento con antibióticos no tiene influencia en el desarrollo de fístula anal después del tratamiento quirúrgico del absceso perianal.DISEÑO:Estudio prospectivo, aleatorio, simple ciego.AJUSTE Y PACIENTES:Los pacientes con absceso criptogénico primario fueron elegibles para participar. Los pacientes se dividieron en dos grupos. Los pacientes del Grupo I recibieron amoxicilina 875 mg/ácido clavulánico 125 mg durante los 7 días posteriores a la cirugía y los pacientes del Grupo II no recibieron antibióticos. La base de datos del estudio incluyó datos demográficos, clínicos y de laboratorio.PRINCIPALES MEDIDAS DE RESULTADO:Los pacientes fueron examinados en nuestra clínica ambulatoria 2 semanas, cuatro meses y 1 año después de la cirugía y se realizó un cuestionario telefónico 6 meses después de la cirugía. El resultado primario fue la formación de una fístula anal. El resultado secundario fue el absceso perianal recurrente.RESULTADOS:En total, 98 pacientes completaron el estudio. Los grupos no fueron diferentes en cuanto a la inclusión. Se diagnosticó fístula anal en 16 (16,3%) pacientes del Grupo I (grupo de tratamiento) y 10 (10,2%) pacientes del Grupo II (grupo control) (p = 0,67). Nueve pacientes (9,2%) desarrollaron absceso perianal recurrente, 4 en el grupo de tratamiento y 5 en el grupo control (p = 0,73).LIMITACIONES:Número relativamente pequeño de pacientes tratados en un solo centro médico.CONCLUSIÓN:La terapia con antibióticos no tuvo influencia sobre la fístula anal o la formación de absceso perianal recurrente después de la incisión y drenaje del absceso perianal.

PURPOSE: Acute gastrointestinal bleeding is a common emergency. Tranexamic acid (TXA) reduces clot breakdown by inhibiting the action of plasmin and has been shown to reduce the need for blood transfusion in trauma, surgical procedures, and upper gastrointestinal bleeding. This study examined the efficiency of intravenous TXA in patients with acute lower gastrointestinal bleeding. METHODS: Eighty-one patients aged >18 years with lower GI hemorrhage, presenting as active rectal bleeding and anemia (hemoglobin lower than 11 g/dL or a decrease of 2 gr/dl from the patient's base level), were enrolled in this single center, double blind prospective research. Patients were randomly assigned to receive intravenous TXA or placebo from admission until colonoscopy took place. The need for transfusion of packed red blood cells (PRBC) and number of units was recorded and compared between the two groups. RESULTS: Eighty-one patients were randomized in this study, thirty-nine in the TXA arm, and forty-two in the placebo arm. Patient characteristics did not differ between the groups. Forty-three out of the 81 patients received blood transfusion; twenty-two were on the placebo arm and twenty-one on the TXA arm (p = 0.89). Twenty-nine patients required 2 or more units, 14 in the TXA arm and 15 in the placebo arm (p = 0.98). CONCLUSIONS: Intravenous TXA has no significant effect on blood requirement in patients with lower GI bleeding. There was no difference in the consumption of PRBC units among the patients in the placebo and TXA groups. It seems that tranexamic acid has no significant effect on transfusion of PRBC units in lower GI bleeding.

BACKGROUND: Contemporary management of patients with synchronous colorectal cancer and liver metastases is complex. The aim of this project was to provide a practical framework for care of patients with synchronous colorectal cancer and liver metastases, with a focus on terminology, diagnosis, and management. METHODS: This project was a multiorganizational, multidisciplinary consensus. The consensus group produced statements which focused on terminology, diagnosis, and management. Statements were refined during an online Delphi process, and those with 70 per cent agreement or above were reviewed at a final meeting. Iterations of the report were shared by electronic mail to arrive at a final agreed document comprising 12 key statements. RESULTS: Synchronous liver metastases are those detected at the time of presentation of the primary tumour. The term 'early metachronous metastases' applies to those absent at presentation but detected within 12 months of diagnosis of the primary tumour, the term 'late metachronous metastases' applies to those detected after 12 months. 'Disappearing metastases' applies to lesions that are no longer detectable on MRI after systemic chemotherapy. Guidance was provided on the recommended composition of tumour boards, and clinical assessment in emergency and elective settings. The consensus focused on treatment pathways, including systemic chemotherapy, synchronous surgery, and the staged approach with either colorectal or liver-directed surgery as first step. Management of pulmonary metastases and the role of minimally invasive surgery was discussed. CONCLUSION: The recommendations of this contemporary consensus provide information of practical value to clinicians managing patients with synchronous colorectal cancer and liver metastases.

PURPOSE: Chronic pain following inguinal hernia repair occurs in up to 20% of patients. The underlying mechanism probably involves sensory nerve damage and abnormal healing that might be influenced by the materials chosen for mesh fixation. The main objective of this study was to compare glue and absorbable tackers on the rate of chronic pain after surgery in patients undergoing totally extraperitoneal inguinal hernia repair (TEP). METHODS: Patients undergoing (TEP) inguinal hernia repair were enrolled in a single-blind randomized clinical trial and were randomized for mesh fixation with glue (LIQUIBAND FIX 8 Neopharm) or absorbable tackers (SECURE STRAP Johnson & Johnson). Pain was assessed using a validated 4-point verbal-rank scale (none, mild, moderate, and severe) at 1 week, 1 month, 6 months, and 1 year postoperatively. Chronic pain was defined as pain persisting beyond 3 months. RESULTS: Two hundred and eight patients were analyzed. The groups were similar in age, gender, and hernia side. Chronic pain of any intensity was reported in 31.7% (66/208) after 6 months and in 13% (29/208) after 12 months. No differences in postoperative pain were observed between the two forms of mesh fixation. Still, when only those with severe pain were considered, mesh fixation with glue resulted in less pain compared to fixation by tackers (log-rank p = 0.025). At 1 year, 4 symptomatic recurrent hernias were identified in patients whose mesh was fixated with absorbable tackers. CONCLUSIONS: Patients who underwent TEP inguinal hernia repair with mesh fixated by glue suffered from less pain.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has had a significant impact on healthcare systems worldwide. The fear of seeking medical attention to avoid the possibility of being infected may have altered the course of some diseases. OBJECTIVES: To describe our experience with the management of patients with acute cholecystitis during the pandemic at our medical center. METHODS: We compared patients treated for acute cholecystitis between 1 March and 31 August 2020 (Group I) to patients admitted with the same diagnosis during the same months in 2019 (Group II). We evaluated demographics, presenting symptoms, laboratory and imaging findings at presentation, the disease's clinical course, management, and outcome. RESULTS: Group I consisted of 101 patients and group II included 94 patients. No differences were noted for age (66 years, IQR 48-78 vs. 66 years, IQR 47-76; P = 0.50) and sex (57.4% vs. 51.1% females; P = 0.39) between the two groups. The delay between symptom onset and hospital admission was longer for Group I patients (3 days, IQR 2-7 vs. 2 days, IQR 1-3; P = 0.002). Moderate to severe disease was more commonly encountered in Group I (59.4% vs. 37.2%, P = 0.003). Group I patients more often failed conservative management (36% vs. 6%, P = 0.001) and had a higher conversion rate to open surgery (15.4% vs. 0%, P = 0.025). CONCLUSIONS: Patients presenting with acute cholecystitis during the COVID-19 pandemic more often presented late to the emergency department and more showed adverse outcomes.

BACKGROUND: Pilonidal sinus is a chronic, inflammatory condition. Controversy exists regarding the best surgical management for pilonidal sinus, including the extent of excision and type of closure of the surgical wound. OBJECTIVES: To assess the short- and long-term outcomes and success rate of the trephine procedure for the treatment of pilonidal sinus. METHODS: A retrospective observational cohort study was conducted at a single center. Patients who underwent trephine procedure between 2011 and 2015 were included. Data collection included medical records review and a telephone interview to establish long-term follow-up. RESULTS: A total of 169 patients underwent the trephine technique for the repair of pilonidal sinus. Follow-up included 113 patients, median age 20 years. Initial postoperative period, 35.6% recalled no pain and 58.6% reported a mild to moderate pain. Postoperative complications included local infection (7.5%) and mild bleeding (15.1%). On early postoperative follow-up, 47.1% recalled no impairment in quality of life, and 25%, 21.2 %, and 6.7% had mild, moderate and sever disturbance respectively. The median time to return to work or school was 10 days. At a median follow-up of 29 months (IQR 19-40), recurrence rate was 45.1% (51/113), and 38 (33.9%) of the patients underwent another surgical procedure Overweight, smoking, and family history were associated with higher recurrence rate. CONCLUSIONS: The trephines technique has a significant long-term recurrence rate. Short-term advantages include low morbidity, enhanced recovery, and minimal to mild postoperative impairment to quality of life. The trephine procedure may be justified as a first treatment of pilonidal disease.

BACKGROUND: Preclinical studies have implicated excess release of catecholamines and prostaglandins in the mediation of prometastatic processes during surgical treatment of cancer. In this study, we tested the combined perioperative blockade of these pathways in patients with colorectal cancer (CRC). METHODS: In a randomized, double-blind, placebo-controlled biomarker trial involving 34 patients, the ß-blocker propranolol and the COX2-inhibitor etodolac were administered for 20 perioperative days, starting 5 days before surgery. Excised tumors were subjected to whole genome messenger RNA profiling and transcriptional control pathway analyses. RESULTS: Drugs were well-tolerated, with minor complications in both the treatment group and the placebo group. Treatment resulted in a significant improvement (P < .05) of tumor molecular markers of malignant and metastatic potential, including 1) reduced epithelial-to-mesenchymal transition, 2) reduced tumor infiltrating CD14+ monocytes and CD19+ B cells, and 3) increased tumor infiltrating CD56+ natural killer cells. Transcriptional activity analyses indicated a favorable drug impact on 12 of 19 a priori hypothesized CRC-related transcription factors, including the GATA, STAT, and EGR families as well as the CREB family that mediates the gene regulatory impact of ß-adrenergic- and prostaglandin-signaling. Alterations observed in these transcriptional activities were previously associated with improved long-term clinical outcomes. Three-year recurrence rates were assessed for long-term safety analyses. An intent-to-treat analysis revealed that recurrence rates were 12.5% (2/16) in the treatment group and 33.3% (6/18) in the placebo group (P = .239), and in protocol-compliant patients, recurrence rates were 0% (0/11) in the treatment group and 29.4% (5/17) in the placebo group (P = .054). CONCLUSIONS: The favorable biomarker impacts and clinical outcomes provide a rationale for future randomized placebo-controlled trials in larger samples to assess the effects of perioperative propranolol/etodolac treatment on oncological clinical outcomes.

Catecholamines and prostaglandins are secreted abundantly during the perioperative period in response to stress and surgery, and were shown by translational studies to promote tumor metastasis. Here, in a phase-II biomarker clinical trial in breast cancer patients (nâ¯=â¯38), we tested the combined perioperative use of the ß-blocker, propranolol, and the COX2-inhibitor, etodolac, scheduled for 11 consecutive perioperative days, starting 5â¯days before surgery. Blood samples were taken before treatment (T1), on the mornings before and after surgery (T2&T3), and after treatment cessation (T4). Drugs were well tolerated. Results based on a-priori hypotheses indicated that already before surgery (T2), serum levels of pro-inflammatory IL-6, CRP, and IFNγ, and anti-inflammatory, cortisol and IL-10, increased. At T2 and/or T3, drug treatment reduced serum levels of the above pro-inflammatory cytokines and of TRAIL, as well as activity of multiple inflammation-related transcription factors (including NFκB, STAT3, ISRE), but not serum levels of cortisol, IL-10, IL-18, IL-8, VEGF and TNFα. In the excised tumor, treatment reduced the expression of the proliferation marker Ki-67, and positively affected its transcription factors SP1 and AhR. Exploratory analyses of transcriptome modulation in PBMCs revealed treatment-induced improvement at T2/T3 in several transcription factors that in primary tumors indicate poor prognosis (CUX1, THRa, EVI1, RORa, PBX1, and T3R), angiogenesis (YY1), EMT (GATA1 and deltaEF1/ZEB1), proliferation (GATA2), and glucocorticoids response (GRE), while increasing the activity of the oncogenes c-MYB and N-MYC. Overall, the drug treatment may benefit breast cancer patients through reducing systemic inflammation and pro-metastatic/pro-growth biomarkers in the excised tumor and PBMCs.

BACKGROUND: Hartmann's reversal is a challenging surgical procedure with significant postoperative morbidity rates. Various surgical methods have been suggested to lower the risk of postoperative complications. In this study, we aimed to compare the postoperative results between open and laparoscopic techniques for Hartmann's reversal. METHODS: A retrospective study of all patients who underwent Hartmann's reversal in five centers in central Israel between January 2004 and June 2015 was conducted. Medical charts were reviewed, analyzing preoperative and operative parameters and short-term postoperative outcomes. RESULTS: 260 patients were included in the study. 76 patients were operated laparoscopically with a conversion rate of 26.3% (20 patients). No differences were found between patients operated laparoscopically and those operated in an open technique regarding gender (p = 0.785), age (61.34 vs. 62.64, p = 0.521), body mass index (26.6 vs. 26.2, p = 0.948), Charlson index score (1.79 vs. 1.95, p = 0.667), and cause for Hartmann's procedure (neoplastic vs. non-neoplastic, p = 0.644). No differences were seen in average time from the Hartmann's procedure to reversal (204.89 vs. 213.60 days, p = 0.688) and in overall complication rate (46.4 vs. 46.5%, p = 1). The Clavien-Dindo score for distinguishing between minor (0-2 score, p = 1) and major complications (3-5 score, p = 0.675) failed to demonstrate an advantage to laparoscopy, as well as to average length of stay (10.91 days in the laparoscopic group vs. 11.72 days in the open group, p = 0.529). An analysis based on the intention-to-treat with laparoscopy, including converted cases in the laparoscopic group, showed similar results, including overall complication rate (48.6 vs. 45.6%, p = 0.68) and Clavien-Dindo score in both minor (p = 0.24) and major complications (p = 0.44). Length of stay (10.92 vs. 11.81 days, p = 0.45) was also similar between the two groups. CONCLUSION: In this series, a laparoscopic approach to Hartmann's reversal did not offer any short-term advantage when compared to an open surgical approach.

BACKGROUND: Preoperative preparation of patients with Crohn's disease is challenging and there are no specific guidelines regarding nutritional support. The aim of this study was to assess whether preoperative nutritional support influenced the postoperative outcome. METHODS: A retrospective, cohort study including all Crohn's disease patients who underwent abdominal surgery between 2008 and 2014 was conducted. Patients' characteristics and clinical and surgical data were recorded and analyzed. RESULTS: Eighty-seven patients were included in the study. Thirty-seven patients (42.5%) received preoperative nutritional support (mean albumin level 3.14 vs. 3.5 mg/dL in the non-optimized group; p < 0.02) to optimize their nutritional status prior to surgery. Preoperative albumin level, after adequate nutritional preparation, was similar between the 2 groups. The 2 groups differ neither in demographic and surgical data, overall post-op complication (p = 0.85), Clavien-Dindo score (p = 0.42), and length of stay (p = 0.1). Readmission rate was higher in the non-optimized group (p = 0.047). CONCLUSION: Nutritional support can minimize postoperative complications in patients with low albumin levels. Nutritional status should be optimized in order to avoid hazardous complications.

BACKGROUND: Damage control laparotomy (DCL) is the widely accepted procedure of choice in management of severely injured trauma patient. It has been implemented in non-trauma-related surgical pathology in the last decade. OBJECTIVES: To evaluate our experience with planned re-laparotomy (PRL) in non-trauma patients and compare it to other reports. METHODS: Charts of all patients admitted to Assaf Harofeh Medical Center who underwent PRL for non-trauma-related abdominal pathology during a 6 year period were reviewed. Data regarding demographics, vital signs, laboratory tests, indications for surgery, length of hospital stay, and mortality were obtained from medical charts. Indications for surgery, risk factors, and mortality were analyzed. RESULTS: The study was comprised of 181 patients. Primary abdominal sepsis (50), postoperative sepsis (49), mesenteric event (32), and intestinal obstruction (28) were the most common indications for PRL. Mortality rate was 48.6%. Factors correlating with increased mortality were advanced age, hypotension, hypothermia, metabolic acidosis, and renal failure. Bowel resection was performed on 122 patients (67%) and primary intestinal anastomosis constructed in 46.7%. Mortality rate was lower in patients who underwent PRL with primary anastomosis compared to patients with postponed bowel anastomosis (33.3% vs. 55.4%, P = 0.018). CONCLUSIONS: PRL in abdominal emergencies carries a high mortality rate. Primary anastomosis may be considered in non-trauma-related PRL.

BACKGROUND: Acute appendicitis (AA) is one of the most common indications for emergency abdominal surgery. OBJECTIVES: To assess the diagnostic and prognostic value of serum bilirubin and liver enzyme levels in the management of acute appendicitis. METHODS: Consecutive emergency department patients referred for a surgical consult for suspected AA were prospectively enrolled in the study. Data regarding demographic, clinical and laboratory results were recorded. Receiver operating characteristic (ROC) curve was performed for all evaluated parameters. Clinical and laboratory markers were evaluated for diagnostic accuracy and correlation to the clinical severity, histology reports, and length of hospital stay. RESULTS: The study was comprised of 100 consecutive patients. ROC curve analysis revealed white blood cell count, absolute neutrophils count (ANC), C-reactive protein, total-bilirubin and direct-bilirubin levels as significant factors for diagnosis of AA. The combination of serum bilirubin levels, alanine transaminase levels, and ANC yielded the highest area under the curve (0.898, 95% confidence interval 0.835-0.962, P<0.001) with a diagnostic accuracy of 86%. In addition, total and direct bilirubin levels significantly correlated with the severity of appendicitis as described in the operative and pathology reports (P < 0.01). Total and direct bilirubin also significantly correlated with the length of hospital stay (P < 0.01). CONCLUSIONS: Serum bilirubin levels, alone or combined with other markers, may be considered as a clinical marker for AA correlating with disease existence, severity, and length of hospital stay. These findings support the routine use of serum bilirubin levels in the workup of patients with suspected AA.

BACKGROUND: The timing of surgical intervention in Crohn's disease (CD) may depend on pre-operative optimization (PO) which includes different interventions to decrease the risk for unfavourable post-operative outcome. The objective of this study was to investigate the effect of multi-model PO on the post-operative outcome in CD. METHOD: This is a multicentre retrospective cohort study. The primary outcome was 30-day post-operative complications. Secondary outcomes were intra-abdominal septic complications, surgical site infection (SSI), re-operation, length of post-operative stay in a hospital and re-admission. PO included nutritional support, discontinuation of medications, pre-operative antibiotic course and thrombosis prophylaxis. RESULTS: Two hundred and thirty-seven CD elective bowel resections were included. Mean age was 39.9 years SD 14.25, 144 (60.8 %) were female and 129 (54.4 %) had one or more types of medical treatment pre-operatively. Seventy-seven patients (32.5 %) optimized by at least nutritional support or change in pre-operative medications. PO patients were more likely to have penetrating disease phenotype (p = 0.034), lower albumin (p = 0.015) and haemoglobin (p = 0.021) compared to the non-optimized. Multivariate analyses showed that treatment with anti-TNF alpha agents OR 2.058 CI [1.043-4.4.064] and low haemoglobin OR 0.741 CI [0.572-0.0.961] increased the risk of overall post-operative complications. Co-morbidity increased the risk of SSI OR 2.567 CI [1.182-5.576] while low haemoglobin was a risk factor for re-admission OR 0.613 CI [0.405-0.926]. Low pre-operative albumin correlated with longer stay in hospital. CONCLUSIONS: PO did not change post-operative outcome most likely due to selection bias. Anti-TNF alpha agents, low haemoglobin, low albumin and co-morbidity were associated with unfavourable outcome.

PURPOSE: Hartmann's procedure is commonly practiced in emergent cases with the restoration of bowel continuity planned at a second stage. This study assessed the rate of restorations following Hartmann's procedure and evaluated factors affecting decision-making. METHODS: Data on patient demographics, comorbidities, causes for Hartmann's procedure, reversal rate, and complications were collected in a multicenter retrospective cohort study of patients who underwent Hartmann's procedure in five medical centers. RESULTS: Six hundred forty patients underwent Hartmann's procedure for diverticular disease (36.1%), obstructing malignancy (31.8%), benign obstruction (5%), and other reasons (23.1%). Overall, 260 (40.6%) patients underwent subsequent restoration of bowel continuity. One hundred twenty-one (46.5%) patients had post-reversal complications, with an average Clavien-Dindo score of 1.4 and a mortality rate of 0.77%. Decision to avoid reversal was mostly related to comorbidities (49.7%) and metastatic disease (21.6%). Factors associated with the decision to restore bowel continuity included male gender (P = 0.02), patient age (62.3 years in Hartmann's reversal patients vs 73.5 years in non-reversal patients; P < 0.0001), number of comorbidities (1.1 vs 1.58; P < 0.001), average Charlson score (1.93 vs 3.44; P < 0.001), and a neoplastic etiology (P < 0.0001). A sub-analysis excluding all patients who died in the 30 days following Hartmann's procedure showed similar factors associated with ostomy closure. CONCLUSION: Many patients do not have restoration of bowel continuity after undergoing Hartmann's procedure. Hartmann's reversal is associated with a significant postoperative morbidity. Surgeons and patients should be aware of the possibility that the colostomy might become permanent.

BACKGROUND: Diagnosis of abdominal lymphadenopathy is challenging when not accompanied by peripheral lymphadenopathy. Computed tomography-guided core-needle biopsy has largely replaced open procedures in recent years, but this approach is limited by access to the anatomic region and the amount of tissue acquired. OBJECTIVES: To demonstrate the feasibility of the laparoscopic approach in obtaining abdominal lymph node biopsies and to evaluate the diagnostic adequacy of the technique. METHODS: We reviewed the data of patients who underwent laparoscopic lymph node biopsy between 2014 and 2014 in our department. Demographics, intra-operative parameters and postoperative course were examined, as were histological reports. Postoperative complications were categorized according to the Clavien-Dindo(CD) classification. RESULTS: Between 2004 and 2014, 57 laparoscopic biopsies were performed for intra-abdominal lymphadenopathy. One case was a repeated attempt due to limited histologic material. The mean age was 49.5 ± 19.6 years. There were two conversions to open laparotomy, one due to small bowel injury and the other due to a sizable mass. Overall, 56 cases had full clinical data: 48 cases (85.7%) had CD=0, six (10.7%) had CD=1, one postoperative severe complication (CD=3) and one mortality (CD=5), which was related to preexisting hepatic insufficiency. Mean hospital stay was 1.6 days. Overall, adequate tissue samples were acquired in 96.7% and only 3 of these cases resulted in inconclusive diagnoses. CONCLUSIONS: Laparoscopic lymph node biopsy is a viable alternative to the currently available methods of tissue retrieval. It provides an access for nodes which are inaccessible percutaneously, and may allow a superior diagnostic yield.

BACKGROUND: Malignant colonic obstruction is commonly treated surgically. Colonic stents are a therapeutic option for palliation or used as a bridge to surgery or chemotherapy. OBJECTIVE: The aim of the study was to evaluate the clinical success rate of stenting as a bridge to one-step surgery, chemotherapy, or as a palliative measure. DESIGN: This was a retrospective observational study. SETTINGS: The study was conducted at a university-affiliated tertiary referral center. PATIENTS AND INTERVENTIONS: From 2007 to 2014, 45 patients with malignant colonic obstruction were referred for stent insertion. MAIN OUTCOME MEASURES: Patients were grouped according to three pre-defined treatment goals: group 1: restorative one-step procedure without an ostomy, group 2: completion of scheduled chemotherapy before surgery, and group 3: palliation without surgical intervention. RESULTS: Group 1 included 11 patients. Three patients (27.3 %) met the treatment goal of one-step surgery. Eight patients (72.7 %) did not reach the primary goal due to stent insertion failure (four patients), stent-related complications (two patients), and failure to perform a one-step surgery after successful stent insertion (two patients). Group 2 included 12 patients. Chemotherapy was successfully completed prior to surgery in six patients (50 %). Six patients (50 %) did not achieve treatment goal due to stent insertion failure (two patients), stent migration (two patients), stent-related perforation (one patient), and mortality (one patient). Group 3 included 20 patients. Long-term palliation without surgical intervention was achieved in eight patients (40 %). Stent insertion failed in seven patients (35 %). Five patients (25 %) needed urgent surgery due to stent complications (three migrations and two perforations). LIMITATIONS: The study was limited by its retrospective nature and small sample size. CONCLUSIONS: This study demonstrates only a modest success rate of colonic stents in the treatment of malignant colonic obstruction. Although colonic stenting seems to be an effective method of relieving colonic obstruction, high failure rates limits its applicability.

BACKGROUND: Contemporary surgical management of complicated diverticulitis is controversial. Traditionally, the gold standard has been resection and colostomy, but recently peritoneal lavage and drainage without resection in cases of purulent peritonitis have been suggested. This study aims to review our initial experience with laparoscopic peritoneal lavage for complicated diverticulitis. METHODS: Retrospective review of all patients who underwent emergent peritoneal lavage and drainage for acute complicated diverticulitis. RESULTS: Five-hundred-thirty-eight patients admitted for acute diverticulitis between 2007 and 2012 were recorded in the database. Thirty seven underwent emergent surgery of which 10 had peritoneal lavage and drainage without colonic resection for complicated diverticulitis causing peritonitis. Peritoneal lavage and drainage resulted in the resolution of acute symptoms in all cases. In long-term follow-up, 3 (30%) patients required elective resection owing to symptomatic disease, two of these due to recurrent diverticulitis, and one owing to complicated fistula following the procedure. CONCLUSION: Peritoneal lavage is a feasible option for complicated diverticulitis with purulent non-fecal peritonitis, but a significant portion of the patients may require elective resection. Comparative studies with emergent resection are needed to determine the role of peritoneal lavage in complicated diverticulitis.

INTRODUCTION: Despite advanced infection control practices including preoperative antibiotic prophylaxis, surgical site infection (SSI) remains a challenge. This study aimed to test whether local administration of a novel prolonged-release Doxycycline-Polymer-Lipid Encapsulation matriX (D-PLEX) before wound closure, concomitantly with standard of care (SOC), reduces the incidence of incisional SSI after elective abdominal colorectal surgery. MATERIALS AND METHODS: This was a phase 3 randomized, controlled, double-blind, multinational study (SHIELD 1) between June 2020 to June 2022. Patients with at least one abdominal incision length >10 cm were randomized 1:1 to the investigational arm (D-PLEX+SOC) or control (SOC) arm . The primary outcome was a composite of incisional SSI, incisional reintervention, and all-cause mortality. RESULTS: A total of 974 patients were analyzed, of whom 579 (59.4%) were male. The mean age (±SD) was 64.2±13.0 years. The primary outcome occurred in 9.3% of D-PLEX patients versus 12.1% (SOC) (risk difference estimate [RDE], -2.8%; 95% CI [-6.7%, 1.0%], P=0.1520). In a pre-specified analysis by incision length, a reduction in the primary outcome was observed in the >20 cm subpopulation: 8% (D-PLEX) versus 17.5% (SOC) (RDE, -9.4%; 95% CI [-15.5%, -3.2%], P=0.0032). In the >10 to ≤20 cm subgroup, no reduction was observed: 9.9% versus 7.9% (RDE, 2.0%; 95% CI [-2.8%, 6.7%], P=0.4133). Exploratory post-hoc analyses of patients with increased SSI risk (≥1 patient-specific comorbidity) indicated a reduction in the incidence of the primary outcome: 9.0% (D-PLEX) versus 13.7% (SOC) (RDE, -4.8%; 95% CI [-9.5%, -0.1%], P=0.0472). The D-PLEX safety profile was good (no difference in treatment-emergent adverse events between the groups). CONCLUSIONS: The SHIELD-1 study did not meet its primary outcome of reduced incisional SSI, incisional reinterventions, or all-cause mortality. Pre-specified and post-hoc analyses suggested that D-PLEX may reduce the incidence of the primary outcome event in patients with increased SSI risk, including lengthy incisions.
RESUMEN
BACKGROUND: There are limited large animal models for the research of novel anastomotic technologies. Subtotal colectomy requires the anastomosis of relatively remote segments of the alimentary tract that are different anatomically, histologically, and pose significant physiological challenge. The quest for a foreign material-free anastomotic line reintroduced nitinol compression anastomosis into clinical use in the last decade. OBJECTIVE: To evaluate the safety, histological, and physiological parameters of side-to-side ileocolic nitinol compression anastomosis in a newly developed large animal model, mimicking the human subtotal colectomy. INTERVENTION: Resection of the entire spiral colon with an ileocolic side-to-side compression anastomosis in 12 animals, compared to resection of a short ileal segment in 6 animals. All anastomoses were constructed by using a novel nitinol-based compression device. The animals were followed up to 30 days postoperatively and were reoperated and sacrificed. RESULTS: All 12 animals underwent successful subtotal colectomy with side-to-side nitinol compression anastomosis. No signs of abdominal infection were found. The increase in the colectomized animals' bodyweight over the postoperative course was significantly lower and the animals presented with longer periods of diarrhea. The histopathology revealed minimal inflammation and foreign body reaction with good alignment of the bowel wall layers in both groups. The anastomotic line width was shown to be reduced during the healing course of the compression anastomoses. CONCLUSIONS: Side-to-side nitinol compression anastomosis is safe and demonstrates favorable functional and histopathological features. The porcine model of subtotal colectomy can be used for further research of novel anastomotic technologies.
