Laparoscopic Surgery or Conservative Treatment for Appendiceal Abscess in Adults? A Randomized Controlled Trial.

We hypothesized that immediate laparoscopic surgery for appendiceal abscess would result in faster recovery than conservative treatment. On the basis of the retrospective studies, conservative management of appendiceal abscess is recommended as a first line treatment, but some controversy exists. Sixty adult patients diagnosed with appendiceal abscess were randomly assigned to either laparoscopic surgery (n = 30) or conservative treatment (n = 30). Hospital stay, recurrences, additional interventions, and complications within 60 days from randomization were recorded. There was no difference in hospital stay: 4 days (interquartile range: 3-5 days) in the laparoscopy group versus 5 days (3-8) in the conservative group, P = 0.105. Patients in the laparoscopy group had 10% risk for bowel resection and 13% risk for incomplete appendectomy. There were significantly fewer patients with unplanned readmissions in the laparoscopy group: 1 (3%) versus 8 (27%), P = 0.026. Additional interventions were required in 2 (7%) patients in the laparoscopy group (percutaneous drainage) and in 9 (30%) patients in the conservative group (surgery), P = 0.042. Recurrent abscesses and failure to respond to conservative treatment were the main reasons for additional interventions. Open surgery was required in 3 (10%) patients in the laparoscopy group and in 4 (13%) patients in the conservative group. Postoperative complications occurred in 3 patients in laparoscopic group versus 2 patients in the conservative group. The rate of uneventful recovery was 90% in the laparoscopy group versus 50% in the conservative group, P = 0.002. Laparoscopic surgery in experienced hands is safe and feasible first-line treatment for appendiceal abscess. It is associated with fewer readmissions and fewer additional interventions than conservative treatment with comparable hospital stay.

How many patients undergoing surgery for perianal abscess or fistula receive a diagnosis of IBD during follow-up?

Background&Aim: Many patients with penetrating Crohn's disease (CD) undergo surgery for perianal disease of presumed cryptoglandular etiology before diagnosis of IBD is established. This study aimed for the first time (1) to determine the frequency of postoperative IBD diagnosis (Dx-POP) among patients undergoing surgery for perianal abscess or fistula, and (2) to identify predictive factors for Dx-POP.

Air embolism case following ERCP

Air embolism is a very rare endoscopic complication (occurs in 1 of 6000 – 8000 procedures) but possesses the potential to be severe and fatal. It is most commonly associated with an ERCP, but it can result from any endoscopic procedure including an gastroscopy, enteroscopy, an EUS, a colonoscopy. Risk factors are previous interventions or surgeries of the bile duct system, transhepatic portosystemic shunt, percutaneous transhepatic biliary drains, blunt or penetrating trauma to the liver, inflammation of the digestive system, sphincterotomy, stent placement, hepatic abscesses or tumors. The patient was a 53-year old female with history of previous acut pencreatitis and abdominal surgery for multiple abscesses and cholecystectomy, ERCP with EST and biliary plastic stent placement. During the procedure we exchanged the former biliary plastic stent. The cardiovascular and neurological symptoms appeared when the patient was repositioned from prone to supine position at the end of the procedure. Computer tomography showed air in vena femoralis communis. The patient's condition improved rapidly in the ICU. In summary, endoscopists should be aware of the signs and symptoms of an air embolism. In patients with risk factors, prophylactic measures can be applied. Increased awareness is essential for prompt recognition of the air embolism, which can allow potentially life-saving therapy to be provided.

Surgery for Pyogenic Brain Abscess over 30 Years: Evaluation of the Roles of Aspiration and Craniotomy.

To evaluate the roles of craniotomy and aspiration in the treatment of pyogenic brain abscess throughout 30 years of computerized tomography. A retrospective study of 224 patients who were surgically treated at Istanbul Medical Faculty, Department of Neurosurgery between 1982 and 2012 was undertaken. The records were analyzed for demographic, clinical and radiological findings, surgical interventions (resection, free-hand aspiration and image-guided aspiration), data regarding abscesses (etiological factors, site, size, number, localization and identified microorganism), corticosteroid and antibiotic usage and complications, and the outcomes were reviewed. The male-to-female ratio was 2.2, and the mean age was 26.2±1.25 years. The most common presenting symptom was headache (56.7%), followed by nausea and vomiting (28.5%). Otitis media and mastoiditis were the most common causes of abscess (41.9%), and 44 patients had multiple abscesses. Aerobic gram-positive microorganisms were the most frequently isolated pathogens in culture (51.5%). Primary surgical interventions were as follows: craniotomy and resection (38.8%), free-hand aspiration (49.1%) and image-guided aspiration (12.1%). The aspiration-to-resection ratio was 1.36 (64/47) in the first decade, 2.94 (50/17) in the second decade and 1 (23/23) in the last decade. Age, level of consciousness at the time of admission and potent corticosteroid usage were found to be significantly associated with mortality (p=0.001, p≤0.001 and p=0,038, respectively). The total morbidity and mortality ratios were 4.9% and 9.8%, respectively. Seizures were more common in patients of craniotomy group (p=0.023). Treatment of pyogenic brain abscess remains challenging, despite advances in surgical and imaging technology, and craniotomy retains a significant role in surgical treatment.

Minimally invasive retroperitoneoscopic surgery for psoas abscess with thoracolumbar tuberculosis.

Minimally invasive retroperitoneoscopic surgery (MIS) for psoas abscess (PA) in patients with thoracolumbar tuberculosis is not well-illustrated and has not reached the status of being fully clinically assessed when we review the English literatures. The aim of this study is to introduce and investigate on efficacy and feasibility of MIS (retroperitoneoscopic technique) for PA in patients with thoracolumbar tuberculosis. From January 2008 to 2013, 39 consecutive patients of the diagnosis of PA with thoracolumbar tuberculosis received the debridement of abscesses and cavity walls of abscesses by the retroperitoneoscopic technique (MIS) in combination with anti-tuberculosis chemotherapy. Medical records and follow-up data were retrospectively studied. CRP and ESR of every patient preoperatively and postoperatively were analyzed Immediate relief in clinical symptoms and signs, and amelioration in imaging and laboratory examinations were obviously observed in all the patients. The follow-up had proceeded for 12-48 (mean 23) months. No complication was observed during the follow-up postoperatively. The retroperitoneoscopic technique for PA gain advantages in terms of shorter hospital stay, minimal invasiveness, absence of radiation, quicker recovery to daily life compared with percutaneous drainage, and anterior or posterior debridement surgery. Despite the technique not been fully clinically proved, it seems to be a recommended option as an effective diagnostic and therapeutic technique for PA, especially with massive or complicated PA.

A retrospective analysis of 93 cases with anorectal abscess in a rural state hospital.

Anorectal abscess is a clinical condition frequently encountered in daily surgical practice and recurrences may occur despite treatment with adequate incision and drainage. The primary aim of this study was to analyze the variables that may have resulted in recurrent anorectal abscess, retrospectively. Ninety-three patients out of 149 patients who underwent surgery for anorectal abscess at our center between 2011-2012 were included in this study. Data regarding age, gender, presence of recurrence, time to recurrence, abscess type, presence of fistula, fistula type, drain usage, length of hospital stay and follow-up duration were retrospectively recorded. Patients were divided into two groups: the recurrence group and the treatment group. Eleven patients (11.8%) had a recurrence and the median time to recurrence was 3 months. None of the variables evaluated were found to be significantly associated with the presence of recurrence. Variables such as age, gender, type of abscess, presence of fistula or drain usage were not associated with the development of recurrence in patients who underwent incision and drainage of an anorectal abscess.

Endoscopic drainage of orbital abscesses aided with intraoperative sonography

Background and purposeAccurate localization and adequate visualization of the superiorly or inferiorly located subperiosteal orbital abscesses or intraorbital abscess is difficult with transnasal endoscopic approach. Sonography is a well-known and effective tool for evaluation of orbital pathologies but no paper documenting intraoperative application of this method in orbital abscess surgery has been published to date. Material and methodsWe present a series of 12 patients in whom orbital abscesses were drained endoscopically with an aid of neuronavigation and intraoperative ultrasonography. The abscesses were localized subperiosteally in the medial (n=6), superior (n=2) or inferior (n=1) part of the orbit whereas in 3 patients the abscess was localized in the intraconal space. ResultsAccording to intraoperative sonographic imaging complete drainage of the abscess was achieved in 11 out of 12 patients and no complications occurred. Intraoperative sonography helped to limit opening of the orbital wall in the medial subperiosteal abscesses, enabled check-up for completeness of drainage of the far extending pouches in the superior and inferior subperiosteal abscesses and enabled visualization of the tip of surgical instrument when reaching deeply located intraorbital abscesses. ConclusionsIntraoperative ultrasonography facilitates the endoscopic management of orbital abscesses, especially those which are difficult to reach due to subperiosteal location in the superior and inferior parts of the orbit, or abscesses localized intraorbitally.

Nephron-Saving Surgery for Abscess of Renal Allograft Using Radiofrequency Bipolar Sealer

Thousands of patients with renal disease are on waiting lists for kidney transplant. Survival and quality of life on hemodialysis are much lower than that after renal transplantation. Renal allografts are extremely valuable and worth saving at all costs. Many complications can be seen after organ transplants on short and long term as rejection, vascular compromise, and infection. There are various reports on partial nephrectomy after renal transplant secondary to de novo masses in the renal allograft. Here, we present a case where we used radiofrequency bipolar sealer for partial nephrectomy for necrotic abscess of the renal allograft. We successfully saved the allograft with partial nephrectomy despite parenchymal infection and necrosis.

Pain Management With Intrathecal Clonidine In Colon Cancer Patient With Opioid Hyperalgesia: Case Presentation

Hyperalgesia is normally an increase in the response to a painful stimulant. Opioid-induced hyperalgesia (OIH) is a situation frequently encountered in algology clinics. Its treatment is complicated and problematic and often requires alternative methods. A 40-year-old male patient 45 kg weighing had been diagnosed with stage IV colon cancer 2.5 years ago. He had used non-steroid antiinflammatory drugs, opioid analgesics and steroid preparations casually for his increased pain without any monitoring for one year. He was admitted five times for pain control. In the last visit, he complained of severe abdominal, pubic and rectal pain (visual analogue scale [VAS] 8), which was unresponsive to epidural analgesic, and later presented to the algology clinic; he was sleep-deprived, restless and in a panic state. Intrathecal morphine (1 mg) was applied considering his opioid tolerance. Because of increased pain (VAS 8-9) one hour after surgery for abscess in the liver and peritonea, the patient was given intravenous dexketoprofen trometamol and diazem considering his OIH. Then, bolus dexmedetomidine (1 µg/kg) followed by dexmedetomidine infusion (0.2 µg/kg/h) was started. Three days later, diagnostic intrathecal clonidine (30 µg) was applied, and the patient's complaints regressed. With the patient reporting relaxed pain (VAS 1-2) after 30 minutes, an intrathecal port was placed. Both cancer pain and OIH were controlled with clonidine 90 µg/day. He was more relaxed, and his pain was tolerable until his death. Intrathecal clonidine administration may be an effective method for the treatment of OIH.

An NSQIP evaluation of practice patterns and outcomes following surgery for anorectal abscess and fistula in patients with and without Crohn's disease.

Background: Patients with Crohn’s disease (CD) are believed to have more aggressive anorectal abscess and fistula disease. We assessed the types of procedures performed and perioperative complications associated with the surgical management of anorectal abscess and fistula disease in patients with and without CD.Methods: The American College of Surgeons National Surgical Quality Improvement Program database (ACS-NSQIP, 2005-2010) was used to calculate 30-day outcomes using regression modeling, accounting for demographics, comorbidities and surgical procedures. ICD-9 codes for anorectal abscess or fistula were used for initial selection. Patients were then stratified, based on the presence or absence of underlying CD. Local procedures included incision and drainage of abscesses, fistulotomy and seton placement. Cutaneous fistulas were considered simple, while all others were classified as complex (-vaginal, -urethral and -vesical).Results: A total of 7,218 patients (mean age 45 years; 64% male) met inclusion criteria, with underlying CD in 345 (4.8%). CD patients were more likely to have a seton placed (9.9 vs 8.2%, P < 0.001) and be on steroids (15.4 vs 4.3%, P < 0.001). Thirty-seven percent of CD patients underwent local procedures, while 46% had a proctectomy and 8% underwent diversion. Fistulotomy was more common in those without underlying CD (16 vs 11%, P < 0.001). The overall complication rate after local treatment was 4.9%, with no difference between patients with and without CD (7.7 vs 4.9%, P = 0.144). This was not affected by fistula type—simple (7.9 vs 3.9%, P = 0.194) vs complex (33 vs 7.1%, P = 0.21)—or when stratified by wound (3.8 vs 2.4%; P = 0.26) or systemic complications (3.8 vs 2.5%; P = 0.53). Yet, complications following emergency procedures were higher in patients with CD (21.4 vs 5.9%, P = 0.047). Factors significantly associated with increased complications were Crohn’s disease (OR = 8.2), lack of functional independence (OR = 2.0), pre-operative weight loss (OR = 2.6) and pre-operative acute renal failure (OR = 5.6). Steroids were also associated with a 1.7-fold increase in complications, independent from CD.Conclusions: While most patients with anorectal abscess/fistula are treated with local procedures, proctectomy and diversion use is fairly common in those with underlying CD. Although complication rates following elective local procedures for anorectal abscess/fistula are similar in patients with and without CD, they are higher in patients on steroids and in CD patients undergoing emergent procedures.

Epidural collection following a late infected total knee replacement — A case report

Prosthetic joint infection is a well-described complication following primary joint replacement. The association between an epidural abscess and joint replacement surgery following the use of epidural anaesthetics has been previously documented. There is however, no report in the literature of an epidural abscess forming as a result of haematogenous spread from an infected prosthetic joint. This case report presents such a scenario and highlights the importance of early diagnosis and treatment of infected prosthetic joints to avoid further systemic complications.

Functional Outcomes and Quality of Life after Anorectal Surgery

There is a paucity of information examining quality of life (QOL) and functional results after anorectal surgery. We aim to prospectively evaluate postoperative QOL, pain, functional outcomes, and satisfaction for a large cohort of patients undergoing anorectal surgery. Data were prospectively accrued for consecutive patients undergoing anorectal operations from June 2009 to September 2010. Preoperative and postoperative electronic questionnaires were completed. QOL was evaluated by the European QOL index (EQ-5D) and functional results with the Fecal Incontinence Severity Index (FISI). Satisfaction was assessed: 1) Are you satisfied with surgery? 2) Would you recommend surgery to others? Responses were reported: 1 to 5 (1 = not at all; 5 = a lot). Pain was scored: 1 (no pain) to 10 (worst). One hundred ninety-five patients, 111 (56.9%) females, median age 44 years (range, 18 to 93 years), underwent anorectal surgery for abscess, condyloma, fissure, fistula, hemorrhoids, incontinence, pilonidal disease, pouch problems, tumors, and prolapse. Overall, pain improved significantly with improved QOL (P = 0.03). This correlated with overall postoperative satisfaction (92.4%). A total of 87.7 per cent of patients would recommend their surgery to others. The FISI was similar pre- and postoperatively (P = 0.18) and did not worsen postoperatively irrespective of surgical indication and procedure. Most patients were satisfied after anorectal surgery, which correlated with improved pain and QOL. Functional outcomes did not worsen. This will help counsel patients preoperatively and allay anxiety about postoperative function.

Function of blood monocytes among patients with orofacial infections

Few data are available on the significance of the integrity of the innate immune system among patients with orofacial infections. This was assessed in the present study. Peripheral blood mononuclear cells (PBMCs) were isolated from 23 patients with orofacial infections before surgical debridement and from 12 healthy volunteers. PBMCs were stimulated with bacterial endotoxin (LPS) and with Pam3Cys. Concentrations of interleukin (IL)-1β, IL-6 and tumor necrosis factor-alpha (TNFα) were estimated in supernatants by an enzyme immunoassay. Concentrations of estimated cytokines released from PBMCs of healthy volunteers and of patients did not differ. Intensity of cytokine release after stimulation was related with the time until complete resolution of the infection (p: 0.046). It is concluded that adequate functions of blood monocytes are associated with favorable outcome after surgery for orofacial abscesses. It seems, however, that impairment of monocyte function predisposes to infection persistence.

Are Pyogenic Liver Abscesses Still a Surgical Concern? A Western Experience

Backgrounds. Pyogenic liver abscess is a rare disease whose management has shifted toward greater use of percutaneous drainage. Surgery still plays a role in treatment, but its indications are not clear. Method. We conducted a retrospective study of pyogenic abscess cases admitted to our university hospital between 1999 and 2010 and assessed the factors potentially associated with surgical treatment versus medical treatment alone. Results. In total, 103 liver abscess patients were treated at our center. The mortality was 9%. The main symptoms were fever and abdominal pain. All of the patients had CRP > 6 g/dL. Sixty-nine patients had a unique abscess. Seventeen patients were treated with antibiotics alone and 57 with percutaneous drainage and antibiotics. Twenty-seven patients who were treated with percutaneous techniques required surgery, and 29 patients initially received it. Eventually, 43 patients underwent abscess surgery. The factors associated with failed medical treatment were gas-forming abscess (P = 0.006) and septic shock at the initial presentation (P = 0.008). Conclusion. Medical and percutaneous treatment constitute the standard management of liver abscess cases. Surgery remains necessary after failure of the initial treatment but should also be considered as an early intervention for cases presenting with gas-forming abscesses and septic shock and when treatment of the underlying cause is immediately required.

Surgery for brain abscess in children with cyanotic heart disease: An anesthetic challenge

Context:Patients with cyanotic congenital heart disease (cCHD) are prone to develop frequent brain abscesses. Surgery for these abscesses is often limited to aspiration under local anesthesia because excision under general anesthesia (GA) is considered a riskier option. Perioperative hemodynamic instability, cyanotic spells, coagulation defects, electrolyte and acid base imbalance, and sudden cardiac arrest are among the major anesthetic concerns. Most of our current knowledge in this area has been gained from a neurosurgical standpoint while there is a paucity of corresponding anesthesia literature.Aims:To highlight the anesthesia issues involved in cCHD children undergoing brain abscess excision under GA.Settings and Design:Retrospective study of our institutional experience over a 5 year period.Materials and Methods:Of all the children with cCHD who underwent brain abscess surgery from January 2005 to December 2009, only 4 were operated under GA. Surgery was done after correcting fever, dehydration, electrolyte imbalance, coagulopathy and acid-base abnormalities, and taking appropriate intraoperative steps to maintain hemodynamic stability and prevent cyanotic spells and arrhythmias. Results: All 4 patients had a successful abscess excision though with varying degrees of intraoperative problems. There was one death, on postoperative day 34, due to septicemia. Conclusions: Brain abscess excision under GA in children of cCHD can be safely carried out with proper planning and attention to detail.

Abstract 16736: Medical vs. Surgical Management of Perivalvular Abscess in Infective Endocarditis: A Propensity Analysis From the International Collaboration on Endocarditis Prospective Cohort Study (ICE-PCS)

Introduction Myocardial abscess is generally regarded as an indication for surgical intervention in infective endocarditis (IE). There is little information, however, comparing outcomes with medical vs. surgical management of such periannular complications of IE. This study used the database of the ICE-PCS to perform a propensity analysis, comparing one year mortality in patients with IE and abscess subjected to either medical or surgical treatment. Methods ICE-PCS enrolled 4794 patients between 2000 and 2006, from 64 centers in 28 countries. There were 699 cases of IE with abscess. A statistical model was built to predict surgery in this cohort.158 patients who underwent surgery for abscess were matched to 158 patients who did not. These 316 patients formed the basis of the analysis. Results In the unadjusted group of 699 patients, the one-year survival with medical treatment was 45%, vs. 67% with surgical management (p&lt;.0001). Differences favoring surgery were similar whether or not the patients had poor prognostic indicators (S. aureus infection; prosthetic valve involvement; CHF). Patients with strep viridans infection, however, had similar survival with medical or surgical management (70%, 14/20 vs.77%, 65/84). In the propensity analysis, the one-year survival with medical management was 44%, compared to 58% in the surgical group (p=.0021). (See graph). Conclusion One-year survival of IE patients with abscess was superior with surgical compared to medical management. These findings support current recommendations that surgical management of perivalvular extension of infection is generally the preferred approach. Patients with strep viridans infection, however, seem to fare equally well with medical or surgical treatment.

Modern History of Surgical Management of Lung Abscess: From Harold Neuhof to Current Concepts

Harold Neuhof was one of the pioneers of thoracic surgery in the early decades of the last century. Inspired by his preceptor Howard Lilienthal he proposed an entirely new concept for surgery on acute lung abscess. The aim of his one-stage procedure was adequate drainage of the abscess cavity. His approach proved to be the first major breakthrough in the treatment of acute lung abscess. Therapy of pulmonary abscess was again radically changed by the advent of antibiotics in the late 1940s. However, the basic principles of Neuhof's concept still influence modern-day management of putrid lung abscess.
