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.
Although most patients with acute pancreatitis have the mild form of the disease, about 20-30% develops a severe form, often associated with single or multiple organ dysfunction requiring intensive ...care. Identifying the severe form early is one of the major challenges in managing severe acute pancreatitis. Infection of the pancreatic and peripancreatic necrosis occurs in about 20-40% of patients with severe acute pancreatitis, and is associated with worsening organ dysfunctions. While most patients with sterile necrosis can be managed nonoperatively, patients with infected necrosis usually require an intervention that can be percutaneous, endoscopic, or open surgical. These guidelines present evidence-based international consensus statements on the management of severe acute pancreatitis from collaboration of a panel of experts meeting during the World Congress of Emergency Surgery in June 27-30, 2018 in Bertinoro, Italy. The main topics of these guidelines fall under the following topics: Diagnosis, Antibiotic treatment, Management in the Intensive Care Unit, Surgical and operative management, and Open abdomen.
Mild appendicitis may resolve spontaneously. The use of CT may lead to an overdiagnosis of uncomplicated appendicitis. The aims of this study were to examine whether early imaging results in more ...patients being diagnosed with acute appendicitis than initial observation, and to study the safety and feasibility of score-based observation compared with imaging in patients with equivocal signs of appendicitis.
Patients with suspected appendicitis with symptoms for fewer than 24 h and an Adult Appendicitis Score of 11-15 were eligible for this trial. After exclusions, patients were randomized openly into two equal-sized groups: imaging and observation. Patients in the imaging group had ultrasound imaging followed by CT when necessary, whereas those in the observation group were reassessed after 6-8 h with repeated scoring and managed accordingly. The primary outcome was the number of patients requiring treatment for acute appendicitis within 30 days.
Ninety-three patients were randomized to imaging and 92 to observation; after exclusions, 93 and 88 patients respectively were analysed. In the imaging group, more patients underwent treatment for acute appendicitis than in the observation group: 72 versus 57 per cent (difference 15 (95 per cent c.i. 1 to 29) per cent). This suggests that patients with spontaneously resolving appendicitis were not diagnosed or treated in the observation group. Some 55 per cent of patients in the observation group did not need diagnostic imaging within 30 days after randomization. There was no difference in the number of patients diagnosed with complicated appendicitis (4 versus 2 per cent) or negative appendicectomies (1 versus 1 per cent) in the imaging and observation groups.
Score-based observation of patients with early equivocal appendicitis results in fewer patients requiring treatment for appendicitis. Registration number: NCT02742402 (http://www.clinicaltrials.gov).
The optimal treatment for diverticulitis with extraluminal air is controversial.
The purpose of this research was to evaluate the safety and effectiveness of nonoperative treatment of acute ...diverticulitis with extraluminal air.
This was a retrospective cohort.
The study was conducted at an academic teaching hospital functioning as both a tertiary and secondary care referral center.
All of the patients with CT-diagnosed acute perforated diverticulitis with extraluminal air from 2006 through 2010 were included in this study.
Nonoperative treatment composed of intravenous antibiotics, bowel rest, and percutaneous drainage were the included interventions.
The need for operative management and mortality were measured.
A total of 132 patients underwent nonoperative treatment, whereas 48 patients were primarily operated on. Patients treated nonoperatively were divided into 3 groups on the basis of identified factors that independently predicted risk for failure: 1) patients with pericolic air (n = 82) without abscess had a 99% success rate with 0% mortality. 2) Patients with distant intraperitoneal air (n = 29) had a 62% success ratewith 0% mortality. Abundant distant intraperitoneal air and fluid in the fossa Douglas were identified as risk factors for failure. Patients without these risk factors had an 86% success rate with nonoperative management. 3) Patients with distant retroperitoneal air (n = 14) had a 43% success rate with 7% mortality.
Comparison of nonoperative versus operative treatment cannot be made because of the study's retrospective nature.
Nonoperative treatment of acute diverticulitis with extraluminal air is safe and effective in patients with a small amount of distant intraperitoneal air or pericolic air without clinical signs of peritonitis.
A common feature of external duodenal fistulae is the devastating effect of the duodenal content rich in bile and pancreatic juice on nearby tissues with therapy-resistant local and systemic ...complications. This study analyzes the results of different management options with emphasis on successful fistula closure rates.
A retrospective single academic center study of adult patients treated for complex duodenal fistulas over a 17-year period with descriptive and univariate analyses was performed.
Fifty patients were identified. First line treatment was surgical in 38 (76%) cases and consisted of resuture or resection with anastomosis combined with duodenal decompression and periduodenal drainage in 36 cases, rectus muscle patch, and surgical decompression with T-tube in one each. Fistula closure rate was 29/38 (76%). In 12 cases, the initial management was nonoperative with or without percutaneous drainage. The fistula was closed without surgery in 5/6 patients (1 patient died with persistent fistula). Among the remaining 6 patients eventually operated, fistula closure was achieved in 4 cases. There was no difference in successful fistula closure rates among initially operatively versus nonoperatively managed patients (29/38 vs. 9/12, p = 1.000). However, when considering eventually failed nonoperative management in 7/12 patients, there was a significant difference in the fistula closure rate (29/38 vs. 5/12, p = 0.036). The overall in-hospital mortality rate was 20/50 (40%).
Surgical closure combined with duodenal decompression in complex duodenal leaks offers the best chance of successful outcome. In selected cases, nonoperative management can be tried, accepting that some patients may require surgery later.
Acute appendicitis (AA) is among the most common causes of acute abdominal pain. Diagnosis of AA is still challenging and some controversies on its management are still present among different ...settings and practice patterns worldwide. In July 2015, the World Society of Emergency Surgery (WSES) organized in Jerusalem the first consensus conference on the diagnosis and treatment of AA in adult patients with the intention of producing evidence-based guidelines. An updated consensus conference took place in Nijemegen in June 2019 and the guidelines have now been updated in order to provide evidence-based statements and recommendations in keeping with varying clinical practice: use of clinical scores and imaging in diagnosing AA, indications and timing for surgery, use of non-operative management and antibiotics, laparoscopy and surgical techniques, intra-operative scoring, and peri-operative antibiotic therapy.
This executive manuscript summarizes the WSES guidelines for the diagnosis and treatment of AA. Literature search has been updated up to 2019 and statements and recommendations have been developed according to the GRADE methodology. The statements were voted, eventually modified, and finally approved by the participants to the consensus conference and by the board of co-authors, using a Delphi methodology for voting whenever there was controversy on a statement or a recommendation. Several tables highlighting the research topics and questions, search syntaxes, and the statements and the WSES evidence-based recommendations are provided. Finally, two different practical clinical algorithms are provided in the form of a flow chart for both adults and pediatric (< 16 years old) patients.
The 2020 WSES guidelines on AA aim to provide updated evidence-based statements and recommendations on each of the following topics: (1) diagnosis, (2) non-operative management for uncomplicated AA, (3) timing of appendectomy and in-hospital delay, (4) surgical treatment, (5) intra-operative grading of AA, (6) ,management of perforated AA with phlegmon or abscess, and (7) peri-operative antibiotic therapy.
Obstruction and perforation due to colorectal cancer represent challenging matters in terms of diagnosis, life-saving strategies, obstruction resolution and oncologic challenge. The aims of the ...current paper are to update the previous WSES guidelines for the management of large bowel perforation and obstructive left colon carcinoma (OLCC) and to develop new guidelines on obstructive right colon carcinoma (ORCC).
The literature was extensively queried for focused publication until December 2017. Precise analysis and grading of the literature has been performed by a working group formed by a pool of experts: the statements and literature review were presented, discussed and voted at the Consensus Conference of the 4th Congress of the World Society of Emergency Surgery (WSES) held in Campinas in May 2017.
CT scan is the best imaging technique to evaluate large bowel obstruction and perforation. For OLCC, self-expandable metallic stent (SEMS), when available, offers interesting advantages as compared to emergency surgery; however, the positioning of SEMS for surgically treatable causes carries some long-term oncologic disadvantages, which are still under analysis. In the context of emergency surgery, resection and primary anastomosis (RPA) is preferable to Hartmann's procedure, whenever the characteristics of the patient and the surgeon are permissive. Right-sided loop colostomy is preferable in rectal cancer, when preoperative therapies are predicted.With regards to the treatment of ORCC, right colectomy represents the procedure of choice; alternatives, such as internal bypass and loop ileostomy, are of limited value.Clinical scenarios in the case of perforation might be dramatic, especially in case of free faecal peritonitis. The importance of an appropriate balance between life-saving surgical procedures and respect of oncologic caveats must be stressed. In selected cases, a damage control approach may be required.Medical treatments including appropriate fluid resuscitation, early antibiotic treatment and management of co-existing medical conditions according to international guidelines must be delivered to all patients at presentation.
The current guidelines offer an extensive overview of available evidence and a qualitative consensus regarding management of large bowel obstruction and perforation due to colorectal cancer.
Hartmann’s procedure is a treatment option for perforated acute diverticulitis, especially when organ dysfunction(s) are present. Its use has been criticized mostly out of fear of high permanent ...stoma rate. The aim of this study was to investigate the rate of stoma reversal, reasons behind nonreversal, and safety of reversal surgery.
This was a single-center retrospective study of patients undergoing urgent Hartmann’s procedure due to acute diverticulitis between the years 2006 and 2017 with follow-up until March 2021.
A total of 3,319 episodes of diverticulitis in 2,932 patients were screened. The Hartmann’s procedure was performed on 218 patients, of whom 157 (72%) had peritonitis (48 (22%) with organ dysfunction). At 2-years, 76 (34.9%) patients had died with stoma, 42 (19.3%) were alive with stoma, and 100 (45.9%) had undergone stoma reversal. The survival of patients with and without reversal were 100% and 42.7% at 1-year, 96.0% and 35.0% at 2-years and 88.9% and 20.7% at 5-years, respectively. The risk factors for nonreversal were old age, a need for outside assistance, low HElsinki Staging for Acute Diverticulitis stage, and higher C-reactive protein level upon hospital admission. The most common reasons for nonreversal in surviving patients were patient not willing to have the operation 18 (41%) and dementia 10 (23%). Twelve (12%) patients had a major complication after reversal (Clavien-Dindo IIIb–IV) and 90-day mortality after reversal was 0%.
After the Hartmann’s procedure for acute diverticulitis, one-third died, half underwent stoma reversal, and one-fifth did not undergo stoma reversal within 2 years. Patients who survive with stoma are either not willing to have reversal or have severe comorbidities excluding elective surgery. The Hartmann’s procedure remains a viable option for high-risk patients with perforated acute diverticulitis.

Skin and soft-tissue infections (SSTIs) encompass a variety of pathological conditions that involve the skin and underlying subcutaneous tissue, fascia, or muscle, ranging from simple superficial ...infections to severe necrotizing infections. SSTIs are a frequent clinical problem in surgical departments. In order to clarify key issues in the management of SSTIs, a task force of experts met in Bertinoro, Italy, on June 28, 2018, for a specialist multidisciplinary consensus conference under the auspices of the World Society of Emergency Surgery (WSES) and the Surgical Infection Society Europe (SIS-E). The multifaceted nature of these infections has led to a collaboration among general and emergency surgeons, intensivists, and infectious disease specialists, who have shared these clinical practice recommendations.
