Percutaneous cholecystostomy as bridge to surgery vs surgery in unfit patients with acute calculous cholecystitis: A systematic review and meta-analysis.

BACKGROUND: Acute cholecystitis is one of the most common causes of acute abdomen. Early laparoscopic cholecystectomy is the gold standard treatment, still burdened by a risk of intraoperative biliary duct injury. An alternative strategy to manage patients with severe acute cholecystitis is the percutaneous gallbladder drainage (PGBD). METHODS: The Italian Society of Emergency Surgery and Trauma performed a systematic review and meta-analysis with the aim to clarify controversies about the preoperative use of PGBD. We extracted 32 studies: 9 Randomized Control Trial Studies (RCTs) and 23 no RCTs. RESULTS OF CRITICAL OUTCOMES: The incidence of post-operative complications was lower in the PGBD associated at LC than in the LC alone (RCTs: RR 0.28, 95% CI 0.14 to 0.56, I2 = 63%). The incidence of the post-operative biliary leakage was higher in late PGBD' group (RCTs: RR 0.18, 95% CI 0.04 to 0.80). RESULTS OF OTHER OUTCOMES: The incidence of intraabdominal abscess, blood loss, conversion to open, subtotal cholecystectomy, operative time and wound infection was lower in PGBD' group. The total hospital stay was the same. CONCLUSION: A strong recommendation is performed to the use of the PGBD + LC than upfront LC to reduce biliary leakage (recommendation "strong positive") in high risk acute cholecystitis especially in patients with higher perioperative risks or longstanding acute cholecystitis. For post-operative complications a recommendation "positive weak" suggests that PGBD + LC could be used than upfront LC to reduce the rate of post-operative complications.

Asymptomatic inguinal hernia: does it need surgical repair? A systematic review and meta-analysis.

BACKGROUND: The aim of this review is to compare the outcomes of surgical repair versus watchful waiting in asymptomatic or minimally symptomatic inguinal hernias. METHODS: Preferred reporting items for systematic reviews and meta-analyses guidelines were employed. We analysed primary outcomes: pain, quality of life, pain during daily activities and visual analogue scale (VAS that measures pain at rest and on movement) and secondary outcomes: postoperative complications and recurrence. RESULTS: Pain and quality of life were not comparable due to differences in the parameters used in different articles. Pain interfering with normal daily activity was evaluated in one study and appears more favourable in the post-repair group respect to the watchful waiting (WW) group (5.1% versus 2.2%). VAS, measured in one study, at 6 months was more favourable in the surgery group (37% versus 44%). After 12 months the outcome was better in the control group than in the repair group (28% versus 30%). Conversion rate of the patient cohorts from watchful waiting to elective surgery was between 35.03% and 57.8%. The meta-analysis did not find significant statistical differences in the two groups examined for postoperative complications [RR = 0.95, 95% CI (0.50, 1.80), P = 0.88], as for hernia recurrence [RR = 1.01, 95% CI (0.50, 2.02), P = 0.98]. CONCLUSION: WW seems to be an acceptable option for the patient with asymptomatic or minimally symptomatic inguinal hernias. Delaying surgical repair until symptoms appear is safe. Acute hernia incarcerations are not particularly frequent. The incidence of chronic pain after the repair is high. Physicians must select patients carefully and explain to them the risks and benefits of surgery.

Injuries during Laparoscopic Cholecystectomy: A Scoping Review of the Claims and Civil Action Judgements.

BACKGROUND: To define what type of injuries are more frequently related to medicolegal claims and civil action judgments. METHODS: We performed a scoping review on 14 studies and 2406 patients, analyzing medicolegal claims related to laparoscopic cholecystectomy injuries. We have focalized on three phases associated with claims: phase of care, location of injuries, type of injuries. RESULTS: The most common phase of care associated with litigation was the improper intraoperative surgical performance (47.6% ± 28.3%), related to a "poor" visualization, and the improper post-operative management (29.3% ± 31.6%). The highest rate of defense verdicts was reported for the improper post-operative management of the injury (69.3% ± 23%). A lower rate was reported in the incorrect presurgical assessment (39.7% ± 24.4%) and in the improper intraoperative surgical performance (21.39% ± 21.09%). A defense verdict was more common in cystic duct injuries (100%), lower in hepatic bile duct (42.9%) and common bile duct (10%) injuries. CONCLUSIONS: During laparoscopic cholecystectomy, the most common cause of claims, associated with lower rate of defense verdict, was the improper intraoperative surgical performance. The decision to take legal action was determined often for poor communication after the original incident.

The Management of Acute Colonic Diverticulitis in the COVID-19 Era: A Scoping Review.

Background and Objective: During the COVID-19 pandemic, health systems worldwide made major changes to their organization, delaying diagnosis and treatment across a broad spectrum of pathologies. Concerning surgery, there was an evident reduction in all elective and emergency activities, particularly for benign pathologies such as acute diverticulitis, for which we have identified a reduction in emergency room presentation with mild forms and an increase with more severe forms. The aim of our review was to discover new data on emergency presentation for patients with acute diverticulitis during the Covid-19 pandemic and their current management, and to define a better methodology for surgical decision-making. Method: We conducted a scoping review on 25 trials, analyzing five points: reduced hospital access for patients with diverticulitis, the preferred treatment for non-complicated diverticulitis, the role of CT scanning in primary evaluation and percutaneous drainage as a treatment, and changes in surgical decision-making and preferred treatment strategies for complicated diverticulitis. Results: We found a decrease in emergency access for patients with diverticular disease, with an increased incidence of complicated diverticulitis. The preferred treatment was conservative for non-complicated forms and in patients with COVID-related pneumonia, percutaneous drainage for abscess, or with surgery delayed or reserved for diffuse peritonitis or sepsis. Conclusion: During the COVID-19 pandemic we observed an increased number of complicated forms of diverticulitis, while the total number decreased, possibly due to delay in hospital or ambulatory presentation because of the fear of contracting COVID-19. We observed a greater tendency to treat these more severe forms by conservative means or drainage. When surgery was necessary, there was a preference for an open approach or a delayed operation.

Aspiration versus peritoneal lavage in appendicitis: a meta-analysis.

BACKGROUND: Acute appendicitis is one of the most frequent abdominal surgical emergencies. Intra-abdominal abscess is a frequent post-operative complication. The aim of this meta-analysis was to compare peritoneal irrigation and suction versus suction only when performing appendectomy for complicated appendicitis. METHODS: According to PRISMA guidelines, a systematic review was conducted and registered into the Prospero register (CRD42020186848). The risk of bias was defined to be from low to moderate. RESULTS: Seventeen studies (9 RCTs and 8 CCTs) were selected, including 5315 patients. There was no statistical significance in post-operative intra-abdominal abscess in open (RR 1.27, 95% CI 0.75-2.15; I2 = 74%) and laparoscopic group (RR 1.51, 95% CI 0.73-3.13; I2 = 83%). No statistical significance in reoperation rate in open (RR 1.27, 95% CI 0.04-2.49; I2 = 18%) and laparoscopic group (RR 1.42, 95% CI 0.64-2.49; I2 = 18%). In both open and laparoscopic groups, operative time was lower in the suction group (RR 7.13, 95% CI 3.14-11.12); no statistical significance was found for hospital stay (MD - 0.39, 95% CI - 1.07 to 0.30; I2 = 91%) and the rate of wound infection (MD 1.16, 95% CI 0.56-2.38; I2 = 71%). CONCLUSIONS: This systematic review has failed to demonstrate the statistical superiority of employing intra-operative peritoneal irrigation and suction over suction-only to reduce the rate of post-operative complications after appendectomy, but all the articles report clinical superiority in terms of post-operative abscess, wound infection and operative times in suction-only group.

Therapeutic options for body packers: surgical or conservative treatment? A single center experience and review of literature.

UNLABELLED: Body packing is a way to deliver packages of drugs hidden in body cavities. In Europe, as noted the latest report coming from the Brussels observatory, there are 74 million drugs consumers. Italy is in pole position and Perugia was considered as a "capital city" in the drug market. Body packers usually swallow the drug packets, although their insertion into the rectum and vagina has also been reported. The management depends on whether or not the patient becomes symptomatic. Surgery is indicated in presence of repeated bouts of drug toxicity not controlled by medical treatment, radiological evidence of packet retention in the stomach, intestinal obstruction or perforation. It is also important to emphasize that, in a multidisciplinary context, the patient's management before reaching the operating theater if symptomatic, is aimed to stabilization and is usually demanded to Intensive Care Unit (ICU) physicians. We present our center recent experience with body packers, managed both with surgical and conservative treatments. KEY WORDS: Body packers, Drugs, Emergency surgery, Foreign bodies.

A rare nosological entity: the perforated solitary cecal diverticulum. Research article.

AIM: To describe three cases of solitary cecal diverticulum, and trying to evaluate the better method of diagnosis and treatment with analysis of the literature. MATERIAL OF STUDY: Description of three cases of solitary cecal diverticulum's perforation admitted in the Department of General and Oncologic Surgery, Santa Maria della Misericordia Hospital, Perugia, during the period January 2011 - January 2012. RESULTS: In all patients the clinical presentation was very similar to that of acute appendicitis. Preoperative diagnosis was achieved in one case through abdominal CT scan, other two cases were identified at final pathology. At one year from the treatment all patient are still alive. DISCUSSION: Cecal diverticulum is a rare condition, often diagnosed either casually or because of inflammatory or perforative complications. The highest incidence is found in Western population. Because of the clinical presentation, very similar to the appendicitis, and the inflammatory reaction involving the colon and its surrounding tissues, the pre- and intra-operative diagnosis are very difficult. The diagnosis is almost always histological. The treatment may vary from simple expectant medical management, carried out with bowel rest, parenteral support and antibiotics as for left-sided diverticulitis, to surgical approach, performed through simple diverticulectomy or by classical right hemicolectomy. CONCLUSION: Pre-surgical and, also intra-operative, diagnosis of perforated solitary cecal diverticulum is clearly difficult. CT scan represents the gold standard for the differential diagnosis. Right hemicolectomy is an effective and safe approach, allowing accurate control, preventing complications and recurrences, and it represents the optimal management of the disease.

Incidental finding of carcinoid tumor on Meckel's diverticulum: case report and literature review, should prophylactic resection be recommended?

Meckel's diverticulum (MD) is the most common congenital anomaly of the gastrointestinal tract and is caused by incomplete obliteration of the vitelline duct during intrauterine life. MD affects less than 2% of the population. In most cases, MD is asymptomatic and the estimated average complication risk of MD carriers, which is inversely proportional to age, ranges between 2% and 4%. The most common MD-related complications are gastrointestinal bleeding, intestinal obstruction and acute phlogosis. Excision is mandatory in the case of symptomatic diverticula regardless of age, while surgical treatment for asymptomatic diverticula remains controversial. According to the majority of studies, the incidental finding of MD in children is an indication for surgical resection, while the management of adults is not yet unanimous. In this case report, we describe the prophylactic resection of an incidentally detected MD, which led to the removal of an occult mucosal carcinoid tumor. In literature, the association of MD and carcinoid tumor is reported as a rare finding. Even though the strategy for adult patients of an incidental finding of MD during surgery performed for other reasons divides the experts, we recommend prophylactic excision in order to avoid any further risk.

The integrated role of ultrasonography in the diagnosis of soft tissue metastases from melanoma: preliminary report of a single-center experience and literature review.

Currently melanoma has the fastest growing incidence of all cancers in men and the second in women (after lung cancer) in Western countries. Since prognosis of skin melanoma is excellent in early stages but dramatically worsens in advanced stages, an early diagnosis is fundamental in granting patients a favorable outcome. Sentinel node (SN) biopsy represents the gold standard for accurately staging melanoma, but other tests are commonly endorsed both in the initial staging work-up and in the follow-up, such as ultrasonography, computed tomography (CT)-scan and positron emission tomography (PET)-CT. PET-CT, among others, has high sensitivity and specificity for the study of distant metastases, the assessment of soft tissues and lymph node involvement, and for the guidance of surgical biopsies. Ultrasonography (US) is a non-invasive procedure whose use has recently expanded in our service, both preoperatively, intraoperatively and postoperatively, thanks to its wide availability, low costs and easy and fast reproducibility; ultrasonography even surpassed the reliability of PET-CT or CT-scan in the seven cases presented herein. US is operator-dependent, and this is probably the major limitation of the procedure, together with lack of prospective studies validating its strength, but our preliminary study demonstrates that ultrasound can assume an important role in melanoma, both for staging and the follow-up of patients, especially with lymph nodal or subcutaneous involvement.

Spontaneous splenic rupture in patient with metastatic melanoma treated with vemurafenib.

BACKGROUND: BRAF inhibitors such as vemurafenib are a new family of biological drugs, recently available to treat metastatic malignant melanoma. METHODS: We present the case of a 38-year-old man affected by metastatic melanoma who had been under treatment with vemurafenib for a few days. The patient suffered from sudden onset of abdominal pain due to intra-abdominal hemorrhage with profuse hemoperitoneum. An emergency abdominal sonography confirmed the clinical suspicion of a splenic rupture. RESULTS: The intraoperative finding was hemoperitoneum due to splenic two-step rupture and splenectomy was therefore performed. Histopathology confirmed splenic hematoma and capsule laceration, in the absence of metastasis. CONCLUSIONS: This report describes the occurrence of a previously unreported adverse event in a patient with stage IV melanoma receiving vemurafenib.
