RESUMO
BACKGROUND: The anatomic variants of the intercostobrachial nerve (ICBN) represent a potential risk of injuries during surgical procedure such as axillary lymph node dissection and sentinel lymph node biopsy in breast cancer and melanoma patients. The aim of this systematic review and meta-analysis was to investigate the different origins and branching patterns of the intercostobrachial nerve also providing an analysis of the prevalence, through the analysis of the literature available up to September 2023. MATERIALS AND METHODS: The protocol for this study was registered on PROSPERO (ID: CRD42023447932), an international prospective database for reviews. The PRISMA guideline was respected throughout the meta-analysis. A systematic literature search was performed using PubMed, Scopus and Web of Science. A search was performed in grey literature through google. RESULTS: We included a total of 23 articles (1,883 patients). The prevalence of the ICBN in the axillae was 98.94%. No significant differences in prevalence were observed during the analysis of geographic subgroups or by study type (cadaveric dissections and in intraoperative dissections). Only five studies of the 23 studies reported prevalence of less than 100%. Overall, the PPE was 99.2% with 95% Cis of 98.5% and 99.7%. As expected from the near constant variance estimates, the heterogeneity was low, I2 = 44.3% (95% CI 8.9%-65.9%), Q = 39.48, p = .012. When disaggregated by evaluation type, the difference in PPEs between evaluation types was negligible. For cadaveric dissection, the PPE was 99.7% (95% CI 99.1%-100.0%) compared to 99.0% (95% CI 98.1%-99.7%). CONCLUSIONS: The prevalence of ICBN variants was very high. The dissection of the ICBN during axillary lymph-node harvesting, increases the risk of sensory disturbance. The preservation of the ICBN does not modify the oncological radicality in axillary dissection for patients with cutaneous metastatic melanoma or breast cancer. Therefore, we recommend to operate on these patients in high volume center to reduce post-procedural pain and paresthesia associated with a lack of ICBN variants recognition.

AIM: The aim of this study was to provide comprehensive evidence-based assessment of the discontinuity of the marginal artery at the splenic flexure (SF) and the rectosigmoid junction (RSJ). METHOD: A systematic review was conducted of literature published to 26 December 2022 in the electronic databases PubMed, SCOPUS and Web of Science to identify studies eligible for inclusion. Data were extracted and pooled into a meta-analysis using the Metafor package in R. The primary outcomes were the pooled PPEs of the marginal artery at the SF and the RSJ. The secondary outcome was the size of vascular anastomoses. RESULTS: A total of 21 studies (n = 2,864 patients) were included. The marginal artery was present at the splenic flexure in 82% (95% CI: 62-95) of patients. Approximately 81% (95% CI: 63-94%) of patients had a large macroscopic anastomosis, while the remainder (19%) had small bridging ramifications forming the vessel. The marginal artery was present at the RSJ in 82% (95% CI: 70-91%) of patients. CONCLUSION: The marginal artery may be absent at the SF and the RSJ in up to 18% of individuals, which may confer a higher risk of ischaemic colitis. As a result of high interstudy heterogeneity noted in our analysis, further well-powered studies to clarify the prevalence of the marginal artery at the SF and the RSJ, as well as its relationship with other complementary colonic collaterals (intermediate and central mesenteric), are warranted.

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.

BACKGROUND: In the last two decades, there has been a Copernican revolution in the decision-making for the treatment of Diverticular Disease. PURPOSE: This article provides a report on the state-of-the-art of surgery for sigmoid diverticulitis. CONCLUSION: Acute diverticulitis is the most common reason for colonic resection after cancer; in the last decade, the indication for surgical resection has become more and more infrequent also in emergency. Currently, emergency surgery is seldom indicated, mostly for severe abdominal infective complications. Nowadays, uncomplicated diverticulitis is the most frequent presentation of diverticular disease and it is usually approached with a conservative medical treatment. Non-Operative Management may be considered also for complicated diverticulitis with abdominal abscess. At present, there is consensus among experts that the hemodynamic response to the initial fluid resuscitation should guide the emergency surgical approach to patients with severe sepsis or septic shock. In hemodynamically stable patients, a laparoscopic approach is the first choice, and surgeons with advanced laparoscopic skills report advantages in terms of lower postoperative complication rates. At the moment, the so-called Hartmann's procedure is only indicated in severe generalized peritonitis with metabolic derangement or in severely ill patients. Some authors suggested laparoscopic peritoneal lavage as a bridge to surgery or also as a definitive treatment without colonic resection in selected patients. In case of hemodynamic instability not responding to fluid resuscitation, an initial damage control surgery seems to be more attractive than a Hartmann's procedure, and it is associated with a high rate of primary anastomosis.

OBJECTIVES: We compared 2 imaging modalities in patients suspected of having coronavirus disease 2019 (COVID-19) pneumonia. Blinded to the results of real-time reverse transcriptase polymerase chain reaction (rRT-PCR) testing, lung ultrasound (LUS) examinations and chest computed tomography (CT) were performed, and the specific characteristics of these imaging studies were assessed. METHODS: From March 15, 2020, to April 15, 2020, 63 consecutive patients were enrolled in this prospective pilot study. All patients underwent hematochemical tests, LUS examinations, chest CT, and confirmatory rRT-PCR. The diagnostic performance of LUS and chest CT was calculated with rRT-PCR as a reference. The interobserver agreement of radiologists and ultrasound examiners was calculated. Ultrasound and CT features were compared to assess the sensitivity, specificity, positive predictive value, and negative predictive value. Positive and negative likelihood ratios measured the diagnostic accuracy. RESULTS: Nineteen (30%) patients were COVID-19 negative, and 44 (70%) were positive. No differences in demographics and clinical data at presentation were observed among positive and negative patients. Interobserver agreement for CT had a κ value of 0.877, whereas for LUS, it was 0.714. The sensitivity, specificity, positive predictive value, and negative predictive value of chest CT for COVID-19 pneumonia were 93%, 90%, 85%, and 95%, respectively; whereas for LUS, they were 68%, 79%, 88%, and 52%. On receiver operating characteristic curves, area under the curve values were 0.834 (95% confidence interval, 0.711-0.958) and 0.745 (95% confidence interval, 0.606-0.884) for chest CT and LUS. CONCLUSIONS: Lung ultrasound had good reliability compared to chest CT. Therefore, our results indicate that LUS may be used to assess patients suspected of having COVID-19 pneumonia.

Background: The current use of endoscopic stenting as a bridge to surgery is not always accepted in standard clinical practice to treat neoplastic colonic obstructions. Objectives: The role of colonic self-expandable metal stent (SEMS) positioning as a bridge to resective surgery versus emergency surgery (ES) for malignant obstruction, using all new data and available variables, was studied and we focused on short- and long-term results. Materials and Methods: A systematic review with meta-analysis was performed. PubMed, SCOPUS and Web of Science databases were included. The search comprised only randomized controlled trials (RCTs) investigating the interventions that included SEMS positioning versus ES. The primary outcomes were the rates of overall postoperative mortality, clinical and technical success. The secondary outcomes were the short- and long-term results. Results: A total of 12 studies were eligible for further analyses. A laparoscopic colectomy was the most common operation performed in the SEMS group, whereas the traditional open approach was commonly used in the ES group. Intraoperative colonic lavage was seldomly performed during ES. There were no differences in mortality rates between the two groups (RR 1.06, 95% CI 0.55 to 2.04; I2 = 0%). In the SEMS group, the rate of successful primary anastomosis was significantly higher in of SEMS (69.75%) than in the ES (55.07%) (RR 1.26, 95% 245 CI 1.01 to 1.57; I2 = 86%). Conversely, the upfront Hartmann procedure was performed more frequently in the ES (39.1%) as compared to the SEMS group (23.4%) (RR 0.61, 95% CI 0.45 to 0.85; I2 = 23%). The overall postoperative complications rate was significantly lower in the SEMS group (32.74%) than in the ES group (48.25%) (RR 0.61, 95% CI 0.41 to 0.91; I2 = 65%). Conclusions: In the presence of malignant colorectal obstruction, SEMS is safe and associated with the same mortality and significantly lower morbidity than the ES group. The rate of successful primary anastomosis was significantly higher than the ES group. Nevertheless, recurrence and survival outcomes are not significantly different between the two groups. The analysis of short- and long-term results can suggest the use of SEMS as a bridge to resective surgery when it is performed by an endoscopist with adequate expertise in both colonoscopy and fluoroscopic techniques and who performed commonly colonic stenting.

BACKGROUND AND OBJECTIVES: Twenty percent of the patients affected with stage IV antropyloric stomach cancer are hospitalized with a gastric outlet obstruction syndrome (GOOS) requiring its resolution to improve the quality of life (QoL). We present our preliminary short- and mid-term results regarding the influence of endoscopic placement of self-expandable metal stent (SEMS) or open stomach-partitioning gastrojejunostomy in QoL. MATERIALS AND METHODS: In this prospective randomized longitudinal cohort trial, we randomly assigned 27 patients affected with stage IV antropyloric stomach cancer into two groups: Group 1 (13 patients) who underwent SEMS positioning and Group 2 (14 patients) in whom open stomach-partitioning gastrojejunostomy was performed. The Karnofsky performance scale and QoL assessment using the EQ-5D-5L™ questionnaire was administered before treatment and thereafter at 1, 3, and 6 months. Results: At 1-month, index values showed a statistically significant deterioration of the QoL in patients of Group 2 when compared to those of Group 1 (p = 0.004; CI: 0.04 to 0.21). No differences among the groups were recorded at 3-month; whereas, at 6-month, the index values showed a statistically significant deterioration of the QoL in patients of Group 1 (p = 0.009; CI: -0.25 to -0.043). CONCLUSIONS: Early QoL of patients affected with stage IV antropyloric cancer and symptoms of GOOS is significantly better in patients treated with SEMS positioning but at 6-month the QoL significantly decrease in this group of patients. We explained the reasons of this fluctuation with the higher risk of re-hospital admission in the SEMS group.

BACKGROUND: A systematic review with a meta-analysis was performed to determine the prevalence and risk factors for secondary de novo adenocarcinoma in the colon used as a urinary diversion not exposed to the fecal stream. METHODS: The systematic review of the literature identified 47 patients with secondary adenocarcinoma in a colonic urinary diversion not exposed to the fecal stream. RESULTS: The diagnosis of secondary adenocarcinoma was determined due to the presence major local symptoms and because the cancer in half of the patients was detected at an advanced stage. Diagnosis at an earlier stage was associated with long-term cancer-free survival. CONCLUSIONS: The authors concluded that cystoscopy-colonoscopy screening as suggested by the American Gastroenterology Society for the general population should be applied to patients who have colon urinary diversion not exposed to the fecal stream. For patients with active high-grade inflammation, difficulty with self-catheterization, or symptoms, cystoscopy should be performed earlier. Resection of the tumor at an early stage offers better clinical outcomes with longer survival rates.

Several surgical sealant devices are commercially available after their rigorous clinical testing with no apparent complications reported so far in the current literature. Cyanoacrylate glue can be used to stabilize the anastomoses and permit a better tensile strength in cardiovascular surgery. We first report the case of a 71-year-old male patient presenting with symptoms of progressive limitation of walking distance, 13 months after a successful femoroinfrapopliteal bypass surgery, because of a calcified tissue extrinsically stenosizing the first segment of the previous bypass graft, caused by the use of cyanoacrylate glue.

An altered balance between metalloproteinases (MMPs) and their inhibitor tissue inhibitor of metalloproteinases (TIMPs) may influence the healing process of a minor amputation following a successful vein graft. To speed up this process, negative pressure wound therapy (NPWT) and advanced moist wound dressing have been proposed. We determined the systemic and local release of MMP-1, -2, -3, -9, TIMP-1, and TIMP-2 by enzyme linked immunosorbent assay (ELISA) technique and their influences in the healing process in 26 patients who underwent minor amputation after a successful revascularisation procedure. Twelve patients (group 1) were medicated with NPWT and 14 (group 2) with advanced moist wound dressing. Plasma samples were collected on the morning of surgery and thereafter at 1, 3, and 5 months; exudates were collected 3 days after surgery when amputation was performed and thereafter at 1, 3, and 5 months. Fifteen age-matched healthy male volunteers served as controls. All wounds healed in 5 ± 0.5 months. Follow-up plasma and local release of MMP-1, -2, -3, and -9 were overall significantly lower when compared with the preoperative levels, while those of TIMP-1 and -2 were significantly higher with no differences among the groups. Despite no differences in the healing process being observed among the two types of medications, at 1 month the local release of MMP-2 and -9 was significantly lower (P = .013 and .047, respectively) and that of TIMP-1 was significantly higher (P = .042) in group 1 as compared to group 2. A correct and aggressive local approach to the wound is able to promote the healing of the lesion stimulating the extracellular matrix turnover with local MMP/TIMP adequate balance and favouring the creation of granulation tissue. However, a successful restoration of an adequate blood flow remains the key point of a durable and rapid wound healing.

BACKGROUND: Whether patients with advanced tubo-ovarian high-grade serous cancer (HGSC) fare better after upfront debulking surgery (UDS) or neoadjuvant chemotherapy with interval debulking surgery (NACT-IDS) remains controversial. METHODS: We studied patients with HGSC who underwent UDS or NACT-IDS between July 2000 and December 2015, with peritonectomy procedures combined with hyperthermic intraperitoneal chemotherapy (HIPEC). Clinical reports were included peritoneal cancer index (PCI), NACT responses, surgical complexity score (SCS), completeness of cytoreduction (CC), complete follow-up with timing, site, and treatment of recurrence. Outcome measures were morbidity, progression-free survival (PFS), PFS2, and overall survival during a mean 5-year follow-up. RESULTS: A total of 34 patients (23.6%) underwent UDS and 110 (76.4%) NACT-IDS both combined with HIPEC. At a median 66.3-month follow-up, patients who underwent UDS or NACT-IDS had similar outcomes. NACT subgroup responses correlated with PCI, SCS, morbidity, and CC. Patients who underwent UDS had lower recurrence rates than those who responded partly or poorly to NACT (PFS, P < .04; PFS2, P < .01). Despite HIPEC, the peritoneal disease recurred in 42.5% of the overall patients. CONCLUSION: In patients with primary HGSC who undergo UDS or NACT-IDS, despite similar outcomes, peritonectomy procedures combined with HIPEC seem unable to prevent peritoneal recurrence.

Visceral aneurysms are rare entities, with a reported incidence of 0.01-2%. Fibromuscular dysplasia is a nonatherosclerotic, noninflammatory artery disease, which may predispose to aneurysmal degeneration. Schizophrenia has been linked to an increased cardiovascular risk because of the influence of traditional and disease-specific risk factors. We report the case of a 44-year-old male schizophrenic patient presenting with a ruptured giant aneurysm of superior mesenteric artery, managed by mesenteric ligation. The histologic diagnosis was fibromuscular dysplasia. Another case of visceral aneurysm in schizophrenic patient with similar histologic features has been previously reported in literature.

Endarterectomy of the common and profunda femoris is currently performed for treatment of atherosclerotic lesions involving femoral bifurcation. Misperception of surgical risk in terms of morbidity and mortality has induced the trend to extend the indication for treatment to patients with mild symptoms at presentation, at the cost of unnecessary increased complication rate and mortality risk, which persists even after patient discharge. We report the case of a giant infected femoral pseudoaneurysm occurring in a 74-year-old patient, previously treated with femoral artery endarterectomy with prosthetic patch closure because of mild claudication. Surgically managed with en block resection and autologous vein reconstruction, his postoperatory course was further complicated by fatal sepsis. Complications for femoral artery endarterectomy, including infectious and fatal events, need a close follow-up of these patients to promptly diagnose and treat any event which may occur, preventing its evolution to more challenging and potentially life-threatening clinical scenario.

BACKGROUND: The femoral prosthetic patch is a surgical procedure frequently used to treat atherosclerotic lesions involving femoral artery bifurcation. Even though it is an easy to perform procedure, surgical management of complications, first of all graft infection, may be challenging, with a high morbidity and mortality risk for patients. We report our experience on surgical treatment of femoral patch infections. MATERIALS AND METHODS: Between April 2012 and April 2018, 26 patients (26 limbs) were referred to the emergency department at our institution for the treatment of femoral prosthetic patch infections. None of the patients had been previously treated at our institution. All patients underwent a wide debridement of the infection site. Blood flow was restored through a vein interposition graft anastomosed at least 4-5 cm from the site of infection. End points of the study were death-related events, major or minor limb loss (major loss for above or below the knee amputation and minor for foot or toe), vein interposition graft failures, recurrent graft infections, or surgical wound healing. RESULTS: A total of 26 patients (21 male and 5 female patients) underwent surgical treatment. The mean age of patients was 69 years. The majority of our patients (54%) had been previously treated with an isolated femoral artery prosthetic patch. Three (11%) patients had been treated with a bilateral prosthetic femoral patch, but only one side was infected. After debridement of the infection site, we used the great saphenous vein to revascularize the lower limb in 22 (85%) cases, whereas the cephalic vein was used in only 4 cases (15%). The 5-year survival rate was 81% (standard error [SE] = 0.12). The 5-year primary patency rate was 70% (SE = 0.14). During follow-up, 4 graft occlusions occurred, and in 2 cases, a major amputation was required. The limb salvage rate at 5 years was 81% (SE = 0.13). CONCLUSIONS: An infection can complicate the femoral prosthetic patch carrying a high rate of morbidity, mortality, and limb loss. Surgical indication for a primary procedure must be restricted to critical limb ischemia, and it must be associated to a multilevel correction of the atherosclerotic disease.

BACKGROUND: An endovascular-first approach to limb salvage and relief from lifestyle-limiting claudication is widely accepted. Stenosis or short occlusion of common, superficial femoral, and popliteal arteries can be corrected with percutaneous transluminal angioplasty (PTA) with stent positioning. Patency rates of these procedures are limited. We report our experience with external iliac artery to the infrapopliteal vessels vein grafts when the endovascular treatment fails. METHODS: Between January 2013 and January 2019, 16 patients (16 limbs) were operated on for limb-threatening ischemia after the occlusion of PTA with stent positioning of the common, superficial femoral, and popliteal arteries. Three patients were treated at our hospital by interventional radiologists; the remaining were operated on elsewhere. An external iliac artery to the infrapopliteal vessels vein bypass graft was anatomically interposed to restore blood flow. End points of the study were death-related events, vein graft failure, and major (above- or below-knee amputation) or minor (foot or toe amputation) limb loss. RESULTS: There were 12 men and 4 women. Mean age of patients was 68 years. Indication for the initial PTA with stent positioning of the common and superficial femoral artery was according to the Rutherford classification Grade I: Category 1, 11 patients (69%) and Category 2, 5 (31%) patients (Stage IIa and IIb according to Fontaine classification, respectively). Great saphenous vein was used in 14 (87%) cases and in 2 (13%) cases a composite graft with a segment of cephalic vein was required. The distal anastomoses were performed on the posterior tibial artery in 6 (37%) cases, anterior tibial artery in 4 (26%), and peroneal artery in 6 (37%). Four-year survival and primary patency rates were 71% (standard error [SE] = 0.15) and 73% (SE = 0.14), respectively. One graft occlusion required an above-knee amputation. Four-year limb salvage rate was 86% (SE = 0.13). DISCUSSION: We recommend the external iliac artery as source of inflow in patients in whom the vein bypass cannot originate from the common femoral or from a more distal inflow source because of previous PTA with stent positioning or it is deemed hazardous.

Prodromal signs of a non-healing wound after revascularisation, which might be strictly linked with impending failure of vascular reconstructions, are associated with an inflammatory response mediated by several circulating adhesion molecules, extracellular endopeptidases, and cytokines. The aim of our study was to investigate the role of selected plasma biomarkers in the prediction of both wound healing and failure of infrapopliteal vein graft or percutaneous trans-luminal angioplasty (PTA) with selective stent positioning of the superficial femoral artery (SFA) in a population affected with critical limb ischaemia. A total of 68 patients who underwent either surgical or endovascular revascularisation of the inferior limb with autologous saphenous vein infrapopliteal bypass or PTA and selective stenting of the SFA were enrolled in our study. Patients were divided into two groups according to treatment: 41 patients were included in Group 1 (open surgery) and 27 in Group 2 (endovascular procedure). Plasma and blood samples were collected on the morning of surgery and every 6 months thereafter for up to 2 years of follow-up or until an occlusion occurred of either the vein bypass graft or the vessel treated endovascularly. Fifteen age-matched healthy male volunteers were considered a reference for biological parameters. Vascular cell adhesion molecule 1 [VCAM-1]/CD106, inter-cellular adhesion molecule-1 [ICAM-1]/CD54), interleukin-1 (IL-1), interleukin-6 (IL-6), tumour necrosis factor alpha (TNF-α), and metalloproteinases (MMP)-2 and -9 plasma levels were measured with enzyme-linked immunosorbent assay (ELISA) kits. The mean observed time to heal of 54 wounds was 13 ± 4 months, with no statistically significant differences among the groups. The healing failure of the remaining wounds was strictly related to an unsuccessful open (n = 12) or endovascular (n = 8) treatment. The 2-year primary patency rate was 65% (SE = .09) in Group 1 and 52% (SE = .1) in Group 2. When compared with mean concentration values of Group 1, VCAM-1 and ICAM-1 were always significantly higher during follow-up in patients of Group 2 (P < .05). Furthermore, in the same group, IL-6 and tumour necrosis factor alpha (TNF-α) were found to be significantly higher at 6- and 12-month (P < .05) when compared with surgically treated patients. Cox regression analysis showed that elevated plasma levels of VCAM-1, ICAM-1, IL-6, and TNF-α during follow up were strongly related to impaired wound healing and/or revascularisation failure (P < .05). Elevated plasma levels of inflammatory markers VCAM-1, ICAM-1, IL-6, and TNF-α may be related to the failure of wound healing and revascularisation procedures. Interestingly, we have observed that endovascular treatments cause a higher level of these inflammation biomarkers when compared with a vein graft, although wound-healing and patency and limb salvage rates are not influenced.
