RESUMO

Strategies to reduce the postoperative pain in patients undergoing breast cancer surgery include the use of Interpectoral (PECs) block, first described by Blanco in 2011, but its feasibility and efficacy in everyday clinical practice has been debated. The aim of the study was to evaluate the routine feasibility and effectiveness of PECs block added to general anesthesia to reduce postoperative pain and opioids consumption in the Breast Unit's patients. From June to December 2021 all patients undergoing surgery were included to receive PECs1 block before general anesthesia; clinical and outcome data were prospectively collected. Fifty-eight out of 61 patients undergoing major or minor procedures were enrolled. The average time of block execution was 93.56 s (SD 42.45), with only one minor complication reported. Very low doses of intra and postoperative opioids consumption were reported, regardless of the type of surgery. The pain NRS resulted under the median value of 1 point [IQR 3] in the early postoperative period to 0 at 24-48 h, with beneficial effects lasting at least for two weeks, since no opioids consumption in the postoperative period had been reported, only 31% of patients required paracetamol with a dosage of 0.34 g (SD 0.548); comparison between type of surgery and different regimens of general anesthesia were reported. Routine use of PECs block, in addition to general anesthesia, was found to be safe, feasible and effective, resulting in low intraoperative opioids consumption, very low postoperative pain and analgesic requirement, with effects lasting up to two weeks after surgery.

RESUMO

BACKGROUND: This Italian multicentric retrospective study aimed to investigate the possible changes in outcomes of patients undergoing surgery for gastrointestinal cancers during the COVID-19 pandemic. METHOD: Our primary endpoint was to determine whether the pandemic scenario increased the rate of patients with colorectal, gastroesophageal, and pancreatic cancers resected at an advanced stage in 2020 compared to 2019. Considering different cancer staging systems, we divided tumors into early stages and advanced stages, using pathological outcomes. Furthermore, to assess the impact of the COVID-19 pandemic on surgical outcomes, perioperative data of both 2020 and 2019 were also examined. RESULTS: Overall, a total of 8250 patients, 4370 (53%) and 3880 (47%) were surgically treated during 2019 and 2020 respectively, in 62 Italian surgical Units. In 2020, the rate of patients treated with an advanced pathological stage was not different compared to 2019 (P = 0.25). Nevertheless, the analysis of quarters revealed that in the second half of 2020 the rate of advanced cancer resected, tented to be higher compared with the same months of 2019 (P = 0.05). During the pandemic year 'Charlson Comorbidity Index score of cancer patients (5.38 ± 2.08 vs 5.28 ± 2.22, P = 0.036), neoadjuvant treatments (23.9% vs. 19.5%, P < 0.001), rate of urgent diagnosis (24.2% vs 20.3%, P < 0.001), colorectal cancer urgent resection (9.4% vs. 7.37, P < 0.001), and the rate of positive nodes on the total nodes resected per surgery increased significantly (7 vs 9% - 2.02 ± 4.21 vs 2.39 ± 5.23, P < 0.001). CONCLUSIONS: Although the SARS-CoV-2 pandemic did not influence the pathological stage of colorectal, gastroesophageal, and pancreatic cancers at the time of surgery, our study revealed that the pandemic scenario negatively impacted on several perioperative and post-operative outcomes.

RESUMO

Here we present the case of a 17-year-old male patient, affected by Asperger syndrome, who reached the emergency division of our hospital after anal insertion of some stylus batteries. Transanal extraction of 30 stylus batteries avoided surgical intervention. Lockdown and boredom due to the strict domestic quarantine policies adopted during COVID-19 pandemic might have unmasked in our patient a susceptibility to unhealthy behaviour.

RESUMO

Here we present the case of a 29-year-old female patient who underwent to laparoscopic reduction of idhiopatic jejuno-jenunal intussusception, a very rare cause of intestinal obstruction in adults. Laparoscopic exploration represents the best approach in adults. Unfortunately, manoeuvres of laparoscopic reduction are difficult and conversion to laparotomy is often needed.

RESUMO

INTRODUCTION: Brunner's gland hamartoma (BGH) is an infrequently encountered, benign, polypoid proliferation of Brunner's glands. Usually these lesions are asymptomatic, just only occasionally presenting with duodenal obstruction or bleeding signs and mimicking a tumoral lesion. CASE PRESENTATION: A 72-year-old male, referred for recurrent vomiting and epigastralgia, was investigated and all preoperative findings were suggestive of a tumour of the duodenum. During the scheduled pancreaticoduodenectomy a mass, resultant to a polyp, was palpatory felt inside the duodenum and then successfully and completely resected through a duodenotomy avoiding surgical overtreatment and connected postoperative morbidities. Histological analysis showed hyperplasia of Brunner's glands correspondent to a Brunner's gland hamartoma. BGH was undiagnosed before surgery, due to its particular sub-mucosal growth simulating an expanding process starting from the duodenum, and secondly due to unsuccessful biopsies performed during endoscopic procedure. CONCLUSION: BGH is a rare lesion featuring, when symptomatic, obstructive or bleeding symptoms. Surgical treatment represents the gold standard approach in case of lesions that are technically impossible to remove endoscopically or in case of an undiagnosed lesion. Herein, we report a case of a patient presenting with a duodenal lesion mimicking, in all preoperative findings, a tumour of the duodenum. Duodenotomy and resection of the BGH provided a definitive cure avoiding surgical overtreatment. An intraoperative deep analysis of all surgical cases still remain crucial for a right therapeutic choice even in a new era for surgical technology. For similar intraoperative findings we recommend this technique.

RESUMO

There is still an unmet clinical need for small-caliber artery substitution. Decellularized scaffolds in tissue engineering represent a promising solution. We have developed an innovative system for the automatic decellularization of blood vessels, used to process pig arteries. The system is able to automatically drive a decellularization process in a safe and reliable environment, with complex time patterns, using up to three different decellularization solutions, and providing at the same time a physical stress to improve the decellularization. The decellularization of pig arteries was evaluated by means of histology, DNA quantification and mechanical testing. Outcomes showed scaffolds with no cellular or nuclear remnants and a well-preserved tissue structure, corroborated by mechanical properties similar to native tissue. Decellularized scaffolds were seeded on the inner layer with human endothelial cells and implanted as iliac artery replacement in 4 pharmacologically immune-compromised pigs. This chimeric model was performed as a very preliminary evaluation to investigate the performances of these scaffolds in vivo, and to investigate the fate of seeded cells. Recipients were sacrificed on day 14 and day 70 after surgery, and vessels were found to be patent and with no evidence of thrombi formation. The inner layer was covered by endothelial cells, and the migration of cells positive for α-smooth-muscle actin was observed from the outer layer towards the tunica media. Intriguingly, the endothelial cells on explanted vessels were entirely derived from the host while the seeded cells were lost. In conclusion, this work presents a novel tool for a safe and controlled production of arterial scaffolds, with good decellularization outcomes and a good performance in a short-term, large-animal implantation.

RESUMO

BACKGROUND: Acute generalized peritonitis secondary to complicated diverticulitis is a life-threatening condition; the standard treatment is surgery. Despite advances in peri-operative care, this condition is accompanied by a high peri-operative complication rate (22%-25%). No definitive evidence is available to recommend a preferred surgical technique in patients with Hinchey stage III/IV disease. METHODS: A matched case-control study enrolling patients from four surgical units at Italian university hospital was planned to assess the most appropriate surgical treatment on the basis of patient performance status and peritonitis exposure, with the aim of minimizing the surgical site infection (SSI). A series of 1,175 patients undergoing surgery for Hinchey III/IV peritonitis in 2003-2013 were analyzed. Cases (n=145) were selected from among those patients who developed an SSI. THE CASE: control ratio was 1:3. Cases and control groups were matched by age, gender, body mass index, and Hinchey grade. We considered three surgical techniques: T1=Hartman's procedure; T2=sigmoid resection, anastomosis, and ileostomy; and T3=sigmoid resection and anastomosis. Six scoring systems were analyzed to assess performance status; subsequently, patients were divided into low, mild, and high risk (LR, MR, HR) according to the system producing the highest area under the curve. We classified peritonitis exposition as P1=<12 h; P2=12-24 h; P3=>24 h. Univariable and multivariable analyses were performed. RESULTS: The Apgar scoring system defined the risk groups according to performance status. Lowest SSI risk was expected when applying T3 in P1 (OR=0.22), P2 (OR=0.5) for LR and in P1 (OR=0.63) for MR; T2 in P2 (OR=0.5) in LR and in P1 (OR=0.61) in MR; T1 in P3 (OR=0.56) in LR; in P2 (OR=0.63) and P3 (OR=0.54) in MR patients, and in each P subgroup (OR=0.93;0.97;1.01) in HR. CONCLUSIONS: Pre-operative assessment based on Apgar scoring system integrated with peritonitis exposure in complicated diverticulitis may offer a ready-to-use tool for reducing SSI-related complications and applying appropriate treatment, reducing the need for disabling ostomy.

RESUMO

Since Baskin et al. reported the first documented case of failure of a laparoscopically-induced ventriculoperitoneal shunt (VP) in 1998, the cerebrospinal fluid shunt has been generally considered a relative contraindication to laparoscopy. Although the literature is limited there is a small body of evidence indicating that it is safe to perform laparoscopic surgery on these patients with routine anaesthetic monitoring. In this study we report the case of a laparoscopic cholecystectomy in the presence of a ventriculoperitoneal shunt. A review of the literature suggests that laparoscopic cholecystectomy can be safely performed in patients with a ventriculoperitoneal shunt. The only related contraindication should be if a catheter has recently been placed.

RESUMO

AIM: To evaluate and discuss all the potential complications affecting morbidity of patients treated with surgery for primary achalasia. MATERIAL OF STUDY: A review of the available English literature published to date has been conducted. All articles reporting surgical experience in achalasia were examined and then were selected only those specifically inherent to the topic at issue. RESULTS: Mucosal perforation is the main intra-operative complication while persistence or recurrence of the disease and gastro-esophageal reflux are those mostly affecting patients afterwards, even at long-term follow-up. A few other less common morbidities, as well as the technical considerations useful to minimize and manage each complication mentioned, are reported. DISCUSSION: Minimally invasive surgery for achalasia consent to treat patients with a low rate of perioperative complications that can be managed with conservative approach in the majority of cases. Risk of esophageal cancer exists in these patients and remains although surgical therapy. CONCLUSIONS: Laparoscopic Heller myotomy along with partial fundoplication is a safe and effective procedure that should be considered as the treatment of choice at first evaluation of achalasic patients rather than endoscopic techniques. Robotic technology may add further contribution in diminishing perioperative complications.

RESUMO

Small caliber vessels substitutes still remain an unmet clinical need; few autologous substitutes are available, while synthetic grafts show insufficient patency in the long term. Decellularization is the complete removal of all cellular and nuclear matters from a tissue while leaving a preserved extracellular matrix representing a promising tool for the generation of acellular scaffolds for tissue engineering, already used for various tissues with positive outcomes. The aim of this work is to investigate the effect of a detergent-enzymatic decellularization protocol on swine arteries in terms of cell removal, extracellular matrix preservation, and mechanical properties. Furthermore, the effect of storage at -80°C on the mechanical properties of the tissue is evaluated. Swine arteries were harvested, frozen, and decellularized; histological analysis revealed complete cell removal and preserved extracellular matrix. Furthermore, the residual DNA content in decellularized tissues was far low compared to native one. Mechanical testings were performed on native, defrozen, and decellularized tissues; no statistically significant differences were reported for Young's modulus, ultimate stress, compliance, burst pressure, and suture retention strength, while ultimate strain and stress relaxation of decellularized vessels were significantly different from the native ones. Considering the overall results, the process was confirmed to be suitable for the generation of acellular scaffolds for vascular tissue engineering.

RESUMO

OBJECTIVES: Decellularized biological scaffolds represent a promising solution for tissue engineering. They offer a good substrate for cells in terms of biochemical composition, ultrastructure and mechanical properties without generating an immunogenic response. The aim of this study was to design and develop a device for the automatic decellularization of biological tissues to overcome manual operation limits, toward a good manufacturing practice-compliant process. METHODS: A versatile, modular and easy-to-use device was designed, able to automatically exchange decellularization fluids and to provide mechanical shaking according to a user-defined protocol. Preliminary decellularization tests were made on porcine abdominal aortas comparing results between conventional process and device-operated process using water, sodium deoxycholate and DNase. Vessels were processed up to 4 cycles of the protocol and after each decellularization cycle histological analyses (hematoxylin-eosin, Movat pentachrome and DAPI stainings) were observed. Preliminary mechanical tests were also performed to compare the mechanical behavior of blood vessels processed with the 2 methods mentioned above. RESULTS: Briefly, the device consists of decellularization chambers, a shaking system and hydraulic modules for the exchange of fluids. The device was bench-tested for functionality and reliability with positive outcomes. The protocol used revealed to be effective, with a progressive tissue decellularization through repeated cycles. No difference between manual and automated operation was observed in histological or mechanical analyses. CONCLUSIONS: The developed device is able to automate the decellularization process lowering operator-related risks, and is a reliable and functional tool for clinical use.

RESUMO

The aim of the study was to analyze the frequency of incidental thyroid carcinoma (unknown tumor smaller than or equal to 10 mm) in a consecutive series of 462 total thyroidectomies for multinodular goiter and to investigate the clinical risk factors for this type of malignancy. A retrospective, single-center study of outcome data collected from patients with preoperative diagnosis of multinodular goiter who underwent total thyroidectomy at the General Surgery Unit of Pavia (Italy) between January 2000 and December 2008 was performed. Possible risk factors for malignancy were: gender, age, time of evolution of goiter, presence of a dominant nodule in multinodular goiter, hyperthyroidism, history of radiation to the neck, residence in an area of endemic goiter, prior thyroid surgery, calcifications in the goiter detected by neck ultrasound or chest X-rays, and a family history of thyroid diseases. In a 9-year period, 462 patients underwent total thyroidectomy. We found 41 cases of incidental thyroid carcinoma; the most common histopathological type was papillary. The multivariable analysis demonstrated that the clinical variables associated with occult carcinoma were a personal history of radiation therapy to the neck, the presence of calcifications detected by ultrasound or neck X-rays, and a family history of thyroid diseases; residence in an area of endemic goiter was a protective factor. A personal history of radiation to the neck, detection of calcifications by ultrasound or by neck X-rays, and a family history of thyroid diseases should be considered clinical risk factors for malignancy in multinodular goiter.

RESUMO

HYPOTHESIS: Hand-assisted laparoscopic surgery (HALS) is a safe therapeutic approach to remove megaspleens of any size. Conventional laparoscopic splenectomy for splenomegaly is difficult because of limited exposure and complex vascular control, with increased risk of intraoperative bleeding and conversion to open surgery. HALS can overcome some of these limitations, reducing the risk of conversion to open surgery and resulting in a postoperative course similar to that of conventional laparoscopy. DESIGN: Single-institution single-surgeon retrospective review. SETTING: University hospital. PATIENTS: An analysis was performed of all patients with splenomegaly (splenic weight, >700 g) seen during a 10-year period. MAIN OUTCOME MEASURES: Preoperative data, indications for splenectomy, splenic weight, operative variables, clinical outcome, and rates of conversion to open surgery, complications, and operative mortality were compared between patients undergoing HALS vs conventional laparoscopy. RESULTS: Splenomegaly was present in 85 patients, of whom 43 underwent HALS splenectomy and 42 underwent conventional laparoscopic splenectomy. The HALS group had larger spleens. Rates of conversion to open surgery and operative mortality were similar in the HALS group vs the conventional laparoscopy group (2.3% [1 of 43] vs 2.4% [1 of 42] and 2.3% [1 of 43] vs 0.0% [0 of 42], respectively), with no difference in hospital length of stay in the absence of morbidity. Portal system thrombosis was the most serious complication. CONCLUSIONS: HALS can minimize surgical trauma in patients with massive splenomegaly who otherwise would be candidates only for open surgery and results in a clinical outcome similar to that of conventional laparoscopy. With the availability of HALS, any patient with splenomegaly can be offered a minimally invasive surgical option. Portal system thrombosis is common, regardless of the surgical technique.

RESUMO

Reported herein is an unusual vascular tumor primary arising in the liver and exhibiting unique histopathological features. A 47-year-old woman underwent left hepatectomy because of a large hepatic mass. On histology the tumor had a composite pattern, consisting of angiomatous, retiform and solid areas, formed by oval to cuboidal to spindle cells, that expressed only endothelial markers (CD31 and factor VIII-related antigen). These findings led to the diagnosis of a low-grade vascular neoplasm with morphological features consistent with so-called polymorphous hemangioendothelioma. The tumor was completely resected. At 24 month follow up the patient was alive, without evidence of disease. Polymorphous hemangioendothelioma is a rare vascular neoplasm, with borderline malignant potential, which usually occurs in lymph nodes and, rarely, at extranodal sites. Its classification as an entity has been questioned recently. The unusual morphological features of the present case, which do not fit neatly with any other recognized hemangioendothelioma subtype, indicate that the family of vascular tumors is broader than currently accepted. In addition the present case widens the spectrum of primary vascular tumors arising in the liver.

RESUMO

Fibromatosis-like spindle-cell metaplastic carcinoma (FLSpCC) is an atypical variant of spindle-cell carcinoma with a particular clinical behavior characterized by frequent local recurrence, very low potential for axillary lymph node metastasis, and uncommon distant metastases. Although it presents the typical immunoprofile of basal-like carcinomas, FLSpCC is associated with a favorable clinical outcome and conservative treatment is generally indicated. Because of the lack of specific clinical and radiological characteristics, the criteria for the differential diagnosis from other benign and malignant tumors are based only on histological findings and immunostaining. We report on two FLSpCC patients treated with wide local excision and mastectomy associated with axillary lymph node dissection. Although the biological behavior of this subtype of breast cancer has not been adequately evaluated, wide local excision or mastectomy with clear resection margins but no axillary dissection appears to be an adequate treatment approach.
