RESUMO
BACKGROUND: Routine splenic flexure mobilization (SFM) during left hemicolectomy and high anterior rectal resection guarantees a well perfused and tension-free anastomosis, respecting current oncological criteria. According to the recent literature, only 70% of laparoscopic colorectal surgeons considered routine SFM mandatory. Because of its difficulty, SFM increases morbidity including surrounding organs injuries. The goal of the study is to report our experience in avoiding routine SFM during colorectal resection compared to the current surgical state of art. METHODS: Data were collected retrospectively on elective left hemicolectomy without routine SFM performed in our unit between January 2015 to April 2020. Patients were recruited according to diagnosis, histopathology, operative time, ASA score, post-operative morbidity and mortality. RESULTS: Seventy-five oncological patients, underwent to surgery without SFM. The other 13 patients underwent to SFM due to technical issues. The mean operative time was 160.2±44.7 mins, significantly shorter than in patients whose SFM occurred (210.3 min). The morbidity rate was 1%, reintervention occurred in one patient. Eighteen-month median follow-up morbidity was 11% while mortality was 3%. Recurrence rate was of about 5%. CONCLUSIONS: As results from study data analysis, left colectomy can be conducted safely in both laparoscopic and laparotomic approach without SFM in selected cases. As reported in a recent meta-analysis, benefits of avoiding SFM concern reduced operative time without compromising postoperative outcome and respecting oncological criteria, as emerged by our results. Colorectal resection without SFM when is feasible, improves surgical approach reducing technical difficulties and avoiding splenic injuries.
RESUMO
INTRODUCTION: Intussusception occurs when a more proximal portion of the bowel (intussusceptum) invaginates into the more distal bowel (intussuscipiens). The pathomechanism is thought to involve altered bowel peristalsis at the intraluminal lesion, which is then a lead point for the intussusceptum. Intestinal intussusception is rare in adults, accounting for approximately 1 % of all bowel obstructions. We report a unique case in which a partially obstructing sigmoid cancer caused full thickness rectal prolapse requiring surgical intervention. PRESENTATION OF CASE: A 75-year-old male presented in the emergency department due to anal haemorrhage for 5 days. On clinical examination his abdomen was distended with signs of peritoneal irritation in the right quadrants. The CT scan showed sigmoid-rectal intussusception with an sigmoid colonic tumour. The patient underwent emergency anterior resection of the rectum without reduction of the intussusception. Histological examination revealed a sigmoid adenocarcinoma. DISCUSSION: Intussusception is the most common urgent situation among the pediatric population but its incidence in adults is very rare. The diagnosis is difficult to establish with history and physical exam findings alone. Since in adults, unlike children, in most cases a malignant pathology acts as a lead point, the treatment of this pathology still reserves doubts. Recognizing and understanding pertinent signs, symptoms, and imaging findings is essential to the early diagnosis and appropriate management of adult intussusception. CONCLUSION: The appropriate management of adult intussusception is not always clear cut. There is controversy about the reduction before resection in cases of sigmoidorectal intussusception.
RESUMO
AIM: To analyze the minimally invasive surgical maneuvers currently performed to remove pancreatic tail, with or without preservation of the spleen, for benign and borderline malignant neoplasms. MATERIAL AND METHODS: We described operative steps and technical pitfalls encountered during laparoscopic and robotic distal pancreatectomy. The methodology of research focused on recruitment of evidence-based surgical strategies and critical analysis of modern minimally invasive techniques. RESULTS: Laparoscopic and robotic distal pancreatectomy have gradually accepted by pancreatic surgeons and clinical evidences document its growing interest. The choice of patient positioning, port placement, surgical dissection and operative techniques used for pancreatic parenchymal transection is not codified and changes according to personal preference. The technical variability in minimally invasive approach to pancreatic surgery strongly depends depends on surgeon's training and to limited application of these procedures in single institutions. CONCLUSIONS: Pancreatic surgeons worldwide accept laparoscopic and robotic distal pancreatectomy but the best intraoperative praxis is not defined in clinical routine. To date, the pancreatic resection adopts hybrid techniques and the conduction of minimally invasive resection depends to surgeon's experience, patient body habitus and location of pancreatic lesion. Although several technical variations have described, no standardization of the operative minimally invasive surgical method is convincingly built. KEY WORDS: Laparoscopy, Minimally invasive surgery, Pancreas, Robotic pancreatectomy.

BACKGROUND: colorectal cancer (CRC) has a multifactorial etiology which comprises microbiota, genetic predisposition, diet, environmental factors, and last but not least, a substantial contribution by inflammation. The aim of this study is to conduct a systematic review of the literature regarding the strong link between inflammation and colorectal cancer. METHODS: A systematic review of the literature on PubMed (Medline), Scopus, Cochrane and EMBase databases was performed, following the PRISMA 2020 guidelines. Each paper was reviewed by two groups of researchers in a single-blind format by using a pre-planned Microsoft© Excel® grid. RESULTS: Using automated research filters, 14,566 studies were included, but 1% was found significant by the reviewers. Seventy pathways of inflammation were described in the sequence of inflammation-carcinogenesis, and anti-tumorigenic molecules were also found. CONCLUSION: several studies suggest a strong role of inflammation in the tumorigenesis of colorectal cancer through different pathways: this may have a diagnostic and clinical role and also therapeutic purpose in preventing carcinogenesis by treating inflammation. In vitro tests support this theory, even if many other clinical trials are necessary. The present paper was registered in the OpenScience Framework registry (Identifier: DOI 10.17605/OSF.IO/2KG7T).
RESUMO
AIM: Describe a rare case of Richter's hernia with caecum incarceration into a right femoral hernia and provide a narrative literature review about its surgical management. MATERIAL AND METHODS: A 46-year-old woman presented to the Emergency Department and to our surgical unit with a two-days history of worsening abdominal pain in the right lower quadrant without nausea or vomiting, associated with an irreducible lump. Computed tomography of the abdomen described a right inguinal hernia containing small bowel with perivisceral fluid in it without signs of small bowel occlusion nor perforation. RESULTS: A Richter 's femoral hernia with necrotic caecum wall was found but the appendix was not involved. Through a mini-laparotomy, tangential caecal resection and appendectomy were performed. The femoral defect was repaired with a polypropylene mesh-plug placed in the pre-peritoneal space. Postoperative period was uneventful and the patient was discharged on the fifth post-operative day. DISCUSSION: Femoral hernias account for only 2-4% of all groin hernias and occur through a small fascial defect in the femoral canal. Due to its narrowness, it leads to a high risk of incarceration and strangulation thus explaining the increased mortality in the emergency setting (up to 10 fold compared with the elective repair). In some cases, symptoms are no specific and uncommon findings have been reported. Surgical exploration is mandatory in the presence of signs of bowel strangulation or perforation and different approaches (either open or laparoscopically) have been described in literature. CONCLUSIONS: Caecum wall necrosis secondary to an incarcerated Richter's femoral hernia is a rare but dangerous event. Surgical approach is selected on surgeon's expertise. The use of prosthetic mesh is always recommended. KEY WORDS: Bowel necrosis, Emergency surgery, Hernia repair, Richter's hernia.

Neck dissection is a surgical procedure reserved for thyroid cancer cases with clinically evident lymphatic invasion. Although neck dissection is a reliable and safe procedure, it can determine a significant morbidity involving a variety of structures of nervous, vascular and endocrine typology. A careful pre-operative study is therefore essential to better plan surgery. Surgical experience, combined with accurate surgical preparation and merged with adequate and specific techniques, can certainly help reduce the percentage of complications. In recent years, however, technology has also proved to be useful. Its crucial role was already recognized in the safeguard of the integrity of the laryngeal nerve through neuro-monitoring, but new technologies are emerging to help the preservation also of the parathyroid glands and other structures, such as the thoracic duct. These surgical skills combined with the latest technological advancements, that allow us to reduce the incidence of complications after neck dissection for thyroid cancer, will be reported in the present article. This topic is of significant interest for the endocrine and metabolic surgeons' community.
RESUMO
INTRODUCTION: Intussusception is a common condition in children, it is rare in adults. Adult intussusception differs from pediatric intussusception in various respects, including etiology clinical characteristics and therapy. METHODS: We present and discuss a new case of intussusception in children and adults. RESULTS: In child the Barium Enema x-ray examination is identified an endoluminal filling defect to refer to the apex of the invaginated loop at the rectal level, with slow ascent during the progressive injection of the radiopaque contrast medium. At the end of the procedure, incomplete reduction of the picture is documented. The patient undergoes emergency surgery where the presence of an ileo-ceco-colic invagination is documented. Intussusception is reduced by taxis. In the adult laparoscopic right hemicolectomy was performed. High-grade B-cell Burkitt's lymphoma was confirmed by immunohistochemistry. DISCUSSION: In contrast to intussusceptions in children, in the adult population, a demonstrable etiology is found in most of the cases. In adults surgery is always indicated. The non-invasive resolutive intervention most commonly used in the child and best known consists in the rectal introduction of a radiopaque contrast medium (air or barium) at controlled pressure until. CONCLUSIONS: Although intussusceptions occur at all ages, there are major differences in the clinical presentation, diagnostic approach, and management between pediatric and adult populations. Intussusception is remarkably different in these two age groups and it must be approached from a different clinical perspective. KEY WORDS: Intussusception in children, Intussusception in adults, Intussusception symptoms, Radiology and treatment.

BACKGROUND: Laparoscopic reversal of Hartmann's procedure (LHR) offers reduced morbidity compared with open Hartmann's reversal (OHR). The aim of this study is to compare the outcome of laparoscopic versus open Hartmann reversal. MATERIALS AND METHODS: Thirty-four patients who underwent Hartmann reversal between January 2017 and July 2019 were evaluated. Patients underwent either LHR (n = 17) or OHR (n = 17). Variables such as numbers of patients, patient's age, sex, body mass index (BMI), comorbidities, ASA (American Society of Anesthesiology) score, indication for previous open sigmoid resection, mean operation time, rate of conversion to open surgery, length of hospital stay, mortality, and morbidity were retrospectively evaluated. RESULTS: The two groups of patients were homogeneous for gender, age, body mass index, cause of primary surgery, time to reversal, and comorbidities. In 97% of the cases, HP was done by open surgery. Our data revealed no difference in mean operation time (LHR: 180.5 ± 35.1 vs. OHR: 225.2 ± 48.4) and morbidity rate, although, in OHR group, there were more severe complications. Less intraoperative blood loss (LHR: 100 ± 40 mL vs. OHR: 450 ± 125 mL; p value <0.001), shorter time to flatus (LHR: 2.4 days vs. OHR: 3.6 days; p value <0.021), and shorter hospitalization (LHR: 4.4 vs. OHR: 11.2 days; p value <0.001) were observed in the LHR group. Mortality rate was null in both groups. Discussion. LHR is feasible and safe even for patients who received a primary open Hartmann's procedure. We suggest careful patient's selection allowing LHR procedures to highly skilled laparoscopy surgeons.
RESUMO
Trans-duodenal surgical ampullectomy (TSA) was first described in 1899. Nowadays its role in ampullary tumor surgery is still a matter of debate and requires a multidisciplinary approach. The aim of this study is to evaluate the results of TSA as a curative treatment for benign and selected malignant tumors arising from the ampulla in a single-institution experience. Sixteen patients with periampullary tumors that underwent TSA in our surgical units between January 2012 and January 2017 were included in the study. Patient demographic characteristics, pre or postoperative endoscopic interventions, operative procedures, postoperative morbidity and mortality, hospitalization, follow-up time, and quality of life questionnaire were analyzed. Mean operative time was 238.5 min (range 180-390), mean tumor size was 2.3 cm (range 1.5-3.9). The microscopic surgical outcome was R0 for 14 patients. The most frequent findings in terms of histological type were high-grade dysplasia/pTis (43.7%), low-grade dysplasia in 37.5% patients, invasive adenocarcinoma in 2 cases (12.5%), chronic inflammation in 1 case (6.3%). The readmission rate was 18.8% (3/16) and in 2 cases (12.5%) relaparotomy was required. The cumulative median duration of follow-up was 50 months (range 1-96). 90-days mortality was 6.2%. Mean hospital stay was 12 days (range 8-60). Our results confirm that TSA offers good results in terms of morbidity and mortality; still, it remains a challenging procedure that requires particular surgical experience and operative skills. A pre-operative planning in a multidisciplinary board should be carried out prior to the procedure.

Gallbladder agenesis (GA) is a rare embryological anomaly that presents acute cholecystitis like-symptoms. It is often an incidental finding diagnosed during surgery. We reported a case of GA in a patient who presented with dyspepsia and acute right upper abdomen pain with ultrasonographic signs of acute lithiasic cholecystitis. The preoperative assessment, according to first-level exams, is oriented to the diagnosis of acute lithiasic cholecystitis with atrophy and sclerosis. During laparoscopy, the proximal transverse colon was found strictly adherent to gallbladder fossa. The gallbladder was found to be absent. The surgical procedure consisted of lysis of multiple colo-hepatic adhesions. The diagnosis of congenital GA was made laparoscopically. The postoperative radiological images, based on CT and MR examinations, documented the diagnosis of GA with a biliary duct anatomical variant. The recovery was uneventful and the patient remained symptom-free for more than four years. GA is a clinical challenge that still poses diagnostic and therapeutic dilemmas. Although no diagnostic and therapeutic algorithm is accepted worldwide, due to heterogeneity of clinical scenarios and the variability in hospital facilities, surgeons have to be familiar with this rare entity, and conversion in laparotomy or unnecessary operative procedures should be avoided in the same operative setting.
RESUMO
BACKGROUND: Although laparoscopic cholecystectomy (LC) is the gold standard for symptomatic gallbladder disease, a single-incision approach may be a new challenge in order to achieve minimization of surgical trauma. Single-site robotic cholecystectomy (SSRC) is able to offset the ergonomic limitation of laparoscopic single-site cholecystectomy and improves cosmesis. METHODS: We present a single-institution initial experience of SSRC for cholecystolithiasis. Intra-operative and post-operative data of patients were reviewed to assess the technical feasibility and cosmetic outcome. RESULTS: We evaluated a series of 27 consecutive patients retrospectively analyzed and prospectively collected who underwent SSRC. One patient was excluded from the final analysis because they converted to open procedure. The female/male ratio was 17/9, with mean age of 48 ± 12 years. The body mass index mean value was 26.0 ± 4.2. The mean operative time was 99.6 ± 21.5 minutes. No intra- or post-operative complications and readmissions were recorded. At 12 months follow up, every patient received the Body Image Questionnaire (BIQ) and a Photo Series Questionnaire. We recorded three patients (11.5%) with post-operative incisional hernia. Scores of the BIQ subscale for body image perception were 6 ± 1.2, while the scores of scar cosmesis were 21.1 ± 3.0. A statistically significant improvement in scar self-rating from T0 to T1 (P < .01) was found. CONCLUSION: In our initial experience SSRC may be preferred to treat patients with higher needs in terms of cosmesis and body image perception. Lower costs for rent, maintenance and consumables may allow the spread of robotic surgery also for singe site cholecystectomy.

AIM: The cost effectiveness of the laparoscopic right hemicolectomy is still debated, and the current literature does not allow to be drawn certain conclusion. Our study compared direct clinical costs and outcomes for laparoscopic right hemicolectomy with the two most used type of anastomosis, such as ExtraCorporeal Anastomosis (ECA) and IntraCorporeal Anastomosis (ICA). MATERIAL AND METHODS: In this retrospective study, all patients who underwent laparoscopic right hemicolectomy with intracorporeal and extracorporeal anastomosis between January 2016 and April 2018 were evaluated. Patients were divided into two groups according to the type of anastomosis: ECA or ICA. RESULTS: Thirty ECA and twenty-nine ICA patients were included in the study. Operative time was significantly longer in ICA group than ECA group (p < 0.001). No significant differences between the groups were seen in terms of timeto- first flatus, postoperative complications and re-admission rate. ICA group showed a shorter hospitalization (5 vs 6; p < 0.022). In the ICA group, considering only the surgical tools were more expensive than in ECA (1435.6 vs 72 ). Nevertheless, the total cost of the two procedures in similar (14451.36 in ECA group vs 14631.04 in ICA group). CONCLUSION: ECA and ICA are comparable in terms of postoperative outcomes. ICA requires much more expensive charges, compared to a minor hospitalization. The ECA seems to be less expensive in terms of surgical supplies but the longer recovery determines an increase in the total cost resulting in a non-inferiority of one compared to the other technique.

Introduction. Despite the widespread use of the robotic technology, only a few studies with small sample sizes report its application to pancreatic diseases treatment. Our aim is to present the results of a multicenter study on the safety and feasibility of robot-assisted distal pancreatectomy (RDP). Materials and Methods. All RDPs for benign, borderline, and malignant diseases performed in 5 referral centers from 2008 to 2016 were included. Perioperative outcomes were evaluated. Results. Two hundred thirty-six patients were included. Spleen preservation was performed in 114 cases (48.3%). Operative time was 277.8 ± 93.6 minutes. Progressive improvement in operative time was observed over the study period. Conversion rate was 6.3%. Morbidity occurred in 102 cases (43.2%), mainly due to grade A fistulas. Reoperation was required in 10 patients. Postoperatively, 2 patients died of sepsis due to a grade C fistula. Hospital readmission was necessary in 11 cases. A R0 resection was always achieved, with a mean number of 16.2 ± 15 harvested lymph nodes. Conclusion. To our knowledge, this is one of the largest RDP series. Safety and feasibility including the low conversion rate, the high spleen preservation rate, the adequate operative time, and the acceptable morbidity and mortality rates confirm the validity of this technique. Appropriate oncological outcomes have been also obtained.

BACKGROUND: The therapy for differentiated thyroid tumors is currently built upon two cornerstones: the stage of the disease and the new guidelines of the American Thyroid Association, jointly converging to lobohystmectomy for selected cases that meet certain criteria. The aim of the study was to relate these guidelines to the activity of an Italian center with a medium-high volume of thyroidectomies in a region with a high rate of endemic disease of the thyroid. METHODS: In order to conduct the analysis, the clinical records of the last 3 years, including 194 cases of total thyroidectomy and 3 lobohystmectomy, were taken into consideration. There were 46 cases of differentiated thyroid cancer (18 incidental tumors were found during thyroidectomies for benign diseases). Postoperative complications, patient characteristics and the stage of the tumor were assessed in relation to the new ATA guidelines. RESULTS: All patients underwent total thyroidectomy, with 2 of them also undergoing lymphadenectomy. The incidence of transient hypoparathyroidism was 19% with 1 case of permanent deficit. No cases of recurrent nerve injury were reported. Twenty-five out of the 28 patients with cancer preoperatively diagnosed were found with more nodules and in 15 of them the nodule had a diameter bigger than 1 cm. All the parameters suggested lobohystmectomy only for one case. The treatment for the differentiated thyroid tumor is still widely discussed. Above all, differences between populations, screening methods and surveillance programs are still evident. CONCLUSIONS: The ATA guidelines applied to our cases, even if limited, have shown limited applicability to our study, mainly due to the high incidence of multinodularity and the size of the nodule: typical characteristics of a region with a high rate of endemic thyroid pathology.

AIM: Describtion of a rare case of intestinal obstruction due to peritoneal sarcoidosis mimicking peritoneal carcinomatosis, and of the literature review about its surgical management. MATERIAL OF STUDY: A 69 year-old woman was referred to our emergency department with diffuse abdominal pain, enteric vomiting and constipation. Abdominal CT showed a dilatated small bowel loops extended to the jejunum with a mechanical obstruction. Given the failure of a non operative management, an explorative laparotomy was performed. RESULTS: Intraoperative evaluation showed an omental cake with extensive adhesions between small bowel and abdominal wall. The adhesion band determining occlusion was identified and cut. Furthermore, several peritoneal and omental biopsies were performed. Postoperative period was uneventful. Unfortunately, one month later, the patient died following an episode of spontaneous pneumothorax and respiratory complications. DISCUSSION: Sarcoidosis is a chronic multisystemic disorder of unknown aetiology with granulomatous inflammation. Peritoneal involvement is a rare presentation of sarcoidosis. Clinical presentation depends on the extent of organ involvement. In some cases,symptoms are no specific and uncommon findings have been reported so far. CONCLUSION: Despite a peritoneal carcinomatosis was suspeted, this case shows that abdominal sarcoidosis might be considered as a differential diagnosis when a lesion suspected of being peritoneal carcinomatosis shows non-typical clinical presentations. KEY WORDS: Peritoneal sarcoidosis, Small bowel obstruction.

BACKGROUND: Splenic flexure (SF) cancer is not a common condition and its treatment is still under discussion. Although laparoscopic surgery is well accepted for the treatment of colon cancer at any stage, complete mesocolon excision (CME) with selective vascular ligation using the laparoscopic approach for SF cancer remains technically demanding and represents a real challenge for surgeons. METHODS: We present a single-institution experience of laparoscopic CME for SF cancer. Intra-operative, pathologic, and post-operative data of patients who underwent laparoscopic SF resection were reviewed to assess the technical feasibility and oncologic safety. Technical features, histopathology, morbidity, and mortality were evaluated. RESULTS: From February 2015 to October 2017, a minimally invasive approach was proposed to 17 patients (M/F 14/3) affected by splenic flexure cancer. In all patients, the procedure was completed by laparoscopy. The anastomosis was completed intra-corporeally in 89% of cases. The distal margin was 3.1 ± 2.6 cm and the proximal margin was 6.5 ± 3.3 cm from the tumor site. The number of mean harvested nodes was 13.9 ± 7. The mean operative time was 215.5 ± 65 min, and blood loss was 80 ± 27. In one case, a laparoscopic partial gastrectomy was associated due to tumor invasion. The mean post-operative stay was 6.7 ± 3.3 days. Readmission was necessary for two patients. No major morbidity was recorded. CONCLUSIONS: Despite the wide spread and increasing confidence in laparoscopic colectomy, SF resection remains one of the most challenging procedures in colorectal surgery with a complex learning curve. SF resection with CME and CVL is feasible and safe for the treatment of early-stage and locally advanced SF cancer.

INTRODUCTION: Primary NHL (non-Hodgkin lymphoma) of the colon represents only 0.2% to 1.2% of all colonic malignancies. Burkitt's lymphoma (BL) is usually a disease reported in children and young people, most of them associated with EBV or HIV infection. We describe a rare case of intestinal obstruction due to sporadic Burkitt's lymphoma causing ileocaecal invagination explaining our experience Methods. A 31-year-old man presented with diffuse colic pain and weight loss. Clinical examination revealed an abdominal distension with pain in the right iliac fossa. Colonoscopy documented a caecal large lesion with ulcerated mucosa. Computed tomography (CT) have shown a 60 × 50 mm right colic parietal lesion with signs of ileocolic intussusception. RESULTS: Laparoscopic right hemicolectomy was performed. Postoperative period was uneventful. CD20+ high-grade B-cell Burkitt's lymphoma was confirmed by immunohistochemistry (CD20+, CD79+, and CD10+) and FISH test (t (8;14) (q24; q32). The patient was subsequently treated with adjuvant combination chemotherapy (Hyper-CVAD) and is alive and disease-free at 8 months follow-up. DISCUSSION: Adult sporadic Burkitt's lymphoma (BL) causing intestinal obstruction due to ileocaecal intussusception is an extremely rare occurrence and a diagnostic dilemma. Despite the surgical approach is selected based on patient's conditions and surgeon's expertise, minimally invasive method could be preferred.
RESUMO
AIM: Describe a rare case of intestinal obstruction due to sigmoid colon incarceration into a right Spigelian hernia and provide a literature review about its surgical management. MATERIAL OF STUDY: An 88 year-old man presented with a 3-day history of right lower quadrant pain and abdominal distension. Clinical examination revealed a not reducible palpable mass on right side of the anterior abdominal wall. Computed tomography shown signs of intestinal obstruction and a Spigelian hernia of about 3 cm. RESULTS: Sigmoid colon was incarcerated in the defect but no signs of intestinal ischemia was found during the surgical exploration. The hernia content was reduced and the defect was repaired with a polypropylene mesh placed in the pre-peritoneal space. Postoperative period was uneventful and the patient was discharged on the fourth postoperative day. DISCUSSION: Spigelian hernia occurs through congenital or acquired defects in the Spigelian fascia at the level of the semicircular line. Clinical presentation depends on the size and the pattern of the hernia defect. In some cases, symptoms are no specific and uncommon findings have been reported so far. Preoperative establishment of the hernia content and the location of the sac is mandatory to plan a correct surgical strategy. Intestinal incarceration often occurs and suggests a prompt surgical exploration. CONCLUSIONS: Colonic obstruction secondary to an incarcerated Spigelian hernia is a rare but dangerous occurrence. Surgical approach is selected based on patient's conditions and surgeon's expertise. In a non-contaminated surgical field, the use of prosthesis is recommended. KEY WORDS: Intestinal obstruction, Mesh repair, Spigelian hernia.
