Neuroendocrine tumors' patients treated with somatostatin analogue could complicate with emergency cholecystectomy.

BACKGROUND: Gastro-entero-pancreatic neuroendocrine tumors are gradually seeing their incidence increase, probably due to their low-rate mortality. Surgery and subsequent medical therapy through octeotride and somatostatin analogues is the recommended approach for hypersecretive hormonal forms, showing an effective control of symptoms and improved survival outcomes. AIM: The present study aims to evaluate the occurrence of gallbladder lithiasis, and its complications, in patients underwent upfront surgery for neuroendocrine tumors and subsequent long-term administration of somatostatin analogues. MATERIAL OF STUDY: We included four adults affected by neuroendocrine (gastric, appendiceal and ileal) tumors and without previous evidence of gallbladder stones, who needed an emergency cholecystectomy after long-term somatostatin treatment. RESULTS: The patients showed complicated conditions sustained by cholelithiasis, such as acute cholecystitis, gangrenous cholecystitis, or intestinal occlusion, which required emergency surgery. DISCUSSIONS: Somatostatin analogues may influence the cascade of enzymes that guarantee the gallbladder motility, and consequently cause the precipitation of cholesterol and calcium bilirubinate crystals. Therefore, higher and sustained levels of somatostatin may result in higher rates of gallstone development. CONCLUSIONS: The prophylactic cholecystectomy, during upfront surgery for neuroendocrine tumors, might prevent an emergency cholecystectomy for gallstones complications. KEY WORDS: Gallbladder stones, Neuroendocrine tumors, Somatostatine analogues.

Current Trends in Volume and Surgical Outcomes in Gastric Cancer.

Gastric cancer is ranked as the fifth most frequently diagnosed type of cancer. Complete resection with adequate lymphadenectomy represents the goal of treatment with curative intent. Quality assurance is a crucial factor in the evaluation of oncological surgical care, and centralization of healthcare in referral hospitals has been proposed in several countries. However, an international agreement about the setting of "high-volume hospitals" as well as "minimum volume standards" has not yet been clearly established. Despite the clear postoperative mortality benefits that have been described for gastric cancer surgery conducted by high-volume surgeons in high-volume hospitals, many authors have highlighted the limitations of a non-composite variable to define the ideal postoperative period. The textbook outcome represents a multidimensional measure assessing the quality of care for cancer patients. Transparent and easily available hospital data will increase patients' awareness, providing suitable elements for a more informed hospital choice.

The Emergency Surgery Frailty Index (EmSFI) in Elderly Patients with Acute Appendicitis: An External Validation of Prognostic Score.

BACKGROUND: Identification of reliable risk-stratification tools is critical for surgical decision making, particularly in frail and elderly. The aim of the study is to validate the Emergency Surgery Frailty Index (EmSFI), in over 65 years old patients operated on for acute appendicitis. METHODS: An observational study was conducted enrolling elderly patients with diagnosis of acute appendicitis who underwent emergency appendicectomy or right colectomy, between 2016 and 2021. All patients were treated according to the last SIFIPAC/WSES/SICG/SIMEU guidelines. RESULTS: Overall, 61 patients were analyzed. Complication rate was higher for patients in the second EmSFI risk Class. Moreover, ROC analyses identified 3 as the best cutoff value in predicting risk of adverse postoperative events. Complication rate was higher in oldest elderly patients-over 80 years-(42.9 vs 22.5%; p 0.05) and was mainly related to medical complications (42.9 vs 12.5%, p 0.007). However, intestinal obstruction, peri-appendicular abscess on preoperative CT, peritonitis and a longer duration of surgery are related with increased risk of complications in the group of patients under 80 years. CONCLUSION: The EmSFI score results a valid prognostic marker for frailty status, and it may support the surgeon in emergency setting for acute appendicitis. Patients aged 80 years or older have a higher risk of complications, independent from those factors which relate to increased morbidity in younger elderly patients. Age alone is not a reliable indicator of the real surgical risk, but it must encourage the adoption of multidisciplinary collaborative models of care for this group of patients.

Extended Lymphadenectomy for Gastric Cancer in the Neoadjuvant Era: Current Status, Clinical Implications and Contentious Issues.

Despite its decreasing incidence, gastric cancer remains an important global healthcare problem due to its overall high prevalence and high mortality rate. Since the MAGIC and FNLCC/FFCD trials, the neoadjuvant chemotherapy has been recommended throughout Europe in gastric cancer. Potential benefits of preoperative treatments include a higher rate of R0 resection achieved by downstaging the primary tumor, a likely effect on micrometastases and isolated tumor cells in the lymph nodes, and, as a result, improved cancer-related survival. Nevertheless, distortion of anatomical planes of dissection, interstitial fibrosis, and sclerotic tissue changes may increase surgical difficulty. The collection of at least twenty-five lymph nodes after neoadjuvant therapy would seem to ensure removal of undetectable node metastasis and reduce the likelihood of locoregional recurrence. It is not what you take but what you leave behind that defines survival. Therefore, para-aortic lymph node dissection is safe and effective after neoadjuvant chemotherapy, in both therapeutic and prophylactic settings. In this review, the efficacy of adequate lymph node dissection, also in a neoadjuvant setting, has been investigated in the key studies conducted to date on the topic.

Management and Treatment of External Hemorrhoidal Thrombosis.

Background: External hemorrhoidal thrombosis (EHT) is a common complication of hemorrhoidal disease. This condition causes extreme pain, likely resulting from internal anal sphincter hypertonicity, which traps the hemorrhoids below the dentate line thus leading to congestion and swelling. The choice of treatment remains controversial and both conservative and surgical options have been proposed in the last decades. Methods: This mini-review focuses on the most relevant studies found in literature evaluating conservative and surgical management of EHT. Special conditions such as pregnancy and EHT in elderly patients have been considered. Results: Traditionally, symptoms duration represents the discriminant in the choice between medical and surgical treatment. Several Coloproctological Societies considered conservative treatment as the first-line approach to EHT and a variety of options have been proposed: wait and see, mixture of flavonoids, mix of lidocaine and nifedipine, botulinum toxin injection and topical application of 0.2% glyceryl trinitrate. Meanwhile, different surgical treatments are recommended when EHT fails to respond to conservative management or when symptoms onset falls within the last 48-72 h: drainage with radial incision, conventional excision, excision under local anesthesia and stapled technique. Conclusion: The management and treatment of EHT is still controversial since no specific guidelines have been published. Both medical and surgical treatment have been proven effective but randomized clinical trials and structured consensus-based guidelines are warranted.

Antimicrobial Prophylaxis Reduces the Rate of Surgical Site Infection in Upper Gastrointestinal Surgery: A Systematic Review.

Surgical site infection occurs with high frequency in gastrointestinal surgery, contributing to the high incidence of morbidity and mortality. The accepted practice worldwide for the prevention of surgical site infection is providing single- or multiple-dose antimicrobial prophylaxis. However, most suitable antibiotic and optimal duration of prophylaxis are still debated. The aim of the systematic review is to assess the efficacy of antimicrobial prophylaxis in controlling surgical site infection rate following esophagogastric surgery. PubMed and Cochrane databases were systematically searched until 31 October 2021, for randomized controlled trials comparing different antimicrobial regimens in prevention surgical site infections. Risk of bias of studies was assessed with standard methods. Overall, eight studies concerning gastric surgery and one study about esophageal surgery met inclusion criteria. No significant differences were detected between single- and multiple-dose antibiotic prophylaxis. Most trials assessed the performance of cephalosporins or inhibitor of bacterial beta-lactamase. Antimicrobial prophylaxis (AMP) is effective in reducing the incidence of surgical site infection. Multiple-dose antimicrobial prophylaxis is not recommended for patients undergoing gastric surgery. Further randomized controlled trials are needed to determine the efficacy and safety of antimicrobial prophylaxis in esophageal cancer patients.

Transanal hemorrhoidal dearterialization (THD) for hemorrhoidal disease: An Italian single-institution 5-year experience analysis and updated literature review.

Background: Hemorrhoidal disease is a highly prevalent, chronic disorder that usually compromise patients' quality of life. Despite recent advances in pharmacologic and surgical therapeutic options, a clear treatment "gold standard" is lacking. Our aim is to analyze the outcomes following Transanal Hemorrhoidal Dearterialization (THD) procedure. Methods: Patients who failed conservative treatment and underwent THD Doppler between 2017 and 2021 were enrolled. Follow-up interviews (consisting of clinical examination, Visual Analog Scale for pain-VAS, Vaizey incontinence score, Hemorrhoid Severity Score) were administered 1 week, 2 weeks, 1 month and 6 months after surgery. Results: Forty-seven out of 75 patients were male, and the mean age was 50 (± 17.9) years. Hemorrhoids were classified as Goligher's degree II in 25 cases, III in 40 and IV, simple irreducible without ischemic changes, in 10. The mean operative time was 35 (28-60) minutes, and most procedures were performed with epidural anesthesia (80%). No intraoperative complications occurred, and 73 patients (97.3%) were discharged within post-operative day 1. Early post-operative pain and bleeding occurred in 37.3% and 8% of patients, respectively. No patients experienced anal incontinence and severe symptoms at 6 months after surgery. The overall success rate was 97.3%. Conclusions: THD is safe and effective in hemorrhoidal disease at degree II if bleeding, III, and IV without ischemic changes, both as a first intervention and on recurrence. Physician and patient need to understand each other's expectations, weight the risks and benefits, and customize the treatment.

To Keep or Not to Keep? The Hamletic Umbilical Dilemma: Preservation versus Reconstruction of the Umbilicus in Vertical Abdominoplasty.

(1) Background: The role of the umbilical scar and its repositioning remains one of the most important surgical steps in the execution of any type of abdominoplasty, including those involving "inverted-t" or "fleur de lys" incisions. A consequence of this is a surgeon's Hamletic dilemma: to keep or not to keep the original umbilical scar? (2) Methods: A retrospective observational study was conducted on all patients undergoing "T-inverted" abdominoplasty at the Department of Plastic Surgery of the Santa Maria alle Scotte University Hospital, Siena, between January 2018 and December 2020. Twelve months after the surgery we submitted to all patients the U-score questionnaire about their feelings about their umbilicus's appearance. Patients could assign a score from 1 (very dissatisfied) to 4 (very satisfied) to each of the five items of the score. (3) Results: The average of the scores attributed by the nine patients in whom the navel was preserved is 13 (Range 10-17), while in patients on whom a navel reconstruction was performed, the mean score is 16.8 (Range 12-20). The mean score of patients with a reconstructed umbilicus is, therefore, statistically higher than that of the other group of patients (t-value = 3.88, p = 0.000374) with an average increase of 3.8 points. (4) Conclusions: We can state that the reconstruction of a new navel is the right answer to the Hamletic dilemma in patients having undergone vertical or anchor abdominoplasty.

Robotic versus laparoscopic gastrectomy for gastric cancer: protocol for umbrella review of systematic reviews and meta-analyses.

INTRODUCTION: Laparoscopic surgery has been adopted in some parts of the world as an innovative approach to the resection of gastric cancers. However, in the modern era of surgical oncology, to overcome intrinsic limitations of the traditional laparoscopy, the robotic approach is advocated as able to facilitate the lymph node dissection and complex reconstruction after gastrectomy, to assure oncologic safety also in advanced gastric cancer patients. Previous meta-analyses highlighted a lower complication rate as well as bleeding in the robotic approach group when compared with the laparoscopic one. This potential benefit must be balanced against an increased time of intervention. The aim of this umbrella review is to provide a comprehensive overview of the literature for surgeons and policymakers in order to evaluate the potential benefits and harms of robotic gastrectomy (RG) compared with the laparoscopic approach for gastric cancer. METHODS AND ANALYSIS: We will perform a comprehensive search of the PubMed, Cochrane and Embase databases for all articles published up to May 2019 and reference list of relevant publications for systematic review and meta-analyses comparing the outcomes of RG and laparoscopic gastrectomy in patients with gastric cancer. Studies will be selected by two independent reviewers based on prespecified eligibility criteria and the quality will be assessed according to AMSTAR (A MeaSurement Tool to Assess systematic Reviews) checklist. All information will be collected using piloted and standardised data-extraction forms in DistillerSR developed following the Joanna Briggs Institute's recommended extraction items. ETHICS AND DISSEMINATION: This umbrella review will inform clinical and policy decisions regarding the benefits and harms of RG for treating gastric cancer. The results will be disseminated through a peer-reviewed publication, conference presentations and the popular press. Formal ethical approval is not required as primary data will not be collected.

From digital world to real life: a robotic approach to the esophagogastric junction with a 3D printed model.

BACKGROUND: Three-dimensional (3D) printing may represent a useful tool to provide, in surgery, a good representation of surgical scenario before surgery, particularly in complex cases. Recently, such a technology has been utilized to plan operative interventions in spinal, neuronal, and cardiac surgeries, but few data are available in the literature about their role in the upper gastrointestinal surgery. The feasibility of this technology has been described in a single case of gastroesophageal reflux disease with complex anatomy due to a markedly tortuous descending aorta. METHODS: A 65-year-old Caucasian woman was referred to our Department complaining heartburn and pyrosis. A chest computed tomography evidenced a tortuous thoracic aorta and consequent compression of the esophagus between the vessel and left atrium. A "dysphagia aortica" has been diagnosed. Thus, surgical treatment of anti-reflux surgery with separation of the distal esophagus from the aorta was planned. To define the strict relationship between the esophagus and the mediastinal organs, a life-size 3D printed model of the esophagus including the proximal stomach, the thoracic aorta and diaphragmatic crus, based on the patient's CT scan, was manufactured. RESULTS: The robotic procedure was performed with the da Vinci Surgical System and lasted 175 min. The surgeons had navigational guidance during the procedure since they could consult the 3D electronically superimposed processed images, in a "picture-in-picture" mode, over the surgical field displayed on the monitor as well as on the robotic headset. There was no injury to the surrounding organs and, most importantly, the patient had an uncomplicated postoperative course. CONCLUSIONS: The present clinical report highlights the feasibility, utility and clinical effects of 3D printing technology for preoperative planning and intraoperative guidance in surgery, including the esophagogastric field. However, the lack of published data requires more evidence to assess the effectiveness and safety of this novel surgical-applied printing technology.

Flavonoid mixture (diosmin, troxerutin, rutin, hesperidin, quercetin) in the treatment of I-III degree hemorroidal disease: a double-blind multicenter prospective comparative study.

PURPOSE: We evaluated the efficacy of new flavonoids mixture (diosmin, troxerutin, rutin, hesperidin, quercetin) to reduce bleeding from I-III degrees hemorrhoidal disease in the short and medium time. METHODS: One hundred fifty-four consecutive patients with hemorrhoidal disease recruited in four colorectal units were enrolled to the study. Exclusion criteria were allergy to the flavonoids, inflammatory bowel disease, obstructed defecation syndrome, pregnancy and puerperium, associated anal disease or hemorrhoidal thrombosis, proctologic surgical procedures within 1 year before recruitment, contemporary cancer or HIV, previous pelvic radiotherapy, patients receiving oral anticoagulant therapy, or contemporary administration of other therapy for hemorrhoids. Patients with inability to understand the study or mental disorders were also excluded. RESULTS: Seventy-eight were randomized to receive the mixture of diosmin, troxerutin, rutin, hesperidin, and quercetin (study group, SG), and 76 a mixture of diosmin in combination with hesperidin, diosmetin, isoroifolin, and linarin in purified micronized fraction (control group, CG). Bleeding, number of pathological piles, and Golligher's grade were assessed at each scheduled visit and compared using the Chi-square test. During the study period, bleeding improved after 1 and 6 months both in the SG (79.5 and 70.5%) and in the CG (80.2 and 75%) without significant differences between two groups. Satisfaction degree after 6 months was greater in the patients of the SG (4.05) towards the CG (3.25): this result was statistical significant (p 0.003). CONCLUSIONS: Use of flavonoids mixture (diosmin, troxerutin, rutin, hesperidin, quercetin) is a safe and effective mean of managing bleeding from hemorrhoidal disease and minimal adverse events are reported.

The treatment of breast cancer in one day surgery. A four year experience.

The number of short-stay surgery procedures has progressively increased since the concept of short-stay surgery was first introduced. Initially this type of surgery was reserved for patients undergoing inguinal hernia repair, proctological surgery, and various minor procedures. Careful patient selection makes it possible to apply one-day surgery to other surgical specialties including breast cancer surgery. Reducing the length of hospital stay lowers health care costs, and shortens waiting lists. The most important benefits for patients are a more rapid return to work and positive psychological effects. Exclusion criteria for one-day surgery are the lack of home care, excessive distance from place of treatment and the presence of any concomitant pathology that is a contraindication to this type of surgery. We report our experience in oncological surgery of the breast in one-day surgery.

Ileocecal-colonic intussusception caused by cecal adenocarcinoma A case report.

INTRODUCTION: Intussusception in adults is an infrequent cause of intestinal occlusion that is usually due to neoplasm lesions. The unspecific nature of the clinical presentation often delays diagnosis. It is most commonly emergency explorative laparotomy which clarifies the etiology of the occlusion. The authors report a case of intestinal occlusion caused by ileocecal-colonic invagination with a small cecal adenocarcinoma as lead point, in a 74-year-old woman. CASE REPORT: A 74-year-old woman came to the Emergency Department, complaining of crampy pain in the mid- and lower abdomen. An abdominal ultrasound revealed a "pseudokidney sign" apparently involving the cecum. Because there were no clear signs of occlusion, the patient was dicharged on the same day. Three days later, upon admission, the patient complained of episodes of abdominal pain with intervals of moderate well-being, associated with nausea, vomiting and an inability to pass stool (but not gas) for 36 hours. On clinical examination her abdomen was distended and tender on palpation in all quadrants, especially in the right iliac fossa where a large mass could be felt. Standard abdominal x-Ray documented gaseous distension of some loops of the jejunum-ileum with some air-fluid level. The patient underwent an abdominal CT scan which showed advanced intussusception that appeared to be ileocolic and multiple enlarged lymphnodes were found in the invaginated mesentery at the base of which there appears to be a thickening of the intestinal wall that is probably neoplastic in nature. The patient underwent explorative laparotomy. Ileocecal-colonic intussusception caused by a cecal growth 5 cm in diameter was found on examination of the surgical specimen. Histology showed that the cause of the large swelling of the ascending colon was a vegetating ulcerated adenocarcinoma (medium grade differentiation: G2), measuring 6.5x 4.0 cm, arising from a tubulovillous adenoma infiltrating the submucosa. CONCLUSIONS: Most cases of intussusception are caused by structural lesions, a large percentage of which are malignant, especially in the colon. In our patient the lead point was a small cecal polyp which, together with the last loop of the ileum and the ileocecal valve, was pulled into the ascending colon. Although most cases of intussusception in adults are diagnosed at the operating table, noninvasive diagnostic tools like ultrasonography and CT scanning are very useful. Treatment in adults is usually surgical and involves en bloc resection of the lesion. Manual reduction of the intussusception is not advisable because of the risk of dissemination if the lead point is malignant. KEY WORDS: Cecal adenocarcinoma, Itestinal resection, Intussusception in adults.

[Transanal haemorridal dearterialisation: personal experience]. / Emorroidectomia con tecnica THD (transanal haemorroidal dearterialization) nostra esperienza.

Transanal haemorroidal dearterialisation (THD) is a nonexcisional surgical technique for the treatment of piles, consisting in the ligation of the distal branches of the superior rectal artery, resulting in a reduction of blood flow and decongestion of the haemorroidal plexus. THD for 2 degrees and 3 degrees degree haemorroids is highly effective and painless. There are few complications and the technique can be performed as a day case.

[Radiation proctitis: description of two cases refractory to pharmacological treatment]. / La proctite attinica: descrizione di due casi refrattari al trattamento farmacologico.

Radiation proctitis, is a relatively frequent complication resulting from the direct or collateral irradiation of the rectum in radiotherapy treatment for genito-urinary or anorectal malignancies. The main symptoms are diarrhoea, tenesmus, proctorrhagia, anal pain, mucorrhoea and faecal incontinence. The evolution of chronic radiation proctitis requires treatment for related anaemia, anal incontinence and micturition disorders. The approach and type of treatment depend on the severity of the symptoms and on the endoscopic aspect, in relation to the response to previous medical therapy performed. In our experience, endoscopic treatment is the best choice in the presence of ongoing bleeding and the possible development of severe anaemia. The surgical option is mandatory in patients at high risk of sepsis, requiring a faecal diversion constructed using the Hartmann technique. We report two cases, observed during the last two years, one treated with endoscopic bipolar coagulation and the other with a double urinary and faecal diversion.

[Treatment of liver metastases from colorectal carcinoma: our experience]. / Trattamento delle metastasi epatiche da carcinoma colorettale: nostra esperienza.

The latest hepatic surgical strategies enable liver resections to be performed on a larger number of patients, improving the survival rate. Moreover, the contribution of radiological techniques and chemotherapy to surgery has led to the multidisciplinary management of patients suffering from liver metastases, involving surgeons, radiologists and oncologists. If surgical treatment is not considered curative, it is appropriate to advise alternative strategies in order to down-stage the disease and make it resectable.

[Stapled transanal rectal resection (STARR) in the treatment of rectocele: personal experience]. / La S.T.A.R.R. nel trattamento del rettocele. Esperienza personale.

Rectocele is an organic cause of chronic constipation, with a prevalence ranging from 8.95% to 12% in Europe and United States. Necessarily, the approach for rectocele repair is a surgical operation. Stapled transanal rectal resection (STARR) is safe and effective in the treatment of obstructed defecation syndrome. The authors' experience suggests that the surgical operation needs to be combined to rehabilitation exercises, before and after the surgical treatment, in order to strengthen the muscles of the pelvic pavement. From January 2005 to January 2007, 20 patients with outlet obstruction underwent STARR. Patients were selected for operation based on a strict diagnostic protocol: anamnesis, clinical examination, coloproctological and urogynaecological examinations, defecography, anorectal manometry, transrectal ultrasonography and peritoneal electromyography. The therapeutic protocol consists of 3 parts: phase I: rehabilitation of the pelvic pavement; phase II: surgical operation; III phase: post-surgical rehabilitation of the pelvic pavement; The clinical result was classified into: excellent (6 patients), when all constipation symptoms disappeared, good (11 patients), when patient has 1 or 2 obstructed defecation episodes treated with a laxative, fairly good (2 patients), more than 2 episodes, and poor (1 patient), when surgical operation doesn't improve any of the symptoms. Our results, confirmed by the literature, suggest that Longo's technique should be considered as gold standard for rectocele treatment.

[Urachus' carcinoma: a case report]. / Carcinoma dell'uraco. Case report.

Urachus' carcinoma represents a rare oncologic disease with an unfavourable prognosis due to the usual delay of correct diagnosis for its anatomical localization. Its surgical treatment varies from radical cystectomy to segmentary resection of the bladder with pelvic lymphadenectomy. We report a case occurred in a ninety years old female, in which the diagnosis was achieved only at laparotomy. The patient was submitted to surgery with the only generic diagnosis of "lower abdominal mass", and treated with segmentary resection.

[Management of patients with non-functioning gastroentero-pancreatic neuroendocrine tumours]. / Management di un paziente portatore di neoplasia neuroendocrina non fiunzionante del tratto gastro-entero-pancreatico (GEP).

The Authors examine the feasibility of diagnosing non-functioning gastroentero-pancreatic neuroendocrine tumours preoperatively or intraoperatively, with particular reference to laboratory examinations and octreoscan scintigraphy, which are capable of conditioning the surgical treatment and subsequent follow-up. Of the 4 cases reported here: three presented multiple intestinal localizations, and in only one case the origin of the primitive carcinoma was undefined. The suspicion of a non-functioning neuroendocrine tumour must be considered when yellowish or ochre-coloured intestinal lesions are found intraoperatively. Determination of specific markers and octreoscan scintigraphy must be performed without awaiting histological confirmation. Surgery plays a fundamental role in the debulking of these carcinomas. However, medical therapy with the aid of specific laboratory examinations and octreoscan scintigraphy may improve the long-term survival.
