RESUMEN
BACKGROUND: Evidence on the efficacy of minimally invasive (MI) segmental resection of splenic flexure cancer (SFC) is not available, mostly due to the rarity of this tumor. This study aimed to determine the survival outcomes of MI and open treatment, and to investigate whether MI is noninferior to open procedure regarding short-term outcomes. METHODS: This nationwide retrospective cohort study included all consecutive SFC segmental resections performed in 30 referral centers between 2006 and 2016. The primary endpoint assessing efficacy was the overall survival (OS). The secondary endpoints included cancer-specific mortality (CSM), recurrence rate (RR), short-term clinical outcomes (a composite of Clavien-Dindo > 2 complications and 30-day mortality), and pathological outcomes (a composite of lymph nodes removed â§12, and proximal and distal free resection margins length ⧠5 cm). For these composites, a 6% noninferiority margin was chosen based on clinical relevance estimate. RESULTS: A total of 606 patients underwent either an open (208, 34.3%) or a MI (398, 65.7%) SFC segmental resection. At univariable analysis, OS and CSM were improved in the MI group (log-rank test p = 0.004 and Gray's tests p = 0.004, respectively), while recurrences were comparable (Gray's tests p = 0.434). Cox multivariable analysis did not support that OS and CSM were better in the MI group (p = 0.109 and p = 0.163, respectively). Successful pathological outcome, observed in 53.2% of open and 58.3% of MI resections, supported noninferiority (difference 5.1%; 1-sided 95%CI - 4.7% to ∞). Successful short-term clinical outcome was documented in 93.3% of Open and 93.0% of MI procedures, and supported noninferiority as well (difference - 0.3%; 1-sided 95%CI - 5.0% to ∞). CONCLUSIONS: Among patients with SFC, the minimally invasive approach met the criterion for noninferiority for postoperative complications and pathological outcomes, and was found to provide results of OS, CSM, and RR comparable to those of open resection.

AIM: Operation time (OT) is a key operational factor influencing surgical outcomes. The present study aimed to analyse whether OT impacts on short-term outcomes of minimally-invasive right colectomies by assessing the role of surgical approach (robotic [RRC] or laparoscopic right colectomy [LRC]), and type of ileocolic anastomosis (i.e., intracorporal [IA] or extra-corporal anastomosis [EA]). METHODS: This was a retrospective analysis of the Minimally-invasivE surgery for oncological Right ColectomY (MERCY) Study Group database, which included adult patients with nonmetastatic right colon adenocarcinoma operated on by oncological RRC or LRC between January 2014 and December 2020. Univariate and multivariate analyses were used. RESULTS: The study sample was composed of 1549 patients who were divided into three groups according to the OT quartiles: (1) First quartile, <135 min (n = 386); (2) Second and third quartiles, 135-199 min (n = 731); and (3) Fourth quartile ≥200 min (n = 432). The majority (62.7%) were LRC-EA, followed by LRC-IA (24.3%), RRC-IA (11.1%), and RRC-EA (1.9%). Independent predictors of an OT ≥ 200 min included male gender, age, obesity, diabetes, use of indocyanine green fluorescence, and IA confection. An OT ≥ 200 min was significantly associated with an increased risk of postoperative noninfective complications (AOR: 1.56; 95% CI: 1.15-2.13; p = 0.004), whereas the surgical approach and the type of anastomosis had no impact on postoperative morbidity. CONCLUSION: Prolonged OT is independently associated with increased odds of postoperative noninfective complications in oncological minimally-invasive right colectomy.

PURPOSE: No evidences supporting or not the use of intra-abdominal drain (AD) in minimally invasive right colectomies have been published. This study aims to assess the outcomes on its use after robotic or laparoscopic right colectomies. METHODS: This is a multicenter propensity score matched study including patients who underwent minimally invasive right colectomy with (AD group) or without (no-AD group) the use of AD between February 1, 2007, and January 31, 2018. AD patients were matched to no-AD patients in a 1:1 ratio. Main outcomes were postoperative morbidity and mortality and anastomotic leak. RESULTS: A total of 653 patients were included. Of 149 (22.8%) no-AD patients, 124 could be matched. The rate of postoperative complications (AD n = 26, 21% vs. no-AD n = 26, 21%; p = 1.000), mortality (AD n = 2, 1.6% vs. no-AD n = 1, 0.8%; p = 1.000), anastomotic leak (AD n = 2, 1.6% vs. no-AD n = 5, 4.0%; p = 0.453), and wound infection (AD n = 9, 7.3% vs. no-AD n = 6, 4.8%; p = 0.581) did not significantly differ between the groups. Time to oral feeding was significantly shorter in the no-AD group [2 (1-3) vs. 3 (2-3), p = 0.0001]. The median length of hospital stay was 8 (IQR 7-9) in the AD group while it was 6 (IQR 5-9) in the no-AD group (p = 0.010). CONCLUSIONS: In conclusion, the use of AD after minimally invasive right colectomies has no influence on postoperative morbidity and mortality rates.

BACKGROUND: In literature, most of the comparative studies of robotic (RRC) versus laparoscopic (LRC) right colectomy are biased by the type of the anastomotic technique adopted. With this study, we aim to understand whether there is a role for robotics in performing right colectomies, comparing RRC versus LRC, both performed with intracorporeal anastomosis. METHODS: In this retrospective cohort study, all consecutive patients who underwent minimally invasive right colectomy (robotic or laparoscopic) with intracorporeal anastomosis in three Italian high-volume centers between February 1, 2007 and December 31, 2017 were included. Patients were grouped according to the method of surgery: RRC or LRC. RESULTS: A total of 389 patients were included in the study (305 RRC vs. 84 LRC). Patients' baseline characteristics were comparable between the groups. Operative time was significantly longer in RRC (250 min, IQR 209-305) group than LRC group (160 min, IQR 130-200) (p < 0.001). The median number of lymph nodes harvested was 22 (IQR 18-29) in RRC group while it was 19 (IQR 15-27) in LRC one (p = 0.028). No significant differences between the groups were seen in terms of time-to-first flatus, postoperative complications and length of hospital stay. Re-admission rate was significantly higher in LRC (n = 3, 3.6%) group than in RRC group (n = 1, 0.3%) (p = 0.033). CONCLUSIONS: In conclusion, RRC and LRC are comparable in terms of functional postoperative outcomes and length of hospital stay. RRC requires longer operative time, but the number of lymph nodes harvested may be higher.

BACKGROUND: The rapid adoption of robotic surgical systems across Europe has led to a critical gap in training and credentialing for gastrointestinal (GI) surgeons. Currently, there is no existing standardised curriculum to guide robotic training, assessment and certification for GI trainees. This manuscript describes the protocol to achieve a pan-European consensus on the essential components of a comprehensive training programme for GI robotic surgery through a five-stage process. METHODS AND ANALYSIS: In Stage 1, a Steering Committee, consisting of international experts, trainees and educationalists, has been established to lead and coordinate the consensus development process. In Stage 2, a systematic review of existing multi-specialty robotic training curricula will be performed to inform the formulation of key position statements. In Stage 3, a comprehensive survey will be disseminated across Europe to capture the current state of robotic training and identify potential challenges and opportunities for improvement. In Stage 4, an international panel of GI surgeons, trainees, and robotic theatre staff will participate in a three-round Delphi process, seeking ≥ 70% agreement on crucial aspects of the training curriculum. Industry and patient representatives will be involved as external advisors throughout this process. In Stage 5, the robotic training curriculum for GI trainees will be finalised in a dedicated consensus meeting, culminating in the production of an Explanation and Elaboration (E&E) document. REGISTRATION DETAILS: The study protocol has been registered on the Open Science Framework (https://osf.io/br87d/).

Primary and incisional ventral hernias are significant public health issues for their prevalence, variability of professional practices, and high costs associated with the treatment In 2019, the Board of Directors of the Italian Society for Endoscopic Surgery (SICE) promoted the development of new guidelines on the laparoscopic treatment of ventral hernias, according to the new national regulation. In 2022, the guideline was accepted by the government agency, and it was published, in Italian, on the SNLG website. Here, we report the adopted methodology and the guideline's recommendations, as established in its diffusion policy. This guideline is produced according to the methodology indicated by the SNGL and applying the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) methodology. Fifteen recommendations were produced as a result of 4 PICO questions. The level of recommendation was conditional for 12 of them and conditional to moderate for one. This guideline's strengths include relying on an extensive systematic review of the literature and applying a rigorous GRADE method. It also has several limitations. The literature on the topic is continuously and rapidly evolving; our results are based on findings that need constant re-appraisal. It is focused only on minimally invasive techniques and cannot consider broader issues (e.g., diagnostics, indication for surgery, pre-habilitation).

Laparoscopic ventral hernia repair (LVHR) is a widely practiced treatment for primary (PH) and incisional (IH) hernias, with acceptable outcomes. Prevention of recurrence is crucial and still highly debated. Purpose of this study was to evaluate predictive factors of recurrence following LVHR with intraperitoneal onlay mesh with a single type of mesh for both PH and IH. A retrospective, multicentre study of data collected from patients who underwent LVHR for PH and IH with an intraperitoneal monofilament polypropylene mesh from January 2014 to December 2018 at 8 referral centers was conducted, and statistical analysis for risk factors of recurrence and post-operative outcomes was performed. A total of 1018 patients were collected, with 665 cases of IH (65.3%) and 353 of PH (34.7%). IH patients were older (p < 0.001), less frequently obese (p = 0.031), at higher ASA class (p < 0.001) and presented more frequently with large, swiss cheese type and border site defects (p < 0.001), compared to PH patients. Operative time and hospital stay were longer for IH (p < 0.001), but intraoperative and early post-operative complications and reinterventions were comparable. IH group presented at major risk of recurrence than PH (6.7% vs 0.9%, p < 0.001) and application of absorbable tacks resulted a significative predictive factor for recurrence increasing the risk by 2.94 (95% CI 1.18-7.31). LVHR with a light-weight polypropylene mesh has low intra- and post-operative complications and is appropriate for both IH and PH. Non absorbable tacks and mixed fixation system seem to be preferable to absorbable tacks alone.

BACKGROUND AND OBJECTIVES: Although several large studies regarding patients undergoing minimally invasive repair of incisional hernia are currently available, the results are not particularly reliable as they are based on heterogeneous groups, different surgical techniques, different mesh types, or with a too short follow period. METHODS: We conducted a retrospective observational trial, collecting data from patients who underwent laparoscopic repair of a primary abdominal wall or an incisional hernia using the laparoscopic Intraperitoneal Onlay Mesh technique and a single mesh type, i.e., a composite polyester mesh with a hydrophilic film (Parietex CompositeTM mesh - Medtronic, Minneapolis, MN - USA). All patients signed an informed consent. RESULTS: One thousand seven hundred seventy-seven patients were enrolled. The median surgery time was 50 minutes and the median length of hospital stay was 2 days. Intraoperative complications occurred in 12 patients (0.7%), while early postoperative surgical complications occurred in 115 (6.5%); during follow-up, bulging mesh was diagnosed in 4.5% of cases and hernia recurred in 4.3% of patients. An overlap equal or greater than 4 cm resulted as a significant protective factor, while the use of absorbable fixing devices was a risk factor for recurrence (odds ration: 9.06, p < 0.001, 95% confidence interval: 4.19 - 19.57). CONCLUSIONS: Minimally invasive treatment of primary and postincisional abdominal wall hernias is a safe, effective, and reproducible procedure. An overlap equal or greater than 4 cm, the use of nonabsorbable fixing devices and a postoperative care and follow-up regime are crucial in order to obtain good results and low recurrence rates.

The robotic platform is becoming a multidisciplinary tool, versatile, and suitable for multiple procedures. Combined multivisceral resections may represent an alternative to sequential procedures with a potential favorable impact on postoperative morbidity, and on the timing of administration of adjuvant chemotherapy. We herein present our initial experience with full robotic multivisceral resections, and a review of the literature available. Between January 2018 and April 2020, 11 patients underwent multivisceral full robotic abdominal surgery: 4 patients presented with two synchronous tumors, 4 with primary cancer associated with a benign condition and 3 cases involved deep infiltrating endometriosis. Surgical teams enrolled were: General Surgery, Urology and Gynecology. A systematic bibliographic research up to April 2020 was conducted in PubMed. 4 colorectal resections combined with partial or radical nephrectomy were performed, as well as 2 right colectomies in combination with right adrenalectomy and gastric banding removal, 2 radical prostatectomies with Nissen Fundoplication and abdominal wall hernia repair, and 3 resections of deep pelvic endometriosis with colorectal involvement. Mean total operative time was 367 min. No intraoperative complication or conversion to open was registered. Overall postoperative complication rate was 18.2%. 26 papers were included in the review (10 case series and 16 case reports) with a total of 156 combined multivisceral robotic procedures recorded. Robotic combined multivisceral resections proved to be safe and feasible when performed in high volume centers by expert surgeons. The heterogeneity of reports does not allow for a standardization of the procedure. Further studies and accumulation of experience are needed.

Background: Robotic adrenalectomy offers several clinical benefits if compared with laparoscopic adrenalectomy; however, its superiority is still under debate. The aim of this study was the investigation of differences between the two techniques, and a comparison when approaching right or left side adrenal lesions was further conducted. Materials and Methods: All patients undergoing laparoscopic and robotic unilateral adrenalectomy at our institution from January 2006 to December 2019 were collected and retrospectively analyzed. Statistical analysis was conducted; differences between the two cohorts were reported. Results: A total of 160 cases were included (84 patients in laparoscopic adrenalectomy-group [LA-g] 76 cases in robotic adrenalectomy-group [RA-g]). The groups were homogeneous for demographic data. No intraoperative complications were reported; mean amount of intraoperative blood loss was comparable. No cases of conversion to open surgery were required. RA-g presented a longer operative time than LA-g for right adrenalectomy (P = .05), no differences were noted for left side (P = .187). Overall morbidity was 21% for LA-g and 10.5% for RA-g (P = .087), with an inferior rate of surgical complications for RA-g (P = .024), and for robotic left adrenalectomy than robotic right procedure (P = .03). Length of hospital stay was shorter for RA-g (P = .005). Conclusions: Robotic adrenalectomy presents similar outcomes as laparoscopic approach with some benefits for selected cases. Left adrenal lesions seem to receive greater advantages from robotic technique. Large randomized controlled trials are required to determine the role of robotic adrenal surgery and if the indication can be standardized based on the laterality of adrenal procedure.

INTRODUCTION: Most Human taeniasis are asymptomatic or associated with vague clinical manifestations, but cases of unusual migration of these parasites have been described. PRESENTATION OF A CASE: A case of challenging diagnosis of human Taenia Saginata infection is here presented: during COVID-19 pandemic we performed a mininvasive robotic subtotal gastrectomy for gastric angulus adenocarcinoma. 10 h after the end of the operation the patient presented an episode of vomiting with expulsion of a 5-meter-long adult form of Taenia Saginata. DISCUSSION: Parasitic infections are more frequent in the developing countries; in our case the transposition of small intestinal loop surely promoted the migration of Taenia Saginata through the gastro-jejunal anastomosis into the gastric stump.Preoperative evaluation (history, physical examination and imaging features) led to gastric cancer diagnosis and hindered the recognition of the taeniasis because of similar clinical presentations and the need to start quickly a therapeutic oncological strategy. CONCLUSION: Even if these cases are exceptional especially in Western Europe, it is important to obtain a detail clinical history and exclude parasitic infection as a cause of loss of weight and gastrointesinal abnormalities.
RESUMEN
BACKGROUND: Nowadays the robotic platform is widespread in general surgery, urology, and gynecology. Combined surgery may represent an alternative to sequential procedures and it allows the treatment, at the same time, of coexisting lesions; in this perspective, full-robotic multiorgan surgery is starting to gain interest from surgeons worldwide. METHODS: Between April and June 2019, two patients presenting with synchronous colorectal and kidney cancers underwent, respectively, full-robotic right colectomy with right partial nephrectomy and anterior rectal resection with left partial nephrectomy. Surgeries were performed by both the general surgery and urology team. RESULTS: No intraoperative complications were registered and the postoperative course was uneventful in both cases. CONCLUSIONS: Combined multiple organ surgery with full robotic technique is safe and offers oncological adequate results. A multi-team surgical pre-planning is mandatory to reduce invasiveness and operative time. To the best of our knowledge, these are the first reports of full robotic partial nephrectomy combined with colorectal procedures.

INTRODUCTION: Ingestion of a toothpick, both accidentally and intentionally, is a rare event. PRESENTATION OF CASE: We present the case of a 42-years old man who was admitted to the emergency department at our Institution presenting with a 5-days history of right sided abdominal pain. Laboratory blood count reported leukocytosis and alteration of principal inflammation index; at the abdominal ultrasound no signs of perforation or collection were described. DISCUSSION: Indication to surgery was posed and an explorative laparoscopy was performed. The presence of local peritonitis at the right colonic flexure secondary to a full thickness bowel perforation caused by a toothpick was found. There was also an acute phlegmonous appendicitis. A laparoscopic appendectomy and a full-thickness double running suture of the perforation were performed. CONCLUSION: Awareness about dangers of ingested toothpicks needs to be taken and the intestinal track/trace of the toothpick is mandatory until its expulsion.
RESUMEN
BACKGROUND: In the past 20 years, the fast spread of new surgical technologies has reached an important peak with the advent of the robotic surgery. Many studies have been run about a cosmetic desire to avoid neck scars after thyroid surgery and this has led to the development of remote access robotic thyroidectomy (RT). Among the various RT approaches, unilateral transaxillary access is one of the most widely used, reporting excellent results in terms of feasibility and patient's compliance. The mini-invasive technique demonstrated many potential shortcoming overcomes with the robotic approach. At our institution a team of 3 skilled endocrine surgeons with experience in laparoscopic and robotic procedures performed RT. Our aim is to report our 8-year single-centre robot-assisted thyroidectomy experience, by applying a gasless unilateral transaxillary approach with the so-called hybrid technique, and to demonstrate its safety and feasibility. METHODS: In the period between September 2010 and June 2018 at our institution, a total of 472 patients underwent thyroid and parathyroid transaxillary surgery. The hybrid technique was applied for all the robotic procedures. A total of 412 procedures were performed with the use of external "Modena Retractor" (CEATEC® Medizintechnik) and with 3 surgeons. According to international guidelines, our indications for robotic surgery were benign lesions with a diameter <5 cm, Graves' disease, well-differentiated thyroid cancers, and parathyroid adenomas. RESULTS: In this series, a total of 449 cases were registered. General data of patients were analyzed: gender, age, body mass index, tumor size, preoperative fine-needle aspiration examination, definitive histological examination, operative time, and postoperative complications. CONCLUSIONS: This study confirms the application of robotic approach in thyroid surgery as a feasible technique in terms of safety and complications risk. The hybrid technique, together with a dedicated surgical team, can lead to obtaining the same outcomes of traditional anterior cervicotomic surgery, adding a scarless thyroidectomy.

INTRODUCTION: Stump appendicitis is a rare but important complication that can occour after an open or laparoscopic appendectomy. Although it represents a recognized serious condition that should not be overlooked, it is not often considered by surgeons within the differential diagnoses faced with a patient presenting right iliac fossa abdominal pain, particularly those who present a previous history of appendectomy. MATERIAL OF STUDY: A comprehensive review of English literature was performed and 87 cases of stump appendicitis were identified. Each case was charted based on 10 variables and data were analyzed. One original case of stump appendicitis after open appendectomy treated at our institution is also described and taken as a model. DISCUSSION: Several factors may contribute to the etiology of stump appendicitis, mainly related to the length of the residual tissue after appendectomy. A delay in diagnosis, possibly misled by a previous history of appendectomy, represents a risk of complications and possible stump perforation. The imaging studies, especially CT scan, seem to be helpful tools in getting the earliest possible diagnosis. CONCLUSION: Surgeons should be aware of the occurrence of this rare but dangerous entity, in order to avoid a delay in diagnosis and in the appropriate therapeutic choice. We want to emphasize also the technical recommendations to be respected in course of appendectomy. KEY WORDS: Appendectomy, Appendicular residue, Diagnosis, Stump appendicitis.
