Background: The Glissonean approach has been widely validated for both open and minimally invasive anatomic liver resection (MIALR). However, the possible advantages compared to the conventional hilar approach are still under debate. The aim of this systematic review was to evaluate the application of the Glissonean approach in MIALR., Methods: A systematic review of the literature was conducted on PubMed and Ichushi databases. Articles written in English or Japanese were included. From 2,390 English manuscripts evaluated by title and abstract, 43 were included. Additionally, 23 out of 463 Japanese manuscripts were selected. Duplicates were removed, including the most recent manuscript., Results: The Glissonean approach is reported for both major and minor MIALR. The 1st, 2nd and 3rd order divisions of both right and left portal pedicles can be reached following defined anatomical landmarks. Compared to the conventional hilar approach, the Glissonean approach is associated with shorter operative time, lower blood loss, and better peri-operative outcomes., Conclusions: Glissonean approach is safe and feasible for MIALR with several reported advantages compared to the conventional hilar approach. Clear knowledge of Laennec's capsule anatomy is necessary and serves as a guide for the dissection. However, the best surgical approach to be performed depends on surgeon experience and patients' characteristics. Standardization of the Glissonean approach for MIALR is important., (© 2021 Japanese Society of Hepato-Biliary-Pancreatic Surgery.)

Background: The Brisbane 2000 Terminology for Liver Anatomy and Resections, based on Couinaud's segments, did not address how to identify segmental borders and anatomic territories of less than one segment. Smaller anatomic resections including segmentectomies and subsegmentectomies, have not been well defined. The advent of minimally invasive liver resection has enhanced the possibilities of more precise resection due to a magnified view and reduced bleeding, and minimally invasive anatomic liver resection (MIALR) is becoming popular gradually. Therefore, there is a need for updating the Brisbane 2000 system, including anatomic segmentectomy or less. An online "Expert Consensus Meeting: Precision Anatomy for Minimally Invasive HBP Surgery (PAM-HBP Surgery Consensus)" was hosted on February 23, 2021., Methods: The Steering Committee invited 34 international experts from around the world. The Expert Committee (EC) selected 12 questions and two future research topics in the terminology session. The EC created seven tentative definitions and five recommendations based on the experts' opinions and the literature review performed by the Research Committee. Two Delphi Rounds finalized those definitions and recommendations., Results: This paper presents seven definitions and five recommendations regarding anatomic segmentectomy or less. In addition, two future research topics are discussed., Conclusions: The PAM-HBP Surgery Consensus has presented the Tokyo 2020 Terminology for Liver Anatomy and Resections. The terminology has added definitions of liver anatomy and resections that were not defined in the Brisbane 2000 system., (© 2021 Japanese Society of Hepato-Biliary-Pancreatic Surgery.)

Background: Although the number of minimally invasive liver resections (MILRs) has been steadily increasing in many institutions, minimally invasive anatomic liver resection (MIALR) remains a complicated procedure that has not been standardized. We present the results of a survey among expert liver surgeons as a benchmark for standardizing MIALR., Method: We administered this survey to 34 expert liver surgeons who routinely perform MIALR. The survey contained questions on personal experience with liver resection, inflow/outflow control methods, and identification techniques of intersegmental/sectional planes (IPs)., Results: All 34 participants completed the survey; 24 experts (70%) had more than 11 years of experience with MILR, and over 80% of experts had performed over 100 open resections and MILRs each. Regarding the methods used for laparoscopic or robotic anatomic resection, the Glissonean approach (GA) was a more frequent procedure than the hilar approach (HA). Although hepatic veins were considered essential landmarks, the exposure methods varied. The top three techniques that the experts recommended for identifying IPs were creating a demarcation line, indocyanine green negative staining method, and intraoperative ultrasound., Conclusion: Minimally invasive anatomic liver resection remains a challenging procedure; however, a certain degree of consensus exists among expert liver surgeons., (© 2021 Japanese Society of Hepato-Biliary-Pancreatic Surgery.)

Background: The concept of minimally invasive anatomic liver resection (MIALR) is gaining popularity. However, specific technical skills need to be acquired to safely perform MIALR. The "Expert Consensus Meeting: Precision Anatomy for Minimally Invasive HBP Surgery (PAM-HBP Surgery Consensus)" was developed as a special program during the 32nd meeting of the Japanese Society of Hepato-Biliary-Pancreatic Surgery (JSHBPS)., Methods: Thirty-four international experts gathered online for the consensus. A Research Committee performed a comprehensive literature review, classifying studies according to the Scottish Intercollegiate Guidelines Network method. Based on the literature review and experts' opinions, tentative recommendations were drafted and circulated among experts using online Delphi Rounds. Finally, formulated recommendations were presented online in the Expert Consensus Meeting of the JSHBPS on February 23rd, 2021. The final recommendations were validated and finalized by the 2nd Delphi Round in May 2021., Results: Seven clinical questions were selected, and 22 recommendations were formulated. All recommendations reached more than 85% consensus among experts at the final Delphi Round., Conclusions: The Expert Consensus Meeting for safely performing MIALR has presented a set of clinical guidelines based on available literature and experts' opinions. We expect these guidelines to have a favorable effect on the safe implementation and development of MIALR., (© 2021 Japanese Society of Hepato-Biliary-Pancreatic Surgery.)

Purpose: To analyze different types of management and one-year outcomes of anastomotic leakage (AL) after elective colorectal resection., Methods: All patients with anastomotic leakage after elective colorectal surgery with anastomosis (76/1,546; 4.9%), with the exclusion of cases with proximal diverting stoma, were followed-up for at least one year. Primary endpoints were as follows: composite outcome of one-year mortality and/or unplanned intensive care unit (ICU) admission and additional morbidity rates. Secondary endpoints were as follows: length of stay (LOS), one-year persistent stoma rate, and rate of return to intended oncologic therapy (RIOT)., Results: One-year mortality rate was 10.5% and unplanned ICU admission rate was 30.3%. Risk factors of the composite outcome included age (aOR = 1.08 per 1-year increase, p = 0.002) and anastomotic breakdown with end stoma at reoperation (aOR = 2.77, p = 0.007). Additional morbidity rate was 52.6%: risk factors included open versus laparoscopic reoperation (aOR = 4.38, p = 0.03) and ICU admission (aOR = 3.63, p = 0.05). Median (IQR) overall LOS was 20 days (14-26), higher in the subgroup of patients reoperated without stoma. At 1 year, a stoma persisted in 32.0% of patients, higher in the open (41.2%) versus laparoscopic (12.5%) reoperation group (p = 0.04). Only 4 out of 18 patients (22.2%) were able to RIOT., Conclusion: Mortality and/or unplanned ICU admission rates after AL are influenced by increasing age and by anastomotic breakdown at reoperation; additional morbidity rates are influenced by unplanned ICU admission and by laparoscopic approach to reoperation, the latter also reducing permanent stoma and failure to RIOT rates., Trial Registration: ClinicalTrials.gov # NCT03560180.

Background: Primary colic lymphoma represents a rare disease accounting for the 0.2%-0.6% of all large-bowel malignancies. We here report a case of diffuse large B-cell lymphoma presenting as a left colic stenosis in a patient who had undergo renal transplant 23 years before., Case Report: A 67-years old man presented with recurrent abdominal pain, distension, nausea and constipation since 3 weeks. His past medical history included hepatic and renal polykystose with renal transplant 23 years before. Colonoscopy revealed a non-surmountable inflammatory left colic stenosis at 55 cm from the anal verge. Biopsies demonstrated inflammatory colic mucosa without neoplastic cells. Non-enhanced CT scan and CT virtual colonoscopy were performed, showing a left colon circumferential thickening of 4 cm. Laparoscopic left colectomy was performed to treat the colic obstructive syndrome and to have complete specimen analysis. After Pathological analysis and Immunohistochemistry the diagnosis of diffuse large B cell lymphoma was established. The resection was R0. The postoperative course was uneventfully., Conclusion: Large B-cell lymphoma represents a rare case of bowel tumor. However it has to be considered in the differential diagnosis of colic stenosis in immunosuppressed patients as transplant recipients., Key Words: Colorectal lymphoma, Diffuse large B-cell lymphoma, Immunosuppressed patients.

Background: Video-assisted anal fistula treatment (VAAFT) is now a mature technique, supported by many short-term published case series., Methods: We designed a monocentric, retrospective and observational study in order to evaluate early and long-term outcomes of VAAFT in the treatment of primary and recurrent complex anal fistula. Between November 2011 and March 2014, 224 consecutive patients affected by complex perianal fistula underwent Video Assisted Anal Fistula Treatment. Fifty-two were affected by primary and 172 by recurrent disease. We registered all intra and postoperative complications and healing rate. Median follow-up was 48 months (range 27-60 months)., Results: In the primary fistula group, 40 of the 52 patients were completely healed within 3 months after surgery (77%); at 12 months, considering also 12 patients (23%) treated with a second VAAFT due to recurrent disease, the overall healing rate was 92.3% In the second group with recurrent anal fistula (N.=172), primary healing was observed in 110 patients (64%; P=0.1) within 3 months after surgery and increases to 80.2%, after 12 months (P=0.06). Few patients required analgesics in the postoperative period (N.=33, 14.7%), the remaining did not require pain killers at all. All patients were able to resume daily activities within 7 days from surgery (range 2-12 days). Main limitation of our study was its retrospective and monocentric design., Conclusions: VAAFT seems to be a safe and effective technique for treating primary and recurrent perianal fistula, providing a very good healing rate without sphincters impairment and allowing a very quick return to normal activities.

Background: Laparoscopic liver surgery (LLS) gained popularity bringing several advantages including decreased morbidity and reduction of length of hospital stay compared to open., Methods: To understand practice and evolution of LLS in Belgium, a 20-questions survey was sent to all members of the Royal Belgian Society for Surgery, the Belgian Section of Hepato-Pancreatic and Biliary Surgery and the Belgian Group for Endoscopic Surgery., Results: Thirty-seven surgical units representing 61 surgeons performing LLS in Belgium responded: 50% from regional hospitals, 28% from university and 22% from peripheral hospitals. Replies from high volume centers (>50 liver-surgery/year) were 19%. More than 25% of liver procedures were performed laparoscopically in 35% of centers. LLS is adopted since more than 15-years in 14.5% of centers with an increasing rate reported in 59%. Low relevance of LLS in the hospital organization (26.5%) and lack of time in surgical schedules (12%) or of specific training (9%) are the main barriers for further diffusion. More than 80% of the responders agreed to participate to a national prospective registry., Conclusion: LLS is mainly performed in experienced HPB units with an increasing interest in peripheral centers. A prospective national registry will be useful by providing real data in terms of indications, morbidity and overall evolution.

Introduction: Hollows viscus injury (HVI) is a rare occurrence and represents a clinical challenge because of its subtle and nonspecific clinical findings. The specific aims of this study were to determine the overall frequency of HVI in blunt trauma patients occurring in large urban area, the relative frequency of various hollow organ injuries, and the outcomes of such injuries., Materials and Methods: A retrospective trauma registry review was performed by analysing data from the University Hospital Sant' Andrea in Rome and data from the Emergency Surgery and Trauma Care Unit of S. Filippo Neri Hospital in Rome The clinical records of all blunt abdominal trauma observed between January 2006 and December 2014 were blind analysed. Variables considered for analysis were: sex, age, time/type of trauma, associated injuries, timing/characteristics of operative treatment, ISS, AIS, length of hospital stay, morbidity and mortality., Results: Seventy-one, 7.5% of all abdominal trauma recorded, were coded having 89 HVI. The overall morbidity and mortality rates were 29.6% (n=21/71) and 19.7% (n=14/71) respectively. Multivariate analysis indicated that only WBC (p=0.007) was significant independent predictor of morbidity whereas preoperative transfusion (p=0.010) and ISS (p<0.001) were significant risk factors for mortality., Discussion: HVI is rarely found in patients with blunt abdominal trauma and it can be fatal and life-threatening, particularly in patients for whom a pertinent diagnosis is delayed., Conclusion: It appears clearly that during an ER evaluation of a blunt abdominal trauma an HIV has nowadays always to be considered to reach a quick diagnosis and prompt surgical intervention., Key Words: Emergency, Hollow Viscus Injury, Surgery, Trauma.

Purpose: The aim of the present study was to evaluate the clinical features, management and outcome of patients submitted to emergency surgery because of intestinal lymphoma., Methods: A consecutive series of fourteen patients with gastrointestinal tract lymphoma referred for emergency surgery between March 2006 and May 2010 was retrospectively analyzed., Results: Patients including 9 males (64.2%) and 5 females (35.7%). The mean age of male and female was 55.4 + 21.2 and 78.4 + 9.0 respectively. The difference was statistically significant (p <0.04). Ileum was the most common location (13 cases, 86.6%) and a small bowel resection was the commonest surgical procedure performed. Presence of etiological risk factor for developing intestinal lymphoma was detected in 6 patients (40%). The overall morbidity rate was 40.0% (6 patients) and the mortality rate was 53,3% (8 patients). The estimated 12, 24, and 36-months overall survival rate was 56%, 33%, and 22% respectively., Discussion: Our study reports an elevated overall mortality accounting for 8 patients which were all but two of advanced stage; 6 patients died in the postoperative course. Univariate and multivariate analysis failed to show significant differences maybe because the total number of subjects was too small to reach statistical significance. However the Odds Ratio was significantly high for the presence of etiological risk factor (OR 7.50) and perforation as presenting symptom (OR 6.67)., Conclusion: An aggressive surgical attitude comprising an ample ileum resection is needed in almost all cases because an acute presentation is closely related with an advanced stage of the disease and with a high risk for anastomotic disruption, both conditions leading to a poor short and long-term survival.

The aim of the present study was to assess the prognostic significance of thoracic and abdominal trauma in severely injured patients. A retrospective analysis was performed based on data from the period from March 1 2006 to December 31 2007, taken from the Trauma Registry of the University Hospital "SantAndrea" in Rome. A total of 844 trauma patients were entered in a database created for this purpose, and only patients with an Injury Severity Score (ISS) > 15, (163 patients, 19.3%), were selected for the present study. These patients were divided into 2 groups: Group A (103 patients, 63.2%), consisting of patients with at least one thoracic injury, and Group B (46 patients, 28.2%) consisting of patients with concomitant thoracic and abdominal injuries. The impact of thoracic and abdominal trauma was studied by analyzing mortality and morbidity, in relation to patient age, cause and dynamics of trauma, length of hospital stay, and both ISS and New ISS (NISS). In a vast majority of cases, the cause of trauma was a road accident (126 patients, 77.3%). The mean age of patients with ISS > 15 was 45.2 +/- 19.3 years. The mean ISS and NISS were 25.7 +/- 10.5 and of 31.4 +/- 13.1 respectively. The overall morbidity and mortality rates were 18.4% (30 patients) and 28.8% (47 patients) respectively. In Group A the mortality rate was 23.3% (24 patients) and the morbidity rate was 33.9% (35 patients). In Group B mortality and morbidity rates were 369% (17 patients) and 43.5% (20 patients) respectively. It was shown that the presence of both thoracic and abdominal injuries significantly increases the risk of mortality and morbidity. In patients with predominantly thoracic injuries, NISS proved to be the more reliable score, while ISS appeared to be more accurate in evaluating patients with injuries affecting more than one region of the body.

Abdominal trauma is present in 7-10% of all trauma victims, and in cases of severe trauma is often found together with orthopedic, thoracic or central nervous system (CNS) injuries. The aim of the present study was to perform a comparative analysis of abdominal trauma and trauma involving other body regions, evaluating the prognostic significance of abdominal injuries in patients with severe trauma, based on data from a multidisciplinary trauma registry. Data from the period from March 1 2006 to December 31 2007 was collected from the trauma registry of the University Hospital Sant'Andrea in Rome, Italy. There were 25.875 patients (31.4%) with the diagnosis of trauma out of a total of 82.293 patients admitted to the emergency department. Eight hundred forty-four patients were selected according to specific inclusion criteria and patients with abdominal injuries were further selected. The following data were investigated: patient age, the trauma mechanism, duration of recovery, Abbreviated Injury Scale (AIS), Injury Severity Score (ISS), type and the incidence of abdominal and extra-abdominal injuries. Morbidity and mortality, especially in patients with spleen and liver injuries, were analyzed. There were 79 patients (9.3%) with abdominal trauma. Their mean ISS was 25.7 +/- 14.3. Sixty-one (77.2%) of these patients had sustained severe trauma (ISS > 15). Forty-one patients (51.8%) underwent surgery. The overall mortality rate was 24.1%, 19 patients all with ISS > 15, so that the mortality rate for patients with severe trauma was 31.2%. Splenic trauma was the most frequent, and was found in 36 patients (45.6%) whose mean ISS was 31.1 +/- 144. Twenty-two patients (61.6%) were treated surgically; a total of 21 splenectomies and one laparoscopic procedure to control bleeding were performed. Overall mortality among patients with splenic trauma was 30.5% (11 patients), with an average spleen AIS of 3.3 +/- 0.8 (died vs. survived p = n.s.). Liver injuries were found in 33 patients (41.7%). The mean ISS was 28.4 +/- 11.6. Sixty-five percent of the patients were given nonsurgical treatment. Overall mortality among liver trauma patients was 24.2% (8 patients) with an average liver AIS of 3.2 +/- 0.3 (died vs. survived p < 0.05). In multivariate analysis, among the general population of trauma patients, the ISS (p < 0.001), patient age (p < 0.003), and an orthopedic (p < 0.002) or CNS injury (p < 0.006) proved to be significant independent predictors of the presence of an abdominal injury. Multivariate analysis showed that in patients with abdominal trauma, only the ISS (p < 0.001) was a significant independent predictor of mortality.

The aim of the present study was to identify risk factors for morbidity and mortality in patients submitted to emergency colonic surgery. Between 1997 and 2008 157 patients, 106 of whom affected by colon cancer (67.5%) and 51 by benign disease (32.5%), were treated. The risk factors for morbidity and mortality were evaluated by univariate and multivariate analysis considering clinical and demographic data. The overall 30-day morbidity and mortality rates were 19.1% (30 patients) and 12.7% (20 patients), respectively. Among patients affected by cancer the mortality rate was 15% (16 patients) and the morbidity rate 23.6% (25 patients), while among the patients with benign disease the mortality rate was 7.8% (4 patients) and the morbidity rate 9.8% (5 patients). No postoperative surgical complications were noted. The strongest risk factors for early death were postoperative medical complications such as cardiopulmonary, renal, thrombo-embolic and infectious complications. The results of the univariate analysis showed that advanced age, neoplastic disease, advanced stage of cancer and associated medical disease prior to surgery play a role as risk factors for morbidity and mortality. In the multivariate analysis only the presence of associated medical disease proved to be a significant independent predictor of outcome. Emergency surgery for both neoplastic and benign colonic disease is still associated with an increased risk of death. Although restorative colectomy should be regarded as the first choice procedure in the emergency setting, Hartmann's procedure is still widely used in high-risk patients.
