Pelvic Exenteration - Past, Present and Future.

Background: Bearing in mind that the open procedure is already validated by multiple studies, the article aims to prove that pelvic exenteration performed in a minimally invasive fashion might offer better survival and to potentially identify prognostic factors for the outcome of these patients. Material and Methods: Data regarding past and present classifications and surgical indications are presented. Patient data were collected retrospectively. Results: The most frequent diseases treated with pelvic exenteration, in terms of the hystological type, were gynecological malignancy and squamous cell carcinoma. Recurrent pelvic disease was found in 68.2% of patients. R0 resection was achieved in 72.7% of patients in the MI group, and in 73.7% of patients in the OP group. Peri-operative morbidity was reported to be 56.6% for open surgery, and 18.1% for minimally invasive. Average DFS was 20.15 months, ranging from 1.5 to 70.3 months, while the OS was calculated to be 38.1 months (0.33 1508) up until November 2023. Conclusion: Pelvic exenteration is a continuously improving surgical procedure, open approach being favored to minimally invasive one. On the other hand, hospitalization and morbidity are reduced when choosing the latter. R0 and lymph node status are important predictors for overall survival, as well as major early postoperative complications. All in all, pelvic exenteration is still a promising surgical procedure to extend cancer patients lives.

Robotic or laparoscopic pelvic exenteration for gynecological malignancies: feasible options to open surgery.

OBJECTIVE: To acknowledge that minimally invasive pelvic exenteration is a feasible alternative to open surgery and potentially identify prediction factors for patient outcome. METHODS: The study was designed as a retrospective single team analysis of 12 consecutive cases, set between January 2008 and January 2022. RESULTS: Six anterior and 6 total pelvic exenterations were performed. A 75% of cases were treated using a robotic approach. In 4 cases, an ileal conduit was used for urinary reconstruction. Mean operative time was 360±30.7 minutes. for anterior pelvic exenterations and 440±40.7 minutes. for total pelvic exenterations and mean blood loss was 350±35 mL. An R0 resection was performed in 9 cases (75%) and peri-operative morbidity was 16.6%, with no deaths recorded. Median disease-free survival was 12 months (10-14) and overall survival (OS) was 20 months (1-127). In terms of OS, 50% of patients were still alive 24 months after surgery. Taking into consideration the follow up period,16.6% of females under 50 or above 70 years old did not reach the cut off and 4 out of 6 patients that failed to reach it were diagnosed with distant metastases or local recurrence (p=0.169). CONCLUSION: Our experience is very much consistent with literature in regard to primary site of cancer, post-operative complications, R0 resection and survival rates. On the other hand, minimally invasive approach and urinary reconstruction type were in contrast with cited publications. Minimally invasive pelvic exenteration is indeed a safe and feasible procedure, providing patients selection is appropriately performed.

Propensity Score-Matched Analysis of Minimal Invasive Surgery versus Open Surgery for Colorectal Cancer in Older Patients.

Introduction: Currently, surgeons deal with an older patient cohort, confronting new challenges brought by the raised life expectancy. This population is unrepresented in surgical trials; therefore, the optimal therapy is still a matter of debate. The efficacy of open versus minimal invasive management of colorectal cancer (CRC) in an elderly cohort is not clearly established. The current study assesses the minimal invasive approach in elderly patients undergoing colorectal surgery. Material and Methods: The General Surgery Department database was inquired between 2012 and 2015 using the following filters: age â?¥ 65 and rectal or colon adenocarcinoma. After applying the exclusion criteria, 975 cases were obtained: 842 underwent open surgery (OS) and 133 underwent minimal invasive surgery (MIS). A propensity score matching was performed to reduce patient selection bias. Results: After the propensity score matching, the MIS group had a shorter postoperative hospital stay than the OS group (p = 0.025). From the preoperative variables, the presence of chronic lung disease was significantly higher in the OS group (p = 0.039). The presence of chronic lung disease positively associates with the Clavien-Dindo classification (p 0.001) and with the number of days from surgery to discharge (p = 0.028). Conclusion: The chronological age alone should not be a limit to MIS granting that it showed no inferiority to the OS in terms of postoperative morbidity, correlating with lower postoperative stay in the elderly. Further prospective studies are needed to assess the outcome of MIS in elderly population.

Short-term Outcome of Robotic and Laparoscopic Surgery for Gynecological Malignancies: A Single-center Experience.

Objectives: Minimally invasive surgery (MIS) has become the preferred option for many gynecologic pathologies since complication rate and postoperative recovery time have decreased considerably. Postoperative complications remain an important aspect when using the MIS approach, if they are not timely or accurately diagnosed and treated. The main aim of the study is to first assess their incidence, followed by identifying possible risk factors. Furthermore, the secondary aim is to identify if the type of MIS approach used, robotic or laparoscopic, may render some additional benefits. Materials and Methods: The database of the General Surgery Department was queried between 2008 and 2019 for patients with gynecologic pathology: 2907 cases were identified. An additional selection was performed using the following filters: MIS and neoplasia. All emergency surgeries were excluded. One hundred and ninety-eight cases were obtained. Results: The majority of complications were urological (11.6%) with only 7.07% requiring a specific urological procedure. The second most common was lymphorrhea 4.5%. Dindo-Clavien classification correlates positively with the postoperative hospital stay (PHS) (P = 0.000), the type of surgery (P = 0.046), the primary tumor location (P = 0.011), conversion rate (P = 0.049), the expertise of the lead surgeon (P = 0.012), and the operative time (P = 0.002). The urological complications correlate positively with the type of surgery (P = 0.002), the tumor location (P = 0.001), early reintervention (P = 0.000), operative time (P = 0.006), postoperative hemorrhage (P = 0.000), pelvic abscess (P = 0.000), venous thrombosis (P = 0.011), and postoperative cardiac complications (P = 0.002). Laparoscopic and robotic approaches were comparatively assessed. The PHS (P = 0.025), the type of surgery performed (P = 0.000), and primary tumor location (P = 0.011) were statistically significantly different. Conclusion: Postoperative complications reported after MIS for gynecological malignancies show similar incidence as in the current literature, also taking into consideration those for the open approach. The robotic approach seems to be able to perform more complex surgeries with no difference in the postoperative complication rates. The expertise of the lead surgeon in gynecology correlates with lower postoperative complications. Further prospective studies are needed to confirm these results.

Achalasia Treatment. Robotic Approach or Laparoscopy?

Background: Nowadays the question persists whether to choose the endoscopic or surgical method as the first treatment of choice for achalasia. Another debate topic is about the differences between the outcomes of the two approaches of minimally invasive surgical treatment and their feasibility. Material and Methods: This retrospective observational study included 193 patients with achalasia treated between 2008 and 2021. The patients were divided into 2 groups (A and B): 152 with minimally invasive heller myotomy (HM), and 41 with pneumatic dilation (PD). Patients surgically treated were then subdivided into robotic group (RG) and laparoscopic group (LG). Results: The recurrence rate was significantly higher in PD group (Ã?2 = 16.81, DF = 1, p 0.0001), with a success rate of 63,4%, comparing with 92,7% in HM group. No significant difference was obtained between the 2 groups concerning symptom relief on patients successfully treated. The success rate was comparable between the robotic and laparoscopic groups (p = 1). Significant difference was obtained in length of hospital stay between the 2 groups, with a mean of 4.78 +-1.59 days in the RG and, respectively, 5.52 +-2.1 days in the LG (t = 2.40, DF = 124.34, p = 0.0177). Postprocedural esophagitis rates were higher in patients with no fundoplication (6 out of 37 - 16.2%) and in patients treated with pneumatic dilation (4 out of 26 - 15.4%) than in patients with fundoplication (4 out of 46 - 8.5%). Conclusion: The present study indicates that surgery may be a better choice in fit patients for the treatment of achalasia. The procedure has a better success rate, even if the long-term outcomes are comparable in patients successfully treated. The success rate and long-term results were comparable between laparoscopy and robotic surgery.

Is There a Role for Minimally Invasive Surgery in Cervical Cancer Treatment: Carry on, Discard, or Modify? A Literature Review and Case Series Presentation.

Oncological surgery is constantly evolving. Recommendations and guidelines are updated periodically in light of new research. Since surgery is a key step in the treatment of cervical cancer in Romania and considering the new findings, this study aims to assess the new guideline recommendations and the surgical treatment options available. The paradigm shift that took place in 2018 left the question: does minimally invasive surgery still play a role in the treatment of cervical cancer? K ouml;hler surgical technique seems to address some of the issues raised by the minimally invasive surgery with good results. H ouml;ckel proposes total mesometrial excision to decrease the risk of recurrence. This study presents 3 cases of cervical cancer patients with stages ranging from IB1 to IIIB that had undergone total mesometrial excision and vaginal cuff closure using the laparoscopic approach to minimize the risk of local recurrence. The case series presented showed that it is feasible and safe to merge these techniques. Further prospective studies are needed in order to assess the risk and benefits of these techniques.

Endoscopic Retrograde Cholangiopancreatography in Acute Biliary Pancreatitis: Urgent vs. Delayed and the Outcome of Same-Admission Cholecystectomy.

Introduction: Acute pancreatitis (AP) represents a major burden for the medical system, associating important morbidity and mortality rates. This paper is focused on debatable aspects of the management of biliary AP, namely indications, timing and outcomes of endoscopic retrograde cholangiopancreatography (ERCP) on the hand and, on the other hand, same-admission cholecystectomy as a preventive measure for recurrent disease. Material and methods: This is a retrospective study including 108 patients with biliary AP in whom ERCP was performed, treated in the Clinical Emergency Hospital of Bucharest between 2016 and 2020. According to the urgency of the ERCP, we divided the patients into two groups: urgent versus delayed ERCP. Results: Urgent ERCP was performed in 52 patients, while delayed ERCP was performed in 56 patients; the hospital stay was higher in the urgent group than in the delayed group (10 days vs 8 days, p = 0.299) with no difference in morbidity rates. The mean time between ERCP and surgery was 5 days, without significant difference between the groups. The laparoscopic approach was the preferred method, with a conversion rate of 7%. Conclusion: ERCP with stone extraction followed by same-admission laparoscopic cholecystectomy is a safe therapeutic option, that prevents recurrent pancreatitis. The timing of the procedures remains debatable, further prospective studies being needed to achieve statistical significance.

TNF-alpha releasing capacity of the whole blood drops after open total splenectomy, but increases after partial/subtotal or minimally invasive splenectomy.

BACKGROUND: The mechanisms that induce immunodeficiency after splenectomy remain unknown. The aim of this study was to measure the cytokine releasing capacity of the whole blood as an expression of the innate immunity after total (TS) and subtotal/partial splenectomy (S/PS) in order to assess the impact of splenectomy on the individual cytokine reactivity. METHODS: We prospectively collected blood before (D0) and at multiple time points after splenectomy (7 days - D7, 30 days - D30, 90 days - D90, 180 days - D180, and 360 days - D360) and measured the cytokines releasing capacity of IL-6, TNF-alpha and IL-10 from whole blood under LPS stimulation which we normalized to the monocytes number. RESULTS: When analyzing all splenectomies at D0, D7 and D30, normalized ΔTNF-alpha significantly dropped after splenectomy (p = .0038) and normalized ΔIL-6 and ΔIL-10 did not significantly change. More specifically, normalized ΔTNF-alpha dropped after TS (p = .0568) and significantly increased after S/PS (p = .0388). Open surgery induced a decrease in normalized ΔTNF-alpha (p = .0970), whereas minimally invasive (MI) surgery significantly increased the normalized ΔTNF-alpha releasing capacity (p = .0178). The cytokine levels were heterogenous between pathologies at D0, and ΔIL-6 dropped mainly in cirrhotic patients after splenectomy (all underwent TS), ΔTNF-alpha dropped in immune thrombocytopenic purpura patients (all underwent TS), but increased in spherocytosis (91% underwent S/PS) after splenectomy. CONCLUSIONS: Splenectomy induces a decrease of the pro-inflammatory cytokine TNF-alpha and if splenic parenchyma is spared and the surgery is performed MI, this change is hindered.

Abdominoperineal Resection for Rectal Cancer: Open, Laparoscopic or Robotic Approach.

OBJECTIVES: The present study compares abdominoperineal resection (APR) performed by minimally invasive and open approach, regarding preoperative selection criteria, intraoperative and early postoperative aspects, in choosing the suitable technique performed by surgical teams with experience in both open and minimally invasive surgery (MIS). Methods: This is a retrospective study, conducted between 2008-2020. Two hundred thirty-three patients with APR performed for low rectal or anal cancer were included. The cohort was divided into two groups, depending on the surgical approach used: Minimally Invasive Surgery (laparoscopic and robotic procedures) and Open Surgery (OS). The perioperative characteristics were analyzed in order to identify the optimal approach and a possible selection criteria. Results: We identified a high percentage of patients with a history of abdominal surgery in the open group (p = .0002). Intraoperative blood loss was significantly higher in the open group (p= .02), with an increased number of simultaneous resections (p = .041). The early postoperative outcome was marked by significantly lower morbidity in the MIS group (p = .005), with mortality recorded only in the open group (3 cases), in patients that associated severe comorbidities. The hystopathological results identified a significant number of patients with stage T2 in the MIS group (p= .037). Conclusions: Minimally invasive surgery provides a major advantage to APR, by avoiding an additional incision, the specimen being extracted through the perineal wound. The success of MIS APR seems to be assured by a good preoperative selection of the patients, alongside with experienced surgical teams in both open and minimally invasive rectal resections. The lack of conversion identified in robotic APR confirm the technical superiority over laparoscopic approach.

Pancreatic Fistula after D1+/D2 Radical Gastrectomy according to the Updated International Study Group of Pancreatic Surgery Criteria: Risk Factors and Clinical Consequences. Experience of Surgeons with High Caseloads in a Single Surgical Center in Eastern Europe.

PURPOSE: Incidence, risk factors, and clinical consequences of pancreatic fistula (POPF) after D1+/D2 radical gastrectomy have not been well investigated in Western patients, particularly those from Eastern Europe. MATERIALS AND METHODS: A total of 358 D1+/D2 radical gastrectomies were performed by surgeons with high caseloads in a single surgical center from 2002 to 2017. A retrospective analysis of data that were prospectively gathered in an electronic database was performed. POPF was defined and graded according to the International Study Group for Pancreatic Surgery (ISGPS) criteria. Uni- and multivariate analyses were performed to identify potential predictors of POPF. Additionally, the impact of POPF on early complications and long-term outcomes were investigated. RESULTS: POPF was observed in 20 patients (5.6%), according to the updated ISGPS grading system. Cardiovascular comorbidities emerged as the single independent predictor of POPF formation (risk ratio, 3.051; 95% confidence interval, 1.161-8.019; P=0.024). POPF occurrence was associated with statistically significant increased rates of postoperative hemorrhage requiring re-laparotomy (P=0.029), anastomotic leak (P=0.002), 90-day mortality (P=0.036), and prolonged hospital stay (P<0.001). The long-term survival of patients with gastric adenocarcinoma was not affected by POPF (P=0.661). CONCLUSIONS: In this large series of Eastern European patients, the clinically relevant rate of POPF after D1+/D2 radical gastrectomy was low. The presence of co-existing cardiovascular disease favored the occurrence of POPF and was associated with an increased risk of postoperative bleeding, anastomotic leak, 90-day mortality, and prolonged hospital stay. POPF was not found to affect the long-term survival of patients with gastric adenocarcinoma.

Laparoscopic Cholecystectomy in Cirrhotic Patients: A Retrospective Study.

Introduction: Cirrhosis is a leading cause of morbidity and mortality around the world. Although cirrhotic patients are considered to have a higher risk for surgical procedures than non-cirrhotic ones, there are certain pathologies such as gallstones cholecystitis that cannot be treated otherwise. The focus of this study is to evaluate the main characteristics of the patients with lithiasic cholecystitis and liver cirrhosis and to assess if there is a correlation between them and postoperative morbidity evaluated with Dindo-Clavien classification. Material and Methods: This is a retrospective study. The database from General Surgery Department of Fundeni Clinical Institute was queried between 2014-2018 using as key words "cirrhosis" and "cholecystitis". The initial interrogation reveled 57 cases out of which 3 were excluded since other resections were associated. Results: This study identified that Dindo-Clavien classification positively correlates with the open approach (0.405, p=0.002), emergency surgery (0.599, p=0.000), acute cholecystitis (0.476, p=0.000), high MELD score (0.291, p=0.008) and Child score (0.346, p=0.007) and furthermore with high levels of total bilirubin (0.220, p=0.047), high INR (0.286, p=0.010), the presence of ascites (0.303, p=0.022) and portal hypertension (0.266, p=0.044). It also correlates negatively with the levels of hemoglobin (-0.295, p=0.044). Conclusion: Adequate estimation of perioperative mortality and morbidity is generally limited by the retrospective nature of most studies and the patient's selection criteria. Emergency surgery, acute cholecystitis and the open approach carry the highest risk for unfavorable results of cholecystectomy in cirrhotic patients.

Minimal Access Surgery for the Treatment of Gastric Gastrointestinal Stromal Tumours - A Single Centre Experience.

Introduction: Laparoscopic techniques have been increasingly adopted in the field of General Surgery in the last decades. The main disadvantages of laparoscopy are related to limited degrees of freedom of instruments and poor ergonomics, which are associated with a steep learning curve. Robotic surgery overcomes most of the technical limitations of laparoscopic surgery and has the potential to expand the indications of minimal access surgery (MAS) in procedures that are difficult to perform using laparoscopy. Methods: Patients who underwent MAS resections of gastric gastrointestinal stromal tumours (GIST) between January 2002 and October 2018 in a single Surgical Department were retrospectively analysed. Demographic data as well as the following characteristics were recorded for each patient: age, sex, symptoms, tumour location and size, type of surgical procedure, intraoperative blood loss, operative time, length of hospital stay, histopathological assessment of resection margins, and incidence of perioperative complications. Results: The mean patient age was 58 (range, 27-81 years). Most lesions were found on the great curvature (7) and in the distal stomach or antrum (7), respectively. Twenty patients underwent laparoscopic resection, while five patients had robotic resection of gastric GISTs. Surgical laparoscopic treatment consisted of antrectomy (n=4) and wedge gastrectomy (n=16). In all robotic cases a wedge gastrectomy was performed. One patient was converted to open surgery due to adhesions from previous operation. The mean operative time was 130 minutes (range, 70-210 minutes).The mean tumour size was 3.8 cm (range, 2-7 cm). There were no complications except one case that required reoperation for postoperative bleeding. There were no mortalities. Conclusion: The MAS approach of gastric GISTs is safe and effective and it is associated with low morbidity. Therefore, it should constitute the first option in patients with small tumours and favourable locations. The only limiting factor for the widespread use of MAS resections for gastric GISTs is surgeon expertise in this challenging technique.

Transanal Total Mesorectal Excision - A Case Report.

Transanal total mesorectal excision (TaTME), first introduced in 2010, represents a relatively new approach in the surgical treatment of rectal cancer. A case of a 65-years-old patient diagnosed with moderately differentiated adenocarcinoma of the middle rectum (cT2N0M0) is presented. Taking into consideration patient's characteristics and tumour features, the surgical team decided to use transanal total mesorectal excision technique. The surgical technique, as well as potential postoperative complications and oncological issues are discussed in the article. Patient selection and extensive experience in minimally invasive colorectal surgery are the bases for an optimal technique implementation. Although further studies are required in order to confirm its superiority over the laparoscopic total mesorectal excision, TaTME seems to be a safe and feasible option in the surgical approach of rectal cancer.

Laparoscopic Hartmann s Reversal: A Single Center Experience.

Minimally invasive colorectal surgery showed multiple advantages in terms of morbidity, surgeons applied this approach to Hartmann reversal considering improving the reversal rate and postoperative outcome. The database from Fundeni Clinical Institute, General Surgery Department, was analyzed, selecting the laparoscopic Hartmann reversals. Nine cases were reported with a median age of 63 years, mean BMI 29 and three of them with prior open Hartmann surgery. The average operative time was 223 minutes, without any case necessitating ileostomy diversion. No anastomotic leakage was reported. The laparoscopic approach seems to be an attainable alternative in the reversal of Hartmann procedure, considering the experience of the surgical team and the patient's characteristics. Further studies are needed in order to confirm its superiority on larger case series.

The Outcome of Colorectal Surgery in Cirrhotic Patients: A Case Match Report.

Background: Colorectal surgery in cirrhotic patients has had limited indications, but as the study aims to show, careful evaluation of risk factors can extend boundaries. Methods: From January 2011 to January 2016, using a case match cohort, 68 patients with colorectal malignancy and cirrhosis were compared against 136 persons with no liver disease. Significant risk criteria, morbidity and mortality were evaluated. Results: When analyzing specific risk factors age, etiology and severity of liver disease (MELD, Child-Pugh score, ascites and hypoalbuminemia) were found to be significant to surgical outcome. Approach and type of intervention as well as emergency status reflected upon reintervention rates with 10.2% in the cirrhotic population vs 5.1% in the non-cirrhotic one (p=0.3). Postoperative morbidity was higher in the chronic liver disease patients - 47.1% vs 27.9% in the case-match group (p=0.035). Mortality rate in the cirrhotic population was 5.9% while in the non-cirrhotic one was 2.2% (p=0.2). Child C patients had a morbidity and a mortality rate of 75% and 50% respectively. CONCLUSION: Child A patients can be treated no different than the general population; Child B group needs proper assessment and care while in Child C population surgery should at all costs be avoided.
