When Gastroplasty Is Not Feasible in Ivor Lewis Esophagectomy: A Single-Center Study of Intrathoracic Esophagojejunostomy.

Objective: The surgical management of tumors of the esophagogastric junction is increasingly performed by minimally invasive Ivor Lewis esophagectomy. However, gastroplasty is not always feasible. The creation of a long loop is an alternative for esophageal reconstruction. The aim of this study was to evaluate the technical feasibility of using a minimally invasive thoracoscopic approach in esophagojejunostomy and to describe the contraindications for gastroplasty. Methods: All patients who had intrathoracic esophagojejunostomy in our center were identified in our database. Since 2016, the preferred approach for intrathoracic esophagojejunostomy is minimally invasive laparoscopy and thoracoscopy, using a long Roux-en-Y jejunal loop with a semimechanical triangular anastomosis technique. Results: Between January 1, 2012 and January 1, 2022, 12 patients who had esophagojejunostomy in our center were included in the study. Among them, 6 had thoracotomy and 6 had total minimally invasive thoracoscopy, representing 3.5% of surgical procedures for esophagogastric junction tumors since 2016. The mean operative time was 416.9 ± 107.47 minutes. No anastomotic leakage was observed in the minimally invasive group versus 2 leakages in the thoracotomy group. The main complication was pneumonia in 3 patients (27.3%). Finally, the main indication for intrathoracic esophagojejunostomy was tumor size with a mean of 4.72 ± 2.35 cm and the patient's surgical history. Conclusion: A total minimally invasive approach using a long jejunal loop with triangular anastomosis could be a feasible and reproducible alternative to gastroplasty to restore continuity in Ivor Lewis esophagectomy when the stomach cannot be used.

Can the Realization of an External Wirsungostomy be an Option for High-Risk Pancreatic Anastomosis After Pancreaticoduodenectomy?

BACKGROUND: Clinically relevant postoperative pancreatic fistula (POPF) occurs in 15-20% of patients after pancreaticoduodenectomy (PD) and reintervention in the setting of Grade C POPF remains associated with a mortality rate of up to 25%. In patients at high risk of POPF, PD with external wirsungostomy (EW) could be a safe alternative that avoids pancreatico-enteric anastomosis while preserving the remnant pancreas. METHODS: Of the 155 consecutive patients who underwent PD from November 2015 to December 2020, 10 patients were managed using an EW, all with a fistula risk score (FRS) ≥ 7 and BMI ≥30 kg/m2, and/or major associated abdominal surgery. The pancreatic duct was cannulated with a polyethylene tube to allow good external drainage of the pancreatic fluid. We retrospectively analyzed postoperative complications and endocrine and exocrine insufficiencies. RESULTS: The median alternative FRS was 36.9% [22.1-45.2]. There was no postoperative death. The 90-day overall severe complication (grade ≥3) rate was 30% (n = 3 patients), no patient required reoperation, and 2 hospital readmissions occurred. 3 patients experienced Grade B POPF (30%), managed using image-guided drainage for 2 patients. The external pancreatic drain was removed after a median drainage time of 75 days [63-80]. Two patients presented with late symptoms (> 6 months) warranting interventional management (pancreaticojejunostomy and transgastric drainage). Six patients experienced significant weight loss (> 2 kg) 3 months after surgery. One year after surgery, 4 patients still complained of diarrhea and were treated with transit-delaying drugs. One patient presented new-onset diabetes one year after surgery, and 1 of the 4 patients with preexisting diabetes experienced worsening disease. CONCLUSION: EW after PD might be a solution to reduce post-operative mortality following PD in high-risk patients.

Methodological and ethical quality of surgical trials from 2016 to 2020.

PURPOSE: Randomized controlled trials (RCTs) are the gold standard tool used to evaluate therapeutic interventions. The published results showed that progress still needs to be made not only from a methodological point of view but also from an ethical point of view. The aim of this study was to evaluate the methodological and ethical qualities of randomized clinical trials in surgery over the last few years. METHODS: All of the articles chosen for review reported on randomized controlled surgical trials and were published in 10 international journals between 2016 and 2020. Eligible studies were identified, selected, and then evaluated based on a broad set of predetermined criteria. Methodological quality was evaluated using the Jadad scale, and ethical quality was evaluated using the Berdeu score. RESULTS: The methodological quality score (Jadad scale) ranged from 5 to 13, with a mean of 10.0 ± 1.54. The methodological quality was insufficient (score ≤ 9) for 162 trials (31.2%). The ethical quality score ranged from 0.25 to 1, with a mean of 0.8 ± 0.11. Fifty-two articles (10%) did not state that informed consent was requested from the participants, and 21 articles (4%) did not report either research ethics committee or institutional committee protocol approval. CONCLUSION: The randomized clinical surgical trials analyzed showed that they had satisfactory methods in only 70% of the cases and that they had respected the fundamental ethical principles in 90% of the cases. However, less than 8% of the studies reported planned interim analysis, prospectively defined stopping rules, and independent monitoring committee.

Influence of Probiotics Administration Before Liver Resection in Patients with Liver Disease: A Randomized Controlled Trial.

BACKGROUND: By inhibiting the growth of pathogenic bacteria and modulating the local intestinal immune system, probiotics may reduce bacterial translocation and systemic endotoxaemia, factors partially responsible for post-operative complications following liver resection for hepatocellular carcinoma in patients with cirrhosis. METHODS: Patients with resectable hepatocellular carcinoma developed in the setting of chronic liver disease were prospectively divided into two equal-sized groups: one receiving probiotic treatment 14 days prior to surgery and the other receiving placebo. The primary endpoint was the level of circulating endotoxins after hepatectomy. Secondary endpoints were systemic inflammation (inflammatory cytokine levels), post-operative liver function and overall post-operative complication rate. RESULTS: From May 2013 to December 2018, 64 patients were randomized, and 54 patients were included in the analysis, 27 in each arm. No significant change in endotoxin levels was observed over time in either group (P = 0.299). No difference between the groups in terms of post-operative liver function and overall complication rates was observed. The only differences observed were significant increases in the levels of TNFalpha (P = 0.019) and interleukin 1-b (P = 0.028) in the probiotic group in the post-operative period. CONCLUSION: Contrary to the modest data reported in the literature, the administration of probiotics before minor liver resection for hepatocellular carcinoma developed in the setting of compensated chronic liver disease does not seem to have an impact on circulating endotoxin levels or post-operative complication rates. TRIAL REGISTRATION: Trial registration: NCT02021253.

Total Pelvic Exenteration, Cytoreductive Surgery, and Hyperthermic Intraperitoneal Chemotherapy for Rectal Cancer with Associate Peritoneal Metastases: Surgical Strategies to Optimize Safety.

BACKGROUND: Cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) is a curative treatment option for patients with peritoneal carcinomatosis. Total pelvic exenteration (TPE) is an established treatment option for locally advanced pelvic malignancy. These two procedures have high mortality and morbidity, and therefore, their combination is not currently recommended. Herein, we reported our experience on TPE associated with CRS/HIPEC with a critical analysis for rectal cancer with associate peritoneal metastases. METHODS: From March 2006 to August 2020, 319 patients underwent a CRS/HIPEC in our hospital. Among them, 16 (12 men and four women) underwent an associated TPE. The primary endpoints were perioperative morbidity and mortality. RESULTS: There was locally recurrent rectal cancer in nine cases, six locally advanced primary rectal cancer, and a recurrent appendiceal adenocarcinoma. The median Peritoneal Cancer Index (PCI) was 8. (4-16). Mean duration of the surgical procedure was 596 min (420-840). Complete cytoreduction (CC0) was achieved in all patients, while clear resection (R0) margins on the resected pelvic organs were achieved in 81.2% of cases. The median hospital stay was 46 days (26-129), and nine patients (56.2%) experienced severe complications (grade III to V) that led to death in two cases (12.5%). The total reoperation rate for patients was 6/16 (37.5%) and 3/16 (18.75%) with percutaneous radiological-guided drainage. CONCLUSIONS: In summary, TPE/extended TPE (ETPE) associated with CRS/HIPEC may be a reasonable procedure in selected patients at expert centers. Pelvic involvement should not be considered a definitive contraindication for CRS/HIPEC in patients with resectable peritoneal surface diseases if a R0 resection could be achieved on all sites. However, the morbidity and the mortality are high with this combination of treatment, and further research is needed to assess the oncologic benefit and quality of life before such a radical approach can be recommended.
