The CHOLEGAS study: multicentric randomized, blinded, controlled trial of gastrectomy plus prophylactic cholecystectomy versus gastrectomy only, in adults submitted to Gastric cancer surgery with curative intent

<p>Abstract</p> <p>Background</p> <p>The incidence of gallstones and gallbladder sludge is known to be higher in patients after gastrectomy than in general population. This higher incidence is probably related to surgical dissection of the vagus nerve branches and the anatomical gastrointestinal reconstruction. Therefore, some surgeons perform routine concomitant cholecystectomy during standard surgery for gastric malignancies. However, not all the patients who are diagnosed to have cholelithiasis after gastric cancer surgery will develop symptoms or require additional surgical treatments and a standard laparoscopic cholecystectomy is feasible even in those patients who underwent previous gastric surgery. At the present, no randomized study has been published and the decision of gallbladder management is left to each surgeon preference.</p> <p>Design</p> <p>The study is a randomized controlled investigation. The study will be performed in the General and Oncologic Surgery, Department of Oncology – Azienda Ospedaliero-Universitaria Careggi – Florence – Italy, a large teaching institution, with the participation of all surgeons who accept to be involved in, together with other Italian Surgical Centers, on behalf of the GIRCG (Italian Research Group for Gastric Cancer).</p> <p>The patients will be randomized into two groups: in the first group the patient will be submitted to prophylactic cholecystectomy during standard surgery for curable gastric cancer (subtotal or total gastrectomy), while in the second group he/she will be submitted to standard gastric surgery only.</p> <p>Trial Registration</p> <p>ClinicalTrials.gov ID.

The Cholegas trial: long-term results of prophylactic cholecystectomy during gastrectomy for cancer-a randomized-controlled trial

The incidence of cholelithiasis has been shown to be higher for patients after gastrectomy than for the general population, due to vagal branch damage and gastrointestinal reconstruction. The aim of this trial was to evaluate the need for routine concomitant prophylactic cholecystectomy (PC) during gastrectomy for cancer

The Cholegas trial: long-term results of prophylactic cholecystectomy during gastrectomy for cancer\u2014a randomized-controlled trial

Background: The incidence of cholelithiasis has been shown to be higher for patients after gastrectomy than for the general population, due to vagal branch damage and gastrointestinal reconstruction. The aim of this trial was to evaluate the need for routine concomitant prophylactic cholecystectomy (PC) during gastrectomy for cancer. Methods: A multicenter, randomized, controlled trial was conducted between November 2008 and March 2017. Of the total 130 included patients, 65 underwent PC and 65 underwent standard gastric surgery only for curable cancers. The primary endpoint was cholelithiasis-free survival after gastrectomy for gastric adenocarcinoma. Cholelithiasis was detected by ultrasound exam. Results: After a median follow-up of 62 months, eight patients (12.3%) in the control group developed biliary abnormalities (four cases of gallbladder calculi and four cases of biliary sludge), with only three (4.6%) being clinically relevant (two cholecystectomies needed, one acute pancreatitis). One patient in the PC group had asymptomatic biliary dilatation during sonography after surgery. The cholelithiasis-free survival did not show statistical significance between the two groups (P = 0.267). The number needed to treat with PC to avoid reoperation for cholelithiasis was 1:32.5. Conclusions: Concomitant PC during gastric surgery for malignancies, although reducing the absolute number of biliary abnormalities, has no significant impact on the natural course of patients

Naso-gastric or naso-jejunal decompression after partial distal gastrectomy for gastric cancer. Final results of a multicenter prospective randomized trial

Abstract BACKGROUND: Only a few, small, monocentric randomized controlled trials (RCTs) have compared routine vs. no placement of a nasogastric or nasojejunal tube decompression (NG/NJT) in patients undergoing partial distal gastrectomy (PDG) for gastric cancer. However, to our knowledge, no multicenter prospective RCT has analyzed the role of decompression after both the Billroth II (BII) procedure and Roux-en-Y (RY) gastrojejunostomy. The aim of this study was to determine whether NG/NJT prevents the consequences of postoperative ileus after PDG for gastric cancer after both BII reconstruction and RY. METHODS: Two hundred seventy patients undergoing PDG for gastric cancer were randomly assigned NG/NJT placement (NG/NJT group) or not (no-NG/NJT group) with either Billroth II gastrojejunostomy or Roux-en-Y gastrojejunostomy. The patients were monitored for postoperative complications, mortality, and postoperative course. RESULTS: By January 2010 to June 2012, among 270 patients undergoing PDG for gastric cancer, 134 were randomly assigned to NG/NJT placement (NG/NJT group) and 136 to no decompression (no-NG/NJT group). Time to passage of flatus was significantly shorter in the NG/NJT group than in the no-NG/NJT group, but only after RY reconstruction (3.3 \ub1 1.5 vs. 4.3 \ub1 1.6 days, P < 0.001, respectively). Postoperative abdominal distention was significantly lower in the NG/NJT group than in the no-NG/NJT group after both BII and the RY procedure (P < 0.001). No significant differences in postoperative mortality or morbidity, especially anastomotic leakage or intra-abdominal sepsis, were observed between the groups. CONCLUSION: Routine placement of an NG/NJT after BII and RY PDG is not necessary in elective surgery for gastric cancer

The Cholegas Study: safety of prophylactic cholecystectomy during gastrectomy for cancer: preliminary results of a multicentric randomized clinical trial

Abstract BACKGROUND: Cholelithiasis is more frequent in patients after gastrectomy, due to dissection of vagal branches and gastrointestinal reconstruction. METHODS: A randomized controlled trial was conducted from November 2008 to March 2012. Patients were randomized into two groups: prophylactic cholecystectomy (PC) and standard gastric surgery only (SS) for curable cancers. We planned three end points: evaluation of the number of patients who developed symptoms and needed further surgery for cholelithiasis after standard gastric cancer surgery, evaluation of the incidence of cholelithiasis overall after standard gastric cancer surgery and perioperative complications or costs of prophylactic cholecystectomy. The present study answers to the last end point only. RESULTS: After 40 months from the beginning of study, 172 patients were eligible from 9 Centers. Ten patients refused consent and 32 were excluded due to flawing of inclusion criteria (not confirmed adenocarcinomas and no R0 surgery). Therefore, final analysis included 130 patients: 65 in PC group and 65 in SS. Among PC group, 12 patients had surgical complications during the perioperative period; only 1 biliary leakage, conservatively treated, might have been caused by prophylactic cholecystectomy. 6 patients had surgical complications in SS group. One postoperative death occurred in PC group due to pulmonary embolism. Differences were not statistically significant. Similarly, no differences were significant in duration of surgery, blood loss, hospital stay. CONCLUSIONS: Concomitant cholecystectomy during standard surgery for gastric malignancies seemed to add no extra perioperative morbidity, mortality and costs to the sample included in the study
