Functional outcomes of 100 patients with adenocarcinoma of the esophagogastric junction undergoing Cheng's GIRAFFE(®) reconstruction after proximal gastrectomy / 中华胃肠外科杂志

Objective: To investigate the functional outcomes and postoperative complications of Cheng's GIRAFFE reconstruction after proximal gastrectomy. Methods: A descriptive case series study was conducted. Clinical data of 100 patients with adenocarcinoma of the esophagogastric junction who underwent Cheng's GIRAFFE reconstruction after proximal gastrectomy in Cancer Hospital of University of Chinese Academy of Sciences (64 cases), Zhejiang Provincial Hospital of Chinese Medicine (24 cases), Lishui Central Hospital (10 cases), Huzhou Central Hospital (1 case) and Ningbo Lihuili Hospital (1 case) from September 2017 to June 2021 were retrospectively analyzed. Of 100 patients, 64 were males and 36 were females; the mean age was (61.3 ± 11.1) years and the BMI was (22.7±11.1) kg/m(2). For TNM stage, 68 patients were stage IA, 24 were stage IIA and 8 were stage IIB. Postoperative functional results and postoperative complications of radical gastrectomy with Giraffe reconstruction were analyzed and summarized. Gastroesophageal reflux disease questionnaire (RDQ) score and postoperative endoscopy were used to evaluate the occurrence of reflux esophagitis and its grade (grade N, grade A, grade B, grade C, and grade D from mild to severe reflux). The continuous data conforming to normal distribution were expressed as (mean ± standard deviation), and those with skewed distribution were presented as median (Q1, Q3). Results: All the 100 patients successfully completed R0 resection, including 77 patients undergoing laparoscopic surgery and 23 patients undergoing laparotomy. The Giraffe anastomosis time was (38.6±14.0) min; the blood loss was (73.0±18.4) ml; the postoperative hospital stay was 9.5 (8.2, 13.0) d; the hospitalization cost was (6.0±0.3) ten thousand yuan. Fourteen cases developed perioperative complications (14.0%), including 7 cases of pleural effusion or pneumonia, 3 cases of anastomotic leakage, 2 cases of gastric emptying disorder, 1 case of gastrointestinal hemorrhage and 1 case of anastomotic stenosis, who were all improved and discharged after symptomatic management. Patients were followed up for (33.3±1.6) months. Eight patients were found to have reflux symptoms by RDQ scale six months after surgery, and 11 patients (11/100,11.0%) were found to have reflux esophagitis by gastroscopy, including 6 in grade A, 3 in grade B, and 2 in grade C. All the patients could control their reflux symptoms with behavioral guidance or oral PPIs. Conclusion: Cheng's GIRAFFE reconstruction has good anti-reflux efficacy and gastric emptying function; it can be one of the choices of reconstruction methods after proximal gastrectomy.

Risk factors and prognosis for patients with residual tumor after radiofrequency ablation of hepatocellular carcinoma / 中华肿瘤杂志

<p><b>OBJECTIVE</b>To investigate the risk factors and prognosis of patients with residual tumor after radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC).</p><p><b>METHODS</b>The clinicopathological data of 114 patients with HCC undergoing RFA in our hospital from May 2000 to March 2007 were retrospectively studied, and the prognostic factors of residual tumor were analyzed.</p><p><b>RESULTS</b>After one session of RFA, 90 patients had complete ablation and 24 had residual tumor. The median overall survivals in the complete ablation group and residual tumor group were 40 and 29 months, respectively. There was no statistically significant difference between those two groups (P = 0.242). 24 patients with residual tumor were re-treated by RFA or hepatectomy or TACE. Among them 11 patients achieved complete response and 13 incomplete response, their median overall survival were 53 and 28 months, respectively. There was no significant difference between first complete ablation group and second complete response group (P = 0.658). However, compared with the first complete ablation group, the incomplete response group had poor prognosis (P = 0.012). Multivariate analysis showed that tumor size > 3 cm (P = 0.007) and proximity to a large vessel (P = 0.042) were independent risk factors for residual tumor after RFA.</p><p><b>CONCLUSION</b>Tumor size > 3 cm and proximity to a large vessel are independent risk factors for residual tumor after RFA. Further treatment of residual tumor is necessary to eliminate the tumor and improve prognosis.</p>

Prognostic factors and outcome in patients with intrahepatic recurrence after hepatectomy for hepatocellular carcinoma / 中华肿瘤杂志

<p><b>OBJECTIVE</b>To investigate the prognostic factors and treatment choice for intrahepatic recurrence after hepatectomy in patients with hepatocellular carcinoma (HCC).</p><p><b>METHODS</b>Clinicopathological data of 184 HCC patients with intrahepatic recurrence after hepatectomy were collected. The influences of twenty one clinicopathological factors and treatment modalities on the survival after recurrence were retrospectively analyzed.</p><p><b>RESULTS</b>Univariate analysis showed that preoperative serum alpha-fetoprotein (AFP) >100 ng/ml, microscopic venous invasion, patients classified as Child-Pugh class B or C at diagnosis of recurrence, multiple recurrence foci and early recurrence (< or =12 months) were poor prognostic factors. Cox multivariate analysis showed that Child-Pugh class at diagnosis of recurrence, number of recurrent foci and time to recurrence were independent risk factors for survival in patients with recurrence. Median survival after recurrence was 34 months, 23 months, 15 months and 9 months, respectively, in patients treated by repeated hepatectomy, local ablation therapy, transcatheter arterial chemoembolization (TACE) or non-treatment in 69 patients with solitary recurrence. There were statistically significant differences among these four groups (P < 0.05).</p><p><b>CONCLUSION</b>classification of Child-Pugh class A at the first time of diagnosis, solitary recurrence, late recurrence (> 12 months), and intrahepatic recurrence occurred after repeated hepatectomy or local ablation therapy are better prognostic factors in patients with HCC recurrence.</p>
