Short- and long-term outcomes of laparoscopic radical gallbladder resection for gallbladder carcinoma: A multi-institutional retrospective study in Japan

BACKGROUND/PURPOSE

Laparoscopic resection of gallbladder carcinomas remains controversial. This study aimed to evaluate the surgical and oncological outcomes of laparoscopic procedures for suspected gallbladder carcinoma (GBC).

METHODS

In this retrospective study, data regarding suspected GBC treated with laparoscopic radical cholecystectomy before 2020 in Japan, was included. Patient characteristics, surgical procedure details, surgical outcomes, and long-term outcomes were analyzed.

RESULTS

Data of 129 patients with suspected GBC who underwent laparoscopic radical cholecystectomy were retrospectively collected from 11 institutions in Japan. Among them, 82 patients with pathological GBC were included in the study. Laparoscopic gallbladder bed resection was performed in 114 patients and laparoscopic resection of segments IVb and V was performed in 15 patients. The median operation time was 269 min (range: 83-725 min), and the median intraoperative blood loss was 30 mL (range: 0-950 mL). The conversion and postoperative complication rates were 8% and 2%, respectively. During the follow-up period, the 5-year overall survival rate was 79% and the 5-year disease-free survival rate was 87%. Recurrence was detected in the liver, lymph nodes, and other local tissues.

CONCLUSION

Laparoscopic radical cholecystectomy is a treatment option with potential favorable outcomes in selected patients with suspected GBC.

Retroperitoneal perforation arising from duodenal diverticulum treated by endoscopic drainage: a case report

Retroperitoneal perforation of duodenal diverticula around the papilla of Vater is relatively rare. In this report, we describe retroperitoneal abscess, which was successfully treated by endoscopic drainage. Thus, endoscopic approach for retroperitoneal perforation caused by diverticulum is one of the treatment options in addition to surgery.

Laparoscopic radical cholecystectomy with lymph node dissection for gallbladder carcinoma

BACKGROUND

Laparoscopic surgery has been widely employed in the field of digestive surgery, since the minimally invasive procedure provides a significant benefit to patients. However, laparoscopic curative surgery for gallbladder cancer has been rarely described. The aim of this study was to evaluate the effectiveness and validity of laparoscopic radical cholecystectomy with lymph node dissection (Lap-RC) to treat with T1b/T2 gallbladder carcinoma.

METHODS

A total of 11 patients underwent Lap-RC for gallbladder carcinoma from November 2001 until June 2013. While 4 patients were preoperatively diagnosed with T1b/T2 gallbladder carcinoma, 7 patients were diagnosed with incidental T1b/T2 gallbladder carcinoma by postoperative pathological examination after laparoscopic cholecystectomy. Common bile duct resection and biliary tract reconstruction were performed in 2 cases. End points in this clinical study were tumor recurrence and survival of patients.

RESULTS

Mean operative time was 196 min, and average hospital stay after surgery was 6.4 days, excluding 2 cases with biliary tract reconstruction. One patient died of recurrence of cancer 89 months after surgery, and another patient died of other reason with local recurrence 39 months after the operation. The other 9 patients were all alive without recurrence at this writing. The 5-year survival rate was 100 % for T1b patients and 83.3 % for T2. These results indicate that almost equivalent outcomes compared with open surgery in terms of curability were achieved.

CONCLUSIONS

We conclude that pure laparoscopic radical cholecystectomy with lymph node dissection is safe and beneficial for the patients with T1b/T2 gallbladder carcinoma.

[Case of histopathological findings of choriocarcinoma in stomach cancer]

A case of gastric cancer which contained a part of choriocarcinoma was reported in this study. The patient was a 64-year-old man, who was operated on with the diagnosis of gastric cancer in the prepyloric region. The postoperative histological examination revealed that typical choriocarcinoma was noted in a part of the adenocarcinoma, which occupied almost the entire portion of the surgical specimen. In addition, the precise localization of human chorionic gonadotropin (hCG) in the portion of choriocarcinoma was proved by the indirect immunoperoxidase stain (PAP method). The patient showed the gynecomastia clinically. The concentration of postoperative serum hCG was elevated and testicular abnormality was not noted clinically.
