Comparison of endoscopic ultrasound-guided drainage and percutaneous catheter drainage of postoperative fluid collection after pancreaticoduodenectomy.

Backgrounds/aims: Postoperative fluid collection is a common complication of pancreatic resection without clear management guidelines. This study aimed to compare outcomes of endoscopic ultrasound (EUS)-guided trans-gastric drainage and percutaneous catheter drainage (PCD) in patients who experienced this adverse event after pancreaticoduodenectomy (PD).

Methods: Demographic and clinical data and intervention outcomes of 53 patients who underwent drainage procedure (EUS-guided, n = 32; PCD, n = 21) for fluid collection after PD between January 2015 and June 2019 in our tertiary referral center were retrospectively analyzed.

The feasibility of robotic left-side hepatectomy with comparison of laparoscopic and open approach: Consecutive series of single surgeon.

Background: Recent studies report safety and effectiveness of robotic hepatectomy. In present study, we describe our initial experiences with robotic hepatectomy, focusing on left-side procedures.

Methods: A retrospective review was conducted of 13, 10, and 11 consecutive patients who underwent robotic, laparoscopic, and open left-side hepatectomy by the single surgeon.

Clinicopathologic Characteristics and Optimal Surgical Treatment of Duodenal Gastrointestinal Stromal Tumor.

Background: The clinicopathologic characteristics of duodenal gastrointestinal stromal tumor (GIST) were unclear and the optimal surgical procedure for duodenal GIST remains poorly defined. We aimed to analyze clinicopathological characteristics, survival outcomes based on the surgical procedure, and recommend optimal surgical treatment for duodenal GIST.

Methods: From July 2000 to April 2017, 118 patients with localized duodenal GIST underwent curative surgical resection at a single institution.

Effect of reoperation on long-term outcome of pT1b/T2 gallbladder carcinoma after initial laparoscopic cholecystectomy.

Background: A small proportion of gallbladder carcinomas (GBC) are incidentally detected after laparoscopic cholecystectomy (LC). This study intended to analyze the effect of extended reoperation on the long-term outcome of patients with pT1b/T2 GBC who had initially undergone LC.

Methods: A cohort of 203 patients who underwent R0 resection and whose pathology was pT1b or pT2 GBC was divided into 3 groups: open surgery (group I, n = 150), LC only (group II, n = 25), and initial LC and subsequent reoperation (group III, n = 28).

Prognosis of patients with pT1b/T2 gallbladder carcinoma who have undergone laparoscopic cholecystectomy as an initial operation.

Backgrounds/aims: Laparoscopic cholecystectomy (LC) has become a standard procedure for treatment of benign gallbladder diseases. There has been a small proportion of gallbladder cancer (GBC) which was incidentally found in the gallbladder specimen, and LC has been tried in some patients with faintly suspected GBC. This study intended to analyze the prognosis of patients with pT1b/T2 GBC who have undergone LC and the outcome of extended re-operation.
