Laparoscopic ventral rectopexy using the transanal vacuum test for complete rectal prolapse.

Laparoscopic ventral rectopexy was performed in 84 patients with complete rectal prolapse from January 2016 to December 2019. In the initial 27 cases, three cases had recurrence, especially in cases of a long rectal prolapse measuring over 10 cm. In order to avoid recurrence, the transanal vacuum test was performed following the dissection of the rectovaginal septum towards the pelvic floor.

Innovation in surgery/operating room driven by Internet of Things on medical devices.

Background: With the improvement of sensor technology, the trend of Internet of Things (IoT) is affecting the medical devices. The aim of this study is to verify whether it is possible to "visualize instrument usage in specific procedures" by automatically accumulating the digital data related to the behavior of surgical instruments/forceps in laparoscopic surgery.

Methods: Five board-certified surgeons (PGY 9-24 years) performed laparoscopic cholecystectomy on 35-kg porcine (n = 5).

Mucosal perforation during laparoscopic surgery for achalasia: impact of preoperative pneumatic balloon dilation.

Background: Controversy remains whether preoperative pneumatic balloon dilation (PBD) influences the surgical outcome of laparoscopic esophagocardiomyotomy in patients with esophageal achalasia. The aim of this study was to evaluate whether preoperative PBD represents a risk factor for surgical complications and affects the symptomatic and/or functional outcomes of laparoscopic Heller myotomy with Dor fundoplication (LHD).

Methods: A retrospective chart review was conducted on a prospectively compiled surgical database of 103 consecutive patients with esophageal achalasia who underwent LHD from November 1994 to September 2014.

[Bypass surgery or stent placement for biliary obstruction in patients with unresectable pancreatic cancer].

The therapeutic strategy for biliary obstruction in patients with unresectable pancreatic cancer is controversial. We compared complications and prognosis between 2 groups: the B group, 8 patients who were diagnosed as having inoperable pancreatic cancer at laparotomy and underwent bypass surgery, and the S group, 7 patients who underwent endoscopic stent placement for biliary obstruction due to clinically unresectable pancreatic cancer. Although 1 patient developed cholangitis and surgical site infection in the B group, there was no difference in the duration of hospital stay between the 2 groups.
