  • Background/Aims: Few studies have compared the performances of endoscopic knives. This study aimed to compare the therapeutic outcomes of a novel core knife and the conventional IT knife 2 for endoscopic submucosal dissection (ESD) of gastric mucosal lesions. Methods: This prospective, non-inferiority trial included patients diagnosed with gastric adenoma or early-stage adenocarcinoma at Keimyung University Dongsan Hospital between June and November 2020. The patients were randomly assigned to either the core knife or the IT knife 2 group. The operators and assistants scored the knives' grip convenience and cutting abilities. Results: A total of 39 patients were enrolled (core knife group, 20 patients; IT knife 2 group, 19 patients). There were no significant between-group differences in operator-assessed grip convenience (9.600 vs. 9.526, p=0.753), cutting ability (9.600 vs. 9.105, p=0.158), or assistant-assessed grip convenience (9.500 vs. 9.368, p=0.574). Conclusions: The core knife achieved therapeutic outcomes that were comparable to those of the IT knife 2 for ESD of gastric mucosal lesions.

  • Background/Aims: Endoscopic wound suturing is an important factor that affects the ability to remove large and full-thickness lesions during endoscopic resection. We aimed to evaluate the effect of a traction metal clip with a fishhook-like device on wound sutures after endoscopic resection. Methods: From July 2020 to April 2021, patients who met the enrollment criteria were treated with a fishhook-like device during the operation to suture the postoperative wound (group A). Patients with similar conditions and similar size wounds who were treated with a "purse-string suture" to suture the wounds were retrospectively analyzed as the control group (group B). Difference in the suture rate, adverse events, time required for suturing, and number of metal clips were compared between the two groups. Results: The time required for suturing was 7.72±0.51 minutes in group A and 11.50±0.91 minutes in group B. This difference was statistically significant (F=13.071, p=0.001). The number of metal clamps used in group A averaged 8.1 pieces/case, and the number of metal clamps used in group B averaged 7.3 pieces/case. This difference was not statistically significant (F=0.971, p=0.331). Conclusions: The traction metal clip with the fishhook-like device is ingeniously designed and easy to operate. It has a good suture effect on the wound after endoscopic submucosal dissection and effectively prevents postoperative adverse events.

  • Backgrounds/Aims: Pancreaticoduodenectomy is the most common procedure for the management of duodenal pathologies. However, it is associated with substantial morbidity and a low risk of mortality. Pancreas-preserving limited duodenal resection (PPLDR) can be performed under specific scenarios. We share our experience with PPLDR and its outcome. Methods: We retrospectively analyzed a prospectively maintained database of patients undergoing limited duodenal resection in the form of wedge (sleeve) resection or segmental resection of one or more duodenal segments from March 2016 to March 2021 at a tertiary care center in North India. Results: During the study period, 10 patients (including 9 males) underwent PPLDR. Five of these 10 patients showed primary duodenal or proximal jejunal pathology, while the remaining five had duodenal pathology involving an adjacent organ tumor. Four patients underwent wedge (sleeve) resection, while the remaining six underwent segmental duodenal resection of one or more duodenal segments. Mean hospital stay was 6 days (range, 3-11 days) without 30-day mortality. Morbidity occurred in 4 patients (Grade I-II, n = 3; Grade III, n = 1). All patients were alive and disease-free at the time of last follow-up. The mean follow-up duration was 23 months (range, 2-48 months). Conclusions: PPLDR is a safe and effective alternative for pancreaticoduodenectomy when selected carefully for specific tumor types and location.
