A systematic review and meta-analysis were conducted, including 22 studies. Both fixed-effect and random-effect models were applied to analyze nine outcomes evaluated.

Carbon-ion radiotherapy (CIRT) has emerged as a promising treatment modality for PDAC owing to its superior physical and radiobiological properties. However, a major challenge in this treatment is the proximity of the pancreas to radiosensitive organs including the stomach and duodenum, which limits dose escalation and increases the risk of severe complications, including ulceration and perforation. Herein, we report our experience with laparoscopic omentopexy as a spacer technique before CIRT in patients with locally advanced PDAC. A 55-year-old female with locally advanced PDAC, secondary to unreconstructible superior mesenteric vein involvement, who had planned to undergo CIRT. After 28 cycles of modified FOLFIRINOX, the tumor size demonstrated slight shrinkage. However, the tumor abutted the posterior wall of the stomach, raising concerns about ensuring a sufficient safety margin while delivering a curative dose of CIRT. Therefore, laparoscopic omentopexy was performed for spacer implantation between the pancreas and stomach. The patient was discharged on the postoperative day 2 without any complications. One month after the omentopexy, the patient completed all 12 fractions of the CIRT with no acute complications, except for grade 1 fatigue.

However, a major drawback of this approach is the high recurrence rate within six months post-radical surgery, which undermines the benefits of the extensive procedure; notably, most recurrences are distant, highlighting the efficacy of systemic therapy.

Improved outcomes have been reported in patients undergoing reoperation after 4 to 14 weeks following the initial cholecystectomy compared to immediate reoperation.
