Modified Single-Incision Plus One-Port Versus Conventional Five-Port Laparoscopic Pancreaticoduodenectomy for Nonpancreatic Periampullary Adenocarcinomas

August 2, 2026 updated by: Nanfang Hospital, Southern Medical University

Modified "Single-Incision Plus One "Versus Conventional "Five-Port" Laparoscopic Pancreaticoduodenectomy for Nonpancreatic Periampullary Adenocarcinomas: Study Protocol for A Multicentre Randomised Controlled Trial

This multicenter, randomized, controlled, non-inferiority trial will compare modified single-incision plus one-port laparoscopic pancreaticoduodenectomy (mSILPD+1) with conventional five-port laparoscopic pancreaticoduodenectomy (CLPD) in adults with histologically confirmed or highly suspected non-pancreatic periampullary carcinoma who are candidates for pancreaticoduodenectomy. A total of 232 participants will be randomly assigned in a 1:1 ratio. Outcome assessors who adjudicate complications and interpret imaging will be masked to treatment assignment. The primary outcomes are all-cause mortality within 90 days after surgery and overall survival at 1 year after surgery. Secondary outcomes will assess postoperative complications, surgical performance, postoperative recovery, disease-free survival, quality of life, and health-care costs.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Age 18 years or older and younger than 75 years.
  • Histopathologically confirmed non-pancreatic periampullary carcinoma, or a high clinical suspicion of non-pancreatic periampullary carcinoma when preoperative pathological confirmation is unavailable.
  • Determined by preoperative multidisciplinary team evaluation to require pancreaticoduodenectomy.
  • Able to understand and comply with study procedures.
  • Able and willing to provide written informed consent before any study-specific screening procedure.
  • Expected to benefit from therapeutic pancreaticoduodenectomy according to applicable clinical guidelines.

Exclusion Criteria:

  • Distant metastasis, including peritoneal, hepatic, distant lymph node, or other organ metastasis.
  • Requirement for distal, central, or total pancreatectomy, or another palliative procedure.
  • Preoperative American Society of Anesthesiologists physical status classification of 4 or higher.
  • Concurrent malignancy other than the target cancer.
  • Pregnancy or breastfeeding.
  • Severe psychiatric disorder that would interfere with study participation.
  • Receipt of neoadjuvant chemotherapy or radiotherapy before surgery.
  • Vascular invasion requiring vascular resection, as determined by the multidisciplinary team based on preoperative abdominal imaging.
  • Body mass index greater than 35 kg/m².
  • Participation in another clinical trial within the previous 3 months.

Procedure: Modified Single Incision plus one-port Laparoscopic Pancreaticoduodenectomy
A pancreaticoduodenectomy performed through a 60- to 80-mm periumbilical single-incision access platform containing three trocars, with one additional 12-mm laparoscopic port. Resection and reconstruction are performed according to the standardized multicenter operative protocol.
Other Names:
