NCT05353426

Brief Summary

Visceral pain (VP) following laparoscopic sleeve gastrectomy remains a substantial problem. VP is associated with autonomic symptoms, especially nausea and vomiting, and is unresponsive to traditional pain management algorithms aimed at alleviating somatic (incisional) pain. The present study was performed to evaluate the safety and effectiveness of laparoscopic paragastric autonomic neural blockade (PG-ANB) in managing the symptoms associated with VP following sleeve gastrectomy.

Outcome Measures

Primary Outcomes (1)

  • The patient-reported pain scores using an 11-point visual analog scale for pain( 11 being the worse pain).

    An analog pain scale survey was administered by an investigator blinded to the patients' groups at 1 hour postoperatively (in the recovery room), 8 hours postoperatively, and the following morning

    Outcomes were assessed up to 24 hours after surgery during the period of inpatient admission following LSG.

Secondary Outcomes (10)

  • The secondary outcomes were analgesic requirements.

    The recorded administered doses of analgesics were assessed up 24 hours after surgery during the period of inpatient admission following LSG.

  • The secondary outcome was present of nauseas

    Recorded up to 24 hours after surgery

  • The secondary outcome was present of vomiting

    Recorded up to 24 hours after surgery

  • The secondary outcome was present of retching

    Recorded up to 24 hours after surgery

  • The secondary outcome was present of excessive salivation

    Recorded up to 24 hours after surgery

  • +5 more secondary outcomes

Study Arms (2)

PG-ANB Block

EXPERIMENTAL

The paragastric lesser omentum neural block is performed with a 25-gauge needle attached to a venous catheter extension introduced through the left 12-mm port. The needle is capped during its introduction, and the cap is removed inside the abdomen using a grasper and kept under direct vision. Infiltration of 20 mL of non-diluted 0.5% bupivacaine is performed at six levels with careful aspiration preceding fluid infiltration. Four of the areas are next to the vagus nerves and branches, and two are in the vicinity of the common hepatic and left gastric arteries

Procedure: Paragastric autonomic neural blockade

Control

NO INTERVENTION

No paragastric neural block is performed in the control group. The same standard analgesic protocol consisting of acetaminophen (1 g) and morphine (3-5 mg) is used in all patients before extubation and TAP block is performed in both groups (control and experimental)

Interventions

Paragastric autonomic neural blockade with Bupivacaine

Also known as: Laparoscopic transverses abdomens plane (TAP) block (To Both the control and experimental arms), Laparoscopic sleeve gastrectomy(LSG) to all patients
PG-ANB Block

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Adult patients who were scheduled for LSG at each participating institution from 25 August 2021 to 8 February 2022 and consented to study participation.

You may not qualify if:

  • the performance of concomitant procedures in addition to LSG.
  • allergies to medications included in the postoperative management protocol.
  • anesthetic complications related to the LSG that would alter the postoperative management protocol.
  • surgical complications related to the LSG that would alter the postoperative management protocol.
