  • Title: Laparoscopy as a Diagnostic and Therapeutic Modality for Chronic Abdominal Pain of Unknown Etiology: A Literature Review.
    Author: Zhao J, Samaan JS, Toubat O, Samakar K.
    Journal: J Surg Res; 2020 Aug; 252():222-230. PubMed ID: 32289579.
    Abstract:
    BACKGROUND: Investigate the diagnostic and therapeutic utility of laparoscopy in the management of patients with chronic abdominal pain of unknown origin. METHODS: Ovid MEDLINE, PubMed, and SCOPUS databases were queried to identify relevant published studies. Data on the diagnostic and therapeutic utility of laparoscopy were abstracted and summarized. RESULTS: Laparoscopy achieved a diagnosis in 65% to 94% of patients with chronic abdominal pain of unknown origin. Common intraoperative findings included adhesions, chronic appendicitis, hernias, and enlarged mesenteric lymph nodes. These findings corresponded with the therapeutic procedures that were performed, including laparoscopic adhesiolysis, appendectomy, and hernia repair. Therapeutic utility of laparoscopy based on pain relief, patient satisfaction, and quality of life ranged from 63% to 94%. CONCLUSIONS: Based on current available evidence, diagnostic laparoscopy (DL) is a safe and effective method for identifying organic causes of chronic abdominal pain. Laparoscopic treatment also resulted in substantial pain relief for a majority of patients. However, the efficacy of laparoscopic adhesiolysis remains controversial. We would recommend the use of DL as an early diagnostic tool, but more robust studies are needed to establish the breadth of its therapeutic utility in clinical practice.
