Laparoscopic Approach Compared With Conventional Open Approach for Bezoar-Induced Small-Bowel Obstruction

Abstract

Background: Bezoar-induced small-bowel obstruction (SBO) is an uncommon surgical emergency. Accurate preoperative diagnosis is notoriously difficult, and conventional management often necessitates laparotomy. Recent articles demonstrate the feasibility of laparoscopy in the management of SBO. This study compares the outcomes of a series of cases managed laparoscopically with the outcomes of matched open cases. Hypothesis: Laparoscopic management of bezoarinduced SBO is safe and effective when compared with traditional laparotomy treatment. Patients and Methods: A retrospective study was conducted from November 1, 1998, to November 30, 2003, to compare laparoscopic vs open treatment for bezoarinduced SBO. Patients' demographics, operative details, and surgical outcomes were evaluated. Results: During the study period, 24 patients (16 men and 8 women) with a mean age of 68.2 years underwent operative treatments for bezoar-induced SBO. Ten patients received laparoscopic treatments and the other 14 received laparotomy treatments. The patients were comparable in age, sex, and physiological status. There were 3 conversions in the laparoscopy group owing to technical difficulties. The laparoscopic approach was associated with statistically significant shorter operative time (P=.048), fewer postoperative complications (P=.04), and reduced hospital stay (P=.009). Conclusions: When expertise is available, laparoscopy is safe and effective in the management of bezoar-induced SBO and is associated with superior postoperative outcomes when compared with the conventional open approach.

An uncommon case of small bowel obstruction due to phytobezoar in a known case of tubercular abdomen: a decisional dilemma

“…The major difficulty for laparoscopic management are the size of bezoar and the presence of distended and fragile bowel loops. 13 …”

An Interesting Case of Trichobezoar

“…In addition, due to the rarity of trichobezoars, the technique of laparoscopic removal and inspection of the entire intestine may be hard to acquire. The benefits of laparoscopic removal of trichobezoars with intestinal obstruction have been reported to have better cosmetic result, less postoperative complications and reduced admittance time 31 .…”

“…Laparoskopik ya da açık cerrahi yapılabileceği gibi kombine "el yardımlı laparoskopik cerrahi" de planlanabilir. Genel avantajları göz önüne alındığında deneyimli merkezlerde laparoskopik cerrahinin tercih edilmesi önerilmektedir 33 . Ancak halen açık cerrahi en sık uygulanan yöntem-dir 2,12,15 .…”
