Intraperitoneal rupture of the hydatid cyst disease: Single-center experience and literature review.

BACKGROUND

The primary aim of this study was to present our experience on intraperitoneal rupture of the hydatid cyst in guidance of literature data.

METHODS

Demographical, clinical, radiological and postoperative follow-up data of 29 patients who underwent surgical treatment in our institution with an indication of intraperitoneal rupture of the hydatid cyst from January 2003 to July 2020 were analysed retropectively.

RESULTS

Among the 29 patients with an age range of from 16 to 79 years ( median= 39, IQR=25.5), 16 were male (55.2%) and 13 were female (44.8%). Intraperitoneal rupture of the hydatid cyst was spontaneous in 21 (72.4%), traumatic in 7 (24.13%) (2 of them were iatrogenic) and was due to shotgun in one patient. Vast majority of the patients were admitted to the emergency department in the first 24 hours after the onset of sign and symptoms. WBC varied from 8.600 to 30.900/mm3 (median=12.100, IQR=5.7). Ruptured cysts were localised in liver (n=25, 86.2%), in spleen (n=2, 6.89%) or in pelvis (n=2, 6.89%) and diameter varied from 40 to 200 mm (median= 90, IQR=50). Among the cysts ruptured in liver, 19 (76%) of them were localised in right lobe. Among the ruptured cysts of liver, 20 (80%) of them underwent conservative surgery (partial pericystectomy etc), remaining 5 patients (20%) underwent a radical surgical treatment (pericystectomy etc). A biliary orifice was diagnosed during surgical exploration in either cyst cavity or cut surface of liver in 12 (48%) of the patients. Patients with a dilated common bile duct or a visible biliary duct orifice in cystic cavity underwent common bile duct exploration and T-tube drainage procedure (n=6, 24%). One patient died on postoperative day one, due to cardiopulmonary complications secondary to cyst rupture. All along the postopeartive follow-up of median 1416 days, seven (24.1%) patients were diagnosed for diseased recurrence.

CONCLUSION

Intraperitoneal rupture of the hydatid cyst is a life-threatening complication of hydatid cyst disease, for which diagnosis without delay and timing of surgical treatment is essential. Anaphylactic shock cases require rapidly initiation of medical treatment against allergic reactions. Despite scolocidal agents, vesicular spread into peritoneal cavity account for the major risk factor for disease recurrence. Hence, abdominal cavity should be explored cautiously.
