Results
A total of 74 patients including 16 in Group 1 and 58 in group 2 were included in the study. Amount of wild pear which patients in Group 1 consumed was median 600 grammes (range, 450-800 gr). All patients in Group 1 were admitted to the hospital between the end of August and the end of November and that period was consistent with the harvesting period of wild pears.
The median age in Group 1 and Group 2 was 55 (range, 23-74) and 60.5 (range, 18-93), respectively. Male to female ratio was 7 in Group 1 and it was statistically significantly higher compared to Group 2 (p=0.01). Comorbid diseases were more common in Group 2 and hypertension (n=15) and diabetes mellitus (n=10) were the most seen comorbidities in study group. Age, comorbidities and history of previous operation were comparable between groups. History of previous SBO was significantly higher in Group 2 (p=0.032). Patients in Group 2 had significantly abnormal levels of WBC, CRP and BUN compared to Group 1 (all p<0.05), however, there was no difference in levels of creatinine, potassium and BUN/creatinine ratio between groups (all p>0.05). Group 1 was associated with a shorter duration of complaints and shorter length of hospital stay and also faster clinical recovery (all p<0.05). Surgical intervention was required for six patients (10.3%) in Group 2. Four patients (6.9%) underwent surgery on the fourth day of admission due to the absence of clinical improvement. Other two (3.4%) patients developed an acute abdomen in the second day of admission and taken into exploratory laparotomy. Adhesiolysis in four (6.9%), and segmental intestinal resection and anastomosis were performed in two patients (3.4%). Intestinal resection and anastomosis required only in those who developed an acute abdomen. Postoperative superficial surgical site infection and urinary tract infection were developed in two patients (3.4%) and in one patient (1.7%), respectively. Although the mean follow-up period was significantly longer in Group 1 compared to Group 2, no recurrence occurred. In group 2, SBO was relapsed in none of the patients who underwent laparotomy. However, 11 patients (21.2%) among 52 patients conservatively managed readmitted to the hospital due to recurrence of SBO during a median of 11-month (range, 7-22 months) follow-up. All patients were treated conservatively again. The demographic characteristics and clinicopathologic features of patients are summarized in Table 1 .
