Hartmann's Reversal: Controversies of a Challenging Operation.

PURPOSE: Hartmann's reversal is a complex operation with a high morbidity rate. Minimally invasive surgery has been used to reduce the impact of surgery on fragile patients. The aim of this comparative study is to look at the results of Hartmann's reversal procedures with different approaches.

METHODS: All the patients who underwent Hartmann's reversal were collected retrospectively (124 cases). Sixty-four patients (50.4%) had an open operation, 6 cases (5%) were treated with a conventional laparoscopic approach, 34 patients (28.1%) underwent single incision laparoscopic surgery (SILS), and 20 (16.5%) required other additional trocars.

RESULTS: SILS operations were slightly longer than the open procedures (175 min vs 150 min), with the same rate of postoperative complications and reoperations ( p  = 0.83 and p  = 0.42), but with a shorter hospital stay (5 days p  = 0.007). Age ( p  = 0.03), long operative time ( p  = 0.01), and ASA score ( p  = 0.05) were identified as independent factors affecting postoperative morbidity. The grade of adhesions caused a longer operative time ( p  = 0.001) and a higher risk of conversion ( p < 0.001), and short rectal stump increased the risk of protective loop ileostomy ( p  = 0.008). Patients with grade 2-3 of adhesions had a longer length of stay ( p  = 0.05).

CONCLUSIONS: Minimally invasive procedures had a shorter hospital stay and did not show any increase in morbidity rate when compared with open cases. Age, longer operative time, and ASA score increased the risk of postoperative complications. Furthermore, patients with a short rectal stump had a higher chance of having a defunctioning ileostomy.
