Sigmoid resection can be performed using conventional and laparoscopic methods. There are few publications in the literature reporting specimen removal from the natural hole in patients with a diagnosis of sigmoid volvulus. Here, the investigators aimed to present the literature that transanal specimen removal is a technically feasible method after laparoscopic surgery in patients with sigmoid volvulus.

Sigmoid resection can be performed using conventional and laparoscopic methods. There are few publications in the literature reporting specimen removal from the natural hole in patients with a diagnosis of sigmoid volvulus. Here, the investigators aimed to present the literature that transanal specimen removal is a technically feasible method after laparoscopic surgery in patients with sigmoid volvulus. The documents of patients who were operated on for sigmoid volvulus between 2018 and 2019 were retrospectively reviewed. Patients who had been used transanal for specimen extraction by elective laparoscopic sigmoid colon resection were included in the study. Patients' gender, age, comorbidity, operation time, operative difficulties, complications, length of stay, and mortality findings were analyzed. Laparoscopic sigmoid resection and transanal specimen removal were performed in eight patients. Specimen extraction surgery from the natural hole is increasingly preferred. the investigators think that natural hole surgery can be performed more easily and reliably in sigmoid volvulus due to the large diameter of the colon.

Inclusion Criteria:

• transanal for specimen extraction by elective laparoscopic sigmoid colon resection

Exclusion Criteria:

• emergency surgery
• conventional open sigmoid resection
• conventional laparoscopic sigmoid resection
