Results

Laparoscopic distal pancreatectomy was associated with lower inhospital mortality during the period of admission (0.0% vs 0.7%, P<0.001) and within 30 days (0.0% vs 0.2%, P=0.001), incidence of reoperation during the period of admission (0.7% vs 1.7%, P=0.018), postpancreatectomy hemorrhage (0.4% vs 2.0%, P<0.001), ileus (1.1% vs 2.8%, P=0.007), and shorter postoperative length of stay (17 vs 20 d, P<0.001).

Baseline Characteristics

We conducted the study using Japanese healthcare databases of Diagnostic Procedure Combination (DPC) data provided by Medical Data Vision Co. Ltd. (MDV, Tokyo, Japan). DPC is a classification that combines diagnostic and medical procedures with a per diem payment system in the national Japanese health insurance system, and approximately 1,700 hospitals (20% of all hospitals in Japan) are included under the DPC system. Of these hospitals, MDV collected data from approximately 400 facilities representing about 25% of the acute care hospitals in Japan. From the database, we identified patients who underwent distal pancreatectomy between April 2008 and May 2020. We defined the primary underlying disease for which the surgery was performed, using the ICD-10 codes (C250-259, D136, D137, D377, K86) from the database of the primary diseases, underlying disease that triggered hospitalization, and the disease that required the most medical resources. We excluded patients whose information was incomplete (e.g., missing information about clinical cancer stage, body mass index, and smoking index).

Adverse events

None in particular.

Outcome measures

Patient outcomes included in-hospital mortality, morbidity, postoperative length of stay, reoperation during the period of admission, 30-day readmission after discharge, and medical cost. Morbidities included postoperative pancreatic fistula (POPF) (K868), post-pancreatectomy hemorrhage (PPH) (K661, R58, T810, T811), surgical-site infection (SSI) (T793, T814, T813, T941), peritoneal abscess (K65), ileus and bowel obstruction (K560, K562, K565-567, K913), respiratory failure (J12-18, J690, J691, J958, J959, J96), pulmonary embolism (I26), acute coronary syndrome (I21-25), stroke (I60-66), acute renal failure (N17), urinary tract infection (N10, N30, N390), and sepsis (A021, A227, A241, A267, A282, A327, A394, A40, A41, A548, B007, B349, B377).
