| Summary: | Abstract Background Repeat laparoscopic surgery has become increasingly common. However, reports of liver resection after pancreatoduodenectomy are scarce, and we report the first successful case of a patient who underwent laparoscopic liver resection after laparoscopic pancreatoduodenectomy. Case presentation A 65-year-old man underwent laparoscopic pancreatoduodenectomy for ampulla of Vater adenocarcinoma. According to the American Joint Committee on Cancer (8th edition) staging guidelines, the tumour was labelled as stage IIIB (fT2N2M0). Twelve months later, a computed tomography (CT) scan revealed liver masses (in segments 3 and 5) and swollen para-aortic lymph nodes. After six chemotherapy courses of gemcitabine with cisplatin, the CT scan showed the disappearance of the para-aortic lymph nodes and progression of liver metastases. Nineteen months after the initial surgery, the patient underwent laparoscopic partial liver resection of segment 5 and left lateral sectionectomy. First, we performed the operation in the left half lateral decubitus position. In this position, the portal vein was isolated safely without hindering the hepato-jejunal anastomosis, although the adhesions around the hepato-jejunal anastomosis were dense. Therefore, we were able to perform liver transection safely with vascular inflow control. The operation duration was 235 min, and the volume of blood loss was 100 g. Macroscopically, the resected margins were negative. The patient was uneventfully discharged 12 days after the second operation. Afterwards, drainage was needed because of an intra-abdominal abscess. Currently, he has been alive for 8 months postoperatively, receives chemotherapy to suppress para-aortic lymph node metastases, and has not had another recurrence. Conclusions Liver resection after pancreatoduodenectomy can be performed safely with an innovative body position to isolate the portal vein, which is a key point of the surgery. A laparoscopic approach for liver resection after pancreatoduodenectomy is a feasible option.
