Tourniquet modification of the associating liver partition and portal ligation for staged hepatectomy procedure.

BACKGROUND: In staged liver resections, associating liver partition and portal ligation for staged hepatectomy (ALPPS) achieves sufficient hypertrophy of the future liver remnant (FLR) in 7 days. This is based on portal vein ligation and transection, and on occlusion of intrahepatic collaterals. This article presents a new surgical technique for achieving rapid hypertrophy of the FLR, which also involves adding intrahepatic collateral occlusion to portal vein transection. METHODS: Patients scheduled for two-stage liver resection for primary or secondary liver tumours, in whom the FLR was considered too small, were enrolled prospectively. In the first stage, a tourniquet was placed around the parenchymal transection line, and the right portal vein was ligated and cut (associating liver tourniquet and portal ligation for staged hepatectomy, ALTPS). The tourniquet was placed on the umbilical ligament if a staged right trisectionectomy was planned, and on Cantlie's line for staged right hepatectomy. RESULTS: From September 2011, 22 ALTPS procedures were carried out (right trisectionectomy in 15, right hepatectomy in 7). Median FLR at 7 days increased from 410 to 700 ml (median increase 61 (range 33-189) per cent). The median duration of the first stage was 125 min and no patient received a blood transfusion. The median duration of the second stage was 150 min and five patients required a blood transfusion. Fourteen patients had complications, most frequently infected collections, and five patients developed postoperative liver failure. Two patients died. CONCLUSION: The ALTPS technique achieved adequate hypertrophy of the FLR after 7 days. It may provide a less aggressive modification of the ALPPS procedure.

Comparative study of right portal vein ligation versus embolisation for induction of hypertrophy in two-stage hepatectomy for multiple bilateral colorectal liver metastases.

AIM: In patients with two-stage hepatectomy (TSH) for multiple bilobar liver metastases from colorectal cancer, few clinical series compare functional remnant hypertrophy of the liver volume between right portal vein ligation (PVL) and embolisation (PVE). Our objective is to analyse the effectiveness of portal vein ligation to achieve hypertrophy of the functional remnant volume (FRV) of the liver and to compare the results with portal vein embolisation in a series of patients with multiple bilobar liver metastases from colorectal carcinoma. PATIENTS AND METHODS: Between September 2001 and September 2011 we performed a TSH in 41 patients with multiple bilobar colorectal liver metastases. A right PVL was performed in 23 patients with an insufficient FRV (three patients did not complete the second stage due to tumour progression and were excluded). We prospectively compare these results with the increased remnant volume obtained in 18 patients with right PVE. RESULTS: The median FRV was higher in the patients with PVE, rising from 501 ml (range 309-703) to 636 ml (range 387-649), than those with PVL, rising from 510 ml (range 203-824) to 595 ml (range 313-1213) (p < 0.05). The median %FRVI was higher in the patients with PVE (median 40%; range 21-65%) than those with PVL (median 30%; range 21-60%) (p < 0.05). CONCLUSIONS: PVL and PVE were effective in all cases for obtaining hypertrophy of the FRV before major liver resection. Right PVE obtains better results and should be used where necessary to achieve a further increase in volume.

[Rupture of the thoracic esophagus by compressed air]. / Estallido del esófago torácico por aire comprimido.

A case of rupture of the oesophagus due to the accidental passage of compressed air through the mouth is reported. Two longitudinal lacerations were present in the thoracic oesophagus; they were treated by radical oesophagectomy cervical oesophagostomy and gastrostomy for feeding. Reconstruction was made by retrosternal coloplasty. The course of the patient was uneventful.

[Rupture of an aneurysm of the hepatic artery proper and acute cholecystitis]. / Rotura de aneurisma de arteria hepática propia y colecistitis aguda.

The authors report the case of a hepatic artery aneurysm which ruptured into the peritoneal cavity in the course of acute, gangrenous cholecystitis, which was treated successfully. The clinical aspects of the case, its evolution and the histological study, which appeared to indicate that adjacent inflammation was the cause of the rupture, are discussed. Treatment of hepatic artery aneurysms is conditioned to a great degree by the gravity of the onset, and in most cases ligature is the only feasible procedure. Other forms of treatment may be possible when the aneurysm is intrahepatically located or it is diagnosed before rupture.
