Laparoscopic total colectomy for ulcerative colitis after liver transplantation is feasible

Surgical management of colon cancer in ulcerative colitis patients with orthotopic liver transplant for primary sclerosing cholangitis. A systematic review

INTRODUCTION

Colon cancer in ulcerative colitis patients with liver transplant (UCCOLT) due to primary sclerosing cholangitis carries significant treatment challenges. Aim of this literature search is to review management strategies and provide a framework to facilitate the decisional process in this clinical setting.

METHODS

PRISMA-compliant systematic search was followed by critical expert commentary of the results and development of a surgical management algorithm. Endpoints included surgical management, operative strategies, functional and survival outcomes. Technical and strategics aspects with particular regard to the choice of reconstruction were evaluated to tentatively develop an integrated algorithm.

RESULTS

Ten studies reporting treatment of 20 UCCOLT patients were identified after screening. Nine patients underwent proctocolectomy and end-ileostomy (PC) and eleven had restorative ileal pouch-anal anastomosis (IPAA). Reported results for perioperative outcomes, oncological outcomes, and graft loss were comparable for both procedures. There were no reports of subtotal colectomies and ileo-rectal anastomosis (IRA).

CONCLUSIONS

Literature in the field is scarce and decision-making is particularly complex. PC and IPAA have been reported with good results. Nevertheless, IRA may also be considered in UCCOLT patients in selected cases, reducing the risks of sepsis, OLT and pouch failure; furthermore, in young patients, it has the advantage of preserving fertility or sexual function. The proposed treatment algorithm may represent a valuable support in guiding surgical strategy.

Minimally invasive surgery and liver transplantation: is it a safe, feasible, and effective approach?

The minimally invasive approach (MIS) is undoubtedly one of the most important breakthroughs in surgery in recent decades. Consequently, MIS has been increasingly in the field of liver transplantation (LT). The objective of the present review was to determine the current status of MIS with respect to liver transplantation (LT) and what would be the indications for an MIS in this context today. The literature was searched for publications reporting the MIS in LT. Only those articles that described the results according to whether the MIS had been performed to treat transplant complications (urgent or late), another pathology not related to the LT, or to perform the liver explantation and graft implantation were included. From 2000 to 2022, 33 studies and 261 patients were included. Most frequent indications were incisional hernias secondary to LT followed by the treatment of other pathologies not related with the LT and treatment of LT complications. Only a 12% were urgent interventions. Few studies describe conversions with an average rate of 2.5%. Morbidity do not differ significantly from open surgery. No case of mortality or graft loss was described. Purely laparoscopic liver explants in 9 patients with 2 conversions and 3 cases of graft implantation with a higher warm ischemia in the MIS implants grafts were described. The limitations of MIS in LT are relative and probably depend more on training, experience, and skills of the surgeons. This approach could be safety and feasibility to solved complications or in other individualized indications in LT patients. The initial experiences in liver explant and graft implantation need further investigations.

Laparoscopic right colectomy for colon cancer after liver transplantation

The incidence of colorectal cancer (CRC) after liver transplantation is 0.5%–4%. Laparoscopic surgery is the standard-of-care treatment, however it is rarely performed in patients who had previously undergone liver transplantation. Few reports exist regarding minimally invasive surgery in such context and none about laparoscopic right colectomy. We present the case of a 64-year-old female with a history of liver transplantation in 2001 and who developed a right-sided CRC. A laparoscopic right colectomy was successfully performed, and the post-operative course was uneventful. Given the known benefits, we believe that laparoscopic approach should be considered in such patients.
