Left-lateral decubitus jackknife position for laparoscopic resection of right posterior liver tumors: A safe and effective approach

PURPOSE

To compare outcomes of LLR in VI/VII of the liver in Left-lateral Decubitus Jackknife Position (LDJP) and traditional Supine Position (SP). We used propensity score matching (PSM) to analyze clinical outcomes.

PATIENTS & METHODS

This study retrospectively analyzed patients undergoing LLR for liver tumors in segments VI and/or VII at Shandong Provincial Hospital from 2018 to 2023. A total of 218 cases were included (LDJP, n = 94; SP, n = 124). Matched 1:1 PSM groups were created and clinical indicators compared between groups.

RESULTS

218 LLR patients, 94 LDJP and 124 supine. After 1:1 PSM, each group had 62 patients. No significant differences in clinical or laboratory parameters. All surgeries were successful, 1 LDJP conversion to open resection and 4 SP conversions (P = 0.375). LDJP average surgery duration: 220.6 ± 29.9 min, supine position: 262.6 ± 35.6 min (P < 0.001). LDJP perioperative blood loss: 169.0 ± 74.4 mL, supine position: 231.6 ± 84.6 mL (P < 0.001). Four LDJP patients required intraoperative blood transfusion compared to 16 supine position patients (P = 0.012). All cases had negative margins postoperatively. No significant differences in postoperative complications (8 LDJP vs 9 supine, P = 0.675) or length of hospital stay (25 LDJP vs 26 supine, ≥ 7 days) (P = 1.000).

CONCLUSION

Laparoscopic partial hepatectomy in LDJP for hepatic VI/VII tumor safe and feasible. Reduces operative time, blood loss, transfusion requirement, improving outcomes.

Single incision laparoscopic surgery for hepatocellular carcinoma

Single incision laparoscopic liver resection (SILLR) is the most recent development in the laparoscopic approach to the liver. SILLR for hepatocellular carcinoma (HCC) has developed much more slowly than multiport LLR. So far, 195 patients completed SILLR for HCC. In this paper, we reviewed all published papers about SILLR for HCC and discussed the feasibility of the SILLR, peri and postoperative findings, tricks of patient selection and whether SILLR compromise the oncological principles.

Long-term outcomes of single-port laparoscopic hepatectomy for hepatocellular carcinoma: a retrospective comparative analysis

Purpose

Numerous efforts have been made to achieve minimally invasive surgery, such as single-port laparoscopic surgery. However, few studies have provided long-term follow-up information, and the number of patients with hepatocellular carcinoma (HCC) in previous studies has been small. The purpose in this study is to compare the long-term oncological outcomes of HCC patients who underwent single-port laparoscopic hepatectomy (SPLH) with those of patients who underwent multiport laparoscopic hepatectomy (MPLH).

Methods

We retrospectively reviewed the medical records of 135 patients with HCC who underwent laparoscopic liver between January 2008 and December 2018. Of the 135 patients, 53 underwent MPLH, and 82 underwent SPLH.

Results

From January 2008 to December 2018, 135 patients underwent laparoscopic hepatectomy for HCC. Among them, 82 patients underwent SPLH, and 53 patients underwent MPLH. Neither long-term overall survival (P = 0.849) nor recurrence-free survival (P = 0.057) differed significantly between the 2 groups, even though the recurrence rate was higher in the SPLH group. In the univariable analysis of risk factors for recurrence, multiple tumors, SPLH method, and portal vein invasion were statistically significant (P < 0.05). Multivariable analysis showed that the SPLH method and portal vein invasion were independent adverse prognostic factors for recurrence-free survival.

Conclusion

In terms of both short-term and long-term outcomes, the SPLH method seems to be a feasible approach for HCC in select patients. Because the potential risk of margin recurrence might produce poor oncological outcomes, strict patient selection is essential to ensure that an adequate safety margin can be secured.

Trends in Minimally Invasive Approaches for Liver Resections-A Systematic Review

BACKGROUND

SILS (single incision laparoscopic surgery) and NOTES (natural orifice transluminal endoscopic surgery) are considered breakthroughs in minimally invasive surgery, the first consisting in the surgeon working via a single entrance site and the second via a natural orifice (e.g., oral cavity).

METHODS

Since 2000 until 2022, the original articles published in the online databases were analyzed. Eligible studies included information about the current therapy of patients with liver surgical pathology and how the two new techniques improve the surgical approach.

RESULTS

A total of 798 studies were identified. By applying the exclusion criteria, nine studies remained to be included in the review. Two out of nine studies examined the NOTES approach in liver surgery, whereas the other seven focused on the SILS technique. The age of the patients ranged between 24 and 83 years. Liver resections for hepatocellular carcinoma or colorectal metastases were undertaken and biliary or hydatid cysts were removed. The mean procedure time was 95 to 205 min and the average diameter of the lesions was 5 cm.

CONCLUSIONS

When practiced by multidisciplinary teams, transvaginal liver resection is feasible and safe. The goals of SILS and NOTES are to be less intrusive, more easily tolerated and aesthetic.

Single-incision laparoscopic surgery to treat hepatopancreatobiliary cancer: A technical review

Single-incision laparoscopic surgery (SILS), or laparoendoscopic single-site surgery, was launched to minimize incisional traumatic effects in the 1990s. Minor SILS, such as cholecystectomies, have been gaining in popularity over the past few decades. Its application in complicated hepatopancreatobiliary (HPB) surgeries, however, has made slow progress due to instrumental and technical limitations, costs, and safety concerns. While minimally invasive abdominal surgery is pushing the boundaries, advanced laparoscopic HPB surgeries have been shown to be comparable to open operations in terms of patient and oncologic safety, including hepatectomies, distal pancreatectomies (DP), and pancreaticoduodenectomies (PD). In contrast, advanced SILS for HPB malignancy has only been reported in a few small case series. Most of the procedures involved minor liver resections and DP; major hepatectomies were rarely described. Single-incision laparoscopic PD has not yet been reported. We herein review the published SILS for HPB cancer in the literature and our three-year experience focusing on the technical aspects.

Standardized single-incision plus one-port laparoscopic left lateral sectionectomy: a safe alternative to the conventional procedure

Purpose

Laparoscopic left lateral sectionectomy (LLLS) is a feasible and safe procedure with a relatively smooth learning curve. However, single-incision LLLS requires extensive surgical experience and advanced techniques. The aim of this study is to report the standardized single-incision plus one-port LLLS (reduced port LLLS, RPLLLS) technique and evaluate its safety, feasibility, and effectiveness for junior surgeons.

Methods

Between January 2008 and November 2020, the clinical records of 49 patients who underwent LLLS, divided into the conventional LLLS (n = 37) and the RPLLLS group (n = 12), were retrospectively reviewed. The patient characteristics, pathologic results, and operative outcomes were evaluated.

Results

A history of previous abdominal surgery in the RPLLLS group was significantly high (56.8% vs. 91.7%, p = 0.552). Notably, junior surgeons performed 62.2% of the conventional LLLSs and 58.4% of the standardized RPLLLSs. There were no significant differences between the two groups in terms of median operative time (121.0 vs. 113.5, p = 0.387), median blood loss (13.0 vs. 8.5, p = 0.518), median length of hospital stays (7.0 vs. 7.0, p = 0.408), and morbidity rate (2.7% vs. 0%, p = 0.565), respectively.

Conclusion

This standardized RPLLLS is a feasible and safe alternative to conventional LLLS and may become the ideal training procedure for both junior surgeons and surgeons aiming to learn more complex procedures.

Laparoscopic left lateral sectionectomy in pediatric living donor liver transplantation by single-port approach: A case report

BACKGROUND

Single-port laparoscopy has been used in a variety of abdominal operations. We report the first case of single-port laparoscopic left lateral sectionectomy in pediatric laparoscopic living donor liver transplantation.

CASE SUMMARY

A 28-year-old man volunteered for living liver donation to his daughter who was diagnosed with liver cirrhosis and portal hypertension after the Kasai procedure for biliary atresia. His body mass index was 20.5 kg/m². Liver dynamic computed tomography showed: (1) Left lateral graft volume of 232.76 cm³ with a graft-to-recipient weight ratio of 2.59%; and (2) Right hepatic artery derived from the superior mesenteric artery. A single-port access system was placed through a transumbilical incision, including four trocars: two 12-mm ports for a camera and endoscopic stapler and two 5-mm working ports. Liver parenchyma was dissected by a Harmonic and Cavitron Ultrasonic Surgical Aspirator, while bipolar was used for coagulation. The bile duct was transected above the bifurcation by indocyanine green fluorescence cholangiography. The specimen was retrieved from the umbilical incision. The total operation time was 4 h without blood transfusion. The final graft weight was 233.6 g with graft-to-recipient weight ratio of 2.60%. The donor was discharged uneventfully on postoperative day 4.

CONCLUSION

Single-port laparoscopic left lateral sectionectomy is feasible in pediatric laparoscopic living donor liver transplantation in an experienced transplant center.

Single versus multiple port laparoscopic left lateral sectionectomy for hepatocellular carcinoma: A retrospective comparative study

BACKGROUND

Single port laparoscopic hepatectomy has been applied in some surgeries. We aimed to describe our experience with single port laparoscopic left lateral sectionectomy (SPLS) and to compare the safety and feasibility of this technique with those of conventional multi-port laparoscopic left lateral sectionectomy (MPLS) in the treatment of hepatocellular carcinoma (HCC).

METHODS

A total of 72 consecutive patients who underwent SPLS (n = 33) and MPLS (n = 39) for HCC were enrolled. The peri-operative parameters of safety and feasibility, as well as the short-term oncological outcomes were compared.

RESULTS

The length of postoperative hospital stay (LOS) was significantly shorter in the SPLS group than in the MPLS group (4.12 vs. 4.59 days, P = 0.043). No significant difference between the two groups was found in the operation time (104.58 vs. 95.69 min in the SPLS group and MPLS group respectively, P = 0.353) or the amount of blood loss (62.73 vs. 68.46 ml, P = 0.595). The 1-year recurrence-free survival rate was 77.9% in the SPLS group and 70.7% in the MPLS group (P = 0.82). Subgroup analysis showed that for patients without cirrhosis, the LOS was shorter in the SPLS group than in the MPLS group (P = 0.033), while for patients with cirrhosis, the LOS was not significantly different between the two groups (P = 0.201), although it was shorter in the SPLS group.

CONCLUSIONS

SPLS was a feasible and safe surgical approach for the treatment of HCC on left lateral section.
