Wrapping pancreaticojejunostomy using the ligamentum teres hepatis during laparoscopic pancreaticoduodenectomy: a propensity score matching analysis.

BACKGROUND AND OBJECTIVE: It is controversial whether wrapping around the pancreaticojejunostomy (PJ) could reduce the rate of postoperative pancreatic fistula (POPF), especially in laparoscopic pancreaticoduodenectomy (LPD). This study aims to summarize our single-center initial experience in wrapping around PJ using the ligamentum teres hepatis (LTH) and demonstrate the feasibility and safety of this method. METHODS: Patients who underwent LPD applying the procedure of wrapping around the PJ were identified. The cohort was compared to the cohort with standard non-wrapping PJ. A 1:1 propensity score matching (PSM) was performed to compare the early postoperative outcomes of the two cohorts. Risk factors for POPF were determined by using univariate and multivariate logistic regression analysis. RESULTS: Overall, 143 patients were analyzed (LPD without wrapping (n = 91) and LPD with wrapping (n = 52)). After 1:1 PSM, 48 patients in each cohort were selected for further analysis. Bile leakage, DGE, intra-abdominal infection, postoperative hospital stays, harvested lymph nodes, and R0 resection were comparable between the two cohorts. However, the wrapping cohort was associated with significantly less POPF B (1 vs 18, P = 0.003), POPF C (0 vs 8, P = 0.043), and Clavien-Dindo classification level III-V (5 vs 26, P = 0.010). No patients died due to the clinically relevant POPF in the two cohorts. No patients who underwent the LTH wrapping procedure developed complications directly related to the wrapping procedure. After PSM, whether wrapping was an independent risk factor for POPF (OR = 0.202; 95%CI:0.080-0.513; P = 0.001). CONCLUSIONS: Wrapping the LTH around the PJ technique for LPD was safe, efficient, and reproducible with favorable perioperative outcomes in selected patients. However, further validations using high-quality RCTs are still required to confirm the findings of this study.

Favorable Outcome of Repeated Salvage Surgeries for Rare Metastasis to the Ligamentum Teres Hepatis and the Upper Abdominal Wall in a Stage IV Gastric Cancer Patient.

Gastric cancer with peritoneal metastases is typically a devastating diagnosis. Ligamentum teres hepatis (LTH) metastasis is an extremely rare presentation with only four known cases. Herein, we report salvage surgery of successive metastases to the abdominal wall and LTH in a patient originally presenting with advanced gastric cancer with peritoneal metastasis, leading to long-term survival. A 72-year-old man with advanced gastric cancer underwent curative-intent distal gastrectomy with D2 lymph node dissection for gastric outlet obstruction. During this procedure, three small peritoneal metastases were detected in the lesser omentum, the small mesentery, and the mesocolon; however, intraoperative abdominal lavage cytology was negative. We added cytoreductive surgery for peritoneal metastasis. The pathological diagnosis of the gastric cancer was tubular adenocarcinoma with pT4aN1pM1(PER/P1b)CY0 stage IV (Japanese classification of gastric carcinoma/JCGC 15th), or T4N1M1b stage IV (UICC 7th). Post-operative adjuvant chemotherapy with S-1 (TS-1)+cisplatin (CDDP) was administered for 8 months followed by S-1 monotherapy for 4 months. At 28 months after the initial surgery, a follow-up computed tomography (CT) detected a small mass beneath the upper abdominal wall. The ass showed mild avidity on 18F-fluorodeoxyglucose positron-emission (FDG-PET) CT. Salvage resection was performed for diagnosis and treatment, and pathological findings were consistent with primary gastric cancer metastasis. At 49 months after the initial gastrectomy, a new lesion was detected in the LTH with a similar level of avidity on FDG-PET CT as the abdominal wall metastatic lesion. We performed a second salvage surgery for the LTH tumor, which also showed pathology of gastric cancer metastasis. There has been no recurrence up to 1 year after the LTH surgery. With multidisciplinary treatment the patient has survived almost 5 years after the initial gastrectomy. Curative-intent gastrectomy with cytoreductive surgery followed by adjuvant chemotherapy for advanced gastric cancer with localized peritoneal metastasis might have had a survival benefit in our patient. Successive salvage surgeries for oligometastatic lesions in the abdominal wall and the LTH also yielded favorable outcomes.

Applications of hepatic round ligament/falciform ligament flap and graft in abdominal surgery-a review of their utility and efficacy.

BACKGROUND AND PURPOSE: Despite their ubiquitous presence, easy availability and diverse possibilities, falciform ligament and hepatic round ligament have been used less frequently than their potential dictates. This article aims to comprehensively review the applications of hepatic round ligament/falciform ligament flap and graft in abdominal surgery and assess their utility and efficacy. METHODS: Medical literature/indexing databases were searched, using internet search engines, for pertinent articles and analysed. RESULTS: The studied flap and graft have found utility predominantly in the management of diaphragmatic hernias, gastro-oesophageal reflux disease, peptic perforations, biliary reconstruction, venous reconstruction, post-operative pancreatic fistula, post-pancreatectomy haemorrhage, hepatic cyst cavity obliteration, liver bleed, sternal dehiscence, splenectomy, reinforcement of aortic stump, feeding access, diagnostic/therapeutic access into portal system, composite tissue allo-transplant and ventriculo-peritoneal shunting where they have exhibited the desired efficacy. CONCLUSIONS: Hepatic round ligament/falciform ligament flap and graft are versatile and have multifarious applications in abdominal surgery with some novel and unique uses in hepatopancreaticobiliary surgery including liver transplantation. Their evident efficacy needs wider adoption to realise their true potential.

Wrapping the stump of the gastroduodenal artery using the ligamentum teres hepatis during laparoscopic pancreaticoduodenectomy: a center's preliminary experience.

BACKGROUND: The present study aims to assess the preliminary outcomes of the effectiveness of wrapping the ligamentum teres hepatis (LTH) around the gastroduodenal artery stump for the prevention of erosion hemorrhage after laparoscopic pancreaticoduodenectomy (LPD). METHODS: We reviewed 247 patients who had undergone LPD between January 2016 and April 2019. The patients were divided into two groups according to whether LTH wrapped the stump of the gastroduodenal artery: group A (119 patients) who underwent the LTH wrapping procedure, and group B (128 patients) who did not undergo the procedure. The perioperative data from the two groups were reviewed to assess the effectiveness of the LTH procedure for the prevention of postpancreatectomy hemorrhage (PPH) and other complications. RESULTS: No differences were observed in the clinical characteristics between the two groups. The data from 247 patients were acceptable for analysis: 119 patients underwent wrapping, and 128 patients did not. The incidence of clinically relevant pancreatic fistula (8.4% vs 3.9%), biliary fistula (2.5% vs 1.6%), intra-abdominal infection (10.1% vs 3.9%) and delayed gastric emptying (13.4% vs 16.4%) showed no significant difference between group A and group B. The 90-day mortality and 90-day reoperation rates (0.8% vs 0.8% and 5.0% vs 3.1%) were also similar between group A and group B. Furthermore, postpancreatectomy hemorrhage of Grade B and C occurred in 0 patients (0.0%) in the wrapping group, which was significantly less frequent than the occurrence in the nonwrapping group (7 patients; 5.5%, P = 0.02). CONCLUSIONS: Wrapping the LTH around the gastroduodenal artery stump after LPD does not reduce the incidence of clinically relevant pancreatic fistula, biliary fistula or delayed gastric emptying. However, this procedure has a trend of reducing the rate of PPH of Grade B and C after LPD and is simple to perform.

Pancreaticojejunostomy with or without reinforcement after pancreaticoduodenectomy: surgical technique of ligamentum teres hepatis wrap around pancreaticojejunostomy.

In a previous issue of the Journal, Zhong et al. reported a retrospective study that compared the perioperative outcomes of the mesh-reinforced pancreaticojejunostomy with conventional pancreaticojejunostomy. They concluded that mesh-reinforced pancreaticojejunostomy was a safe and effective technique, as it provided a safe anchor site for suture, thus reducing the risk of pancreatic leakage. Considering these encouraging results, we present a further simple technique using ligamentum teres hepatis wrap around pancreatojejunostomy for prevention of postoperative pancreatic fistula after pancreaticoduodenectomy.

An Analysis of the Anomalous Fissure of the Ligamentum Teres Hepatis: A Morphological Perspective in the North Indian Population.

Background The liver, being the largest internal organ of the body shows a variety of gross morphological variations about lobes, fissures and processes which may be clinically significant. Among various anatomical variations, the most found is the variant fissure for ligamentum teres hepatis. The present study was done to classify, review, compare and discuss the literature for anomalies in fissures for ligamentum teres hepatis. Methods A total of 100 formalin-preserved human livers were obtained from the Department of Anatomy of King George's Medical University, Lucknow, and studied for one year. Result In our study, 15% of the liver showed morphological variations in fissures for ligamentum teres hepatis. These were classified into four types. In type I (2%), the fissure was converted into a tunnel by pons hepatis. In type II (3%), there was an incomplete fissure for ligamentum teres hepatis extending into the diaphragmatic surface. In type III (4%), there was an incomplete fissure for ligamentum teres hepatis present only on the visceral surface. In type IV (6%), the fissure was covered by a thin membrane. Conclusion In this study of the North Indian population, 15% of liver have gross morphological variations. So thorough anatomical knowledge of the existence of variant or abnormal surface features on the liver is imperative to understanding the underlying pathology for radiologists and surgeons so that a favorable outcome can be achieved.

Utility of ligamentum teres hepatis flap reinforcement to prevent postoperative pancreatic fistulas in robotic distal pancreatectomy.

BACKGROUND: Postoperative pancreatic fistula (POPF) is a significant contributor to morbidity and mortality after robotic distal pancreatectomy (RDP). Ligamentum teres hepatis (LTH) reinforcement of the pancreatic remnant may reduce the incidence of POPF. METHODS: Patients ≥18 years old, who underwent RDP at the University of Massachusetts Memorial Medical Center from 01/01/2018-08/31/2022. Primary endpoint was POPF incidence. Secondary outcomes included peri- and postoperative variables. RESULTS: Thirty-three patients underwent RDP, of which LTH reinforcement was used in 21 (64 â€‹%) cases. Six (18 â€‹%) patients developed a POPF. No association was identified between LTH flap reinforcement and POPF (OR 1.18, 95 â€‹% CI 0.18 to 7.85, p â€‹= â€‹0.87). There were no peri- or postoperative complications related to ligamentum teres flap creation. CONCLUSIONS: LTH reinforcement of the pancreatic remnant can be safely performed during RDP. Further studies are needed to assess the utility of this intervention to mitigate the risk of pancreatic fistula formation following RDP.

Safety and Feasibility of Electro-Vaporization of Ligamentum Teres Hepatis in Totally Laparoscopic Gastrectomy.

Introduction: The ligamentum teres hepatis may block the field of vision during totally laparoscopic gastrectomy (TLG), especially in patients with obesity. Aim: We used electrocautery to increase the visual field of TLG by shrinking the ligamentum teres hepatis. This procedure is termed electro-vaporization of the ligamentum teres hepatis (EVLTH). Methods: Patients with body mass index (BMI) ≥24 who underwent total laparoscopic distal gastrectomy (TLDG) or total laparoscopic total gastrectomy (TLTG) between January 2020 and December 2023 were retrospectively enrolled. According to the scope of gastrectomy and whether the patients underwent EVLTH, the patients were divided into the TLDG-EVLTH, TLDG-NEVLTH, TLTG-EVLTH, and TLTG-NEVLTH groups. The clinical characteristics, surgical outcomes, and pathological features were compared between the TLDG-EVLTH and TLDG-NEVLTH groups and the TLTG-EVLTH and TLTG-NEVLTH groups. Results: This study included 65 patients who underwent TLDG (EVLTH: NEVLTH = 29:36) and 32 patients who underwent TLTG (EVLTH:NEVLTH = 15:17). There were no significant differences in clinical characteristics, surgical outcomes, and pathological features between the TLDG-EVLTH and TLDG-NEVLTH groups. However, the operation time in the TLTG-EVLTH group was significantly shorter than that in the TLTG-NEVLTH group, and the difference was statistically significant, although differences in other data were not statistically significant. Conclusions: EVLTH is a simple and safe procedure that reduces the operation time of TLTG in patients who are overweight and enhances the field of vision of TLG.

Primary Necrosis of the Ligamentum Teres Hepatis: A Rare Cause of Acute Abdominal Pain.

Primary necrosis of the ligamentum teres hepatis (PNLTH) is an extremely rare disease which presents with acute abdominal pain. It has easily been misdiagnosed due to lack of clinical manifestations. Early recognition of PNLTH is crucial for treatment while CT is a good methed to diagnose and differential diagnose PNLTH. Teaching Point: Primary necrosis of the ligamentum teres hepatis (PNLTH) is an extremely rare disease characterized with acute abdominal pain, while computed tomography is the recommended technique to diagnose and differential diagnose this disease.

Ligamentum teres hepatis wrapping of the gastroduodenal artery stump for protection in total laparoscopic pancreaticoduodenectomy: a single-center experience.

OBJECTIVE: Hemorrhage from the stump of the gastroduodenal artery (GDA) is a significant postoperative risk with pancreaticoduodenectomy (PD). Studies have shown that wrapping the GDA stump using the omentum or the falciform ligament can help prevent bleeding. We aimed to determine whether wrapping the GDA stump with the ligamentum teres hepatis (LTH) would reduce postoperative PD hemorrhage. METHODS: We retrospectively reviewed data for 148 patients who underwent laparoscopic pancreatoduodenectomy (LPD) at our hospital from November 2015 to September 2021. We compared perioperative data from 63 LPD patients without wrapping of the GDA (unwrapped group) and 85 whose GDA stumps were wrapped (wrapped group). RESULTS: There were no significant differences in the groups' baseline characteristics. The postoperative GDA stump bleeding incidence was significantly lower in the wrapped group than that in the unwrapped group (7.9% vs. 0, respectively). There was also no significant difference in the incidence of other complications (intra-abdominal infection, postoperative pancreatic fistula (POPF), biliary fistula, and gastrointestinal bleeding). CONCLUSION: Using the LTH to wrap the GDA stump during LPD can reduce bleeding from the GDA stump but not the incidence of other complications.

Ligamentum teres hepatis as a graft for portal and/or superior mesenteric vein reconstruction: From bench to bedside.

BACKGROUND: Pancreaticoduodenectomy combined with portal vein (PV) and/or superior mesenteric vein (SMV) resection in patients with pancreaticobiliary malignancy has become a common surgical procedure. There are various grafts currently used for PV and/or SMV reconstruction, but each of these grafts have certain limitations. Therefore, it is necessary to explore novel grafts that have an extensive resource pool, are low cost with good clinical application, and are without immune response rejection or additional damage to patients. AIM: To observe the anatomical and histological characteristics of the ligamentum teres hepatis (LTH) and evaluate PV/SMV reconstruction using an autologous LTH graft in pancreaticobiliary malignancy patients. METHODS: In 107 patients, the post-dilated length and diameter in resected LTH specimens were measured. The general structure of the LTH specimens was observed by hematoxylin and eosin (HE) staining. Collagen fibers (CFs), elastic fibers (EFs), and smooth muscle (SM) were visualized by Verhoeff-Van Gieson staining, and the expression of CD34, factor VIII-related antigen (FVIIIAg), endothelial nitric oxide synthase (eNOS), and tissue type plasminogen activator (t-PA) were detected using immunohistochemistry in LTH and PV (control) endothelial cells. PV and/or SMV reconstruction using the autologous LTH was conducted in 26 patients with pancreaticobiliary malignancies, and the outcomes were retrospectively analyzed. RESULTS: The post-dilated length of LTH was 9.67 ± 1.43 cm, and the diameter at a pressure of 30 cm H2O was 12.82 ± 1.32 mm at the cranial end and 7.06 ± 1.88 mm at the caudal end. Residual cavities with smooth tunica intima covered by endothelial cells were found in HE-stained LTH specimens. The relative amounts of EFs, CFs and SM in the LTH were similar to those in the PV [EF (%): 11.23 ± 3.40 vs 11.57 ± 2.80, P = 0.62; CF (%): 33.51 ± 7.71 vs 32.11 ± 4.82, P = 0.33; SM (%): 15.61 ± 5.26 vs 16.74 ± 4.83, P = 0.32]. CD34, FVIIIAg, eNOS, and t-PA were expressed in both LTH and PV endothelial cells. The PV and/or SMV reconstructions were successfully completed in all patients. The overall morbidity and mortality rates were 38.46% and 7.69%, respectively. There were no graft-related complications. The postoperative vein stenosis rates at 2 wk, 1 mo, 3 mo and 1 year were 7.69%, 11.54%, 15.38% and 19.23%, respectively. In all 5 patients affected, the degree of vascular stenosis was less than half of the reconstructed vein lumen diameter (mild stenosis), and the vessels remained patent. CONCLUSION: The anatomical and histological characteristics of LTH were similar to the PV and SMV. As such, the LTH can be used as an autologous graft for PV and/or SMV reconstruction in pancreaticobiliary malignancy patients who require PV and/or SMV resection.

Abscess of ligamentum teres hepatis post-endoscopic retrograde cholangiopancreatography: A case report and a literature review.

Abscess of the ligamentum teres hepatis has been described in the medical literature as an extremely rare clinical entity, which often presents a diagnostic dilemma. A 68-year-old man was hospitalized for upper abdominal pain and obstructive jaundice. The patient presented with low-grade intermittent fever. Laboratory investigations showed a white blood cell count of 32.38 × 109/L, a C-reactive protein level of 247.86 mg/L, abnormal liver enzyme and bilirubin levels, and elevated serum levels of amylase and lipase. He was first diagnosed with acute biliary pancreatitis. A computational tomography scan and magnetic resonance cholangiopancreatography revealed obstructive choledocholithiasis and cholecystolithiasis. The patient received preoperative antibiotics and symptomatic treatments for 5 days, followed by endoscopic retrograde cholangiopancreatography and a subsequent duodenal papilla incision to extract pigment and cholesterol gallstones. The patient recovered and was discharged on the fifth day after surgery. However, 10 days later, the patient was readmitted for the recurrence of acute calculous cholecystitis. Laboratory tests showed increases in total and direct bilirubin, γ-glutamyltransferase, and alkaline phosphatase, but not inflammatory parameters. After the patient's nutritional status improved on the 11th day after admission, a laparoscopic cholecystectomy was performed. Intraoperative exploration revealed extensive abdominal adhesions; a thickened edematous gallbladder wall; and an unexpected abscess of the ligamentum teres hepatis. Pus aspiration was performed laparoscopically after laparoscopic cholecystectomy, and to ensure elimination of the abscess, ultrasound-guided pus aspiration was also performed 1 week later. Fortunately, the patient made an uneventful recovery and was discharged with a drain tube on the 16th day after surgery. Doppler ultrasound indicated that the abscess had completely disappeared 2 weeks after discharge. This case highlights an unusual presentation of a ligamentum teres hepatis abscess caused by obstructive cholangitis but that appeared after the choledocholithiasis was resolved. However, the mechanism of abscess formation remained uncertain.

Augmentation of Hiatal Repair with the Ligamentum Teres Hepatis for Intrathoracic Gastric Migration After Bariatric Surgery.

PURPOSE: The augmentation of hiatoplasty (HP) with the ligamentum teres hepatis (LTA) is a new concept for intrathoracic migration of a gastric sleeve or pouch (ITGM). We retrospectively analyzed all cases of hiatal hernia repair in a single center between 2015 and 2019. METHODS: A total of 171 patients underwent 307 hiatal hernia repairs after sleeve gastrectomy (SG) (n = 79), Roux-en-Y gastric bypass (RYGB) (n = 129), and one anastomosis gastric bypass (OAGB) (n = 99). Each hiatal hernia repair was defined as a "case" and assigned to the LTA group or the non-LTA group. The primary outcome was the recurrence of ITGM as detected by endoscopy or CT. RESULTS: The basic characteristics in the LTA group (78 cases) and the non-LTA group (229 cases) were comparable with the exception of the rate of revisional HP (72% vs. 21%), the rate of prior conversion to RYGB (33% vs. 17%), the initial BMI (45.9 ± 8.2 kg/m2 vs. 49.0 ± 8.8 kg/m2), and the follow-up (7 months (1-16) vs. 8 months (1-54)). The ITGM recurrence rate was 15% in the LTA group and 72% in non-LTA group (p < 0.001). Multivariate analysis showed that the length of ITGM and the type of surgical repair were independent risk factors. The addition of LTA to HP lowered the probability of ITGM recurrence by a factor of 0.35 (p = 0.015), but the conversion from SG or OAGB to RYGB did not reduce the risk. CONCLUSIONS: LTA reduces the risk of early ITGM recurrence. The long-term durability, however, needs to be further investigated.

Hiatoplasty for Intrathoracic Gastric Migration Associated with One Anastomosis Gastric Bypass (OAGB).

PURPOSE: The standard of surgical correction of post-bariatric intrathoracic gastric migration (ITGM) is hiatal hernia repair, but little is known about its efficacy in patients with one anastomosis gastric bypass (OAGB). We present our experience. METHODS: This retrospective cohort study includes all patients with OAGB who had undergone hiatal hernia repair from 2014 to 2019. The primary outcome was recurrence of ITGM as diagnosed by computed tomography and gastroscopy. RESULTS: A total of 63 patients underwent hiatal hernia repair 2-54 months (median 13) after primary OAGB (40 patients) or concurrent with revisional OAGB after prior sleeve gastrectomy (23 patients). ITGM recurred in 48% of patients with hiatal repair after primary OAGB and in 91% of patients with concomitant hiatal repair. Recurrences were diagnosed after a median interval of 9 and 8.5 months, respectively. Thirty-six patients (57% of total number) required a revision, and a re-recurrence of ITGM was detected in 15 patients. The Cox regression analysis of all hiatal repairs showed that two variables significantly influenced the likelihood of ITGM recurrence: the length of the migrated pouch (hazard ratio 1.32; p = 0.016) and the type of repair. Combining hiatoplasty with ligamentum teres augmentation (LTA) and conversion to Roux-en-Y gastric bypass (RYGB) lowered the probability of ITGM recurrence (compared with stand-alone hiatoplasty; hazard ratio 0.21, p = 0.029). CONCLUSION: The outcome of hiatal repair in patients with OAGB is unsatisfactory. Stand-alone hiatoplasty is particularly ineffective. The combination of hiatoplasty with LTA and conversion to RYGB improves the early results, but the long-term durability needs to be tested.

The New Interest of Bariatric Surgeons in the Old Ligamentum Teres Hepatis.

The search for an operation that effectively prevents and treats intrathoracic gastric migration (ITGM) after bariatric surgery has revived a long-forgotten technique: ligamentum teres cardiopexy (LTC) by which a vascularized flap of the teres ligament is wrapped around the distal esophagus. The systematic search of publications in the English language revealed 4 studies (total number of patients 53) in the non-bariatric literature with an unsatisfactory resolution of GERD. There were 5 reports from the bariatric literature with small patient numbers (total 64) and a short follow-up (6-36 months). There were no objective signs of gastric remigration in 93% of investigated patients. Acknowledging the limitations of these preliminary reports, bariatric surgeons are encouraged to further investigate the potentials of LTC in their patients.

Buttressing hepaticojejunostomy's with hepatic round ligament flap may be beneficial.

BACKGROUND: Bile leaks and anastomotic strictures are important complications of hepaticojejunostomy (HJ). Evidence suggests that the use of hepatic round ligament (HRL) to buttress HJ may be beneficial. This study evaluates the feasibility of this approach. METHODS: HJs performed over 2 years (Jun 2014- May 2016), with HRL reinforcement, were analyzed. Operative outcomes measured included technical difficulty, blood loss, time necessary for flap harvest, and reinforcement of HJ. The postoperative outcomes measured were the presence of bile leak and anastomotic stricture. RESULTS: Forty-one patients (27 M: 14 F), aged 2-79 years, median age of61 years, underwent HJ with HRL buttress; 27 for periampullary/ head of the pancreas carcinoma; 4 for choledochal cysts; 4 for chronic pancreatitis; 3 for gallbladder carcinoma; 3 for benign biliary stricture. The time for harvesting HRL flaps and buttressing HJ was <10 minutes. No blood was lost during harvesting the flaps. One patient (2.5 %) had grade A leak following radical cholecystectomy, and structures were not observed during a median follow-up of 18 months (6 months to 2years). CONCLUSION: HRL-based buttressing of HJ can reduce the bile leak and/or stricture rate.

Application value of ligamentum teres hepatis approach in laparoscopic biliary reoperation / 中华消化外科杂志

Objective To investigate the application value of ligamentum teres hepatis approach in laparoscopic biliary reoperation.Methods The retrospective cohort study was conducted.The clinical data of 58 patients with recurrent hepatolithiasis who underwent laparoscopic biliary reoperation in the Chengdu Second People's Hospital were collected.There were 33 males and 25 females,aged from 31 to 85 years,with an average age of 54 years.Thirty-one of 58 patients who underwent laparoscopic biliary reoperation using ligamentum teres hepatis approach were divided into the ligamentum teres hepatis group,and 27 patients who underwent laparoscopic biliary reoperation using regular anatomy and positioning were divided into the regular operation group.Observation indicators:(1) intraoperative situations;(2) postoperative recovery;(3) follow-up.Follow-up using telephone interview and outpatient examination was performed to detect the recurrence of bile duct stone up to August 2018.Doppler ultrasonography of biliary tract was performed once at 3,6 and 12 months postoperatively and once at every 12 months after 1 year.Measurement data with normal distribution were represented as Mean±SD and comparison between groups was analyzed by the t test.Measurement data with skewed distribution were described as M (range) and comparison between groups was analyzed by rank sum test.Count data were analyzed using the four-grid table chi-square test or Fisher exact probability.Results (1) Intraoperative situations:all patients underwent successful laparoscopic biliary reoperation,without conversion to open surgery and perioperative death.During the intraoperative exploration,7,8,16 patients in the ligamentum teres hepatis group and 5,8,14 patients in the regular operation group were respectively found peritoneal omental adhesions,hilar omental adhesions and hilar intestinal adhesions.The operation time and volume of intraoperative blood loss were (125± 24) minutes,40 mL (range,15-100 mL) in the ligamentum teres hepatis group and (150 ± 36) minutes,55 mL (range,20-350 mL) in the regular operation group,respectively,with statistically significant differences between the two groups (t =-3.162,Z =-2.768,P＜0.05).The primary suture of bile duct,T-tube drainage and intraoperative stone removal were detected in 10,21,26 patients of ligamentum teres hepatis group and 9,18,23 patients of regular operation group,respectively,with no statistically significant difference between the two groups (x2 =0.008,0.019,P＞0.05).Postoperative residual biliary calculi were removed by choledochoscope through T-tube sinus in outpatient department after 8-week carrying T-tube.(2) Postoperative recovery:the time to initial anal exsufflation and duration of postoperative hospital stay were respectively (31 ± 7) hours,(7.2± 1.5) days in the ligamentum teres hepatis group and (35±10) hours,(7.1±1.3)days in the regular operation group,with no statistically significant difference between the two groups (t=-l.814,0.036,P＞0.05).(3) Follow-up:5 of 58 patients were lost to follow-up,including 3 in the ligamentum teres hepatis group and 2 in the regular operation group.Fifty-three patients were followed up for 6-40 months,with a median follow-up time of 28 months.No recurrence of bile duct stone was found in the ligamentum teres hepatis group.One patient in the regular operation group had recurrence of common bile duct stones at 36 months postoperatively and underwent endoscopic sphincterotomy stone.Conclusion Laparoscopic biliary reoperation for patients with recurrence of hepatolithiasis is a safe and effective method,and it can also quickly determine the location of common bile duct,with advantages of less blood loss and shorter operation time.
