Hand-assisted laparoscopic ultrasound-guided radiofrequency thermal ablation of liver tumors: a technical report

Ultrasound-guided radiofrequency thermal ablation has been performed for liver tumors by percutaneous, laparoscopic, or open surgical approaches. Each approach has specific advantages and disadvantages. Herein we describe a new technique for hand-assisted laparoscopic ultrasound-guided radiofrequency thermal ablation of liver tumors. A hand-access device is placed at the right or central portion of the abdomen, in addition to standard trocars. A conventional intraoperative ultrasound probe, with an ultrasound guidance system attached, is inserted into the peritoneal cavity together with the surgeon's hand. After pneumoperitoneum is established, an electrode-cannula for thermal ablation is introduced subcostally or intercostally, and advanced into a liver tumor under direct guidance by intraoperative ultrasound. We have used this technique in eight patients with unresectable liver tumors. Precise guidance of the cannula into tumors was possible. All tumors were well ablated. The postoperative recovery of patients was of shorter duration compared with that of an open surgical approach. A hand-assisted laparoscopic ultrasound-guided method has advantages of both laparoscopic and open surgical approaches for radiofrequency thermal ablation treatment of liver tumors. Accurate cannula insertion is possible with the ultrasound guidance system. The hand-assisted laparoscopic approach can become an additional useful technique, particularly as a valuable alternative to an open surgical method, for performing radiofrequency thermal ablation.     

Radiofrequency ablation with hand-assisted laparoscopic surgery for the treatment of hepatocellular carcinoma in the caudate lobe

OBJECTIVE: To assess the feasibility and safety of radiofrequency ablation (RFA) with hand-assisted laparoscopic surgery (HALS) for hepatocellular carcinoma (HCC) in the caudate lobe with severe liver dysfunction. SUMMARY BACKGROUND DATA: HCC in the caudate lobe remains one of the most difficult locations where various treatments tend to pose problems regarding the optimal surgical approach. The technique of HALS has thus been proposed as a useful method for performing a safe RFA therapy. For this study, we assessed the feasibility and safety of RFA with HALS for the treatment of HCC in the caudate lobe with liver dysfunction. PATIENTS AND METHODS: Between July 1999 and February 2005, 5 patients who suffered from HCC in the caudate lobe were indicated for RFA. The percutaneous puncture was difficult and all patients have severe liver dysfunction with viral chronic hepatitis. Therefore, RFA was assisted by an inserted hand through a minimal skin incision under laparoscopic inspection. An intraoperative endoscopic ultrasound examination was performed before RFA to determine the tumor region. The hand-assisted minimal dissection around the caudate lobe was required to detect tumor and avoid injuries of other tissues. RFA for HCC was performed using a cooled-tip (Radionics Inc, Burligton, MA) connected to a RF generator under the programmed cyclic impedance. RESULTS: The surgical procedures consisted of 5 RFA to tumors in the caudate lobe with HALS, which was performed safely, and a postoperative computed tomography scan revealed a sufficient ablation in all patients. There was no operative mortality but 1 patient had minor bile leakage, which was treated conservatively, and all patients recovered and thus were eventually discharged. One patient had local recurrence after 3 months, 3 patients had tumor recurrences in another segment after 6 months. At a mean follow-up 32.2 months, all patients were still alive. CONCLUSIONS: RFA with HALS is considered to be a safe and feasible technique for HCC in the caudate lobe with liver dysfunction.     

Hand-assisted laparoscopic distal pancreatectomy with minilaparotomy for distal pancreatic cystadenoma

Two patients with cystic tumors of the pancreas treated by laparoscopic distal pancreatectomy are presented. The first patient was a 34-year-old woman with a 6-cm cystadenoma of the tail of the pancreas treated with a complete laparoscopic distal pancreatectomy. After mobilization of the distal pancreas and spleen, the pancreas was transected proximally together with the splenic artery and vein using an endoscopic linear stapler. The second patient was a 71-year-old woman with a 6-cm cystadenoma of the body of the pancreas, treated by hand-assisted laparoscopic distal pancreatectomy with minilaparotomy because the tumor was adjacent to the portal vein and celiac axis. Using an upper median minilaparotomy, dissection of the gastrocolic ligament, division of the splenic artery, and transection and closure of the pancreas were performed. Division of the splenic vein and mobilization of the distal pancreas and spleen were performed via a hand-assisted laparoscopic approach. There were no postoperative complications (such as pancreatic fistulas) in either patient, and the postoperative courses were uneventful. The patients returned to normal activity within 1 week after the operation. Complete laparoscopic and hand-assisted laparoscopic distal pancreatectomy are preferable to conventional open surgery for benign tumors of the pancreas because of their less-invasive nature. Additionally, in tumors of the body of the pancreas, hand-assisted laparoscopic distal pancreatectomy might have the advantages of laparotomy and laparoscopy in terms of handling the splenic artery and vein just below the minilaparotomy site, suggesting an easier and safer procedure than complete laparoscopic distal pancreatectomy. Therefore, hand-assisted laparoscopic distal pancreatectomy can be recommended as a useful alternative to complete laparoscopic distal pancreatectomy for selected patients with benign tumors of the body and tail of the pancreas.     

Hand-assisted laparoscopic management of liver tumors

Background Laparoscopy has clearly advanced the treatment of many diseases related to the liver and biliary tree. The addition of hand assistance can further facilitate minimally invasive liver surgery by providing tactile feedback, atraumatic and versatile retraction, finger-fracture parenchyma dissection, and more precise placement of probes and staplers. Methods Over a 7-year period, 28 patients with liver tumors underwent 31 hand-assisted laparoscopic operations at a tertiary care center. The candidates for hand-assisted laparoscopic resection were patients with lesions involving two hepatic segments or fewer located at the inferior edge of the liver (segments 5 and 6), or confined to the left lateral segment (segments 2 and 3). Ablation was reserved for patients with poor functional status or limited hepatic reserve, and hand-assistance was added for laparoscopic ablation of centrally located tumors (segments 7, 8, and 4a). Results The selection criteria were met by 52 patients, 6 of whom had benign lesions. The remaining 46 patients had malignant disease, and 15 of these patients (33%) were found to have extrahepatic disease: 11 at initial laparoscopy and 4 at hand-assisted abdominal exploration. Manual exploration also detected additional intrahepatic treatable lesions in two cases. A total of 19 patients (68%) had metastatic disease, and 3 (11%) had primary liver cancer. The most extensive resections were five left lateral segmentectomies. All margins were negative. The mean operative time was 2.75 h, and the mean blood loss was 230 ml. Two diaphragmatic injuries occurred during ablation of segment 8 lesions. Three cases were converted to open surgery because of adhesions. The mean hospital stay was 3.7 days. A group of 15 patients who had metastatic colorectal cancer treated with resection and/or ablation had a mean follow-up period of 24 months (range, 2–61 months) and a mean survival time of 36 months. Conclusions For selected patients, the hand-assisted technique can be applied safely and effectively to laparoscopic liver surgery and may identify the presence of previously undetectable intrahepatic or extrahepatic disease.

The advantages of hand-assisted laparoscopy

The technical challenges of performing laparoscopic renal surgery require fellowship training and are associated with a steep learning curve. For the established urologist in practice, fellowship training is not a reality. As a result of these obstacles, in the late 1990s, laparoscopic renal surgery was entering the domain of the general surgeons who had a large number of laparoscopic procedures at their disposal to develop laparoscopic skills. Handassisted laparoscopic renal surgery is a hybrid procedure combining the most salient features of open renal surgery and laparoscopic renal surgery. By allowing the surgeons to place their non-dominant hand into the abdominal cavity, palpation and spatial orientation became possible, lessening the learning curve for laparoscopic surgery. Moreover, hand-assisted laparoscopic surgery could be applied to a variety of renal surgeries, extirpative and reconstructive, with results similar to those already achieved by standard laparoscopy. Throughout the past 5 years, hand-assisted laparoscopy has allowed urologists to incorporate laparoscopic renal surgery into their practices to the benefit of their patients and of their specialty. This review article offers a historical review of the development of hand-assisted laparoscopy and describes the procedures commonly performed today using this technique.     

Laparoscopic liver surgery for everyone: the hybrid method

Minimally invasive techniques have been described recently for liver resections. We have developed a surgical approach to liver resection that combines the benefits of minimally invasive surgery with the safety of open liver resection. We have applied this hybrid approach to selected cases, and we feel that it can be adopted by most hepatobiliary surgeons, even those with minimal or no laparoscopic experience. Briefly, this technique consists of laparoscopic mobilization of the target liver lobe, followed by standard open liver resection through the extraction site. The required incisions parallel those needed for hand-assisted laparoscopic liver resections. We have compared these hybrid procedures with contemporaneous laparoscopic, hand-assisted, and open liver resections at our institution and have found that they compare favorably with minimally invasive procedures. A wider utilization of this approach by both general and hepatobiliary surgeons will result in a more generalized acceptance of minimally invasive liver resection that ultimately will advance the field and benefit patients in need of liver surgery.

Advantages of laparoscope-assisted surgery for recurrent Crohn's disease

Background Laparoscopic surgery has been applied to patients with primary Crohn's disease, and its beneficial outcomes have been already investigated. However, there is no systematic study of laparoscopic surgery for patients with recurrent diseases. Methods We performed reoperation for 43 patients with recurrent Crohn's disease, including 23 patients who underwent laparoscope-assisted surgery. Results For all the patients, laparoscope-assisted surgery could be performed safely, even if the patients had been treated previously by open surgery or had undergone multiple abdominal procedures. Conversion to open or hand-assisted laparoscopic surgery was necessary for 16 patients (69.6%) because of dense adhesions (11 cases) or bulky tumor (5 cases). Importantly, even if the procedure was converted, the skin incision was significantly shorter than with open surgery, and postoperative recovery was faster, especially for the patients who underwent conversion to hand-assisted laparoscopic surgery. Conclusions Laparoscope-assisted surgery is feasible and advantageous in reoperation for patients with recurrent Crohn's disease.     

Hand-assisted laparoscopic hepatectomy for solid tumor in the posterior portion of the right lobe: initial experience

OBJECTIVE: To prove the feasibility of hand-assisted laparoscopic liver resection for tumors located in the posterior portion of the right hepatic lobe. SUMMARY BACKGROUND DATA: Use of laparoscopic liver resection remains limited due to problems with technique, especially when the tumor is located near the diaphragm, or in the posterior portion of the right lobe. METHODS: Between October 2001 and June 2002, a total of 7 patients with solid hepatic tumors involving the posterior portion of the right lobe of liver underwent hand-assisted laparoscopic hepatectomy with the HandPort system at our hospital. Surgical techniques used included CO2 pneumoperitoneum and the creation of a wound on the right upper quadrant of the abdomen for HandPort placement. The location of tumor and its transection margin were decided by laparoscopic ultrasound. The liver resection was performed using the Ultrashear without portal triad control, with the specimens obtained then placed in a bag and removed directly via the HandPort access. RESULTS: The 5 male and 2 female patients ranged in age from 41 to 76 years (mean 62.3 +/- 14.4). Surgical procedures included partial hepatectomy for 6 patients and segmentectomy for one, all successfully completed using a variant of the minimally invasive laparoscopic procedure without conversion to open surgery. The mean duration of the operation was 140.7 +/- 42.2 minutes (90-180). The blood loss during surgery was 257.1 +/- 159 mL (250-500), without any requirement for intraoperative or postoperative transfusion. Pathology revealed hemagioma (n = 2), colon cancer metastasis (n = 2), and hepatocellular carcinoma (n = 3). There were no deaths postoperatively, with 1 patient suffering bile leakage. Mean hospital stay was 5.3 +/- 1.3 days postsurgery. CONCLUSION: The results of this study suggest that laparoscopic liver resection using the HandPort system is feasible for selected patients with lesions in the posterior portion of the right hepatic lobe requiring limited resection. Individuals with small tumors may benefit; because a large abdominal incision is not required, the wound-related complication rate might be reduced.

Hand-assisted laparoscopic surgery

Hand-assisted laparoscopic surgery has been used to perform nephrectomies. This report contrasts the efficacy, postoperative morbidity, length of stay, analgesic use, and time to recovery for hand-assisted laparoscopic nephrectomy, to standard laparoscopic and open nephrectomy. The technique for hand-assisted laparoscopic nephrectomy used at two institutions is described. The results from these two institutions are contrasted to results in the literature for standard laparoscopic and open nephrectomy. Standard and hand-assisted laparoscopic nephrectomy seem similar in terms of efficacy of surgery, time of surgery, estimated blood loss, length of stay, and time to full recovery. The two laparoscopic techniques seem to show advantage over open surgery in respect to shorter hospital stay, faster full recovery, and less analgesic use. The operative time for the laparoscopic surgeries is longer than the open surgery operating time. Hand-assisted laparoscopic surgery seems to be equivalent to standard laparoscopy. As urologists around the world are trained in hand-assisted laparoscopic nephrectomy, a more refined look at these early results will be possible.

Assessment of risk for intra-abdominal adhesions at laparoscopy for urological tumors

PURPOSE: Abdominal wall adhesions at laparoscopy may predispose patients to access related injuries and increase the complexity of the procedure. We have observed concern from referring physicians regarding the safety of laparoscopy in patients who previously underwent surgery because of the risk of abdominal adhesions. To assess the risk of adhesions at laparoscopy a retrospective cohort study was performed. MATERIALS AND METHODS: All patients who underwent a transperitoneal urological laparoscopic procedure in a 6-year period at our institution were included in this study. A chart review was performed to obtain demographic/surgical data and identify preoperative risk factors for adhesions, such as previous abdominal or pelvic surgery, radiation and/or intra-abdominal inflammatory disease. Operative videotapes were reviewed to determine the presence and location of adhesions. Standard statistical analyses were performed. RESULTS: During the study period 127 patients underwent transperitoneal laparoscopy and videotapes on 82 (65%) were available for review. A total of 44 patients (54%) were identified with preoperative risk factors for adhesions (group 1), while 38 (46%) had no risk factors (group 2). The relative risk of adhesions was 1.34 (95% CI 0.89 to 2.01, p = 0.18) when risk factors were identified. There were no differences in the groups in patient age, operative time, access technique, conversion to open surgery or complications. Estimated blood loss was significantly higher in group 2, likely due to the preponderance of cytoreductive laparoscopic nephrectomy in this group. CONCLUSIONS: There was no difference in the risk of intra-abdominal adhesions in patients with and without identifiable preoperative risk factors. Preoperative risk factors for adhesions should not contraindicate the transperitoneal laparoscopic approach for urological oncology procedures.     

Hand-assisted laparoscopic liver resection: lessons from an initial experience

BACKGROUND: Recent innovations in laparoscopic instrumentation make routine resection of solid organs a clinical possibility. HYPOTHESIS: Hand-assisted laparoscopic liver resection is a safe and feasible procedure for solitary cancers requiring removal of 2 segments of liver or less. DESIGN AND PATIENTS: Eleven patients with liver tumors deemed technically resectable by laparoscopic techniques were subjected to laparoscopic evaluation and attempted hand-assisted laparoscopic resection between July 1998 and July 1999. During the same period, 230 patients underwent open liver resection. SETTING: Tertiary care referral center for liver cancer. MAIN OUTCOME MEASURES: Success of laparoscopic resection, reasons for conversion to open liver resection, blood loss, tumor clearance margin, complications, and length of hospital stay. RESULTS: Five patients underwent successful resection by the hand-assisted laparoscopic technique. Data from the 5 successful cases and the 6 aborted cases are presented to outline the issues and the lessons learned. CONCLUSIONS: In selected patients, hand-assisted laparoscopic liver resection can be safely performed and might have potential advantages over traditional liver resection if the tumor is limited to the left lateral segment or is at the margins of the liver.     

The Feasibility of Laparoscopic Cholecystectomy in Patients with Previous Abdominal Surgery

A retrospective study was carried in 1500 patients submitted to elective laparoscopic cholecystectomy to ascertain its feasibility in patients with previous abdominal surgery. In 411 patients (27.4%) previous infraumbilical intraperitoneal surgery had been performed, and 106 of them (7.06%) had 2 or more operations. Twenty five patients (1.66%) had previous supraumbilical intraperitoneal operations (colonic resection, hydatid liver cysts, gastrectomies, etc.) One of them had been operated 3 times. In this group of 25 patients the first trocar and pneumoperitoneum were performed by open laparoscopy. In 2 patients a Marlex mesh was present from previous surgery for supraumbilical hernias. Previous infraumbilical intraperitoneal surgery did not interfere with laparoscopic cholecystectomy, even in patients with several operations. There was no morbidity from Verres needle or trocars. In the 25 patients with supraumbilical intraperitoneal operations, laparoscopic cholecystectomy was completed in 22. In 3, adhesions prevented the visualization of the gallbladder and these patients were converted to an open procedure. In the 2 patients Marlex mesh prevented laparoscopic cholecystectomy because of adhesions to abdominal organs. We conclude that in most instances previous abdominal operations are no contraindication to laparoscopic cholecystectomy.

Applicability of laparoscopic surgery for colorectal disease

BACKGROUND: The advantages of laparoscopic colorectal surgery for selected patients have been well established. However, the applicability of laparoscopic surgery in the whole population of patients with colorectal disease is not well known. METHODS: A single-institution medical records review of 269 patients subjected to colorectal surgery was made. Of these, 206 open colorectal procedures were performed, and data were reviewed retrospectively. In addition, 63 patients were subjected to laparoscopy, and their data were recorded prospectively. An analysis of the existence of factors that contraindicate laparoscopic colorectal surgery was done. These factors were of two types: absolute (urgent intervention, severe cardiopulmonary disease, advanced liver cirrhosis, tumor invasion into adjacent organs, simultaneous major surgery) and relative (midrectal tumors, tumors in the transverse colon, bulky tumors, more than two previous infraumbilical operations, previous intestinal surgery, and previous peritonitis). RESULTS: Factors that could contraindicate the laparoscopic approach were found in 118 patients (44%). The most common were urgent intervention (40%), midrectal tumors (19%), locally advanced cancer (13%), previous intestinal surgery (13%), and tumors >10 cm (6%). We considered 25% of the contraindications to be absolute and 19% relative. Taking these exclusion criteria into consideration when selecting patients for laparoscopic surgery, the conversion rate in our initial laparoscopic series (63 cases) was 13%. CONCLUSION: The indication for laparoscopic surgery for patients with colorectal disease is superior to 60% (absolute 56%, relative 81%). When using appropriate selection criteria, the conversion rate may be maintained below 10%. Preoperative selection of patients with colorectal disease allows optimal use of the advantages of laparoscopic surgery.     

Simultaneous resection of colorectal cancer and liver metastases in the right lobe using pure laparoscopic surgery

It is now common to resect colorectal cancer by laparoscopic surgery. Hepatectomy has become a standard treatment for patients with colorectal cancer with resectable liver metastases. The resection of liver tumors can now be done partly by laparoscopic surgery. However, metastatic tumors in the right lobe are often difficult to resect laparoscopically. Furthermore, simultaneous resection of the colorectum and liver may also be difficult. In this study, we evaluated a new method to resect both colorectal cancer and liver metastases in the right lobe by laparoscopic surgery. Two cases are presented that underwent total laparoscopic resection of a right lobe tumor, associated with laparoscopic colorectal resection. The metastatic tumor in the right lobe was first resected in the left hemi-prone position. Then, the colorectal cancer was resected in the lithotomy position. The method for resecting the right lobe liver tumor and colorectal cancer was safe and feasible. The mean duration of surgery was 443.5 min, and the mean blood loss was 158 mL. The postoperative course was uneventful. In selected patients, laparoscopic hepatectomy for right lobe synchronous metastatic tumors can be safely performed simultaneously with colorectal surgery.     

手助式腹腔镜在肝脏切除中的价值

目的:探讨手助式腹腔镜肝切除术的安全性、可行性与临床价值。方法:回顾分析2004年9月至2009年12月为82例患者行选择性腹腔镜肝切除术的临床资料,其中手助式腹腔镜手术57例,传统腹腔镜手术25例。并选择25例同期常规开腹肝切除的患者,对比分析手助式、完全腹腔镜及开腹肝切除术的差异。结果:3组患者的年龄、性别、肝硬化表现、术前实验室检查和肿瘤大小差异无统计学意义。与传统腹腔镜肝脏手术相比,手助式腹腔镜肝脏手术的手术时间较长[(189.5±47.1)m in vs.(155.1±54.9)m in],中转开腹率较低(4.0%vs.5.2%)。两组术后肝功能、并发症发生率及死亡率差异无统计学意义。传统腹腔镜组饮食恢复较早[(1.6±1.3)d vs.(2.5±1.5)d],住院时间较短[(5.6±5.1)d vs.(8.8±1.8)d]。与传统开腹手术相比,手助式腹腔镜肝脏手术的手术时间较长[(189.5±47.1)m in vs.(138.5±54.3)m in],但术中出血、术后肝功能、死亡率、并发症发生率及术后住院时间差异均无统计学意义。手助式腹腔镜组的饮食恢复也较早[(2.5±1.5)d vs.(3.6±1.5)d]。结论:手助式腹腔镜肝脏手术安全可行,但并无足够的证据表明手助式腹腔镜肝脏手术优于传统开腹手术。外科医师应积极掌握传统腹腔镜肝脏手术的技巧,手助式腹腔镜肝脏手术更适于经验较少的腹腔镜外科医师对初级腹腔镜技能的学习。
