Laparoscopic Cholecystectomy: Incidental Carcinoma of the Gallbladder with Abdominal Wall and Axillary Node Metastasis

A case report is presented of intra-mural gallbladder carcinoma discovered incidentally after laparoscopic cholecystectomy who subsequently developed abdominal wall recurrence at the epigastric exit port, and axillary lymph node metastases. Possible preventative steps for tumour dissemination and a management plan if incidental carcinoma is diagnosed is discussed. The use of a non-porous retrieval bag, early recognition of the carcinoma and excision of the exit wound are advocated.     

Port site recurrences after laparoscopic cholecystectomy

Port site metastasis is a well-documented event after laparoscopic procedures in cancer patients. We summarize current epidemiological knowledge about the risk of this complication after laparoscopic/conventional cholecystectomy in patients with unexpected gallbladder cancer as well as other intraabdominal malignancies. We found 174 cases of port site metastasis after laparoscopic cholecystectomy and 12 recurrences in the surgical scar after converted or open cholecystectomy. A review of all case reports and its comparison with four international surveys show a 14% incidence of port site metastases 7 months after laparoscopic cholecystectomy for cancer. Similar numbers are available for open cholecystectomy. Our data suggest that abdominal wall metastases of gallbladder cancer are not a specific complication of laparoscopy. The long-term prognosis of patients with unknown gallbladder cancer however seems to be worsened by laparoscopy. The registry of the German Society of Surgery, which prospectively compares follow-up and prognosis of all cases of cholecystectomy, laparoscopic as well as open, in patients with incidental gallbladder cancer will definitively clarify whether laparoscopy affects the prognosis of patients with unsuspected gallbladder cancer.

Multiple port-site metastasis of incidental gallbladder carcinoma after laparoscopic cholecystectomy

Laparoscopic cholecystectomy is a surgical procedure of choice for benign gallbladder diseases. In about 1-2% of cases histopathological examination demonstrate incidental gallbladder cancer (GBCA). We report a case of a 61 year old woman who developed port site metastases after laparoscopic cholecystectomy for adenocarcinoma of the gallbladder. Metastases appeared on all four port sites. Review of literature regarding incidental GBCA an port site metastases was also performed. We conclude that the retrieval bag should be routinely used in laparoscopic cholecystectomy; the procedure should be performed with minimal trauma; in cases of incidental GB carcinoma, full thickness excision of the abdominal wall of the port sites demands additional studies; additional liver bed excision and local lymphadenectomy for T1b carcinoma are yet to be considered.     

Late-Type Recurrence at the Port Site of Unexpected Gallbladder Carcinoma After a Laparoscopic Cholecystectomy: Report of a Case

A 73-year-old woman had a laparoscopic cholecystectomy for unexpected gallbladder cancer and 9 days later underwent both a liver bed resection and lymph node dissection. Four years later, she underwent a further resection of a port site recurrence of gallbladder cancer and no other site of recurrence was observed. The seeding of cancer cells during the removal of the resected gallbladder might have caused this tumor. This case may show that the port site recurrence did not necessarily indicate an incurable stage of the disease. In addition, an excision of the recurrent tumor also appeared to eliminate the disease in the patient. Received: November 5, 1999 / Accepted: March 24, 2000     

Regional lymph node metastasis from port site implants after laparoscopic surgery

Although overall incidence of laparoscopic port site implants is decreasing, it remains problematic in patients with occult intraabdominal malignancy. Port-site metastases may themselves become the source of new metastases. A 42-year-old man underwent a laparoscopic cholecystectomy for cholelithiasis. One month later, he was diagnosed with a right colon cancer, for which a right colectomy was performed. Eleven months later, a CT scan showed nodules in the umbilicus (one of the original laparoscopic port sites) and behind the right rectus abdominis muscle, adjacent to the deep epigastric vessels. These sites were resected, and histopathology confirmed metastatic adenocarcinoma. The right deep epigastric nodule was reported to be lymph node–positive for metastatic adenocarcinoma. It is probable that dissemination of cancer cells to this lymph node occurred from the port site implants. Presence of metastasis in the lymph nodes draining the abdominal wall should be examined in all patients with port site implants.     

Radical Second Resection Provides Survival Benefit for Patients with T2 Gallbladder Carcinoma First Discovered after Laparoscopic Cholecystectomy

Port site recurrence or peritoneal seeding is a fatal complication following laparoscopic cholecystectomy for gallbladder carcinoma. The aims of this retrospective analysis were to determine the association of gallbladder perforation during laparoscopic cholecystectomy with port site/peritoneal recurrence and to determine the role of radical second resection in the management of gallbladder carcinoma first diagnosed after laparoscopic cholecystectomy. A total of 28 patients undergoing laparoscopic cholecystectomy for gallbladder carcinoma were analyzed, of whom 10 had a radical second resection. Five patients had recurrences; port site/peritoneum recurrence in 3 and distant metastasis in 2. The incidence of port site/peritoneal recurrence was higher in patients with gallbladder perforation (3/7, 43%) than in those without (0/21, 0%) (p = 0.011). The outcome after laparoscopic cholecystectomy was worse in 7 patients with gallbladder perforation (cumulative 5-year survival of 43%) than in those without (cumulative 5-year survival of 100%) (p <0.001). Among 13 patients with a pT2 tumor, the outcome after radical second resection (cumulative 5-year survival of 100%) was better than that after laparoscopic cholecystectomy alone (cumulative 5-year survival of 50%) (p = 0.039), although there was no survival benefit of radical second resection in the 15 patients with a pT1 tumor (p = 0.65). In conclusion, gallbladder perforation during laparoscopic cholecystectomy is associated with port site/peritoneal recurrence and worse patient survival. Radical second resection may be beneficial for patients with pT2 gallbladder carcinoma first discovered after laparoscopic cholecystectomy.     

Open versus laparoscopic cholecystectomy for gallbladder carcinoma

Laparoscopic surgery has replaced conventional open cholecystectomy for benign gallbladder disease. A major concern is how to handle gallbladder cancer in the laparoscopic era, since there are numerous case reports of port site metastases from gallbladder cancer after laparoscopic cholecystectomy. There are also many experimental studies favoring the opinion that the laparoscopic technique implies a higher risk of spreading malignant disease. This opinion has gained wide acceptance despite little previous clinical effort to determine the risk of tumor dissemination and the lack of comparisons between open and laparoscopic surgery. This report is a short summary of our own studies and present knowledge with special respect to the clinical aspects of the development and incidence of abdominal wall metastases. Among 270 patients with verified gallbladder carcinoma in whom 210 had open surgery and 60 a laparoscopic cholecystectomy, 12 patients (6.5%) in the open cholecystectomy group and 9 (15%) in the laparoscopic group developed incisional metastases. Although the sparse clinical documentation does not unavoidably mean that laparoscopic cholecystectomy has an increased risk of disseminating tumor cells, we recommend open surgery in cases of known or suspected gallbladder carcinoma.

Unexpected gallbladder cancer and laparoscopic surgery

Case histories of three patients who underwent laparoscopic cholecystectomy for unexpected gallbladder cancer are reviewed. Port-site recurrence was observed in two of them. In one patient whose abdominal wall recurrent tumor was excised, a new recurrence developed, but after the reexcision she is symptom-free 10 months after the last procedure. The surgeon has to be aware of the fact that the survival rate can be doubled in stage pT2 if cholecystectomy is followed by extended radical operation. Only gallbladder cancer in stage pT1 does not need further procedure, except for excision of port sites. In case of uncertain diagnosis preoperative frozen section is recommended. Port-site recurrence does not mean an incurable stage of the disease or a sign of diffuse metastases. Even after reexcision of abdominal wall metastasis patients might be free from other detectable recurrences.     

Port site recurrence of gallbladder cancer after laparoscopic surgery: two case reports of long-term survival

More than 100 patients with port site recurrence after laparoscopic procedures have been reported, and in most cases recurrence has had a fatal outcome. Two patients who survived port site recurrence of unexpected gallbladder cancer after laparoscopic cholecystectomy are reported. Abdominal wall excision was performed in one patient, and thermoradiotherapy was performed in the other. Both patients have remained free of disease during long-term follow-up (82 and 45 months).     

Unsuspected gallbladder carcinoma--the CAE-S/CAMIC registry

INTRODUCTION: Results of earlier surveys raised the prospect that laparoscopic surgical procedures may specifically increase the risk of port wound metastasis and generally of tumour cell seeding if at the time of operation an unsuspected gallbladder cancer existed. Other observations lead to presume that laparoscopic technique could deteriorate the prognosis of gallbladder cancer. These assumptions are going to be verified by the CAES/ CAMIC-registry. MATERIAL AND METHOD: The Workgroup Surgical Endoscopy (CAE) of the German Society of Surgery has started 1997 a registry of all cases of cholecystectomy--laparoscopic as well open--with a postoperative incidental finding of a gallbladder carcinoma. The aim of our registry is to compare the prospectively collected follow up data on the outcome of these patients and to answer the question whether laparoscopic cholecystectomy affects the course and the prognosis of patients with unsuspected gallbladder cancer. RESULTS: Until now 142 cases of incidental gallbladder cancer following laparoscopic and 79 cases following open cholecystectomy as well as 24 cases after intraoperative conversion to the open procedure have been recorded. The median follow up runs up to 27 (1-69) months. Following laparoscopic primary procedure we registered 10 port site metastases (7 %), following open primary procedure 4 (5.1 %) wound recurrences. The total recurrence rate at the moment is about 27 % after laparoscopic treatment and 31 % for conventionally operated patients. 70 of the 245 patients underwent a second radical procedure after diagnosis of gallbladder carcinoma. A postoperative combined radio- and chemotherapy was undertaken in 4 cases, a chemotherapy alone in 14 cases. 64 patients already died due to the underlining disease. DISCUSSION: At the present, after a median follow up of 27 months, the incidence of abdominal wall recurrences is very similar following laparoscopic and conventional procedure (7 % vs. 5.1 %). The total incidence of recurrences is at the moment slightly higher following open cholecystectomy (31 % vs. 27 %). The access technique, open or laparoscopic, doesn't seem to influence the prognosis of unsuspected gallbladder carcinoma. Until now we could not find disadvantages for the laparoscopically operated group.     

Wound recurrence from gallbladder cancer after open cholecystectomy

BACKGROUND: Reports of port site recurrences from gallbladder cancer after laparoscopic cholecystectomy have raised considerable concern as to whether the laparoscopic technique implies an increased risk of metastatic disease. In a previous study of gallbladder cancer and laparoscopic cholecystectomy, we reported a frequency of 16% port site metastases. The purpose of the present study was to determine the frequency of wound metastases from gallbladder cancer after open cholecystectomy. METHODS: The registers from the Swedish Oncological Centers and the National Board of Health and Welfare were checked for reported cases of gallbladder cancer and surgical classification codes for open cholecystectomy from 1991 to 1994. The study included all 8 university and 24 county hospitals in Sweden. The files from all patients with gallbladder cancer who had an open cholecystectomy were retrospectively reviewed. RESULTS: The study included 270 patients who had a cholecystectomy, of which 215 were classified as open and 55 as laparoscopic. Of the 215 patients, 11 patients were excluded because of an incorrect or deficient histopathologic or surgical classification. In 186 patients (91%), sufficient data were obtained for follow-up. Twelve patients (6.5%) had wound metastases from their gallbladder cancer. All patients with wound metastases died with a median survival of 10 months (range, 3 to 65 months). CONCLUSIONS: Wound metastases from gallbladder cancer after open cholecystectomy may be more common than previously assumed.     

Port site recurrence of unexpected gallbladder carcinoma after a laparoscopic cholecystectomy: Report of a case

Unexpected gallbladder carcinoma was identified in a 71-year-old woman after she underwent a laparoscopic cholecystectomy (LC) for symptomatic cholelithiasis. A subsequent laparotomy for a resection of the liver bed and a dissection of the lymph nodes around the hepatoduodenal ligament was done. Two and a half years later, the patient developed subcutaneous metastasis at the epigastric trocar site through which the gallbladder was removed. A third operation was thus performed, revealing no evidence of peritoneal dissemination, liver metastasis, or lymph node metastasis, and the abdominal wall mass was resected. The histological findings confirmed the diagnosis of metastatic carcinoma of the gallbladder. We recommend that when planning LC, the possibility of malignancy should thus be kept in mind. However, if there is any sign which does not completely exclude malignancy, such as a contracture or wall thickness of the gallbladder, LC should be performed by the abdominal wall lifting method and using a protective bag for the removal of the gallbladder.     

How to proceed in patients with carcinoma detected after laparoscopic cholecystectomy

Carcinoma of the gallbladder is a rare disease. Gallbladder carcinoma is detected in less than 1% of all gallstone operations. With the introduction of laparoscopic surgery and the higher acceptance of this technique, gallbladders are now removed much earlier than they used to be. With the increase of cholecystectomies, the diagnosis of unexpected gallbladder carcinoma became more frequent. We report on how to proceed in patients with a diagnosis of gallbladder carcinoma and discuss the additional problems that have arisen since laparoscopic cholecystectomy became established. From June 1990 to December 1999, we performed 6230 cholecystectomies in the surgical department of Moabit Hospital in Berlin. Of these, 42 (0.6%) were identified as carcinoma. There were 37 women and five men, and the mean age was 69 years. In 16 patients (39%), there was a preoperative suspicion of malignancy. In 26 patients (61%), malignancy was suspected intraoperatively or diagnosed postoperatively after pathologic examination of the resected gallbladder. In these patients, an open repeat operation was necessary in seven cases to achieve an adequate curative resection and staging. This involved additional liver bed resection and lymph node dissection of the hepatoduodenal ligament. Abdominal wall (port site) recurrence in the absence of distant metastasis was present only in two patients. We recommend removal using a bag in all gallbladders with wall thickening, irregularities, or scleroatrophic calcified gallbladder area. In stage Tis or T1, laparoscopic cholecystectomy is sufficient. In stage T2 and T3, we perform a repeat operation with liver bed resection and lymphadenectomy.     

Laparoscopic cancer surgery

Laparoscopic cholecystectomy (LC) may inhibit the discovery of unsuspected gallbladder cancer, and the effect of LC on the prognosis of gallbladder cancer is unknown. We present two cases of unsuspected gallbladder cancer removed laparoscopically and report the discovery of peritoneal tumor implantation at the umbilical port site 21 days after LC.Although gallbladder carcinoma flow cytometry has been reported to be of prognostic value by Japanese investigators, this technique did not distinguish herein between an invasive adenocarcinoma and carcinoma in situ. A cellular doubling time of 56 h was calculated from one tumor.When unsuspected invasive gallbladder cancer is found after LC, laparoscopic port sites should be inspected at reoperation and, at a minimum, the port site through which the gallbladder was removed should be widely excised. This demonstration of cancer recurrence in laparoscopic port sites may limit the application of laparoscopy to elective cancer resection.The views expressed in this paper are those of the authors and should not be construed to reflect the official positions of either the U.S. Air Force medical department or Saint Louis University     

Hepatic metastasis after laparoscopic cholecystectomy for polypoid gallbladder cancer followed by radical surgery

While laparoscopic cholecystectomy is being increasingly performed on patients with gallbladder disease, this approach in cases of polypoid lesions in the gallbladder may not always be justified. We report here a case of early development of intrahepatic metastasis after laparoscopic cholecystectomy for polypoid gallbladder cancer; wedge resection of the gallbladder bed and dissection of regional lymph nodes had to be done. When a malignancy of the gallbladder is suspected during preoperative examinations, open cholecystectomy should be done.     

Port site metastases from gallbladder cancer after laparoscopic cholecystectomy. Results of a Swedish survey and review of published reports.

OBJECTIVE: To investigate the incidence of port site metastases from unsuspected gallbladder cancer after laparoscopic cholecystectomy. DESIGN: Retrospective national multicentre study, 1991-94. SETTING: All 8 university and 24 central hospital, Sweden. SUBJECTS AND INTERVENTIONS: All 32 hospitals were interviewed by means of a written questionnaire. The registers of all Swedish Oncological Centres and the registers of the National Board of Health and Welfare were checked for reported cases of gallbladder cancer and surgical classification codes for cholecystectomy. To detect laparoscopic interventions incorrectly registered as open operations, all cholecystectomies registered as open were matched against the Swedish Registry of Laparoscopic Cholecystectomy for the years 1991-93 and all patients records for 1994 were scrutinised. RESULTS: Replies were obtained from 30/32 clinics (94%) and 11976 laparoscopic cholecystectomies were done. Of 447 patients with verified gallbladder carcinoma 270 had their gallbladders removed, 55 (20%) laparoscopically. 9 of these (16%) developed port site metastases and 6 died from their disease at a median of 18 months (range 5-22). Two patients are alive, 54 and 45 months after cholecystectomy. One patient has been lost to follow-up. CONCLUSIONS: Port site metastases from gallbladder cancer may be more common than previously thought. A laparoscopic procedure should not be done if cancer of the gallbladder is suspected.     

Port-sites excision for gallbladder cancer incidentally found after laparoscopic cholecystectomy

Port-site recurrence represents a severe complication in the case of incidental gallbladder cancer (ICG) discovered after laparoscopic cholecystectomy, and is reported to occur in 17% of cases. For this reason port-sites excision is an essential surgical step during the second operation, which includes liver resection (segments 4b and 5) and lymph node dissection (hepatic pedicle and retroduodeno-pancreatic region). In this article we describe a simple technique to obtain a radical port-site excision with the aim to standardize this surgical step and to perform it in a radical way. Port-sites excision is the accurate and complete excision of the parietal channel created by the trocar during the previous cholecystectomy. This channel is often Z-shaped. In the second operation, the presence of peritoneal adhesions helps to identify exactly the previous site of entry of the trocar in the peritoneal cavity. Trocar reinsertion through the abdominal wall along the correctly identified original path allows the excision of a perfect cylinder of abdominal wall including all of the layers from the skin to the peritoneum.     

Gallbladder metastases from ductal papillary carcinoma of the breast

Breast cancer occurs primarily in women aged 25 years or older. Breast carcinoma has the potential for widespread dissemination, such as metastasis to axillary lymph nodes, bone, lung, pleura, brain, and soft tissues. Liver, gastrointestinal, and biliary tract involvement are infrequent. We report a patient, a 62-year-old woman, with symptomatic cholelithiasis. The patient proceeded to laparoscopic cholecystectomy. She had a previous history of mastectomy with axillary lymphadenectomy, performed for a breast ductal papillary carcinoma, 10 years prior to the cholecystectomy. The gallbladder was hydropic; the wall was thickened, with a focal broad-based lesion on the mesenteric face of the body. Histopathological evaluation of the focal broad-based lesion of the gallbladder revealed poorly differentiated adenocarcinoma infiltration, without mucosal involvement. Subsequent immunohistochemical examination showed the lesion to be cytokeratin 7(CK7)-positive and cytokeratin 20 (CK20)-negative. Estrogen receptor (ER) and progesterone receptor (PgR) were positive. The final pathological diagnosis was breast ductal papillary carcinoma metastases to the gallbladder. Mammography of the other breast was normal. Computed tomography (CT) scan of the brain, chest, abdomen, and pelvis was performed, without any pathological findings. Bone Tc-99 scintigraphy was normal. Six months after the surgery positron emission tomography (PET) showed no evidence of metastatic disease. Two years after the surgery, the patient died, in the absence of recurrence. A literature review revealed only a few more cases of metastasic breast carcinoma to the gallbladder.     

Long-term prognosis of gallbladder cancer diagnosed after laparoscopic cholecystectomy

BACKGROUND: Several clinical and laboratory studies concerning port-site recurrence have raised the concern that laparoscopic procedures might worsen the prognosis of malignant disease. However, the long-term prognosis of patients with malignancy who undergo laparoscopic surgery is still unknown. The purpose of this study was to examine the long-term prognosis of patients with unexpected gallbladder cancer diagnosed after laparoscopic cholecystectomy (LC). METHODS: A clinicopathologic study was performed on 41 patients with postoperatively diagnosed gallbladder cancer from among 5,027 patients undergoing LC at 24 institutions. The cumulative survival rate was compared with that reported for gallbladder cancer diagnosed after open cholecystectomy (OC). RESULTS: Of 26 patients with early gallbladder cancer (pTis or pT1), 23 were simply followed up, and 9 of 15 patients with advanced cancer (pT2 or pT3) had additional resection after the diagnosis of gallbladder cancer. Port-site recurrence occurred in four patients, and two of them died of the cancer. However, at this writing, the other two are still alive after abdominal wall resection or radiation therapy, having survived for 31 and 71 months, respectively. The 5-year survival rate was 92% for early cancer and 59% for advanced cancer. These results were comparable with 5-year survival rates for gallbladder cancer diagnosed after OC. CONCLUSIONS: Although port-site recurrence occurred in four patients with advanced gallbladder cancer, the long-term prognosis of patients with undiagnosed gallbladder cancer who underwent LC was not worsened by the laparoscopic procedure. We conclude that surgeons can perform LC with reasonable confidence, even if the lesion is possibly malignant.     

Gallbladder carcinoma during laparoscopic cholecystectomy: is it associated with bad prognosis?

Laparoscopic cholecystectomy is the treatment of choice for gallstone disease. The ultrasonogram has failed for the early detection of gallbladder cancer, especially if inflammation (chronic or acute) is present. Incidental gallbladder could be an important cancer finding during laparoscopic cholecystectomy, due to the potential cancer cell dissemination during the procedure. In our Department, 6500 laparoscopic cholecystectomies have been performed in the last 5 years and in 15 cases (0.23%) gallbladder cancer was found during surgery or after histological examination of the resected gallbladder. In none of these 15 patients was pre-operative diagnosis of gallbladder carcinoma postulated. When re-evaluation of the pre-operative ultrasonograms was done, it was possible to observe signs suggesting the presence of neoplastic infiltration in 4 of them (28.6%). During videoscopic exploration, also in 4 patients, the suspicion of gallbladder cancer was noted. Laparoscopic cholecystectomy was completed in 9 patients. In 2 of them, in situ or mucosal invasion was demonstrated with a long survival. One patient presented recurrence at the biliary hilum 2,5 years after surgery. Six patients were re-operated and in 4 of them peritoneal or port site metastasis was found; all died early (4.5 month median survival). The other 2 patients were submitted to liver bed resection and lymph node dissection. These patients are free of cancer recurrence after 15 months of follow-up. Six patients were converted to open surgery, performing palliative procedures and died before the 12 month follow-up. The suspicion of pre-operative gallbladder cancer is generally unlikely to be confirmed based on ultrasonographic signs; but, in some cases with high suspicion, further investigation (TAC, tumor markers, etc.) must be indicated in order to avoid poor results. Laparoscopic cholecystectomy could be associated with bad prognosis, and then, when gallbladder cancer is suspected during the laparoscopic procedure, conversion to open surgery could be the best choice.
