Laparoscopic Inguinal Hernia Repair: A Review of 1,000 Cases.

Journal of Minimally Invasive Surgery.2013;16(2):21-25. doi:10.7602/jmis.2013.16.2.21

PURPOSE: We reviewed our data compiled prospectively for evaluation of post-operative complications and recurrence of laparoscopic inguinal hernia repair. METHODS: Among the 1000 patients (age, > or =20 years old) who were undergone laparoscopic inguinal hernia surgery from January 2007 to July 2011, the age, sex, location, hernia type, operation time, postoperative morbidity, and conversion of 992 patients were analyzed. RESULTS: Among 992 patients, 919 (92.6%) were male and the mean age was 54.2 years (range, 20~90). Operation times (m inutes) for unilateral and bilateral hernia were 40.0 and 53.4, respectively. Mean operation time (minutes) showed a decrease over time, as that for the first half of all cases was 43.5 and that for the second half was 39.7 (p<0.001). Seven cases of conversion (post-radical prostatectomy hernia=7) were recorded to TAPP (n=3) or IPOM (n=4) from TEP. Eleven cases of postoperative catheterization (1.1%), five cases of port site seroma (0.5%), one case of mesh removal due to infection, 24 cases of seroma/hematoma (2.4%), 26 cases of neuralgia (2.6%), and four cases of bleeding with a drop in hemoglobin of more than 3 mg% (0.4%) were also recorded. There were three cases of recurrence (0.35%) at the median follow-up of 46 months (range, 20 to 70 months). CONCLUSION: Laparoscopic inguinal hernia repair can be performed safely, with low rates of complication and recurrence. This technique achieves good results combined with the benefits of minimally invasive surgery. We should be cautious in order to avoid postoperative bleeding, especially in cases of TEP.

Jung Yeon LEE ; Young Hoon ROH ; Young Hoon KIM ; Hong Jo CHOI

Journal of Minimally Invasive Surgery.2013;16(2):15-20. doi:10.7602/jmis.2013.16.2.15

PURPOSE: Laparoscopic surgery has recently shown rapid development, and has been applied in most abdominal surgeries. It has also been adopted in hepatobiliary surgery, especially in the resection of liver tumors. Significant advantages of laparosopic surgery over the conventional open method have been reported, however, the safety of the surgical resection margin and radicality of the tumor resection remain to be clarified. This study was conducted in order to assess the feasibility and potential superiority of laparoscopic liver resection of hepatocellular tumors to open surgery. METHODS: This study included 76 patients who underwent liver resection for hepatocellular carcinoma at Dong-A University Hospital from January 2008 through June 2010. Of these 63 cases, 31 patients underwent laparoscopic resections and 33 underwent open liver resections. Both groups were confirmed as hepatocellular carcinoma by postoperative pathology and analyzed retrospectively. RESULTS: There were no statistically significant differences in preoperative parameters, such as age, height, body weight, Child Pugh score, ASA, and tumor size in both groups. There were no significant differences in operating time, duration of hospital stay, safety margins of surgical resection, postoperative complications, and rate of recurrence and occurrence of new lesions in both groups, however, better disease free survival was observed in the laparoscopic group (p=0.024). CONCLUSION: Findings of this study showed that the laparoscopic group had better results in free survival period than the open group. Conduct of larger scale prospective studies wound confirm the superiority of the laparoscopic liver resection to the conventional open procedure in patients with hepatocellular carcinoma. Findings of this study also suggest that assessment of the factors associated with the quality of life, such as degree of postoperative pain, and size of the incisional scar, and long term postoperative complications may play an additional role in favoring the laparoscopic liver resection. To elucidate the superiority of the laparoscopic liver resection to the conventional open method, conduct of study involving a larger study group and a longer prospective research period will be needed.

Technical Compensation for Hepatic Vein Injury during Robotic Single Site Cholecystectomy.

Jae Uk CHONG ; Myung Jae JUNG ; Chang Moo KANG

Journal of Minimally Invasive Surgery.2016;19(3):115-116. doi:10.7602/jmis.2016.19.3.115

This video describes an event that could occur during any cholecystectomy. To the best of our knowledge, this video is the first description of the technical compensation for hepatic vein injury during robotic single-site cholecystectomy (RSSC). A 61-year-old male with a 1.6 cm gallbladder stone sought to go through with RSSC. During dissection of gallbladder from the liver bed, the hepatic vein was unexpectedly exposed and injured. Using the angulated robotic needle holder, the injured hepatic vein was repaired with 5-0 prolene monofilament suture. Although there is a lack of EndoWrist movement in RSSC, suturing was feasible. The patient was discharged on the second postoperative day without complications. Incidental hepatic vein injury could be safely managed using RSSC and prevent the need for conversion to a conventional laparoscopic or open approach.

Clinical Effectiveness of Laparoscopic Adrenalectomy.

Ohjoon KWON ; Sang Kuon LEE ; Jaseong BAE

Journal of Minimally Invasive Surgery.2013;16(3):74-79.

PURPOSE: A laparoscopic approach, rather than conventional laparotomy, is the well-accepted first choice for excision of an adrenal or perinephric retroperitoneal mass. The purpose of this study was to investigate the factors that affect surgical outcomes and analyze the clinical effectiveness of this surgical treatment modality. METHODS: We conducted a retrospective analysis of 62 patients who underwent laparoscopic adrenalectomies from September 2007 to February 2013. These operations were performed by a single surgeon. Demographic characteristics, operative data, tumor characteristics, and surgical outcomes were analyzed. RESULTS: Of 62 patients, 21 were men and 41 were women. The mean operative time was 151.16+/-48.58 minutes and the mean amount of blood loss was 179.51+/-161.66 ml. There were two cases of metastatic adrenal tumors that were resected completely with prolonged survival. There was one case of recurrence during the postoperative period. Preoperatively, it was only a tumor measuring 3.5 cm without evidence of malignancy. Postoperative complications occurred in three patients. However, there was no case of conversion to laparotomy. Previous history of open abdominal operation did not affect post-operative outcomes. CONCLUSION: Laparoscopic approach for adrenal tumors is indicated regardless of its type or past history of abdominal surgery. Unless greater than 10 cm, relatively large tumors can be safely removed using this method. In particular, due to the possibility of malignant potential, aggressive surgical intervention is recommended for tumors measuring between 3 and 5 cm. Use of a laparoscopic approach is associated with low risk of surgical complication and the benefits outweigh the disadvantages.

Journal of Minimally Invasive Surgery.2013;16(3):69-73.

PURPOSE: The purpose of this study is to evaluate the outcome of laparoscopic (LA) vs. open appendectomy (OA) in children under 12 years old with perforated appendicitis. METHODS: We reviewed the medical files of 156 children who underwent LA (n=96), OA (n=59), and conversion (CO) (n=1), and compared duration of operation, length of hospital stay, incidence of wound infection, mechanical ileus, intra-abdominal abscess (IAA), and re-admission. RESULTS: Compared to OA, LA resulted in longer duration of operation (58.32+/-17.105 min vs. 44.27+/-18.735 min; p=0.001), but fewer wound infections (2.1% vs. 10.2%; p=0.054), and fewer cases of mechanical ileus (0% vs. 5.1%; p=0.053). No differences in the length of hospital stay (5.85+/-1.824 days vs. 6.10+/-3.027 days; p=0.526), IAA (2.1% vs. 1.7%; p=1.000), or re-admissions (2.1% vs. 5.1%; p=0.369) were observed. CONCLUSION: We report that although LA showed an association with longer duration of operation compared to OA, it is superior to OA with regard to incidence of wound infection and mechanical ileus.

Eun Young KIM ; Hyung Ook KIM ; Hung Dai KIM ; Jun Ho SHIN ; Byung Ho SON ; Won Joon CHOI

Journal of Minimally Invasive Surgery.2013;16(3):62-68.

PURPOSE: Acute appendicitis is a type of abdominal disease that requires emergency surgery. Over the past three decades, laparoscopic appendectomy has become the standard operation for acute appendicitis. The aim of this paper is to compare the methods of single port appendectomy and conventional appendectomy and to illustrate the advantages of single port appendectomy. METHODS: The first group of patients underwent single port appendectomy using a surgical glove (Group 1), and those in the second group underwent surgery using the TriPort system (Group 2). The third group of patients underwent conventional three port surgery (Group 3). Questionnaires regarding patient satisfaction with scars were administered via telephone interview. Patient characteristics, histopathological data, postoperative data, and satisfaction score were analyzed by t-test and Pearson chi2 test. RESULTS: A statistically significant difference in satisfaction scores was observed among the three groups. Overall, patients in the single port group using a surgical glove would be more likely to recommend the procedure to friends and family than would patients in the other two groups. Better cosmetic results were achieved for both groups of patients who underwent laparoscopic single port appendectomy, compared to those who underwent conventional three port laparoscopic appendectomy, with statistically significant difference. CONCLUSION: Laparoscopic single port appendectomy using a surgical glove is a feasible and safe procedure and shows no differences in terms of risk, such as postoperative complication, compared to a conventional three-trocar technique. Use of this method resulted in better satisfaction compared with the other two groups, illustrating its cosmetic improvement.

Comparison of Clinical Outcomes between the Hem-o-lok Clip and Endoloop Ligature in Securing the Base of the Appendix.

Young Chan KIM ; Tae Kyung HA

Journal of Minimally Invasive Surgery.2013;16(3):56-61.

PURPOSE: There are various techniques for securing the base of the appendix during performance of laparoscopic appendectomy. Many studies have reported that Endo-GIA is useful for securing the base of the appendix; however, it is costly. Many hospitals now use Endoloop ligature (ELL) for securing the base of the appendix. Many studies have demonstrated the many advantages of the Hem-o-lok clip (HLC) for securing the base of the appendix. The aim of this study is to compare the surgical outcomes of securing the base of the appendix between HLC and ELL during performance of laparoscopic appendectomy. METHODS: A retrospective cohort study was conducted for comparison between HLC and ELL for securing the base during performance of laparoscopic appendectomy. From May 2008 to October 2011, 102 patients underwent laparoscopic appendectomy performed by a single surgeon. Thirty one patients were excluded for various reasons. In 38 patients, the base of the appendix was secured by HLC, and in 33 patients, ELL was applied. Data included age, sex, body mass index (BMI), cost of materials, preoperative white blood count (preoperative WBC), preoperative c-reactive protein (preoperative CRP), preoperative fever, operation time, hospital days, diameter of the appendiceal base, number of perforated appendicitis, and intraoperative or postoperative complication. RESULTS: HLC was used in 38 patients, with a meanage of 36.4 years old. ELL was applied in 33 patients, with a meanage of 19.3 years old. Significant difference in age of patients was observed between the groups (p<0.001). The groups were comparable with regard to sex, BMI, preoperative WBC, preoperative CRP, preoperative fever, operation time, hospital stay, diameter of the appendiceal base, perforated appendicitis, and intraoperative or postoperative complication. The cost of six HLCs was 32,940 won, and that for one ELL was 29,610 won, therefore, there was no significant difference in the cost of material between the tw o groups of patients. CONCLUSION: Except for age, no difference was observed between the two groups. If a single HLC set is available for securing the base of the appendix, there will be a significant difference of the material cost between the two groups. ELL is more useful for securing the appendiceal base, with a larger diameter, which is inappropriate for use of HLC.

Jin Hyung BAE ; Ki Hoon JUNG ; Ho Geun JUNG ; Dong Yeop HA ; Jung Min BAE

Journal of Minimally Invasive Surgery.2013;16(3):52-55.

PURPOSE: Conventional laparoscopic appendectomy (LA) is a widely used treatment for appendicitis. Nowadays, single incision laparoscopic appendectomy (SILA) is increasingly used as an alternative treatment for appendicitis. The purpose of this study is to evaluate the clinical significance and differences between LA and SILA. METHODS: A total of 519 patients undergoing LA or SILA between January 2011 and December 2012 were identified in a retrospectively collected database. Patients' characteristics and peri-operative variables were analyzed. RESULTS: LA was performed in 485 patients and SILA was performed in 34 patients. Mean operation time for the LA group was 62.7 minutes (range 23.3~68.1) and that for the SILA group was 62.7 minutes (range 50.9~74.5). This difference of operation time was statistically significant. In the learning curve of SILA, operation time was gradually decreased. No significant differences in hospital stay and peri-operative complications were observed between groups. CONCLUSION: Although operation time for SILA was longer than that for LA, SILA was safe. Therefore, a prospective study should be conducted in order to confirm the possibility of application to most appendicitis patients.

Bowel Anastomosis in Single Port Laparoscopic Right Hemicolectomy: Comparison of Functional End to End Anastomosis and Isoperistaltic Side to Side Anastomosis.

Seong Hyeon YUN ; Seung Woo CHUNG ; Jung A YUN ; Yoon Ah PARK ; Jung Wook HUH ; Yong Beom CHO ; Hee Cheol KIM ; Woo Yong LEE

Journal of Minimally Invasive Surgery.2013;16(3):45-51.

PURPOSE: Colorectal surgeries by single port laparoscopic surgery (SPLS) are increasing. While recent studies have reported results that are similar with the idea of conventional laparoscopy, SPLS is considered superior to conventional laparoscopy with regard to cosmetic aspects. We investigated the question of whether length of incision and postoperative recovery are different depending on the method of anastomosis in patients who underw ent SPLS right hemicolectomy (RHC). METHODS: Data on patients who underwent SPLS RHC from May 2011 to April 2012 at Samsung Medical Center were retrospectively collected. Among 117 patients, 31 received functional end-to-end anastomosis (FEEA) while 86 received isoperistaltic side-to-side anastomosis (ISSA). RESULTS: Operation time was shorter in FEEA compared to ISSA (152+/-42 vs 172+/-35 min, p=0.01). Neither group required an additional port. Although wound extension for specimen delivery tended to be frequent in loop type specimen after FEEA, the result was statistically insignificant (58.1 vs 43.0%, p=0.15). No difference in wound length was observed (4.4+/-1.0 vs 4.5+/-1.5 cm). Length of stay was longer in ISSA compared to FEEA (6.3+/-2.1 vs 7.9+/-4.3 days, p=0.01), and there was no difference in first gas passage (2.5+/-0.9 vs 2.8+/-0.9 days, p=0.26). Although three patients (9.7%) with FEEA and 19 patients (22.1%) with ISSA had postoperative complications, the difference was insignificant. CONCLUSION: Theoretically, delivery of a tube shaped specimen after ISSA is expected to reduce unnecessary wound extension and possible tumor dissemination compared to loop shape specimen after FEEA. However, results of our study showed no advantage in recovery period and wound length. We suggest that future prospective study might reveal more valuable conclusions on the subject.

Jun Beom PARK ; Min Sang SONG ; Kyung Ha LEE ; Jin Soo KIM ; Ji Yeon KIM

Journal of Minimally Invasive Surgery.2013;16(3):39-44.

PURPOSE: Use of bipolar electocoagulation devices becomes popular in the laparoscopic surgical field. However, several studies comparing energy-based devices for use in performance of mechanical sealing and cutting techniques have reported various results. The aim of this study was to evaluate feasibility and efficacy of new commercially available bipolar electocoagulation devices: EnSeal(TM) device (Ethicon Endo-Surgery, Cincinnati, OH, USA) by comparison with LigaSure(TM) atlas 5 mm (COVIDIEN, Boulder, CO, USA), for use in performance of coagulation and cutting techniques during performance of laparoscopic colorectal cancer surgery. METHODS: Between June 2010 and February 2011, 50 consecutive patients who underwent curative laparoscopic surgery for right colon cancer or rectal cancer were enrolled. Time and number of device activations were compared during omentectomy in cases of right colectomy and mesorectal trimming procedure in cases of anterior resection. Pathologic data and short-term clinical outcomes were also compared. RESULTS: No significant differences in terms of clinicopathologic comparison were observed between the EnSeal and LigaSure groups. No significant difference in mean operative time (207.6+/-45.3 vs. 198.9+/-57.2; p=0.558), mean time of omentectomy (11.0+/-4.5 vs. 12.6+/-8.6; p=0.293), mean time of m esorectal trimming (18.6+/-10.0 vs. 16.1+/-6.9; p=0.418), mean number of device activations during omentectomy (43.5+/-10.2 vs. 51.6+/-39.2; p=0.586), and mean number of device activations during performance of mesorectal trimming (44.8+/-22.3 vs. 49.1+/-23.7; p=0.597) were observed between the two groups. CONCLUSION: Bipolar electocoagulation devices were adapted for use in laparoscopic surgery, resulting in reduced operative time and blood loss. EnSeal(TM) Device and LigaSure(TM) atlas 5 mm were useful during performance of sealing and cutting techniques in laparoscopic colorectal cancer surgery.
