RESUMO
BACKGROUND: Robotic-assisted laparoscopic surgery (RALS) has become a widely and increasingly used modality of minimally invasive surgery in the treatment of endometrial cancer (EC). Due to its technical advantages, RALS offers benefits, such as a lower rate of conversions compared to conventional laparoscopy (CLS). Yet, data on long-term oncological outcomes after RALS is scarce and based on retrospective cohort studies only. OBJECTIVES: This study aimed to assess overall survival (OS), progression-free survival (PFS), and long-term surgical complications in EC patients randomly assigned to RALS or CLS. STUDY DESIGN: This randomized controlled trial was conducted at the Department of Gynecology and Obstetrics of Tampere University Hospital, Finland. Between 2010 and 2013, 101 patients with low-grade EC scheduled for minimally invasive surgery were randomized preoperatively 1:1 either to RALS or CLS. All patients underwent laparoscopic hysterectomy, bilateral salpingo-oophorectomy, and pelvic lymphadenectomy. A total of 97 patients (49 in the RALS group and 48 in the CLS group) were followed up for a minimum of 10 years. Survival was analyzed using Kaplan-Meier curves, log-rank test, and Cox proportional hazard models. Binary logistic regression analysis was used to analyze risk factors for trocar site hernia. RESULTS: In the multivariable regression analysis, OS was favorable in the RALS group (HR 0.39; 95% CI, 0.15-0.99, p=.047) compared to the CLS group. There was no difference in PFS (log-rank test, p=.598). The three-, 5- and 10-year OS were 98.0% (95% CI, 94.0-100) vs. 97.9% (93.8-100), 91.8% (84.2-99.4) vs. 93.7% (86.8-100), and 75.5% (64.5-87.5) vs. 85.4% (75.4-95.4) in the CLS and the RALS group, respectively. Trocar site hernia developed more often in the RALS group compared to the CLS group 18.2% vs. 4.1% (OR 5.42, 95% CI, 1.11-26.59, p=.028). The incidence of lymphocele, lymphedema, or other long-term complications did not differ between the groups. CONCLUSIONS: The results of this RCT suggest a minor OS benefit in EC after RALS compared to CLS. Hence, the use of RALS in the treatment of EC seems safe, but larger RCTs are needed to confirm the potential survival benefit of RALS. No alarming safety signals were detected in the RALS group since the rate of long-term complications differed only in the incidence of trocar site hernia.
RESUMO
BACKGROUND: Laparoscopy is common in abdominal surgery. Trocar site hernia (TSH) is a most likely underestimated complication. Among risk factors, obesity, the use of larger trocars and the umbilical trocar site has been described. In a previous study, CT scan in the prone position was found to be a reliable method for the detection of TSH following gastric bypass (LRYGB). In the present study, our aim was to examine the incidence of TSH after gastric sleeve, and further to investigate the proportion of symptomatic trocar site hernias. METHODS: Seventy-nine patients subjected to laparoscopic gastric sleeve in 2011-2016 were examined using CT in the prone position upon a ring. Symptoms of TSH were assessed using a digital survey. RESULTS: The incidence of trocar site hernia was 17 out of 79 (21.5%), all at the umbilical trocar site. The mean follow-up time was 37 months. There was no significant correlation between patient symptoms and a TSH. CONCLUSIONS: The incidence of TSH is high after laparoscopic gastric sleeve, a finding in line with several recent studies as well as with our first trial on trocar site hernia after LRYGB. Up to follow-up, none of the patients had been subjected to hernia repair. Although the consequence of a trocar site hernia can be serious, the proportion of symptomatic TSH needs to be more clarified.

OBJECTIVE: Easy and safe methods of fascia closure are needed in order to reduce the risk for trocar site hernias without affecting procedure time significantly. Here we present a method for port site closure using heat induced collagen denaturation. MATERIAL AND METHODS: Controlled heat-induced collagen denaturation was applied to laparoscopic trocar sites in living porcine animal models. These were compared to control trocar sites which were left open. Port sites were evaluated visually at days 14 and 28 after the procedure, and both visually and pathologically at post-procedural day 42. RESULTS: A total of 12 port sites were evaluated in three pigs. No incisional hernias were noted at any of the trocar sites in both groups. Histological evaluation revealed that one of the six control ports appeared to have a complete transfascial defect, whereas none of the study group trocars showed this finding. Furthermore, the study port sites showed a more robust scarring pattern. CONCLUSIONS: Heat-induced collagen denaturation in this preliminary study was found to be safe and allowed better scarring of the healing port sites. We believe that this technology may offer a safe and efficient closure of laparoscopic trocar sites. More studies are needed to further evaluate the true effectiveness of this technology.

PURPOSE: One of the complications in laparoscopic surgery is port-site hernia. It is a rare but potentially dangerous complication. Especially when using ports with a size 10 mm or more, it is required to securely close the port site. However, this procedure is often difficult especially for obese patients. METHODS: We herein devised a new closure method by using a device developed for port site. These techniques are methods that can close the port site by a combination of putting in and out of thread and port rotation without removing a port. The port-site closure with these techniques was done for 53 port sites of 41 patients. RESULTS: The port site was closed horizontally or vertically, depending on the shape of the port site for two patients. Modified Z-suture was done for other 37 patients. To date, we have not noted any complications from this new method, including port-site hernia. CONCLUSION: With our technique, we could save operation time and reduce stress of us especially for obese patients. We would like to increase the number of patients and verify the safety and usefulness in further study.

BACKGROUND: Since the introduction of laparoscopic surgery, it has become more popular with many advantages over open surgery including faster recovery, shorter hospital stays, and decreased tissue trauma. Despite its benefits, laparoscopic surgery can result in its own unique complications, such as the formation of a trocar site hernia (TSH), which have been reported in approximately 0-1.0% of laparoscopic cases when using non-bladed trocars. METHODS: A literature review was performed from June 1990 to June 2019. PubMed was searched using the keywords "laparoscopic surgery," "trocar site hernia," and "port site hernia." Only articles in English were identified but not limited to the USA. RESULTS: The total number of patients in all articles was 18,533 with a mean follow-up period of 22.50 ± 1.76 months. The overall trocar site hernia rate was 0.104%. When comparing open vs. closed ports, there was no significant difference in the hernia incidence rate for 5-mm and 10-mm ports. When comparing bladed versus non-bladed trocars left open, there was a statistically significant difference with lower hernia incidence rates for non-bladed trocars over bladed trocars for 5-mm, 10-mm, and 12-mm ports. And when comparing trocar location from midline versus off-midline, there was a statistically significant higher TSH incidence in midline trocar locations. CONCLUSION: Results suggest that TSH rate is lower when using non-bladed trocars for any size of trocar. When comparing whether fascial closure had an effect, the 5-mm and 10-mm ports had no difference in incidence rates and leaving the fascia open can reduce operative time, risk of needlestick injuries, and overall procedural cost. In addition, trocars at midline locations resulted in higher TSH incidence rates. Future research is still needed to assess for other factors that may influence hernia formation and how it can be minimized.

BACKGROUND: Prophylactic mesh closure has only scarcely been studied to avoid extraction-site incisional hernia after laparoscopic colorectal surgery. The aim was to analyze extraction-site incisional hernia incidence after laparoscopic colorectal surgery to assess if prophylactic mesh closure should be studied. METHODS: A retrospective analytic cohort study was conducted in patients who had undergone laparoscopic colorectal surgery with an extraction-site incision. Extraction-site incisional hernia was diagnosed during clinical examination or imaging. Risk factors for extraction-site incisional hernia were analyzed. RESULTS: Two hundred and twenty-five patients were included. More than 80% of the patients had a malignant disease. Ninety-two patients (40.9%) underwent right colectomy. Midline extraction-site incision was used in 86 (38.2%) patients. After a mean follow-up of 2.4 years, 39 (17.3%) patients developed an extraction-site incisional hernia. Midline extraction-site incision was associated with incisional hernia when compared to transverse and Pfannenstiel incision (39.5% vs. 3.6%, OR 17.5, p < 0.001). Surgery to repair an extraction-site incisional hernia was also more frequent in the group of patients with a midline incision (10.5% vs. 1.4%, OR 8.0, p = 0.002). In the multivariate analysis, incisional hernia was associated with body mass index, high blood pressure, and midline incision. CONCLUSIONS: Extraction-site incisional hernia was mainly related to midline incisions; therefore, midline incision should be avoided whenever possible. Studying prophylactic mesh closure for Pfannesnstiel or transverse incisions is needless, as these incisions have a low incisional hernia risk.

BACKGROUND: With the increasing use of the robotic platform in general surgery, whether 8-mm ports should be closed comes into question. We sought to characterize the incidence of port-site hernias (PSHs) among patients undergoing robotic-assisted general surgery. METHODS: A retrospective chart review of a single institutional database identified patients who underwent robotic-assisted general surgery from July 2010 to December 2016. For each patient, the number, type, location, and size of all ports were collected. Twelve-millimeter port sites were routinely closed, whereas 5-mm and 8-mm port sites were not. PSH was detected on review of documented physical examination and of postoperative cross-sectional imaging, when available, in which case it was defined as a disruption of the fascia with or without eventration of tissue at a site of prior port placement. RESULTS: One hundred and seventy-eight patients underwent robotic-assisted general surgery, with 725 total ports: 433 8-mm working ports, 72 12-mm working ports, 178 12-mm camera ports, and 42 5-mm assistant ports. Ninety-four percent of the patients were men, the mean age was 63 ± 12, body mass index was 29 ± 7 kg/m2, and the median American Society of Anesthesiologists score was 3. Types of cases included 68 rectal (38.2%), 36 colon (20.2%), 25 hepatopancreatobiliary (14.0%), 21 inguinal hernia (11.8%), and 28 "other" (15.7%) operations. At a median follow-up of 193 d, there were three PSHs through 8-mm port sites (0.7%), two PSHs through 12-mm port sites (0.8%), and no PSH through 5-mm port sites. Two of the three 8-mm PSHs occurred in the early postoperative period and required emergent repair due to small bowel incarceration. CONCLUSIONS: PSHs through 8-mm robotic port sites occur infrequently but can cause significant morbidity. Further investigation with longer follow-up is warranted to better understand the true incidence of robotic PSH.

AIM: To access the incidence and predictive factors of incisional hernia after single-incision laparoscopic cholecystectomy (SILC). METHODS: Eighty-two consecutive patients operated on for uncomplicated cholelithiasis between 2009 and 2013 were eligible for the study. Clinical outcome was assessed by a combination of case notes review, office consultation and telephone interview. Long-term incisional hernia rate was the major outcome of the study. Secondary outcome was the evaluation of predictive factors. Univariate and multivariate statistical analyses were performed using the following variables: age, gender, ASA score, BMI, risk, or comorbidity factors and surgical site infection. RESULTS: Six patients (7 %) were lost to follow-up after the 1-month office visit and excluded. The study group consisted of 16 men and 60 women with a median age of 42 years (range 18-69) and a BMI of 25 (range 19-34). Eight patients had risk or comorbidity factors, 46 were classified ASA I, and 30 ASA II. Early postoperative course was uneventful in all cases but two patients developed a superficial wound abscess after hospital discharge. With a median follow-up of 44 months (range 12-72), incisional hernia was noted in six patients (7.9 %). Multivariate logistic analysis revealed that age (OR 1.08, 95 % CI 1.00-1.16, p < 0.038) and BMI (OR 1.37, 95 % CI 1.03-1.82, p < 0.029) were independent predictive factors of developing an incisional hernia. The incidence of hernia was, respectively, 15 % in patients with an age ≥ 50 and 33 % in patients with a BMI ≥ 30. CONCLUSION: After SILC, we noted an incisional hernia rate of 8 %. To decrease the risk of developing that specific complication, SILC should only be proposed to young and non-obese patients.

BACKGROUND: Conventional laparoscopic cholecystectomy (CLC) is regarded as the gold standard for cholecystectomy. However, single-incision laparoscopic cholecystectomy (SLC) has been suggested to replace CLC. This study aimed at comparing long-term incidences of port-site hernia and chronic pain after SLC versus CLC. METHODS: We conducted a matched cohort study based on prospective data (Jan 1, 2009-June 1, 2011) from the Danish Cholecystectomy Database with perioperative information and clinical follow-up. Consecutive patients undergoing elective SLC during the study period were included and matched 1:2 with patients subjected to CLC using pre-defined criteria. Follow-up data were obtained from the Danish National Patient Registry, mailed patient questionnaires, and clinical examination. A port-site hernia was defined as a repair for a port-site hernia or clinical hernia located at one or more port sites. RESULTS: In total, 699 patients were eligible and 147 patients were excluded from the analysis due to pre-defined criteria. The rate of returned questionnaires was 83%. Thus, 552 (SLC, n = 185; CLC, n = 367) patients were analyzed. The median observation time was 48 months (range 1-65) after SLC and 48 months (1-64) after CLC (P = 0.940). The total cumulated port-site hernia rate was 4 % and 6 % for SLC and CLC, respectively (P = 0.560). Incidences of moderate/severe chronic pain were 4 % and 5 % after SLC and CLC, respectively (P = 0.661). CONCLUSIONS: We found no difference in long-term incidence of port-site hernia or chronic pain after SLC versus CLC.

BACKGROUND: Robotic-assisted surgery is steadily becoming more prominent. The majority of reports regarding port site hernias (PSHs) have involved laparoscopic procedures. Currently, it is common to suture the fascia at port sites that are 10 mm or larger; however, the closure of 5-mm port sites is not considered mandatory. The da Vinci® surgical system (Intuitive Surgical Inc., Sunnyvale, CA, USA) utilizes a distinctive 8-mm port. We report a case of an early-onset PSH at an 8-mm port site after robotic-assisted ileocecal resection. CASE PRESENTATION: A 74-year-old male patient with a body mass index of 19.7 kg/m2 was diagnosed with cecal cancer and underwent robotic-assisted ileocecal resection. A 3-cm midline incision was made at the umbilicus for insufflation. Under laparoscopic visualization, three ports (12 mm, 8 mm, and 8 mm) were inserted in the lower abdomen. An 8-mm port was inserted in the left subcostal region, and a 5-mm port was inserted in the left lateral abdomen. The procedure was performed without significant intraoperative complications. The fascia was closed only at the umbilicus and 12-mm port site; the fascia at the 8-mm port sites was not closed. The patient was initially discharged without complications; however, on postoperative day 11, the patient was urgently hospitalized again because of PSH incarceration. After manual reduction, the fascia was sutured closed under local anesthesia. The hernial defect was small and barely allowed the insertion of a little finger. There was no evidence of compression or significant damage to the fascia. On postoperative day 27, the patient was discharged after experiencing good recovery. CONCLUSIONS: Robotic-assisted colectomy could contribute to the risk of PSHs because of its surgical characteristics. Although routine closure of the fascia at 8-mm port sites is not mandatory, it may be beneficial in certain cases.
RESUMO
PURPOSE: Trocar site incisional hernia (TSIH) is a common complication of laparoscopic surgery. In the scientific literature there are few descriptions of methods or tools for its prevention. The aim of this report was to assess the effectiveness and safety of a prophylactic measure designed to lower rates of TSIH. METHODS: A multicenter randomized double-blinded clinical trial was performed in high-risk patients (diabetes mellitus and/or age ≥ 70 years and/or BMI ≥ 30 kg/m2 and/or extended incision for specimen retrieval) who underwent either elective or emergency laparoscopic cholecystectomy. Patients were assigned to prophylactic onlay polypropylene mesh fixation (intervention) or to standard trocar closure (control). The main aim was to analyze the efficacy of the intervention, taking occurrence of TSIH as the primary outcome. Clinical and radiological follow up lasted at least one year after surgery. Secondary endpoints were technique-related complications (surgical site occurrences). RESULTS: One hundred and forty-three patients were randomized and finally 116 were analyzed (64 in the intervention arm and 52 in the control arm). Groups were homogeneous. Mean [SD] age, 65 [18] years; 86 (60.6%) were women. The cumulative TSIH incidence was lower in the intervention group although the differences did not reach statistical significance, assessed either radiologically (16 [25.4%] vs 17 [31.5%], p = 0.538) or clinically (9 [16.1%] vs 9 [20], p = 0.613). No differences in surgical site infection, hematoma or seroma were detected. Mean follow-up was 670 days (range 223-1294). CONCLUSION: Our results show that, when properly assessed, the overall TSIH incidence is extremely high. Although polypropylene onlay mesh placement is safe, it does not appear to be effective in reducing the TSIH incidence rate. Radiological evaluation may be more accurate. TRIAL REGISTRATION: ClinicalTrials.org NCT03495557. Date of registration: April 12, 2018.
RESUMO
Laparoscopic surgery has become a widely accepted standard of care for numerous procedures in the modern world. Nearly every major surgical procedure previously only possible by employing open techniques may now be completed laparoscopically, attributable to the quick advancement of technology and surgeons' abilities. There are several complications associated with the laparoscopic port site, either infective, non-infective, or neoplastic. This study aims to explore the morbidity associated with the port site following laparoscopic surgery and discuss the risk factors for complications. The umbilical port was most frequently associated with port-site hernia (PSH), followed by the epigastrium and the left and right hypochondrium. Prolonged port manipulation and reinsertion, longer surgical times, failure to effectively close the fascial defect, and wound infection are responsible for the development of PSH. Port-site infection (PSI) is one avoidable adverse effect of laparoscopic surgery. Patients who have a history of diabetes, malnourishment, prolonged preoperative hospital stays, preoperative Staphylococcus aureus colonization of the nares, perioperative blood transfusions, and tobacco or steroid use are more likely to have PSI. Port-site hydatid cyst (PSHC) and port-site tuberculosis (PST) are rare but possible. While uncommon, a doctor should rule out endometriosis if a painful mass in the surgical scar, such as the trocar site, is discovered in a reproductive-age woman who has had pelvic or obstetric surgery in the past. Port-site metastasis (PSM) is the term for tumor-cell implantation at the trocar insertion site after a malignant tumor is removed laparoscopically. PSM has been reported in 1-2% of laparoscopic gynecologic surgical procedures. A few potential mechanisms for cell implantation at the port site include embolization of exfoliated cells during tumor dissection or hematogenous spread, air turbulence during long laparoscopic operations, and direct implantation onto the wound during forced, unprotected organ/tissue retrieval or from contaminated surgical instruments during tumor dissection. Nonetheless, the triggering mechanism is likely essentially multifaceted. Prevention is better than cure. Port-site hernia can be prevented using smaller trocars and meticulous rectus sheath defect closure at the end of surgery. The rest of the port site complications can be prevented by employing autoclavable laparoscopic hand instruments, utilizing autoclaved water to clean the instruments following disassembly, adhering to the recommended concentration, contact duration, and usage cycles when sterilizing instruments with liquid sterilizers, preventing bile or gut content from spilling into the operating room or the port site, using non-porous specimen retrieval bags for recovering the specimen, and thoroughly cleaning and irrigating the port site before closing the wound.
RESUMO
A 5 mm port site hernia during laparoscopic surgery is rarer than a 12 mm port site hernia. Here, we report the case of a 5 mm port site hernia in an 85-year-old woman who underwent long-term steroid therapy and laparoscopic right nephrectomy. There was also a hernia at the port site where the drain was placed. Due to the 5 mm port at the drain removal site, fascial suturing was impossible after removal of the drain, and countermeasures were difficult. However, we believe that patients at a higher risk of port need suturing wound patients like this and should be carefully observed.
RESUMO
In recent years, the Rutherford Morison incision has become synonymous with renal transplant surgery. However, this incision was originally intended for access to the sigmoid colon and pelvis, particularly in the case of a midline previously scarred from operation. We present a case of a middle-aged female with a caecal tumour, requiring resection. Upon examination, this patient was found to have large concomitant diastasis of the recti. A right-sided Rutherford Morison incision was utilized in performing a right hemicolectomy. Although the advantages of a minimally invasive approach to colonic resections are well described, laparoscopy was not utilized in the case discussed. Due to the wide area of anterior abdominal wall laxity, herniation is likely to develop at both port placement and specimen delivery sites. A similar outcome would result from a midline incision. However, a paramedian is an acceptable alternative to a Rutherford Morison incision in a case like this, as it is known to have very low rates of post-operative incisional herniation. While in modern times, its use may have become repurposed, the Rutherford Morison incision is one which should be remembered and used in the surgeons' armamentarium to improve clinical outcomes when necessary.
RESUMO
OBJECTIVE: Trocar site herniation is a recognized complication of minimally invasive surgery, but published data on trocar site herniation after robotic surgery are scarce. We sought to determine the incidence of trocar site herniation in women undergoing robotic surgery for gynecologic disease. METHODS: A retrospective review of robotic surgeries performed from January 1, 2006, through December 31, 2012, was conducted. Postoperative trocar site herniations were identified, along with time to presentation, location of herniation, and management. Patients were excluded if surgery was converted to laparotomy or traditional laparoscopy. The Wilcoxon rank-sum test was used to compare patients with and without herniation with respect to continuous variables, and Fisher's exact test was used to compare these 2 groups with respect to categorical variables. RESULTS: The study included 500 patients, 3 of whom experienced herniation at a single trocar site. The patients with and without herniation did not differ with respect to age, body mass index, smoking status, medical comorbidities, operating time, or estimated blood loss. All 3 herniations occurred at 12-mm trocar sites. Two herniations occurred at assistant port sites, and 1 occurred at the umbilical camera port site. The median time to herniation was 21 days (range, 8-38 days). One patient required immediate surgical intervention; the other 2 patients had conservative management. CONCLUSIONS: Trocar site herniation is a rare complication following robotic surgery. The most important risk factor for trocar site herniation appears to be larger trocar size, as all herniations occurred at 12-mm port sites.

CONTEXT: The rate of port site complications following conventional laparoscopic surgery is about 21 per 100,000 cases. It has shown a proportional rise with increase in the size of the port site incision and trocar. Although rare, complications that occur at the port site include infection, bleeding, and port site hernia. AIMS: To determine the morbidity associated with ports at the site of their insertion in laparoscopic surgery and to identify risk factors for complications. SETTINGS AND DESIGN: Prospective descriptive study. MATERIALS AND METHODS: In the present descriptive study, a total of 570 patients who underwent laparoscopic surgeries for various ailments between August 2009 and July 2011 at our institute were observed for port site complications prospectively and the complications were reviewed. STATISTICAL ANALYSIS USED: Descriptive statistical analysis was carried out in the present study. The statistical software, namely, SPSS 15.0 was used for the analysis of the data. RESULTS: Of the 570 patients undergoing laparoscopic surgery, 17 (3%) had developed complications specifically related to the port site during a minimum follow-up of three months; port site infection (PSI) was the most frequent (n = 10, 1.8%), followed by port site bleeding (n = 4, 0.7%), omentum-related complications (n = 2; 0.35%), and port site metastasis (n = 1, 0.175%). CONCLUSIONS: Laparoscopic surgeries are associated with minimal port site complications. Complications are related to the increased number of ports. Umbilical port involvement is the commonest. Most complications are manageable with minimal morbidity, and can be further minimized with meticulous surgical technique during entry and exit.
RESUMO
Key Clinical Message: Recently, the number of minimally invasive surgeries (MIS) is increasing; however, a specific postoperative complication of MIS such as port-site hernia needs to be recognized. A persistent postoperative ileus after MIS is rare and such symptoms need to be recognized as a probable sign of a port-site hernia. Abstract: Recently, minimally invasive surgery (MIS) approaches for early endometrial cancer have shown non-inferior oncologic outcomes with better perioperative morbidity than open approaches. Nevertheless, port-site hernias are a rare but specific surgical complication of MIS. Knowing the clinical presentation, surgery for port-site hernias could help clinicians manage this condition.
RESUMO
Most cases of port-site hernia were due to inadequate fascial closure of the port site. We experienced a rare case of hernia incarceration under the closed port-site fascia despite adequate closure of the fascia after robot-assisted laparoscopic radical cystectomy. In this case, the small intestine was incarcerated between the transversus abdominis and oblique abdominal muscles from the 12-mm trocar site for the assistant. We inserted forceps to release the incarceration, and the fascia and peritoneum of the port site were closed using a trocar site closure device under laparoscopy. We considered that all-layer suturing, including peritoneum and inner and outer oblique fascia suturing, was necessary for port-site closure, especially in patients with obesity, because hernias can occur with fascial closure alone.
RESUMO
INTRODUCTION: Port site herniation is a frequent complication of abdominal surgery, yet treatment strategies for multiple port site hernias are often difficult and case reports are rare. PRESENTATION OF CASE: A 72-year-old woman, with a history of multiple abdominal surgeries, underwent laparoscopic surgery for rectal prolapse four years prior. Three 12 mm ports were inserted into the umbilical region, right upper quadrant and right lower abdomen, subsequently, incisional hernias developed at all three sites. In addition, an incisional hernia developed in the lower abdomen, for a total of four incisional hernias. She was taking apixaban for atrial fibrillation, and since the standard surgical method of placing the mesh in the extraperitoneal space was judged to be high risk for postoperative bleeding and hematoma formation, we performed a laparoscopy-assisted intraperitoneal onlay mesh repair (IPOM). DISCUSSION: The key points of the surgery performed are: Laparoscopic surgery was initiated with a small incision in the umbilical region, using two 5 mm ports because we reasoned that using a 12 mm port could cause a new hernia. In the lateral hernia repair, a mesh was placed in the preperitoneal space on the dorsal side of the hernia, the mesh was sutured to the peritoneum because tucking cannot be performed if nerves are present on the dorsal aspect. The medial hernia was repaired by IPOM via a small laparotomy incision. CONCLUSION: For multiple incisional hernias, it is necessary to consider appropriate repair methods for each site.
