Indocyanine Green Fluorescent Lymphography During Open Inguinal Hernia Repair: Relationship Between Lymphatic Vessel Injury and Postoperative Hydrocele.

BACKGROUND: This prospective case series analyzed patients who underwent indocyanine green (ICG) fluorescent lymphography during open inguinal hernia repair. The aim of this study was to investigate the association between ICG leakage and postoperative hydroceles in patients who underwent inguinal hernia repair. MATERIALS AND METHODS: Data were analyzed from 40 patients who underwent primary open hernia repair between October 2020 and June 2021 (44 cases in total). Hydroceles were categorized into two types: symptomatic and "ultrasonic" (detected only by ultrasound imaging). RESULTS: In the univariate analysis, hernia type (p = 0.044) and ICG leakage (p = 0.007) were independent risk factors for postoperative ultrasonic hydroceles. Additionally, mesh type (p = 0.043) and ICG leakage (p = 0.025) were independent risk factors for postoperative symptomatic hydroceles. In the multivariate analysis, ICG leakage (p = 0.034) was an independent risk factor for postoperative ultrasonic hydroceles. CONCLUSIONS: ICG leakage after inguinal hernia repair was independently associated with postoperative ultrasonic and symptomatic hydroceles. These findings suggest a relationship between lymphatic vessel injury and the incidence of postoperative hydroceles.

Efficacy and Safety of Gastrointestinal Tumour Site Marking with da Vinci-Compatible Near-Infrared Fluorescent Clips: A Case Series.

BACKGROUND: The conventional near-infrared fluorescent clip (NIRFC) ZEOCLIP FS® has been used successfully in marking tumour sites during laparoscopic surgeries. However, this clip is difficult to observe with the Firefly imaging system equipped with the da Vinci® surgical system. We have been involved in the modification of ZEOCLIP FS® and development of da Vinci-compatible NIRFC. This is the first prospective single-centre case series study verifying the usefulness and safety of the da Vinci-compatible NIRFC. METHODS: Twenty-eight consecutive patients undergoing da Vinci®-assisted surgery for gastrointestinal cancer (16 gastric, 4 oesophageal, and 8 rectal cases) between May 2021 and May 2022 were enrolled. RESULTS: Tumour location was identified by the da Vinci-compatible NIRFCs in 21 of 28 (75%) patients, which involved 12 gastric (75%), 4 oesophageal (100%), and 5 rectal (62%) cancer cases. No adverse events were observed. CONCLUSION: Tumour site marking with da Vinci-compatible NIRFC was feasible in 28 patients enrolled in this study. Further studies are warranted to substantiate the safety and improve the recognition rate.

Prognostic significance of the cachexia index in patients with stage I-III colorectal cancer who underwent laparoscopic surgery.

PURPOSE: The prognostic significance of the cachexia index, a novel biomarker of cancer cachexia, remains unclear in colorectal cancer; we, therefore, evaluated this relationship. METHODS: This retrospective cohort study included 306 patients with stage I-III colorectal cancer who underwent R0 resection between April 2010 and March 2020. The cachexia index was calculated as (skeletal muscle index [cm2/m2] × serum albumin level [g/dL])/neutrophil-to-lymphocyte ratio. The overall and disease-free survival rates were analyzed using a Cox proportional hazards model. RESULTS: A low cachexia index was found in 94 patients. This group had significantly lower disease-free survival and overall survival than the high-cachexia index group (5-year survival, 86.3% vs. 63.1%, p < 0.01; 87.9% vs. 67.2%, p < 0.01). Multivariate analyses showed that T3 or T4 (hazard ratio [HR]: 2.56; 95% confidence interval CI 1.04-6.25, p = 0.039), stage III (HR: 3.77; 95% CI 1.79-7.93, p < 0.01), and a low cachexia index (HR: 2.27; 95% CI 1.31-3.90, p = 0.003) were significant independent predictors of the disease-free survival. CA19-9 ≥ 37.0 ng/mL (HR: 2.68; 95% CI: 1.37-5.24, p = 0.004), stage III (HR: 2.57; 95% CI 1.34-4.92, p = 0.004), and a low cachexia index (HR: 2.35; 95% CI 1.31-4.21, p = 0.004) were significant independent predictors of the overall survival. CONCLUSION: A low cachexia index might be a long-term prognostic factor of colorectal cancer.

Risk factors for refractory enterocutaneous fistula following button jejunostomy removal and its treatment using a novel extraperitoneal approach in patients with oesophageal cancer: a retrospective cohort study.

BACKGROUND: Enterocutaneous fistula after removal of the jejunostomy tube leads to multiple problems, such as cosmetic problems, decreased quality of life, electrolyte imbalances, infectious complications, and increased medical costs. However, the risk factors for refractory enterocutaneous fistula (REF) after button jejunostomy removal remain unclear. Therefore, in this study, we assessed the risk factors for REF after button jejunostomy removal in patients with oesophageal cancer and reported the surgical outcomes of the novel extraperitoneal approach (EPA) for REF closure. METHODS: This retrospective cohort study included 47 patients who underwent button jejunostomy removal after oesophagectomy for oesophageal cancer. We assessed the risk factors for REF in these patients and reported the surgical outcomes of the novel EPA for REF closure at the International University of Health and Welfare Hospital between March 2013 and October 2021. The primary endpoint was defined as the occurrence of REF after removal of the button jejunostomy, which was assessed using a maintained database. The risk factors and outcomes of the EPA for REF closure were retrospectively analysed. RESULTS: REFs occurred in 15 (31.9%) patients. In the univariate analysis, REF was significantly more common in patients with albumin level < 4.0 g/dL (p = 0.026), duration > 12 months for button jejunostomy removal (p = 0.003), and with a fistula < 15.0 mm (p = 0.002). The multivariate analysis revealed that a duration > 12 months for button jejunostomy removal (odds ratio [OR]: 7.15; 95% confidence interval [CI]: 1.38-36.8; p = 0.019) and fistula < 15.0 mm (OR: 8.08; 95% CI: 1.50-43.6; p = 0.002) were independent risk factors for REF. EPA for REF closure was performed in 15 patients. The technical success rate of EPA was 88.2%. Of the 15 EPA procedures, fistula closure was achieved in 12 (80.0%). The complications of EPA (11.7%) were major leakages (n = 3) and for two of them, EPA procedure was re-performed, and closure of the fistula was finally achieved. CONCLUSION: This study suggested that duration > 12 months for button jejunostomy removal and fistula < 15.0 mm are the independent risk factors for REF after button jejunostomy removal. EPA for REF closure is a novel, simple, and useful surgical option for patients with REF after oesophagectomy.

Vertical distance from navel as a risk factor for bowel obstruction associated with feeding jejunostomy after esophagectomy: a retrospective cohort study.

BACKGROUND: Placement of feeding jejunostomy (PFJ) during esophagectomy is an effective method to maintain adequate nutrition, but is associated with serious complications such as bowel obstruction and jejunal torsion. The purpose of the current study was to analyze the incidence, clinical features, and risk factors of bowel obstruction associated with feeding jejunostomy (BOFJ) after PFJ. METHODS: This was a retrospective cohort study of 70 patients who underwent esophagectomy with three-field lymph node dissection for esophageal cancer and treated with PFJ between March 2013 and December 2019 in our hospital. Abdominal dissection was performed under hand-assisted laparoscopic surgery (HALS) from March 2013 to March 2015, and was changed to complete laparoscopic surgery in April 2015. We compared patients with and without BOFJ, and the incidence of BOFJ was evaluated. The primary endpoint was incidence of BOFJ after PFJ. RESULTS: Six patients (8.5%) were diagnosed with BOFJ, all of whom were symptomatic and in the HALS group. In addition, 3 cases displayed histories of recurrent BOFJ (3, 3, and 5 times). Laparotomy was performed in all cases. Subgroup analysis of the HALS group showed a significant difference only in straight-line distance between the jejunostomy and navel as a significant pre- and perioperative factor (117 mm [101-130 mm] vs. 89 mm [51-150 mm], p < 0.001). Furthermore, dividing straight-line distance between the jejunostomy and navel into VD and HD, only VD differed significantly (107 mm [93-120 mm] vs. 79 mm [28-135 mm], p = 0.010), not HD (48 mm [40-59 mm] vs. 46 mm [22-60 mm], p = 0.199). CONCLUSIONS: VD between the jejunostomy and navel was associated with BOFJ after PFJ with HALS esophagectomy. PFJ < 9 cm above the navel during HALS esophagectomy might effectively prevent BOFJ.

Double Percutaneous Transesophageal Gastrotubing for Gastric Cancer: A Pilot Study.

BACKGROUND: The management of gastric cancer causing gastric outlet obstruction and dilatation must include decompression of the stomach and intravenous nutrition. Percutaneous transesophageal gastrotubing (PTEG) is an effective technique for either gastric decompression or enteral nutrition. Here, we investigated the efficacy and safety of double PTEG (dPTEG), that is, using PTEG for both purposes simultaneously, in patients with gastric cancer. MATERIALS AND METHODS: Eleven patients with gastric outlet obstruction due to gastric cancer were admitted to our hospital between January 2015 and March 2017 and enrolled in this study. Each patient underwent dPTEG as soon as possible. After dPTEG tubes were placed, gastric decompression was started immediately and enteral nutrition was started within 1 d. Feeding and decompression through the double tubes were continued until the day before operation. Using data from these patients, we investigated the efficacy and safety of dPTEG. RESULTS: dPTEG was performed successfully in all patients and no critical adverse effects were observed. Eight of the 11 patients underwent radical or palliative resection. Decompression of the stomach was achieved and nutritional status was significantly improved after dPTEG in all patients. CONCLUSIONS: We conclude that dPTEG is a safe and effective management technique for patients with gastric outlet obstruction and gastric dilatation due to gastric cancer.

Prophylactic retention suture for surgical site infection: a retrospective cohort study.

BACKGROUND: Surgical site infection (SSI) is a common complication of gastrointestinal surgery. Because retention suture is known to prevent abdominal wound dehiscence, it is only considered indicated in high-risk patients. At present, there are no clear indications for retention suture. The purpose of this study was to analyze the effect of prophylactic retention suture and to determine what situations indicate prophylactic retention suture against SSI. MATERIAL AND METHODS: Between January 2014 and January 2016, 135 patients who underwent midline laparotomy in our hospital were analyzed. Inclusion criteria for this study were patients with American Society Anesthesiologists' physical status classification system (ASA-PS score) ≥ 3 or emergent surgery. RESULTS: Of the 135 patients, 30 (22.2%) received prophylactic retention suture. Diabetes mellitus, surgical wound classification, large incision, and retention suture were associated with SSI in multivariate analysis. In subgroup analysis, SSI risk factors were analyzed in each surgical wound classification. Only in surgical wound classification class II and III did retention suture significantly reduce the risk of SSI (odds ratio = 0.100 [0.012-0.837], P = 0.034). In class IV, however, half the patients developed SSI, regardless of retention suture. Table 3 summarizes the results of the subgroup analysis. CONCLUSIONS: The present data suggest that prophylactic retention suture reduces SSI for surgical wound classification class II or III. For class IV operations, however, other methods to prevent SSI are necessary.

Crus incision without repair is a risk factor for esophageal hiatal hernia after laparoscopic total gastrectomy: a retrospective cohort study.

BACKGROUND: Although postoperative esophageal hiatal hernia (EHH) is primarily considered a post-operative complication of esophagectomy, it is also a rare post-operative complication of laparoscopic total gastrectomy (LTG), with a reported incidence rate of 0.5 %. The purpose of this study is to analyze the incidence, clinical features, and prevention of EHH following LTG for gastric cancer. METHODS: Between October 2008 and July 2014, 78 patients who underwent LTG for gastric cancer in our hospital were analyzed. We compared the crus incision group (in which the left crus of the diaphragm was incised without suture repair) with the crus conserving or repair group (in which the crus was preserved or the crus was incised and underwent suture repair). The primary endpoint was incidence of postoperative EHH. RESULTS: Of the 78 patients, 7 (9.0 %) developed postoperative EHH. Three of seven patients (42.9 %) were symptomatic and required an emergency operation for intestinal obstruction. Four of seven patients (57.1 %) were asymptomatic and did not require an operation. Incising the left crus of the diaphragm without suture repair during LTG was considered the only risk factor for postoperative EHH (0 of 29 for preserving the crus or incising and performing suture repair of the crus vs. 7 of 49 in crus incision without suture repair; p = 0.033). CONCLUSIONS: The present data suggest that incision of the crus without suture repair is associated with EHH after LTG. If crus incision is required, crus repair may be effective for the prevention of postoperative EHH.

Mesangial proliferative glomerulonephritis in murine malaria parasite, Plasmodium chabaudi AS, infected NC mice.

BACKGROUND: Malaria is an important tropical disease and has remained a serious health problem in many countries. One of the critical complications of malarial infection is renal injury, such as acute renal failure and chronic glomerulopathy. Few animal models of nephropathy related to malarial infection have been reported. Therefore, we developed and investigated a novel malarial nephropathy model in mice infected by murine malaria parasites. METHODS: NC mice and C57BL/6J mice were infected with Ttwo different murine malaria parasites, Plasmodium (P.) chabaudi AS and P. yoelii 17X. After the infection, renal pathology and blood and urinary biochemistry were analyzed. RESULTS: NC mice infected by the murine malaria parasite P. chabaudi AS, but not P. yoelii 17X, developed mesangial proliferative glomerulonephritis with endothelial damage, and decreased serum albumin concentration and increased proteinuria. These pathological changes were accompanied by deposition of immunoglobulin G and complement component 3, mainly in the mesangium until day 4 and in the mesangium and glomerular capillaries from day 8. On day 21, renal pathology developed to focal segmental sclerosis according to light microscopy. In C57BL/6J mice, renal injuries were not observed from either parasite infection. CONCLUSION: The clinical and pathological features of P. chabaudi AS infection in NC mice might be similar to quartan malarial nephropathy resulting from human malaria parasite P. malariae infection. The NC mouse model might therefore be useful in analyzing the underlying mechanisms and developing therapeutic approaches to malaria-related nephropathy.

The introduction of fluoroscopic surgery: A report of an initial trial case.

INTRODUCTION: Switching from white light to fluorescence mode is necessary to confirm the fluorescence during fluorescence-guided surgery. This case report presents the use of a syringe pump to continuously inject indocyanine green (ICG), which enabled the vessels to be visualised and the operation to be performed without switching. PRESENTATION OF CASE: An Asian male patient in his 40s underwent an interval appendectomy following conservative treatment for appendicitis. Laparoscopic surgery was performed using the VISIONSENSE® system. Diluted ICG (25 mg/15 mL) was intravenously administered at 1 mL/min. The appendiceal artery was visualised in light green, and the intensity of the visualisation was defined relative to the tissue surrounding the dissected appendiceal artery. The superior rectal artery and the vessels within the mesentery of the small intestine were confirmed to be continuously visualised throughout the surgery. Therefore, continuous ICG angiography made it possible to operate while keeping the appendiceal artery visible in this case. DISCUSSION: ICG angiography enabled the operation to be performed with the appendiceal artery continuously visualised. This method was developed for use in cancer surgery; however, since operations of longer duration are speculated to require larger doses of ICG, we opted to introduce this method in an initial trial for appendectomy. CONCLUSION: The fluoroscopic surgery using a syringe pump was feasible in this first case report without switching to white light mode.

Effect of low visceral fat area on long-term survival of stage I-III colorectal cancer.

OBJECTIVE: The prognostic significance of a low visceral fat area (VFA) in colorectal cancer (CRC) remains unclear. The aim of this study was to evaluate the prognostic effects of a low VFA on the long-term outcomes of patients with CRC after laparoscopic surgery. METHODS: This retrospective study included 306 patients with stages I-III CRC who underwent R0 resection. VFA was preoperatively measured via computed tomography using image processing software. Relapse-free survival (RFS) and overall survival (OS) rates were analyzed using the Cox proportional hazards model and Kaplan-Meier curves. RESULTS: Low VFA was identified in 153 patients. The low VFA group had significantly lower RFS and OS rates than did the high VFA group (5-y RFS rates: 72 versus 89%, P = 0.0002; 5-y OS rates: 72 versus 92%, P = 0.0001). The independent significant predictors of RFS were T3 or T4 disease (hazard ratio [HR], 2.75; 95% confidence interval [CI], 1.12-6.76; P = 0.027), stage III CRC (HR, 3.49; 95% CI, 1.82-6.69; P < 0.001), low psoas muscle index (PMI; HR, 2.12; 95% CI, 1.19-3.79; P = 0.011), and low VFA (HR, 2.12; 95% CI, 1.16-3.86; P = 0.014). The independent significant predictors of OS were age ≥65 y (HR, 2.59; 95% CI, 1.13-5.92, P = 0.024), carbohydrate antigen 19-9 levels ≥37 ng/mL (HR, 2.32; 95% CI, 1.18-4.58; P = 0.015), stage III CRC (HR, 2.66; 95% CI, 1.37-5.17; P = 0.004), low PMI (HR, 2.00; 95% CI, 1.06-3.77; P = 0.031), and low VFA (HR, 2.42; 95% CI, 1.24-4.70; P = 0.009). CONCLUSION: A low preoperative VFA was significantly associated with worse RFS and OS rates in patients who underwent CRC resection.

Preoperative Vertebral Fracture: A Prognostic Factor in Stage I-III Colorectal Cancer.

BACKGROUND/AIM: This study evaluated the prognostic impact of vertebral fractures (VFs) on the survival of patients with colorectal cancer (CRC). PATIENTS AND METHODS: We included 299 patients with stage I-III CRC who had undergone elective surgery. The patients were divided into the VF group (n=94) and non-VF group (n=205). VFs were assessed using sagittal computed tomography image reconstruction (Th11-L5) performed preoperatively. Disease-free survival (DFS) and overall survival (OS) rates were analyzed. RESULTS: The VF group had lower 5-year DFS and OS rates compared to the non-VF group (both, p<0.001). The independent predictors of DFS were carbohydrate antigen 19-9 (CA19-9) ≥37.0 ng/ml, T3/T4 disease, stage III CRC, osteopenia, and VF; for OS, CA19-9 ≥37.0 ng/ml, stage III, osteopenia, and VF. VF, compared with osteopenia, was a more significant prognostic factor for DFS and OS in patients with stage I+ II CRC (both, p<0.001). CONCLUSION: Preoperative VF was associated with worse DFS and OS following CRC resection.

Rare symptom of left inguinal abscess secondary to a retroperitoneal perforation of diverticulitis of the sigmoid colon: A case report.

RATIONALE: Complicated colorectal diverticulitis could be fatal, and an abscess caused by this complication is usually formed at the pericolic, mesenteric, or pelvic abscess. Therefore, we report a rare case of sigmoid colon diverticulitis that developed a large inguinal abscess. PATIENT CONCERNS: A woman in her 70s was admitted to our hospital with a chief complaint of left inguinal swelling and tenderness 1 week before admission. Physical examination showed swelling, induration, and tenderness in the left inguinal region. Blood tests revealed elevated inflammatory reaction with C-reactive protein of 11.85 mg/dL and white blood cells of 10,300/µL. Contrast-enhanced computed tomography showed multiple colorectal diverticula in the sigmoid colon, edematous wall thickening with surrounding fatty tissue opacity, and abscess formation with gas in the left inguinal region extending from the left retroperitoneum. DIAGNOSES: The diagnosis was sigmoid colon diverticulitis with large abscess formation in the left inguinal region. INTERVENTIONS: Immediate percutaneous drainage of the left inguinal region was performed, as no sign of panperitonitis was observed. Intravenous piperacillin-tazobactam of 4.5 g was administered every 6 hours for 14 days. OUTCOMES: The inflammatory response improved, with C-reactive protein of 1.11 mg/dL and white blood cell of 5600/µL. Computed tomography of the abdomen confirmed the disappearance of the abscess in the left inguinal region, and complete epithelialization of the wound was achieved 60 days after the drainage. The patient is under observation without recurrence of diverticulitis. LESSONS: We report a rare case of sigmoid colon diverticulitis that developed a large inguinal abscess, which was immediately improved by percutaneous drainage and appropriate antibiotics administration.

High Subcutaneous Fat Area Is an Independent Risk Factor for Parastomal Hernia after Transperitoneal Colostomy for Colorectal Cancer.

Objectives: Parastomal hernia (PSH) is a common complication of colostomy; however, its risk factors remain poorly investigated. In this study, we examined the associations between sarcopenia, visceral and subcutaneous fat, and PSH in patients who underwent transperitoneal colostomy for colorectal cancer. Methods: This retrospective, single-center, cohort study included 60 patients who underwent laparoscopic or robot-assisted abdominoperineal resection or Hartmann's procedure for colorectal cancer between November 2010 and February 2022. Stoma creation was uniformly performed using the transperitoneal approach, and PSH was diagnosed via abdominal computed tomography (CT) at 1 year postoperatively. Visceral fat areas (VFAs) and subcutaneous fat areas (SFAs) were measured through preoperative CT images using an image analysis system. Risk factors for PSH were retrospectively analyzed. Results: PSH was diagnosed in 13 (21.7%) patients. In the univariate analysis, PSH was significantly associated with body mass index >22.3 kg/m2 (p=0.002), operation time >319 min (p=0.027), estimated blood loss >230 mL (p=0.008), postoperative complications (p=0.028), stoma diameter >18.6 mm (p=0.015), VFA >89.2 cm2 (p=0.005), and SFA >173.2 cm2 (p=0.001). Multivariate analyses confirmed that SFA >173.2 cm2 (odds ratio: 16.7, 95% confidence interval 1.29-217.2, p=0.031) was an independent risk factor for PSH. Conclusions: Subcutaneous fat area is significantly associated with the development of PSH after transperitoneal colostomy. Applying these insights could help to prevent PSH.

Colonoscopy-assisted percutaneous sigmoidopexy (CAPS) for complete rectal prolapse treatment: Case series.

Background and study aims We have previously reported on the effectiveness of colonoscopy-assisted percutaneous sigmoidopexy (CAPS) for sigmoid volvulus treatment. This study describes the CAPS application to treat complete rectal prolapse by straightening and fixing the rectum. Complete rectal prolapse is common in older women. Due to their comorbidities, management must comprise a simple, safe, and reliable surgical method not involving general anesthesia or colon resection. Patients and methods We enrolled 13 patients in our outpatient department diagnosed with complete rectal prolapse between June 2016 and 2021. The endoscope was advanced into the anterior proximal rectal wall, straightening the intussuscepted sigmoid colon and rectum to approximate the puncture site. The fixation sites were anesthetized with 1% xylocaine, and a 2-mm skin incision was made using a scalpel. A two-shot anchor was used to fix the sigmoid colon to the abdominal wall (Olympus, Tokyo, Japan). Results The median patient age was 88 years (range: 50-94). The median CAPS procedure time was 30 minutes (range: 20-60). In one patient, the transverse colon was accidentally punctured and interposed between the abdominal wall and sigmoid colon, requiring a laparotomy to remove the causative fixation thread and provide re-fixation. Fecal incontinence was resolved in 10 of 13 cases. Conclusions CAPS is a quick and simple procedure. In addition, it is a treatment option for complete rectal prolapse that can be performed under local anesthesia.

Colonoscopy-assisted percutaneous sigmoidopexy for a complete rectal prolapse: A case report.

Colonoscopy-assisted percutaneous sigmoidopexy is a simple and swift procedure that does not require general anesthesia. While we first developed this procedure for treating sigmoid volvulus, we herein present the first case in which we used it to correct a complete rectal prolapse in an older patient. Existing treatment modalities for rectal prolapses are limited by high recurrence rates, greater invasiveness, and greater complications; thus, there is a need for minimally invasive techniques that are associated with lower recurrence rates and fewer complications. In this case, a woman in her 90s complained of persistent fecal incontinence, dysuria, anal pain, and difficulty in walking. She was diagnosed with a complete rectal prolapse of 15 cm and was treated with colonoscopy-assisted percutaneous sigmoidopexy. The sigmoid colon was tractioned colonoscopically and fixed to the abdominal wall to immobilize the prolapsed rectum. The patient developed no complications intraoperatively and postoperatively and experienced no recurrence during a 5-year postoperative period. This report documents the first case wherein colonoscopy-assisted percutaneous sigmoidopexy was used successfully to correct a complete rectal prolapse.

Utility of Novel Clavicle-lifting Technique in Mediastinal Thyroid Surgery: A Case Series Study.

BACKGROUND/AIM: Symptomatic mediastinal goitre requires surgery and is usually resectable using the cervical approach alone; however, sternotomy is occasionally required. Sternotomy is a highly invasive procedure, and its complications, including mediastinitis and osteomyelitis, can be critical. To date, there have been no reports of non-invasive techniques to avoid sternotomy for mediastinal thyroid tumours. We investigated the safety and efficacy of thyroidectomy using the clavicle lifting technique with a paediatric Kent hook. PATIENTS AND METHODS: This was a retrospective study of 8 patients who underwent thyroidectomy with a clavicle lifting technique between November 2014 and July 2021 at the Department of Surgery, International University of Health and Welfare Hospital. The primary endpoint was sternotomy avoidance rate and R0 resection rate. An extension retractor used in paediatric surgery was used for the clavicle lifting technique. RESULTS: Sternotomy avoidance rate and R0 resection rate were 100%. The mean operative time was 161±53.5 min, and the mean blood loss was 125.6±125.8 ml. There were no intraoperative or postoperative complications related to the clavicle lifting technique. CONCLUSION: Thyroidectomy with a clavicle lifting technique for mediastinal goitre and thyroid cancer is safe and useful because it avoids sternotomy without causing massive intraoperative bleeding or damage to other organs.
