ABSTRACT

BACKGROUND: The assessment of laparoscopic cholecystectomy (LC) skills using operating times has not been well reported. We examined the total and partial operating times for LC procedures performed by surgical trainees to determine the required number of surgeries until the surgical time stabilizes. METHODS: We reviewed the video records of 514 consecutive LCs using the three-port method, performed by 16 surgical trainees. The total and partial surgical times were calculated and correlated to the surgeons' experience. RESULTS: The median total surgical time for a trainee's first LC was 112 (range 71-226) minutes. It reduced rapidly after the first 20 LCs and plateaued to its minimum after approximately 60 cases. A statistically significant time decrease was observed between the first 10 (median, range 112, 46-252 min) and the next 50-59 cases (64, 34-198 min), but not between the 50-59 and the subsequent 100-109 cases (71, 33-127 min). The total times taken by trainees who had performed > 50 operations were not significantly different from those taken by instructors during the study period. Surgery for 125 patients with acute cholecystitis took a significantly longer time (median 99 vs. 74 min with non-acute cholecystitis); however, the abovementioned time reduction findings showed similar results regardless of the patient's acute inflammation status. The partial operating times around the cervical/cystic duct and gallbladder bed reduced uniformly between the first 10 and the following 50-59 cases. Although time variations in total and cervical/cystic duct operating times were not correlated to the surgical experience, time fluctuation of gallbladder bed procedures reduced after 60 cases. CONCLUSION: The time required to perform an LC was inversely correlated with the experience of surgical trainees and halved after the first 60 cases. The surgical experience required for LC time stabilization is approximately 60 cases.

ABSTRACT

A 55-year-old woman receiving treatment for anorexia nervosa presented with abdominal pain and right thigh pain. Her body mass index was 12.9 kg/m2 . Computed tomography showed fluid storage in the distal side of the right obturator foramen and revealed a dilated small bowel without a starting point of obstruction. We diagnosed a naturally reduced incarcerated right obturator hernia and performed elective surgery with a laparoscopic approach for hernia repair the next day. Intraperitoneal observation revealed bilateral obturator hernias and a left direct-type inguinal hernia. Transabdominal preperitoneal hernioplasty was performed using two self-gripping polyester meshes for bilateral obturator hernia repair and a lightweight 3D-shaped mesh for left inguinal hernia repair. Women with emaciation caused by anorexia nervosa may be more likely to have complex hernias, including obturator hernia, and laparoscopic approaches may be useful for preoperatively diagnosed nonstrangulated obturator hernias.

ABSTRACT

BACKGROUND: Surgical smoke during operation is a well-known health hazard for medical staff. This study aimed to investigate the dynamics of surgical smoke during open surgery or laparoscopic surgery for colorectal disease. METHODS: This study quantitated particulate matter (PM) counts as part of surgical smoke in 31 consecutive patients who underwent colectomy at the Niigata City General Hospital using a laser particle counter. Particles were graded by size as ≤ 2.5 µm PM (PM2.5) or > 2.5 µm PM (large PM). Operative procedures were categorized as either open surgery (n = 14) or laparoscopic surgery (n = 17). RESULTS: The median patient age was 72 (range 41-89) years and 58.1% were male. The total PM2.5, PM2.5 per hour, and maximum PM2.5 per minute counts during operation were significantly higher in open surgery than in laparoscopic surgery (P = 0.001, P < 0.001, and P = 0.029, respectively). Large PM counts (total, per hour, and maximum per minute) were also higher in the open surgery group than in the laparoscopic surgery group. The maximum PM2.5 concentration recorded was 38.6 µm/m3, which is considered "unhealthy for sensitive groups" according to the U.S. Environment Protection Agency air quality index standards, if it was a 24-h period mean value. CONCLUSION: Exposure to surgical smoke is lower during laparoscopic surgery than during open surgery for colorectal diseases.

ABSTRACT

PURPOSE: Previous studies have reported that sarcopenia increases the risk of postoperative complications following colorectal resection. This retrospective study assessed the postoperative complications of rectal resection associated with sarcopenia. METHODS: We retrospectively analyzed 262 patients who underwent curative low anterior resection for primary rectal cancer from January 2008 to May 2020 at our institution. The patients were divided into a sarcopenia group (normalized total psoas muscle area < 6.36 cm2/m2 in males and < 3.92 cm2/m2 in females; N = 49) and a non-sarcopenia group (N = 213). RESULTS: The overall rate of postoperative complications within 30 days of surgery was higher in the sarcopenia group than in the non-sarcopenia group (46.9 vs. 29.6%; P = 0.028). The rate of postoperative remote infections was higher in the sarcopenia group than in the non-sarcopenia group (12.2 vs. 2.8%; P = 0.012). Sarcopenia was found to be a predictor of remote infection by a multivariate analysis (odds ratio, 4.08; 95% confidence interval, 1.12-14.80; P = 0.033). CONCLUSION: Sarcopenia diagnosed using the psoas muscle index was found to be an independent predictive factor for postoperative remote infection after curative low anterior resection for rectal cancer.

ABSTRACT

A 60-year-old woman was admitted on account of presenting with bloody stools. She had a history of endometrial cancer surgery. Family history revealed 3 colorectal cancer cases among the first or second relatives. Colonoscopy and contrast- enhanced computed tomography revealed descending colon cancer and left renal pelvic cancer. We performed partial resection of the descending/transverse colon with D3 lymph node dissection and total resection of the left kidney and ureter with curative intent. Postoperative pathological diagnosis revealed descending colon cancer(pT4bN0M1c, pStage Ⅳc)and left renal pelvic cancer (T1N0M0, Stage Ⅰ). In this case, Lynch syndrome was suspected based on the family history and medical history. The clinical findings were consistent with Amsterdam Criteria Ⅱ. The microsatellite instability(MSI)test result was MSI-H and the BRAF genetic test result showed a wild type. Immunohistochemical staining of descending colon cancer tissue showed loss of expression of MSH2 and MSH6 proteins. Genetic counseling was provided because Lynch syndrome was strongly suspected. Capecitabine plus oxaliplatin therapy was performed for 6 months for descending colon cancer. Nine months postoperatively, the patient remained recurrence-free for both colon cancer and renal pelvic cancer. We report a case of suspected Lynch syndrome triggered by double cancer of the descending colon and renal pelvis.

ABSTRACT

INTRODUCTION: While Asian populations develop colonic diverticular disease predominantly in the right colon, Western populations mainly present with left-sided disease. The present study aimed to clarify the outcomes of surgical treatment for right-sided colonic diverticular bleeding. METHODS: Medical records of 43 patients who underwent surgery for right-sided colonic diverticular bleeding between 2010 and 2019 were reviewed. Those whose general condition became unstable underwent open surgery at our institution. Patients were then divided into two groups, the open surgery group (n = 17) and laparoscopic surgery group (n = 26), after which operative outcomes between both groups were compared. RESULTS: This study included 36 men and seven women with a median age of 76 (range: 37-91) years. Laparoscopic surgery had a significantly longer operative time (183.5 minutes vs 110 minutes; P < .001) and significantly lower intraoperative blood transfusion rate (19.2% vs 82.4%; P < .001) than open surgery. The laparoscopic surgery group had earlier resumption of postoperative meals than open surgery group (postoperative day 3 vs postoperative day 4; P = .010). No significant difference in postoperative complications was observed between both groups. With regard to long-term outcomes, none of the cases exhibited rebleeding from the right-sided colon. CONCLUSION: The present study revealed that laparoscopic surgery promoted lower intraoperative blood transfusion rates and earlier resumption of postoperative meals compared to open surgery for right-sided colonic diverticular bleeding. Hence, laparoscopic surgery can be feasible for right-sided colonic diverticular bleeding provided that the patient's general condition is stable.

ABSTRACT

OBJECTIVES: Incisional hernia is a common problem after colorectal surgery, and a laparoscopic approach does not reduce the incisional hernia rate. Previous reports have described the risk factors for incisional hernia; however, the impact of suture materials remains unclear. As such, this study compared the incisional hernia rate using different suture materials for abdominal wall closure after laparoscopic colorectal cancer surgery. METHODS: Patients undergoing laparoscopic colorectal cancer surgery between January 2014 and December 2016 were included in this study. We separated patients into the following two groups based on the suture materials used for abdominal wall closure: (1.) fast-absorbable group and (2.) non-absorbable group. The primary outcome was incisional hernia rate that was diagnosed using computed tomography. We compared outcomes between these two groups using propensity score matching. RESULTS: Before matching, 394 patients were included (168 in the fast-absorbable group and 226 in the non-absorbable group). After one-to-one matching, patients were stratified into the fast-absorbable group (n = 158) and the non-absorbable group (n = 158). The incisional hernia rate was higher in the fast-absorbable group than in the non-absorbable group (13.9% vs. 6.3%; P = 0.04). The median time to develop an incisional hernia was significantly shorter in the fast-absorbable group (6.7 months vs. 12.3 months; P < 0.01). The incidence of surgical site infection was not different between the two groups, but the incidence of suture sinus was lower in the fast-absorbable group (0% vs. 5.1%; P < 0.01). CONCLUSIONS: The use of fast-absorbable sutures may increase the risk of incisional hernia after laparoscopic colorectal cancer surgery.

ABSTRACT

PURPOSE: Outcomes following surgery for advanced gallbladder carcinoma remain unsatisfactory. This study aimed to determine the surgical outcome and effectiveness of adjuvant chemotherapy according to TNM stage in patients with gallbladder carcinoma. METHODS: A total of 200 patients undergoing surgery for gallbladder carcinoma were enrolled. Clinicopathological data were evaluated and surgical outcomes were compared between patients with and without adjuvant chemotherapy according to TNM stage. RESULTS: The 5-year overall survival (OS) after resection for patients with stage I (n = 27), IIA (n = 18), IIB (n = 28), IIIA (n = 25), IIIB (n = 43), IVA (n = 7), and IVB (n = 52) disease was 90.8%, 94.4%, 73.6%, 33.7%, 57.7%, 14.3%, and 11.8%, respectively (p < 0.001). R0 resection was performed in all patients with stage I or II disease, in 89.7% of those with stage III disease, and 69.5% of those with stage IV disease. For patients with stage III disease, adjuvant chemotherapy was associated with improved OS (5-year OS, 60.9% vs. 41.1%; p = 0.028) and was an independent prognostic factor (hazard ratio, 2.045; p = 0.039). For patients with stage IV disease, adjuvant chemotherapy appeared to affect OS (5-year OS, 25.1% vs. 5.3%; p = 0.041); R0 resection (hazard ratio, 1.882; p = 0.040) was the only independent prognostic factor. CONCLUSION: TNM stage clearly predicts survival after resection of gallbladder carcinoma. R0 resection with adjuvant chemotherapy is recommended for long-term survival in the multimodal management of patients with stage III or IV gallbladder carcinoma.

ABSTRACT

BACKGROUND: The role of surgery in the management of primary cystic duct carcinoma (CDC) remains unclear especially in advanced disease. This study aimed to evaluate long-term outcomes in patients undergoing surgery for primary CDC. METHODS: From a multi-institutional database, we identified 41 patients who underwent surgery for primary CDC, defined as a part of gallbladder carcinoma with the tumor centre located in the cystic duct. RESULTS: Of the 41 patients, 31 (75.6%) underwent preoperative biliary drainage for jaundice. Twenty-eight (68.3%) patients underwent extensive resection including major hepatectomy (n = 21), pancreaticoduodenectomy (n = 4), or both procedures (n = 3). Thirty-four (82.9%) patients had ≥ pT3 tumor, while 31 (75.6%) patients had involvement of contiguous organs/structures. Nodal and distant metastasis was found in 26 (63.4%) and 7 (17.1%) patients, respectively. Most patients (90.2%) had perineural invasion. Median overall survival was 23.7 months in all 41 patients. Factors independently associated with both overall and disease-specific survival were pN (P = 0.003 and P = 0.007, respectively) and pM (P = 0.003 and P = 0.013, respectively) classification. Median survival was 75.3, 17.7, and 5.2 months for patients with pN0M0 (n = 14), pN1/2pM0 or pN0pM1 (n = 21), and pN1/2pM1 (n = 6) disease, respectively (P < 0.001). CONCLUSIONS: Primary CDC is characterized by locally advanced disease with aggressive histopathological characteristics at surgery, leading to extensive resection during treatment. Surgery provides potential benefits for patients with pN0pM0 disease, whereas pN1/2 and/or pM1 status appear to have strong adverse effects on survival.

ABSTRACT

INTRODUCTION: Portosystemic collaterals (PsC) are a common finding in patients with cirrhosis who need liver transplantation (LT), and PsCs may cause several problems before and after LT. We report a case of successful surgical treatment of severe hepatic encephalopathy (HE) caused by PsC after living-donor LT (LDLT). CASE: A 71-year-old woman with hepatocellular carcinoma underwent LDLT for chronic hepatitis C virus infection at 64 years of age. The splenocaval collateral vein was ligated during LDLT to prevent portal flow steal. A recurrent episode of coma due to HE was triggered 7 years after LDLT and gradually became refractory to any drug treatments. Contrast-enhanced computed tomography revealed the development of the right gastroepiploic vein (RGEV), which flowed to the inferior vena cava via the inferior mesenteric vein (IMV). Owing to the chronic kidney disease (estimated glomerular filtration rate, 11-31 mL/min), interventional radiology (IVR) was not indicated, so surgical treatment was selected to treat the symptom. PsC was resected at the point of the RGEV and IMV, just before flowing into the IVC with vascular staplers. Antegrade portal blood flow was obtained by ultrasonography 2 days after surgery, and the patient was discharged from the hospital 26 days after the operation. After discharge, she has had no recurrent episode of HE. CONCLUSION: Surgical resection of the PsC was effective for treatment of HE caused by shunt flow after LDLT.

ABSTRACT

A 68-year-old male patient received a living donor kidney transplantation 8 years earlier for end-stage kidney disease secondary to IgA nephropathy. His post-transplantation follow-up had been routinely performed with laboratory examinations, ultrasound, and computed tomography (CT). His kidney graft function had been excellent and stable, as shown by a baseline serum creatinine level of 1.0 mg/dL. At referral, regular follow-up ultrasound and CT showed allograft hydroureteronephrosis. He did not have any complaints, but his physical examination revealed right inguinal bulging that was 3.5 × 3.5 cm. Abdominal enhanced CT revealed transplant allograft hydroureteronephrosis due to ipsilateral herniation of ureteroneocystostomy into the right inguinal canal. His serum creatinine level was slightly elevated (1.1 mg/dL). Then, he underwent an open right inguinal hernia repair. Paraperitoneal allograft hydroureteronephrosis and bladder herniation was confirmed at surgery, and hernioplasty with polypropylene mesh reinforcement was successfully performed. The postoperative course was uneventful. He was discharged on the seventh day after surgery. Six weeks after surgery, CT revealed disappearance of allograft hydroureteronephrosis and no sign of inguinal hernia recurrence with the serum creatinine stable at 1.0 mg/dL. Transplant ureteral obstruction due to inguinal hernia is a rare complication after kidney transplantation. However, transplant ureter or bladder herniation should be considered in the differential diagnosis of graft hydroureteronephrosis for preventing allograft loss.

ABSTRACT

BACKGROUND: This study aimed to investigate the incidence and distribution of regional lymph node metastasis according to tumor location, and to clarify whether tumor location could determine the extent of regional lymphadenectomy in patients with pathological T2 (pT2) gallbladder carcinoma. METHODS: In total, 81 patients with pT2 gallbladder carcinoma (25 with pT2a tumors and 56 with pT2b tumors) who underwent radical resection were enrolled. Tumor location was determined histologically in each gallbladder specimen. RESULTS: Survival after resection was significantly worse in patients with pT2b tumors than those with pT2a tumors (5-year survival, 72% vs. 96%; p = 0.027). Tumor location was an independent prognostic factor on multivariate analysis (hazard ratio, 14.162; p = 0.018). The incidence of regional lymph node metastasis was significantly higher in patients with pT2b tumors than in those with pT2a tumors (46% vs. 20%; p = 0.028). However, the number of positive nodes was similar between the two groups (median, 2 vs. 2; p = 0.910). For node-positive patients with pT2b tumors, metastasis was found in every regional node group (12%-63%), whereas even for node-positive patients with pT2a tumors, metastasis was observed in regional node groups outside the hepatoduodenal ligament. CONCLUSIONS: Tumor location in patients with pT2 gallbladder carcinoma can predict the presence or absence of regional lymph node metastasis but not the number and anatomical distribution of positive regional lymph nodes. The extent of regional lymphadenectomy should not be changed even in patients with pT2a tumors, provided that they are fit enough for surgery.

ABSTRACT

A 78-year-old woman with jaundice was referred to our hospital. On admission, serological testing for viral hepatitis was negative and serum levels of AFP and PIVKA-Ⅱ were elevated(925 ng/mL and 6,820 mAU/mL, respectively). Computed tomography revealed a main tumor measuring 3 cm in size at segment 1 of the liver and bile duct tumor thrombus extending to the right hepatic duct. A diagnosis of hepatocellular carcinoma with a bile duct tumor thrombus was made. After endoscopic biliary drainage for obstructive jaundice and transarterial chemoembolization for the lesions, she underwent left hepatectomy, resection of the caudate lobe, extrahepatic bile duct resection, and cholecystectomy. The hepatic side of the extrahepatic bile duct was transected at the confluence of the right anterior and posterior ducts because invasion of the tumor thrombus to the right hepatic duct was suspected on cholangioscopy. Histological examination revealed the tumor to be a moderately differentiated hepatocellular carcinoma with bile duct tumor thrombus. Surgical margins were negative, and vascular invasion was not found. She remains alive and well with no evidence of disease 64 months after hepatectomy.

ABSTRACT

An 82-year-old man with a diagnosis ofintraductal papillary mucinous carcinoma(IPMC)underwent pancreaticoduodenectomy followed by adjuvant chemotherapy with S-1. Six months after surgery, he had upper abdominal pain, and CT demonstrated a recurrent intraabdominal tumor located at the surgical incision scar. It was diagnosed as a solitary peritoneal recurrence, and palliative radiation therapy at a dose of 30 Gy was performed for the relief of abdominal pain after administration ofoxycodone. He was free ofpain without pharmacological therapy and received subsequent chemotherapy with nabpaclitaxel plus gemcitabine(GnP). He remains free ofpain and alive without progression ofthe disease 24 months after recurrence. Hypofractionated-accelerated radiotherapy is feasible and results in pain relief for local recurrence of IPMC.

ABSTRACT

A 77-year-old woman presented with peritoneal metastases from a pancreatic neuroendocrine tumor(p-NET). At the age of 56 years, she underwent distal pancreatectomy for p-NET, which was pathologically diagnosed as G2. She underwent right hemihepatectomy for liver metastasis(S6)from the p-NET 10 years post-pancreatectomy. Eight years post-hepatectomy, radiofrequency ablation(RFA)was attempted for liver metastasis(S4)from the p-NET. However, RFA was not completed because of hematoma development along the needle tract of RFA. She underwent partial hepatectomy for this lesion 6 months post-RFA. Two years post-RFA, localized peritoneal metastases on the right diaphragm were detected. She underwent en bloc tumor resection with partial resection of the diaphragm. She remains alive and well with no evidence of disease 2 years post-resection of the peritoneal metastases from the p-NET.

ABSTRACT

Recent advances in dimensional imaging, surgical technique, and perioperative patient care have resulted in increased rates of complete resection with histopathologically negative margins and improved surgical outcomes in patients with extrahepatic cholangiocarcinoma. However, achieving cancer-free resection margins at ductal stumps in surgery for this disease remains challenging because of longitudinal extension, which is one of the hallmarks of extrahepatic cholangiocarcinoma. When the ductal resection margins are shown to be positive on examination of frozen sections, discrimination between carcinoma in situ and invasive carcinoma is clinically important because residual carcinoma in situ may lead to late local recurrence whereas residual invasive carcinoma is associated with early local recurrence. Residual invasive carcinoma at the ductal margins should be avoided whenever technically feasible. Residual "carcinoma in situ" at the ductal margins appears to be allowed in resection for the advanced disease because it has less effect on survival than other adverse prognostic factors (pN1 and/ or pM1). However, in surgery for early-stage (pTis-2N0M0) extrahepatic cholangiocarcinoma, residual carcinoma in situ at the ductal margins may have an adverse effect on long-term survival, so should be avoided whenever possible. In this review, we focus on the histopathological term "carcinoma in situ," the biological behavior of residual carcinoma in situ at ductal resection margins, intraoperative histological examination of the ductal resection margins, outcome of additional resection for positive ductal margins, and adjuvant therapy for patients with positive margins.

ABSTRACT

A 56-year-old woman was referred to our hospital with complaints of appetite loss and abdominal distension. Enhanced abdominal computed tomography revealed a giant retroperitoneal tumor. We performed en bloc tumor resection. The histological diagnosis was of a dedifferentiated liposarcoma. One year after the initial surgery, 2 tumors were detected around the pancreas using computed tomography. We made a diagnosis of recurrent retroperitoneal liposarcoma and attempted surgical removal of the tumors. However, 1 of the tumors firmly adhered to the pancreas and duodenum; thus, we performed subtotal stomach-preserving pancreaticoduodenectomy to remove the tumors. The histological diagnosis was the same as that obtained during the initial surgery: a dedifferentiated liposarcoma. The patient remains alive and well with no evidence of disease 2 years after the initial surgery.

ABSTRACT

Peritoneal metastasis is relatively rare in patients with hepatocellular carcinoma(HCC). No consensus has been reached regarding the treatment of this type of metastasis. Herein, we report 3 patients who underwent resection of peritoneal metastasis due to HCC. Case 1: A 48-year-old man underwent hepatectomy twice and radiofrequency ablation(RFA)once for HCC. Eight years after the initial resection, he underwent resection of peritoneal metastasis in the pelvic floor. He is alive with disease 17 months after the last operation. Case 2: A 71-year-old man with a history of percutaneous ablation therapy for HCC 3 times underwent hepatectomy for recurrent HCC. During the laparotomy, a peritoneal metastatic tumor was found near the live tumor, and simultaneous resection of both the tumors was performed. The patient died of recurrent disease 20 months after the last resection. Case 3: A 58-year-old man underwent hepatectomy for HCC and RFA for its recurrence. Peritoneal metastasis that invaded the duodenum was detected 8 years after the hepatectomy. Although the metastatic tumor was resected, he died of the carcinoma 2 months after the resection. We concluded that resection of peritoneal metastasis provides a survival benefit for selected patients with HCC.

ABSTRACT

A 59-year-old woman with pancreatic cancer underwent pancreaticoduodenectomy. The tumor was histologically diagnosed as a well-differentiated tubular adenocarcinoma with a small amount of mucinous component. After resection, the patient underwent hepatic perfusion therapy using 5-FU and gemcitabine chemotherapy for 1 year. 7 years after the initial surgery, CT and PET-CT revealed an isolated enlarged lymph node in the left neck. As the patient had no other metastasis, lymphadenectomy was performed. A diagnosis of lymph node metastasis originating from pancreatic cancer was confirmed on the basis of histological and immunohistopathological assessments. After the second resection, chemotherapy with S-1 was administered for 1 year. The patient has been alive without tumor relapse for 11 years. In patients with late recurrence after pancreatectomy, aggressive isolated lymph node resection and maintained chemotherapy may contribute to the improvement in prognosis.
