RESUMO
This clinical image presents an unusual report of simultaneous laparoscopic resection of a hydrocele of the canal of Nuck and an ovarian tumor. Laparoscopic treatment with a proper approach is a useful technique in some cases.
RESUMO
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.

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 â £c)and left renal pelvic cancer (T1N0M0, Stage â ). In this case, Lynch syndrome was suspected based on the family history and medical history. The clinical findings were consistent with Amsterdam Criteria â ¡. 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.

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.

PURPOSE: We evaluated the oncological outcomes of bridge to surgery (BTS) using stent compared with surgery alone for obstructive colorectal cancer. METHODS: Consecutive patients who underwent curative resection for stages II to III obstructive colorectal cancer at our institution from January 2009 to March 2020, were registered retrospectively and divided into 43 patients in the BTS group and 65 patients in the surgery alone group. We compared the surgical and oncological outcomes between the 2 groups. RESULTS: Stent-related perforation did not occur. One patient in whom the stent placement was unsuccessful underwent emergency surgery with poor decompression (clinical success rate, 97.7%). The pathological characteristics were not significantly different between the groups. The following surgical outcomes in the BTS group were superior to those in the surgery alone group; nonemergency surgery (P<0.001), surgical approach (P=0.006), and length of hospital stay (P=0.020). The median follow-up time was 44.9 months (range, 1.1-126.5 months). The 3-year relapse-free survival rates were 68.4% and 58.2% (P=0.411), and the overall survival rates were 78.3% and 88.2% (P=0.255) in the surgery alone and BTS groups, respectively. The 3-year locoregional recurrence rates were 10.2% and 8.0% (P=0.948), and distant metastatic recurrence rates were 13.3% and 30.4% (P=0.035) in the surgery alone and BTS groups, respectively. CONCLUSION: This study revealed that BTS with stent may be associated with a higher frequency of distant metastatic recurrence. Stent for stages II to III obstructive colorectal cancer potentially worsens oncological outcomes.
RESUMO
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.

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.

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.
RESUMO
A 63-year-old man who underwent robot-assisted laparoscopic low anterior resection and right lateral lymph node dissection (LLND) for rectal cancer presented with right thigh pain, nausea, vomiting, and abdominal pain on postoperative day 17. CT revealed dilated small bowel in the pelvis, and a small bowel loop was detected outside the internal iliac artery branch. Emergent laparoscopic surgery revealed the migration of the small bowel into the space beneath the right obturator nerve. The herniated bowel was reduced, and the obturator nerve was sharply dissected from the herniated bowel and preserved. The hernial orifice was left unrepaired. Postoperative recovery was uneventful, and the right thigh pain disappeared. It is important to consider the possibility of internal herniation beneath the obturator nerve after minimally invasive lateral lymph node dissection for rectal cancer.

PURPOSE: We report a case in which pigmented peritoneal deposits were found during laparoscopic surgery following preoperative endoscopic tattooing for sigmoid colon cancer. METHODS: The patient's clinical, endoscopic, and histological data from the Niigata City General Hospital were reviewed, as well as the literature on laparoscopic surgery involving the preoperative endoscopic tattoo, with a focus on the relevance of peritoneal deposits and tattooing ink. RESULTS: A 71-year-old man presented to our hospital complaining of vomiting and abdominal distention. Abdominal computed tomography revealed obstructive sigmoid colon cancer. An emergency endoscopic colon stenting procedure and injection of 0.2 ml India ink to the submucosal layer of the tumor's anal side were performed. Laparoscopic-assisted sigmoid colectomy was done 14 days after stenting. At surgery, seven small peritoneal deposits were seen in the rectovesical pouch and at the site adjacent to the tumor. All peritoneal deposits were stained by the ink. Gross leakage of the ink into extraintestinal sites was seen. The seven peritoneal deposits were resected under laparoscope. Histological findings revealed that the seven peritoneal deposits were composed of adenocarcinoma and carbon pigments. Immunohistochemical staining for cluster of differentiation 163 showed that the carbon pigments in the peritoneal deposits were within macrophages. CONCLUSIONS: The possibility of the tattooing procedure causing peritoneal dissemination cannot be completely denied, but it can be hypothesized that the carbon pigmentation was transferred to peritoneal deposits by macrophages. In the future, we hope that this phenomenon becomes a keystone for diagnoses and treatments for peritoneal dissemination.

INTRODUCTION: The purpose of this study was to evaluate the safety and efficacy of a novel continuous incision technique for the cystic duct and the bile duct over the orifice for laparoscopic transcystic choledocholithotomy (LTCL). METHODS: LTCL was attempted in 103 consecutive patients from January 1998 to March 2015 and was successful in 96 patients. The cystic duct confluence was made by cutting upward from the orifice in 19 patients. The cystic duct was incised downward beyond the orifice to the bile duct in the other 77 patients. Both of these procedures involved LTCL. RESULTS: LTCL was successful in 96 patients. It failed in seven patients because of large bile duct stones (BDS), left lateral entry of the cystic duct, or the cystic duct's small diameter. The success rates of LTCL were 98% (47/48), 96% (42/44), and 64% (7/11) for patients with BDS <10 mm, 10-20 mm, and ≥20 mm, respectively. The success rate for removing BDS <20 mm was significantly higher than the removal rate for BDS ≥20 mm (P < 0.0001). There was no significant difference between the incidences of complications associated with BDS ≥10 mm and with BDS <10 mm (P = 0.49). In those who underwent successful LTCL, complications occurred in 3 of 23 patients with failed preoperative duodenoscopic sphincterotomy and in 9 of the other 73 patients; the incidence of complications did not significantly differ between these groups (P = 0.93). CONCLUSION: LTCL is safe and feasible for exploration of the bile duct and removal of BDS <20 mm.

A 40-year-old woman visited her primary care physician because she had pain in the upper right part of the abdomen. She was diagnosed with descending colon cancer with multiple liver metastases, and was referred to our department. After a laparoscopic abdominal colectomy for removal of the original lesion, chemotherapy was initiated with a modified combination of folinic acid, 5-fluorouracil, and oxaliplatin (mFOLFOX6) + panitumumab. After 12 courses of treatment with the mFOL FOX6 + panitumumab combination, followed by 13 courses of the simplified biweekly 5-fluorouracil and Leucovorin (sLV5FU2) + panitumumab combination, her liver tumors had regressed to about 90% of their original size. A laparoscopic partial hepatectomy was successfully performed. Histopathological examination indicated a Grade 2 regression of the tumor in response to chemotherapy. This report highlights the effectiveness of "conversion therapy" after chemotherapy with the mFOLFOX6+panitumumab combination, especially in those patients with multiple liver metastases from colorectal cancer.

We aimed to evaluate the reproducibility of cetuximab combination chemotherapy as a standard treatment for patients with metastatic colorectal cancer in our hospital using actual clinical data. This study included 14, 9, and 4 patients who received third-line, second-line, and first-line treatment, respectively. The overall response rate(RR), progression-free survival( PFS), and overall survival(OS)were calculated according to treatment line and were compared with the results of largescale clinical studies. In patients undergoing third-line treatment, the RR was 14.3%, while the median PFS and OS were 2.9 and 9.6 months, respectively. These results were almost identical to those of the NCIC CTG CO. 17 study. In patients undergoing second-line treatment, the RR was 22.2% and the median PFS and OS were 5.8 and 7.1 months, respectively. These results were not inferior to those of the BOND study. In patients undergoing first-line treatment, partial response was observed in 75% of patients and stable disease was observed in 25% of patients. One patient subsequently underwent surgery. The RR(75%)was equal to that observed in the CRYSTAL study and the OPUS study. Standard treatment using cetuximab combination chemotherapy was found to be reproducible as third-line and second-line treatments in our clinical practice. Few patients received first-line treatment; hence, a larger number of patients will have to be evaluated in the future. Nevertheless, the administration of cetuximab combination chemotherapy may be appropriate as a medical treatment strategy for patients with metastatic colorectal cancer.

BACKGROUND: Many cases of choledocholiths formed around sutures and clips used during cholecystectomy have been reported. We describe a case of gallstone formation around a nylon suture after non-biliary surgery. To the best of our knowledge, this is the first report of such a case. CASE PRESENTATION: A 75-year-old Japanese man, who had undergone distal gastrectomy for gastric cancer and reconstruction with the Billroth II method 8 years earlier, presented with gastric discomfort. Abdominal ultrasonography was conducted and we diagnosed cholecysto-choledocholithiasis with dilatation of the intrahepatic bile duct. He underwent cholecystectomy and cholangioduodenostomy for choledocholith removal. Gallstones, which had formed around a nylon suture used during the previous gastrectomy, were found in the bile duct. Sutures of the same material had also been placed on the duodenum. Chemical analysis revealed that the stones were composed of calcium bilirubinate. The patient was discharged on postoperative day 19, and choledocholithiasis has not recurred thus far. CONCLUSION: The findings from this case suggest that standard, non-resorbable sutures used in gastrectomy may be associated with the formation of bile duct stones; therefore, absorbable suture material may be required to avert gallstone formation even in the case of gastrectomy.

We report an extremely rare case of adult intussusception caused by anisakiasis. A 41-year-old man was admitted into our hospital for right lower abdominal colicky pain. Ultrasonography and computed tomography revealed the presence of intussusception. As pneumo-dynamic resolution by colonoscopy failed, surgery was performed. The anisakis body was found in the submucosal layer of the resection specimen. The patient was discharged 9 d after the operation. Anisakiasis may cause intussusception in any country where sushi or sashimi now exists as a popular food. If suspicious, detailed clinical interview as to food intake prior to symptom development is crucial.

The patient was a 68-year-old male who had advanced rectal cancer with aortic bifurcation lymph node metastasis, who was given neo-adjuvant chemotherapy by IRIS, a combination of S-1 80 mg/m(2)/day (2-week administration and 1-week rest) and CPT-11 100 mg/day (day 1, 15). After 2 courses of this neo-adjuvant chemotherapy, a complete response (CR) was noted by CT scan and endoscopy. We were able to conduct a super low anterior resection of the colon and rectum. Postoperative histopathological examination of the resected rectum and lymph nodes showed only the spot of residual cancer tissue and the degeneration of cancer cells and fibrosis, revealing that the operation had been conducted radically. The changes from neo-adjuvant chemotherapy were judged to be Grade 2. And we could thus conduct the radical operation. The treatment was completed without adverse events. IRIS therapy can be an effective method as neo-adjuvant chemotherapy.

The patient was a 73-year-old male. Under a diagnosis of advanced cecal colon cancer with metastasis to Virchow's and paraaortic lymph nodes and lungs, a laparoscopic-assisted ileocecal resection with D2 lymph node dissection was performed. Histological examination of the resected specimens revealed moderately-differentiated adenocarcinoma which had invaded the terminal ileum. The lesion was judged to be SI(ileum), N2, H0, P0, M1(Virchow's lymph node, No. 216, lungs), Stage IV. After the operation, he received chemotherapy with 5-FU/l-LV(RPMI method), LV/UFT, FOLFOX, FOLFIRI in succession, and cancer aggravation was generally controlled. He has survived for 3 years since operation, and shows good QOL under the treatment.

BACKGROUND/AIMS: Pouchitis is the most frequent complication of ileal pouch-anal anastomosis for patients with ulcerative colitis. While the mechanism of pouchitis is still unknown, a role involving the bacterial flora is suspected. The aim of the present study is to investigate the association between pouchitis and change in the bacterial flora. METHODOLOGY: This study included 22 patients who underwent ileal pouch-anal anastomosis in our department to treat ulcerative colitis. The mean age was 46.2 years. The male-to-female ratio was 10:12. The mean interval between surgery and this study was 95.6 months. Collected feces was serially diluted 10-fold to 10-8 and each solution was cultured. We diagnosed pouchitis using the pouchitis disease activity index. RESULTS: Nine of the 22 patients were diagnosed as having pouchitis. In the obligate anaerobes, the numbers of Bacteroidaceae and Bifidobacterium were significantly lower in the pouchitis group (P<0.01 and P<0.001). In the facultative anaerobic bacteria, the number of Lactobacillus was significantly lower in the pouchitis group (P<0.05). CONCLUSIONS: The numbers of Bacteroidaceae, Bifidobacterium and Lactobacillus were significantly lower in the bacterial flora of the pouchitis group. Our findings suggest that there is an association between change in the bacterial flora and pouchitis.

Large-scale nosocomial outbreaks of Serratia marcescens septicaemia in Japan have had a fatality rate of 20-60% within 48 h. As a countermeasure, a real-time PCR assay was constructed for the rapid diagnosis of S. marcescens septicaemia. This assay indeed detected S. marcescens in clinical blood specimens (at ca. 10(2)CFU ml(-1)), at a frequency of 0.5% in suspected cases of septicaemia. In mice, the assay provided estimates of blood S. marcescens levels at various infectious stages: namely, 10(7) to 10(8)CFU ml(-1) at a fatal stage (resulting in 100% death), 10(4)-10(5)CFU ml(-1) at a moderately fatal stage (resulting in 50% or more death), and <10(3)CFU ml(-1) at a mild stage (resulting in 100% survival), consistent with actual CFU measurements. Blood bacterial levels could be an important clinical marker that reflects the severity of septicaemia. The simultaneous detection of S. marcescens and the carbapenem resistance gene was also demonstrated.
