ABSTRACT

BACKGROUND: The use of robot-assisted and laparoscopic pancreatoduodenectomy is increasing, yet large adjusted analyses that can be generalized internationally are lacking. This study aimed to compare outcomes after robot-assisted pancreatoduodenectomy and laparoscopic pancreatoduodenectomy in a pan-European cohort. METHODS: An international multicenter retrospective study including patients after robot-assisted pancreatoduodenectomy and laparoscopic pancreatoduodenectomy from 50 centers in 12 European countries (2009-2020). Propensity score matching was performed in a 1:1 ratio. The primary outcome was major morbidity (Clavien-Dindo ≥III). RESULTS: Among 2,082 patients undergoing minimally invasive pancreatoduodenectomy, 1,006 underwent robot-assisted pancreatoduodenectomy and 1,076 laparoscopic pancreatoduodenectomy. After matching 812 versus 812 patients, the rates of major morbidity (31.9% vs 29.6%; P = .347) and 30-day/in-hospital mortality (4.3% vs 4.6%; P = .904) did not differ significantly between robot-assisted pancreatoduodenectomy and laparoscopic pancreatoduodenectomy, respectively. Robot-assisted pancreatoduodenectomy was associated with a lower conversion rate (6.7% vs 18.0%; P < .001) and higher lymph node retrieval (16 vs 14; P = .003). Laparoscopic pancreatoduodenectomy was associated with shorter operation time (446 minutes versus 400 minutes; P < .001), and lower rates of postoperative pancreatic fistula grade B/C (19.0% vs 11.7%; P < .001), delayed gastric emptying grade B/C (21.4% vs 7.4%; P < .001), and a higher R0-resection rate (73.2% vs 84.4%; P < .001). CONCLUSION: This European multicenter study found no differences in overall major morbidity and 30-day/in-hospital mortality after robot-assisted pancreatoduodenectomy compared with laparoscopic pancreatoduodenectomy. Further, laparoscopic pancreatoduodenectomy was associated with a lower rate of postoperative pancreatic fistula, delayed gastric emptying, wound infection, shorter length of stay, and a higher R0 resection rate than robot-assisted pancreatoduodenectomy. In contrast, robot-assisted pancreatoduodenectomy was associated with a lower conversion rate and a higher number of retrieved lymph nodes as compared with laparoscopic pancreatoduodenectomy.

ABSTRACT

Background/aim: Giant ventral incisional hernias (GVIHs) are hard to manage for surgeons. This problem was resolved in 1990 with the components separation technique (CST). We aimed to compare endoscopic and conventional CST for GVIHs and find a new anthropometric calculation. Materials and methods: In this prospective nonrandomized clinical trial, 21 patients were treated with endoscopic or conventional CST between 2012 and 2016. Eight patients (38.1%) were operated endoscopically and 13 (61.9%) conventionally on the basis of preoperative tomography results, hernia surface area (HSA), number of recent abdominal operations, comorbidities, and the presence or history of ostomy. Groups in which prosthetic material was applied were also compared with groups in which it was not Results: There was no statistically significant difference between endoscopic and conventional CST groups in terms of complications. A weakly statistically significant difference (P = 0.069) was found between the components separation index (CSI) of mesh-applied and not-applied patients. HSA/body surface area (BSA) was statistically significantly different between endoscopic and conventional CST groups. Conclusion: According to our results, HSA/BSA and CSI are statistically successful for preoperative prediction of mesh placement. Furthermore, HSA/BSA preoperatively successfully predicts whether conventional or endoscopic CST should be used in patients with GVIH

ABSTRACT

BACKGROUND: Colorectal cancer (CRC) is a rare disease amongst children and adolescents. Previous studies have reported a number of differences between children/adolescents, young adults, and adult patients with CRC. However, none of these studies compared these age groups according to their clinicopathologic and prognostic characteristics. In the current study, we compare these three age groups. METHODS: A total of 173 (1.1% of 15,654 patients) young CRC patients (≤25 years) were included in the study. As a control group, 237 adult CRC patients (>25 years) were also included. Patients were divided into three age groups: child/adolescent (10-19 years), young adult (20-25 years), and adult (>25 years). RESULTS: Statistical differences amongst the three groups in terms of gender (p = 0.446), family history (p = 0.578), symptoms of presentation (p = 0.306), and interval between initiation of symptoms and diagnosis (p = 0.710) could not be demonstrated. Whilst abdominal pain (p < 0.001) and vomiting (p = 0.002) were less common in young adults than in other groups, rectal bleeding and changes in bowel habits were relatively less common in adolescents than in other groups. Rectal localisation (p = 0.035), mucinous adenocarcinoma (p < 0.001), and a poorly differentiated histologic subtype (p < 0.001) were less common in the adult group than in other groups. The percentage of patients with metastasis and sites of metastasis (e.g., peritoneum and lung) differed between groups. The median overall survival was 32.6 months in the adolescent group, 57.8 months in the young adult group and was not reached in the adult group (p = 0.022). The median event-free survival of the adolescent, young adult, and adult groups was 29.0, 29.9, and 61.6 months, respectively (p = 0.003). CONCLUSIONS: CRC patients of different age groups present different clinicopathologic and prognostic characteristics. Clinicians should be aware of and manage the disease according to these differences.

ABSTRACT

BACKGROUND: Nausea and vomiting are common postoperative complications that occur within the first 24 h in adults. Clinical practice guidelines and a Cochrane review recommend stimulating the P6 acupoint to prevent or reduce postoperative nausea and vomiting. However, there are currently no standards and optimal timing is not known. OBJECTIVES: The purpose of this study was to evaluate the effect of acupressure application on the P6 acupoint, using acupressure wristbands, in the prevention of postoperative nausea and vomiting and the antiemetic drug requirement in patients who had high postoperative nausea and vomiting risk related to laparoscopic cholecystectomy. DESIGN: This was a longitudinal, randomized controlled clinical study. SETTINGS: The study was conducted in the general surgery department of a training and research hospital (105 beds), from March 2015 to March 2016. PARTICIPANTS: A total of 111 female patients who underwent laparoscopic surgery were divided into three groups of 37, using a block randomization method. METHODS: Training on acupressure wristband use was provided to the intervention group and an acupressure wristband with a plastic cap was placed at the P6 acupoint. A wristband with the same appearance as the acupressure wristband, but without a cap, was used in the placebo group. No intervention was used in the control group. The wristband was placed approximately one hour before the surgery and removed six hours after the surgery in both the intervention and placebo groups. The data were collected at the 2nd, 6th, and 24th postoperative hours. RESULTS: The application of the acupressure wristband to the P6 acupoint in patients who underwent laparoscopic cholecystectomy was found to be more effective in decreasing the severity of nausea at the 2nd postoperative hour and the nausea incidence at 2-6 h, postoperatively, when compared to the placebo group (p < 0.05). However, there was no statistically significant difference between the intervention group and the control group. Therefore, acupressure application to the P6 acupoint was not found to be clinically effective in decreasing postoperative vomiting, antiemetic drug requirement, and in decreasing pain, anxiety, or the need for analgesic drugs (p > 0.05). CONCLUSIONS: We did not find the stimulation of the P6 acupoint with an acupressure wristband to be clinically effective in reducing postoperative nausea and vomiting or antiemetic drug requirement in patients who underwent laparoscopic cholecystectomy.

ABSTRACT

The main method of fighting against colon cancer is targeted treatment. BRAF inhibitors, which are accepted as standard treatment for V600E mutant malign melanomas, are the newest approach for targeted treatment of V600E mutant colorectal cancers. In this case report, we share our experience about the use of BRAF inhibitor vemurafenib on a V600E mutant metastatic right colon adenocarcinoma patient. A 59-year-old male with only lung multiple metastatic V600E mutant right colon cancer presented to our clinic. The patient was evaluated and FOLFOX + bevacizumab treatment was initiated, which was then continued with vemurafenib. A remarkable response was achieved with vemurafenib treatment in which the drug resistance occurred approximately in the sixth month. Even though the patient benefited majorly from vemurafenib, he died on the 20th month of the diagnosis. The expected overall survival for metastatic V600E mutant colon adenocarcinoma patients is 4.7 months. BRAF inhibitors provide new treatment alternatives for V600E mutant colorectal cancers, with prolonged overall survival. BRAF inhibitors in combination with MEK inhibitors are reported as feasible treatment to overcome BRAF inhibitor drug resistance on which phase studies are still in progress. To conclude, BRAF inhibitors alone or in combination with other drugs provide a chance for curing BRAF V600E mutant colorectal cancer patients.

ABSTRACT

BACKGROUND: Intraabdominal adhesions remain a significant cause of morbidity and mortality. Moreover, intraabdominal adhesions can develop in more than 50% of abdominal operations. AIMS: We compared the anti-adhesive effects of two different agents on postoperative adhesion formation in a cecal abrasion model. STUDY DESIGN: Experimental animal study. METHODS: Forty Wistar albino type female rats were anesthetized and underwent laparotomy. Study groups comprised Sham, Control, Mitomycin-C, 4% Icodextrin, and Mitomycin-C +4% Icodextrin groups. Macroscopic and histopathological evaluations of adhesions were performed. RESULTS: The frequencies of moderate and severe adhesions were significantly higher in the control group than the other groups. The mitomycin-C and Mitomycin-C +4% Icodextrin groups were associated with significantly lower adhesion scores compared to the control group and 4% Icodextrin group scores (p=0.002 and p=0.008, respectively). The adhesion scores of the Mitomycin-C group were also significantly lower than those of the 4% Icodextrin group (p=0.008). CONCLUSION: Despite its potential for bone marrow toxicity, Mitomycin-C seems to effectively prevent adhesions. Further studies that prove an acceptable safety profile relating to this promising anti-adhesive agent are required before moving into clinical trials.

ABSTRACT

BACKGROUND: Evidence on the effectiveness of using a binder following abdominal surgery and its effect on gastrointestinal function, mobilization, pulmonary function, and pain is currently unclear. OBJECTIVE: The purpose of this study is to determine the effect of abdominal binder usage on gastrointestinal function, mobilization, pulmonary function, and postoperative pain in patients undergoing major abdominal surgery. DESIGN: This research was conducted as a randomized controlled trial. SETTINGS: The study was conducted at the Department of General Surgery at a military education and research hospital in Ankara, Turkey, between September 2013 and April 2014. PARTICIPANTS: 104 patients were assessed for eligibility. The study was conducted on 84 eligible patients. METHODS: The study sample consisted of 84 patients who underwent effective major abdominal surgery. The patients were randomized into two groups, the intervention group, which used an abdominal binder and the control group, which did not. Gastrointestinal function, mobilization, pulmonary function, and the pain status of both groups were evaluated on the first, fourth, and seventh days before and after surgery, and the intergroup results were compared. RESULTS: No significant difference was found between the two groups in terms of gastrointestinal and pulmonary function on the first, fourth, and seventh days following surgery (p>0.05). A comparative assessment of mobility by walking distance showed that patients in the intervention group were able to walk further on the fourth [mean (SD); 221.19 (69.08) m] and seventh [227.85 (60.02) m] days after surgery (p=0.003, p<0.001). There were differences in the acute pain status between patients in both groups (p<0.05). On the first [mean (SD); 8.80 (5.03)], fourth [4.83 (2.78)], and seventh [3.09 (3.17)] days after surgery, the sensory sub-scale pain scores were higher in the control group (p<0.001). On the first [mean (SD); 10.16 (6.14)], fourth [5.28 (3.52)], and seventh [3.30 (3.51)] days after surgery the total pain scores were higher in the control group (p<0.001). The visual analogue scale scores were also higher in the control group on the first [mean (SD) 6.26 (1.86)], fourth [4.50 (2.10)], and seventh [3.04 (2.43)] days after surgery (p<0.001). CONCLUSION: The study's findings reveal that the use of an abdominal binder does not have any effect on postoperative gastrointestinal and pulmonary function. However, an abdominal binder increases patient mobility soon after surgery. There was also a measurable effect on pain, with lower scores reported by patients who used an abdominal binder after any exercise or activity. These results indicate that the use of a routine abdominal binder is helpful for patients undergoing major abdominal surgery.

ABSTRACT

BACKGROUND/PURPOSE: The presentation of scientific studies at major meetings serves to rapidly share study results with the scientific community. On the other hand, full-text publication of abstracts in peer-reviewed journals ensures the dissemination of science. This study examines the publication rate (PR) of meeting abstracts presented at the European Society for Surgical Research (ESSR) congresses and determines/compares the factors affecting the PRs. METHODS: All presentations at the ESSR congresses held during 2008-2011 were retrospectively assessed. Manuscripts indexed in PubMed were included. The meeting year, journal impact factor (IF) in the publication year, study type, presentation type, time to publication and geographic origin of studies were assessed. RESULTS: Among a total of 1,368 oral and poster abstracts, 48.7% (n = 391) of the oral presentations (OPs) and 29.7% (n = 168) of the poster presentations (PPs) were published in medical journals indexed in PubMed. The mean IF of the journals was 2.696 (0.17-14.95). The journals that published OPs had a higher IF than the journals in which PPs were published (2.944 vs. 2.118; p < 0.001). The PR was also higher in the OP group than in the PP group of journals (p < 0.001). The time to publication was 17.5 months (-166 to 82) and was shorter for PPs than for OPs (14.02 vs. 19.09 months; p = 0.01). According to the study type, experimental studies had a significantly higher PR (53.7%; p < 0.001); however, there was no significant difference in PR in terms of the prospective or retrospective nature of clinical studies. The clinical studies were also compared according to the IF values of the journals in terms of the prospective or retrospective nature of the study, and no significant difference was found (p = 0.62). CONCLUSION: The ESSR congress is an efficient meeting for researchers from varied surgical disciplines and has a PR equivalent to that of similar scientific meetings. The congress has achieved a PR of 40.9% over 4 years with an average IF of 2.696 and a mean time to publication of 17.5 months, which is equivalent to that of similar scientific meetings. OPs have a higher PR in journals with greater IF values as compared with PPs.

ABSTRACT

AIMS AND OBJECTIVES: To compare the comfort levels of patients regarding the use of three different graduated compression stockings and to analyse the efficacies of the graduated compression stockings in relation to patient comfort and compliance in prevention of postoperative deep vein thrombosis. BACKGROUND: Graduated compression stockings are very important with other prophylaxis methods in postoperative deep vein thrombosis prophylaxis. In meta-analyses and systematic review studies, it was reported that knee-length and thigh-length graduated compression stockings had similar efficacies. However, there is no randomised study in literature regarding the patient problems and levels of comfort with the use of graduated compression stockings of different sizes and pressures. DESIGN: A randomised clinical trial design. METHODS: A total of 219 patients were randomised into three groups (n = 73 in each group). Group I was given low-pressure, knee-length graduated compression stockings, group II was given low-pressure, thigh-length graduated compression stockings and group III was given moderate-pressure, knee-length graduated compression stockings. The level of patients comfort regarding the graduated compression stockings and occurrence of deep vein thrombosis were examined. RESULTS: The vast majority of the patients (79·5%) in group III and 52·1% of the patients in group II stated experiencing problems during the use of the graduated compression stockings (p < 0·001). The graduated compression stockings were reported by the patients as being very comfortable in the group I (p < 0·001). No findings of thrombosis were observed in any of the groups. CONCLUSION: The low-pressure, knee-length graduated compression stockings are as effective as the other graduated compression stockings of different pressures and sizes in the postoperative deep vein thrombosis prophylaxis, and the patients have fewer problems while using these graduated compression stockings with a high satisfaction. RELEVANCE TO CLINICAL PRACTICE: The combined use of pharmacological, mechanical and physical methods and patient education is effective in the prevention of postoperative deep vein thrombosis. The use of low-pressure, knee-length graduated compression stockings in clinical practice may be recommended, as the patients have fewer problems while using these graduated compression stockings with a high satisfaction.

ABSTRACT

Evolutions in minimally invasive surgical techniques and advances in sentinel node navigation surgery (SNNS) have had considerable impact on current insights into surgical treatment of gastric cancer. Extensive data on this method of surgical application have accumulated but have been principally derived from single-institute studies. Isosulfan blue and patent blue violet have been the most frequently used dye tracers in the past; however, indocyanine green has now is increasingly popular. The double-tracer method, where dye and radioisotope tracers are used together, seems to be more effective than any single tracer. Among newly emerging adjunct techniques and promising alternative in particular are infrared ray electronic endoscopy, florescence imaging, nanoparticles, and near-infrared technology. Hematoxylin and eosin (H&E) staining is still the method of choice for the detection of sentinel lymph node (SLN) metastases. Immunohistochemical staining can be used to support H&E findings, but the equipment costs of ultrarapid processing systems are currently slowing down their worldwide spread. We believe minimally invasive function-preserving resection of the stomach, together with lymphatic basin dissection navigated by SLNs, can represent the ideal approach for SNNS to detect clinically node-negative early gastric cancer, although this remains to be elucidated. Patients with cT3 or more advanced disease should still be treated by means of standard D2 dissection.

ABSTRACT

Liver resection (LR) and primary liver transplantation (LT) are two potentially curative treatment modalities for patients with hepatocellular carcinoma (HCC). If an underlying chronic liver disease exists, however, making a decision on which method should be selected is difficult. If a patient has no chronic liver disease, LR may be the preferable option with salvage transplantation (ST) in mind in case of recurrence. Presence of a moderate-to-severe liver failure accompanying HCC usually warrants primary LT. The treatment of patients with HCC and early-stage chronic liver disease remains controversial. The advantages of "LR-followed-by-ST-if-needed" strategy include less complicated index operation, no need for immunosuppression, use of donor livers for other patients in today's organ shortage setting and comparable survival rates. However, primary LT has its own advantages as it also treats underlying chronic liver disease with carcinogenic potential, removes undetected tumor nodules and potentially eliminates need for a ST. An article recently published by Fuks et al in Hepatology offers an approach by which selecting between LR-followed-by-ST and immediate LT might be easier. Here we discuss the results of the aforementioned report in the light of currently available knowledge.

ABSTRACT

The aim of the present study was to investigate the effect of hyperbaric oxygen therapy (HBOT) on colon anastomosis after chemoradiotherapy (CRT). Sixty female Wistar-Albino rats were divided into 5 groups and underwent left colon resection and end-to-end anastomosis. CRT simulation was performed on 2 sham groups before the anastomosis, and 1 of these groups was administered additional postoperative HBOT. Two groups were administered CRT before the anastomosis, and 1 of them received additional postoperative HBOT. On postoperative day 5, all groups underwent relaparotomy; burst pressure was measured and samples were obtained for histopathologic and biochemical analysis. There was a significant weight loss in the CRT groups and postoperative HBOT had an improving effect. Significantly decreased burst pressure values increased up to the levels of the controls after HBOT. Hydroxyproline levels were elevated in all groups compared to the control group. Hydroxyproline levels decreased with HBOT after CRT. No significant difference was observed between the groups regarding fibrosis formation at the anastomosis site. However, regression was observed in fibrosis in the group receiving HBOT after CRT. Preoperative CRT affected anastomosis and wound healing unfavorably. These unfavorable effects were alleviated by postoperative HBOT. HBOT improved the mechanical and biochemical parameters of colon anastomosis in rats.

ABSTRACT

The aim of this report is to assess clinical findings and surgical treatment of left paraduodenal hernia, which is an unusual type of internal herniation, in light of the literature. The diagnosis and treatment course of a 42-year-old male patient with findings of intestinal obstruction was assessed and presented together with literature search. The patient underwent surgery with a preliminary diagnosis of intestinal obstruction and the definitive diagnosis of internal herniation was made intraoperatively. Nearly two-thirds of the small intestine was found to be herniated into the retroperitoneal space from the left paraduodenal region. Small bowel loops were pulled out of the hernia sac and anatomically positioned in the intraperitoneal area. The hernia sac was repaired primarily. The patient was discharged on the fourth postoperative day, uneventfully. Left paraduodenal hernia should be considered as a part of differential diagnosis in patients who have recurring abdominal pain episodes accompanied by symptoms suggestive of intestinal obstruction. Timely diagnosis is important to prevent complications. Reduction of hernia content followed by primary repair of the defect appears to be a safe and effective treatment.

ABSTRACT

Development of sentinel node navigation surgery (SNNS) and advances in minimally invasive surgical techniques have greatly shaped the modern day approach to gastric cancer surgery. An extensive body of knowledge now exists on this type of clinical application but is principally composed of single institute studies. Certain dye tracers, such as isosulfan blue or patent blue violet, have been widely utilized with a notable amount of success; however, indocyanine green is gaining popularity. The double tracer method, a synchronized use of dye and radio-isotope tracers, appears to be superior to any of the dyes alone. In the meantime, the concepts of infrared ray electronic endoscopy, florescence imaging, nanoparticles and near-infrared technology are emerging as particularly promising alternative techniques. Hematoxylin and eosin staining remains the main method for the detection of sentinel lymph node (SLN) metastases. Several specialized centers have begun to employ immunohistochemical staining for this type of clinical analysis but the equipment costs involving the associated ultra-rapid processing systems is limiting its widespread application. Laparoscopic function-preserving resection of primary tumor from the stomach in conjunction with lymphatic basin dissection navigated by SLN identification represents the current paramount of SNNS for early gastric cancer. Patients with cT3 stage or higher still require standard D(2) dissection.

ABSTRACT

BACKGROUND: There is still no consensus as to the optimal treatment for sacrococcygeal pilonidal disease (SPD). Many recommend off-midline closure, if any excisional procedure is to be selected. METHODS: The authors prospectively studied 145 patients with SPD who presented at 3 hospitals. Patients were randomly assigned to undergo either modified Limberg flap (MLF) transposition (n = 72) or Karydakis flap reconstruction (n = 73). Surgical findings, complications, recurrence rates, and degree of patient satisfaction, evaluated via a standardized telephone interview, were compared. RESULTS: Operation time was longer in the MLF group. There were no significant differences between the two groups in terms of complication rate, length of stay, or recurrence rate. Patients in the Karydakis group reported feeling completely healed more quickly postoperatively. The two groups reported similar rates of satisfaction. Mandatory patient withdrawal from a given study arm because of the orifice straying from the midline occurred more frequently in the Karydakis group. CONCLUSIONS: The MLF technique and the Karydakis procedure appear to generate comparable outcomes. With laterally situated orifices, however, the applicability of the Karydakis method may be limited.

ABSTRACT

OBJECTIVE: The aim of the study was to investigate the effects of different resuscitative fluids on the healing of intestinal anastomosis in a hemorrhagic-shock rat model. MATERIALS AND METHODS: Closed-colony Wistar male rats (n = 40; 8 rats per group) were subjected to volume-controlled hemorrhagic shock, followed by a 30-min shock phase. The animals were then resuscitated with one of the following fluids (which also corresponds to their respective groups): lactated Ringer's solution (LR), hydroxyethyl starch (HES), 7.5% hypertonic saline (HS) and autologous blood (AB). There was also a control group (CL), which did not experience hemorrhagic shock or receive any resuscitative fluids. All rats underwent laparotomy, segmental resection and anastomosis of the left colon. Five days later, a 2nd laparotomy was performed and the anastomotic bursting pressure was measured in vivo. Thereafter, the anastomosed segment was resected to measure the tissue hydroxyproline level and the grade of anastomotic fibrosis. RESULTS: All experimental groups (LR, HES, HS and AB) exhibited lower anastomotic bursting pressures than the CL group; however, no intergroup differences achieved statistical significance. The mean tissue hydroxyproline level and fibrosis grade also were similar across all 5 groups. CONCLUSION: In traumatic hemorrhagic shock, anastomosis safety does not appear to be affected by the type of fluid used for resuscitation. Moreover, LR, HES and HS all seemed to reinforce healing as effectively as transfused blood.

ABSTRACT

PURPOSE: There is a high incidence of sacrococcygeal pilonidal disease (SPD) among young males. Despite increasing data on the treatment of SPD, no standard treatment has yet been established. The goal of this study was to compare the Karydakis flap reconstruction with a primary midline closure (PMC) in the treatment of patients with SPD. METHODS: The study included 200 patients treated over a period of 30 months. After a power analysis, the study was run on a two-directional basis (both retrospective reviews of patient charts and a telephone interview for prospective evaluation). The surgical findings, complications, recurrence rates, and degree of satisfaction based on a questionnaire were assessed. RESULTS: The duration of the surgery was longer in the Karydakis group. Complications were more frequently seen in the PMC group. The recurrence rate was 4.6% for the Karydakis group and 18.4% for the PMC group. Of patients who underwent the Karydakis operation, 70.8% were completely satisfied with the procedure, while only 32.6% of patients who underwent the PMC reported excellent satisfaction. A significantly higher number of patients in the Karydakis group recommended the same procedure to other patients with SPD. CONCLUSION: The Karydakis method may be a preferable option in the treatment of SPD, due to the low rate of recurrence and the promising satisfaction rates.
